Online social networking sites, such as Facebook, have provided a new platform for individuals to produce and reproduce gender through social interactions. New mothers, in particular, may use Facebook to practice behaviors that align with their mothering identity and meet broader societal expectations, or in other words, to “do motherhood.” Given that Facebook use may undermine well-being, it is important to understand the individual differences underlying new mothers’ experiences with Facebook during the stressful first months of parenthood. Using survey data from a sample of 127 new mothers with Facebook accounts residing in the U.S. Midwest, we addressed two key questions: (a) Are individual differences in new mothers’ psychological characteristics associated with their use and experiences of Facebook? and (b) Are new mothers’ psychological characteristics associated with greater risk for depressive symptoms via their use and experiences of Facebook? Regression analyses revealed that mothers who were more concerned with external validation of their identities as mothers and those who believed that society holds them to excessively high standards for parenting engaged in more frequent Facebook activity and also reported stronger emotional reactions to Facebook commentary. Moreover, mothers who were more concerned with external validation were more likely to have featured their child in their Facebook profile picture. Mediation analyses indicated that mothers who were more prone to seeking external validation for their mothering identity and perfectionistic about parenting experienced increases in depressive symptoms indirectly via greater Facebook activity.  相似文献

Traditionally, acts of civil disobedience are understood as a mechanism by which citizens may express dissatisfaction with a law of their country. That expression will typically be morally motivated, non-violent and aimed at changing their government’s policy, practice or law. Building on existing work, in this paper we explore the limits of one well-received definition of civil disobedience by considering the challenging case of the actions of animal activists at sea. Drawing on original interviews with advocates associated with Sea Shepherd, Greenpeace and Humane Society International we find that even if animal activists are morally motivated and civil, the transnational nature of their activity makes it difficult to assess their intention to bring about a change in law or public policy. This means that a civil disobedience defence may not be available to activists operating across international borders. This raises important questions about the usefulness of the civil disobedience concept within the context of a globalised world. We conclude that while the actions of some anti-whaling activists may not meet definitions of civil disobedience as conventionally understood, this says more about the narrow way in which that concept has been traditionally defined, than it does about the type of activity some anti-whaling activists have undertaken in the Southern Ocean. Finally, we argue that activists wishing to make a stand against whaling may have no choice but to act as global citizens because policy change within a single nation-state is unlikely to lead to the cessation of this inherently transnational activity.  相似文献

Prevalence of obesity has increased worldwide in the past 20 years, but it is not known whether this has resulted in increased numbers of young adults feeling overweight. This study evaluated weight self-perception in a large, multi-ethnic sample of 14-15 years old (n=4167) in London, UK as part of a longitudinal, school-based study of health behaviours. Weight perceptions were recorded on a simple scale from 'too thin' to 'too fat'. Results indicated that under-estimation was more common than over-estimation, with more than a quarter of overweight or obese adolescents unaware of their excess weight. Under-estimation was greatest among boys and ethnic minorities. It may be timely to reassess weight control advice given to adolescents.  相似文献

Previous studies reporting that gay individuals are in worse mental health than heterosexuals have typically employed young or mixed-age samples, ignoring the role of age. Mental health problems may show greater age-related improvement among gay than heterosexual men as indicated by the findings of the present study. In this study, the following indices of mental health are examined, and found to be comparable, among 86 heterosexual and 81 gay men aged 18–48: depression, suicidality, anger, anxiety, negative self-esteem, emotional instability, and lack of emotional responsiveness. Most indices show age-related effects among gay men, with less severe symptoms reported by older individuals. Among heterosexual men, effects of age are less widespread, although older men do report fewer symptoms of anger. Chronic shame and chronic guilt are related to mental health problems and a lessening in shame accounted, in part, for the age-related decline in depression among gay men. Different approaches to disclosing/concealing sexual identity are also linked with shame, guilt, and mental health among gay men.  相似文献

The utility of a warning to deter malingering on measures of personality and psychopathology was examined. Sixty‐seven first year psychology students were randomly assigned to one of three conditions: unwarned malingerers, warned malingerers, and controls. Participants in the two malingering groups were given a financial incentive to simulate believable psychological impairment. Warned malingerers received an additional warning that the tests could detect malingering and that detection would result in loss of course credit. Controls received standardized test instructions. It was hypothesized that the malingering incentive would be sufficient to induce malingering, but that a deterrence theory warning would have a subsequent deterrent effect. Between‐groups analyses indicated that the warning used in this study significantly altered test performance on the Personality Assessment Inventory (PAI) and revised Symptom Checklist 90 (SCL‐90‐R). Warned malingerers scored significantly lower (faked less) than unwarned malingerers on the majority of the psychopathology scales and frequently approximated control group performances. These results support the effectiveness of a warning to complement existing malingering detection methods. Copyright © 2009 John Wiley & Sons, Ltd.  相似文献
