Other-related concerns for justice are fundamental components of morality and interpersonal behaviors. In this paper, we investigated macro/cultural and micro/individual differences in justice concerns for others. More specifically, beneficiary sensitivity (BS) and observer sensitivity (OS) were compared across China as a typical collectivist society, and Germany and Russia as two individualistic societies. Individualism–collectivism was assumed to mediate the cultural variance of BS and OS. In Study 1, Chinese participants exhibited more BS but less OS compared to German participants. In Study 2, the Chinese participants exhibited more BS but not significantly different OS compared to Russian participants. Moreover, collectivism mediated this cultural difference in BS but not OS. In Study 3, collectivist participants identified according to their proposals in social value games exhibited more BS than did individualistic participants, while the two groups revealed no significant difference in OS. Taken together, our studies consistently show that higher collectivism both on the cultural and individual levels is related to BS but not to OS, suggesting that collectivist values make people sensitive to self-advantage in comparison to the suffering of others.  相似文献

Objectives

Explore Bayesian spatio-temporal methods to analyse local patterns of crime change over time at the small-area level through an application to property crime data in the Regional Municipality of York, Ontario, Canada.

Methods

This research represents the first application of Bayesian spatio-temporal modeling to crime trend analysis at a large map scale. The Bayesian model, fitted by Markov chain Monte Carlo simulation using WinBUGS, stabilized risk estimates in small (census dissemination) areas and controlled for spatial autocorrelation (through spatial random effects modeling), deprivation, and scarce data. It estimated (1) (linear) mean trend; (2) area-specific differential trends; and (3) (posterior) probabilities of area-specific differential trends differing from zero (i.e. away from the mean trend) for revealing locations of hot and cold spots.

Results

Property crime exhibited a declining mean trend across the study region from 2006 to 2007. Variation of area-specific trends was statistically significant, which was apparent from the map of (95 % credible interval) differential trends. Hot spots in the north and south west, and cold spots in the middle and east of the region were identified.

Conclusions

Bayesian spatio-temporal analysis contributes to a detailed understanding of small-area crime trends and risks. It estimates crime trend for each area as well as an overall mean trend. The new approach of identifying hot/cold spots through analysing and mapping probabilities of area-specific crime trends differing from the mean trend highlights specific locations where crime situation is deteriorating or improving over time. Future research should analyse trends over three or more periods (allowing for non-linear time trends) and associated (changing) local risk factors.  相似文献

Martha Nussbaum raised profound concerns about aid as being conceived out of the self-directed charity of donors and not the expressed concerns of those being aided. Even when the recipients of aid seek to express their concerns, their capabilities may not recognise their own conditions and desirable remedies. This paper agrees that Nussbaum’s questions are profound, but argues that even they do not go far enough.  相似文献

The number of Internet news media outlets has skyrocketed in recent years. We analyze the effects of media proliferation on electoral outcomes assuming voters may choose news that is too partisan, from an informational perspective, i.e., engage in partisan selective exposure. We find that if voters who prefer highly partisan news—either because they are truly ideologically extreme, or due to a tendency towards excessive selective exposure—are politically “important,” then proliferation is socially beneficial, as it makes these voters more likely to obtain informative news. Otherwise, proliferation still protects against very poor electoral outcomes that can occur when the number of outlets is small and the only media options are highly partisan. Our model’s overall implication is thus that, surprisingly, proliferation is socially beneficial regardless of the degree of selective exposure.  相似文献

When the Internet user keys a search term and clicks “enter”, a series of snippets, images and html links will appear typically running into several web pages. In the case of Autocomplete suggestions, the result appearing on the bar changes with each keystroke even before the user clicks “enter”. As a result, in the course of finding search results from the original search term, the user is constantly provided with suggestions of other search terms. The search results and Autocomplete suggestions may be defamatory of individuals and businesses by associating them with dishonest and improper activities or conduct. Should search engines be regarded as a publisher of such defamatory search results and/or Autocomplete suggestions? What is the appropriate legal approach for establishing search engine responsibility in such instances? The paper considers the above questions by reference to case precedents drawn primarily from common law jurisdictions and commentaries on the liability of search engines and other Internet intermediaries as well as policy rationales and considerations.  相似文献

Hepatic hemangiomas are usually detected incidentally when investigating for other nonrelated pathologies. When symptomatic, they are usually large and cause symptoms such as abdominal discomfort or other digestive issues. Occasionally, uncommon presentations such as bleeding with coagulopathy (Kasabach–Merritt syndrome) or even fever of unknown origin may occur. As hepatic hemangiomas are benign, they do not result in tumor emboli and pulmonary thromboembolism due to hepatic hemangiomas is extremely rare. This is a case report of a rare case of a female with no known past medical history who presented with sudden death due to pulmonary thromboembolism, possibly as a result of an underlying giant hepatic hemangioma. Incidentally, she also had three other tumors—pancreatic cystic lymphangioma, cerebral capillary telangiectasia, and papillary thyroid carcinoma, and their potential contribution to the cause of death will be discussed.  相似文献

This study investigated and compared the rates of child maltreatment as reported by parents and children. Self-reports of 1,093 children aged 12 to 18, which were matched with both parents’ records, were compared and analyzed in the study. The levels of agreement between parent and child reporting of various kinds of parental child maltreatment were low to moderate. Factors affecting the disagreement in reports were also investigated. Social desirability and violence approval were the common predictors of disagreement in father-child and mother-child reports, respectively. The low agreement between parent–child reports found in the present study highlights the need for the inclusion of both parent and child reports on maltreatment in future clinical screening and intervention programs.  相似文献

The present study developed the Child Abuse Risk Assessment Scale (CARAS), an actuarial instrument for the assessment of the risk of physical child abuse. Data of 2,363 Chinese parents (47.7% male) living in Hong Kong were used in the analyses. Participants were individually interviewed with a questionnaire assessing their perpetration of child abuse and some theoretically or empirically tested factors associated with child abuse. Using the split-half validation procedure, the 5-factor, 64-item CARAS was created and validated. When applying to the second half of the split sample, the CARAS had a sensitivity of 81.9%, a specificity of 77.8%, and an overall accuracy of 78.1%. The area under the receiver operating characteristic curve (AUC) was .91. Overall, our findings showed that the CARAS is a simple, systematic and validated instrument identifying at-risk population of child maltreatment in Chinese societies.  相似文献

Murders committed by juveniles remain a serious concern in the United States. Most studies on juvenile homicide offenders (JHOs) have used small samples and have concentrated on male offenders. As a result, little is known about female JHOs and how they differ from their male counterparts on a national level. This study utilized the Supplementary Homicide Report (SHR) database to examine more than 40,000 murders committed by male and female juvenile offenders from 1976 to 2005. This research effort, the most expansive to date, replicated previous findings with respect to gender differences using bivariate and multivariate analyses. As predicted, six variables used to test eight hypotheses with respect to male and female JHOs in single-victim incidents were significant (victim age, victim-offender relationship, murder weapon, offender count, victim gender, and homicide circumstance). Regression analysis revealed that all variables remained significant when entered into the model. This article concludes with a discussion of our findings and directions for future research.  相似文献
