过程视角下高校实验教学质量调查研究——以N大学为例

实验教学质量高低直接影响高校人才培养的质量及层次,科学的实验教学管理模式有利于提高实验教学质量。从实验教学过程的视角,以N大学812名学生和92名教师为调查对象,就实验教学准备、实施、考核与评价三个过程的教学质量状况进行问卷调查的结果显示,师生对实验教学过程质量的总体评价较高,但对实验设备配置、实验室开放程度、实验项目数量与层次、实验教学考核等过程因素评价指标较低,故高校需进一步加强实验教学过程的质量控制,不断提高实验教学管理水平。

Green multi-tier supply chain management: An enabler investigation

Stakeholder pressure, from actors including regulators, consumers and non-governmental organizations, has made organizations more responsible for poor environmental performance of their direct and sub-suppliers. Thus, green multi-tier supplier management (GMSM) has become an emergent topic. Yet it is still unclear how to enable GMSM practices effectively, i.e. how to enable sub-suppliers' environmental performance improvement. To help address the gap in the literature, this paper aims to identify enablers for sub-suppliers' environmental performance improvement, and it further applies a Decision-Making Trial and Evaluation Laboratory (DEMATEL)-based case study method to evaluate inter-relationships among these enablers and improve the focal company's GMSM practices, by using action research (AR) method principles. The data analysis and discussion with a follow-up evaluation after two years provided insights for the successful implementation of GMSM. The results show that top managers’ support from the organizations is a prominent and necessary foundational enabler. An interesting observation is that close proximity of supply chain members is regarded as a very prominent enabler. Evaluation and feedback on these enablers two years later found that the enabler mapping was beneficial, allowing them to address the most influential enablers, and thus the GMSM practices of the focal company has been highly improved. This paper concludes with directions for further research.     

Using Laboratory Experiments in Logistics and Supply Chain Research

Laboratory experiments provide an underutilized methodology for subjecting research in logistics and supply chain management to rigorous scientific scrutiny. As discussed in this paper, by following established procedures researchers can create an economic system in which behavior can be observed and replicated. With the ability to control the institution and the environment, researchers have complete information and can exogenously manipulate treatment variables, neither of which may be feasible in field work. We also address many of the reservations that skeptics of laboratory experiments often express including issues of realism, participant sophistication, and payoff stakes. We then provide several examples where experiments have been used to study issues relevant to logistics and supply chain management including auctions, wholesale practices in gasoline markets, inventory replenishment, liberalization of the electric power industry, and deregulation of the natural gas markets. Finally, we identify several additional areas where laboratory experiments could be informative.

An analysis of information overload with implications for survey design research

Abstract

A laboratory‐type experiment was conducted to examine potential information overload causes and solutions. It was found that both information quantity and information complexity are potential causes of information overload. The experiment results also suggested that information overload problems may be reduced through carefully designed information display patterns. When designing survey questionnaires, attention must be given to potential causes of information overload. Methods of presenting information that ameliorate information overload must also be considered. As demonstrated in this study, survey designs can be tested in controlled, laboratory‐type experiments. The results of these experiments can then be used to improve the design of field survey questionnaires.     

Managerial Commitment to Sustainable Supply Chain Management Projects

Most companies are under pressure to improve the environmental sustainability of their supply chains. However, there is considerable variance in companies' ability to successfully deploy environmental management projects. One important factor, according to articles in the academic and business press, is the ability of champions of sustainable supply chain management (SCM) projects within organizations to gain the commitment of colleagues (e.g., other managers from a variety of functions) to help these projects succeed. Therefore, this paper examines variables that affect a project champion's ability to gain this commitment from colleagues. In particular, building on existing research, this research employs a video‐based experimental design to examine the effect of the influence approach that the project champion employs, the values of the person the champion is trying to influence, and the organizational climate. The results suggest that organizational climate and certain individual values directly affect commitment. There are also interactions between values and influence tactics. The research adds to the field's growing knowledge on the antecedents of sustainable SCM within companies while providing valuable guidance for environmental champions and for top managers.
