Avoiding the perils and fulfilling the promises of microfinance: A closer examination of the educational outcomes of clients’ children in Nicaragua

Many microfinance advocates claim that micro-credit has a positive effect on the educational outcomes of the children of micro-credit borrowers, and that these educational improvements provide us with evidence that micro-credit institutions are serving the social function for which they have been designed. This paper draws attention to this area of microfinance-impact research, and explores the promises and perils associated with the impact of microfinance on children's educational outcomes. The goal of this discussion is to ensure that the pervasive spread of microfinance to all parts of the globe is accompanied by benefits to children's educational outcomes. Drawing on the research we conducted in Nicaragua in 2008, we, the joint authors of this paper share insights that we hope can help to upgrade the practices currently being employed by both microfinancers and children's educational institutions, and to thereby strengthen academic-credit linkages within client households.     

Kinematic effects of a short-term fatigue protocol on punt-kicking performance

The punt kick is a fundamental skill used in several team sports; however, there has been a lack of research on how fatigue affects its technique. The purpose of this study was to determine the effects of short-term fatigue on punt-kicking performance. Eight elite and sub-elite Australian Football players performed maximal drop punt kicks on their preferred leg prior to, during and after a match-specific fatigue protocol. Optotrak Certus collected kinematic data from kick foot toe-off until ball contact. Repeated-measures analysis of variance showed a significant increase in 20 m sprint times after each short-term protocol, indicating fatigue. Foot speed did not significantly change with fatigue; however, increases in the range of motion at the pelvis and kicking thigh, along with increases in kicking thigh angular velocity, occurred. For the support leg, maximum knee flexion angular velocity increased while there was greater flexion found at the knee and hip, and greater range of motion at the knee. Players are able to make kinematic adaptations in order to maintain foot speed while punting for maximal distance after short-term efforts.     

Inconsistency of decision-making,the Achilles heel of referees

This study assessed whether decisions made by six qualified referees were consistent when watching the live 2016 televised Champions League Final. Referees were paired off into three separate rooms. Two referees watched the game with no supporters present. Two watched the game surrounded by Real Madrid supporters, and the remaining two watched the game surrounded by Athletic Madrid supporters. Referees were asked to decide whether each decision made by the on-field referee was either correct or incorrect. Results identified two types of refereeing inconsistency. The first type was a systematic tendency of the supporting crowds (both rooms) to influence the adjudicating referees to make fewer incorrect (disagree with the on-field referee) decisions (8 and 5) than referees in the “no supporters” room (19) (χ² = 11.22 [df = 2], P = 0.004). The second type of inconsistency was the home advantage “bias”, where the surrounding crowd influenced the adjudicating referees to favour their team, by disagreeing with the decision made by the on-field referee (χ² = 6.0 [df = 2], P = 0.0498). One explanation for these inconsistencies is that referees adopt a coping strategy of “avoidance”, i.e., when faced with difficult decisions, referees simply avoid making unpopular decisions by waving “play on”.     

An investigation of a novel three-dimensional activity monitor to predict free-living energy expenditure

The aim of this study was to assess the capability of the 3dNX accelerometer to predict energy expenditure in two separate, free-living cohorts. Twenty-three adolescents and 14 young adults took a single dose of doubly labelled water and wore a 3dNX activity monitor during waking hours for a 10-day period while carrying out their normal routines. Multiple linear regression with backward elimination was used to establish the strength of the associations between various indices of energy expenditure, physical activity counts, and anthropometric variables. 3dNX output accounted for 27% and 35% of the variance in the total energy expenditure of the adolescent and young adult cohort, respectively. The explained variance increased to 78%, with a standard error of estimate of 7%, when 3dNX output was combined with body composition variables. The 3dNX accelerometer can be used to predict free-living daily energy expenditure with a standard error of estimate of 1.65 MJ in adolescents and 1.52 MJ in young adults. The inclusion of anthropometric variables reduces the error to approximately 1 MJ. Although it remains to cross-validate these models in other populations, early indications suggest that the 3dNX provides a useful method of predicting energy expenditure in free-living individuals.     

