Toward Closing the Loop between Infrastructure Investments and Societal and Economic Impacts

The long-term value proposition of transportation infrastructure investments can be significantly distorted if the short-term effects of spatial externalities on land use patterns, economic expansions, and migration patterns are not properly included in the analysis. Some of these effects occur over a short period of time and soon after the investment materializes, whereas others take longer and follow more steady patterns. In this article, we develop a novel dynamical model of a primal society with constructs that are specifically geared toward transportation infrastructure expansions and investments. The model quantifies the impact of these expansions on some key performance indicators and on the overall utility and production capacity of the society. We argue that traditional analytical models that work on the premises of stationary behavior and a static response of society to changes in infrastructure do not correctly capture these effects. The land use patterns and spatial expansion computed from the model are validated against existing theory on land use. Preliminary results on how to use the model for value proposition analysis are also presented using simple case studies.     

Could HRM support organizational innovation?

Nowadays, it has become clear that the capacity of organizations to innovate and manage their human resources can be sources of competitive advantage. Recently, literature also asserts a positive relationship between human resource management and innovation. However, very little empirical research has specifically addressed those relationships. Using structural equations modelling with data collected from 173 Spanish firms, this study analyses them. Our findings show that innovation contributes positively to business performance and that human resource management enhances innovation. Implications for both academics and managers as well as future research lines are discussed.

Who bribes in public contracting and why: worldwide evidence from firms

We study procurement bribery utilizing survey data from 11,000 enterprises in 125 countries. About one-third of managers report that firms like theirs bribe to secure a public contract, paying about 8 % of the contract value. Econometric estimations suggest that national governance factors, such as democratic accountability, press freedom, and rule of law, are associated with lower bribery. Larger and foreign-owned firms are less likely to bribe than smaller domestic ones. But among bribers, foreign and domestic firms pay similar amounts. Multinational firms appear sensitive to reputational risks in their home countries, but partially adapt to their host country environments.     

能力本位的项目化改造之高职商务英语教学改革探索

由于社会对外语人才的需求呈多元化趋势,过去那种单一外语专业和基础技能型的人才已不能适应市场经济的需求。必须通过教学改革以实现商务英语人才培养质量的提高,而能力本位的教育为此指明了方向,项目化改造为此提供了一种实现的途径。     

Fairness,legal compliance,and organizational commitment

Attribution theory is used to hypothesize a positive relationship between one's perception that a fairness motive underlies personnel/human resource management activities and one's organizational commitment. The hypothesis is tested via a survey of 48 operating managers in a Midwestern department store chain. Using hierarchical regression to control for job satisfaction and length of service, a significant positive relationship exists between commitment and the perception that a fairness motive underlies personnel/human resource management activities. Commitment is not significantly related to the perception that a legal compliance motive underlies the activities.

The mean residual of record values at the level of previous records

In the study of reliability of the technical systems, records model plays an important role. Suppose that a technical system is subject to shocks, e.g. peaks of voltages or stresses. The successive large shocks may be viewed as realizations of records from a sequence of identically independent voltages. Assume that the lower limit value of the mth record voltage (stress) is v > 0. Under these conditions, we propose a mean residual of records (MRR’s) for the future records. We study several properties of MRR. We show that the proposed MRR uniquely characterizes the distribution function that generated the sequence of records. It is proved that when the model under study has an increasing hazard rate the corresponding MRR is decreasing. We also compare between two record systems based on their MRR’s when these systems are ordered in terms of their hazard rates.     

社会保障税的税制思考

开征社会保障税势在必行。作为筹集社会保险资金的主要途径,社会保障税具有强制性和固定性,在社会、经济发展过程中起着特殊的作用。社会保障税的设计要充分考虑劳动者和政府的利益。结合一些国际经验和我国的实际情况,对符合我国国情的社会保障税制基本框架作一些研究和探索。
