Geographical Perspectives on Producer Service Industry Research in Australia

In contrast to the situation in North America and Europe, producer services research in Australia has largely focused on their international role rather than their domestic one. The growing internationalisation of the Australian economy in the last decade has been closely interrelated with the progressive internationalisation of producer service industries. International banking and finance as well as trade-related services have had significant urban impacts in major cities. Australia's growing linkages with East Asia are having impacts on the geography of service industries. However, little is known about the urban and regional implications of economic restructuring in these industries. There are important urban and regional implications resulting from the externalisation of services from manufacturing, as well as from the shedding of labour on the part of large service industry organisations. Similarly, little attention has been given to urban and regional implications of producer services by policy makers either at a federal or state government level.     

City networks: breaking gridlocks or forging (new) lock‐ins?

There is today a global recognition that we live in an ‘urban age’ of near‐planetary urbanization where cities are at the forefront of all sorts of agendas. Yet little attention is offered to the active role of cities as political drivers of the urban age. There might today be more than two hundred ‘city networks’ globally, with thousands of para‐diplomatic connections actively defining relations between cities, international organization and corporate actors. This actively networked texture of the urban age shapes all areas of policy and, not least, international relations, and holds much promise as to possible urban solutions to global challenges. Based on an overview of a representative subset of this mass of city‐to‐city cooperation (n=170), this article illustrates the landscape of city networking, its issue areas and institutional shapes, and its critical features. As we argue, city networks today are faced by a crucial challenge: while trying to overcome state‐centric ‘gridlocks’ cities are, at the same time, building both political–economic as well as very material ‘lock‐ins’. We need to pay serious attention to this impact of city diplomacy in international affairs, developing a greater appreciation of the path dependencies and responsibilities this diplomatic activity purports.     

Urban Form,Sustainability and Health: The Case of Greater Oslo

Several studies have shown dense urban structures to be favourable in order to reduce greenhouse gas emissions from transport, limit energy consumption in buildings and protect farmland and natural areas in the surroundings of the city. There may, however, be some tensions between such a compact urban developmental strategy and considerations of public health in urban planning. This paper reviews findings from international research on the relationships between urban form and health and illustrates some of these effects by comparing statistics on life expectancy and the frequency of heart attacks among inhabitants of different urban districts in the Norwegian capital Oslo. Since we have only had access to aggregate figures at the level of urban districts, the results must be interpreted with caution. The currently available results do, however, suggest that the densification strategies often recommended for reducing the ecological footprints of cities might be encumbered with some important drawbacks, seen from a public health perspective. Based on the findings, some dilemmas and perspectives for sustainability- and health-oriented urban planning are discussed.     

跨境流动背景下族裔社区研究进展及启示

随着全球化的不断推进，跨境流动成为一种常见的地理空间现象，塑造着城市空间和景观，同时作用于族裔社区及族裔经济等，由此带来的多元文化协商进而成为城市发展和城市治理的重要话题。本文通过梳理国内外关于跨境流动和跨国族裔社区的相关研究，发现：①国内外关于移民族裔的人文地理学研究仍较倾向于关注跨国空间的特征、演变以及脉络；②西方人文地理学界的移民或是跨国族裔研究已展现出较为鲜明的“文化转向”印迹，而国内的相关研究仍处于起步阶段；③中国城市族裔空间的研究仍以具体的描述性和解释性研究居多，多尺度、多地方的对比研究较为缺乏。研究立足于国内外移民研究进展，以期更多的跨境流动研究为城市综合治理提出“中国经验”。

Monitoring the Near‐surface Urban Heat Island in Beijing,China by Satellite Remote Sensing

Urban heat island (UHI) effect is an important impact factor of the regional climate and ecological environment. How to observe and analyse the spatial distribution of UHI has become an important issue of urban environmental research. In this paper, the near‐surface air temperature of Beijing was derived based on the Landsat/TM satellite imagery on 26 July 2011 to study the near‐surface UHI. A statistical model at 195‐m window size was established to estimate the air temperature, using land surface temperature, normalized difference vegetation index, altitude, and surface albedo as independent variables. The mean absolute error (MAE) of the model was 0.87°C, and the R² was 0.66, indicating that the method can be used to effectively estimate the air temperature. The air temperature distribution obtained from remote sensing revealed that the UHI effect in Beijing was very significant and showed a concentrated pattern. The heat island intensity was stronger in the southern part than in the northern part of the city. In addition, the relationship between the air temperature and impervious surfaces was analysed. The air temperature increased with increasing impervious surface coverage, and the rate of change depended on the impervious surface coverage. When the impervious surface coverage was below 40 per cent, the temperature increased rapidly with increasing impervious surface coverage, and when the impervious surface coverage was above 40 per cent, the temperature increased slowly. This study provides a new approach to monitor near‐surface UHI and reveals its relationship with impervious surface, providing a scientific reference for urban planning and environmental assessment.

