CBA球员球场暴力行为的归因研究与治理省思 ——基于互动仪式链视角     

买器 《河北体育学院学报》2020,34(3):37-41

运用文献资料法和逻辑分析法，以互动仪式链理论为视角，从文化资本互动与情感能量互动两方面对CBA球场暴力行为的发生机制进行研究。指出，赛前与赛中的互动仪式相互联系，赛前不良的互动仪式会将负向的情感能量带入比赛，使共享情感破裂，产生球场暴力现象。球员个体间情境互动会过渡到球队群际间，暴力行为会通过互动仪式链不断扩散到其他球队。比赛中双方都存在冲突性紧张，谁能抢占情感能量主导权谁就会在博弈中占据优势地位，处于压制的一方将转化为恐惧感。恐惧与冲突性紧张塑造了暴力情景，导致了球场暴力行为的发生。提出，应规范球员行为表现，防止球员暴力惯习的形成；加强球队球员间的沟通交流，修复断裂的互动仪式链条；注重裁判执裁能力建设，维持现场球队双方情感能量的平衡；营造有序的观赛环境，激发球迷潜在的道德情感。旨在为CBA健康有序发展提供建议与参考。  相似文献   

双积分制下的新能源汽车产业链续航能力决策研究     

马亮  郭鹏辉 《科技管理研究》2019,(23)

在双积分制背景下，通过构建产业链自制式决策和外购式决策模型，研究了新能源汽车产业链中乘用车生产企业和电池生产企业的最优决策问题。结果表明：消费者支付意愿的提高、电池生产企业的研发能力的提升、市场上新能源汽车积分交易价格的上涨，都有利于两种决策产业链中新能源汽车续航能力的提高；自制式决策更有效，但外购式决策产业链可以通过提升消费者支付意愿、提高电池企业的研发能力来达到自制式决策产业链利润的效果。在外购式决策产业链中引入了政府补贴机制，实现产业链良性发展。在此基础上，给出了新能源汽车产业发展的建议。  相似文献

A comparison of the agreement,internal consistency,and 2-day test stability of the InBody 720, GE iDXA,and BOD POD® gold standard for assessing body composition     

Bruce W Bailey  Gabrielle LeCheminant  Timothy Hope  Mathew Bell  Larry A Tucker 《Measurement in physical education and exercise science》2018,22(3):231-238

The study compared the agreement, internal consistency, and measurement stability of the GE iDXA, BOD POD, and InBody 720. Body composition of 43 men and 37 women (31.4 ± 10.7 years; 90% Caucasian and 10% other) was assessed in triplicate using each method over two different days. Mean percent body fat (% BF) of the participants was different for all three machines (27.6 ± 10.0% [GE iDXA)] 25.6 ± 10.4% [BOD POD], and 21.3 ± 10.6% [InBody 720]; p < .05). The coefficient of variation for same day repeated measures was 1.06% (GE iDXA), 3.29% (BOD POD), and 2.97% (InBody 720). The coefficient of variation for 2-day repeated measures was 1.81% (GE iDXA), 4.61% (BOD POD), and 4.24% (InBody 720). The difference between the GE iDXA and BOD POD was within acceptable variability, while the InBody 720 significantly underestimated % BF. The internal consistency was highest for the GE iDXA, followed by the InBody 720, and then the BOD POD.  相似文献   

Comparative evaluation of heart rate-based monitors: Apple Watch vs Fitbit Charge HR     

Yang Bai  Paul Hibbing  Constantine Mantis  Gregory J. Welk 《Journal of sports sciences》2018,36(15):1734-1741

