Designing dynamic distributed cooperative Human-Machine Systems

The paper presents a new approach to the development of cooperative human-machine systems in the Transportation domain which is currently researched in the European project D3CoS. A necessary precondition for the acceptance of cooperative human-machine systems with shared control is the confidence and trust of the user into the system. D3CoS tackles this important issue by addressing the cooperative system as the object and the target of the system development process. This new perspective, along with corresponding innovative methods, techniques and tools, shall allow the identification of optimal task and authority sharing approaches supported by intuitive human-machine interaction and user interfaces at an early stage of system development. This will support powerful teamwork between humans and machines or between machines and machines that is transparent, intuitive and easy to understand. The paper describes the research dimensions for the development of the methods, techniques and tools as well as first results.     

The logic of strategic ignorance

Ignorance and knowledge are often thought of as opposite phenomena. Knowledge is seen as a source of power, and ignorance as a barrier to consolidating authority in political and corporate arenas. This article disputes this, exploring the ways that ignorance serves as a productive asset, helping individuals and institutions to command resources, deny liability in the aftermath of crises, and to assert expertise in the face of unpredictable outcomes. Through a focus on the Food and Drug Administration's licensing of Ketek, an antibiotic drug manufactured by Sanofi-Aventis and linked to liver failure, I suggest that in drug regulation, different actors, from physicians to regulators to manufacturers, often battle over who can attest to the least knowledge of the efficacy and safety of different drugs - a finding that raises new insights about the value of ignorance as an organizational resource.     

Health and safety of students in vocational training in Quebec: a gender issue?

Health and safety issues in a vocational training center were explored in this study. Several sources and methods were used: group interviews with students in traditionally female [F] and male [M] trades, i.e. hairdressing (7 F) and automated systems electromechanics (8 M, 1 F); self-administered questionnaires on injuries sustained at the school; observations of activities in these programs; and analysis of ministerial documents. Findings indicate that the partially divergent ways that OHS is addressed in these programs cannot be explained only by the specific characteristics of the two trades. Some aspects put female students in hairdressing at a disadvantage: status accorded to OHS in the study programs, learning activities, and conditions for learning and managing prevention and injuries. The discussion focuses on a gender-differentiated analysis, the importance of improving the way OHS is addressed in the programs, in particular, those primarily involving female students, and the need to pursue research. In addition, the results from individual interviews with women (5 F) training for non-traditional trades lead to discussion on the interrelated effects of sex-based gender and professional gender.     

中国经济何时见底？

中国第一季度的经济增长率低于预期8．1％，是2009年第一季度以来的最低增速。增长放缓的主要原因是出口和房地产投资的下滑。而这也使得正在致力于让经济软着陆的中国政府面临着更加复杂的局面。政府今年的目标是增长率为7．5％，尽管低于前些年的目标值，但是仍然是全球经济的亮点所在。中国经济的有力增长和强劲的公共金融与美欧的局面...     

From the "terrain" to "territory": which contributions from mobility and bus drivers' activity towards local development?

The focus of the present analysis is on the work of drivers in the public road passenger transportation sector in Portugal and on its specific contribution to local development. This approach dissociates itself from the one that places mobility as a "paradigm" of the contemporary societies and considers that the increase in mobility registered in the latter years is, in itself, revealing of development. For field work, a public transportation line, in an urban context, and a network of lines, in a rural context were chosen. In each of these contexts, the drivers' work was analyzed in real situations and semi-structured interviews were held with 16 of them: ten drivers in an urban context and six in a rural context. Considering the point of view of the work activity, enabled us to abandon the dominant perspectives that tend to highlight the social inequality of the mobility conditions (between those who use a private vehicle and those who need to use public transportation), to reflect on the characteristics of the mobility spaces which benefit or limit it, contributing to other inequalities. What is the importance of the space for mobility besides its support? How is it considered in the drivers' work?     

当代中国的音乐及社会差序——京剧票友会与摇滚乐队“派对”比较研究

本文主要探讨当代中国的两种音乐活动形式——京剧票友会以及摇滚乐队派对。这两种音乐形式虽然在风格上截然不同,但是两种社团在结构上却存在着一定的相似性。这两种活动形式基本上都具有我们所称之为＂为位＂（positioning）的行为,参与者由此在音乐活动中找到他们各自的位置。而且,两种活动形式都涉及到＂外来者的融入＂（outsider integration）,即允许陌生人的参与并在活动中找到他们的位置。
