ANALYSIS OF A TRADING EXPERIMENT

Analysis of a Trading Experiment
Today, many fields have professionals that provide expertise and guidance whenever people need to make decisions. Such professionals offer technical advice because of the nature of knowledge they have in a specific field. The knowledge is not common to all people hence they rely on professional advice to make their decisions, an element that determines their success in whatever they are doing. In some cases, people have to weigh their decisions against the advice given by professionals because they may not necessarily agree with the perceptions of the professionals (Spencer 2009). Similar to the 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...

Byzantine art is a general name which is used to describe the artistic products which come from the Eastern Roman Empire, which is sometimes known as the Byzantine, as well those which come from the nations and states which were culturally inherited from the empire. These products were mainly Christian-oriented art even though derived from techniques and forms of Greece and Egypt. This style spread to all other corners of the empire, even in places where the orthodox Christianity was flourishing (Evans &William, 2).
The style that characterized the Byzantine art was one which was almost concerned with the Continue reading...

Birds' surveys are used to give reliable approximate or index of the size of the population of a definite species due to various reasons within a given area (Gitzen 2012). Birds' surveys are often conducted to assess habitats for suitability to support breeding and at times wintering birds species and record incidental bird citing during visits. Special emphasis is often placed on the suitability of the site for given species and due to conservation concerns. After an initial assessment, further surveys may be required for obtaining detailed account of birds species of birds and communities in key habitats areas. Continue reading...

(1.1) This experiment is about determining the effect of angle of inclination in the acceleration of an object. The independent variable is the angle of inclination of the slope of motion; the dependent variable is the acceleration of the object.

Hypothesis

(1.2) The angle of inclination of the slope is directly proportional to the acceleration of the object. Without initial applied force, the only acceleration of the object would only be due to gravity. Thus, the relationship will follow the equation:
a=gsinθ
Where a is the acceleration of the object, g is acceleration due to gravity, and θ is the angle Continue reading...

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...

Critiquing Quantitative and Qualitative Studies

Several research techniques are available all with the aim of achieving precise data or information or data about something. Quantitative technique, sometimes referred to as true science, involves the use of mathematical and statistical methods in the analysis and drawing useful information from a specific set of data (Davies, 2009). On the other hand, qualitative is a type of technique used to study behavior and habits portrayed by humans under different environments. The critique is aimed at juxtaposing the two techniques involved in the field of research with critical analysis of the two methods.

Lack of Equipment Failure and Potential Resolution
A major problem within a clinical trial is an equipment failure. In a clinical trial related to cardiovascular diseases, Electrocardiogram (ECG) is a major equipment used to study particular heart defects. Failure or inaccuracy of the equipment may lead to improper treatment or even lead to fatal issue and death in rare cases. EKG readings form the basis for interpretation of a particular hear defect. ECG is required for detecting electrical activity in the heart, this in turn if not functioning properly may produce inaccurate results. ECG malfunctioning was reported due to Continue reading...

Floating point is a numerical-interpretation system in which strings of digits or bits represent real numbers. A system of arithmetic is defined to permit these representations to be manipulated with resultant being similar to the arithmetic operations done over real numbers. The representation uses an explicit designation of where the radix point should be located relative to the string. In computing, fixed-point number representation is a real data type representing a number with a fixed number of digits before and after the radix. The most common way of representing floating-point numbers in computers is the IEEE 754 standards or Continue reading...

Technological applications have had an impact on almost all sectors of the economy. The same changes have equally pervaded the area of criminology and criminal behavior in general. Crime has become increasingly complex given the advancement in weaponry. In addition, the juvenile nature of the law on modern forms of crime has made some crimes pass out as legal activities chiefly because of the silence of the law on such like crimes. This makes it difficult in the overall to analyze criminal behavior on the context of weapons technology. The brief of this paper shall be to discuss the 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...

Part I

A comprehensive justification of the federal grant system is that it provides a measure of service about the national interest. Every grant from the federal government to all sectors serves the same purpose. It is only difficult to assess the matters of national concern since they are many. I think the federal works by stimulating the state and local authorities in the fields of national interest to ascertain the proper use of the financial aid. America does not have new grants of national expenditure with the exception of civil defense. The inherent powers provide for the development Continue reading...

Automation is a technology that entails the use of sophisticated machines in performing tasks .In this regard, the tasks may be those that are fundamental in the manufacturing industries, production industries, processing and attributed to other instances that largely recognize the use of skilled labor. Examples of automation in industries include the use of computers. On the same note, some countries recognize the use of robots as a substitute to human labor.
