Experimental Design Assignment Essay Example Experimental Design Assignment Essay Experimental Design Assignment Essay The household product that we used was 5% ammonia. Ammonia is a chemical compound composed of nitrogen and hydrogen, with a formula of NH. Nitrogen is one of the main ingredients commercial agriculture, industrial manufacturing, and household cleaning products. It can be used to clean floors, rugs, tubs, silver, ovens, and crystal. However, after using the ammonia as a cleaning agent, it is washed away with water, flowing into the sewer system and into the environment, where it can affect other living organisms. According to Ammonia concentration determines differential growth of ammonia- oxidize arches and bacteria in soil microcosms, the proportion of ammonia into soil will affect the ecological niches for plants. After a certain proportion of ammonia to soil, the ammonia will create an environment where it is difficult for any plant to grow. Thus, the purpose of this experiment is to determine the concentration of ammonia at which the niche for plants to grow. Hypothesis Ammonia proportion of egg of soil to 30 ml of ammonia would not destroy the lands niche. There will be no difference between the control group and the group with 30 ml of ammonia. Methodology: In order to test the null hypothesis, first we measurements of soil in a beaker without any ammonia and equally divided the soil into 3 plant containers. In each plant container 5 seeds were added. This group was labeled as our control group. Then, 10 ml of ammonia was added to another beaker of egg soil and it was again equally divided into 3 other plant containers. Each of these containers was filled with 5 seeds as well. This second group was labeled as our 1% concentration group. The labeled as 2%, 3%, and 4% concentration respectively. For this whole process, we had 15 different containers in total. After 14 days, the results were collected. First, grown plants from each plant container in the control group were cut its base, measured and weighted. Then the mean of the heights and weights was calculated for this group. The same process was repeated consequently for 1%, 2% 3% and 4% labeled grouped concentration. Results Figure 1 Figure 1 shows the mean of the mean for each group. From the control group to 10 ml of ammonia, there was a 998% decrease in the weigh of plants and 100% decrease in the growth of plants from 10 ml to 20 ml. There was no grew in the plants after 20 ml. Figure 2 Figure 2 shows the weights of plants in each group. There was a 680% decrease in the weight of the plants from the control to 10 ml of ammonia and 100% decrease from 10 ml to 20 ml. After 10 ml of ammonia, there was no more growth in plants. Discussion In this experiment, there was no growth after 10 ml of ammonia. Since we made the incineration too high it was difficult to test our null hypothesis using the t-test analysis. Our results clearly show that any proportion of egg of soil to more than 10 ml of ammonia will be very harmful to the niche for plants. In the future, proportions of egg of soil to 1 ml-10 ml of ammonia could be used to test to see the correct niche of ammonia for plants, as weve seen in this experiment that small amount ammonia could be helpful for farmers. Given the results from our experiment, the usage of household ammonia does affect our environment. Same result will be true for other household antibacterial or detergent products which might be beneficial to us in some cases but are very harmful to the overall environment. The government should regulate the excessive misuse of these environmental contaminates so that we all will be protected from a long term negative effects of environmental changes.

