Enhanced teaching and student learning through a simulator-based course in chemical unit operations design

This paper illustrates a teaching technique used in computer applications in chemical engineering employed for designing various unit operation processes, where the students learn about unit operations by designing them. The aim of the course is not to teach design, but rather to teach the fundamentals and the function of unit operation processes through simulators. A case study presenting the teaching method was evaluated using student surveys and faculty assessments, which were designed to measure the quality and effectiveness of the teaching method. The results of the questionnaire conclusively demonstrate that this method is an extremely efficient way of teaching a simulator-based course. In addition to that, this teaching method can easily be generalised and used in other courses. A student's final mark is determined by a combination of in-class assessments conducted based on cooperative and peer learning, progress tests and a final exam. Results revealed that peer learning can improve the overall quality of student learning and enhance student understanding.

基于社会资本理论的大学生社交媒体多任务使用效果研究

在使用社交媒体的人群中,大学生群体对社交媒体的多任务使用与其学业成绩之间有着怎样的内在关联属性,对其社会资本的积累产生怎样的影响是本文的研究问题所在。对研究问题的原因进行探索性分析,研究发现,出于学习或娱乐目的的社交媒体多任务使用对大学生的学业成绩呈现负相关,不利于其学业成绩的提高,阻碍学习进程健康、科学开展,不利于其社会资本的正向积累。

浅析药价改革的市场效应

针对医院药品收入占总收入的比重过高、社会药费负担过重现象，浙江省物价局出台了旨在抑制药价虚高的改革措施取得了显成效：规范了医疗机构药品集中招标的价格行为，降低了药品价格，调整了医疗机构医药收入结构，扭转了”以药养医”的局面；健全了价格监督检查机制。在医疗机构药品收入大幅度降低的情况下．如何进一步保障人民群众的医疗需求、促进医疗机构持续稳定发展提出相应的设想与建议。     

学术期刊审稿人力资源的开发和利用

学术期刊优化审稿人员配置和使用的关键在于改变目前松散粗放的选用方式,转向系统集约的审稿人力资源开发和利用。学术期刊编辑部必须遵循一般规律,坚持基本原则,明确主要途径,选择恰当技术,科学开发审稿人力资源。同时,要采取得力措施,充分、合理地利用内部审稿人力资源和外部审稿人力资源。     

Pattern design on 3D triangular garment surfaces

This paper focuses on a pattern design method for a 3D triangular garment surface. Firstly, some definitions of 3D style lines are proposed for designing the boundaries of patterns as drawing straight lines or splines on the triangular surface. Additionally some commonly used style lines are automatically generated to enhance design efficiency. Secondly, after style lines are preprocessed, a searching method is presented for quickly obtaining the boundaries and patches of a pattern on the 3D trian- gular surface. Finally a new pattern design reuse method is introduced by encoding/decoding the style line information. After style lines are encoded, the pattern design information can be saved in a pattern template and when decoding this template on a new garment surface, it automates the pattern generation for made-to-measure apparel products.     

呈现精神世界的真实性--《无名的裘德》中意象和对比手法的象征性运用

<无名的裘德>中意象和对比及其在叙事过程中的相互回应,一方面理性而含蓄地赋予小说中的事件、人物及其价值观以象征性的评判,使小说的逻辑叙事更加密集,小说层次更加丰富;另一方面,所有这些意象、对比的象征性运用,同时表达了哈代的哲学思想和价值观,即上帝或操纵宇宙的力量对人及其命运的漠视以及现代社会的躁动性.
