Drawing on a multi‐year qualitative study of immigrant and non‐immigrant youth storytelling, I describe youth's imaginative labour as they constructed and moved into one another's worlds. I argue that although multicultural literature is vital for affirming and expanding youth perspectives on their own and others' worlds, the publishing industry lags behind the immediate needs of immigrant youth to be understood and heard as fully human. Storytelling, in the form of co‐narration, creates an imaginative space of uncertainty and playfulness for inviting possible futures into mutual awareness and interpretation. Using two storytelling episodes as illustrations and drawing on contemporary sociocultural and decolonizing theories, I outline four ways future‐oriented teaching and research may be realized: (1) rename the world, by considering ‘what if’, (2) reframe narratives of damage so that narratives of desire may be foregrounded, (3) contribute to a more just and equal world rather than merely participate in existing practices and (4) reclaim childhoods for freedom and exploration, especially in our relations with Black and Brown youth who are perceived in adult terms much earlier than their White peers. I argue, overall, that we must understand and develop a contemporary theory of imagination in order to meet the challenges of future‐oriented literacy teaching and research.  相似文献

There is widespread system response to the perceived needs of education for twenty-first century, where learning-to-learn is privileged and schools are organised to prepare young people for work. One casualty of such skills-led teaching is deep thinking about curriculum questions and the knowledge contents of teaching in relation to the needs, motivations and experiential knowledge of students. In this paper we argue for greater conceptual clarity between curriculum and pedagogy, and between the worlds of children’s experience and disciplinary knowledge, in order to deepen teachers’ understanding of the practice of teaching. The paper shows how using the conceptual tools of curriculum making is key to becoming, and developing as a teacher. This paper supports subject specialism in teaching in a manner that respects the social and cultural capital of young people and their role in knowledge creation together with the emancipatory significance of gaining epistemic access to disciplinary knowledge.  相似文献

中国铝期货的长期限合约套期保值比率与绩效研究   总被引:1,自引:0,他引:1  
高勇  黄登仕  魏宇 《软科学》2008,22(3):45-48
对自2004年"国九条"颁布以来SHFE铝期货市场的长期限合约的套期保值比率与绩效进行研究,给出了一个寻求长期限合约的最优套期保值比率的新方法。为克服数据量较小的困难,运用新技术——协整序列分解模型进行研究,采用更一般的数据选取方法,发现不同的铝期、现货价格序列(二周、三周)均存在显著的协整关系;在此基础上得到任意期限的最优套期保值比率,所得结果与现有研究有明显不同:对于较长的套期保值期限,利用不同的时间单位进行套期保值,最优套期保值比率存在明显差异,但相差不大;利用较长时间单位的数据,得到的最优套期保值比率越大,对应的套期保值绩效也越好。  相似文献

股票指数期货是金融衍生工具是重要的一种,投资参与指数欺纲交易的实持是将现货市场的预期系统性风险转移至期货市场的过程,因此指数期货作为规避风险套期保值的有效工具在西方发达国家得到广泛应用。我国资本市场经过十年的发展,市场规模逐步扩大,投资整体素质不断提高,已经具备发展指数期货市场的基本条件。在国入WTO以后,我国资本市场要与国际市场全面接轨,扩大我国证券市场对外开放的程度已成必然。为迎接这一挑战  相似文献

为了考察我国大豆期货价格是否服从随机游走来验证大豆期货市场是否有效的命题,根据随机误差项的不同假定,将随机游走分为三种类型,以及每种类型所代表的市场效率,分别通过游程检验、技术分析检验和GARCH模型分析得出"我国大豆期货市场为弱式有效,并且是相对低效率的弱式有效"的结论。  相似文献

In order to investigate the nature of international crude oil futures and present evidence of long memory and nonlinear dependence for crude oil futures volatility as well as returns, a certain number of recent statistical tests, such as the powerful BDS test, the fractional integration test and other known statistics, are applied. The results show that though the returns themselves contain little serial correlation, the market volatility series have significant long-term dependence structures which may have important implications for volatility forecasts and derivative pricing. On the other hand, evidence of strong ARCH effect is also presented, and, moreover, the BDS statistics on the standardized residuals of the fitted GARCH model indicate that the ARCH-type process may generally explain the nonlinearities in the data. It seems that the crude oil futures market can be appropriately modeled by ARCH and fractal processes. These findings indicate that it would be beneficial to assess the behavior of the crude oil and price the oil derivative contracts by encompassing long memory and nonlinear structure.  相似文献

本文吸收组织生态学、组织学习理论和演化理论中关于年龄依赖性的观点,探究了组织年龄对金融创新的影响;更进一步地,以国家制度文化的视角,考察组织年龄在不同国家情境下的作用形态。本文的实证分析基于全球100多家期货交易所2000~2010年间的面板数据。结果表明,组织年龄与金融创新呈现U型关系;这种非线性关系在低经济管制、高不确定性规避的国家中更为显著。基于研究结果,本文提出促进我国金融机构发展,完善金融监管体系的建议。  相似文献
