文化多元化视域下马克思主义大众化及其实践路径

文化多元化是当前我国马克思主义意识形态文化建设的基本文化生态。文化多元化在对人类文明进步产生巨大推动作用的同时,也对马克思主义主导意识形态文化建设带来了消极影响和认同危机。面对文化多元化负效应的影响,加快推进马克思主义大众化,就要坚持社会主义核心价值体系的引领,坚持主流文化的主导,正确对待传统文化的继承与弘扬,善于学习和借鉴人类文明的共同成果,同时坚持党领导下的理论创新等。

The effects of a calf pump device on second half performance of a simulated soccer match in competitive youth players

During soccer matches, performance decrements have been reported that relate to both physical abilities and technical skills. To investigate the effects of low-frequency electrical stimulation LFES (VeinoplusSport®, Ad Rem Technology, France) administered during half-time recovery on performance alterations during the second half. Twenty-two highly trained young players undertook a soccer-match simulation (SAFT⁹⁰). During half-time, they were randomly assigned to LFES group or Placebo group. Each half was split into 3 bouts of 12 minutes. Following each bout, maximal strike speed (MSS), sprint test (ST), maximal sprint accelerations (MA) and metabolic power (MP) were determined in both groups. Arterial (AF) and venous flows (VF) were measured at rest and at the end of half-time. LEFS group exhibited beneficial effects on performance compared to the Placebo group with a likely effect for MSS, ST, MA, and a possible effect for MP. AF and VF increased statistically more in LEFS group compared to Placebo group. The use of specific calf-pump LFES during half-time of a youth simulated soccer match attenuated the decrease in performance during the second half compared to Placebo group. This effect is most marked at the beginning of the second half with regards to explosive parameters.     

Evening electronic device use and sleep patterns in athletes

The present study aimed to investigate pre-sleep behaviours (including evening electronic device use) and sleep quantity in well-trained athletes. Seventy well-trained athletes (44 females, 26 males) aged 21 ± 4 y from a range of team and individual sports were asked to complete an online sleep diary for 7 days. The sleep diary included questions about pre-sleep behaviours (e.g. napping, caffeine intake), electronic device use in the 2 h prior to bedtime (e.g. type of device and duration of use) and sleep (e.g. time in bed, sleep onset latency). On average, athletes spent 8:20 ± 1:21 h in bed each night. Associations between age, time in bed and sleepiness suggested that younger athletes spent more time in bed (B = -0.05, p = 0.001) but felt sleepier (r = -0.32, p < 0.01) than older athletes. On average, athletes mostly used electronic devices for 0–30 min prior to sleep. The use of multiple devices in the evening was associated with more perceived difficulty in falling asleep (B = 0.22, p = 0.03), but no associations existed with other sleep variables. In summary, younger athletes may require later start times or improved sleep quality to resolve excessive sleepiness.     

1953年粮食危机与统购统销政策的出台

统购统销政策的出台,与1953年粮食危机的出现、过渡时期总路线的贯彻有密切的关联。此前,中国粮食供需的总体形势虽有所缓和,但并没有根本好转。为解决大规模工业化建设对粮食的需求以及稳定物价的需要,中央政府不得不谋求新的控制粮食资源的办法。粮食危机的出现,为统购统销政策的出台提供了一个重要时机。另外,在酝酿采取统购统销政策时,中央政府一开始就把它纳入到过渡时期总路线中去,以便对城乡传统生产关系进行改造。
