Varying risk factors for both incarceration and mental health diagnoses have been identified for female juveniles, highlighting the need for gender-specific assessments and treatment protocols. The purpose of this study is to determine how the prevalence rates of mental health symptoms differ in male and female juvenile offenders. It was hypothesized that the prevalence rates would be greater for females than males. This study found significant differences between males and females on several clinical scales. These findings are consistent with past studies that have identified differences in mental health symptoms between genders. 相似文献

Over the past decade, increasing attention has been paid to gender‐related consumption behaviour. However, a relative gap in our knowledge still exists when it comes to understanding the changes that occur as a result of motherhood and how this may influence their interactions in the retail environment. The purpose of this article is to explore stay‐at‐home mothers’ experiences in the servicescape to gain a better understanding of how they associate with servicescapes during this transitional period, how they use retail space to suit their needs, and how they use retail space to negotiate their role as a stay‐at‐home mother. Five stay‐at‐home mothers with children younger than 5 years were provided with disposable cameras and asked to photograph servicescapes that they visited regularly. Over a 1‐year period, they were interviewed several times, and photo‐elicitation techniques were used throughout the interviewing process. The results of this study suggest that when consumers undergo role or identity changes, certain places can be used to smooth this process. Not only can the retail environment be used as a coping mechanism for stay‐at‐home mothers, it can also be viewed as a “second place” as opposed to a “third place”, thus enabling isolated consumers to feel connected with the outside world. Last, this study highlights the temporal dimensions of place. Throughout one's lifetime, one will form attachments to and patronise different places, which will evolve and change as individuals, accordingly, take on different roles and identities.

One aim of this study was to apply information theoretical analyses to understanding the structural complexity of chick-a-dee calls of Carolina chickadees, Poecile carolinensis. A second aim of this study was to compare this structural complexity to that of the calls of black-capped chickadees, P. atricapillus, described in an earlier published report (Hailman, Ficken, & Ficken, 1985). Chick-a-dee calls were recorded from Carolina chickadees in a naturalistic observation study in eastern Tennessee. Calls were analyzed using approaches from information theory, including transition probability matrices, Zipf's rules, entropies, and information coding capacities of calls and notes of calls. As described for black-capped chickadees, calls of Carolina chickadees exhibited considerable structural complexity. Most results suggested that the call of Carolina chickadees is more structurally complex than that of black-capped chickadees. These findings add support to the growing literature on the complexity of this call system in Paridae species. Furthermore, these results point to the feasibility of detailed cross-species comparative analyses that may allow strong testing of hypotheses regarding signal evolution. 相似文献

Five experiments tested the hypothesis that there is a bi-directional link between ideological (multiculturalism and color-blindness) and self-regulatory (perspective-taking and stereotype-suppression) approaches to managing diversity. A first set of experiments found that exposure to multiculturalism facilitated perceptual and conceptual forms of perspective-taking. Specifically, a multicultural ideology prime strengthened motivations to engage in perspective-taking (Experiment 1) and led participants to adopt spontaneously an outgroup target's visual perspective (Experiment 2) and to recognize that an outgroup target did not possess their privileged knowledge (Experiment 3), as compared with a color-blind ideology prime or baseline condition. A second set of experiments documented the reciprocal relationship: Actively considering an outgroup member's perspective strengthened both deliberate (Experiment 4) and automatic (Experiment 5) positivity toward multiculturalism relative to color-blindness. These findings suggest that ideological and self-regulatory approaches to diversity management are intimately connected and can reinforce each other. 相似文献

The purpose of this research is to (a) identify which of recent history's influential figures did and which did not personify moral excellence, and (b) to examine the motives that drove these individuals along such divergent paths. In Study 1, 102 social scientists evaluated the moral qualities of influential figures from Time Magazine's lists. In Study 2, we selected the 15 top ranking of these figures to comprise a moral exemplar group and the bottom 15 to comprise a comparison group of similarly influential people. We measured the motivational aspects of their personality (agency and communion) by content-analyzing extant speeches and interviews. Moral exemplars exhibited the hierarchical integration of agency and communion by treating agentic motives as a means to an end of communal motives. Comparison subjects, by contrast, personified unmitigated agency by treating motives of agency as both a means to an end and an end unto itself. These results imply that both the strength and structure of a person's motives account for moral behavior. 相似文献

Members of Positive Behavior Interventions and Supports (PBIS) teams from 34 elementary schools participated in a Team-Initiated Problem Solving (TIPS) Workshop and follow-up technical assistance. Within the context of a randomized wait-list controlled trial, team members who were the first recipients of the TIPS intervention demonstrated greater implementation integrity in using the problem-solving processes during their team meetings than did members of PBIS Teams in the Wait-List Control group. The success of TIPS at improving implementation integrity of the problem-solving processes is encouraging and suggests the value of conducting additional research focused on determining whether there is a functional relation between use of these problem-solving processes and actual resolution of targeted student academic and social problems. 相似文献
