熔岩管冷却过程中的热应力计算

除本身造成的直接灾害外,火山喷发的基性熔岩流动过程中经常会形成熔岩管.由于地下空洞的存在,熔岩管附近区域的地表稳定性会降低,容易发生坍塌,造成次生灾害。月球和火星上发现的熔岩管是未来外星探测基地的最佳选择,对于熔岩管稳定性研究也具有潜在价值。本文运用有限元方法,基于熔岩管形成机制,建立熔岩管形成后温度演化过程和相应的位移和热应力状况.通过分析熔岩管附近主应力的演化过程,考察不同物理参数(熔岩管的大小、深度、形状)对于熔岩管稳定性的影响。     

利用矿物流变性质对面理岩石流变性质的有限元方法计算

高温高压下岩石表现出流变性质。流变参数是数值模拟地球动力过程必需的重要参数。获得流变参数需要借助于室内的高温高压蠕变实验以及野外的地球物理资料观测的反演。对单矿物的高温高压实验比较多,多矿物组成的岩石的实验则较难较少。本文探讨在单矿物流变参数已知的条件下,能否运用有限元法,计算多矿物岩石整体的流变参数。研究表明,计算结果与高温高压实验获得的参数可以对应。即使矿物力学性质可以近似为各向同性时,如果矿物排列有优势方向（例如存在面理的花岗质糜棱岩）,计算表明岩石整体会显示各向异性。当加载外力与矿物面理方向垂直或平行时,岩石的等效黏滞系数较大;当所成角度为30°左右时,等效黏滞系数最小。     

武术大负荷训练对民族传统体育大学生血乳酸和血尿素氮影响的研究

观察15名民族传统体育专业大学生在武术大负荷训练前后血乳酸和血尿素氮的变化,分析血乳酸和血尿素氮与民族传统体育大学生训练水平的关系,结果表明：血乳酸和血尿素氮能够客观评定训练强度,为科学训练提供依据;大运动负荷训练对学生血乳酸和血尿素氮变化有不同程度的影响,但存在个体差异。

大学生运动行为与其相关因素分析——以福建农林大学为例

通过问卷调查的形式,采用统计、计量分析方法,深入分析影响大学生运动行为的社会经济因素及社会心理因素之间的定量关系。结果显示,52％的学生表示自己有运动习惯,但是真正符合美国运动医学会（ACSM）推荐的规律运动标准的仅34．2％;其中男生有规律运动者占21．5％,女生仅为12．7％;低年级规律运动的比例高于高年级。通过logistic回归可以预测全体受访者是否规律运动的因素包括：性别、年级、体育测试压力、母亲受教育的程度和可利用的时间是否充足。研究提示,大学生规律运动比例较低,社会经济状况和社会心理因素会对其规律运动行为造成影响,因此针对影响规律运动的因素制定其相应的对策尤为重要。     

我国职业运动员人力资本产权交易制度研究

为了完善我国职业运动员人力资本产权交易制度,该研究以人力资本理论、产权理论、微观经济学、新制度经济学、法学理论为研究基础,结合我国职业体育实践以及国外职业体育的成功经验,对我国职业运动员人力资本要素市场存在的问题进行研究,认为我国职业运动员人力资本产权交易制度中存在的主要问题在于：稀缺性运动员人力资本的供需关系矛盾突出;职业运动员人力资本要素市场不完善,买方垄断、卖方垄断的运动员人力资本要素市场并存;运动员人力资本投资专用性治理措施不合理。我国职业运动员人力资本产权交易制度改革的近期目标,要围绕明确职业运动员劳动者的地位,保护职业运动员合理的自由选择权与自由流动权,采取有效措施增加优秀运动员人力资本的供给,采取有效措施限制职业体育俱乐部的过度竞争行为,设立职业运动员最低薪酬标准,保护普通职业运动员的权益等方面进行。     

People's security: Okinawa's anti-bases movement

Abstract

The evolution of moral panics is dependent on the particular social context and the ability of certain issues to trigger concern within society. In this paper, the authors have employed a cross‐comparative study of the heavy metal music subcultures in Singapore and Malaysia to understand the differences in the issues that generate such panics based on the socio‐political context of each country and its current concerns. Although the youth involved in both cases are marginalised male Malays, the framing of their alleged deviance and criminality permits, in the case of Singapore, only a limited possibility for moral panic creation given the conservative socio‐political governance that limits allegations such as ‘Satanism’. In the case of Malaysia, where a ‘large‐scale’ moral panic involving black metal emerged in 2001, the recent trend towards Islamisation gave fodder for the condemnation of black metal based on the allegations of the anti‐Islamic behaviour of Muslim youth involved in the black metal scene. In both cases, such groups were exploited by parties claiming to defend the social fabric of the moral majority, but in the latter case it took on grave implications due to the extent of the state and public response. This paper thus argues that the framing of these moral panics is an important component determining the relative ‘success’ of the panic or its ability to capture public and state imaginings.     

《鬼妈妈》恐怖元素与作用探析

随着制作观念的开放,新的青少年儿童文艺形式不断衍生,融入了恐怖元素的作品大量涌现,影片《鬼妈妈》就是一部成功之作。儿童片与恐怖因素并非势不两立,合理适度的运用恐怖因素有利于激发青少年儿童的想象力,培养他们分辨是非的能力和勇于挑战的精神。少儿文艺影视作品的恐怖元素也会对青少年儿童带来不良影响,在其应用于儿童片时应以禁止滥用、避免危害少年儿童为原则。     

The Effect of Bilingualism on the Measured Intelligence of Elementary School Children of Italian Parentage

The recency of the community college movement has prevented large scale organization and dissemination of knowledge concerning the processes and steps required to establish a community college. There is, therefore, a need for means to incorporate contemporary evidence into the curriculum of prospective administrators of higher education. The purpose of this study was to compare Higher Education Administration students’ peceptions of a logical sequence of events for establishing a community college with a sequence of events for establishing a community college as determined by practice. The Edwards’ matched-pair technique was used to rank the perceptions of the students. A sequence of twenty-nine events was selected from the literature. Each event was matched with every other, thus providing 406 decision situations. From these decisions an ordering was obtained. Using the Spearman rho correlation technique, a coefficient of 0.82 was found between the sequence of events taken from the literature and rank ordering of these events as determined by the Edwards’ matched-pair technique.
