BackgroundSocial adversities are accepted as critical factors in the development of psychopathology in young people, but the precise mechanisms of this relationship are unknown.AimsTo explore sources of evidence and suggest future lines of research to clarify the relationship between exposure to negative circumstances and development of psychopathology in young people.MethodSelective survey of the literature to collect a series of hypotheses that might serve as a framework for future research.Results and conclusionsEvidence to date suggests there is no simple relationship between adverse life events and the subsequent emergence of psychopathology. The interplay of acute and chronic stressors over the lifespan with affective temperament; the interrelationship of ‘sensitivity’ and ‘performance’ cognitions in response to life events; and limbic-cortical neural networks are all indicated as important avenues of future research.

The Relationship

Despite the continuous interest in studying entrepreneurial teams, the relationship between team composition and, particularly, team diversity and performance remains fertile ground for active debate. Taking roots in the knowledge-based view and organizational learning literatures, this chapter argues that performance in entrepreneurial teams is contingent on (a) the overlap between team members’ knowledge/competences and the content of the performed tasks, (b) the duplication of the team members’ knowledge in the areas with that content, (c) the nature of tasks (exploration or exploitation), (d) the team’s flexibility to adapt to changes in the content and nature of those tasks, and (e) the rate of environmental change. Because an important source of ambiguity in the understanding of how team diversity and performance are linked ties to issues of how team diversity is conceptualized and operationalized, the chapter also proposes a new way of looking at diversity in future research.

Changes are a common phenomenon in the construction industry, impacting the project's cost, time, and performance. The purpose of this work is to a comprehensive review relating to variation order causes. Also, the aim here is to determine variation order causes in the building’s construction. More importantly, explore the relationship between these causes. However, the importance of specifying the causes for change orders is the first step in managing variation orders to reduce the harmful effect on a project. The field survey was conducted for several institutions such as health (Karkh’s health), higher education (University of Baghdad and University of Kufa). As a result, a field visit was made to the project sites. They were then, Conducting interviews with the resident engineer, the consultant, and the contractor. A developer tool called cause (variation orders) breakdown structure (CBS) included 12 causes at the first level, including 103 sub-causes. There is a relationship between the variation orders causes, which is evident in the third level. The study recommends adopting (CBS) a comprehensive reference for variation order causes in projects due to facilitating their management processes. Future research could examine the relative importance of variation order causes, in addition to using a fuzzy cognitive map to find the extent of each cause’s influence on the other.

The purpose of this study is to examine whether subordinate attribution style on leader emotional (positive and negative) display moderates the relationship between subordinate achievement motivation/personal need for structure(PNS) and performance. 75 employees in the sales department of a pharmaceutical company participated in the survey. Results showed that subordinates using person-attribution style on leader negative emotional display performed better than those using performance-attribution style, though they had the same high level of explicit achievement motivation and PNS. That is, the moderating role of subordinate attributional style on leader negative emotional display was verified. On the contrary, subordinate attributional style on leader positive emotional display did not moderate the relationship between subordinate explicit achievement motivation/PNS and performance. Theoretical and practical implications, limitations, and future research are discussed.

Background Fatigue in baseball pitchers is a process linked to lowered physical and mental performance, injury, and changes in kinematics. Numerous studies have associated fatigue with overuse, high ball velocities, lack of rest time, poor mechanics, and degree of self-satisfaction. The aim of this study was to systematically review the literature to identify a theoretical framework for the relationship between outcomes and the manifestation of fatigue on baseball pitching. The synthesized data may identify areas requiring further research. Methodology This protocol was registered with PROSPERO (ID: CRD42018114194). SPORTDiscus, Medline, PubMed, Cochrane Database of Systematic Reviews, and Google Scholar were searched, using keywords such as fatigue in pitchers and changes in kinematics (e.g., pitching mechanics, valgus elbow torque), performance (e.g., pitch count, pitch type), and injury (e.g., pain, elbow, and shoulder soreness). Three reviewers independently screened the articles, selected relevant literature based on abstract eligibility, and assessed the methods described therein for final inclusion. Results A total of 31,860 articles were screened for eligibility and 25 articles were included for the review. The selected articles included epidemiological, longitudinal, experimental, conference papers, and crossover laboratory studies. Evidence extracted from the 25 studies demonstrates a relationship between fatigue in baseball pitching, and three overarching outcomes: changes in kinematics, a decrease in performance, and an increase in injury risk. Conclusions Findings show that a co-dependence between changes in kinematics and a decrease in performance, which stems from central and peripheral fatigue, is a contributing factor of injury in baseball pitchers. A large percentage of baseball pitchers exhibit pain or soreness in either their elbow or shoulder, or both at some point in a season. Initially, kinematic changes occur that could maintain performance, but may increase joint and tissue loading. Performance decreased with elevated pitch counts and innings thrown, and pitching further into games or the season. Evidence was found to be consistent across all studies; however, more work is needed in the area of fatigue as an injury mechanism during pitching. With a proof of concept established, the prevention of negative outcomes associated with fatigue must be the focus of future research and performance should not be the only criteria.

