Elman神经网络在选煤厂配煤中的应用

配煤是选煤厂改善和稳定煤质的重要方法。在选煤厂配煤中,配煤煤质的准确预测是至关重要的,由于配煤的多种煤质指标与各组分的单煤种之间并非简单的加权关系,而是具有复杂的非线性关系。根据Elman神经网络模型能够逼近任意非线性函数的特点和具有反映系统动态特性的能力,采用Elman神经网络建立配煤煤质的预测模型。结果表明,Elman神经网络能够实现配煤煤质的预测,在实际工作中具有一定参考价值和指导意义。     

“文化转向”中译者角色的再思考

翻译研究中的"文化转向"体现了对翻译更深层次的理解,同时也促进了研究领域对跨文化翻译中译者角色的再思考。忠实与叛逆、归化与异化、缺省与补偿是跨文化翻译研究中的重要组成部分,也是译者在处理原文化与异文化中应考量的三个主要关系。促进各文化之间平等交流、和谐共生是新时期译者应承担的重要使命。     

Emotions involved in encountering classroom diversity: Beginning teachers’ stories

This article addresses emotions involved in encountering classroom diversity as appearing in beginning teachers’ stories. Previous research has pointed out that teachers’ emotions related to growing classroom diversity are seldom addressed, although increasing classroom diversity has been distinguished as a significant emotional challenge for teachers. In this article, teachers’ work is viewed as relational and moral work, in which emotions are inherently present. We conceptualise emotions as simultaneously social and individual. Instead of predefining the term ‘diversity’, we are interested in what kind of classroom diversity seems to become meaningful in teachers’ stories. The data consists of narrative interviews with seven Finnish beginning teachers. The findings illustrate how, in beginning teachers’ stories, students are both categorised and approached as unique individuals. Furthermore, the findings show diverse ways that emotions are present in teachers’ stories about classroom diversity, and how the working community also affects teachers’ emotions. We argue that teachers’ stories related to emotions and classroom diversity can be interpreted as moral negotiations, in which teachers’ own values and ideas of teaching are challenged. The findings of this article may add understanding of teacher–student relationships in diverse classrooms, and are also significant for teacher educators and teacher education programmes.     

Queering the Art Classroom: Queering Matters

Since 2003, successive British governments have taken steps to develop legislation supporting lesbian, gay, bisexual, transgender, questioning / queer, intersex, asexual and those who are gender / sexuality non‐conforming more generally (LGBTQIA+). In doing so, they have foregrounded the need for educational institutions to respond proactively to this legislation. There is evidence to suggest that homophobia is prominent in UK schools, yet measures to address the issue have largely rested on schools and LGBTQIA+ charities, reducing discussions of homosexuality to anti‐bullying discourses and introducing curriculum modifications that are overwhelmingly homonormative. The limitations of these current approaches ignore the societal and institutional power structures that help to produce homophobia, which is often referred to as heteronormativity. Drawing on aspects of new materialist and queer theoretical perspectives, this article follows the findings of a research project that focused on developing an intervention at GCSE level, exploring non‐normative genders and sexualities in the art curriculum. The research project was based on a class in a secondary school in North London from 2017 to 2018. Through the application of a pedagogy rooted in queer theory, the study explores the possibilities of disrupting heteronormativity and didactic learning by investigating student responses to the interventions. For this article, I focus on one student’s artwork and her reactions to the process of making her artworks during the project. As such, the study is an exploration of an attempt at moving beyond the homonormative inclusion of LGBTQIA+ content, towards a deeper exploration of gender and sexuality within the curriculum cultivated through making.     

The school parade as a text: the management of diversity on national commemorations in Greece

The paper approaches school parades on national commemorations in Greece as a ‘text’ for storing and transmitting cultural meanings and value hierarchies. The study is based on policy documents and participant observation. The detailed Ministry instructions on how schools should select students for the parade may be viewed as instructions on how to manage dimensions of diversity. Two such dimensions are tallness and achievement, established by law as selection criteria. The latter could point to both intellectual abilities and effort. However, because of the dominance of effort in Greek educational rhetoric, achievement comes to be perceived mainly as an indicator of moral qualities, e.g. hard work. The selected students are distributed along the body of the parade according to ‘syntactic’ rules, i.e. mainly ‘firstness’. Skilful management of bodily and moral ‘diversity’ makes underlying value hierarchies explicit, thus producing cultural meanings and turning the parade into a text about the nation.
