Os contratos de autonomia na gestão dos agrupamentos de escola em Portugal: uma análise a partir da perceção dos atores

No final da década de 70 a reforma da Administração Pública surge como preocupação dos governos. No início dos anos 80 a adoção da doutrina da Nova Gestão Publica, foi um dos acontecimentos mais marcantes para a administração pública dos países da Organização para a Cooperação e Desenvolvimento Economico. A reforma na Administração Pública em Portugal iniciou-se após a rutura política e social de 1974. No início de 1986 Portugal entra para Comunidade Económica Europeia, o que representou uma maior abertura económica e um aumento na confiança interna da população, observando-se um avanço em termos de concretização de muitos direito sociais, entre outros, na educação. A modernização da administração pública na componente referente à área da educação, iniciou-se no final do ano de 1986, através da Lei de Base do Sistema Educativo, dando origem à descentralização dos serviços, introduzindo-se o conceito de autonomia. Os contratos de autonomia no meio escolar, são processos de administração que não influenciam os seus intervenientes, na realização das atividades pedagógicas, administrativas e gestionárias. Este estudo demonstra a opinião dos vários grupos que compõem um estabelecimento de ensino público Português. Na opinião da amostra deste estudo, os contratos de autonomia não são portadores de benefícios ou prejuízos para os estabelecimentos escolares, seja a nível pedagógico, a nível dos recursos humanos ou a nível administrativo e financeiro; Abstract: Contracts of autonomy in the management of grouping of schools in Portugal: An analysis based on the perception of the actors. At the end of the 70 the reform of public administration arises as a concern of governments. In the early 80s the adoption of the doctrine of the New Public Management, was one of the most important events for the public administration of the Organization for Cooperation and Economic Development countries. The reform in Public Administration in Portugal began after the political and social rupture of 1974. In the beginning of 1986 Portugal joins the European Economic Community, which represented a greater economic openness and an increase in internal confidence of the population, shown by a progress in terms of implementation of many social rights, among others, in education. The modernization of public administration in the field of education began at the end of 1986 through the Basic Law of Education, leading to the decentralization of services, introducing therefore the concept of autonomy. Autonomy contracts in schools are management processes that do not influence their stakeholders in achieving the educational, administrative and management activities. This study shows the opinion of the various groups that form an establishment of Portuguese public education. According to the sample, the autonomy contracts don’t bring benefits or losses to schools, as far as educational practices and human resources are concerned, as well as on a financial and administrative level.

Allergological evaluation of a dog population in a veterinary immuno-allergology consultation: What correlates in a canine model

Introduction: Allergic dermatitis (AD) is the most common canine pruritic condition in veterinary dermatology. Allergic dermatitis to flea bites presents the highest prevalence, followed by atopic dermatitis and food AD. This study aimed to identify possible correlation between data from clinical signs, intradermal tests (IDT) and specific IgE levels, which are used in dog AD assessment. Methods: Fifty five dogs from the Veterinary Hospital of the University of Évora (Portugal) and Rof Codina University Hospital (Lugo, Spain) outpatient consultations were studied by means of clinical inquiry, IDT and specific IgE determination. Thirty five of the patients belonged to predisposed breeds, 30 were females and 25 males. Forty one (74%) were indoor. Results: In 82% of cases first clinical signs appeared before the age of 3 years and 24% even before 1 year old. In 70% of the individuals clinical signs included itching, which was generalized in 66%, with 78% of paw licking and chewing. Clinical profile showed seasonal worsening in 64% of cases. From the 69.1% of dogs already presenting with dermatitis, 50% also presented external otitis and 28.9% self-inflicted alopecia. "Intense itching" was found in 10.5%, "medium itching" in 81.6% and “mild itching” in 5.26% of the patients. Prevalence of positive IDT was 37.3 % to Lep d, 29.41% to Der f, 27.5% to Der p, 25.5% to Dac g and 21.6% to Malassezia sp. From the 37 dogs submitted to food IDT, 40.5% revealed positive to beef, 27% to chicken, 27% to porc and 5.4% to lamb. Specific IgE > 150 EAU was found in 84% of dogs to indoor allergen sources and in 68% to pollens. A negative correlation was found between an outdoor life and the intensity (p = 0.033) and precocity (p = 0.026) of clinical signs. Sensitization to pollens was found positively correlated with the seasonality of clinical signs (p = 0.001) and the positivity for Dac g (p = 0.007). The prevalence of chronic otitis correlated positively with alopecia and reactivity to Lep d (p = 0.008), Plantago lanceolata (p = 0.026) and Platanus acerifolia (p = 0.017). There was no correlation between the results of ITD and specific IgE. Conclusion: We can conclude that correlation between different clinical signs and positive testing for some allergenic sources may occur, as well as between sensitization to pollens and the beginning, the intensity and the seasonality of dog patient clinical signs.

