The Pregnancy Of A Bacteria Called Group Beta...
Modern day science has allowed us to make pregnancy and childbirth safer and more predictable than ever. However, we are not invincible to the many organisms that share our world and they can pose some serious risks for both the mother and the infant during this critical period in life. One such risk that many mothers donââ¬â¢t think about is the potential colonization of a bacteria called Group Beta Streptococcus (GBS) in their body during pregnancy, specifically around the time of birth. Lab testing and antibiotic prophylaxis can be thought of as risk-management and has proven to be effective at reducing GBS infection rates in infants born through the vaginal canal of mothers who are GBS carriers. Group Beta Streptococcus (GBS) is a bacteria that is found in the vagina and rectum of 10-30% of all women. This bacteria comes and goes as it is normal flora for women, similar to yeast. Although most are asymptomatic, some may experience urinary tract infections while the bacteria is present in their body. Although GBS does not present much of a problem to the carrier, this specific bacteria can cause much harm to a newborn who passes through the vaginal canal during birth (ACOG, 2011). Pregnant women can take advantage of modern day screening procedures that look for the presence of GBS in late pregnancy to determine if antibiotic prophylaxis is warranted. It is approximated that 50% of all newborns will colonize GBS on their skin during a vaginal birth. However, colonization

Impact Of Terrorism On African Progress - 2058 Words
Introduction: Africa faces many problems which boycott its transition from predominantly the frontier market to the emerging market sector. This essay will discuss the impact that terrorism and militancy have had on African progress, and, outline the successes and failures of the approaches that have been taken to combat this. Terrorism is still without a concrete definition however the UN Security Council uses ââ¬Å"Criminal acts intended or calculated to provoke a state of terror in the general publicâ⬠(United Nations, 2015) as way to condemn terrorist acts. For the purpose of this essay we will use regional examples from Nigeria and Somalia to show a variety of situations rather than consider African terrorism as a whole. Additionally weâ⬠¦show more contentâ⬠¦This Act prohibits the financing of terrorism and the act itself along with placing obligation on financial institutions to report suspicious spending. Since then the countryââ¬â¢s criminal justice systems have been stren gthened along with numerous arrests having been made (Onuoha etal, 2011). Nigeriaââ¬â¢s cooperation in Global affairs has also increased including collaborating with the U.S. in anti-terrorism exercises (U.S Department of State, 2013). The country has also made significant progress in regulating the financing of terrorism. A significant mile stone was crossed when Nigeria was taken off of the FATFââ¬â¢s list of countries subject to monitoring for money laundering and terrorist financing (U.S Department of State, 2013). These advances have had a positive effect on the stability of the country however there are many inadequacies that led some to refer to the act as a ââ¬Å"Toothless Bulldogâ⬠(Toyin, 2012). Major criticisms include the Act does not issue the protection of fundamental human rights to the terrorists in question (Onuoha etal, 2011). This is regressive at best in terms of human progress. As told by Dakas, C. 2012. p.1 ââ¬Å"The temptation for governments and parliaments in countries suffering from terrorist action is to fight fire with fireâ⬠. He then continues ââ¬Å"For a State to react in such a way would be to fall into the trap set by

