Liver fibrosis identification based on ultrasound images captured under varied imaging protocols

INTRODUCTION There are more than 20 million chronic hepatitis patients in China and 300,000 people die of liver related disease every year, which is widely recog- nized as an emerging public health crisis. Moreover, liver damage can cause higher than normal amounts of collagen fiber deposits in the extra-cellular spaces of the liver cells and cause the liver cells to lose blood and lead to liver fibrosis, which is a necessary stage to cirrhosis and a reversible consequence, so it is critic…

论教育考试作为意志协调的契约性——兼评考试性质之讨论

在考试应体现谁的意志的争论中,有四种代表性的观点:国家意志说,用户意志说,个人意志说,人类(社会)意志说。但上述观点并不能很好地概括考试的属性。为此,从国家、社会和个人的关系中,赋予考试内涵以新的阐释,即考试是三者之间意志协调的结果,其属性在于国家、社会和个人意志协调的契约。

智慧教育的三重境界：从环境、模式到体制

智慧教育作为教育信息化的高端形态,目前在全球范围内已受到越来越多的关注。虽然世界各国提出了不同的智慧教育方略,但智慧教育的愿景目标却都体现出打造智慧国家和城市、变革教学模式和培养卓越人才的主旨,因此需要从国家层面和文化境界来把握智慧教育。通过对现代教育系统的构成要素进行逻辑演绎,可以得出智慧教育系统包括智慧学习环境、新型教学模式和现代教育制度三重境界。智慧教育具有感知、适配、关爱、公平、和谐五大本质特征,通过智慧学习环境传递教育智慧,通过新型教学模式启迪学生智慧,通过现代教育制度孕育人类智慧。智慧教育的三重境界在＂智慧＂显现度、过程稳定性、涉及范围等方面呈现出明显的层级关系：从环境、模式到制度,＂智慧＂显现度呈现出从显性到隐性的特征,过程稳定性呈现出从动态到稳定的特征,涉及范围呈现出从微观到宏观的特征。

Design Features for Online Examination Software

Online education and computer‐assisted instruction (CAI) have existed for years, but few general tools exist to help instructors create and evaluate lessons. Are these tools sufficient? Specifically, what elements do instructors want to see in online testing tools? This study asked instructors from various disciplines to identify and evaluate the importance of several features that they want to see in testing tools. Along with standard elements, the respondents evaluated the importance of more advanced elements including adaptive responses and programmability, which would be used to add responsiveness and intelligence to provide more tailored questions and assistance. A latent variable analysis of the detailed model was performed and the results reveal that several advanced features not commonly available today would be useful to many instructors—particularly to handle higher level courses. Instructors teaching lower level courses tended to emphasize basic testing and simple grading features. The features were grouped into nine categories: question formats, feedback, programmability, grading, question bank, page display capabilities, platform, data analysis, and security. The results of the study examine the relative importance of the categories as well as the detail items within each category.

Syntactic Indeterminacy,Perceived Message Sensation Value-Enhancing Features,and Message Processing in the Context of Anti-Tobacco Advertisements An earlier version of this manuscript was presented at the 2004 National Communication Association Annual Convention in Chicago,IL, November 11–14, 2004

Fast-paced and arousing anti-drug ads, considered to have high perceived message sensation value (PMSV), enhance message processing and reduce drug use among young adults. Studies have yet to explore the relationship between specific, PMSV-enhancing message features and outcomes related to persuasion. Messaris’ (1997) concept of syntactic indeterminacy provides one plausible explanation for why message features contained in high PMSV ads might enhance message processing and subsequent changes in attitudes and behavior. The study explored this explanation by coding specific anti-tobacco ads for PMSV-enhancing features, merging these codes to a telephone survey among teens, and testing the relationship between message features and processing. The number of unrelated cuts and the use of suspenseful features (intense imagery and a second-half punch) increased message processing among older teens. An additive index comprised of these features was associated with message processing among both younger and older teens. Theoretical and practical implications are discussed.
