面向全民抗疫记忆构建的疫情防控档案专题数据库建设研究

新冠肺炎肆虐,疫情期间形成了丰富的档案资料,疫情防控档案分散和类型多元化等特点显著,疫情防控档案的整合对于助力应急管理、助力医疗一线和稳定公众情绪等方面具有重要意义。基于此,文章梳理了疫情防控档案专题数据库建设目的与思路,探讨了数据库规划与设计、系统架构等内容。疫情防控档案专题数据库的建立,可为今后疫情预防与防治工作奠定基础,在应对重大突发公共卫生事件时发挥借鉴与参考作用。     

口述档案研究的可视化分析

本文通过对国内外口述档案研究的对比分析,可以了解国内外相关研究的差距之处,并且可以根据研究热点的变化,在一定程度上推测出国内外今后的研究方向和趋势。以中国知网(CNKI)和Web of Science为数据来源,基于Citespace软件,从年代分布、作者、发文机构、关键词等角度对国内外口述档案的研究进行分析。通过分析发现,在总体发文量上,国内关于口述档案的研究要低于国外,作者之间和机构之间的合作程度也是同样趋势。此外,国内外在口述档案领域的热点主要集中于口述档案与社会记忆相结合。因此,围绕"记忆、社会记忆"开展的口述档案研究可能是国内外共同的发展趋势。     

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.

基于模糊线性规划模型的水-土-作物系统优化配置研究

为了进一步对陕西省蒲东灌区农业的规划发展,本文将线性规划模型和模糊优化模型应用到灌区土地-水-作物系统的规划和管理之中。该模型用于优化经济效益、作物产量和劳动力的利用,并寻求相关作物种植模式和对土地,水,肥和劳动力利用下农业系统的优化配置。根据研究区域情况,决定采用线性规划模型的三个目标函数输出数据作为模糊规划模型的约束条件,在模糊目标和模糊约束的模糊环境下,取得模糊优化模型的最优解方案。这些非结构化的模型能够很好的将地表水资源和地下水资源有效地联合利用。此外,对灌区农业系统优化配置后的净效益进行了对比评价。结果表明,本文提出的多目标模糊线性规划管理模型应用到农业系统土地-水-作物的优化配置中是可行的,合理地分配土地和水资源,提高了作物产量和净效益。     

运动疲劳对大鼠海马CAI 区神经元电活动的影响

目的：通过神经电生理学的方法,揭示运动性中枢疲劳的神经生物学机制。方法：30只健康雄性sD大鼠,随机分为安静对照组（CG）、有氧运动组（AG）和运动疲劳组（FG）。采用微电极技术在体观察运动训练后大鼠海马CAI区神经元自发及诱发电活动的变化规律,并通过被动回避行为条件反射的方法观察大鼠的学习记忆能力。结果：FG组大鼠海马神经元的自发和诱发电活动均显著低于CG组和AG组（P〈0.05）。FG组学习记忆能力显著低于CG和AG（P〈0.05,P〈0.01）。结论：运动疲劳可抑制大鼠海马神经元的兴奋性,并降低其学习记忆能力。提示：海马神经元自发放电频率与学习记忆能力有密切关系,运动疲劳导致海马神经元电活动的变化可能是其学习记忆能力降低的机制之一。

影响少年速滑运动员比赛成绩相关心理因素分析

少年速滑运动员由于正处在特殊的年龄阶段,其心理发展的速度往往滞后于生理的发展,加上比赛中激烈的竞争刺激,必然会导致由于心理因素而产生影响比赛成绩的现象。通过心理问卷法、文献分析法、调查访问法和数理统计法,对影响少年速滑运动员比赛成绩相关心理因素的类型、特点和原因进行了分析,结果表明自我效能感、焦虑、情绪记忆、场依存性是影响比赛成绩的重要心理因素,男运动员和女运动员在情绪记忆和自我效能感方面存在显著差异。     

Culture without “world”: Australian cultural policy in the age of stupid

In March 2013, after six years of consultation, an Australian Labor government launched the national cultural policy document, Creative Australia. In July 2013, a Coalition government was elected, Senator George Brandis became Minister for the Arts, and the policy was dumped. With it went cross-party consensus about funding rationales and measurement strategies, with disastrous consequences for the cultural sector. This cautionary tale of gaffes, pay-back and abrupt changes of direction, highlights the fragility of policy memory that condemns artists and arts managers to a never-ending reinvention of the evidentiary wheel. Our paper examines the problem of collective understanding (“world”) in cultural policy-making in Australia, exacerbated not only by the short-term electoral cycles which undermine long-term cultural outcome timescales, but by a fixation on what Hannah Arendt calls “the peculiar and ingenious replacement of common sense with strict logicality”. Evidence of value is only meaningful when it occurs in a policy memory that can fully avow it and respond in appropriate ways. Measurement methods are over-determined by epistemology and by experience. We argue that the balance between these determinants of effective cultural policy-making has been lost. An emphasis on numerical data – especially economic data – has forced arguments for culture into a decontextualised register of quantitative proof. Recent events in Australia suggest that different, more direct ways of engaging with cultural policy-making are required for the problem of collective understanding to be successfully assayed.     

A lonely and beautiful country: reflecting upon the state of oblivion in Turkey through Nuri Bilge Ceylan's Three Monkeys

Abstract

Through an in‐depth analysis of internationally acclaimed Turkish director Nuri Bilge Ceylan's 2008 film Three Monkeys (Üç Maymun), this article discusses the politics of Ceylan's cinema against the backdrop of the current memory debate in Turkey. Turkey has a troubling relationship with its past. The process of the foundation and the early development of the Turkish nation‐state included traumatic events during which ethnic and religious minorities were massacred, deported, or encouraged to migrate. There have also been several violent incidents in Turkey's subsequent history that include massacres, mass killings, political assassinations, as well as military coups. It is a widely held opinion that social memory in Turkey is based on forgetting and denial, that is, Turkish society deals with the troubling events in its past by turning a blind eye to them. Drawing upon the question of how it may be possible to make the traces of forgetting and silence observable, this paper argues that Ceylan's film, despite its seemingly apolitical story, has indeed profound political connotations since its narrative and visual organization serve to display the prevailing mood of silence, oblivion and complicity in Turkey.
