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.}, language = {de} } @article{MatthiasRisslingPieperetal.2020, author = {Matthias, Katja and Rissling, Olesja and Pieper, Dawid Aleksander and Morche, Johannes and Nocon, Marc and Jacobs, Anja and Wegewitz, Uta Elke and Schirm, Jaqueline and Lorenz, Robert C.}, title = {The methodological quality of systematic reviews on the treatment of adult major depression needs improvement according to AMSTAR 2}, series = {Heliyon}, volume = {6}, journal = {Heliyon}, number = {9}, publisher = {Elsevier}, address = {London [u.a.]}, issn = {2405-8440}, doi = {10.1016/j.heliyon.2020.e04776}, pages = {7}, year = {2020}, abstract = {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.}, language = {en} } @article{TomaszewskaSchuster2021, author = {Tomaszewska, Paulina and Schuster, Isabell}, title = {Prevalence of teen dating violence in Europe}, series = {New directions for child and adolescent development}, volume = {178}, journal = {New directions for child and adolescent development}, number = {Special Issue: Prevalence and predictors of teen dating violence: a European perspective}, publisher = {Jossey-Bass}, address = {San Francisco}, issn = {1534-8687}, doi = {10.1002/cad.20437}, pages = {11 -- 37}, year = {2021}, abstract = {Violence in adolescent relationships is a common problem with numerous negative short- and long-term consequences.

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.

The capability of primary producers to defend themselves against herbivores affects their own survival, can modulate the strength of trophic cascades and changes rates of competitive exclusion in aquatic communities. Algal species are highly flexible in their morphology, growth form, biochemical composition and production of toxic and deterrent compounds. Several of these variable traits in phytoplankton have been interpreted as defence mechanisms against grazing. Zooplankton feed with differing success on various phytoplankton species, depending primarily on size, shape, cell wall structure and the production of toxins and deterrents. Chemical cues associated with (i) mechanical damage, (ii) herbivore presence and (iii) grazing are the main factors triggering induced defences in both marine and freshwater phytoplankton, but most studies have failed to disentangle the exact mechanism(s) governing defence induction in any particular species. Induced defences in phytoplankton include changes in morphology (e.g. the formation of spines, colonies and thicker cell walls), biochemistry (such as production of toxins, repellents) and in life history characteristics (formation of cysts, reduced recruitment rate). Our categorization of inducible defences in terms of the responsible induction mechanism provides guidance for future work, as hardly any of the available studies on marine or freshwater plankton have performed all the treatments that are required to pinpoint the actual cue(s) for induction. We discuss the ecology of inducible defences in marine and freshwater phytoplankton with a special focus on the mechanisms of induction, the types of defences, their costs and benefits, and their consequences at the community level.}, language = {en} } @misc{SchusterKrahe2016, author = {Schuster, Isabell and Krah{\´e}, Barbara}, title = {Abuse of Elders Living at Home: A Review of Recent Prevalence Studies}, series = {International Journal of Behavioral Science}, volume = {11}, journal = {International Journal of Behavioral Science}, publisher = {Behavioral Science Research Institute, Srinakharinwirot University}, address = {Bangkok}, issn = {1906-4675}, pages = {93 -- 108}, year = {2016}, abstract = {This article presents evidence from recent studies on the prevalence of different forms of elder abuse.

