Abstract

Marguerite La Caze has recently published a stimulating analysis of the emotions of envy and resentment in which she argues that to envy others for a benefit they have received or to resent them for such a reason can be ethically acceptable in cases where that benefit has been unjustly obtained (La Caze, 2001). I question this on the ground that the judgement that the benefit has been unjustly obtained plays a more complex role in the structure of envy and resentment than La Caze allows and should alter the nature of the feeling that is evoked. From the perspective of virtue ethics there is nothing creditable about still feeling envy or resentment in such circumstances.  相似文献

This study sought to ascertain whether elevated emotional load and a lack of social support could be indicative of bullying at work. Participants totalled 1442 employees from the manufacturing industry in South Africa. Data on emotional load, social support, and bullying were gathered using a self-report survey. Structural equation modelling methods were implemented to establish the variance explained in bullying by colleagues and bullying by supervisors, as outcomes, with emotional load and social support as predictor variables. Additionally, multi-group analyses were performed to investigate how the explained variances might differ based on gender and race. Results revealed that the models fitted the data well and that emotional load and a lack of social support explained a substantial amount of variance in bullying by superiors and bullying by colleagues. With regard to the multi-group analysis more variance was explained for females than for males, but the values were quite similar in all groups which give strength to the generalisability of the findings. The findings of this study therefore indicate that elevated emotional load and a lack of social support are indicators of bullying behaviour at work.  相似文献

This paper examines whether previously suggested reasons for having children: economic, social and psychological values of child can be identified among a group of sub-Sahara women, and the extent to which a spiritual value of child can be identified on the basis of African's belief in ancestors and its influence on their daily lives. Two groups of Ghanaian mothers—270 women (mean age = 42.14 years) with adolescent-aged child and 264 mothers (mean age =31.41 years) with a young child—participated in the study. Exploratory factor analyses found mixed support for the existence of social and psychological values of child. Economic values of child could not be identified. However, spiritual values of child came out as a clear factor, and accounted for about 10% of the explained variance, albeit the explained valiance was less than that from social and psychological values of child. The implications of these for family planning in sub-Sahara Africa and for fighting HIV/AIDS are discussed.  相似文献

This study aimed to assess HIV knowledge, risk perception and risk behaviour of ex-offenders at risk of new infection and to compare them with the general population. A case-control interview study was conducted with conveniently sampled ex-offenders and persons with no history of incarceration in four countries (Canada, France, Ivory Coast, South Africa). The total sample included 232 participants with a mean age of 33.9 years (SD=9.8 years). Results indicate various high HIV risk behaviours including multiple sexual partners, irregular sexual partner, and commercial sexual partner. Other risk factors were unprotected sex at last intercourse with a regular partner, with an irregular partner and with a commercial sexual partner. A history of incarceration did not differentiate risk for infection. Younger age, coming from the Ivory Coast, and higher HIV risk perception were found to be associated with HIV risk behaviour. Prevention efforts should focus on education, promotion of safe sex and substance abuse treatment.  相似文献

The aim of this study was to explore the attitudes, beliefs and behaviours of school-going rural males in KwaZulu-Natal, South Africa on teenage pregnancy. Two methods of data collection were used, namely, a quantitative survey with a sample of 294 male youth from 10 schools. This was followed by focus group interviews with three groups, each comprising ten males, from three of the schools. Quantitative data examined self reported knowledge, behaviours, beliefs and attitudes of participants relating to teenage pregnancy. Qualitative data from the focus groups generated both an individual and ‘group think and provided insights into the relational construction of these beliefs and behaviours. Although the analysis revealed some mixed reactions, the majority response pointed to ‘dominant male-submissive female’ views of sexual relationships. Most participants supported the notion that the burden of pregnancy fell on the female, with males frequently denying paternity and criticizing females for careless sexual behaviour. Attributions for teenage pregnancy by boys are important for intervention to curtail impact on survivor girls.  相似文献

