A1 - Grimm, Volker T1 - Towards a systems approach for understanding honeybee decline - a stocktaking and synthesis of existing models JF - Journal of applied ecology : an official journal of the British Ecological Society N2 - 1. The health of managed and wild honeybee colonies appears to have declined substantially in Europe and the United States over the last decade. Sustainability of honeybee colonies is important not only for honey production, but also for pollination of crops and wild plants alongside other insect pollinators. A combination of causal factors, including parasites, pathogens, land use changes and pesticide usage, are cited as responsible for the increased colony mortality. 2. However, despite detailed knowledge of the behaviour of honeybees and their colonies, there are no suitable tools to explore the resilience mechanisms of this complex system under stress. Empirically testing all combinations of stressors in a systematic fashion is not feasible. We therefore suggest a cross-level systems approach, based on mechanistic modelling, to investigate the impacts of (and interactions between) colony and land management. 3. We review existing honeybee models that are relevant to examining the effects of different stressors on colony growth and survival. Most of these models describe honeybee colony dynamics, foraging behaviour or honeybee - varroa mite - virus interactions. 4. We found that many, but not all, processes within honeybee colonies, epidemiology and foraging are well understood and described in the models, but there is no model that couples in-hive dynamics and pathology with foraging dynamics in realistic landscapes. 5. Synthesis and applications. We describe how a new integrated model could be built to simulate multifactorial impacts on the honeybee colony system, using building blocks from the reviewed models. The development of such a tool would not only highlight empirical research priorities but also provide an important forecasting tool for policy makers and beekeepers, and we list examples of relevant applications to bee disease and landscape management decisions.

A1 - Krahé, Barbara A1 - Zinzow, Heidi T1 - The global prevalence of sexual assault BT - a systematic review of international research since 2010 JF - Psychology of violence N2 - Objective: We present a review of peer-reviewed English-language studies conducted outside the United States and Canada on the prevalence of sexual assault victimization in adolescence and adulthood published since 2010. Method: A systematic literature search yielded 32 articles reporting on 45 studies from 29 countries. Studies that only provided prevalence estimates for sexual assault in intimate relationships or did not present separate rates for men and women were excluded. All studies were coded by two coders, and a risk of bias score was calculated for each study. Both past-year and prevalence rates covering longer periods were extracted. Results: The largest number of studies came from Europe (n = 21), followed by Africa (n = 11), Asia, and Latin America (n = 6 each). One study came from the Middle East and no studies were found from Oceania. Across the 22 studies that reported past-year prevalence rates, figures ranged from 0% to 59.2% for women, 0.3% to 55.5% for men, and 1.5% to 18.2% for lesbian, gay, bisexual, and transgender (LGBT) samples. The average risk of bias score was 5.7 out of 10. Studies varied widely in methodology. Conclusion: Despite regional variation, most studies indicate that sexual assault is widespread. More sustained, systematic, and coordinated research efforts are needed to gauge the scale of sexual assault in different parts of the world and to develop prevention measures.

A1 - Heissel, Andreas T1 - Using Exercise to Fight Depression in Older Adults BT - A Systematic Review and Meta-Analysis JF - GeroPsych : the journal of gerontopsychology and geriatric psychiatry N2 - Depression is the most prevalent psychiatric disorder in the general population. Despite a large demand for efficient treatment options, the majority of older depressed adults does not receive adequate treatment: Additional low-threshold treatments are needed for this age group. Over the past two decades, a growing number of randomized controlled trials (RCT) have been conducted, testing the efficacy of physical exercise in the alleviation of depression in older adults. This meta-analysis systematically reviews and evaluates these studies; some subanalyses testing specific effects of different types of exercise and settings are also performed. In order to be included, exercise programs of the RCTs had to fulfill the criteria of exercise according to the American College of Sports Medicine, including a sample mean age of 60 or above and an increased level of depressive symptoms. Eighteen trials with 1,063 participants fulfilled our inclusion criteria. A comparison of the posttreatment depression scores between the exercise and control groups revealed a moderate effect size in favor of the exercise groups (standardized mean difference (SMD) of –0.68, p < .001). The effect was comparable to the results achieved when only the eleven trials with low risk of bias were included (SMD = –0.63, p < .001). The subanalyses showed significant effects for all types of exercise and for supervised interventions. The results of this meta-analysis suggest that physical exercise may serve as a feasible, additional intervention to fight depression in older adults. However, because of small sample sizes of the majority of individual trials and high statistical heterogeneity, results must be interpreted carefully.

