Stress und Belastung bei Personen im diplomatischen Dienst (Stress and burden in diplomatic service).

This paper describes working and living conditions of persons within diplomatic services from the perspective of stress and demands. The conditions of stress and demands described in this article are similar for leaders, volunteers, actors of international agencies and nongovernmental organizations. Scope and diversity of diplomatic tasks and connected psychsocial stress will be outlined. Families of diplomates are also affected. Mental health problems in the diplomatic corps are known, but they are considered as a taboo issue. Consequently, the basis of empirical research and literature is limited. It is mentioned that expatriates, migrants, refugees and students in foreign countries can develop similar problems. The role of psychology and psychotherapeutic interventions are discussed.

Design and characterization of Electrochemical Sensors for Organic Bioelectronics

This Ph.D. Thesis concerns the design and characterisation of functional electrochemical interfaces in organic electronic devices for bioelectronic applications. The Thesis is structured as follows: Chapter I – Technological context that has inspired the research, introduction to Organic Bioelectronics and literature review concerning Organic Electrochemical Transistors (OECTs) for sensing applications. Chapter II – Working principle of an all-polymeric OECT and operando microscopic characterization using scanning electrochemical techniques. Chapter III – Dopamine detection with all-polymeric OECT sensors. Development of a potentiodynamic approach to address selectivity issues in the presence of interfering species and design of a needle-type, sub-micrometric OECT sensor for spatially resolved detection of biological Dopamine concentrations. Chapter IV – Development of an OECT pH sensor. Characterization of the electrochemical transducer and functionalization of the OECT gate electrode with the sensing material. Potentiodynamic and potentiostatic operation modalities are explored and the sensing performances are assessed in both cases. The final device is realized on a flexible substrate and tested in Artificial Sweat. Chapter V – Study of two-terminal, electrochemically gated sensors inspired by the OECT configuration. Design and characterization of novel functional materials showing a potentiometric transduction of the chemical signal that can be exploited in the realization of electrochemical sensors with simplified geometry for wearable applications. Chapter VI – Conclusion.

Water and sediments geochemistry and elemental fluxes on a Large Dam: case study of Ridracoli reservoir.

Since the study of Large Dam Reservoirs is of worldwide interest, in this PhD project we investigated the Ridracoli reservoir, one of the main water supply in Emilia-Romagna (north-eastern Italy). This work aims to characterize waters and sediments to better understand their composition, interactions and any process that occurs, for a better geochemical and environmental knowledge of the area. Physical and chemical analyses on the water column have shown an alternation of stratification and mixing of water in the reservoir’s water body due to seasonal variations in temperature and density. In particular, it was observed the establishment, in late summer, of anoxic conditions at the bottom, which in turn affects the concentration and mobility of some elements of concern (e.g. Fe and Mn) for the water quality. Sediments within the reservoir and from surrounding areas were analysed for organic matter, total inorganic composition and grain size, assessing the inter-element relationship, grain size, geological background and damming influences on their chemistry, through descriptive statistics, Principal Component Analysis and Cluster Analysis. The reservoir’s area was also investigated by pseudo total composition (Aqua Regia digestion), degree of elements extractability, and enrichment factors, then analysed and compared to limits by law and literature. Sediment cores, interstitial waters, and benthic chamber data from the bottom were of great interest due to organic matter degradation, early diagenesis, mineral formation at water-sediment interface and observed flows. Finally, leaching test and extraction procedures, of environmental interest, showed peculiar partitioning, both regarding spatial and in-depth distribution, and the absence of pollution. Collectively, our results are useful for the comprehension of processes that occur in water and sediments of Ridracoli reservoir, providing important knowledges on the site that could be relevant for the management of the resource and the planning of future interventions.

Flaubert e o crepúsculo do sujeito: uma análise do conto "Um coração simples"

A literatura francesa e mundial passaram por uma enorme transformação ao longo do século XIX. A primorosa escrita de Flaubert é, para além de sua importância estética, reveladora de um novo modo de se escrever, ler e representar o homem no mundo moderno. O cuidado na construção do texto, a utilização de imagens plásticas e figuras de linguagem, ao mesmo tempo em que o narrador torna-se invisível no emprego do discurso indireto livre são característicos da escrita flaubertiana. O autor apresenta-nos em "Um coração simples" um "retrato" de Félicité, mulher pobre do interior da França, modelo virtuoso de uma ética evanescente. Ao acompanhar, por meio do conto, os passos e desventuras de Felicité, sob as lentes deste novo narrador, buscamos evidenciar as condições que circundam o aparecimento de um olhar científico-objetivo para a subjetividade humana, logo transformada em objeto de uma nascente Psicologia.

Prevalência de sintomas depressivos na perimenopausa

OBJETIVO: realizar revisão sistemática de estudos de prevalência dos sintomas depressivos na perimenopausa.MÉTODO: A pesquisa foi efetuada a partir das bases de dados MEDLINE e EMBASE. Foram incluídos estudos transversais originais com populações adultas (idade de 40 a 55 anos), no período de 1996 a 2006, que estimaram a prevalência de sintomas depressivos na perimenopausa nos idiomas: inglês, francês, espanhol e português. A seleção dos estudos pela estratégia de busca foi feita de forma independente por dois avaliadores. Foram incluídos os estudos que preencheram os seguintes critérios metodológicos: características epidemiológicas, definições de perimenopausa, instrumentos válidos utilizados para sintomas depressivos.RESULTADOS: Após a avaliação de 1.345 artigos, restaram apenas cinco que caracterizaram uma população de 11.020 mulheres com idades entre 40 e 60 anos. Constatamos que a prevalência de sintomas depressivos na perimenopausa variou entre 19% e 73%.CONCLUSÃO: A presente revisão sistemática mostrou expressiva variação na prevalência de sintomas depressivos na perimenopausa; ademais, não foi possível caracterizar se a sintomatologia depressiva na perimenopausa decorreu exclusivamente de flutuações hormonais observadas neste estágio da vida ou de antecedentes prévios de depressão

Towards a History didactics definition

This paper aims to define history didactics along the lines of the current German literature, which conceives it to be closer to history than to education. Associated to the word Geschichtsdidaktik, this definition is opposed to the concepts of history didactics as the art of teaching - Lehrkunst - history or as a collection of methods used both in the teaching of history and in the teaching of other school subjects - Unterrichtsmethoden. In opposition to these two definitions, this paper discusses German, French and Brazilian literatures to propose a conception of history didactics as a subarea of history, once it does not encompass only history teaching, but all history elaborations without a scientific form - nicht- wissenschaftsformigen Geschichtsverarbeitungen.
