Professional masters were created in Brazil in the 1990s in response to social changes in the world of work and aim to train high-level professionals with own profile for various activities of society and the productive sector. They are up in more innovative mode of graduate studies in Brazil, and therefore lack of legitimacy of their identity, which raises the need for discussions to get further information and outline the characteristics of this postgraduate modality. You want to build new understandings about their peculiarities starting from the perspective of students from the Professional Masters in Health Net Northeast Family Training in Family Health, and not only according to the similarities and differences with the academic master. This study aims to understand the meanings attributed by masters training in that course. This is a qualitative, exploratory study. The subjects are 100 students in training in 2013, distributed among the six institutions nucleation Network Northeast Training in Family Health. To collect information desk research was conducted in institutional records of all students, as well as interviews. We interviewed 15 students, distributed in the six nucleation institutions. Information obtained through recorded interviews were transcribed and resulted in two analytical corpus subsequently submitted to Alceste © 4.9 software for identification of semantic classes. It can be concluded that the course provided a redefinition of professional practices in the Family Health Strategy, considering the organizational context of primary care in the Northeast and the specifics of the health work. Even before the student body difficulties related to ownership of research methods, and the very active methodology of problem-based learning, the course effectively contributed to the improvement of work processes in primary care, valuing teamwork and allowing the acquisition of new scientific knowledge.

This research deals with anorexia nervosa through the look of those who lived this experience. Eating Disorders have been presented as psychopathology increasingly recurrent in contemporary, being almost doubled incidence in the last 20 years, reaching mainly teenagers and bringing consequences and implications of various kinds. The literature points to the relevance of the current ideal of beauty, in which thinness is overvalued. In this case, the study’s objective was to understand, from an existential-phenomenological perspective, anorexia experience. Thus, when assessing the experience, seeking to understand the possible directions that the non-eating is for the person who lives such an experience. The study, of Heidegger's existential-phenomenological inspiration, used semi-structured interviews as a means of access to the experience. Female two people were interviewed, at the age of 17 and 30, began with a starter question ("How was, or how is, your anorexia experience?"), which allowed the interviewee to talk about their experience. For the selection of the study participant was publicized among health professionals, as well as in social networks and blogs, in which the research objectives and approaches have been made explicit. The field diary was also used as a methodological resource, seeking a greater approximation of the experiences of the interviewees and the researcher. The interviews were interpreted in the by Heidegger's hermeneutics. The meanings unveiled in the narratives revealed issues beyond the physical and pathological issue, being involved family, wishes, friends, experiences, life projects. The corporal, as thought by Martin Heidegger, became very present in the statements of the interviewees, as it is part of existence. Among the Heidegger´s ideas, emphasizes care, inhospitality, live, boredom, openness to possibilities and factuality, that might be discussed from interviewees' discourse, engendering reflections about their senses, in their lives.

This thesis proposes to trace and explore an emotional geography and cartography of the republican withdrawal at the end of the Spanish Civil War in Catalonia during the months of January and February 1939. Thus, it complements existing historiographical scholarship on the Spanish Civil War and Spanish Republican Exile, especially with regard to what was experienced in Catalan territory. However, its main purpose is not that of the historian, to reveal and explain unexplored stories, but to locate existing narratives, memoirs, journals and testimonies carefully in the landscape in which they took place, exposing their emotional bonds with the places and spaces of the withdrawal of the protagonists of the Republican exodus of 1939. Whilst there has been significant work in recent years to “recover” spaces associated with violent of traumatic memories of conflict and displacement, including the creation of a network of “Democratic Memory” places in Catalonia, the spaces explored in this thesis have not so far been construed as places of memory. In part, this is because of the diversity of emotions and affective responses they provoked and continue to evoke, but also because the geography of the Retirada is characterized by mobility and multiplicity. So instead of an historical approach, despite being influenced by Walter Benjamin's concept of history, this thesis draws on existing methods and approaches related to cultural geography, in particular, the emerging interdisciplinary field known as emotional geographies. In order to create a vision of La Retirada that is sensitive to its mobility and multiplicity, the primary methodology used has been that of interdisciplinary assemblage, juxtaposing images, documents and stories of past and present, in a process redolent of that which Marianne Hirsch calls "post-memory".

