Passive versus active parental permission in school-based survey research: does the type of permission affect prevalence estimates of risk behaviors?

This study investigates whether the type of parental permission affects prevalence estimates for risk behaviors from the national 2001 Youth Risk Behavior Survey. Participants were 13,195 students from 143 schools, of which 65% used passive permission and 35% active permission. Student participation rates were 86.7% in passive permission schools and 77.3% in active permission schools. For 24 of 26 behaviors tested, no significant differences were seen in the prevalence of risk behavior by type of parental permission. As long as high response rates are obtained, type of parental permission does not affect prevalence estimates for risk behaviors that are based on self-report.     

How does the size and shape of local populations in China compare to general anthropometric surveys currently used for product design?

Anthropometry has long been used for a range of ergonomic applications & product design. Although products are often designed for specific cohorts, anthropometric data are typically sourced from large scale surveys representative of the general population. Additionally, few data are available for emerging markets like China and India. This study measured 80 Chinese males that were representative of a specific cohort targeted for the design of a new product. Thirteen anthropometric measurements were recorded and compared to two large databases that represented a general population, a Chinese database and a Western database. Substantial differences were identified between the Chinese males measured in this study and both databases. The subjects were substantially taller, heavier and broader than subjects in the older Chinese database. However, they were still substantially smaller, lighter and thinner than Western males. Data from current Western anthropometric surveys are unlikely to accurately represent the target population for product designers and manufacturers in emerging markets like China.     

How does the stigma of problem gambling influence help-seeking,treatment and recovery? a view from the counselling sector

Problem gambling attracts considerable public stigma and can cause significant self-stigma. However, little research has investigated the role of stigma during treatment-assisted recovery from problem gambling. This study aimed to examine gambling counsellors’ perspectives on whether and how the stigma associated with problem gambling influences problem acknowledgement, help-seeking, treatment and recovery. In-depth interviews with nine gambling counsellors from Victoria, Australia, were analysed to extract shared meanings of experiences using interpretative phenomenological analysis. Counsellors indicated that the burden of problem gambling is typically increased by the addition of stigma and its impacts. This stigma is created and maintained by a lack of public understanding about problem gambling and its causes, and internalization of self-stigmatizing beliefs, leading to delayed help-seeking, anxiety about attending treatment, concerns about counsellor attitudes, and fear of relapse. Counsellors maintained that, before effective gambling treatment could occur, they needed to help clients overcome their self-stigmatizing beliefs to establish confidence and trust in the counsellor, restore self-esteem, enhance stigma coping skills and foster a belief that recovery is possible. Harnessing support from significant others and preparing clients for relapse were also important inclusions to lower stigma. Addressing stigma early in treatment can help to improve treatment adherence and recovery.     

How does paid work affect who does the childcare? An analysis of the time use of Australian couples

This paper analyzes the effect of paid work by coupled parents of young children on the joint decisions to spend time engaged in childcare. We explore this using Australian Time-Use Survey data from 2006. We examine the effect of paid work in terms of the effect that total work time on a given day has on the amount of time spent on childcare; the allocation of time on activities across work and non-work days; and the effect of non-traditional work hours. The results show that mothers perform a large share of childcare, irrespective of their earning power or their partner’s availability to take on some of these tasks. The use of formal and informal childcare by others allows the mother to balance the competing demands of work and her own childcare; an effect that does not hold for fathers. These effects on childcare are also almost solely concentrated in the routine component of childcare (e.g. preparing meals, changing nappies), with each parent ‘protecting’ interactive childcare from the effect of both paid work and the relative availability of their partner to take on some of this childcare.     

