Season-long increases in perceived muscle soreness in professional rugby league players: role of player position,match characteristics and playing surface

Rugby League (RL) is a high-impact collision sport characterised by repeated sprints and numerous high-speed impacts and consequently players often report immediate and prolonged muscle soreness in the days after a match. We examined muscle soreness after matches during a full season to understand the extent to which match characteristics influence soreness. Thirty-one elite Super League players provided daily measures of muscle soreness after each of the 26 competitive fixtures of the 2012 season. Playing position, phase of the season, playing surface and match characteristics were recorded from each match. Muscle soreness peaked at day 1 and was still apparent at day 4 post-game with no attenuation in the magnitude of muscle soreness over the course of the season. Neither playing position, phase of season or playing surface had any effects on the extent of muscle soreness. Playing time and total number of collisions were significantly correlated with higher ratings of muscle soreness, especially in the forwards. These data indicate the absence “contact adaptations” in elite rugby players with soreness present throughout the entire season. Strategies must now be implemented to deal with the physical and psychological consequences of prolonged feeling of pain.     

Constructing Rotating Item Pools for Constrained Adaptive Testing

Preventing items in adaptive testing from being over- or underexposed is one of the main problems in computerized adaptive testing. Though the problem of overexposed items can be solved using a probabilistic item-exposure control method, such methods are unable to deal with the problem of underexposed items. Using a system of rotating item pools, on the other hand, is a method that potentially solves both problems. In this method, a master pool is divided into (possibly overlapping) smaller item pools, which are required to have similar distributions of content and statistical attributes. These pools are rotated among the testing sites to realize desirable exposure rates for the items. A test assembly model, motivated by Gulliksen's matched random subtests method, was explored to help solve the problem of dividing a master pool into a set of smaller pools. Different methods to solve the model are proposed. An item pool from the Law School Admission Test was used to evaluate the performances of computerized adaptive tests from systems of rotating item pools constructed using these methods.     

The role of intentionality and iconicity in children's developing comprehension and production of cartographic symbols

The contribution of intentionality understanding to symbolic development was examined. Actors added colored dots to a map, displaying either symbolic or aesthetic intentions. In Study 1, most children (5–6 years) understood actors' intentions, but when asked which graphic would help find hidden objects, most selected the incorrect (aesthetic) one whose dot color matched referent color. On a similar task in Study 2, 5- and 6-year-olds systematically picked incorrectly, 9- and 10-year-olds picked correctly, and 7- and 8-year-olds showed mixed performance. When referent color matched neither symbolic nor aesthetic dot colors, children performed better overall, but only the oldest children universally selected the correct graphic and justified choices with intentionality. Results bear on theory of mind, symbolic understanding, and map understanding.     

New fathers' postbirth views of antenatal classes: satisfaction, benefits, and knowledge of family services

New fathers (men whose partners had recently given birth) were asked to indicate to what degree antenatal classes had prepared them for childbirth, for their role as support persons, and for lifestyle and relationship changes after the birth. These postbirth findings were compared with a previous exit survey of male attendants at antenatal classes in which fathers-to-be predicted that the antenatal classes had prepared them well on all fronts. The new fathers in this study, however, reported that the antenatal classes had prepared them for childbirth but not for lifestyle and relationship changes after the birth. Additionally, couples who attended antenatal classes were asked to what extent they were familiar with family-related services in the region and how often they had used these services since the birth of their baby. Fathers were less familiar than mothers with the family-related services.     

Organizational Identification: A Mixed Methods Study Exploring Students’ Relationship with Their University

Organizational identification (OID) is the outcome of social construction processes in which individuals define themselves in terms of their organizational membership. Students’ identification with their university reflects value congruence with the institution and is reflected in communication. Drawing on social identity theory (SIT) and utilizing quantitative and qualitative data from students (n = 555), we found relationships between OID and construed external image of the university, trust in the university, satisfaction with the university, perceived interorganizational competition, and outcomes, including intended future involvement. Students were re-surveyed nine months later (n = 397, with 83 respondents matching Time 1 and Time 2) to assess their OID stability. Open-ended responses describe situations and events that strengthen/lessen OID. We offer implications for OID, SIT, and for organizational communication research and practice.     