With the expansion and increased availability of Higher Education the progression to study for an undergraduate degree has been viewed as a simple stepping stone with examination success a straight - forward border pass. Changes in the funding of degree courses has established a series of more challenging boundaries to entry which demand a rigorous assessment of the benefits of Higher Education. The Widening Participation Unit at The University of Worcester has sought to ease this border crossing for pupils whose parents have not been to university. Their experience from previous projects was that school pupils more easily relate to undergraduate students whose experience of Higher Education is recent and relevant. With this in mind they commissioned the Drama and Performance Department to create a Theatre in Education programme that introduced an awareness of post sixteen options and future choices to challenge Higher Education stereotypes. As a result of this collaboration Why Bother? was created, directed by myself and devised and researched with four students who were studying drama. Their own experiences were used to inform the character development and dealt with worrying as a mature student about integration into full – time education, loss of income after working, the pressures of emotional commitments to partners and being away from home. The programme toured to two thousand year 9 – 11 pupils in Worcestershire and Herefordshire schools in January and May 2011. Devising and touring Why Bother provided students with an opportunity to work as a professional paid TIE team that it is not possible for them to do as part of their undergraduate degree course. My initial research looks at the effectiveness and limitations of this project based on pupil questionnaires and the experiences of the team which are explored within the broader context of TIE and its potential for affecting attitudinal change. This has given rise to a number of questions that need consideration in the development of a new TIE programme aimed at raising the awareness of sixth form students who are about to make the decision whether to apply to university or not. Collaboration with university students in exploring the value of an education that they have subscribed to raises issues of bias and whether their powers of persuasion actually prevent pupils from making their own individual decision. The ethics of promoting a “free” university education seem much less complex than the decision required now which involves balancing the real value against the high financial cost suggested in the working title of Is it Worth it? This paper will present my first attempts to develop research methods and methodologies that will enable me to evaluate the success of this and future TIE.

Kandidaatintyön tarkoituksena oli selvittää pienahitsin juuren kriittisyyttä. Työ oli saanut aiheen rakenneputki kokeiden yhteydessä tehdyistä havainnoista. Työssä tutustuttiin millaiset ovat pienahitsin mitoitus menetelmät ja tausta tutkimusta kuinka sitä sovelletaan käytäntöön suurlujuusteräksille. Työssä esitellään käytetyt tutkimusmenetelmät kuinka menetelmätriangulaatio saavutettiin. Tutkimuskysymyksenä oli hitsien kestävyyden mitoituksen riittävyys. Tutkimukset suoritettiin tarkastellen staattisesti kuormitettuja pienahitsejä. Pienahitsi kappaleista tehtiin laboratoriokoekappale ja FEM-laskentamalli joista vertailtiin tuloksia. Laboratoriokokeessa mittaus menetelmänä käytettiin DIC-mittausta, jolle voitiin tehdä jälkikäsittelyjä ja sieltä määrittää haluttuja datapisteitä. Laskennassa suurimmat jännityskeskittymät syntyivät hitsin kohdalle mutta vetokokeessa koekappaleeseen syntyi vauriot sularajalle ja vetokorvakkeen kiinnityshitsin rajaviivalle. Tällä kohtaa todettiin materiaalimalli riittämättömäksi, koska siihen ei ollut määritelty muutosvyöhykkeen parametreja.

The Moreton Bay prawn trawl fishery is one of Queensland’s oldest commercial fisheries, but is currently economically unsustainable. The fishery is characterized by a mix of large and small vessels, with the small vessels facing different licensing and boat replacement restrictions to the large. Industry have proposed the removal of the current two-for-one boat replacement policy that affects the smaller vessels to encourage investment and replacement by larger vessels, although there is concern by managers about the impact of this on total fishing effort and sustainability of the stocks, despite the existence of a total cap in vessel capacity units. We estimate the impact of removing the boat replacement policy for the smaller vessels on fleet performance and total fishing effort, and find that removing the boat replacement policy is unlikely to result in a substantial increase in fishing effort due to the existence of a vessel unitization scheme.

