ABSTRACT

The spirit of capitalism shifted throughout the twentieth century, Boltanski and Chiapello place it sometime in the period between the 1960s and 1990s [2005, The New Spirit of Capitalism, Verso, London], for Bell it had happened by the mid-1970s and its contradictions were already apparent [1998, The Cultural Contradictions of Capitalism, Basic Books, New York]. David Harvey is more specific and cites 1979 as the dawn of the new era [2005, The New Spirit of Capitalism, Verso, London]. This paper seeks to build on this scholarship of the changing spirit of capitalism and read it through the development of the heroic figure of the American imagination, through the representation of the capitalist hero. Its aim is to situate the figure of the capitalist hero in the post-crash era and ultimately to understand the seductive power of the new capitalism that enables it to thrive. My thesis is that the seductive power of the new capitalism can be understood as an oscillation between revulsion and awe, we are both morally repulsed by the venality of capitalism yet also captivated by it. Revulsion and awe are at the core of the libidinality of the new capitalism and can be seen through the representation of the heroic object of the capitalist imagination.  相似文献

Prospective application of serum cytokines, lipopolysaccharide (LPS), and heat shock proteins (eHSPs) requires reliable measurement of these biomarkers that can signify exercise-induced heat stress in hot conditions. To accomplish this, both short-term (7 day) reliability (at rest, n = 12) and the acute responsiveness of each biomarker to exercise in the heat (pre and post 60-min cycling, 34.5°C and 70% RH, n = 20) were evaluated. Serum was analysed for the concentration of C-reactive protein (CRP), interleukin-6 (IL-6), heat shock protein 72 (eHSP72), immunoglobulin M (IgM) and LPS. Test–retest reliability was determined as the coefficient of variation (CV). Biomarkers with the least short-term within-participant variation were IL-6 (19%, ±20%; CV, ±95% confidence limits (CL)) and LPS (23%, ±13%). Greater variability was observed for IgM, eHSP72 and CRP (CV range 28–38%). IL-6 exhibited the largest increase in response to acute exercise (95%, ±11%, P = < 0.001) and although CRP had a modest CV (12%, ±7%), it increased substantially post-exercise (P = 0.02, ES; 0.78). In contrast, eHSP72 and LPS exhibited trivial changes post-exercise. It appears variation of common inflammatory markers after exercise in the heat is not always discernible from short-term (weekly) variation.  相似文献

ABSTRACT

The shifting constitution of journalists as humanitarian actors has profound implications for changing forms of journalism practice, as well as for the normative models through which journalists understand and reflect on that practice. In an effort to develop a more empirically-grounded engagement with change, this article explores the interview testimonies of Australian journalists who cover international and humanitarian issues. It argues that frameworks reliant on stark oppositions (between past and present, optimism and pessimism, or moral agency and material structure) are both empirically and practically problematic, and seeks to move beyond these. Engagement with data from semi-structured interviews offers insight into how journalists’ perceptions of and responses to change are shaped by the historical and shifting institutional relations in which they are implicated.  相似文献

This study evaluated whether exposing junior netball players to greater amounts of competition relevant activity (playing form activity) had an effect on game play outcomes and session involvement. A group-randomised controlled trial in one junior netball club in the Hunter Region, NSW, Australia. Ninety female athletes (mean age = 9.04 years, SD 1.53) were randomised by team (n = 11) into the intervention (n = 41) or 9-week wait-list control (n = 49) condition. The Professional Learning for Understanding Games Education into Sport (PLUNGE into Sport) programme was undertaken in the first half of nine training sessions (9 × 30 min). The intervention exposed athletes to playing form activity through a coach development programme within training sessions. Athletes’ decision-making, support and skill outcomes during a small-sided invasion game, and session involvement (pedometer step/min), were measured at baseline and 9-week follow-up. Linear mixed models revealed significant group-by-time intervention effects (P < 0.05) for decision-making (d = 0.4) and support (d = 0.5) during game play, and in-session activity (d = 1.2). An intervention exposing athletes to greater levels of playing form activity, delivered via a coach education programme, was efficacious in improving athlete decision-making and support skills in game play and increasing athlete involvement during sessions.  相似文献

The purpose of this study was to investigate the accuracy of fat-free mass (FFM) estimates from two-compartment (2C) models including air displacement plethysmography (ADP), ultrasound (US), near-infrared interactance (NIR), and the Jackson and Pollock skinfold equation (SKF) against a criterion four-compartment (4C) model in elite male rowers. METHODS: Twenty-three elite-level male rowers (mean± SD; age 24.6 ± 2.2 years; stature: 191.4 ± 7.2 cm; mass: 87.2 ± 11.2 kg) participated in this investigation. All body composition assessments were performed on the same day in random order, except for hydrostatic weighing (HW), which was measured last. FFM was evaluated using a 4C model, which included total body water from bioimpedance spectroscopy, body volume from HW, and total body bone mineral via dual-energy X-ray absorptiometry. The major findings of the study were that the 2C models evaluated overestimated FFM and should be considered with caution for the assessment of FFM in elite male rowers. Future studies should use multiple-compartment models, with measurement of TBW and bone mineral content, for the estimation of FFM.  相似文献
