Políticas de inmigración en América Latina: el extranjero indeseable en las normas nacionales, de la Independencia hasta los años de 1930 (Estudios)

El artículo explora el surgimiento de la figura del extranjero indeseable en las legislaciones nacionales latinoamericanas, desde la Independencia hasta finales de la década de 1930, aproximadamente, de forma paralela a la política de inmigración en los Estados Unidos. Las restricciones sobre la entrada libre de extranjeros que establecieron las repúblicas, durante las primeras décadas de la Independencia, estaban relacionadas con el modelo del ciudadano idealizado. El análisis de los impedimentos para la entrada de extranjeros muestra cómo, durante el siglo XIX, el extranjero “deseado” fue definido cada vez más en contraste con los rasgos negativos de los “indeseables”, bajo el supuesto objetivo de “defender la nación”.This article explores the emergence of the figure of the extranjero indeseable in national legislation in Latin America, from independence through the late 1930’s, taking into account parallels with immigration policies in the United States. Restrictions on the free entry of foreigners, established in the nation-states during the first decades of independence, were based on the concept of the ideal citizen. The analysis of impediments to the entry of foreigners shows how during the nineteenth century the ‘desired’ alien was increasingly defined in contrast to the negative features of the ‘undesirable’ alien and was aimed at ‘defending the nation’

Regímenes de pertenencia nacional en Venezuela y la República Dominicana contemporáneas

El presente artículo analiza dos regímenes de pertenencia nacional explícitamente exclusivos e inclusivos, discutiendo dos casos de negociaciones actuales sobre extranjería y nacionalidad, en la r epública Dominicana y Venezuela. En Venezuela, a partir de la iniciativa gubernamental de 2004 en pos de una «regularización y naturalización de extranjeras/os», se les concedió la ciudadanía venezolana a inmigrantes indocumentados, algunos de ellos en el marco de grandes eventos públicos. En la r epública Dominicana, la exclusión administrativa de dominicanas/os de ascendencia haitiana se ha incrementado notablemente tras los cambios en la ley de inmigración en 2004, estableciendo que se considera como dominicano solo a los nacidos en el país, de padres o dominicanos o que viven de manera permanente dentro de la r epública Dominicana. En ambos casos queda evidente que las nociones de pertenencia son decisivas tanto para las políticas de inmigración como para las de nacionalidad; y que los dos ámbitos políticos mantienen una estrecha relación

Emergency Head & Spine Cases: Radiography, CT or MRI?

Introduction Emergency head and spinal patients are commonly seen in small animal practices. Radiography is widely available in small animal practice but has severe limitations for the head and spine. CT is available in most referral centers whereas MRI is limited to referral centers with a neurology focus. This presentation will focus on what can be diagnosed radiographically and if a referral is required, whether CT or MRI is more appropriate. This presentation will discuss different scenarios considering the strength and weaknesses of all modalities

Computed Tomography for the Emergency Thorax Patient

IntroductionComputed tomography (CT) is gaining popularity in the diagnostic work-up of emergency small animal patients with the newer generation of multi-slice computed tomography scanners. With these scanners it is possible to obtain thin slice images of an entire body region within 30 seconds or less. Use of contrast medium is essential for these to demonstrate vascular detail, parenchymal abnormalities, urinary and biliary excretion patterns.<br/

Radiography for the Acute Abdomen Patient

IntroductionRadiography has been the mainstay of the diagnostic imaging work up of canine and feline patients with acute abdominal signs for many years and continues to be an important triaging tool in the emergency patient due to its wide availability, low cost and quick performance qualities. <br/

Radiography for the Emergency Thorax Patient

IntroductionRadiography has been the mainstay in the diagnostic work up of dogs and cats with dyspnoea and other signs of respiratory disease. It is a quick, non-invasive diagnostic tool to screen the entire airways and lungs at a low cost. These criteria ensure that radiography will probably remain our first line diagnostic imaging tool for patients with respiratory disease for many years to come. <br/

Canine &amp; Feline Thoracic &amp; Musculoskeletal Radiology

In this one-day radiology course professor Tobias Schwarz will demonstrate techniques and tips for reading x-rays of thoracic and musculoskeletal system. There will be also an extensive practical part with cases to be discussed with the audience. By the end of this course all participants will be able to diagnose radiographically the most common thoracic and musculoskeletal diseases of dogs and cats.
