In this paper, we compare three important frameworks of generalized transitivity: g-stochastic transitivity, T-transitivity, and cycle-transitivity. To this end, we introduce E-transitivity as an even more general notion. We also use this framework to extend an existing hierarchy of different types of transitivity. As an illustration, we study transitivity properties of probabilities of pairwise preferences, which are induced as marginals of an underlying probability distribution on rankings (strict total orders) of a set of alternatives.

This RCT examined the effect of an untreated vitamin D deficiency compared to an immediate vitamin D3 supplementation on depression scores in children and adolescents during standard day and in-patient psychiatric treatment. Methods Patients with vitamin D deficiency [25(OH)D ≤ 30 nmol/l] and at least mild depression [Beck Depression Inventory II (BDI-II) > 13] (n = 113) were 1:1 randomized into verum (VG; 2640 IU vitamin D3/d) or placebo group (PG) in a double-blind manner. During the intervention period of 28 days, both groups additionally received treatment as usual. BDI-II scores were assessed as primary outcome, DISYPS-II (Diagnostic System for Mental Disorders in Childhood and Adolescence, Self- and Parent Rating) and serum total 25(OH)D were secondary outcomes. Results At admission, 49.3% of the screened patients (n = 280) had vitamin D deficiency. Although the intervention led to a higher increase of 25(OH)D levels in the VG than in the PG (treatment difference: + 14 ng/ml; 95% CI 4.86–23.77; p = 0.003), the change in BDI-II scores did not differ (+ 1.3; 95% CI − 2.22 to 4.81; p = 0.466). In contrast, DISYPS parental ratings revealed pronounced improvements of depressive symptoms in the VG (− 0.68; 95% CI − 1.23 to − 0.13; p = 0.016). Conclusion Whereas this study failed to show a vitamin D supplementation effect on self-rated depression in adolescent in- or daycare patients, parents reported less depressive symptoms in VG at the end of our study. Future trials should consider clinician-rated depressive symptoms as primary outcome.

Whey protein plus potassium bicarbonate diet-supplementation (NUTR) could attenuate this effect by improving oxidative metabolism. We evaluated the impact of 21-day BR and NUTR on fatigue resistance of plantar flexor muscles (PF) during repeated shortening contractions, and whether any change was related to altered energy metabolism and muscle oxygenation. Methods Ten healthy men received a standardized isocaloric diet with (n = 5) or without (n = 5) NUTR. Eight bouts of 24 concentric plantar flexions (30 s each bout) with 20 s rest between bouts were employed. PF muscle size was assessed by means of peripheral quantitative computed tomography. PF muscle volume was assessed with magnetic resonance imaging. PF muscle force, contraction velocity, power and surface electromyogram signals were recorded during each contraction, as well as energy metabolism (31P nuclear magnetic resonance spectroscopy) and oxygenation (near-infrared spectroscopy). Cardiopulmonary parameters were measured during an incremental cycle exercise test. Results BR caused 10–15% loss of PF volume that was partly recovered 3 days after re-ambulation, as a consequence of fluid redistribution. Unexpectedly, PF fatigue resistance was not affected by BR or NUTR. BR induced a shift in muscle metabolism toward glycolysis and some signs of impaired muscle oxygen extraction. NUTR did not attenuate the BR-induced-shift in energy metabolism. Conclusions Twenty-one days’ BR did not impair PF fatigue resistance, but the shift to glycolytic metabolism and indications of impaired oxygen extraction may be early signs of developing reduced muscle fatigue resistance. }}, author = {{Bosutti, Alessandra and Mulder, Edwin and Zange, Jochen and Bühlmeier, Judith and Ganse, Bergita and Degens, Hans}}, issn = {{1439-6319}}, journal = {{European Journal of Applied Physiology}}, keywords = {{Physiology (medical), Public Health, Environmental and Occupational Health, Orthopedics and Sports Medicine, General Medicine, Public Health, Environmental and Occupational Health, Physiology}}, number = {{5}}, pages = {{969--983}}, publisher = {{Springer Science and Business Media LLC}}, title = {{{Effects of 21 days of bed rest and whey protein supplementation on plantar flexor muscle fatigue resistance during repeated shortening contractions}}}, doi = {{10.1007/s00421-020-04333-5}}, volume = {{120}}, year = {{2020}}, } @article{27018, abstract = {{Acute anorexia nervosa (AN) constitutes an extreme physiological state.

