Research has been done to determine Essay A lot of research has been done to determine whether short-term memory works better in the morning or afternoon. In a study, 16-18-year-olds (sixth form students of Battersea park school) were administered to take part in a word test to assess their short-term memory. Results of this were analyzed. Null Hypothesis: learning in the morning is more effective Alternative hypothesis: learning in the afternoon is more effective. Introduction To learn new things, to store experiences and to adapt to new circumstances these characteristics of the brain enable us the daily survival . This special flexibility of the brain is reached through constant making and breaking contact between nerve cells. Whenever we learn something, the connections between nerve cells, (synapses) change. At this point, the Axon of a nerve cell and the Dendrite of the neighbouring cell meet. The centre for brain research of the medical University of Vienna is currently involved in two researches that contribute to the clarification of the processes in memory. They had tested the article (of researchers at the Harvard Medical School), which is called a key experiment. It was found that a Micro RNA and the accompanying messenger RNA exist at the contact point of synapses. What are Micro- and messenger RNA? It is a different form of the Ribonucleic acid. As a messenger RNA (mRNA), one is already more familiar with for a long time: It functions as a messenger, transports a message of the DNA often, but not always from a gene out of the cell nucleus into the cytoplasm. There the message is translated often, but not always into a protein. One knows micro RNAs for the least in time: They consist only of 21 bases respectively, and they are not translated into proteins. They rather check an mRNA in that they cause or prevent that the mRNA is translated into a protein. So they are regulators. For example just at a synapse, as long as there a micro RNA on a certain mRNA, it is not translated into a protein. If the micro RNA falls away, the protein emerges and the synapse changes its form and also the signal forwarding. In other words we can say that the nerve cell learned something. In the journal of Cell Biology (172, p. 221) Kiebler describes a second factor that is necessary, with a synapse function: Staufen 2: That is a protein that is responsible for the carrying of mRNA along the cell skeleton to the synapse. It brings RNAs to where they are needed. Neurons which are missing the protein Staufen2 have less synapses, and the signal transmission between them is disturbed. An important notice on that, is that Staufen 2 for the education of functioning Synapses is crucial, says Kiebler ( researcher). If what we have learned is forgotten, long-term connections become out of contact of the connection points. German Neurobiologist worked on the correlation between the outgrowing of the connections of cells, the so-called thorns and the building of functioning synapses. In order to be able to follow the outgrowing of thorns, the cells in the near surrounding area of the stimuli were observed using a high resolution two-Photon-microscope. An electron microscope was used in order to review whether the variations in the nerve cells actually led to the origin of new synapses. Within few minutes after the current impulse, the encouraged nerve cells opened the gate to a new discovery. These thin thorns do not grow spontaneously (as they thought), but rather grow towards possible contact partners. Within the first eight hours no piece of information can be exchanged between the newly emerged cell contacts. Not until the following hours it is decides whether a connection remains exist or disappears. For sure, those contacts, that are still available after 24 hours, have fully functioning synapses which can transfer information and have a good chance to exist after several days. Then the reconstruction in the brain is locked evidently. Which parts of the brain remember which type of memory?

Gender and the Internet Essays -- Technology Computers Web Essays

Gender and the Internet The internet can be a very good source of information, but it can also altar information enough to make it unreal. Feminist sites are no exception to this. Many sites in fact use virtual rendering to altar images in addition to text. There are various topics dealing with feminism and issues involving females, some are well approached and others are not. Women do not tend to have the same type of relationship with their automobiles as men do. In Virginia Scharff’s article, â€Å"Femininity and the Electric car†, this relationship between women and cars is explained in depth. Two websites that show how women look at automobiles are, www.womanmotorist.com and www.cybergrrl.com/fun/womenandcars/. www.womanmotorist.com differs in many ways from Scharff’s article, but is a very good website. This site does not directly say that women drive only certain types of cars. Instead it talks about things such as women and professional racing and even has a section on performance cars. In Scharff’s article it mentions that â€Å"It can be roundly stated without fear of contradiction that the times a woman wants to run an electric 30 miles an hour, are few and far between†¦.It is an unnecessarily fast speed for pleasure driving†¦.If the car you select has a maximum speed of 25 miles on the level, it goes quite fast enough.†(Scharff pg 81) On the website the views are different and show how much things have changed from the article. When addressing the female market, automakers are beginning to admit that "women" are not a single, homogeneous market. Until just a few years ago, all women were categorized as "mothers." Now they are seen as generation X-ers, college students, sports car intenders, 8-5ers, baby boom... ....plasticsurgery4u.com/ http://www.ienhance.com/gallery/default.asp http://www.malepregnancy.com http://www.ivf.com Bad Websites: www.cybergrrl.com/fun/womenandcars www.plastic-surgery.net http://www.advancedfertility.com/ivf.htm http://www.ivf.org http://www.ifi.uio.no/~thomas/po/cryobortion.html Morgan, Kathy Pauly. â€Å"Women and the Knife† Sex/Machine.

It will also be linked to experiences in work placements for example, may be at a care home for adults with learning disabilities, and physical disabilities. The five contexts which will be researched are; one to one communication, group communication, multi agency working, multi professional working also communication with professionals. The research will prove that all these different contexts have different methods of communicating with the other person, or people. Furthermore the research will also suggest how to get effective communication in the†¦show more content†¦Another interpersonal skill is multi professional working, it is when professionals from different backgrounds have to work together in order to determine and to meet the needs of the people who use the services. The fact that these professionals are all from many diffe rent backgrounds the communication will need to be formal and carefully planned to avoid barriers to understanding. The main method of communication you may use in a multi professional working context, is oral communication, but they may also use written communication for writing formal letters, requests etc. When communicating with professionals there could always be a risk of misunderstanding because the service users and the professional may both be from different language communities; this is why when communicating you must always check that you are being understood correctly, and the other person must always ask them if they understand what is being said. The communication methods that may be used to communicate with health and social care professionals are; oral communication, written communication and technology may also be used. An example of when written communication is used, is when the professionals are recording what a serviceShow MoreRelatedUnit 1 - P1 Health and Social Care Level 34668 Words   |  19 PagesWelcome To Sailson Care Home Contents ï ¿ ¼Ã¯ ¿ ¼Ã¯ ¿ ¼Ã¯ ¿ ¼Ã¯ ¿ ¼Ã¯ ¿ ¼Ã¯ ¿ ¼Ã¯ ¿ ¼Ã¯ ¿ ¼Ã¯ ¿ ¼Ã¯ ¿ ¼Ã¯ ¿ ¼Ã¯ ¿ ¼ Welcome to Sailson Care Home!
