Context-awareness for mobile sensing: a survey and future directions

The evolution of smartphones together with increasing computational power have empowered developers to create innovative context-aware applications for recognizing user related social and cognitive activities in any situation and at any location. The existence and awareness of the context provides the capability of being conscious of physical environments or situations around mobile device users. This allows network services to respond proactively and intelligently based on such awareness. The key idea behind context-aware applications is to encourage users to collect, analyze and share local sensory knowledge in the purpose for a large scale community use by creating a smart network. The desired network is capable of making autonomous logical decisions to actuate environmental objects, and also assist individuals. However, many open challenges remain, which are mostly arisen due to the middleware services provided in mobile devices have limited resources in terms of power, memory and bandwidth. Thus, it becomes critically important to study how the drawbacks can be elaborated and resolved, and at the same time better understand the opportunities for the research community to contribute to the context-awareness. To this end, this paper surveys the literature over the period of 1991-2014 from the emerging concepts to applications of context-awareness in mobile platforms by providing up-to-date research and future research directions. Moreover, it points out the challenges faced in this regard and enlighten them by proposing possible solutions

The process of hospital consolidation: a case study in Anhui Province, China

JEL: I11, I18, M1, M54Hospital consolidation is an important topic both in theoretical research and practical exploration in the healthcare sector as it allows for the improvement of the utilization efficiency of medical resources and for the optimization of cost reduction. Based on the strategic management theory, especially the resource-based theory, this thesis makes an in-depth analysis of the strategic choices of the First People‘s Hospital group of Hefei City, Anhui Province, China. Combining with the process of China‘s health system reform, the motivating factors of establishing hospital groups, the basic concept of hospital groups and modes are reviewed while the reasons and background for public hospitals consolidation in China are introduced. Under this setting, the thesis studies the motivations behind strategic choices and incentives towards consolidation as well as the environment and the strengths and weaknesses of the internal resources of the hospital. Based on the case study method, 25 semi-structured interviews to 25 experts and participants and field visits were conducted for data collection. The research shows that the consolidation strategy followed by the hospital allows for its sustainable development. However, in identical situations, for positive results to be achieved, a core member of the group should be selected to lead the consolidation process during the transition period and to balance the relationship between centralization and decentralization while respecting each specific situation The analysis of the strategic consolidation of the hospital studied allowed for the identification of difficulties and challenges, which may serve as a theoretical base for the practice of other organizations undergoing a similar processA consolidação de unidades hospitalares é um tópico de investigação importante para a teoria e para a prática, pois permite reorganizar os recursos médicos através da sua utilização eficiente e da optimização da redução de custos. Com base na teoria da gestão estratégica e em especial na teoria dos recursos, esta tese analisa em profundidade as escolhas estratégicas com que se debateu um grupo hospitalar da cidade de Hefei, província de Anhui na China: o First People‘s Hospital Group. Tendo como base o processo de reforma do sistema de saúde na China, a tese estuda as motivações inerentes à tomada de decisão, bem como os incentivos à consolidação. São analisados os pontos fortes e fracos do hospital, os seus recursos principais e a envolvente procurando-se entender as escolhas estratégicas que levaram à consolidação. A tese utiliza o método do estudo de caso tendo sido realizadas 25 entrevistas semiestruturadas a peritos e participantes no processo bem como diversas visitas que permitiram observação direta. A investigação demonstra que a estratégia de consolidação permite assegurar o desenvolvimento sustentado do hospital mas, para isso, a melhor opção é escolher um dos membros do grupo para assumir um papel de liderança durante o período de transição e cuidar do equilíbrio da relação entre centralização e descentralização sem descurar a especificidade da situação local. A análise da consolidação estratégica do hospital estudado permitiu ainda identificar as dificuldades do processo contribuindo com uma base teórica que poderá ser útil ao desenvolvimento de outras organizações em idêntica situação

The functions of visual management

Visual Management has been evolving and effectively employed in some manufacturing and service organisations for a long time. In order to facilitate a cross-industrial learning process and to advance in detailed research the understanding of how the Visual Management concept may serve in an organisation is necessary. The aim of this paper is to identify Visual Management functions and the theoretical base for the construction industry. A detailed literature review and an analysis of the findings were performed accordingly. The necessity of a holistic approach in order to make more use of the Visual Management process and some research opportunities were identified

Systems Engineering

The book "Systems Engineering: Practice and Theory" is a collection of articles written by developers and researches from all around the globe. Mostly they present methodologies for separate Systems Engineering processes; others consider issues of adjacent knowledge areas and sub-areas that significantly contribute to systems development, operation, and maintenance. Case studies include aircraft, spacecrafts, and space systems development, post-analysis of data collected during operation of large systems etc. Important issues related to "bottlenecks" of Systems Engineering, such as complexity, reliability, and safety of different kinds of systems, creation, operation and maintenance of services, system-human communication, and management tasks done during system projects are addressed in the collection. This book is for people who are interested in the modern state of the Systems Engineering knowledge area and for systems engineers involved in different activities of the area. Some articles may be a valuable source for university lecturers and students; most of case studies can be directly used in Systems Engineering courses as illustrative materials

Prevention at work and stress evaluation in France and in Italy / La prévention sur les lieux de travail et l’évaluation du stress en France et en Italie / Prevenzione nei luoghi di lavoro e valutazione dello stress in Francia e in Italia

A European directive, transposed into the legal systems of the member States, steers towards an idea of prevention that is primary, general, programmed and integrated in work design. The interpretation of norms and the guidelines of institutions devoted to health and safety in the workplace direct, however, towards the management of existing risks. This is particularly evident as far as stress and the so called psycho-social risks are concerned. Even the approaches of disciplines regarding work follow the same trend. A real and effective protection of well-being appears to be neglected, and this is confirmed by statistics about physical and psychological damages to workers. The contributions in this collection concern France and Italy, where, however, internationally recognized approaches, allowing primary prevention interventions on work, have been developed
