Population Control and The Origins of the 3rd World Essay
Population Control and The Origins of the 3rd World - Essay Example This Malthusian presumption exists in the contemporary times as a popular clarification for environmental degradation and poverty. The third world is presumed to have resulted from the consequence of wealth and income disparities that were established in the final parts of the nineteenth century. This was when famous non-European peasants were incorporated in the world financial system (Davies 1). Malthus exonerates the unit of individuals who own property and the political economic system by implying that the productivity of the underprivileged is the foremost source of their underprivileged position, and that the productivity of the underprivileged cannot be tremendously affected by human involvement. In India, after 1876, the collective terror of the drought-famine extension from southern Indian cost to the North Western Provinces semi-arid areas of India. The loss of food products in a number of districts was disastrous. The peasants in every district traded the frames of their d oors and windows, field apparatus, the hatch of the roofs, and bullocks to stay alive during the initial period of the drought (Davies 2). They could not make use of the minimal rain produced between April and May due to lack of adequate means of production. Question 2 Malthusian reasoning still prevails because of a number of reasons. First, archeologists illustrate that societies surface when cultivators can produce an extra amount of food than they and their households can consume. It is the surplus of the cultivators that makes a society probable. Nevertheless, there are a number of minimal omissions where individuals have different products apart from agriculture with which they can exchange, for example, copper, automobile, or gold. Nonetheless, it is similar in all instances, if there is no product surplus, there will be no society (Davies 7). In addition, the thinking is still relevant because food is essential to the survival of humans. Also, the passion among the sexes is significant, and will linger in its current form. The law on food and passion among the sexes seem to have been permanent rules of the human nature. Moreover, human beings cannot conclude that these laws will stop being what they are without an instant act of influence in that being for the benefit of human beings and the system of the globe. By the rule of human nature which makes foodstuff essential to the existence of human beings, the impacts of the uneven influences should be kept at per. This entails a stout and continuously functioning assessment on population from the complexity of survival (Davies 23). This complexity should be placed somewhere, and should unavoidably be extremely felt by a significant section of humans. Moreover, the persistent endeavor towards population enhances the number of humans prior to the increment of the means of subsistence. Question 3 Malthusian views assert that disease and famine are the consequence of overreproduction, so victims should not be prevented from perishing. It is this Malthusian reasoning that has caused large amounts of death in several parts of the globe. First, there is forced inclusion of smallholder making into financial circuits and products all over the globe supervised from out of the countries. This destabilizes conventional food security. The underprivileged are compelled into progressive decline of circumstances of loss of property

Crime is Predominantly an Intra-Racial Event Essay Example for Free
Crime is Predominantly an Intra-Racial Event Essay Introduction: Society has this perception that it is other races why crime occurs. Some people blame these crimes on black-on-black crimes, or Hispanics-on-Hispanics crimes. Being that crime seems to be predominantly an intra-racial event involving victims and offenders of the same race; will this type of destruction ever come to an end? While interviewing two of my co-workers while we were on break in between our runs, it was very interesting to learn of their intakes on this particular topic. The first co-worker I talked to is Hispanic. His name is Steven. Steven agrees that crime in a way is predominantly an intra-racial event, involving victims and offenders of the same race. Steven relates Hispanic-on-Hispanic intra-racial crime because of economic gaps in society. Steven feels that Hispanics are always given such a hard time when it comes to getting jobs. Hispanics are always first asked if they have a green card and can they legally work here in the United States. Steven says this comes from his own experience in trying to get a job as a mechanic. He felt very offended because of the stereotypes that society put on people of his origin. Steven says that he may be Hispanic but he was born and raised here in the United States. His parents were in the military, where they were stationed in San Antonio, Texas. His parents are from San Juan, Puerto Rico. Steven feels that this intra-racial crime comes from Hispanics having a lack of work and education to support their families. Steven has witnessed his own people killing one another over fearing being deported back to their country. Hispanics cross the border so that they can raise their families in a better environment with better opportunities. The second co-worker I talked to is African-American. His name is Chuck. Chuck’s outlook on intra-racial crime is very similar to Steven’s outlook. Chuck feels that intra-racial crimes are a choice. Chuck grew up watching black-on black crimes like gangs killing other gangs because of crossing into their territory. Chuck says that society plays a big part in why blacks act the way that they do. He believes that society puts out negative stereotypes about blacks and people run with it. Chuck says black-on-black crime comes from a number of things like kids killing kids with illegal guns found in their houses, drug deals gone bad, young black men fighting in the clubs over females or fighting in the streets over a senseless argument. Crime Is Predominantly an Intra-Racial Event 2 Both Steven and Chuck agree that no matter what the situation may be, these unfortunate intra-racial crimes should not even occur. They both feel that people need to get a better education and obtain some type of work skill which is positive. Conclusion Intra-racial crimes leave families in disarray. Black-on-black crimes can be avoided if they are yes, re-educated and taught a trade to learn a meaningful skill. These crimes can be cut down tremendously and the African-American race can begin rebuilding. Hispanic-on-Hispanic crimes could also be cut in half if those who are here in the United States legally or who have their green cards, could go to school and get and education and earn a degree to help better them. Hispanics could also go to a trading school and get the skills that they need to find decent work. This way, Hispanics do not have to be paid under the table and they can earn a decent paycheck to help in supporting their families. The victims in these intra-racial crimes are the ones who have been hurt and families destroyed. The offenders in these intra-racial crimes just make excuses why they did as they feel that they had to do. Many offenders have no remorse for their actions and to them, it is everyone else’s fault but their own.

Data Analysis Chapter Analysis
Data Analysis Chapter Analysis Part One: Based on my NTU username (N0687816), my data set is: (0,6,8,7,8,1,6) Section A) Forming a 99% confidence interval for my data set:   Our confidence interval is: We can therefore say with 99% confidence that the mean number of tattoos per student for the population of all students at NTU is between 0.54 and 9.74 Using Minitab for a 99% confidence interval for data set (0,0,0,1,3,3,7): Section B) Looking for evidence at the 97% confidence level of a difference between the samples: Sample 1 (0,6,8,7,8,1,6) Sample 2 (0,0,0,1,3,3,7) Sample sizes Sample means Sample variances I am going to use a two-sample T test to analyse this data as there are two small samples formed from data that is not paired. We can say with 97% confidence that there is no difference between the two samples. Using Minitab: Section C) Testing data from trialing a new inhaler Person 1 Person 2 Person 3 Person 4 Person 5 Person 6 Person 7 Before 0 6 8 7 8 1 6 After 0 0 0 1 3 3 7 To analyse this data, I will use a paired T-test as there are two sets of data for the same group of people (before and after using an inhaler). It is also unknown if the data is normally distributed and the sample is small which are both other factors which suggest the use of a T test. This test could be one or two tailed depending on whether you were looking for an improvement/reduction or a general change. In this case, however, we want the inhalers to have improved the peoples lung function so we will do a one tailed test. Null hypothesis Alternative hypothesis. (The data is for recovery time in seconds so a reduction in the mean recovery time shows an improvement in lung function). Decision Rule: Performing the test: Let So There is not a specified confidence interval so I will use a 95% confidence interval so: Therefore:   We can therefore say with 95% confidence that the inhaler did improve the lung function of the people who used it. Testing the Manufacturers Claim I am going to use a one tailed hypothesis test. This is because it does not matter if the inhaler improves lung function in over 80% of cases, only if it does not reach this claim. I will take to be that and to be that . The lung function recovery time reduced in four of the seven trials so 4 events out of 7 trials, leading to and Part Two: Section A) The Lady Tasting Tea Experiment The lady tasting tea experiment was a statistical experiment conducted by Ronald Fisher. As explained in The lady tasting tea experiment (Winkler, 2015), a lady claimed she could tell whether milk or tea was poured first in a cup of tea she tasted. Ronald Fishers book The Design of Experiments (see Winkler, 2015) outlined the ideas behind this test: [It] consists in mixing eight cups of tea, four in one way and four in the other, and presenting them to the subject for judgement in a random order. The subject has been told in advance [à ¢Ã¢â€š ¬Ã‚ ¦] that she will be asked to taste eight cups, that these shall be four of each kind Fisher, 1935. According to Imai (2016), Fisher introduces the idea of a null hypothesis, which in this case, is the idea that the woman is guessing and cannot actually distinguish between the cups. Fisher then used the ladys answers to work out the likelihood of her getting this result whilst guessing. From this, he found that there were 70 ways to choose 4 cups out of 8 and that from these, there was 1 way of getting none and four correct, 16 ways of getting one and three correct and 36 ways of getting two correct, as shown by Inglis-Arkell (2015). Although pioneering, however, the test itself was not powerful. As explained by Stark (2010), the small sample size caused the probability of her guessing randomly only coming out less than 0.05 (the condition required to reject the null hypothesis) if she got a perfect score. This is because guessing all four correctly carried a probability of whereas guessing three out of four correctly carried a probability of . This issue would have been reduced with a much bigger sample size. For another mathematical example, we will look at the following question: Suppose the lady samples 10 cups of tea, among which 5 had the teapoured first and 5 had the milk poured first.a. What is the probability she correctly identifies all five cups which had the tea poured first? Sloughter, 2006. Following the logic displayed by Stark (2010) for the lady tasting tea problem, there would be only 1 way of choosing all five correctly. Using the formula (Simmons, 2016), we get ways of choosing five cups of tea out of the ten. This means that the probability of getting all five correct is . As stated by Inglis-Arkell (2015), the number of cups that the lady guessed correctly is unknown. Despite this, the lady tasting tea experiment is still extremely influential and led to Ronald Fisher being praised for his book The Design of Experiments due to how clearly he explained why randomisation is important and how he decided what would be acceptable evidence to accept or reject a statement.