An Experimental Study of Scheduling and Duration of "Tier 2" First-Grade Reading Intervention

This study compared the effects on reading outcomes of delivering supplemental, small-group intervention to first-grade students at risk for reading difficulties randomly assigned to one of three different treatment schedules: extended (4 sessions per week, 16 weeks; n = 66), concentrated (4 sessions per week, 8 weeks; n = 64), or distributed (2 sessions per week, 16 weeks; n = 62) schedules. All at-risk readers, identified through screening followed by 8 weeks of oral reading fluency (ORF) progress monitoring, received the same Tier 2 reading intervention in groups of 2 to 4 beginning in January of Grade 1. Group means were higher in word reading and ORF at the final time point relative to pretest; however, the groups did not differ significantly on any reading outcome or on rates of adequate intervention response. Of potential covariates, site, age, free lunch status, program coverage rate, and tutor were significantly related to student outcomes; however, the addition of these variables in multivariate models did not substantially change results. Rates of adequate intervention response were lower than have been reported for some first-grade interventions of longer duration.     

Nature is a nice place to save but I wouldn’t want to live there: environmental education and the ecotourist gaze

This article explores the role of ecotourism in the neoliberalisation of environmental education. The practice of ecotourism is informed by a particular ‘ecotourist gaze’ in terms of which the ‘education’ that providers characteristically offer is implicitly framed, embodying a culturally specific perspective in which western society is depicted as alienating and constraining and immersion in ‘wilderness’ is understood as a therapeutic escape from the reputed ills of industrial civilisation. While in the past, these educational aspects of ecotourism delivery have often contradicted the activity’s promotion as a quintessential neoliberal conservation mechanism, increasingly this education has become neoliberalised as well in its growing emphasis on the environment’s role as an instrumental provider of ‘ecosystem services’ for human benefit. In conclusion, this analysis calls for transcendence of these limitations in pursuit of a more inclusive environmental education encompassing diverse ethnic and socioeconomic dimensions of the human community.     

Considering the Museum Experience of Children with Autism

This article reports on a study that was designed to provide insight about the barriers that limit families with children with autism spectrum disorder (ASD) from visiting fine arts museums. Parents (N=54), and staff and volunteers (N=62) at the museum completed a questionnaire about their perceptions of the participation of children with ASD in museum activities. Some significant differences in responses were found between parents and museum staff and volunteers. Parents reported being thankful for the sense of community that Autism Awareness Family Celebrations provide, but were frustrated with reactions from others during typical museum experiences. Museum staff and volunteers expressed that museum participation was important, but responses were split between those who desired to learn more about ASD in order to create an optimal museum experience, and those who preferred not to take on this initiative. Studies such as this help museums become more inclusive.     

Early Responsiveness to Intensive Behavioural Intervention Predicts Outcomes Among Preschool Children with Autism

Archival data from a private day‐school offering early intensive behavioural intervention based on the principles of applied behaviour analysis to preschoolers with autism (N = 29) were analysed longitudinally. Teacher reports on the Assessment of Basic Language and Learning Skills (ABLLS) were available up to 4 times and on the Vineland Adaptive Behavior Scales—Classroom Edition (VABS‐CE), at 2 time points. Parent reports on the Autism Treatment Evaluation Checklist (ATEC) were available at 2 time points. All assessments occurred approximately at 6‐month intervals. Children showed statistically significant progress across all skill domains on the ABLLS and on selected subscales and the composite scales of the VABS‐CE and ATEC. Gains were substantial for some children and minor for others. When divided into performance‐based groups, both higher‐performing and lower‐performing groups showed improvement over time, with greater improvement for the higher‐performing group. Nine of 16 children who had been discharged from the programme entered inclusive kindergarten or first‐grade classrooms with an aide. Seven discharged children entered special education classrooms. No child progressed to the point that special education services were not needed. Findings are discussed relevant to the extant literature on early intensive behavioural intervention outcomes among young children with autism.     

A Commentary on Bowers (2020) and the Role of Phonics Instruction in Reading

Bowers (Educational Psychology Review, 32, 681-705, 2020) reviewed 12 meta-analytic syntheses addressing the effects of phonics instruction, concluding that the evidence is weak to nonexistent in supporting the superiority of systematic phonics to alternative reading methods. We identify five issues that limit Bowers’ conclusions: (1) definition issues; (2) what is the right question?; (3) the assumption of “phonics first”; and (4) simplification of issues around systematic versus explicit phonics. We then go on to consider (5) empirical issues in the data from meta-analyses, where Bowers misconstrues the positive effects of explicit phonics instruction. We conclude that there is consistent evidence in support of explicitly teaching phonics as part of a comprehensive approach to reading instruction that should be differentiated to individual learner needs. The appropriate question to ask of a twenty-first century science of teaching is not the superiority of phonics versus alternative reading methods, including whole language and balanced literacy, but how best to combine different components of evidence-based reading instruction into an integrated and customized approach that addresses the learning needs of each child.
