Final writing exercise Essay There are three phases whereby each has a different crystal structure at three different temperatures. At room temperature (298K), Phase III is present whereby Cs3H(SeO4)2 has a crystal structure of a monoclinic with a space group of C2/m. At 400K, Phase II is present whereby Cs3H(SeO4)2 has a crystal structure of a monoclinic-A2/a symmetry. At 470K, Phase I is present whereby Cs3H(SeO4)2 has a crystal structure of a trigonal with a space group of R3-m. In Phase III, as we can see in Figure 2(a), the positioning of the tetrahedrons is parallel to the a-axis, and in between these SeO4 tetrahedrons are the hydrogen bonds. Looking at a 2dimensional perspective, we can also see that there is a translation movement of the SeO4 tetrahedrons along the a-axis; hence the symmetry operator would be a glide line parallel to a-axis. In a 3-dimensional perspective, we can see that Phase III has a 2-fold rotation axis and contains glide planes. In Phase II, from Figure 2(b), we can see that the positioning of the SeO4 tetrahedrons are along the approximate direction [310]. Observing the schematic of the crystal structure in Phase II, we can see that there is a vertical mirror line in between the SeO4 tetrahedrons. There is also an a-glide reflection vertically. In Phase I, from Figure 2(c), the positioning of SeO4 tetrahedron is similar to that of Phase II, however the difference is the crystal structure and the hydrogen bonding. Comparing both Phase II and Phase III crystal structures of the compound, Phase II contains two-fold screw axis, inversion center and a two-fold rotation axis, which is the sole reason for Phase II to be twice of that of Phase III in terms of geometrical  arrangement of hydrogen bonds. From the above analysis of the symmetry of the crystals structures in different phases, we can tell that Phase III has the most symmetry operators and hence achieving the highest crystal symmetry generating a low geometrical arrangement of hydrogen bonds. Due to the low geometrical arrangement of hydrogen bonds, the mobility of protons decreases giving the result of ferroelasticiy. The drastic change from superprotonic conductivity to ferroelasticty happens when there is a change from Phase II to Phase III. The major difference between theses 2 phases is the hydrogen bond arrangement. Paragraph 2 Under the optical microscope, we can observe that the polymorphic domains will alter at each phase transition to a different extent. We can see in phase III that the domains in the Cs3H(SeO4)2 crystal are made up of polydomains separated by two kinds of domain boundaries. The two kinds of domain boundaries are categorized as the planes of {311} and {11n}, where n is determined by the strain compatibility condition. The domains at the sides of each domain boundary are related to the reflective symmetry or the rotational symmetry on that boundary itself. Furthermore, we can observe that the angle between any domain and its neighboring domains is approximately 120 °, which is very close to the theoretical values calculated using the lattice parameters. As we move on from phase III to phase II, we can observe that the domain structure alters slightly by the phase transition of TII–III. Similarly, the reflective symmetry and rotational symmetry also changes at the same phase transition. However, the kinds of domain and domain boundary remain the same as those in phase III despite a change in domain pattern. This could be due to the slight change in alignment of hydrogen bonding between the SeO4 tetrahedrons when the existing hydrogen bonds were broken to form new weaker  ones. This might explains why their lattice parameters a and b do not really change appreciably. Compared to phase III previously, the angle between any domain and its neighboring domains in phase II is also approximately 120 ° and is justified by the theoretical values determined from the same equation we used for phase III. Hence, this suggest a slight change in the Cs3H(SeO4)2 crystal structure at the phase transition of TII–III. From phase II to phase I, the domain boundaries is observed to have disappear just before the curie temperature of the phase transition of TI–II and the crystal structure changes from  optically biaxial to optically uniaxial. This could be due to an external stress caused by the atomic rearrangement of the SeO4 tetrahedrons in the Cs3H(SeO4)2 crystal as a result of breaking the hydrogen bonds between them. Paragraph 3 Higher temperatures for most material will enable atoms to move to low energy sites, fitting into a perfect crystal symmetry. Cs3H(SeO4)2 however behaves differently. As the temperature increases (above 396K), its crystal symmetry decreases when it changes phase from III to II. The orientation of the hydrogen bond for phase II and III differs. For phase II, the orientation is along [310] and [3-10] direction whereas for phase III, it is parallel to the aaxis. As the transition from phase III to II occurs, the precursor of the superprotonic conductivity is observed. In order for movement of proton to occur, the breaking and then recombination of hydrogen bonds are required. For phase III, in order for the movement of one proton, the breaking of 2 hydrogen bonds is needed. The reason as to why 2 hydrogen bond is needed to be broken and recombined again is because for the movement of one proton to occur, it must break the hydrogen bond it resides in and then change its orientation, recombining at another site; the mirroring effect of opposite hydrogen bond is required to maintain the crystal symmetry i.e. to say that the another hydrogen bond parallel to the previous hydrogen bond site needs to be broken and recombined at other site parallel to the newly  recombined hydrogen bond. In this way, in phase III, the recombination of two hydrogen bonds is simultaneously needed for one proton transport. Phase II however, behaves differently. The movement of the proton is independent of the other protons at other hydrogen site. The crystal structure allows for this flexibility of the proton motion, which the superprotonic conduction takes place. The mechanism in which proton transportation occurs in the polymorphs is by the diffusion of protons through a hydrogen bond network, by the cleaving and formation of the hydrogen bonds. However, in certain phases, the cleavage and formation of the hydrogen bond might differ. The fuel cell works on the basis of the movement of protons. The movement of electrons should be disallowed as it would short circuit the fuel cell. Hence, a membrane is used to allow only the movement of protons across and not electrons and gases. On top of that, in order for a superprotonic effect to occur, the flexibility for proton motion must be allo wed. Hence, the lesser symmetrically patterned the phases the protons reside in, the higher this flexibility.

