THE LIMITS OF LOCAL INITIATIVES: A REASSESSMENT OF URBAN ENTREPRENEURIALISM FOR URBAN DEVELOPMENT

The concept of diaspora as an active agent in the making of transnationalism has been a subject of various interpretations and heated debates. This study examines the heterogeneous subethnic identities of the Chinese diasporas and their spatial manifestation, using Hong Kong as a case. With its colonial connections and strategic location, Hong Kong has functioned as a center of origin and destination in the transnational movement of the Chinese diaspora. The great spatial mobility demonstrated by the Hong Kong sojourners or their "refugee mentality," as it is known, is found to be deeply rooted in their subethnic identity in the nation. A systematic analysis of spatial data collected in 1961 and 1996 reveals an uneven geography of subethnicity polarized by the elite English and Shanghainese on the one end and the local Kejia people on the other end. Despite the processes of deterritorization and displacement, the great spatial mobility of the Hong Kong sojourners and the diasporic landscape they have created have remained effectively shaped by their place-based ethno-linguistic identities. The seemingly "ungrounded empire" of Chinese diaspora capitalism, in which Hong Kong has played a crucial part, has been based on preexisting place-specific conditions.     

Saigon from the diaspora

In the wake of reform in Vietnam and the end of the cold war, overseas Vietnamese are returning to their former homeland in increasing numbers. For most of the first generation in the diaspora, memories of wartime Saigon are now being augmented by a touristic experience of contemporary Saigon/Ho Chi Minh City. This essay asks how the co-presence of these differently spatialized and temporalized ways of knowing the city affects the production and consumption of images of Saigon in overseas Vietnamese communities in the West. Based on media ethnography carried out in Vietnamese households in Sydney, the paper argues that changes in the way Saigon is represented in overseas Vietnamese popular culture reflect a shift in the larger politics of diasporic identity. While narratives of exile and refugeehood remain potent forms of affective (if not instrumental) politics in overseas Vietnamese contexts, transnational forms of consciousness and identification are beginning to enter into diasporic public culture, albeit in a highly contested way.     

离散旅游研究进展及研究框架

离散旅游经常被认为是一种“回家”的形式,而随着交通与通信技术的发展,旅游活动变得愈发便捷,也愈发国际化,这些背井离乡、散居他国的群体回到故乡的旅游体验更为复杂和多样化。这个趋势使得离散研究开始在地理学和旅游学的领域迅速发展,离散群体的旅游行为成为学术界一个新的焦点,也同样逐渐得到旅游市场的重视。文章在对近20年的相关文献和已有实证研究基础上,从离散研究范式的演变入手,梳理了离散旅游的研究进展并归纳其研究视角：地方依恋为内在心理驱动,跨国主义为外在地理特征。结合其他学者研究,从离散旅游活动的空间性和旅游活动的参与者角度对离散旅游进行了界定与分类。重点分析了离散旅游的时空特征、离散群体的旅游体验以及这一细分市场对祖国旅游市场的影响。最后将离散旅游的概念引入中国,指出现有华侨旅游研究的不足,有针对性地构建了符合我国实际的研究框架,阐明我国发展华人华侨离散旅游研究的意义和重点。     

State‐led talent return migration programme and the doubly neglected ‘Malaysian diaspora’: Whose diaspora,what citizenship,whose development?

This paper questions the assumptions of ‘diaspora’, ‘citizenship’ and ‘development’ underlying diaspora strategies targeting a specific pool of overseas Malaysian ‘talent’ migrants. I examine the Malaysian state's discursive attempts to construct a carefully contained economic ‘diaspora'—the ‘Malaysian diaspora'—through its talent return migration programme. In this process, there is a portion of the ‘Malaysian diaspora’, especially non‐bumiputeras (sons of soil), who are doubly neglected and excluded: first, from access to full and equal citizenship (which arguably contributed to their emigration in the first place); and second, from eligibility and recognition to participate in Malaysia's talent return migration programme. However, recent political activism calling for electoral reform and overseas voting rights challenges state‐constructed visions of the ‘diaspora’ and their expected roles in advancing ‘development’. This paper concludes by highlighting questions raised by the Malaysian case, linking these explicitly to how diaspora strategies—as they have been conceived, practised and contested—challenge the broader Migration and Development paradigm.     

Coloring the Field: Gender, “Race,” and the Politics of Fieldwork

My experiences combining research and activism within the Japanese-Canadian community reflect a growing concern among feminist and anti-racist scholars with the politics of work among people marginalized by racism and sexism. This concern arises within a context where “other voices” are being heard, but the legitimacy of one individual or group to represent another is being challenged. Such challenges require that essentialism and naturalism be addressed politically and theoretically, a difficult irony given the need to utilize essentialist categories to address the oppressive conditions under which they emerged. To do so, a critical theory of political construction is required.     

