Los efectos de las variables micro ambiente hacia las conductas de los estudiantes de programas o cursos de inglés en la ciudad de Santa Marta
En este trabajo de grado se da a conocer las preferencias de los consumidores a la hora de elegir un programa de inglĂ©s personalizado en la ciudad de santa marta. El proceso de la enseñanza de inglĂ©s en la ciudad de santa marta se encuentra en 4 centros de este sector empresarial. De los cuales se busca cualificar la aceptaciĂłn de las personas hacia los programas de inglĂ©s personalizados con el fin de conocer la eficiencia y la eficacia de los centros de aprendizaje de inglĂ©s de santa marta como lo son El colombo, Obm, Ilc, Universidad del norte. Hoy en dĂa la mayorĂa de los egresados de la universidades no son bilingĂĽes en este caso el inglĂ©s, donde en está globalizaciĂłn hablar inglĂ©s es transcendental, muy pocos profesionales dominan y perfeccionan el inglĂ©s lo cual causa la perdida de negocios, proyectos con empresas internacionales, además se cree que el Ăşnico que debe hablar en inglĂ©s en una empresa es el gerente y la encargada de comercio exterior lo cual hace a la empresa muy dependiente de lo q puedan hacer estas dos profesionales en este campo, por esto es indispensable que todos los empleados tengan nociones sobre el idioma ingles y lo manejen de manera adecuada. La ciudades turĂsticas son un eje de llegada de extranjeros que en su mayorĂa no hablan el idioma español, su Ăşnico lengua es en el idioma inglĂ©s, al momento de habitar la ciudad turĂstica de santa marta quedan incomunicados con los ciudadanos que no hablan inglĂ©s, en este sentido ni los turistas hablan español y ni los samarios hablan el inglĂ©s, no hay forma de comunicarse entre el turista y el ciudadano de la ciudad de santa marta, por esto se pierden oportunidades de que los mismos turistas se queden en la ciudad mucho más tiempo y lo que pasa es que por el contrario duran un tiempo máximo de 1 mes por falta de comunicaciĂłn. Por Ăşltimo, es importante decir que Hoy en dĂa, en el competitivo mercado de trabajo, hablar inglĂ©s no es una opciĂłn, es una necesidad; Por algo se dice que el inglĂ©s es el idioma de los negocios. Si usted aprende inglĂ©s, tendrá una mejor oportunidad de conseguir un empleo mejor pagado o con un puesto más elevado, por esto, para todas las personas es fundamental aprender el idioma inglĂ©s ya que se habla de un profesional integro
Monte Carlo of Trapped Ultracold Neutrons in the UCNĎ„ Trap
In the UCNτ experiment, ultracold neutrons (UCN) are confined by magnetic fields and the Earth’s gravitational field. Field-trapping mitigates the problem of UCN loss on material surfaces, which caused the largest correction in prior neutron experiments using material bottles. However, the neutron dynamics in field traps differ qualitatively from those in material bottles. In the latter case, neutrons bounce off material surfaces with significant diffusivity and the population quickly reaches a static spatial distribution with a density gradient induced by the gravitational potential. In contrast, the field-confined UCN—whose dynamics can be described by Hamiltonian mechanics—do not exhibit the stochastic behaviors typical of an ideal gas model as observed in material bottles. In this report, we will describe our efforts to simulate UCN trapping in the UCNτ magneto-gravitational trap. We compare the simulation output to the experimental results to determine the parameters of the neutron detector and the input neutron distribution. The tuned model is then used to understand the phase space evolution of neutrons observed in the UCNτ experiment. We will discuss the implications of chaotic dynamics on controlling the systematic effects, such as spectral cleaning and microphonic heating, for a successful UCN lifetime experiment to reach a 0.01% level of precision
Socializing One Health: an innovative strategy to investigate social and behavioral risks of emerging viral threats
In an effort to strengthen global capacity to prevent, detect, and control infectious diseases in animals and people, the United States Agency for International Development’s (USAID) Emerging Pandemic Threats (EPT) PREDICT project funded development of regional, national, and local One Health capacities for early disease detection, rapid response, disease control, and risk reduction. From the outset, the EPT approach was inclusive of social science research methods designed to understand the contexts and behaviors of communities living and working at human-animal-environment interfaces considered high-risk for virus emergence. Using qualitative and quantitative approaches, PREDICT behavioral research aimed to identify and assess a range of socio-cultural behaviors that could be influential in zoonotic disease emergence, amplification, and transmission. This broad approach to behavioral risk characterization enabled us to identify and characterize human activities that could be linked to the transmission dynamics of new and emerging viruses. This paper provides a discussion of implementation of a social science approach within a zoonotic surveillance framework. We conducted in-depth ethnographic interviews and focus groups to better understand the individual- and community-level knowledge, attitudes, and practices that potentially put participants at risk for zoonotic disease transmission from the animals they live and work with, across 6 interface domains. When we asked highly-exposed individuals (ie. bushmeat hunters, wildlife or guano farmers) about the risk they perceived in their occupational activities, most did not perceive it to be risky, whether because it was normalized by years (or generations) of doing such an activity, or due to lack of information about potential risks. Integrating the social sciences allows investigations of the specific human activities that are hypothesized to drive disease emergence, amplification, and transmission, in order to better substantiate behavioral disease drivers, along with the social dimensions of infection and transmission dynamics. Understanding these dynamics is critical to achieving health security--the protection from threats to health-- which requires investments in both collective and individual health security. Involving behavioral sciences into zoonotic disease surveillance allowed us to push toward fuller community integration and engagement and toward dialogue and implementation of recommendations for disease prevention and improved health security

Grazing incidence neutron scattering for the study of solid–liquid interfaces
Neutrons are characterized by a low absorption in many engineering materials. At the same time the scattering cross section of light elements, such as hydrogen and deuterium, may be large. These properties make neutron scattering experiments performed under grazing incidence geometry an excellent tool for the study of solid–liquid interfaces. In this review we describe the basic concepts of neutron reflection and grazing incidence scattering experiments as well as experimental procedures and sample cells. The full power of the method is exemplified on a range of science areas, including polymers, bio- and ionic liquid lubricants, electrolytes as well as bio-membranes or magnetic liquids
