Regression Analysis - Essay Example Lastly, regression analysis will be performed on statistically significant pairs of variables and regression line equation(s) of best fit will be written. Using Excel’s Data Analysis-Sampling, random number for data for country was generated (Figure 1) and corresponding records were taken from population. Table 1 in appendix shows the sample for correlation and regression analysis. Figure 3 shows the scatterplot of the GNP per head and the number of commercial vehicles. The relationship between the GNP per head and the number of commercial vehicles appears to be moderate (correlation, r = 0.556). Table 2 shows the correlation matrix for variables GNP per head, Cars per head and number of Commercial vehicles. The correlation for ‘the GNP per head and the cars per head’ and ‘the GNP per head and the number of commercial vehicles’ is significant at level of significance, ÃŽ ± = .01. Since, the correlation for GNP per head with the cars per head and the number of commercial vehicles is significant; therefore, there is strong possibility that GNP per head can be used to predict the cars per head and the number of commercial vehicles in any country. Table 3 shows the regression analysis output for the GNP per head and the cars per head using Excel. The higher value of F statistic suggests that regression is significant. GNP per head explains about 80% of variation in the cars per head. GNP per head (US $) significantly predict the cars per head,  ÃŽ ² = 0.00005,  t(28) = 10.54,  p   The slope of the regression equation suggest that each US $ increase in GNP per head adds an average of 0.00005 cars per head. The intercept is not meaningful as zero GNP per head implies negative value for the cars per head that is not possible. The regression equation can be used for predicting the cars per head of any developing

Culture Case Study - Essay Example The criteria surveyed on are: diversity recruiting policies, leadership development initiatives, training programs, opportunity for mentorship and activeness of employee affinity groups. All these points to a successful cross cultural management that we can learn from and worth to case studied into. Touching on race and ethnic diversity in the case study, there also are some theories that focus on positive predictions or possible positive outcomes of racial/ethnic diversity. This comes from a "value in diversity" perspective ([Cox, 1993] and [Cox et al., 1991]) which argues that diversity creates value and benefit for team outcomes. Group performance is thought to be enhanced by having broader resources and multiple perspectives (Hoffman, 1959). Particular to race, some studies (McLeod et al., 1996 P.L. McLeod, S. Lobel and T.H. Cox, Ethnic diversity and creativity in small groups, Small Group Research 27 (1996), pp. 248-264. Full Text via CrossRef[McLeod et al., 1996] and [Watson et al., 1993]) have found that ethnically diverse work teams make better decisions than homogeneous teams. The general assumption that underlies these theories is that an increase in racial or ethnic diversity means that a work group will experience possible positive outcomes such as: increased information, enhanced problem s... oblem solving ability, constructive conflict and debate, increased creativity, higher quality decisions, and increased understanding of different ethnicities/cultures. This is true for our case study as Mark Welch, Director of Global Diversity & Inclusion at Northern Trust says in the article (l.5). Because of the diverse background of each individual and culture, when faced with the same problem in the work group, different solutions emerged from the respective culture. Since each culture is unique and so there will be differences, which results in a bigger pool of ideas generated to achieving a problem. This increases the number of comparisons of ideas between one to another. As a result, combinations and hybrids of solutions will surface giving rise to more information. What will be beneficial is that the ability to solve problems will be enhanced since there is an acquirement of new perspectives to solve the same problem, meaning if certain conditions impedes the implementation o f one solution, another solution acquired to the same problem may be more viable. This syndrome is a proof of increased creativity of the individual or of the group. Being in a diverse group, common sense will tell that being sensitive to another's race or ethnicity or hostility will arise. In view of this, to cater to the care of a co-colleague emotions and perspectives very much individualized in a person, and at the same time to disagree maturely based on facts, the way is to bring across constructively conflicts and debates. To achieve so, one will need to seek out the understanding of another's race and ethnicity if an authentic relationship is to be established in the work place. With the increased solutions, there will come about the choice of the best solutions and the motivation

