Materials Used in the Marine Environment

Materials Used in the Marine Environment G.R.P Piping Used For Cargo Transfer Glass Reinforced Plastic Glass Reinforced Plastic (GRP) is widely used in the marine environment because of its many useful properties. Glass Reinforced Plastic is composed of fine glass fibres woven to form a flexible fabric. The weave pattern determines the strength and weight of the GRP. There are different weave patterns used for the production of GRP depending on the application. Different resins may be added to the woven fiberglass to give it added strength and allow it to be molded into numerous shapes. Weave patterns for GRP Advantages and Properties of Glass Reinforced Plastic piping GRP pipes have a major advantage of corrosion resistance (a typical property of plastics), their strength and durability. This makes them ideal for conveying all kinds of water, chemicals and other cargoes. The major advantages of GRP are: Corrosion resistance, of both the wall in contact with the fluid carried by the pipe and the external wall. Therefore the need for extra protection such as coating or painting is minimal. Chemical resistance. GRP is minimally reactive, making it ideal for chemical pipelines and other areas where chemicals are used. Easy installation procedure Low weight The smooth internal walls avoids the formation of deposits. Requires minimal maintenance after installation GRP can be made fire resistant by the addition of special additives. Glass reinforced plastics do not conduct electricity, they also resist electric sparks. Long life. Raw Materials Used in the production of GRP Polyester resins and glass reinforcements are the main raw materials used in the manufacture of Glass Reinforced Plastics. Resins Polyester resins are the major resins employed in the manufacture of GRP, although other resins such as phynol, epoxy and vinylester are used when certain performance characteristics are required. Polyesters offer a good balance of electrical, mechanical and chemical resistance properties, at reasonably low cost. They are easy to handle and also have good dimensional stability. Polyesters are usually manufactured by reacting glycols and dibasic organic acids, both of which contain a double-bonded pair of carbon atoms. The polyester resin is a thermoset, when subjected to the right conditions it is capable of being cured from solid or liquid state. There are two main types of polyester resins used. Orthophthalic polyester resin is the standard resin widely used. Isophthalic polyester resin is the preferred material in the marine industry where superior water resistance or required or high corrosive products have to be conveyed. Glass reinforcements Glass fibre is the most widely used reinforcing material. Various components are mixed to produce a basic compound which is then melted at high temperature in a furnace to produce glass. The molten glass is drawn into thin filaments which are then processed into strands that are the basic reinforcements for the resins. Glass fibres are made from silica (SiO2) sand which melts at 1993K or 1720 °C. SiO2 is heated up to 1720 °C and then rapidly cooled to produce glass. Although glass fibre can be made from SiO2 alone, other materials can be added to improve or add certain properties. There are major grades of glass necessary to produce pipes used in the marine environment; â€Å"C† glass grade: this grade has improved resistance to chemical attack and mostly used for making the inner liner of pipes. â€Å"E† glass grade: strong and low in alkali content, good tensile and compressive strength, good electrical properties but resistance to impact is relatively poor. This grade is not totally inert in chemically corrosive environments so a protective liner is required to protect the integrity of the glass. â€Å"E-CR† glass: this grade has long term resistance to chemicals. Although the composition doesn’t much from the E-glass, the resistance to acid corrosion is a lot better. This grade has Lloyd’s approval and are certified to meet the Boeing BMS-8-79 Specification. Some additional raw materials may include catalysts for polyester resins, accelerators, inhibitors, thixotropic agents, silica. Manufacturing Process Regulations associated with the use of GRP on ships The International maritime Organization has specific guidelines for the use of plastics for pipes on ships. The guidelines provide acceptance standards, design requirements, and fire testing performance standards for plastics in piping systems independent of service or location. The guidelines refer to both thermosetting and thermoplastic plastics, with or without reinforcement. Material Design Properties and Design Criteria for GRP Piping used for cargo transfer The piping should have adequate strength to accommodate severe conditions of temperature, pressure, and the dynamic conditions of the environment. Pipes should also have a minimum wall thickness to ensure sufficient strength for handling, cargo transfer and other activities on board ships. Internal pressure: The internal pressure of piping systems should not be less than the maximum working pressure expected under working conditions or the highest set pressure of fitted safety or pressure relieve valves. The nominal internal pressure for a pipe should be calculated by dividing the short-term hydrostatic test failure by a factor of safety of 4.