Análise das práticas e dos comportamentos de liderança dos alunos da Universidade da Madeira

Esta investigação, de carácter quantitativo, pretende descrever e analisar as práticas e os comportamentos de liderança dos alunos da Universidade da Madeira. Na recolha de dados foi utilizado o Student Leadership Practices Inventory (SLPI), um instrumento de 30 itens, desenvolvido por Kouzes e Posner (2006b), que avalia as práticas de liderança em cinco domínios. O questionário foi administrado por correio electrónico, durante o mês de Fevereiro de 2009, a uma amostra aleatória que incluiu 208 indivíduos. Os dados recolhidos foram tratados e analisados com recurso ao software estatístico SPSS 16.0 (Statistical Package for Social Sciences). A análise dos resultados indica que a prática de liderança utilizada pelo maior número de alunos da Universidade da Madeira é “habilitar a agir”. Verificou-se, ainda, que existem diferenças significativas entre os sexos nesta mesma prática de liderança, sendo os alunos do sexo feminino os que utilizam com maior frequência esta prática de liderança. Por outro lado, provou-se não existirem diferenças significativas na frequência de utilização das práticas “modelar caminho”, “inspirar uma visão partilhada”, “desafiar o processo” e “encorajar a vontade” quanto à idade, quanto ao exercício de uma actividade profissional e em relação ao facto do aluno estar ou não relacionado com uma organização.

Knowledge of the patients regarding leprosy and adherence to treatment

Leprosy is a chronic infectious disease caused by Mycobacterium leprae. It is known for its great disfiguring capacity and is considered an extremely serious disease to public health worldwide. The state of Ceará ranks 13th in number of cases of leprosy in Brazil, and fourth in Northeastern region, with an average of 2,149 new cases diagnosed every year. This study aimed to evaluate the knowledge of leprosy patients regarding treatment, and to assess the level of treatment adherence and its possible barriers. The study was conducted in the reference center for dermatology, from September 2010 to October 2010, in Fortaleza, Ceará. The study data were collected by means of a structured interview, along with the Morisky-Green test, in order to assess treatment adherence and barriers to adherence. A total of 70 patients were interviewed, out of whom 66 were new cases. The majority of patients were between 42 and 50 years old, and 37 (52.9%) were male. Most patients were clinically classified as presentingmultibacillary leprosy (80%), and 78.6% of them were from Fortaleza, Brazil. The Morisky-Green test indicated that 62.9% of patients presented a low level of adherence (p < 0.005), despite claiming to aware of the disease risks. However, it was observed that 57.1% of the patients had no difficulty adhering to treatment, while 38.6% reported little difficulty. This study shows that despite the patients claiming to be familiar with leprosy and its treatment, the Morisky-Green test clearly demonstrated that they actually were not aware of the principles of therapy, which is evidenced by the low degree of treatment adherence

A (anti)pedagogia da nota na escola

Esta investigación se propone a hacer un estudio acerca de la (anti)pedagogía de la nota como práctica escolar, a partir de la inclusión de los exámenes en lo cotidiano de la escuela de la Edad Media hasta la contemporaneidad, presentando los diversos cambios que sufrió a lo largo de ese período. Los objetivos de la investigación son: investigar, dentro de un contexto escolar definido, las representaciones en torno de la nota; analizar los factores que contribuyen para la construcción de una cultura escolar cuya preocupación primera es la nota; y revelar la ocurrencia de este hecho em un colegio público de enseñanza del Bachillerato en la ciudad de Natal. En relación a los procedimentos metodológicos, privelegiamos el estudio de caso, por ser más pertinente para aprehender la (anti)pedagogía de la nota en el colegio. Entendemos que, por medio de este procedimiento, se torna posible retratar la realidad escolar, desvelando acciones y prácticas pedagógicas que continúan centradas en la figura del profesor. El corpus empíricos de la investigación es constituido por datos recolectados en un colegio público del Bachillerato, a partir de observaciones en la sala de clase y conversaciones abiertas con los profesores y alumnos. El trabajo presenta también la apreciación de un estudio de caso, en el cual ocurre propriamente el desarrollo de la problemática en cuestión. Los análisis realizados utilizan categorías abstraídas de la lectura y/o estudio del material recolectado y las representaciones que circulan en el discurso de los profesores y alumnos

