Demography of a ground nesting bird in an urban system: are populations self-sustaining?

Urbanization poses threats to earth’s biota, and retention of remnant native habitat in protected areas within expanding urban boundaries may help alleviate threats to wildlife. However, it is unclear for nearly all nonsynanthropic (i.e., not benefiting from an association with humans) species whether vital rates in urban habitats can sustain populations or if populations persist only through immigration from outside the urban boundary. We conducted a three-year study of spotted towhees (Aves: Pipilo maculatus) breeding in four undeveloped parks in Portland, OR, USA, to measure park-specific seasonal reproductive output (F) and annual adult survival (S_A). We developed a stochastic model that combined F and S_A with an estimate of first-year survival to measure population growth rate (λ) in all parks assumed to be closed to immigration. F differed among parks but S_A did not. Relatively high F was possible because many pairs raised >1 brood/season. When combined with empirical estimates of survival through the 30-day period of post-fledging parental care (S_D = 0.645), only 2 of 4 parks were self-sustaining (i.e., λ > 1.0). However, S_D reflected substantial loss of fledglings to domestic cats (Felis catus). Assuming no loss to cats and either partial compensatory or additive mortality of fledglings substantially improved prospects of population persistence for declining (sink) populations. Moreover, allowing low levels of immigration to sinks reversed population declines in most parks even when vital rates were insufficient to maintain populations. Our results suggest that nonsynanthropic bird species can persist in urban landscapes, but also that offspring mortality in the post-fledging period may be a critical determinant of population viability.     

Developmental Outcomes of School Attachment Among Students of Mexican Origin

We used a longitudinal community study of 674 grade school children (Grades 5, 6, 7, and 8; 337 males, 337 females) of Mexican origin to examine outcomes of school attachment. Attachment to school is important in this population given the high level of school dropout rates of Mexican‐origin students. Results indicated that, on average, school attachment from fifth to sixth grade remains stable, but declines from sixth to eighth grade. Boys had lower levels of school attachment at fifth grade but followed similar patterns of change as girls did. Attachment to teachers, peer competence, school aspirations and expectations, and substance‐use cognitions emerged as longitudinal outcomes of level or changes in school attachment. Gender moderated associations of school attachment.     

Defining Women's Global Political Empowerment: Theories and Evidence

Although women's access to political power has increased tremendously, nowhere are women equal to men in their influence over and exercise of political authority. Scholarship on women's political empowerment is uneven and incomplete. This article interrogates ‘women's political empowerment’, considering its definition, measurement, and application. First, we establish that academics and practitioners have not articulated a clear definition of women's political empowerment. To fill this gap, we put forward a new definition that conceptualizes women's political empowerment as a transformative process. We then review existing social science literature on women's political empowerment. We argue that scholars must expand research to develop a broader vision of women's political empowerment and develop measures that capture this breadth.     

Longitudinal Consistency in Self-Reported Age of First Vaginal Intercourse among Young Adults

We examined consistency in self-reports of age at first vaginal sex among 9,399 male and female respondents who participated in Waves III and IV (separated by approximately seven years) of the National Longitudinal Study of Adolescent Health (Add Health). Respondents were coded as consistent if they reported an age at first vaginal intercourse at Wave IV that was within one year of the age they reported at Wave III. Sociodemographic, behavioral, and cognitive predictors of consistency were examined using bivariate and multivariate logistic regression. Overall, 85.43% of respondents were able to provide consistent reports. Among both males and females, consistency was associated with age, years since first vaginal intercourse, race/ethnicity, and lifetime number of other-sex partners in final multivariate models. Respondents who were older and had more recently had their first sexual experience were more likely to be consistent. For females only, those who reported a history of nonparental, physically forced sex were less likely to be consistent. Most young adults consistently report age at first vaginal intercourse, supporting the credibility of retrospective self-reports about salient sexual events such as timing of first vaginal intercourse.     

