This paper provides sufficient conditions under which the preferences of a social decision maker accord with majority voting. We show that an additive and monotone utilitarian social evaluation function is consistent with the outcomes of majority voting for the class of income distributions that are symmetric under a strictly increasing transformation. An example is the lognormal distribution. The required symmetry condition is generally accepted employing panel data for 116 countries from the World Bank’s POVCAL database.In this manner, the proposed methodology provides the consistent degree of inequality aversion and shows that median income is a good proxy for welfare.  相似文献

This paper explores the emotion of disappointment in organizations and develops a new line of theorizing inspired by psychoanalytic object‐relations theory. Existing literature frames disappointment as a threat to organizational effectiveness, as both a response and an anticipation of failure and as an emotion that needs to be managed in order to prevent it from damaging organizational morale and performance. This only captures part of the complexity of disappointment and leaves unexplored its potential contribution to organizational and individual learning and even creativity. The paper develops a theoretical framework which depicts disappointment in three configurations or positions, and it establishes the potential of disappointment acting as an integrative emotion within organizations. The framework accounts for an apparent contradiction in organizational members' experience of disappointment – that it is, at the same time, seen as ‘of little concern’ to individuals, and yet viewed as capable of undermining stability and destroying positive feelings. The paper shows how disappointment is connected to the dynamics of blame in organizations but, when fully appreciated, can offer a way of moving beyond these dynamics by recognizing partial failure within an organization and turning it into the basis for organizational learning.  相似文献

Research indicates that individuals high in belief in a just world (BJW) are confident that they will not fall victim to unforeseeable disasters. The current study tested the hypothesis that BJW acts as buffer that serves to sustain mood and career prospects of those in need of risk protection. Threat was manipulated by confronting participants with risks regarding their career outlook, and individual differences in threat perception were measured by degree of uncertainty tolerance. As hypothesized, BJW helped protect the mood of participants threatened by serious career‐related risks who were unable to tolerate uncertainty. The finding supported the buffer hypothesis regarding mood, but not career prospects, possibly due to a more conscious mindset or variability in self‐efficacy. However, BJW was overall positively associated with career prospects. Moreover, it was suggested that BJW can also serve as a personal resource, not only protecting from risk, but also enhancing mood among those with high uncertainty tolerance.  相似文献

Aim

To examine foot posture changes during the three trimesters of pregnancy and to determine whether there is a relationship between these changes and the pain experienced in this period.

Methods

The study sample consisted of 62 pregnant women who attended the Gynaecology Service at Hospital ?Santa María del Puerto (Cádiz, Spain), between January 2013 and May 2014. In their first visit, the following sociodemographic and anthropometric data were recorded: age, weight, height and foot size. In addition, information was obtained regarding pain in the lower back, knees, ankles and feet. In this first visit, too, the Foot Posture Index (FPI) was assessed, and three subsequent controls were performed during the first, second and third months of pregnancy (termed Stages 1, 2 and 3, respectively).

Results

In Stage 1, the average foot size (i.e., shoe size) was 38.3 (SD 1.5). This size did not change between Stages 1, 2 and 3. However, body weight and BMI did present statistically significant changes during this period (p < 0.0001). The FPI varied during pregnancy but no relation was observed between these changes and the onset of pain.

Conclusions

During pregnancy, pronation increases but this does not appear to influence the onset of pain in the lower limbs.  相似文献

This study examined the relationships between perceived loneliness, self-efficacy, and subjective well-being as related to students’ experiences as victims of cyber and face-to-face bullying. Participants included 902 students from 18 different Israeli schools, aged 10–18 who completed self-report questionnaires. Results revealed that social loneliness fully affects the experience of cyberbullying through the mediation of well-being. Greater social loneliness decreases the perception of well-being and therefore the probability of cybervictimization increases. Furthermore, social efficacy increases personal well-being, which decreases the likelihood of experiencing cyberbullying. In addition, students experiencing social and emotional loneliness were more likely to be victims of cyber- and face-to-face bullying than students who were not lonely. Age was found to be an overall indicator for the probability of exposure to bullying and being a victim. The current findings suggested that boys who are more socially effective perceive their well-being higher than girls, and these higher perceptions lead them to a higher immunity to, or a lower experience of cyber bullying. This indirect effect is fully operated through the mediators. Boys experience greater social and emotional loneliness than girls, but perceive their well-being more highly than girls. Boys also experience more face-to-face victimization, but not more cybervictimization compared to girls.  相似文献