Avaliação dos indicadores de desempenho de instituições federais de educação tecnológica doBrasil na abordagem do balanced scorecard

This Master of Science Thesis deals with a study on applying the BSC Balanced Scorecard to assess the performance of Federal Institution for Technological Education Institution in Brazil, a government organizations non for profit. It s accomplished a literature review in order to understand the BSC and its application to non for profit organizations and as a main result it is proposed a BSC conceptual model with an inversion of the main BSC perspective from financial to customer/society. It is used the annual management report of thirteen Institutions and applied a Pearson correlation analysis in order to verify a cause-effect situation between indicators. The main findings suggest that the model teachers qualification in terms of degree earned, quantity of teachers in full time job, and rate of students by teacher in full time job having good pearson correlation with the results expected of quality, throughput, social and demand response. However, the student unit cost use as the sole financial indicator did not get any reasonable correlation with the results, as so the quality and quantity of books in the libraries. Although it suggests a need for improvement in the model, the general model adopted appears to be satisfactory as a starting point to a BSC-like performance measuring system to this kind of Institutions

Cuidado de si e hermenêutica do sujeito em Michael Foucault

The work, here present, has as its objective to present in a clear and distinct manner the object of study of Michel Foucault in his last years of teaching at the College de France, namely, the care of the self. We present the care of the self in its birth, in its origin, from the character Socrates and its development until the beginning of the Christian age. With a keen eye, we present Foucault with a work of return and rescue of the care of the self to the personal and academic discussions; we propose, from the self care, to the contemporary subject a problematization of their life so that from this questioning he creates for herself ways of life that are coherence, knowledge and care with which he has of must particular, his himself. Passing by the sources that served as the source of study for Foucault to sketch the birth of care of the self, we design the form with which Foucault has dealt with the documents that speak of the care of self. We present Socrates as one who by excellence ensures that the other will give birth to the forms of knowledge and care of the self or, in other words, we present the care of the self socratic-foucauldian as a constant worry of the other to pay attention to ways in which he conducts her life, it creates for themselves ways of being and, therefore, creates ethics of existence. We present, finally, the care of the self as the cause of continuous immanence of modes of subjectivation of the subject that configure themselves in a non-accepting a determined essence, but a continually updated form . The care of the self leads to a single relationship and educator of modes of subjectivation of the subject; he creates, on the dynamics of temporality, ethical ways of living, which are sustained by an internal coherence of the subject with herself; he admits no stationary nature in the training of the subject, always wants a more beautiful work of himself; he is not isolation, he needs and is made with the other. The care of the self is the principle and the telos of battles and conquests of the subject within his temporality and existence

Encoding mechanisms based on fast oscillations in the retina of the cat and their dependencies on anesthesia

Processing in the visual system starts in the retina. Its complex network of cells with different properties enables for parallel encoding and transmission of visual information to the lateral geniculate nucleus (LGN) and to the cortex. In the retina, it has been shown that responses are often accompanied by fast synchronous oscillations (30 - 90 Hz) in a stimulus-dependent manner. Studies in the frog, rabbit, cat and monkey, have shown strong oscillatory responses to large stimuli which probably encode global stimulus properties, such as size and continuity (Neuenschwander and Singer, 1996; Ishikane et al., 2005). Moreover, simultaneous recordings from different levels in the visual system have demonstrated that the oscillatory patterning of retinal ganglion cell responses are transmitted to the cortex via the LGN (Castelo-Branco et al., 1998). Overall these results suggest that feedforward synchronous oscillations contribute to visual encoding. In the present study on the LGN of the anesthetized cat, we further investigate the role of retinal oscillations in visual processing by applying complex stimuli, such as natural visual scenes, light spots of varying size and contrast, and flickering checkerboards. This is a necessary step for understanding encoding mechanisms in more naturalistic conditions, as currently most data on retinal oscillations have been limited to simple, flashed and stationary stimuli. Correlation analysis of spiking responses confirmed previous results showing that oscillatory responses in the retina (observed here from the LGN responses) largely depend on the size and stationarity of the stimulus. For natural scenes (gray-level and binary movies) oscillations appeared only for brief moments probably when receptive fields were dominated by large continuous, flat-contrast surfaces. Moreover, oscillatory responses to a circle stimulus could be broken with an annular mask indicating that synchronization arises from relatively local interactions among populations of activated cells in the retina. A surprising finding in this study was that retinal oscillations are highly dependent on halothane anesthesia levels. In the absence of halothane, oscillatory activity vanished independent of the characteristics of the stimuli. The same results were obtained for isoflurane, which has similar pharmacological properties. These new and unexpected findings question whether feedfoward oscillations in the early visual system are simply due to an imbalance between excitation and inhibition in the retinal networks generated by the halogenated anesthetics. Further studies in awake behaving animals are necessary to extend these conclusions