The Trauma Trifecta of Military Sexual Trauma: A Case Study Illustrating the Integration of Mind and Body in Clinical Work with Survivors of MST

Military sexual trauma (MST) has recently received much attention from the media in contemporary society. With the ever-increasing population of United States service members returning from the Iraq and Afghanistan wars, it is vital for any mental health practitioner to be aware of the epidemic that is sexual assault in the military, the unique trauma experiences of the MST survivor, and treatment implications incorporating multiple psychological theories. This article explores three factors, referred to as the trauma trifecta, in which the effects of MST are exacerbated: the loss of professional and personal identity, the regulatory functions of self harm behaviors, and the retraumatization that many service members endure as a result of the distinctive characteristics of the military culture and its service to veterans. A case study with clinical interventions will be utilized to demonstrate this concept of “the trauma trifecta” and the unique challenges in treating the PTSD symptoms that can result from MST in clinical therapy. Drawing from multiple theories in clinical treatment, this paper illustrates the strengths and limitations of cognitive-behavioral techniques, highlights the integration of feminist theory to illustrate the obstacles of power structures, and mind–body interventions, bridging the gap between talk therapy and body therapy. Through this unique integration of multiple therapies, the case study illustrates the veteran’s reengagement with her body and the reformulation of her identity post MST.     

All Shook Up: Sexuality of Mid- to Later Life Married Couples

The authors integrate theoretical work on the performance of gender with a life course perspective to frame an analysis of in-depth interviews with 17 long-term married couples. The findings indicated that couples' sexual experiences are characterized by change over time, yet that change is shaped by the intersection of gender and age. Midlife couples (ages 50 - 69) were distressed by changes in their sex lives likely because they impede couples from performing gendered sexuality. The source of this distress stems from age-related physical changes; however, it manifests in different ways for husbands and wives. In contrast, later life couples (ages 70 - 86) were more likely to emphasize the importance of emotional intimacy over sex as they age. Marital sex is a source of conflict for many midlife couples because of husbands' and wives' incongruent experiences, but later life husbands and wives tend to have more congruent experiences of marital sex.     

The relationship of intimate partner aggression to head injury, executive functioning, and intelligence

Measures of head injury, executive functioning, and intelligence were given to a community sample composed of 102 male perpetrators of intimate partner aggression (IPA) and 62 nonaggressive men. A history of head injury and lower mean score on a measure of verbal intelligence were associated with the frequency of male-perpetrated physical IPA as reported by male perpetrators and their female partners. Lower mean scores on a measure of verbal intelligence also predicted frequency of psychological IPA perpetration. Using the perpetrator subtypes outlined by Holtzworth-Munroe et al. (2000), analyses revealed that compared with other groups, the most severely aggressive subtypes (i.e., borderline-dysphoric and generally violent-antisocial) were the most likely to report a history of head injury and to have significantly lower mean scores on a neuropsychological test of verbal intelligence. The possible role of neuropsychological factors in IPA perpetration and implications for prevention and intervention programs are discussed.     

Obstacles for child participation in care and protection cases—why Norwegian social workers find it difficult

Although some attempts are being made to increase children's participation in Norwegian child protection cases, much needs to be done in order to comply with the participation principle in the United Nations Convention on the Rights of the Child. This paper reports on a study of factors that are likely to predict if social workers will attempt to give children an effective voice in decision making processes. 53 child protection case managers and 33 social work students participated in a questionnaire survey in which they were asked to agree or disagree with 20 statements about child participation. Statistical factor analysis was used in order to identify underlying factors in the dataset. The results suggest three main reasons for children not being allowed to participate: communication difficulties (communication factor); because child participation was not deemed necessary (participation advocacy factor); or that participation was considered inappropriate because it might be harmful (protectionism factor). This research suggests that, if we are to improve participation within the child protection system, formal regulations and guidelines need to be accompanied by a greater attention to development of social work skills in working with children through participatory processes.

Thermal comfort and personal protective equipment (PPE)

Personal Protective Equipment (PPE) is considered the last preferred solution to an Occupational Safety Health (OSH) system. Brazilian OSH legislation assumes and requires PPE usage to neutralize the possibility of pesticide contamination. This study examines the inadequacy of the PPE used in a tomato crop, particularly from the standpoint of thermal comfort. This study made observations regarding heart rate and body temperature in a controlled environment using a treadmill (with and without PPE) of 12 volunteers; and during the process of rural labor (at rest and in normal work routine) of 2 actual rural workers. Comparing the results of the treadmill test (with and without PPE) which tried to reproduce the same level of effort and environmental conditions of the actual rural work, this study demonstrated that PPE makes thermoregulation harder and tympanic temperature reaches higher values with the same level of effort. Moreover, body temperature increases quickly: with PPE it took 15 minutes to raise 1°C in body temperature, compared to 40 minutes without PPE. The results of this study indicated that the use inadequate PPE might pose thermoregulation risk to rural workers.
