高校心理健康教育的科学构想

21世纪对人才培养提出了更高要求，高校思想政治教育工作日益加强，而心理健康教育作为其重要组成部分不容忽视，高校大学生心理健康状况不容乐观。本通过对当前我国高校大学生心理健康问题的现状进行分析，探讨高校心理健康问题形成的原因，并提出当前我国高校心健康教育的理论构想。     

Association between attitudes of filial responsibility and parent caregiving behavior

Objective: To analyze the association between attitudes of filial responsibility and adult child caregivers’ behaviors in the Southern Region of Brazil.

Methods: Cross-sectional study with 100 child caregivers of older adults. The data were collected through an interview using the protocol of filial responsibility adapted and validated to Brazilian Portuguese. Filial Expectation and Filial Piety scales evaluated the attitudes of filial responsibility. Caring behaviors assessed were: instrumental support, emotional, financial support, and companionship. The variables that presented p< .20 value in the bivariate analysis were inserted into a multivariate Poisson regression model.

Results: Financial and emotional support behaviors were significantly associated with filial piety (p = .050 and p = .001, respectively) and filial expectation (p = .013 and p = .023, respectively). Providing companionship was associated with filial piety (p = .015).

Conclusion: Attitudes of filial responsibility are associated with some but not all caregiving behaviors. Brazilians caring for older parents show more similarities to Chinese than to Canadian caregivers. Furthermore, filial responsibility and caregiving behaviors are strongly affected by Brazilian social and cultural norms. Reasons are discussed.     

前言

压电和声波理论与器件设计密切相关,特别是压电谐振器的工作原理就是材料中弹性波的压电效应。在信息技术高度发达的今天,压电谐振器作为最基本和最常见的敏感元件,在所有的通讯技术、电子电路、传感器和基于换能器的智能结构中都有着广泛的应用,也激发了固体力学界对这一现象展开大量的理论研究工作。可以说,压电现象作为桥梁将固体力学这一传统学科和新兴的信息技术、生物技术和近年来迅速发展的微机电(MEMS)技术等领域有机地联系了起来,无论从科学研究和工程应用的角度,都赋予了固体力学新的机会和生命力,也为研究和技术人员提供了具有…

The Nature of Scientific Practice and Science Education

There is, broadly speaking, an agreement within the international science education community that comprehension of the nature of science (NOS) should be a key element in the scientific literacy of citizens. During the last few decades, several didactic approaches have emerged concerning what and how to teach NOS. Also, one of the basic objectives of science education is for students to become familiar with the skills typical of scientific practice; however, there is little reference to their need to also acquire meta-knowledge about scientific practice (i.e., an understanding of the nature of scientific practice). Among other reasons, this may be due to NOS being essentially identified in most of the predominant proposals with the nature of scientific knowledge. But why not plan the teaching of science to be in tune with real scientific practice for students to learn about the nature of scientific practice at the same time as they are learning science? The answer to this question has given rise to a proposal grounded in ten essential pedagogical principles for the teaching and learning of science in secondary school. These are the principle of formulating questions, the principle of creativity and imagination, the principle of experimentation, the principle of procedural diversity, the principle of errors as opportunity, the principle of modeling, the principle of cooperation and teamwork, the principle of argumentation and discussion, the principle of communication, and the principle of evaluation. The purpose of this article is to present the justification and fundaments of these principles.     

中国文学史新"变"的三个视点

新时期中国学史的叙述在吸取前代和前期学史写作得失的基础上，不断深化着对学史的认识，以多元化的姿态不断丰富着学史的存在。他们的进步值得肯定，而困惑之处也值得反思，要改变困惑的局面，须求新“变”。求变的因素很多，我们的视点有三个：作方法论上的更新，学本位的回归，读接受的纳入。     

Fiber optic biosensor of immobilized firefly luciferase

Luciferase from firefly lantern extract was immobilized on CNBr-activated Sepharose 4B. The kinetic properties of immobilized luciferase were extensively studied. TheK _m′ for D-luciferin is 11.9 μmol/L, the optimum pH and temperature for Sepharose-bound enzyme were 7.8 and 25°C respectively. A luminescence fiber optic biosensor, making use of immobilized crude luciferase, was developed for assay of ATP. The peak light intensity was linear with respect to ATP concentration in range of 10⁻⁹–10⁻⁵ mol/L. A biological application was also demonstrated with the determination of serum ATP from rats bred in low versus normal oxygen environments.