Economics Of Industry - Essay Example Some of the factors which can define the decision making process of whether to buy or outsource also depend upon the agency relationship. Bergmann and Friedl (2008) are of the view that since managers have the private information regarding the projects therefore they intend to exert "unobservable levels of different kinds of effort in order to increase the feasibility of successfully completing the project in terms of meeting product specifications." (Bergmann and Friedl). This paper will attempt to present a comprehensive analysis of the above factors and their impact on the decision making process of whether to buy or outsource. Further, this work will also attempt to present what remedies may be available to address such problems in terms of agency cost. To make or buy is one of the fundamental dilemmas faced by the modern organizations as increasing competition and globalization is forcing organizations to re-evaluate their strategies as well as processes and technologies to better position themselves onto the competitive landscape. As discussed above that the decision to make or buy depends largely upon whether the organization is willing to refocus its strengths on exploiting its core competencies and outsource some of the activities which do not probably fall under the domain of their specialty therefore instead of developing weaknesses into strengths, organizations often consider to focus on their strengths. Secondly, lack of internal resources such as manpower, technology, economies of scales etc may force organizations to decide on buying rather than producing in house. Thirdly, cost reduction is another critical element which contributes in deciding whether to buy or make because due to lack expertise, lack of resources, org anizations may find it expensive to produce in house and rather focus on outsourcing. However, despite all these factors, there are some other critical elements which contribute to that decision making process. As discussed above that uncertainty is one of the key elements which differentiate the labor markets therefore both internal as well as external factors heavily influence the decision making process of make or buy. Internal organizational factors such as agency relationships as well as adverse selection involve the management of the firms however; uncertainty and asymmetric information may be internal as well as external in nature. Agency Relationship Diversification is one of the reasons why managers often decide to make investments so that the risk could be easily distributed across the different products as well as markets. It is also because of this reason that the managers often have to decide whether to initiate that diversification process by producing that product or procuring that machinery in-house or outsource them. However, Denis et al (1997) are of the view that there is a negative relationship between the diversification and the managerial equity ownership. (Denis, Denis and Sarin) This fact also points towards the tendency of the managers to perform in ways which create a sort of value reducing diversification for firms. Therefore taking an analogy from this fact, it can easily be inferred that while making

Managing diversity gender (HRM) - Essay Example Instead, it should be understood for the company's growth and development in terms of management and productivity. It is a common knowledge that every human being is born unique from one another. But sometimes, there are common attitude that people share. Most men projects authority over the other gender is an example. There are certain business organizations, such as technical and industrial companies, that men are the usual individual to have an executive position or even the job itself . This group believes that it is odd to have women working in these fields. Because of this, said industries are having difficulties in keeping and hiring female workers (Weiss n.d.). In his article, Managing Gender Diversity: Five Secrets for a Manager's Toolkit, Weiss cited a research study by Louann Brizendine on how men and women faces the environment they are working on. According to Brizendine, men and women react accordingly based on how their brain processes information, what their intuition is saying, how they feel, their intention in communicating and anger management. Women's brain works, first, by identifying the faces of the people around them while men are more on scanning their environment. This is the reason why women are more capable of sensing other people's emotion than men. Most women also trust in their gut feeling than men.

