Er^3＋：Y0.5Gd0.5VO4晶体生长和缺陷研究

采用液相法合成了多晶材料,用高温提拉法（CZ法）生长出Er^3＋：Y0.5Gd0.5VO4晶体。用ICP光谱法测定晶体中Er^3＋离子含量为1．25at％,分凝系数为1．06。采用热磷酸腐蚀晶片,在偏光显微镜下对晶体的（010）、（001）面上的缺陷进行了观察,可明显观察到位错线、生长层和包裹物。南此得出,Er^3＋：Y0.5Gd0.5VO4晶体的主要缺陷是位锚、生长层和包裹物等。

Latent Variable Modeling and Adaptive Testing for Experimental Cognitive Psychopathology Research

The adaptation of experimental cognitive tasks into measures that can be used to quantify neurocognitive outcomes in translational studies and clinical trials has become a key component of the strategy to address psychiatric and neurological disorders. Unfortunately, while most experimental cognitive tests have strong theoretical bases, they can have poor psychometric properties, leaving them vulnerable to measurement challenges that undermine their use in applied settings. Item response theory–based computerized adaptive testing has been proposed as a solution but has been limited in experimental and translational research due to its large sample requirements. We present a generalized latent variable model that, when combined with strong parametric assumptions based on mathematical cognitive models, permits the use of adaptive testing without large samples or the need to precalibrate item parameters. The approach is demonstrated using data from a common measure of working memory—the N-back task—collected across a diverse sample of participants. After evaluating dimensionality and model fit, we conducted a simulation study to compare adaptive versus nonadaptive testing. Computerized adaptive testing either made the task 36% more efficient or score estimates 23% more precise, when compared to nonadaptive testing. This proof-of-concept study demonstrates that latent variable modeling and adaptive testing can be used in experimental cognitive testing even with relatively small samples. Adaptive testing has the potential to improve the impact and replicability of findings from translational studies and clinical trials that use experimental cognitive tasks as outcome measures.

首先对ISC、SCSN与CRN地震目录进行地方时转换 ,并进行序列统计 ,建立了地方时地震时间频度分布 ,然后对地震地方时序列做了频谱分析 ,以提取地震序列中的特征周期成分 .地方时统计结果显示 :( 1 )地震频度在地方时 9时和 1 9时附近最低 ,0时和 1 3时附近最高 ;( 2 )存在以 1 2h和 2 4h为主的周期 ;( 3)较大地震和小地震有不同的活动规律 .频谱分析的结果表明 ,ISC、SCSN与CRN地震地方时序列除了存在 1 2h、2 4h等特征周期对应日潮和半日潮之外 ,还存在 1 1 7a、1a与 1 7 5a等的周期 ,分别对应太阳黑子的活动周期、地球公转及接近对应月球升交点的回归年 .     

Beyond Interests, Ideas, and Technology: An Institutional Approach to Communication and Information Policy

This article examines the theoretical assumptions generally used in communication and information policy studies, and suggests that more attention to the institutional determinants of public policies is needed. The first part discusses three alternative theoretical approaches: the interest-group approach, the ideological approach, and the technology-centered approach. The second part outlines the conceptual tools of the new institutionalism approach and discusses its application for the study of regime change in telecoms and media. The third part presents an abbreviated example of such application to the case of U.S. spectrum policies and the licensing of digital broadcasting. The conclusion suggests new directions for research aimed at broadening the set of social actors participating in the global governance of new technologies.
