Age-related differences in rapid muscle activation after rate of force development training of the elbow flexors

In young adults, improvements in the rate of force development as a result of resistance training are accompanied by increases in neural drive in the very initial phase of muscle activation. The purpose of this experiment was to determine if older adults also exhibit similar adaptations in response to rate of force development (RFD) training. Eight young (21-35 years) and eight older (60-79 years) adults were assessed during the production of maximum rapid contractions, before and after four weeks of progressive resistance training for the elbow flexors. Young and older adults exhibited significant increases (P< 0.01) in peak RFD, of 25.6% and 28.6% respectively. For both groups the increase in RFD was accompanied by an increase in the root mean square (RMS) amplitude and in the rate of rise (RER) in the electromyogram (EMG) throughout the initial 100 ms of activation. For older adults, however, this training response was only apparent in the brachialis and brachioradialis muscles. This response was not observed in surface EMG recorded from the biceps brachii muscle during either RFD testing or throughout training, nor was it observed in the pronator teres muscle. The minimal adaptations observed for older adults in the bifunctional muscles biceps brachii and pronator teres are considered to indicate a compromise of the neural adaptations older adults might experience in response to resistance training.

Voices of lay principals: Promoting a Catholic character and culture in schools in an era of change

This paper reports a qualitative study of the practice of leadership in Catholic schools to ascertain the perceptions of lay principals, who as positional leaders play a critical role in embracing and creatively rebuilding the Catholic vision of life within the reality that the Catholic school principalship is now a ministry of the laity. The methodology included semi-structured interviews, field notes, reflexive journals, direct observation, and document nalysis. The study examined both individual human behaviour and the structure of the social order in Catholic schools. The findings point towards successful leadership in Catholic schools being highly influenced by the cultural and spiritual capital that a principal brings to a school signifying a fundamental importance of appointing principals who are not only professionally competent but spiritually as well. In an era of unprecedented social, educational and ecclesial change, and with an ever widening role description, lay principals are challenged to redefine and re-articulate their Catholic character and identity, and will need to look for new ways to make this explicit. Embracing a new leadership paradigm of shared leadership, the preparation and on-going formation of lay principals were identified as critical for the continuance of the Catholic school’s distinctive mission in the future.

Becoming a therapist: Challenging the role of training - An interview with Ernesto Spinelli

Research appears to indicate that the personal qualities of the therapist really count in effective therapy. Brian Sullivan from the University of Queensland asks Professor Ernesto Spinelli for his opinion on the vexing questions that arise when this knowledge is considered in the effective training of therapists. What are the significant personal qualities and how do we identify them? Are good therapists born with the raw material to start with, or can anyone be trained to become a therapist? Is personal development an essential component of any professional therapeutic training? If so, how do you incorporate it into a training program? What are the essential criteria in a successful selection process of trainees? (editor abstract)

English teachers' choice of language for publication: Qualitative insights from Bangladesh

The aim of this small-scale research was to gain some understanding of Bangladeshi English language teachers' language preference for publication purposes & the extent of the use of Bangla (Bengali), the L1, in their professional practice. Qualitative data for the study were gathered by means of a self-produced questionnaire. Results show that about three-quarters of the teachers published or would publish entirely in English because they believed that it was, among other reasons, the usual professional practice. More importantly, a number of teachers stated that they felt more comfortable writing academic essays in English. Regarding the use of L1, all 37 respondents pointed out that they used it sparingly in the classroom, & only a small number considered it a barrier in learning English, the L2. While emphasising the study's limitations, the paper suggests that English teachers' lack of confidence in L1 academic writing may be seen as indicating the potential direction of a slowly emerging individual bilingualism among university teachers of English. However, the paper also argues that the emergence of this potential bilingualism can be seen only at the individual rather than societal level, &, within the academic context, only in the limited domain of academic writing.
