Essays on Population

Many individuals from these three group ages participate in lifelong learning outside the traditional university or college setting, training programs and advancement in career. In the US, 53 percent of younger adults and 38 percent of the older adults took part in some form of lifelong learning. This shows that lifetime learning is common. The surprising fact is that still very little is known about making learning better in populations other than the ones used in traditional college and university settings because of convenience with which university students can be examined. This leaves many issues unclear ...

Introduction

Causes of food shortage There are three factors that lead to food shortage; they include environmental, economic and social factors. Other factors causing food shortage are overpopulation and poor government policies that lead many countries in scarcity of food. Food distribution to the masses is determined by the socio-political factors. The production and growth of crops in a given area is determined by the environmental factors. While on the other hand, economic factor affects the buying and production capacity.

Social factors causing food shortage include increase rate of the population which is higher than food production. High rate ...

Condition such as a disease, before and after a diagnostic test, respectively. The result of the diagnostic test could be either positive or negative. In reality, the subjectivity of the probabilities is merely based on a piece of information, whether an individual has a condition or not. The condition is regarded as a psychological phenomenon to those who go through a certain diagnostic test. In addition, the probability is always a 0 per cent or a 100 per cent result. The difference between the pretest and posttest probabilities on a certain condition is a major ...

1. A t-test would be of help in comparing the two different groups' blood pressure average before and after being subjected to the drug. The difference will be meaningful and real if:

The responses are constantly close enough to the average value with a low standard deviation from the mean value. The differences between the averages are large.

The t test effect size and the t test statistical significance are the two primary outputs of the t test. Statistical significance helps indicate whether the difference existing between sample averages represents actual differences between my populations (my two group ...

Question#1

The null hypothesis is a hypothesis, which is checked for consistency with the existing sampling (empirical) data. Often used as a null hypothesis act hypothesis of no relationship or correlation between the studied variables, no differences (homogeneity) of the distributions (or parameters of distributions) of two and / or more samples. The standard scientific approach for testing hypotheses the researcher attempts to show the failure of the null hypothesis of its inconsistency with the available experimental data, that is, to reject the hypothesis. This implies that there must be adopted another, alternative (competing), excluding the zero hypothesis. Used in the statistical ...

Religion is regarded as one of the most important and impulsive identifiers of a culture as it consists of moral values and principles that have a strong foothold in the conventional cultural model. For the same reason, when one’s religion is threatened, it puts everything at risk; past, present and future (Simonsen & Spindlove 17). The same has happened in China where the Muslim Uighur from Xinjiang have formed activist groups in order to protect their religious standing and have an independent Islamic state of their own. The history of Uighurs’ independence dates back to A.D. 744. ...

In a modern world people are drowning in the large volumes of data. Thousands of papers and researches are being published every day to support or refute some kind of statement. Is smoking associated with lung cancer? Did educational reform increase the efficiency of education system? Is the new medicine a better way of illness treatment? All these kinds of questions are trying to be answered by statistical analysis which often includes flaws and fallacies. Some institutions manipulate the statistics intentionally, while others fail to provide society with a reliable result because of a poor knowledge of statistical techniques.

The vaccine helps prevent the contraction of the disease and it is important for people to take it. HPV is not a common virus, and those infected may not even know that they have been infected with the virus. In most cases it does go away on its own, but when it does not it causes cancer and genital warts. The real problem is that even with the vaccine present, there seems to be a prevalence of the virus. HPV can cause cervical cancer and it is important that parents embrace the change about the vaccine.

Genetically Modified Organisms have perhaps been one of the most controversial and debatable topics lately. There has been a huge debate about the safety of their consumption and various associated implications. There are two different and opposite lobbies and while one supports Genetically modified organism, the other detracts and criticizes them. There have been many studies and researches on the safety and efficiencies of GMOs and the results have been mixed and confusing.

The article ‘Altered Food, GMOs, Genetically Modified Food’ by Jennifer Ackerman does a commendable job at explaining everything about the genetically modified organisms. The article published in ...

As articulated by Bittman (2008), in the article “ Why worry about food and water?,” which featured in the New York Times, Sunday Magazine's series, the correlations between American households with food are significantly dynamic as evidenced by rapid changes aligned with food preference, preparation, and consumption. As such, the notions contained in the article primarily target American households, which have since time immemorial been faced with various disparities with regard to food preparation and consumption. Worth noting is the fact that the beginning of the 20th century has been clouded by issues of food safety whereby low quality foods ...