Expenditure pattern analysis of cultural tourists at World Heritage Sites: an empirical evidence based on CHAID analysis

Nowadays, World Heritage Sites (WHS) have been facing new challenges, partially due to a different tourism consumption patterns. As it is highlighted in a considerable amount of studies, visits to these sites are almost justified by this prestigious classification and motivations are closely associated with their cultural aspects and quality of the overall environment (among others, Marujo et al, 2012). However, a diversity of tourists’ profiles have been underlined in the literature. Starting from the results obtained in a previous study about cultural tourists’ profile, conducted during the year 2009 in the city of Évora, Portugal, it is our intend to compare the results with a recent survey applied to the visitors of the same city. Recognition of Évora by UNESCO in 1986 as “World Heritage” has fostered not only the preservation of heritage but also the tourist promotion of the town. This study compares and examined tourists’ profile, regarding from the tourists’ expenditure patterns in Évora. A total of 450 surveys were distributed in 2009, and recently, in 2015, the same numbers of surveys were collected. Chi-squared Automatic Interaction Detection (CHAID) was applied to model consumer patterns of domestic and international visitors, based on socio demographic, trip characteristics, length of stay and the degree of satisfaction of pull factors. CHAID allowed find a population classification in groups that able to describe the dependent variable, average daily tourist expenditure. Results revealed different patterns of daily average expenditure amongst the years, 2009 and 2015, even if primarily results not revealed significant variations in socio-demographic and trip characteristics among the visitors’ core profile. Local authorities should be aware of this changing expensive behavior of cultural visitors and should formulate strategies accordingly. Policy and managerial recommendations are discussed.

Generalities of vertebrate responses to landscape composition and configuration gradients in a highly heterogeneous Mediterranean region

Aim To examine the distributional patterns of vertebrates (including birds, bats, carnivores and lagomorphs) along landscape composition and configuration gradients to better understand the effects of landscape modification on occurrence patterns at both species and community level. Location The region of Alentejo, a forest-dominated area of southern Portugal. Methods The study area was framed using 1647 hexagonal plots, each of 259 ha in size. Composition and configuration gradients were obtained for each plot by integrating the proportions of the main land cover types and their configuration patterns using multivariate analyses. Species-specific vertebrate responses were investigated using data from 75 plots in which carnivores, bats and lagomorphs were sampled, and from 135 plots in the case of birds. Community- level responses were investigated through changes in species richness and beta-diversity in 57 plots where all vertebrate groups were simultaneously sampled. At the species-level, an information-theoretic approach was used to determine the effects of landscape gradients on species’ responses. At the community level, Mantel tests were used to determine between-plot differences in species composition using the Sørensen dissimilarity index. Results We found that the occurrence patterns of most vertebrate species were best predicted by composition-related gradients, although configuration gradients were also frequently included in species-specific occurrence models. We also found a weak correlation between species richness and most landscape gradients suggesting a turnover in the identity of species, something that was corroborated by the stronger correlation between environmental gradients and beta-diversity measures. The amount of forest cover and landscape complexity (estimated as the heterogeneity in the size and number of land cover types) were the main composition and configuration gradients determining vertebrate responses at both species and community level. Main conclusions Our work contributes to a more refined understanding of the mechanisms underlying species distributional patterns in real-world human-modified landscapes. By uncovering generalities of species with multiple ecological requirements and by describing the entire landscape mosaic through landscape gradients, we also suggest that our work greatly helps to fill the gap between existing conceptual landscape models aimed to understand species distributional patterns in human-modified landscapes.

