An analysis of institutional pressures,green supply chain management,and green performance in the container shipping context

This paper presents a study which utilized a conceptual framework with institutional theory as its base to empirically evaluate the impact of institutional pressures, internal green practices, and external green collaborations on green performance. Factor analysis was employed to identify the key institutional pressures (i.e. coercive, normative and mimetic pressures), internal green practices (i.e. green shipping practices and green operations), external green collaborations (i.e. green collaboration with supplier, green collaboration with partner, and green collaboration with customer), and green performance (i.e. reduction of pollutants, and perceived green brand) dimensions. We collected data from surveyees employed by 129 container shipping companies and agencies in Taiwan, and applied a structural equation model (SEM) to test the research hypotheses. The findings revealed that institutional pressures have positive effects on internal green practices; internal green practices positively influence external green collaborations; internal green practices and external green collaborations positively influence green performance but institutional pressure is not positively associated with external green collaborations. Theoretical contributions and managerial implications are presented to help container shipping operators improve green performance.     

高铁运用安全的三大技术局限性

从当前高铁运用问题来看,高速转向架存在三大非线性,即拖车构架点头迟滞非线性、抗蛇行动态刚度非线性和非线性稳定性.在充分认识上述三大非线性的基础上,应用抗蛇行频带吸能新理论,提出了最佳安全稳定裕度调控技术对策,以进一步协调高铁运用安全性与经济性之间的矛盾.在“重返”350 km/h高铁运营的技术准备中,应当对如下三大技术局限性给予充分重视,即商业运营速度、振动疲劳和曲线横风,特别是曲线横风应当作为一项当前十分急迫的计算流体动力学CFD科研任务.     

On a clear day in Ogunquit,Maine

Abstract

Winning a court case against a federal agency may seem to be the sweetest success for an environmental group, but losing litigation is not total failure. In the case of Ogunquit Village Corporation et al., vs. R. M. Davis the plaintiff lost the legal skirmish against the Soil Conservation Service, but in doing so significantly aided the struggle within the agency to implement more environmentally sensitive planning and engineering procedures. This paper describes the court case in terms of the Soil Conservation Service's procedural and policy responses including the agency's modus operandi and the internal paths/pitfalls involved with the implementation of visual resource management. The author also speculates as to the visual resource understanding of the evidence presented by the plaintiff and a possible but unstated visual basis for the original complaint.     

Transferability of sustainable urban mobility measures

This paper describes an approach developed to identify common elements of city performance that have transferability potential across a number of cities. The findings provide a wealth of information sourced from 200 measures in 19 European cities. A transferability framework is proposed, that uses ideas from traditional top-down approaches using city clustering to infer the transferability of measures, as well as elements of a bottom-up approach, based on the concept of “measure enabling context”. Systems' thinking diagramming was used to depict relationships between measures, drivers and barriers, portraying the feedbacks at work and the cause-effect relationships, to establish appealing preconditions for transferability.     

Developing sustainable transport for the next generation: The need for a multi-sector approach

While some countries have made progress in encouraging more sustainable transport and travel patterns, there are limits as to how far this can be taken simply by looking at the decarbonisation of transport systems, since most travel is a derived demand and hence is strongly influenced by decisions taken by public and private sector agencies in different sectors. The paper first identifies some of the major non-transport sector influences on different aspects of travel behaviour. It then looks in more detail at changing patterns of grocery shopping over the last half century, and how these changes have been associated with new non-transport technologies and accompanying developments in business and social practices. Next, a simple visual spreadsheet tool is presented, that has been used by agencies to explore the main cross sector impacts (both positive and negative) of their major location and operating decisions. Finally, the paper proposes three ways in which cross sector synergies can be encouraged: (i) by giving each sector or major organisation responsibility for all CO₂ emissions associated with its activities, including those generated by the travel of its staff, customers, suppliers, etc.; (ii) by making major policy making within government a cross sector activity; and (iii) by developing a common, cross sector appraisal methodology for assessing the full range of impacts of policy proposals.     

Regulating the regulator: The impact of professional procuring bodies on local public transport policy and its effectiveness

During the past 15 years competitive tenders have become a common procedure when procuring local bus services in Europe. In particular, tenders with gross cost contracts and the so-called Scandinavian model have gained popularity, resulting in a vast amount of research on optimal contractual relationships between government and operators. This paper pays attention to a rather neglected part of the Scandinavian model: the construction of professional procuring bodies and their relationship to the local public administration, focusing on its implications for policy steering and service performance.The paper outlines briefly two different perspectives of analyses of organisational models: one perspective is anchored in principal-agent theory and institutional economics; and the other perspective in political science. Empirically, the article is based on an evaluation of the relation between two Norwegian counties and the administrative company responsible for planning and procuring public transport services. This evaluation indicates, firstly, important common challenges for the county administration due to lack of regional administrative competencies in relation to the administrative company, which also hampers the county’s role as coordinator of policy areas of importance for public transport. Secondly, due to increased transaction costs, the establishment of administrative companies does not seem compatible with contracts relying on net cost solutions with huge scope for operator initiatives.     

Aligning the purchase of green logistics practices between shippers and logistics service providers

This paper explores shippers’ (i.e. logistics buyers) and logistics service providers’ (LSPs) perceptions of green concerns under diverse contractual settings during the key phases of the logistics purchasing process: request for proposal, negotiations, contracting and execution. Accordingly, it derives recommendations that could increase the actors’ inter- and- intra-organisational alignment on green targets throughout these phases. Empirical data are obtained from eight individual cases of three shippers and five LSPs, representing the buyer/seller roles within logistics arrangements. Contrary to previous literature holding the view that setting more green demands by shippers would guarantee green outcomes, the findings show that shippers’ green demands may hinder green logistics applications due to impediments to LSPs’ asset-sharing strategies. Also, a deadlock situation is revealed in the negotiations phase, where both actors await each other to introduce additional demands/offers—calling for further regulatory intervention to release this deadlock. Moreover, this paper shows how a mismatch of interests in contractual periods between shippers and LSPs can obstruct green investments—signalling that the green criterion is not the decisive factor in shaping shippers’ outsourcing strategies. The findings also stress a lack of follow-up efforts by shippers on green measures that were specified pre-contract, attributing this to contrasting intra-organisational objectives within shippers’ firms. This paper contributes to the green logistics purchasing literature by revealing how different contractual settings play an important role in shaping shippers’/LSPs’ perceptions of green concerns during the logistics purchasing process. Further, it is one of the first studies to provide phase-specific recommendations to increase the actors’ alignment on green targets.