Services sector in India: trends,issues, and the way forward

This paper provides an overview of the Indian services sector. It shows that services is the fastest growing sector in India, contributing significantly to gross domestic product (GDP), GDP growth, employment, trade, and investment. India is a major proponent of liberalizing services both in the World Trade Organization and in its bilateral trade agreements. However, there are some concerns. In the recent past, economic growth and growth of the services sector has slowed down. Growth in employment in services has not been commensurate with the share of the sector in GDP. Although India is a major exporter of services, its export competitiveness concentrates in few sectors and a few markets. The paper identifies a number of barriers faced by the services sectors and suggests policy measures which, if implemented, will lead to inclusive growth, increased productivity, generate quality employment, increase trade and investment, and enhance India’s global competitiveness in services.     

Le Conte de deux cités1 : Analyse comparative des conflits urbains de Montréal et Valence, 1995–2010

A tale of two cities: 9 Comparative analysis of urban conflicts of Montreal and Valencia, 1995–2010 Metropolization processes at work in contemporary societies produce social and spatial change, which can raise strong opposition from a variety of urban actors, leading to acts of dissent. While such urban conflict has been examined in the past, geographical analysis of urban conflicts as sociospatial processes is more recent. Systematic quantitative research on urban conflict is virtually nonexistent in terms of comparative analysis conducted with an international perspective. Systematic comparative analysis sheds light on the existing relationship between urban conflicts and the socio‐territorial contexts in which conflicts emerge and evolve. This article presents a comparative analysis of urban conflict that occurred in a selection of boroughs in two cities characterized by different geographical realities, Valencia (Spain) and Montreal (Canada), between 1995 and 2010. Spatial autocorrelation techniques applied to a conflict database show a significant relationship between the emergence of urban conflict and the spatial distribution of some contextual variables. Indeed, for Montreal as for Valencia, the concentration of urban conflict is the greatest in the most deprived neighbourhoods. Also, regarding the management and regulation of urban conflict, results shed light on important differences between Montreal and Valencia. These differences include the outcome of urban conflicts, repertoire of action of actors involved in conflict activity, and the type of contestation faced by actors who promote the challenged urban projects.

降雨和空气污染对城市居民公共自行车使用的影响研究——以西安市为例

公共自行车交通（以下简称公自）作为近年来快速发展的新型公共交通模式,逐渐成为国内外相关学科的研究热点。国内外大量学者探索了公自的使用特征及影响因素,但关注天气条件对公自使用影响的研究不足,来自中国城市的实证证据更是缺乏。本文以西安市为案例,利用西安市公自系统运营数据,探索降雨和空气污染对城市居民公自使用的影响。研究结果表明：①降雨和空气污染条件下公自使用规模减少,但降雨带来的影响大于空气污染。②降雨和空气污染条件下公自站点中平衡站点比例减少,且公自借出和归还为主站点的冷热点区域空间分布发生显著差异。③降雨和空气污染对公自使用强度有显著影响,一级站点数量明显减少,且降雨的影响大于空气污染。降雨条件下公自使用高强度站点中心化和沿走廊分布的空间特征弱化。但空气污染条件下,无显著变化。研究结果有助于准确评估降雨和空气污染对于城市居民社会经济活动的影响程度,也能为更准确的研究城市居民公自使用的影响机制提供参考依据。     

Airport delays and metropolitan employment

This study provides the first empirical assessment of the impact airline delays have on urban employment. While previous works have suggested that road congestion can slow down regional development, the influence of air traffic delays on metro‐level jobs has not been examined comprehensively. The present study uses a nine‐year panel of quarterly data, which covers passenger airline traffic and delays at airports across urban areas in the United States. The panel also includes data on total and industry‐specific employment at the metropolitan‐area level. Our empirical estimates of the impact of air traffic on total employment are comparable to previously reported measures in the literature. However, we find that service‐sector employment is less sensitive to air traffic than other studies suggested. We provide new evidence confirming that delays have a negative effect on employment, a finding that is robust to various specifications of our empirical model. Our results indicate that a 10 percent increase in the number of delayed flights leads to up to a 0.15 percent decrease in total and service‐sector employment, a 0.47 percent decline in leisure and hospitality employment, and a 0.7 percent reduction in the employment level of goods‐producing jobs.     

