Gender,culture and determinants of behavioural intents to adopt mobile commerce among the Y Generation in transition economies: evidence from Kazakhstan

This study investigates perceived risk and trust in relationship to the Diffusion of Innovation Theory [Rogers, E.M., 1962. Diffusion of innovations. Glencoe, IL: The Free Press; 1983. Diffusion of innovations. 3rd ed. New York: The Free Press] from a cultural perspective to understand the determinants of behavioural intent to adopt mobile commerce among the Y Generation in Kazakhstan. Surveys from 345 university-level students and subsequent structural equation modelling revealed perceived risk, trustworthiness and Rogers’ five innovation characteristics are important determinants. Perceived risk and trustworthiness are important determinants because of the high uncertainty avoidance characteristics of the Kazakh society. This study advances theory regarding culture- and generation-based characteristics to transition economies by verifying theoretical proposition regarding the behavioural intent towards mobile commerce adoption, resulting in a greater understanding of mobile commerce adoption among the Y Generation in transition economies. Marketing implications are discussed.     

Flood hazard maps in the European context

The implementation of the EU Floods Directive by water authorities across Europe has generated a lack of consistency in the present situation, especially regarding the scales adopted, the hydrological scenarios and the elements represented on flood hazard and risk maps. From the EU-funded project HYTECH, this article presents a general overview of Floods Directive implementation in eight European countries, highlighting the differences between them, with particular attention to flood hazard maps. For the implementation cycle that started at the beginning of 2016, a minimization of such differences is necessary in order to manage flood risk in a better and more integrated way.

梯级水电站施工导流风险效益补偿机制研究

汛期通过上游已建水电站调蓄可保障下游施工电站的度汛安全。为有效均衡上下游风险,合理分摊合作利益,对梯级水电站施工导流风险效益进行了补偿机制的设计。以总效益可量化为前提,提出补偿是落实风险效益分摊的一种支付行为,分别从补偿主客体的界定、责权利的划分、风险效益计量、补偿实施方式、补偿管理流程设计等方面,构建了梯级水电开发条件下施工导流风险效益补偿框架和程序。针对补偿制度实施存在的难点,提出了相应的对策和建议,可为流域梯级水电站风险效益补偿管理模式和制度的构建提供参考。     

A New Risk Assessment Approach for Cloud Consumer

The cloud computing introduces several changes in technology that have resulted a new ways for cloud providers to deliver their services to cloud consumers mainly in term of security risk assessment, thus, adapting a current risk assessment tools to cloud computing is a very difficult task due to its several characteristics that challenge the effectiveness of risk assessment approaches. Consequently, there is a need of risk assessment approach adapted to cloud computing. With such an approach, the cloud consumers can be guaranteed the effectiveness of data security and the cloud providers can win the trust of their cloud consumers. This paper requires the formalization of risk assessment method for conventional system as fundamental steps towards the development of flexible risk assessment approach regarding cloud consumers.     

简论电力财务预算管理与风险管理的关系

电力是现代社会生活、生产的重要能源之一。在电力行业不断发展进步的今天,由于其预算管理已无法满足时代要求,风险管理存在诸多漏洞,导致电力企业的发展受到一定的阻碍。这就需要我们充分分析电力企业的财务预算管理与风险管理的关系,并妥善处理二者间的问题,从而规避企业财务风险。     

软件测试工具分析及其应用探讨

结合实践探讨了在现有生产软件的中小型企业中,如何将软件测试与软件开发相结合,使软件测试管理的质量得以提升。介绍了一些目前常用的软件测试工具及测试管理工具,对软件测试管理中应注意到的80:20问题进行阐述分析,提出对测试管理中可能存在的风险可采取一些方法来应对。实践证明,使用全程软件测试管理对解决测试管理工作中存在的问题有很大帮助。     

需求依赖于价格情境下基于Copula-CVaR 的报童决策

探讨价格不确定下,需求-价格相关性与风险态度对决策行为的影响.建立随机需求与随机价格相关情境下基于Copula-CVaR的报童决策模型,Copula函数描述相关性,条件风险价值(CVaR)反映风险态度,证明了模型解的存在性和惟一性.蒙特卡罗模拟发现,需求与价格的相关性与风险态度对决策的交互作用使决策行为发生规律性变化,决策者对价格波动有一定容忍度,需求与价格相关性趋于不相关与完全负相关时市场趋于同质性.     

基于条件风险价值的零售商创新投资决策研究

研究了由风险中性制造商和风险规避零售商构成的供应链创新投资问题。通过运用条件风险价值（CVaR）对企业的风险偏好进行测度,构建了分散供应链和集中供应链两种情况下的企业决策模型,并根据数值实验对模型作了进一步的分析。研究结果表明：零售商越担心风险,其对创新的投入越少,并会减少销售量以应对市场风险,从而使得供应链的整体收益下降;分散供应链下的创新投入、销售量和供应链的期望收益低于集中供应链下的创新投入、销售量和供应链的期望收益。施行收益共享契约后,分散供应链下的创新投入和销售量达到了集中供应链下的决策水平,制造商和零售商的期望收益均得到提高。     

全生命周期软件过程风险管理模型研究

首先从软件过程的角度重新定义了过程风险的基本概念;然后结合CMMI和软件的生命周期分别从软件过程、生命周期和风险管理构建了三维结构的软件项目风险管理模型,提出了基于CMMI的全生命周期的过程风险策划、识别、评估和监控全过程模型;最后建立了软件研制风险管理系统,该系统在实际应用中取得了较好的效果。
