Culture, Society, and Globalisation

Introduction International and rural-urban migrations are actively discussed by scientists because some aspects of these processes are still not thoroughly researched. It needs to be said that there are both benefits and adverse factors that are associated with immigration.Advertising We will write a custom essay sample on Culture, Society, and Globalisation specifically for you for only $16.05 $11/page Learn More It is paramount to note that international and rural-urban migrants have a mostly negative impact on the way culture and economies are shaped in global cities because their presence often leads to conflicts with native citizens and other substantial issues. The key aim of this essay is to draw attention to this fundamental problem, and it will consist of paragraphs that prove this point of view, and a conclusion. Current Issues Economy The central problem that has to be focused on is that native citizens in global cities often struggle with emp loyment. It is paramount to note that one of the primary factors that lead to such situations is that foreign workers are ready to accept wages that are much lower, and they can work in environments that are not safe, and this situation is taken advantage of by employers most of the time. Dubai can be viewed as one of the best examples of complications that occur because of international migration. For instance, the dissimilarity between the numbers of immigrants and native citizens in this city is so enormous that foreign workers are viewed as significant threat (Hamza, 2015). Furthermore, the government has reviewed its perception of immigrants and understand that that some severe risks are related to their interaction with native citizens. In addition, it is imperative to say that the economy of the city is extremely dependent on cheap labor. One of the primary issues that should be noted is that the situation may become incredibly unstable if there is a crisis that affects low-s kill workers. Moreover, inflation may also play a significant role because the housing market is influenced most of the time, and it is a threat to low-income employees. New York should be viewed as one of the best examples of a city where people of different nationalities co-exist. However, the government places a severe limitation on the number of migrants that are allowed to enter the country, but illegal migration is still a significant problem that should not be disregarded and addressed. Also, remittance is a major issue because most migrants do not want to spend their money in the city that they live in and prefer to send it to their families and relatives in other countries.Advertising Looking for essay on social sciences?

