. I once became a target of prejudice based on my race. This happened shortly after my arrival in the U.S.U.S. from Asia to pursue my bachelor’s degree. I was walking on a street in Washington, DC, with a friend, a U.S.U.S. citizen by birth. What baffled me was the way two young ladies were staring at me. At first, I thought they knew me or that they were confusing me for someone else. However, I later realized that this was not the case as one of them murmured, “look at that dwarf man.” This was about my height as I was p, probably much shorter than the average American man. It is then that one of them came and asked me “are you a Chines” Yes, I replied. She then began to measure how tall I was using a tape measure that she was carrying. Before she could finish her business, she burst into loud laughter and stated emphatically that I am an authentic Chinese.

The ladies’ comments came not because I am too short, but due to the notion and prejudice they have against the Chinese. They believe that all Chinese are short. They thus stereotype any Chinese they come across. This was not the end of the experience. After going back to the residential quarters where we lived, a young man came along and called me ‘a photocopy.’ It was so shocking because, at first, I thought he wanted to photocopy some of the papers he held in his hands. However, it was later that I realized that I was stereotyped. This is after a particular friend of mine who is an American told me that U.S.U.S. people consider anybody from China as a ‘photocopy’ since they perceive products from China not to be authentic.

Indeed, I felt terrible about all the incidences. This is so because the comments were all negative. For instance, how can someone be called a dwarf based solely on the belief that all Chinese nationals are short? Being short is natural, and no one, I believe, determined how black, white, fast, or tall they would be. However, all these are biological

“accidents” that no one chooses. Furthermore, being stereotyped as a ‘photocopy’ is not something good at all. This is because not all Chinese products are fake as the stereotype, I experienced in the U.S.U.S. suggests.

The retention time is the amount of time it takes for the analyte to elute and is unique in each sample. The linear velocity that is enhanced by the high pressure that is used gives the components minimal time to diffuse inside the column. This is necessary because it allows for a higher resolution of the chromatogram that is used to deduce results. In a typical HPLC, various miscible organic liquids are used and the modern units have the capacity to generate a maximum pressure of 6000psi. HPLC units are available commercially and the buyer selects a type that is most suitable for their need. Different types come with different detectors, for example, UV absorption detector, refractive index detector, conductivity detector, evaporative light scattering detector, fluorescence detector, and electrochemical detector.

Generally, there are two types of HPLC units, one being the preparative HPLC and the other an analytical HPLC. In the preparative type, compounds are usually isolated and purified whereas the analytical mainly gets detailed information about a sample that is passed through it. This means that the sample can be identified, quantified and its resolution obtained. The main uses of HPLC, however, are identification and purification of samples. HPLC is highly preferred by many professionals because it is accurate, sensitive, simple to use and can analyze nonvolatile samples that are sensitive to temperature changes. Furthermore, HPLC can easily be used in combination with mass spectrophotometry as a means of validating the data collected. Most chemists use the technique in the analysis of amino acids, hydrocarbon, proteins, pesticides, pharmaceuticals, among other products.

A combination of 0.7mg/ml phenol, 4.0mg/ml toluene and 5.0mg/ml ethylbenzene is dissolved in 10ml isopropanol. The amount of each of the above components is then calculated accordingly to allow for later calculations.

In this case, an ethical dilemma faced by the school counsellor is that he/she might end up requesting for information from the student that is no consistent with the aim of the entire counselling session (Iyer, 2010, p.5). An issue exist when school counsellors do not only have to protect the confidentiality of the student. they even have to abide by the parent’s right to gain information about their children (Brigman, 2005, p.21).

One way for avoiding this dilemma from even occurring is that the counsellor needs to provide different caretakers of a child including the parent, teachers as well as the administration that it is highly important for the counsellor to keep the information gained confidential (Bodenhorn, 2006). Another way through which school counsellors can avoid this issue from occurring is that they can maintain an informed consent policy (Glosoff, 2002). This means that they need to obtain consent from the caretakers of the child that information obtained during counselling sharing may not be shared with the caretakers. This consent should be in written form in order to avoid legal issues such as parents suing a counsellor for not appreciating the parent’s right to know.

