Research in Special Needs Education: Objectivity or Ideology?

Social science, including research into special educational needs, purports to be objective, and much of special needs research falls into the empirical-analytic paradigm which regards human affairs as containing measurable, law-like qualities to be identified and manipulated. It is argued, however, that this may be a flawed assumption and that all researchers need to be aware of the potentially political nature of their position. The sources, for instance, of a physical disability need to be located, not in the physical problem per se , but within the way society seeks to deal with it. Although researchers may like to view themselves as impartial seekers of the truth, it is suggested that research techniques themselves emerge from a theoretical position which reflects their beliefs, values and dispositions towards the world. They also gain, directly or indirectly, from the research process in terms of kudos or academic recognition. A tentative alternative paradigm is presented which attempts to challenge the 'normalisation' approach to teaching those designated as having special needs.     

'You're Hopeless I Swear to God': Shifting masculinities in classroom talk

In this article the author aims to problematise the discourse of masculinity in the co-educational classroom. Moving strategically sideways to focus on boys rather than girls, it is argued that 'masculinity' is not a fixed essence but a shifting gendered social identity. Although mass culture generally assumes there is a fixed, true masculinity, not all boys and men take up the same kind of masculinity, nor do they experience 'maleness' in the same way. Social class and subcultures (as well as other inflections of identity not discussed in this article) profoundly affect the presentation and representation of masculine identities. Moreover, masculinity as a particular configuration of gender is constituted in relation to local contexts within the meritocratic discourse of schooling. The ethnographic data in this article, which focuses on boys relating to girls in the classroom, show how varied the contexts of gender production can be even within the same roughly parallel configurations of task and location. It is concluded that masculinity is above all a social identity accomplishment.     

Effects of acute 60 and 80% VO2max bouts of aerobic exercise on state anxiety of women of different age groups across time

The purpose of this investigation was to study the effects of an acute bout of aerobic exercise on state anxiety of women while controlling for iron status (hemoglobin and serum ferritin). Participants were 24 active women, ages 18-20 years (n = 12) and 35-45 years (n = 12). In addition to a nonexercise control condition, participants completed one exercise bout at 60% maximal oxygen uptake (VO2max) and one at 80% VO2max. Each exercise session consisted of a 33-min bout in which participants exercised at their target intensities for a 20-min segment. Immediately before each exercise trial, participants were given the Spielberger State Anxiety Inventory (SAI). The SAI was again administered immediately following the exercise session and at 30, 60, and 90 min postexercise. Data were analyzed using an Age x Intensity x Time (2 x 3 x 5) repeated measures analysis of covariance (ANCOVA) with iron status serving as the covariate. The ANCOVA on state anxiety yielded significant effects for time (p < .0001, eta2(p) = .48), the Intensity x Time interaction (p = .0006, eta2(p) = .19), and the Intensity x Age interaction (p = .04, eta2(p) = .15). All three exercise conditions (including control) showed a decline in state anxiety across time, but the 80% VO2max condition showed a sharper decline. Intensity of exercise conditions did not differ in state anxiety at baseline or immediately after exercise, but a difference favoring the 80% VO2max condition over the control condition emerged at 30 min postexercise. After controlling for iron status, older women who exercised at 80% VO2max exhibited lower SAI scores compared to the control condition.     

Inspiratory muscle fatigue in swimmers after a single 200 m swim

Inspiratory muscle fatigue may occur in as little as 6 min during high-intensity spontaneously breathing exercise. The aims of this study were to determine whether inspiratory muscle fatigue occurs during swimming exercise and whether inspiratory muscle strength differs between the supine and standing body positions. Seven competitive swimmers were recruited to perform a single 200 m front-crawl swim, corresponding to 90-95% of race pace. Inspiratory muscle strength was measured at residual volume using a hand-held mouth pressure meter that measured maximal inspiratory pressure in the upright and supine positions. At baseline, maximal inspiratory pressure in the supine position was significantly lower than maximal inspiratory pressure in the upright position (112 +/- 20.4 and 133 +/- 16.7 cmH2O, respectively; P < or = 0.01). Post-exercise maximal inspiratory pressure in the supine position (80 +/- 15.7 cmH2O) was significantly lower than baseline maximal inspiratory pressure in the supine position (P < or = 0.01). The results indicate that a single 200 m front-crawl swim corresponding to 90-95% of race pace was sufficient to induce inspiratory muscle fatigue in less than 2.7 min. Furthermore, although diaphragm muscle length is optimized when supine, our results indicate that the force output of the diaphragm and inspiratory accessory muscles is greater when upright than when supine.
