The diverse body of international schools continues to grow and develop. Yet, the realities of being a leader in such a school continue to be neglected by discussion and research. It is acknowledged that international schools are complex organizations to lead and manage, with numerous boundaries, transient stakeholders, and opposing priorities. They exist as very challenging arenas for leadership, ripe for conflict and tension. This article uses anonymized comments on the social media website internationalschoolreview.com (ISR.com) to explore how and why teachers might post negative comments on school leaders. The framework of the “toxic triangle” is used as an instrument for presenting the comments. The article then discusses the implications for leadership practices. In particular, the comments on ISR.com reveal how isolated international schools are, with seemingly few options for teachers to release the “pressure valve” if unhappy or unsatisfied by what they might deem to be unethical and immoral leadership behavior. Further, the comments show how loosely coupled and fragmented the schools are, and many of the teachers themselves exist in a precarious state of anxiety. Overall, the comments add substantial weight to the argument that international schools are complex and challenging leadership environments. 相似文献

Abstract This study was designed to investigate the effect of ingesting a glucose plus fructose solution on the metabolic responses to soccer-specific exercise in the heat and the impact on subsequent exercise capacity. Eleven male soccer players performed a 90 min soccer-specific protocol on three occasions. Either 3 ml · kg?1 body mass of a solution containing glucose (1 g · min?1 glucose) (GLU), or glucose (0.66 g · min?1) plus fructose (0.33 g · min?1) (MIX) or placebo (PLA) was consumed every 15 minutes. Respiratory measures were undertaken at 15-min intervals, blood samples were drawn at rest, half-time and on completion of the protocol, and muscle glycogen concentration was assessed pre- and post-exercise. Following the soccer-specific protocol the Cunningham and Faulkner test was performed. No significant differences in post-exercise muscle glycogen concentration (PLA, 62.99 ± 8.39 mmol · kg wet weight?1; GLU 68.62 ± 2.70; mmol · kg wet weight?1 and MIX 76.63 ± 6.92 mmol · kg wet weight?1) or exercise capacity (PLA, 73.62 ± 8.61 s; GLU, 77.11 ± 7.17 s; MIX, 83.04 ± 9.65 s) were observed between treatments (P > 0.05). However, total carbohydrate oxidation was significantly increased during MIX compared with PLA (P < 0.05). These results suggest that when ingested in moderate amounts, the type of carbohydrate does not influence metabolism during soccer-specific intermittent exercise or affect performance capacity after exercise in the heat. 相似文献

Proposing an enhancement to the concepts of verbal and corporeal rhetorics, this article offers the concept of aural body rhetoric, arguing that nonvocal sounds produced by the body can also provide rhetorical messages, create rhetorical challenges and prompt the conscious management of bodily sounds, particularly in panopticonic spaces (panauricons) in which the body is hidden from view. Using the urinary sounds made by transsexual men in public restrooms as an example, this article examines this space as a panauricon that creates a rhetorical challenge for these men and has prompted the dissemination of various rhetorical strategies within the community of transmen in the United States. 相似文献

The past decade has seen the emergence, predominantly in Thailand and mainland China, of a form of educational institution that has had little scholarly attention or generic identification. This paper shows how the ad hoc and opportunistic franchising of elite English private schools, beginning with the hyper-capitalist exportation of the Dulwich College “brand” to Phuket in 1996, led to the emergence of a quasi-market involving the “satellite college”. This paper charts the development of this educational experiment and shows how a distinct “second wave” is beginning to appear: The Charities Act of England and Wales 2006 has put pressure on charitable-status elite private schools in England to subsidise places for low-income students. As a result, the satellite college model looks set to appear in a more systematic manner and beyond Asia. This paper discusses this model of hyper-capitalism as it enters a seemingly more problematic and controversial phase of development. 相似文献
