化学新课程改革与微型化学实验

新一轮基础教育改革中，化学新课程改革在理念和内容上都强调学习方式的转变，即倡导探究性学习．探究性学习的实质，是学生主动参与教学过程，积极从事各种探究活动，亲自发现科学概念和原理，掌握探究技能．事实表明微型化学实验是实现探究性学习的有效手段．     

薛宝钗另无情缘——与田同旭先生商榷

田同旭先生撰《薛宝钗另有情缘》一文 ,认为薛宝钗婚姻之最后归宿 ,在贾宝玉出家以后 ,再适贾雨村。[1] 今据《红楼梦》第五回“贾宝玉神游太虚幻境”中词曲、册图的谶语式暗示 ,以及看到八十回后原稿结局的脂砚斋批语的分析 ,薛宝钗另适贾雨村之说不能成立     

声乐的有效教学探析

长期以来,我国声乐教学一直存在着教学观念陈旧、教学简单、教学手段落后、师资水平参差不齐等诸多问题,导致声乐课堂教学效率低、人才培养周期长,甚至最终难以成才,严重地阻碍了我国大批声乐人才的脱颖而出。因此,必须大力提倡并实施有效的声乐教学。     

In the flesh: a poetic inquiry into how fat female employees manage weight-related stigma

ABSTRACT

This paper engages with the question of how fat female employees manage weight-related stigma at work. We use poetic inquiry to show the reader how it feels for our participants to be stigmatized based on their size. We interviewed 22 women who self-identify as full-figured, fat, overweight, or obese. The results consist of six poems, five of which were written by us, the researchers. These ‘tri-voiced poems’ (Leavy 2010b) illustrate the spectrum of affective responses and stigma management strategies that our participants talked about, ranging from feeling anxious, super-smart, impeccable, and funny to rebellious and confident. The sixth poem was written by one of our participants and voices her first-person experiences and perspective. Our aim is to do justice in our writing to the emotions that circulated in the interviews and to make a political statement with regards to the stigmatizing practices in organizations related to size and health.     

Undercover policing and the spectre of ‘domestic extremism’: the covert surveillance of environmental activism in Britain

The spectre of environmental ‘domestic extremism’ has long been postulated by police leaders and security analysts in Britain. It is a narrative that has justified the commitment of enormous amounts of government resources towards police intelligence work directed at non-violent direct action campaigns. Most controversially, this has included the long-term infiltration of environmental (and other) activist groups by undercover police. This article provides a critical analysis of the justifications put forward in support of the covert surveillance of environmental activists in Britain. The paper proceeds by way of a single case study – a high profile, environmental direct action protest in the north of England – in order to reveal the levels of abuse, manipulation and deception at the basis of undercover protest policing. Through their court case, the activists involved with this action were able to obtain rare insights into the police authorisation documents for the undercover operation that had led to their arrests. An analysis of these documents provides us with a glimpse of the contradictory justifications given by senior police officers for infiltration – now under scrutiny by a public inquiry.     

Developing a multi-level organization-public dialogic communication framework to assess social media-mediated disaster communication and engagement outcomes

Dialogic communication has long been viewed as vital for effective organization-public relations. Yet, it is under-theorized whether and how organizations’ disaster communication messages may embody dialogic communication principles, and how various dialogic features are associated with different public engagement outcomes on social media. Extending the Organization-Public Dialogic Communication (OPDC) framework to the context of social media-mediated disaster communication, we propose a multi-level framework to assess the dialogic capacity of Facebook messages sent by disaster management organizations during a natural disaster. Three levels of dialogic communication characteristics (i.e., message structure-level, topic-level, and linguistic level) are examined using content analysis and Linguistic Inquiry and Word Count (LIWC). Results identified media richness, correcting, and confirming topics as three consistent predictors of public engagement of all types. Meanwhile, there exhibit greater variations regarding how other topical features and linguistic characteristics are related to public’s cognitive, emotional, and behavioral engagement during a disaster.     

论探究概念在杜威哲学中的重要地位

“探究”是杜威思想中的一个核心概念,可以看作是杜威思想的核心方法论,用探究概念来建构杜威的思想体系,可以把杜威在形而上学、语言哲学、知识论、逻辑思想等相邻领域的理论整合起来,这样能够比较全面地展现杜威在这方面的思想全貌。杜威的“真理观”、“发生学方法”、“经验自然主义”、“工具主义”、“操作主义”等也可以纳入到这体系之中来进行探讨。     

基于实证调查的街旁绿地价值研究——以舟山浦西公园为例

街旁绿地是城镇空间中可供民众游憩、观赏、健身、幽会的边角小空地,由于其微小且零散依附于主要建筑环境与交通流线之间,极易被忽略、侵蚀或转换成其他商用价值较大的功能空间。通过实地踏勘、观察体验、问卷调查及专题访谈等综合实证调查,分析总结民众对舟山浦西街边绿地公园的使用现状及期望,提出街旁绿地景观环境的优化策略,以期创造一个民众喜爱的城镇景观生态不可或缺的人性化场所,为城镇设计提供借鉴。     

探究式教学模式在排球教学中的应用研究

运用实验法、文献资料法、问卷调查法等研究方法,以东北师范大学2010级体育学院体育教育专业的60名学生为研究对象,通过构建探究式教学模块对研究对象进行传统的排球教学和探究式排球教学。结果表明:探究式教学方法可以广泛应用于排球教学中;探究式教学法和传统的排球教学法相比,可以取得更好的教学效果,提高学生的专项运动成绩,激发学生的学习兴趣并且改变学生学习态度。     

“立三路线”内涵考辨

与现今理解的“立三路线”不同 ,由李立三在中央政治局讲话引起的 ,在共产国际看来李立三及当时中央所具有的“反共产国际”思想是“立三路线”的原始内涵。