DISCUSSION

Antidepressant and anxiolytic effects of smoking are known to the smoking population, despite the popular belief that smoking has a positive mood affects. The evidence established in Boden, Fergusson, & Horwood (2010) and other literature that have linked smoking to depression assert that the smoking population may actually be vindicated. Regardless of the direction of the causal relationship; it is still a statistically significant relationship with important practical implications. It is possible that the relationship could even be bidierectional, which effectively marries the research findings from both extremes, with infrequenet or acute smoking leading to a reduction in the negative mood affect, while ...

1. Describe the culture of Canada and compare it with India. What are some of the main similarities and differences? Where do you think people from India culture would have problems integrating into Canadian culture? (Use cultural dimensions discussed in class as the basis for your comparison) Canada is a relatively young country, having been discovered by Europeans in the 15th century but only becoming a confederate in 1914. Throughout its history, Canada has been invaded and populated by the French and the British, and has retained very liberal immigration policies, encouraging a mix of European (Dutch, Spanish, Polish, Ukrainian, Swedish, ...

Definition and Causes

Nonalcoholic fatty liver disease is a common cause of chronic liver disease. It arises due to the deposition of fats in the main cells of the liver. The disease ranges from the fatty changes and inflammation in the liver to cirrhosis and fibrosis. Studies suggest that the simple fatty liver is not harmful but the disease can progress and lead to a chronic condition of the liver. The discovery of the existence of the disease is not easy but it may happen through raised liver enzymes. The disease is associated with obesity. Nonalcoholic liver disease is similar to liver disease but ...

Natural selection can be referred to as a process through which biological traits turn either more or less common within a population as a function of the impact of hereditary traits on the differential reproductive victory of organisms’ interaction with their surroundings. It is a major evolution mechanism. Charles Darwin popularized the term natural selection with an intention to have it compared with artificial selection, now referred to as selective breeding.

There exists variation within every organism’s populations. This takes place partly since random mutations happen in the genome of an organism, and these mutations can be acquired by offspring. All ...

Introduction

People are very privileged to witness and experience a profuse and diverse natural resources and wildlife on our planet. However, this abundance of natural resources comes with a big stewardship responsibility. For many years, people have known the moral obligation to conserve and guard the diversity of wildlife. Loss of different species is very common nowadays. This loss is brought by population growth, habitat fragmentation and loss, invasive disease and resource removal (IPCC, 2001). Scientists state that the world is now living the sixth vast extinction. Countless species are in jeopardy. For instance, in the United States, more than five-hundred ...

It is clear from the preceded discussions and illustrations that the technological advancement has resulted to a great change in the political communications system. However, new media is only a means to an end. It cannot create a backlash against government where none previously existed (Megalogenis, 2010). Essentially, modern media does not fabricate information but instead it serves as a platform to disseminate what already exists. Unlike, the traditional media where individuals relied on edited information, new media platforms such as twitter give people autonomy to share information with the highest degree of originality. For example, citizens in the US share information concerning ...

Critical analysis on the demographic status of a target population is very important before unleashing a new product in the market. Demographic analysis indicates the measurements and dynamics of the target population. It can be used in planning business to analyze the population related to the geographic positioning of the business. Basically due to the load the demographic reports are usually subdivided into different categories depending on the specification of the report. An example is the AMA report that is generated from the US census decennial data. However, some of these categories can be subdivided to generate smaller comprehensible categories. ...

Question One

The implementation of the project was faced with a number of ethical issues. The most predominant was assigning personal blame to some of the participants who had been adversely affected by alcohol and substance abuse. The ethical dilemma in this instance was that the health status of many of these individuals was caused by personal choices, for instance the choice to engage in alcohol and substance abuse (Nies & McEwen, 2013). There is a belief that individuals should be blamed personally for illnesses that result from their personal choices (Hernandez, 2011). However, previous discussions have highlighted the influence ...

There just is not enough fresh water in the United States to sustain the current usage rates indefinitely. In America, as in the rest of the World, water reserves are facing a triple threat from a combination of human consumption, agricultural needs and industrial demands that stress our current reserves. Complications from climate change may further intensify these problems. As glaciers melt, they contribute to rising sea levels; they also are a fresh water reserve that is fast dwindling. Although Global measures are being set in place to combat and mitigate the effects of climate change the most effective advances in consumption ...

1. The issue of immigration is a multi-faceted, controversial one. It encompasses issues such as cultural assimilation, human rights and dignity, law and justice, employment, as well as educational opportunities for host countries and migrant countries. For example, some people, like Jonathan Laurence, demand a secular absorption of Muslims -- an unconditional acceptance of their cultural norms by their host countries, and more tolerance for the rapidly-growing Muslim population in European countries. Laurence is an associate professor of political science at Boston College. Kofi Annan, United Nations' Secretary General on International Flows of Humanity, states that we need a more-balanced, conservative approach ...

