A Bayesian Network Estimation of the Service‐Profit Chain for Transport Service Satisfaction

Bayesian network methodology is used to model key linkages of the service‐profit chain within the context of transportation service satisfaction. Bayesian networks offer some advantages for implementing managerially focused models over other statistical techniques designed primarily for evaluating theoretical models. These advantages are (1) providing a causal explanation using observable variables within a single multivariate model, (2) analysis of nonlinear relationships contained in ordinal measurements, (3) accommodation of branching patterns that occur in data collection, and (4) the ability to conduct probabilistic inference for prediction and diagnostics with an output metric that can be understood by managers and academics. Sample data from 1,101 recent transport service customers are utilized to select and validate a Bayesian network and conduct probabilistic inference.     

我国新时期翻译批评模式研究:成果与趋势

20世纪80年代以来,随着西方译论的大量引介,理论化、研究方法科学化、模式化的观念不断涌现,国内翻译批评研究呈现出"百家争鸣"的新局面。在语言学翻译批评模式方面,将翻译批评与语言学知识结合起来,分别从不同的语言学视角去研究翻译批评现象,使其更为科学客观;在文化翻译批评模式方面,打破了语言学范式在译学研究中的主导地位,结束了以语言为中心的静止的研究局面,影响译文形成过程的外部因素开始进入学者的视野,使得翻译批评研究更为全面,视野更为开阔;在文艺学翻译批评模式方面,将翻译批评建立在美学与文艺理论基础之上,强调翻译中的审美体验和艺术生成,翻译批评的观念和方法也随之发生了变化。鉴于翻译批评研究的人文社会科学性质,未来的翻译批评模式研究既要在宏观上坚持人文方向,又不失微观分析的客观性。     

基于主成分聚类分析的城市基础设施建设水平评价研究

我国目前正在全面创建和谐社会时期,城市基础设施的建设就成为社会发展中重要的研究课题。本文阐述了城市基础设施建设的重要作用,选取了评价城市基础设施水平的典型指标;最后以2005年全国31个主要城市的数据为例,利用主成分聚类分析的方法说明指标和评估模型的应用。     

影响英语听力理解的因素及对策

从英语学习者主体的角度分析了对听力的影响,如学习者对语法和词汇量的掌握程度、语音语调的准确性、对听力内容的敏感性、速记的速度以及听者的情绪状态。由此．建议英语学习者从提高自己的英语知识储备、在听力训练的过程中利用音乐辅助手段以及无意识的学习等方法来提高英语听力。     

INTERNATIONAL NARCOTICS TRADE,FOREIGN AID,AND ENFORCEMENT

Using a general equilibrium model of a developing narcotics‐producing and ‐exporting economy, we analyze the economic effects of policies designed to restrict the production and trade of narcotics: foreign aid tied to anti‐narcotics law enforcement activities, demand reduction policies, and alternative development policies. We characterize the problem as one of serious factor market distortions introduced by illicit production and enforcement. While aid to enforcement generally reduces the production and export of narcotics, it is less effective for economies with market power, and under plausible conditions may raise narcotics output and have negative welfare implications for the recipient.

THE EFFECTIVENESS OF FAMILY THERAPY IN THE TREATMENT OF ADOLESCENTS WITH CONDUCT DISORDERS AND DELINQUENCY

A literature review was conducted on recent studies using family therapy approaches to the treatment of conduct disorders in adolescents. Results from studies conducted since the Shadish et al. (1993) meta-analysis on the effects of family and marital therapies are included. Barriers to effective treatment are identified, costs of care are discussed, and a variety of systems of care in which family interventions are embedded are reviewed.     

Producing More Milk on Fewer Farms: Neoclassical and Neostructural Explanations of Changes in Dairy Farming1

Neoclassical theory in economics has served as the guiding paradigm for agricultural development in the United States. At one level, this model emphasizes the substitution of capital in the form of machinery and chemicals for land and labor. At another level, the paradigm calls for the introduction of mass production techniques, such as product standardization and the routinization of labor processes. Using data on dairy farms and dairy processors from the 50 states, the neoclassical model accounts for changes in productivity on dairy farms; however, the model is less useful in accounting for changes in dairy farm structure. To explain changes in structure, recent neostructural theory that links the structure of markets to the structure of production is used. It is concluded that persistence of family-size dairy farms may rest more on developing and protecting markets for the milk they produce than with tinkering with the neoclassical model.
