The factors affectingthe resistance of a wire Essay An investigation into the factors affecting the resistance of a wire Outline: Start with a simple paragraph saying what you are going to do. Factors affecting resistance of a wire: Material, Temperature, Length and Cross-sectional area Material is the same (constantan) and we are trying to keep the temperature constant. (you need to say this) Length and cross sectional areas will be varied. This needs to be done in two separate experiments (Fair Test) Length and cross-sectional area are the independent (input) variables. The dependent variable (output) is the resistance Science (essential). Use a textbook/internet/secondary source to find this information. Say where you found it, it must be relevant to GCSE! Detailed knowledge will get the higher marks. Ohms Law which gives the relationship between the resistance, voltage and current. Give units and equations (show correctly) How resistance is related to length (draw a picture, it can also be used as your prediction). Back it up with an explanation (longer path for electrons) How resistance is related to cross-section (draw a picture, it can also be used as your prediction). Note, there are two plots here! Back up with explanation (more pathways). Prediction: Say what you are doing and use your science to back it up Safety: The experiment should be safe and you will follow safe laboratory practice Equipment: At a glance you might well need: crocodile clips, power supply, voltmeter, ammeter, variable resistor, leads, constantan wire, meter rule, micrometer (to measure wire thickness). Include a circuit diagram. Remember you might need to change equipment after the preliminary experiment. Say what any equipment is used for. Preliminary Experiment: The purpose is to see if your method is suitable to test your prediction, make sure things work and make any changes. You will need to record these results and plot things. Use this information carefully and mention if you make no changes or changes. If the preliminary data looks sensible, then you are on the right track. Repeating Measurements: The same idea as for Chemistry, there needs to be enough different lengths (5 min) and cross-sections (5 min). Measurements need repeating and checking. If a particular set of data is not looking good, discard it and take another measurement. You ideally want 3 sets of similar data! Precision: Voltages, currents, resistances, lengths and wire thickness need to be recorded and presented to the correct level of precision. Say what ranges data will be collected over etc. Data Tables and Plots: Must have clear and correct units, titles, etc. These can be presented using spreadsheets. Plots must be done on graph paper (not computer). Must cover more than half of sheet and have suitable axes. Graphs must be correctly labelled and the points should be crosses drawn in pencil. Best fit-lines should also be shown. Seek help on this if not sure. References: Most likely you found out things, say where you found this information. Fair Test: Absolutely crucial to show. In a fair test you only allow one thing to vary.

