Applying the PEN-3 Cultural Model to Address HIV/AIDS Prevention in Rural Guatemala

Guatemala has an accelerating HIV rate, where prevalence is three times higher among indigenous than nonindigenous, comprising 21% of all cases. Vulnerability is exacerbated by high poverty, low literacy, and poor access to testing and treatment options. This study develops a community-engaged HIV prevention campaign plan for the Mayan town of Santiago Atitlán. The PEN-3 model of cultural sensitivity frames this formative research project. Assessment domains of the PEN-3 model (Cultural empowerment and Relationships & expectations) identify culturally relevant factors affecting HIV prevention behaviours. The Cultural identity domain is utilized to identify entry points enhancing cultural acceptance and efficacy.     

Biomechanical response to systematic changes in impact interface cushioning properties while performing a tennis-specific movement

It is currently not known whether human responses across typical sports surfaces are dependent on cushioning or frictional properties of the interface. The present study assessed systematic changes in surface cushioning (baseline acrylic, rubber, thin foam, and thick foam) as participants performed tennis running forehand foot plants wearing a basic neutral shoe (plimsolls). It was hypothesized that systematic decreases in peak rates of loading, heel pressures, and perceived hardness would be yielded as surface cushioning increased (impact test device). A common acrylic top surface provided consistent frictional properties across surfaces. Kinetics (AMTI, 960 Hz and Footscan Pressure Insoles, 500 Hz), kinematics (Peak MOTUS, 120 Hz), and cushioning perception were assessed. Peak and mean loading rates of vertical ground reaction force, peak horizontal force, peak heel pressure, and rates of loading demonstrated significant correlations (P < 0.05) with the participants' perceived levels of cushioning and matched mechanical rankings of surface cushioning. In contrast, peak impact force was lowest on the least cushioned surface. Kinematic responses were not significantly different between surfaces. Present evidence supports 'peak rate of loading' as a more suitable indicator of surface cushioning than peak impact force. Although cautionary, biomechanical support is also provided for mechanical methods of surface cushioning assessment.     

Individual differences in the interleukin-6 response to maximal and submaximal exercise tasks

The inflammatory responsive cytokine interleukin-6 (IL-6) helps regulate immune responses to exercise. Evidence suggests that increases in IL-6 are related to exercise duration and intensity. However, the moderating effect of sex and underlying mediators have received limited attention. We compared plasma IL-6 responses to two cycling tasks with a resting control in young male (n = 12) and female (n = 12) recreationally active adults. Both 45 min tasks comprised an incremental test, either maximal or submaximal, followed by steady-state exercise at 55% peak power output. Interleukin-6 was elevated above baseline immediately after the maximal but not the submaximal task. Compared with the control condition, IL-6 was increased at 30 and 60 min after both exercise tasks. The IL-6 response was greater in women than men at 60 min after maximal exercise. Cortisol increased in both tasks compared with the control condition, the increase being greater after maximal than submaximal exercise. No associations were found between IL-6 responses and cortisol, heart rate, fitness or body mass index. The results show that 45 min of moderate-intensity exercise can increase IL-6 and suggest that the inclusion of maximal effort may accelerate this response. The finding that women showed a greater IL-6 response to maximal exercise may reflect a gender dimorphism in the immune response to stress.     

Science teachers' views and practices in planning for teaching

This article studies the views and practices of a group of secondary school science teachers toward lesson planning. The two main questions posed are: “What do teachers do when they prepare their lessons?” and “What do teachers think of their own planning?” We describe the decisions made by the teachers, the things they take into account, what they give most importance to, the time spent, the source of their knowledge, and how they evaluate the results. The information was obtained by structured personal interviews, which were compared with reports written by the teachers. Our findings led us to reflect on ways in which lesson planning may be introduced into training programs. © 1999 John Wiley & Sons, Inc. J Res Sci Teach 36: 493–513, 1999     

Special Education in a 4‐Year Response to Intervention (RtI) Environment: Characteristics of Students with Learning Disability and Grade of Identification

This 4‐year longitudinal research was designed to study special education determinations of students who participated in Tier 2 intervention in a Response to Intervention (RtI) model focused on reading across Grades 1–4. We compared identification rates for learning disabilities (LD) and student characteristics of 381 students the year prior to implementation with 377 students in the RtI environment. Across schools, 38–60 percent of students were English language learners (ELL). Key outcomes by Grade 4 for students with LD who had participated in a model of RtI were relatively greater reading impairment with effect sizes ranging from 0.64 to 0.82, and more equitable representation across ELL and native English speakers than in the cohort prior to RtI implementation. Notably, one‐third of the students identified for special services as LD in these schools were not identified until 4th grade.     

Practice architectures and sustainable curriculum renewal

While there are numerous pedagogical innovations and varying forms of professional learning to support change, teachers rarely move beyond the initial implementation of new ideas and policies and few innovations reach the institutionalized stage. Building on both site ontologies and situated learning in communities of practice perspectives, this paper explores the theory of practice architectures to offer a different and legitimate perspective on sustainable curriculum renewal. Specifically, a practice architecture either enables or constrains particular practice and constitutes the construction of practice from semantic (e.g. language), social (e.g. power relations) and physical (e.g. materials) spaces. Through the juxtaposition of practice architectures with an empirical illustration of longer term pedagogical change, the paper argues that for pedagogical change to be sustained a practice architecture that relates to an innovation’s intended learning outcomes and the contexts in which an innovation can be used needs to be created. Consequently, the theory of practice architectures can guide reform programmes. Curricularists can begin programmes with a pre-planned approach to assist, (a) teachers’ understanding of how to use an innovation, and (b) the deconstruction and reconstruction of practice architectures to support an innovation’s survival.     

A model of career development for a multicultural work force

This article highlights a career development model (Coleman, 1989) designed for use with multicultural and diverse populations. Individuals from these backgrounds sometime encounter difficulties with their career development, and the model was created to focus on the particular issues, needs, and concerns of multicultural populations. The career development model consists of six components: 1) Introduction and Orientation; 2) Self-Assessment; 3) Decision Making; 4) Educational, Occupational, and Community Information; 5) Preparation for Work, Leisure, and Retirement; and 6) Research and Evaluation. A discussion of the barriers encountered by multicultural populations is included, along with implications for counseling and development professionals.     

Teaching Cases in a Virtual Environment: When the Traditional Case Classroom is Problematic

The rise in interactive digital media has catapulted faculty‐student contact abilities from the traditional Web 1.0 model to a post‐Web 2.0 world where students and faculty can have much more interaction in classroom exchanges. Since business cases have long been a pedagogy of choice among professors concerned with training the next generation of decision makers, the intent of this exploratory teaching execution was to gain insight into the case teaching experience in Second Life (SL). SL is a virtual world developed by Linden Lab that enables its users to interact with each other through avatars (virtual representations of the self). While online classrooms in SL are not new (a number of universities throughout the world have set up virtual campuses), business education scholarship is lacking as related to the use of virtual worlds for educational purposes. The aim of the execution was not to suggest that SL case teaching should displace the traditional case classroom interactions. Rather, the exercise found that a case‐based class can be held and attended independent of time, distance, and location should the need arise. Case teaching in SL offers an availability alternative or supplement to the traditional case teaching and learning approach.