Data Analysis And Modeling Report Case Study Of Employed People
Question: Discuss about the Data Analysis And Modeling Report Case Study Of Employed People. Answer: Introduction The study adopted a descriptive cross-sectional survey research design. The data was collected from sample of employed neighbors and friends. The survey was conducted with aim of utilizing data for practical purpose in data analysis and modeling. The method of data collection was questionnaires administered to them to fill some questions. I used simple random sampling to selects a sample of thirty respondents who had each chance of being selected in sample. The data was then entered and cleaned using Excel version 2007 software. The data has seven variables, age of respondent in years, gender of respondent where 1 represent male and 2 female, the number of degrees one have as measure of education level, hours the respondent used in work in a year, salary one get per year, number of kinds the respondent have and marital status( 1 represent married and 0 unmarried). The sample represents a population of employed persons in the area. Who have formal education and are below 35 years. Age of respondent, number of degrees, wages and hours of working hours are numerical data while gender of respondent is categorical data. Data analysis methodology Descriptive and inferential data analysis was used to analyze the data on Excel 2007 software. The descriptive statistics include mean, standard deviation, histograms. While Chi-square tests association is used to test significance. Chi-square provides a method for testing the association between the row and column in two way table. Chi-square statistics= Where the chi-square statistics have chi-square distribution with (r-1)(c-1) degrees of freedom. Where r represents number of rows and c represent numbers of columns in the table. Scatter diagram were used to check linear relations of various variables. The report will cover the following histogram of number of hours worked and wages to check their distribution. Scatter plot of working hours and gender to check any association or causal between the two variables. The relationship between wages and working hours is tested using regression analysis. Linear regression model where y is wages earned and x is number of working hours per year. Correlation Coefficient is given by (r) = {n x y ?x y [nx2 ? (x)^2 ][ny2 ? (y)^2] } Analysis and Report The average age of respondents is 28.66667 years with standard deviation of 1.24106, the mean wage of the respondents per year is 51200.87 with mean working hours per year of 2996.1, average number of degrees one have is 2 and on average each respondent has one kid. This are measures of central location of the data distributions. The data is skewed to the right with majority of respondents working below 5000 hours per year. The distribution is not normal and has one outlier working above 20000 hours per year. This affect mean as measure of location and give a false picture of the data. Majority of workers follow on wage bracket below 100000 dollars per year regardless of working hours and the level of education one, has few of employees earn above 100000 dollars which are extreme values of data. There is no relationship between genders and working hours, gender do not affect number of hours one work to earn wages. The two variables are independent of each other. The correction between gender and working hours is zero. This means when one decrease or increase the other is not affected by changes occurring to the other variables. Chi-square tests of association between gender and marital status Chi-square provides a method for testing the association between the row and column in two way table. It is measure of association between two categorical data such gender and marital status in the study. Chi-square statistics= Where the chi-square statistics have chi-square distribution with (r-1)(c-1) degrees of freedom. Where r represents number of rows and c represent numbers of columns in the table. The null hypothesis is there is no association between gender and marital status. Against alternative there exist association between gender and marital status. The level of significance is 5% for the test statistics. Gender/ Marital status Married (observed) Expected Not married(observed) expected Total Male 11 12 9 8 20 Female 7 6 3 4 10 Total 18 12 30 Chi square test 0.429195 with 2 degrees of freedom, p (0.429195) = 0.806866 which is greater than level of significance 0.05 this means we fail to reject null hypothesis and conclude that there is no association between gender and marital status. Gender or being male or female does not affect the marital status of the respondent. Marital status is independent of gender. The result are insignificance, the difference between the expected and observed values under null hypothesis is negligible. Thus chi-square test fails to associate gender and marital status. It implies that the choice of getting married or not is being influenced by other factors not gender. Analysis of one relationship between gender and working hours Bar graph of working hours means of males and females. Majority of female employees works 2000 hours and below per year while men work for more than 4000 hours per year. The data portrays large significance differences between mean working hours of female and male. On average male spend more hours working per year as compared to females. The average male working hours is 3485.9 while female is 2016.5 with mean differences of over 1000 working hours. Working hours is associated with gender with female working fewer hours compared to males this may be affected by marital privilege or other commitments. The mean working hours is higher in females as compared to males, thus gender affect working hours. Relationship between wages and number of working hours The first step in studying the relationship between two continuous variables is to draw a scatter plot of the variables to check for linearity. We plot scatter plot with x axis being working hours and dependent variable wages. Majority of employees work between 2000 hours and 3000 hours earning below $100000 and few work above 6000 hours though the wages is not increasing above $100000. There is no linear relationship between number one spend working per year and the amount of wages one earn. Some works less than 2000 hours in year and they earn more than 100000 dollars, while others work more than 6000 hours per year and earn less than 100000 dollars a year. Increase in working hours does no increase wage one earns and decrease in working hours does not result to a decrease in wage one earns. The two variables are not correlated with each other. The data is highly skewed to the right hand side with many extreme values. These outliers affect the average giving false picture of data. They also affect the correlation and should be check if they are real data or errors. The Pearson moment product correlation coefficient measures the strength of association between independent and dependent variable. The Pearson moment product correlation coefficient is 0.299 which measure strength of linear association between wage earned and number of working hours in a year. The correlation coefficient is close to zero. It indicates weak linear association between working hours and wages. Regression analysisis a statistical process for estimating the relationships among variables. It includes many techniques for modeling and analyzing several variables, when the focus is on the relationship between adependent variableand one or moreindependent variables. Regression analysis helps to exclude those values that do no have significance importance in the predicting dependent variable. Running a linear regression model Where y is wages earned and x is number of working hours per year. SUMMARY OUTPUT Regression Statistics Multiple R 0.093646 R Square 0.00877 Adjusted R Square -0.02794 Standard Error 34028.03 Observations 29 ANOVA Df SS MS F Significance F Regression 1 2.77E+08 2.77E+08 0.238872 0.628968 Residual 27 3.13E+10 1.16E+09 Total 28 3.15E+10 Coefficients Standard Error t Stat P-value Lower 95% Upper 95% Lower 95.0% Upper 95.0% Intercept 42710.94 12411.24 3.441311 0.001899 17245.18 68176.71 17245.18 68176.71 7780 1.844106 3.77314 0.488746 0.628968 -5.89774 9.585949 -5.89774 9.585949 R Squared is 0.093 which means working hours only explain 9% change of respondent wages and the model is not a good fit. R Squared is 0.093 means that when predicting a persons total income, we will make 9% fewer errors by basing the predictions on the persons hours of work and predicting from the regression line, as opposed to ignoring this variable and predicting the mean of income for every case. Hours of work(X) explain 9% of the variation in income(Y) among city employees. A slope of 1.844106 means that 1-hour increase in an employees amount of working hours result to an average increase in annual income of $ 1.844106. A y-intercept of 42710.94 suggests that the expected income for a person with 0 hours of work should be $ 42710.94. Moreover, from the data t= 0.488746 and p-value= 0.628968, we can conclude that the slope for hours of work is not significantly different from zero at p is greater than 0.05. Conclusions Descriptive and inferential data analysis was used to analyze the data on Excel 2007 software, the following were obtained. The average age of respondents is 28.66667 years with standard deviation of 1.24106, the mean wage of the respondents per year is 51200.87 with mean working hours per year of 2996.1, average number of degrees one have is 2 and on average each respondent has one kid. Gender or being male or female does not affect the marital status of the respondent. Marital status is independent of gender. There is no association between number one spend working per year and the amount of wages one earn. Increase in working hours does no increase wage one earns and decrease in working hours does not result to a decrease in wage one earns. The Pearson moment product correlation coefficient is 0.299 which measure strength of linear association between wage earned and number of working hours in a year. The correlation coefficient is close to zero. It indicates weak linear associati on between working hours and wages. The chi-square of association between gender and marital status produced results as follow. That gender or being male or female does not affect the marital status of the respondent. Marital status is independent of gender. The result are insignificance, the difference between the expected and observed values under null hypothesis is negligible.

