Low energy availability in exercising men is associated with reduced leptin and insulin but not with changes in other metabolic hormones

Low energy availability, defined as low caloric intake relative to exercise energy expenditure, has been linked to endocrine alterations frequently observed in chronically energy-deficient exercising women. Our goal was to determine the endocrine effects of low energy availability in exercising men. Six exercising men (VO_2peak: 49.3 ± 2.4 ml · kg^?1 · min^?1) underwent two conditions of low energy availability (15 kcal · kg^?1 fat-free mass [FFM] · day^?1) and two energy-balanced conditions (40 kcal · kg^?1 FFM · day^?1) in randomised order. During one low energy availability and one balanced condition, participants exercised to expend 15 kcal · kg^?1 FFM · day^?1; no exercise was conducted during the other two conditions. Metabolic hormones were assessed before and after each 4-day period. Following both low energy availability conditions, leptin (?53% to ?56%) and insulin (?34% to ?38%) were reduced (P < 0.05). Reductions in leptin and insulin were independent of whether low energy availability was attained with or without exercise (P > 0.80). Low energy availability did not significantly impact ghrelin, triiodothyronine, testosterone and IGF-1 (all P > 0.05). The observed reductions in leptin and insulin were in the same magnitude as changes previously reported in sedentary women. Further research is needed to understand why other metabolic hormones are more robust against low energy availability in exercising men than those in sedentary and exercising women.     

Reading with vocabulary intervention: evaluation of an instruction for children with poor response to reading intervention

Interventions combining phonically based reading instruction with phonological training are generally effective for children with reading (decoding) difficulties. However, a minority of children respond poorly to such interventions. This study explored the characteristics of children who showed poor response to reading intervention and aimed to improve their literacy and language skills via a new theoretically motivated intervention. Twelve 8‐year‐old treatment poor responders with severe and persisting reading difficulties participated. A 9‐week reading intervention incorporating reading, phonological and vocabulary training was implemented. Before the intervention began the children showed almost no progress over 6 months of regular classroom education, on measures of oral language and literacy. Over the intervention period improvements were made on measures of reading, phonological awareness and language skills, which were maintained 6 months later. Although the intervention was effective, it should be noted that most children remained poor readers and require ongoing remediation.

Establishing the Initial Validity of the REDFLAGS Model: Implications for College Counselors

The aim of this study was to initially validate the REDFLAGS model, 8 cautionary warning signs of mental distress in college students. A test of internal consistency reliability and factor analysis supported the model's reliability and construct validity. Hierarchical logistic regression models endorsed the model's predictive validity; students’ recognition of the REDFLAGS model was significantly associated with increases in the odds of a peer‐to‐peer referral to the counseling center. Implications for college counselors are discussed.     

Higher education marketing – does inducing anxiety facilitate critical thinking or more consumerism?

Consumerism acts to maintain the emotional reversal of work and family. Exposed to a continual bombardment of advertisements through a daily average of three hours of television (half of all their leisure time), workers are persuaded to ‘need’ more things. To buy what they now need, they need money. To earn money, they work longer hours. Being away from home so many hours, they make up for their absence at home with gifts that cost money. They materialize love. And so the cycle continues [Baumann, Z. (2007). Collateral casualties of consumerism. Journal of Consumer Culture, 7, 1].     

Effects of an Animal-Assisted Intervention on Reading Skills and Attitudes in Second Grade Students

Reading skills are an important component of academic success for school-age youth, and are associated with increased academic performance and positive attitudes about school. The presence of an animal appears to reduce stress during reading. Therefore, the goal of this study was to assess the feasibility and effects of a 6-week after-school canine-assisted reading program in a public elementary school setting. Second-grade students were randomized to either an intervention group (n?=?14) in which they read to a registered therapy dog for 30 min once weekly for 6 weeks or a control group (n?=?14) with a standard classroom curriculum. Children’s reading skills were assessed biweekly and attitudes about reading were assessed pre- and post-intervention. The 6-week after-school canine-assisted reading program was feasible. Reading skill scores did not change significantly for either group. Although scores on recreational reading attitudes also did not change significantly for either group, the academic reading attitudes scores increased significantly in the intervention group (p?=?.002), but not in the control group (p?=?.06). These results support the benefits of an animal-assisted intervention for child literacy on children’s attitudes about reading and can inform future programs evaluating reading programs that include dogs.
