Theoretical framework 2.1 Introduction This chapter entails the theories and terminologies used by the proponents to build and design the computerized system. A theoretical framework is a collection of interrelated concepts. A theoretical framework consists of concepts together with their definitions and existing theories that are used for your particular study. The Theoretical Framework must demonstrate an understanding of theories and concepts that are relevant to the topic of the research

Adrienne Perry Department of Psychology‚ York University‚ Downsview‚ ON‚ and TRE-ADD Program‚ Thistletown Regional Centre‚ Etobicoke‚ ON Abstract This paper presents a theoretical model for understanding stress and related issues in families of children with developmental disabilities (DD). It first describes the theoretical underpinnings in the literature on stress and coping in individuals and on family stress. The proposed model includes Stressors (Child Characteristics and Other Life Stressors)

Chemical Reactions and Equations Chemical Reaction: The transformation of chemical substance into another chemical substance is known as Chemical Reaction. For example: rusting of iron‚ setting of milk into curd‚ digestion of food‚ respiration‚ etc. In chemical reaction new substance is formed which is completely different in properties from the original substance‚ so in a chemical reaction chemical change takes place. Following are the signs of chemical reaction: (a) Change of state of substance

Systems of linear equations‚ or a set of equations with two or more variables‚ are an essential part of finding solutions with only limited information‚ which happens to be exactly what algebra is. As a required part of any algebra student’s life‚ it is best to understand how they work‚ not only so an acceptable grade is received‚ but also so one day the systems can be used to actually find desired information with ease. There are three main methods of defining a system of linear equations. One way is

Band broadening theory (Van Deemter equation) It is well recognized now that column band broadening originates from three main sources: 1. multiple path of an analyte through the column packing; 2. molecular diffusion; 3. effect of mass transfer between phases. In 1956 J.J. Van Deemter introduced the equation which combined all three sources and represented them as the dependence of the theoretical plate height (HETP) on the mobile phase linear velocity. Originally‚ it was introduced for gas

Balanced Bipolarity‚ Balanced Multipolarity & Unbalanced Multipolarity Introduction I agree with the quote that “Wars between states can be explained by the distribution of power and capabilities in the international system.” Power distribution among all the great powers plays an important role for the stability and economy of the state. I believe that war determines who will govern the international system‚ and whose interests will be primarily served by the new international order
