The effect of university culture and stakeholders' perceptions on university-business linking activities

The present work discusses the effects of university culture and structure on university-business relations, focusing on knowledge transfer activities. It puts forward the thesis that when links between university and business are introduced into the university system as a turn-key proposition rather than as developmental process, the prevailing university culture and structure will exert resistance against change and will oppose the creation of appropriate structures to promote them, with deleterious effects for the university.

Increased connexin43 expression in human sphenous veins in culture is associated with intimal hyperplasia

Résumé Objectif : L'hyperplasie intimale est un processus de remodelage vasculaire qui apparaît après une lésion vasculaire. Les mécanismes impliqués dans l'hyperplasie intimale sont la prolifération, la dédifférentiation et la migration des cellules musculaires lisses depuis la média vers l'espace sous-intimal. Nous avons émis l'hypothèse que les jonctions communicantes de type gap, qui coordonnent certains processus physiologiques tels que la croissance et la différentiation cellulaire, pouvaient participer au développement de l'hyperplasie intimale. Méthodes : Des segments de veines saphènes humaines prélevées chirurgicalement lors de pontages, ont été ouverts longitudinalement avec la surface luminale placée vers le haut et maintenus en culture pendant 14 jours. Des fragments veineux ont été préparés pour une évaluation histologique, pour des mesures de l'épaisseur de la néointima, et pour des analyses immunocytochimiques de l'ARN messager ainsi que des protéines. Résultats : Parmi les 4 connexines (Cxs 37, 40, 43 et 45) qui forment les jonctions communicantes dans les veines, nous avons focalisé notre étude sur l'expression des Cxs 43 et 40; nous avons démontré que la Cx43 est exprimée dans les cellules musculaires lisses et les cellules endothéliales alors que la Cx40 est uniquement présente dans l'endothélium. Après 14 jours en culture, des analyses histomorphométriques ont montré une augmentation significative de l'épaisseur de l'intima démontrant la présence d'hyperplasie intimale. Une analyse temporelle a révélé une augmentation progressive de la Cx43 jusqu'à une augmentation maximale de six à huit fois au niveau de l'ARN messager et des protéines après 14 jours en culture. Au contraire, l'expression de la Cx40 n'était pas modifiée. Des analyses par immunofluorescence ont montré également une augmentation de la Cx43 dans les membranes des cellules musculaires lisses de la média. Le développement de l'hyperplasie intimale in vitro est diminué en présence de fluvastatin et cette diminution est associée à une réduction de l'expression de la Cx43. Conclusions : Ces données démontrent que la Cx43 est augmentée in vitro pendant le processus d'hyperplasie intimale et que la fluvastatin prévient cette induction. Ces résultats suggèrent un rôle crucial joué par la communication intercellulaire impliquant la Cx43 dans la veine humaine durant le développement de l'hyperplasie intimale. Abstract Objective: Intimal hyperplasia is a vascular remodelling process that occurs after a vascular injury. The mechanisms involved in intimal hyperplasia are proliferation, dedifferentiation, and migration of medial smooth muscle cells towards the subintimal space. We postulated that gap junctions, which coordinate physiologic processes such as cell growth and differentiation, might participate in the development of intimal hyperplasia. connexin43 (Cx43) expression levels may be altered in intimal hyperplasia, and we therefore evaluated the regulated expression of Cx43 in human saphenous veins in culture in the presence or not of fluvastatin, an inhibitor of 3-hydroxy-3-methylglutaryl-coenzyme A reductase activity. Methods: Segments of harvested human saphenous veins, obtained at the time of bypass graft, were opened longitudinally with the luminal surface uppermost and maintained in culture for 14 days. Vein fragments were then processed for histologic examination, neointimal thickness measurements, immunocytochemistry, RNA, and proteins analysis. Results: Of the four connexins (Cx37, 40, 43, and 45), we focused on Cx43 and Cx40, which we found by real-time polymerase chain reaction to be expressed in the saphenous vein because they are the predominant connexins expressed by smooth muscle cells and endothelial cells. Afrer 14 days of culture, histomorphometric analysis showed a significant increase in the intimal thickness as observed during the process of intimal hyperplasia. Atime-course analysis revealed a progressive upregulation of Cx43 to reach a maximal increase of sixfold to eightfold at both transcript and protein levels after 14 days in culture. In contrast, the expression of Cx40, abundantly expressed in the endothelial cells, was not altered. Immunofluorescence showed a large increase in Cx43 within smooth muscle cell membranes of the media layer. The development of intimal hyperplasia in vitro was decreased in presence of fluvastatin and was associated with reduced Cx43 expression. Conclusions: These data show that Cx43 is increased in vitro during the process of intimal hyperplasia and that fluvastatin could prevent this induction, supporting a critical role for Cx43-mediated gap-junctional communication in the human vein during the development of intimal hyperplasia.