A segunda vida da Praia dos Espanhóis: dançarinos, pescadores e turistas no sul de Portugal

Abstract: In this text, we deal with proccesses of appropriation of space in the Dam of Póvoa (Portugal) using a dwelling perspective (Ingold 2009) over the territory. The reconversion of innactive spaces in rural areas into leisure-related ones in a quite common practice in contemporary times.The Spaniards beach is one of the local names given by locals to the Dam of Póvoa (Castelo de Vide), in northern Alentejo (Portugal). In the collective memory of the residents, the Dam (built in the 1920’s) is remembered for the many flowers surrounding the area. This Garden-style aesthetics has outlived the initial function of the Dam (to produce electric power). From the 1960’s to the 1980’s, it was also a popular leisure space for Spanish and Portuguese people. It is not a beach, but being inland, it was the closest thing to a beach the residents had. The centrality of this leisure space in the area only decayed after the construction of swimming pools in the nearby towns. Early in the begginning of 21st century a fire destroyed part of the natural floral landscape of the dam. Abandoned for some years, the place has still been appropriated by leisured people in day-trips (for sight-seeing, pic-nics), fishing competitions, caravan soujorns, and, since 2013, in a music and dance festival named Andanças (www.andancas.net). The research that underlies this paper was carried out between 2013 and 2016 by a team of anthropologists. An ethnography of the Dam and its uses, and of the festival and its participants was carried out. In our working-paper we higlight the main research findings achieved.

Creative Practices Around the Production of Cork

Cork, as a natural product provided by the bark of the cork oak tree, is an important staple of the Portuguese economy and important to Portuguese culture. It is a sustainable product with a positive ecological footprint, from harvesting to industrial production, with the advantage of creating a local economic model through regional labour activity and distribution. Within the balance between nature-human-economy to create a sustainable system, cork production in Portugal represents a human and social dimension. By focusing on that dimension and by creating an awareness of the cultural and social impact of the activity and by re-appraising the meaning of the material within the culture, the study reframes a consideration of the actual place of labour and production. The human, geophysical, historical, social, economic, ecological and cultural aspects of the place are observed as regards their relation to work or labour in that physical space. A pilot study is being developed in the village of Azaruja in the district of Évora, Portugal. In this small locality, cork is very important in terms of the relationships between the physical subsistence of their residents and the local natural resources, because it structures the place in its cultural, social and economical dimensions. This paper outlines the theoretical foundations, the process and the outcomes of the participatory ecodesign project titled Creative Practices Around the Production of Cork which was initiated by a Portuguese artist/design researcher and developed further through the collaboration with the other two authors, one a Portuguese visual artist/researcher and the other a Turkish fashion designer/theorist. The investigation focuses on questions that expand the notion of place for artists and designers, filtered through the lenses of manual labourers in order to understand their physical, social, cultural and economic relationship with the environment. To create the process of interaction with the place and the people, a creative collaborative dynamic is developed between the authors with their range of artistic sensibilities and the local population. To adopt a holistic notion of sustainability and cultural identity a process of investigation is designated to: (1) analyse, test and interpret - through the dissemination of life stories, visual representation of the place and the creation of cork objects - the importance of culture related to the labour activity of a local natural resource that determines and structures the region; (2) to give public recognition to those involved, taking into account their sense of belonging to the place and in order to show the value of their sustainable labour activities related to local natural resources; (3) to contribute to the knowledge of the place and to its dynamism through an aesthetic approach to labour activities. With reference to fields of knowledge such as anthropology, the social arts and sustainable design, a practice-based research is conducted with collaborative and participatory design methods to create an open model of interaction which involves local people in the realization of the project. Outcomes of this research will be presented in the paper as a survey analysis with theoretical conclusions.