[i] External pressure: In the design of these piping systems, the external pressure should not be less than the sum of maximum potential head of liquid outside the pipe. The nominal external pressure should be calculated by the collapse test pressure by a factor of safety of 3.[ii] Axial Strength: the sum of all longitudinal stresses due to weight, pressure or dynamic loads should not be more than the allowable stress in the longitudinal direction. In this case where Glass Reinforced Plastic pipes are used, the sum of the longitudinal stresses should not surpass half of the nominal circumferential stress derived from the nominal internal pressure determined by dividing the short-term hydrostatic test failure by a factor of safety of 4.[iii] Temperature: the piping system should be able to serve perfectly over the range of temperatures it will experience. The maximum working temperature should be at least 20 °C less than the minimum heat distortion temperature of the resin. The minimum heat distortion temperature shouldn’t be lower than 80 °C. Where pipes are to be used for low-temperature services, special attention should be given to the material properties.[iv] Impact Resistance: the minimum resistance to impact of the piping should be to the satisfaction of the administration. Ageing: When selecting design materials for pipes, the manufacturer should ensure that the environmental effects will not degrade the physical, mechanical or chemical properties of the pipes below the values to meet these guidelines. Satisfactory ageing tests should be performed on materials before selection. Erosion Resistance: The effect of erosion should be considered when designing pipes. Adequate measures (such as increased wall thickness, use of special liners etc.) should be taken to ensure the erosion resistance of the pipes. Compatibility: the materials used in producing the pipes should be compatible with the fluids the pipes are used to convey or immersed in.[v] â€Å"The manufacturer should have a quality system that meets ISO 9001, â€Å"Quality Systems – Model for quality assurance in design/development, production, installation and servicing†, or equivalent.†[vi] The quality system during manufacture should bases on requirements and standards necessary to produce pipes with the most suitable physical and mechanicals properties. GRP Pipes and Metal Pipes Comparison Because of the materials used in the manufacture of glass reinforced plastics, they have good strength and light weight. GRP pipes have smooth, non-absorbent internal walls to allow for smooth flow of the cargoes they convey. They are also inert in nature and very durable. Some other advantages of GRP pipes include high tensile strength, corrosion resistance, low density, scaling resistance, flexibility and easy installation, long life and minimal maintenance. Metal pipes are more expensive to manufacture, they react to changes in temperature and corrode quite easily. Metals are also heavier and have a more tedious installation process. Galvanized steel pipes have a high possibility of lead contamination. Over time, the physical and mechanical properties of metals degrade. GRP piping is most suitable for cargo transfer as it has the most advantages.

Flood hazards: impacts and responses for the built environment Essay

Flood Introduction What are some of the major challenges emergency managers will confront during the response phase of this disaster?   Why are these problems?   Why are these issues important to resolve?Finally, how can these problems be overcome by the emergency manager and other related actors or agencies?                   Floods are natural occurrences which are experienced during periods of high-intensity rainfall regularly. The changes in climatic patterns changes the intensity of rain and this could lead to future occurrences of floods. The emergency managers faces a lot of problems in trying to deal with this problem during the response phase. Some of the problems include communication system, geographical position, experience in handling the problem, lack of resources to deal with the emerging problem which in this case is floods among many more(Moore & Barnes, 2004).                   Communication being a very important aspect in any activity of a particular group, its importance should not be underestimated. Lack of proper communication systems during the response stage in floods would lead to poor service delivery to the affected people. The geographical position of an area would determine how fast or slow the response team arrives at the scene to help. People staying in areas that can be easily accessed by the team are always rescued easily by the team. Selecting the best team for any emergency case is always a major problem faced. Improper selection leads to poor service hence the need to always choose the best team.                   The aforementioned problems can be overcome by incorporating qualified personnel into the response team. In areas with accessibility problems, the best means available should always be sought. Good communication systems is also very important because the response team works together and it’s only through proper communication that they will render the best services. Who will be the most critical actors to arrive initially at the scene of the incident? Why are these actors so crucial? What kind of equipment and training should they possess?                   