Essay --
In recent years, light olefins are used as building blocks for a large variety of chemicals and petrochemicals products that are produced from crude oil. Light olefins are in a class of hydrocarbons with a single double bond and a chemical formula of CnH2n. Ethylene and Propylene are the most important olefins which form the backbone of the petrochemicals market. However, ethylene and propylene have no end use. The highly reactive double bond of the ethylene and propylene makes the molecule ideal for conversion to many useful product such as polymers (eg. polypropylene, polyethylene and polyvinyl chloride), synthetic rubber and fuel components. Currently, most olefins are produced via thermal cracking of naphtha or other light fractions of petroleum with steam, which is often referred to as steam cracking. During the process, the hydrocarbon feedstock which usually of fossil origin, is cracked into smaller molecules. The process is innovative olefin technologies in terms of energy efficiency. The resulting product mix from the cracking process which varies depending on the process c...

Principles Of Behaviorism Essay
The principles of behaviorism are represented through a sequence of events and possibly lead to â€Å"time-out†period. Time-out is used by parents as a disciplinary tool towards their misbehaving child. Parents respond to a child’s actions through reinforcement, whether it be expressed by a positive or negative feedback. When a child does something unacceptable or troublesome the parent may use seclusion as a type of punishment known as â€Å"time-out.†After the child has done something wrong they must sit in a quiet area by themselves and ‘think about what they had done wrong.’ The time-out isolation usually is dismissed after the child has â€Å"cooled down†and acknowledges their behavior and is ready to act appropriately. Time-out usually influences a child’s behavioral development by learning the consequences of disobedience. This type of reinforcement could have many consequences based on the parent’s discretion. Some parents may use the threat of deprivation as a further penalty. The removal of the child’s TV, video games, cell phone or time with friends may be taken away until the child has fully understands why they are being punished. If the parents have successfully reinforced the child’s behaviors throughout development, the child should not be repeating a punishment for the same bad behavior that was once acknowledged. The child’s behavior should have already been handled and the frequency of misbehaving should decrease.

Only One Way to Stop a Bully Essay
Bullying has become a major issue in the past 5 years. This is something we hear of way too often whether it is at school, work, or even on the news. Bullying is not your typical kid who steals a student’s lunch money either; there are several cases worldwide that have ended in suicide for some. When it comes down to the severity of suicide or even physical harm that is when it’s no longer just a simple slap on the wrist, but rather a closer, deeper look into what we can start doing to change this and fast. In There’s Only One Way to Stop a Bully, an essay written by Susan Engel and Marlene Sandstrom they speak about this issue in depth. Sandstrom and Engel speak of specific ways we as a community and faculty at schools should incorporate lessons on how to deal, recognize, and solve bullying in everyday life. The authors also speak of a new law that has been passed in order to address and stop bullying. They support this claim by providing us with examples. One example is telling us of ideas that teachers have put to the test to defeat this issue, such as a teacher enforcing a rule that students could not exclude anyone from their play and the positive impact this brought. Sandstrom and Engel also support this by telling us of a school in Norway that has put much emphasis on this issue and by doing so, have succeeded in lowering the bullying rate. Although the authors brought valid points, there are a few key factors missing from this essay. One being that when Sandstrom and Engel introduced this new law that was passed to target bullying, they did not go into enough detail as far as the specifics of this law. What are the consequences of this law? It states that the most serious cases of bullying should be reported to law officials but at what degree do they consider bullying serious? I found myself asking these questions when reading the essay. This particular law was such a big part of the essay; I felt that more emphasis was needed. Another weakness I found in this essay was that I did not feel like it was so much an argumentative piece of writing but rather an essay informing me of instances and facts. In argumentative writing I always find myself stopping to relate, or to agree/disagree with the author on the topic. Although the authors made great points, while reading this I did not once stop to react to what the author was supposed to be â€Å"arguing†. There were many things that I enjoyed about this essay and brought me a positive outlook on this topic. The author used a lot of examples making it easy to read and make sense of the main claim. For instance, the author spoke of the success this law has made possible by speaking of Norway, a school who has really recognized this issue and applied it to their curriculum. The author also noted a teacher in particular who has enforced a specific rule in helping eliminate bullying. Rather than speaking of instances in a plain matter the author used specific examples and listed persons in particular bringing the realness of the matter to life.
Investigate The Christology Of Matthews Gospel Essays - Religion
Investigate The Christology Of Matthew's Gospel Essays - Religion Investigate The Christology Of Matthew's Gospel Matthews Christology is one that emphasises to a Jewish audience the Jewishness of Jesus. It will be the purpose of this paper to argue that the raison detre of Matthews Christology is to portray Jesus as entirely compatible if not with the Judaism of his day then with ancient Judaic tradition, namely the Old Testament. Whilst there are numerous titles given to Jesus that are exclusive/predominant within the Matthean account, such as that of Son of God, it is the writers assertion that these merely complement Matthews central theses; this being the portrayal of Jesus as Messiah and so, as such, will not be investigated except where they promote this conclusion. This fulfilment of Judaic tradition will be investigated in three separate yet interrelated areas: Jesus as the fulfilment of Hebraic messianic expectation, Jesus role as a Jewish teacher and Jesus as inaugurator of Gods Kingdom. Matthew is a Semitic gospel written as an encouragement to Jewish Christians and as an apologetic to unbelieving Jews. From the outset Matthew identifies Jesus as one of royal Davidic lineage and Abrahamic descent. Matthew immediately identifies with Judaic tradition portraying Jesus with the Immanuel figure of Isaiah 7:14 (1:23). This motif of the Jewishness of the gospel is especially prevalent in its depiction of Jesus role as the fulfilment of the Old Testaments messianic hope (2:4, 26:63) as well as running throughout the text on varying levels. Perhaps one of the most interesting theories offered in detailing this continuation between testaments is Leskes proposal that Jesus role and ministry is antecedent to the Isaianic literature, and, in particular, the Servant nation of Israel. Whilst a comprehensive critique of Leskes argument is outside the scope of this study, it would seem fair to concur that Matthew does indeed identify Jesus with the Servant (cf. 3:17; Isaiah 42:1). Consequently, we see in Matthews depiction of Jesus a fundamental tenet of Israels theological history personified. Jesus is, as the Messianic Servant, shown to be the fulfilment of further Isaianic prophecy, that of the suffering Servant. Throughout Matthews gospel there are six direct allusions to Isaiah 53 indicating a definite link and identification by Matthew with this Israelite and Messianic hope. Further, Farmer suggests that direct allusions notwithstanding in 20:20-28 and especially 26:26-30 Isaiah 53's redemptive hope is supposed to be fulfilled through Jesus description of the outcome of his crucifixion. Isaianic prophecy aside it is also clear that Matthew above the other three evangelists presents Jesus as the fulfilment of the law, a new Moses. The structure of the book into five sections is intended to help the Jewish readers identify Jesus as an antecedent of Moses. Jesus is according to some scholars a type of Moses bringing about a new exodus and a new Israel. More explicitly however, Matthew portrays Jesus as the only man to have fulfilled the law in its entirety as well as the messianic fulfilment of Old Testament prophecy through the many formula quotations (3:15; 5:17-48;12:17-21; 13:35; 21:5, 16, 42; 22:44; 23:39; 26:31; 27:9, 35, 46). Judaism as a religion placed great stress on the role of the rabbi or teacher, the concept of a teacher having students/disciples is ancient, Elijah and Elisha being cited as examples(1 Kings 19:19-21). In the Judaism of Matthews time such relationships were symptomatic of the religious climate with the array of schools of disciples that existed. It is not surprising then that Matthew in addressing recent adherents to this religion should portray Jesus as a teacher with his own band of disciples albeit a distinctive one. Whilst it must be noted with France that in comparison with Mark Matthew uses the term rabbi infrequently this should not be taken to mean Jesus as teacher is an inappropriate title to Matthew. Clearly, Jesus is revealed as Messiah far more explicitly than in the other synoptics but, Jesus nonetheless describes himself as a rabbi (3:15; 5:17-48; 11:27; 13:10-17; 23:8) and others recognized his similarity to other teachers and thus addressed him as such (8:19; 9:11; 1 2:38; 17:24; 19:16; 22:16, 24, 36). As teacher Jesus is portrayed as the revealer of Gods will and Israels true teacher and as such one of the central motifs of

The Importance of Being Earnest Review
'The Importance of Being Earnest' Review ​​The Importance of Being Earnest is Oscar Wildes most well-known and best-loved play, as well as being an enormous success in his lifetime. For many people, it is the apogee of Wildes work. Like Wilde, the play is the very embodiment of fin de sieclà © British dandyism. However, this seemingly frivolous play has a much darker side. Its critique of Victorian societythough delivered in a velvet gloveis every inch an iron fist. The play is a satire both of the hypocrisies of the society in which Wilde lived, and the damaging effect that these hypocrisies can have on the souls of those live under their rule. Wilde was to become one of those souls shortly after the first performance of the play when he initiated a libel trial that was to lead to his imprisonment for being a homosexual.​ Overview ofThe Importance of Being Earnest The play is based around two young men, one of whom is an upright young man called Jack who lives in the country. However, in order to escape the drudgery of his highly conservative lifestyle, he has created an alter-ego, Ernest, who has all kinds of reprobate fun in London. Jack says he often has to visit his poor brother Ernest, which gives him his opportunity to escape his boring life and have fun with his good friend, Algernon. However, Algernon comes to suspect that Jack is leading a double life when he finds a personal message in one of Jack’s cigarette cases. Jack makes a clean breast of his life, including the fact that he has a young and attractive ward by the name of Cecily Cardew back on his estate in Gloucestershire. This piques Algernons interest and, uninvited, he turns up on the estate pretending to be Jack’s brotherthe reprobate Ernestin order to woo Cecily. In the meantime, Jacks fiancà ©e, (and Algernons cousin) Gwendolen has also arrived, and Jack admits to her that he is, in fact, not called Ernest, but is called Jack. Algernon, despite his better judgment, also confesses to Cecily that his name is not Ernest either. This causes a good deal of trouble in our heroes love lives, as both women have a rather strange attachment to the name Ernest, and cannot consider marrying anyone who does not go by that name. There is another impediment to the marriages. Gwendolens mother, Lady Bracknell, will not countenance her daughter marrying someone of Jacks social status (he was an orphan who was found by his adoptive parents in a handbag at Kings Cross Station). As Jack is Cecilys guardian, he will not allow her to marry Algernon unless his aunt, Lady Bracknell changes her mind. This seemingly irresolvable conundrum becomes brilliantly solved when, on inspection of the handbag, Lady Bracknell reveals that Algernons brother had become lost in just such a handbag and that Jack must, in actuality, be that lost child. What’s more, the child had been christened Ernest. The play ends with a prospect of two very happy marriages. The Importance of Being Earnest combines a labyrinthine plot, the seemingly irresolvable narrative of a farce, and some of the most comic and wittiest lines ever written. It is, as can probably be surmised from its extraordinary to-ings and fro-ings and its incredibly unlikely resolution, is not to be taken as a serious drama. Indeed, the characters and the setting lack any real depth; they are, first and foremost, vessels for Wilde’s witticisms lampooning the shallow and roots-obsessed society in which he lived. However, this is not to the plays detriment – the audience is treated to some of the most sparkling verbal wit ever seen. Whether luxuriating in paradox or simply in the ridiculousness created by the plot that Wilde has set in motion, the play is at its best when it is portraying supposedly serious things in an extremely trivial matter. However, this seeming piece of fluff is enormously influential and is actually a destructive critique of the social mores of the times. The emphasis that is put in the play on surfacesnames, where and how people were brought up, the way that they dressbelies a yearning for something which is more substantial. Wilde can be credited, by producing a piece of polished decadence, with contributing to the destruction of a class-based, surface-obsessed society. Wildes play seems to say, look beneath the surface, try and find the real people stifled beneath social norms. Brilliant, inventive, witty andwhen performedabsolutely hilarious, Wildes The Importance of Being Earnest, is a landmark in the history of Western theater, and probably that writer’s greatest achievement.

