天津左翼文学期刊的文献学考察

创办于20世纪二、三十年代的天津左翼文学期刊,是天津左翼文学的主要阵地,但迄今为止缺乏有效的发掘和整理。本文意在通过对《星星》、《夜鹰》、《南中学生》、《当代文学》等十余种天津左翼文学期刊的梳理与论述,总结其文献学价值,为更为系统的天津左翼文学研究提供文献学的支持。     

NCME 2008 Presidential Address: The Impact of Anchor Test Configuration on Student Proficiency Rates

Examined in this study were the effects of reducing anchor test length on student proficiency rates for 12 multiple‐choice tests administered in an annual, large‐scale, high‐stakes assessment. The anchor tests contained 15 items, 10 items, or five items. Five content representative samples of items were drawn at each anchor test length from a small universe of items in order to investigate the stability of equating results over anchor test samples. The operational tests were calibrated using the one‐parameter model and equated using the mean b‐value method. The findings indicated that student proficiency rates could display important variability over anchor test samples when 15 anchor items were used. Notable increases in this variability were found for some tests when shorter anchor tests were used. For these tests, some of the anchor items had parameters that changed somewhat in relative difficulty from one year to the next. It is recommended that anchor sets with more than 15 items be used to mitigate the instability in equating results due to anchor item sampling. Also, the optimal allocation method of stratified sampling should be evaluated as one means of improving the stability and precision of equating results.     

明代济宁左卫军屯王贵屯的由来

明洪武元年(公元1368年),置济宁左卫,景泰元年(公元1450年)调临清,改称临清卫,其军事屯田和屯田军仍坐落(驻防)于济宁州境内。王贵屯是济宁左卫(临清卫)在济宁州境内的军屯之一,是唯一用驻屯军官姓名命名的军屯;现分四村,隶于济宁市任城区喻屯镇。     

社会学视角下的农村留守子女教育问题

农村劳动力向城镇转移,产生了农村特有的群体——农村留守子女的群体。由于亲情和家庭教育的缺失,农村"留守子女"的成长、教育、心理和监护等产生了许多难以解决的问题,给少年儿童的教育与成长带来负面影响。     

理性颓退和销铄的挽歌——《我的菩提树》的一种解读

极"左"路线摧残下众多知识分子心理和灵魂颓退销铄经历了如下过程:首先,知识分子在"思想改造"和自虐阶段,已经丧失了独立的品格,丧失了人的尊严,粉碎了原有的智慧;其二,随着无休止的运动和批斗,使他们在出卖自己的同时,开始了对别人的出卖,在"文革"中形成了空前的自我厮杀,造成了民族心理的大变态;其三,知识分子在心灵粉碎堕落的同时,又面临着肉体也被毁灭的危险。经济贫穷,盛行封建迷信没有法制可言,劳改农场干部素质低下,是造成上述情形的主要原因。     

速度滑冰运动员心脏超声心动图的特征

为了探究速度滑冰运动员形态结构与功能特征,利用彩色多普勒血流显像仪对21名速滑运动员的左心室进行检查。发现以左心室后壁收缩末期厚度为代表的左心室收缩幅度指标明显异于普通人,女运动员尤为显著。     

高校校园足球运动员左心室功能的超声心动图研究

研究目的和方法:采用超声心动仪对比检测30名校园足球运动员和健康对照者的左心室功能,探讨足球运动训练对心脏形态功能的影响,为校园足球运动员的机能评定、选材和训练提供依据。研究结果和结论:与对照组相比,足球运动员的左心室壁厚度较大,为9.5±1.2 mm,对照组为8.2±1.3mm,其中有5名运动员的最大LVWT超过了预测值的上限,提示左心腔扩大(54.4±2.1mm;范围为52~60mm)。表明:与普通大学生相比,高校足球运动员在身体发育基本指标和心率、左心室结构和功能指标方面,均存在明显差异,而有训练的足球运动员学生的LVWT值更大,左心室腔扩大和泵血功能增强。长期有规律的足球训练对心脏形态功能具有一定的影响,这是运动员对足球专项训练特点良好适应的表现。     

THE INVISIBLE MADE VISIBLE

This article focuses on the early history of X-rays. It argues that, during the first years after their discovery in 1895 by German physicist Wilhelm Conrad Röntgen, they were regarded as a technological attraction and a visual medium. While their application in medical practice was not yet fully established, the possibility of seeing into the realm of the invisible encouraged pioneers of this technology to actively exploit their visual powers. By using a media-history framework, and relying on primary and secondary sources in English, German, French, and Italian, the article takes into account three aspects of the rays' early display: its character of technological attraction; its association with photography; and its connection to beliefs in the supernatural and the occult.     

The Anti-Black Order of No Child Left Behind: Using Lacanian psychoanalysis and critical race theory to examine NCLB

During a period in which institutions have been refashioned to meet the demands of a complex social and political economy, the No Child Left Behind Act (NCLB) has helped to alter the public educational system. As scholars and researchers examine the material effects of NCLB, efforts to improve the educational system and its effects must also explore the relationship between policy and racial ideologies including discursive fantasies. This article examines the relationship between NCLB and racial fantasies of Black youth as problematic others in order to help education reform scholarship and advocacy examine the violence of NCLB.     

Students Promoted Despite Test Failure

No Child Left Behind (NCLB) dictates students in Grades 3, 5, and 8 pass state tests to be promoted. Accordingly, most state education codes require students to pass reading and math exams for promotion. The majority of those who fail, however, appear to be promoted anyway. This article addresses core questions concerning the paradigm under which NCLB operates, what it means to promote or retain a student, and the consequences of these actions.