Belize is a country in Central America that shares coastal borders with Mexico and Guatamala. The capital of the country is called Belmopan. The official language is English. One can be considered poor if his daily expenditure exceeds daily income. Also when one lives on an income which is below a dollar per day, he may be considered poor. However, poverty can also be measured by the number of dependants that one has. Basing on the report about Belize, more than half the population is poor. This means that dependency ratio in this region is high. This trend keeps on increasing. ...

The photomorpogenesis research project at Clemson University is very interesting. Photomorphogenesis means light-mediated growth, and photomorphogenesis research looks at how the manipulation of light sources effects plants. This regulation of plant growth is independent of photosynthesis and it is controlled by the pigment phytochrome. Phytochrome exists in two forms, Pr and Pfr and has peak absorptions at 660nm and 730nm red-range light. It’s the conversion of the pigment between the two forms that ultimately influences the plant growth, the morphology, flowering, and germination.

The photomorphogenesis research program at Clemson University was founded in 1985. The initial research ...

The scope of corporate welfare policies date back to the close of the year 1960 when President Lyndon developed these policies as a means of addressing pertinent issues aligned with income inequalities. Precisely, corporate welfare policies seek to identify families that are distraughtly. This is attained through calculation of the annual budget spent by a family on food. As such, families whose, income is less than three times of their annual food budget are considered poor. In fact, such families are viewed to be in dire need for public assistance (Mattern, 2006). For this purpose, corporate welfare policies require the government ...

Identify a Culturally Diverse Population within Your Community

Attaining cultural competency is one of the major goals of health care institutions in United States. Achieving this goal creates a greater challenge to U.S. health care sector because of the higher numbers of diverse patients and health care providers. Moreover, most health care centers spend time serving diverse populations, which are associated with conflicts and violence among health care providers reducing the nature of patient care offered by medical professionals. Culturally diverse populations suffer high risks of poor physical, social and psychological health and often never get access to quality health care (Galanti, n.d). The following discussion focuses on ...

- Factors in phenotypic variations Factors in phenotypic variation consist of: Variation in phenotype (Vp); Variation in phenotypes caused by genetic variation (Vg); Variation of phenotype caused by environment (Ve); Variation in phenotype caused by interaction of genotype and environment (Vgxe). In addition to the above factors, phenotypic variation is also influenced by effects of genotype on phenotypes.

- Additive genetic variation formula shows that Va is influenced by phenotypes (p), additive (a) and dominance (d). As population evolves, the values of p, a, and d change. Consequently, Va value also changes. Based on the narrow sense heritability formula, change in Va ...

Corridors and Population Dispersion

Part I. Introduction and Review of Relevant Biology

1. Energy transfer becomes inefficient in higher trophic levels in a food chain. Predators utilize more energy in obtaining food than their prey. The number of organisms and the amount of biomass defines energy relationships among organisms in trophic levels. Most top predators are huge in size but their population is lower because there is not enough energy to support a large population of these predators (Odum and Barrett).

2. A population of infinite size is seen less likely to evolve since it would be almost resistant to random fluctuations within the environment. Small populations on the other hand are prone ...

This report was conducted to examine whether people believe that the amount of CO2 emissions is the main cause of climate change. The study found out that a majority of the people believe that the amount of CO2 emissions and human activities such as burning of fossil fuels and deforestation are the main cause of climate change. The responses from the participants were consistent with our hypothesis that a majority of the people believe that CO2 emissions and human activity are the main causes of climate change. This scenario is mainly attributed to education and the amount of information in ...

The elderly population, beyond the age of 65 has tremendously increased, and current projections indicate that this population will continually increase in the coming years. The healthcare settings have not gone free of these changing demographics, and there has been a need to develop policies that cut across all healthcare settings to facilitate quality care for the aging population (Bennett & Flaherty-Robb, 2003). Different literatures have addressed the issue of care for the elderly population in various ways. While many recommendations exist at technical level, the primary idea is that the healthcare sector needs to adopt policies that facilitate quality ...

Age has a biological and social classification. Age distinguishes acceptable behavior for different social groups such as the right to vote and the military enlistment age. The entire course of a human life has different social constructions that occur at different times. The aging population in America occurs due to improvements in life expectancy and advances, in healthcare technology. Schulz (2006) cites that the future projection of the elderly living in Eastern and Western Europe is likely to increase. The regions of Northern America and Oceania will experience an increase in the number of the elderly. The rates of the elderly ...