The most important people to first arrive at the flood scene should be the Red Cross members, the fire fighters, health and mental volunteers. These people form the rescue teams. They help in evacuating the people from the flood invested area.                   There exists two types of floods; those that occur gradually and the flash floods which may occur with little or no warning. The rescuers therefore undergo training to help curb all the two types. The most important skill one needs to know is the first aid skill and secondly how to operate a radio. Some however may also have the Swiftwater Training certificate. The people should be trained on hydrology which involves learning how water behaves when it’s moving quickly through a confined area. This helps them know to read the surface hence knowing the location of hidden materials like vehicle, concrete posts among others.                   Defensive swimming is also another skill learned by the rescuers. This helps in keeping themselves safe. Working as a team is also another highly regarded skill that a person should possess. Working as teams helps the team achieve their objectives very first.                   The equipment carried during the rescue process includes megaphones and whistles which assist in communications, ropes that would be used in pulling people to safety places and extra life jackets that would help keep them warm. In addition, they also have lanterns and flares for staying in touch.                   What are some of the major and pressing considerations to consider when dealing with this disaster scenario? What are some hazards that will need to be assessed and overcome? Who will need to be warned or evacuated? Will transportation and shelter arrangements need to be made?                   There are major considerations that should be considered when dealing with floods. The considerations include studying the flood frequency, the length of inundation and the effects of flood and role of mitigation in controlling the flood (Strahler, 1973).                   In controlling floods, there are hazards which needs to be assessed. Gathering the hydrologic data directly from the nearby rivers is always very essential even though it might be time consuming. When data have been collected for quite a long time through stream gauging, then models can be used in coming up with statistical frequency of any given flood events. The importance of hazard assessments that are found based on the remote the remotely available sensing data, field observations and damage reports is that they can be used in instances when quantitative data is not available.                   As mentioned earlier, the importance of determining statistical frequency is that it’s helpful in determining their probability. In areas without records for a long period of time, the assessments are always very difficult.                   The people that stays near rivers or in areas that are prone to floods needs to be warned or evacuated depending on the situation of the flood. Those that stay in areas that are highly prone to floods should be evacuated. When distances that should be travelled are long, then transportation and shelter provisions ought to be made available to the affected people.                   List the steps that would need to be taken starting with the most pressing needs down to the final details. How will emergency medical care be distributed? Will mass triage need to be established? Will the affected area need to be cordoned off?                   The steps taken in helping solve or reduce floods and its effects include what is commonly known as the 3M approach. It involves Measuring Mapping (Schumann, 2011) Modelling                   Failing to do what should be done on time has always thwarted the efforts of several governments, or organizations in coming up with a long lasting effect concerning floods. Complete protection from floods might however be hard but under good preparations, flood evasion is easy. The above listed points starts with planning. Prolonged warnings always makes people to be ready and hence helps them keep their belongings safe (Moore, 2004).                   Emergency medical care to people affected with floods is very important and so is its distribution. The medical care equipment can be distributed through the use of helicopters in areas where other means of transportation is impossible. In instances where the flood is not extreme, then the drugs are distributed by the medical officers or the volunteers.                   Mass triage needs to be established in areas where the flooding effects were extreme and a lot of people are affected. Areas under flood are likely to pose a higher threat for individuals to contract water borne diseases and hence the need for mass triage. Cordoning off an area might also be necessary so as to differentiate the flood infested areas from those that are not. Cordoned off areas are not allowed to be reached by others unless the flood subsidises. Why is emergency management so important during this phase? Could an unorganized response actually lead to more confusion and chaos? How can resources and personnel be allocated efficiently with a central command post?                   