At times school counsellors are faced with the issue of primary responsibility. this means that they face difficulties in drawing a line between whether their main clients are the administrators of the school or the students of the school. A school counsellor may be required by the highest authority of the school to follow his/her instructions and perform duties that are being delegated by the school principal and on the other hand, the counsellor may be required to attend a student who is experiencing distress (Froeschle, 2010). In such a scenario, the counsellor may be required to choose who they respond to first are. The ACA Code of Ethics provides direction to the school counsellors that their primary duty is to attain and maintain the wellbeing of their clients (Texas Counseling Association, 2014).

The machine was involved in at least six accidents where the patients received an overdose of radiation despite the safety programming. The overdose was to the extent that some patients received doses a thousand times greater than the prescribed radiation doses resulting in serious injuries and even death. The machine was intended to be operated on two modes the, photon mode, a high-powered electron beam mode and the proton mode, a low-powered electron beam mode.

When the accidents occurred, the machine was supposed to be operating under the low beam mode but the high-powered mode got activated instead of striking the patients with an overdose of the radiation. The patients reported what felt like a shock, seeing a flashing light and hearing a buzzing sound. This indicated an overdose but the engineers insisted that the machine was incapable of delivering the unintended doses given its software safety programming. A few days later the patients showed symptoms of excess radiation exposure and three of the patients died as a result of the overdose while the other three sustained serious injuries leading to the loss of some of their body parts (Goans & Wald, 2014).

While these accidents were caused by errors in programming, various entities can be blamed for being either indirectly or directly involved in the negligence that resulted in these accidents. The AECL manufacturer who made the machine is one of the obvious people who are to blame. The manufacturer is reported to have assigned only a single software developer the task of creating the complex software that the machine would rely on for its functioning. Additionally, very little testing was done for the machine and the software specifications were never written down (Goans & Wald, 2014). Moreover, the manufacturer’s claims that the machine was free of defects even after complaints were made were baseless. The manufacturers ought to have taken the matter seriously and actively searched the source of the malfunction before approving the use of the machine. Apart from the manufacturers who are the obvious entities to take the blame, other parties&nbsp.can also be identified who acted negligently in the whole matter.

I never saw my father going into the kitchen when my mother was home except for when my mother went to our relatives for a couple of days. During this time, my father washed dishes by himself. It was clear that my father’s responsibility was making money to support his family and his mother’s responsibility was taking care of her children and doing housework. My father’s other role was as the head of the house and decision-maker. When it was time to buy a house or a car, both of my parents went out to see houses or cars together. however, the final decision was always made by my father. There was no shared role between my father and mother.

I learned how to act like a girl by parents’ teaching. When I wore simple t-shirts and jeans to go out to meet my friends, my mother pointed to my outfits and chose good looking dresses for me. When I spoke loud, my parents pointed out I should speak softly. However, when my brother was talking in a low voice, my father told him “Speak like a man.” My father stressed to my brother that men should be able to play any sports, so he registered some classes for my brothers such as Tae Kwon Do, Judo, Basketball, Baseball, and Track. He did not register for any sports classes for me or my sister. My parents had two sets of expectations and rules and they applied one for my brother and the other for my sister and me. I started having doubts about the practices of maleness and femaleness when my mother started working to support the family. My father quit his work and started his own business. However, it did not go well. My mother looked for a job to help my father. She worked for eight hours a day, came home, and did all house chores the same as when she was a housewife. When I saw my mother dragging her tired body to the kitchen, something in my heart made me very uncomfortable, that was a feeling of unfairness. I did not verbalize my thoughts. instead, I helped my mother with house chores because I was the firstborn child and was a girl.
