基于SD模型的装配式建筑供应链脆弱性研究

装配式建筑供应链的运作存在很多不确定性。为提高供应链管理效率，促进建筑业的发展，运用供应链运作参考(SCOR)模型对装配式建筑供应链脆弱因子进行识别，将装配式供应链系统划分为6个子系统；通过系统动力学（SD）模型对供应链脆弱性进行仿真。结果表明，装配制造流程是脆弱性最大的子系统，整个供应链的脆弱性随着建筑项目的推进而增大。     

Unfolding China’s state-owned corporate empires and mitigating agency hazards: Effects of foreign investments and innovativeness

Integrating agency and institutional perspectives, we describe how China’s socio-political institutions create state-owned corporate empires with unique agency conflicts. We develop a framework demonstrating how economically unjustified firm expansion, i.e. empire building, mediates the relationship between state ownership and performance. We uncover the instrument in empire building and appropriate corporate governance and strategic management remedies. An empirical study on 29,638 Chinese firms evidences that (1) increased state ownership drives higher management expenses and lower firm profitability though empire building; (2) long-term debt is used to finance empire building; and (3) foreign capital investments and innovativeness can mitigate these agency conflicts.     

Supplier Development Practices for Sustainability: A Multi‐Stakeholder Perspective

Supplier development for sustainability is a critical element of sustainable supply chain management and requires extensive multi‐stakeholder collaboration. This article establishes a conceptual four‐stage framework to analyse the collaborative mechanisms of supplier development practices, and presents an exploratory, qualitative analysis to identify the major contributors of sustainable supplier development practices, such as NGOs, industrial associations, consulting firms etc. Based on semi‐structured interviews about 63 organizations from different regions and industries, this article identifies three types of contributor: drivers, facilitators and inspectors. Instead of traditional stakeholder engagement processes, these contributors actively collaborate with buying firms and suppliers to design, implement and evaluate sustainable supplier development programs. The article then provides a matrix to describe the supply chain coverage and supplier performance of supplier development practices, given the absence or positive involvement of facilitators and inspectors. We conclude our study by suggesting future research directions as well as discussing managerial implications. Copyright © 2017 John Wiley & Sons, Ltd and ERP Environment

The evolving 5G case study in United States unilateral spectrum planning and policy

This paper tracks increasingly aggressive initiatives by the United States government to reallocate spectrum on an expedited and unilateral basis well before conclusion of inter-governmental coordination. Rather than embrace the customary commitment to achieve consensus on global spectrum allocations at the International Telecommunication Union (“ITU”), the Federal Communications Commission (“FCC”) has auctioned off large blocks of frequencies for the next generation (“5G”) of wireless services.The FCC might have framed its first 5G auction, reassigning Ultra High Frequency (“UHF”) spectrum, as a one-time deviation from compliance with long standing, intergovernmental coordination procedures. These frequencies have ideal signal propagation characteristics and the Commission could use financial incentives—unavailable in most nations—to expedite “repacking” by incumbent broadcasters willing to move, share or abandon spectrum in exchange for ample financial compensation. However, the FCC has continued to auction off 5G spectrum on grounds that it must find ways to abate an acute shortage of wireless bandwidth and doing so will regain or maintain global leadership in wireless technologies. This paper offers a critical rebuke to unilateral spectrum management, because the short-term benefits expected by the U. S. government likely will be offset by countervailing harms to 5G manufacturers, carriers and consumers. The paper tracks fractious preparation for the ITU's 2019 World Radio Conference by the U.S. delegation and the mixed record achieved there. Additionally, the paper explains how injecting trade, industrial policy and national security issues at the ITU can trigger more delays and disputes, including possible retaliation by nations displeased with U.S. efforts to subvert traditional technology optimization goals.A worst case scenario has the ITU deadlocked and unable to reach closure on “mission critical” spectrum planning issues at World Radio Conferences, convened every four years. The paper concludes that costs and likely challenges to the efficacy and legitimacy of the ITU will reduce the benefits accruing from the FCC's unilateral, spectrum planning campaign.

土木工程房屋建筑施工管理问题与策略评价

土木工程房屋建筑一直以来是建筑行业的一大重点,其中施工管理的具体落实对整个工程的质量起着决定性的作用。随着人们生活水平的不断提升,土木工程房屋建筑也在持续地发展。一旦施工管理环节出现问题,在降低工程质量的同时还会危及人员的生命安全。因此,论文通过对当前土木工程房屋建筑施工管理存在的问题进行简要的分析,综合当前建筑工程发展的局势,提出针对性的整改建议。     

房屋土建工程质量监督管理问题与强化建议探究

随着社会经济的快速发展,我国的房屋建筑工程也随之发展起来。建筑施工中无论是技术还是人员的配置都日趋合理,但同时一些问题也逐渐显现出来,如工程施工人员的素质水平不高、建筑市场混乱等,使得工程质量受到了影响,所以我们必须要加强对房屋土建工程的质量监管。     

The interaction between reputation and information search: Evidence of information avoidance and confirmation bias

This paper investigates how the valence of reputation affects the information search, and how the outcome of the search can result in a reevaluation of reputation. The protocol uses a digital version of the Information Display Board (IDB) to examine the dynamics of information search and reputation building. A sample of 1811 respondents was asked about their perceptions of the reputation of specific performing arts events, pre- and post-information search. The findings provide evidence of a confirmation bias (between positive information and the information search), and support information avoidance theories. Specifically, our results show that prior reputation only affected the online information search for consumers with no opinion, or with a positive opinion of a show's reputation. Furthermore, the information search only modifies reputation when consumers have no prior opinion.
