Societal Risk Perception Among African Villagers Without Access to the Media

The impact of the media on people's risk perception was assessed by comparing risk ratings obtained from African villagers without access to the media with risk ratings obtained from African city-dwellers with access to the media and risk ratings obtained from French participants. The overall mean risk judgment observed among the Togolese villagers was lower than the mean rating observed among the Togolese city-dwellers, and lower than the mean rating observed among the French. The linear association observed between the Togolese villagers' ratings and the Togolese city-dweller ratings and the French ratings was moderate. The impact of the media on risk perception was estimated to be an increase of about 15% of the overall mean ratings, and to about 31% of the variance of the mean ratings. This impact was independent of educational level.     

Societal Risk Perception and Media Coverage

The study compares societal risk ratings by inhabitants of two countries which differ markedly in terms of geography, economics, politics, and ethnic background, but which are similar as regards media coverage. The two populations were represented by a sample of French students and a sample of Burkina Faso intellectuals. The overall Burkinabè mean ratings appeared much closer to the mean observed in France (and in the United States–roughly 40 out of 100) than the means reported for other countries like Norway or Hungary. The correlation between Burkinabè and French ratings was very high:.852. The findings argue in favor of a practically totally determinant effect of the media in risk perception.     

Some Limitations of Qualitative Risk Rating Systems

Qualitative systems for rating animal antimicrobial risks using ordered categorical labels such as “high,”“medium,” and “low” can potentially simplify risk assessment input requirements used to inform risk management decisions. But do they improve decisions? This article compares the results of qualitative and quantitative risk assessment systems and establishes some theoretical limitations on the extent to which they are compatible. In general, qualitative risk rating systems satisfying conditions found in real‐world rating systems and guidance documents and proposed as reasonable make two types of errors: (1) Reversed rankings, i.e., assigning higher qualitative risk ratings to situations that have lower quantitative risks; and (2) Uninformative ratings, e.g., frequently assigning the most severe qualitative risk label (such as “high”) to situations with arbitrarily small quantitative risks and assigning the same ratings to risks that differ by many orders of magnitude. Therefore, despite their appealing consensus‐building properties, flexibility, and appearance of thoughtful process in input requirements, qualitative rating systems as currently proposed often do not provide sufficient information to discriminate accurately between quantitatively small and quantitatively large risks. The value of information (VOI) that they provide for improving risk management decisions can be zero if most risks are small but a few are large, since qualitative ratings may then be unable to confidently distinguish the large risks from the small. These limitations suggest that it is important to continue to develop and apply practical quantitative risk assessment methods, since qualitative ones are often unreliable.     

基于在线评级和评论的评价者效用机制研究

互联网中对产品和服务的评价越来越受到重视,因为评价能够消除消费者的不确定性,辅助其做出购买决策。大多数在线购物网站中用户的评价包括评级和评论。现有的评价反馈系统和评价研究往往只单独关注评价者之间的评级或评论,而忽略了两者之间的有机统一。评价者的评级并不一定反映评价者的真实评价,很多评价者更倾向于选择评论文本来表达自己的真实情感。本文以从淘宝网抓取的852071条评价数据为基础,通过分析评价者评级和评论之间的不一致性,结合RFM模型,考虑评级和评论两种信息形成的评价效用,提出了RFMA模型来计算评价者的总体评价效用。并据此对好的与不好的评价者进行区分,进一步为消费者的购买决策提供支持。通过对评价者的总体分析可以得出,本文提出的机制更加具有可用性和有效性。     

Perception of Mobile Phone and Base Station Risks

Perceptions of risks associated with mobile phones, base stations, and other sources of electromagnetic fields (EMF) were examined. Data from a telephone survey conducted in the German- and French-speaking parts of Switzerland are presented (N = 1,015). Participants assessed both risks and benefits associated with nine different sources of EMF. Trust in the authorities regulating these hazards was assessed as well. In addition, participants answered a set of questions related to attitudes toward EMF and toward mobile phone base stations. According to respondents' assessments, high-voltage transmission lines are the most risky source of EMF. Mobile phones and mobile phone base stations received lower risk ratings. Results showed that trust in authorities was positively associated with perceived benefits and negatively associated with perceived risks. People who use their mobile phones frequently perceived lower risks and higher benefits than people who use their mobile phones infrequently. People who believed they lived close to a base station did not significantly differ in their level of risks associated with mobile phone base stations from people who did not believe they lived close to a base station. Regarding risk regulation, a majority of participants were in favor of fixing limiting values based on the worst-case scenario. Correlations suggest that belief in paranormal phenomena is related to level of perceived risks associated with EMF. Furthermore, people who believed that most chemical substances cause cancer also worried more about EMF than people who did not believe that chemical substances are that harmful. Practical implications of the results are discussed.     