Emergency management is important in each and every stage in disaster management. However, its importance is very vital during this stage because of the following reasons. Emergency management helps overcoming the emergencies because there is always a plan for it. With a good plan in place, all is possible. Secondly, emergency management helps in knowing the best way to deal with any problem should it arise. Having a survival kit is also another way through which emergency management helps an individual during occurrences like the flood. Inside the kit there are materials that are necessary in overcoming the emergency (Haddow, Bullock & Coppola, 2008).                   Confusion and chaos arises in situations where after an emergency, there is unorganized response from the management team. This always comes as a result of lack of emergency management tips.                   Having a central command post during emergencies like floods is very healthy in tackling the problem at hand efficiently. The stakeholders involved in helping solve the emergency for example floods, always assemble in the command post and work cooperatively to successfully mitigate the emergency through implementing a single incident action plan. A unified command post helps in the following ways Allows for specialist input whereby only specialised individuals are allowed to work on what they can handle It authorises each stakeholder to have input about how they believe the emergency will be managed.                   Having the right command post therefore ensures that only qualified personnel are assigned certain tasks. This is because they are the ones with authorities on that field hence they can always deliver their best. What are the initial steps that must be taken before recovery operations can take place? Why is disaster recovery so important? Should we strive to make the area better than I t was before the incident?                   Recovery involves rebuilding the whole community so that the affected individuals, governments and other body can now work on their own as they resume normalcy as well as prevent them from future hazards (Clements, 2009).                   The following should be done before recovery operations can take place. The officials should get clearance to enter the site. The extent of the damage should also be looked at before starting the recovery process. Those planning to undertake the recovery process should also get professional advice. Command centre for the recovery effort should also be sought before embarking on the recovery process. Another important aspect that should be looked before starting the recovery process is establishing security procedures for the recovery site. Lastly, deciding how the salvaged materials will be treated should also be looked before commencing the recovery process.                   Recovering from the trauma experienced during the floods might be quite challenging for many people. Therefore proper recovery steps must be undertaken to ensure people heal appropriately. Some of the recovery efforts include; giving medical aid, providing relief which comprises of food, water etc., clearing up the area, rebuilding damaged structures, reopening schools, businesses and all those places that were affected. The disaster recovery is so important in that it attempts to bring the affected people back to normalcy. People recovering from disasters always tend to have negative views so through the use of recovery process, they are made to appreciate life once more.                   The recovery team should endeavour to make the area a better place than it was. Leaving an area in the same or worse state than it was before makes people have bad feelings about such cases. Hence, the need for making an area a better place than it was before.                   How can the public or non-profit organizations assist in recovery operations? Should volunteers be sought and utilized? How could public donations be collected? How could debris be recovered and removed?                   The public and the non-profit organisations have been used in recovery operations. The non-profit organizations serves as health care providers, emergency shelter operations, and search and rescue team. Furthermore, they offer psychological training, as well as emergency communications. The public may also be used in assisting the affected group through being with them together. This always makes such people feel appreciated. They always feel that people are together with them even in their predicaments. The role of the public and non-profit organizations like churches cannot be underestimated.                   So as to make the recovery process a success, volunteers should be utilised. Volunteers are people who are willing to offer certain assistance at no pay. These volunteers might have dealt with similar cases before and are therefore more suited to serve and help the affected people.                   Those in the team should however strive to know the real volunteers. Some may volunteer with sinister motives. These people always lower or reduce the rate at which recovery process is achieved. Such people always make use of the vulnerable condition of the affected people for their own selfish gain. This vice however should be condemned.                   