Fatores que influenciam a cooperação em humanos

Human cooperation is fundamentally affected by reciprocal exchange, but it is also remarkably common on the context of large and symbolically marked in-groups, which promote cooperation through the feeling of belonging to a group. In this thesis, two empirical articles were produced in order to investigate how human cooperation is affected by factors such as reciprocity, in-group behavior, in-group markers and gender. We investigated this subject through the administration of online games consisting of token donations, on which the subjects faced virtual players controlled by the experiment. We found that cooperative behavior is strongly influenced by reciprocity, and it is also affected by the in-group behavior, observed on the context of the social variables place of birth, ethnicity, and religions, once all of them acted as in-group markers. The subjects´ in-group behavior was enhanced when they played with generous in-group opponents, but weakened when their in-group opponents were non-generous. It was also found that cooperation is not affected by gender, but men and women cooperated in different ways under the influence of reciprocity and in-group behavior. Women are much more reciprocal on their cooperative behavior and men are less willing to cooperate with outgroupers, even when they act generously. The overall results contribute to a better understanding of the adaptive value of cooperation, reciprocity and in-group behavior on the solution of important challenges through the human evolutionary history

Uma abordagem sistemática para implementação, gerenciamento e customização de testes de linhas de produto de software

Through the adoption of the software product line (SPL) approach, several benefits are achieved when compared to the conventional development processes that are based on creating a single software system at a time. The process of developing a SPL differs from traditional software construction, since it has two essential phases: the domain engineering - when common and variables elements of the SPL are defined and implemented; and the application engineering - when one or more applications (specific products) are derived from the reuse of artifacts created in the domain engineering. The test activity is also fundamental and aims to detect defects in the artifacts produced in SPL development. However, the characteristics of an SPL bring new challenges to this activity that must be considered. Several approaches have been recently proposed for the testing process of product lines, but they have been shown limited and have only provided general guidelines. In addition, there is also a lack of tools to support the variability management and customization of automated case tests for SPLs. In this context, this dissertation has the goal of proposing a systematic approach to software product line testing. The approach offers: (i) automated SPL test strategies to be applied in the domain and application engineering, (ii) explicit guidelines to support the implementation and reuse of automated test cases at the unit, integration and system levels in domain and application engineering; and (iii) tooling support for automating the variability management and customization of test cases. The approach is evaluated through its application in a software product line for web systems. The results of this work have shown that the proposed approach can help the developers to deal with the challenges imposed by the characteristics of SPLs during the testing process

Dos requisitos à arquitetura em linhas de produtos de software: uma estratégia de transformações entre modelos

The tracking between models of the requirements and architecture activities is a strategy that aims to prevent loss of information, reducing the gap between these two initial activities of the software life cycle. In the context of Software Product Lines (SPL), it is important to have this support, which allows the correspondence between this two activities, with management of variability. In order to address this issue, this paper presents a process of bidirectional mapping, defining transformation rules between elements of a goaloriented requirements model (described in PL-AOVgraph) and elements of an architectural description (defined in PL-AspectualACME). These mapping rules are evaluated using a case study: the GingaForAll LPS. To automate this transformation, we developed the MaRiPLA tool (Mapping Requirements to Product Line Architecture), through MDD techniques (Modeldriven Development), including Atlas Transformation Language (ATL) with specification of Ecore metamodels jointly with Xtext , a DSL definition framework, and Acceleo, a code generation tool, in Eclipse environment. Finally, the generated models are evaluated based on quality attributes such as variability, derivability, reusability, correctness, traceability, completeness, evolvability and maintainability, extracted from the CAFÉ Quality Model

