《白鹿原》性别政治背后的民族命运——以田小娥形象为中心

作为90年代小说的扛鼎之作,《白鹿原》对民族文化命运的思考在其塑造的诸多女性形象上亦可见出。本文以田小娥形象为中心,通过分析这一＂新＂人形象身上的传统守旧因素,辨析其中凸显的性别政治关系,认为不仅女性悲剧命运的主因是其传统的守旧性,甚至民族命运的曲折走向也可在其中寻到端倪。

G．A．科恩对马克思拜物教理论的解读研究

20世纪70年代以来,分析马克思主义作为西方马克思主义的主流开始流行,作为分析马克思主义的领军人物,G．A．科恩见证了它的繁荣和衰退。那至于为何衰退？或许G．A科恩在展示马克思拜物教思想时已见端倪。他在解读马克思拜物教思想的逻辑起点和基本内容后,呼吁消灭形式的统治,实现内容的解放,为共产主义的历史必然实现作了辩护。     

5G and Smart Education: Educational Reform Based on Intelligent Technology

The 5G communication technology serving a wide range of vertical industries is maturing, which provides a possible boost for the development of smart education and lays a foundation for solving the principal contradiction in current education. With the characteristics of ultra-high speed, low latency, low energy consumption, massive network capacity, and high reliability, the 5G technology is applied with other technologies like artificial intelligence (AI), internet of things (IoT), big data, and blockchain to promote the application upgrading of intelligent education technology. This paper analyzes the intelligent education technology and its eight typical applications in the 5G era, which include smart safe campus, integrated learning spaces, synchronous cyber classrooms, teachers’ professional development, robot learning partners, mobile and ubiquitous learning, virtual simulation training, and smart e-textbooks. Then, it discusses how intelligent education technology promotes changes in the modes of learning and teaching in the 5G era from three dimensions: individual learning, collaborative group learning, and classroom-based collective teaching. At last, the framework of smart education in the 5G era is proposed from the perspectives of intelligent education technology and its typical applications, changes in learning and teaching, and the new ecosystem of smart education.     

WCDMA关键技术的研究简

WCDMA技术的设计目标是不仅能够提供比第二代移动通信系统更大的容量和更好的通信质量．而且要能在全球范围内更好地实现无缝漫游并为用户提供语音、数据和移动多媒体等业务。与第二代移动通信相比,WCDMA系统采用直扩序列码分多址技术（DS—CDMA）,信息被扩展成3．84Mchip／s后在5MHz带宽内传送,同时采角了多种关键技术保证业务质量（QoS）。概括来说,WCDMA关键技术主要包括RAKE接收技术、无线资源管理技术、多用户检测技术和智能天线技术等。

Evaluation of usage of virtual microscopy for the study of histology in the medical,dental, and veterinary undergraduate programs of a UK University

This article describes the introduction of a virtual microscope (VM) that has allowed preclinical histology teaching to be fashioned to better suit the needs of approximately 900 undergraduate students per year studying medicine, dentistry, or veterinary science at the University of Bristol, United Kingdom. Features of the VM implementation include: (1) the facility for students and teachers to make annotations on the digital slides; (2) in‐house development of VM‐based quizzes that are used for both formative and summative assessments; (3) archiving of teaching materials generated each year, enabling students to access their personalized learning resources throughout their programs; and (4) retention of light microscopy capability alongside the VM. Student feedback on the VM is particularly positive about its ease of use, the value of the annotation tool, the quizzes, and the accessibility of all components off‐campus. Analysis of login data indicates considerable, although variable, use of the VM by students outside timetabled teaching. The median number of annual logins per student account for every course exceeded the number of timetabled histology classes for that course (1.6–3.5 times). The total number of annual student logins across all cohorts increased from approximately 9,000 in the year 2007–2008 to 22,000 in the year 2010–2011. The implementation of the VM has improved teaching and learning in practical classes within the histology laboratory and facilitated consolidation and revision of material outside the laboratory. Discussion is provided of some novel strategies that capitalize on the benefits of introducing a VM, as well as strategies adopted to overcome some potential challenges.

An enriched multimedia eBook application to facilitate learning of anatomy

This pilot study compared the use of an enriched multimedia eBook with traditional methods for teaching the gross anatomy of the heart and great vessels. Seventy‐one first‐year students from an Australian medical school participated in the study. Students' abilities were examined by pretest, intervention, and post‐test measurements. Perceptions and attitudes toward eBook technology were examined by survey questions. Results indicated a strongly positive user experience coupled with increased marks; however, there were no statistically significant results for the eBook method of delivery alone outperforming the traditional anatomy practical session. Results did show a statistically significant difference in the final marks achieved based on the sequencing of the learning modalities. With initial interaction with the multimedia content followed by active experimentation in the anatomy lab, students' performance was improved in the final test. Obtained data support the role of eBook technology in modern anatomy curriculum being a useful adjunct to traditional methods. Further study is needed to investigate the importance of sequencing of teaching interventions. Anat Sci Educ. 7: 19–27. © 2013 American Association of Anatomists.     

Interactive radiological anatomy eLearning solution for first year medical students: Development,integration, and impact on learning

A technology enhanced learning and teaching (TELT) solution, radiological anatomy (RA) eLearning, composed of a range of identification‐based and guided learning activities related to normal and pathological X‐ray images, was devised for the Year 1 nervous and locomotor course at the Faculty of Medicine, University of Southampton. Its effectiveness was evaluated using a questionnaire, pre‐ and post‐tests, focus groups, summative assessment, and tracking data. Since introduced in 2009, a total of 781 students have used RA eLearning, and among them 167 Year 1 students in 2011, of whom 116 participated in the evaluation study. Students enjoyed learning (77%) with RA eLearning, found it was easy to use (81%) and actively engaged them in their learning (75%), all of which were associated to the usability, learning design of the TELT solution and its integration in the curriculum; 80% of students reported RA eLearning helped their revision of anatomy and 69% stated that it facilitated their application of anatomy in a clinical context, both of which were associated with the benefits offered by the learning and activities design. At the end of course summative assessment, student knowledge of RA eLearning relevant topics (mean 80%; SD ±16) was significantly better as compared to topics not relevant to RA eLearning (mean 63%; SD ±15) (mean difference 18%; 95% CI 15% to 20%; P < 0.001). A well designed and integrated TELT solution can be an efficient method for facilitating the application, integration, and contextualization of anatomy and radiology to create a blended learning environment.
