Principal selection: homosocialibility, the search for security and the production of normalized principal identities

Researchers investigating the decline of potential applicants for principalships have demonstrated that teachers perceive there to be a significant problem in current selection procedures. This article reports an investigation in two Australian states into principal selection. Drawing on a corpus of interviews, two case studies and administrative guidelines, we highlight five key problems in the interview process: (1) the dependence of selection panels on a written application; (2) the dilemma of experience versus potential; (3) the covert rule about the appointment of preferred applicants; (4) the quandary of panel competency; and (5) the evidence of inconsistency of decisions. We argue that the selection process amounts to a reproductive technology which, in the quest for certainty and safety, results in particular kinds of people being successful. This amounts we suggest, whether the selection process is managed by progressive or conservative personnel, to a form of homosociability the tendency to select people just like oneself.

Homophobia and the production of shame: young people and same sex attraction

Research among same-sex attracted young people in Western cultures has described a minority group of adolescents whose sexuality is negated by the significant institutions and people in their lives. Very often, there is a silence in the family and at school about same-sex sexuality and when a young person's homosexuality is suspected or disclosed s/he suffers from denial, discrimination and abuse. Not surprisingly, living in hostile environments leaves such young people at high-risk of drug abuse, depression and suicide. This paper describes some of the ways young people resist being positioned in these negative ways. Using autobiographical stories from 200 same-sex attracted young Australians, we document the discursive field of sexuality in which these young people struggle to construct positive identities. Young people were well aware of dominant discourses which characterized homosexuality as 'evil, diseased and unnatural'. Yet they use different strategies to fault, deflect and discount these negative understandings and to highlight other discourse which positions them positively.

Are oil shocks permanent or temporary? panel data evidence from crude oil and NGL production in 60 countries

This paper examines the unit root properties of crude oil production for 60 countries employing a range of panel data unit root tests for the period 1971 to 2003. The study first employs a number of panel data tests that do not accommodate structural breaks and then proceeds to apply the Lagrange Multiplier (LM) panel unit root test with one structural break. The results of the panel data tests without a structural break are inconclusive with at best mixed support for joint stationarity. The findings from the LM panel unit root test with a structural break, however, are conclusive, suggesting that for a world panel and smaller regional-based panels, crude oil and NGL production are jointly stationary.

The fine line between harm reduction and harm production - development of a clinical policy on femoral (groin) injecting

The femoral region ('groin') appears to be increasingly commonly used by injecting drug users in the UK. With the advent of Britain's first supervised prescribed injectable opioid treatment clinic, unprecedented decisions and judgements were required about the safe supervision of this practice, or whether to permit this behaviour on site at all. This paper reports the reasons for, and outcome of, development of a clinical policy on injecting into the deep femoral vein (groin injecting)

Kristevan aesthetics, performativity and the production of situated knowledge

In this paper, I will draw on the work of Julia Kristeva to argue that performativity can be understood in terms of a materialist ontology that underpins creative production and the knowing subject. To understand this, we need to examine the relationship between individual history, biology and culture and processes through which creative practice attributes value by translating psychic representations of affect and drive into verbal and visual signs. Kristeva's aesthetics does not plunge us into an obscure metaphysics, but provides a model for articulating material-discursive practices that emerge from corporeal responses. Enactments, predicated by desire give rise to agency and judgement allowing practice to test theory through the production of situated knowledge.

Kristeva's psychoanalytical position reveals the necessity of linking material and individual practices of art with the social through language and interpretation. Material-discursive practices can only acquire meaning through their relationship between the speaking subject and addressees. Art itself provides us with the means for discovering the knowledge it produces. In and through material practice, the work of art is capable of transferring back to the artist as viewer, structures of meaning that have hitherto been hidden. In practice, this involves a constant movement between the biological self (the self as 'other') and the social self, the ego. In artistic research, it can be said that the first addressee is the artist her/himself, as social other. Constant movement between the two in creative practice can thus be understood as a performative production of knowledge.