Criminology Theory Analysis Essay Example | Topics and Well Written Essays - 1000 words
Criminology Theory Analysis - Essay Example Merton, then, explains how people cope with social norms, goals, standards and means of achieving the prescribed goals. When people are able to conform with the legitimate means of achieving the prescribed goals, they conform with the social norms. In an anomic society, people cope through different means. There are ritualists, those who conform with the legitimate means, conforming to social norms but not expecting to achieve the prescribed goals. When people cannot achieve the prescribed goals through legitimate means, they tend to find other ways, resorting to illegitimate means of achieving the goals. This creates deviance and individuals begin to adapt using rebellion, innovation or retreatism. Individual’s choice of adaptation depends on how they view the prescribed goals and means in achieving it. It depends on their willingness to conform or reject the standards set by the society. Sex work or prostitution can be legitimate or illegitimate depending on the set of values and norms of the society. The exchange of sex for money or material possessions equivalent to the service given can be viewed in different perspectives. A society that views it as legitimate will have no problem since people conform to the social standards of working to get economically successful, one the ultimate prescribed goals of most societies. If prostitution is viewed as illegal in the society, then, it becomes a deviant behavior. The standards, norms and values of the society are created and developed through the shared meanings of the majority or the entire society. These socially accepted standards, norms and values becomes the guiding principle of the individual’s behavior and lives. This becomes the basis of their means in achieving the prescribed goals of their societies. Economic success has been one of the measures of being successful as an individual. This can be classified as a prescribed goal by the society, as it creates personal and economical

Accouting - Speech or Presentation Example The formula to calculate dividend yield ratio is dividends per share divided by market price per share. Dividend yield ratio = $1.50 / $60 = 2.5%. d) The price-earnings ratio is an index that shows whether a stock is relatively cheap or expensive in relation to its earnings. The formula to calculate the price-earnings ratio is market price per share / EPS. Price-earnings ratio = 60 / 7.8 = 7.69. The book value per share is lower than the market value per share by $20. This figure does not necessarily reflect that the stocks of the company are selling at a bargain price. The book value per share reflects the amount that would be distributed to investors if all assets were sold at their balance sheet values after paying off the creditors. a) The current ratio is calculated dividing current assets by current debt. Current ratio = 1,120,000 / 600,000 = 1.87. The current ratio shows the ability of a company to pay off its current debt. A general rule for the current ratio is that if the ratio is above 1.0 it is good. The company is in a good position to pay off its current debt. The current ratio of the firm is below the industry average of 2.1. b) The quick acid ratio is another solvency metric. It is calculated similarly to current ratio with the exception that inventory is deducted from the numerator. Quick acid ratio = (1,120,000 – 610,000) / 600000 = 0.85. The quick acid ratio of the company is below the industry average of 1.2. e) The debt to equity ratio is a measure of the amount of assets being provided by creditors for each dollar of assets being provided by the stockholders (Garrison, et. al.). The ratio is calculated by the following formula: total liabilities / total equity. The purpose of the ratio analysis performed was to determine whether Stephens Company qualifies for a $500,000 loan. The broad profitability of the company is a little lower than the
Discussion problem for legal claim Article Example | Topics and Well Written Essays - 250 words
Discussion problem for legal claim - Article Example The school custodian is also to be sued of warping the school rules and regulations and accepting the bribe promise. Accepting the bribe promise meant that he was not much concerned of the aftermath of such an action but so long as he or she achieved got the promise. The school principal in this case was to be sued of negligence. He actually new what was going on though was not much concerned as he wanted his school to win the competition. In these cases, each and every defendant would come up with their own statements just to evade the case. The school principal in this case would claim that he did have an idea what was going on as he was not informed of such an action. This is possible because the custodian and the head coach assumed that the principal knew nothing and was therefore green about the issue. The custodian in this case would also claim that the head coach bribed him while the head coach would deny and post a claim of negligence on the side of the school custodian for leaving the room open. Though the claims are there for the defensive purposes, they are all involved in this case and are to be held responsible. Not to forget is that Terry was also wrong as he went against the instructions they were given by the head coach though not recognized by the

Healthcare project management Essay Example | Topics and Well Written Essays - 2000 words
Healthcare project management - Essay Example includes a plan of the Hospital will include working with the community in developing and maintaining a project that will decrease the numbers of teens presently using marijuana. The outcomes of the project will include a decrease in the total number of students using marijuana and a decrease in the amount of violence in school. This will be measured by the overall numbers as captured by the school. The health department will supply general community outcomes data while data retrieved from the school will complete other aspects of the data. The scope of the project will begin with the community that is presently served by the South Brisbane Community Hospital. This will be done through awareness and through accessibility of present programs as well as providing workshops for both teens and their parents in a collaborative effort between the school, health department, and the hospital. When data shows improvement, the program will be extended to the country level and then the state level as appropriate. The objectives of this program will be to provide education and information on the dangers of marijuana use in high school and the violence that it creates in an effort to help these students better understand. It will also provide essential information for parents and other caregivers in understanding the ramifications of use. This project is measureable. Success will be shown by a decrease in the numbers of students using marijuana and in the amount of violent occasions that take place in school. This data will kept monthly, analyzed every six months and reported yearly. The local community has an increasing problem with the use of marijuana by teens in the area. Studies show that violence in schools is directly related to the amount of illicit drug use that happens at the local schools (Cohen, Lowry, and Modzeleski, 2009). There is a lack of awareness of the dangers of marijuana use and presently, it is difficult to access information that is being given

Purely Competitive Vs Monopoly in two industries Essay Example for Free
Purely Competitive Vs Monopoly in two industries Essay There are two types of industry wherein a businessman could put his cash on: the monopoly and the purely competitive one. This paper explains the case if a worker in a purely competitive industry and a worker in a monopoly industry returns the same or different marginal revenues on the case that the labor market is purely competitive if they have exactly the same marginal product and their product price is the same. Citing the difference between the types of industry will give us an idea to decide with the case given: Differences between Monopoly and Competition (Hartcourt, 2001) Monopoly  The only producer of the goods The demand curve has a downward slope. â€Å" price maker† Lowers the price to increase sales Competition Competes with companies producing the same products The demand curve is horizontal â€Å"price taker†Sells as much or as little at same price. Marginal revenue is described as the extra revenue that an excess product unit will bring to the industry (Schenk, 2002). Whether a worker is in either a purely competitive or a monopoly, and considering the case stated on the previous paragraph, both workers will return the same marginal product return since their marginal products, as well as the product price are the same. MPR = total revenue/quantity of units sold ( Hartcourt, 2001) If we think not that critically, the prices introduced by the workers from different industries are the same, and the number of units to be sold is also the same, the MPR will be the same. But from the bulleted descriptions of monopoly and competitive industry, the demands are different. For the monopoly, the demand is sloping downward; but form the competitive, the demand is the same as represented by the horizontal curve. For a competitive industry, the MPR is directly proportional to the price, but in a monopoly industry, the demand is decreasing, so the MPR will decrease also, leaving us the conclusion that the MPR’s for the two are different.