Medical Biochemistry for Embryo and Starchy - MyAssignmenthelp.com
Question: Discuss about theMedical Biochemistry for Embryo and Starchy. Answer: Introduction A wheat kernel has three main sections- embryo, starchy endosperm and protective layer. For a plant to carry out germination, many cells and cellular materials reproduce from the original embryo. Acid phosphate is a major enzyme produced for the initial stage of germination. This enzyme is responsible for breaking down phosphate esters and releasing the phosphate for necessary metabolic activities. In this experiment acid phosphate is to be extracted from wheat germ and its enzymatic activity is to be determined. The results would be then compared with the standard graphs produced in experiment 3A and the amount of acid phosphate would be determined.

Introduction It is crucial to determine the molecular and physical properties of a protein in biochemistry for understanding the unique characteristics and all possible downstream application. Electrophoresis is a commonly used method in biochemistry for separating protein and nucleic acid. One significant method for purifying proteins is using polyacrylamide gel electrophoresis (PAGE). The widely used method, called protein denaturation, applies sodium dodecyl sulphate for stripping down the protein into linear amino acid sequence for producing better migration pattern in the gel. This is termed as SDS-PAGE process. From previous In this experiment the proteins within the extract would be separated through SDS-PAGE method for determining the different forms of protein present within the wheat germ extract.