Transnationalism,emotion and second‐generation social mobility in the Filipino‐Canadian diaspora

Through the case of Filipino‐Canadian youth experiences, this paper examines socio‐economic mobility among the children of immigrants in the context of transnational social fields and emotional engagements with the diasporic homeland. The Filipino‐Canadian experience is distinctive in terms of immigration patterns, settlement trajectories, policy frameworks and the historical and contemporary construction of ethno‐racial identities. Using educational attainment as a proxy for a wider process of social mobility, the paper shows that outcomes among Filipino youth have been anomalously poor. The explanations for this situation are multiple, but this paper draws particular attention to the ways in which negative emotional engagements with the Philippines as a diasporic homeland may shape self‐esteem and aspirations among Filipino youth in Canada and thereby play a role in social mobility.     

Engaging Diasporas for Development: a case study of Pitcairn Island

Diaspora engagement is a growing trend and many governments, international organisations and policy makers are increasingly focusing on the role of diaspora in development strategies for the homelands. Such policies are predominantly critical to island-dense regions such as the Caribbean and Pacific that have suffered high rates of outmigration during the postcolonial period. One such Pacific island is Pitcairn, a British Overseas Territory, and is the focus of this article. But while most of the literature focuses on the positive benefits of diaspora engagement, this paper examines the dynamics of diaspora (dis)engagement and (dis)affection. Each diaspora has a unique set of needs and capabilities based on its historical experience and the present realities of its countries of origin and destination. While much has been written celebrating the role of diasporas in development, diaspora have also shown themselves to have dual natures, with sometimes conflicting identities and allegiances. Based on analysis of a recent Pitcairn Diaspora Survey and ethnographic data, discussion in this paper reveals that the best intentions of engaging diaspora for development can be impeded by several factors including: (1) the complex nature of identity, place and politics; (2) difficult negotiations between past, present and future intentions of movers; and (3) shifting ‘roots/routes’ and boundaries of identification. Consequently, the paper aims to highlight the realities of settlement and relationships of diaspora space and subjectivity with the homeland.     

Migration‐as‐development repackaged? The globalizing imperative of the Singaporean state's diaspora strategies

Diaspora strategizing is becoming an important field of public policy in countries that seek to advance development through migration. Diaspora strategies present a way of complicating interpretations of development, as countries that represent different levels of development seek to mobilize diaspora networks nonetheless. While Singapore's diaspora strategies prioritize diaspora knowledge networks, it bears the stamp of the country's colonial history, postcolonial priorities and developmental state apparatus. We suggest that these factors result in a distinctive diaspora strategy characterized by a centralized and technocratic approach more similar to diaspora strategies found in emerging economies. Earlier research on diaspora strategies has been concerned with assessing successes or failures, but a more critical scholarship that questions the logics and outcomes of diaspora strategizing is emerging. We bring the Singaporean case into dialogue with four such critiques: first, the intellectual foundations of diaspora‐centred development; second, the hyperextension of state infrastructure for emigration and stakeholder alignment; third, the selective mobilization of the idea of diaspora; and fourth, the evidence base upon which diaspora‐centred development is predicated. Our goal is to further critical interrogation into the logics, efficacy and sustainability of diaspora strategizing. We situate our analyses in the international literature on diaspora knowledge mobilization.     

Radiometric dating of recent sediments: beyond the boundary conditions

Most mathematical models for radiometric dating of recent sediments are particular solutions of a unique physical problem: the advective?Cdiffusive transport of a particle-bound radiotracer within a sediment profile that undergoes accretion. Regardless of the particular assumptions about fluxes, sedimentation rates and the diffusion term, all models assume ideal deposition as a boundary condition at the sediment water interface, i.e. new radioactive input will be deposited above the previously existing material. In sediments with very high porosities, this assumption may be unrealistic, because a fraction of the incoming flux may penetrate rapidly through the connected pore spaces. This process will be referred to as non-ideal deposition. This paper reviews evidence from literature data, discusses the basic processes involved, and establishes the mathematical basis to incorporate non-ideal deposition into one-phase radiometric dating models, as depth-distributed local sources. Through analytical and numerical solutions, this work demonstrates that such penetration patterns can explain excess ²¹⁰Pb subsurface maxima, often observed in sediment cores, as well as penetration of ¹³⁷Cs to depths greater than expected from sedimentation rates and diffusion. These ideas are illustrated using examples from the literature in which sediment porosities were >90?%. Implications for radiometric dating include: (1) spurious accelerations in sedimentation rate inferred when applying the constant rate of supply model, and (2) erroneous chronologies, developed when using the maximum depth at which ¹³⁷Cs can be measured as a chronostratigraphic marker.     