Wie kann eine vermehrte Verwendung von Ironie in der deutschen Berichterstattung das Denken und Sprechen {\"u}ber politisches Geschehen, die freie Meinungs- und Urteilsbildung bis hin zu Entscheidungsfindungen beeinflussen? Als Resultat der qualitativen Dokumentenanalyse wird letztlich ein operationalisiertes Schema konzipiert, welches die genaue Einordnung unterschiedlicher Einsatzm{\"o}glichkeiten von Ironie in den {\"o}ffentlichen Medien auf Textebene erlaubt und in ihrer argumentativen Funktion und komischen Wirkkraft den Einfluss identifiziert, den Ironie auf die jeweilige Sachdebatte nimmt. Um die zwiesp{\"a}ltige Rolle von Ironie im Sprachgebrauch genauer zu bestimmen, wo sie sowohl als n{\"u}tzliches Ausdrucksmittel f{\"u}r die Widerspr{\"u}chlichkeiten im komplexen gesellschaftspolitischen Geschehen als auch als Ohnmachtsreaktion auf deren Unaufl{\"o}sbarkeit erscheinen kann, n{\"a}hert sich die Arbeit der Ironie zun{\"a}chst {\"u}ber ihre epistemologische Geschichte und rhetorische Grunddefinition an. Ironie sagt immer etwas und zugleich etwas anderes. Sie er{\"o}ffnet somit ein Bedeutungsfeld in der Spannung verschiedener oder gar entgegengesetzter Pole und l{\"a}sst mehrere unvereinbare Interpretationen zu. Dieses besondere Stilmittel kann also zu einer differenzierten, multiperspektivischen Betrachtung genutzt werden. Oder aber gerade dazu, klare Positionen zu vermeiden und den R{\"u}ckzug in alternative Auslegungsm{\"o}glichkeit einer Aussage offen zu halten. Im Weiteren sind drei große, epochale Str{\"o}mungen zu unterscheiden, die in der Ironie eine umfassende Geisteshaltung und erkenntnistheoretische Position verstanden beziehungsweise entwickelt haben: Einzeln er{\"o}rtert werden die philosophische Verstellungstechnik der sokratischen Ironie, die poetisch-{\"a}sthetischen Darstellungsverfahren der romantischen Ironie sowie die kritische Selbstbetrachtung der modernen Ironie. Diese loten aus, ob sich eine ironische Geisteshaltung als differenzierte Ann{\"a}herung an die komplexe Wahrheit des Menschen oder im Gegenteil als irrationaler Flucht- oder Irrweg entpuppt. Die zweite S{\"a}ule der Analyse betrachtet die komische Wirkung von Ironie und die Bedeutung des Lachens f{\"u}r den Menschen, der als einziges Lebewesen zu solch einer Reaktion f{\"a}hig ist. Wann lacht der Mensch und was dr{\"u}ckt er damit aus: Hilflosigkeit an den Grenzen seines sozialen Verhaltensspektrums oder Souver{\"a}nit{\"a}t im Umgang mit einer ungewohnten Situation? Komik muss in ihrer medialen Anwendung von Unterhaltungskultur bis seri{\"o}ser Berichterstattung situiert und Ironie klar von anderen komischen Figuren wie der Satire oder dem Sarkasmus unterschieden werden. Ihrer komischen Komponente steht ihr Anteil am Tragischen gegen{\"u}ber, beide spielen zuweilen zusammen. Im R{\"u}ckbezug auf den Einfluss einer ironischen Sprachwahl oder Geisteshaltung auf die Rezension und damit auf die Wahrnehmung des politischen Geschehens finden sich beide Eingangsthesen best{\"a}tigt: Ironie kann hilfreiches Ausdrucksmittel oder Symptom gesellschaftlicher Ohnmacht sein. Rhetorisch dient sie als Kampfmittel im Politikdiskurs oder zur Ridik{\"u}lisierung der Gegenposition. Indem sie stets mehrere Bedeutungsebenen er{\"o}ffnet und andere oder gar gegens{\"a}tzliche Denk- und Seinsweisen zugleich in den Blick nimmt, hat Ironie das Potential, politische sowie kulturelle Ideale und Richtlinien neu in Frage zu stellen. In ihrer destruktiven Kraft, Widerspr{\"u}che anzuzeigen, steckt somit eine aufkl{\"a}rerische Funktion zur Entlarvung von Irrt{\"u}mern oder Erschließung alternativer Ans{\"a}tze. Andererseits kann eine Ironisierung in der Betrachtung und Bewertung von Politik auch auf den Wirklichkeits- oder Identit{\"a}tsverlust einer Gesellschaft hinweisen, wenn n{\"a}mlich die Lebensrealit{\"a}t angesichts g{\"a}nzlich unterschiedlicher, doch ebenso denkbarer Organisationsformen und Weltbilder ihre {\"U}berzeugungskraft einb{\"u}ßt. In der modernen Ironie bietet sich wiederum die Chance, diese Relativit{\"a}t von Werten und Normen als Schl{\"u}sselerlebnis der eigenen Zeit konstruktiv aufzugreifen. Das Unterfangen dieser Bachelorarbeit kulminiert darin, all jene diversen Arten und Ebenen von Ironie in einem einzigen Analyseschema nach operationalisierten Kriterien der Linguistik, Rhetorik, Literaturwissenschaft, Philosophie und {\"A}sthetik bestimmbar zu machen. Im zweiten Schritt wendet das Schema diese Forschungsergebnisse schließlich f{\"u}r eine politikwissenschaftliche Einordnung der Funktion und Wirkung von Ironie bei ihrer Verwendung in der {\"o}ffentlich-kritischen Politikrezension durch textbasierte Medien an. Hierin k{\"o}nnte ein erster Grundstein f{\"u}r eine politische Theorie der Ironie liegen.

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.}, language = {en} } @misc{BecherOsborneThorbeketal.2013, author = {Becher, Matthias A. and Osborne, Juliet L. and Thorbek, Pernille and Kennedy, Peter J. and Grimm, Volker}, title = {Towards a systems approach for understanding honeybee decline - a stocktaking and synthesis of existing models}, series = {Journal of applied ecology : an official journal of the British Ecological Society}, volume = {50}, journal = {Journal of applied ecology : an official journal of the British Ecological Society}, number = {4}, publisher = {Wiley-Blackwell}, address = {Hoboken}, issn = {0021-8901}, doi = {10.1111/1365-2664.12112}, pages = {868 -- 880}, year = {2013}, abstract = {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.}, language = {en} } @article{HeinzelLawrenceKalliesetal.2015, author = {Heinzel, Stephan and Lawrence, Jimmy B. and Kallies, Gunnar and Rapp, Michael Armin and Heissel, Andreas}, title = {Using Exercise to Fight Depression in Older Adults}, series = {GeroPsych : the journal of gerontopsychology and geriatric psychiatry}, volume = {28}, journal = {GeroPsych : the journal of gerontopsychology and geriatric psychiatry}, publisher = {Hogrefe}, address = {Cambridge, Mass. ; G{\"o}ttingen [u.a.]}, issn = {1662-9647}, doi = {10.1024/1662-9647/a000133}, pages = {149 -- 162}, year = {2015}, abstract = {Depression is the most prevalent psychiatric disorder in the general population.

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.}, language = {en} }