Previous research has indicated that playing violent video games may be associated with an increase in acceptance of violence and positive attitudes towards perpetrators of crime. This study is the first to investigate the relationship between playing violent video games and attitudes towards victims of crime. A total of 206 young people (aged 12-24 years) completed measures of attitudes towards victims and violent video game exposure. The results suggest that exposure to violent video games is associated with less concern being reported for victims of crime. Young people who play more violent video games reported less concern for general victims and for culpable victims, and these effects cannot be explained by gender or age differences. The results are discussed in relation to relevant research in the area, along with recommendations for future research.

PurposeWith the rise of service economy, many companies are attempting to gain a competitive advantage through service innovation. However, the existing research has not drawn consistent conclusions about the relationship between service innovation and firm performance. Hence, the purpose of this paper is to provide a quantitative review on the service innovation-performance relationship based on research findings reported in the extant literature.Design/methodology/approachStudies from 46 peer-reviewed articles were sampled and analyzed. A meta-analytic approach was adopted to conduct a quantitative review on the relationship between service innovation and firm performance, and the effects of any potential moderators were further explored.FindingsThe results found that service innovation has a significant positive impact on firm performance. Additionally, the relationship between service innovation and firm performance is influenced by measurement moderators (economic region and performance measurement), and contextual moderators (firm type, innovation type, customer factors and attitudes toward risk).Originality/valueThe meta-analysis has been used to explore the relationship between service innovation and firm performance, and the findings have contributed to the literature on service innovation, as well as providing future research directions.

Feedback is information made available to employees in their work environment, whereas feedback-seeking behaviors (FSBs) help employees to evaluate proactively whether their work has met performance standards and their behavior is considered appropriate. Prior studies have provided a perspective on how the feedback-seeking contexts affect the emergence and development of FSBs. In this study, we extend that perspective by investigating when FSBs affect job performance so that we can understand whether more feedback seeking is always better. Adopting the relational view of leadership, we hypothesize that the FSB-performance relationship should be stronger for employees with low leader-member exchange (LMX) and in groups with low aggregate LMX and low LMX differentiation. Using a multilevel research design and a sample of 379 teachers in 25 groups, we find support for most of our hypotheses. We discuss the implications of the study for the FSB and the proactive behavior literature and suggest avenues for future research.

THIS IS A PRE-PRINT OF AN ARTICLE PUBLISHED IN "FRONTIERS IN PSYCHIATRY - SPECIAL ISSUE: RESILIENCE, LIFE EVENTS, TRAJECTORIES AND THE BRAIN (9: 230)". THE FINAL AUTHENTICATED VERSION IS AVAILABLE ONLINE AT: https://doi.org/10.3389/fpsyt.2018.00230Background: Up to half of Western children and adolescents experience at least one type of childhood adversity. Individuals with a history of childhood adversity have an increased risk of psychopathology. Resilience enhancing factors reduce the risk of psychopathology following childhood adversity. A comprehensive overview of empirically supported resilience factors is critically important for interventions aimed to increase resilience in young people. Moreover, such an overview may aid the development of novel resilience theories. Therefore, we conducted the first systematic review of social, emotional, cognitive and/ or behavioural resilience factors after childhood adversity.Methods: We systematically searched Web of Science, PsycINFO and Scopus (e.g. including MEDLINE) for English, Dutch and German literature. We included cohort studies that examined whether a resilience factor was a moderator and/ or a mediator for the relationship between childhood adversity and psychopathology in young people (mean age 13-24). Therefore, studies were included if the resilience factor was assessed prior to psychopathology, and childhood adversity was assessed no later than the resilience factor. Study data extraction was based on the STROBE report and study quality was assessed with an adapted version of Downs and Black’s scale. The preregistered protocol can be found at: http://www.crd.york.ac.uk/PROSPERO/display_record.asp?ID=CRD42016051978.Results: The search identified 1969 studies, of which 22 were included (eight nationalities, study sample n range: 59-6780). We found empirical support for 13 of 25 individual-level (e.g. high self-esteem, low rumination), six of 12 family-level (e.g. high family cohesion, high parental involvement), and one of five community-level resilience factors (i.e. high social support), to benefit mental health in young people exposed to childhood adversity. Single versus multiple resilience factor models supported the notion that resilience factors should not be studied in isolation, and that interrelations between resilience factors should be taken into account when predicting psychopathology after childhood adversity.Conclusions: Interventions that improve individual, family, and/ or social support resilience factors may reduce the risk of psychopathology following childhood adversity. Future research should scrutinize whether resilience factors function as a complex interrelated system that benefits mental health resilience after childhood adversity.