This particular problem is note-worthy b ecause it limits the development of cities. However, it is understandable that migrants want to support their families, but more opportunities should be available because it is a significant barrier that hinders the possibilities for development of cities. Moreover, the major problem is that foreign workers are currently not allowed to invest in businesses in Dubai, and they are faced with other substantial limitations. More specifically, some of the policies that are established are aimed strictly at foreign employees. However, it cannot be viewed as an efficient way to deal with this problem because it creates enormous tension. Consequently, migrants understand that they are treated unfairly and often stage protests that are not allowed in some regions such as the United Arab Emirates. Furthermore, it is perceived as a significant issue by natives because it is hard for them to accept that some individuals do not respect their laws and traditions. It is imperative to say that incr ease in the number of both international and rural-urban migrants is viewed as problematic most of the time because the overall productivity of the workforce is often reduced. Overall, individuals that have moved from rural areas and less developed countries often struggle to find jobs because they do not have the necessary knowledge to use current software programs and technologies, but some professions are introduced to deal with the problem of unemployment (Zenou, 2011). Culture It also needs to be said that culture also suffers most of the time. Cultural diversity is necessary, especially when it comes to global cities. However, it becomes a problem when the overall identity of the region is in danger. The difference between religions is also one of the problems that need to be discussed. It is especially problematic in cities like Dubai, where Islam is much more dominating than the other ones. It is hard for them to accept some of the customs and traditions of other nationaliti es, but significant progress should be noted. For example, native citizens often voice their negative opinions about immigrants in Moscow. The population of Tajik migrants is enormous, and it leads to several problems (Bakhromov Levy, 2013).Advertising We will write a custom essay sample on Culture, Society, and Globalisation specifically for you for only $16.05 $11/page Learn More It needs to be said that the people of Moscow is not as tolerant as in other cities, and numerous conflicts often occur. It is of vital importance to understand that language barrier is one of the central issues that need to be addressed. Additionally, it has to be said that tremendous influence of migrants already can be seen in most global cities, and some products and advertisements are aimed strictly at expatriates. Another social issue that needs to be discussed is that most have an incorrect perception of other nationalities. However, it needs to be said that racism an d discrimination are not as prominent as they once were, but they can still be perceived as significant threats to the development. Native citizens in some other major global cities such as Toronto are still not used to ethnic diversity, but the situation is getting better every single year. Another aspect that needs to be considered is that individuals often migrate to regions that do not have developed diasporas because they view it as a significant benefit (Somerville, 2015). In addition, the dissimilarity between the numbers of male and female migrants is dramatic. Evidently, the prime reason for such difference is that types of jobs that are offered to foreign workers often require only physical strength. However, it is necessary to say that some individuals move to global cities with their families to look for better opportunities. It is essential to emphasize the fact that most of the migrants are low-skilled and lack education is a significant issue because it severely limit s the opportunities for development of the cities (Hu, 2014). In particular, Sydney has an enormous potential to provide unique global services that are related to knowledge, but significant percentage of migrants lack education, and this fact needs to be considered. Employers recognize the advantages that are associated with migration of the workforce and take full advantage of this fact from the economic perspective. Safety Safety of the region is in danger when there is a significant population of migrants. Firstly, one of the problems that need to be discussed is frequent confrontations between the groups that are formed. They are often armed, and numerous casualties can be frequently noticed.Advertising Looking for essay on social sciences? Let's see if we can help you! Get your first paper with 15% OFF Learn More The issue of terrorism is also quite significant, and should be taken into account because it becomes incredibly easy to organize attacks and other activities with the resources that are available in global cities (Sassen, 2002). This fact has a negative impact on both economy and culture of a particular region. It is evident that people are likely to view a group of individuals of a certain nationality as terrorists, and it leads to a vast number of conflicts and confrontations that could have been avoided. Secondly, it is evident that high percentage of foreign workers may be viewed as a significant issue in case there is a military conflict because it will be nearly impossible to organize and evacuate the citizens. More specifically, it is especially problematic in cities like Dubai that are extremely vulnerable to terrorist attacks, and it needs to be said that the country as a whole is in danger, and the government is looking for the solution that would help to resolve the issu e that has occurred. The most significant threat that needs to be discussed is that migrants often have to endure appalling conditions, and it results in severe health problems. Some of them are not vaccinated, not to mention that it can lead to a catastrophe in case epidemic breaks out. Therefore, diseases are spread among migrants at incredibly fast rates because some significant issues with health care are still present. Similarly, sexually transmitted diseases are also extremely problematic because a vast number of migrants do not have the necessary knowledge about the measures that should be taken to guarantee the safety of sexual partners (Bakhromov Levy, 2013). People of the same nationality often create communities that provide help to individuals that need it. Moreover, such organizations are often viewed as threat because they may participate in criminal activities. However, it needs to be said that a recent study has shown that that immigration does not directly influenc es crime rates (Zatz Smith, 2012). Nevertheless, drug trade may develop because of illegal immigration, and pathways for drug trafficking can also be introduced. Easy access to stimulants is quite problematic because numerous complications are associated with substance abuse. The crucial aspect that should be considered is that it may cause significant damage to the economy because international companies are less likely to invest their capital in such regions. Overall, the biggest issue that has to be addressed is that health and well-being of citizens may be in danger, and it is a humongous point of concern. Conclusion In conclusion, it is hard to argue with the fact that international and rural-urban migrations are essential for modern society. However, it needs to be said that numerous complications that are related to these processes are currently present, and it will not be an easy task to address all of them. All things considered, the primary reason for the issues that occu r is that there are tremendous differences between numerous cultures and traditions. Moreover, such drastic problems as racism and discrimination still exist, and it will not be an easy task to address all of them. Nevertheless, tremendous progress in this particular area has been shown over the last few years, and it is extremely likely that new technologies that are being introduced will be able to resolve some of the problems.