Constructability And The Safe Design Principles Construction Essay
Constructability And The Safe Design Principles Construction Essay Constructability Safe Design Principles serves as a preliminary process to provide Parsons Engineers, and the Construction Management Engineers an easy methodology to identify constructability issues hazards that are likely to arise in the erection process and provide reasonable design features to preclude potential peril in the design phase of the Arabian Canal Project Infrastructure. The process provides practical information to Parsons Design Engineers to assist them in identifying constructability issues hazards of equipment and systems used in the construction of the Arabian Canal Project Infrastructure. It offers practical principles that can be applied to control additional constructability issues hazards found on the building site, in structural components, and from materials, processes, and procedures employed during construction and maintenance. This process is for developing the skills of Parsons Engineers to control many kinds of constructability issues hazards at th e time of design or before work begins on site to achieve optimal constructability and safety throughout the construction process and the life cycle of the Arabian Canal Project Infrastructure. International studies have concluded that approximately sixty (60%) percent of all fatal accidents in construction arise from faulty design or insufficient planning. While the exact percentage remains the subject of debate and discussion, a number of this magnitude challenges those who manage the process of design to save lives and money simply by application of improved engineering practices. Such perspective should be a revelation to Parsons Engineers who are accustomed to view the majority of accidents in the construction industry as attributable to the routine chaos of the construction site. To do so would focus more on prevention than ever before. The objective of this process is to develop and/or expand engineering principles of constructability safer design for construction and the life cycle of the Arabian Canal Project Infrastructure. To accomplish this task we shall draw from four pioneering approaches to constructability safer design. These approaches which form the corn erstone of modern system safety engineering principles are the following: Eliminate the hazard if possible, or; Provide guarding to prevent contact with the hazard, and; Provide safety factors to minimize the hazard, and; Provide redundancy to confine the hazard. All four applications necessarily involve highly focused Parsons Engineers. Though these principles have been extended, there is still no methodology to simplify these principles and incorporate them into a simple methodology. Start of the process develops methodology for identifying constructability issues hazards then matching the issue or hazard with design features and/or safety appliances for the prevention of the hazard. This will highlight the role of the Parsons Engineer as a designer. When the Parsons Engineer places emphasis on constructability hazard prevention by designing out the hazards inherent to construction processes, products, or facilities, the circumstances that produce construction interferences injuries will be drastically reduced. The second section provides the Parsons Engineer with a system for identifying hazards with an insight into the nature of hazards and guidance that categorizes the hazards into manageable groups. Specific identification of the different types of hazards in the design stage streamlines the hazard elimination process by providing guidelines to determine general control measures. This process will provide Parsons Engineers with easy principles of system safety adaptable to design and constructability that ensure for the elimination and control of hazards. Then it will provide a method to quantify the ability of design improvements to prevent injury, death, and damage in terms of reliability. For instance, before a construction project even begins, the construction manager faces the potential constructability issues and hazards of faulty design by the architect, defective design of the equipment that must be used, and hazards within the construction site or property. To successfully control constructability issues and hazards during the project, these obstacles and hazards must be identified and addressed during design and planning stages. This process distills system safety methodology into five principles that focus on hazard identification, isolation, and control through constructability, innovative technology and applied science. A design matrix provides a check sheet to ensure potential loss exposures have been identified and controlled before the design has left the drafting room. Practical application of this method eliminates or controls potential constructability issues and hazards. In a world of exponential increases in technology, Parsons Engineers have new and exciting options available to them. Parsons Engineers who can think outside the box will find many opportunities to re-engineer products using new materials and informational devices in a way that produces a constructible and safer product or process. Constructability Safety In-Design Compliance Procedure Engineering Department Procedure Constructability Safety In-Design Compliance Program Parsons Constructability Safety-in-Design (CSID) program is an ongoing implementation and confirmation effort relating to a projects safety requirements. Parsons CSID approach evaluates and resolves hazard analysis relating to the mitigation of personnel and public hazards in a facilitys construction and operation, adherence to code requirements, and beneficial safe design practices. The Parsons CSID process begins with implementing the Constructability Safety-In-Design Compliance Procedure and supported by the Parsons Constructability Safety In Design Process Guide. The Parsons comprehensive Constructability Design for Safety Training Process ensures the project staff fully understands the CSID processes and continually works to ensure complete implementation. The CSID review committee will be tasked with completing the Constructability reviews. The Parsons Constructability review is a review of the plans and specifications to check for build ability and bid ability. When reviewing for build ability, Parsons checks for the completeness of the drawings. This includes a cross-check between the various disciplines (electrical, mechanical, architectural, structural, plumbing, civil, and landscaping, etc.) to coordinate pipeline sizes locations, power capacities, road and bridge layout and sizing, and other major components that are essential to build the infrastructure. Additionally, there may be dimensional errors in calculating radius building plots that impact structural steel, site concrete, light bollards, and landscape. Critical dimensions are reviewed to prevent building delays, bidding errors and to ensure the complete project is capable of being under written for insurability. When checking for bid ability, Parsons Constructability R eview Team performs an extensive review of details, notes, sections, elevations, site plans and specifications. As in any contract, the best contract is without ambiguity, error, conflict, and leaves little to interpretation. This review crosschecks the use of detail references and confirms consistent use of building finishes to specifications and other plan details. The work product of the review is a list of comments and a marked-up set of the plans and specifications to be reviewed by the project stake holders. The list of comments is created using the Parsons Constructability Assessment Register so the list can be modified and prioritized by other team members. (It also serves as a checklist to confirm the incorporation of the comments to the documents before going to bid.) A standard procedure to mark-up the drawings with changes is established. For example, green pen will be used to highlight question areas, orange pen will be used if the question is answered as the review continues, blue pen will be used to make corrections, and yellow pen to verify the information was input into the Constructability Assessment Register. Using this standard mark-up policy, the constructability team can clearly show all stake holders the process of how each comment was generated. Additionally, the incorporation of a change is easier to compare the marked-up sheet to the existing design. After the plans and specifications have been marked-up, each comment will be input into the Parsons Initial Hazard Evaluation Register. The process of inputting the information is not just a clerical process, but also a final pass of the plans and specifications. Often additional comments are generated or questions are answered. Once the comments are inputted, the Parsons Constructability Review Team will prepare a narrative explaining the format of the comments and the general outcome of the review. The constructability report (the narratives and comments) will be forwarded to the stakeholders and a meeting scheduled to review the comments. The opportunities to create safer workplaces are most cost effective when captured in the earliest phases of the lifecycle of designed products or processes. The most effective risk control measure eliminating the hazard is often cheaper and more practical to achieve at the design or planning stage, rather than making changes later in the lifecycle when the hazards become real risks to clients, users, employees and businesses. The constructability review will ensure the completed project is insurable, reduce bidders questions, increase the likelihood of competitive bids, reduce RFIs, and change orders and delays during the bid and construction process. It is much easier and less costly to make the changes to the plans and specifications prior to bid, rather than during construction. A constructible safe design approach results in many benefits, including: Prevention of injury and disease, Improved use ability of products, systems and facilities, Improved productivity reduced costs, Better prediction and management of production and operational costs over the lifecycle of a product, Compliance with legislation, Innovation, in that constructible safe design demands new thinking Reducing over all project Increase construction practicality, Eliminates errors and ensures project schedule completion in a timely manner Provides the owner and all stakeholders to have the opportunity to ensure the design is fully acceptable to their standards and expectations Address the life cycle environmental impacts and improves the over all preservation of resources Reduces the life cycle expenses associated with operations and maintenance The lifecycle of a product is a key concept of sustainable and constructible safe design that provides a framework for eliminating the hazards and improving the constructability at the design stage and/or controlling the risk as the infrastructure is: constructed, installed, commissioned, used or operated, maintained, repaired, modified, de-commissioned, demolished and/or dismantled, and disposed of or recycled. The Parsons CSID is a tool to assist designers, engineers, constructors, clients and other key stakeholders to come together to reduce construction, maintenance, repair and demolition safety risks associated with design. Parsons CSID recognizes that a design involves key considerations such as operability, aesthetics and economics with the elements of safety. It also acknowledges that a design process may be determined by many different stakeholders and/or influences. The CSID methodology aims to involve these elements and influences. By proactively considering construction, maintenance, repair and demolition issues, the CSID framework should not only help reduce the number of construction industry incidents, but also assist in improving constructability and reducing the life cycle costs associated with building the infrastructure design project. There is a balance of responsibilities between a designer, a constructor and other relevant stakeholders, such as clients or specialist consultants. It is important that all participants highlight unusual safety risks associated with a design and required construction. As outlined in the Parsons CSID process all those involved should: identify the hazards presented by potential design solutions and consider the risks these hazards will generate for construction workers and others who may be affected by the construction work (e.g. members of the public); include health and safety considerations amongst the design options so that they can avoid the hazards, reduce their impact or introduce control measures to protect those at risk where it is re a s o n a b l y practicable; forewarn the contractor of the residual hazards that have been identified within the design and will need to be managed during the construction work. Eliminating the hazard is the first risk control that should obviously be considered. If the hazard cannot be eliminated (for example eliminating risks associated with maintenance by using aluminum/stainless steel, which requires no regular painting), risk can be minimized by using a series of steps known as the hierarchy of risk control. Including: substituting the system of work or plant with something safer (e.g. pre-assembled equipment at ground level rather than height); modifying the system of work or plant to make it safer (e.g. ensure attachment points for lifting, window cleaning, safety lines, etc.); isolating the hazard (e.g. introduce restricted areas); introducing engineering controls (e.g. prevent falls from buildings during construction/maintenance by increasing wall/edge height). Only when the above constructible and risk control options have been exhausted should consideration (and more importantly reliance) be given to personal protective equipment (e.g. safety harnesses) or adopting administrative controls such as hazard warning signs. Design is the process of considering options. In developing and understanding these options, there is also the ability to improve safety and reduce costs. For example, the costs associated with assembling large scale scaffolding may far exceed the costs associated with alternate design and/or construction materials. Similarly, an emphasis placed on achieving a design that would be safe and efficient to erect, rather than the traditional approach of minimizing steel tonnage, did result in lower project costs. Essentially, given the opportunity to consider the design in a formal and systematic way, a smarter design results and a smarter design invariably leads to a safer design. The following subjects are included in this program: Personnel life safety Safe facility startup Safe facility shutdown Intrinsically safe designs Structural