This paper presents empirical research which demonstrates how snacks brands can satisfy certain personal values for female 11–12 year‐old British and Spanish consumers. The qualitative research design uses a means‐end approach, based on a laddering technique, to uncover the links between brand choice and personal values. After reviewing the means‐end model and other relevant theory, the research methodology and design are presented in detail. The findings reveal significant scope for positioning snacks brands using the values of well being and fun and enjoyment (UK and Spain), while the value of friendship and belonging emerges as an extra dimension for the British respondents.

The purpose of this study was to evaluate whether the impact of financial strain on psychological distress depends on the value that older adults place on economic success. Feelings of personal control were specified as an intervening variable in this process. The data came from a nationwide survey of 819 people in Canada who were 55 years of age and older. The findings reveal that financial problems are associated with diminished feelings of control and that these effects are stronger when elderly people value economic achievement highly. In addition, financial strain and diminished feelings of control are related to increased distress regardless of how highly economic success is valued. 相似文献

We distinguish and review aspects of the history of two models of triage: egalitarian and utilitarian. Egalitarian triage is widely and successfully practiced in battlefield medicine, as well as in the emergency room and the ICU. Utilitarian triage has been sporadically practiced and typically collapses under the pressure of public scrutiny. Unfortunately, the two models tend to be conflated, confusing our understanding of the past and confounding our ability to plan for the future. 相似文献

The present study sought to extend our knowledge of dysphoric adolescents' dyadic peer interactions. Thirty female dyads (ages 13–17) were videotaped interacting during both a structured and an unstructured task. Fourteen of the dyads were each comprised of a dysphoric girl and a nondysphoric girl; the remaining dyads were comprised of two nondysphoric girls. Girls were considered dysphoric if they scored 10 or higher on the Beck Depression Inventory. Dysphoric subjects evaluated their performances more negatively than nondysphoric subjects and rated their partners more negatively overall. The partners of the dysphoric girls were viewed by raters as less positive and less happy. They saw the dysphoric teens as making more critical comments and evaluated them more negatively overall. There was also a tendency for these girls to reject their dysphoric partners and to become more passive during the unstructured task. The findings indicate that dysphoric adolescent girls evoke negative reactions from peers and negatively influence their peers' behavior. These negative reactions from others may lead to further difficulties in negotiating the developmental tasks of adolescence. 相似文献

The effects of selective cholinergic cell loss within the basal forebrain (BF) were determined using a task that requires shifting of attention between two visual stimuli. Discriminability between two stimuli and response bias were determined in young and old F-344 rats given BF injections of IgG-192 saporin (100 ng). The lesion reduced ChAT activity in the frontal and parietal cortices, hippocampus, and olfactory bulbs. The lesion did not significantly alter Na+/K+-ATPase activity in cortex, hippocampus, or olfactory bulbs, or endogenous levels of neuropeptide Y and neurokinin B within the BF. The BF lesions impaired both stimulus discriminability and response bias in young and old rats. The BF lesions had a significantly greater effect upon stimulus discriminability and response bias in aged rats, compared to young rats, only when the stimulus duration was very brief, i.e., when the task was most difficult to solve. At longer stimulus durations, aging and lesions showed no interaction. The results suggest that the selective loss of cholinergic cells in the BF, but not normal aging, impairs the ability to discriminate between independent sensory stimuli. The loss of these cells confers a response bias in simple operant tasks involving motor responses to reward-related visual stimuli. 相似文献

Abstract— In recent years, theoretical models of drug motivation and drug dependence have downplayed the role of withdrawal symptoms in the maintenance of addiction. During this same period, strong links between drug use and measures of negative affect have been uncovered in empirical research. In this article we examine these trends in the context of research on smoking. Evidence is presented from two recent studies on smoking relapse that highlight the intimate connection between withdrawal symptomatology and negative affect Specifically, these studies reveal that (a) single-occasion measures of withdrawal symptoms or other markers of physical dependence do not contribute incremental validity in preceding relapse relative to measures of negative affect (b) the trajectory of withdrawal symptoms is highly idiosyncratic, (c) exacerbations cannot be tightly coupled with pharmacological events. (d) the temporal dynamics of withdrawal reflect fluctuations in negative affect, and (e) differences in the trajectory of withdrawal symptoms index relapse vulnerability. We conclude that a broadened view of withdrawal recognizing its probable affective bases will enhance its explanatory power and suggest new treatment strategies. 相似文献
