A statistical review of the risk associated with offshore support vessel/platform encounters in UK waters

Safety performance on the UK Continental Shelf is normally considered to be of a high standard, although there are still many incidents and accidents. This paper discusses some of the initial findings in an offshore support vessel safety research project. Following a brief review study of the uses of various types of existing offshore support vessels, a comprehensive statistical failure data analysis of the vessels is carried out mainly based on a Ship/Platform Incident Database drawn from the Health and Safety Executive (HSE). The variation of incident frequency with time for different types of offshore oil and gas installations, and for different vessel types has been established. A total of 394 records within the period 1980 to 1997 are investigated in this study. The variation of incident frequency with time and seasons, causation factors, incident with respect to geographical distribution, and sea conditions are discussed. The relationship between vessel types, sizes and operations is analysed; operating circumstances, reported primary failure cause, and impart orientation for different vessel types are also described. The statistical analysis reveals that safety culture in terms of good seamanship by vessel masters is probably responsible for mitigating the magnitude of many of the impacts that do occur and also that there is a need for improvement in safety performance. Issues pertaining to human element, the availability and reliability of data, risk criteria, and safety culture in the context of marine and offshore risk assessment are also discussed.     

中国涉农供应链管理研究:现状与问题分析

近十二年间,在实践推动及学科交叉互动的背景下,我国涉农供应链(ARSC)研究发展很快,并呈现出一些鲜明的特征。从功能和职能视角看,质量安全、可追溯、冷链、利益与关系管理等方面成为研究的热点。但总体上,这一领域存在着定位模糊、功能性研究薄弱、理论体系散乱、个案挖掘与实证分析不足、连续研究乏力和成果泛化等突出问题。此外,与国外研究相比,一些难点、重点现实问题及其他前沿问题的研究亟需展开。为此,本文对中国涉农供应链管理研究的现状和存在的问题进行了分析。     

非寿险产品EVA盈利分析

近年来，我国保险市场发展迅速，保险产品日趋多样化。由于保险产品成本的事先未知性，寻求一种方法对保险产品进行盈利分析显得越来越重要。基于Feldblum的思想，结合我国保险实务，本文建立了关于我国非寿险保险产品的EVA盈利分析模型。分别在净现值和内部收益率两种会计体系下给出了动态监测保单盈利能力的方法。     

激励相容视角下的煤矿安全规制成本分析

2009年山西“2．22”重大煤矿安全事故,提醒我们反思当前的煤矿安全规制体制,其中,我们就有必要探究煤矿安全规制中的成本问题。通过逻辑推理、演绎,试图以契约经济学为基础,从激励相容的视角,系统分析煤矿安全规制体制中存在的代理成本及影响代理成本的相关因素．     

基于农业信贷净投入视角下我国农村经济影响因素的实证研究

本文在对研究农业信贷资金与我国农业GDP、农民收入等农村经济发展指标关系的国内外研究文献进行梳理和总结的过程中发现,现有研究过程和研究结论没有将农业信贷资金投入和农村资金外流两个相互影响的资金因素系统地进行考量,而是将二者人为割裂;同时在农村经济发展指标选取上也存在着不全面的问题。基于此,本文提出了“农业信贷净投入”的理论观点,将农业信贷投入与农业存款之间的差额作为分析变量,对我国在1993-2007年的农业经济指标进行了实证分析,并提出了相应的观点与建议。     

The fourth industrial revolution,agricultural and rural innovation,and implications for public policy and investments: a case of India

The Indian Government and public–private partnerships are developing and disseminating a dizzying number of innovative, networked solutions, broadly known as the Digital India initiative, to increase the efficiency of safety nets and worker productivity and to improve life. Yet, challenges to turn the power of information and other technologies into a farmer‐friendly technological revolution for India's 156 million rural households are considerable, including: (1) reliable, up‐to‐date, location‐specific message content for a diverse agriculture to help stratified households shift to productive, knowledge‐intensive agriculture as a business—government, private sector, and civil society have big roles to play; (2) digital literacy, i.e., teaching farmers how to choose and use apps, even where the digital divide is absent; apps are, or soon to be, in regional languages; and (3) monitoring actual use and impacts on users’ lives by understanding the adoption and adaptation processes. These challenges call for bottom‐up, complementary investments in physical, human, and institutional capital, and farmer‐friendly e‐platforms, while forging ahead with many top‐down policy and institutional reforms currently underway, in which progress is real and constraints holding back greater success are better understood.     

The effect of psychological empowerment climate on restaurant food safety,food quality,and financial performance

ABSTRACT

Consumer food safety incidences that result from employee accidents and behaviors can be detrimental and costly to a restaurant organization. Restaurant organizations and hospitality researchers have sought multiple methods of increasing food safety performance through training and intervention, but this study suggests that shared agreement of psychological empowerment may be a key factor in improving food safety performance, and in turn, food quality and store revenues. Using data from a national chain of quick service restaurants, this study used groups of restaurant employees’ psychological empowerment as an antecedent to food safety performance, measured in a food safety audit, and found significant support. Moreover, using consumer evaluations of food quality and the organization's store revenue records, indirect and direct relationships among psychological empowerment, food safety performance, food quality, and revenues were found. Theoretical and practical implications are discussed.     

基于消费者认知失调的安全认证农产品选择行为研究

消费者对安全认证农产品的自述偏好与现实选择的不一致性表现为消费者的认知失调现象,认知失调程度越高的个体采取措施缓解认知失调情绪的动力就越强烈,因此深入探究消费者认知失调后对安全认证农产品的行为选择构成了本文的研究起点.本文基于江苏省和安徽省840份实地调研数据,结合认知失调理论和理性行为理论,运用二元Lo-gistic...     

机构投资者参与公司治理的决策研究——基于绝对净收益的视角

为了改善我国上市公司治理,提高上市公司的绩效并促进股票市场的健康发展,政府监管部门出台了一系列促进机构投资发展政策和措施。机构投资者得到了巨大的发展。但是,机构投资者的发展对改善上市公司治理的作用受到质疑。本文通过构建理论模型,采用监督绝对净收益的标准分析机构投资者参与公司治理的决策情况。研究发现,机构投资者监督绝对净收益大于零,就会参与到公司治理中。
