Introducing a preliminary consists selection in the locomotive assignment problem

The Locomotive Assignment Problem (LAP) is a class of planning and scheduling problems solved by assigning a fleet of locomotives to a network of trains. In the planning versions of the LAP, the type of consist (a group of linked locomotives) assigned to each train in a given schedule is determined. We introduce an optimization model (called consists selection) that precedes the planning LAP solution and determines the set of consist types. This selection leads to solutions that are characterized by potential savings in terms of overall fueling cost and are easier to handle in the routing phase.     

Psychological Capital: Impacts on Asset Management

Drawing together the areas of behavioral finance and positive psychology, the present research sought to investigate whether the psychological capital of investment fund managers is associated with fund performance in a context of financial instability. The theoretical propositions were presented and evaluated empirically through primary data on investment fund manager profiles and secondary data on the cumulative stock fund returns. The results indicate that funds managed by managers with greater resilience and optimism obtained a higher return than the mean profitability in a period of market instability.     

CENTRAL AND EAST EUROPEAN TRADE ORIENTATION AND FDI FLOWS: PREPARATION FOR EU MEMBERSHIP

At the June 1997 Amsterdam Intergovernmental Conference (IGC) the heads of state of the 15 European Union (EU) nations decided to expand to the East. At the Luxembourg IGC in December 1997, they invited the Czech Republic, Hungary, Poland, Estonia, and Solvenia from Central and East Europe (CEE) and Cyprus from the Mediterranean region to begin admission talks in early 1998. Efficient involvement in international trade and the division of labor through foreign direct investment (FDI) are two of the most important prerequisites to economic transformation, modernization, and sustained economic growth. Thus, trade reorientation by the CEE nations from the former Council for Mutual Economic Assistance (CMEA) region to the OECD region in general and the EU in particu lar, as well as the volume and nature of inbound FDI are among the most reliable indicators of these countries' abilities to meet the EU admission standards. Trade reorientation by the CEE nations and FDI inflows between 1990 1995 have established a sound basis for effective economic transformation and modernization. It has also increased the ability of selected industries to compete in the EU Single Market. By 1997 the CEE nations were in a good position to generate sustained economic growth and to gradually meet the EU admission requirements.     

Direct and representative participation in Europe: recent survey evidence

Despite the wealth of literature on HRM and employee involvement, now there has been a remarkable lack of large-scale survey evidence on the diffusion employee involvement in work organizations in Europe. This gap in large-scale survey evidence on the diffusion of direct employee participation has now been filled representative sample of workplaces in ten major European Union countries which commissioned by the European Foundation for the Improvement of Living and Working Conditions in Dublin (the EPOC project). It is by far the most comprehensive overview of the implementation and effects of direct employee participation of its kind. The paper shows that, on the basis of the EPOC survey results, there appears to considerable gap between the rhetoric and reality of direct participation. The paper shows that while the incidence of different forms of direct participation was widespread ten countries, the scope, in terms of number of issues involved and the number of given to employees, was relatively limited for most direct participation forms. The survey also showed that the introduction of direct participation posed little threat to trade representatives. Indeed, works councils and union representatives were in most 'agents of change' rather than barriers to the development of the more intensive practice of direct participation.     

Direct democracy: obstacle to reform?

Swiss direct democracy is often accused of being an obstacle to reforms, with the strong influence of interest groups being the reason. Actually, the referendum has a retarding effect: it implies a status quo bias. On the other hand, the initiative has an accelerating effect. The influence of interest groups is hardly larger in direct compared to representative democratic systems. Thus, it is highly questionable whether the abolition of Switzerland’s direct democracy (at the federal level) would—in the long-run—really lead to political decisions which are more open to reforms.     

Accrual accounting does not necessarily mean accrual accounting: Factors that counteract compliance with accounting standards in Swedish municipal accounting

The regulation of Swedish municipal accounting has undergone fundamental changes over recent decades. Municipal accounting became regulated by law the 1st of January, 1998 after having been merely voluntarily regulated in the past. In accordance with the legislation, a standard-setting body was formed, with responsibility for development and interpretation of generally accepted accounting principles for municipal accounting. Important aims of the legislation and reform were to suppress ‘creative’ accounting and to increase the level of harmonization and comparability. Using the lens of positive accounting theory as well as institutional theory, this paper describes and explains the impact of the legislation and standard setting in the Swedish municipal sector. We have used a triangulation approach, collecting data through a survey, documentary study and interviews. The overall results show that the reform has had a very limited impact on accounting practice. Compliance with accounting standards was in general poor. This result is in line with the assumptions of positive accounting theory. However, the study also shows that there are differences among the preparers which can be explained by institutional theory. Large municipalities produce better accounting information (i.e. more in line with generally accepted accounting principles) than the municipalities in general. Weak audit quality seems to be another important factor that explains the poor compliance with accounting standards.

日本服务业对华直接投资的决定因素分析——基于母国和东道国的双向考虑

本文借助计量经济模型,对1995-2005年日本服务业对华FDI的决定因素进行经验分析。修正后的模型显示,日本服务业对华FDI主要受中国的市场规模、中国对日本市场的开放程度以及中国服务业增量三个变量所决定。服务业早期的对外投资行为有跟随本国客户的模式,但是本文显示1995以后的日本服务业对华投资已基本摆脱跟随客户的模式。
