Positive affect regulation in youth: Taking stock and moving forward

This article summarizes the four articles in the Social Development quartet focused on positive affect regulation in youth. Each article in the quartet shows that parents’ socialization of youth positive affect (e.g., encouraging, enhancing, savoring, or dampening responses) is associated with youth positive affect regulation and depressive symptoms. Further, three of the studies provide novel evidence for an indirect relationship whereby parental socialization predicts youth depressive symptoms through youth positive affect regulation. The studies include samples of youth across mid‐childhood and adolescence (7–18‐year‐olds) from three countries (the United States, Belgium, and India), and utilize several methods of assessing youth positive affect regulation or parental socialization (parent‐reported surveys, youth‐reported surveys, coded parent–child discussions). This integrative article also identifies several ways in which the study of youth positive affect regulation can be advanced. We address the conceptualization of positive affect regulation and the socialization of children's positive affect, constraints on the adaptiveness of upregulating positive emotions, methodological directions, potential moderated effects based on child characteristics such as sex or temperament, and the importance of studying outcomes beyond depression.     

Application of load-oriented manufacturing control in industry

This paper deals with multi-stage lotsizing models for imperfect production processes. The effect of imperfect quality on lotsizing decisions and effect ofinspection errorsare taken into consideration in the proposed models. Numerical examples are presented for illustration purposes. The developed models are very helpful for justifying quality assurance and quality improvement efforts.     

Movement-in-depth, cognitive impairment, and crash risk

In this study, 243 cognitively intact and cognitively impaired older participants' movement-in-depth (looming) abilities were assessed using a portable device that we had previously developed in our laboratory. Results indicated normative relationships between looming ability and age, looming ability and driving violation records, and age and driving violation records. Findings also confirmed the validity and reliability of the measurements taken with the device. In conclusion, this device may be useful for identifying drivers at risk for rear-end collisions, developing effective training interventions, and creating fair and valid driver licensing tests.     

Maternal socialization of children’s positive affect regulation: Associations with children’s savoring,dampening, and depressive symptoms

Maternal socialization of positive affect (PA) is linked to children's regulation of positive and negative emotions and the development of psychopathology. However, few studies have examined multiple types of emotion socialization as related to children's PA regulation and depressive symptoms. The current study examined how mothers’ socialization of children's PA regulation was related to children's PA regulation, and if children's PA regulation mediated the association between maternal socialization and children's depressive symptoms. Ninety‐six mother–child dyads (children aged 7–12) completed questionnaires and a five‐minute discussion about a positive event the child previously experienced; 76 dyads completed surveys again five months later. Partial correlations, controlling for child age and gender, indicated associations between maternal PA socialization and child PA regulation. Moderated mediation models suggested that maternal modeling of savoring predicted Time 2 child depressive symptoms via children's own savoring, which was moderated by Time 1 depressive symptoms. The moderated path indicated that only for children who reported higher depressive symptoms at Time 1, higher levels of savoring predicted lower depressive symptoms at Time 2. These results underscore the importance of examining multiple types of PA socialization and child PA regulation to predict children's depressive symptoms longitudinally.     

A literature review of major perceptual, cognitive, and/or physical test batteries for older drivers

Driving is one of the most complex tasks that humans perform on a regular basis, placing significant demands on human perceptual, cognitive, and motor capabilities, so age-related declines in these capabilities negatively affect driving performance. Although older adults create a risk on the road because of their high crash rates, it is important to note that not all older drivers have impaired driving performance or high crash risk. Thus researchers have developed test batteries to identify at-risk older drivers. The literature pertaining to the development and testing of at-risk driver assessment tools, including major assessment tools and evidence supporting their use is reviewed.     

Using practical ergonomic evaluations in the restaurant industry to enhance safety and comfort: a case study

Restaurant employees must deal with loud noise, busy environments, difficult customers, heavy, awkward, sharp, and hot objects, repetitive motions, and stress on various joints, all of which can lead to fatigue, sudden accidents, and longterm musculoskeletal injury. The goal of this case study was to assess the risk of injuries and accidents from conducting various tasks in the restaurant, specifically carrying/lifting, table management, and polishing silverware. The nine participants were servers at a local country club restaurant. Physical workload was measured by a scale of physical exertion. Cognitive workload was assessed, as well as cumulative trauma disorder risk. Overall results show that there is sufficient risk in some of the tasks to warrant concern. Specific results are discussed, as well as recommendations for improved safety.     

Rewiring global networks at local events: congresses in the stock photo trade

Digital technologies have enabled the geographical expansion of production and the distribution of creative goods and communication. Simultaneously, the number of trade fairs and congresses has increased. This rise of temporary encounters has led to theorizations of events as marketplaces, learning sites and field‐configuring practices. This article elaborates on the metaphor of rewiring to propose and empirically demonstrate a further role of industry events for global business. Drawing on the case of the global stock photo trade, we use a unique survey to map the global network of sales partnerships as well as interviews conducted at international lead congresses to demonstrate how these events are enacted as social relays. Our findings demonstrate how temporary face‐to‐face contact facilitates long distance relationships between organizations and how it dynamically shapes the global industry network. Thus, we contribute to closing the gap between social action at the micro level, organizational linkages at the meso level and the structure of global industry networks at the macro level.     

Parent–Child Emotional Communication and Children's Coping in Middle Childhood

Parent–child communication regarding children's negative emotions and coping were examined in a sample of 75 5th graders (53% boys) and their mothers and fathers. We predicted that emotionally open communication between a parent and his or her child would be related to children's use of constructive coping strategies. Parents reported on how they react to their child's negative emotions, and children reported on how much they share their negative feelings with each parent. Additionally, emotional communication was measured during a parent–child discussion task involving an event that was upsetting to the child. The results indicated that emotional communication, as reported by mothers, fathers, and children, as well as mother–child observed communication, were related to children's coping strategies. The findings point to a need to assess emotional communication using multiple measures that tap both the child's and the parents’ perspectives and that use different methodologies.     

Quantitative models for optimal rest period scheduling

Mathematical and simulation models studying work-rest schedules in a production process are developed to arrive at an optimal rest policy to maximize work output per unit time. A CSMP simulation study is used to test the sensitivity of the results for different specific cases.
