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.

Civil society as a contested field of meanings

Purpose – During recent years, the concept of civil society, particularly global civil society, has come to the fore in both academia and policy circles. A key component of recent theoretical and policy research is the attempt to do international comparative research on the meaning of civil society. The purpose of this paper is to argue that the language and the terminology used to describe the agents of civil society are reflective of cultural and historical contexts of societies, have distinct meanings and cannot be used interchangeably.

Design/methodology/approach – In different national contexts, the key agents of civil society are referred to differently; nonprofit sector, voluntary and community sector, third sector and social economy. In comparative studies, scholars often list these concepts to indicate that they recognise that the agents of civil society are referred to differently in different societies. The article offers a socio-historical analysis of each concept. It is concluded that teasing out the differences, as well as the similarities, between the nonprofit sector, voluntary and community sector, third sector and social economy, is crucial to robust comparative research on civil society.

Findings – This paper exposes a number of limitations of each of the terminologies used to describe civil society. They all present a much more limiting notion of civil society than that proposed by the founding fathers. None seem to capture the range of civil associations in any society. Yet, assumptions are made that the terminologies used have similar meanings rather than attempting to clarify and define exactly what is being written or described. This is exacerbated by the interchangeable usage of nonprofit/third sector/community and voluntary sector/social economy. In order to progress beyond culturally specific understandings of civil society, it is necessary to examine the terminology used and how it emanates from a specific cultural and political context. Having a clear understanding of the language used and what it signifies is crucial to robust cross-national comparative research.

Originality/value – This paper examines context specific understandings of civil society and the terminology used to define it; a question not previously addressed. It is hoped that this article will generate much needed further debate on cross-national meanings of civil society.

The conflict between realism and abstraction in the field of spanish art as an iteration of la "Querelle des Anciens et des Modernes"

Based on the analysis model favored by the study of the conditions in which the seventeenth century Querelle des Anciens et des Modernes took place, we examine the case of confrontation between realism and abstraction, which occurred in the context of Spanish art in the nineties of the twentieth century. Connections are established with other aesthetic conflicts which are considered part of a genealogy whose most explicit antecedent could be placed in the before mentioned complaint, such as the confrontation between realism and abstraction in the American art scene, which occurred in the fifties of the last century, and the more recent controversy on pluralism and the end of art.

Systemic psychotherapy as an intervention for post-traumatic stress responses: an introduction, theoretical rationale and overview of developments in an emerging field of interest

The purpose of this article is to critically examine the literature to provide a rationale for including systemic family therapy (SFT) in the psycho-social treatment of people suffering the impact of post-traumatic stress (PTS). Attention is drawn to the relatively underdeveloped academic literature on PTS and the family. The impact of PTS is conceptualized within a psycho-social framework and the current evidence base for psycho-social interventions for PTS responses is described, highlighting the opportunity and need to undergird this area of daily practice. The impact of PTS on the family at multiple levels is identified, emphasizing its recursive nature. The case for SFT is articulated and a range of models of family intervention for PTS briefly reviewed, concluding with an emphasis on Walsh's key processes in family resilience as a framework for practice.

Second-order NMR spectra at high field of common organic functional groups

The proton NMR spectra of aryl n-propyl sulfides gave rise to what may appear to be first-order proton NMR spectra. Upon oxidation to the corresponding sulfone, the spectra changed appearance dramatically and were clearly second-order. A detailed analysis of these second-order spectra, in the sulfone series, provided vicinal coupling constants which indicated that these compounds had a moderate preference for the anti-conformer, reflecting the much greater size of the sulfone over the sulfide. It also emerged, from this study, that the criterion for observing large second-order effects in the proton NMR spectra of 1,2-disubstituted ethanes was that the difference in vicinal coupling constants must be large and the difference in geminal coupling constants must be small. n-Propyl triphenylphosphonium bromide and 2-trimethylsilylethanesulfonyl chloride, and derivatives thereof, also exhibited second-order spectra, again due to the bulky substituents. Since these spectra are second-order due to magnetic nonequivalence of the nuclei in question, not chemical shifts, the proton spectra are perpetually second-order and can never be rendered first-order by using higher field NMR spectrometers.

W(h)ither New Age studies? The uses of ethnography in a contested field of scholarship

Since the 1980s, there has existed a field of scholarly inquiry into a range of phenomena termed New Age. The relative lack of ethnographic studies in this field was identified several years ago, in response to research that focused merely on the discourses within alleged key writings. However, the employment of ethnographic methods does not by itself resolve the problems inherent in other modes of research; attention also has to be paid to how ethnography is used in practice. This article examines ethnographies of the New Age in terms of the extent to which they contextualize data within their immediate social frames, by paying attention to actors’ practices and interactions, and to the ways in which beliefs and discourses are constructed and contested. The article demonstrates the strong tendency among New Age ethnographic studies to veer from ‘the social’ and to rest instead on analytically problematic conceptualizations of agency. It argues that epistemological revision is required to form the basis of a more sociologically adequate understanding of the phenomena addressed.

Güler and Öngel v Turkey: Article 3 of the European Convention on Human Rights and Strasbourg’s discourse on the justified use of force

This article discusses the discourse on the justified use of force in the Strasbourg Court’s analysis of Article 3. With particular focus on the judgment in Güler and Öngel v Turkey, a case concerning the use of force by State agents against demonstrators, it addresses the question of the implications of such discourse, found in this and other cases, on the absolute nature of Article 3. It offers a perspective which suggests that the discourse on the justified use of force can be reconciled with Article 3’s absolute nature.