This study investigated the moderating role of substance abuse in the relationship between psychopathy and aggression among male prison inmates. Two hundred and sixty-seven male prison inmates from the Nigerian Prison Services were participants. The inmates were incarcerated for armed robbery (27.3%), theft (31.1%), murder (12.8%), rape/assault/child abuse (19.1%), burglary/arson (5.6%) and kidnapping (1.5%) in Enugu prisons, Nigeria. Their mean age was 28.32; SD = 5.53. Their length of time in prison ranges from 1 to 12 years, with a mean of 3.38 years. Participants responded to self-reported measures of aggression, psychopathy, and drug abuse. The result of the moderated regression analysis indicated substance abuse to moderate the relationship between primary psychopathy and verbal aggression, and between secondary psychopathy and hostility. The study findings underscore the importance of psychological intervention aimed at addressing aggression among prison inmates with histories of substance abuse and psychopathy.  相似文献

This study sought to determine whether Perceived Organisational Support for Strengths Use (POSSU) and Proactive Behaviour towards Strengths Use (PBSU) predict engagement and productivity in a sample of South African call centre operators. Participants were 218 call centre operators within the financial services sector (females=51%, males = 49%), representative of the South African population, and predominantly holding secondary educational qualifications. Information was gathered through a cross-sectional quantitative research design comprising self-report measures. The measures were administered on site within a call centre of one of the country's largest financial service providers. Structural equation modelling methods were implemented to establish the model fit of the constructs in the study and to explain structural paths between the variables. Findings showed that POSSU and PBSU are significant predictors of work engagement. PBSU predicted productivity. In addition, engagement mediated the relationship between POSSU/PBSU and productivity. This supports the theoretical context of the job demands-resources (JD-R) model and provides grounds for further exploration of the strengths-based approach (on both organisational and individual levels) as a developmental approach to utilise within organisations to enhance engagement and productivity.  相似文献

Lower levels of parent–child affective flexibility indicate risk for children's problem outcomes. This short‐term longitudinal study examined whether maternal depressive symptoms were related to lower levels of dyadic affective flexibility and positive affective content in mother–child problem‐solving interactions at age 3.5 years (N = 100) and whether these maternal and dyadic factors predicted child emotional negativity and behaviour problems at a 4‐month follow‐up. Dyadic flexibility and positive affect were measured using dynamic systems‐based modelling of second‐by‐second affective patterns during a mother–child problem‐solving task. Results showed that higher levels of maternal depressive symptoms were related to lower levels of dyadic affective flexibility, which predicted children's higher levels of negativity and behaviour problems as rated by teachers. Mothers' ratings of child negativity and behaviour problems were predicted by their own depressive symptoms and individual child factors, but not by dyadic flexibility. There were no effects of dyadic positive affect. Findings highlight the importance of studying patterns in real‐time dyadic parent–child interactions as potential mechanisms of risk in developmental psychopathology.

Prenatal and perinatal risk factors, such as low birth weight, have been linked to higher levels of aggressive and destructive behaviours during childhood. Although low birth weight is associated with childhood externalizing behaviour, the mechanisms underlying this relationship remain open to empirical investigation. The current study extends the current literature by examining whether verbal skills mediate the relationship between low birth weight and childhood externalizing behaviour. A longitudinal analysis of data from the Fragile Families and Child Well‐being Study reveals that verbal skills appear to mediate the influence of low birth weight on serious aggression and destructive behaviour at age 5. The implications of this research are discussed. Copyright © 2012 John Wiley & Sons, Ltd.  相似文献

A research synthesis was conducted with four studies which correlated national mean self-ratings of affect balance (positive minus negative affect) and subjective well-being with the nations' cultural characteristics (individualism, masculinity, uncertainty avoidance, and power-distance national scores on Hofstede's dimensions), socioeconomic development (Human Development Index), and climate (absolute latitude). A meta-analysis of these collective level cross-cultural studies shows that individualism correlates positively with affect balance and subjective well-being, controlling for socioeconomic development, cultural femininity, power-distance, uncertainty avoidance, and climate. Similar results were found for individual-level data. The meaning of collective-level or national means of individual self-reports of affect balance is discussed.  相似文献
