论创新观念的实现机制

实践的辨证本性是创新观念产生发展的动力机制；理性因素和直觉、非理性因素构成了创新观念运行的思维机制；合规律性合目的性是创新观念转化的内在约束机制；而社会的经济条件、政治条件、精神条件则是创新观念实现的外部环境机制。     

地籍测量综合实习中新技术应用研究

地籍测量成果一经土地登记即具有法律效力,直接关系着国家与私人土地产权的归属问题,因此,只有采取先进、精确的测量仪器与方法,才可以保证地籍测量最终成果的合理、准确、适时。本文认为,地籍测量实践教学可以通过转变实习指导思想,合理安排实习内容,创造必要的软、硬件条件,从而有效的引入GPS、RS、GIS等新技术,使学生了解并认识新技术,更重要的是学会如何运用新技术解决地籍测量中的实际问题。     

新课程标准与小学古诗教学

小学语文新课程标准的颁布和语文教学理论研究的发展,要求古诗教学体现其新理念和新方法,从具体感知、激活想象、触发情感等三方面入手,正确把握语文教学乃至古诗教学的特点.     

新时代非典型用工关系的定位与规制

随着中国进入特色社会主义新时代和市场经济的深化,在劳动用工领域出现了一些用工灵活、从属性降低的非典型用工关系。这类用工关系法律关系性质模糊,法律规制缺乏。从非典型用工关系的内涵以及与劳务关系的区别看,其性质还是应该界定为劳动关系。为解决其规制问题,立法者需要在了解我国国情的基础上,借鉴域外规制的做法和经验。首先,采取将非典型用工关系纳入劳动法域调整的规制路径。其次,用劳动基本法规制涉及特殊用工方式、特殊用工主体的非典型用工关系,对涉及不同行业、领域的非典型用工关系则通过制定单行法规进行调整,从而最终形成中国特色的社会主义法治体系。     

手工教学策略新探

当今,虽然对于"创造教育"的研究早已成为不"时尚"的课题,人们对此也做过许多有关方面的探索研究,但倘若我们冷静反思当前高职高专学院美术学科手工课程教学的现状,便会发现其教学策略仍然停滞在长期以来一直沿用的在"继承"的基础上谈"设计"的模式上,仍存在着对"创造"内涵认识的浅表化及创造技术的单一化。我们只有以宏观的角度、全新的现代"创造学"科学理论重新审视与指导"创造教育,"把教育目标锁定在引导学生自主研究如何对传统项目进行全方位的"技术革新"上,把培养学生的开拓创新能力摆在第一位,才能真正从实质上实现拓宽学生的思路,全方位激发其创造灵感,使其思维更富有创见性。     

Inter-participant variability in daily physical activity and sedentary time among male youth sport footballers: independent associations with indicators of adiposity and cardiorespiratory fitness

Participation in youth sport is assumed to promote and contribute towards more physically active lifestyles among children and adolescents. The aim of this study was to examine inter-participant variability in objectively measured habitual physical activity (PA) behaviours and sedentary time among youth sport participants and their implications for health. One-hundred-and-eighteen male youth sport footballers (Mean ± s = 11.72 ± 1.60) wore a GT3X accelerometer for 7 days. Average daily PA [min · day^?1, in light (LPA), moderate (MPA), vigorous (VPA) and combined moderate-to-vigorous (MVPA)] and sedentary time were calculated. Participants’ body mass index adjusted for age and sex (BMI–standard deviation score), per cent body fat (BF%), waist circumference and cardiorespiratory fitness were assessed. Results revealed that variability in daily PA behaviours and sedentary time (min · day^?1) was associated with BMI–standard deviation score [VPA (?), MVPA (?)], BF% [sedentary time (+), VPA (?), MVPA (?)], waist circumference [sedentary time (+), LPA (?)] and cardiorespiratory fitness [sedentary time (?), MPA (+), VPA (+), MVPA (+)]. Whilst sedentary time and MVPA were not related to health outcomes independent of one another, associations with markers of adiposity and cardiorespiratory fitness were stronger for sedentary time. Sedentary time was also significantly positively related to waist circumference independent of VPA. Results demonstrate inter-participant variability in habitual PA and sedentary time among youth sport participants which holds implications for their health. Thus, promoting PA and, in particular, reducing sedentary time may contribute towards the prevention of adverse health consequences associated with a physically inactive lifestyle for children and adolescents active in the youth sport context.     

Accelerometer data requirements for reliable estimation of habitual physical activity and sedentary time of children during the early years - a worked example following a stepped approach

This study presents a worked example of a stepped process to reliably estimate the habitual physical activity and sedentary time of a sample of young children. A total of 299 children (2.9 ± 0.6 years) were recruited. Outcome variables were daily minutes of total physical activity, sedentary time, moderate to vigorous physical activity and proportional values of each variable. In total, 282 (94%) provided 3 h of accelerometer data on ≥1 day and were included in a 6-step process: Step-1: determine minimum wear-time; Step-2: process 7-day-data; Step-3: determine the inclusion of a weekend day; Step-4: examine day-to-day variability; Step-5: calculate single day intraclass correlation (ICC) (2,1); Step-6: calculate number of days required to reach reliability. Following the process the results were, Step-1: 6 h was estimated as minimum wear-time of a standard day. Step-2: 98 (32%) children had ≥6 h wear on 7 days. Step-3: no differences were found between weekdays and weekend days (P ≥ 0.05). Step-4: no differences were found between day-to-day variability (P ≥ 0.05). Step-5: single day ICC’s (2,1) ranged from 0.48 (total physical activity and sedentary time) to 0.53 (proportion of moderate to vigorous physical activity). Step-6: to reach reliability (ICC = 0.7), 3 days were required for all outcomes. In conclusion following a 7 day wear protocol, ≥6 h on any 3 days was found to have acceptable reliability. The stepped-process offers researchers a method to derive sample-specific wear-time criterion.

9.11事件后地缘政治观的反思

地缘政治这一传统观念在经济全球化、政治趋向多极化的背景下,遇到了强有力的挑战。9.11事件后美国政府正在重构其地缘逻辑思维。适时提出“时缘政治”和“人缘政治”概念,全面审视世界政治格局。我国应从国家利益出发,积极重构地缘战略格局。