integrity (e.g., seismic, wind, safe loading, equipment support, etc.) Considerations for operating a facility safely Parsons defines project safety requirements as internal or external (Employer) specification, government code, manual, policy, standard, and safe practice that pertains to providing safe and healthful facilities for personnel. The Standard Industry Codes and Standards (or publishers of basic codes and standards), which pertain to safe design practices, will be utilized by the Parsons Design team. The project design team will also include requirements of the Development project objectives and goals, the requirements of Dubai Municipality and its agencies, and other specific Employer requirements or best practices. The Project Manager and Design Manager will be responsible for coordinating and confirming the special constructability and safety requirements for the design elements for the project work. The Project Manager and Design Manager together with the QA/QC manager will verify the appropriate reviews have been performed related to Constructability Safety In Design. The Design Manager will be responsible for establishing the Employer requirements checklists, which include safety-related industry codes/and standards and local/city code requirements. The Design Manager will also direct and coordinate the work of engineers and designers assigned to the project accomplish the Constructability Safety In Design objectives and requirements. Purpose This procedure describes Engineering Department policy for application of the Constructability Safety-In-Design (CSID) Compliance Program. Engineering/design practices and principles contained in this document are intended generally to be applied to all types of facilities during each projects planning and design phase. Constructible Safe design practices rely on the correct use of current basic code requirements, existing design standards, client requirements, and any other known safety considerations that assist in safeguarding against unsafe conditions and help manage unsafe materials and hazardous acts causing illness or bodily harm to workers. Enhances building information modeling and enables design success related to sustainability, security, design-build, risk management, hazard mitigation, insurability and performance-based design. Promotes team building among client, designer and contractor, emphasizing the success of the project instead of the success of the individual, thereby minimizing the commoditization of engineering. Provides ongoing feedback from clients, users, and contractors to the design team, eliminating scope surprises. Reduces total project costs and engineering scope creep, improving profitability. Involves construction expertise in the design phase, identifying field issues and avoiding obstacles, unnecessary construction costs, and lawsuits. Improves the quality of construction documents, minimizing change orders and subsequent post-construction claims. Improves the quality of the next design, incorporating feedback from the field. Figure : Constructability Logic Diagram Definitions Safety As a noun safety shall be understood to mean the condition of being safe from (or causing) harm, injury, or loss. As a verb safety shall be understood to mean protection against failure, breakage, or accident. Constructability Safety In-Design Program Parsons CSID compliance program is an ongoing implementation and confirmation effort relating to a projects constructability safety requirements. Also included are hazard analysis resolutions relating to the mitigation of personnel hazards in a facilitys operation, adherence to code requirements, and safe design practices beneficial to personnel. The following subjects are included in this program. Personnel life safety Safe facility startup Safe facility shutdown Intrinsically safe designs Structural integrity (e.g., seismic, wind, safe loading, equipment support, etc.) Considerations for operating a facility safely Owner/operation procedure supplement Operating sufficiency/redundancy Economic design Ease of maintenance Environmental compliance Construction safety Failure analysis (except for life safety systems) Supplier product/safety responsibilities Safety and Personnel Hazards Typical safety and personnel hazards in operating facilities include, but are not limited to: Fires Explosions Falls Tripping and clearance deficiencies Structural degradation and improperly supported elements Electrical shock Chemical burns and fumes Suffocation Excessive sound levels Use of, and/or exposure to, toxic construction materials (e.g., urethane and asbestos) Toxic materials handling Potable water contamination (e.g., sanitary sewer/process sewer) Radiation nuclear Magnetic fields Use of microwaves Inadequate lighting (eyestrain and darkness) Ergonomic deficiencies (e.g., carpal tunnel syndrome and muscular strain) Materials handling (e.g., overheads, conveyors) Moving machinery parts (e.g. guards, over speed, vibration, emergency stop/lockout) Hazardous spills Moving objects (obstructed vision) Inadequacy of alarms/communication systems Unanticipated structural loading (e.g. large number of people on platforms) Hazard Analysis A hazard analysis is generally intended to identify and examine hazards during all phases of design, construction, and operations, as applicable to the requirements of each project. This analysis includes hazards and operability (HAZOP) studies, what-if evaluations, failure mode and effects analyses (FMEA), and event-tree and fault-tree analyses. Hazard analysis is not a function of the Engineering Department but is handled by others. On some projects, hazard analysis is performed by the client. Constructability Safety Systems Typical Constructability safety systems include, but are not limited to, the following three categories. Monitoring Systems Fire and smoke detection alarms Toxic material sensors and alarms Critical sampling systems Constructability Safety Device Systems (permanent and in-place) Safe electrical voltages near personnel Explosive protection Protective material coverings Adequate exiting and door hardware Shielding Fall protection Ladder clearances and cages Stair handrails, platform handrails, and toe plates Operability of valves Machinery guards Safety color coding Signage Emergency stop switches Equipment-keyed lockout switches Emergency Protection Systems (activated by an incident) Eyewash and safety-shower stations Emergency/exit lighting Emergency communications Emergency alarms Fire sprinklers Emergency exit facilitation devices (e.g., slides) Electrical circuit protection (e.g., circuit breakers and fuses) Constructability Safety In-Design Process Guide Constructability and Safe Design Concepts Specific aims and goals in the beginning of this process address the theories and methodology of constructability, hazard identification and the development of design features to eliminate the obstacles and hazard and/or minimize the probability of constructability and injury or damage failure mode. Constructability and safety engineering should include the process of systematically controlling constructability issues and hazards through design considerations or with the use of safety appliances. Principle One: Definition of a Hazard and Constructability To begin to address constructability safer design principles in construction and the life of the Arabian Canal Project Infrastructure, one must first understand the actual nature of constructability and hazards. A specific definition of constructability and hazards provides the Parsons Engineer with a basis to develop a methodology for planning and evaluating the construction and the life cycle of the Arabian Canal Project Infrastructure process for constructability and safety ensuring for design of constructible, safe systems and equipment. The undertaking of such construction design principles leads to safe operation of a completed facility. What a hazard is in practical terms: Definition: A hazard is an unsafe physical condition that is always in one of three modes- Dormant/Latent (unable to cause harm), Armed (can cause harm), Active (causing injury, death, and/or damage by releasing unwanted energy, substances, biological agents, and or defective computations from computer software. In greater detail, a dormant/latent hazard is a design defect that is susceptible to a failure mode. Foreseeable misuse should also be considered (a kitchen chair may be used to stand on to reach upper cabinets and needs to be sturdy enough to prevent collapse.) The armed hazard is created by a change of circumstances and is ready to cause harm (the chair may have a big knot on one leg). The active hazard is an armed hazard triggered into action (when the chair is stepped on the knot cannot support the additional load and the chair leg collapses, causing a fall.) Definition: Constructability is the optimum use of construction knowledge and experience in planning, design, and procurement and field operations to achieve the overall project objectives. The basis of constructability concept is that experienced construction personnel need to be involved with the project from the earliest stages to ensure that the construction focus and their experience can properly influence the owners, planners, and designers, as well as material suppliers. This does not necessarily mean that the design or project objectives should be changed to meet constructability only from a cost standpoint. Constructability should be used as a design consideration, so that optimum results provide the best of both worlds. Parsons approach to the Arabian Canal Project Infrastructure Design will emphasize constructability with various characteristics and be implemented as design progresses. Parsons Design and construction managers are committed to the cost effectiveness of the whole project. They recognize the high cost influence of early project decisions. Parsons managers use constructability as a major tool in meeting project objectives concerning quality, cost and schedules. Parsons managers bring construction aboard early. This means using experienced personnel who have a full understanding of how a project is planned and built. Parsons Designers are receptive to improving constructability. They think constructability, request construction input freely, and evaluate that input objectively. Early constructability efforts result in a significant payback to the project. Industry research has cited cost reductions of between 6 and 23 percent, benefit/cost ratios of up to 10:1, and large schedule reductions. The intangible benefits are as important as the quantitative benefits and must be recognized accordingly. These include; more accurate schedules, increased productivity, improved sequence of construction, enhanced quality, decreased maintenance, and a safer job. Parsons will provide input to the planning and design from the standpoint of project intent, constructability, safety, operation and maintenance. This will be accomplished through field reconnaissance with designers and reviews of design documents at various stages of development. Obtaining feedback from maintenance personnel at this point is very important, since they ultimately live with the finished product and are aware of previous construction deficiencies. The reviews will be scheduled during both the Conceptual Development and the Design phases. Principle Two: Establish a Standard of Constructability and Safe Design Constructability and Safety must be converted into a powerful design priority and overriding planning concern to be effective. It must rely primarily on the physical elimination of each construction obstacle and hazard, rather than upon human performance, which is variable and cannot be programmed, to avoid the obstacle or hazard. Through the evaluation and close scrutiny of each activity, task or phase of the construction process we are able to identify possible failure modes to identify hazardous conditions. A well-known tenet of safety engineering states Any hazard that has the potential for serious injury or death is always unreasonable and always unacceptable if reasonable design features and/or the use of safety appliances are available to prevent the hazard. The key to successful safety engineering is to identify and design out as many hazards as possible. When this tenet is applied as a design standard, it becomes a routine expectation to design out hazards, thus changing a dangerous facility, product or service into a safer one. The identification of construction obstacles and hazards is the basic building block to ensure for a safe construction and operation during the life cycle of the Arabian Canal Project Infrastructure. Often the same construction obstacle or hazard that has been causing injury, damage, or down time surfaces uncontrolled on multiple occasions. Falling loads due to two blocking were recurring hazards on construction sites for many years. This trend stopped when anti-two blocking devices were installed by manufacturers on all new cranes and retrofitted onto most cranes in the field. By relying on our past experiences, remembering backwards is not all that difficult to begin to control construction obstacles and hazards. Principle Three: Categorizing the Hazard Hazard Source The third step in hazard identification is to determine which of the following seven categories contains the source of the hazard: Hazard Source Natural Environment Structural/Mechanical Electrical Chemical Radiant Energy Biological Automated Systems Artificial Intelligence Now the hazard can be binned into a convenient box or boxes. Each of these boxes contains just a few examples that serve as a starting point for the Parsons Engineer to begin to focus on the nature of the hazard. These topics are meant to be a starting point to develop additional listings for failure modes. It is important to note that hazard categories may overlap or fall into one or more groups. It is common to encounter a hazard that contains simultaneous natural, mechanical, and chemical properties. In these cases, specific hazards should be broken down into as many individual properties as possible. Natural Environment The first box is our natural environment. The laws of gravity cannot be repealed, nor can the weather be programmed or the ocean drained. The following are a few hazard source possibilities that the Parsons Engineer must contend with in the natural environment. Natural Environment Gravity Falls same level Fall from elevation Falling objects Impact Acceleration Slopes Upset Rollover Sliding Unstable surfaces Water Floating Sinking Drowning Atmosphere Change in Altitude Humidity Wind Visibility (fog, etc.) Dust Temperature Limitations on Human Performance Structural/Mechanical Hazards The second box delineates mechanical hazards. As engineers we must consider their mechanical advantage, but also their possible danger.