High School Reunions Essay Example for Free

High School Reunions Essay An observation of a high school re-union was followed by an interview with two of the people attending for this ethnography. The two attendees used for the interview were one male and one female. After identifying some of the possible rationales regarding the culture of the reunion in the observation, the interview was conducted on the basis of the rationales. This was then analysed and compared to some of the findings from cultural research and theory before a conclusion of sorts was made. Observation The group environment and context for the observation was that of the Aliso Niguel High School Class Reunion, Class of 1999. The High School is located in Aliso Niguel CA. The reunion being observed took place in Irvine, CA. There were approximately 300 people present. The general patterns of behaviours amongst the people consisted of lots of mingling and idle chat. Some of the people were notably more reserved than others. It seemed as though the single people were working harder to start conversation and were far more approachable. In contrast, couples didn’t seem to portray the same type of inviting body language when on their own, but became more confident when with a spouse or friend. Approximately, 80% of the attendees held drinks in their hand as a norm and there were also presents and cards being exchanged from the outset. From overhearing the participant’s conversation it seemed as though many of them still lived in the Southern California area and this became a main source of conversation throughout. The interaction was generally based upon excitement, smiling and heightened voices at notably louder than normal volume. With regards to dress codes, there didn’t seem to be much evidence of diversity. This was particularly notable in the case of the females. The majority of them had light hair past their shoulders and the clothing style that was adopted by the attendees was strikingly similar. There were very few obese or overweight people that attended. These people perhaps did not attend as failed invites were not taken. There were clear indications of sub-groups at the gathering, although they seemed to carry conversation with the rest of the attendees in accordance with the larger group. Amongst the males there were indications of many stereotypes such as â€Å"meat head† or â€Å"gym jocks†, as I overheard one female state. Although as many of these people are now approx. 27-30 years old, it was harder to categorize them in such terms. There did seem to be a stronger merge between coupled groups and singled groups rather than any cross over. There appeared to be a symbol of people trying to meet a certain criteria throughout. For instance, there was a group of approximately 15 females. I overheard that all of them got married within the last 2 years and many of them either attended and/or where present at each other’s wedding. This could be indicative of a desire to follow patterns and trends in behaviour as though as everyone else is getting married then so must they, so that they aren’t left behind. Contrastingly, the males seemed to compare status in relation to possessions, such as career, cars, and houses paying particular attention to the location of the houses. There appeared to be a great deal of stereotypical role playing. This was perhaps due to the situation and the fact that earlier identities were known by other attendees. Expectation of success may have accentuated the desire for the attendees to exaggerate their status so as to appear successful. I felt that many of the attendees really liked re-living the past. They may have either really enjoyed their high school years, or were very curious as to what their classmates were doing now. However, this could also be a test of identity or serve as a self measuring experience on the basis of their peer’s behaviours and successes. Interviews The questions that I asked were qualitative, semi structured and thematic in nature focusing mainly upon stereotypes and reasoning. This was to see if the thoughts of the interviewees compared with what seemed apparent about the culture of the re-union gathered from the observation. That is to say, was this something of a self regulation exercise for the attendees or was it an exercise in cultural normality? On being asked for their reasoning in relation to the re-union, the male interviewee stated that: ‘No one takes it seriously. Certainly not me. ’ The second female interviewee stated in relation to the same question that: ‘You kinda get to know everyone personally again‘. These responses suggested two different rationales. In the case of the male, it appeared as though the reunion was something of a casual affair that could turn out to be fun as long as it wasn’t taken seriously or that anything was invested in the occasion. Whereas the female’s response indicated that there was a personal form of intimate gratification involved in seeing other people again. The latter response would suggest that there is some form of self regulation going on in relation to peers (Devine, 1989). Whether this was merely for the purposes of satisfying interest or to measure oneself against the progress of other peers was less clear (Tajfel, 1982). On being given and questioned about some of the stereotypes of others observed at the re-union, the male interviewee stated that: ‘The stereotypes you have mentioned are generally applied to people you haven’t interacted with. They’re based upon ignorance. They go away once you get talking’ This indicates a difference between known and unknown people, which is common in western individualistic society (Hofstede, 2001). It appeared that the male attendee was not willing to accept or perhaps did not realise the significance of stereotypical role playing and instead took everyone at face value once a conversation took place with another. This rejection of stereotypes was also found in the response of the female attendee who stated that: ‘I don‘t really know, I always talk to people at parties and they always seem friendly, bar one or two. Is that a stereotype? †¦ha ha! ’ This raised some interesting points. For instance, although the attendee may well have pre-conceived notions about certain stereotypes, the individuals may have felt that they were the only people that perceived them in that way (Devine, 1989). Due to the experience of the situation that reinforced certain social norms, this stereotype may diminish or grow regardless of the former social group. This was put forward by Gudykunst, who suggested that, â€Å"Some of our stereotypes are unique and based on our individual experiences, but some are shared with other members of our in-groups. The stereotypes we share with others are our social stereotypes. We may know what the social stereotype of a group is, but still hold a different view of the group. † (Gudykunst, 1997, p127) On asking about what they felt they had gained from the experience of the re-union and what others may have also gained, the male attendee stated that: ‘I found out all the different directions that people have taken. It’s not just about getting married, buying a house and having kids. Most people have branched right out since then’ The second female attendee stated in relation to the same question that: ‘I feel good that everyone seems to be doing so well. Everyone’s the same, but do their thing differently, if you know what I mean’ The notion of difference was clear in the responses of the interviewees. It would appear that although the roles and social norms were fairly similar and the content of the conversations were uniformly based upon success, the overview was based upon everyone’s success and happiness maintained through a degree of different life styles. This was again perhaps unsurprising given the individuality that is so common to western cultures (Hofstede, 2001). The emphasis on success and progression was also unsurprising for similar reasons. However, the amount of actual difference that was displayed at the re-union in terms of dress code and normative behaviour could be seen in contradiction of this difference (Tajfel, 1982). It would appear that such difference was only referred to in conversation rather than in actual behaviour. It would appear that sub-cultures were compromised at the re-union and stereotypes were overlooked as long as the attendees followed the correct social norms whilst at the re-union.

