This study aims to test the effects of Celliant armbands on grip strength in subjects with chronic wrist and elbow pain. Celliant® is a functional textile fabric containing minerals that emit infrared radiation (IR) in response to body heat. IR-emitting fabrics have biological effects including the reduction of pain and inflammation and the stimulation of muscle function.

A randomized placebo-controlled trial recruited 80 subjects (40 per group) with a six-month history of chronic wrist or elbow pain (carpal tunnel syndrome, epicondylitis or arthritis) to wear an armband (real Celliant or placebo fabric) on the affected wrist or elbow for two weeks. Grip strength was measured by a dynamometer before and after the two-week study.

For the placebo group, the mean grip strength increased from 47.95 ± 25.14 (baseline) to 51.69 ± 27.35 (final), whereas for the Celliant group, it increased from 46.3 ± 22.02 to 54.1 ± 25.97. The mean per cent increase over the two weeks was +7.8% for placebo and +16.8% for Celliant (p = 0.0372). No adverse effects was observed.

Limitations include the wide variation in grip strength in the participants at baseline measurement, which meant that only the percentage increase between baseline and final measurements showed a significant difference. Moreover, no subjective measurements of pain or objective neurophysiology testes was done.

Celliant armbands are easy to wear and have not been shown to produce any adverse effects. Therefore, there appears to be no barrier to prevent widespread uptake.

IR-emitting textiles have been studied for their beneficial effects, both in patients diagnosed with various disorders and also in healthy volunteers for health and wellness purposes. Although there are many types of textile technology that might be used to produce IR-emitting fabrics, including coating of the fabric with a printed layer of ceramic material, incorporating discs of mineral into the garment, the authors feel that incorporating ceramic particles into the polymer fibers from which the fabric is woven is likely to be the most efficient way of achieving the goal.

Celliant armbands appear to be effective in painful upper limb inflammatory disorders, and further studies are warranted. The mechanism of action is not completely understood, but the hypothesis that the emitted IR radiation is absorbed by nanostructured intracellular water provides some theoretical justification.

We examine how authorities' use of fair decision-making procedures and power benevolently shape workers' impressions of them as competent and warm, which serve as a mechanism whereby authorities' behaviors shape workers' emotional responses. We investigate how the role of these impressions differs depending on authority gender and consider whether emotional responses differ for male and female subordinates.

We conducted a between-subjects experimental vignette study in which we manipulate an authority's behaviors and gender. We use multigroup mediation analysis to test our predictions.

Authorities who employ procedural justice and benevolent power elicit reports of heightened positive emotion experiences and intended displays and reports of reduced negative emotion experiences and intended displays. These behaviors also enhance views of authorities as competent and warm. The mediating role of impressions differs by authority gender. Authority behaviors prompt reports of positive emotions through conveying impressions that align with authorities' gender stereotypes (competence for men, warmth for women). In contrast, warmth impressions mediate effects of behaviors on reported negative emotions when authorities are men, whereas when authorities are women, benevolent power use directly reduces reported negative experience, and procedural justice reduces negative display. Female respondents are more likely to report positive emotion experience and display toward male authorities and negative display toward female authorities.

By examining competence and warmth impressions as mechanisms, we gain insight into how the process by which authority behaviors affect worker emotions is gendered and shed light on micro-level dynamics contributing to gender inequality at work.

Reference librarians in various library settings are often assigned responsibilities for training students, support staff, or other new professionals, a task for which they rarely have sufficient professional education. This bibliography recommends readings on topics that will assist reference librarians in understanding the philosophy of staff development. The readings listed here cover subjects such as: establishing an atmosphere that facilitates learning, assessing training needs, describing competent performance, writing clear and specific objectives, selecting appropriate training methods, maintaining skills and providing feedback, and evaluating the effectiveness of a training program.

This chapter describes five disciplinary domains of research or lenses that contribute to the design of a team tutor. We focus on four significant challenges in developing Intelligent Team Tutoring Systems (ITTSs), and explore how the five lenses can offer guidance for these challenges. The four challenges arise in the design of team member interactions, performance metrics and skill development, feedback, and tutor authoring. The five lenses or research domains that we apply to these four challenges are Tutor Engineering, Learning Sciences, Science of Teams, Data Analyst, and Human–Computer Interaction. This matrix of applications from each perspective offers a framework to guide designers in creating ITTSs.

Views about the nature and purpose of evaluation have developed quite dramatically over the last two decades. Unfortunately many peoples' expectations about what evaluation should be doing have not kept pace with these developments. In addition there has been a large amount of work carried out on the evaluation of general educational and social programmes, and much of this is both parallel to, and complimentary to, the evaluation of management training. This paper reviews recent trends in both fields using ideas from educational evaluation to clarify some of the problems encountered repeatedly in training evaluation and to suggest what might be more realistic expectations of evaluative activities.