Leading Causes of Morbidity and Mortality in the US

Leading Causes of Morbidity and Mortality in the US The Leading Causes of Morbidity and Mortality in the United States Crystal Mullen ASSIGNMENT: Research the leading causes of morbidity and mortality in the United States. What are the leading causes? Why is it important to be aware of them? Write a 4-5 page APA formatted paper discussing your findings. You will need to include a minimum of 3 references to support your findings and opinions. Before beginning this assignment I was thought morbidity and mortality referred to things that are scary, gross and filled with gruesome deaths. I thought that morbidity referred to what I saw on Halloween or some horror movie. As it turns out morbidity refers to: â€Å"the incidence or prevalence of a disease or of all diseases in a population (Medical Dictionary, 2014)† Based on this definition I can see that morbidity is data collected regarding the various diseases that can afflict a population (Diffen, 2014). Furthermore, I saw mortality simply as a fancy way of saying that everyone is going to die. Because my view of mortality was overly simplified, I didn’t appreciate the weightiness of this information: â€Å"Death, especially of large numbers; heavy loss of life (The Free Dictionary, 2014).† Based on this definition, mortality is more than just dying, it’s documenting populations that have died. This data can be separated into different categories: perinatal mortality rate, crude death rate, maternal mortality rate, infant mortality rate, child mortality rate, age-specific mortality rate, and standardized mortality rate. Once the data is collected it goes to the National Vital Statistics System so that the information can provide cause of death information based on geography and demographics (Diffen, 2014). Therefore, having an understanding of the difference between morbidity and mortality, I can further research the leading causes of morbidity and mortality in the United States. Based on what I’ve found, the top five causes of death, or mortality, in the United States are heart disease, cancer, chronic lower respiratory diseases, strokes, and accidents. Heart disease is the number one cause of death in the United States. The Centers for Disease Control and Prevention (CDC) has documented that approximately 600,000 individuals will die of heart related illnesses in the United States every year. In fact one of every four individuals will die of heart disease. Furthermore, coronary heart disease, the most common form of heart disease will kill over 385,000 people in the United States this year alone. Finally, though not exhaustively, every year, 715,000 Americans suffer from a heart attack. These are simply the statistics for heart disease (CDC, 2014). There are quite a few risk factors that enable individuals to be susceptible to heart disease. First of all, individuals who smoke, have high blood pressure or high LDL cholesterol. Furthermore, individuals will increase their risk for heart disease if they struggle with a healthy weight, eat unhealthy live a sedentary lifestyle or drink alcohol excessively (CDC, 2014). Sadly because this is the lifestyle of many Americans, they are continuously vulnerable to hearth disease. However, while these risk factors are excessive, there are ways for Americans to reduce their susceptibility to heart disease simply by making healthy food choices that are low in salt and fat and high in fiber and protein. Furthermore, it has been proven that limiting alcohol intake and daily aerobic exercise will lower a person’s blood pressure and LDL cholesterol. These changes will lower a person’s vulnerability to hearth disease (CDC, 2014). The second leading cause of death, mortality, in the United States is cancer. The ten most prevalent in the United States include cancers of the prostate, breast, lung and bronchial, colon and rectum, corpus and uterus, urinary bladder, skin, non-Hodgkin lymphoma, kidney and renal pelvis, and cancer of the thyroid (CDC, 2014). At this time there are no explanations why one person will develop cancer while another person won’t. However, there is research that links certain risk factors to a person’s susceptibility to suffer from cancer. Certain risk factors, such as growing older, family history, sunlight, and even certain hormones and radiation may be beyond an individual’s ability to control. However other risk factors, such as excessive alcohol consumption, poor diet, a sedentary