The purpose of this investigation was to examine the validity of energy expenditure (EE), steps, and heart rate measured with the Apple Watch 1 and Fitbit Charge HR. Thirty-nine healthy adults wore the two monitors while completing a semi-structured activity protocol consisting of 20 minutes of sedentary activity, 25 minutes of aerobic exercise, and 25 minutes of light intensity physical activity. Criterion measures were obtained from an Oxycon Mobile for EE, a pedometer for steps, and a Polar heart rate strap worn on the chest for heart rate. For estimating whole-trial EE, the mean absolute percent error (MAPE) from Fitbit Charge HR (32.9%) was more than twice that of Apple Watch 1 (15.2%). This trend was consistent for the individual conditions. Both monitors accurately assessed steps during aerobic activity (MAPE_Apple: 6.2%; MAPE_Fitbit: 9.4%) but overestimated steps in light physical activity. For heart rate, Fitbit Charge HR produced its smallest MAPE in sedentary behaviors (7.2%), followed by aerobic exercise (8.4%), and light activity (10.1%). The Apple Watch 1 had stronger validity than the Fitbit Charge HR for assessing overall EE and steps during aerobic exercise. The Fitbit Charge HR provided heart rate estimates that were statistically equivalent to Polar monitor.  相似文献

李宇  王佳  毛培培 《科研管理》2018,39(8):1-10

有利于产业创新升级的企业成长模式一直是研究热点问题。本文将我国产业创新升级普遍存在的低产业化、大而不强和传统产业升级抽象为企业规模阈值问题，并通过对三种规模阈值的突破引入和界定了企业规模质量的概念范畴。以此为基础并结合文献分析法，本文提出构成企业规模质量的R&D投入、非R&D投入和知识能量3个维度及11个能力要素，通过预测试、问卷调查等方式进一步实证检验了量表的可靠性和有效性，得出了有助于推动产业创新升级的企业规模质量量表工具。在量表工具下本文提出了针对技术创新和产业升级的对策建议。  相似文献

Energy,macronutrient and water intake during a mountain ultramarathon event: The influence of distance     

Sonia Martinez  Antoni Aguilo  Lluis Rodas  Leticia Lozano  Carlos Moreno 《Journal of sports sciences》2018,36(3):333-339

Adequate dietary strategies are essential for the successful participation in ultra-endurance races. The aim of this study was to evaluate and compare the energy and water intakes of participants during three different mountain ultra-endurance runs. The study took place at the “Ultra Mallorca Serra de Tramuntana” (Mallorca, Spain), an ultra-endurance mountain event with runners participating either in a 44-km (Marathon, n = 51), a 67-km (Trail, n = 109) or a 112-km (Ultra, n = 53) run competition. Participants in the study answered a questionnaire focused on the nutritional intake within an hour after finishing the competition. Mean energy intake during the competitions was 183 kcal · h^¯1, with an average carbohydrate intake of 31 g · h^¯1 (52.1% of participants consumed less than 30 g · h^¯1). No significant differences between competitions were found in these parameters. However, a higher percentage of energy from lipids in participants in the Trail and the Ultra was found (P = 0.034). Furthermore, significant differences were observed in water intake per hour of competition (P = 0.039), with the lowest value for the intake during the Ultra competition. In conclusion, the majority of the participants in the study present low carbohydrate intakes. However, fluid intake seems to be adequate. Different distances did not significantly influence the participants’ nutritional strategies.  相似文献   

Energy Internet forums as acceleration phase transition intermediaries     

Sampsa Hyysalo  Jouni K. Juntunen  Mari Martiskainen 《Research Policy》2018,47(5):872-885

Citizen users play important roles in the acceleration phase of energy transitions, during which small-scale renewable energy technologies (S-RET) become taken up more widely. From users’ perspective, turning the early, and typically slow, proliferation into a more rapid and widespread diffusion requires not only the adoption of S-RET but also the adaptation, adjustment, intermediation and advocacy of S-RETs. These activities become necessary because S-RET face a variety of market, institutional, cultural and environmental conditions in different countries. New Internet-based energy communities have emerged and acted as key user-side transition intermediaries that catalyse these activities by qualifying market information, articulating demand and helping citizen users to reconfigure the standard technology to meet the specificities of different local contexts. In doing so, Internet communities foster an appreciatively critical discourse on technology. Such user intermediation is important in expanding the markets for S-RET beyond that of enthusiasts, environmentalists and other early adopters, to the early majority of adopters who demand more exposure, clearer information and less uncertainty about new technology options.  相似文献