Public donations are very helpful in helping people recover from floods and its effects. People affected by floods needs food, quick medical attention and other basic necessities. The donations from the public if not collected using the right channels, might end up not helping in the intended purpose. Special bodies should always be put in place to man the public donations.                   Prompt cleaning of debris remains after the floods prevents odors, diseases. Contamination from run offs and many more. The following are some of the methods that are used to remove debris. The vegetation should be disposed of correctly. They should be handled in a manner that prevents draining into streams, ditches and other surface water sources (Lamond, 2012).                   Structures that are destroyed should be managed by the property owner and contractors if the floods affected construction sites. Sediments should also be discarded as solid waste.                   Whenever sewage is encountered during the debris disposal process that waste does not necessarily need to be separated. It should be disposed at a landfill mixed with other debris from the flood.                   Is the management of public relations crucial during the recovery process? How could information be relayed to the public to assure them that everything that needs to be done is being done? How could some of the survivor’s mental health have been affected by the disaster? Should crisis counselors be sought to deal with the survivors and victims of the disaster?                   The management of public relations is very important during the recovery process.                   Good public relations enhances good recovery. When there is poor public relations, there is less that canbe done to quicken the recovery process. Consoling affected people is of utmost importance during the recovery period. The people who have been affected by floods needs to be always encouraged that all is well and that help is always underway.                   Leaving people in conditions whereby they are not informed promptly, panic always arises. The best way to inform the public that all is well is by using leaders who they trust. Information which comes from a more authoritative person or a person who is experienced in a certain field holds more waters than information being rumored.                   The mental health of flood survivors may at times be affected. This is mainly in instances where the floods were so much and it caused serious destructions. The survivors might have seen some of their family members drown as a result of the floods. Sometimes, they themselves might have been rescued from death narrowly.                   For such people to heal completely, they need the services of a crisis counsellor for them to recover completely. The crisis counsellors are trained in dealing with problems like these and so they help the affected in overcoming the challenges they face.                   How important is it to promote a culture of vulnerability reduction to prevent disasters from occurringin the first place or at least mitigating their consequences if they do occur?                   Vulnerability is a set of conditions which results from physical, economic, environmental and social factors that increases a person’s susceptibility to the effects of the hazards.                   Promoting the culture of vulnerability helps in preventing disasters as well as mitigating their effects. This is due to the fact that the culture of vulnerability makes people aware of the problems they are facing. When one is aware of whatever he or she is undergoing, then he or she becomes prepared for anything. Being prepared means that solutions to problems can always be found before it’s too late.                   Apart from making people aware, people are also have strong coping capacity. They are always aware and so they can cope as required hence helps in preventing the disaster.                   How can technology be harnessed to smooth the recovery process? What are some tools available to emergency managers for recovery operations? Could the lessons learned from this disaster response and recovery be used in the future to better help communities respond to and deal with a disaster? What are some new and possibly unexpected threats that could arise in the future?Technology can be used to create tools that will lead to faster healings. The recovery process for it to be successful, technology must be used well. With the appropriate technology in place, transportation of medicine, staffs and other essentials that are needed will be availed easily.                   Tools available for use by emergency managers during the recovery process includes weather sensor and satellite, fibre optics, phones video, medical equipment. The lessons learnt from this disaster response are very helpful in dealing with future occurrences. The response when dealing with flood can be used when dealing with other types of floods. Some of the possible threats that are likely to occur during dealing with floods is the network problem. When floods occur, network connection is always tampered with. This happens to be the unexpected threats in when dealing with floods. Network unavailability hinders smooth communication. References Clements, B. (2009).

