Sci-fi. Inception science fiction film Essay Example | Topics and Well Written Essays - 1250 words

Sci-fi. Inception science fiction film - Essay Example Subsequently, Inception went on to win several significant awards, but most notably the Academy Awards. The film projects three principal themes; dreams, recursion and, suicide. Inception questions the wisdom of accessing too much information from a person’s subconscious. The movie revolves around a thief, Cobb, who steals precious information from the minds of his targets. He does this by projecting into their respective subconscious and sourcing the essential information. It is during one such projection, Saito’s mind, that he is defeated in retrieving the required information, but ends up being hired for a job whose gains will see him able to return, safely, to his family. The picture expounds on the strain that was faced in the new task, Fischer’s subconscious. Amidst all this, Cobb has to battle his emotions pertaining to his wife’s suicide, which disturbs and delays waylays him, within the target’s subconscious. Ultimately, Ariadne shoots Mal, thus, saving Cobb. The mission is successful, and the protagonist’s return to his family is made plausible. Very few movies have explored this unique theme of projecting into people’s dreams. The movie illustrates this process in a manner previously rarely seen. The main audience of this film happens to be adults. This arises from the fact that its themes and intricate details can only be fully grasped by adults. Science can best be defined as a realistic speculation of future scientific and social advancements. This is realized via deep understanding of the scientific world. It requires a considerable amount of imagination and existence of the element of plausibility. It is imperative for Science fiction movies to be characterized by conflict, believability and excellent visual effects. Inception is characterized by all these three elements. The Dreams are a core theme throughout the entirety of the movie. It entails an intricate web of interconnected dreams. A dreamer is the individual in whose dream the action exists. Subsequently, each level of dreaming must have its own dreamer. Each dream must have its subject, who is the individual whose subconscious is the source of information. Unless something bizarre happens, the dreamer is usually unaware that he is dreaming. However, in the event the subject realizes he is dreaming, his projections are often violent towards the dreamer. To avoid such eventualities, the work of the architect is to make the world as real as humanly possible. In the dream world, when an individual committed suicide, it meant a safe passage to reality. This was often the avenue of choice for a majority of characters in the film when at wits end. However, in the Fischer mission, this avenue is unsafe as no guarantee exits on its safety and certainty. The team realizes that death, in that particular dream state, will usher them into limbo where one is prone to insanity. Throughout the entirety of the film, the protagonist is haunted by the first suicide in the films beginning. His wife, Mal committed suicide while attempting to return to her children in real life. She had believed that she was still in her dream while in fact she was in the actual world. The third prominent theme is that of recursion. This is evident in both conceptual and visual features. This is exemplified by a dreamer is dreaming a dream. This creates the concept of levels as sociated to levels. A dreamer first dream in the first level, then another dreamer inside the first dream initiates another dream. Thus, two dreams now exist, and events are now taking place in the second level: often, the inner stories inside the dream in a dream overwhelm the real world framing. These interconnected dreams are the core concept of the film. Recursion enables the individuals

Enhancing the Quality of Services and Processes through Strategic Essay

Enhancing the Quality of Services and Processes through Strategic Management - Essay Example The paper tells that the contemporary hospital presents a complex inter-relationship of responsibilities in addition to objectives that need to be balanced to enhance service delivery. Hospital executives constantly focus on internal aspects such as recruitment, acquisition of facilities and equipments as well as provision of healthcare to patients. The Arnold Palmer Hospital is evocative of a scenario whereby top management mainly focuses on patient satisfaction as an end in itself. Patients can be awarded valuable gifts of up to $200 by the hospital employees in case they complain reasonably. As much as it is necessary to apply a patient focused approach to management of the hospital, it is also necessary to take in to consideration the external factors that influence the strategic position as well as the day to day operations of the facility. The hospital managers need to focus on satisfying the needs of employees, patients and other stakeholders who represent diverse interests. S trategic management involves designing, implementing and evaluating managerial decisions so as to be able to accomplish an organization’s long term objectives. It also involves systematic analysis and evaluation of internal and external factors so as to be able to make decisions for the future of the organization. Liebeskind views strategic management as a process whereby managers decide on the mission, vision and objectives which they would like to be achieved over a specified time limit. They develop policies and plans to be followed by employees so as to achieve the mission and objectives. After developing plans, they provide resources that facilitate the implementation of policies and after a specified time, they evaluate whether the goals have been accomplished. Mission statements help managers to set the company direction (Collis & Montgomery 2001). Various theories have been put forward by scholars regarding what strategic management entails. Mintzberg’s theory helps managers to interpret the process of strategic planning and be able to plan even when internal or external factors influence the accomplishment of daily activities. Arnold Palmer Hospital’s management can accomplish its strategic objectives if Mintzberg’s approach is adopted (Mintzberg, 1990). The management of this hospital needs to design, plan and position the hospitals operations in consideration of the future. The designing process according to Mintzberg involves with strategy development whereby the management evaluates the strengths and weaknesses of the institution against the opportunities and threats which are among the external factors affecting its efficiency. Based on the result, the management is able to formulate a strategy which addresses the shortcomings while trying to maintain equilibrium between the external factors and organizational performance. The organizational strategy needs to be understood and implemented by all staff members while on the other hand. Flexibility in strategy is important to ensure that the organization maintains competitiveness in the constantly changing operating environment (Mintzberg, 1990). Planning involves formulating a strategy with a time line, goals and objectives, which are stated and formulated to help achieve the organizational objectives. A plan will provide the hospital’s management with direction through clearly stated objectives. Planning is a continuous process as variables keep changing hence the need for management to be ready for changes throughout the organization’

