Heat production and storage are positively correlated with measures of body size/composition and heart rate drift during vigorous running

The purposes of this study were to determine the relationships between: (a) measures of body size/composition and heat production/storage, and (b) heat production/storage and heart rate (HR) drift during running at 95% of the velocity that elicited lactate threshold, which was determined for 20 healthy recreational male runners. Subsequently, changes in skin and tympanic temperatures associated with a vigorous 20-min run, HR, and VO2 data were recorded. It was found that heat production was significantly correlated with body mass (r = .687), lean mass (r = .749), and body surface area (BSA, r = .699). Heat storage was significantly correlated with body mass (r = .519), fat mass (r = .464), and BSA (r = .498). The percentage of produced heat stored was significantly correlated with body mass (r = .427), fat mass (r = .455), and BSA (r = .414). Regression analysis showed that the sum of body mass, percentage of body fat, BSA, lean mass, and fat mass accounted for 30% of the variability in heat storage. It was also found that HR drift was significantly correlated with heat storage (r = .383), percentage of produced heat stored (r = .433), and core temperature change (r = .450). It was concluded that heavier runners experienced greater heat production, heat storage, and core temperature increases than lighter runners during vigorous running.     

Effectiveness of the Student Success Course on Persistence,Retention, Academic Achievement,and Student Engagement

ABSTRACT

Despite a great increase in the numbers of students enrolling in higher education, specifically at community colleges, the successful completion rates for these students has remained static since the 1970s. When reviewing strategies to increase student retention and successful completion, the Student Success Course (SSC) has emerged as a promising and prominent strategy for community colleges. Given that, the purpose of this sequential mixed methods study was to determine if participation in a SSC influences persistence, retention, academic achievement, and student engagement on a community college campus. Data were collected from a purposeful sample of 197 SSC participants at a middle sized community college in southeast Texas and compared to a matched sample of 235 non-SSC participants. Twelve former SSC participants were also interviewed in an attempt to build a more empirical understanding of the impact of the SSC on student engagement and, thus, the students’ decisions to remain in college. Results of this study indicate that a relationship exists between participation in the SSC and persistence, retention, academic achievement in English and mathematics, and student engagement. Additionally, participants claim that taking the SSC not only altered their perceptions of the importance of the course, but their social and study skills as well.     

On Going (Way) Beyond One’s Data: A Proposal to Restrict Recommendations for Practice in Primary Educational Research Journals

To counteract what we see as a growing research-reporting concern, we propose the following editorial-policy change regarding the content of primary research articles in educational research journals: Contributors should restrict their discussion and conclusions to their data and not offer recommendations for educational practice nor speculate about the educational policy implications of their research. We believe that this change will be beneficial for maintaining a separation between evidence and opinion concerning the legitimate warrants of empirical research. We suggest viable accompaniments and alternatives to authors offering practical recommendations and policy speculations in primary-research journal articles. Among these is to rely on all sources of evidence, including systematic research syntheses based on the aggregated contribution of multiple research studies from different sources, with recommendations for practice tailored to specific situations so that both their validity and utility will be increased. It is hoped that our proposed policy change will initiate a conversation among researchers, editors, reviewers, and educational-policy experts with respect to the scope and purpose of primary research journal articles.     

He Asked Me What!?—Using Shared Online Accounts as Training Tools for Distance Learning Librarians

ABSTRACT

This study explores the idea of creating a knowledge base from shared online accounts to use in training librarians who perform distance reference services. Through a survey, follow-up interviews and a case study, the investigators explored current and potential use of shared online accounts as training tools. This study revealed that the participants viewed the concept positively, but many encountered barriers to effectively employing a local knowledge base as a training tool.     

Do Infants Use Their Own Images to Locate Objects Reflected in a Mirror?

The ability of infants to locate a toy from a mirror reflection was investigated in 3 experiments. In the first, it was found that a minority of 22-month-old infants turned to locate the toy that was the source of the reflection, and that localization of the toy occurred regardless of whether the infants' own image was visible in the mirror. The results of 2 further experiments indicated that younger infants aged 14 and 18 months rarely use mirror information to locate a toy. When they do so, they also turn whether or not images of themselves are visible. It is concluded that tasks involving the localization of objects or events from mirror images are not direct indices of self-recognition. Rather, they indicate the skill of infants in using the mirror as a perceptual tool.     

Participating in a Collaborative Action Learning Set (CAL): beginning the journey

Action learning is being increasingly utilised as a strategy to underpin practitioner focused development and research projects in healthcare generally and nursing in particular. Whilst facilitators of and participants in action learning have a variety of resource materials to guide their practice and participation, there continue to be few systematic and/or evaluative accounts of the experience of participating in action learning for potential action learning participants to draw upon. This paper attempts to address this agenda. The paper presents an interpretive evaluation of the experience of nurses participating in action learning as the learning strategy underpinning a 3-year emancipatory practice development/practitioner research programme. In particular, the paper focuses on the experience of ‘joining a learning set’. This focus has been adopted as the theory of action learning emphasises the principle of ‘voluntariness’, but yet action learning is increasingly being pre-prescribed as a component of development and research programmes. Such was the case with the programme reported on in this paper. The paper describes an approach used to evaluate learning that was adopted in this programme and in particular the initial evaluation stage that focuses on participants' feelings about joining an action learning set. The data collection and analysis processes are described and the key themes arising from the analysis (‘self-preservation’ versus ‘development of self’) discussed. It is concluded that working with principles of enlightenment is essential to successful action learning and the transformation of workplace cultures.