Multiculturalism

   The Canadian government has sought to have multiculturalism evolve in the Canadian community so as to seal the ethnic loopholes which lead to racial and social injustices based on race, caste and various backgrounds. The policies are meant to undo all aspects of discriminatory perceptions in the Canadian diverse community. The success of multiculturalism is limited. However it is a challenge to the history of social cohesion.Cohesion is what makes various cultural backgrounds harmonize their socio-economic interests. In her purge to identify social discontentment within various cultures in Canada Nakhaie (2006) explains social injustices through discriminative aspects of the Canadian professionals and other stakeholders of the Canadian authority. Socio-economic inequality shows ethno-racial minorities have better qualifications but don’t have confidence in their identity as successful Canadians (pg, 150).  According to Patricia Roy (1995) the intentions of multicultural ism were basically to break down discriminatory attitudes and cultural jealousies. She quotes the a Canadian prime minister and says â€Å"National unity in the deeply personal sense must be founded on confidence in one's own individual identity; out of this can grow respect for that of others (pg, 201)† However the essence of multiculturalism lacks virtue leading the Canadian society to a society of un-equal minority ethnic communities. Patricia seeks to create the picture of increasing racism in Canada.The three pillars on which multiculturalism is built do not really give multiculturalism any autonomy. It rather creates radical rationales within the diverse ethnic cultures in Canada. Racial identity leads to inequality in the social classes, work and rank and income classification leading to disintegration of social justice and equity (150). Nakhaie draws a picture wherein there is no cohesion but various segments of dis-satisfied multicultural society. Immigrants have poo r jobs and poor pay while certain ethnic and social groups enjoy employment and connections within political and social circles.She points out factors leading to this imbalance of social equity as time of immigration, race, period of immigration and language. The consequence of this diversity and complexity in advocacy of multiculturalism is embedded in principals of institutions like the civil service and the civil society as well as other vital institutions. Through them, confidence in the principals of multiculturalism might be augmented in the people however, there seems to be an ideological dilemma in trusting the principals in the immigrants.The Canadian government needs to be more versatile in making these institutions of governance compliant to the principals of multiculturalism through embarking and practicing social justice, equity and equal distribution of power and opportunities to all Canadians in-spite of their race, language or origin. Through this, confidence in the principals of a diverse culture will be embraced and the populace will be happy to identify with a diverse Canada. However, current practices have led to difference in opinion about personal identity in various immigrant societies. As such personal ideology and perception on the essence of cohesion within a multicultural society with apertures of unequal opportunities and social classes (Nakhaie, 2006)Nakhaie is pinpointing the limitations of multiculturalism in Canada as a result of pervasiveness of an individual’s ideology about the difference in equitability of opportunities and social justice. Canadian government officials do not recognize professional background of immigrants leading to immigrants taking lower classification jobs.About 88% of these people learn in Canadian institutions but only 19% of qualified immigrants get jobs they are qualified for in Canada (Basran and Zong, 1998). Multiculturalism fails since most immigrants see discrimination as rampant. They bel ieve racial discrimination is rife through skin color, ethnic origin and the second language. Professional immigrants see no efforts to halt discrimination by the federal authorities.Identity as a Canadian regardless of admission to Canadian community legitimately is void in immigrants. This is seen through lack of immigrant voters in federal, municipal and provincial polls. Social and economic background leads to this minimal participation in the electoral process (154).   Efforts by minority groups in the civic level participate electoral processes is aimed at lobbying against discrimination and racial injustices (Nakhaie, 2006).This inequality has led to limitations in the implementation of multiculturalism policies. There is no sense of identity in many legitimate immigrants in Canada. The sense of belonging and attachment to Canada lacks due to multiculturalism’s inefficiency to integrate the diverse cultures of the society. However this is contentious since huge perce ntages of French speaking immigrants express attachment to their provinces. But English immigrants are less proud of their Canadian identity.  