Este guia procura promover o conhecimento sobre as espécies e comunidades piscícolas e ser uma ferramenta técnica de resposta a questões prioritárias em termos de conservação do património natural, gestão dos recursos hídricos e ordenamento do território. O âmbito deste trabalho de mestrado centra-se na ilustração de algumas das espécies de peixes tratadas, investigando e criando pela primeira vez uma representação rigorosa que promova a documentação e identificação destas, como ponto de partida para o trabalho a realizar para a totalidade das espécies a tratar no guia. O trabalho desenvolvido é um trabalho que se pode considerar inédito, na medida em que não existe, tanto quanto sabemos e após extensiva pesquisa bibliográfica neste domínio, nada publicado que se assemelhe aos níveis de rigor, detalhe e coerência entre todo o conjunto apresentado. O resultado pretendido para este guia é o de uma publicação de referência, de grande utilidade técnica e de cuidada comunicação visual. Nesse sentido foi também desenvolvido um layout gráfico, visando uma apresentação cuidada e apelativa dos conteúdos do guia, pretendendo contribuir para uma maior sensibilização dos vários públicos a que se destina; ABSTRACT: This Masters thesis is part of a larger project, developed by FFishGUL, the Freshwater Fish Group of the University of Lisbon, consisting of the edition of an illustrated guide to the freshwater fish of mainland Portugal. This guide aims to create a hitherto nonexistent tool to promote knowledge on Portuguese freshwater fish communities and species and help on the management of water resources and land-use planning. This Masters thesis is centered on the illustration of some of the guide’s fish species, aiming to study and create an accurate representation that will facilitate their correct identification. These illustrations serve as an example of the process that will be followed for the total guide’s species range. The developed work can be regarded as unprecedented, to the extent that there is not, as far as we know, and after extensive bibliographic research in this field, any published work resembling the levels of accuracy, detail and coherence of what is here presented. This guide intends to be a reference publication, of major technical utility and careful visual communication. In this sense a graphic layout was also developed, aiming a careful and attractive presentation of the guide’s contents and contributing to greater awareness of the various target audiences.

Plantas invasoras no sul de Portugal: uma abordagem biogeográfica

As espécies invasoras são uma das principais ameaças à biodiversidade causando impactes ecológicos, económicos e nos serviços dos ecossistemas. O conhecimento conjunto da dinâmica das séries de vegetação e da ecologia das plantas invasoras é uma ferramenta útil na recuperação ecológica de áreas invadidas e na prevenção de invasões. Este trabalho tem como objectivo principal averiguar a relação entre a distribuição das plantas invasoras e as comunidades vegetais terrestres do Sul de Portugal. Para tal, fez-se corresponder a distribuição de nove plantas invasoras selecionadas com as séries de vegetação e territórios biogeográficos, em 60 quadrículas com 1 Km2. A Província Lusitana-Andaluza Costeira revelou-se a mais invadida, com predomínio de Acacia dealbata, Acacia longifolia e Opuntia maxima no potencial climatófilo de sobreiral psamófilo; A. longifolia dominou no potencial edafoxerófilo de zimbral de Juniperus turbinata e A. dealbata e Arundo donax no potencial edafo-higrófilo de freixial. Com base nos resultados, estabeleceram-se áreas prioritárias para intervenção; INVASIVE PLANTS IN SOUTHERN PORTUGAL A BIOGEOGRAPHICAL APPROACH Abstract: Invasive species are one of the main threats to biodiversity worldwide and are responsible for negative impacts at ecological, economic and ecosystem services level. Complementarity between vegetation series dynamics and invasive plants ecology knowledge is essential to address ecological restoration and to prevent invasions. The main goal of this work is to investigate the relationship between invasive plants distribution and terrestrial plant communities of Southern Portugal. Fieldwork was conducted in 60 1 Km2 sampling plots and a correspondence was made between nine selected invasive plants and the vegetation series and the biogegraphic units The Andalusian-Lusitanian Coastal province was the most invaded biogeographic unit and revealed the dominance of Acacia dealbata, Acacia longifolia and Opuntia maxima in the cork oak psammophilous series; A. longifolia dominated in the maritime turbinate juniper edapho-xerophilous series and A. dealbata and Arundo donax in the ash edaphohygrophilous groves potential. Based on the results, priority areas for intervention were defined.

