Benjamin Franklin and the glass Armonica

Benjamin Franklin was a man of remarkable versatility, especially well-known as a scientist, writer and politician. Less well-known are his activities as a musician. This article describes his invention of the glass Armonica, on which he played and for which he also composed music. In recent years there has been a revival of interest in instruments of this kind and an acoustical analysis has been made of the vibrating glasses in an attempt to explain their curiously haunting melody.     

Impressions of disadvantage: I — school versus university study orchestration and consequences for academic support

This study investigates the study orchestrations of engineering students who enter three universities from disadvantaged school backgrounds and are admitted to academic support programmes. The first part of this study examines the characteristics of the entry group as a whole and, on the basis of an analysis of the self-reported study orchestrations of the individuals involved, it is concluded that a significant subgroup of individuals enter university with manifestations of undesirable study behaviour that has serious consequences for academic support.The second part of this study examines the relationship between school study orchestration (as manifested on entry to university), subsequent study orchestration at two stages during the first year of study, and final outcome as evidenced in the end of year examination result. It is concluded that study orchestration is a relatively stable phenomenon for most individuals in the transition from school to university and that its early recognition can be a potential indicator of subsequent academic achievement depending on the nature of the assessment procedures employed in academic support programmes. The third part of this study investigates sources of variation in two subgroups of individuals whose study orchestrations change during the course of their first year. It is concluded that statistically significant, but different, sources of variation are associated with subgroups of individuals whose study orchestrations are either improving or deteriorating.The overall conclusions of this study are seen to be far reaching in terms of informing the selection procedures and the educational practice of academic support programmes as well as of undergraduate education in general.     

Teacher professional leadership in support of teacher professional development

Counteracting perceptions of teaching as a profession with a flat career trajectory may require professional leadership opportunities for experienced teachers that differ substantively from those typically available. This evaluation study investigated the results of a professional development initiative for subject specialist teachers seconded to a leadership role in their curriculum areas. Interview and survey data supported teacher growth in subject expertise and leadership capacity attributed to the opportunities provided by the new teacher-leadership role. The findings of this study indicate expanded leadership roles may further develop experienced professionals while simultaneously supporting teacher knowledge during a period of embedding educational reform.     

A critical reflection on the multiple roles required to facilitate mutual learning during service-learning in Creative Arts education

In this article, I critically reflect on my own learning during a community-based, service-learning pilot project, highlighting the multiple roles that were required of me as facilitator. I provided opportunity for student teachers in a Creative Arts module to engage with youth from a local township community. The purpose of the participatory action research was to explore how this process enhanced reciprocal learning. Data were generated through multiple qualitative methods in four cycles of interactive activities. Adapting to the challenges of community-based learning necessitated that I was flexible enough to know when to don the hat of educator or research designer and when to be less directive to promote professional development and intercultural competencies. I learned to value relational platforms, enable diverse modes of communication and find workable strategies for mutual learning. By sharing my lessons learned, I hope to provide a better understanding of the facilitator’s multiple leadership roles.     

SCHOOL PSYCHOLOGISTS AS MENTAL HEALTH PROVIDERS: THE IMPACT OF STAFFING RATIOS AND MEDICAID ON SERVICE PROVISIONS

As one out of five children in the United States demonstrate some type of mental or behavioral health concern warranting additional intervention, federal policies have emphasized the need for school‐based mental health (SBMH) services and an expansion of Medicaid reimbursement for eligible children and families. Most youth access mental health services at school; therefore, it is important to evaluate how staffing ratios, credentialing, and state Medicaid policies may influence school psychologists’ involvement in the delivery of SBMH services. A survey of 192 school psychologists found that as practitioner to student ratios increased, the availability and provision of SBMH services decreased. As state Medicaid policies have been found to influence the provision of mental health services at school, current study results demonstrate an association between state level Medicaid policies and the number of school psychologists qualified to bill for Medicaid‐reimbursable services. Implications for service delivery and policy development are discussed.     

