For what purpose the arts? An analysis of the mission statements of urban arts high schools in Canada and the United States

While general arts programs have declined in many schools across the United States and Canada, the number of specialized art programs in public secondary schools has swelled since the 1980s. While this increase is often celebrated by arts educators, questions about the justification of specialized arts programs are rarely raised, and their value is often taken for granted. In this article, we examine the mission statements of eighty-four specialized arts programs across two countries to examine the ideas, values, and commitments that are expressed in these public statements. In addition to a close thematic analysis, we describe how these mission statements reflect different conceptions of the role of the arts in education and consider the ways in which arguments that seek to broaden access to the arts are combined with the goal of serving a narrow subset of the student population. We argue that analyzing mission statements provides a clearer picture of the ideas that shape these programs, and that in order to foster an informed public conversation about the purpose and value of an education in the arts, educators committed to the arts must engage in this serious discussion.     

文化景观作为区域景观研究概念——德国图林根州文化景观研究、教学与规划实践

近20 年来,对风景园林的文化阐释成为埃尔夫特应用科技大学文化景观研究组持续以来的关注焦点。期间,该研究组系统地分析了决定图林根州文化景观的各种文化因素和要素,深入了解文化和自然环境中的复杂相互作用,以此来表述和研究图林根州的区域景观系统。首先,阐述了当下德国风景园林学术语境中“文化景观”的含义,强调文化对于景观质量的价值。继而,论述了对景观进行优化、保护和设计中无法否定和回避的文化与经济因素。这样既要发展经济又要保护文化的矛盾性质,是文化景观概念所理解的人类生存的重要性质所在。文化景观研究能够在看似统一的地理区域中,形成和发展为具有可识别性的、差异化的动态结构。此外,文化景观研究还涉及其他因素,诸如生物多样性与文化多样性的丧失、生态系统服务功能滞后、经济价值的低估、国土空间连接性以及缺少实质性评价的人文特征。对历史性文化景观价值的认知给风景园林学带来了机遇,对历史景观不仅要保护,而且要创造并提供各种富有成效的展示,以参与文化景观的未来发展。维护和整合风景园林规划设计中文化景观遗产的研究实践,可以通过基础设施项目的环境影响评估到建成区的景观设计整体过程中得以贯彻。更好地理解文化景观,有助于在空间规划和发展中对其更加谨慎地进行处理,以提高文化景观研究的科学和策略意识。     

基于景观感知的自然教育环境设计策略与要素研究

景观感知作为自然教育非常重要的组成部分,其研究内容受到广泛关注,但现有研究仍处于初步阶段,未对自然教育环境设计起到应有的支撑作用。从景观感知角度,综合环境教育学、环境心理学及行为心理学等相关理论,对基于景观感知的自然教育环境的营建提出了针对性原则及策略,并着重探讨影响景观感知的设计要素。首次从景观感知角度对自然教育环境设计进行探讨,对自然教育环境的营建具有指导意义。 关键词：风景园林;自然教育;景观感知     

Differential seminal plasma proteome signatures of acute lymphoblastic leukemia survivors

With advances in therapeutic methods, there is a high survival rate among leukemia patients, of an extent more than 80%. However, chemotherapeutic drugs used to treat these patients have adverse effects on their overall health profile including fertility. The primary aim of this study was to identify differentially expressed proteins in seminal plasma of acute lymphoblastic leukemia (ALL) survivors compared to age-matched healthy controls, which can provide molecular basis of idiopathic infertility in such survivors. Differential proteome profiling was performed by 2D–differential in-gel electrophoresis, protein spots were identified by mass spectrometry and selective differentially expressed proteins (DEPs) were validated by western blotting and ELISA method. Out of eight DEPs identified, five proteins (isocitrate dehydrogenase 1, semenogelin 1, lactoferrin, prolactin-inducible protein, and human serum albumin) were upregulated and three (pepsinogen, prostate specific antigen and prostatic acid phosphatase) were downregulated. Expression profiles of these proteins are suggestive of reduction in semen quality in ALL survivors and can further be explored to determine their fertility status.     

Reimagining policy: Power,problems, and public stories

The authors of various practitioner and scholarly documents suggest markedly contrasting understandings about the nature of “policy.” These divergent conceptions raise the question: What is at stake by understanding the nature of policy in one way as opposed to another? The purpose of this philosophical inquiry is to interrogate the nature of “policy” as it relates to music education and to question the values that do and might underlie and propagate through contrasting understandings of “policy.” Subsequently, I examine two aspects of policy, problem identification and meaning-making, that have gone largely unexplored in the arts education literature.

