浅谈军地一体化物流体系的构建

在作战和后勤日益融合的今天,单纯由军队负责物资供应保障已经变得很不经济甚至不现实.本文从现代战争特点和物流业的发展出发,提出了构建军地一体化物流体系的设想,并给出了相关建议.     

影响我国农民市场主体地位确立的制度因素

拥有自主产权是农民成为真正市场主体的必要条件,包括诸如组织制度、户籍制度、金融制度、社会保障制度等在内的产权支持系统是影响农民成为市场主体的充分条件。市场主体地位的高低在某种意义上是由经济实体在参与市场经济活动时所拥有的权利束决定的。推进农村经济市场化的过程就是加强农民市场主体地位的过程。进一步深化农村体制改革,从根本上消除不合理制度对农民的束缚,使农民成为真正的市场主体是解决当前“三农”问题的根本出路。

Comparing the impact of management support on police officers’ perceptions of discretionary power and engagement: Australia,USA and Malta

Abstract

This paper uses Social Exchange Theory as a lens for comparing the impact of management support upon police perceptions of discretionary power and employee engagement, across three countries. A survey-based, self-report process collected data from 193 police officers in Australia, 588 from the USA, and 249 from Malta. Structural equation modelling was used to analyse the data. The findings suggest a significantly different management support context across the three countries, as well as significantly different perceptions of discretionary power. Across the three countries, police perceived relatively poor satisfaction with organizational management support and only some engagement levels. However, USA police perceived significantly more discretionary power than the other country samples. These findings provide greater clarity about the link between management support, discretionary power and engagement for the police officers. Since employee engagement likely affects policing outcomes, the findings suggest that poor management support of police officers could negatively affect the provided service. Potential strategies to enhance police engagement include (a) training police managers about how to manage so as to promote greater engagement, and (b) modifying police managers’ performance indicators in line with achieving better police engagement.     

台湾地区风险投资运作的经验借鉴及其启示

我国台湾地区风险投资业虽起步较晚,但由于政府大力扶植和组织管理模式创新等,已发展成为继美国之后的风险投资发展最好的地区。然而,国内学者一提到风险投资经验借鉴,首先就会想到美国。但事实上,美国现在风险投资业所处的金融环境、风险投资运作模式、科技经济水平、相关的法律、乃至于创业投资本身存在的目的和意义都与我国有很大的区别。相比之下台湾地区和大陆的风险投资业在起步之初,都是政府主导型的,而且起步期也大致相近,所以,台湾地区风险投资业的发展应对我们更有借鉴意义。本文通过从政府扶植组织管理模式等方面具体分析,总结和借鉴台湾地区风险投资发展的经验,对我国大陆风险投资发展的启示。     

Doing the right thing in the workplace: Responsibility in the face of accountability

Changing trends and the nature of the work force dictate increased personal responsibility by employees and expanded use of self-management practices. Nevertheless, organizations also feel the need to maintain external control. We propose a progressive view of accountability theory which can resolve the dilemma of how internal and external control can effectively coexist. Success of accountability forces is determined primarily by the relationship between the principal (party to whom one is accountable) and the agent (employee). The agent’s felt responsibility is enhanced to the extent that accountability leads to the structuring of expectations, the agent’s perceptions of the task or activity as significant, and the agent’s perception of control over the situation. Propositions that may be used to guide future research are offered throughout the article.

A Dynamic Leontief Model with Non-renewable Resources

In this paper we study a generalization of the dynamic Leontief input–output model. We extend the standard dynamic Leontief model with the balance equation of non-renewable resources. Obviously, the non-renewable stocks will decrease, exploiting primary resources. In this study we examine the controllability of this extended model by taking the consumption as the control parameter. Assuming balanced growth for both consumption and production, we investigate how long these scarce resources will cover the input needs of production and how the lifetime of the system depends on the balanced growth rate and on the consumption. In doing so, we apply classic results from control theory and on eigenvalue problems in linear algebra.