Brave New World - Technology :: Brave New World

Brave New World - Technology    Technology, what is it? It’s usually something new, and better than the old idea. Technology started with cars, stoves, TV, radios, etc. Cars takes somebody from one place to another, faster than walking, running, or biking and one could go places without getting tired. Stoves allowed one to conveniently be able to turn on and off heat to a cooking utensil with less clean up. The biggest contributor to making our lives easier would be computers, which has come a long way since its introduction to the world. Also, computers have the ability to be improved more, and more in time. In general, technology started off by comforting our lives. Now, the rapid growth of technology has replaced the need for one’s own intellect.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   To begin with, technology makes us lazy. One no longer writes with pen and paper, or a typewriter, but with a computer program. The use of a computer program eliminates many things such as a rough draft. Because one can make mistakes, fix it without a mess, and then print a final copy, a rough copy is not made. It is also not needed according to these people, yet as many people know, spur of the moment thinking is not nearly as good as a well thought out plan. Therefore, a rough copy is much better to have, even though most people don’t make a rough copy because they’re too lazy. This lethargy is due to the advanced technology of computers. Also, almost all programs are equipped with a spell-check. Spell-check is, in other words, a dictionary without the definition. So, because of spell-check, one wouldn’t need to use the dictionary, or is it one would be too lazy to use the dictionary? The use of the internet is also used to cheat. People can look for something to plagiarize across the whole world in less than five minutes. These lazy people just cannot resist this temptation.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   This leads me to my next point, with the use of technology, one no longer exercises their mind. Take the spell check for instance, since one has spell check, they don’t look up words in the dictionary. Spell check, though, doesn’t have definitions, and their might be some replacement words that don’t have the same meaning as the word in your sentence.

Psychological Disorders Essay

1. Does Katherine’s description meet the clinical criteria for a panic attack? Substantiate your  answer. A panic attack is described as an unexpected period wherein the person suffers intense fear that occurs without warning or any reason.   It is characterized by shortness of breath, palpitations, chest discomfort, trembling, choking feeling, intense sweating, nausea, dizziness, feelings of being detached from oneself, fear of going crazy, dying fears, numbness, and cold or hot flashes.   For an episode to be considered a panic attack, the person has to meet four of the symptoms.   In Katherine’s case, she described four of the symptoms to having a panic attack.   She said that she felt dizzy, had difficulty breathing, was feeling nauseous, and felt like she was detached from herself.   From this, I believe Katherine had a panic attack. 2. Does Katherine meet the criteria for a dissociative disorder? Explain. Dissociative disorders are related to anxiety disorders in the sense that they are also reactions to stress and anxiety factors.   A dissociative person often exhibits changes or losses in consciousness, memory, identity or environmental perception.   In this case, the anxiety factor is clearly the visit to the parents’ house.   For some unknown reason, the visit awakened buried memories.   Although Katherine did not exhibit memory loss or shift, she experienced a change of perception in her environment. Based on how Katherine described her symptoms, I believe she’s suffering from a dissociative disorder.   Although Katherine does not display the usual memory loss and split  personality symptoms typical of dissociative disorders, she has, however, described that she felt  separated from her physical self, like she was outside looking in.   She said that even if she was aware of driving the car, Katherine also felt like a different being who was just looking at another being driving the car.   This seems to be a case of Depersonalization disorder. 3. What other disorders does Katherine appear to have? Analyze. It’s not clear whether Katherine was abused at a young age.   But based from the way Katherine pictured her father coming up from behind her to assault her, it would seem that a similar event had occurred to her in the past.   Either her father did the same to her as a child, or a man who resembles her father or has qualities similar to her father had done the same to her.   As a result Katherine developed an acute stress disorder long after the traumatic event occurred. She went into panic on her way to her parents’ house.   Apparently, the drive to her parents triggered unpleasant feelings.   Perhaps the assault on her person happened in her parents’ house or in the nearby vicinity.   Her avoidance of her parents, her admission of feeling estranged from them, and not letting them know about her plans support this assumption.   Katherine uses avoidance to keep the panic attack at bay.   Her avoidance is typical of others who are suffering from acute stress disorder.   Katherine’s troubled sleep, irritability, and nightmares are the result of a traumatic event that she probably has buried in her consciousness.
