We analyze markets in which the price of a traded commodity is such that the supply and the demand are unequal. Under standard assumptions, the agents then have single peaked preferences on their consumption or production choices. For such markets, we propose a class of Uniform trade rules each of which determines the volume of trade as the median of total demand, total supply, and an exogenous constant. Then these rules allocate this volume “uniformly” on either side of the market. We evaluate these “trade rules” on the basis of some standard axioms in the literature. We show that they uniquely satisfy Pareto optimality, strategy proofness, no-envy, and an informational simplicity axiom that we introduce. We also analyze the implications of anonymity, renegotiation proofness, and voluntary trade on this domain.  相似文献

This paper applied the family stress model to the case of Turkey in the wake of the 2001 economic crisis. Using structural equation modeling and a nationally representative urban sample of 711 married women and 490 married men, we tested whether economic hardship and the associated family economic strain on families resulted in greater marital problems. Our results showed a modified family stress model applies to Turkey. In contrast to most previous research, economic strain had a direct effect on marital problems, and the indirect effect of strain, via emotional distress, was only significant for women. The results were interpreted in light of social and cultural factors that condition how economic distress affects marital relations.  相似文献

This paper presents a comprehensive comparison of well-known partially adaptive estimators (PAEs) in terms of efficiency in estimating regression parameters. The aim is to identify the best estimators of regression parameters when error terms follow from normal, Laplace, Student's t, normal mixture, lognormal and gamma distribution via the Monte Carlo simulation. In the results of the simulation, efficient PAEs are determined in the case of symmetric leptokurtic and skewed leptokurtic regression error data. Additionally, these estimators are also compared in terms of regression applications. Regarding these applications, using certain standard error estimators, it is shown that PAEs can reduce the standard error of the slope parameter estimate relative to ordinary least squares.  相似文献

Currently, the construction of a ‘Harmonious Society’ is an important yet challenging official project in the People's Republic of China. Under Chinese Communist Party supervision, the government has undertaken some measures to achieve this goal. In the country's capital, Beijing, the majority society (‘social majority’) is composed of peoples considered to be Han Chinese (), but the population there also includes representatives from 55 recognised minority society groups (). Many such latter groups, especially Uyghurs and Tibetans, have long maintained distinctive cultural traditions, practices, languages, and ‘memories’ from those of the majority society – and are ‘different’ in physical appearance, customary dress and other features. Officially, however, all are ‘Chinese citizens’ (). Recently, some negative and disharmonious trends have appeared in majority-minority relations. Based on academic fieldwork research, this essay focuses on ‘Uyghur intellectuals’ in Beijing, analytically discussing their relationships with the majority society there, identifying issues and problems in those relationships, and offering informed, constructive suggestions to achieve a more ‘Harmonious Society’ in China.  相似文献

Background: Disclosing the sexual abuse may be related on many individual and/or environmental factors in all age groups. The sociocultural context is the most influential factor of the disclosing process especially for those living in patriarchal cultural values. This study compares the impacts of sexual abuse and other sociodemographic variables between recanting and non-recanting victimized groups in Adana city from Turkey.

Methods: The samples attending our department were divided into two groups: group 1 comprised victims who recanted their first abuse disclosure, and group 2 comprised victims who insisted on the veracity of their first report at further evaluations. The characteristics of the child, family, and abuser were compared between recanting victims and non-recanting victims by retrospective data.

Results: Each group included 27 children, for a total of 54 subjects. All adverse social reactions after the sexual abuse, including keeping secrets and a repressive family attitude, were higher among group 1 victims than group 2 victims (p < 0.0001).

Conclusions: Although they are victimized by protecting family integrity, victims may show a tendency to keep secrets and to not immediately disclose an abuse event.  相似文献

Risk management in supply chains has been receiving increased attention in the past few years. In this article, we present formulations for the strategic supply chain network design problem with dual objectives, which usually conflict with each other: minimizing cost and maximizing reliability. Quantifying the total reliability of a network design is not as straightforward as total cost calculation. We use reliability indices and develop analytical formulations that model the impact of upstream supply chain on individual entities’ reliability to quantify the total reliability of a network. The resulting multiobjective nonlinear model is solved using a novel hybrid algorithm that utilizes a genetic algorithm for network design and linear programming for network flow optimization. We demonstrate the application of our approach through illustrative examples in establishing tradeoffs between cost and reliability in network design and present managerial implications.  相似文献

The overall goal of the study reported herein was to use techniques in the field of risk assessment (specifically a state-space population dynamic model of disease transmission within recreational waters) to explore the relative significance of (1) active shedding of microorganisms from bathers themselves, and (2) the type and concentration of etiological agent on the observed heterogeneity of the incidence of illness in epidemiological studies that have been used to develop ambient water quality criteria. The etiological agent and corresponding dose ingested during recreational contact was found to significantly impact the observed incidence of illness in an epidemiological study conducted in recreational water. In addition, the observed incidence of illness was found not to necessarily reflect background concentrations of indicator organisms, but rather microorganisms shed during recreational contact. Future revisions to ambient water quality criteria should address the etiological agent, dose, and the significance of microbial shedding relative to background concentrations of pathogens and indicator organisms in addition to the incidence of illness and concentration of indicator organisms. Without a quantitative assessment of these additional variables, study findings may potentially be site specific and not representative of the health risks associated with specific indicator concentrations in all recreational waters.  相似文献

This paper uses survey data to provide empirical evidence regarding the importance of positional concerns in different domains and their determinants. In the survey, respondents are asked to choose between a world in which they have more of a good than others and a world in which their endowment along with everyone else is greatly improved, but they have less than others. Our results lend support to the claim that positional concerns play a crucial role in the decision-making process of individuals, though they appear to be more influential in some domains than others. Moreover, empirical results point out relationships between the age, gender, education, and income level of the respondents and their positional concerns in different domains.  相似文献