Insularity and Governance: The Case of French Polynesia

Insularity, smallness and remoteness help explain specific tendencies noted in the governance of French Polynesia, a partially self-governing French overseas territory in the South Pacific, with a population of 220,000. Professional relations tend to become personalized, and impersonal and impartial procedures are hard to apply. The market for experts is small: some people are able to claim a monopoly on some type of expertise and then defend it by every means. Solidarity is vertical, not horizontal, which makes for a fragile democracy.     

The Primary Importance of Corporate Social Responsibility and Ethicality in Corporate Reputation: An Empirical Study

We examine three assumptions commonly held in the corporate reputation literature: (1) reputation ratings of owners and investors are generally representative of all stakeholders; (2) stakeholders will generally provide a higher reputation rating to firms that emphasize corporate social responsibility versus firms that do not; and (3) profitability is the primary criterion of importance to all stakeholders when rating a firm's reputation. Using an exploratory in‐class exercise, our findings suggest that: (1) there are significant differences among stakeholder groups in their reputation ratings; (2) firms that emphasize corporate social responsibility are not rated more highly across all stakeholder groups; and (3) for all stakeholder groups, the ethicality criterion explained more of the variance in firms' reputation ratings than the profitability criterion.     

Toward ‘mental accessibility’: changing the mental obstacles that future Human Resource Management practitioners have about the employment of people with disabilities

This paper presents the results of a participatory research project undertaken with Hungarian MSc students specializing in Human Resource Management and Development about the employment of people with disabilities. The unemployment rate for people with disabilities is very high in Hungary and HR practitioners have a key role in maintaining or reducing barriers to their employment. Following the tradition of critical pedagogy, the aim of the research project was twofold. Firstly, we aimed to reveal the mental patterns, attitudes and beliefs of future HR practitioners to the employment of people with disabilities (which might be root causes of domination, discrimination or exploitation). Secondly, through using a radical methodological approach – cooperative inquiry – the researchers wished to emancipate students and challenge their frozen beliefs about disability as well as the positivist value system which usually dominates business education. The main result of the research project was to challenge the medical approach to disability which formerly dominated the belief systems of our student co-researchers, thereby engendering a more critical worldview.     

An international study of ethics

This study presents the results of a survey of graduate students from three cultural backgrounds. English, German, and American business students responded to an eleven-item survey designed to assess one's beliefs about what is necessary to succeed in graduate business programs. The results indicate that the attributes which students believe are required to succeed differ among cultures, with the greatest differences occurring between the American and European respondents.     

The Association of Knowledge with Concern About Global Warming: Trusted Information Sources Shape Public Thinking

During the last decade, a great deal of news media attention has focused on informing the American public about scientific findings on global warming (GW). Has learning this sort of information led the American public to become more concerned about GW? Using data from two surveys of nationally representative samples of American adults, this article shows that the relation between self‐reported knowledge and concern about GW is more complex than what previous research has suggested. Among people who trust scientists to provide reliable information about the environment and among Democrats and Independents, increased knowledge has been associated with increased concern. But among people who are skeptical about scientists and among Republicans more knowledge was generally not associated with greater concern. The association of knowledge with concern among Democrats and Independents who trust scientists was mediated by perceptions of consensus among scientists about GW's existence and by perceptions that humans are a principal cause of GW. Moreover, additional analyses of panel survey data produced findings consistent with the notion that more knowledge yields more concern among Democrats and Independents, but not among Republicans. Thus, when studying the relation of knowledge and concern, it is important to take into account the content of the information that different types of people acquire and choose to rely upon.     

Cognitive Components of Risk Ratings

This study examined what lay people mean when they judge the "risk" of activities that involve the potential for accidental fatalities (e.g., hang gliding, living near a nuclear reactor). A sample of German and American students rated the "overall risk" of 14 such activities and provided 3 fatality estimates: the number of fatalities in an "average year," the individual yearly fatality probability (or odds), and the number of fatalities in a "disastrous accident." Subjects' fatality estimates were reasonably accurate and only moderately influenced by attitudes towards nuclear energy. Individual fatality probability correlated most highly with intuitive risk ratings. Disaster estimates correlated positively with risk ratings for those activities that had a low fatality probability and a relatively high disaster potential. Annual average fatality rates did not correlate with risk ratings at all. These findings were interpreted in terms of a two-dimensional cognitive structure. Subjective notions of risk were determined primarily by the personal chance of death; for some activities, "disaster potential" played a secondary role in shaping risk perception.

