Everybody is supposed to do all sorts of test to identify the bacteria. The first thing I did was smear my bacteria on a liquid medium. I then proceeded to incubate the medium for 24-48 hours. 1. GRAM STAIN The next step I took in finding my unknown bacteria was to gram stain it.This is used to differentiate the bacteria. The different staining reagents are: crystal violet, grams iodine, acetone-alcohol, and grams safranin. Under the microscope it was a pink color, which means Gram Negative. Also, the shape was a rod. 2. KLIGER’S IRON AGAR (KIA) The next step I did was the KIA slant. This is for the Negative bacteria to see if they are in the Enteriobacteriaceae group.

Political ideologies in Brazil Essay Example | Topics and Well Written Essays - 500 words

Political ideologies in Brazil - Essay Example Brazil has become an important country not only in the Latin America but also in the world. In the Latin America, Brazil’s economy is the largest, and it is placed eighth worldwide by the nominal GDP. Additionally, it is currently positioned seventh in the world as per purchasing power parity. As of 2012, the country’s economy growth rate was 5%, and it surpassed United Kingdom’s though there has been a deceleration since (Kiernan, p.5). In light of these, the country’s politics tend to focus mainly on the management and improvement of the economy. To do so, two factions hold different views on the precise methods to improve the country’s economy. While one political group argues that only internationalism would remedy the country’s economic crisis, another vehemently opposes the notion. A statist nationalist is a political group whose ideology is that the government ought to control some areas that crucial to the economy (Almond, p. 45). Using the term, ‘interventionism’, and this political ideology holds the view that only an inward-oriented economy would improve the country’s economic and overall state. Some of the steps proposed by the group is that foreign policies ought to focus what will benefit the country first. The importance of interventionism, it is argued, is that the state corrects market failures while promoting general welfare.

Belkiz Feedaway - Essay Example Assuming that I sell the portable feeding chair at the price of US$150 each, the company will have a demand of as much as 500 pieces of portable feeding chair per month. In case I decided to sell the portable feeding chair at the price of US$350 per chair, the company will be able to sell only 200 pieces of its portable feeding chair per month. (See Graph I – Investment on Price Elastic Product (Portable Feeding Chair) below) A portable feeding chair made out of strong recyclable cardboard is considered as a homogenous product. It means that the product itself can be easily copied by other cardboard manufacturers. For this reason, it is not advisable on the part of Belkiz Feedaway to sell its product as inelastic product. By maintaining the price elasticity of demand, the company will be able to continuously sell the product all year round. To determine the best pricing strategy for Belkiz Feedaway’s portable feeding chair, there is a strong need for the marketing manager to conduct a market analysis which includes market segmentation, targeting, and positioning of the product in the market. Since a portable feeding chair is designed for toddler’s use, the target markets for this product are couples or single parent with new born child. Based on statistics of newborn children each year, the company could estimate roughly how big its potential market is within the United States. Since this product is relatively new in the market, the company can take advantage of pricing the product not too high and not too low. Since there are no other substitute for this product in the market as of the present time, the company has more bargaining power over its target consumers. With regards to product pricing, it is important to consider the volume of portable feeding chair the company can produce. Even though demand for the product is high, the availability of supply could also affect the pricing of the product until such point that the

Corporate Health and Safety - Essay Example In business 'what gets measured gets managed'. Research carried out by RoSPA suggests that the variability in accident rates across UK organisations as a population is so great that any attempt to analyse accident statistics in studies, which consider less than 1,000 organisations are statistically meaningless. In other words, the variability of accident rates in UK industry is so large that the probability of making an error in the interpretation of the results is nearly 100 per cent. A further criticism that can be levelled is that, most often issues such as work related ill health and unsafe conditions are neglected as compare to other, such as the unacceptable exposures to health hazards. Health damage is generally a bigger issue than accidental injury but these are harder to identify and quantify. HSE estimate that early death from past exposure to hazardous working conditions is at least one (if not perhaps two) orders of magnitude greater than death due to workplace accidents (although much of this occurs after those affected have ceased employment). Some may seek to argue that good health and safety management which produces a low a lost time injury rate is more likely to address health protection as well. But an absence of accidents cannot be taken to imply neither a low rate of work related ill health since neither modelling nor data are available to support this. (Director action on Safety and Health, 2004) Although some employers and so-called workplace violence "experts" promote profiling of perpetrators to predict violence, it is often inaccurate and can lead to mislabeling and possibly discriminating against groups of people and workers. Identifying hazards, collecting information and documenting incidents is a very important part of addressing workplace violence problems. Employers are not required to correct hazards, which they do not know exist. Solutions cannot be found for unreported problems. A hazard assessment is a method of identifying, analyzing and documenting workplace hazards. Assessing workplace violence hazards involves some of the same tools used to document any other workplace safety or health problem. These include checklists and surveys, investigating incidents and reviewing available records. 1. Inspect the Workplace - Appendix A contains a workplace violence inspection checklist that can be used as part of a safety and health inspection or safety audit. While inspecting for work-place violence risk factors, review the physical facility and note the presence or absence of security measures. Local law enforcement officials may also be able to conduct a security audit or provide information about their experiences with crime in the area. 2. Conduct a Survey - The most important source of information on workplace hazards is workers. In fact, workers may be the only source of information on workplace violence hazards since management may not document incidents (or near misses). In addition, conducting regular surveys may also enable the local union to evaluate workplace violence prevention measures. Information can be collected either through a written questionnaire distributed to workers or through one-on-one personal interviews. A written survey may be appropriate if the union wants personal or sensitive information. For example, a worker may be reluctant to voice to a union representative fears about a co-worker, but may be more willing to describe the problem in an anonymous questionnaire.

