Towards lower carbon cities: urban morphology contribution in climate change adaptation strategies

Non-urbanized areas (NUAs) play an important role in reducing the effects of climate change by providing both carbon storage and sequestration. Urban areas are responsible for the emission of 60% of global greenhouse gas, 50% of which are produced by buildings. During the past decades, increasing urban growth and sprawl processes produced several urban layouts characterized by different morphological features and a common lack of sustainable energy and environmental solutions. Investigating the relationship between urban morphology, energy demand and carbon emission/sequestration represents a relevant topic for urban planning practices implemented to face urban climate change effects. This study proposes a method for a transformability assessment aimed at investigating the transformation suitability of different urban morphology types. The case study is the metropolitan area of Catania (Italy), characterized by an impressive urban growth since the 1960s. The proposed method identification of limits and options for increasing sustainability of urban areas considering the contribution of both NUAs and built-up areas. This approach allows to identify appropriate planning tools for new layouts of urban fabrics while increasing the objectivity of the decision process. In the framework of climate change mitigation and adaptation, the outcomes of this research may lead to innovative urban planning practices.     

Residential location,workplace location and car driving in four Norwegian cities

Based on a study in four Norwegian cities (Oslo, Stavanger/Sandnes, Bergen and Trondheim) differing in size and centre structure, this article illuminates how residential and workplace location, local-area density and transit accessibility influence different aspects of travel behaviour. We find strong effects of residential and workplace distance to the city centre on overall driving distances and commuting distances. We also find clear effects of local area densities around residences and workplaces on the choice of car as a travel mode, along with less pronounced effects of the distance from dwellings and workplaces to the city centre. In the cities with the best developed transit provision, we also see clear effects of transit accessibility at the residence on the propensity of choosing the car as travel mode. The results provide strong support of Norwegian national policies of urban densification as a planning strategy to curb the growth in urban motoring. However, although the influences of urban structure on travel show many similarities across the four cities, there are also important differences reflecting variations in centre structure (predominantly mono- or polycentric) and population size. The magnitude of the influences of various urban structural characteristics on travel behaviour are thus highly context-dependent.     

Pram mobilities: affordances and atmospheres that assemble childhood and motherhood on-the-move

The child-friendly city advocates for children's ‘right to the city’. Much of this advocacy focuses on the independent child, with little attention paid to the accompanied experiences of younger children, such as those travelling in prams. This paper draws on a material feminist perspective to help address this gap. We offer the concept of mother–child–pram assemblage to bring to the fore the corporeal dimensions of everyday pram journeys. By analysing sensory ethnographic materials collected with mothers and young children living in Wollongong, Australia, this paper highlights how the ‘affective affordances’ and ‘affective atmospheres’ of pram mobilities shape urban experience by reference to how motherhood and childhood are achieved on-the-move. We conclude with policy-relevant insights for the child-friendly city.     

New Philadelphia: using augmented reality to interpret slavery and reconstruction era historical sites

Does a historical site lose its significance or become less worthy of interpretation if there are no surviving buildings? Can technology help present the stories of disadvantaged and disenfranchised groups whose heritage lacks well-preserved architecture or material culture? The emerging technology of augmented reality (AR) offers new ways of designing and shaping the public’s experience when visiting landmarks by enabling an unprecedented means to combine 3D historical visualization with historical landmarks. This especially applies to underrepresented groups whose heritages have not been well served by traditional modes of preservation and interpretation due to a variety of factors. These range from disadvantages relating to material culture to a greater emphasis on intangible heritage which have placed them outside the bounds of what archaeologist Laurajane Smith calls authorised heritage discourse. A project at the New Philadelphia National Historic Landmark, located in Pike County Illinois, seeks to address these issues through AR. The technology, while offering opportunities for historical interpretation, poses challenges in terms of designing AR systems that coordinate content presentation with specific locations as well as developing virtual historical content with varying levels of source materials.     

基于快递物流测度的区域流动空间特征——以江苏省为例

在信息技术推动下,流动空间作为新时期的新空间形式在带来时空压缩效应的同时不断地强化着区域城市间联系,推动着社会经济资源的城际流通。快递物流是互联网交易的虚拟流与快速交通实体流交互产生的物质流动,其代表了流动空间的虚实二元性,是研究流动空间网络特征的有效切入点。以江苏十三个城市为研究区域,以六家物流公司的网站数据为数据来源,采用权重分析法和重力模型方法建立起区域城市的快递物流水平、城市间流动空间连接度及城市快递物流总体评价等三项指标,结合区域流动空间的指标分析发现区域流动空间具有网络一体化、去中心化、扁平化、等级化及点轴式等五大特征,基于流动空间的可视化研究发现江苏省区域城市间关系显示出了一个具有等级特征的多中心扁平化点轴网络,围绕南京、苏州、徐州的都市圈一体化发展态势成为提高区域流动空间流动能力的重要突破方向。     

