浅析施工管理与施工安全

<正>一、概述《中华人民共和国安全生产法》第三条明确规定:"安全生产管理,坚持安全第一、预防为主的方针。"《中华人民共和国建筑法》第三十六条明确规定:"建筑工程安全生产管理必须坚持安全第一、预防为主的方针。"以法律形式确立的这个方针,是整个安全生产活动的指导原则。"安全第一,预防为主"是我国劳动保护的基本方针。事故一旦发生,其后果不堪设想。因此,防患于未然,把预防措施落到实处,是施工企业的一项十分重要的工作。二、加强施工现场安全技术措施施工机械及电气焊等特种作业工种等须由有资格证的专业人员操作,尤其一些危险性较大的项目施工时,要加强

An assessment and ranking of barriers to doing environmental business with China

The transfer of environmental goods and services to China will increasingly be of importance to developed nations as the demand for environmental management services increases in China. A review of the literature on technology transfer to China revealed a range of well recognized and commonly known constraints to transferring technologies to China. There were gaps in the literature in relation to the concerns that environmental professionals have regarding technology transfer to China, as there is limited information on the transfer in environmental goods and services to China. A survey of the non‐trade barriers and their practical impact on the transfer of environmental technologies and goods and services to China, focusing on Australian suppliers, was undertaken to address these gaps. The survey, which was developed from barriers to technology transfer already described in the extensive research addressing the wider issues of technology transfer to China, targeted environmental professionals but also included other professionals with interests in transferring environmental goods and services to China. From the survey, the highest priority barriers to transferring environmental goods and service to China were identified, and those that are most likely to limit Australian vendors of environmental goods and services in their technology transfers to China were protection of intellectual property (IP), limitations of the rule of law, fragmentation and bureaucracy of the Chinese government and establishing appropriate level of ownership (of environmental goods and services providers in China). Examples of Australian experience were also examined, which confirmed these barriers to providing the needed technology and innovation to manage China's increasing environmental impacts. The research also shows that the barriers identified do not appear to be unique to transfer of environmental goods and services but rather generic to the transfer and adoption of Australian technology into China.

The Familiar Face of the State: Affect,Emotion and Citizen Entitlements in Dehradun,India

Municipal Councillors (MCs) are the ‘familiar face of the state’ in Dehradun, India: the first port of call for citizens seeking to claim entitlements from the state. The way MCs respond to the requests of their constituents is a major factor in the uneven distribution of government welfare and services. This article seeks to contribute to understandings of citizen entitlements by drawing attention to the role of affect and emotion in shaping the interactions between MCs and voters. I examine the ways citizens consciously or unconsciously engender emotions and affective responses, and the effect these have in mobilizing MCs. Attention to the, at times, involuntary nature of these responses suggests a need to go beyond the instrumental and calculating motivations of municipal councillors, to consider the way they are compelled and animated to meet the demands of some citizens, but not of others. The capacity to affect, and the ways one is affected, are tied to the social identities and self-making projects of both the MC and the voter, resulting in an uneven (mal)distribution of state resources. A focus on affective configurations in urban governance thereby reveals heretofore overlooked determinants of unequal access to urban resources and services.

Sowing Seeds of Displacement: Gentrification and Food Justice in Oakland,CA

Green gentrification is the process through which the elimination of hazardous conditions or the development of green spaces is mobilized as a strategy to draw in affluent new residents and capital projects. Based on observations and interviews in Oakland, California, we argue that food justice organizations seeking to promote access to healthy food in low-income communities can unwittingly create spaces that foster this process. Despite a desire to serve long-term residents, activists embody a hip green aesthetic that is palatable to affluent whites and can be appropriated by urban boosters to promote the neighborhood. We use this process as a lens to theorize links between food and green gentrification, highlighting the importance of food to cities’ efforts to brand themselves as ripe for redevelopment, and understand green gentrification as a racialized process tied to cultural foodways. We also attend to the practical stakes for food justice activism, arguing that a clear understanding of green gentrification and food justice activists’ unwitting role in it can help the latter to attempt to mitigate their culpability and seek to develop broad inclusive strategies for locally led development without displacement.     

分布式存储系统调查

Reprint of “Sensitive translations: Sensitive dimension and knowledge within two craftsmen's workplaces”

In our paper we address the issue of the relations between knowledge and the sensitive dimension by taking into account and comparing the contribution to the production of a chair deployed by two craftsmen working within the Italian design furniture industry sector.Relying on an ethnographic account of their work, we have been able to describe in detail the way in which the interaction among the bodies of the two craftsmen and those of the artifacts they contribute to develop takes place and gives way to innovation.By taking into account the role of bodies and the sensitive dimension we outline a contribution to Actor-Network Theory and its theory of knowledge.Indeed, in this article we propose a model of working knowledge in order to account for corporal interaction on the workplace. In our model there are two axes to describe the interactions among bodies. In the first one interaction moves from detail to the whole. In the second, interaction moves from an engaged position to a disengaged one. In so doing, we are able to draw a space of corporal knowledge. The craftsman's skill lies in his/her capacity to move within this space and to let knowledge grow while moving within it.