Young Children’s Memories for Social Actions: Influences of Age,Theory of Mind,and Motor Complexity

Children learn actions performed by a social partner better when they misremember these actions as their own. Identifying the factors that alter the propensity to make appropriation errors is critical for optimizing social learning. In two experiments (N = 110), we investigate the developmental trajectory of appropriation errors and examine social-cognitive and motor-related factors in 3- to 8-year-olds. Children with better theory of mind (ToM) skills made fewer appropriation errors for motorically complex actions. Appropriation errors did not differ as a function of ToM if children could perform the corresponding actions. A second experiment replicated this effect and found no influence of collaborative context on appropriation errors. This research sheds light on the complex relations among development, social-cognition, and motor-related factors.     

The Public Values Failures of Climate Science in the US

This paper examines the broad social purpose of US climate science, which has benefitted from a public investment of more than $30 billion over the last 20 years. A public values analysis identifies five core public values that underpin the interagency program. Drawing from interviews, meeting observations, and document analysis, I examine the decision processes and institutional structures that lead to the implementation of climate science policy, and identify a variety of public values failures accommodated by this system. In contrast to other cases which find market values frameworks (the “profit as progress” assumption) at the root of public values failures, this case shows how “science values” (“knowledge as progress”) may serve as an inadequate or inappropriate basis for achieving broader public values. For both institutions and individual decision makers, the logic linking science to societal benefit is generally incomplete, incoherent, and tends to conflate intrinsic and instrumental values. I argue that to be successful with respect to its motivating public values, the US climate science enterprise must avoid the assumption that any advance in knowledge is inherently good, and offer a clearer account of the kinds of research and knowledge advance likely to generate desirable social outcomes.     

Responses of low and high compression during recovery after repeated sprint training in well-trained handball players

The aim of the study was to investigate the effects of wearing various levels of compression following repeated and exhausting sprint exercise on variables related to recovery. Twelve well-trained handball players performed three sessions of repeated and exhausting sprint exercise (30?×?30m). Directly after each session the participants wore tights extending from below the hip to the foot with either 0, 10, or 25?mm?Hg of compression onto the thigh and calf muscles. 48?h after the training session all participants performed 5?×?30m sprints and counter movement jumps. Before, directly after, 24?h, and 48?h after the training session venous blood samples were drawn for the determination of creatine kinase (CK), urea, C-reactive protein (CRP). At the same time points, subjective ratings of the Acute Recovery and Stress Scale (ARSS) questionnaires were obtained. The results for plasma concentrations of CK and urea showed ‘likely’ to ‘very, very likely’ beneficial effects for compression garments exerting 10?mm?Hg of compression (p?=?0.06–1.0). With regard to sprint and jump performance no differences were evident between 0, 10, and 25?mm?Hg (p?=?0.07–1.0). In addition, subjective scores from the ARSS did not differ between conditions over time (p?>?0.05). We conclude that the application of 10?mm?Hg leg compression compared to 0 and 25?mm?Hg of compression during 48?h of recovery from repeated and exhausting sprints lowered the plasma concentrations of CK and urea with no improvements in recovery for performance.     

Development of two short measures for recovery and stress in sport

The Acute Recovery and Stress Scale (ARSS) and the Short Recovery and Stress Scale were first established in German for the purposes of monitoring athletes’ current recovery-stress states in an economical and multidimensional manner. The aim of this paper is to document the development and initial validation of the English versions of these two psychometric monitoring tools. A total of 267 English-speaking athletes from a variety of team and individual sports participated in the study. The English versions demonstrated satisfactory internal consistency for both instruments (Cronbach α of .74–.89). Furthermore, good model fit was found for the eight scales of the ARSS, matching the structure and results of the German counterparts. Correlations among and between the scales reciprocate the theoretical constructs of stress and recovery, supporting the construct validity of the scales. Correlation coefficients within stress and recovery ranged between r_s?=?.29 and .68. The correlations between stress and recovery varied between r_s?=??.29 and ?.64. These constructs were further supported by correlations with the scores of the Recovery-Stress Questionnaire for Athletes, thereby showing convergent validity. The findings demonstrate initial validity and reliability of the two measures and reflect the results of the German versions. However, further research is needed before applying these scales in practical settings.
