The significance of fathers for inner-city African-American teen mothers

Using the accounts of family life in young women's life stories, this qualitative study examined experiences with biological fathers for a sample of inner-city African-American teen mothers and a comparable sample of young women who were not parents. Distinguishing findings emerged about the pattern of young women's residential history with fathers, activity and interactions with fathers, and feelings about fathers. These qualitative findings were discussed in terms of their implications for services, policy, and research.     

Declining Physical Activity Levels as an Unintended Consequence of Abolishing Mandatory Campus Service Fees

Abstract

Objective: This study investigates the effect of the introduction of voluntary student unionism and subsequent increase in campus facility fees on engagement in physical activity on campus. Participants: Participants were 1,904 students from a large regional NSW (Australia) university across 3 time periods (926 in 2005, 504 in 2006, and 474 in 2007). Methods: Students completed a survey across the 3 time periods, responding to questions about physical activity levels, use of on-campus and off-campus facilities, and barriers to facility use. Results: Participation in physical activity at university facilities was low overall, and declined substantially between 2005 and 2007, with the proportion of students identifying cost as a barrier more than doubling over this time period. Conclusions: There is a need for policy makers to consider the unintended health impacts of such policy changes, particularly in relation to the impact on already insufficient levels of physical activity.     

The Multidimensionality of Presbycusis: Hearing Losses on the Content and Relational Dimensions of Speech

Presbycusis, the age associated decline in hearing and listening, has been traditionally conceptualized as the progressive inability to distinguish phonemes and hence to apprehend the content of spoken communication. Based on the distinction between the content and relational dimensions of communication, this study posed the possibility that presbycusis also involves a loss of listening ability along the relational dimension of communication. Using five measures of speech discrimination and listening, the study confirmed that aging is significantly associated with losses on the content and relational dimensions of listening. Furthermore, there are different rates of aging for these two dimensions. Whereas the loss on the content dimension is linearly related to age, the loss on the relational dimension is curvilinearly related to age with little decline in ability until a relatively drastic loss occurs in the early to mid-70s. These results indicate that the communicative impact of presbycusis is considerably greater for the old elderly than for the young elderly. Thus, this study constitutes initial evidence for a multidimensional conception of presbycusis.     

VALIDATION OF A DIARY MEASURE OF CHILDREN'S PHYSICAL ACTIVITIES

This study compares levels of physical activity of 9–14-year-old children from a self-reported time diary with those measured using an accelerometer. Children (N = 92) wore an accelerometer for one weekend day and completed a 24-hour time diary for that day. The time children spent in moderate to vigorous physical activity from time diaries was moderately highly correlated with the measured results. Self-reported and objective measures of intensity were correlated, but the correlation varied substantially by activity and characteristics of the family. This study provides empirical evidence to support the validity of time-diary estimates when accelerometer data are not available.     

Discrete Trial Instruction vs. Mand Training for Teaching Children With Autism to Make Requests

The present study compared the effects of discrete trial instruction (DTI) and mand training on the acquisition of independent requests in 6 children with autism. Two multiple-probe designs across participants were conducted with 3 participants receiving mand training followed by DTI and the other 3 receiving DTI followed by mand training. Eye contact and challenging behaviors were also assessed across conditions. Results indicate that 5 of 6 participants made more independent requests and acquired requesting faster in the mand training condition, had slightly better eye contact in the DTI condition, and fewer challenging behaviors in the mand training condition. Overall, the results indicate that mand training is a more efficient method for teaching children with autism to make requests.     

The politics of water scarcity in the western states

Water is a scarce and highly prized commodity in the arid Western states. Not surprisingly, water policy creation is very much a challenge for a number of reasons. Citizens hold multiple water values such as economic development and the protection of wildlife which are often contradictory. State prior appropriation laws are not easily reconciled with federal reserve rights and the public trust doctrine. There are multiple governmental and nongovernmental actors who work to influence and implement policy in a decentralized political system. If actors lose a policy battle in one decisionmaking arena (such as a legislature), they often try to influence policy at another venue (a court, Congress or an agency). Policymaking involves water issues that are dynamic over time. Furthermore, there are several types of water policy (distributive, allocative, redistributive and cooperative) that vary according to who pays costs and receives benefits, the level of conflict, the openness of decisionmaking to interested parties, and the level of government which dominates. Long ago, Mark Twain was correct when he said “Whiskey’s for drinking, water’s for fighting about.”     

Mother Involvement as an Influence on Father Involvement with Early Adolescents

This study hypothesized that father involvement is influenced by mothers' level of involvement as well as by marital conflict, mothers' work hours, and fathers' status as biological or step father. The analysis also tested hypotheses about mother involvement as a potential mediator of the effects of marital conflict and maternal work hours on father involvement, and hypotheses about factors influencing mother involvement. Children aged 10-14 from the NLSY79 who resided with their biological or step father and with their mother reported on each parent's involvement with them. As hypothesized, father involvement was predicted by mother involvement, and the reciprocal influence was not significant. Father involvement was associated with low marital conflict and being a biological father. Mothers' involvement partially mediated the effects of marital conflict on father involvement. If the mediating role of maternal involvement is not taken into account, the effect of marital conflict on father involvement is overestimated.     

Make assurance double sure: combination of two disclosure limitation methods and estimation of general regression models

In order to guarantee confidentiality and privacy of firm-level data, statistical offices apply various disclosure limitation techniques. However, each anonymization technique has its protection limits such that the probability of disclosing the individual information for some observations is not minimized. To overcome this problem, we propose combining two separate disclosure limitation techniques, blanking and multiplication of independent noise, in order to protect the original dataset. The proposed approach yields a decrease in the probability of reidentifying/disclosing individual information and can be applied to linear and nonlinear regression models. We show how to combine the blanking method with the multiplicative measurement error method and how to estimate the model by combining the multiplicative Simulation-Extrapolation (M-SIMEX) approach from Nolte (, 2007) on the one side with the Inverse Probability Weighting (IPW) approach going back to Horwitz and Thompson (J. Am. Stat. Assoc. 47:663–685, 1952) and on the other side with matching methods, as an alternative to IPW, like the semiparametric M-Estimator proposed by Flossmann (, 2007). Based on Monte Carlo simulations, we show that multiplicative measurement error combined with blanking as a masking procedure does not necessarily lead to a severe reduction in the estimation quality, provided that its effects on the data generating process are known.     

Theory of Mind in Preadolescence: Relations Between Social Understanding and Social Competence

Theory of mind (ToM) underlies the ability to attribute mental states to people as a way of understanding their social behaviour. Although ToM development is an active area of research, most empirical investigations focus on infants and young children. Accordingly, the purpose of this study is to assess ToM in preadolescents and to determine whether individual differences in this mentalizing ability relate to social competence and relate differently for girls and for boys. It was hypothesized that preadolescents' ability to understand thoughts and emotions in others would be associated with their social competence. 128 preadolescents (64 girls; 64 boys; mean age 11-9) completed peer social competence ratings, a vocabulary task, and participated in a social understanding (ToM) interview. Teacher ratings of the participants' social competence were also collected. Based on composite ToM scores, results indicated positive associations between ToM and (a) peer ratings of social-interaction skills, (b) general vocabulary ability. Separate gender analyses revealed significant effects. Results are discussed in relation to (1) individual differences in social understanding and social competence and (2) effects of socio-cultural context.
