γ辐照Al~(3+):α-石英晶体的光吸收谱及其GOW心的色心电子能态

本文用水热法生长了Al~(3+):α-SiO_2石英晶体,测量了γ射线辐照赋色的晶体的吸收光谱。主要的可见吸收带位于2、61ev,2.07ev和2.30ev处。其中2、6ev和2、07ev吸收带是GOW心(即〔Al_(e+)〕°心)产生的色心吸收带。本文理论上计算了GOW心的电子能态。对应该心两个吸收带的理论值分别位于2、72ev和1.94ev与实验结果相符。     

Time use satisfaction of wives: Home,farm, and labor force workload

Factors related to time spent in work roles are investigated for a sample of 685 wives living on family farms in seven southern and midwestern states. Data were collected in a comprehensive mail survey. Results show that variables reflecting management are the most important predictors of wife's time use satisfaction. Wife's satisfaction is also significantly related to her education and nonfarm employment. Conclusions indicate that, although wives on family farms experience work-role overload relative to their husbands, they are satisfied with their time contributions to the home/farm situation.Jeanne L.

数字经济供给使用表:概念架构与编制实践研究

数字经济供给使用表是数字经济卫星账户的核心表式,具有统计协调和分析工具的双重作用,能够准确监测数字经济产业发展规模及传统产业与数字经济的融合程度。目前,国际上对数字经济供给使用表的研究尚处于初期探索阶段,还未有国家编制出基于实际数据的数字经济供给使用表,经济合作与发展组织(OECD)对数字经济供给使用表的理论框架进行了前瞻性探索,但系统的数字经济供给使用表构建指南还亟待完善。本文首先从供给和使用层面构建数字经济供给使用表概念框架,界定数字经济特征活动的概念和范围,梳理OECD 划分的数字经济供给使用表中的产品清单和数字经济产业分类;阐释数字经济最终消费、固定资本形成、贸易活动的内涵和种类。其次,围绕“产品×产业×特征活动”三重维度,设计数字经济供给使用表整体架构、阐明其核心指标。再次,编制数字经济供给使用表实例,剖析编制流程、总结编制要点。最后,提出结论和建议。本文尝试完善数字经济统计核算体系,为提出促进我国数字经济高质量发展的政策建议提供核算方法参考。     

关于建立数字作品使用及保护体系的研究

2 1世纪 ,数字技术的运用正在逐步地得到扩展 ,数字作品是数字技术最主要的技术成果 ,它对知识产权制度 ,尤其是版权制度提出了前所未有的挑战。文章首先介绍了数字作品的版权规范 ,主要集中于复制权及传输行为 ;其次 ,阐述构建数字作品的特殊保护机制     

网络使用、网络依赖与网络信息可信度之相关性研究

借助于“媒介可信度理论”与“媒介系统依赖理论”,采用问卷调查方法,我们探讨了网民对于网络信息的可信度评价,及网民对于网络的使用行为与其对网络的心理依赖间的关系。研究发现,网民的网络使用和网络依赖显著相关;网民的网络使用时间、网络使用经验、网络依赖及其人口变量与网络信息的可信度皆显著相关;网民在网络上不同类型的信息之间,其可信度评价存在显著差异。     

Implementing Rigorous Survey Methodology within Contexts of Social Work Education,Training and Practice: A Case Study in Substance Use

With the integration of evidence-based practice central to all areas of social work education and training across the globe, it is crucial that we continue to engage with the methodological challenges inherent in gathering this evidence, particularly when it is related to the nature of social work education itself. As a result, this paper addresses some of the methodological challenges involved in examining the education available to social workers on engaging with substance use, both within the social work academy and local authorities in England. Drawing on experiences of implementing large scale online surveys from three substantial research projects completed by the authors, this paper highlights four methodological themes: (1) Constructing a representative sampling frame; (2) Identifying participants within organisations with many departments; (3) Response rates; and (4) Questionnaire design. While these are familiar methodological considerations, this article draws attention to the specific complexities of gathering ‘representative’ knowledge to inform educational strategies on substance use within social work education and employment contexts. Finally this paper offers lessons learned and guidance for social work academics, students and practitioners who are minded to build, or draw from, an evidence-base using representative samples from and within these environments.     

空间格义背后的举意与旁观——《日用家当》中“家宅”的心理几何图解

在爱丽丝·沃克的短篇小说《日用家当》中,家宅被赋予了一定的格义属性,这可以被视为19世纪女性主义文学批评语境中的心理现象学介入。家宅格义背后的心理图解划清了个体＂生存空间＂的原型与流变,洋溢着深切的心理几何假设内涵。作者借助不同人物对于家宅的写实性解读,提供了一个富有曲面内涵的边缘记忆空间,揭示了主体的物我元一思想已然深植于家宅意象当中,并以拓扑图腾的同胚形式得以彰显。家宅的心理几何图解立体地刻画了个体在生存空间日渐缩限时的困顿与挣扎,更是直指个体守护本我世界时的一种精神重估,而这正是该部文学作品所隐含的原生代性旨归所在。     

浅谈《青史演义》对儒家思想的吸收与借鉴

《青史演义》是尹湛纳希的代表作,开蒙古族长篇小说之先河。作者在本民族文化土壤上大量吸收和借鉴汉族传统文化,特别是吸收和借鉴儒家思想,以儒家的"礼"来规范13世纪的蒙古族社会;以"孝悌"、"信义"等思想来规范当时人际关系;受君权神授思想的影响,神化真龙天子意象,形成神圣和谐的宫廷龙凤意象。这不仅显示作家的时代理想,同时也促进了蒙汉文化交流的发展进程。     

浅谈我国婚姻法探望权的执行

在我国司法界中探望权的执行存在着一定的难度。由于探望权执行表现为一种需要长期反复的行为,其执行的对象又是特定的相对人,并且需要多方配合才能实现,这就增加了执行的难度。要完善这一立法,应从其性质入手,深入分析在执行中遇到的问题及相应的解决方法,并借鉴他国经验,从而完善我国探望权的执行。     

不同体系下亚甲蓝聚合状态的光谱研究

应用吸收光谱法研究了亚甲蓝在不同浓度时以及添加不同浓度十二烷基硫酸钠时的聚合状态的变化,探讨了亚甲蓝与十二烷基硫酸钠之间相互作用机理,同时考察了乙醇、NaCl、羟丙基-β-环糊精以及Triton X-100对亚甲蓝聚合状态的影响。结果表明亚甲蓝溶液浓度和溶剂对亚甲蓝的聚合状态都有影响。