New Trends In High-Tech Recruiting Essays - Employment,
New Trends In High-Tech Recruiting There is a new trend developing in the recruiting of high-tech employees. Due to the competitive nature of the business, companies are looking for new ways to recruit individuals that not only have the business and technical knowledge required to perform a specific job, but they are also looking for candidates that fit well into the corporate culture of the organization. Tech Planet is one such high-tech firm that is using this new approach to recruiting. Instead of the normal first round job interview, applicants at Tech Planet sit down to an informal meal with employees. The goal is to socialize with the employees to determine whether the applicants belong in the organization. After the initial meal, employees vote on which candidates will be invited back for the next round. During the second phase, job applicants are asked to?bring an essay explaining how they feel about working with small businesses and how they envision their next job - plus an inanimate object that best describes them. Objects brought by potential candidates in the past have included Silly Putty, soccer balls, hair gel, and pictures of family pets. Several other companies, including executive recruiters, are transitioning from a traditional approach to this new unorthodox method of screening applicants. At some firms, candidates are asked to play touch football or Yahtzee with other employees. The belief is that these activities can demonstrate an individual's ability to work in a team setting and how they will get along with colleagues. Though this appears to be a new trend in the world of recruiting, some employment experts question the value of this new approach. They feel that companies may overlook the most highly skilled applicants in search of people who are just fun. Another trend in the high-tech business world is the scarcity of information technology employees. Recruiters are facing new challenges in filling open positions within both technology and non-technology firms alike. Typically, the high-tech firms, new start-ups with hopes of going public, are having an easier time filling their IT positions as they focus on higher wages, bonus compensation, and stock options. Conversely, non-technology companies with IT needs are finding it difficult to entice qualified candidates to fill their openings. They just can't offer the perks that other technology companies are offering and are losing potential candidates as a result. Today's generation is motivated more by instant gratification and high incomes than benefits packages including medical and dental insurance. In my experience as a manager, I have found it difficult at times to find the best candidates for positions for which I'm recruiting. Though there may be several applicants who possess the necessary technical and business knowledge to perform the tasks, there is a level of uncertainty regarding their ability to work within the culture of the organization. Formal interviews are beneficial in determining some behavioral tendencies, but it is still difficult to determine how individuals will work with others in the organization if hired. If we were to implement a new approach similar to the one depicted in the article, we might be better able to foresee how the candidates will work within their teams, with their co-workers, and with their managers. The interaction could also help uncover any negative tendencies that may be present that might not normally surface until the candidate has been hired into the organization. I agree with the employment experts that organizations may wind up hiring people who are just fun, but that's a risk that may be worth taking. Business and technical knowledge can be learned by most individuals that have a minimum set of skills, but personality and behavioral skills are much more difficult to alter. Personal skills are not typically learned through any coursework or training that individuals may attend but through life experiences, though these may include training of some kind. I would prefer hiring candidates who I felt reasonably confident would fit into the organization and could learn the required business and technical skills rather than hiring individuals who already had the business and technical knowledge but would not have the ability to fit in the organization. In addition, I feel that companies should do more market research to determine what types of

Guncontrol essays
Guncontrol essays In general, guns have been a major problem for years upon years. The threat of guns in cities and towns is astonishing. Many people in the United States are fighting to ban guns everywhere, others think they should have the right to own a gun with no questions asked. Considering the amount of handgun deaths, many people ask the question Are guns killing people or are people killing people? Many people are in the fight to gain stricter laws on guns, Yet just as many are opposed to the idea of stricter laws. Guns started to become an issue in the late 1970s and early 1980s. In 1977 guns were the weapons used in approximately 70% of the murders in the United States.(Encarta Online) 60% of all murder victims in the United States (about 12,000) were killed by firearms, and 70,000 were injured. During the early 1980s Hip Hop and Rap became popular. This increased the number of gun conflicts greatly because of the image of a rapper.(Dennis, Debate) Heavily populated cities had an increasing amount of gangs during this time.(Dennis, Debate) The gangs would sell drugs and use guns to back them up if a deal went bad.(Dennis, Debate) Guns were easily accessed due to the heavy gang activity.(Dennis, Debate) People were being shot everyday as a result in these gangs. Many people were trying to fight the spread of guns and get a stricter law on accessibility to guns. People who want gun control have a very hard time convincing government officials to do something about it. The Republican controlled Congress has doubts because of what the Second Amendment said about guns. Handgun Control Inc. (HCI) said, The Second Amendment poses no threat to the laws affecting the private possession of firearms, and this may well be the most settled proposition in constitutional law.(Dennis, Debate) HCI also wrote a letter...

How Does Communication Differ in Helping Relationships Essay
How Does Communication Differ in Helping Relationships - Essay Example This research will begin with the statement that man is a social animal. With time, the definition of social life has changed to the extent that technology has taken over the minds and thinking of men and women whom we see around us. Every person in the urban society is addicted to web-based social networking sites like Facebook and Twitter, through which he can easily find new friends and social contacts who share common interests. Counseling is a society friendly word that is being used extensively these days. However, with different counseling and communication methodologies around, it can be tough to define their best applications. In fact, there are suitable methodologies which refute the traditional or conventional approach to setting things straight within the human mind. Trying new approaches will only help prune up the existing methodologies. Treating an alcoholic or a drug addict is strikingly different from psychological treatment meted out to suppressed teenagers with boy friend or family issues. If knowledge has to form the basis of all the counseling methodologies developed till now, then with our study of specific cases of depression and underperformance, we try to develop a new set of easy methodologies that can be applied to all cases of depression and counseling. It does not take much effort to make a man or woman smile, take control of the problems he or she is facing and install the conviction that the outcome is going to be all positive. This is precisely what psychological counselors need to do on a daily basis.