Reqsys-MDD: uma ferramenta para mapeamento entre modelos de features e requisitos em linhas de produto de software

The approach Software Product Line (SPL) has become very promising these days, since it allows the production of customized systems on large scale through product families. For the modeling of these families the Features Model is being widely used, however, it is a model that has low level of detail and not may be sufficient to guide the development team of LPS. Thus, it is recommended add the Features Model to other models representing the system from other perspectives. The goals model PL-AOVgraph can assume this role complementary to the Features Model, since it has a to context oriented language of LPS's, which allows the requirements modeling in detail and identification of crosscutting concerns that may arise as result of variability. In order to insert PL-AOVgraph in development of LPS's, this paper proposes a bi-directional mapping between PL-AOVgraph and Features Model, which will be automated by tool ReqSys-MDD. This tool uses the approach of Model-Driven Development (MDD), which allows the construction of systems from high level models through successive transformations. This enables the integration of ReqSys-MDD with other tools MDD that use their output models as input to other transformations. So it is possible keep consistency among the models involved, avoiding loss of informations on transitions between stages of development

Sistema de apoio à interatividade em revisões sistemáticas em engenharia de software

A colaboração na pesquisa é uma das tarefas centrais da área acadêmica. Atualmente, muitos pesquisadores estão utilizando meios modernos de troca de arquivos digitais através de ferramentas assíncronas e também com o uso de ferramentas mais sofisticadas, do tipo síncronas. Juntamente com o fato da crescente quantidade de artigos sendo gerados, mais complexos, diversificados e aumentando de forma desorganizada, o que trás ao pesquisador uma tarefa difícil para organizá-los de forma a se extrair o melhor conteúdo destes, isto ocorre porque uma subárea da Engenharia de Software (ES) ainda é bastante mal aproveitada, a Engenharia de Software Experimental (ESE). Utilizando-se de um dos tipos de experimentos que a ESE oferece, as revisões sistemáticas entram como uma solução bastante robusta, na qual o pesquisador pode identificar o conhecimento existente em uma área e planejar devidamente sua pesquisa, evitando a repetição de erros em pesquisas já efetivadas por outros pesquisadores no passado. Contudo, estas duas abordagens, a colaboração virtual de pesquisadores e a utilização de revisões sistemáticas, contem problemas: na primeira, sistemas colaborativos são geralmente difíceis de configurar e usar; na segunda, apesar da robustez da metodologia de revisões sistemáticas, ainda se torna necessário uma rigorosa revisão na literatura para se conseguir um resultado satisfatório. Assim, com o foco de unir estas duas abordagens, este trabalho propõe uma maneira de produzir revisões sistemáticas de forma organizada e com a possibilidade de interação entre usuários, com o desenvolvimento de um sistema interativo, no qual as revisões sistemáticas possam ser geradas por usuários em colaboração com outros e também ser avaliadas seguindo a orientação de um profissional da área, tornando o seu conteúdo mais consistente e de melhor qualidade. O sistema não possui níveis de acesso, ou seja, qualquer pessoa pode se cadastrar e usufruir de seus recursos, seja na área acadêmica ou mesmo na área profissional

Paracoccidioidomycosis: an unusual presentation in a young girl disclosing an unnoted HIV-infection

The association of paracoccidioidomycosis with AIDS is apparently less frequent than expected. The authors present an unusual case of paracoccidioidomycosis in a 13-year-old female student which was later found to be the first opportunistic infection in the course of the patient's HIV-infection. The clinical presentation followed an accidental incised wound on the palmar region initially described as a 'sporotrichotic-chancre'. After good response under sulfamethoxazole-trimethoprin, the patient relapsed and presented an associated oral candidiasis. HIV-infection was documented and additional investigation showed CD4(+) T-cells=22/mm(3), CD8(+)=280 cell/mm(3) and viral load=4,043 log. This case report presents an uncommon dermatological-clinical picture in the youngest patient in which such association has been reported to date.
