A presente dissertação pretende compreender as origens e a actividade associada à capitania-mor do mar da Índia, considerado o segundo cargo mais relevante da estrutura político-militar do Estado Português da Índia, desde 1502 a 1564. Este cargo, transferido do reino para a Índia, ainda nos primórdios da presença portuguesa, em 1502, visou assegurar os interesses da Coroa na Ásia. Após a nomeação do primeiro vice-rei para a Índia, D. Francisco de Almeida, em 1505, este ofício foi desde logo disputado e requerido pelos governadores subsequentes. Na maioria das vezes era-lhes concedida a possibilidade de indicarem ao soberano quem pretendiam ao seu lado, para os auxiliar na realização do plano de expansão gizado pela Coroa. No entanto, ao monarca assistia a palavra final. Procuramos saber quem foram os oficiais que ocuparam a capitania e compreender que espaço era esse “Mar da Índia”. Considerado o controlo do mar como a base da afirmação e alargamento da presença portuguesa na Ásia, de acordo com os planos de expansão de D. Manuel I e D. João III, é relevante percebermos qual foi a área de autoridade desta capitania. Se o espaço é relevante, também as embarcações o são, por isso, tentamos perceber que tipos de embarcações faziam parte das armadas associadas a este ofício. Após o entendimento sobre o espaço e as embarcações, foi relevante percebermos os critérios da nomeação e as funções inerentes, as quais eram, sobretudo, do foro político-militar. Todavia, os poderes outorgados à capitania, de natureza marítima, foram por vezes alargados às praças portuguesas do Estado da Índia. Percepcionar de que forma e para que fins essa autoridade se ampliou também foi motivo de discussão. Compreender o estatuto social e o impacto do cargo nas trajectórias individuais, foram aspectos que foram tidos em linha de conta ao longo do nosso estudo. Tentamos igualmente avançar com hipóteses explicativas sobre o fim deste cargo. Com este estudo pretendemos compreender como a capitania-mor do mar da Índia fez parte do funcionamento da cúpula político-militar do Estado Português da Índia, ao longo de mais de meio século, como elemento estabilizador. Constatamos que o capitão-mor do mar também foi usado pelo rei, com o intuito de controlar o governador em funções.

ResumenHaciendo uso de la metodología prosopográfica y de un enfoque teórico de redes sociales, el presente artículo se propone investigar el funcionamiento social del conocimiento, así como sus mecanismos de transmisión en la sociedad colonial de Costa Rica. También se lleva a cabo una presentación documental de las principales líneas de evolución institucional de la educación en la época. Se llega así a constatar que el conocimiento estaba en manos de una estrecha red social de individuos conectados, enriquecidos y empoderados, que formaban parte de la elite política colonial, quienes lo vedaban sistemáticamente a otros sectores sociales de la época, y lo empleaban para apuntalar su posición social.AbstractBy means of a prosopographic study and using a social networks theoretical approach, this article explores the social functions of knowledge, as well as its ways of transmission in the Costarican colonial society. A documented presentation of the main traits of the evolution of the formal education in the period is also offered. As a result, the work concludes that knowledge was in the hands of a very narrow social network structured with very well connected individuals, who were also rich and politically powerful. These individuals used their position and their monopoly of knowledge to impede access to it to other social groups of the time, using it, at the same time, as a tool to sustain their social position.

Purpose The purpose of this paper is to develop and test an integrative services framework to investigate the role of perceived trade show effectiveness on overall trade show service outcome, conceptualised as the intention to purchase a related product after, rather than during, a show. Design/methodology/approach Drawing on the services marketing and trade show literature, the authors test a model of trade show effectiveness with data collected from 592 attendees at a major automotive trade show in a large metropolitan centre. Findings Results show that improving trade show visitors' perceived service quality positively affects visitor perceptions of trade show effectiveness. Furthermore, both trade show effectiveness and service quality directly influence future purchase intention. Research limitations/implications Employing a services theoretical framework to evaluate trade show visitor experiences provides an alternative to the traditional marketing communications approach. By viewing such visits as service encounters, managers must inevitably consider the effects of service quality and service outcomes in determining the likely success of their shows. The study primarily focuses on one large consumer show and therefore does not constitute a complete, nor necessarily representative, sample of the trade show industry. Originality/value The original contribution of the paper stems from the paucity of research conceptualising trade shows as services and the comparative lack of emphasis placed on visitors rather than exhibitors in the literature. The research not only has utility for trade show organisers but also provides necessary theory-based research in the trade show domain.

Knowledge is a commodity. It is a by-product of learning that involves the creation, sharing, processing and possible use of information in the mind of an individual. Knowledge management (KM) is, therefore, concerned with the effective implementation of such activities within the organisation. It is simply the process of leveraging organisational knowledge to deliver a long-term competitive advantage. This paper presents the results of an empirical research investigation into the interaction between different KM activities within the context of construction contracting organisations. The different KM activities include: responsiveness to the knowledge of business environment, knowledge acquisition, knowledge dissemination, and knowledge application. A questionnaire survey was administered to investigate the opinions of construction professionals regarding the intensity of activities currently implemented by their organisations to facilitate knowledge capturing, sharing and application. A total of 149 responses were then used to statistically examine the inter-relationships between the different KM activities as practised by contracting organisations in Hong Kong. The paper presents and discusses the survey findings and proposes recommendations for improving the effectiveness of current KM practices.

With the increasing popularity of the galvanic replacement approach towards the development of bimetallic nanocatalysts, special emphasis has been focused on minimizing the use of expensive metal (e.g. Pt), in the finally formed nanomaterials (e.g. Ag/Pt system as a possible catalyst for fuel cells). However, the complete removal of the less active sacrificial template is generally not achieved during galvanic replacement, and its residual presence may significantly impact on the electrocatalytic properties of the final material. Here, we investigate the hydrogen evolution reaction (HER) activity of Ag nanocubes replaced with different amounts of Pt, and demonstrate how the bimetallic composition significantly affects the activity of the alloyed nanomaterial.