lifestyle, or obesity are risk factors every individual can avoid. Furthermore, annual check-ups with a healthcare clinician can also warn an individual of additional risk factors to avoid (National Cancer Institute, 2014). Chronic lower respiratory disease is the third leading cause of mortality in the US. Chronic lower respiratory disease refers to persistent, continuing diseases of the lower respiratory tract. Examples of Chronic lower respiratory disease includes COPD, Emphysema, Chronic bronchitis, and Cystic fibrosis. The symptoms of this disease include are shortness of breath, coughing up blood, chest pain, wheezing, loss of appetite, loss of weight, and bluish discoloration of fingers and lips (Right Diagnosis, 2014). There are quite a few risk factors that increase a person’s chances of chronic lower respiratory disease. Certain risk factors, such as chemical fumes, air pollution, and long term to exposure second hand smoke is beyond a person’s control to prevent. However, risk factors such as smoking can be eliminated so minimize a person’s vulnerability to chronic lower respiratory disease. Strokes are the fourth leading cause of death, mortality, in the United States. Strokes are the equivalent to a heart attack in the brain. This is because the blood vessels in the brain rupture when the blood supply to the brain is blocked. When this happens, brain tissues die and generates a weakness or numbness on half of the body. A stroke is a medical emergency, but with quick treatment to the stroke victim, it is possible for the victim to avoid physical disability and death (CDC, 2014). As with the other causes of morbidity, there are quite a few risk factors of having a stroke that are both within, and beyond an individual’s control. For example, risk factors like family history are beyond an individual’s control. However, behavioral choices such as poor eating habits, sedentary lifestyle, obesity, smoking and excessive alcohol consumption are risk factors that can be avoided to reduce a person’s chance for suffering a stroke (CDC, 2014). I believe that because there so many ways to prevent a stroke, this must be the reason why it is the fourth and not the first leading cause of morbidity. Finally, the fifth leading cause of death, mortality in the United States is accidents. There are many forms of fatal accidents including (but not limited to) death by motor vehicle, vehicles, poison, slip-and-fall, choking and even fire. Motor vehicle accidents happen all too quickly and far too easily simply when the drivers get distracted. Car (vehicle) accidents often happen when the driver is doing everything else while driving such as texting, talking on the phone, applying makeup, or even shaving. Poisoning occurs either with tainted food or water, as well as ingesting legal and illegal drugs as well as various pesticides. The most common forms of poison are hydrocodone, heroin, cocaine and even alcohol. Although people do die from falls, this isn’t usually a problem for individuals under 65 years old. Death by fire occur either from carelessness such as a paper close to a fire or perhaps falling asleep while smoking. Finally, just as senior citizens are at the highest risk for falling, toddlers are at the highest risk of choking. So it’s a good idea to remove food or small toys out of a child’s unguarded reach so that they won’t suffer from choking (Listosaur.com, 2011). Based on what I’ve read, all accidents are preventable yet all accidents can be deadly. Conclusion Based on what I’ve read, and based on my own lifestyle, it is very important not only to be aware of risk factors of diseases because I am then armed to prevent them in my life. First of all, if I know risk factors for heart disease include poor eating habits, then I can create a meal plan that is low in salt and fat and high and fiber and protein. Furthermore, if I know that one way to avoid lung cancer is to avoid situations where I’m ingesting second hand smoke, then I know to avoid areas of work where people are taking their smoke break. Finally, though not exhaustively, if I know that a risk factor for a child to choke are innocuous food like grapes, stew meat, or nuts, then I know I need to cut up my little one’s food into tiny bite sizes so that he or she can enjoy the food without obstructing his or her windpipe. Therefore, if I take care of my health, I have a greater chance of living a long and healthy life. References CDC. (2014). Cancer Prevention and Control.

