The relationship between child behaviour problems at school entrance and teenage vocabulary acquisition: A comparison of two generations of British children born 30 years apart

Behaviour problems in early childhood have a lasting impact on cognitive development and education attainment in later adolescence and into adulthood. Here we address the relationship conduct and hyperactivity problems at school entrance, and vocabulary acquisition in adolescence. We compare performance in identical assessments across two generations of British children born 30 years apart in 1970 (n = 15,676) and 2000/2 (n = 16,628) and find that both conduct and hyperactivity problems have a negative association with later vocabulary in both generations. We take advantage of rich longitudinal birth cohort data and establish that these relationships hold once family socioeconomic status and a child’s personal characteristics and earlier vocabulary acquisition are taken into account. We also find that teenagers today achieved substantively lower scores in the vocabulary assessment compared to their counterparts born 30 years earlier, and that this holds across all categories within each of the family and individual characteristics considered in this article. As vocabulary and language skills are key prerequisites for wider learning, we discuss implications the findings have for education policies.     

THE ACHIEVEMENT GOALS ORIENTATION OF SOUTH AFRICAN FIRST YEAR UNIVERSITY PHYSICS STUDENTS

This paper is concerned with organizational principles of a pool of familiar problems of expert problem posers and the ways by which they are utilized for creating new problems. The presented case of Leo is part of a multiple-case study with expert problem posers for mathematics competitions. We present and inductively analyze the data collected in a reflective interview and in a clinical task-based interview with Leo. In the first interview, Leo was asked to share with us the stories behind some problems posed by him in the past. In the second interview, he was asked to pose a new competition problem in a thinking-aloud mode. We found that Leo’s pool of familiar problems is organized in classes according to certain nesting ideas. Furthermore, these nesting ideas serve him in posing problems that, ideally, are perceived by Leo as novel and surprising not only to potential solvers, but also to himself. Because of the lack of empirical research on experts in mathematical problem posing, the findings are discussed in light of research on experts in problem solving and on novices in mathematical problem posing.     

In the field with two rural primary school head teachers in England

ABSTRACT

The research focuses on the complexities associated with contemporary rural primary school leadership. The paper draws on in-depth ethnographic research undertaken in two contrasting English rural primary schools and their surrounding community over a period of three years and in particular the experiences and perspectives of the two head teachers from these schools. The paper is conceptually informed by the work of Bourdieu [1984. Distinction: A Social Critique of the Judgement of Taste. London: Routledge and Kegan Paul] and his work around field, habitus and capital as a means of understanding practice. The paper contends that as the neo-liberal economic field increasingly contaminates the field of schooling so a contextual understanding of the complex and shifting social space which a head teacher occupies, including their habitus and the capital they deploy, is of central importance to understanding practice.     

Supporting Transgender College Students: Implications for Clinical Intervention and Campus Prevention

This study examines the experiences of transgender college students in coping with stress in comparison to their cisgender peers. Undergraduate and graduate students from 73 colleges, totaling 26,292 participants, of which 47 identified as transgender completed an online survey. Transgender students reported greater exposure to trauma and higher rates of suicidal experiences, as well as different precipitants to reported stressful periods and sources of support than their cisgender peers. Implications for individual and group counseling as well as outreach and prevention to better support transgender students are explored.     

Mind the gap: Capturing value from basic research through combining mobile inventors and partnerships

To successfully generate more valuable technologies from accessing basic research knowledge, firms need to combine institutional and individual level bridges to universities and research institutes active in basic research. This combination is particularly important when the new technology builds on scientific prior art. While mobile inventors are needed to transfer and translate basic knowledge into new technologies, partnerships provide the commitment, resources and incentive structure to integrate this basic research knowledge more effectively into the firm’s innovation process, thus improving the value capture from mobile inventors. Our findings in the micro-electronics field illustrate the importance of jointly accounting for firm and inventor level industry-science links to assess their effectiveness and provides evidence on complementarity from using both. Furthermore, identifying the scientific nature of the technology projects critically determines whether the combination of these links allow to capture more value.     

The association between fundamental athletic movements and physical fitness in elite junior Australian footballers

This study investigated the associations between fundamental athletic movement and physical fitness in junior Australian football (AF). Forty-four under 18 players performed a fundamental athletic movement assessment consisting of an overhead squat, double lunge, single leg Romanian deadlift and a push up. Movements were scored on three assessment criterions using a three-point scale. Additionally, participants performed five physical fitness tests commonly used for talent identification in AF. A Spearman’s nonparametric correlation matrix was built, with correlation coefficients being visualised using a circularly rendered correlogram. Score on the overhead squat was moderately positively associated with dynamic vertical jump height on left (r_s = 0.40; P ≤ 0.05) and right (r_s = 0.30; P ≤ 0.05) leg take-off, stationary vertical jump (r_s = 0.32; P ≤ 0.05) and negatively associated with 20-m sprint time (r_s = ?0.35; P ≤ 0.05). Score on the double lunge (left/right side) was moderately positively associated with the same physical fitness tests as well as score on the multistage fitness test. Results suggest that improvements in physical fitness qualities may occur through concurrent increases in fundamental athletic movement skill, namely the overhead squat and double lunge movements. These findings may assist with the identification and development of talent.     

A Funny Thing Happened on the Way to the Checkpoint: Teaching Stand-Up Comedy in Occupied Palestine

ABSTRACT

This article considers ideas about the performance of personal stories in stand-up comedy that emerged during a teaching and performance project in a refugee camp in Palestine. After experimenting with a range of stand-up techniques and approaches, participants created public performances sharing their experiences of life under military occupation.     

An investigation of a novel three-dimensional activity monitor to predict free-living energy expenditure

Abstract

The aim of this study was to assess the capability of the 3dNX? accelerometer to predict energy expenditure in two separate, free-living cohorts. Twenty-three adolescents and 14 young adults took a single dose of doubly labelled water and wore a 3dNX? activity monitor during waking hours for a 10-day period while carrying out their normal routines. Multiple linear regression with backward elimination was used to establish the strength of the associations between various indices of energy expenditure, physical activity counts, and anthropometric variables. 3dNX? output accounted for 27% and 35% of the variance in the total energy expenditure of the adolescent and young adult cohort, respectively. The explained variance increased to 78%, with a standard error of estimate of 7%, when 3dNX? output was combined with body composition variables. The 3dNX? accelerometer can be used to predict free-living daily energy expenditure with a standard error of estimate of 1.65 MJ in adolescents and 1.52 MJ in young adults. The inclusion of anthropometric variables reduces the error to approximately 1 MJ. Although it remains to cross-validate these models in other populations, early indications suggest that the 3dNX? provides a useful method of predicting energy expenditure in free-living individuals.
