南京江北新区新型城镇化发展质量评价与提升路径

文章构建了由31项指标组成的新型城镇化综合发展质量评价指标体系,运用AHP层次分析法和熵值法,选择19个国家级新区中2018年经济总量排名前十的新区进行定量对比分析,并结合民生幸福建设群众满意度问卷调查分析,对南京江北新区新型城镇化发展质量进行综合评价。研究表明:(1)南京江北新区新型城镇化整体发展处于中上游水平,与发达新区相比存在一定差距,产业结构亟需优化;(2)发展增长方式、资源利用率、环境保护类指标明显落后;(3)科教文卫、居民生活等指标具有比较优势。文章最后提出新型城镇化提升路径为加快生态环境和公共服务建设,积极提升科教和生态示范效应,做大做强主导产业,促进城乡特色均衡发展和推进以人为核心的新型城镇化。     

Tourism agglomeration and urbanization: empirical evidence from China

Tourism-driven urbanization presents a new way of exploring the construction of a new-type of urbanization. Consequently, the relationship between urbanization and the frequent agglomeration of tourism activities has attracted much research attention in recent years. This paper empirically investigates the influence of tourism agglomeration on urbanization using China’s provincial panel data for years 1999–2012. A panel data model with a fixed effect model and a two-step system generalized method of moments estimation is constructed to explore that influence. Results show that tourism agglomeration positively influences urbanization, and there exists a U-shaped relationship between these two variables. After capturing the dynamic nature of urbanization, we estimate the long-term tourism agglomeration elasticity in China as 0.4566. This paper provides theoretical and practical implications on urbanization of China in view of tourism agglomeration.     

阐述如何加强道路桥梁施工监理

通常,道路桥梁的施工难度较高,其中涵盖的内容较多,如技术管理、预算管理、成本控制等。这些因素使道路桥梁的施工变得更为困难,施工的复杂性和综合性更加突出。在桥梁的施工过程中,存在着许多风险,所以需要做好施工监理工作,从而最大限度地保障施工过程中不会出现任何故障和问题。因此,加强道路桥梁施工监理至关重要。论文从道路桥梁施工的角度,探究和分析如何做好相关的监理工作。     

Gender and age distribution of motorcycle crashes in Spain

This study analysed motorcycle crashes in Spain. Ninety-nine thousand three hundred and four motorcycle crash reports filed in the years 2006–2011 were extracted from the Directorate General of Traffic database of crashes with victims. These data were analysed in terms of gender, age groups, trip purpose, type of crash, speed violation, day of the week, harm caused, use of helmet and psychophysical conditions of the driver to study the characteristics of motorcycle crashes in Spain and to assess the differences between male and female motorcycle drivers in these crashes. Significant differences were found in all the variables considered in the study, which implies gender differences in the profile of the injured motorcycle driver. The severity of motorcycle crashes suffered by male drivers is higher than that of women. These results corroborate the need to develop measures differentiated by gender, based on their profile.     

Opportunities to reduce road traffic injury: new insights from the study of urban areas

Abstract

Over the past four decades considerable efforts have been taken to mitigate the growing burden of road injury. With increasing urbanisation along with global mobility that demands not only safe but equitable, efficient and clean (reduced carbon footprint) transport, the responses to dealing with the burgeoning road traffic injury in low- and middle-income countries has become increasingly complex. In this paper, we apply unique methods to identify important strategies that could be implemented to reduce road traffic injury in the Asia-Pacific region; a region comprising large middle-income countries (China and India) that are currently in the throes of rapid motorisation. Using a convolutional neural network approach, we clustered countries containing a total of 1632 cities from around the world into groups based on urban characteristics related to road and public transport infrastructure. We then analysed 20 countries (containing 689 cities) from the Asia-Pacific region and assessed the global burden of disease attributed to road traffic injury and these various urban characteristics. This study demonstrates the utility of employing image recognition methods to discover new insights that afford urban and transport planning opportunities to mitigate road traffic injury at a regional and global scale.

‘We Live on Estimates': Everyday Practices of Prepaid Electricity and the Urban Condition in Maputo,Mozambique

This article examines the transition to prepaid electricity happening in Maputo, Mozambique, in order to reflect on the contemporary geographies of urban energy infrastructure and urbanization in sub‐Saharan Africa and other cities of the South. The article draws on fieldwork and archival research conducted in 2013 and 2014, arguing that prepayment constitutes a productive juncture in the urban experience of electricity infrastructure in Maputo's postcolonial moment, not merely a neutral technology or a disciplining technique of government (as argued by some scholarship). The article examines the multiple rationalities implicated in the use of the electricity infrastructure via prepayment and the organization of urban life it engenders (and of which it is also a product) by focusing on the everyday practices surrounding prepaid electricity of urban dwellers in neighbourhoods where the ‘modern infrastructural ideal' may never be fully realized. As a result, it contributes to an understanding of the experience of urban energy in cities where ‘slum urbanism', uncertainty and provisionality are dominant aspects of the urban condition.