Psychoanalytic Case Study of Preston Essay

Preston was concerned over his aggressive behavior towards other males in and outside of the home. He had frequent altercations with his brother, both of whom lived with their parents. Preston was adopted at a very young age. This was a major cause of his recent issues. He feared that his emotions would progressively get worse, and that something detrimental would happen. In accordance with psychoanalysis, Preston was allowed to explore these issues through free association. Preston was shown that his subconscious had been concealing issues related to his early adoption. Preston was shown constructive ways to deal with these issues. Preston continues to make progress in this area, and is exhibiting less signs of his previous issues. Psychoanalytic Case Study of: Preston A Conceptualization and Treatment Plan The individual in this case study presents a multitude of symptoms that are affecting his daily life. The individual has many factors from his childhood that would contribute to these issues. This study goes to show how the subject’s childhood has a direct relationship to the issues that he is currently experiencing. The identification of these issues is necessary in order for treatment to be successfully implemented. Presenting Concerns Preston presents himself as suffering from multiple issues that affect his daily life. He claims to have issues with forming any relationships with other males. He states that he is overtly competitive when dealing with these other males. His biggest issues arise when dealing with his brother. Preston was adopted at a very young age, and has always had issues getting along with this brother. This aggression has moved from just dealing with his brother to all males in general. There have been instances where the police have been involved in altercations that Preston has had at home. He fears that this will continue until he is arrested outside of the home. Preston still lives with both of his adopted parents and his brother. Preston has stated that he is constantly vying for his parents’ attention, and his aggression increases whenever someone else is monopolizing their time. He does not feel that he will always become violent, but that his anxiety is constantly increasing in situations such as this. He is afraid that his frustration and need to outdo others will end very negatively. Case Conceptualization It appears that one of Preston’s main issues is that of Displacement. According to Murdock (2013), this occurs when a subject shows anger towards someone who is less dangerous than the real cause of an issue (p. 40). Preston shows that he has issues in dealing with the fact that he still lives at home with his parents. He verbally abuses those that he sees as â€Å"better† than him. Preston does not wish to abuse himself over this issue. So, he abuses others that he believes will accept the abuse. He seems to blame others for whatever failings he has in life. He takes his frustrations out on whoever is the most convenient to him. This involves rage towards his brother, as well as friends of his parents. The fact that Preston was adopted as such an early age raises the issue of attachment bonds as well. It appears that Preston may have become overly attached to his adopted parents. Much of this may have to do with the way that they raised him. His parents were very protective, and would cater to his every need. This seems to have created a kind of subconscious reliance on his parents, and the need for their constant approval. This leads to the constant need for their attention as well as the need to outdo peers. The aggressiveness towards peers does not seem to have started until Preston was old enough to identify that was adopted. He seemed to be displacing fear that his current parents would abandon him onto others. This is the main subconscious issue that is affecting Preston. His fear of abandonment has caused him to irrationally fear any force outside of his parental relationship, including his brother. This affects his appraisal tendency, which is the way his brain perceives threats and relates to his aggression and depression (Gilbert, 2007, p. 47). This is the disconnect that is causing most of Preston’s issues. He feels threats that just are not there. He remains living with his parents, constantly vigilant of anyone that will take them away from him, including his brother. This has manifested itself in a sort of hyper-masculinity. Preston’s ego identifies no other way to express these abandonment issues other than with aggressiveness. Also, the fact that Preston’s aggression has continued to increase could be directly correlated with his parents aging. Perhaps he fears that not only could people take his parents away, but the fear that death is closing in on them. This could also be manifesting itself in Preston’s fear and frustration. Treatment Plan Goals for Counseling The goal for psychoanalytic therapy is to get Preston in touch with his subconscious. This serves to identify the root causes of his present issues. Preston will need to identify specific defense mechanisms that he created in childhood. The material that has shifted from the subconscious to the conscious will need to be readily identified (Murdock, 2013, p. 37). Once these mechanisms and thoughts are out in the open, it will be easier to discuss them and change present behavior. Interventions The fundamental intervention to employ with Preston will be â€Å"free association†. According to Murdock (2013), free association encourages the client to reveal whatever he is thinking even if it seems irrelevant or offensive (p. 49). This will be particularly helpful for Preston, and can reveal what his thought process is when he has these aggressive bouts. It seems that Preston has not been totally honest with himself. Free association can help him to bring out deep-rooted ideas for analysis and discussion. This intervention can provide logic and reason to the seemingly illogical thoughts he is experiencing. Establishing the Relationship I realized that Preston had issues in dealing with other males. I asked him if he would feel more comfortable dealing with a female counselor. He indicated that he did not react the same way to me as with other males. He stated that he realized that my sole purpose was to help him with his issues, and this made him not feel anxious or aggressive. I relayed that I was glad this was the case, but that I needed to be immediately notified if these sentiments changed. Whenever I felt that Preston was actually getting anxious or aggressive, I made him aware. I explained to him that he was projecting these feelings onto me, and that it was harmful to the counselor/client relationship. He quickly calmed down, and apologized. He seemed to genuinely understand my concern for his well-being. Analysis of Transference The occasions that Preston did display anxiousness/aggressiveness, he did seem to understand that he was doing so after it was brought to his attention. He realized that I was not causing his issues, and I attempted to apply this to his other personal relationships. We would analyze why he was feeling this way, and how it related to his childhood and parents. He came to the conclusion that if he did not get these feelings under control in session, then he was never going to get them under control outside of it. Insight Preston came to realize that he had subconscious issues regarding his adoption as a child. He understood that he was so shocked by learning he was adopted that he was afraid it was going to happen again. He learned that he was very afraid of losing his parents. He acknowledged that his aggressive outbursts were not about the people he was dealing with, but about his fear that his parents would somehow like them better and abandon him. Preston identified that this is not considered normal behavior for someone his age. He picked up various calming techniques, and needed to constantly remind himself that the issue was him, not others. I was able to assist Preston in identifying the root causes of different scenarios and emotions that he discussed. His visible anxiety and aggression seemed to be kept to a minimum. With his understanding of why he was experiencing these emotions, Preston seemed to be doing better in his daily life. He reports being able to hold a discussion with other males without feeling the need to be dominant. He has also taken steps in explaining his fears and issues with his parents. Conclusions The next main milestone for Preston will be to find a home of his own. This will take time and adjustment, but will be a great leap forward. Also, he is noticing some of the same issues he is dealing with in his brother. Hopefully, Preston can persuade his brother to seek the same sort of help that he has received. This will have to be gradual so as to not induce any sort of separation anxiety. However, if Preston continues with treatment and making positive choices, then he will be continuing on the path to recovery.

Analysis of Charlotte Gilman’s Story The Yellow Wallpaper

Charlotte Gilman’s short story â€Å"The Yellow Wallpaper† is centered on the deteriorating psychological condition of the female narrator. As a woman in a male dominating society in the 19th century, the narrator has no control over her life. This persistence eventually evolves into her madness. The insanity is triggered by her change in attitude towards her husband, the emergent obsession with the wallpaper and the projection of herself as the women behind the wallpaper. The â€Å"rest cure† which was prescribed by her physician husband, created the ideal environment for her madness to extend because, it was in her imagination that she had some freedom and control. As the story begins, the narrator’s relationship with John is already erupting. She does not agree that extensive rest is the best thing for her and feels that â€Å"congenial work, with excitement and change,† would be more suitable for her needs. However, she does feel that he knows b est and seems consciously guilty of overlooking it. She informs the reader that â€Å"I have a scheduled prescription for each hour in the day; he takes all care from me, and so I feel basely ungrateful not to value it more† (Gilman 239). These conflicting emotions cause the narrator to have stress. There are times when she wishes she could write in her journal freely, but she knows that John would disapprove and condemn her for it. Writing is her way of expressing feelings and thoughts, but keeps it hidden from John which is tiring.