Anthropology Today Essay -- Anthropology

Anthropology Today In society today, the discipline of anthropology has made a tremendous shift from the practices it employed years ago. Anthropologists of today have a very different focus from their predecessors, who would focus on relating problems of distant peoples to the Western world. In more modern times, their goal has become much more local, in focusing on human problems and issues within the societies they live. This paper will identify the roles anthropologists today play, such as where they perform the bulk of their work, and what it is they do in both problem solving, as well as policy making. It will also identify the issues they are faced with, that is, the nature of the problems they address. Ethics have always been an important part of anthropology, and this paper will also deal with the ethical goals of today's anthropologists and some of the ethical problems they are faced with. The information of this paper was obtained entirely from the internet. It was designed as an internet project structured to both teach and familiarize research through the World Wide Web. Any data in this paper was derived through information posted publicly on internet sites available to any member of the public with an internet connection. As a result of the narrow area of research, the information provided both to the author and the reader is limited. While it is true that the internet is a source of boundless information, the sheer amount of it all makes reading all of it impossible. Also, the total lack of journal reports, or texts, means that while the information provided may not be minimal, it is nonetheless limited. When people think of an anthropologist, the image of the jungle traveling character comes to mind. A white man sitting in a hut on some primitive island, taking notes on the local tribes s/he is living with. Decades ago, this was actually the case. However, as time progresses, so does the role of the anthropologist in today's society. Very rarely now does anthropology actually involve extensive fieldwork in an exotic location. Today, an M.A. or a Ph.D. in the field of anthropology means that a job locally may be available to you. There is always the academic side of things, such as becoming a professor of the discipline, but this paper will focus more on the non-academic roles of the anthropo... ...y have come full- circle; no longer do they study the foreign, but now study the local. Their positions in society are almost too many to mention, but the severe increase in the business world must be mentioned. It can be said that the discipline of anthropology covers a wide variety of tasks as well as overlapping with other fields of the social sciences, but that statement becomes more true with each passing year.