'Dad says I'm tied to a shooting star!' Grounding (research on) British expatriate belonging

This paper analyses one British woman's everyday practices of belonging as she negotiates expatriate life in Dubai, United Arab Emirates. In doing so, it responds to widespread calls to ground research on processes of transnationalism and diaspora by drawing on 18 months of ethnographic research and adopting a three-stranded analytical framework to reflect on the significance of domesticity, intimacy and foreignness in expatriate belonging. The author focuses on a single research subject to draw attention to a particular British expatriate experience otherwise neglected in migration research and the paper resonates with theoretical literatures aiming to challenge the binary divisions of geographies of belonging, including attachment/detachment.     

Seismic waves in rocks with fluids and fractures

Seismic wave propagation through the earth is often strongly affected by the presence of fractures. When these fractures are filled with fluids (oil, gas, water, CO₂, etc.), the type and state of the fluid (liquid or gas) can make a large difference in the response of the seismic waves. This paper summarizes recent work on methods of deconstructing the effects of fractures, and any fluids within these fractures, on seismic wave propagation as observed in reflection seismic data. One method explored here is Thomsen's weak anisotropy approximation for wave moveout (since fractures often induce elastic anisotropy due to non-uniform crack-orientation statistics). Another method makes use of some very convenient crack/fracture parameters introduced previously that permit a relatively simple deconstruction of the elastic and wave propagation behaviour in terms of a small number of crack-influence parameters (whenever this is appropriate, as is certainly the case for small crack densities). Then, the quantitative effects of fluids on these crack-influence parameters are shown to be directly related to Skempton's coefficient B of undrained poroelasticity (where B typically ranges from 0 to 1). In particular, the rigorous result obtained for the low crack density limit is that the crack-influence parameters are multiplied by a factor  (1 − B )  for undrained systems. It is also shown how fracture anisotropy affects Rayleigh wave speed, and how measured Rayleigh wave speeds can be used to infer shear wave speed of the fractured medium in some cases. Higher crack density results are also presented by incorporating recent simulation data on such cracked systems.     

Regulating migration to Australia and back to the Philippines: Applying a ‘diaspora strategies’ framework

This paper examines circular labour migration between Australia and the Philippines by bringing Australian immigration policies and Philippine diaspora strategies under the same analytical framework. An extensive Philippine bureaucracy regulates migrants at each stage of the circular migration cycle, and as a sending state it has an interest in migrants staying temporarily in host countries such as Australia. The requirement to return home at the end of an overseas work contract compels migrants to remain attached to the sending state, their homeland, and return subsequently. However, Australia is allowing a route for temporary migrants to apply for permanent residency while in the host country. This has implications for sending states that rely on migrant ties to the homeland. The paper argues that analysing the intersections between the themes of migration, development and diaspora strategies reveals the multiple meanings of temporariness during migration and in migration studies. It questions whether associating temporariness with precariousness and marginalization is an accurate representation of the complex conditions underpinning circular labour migration.     

Crime concentrations and similarities in spatial crime patterns in a Brazilian context

Research within the geography of crime and spatial criminology literature most often show that crime is highly concentrated in particular places. Moreover, a subset of this literature has shown that the spatial patterns of these concentrations are different across crime types. This raises questions regarding the appropriateness of aggregating crime types (property and violent crime, for example) when the underlying spatial pattern is of interest. In this paper, using crime data from Campinas, Brazil, we investigate the crime concentrations and the similarities among different crime types across space. Similar to some recent research in another context, we find that crime is highly concentrated in Campinas but the ability to aggregate similar crime types at the street segment level is not generalizability when compared to a North American context.     

HYDROGRAPHIES*

ABSTRACT. Drawing on the work of the theoretical biologist Humberto Maturana, I offer in this essay a way of conceptualizing the forms of identity that survive the various death pronouncements of our postidentitarian moment. I associate the work of imagining those strange new forms of identity with what Frederic Jameson calls “cognitive mapping,” arguing that these “afteridentities” can emerge from a “hydrographic” charting of the fluid cultural territories of the modern and the postmodern. In conclusion, I indicate how this approach may be of use in contemporary attempts to “map” the diasporic territories of the Black Atlantic.     

