随着工业化和城市化进程推进,小城镇居住区的低碳节能规划设计关系到城市发展和人们生活健康。考虑低碳节点效果,提出一种基于二氧化碳含量和温度自回归分析的小城镇居住区规划设计模型。模型设计包括了城镇的楼宇建筑设计、绿化景观和风景园林设计等。通过可持续发展的建筑规划选址、合理的土地利用、适宜的功能分区、安全便捷的交通系统等子系统设计完成居住区的整体规划。采用功能分区合并技术,把绿地系统分自然绿地、居住绿地、活动绿地、庭院绿地。规划区域主要分为生活区和活动区、绿色生态区、商业区等四大区域,以光照、温度、湿度和绿化植物的碳吸收和释氧量为自回归参数进行数学建模。充分利用的南向采光和立体采光,使得居住区的光照强度增加。仿真实验结果得出,该模型具有较好的低碳节能效果,居民满意度提高。  相似文献

针对在我国高校毕业生就业流动特征的影响因素进行了相关的实证研究和讨论,研究表明高校毕业生的就业流动特征已经不是简单地遵从于他们的主观意志,而是和多种复杂的因素联系在一起的,其中家庭的地域因素显著地影响着高校毕业生的就业选择。  相似文献

The Master of Science in engineering technology: biochemical engineering is organised in KU Leuven at four geographically dispersed campuses. To sustain the Master's programmes at all campuses, it is clear that a unique education profile at each campus is crucial. In addition, a rationalisation is required by increased cooperation, increased exchange of lecturers, and increased student mobility. To achieve this, a multicampus education system for the M.Sc. in engineering technology: biochemical engineering was developed by offering modules that are also available for students of other campuses. Such a module is primarily based on the research expertise present at the campus. In the development, special attention has been given to the optimal organisation of the modules, evaluation, required modifications of the current curricula, and the practical consequences for students following the module at another campus. Even in the first year of implementation, around 30% of the students followed a multicampus module, which indicates the potential success of the multicampus concept described here.  相似文献

This paper is concerned with the twinning of sustainability with priorities of economic neoliberalization in education, and in particular via the mobility or diffusion of education policy. We discuss the literature on policy mobility as well as overview concerns regarding neoliberalism and education. The paper brings these analyses to bear in considering the uptake of sustainability in education policy. We ask to what extent sustainability as a vehicular idea may be twinning with processes of neoliberalization in education policy in ways that may undermine aspirations of, and action on, environmental sustainability. Toward the end of the paper, we draw on data from an empirical study to help elucidate how the analytic frames of policy mobility can inform our analyses of the potential concerns and possibilities of sustainability as a vehicular idea. In particular, we investigate how sustainability and related language have been adopted in the policies of Canadian post-secondary education institutions over time. The paper closes by suggesting the potential implications of the proceeding analyses for policymakers, practitioners, and researchers concerned with sustainability in education policy.  相似文献

The increasing number of people studying abroad has drawn significant scholarly attention to the experiences of international students. While these works have productively informed policy and practice regarding how international students may be better supported, they have not always considered the active ways international students contribute to higher education. This article suggests that adopting the notion of experience as a conceptual starting point is problematic because it only partially illuminates international students' agency and reproduces understandings of them as a vulnerable group. The more active notion of practice, by contrast, suggests a more agentive subject who is a pivotal actor in spaces of education. The main argument in this article is that the abiding focus on international students' experiences will be productively unsettled by orienting attention to their practices and theorising the notion of practice in more fluid and dynamic ways. After critically engaging with the existing literature, the article outlines four ways that a focus on international students' practices may reanimate debates. A focus on practice will: (1) show how international students actively contribute to spaces of higher education, including classrooms, campuses and other sites of sociality; (2) demand that researchers theorise agency in more expansive ways and consider the practices of a broader set of social groups; (3) encourage researchers to make use of a wider set of qualitative research methods; and (4) create a stronger political foundation from which to defend the interests of international students in a post-COVID-19 world.  相似文献

在产业结构优化升级和技术革新的挑战下,劳动者的技能和工作是否匹配具有重要的经济意义.通过2,476份北京市信息技术和养老护理等行业员工的调查问卷分析发现,超过三成的北京市劳动者技能不能满足当下工作所需;有12%的劳动者存在技能的落伍问题.利用序次和多分类逻辑斯特模型回归发现,相比于技能匹配的个体,技能不足对劳动者的工资收入、工作满意度和职业流动(跳槽)均产生了显著的负向影响;过度技能对劳动者的工作满意度和职业流动(跳槽)呈现明显的负向影响,且该影响效应高于技能不足的影响.对此,从关注劳动者技能"折旧"问题、倡导树立终身学习的观念等方面提出建议.  相似文献

   本文基于“科学家在线”平台数据,运用复杂网络分析方法,按照年份分别构建2010—2017年间全国34个省份之间科研人员流动网络模型,测度并分析8年间科研人员流动的复杂性网络整体特征和随时间变化的趋势。研究发现:(1)8年间科研人员流动呈现整体较为明显的“无标度”特性,即北京、上海、江苏等经济科技发达地区不仅流入科研人员的规模较大,流出科研人员的规模也不小,但是全国大部分省份流动科研人员规模较为有限;(2)除了小部分省份之外其余省份的人员流入流出相对较为均衡,一些经济科技发达省份在一定程度上也是全国或本区域科研人员流动的中心节点;(3)从发展态势来看,8年间全国省级科技人员流动态势相对平稳,但是省份之间科研人员流动规模差距越来越明显,经济科技发达省份与其他省份科研人员流动的规模相比差距越来越大;(4)最为突出的变化是流动人员规模显著增加,人员流动更加便利。  相似文献

Ice hockey requires rapid transitions between skating trajectories to effectively navigate about the ice surface. Player performance relates in large part to effective change-of-direction manoeuvres, but little is known about how those skills are performed mechanically and the effect of equipment design on them. The purpose of this study was to observe the kinetics involved in those manoeuvres as well as to compare whether kinetic differences may result between two skate models of varying ankle mobility. Eight subjects with competitive ice hockey playing experience performed rapid lateral (90°) left and right change-of-direction manoeuvres. Kinetic data were collected using force strain gauge transducers on the blade holders of the skates. Significantly greater forces were applied by the outside skate (50–70% body weight, %BW) in comparison to the inside skate (12–24%BW, p < 0.05). Skate model and turn direction had no main effect, though significant mixed interactions between leg side (inside/outside) with skate model or turn direction (p < 0.05) were observed, with a trend for left-turn dominance. This study demonstrates the asymmetric dynamic behaviour inherent in skating change-of-direction tasks.  相似文献