Condicionantes ecológicas que afectam o Sisão durante o início de um ano agrícola

Este estudo foi realizado durante o Outono de 2001, em três áreas agrícolas do Sul de Portugal e tem como objectivo determinar quais os factores que influenciam a selecção de habitat pelo Sisão no Outono. A amostragem baseou-se na realização de transectos a pé. A identificação das preferências de habitat e o desenvolvimento de modelos preditivos foi realizada recorrendo a modelação linear (GLM) e aditiva (GAM). Os resultados da análise à escala da paisagem indicaram que a espécie prefere restolhos de cereal e pousios. Adicionalmente, foram seleccionadas as áreas com melhores solos e mais próximas das linhas de drenagem. As análises relativas ao microhabitat sugerem que o Sisão utiliza preferencialmente áreas com vegetação herbácea baixa e com elevada disponibilidade de plantas verdes. Os resultados sugerem que a disponibilidade alimentar é ainda limitante durante esta época, pelo que a implementação de medidas agro-ambientais compreendendo a manutenção dos sistemas cerealíferos tradicionais e consequentemente dos restolhos e pousios nas áreas com solos mais produtivos, são as medidas adequadas para promover os habitats da espécie. ABSTRACT; This study was carried out in the autumn of 2001, in three cultivated areas of southem Portugal and aims to determine the factors that influence the habitat selection of the Little Bustard in that period of the year. Foot transects were used to locate Little Bustards. GLM and GAM modelling were performed to identify the species' habitat preferences and to develop explanative occurrence models. The results of the landscape analysis indicate that Little Bustards exhibit a preference for cereal stubbles and fallow lands. Additionally, birds were mostly found in fields with best soils and close to water drainage lines. Microhabitat analysis shows that birds seem to prefer short grassy vegetation, where the availability of green plants is higher. Results suggest that food availability is still limiting for the species at this season. Therefore, the implementation of agri-environmental schemes comprising the maintenance of traditional cereal farming and consequently stubbles and fallow land within areas with more productive soils, are adequate measures to promote suitable foraging habitats for the Little Bustard.

O papel das estruturas lineares, artificiais e naturais, como locais de refúgio de micromamíferos

Avaliámos a importância das bermas das estradas como áreas de refúgio para pequenos mamíferos, em paisagens Mediterrânicas intensivamente pastoreadas, e comparámos esta possível função das estradas como refúgio com o papel fundamental das galerias ripícolas como reservatórios de diversidade biológica. Para esse efeito, foram realizadas capturas de micromamíferos em dois segmentos de estrada e em duas ribeiras da região de Évora. Foram capturados 457 indivíduos de cinco espécies diferentes. Mus spretus foi a espécie mais capturada, seguida de Crocidura russula e Apodemus sylvaticus. M. spretus apresentou uma maior abundância nas bermas de estrada do que na vegetação ripicola, enquanto que a abundância de C. russula e A. sylvaticus era semelhante para ambos os habitats. O número de capturas das três espécies foi bastante superior dentro dos habitats lineares do que na matriz circundante. Os indivíduos de M. spretus eram maiores nas ribeiras, mas significativamente menores fora dos habitats lineares, e os indivíduos de C. russula apresentavam uma melhor condição corporal nas bermas das estradas. Tanto as estradas como as ribeiras exerceram um forte efeito de barreira aos movimentos dos micromamíferos. Concluímos então que as bermas das estradas actuam como habitat de refúgio em áreas sub-óptimas das paisagens Mediterrânicas. ABSTRACT: We assessed the importance of road verges as refuge areas for small mammals, in highly intensified grazed pastures on a Mediterranean landscape, and compared road function as refuge with the fundamental role of riparian galleries as reservoirs of biological diversity. For this purpose, a small mammal trapping study was undertaken on road verges and on small stream sides. We sampled two road segments and two streams in the vicinity of Évora, Portugal. We captured a total of 457 individuals of five different species. Mus spretus was the most common species captured, followed by Crocidura russula and Apodemus sylvaticus. M. spretus was more abundant on road verges than on riparian strips, whilst the abundance of C. russula and A. sylvaticus were similar in the two habitats. Captures of the three species were much higher inside both linear habitats than on the surrounding matrix. M. spretus were bigger on stream sites but significantly smaller outside the linear habitats and C. russula had better body conditions on roads. 8oth roads and streams exerted a strong barrier effect to small mammals' movements. We conclude that roadside verges act as refuge habitat in sub-optimal Mediterranean landscapes.

