基于跨理论模型的健康信息行为研究框架

健康信息是影响健康行为改变的主要因素,并且被认为可以促进健康行为的改变。本文应用跨理论模型的阶段划分理论,结合信息行为相关理论及特点,提出基于跨理论模型的健康信息行为研究框架,旨在为进一步深入探讨信息行为与健康行为改变之间的影响关系奠定基础。     

隐性教育资源在高校迎新工作中的运用

高校迎新工作时间短、任务重。在迎新工作中,从新生及家长等用户体验角度出发,运用“优化迎新流程、暖心迎新服务、热情朋辈引导、家庭教育沟通”等隐性教育资源,彰显学校以生为本的教育理念,使思想政治教育更为新生所接受,进而达到润物无声的育人效果。     

高职院校辅导员队伍的建设及可持续发展

高职院校辅导员队伍作为大学生思想政治教育阵地第一线的工作者,其自身建设与发展直接关系到大学生的德育工作和综合素质人才培养水平。在分析当前高职院校辅导员队伍现状的基础上,从建立机制、培养机制、考核机制、激励机制等方面阐述了如何促进辅导员队伍建设及可持续发展。     

高中生学业懈怠的成因及典型表现

学业懈怠是学生学习不努力的明显表现,是影响学生学习成效的主要内源性因素。高中生学业懈怠主要有五个方面的成因,即注意力涣散、学习目标模糊、学业自我妨碍、学习方法失调及消极学业情绪的影响。高中生主要存在学业准备性懈怠和任务操作性懈怠。     

Is short-term therapy really sufficient to eradicate Helicobacter pylori infection?

Objective:The aim of our study was to perform a systematic review and meta-analysis of the efficacy of short-term protocols for Helicobacter pylori eradication and to review the safety and adverse profiles of these eradication protocols.Methods:Literatures were located through electronic searches by PubMed,Medline,ISI Web of Knowledge,and Cochrane Library using the relevant terms.Abstracts of important meetings were searched manually in some journal supplements.Additional bibliographies were identified from the reference lists of identified studies.Three independent reviewers systemically identified randomized controlled trials(RCTs) comparing short-duration protocols vs.7-d proton pump inhibitor(PPI)-based triple protocols,as well as studies reporting eradication rates of short-duration protocols for H.pylori.Summary effect size was calculated as relative risk(RR) and 95% confidence intervals(CI) using Review Manager 4.2,and P0.05 was defined as statistically significant in all analyses.Results:Among 90 abstracts retrieved,15 studies were analyzed,including a total of 30 treatment regimens with 1856 subjects.Mean intention-to-treat(ITT) cure rates of 63.2% and 81.3% were achieved with short-term protocols and 7-d PPI-containing protocols,respectively.Per-protocol(PP)-based overall cure rates were 66.6% and 86.1%,respectively.Short-term therapy was inferior to 7-d triple regimen(P0.00001).After sub-analysis,however,comparing the effects of ≥3-d protocols and 7-d triple protocols,the cumulative ITT RR was 0.95(P=0.26),and PP RR was 0.95(P=0.10),without significant heterogeneity.Moreover,slightly fewer adverse-effects were found in short-term protocols.Conclusions:Although more economical,short-duration protocols are inferior to 7-d PPI-based triple protocols with regarding to eradication rate of H.pylori.Protocols of more than 3 d,however,may be equivalent to 7-d protocols.     

An intelligent electronic capsule system for automated detection of gastrointestinal bleeding

In clinical practice, examination of the hemorrhagic spot (HS) remains difficult. In this paper, we describe a remote controlled capsule (RCC) micro-system with an automated, color-based sensor to identify and localize the HS of the gastrointestinal (GI) tract. In vitro testing of the detecting sensor demonstrated that it was capable of discriminating mimetic intestinal fluid (MIF) with and without the hemoglobin (Hb) when the concentration of Hb in MIF was above 0.05 g/ml. Therefore, this RCC system is able to detect the relatively accurate location of the HS in the GI tract.     

基于EDA仿真软件的多资源调度算法

为提高电子设计自动化（electronic design automation,EDA）并行仿真任务的资源利用率并保证公平性,在占优资源公平分配机制（dominant resource fariness,DRF）的基础上,提出考虑license的占优资源公平分配（dominant resource fairness allocation algorithm considering license,LDRF）算法。一方面考虑多类型资源的公平调度问题,满足EDA任务对资源种类多样性的需求;另一方面考虑对EDA工具的license资源调度,避免任务占有硬件资源但是没有获得license授权不能运行,导致资源利用率下降。实验仿真结果表明,在license有限的条件下,LDRF的平均CPU资源利用率比DRF算法提高60%,平均内存资源利用率比DRF算法提高34%。     

化学学科能力的基本理论问题研究

我国《化学教学大纲》、《化学课程标准》、高考化学《考试大纲(大纲版)》、《考试大纲(课标版)》分别提出了不同内涵的化学学科能力要求,其原因在于,化学学科能力理论的建构缺乏明确的理论基础。为此,我们构建了智力—知识—技能—科学方法能力理论,提出了化学学科的核心能力——观察与实验能力、化学学习能力、化学思维能力、科学探究能力、实践与创新能力,并界定了其能力结构要素。这一能力观对于改变课程改革中能力内涵模糊、能力要求弱化的现状具有非常重要的现实意义。