Introduction to Alcohol Addiction Theories

Introduction to Alcohol Addiction Theories Alcohol Addiction Addiction in general, though this paper will focus on alcohol specifically, is characterized by a chronic relapse state that embodies key elements, such as the compulsion to seek out and use the drug, the inability to control the amount used, and a negative emotional state when the substance cannot be accessed (Gilpin and Koob, 2008). Alcohol consumption evolves from impulsive to compulsive through repeated binging, withdrawal, and craving cycles, which cause neuroadaptations (Cui et al., 2013; Koob, 2013). Research on the neurobiology of addiction has focused on the positive reinforcing effects and the activation of the mesocorticolimbic dopamine circuit being the sole motivator. The mesolimbic system (the primary reward circuit) projects from the ventral tegmental area (VTA) to the nucleus accumbens (NAcc) and utilizes dopamine as its main neurotransmitter (Gilpin and Koob 2008). This circuit helps shape incentive salience, better known as the wanting or desire for alcohol (Robinson Berridge, 1993; Berridge, 2007). Oral ethanol self-administration is reduced by the administration of dopamine and NMDA receptor antagonists into the nucleus accumbens (Rassnick 1992). Weiss et al measured dopamine levels in the extracellular fluid of the NAcc and showed alcohol ingestion or even the anticipation of alcohol causes an increase in dopamine (Weiss et al. 1993). However, Rassnick also demonstrated that positive reinforcement alone does not motivate alcohol consumption while using a 6-hydroxydopamine (6-OHDA)-induced lesions of the mesolimbic dopamine system did not block alcohol self administration (Rassnick et al. 1993). Even in the presence of administered methylphenidate, subjects experiencing alcohol withdrawal show lowered levels of dopamine by 50-70%, as compared to controls; withdrawal causes decreases in dopamine function and the neuroadaptations that lead to a hypodopaminergic state during withdrawal (Karkhanis 2015 CIE ethanol exposure reduces presynaptic DOPAMINE NEUROTRANSMISSION IN THE MOUSE NUCLEUS ACCUMBENS; Volkow et al. 2007 Profound decreases in dopamine release in striatum in detoxified alcoholics: possible orbitofrontal involvement.). In the early stages of alcohol use and abuse, positive reinforcement acts as the main motivating factor in alcohol-drinking behavior. However, at some point chronic alcohol exposure causes a shift from alcohol use to alcohol dependence that parallels the switch from positive reinforcement to a mixture of both positive and negative as the motivating factor behind alcohol use; this is caused by neural changes, or plasticity, that chronic alcohol exposure elicits (Gilpin and Koob, 2008). There are three widely recognized stages of alcohol use that overlap and ultimately contribute to the progressive transition from alcohol use to alcohol dependence. They are: 1) binge and intoxication, 2) withdrawal and negative affect, and 3) pre-occupation and anticipation, better known as craving (Volkow et al., 2016). Neuroadaptations within the addiction circuitry and the progressive transition from alcohol use to dependence hinge on the repeated cycling of these three stages. Three phenomena contribute to the progression of alcohol use disorders and the shift from positive reinforcement to both positive and negative reinforcement as motivators for alcohol use. They are sensitization, tolerance, and withdrawal. Drug sensitization, which is the opposite of tolerance, refers to the individuals increased stimulus that occurs when the same amount of substance is taken as before; this leads to the cue-induced craving. When it takes more alcohol to achieve the same level of intoxication, as a smaller amount used to, then the subject has developed a tolerance. Withdrawal is the outward presentation of neural changes and happens when adverse effects occur in the absence of the substance, such as insomnia, delirium tremors, anxiety, and seizures. As these elements of addiction repeat, the disease progresses and spirals more out of control (Gilpin 2008)

