大学生价值观与电信服务消费决策风格的关系研究

目前,在消费者行为研究领域里,从价值观的角度去研究消费者购物决策风格是被广泛关注的课题。本研究主要采用问卷调查法对651名大学生的价值观和电信服务消费决策风格进行考察,目的在于探寻大学生价值观与电信服务消费决策风格之间的关系。在文献回顾与数据收集的基础上,进行了探索性因子分析、验证性因子分析和相关分析,最后指出研究结论和局限性。     

基于多目标决策的流域水系统资源承载力分析——以浏阳河流域为例

在阐述河流流域水系统承载力的内涵及衡量指标,分析河流流域水系统承载关系的基础上,以人口、经济和环境为目标,以供水量、污染容量以及人口规划和工农业产值规划为约束,建立了基于多目标决策的流域水系统资源承载力优化模型。以浏阳河为例分析得出,按照浏阳河流域的可供水量、理论纳污容量和人口、经济发展规划速度,若以环境优先为前提,2015年浏阳河水系统资源承载能力满足要求,若以经济优先为前提,则基本满足要求;而无论是以环境优先还是以经济优先为前提,2020年均会出现水系统资源承载能力无法满足要求的情况。进而提出了浏阳河流域可持续发展管理对策。     

石油战略储备方式的成本分析及选择

为了定量分析各种石油储备方式的优劣程度,在定性分析常用储备方式及其特性的基础上构建了占用陆地面积、输油管道长度、建设周期等8项指标的石油战略储备方式评价指标体系;采用模糊综合决策方法,定量评价各种石油储备方式的优劣,并应用于中国的石油战略储备方式选择。分析认为：地下盐穴储备方式最优,地下岩洞储备方式成本最高;石油战略储备方式选择的模糊综合决策可为储备基地储备方式选择提供依据,也可以从理论上完善石油战略储备体系。     

经济学视角下交通基础设施政府和社会资本合作(PPP)研究新进展

为促进经济健康稳定可持续发展,提高交通基础设施公共服务质量、增加公共产品有效供给,从经济学视角出发,对国内外学者近年来关于交通基础设施建设中政府和社会资本合作(PPP)的研究成果进行梳理,按照文献的发展脉络和逻辑关系对交通基础设施PPP进行总结和概括,从项目定价、公私合作、风险承担和绩效评估四个维度探讨相关研究的新进展。研究发现,交通基础设施建设PPP的研究越来越多,对实践的影响也日渐增强; 从项目定价和公私合作这两个维度对交通基础设施建设相关PPP的研究更具有规范性,而风险承担和绩效评估创新性地从制度经济学和管理学角度对交通基础设施建设PPP项目进行了研究; 未来从经济学视角开展PPP研究,需要运用更加宏观的视角,整体研究和阐述PPP中的系列问题,从政府部门、企业、责任单位、管理层、社会效用等多个角度提出改进路径,这对整体提升国内公共基础设施领域PPP取得社会成效乃至经济高质量发展程度都具有积极意义。     

基于信息熵的工程项目风险决策

风险是工程项目决策中的关键因素,由于对影响和制约工程项目的风险因素缺乏有效的评价,造成工程项目中普遍存在决策困难的现象。在工程项目风险决策中引入熵的概念及理论,建立基于信息熵的工程项目风险分析模型,通过定义评价熵与判断熵得到综合信息熵,然后利用综合信息熵对工程项目风险进行度量,以此对工程项目进行风险决策,并通过算例说明该方法的优越性和广阔的应用前景。     

Feeling at home: Korean Americans in senior public housing

What are older Korean immigrants' cultural conceptions of home arrangements and environments? Does aging affect their family relationships? Why do they decide to move to public housing? How do they adapt to and re-create a feeling of home in public housing? This research in the field of aging-and-environment focuses on these questions. Based on a naturalistic field research of older Korean immigrants to the USA this paper details the transitions from loss of feeling of home in their pre-move life, the decision to move to senior public housing, to settling into the new apartment. The themes delineated are: 1) shifting roles in multigenerational households, 2) altered conceptualizations and changing environments, becoming dut-bang no-in (guest in own home), 3) detachment from prized objects, and 4) re-creation of meaningful environment. Revealed are the complex and interwoven nature of the decision to move involving experiences, events, and nested mini-decisions, as well as the emotional disruptions, loss of sense of self, and detachments that occur. The adjustments made by these older adults to the culturally inappropriate design in order to regain feeling at home are described. Several socio-physical phenomena and concepts identified are: a) spatial oblation, b) environmental and object detachment, c) object meaning linked to persons, and d) planned surrender or disposal of cherished objects.

Managing key interfaces in production planning and control

Detailed observational research, undertaken in two large and complex manufacturing businesses, identified ways in which work groups interface to employ knowledge to perform production planning and control activities. Eleven interfaces were observed and methods were established to classify them into types based on how knowledge is communicated and shared. Characteristics of the decision-making environment on either side of each interface were identified to explore their impact on interface type. Key differences in decision-makers’ predominant modes of decision-making, their agendas, and the form and scope of their knowledge were found to influence communication and decision-making processes. These findings have implications for production planning and control organisation and process design. In particular, it is seen that the effectiveness of interfaces may be improved through the alignment of decision-making approaches, agendas and knowledge across interfaces and/or through the effective use of interface tools that enable decision-makers to understand the consequences of decisions made.     

Uncertainty in competitive bidding – a framework for product–service systems

Owing to servitisation, manufacturing companies are increasingly required to compete through the provision of services around their products. The contracts for these services are often allocated through competitive bidding where the potential suppliers submit a price bid to the customer. The pricing decision is influenced by various uncertainties. This article proposes a conceptual framework depicting these influencing uncertainties on the bidding strategy. This framework is based on three empirical studies with industry investigating different viewpoints on the decision-making process. The intention is to support the pricing decision when competitively bidding for a service contract. The framework can be applied to specific competitive bidding situations to identify the influencing uncertainties, model them and depict their influences on the pricing decision.     

城镇化过程中农民参与乡村公共决策的代理路径分析

在乡村治理中,农民参与能力的强弱决定着参与决策的实际效果。通过对农民参与能力的分析,以农民参与能力为中心,基于几何分析的方法,积极探索农民参与能力与借助代理之间的关系,形成了村民导向型、共同协作型和代理导向型等三种主要的关系模式,并以此为指导,从农民、政府和制度环境三个层面构建农民参与乡村公共决策的互动模式的路径和方式,引导农民理性有序参与乡村公共决策,促进乡村治理的良性发展。
