Relations Among the Home Language and Literacy Environment and Children’s Language Abilities: A Study of Head Start Dual Language Learners and Their Mothers

Research Findings: This study explored the relations between Spanish–English dual language learner (DLL) children’s home language and literacy experiences and their expressive vocabulary and oral comprehension abilities in Spanish and in English. Data from Spanish–English mothers of 93 preschool-age Head Start children who resided in central Pennsylvania were analyzed. Children completed the Picture Vocabulary and Oral Comprehension subtests of the Batería III Woodcock–Muñoz and the Woodcock–Johnson III Tests of Achievement. Results revealed that the language spoken by mothers and children and the frequency of mother–child reading at home influenced children’s Spanish language abilities. In addition, the frequency with which children told a story was positively related to children’s performance on English oral language measures. Practice or Policy: The findings suggest that language and literacy experiences at home have a differential impact on DLLs’ language abilities in their 2 languages. Specific components of the home environment that benefit and support DLL children’s language abilities are discussed.     

‘Motivate’: the effect of a Football in the Community delivered weight loss programme on over 35-year old men and women’s cardiovascular risk factors

The purpose of this study was to examine whether an innovative, inclusive and integrated 12-week exercise, behaviour change and nutrition advice-based weight management programme could significantly improve the cardiovascular risk factors of overweight and obese men and women over the age of 35. One hundred and ninety-four men and 98 women (mean age?=?52.28?±?9.74 and 51.19?±?9.04) attending a community-based intervention delivered by Notts County Football in the Community over one year, took part in the study. Height (m), weight (kg), fitness (meters covered during a 6?min walk) and waist circumference (cm) were measured at weeks 1 and 12 as part of the intervention. Changes in body weight, waist circumference and fitness for men and women were measured by a 2-way repeated measures ANOVA, with significance set to p?<?0.05.Weight, waist circumference and fitness significantly improved over time in both men (4.96?kg, 6.29?cm, 70.22?m; p?<?0.05) and women (4.26?kg, 5.90?cm, 35.29?m; p?<?0.05). The results demonstrated that the FITC lead weight loss intervention was successful in significantly improving cardiovascular risk factors in both men and women. In particular, the weight loss reductions achieved were comparable to those seen in similar, more costly men-only programmes. This is the first study to demonstrate the efficacy of such an intervention in an inclusive, mixed gender programme and more specifically, in women.     

Hong Kong University and Polytechnic Grants Committee

The political uncertainties surrounding Hong Kong's future as a British Crown Colony have not inhibited either the Hong Kong Government or its particular version of a University Grants Committee (UGC) system from devising and planning a continuing expansion of higher education at a time when most other countries are levelling off or contracting their own.This article deals with the many unique features of the Hong Kong situation of which perhaps the most important is the nature of the Hong Kong Government - traditionally colonial and potentially authoritarian, not elected yet highly sensitive to Chinese opinion both internally and externally, and highly efficient in most of its management activities in spite of a strongly laisser faire tradition.The Hong Kong UGC system is charged with much wider planning functions throughout higher education than elsewhere and is responsible for the polytechnic as well as the two universities - hence its trans-binary designation as the University and Polytechnic Grants Committee. While this has helped its overall planning and academic guidance roles, it has involved it in severe difficulties in relation to its basic financial role which requires it to develop methodologies of financial assessment of Polytechnic costs for which no overseas models exist. Its academic membership is still entirely from overseas, with inevitable repercussions on its ability to arrange adequate collective discussion and its reliance on its local secretariat who act as the Government's de facto Department of Higher Education.

A Methylome‐Wide Association Study of Trajectories of Oppositional Defiant Behaviors and Biological Overlap With Attention Deficit Hyperactivity Disorder

In 671 mother–child (49% male) pairs from an epidemiological birth cohort, we investigated (a) prospective associations between DNA methylation (at birth) and trajectories (ages 7–13) of oppositional defiant disorder (ODD), and the ODD subdimensions of irritable and headstrong; (b) common biological pathways, indexed by DNA methylation, between ODD trajectories and attention deficit hyperactivity disorder (ADHD); (c) genetic influence on DNA methylation; and (d) prenatal risk exposure associations. Methylome‐wide significant associations were identified for the ODD and headstrong, but not for irritable. Overlap analysis indicated biological correlates between ODD, headstrong, and ADHD. DNA methylation in ODD and headstrong was (to a degree) genetically influenced. DNA methylation associated with prenatal risk exposures of maternal anxiety (headstrong) and cigarette smoking (ODD and headstrong).
