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．     

贝娄小说中知识分子夫妻之间的权力关系

美国诺贝尔文学奖得主索尔·贝娄小说中知识分子夫妻之间的权力关系有三种模式 :竞争、控制、平等 ;两种性质 :压抑性和生产性。作者在小说中 ,对压抑性的权力关系作否定、贬抑的描绘 ;对生产性的权力关系作肯定、赞美的描述。贝娄的小说通过揭示男女知识分子之间的权力关系 ,突出了这些女性人物本身的知识品格和职业道路。

面向储能的光伏微网成本评价与对策研究

微电网是智能电网的重要组成部分,可以有效协调区域内的电力资源。为研究面向储能的光伏微网电力成本变化情况和优化对策,基于微网多主体结构构建微网电力成本均衡模型,以微网内分布式光伏供应及用户电力需求的统计数据为主要输入对象,并设置变量来区分不同情景下的分布式可再生能源发电量,建立以时间为自变量的微网分布式电力收益函数和用户购电成本函数,刻画微网电力资源调度的动态均衡变化。基于微网电力资源调度实例,发现微网在并网情景下的购电成本小于储能情景下的购电成本（C并=2 033.6元C储=2 633.6元）,且储能情景下购电成本的22.8%都来自储能设施的日折旧费,因此,加大科技研发和增强微网协同管理可以降低微网成本。     

Information and communication technology adoption in micro and small firms: Can internet access improve labour productivity?

The rapid spread of information and communication technologies (ICT) may increase firms’ productivity with important consequences for job creation and for economic growth. This article contributes to this discussion by analysing the impact of internet adoption on labour productivity and the mechanisms shaping this relationship in Peruvian micro and small manufacturing firms over the period 2011–2013. The article estimates a reduced form where labour productivity is a function of internet adoption and other explanatory factors. Internet adoption is instrumented using a measure of the availability of financial opportunities for micro and small firms in Peru. Findings indicate that internet adoption: (a) increases firms’ labour productivity; (b) reallocates employment away from temporary administrative workers and non‐remunerated workers and expands employment of permanent production workers; (c) leads to the formalization of labour relationships, to the implementation of new organizational practices and to the improvement of training measures. While changes in employment and formalization of workers are linked to labour productivity gains, increases in training measures and organizational changes do not generate any additional productivity increase. Policies oriented to promote the adoption of ICT in micro and small firms can be beneficial to close the productivity gap with larger firms in Peru. Moreover, policies directed to the formalization of the workforce can provide an extra benefit, i.e. additional labour productivity gains in firms adopting the internet. Finally, policies oriented to the development of digital skills are also important to ease the re‐employment of those workers losing their jobs and the achievement of additional productivity gains that new organizational practices can provide.     

Micro‐investment perspective and the potential of the universal basic income

The article evaluates prospects of the Basic Income (BI) as a development policy tool. While BI is a relatively new initiative within development policy, the article argues that it should be seen as a serious option in the future, given the changing geography of poverty and the findings from existing cash transfer schemes. The analysis is carried out as a synthesis of existing findings on BI pilot programmes, along with cash transfer instruments more generally. While not including new empirical data, the synthesis allows preliminary estimates on the likely impacts of abolishing conditioning and targeting in cash transfer schemes. Particular attention is paid to the notion of micro‐investment and the psychological conditions of micro‐investment.     

微技术传播对青年人信仰的影响研究

以微博和微信为代表的微技术深刻影响着青年人的思维方式、行为方式、价值方式。同时,微技术在传播信仰过程中改变了传统的信仰格局,打破了政治输入和输出的传统信仰架构。青年不但成为了微技术信仰语言的创造者,也有着强烈的信仰平等诉求。在微技术时代,实现信仰治理的优化刻不容缓。     

Note passing as gendered practices of public ambiguity in a hyper‐masculine organization

This article explores a surprising and seemingly mundane organizational practice: passing notes during professional meetings. Based on 34 in‐depth interviews with women in a hyper‐masculine organization — the Israeli military — this study focuses on what I term gendered practices of public ambiguity. It demonstrates how these practices shed light on three interrelated paths to power at work: (i) practices of public intimacy between men; (ii) practices of women's degradation by men; and (iii) practices of recognition claims by women. The tension between the publicity inherent in the routine passing of notes and the ambiguity of their contents calls for a more nuanced theorization of gendered power practices, which transcends the accepted dichotomy of doing and undoing gender, reproducing or challenging the symbolic gender order. The findings show that gendered micro‐practices can become polysemic symbolic spaces in which women redirect the flow of power, if only temporarily and locally, and turn it into a multidirectional and multi‐agentic resource. The conceptual contribution of these findings is discussed in terms of the positioning of women in hyper‐masculine environments as pragmatic subjects who (re‐)construct mechanisms of power out of the restricted repertoire available to them.     

小微企业网贷风险定价模型研究

对小微企业网贷平台的运营模式进行深入分析,发现其运行机制包括需求的同质化解构、需求的模块化生产、需求的风险评估、个性化需求加总,在此基础上构建小微企业网贷风险定价模型。为验证模型的有效性,抽取国内典型互联网金融平台“人人贷”上近期发生的小微企业标的并进行风险定价,将定价结果与实际利率进行比较,发现该模型适用于“卖方市场”的小微企业网贷,能够提供差异化的贷款利率,从而向小微企业提供个性化的网贷产品。     

网络集群的自组织特征 —— 以“南京梧桐树事件”的微博维权为个案

近年来,伴随着急剧的社会结构转型,我国新的社会身份和社会认同群体也随之产生,在网络中的政治表达和利益维护活动增多,在这些网络讨论的集群内部,参与者会自发形成一定的秩序,推动事件的进行。本研究利用自组织理论作为分析框架,选取"南京梧桐树事件"的微博维权集群为研究对象,重点考察网络集群参与者之间从无序到有序的互动过程、整个系统的演变规律及其与外界的互动机制,由此总结出网络集群中的自组织特征,从而相对准确地把握虚拟社区系统的发展、演化阶段,为更好地理解互联网的社会功能起到借鉴作用,也为政府有关部门做好群体事件的预防工作提供理论和策略上的支持。