Social representations about the Portuguese adolescent alcohol consumption

Alcohol is currently the most widely consumed psychoactive substance in the world and Portugal is the second country where such consumption is greater, registering a large increase in consumption by young people. Currently continue still, beliefs, myths and prejudices that because they are well rooted culturally serve as good reasons for drinking. This study sought therefore to identify the myths associated by adolescents to alcohol consumption. A questionnaire was developed for this purpose (74 items, α = 0.947) and applied to a sample of 1176 adolescents schooled between 14 and 18 years old, with a return rate of 42.6% (margin of error of 5% for a confidence level of 95%) in the district of Beja, Portugal, in 2012. The collected data were statistically analyzed using measures of association, factor analysis and linear regression. The results show that many myths are unknown among adolescents, verifying the presence of many questions, among which stands out: alcohol "warm", "thirst quenching", "gives strength", "facilitates digestion" "whet the appetite", "is a medicine", "is aphrodisiac", "facilitates social relations", among others. Age and sex are variables significantly affected the myths and objectives of alcohol consumption. These results clearly point to the need to be disassembled beliefs and wrong conceptions about the effects of alcohol consumption, particularly in the school environment, reducing the risk of the consequences and promoting adolescent health, preventing any future dependence on this psychoactive substance.

Propolis components accountable for bactericidal accomplishment and antibiofilm activity

This study aimed at evaluating antimicrobial and antibiofilm activity of phenolic compounds present in propolis ethanol extracts (PEE). Seventy per cent ethanol extracts from seven types of propolis, one Green, two Red and four Brown collected in four Brazilian States were prepared and total phenolics, flavonoids, tannins and anthocyanins were assessed by high-performance liquid chromatography (HPLC). Minimum bactericidal concentration (MBC) and inhibitor effect on Staphylococcus aureus biofilm formation and capacity to disrupt established biofilms were assessed towards eight S. aureus isolates from milk of small ruminants with mastitis, one methicillin-resistant S. aureus (MRSA) and S. aureus ATCC 25923. To evaluate different propolis components accountability for bactericidal accomplishment and antibiofilm activity, the results were analysed by the non-parametric Spearman coefficient. Results of phenolic compounds were 216,21 to 312,08 gallic acid milligram equivalent per extract gram (mg EGA/g) of total phenolics, 55,08 to 140,6 quercetin milligram equivalent per extract gram (mg EQ/g) of flavonoids, 118,51 to 3766,16 catechin milligram equivalent per extract gram (mg EC/g) of tannins and 1,03 to 8,39 milligram per extract gram (mg/g) of anthocyanins. Red1 and Red2 showed higher tannin contents, while Red2 exhibited superior amount of anthocyanins and total phenolics. Brown3 presented higher flavonoid quantity. Green, Red1 and Red2 PEE showed the lowest levels of flavonoids, but the higher antimicrobial activity. Most PEE exhibit bactericidal activity at a concentration of 1.6 mg/mL. Brown4 PEE showed the worst capacity to inhibit S. aureus. Green PEE showed to be the most efficient in both preventing and disrupting biofilm. All PEE studied exhibited a better inhibitory activity prior-to than post-biofilm formation. According to non-parametric Spearman correlation analysis, there seems to be a significant negative correlation between the ability to disrupt biofilm and both tannins and anthocyanins contents.