Osteoporosis :: essays research papers

Bone Case Study 1.  Ã‚  Ã‚  Ã‚  Ã‚  A bone mineral density (BMD) test measures the amount of mineral concentration in a specific region of the bones in order to determine a persons bone strength or density and their risk for fractures. 2.  Ã‚  Ã‚  Ã‚  Ã‚  The physician uses the BMD test in conjunction with a patient’s history to determine the patient’s risk of Osteoporosis. Osteoporosis is a disease that is characterized by thinning, weak bones. Bone loss is actually a normal event in the human body. We loose bone when cells (osteoclasts) release stored salts (calcium, phosphorous, magnesium) from the bone into the blood stream when dietary intake is not providing adequate amounts. Typically (at least until age 30) we have other cells (osteoblasts) that come in and repair, repair and build lost bone. Osteoporosis occurs when the osteoclasts are working faster than the osteoblasts. Eventually the osteoblasts fall further and further behind leaving thin and brittle bones. 3.  Ã‚  Ã‚  Ã‚  Ã‚  Results for the BMD test are given as T-scores and Z-scores. The T-score compares the results with a healthy young adult of the same gender and the Z- score compares it with an individual of the same age and gender. A positive or normal result of the BMD would be 1 standard deviation (+1/-1) of the T-score mean. A result of 2.5 or greater below the mean is considered to be osteoporosis. 4.  Ã‚  Ã‚  Ã‚  Ã‚  Osteoporosis is the diagnosis for a person whose score falls 2.5 standard deviations below the mean. If her history reports findings of bone fractures that are osteoporosis related, her diagnosis may be that of severe osteoporosis. 5.  Ã‚  Ã‚  Ã‚  Ã‚  When diagnosing a patient the most critical information will come from the patient’s history (familial and personal). This information allows a caregiver to assign specific risk factors associated with certain diseases which help determine a person’s chance of developing a disease as well as measures that can help prevent further progression. It was important for the doctor to know if Janice ‘s diet included adequate amounts of calcium and vitamin D. Both play key roles in bone density, calcium is needed to maintain bone strength and vitamin D is needed for calcium absorption into the blood stream and reabsorbing in the kidneys. Hormone replacement therapy plays a role in the prevention of osteoporosis because it restores estrogen levels and helps to slow the bone thinning process (HRT and its osteoporotic benefits can be offset by possibly increasing risk for other serious diseases).

