Dietary antioxidants and exercise

Muscular exercise promotes the production of radicals and other reactive oxygen species in the working muscle. Growing evidence indicates that reactive oxygen species are responsible for exercise-induced protein oxidation and contribute to muscle fatigue. To protect against exercise-induced oxidative injury, muscle cells contain complex endogenous cellular defence mechanisms (enzymatic and non-enzymatic antioxidants) to eliminate reactive oxygen species. Furthermore, exogenous dietary antioxidants interact with endogenous antioxidants to form a cooperative network of cellular antioxidants. Knowledge that exercise-induced oxidant formation can contribute to muscle fatigue has resulted in numerous investigations examining the effects of antioxidant supplementation on human exercise performance. To date, there is limited evidence that dietary supplementation with antioxidants will improve human performance. Furthermore, it is currently unclear whether regular vigorous exercise increases the need for dietary intake of antioxidants. Clearly, additional research that analyses the antioxidant requirements of individual athletes is needed.

The role of child temperament as a predictor of early literacy and numeracy skills in preschoolers

A study was performed to explore the role of temperament as a predictor of early literacy and numeracy skills in preschoolers. The participants in this study were 94 children (46 males, 48 females) enrolled in half-day junior kindergarten (M_age= 51.52,SD = 3.25 mos.). Parents completed theColorado Child Temperament Inventory (CCTI, Buss and Plomin 1984 and Plomin). Child interviews were conducted, and vocabulary, concepts about print, counting, and numeracy skills were assessed. Results from hierarchical regression analyses revealed that temperament contributed uniquely to the explanation of literacy and numeracy skills over and above well-established indicators of a child’s academic achievement (i.e., parental education, gender, vocabulary). Results are discussed in terms of educational and developmental implications.     

Parents’ Perceptions of Child Care for Children with Disabilities

Sixteen Minnesota families with children with disabilities participated in a 2-year interview study of their care experiences. Findings show that families developed a network of care providers, struggled to pay additional costs for care, were not informed of community services and programs, and believed that their children received adequate child care. This study highlights the need to provide information to families and providers and to link services in both rural and urban communities.

The mental and physical health difficulties of children held within a British immigration detention center: A pilot study

ObjectiveThe present study aimed to assess the mental and physical health of children held within a British immigration detention center.MethodA total of 24 detained children (aged 3 months to 17 years) were assessed with their parents or carer after being referred by a registered legal charity. Thirteen were seen by a pediatrician alone, 4 by a psychologist alone, and 7 by both professions using semi-structured clinical interviews. The psychologist also used standardized self-report questionnaires to measure psychopathology.ResultsDuring the psychological assessment of 11 children, 8 met criteria for psychiatric “caseness” on the Strengths and Difficulties Questionnaire. All 11 reported symptoms of depression and anxiety. Sleep problems, somatic complaints, poor appetite, emotional symptoms, and behavioral difficulties were common. Symptoms of global distress were also reported by all 9 parents. According to pediatric assessment 8 out of 20 children had lost weight. Six had missed health appointments and 2 were taken to hospital. Nutritional, developmental, educational, and child protection concerns were raised.ConclusionsDetained children were found to be experiencing mental and physical health difficulties of recent onset, which appeared to be related to the detention experience. These findings support previous Australian studies demonstrating that detention is not in the best interest of the child. It suggests that current UK policies regarding the detention of children for purposes of immigration control should be re-examined. Further research in the area is required.Practice implicationsAlthough high levels of mental and physical health problems, as well as child protection concerns were detected, detained families had very limited access to appropriate assessment, support or treatment. The traumatic experience of detention itself also has implications for the sizeable proportion of psychologically distressed children who are eventually released from detention and expected to successfully reintegrate into British society; while those children who are deported are returned with increased vulnerability to future stressors.     

Mentoring circles in higher education

Traditionally, mentoring in higher education institutions has either occurred informally or as a planned program where junior staff members are matched with experienced staff members in a formal one‐to‐one program. While such programs have reported benefits to participants, many miss out on the opportunity. Further, mentoring dyads do little to enhance a more collaborative atmosphere in higher education settings. Alternative mentoring methods do exist and can provide advantages to the traditional approach. Mentoring circles are an innovative example of these alternative methods. The mentoring activity and subsequent evaluation described in this paper sought to explore the perceived benefits of a group mentoring model for academic staff.     

Mental health and special educational needs: exploring a complex relationship

The relationship between mental health and special educational needs is both complex and misunderstood. In this article, Richard Rose, Professor of Special and Inclusive Education, Marie Howley, Senior Lecturer, Ann Fergusson, Senior Lecturer, and Johnson Jament, a PhD student, all from the Centre for Special Needs Education and Research directed by Richard Rose at the University of Northampton, discuss findings from a national research project which explored the perceptions of pupil mental health needs by staff working in residential special schools. Teachers and other professional colleagues often feel ill-prepared to address mental health difficulties experienced by their pupils. This is, at times, exacerbated by a wider confusion when atypical behaviours are attributed to a diagnosed learning difficulty rather than being recognised as symptomatic of a mental health problem. The article suggests a need for clarification of the relationship between complex special educational needs and mental health and for increases in training opportunities and the development of resources for teaching about and supporting mental health and emotional well-being.     

Examining Factors Related to Academic Success of Military-Connected Students at Community Colleges

The number of military-connected students enrolling in community colleges has increased dramatically in the past decade, and this trend is expected to continue. This research focused on examining factors that contribute to the academic success of community college students. Specifically, the purpose of this quantitative study was to identify the demographic characteristics; campus relationships; and financial, academic and personal experiences that are associated with grade point average (GPA) and intent to return for military-connected students at seven community colleges. Identifying as a Student of Color (any race or ethnicity other than White) and experience meeting professors’ academic expectations were negatively associated with cumulative GPA, and feeling academically prepared to enter the institution was significantly and positively associated with intent to return. The results provide further evidence of the relationships among demographic and academic experiences and academic success. The authors offer recommendations for serving military-connected students at community colleges.     

When tensions between ideology and practice become personal: Unpacking mentorship in early childhood teacher education

University-based teacher education programs are criticized for being too theoretical, disconnected from the everyday realities of schools. To bridge this gap, teacher education programs give students year-long field experiences under the joint tutelage of mentor teachers and university faculty. However, this assumes that mentor teachers will not only be exemplary teachers, but skilled mentors as well. This article explores the tensions between the theoretical and practical work of teaching within mentoring relationships, specifically in spaces where teacher agency is limited by political, social, and cultural factors. The sociocultural, language approaches in many teacher education programs are seen as idealistic when pushed up against skills-based language approaches, advocated in classrooms. Using qualitative methods, this project follows three mentor/mentee pairs as they negotiate their relationships in an urban area in the Southwest United States. While all three pre-service teachers strongly believed that learning was a social practice, constructed through child inquiry and play, they struggled to maintain their ideologies and beliefs during their field experience. Pre-service teachers held firmly to their beliefs about teaching and learning, but holding onto these beliefs were wrought with personal and philosophical tensions. Pre-service teachers found limited agency in their practice and little support in implementing their own practices. Most importantly, unequal power dynamics and communication issues were obstacles towards mutually beneficial mentorship. Thus, preservice programs must address the importance of developing and cultivating the mentor/mentee relationship—a relationship that is pivotal in the construction of preservice teachers’ identities and practices.