Ambulatory Care and the Mental Health Services

Adults with serious mental illness and children who have serious emotional problems are part of the mission for the Substance Abuse and Mental Health Services Administration’s Center for Mental Health Services (CMHS). SAMHSA (substance abuse and mental health services administration’s center for mental health services, according to their principles provides a national leadership forum that â€Å"improves quality and availability of treatment for the mentally ill, especially adults with serious illness and children with emotional disturbances.† They promote managed care systems in order to carry this out. This paper will compare the principles of this system with those of the IOM. SAMHSA promotes two major principles in care and those include quality of care and consumer participation and rights.In quality of care is included the need to treat all patients with respect and dignity, basing all decisions and treatments on best practice, developing delivery and data collection systems, ensuring that services are tailored to individual needs, established verification processes for credentials, providing a way for providers to resolve disputes, ensure a continuum of care, ensure a wrap around for children, and incorporate targeted prevention activities. Further, they have a set of principles which involve consumer rights and protection.Plan members should be involved in discerning care, respect should be shown for choice of service, necessary legal and ethical rights, education for all consumers, families, and supporting consumer rights, and ensuring confidentiality. Comparison with IOM In comparing this to the supportive beliefs of the IOM, the primary goals are quality of care and improvement if not doing away with the inequities of care in this country as well as the ideal of seamless service. These are very important factors in moving care from the treatment of illness to the prevention of illness.Allowing for a continuum of care as well as a stable base of care is important as well as the need to be able to have testing done that might provide prevention for diseases such as colon cancer. Mental health and community care is also strong in the quality principles that they have applied (IOM. edu). In fact many of the principles of the two areas are well matched. It appears that some of these principles will be seen in the new healthcare also, as it includes prevention as part of the mandatory insurance rules.For example, many people were unable to have a colonoscopy because of the cost or the copay that will not longer be so as preventative has no cost or copay if you have insurance. Treating Veterans with PTSD The new IOM as well as the SAMHSAC have principles that dictate treatment based on need, respect, and dignity. The new principles in both cases address serious mental illness which would certainly include PTSD. Veterans with mental illness are presently one of the disparity groups and these groups are the ones tha t the IOM is attempting to bring to attention at this time.This can only help this group of people. Conclusion The mental health issues in this country, among other very difficult health issues have been on the back burner for some time. With the advent of the new health program and support by these two agencies, there is hope that there will be improvement in this care. SLP Articles The articles chosen were Prevention best Medicine and Health Centers to get 250 million in grants. These two articles seemed to be collaborative articles in solving the same issues.Prevention best medicine by Emily Bregel (2010), states that there has been a history of delay in preventative care in the US. This is caused because of the expense of the tests, not covered by insurance or those that have costly co-pay. Under the new healthcare reform law, health insurance plans that begin on or after Sept. 23 must cover recommended preventive services and cannot charge patients co-payments or deductibles. T his causes a shift in the type of care that is given from coverage for illness to coverage for prevention of illness.Many of the larger insurance companies were interviewed and it was felt by most that this would not be a large difference in cost for them as it will decrease costs in the end. This whole change will be better quality care for the patient. Health Center to get $250 million in grants by Fears (2010) reviews the newer grants that are available for building community clinics in an effort to boost service. Of course, health centers across the country are lining up to get a piece of this money.Many of which got quite a large grant last time it was offered and because of growth need granted money again. The funding is available under the Patient Protection and Affordable Care Act and is meant to establish medical homes for patients that at this time do not have them. These health centers have been the safety net for the uninsured to provide comprehensive medical care as wel l as pharmacy, mental health, substance abuse treatment, and dental care. This is a part of the continuum of care as well as a place to use the new prevention funds to stave off chronic illness.References Bregel, E. (2010). Prevention best medicine. Health. Fears D.

Maid: the Great Gatsby Essay

â€Å"Things gained through unjust fraud are never secure.† -Sophocles. Up to chapter 5 of The Great Gatsby by F. Scott Fitzgerald, there are recurring rumors about Gatsby’s background including that he had killed a man, is of German descent, and is a bootlegger. These rumors portray Gatsby as a man other than himself, but whether this is true is still uncertain. However, Nick’s keen awareness of Gatsby’s servants raises suspicion and allows readers to attain evidence that reveals Gatsby’s true identity. The maid, seen by Nick and portrayed through her actions, undermines Gatsby’s status and reveals his identity as phony. In chapter V, narrator Nick observes Gatsby’s house, but it is clear from Nick’s observations that something is not right; everything seems artificial and inconclusive. Nick notes that a brewer had built Gatsby’s mansion, and Gatsby tried to â€Å"pay five years’ taxes on all the neighboring cottages if the owners would have their roofs thatched† (88) so that it would complement Gatsby’s house. It is important to emphasize that Gatsby had specifically paid for the neighbor’s taxes in order to improve the looks of his house. This ostentatious action was done for reason: to attract Daisy. Nick also concludes that Americans have always been obstinate about being peasantry. At this point, he observes: â€Å"A maid began opening the upper windows of his house, appeared momentarily in each, and, leaning from a large central bay, spat meditatively into the garden.† (88) Nick sees the maid â€Å"spit into the garden† as if she di srespects Gatsby. It is important to note that the maid spat â€Å"meditatively† meaning that it was done with intention and with great thought. There was no reason for her to spit, nor was spitting a common action back in the 1920’s, but her intentions were hidden. While she â€Å"spat† in Gatsby’s garden, one of his valuable properties, her action was actually directed towards Gatsby himself. From this, it can be inferred that she disrespected him and despised him for his wealth, upper class, and fame. While Gatsby exploited his wealth, intending to impress Daisy, the maid, completely oblivious about Gatsby’s goal, could also have despised him for his pretentious attitude. Maids were usually part of the lower class, and it raises suspicion about why Gatsby would hire such a person. More importantly, it raises the question as to how she knows a lot about Gatsby and why she would hate Gatsby for his wealth. Her decision serves as a juxtaposition; Gatsby and the maid share similar qualities. Perhaps Gatsby’s background does not match the image that he portrays. It raises suspicion that Gatsby might be from the lower class as well and lives his current life as a fraud. Fitzgerald puts the maid here in this chapter to insinuate something about Gatsby’s background. Nick’s keen observations and suspicious judgment gives the readers an opportunity to make connections. Ultimately, it is the connection that Gatsby and the maid were both raised in the lower class. Perhaps Gatsby was a bootlegger, and his ways of promoting himself into the upper class led to the maid’s actions;, it was her reaction in contempt that spoils the true identity of the great Gatsby.

