Human resources in the mixed ownership reform of Chinese ports: the mediating effects of organizational commitment

In the process of the change to mixed ownership of Chinese ports, the allocation of human resources has become increasingly important because of the workforce’s growing concerns regarding losses of benefits. The mediating effect of organizational commitment in the relationship between person-organization fit and organizational citizenship behavior (OCB) can provide a significant reference for port managers and regulators, i.e., the government, regarding the framework of human resource systems. The data examined in this study were collected from three Chinese ports (Qingdao Port, Yantai Port and Rizhao Port) that are in the process of changing to mixed ownership. Structural equation modeling was applied to test the hypotheses. The results show that it is extremely difficult for groups with vested interests in Chinese ports to achieve consistency fit in the short term and to accept potential losses. Moreover, it is imperative to adopt a scientific and efficient person-organization fit mechanism and personnel system to achieve a higher level of fit.     

我国外资银行市场准入规则实证分析研究——兼评《外资银行管理条例》的合规性

根据入世承诺,我国从2006年12月11日起向外资全面开放金融业。作为规范外资银行的主要法规,新修订的《外资银行管理条例》及其实施细则对外资银行的本地注册、人民币零售业务和银行卡业务等方面作了相应的限制性规定。从法条层面看,这些限制规定似乎符合世贸组织有关服务贸易审慎监管的规定,但是从法理层面分析,特别是结合我国具体的入世承诺和其它的法律规定,这些限制措施的审慎理由并不充分,很容易受人诟病并招致其它世贸组织成员的挑战。     

Filling the gap between voters and cryptography in e-voting

Cryptography is an important tool in the design and implementation of e-voting schemes since it can provide verifiability, which is not provided in the traditional voting. But in the real life, most voters can neither understand the profound theory of cryptography nor perform the complicated cryptographic computation. An e-voting system is presented in this paper to leverage the use of cryptography. It combines the advantages of voting scheme of Moran-Naor and voting scheme based on homomorphic encryption. It makes use of the cryptographic technique, but it hides the details of cryptographic computation from voters. Compared with voting scheme of Moran-Naor, the new system has three advantages: the ballots can be recovered when the voting machine breaks down, the costly cut-and-choose zero-knowledge proofs for shuffling votes made by the voting machine are avoided and the partial tally result in each voting machine can be kept secret.

对船舶间“避碰协议”性质的分析

现通行的观点认为,船舶间通过VHF进行联系,达成了避让的“协议”,分为“协议避碰”和“协议背离”两种情况.在实践中,时有因两船间的这种“协议”而导致了碰撞事故的发生,在分析和归责的过程中形成了两种不同的观点,导致了碰撞责任分析和分摊的巨大争议.通过对这些争议的分析,将其归纳为“承诺履行说”和“规则至上说”.根据长期的航海实践和对碰撞事故处理的实践,就如何理解这种船舶间协调避让一致的意见的性质,这种避让行为的协调在归责中的地位和作用如何等,进行了分析,表达一些不同的观点,以期达到正确理解和履行这种船舶间协调的意向,真正起到避免碰撞的积极作用.     

The human talent and its role in ISM Code effectiveness and competitiveness in the shipping industry

The present study empirically evaluates the role of human talent in the effective implementation of quality management systems in the shipping industry context. Specifically, we analyze the relationships among top management commitment to quality, ISM (International Safety Management) Code effectiveness and competitiveness as well as we assess the influence of talent in these associations. We test our research hypotheses using a sample of 199 shipping companies located in Greece. The findings show that ISM Code effectiveness acts as a mediator between top management commitment and shipping company competitiveness, while the different talent philosophies were found to moderate this relationship.

由于需求的不确定性,托运人的承诺时间会对运输服务供应链的决策产生影响. 因此,本文考虑在延迟承诺和提前承诺两种承诺时间下,基于运价分别为外部定价和承运人定价两种情况,建立了运输服务供应链中承运人的运输价格和托运人的托运量优化决策模型,并分别对延迟承诺和提前承诺、整体决策和单独决策时的优化结果进行比较分析,从而为运输服务供应链决策提供有效的参考价值. 通过研究得出,整体决策时运输服务供应链的收益总是大于单独决策时的收益;承运人的运价也对托运人的承诺时间产生影响,在不同的运价下,提早承诺和延迟承诺的优越性不同.     

基于策略消费者的易逝品两阶段销售定价策略

在不确定需求下研究易逝品零售商面对具有异质性策略消费者的两阶段定价问题.考虑零售商两阶段定价是否采用提供保价险的价格承诺策略,分别构建了无价格承诺、在第1阶段和在第2阶段进行价格承诺的零售商收益模型.运用均衡理论和逆向归纳法分析了降价期价格、购买均衡和全价期价格的收益情形,研究结果表明:在这几种情况下,采用价格承诺策略...
