中小上市公司治理结构与会计信息透明度关系研究

完善的公司治理结构对会计信息披露有着积极的作用,会计信息披露亦有助于提高公司治理和经营管理透明度。经对2007-2010年深市样本中小上市公司Logistic回归分析,结果表明:第一大股东控制力、董事会规模和公司规模与会计信息透明度正相关;独立董事比例、董事长与总经理两职合一和资产负债率与会计信息透明度负相关;监事会规模与会计信息透明度无明显的相关性。     

Accrual output based budgeting systems in Australia The rhetoric-reality gap

This paper describes accrual output based budgeting (AOBB) systems and examines their adoption in Australia. An analysis of claims made about AOBB systems by central agency reformers is set out, and the conclusion offered that these claims are fundamentally rhetorical in their characteristics. These rhetorical claims are contrasted against a critical analysis which suggests that despite the claims made by reformist elements in favour of the adoption of these systems, the structural and empirical elements of AOBB systems as implemented in Australia raise considerable doubts as to whether suggested benefits will be realised in practice.     

Resource Allocation in Higher Education in The Context of New Public Management

Abstract

The public administration framework New Public Management (NPM) has been applied to higher education systems in many western countries. The literature on these reforms reports on some positive effects but many critical voices can also be found. Even though NPM as a narrative unifies principles and measures under one roof, a detailed analysis shows that NPM principles fit differently for different tasks. Using a contingency approach, we show that, within the NPM narrative, two different higher education funding approaches exist, namely high-tech versus high-touch. Our study confirms the theoretical proposition that high-touch approaches match better with higher education domains. The use of contingency theory to classify NPM measures thus might be a promising way to further advance NPM theory and its practical application to topics as controversial as academic funding.     

Distinctiveness in the study of public management in Europe

Abstract

This article presents three clear examples of distinctive approaches to the study of public management, that is, in France, Germany and Italy, three countries with peculiar legalistic state traditions. For each country a historical sketch of state and administration is first given, then both the administrative (public management) reforms are described, the state of the art of administrative sciences and finally the specificness of the study of public management. The historical-institutional context of a particular state and administration apparently does influence not only the form and content of the administrative ‘public management’ reforms but also the scientific study of public management in that country.     

Towards A Better Understanding of Public Service Motivation and Mission Valence in Public Agencies

Abstract

Research has not fully considered how public service motivation (PSM) and mission valence may work together to influence job satisfaction, extra-role behaviours, and turnover intentions. As a result, a causal model was developed and tested on local, state, and federal government employees in the United States. The results indicate that PSM had a direct effect on mission valence and extra-role behaviours. They also revealed that mission valence fully mediated the relationship between PSM and job satisfaction and partially mediated the relationship between PSM and extra-role behaviours. On the other hand, mission valence did not mediate the relationship between PSM and turnover intentions. These findings are thoroughly discussed in this article.     

Risk management by SPV partners in toll road public private partnerships

ABSTRACT

Research on risk management in Public Private Partnerships (PPPs) has largely overlooked that the Special Purpose Vehicle (SPV) is made up of several project partners with different interests and objectives to manage risk. This paper makes an important contribution to this literature as it articulates SPV partners’ perceptions of how they manage risk in toll road PPPs. Our case studies show that the different skillsets of both the international and domestic partners with their sub-contractors provide opportunities for mitigating and managing risk but also pose potential problems in terms of measuring and obtaining value for money for taxpayers.     

Demographic determinants of public service motivation: a meta-analysis of PSM-age and -gender relationships

ABSTRACT

Although age and gender are among the most analysed determinants of public service motivation (PSM), their effects on PSM development remain unclear due to contradictory findings among studies. To address this issue, we carried out a meta-analysis of PSM-age and -gender correlations, synthesizing findings from 30 independent samples, with pooled sample sizes as large as N = 86,958. Moreover, we considered the role of cultural context as a moderator of these relationships. Overall, we found that age and gender are indeed antecedents of PSM, but importantly, that these effects differ across cultural contexts. Implications for research and practice are discussed.     

How does public participation affect perceptions of public–private partnerships? A citizens’ view on push,pull, and network approaches in PPPs

ABSTRACT

In this study, we analysed US-based public opinion data to determine the influence of particular modes of participation on citizen perceptions of public–private partnerships (PPP). Our summary finding is that information dissemination can improve community support of PPPs, but interactive engagement is more important, and likely required, for assuring citizens that projects reflect their interests – an issue vital to the long-term sustainability of PPPs. Counter to expectations, respondents indicated a preference for meetings with private partner representatives over those with their public sector counterparts; implying the value of citizen-direct relationships in holding third-party providers to account.     

Turbo码的Taylor-Log_MAP译码算法

以Turbo码基本理论和算法为基础,依据无线信息传输的实际要求和Taylor级数的基 本原理,提出了一种Turbo码的Taylor-Log-MAP高效译码算法。该算法对基本的Log-MAP 算法中K运算利用Taylor级数进行展开,针对实际的信道需求对展开式进行截断,实现了Tur bo码 的最佳译码。与传统的对数域最大后验概率译码算法相比,该算法基本保持了优良的译码 性能,同时避免了复杂的对数运算,减小了运算量。仿真结果表明,与现 有的RS码性能相比,使用Turbo码可以获取5 dB的信噪比增益。