Historical Archaeology and the Recent Urban Past

This paper examines the ways in which international historical archaeologists have explored the recent past, in an effort to inform and contribute to contemporary debates about social identity and social inclusion. It is argued that the archaeology of the mundane and everyday can contribute to contemporary culture by creating a sense of community and developing social cohesion. Emphasis is placed upon the archaeology of the recent urban past and case studies are presented from New York, Sydney and Cape Town. The paper concludes that the study of the materiality of urban social life offers a powerful research tool for social scientists, and that archaeologists and heritage interpreters should make greater use of this form of evidence within the context of early 21st‐century urban regeneration schemes in the UK.     

The calm before the storm: A punctuated equilibrium theory of international politics

Research has shown that policymaking in numerous domestic policies, across a multitude of polities, systematically produces a pattern of change that matches Punctuated Equilibrium Theory (PET), characterized by many incremental and occasional dramatic changes. The field of International Relations (IR), however, has paid surprisingly little attention to PET, even though the same pattern of change is also found in international politics. This study attempts to fill this gap and explains stability and change in international politics based on PET. Specifically, we detail the dynamics behind this pattern of behavior, both at the domestic and the international level, as well as their interplay. The empirical section shows that different indicators of international politics, including troop deployments, foreign aid and international trade, follow a leptokurtic pattern of change, which characterizes Punctuated Equilibrium, and whereby changes in countries' behavior are generally incremental, representing periods of relative stability, and punctuated by large changes that dramatically overthrow existing policies. Moreover, our results indicate that policy outputs where greater friction is at play are more punctuated than those policies that cannot as easily or directly be managed. This study urges future research to further explore the dynamics of stability and change at the aggregate, international level.

Epilogue: Homegrown in PNG — Rural Responses to HIV and AIDS

ABSTRACT A three‐years‐long, multi‐sited, multi‐method study conducted throughout Papua New Guinea by the Institute of Medical Research revealed a staggering prevalence of sexually transmitted disease (STD) that threatens an already fragile political‐economy and health services delivery system. Logistics, methodological complexities, and political and especially religious sensitivities hampered conduct of such research. Extremely little HIV social research has been allowed to inform interventions or serosurveillance protocols. Well‐ intended but ill‐conceived international initiatives have promoted a normative AIDS paradigm that misconstrues HIV transmission risk, incites greater fear, increases stigma, and promotes anti‐condom rhetoric. This collection ‘HIV/AIDS in Rural Papua New Guinea’ presents a sustained series of ethnographically based accounts of rural responses. In this epilogue I situate the importance of those responses in a discussion of the great divide between the lived realities of HIV infection and AIDS related suffering on the one hand, and the discursive practices and policies of media, public health, international donors and NGOs on the other.     

When less was more: external assistance and the political settlement in Somaliland

The internationally unrecognized ‘Republic of Somaliland’ presents a case in which the domestic drivers of peace and development may be examined when aid and other forms of international intervention are not significant variables. The relative autonomy of its peace process offers an alternative perspective on post‐conflict transitions to that offered in the majority of the literature, which instead problematizes either the perverse outcomes or unintended consequences of international interventions in conflict‐affected areas. The purpose of this article is not to establish the salience of Somaliland's relative isolation in its ability to achieve peace and relative political order, as this is already documented in the literature. Rather, it explores the ways in which that isolation fostered mutual dependence between powerful political and economic actors for their survival and prosperity. It uses a political settlements framework to probe the implications of this dependence for western statebuilding interventions in post‐conflict situations. The findings present a challenge to orthodox assumptions about how states transition out of conflict, particularly that: greater vertical inclusivity necessarily strengthens a political settlement; effective Weberian institutions are a prerequisite of an enduring peace; and that external assistance is usually necessary to end large‐scale violence in developing states or to prevent a recurrence of the conflict.     

Urban pattern and land cover variation in the greater Toronto area

Recent epistemological shifts in environmental geography have created a space to consider the interactions between ecological and urban systems more seriously. While openness to thinking about urban ecosystems has increased in recent years, there remain fundamental gaps in our knowledge. For example, recent research has examined the impact of urban–rural gradients on ecological conditions, but major voids exist regarding the relationship between urban development patterns and land cover heterogeneity, particularly for new forms of urbanization. This article attempts to address some of these gaps by examining the relationship between urban pattern and land cover in the greater Toronto area (GTA). In particular, measures of urban pattern that reflect aspects of development density, grain and function, as well as socio-economic characteristics, are systematically analyzed in relation to land cover heterogeneity. The regression analysis shows that multiple components of urban development pattern and socio-economic conditions are correlated with vegetated land covers, while urban density variables are not related. These results indicate more detailed representations of urban pattern should be incorporated into future human–environmental interaction studies in cities.
