The use of rule‐based systems for modeling space‐time choice has gained increasing research interests over the last years. The potential advantage of the rule‐based approach is that it can handle interactions between a large set of predictors. Decision tree induction methods are available and have been explored for deriving rules from data. However, the complexity of the structures that are generated by such knowledge discovery methods hampers an interpretation of the rule‐set in behavioral terms with as a consequence that the models typically remain a black box. To solve this problem, this paper develops a method for measuring the size and direction of the impact of condition variables on the choice variable as predicted by the model. The paper illustrates the method based on location and transport‐mode choice models that are part of Albatross model—an activity‐based model of space‐time choice.  相似文献

This article attempts to analyse mapping practices at the intersection of geography, black studies and literary studies, in order to reassess the political and pedagogical possibilities of mapping under late capitalism. I turn to Toni Morrison’s novel Beloved to track black cartographic practices otherwise obscured or, as Katherine McKittrick writes, “rendered ungeographic”. The novel offers a hidden and unauthorised archive for the often clandestine geographic practices that make possible fugitivity from the mechanics of “slaveholding agro‐capitalism” and its ongoing legacy. As an unofficial archive of black geographic practice, Morrison’s novel might itself be thought of as a map: a contemporary mode of memorialising the depth of place, relation, and navigation—a depth no two‐dimensional map can accommodate. Finally, this article demonstrates the valuable interventions that black studies and black creative production can make within the subfields of critical cartography and critical geography.  相似文献

Post-Soviet transitions have prompted a search for new policy tools and methods of data collection. The shift from universal welfare provision under the Soviet system to targeted assistance and poverty monitoring has stimulated a new interest in the measurement of living standards and poverty lines. This has promoted the use of quantitative techniques and sample surveys (household surveys, in particular) as privileged tools for the collection of policy-relevant information. This paper contends that survey techniques have particular limitations as research tools in an environment where local level case studies are scarce and where a host of new socio-economic processes are creating fundamental shifts in the landscape of social provision, redistribution and employment. These limitations are illustrated by drawing upon a household survey conducted by the author in four villages from two regions in Uzbekistan, Andijan and Kashkadarya, between October 1997 and August 1998. The ambiguities surrounding five basic concepts, those of household, employment, access to land, income and expenditure are discussed in detail, as are the changes in their contents and meanings in the context of transition. The gender differentiated outcomes of current changes and their possible implications are highlighted throughout the text. The conclusion suggests that Uzbekistan finds itself at an uneasy juncture where the policies deployed to ‘cushion’ the social costs of transition may reach the limits of their sustainability. A more contextually sensitive approach to the mechanisms that generate new forms of vulnerability and the use of qualitative and longitudinal methodologies are essential to an adequate monitoring of further changes.  相似文献

Lewis Binford’s contributions to field archaeology have been largely ignored in favor of his many contributions to theoretical issues dominating the discipline of archaeology at the end of the twentieth century. We examine Binford’s excavation methods in southern Illinois in the early 1960s and demonstrate how his considered approach served to systematize large-scale site excavation procedures. He adopted the time-honored tool of the salvage archaeologist—heavy equipment—and unapologetically employed it in a fundamentally new way, proving it to be a tool that served the greater goals of archaeological research. We trace the development of field methods and theoretical approaches in two case studies of Illinois archaeology and demonstrate how Binford’s contributions have been incorporated or rejected by subsequent CRM researchers.  相似文献

Nutritional adequacy in North Korea (DPRK) has remained spotlighted since the famine crisis of the mid-1990s. Data from national household surveys facilitated by UN agencies primarily focus on children, with interviews of their mothers. No data are collected on men, or specifically on adults. Survey data on adult escapees in China or South Korea are not representative of conditions prevailing in present-day North Korea. This study focuses on adults’ physical wellbeing by regressing women's mid-upper arm circumference (MUAC) as a proxy measure on selected household data from the third DPRK nutrition assessment. The results—with sampling limitations qualified—showed that residence in the ‘rice bowl’ region and access to farmers’ markets contributed most to wellbeing; differences in gross nutrition, biological factors, household size and even educational attainment mattered little. Further, elites in the national capital were worse off than households in the remote northeast, where proximity to China has facilitated trade exchanges for survival needs. All these signal emergent changes in household coping mechanisms, possibly even in the status quo, in present-day North Korea.  相似文献