Alpha and Omega of Active Compasion essays

Alpha and Omega of Active Compasion essays Alpha and Omega of Active Compassion Have you ever walked down a crowded city street and looked down to see a homeless man stretching out his soiled hand in hopes of a measly dollar? As human beings, are we obligated to give this man our earning? And just how much do we give him? A dollar? Our VISA card? We have a general responsibility, as residents of civilization, to our fellow man, as long as it doesnt interfere with our own personal progress. The ideals of welfare, charity, and the generous foreign policies are all prime examples of our aid to others, but the world is still uncertain on, how much do we give?. The idea of welfare was founded in the United States around the time of the great depression. It was meant to temporarily help the financially less fortunate. This was intended to get the ball rolling for the economy. The government would play Robin Hood by taking from those who had money, and giving it to help those who didnt. In time, they would put their feet back on the ground and would no longer need the relief of their government. This was a very kind and productive way to help our fellow man in his time of need. Unfortunately somewhere along the line the idea of helping the broke modified, and we were simply giving them money when they had no intention on recovering from the debts of poverty. And so we continued to show everyone else how to get money for free. This is an excellent example on how we exceeded our obligation to others. Instead of a few dollars of generosity to uphold others, we give up to half of our earnings to support those who choose not to help the mselves. By doing this, we have slowed our individual progress in society. Charity is another form of helping the less fortunate persons on earth. That, unlike welfare, is to be executed at our own discretion. There is no forcing hand in charity, although sometimes we still do not know ...

Hiral Patel Essays (795 words) - Discrimination, Demography

Hiral Patel Essays (795 words) - Discrimination, Demography Hiral Patel December 1, 2014 SOC 224 ONLN Self-Assessment Analysis Sociology is the study of human relationships in the society. The basic sociology course helps introduce to the social world of societies. It helps students to think and to believe that everything is influenced by the societies that they live in. The way people are treated at work and in societies determines their position and place in society. Sociology 101 was an exciting and knowledgeable course that encouraged thinking beyond what is given to you. Never did I realize that everyday decisions and activities contributed to relationships and the world itself. I find that sociology is the only field of study that analyzes and explains the matters in our lives and our communities. It helps explain the social causes of racial and gender identity. It helps to examine diversity in colleges and how important migrations can be for immigrants in search of better lives. Being a student, diversity in colleges was the subject that caught my attention the most. Diversity is important in colleges because it helps students learn to help and appreciate other students of diverse races. Diversity helps promote equality in schools and is also a bonus for the social status of the United States because promoting diversity will show other countries and people how the country treats everyone with equality. This attracts other people from all over the world to come and take a chance in the United States. In the United States, we see people of all backgrounds creating a life of their own. Many come in search of the American Dream while others come escaping from their old lives. United States gives each and everyone the opportunity to prove themselves and work to live better. It does not matter what color of skin people have. Although there may be some areas in the United States that still believe in race and color, there are still areas where diversity is promo ted. I did not realize how important diversity was in colleges until this class. I cannot forget the controversy issues that were discussed in this class. It is not just the subject of the papers but also the discussion of the issues itself. After all the students uploaded their controversy assignments we all had to post comments about what we thought of the issues. That was when we faced the real issues as sociologists. Analyzing such issues made many of us realize the controversies going around the country at this time. Because of the controversy issue, I was able to realize that although equality is promoted in the United States, there should also be a limitation. The country cannot have all gay people marry each other and adopt children because we will be setting a bad example for people in other countries. There is no doubt that everyone should be treated equal but having children grow up in gay families is also unacceptable because then no one will believe in marrying the opposite sex. Another controversy issue that we discussed as a class was immigratio n. Although immigration laws should be kept strict, I found that there should be exceptions to immigrants who have families in the United States that are unwell. If someone is in the hospital or on the verge of dying, then the immigration laws should give exceptions for at least a week to visit the person. The last controversial issue that was discussed was that diversity should matter in colleges. There is no point of having different colleges if there are the same people all over the campus. What would be the point of having dorms then when people can study from their bedroom with the same people. Students attend colleges so as to build their strengths and to strengthen their weaknesses. These controversial issues will definitely be useful to me in my future career and educational goals. Gay rights, immigration laws, and diversity all play major roles in sociology, which is why they were controversial issues being discussed in my class. They will definitely be useful to me in the future because these are issues that come up at any point in my life. These topics are the most discussed topics in our societies today. Immigration
