为全面了解广大农民开展全民健身活动享有基本体育服务的情况，以浙、苏、皖、赣、鲁5省部分农村、农民为研究对象，采用文献资料调研、问卷调查、访问调查及逻辑分析等方法，从3个不同的层面，分别对乡镇、行政村为农民提供基本体育服务以及农民享有基本体育服务的现状进行了广泛的社会调查，并对调查结果进行了分析与研究。针对农村开展全民健身活动中存在的主要问题，提出要使广大农民享有基本的体育服务，政府需要为处于弱势地位的农村提供更多的保障，加大对村级体育扶持和帮助的力度，在人、财、物等方面优先为行政村开展全民健身活动提供必要的条件等对策与建议。  相似文献

政府部门电子政务的成熟度评估与实证研究   总被引：1，自引：0，他引：1  

樊博 《情报学报》2008,27(2):271-277

本文研究面向政府部门的电子政务成熟度评估体系.以国际电子政务成熟度模型的思路精髓为评估指标体系的总体依据,设计了该评估体系的具体指标细项,计算各级指标体系的权重,提出了成熟度评估的计算模型.进而,选择上海市的八个政府部门为实证分析的评估样本,对评估指标中的各个维度的成熟度分别进行实证数据分析,得出评估样本在每个维度的成熟度水平.然后,以八个评估样本为分析对象,计算电子政务的总体成熟度.本文的目的是利用成熟度指标体系来诊断、考核和引导政府部门电子政务的建设,推进其向健康的方向发展.  相似文献

Managing Uncertainty for Preventive Conservation     

Jane Henderson 《文物保护研究》2018,63(5):108-112

ABSTRACT

This paper examines how conservators engage with uncertainty when creating preventive conservation strategies. It argues that by recognising contexts in which uncertainty will be encountered conservators can develop effective management strategies. A typology of uncertainty explores a range of categories of uncertainty, their experience in preventive conservation and identifies distinct approaches to manage them. Managing uncertainty may include acts of defining its parameters, exposing and resolving through communication or protecting from with contingency. Whatever approach is adopted it must be accepted that uncertainty cannot be avoided. It is important therefore to aim to live well with uncertainty and the paper advocates for preventive conservation applications of strategies recommended in health care for patients with life-threatening illnesses. These strategies include working on things that can be controlled, goal setting, acceptance and factoring in emotions. The ability to identify contexts in which uncertainty is inbuilt should trigger those concerned with preventive conservation to activate strategies developed for managing and living well with uncertainty.  相似文献

Spread or Sacrifice: Dilemma for Lighting Policies     

Agnes Brokerhof  Pieter Kuiper  Steph Scholten 《文物保护研究》2018,63(5):28-34

ABSTRACT

Light sensitive objects will fade on display. Collection managers and curators face the dilemma whether to spread fading over several similar objects or sacrifice one. This paper describes an experiment in which participants were asked how they would want to pass on a collection of seventeenth century hand-coloured maps to coming generations. Results show that while colour changes are hardly visible, both public and professionals do not perceive them as damage and prefer to spread fading. Once fading becomes clearly visible in all maps, the preference shifts to sacrificing one map. The tipping point lies around five just noticeable changes. This information can be used when selecting objects for exhibition. The outcome also implies it would be prudent to assess the degree of fading of much exhibited objects and consider whether and when to choose for a sacrifice strategy.  相似文献

Walking and biologic ageing: Evidence based on NHANES telomere data     

Larry A. Tucker 《Journal of sports sciences》2020,38(9):1026-1035

ABSTRACT

The length of telomeres is an objective measure of biologic ageing. This study evaluated the extent minutes of walking per week are associated with leukocyte telomere length (LTL) in a random sample of 5,823 U.S. adults. The investigation was cross-sectional and data were obtained from the National Health and Nutrition Examination Survey (NHANES). LTL was measured by the quantitative polymerase chain reaction method. Walking minutes was calculated from walking frequency and duration measures. Results showed that for each year of chronological age, telomeres were 15.6 base pairs shorter (P < 0.0001). With walking minutes and LTL treated as continuous variables, the relationship was quadratic, not linear (F = 11.2, P = 0.0023). With walking time divided into three categories, adults who performed ≥ 150 minutes of walking per week had longer telomeres than those who did no regular walking, and those who did some, but less than the recommendation (F = 5.0, P = 0.0137). Regular walkers were estimated to have a biologic ageing advantage associated with 6.5–7.6 years less biologic ageing compared to non-walkers, after adjusting for covariates. Additional investigations designed to study causality and the mechanisms associated with the walking and LTL relationship are needed.  相似文献   

Precision measurement of the Newtonian gravitational constant     

Chao Xue  Jian-Ping Liu  Qing Li  Jun-Fei Wu  Shan-Qing Yang  Qi Liu  Cheng-Gang Shao  Liang-Cheng Tu  Zhong-Kun Hu  Jun Luo 《国家科学评论(英文版)》2020,7(12):1803

The Newtonian gravitational constant G, which is one of the most important fundamental physical constants in nature, plays a significant role in the fields of theoretical physics, geophysics, astrophysics and astronomy. Although G was the first physical constant to be introduced in the history of science, it is considered to be one of the most difficult to measure accurately so far. Over the past two decades, eleven precision measurements of the gravitational constant have been performed, and the latest recommended value for G published by the Committee on Data for Science and Technology (CODATA) is (6.674 08 ± 0.000 31) × 10⁻¹¹ m³ kg⁻¹ s⁻² with a relative uncertainty of 47 parts per million. This uncertainty is the smallest compared with previous CODATA recommended values of G; however, it remains a relatively large uncertainty among other fundamental physical constants. In this paper we briefly review the history of the G measurement, and introduce eleven values of G adopted in CODATA 2014 after 2000 and our latest two values published in 2018 using two independent methods.  相似文献
