In-House Training on New Library Processes at the NIST Research Library: A Case Study

This case study describes the development and implementation of a home-grown internal training program to teach the reference staff at a U.S. federal government library a new process for obtaining research materials that are not owned through alternative means rather than through the traditional interlibrary loan. Proficiency in the new process and increased use of existing resources were goals of the program. Included are the activities related to planning, logistics, success indicators, and lessons learned in the development and delivery of the in-house training program.     

Perceptions of Communication With Gay and Lesbian Family Members: Predictors of Relational Satisfaction and Implications for Outgroup Attitudes

This study investigates perceptions of family communication among members with different sexual identities. Specifically, from the perspective of heterosexual family members (N = 129), the study takes an intergroup perspective to determine how accommodative and non-accommodative communication and attitudes toward homosexuality predict intergroup anxiety and relational satisfaction with gay or lesbian family members. Further, the manner in which family communication influences attitudes toward homosexuality is examined. Results are discussed in terms of implications for research on heterosexual–homosexual interaction, family communication, and intergroup communication, in general.     

An analysis of Social StoriesTM research using an evidence‐based practice model

The number of Social Stories^TM studies and reviews has increased in recent years, yet concerns regarding quality and effect sizes continue to be expressed. With the emphasis on evidence‐based practices (EBPs) for the education and treatment of people with autism spectrum disorders (ASD), this issue becomes of paramount importance as professionals and parents attempt to select interventions for the people with ASD in their care. The current study makes a unique contribution in its use of an extensive EBP evaluation model to examine 33 single‐subject studies across 13 peer‐reviewed journals, a 12‐year period, and a wide range of grouping variables. Using the Mayton, Wheeler, Menendez and Zhang (2010) EBP evaluation protocol, studies were investigated in terms of eight quality indicators comprised 23 operationally defined standards. Studies included in this analysis met the following criteria: (1) they were intervention studies using single‐subject research designs; (2) they included only participants with disorders on the autism spectrum; and (3) the primary intervention was the use of a Social Story. Findings included on‐ or above‐standard acceptability in EBP indicators related to important aspects of dependent variables within studies and below‐standard acceptability in indicators related to both internal and external validity of studies.     

Emotion in online college classrooms: examining the influence of perceived teacher communication behaviour on students’ emotional experiences

This research focused on teacher communication behaviour as an influential factor in students’ educational experiences. This study examined students’ perceptions of emotion (involving teachers’ emotional support, students’ emotional work and students’ positive emotional valence toward class and teacher) as influenced by a variety of predicting variables: perceptions of teacher affinity-seeking as well as teachers’ positive behaviour alteration techniques, verbal immediacy and teacher online presence (involving the three factors of instructional design, organisation facilitating discourse and direct instruction). Relying on survey data collected from undergraduate and graduate students across disciplines enrolled in course offerings at a large public university, quantitative analysis examined relationships among existing factors previously studied in educational and communication research. Although this study uncovered multiple significant relationships between variables in the data set, students’ perceptions of their teachers’ verbal immediacy and presence in their instructional design were found to be most predictive relative to students’ emotions in online classrooms. Ultimately this project addresses and emphasises the need to more fully examine students’ emotions and related social experiences with virtual teachers and course content in higher education.     

Owning Your Emotions: Reactions to Expressions of Self- versus Other-Attributed Positive and Negative Emotions

This investigation tested the notion that speakers should own their emotions by using I-messages rather than You-messages when conveying their feelings. In Study 1, hypothetical self-attributed (I) emotion messages were compared to other-attributed (You) messages, with an I-You message added in Study 2. In both studies, the effect of both positive and negative emotion statements on perceived politeness, effectiveness, and emotional reactions were assessed. No differences were found in reactions to the message forms for negative emotions, but both studies provided evidence for differences in respondents' reaction to positive emotional expressions. These results suggest a self-serving bias; recipients do not distinguish between ways of phrasing negative emotions expressed to them, but apparently appreciate being given credit for speakers' positive emotions. Implications for therapists, communication consultants, and practitioners are discussed.     

Promotion of self-regulated learning in classrooms: investigating frequency, quality, and consequences for student performance

An implication of the current research on self-regulation is to implement the promotion of self-regulated learning in schools. Teachers can promote self-regulated learning either directly by teaching learning strategies or indirectly by arranging a learning environment that enables students to practise self-regulation. This study investigates teachers’ direct and indirect promotion of self-regulated learning and its relation to the development of students’ performance. Twenty German mathematics teachers with their overall 538 students (grade 9) were videotaped for a three-lesson unit on the Pythagorean Theorem. Students’ mathematics performance was tested several times before and after the observed lessons. A low-inferent coding system was applied to assess the teachers’ implicit or explicit instruction of cognitive strategies (e.g., organisation), metacognitive strategies (e.g., planning), and motivational strategies (e.g., resource management). High-inferent ratings were used to assess features of the learning environment that foster self-regulation. Results reveal that a great amount of strategy teaching takes place in an implicit way, whereas explicit strategy teaching and supportive learning environment are rare. The instruction of organisation strategies and some features of the learning environment (constructivism, transfer) relate positively to students’ performance development. In contrast to implicit strategy instruction, explicit strategy instruction was associated with a gain in performance. These results reveal a discrepancy between the usefulness of explicit strategy instruction and its rare occurrence in classrooms.     

Suburban legend: School cutoff dates and the timing of births

Many states require children to reach age 5 by a specified date in the calendar year in order to begin kindergarten. We use birth certificate records from 1999 to 2004 to assess whether parents systematically time childbirth before these eligibility cutoff dates to capture the option value of sending their child to school at a relatively young age, thereby avoiding a year of child care costs. Testing for discontinuities in the distribution of births around cutoff dates, we find no evidence that the option value influences the timing of birth. Similarly, we find no systematic discontinuities in average mothers’ characteristics or babies’ health outcomes around cutoff dates. Timing in the neighborhood of eligibility cutoffs occurs only when the cutoffs coincide with weekends or holidays, which may have implications for recent research that assumes birth dates in the neighborhood of cutoffs are essentially randomly assigned.     

Development of a measurement and feedback training tool for the arm strokes of high-performance luge athletes

Previous studies have shown that the start plays a critical role in sliding events and explains more than 55% of the variance of the final time in luge. Experts evaluate the contribution of the arm strokes to be 23% of the total starting performance. The aim of the present study was to develop a measurement and feedback training tool (Speedpaddler) for the arm strokes of high-performance luge athletes. The construction is an aluminium alloy framework with a customary belt conveyor system, which is driven by two synchronized servo motors. Training is possible with constant speeds up to 12 m · s(-1) or several speed curves, which simulate the acceleration of different luge tracks. The construction facilitates variations in the inclination and speed of the conveyor belts and thereby the resistance and movement speed. If the athlete accelerates the conveyor belts during arm-paddling, the torque of the motors decreases. Torque measurements and high-speed video offer valuable insights into the several technique criteria. Comparisons of arm-paddle cycle durations on ice and on the Speedpaddler with 18 luge athletes (national team and juniors) showed no statistical differences. The Speedpaddler might be a useful tool to improve starting performance all year round.
