Book Description
Research and empirical work have revealed the importance of psychological/mental skills, factors, and strategies in improving athletic performance, especially in racket sports. High levels of self-confidence, commitment, motivation as well as the ability to imagine, self-regulate, set and achieved goals, control emotion, stress, and anxiety facilitate the ability of the racket sport players to achieve peak performance. For example, players and coaches recognize that the mental or psychological factor should be considered and trained in the same way as the technical or physical components. The aim of this Research Topic is to bring together articles in which psychological techniques, factors, or strategies are discussed, used, or tested in order to improve the performance of racket sport players such as tennis, table tennis, badminton, or squash, and also in new activities such as racketlon, paddle or beach tennis. Topics of primary interest include, but are not limited to: • Mental training for racket sports; • The role of mental coach in racket sports; • Psychological strategies to improve the performance in racket sports; • Relationship between performance and psychological factors; • Applied performance enhancement by means of psychological technics; • Measures of psychological variables in racket sport players; • Training of psychological skills for performance improvement in racket sport.

Book Description
The Influence and Predictability of Socioeconomic Factors of the 2018 PARCC Middle School ELA Scores in New Jersey By: Dr. Charlene F. Jones This quantitative research, The Influence and Predictability of Socioeconomic Factors of the 2018 PARCC Middle School ELA Scores in New Jersey, examines the predictive power of socioeconomic, parental, and school district factors on student academic achievement. The combined influence of parent education with a bachelor’s degree or higher and free- and reduced-price lunch factors demonstrate the highest statistical significance for predictability in this study. All fundamental variables utilized support a greater discussion on how we, as parents and educators, can influence standardized test results and ensure local education policies and recommendations therein are research-based and implemented effectively in diverse communities. Particularly during this new era, post-pandemic, we seek successful strategies to combat learning loss, increase educational opportunities, and predict, where possible, assessment results—all in support of the future of public education.

Book Description
Drug use in the workplace, its effect on performance and safety, and the role of workplace drug testing has received much attention in the popular press. But what do we actually know about this troubling issue? With an extensive and readable overview of the literature, the committee presents what we do know by examining the major issues: The extent and severity of drug use on and off the job. The strengths and weaknesses of methods for detecting drug use through standard drug tests. The effect of drug use on behavior, including the results of both laboratory and field studies that have examined work-related behavior and worker productivity. The effectiveness of interventions to deal with drug use, such as employee assistance programs, health promotion programs, and treatment programs for substance abuse. This volume will be of practical interest to human resource and employee assistance program managers, policymakers, and investigators.

Book Description
Weighting of variables in a regression equation so as to maximize prediction of a criterion presents several problems. Optimal weighting in the sample case means that chance-related error is also weighted indiscriminately. Because such error will not relate to the criterion in subsequent samples, a sample multiple correlation (R) will be on the average larger than the population value (overfit), and its value on cross-validation will be lower than in the quation-development sample (shrinkage). The influence of characteristics of the population and other conditions of the sampling situation on the outcome and stability of the regression equation has not been well understood. In particular, the role played by the relationship of initial predictor set size (M) to sample size (N) has not received adequate attention. The report attempted to examine and isolate the role of sampling error in the magnitude and stability of sample multiple R values obtained by incremental test selection techniques. The effect of selected factors on the impact of sampling error was examined. Three proposed shrinkage estimation formulas were evaluated for effectiveness, and a search was conducted for more efficient formulas incorporating the M/N ratio. Method of controlling shrinkage and overfit were discussed and evaluated. (Author).

Book Description
The United States is among the wealthiest nations in the world, but it is far from the healthiest. Although life expectancy and survival rates in the United States have improved dramatically over the past century, Americans live shorter lives and experience more injuries and illnesses than people in other high-income countries. The U.S. health disadvantage cannot be attributed solely to the adverse health status of racial or ethnic minorities or poor people: even highly advantaged Americans are in worse health than their counterparts in other, "peer" countries. In light of the new and growing evidence about the U.S. health disadvantage, the National Institutes of Health asked the National Research Council (NRC) and the Institute of Medicine (IOM) to convene a panel of experts to study the issue. The Panel on Understanding Cross-National Health Differences Among High-Income Countries examined whether the U.S. health disadvantage exists across the life span, considered potential explanations, and assessed the larger implications of the findings. U.S. Health in International Perspective presents detailed evidence on the issue, explores the possible explanations for the shorter and less healthy lives of Americans than those of people in comparable countries, and recommends actions by both government and nongovernment agencies and organizations to address the U.S. health disadvantage.