Diasporic connections: case studies of Asian women in business

Fieldwork and Tropicality in French Indochina: Reflections on Pierre Gourou's Les Paysans Du Delta Tonkinois, 1936

This paper examines the fieldwork undertaken by the distinguished French geographer Pierre Gourou (1900–99) in the Tonkin Delta (Red River Delta) of northern Vietnam in the 1920s and 1930s, and his wider configuration of “the tropical world” as a distinct space of knowledge and radical otherness. Gourou's fieldwork endeavours in French Indochina are interpreted in the light of recent work on “tropicality”: the idea that “the tropics” need to be understood as a western cultural construction and colonising discourse that essentialised the hot, wet regions of the world, and exalted the temperate world over its tropical counterpart. The paper focuses on Gourou's monumental 1936 study Les paysans du delta tonkinois, étude de géographie humaine. It is argued that in this study, and his later comparative work on the tropics, Gourou elaborated a distinct geographical variant of tropicality, but one that, ultimately, reinforced the essentialist logic and momentum of this discourse. Particular attention is paid to the geographical ideas, fieldwork techniques and discursive strategies that Gourou used in his 1936 study, and the French colonial context in which he worked. The article shows how Gourou appealed to western reason and science as tools of study, identified overpopulation as the key problem facing the Tonkin Delta, and suggested that colonial practices of modernisation had a limited place and ineffectual role in the rice plains of the region.     

Learning and earning: relational scales of children's work

There is an important dissonance in recent studies of children's work between the global efforts to eradicate abusive forms of child labour on the one hand and, on the other hand, local settings where children's work plays an important role in social reproduction, socialization and skill acquisition. This research explores the reasons for this dissonance by eliding both the global perspectives of children's rights and the local realities of children's daily geographies. By closing the gap between global knowledge about children (from above) and children's knowledge and agency in their own environments (from below), we seek to present a relational account of children's work within the context of their daily geographies. We draw on data collected with child workers in Tijuana, Mexico to demonstrate the complex role that children's work often plays in the daily geographies of young people.     

Awkward geographies: Spatializing academic responsibility, encountering Sri Lanka

This paper responds to recent postcolonial geographical scholarship that sets forth transformative agendas in order to create more cosmopolitan theoretical projects within the discipline. For many geographers the challenges they face are located within not only their own disciplinary parameters, but also those of other specific research communities within which their work situates them. By bringing geography and area studies into productive conversation, this paper explores the tensions between negotiating one's academic voice, position and responsibility within geography as well as within a specific area studies community. More specifically, as a UK-based geographer I reflect on some of my own fairly unremarkable, yet extremely awkward, encounters during the course of scholarly praxis in Sri Lanka in order to raise questions over the spatialities of responsibility and political engagement in such academic praxis. I seek to theorize the chasms that open in such awkward encounters between notionally situated 'local' and 'foreign' scholars respectively and, in particular, develop ways of engaging and reorienting those chasms in ways that might enable the production of theoretically rich, yet richly contextualized postcolonial knowledges committed to the site of one's scholarly praxis – not just to the advancement of a more cosmopolitan theoretical project within geography.     

Diaspora strategies in the sending states of Southeast Asia: Rights,skills and questions of value

Over the past decade there has been a surge of academic and policy interest in the contributions of transnational migrants in furthering national development objectives in their ‘home’ countries. These approaches tend to be bifurcated into two distinct categories: (1) ‘diaspora strategies’ that target the participation in national development objectives of sought‐after elite, high‐skilled migrants and (2) migration‐as‐development strategies, which focus on facilitating and channeling the economic and social remittances of nonelite, low‐skilled migrants. Although these broad categorizations have never been entirely adequate in capturing the complexity of international migration flows, a conceptual division between them persists, with very real consequences for state policies in migrant‐sending countries in Southeast Asia. This paper explores the separation between diaspora strategies and migration‐as‐development frameworks through a focus on rights and skills, and questions of relative labour value. I argue that while diaspora strategies and migration‐as‐development frameworks cannot simply be merged, the academic separation between them should be challenged and more in‐depth theoretical engagement should be encouraged. I further suggest that migration policy makers should strive to evaluate their migration policies to address the increasing complexities of contemporary migration.     

Place,exile and identity: the contemporary experience of Palestinians in Sydney

Statelessness, displacement and exile, far from being particular moments in history, continue to affect the lives of Palestinians living in Sydney, in the maintenance of national identity and community formation. The impacts that displacement and subsequent ‘statelessness’ have had on the ways in which Palestinians maintain a sense of national identity have similarities with those of other ‘displaced’ peoples. Without the recognition of national boundaries to secure national sovereignty (Palestine) and accommodate the continuation of a shared and inherited history, the most significant element through which Palestinian identity is kept ‘alive’ is the one thing that all Palestinians share: a communal sense of injustice which involves being denied the right to live in, or return to, their homeland. Statelessness, nationalism and the now ‘imagined community’ of Palestine are more crucial for Palestinians living in Sydney than more primordial elements of identity, such as language or local community. Statelessness and exile in Australia have constructed a particular sense of Palestinian nationalism. The continuity of Palestinian identity as a primarily political phenomenon is a situation analogous to that of other diasporic refugee communities.