Masters degree application essays

Essay 1 (1,000 words)Describe your career progress to date and your future short-term and long-term goals. How do you expect an MBA to help you achieve these goals, and why is now the best time for you to join our program?Content:A master is ever, but a learner, goes an old Chinese saying. The same is true for any man, no one may call himself a master who believes he knows all there is about his subject. In today’s ever changing, globalized-world, a true master must continue learning if he is to remain competitive. I do not claim to be a master trader. However, I too believe in the value of higher learning.After graduating high school, and having worked for two summers in a large investment bank, I started my own investment management firm at the tender age of 19. With the help of a few angel investors who entrusted me with $50,000 each, I not only significantly grew their investments but the profits from my business were sufficient to fund my four years of university studies AND finance my travel to several countries mentoring high school children and visiting mentoring programs outside of the USA.In my travels I raised money for the university which I attended. During and after my tenure in the university I was served the role of their European ambassador. I have also done the same work for several non-profit organizations such as ABC, DEF, and GHI, all of which focus on the mentoring and training of leadership skills to high school students for them to become better community leaders.My leadership in a community oriented NGO is different from the type of leadership I exercise at work. In my business the objective is to maximize the value of our investor’s money. Success is measured by the growth in their investments and the increased trust this generates. By comparison Ulpan is about giving educational opportunities to predominantly Jewish high school students. ORT is very similar in its goals. My hard work is rewarded by seeing our beneficiari es motivated and eager to take the path of higher education as a means to success. The drastically different metrics of my community service broadens my horizon as a leader.My current job trading at an investment firm, I improved their existing procedures for monitoring our market positions during volatile periods and developed a â€Å"pop-up† system to handle trades more efficiently and make decisions faster. I made an immediate impact. We are now able to monitor approximately 10% of our daily volume and take property risk management decisions in a fast and volatile market where time is of the essence.Using my native insight I found an opportunity for growth in the company. However, I faced the inertia associate with any kind of meaningful change. Despite the cost of lost, personal, man hours. I pushed my plan past the bureaucracy offering potential benefits that far outweighed the costs of the project. Taking responsibility for my unpopular stance, my assumption of leadersh ip led to my taking the risk of losing my job if the project failed. With a lack of popular support a failure to improve profits or a net loss would severely afflict my reputation in the firm and in the industry. However I stood my ground and pursued what I knew was a good idea. As a result, I was now looked upon as a leader that brought positive change to my firm.Even in my early youth I understood that my current level of learning was not enough. By practicing what I had already learned and working in the field of my choice I was able to expand my practical knowledge. However, I also believe that practical experience must go hand-in-hand with expanded theoretical training. Hence, I desire to obtain an MBA.My ultimate goal is to head a financial firm which will manage wealth for non-profit organizations to help them grow at a faster pace and be able to focus more on their advocacies in their respective communities rather than struggling to raise funds and managing assets, tasks tha t are far from their competencies. An MBA will help me achieve this dream by expanding my horizons and making me even more capable of competing for marginal gains and derivatives that have become harder and harder to obtain.In the United States, this is more common with university endowments and major non-profit organizations which have asset managers steering the funds to competitive investment returns. However, in Europe and Asia, this almost doesn’t exist. As a result, most European and Asian NGOs are in quandary trying to husband their funds effectively but at the same need to disburse it for their projects.I want to bridge this gap and bring financial management expertise to global non-profits and help them become even stronger. By my efforts, I will allow the non-profits to bring better service to the community, faster, and more efficiently. An MBA will enhance my skills and improve my ability to maximize the wealth of these organizations and spare them from the having to worry about raising funds.I take personal pride as I have been involved in my own community, mentoring high school students, helping them make decisions about their future, whether it be academically, professionally or personally. My work with several non-profits, coupled with my financial expertise as a trader can bring tremendous change to both the financial and non-profit industries.I want to create this new niche, a new service and make the non-profit sector even more influential. This is my dream. This is my goal. And this brings my two passions, the financial market and community service, into one, gratifying job. With an MBA, the skills learned, the network I have access to, I can realize this dream. Now is the time to go for it. My hopes are high and my time is neigh. I am young, eager and hungry for wisdom, wisdom I will gladly put to good use.Essay 2 (500 words)Tell us a situation in which you were an outsider. What did you learn from the experience?Content:When I first joined my current firm an archaic system was used to monitor trades. Everyday there were orders