Better Parents,More Stable Partners: Union Transitions Among Cohabiting Parents

Data from the Fragile Families and Child Wellbeing Study (N = 1,702 couples) are employed to examine the association between mother‐ and father‐reported parenting characteristics (father involvement and coparenting) and transitions out of cohabitation through marriage or separation in the 5 years after a child is born. Father involvement and coparenting may be signs of commitment and investment among couples without the legal bonds of marriage. Both the level and change in father involvement and coparenting are associated with a decreased likelihood of separation, although neither is associated with greater odds of marriage. These results suggest that higher levels of father involvement and a positive coparenting relationship may keep couples together, which allows children to spend their early years with both biological parents in the household.     

Multidisciplinary Child Protection Decision Making About Physical Abuse: Determining Substantiation Thresholds and Biases

The current study examined the threshold at which multidisciplinary child protection team (CPT) professionals substantiate physical abuse allegations and the extent that they utilize potentially biased constructs in their decision making when presented with the same case evidence. State legal definitions of child maltreatment are broad. Therefore, the burden of interpretation is largely on CPT professionals who must determine at what threshold physical acts by parents surpass corporal discipline and constitute child physical abuse. Biased or subjective decisions may be made if certain case-specific characteristics or CPT professionals' personal characteristics are used in making physical abuse determinations. Case vignettes with visual depictions of inflicted injuries were sent to CPT professionals in Florida and their substantiation decisions, personal beliefs about corporal discipline, and coercive discipline were collected. Results of the study demonstrated relatively high agreement among professionals across vignettes about what constitutes physical abuse. Further, CPT professionals strongly considered their perceptions of the severity of inflicted injuries in substantiation decisions. Although case specific characteristics did not bias decisions in a systematic way, some CPT professional characteristics influenced the substantiation of physical abuse. Practice implications and future directions of research are discussed.     

Science and Decisions: Advancing Risk Assessment

At the request of the U.S. Environmental Protection Agency (EPA), the National Research Council (NRC) recently completed a major report, Science and Decisions: Advancing Risk Assessment, that is intended to strengthen the scientific basis, credibility, and effectiveness of risk assessment practices and subsequent risk management decisions. The report describes the challenges faced by risk assessment and the need to consider improvements in both the technical analyses of risk assessments (i.e., the development and use of scientific information to improve risk characterization) and the utility of risk assessments (i.e., making assessments more relevant and useful for risk management decisions). The report tackles a number of topics relating to improvements in the process, including the design and framing of risk assessments, uncertainty and variability characterization, selection and use of defaults, unification of cancer and noncancer dose‐response assessment, cumulative risk assessment, and the need to increase EPA's capacity to address these improvements. This article describes and summarizes the NRC report, with an eye toward its implications for risk assessment practices at EPA.     

The Effect of Parental Divorce on Discomfort and Cardiac Activity in Response to Public Displays of Affection in College Females

Two studies examined the effect of parental divorce on feelings of discomfort and cardiac activity in response to public displays of affection (PDAs). In the first study, females from divorced homes reported marginally significant higher discomfort in response to PDAs than females from intact homes. In the second study, 32 female participants (16 from divorced homes and 16 from intact homes) viewed a PDA video and a control video and subsequently were asked to complete the same measure of discomfort as in Study 1. Interbeat intervals (IBIs) were recorded, and mean IBI and respiratory sinus arrhythmia (RSA) were derived. IBI and RSA increased in both groups in response to the videos over baseline. No differences were found between the divorce and intact groups for responses to the PDA video. However, the divorce group had higher heart rates and lower RSA overall, which suggests a potential mechanism for the association between divorce and negative physical health outcomes in women. Future studies should examine mediators of the relationship between divorce and reactions to PDA, such as marital conflict and parenting quality.     