How does it depend?: A systematic review of the contingency theory of accommodation in communication scholarship

This study conducted a systematic review of the ways in which Contingency Theory of Accommodation has been developed over the past two decades. Using an interdisciplinary approach, we analyzed the trends (e.g., journal, publication volume, research contexts) as well as the theoretical and methodological approaches utilized in Contingency Theory studies. Findings from a content analysis (N = 223) conclude that the theory has established itself as a dominant framework for crisis communication scholarship and shows clear patterns of epistemological advancement. However, the most pressing challenge for future scholarship is the need to revitalize the theory by incorporating more diverse conceptual approaches and further methodological sophistication in measurement for the 86 contingency factors.     

Quantifying the magnitude and potential influence of missing data in campus sexual assault surveys: A systematic review of surveys, 2010–2016

Objective: To understand how missing data may influence conclusions drawn from campus sexual assault surveys. Methods: We systematically reviewed 40 surveys from 2010–2016. We constructed a pseudo-population of the total population targeted across schools, creating records proportional to the respective response rate and reported sexual assault prevalence. We simulated the effects of 9 scenarios where the sexual assault prevalence among nonresponders differed from that of responders. Results: The surveys represented a total female undergraduate population of 317,387 with only 77,966 (24.6%) survey responses. Among responders, 20.4% reported experiences of sexual assault. However, prevalence of sexual assault could theoretically range from 5.0 to 80.4% under extreme assumptions about prevalence in nonresponders. Smaller, but still significant differences were observed with less extreme assumptions. Conclusions: Missing data are widespread in campus sexual assault surveys. Conclusions drawn from these incomplete data are highly sensitive to assumptions about the sexual assault prevalence among nonresponders.     

How does the Huntington''s disease mutation damage cells?

Huntington's Disease (HD) is an autosomal dominant neurodegenerative condition with devastating consequences. HD is caused by the expansion of a CAG trinucleotide repeat stretch in the coding sequence of the HD gene that gives rise to a long polyglutamine tract in the huntingtin protein. How this mutated protein gives rise to the disease state is controversial. In this Perspective, I discuss the results of a new study on the effects of the mutated huntingtin protein in light of previous findings and suggest that the HD mutation damages cells by perturbing multiple parallel pathways by gain-of-function and possibly also dominant negative mechanisms.     

The influence of exercise on the functioning of the pituitary–gonadal axis in physically active older and younger men

Age is a meaningful factor modulating the functioning of the human endocrine system. In our research, the factor stimulating the pituitary–gonadal axis was a 400 m race. In this type of effort, glycolytic and lactic acid transformations are dominant and a fundamental increase in lactic acid concentration is noted. The aim of the research was to compare the response of the pituitary–gonadal axis in physically active men of various ages after a 400 m race. Nine men aged 21.7 ± 0.7 years and nine men aged 60.0 ± 3.4 years took part in the study. Blood samples were taken from the elbow vein before the race at 08.00 and immediately after the effort. The levels of luteinizing hormone (LH), follicle stimulating hormone (FSH), total testosterone and free testosterone were determined in blood sera. The concentration of lactic acid was measured in full blood at 5 min after the race. Before the effort, statistically significant differences in the concentration of FSH and free testosterone between the two age groups were observed (higher FSH in older men but lower free testosterone). No differences in the level of LH, total testosterone and lactic acid were observed. Immediately after the effort, no changes in the level of FSH were found in both groups; a statistically significant decrease in LH concentration was noted only in the group of younger men. In both groups, statistically significant increases in total testosterone, free testosterone and lactic acid concentrations were observed after the race. In the group of younger men, compared to the older, larger increases in free testosterone and lactic acid concentrations, as well as shorter race time, were revealed after the effort test. Analysis of the two groups after the race showed statistically significant differences in FSH, free testosterone and lactic acid concentrations. A positive correlation (r = 0.57) was demonstrated between the after-effort increase in the concentration of free testosterone and lactic acid, and negative correlation (r = –0.66) between the after-effort increase in the concentration of free testosterone and the time of the 400 m race. In older men, the concentration of free testosterone may play an important function in lowering strength capacities. It must be stressed that the 400 m race was a more significant stimulus for changes in hormone concentrations of the pituitary–gonadal axis in younger men (greater changes in the level of the investigated parameters) than in the older. The results obtained allow us to conclude that, in older men, as compared to the younger ones, the response of the pituitary–gonadal axis to an effort stimulus is to some extent different.     

