Family environments and the relationship context of first adolescent sex: Correlates of first sex in a casual versus steady relationship

Limited research has examined how family environments are associated with the relationship context of first sex, an important indicator of reproductive health risk. We use data from the 1997 National Longitudinal Survey of Youth to assess the association between the family environment - parent-parent relationships, parent-adolescent relationships, and family structure - and relationship context of first heterosexual sexual intercourse, distinguishing between the transition to first sex in serious and casual relationships. Twenty-five percent of females and 43% of males who had sex by age 18 did so in a casual relationship. All dimensions of the family environment were linked to the relationship context of first sex. Notably, higher parental monitoring was associated with a reduced risk of transitioning to first sex in a casual relationship versus no sex, and greater family routines were associated with a reduced risk of transitioning to sex in a steady relationship versus having no sex, for males and females. A strong maternal-adolescent relationship was associated with a reduced risk of first sex in a casual relationship but only for males. Additionally, in two-parent families, a strong father-adolescent relationship was associated with reduced risk of transitioning to casual sex, but only for females. Pregnancy and STI prevention programs should work with parents to foster positive parent-adolescent relationships, to become aware of their adolescents’ activities and to recognize that parents are important models for adolescent relationship behaviors.     

How Mood and Task Complexity Affect Children's Recognition of Others' Emotions

Previous studies examined how mood affects children's accuracy in matching emotional expressions and labels (label‐based tasks). This study was the first to assess how induced mood (positive, neutral, or negative) influenced five‐ to eight‐year‐olds' accuracy and reaction time using both context‐based tasks, which required inferring a character's emotion from a vignette, and label‐based tasks. Both tasks required choosing one of four facial expressions to respond. Children responded more accurately to label‐based questions relative to context‐based questions at the age of five to seven, but showed no differences at the age of eight, and when the emotional expression being identified was happiness, sadness, or surprise, but not disgust. For the context‐based questions, children were more accurate at inferring sad and disgusted emotions compared with happy and surprised emotions. Induced positive mood facilitated five‐year‐olds' processing (decreased reaction time) in both tasks compared with induced negative and neutral moods. Results demonstrate how task type and children's mood influence children's emotion processing at different ages.     

Modellgestützte Flexibilitätsanalyse von Strategien zur Ersatzteilversorgung in der Nachserienphase

An important task in after sales service is the provision of spare parts for durables. Due to its nature and dependence on earlier sales, the demand for spare parts is inherently dynamic and uncertain requiring for high procurement flexibility. During the product life cycle, inventory management of spare parts is performed efficiently under use of flexibility provided by existing production facilities. This situation completely changes once the OEM ceases production of the parent product. A prime option of procuring spare parts for the End-of-production period is to place a final order for parts when regular production ends. Besides low unit production costs, this option does not contain any flexibility, yielding a high risk of obsolescence of stored parts, and at the same time a high risk of not being able to satisfy all demand during the service period. In order to increase flexibility further options like extra production at higher unit cost or remanufacturing of components taken from used products could be used. After introducing the problem and a basic quantitative model, we evaluate flexibility properties of strategies using different combinations of the above options. In doing so we distinguish between quantity, time, and stock related flexibility. In a comprehensive numerical study it is investigated to which extent flexibility properties of the different strategies can contribute to their economic profitability.     

Evaluation of two school‐based HIV prevention interventions in the border city of Tijuana,Mexico

This research project examined the individual and combined effectiveness of an HIV prevention workshop and a free condom distribution program in four high schools in Tijuana, Mexico. Adolescents (N = 320) completed baseline measures on sexual practices and theoretical correlates and participated in a two‐part study. In Study I, students were randomly assigned to an HIV prevention workshop or a control condition, with a 3‐month follow‐up assessment. Results indicate three significant workshop benefits regarding HIV transmission by altering sexual initiation, access to condoms, and traditional beliefs regarding condoms. In Study 2, we set up a condom distribution program at two of the participating schools, and students completed a 6‐month follow‐up assessment. Results indicate that exposure to the workshop followed by access to the condom distribution program yielded two beneficial results for reducing HIV transmission: moderating sexual initiation and increasing condom acquisition. Access to the condom distribution program alone had no effects on behavioral and psy‐chosocial correlates of HFV transmission. We discuss implications of these results.     

Texting among United States young adults: An exploratory study on texting and its use within families

The current study examines general text messaging tendencies, patterns of and reasons for texting family members, and the impact of texting on familial relationships among a young U.S. adult sample. Participants were recruited through Facebook; they then completed an online questionnaire. Data from 127 young adults (men: 38; women: 87; unidentified: 2) are analyzed and compared by gender. Findings suggest that young adults text at high rates per month. Participants generally report a prompt response to texts and their ability to honestly express feelings within these messages. Results also suggest participants text family members for a variety of reasons, such as to convey information, plan activities, and engage in general conversation. Distinct gender differences, however, are evident regarding who men and women text as well as texting's effects on familial relationships. Overall, these findings expand researchers’ understanding of texting in general and its impact within the family.     

Innocence Lost: Accomplishing Victimization in Intimate Stalking Cases

This article explores identity work and emotion management in felony domestic violence stalking cases, using data collected in a domestic violence unit in a large metropolitan district attorney's office. Victim narratives in crime reports, intensive interviews of stalking victims, and participant observation in a stalking survivors' support group show how women become “victims” in the criminal justice system. Sometimes women's continued interaction with both stalkers and law enforcement actors affects their ability to create and sustain credible victim identities. Almost any action a victim takes or presentation she makes has the potential for inducing negative identity attributions. Thus identity dilemmas seemingly inhere in the stalking situation.     

Using Discrete-Time Event History Fertility Models to Simulate Total Fertility Rates and Other Fertility Measures

Event history models, also known as hazard models, are commonly used in analyses of fertility. One drawback of event history models is that the conditional probabilities (hazards) estimated by event history models do not readily translate into summary measures, particularly for models of repeatable events, like childbirth. In this paper, we describe how to translate the results of discrete-time event history models of all births into well-known summary fertility measures: simulated age- and parity-specific fertility rates, parity progression ratios, and the total fertility rate. The method incorporates all birth intervals, but permits the hazard functions to vary across parities. It can also simulate values for groups defined by both fixed and time-varying covariates, such as marital or employment life histories. We demonstrate the method using an example from the National Survey of Family Growth and provide an accompanying data file and Stata program.     

Hierarchical linear modeling as an example for measuring change over time in a leadership development evaluation context

One of the difficulties in evaluating leadership development is measuring whether and how people change over the time period of the leadership development initiative. Even when change over time is an inherent part of the design and evaluation of leadership development, events may occur outside of the control of evaluators that limit the effectiveness of adequately and accurately assessing change over time. With data from a leadership development initiative designed to account for change over time, this article suggests hierarchical linear modeling (HLM) as a multilevel methodological technique to assess change over time in a leadership development context. This article will use real change over time data from a leadership development initiative and discuss the logic and rationale of HLM. We use HLM as an example of a multilevel methodological tool to investigate typical change over time questions in leadership development evaluation.
