Prioritization of applicable drivers for green supply chain management implementation toward sustainability in Thailand

ABSTRACT

It is essential that the green supply chain management (GSCM) implementation is effectively supported by several strategic drivers for successful implementation and sustainability, especially for the ‘green’ start-ups with a sustainability-driven organizational strategy. This study aims to determine and prioritize the applicable drivers for GSCM implementation of sustainable development strategies in the electronics industry in Thailand. The applicable drivers and their priorities are obtained by applying the fuzzy group decision-making approaches including fuzzy Delphi and fuzzy Analytic Hierarchy Process, based on Thai experts’ perspectives. In this study, three prominent organizational theories, resource-based view, relational view, and institutional theory, are needed to explain the drivers of sustainability and to develop a hierarchical model for prioritization of the drivers. Finally, based on the findings of this study, several recommendations are made that may help to improve the sustainable development in Thailand through more effective implementation of GSCM.     

基于粗糙集理论的路段交通事故多发点成因分析

交通事故多为多种原因综合造成且具有不确定性。判别各因素对于引发交通事故的影响程度存在困难,因此,需要引入不确定性分析方法。基于粗糙集理论具有处理不精确、不确定与不完全数据的优势,是一种先进的并处于不断发展的不确定性分析和推理方法。笔者提出路段上交通事故成因分析的模型和方法。具体做法是,根据该路段事故多发点的统计数据建立基于粗糙集理论的决策表,再利用粗糙集模型的简约算法求出各个因素的重要性,从而判断各因素对交通事故的影响程度大小,为决策提供依据。以算例说明模型和方法的可用性。     

The impact of government subsidy and tax policy on the competitive decision-making of remanufacturing supply chains

In this paper, we consider a two-period competition model of a remanufacturing supply chain consisting of three members: a new product manufacturer, a recycler and a remanufacturer. The manufacturer supplies new products in the first period and the remanufacturer participates in the competition in the second period. We consider three scenarios in the second period: (1) there is no government subsidy in the competition; (2) there is only government subsidy in the competition; (3) there are both government subsidy and tax in the competition. First, we give the optimal decision-making of the manufacturer, the remanufacturer and the government in the three scenarios; second, we analyse changes in the decision-making of the manufacturer and remanufacturer in the three scenarios and compare their results. We analyse the effects of government subsidy and tax and their asymmetric use on manufacturers’ and remanufacturers’ decision-making variables and competitive performance. We also take consumer awareness of environmental protection into account and examine its impact on subjects’ decisions. Lastly, we operate a numerical example to show the results.

Implementing wildlife-management strategies into road infrastructure in southern Ontario: a critical success factors approach

Wildlife-road conflict has profound negative impacts on both wildlife populations and society. Despite a long-held understanding of this problem, in most regions the wildlife-management strategies (WMS) available to mitigate this conflict are still relatively underutilized. This study examines the implementation of these strategies into road infrastructure, using Southern Ontario as a case study, in order to develop an understanding of what leads to successful WMS implementation. The project management concept of critical success factors was applied and interviews with project decision-makers and key stakeholders were conducted. Nine factors were identified and a comparison between a ‘smooth’ and ‘rough’ project is used to illustrate the cumulative effects that these factors, and their interrelationships, have on project implementation success. Practitioners can use these findings to evaluate WMS projects based on likelihood of success and allocate resources accordingly, ultimately leading to increased chances of implementation and overall benefit to conservation and society.     

不同营养环境下棕鞭藻共栖细菌的群落结构比较

微藻富含油脂,可以用作合成生物柴油的原料,被认为是最具发展前景的生物质能源.微藻的光合培养体系往往是非纯培养体系,现有研究更多地关注微藻生物量的积累及其对废水环境的净化效果,而对体系中广泛存在的共栖细菌缺乏全面深入的认知.本文通过对棕鞭藻共栖细菌的16S rDNA基因进行高通量测序分析,研究棕鞭藻（Ochromonas）在生活废水、BG11及Glu+BG11（BG11中添加10 g·L^-1葡萄糖）3种不同营养环境中共栖细菌的群落结构差异,进而阐明有机物及复杂废水环境对微藻共栖细菌群落结构的影响效果.结果表明,生活废水、BG11及Glu+BG11 3种营养环境中共栖细菌群落结构存在显著差异,生活废水体系中生物多样性显著高于BG11及Glu+BG11体系,生活废水中共栖细菌香浓（Shannon）多样性指数高达4.32,其次是BG11及Glu+BG11,Shannon指数分别为2.13、1.54.从共栖细菌群落的组成上看,3种营养环境中优势菌属差异显著,生活废水中优势菌属有芽殖杆菌属（Gemmobacter）、鞘脂单胞菌属（Sphingomonas）及玫瑰球菌属（Roseococcus）,相对丰度分别为14.46%、14.9%、14.54%,其中,芽殖杆菌属只在生活废水中有较高丰度.BG11中寡养单胞菌属（Stenotrophomonas）与玫瑰球菌属的丰度分别高达26.86%、51.03%.Glu+BG11中寡养单胞菌属较BG11中显著增加,达到82.41%,而玫瑰球菌属较生活废水及BG11中则明显降低,菌群丰度仅为6.2%.对比3种营养环境,玫瑰球菌属均具有较高丰度,是棕鞭藻良好的共生菌.

Linking Water Science to Policy: Results from a Series of National Workshops on Water

To ensure science better informs the decision-making process, researchers and policy/program managers need to understand and respect each other's way of working, culture and operational timelines. However, there is little practical guidance on how this should be done and even less documented experience with specific mechanisms that better link these two groups. The published literature on information transfer has largely emphasized the dissemination of standard packages of information to ill-defined constituencies whose needs for scientific information are not well understood. Environment Canada's National Water Research Institute, on behalf of the Canadian Council of Ministers of the Environment, led a series of “Linking Water Science to Policy Workshops” as one such mechanism by which recent science could be delivered to practitioners, and practitioners could identify their research needs to scientists and research managers. There is a pressing need to explore and share experiences using creative mechanisms for sustained dialogue and networking between scientists and policy and program managers. The lessons learned from the workshop series and the need for science to continually inform the decision-making process has particular relevance for Canada's Ecosystem Initiatives given their integrated, place-based focus on long-term restoration and protection, and the challenge of continually changing ecosystems.The Canadian Crown reserves the right to retain a non-exclusive, royalty free licence in and to any copyright.
