The arguments for, and justification of, the value of teaching art in school have been made previously, but contextually these are often situated in Western affluence. This article explores the issues with a strikingly contrasted setting. The rural school in the study is approximately 30 minutes' drive from the nearest town, and the pupils are drawn from the surrounding rural bush area which is itself developmentally and materially poor in comparison to the UK. In school, the poverty seemed initially to relate to a lack of educational resources, but the reality experienced in the classroom may have also been linked to other issues. These included the desperate preoccupation with survival in difficult climatic conditions, a postcolonial legacy and the delicate balance of utilising resources without waste. What conclusions might then be drawn about the teaching of art? Utilising the work of others who have considered the issues in Kenya, this small‐scale ethnographic case study is presented with personal reflection and observations. The author would be pleased to hear from others with similar experiences or who have recognised additional issues in seemingly challenging circumstances. 相似文献

This investigation involved the surveying of school psychology practitioners (N = 291) to determine the possible existence of a relationship between administrative pressure to practice unethically and impaired occupational health, as manifested in elevated levels of burnout, job dissatisfaction, and intent to exit the workforce. Almost one‐third of participants claimed to have been pressured to behave unethically, with directives most commonly consisting of instructions to withhold recommendations for support services and to agree with inappropriate special education placement decisions. Practitioners who experienced administrative pressure reported higher levels of burnout, less satisfaction with their current position and the profession, and a greater desire to leave their job and the field of school psychology. The findings are presented within the context of current and projected shortages of practicing school psychologists. Implications for preventing burnout and promoting school psychologists’ occupational well‐being are discussed. 相似文献

This research examined varying levels of physical activity and psychomotor and physiological function in variously active older men. Very active moderately active, and low active participants were tested on simple (SRT) and choice reaction time (CRT), coincidence-anticipation timing (CAT), and VO2max. No significant differences for age or height were found, although percentage of fat, and weight were statistically different. Active groups were leaner and lighter. VO2max was significantly different between groups, as physically active groups yielded geater values. SRT and CAT also yielded significantly different results with more active participants showing better performance. No between-groups significant differences resulted for CRT. Generally, increased levels of physical activity were related to superior physiological outcomes and improved psychomotor peformance. 相似文献

This paper examines forms of boundary work undertaken by parents in a regional Australian city to negotiate social processes around the school market amidst rising economic insecurity. It outlines structural changes, which have increased economic inequality in Australia and impacted on educational reform, and the specific challenges faced by public schools in regional settings. Drawing on 18 months’ qualitative research in one regional location, it identifies and analyses forms of boundary work undertaken by middle-class families to manage these uncertainties in a field of scarce economic and cultural resources. Theories of class culture, stigma and whiteness are used to show how local social labels such as ‘ferals’ and ‘shiny people’ acted as classed and racialised ways of negotiating this social and economic landscape through the school field. Such practices engendered feelings of security and control and shed light on feelings of class-based resentment and anxiety in regional Australia, specifically a middle-class ‘fear of falling’. 相似文献

摘要:运动缺乏症(EDD)是一种儿科疾病,特点是中高强度体力活动(MVPA)下降,低于目前的推荐量,也与积极的健康结果(health outcomes)不一致。目前,大多数儿童和青少年符合EDD的诊断标准,因为他们没有达到日常MVPA的最低要求。本文的目的是强调10个与青少年EDD有关的重要研究问题。需要进行重要的研究来更好的定义EDD的临床表现,包括评估体力活动行以确定开始出现EDD的年龄或发育阶段;包括运动技巧和体能的运动起源(kinesiogenesis)的检测;以及对影响青少年MVPA的生活方式因素的评估。关于治疗EDD的干预措施和政策的研究问题,包括评估对卫生保健从业者进行运动医学重要性的教育和训练;确定在临床上识别和治疗EDD青少年的方法的有效性;开发敏感的、特效的、经济的方法以诊断青少年EDD;以及定制方法以促进本病诊疗的医疗保险赔付。如果未来研究不能优化EDD青少年的识别、治疗和管理方案,具有重大影响的生物医学、心理、经济和政治的新的卫生保健问题将会不断出现。 相似文献

Amplification of multiple unique genetic targets using the polymerase chain reaction (PCR) is commonly required in molecular biology laboratories. Such reactions are typically performed either serially or by multiplex PCR. Serial reactions are time consuming, and multiplex PCR, while powerful and widely used, can be prone to amplification bias, PCR drift, and primer-primer interactions. We present a new thermocycling method, termed thermal multiplexing, in which a single heat source is uniformly distributed and selectively modulated for independent temperature control of an array of PCR reactions. Thermal multiplexing allows amplification of multiple targets simultaneously—each reaction segregated and performed at optimal conditions. We demonstrate the method using a microfluidic system consisting of an infrared laser thermocycler, a polymer microchip featuring 1 μl, oil-encapsulated reactions, and closed-loop pulse-width modulation control. Heat transfer modeling is used to characterize thermal performance limitations of the system. We validate the model and perform two reactions simultaneously with widely varying annealing temperatures (48 °C and 68 °C), demonstrating excellent amplification. In addition, to demonstrate microfluidic infrared PCR using clinical specimens, we successfully amplified and detected both influenza A and B from human nasopharyngeal swabs. Thermal multiplexing is scalable and applicable to challenges such as pathogen detection where patients presenting non-specific symptoms need to be efficiently screened across a viral or bacterial panel. 相似文献
