University–Industry Collaboration (UIC) has been identified as an essential item on Malaysia’s agenda for transforming itself into knowledge and innovation-based economy. However, despite the efforts, most initiatives have had limited results. This paper reports on an explorative study that sought to understand the contemporary realities of UIC in the Malaysian context. In particular, the study identified the expectations and impediments to UIC, from the perspectives of three groups of stakeholders – the academics, the industry players and policymakers. The findings reveal a number of barriers, including cultural differences, perceived lack of academic expertise and reputation, an inadequacy of institutional policies and regulations, lack of trust, issues of intellectual property rights, and the lack of an appropriate reward system. This paper concludes by proposing policy recommendations and strategies that could be used by the government, university, and the industry to promote further and foster university-industry collaborative opportunities and initiatives. 相似文献

中国劳动力市场运行轨迹及其发展障碍分析 总被引:1,自引:0,他引:1
在中国长达 40年之久的传统就业制度中 ,基本上不存在一般意义上的劳动力市场。单一就业格局的突破始于 2 0世纪 80年代初政府推出的“三结合”就业方针 ,而劳动力市场的形成则以国有企业中劳动合同制的推行 ,进而“再就业工程”的实施为标志。初步确立后的劳动力市场虽取得一定成就 ,但其发育并不平衡 ,并且市场自身的缺陷、市场供求主体的不明晰、工资调节机制不健全以及相关法律基础的不充分也在制约劳动力市场的进一步发育和完善 ,需要借助政府行为 ,通过深化改革 ,推进劳动力市场化进程 相似文献

AbstractWe identified 48 barriers to teaching environmental education reported by teachers in global literature and compared frequency to empirical data we collected from rural Ecuador, part of an understudied region and continent. We utilized Q methodology and interviews with 25 (78%) teachers at 6 schools to identify and categorize barriers. Perceptions of barriers ranked by Ecuadorian teachers were statistically classified into three factors: logistical (associated with fieldtrips, time, and money); training and lack of government support; and attitudinal (associated with student disinterest). In contrast, barriers related to student testing and controversial topics were only reported in more developed countries. Results enable region-specific recommendations. 相似文献

The governance of sustainable socio-technical transitions 总被引:8,自引:2,他引:8
A quasi-evolutionary model of socio-technical transitions is described in which regimes face selection pressures continuously. Differentiated transition contexts determine the form and direction of regime change in response to these pressures. The articulation of pressures, and the degree to which responses are coordinated and based on resources available within the regime, define the transition context. Four alternative contexts are described: endogenous renewal; re-orientation of trajectories; emergent transformation and purposive transitions. Agency and power in the governance of regime transformation are analysed. Power to affect change depends on regime membership, the distribution of resources for change and expectations. 相似文献

We used content analysis to analyze 42 counseling doctoral students' reports of supports and barriers influencing their researcher development across 3 years. In line with social cognitive career theory, the students named cognitive-person, environmental, and social-context influences. Analyses indicated no differences in frequencies of supports and barriers across time but significant differences by cohort. 相似文献
