Context aware M-commerce services: C-IOB model approach

Context-aware computing is useful in providing individualized services focusing mainly on acquiring surrounding context of user. By comparison, only very little research has been completed in integrating context from different environments, despite of its usefulness in diverse applications such as healthcare, M-commerce and tourist guide applications. In particular, one of the most important criteria in providing personalized service in a highly dynamic environment and constantly changing user environment, is to develop a context model which aggregates context from different domains to infer context of an entity at the more abstract level. Hence, the purpose of this paper is to propose a context model based on cognitive aspects to relate contextual information that better captures the observation of certain worlds of interest for a more sophisticated context-aware service. We developed a C-IOB (Context-Information, Observation, Belief) conceptual model to analyze the context data from physical, system, application, and social domains to infer context at the more abstract level. The beliefs developed about an entity (person, place, things) are primitive in most theories of decision making so that applications can use these beliefs in addition to history of transaction for providing intelligent service. We enhance our proposed context model by further classifying context information into three categories: a well-defined, a qualitative and credible context information to make the system more realistic towards real world implementation. The proposed model is deployed to assist a M-commerce application. The simulation results show that the service selection and service delivery of the system are high compared to traditional system.

A context aware collaborative service provisioning system for mobile-commerce

In the process of service provisioning, providing required service to the user without user intervention, with reduction of the cognitive over loading is a real challenge. In this paper we propose a user centred context aware collaborative service provisioning system, which make use of context along with collaboration to provide the required service to the user dynamically. The system uses a novel approach of query expansion along with interactive and rating matrix based collaboration. Performance of the system is evaluated in Mobile-Commerce environment. The results show that the system is time efficient and perform with better precision and recall in comparison with context aware system.

El trabajo informal está en aumento y es necesario reformular las políticas de empleo

Con el agotamiento de la licuación de salarios se desaceleró la generación de empleo en Argentina, un fenómeno que -aunque coincidente- ha sido independiente de la crisis económica mundial. Las perspectivas del mercado laboral para 2009 exhiben una clara tendencia al deterioro en la calidad de los empleos, por lo que el empleo informal podría llegar al 40% a fin de año. En este contexto, aumenta la pertinencia de propuestas para mejorar el ambiente de negocios, incentivar el registro de las pequeñas empresas y fortalecer los programas sociales para eliminar la pobreza

Histoire philosophique et politique : des établissemens et du commerce des européens dans les deux Indes

Guillaume Raynal, historiador e filósofo francês, nasceu em Saint-Geniez-en Rouergue em 11 de abril de 1713 e morreu em Choillot, em 6 de março de 1796. Estudou no Colégio dos Jesuítas de Pézenas, distinguindo-se como pregador e professor. Abandonou o hábito jesuita para se dedicar à filosofia e à história, publicando numerosos artigos no Mercure de France. Tendo sido alvo de um mandado de prisão, refugiou-se na Prússia e mais tarde na Rússia; retornou à França em 1787. ‘Histoire philosofique et politique’ foi publicada simultaneamente pelo mesmo editor em duas impressões, contendo cinco volumes a primeira e dez volumes a segunda. Foi uma das obras que mais ínfluenciou o movimento da Revolução Francesa, tendo o autor utilizado opiniões e, eventualmente, a colaboração de Diderot e Holbach, entre outros contemporâneos. Proibido na França e ai queimado em 1781, este importante trabalho de Raynal teve mais de trinta edições num periodo de vinte anos e foi traduzido para quase todos os idiomas europeus. Segundo Borba de Moraes, ‘esta edição de Genebra é a melhor e mais bela’. Na impressão de dez volumes existentes na Biblioteca da Câmara, a seção referente ao Brasil encontra-se no volume 5.

Informal fish retailing in rural Egypt: Opportunities to enhance income and work conditions for women and men

Poor rural consumers benefit from Egypt’s aquaculture sector through access to small and medium-sized farmed tilapia sold by informal fish retailers, many of whom are women. In fact, informal fish retail is the main, if not only, segment of the farmed fish value chain where women are found. This report aims to inform current and future strategies to improve conditions in informal fish retail by understanding in more depth the similarities and differences in employment quality and outcomes across different fish retailers. It is particularly focused on identifying whether and how gender inequality influences different dimensions of the work, and whether women and men have similar outcomes and employment conditions. This knowledge will help to design interventions to overcome gender-based constraints, as well as approaches that address shared obstacles and include both women and men in gender-responsive ways to ensure that all of those involved in the sector benefit.