Sony Corporation Executive Summary :: Sony Business Marketing Essays
Sony Corporation Executive Summary Sony's current financial difficulties are tied into its corporate culture which were stated over 30 years ago. With such a large multinational corporation, greater planning and more use of strategies should be pursued. Sony could start with the implementation of a new mission statement, with profit and benefits of the company tied more closely to everyday operations. Internally, the four forces, the management, the designers, the production and the marketing should achieve better communication and cooperation. Alliance and cooperation between competitors should also be actively sort after in order to create standards in new fields. Sony should aim at being the leader instead of being the maverick. As for cost cutting, Sony should seriously consider setting up operations in other Asian countries in order to take advantage of the cheap labour and the budding markets. Finally, diversification, instead of pursuing the fast changing and easily imitated consumer goods market, Sony should use its technological know-how for high-end business and office equipment. With SWOT analysis and Porter's competitive forces model, we can view that the market is much more competitive with less profit margins and lead-time for product innovation. The conclusion is that change is needed in Sony. However,even with strategirial and structure change, the Sony spirit of innovation should remain intact because that is what made Sony grow and would make it stay strong. Introduction The first thing that comes to peoples minds of the company and products of Sony is its high-technology-filled-with-gadgets electronic goods and innovation. It was also this innovation that make Sony the greatest company that started in post-war Japan. Sony has used its innovation in building markets out of thin air, created a multibillion, multinational electronic empire with products such as the transistor radio, the Trinitron, the Walk-in and the VTR. that changed everyday household lives forever. However, this consumer targeted quest for excellence and constant innovation instead of targeting mainly at profit also has a lot to do with current crisis Sony is facing - sales and profits are down or are slowing down, capital investment cost and R&D are climbing, competitors are moving in with copycats, the battle between VHS and Beta and the search for a smash hit product such as the Trinitron or the Walk-in. This volatility and emphasis (or gambling) on new products instead of concentrating on profit and loss statements have always been a part of Sony since its beginning days. For each successful product (i.e. transistor radio and Trinitron), R&D cost often ran so high that the they pushed the firm to the verge of bankruptcy. This can also be seen through the eyes of the investor in which although sales have increased tremendously

David Mccullough’s “1776†Essay
David McCullough, who has won Pulitzer Prize and National Book Awards two times impresses in his book†1776 â€Å" that the year 1776 is one of the most significant years in annals of U. S. A . McCullough segregates his book not by key military skirmishes but by negligible incidents with major consequences on those skirmishes. McCullough in his book â€Å"1776†lucidly explains the triumphant American siege of Boston in 1775, the catastrophic defense of New York City against irresistible British troops in the late summer of 1776, the Continental Army’s close encounter with dissolution and failure and its excellent dead-of-winter success over the Hessians and the British at Princeton and Trenton as 1776 gave way to 1777. According to McCullough, General Washington was not without flaws but as a military inexpert who was out-generaled by his British adversaries. By demonstrating the intensity to which American fortune had descended by mid-November 1776, McCullough lauds the triumph in Trenton and illustrates that how American heroism is yet again demonstrated. McCullough restricts himself to events that occurred in a single calendar year and a little more. Further, he zeros in on a single person –General Washington. McCullough prose is stylish, sturdy and has a novelist style of structure and pacing. The choice of year 1776 is wise one as it was the year of roller-coaster ride in terms of American military triumphs. â€Å"1776†began on a high note when General Henry Knox, taking the benefit of severe winter weather, employed sledges and barges to transport about sixty tons of cannons and mortars down from Fort Ticonderoga in northern New York and across snow heaped Massachusetts countryside. 1 Negotiating anxiously in the night, General Washington troops successfully placed the artillery atop Dorchester Heights, facing Boston Harbor, in early March 1776. Though, the city was under the control of British, they were now openly exposed and the British had no other choice but to withdraw. The three key chapters of book are categorized as follows; ? The Siege ? Fateful Summer ? The Long Retreat In the first chapter â€Å"The Siege†, McCullough narrate the military features of war. It is to be recalled that the title â€Å"The Siege†was coined after the fortifications made at Dorchester Heights. In this chapter, McCullough recounted insight to the minds of combatants on each side of the skirmish with excerpts from letters written by soldiers. At that point of time, warriors on each side were under the impression that they had the enough motives to fight but did not realize that it would soon transform. Howe, the general on the British side was a man of action and had not any patience to wait and wanted to settle his score with American troop instantly. However, General Washington was most concerned about the inexperience and lack of knowledge of his warriors. Further, adding fuel to the fire, there was shortage of firearms and ammunitions on American side which had made General Washington to worry about. At this juncture, McCullough recalled the exact words used by General Washington when he narrated this precarious situation to his brother through a letter. â€Å"We had fewer bullets than riffles and not adequate riffles for every soldier and not enough soldiers to succeed into the war. †The shortage of firearms for rebels was such that General Washington had issued precondition to those who wanted to join him to fight against British to bring firearms with them from the farm. This scenario aptly illustrates how American side was in wobbly condition as regards to firearms and ammunition as compared to the mighty British army. Further, in this Chapter, McCullough describes the information exchanged by General Washington with his wife through letters which detailed the problems and pitfalls faced by rebels and how American army was handicapped and devised its strategy against the mighty British. However, as per McCullough, General Washington was highly diplomatic as he never revealed how frantic the scenario was to American soldiers at that juncture. In one another letter to his brother, General Washington was of the opinion that he wanted to be an enlisted warrior rather than holding the position of General and always concerned for the soldier’s morality. At the conclusion of the first chapter, McCullough narrates that fortunately General Knox arrived in Dorchester with much wanted cannons and due to this, the future looked very dazzling for the American soldiers. The second chapter has been named as â€Å"Fateful Summer†since General Washington was under impression that the destiny of unborn millions now reckon on his success. General Washington cautioned his troop that failure was not an option and at any cost, they must achieve success. Major portion of this chapter devotes to memoirs of General John Sullivan, Major Joseph Reed and General Rufus Putnam. McCullough recalls that there is absence of unity among colonies at that juncture. Since, majority of the generals were from South, they had feeling that they were superior to generals hailing from North. McCullough reveals this through the conversation that had occurred between General Washington and General Graydon as they vouched that â€Å"Yankees were despondently organized†and did not visualize that the northern regiments would be able to safeguard their position in battle. However, Southern leadership found that they had a misconception on the strength of the northern regiments when they vigorously wrestled and won in Bunker Hill and in Lexington. McCullough illustrates that majority of men who has joined the regiment at that juncture were from northern colonies. McCullough also refers General Washington’s quote that he did not envisage any concern with Negroes who have then freed from their slavery but was not especially consonant with them in his status and rank. McCullough also portraits young soldiers who have joined the regiment did not have any discipline as no proper training were imparted to these young new recruits. Further, these young soldiers were also affected by sexually transmitted diseases when they had relationship with prostitutes who roamed the New York City at that time and there was also shortage of medicine to cure them. According Washington estimate, he lost more 10,000 soldiers due to prevalence of small box and venereal disease. This chapter ends with note that though American suffered a big defeat, however they were united in their cause and had plans to flee away to New York to settle their scores in another day. The third and final chapter is named as â€Å"Fortune Frowns†. In this chapter, McCullough explains how Washington informed their defeat to Congress. McCullough uses most of the letters written by Washington to his wife in this chapter to narrate the incidents. However , Washington never exchange military or warfare strategies with his wife this time as in the past but gave instruction about how interior had to be organized in his residence. With defeat in the Battles of Long Island and Brooklyn, Washington, his troops and the nation were witnessing very hard time. In his letter to Governor Trumbull which was written on December 14, 1776, Washington mentioned that he wanted to assume risk to any extent and all that he needed was a bit of luck. Washington also unraveled in that letter that his strategy was to cross the Delaware during the dark and wage an attack on Trenton engulfing from three sides. This time there was excellent cooperation among the commanding generals. Washington strategy worked well and attack after crossing Delaware during dark was a remarkable triumph for Washington. McCullough in his concluding part of the book made a high note about the success in Trenton battle. McCullough in his book â€Å"1776†narrates several inspirational speeches delivered by General Washington to his soldiers from his horse back. It is to be observed that General Washington’s greatest talent was his capability to inspire even the most timid soldier to become courageous enough to wrestle. Success in Trenton has proved American heroism once again. McCullough wish to remind us that Americans have to value their ancestor’s grand sacrifice and if Americans fail to recognize the same, freedom may slip away from them. The moral of the book is that sole purpose to remind the battle against British in the year 1776 is to conserve the good deeds accomplished for Americans in the past so that American can prepare for the tasks and trials which still lie ahead. Hence, this is history as a structure of national rearmament that is why it harmonizes so nicely with the embattled nation temper.