Alinhamento das práticas de responsabilidade social com a estratégia das instituições de ensino superior: um referencial de governação socialmente responsável gerador de confiança e reputação organizacional

A responsabilidade social é considerada fundamental para a conquista de vantagens competitivas organizacionais. A integração dos seus princípios na estratégia da organização, apresenta-se como uma linha orientadora do foco na satisfação de necessidades das partes interessadas internas e externas. As actuais limitações orçamentais têm afectado significativamente as Instituições de Ensino Superior, nomeadamente as localizadas no interior de Portugal continental, o que dificulta ainda mais a crescente diminuição de estudantes sendo necessário a implementação de estratégias de captação de estudantes nos vários ciclos, fases de idade e locais de proveniência. O sistema de gestão da responsabilidade social, referenciado na NP 4469.1:2008, apresenta um grande desafio ao modelo de gestão das organizações que o implementam, já que este sistema de gestão tem o potencial de optimizar os interesses das diversas partes interessadas. O foco da instituição passa a ser os das suas partes interessadas, maximizando os seus impactes positivos e minimizando os seus impactes negativos em resultado das suas actividades e decisões. O aumento da eficácia organizacional e a equidade dos interesses das partes interessadas, podem clarificar as funções estratégicas das Instituições de Ensino Superior. Os programas e práticas de responsabilidade social implementados nas Instituições de Ensino Superior do interior de Portugal continental são assim estrategicamente vistos, como um factor de diferenciação positiva face às suas congéneres e em consequência, assumido como um factor para a sua sustentabilidade. A presente investigação procura identificar um modelo de governação socialmente responsável que se comprometa com a dinamização de uma estratégia que preveja práticas de responsabilidade social condutoras a aumentos na confiança e reputação organizacionais nos estudantes e colaboradores das Instituições de Ensino Superior. Tendo por base a abordagem de investigação qualitativa, realizaram-se estudos de caso em duas Instituições de Ensino Superior localizadas no Alentejo, recorrendo-se a várias fontes de informação: entrevistas a 45 entrevistados, entre elementos da governação, colaboradores e estudantes, análise documental e observação participante. Como técnica de tratamento dos dados utilizou-se a análise de conteúdo através do software Atlas Ti. Os resultados da investigação empírica permitem identificar que, as duas Instituições de Ensino Superior melhoraram em termos de visibilidade externa e interna, havendo entrevistados que referem uma melhoria na confiança e reputação em resultado da adesão a práticas de responsabilidade social. O líder de uma das Instituições de Ensino Superior é reconhecido pelos seus pares como de elevado compromisso para com os princípios da responsabilidade social enquanto que o outro líder não é reconhecido da mesma forma. Os estudantes entrevistados, não reconhecem vantagens em resultado das práticas de responsabilidade social tanto ao nível da confiança como reputação organizacional; ABSTRACT: Social responsibility is considered essential to the achievement of organizational competitive advantage. The integration of its principles in the organization's strategy, presents itself as a guiding line focus on meeting the needs of internal and external stakeholders. The current budgetary constraints have significantly affected the higher education institutions, further hindering the increasing decline of students being required to implement student recruitment strategies in the various cycles of age stages and places of origin. The management system of social responsibility, referenced in NP 4469.1:2008, presents a major challenge to the model of management of organizations implementing it, since this management system, has the potential to optimize the interests of the various stakeholders. The focus of the institution happens to be out of their stakeholders, maximizing its positive impacts and minimizing the negative impacts as a result of its activities and decisions. Increased organizational effectiveness and equity interests of stakeholders can clarify the strategic functions of the higher education institutions. Social responsibility programs and Social responsibility practices implemented in higher education institutions in the interior of mainland Portugal are so strategically seen as a positive differentiating factor compared to their counterparts and therefore assumed to be a factor in their sustainability. This research seeks to identify socially responsible governance model that is committed to the promotion of a strategy which envisages conducting social responsibility practices to increases in organizational trust and reputation among students and employees of higher education institutions. Based on the qualitative research approach, there were case studies in two higher education institutions located in the Alentejo, making use of several sources of information: interviews with 45 respondents, between elements of governance, employees and students, document analysis and participant observation. As data processing technique was used content analysis by instrumental Atlas Ti. The results of empirical research identifying that the two higher education institutions have improved in terms of internal and external visibility, with respondents who report an improvement in confidence and reputation as a result of adherence to Social responsibility practices. The leader of one of the higher education institutions are recognized by their peers as high commitment to the principles of social responsibility while the other leader is not recognized in the same way. Students do not recognize advantages as a result of social responsibility practices both in terms of trust and organizational reputation.