La nanotecnología es un área de investigación de reciente creación que trata con la manipulación y el control de la materia con dimensiones comprendidas entre 1 y 100 nanómetros. A escala nanométrica, los materiales exhiben fenómenos físicos, químicos y biológicos singulares, muy distintos a los que manifiestan a escala convencional. En medicina, los compuestos miniaturizados a nanoescala y los materiales nanoestructurados ofrecen una mayor eficacia con respecto a las formulaciones químicas tradicionales, así como una mejora en la focalización del medicamento hacia la diana terapéutica, revelando así nuevas propiedades diagnósticas y terapéuticas. A su vez, la complejidad de la información a nivel nano es mucho mayor que en los niveles biológicos convencionales (desde el nivel de población hasta el nivel de célula) y, por tanto, cualquier flujo de trabajo en nanomedicina requiere, de forma inherente, estrategias de gestión de información avanzadas. Desafortunadamente, la informática biomédica todavía no ha proporcionado el marco de trabajo que permita lidiar con estos retos de la información a nivel nano, ni ha adaptado sus métodos y herramientas a este nuevo campo de investigación. En este contexto, la nueva área de la nanoinformática pretende detectar y establecer los vínculos existentes entre la medicina, la nanotecnología y la informática, fomentando así la aplicación de métodos computacionales para resolver las cuestiones y problemas que surgen con la información en la amplia intersección entre la biomedicina y la nanotecnología. Las observaciones expuestas previamente determinan el contexto de esta tesis doctoral, la cual se centra en analizar el dominio de la nanomedicina en profundidad, así como en el desarrollo de estrategias y herramientas para establecer correspondencias entre las distintas disciplinas, fuentes de datos, recursos computacionales y técnicas orientadas a la extracción de información y la minería de textos, con el objetivo final de hacer uso de los datos nanomédicos disponibles. El autor analiza, a través de casos reales, alguna de las tareas de investigación en nanomedicina que requieren o que pueden beneficiarse del uso de métodos y herramientas nanoinformáticas, ilustrando de esta forma los inconvenientes y limitaciones actuales de los enfoques de informática biomédica a la hora de tratar con datos pertenecientes al dominio nanomédico. Se discuten tres escenarios diferentes como ejemplos de actividades que los investigadores realizan mientras llevan a cabo su investigación, comparando los contextos biomédico y nanomédico: i) búsqueda en la Web de fuentes de datos y recursos computacionales que den soporte a su investigación; ii) búsqueda en la literatura científica de resultados experimentales y publicaciones relacionadas con su investigación; iii) búsqueda en registros de ensayos clínicos de resultados clínicos relacionados con su investigación. El desarrollo de estas actividades requiere el uso de herramientas y servicios informáticos, como exploradores Web, bases de datos de referencias bibliográficas indexando la literatura biomédica y registros online de ensayos clínicos, respectivamente. Para cada escenario, este documento proporciona un análisis detallado de los posibles obstáculos que pueden dificultar el desarrollo y el resultado de las diferentes tareas de investigación en cada uno de los dos campos citados (biomedicina y nanomedicina), poniendo especial énfasis en los retos existentes en la investigación nanomédica, campo en el que se han detectado las mayores dificultades. El autor ilustra cómo la aplicación de metodologías provenientes de la informática biomédica a estos escenarios resulta efectiva en el dominio biomédico, mientras que dichas metodologías presentan serias limitaciones cuando son aplicadas al contexto nanomédico. Para abordar dichas limitaciones, el autor propone un enfoque nanoinformático, original, diseñado específicamente para tratar con las características especiales que la información presenta a nivel nano. El enfoque consiste en un análisis en profundidad de la literatura científica y de los registros de ensayos clínicos disponibles para extraer información relevante sobre experimentos y resultados en nanomedicina —patrones textuales, vocabulario en común, descriptores de experimentos, parámetros de caracterización, etc.—, seguido del desarrollo de mecanismos para estructurar y analizar dicha información automáticamente. Este análisis concluye con la generación de un modelo de datos de referencia (gold standard) —un conjunto de datos de entrenamiento y de test anotados manualmente—, el cual ha sido aplicado a la clasificación de registros de ensayos clínicos, permitiendo distinguir automáticamente los estudios centrados en nanodrogas y nanodispositivos de aquellos enfocados a testear productos farmacéuticos tradicionales. El presente trabajo pretende proporcionar los métodos necesarios para organizar, depurar, filtrar y validar parte de los datos nanomédicos existentes en la actualidad a una escala adecuada para la toma de decisiones. Análisis similares para otras tareas de investigación en nanomedicina ayudarían a detectar qué recursos nanoinformáticos se requieren para cumplir los objetivos actuales en el área, así como a generar conjunto de datos de referencia, estructurados y densos en información, a partir de literatura y otros fuentes no estructuradas para poder aplicar nuevos algoritmos e inferir nueva información de valor para la investigación en nanomedicina. ABSTRACT Nanotechnology is a research area of recent development that deals with the manipulation and control of matter with dimensions ranging from 1 to 100 nanometers. At the nanoscale, materials exhibit singular physical, chemical and biological phenomena, very different from those manifested at the conventional scale. In medicine, nanosized compounds and nanostructured materials offer improved drug targeting and efficacy with respect to traditional formulations, and reveal novel diagnostic and therapeutic properties. Nevertheless, the complexity of information at the nano level is much higher than the complexity at the conventional biological levels (from populations to the cell). Thus, any nanomedical research workflow inherently demands advanced information management. Unfortunately, Biomedical Informatics (BMI) has not yet provided the necessary framework to deal with such information challenges, nor adapted its methods and tools to the new research field. In this context, the novel area of nanoinformatics aims to build new bridges between medicine, nanotechnology and informatics, allowing the application of computational methods to solve informational issues at the wide intersection between biomedicine and nanotechnology. The above observations determine the context of this doctoral dissertation, which is focused on analyzing the nanomedical domain in-depth, and developing nanoinformatics strategies and tools to map across disciplines, data sources, computational resources, and information extraction and text mining techniques, for leveraging available nanomedical data. The author analyzes, through real-life case studies, some research tasks in nanomedicine that would require or could benefit from the use of nanoinformatics methods and tools, illustrating present drawbacks and limitations of BMI approaches to deal with data belonging to the nanomedical domain. Three different scenarios, comparing both the biomedical and nanomedical contexts, are discussed as examples of activities that researchers would perform while conducting their research: i) searching over the Web for data sources and computational resources supporting their research; ii) searching the literature for experimental results and publications related to their research, and iii) searching clinical trial registries for clinical results related to their research. The development of these activities will depend on the use of informatics tools and services, such as web browsers, databases of citations and abstracts indexing the biomedical literature, and web-based clinical trial registries, respectively. For each scenario, this document provides a detailed analysis of the potential information barriers that could hamper the successful development of the different research tasks in both fields (biomedicine and nanomedicine), emphasizing the existing challenges for nanomedical research —where the major barriers have been found. The author illustrates how the application of BMI methodologies to these scenarios can be proven successful in the biomedical domain, whilst these methodologies present severe limitations when applied to the nanomedical context. To address such limitations, the author proposes an original nanoinformatics approach specifically designed to deal with the special characteristics of information at the nano level. This approach consists of an in-depth analysis of the scientific literature and available clinical trial registries to extract relevant information about experiments and results in nanomedicine —textual patterns, common vocabulary, experiment descriptors, characterization parameters, etc.—, followed by the development of mechanisms to automatically structure and analyze this information. This analysis resulted in the generation of a gold standard —a manually annotated training or reference set—, which was applied to the automatic classification of clinical trial summaries, distinguishing studies focused on nanodrugs and nanodevices from those aimed at testing traditional pharmaceuticals. The present work aims to provide the necessary methods for organizing, curating and validating existing nanomedical data on a scale suitable for decision-making. Similar analysis for different nanomedical research tasks would help to detect which nanoinformatics resources are required to meet current goals in the field, as well as to generate densely populated and machine-interpretable reference datasets from the literature and other unstructured sources for further testing novel algorithms and inferring new valuable information for nanomedicine.

