传统知识的法律保护研究综述

随着国际经济全球化的进行，发达国家一方面不合理地利用发展中国家的传统知识进行牟利活动，另一方面通过知识产权制度强势保护他们在国际贸易中占优势的现代科技文化，保护传统知识近年来就逐渐成为发展中国家和发达国家争论的焦点。我国有着悠久的文明历史与丰富的民间文学艺术、中医中药等传统知识，如何回应国际上最新的趋势，保护、利用和发展我国的传统知识，近年来已成为理论界和实务界关注的热点话题。

Explanations of attitudes to change: Colombian mathematics teachers’ conceptions of the crucial determinants of their teaching practices of beginning algebra

This article arises from a study whose overall purpose was to investigate the relationship between Colombian mathematics teachers’ conceptions of beginning algebra and their conceptions of their own teaching practices. The teachers’ understandings of their teaching practices were explored with a view to unravelling their conceptions of change in their teaching. Focusing on the perspectives of teachers afforded opportunities that exposed the powerful role that the teachers’ conceptions of social/institutional factors of teaching played in their conceptions of their practices. The degree to which the teachers attributed these (external) factors as crucial reasons for what they do in their teaching was the basis of a categorisation of their conceptions of the crucial determinants of their teaching practices into three types. The findings are particularly relevant to our understanding of the stability of mathematics teaching approaches in the Colombian context but have likely implications for a range of international education contexts. Specific implications for the development of the research into teachers’ conceptions of mathematics and its teaching, and for teacher education programmes are presented.

Effects of osmotic stress on antioxidant enzymes activities in leaf discs of P<Subscript>SAG12</Subscript>-<Emphasis Type="Italic">IPT</Emphasis> modified gerbera

Leaf senescence is often caused by water deficit and the chimeric gene PSA612-1PT is an auto-regulated gene delaying leaf senescence. Using in vitro leaf discs culture system, the changes of contents of chlorophylls, carotenoids, soluble protein and thiobarbituric acid reactive substance （TBARS） and antioxidant enzymes activities were investigated during leaf senescence of PSA612-1PT modified gerbera induced by osmotic stress compared with the control plant （wild type）. Leaf discs were incubated in 20%, 40% （w/v） polyethylene glycol （PEG） 6 000 nutrient solution for 20 h under continuous light [ 130 μmol/（m^2·s）]. The results showed that the contents of chlorophylls, carotenoids and soluble protein were decreased by osmotic stress with the decrease being more pronounced at 40% PEG, but that, at the same PEG concentration the decrease in the transgenic plants was significantly lower than that in the control plant. The activities of superoxide dismutase （SOD）, catalases （CAT）, ascorbate peroxidase （APX）, guaiacol peroxidase （GPX） and dehydroascorbate reductase （DHAR） were stimulated by PEG treatment. However, the increases were higher in PSA612-IPT transgenic plants than in the control plants, particularly at 40% PEG treatment. Lipid peroxidation （TBARS content） was increased by PEG treatment with the increase being much lower in transgenic plant than in the control plant. It could be concluded that the increases in the activities ofantioxidant enzymes including SOD, CAT, APX, GPX and DHAR were responsible for the delay of leaf senescence induced by osmotic stress.     

Communicating feedback in teaching practice supervision in a learning-oriented field experience assessment framework

This article seeks to understand the ways in which feedback was communicated in post-observation conferences in teaching practice supervision within the learning-oriented field experience assessment (LOFEA) framework. 32 post-observation conferences between 21 pairs of supervisors and participants of in-service teacher education programmes, and interviews with supervisors and participants were analyzed, with findings revealed in four themes:

1.

The distribution of content and nature of feedback in post-observation conferences;

广告语中“我”和“我们”的功能分析

本文结合广告模因这一概念,从交际角色这一角度出发来分析第一人称指示语＂我＂和＂我们＂在广告语篇中的功能,认为采用第一人称指示语字眼的广告语常采用情感式模因。以年轻消费者为主要受众的广告习惯采用带有＂我＂字的广告语,抓住年轻人强烈的自我凸现、寻找归属感的心理;而采用＂我们＂二字的广告语不仅拉近了广告主和广告受众间的距离,引起两者的共鸣,而且在某些情况下,还能起到自评和评他的作用。