Do institutions and culture matter for business cycles?

We examine the relationship between institutions, culture and cyclical fluctuations for a sampleof 45 European, Middle Eastern and North African countries. Better governance is associated withshorter and less severe contractions and milder expansions. Certain cultural traits, such as lack ofacceptance of power distance and individualism, are also linked business cycle features. Businesscycle synchronization is tightly related to similarities in the institutional environment. Mediterraneancountries conform to these general tendencies.

Dimensions of national culture and the accounting environment -The Spanish case-

Gray (1988) has put forward a hypothesis on how a national accountingenvironment might reflect the cultural dimensions identified by Hofstede (1980, 1983). A number of studies have tested Gray's hypothesis, including one by Pourjalali and Meek (1995) which identified a match between changes in cultural dimensions and the accounting environment in Iran following the revolution. In this paper we replicate this work in the context of Spain following the death of Franco in 1975 and the emergence of a democratic constitution in 1978. Specifically, we: 1) Consider Gray's hypothesis built on Hofstede's cultural dimensions and review some empirical tests of the hypotheses.2) Building on the work of Hofstede and Gray, we: put forward some hypotheses on how we would expect cultural dimensions to change in Spain with the transition to democracy.3) Review developments in accounting in Spain following the transition to democracy, in order to identify how well these fit with our hypotheses.

Risk reduction practices in men who have sex with men in Switzerland: serosorting, strategic positioning, and withdrawal before ejaculation.

The aim of this study was to identify predictors of intentional use of the HIV risk reduction practices of serosorting, strategic positioning, and withdrawal before ejaculation during unprotected anal intercourse (UAI) with casual partners. A cross-sectional survey pertaining to the Swiss HIV behavioral surveillance system, using an anonymous self-administered questionnaire, was conducted in 2007 in a self-selected sample of men having sex with other men (MSM). Analysis was restricted to participants with UAI with casual partner(s) (N = 410). Logistic regression was used to estimate factors associated with intentional use of serosorting, strategic positioning, and withdrawal before ejaculation. In the previous 12 months, 71% of participants reported having UAI with a casual partner of different or unknown HIV-status. Of these, 47% reported practicing withdrawal, 38% serosorting, and 25% strategic positioning. In the 319 participants with known HIV-status, serosorting was associated with frequent Internet use to find partners (OR = 2.32), STI (OR = 2.07), and HIV testing in the past 12 months (OR = 1.81). Strategic positioning was associated with HIV-status (OR = 0.13) and having UAI with a partner of different or unknown HIV-status (OR = 3.57). Withdrawal was more frequently practiced by HIV-negative participants or participants reporting high numbers of sexual partners (OR = 2.48) and having UAI with a partner of unknown or different serostatus (OR = 2.08). Risk reduction practices are widely used by MSM, each practice having its own specificities. Further research is needed to determine the contextual factors surrounding harm reduction practices, particularly the strategic or opportunistic nature of their use.

Maintaining dendritic cell viability in culture.

When mouse dendritic cells (DCs) are isolated from tissues, purified and placed in a nutritive culture they die more rapidly than would be expected from their normal turnover in vivo. This can distort culture assays of DC function. We therefore tested several approaches to prolonging DC survival in culture. Of several cytokines tested granulocyte-macrophage colony stimulating factor was most effective at preserving the viability of conventional DCs (cDCs) but was ineffective for plasmacytoid DCs (pDCs). Surprisingly, Fms-like tyrosine kinase 3 ligand, crucial for DC development, produced only a marginal improvement in DC survival in culture, and interleukin-3, reported to prevent apoptosis of human pDCs, produced only a minor improvement in survival of mouse DCs. Genetic manipulation of cell death pathways was also tested, to avoid activation effects exerted by cytokine signalling. The isolation of DCs from mice overexpressing Bcl-2 was especially effective in maintaining pDC viability but gave a lesser improvement in cDC viability. DCs isolated from Bim(-/-)Noxa(-/-) mice also showed improved culture survival, but in this case with pDCs showing the least improvement.