Best Places to Study on a College Campus

Best Places to Study on a College Campus Finding a place to study on a college campus can be a challenge. Even if youre lucky enough to use your room for periods of time without having your roommate barge in, you still might need a change of scenery from time to time. Any of these places to study on campus can do the trick! Libraries Look for nooks and crannies in the undergraduate library. See if you can rent a carrel or small study room. Head to a floor youve never been to before. Check out the stacks and find a small table pushed against a wall somewhere. There are undoubtedly little spaces you can find that will help you focus on the task(s) at hand. Head to the medical, business, or law library for a completely different scene. Nice furniture, quiet study rooms, and nicer digs are much more common here, and youll be less likely to bump into- and get distracted by- people you know. Check out the smaller libraries on campus. Many large schools have tiny libraries scattered around. Ask for a directory of libraries and find one that is small, not busy, and perfect for getting some work done. Coffee Shops If you work best with some background noise and a distraction now and then, not to mention easy access to food and drinks, the campus coffee shop may be a good bet. Outdoor Areas When the weather is nice, reading out on a lawn can be a great way to get some fresh air, clear your mind, and still get some work done. If youre worried about running into people you know, head to a part of campus you and your friends dont usually visit. Classrooms Check out empty classrooms. You dont have to be in class to take advantage of a nice classroom: if a room is unoccupied, feel free to claim it as your own and get to work. Utilize the campus computer labs. You dont have to be using a computer to take advantage of the quiet atmosphere that most labs provide. Grab your work, your laptop, and an empty seat at a table and enjoy the lack of noise and distraction. Other Areas Camp out in the dining hall during off hours. When everyone is free for lunch, the dining halls are totally chaotic. But between meals, they can be quiet and peaceful. Grab a snack and enjoy the large table space you wouldnt otherwise have access to. Head to larger venues that arent in use. Large theaters or music halls often arent in use all the time. Head to one of these areas for some quiet time in a place that can help free your mind from distraction. Reading Shakespeare in an empty theater may be just what you need to get into your assignment! Use a Tutoring or Learning Center Peek into a writing/resource/tutoring/learning center. Many campuses offer resources for students working on projects. Even if youre not meeting with any of the centers volunteers or staff members, see if you can work there for a few hours.

Hispanic in united states Research Paper Example | Topics and Well Written Essays - 2250 words

Hispanic in united states - Research Paper Example C. Nelson and Marta Tienda noted, â€Å"Hispanic as a label combines colonized natives and their offspring, foreigners and political refugees under one ethnic umbrella, but coherence of this label is questionable on theoretical and historical grounds† ( Oboler, 1995). It is evident that some researchers have pointed out the political cost of the debate while other researchers have identified its demographic connotations of census definitions since 1930s. The label â€Å"Hispanic† arrives from time of arrival, language, race and minority status (Oboler, 1995). Understanding the ambiguity of the term, Joan Moore and Harry Pachon raised referred to the concept as â€Å"racial minority or simply another predominantly Catholic ethnic group like the Italians for example† (Oboler, 1995). According to Pastora San Juan Cafferty and William McCready, â€Å"policies are created for Hispanics which help some and ham others because there are in one sense no generic Hispanics† ( Oboler, 1995). Revolution in the global economy and its bang in US labor market have opened a new paradigm for immigrants from Latin America. They deal with a fall of industries like clothes making, providing untrained, admission level jobs to recently arrived populations in United States (Oboler, 1995). According to the results of Census 2000 there is a remarkable increase in the Hispanic population form 1990 and has increased from 22 million to 35.2 million. The total Hispanic population is categorized into two groups: A. native Hispanics- those born in US who possess Hispanic heritage and B. foreign born Hispanics they either have or do not possess US citizenship. It is estimated that both these categories contributed to the increase in Hispanic population, but the foreign born Hispanic population experienced surprising growth in their population owing to the enhanced immigration (Grieco,

Reflection on Therapeutic Interaction Essay Example | Topics and Well Written Essays - 1250 words

