Perspectives on Pandemics (1918-2020): What Does History Teach Us?

Since 1918, the world has experienced three additional pandemics, 1957, 1968, and 2009 - each less severe than the 1918 pandemic but raising the question of whether a high severity pandemic on the scale of 1918 could occur in modern times. Many experts have thought so and have recommended global preparation for possible pandemics as current preparedness is seen to warrant improvement. Clearly, hindsight suggests that we were insufficiently prepared in 2020 and much attention has been given to this situation.

The influence of self-compassion on emotional well-being among early and older adolescent males and females.

Self-compassion has been associated with well-being in adult samples, but has rarely been assessed in adolescents. In this study, 90 students ages 11-18 completed an online survey assessing self-compassion, life satisfaction, perceived stress and positive and negative affect. Findings indicated that older female adolescents had lower self-compassion than either older male adolescents or early adolescents of either gender, and self-compassion was associated significantly with all dimensions of emotional well-being with the exception of positive affect.

Mindfulness and Self-Compassion: Exploring Pathways to Adolescent Emotional Well-Being.

Adolescents today are confronted with the compounded stressors of life in our high-pressured society and the cognitive, physiological, and emotional changes characteristic of this stage of development. To explore ways to promote well-being in this population, mindfulness, defined as paying attention in the moment in an intentional and purposeful way, was examined in terms of its associations with aspects of emotional well being. It has been reported to have positive effects on emotional well-being in adults, and shows promise for similar results in research with youth.

Latent information in fluency lists predicts functional decline in persons at risk for Alzheimer disease.

Objective: We constructed random forest classifiers employing either the traditional method of scoring semantic fluency word lists or new methods. These classifiers were then compared in terms of their ability to diagnose Alzheimer disease (AD) or to prognosticate among individuals along the continuum from cognitively normal (CN) through mild cognitive impairment (MCI) to AD.

Method: Semantic fluency lists from 44 cognitively normal elderly individuals, 80 MCI patients, and 41 AD patients were transcribed into electronic text files and scored by four methods: traditional raw scores, clustering and switching scores, "generalized" versions of clustering and switching, and a method based on independent components analysis (ICA).

Lexical factors and cerebral regions influencing verbal fluency performance in MCI.

Objective: To evaluate assumptions regarding semantic (noun), verb, and letter fluency in mild cognitive impairment (MCI) and Alzheimer disease (AD) using novel techniques for measuring word similarity in fluency lists and a region of interest (ROI) analysis of gray matter correlates.

Method: Fifty-eight individuals with normal cognition (NC, n=25), MCI (n=23), or AD (n=10) underwent neuropsychological tests, including 10 verbal fluency tasks (three letter tasks [F, A, S], six noun categories [animals, water creatures, fruits and vegetables, tools, vehicles, boats], and verbs). All pairs of words generated by each participant on each task were compared in terms of semantic (meaning), orthographic (spelling), and phonemic (pronunciation) similarity.
