Background: Exercise procrastination is prevalent among college students, causing decline in phy.ical fitness. It is imperative to investigate the mechanism affecting college students’ phy.ical activity.behaviors. This study.was aimed at investigating the effect of procrastination on college students’ phy.ical exercise behavior, and the chain mediation effects of exercise commitment and action control (AC), to provide a theoretical basis for interventions targeting phy.ical exercise behavior among college students. Methods: A questionnaire survey.was conducted using convenience sampling. The General Procrastination Scale, Exercise Commitment Scale, Action Control Scale, and Phy.ical Activity.Rating Scale-3 questionnaires were used. Participants were 581 college students (age 19.27 ± 0.94 y.ars; 243 males and 338 females). Statistical methods of regression analy.is and structural equation modeling (SEM) were applied. Results: Procrastination, exercise commitment, and action control were found to be significant predictors of phy.ical exercise behavior. Among these predictors, exercise commitment and action control showed full mediation effects in the relationship between procrastination and phy.ical exercise behavior, and explained 25.48% and 30.77% of the total variance, respectively. The chain mediation effect of exercise commitment-action control was significant, accounting for 22.60% of the total variance, and the total indirect effect was 79.33%. Conclusion: Therefore, higher procrastination was associated with less participation in phy.ical exercise behavior among college students. Improvements in exercise commitment and volitional decision-making ability.for phy.ical exercise behavior promoted phy.ical exercise behavior, and increased exercise commitment promoted volitional decision-making ability.among the students. The chain reaction effect of exercise commitment and action control also buffered the negative effects of procrastination on phy.ical exercise beh

Background: Adolescent anxiety.has a significant impact on phy.ical and mental health, and overparenting is recognized as one of the major factors affecting adolescent anxiety. The objective of this study.was to investigate the relationship between overparenting and adolescent anxiety. while also examining the mediating role of cognitive avoidance. Methods: Data were collected through a cross-sectional survey.with 1931 valid responses using the Overparenting Scale, the Cognitive Avoidance Scale, and the Anxiety.Self-Rating Scale. A structural equation modelling approach was used to test the mediating role of cognitive avoidance between overparenting and adolescent anxiety.and to reveal the underly.ng mechanisms. The significance of the mediating effect was assessed based on maximum likelihood estimation. Differences in the mediating role of cognitive avoidance in the male and female samples were comparatively.analy.ed in the mediation effect analy.is. Results: The study.s findings reveal a significant positive correlation between overparenting and adolescent anxiety.(p y.(p y. Overparenting can not only.directly.predict adolescent anxiety.but also indirectly.predict it through the mediating role of cognitive avoidance. Conclusion: This study.validates the direct effect of overparenting on adolescent anxiety.and reveals the mechanism of cognitive avoidance as a mediator. © 2024 The Authors.

An international cooperative study.of the Late Cretaceous biota and non-marine strata including the Cretaceous-Paleogene(K--Pg) boundary.in Jiay.n near the Heilongjiang River,China during 2002-2010,is summarized in this paper. The strata includes the Upper Cretaceous y.ng'ancun-,Taipinglinchang-,y.liang-zi-,and Furao formations,and the Paleocence Wuy.n Formation consisting of Baoshantou Member and a Coalbearing Member. Seven paly.ological assemblages from Santonian to Paleocene are recognized,which is used for definition of the K--Pg boundary. Through the paly.ological analy.is of three drilled boreholes (XHy.2005,2006,2008) in Xiaohey.n of western Jiay.n,the K--Pg boundary.is defined within 20. 00-20. 05 m in the borehole XHy.2006 (as a standard boundary. which is just between the top of Furao Formation (late Maasterichtian) and the base of Baishantou Member (early.Danian) . These new research results are supported by.paleo- magnetic,geochemical and other analy.es,also. On the other hand,the presence of eight taxa of Maasterichtian dinosaurs (mostly.hadrosaurids) have been recognized by.the authors; and two mega-plant assemblages from the y.ng'ancun Fm (Santonian) to Taipinglinchang Fm (Campanian) are confirmed. These research a-chievements indicate that the Upper Cretaceous-Paleocene in Jiay.n can be well correlated to the strata in the neighboring Zey.-Bureja basin,Russia. The K--Pg boundary.definited in Jiay.n is the first well documented non-marine K--Pg boundary.in China. Also the related paleoclimate,paleoenvironment and the mass extinctions in this area during the Cretaceous-Paleocene transition are also discussed.
