Relations among several nuclear and electronic density functional reactivity indexes

A set of connections among several nuclear and electronic indexes of reactivity in the framework of the conceptual Density Functional Theory by using an expansion ofthe energy functional in terms of the total number of electrons and the normal coordinates within a canonical ensemble was derived. The relations obtained provided explicit links between important quantities related to the chemical reactivity of a system. This paper particularly demonstrates that the derivative of the electronic energy with respect to the external potential of a system in its equilibrium geometry was equal to the negative of the nuclear repulsion derivative with respect to the external potential

Applied psychology in International Relations

Em consequência da globalização e dos actuais conflitos mundiais, milhares de pessoas deixaram a sua pátria para viver durante alguns anos noutros países, frequentemente junto dos seus familiares. Alguns partem pela sua própria vontade, porque trabalham para o seu Governo, para as suas empresas ou para uma organização internacional, porque querem estudar no estrangeiro ou simplesmente porque procuram um emprego e uma vida melhor. Outros, normalmente num contexto violento, são forçados a partir e apenas procuram paz e apoio. Este artigo apresenta um panorama das contribuições da Psicologia para as relações internacionais (RI). Propõe cinco tipos de actores de RI: diplomatas(incluindo pessoal consular e administrativo), voluntários internacionais (ONG e participantes em missões de paz), expatriados (incluindo estudantes), migrantes (documentados e não documentados) e refugiados. Define as suas tarefas (e/ou necessidades) e os problemas inerentes, também para a família. Depois, trata as seguintes áreas de pesquisa que podem ajudar os actores a realizar as suas tarefas e resolver os seus problemas: análise de acontecimentos políticos, análise de conflitos; resolução e prevenção; negociação e mediação; tomada de decisão, análise da linguagem, análise de factores culturais,operações de peacekeeping & desenvolvimento da paz pós-conflito, saúde mental, e know- -how e gestão organizacional. É feita uma breve consideração sobre cada área, enfatizando assuntos práticos.

Using eye-tracking to study anaphoric relations processing in European Portuguese

In this study we evaluate processing costs of different types of anaphoric expressions during reading. We consider three types of anaphoric expressions in Subject sentential position: a null pronoun (pro), and two gaps produced by syntactic movement: a WHvariable and a NP copy. Given that coreferential pro exhibits more referential weight than wh- and NP-gaps, and grounded on theories of referential processing based on relations of hierarchy and accessibility of the antecedent, we raise the hypothesis that the more dependent on its antecedent the anaphoric null constituent is, and the more minimal is the distance in terms of hierarchical structure between the anaphoric null element and its antecedent, the lower are the cognitive costs in processing. To test our hypothesis, we registered the eye movements with R6-HS ASL system of 20 Portuguese adult native speakers. Text regions including the selected anaphoric expressions were delimited and tagged. We analyzed the reading time of each region taking into account the number and duration of eye fixations per region; we used the reading time by character in milliseconds in order to compare values between regions of different length. We found a significant advantage in the reading time of the gaps arising from movement over the reading time of pro.

The phase relations of normal ears compared with the phase relations of otosclerotic ears before and after the fenestration operation

This paper discusses the fenestration operation and its effect on hearing.

Integrating participatory community mobilization processes to improve dengue prevention: an eco-bio-social scaling up of local success in Machala, Ecuador

This project investigates the effectiveness and feasibility of scaling-up an eco-bio-social approach for implementing an integrated community-based approach for dengue prevention in comparison with existing insecticide-based and emerging biolarvicide-based programs in an endemic setting in Machala, Ecuador.