Hitting the vault board: implications for vaulting take-off--a preliminary investigation

Gymnastics vaulting relies on a specialized take-off board for propulsion during the take-off phase of the vault. There is little information on the vault board and its behaviour. The aim of this study was to characterize the behaviour of the vault board during handspring drill take-offs of young male gymnasts (n = 36). The side of the top surface of the vault board and the wooden base were marked with three reflective markers, placed at the end of the vault board nearest the vault table and the centres of the two rearmost coil springs. The vault board surface was divided into two areas, rear and middle, based on marker location. The gymnasts' groups were determined from the location of the gymnast's lateral malleolus at vault board contact. Landings with the malleolus directly above or behind the rearmost marker were considered rear landings; landings with the malleolus forward of the rearmost marker were considered middle landings. Marker movements were automatically digitized and the right malleolus was hand digitized at 120 Hz. The maximum vertical displacement, vertical deflection time, and vertical velocity at take-off of the vault board markers did not differ statistically between board contact groups (all p > 0.05). The lateral malleolus velocity components also did not differ between board contact groups. Some low to moderately strong correlations were observed between the various marker displacements, durations and take-off velocities. Modest correlations were obtained between board markers and right malleolus velocities. The results indicate that foot contact on the vault board, as defined here, did not result in differences in board marker behaviour or right lateral malleolus velocities. This information does not support the idea that vault board contacts at the rear of the vault board are worse than contacts near the middle of the vault board. More research is needed to ascertain the role of the vault board's vibration characteristics to whole body actions that are observed in the subsequent preflight phase.

Up,close and personal: teachers' responses to an individualised professional learning opportunity

This paper provides an account of professional learning in action through documenting the experiences of three upper primary teachers as they engaged in reflection-on-action with the assistance of an academic mentor. Video-stimulated recall was used as a mechanism to encourage productive reflective practice, using video footage of each teacher's numeracy lessons. The results indicated that although it was a powerful medium for stimulating reflection, and the teachers indicated that it was a beneficial process, there was limited evidence to suggest that it resulted in substantial changes to their practices. Reasons for this are hypothesised and recommendations made for personalising professional learning to cater for the needs and context of individual teachers.     

CLASSROOM CONTEXTS AS THE FRAMEWORK FOR ASSESSING SOCIAL–EMOTIONAL ADJUSTMENT: A NATIONAL STUDY IN TRINIDAD AND TOBAGO

Contextually based assessments reveal the circumstances accompanying maladjustment (the when, where, and with whom) and supply clues to the motivations underpinning problem behaviors. The Adjustment Scales for Children and Adolescents (ASCA) is a teacher rating scale composed of indicators describing behavior in 24 classroom situational contexts. This study examines the Trinidad and Tobago national normative process for the ASCA contextual dimensions with a representative sample of elementary school children (N = 900). Exploratory and confirmatory factor analyses yielded the same three dimensions (peer context problems, teacher context problems, and learning context problems) observed in U.S. national samples. Dimensions were scaled using item response theory (IRT) and Bayesian scoring methods, with peer and learning context problems scores relating more strongly to clinical behavior disturbances and learning context problems showing stronger association with classroom learning styles. Implications for future research and practice are discussed.     

Evaluating clinical librarian services: a systematic review

Background: Previous systematic reviews have indicated limited evidence and poor quality evaluations of clinical librarian (CL) services. Rigorous evaluations should demonstrate the value of CL services, but guidance is needed before this can be achieved. Objectives: To undertake a systematic review which examines models of CL services, quality, methods and perspectives of clinical librarian service evaluations. Methods: Systematic review methodology and synthesis of evidence, undertaken collaboratively by a group of 8 librarians to develop research and critical appraisal skills. Results: There are four clear models of clinical library service provision. Clinical librarians are effective in saving health professionals time, providing relevant, useful information and high quality services. Clinical librarians have a positive effect on clinical decision making by contributing to better informed decisions, diagnosis and choice of drug or therapy. The quality of CL studies is improving, but more work is needed on reducing bias and providing evidence of specific impacts on patient care. The Critical Incident Technique as part of a mixed method approach appears to offer a useful approach to demonstrating impact. Conclusions: This systematic review provides practical guidance regarding the evaluation of CL services. It also provides updated evidence regarding the effectiveness and impact of CL services. The approach used was successful in developing research and critical appraisal skills in a group of librarians.     

Teachers' Mind,Brain, and Education Literacy: A Survey of Scientists' Views

While there is a growing interest among teachers to embed Mind, Brain, and Education (MBE) knowledge in their practice, most are still not clear about the key concepts in the field that have the potential to improve their pedagogical knowledge. The present study was conducted to identify the domains of current MBE knowledge that are important for teachers to know. Using a deductive qualitative survey design, data were collected by an online questionnaire from 112 experts of the global MBE community. Findings indicated that there are at least 18 conceptual areas of MBE literacy that need to be included in teacher professional development programs.
