DDQ-mediated direct cross-dehydrogenative-coupling (CDC) between benzyl ethers and simple ketones.

Abstract: A direct Cross-Dehydrogenative-Coupling (CDC) between benzyl ethers and simple ketones was developed without using any metal catalyst. By using DDQ, various benzyl ethers and simples ketones were coupled together directly to form β-alkoxyl ketones efficiently. A mechanism in which the DDQ serves the double roles of an oxidizing agent and an organomediator was proposed.

Loneliness, isolation, and social support factors in post-COVID-19 mental health.

Abstract: Social support plays a key role in well-being, yet one of the major preventative efforts for reducing the spread of COVID-19 involves social distancing. During times of crisis, social support is emphasized as a coping mechanism. This requires many people to change their typical ways of connectedness and assumes that people have existing healthy relationships or access to technology. The purpose of this article was to explore the potential impact of COVID-19 on loneliness and well-being. Social support is an important consideration for understanding the impact of COVID-19 Psychological First Aid and Skills for Psychological Recovery, which are tools used to inform response methods to help people connect during isolation and are interventions that could be adapted to COVID-specific needs for what may be a prolonged isolation and postisolation. Given the many unknowns of COVID-19, studies are needed to understand the larger behavioral health impact to ensure resources are available, current, and evidence informed. Future studies are also needed to understand how access to technology may help buffer loneliness and isolation and thus improve the social outcomes of the current pandemic.

Sliding mode observers. Tutorial

Abstract: Discusses the problem of designing observers for state estimation using sliding modes. The theory and design principles are presented for linear and nonlinear systems. For linear systems the observers are developed using a block-observable form which is similar to a lower triangular matrix form. Compared with known approaches such observers have better robustness properties. In the case of nonlinear systems an equivalent control concept makes it possible to develop finite-time observers for a wide class of systems.

Discrimination, historical loss and enculturation: culturally specific risk and resiliency factors for alcohol abuse among American Indians.

Abstract: Objective: This report investigates the effects of discrimination, historical loss and enculturation on meeting diagnostic criteria for 12-month alcohol abuse among American Indians who share a common culture in the upper Midwest. We introduce an empirical measure of historical loss and hypothesize that historical loss will mediate the effects of discrimination on meeting 12-month diagnostic criteria for alcohol abuse. We also hypothesize that enculturation will be negatively associated with 12-month alcohol abuse and mediate or moderate the effects of discrimination. Method: A sample of 452 (351 women) American-Indian parents/caretakers (mean age: women = 39 years, men = 42 years) of children ages 10 to 12 years participated in diagnostic interviews for lifetime and 12-month alcohol abuse. The subjects' perceptions of discrimination, historical loss and enculturation were also measured. Structural equation modeling was used to evaluate direct and potential mediating effects of latent constructs of encult...