自上而下，打破部门藩篱

顾客满意度不断降低,重要客户扬言要退出,一度认为可轻易达到的收入预期迅速下滑流失。然而,你绝非轻言失败之辈,于是在CEO的支持下,你拟定一份可令业绩再次回升的远大计划——这需要企业的全体人员同心协力,劲往一处使。问题在于,公司员工似乎很难记得:他们必须齐心协力。IT人员优先钟情于IT,而把公司利益置于其次;销售及设计部门同样如此。部门主管似乎花费更多时间用来争夺资源与认可,而对未来的挑战不甚热心。看起来,很少有经理人或员工能够超越部门局限,行动顾全公司的大局利益。换句话说,你的公司处于严重的藩篱状态。所谓“藩篱”…     

The sexual division of dieting: women's voices

This article reports the findings of focus group research on Australian women who have engaged in dieting practices to lose weight. There have been few qualitative sociological studies on dieting, despite it being a common practice among western women. From the empirical data in this study three distinct themes emerged: women participate in the perpetuation and reinforcement of the thin ideal; women clearly trade-off health in the pursuit of dieting to lose weight; and the dominant discourse of the thin ideal is not only mediated in various ways, but is also contested by a reverse discourse of size acceptance. A sociology of food and the body enables the discourses in the area of dieting women to be deconstructed, offering an insight into the gendered context of food, which has implications for the sociology of health and illness.     

The Emergence of the Listener to Speaker Component of Naming in Children as a Function of Multiple Exemplar Instruction

We tested the effect of multiple exemplar instruction on the transfer of stimulus function for unfamiliar pictures across listener responses (i.e., matching and pointing) and speaker responses (i.e., pure tacts and impure tacts). Three preschool students, who were 3- and 4-year-old males and did not have the listener to speaker component of the naming repertoire, participated in the experiment. The dependent variable was numbers of correct responses to probe trials of both untaught listener responses (“point to__”) and speaker responses (tact and impure tacts) following mastery of matching responses for two sets of five unfamiliar pictures (Set 1 and Set 3). After each participant mastered matching (e.g., “match Labrador”) for Set 1 pictures they were probed on the three untaught responses to Set 1 words. That is, they were asked to point to Labrador, tact the picture of Labrador, and respond to the picture of a Labrador and the question “What is this?” Next, the participants were taught mastery of all four types of responses using MEI for a second set of five pictures (Set 2) and probed again on the 3 untaught Set 1 responses. Finally, matching responses were taught to mastery for a novel set of pictures (Set 3) and then probed on the three untaught responses. The results showed that untaught speaker responses emerged at 60% to 85% for two participants, and 40%–70% for one participant. We discuss the role of instructional history in the development of the listener to speaker component of naming.     

Modifying a central composite design to model the process mean and variance when there are hard-to-change factors

Summary.  An important question within industrial statistics is how to find operating conditions that achieve some goal for the mean of a characteristic of interest while simultaneously minimizing the characteristic's process variance. Often, people refer to this kind of situation as the robust parameter design problem. The robust parameter design literature is rich with ways to create separate models for the mean and variance from this type of experiment. Many times time and/or cost constraints force certain factors of interest to be much more difficult to change than others. An appropriate approach to such an experiment restricts the randomization, which leads to a split-plot structure. The paper modifies the central composite design to allow the estimation of separate models for the characteristic's mean and variances under a split-plot structure. The paper goes on to discuss an appropriate analysis of the experimental results. It illustrates the methodology with an industrial experiment involving a chemical vapour deposition process for the manufacture of silicon wafers. The methodology was used to achieve a silicon layer thickness value of 485 Å while minimizing the process variation.     

Understanding Racial and Ethnic Disparities in Arrest: The Role of Individual,Home, School,and Community Characteristics

Contact with the justice system can lead to a range of poor health and social outcomes. While persons of color are disproportionately represented in both the juvenile and criminal justice systems, reasons for these patters remain unclear. This study sought to examine the extent and sources of differences in arrests during adolescence and young adulthood among blacks, whites, and Hispanics in the USA. Multilevel cross-sectional logistic regression analyses were conducted using data from waves I and IV of the National Longitudinal Study of Adolescent to Adult Health (n = 12,752 respondents). Results showed significantly higher likelihood of having ever been arrested among blacks, when compared to whites, even after controlling for a range of delinquent behaviors (odds ratio = 1.58, 95 % confidence interval = 1.27, 1.95). These black–white disparities were no longer present after accounting for racial composition of the neighborhood, supporting the growing body of research demonstrating the importance of contextual variables in driving disproportionate minority contact with the justice system.
