Authors:
Tova Michalsky

Front Psychol 2021 26;12:630197. Epub 2021 Mar 26.

School of Education, Bar-Ilan University, Ramat Gan, Israel.

Contemporary theories of learning and instruction as well as a large body of research have pinpointed the benefits of effective self-regulated learning (SRL) for students' academic achievements, yet research findings indicate that teachers' actual promotion of students' SRL strategies and students' actual use of such strategies are less common than expected. To extend the investigation of how and when teachers' expertise develops regarding SRL instruction practices in authentic classrooms, the current study compared preservice vs. inservice teachers' "noticing" of explicit SRL teaching behaviors in videotaped classroom vignettes.

Academic Achievement of Children in Same- and Different-Sex-Parented Families: A Population-Level Analysis of Linked Administrative Data From the Netherlands.

Demography 2021 Apr;58(2):393-418

School of Social Science, The University of Queensland, Brisbane, Australia.

Although numerous studies have examined how children raised in same-sex-parented families fare relative to children in different-sex-parented families, this body of work suffers from major methodological shortcomings. By leveraging linked administrative data from several population registers from the Netherlands covering the 2006-2018 period (n = 1,454,577), we overcome most methodological limitations affecting earlier research. The unique features of the data include complete population coverage, reliable identification of same-sex-parented families, a large number of children in same-sex-parented families (n = 3,006), multiple objective and verifiable educational outcomes, and detailed measures of family dynamics over children's entire life courses.

PeerJ Comput Sci 2021 23;7:e442. Epub 2021 Mar 23.

Department of Applied Informatics, Vytautas Magnus University, Kaunas, Lithuania.

Human posture detection allows the capture of the kinematic parameters of the human body, which is important for many applications, such as assisted living, healthcare, physical exercising and rehabilitation. This task can greatly benefit from recent development in deep learning and computer vision. In this paper, we propose a novel deep recurrent hierarchical network (DRHN) model based on that allows for greater flexibility by reducing or eliminating posture detection problems related to a limited visibility human torso in the frame, i.

Researching gender inequalities in academic labor during the COVID-19 pandemic: Avoiding common problems and asking different questions.

Gend Work Organ 2021 Mar 4. Epub 2021 Mar 4.

Department of Sociology University of Warwick Coventry UK.

As the COVID-19 pandemic unfolds, a growing body of international literature is analyzing the effects of the pandemic on academic labor and, specifically, on gender inequalities in academia. In that literature, much attention has been devoted to comparing the unequal impacts of COVID-19 on the research activities of women and men, with studies demonstrating that women's research productivity has been disproportionately disrupted, in ways that are likely to have detrimental effects in the short- and long-term. In this paper, I discuss that emerging literature on gender inequalities in pandemic academic productivity. Read More

Does Obesity Affect the Severity of Exercise-Induced Muscle Injury?

J Obes Metab Syndr 2021 Apr 5. Epub 2021 Apr 5.

Department of Sport Science, College of Life Science and Nano Technology, Hannam University, Daejeon, Korea.

This literature review investigates the effects of obesity on exercise-induced muscle injury and reexamines the potential mechanisms of exercise-induced muscle injury related to obesity. Several studies reported that high body mass index and percent body fat can significantly affect the markers of muscle injury after exercise, including maximal strength, delayed onset muscle soreness, creatinine kinase level, and myoglobin level. The potential mechanisms resulting in these outcomes include structural changes in the cell membrane induced by high fat levels, increased inflammatory responses due to adipose tissues, reduced muscle satellite cell activation and myogenesis due to lipid overload, differences in muscle fiber distributions, and sedentary behaviors.
