Körperliche Aktivität in der Prävention und Behandlung von Essstörungen
No full textAuf der einen Seite stellt exzessive oder mangelnde körperliche Aktivität ein phänomenologisches Merkmal von Essstörungen dar und ist ein wesentlicher ätiologischer Faktor. Auf der anderen Seite hat eine gesunde, angepasste körperliche Aktivität das Potenzial, die Wirksamkeit von präventiven und therapeutischen Massnahmen im Bereich der Essstörungen zu unterstützen. Es liegen Studienergebnisse vor, die den Nutzen von Interventionen mit Fokus auf die körperliche Aktivität als Ergänzung zur Psychotherapie bestätigen und aufzeigen, dass professionell geplante und begleitete Interventionen dieser Art nicht kontraproduktiv oder gefährlich sind, sondern das Behandlungsergebnis positiv beeinflussen können. Die aktuelle Studienlage erlaubt eine vorläufige Formulierung von Handlungsleitlinien zur Einbettung von körperlicher Aktivität als Ergänzung von evidenzbasierten Behandlungsansätzen. Fokus der Interventionen ist der Abbau von ungesunder, exzessiver und der Aufbau von flexibler körperlicher Aktivität.On the one hand, excessive or insufficient physical activity is a phenomenological feature and an important etiological factor in eating disorders. On the other hand, healthy and adaptive physical activity has the potential to support the effectiveness of preventive and therapeutic interventions for eating disorders. Research findings confirm the usefulness of interventions focusing on physical activity as an add-on to psychotherapy. Professionally planned and accompanied interventions of this kind are not counterproductive or dangerous but can have a positive effect on the treatment outcome. The current state of research allows a preliminary formulation of guidelines to embed physical activity interventions into evidence-based treatment approaches. The focus of such interventions lies on the reduction of unhealthy, excessive physical activity and the promotion of flexible physical activity
The human source memory system struggles to distinguish virtual reality and reality
Full text linkVirtual Reality (VR) is used in a variety of fields with the goal to increase ecological validity compared to traditional monitor-based setups. Here we report additional evidence for the adequacy of this research strategy. In a memory confusion paradigm spanning over stimuli presentation in reality, VR and on a computer monitor, participants were more prone to confusing reality with VR than with a traditional monitor-based setup, indicating a relative proximity of experiences in VR and reality. We speculate that the human source memory's difficulty in distinguishing VR from reality may provide a basis for the good generalizability of treatment effects in VR to daily life. At the same time, the effect may demonstrate a potential danger of a mindless use of VR technology
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Attention to faces in images is associated with personality and psychopathology.
Full text linkHumans show a robust tendency to look at faces in images, but also differ consistently in the strength of this attentional preference. Previous research remained inconclusive as to how a stronger face preference may be indicative of an individual's personality or clinical characteristics. Here we investigated face preferences in 120 participants (primarily drawn from a student population) who freely viewed photos in an internet browser showing a person in the context of a visually rich environment while attention was assessed using a cursor-based technique. Participants differed consistently in the strength of their face preference across images. A stronger preference for faces was correlated positively with openness to experience, extraversion, agreeableness and empathizing and was correlated negatively with social anxiety, depression levels and alexithymia. Trait measures were linked through a strong common factor which was additionally correlated with face preference. We conclude that face preferences may be linked to personality traits and to psychopathology but that an attribution to a specific facet of psychopathology may not be warranted. Future research should investigate links between face preferences and personality features in more diverse samples and across differing social situations
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