Facts and myths about suicide: a study of Jewish and Arab students in Israel

This research investigates the knowledge and myths regarding suicide among students in Israel, and examines whether they are affected by ethnic origin, gender, and religiosity. A random sample of 450 undergraduate students from two colleges was asked to fill out the Suicide Opinion Questionnaire (SOQ). Knowledge was measured by five SOQ items (alpha = 0.57) and myths of suicide by 20 SOQ items (alpha = 0.67). The level of Israeli students' knowledge about suicide is generally good (X = 3.21; SD = 0.58). There are significant differences, however, between the Jewish (n = 266) and Arab (n = 154) students in knowledge about basic facts of suicide in Israel [(X Arabs = 3.04; X Jews = 3.32; t (419, 0.95) = 4.63, p < .001)]. Although both groups share the same educational milieu, the Arab students tend more to believe that suicide rates are higher in Israel, and even more so among people of Asian African origin and minorities. They also perceive suicide by shooting to be the most popular suicide method. There are also significant differences between those groups with respect to their belief in suicide myths [(X Arabs = 2.91; SD = 0.40; X Jews = 3.17, SD = 0.41; t (419, 0.95)= 6.31, p < 0.01)]. Arabs tend more to relate suicide to lower religious affiliation, mental illness and chronic tendency, and to believe that the victim's relatives know nothing about the coming suicide. No significant differences were found based on religiosity or gender. Discussion focuses on the influence of the different cultural characteristics of lifestyle and the social control systems among Jews and Arabs in Israel on perceptions toward suicide.     

Comparison of the Effects of Specific and General Performance Standards on Performance Appraisal Decisions*

This study compares specific and general performance standards as managerial decision aids. Sixty-four federal government comptrollers familiar with performance standards as a basis for judging performance evaluated five performance profiles and then assigned performance ratings. These profiles varied in levels of objective performance, prior performance, and the order in which they were evaluated. The results show that the specificity of performance standards moderates the relationship between objective and rated performance, with specific standards resulting in more accurate ratings than general standards. While objective performance was the most important determinant of performance rating, the gender of the rater, the order of evaluation, and prior performance ratings biased judgments in the general but not the specific performance standard condition. Specific performance standards are concluded to be useful decision aids that minimize performance rating bias and have potential as evaluation tools for groups, profit centers, organizations, and technology innovations.     

Changes in Management Practice and the Post-Acquisition Performance Achieved by Direct Investors in the UK

Changes in the competitive performance of 201 UK firms acquired by foreign investors are examined. Performance improvement was found to be associated with the introduction of changes to management practice rather than with contextual factors such as acquirer nationality, size, date of acquisition, profitability of subsidiary at acquisition or sector. The changes having most impact were increased efforts to improve the market image of the acquired company, the development of new products and services, and moves towards involving and developing staff. There appears to be more than one path towards post-acquisition performance improvement, with distinctions emerging between Anglo-American, Japanese and, to a lesser extent, French approaches. The successful Anglo-American approach involves a product innovation strategy, increased decentralization and improved training. High-performing Japanese acquisitions tend to emphasize a price-competitive strategy, to increase centralization and to adopt a longer-term HRM policy. The French path towards good post-acquisition performance includes increased cost control, more open communication and decentralization. The general conclusion of the investigation is that foreign acquisition can harness the assets and competencies of UK companies to good effect, but that there is more than one way of achieving this result.     

Further Thoughts on the Utility of Risk Matrices

Risk matrices are commonly encountered devices for rating hazards in numerous areas of risk management. Part of their popularity is predicated on their apparent simplicity and transparency. Recent research, however, has identified serious mathematical defects and inconsistencies. This article further examines the reliability and utility of risk matrices for ranking hazards, specifically in the context of public leisure activities including travel. We find that (1) different risk assessors may assign vastly different ratings to the same hazard, (2) even following lengthy reflection and learning scatter remains high, and (3) the underlying drivers of disparate ratings relate to fundamentally different worldviews, beliefs, and a panoply of psychosocial factors that are seldom explicitly acknowledged. It appears that risk matrices when used in this context may be creating no more than an artificial and even untrustworthy picture of the relative importance of hazards, which may be of little or no benefit to those trying to manage risk effectively and rationally.     