The microfoundations research agenda presents an expanded theoretical perspective because it considers individuals, their characteristics, and their interactions as relevant variables to help us understand firm-level strategic issues. However, microfoundations empirical research faces unique challenges because processes take place at different levels of analysis and these multilevel processes must be considered simultaneously. We describe multilevel modeling and mixed methods as methodological approaches whose use will allow for theoretical advancements. We describe key issues regarding the use of these two types of methods and, more importantly, discuss pressing substantive questions and topics that can be addressed with each of these methodological approaches with the goal of making theoretical advancements regarding the microfoundations research agenda and strategic management studies in general.

Ticks are obligate haematophagous ectoparasites of wild and domestic animals as well as humans, considered to be second worldwide to mosquitoes as vectors of human diseases. Tick-borne diseases are responsible worldwide for great economic losses in terms of mortality and morbidity of livestock animals. This review concerns to the different tick and tick-parasites control methods having a major focus on vaccines. Control of tick infestations has been mainly based on the use of acaricides, a control measure with serious drawbacks, as responsible for the contamination of milk and meat products, as a selective factor for acaricide-resistant ticks and as an environmental contaminant. Research on alternatives to the use of acaricides is strongly represented by tick vaccines considered a more cost-effective and environmentally safe strategy. Vaccines based on the Bm86 tick antigen were used in the first commercially available cattle tick vaccines and showed good results in reducing tick numbers, affecting weight and reproductive performance of female ticks which resulted in reduction of cattle tick populations over time and consequently lower reduction of the pathogen agents they carry.

This paper describes new approaches to social and economic research being developed by the Social and Economic Research component of the Special Programme for Research and Trainning in Tropical Diseases of the World Health Organization. One of these is a study to acess the possibility of identifying high risk communities for urinary schistosomiasis through a "mailed"questionaire approach distributed through an existing administrative system, thereby eliminating the need for face-to-face interviews by the research or disease control team. This approach, developed by the Swiss Tropical Institute in Ifakara, Tanzania, i s currently being tested in seven other African countries. The paper also describes a change of emphasis of economic research on schistosomiasis, focusing on the intra-household effects of the disease on rural households, rather than, as previously done, studying the impact of the disease on the productivity of individual wage labourers. Other priorities involve the identification of epidemiological information neede for improoved decision-making regarding acceptable treatment strategies in endemic areas with limited financial capacity, as well as research on how the adverse effects of economic development projects can be alleviated.
