Summary of the Topic

Polygamy entails a practice or the state of having more than one marital partner at the same time while monogamy involves sticking to one spouse. Biologists, anthropologists, and archaeologists have been trying to find a solution to the complicated query of whether human beings are polygamous or monogamous. Research teams have reviewed the variations of human DNA to that of animals and have come across several ways to explain the evolution of people from a polygamous setup to one that requires more intimacy. This essay assesses articles and books that attempt to understand how evolution has affected polygamy and ...

Mental Health Issues Influencing Academic Performance amongst Students in Australia

It is in the nation’s best interest that youth complete as high a level of education as they are capable because dropping out of school can greatly diminish an individual’s chances in life and the ability to contribute to the community. Indeed, participation in tertiary education promotes national economy and innovation (Wierenga, Landstedt, & Wyn 2013, p. 3). The factors that compromise a young person’s ability to obtain a tertiary level education are socioeconomic disadvantage, rural location, and being an indigenous Australian (Wierenga, Landstedt & Wyn 2013, p. 4). Stafford, et al. (2007, Mental Health, para. 1) define ...

Thermal conductivity is defined as a material’s property to conduct heat. Heat transfer across materials occurs in materials that have lower thermal conductivity and transfers faster in materials with high conductivity. It is important to determine the thermal conductivity of materials since different materials are used for different applications. For instance, materials with high conductivity are more efficient when they are used as heat sinks since they can conduct heat away faster. Those with lower thermal conductivity are often used as insulators (Callister 78). The classical transfer of energy happens through conduction, radiation, convection or combination of all ...

Abstract

Language is a system of transmitting views and expressing ideas in form of speech or in written forms. The vocabulary of any language is a lexicon and it is serves as a connection between a sign and its meaning in any language. Therefore language is divided in three parts: signs, meaning, and a code connecting signs and meanings. In any Language there are four levels which are used to analyse the language. These levels are: Phonology which analyses sounds; Morphology which analyses units forming a language structure; Syntax which analyses rules and principles in forming sentences; and Semantics which analyses the relationship between signs and ...
