Formal business process engineering based on graph grammars

Designing and managing a company's specific landscape and its business processes has been identified as a great challenge for several years. Business processes are highly dynamic and distributed and can only rarely be planned, modeled and analyzed completely. For a computer-aided business process system, which supports the designing and managing process, first of all a powerful uniform formalism is necessary, where all necessary knowledge concerning company's and its processes can be represented. In this paper we will concentrate on the introduction of such a formal methodology to describe business processes, company organization structures and information technology structures in one uniform formalism. The ideas we use are mainly based on methods from graph grammars, process management, Artificial Intelligence and business process (re)engineering.     

管理创新与经营者人力资本

管理创新是企业创新体系中一个重要的组成部分,管理创新的主体是企业经营者,因此企业经营者的人力资本状况与企业管理创新关系十分密切。本文论述了管理创新在企业创新体系中的地位与作用,对管理创新与经营者人力资本之间的关系问题进行了探讨,论述了管理创新与经营者人力资本提高之间的内在联系。

股东派生诉讼制度的完善初探——香港法院法定衍生诉讼案例分析

通过对股东派生诉讼制度的法律规定进行对比研究,本文认为香港法定衍生诉讼某些方面的制度设计可资我们予以借鉴。在公司治理机构不积极处理公司涉及的诉讼时,应允许股东代表公司介入诉讼。应增设法院听证程序,给予公司治理机构申辩的机会,平衡各方利益。当公司两名以上股东基于同一事实提出相冲突的诉讼请求以及公司治理机构对股东派生诉讼提出异议的时候,启动法院听证程序。     

国有企业经营者薪酬激励效应的实证研究

薪酬机制是国有企业改革中的难点问题,如何发挥薪酬作为国有企业经营者提升企业业绩的激励作用更是建立科学、公平的国有企业薪酬机制的焦点问题。文章通过对2005年～2006年国有上市公司的实证分析得到企业规模、净资产收益率、所在区域、国家股比例和经营者任期是国有企业经营者薪酬水平的决定因素,而独立董事和监事会并没有发挥应有作用。对薪酬激励效应实证的结果表明,国有企业经营者年薪和持股比例的激励效应较强,高管团队的薪酬差距也有助于企业业绩提升。

A tourist kit ‘made in Italy’: An ‘intelligent’ system for implementing new generation destination cards

This study investigates the advantages and the potentiality of the ‘tourist kit’, an Italian solution based on the concept of a prepaid card that is issued by a large postal operator. The destination card can be reloaded by tourists according to their needs and its validity is not restricted to short periods. Thus, the kit provides tourists with an integrated, practical, and flexible tool capable of making their stay more enjoyable as it allows cardholders to choose and buy many products and services at discounted prices. The kit creates customer loyalty by utilising smart technology aimed at collecting accurate tourist information. This model deserves attention because it is probably the world's first case of a large postal operator entering the tourism sector with the proposal of an integrated and advanced destination card scheme. This research also discusses interesting opportunities and challenges related to the implementation of new generation tourist cards.     

On the short-time behavior of the implied volatility for jump-diffusion models with stochastic volatility

In this paper we use Malliavin calculus techniques to obtain an expression for the short-time behavior of the at-the-money implied volatility skew for a generalization of the Bates model, where the volatility does not need to be a diffusion or a Markov process, as the examples in Sect. 7 show. This expression depends on the derivative of the volatility in the sense of Malliavin calculus. E. Alòs’ research is supported by grants MEC FEDER MTM 2006 06427 and SEJ2006-13537. J.A.

Reconciling Alternative Theories for the Safety of Owner–Operators

Motor carrier safety is an important concern of shippers, carriers, policy makers, consignees, insurance providers, and the motoring public. One aspect of carrier safety that has garnered substantial attention is whether carriers making greater use of owner–operators are more or less safe vis‐à‐vis carriers making greater use of employee drivers. Currently, conflicting theoretical predictions exist regarding the direction of this relationship. In this article, we offer a reconciliation of the alternative theoretical predictions by developing a coherent theory that merges sociological rational choice theory and theory regarding motor carrier safety. We subject our theory to empirical testing by fitting a series of seemingly unrelated regression models to a vector of safety measures tracked as part of the Federal Motor Carrier Safety Administration's Compliance, Safety, and Accountability program. Our results are consistent with our proposed theory of owner—operator safety and provide meaningful theoretical and managerial implications and directions for future research.
