Effects of area size,heterogeneity, isolation,and disturbances on urban park avifauna in a highly populated tropical city

We assessed bird diversity and nesting activity in 54 urban parks in the core of a highly populated East-Asian tropical city to investigate the effects of area, isolation, habitat heterogeneity, and human disturbances on avifauna. Tree density and heterogeneity were lower while isolation was greater in small than in large or medium-sized parks. Yet, park features were often interrelated, with isolation variables negatively correlated to each other, heterogeneity positively correlated to area, and habitat variables mostly positively correlated with one another but variously to disturbances; whereas pedestrian densities wee positively correlated with green area proportions (ISO3) but negatively with the distances to large green areas (ISO2). Park size played a primary role by positively affecting species richness and numbers of nesting species, thus contributing to higher total and nesting species heterogeneity, and determining the occurrence of a greatest number of species. Pedestrian density, canopy cover, and ground heterogeneity played secondary roles, whereas isolation appeared less influential at the community level. Omnivores, granivores, and aerial insectivores appeared more abundant but were dominated by several common species. Nesting was restricted to even fewer species. While species varied in the occupancy responses to these factors, tree heterogeneity positively affected the nesting of Zosterops japonicus and cavity-nesting birds, and predator density negatively affected those of Lonchura punctulata and Streptopelia doves. Improved urban land use planning and park management incorporating these effects should be implemented to enhance breeding and avoid compositional homogenization for long-term sustainability of urban avian diversity.     

Ethnic Identity and Offending Trajectories Among Mexican American Juvenile Offenders: Gang Membership and Psychosocial Maturity

We examined the association of joint trajectories of ethnic identity and criminal offending to psychosocial maturity, gang membership, and Mexican American affiliation among 300 Mexican American male juvenile offenders from ages 14 to 22. There were two low‐offending groups: one was the highest in ethnic identity and changing slightly with age and the other was the lowest in ethnic identity and stable with age. A third group displayed moderately declining offending and moderately stable ethnic identity. A fourth group displayed high‐offending individuals with moderate, but increasing, levels of ethnic identity, who were initially lower in psychosocial maturity and more likely to be gang members. The findings highlight the need to contextualize theories of ethnic identity development.     

Lesbians in empirical psychological research: a new perspective for the twenty-first century?

Lesbians have been consistently ignored in empirical psychological research. The current research extends Lee and Crawford's ( 2007 ) comprehensive review, which used both quantitative and qualitative approaches to analyze the amount and kind of research on lesbians. Quantitative measures from 1975-2009 showed that the increase found in Lee and Crawford in 2001 has leveled off and the neglect of lesbians remains pronounced. Using cluster analysis of data derived from content analysis of abstracts published from 2003-2009, we identified six topic groups: Others' Attitudes, Sexual Orientation, Intimate Relationships, Coping and Coming Out, Lesbians' Problems, and Life in Heterosexual Society. In particular, transformative research was scarce and scattered across the identified clusters. Results are discussed in terms of what they reveal about the social construction of lesbianism in psychological research.     

Effects of pushing height on trunk posture and trunk muscle activity when a cart suddenly starts or stops moving

Unexpected sudden (un)loading of the trunk may induce inadequate responses of trunk muscles and uncontrolled trunk motion. These unexpected perturbations may occur in pushing tasks, when the cart suddenly starts moving (unloading) or is blocked by an obstacle (loading). In pushing, handle height affects the user's working posture, which may influence trunk muscle activity and trunk movement in response to the perturbation. Eleven healthy male subjects pushed a 200 kg cart with handles at shoulder and hip height in a start condition (sudden release of brakes) and a stop condition (bumping into an obstacle). Before the perturbation, the baseline of the trunk inclination, internal moment and trunk extensor muscle activity were significantly higher when pushing at hip height than at shoulder height. After the perturbation, the changes in trunk inclination and internal moment were significantly larger when pushing at shoulder height than at hip height in both conditions. The opposite directions of changes in trunk inclination and internal moment suggest that the unexpected perturbations caused uncontrolled trunk motion. Pushing at shoulder height may impose a high risk of low-back injury due to the low trunk stiffness and large involuntary trunk motion occurring after carts suddenly move or stop.     