A1 - Fotopoulou, Aikaterini T1 - The social modulation of pain - others as predictive signals of salience ; a systematic review JF - Frontiers in human neuroscienc N2 - Several studies in cognitive neuroscience have investigated the cognitive and affective modulation of pain. By contrast, fewer studies have focused on the social modulation of pain, despite a plethora of relevant clinical findings. Here we present the first review of experimental studies addressing how interpersonal factors, such as the presence, behavior, and spatial proximity of an observer, modulate pain. Based on a systematic literature search, we identified 26 studies on experimentally induced pain that manipulated different interpersonal variables and measured behavioral, physiological, and neural pain-related responses. We observed that the modulation of pain by interpersonal factors depended on (1) the degree to which the social partners were active or were perceived by the participants to possess possibility for action; (2) the degree to which participants could perceive the specific intentions of the social partners; (3) the type of pre-existing relationship between the social partner and the person in pain, and lastly, (4) individual differences in relating to others and coping styles. Based on these findings, we propose that the modulation of pain by social factors can be fruitfully understood in relation to a recent predictive coding model, the free energy framework, particularly as applied to interoception and social cognition. Specifically, we argue that interpersonal interactions during pain may function as social, predictive signals of contextual threat or safety and as such influence the salience of noxious stimuli. The perception of such interpersonal interactions may in turn depend on (a) prior beliefs about interpersonal relating and (b) the certainty or precision by which an interpersonal interaction may predict environmental threat or safety.

To improve patient care and to foster research, a clear distinction between the various concepts of chronicity cited in the literature is crucial. The aim was thus to explicate central concepts related to courses and trajectories in OCD based on an explorative, scoping search of the existing literature. Our review revealed a considerable lack in content validity, as the concepts were operationalized inconsistently. Concepts related to symptom improvement were (complete) recovery, partial/full remission and partial/full response. Terms used in relation with symptom stability or worsening were chronic/continuous, intermittent and episodic course, waxing and waning, relapse, recurrence, deterioration and treatment-refractoriness. All concepts are explained and visualized as a result of the review. Further, based on authors' remarks, we present recommendations on how to enhance care for chronic OCD patients, namely training psychotherapists to apply CBT as intended, managing patient beliefs about disease and treatment, and adapting psychotherapy to OCD subtypes. Finally, we then propose a literature-based definition of treatment-refractory OCD.

Schlussfolgerungen:Notwendig sind weitere methodisch hochwertige Studien, experimentell orientiert oder in der klinischen Praxis, die die Supervisionsforschung bereichern können. N2 - Background:Supervision plays a central role for the acquisition of therapeutic knowledge and competence and for quality control. Objective:The study aimed at mapping the current evidence regarding cognitive–behavioral supervision, and drawing conclusions for future research. Method:For evidence synthesis, we conducted a scoping review to outline key concepts, the current evidence, and potential gaps in research. In addition to a systematic literature search, forward and backward search strategies were implemented. Results:We included 12 publications on 10 empirical studies. All studies referred to education and training, but only a few examined exercises (e. g., role plays). Mostly, outcomes were evaluated subjectively, and study quality varied. Conclusion:Further methodologically sound studies, experimentally oriented or in clinical care, may support research.

