三级生物质供应链的奖惩与回馈契约协调研究

为了优化生物质能供应链,降低成本,在无扰动因素情况,需求不确定且与价格有关的条件下,研究了由能源公司、基地和农户组成的三级生物质供应链中,奖惩与回馈契约对供应链的协调问题,建立了满足渠道协调的条件和供应链内各级参与者实现互赢的数学模型,最后将其用于数值算例中验证。结果证明契约参数的合理选择可以实现供应链各方利益最大。     

基于多元结构的旅游供应链协调机制研究

根据组织协作观点与步骤选取了合适的协作者、协作要素；摒弃了旧有的供应链的唯一机制，运用包含服务、资料、金钱、知识的多样化机制合理地调整了旅游供应链；鉴于旅行社与政府在调整供应链上存在的不足，给出了微观与宏观相融合的协调机制；在分析当前旅游供应链中常见的折扣价格合约制度后，建立了全新的收入分配体系，目的在于鼓励提供旅游产品的供应者；在分析旅游供应链利得产品驱动模型后，给出了产品的推拉协调一致的模型。     

影响高职院校实践教学质量的因素及对策分析

实践教学是高职生获得职业能力的重要途径，随着实践教学比例的提高，出现的问题也不断增多，特别是实践教学中学生被沦为廉价劳动力的现象，已引起社会愈来愈多的关注。本文基于狭义实践教学条件下，对影响高职院校实践教学质量的主要因素进行了分析，并根据影响因素提出了相应对策。     

基于资源环境约束下的休闲观光农业园游客满意度研究——以北戴河集发农业园为例

文章基于资源环境的约束,以北戴河集发休闲农业观光园为例,针对影响客户满意度的问题运用问卷调查法,即发放、搜集、收回和整理问卷,进行调查并数理统计。其中,高达95.8%问卷回收率,保障了问题研究所用数据的科学性、规范性和客观性。基于国、内外游客满意度的研究现状,在前人游客满意度分析模型研究基础上,根据实际所得数据建立了休闲农业观光园游客满意度分析模型——因子模型。因子模型是利用加权平均法计算权重函数的权重值,得到客户满意度的指标权重,对实际所得数据按照上述步骤处理,运用因子模型计算得到客户处于中等满意度的结论。该研究对因子模型进行了检验,证明了模型的有效性,提出了当前休闲农业发展的短板和需要提高的方面,为以后休闲农业的发展提供了侧重方向。     

环境规制、能源消费结构与雾霾——基于省际面板数据的实证检验

采用我国30省(市、区)2003—2012年面板数据,分析环境规制强度、能源消费结构与雾霾之间的关系。首先,以PM10浓度指标进行聚类,把30省(市、区)划分为高、中、轻三大污染地区。其次,面板单位根检验结果显示各变量是一阶单整I(1);Pedroni和Kao协整检验表明变量之间存在协整关系;FMOLS回归发现,全国总体环境规制强度与PM10浓度呈反方向变动,能源消费结构与PM10浓度呈同方向变动;高污染地区能源消费结构对PM10浓度产生正的影响,中、轻污染地区环境规制强度对PM10浓度产生负的影响。最后,提出了使用法律、经济手段加强环境规制,降低煤炭消耗比例、发展清洁能源等建议。     

Text and metatext in the resource‐based view

This paper distinguishes between text and metatext in the resource‐based view (RBV) – that is, the actual words and logic fundamental to the RBV (the text) and the traditions, interpretations and applications of the theory (the metatext). It argues that Kaufman's ( 2015 ) criticism of the RBV as applied to strategic human resource management actually focuses on RBV metatext and not text. Indeed, unlike some RBV metatext, RBV text actually has a great deal to say about research and practice in strategic human resource management.     

市域城镇体系空间布局研究——以河南平顶山为例

城镇体系的空间结构研究是人文地理学研究的重要方向。城镇体系的空间结构是否合理,对区域经济的发展有一定作用。文章采用定性分析与定量分析相结合的研究方法,对平顶山市域城镇体系规模等级、地域空间结构、市域经济发展水平等现状进行分析,通过运用断裂点公式对平顶山市域中心城市辐射影响范围进行定量计算,剖析平顶山市域城镇体系存在如下问题:城镇体系人口规模等级差异大,城镇化率基础好于全省平均水平,城镇化水平发展不平衡,城镇体系空间结构状态非均衡等。根据研究区域情况,对平顶山市域城镇体系进行布局构想,即打造叶平宝鲁一体化核心区为引领,加强3个卫星城市的发展为带动,做好小城镇的生态建设,完善市域交通网络建设,推进产业集聚区的建设,建立起一个等级清晰、核心突出、职能明确的"一心三卫三层"网络型城镇体系。     

Structuring an effective human error intervention strategy selection model for commercial aviation

Flight safety cannot be compromised. Thus, commercial airlines should constantly develop safety management strategies to mitigate the diverse hazardous factors in flight operations. Given the constraint of organizational resource, a commercial airline may not have sufficient resources to implement all the necessary strategies simultaneously. This study uses a well-structured process to develop a qualitative evaluation model that will enable airlines to identify human errors and select an intervention strategy with the highest success potential. To clarify the decision problem, the Human Factors Intervention Matrix framework is utilized to construct the decision hierarchy. The Analytic Hierarchy Process is then used to attain the priorities of potential alternative strategies for various unsafe acts. Finally, Zero-One Goal Programming models are formulated to select an optimal portfolio based on the specific target and the available organizational resources. An empirical study is presented to illustrate the application of the proposed model. According to the results of the combined model, an optimal portfolio, including the intervention approaches of organizational/administrative, human/crew, and operational/physical environment, can remediate four unsafe acts, namely, decision errors, skill-based errors, perceptual errors, and violations, under resource constraints of the organization.     

Assessing time-varying stock market integration in Economic and Monetary Union for normal and crisis periods

In this paper, we examine the stock market integration process amongst 17 Economic and Monetary Union (EMU) countries from January 2002 to June 2013 over a normal period as well as for the Global Financial Crisis (GFC) and Eurozone Debt Crisis (EDC) periods. We classify the economies in three groups (A, B and C) based on their GDP to examine whether the economic size influences financial integration. Seven indicators are used for the purpose, namely, beta convergence, sigma convergence, variance ratio, asymmetric DCC, dynamic cointegration, market synchronisation measure and common components approach. The results suggest that large-sized EMU economies (termed as Group A) exhibit strong stock market integration. Moderate integration is observed for middle-sized EMU economies with old membership (termed as Group B). Small-sized economies (termed as Group C) economies seemed to be least integrated within the EMU stock market system. The findings further suggest presence of contagion effects as one moves from normal to crisis periods, which are specifically stronger for more integrated economies of Group A. We recommend institutional, regulatory and other policy reforms for Group B and especially Group C to achieve higher level of integration.
