Thermal treatment projects are presented as quick fixes for rising waste challenges, without addressing the limitations of incineration. Currently, there is a rise in proposals for thermal treatment technologies in developing countries. Scrutiny of the risks and impacts of these alternatives is necessary due to social, climate, and resource considerations. Energy from waste incineration is considered fossil energy since about half of the CO₂ emissions come from fossil polymers in the waste. From a sustainability perspective, landfilling is a short-term option for materials currently unsuitable for recycling. Landfills act as bioreactors, producing valuable biogas, and serve as “resource banks,” storing unrecyclable resources until better recycling techniques are developed. In developing countries manual labor is abundant and material sorting and landfilling are more valuable and have a lower climate and resource footprint.

Empirical analysis of the Tel Aviv-Jaffa 2008 municipal elections and their aftermath reveals that defining and engaging with a notion of the city's “ordinary people” can serve to further urban democracy. Four mutually reinforcing levels of transformative populism are identified: transformation of discourse, participation, rules of the game, and policy. The findings of this study suggest that democratically transforming discourse faces less resistance from local elites than transforming participation, the rules of the game, and policy.</div></div>","PeriodicalId":48405,"journal":{"name":"Cities","volume":"156 ","pages":"Article 105524"},"PeriodicalIF":6.0,"publicationDate":"2024-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142533468","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For emerging countries, this gap encountered during the development process should be addressed by promoting development, which also puts forward high requirements for economic management. Inspired by political economy theory and the widening urban–rural income gap in China, this study constructs a theoretical framework of “purpose-behavior-performance-structure” based on the urban bias theory, and then quantitatively examines the effect of economic growth target on the urban–rural income gap based on panel data at the provincial level. In addition, we explore the mechanism by which economic growth targets affect the urban–rural income gap with the mediating effect model, and investigate the impact of marketization and spatial structure on the relationship between economic growth targets and urban–rural income gap with the moderating effect model. The results show that the economic growth target significantly contributes to the widening urban–rural income gap in the face of the political promotion incentives and economic growth target accountability system, and this effect exhibits substantial spatiotemporal heterogeneity. In addition, fiscal expenditure, fixed asset investment, and labor mismatch under urban bias are important mechanisms that lead to the widening urban–rural income gap, and the marketization level and spatial structure significantly affect this relationship. We put economic growth management, urban bias, and urban–rural income gap into the “purpose-behavior-performance-structure” theoretical framework, which provides a new explanatory perspective for understanding the urban–rural income gap in emerging economies, and new policy insights for rational economic growth management.</div></div>","PeriodicalId":48405,"journal":{"name":"Cities","volume":"156 ","pages":"Article 105518"},"PeriodicalIF":6.0,"publicationDate":"2024-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142533462","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We estimate spatial Durbin models with street segment and census tract by year fixed effects to examine the effects of one measure of direct investment, building permits, on changes in crime at street segments and the extent to which such effects vary by census tract-level concentrated disadvantage, residential stability, median housing values, percent non-White, percent foreign-born, and population density. Findings reveal a significant negative relationship between permit activity and changes in crime in all cities. With few exceptions, effects were strongest among segments in the densest neighborhoods with the highest percentage of foreign-born residents where concentrated disadvantage is high and residential stability and median home values are low.

Social distancing restrictions brought into sharp relief the infrastructural dimensions of social care and support services and networks that are often backgrounded in day-to-day practice. A shadow care infrastructures lens looks purposively at care infrastructures that are not readily seen or acknowledged in dominant welfare discourse and research (Power, Wiesel, Mitchell, &amp; Mee, 2022). Taking this analytic lens as our starting point, in this paper we explore how relations of care were reconfigured by the shift to remote care delivery during Covid-19 lockdowns and beyond. The challenges of providing care during lockdown reveal the complex interplay between distance and proximity in care relations and practices and the possibilities for doing care differently. The paper draws primarily on in-depth interviews with paid and voluntary supporters across a diverse range of care organisations servicing two Local Government Areas (LGAs) in Central Western Sydney.

{"title":"Visualization of commuting areas and examination of jobs-housing balance with the adoption of excess commuting","authors":"Bing Sheng Wu,&nbsp;Tzu-Chi Chieh","doi":"10.1016/j.cities.2024.105541","DOIUrl":"10.1016/j.cities.2024.105541","url":null,"abstract":"<div><div>Rapid urban growth extends the boundaries of urbanized areas and makes people spend extra travel cost on the journey to work. Scholars have examined commuting behaviors between residence and work places within a region, and suggested the conceptual theory of jobs-housing balance to evaluate if there are sufficient job opportunities for residents in the region. A quantitative measurement of excess commuting is proposed to reflect the degree of jobs-house balance. However, current studies focus on the evaluation of excess commuting and the causality of spatial restructuring between residence and workplace, the spatial extend of excess commuting in an urban region is not visually delineated. In addition, conventional studies acquire static data such as statistic data or other survey data to analyze impacts of commuting patterns on urban formation. Today the emergence of spatial big data sheds light on the causality of urban commuting from higher spatial and temporal resolutions. This study aims to examine the degree of jobs-housing balance through the calculation of excess commuting and represent the spatial extent of excess commuting of Taichung metropolitan area in Taiwan. Electronic Toll Collection (ETC) data, the spatial big data which is publicly accessible in Taiwan, is introduced as the commuting data and to calculate three key parameters of excess commuting, T<em>min</em>, T<em>obs</em>, and T<em>max</em>. The three parameters are used to visualize the extent of commuting zones and examine commuting patterns of Taichung metropolitan area and observe the spatial relationship between those patterns and land-use types. The evaluation of excess commuting indicates that the degree of jobs-housing imbalance in Taichung metropolitan area is similar to Los Angeles metropolis in US. The analytical results explain how ETC data can be successfully used for the calculation of excess commuting, and visualization of the extent of commuting regions. In addition, after the cluster analysis of residential areas, it is intuitive to observe spatial correlation between hot zones of residential areas and the spatial extent of theoretical maximum commuting, and shows that the scenarios of commuting can be considered as an indicator to explain the possibility of urban expansion in the future.</div></div>","PeriodicalId":48405,"journal":{"name":"Cities","volume":"156 ","pages":"Article 105541"},"PeriodicalIF":6.0,"publicationDate":"2024-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142533391","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By distinguishing between pre- and post-COVID-19 periods and between commuting and non-commuting travel, this study reveals decreased average travel distances in the post-pandemic period and identifies factors influencing living radii, thereby favoring the concept of n-minute cities. During the post-COVID-19 period, the impact of factors such as population density, commercial facilities, and the job-housing ratio on travel distance has shifted, while neighborhood living and cultural facilities maintain consistent influence. This underscores the importance of prioritizing these aspects in n-minute city planning. Additionally, the mix of residential and business uses consistently affects shorter commuting distances, highlighting its critical role in n-minute city development.

Specifically, we first developed a transferable method that combined the Level of Traffic Stress (LTS) framework and graph theory to spatially quantify the quality of cycling infrastructure, and then used Hurdle models to examine the relationship between the presence of low-stress cycling infrastructure and cycling uptake across these cities. We found that while the majority of the roads in these cities are low stress, they are poorly connected, and the greater provision of low-stress cycling infrastructure is associated with more people cycling to work.
