Atwood deliberately uses preposition before the name of the commander in charge “Offred” to create a new identity so that they can fulfil the new function in the forceful regime....

It has been widely recognised in the language teaching profession that learners need not just knowledge and skill in the grammar of a language but also the ability to use the language in socially and culturally appropriate ways (Byram, Gribkova, Starkey, 2002). Hence the National Curriculum in England underlines the importance of “liberating learners from insularity” (DfE, 2014) and familiarising them with the target culture through a “variety of authentic resources” (DfE, 2014) such as stories, poems and songs. In...

The reuptake of dopamine within the brain is initiated by proteins referred to as “Dopamine Transporters” (DAT) found in-between neurons. DAT act on the pre-synaptic neurons nerve endings and allows them to absorb the dopamine neurotransmitter, thus terminating the transmission of a message. The reuptake and regulation of dopamine results in a steady and level headed mental state. Dopamine as a molecule is a monoamine neurotransmitter, a term that refers to its chemical structure and the fact that it derives...

Introduction This paper is going to discuss the use of impoliteness in the YouTube comments of a video advertisement. Impoliteness can be best summarised as behaviour that is face-aggravating in a particular context (Locher & Bousfield, 2008). YouTube is an online platform where users can post and comment on videos with a user-name. Impoliteness is arguably greater in computer mediated discourse because of the anonymity that the internet and such user-names can provide. According to Suler (2004) when people can...

Introduction A recurring debate in scientific research is the effect of theory-laden observations. Scientific observation is regarded as theory-laden when one’s beliefs, assumptions, or expectations are used to interpret observations. When investigators observe a distant world, everything that their senses convey is interpreted by the observer through cognitive processes that consider their prior training, cultural factors, and environment. In this way, the investigator tries to identify and organize the impression based on prior knowledge and preconceptions. In his scientific structure...

Streptococci species are commonly isolated on Blood agar, a commonly used media in microbiology laboratories. Blood agar is composed of Tryptic Soy mixed with 5% of sheep red blood cells. This media is not only used to isolate streptococci, but also staphylococci species of bacteria via hemolysis which refers to the breakdown of red blood cells in enriched agar base surrounding bacterial colonies (Gera and McIver 2013). The haemolytic properties of blood agar detect Streptococci bacteria. The process is mediated...

As it has been claimed by Agheyisi and Fishman (1970), language attitudes have been the most indispensable concept in sociolinguistics. Ryan (1982) has defined attitude as “a learned disposition to think, feel and behave toward a person or a class of objects in a particular way”. This interpretation emphasizes the positive and negative emotional responses that attitude embodies, and thus, language attitudes consist of an affective component, and extend to thought and behavior as well. In addition to this, Oppenheim...

Ferdinand de Saussure (1857-1913), he is considered one of the founding members of 20th century linguistics as well as being one of forefathers of semiotics. Another developer who helped established necessary moments within the difficult and detrimental beginning stages of semiotics, American philosopher Charles Sanders Peirce (1839-1914) and then later on Charles William Morris (1901-1979), these two American philosophers managed to help hone, what is known as, behaviourist semiotics. Behavioural semiotics is based upon the behavioural theory of signs, this...

Comparing the protein concentration of unstimulated and stimulated tears, the data displayed an equal variance with a T test P-value of 0.224. The P-value signifies there was no significant difference in protein concentration between stimulated and unstimulated tears. Fullard and Snyder (1990) concluded eight out the twelve proteins of tear concentration were found to be significantly higher in unstimulated tears compared with that of stimulated tears. These proteins found to be higher were IgA, IgA-SC, IgA1, IgA2, IgM, IgG, Transferrin,...

A gene is a nucleotide sequence which dictates the synthesis of a particular RNA or protein molecule. Their control over the produced proteins govern both phenotypical and genetic traits, including susceptibility to diseases like Cystic Fibrosis. Driving gene expression is Central Dogma, a two-step process in which DNA is converted to an intermediate RNA (mRNA) through transcription, then from mRNA to protein through translation. Virtually all living and acellular beings abide to Central Dogma bar the Retrovirus family and viruses...