The One-Child Policy and Gender Equality in Education in China: Evidence from Household Data

This paper uses individual-level data from the China Health and Nutrition Survey and examines the impact of the one-child policy on gender equality in education in China. The results showed children in one-child households enjoyed significantly improved opportunities for education compared to children inside multiple-child households. The improvement for girls was larger than that of boys. In addition, we found no difference in years of schooling between only-child boys and only-child girls, whereas the gap between boys and girls inside multiple-child households remained significant. In particular, years of schooling for girls having male sibling(s) were 0.62 years lower than that of girls having female sibling(s). These findings suggest the one-child policy inadvertently contributed to greater educational gender equality in China.     

Associations of the lower urinary tract symptoms with the lifestyle, prostate volume, and metabolic syndrome in the elderly males

This study aimed to evaluate the influence of the lifestyle, prostate volume (PV), and metabolic syndrome (MS) on lower urinary tract symptoms (LUTS) in the elderly males. A total of 764 men aged greater than 40 years were enrolled. Their severities of LUTS were assessed by the International Prostate Symptom Score questionnaire, while their MS was diagnosed according to the criteria developed by the National Cholesterol Education Program Adult Treatment Panel III. Lifestyle factors, PV, and components of MS were compared between no/mild and moderate/severe LUTS groups. In univariate analysis, age, cigarette smoking, alcohol consumption, physical activity, and PV significantly correlated with the severity of LUTS, but the presence or any components of MS did not. Results of multivariate analysis showed that aging, cigarette smoking, lack of regular exercise, and larger PV were independent predictors for moderate/severe LUTS. Notably, the risk factors for LUTS was influenced by the presence of MS. PV may play a role in determining the severity of LUTS for men without MS, while physical activity was the critical factor for men with MS. It was suggested that healthy lifestyle would be beneficial to lessen the severity of LUTS in the elderly males.     

A Comparison of Sanctions in African American and White TANF Leavers

In this study the authors explore racial disparities in the uses of sanctions and the different impact of sanctions on the economic well-being of African American and White TANF leavers. The study analyzed 907 African American and 1,336 White welfare leavers from the 1999 and 2002 data of the NSAF. Chi-square results show that sanctions are more significantly imposed to African Americans than Whites. On the other hand, regression results show that the impact of sanctions on the employment and family income of African Americans and Whites are comparable. Implications suggest that states need to have an appropriate sanction process, training programs for caseworkers, or other policy changes to reduce the racial disparities.     

Building organizational supports for knowledge sharing in county human service organizations: a cross-case analysis of works-in-progress

Building on the literature related to evidence-based practice, knowledge management, and learning organizations, this cross-case analysis presents twelve works-in-progress in ten local public human service organizations seeking to develop their own knowledge sharing systems. The data for this cross-case analysis can be found in the various contributions to this Special Issue. The findings feature the developmental aspects of building a learning organization that include knowledge sharing systems featuring transparency, self-assessment, and dissemination and utilization. Implications for practice focus on the structure and processes involved in building knowledge sharing teams inside public human service organizations.     

Latino Adolescent Reproductive and Sexual Health Behaviors and Outcomes: Research Informed Guidance for Agency-Based Practitioners

Latinos are the largest and fastest growing minority youth group in the United States. Currently, Latino adolescents experience higher rates of teen pregnancy compared to any other racial or ethnic group and have disproportionately high levels of sexually transmitted infections and HIV. Latino teens are also affected by a number of social problems such as school dropout, poverty, depression and limited access to healthcare, which contributes to disparities in reproductive health outcomes for this population. Relatively few intervention research studies and programs have been dedicated to reducing sexual risk among Latino youth, despite their particular vulnerabilities in experiencing negative reproductive health outcomes. We provide recommendations for identifying the unique reproductive health needs of Latino youth and specific applied strategies so that agency-based social workers and other providers can develop family-based interventions that improve adolescent Latino sexual and reproductive health.