Diction And Imagery In The Poe :: essays research papers

The Challangers Quest   Ã‚  Ã‚  Ã‚  Ã‚  The world today can be a dangerous place, causing people to be precautions. To be a risk taker in today’s society involves courage and a willingness to be vulnerable. In the poem“Swimming alone,'; author Patricia Keeney uses diction and imagery to convey that venturing into risky situations requires one to be brave and yet desperate.   Ã‚  Ã‚  Ã‚  Ã‚  The swim is presented to the reader as an enormous challenge that only the brave and desperate would face, such as a player in a challenging computer game. Diction such as ‘dangerous’ and ‘trouble’ used throughout the swim maintains the risk the swimmer must face. The line“whirled pearl smoke,'; signifies confusion which heightens the unsureness of the situation. Vulnerability becomes evident as the swimmer suffers “cunning furtive spasms.'; The challenge heightens and the swimmer is represented as an “angry isolate.'; Like a computer game special affects are added in to increase the danger such as the lightning and the darkness.   Ã‚  Ã‚  Ã‚  Ã‚  Imagery such as “Deliberately fracturing glass moving down through pools'; conveys the mental picture of the water being glass shattered with every stroke. Shattering glass suggesting danger and fear. “Barely missing the moon’s pale hiss,'; portrays the image of a deadly snake, heightening the risk of the challenge. The depiction of “white nudes between each sizzling shaft,'; brings to the reader the vulnerability the swimmer feels running from one danger to another. Also, the affect of a challenging computer game is again played. The swimmer is like a loosing player challenging each feat and then faced with yet another.   Ã‚  Ã‚  Ã‚  Ã‚  Some goodness comes out of taking the risk of swimming alone. Ones“prohibition and expectations are ignored.'; The challenger of this feat has let go of all egoism as a result of the vulnerability faced.

Barangay Information System Essay

Significance of the Study -This study was made to find out that the use of residence information system will lessen the time for the transaction of encoding. Also in using this system it can recognize the person involve in this study. To the Barangay – It will help for them to lessen the time for the transaction of encoding. The system will be the census like having a system of the barangay for all of its constituents and new people who will live in the place. The system will be effective in maintaining, searching and storing of records of all resident in the barangay. To the Residence – For they will be accommodated easily for they will have an identification that can be used to access their accounts if there are some changes to be done in their part. It will also be easy for them in requesting some information and services because the barangay had already have it. This will also assure the residents that their information is properly secured and maintain through the manipulation of the proposed system. To the Secretary of the Barangay – It will help to organize the record and monitor the information of the residence. Foreign For further understanding of the study, the researchers made use of different reading materials related to the information system. These materials such as books, magazines, newspapers, thesis and other web articles are essential in broadening the knowledge of the researchers. These will also guide the researchers to achieve their target objectives by getting ideas on other related studies and make improvements as possible.   According to Jennifer Rowley (2005), information system are a tool to support information management. Information systems are increasingly being used in organizations with the object of providing competitive advantage. The information systems used by organizations can be grouped into different types such as transaction processing system, executive information system,  expert systems and office information systems. Information Technology has heralded the advent of the information society. The University of Minnesota Research and Training Center has released its annual Residential Information Systems Project report. The report provides state-by-state statistics with long-term trends on residential services, settings, populations and expenditures for people with developmental disabilities in state, nonstate, and Medicaid-funded residential programs. Characteristics of residents, movement and staffing patterns in large state residential facilities are included. The report uses 2012 data to examine trends in residential supports for people with developmental disabilities. The report found that the majority of people with IDD that do not live with a family member live in a setting with three or fewer people with IDD, with more than three-fourths sharing a home with six of fewer people. The report notes that there are significant differences in the data between states for many topic areas, including setting size, waiting lists, and average expenditures for HCBS. O’Brien, (2011) defines information system as the organized combination of people, hardware,software, communication networks and data resources, that control, transform and disseminateinformation in an organization. In partial fulfilment for the requirements in Software Project presented to the faculty of IT Department Ebora, Vanessa Grace I. Casas, Lori Anne S. Rapisora, Sheryl L.

