A Vendor Perspective: What Do All of These Changes Mean for Vendors?

Vendor keynote speaker Caitlin Trasande addressed the practical and applied implications of how government mandates and regulations drive innovations and research information management technologies, while tying in remarks made by Jane Marks, the publisher keynote speaker, and Scott Plutchak, the librarian keynote speaker. She is uniquely positioned to do this as she has been at Digital Science for 5 years, most recently as Head of Research Policy; holds a PhD in Neurobiology; and was very recently appointed Senior Strategy Editor at Nature. Trasande used products developed by Digital Science as examples to demonstrate how all sectors of the scholarly community are finding solutions to help enable compliance with mandates, such as those on data and Open Access. She also provided a futuristic look at how the UK government has begun to ask funded researchers to document the social impact of their research; how Digital Science worked with the UK government, and how likely this is to also happen in the United States.     

Influence of carbohydrate mouth rinsing on running and jumping performance during early morning soccer scrimmaging

Carbohydrate mouth rinse (CMR) is a novel method proposed to enhance endurance performance lasting ≤ 60 min. The current study examined the influence of CMR on anaerobic performance tasks in 11 collegiate female soccer players after an overnight fast. Athletes completed two experimental sessions, during which carbohydrate (CHO; 6% maltodextrin) or taste- and colour-matched placebo (PLA) mouth-rinse solutions were administered in a counterbalanced, double-blinded design. Three rounds of a 5-min scrimmage bout and series of performance tests including a single countermovement vertical jump (1VJ), a set of four consecutive vertical jumps, a 72-m shuttle run (SR72) and 18-m sprint comprised each trial. Thirst sensation (TS), session TS, ratings of perceived exertion (RPE) and session RPE were assessed as secondary outcomes. The first SR72 approached significance (p = 0.069), but no significant between-trials differences were observed for any of the mean performance tasks. The highest 1VJ scores did not differ for the first (CHO = 47.3 ± 3.4, PLA = 47.7 ± 3.5 cm; p = 0.43), second (CHO = 48.0 ± 4.1, PLA = 47.9 ± 3.5 cm; p = 0.82) or third bout (CHO = 47.4 ± 3.9, PLA = 48.1 ± 3.9 cm; p = 0.26). TS approached significance (p = 0.053) during the first bout. No significant differences (p > 0.05) were found for any of the perceptual variables. Current results fail to support ergogenic influence of CMR on anaerobic performance tasks in collegiate female athletes.     

The New National School Library Standards: Implications for Information Literacy Instruction in Higher Education

This paper explores the new American Association of School Libraries (AASL) National School Library Standards relative to the information literacy pipeline as K-12 students reach university-level learning environments. Shifts in the standards, and therefore eventual shifts in this pipeline, are examined. The new school library standards integrate standards for learners, school libraries, and school librarians. This paper will focus exclusively on the standards for learners, as this is where the primary crossover between high schools and academic libraries takes place. Potential implications and future directions for academic librarianship, especially relative to information literacy instruction, are discussed.     

Perceptions of Women and Men Leaders Following 360‐Degree Feedback Evaluations

In this study, researchers used a customized 360‐degree method to examine the frequency with which 1,546 men and 721 women leaders perceived themselves and were perceived by colleagues as using 10 relational and 10 task‐oriented leadership behaviors, as addressed in the Management‐Leadership Practices Inventory (MLPI). As hypothesized, men and women leaders, as well as their supervisors, employees, and peers, perceived women leaders to employ nine of the 10 relational leadership behaviors significantly more frequently than men leaders. Additionally, the employees' perceptions of their women leaders' use of task‐oriented behaviors were significantly higher when compared to similar assessments from the employees of men leaders. However, the leaders as well as their supervisors and peers perceived men and women leaders' use of task‐oriented behaviors as approximately equal. Broader implications of these findings are discussed.     

