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。

引入供应链管理思想实现军事物流跨越式发展

供应链管理是物流管理的发展方向和趋势，是一体化的物流管理，是一种新的管理理念和模式。在军事物流领域借鉴和引入供应链管理思想，对提高军事物流保障能力和效益，促进军事物流跨越式发展提供了重要的契机和理论依据。本文从供应链管理的科学内涵、引入供应链管理的必要性以及应关注的几个问题等三个方面进行了论述。     

分数布朗运动环境下的美式看涨期权的定价方法

在分数布朗运动模拟算法基础上,提出了分数布朗运动环境下标的资产价格过程的一种数值模拟方法。然后应用于欧式和美式看涨期权定价。结果表明,该方法具有很快的收敛速度,而且基于最小二乘方法和偏最小二乘方法的美式看涨期权价格,都与对应的欧式看涨期权价格几乎完全一样。这恰恰验证了不支付红利的条件下,美式看涨期权不应该提前执行的理论论断。     

Do investors in Green Bond market pay a premium? Global evidence

We examine the pricing difference of Green Bonds (GB) and conventional bonds (CBs) in capital markets worldwide. Credit spread is used to observe whether investors would like to pay a premium for GBs over CBs. This study uses panel data regression with hybrid model to analyse daily observations over the period 2016 to 2017. We employ Option-Adjusted spread (OAS) to measure the credit spreads of bonds while controlling for bond specific, macroeconomic and global factors that influence the spread. With the hybrid model used in the panel data analysis, we were able to capture the fixed-effects of variables in a random effect model. We find that GBs are traded at a premium of 63 basis points (BPS), compared with a comparable corporate bond issue. We find that the green label provides issuers an incentive to raise funds through issuing GBs while providing investors an opportunity to diversify their investments returns. Our findings provide several implications to the major stakeholders driving the GB market to scale up the market to finance the required level of global green investment needs. We stress an urgent need to support the growth of the GB market to achieve sustainable development through mitigating climate change challenges.

考虑违约距离的上市公司危机预警模型研究

在上市公司财务危机预警中,违约距离起着重要的不可替代的作用,仅考虑财务指标并不足以完全解释企业财务危机发生的原因.文章应用Merton模型对2002～2004年ST公司和相应配对公司的危机发生之前的违约距离进行了研究,发现危机公司违约距离在危机发生前第三年明显低于正常公司的相应值,违约距离比传统财务指标能更早地预警到企业财务危机的发生.结合违约距离因素的危机预警模型能更明显地提高模型的危机判断正确率.     

宏观投资的影响因素与实证分析

在界定宏观投资的基础上，选择储蓄、价格、利润和利率等影响因素的代表变量，建立固定资产投资的理论模型；以1985－1999年为样本区间，采用SPSS统计分析软件包，对变量数据进行相关性分析和主成分分析，构建我国固定资产投资的回归模型；通过实证分析得出我国固定资产投资各影响因素的结论并给出相应的政策含义。     

黔西南“精神扶贫”工作开展的现状与不足

黔西南州是贵州省连片贫困的典型地区,是打赢脱贫攻坚战的关键区域。通过艰苦卓绝的奋斗,黔西南州的精准扶贫工作取得了重大成果。在“精神扶贫”领域,黔西南州在“扶智”“扶志”方面取得了很大成效,但还存在对“扶智”“扶志”认识不足、投入不足、主体错位,缺乏“扶智”“扶志”的文化自信等不足,这是持续打赢脱贫攻坚战面临的重大挑战。