Five Forces Analysis-US Express Mail Industry Essay

Question 1 asked to complete a five forces analysis of the US Express Mail Industry. A five forces analysis is done to rate the attractiveness of an industry. Threat of new entry is low because the barriers to entry are high. Newcomers to the industry would require an enormous amount of up front capital to set up the distribution networks and infrastructure, such as establishing hubs, and acquiring aircraft and a large amount of ground transportation vehicles (vans, trucks, ect). Economies of scale are significant and would deter new firms from entering because initial sales volumes would be low do to the fact that existing brands already have strong brand identification, and there are no cost advantages to entering, like government subsidiaries or favorable locations. There would also be aggressive reaction from the three main players (FedEx, UPS, Airborne) since the level of rivalry is already so high. Buyer power (customers consisting of businesses and the general public) is high mainly because the large volume of customers have no brand loyalty in the express mail industry. Customers base their selection of a carrier on reliability, price, and convenience and there is not much product differentiation in any of those areas between carriers so customers can bounce around between carriers, essentially playing the competitors against each other, forcing prices down and demanding higher quality and services. Supplier power is high overall. The main inputs, or supplies, for the express mail industry are fuel, airports, aircraft, ground transportation, and the employees. The employees are unionized and have the power to demand higher wages and benefits, they may not always get that, but then there is the potential for strikes, like with UPS, which costs UPS $700 million in revenues and hurt their reputation. Fuel is another supplier power that is high. Fuel is a key component and there is limited bargaining when it comes to negotiating fuel prices. Another key product is the airports, there are only a few in each major city, and the carriers have to go where they have to go, hitting those hubs in major cities, thus causing there to be little bargaining power with airports. The airports and the aircraft suppliers aren’t only relying on the express mail industry, so that also gives those suppliers more power to charge what they want (landing fees, cost of planes). Ground transportation vehicles is the only input that would allow for more bargaining power since there are numerous alternatives available, there is more room for the  industry players to negotiate price. The availability of substitutes is medium mainly because there aren’t a large number of substitutes out there for express mail outside of the industry. Most next day deliveries are business documents, parcels, letters, ect, not typically cargo. So substitutes could include email and faxes, both are faster and cheaper than express mailing. Depending on the nature of the business, video conferencing or the old fashion telephone could be used. If the parcel is going somewhere local maybe could use bike messengers, or just hand deliver. There are also the second tier players, like RPS, DHL and TNT, while they are still in the delivery industry; they tend to specialize in areas other than express mail. With RPS, it is second day service at 40-50% less, and a business that does a large amount of overseas or international express shipments may want to substitute with DHL or TNT, who specialize and differentiate themselves in the international market. The Intensity of rivalry is high. The domestic express mail industry only consists of three major firms, UPS, FedEx, and Airborne, and six second tier firms, such as DHL, RPS, and the U.S. Postal Service so there isn’t a high level of concentration. The big three make up 85% of the U.S. express mail market. There is intense competition, when one company lowers prices, so does another, leading to price wars. When one company improves it technology or offers more service, so do the others, leading to difficulty in differentiating products. Fixed costs are high (planes, hubs, transportation) and when fixed costs are high it causes companies to want to reduce prices in order to sell more and generate more revenue, but the revenues have not kept up with falling prices and has caused the industry growth to be slow so the companies are all fighting for market share. The exit barriers are also high, financially and non-financially. Financially because of the enormous amount of capital that has been invested (fleets of planes and/or trucks, set up of the distribution networks and infrastructures), and non-financially, mainly due to social costs. People conduct business everyday and rely on urgent delivery of time sensitive information (documents, contracts, and perishables like medical samples) and not having the services of the express mail industry to deliver those time sensitive parcels could cripple the economy, for example when UPS when on strike for 16 days, there was a â€Å"noticeable disruption† to the economy as a whole. So in conclusion, based upon this analysis, the US Express Mail Industry in terms of profitability is very unattractive and would be considered unattractive by any firms considering entering as well.
