关于高职院校财务管理存在的问题与对策思考

高职院校财务管理涉及高校管理的各个方面各个环节,发挥着越来越重要的作用。目前高职院校财务管理在管理理念、管理机制、人员素质等方面存在不足,财务管理存在弊端与漏洞。提高人员素质,健全管理机制,加强固定资产管理、预算管理,对提高高职院校财务管理水平具有十分重要的意义。     

Computerized Presentation of Text: Effects on Children’s Reading of Informational Material

This study examined whether children’s reading rate, comprehension, and recall are affected by computer presentation of text. Participants were 60 grade five students, who each read two expository texts, one in a traditional print format and the other from a computer monitor, which used a common scrolling text interface. After reading each text, participants were asked to recall as much as they could from what they had read and then answered questions that measured text recall and comprehension. Children took more time to read the passage and recalled more of the text material that they had read from the computer monitor. The benefit of computer presentation disappeared when efficiency variables, which take time into account, were examined. Children were, however, more efficient at comprehending text when reading from paper. The results suggest that children may take more time to read text on computer screens and that they are more efficient when reading text on paper.     

昆明产业结构的现状分析及调整对策的思考

昆明产业结构现状呈现3种转换态势,即全面发展态势,重点以第三产业为主的商贸旅游业发展态势和新型工业加速、第三产业处于稳步发展态势。昆明产业发展有4大特点：1．产业结构逐步调整优化,三次产业比例趋于合理;2．新型工业化得到大力推进,推进城市化水平显著提高;3,服务型经济持续扩张,成为未来产业发展的方向;4．现代物流业已初具规模。但昆明产业中粗放型农业仍未改变,其工业产品结构和技术水平还较低,而服务业仍处于不成熟期。为此,应采取发展高端产业、创新体制、合理布局、改善生态环境和注重人才资源培养等方面的对应措施。     

Day-level sedentary pattern estimates derived from hip-worn accelerometer cut-points in 8–12-year-olds: Do they reflect postural transitions?

Improving sedentary measurement is critical to understanding sedentary-health associations in youth. This study assessed agreement between the thigh-worn activPAL and commonly used hip-worn ActiGraph accelerometer methods for assessing sedentary patterns in children. Both devices were worn by 8–12-year-olds (N = 195) for 4.6 ± 1.9 days. Two ActiGraph cut-points were applied to two epoch durations: ≤25 counts (c)/15 s, ≤75c/15s, ≤100c/60s, and ≤300c/60s. Bias, mean absolute deviation (MAD), and intraclass correlation coefficients (ICCs) tested agreement between devices for total sedentary time and 11 sedentary pattern variables (usual bout duration, sedentary time accumulated in various bout durations, breaks/day, break rate, and alpha). For most sedentary pattern variables, ActiGraph 25c/15s, 75c/15s, and 100c/60s had poor ICCs, with bias and MAD >20%. ActiGraph 300c/60s had a better agreement than the other cut-points, but all ICCs were <0.587. ActiGraph underestimated sedentary time in longer bouts and usual bout duration, and overestimated sedentary time in shorter bouts, breaks/day, and alpha. For total sedentary time, ActiGraph 25c/15s, 300c/60s, and 75c/15s had good/fair ICCs, with bias and MAD <20%. Sedentary patterns derived from two commonly used ActiGraph cut-points did not appear to reflect postural changes. These differences between measurement devices should be considered when interpreting findings from sedentary pattern studies.     

Comparison of physiological responses to graded exercise test performance in outrigger canoeing

The aim of this study was to establish a graded exercise test protocol for determining the peak physiological responses of female outrigger canoeists. Seventeen trained female outrigger canoeists completed two outrigger ergometer graded exercise test protocols in random order: (1) 25 W power output for 2 min increasing by 7.5 W every minute until exhaustion; and (2) 25 W power output for 2 min increasing by 15 W every 2 min to exhaustion. Heart rate and power output were recorded every 15 s. Expired air was collected continuously and sampled for analysis at 15-s intervals, while blood lactate concentration was measured immediately after and 3, 5, and 7 min after exercise. The peak physiological and performance variables examined included peak oxygen uptake (VO2peak), minute ventilation, tidal volume, ventilatory thresholds 1 and 2, respiratory rate, respiratory exchange ratio, heart rate, blood lactate concentration, power output, performance time, and time to VO2peak. There were no significant differences in peak physiological responses, ventilatory thresholds or performance variables between the two graded exercise test protocols. Despite no significant differences between protocols, due to the large limits of agreement evident between protocols for the peak physiological responses, it is recommended that the same protocol be used for all comparison testing to minimize intra-individual variability of results.     

The role of science in the practice of talent identification: a case study from gymnastics in New Zealand

Abstract

Talent identification is an example of a practice where ‘scientism threatens to engulf us all.’ Talent identification and development are areas where models perceived to be scientific have been uncritically adopted into sporting practice due to the belief that they represent best practice. In this article, I track the changing talent identification systems adopted in the sport of rhythmic gymnastics in New Zealand over approximately 20 years. The findings revealed that those in decision-making positions originally adopted the perspective of scientism in introducing a physical ability test which they perceived to have scientific value. However, scientific testing was later removed owing to the now empowered gymnastics coaches drawing on what Foucault referred to as local knowledge, acquired through their own experiences. Their experiences resulted in the coaches believing in the importance of what Latour described as social practices being more significant in talent identification than scientific testing.
