城市化进程中城市新移民语言状况调查与分析

城市新移民在职业身份上多元混杂,希望得到迁移城市的文化和身份认可,而语言则是个人身份认同的外在表现。本文以杭州新移民(包括非白领移民和白领移民)为调查对象,采用问卷调查的方式研究他们语言使用和语言态度的情况。调查表明,在语言使用上,新移民随社交场合的正式程度及与交际对象的关系不同,呈现出普通话和家乡话并存分用的局面。在语言态度上,新移民对普通话存在较高的情感认同、地位评价和功能评价;对家乡话情感评价较高,但功能和社会地位评价较低,而对杭州话的评价正好与家乡话相反。     

以轨道交通支持天津市城市空间结构转化——天津市市域轨道交通系统规划

交通系统与城市空间结构是相互联系、相互推动的关系。轨道交通作为现代化、快速、大运量的客运系统,对城市空间演变发挥着重要作用。随着城市的快速发展,天津市的空间布局面临着重大转变。天津的市域轨道交通系统规划,以城市空间发展战略为依托,以积极引导天津市空间结构转化为目标,规划构建包括市域线及城区线两级线网、全市域联网互动的轨道交通网络。

Predictors of high-risk alcohol consumption in young offenders on community orders: Policy and treatment implications.

The present study examined the relationship between a set of individual and contextual variables and high-risk alcohol use among young offenders placed on community orders in New South Wales, Australia. Participants (n = 777) were compared on a set of factors known to be strong predictors of high-risk alcohol use among adolescents. The authors assessed the strength of the relationship between gender, age, ethnicity, geographical region of residence, school attendance, father absence, history of childhood trauma, and the presence of severe conduct disorder on weekly levels of alcohol use. Living in rural locations, not currently attending school, being female, and not having been raised with a biological father present were associated with significantly increased odds of alcohol abuse. Father absence was a more important risk factor for rural young offenders, but school dropout was associated with more hazardous drinking among young offenders in urban areas. Accordingly, the authors suggest family-focused intervention programs for young offenders living in rural areas and school-based programs for vulnerable young people living in urban areas, although programs should consider including both factors for both groups if feasible and warranted.

当代城市文化背景下的城市功能再生——另一种生态建筑

本文从现代城市文化的角度着手深入探讨了影响城市功能再生的诸多深层社会因素，指出城市功能的再生便是城市文化的再生，城市文化的再生便是城市人文精神的重塑，建筑学意义上的现代城市人文的重塑便是现代城市人对自身生存空间的心理归属，指出存在于现代建筑空间中的另一种生态体系——心理生态，进而提出基于非物质基础上的另一种生态建筑概念.     

Rural industrialization and environmental disamenities: the case of the Bendel cement company,Okpella Bendel state (Nigeria)

This paper attempts a comparative analysis of the economic and non‐economic damage of rural industrialization to the environment of a poor community in a developing country. The major finding is that rural industrialization is more directly and strongly associated with environmental disamenities than with economic loss. A policy implication of this is that the package of rural industrialization strategy in developing nations must transcend conventional compensation schemes. The package must include programmes to provide for alternative sources of water, say, and an adequate health care delivery, where the disamenities caused are in the forms of polluting natural sources of water supply and/or increasing health hazards.     

Groundwork – a case study in landscape and amenity management

The Groundwork trusts have now been in operation for well over a decade and have implemented a wide range of projects across England and Wales. The origins and purposes of Groundwork are traced, and an overview of the types of project undertaken is presented. The relationship of the trusts to public and private sector funding, and the kinds of partnership involved, are examined. Many successes have been achieved in landscape renewal, although there have been some frictions with local authorities, and it is still difficult to make objective assessments of value for money or performance across a wide range of criteria. Nevertheless, the network of Groundwork trusts looks set to continue to offer a broad and flexible approach to environmental management.     

Bennett house: Aboriginal heritage as real estate in East Perth

Abstract

As the mansions materialised in refurbished East Perth on the Swan River, a battle between the East Perth Redevelopment Authority and Perth's indigenous community over a land swap culminated in demolition of a heritage building significant to the Stolen Generations. This case study unravels the complex relations and practices underpinning Bennett House's demolition, resonant of other planning decisions involving Aboriginal sites in Western Australia.     

利用回归和人工神经网络预测城市雨水径流总磷模型的有效性

利用人工神经网络(ANN),探讨在不无监测系统的集水区城市降水质量预测的适用性.预测使用常规的气候和地理数据集,通过构建背景传播的神经网络和回归联合模型,克服利用逐步回归的方法对数据进行分析时违背独立数据假设的问题.研究通过交叉验证用于确定停止降水时间为输入变量参数,利用地区平均浓度(EMC)作为独立的变量,构建的模型比用负荷量构建的模型更精确.数据域和输入变量的选择对回归模型的准确性也有较大影响.但计算效率、动量和隐节点数目的选择等因素,对人工神经网络模型准确性的影响较小.同时,回归和人工神经网络模型的降水质量预测结果十分相似,但在不无监测系统的集水区域城市降水质量的预测方面,回归模型更有实效性.
