RES675, Version 2 - Written Assignment #1 Essay

RES675, Version 2 - Written Assignment #1 - Essay Example Each part is weighed against generally accepted methods for preparing research articles. The review concludes with the author’s thoughts about the research methods depicted in the two articles, citing appropriateness of the methods as well as limitations. Research is the cornerstone of any science. It refers to the systematic and purpose-driven process of attempting to gain knowledge about something. Research processes are often documented in journals, which describes the reason for the research, how the research was conducted and the results of the research or study made. This paper looks into two researches conducted and reviews the documented research process contained in the journal article published by the researchers. The first research article presents research done with postcards and looks into its usage as a souvenir, collectible or a means of communication from 1985 until 1920. The research was conducted by Bjarne Rogan, professor of ethnology and culture history at the University of Oslo, Norway. His article on his postcard research was published in the Cultural Analysis journal in 2005. The article describes the researcher’s purpose for conducting the research using present day postcard collections from the period mentioned above. The researcher wanted to look into other aspects of postcards aside from their picture side where more scholarly researched had been focused on. Reviews of previously published articles and literature on postcards are also used by the researcher in order to determine the reasons for the postcard’s popularity during its time, as well as to trace the development of postcards and the evolution of its design during the period. The second research article presents research regarding consumption of energy drink among college students. The research was conducted by Brenda Malinauskas, Victor Aeby, Reginald Overton, Tracy Aeby, and Kimberly Heidal, all professors at East Carolina University

Technical Description of the Process of Sleep Essay

Technical Description of the Process of Sleep - Essay Example Other equipment used in support with EEG, is one that measures eye movements that is called electrooculogram or EOG. The Electromyogram (EMG) on the other hand measures the muscle tension under the chin of a subject. As stated in Sleep-Information about Sleep, the practice in studying sleep pattern is EEGs, EOGs, and EMGs are recorded simultaneously on a continuous moving chart paper. This then determines the activities of three aspects – the muscle activity, the brain activity, and eye movements. The NREM sleep and REM sleep occurs in a cyclic manner during sleep state (Sleep, Sleep Disorders, and Biological Rhythms. They interchangeably happen to an individual during his sleep. Sleep starts with periods of NREM and then REM. NREM state has four different stages as determined by the frequency and amplitude (brain wave’s magnitude of periodic variation) of the brain activity. The first NREM stage is characterized by very light sleep. NREM Stage 2 has special brain waves called sleep spindles (burst of brain activity visible on an EEG) and K-complexes (brief high-voltage peak in EEG as defined by Wikipedia.org). Stage 3 and 4 of NREM is described by slow brain waves and in Stage 4 of NREM, it is hard to wake the person up. NREM stage 4 is deep sleep and cannot easily be awakened by external factors. During NREM, the muscle activity remains active and body function is the same with the waking state. The difference is that there is no eye movement.
