Modelling pre-service teachers’ perceived usefulness of an ICT-based student-centred learning (SCL) curriculum: a Singapore study

The purpose of this study is to examine the factors that influence pre-service teachers’ perceived usefulness of an Information and Communication Technology (ICT) course that was conducted using the student-centred learning (SCL) approach. In this study, perceived usefulness was used as the dependent variable and perceived competence, course delivery, facilitating conditions and learning environment as independent variables. The results of this study showed that perceived competence and course delivery have direct effects on pre-service teachers’ perceived usefulness of the course, while learning environment and facilitating conditions affect perceived usefulness indirectly. Overall, the results support the hypothesis that the four selected variables in this study affect perceived usefulness and that the resulting model is an adequate fit to the observed relationships among the factors that influenced pre-service teachers’ perceived usefulness of an ICT course.     

Establishment of gender- and age-specific reference intervals for serum liver function tests among the elderly population in northeast China: a retrospective study

IntroductionReference intervals (RIs) for younger population may not apply to the elderly population. The aim of this study was to establish gender- and age-specific RIs for serum liver function tests among the elderly population and to compare with younger population RIs currently used in China and other countries.Materials and methodsThis was a retrospective study, and subjects (≥ 18 year-old) were recruited from the laboratory information system (LIS) at the First Hospital of Jilin University between April 2020 and April 2021. The following parameters were collected: aspartate aminotransferase (AST), alanine aminotransferase (ALT), gamma-glutamyltransferase (GGT), alkaline phosphatase (ALP), total protein (TP), albumin (ALB), total bilirubin (TBIL), and direct bilirubin (DBIL). The Tukey method was used to eliminate outliers. Reference intervals were established by the nonparametric method.ResultsA total of 23,597 healthy individuals were enrolled in the study. From all parameters AST, ALT, TP and ALB required no gender partition, while ALT, GGT, TP, ALB and DBIL required different partitions for age. Activities and concentrations of ALT, ALB, and TP showed a downward trend in the elderly aged 60-89. In contrast, DBIL showed a gradual upward trend.ConclusionThe RIs for liver function tests among healthy elderly population were different from those among young population in China. There were apparent gender and age differences in the RIs of liver function for elderly and significant differences compared with national standards and RIs in other countries. Therefore, it is necessary to establish gender- and age-specific RIs for serum liver function tests among the elderly population.     

论基层党校加强党史教学的必要性

中国共产党的历史是一笔重要的精神财富,党校教学一直把党史课作为一门重要课程来抓。中国共产党成立以来,党的领导人历来重视党史学习,党校作为党员干部培养的主要阵地,加强党史教学,这将对提高党员干部的理论素养、提高党的执政能力具有重要意义。在基层党校,党史教学应突出地方特色,提高学员的工作办事能力,为当地的发展建设做贡献。

对高职教育“高等性”与“职业性”融合的思考

"高等性"与"职业性"是高职教育的根本属性。高职教育要实现内涵发展,必须坚持层次和类型的和谐统一,在"职"字上办出特色,不断彰显其职业性以体现其核心价值和优势所在;在"高"字上凸显水平,不断彰显其高等性以提高其整体品质和核心竞争力。这既是高职教育全面提高人才培养质量的基本要求,也是高职教育面向未来,实现其可持续发展的现实需要。从科学定位人才培养目标和规格、提升教师队伍整体水平、培育大学文化和精神等三个方面对实现"高等性"与"职业性"的和谐统一进行系统思考,提出对策和建议。

基于小生境免疫算法的阵列天线方向图零点生成技术

本文将小生境思想融入到免疫算法中,提出了一种小生境免疫算法。该算法对抗原识别后的抗体种群用小生境技术进行重构,将搜索空间划分为各自独立的小生境,并在各小生境内独立搜索,增强了抗体的多样性;引入小生境共享机制,用共享度控制抗体的促进和抑制,适当抑制高亲和度抗体的繁殖,克服了精英种群的冗余。将提出的小生境免疫算法(NDC_IA)应用于阵列天线方向图零点生成技术中,得到了较好的优化效果。     

行动导向：“技术文化教育”的教学理念——基于黄冈职院推行“行动导向”教学法的再认识

戴仕弘教授在黄冈职院的学术讲座,引起理论与实践的争议,实质是认识问题,理解问题。本文试图从高职教育文化分类上,回答为什么要推行“行动导向”、“行动导向”是什么以及推行“行动导向”有什么困难三个方面的问题,以对我院技术文化建设和行动导向教学法的推行提供参考。