Using Foucault's writings, I argue that power-laden policy texts often have the greatest impact, not when they are mandated, but when they go misrecognized as common sense. I also advocate for the consistent use of the terms “policy texts” and “policy actions,” including as an alternative to the imbalanced designations of “soft policies” and “hard policies.” Drawing on Dewey arts educators might form “publics” around problems having consequences that they deem far-reaching, recurrent, and irreparable. Individual and collective political narratives, including what Ganz explains as “stories of self,” “stories of us,” and “stories of now,” can foster the meaningful connections necessary for forming “publics” who address pressing problems in arts education.     

Interactive Visualization and Industrial Ecology: Applications,Challenges, and Opportunities

The emergence of increasingly complex data in industrial ecology (IE) has caused scholarly interest in interactive visualization (IV). IV allows users to interact with data, aiding in processing and interpreting complex datasets, processes, and simulations. Consequently, IV can help IE practitioners communicate the complexities of their methods and results, shed light on the underlying research assumptions, and enable more transparent monitoring of data quality and error. This can significantly increase the reach and impact of research, promote transparency, reproducibility, and open science, as well as improve the clarity and presentation of IE research. A review of current IV applications reveals that, while data exploration has received some attention among IE practitioners, IV applications in scientific communication are clearly lacking. With the help of a working example, we explore the value of IV, discuss its operationalization, and highlight challenges that the IE community must face during IV uptake. Such challenges include technical and knowledge limitations, limits on user interaction, and implementation strategies. With these challenges in mind, we outline key aspects needed to lift the IE field to the forefront of scientific communication in the coming years. Among these, we draft the basic principles of a “Hub for Interactive Visualization in Industrial Ecology” (HIVE), a point of encounter where IE practitioners could find an array of data visualization tools that are geared toward IE datasets. IV is here to stay, and its inceptive stage presents many opportunities to IE practitioners to shape its operationalization and benefit from early adoption.     

公众对园林绿地功能的认知及其对环境教育的启示——以广州市为例

以网络问卷和现场问卷、访谈的形式,分析公众对广州市园林绿地功能的认知情况,以期为环境教育场地的建设提供参考。结果显示,公众对于物种多样性和景观多样性的各项具体描述的认知情况都趋于一致,绝大多数公众认为绿地植被能发挥重要的生态功能,且公众的学历越高,其认知园林植物的欲望越强烈。在休息时,大多数公众会选择植物比较茂密的半开敞空间;在园林设计中通过增强科普信息获取的便利性和趣味性,能更好地发挥绿地的环境教育功能。     

Comparative expression analysis of heavy metal ATPase subfamily genes between Cd-tolerant and Cd-sensitive turnip landraces

The heavy metal ATPase(HMA)subfamily is mainly involved in heavy metal(HM)tolerance and transport in plants,but an understanding of the definite roles and mechanisms of most HMA members are still limited.In the present study,we identified 14 candidate HMA genes named BrrHMAl—BrrHMA8 from the turnip genome and analyzed the phylogeny,gene structure,chromosome distribution,and conserved domains and motifs of HMAs in turnip(Brassica rapa var.rapa).According to our phylogenetic tree,the BrrHMAs are divided into a Zn/Cd/Co/Pb subclass and Cu/Ag subclass.The BrrHMA members show similar structural characteristics within subclasses.To explore the roles of BrrHMAs in turnip,we compared the gene sequences and expression patterns of the BrrHMA genes between a Cd-tolerant landrace and a Cd-sensitive landrace.Most BrrHMA genes showed similar spatial expression patterns in both Cd-tolerant and Cd-sensitive turnip landraces;some BrrHMA genes,however,were differentially expressed in specific tissue in Cd-tolerant and Cd-sensitive turnip.Specifically,BrrHMA genes in the Zn/Cd/Co/Pb subclass shared the same coding sequence but were differentially expressed in Cd-tolerant and Cd-sensitive turnip landraces under Cd stress.Our findings suggest that the stable expression and up-regulated expression of BrrHMA Zn/Cd/Co/Pb subclass genes under Cd stress may contribute to the higher Cd tolerance of turnip landraces.