Insect: Mosquitoes
Chapter I Introduction Background of the Study Mosquitoes nowadays are a problem for us humans. Mosquitoes are attracted by skin odors and the carbon dioxide in our breath. With our climate, it is easy for us Filipinos to get attracted by mosquitoes simply because we are sweating a lot. Because of mosquito bites, we can easily get diseases like West Nile Virus, the West Nile virus is contracted when a mosquito bites a human or animal. This virus can cause fever, headache, nausea, vomiting and rash in its early stages and can lead to paralysis. Dengue Fever, a contracted type of mosquito bite mainly during the day.Especially dangerous for children, dengue fever is found primarily in the tropics. It resembles viral flu and can be fatal. Malaria, also found primarily in tropical regions, mosquitoes carrying malaria bite during the night. Symptoms of this disease include fever, chills, headache, malaise and muscle ache. And Yellow Fever, Mostly found in South America and Africa, yellow f ever resembles the symptoms of other diseases carried by mosquitoes. In addition to these flu-like symptoms, yellow fever can also cause backache and jaundice and can be fatal.The menace posted by mosquito bites have surged so much that mosquito control measurements are almost crucial to keep ourselves from contracting serious illnesses like the malaria or the West Nile Virus. Mosquito control is more significant than ever before. Infected mosquitoes are the main culprit behind the spreading of these diseases and avoiding mosquito bites is the only successful way to remain unhurt. Some Mosquitoes that carry the West Nile virus are often active at dawn and dusk, which makes them less likely to be noticed.Mosquito bites can produce allergic reactions. Itchy red bumps, for instance, are considered allergic reactions to the insect's saliva. More severe reactions include blisters, hives, bruises and intense inflammatory reactions. Our problem that we need to solve is the mosquitoes, beca use it carries the Dengue virus, which we Filipinos are aware of. As of this year, many people have died because of dengue. We want that we can help in our own way is to repel mosquito in our skin so we will not get hurt or get a bite from a mosquito. Statement of the ProblemOur main goal is to create a mosquito repellent that is eco-friendly, yet effective in repelling mosquitoes. Also, compete with the standards of the commercialized repellent. The researchers aim to answer these following questions: 1. Are the organic mosquito repellent sticks better than the commercialized repellents? 2. Is using lemongrass and catnip possible in making effective organic mosquito repellent sticks? 3. Which is more effective? Basing on the number of mosquitoes repelled and killed. (Catnip stick, lemongrass stick, or both combined. ) HypothesisThe organic mosquito repellent sticks can be a substitute to a commercialized repellent, because it is more eco-friendly and maybe less harmful to the body especially the lungs. The researchers think that it is possible to make organic mosquito repellent sticks using lemongrass and catnip, since those two agents are known to be effective ingredients in making mosquito repellents. The researchers believe that the coil with both agents is much more effective, because the effects of both agents combine is much better than just one of the catnip or lemongrass. Definition of Terms . Mosquito-repelling incense -Usually shaped into a stick, and typically made from a dried paste of pyrethrum powder. -In the study, this refers to the product that the researchers are trying to create. 2. Lemongrass -A fragrant tropical grass that yields oil that smells lemony. -This refers to the tall grass used in making the repellent sticks. 3. Catnip -A natural mosquito repellent. -One of the main ingredients of our mosquito repellent sticks. 4. Malaria -Caused by a parasite called Plasmodium, which is transmitted via the bites of infected mosquitoes. In this study, this is the disease that is common in poor countries caused by a parasite 5. Dengue Fever -A contracted type of mosquito bite mainly during the day. Especially dangerous for children, is found primarily in the tropics. -In the study, this is the virus that is widely spreading in the Philippines that we want to prevent. 6. Nepetalactone – It is an organic compound first isolated from the plant catnip. -In the study, it is the main component of catnip that makes mosquitoes be repelled. Significance of the Study The significance of this study aims to help people prevent mosquitoes from staying in homes or schools.The researchers want to help people who get irritated by pesky mosquitoes. The researchers want to help certain people who encounter mosquitoes in their everyday life. 1. General Public a. The masses in general, since everyone needs to be protected from these insects for they are harmful to the body. 2. Campers b. These people like boy scouts and mountaineers like to stay outdoors, such as forests and mountainous areas, where there are a lot of mosquitoes. So the researchers want to help them repel mosquitoes on their camps. 3. Parents c.Parents want to prevent their children from getting bit by mosquitoes making them. Our organic mosquitoes repellent sticks will be a great help to these people 4. The Poor d. These people can’t afford to buy repellents for their homes. This will aid them, because it is easy to make and really affordable even to the poor. Scope and Limitation Our scope of the study is to make effective mosquito repellent sticks, to prevent mosquitoes from invading homes and other places. To lessen the risk of diseases caused by mosquitoes, such as Dengue Fever and Malaria.As a group we can only limit our organic repellent sticks to only prevent mosquitoes, but not to other insects. The researchers only aim to repel mosquitoes, but not to the extent that we would stop their existence. Chapter II Review of related l iterature Mosquito Coil Mosquito coil is mosquito-repelling incense, usually shaped into a spiral, and typically made from a dried paste of pyrethrum powder. The coil is usually held at the center of the spiral, suspending it in the air, or wedged by two pieces of fireproof nettings to allow continuous smoldering.Burning usually begins at the outer end of the spiral and progresses slowly toward the centre of the spiral, producing a mosquito-repellent smoke. A typical mosquito coil can measure around 15 cm in diameter and lasts up to 8 hours. Mosquito coils are widely used in Asia, Africa, and South America. Bad effects Burning mosquito coil (MC) releases various aromatic compounds like benzo pyrenes, benzo-fluoroethane and particulate matters. These chemicals have the potential to produce harmful effects on airways as demonstrated by histopathological changes in the airways of various animal models.It has been estimated that burning one MC over 8 hours produces particulate matter sm oke (as measured as PM2. 5) equivalent to around 100 cigarettes. Particulate matter pollution has been shown to increase airway hyper responsiveness and cause decrements in lung function. Mosquito The mosquitoes are a family of small, midge-like flies: the Culicidae. Although a few species are harmless or even useful to humanity, most are a nuisance because they consume blood from living vertebrates, including humans. The females of many species of mosquitoes are blood eating pests.In feeding on blood, some of them transmit extremely harmful human and livestock diseases, such as malaria. Some authorities argue accordingly that mosquitoes are the most dangerous animals on Earth. Eggs of some mosquitoes float on the water in rafts. Larvae, often called wigglers, have a soft body, a hard head and a breathing tube, or siphon, at the tip of the abdomen. Pupae are shaped like a comma, and are commonly called tumblers. Adults have delicate legs, a long proboscis and one pair of transparent wings Dengue Dengue fever, also known as break bone fever, is an infectious tropical disease caused by the dengue virus.Symptoms include fever, headache, muscle and joint pains, and a characteristic skin rash that is similar to measles. In a small proportion of cases the disease develops into the life-threatening dengue hemorrhagic fever, resulting in bleeding, low levels of blood platelets and blood plasma leakage, or into dengue shock syndrome, where dangerously low blood pressure occurs. Dengue is transmitted by several species of mosquito within the genus Aedes, principally A. aegypti. The virus has four different types; infection with one type usually gives lifelong immunity to that type, but only short-term immunity to the others.Subsequent infection with a different type increases the risk of severe complications. As there is no commercially available vaccine, prevention is sought by reducing the habitat and the number of mosquitoes and limiting exposure to bites. Treatment of acute dengue is supportive, using either oral or intravenous rehydration for mild or moderate disease, and intravenous fluids and blood transfusion for more severe cases. The incidence of dengue fever has increased dramatically since the 1960s, with around 50–100 million people infected yearly.Early descriptions of the condition date from 1779, and its viral cause and the transmission were elucidated in the early 20th century. Dengue has become a global problem since the Second World War and is endemic in more than 110 countries. Apart from eliminating the mosquitoes, work is ongoing on a vaccine, as well as medication targeted directly at the virus Catnip Catnip is a perennial herb and member of the Mint family Labiatae. It is native to Europe ; Asia, however has become naturalised in America ; Canada after being introduced.There are approximately 250 