passed through our desk. This resulted in too much effort diverted to time consuming monitoring work and we ran the peril of having to make risk management decisions on the spot. Often we would have to wait until the end of the day to review our book and take action on hedging ourselves.This manner of operations was untenable, in the volatile industry I was in, up to the minute decision making was vital to success or failure. To improve this, I immediately proposed a â€Å"pop-up† window function that takes snapshots of all the vital information we would need   to know about the orders passing through our desks. For example, trade size, currency traded and margin level are included in this data. This drastically improved the way the trading desk monitors transactions, especially in times of extreme market volume and volatility.Regretfully, I encountered considerable resistance f rom my peers and upper management. Our technical department said it would take months to develop the proposed system because they were overloaded with work and writing the script would take weeks. Stephane, our head of trading appreciated my initiative but failed to prioritize it. Fortunately, our managing director, Nick gave his approval for my leadership in this project.With his approval in hand, I put pen to paper, outlining the method which I wanted implemented and convinced our technical department to prioritize the project. I wrote them a memo stating very clearly that upper management fully supported my efforts and I emphasized that successful implementation would boost profits on a daily basis. This in turn would put the technical department in the limelight for having developed such a useful tool.My inspirational leadership conscripted the aid of our technical department and the pop-up was developed in one week and was an immediate success. We are now able to monitor approx imately 10% of our daily volume, which amounts to $150 million, and take proper risk management decisions in the fast, volatile market where time is of the essence. Based on my estimates, this results in a cost savings of about 4% a month which redound to increased profits.Using my native insight I found an opportunity for growth in the company. However, I faced the inertia associate with any kind of meaningful change. Despite the cost of lost, personal, man hours. I pushed my plan past the bureaucracy offering potential benefits that far outweighed the costs of the project. Taking responsibility for my unpopular stance, my assumption of leadership led to my taking the risk of losing my job if the project failed. With a lack of popular support a failure to improve profits or a net loss would severely afflict my reputation in the firm and in the industry. However I stood my ground and pursued what I knew was a good idea. As a result, I was now looked upon as a leader that brought pos itive change to my firm.Essay 3 (500 words)Where in your background would we find evidence of your leadership capacity and/or potential?Evidence of my leadership potential can be found in my work as project organizer for Ulpan in Warsaw, Poland and The ORT Foundation in Geneva, Switzerland. Ulpan provides educational opportunities for high school students, who are predominantly Jewish, who seek a better education in the United States. The ORT foundation provides mentoring to high school students to help them decide on career-paths and how to go about realizing their professional dreams.I organized cross-border contact through mail and email correspondence, allowing young people to build and maintain connections with peers in the US. My accomplishments with these two organizations are integrally associated with me and very close to my heart. As a child, I was helped by a mentor, David, and with his help, have succeeded in pursuing my dreams with much confidence.NGO work requires out- of-the-box thinking and creative decision making. For example, bringing a Jewish teenager from the Warsaw ghetto and providing him with a scholarship to study in a University requires a wide variety of skills. First, the child must be motivated to make the most out of his talents. I must be inspirational and optimistic to provide the necessary motivation. Second, If the mentee still has areas of improvement I may be tasked with nurturing and uncovering his talents.Third, obtaining a scholarship will require taking with benefactors who may later become potential investors in the child’s future. This requires negotiation skills equal to that of a boardroom raider. Finally, my decisions require reflective hindsight because in many ways I am responsible to the benefactors for the success of their beneficiary. In the end nothing is more rewarding than receiving letters from the student that he is doing well in school and on the way to a bright future.NGO work is a challenging as a ny task on the trading floor. It makes the most out of my skills and encourages me to continue learning. My unique background as a trader brings a skill set that is not common in the Ulpan or ORT foundation, making my contributions even more valuable to these organizations. My background and insight have resulted in the foundation taking opportunities it might have otherwise not identified. Finally, because I am constantly learning my leadership in these foundations have given me valuable experiences in dealing with others that I can carry with me back to my day job,My leadership in a community oriented NGO is different from the type of leadership I exercise at work. In my business the objective is to maximize the value of our investor’s money. Success is measured by the growth in their investments and the increased trust this generates. By comparison Ulpan is about giving educational opportunities to predominantly Jewish high school students. ORT is very similar in its goals . My hard work is rewarded by seeing our beneficiaries motivated and eager to take the path of higher education as a means to success. The drastically different metrics of my community service broadens my horizon as a leader.

