当代美国住宅的思考

美国2000年新建住宅投资4251亿美元，占固定资产投资的21．3％；住宅直接消费为9588亿美元，占GDP的9．71％；年存量住宅为1．16亿套(户)，空置率为5．9％。购买新房一般中值价为80美元／ft^2，一套住宅(2000ft^2)中值房价为16万美元；按中值计算贷款购房的支出与收入比为1：4．7；在美国仍有3500万户居民租用住宅。

Developing Technological Stance: Children's Learning in Technology Education

Following a review of current research in children's learning in technology education, and an examination of the kinds of knowledge demanded in contemporary technology education programs in elementary schools, I argue that what is needed in early technology education programs is the scaffolding of what I am calling technological stance. This construct acknowledges the socio-cultural character of technology as a human endeavor. In contrast to programs which are oriented to application of conceptual and procedural knowledge or to programs in which knowledge is generated through interpretation of interactions with materials and tools, programs which support technological stance position learners as critical inquirers into both tool-related and discursive practices of technology.     

Enhancing Practicing Primary School Teachers' Pedagogical Content Knowledge in Technology

This paper describes the frameworks and cognitive tools that have been developed to enhance practising teachers' pedagogical content knowledge in primary school technology education. The frameworks evolved from our research that firstly examined existing teaching practices, secondly enhanced formative interactions and thirdly enhanced summative assessment strategies. The evidence gained over the three years demonstrated how the effective use of frameworks could be utilised to enhance teacher pedagogical content knowledge (PCK). How we see learning is of prime importance in examining the development of teacher pedagogical content knowledge. A sociocultural view of learning is taken where human mental processes are situated within their historical, cultural and institutional setting. In the research project we strongly emphasised the need for teachers to build a knowledge base for teaching technology. Critical aspects identified as enhancing PCK included: negotiated intervention, planning frameworks, reflection on case studies, workshops and support in classrooms, appropriate resources, teacher agreement meetings, portfolios of student work and summative profiles. The increased PCK resulted in: enhanced teacher knowledge about technology including the nature of technology, areas of technology and specific technological knowledge, changed pedagogical approaches, enhanced teacher student interaction, refinement of appropriate learning outcomes, critical decision making, improved teacher confidence, and enhanced student learning. Seven characteristics or features of pedagogical content knowledge that we believe are important for effective teaching and learning in technology are presented.

企业ESG 履责的绿色生产力效应研究——基于绿色技术创新视角

论文选取2011-2020 年沪深A 股上市公司为研究样本,基于绿色技术创新视角,实证研究了企业ESG 履责的绿色生产力效应。研究发现,ESG 履责显著促进了企业绿色技术创新水平;机制检验发现,企业ESG 履责主要通过缓解财务约束,提升企业声誉,以及提高企业信息披露质量,促进绿色技术创新水平的提升;进一步基于“宏观——中观——微观”的多维异质性检验显示,当企业所处环境规制压力较高、所在行业竞争压力较大、以及企业人力资源基础较好时,ESG 对绿色技术创新的促进效应更为凸显。论文研究对新形势下构建绿色生产力体系、助力实现新质生产力发展提供有益启示。

导游人员职业权益维护及其利益表达

我国导游员队伍建设出现的矛盾和问题归根结底在于导游人员职业权益的长期缺位,现实表现在三个方面:一是旅行社企业内、外部及境外同行都存在随意侵害导游人员工作岗位行政许可独占权;二是导游人员劳动报酬权、社会保障权难以保障;三是导游人员学习培训权难以维护.导游人员职业权益维护重在措施落实到位,更在于建立健全导游人员利益表达机制.具体措施主要有加强导游总量控制、旅行社企业等级标准与拥有导游队伍情况密切挂钩、旅游者(团)接待档次与陪同导游等级水平相匹配等;拓宽导游人员利益表达渠道则主要靠政府及其部门、导游群体代言人、工会组织、社会舆论监督、旅行社企业社会责任标准认证和民间团体等社会各个方面共同发挥作用.