This paper makes a contribution to the study of emotions in organizations by offering a systematic juxtaposition and cross-fertilization of psychoanalytic and social constructionist approaches. These two traditions have found it hard to communicate in the past when addressing organizational emotions. Points of similarity and tension between them are discussed in connection with two critical case studies of female Indian managers discussing their emotions at the workplace. These were obtained during field work in which emotions were studied through narratives generated by a free-association interview approach. Both the emotions described in the narratives themselves and the emotions of the interview encounter were analysed, as resources for a rapprochement of contrasting perspectives on emotion. This rapprochement acknowledges the psychoanalytic emphasis on unconscious dynamics shaping the emotional lives of individuals and groups, while also honouring the social constructionist emphasis on how emotions are influenced by social, cultural and discursive practices.  相似文献

Background

Reduced hip muscle strength has been shown to be a major factor related to falls in older persons. However, comprehensive assessment of hip abduction strength in the clinical setting is challenging. The aim of this study was to investigate the feasibility and intra-rater reliability of a quick and simple hip abductor strength test in a functional standing position.

Methods

Individuals over 65 years of age were recruited from the geriatric department of a university hospital and an outpatient clinic. Thirty-two older subjects, including 16 fallers (≥1 fall during the last 12 months) and 16 non-fallers were included. Maximum voluntary isometric strength (MVIS) and rate of force generation (RFG) of the hip abductors of the right leg were evaluated in a standing position using a hand-held dynamometer. Two test-sessions were carried out. All hip strength values were normalized to participants’ weight. Reliability was determined using the intra-class correlation coefficient agreement (ICCagreement), the standard error of measurement (SEM) and a Bland and Altman analysis (BA).

Results

All participants completed the strength tests, which took a mean 2.47?±?0.49 min (one limb). Intra-rater reliability was higher for MVIS (0.98[0.95–0.99]) than RFG (ICC?=?0.93[0.87–0.97]) for the entire sample. In the non-fallers, ICC was 0.98[0.95–1.00] (SEM?=?0.08 N.kg??1) for MVIS and 0.88[0.75–0.96] for RFG (SEM?=?1.34 N.kg-1.s-1). In the fallers, ICC was 0.94[0.89–0.98] (SEM?=?0.11 N.kg??1) for MVIS and 0.93[0.84–0.98] (SEM?=?1.12 N.kg??1.s??1) for RFG. The BA plot showed that the MVIS and RFG values did not differ across test-sessions, showing that no learning effect occurred (no systematic effect). The mean differences between test-sessions were larger and the LOA smaller in the fallers than in the non-fallers.

Conclusion

Assessment of hip strength in a standing position is feasible, rapid and reliable. We therefore recommend this position for clinical practice. Future studies should investigate the diagnostic value of hip abductor strength in standing to discriminate between fallers and non-fallers, and to determine if change in strength following a falls prevention program reduces the risk of falls.

We determine, by means of max-*-transitivity, necessary and sufficient conditions for a fuzzy binary relation R defined on a countable (finite or denumerable) set A to be representable by a utility function. We display one example of its application. The first author thanks AUF (Agence Universitaire de la Francophonie). This paper was revised when he was Visiting Researcher at CREM-University of Caen under the Research grant “Bourse Post-doctorale de la Francophonie 2005–2006”.  相似文献

The “Strength of Weak Ties” theory is used to analyze the flow of information and influence in the network of conversational ties in a kibbutz community.The flow of six information items and two decision-making items was measured by indicators of communicative efficiency — speed, accuracy and credibility. The strength of ties activated and the direction of the flow (within groups or between groups) was analyzed.The findings reveal the actual, everyday functioning of weak ties as inter-group bridges, confirming the “Strength of Weak Ties” claim.The communicative advantages of weak ties are examined, applying structural analysis methods. The tendency of weak ties towards intransitivity and low multiplexity, is suggested to account for their frequent activation as inter-group bridges.The findings highlight the potential of social network analysis as a bridge between micro-level interaction and macro-level patterns including diffusion of innovation, formation of public opinion and social solidarity. Weak ties serve as the crucial paths between groups, thus providing the means by which individual behavior and ideas, originating in small face-to-face groups, are routinized and agglomerated into large-scale patterns.  相似文献

The aim of this paper is to compare the relative performance of several tests for the null hypothesis of cointegration, in terms of size and power in finite samples. This is carried out using Monte Carlo simulations for a range of plausible data-generating processes. We also analyze the impact on size and power of choosing different procedures to estimate the long run variance of the errors. We found that the parametrically adjusted test of McCabe et al. (1997) is the most well-balanced test, displaying good power and relatively few size distortions.  相似文献