Atticus Finch as a Role Model

Atticus Finch as a Role Model Does your role model have a negative or positive impact on your life? Major of people has a role model they look up to and make every effort to be alike. Each person has a different perspective on a leader but in the book To Kill a Mockingbird by Harper Lee, Atticus displays himself as a hero being able to resolve situations with fairness for everyone and prevent the town from falling apart. Atticus' actions impact his children, his peers involved with the court case and the people of Maycomb. Firstly,Atticus Finch is a single parent that treats his kids, Jem and Scout as adults and tries to enlighten them on the outside world of Maycomb. There are many events that Atticus is involved in which displays him as a good role model. For instance, when Atticus gives Jem and Scout guns he tells them, â€Å"shoot all the blueJays you want, if you can hit'em but remember it's a sin to kill a mockingbird† (Lee 90). Atticus is a great role model as he teache s Jem and Scout that it is a sin to harm someone or something that is innocent.Atticus uses the example of a mockingbird because these irds only sing, therefore these birds should not be harmed. Atticus is an excellent father and a good role model to Jem and Scout as he teaches them good morals throughout the novel. Many people in Maycomb are prejudice and Atticus teaches Scout to think otherwise, as Atticus tells her miou never really understand a person until you consider things from their point of view†¦ until you climb in to their skin and walk around in it. † This shows Atticus is an open-minded gentleman that takes ones past history into consideration.These lessons develop Jem and Scout with knowledge o handle situations maturely that they encounter later in the novel. These are various explanations why Atticus is an effective role model to his children Secondly, Atticus Finch shows his protagonist values in his place of work and towards people involved within the c ase at the courthouse. No matter where Atticus is or the situation he is within, he keeps a positive attitude, while going through the trials and tribulations in the workplace.For instance when Atticus runs into Bob Ewell at the post office, the father of Mayella the victim of the case, Mr. Ewell is still suffering over the whole case, reacts by spitting in Atticus's face and threatens to kill him. Atticus responds by saying â€Å"l wish Bob Ewell didn't chew tobacco† (CH. 22). Atticus realizes that it is not worth it to fght Mr. Ewell and so he understands Mr. Ewell frustration and takes it without causing anymore anguish for Mr. Ewell. Also Atticus is a strong man, that despite losing the case in court he keeps his head high.While Atticus waits on his children after the case; Scout notices her father's demeanour and expresses to s, stating ‘Atticus was standing under the street light as though nothing happened his vest buttoned, his collar and tie were neatly in place †¦ he was his impassive self again' (CH. 22). Atticus stays strong for the town that came to support him and since he tries his best he is not ashamed; although this is unacceptable to send Tom to Jail without presenting evidence to show that Tom Robinson is guilty. It is not possible to win everything! As long as the effort put into the task was your best!Atticus Finch his role m Odel principles to the people involved xpresses in the case. Thirdly, Atticus is a perfect role model to the people of Maycomb. The Finch family is well known in the neighborhood due to Atticus' being kind and having relationships with several people in the town. For instance Atticus allows Jem and Scout to let Walter Cunningham attend dinner with his family since he comes from a poor family, and Atticus did business with Walter's dad whom still did not pay Atticus. Walter says â€Å"Atticus I don't know when I'll ever be able to pay you† (CH. ). Atticus is a reasonable an that decides Walter's dad will not pay him regardless will provide the Finch's food from the Cunningham farm. Atticus demonstrates that we do not have to be treated differently because of our race. Another reason is Atticus is willing to risk his life to help his neighbor. As Miss Maudie's house is burning and Atticus decides to go into the house to save Miss Maudie rocking chair which she loves so much (CH. 8). This kind Jester Atticus could have died from attempting to save Miss Maudie's rocking chair.Not Just anyone would go sacrifice themselves in a burning building ust to save a chair but because of this Atticus demonstrates to the townspeople he cares about them and is an excellent role model for the people of Maycomb. Is Atticus a negative or positive role model in the novel? People have to do extraordinary things to be represented as a role model but In to Kill a Mockingbird by Harper Lee, Atticus confirms that he is a successful role model by him teaching his children good moral values, working with peers involved in the court case, and impacting the lives of the townspeople.