Environmental art and the production of publics : responding to environmental change

Environmental crises around the world have inspired an outpour of creative response. As the effects of climate change increasingly manifest, environmental! art is being politically and pedagogically mobilised for ameliorative strategies. The rubric that instrumentalist, techno-scientific approaches to environmental stress (and attendant social distress) cannot solely provide solutions to this challenge has found increasing acceptance. The concern of this paper, however, is the limited understanding of public art's capacity that is perpetuated bv certain trends in environmental art in which the work is charged with communicative responsibility,. Connected to the representational and instructive traditions of public art, this tendency is further informed by the influence of the 'information-deficit model' in environmental conmunication research: a concept that asserts a straightforward connection between information provision, indiyidual awareness and collective action on a concern. The idea that public art can function as a conduit for knowledge,.which in turn will inspire new moral positions and behaviours, absents the art work from the process of knowledge-making and the production of conditons that enable new practice. Arguing for a revised approach to the environmental possibilities of public art, this paper will propose that in thinking aboutl environmental transformation as essentially unrepresentable, a dfferent mode of public engagement with the issue is enabled.

The relationship between Fiji Sugar Corporation's profitability and sugarcane production: an empirical assessment

The Fiji Government's inability to resolve the differences over land leases is widely seen as a major contributor to the difficulties experienced by the sugar industry. In this paper, however, a different perspective is provided on the industry's problems. In examining the relationship between the profitability of the Fiji Sugar Corporation and sugarcane production, it is found that profitability has had a statistically significant negative effect on sugarcane production, leading to the conclusion that the Fiji Sugar Corporation has been inefficient in the management of the mills, the rail transport system, and sugarcane research.

Separating the contributions of hearing, lexical knowledge and speech production to speech perception scores in children with hearing impairments.

Open-set word and sentence speech-perception test scores are commonly used as a measure of hearing abilities in children and adults using cochlear implants and/or hearing aids. These tests are usually presented auditorily with a verbal response. In the case of children, scores are typically lower and more variable than for adults with hearing impairments using similar devices. It is difficult to interpret children's speech-perception scores without considering the effects of lexical knowledge and speech-production abilities on their responses. This study postulated a simple mathematical model to describe the effects of hearing, lexical knowledge, and speech production on the perception test scores for monosyllabic words by children with impaired hearing. Thirty-three primary-school children with impaired hearing, fitted with hearing aids and/or cochlear implants, were evaluated using speech-perception, reading-aloud, speech-production, and language measures. These various measures were incorporated in the mathematical model, which revealed that performance in an open-set word-perception test in the auditory-alone mode is strongly dependent on residual hearing levels, lexical knowledge, and speech-production abilities. Further applications of the model provided an estimate of the effect of each component on the overall speech-perception score for each child.

Impact of training on changes in perceived stress and cytokine production

Data on training of competitive athletes and the inflammatory response, and, more specifically, the utility of psychological inventories to monitor this response in regards to overreaching is limited. The aim of the present study was to investigate the association of the Perceived Stress Scale (PSS) and inflammatory markers in elite rowers. Eight rowers (males n = 4; females n = 4) were monitored over an 8-week training period, comprising 12 sessions each week and training an average 3.11 h·d-1. Training volume was periodized weekly while intensity was maintained throughout the study. Perceived stress was measured weekly pretraining, and capillary blood samples (500 μL) were taken post-training. Significant associations between perceived stress and cytokines interleukin-6 (p < .05) and tumor necrosis factor alpha (p < .05) were observed. While further investigation of the role of cytokines in the overtraining process is required, these data provide preliminary support for an association between perceived stress and the inflammatory responses to training.

The aesthetic image : affect and the production of knowledge in practice-led research

This paper addresses the question of how we might provide practitioners with a framework for understanding how affect and aesthetic processes generate images that are implicated in the production of new knowledge in creative arts research. Drawing on the thought of Julia Kristeva, it examines the aesthetic underpinnings of discovery and the significance of this for research training and the development of more effective pedagogies both within and beyond the university.

