Behavioral and neurophysiological effects of morphological awareness training on spelling and reading

Behavioral and neurophysiological effects of a computer-aided morphological training protocol were examined in German-speaking children from Grades 3 to 9. Study 1 compared morphological awareness, reading, and spelling skills of 34 trained children with an untrained control group of 34 children matched for age, sex, and intelligence. All participants in the training group showed increases in morphological awareness, but only students from secondary school improved significantly in reading and spelling competences. In Study 2, a subsample of 8 trained children with poor spelling and reading abilities and 10 untrained children with higher language competencies underwent an electroencephalography testing involving three different language tasks. The training resulted in decreased theta-activity and increased activity in lower (7–10 Hz) and upper alpha (10–13 Hz). These findings reflect more effortful and attention-demanding processing after the training and suggest that children with poor spelling and reading abilities use the acquired morphological knowledge in terms of a compensatory strategy.     

Techniques and considerations for determining isoinertial upper‐body power

Power is an integral aspect of many sports. Although power output of the lower body is often measured during jumping and cycling movements, much less is known about power as pertains to the upper body musculature. Recently, isoinertial methods ‐ with constant gravitational load ‐ of power testing have become common, but little is known of the reliability and criterion validity of these tests as they pertain to sport performance. In addition, the varied methodology makes a lucid model more evasive. The aims of this review are to examine the various methods of assessing upper body power, to establish its role in predicting athletic performance, and to assess the body of literature that has assessed power output of the upper extremities by isoinertial methods. To our knowledge, only two studies on isoinertial upper‐body power have shown a direct correlation to sporting ability (Baker, 2001; Baker et al., 2001); therefore, many unanswered questions exist as to the efficacy of these tests as predictors of athletic ability or as a method to track athletes’ training over time. From this review we hope to allow the sport coach to assess the overall utility of these tests in terms of availability, safety and external validity.     

Project THREAD: Technology helping restructure educational access and delivery

This article describes Project THREAD (Technology Helping Restructure Educational Access and Delivery), an initiative funded by the U.S. Office of Education through its PT3 grant program. The project’s overarching goal is to prepare teachers to integrate modern technologies to fundamentally enhance teaching and learning in K-12 schools. Project initiatives include: (a) a series of in-service workshops for university faculty, administrators, field supervisors, and mentor teachers; (b) one-on-one follow-up support provided by project staff; (c) a minigrant program to support the development of technology-based learning activities for university courses; (d) expanded opportunities for students to apply technology in thier courses and field experiences; and (e) a redesign of selected courses that impact a large number of teacher candidates. The project’s evaluation is described, along with a discussion of outcomes and lessons learned. in recognition of the project’s scope and accomplishments thus far, the College of Education at the University of Nevada, Las Vegas (UNLV), was named the 2002 winner of the Best Practice Award for the Innovative Use of Technology by the American Association of Colleges for Teacher Education (AACTE).     

Role of emotion dysregulation in the relationship between childhood abuse and probable PTSD in a sample of substance abusers

This study examined associations among childhood abuse, emotion dysregulation, and probable posttraumatic stress disorder (PTSD) within a sample of 93 substance use disorder (SUD) patients in residential treatment. SUD patients with probable PTSD (vs. non-PTSD) reported (a) greater severity of childhood sexual, physical, and emotional abuse and (b) significantly higher levels of overall emotion dysregulation and the specific dimensions of difficulties engaging in goal-directed behavior when upset, difficulties controlling impulsive behaviors when distressed, limited access to effective emotion regulation strategies, and lack of emotional clarity. Additionally, significant positive associations were found between both childhood physical and emotional (but not sexual) abuse on the one hand and dimensions of emotion dysregulation on the other. Further analyses indicated that difficulties controlling impulsive behaviors when distressed accounted for the associations of both childhood physical and emotional abuse with probable PTSD status. Findings of the present study highlight a potential mechanism underlying the relationships between both childhood emotional and physical abuse and PTSD in SUD patients.     

A locus of control and social distance comparison of Canadian and West Indian-born students

Three hundred and seventy-nine participants were tested in the West Indies and in Canada, with the Rotter Locus of Control Scale and the Wolfgang Interpersonal Distance Test. The results indicated that West Indian adolescent students were more internally controlled than their Canadian counterparts. Also, overall, West Indian students showed more approach behavior toward significant interpersonal figures than Canadian students. In addition, no correlation was apparent between locus of control and social distance, suggesting that they are separate constructs. Implications of the findings for social adjustment of West Indian immigrants in Canada are discussed.     

Modular microfluidic system as a model of cystic fibrosis airways

A modular microfluidic airways model system that can simulate the changes in oxygen tension in different compartments of the cystic fibrosis (CF) airways was designed, developed, and tested. The fully reconfigurable system composed of modules with different functionalities: multichannel peristaltic pumps, bubble traps, gas exchange chip, and cell culture chambers. We have successfully applied this system for studying the antibiotic therapy of Pseudomonas aeruginosa, the bacteria mainly responsible for morbidity and mortality in cystic fibrosis, in different oxygen environments. Furthermore, we have mimicked the bacterial reinoculation of the aerobic compartments (lower respiratory tract) from the anaerobic compartments (cystic fibrosis sinuses) following an antibiotic treatment. This effect is hypothesised as the one on the main reasons for recurrent lung infections in cystic fibrosis patients.