species of Catnip. The active ingredient which causes this is an essential oil called nepetalactone, which can be found in the leaves ; stem of the plant. Other constituents include Acetic Acid, Alpha and beta-nepetalactone, Citral, Nepetalactone, Geraniol, Dipentene, Citronellol, Nerol, Butyric Acid, Valeric Acid and Tannins. Catnip is also known by the following names:  Cataria, Catmint, Catnep, Catrup, Cat's Heal All, Cat’s-play, Cat's Wort, Catswort, Catwort, Chi Hsueh Tsao, Field Balm, Garden Nep, Herba Cataria, Herba Catti, Nebada, Nep.Lemongrass Lemongrass herb is a very popular plant found commonly in India and used for medicinal, food and mosquito and insect repellent products. The lemongrass oils are also used in cosmetics, soaps, perfumes, dyes and odorizes along with thousands of other products. There are many different and related types of lemongrass, all belonging to the grass family, Poaceae. East Indian and West Indian lemon grass are popular names for Cymbopogon flexuous and Cymbopogon citratus. Lemon grass is an evergreen, native to Southeast Asia, India, Myanma r, Thailand, Sri Lanka, and Australia.Another type of lemongrass also used in insect repellents comes from Malaysia. The thin stems and foliage of lemon grass ranges from blue-green to gold, and the flowers are white, cream, or green. Lemongrass grows to around 8 feet in height in some cases with the majority of species tapering off at 4 feet. Lemon grass grows best in full sun and moist soil and cab be propagated by dividing the root clump into sections. Lemon grass leaves can be dried or frozen but require rehydration before use. Lemon grass is very mild, rating only a one on the hotness scale.It is mostly known as a common staple found in Thai, Vietnamese, Cambodian, Indonesian, and Indian cooking. Lemon grass is used in curry, stir fry, soups, and marinades and it can be sauteed, mixed with soy sauce and spices, and used as a marinade. Lemongrass is particularly popular with seafood due to its distinctive lemony aroma and flavor. Effectiveness In a 2004 study presented at the Ca lifornia State Science Fair, a 25-percent lemon grass solution was tested against a commercial 15-percent Deet spray.The lemon grass brew was 51 percent effective in repelling mosquitoes, compared to an effectiveness of 81 percent for the Deet product. The study concluded that lemon grass showed promise as a partial replacement for Deet-based repellents. In a study conducted in 2010 at Maranatha Christian University, researchers compared lemon grass stem extract to citronella oil. Citronella oil proved more effective at repelling mosquitoes than the highest concentration of the lemon grass extract. Both studies reveal that while lemon grass does repel mosquitoes, it does not work as well as other products.Nepetalactone Nepetalactone is a terpene composed of two isoprene units, with a total of ten carbons. Its chemical structure is similar to that of the valepotriates derived from the herb valerian, which is a mild central nervous system sedative (or stimulant to some persons). The molecular formula for nepetalactone is C10H14O2. The first fully characterized methylcyclopentane monoterpenoid. Isolated from the volatile oil of catnip produced by Nepeta cataria Nepetalactone , its cas register number is 21651-62-7.It also can be called Nepetalactone cis-trans-form ; Cyclopenta(c)pyran-1(4aH)-one, 5,6,7,7a-tetrahydro-4,7-dimethyl-, (4aS,7S,7aR)- ; Cyclopenta(c)pyran-1(4aH)-one, 5,6,7,7a-tetrahydro-4,7-dimethyl-, (4aS-(4aalpha,7alpha,7aalpha))- . It is an organic compound first isolated from the plant catnip. Chapter III METHODOLOGY This chapter presents the project’s research design, list of materials and their quantities needed for the research, and the laboratory procedures which are the pre-lab procedure, laboratory proper, and post laboratory. Research Design This study made use of an experimental research design.The experimental and control groups were used in this study. This design is illustrated as follows. Table 3. 1 Set-up| Location| Product Used| Quantity of Mosquitoes| Set-up A| Enclosed room| Catnip Incense Stick| 10 mosquitoes| Set-up B| Enclosed room| Lemongrass Incense Stick| 10 mosquitoes| Set-up C| Enclosed room| Catnip and Lemongrass Incense Stick| 10 mosquitoes| Set-up D| Enclosed room| CommercializedIncense Stick| 10 mosquitoes| Subject of the Study -The researchers used mosquitoes as the subject to the experiment. Ten mosquitoes in each container, with a total of forty mosquitoes (Caught with the mosquito trap).Materials Needed: One (1) – Masher Four (4) – Mosquito traps Three (3) – Incense holders Ten (10) – Incense sticks Two (2) – Catnip Two (2) – Lemon Grass Four (4) – Containers of Mosquitoes One (1) – Commercialized repellent Pre-Lab Procedures: Catnip and Lemon Grass were collected by the researchers. The researchers pulverize the Catnip and Lemon Grass to extract the juices from them. The researchers then put the extracted juices into 3 containers. First with only the catnip, Second with only the lemon grass, lastly with both catnip and lemon grass in the container. Laboratory Proper Procedures:The researchers applied the juices of catnip to three incense sticks and was labeled Set-up A, lemongrass extract juice to the other three incense sticks and labeled Set-up B, and both the lemon grass extract and catnip extract juices to the remaining incense sticks and labeled Set-up C. The commercialized repellent was labeled Set-up D. The researchers applied the extract juices thoroughly by hand or by cotton swabs. The researchers then let the incense sticks rest for about 6 to 10 minutes, to let the extract juices be absorbed by the incense sticks. Post Laboratory Procedures:The researchers put the incense sticks in their respective incense holders in order. The researchers then put sample #1 in an enclosed room beside the mosquito trap. The researchers then lit up the incense sticks and released the first batch of mosqu itoes. The researchers closely observe the experiment. The researchers then waited for the incense sticks to disintegrate (15 to 20 minutes). Then the researchers do the same with the sample #2, sample #3, and to the commercialized repellent. The researchers recorded the results based on how many mosquitoes were repelled and killed.Chapter IV Presentation, Interpretation and Analysis of Data This chapter shows the presentation, interpretation and analysis of data gathered after a thorough investigation. Table 4. 1 Mosquitoes that were effectively repelled Experimental| Quantity(number of sticks)| Mosquitoes Repelled| Time Element (minutes)| Catnip| 3| 4 out of 10| 20| Lemongrass| 3| 3 out of 10| 20| Both Combined| 3| 5 out of 10| 20| The table above shows that the Incense stick with the Catnip effectively repelled 4 mosquitoes and the Incense stick with the Lemongrass only killed 3 out of 10 mosquitoes.On the other hand, the Incense stick with the Catnip and the Lemongrass combined showed the best results in this test. This shows that the Catnip and Lemongrass combined will yield better results than the Catnip and Lemon grass alone but the results of this test were unsatisfactory because only half of the mosquitoes tested were repelled effectively. Table 4. 2 Mosquitoes that were effectively killed Experimental| Quantity(number of sticks)| Mosquitoes Repelled| Time Element (minutes)| Catnip| 3| 1 out of 9| 20| Lemon Grass| 3| 1 out of 9| 20|Both Combined| 3| 3 out of 9| 20| The table shows that Catnip and Lemongrass killed only 1 out of 9 mosquitoes but when combined the product repels 3 out of 9 mosquitoes, this proves that the organic incense stick will yield better results if both Catnip and Lemongrass combined, rather than the Catnip and Lemongrass alone because it only kills 1 out of 9 mosquitoes as shown on the table. Table 4. 3 Mosquitoes that are killed by the commercialized product Experimental| Quantity(number of coils)| Mosquitoes Repelled| Time Ele ment (minutes)| Baygon| 1| 9 out of 10| 20|This table shows that the Baygon coil effectively killed 9 out of 10 mosquitoes. This proves that our incense stick with Lemongrass, Catnip or both can’t compete with a better, well known commercialized product like that of the Baygon. Baygon uses stronger chemicals unlike that of our incense stick, which uses organic plants. Chapter 5 Summary, Conclusion, and Recommendations Summary: The researchers made a mosquito coil that is organic and eco-friendly. The researchers also studied between a commercialized mosquito coil with their own mosquito repellent.The researchers also made mosquito traps for trapping mosquitoes for the researchers experiment. Their product is effective and it produced some positive results. The catnip and lemongrass combined shows the best results, based on how much mosquitoes it repelled and killed, throughout the experiment. Conclusions: Throughout the experiment, the researchers found out that the commercia lized mosquito coil is more effective than our organic mosquito repellent. The researchers found out that it is possible to make a mosquito coil using catnip and lemongrass because the two agents are an effective mosquito repellent.Out of the three mosquito coils we had made, the catnip and lemongrass combined showed the best results basing on our experiment. Recommendations: The researchers recommend the people to use natural and safe mosquito coils that can be home made. The researchers also recommend using stronger plants to use in making mosquito coil. The researchers also recommend adding scented aroma to the coils/sticks so it can be a pleasing feeling for the people who will use it. The researchers also recommend using both Catnip and Lemon Grass for making a mosquito coil because it is effective.References: From Internet: Brian, Dan.
