6. Below are listed some objects of varying degrees of abstraction. Suggest properties of each of these objects that can be measured by each of the four basic types of scales. There are relatively few pure interval scales found in business research. Almost all text discussions of this scale refer to the example of temperature scales. However‚ some attitude scales such as the Likert and Semantic Differential‚ are claimed to approach interval characteristics. In addition‚ approximate interval scales

outcome (increased class participation). Validity is in four types and these are: Conclusion‚ Construct‚ Internal and external validity. Conclusion validity tries to find out the relationship between a program and the observed outcome. For instance‚ a connection between Re-entry policy and increased failure rate in schools. Construct validity looks at the extent to which a test measures what it claims or intend to measure. Internal validity refers to how well an experiment has been done and the extent

Reliability and Trust in Mobile Ad-hoc NETworks (MANET) are considerable due to their applicability in different situations such as military‚ emergency applications or health care applications. Indeed‚ due to absence of a fixed infrastructure and a central controller‚ providing trust and reliability still is challenge in these networks. Since energy is limited and distributed in MANETs‚ trust and reliability providing (is different from wired systems and it must be reasonable and compatible with

VIBRATION MEASUREMENT In some practical situations‚ it might be difficult to develop a mathematical model of the system and predict its vibration characteristics through an analytical study. In such cases‚ we can use experimental methods to measure the vibration response of the system to a known input. This helps in identifying the system in terms of its mass‚ stiffness‚ and damping. In practice the measurement of vibration becomes necessary for the following reasons: 1. The increasing demands

if policymakers steadfastly adhere to realist precepts‚ they will have to navigate “the unchartered seas of the post-Cold War disorder with a Cold War cartography‚ and blind devotion to realism could compromise their ability to prescribe paths to a more orderly and just system.” (Kegley 1993:141). This paper will demonstrate that this picture of realism is incomplete – realism is not an obsolete theory in contemporary international relations‚ but is indeed relevant - it can be‚ and has been applied

Refractive index measurement is actually a measurement of the speed of light in a medium. The speed of light (usually denoted by c) is 299 792 458 m/s in vacuum. In other media the speed of light is lower than this value‚ and the refractive index‚ R.I.‚ of a medium is a measure of how much the speed of light is reduced in the medium. The refractive index (n) of a medium is defined as the ratio of speed of light in vacuum (c) in to that in the medium (v) The speed of light in a medium depends on

According to Arnold (2005) businesses operate in an uncertain environment and the managers can never know what will happen in the future. The global economy is divided into several situations.The one is low-income countries which CNI per capita of less than $936 and these countries have such serous social‚ political problems and economic that they represent limited opportunities for operations and investment. The next one is lower-middle-income countries which with a CNI per capita between $938

Assess the Validity of the DTM regarding Global population pressure[15] In this Essay I am going to talk about how valid the Demographic Transition Model is. That means whether it is too predictable ‚ old fashioned or if it doesn’t work with every country due to some Factors being left out. It has to be remembered that the DTM is only a model and cannot predict the future. It does give an indication though of what the future birth and death rates may be for an „underdeveloped“ country‚ together with

FAIR VALUE MEASUREMENT 1. The meaning of fair value Fair value is the price that would be received from the sell of an asset or will be paid to transfer a liability in an orderly transaction between the market participants and the measurement date [IFRS‚ 13 – A501]. However in accounting and economics‚ fair value is the rational and unbiased estimate of a possible market price of a good‚ service or an asset. Fair value takes into account many objectives and subjective factors such as: Objective
