农药污染场地修复亟须加快   总被引:3,自引:0,他引:3  
我国是农药生产和使用大国。从20世纪50年代开始生产,至今已有约60年历史。我国农药生产量大,而危害较大的有机氯农药一度曾达到总产量的80%以上,其中六六六和滴滴涕总产量分别达490万吨和46万吨。农药污染场地底数不清截至2010年,农业部药检所《农药登记报告》上记录的企业数高达4100多家,远多于经国家发改委核实或质检总局发放许可证的企业数量。我国农药生产工艺比较落后,技术管理水平低下,缺少必要的防控措施,生产过程中的滴漏现象比较严重。  相似文献

产业技术选择与产业技术生态环境的耦合效应分析   总被引:5,自引:0,他引:5  
技术选择问题是技术经济学研究的核心问题。技术选择在技术转移、技术扩散与技术变迁过程中起着重要作用。是发展中国家技术能力发展的首要阶段。本文从生态学角度,系统分析了产业技术选择与技术生态环境耦合效应,并以吉林省37个工业产业研究对象进行了实证研究。实证结果显示,吉林省工业产业中技术选择与技术生态环境之间不匹配现象普遍存在,超过80%产业耦合效应处于失调状态,并且产业规模是制约产业选择技术水平的约束因素。  相似文献

The literature on flexible work practices has not yet evaluated in detail how the characteristics of a job affect job satisfaction. This study makes a distinction between two types of flexible work practices according to their aims: the accommodation of employees’ personal lives (employment practice) and the operational reasons of a firm (work practice). Based on this distinction, we studied how the characteristics of a job, which reflect the use of ICT to support the spatial disaggregation of business processes, influence the relationship between the two types of flexible work practices and job satisfaction. We show, through a survey conducted on 987 workers, that the characteristics of a job that favour work disaggregation positively moderate the influence of flexible work as a work practice on job satisfaction, but they do not moderate the influence of flexible work as an employment practice. The implications for managers, workers and scholars are discussed.  相似文献

Despite research suggesting certain death of blue-collar work due to technological advancements, blue-collar jobs continue to be in demand. Through a study of the blue-collar dominant Transport and Logistics sector in Australia, we apply a Critical Realist framework to consider the tendencies contributing to, and limiting, technological uptake and worker displacement. Our analysis of interviews with sector managers demonstrate how technological uptake decisions to enact labour saving technologies are often constrained by other causal mechanisms and associated (counter) tendencies. Causal mechanisms related to geographical artifacts, industry structure and established business models, along with class structure, mitigate against ‘big bang’ technological transformation and the demise of blue-collar work. We conclude that tracking the future of work is important, but it cannot be done solely on the basis of technological capacities to displace labour or without consideration of the complex interplay of causal mechanisms and tendencies shaping employer decisions about technology.  相似文献

We examine the contingent impact of implementing an enterprise‐wide information technology system (Enterprise Resource Planning) on perceptions of work complexity in clerical, technical and managerial service sector jobs. Using matched and control samples of employee survey data, we compare pre‐ and post‐intervention perceptions of work complexity and importance of analytical skills across three hierarchical job levels: clerical, technical and managerial. We find that employees in clerical jobs, at the lowest level in the hierarchy, experience a significant increase in work complexity and need for analytical skills, whereas those in technical and managerial service jobs do not. Implications for theory, management of technology and employment policy are discussed.  相似文献

This introduction sets out the context for the Special Issue and offers an in-depth reflection on key themes addressed by our contributors. The Special Issue aims to place the social relations of production at the centre of debates about technology and the future of work, and create space for greater critical reflection on what it means to go ‘beyond technological determinism’. We identify ways in which aspects of technological determinism continue to influence debates on technology, the labour process and industrial relations, despite efforts to reject it. We argue that this influence is manifested in some persistent problems within the literature including overly rigid periodisations (such as ‘platform capitalism’), a narrow conceptual repertoire (which reifies notions like ‘algorithmic control’) and a constricted empirical focus. We elucidate the value of a social shaping of technology (SST) approach to overcome these challenges and provide a brief overview of the articles contained within the issue.  相似文献

汽车产业是一个传统行业。以互联网为代表的信息技术产业的发展,以及谷歌、苹果等科技巨头开始对汽车产业的涉足,为汽车产业的发展提供了全新的机会,这使得信息技术产业与汽车产业呈现了耦合的态势。尽管在制造、售后等环节我国汽车制造企业与国外汽车制造企业的差距正在逐年缩小,但是在产品开发、智能制造等环节,依然是目前我国汽车企业最为薄弱的环节。按照产业耦合理论,我们将两个产业的耦合程度,按照由弱到强的关系,分为无耦合、低度耦合、中度耦合、高度耦合四个阶段,本文将通过信息技术产业与汽车产业的数据,对二者的耦合程度、可持续发展性进行全面研究,以便达到为我国汽车产业与信息技术产业的耦合找到可行路径的目标。  相似文献

This paper outlines a selection of technological and organisational developments in the information and communication technology (ICT) sector and analyses their likely challenges for workers and trade unions around the globe. It addresses the convergence of telecommunications and information technology, the related developments of ubiquitous computing, ‘clouds’ and ‘big data’, and the possibilities of crowdsourcing and relates these technologies to the last decades' patterns of value chain restructuring. The paper is based on desk research of European and international sources, on sector analyses and technology forecasts by, for instance, the European Union and Organisation for Economic Co‐operation and Development, and some national actors. These prognoses are analysed through the lens of recent research into ICT working environments and ICT value chains, identifying upcoming and ongoing challenges for both workers and unions, and outlining possible research perspectives.  相似文献

This study discusses how professionalism and work ethics influence how health care professionals work around new technologies. When people avoid using technologies, they are not necessarily ceasing to engage in their work activities. The workaround strategies presented here are rather practical expressions of professionals’ active encounter with the complexity of work situations, and can therefore be important signs of professional ethical judgement. Drawing on science and technology studies and the concept of invisible work, the study discusses workaround situations that arise in health care work in Denmark. The aim and contribution of the study is twofold. First, it attempts to revitalise the discussion on technology workaround strategies as responsible professionalism. Second, it will direct attention to and contribute to an understanding of how the normativity embedded in technological development in the health care sector is central to the work of health care professionals.  相似文献