Participant responses to retrospective surveys of child maltreatment: does mode of assessment matter?

This study examines the impact that different methods of assessing child maltreatment history may have on adult participants. A total of 334 female undergraduate students were randomly assigned to complete a retrospective measure of child sexual and physical abuse in one of three conditions: paper-and-pencil questionnaire, face-to-face interview, or computer-administered survey. Disclosure rates of abuse, psychological distress and mood change, preferences for assessment format, and perceptions of confidentiality were examined across the three assessment formats. Although disclosure did not vary by condition, participants with a history of abuse reported more distress and mood change than did nonvictims, particularly in the computer condition. Nevertheless, the computer condition was rated as the most preferred format and was viewed by participants as the most confidential means of assessing maltreatment history. Participants reporting abuse through interviews were more likely than those in other conditions to state a preference for another type of assessment format. The implications of these findings for abuse history research are discussed.     

Does religion influence the labor supply of married women in Germany?

Using behavioral theories, this article analyzes whether religion influences married women in Germany in their decision to supply labor. Gender roles and accompanying attitudes toward the division of labor among spouses might differ across religious groups depending on the groups’ strictness. Examining data from the GSOEP, the findings suggest that denominational affiliation itself only weakly influences women’s labor participation decisions. However, women who participate regularly in religious activities are less inclined towards paid employment. Furthermore, there is evidence that the presence of a spouse with a strong belief also affects a woman’s supply of labor negatively.     

How does a board of directors influence within‐ and cross‐sector nonprofit collaboration?

Board members play a significant, yet largely unexamined, role in nonprofit collaboration. Processes, such as finding prospective partners, creating common ground with a partner, and establishing appropriate collaborative governance implicate nonprofit board members. In contrast to the scholarship of the role of interlocking directorates as potential networks for nonprofit collaboration, this paper examines the role of board members' social and human capital on nonprofit collaboration with other nonprofits, businesses, and government agencies. Drawing on online survey data from 636 nonprofit organizations, this paper finds that board social capital—but not board human capital—is positively related to the presence and number of within‐sector and cross‐sector nonprofit collaboration. However, board human capital enhances nonprofit‐government collaboration, when board social capital is also high. The results provide a novel perspective in nonprofit collaboration and board management research.     

Exploring the new child protection system in Mainland China: How does it work?

Child protection has become an increasingly important issue in China. Notably however, few studies have explored the Chinese child protection system itself. The purpose of this study is to explore the basic elements of China's child protection system, which was initiated as a pilot program in May 2013, in order to find out how this child protection program works. A content analysis approach was used for this study. A total of 97 related public documents and 11 supplemented interviews were analyzed. We report on the five major categories of basic elements of China's child protection, accompanied by a detailed analysis. Findings show that: (1) The child protection pilot program aims to serve more vulnerable and disadvantaged children rather than abused and neglected children; (2) Although Minors' Protection Office was established to specialize in improving child protection mechanisms and services, a number of agencies bear the primary responsibilities of children protection in practice; (3) A reporting system for reporting suspected child abuse has been advocated in the practice of child protection for the first time; (4) Domestic child protection organizations and institutions play important roles in providing alternative care services. The findings presented in this paper also indicate that although a basic framework for child protection has formed in pilot areas, there are significant barriers to developing and implementing such a system.     

Do required fields in online surveys in the social sciences impair reliability?

ABSTRACT

The present study is the first to examine empirically whether required fields in online surveys impair reliability and response pattern, as participants forced to respond to all items may provide arbitrary answers. Two hundred and thirteen participants completed a survey consisting of six questionnaires testing personal and social issues and perceptions. They were randomly assigned to one of two versions of the survey: optional-fields (N = 104) or required-fields (N = 109). Comparison of the Cronbach’s alpha of the two versions revealed identical reliability values for all questionnaires, save for somatization, where a minor difference was found. Confirmatory factor analysis showed no difference in the factor structure of the two versions, and no differences were found by Bayesian t-test and Levene’s test for equality of variances. The findings suggest that required fields do not impair reliability or change the response pattern, and therefore can be used in online surveys to prevent missing data.     

