The present study investigated men’s experiences with their breast cancer diagnosis and post-mastectomy lives. It is based on the sociological tradition of investigating the “marginal man” who lives in two not merely different but incompatible cultures (e.g., the pink ribbon culture of breast cancer and the everyday ideals of masculinity and the male body). Seventeen mature and aging U.S. men who all lived with a breast cancer diagnosis and treatment, including a mastectomy, were interviewed. The principle finding reveals that they saw themselves as men and remain seen by others in terms of their gender, not their atypical illness. Two meta-themes underlying men’s breast cancer stories were identified: body talk and embodiment of their breast. Each of these themes had subthemes. Noticeable was how the historical era when diagnosed and men’s aging experiences influenced their illness journey and stories. For all, even the recently diagnosed, their journey was a lonely one. No man had known another man with breast cancer to consult. Only a few men felt their breast cancer was a stigma, and they too did not feel emasculated. Instead, in the process of embodying their breast cancer, they amended their identities and practiced softer, hybrid forms of masculinities.
Research has indicated that differential parental treatment is linked to differences in externalizing symptomology (EXT) across siblings, even those siblings who are genetically identical. However, the direction of causation and longitudinal significance of this relationship remains unclear. Thus, in the present study, the authors examined 486 monozygotic twin pairs, assessed at ages 11, 14, and 17 years, within a cross-lagged twin differences design. Results revealed that differential parent-child conflict at age 11 years uniquely contributed to differential sibling EXT 3 years later but only in the most discordant twin pairs. In the full, unselected sample, this relationship was not significant. These results suggest that markedly different parent-child conflict has an environmentally mediated impact on child behavior through mid-adolescence, findings that yield insights into environmental influences on behavior. 相似文献
We investigated the interaction between transient change in the local structure of gastrocnemius muscle fibers and the segmented leg motor responses elicited by toes-up rotation of the support surface. The gastrocnemius muscle in healthy young subjects underwent a sustained 2-min, isometric stretch (Prestretch group), followed immediately by the rotations. Analysis showed that the prestretch affected the amplitude of the monosynaptic but not the automatic components of the medial gastrocnemius muscle responses (monosynaptic response: 93 +/- 20% of the mean of the last three rotations in the Prestretch group compared to 174 +/- 42% in the Control group; automatic response: 128 +/- 18% in the Prestretch group versus 123 +/- 31% in the Control group). The shortened tibialis anterior muscle response and the onset latencies of responses were not affected by prestretching the gastrocnemius muscle. The prestretch effect on the amplitude of the monosynaptic (mediated by group Ia afferents) but not the automatic gastrocnemius muscle response (mediated by group II afferents) suggests that the automatic component of the muscle response to platform rotations has a stronger supraspinal influence than the monosynaptic response and is thus less affected by local events such as prolonged stretching. 相似文献
McDermott and Hauser have recently shown that although monkeys show some types of preferences for sound, preferences for music are found only in humans. This suggests that music might be a relatively recent adaptation in human evolution. Here, I focus on the research methods used by McDermott and Hauser, and consider the findings in relation to infancy research and music psychology. 相似文献
The hypothesis that parental alcoholism and co-occurring antisocial behavior would be indirectly linked to child externalizing behavior problems through child lack of control, current levels of parent depression, family conflict, and parent–child conflict was tested using manifest variable regression analysis. Participants were a community sample of 125 families with an alcoholic father and 83 ecologically matched but nonsubstance abusing families involved in the first 2 waves of an ongoing longitudinal study (with 3 years between each wave). All families had a biological son who was 3–5 years old at study onset. Results revealed that child lack of control mediated the relation between paternal alcoholism and the son's subsequent externalizing behavior problems. Family conflict was a significant mediator of maternal and paternal lifetime antisocial behavior effects and father–son conflict mediated paternal lifetime antisocial behavior effects. Study implications are discussed within the context of parental socialization of antisocial behavior. 相似文献
Increasing evidence indicates the importance of environmental variables in explaining physical activity. This study evaluated sex differences in perception of home and neighborhood environmental support and assessed which neighborhood environmental variables were associated with reported physical activity of elderly people. A sample of 126 women (M age = 79.1 +/- 6.6 yr.) and 55 men (M age = 76.6 +/- 7.7 yr.) were healthy, community-dwelling individuals. A questionnaire about environmental variables was administered. Physical activity was assessed on the Baecke Questionnaire. Logistic regression analysis showed that Neighborhood Safety was related to total physical activity, activity in leisure time, and sport activities. Men were also likely to be more active in leisure time than women. Neighborhood Personal Safety was associated with physical activity of these elderly people, showing a potential influence of the environmental domain in physical activity. 相似文献

The present study examined the influence of pharmacological modulations of the locus coeruleus noradrenergic system on odor recognition in the mouse. Mice exposed to a nonrewarded olfactory stimulation (training) were able to memorize this odor and to discriminate it from a new odor in a recall test performed 15 min later. At longer delays (30 or 60 min), the familiar odor was no longer retained, and both stimuli were perceived as new ones. Following a post-training injection of the alpha(2)-adrenoceptor antagonist dexefaroxan, the familiar odor was still remembered 30 min after training. In contrast, both the alpha(2)-adrenoceptor agonist UK 14304 and the noradrenergic neurotoxin DSP-4 prevented the recognition of the familiar odor 15 min after the first exposure. Noradrenaline release in the olfactory bulb, assessed by measurement of the extracellular noradrenaline metabolite normetanephrine, was increased by 62% following dexefaroxan injection, and was decreased by 38%-44% after treatment with UK 14304 and DSP-4. Performance of mice in the recall test was reduced by a post-training injection of the beta-adrenoceptor antagonist propranolol or the alpha(1)-antagonist prazosin, thus implicating a role for beta- and alpha(1)-adrenoceptors in the facilitating effects of noradrenaline on short-term olfactory recognition in this model. 相似文献