Blocking in autoshaped lever-pressing procedures with rats

Rats will approach and contact a lever whose insertion into the chamber signals response-independent food delivery. This “autoshaping” or “sign-tracking” phenomenon has recently attracted considerable attention as a platform for studying individual differences in impulsivity, drug sensitization, and other traits associated with vulnerability to drug addiction. Here, we examined two basic stimulus selection phenomena—blocking and overshadowing—in the autoshaped lever pressing of rats. Blocking and overshadowing were decidedly asymmetrical. Previously reinforced lever-extension conditioned stimuli (CSs) completely blocked conditioning to auditory cues (Exps. 1 and 2), and previously nonreinforced lever-extension CSs overshadowed conditioning to auditory cues. By contrast, conditioning to lever-extension CSs was not blocked by either auditory (Exp. 3) or lever-insertion (Exp. 4) cues, and was not overshadowed by auditory cues. Conditioning to a lever-insertion cue was somewhat overshadowed by the presence of another lever, especially in terms of food cup behavior displayed after lever withdrawal. We discuss several frameworks in which the apparent immunity of autoshaped lever pressing to blocking might be understood. Given evidence that different brain systems are engaged when different kinds of cues are paired with food delivery, it is worth considering the possibility that interactions among them in learning and performance may follow different rules. In particular, it is intriguing to speculate that the roles of simple cue–reinforcer contiguity, as well as of individual and aggregate reinforcer prediction errors, may differ across stimulus classes.     

Weight changes in children in foster care for 1 year

Objective

The aims of this study of predominately racial/ethnic minority children in foster care (N = 360, birth to 19 years old) in Los Angeles, CA were to examine the (1) prevalence of obesity (≥95 percentile) and overweight/obese (≥85 percentile) upon entrance to foster care (T1) and after 1 year in foster care (T2); (2) comparison of high weight categories to national statistics; (3) relationship of changes in weight status to age, reason for entry into foster care, and placement.

Methods

Chi-square test and McNemar test comparing paired proportions were used to determine whether there were significant changes in the proportion of high weight categories between T1 and T2. Chi-square test or Fisher's exact test were used to evaluate the association between age, placement, and reason for foster care with the change in weight category. Changes in weight were categorized as (1) decreased in weight, (2) remained at overweight or obese, (3) increased in weight, or (4) remained normal.

Results

The proportion of obese and obese/overweight children between ages 2 and 5 were significantly lower at T2 than T1. There were no significant changes in the prevalence of obesity for the total population at T2. Children age 6 or older had a higher prevalence of obesity and overweight/obesity compared to national statistics. Of children at all ages, 64.7% of children of all ages entered foster care with a normal weight and stayed in the normal range during their first year in foster care, 12.2% decreased their weight, 15.4% remained overweight or obese, and 7.7% increased their weight. Age and parental substance use was related to change in weight category from T1 to T2.

Conclusion

Children did not become more overweight or obese in foster care; however 28% of the children were obese or overweight upon entry into foster care. Children who are 6 years or older and obese upon entering foster care should be targeted for weight reduction. The pediatric community and child welfare system need to work together by including weight percentiles in the foster care file and training/monitoring child welfare caregivers in weight reduction interventions.     

Distracted Walking,Bicycling, and Driving: Systematic Review and Meta‐Analysis of Mobile Technology and Youth Crash Risk

This article examined the impact of mobile technology on young pedestrians, bicyclists, and drivers. A systematic search yielded 41 articles meeting inclusion criteria: peer‐reviewed, published before February 1, 2016, behavioral outcome related to pedestrian, bicycling, or driving in the presence of mobile technology use, youth sample. Eleven studies were meta‐analyzed to evaluate increased risk for crash/near‐crash while distracted. Risk of bias and quality of research were assessed. Across methodologies, developmental stages, and type of distracting task, mobile technology use impairs youth safety on the road. Quality of evidence was low (pedestrian) to moderate (driving). Findings are discussed from the perspective of cognitive and visual distractions. Policy and behavioral efforts should continue to reduce mobile technology use in transportation settings.