The contention of multiculturalism lies within the context of socio-economic achievements, lower minority group’s representations in the formal political circle. Native Canadians and those who pride in their early immigration to Canada feel multiculturalism undermines the Canadian identity. This forces them to seek to show and prove their rightfulness as the legitimate and older generation of Canadians. This has led to the prevalence of inequality in social equity, seen within the context of representation, participation and employment in Canada (152).Looking at assertions in her works, Nakhaie is emphatic on ideologies and policies. She say’s that â€Å"one can hypothesize that those who adhere to the ideology of individualism, privatism and corporatism would tend not to support racially targeted policies, believing instead that racial minority members are responsible for their own misfortune because of lack of talent, motivation and handiwork (153).† This is the cause of inequality in social justice regardless of policies that pit multiculturalism as essential to the integration of the society.   Despite well intended policies multicultural cohesion is not achievable due to discontent to social injustices and inequality making Canada a racial society. Nakhaie argues that these policies do not suffice to convince the society of their equal opportunities.The minorities feel they are not equal to other Canadians who pride in their culture and representation. The state polices are clear on representation. Government policies are clear that every Canadian should enjoy fundamental and unalienable rights all which he cannot be deprived by any body (Nakhaie, 2006). This has led to ideological differences about the need for the â€Å"equal opportunity† policies while the state takes them for gra nted.Nakhaie says that â€Å"this taken for granted-ness seems to contradict state attempts intended to eliminate or reduce inequalities or to change the established conventions and the fundamental principals of social order. It therefore clashes with policies that address group-based systemic inequalities that are grounded in collectiveness or specifically support ethno-minorities (153).† This is the contention of ideological differences in identity and lack of success in multiculturalism.The identity and pride associated with Canadian background is what multiculturalism stands for, however, the void due to various ethnic groups identifying with Canadian identity is what leads to an inequitable society. Various social backgrounds, ethnicity and social class differ with each other leading to diverse discontent with what the ideology of one Canada. English immigrants do not take pride in being Canadian while the French immigrants pride in the Canadian identity. This makes the future of multiculturalism unclear since there needs harmonization and integrations of cultures to make an equitable society.Apart from policies, the state should put efforts in adding panache to multiculturalism. Nakhaie says immigration policies should offer satisfactory guarantee that equity and identity should be a right to every Canadian and that prejudices and any form of discrimination is liable to prosecution.A set of implement-able policies to enhance multiculturalism and create a cohesive society:Advocate for social networks within ethno-minority societies in Canada to enhance and improve their capacity in social capital, representation, and participation. This will improve their representation, involvement and participation in the Canadian economic and civil society Advocate institutions practice of outreach missions to increase dissemination of information and policies to ethno-minority groups so as to enlighten and empower them about their rights and identity as Canadia ns who have rights like all other Canadians. Encourage minorities’ participation on political and other social activities which will invoke belief of belonging through active participation. Increase equity through equal distribution of all government resources, opportunities and other amenities to all Canadians so as to increase the notion of merit and awarding positions and other chances based on merit.ConclusionThe need for multiculturalism has been embedded on a clear policy of social equity and unity. However waning confidence in identity as Canadians within the minority cultures has made the need for multiculturalism to lack value.

9 preguntas a turistas en control migratorio de EE.UU.

Turistas y personas de negocios que llegan a Estados Unidos pueden esperar que los oficiales de control de paso migratorio de la CBP les pregunten una serie de cosas para decidir si permiten su ingreso al paà ­s. En el paso migratorio tambià ©n se verifica el pasaporte y la visa o ESTA –en el caso de pertenecer a un paà ­s del Programa de Exencià ³n de Visados– y se cotejan con el programa TECS de la computadora del oficial migratorio. Ademà ¡s, se tomarà ¡n los datos biomà ©tricos del solicitante a ingresar a Estados Unidos. En este artà ­culo se informa de cuà ¡les son las 9 preguntas mà ¡s frecuentes en el paso migratorio y cuà ¡les son las respuestas correctas, asà ­ como quà © puede pasar y cuà ¡les son los derechos que aplican en la frontera de Estados Unidos (terrestre, marà ­tima y de aeropuertos). 