清末两级地方自治中的官治与自治模式

清末地方自治包括府厅州县和城镇乡地方自治两个层级,并建构了两个层级不同的官治与自治模式,即在城镇乡一级实行"以自治辅助官治",而府厅州县则实行"自治与官治合并"之制度。两种模式都借鉴了日本自治制度,但都有所不同。就清末城镇乡地方自治的运行来看,由于地方自治章程赋予官府监督自治之权,也由于自治团体为谋求地方利益,常常也会与官府对立,所以,官治与自治常常处于矛盾冲突之中。     

The Awkward Squad: Arts Graduates from British Tropical Africa Before 1940

ABSTRACT

Before the Second World War, most Africans from British Tropical Africa who studied abroad were seeking qualifications in three professions: law, medicine and the Church. In all these, they could be reasonably sure of employment on their return. True, government employment was problematic, but law and medicine did offer the alternative – often more lucrative – of private practice. Much more threatening to colonial authority were arts students: those who read philosophy, literature, politics or sociology. This article focuses on several men who graduated in Britain or the USA: Kobina Sekyi, J.B. Danquah, James Aggrey, Bankole Awoonor-Renner (Gold Coast); Eyo Ita, Nathaniel Fadipe, Nnamdi Azikiwe – and his (mostly Igbo) protégés (Nigeria); Hosea Nyabongo, Balamu Mukasa, Ernest Kalibala (Uganda); Peter Koinange (Kenya). It concludes by surveying the career of Nicholas Ballanta-Taylor (Sierra Leone), who studied music in New York and in 1927 won a fellowship from the Guggenheim Foundation for musicological research in Africa. Of these pioneer African Africanists, four wrote successful doctoral theses, Azikiwe published an academic study. Aggrey and Fadipe died prematurely. Danquah applied his intellect to essentially non-academic pursuits. Ballanta, worked as a practical musician in the 1930s, but his African research remains virtually unpublished.     

Overcoming barriers to institutional integration in European second-tier urban regions

Within the debates about the socio-economic advantages of cohesive urban regions, several barriers to institutional integration are said to exist, especially when a metropolitan government is absent and integration relies on inter-municipal cooperation. Some barriers are associated with different urban region structures, such as the asymmetric power relations and sociocultural contrasts between municipalities in systems with dominant core cities, or the lack of a leading city to overcome fragmentation and provide a shared identity in polycentric urban regions (PURs). This paper investigates whether urban regions formed around second-tier cities, whose features depart from both dominant core and PUR models, are able to mitigate these barriers when pursuing integration strategies. The analysis relies on interviews with municipal leaders in three representative European case studies, examining how they perceive the barriers to inter-municipal relations in second-tier urban regions. The findings show that perceptions vary not only between regions, with the three cases following different trajectories of integration, but also within regions, according to the geographical and socio-economic context of municipalities and the legacy of past relations. In general, barriers to integration are not minimized without explicit efforts to rebalance power relations, approach political cultures, mobilize core city leadership and develop a metropolitan identity.     

Eyes on the alley: children’s appropriation of alley space in Riverdale,Toronto

ABSTRACT

Recent research suggests that numerous positive physical, cognitive, and social benefits can be derived from independent mobility and play agency amongst children, necessitating an understanding of how physical and social environments facilitate this development. This study involved parents, and children aged 9–13 from twelve households in the neighbourhood of Riverdale in Toronto. Using a mapping exercise to instigate discussion, participants were asked to describe where, how, and with whom play occurs in their neighbourhood. A reoccurring theme emerged amongst households that border a back alley where parents perceived this space as safer allowing them to grant greater independent mobility to their children and use this space as an intermediary tool to prepare their children for greater independence. For children, this space serves as one of creative appropriation, granting them access to more space and friends to play with. Situated within the context of age-friendly cities, this research identifies several socio-spatial qualities found in alleys that have the potential to contribute to the discussion of more inclusive city-building practice.     

British Policy Towards Military Cooperation with the Republic of South Africa, 1961–1975

The early 1960s were a turbulent time in South Africa; the Sharpeville Massacre provoked condemnation from the international community, which, with the acceleration of decolonisation, was turning increasingly against Pretoria. The decision to withdraw its re-application to the Commonwealth in October 1960 further isolated South Africa. Despite this, UK–South African military cooperation remained largely unaffected until the pivotal Simonstown Agreement's termination in 1975. This article explores this relationship and explains why British policy-makers consistently maintained links with an overtly racist regime. UK–South African military cooperation was persistently controversial and engendered frequent criticism from African members of the Commonwealth and from campaigning groups such as the Anti-Apartheid Movement, whose membership included Labour ministers. Concurrently, Pretoria was viewed as an important Cold War ally, particularly in the context of the build-up of Soviet naval incursions into the Indian Ocean from 1968 onwards. This article will analyse how British officials attempted to navigate its military relations with South Africa under such heated circumstances.