Self–other agreement in empowering leadership: Relationships with leader effectiveness and subordinates' job satisfaction and turnover intention

We investigated the effect of self–other agreement in empowering leadership on leader effectiveness, job satisfaction, and turnover intention using a sample of 50 Norwegian municipal leaders (46 for leader effectiveness) and 168 (158) of their subordinates. The findings indicated that considering both self and subordinate ratings of empowering leadership was useful in predicting the outcome variables. In particular, subordinates of over-estimators reported lower job satisfaction and higher turnover intention. Moreover, leaders who underestimated their leadership were perceived as more effective by their superiors. For agreement (i.e., leader's self-ratings were in agreement with subordinates' ratings) the relationship between empowering leadership and leader effectiveness was curvilinear with an inverted U shape. Agreement in ratings of empowering leadership was not found to be related to subordinates' job satisfaction and turnover intention. The implications of these findings are discussed.     

Quantitative Uncertainty Analysis for a Weed Risk Assessment System

Weed risk assessments (WRA) are used to identify plant invaders before introduction. Unfortunately, very few incorporate uncertainty ratings or evaluate the effects of uncertainty, a fundamental risk component. We developed a probabilistic model to quantitatively evaluate the effects of uncertainty on the outcomes of a question‐based WRA tool for the United States. In our tool, the uncertainty of each response is rated as Negligible, Low, Moderate, or High. We developed the model by specifying the likelihood of a response changing for each uncertainty rating. The simulations determine if responses change, select new responses, and sum the scores to determine the risk rating. The simulated scores reveal potential variation in WRA risk ratings. In testing with 204 species assessments, the ranges of simulated risk scores increased with greater uncertainty, and analyses for most species produced simulated risk ratings that differed from the baseline WRA rating. Still, the most frequent simulated rating matched the baseline rating for every High Risk species, and for 87% of all tested species. The remaining 13% primarily involved ambiguous Low Risk results. Changing final ratings based on the uncertainty analysis results was not justified here because accuracy (match between WRA tool and known risk rating) did not improve. Detailed analyses of three species assessments indicate that assessment uncertainty may be best reduced by obtaining evidence for unanswered questions, rather than obtaining additional evidence for questions with responses. This analysis represents an advance in interpreting WRA results, and has enhanced our regulation and management of potential weed species.     

Do you remember? Rater memory systems and leadership measurement

Despite widespread concerns about the use of retrospective accounts of leader behavior and response tendencies associated with raters who tend to rely on semantic memory, little attention has been devoted to developing methods that move measurement processes beyond those based on semantic memory to those based on episodic memory. The results from a series of six studies demonstrate a) questionnaire items can be classified in terms of their emphasis on episodic or semantic memory and the language used in items is associated with different types of memory processes, b) scales based on episodic memory have a greater association with trust than do scales based on semantic memory, c) the procedure that requires raters to indicate whether their response to each item is based on semantic or episodic memory dramatically reduces the impact of liking on leadership ratings, and d) the memory source intervention that encourages raters to rely on episodic memory reduces false alarms in leadership ratings. Taken together, these results demonstrate that rater memory systems are an important component of the leadership rating process and that consideration of the type of memory elicited during that process can be used to improve leadership measurement.     

利益关联、评级资格管制与基金评级公正性

具有基金评级资格的证券公司与证券投资基金之间存在着紧密而有趣的经济关系,一方面,具有基金评级资格的证券公司可以对基金进行评级,另一方面,基金与证券公司之间可能存在利益关联,具体体现在:1)基金要通过证券公司的交易席位进行交易并相应地给予证券公司交易佣金;2)证券公司可能是投资基金的大股东.那么这两种利益关联会损害证券公司作为基金评级机构的公正性吗？研究发现:1)如果证券公司与投资基金之间存在交易佣金关系或股权关系,那么证券公司会显著提高基金的评级等级;2)通过利益关联获得的基金评级对基金未来业绩解释力明显较低;3)2010年实施基金评价资格管制之后,上述两种现象更为明显.综合研究结果表明,利益关联会损害证券公司作为基金评级机构的公正性,且基金评级资格管制可能进一步加剧了利益关联对评级公正性的损害.