9 preguntas preguntas frecuentes en el paso migratorio de EE.UU. El oficial de migracià ³n puede preguntar lo que estime conveniente, pero las que se enumeran a continuacià ³n son frecuentes. Una de las mà ¡s comunes es preguntar cuà ¡l es la razà ³n de la visita a Estados Unidos. La respuesta debe ser acorde con el tipo de visa o documento con el que se solicita el ingreso a EE.UU. Asà ­, si se tiene una de turista B1/B2 o una autorizacià ³n conocida como ESTA, la respuesta es turismo, negocio o atencià ³n mà ©dica. Es absolutamente equivocado contestar que la intencià ³n es buscar trabajo o contraer matrimonio. Otra pregunta frecuente es dà ³nde se va a alojar. Se puede llevar impreso el nombre y direccià ³n del hotel, si ese es el tipo de alojamiento. Si se va a estar viajando, tambià ©n es perfectamente và ¡lido contar cà ³mo se piensa viajar y los planes que se han hecho para reservar alojamiento, aunque no es necesario tener absolutamente todo cerrado ya que puede haber cambios en el caso de, por ejemplo, planear un tour por carretera. En todo caso, tener en consideracià ³n que, en ciertos casos, hay que notificar los cambios de direccià ³n del lugar de estancia. Tambià ©n se pregunta a quià ©n va a visitar. Es absolutamente normal visitar amigos o familiares. Sin embargo, si estos està ¡n en situacià ³n de indocumentados se recomienda no mentir a los oficiales de migracià ³n bajo ninguna circunstancia, pero tampoco crear una situacià ³n difà ­cil para los amigos o familiares. Tambià ©n se pregunta cuà ¡nto tiempo se va a quedar. Es fundamental tener claro el tiempo mà ¡ximo de estancia legal. Si se ingresa con una visa, es posible pedir una extensià ³n o cambio de visa, si se cumplen todos los requisitos. Por el contrario, si se tiene una ESTA, se tiene que salir del paà ­s antes de los 90 dà ­as y no es posible, bajo ninguna circunstancia, ampliar ese plazo. Tambià ©n se pregunta cuà ¡nto dinero se trae y si se tiene algo que declarar. Se trata de no exceder el mà ¡ximo legal sin declarar y tambià ©n de asegurar de que no se va ser una carga para el gobierno de los Estados Unidos. No hay que llevar mucho dinero en efectivo, ya que se pueden llevar tarjetas de dà ©bito o/y crà ©dito. Otra pregunta clà ¡sica es en quà © se trabaja o quà © se estudia. Responder lo mismo que se ha dicho al solicitar la visa. Asimismo, si se llega por avià ³n es habitual que se pregunte desde dà ³nde se vuela. La respuesta correcta es la ciudad desde donde despegà ³ el vuelo pero si se ha hecho escala, se puede contar el viaje completo. Otras preguntas que hay que esperar es si se ha visitado previamente los Estados Unidos. En este punto tener en cuenta las consecuencias de viajes anteriores en los que no se salià ³ a tiempo del paà ­s, y tambià ©n  cuà ¡nta frecuencia se està ¡ ingresando.  ¿Quà © puede pasar a continuacià ³n? Pueden suceder varias situaciones, que dependen de la decisià ³n que tome el oficial migratorio. En la mayorà ­a de los casos, la persona extranjera serà ¡ admitida a Estados Unidos, aunque es posible que debe pasar por una segunda inspeccià ³n, que es lo que popularmente se conoce como el cuarto. Si se ingresà ³ con visa de turista, se puede consultar el I-94 –registro de entrada y de salida– para tener claro cuà ¡ndo se debe salir del paà ­s o para pedir una extensià ³n de la visa. Tambià ©n es posible que se le permita entrar aunque no tiene los documentos necesarios. En estos casos se dice que se la ha dado un parole. Es decir, se permite el ingreso aunque no se cumplen los requisitos. Por ejemplo, en los casos de peticià ³n de asilo despuà ©s de mostrar miedo creà ­ble en una entrevista. Tener en cuenta que ya no es posible solicitarlo en la frontera por razà ³n de miedo a las pandillas o violencia domà ©stica y que en estos momentos es habitual que el solicitante de asilo en la frontera espere por meses e incluso aà ±os detenido hasta que se resuelve su caso. Ademà ¡s, en casos extraordinarios, la persona serà ¡ arrestada (aprehendida), como es el caso de que està © buscada por un delito por las autoridades. Y, finalmente, la persona extranjera puede ser regresada al paà ­s en el que se inicià ³ el viaje. La razà ³n es que se considere que es inadmisible para ingresar a EEUU, que es inelegible para la visa que tiene o para la ESTA, o que los documentos son falsos. Como las situaciones de la prohibicià ³n a ingresar son muy variadas, es importante saber si se coloca un I-275 en la visa, o se realiza una expulsià ³n inmediata o, incluso, se permite al extranjero retirar su peticià ³n de ingreso a EE.UU. Todas esas situaciones tienen consecuencias diferentes a la hora de intentar posteriormente regresar por lo que conviene tener claro quà © realmente pasà ³ y por quà © se denegà ³ la entrada. Derechos en el control migratorio de EE.UU. En los puertos de entrada, conocidos en inglà ©s como POE y que puede ser un aeropuerto, un puerto marà ­timo o una frontera terrestre, hay que pasar dos controles, primero el migratorio y luego el aduanero. En los POE, que tienen todos consideracià ³n de frontera, no està ¡ permitida la asistencia legal de abogados y, en contra de una opinià ³n errà ³nea muy extendida, lo cierto es que no aplican las protecciones de la Constitucià ³n. Por lo tanto, si asà ­ lo consideran necesario, los oficiales de la CBP pueden tener acceso a nuestros telà ©fonos, cà ¡maras, computadoras y otro material digital.
