The effect of acceleration signal processing for head impact numeric simulations

Brain injury research in sport employs a variety of physical models equipped with accelerometers. These acceleration signals are commonly processed using filters. The purpose of this research was to determine the effect of applying filters with different cutoff frequencies to the acceleration signals used as input for finite element modeling of the brain. Signals were generated from reconstructions of concussion events from American football and ice hockey in the laboratory using a Hybrid III headform. The resulting acceleration signals were used as input for the University College Dublin Brain Trauma Model after being processed with filters. The results indicated that using a filter with a cutoff of 300 Hz or higher had little effect on the resulting strain measures. In some cases there was some effect of the filters on the peak linear (8–30g) and rotational measures (1000–4000 rad/s²), but little effect on the finite element strain result (approximately 2–6 %). The short duration and high magnitude accelerations, such as the puck impact, were most affected by the cutoff frequency of different filters.     

Profile analysis of standardized intelligence test performance of very high IQ children

Practitioners are frequently faced with the need to evaluate the intellectual skills of individuals with very high levels of functioning. Due to the statistical rarity of these persons, few tests have sufficient range of scores for a detailed analysis of intraindividual differences in performance. This paper describes a method using age equivalents and standard scores to recreate the full range of variability in the scores of high-functioning individuals. The method allows for a more complete interpretation of performance that can lead to better educational and therapeutic programming.     

Parenting the gifted adolescent

Parenting gifted adolescents requires democratic and androgynous parenting practices to provide the guidance that gifted students look for as they grow toward adulthood.     

INTRODUCTION TO THE SPECIAL ISSUE OF EDUCATIONAL GERONTOLOGY: INTERDISCIPLINARY GERIATRIC EDUCATION IN THE HEALTH CARE PROFESSIONS: THE DEVELOPMENT,IMPLEMENTATION, AND EVALUATION OF PROGRAMS IN THE RHODE ISLAND GERIATRIC EDUCATION CENTER

The interest around intergenerational programs and the fostering of intergenerational relationships is growing internationally. However, studies on the profile and functions of intergenerational program managers are still scarce. Furthermore, available approaches to the traits and functions of intergenerational program managers have not highlighted which features are distinctive of these professionals. Through a Delphi study undertaken in Spain, with participation of 18 intergenerational program managers and 12 intergenerational specialists, consensus was reached around characteristics of both the general profile of intergenerational program managers and the specificities of this occupational role. On the one hand, being able to work on a team, having skills for observation and contextual analysis, and being skilled at managing resources were identified as the most important general characteristics. On the other hand, being good at promoting contacts, social relationships, interactions, and bonds was deemed to be the most distinctive feature of this profile. After contrasting our results with international guidelines and standards for intergenerational work, the need to develop and reinforce further the relational nature of this professional figure is argued.     

The Impact of Tier 2 Mathematics Instruction on Second Graders with Mathematics Difficulties

Although research on Tier 2 interventions for early mathematics is accumulating, such efforts remain far behind those for reading, especially regarding specific features such as the ideal time to begin an intervention. The present study investigated the effectiveness of a Tier 2 intervention using a single subject multiple baseline, across-groups design with two cohorts of second graders. Because the two cohorts of students were given the intervention at different times during the second grade year, the study also documented whether the timing of the intervention affected acquisition and retention of second grade mathematics competencies. Finally, the study tracked student performance up to the first semester of the third grade year to document any sustained effects. The results show that the supplemental intervention was effective for both cohorts, but differences in performance indicate that the timing of the intervention may affect the degree of success. In addition, for some participants, the positive effects of the intervention were sustained into the third grade year.     

A Personal Theory of Teaching Computing Through Final Year Projects

Stated learning objectives for final year projects tend to be fairly generic. As a result, individual students' experience of project work will depend heavily on the attitudes and beliefs of their supervisor. This paper questions the purpose of projects in the computing curriculum and proposes a personal theory of teaching through projects. In deciding whether such a personal theory should emphasize disciplinary specific content or an experiential approach to learning we consider teaching and learning as a process of enculturation. The personal theory of teaching proposed envisages projects as an opportunity for students to engage in realistic activity which allows them to learn something of the nature of the discipline. The student may be thought of as being on a journey, while the supervisor takes the role of a guide pointing out alternatives along the route but allowing students ultimately to find their own way.
