Introduction

Accurate and precise measurements are of uttermost importance to chemists everywhere. A measurement is said to be accurate when it is very close to the accepted value. A precise measurement is one in which repeated measures yields values or figures that are very close to one another. However, not all measuring instruments have an equal ability to give accurate and precise measurements. In any given experiment, the techniques and the equipment used to collect data should essentially be of the same precision. In the course of an experiment, there are bound to be less precise measurements and it these Continue reading...

Precision Medicine According to Christensen

Precision Medicine according to Christensen is basically a disruptive solution for healthcare, which means that provision of care for diseases whose causes are understood can precisely be diagnosed and can therefore be treated with predictably effective rules-based therapies. In this case, genomics play a major role. Collectively, Precision medicine is characterized by three fundamental features: the ability to detect casual factors, an understanding of what actually causes a disease and the ability to treat root causes of the diseases effectively (Carey 50).

Determination of the sample size is informed by knowing various factors. These factors comprise of the effect size which entails the difference that exists between two groups under consideration; for continuous data, the standard deviation of the population should be determined. Another factor is the experiment’s desired power for detection of the hypothesized effect and lastly the stated significance level determines the sample size (Dimitris & Aitken, 2009). The last two factors are generally fixed conventionally while the first two are specific to a certain experiment. The enormity of the effect to be detected by the investigator ought to Continue reading...

Non-Parametric or T-tests

Assessment of Non-Parametric
This author will provide an assessment of non-parametric analog. Non-parametric methods don’t demand the researcher to formulate distributional assumptions concerning data. Secondly, nonparametric data uses qualitative methods as opposed to quantitative methods. These are the identified and defined procedures of statistics, which are used to test the hypothesis. They, therefore, don’tneed a normal distribution since they are ranks and count-based (Plichta& Kelvin, 2013). The two non-parametric tests used in the article are the Pearson’s Chi squared test for the nominal/ordinal data and the non-parametric Mann-Whitney’s U-test for continuous variables. Unlike the parametric Continue reading...

William Carlos Williams

William Carlos Williams has always been known as an experimenter, an innovator, a revolutionary figure in American poetry. Yet in comparison to artists of his own time who sought a new environment for creativity as expatriates in Europe, Williams lived a remarkably conventional life. A doctor for more than forty years serving the New Jersey town of Rutherford, he relied on his patients, the America around him, and his own ebullient imagination to create a distinctively American verse. Often domestic in focus and "remarkable for its empathy, sympathy, its muscular and emotional identification with its subjects," Williams's poetry is Continue reading...

Employability and Developing the Self

In the current times, college and university graduates experience a shortcut of employment opportunities, which, according to labor market analysts is generated by both the economic condition but also by the lack of preparedness of the graduates for the available positions (Rao, 2010; Yorke, 2004). The preparedness for getting an employment, securing it and moving ahead to new employments based on deployed skills implies possessing a set of skills, attributes or personal competences, which define the employability (Perozzi, 2009; Yorke, 2004).
Rao (2010) suggests that the employability reflects the graduates’ soft skills, rather than their hard skills, observing that Continue reading...

Management

Module 1 – SLP
Mission and Vision statements defines an organization’s core values and are often used as the guiding principles in establishing organizational objectives. However, more and more companies have a discombobulated notion about the role of the mission and vision statement resulting to a creation of a rather more confusing jargon. What constitutes a good mission and vision statement according to Welch and Welch (2008) should convey a clear definition of realistic and more achievable expectations. Mission and Vision statements should possess specific elements that define the universal values of an organization.

The key elements that an explicitly constructed mission statement that demonstrates definition of an organization’s priorities are:

- Specific aim - Organizations Continue reading...

Introduction

In the past, agricultural production has relied on traditional approaches to enhancing farm production. For instance, farmers in the past used conventional approach such as the migration of birds to determine the climate conditions that were approaching. According to Zhang and Pierce (2013), farmers made planting decisions based on their experiences relating to the climatic conditions. However, traditional approaches to farming have severely resulted to a decrease in output because of the different and varying conditions that are beyond the comprehension of human experiences. As such, sensors have been developed for application in crop and animal faring with the Continue reading...

Philosophy

Historians and scientists play an extremely significant role in society. While the former is concerned with activities that happened in the past, the latter not only seeks to predict with a particular amount of precision what is likely to happen in the future, but also seeks to influence this opportunities. These two activities lead to the collection of two sets of facts. These facts undergo probability tests and analyses whereby inferences are made. Indeed, logic is significant to determine which prepositions are true and which are false. There are usually two sets of truth presented by these phenomena. This Continue reading...