The reality TV and media in The Hunger Games Essay

The reality TV and media in The Hunger Games - Essay Example easure of the upper echelons of the society, is that representatives from each of the districts will participate in a competition for survival from which only one will emerge alive. On the surface level, the novel is a political criticism as those who rule the country are both the organizers of the game as well as its connoisseurs, who repress and exploit their people. However, a more significant aspect of the novel is Collins’ use of moral and emotional rhetoric to criticize the manner in which media and reality shows, as illustrated through the game, are exploiting the sentiments of an audience that sells themselves to cheap gimmicks. Katha Pollitt, a noted writer, opines that the work of Collins can be interpreted as an â€Å"indictment of reality television, in which a bored and cynical audience amuses itself watching desperate people destroy themselves† (Pollit par.2). In the novel, the people in the Capitol seek gory and gruesome entertainment by pitting the teenagers from the 12 districts to fight against one another in a battle of survival. Collins deftly deploys the strategy of the rhetoric of morality by challenging the propriety of a reality TV show, where the participants as pawns. To achieve this objective, she uses the voice of Peeta, a teenage boy from District 12, when and makes the character say that he wants to show the people in Capitol that they do not own him and that he is â€Å"more than just a piece in their Games† (Collins 142). By illustrating such sentiments of the character, Collins primarily wants to communicate to her audience that the people in governance, through the he lp of media and reality shows are in fact exploiting people. Thus, by using the rhetoric device of moral appropriateness, Collins reveals to her audience that the government in Capitol is exploiting their own people. Secondarily, she makes her character retort that he is not a mere piece in their games. By emphasizing the character’s sense of self-respect, the

Outsourcing Work Overseas Essay Example | Topics and Well Written Essays - 250 words

Outsourcing Work Overseas - Essay Example For instance, if an employee in the current home-based organization is given a salary rate of $10 per hour and outsourcing the job would mean that the same position is given an acceptable salary of only $5 per hour, then, a savings of $5 per person per hour would be generated. Likewise, this option also considers that the skills, competencies and qualifications of the workforce are significantly at par with those employees at home. Concurrently, the home organization acknowledges being more vigilant in terms of addressing security and control issues; which could be compromised or threatened due to outsourcing – given the external environment that puts the risk to the home organization. These issues could be justified by placing stringent control measures as well as regular monitoring and performance evaluation schemes. Finally, in terms of technological applications, as emphasized by Putra (2011), is in terms of risk-sharing, to wit: â€Å"the company could minimize risk while at the same time gain access to latest technologies and best practices in utilizing the new system to meet the business objectives† (par. 16). Sharing of knowledge, expertise and applications in required technological systems and processes are likewise facilitated through outsourcing. Strain, M. (2012).

Project one Essay Example | Topics and Well Written Essays - 1000 words

Project one - Essay Example One of the books I liked reading was bed time stories. There is one story I read about a young boy who came from a poor, that most of the days instead of going to school like the other children of his age, he found himself going to the city to sell water. This is because, his mother, the only parent he had; was sick, but she could not raise enough money for the treatment. Despite all the challenges, the boy still managed to be at the top of his class, this impressed the king. The king therefore, decided not only to pay for all his school fees but also paid for his mother’s hospital bills. However, the manner in which the story ended was what captured my attention the most, it ended when the boy who was now around thirty five years old and he became the king of his country. From this story I learnt that we should not let the challenges we face in life bring us down. However, when I joined High school, some of the experiences I have had as a reader are many. For example, in most of the occasions I could not understand what the writer of the article is passing through the article. Most of the times I felt frustrated, therefore I either looked for another book or I could ask my friend to help me understand the information I was reading. As a reader, one of the things that I can ask authors to consider, when writing is the audience which the book or article is addressed to. If it is the teenagers then, it should be written in such a way that the interest of the teenagers is captured whenever they read. Recent surveys have shown that most teenagers do not like reading, this is because of the various games and electronics that are available in the market. As a result, the reading culture has gone down. Most of the researchers argue that if the trend continues then, in the long ran, the country will have a generation of people who cannot read and writ e (Slaouti