Reflection on Therapeutic Interaction - Essay Example On this perspective, it is thus imperative for nurses to deliver the right practices to enable achievement of appropriate results. These positive outcomes benefit both the nurse and the patient (Kaptchuk 2008). Nursing therapeutic practice is a highly engaging exercise that demands exclusive attention from the nurse (Donaldson 2010). Nursing is also an emotional exercise that involves exchange of emotions and feeling to be able to draw sympathy and empathy since it is a comforting exercise. After the exercise, it is imperative that nurses develop a sense of reflection to enable theme develop improvements in consequent practices. In this regard, while reflecting on a recent therapeutic care I had on a sixty five year old patient, Marylyn Morrison, who had just undergone replacement surgery of the hipbone, I developed a reflective exercise made an evaluation of the steps involved in the care practice and their implications in nursing as a practice. The reflection would then enable futu re achievement of better outcomes (Smith 2011). Unconditional acceptance As a professional nurse, one is bound to give complete acceptance, not based on any condition such as race, sex or ideology, granted to the patient. In this reflection, it came to my realization that when such acceptance is given to the patient, the same is reciprocated from the patient and thus confidence develops in the patient (Lombard 2011). Such confidence leads to development of mutual trust and thus fosters a faster healing process. In this reflection, Marylyn was hesitant to open up at first but upon realization that the therapeutic care was unconditional, she developed faith and within the duration patient-oriented care was administered to this patient, effective psychological and physical healing processes were achieved at a fast pace; beyond expectations (Thompson 2010.). The learning experience attained from the therapeutic care delivered brought a wider scope of understanding of acceptance that nee ds to be given to a patient despite some conditions that might be considered slightly out of the ordinary. In her special case, the patient had very complicated social sense of acceptance and was resistant to nursing acceptance. However, relentless unconditional acceptance changed the situation at some point during the delivery exercise. Mitchell and Cormack (2008) argue that acceptance is not easily achieved even if given free of charge. Individual differences account for different reactions to situations. Introverts feel better off staying alone under normal conditions. Due to their solitude nature, they find it hard to accept new social circles in their lives. ON the same note, they also find it hard to open up during therapeutic delivery exercise (Maciocia 2010). While the patient continually showed signs of rejection towards the therapist during the early stages of care, persistent and convincing acceptance given to the patient helped change the situation. After three weeks of the nursing care exercise, the patient learned how to give appropriate response to the unconditional acceptance give during the care. She learned to voluntarily accept in return and thus eased the process of the care exercise. This was a great lesson since acceptance cannot be compelled on an individual. Therefore, unconditional acceptance may take time to be effective but with patience in situations such as the case above,