Die Relevanz von Peers für die Entwicklung von Jugendlichen konnte in verschiedenen Studien bereits bestätigt werden. Im Unterricht zeigt sich dies u.a. durch höhere situative Motivation und Freude sowie geringerem Stressempfinden während sozialer Interaktionen mit Mitschülerinnen und -schülern verglichen mit Einzelarbeitssituationen. Allerdings stellte sich auch heraus, dass Jugendliche mit Verhaltensauffälligkeiten Schwierigkeiten im Knüpfen und Aufrechterhalten von sozialen Kontakten und Freundschaften haben. Während in bisherigen Studien Verhalten als dichotome Variable untersucht wurde, wird hier ein dimensionaler, personzentrierter Ansatz zur Identifizierung von Gruppen mit heterogenen Verhaltensweisen verfolgt. Ziel dieses Beitrags ist daher die Untersuchung von Effekten sozialer Interaktionen im Unterricht auf das emotionale Erleben von Jugendlichen mit heterogenen Verhaltensweisen. Zudem wird ein möglicher Moderationseffekt der Klassenkomposition in Bezug auf das Verhalten überprüft. Hierzu wurden N = 719 Schülerinnen und Schülern der fünften und sechsten Jahrgangsstufe unter Verwendung der experience sampling method zu zwei bis drei Messzeitpunkten pro Tag an fünf aufeinanderfolgenden Schultagen zu ihrem aktuellen emotionalen Erleben und ihrem sozialen Kontext befragt. Insgesamt lagen 8870 „Momentaufnahmen“ des emotionalen Erlebens und von Unterrichtssituationen vor. Auf der Grundlage von Verhaltenseinschätzungen durch Lehrpersonen wurden mittels latenter Profilanalysen drei Profiltypen innerhalb der Schülerschaft identifiziert: Jugendliche mit adaptivem, internalisierendem und externalisierendem Verhalten. Ergebnisse von Multilevel-Strukturgleichungsmodellen zeigen, dass Jugendliche in Unterrichtssituationen, in denen sie mit ihren Peers interagieren (z.B. in Partner- oder Gruppenarbeiten), motivierter und weniger gestresst sind als in Einzelsituationen. Für Jugendliche mit externalisierendem oder internalisierendem Verhalten ist dieser Effekt stärker ausgeprägt. Die geringfügigen, jedoch nicht signifikanten differenziellen moderierenden Effekte verweisen zudem darauf, dass der Zusammenhang des emotionalen Erlebens und der Peerinteraktionen für Jugendliche nicht durch ihr Klassenumfeld in Bezug auf prosoziales oder problematisches Verhalten moderiert wird. Die Ergebnisse werden sowohl methodisch als auch inhaltlich diskutiert, unter anderem in Bezug auf die Frage, ob und inwiefern Peers Quellen aktueller Motivation im Unterricht darstellen. }}, author = {{Knickenberg, Margarita and Zurbriggen, Carmen and Schmidt, Philipp}}, issn = {{1010-0652}}, journal = {{Zeitschrift für Pädagogische Psychologie}}, keywords = {{Developmental and Educational Psychology}}, pages = {{1--15}}, publisher = {{Hogrefe Publishing Group}}, title = {{{Peers als Quelle aktueller Motivation?}}}, doi = {{10.1024/1010-0652/a000292}}, year = {{2020}}, } @article{33436, abstract = {{Wir freuen uns, das zweite Jahresheft der HLZ vorlegen zu können.