How does discharge status impact suicide risk in military veterans?

Little is known about over 125,000 veterans who received non-honorable military discharges since 2001, even though these veterans face substantial barriers to obtaining services and are likely to be at high risk for negative mental and behavioral health outcomes including suicide. Seven-hundred twenty-two veterans living the in the San Francisco Bay Area participated in the study. The sample comprised honorably discharged (n = 508) and non-honorably discharged veterans (n = 214). T-tests were used to compare means on predictors of suicide risk including Posttraumatic Stress Disorder (PTSD), depression, alcohol use, somatic symptoms, and physical disability. A series of regression models tested relationships between predictors, discharge status, and suicide risk. Non-honorably discharged veterans demonstrated higher mean scores than honorably discharged veterans on all predictors. In regression models, somatic symptoms (β = 0.22, p < 0.001), physical disability (β = 0.16, p < 0.05), and discharge status (β = 0.33, p < 0.001) were associated with suicide risk. The final model showed an interaction effect for discharge status on the relationship between somatic symptoms and suicide risk (β = 0.16, p < 0.05). Non-honorably discharged veterans showed higher rates of mental and physical health problems and suicide risk compared to honorably discharged veterans. The magnitude of the relationship between somatic symptoms and suicide risk was significantly greater in non-honorably discharged veterans.     

Social capital and disasters: How does social capital shape post-disaster conditions in the Philippines?

ABSTRACT

Social capital is a common feature among disaster-resilient communities. This research aims to define how social capital shapes the post-disaster conditions in the 2011 Typhoon Washi-affected communities of Cagayan de Oro and Iligan City in Region 10 Philippines. Qualitative analysis was used in analyzing the data gathered through purposive sampling and semi-structured interviews. Thirty typhoon survivors and 14 focal persons of the government and non-government agencies were chosen based on their active involvement in the community. The findings revealed that the solidarity among typhoon-affected communities contributed to the recovery of the survivors. The findings also highlighted that the solidarity in the typhoon-affected communities is part of the normative structure of the society where bonding and linking social capital are nurtured. Further, the community remains to believe that their respective local officials can be trusted and are capable of helping them in times of need despite the shortcomings during the 2011 Typhoon Washi. We argue that social capital in the community is not easily diminished over a crisis and therefore must be nurtured towards effective community-based disaster resilience mechanisms.     

Does the sense of the geographic proximity of a requester influence donation? Three evaluations in field studies

It has been reported that familiarity or incidental similarities with a stranger influenced an individual’s behavior. However, the effect of the sense of geographical proximity believing that someone comes from the same area that somebody has never been examined. Three field experiments examined this effect on donations to humanitarian organizations. In the first study, participants were asked by a confederate to donate food products to a humanitarian organization. In Study 2, participants were asked by confederates to donate money for children. In Study 3, donation boxes were displayed in bakeries with a message that invited customers to donate money for children. In all the studies, participants were led to believe that they would be helping people in need or people who live in their national or local geographic area. Results showed that donations were higher in the geographical proximity condition. This “neighborhood effect” was discussed.     

Active parental consent in school-based research: how much is enough and how do we get it?

Active parental consent policies have been blamed for low participation rates and selection bias (i.e., loss of "high-risk" youths) in school-based studies. In this article, the authors describe active consent procedures that produced an overall active consent rate of 79% in a sample of more than 4,500 middle school students attending 29 schools in seven cities across the United States. Consent rates, however, varied considerably both within and between schools. To better understand factors associated with active parental consent rates, the authors examined district-level, school-level, and teacher-specific effects on consent rates.
