A new jump-landing protocol identifies differences in healthy,coper, and unstable ankles in collegiate athletes

Ankle sprains are the most common injury in sport. With stability being an important risk factor for ankle sprains, a jump-landing protocol that can elicit differences in time-to-stabilisation (TTS) is necessary. The objective of this study was to develop a jump-landing protocol that could identify differences in TTS among healthy, ‘coper’, and unstable ankles of high-level athletes. 61 Division I collegiate athletes (32 females, 29 males; age: 19.9 ± 1.2 years; height: 176.6 ± 9.5 cm; mass: 74.3 ± 10.8 kg) participated in a jump-landing protocol that utilised sporting movements with preparatory steps and a vertical propulsion of the body in two multi-directional jumps. Utilising the landing on a force plate, ground reaction forces were used to quantify TTS. TTS of the unstable group (1.58 ± 0.62s) was significantly longer than the healthy (1.19 ± 0.37s; p = 0.050) and ‘coper’ (1.13 ± 0.49s; p = 0.019) groups in the forward hops. In addition, TTS of the lateral hops in the unstable group (1.55 ± 0.63s) was also significantly longer than the healthy (1.14 ± 0.37s; p = 0.026) and ‘coper’ (1.15 ± 0.39s; p = 0.028) groups. This new jump-landing protocol was able to elicit differences in TTS in high-level athletes that were not found using previous protocols. This new jump-landing protocol could be an effective tool to identify injury risk for high-level athletes.     

The Effect of Birth weight on Child Development Prior to School Entry

The present study examines variation in the effect of birth weight on children’s early cognitive and socioemotional outcomes by family socioeconomic status (SES). It is hypothesized that not only will lower birth weight children display worse cognitive and socioemotional outcomes prior to school entry, as prior research has found, but that effects will be stronger for lower-SES children. Using data from the Early Childhood Longitudinal Study–Birth Cohort, the study compares the age 4 outcomes of twins discordant for birth weight (N ~ 1,400). Twin fixed-effects models are run on the full twin sample and separately for low- and high-SES children. Results support the study’s hypotheses, suggesting that socioeconomic risk accentuates the effects of birth weight on early development.     

Classroom benefits of recess

Despite research demonstrating the importance of recess and free play for children, schools have been reducing free play time for more academic pursuits (Ramstetter et al. in J Sch Health 80:517–526, 2010; Waite-Stupiansky and Findlay in Educ Forum 66:16–25, 2001). Recently, there has been renewed interest in understanding the critical role that free play has for children’s development. The current study was designed to contribute to this literature as well as investigate how the type of environment in which children play influences their behaviour in the classroom. Children in grades 3–5 were tested before and after recess on cognitive measures of sustained attention and creativity. We found an increase in children’s sustained attention after recess. We additionally found that the type of environment in which children played differed depending on children’s behaviour and traits. Our findings suggest that recess is an important factor in children’s performance in school and should be considered an important part of the school day. Furthermore, we suggest that researchers should consider how individual differences influence the relationship between recess and children’s performance in the classroom. Implications of this research for schools are considered.     

Women teachers in Liberia: Social and institutional forces accounting for their underrepresentation

This study focuses on cultural and institutional factors that affect women's decision to become primary school teachers in Liberia. It exposes current dynamics that account for the male-dominated primary school teaching force and the barriers that dissuade women from becoming teachers. Based on semistructured interviews with pre-service and practicing teachers, school administrators, faculty at teacher training institutions, and Ministry of Education officials, the research findings indicate that women face several cultural barriers to receiving an education: patrilineal assumptions that daughters are destined to become resources for their husbands’ families (and thus a poor investment), early onset of sexual activity and teenage pregnancy, and social expectations about early family formation. Women who enter teacher training programs receive no recognition for their children and family responsibilities and are given insufficient financial support. When women do become teachers, they face difficult working conditions such as distant schools, poor housing facilities, late payments, and large classes filled with overage students. The probability of rural assignment brings additional dissuading factors: poor quality roads and few transportation options, a dearth of safe housing, and lack of childcare services. The study offers several policy options for increasing female teachers in the workforce.     

Improving High School–College Alignment: A Sociological Reform and New Challenges

This paper analyzes teacher responses to a distinctive reform that sought to ­implement alignment between high schools and colleges. A survey of 225 teachers is used to examine teachers’ perceptions of the reform’s effectiveness, further resources needed, and how perceptions changed over time. The reform was perceived as effective for college-bound students, but not for non-college-bound students, magnifying the discrepant needs of these groups. Steps to improve the program are suggested.     

Nonword repetition with spectrally reduced speech: some developmental and clinical findings from pediatric cochlear implantation

Nonword repetition skills were examined in 24 pediatric cochlear implant (CI) users and 18 normal-hearing (NH) adult listeners listening through a CI simulator. Two separate groups of NH adult listeners assigned accuracy ratings to the nonword responses of the pediatric CI users and the NH adult speakers. Overall, the nonword repetitions of children using CIs were rated as more accurate than the nonword repetitions of the adults. The nonword repetition accuracy ratings from both groups of subjects were correlated with open- and closed-set word recognition scores and forward digit spans. Only the perceptual accuracy scores from pediatric CI users were correlated with measures of speech production accuracy. These results suggest that although the pediatric CI users had more experience and success in perceiving speech under degraded auditory conditions, developmental differences in their memory skills prevent them from performing as well on working memory tasks as mature listeners.     

SSP-NASIG Joint Meeting: Wrap Up Panel with All Speakers

The expert speakers from the publishing, librarian, and vendor communities regrouped at the end of the Society for Scholarly Publishing–NASIG Joint Meeting to answer questions or elaborate on information they presented earlier during the meeting.     

Working around the ERM: Automating Accurate Electronic Serials Holdings Data in Bibliographic Records

Accurate holdings information for electronic serials is essential to librarians and users. Collection management staff spent copious amounts of time creating and updating links and public notes in electronic serials bibliographic records. This effort not only duplicated the work of our e-resource access and management software, but the updated information also quickly became outdated and inaccurate. This article describes our project to replace platform-specific Uniform Resource Locators (URLs) with an International Standard Serial Number–specific, static URL that points to the e-resource access and management software resource page and details the. process, from generating the URL and batch-editing machine-readable cataloging records, to garnering support from stakeholders and teaching users to navigate new steps.