T1 - The methodological quality of systematic reviews on the treatment of adult major depression needs improvement according to AMSTAR 2 BT - a cross-sectional study JF - Heliyon N2 - Background: Several standards have been developed to assess methodological quality of systematic reviews (SR). One widely used tool is the AMSTAR. A recent update -AMSTAR 2 -is a 16 item evaluation tool that enables a detailed assessment of SR that include randomised (RCT) or non-randomised studies (NRS) of healthcare interventions. Methods: A cross-sectional study of SR on pharmacological or psychological interventions in major depression in adults was conducted. SR published during 2012-2017 were sampled from MEDLINE, EMBASE and the Cochrane Database of SR. Methodological quality was assessed using AMSTAR 2. Potential predictive factors associated with quality were examined. Results: In rating overall confidence in the results of 60 SR four reviews were rated "high", two were "moderate", one was "low" and 53 were "critically low". The mean AMSTAR 2 percentage score was 45.3% (standard deviation 22.6%) in a wide range from 7.1% to 93.8%. Predictors of higher quality were: type of review (higher quality in Cochrane Reviews), SR including only randomized trials and higher journal impact factor. Limitations: AMSTAR 2 is not intended to be used for the generation of a percentage score. Conclusions: According to AMSTAR 2 the overall methodological quality of SR on the treatment of adult major depression needs improvement. Although there is a high need for summarized information in the field of mental health, this work demonstrates the need to critically assess SR before using their findings. Better adherence to established reporting guidelines for SR is needed.

N2 - Who is a high achiever? Operationalisation of high achievement in empirical educational research since the year 2000 Abstract. In recent years, high-achieving students have received increased attention by researchers, policymakers and practitioners. However, the question of what exactly constitutes high academic achievement is not yet agreed upon by the research community. This paper provides a systematic review of how researchers studying high-achieving students since 2000 have operationalized high academic achievement in their research. In particular, we examined which performance indicators were used, whether achievement was conceived of as subject-specific or general, and which cut-off values and comparison standards were applied. The systematic database search yielded N = 309 articles, n = 55 of which were finally included in the analysis. The present study observed a diversity in the operationalization of performance. The most commonly used indicators of performance were grades and test scores, with cross-domain and subject-specific definitions both being common. Some of the studies' cut-off values were difficult to compare, but in instances where a population norm could be derived, the median proportion of high achievers was 10 percent. The study discusses that constraints on generalizability and comparability between different studies on high achievers can arise due to methodological differences. This paper concludes with recommendations for the operationalization of high achievement. N2 - Leistungsstarke Kinder und Jugendliche sind in den letzten Jahren zunehmend in den Fokus der Bildungspolitik und der Bildungsforschung gerückt. Allerdings gibt es in der Forschung bislang kein geteiltes Verständnis darüber, was genau unter akademischer Leistungsstärke zu verstehen ist. Die vorliegende Arbeit gibt einen systematischen Überblick darüber, wie Forschende, die seit dem Jahr 2000 die Gruppe der leistungsstarken Schülerinnen und Schüler erforschten, Leistungsstärke in ihren Studien operationalisiert haben. Dabei wurde insbesondere untersucht, welche Leistungsindikatoren genutzt wurden, ob ein spezifischer Fachbezug hergestellt wurde und welche Cut-off-Werte und Vergleichsmaßstäbe angelegt wurden. Die systematische Datenbanksuche lieferte insgesamt N = 309 Artikel, von denen n = 55 die Einschlusskriterien erfüllten. Die Ergebnisse zeigen, dass eine große Vielfalt in der Operationalisierung von Leistungsstärke vorliegt. Die meistgenutzten Leistungsindikatoren waren Noten und Testwerte, wobei fächerübergreifende und fachspezifische Definitionen beide häufig waren. Die Cut-off-Werte der Studien waren zum Teil schwierig vergleichbar, aber dort, wo ein Populationsbezug hergestellt werden konnte, lag der Median des Populationsanteils Leistungsstarker bei 10 Prozent. Die Studie diskutiert methodische und inhaltliche Rahmenbedingungen, welche sich auf die Operationalisierung von Leistungsstärke und ihre Vergleichbarkeit über Studien hinweg auswirken. Die vorliegende Arbeit schließt mit Empfehlungen zur Operationalisierung von Leistungsstärke. T2 - Who is a high achiever?
