Bayesian MCMC Mapping of Quantitative Trait Loci in a Half-sib Design: a Graphical Model Perspective

Graphical models provide a powerful and flexible approach to the analysis of complex problems in genetics. While task-specific software may be extremely efficient for any particular analysis, it is often difficult to adapt to new computational challenges. By viewing these genetic applications in a more general framework, many problems can be handled by essentially the same software. This is advantageous in an area where fast methodological development is essential. Once a method has been fully developed and tested, problem-specific software may then be required. The aim of this paper is to illustrate the potential use of a graphical model approach to genetic analyses by taking a very simple and well-understood problem by way of example.     

The influence of personal and organizational values on marketing professionals' ethical behavior

The authors examine empirically the influence of personal and organizational values on marketing professionals' ethical behavior. The results indicate that personal and organizational values underlie differences in marketing professionals' ethical behavior, albeit small terms of the proportion of explained variance. The results also suggest the relationship between organizational values and ethical behavior to be significant. However, the same is not the case for the relationship between personal values and ethical behavior.Ishmael P.

Leading knowledge-workers through situated ambiguity

The paper explores how formal leaders make sense of and deal with autonomy of knowledge-workers. Based on interviews, I suggest that leaders make sense of knowledge-workers’ autonomy as ranging from perfectly autonomous to too autonomous to less independent to acting childish. This ambiguity was dealt with by making sense of leading as ranging from facilitative and supportive approaches to more controlling, even reprimanding acts. This empirical investigation of constructions of ‘leader/ship’ and ‘followers’ contributes to leader/ship-follower/ship literature. The paper’s contribution to theory lies in the notion of situated ambiguity; a way to understand the emerging way through which formal leaders navigate and smoothly move between their own differing perspectives, different practical situations, various culturally acceptable understandings of leaders and knowledge-workers.     

Key institutions in business and management education research

The authors investigate institutional productivity in business and management education (BME) research based on the analysis of 4,464 articles published by 7,210 authors across 17 BME journals over a 10-year period, involving approximately 1,900 schools worldwide. Departing from traditional disciplinary silos, they examine the BME research field as a whole by including all traditional business disciplinary areas and producing two top 100 rankings, one based on raw number of author publications and the other based on weighted scores reflecting journal quality and coauthorship.     

Quantitative Analysis of Foreign Trade and Environmental Efficiency in China

This article analyzes the relationships among trade, the economy, and environmental quality in China. First, in the context of these relationships, the Super-SBM model is used to calculate the environmental efficiencies of thirty Chinese provinces and cities to obtain the degrees of regional disparity. Second, China’s provincial panel data from 2003 and 2012 are used to establish an influential factor indicator system of environmental efficiency. A section-weighted fixed effect model then provides insights about influential factors such as spatial heterogeneity. Third, the article establishes a variable coefficient model to identify the relationships among the objects of the study and divides the Chinese regions into four types. The suggestions include enhancing environmental and business regulations to ensure equilibrium between trade, the environment, and local economies.     

Formalisation of land rights: Some empirical evidence from Mali, Niger and South Africa

In this paper, we re-interpret three cases of research previously carried out in Mali, Niger and South Africa in light of the recent debate about formalisation of land rights that has emerged since the publication of Hernando de Soto's ‘Mystery of Capital’. The Malian case shows that lack of broad access to formalisation processes in high-pressure areas may play into the hands of those with power, information, and resources. The case also demonstrates that timing of formalisation efforts in urban areas characterised by rapid expansion is crucial in terms of distributive outcomes. The Nigerien case demonstrates how impending formalisation led to a scramble for land and increased conflicts in a context of institutional competition and limited administrative capacity. The South African case shows that the very process of surveying and registering rights may also change the rights themselves. Formalisation procedures may also amplify the tension between individual and communal rights, and boost privatisation.     

京沪高速铁路生态现代化的思考——基于区域生态系统项目的技术经济评价模型

京沪高速铁路生态系统建设将是中国东部六省市率先实现生态现代化的重大契机,正外部性效应是京沪高速铁路生态系统项目技术经济评价的主要特征,管理部门有必要定量测算其复合生态系统的生态正外部性并使正外部效应内部化.根据京沪高速铁路生态系统的收益应该等于其具有私人品属性的正产品收益和具有正公共品属性的副产品收益之和这一原理,可以设计京沪高速铁路生态系统技术经济评价的三个主要指标,它不仅可以用于其项目评价,而且从理论上为政府最大限度地支持生态系统的发展,提供一个定量测度的工具.     

考虑环境因素的中国电力能源效率测度与改进

在界定全要素电力能源效率概念的基础上,构建了考虑环境因素的非径向全要素电力能源效率DEA模型。利用相关数据,从省际、区域两个层面对我国30个省(自治区、直辖市)的电力能源效率进行测度分析。结果显示:在全国30个省(自治区、直辖市)中,只有14个省区的电力能源效率是有效的,且这些省区不存在电力节能潜力;北京、天津、上海三大城市的平均电力能源效率最高,西部地区的该均值最低;我国省际电力能源效率存在显著的区域性差距,且4大区域的电力能源效率存在一定的梯度差距;对省区进行投入、产出调整,可使全国的电力消费量缩减6309.08亿千瓦小时。最后提出提高我国电力能源效率的政策建议。     

HOUSEHOLD FOOD CONSUMPTION: THE INFLUENCE OF HOUSEHOLD CHARACTERISTICS

This paper reports an attempt to identify the effects of various household characteristives on household food consumption. The analysis was based on National Food Survey (NFS) data for Great Britain for the calendar year 1982. Consumption (per person per week) of various food items was related to each of the main household characteristics on which information is collected in the course of the Survey-location (both country/region and type of area), income (generally of the head of the household), household composition, age of housewife, housing tenure and freezer ownership. The results indicated that all these variables are important in the explanation of households' food consumption patterns.