Motivação e desempenho dos funcionários da administração pública cabo-verdiana actual

The process of changes that have been taking place in contemporary world reaches undoubtedly to the public sector. The quest for a new public management, that seeks to provide quality and effective services to the citizens, has been the target of contemporary State. Within this framework, the study of people inside publics organizations becomes strategic. Knowledge is generated, processed, and communicated at great speed, taking society to adopt new approaches. In order to meet the challenges of the new millennium, organizations must thing more of people and, above all, they must be more concerned with creating incentives that can motivate their collaborators to achieve not only the objectives of the organization but also personal objectives of each individual, since there is no point in gaining profit and having productivity if the organization do not develop policies and practices that focus on the human being. Motivation implies accomplishment feelings and professional recognition, expressed by means of executing tasks and activities that are sufficiently challenging and meaningful to the job. The truth is that the adoption of a public management focused on quality requires changes in organization culture, requiring mainly motivation, which leads to efforts, dedication, persistence, and commitment. This work is intended to research motivation as a tool to achieve productivity and excellence in the performance of activities in Cape Verdean Public Administration. To achieve the aim of this work, a bibliographical research on Human Resources Administration as well as different theories related to work motivation in organizations was conducted. The inquisitive method was used based upon a written questionnaire aimed at obtaining data referring to motivation of Public Administration workers.

Comportamentos de saúde e doença numa comunidade Cabo-Verdiana em Lisboa

O objetivo foi compreender como os indivíduos se comportam em termos de saúde e o que fazem em caso de doença. Análise comparativa realçou semelhanças e divergências de práticas de saúde ou em caso de doença. O estudo foi efetuado numa amostra de 40 cabo-verdianos da primeira geração residentes na região de Lisboa, dividida em subgrupos: grupo social, geração e genero. Baseou-se em metodologia qualitativa com entrevistas semi-estruturadas. As práticas analisadas foram agrupadas em preventivas e de saúde, práticas utilizadas em episódios de doença, recursos para prevenção e tratamento, utilização de remédios caseiros e outros recursos ou terapeutas. Indivíduos experimentaram, ao nível das práticas, três sistemas de saúde que coexistiam em Cabo Verde, oficial, popular e tradicional e o recurso à religião. O discurso acerca das práticas de saúde e de doença demonstrou existirem diferenças, em alguns aspectos, entre grupos sociais e entre generos e gerações. Práticas de saúde destes imigrantes são idênticas às dos portugueses em contextos socioeconomicos semelhantes. Resultados sugerem existência de diferenças entre grupos sociais relativamente às práticas, na esfera da saúde e da doença. Mais que cultura e etnicidade, que se moldam às condições materiais de existência, neste estudo, o nível socioeconomico determinou as maiores diferenças a interferir nas práticas de saúde e doença, de grupo com cultura de base comum. Em geral, os indivíduos sobrevalorizaram sua identidade étnica e cultura de origem. Pertencimento a grupos sociais diferentes dá origem a partilha do sentimento de pertença cultural, mas não a comportamentos e práticas idênticos.

Motivação e desempenho dos funcionários da administração pública cabo-verdiana actual

O processo de mudanças que vem acontecendo no mundo contemporâneo alcança, inevitavelmente, o sector público. A busca de uma nova gestão pública, que procure prestar serviços ao cidadão com qualidade e eficiência tem sido o alvo a ser alcançado pelo Estado contemporâneo. Dentro desse prisma o estudo das pessoas dentro das organizações públicas apresenta-se como estratégico. O conhecimento é gerado, processado e comunicado a grande velocidade, o que leva a sociedade a assumir novas posturas. Para enfrentar os desafios do novo milénio, as organizações terão que pensar mais nas pessoas e sobretudo, preocupar-se mais em criar estímulos que motivem os colaboradores para alcançarem tanto os objectivos da organização quanto os objectivos pessoais de cada um porque não adianta obter lucro e produtividade se a organização não desenvolver políticas e práticas que privilegiam o ser humano. Motivação envolve sentimentos de realização e de reconhecimento profissional, manifestado por meio de exercícios das tarefas e actividades que oferecem suficiente desafio e significado para o trabalho. A verdade é que a adopção de uma gestão pública focada na qualidade requer mudanças na cultura organizacional, exigindo principalmente motivação, que conduz ao esforço, dedicação, persistência e comprometimento. Com o presente trabalho pretende-se investigar a motivação como uma ferramenta para alcançar a produtividade e a excelência no desempenho das actividades na Administração Pública Cabo-verdiana. Para alcançar o objectivo deste trabalho, fez-se uma pesquisa bibliográfica sobre a Administração dos Recursos Humanos e sobre as diversas teorias relacionadas com a motivação para o trabalho nas organizações. Utilizou-se o método inquisitivo baseado num interrogatório escrito para se obter dados referentes a motivação dos funcionários da Administração Pública.