Influence of stocking rate and mixed grazing of Angora goats and Merino sheep on animal and pasture production in southern Australia : 1 : botanical composition, sward characteristics and availability of components of annual temperate pastures

The effects of animal species (AS; Angora goats, Merino sheep or goats and sheep mixed grazed together at ratio 1:1) and stocking rate (SR; 7.5, 10 and 12.5 animals/ha) on the availability, botanical composition and sward characteristics of annual temperate pastures under continuous grazing were determined in a replicated experiment from 1981 to 1984. AS and SR had significant effects on pasture availability and composition and many AS SR interactions were detected. The pastures grazed by sheep had significantly reduced content and proportion of subterranean clover and more undesirable grasses compared with those grazed by goats. There were no differences in dry matter availabilities between goat- and sheep-grazed pastures at 7.5/ha, but at 10 and 12.5/ha goat pastures had significantly increased availabilities of green grass, dead and green clover and less weeds compared with sheep pastures. There was a significant AS SR interaction for the density of seedlings in May following pasture germination. Between July and January, the height of pastures was greater under goats than sheep but from January to March pasture height declined more on goat-grazed than on sheep-grazed pastures. There was an AS SR interaction for incidence of bare ground. Increasing the SR increased bare ground in pastures grazed by sheep but no change occurred on pastures grazed by goats. Changes in pasture characteristics due to increased SR were minimised on pastures grazed by goats but the grazing of sheep caused larger and faster changes and the pastures were damaged at the highest SR. Goats did not always select the same herbage material as sheep, changed their selection between seasons and were not less selective than sheep. Angora goats were flexible grazers and continually adapted their grazing behaviour to changing herbage conditions. Goat grazing led to an increase in subterranean clover, an accumulation of dead herbage at the base of the sward, reduced bare ground, taller pastures in spring and a more stable botanical composition. Mixed-grazed pasture characteristics were altered with SR. With careful management Angora goats on sheep farms may be used to manipulate pasture composition, to speed up establishment of subterranean clover, to decrease soil erosion and to reduce weed invasion.

Influence of stocking rate and mixed grazing of Angora goats and Merino sheep on animal and pasture production in southern Australia : 2 : liveweight, body condition score, carcass yield and mortality

The effects of animal species (AS; Angora goats, Merino sheep, mixed-grazed goats and sheep at the ratio of 1:1) and stocking rate (SR; 7.5, 10 and 12.5 animals/ha) on the liveweight, body condition score, carcass yield and mortality of goats and sheep were determined in a replicated experiment on improved annual temperate pastures in southern Australia from 1981 to 1984. The pattern of liveweight change was similar for both species with growth from pasture germination in autumn until maturation in late spring followed by weight loss. In winter, sheep grew faster than goats (65 versus 10 g/day, P < 0.05). In mixed-grazed treatments between November and December goats either grew when sheep were losing weight or goats lost less weight than sheep (P < 0.01). Both AS (P < 0.001) and SR (P < 0.001) affected liveweight of sheep and an AS SR interaction (P <  0.05) affected liveweight of goats. Mixed-grazed sheep were heavier than separately grazed sheep at all SR with a mean difference at 10 and 12.5/ha of 4.6 kg. Mixed-grazed goats at 10/ha were heavier than separately grazed goats from the end of the second year of the experiment, but at 12.5/ha, separately grazed goats maintained an advantage over mixed-grazed goats, with a 9.4-kg mean difference in December (P < 0.05). Body condition scores of goats and sheep declined with increasing SR; they were highest in late spring and were highly correlated with liveweight (r² > 0.8). Both AS and SR affected (P < 0.001) carcass weight and GR tissue depth as a direct result of differences in liveweight. Adjusting for differences in carcass weight negated AS effects on GR tissue depth. The carcass weights of sheep and goats increased by similar amounts for each 1-kg increase in liveweight. Mortality of sheep (3.1% p.a.) was unaffected by AS or SR. An AS SR interaction indicated mortality of separately grazed goats at 12.5/ha and mixed-grazed goats at 10 and 12.5/ha were higher (P < 0.05) than all other goat (29 versus 9%) and sheep treatments, primarily because of increased susceptibility to cold stress. Disease prevalence differed between sheep and goats. Mixed grazing of Merino sheep and Angora goats produced complementary and competitive effects depending upon the SR. Goats used summer pasture better but winter pasture less well for liveweight gain than sheep. Angora goats should not be grazed alone or mixed grazed with sheep on annual temperate pastures at SR greater than that recommended for Merino sheep and the evidence indicates a lower SR will reduce risks associated with mortality.