Carta de invitación para sacar la visa de turista EE.UU

Carta de invitacià ³n para sacar la visa de turista EE.UU Las cartas de invitacià ³n se utilizan frecuentemente como parte de la documentacià ³n que se entrega a una embajada o consulado americano cuando se solicita una visa de turista para Estados Unidos. No es un documento necesario, pero sà ­ que es  frecuente  porque puede ayudar a que el oficial consular se decida aprobar la visa que se solicita. Pero es importante entender que, por sà ­ sola, la carta de invitacià ³n no es suficiente para obtener la visa, sino que es un elemento ms a tener en cuenta y para inclinar la balanza a favor del solicitante.   Asimismo, si no se presenta una carta de invitacià ³n eso no quiere decir que la visa no pueda obtenerse. En otras palabras, es un documento de presentacià ³n voluntaria que puede ayudar a obtener la visa. En este artà ­culo se informa sobre quià ©nes pueden escribir la carta de invitacià ³n, quià ©n es el destinatario de la misma, cul es el formato adecuado y quà © documentos adicionales se pueden incluir en apoyo de la veracidad de la carta. Quià ©nes pueden escribir la carta de invitacià ³n para sacar la visa de turista La carta de invitacià ³n no la escribe la persona que solicita la visa, sino otra distinta que es a quien se va a visitar en Estados Unidos. En este punto, es fundamental el estatus migratorio de dicha persona en Estados Unidos ya que determina si tiene capacidad para redactar este tipo de documento. Pueden hacerlo las siguientes personas: En primer lugar, los ciudadanos americanos, que debern acreditar tal situacià ³n mediante documentos como copia del pasaporte americano o del certificado de nacimiento en Estados Unidos. En realidad, cualquier documento oficial que pruebe su condicià ³n de estadounidenses. En segundo lugar, los residentes permanentes legales. En este caso, debern incluir con la carta una fotocopia legible por los dos lados  de su tarjeta de residencia, tambià ©n conocida como green card. Y, en tercer lugar, pueden redactar la carta de invitacià ³n los extranjeros que se encuentran legalmente en Estados Unidos  porque tienen una visa vigente. En este caso  debern adjuntar a la carta de invitacià ³n su certificado original de nacimiento, fotocopia de todas las hojas de su pasaporte y, si su visa estuviera en otro ya expirado, tambià ©n incluir copias de à ©ste. Si la visa est expirada pero se ha pedido su renovacià ³n, una copia de dicha peticià ³n. Adems de esos documentos los extranjeros con visas L1 de transfer entre sedes de una misma empresa  o H1  para profesionales debern incluir su à ºltimo I-797, una carta que reciben del Servicio de Inmigracià ³n y Ciudadanà ­a (USCIS, por sus siglas en inglà ©s). Por otro lado,  los migrantes que està ©n en situacià ³n de ajuste de estatus pendiente  se recomienda que envà ­en junto a la carta de invitacià ³n una copia del documento que pruebe tal situacià ³n, como por ejemplo el permiso de trabajo, conocida en inglà ©s como  EAD card. Por à ºltimo, tener en consideracià ³n que si la invitacià ³n se hace a favor de un familiar por razà ³n de matrimonio, como por ejemplo un suegro o un cuà ±ado, deber acompaà ±arse la carta de invitacià ³n con una fotocopia del certificado de boda de la persona que invita y fotocopia del pasaporte de su marido o de su mujer. Por ejemplo, si un ciudadano americano est casado con una mexicana y quiere invitar a su suegra a que les visite en EEUU con ocasià ³n del bautizo de su hijo deber incluir no sà ³lo prueba de su ciudadanà ­a estadounidense, sino tambià ©n de estar casado con su esposa mexicana y copia del pasaporte de à ©sta. Finalmente, los migrantes indocumentados no deben  escribir una carta de invitacià ³n. No facilitarà ­a la solicitud de visa del solicitante y, por otro lado, servirà ­a para revelar la situacià ³n de indocumentado de dicho migrante y datos importantes como, por ejemplo, dà ³nde vive. Adems, si una persona invita a sus padres a visitar Estados Unidos y esos padres tienen ms hijos en ese paà ­s, deber tambià ©n acreditarse el estatus legal de todos los hijos que viven en el paà ­s y no sà ³lo el del hijo que extiende la invitacià ³n. Destinatario de la carta de invitacià ³n para sacar la visa de turista La carta se envà ­a a la persona que se desea invitar y  no al consulado  o embajada que debe tramitar el visado. Este punto da lugar a mucha confusià ³n ya que es comà ºn creer que el consulado es el destinatario de esta carta. Sin embargo, esa creencia es equivocada. En todos los casos, la persona que invita debe enviar la carta a la persona invitada. Formato de la carta de invitacià ³n para la visa de turista para EE.UU. No hay una forma determinada que diga expresamente cà ³mo tiene que ser la carta. Es decir, cada persona puede escribir lo que quiera, pero utilizando un lenguaje formal, respetuoso y claro. Adems, deberà ­a seguir las siguientes pautas: Estar escrita en inglà ©s.  Incluir la fecha en la que se escribeNo olvidarse de firmarIdentificar expresamente  a la persona que se quiere invitar. Por ejemplo, si son padre e hijo, hermanos o simplemente amigos.Redactarla en una computadora e imprimir el documento.

Y es que los ciudadanos de los paà ­ses acogidos al Programa de Exencià ³n de Visas  pueden ingresar solicitando una Autorizacià ³n Electrà ³nica conocida como ESTA si llegan al paà ­s por avià ³n o llenando el formulario I-94 si llegan por barco o se presentan en una frontera terrestre. Como no necesitan visa, tampoco precisan de una carta de invitacià ³n.