Creating a conducive classroom Enviroment

Creating a conducive classroom Enviroment When I think of a conducive classroom, the first thing that comes to mind is the climate and atmosphere of the room. Is the room inviting? Is the environment set up in such a way that everyone has access to everything in the room? Does the teacher come off as a warm, caring person? In a conducive classroom, it is the teachers role to create such an environment that children can and will succeed regardless of their educational background, their cultural background or even the language they speak. A teacher needs to establish an effective climate where she still maintains authority and organization, where there is mutual respect and good rapport between each other. As an educator of ELL students, the classroom needs to be a place that will influence the childs achievement and help boost their self-esteem, and have planned organized activities at their levels which can produce success. The ELL student can present many problems for a teacher in the classroom if the teacher is not prepare d to teach this type of population. ELL students often come to school with many disadvantages such as learning a new language, learning new content, cultural differences, socioeconomical issues and the list could go on. In his book, The Natural Approach: Language Acquisition in the Classroom, Stephen Krashen often speaks of the different levels for Language- Acquisition-sometimes referred to as The Natural Approach and how it is a natural process for students to learn the language. In fact, some say it is so natural that it requires very little education and planning on the teachers part, for an ELL student to learn a new language. I took this to mean, if you just put them amongst their peers the learning and language-acquisition will happen. But, as an educator for many years, I can honestly say, I have worked very hard to establish the best policies and practices for a successful conducive classroom. But even after many years of working with the ELL population, I can honestly say I can improve on different strategies that would not only make me a better teacher, but would also benefit my ELL students as well. Problems or issues in the classroom: Building Trust If I had to make any improvements working towards a conducive classroom for my ELL students, I would have to say I could work on establishing more trust from my students, and working on my routines in the classroom. Even though I try to establish a sense of trust with every student, sometimes you will not gain every ones trust in the room but a teacher must continue to try. That is why before the school year even begins, I try to get to know my students during the Meet the Teacher Day offered at our school the week prior to the first day of school. It is during this time I start to build trust. This gives us a chance to get to know one another and during this time, I start to get a feel for my students, their parents, and the family situation. From the minute I shake their hand at meet and greet, I try to make them feel as if we have been together an entire school year already. To help gain trust, I begin by letting them explore their classroom, choose what seat they would like, and I ask them a few questions about their likes and dislikes. I want my students to feel as though I care about them as a teacher and a friend. Even though I try to establish a student/teacher trust, a problem I have found over the years is that not all students feel they can trust a teacher or other adults because of their cultural upbringings. Even though I tell them they can come to me for anything, many are hesitate because they do not want to get a family member in trouble, and believe me, I can see how this affects their school work. So, my solution to the problem is to share personal stories that I think the students can relate to and then ask if anyone has had something similar happen to them. Sometimes it works and they trust in me, other times, they simply keep things inside. Another way I try to establish trust is by showing the student that I care and value their language and culture. I start doing this by pairing up a limited English speaking student with an English proficient student that will help them throughout the day or however long they need each other. Research has shown that when students can continue to learn in their own language the non proficient student will actually learn English faster (Cummins, 1991). That is why, as I am teaching my lessons, I will allow my students to speak to each other in their native tongue which helps the non proficient student understand what is being taught and what is expected of them. There is nothing worse than having new students get lost at the beginning of a school year, and then you will have lost them forever. Even though I try to establish trust in this manner, there are still times I may forget about the non proficient student and when I hear talking during a lesson, I sometimes get upset only to real ize they are translating for me. I feel that every teacher needs to get to know their students on a personal basis; they need to build trust and respect for each other. Teachers need to look beyond the students proficiency levels, their cultural backgrounds, their social-economical status, and remember they are people and we need to embrace our differences and teach them as we would any child. By building a relationship of mutual trust, a teacher can help relieve the anxiety many ELL students feel and therefore provide a conducive classroom that is beneficial to all. Research on Building Trust Maslow, (Maslow, 1968) discusses the basic strategies for safety and security for a new student. One of the very first things he says is that every new student should be assigned a personal buddy, preferably one who speaks the same language. This person would help the new student throughout the day to make sure he/she knows the routines and how to navigate around the school. Additional solutions include that of established routines. Research states if a classroom has routines in place, this can help to lower the ELL students anxiety and it helps them become a part of the classroom (Krashen Terrell 1983). Problems or issues in the classroom: Daily Routines Another issue I may face is trying to set-up the perfect routine. To me, there is nothing more conducive in a classroom that has structure that will promote student success. Structure and routines in a classroom can make all the difference in a successful or a non successful room. In the beginning of the year, I have simple routines that everyone, regardless if they speak English or not, can follow. The routines are so basic and they establish what is expected of each and every student. By having such a routine in place, any new student, ELL or otherwise, can come into the room and know what is expected of them after just 1 or 2 days. A well planned routine helps ease the expectations of many new comers. It does not require them to know English to begin fitting into the classroom. My routines also include how groups are made and organized. I have small groups for every subject area and the students know where they are assigned. Even though I like to think I have the perfect routine established, and my students know how to move from one routine to another, that is not always the case, because at a Title 1 school, I have found that routines are made to be broken, which is something I have to learn to deal with. At a Title 1 school on any given day, I receive numerous intercom interruptions from the office or other teachers asking for so and so to be sent to the Counselors office, or nurses office, or reading/writing lab, or my favorite, they are going home, could you make sure they have their homework. Call me old-school, but, I really like a structured classroom, so whenever I am interrupted it throws everything off. I found that I have to monitor and adjust my schedule on a daily basis, so you can imagine how my students feel when I say, OK we need to change this or that, it takes them a lot longer to adjust. So, I guess one problem I have when establishing a conducive classroom is how to deal with change on a daily basis and how to make the transitions easier for my students as not to disrupt the learning going on. Professional Research on Routines Establishing routines in the classroom is one of the easiest strategies to help ELL students lessen their stress and enjoy their days in schools. In their book, 50 Strategies for Teaching English Language Learners, (Herrell Jordan 2008), go so far as to walking a teacher through the process step by step on how to set up a classroom. Other research also mentions that ELL students need cooperative groupings to interact orally with their peers (ESL learners: a guide for classroom teachers). The guide goes on to say that structured learning groups have many positive outcomes in academic achievement, increase in communication skills, race relations, and social development. I am a firm believer in cooperative learning groups. There have been many times I have seen students teach other and explain things to each other, in only ways they understand. Where I am in producing a conducive learning environment As a veteran teacher of 15 plus years, I believe I already have a classroom that is conducive to the ELL student. To me, it takes many years to establish such a room where the ELL student can produce and become successful. I have implemented many strategies to help ensure the success of each and every one of my students. My classroom is arranged in such a way that students have access to everything they need from bilingual dictionaries, technology, manipulatives, realia, learning centers, and small groupings. I also differentiate instruction, have established routines and structure, I embrace and learn all about my students cultures, I create an environment that makes a child feel comfortable and one that helps to relieve all anxieties a child may feel when entering a strange new place. I instill a love of learning through motivation, hands-on activities, and positive feedback. I understand as an educator that every student has different needs, and the ELL population may have even mo re than your typical American student, but I do whatever I have to, to make sure they have everything they need and to make sure they are in a conducive environment that is task-oriented, engaging, and supportive so that they can and will be successful.
