Positive school climate and strong school identification as protective factors of adolescent mental health and learning engagement: A longitudinal investigation before and during COVID-19.

The COVID-19 pandemic resulted in significant disruptions for children and youth around the world, especially given school closures and shifts in teaching modes (on-line and hybrid). However, the impact of these disruptions remains unclear given data limitations such as a reliance on cross-sectional and/or short-interval surveys as well as a lack of broad indicators of key outcomes of interest. The current research employs a quasi-experimental design by using an Australian four-year longitudinal survey with student responses from Grade 7 to 10 (aged 12-15 years old) (N = 8,735 from 20 schools) in one education jurisdiction.

Hydrophobic, Ultrastable Cu for Robust CO Electroreduction to C Products at Ampere-Current Levels.

Copper (Cu) is the only known material that can efficiently electrocatalyze CO to value-added multicarbon products. Owing to the instability of the Cu state and microscopic structure in reactions, Cu catalysts are still facing big challenges with low selectivity and poor durability, particularly at high current densities. Herein, we report a rational one-step surface coordination approach for the synthesis of Cu dendrites with an ultrastable Cu state and hydrophobicity (Cu CF), even after exposure to air for over 6 months.

Silicon Cutting Waste Derived Silicon Nanosheets with Adjustable Native SiO Shell for Highly-Stable Lithiation/Delithiation.

Silicon is an excellent candidate for the next generation of ultra-high performance anode materials, with the rapid iteration of the lithium-ion battery industry. High-quality silicon sources are the cornerstone of the development of silicon anodes, and silicon cutting waste (SCW) is one of them while still faces the problems of poor performance and unclear structure-activity relationship. Herein, a simple, efficient, and inexpensive purification method is implemented to reduce impurities in SCW and expose the morphology of nanosheets therein.

Disciplinary differences in the study of the relationship between social variables and mental health: A systematic mapping review.

There has been sustained interest in the intersection between social constructs and mental health from diverse disciplines including psychiatry, sociology and public health. However, no systematic attempt has been made to catalogue what is meant by 'social' by different researchers, how variables deemed 'social' constructs are linked to mental health, nor whether these patterns differ by academic discipline. Understanding interdisciplinary differences and commonalities may reveal opportunities for interdisciplinary collaboration to enhance our understanding of how social factors relate to mental health.

What do we mean by "social" in mental health research?

This article presents a methodology designed to study what is considered "social" in research on the topic of mental health. Examining a sample of 289 academic publications, we coded the meanings attributed to "social" and their linkage to mental health. Reflecting on this methodology offers a way to discuss the various uses of the adjective "social," and highlights the significance of its (often lacking) definition in the construction of research objects.