Public engagement is becoming increasingly common practice in archaeological projects, capitalizing on the interactions of field archaeologists with local communities as well as with the descendants of the people under study, in a variety of ways: from the use of social media to engaging the local public with onsite presentations and exhibitions. However, public engagement efforts are often less robust when archaeologists return to their home institutions, with most of the researchers’ time and energies spent fulfilling their academic duties. Interactions between archaeologists and their local communities — those closer to their home institutions — are often minimal, creating insular university departments. To secure a future as a vibrant, relevant field of research, archaeology must develop greater interest and skill in engaging with its neighbours both within and outside the academy. The study of past meals and foodways provides an exceptional avenue for public outreach, which in turn is further enhanced through fruitful collaboration among various university departments and museums. Here we present the results of the multidisciplinary outreach project ‘Eating Archaeology’, designed with the intention of building collaborations across disciplines and a new narrative with which to engage the public.  相似文献

Many studies in geography and other disciplines require data to be collected from human subjects. Survey techniques are routinely employed but as expense and time impose powerful constraints there is much interest in methods of making the data collection process as efficient as possible, particularly when the numbers of subjects involved are large. The surveys described here were conducted to collect data for a study of residential water use in Melbourne. A previous analysis of demographic. physical and economic data (Aitken et al., 1991) had revealed the need for additional data to be used in explaining variability in residential water consumption. A theoretical basis was established for the relevance of attitudes, habits and values to water use, and a survey was planned with the primary aim of measuring these psychological constructs. It was conducted in early 1991. and the water consumption of participating households was recorded over winter of that year. The survey instrument also targeted demographic and physical data relevant to water use in the home. Dillman's Total Design Method (TDM — Dillman, 1978) offers an integrated and detailed methodology for survey design. and it was from the TDM that most of the methods for these surveys were derived. The elements of Dillman's methodology most relevant to these surveys are those concerning the presentation of the questionnaire package and its distribution.  相似文献

This article addresses the intra‐household division of responsibilities among the Bisa and Mossi in south‐eastern Burkina Faso. Based on a detailed village study of the land use which revealed that women cultivated 31 per cent of all the land in 1997, gendered practices in household budgeting are investigated. Although the proportion of women’s own‐account agriculture suggests that they contribute substantially to household consumption, the majority of women maintain that they only help their husbands when contributing in areas that, ideologically, are his responsibility, for example by providing food and by paying school fees and materials. In this way, women keep within the norms of showing respect for the husband but, at the same time, they may press him to fulfil his obligations.  相似文献

Most studies that incorporate a gender dimension into the study of poverty or other development outcomes focus on the sex of the household head. This article argues that a headship analysis gives only a partial view of gender inequality since it does not take into account the position of women within male‐headed households. Drawing primarily on the Living Standard Measurement Studies for Latin America and the Caribbean, the authors present baseline indicators of the degree of gender inequality in asset ownership for the eleven countries in the region that have collected individual‐level data on asset ownership. Disaggregated data on asset ownership within households suggest that the distribution of property by gender is more equitable than a headship analysis alone would imply. But the degree of gender inequality also varies according to the specific asset and among countries. Further comparative work on asset ownership requires attention to the marital regimes governing property rights in marriage. Finally, the authors suggest how household surveys could be improved by standardizing the collection of individual‐level asset data across countries.  相似文献

The Canadian Government has committed to establishing a national network of Marine Protected Areas. Progress in the Salish Sea (Strait of Georgia) of British Columbia has been slow. Opposition by First Nations is a factor as these protected areas have the potential to impact on Aboriginal rights. This case study with the Hul’qumi’num First Nations examines their approaches to marine conservation and their perspectives on “no‐take zones” as a component of marine conservation. The study used a variety of community engagement procedures including relationship building, hiring of a Hul’qumi’num research assistant, conducting individual interviews, focus groups, and field surveys. Interviews were conducted with 41 participants contacted because of their knowledge and interest in marine resource use. The views reported provide a rich understanding of Hul’qumi’num attitudes, but cannot be generalised to the whole population. There was widespread support for efforts to involve local First Nations communities in the development of management plans for marine resources, and also for recognition of First Nation reliance on marine resources for food, social, and ceremonial needs and for economic development opportunities. The establishment of permanent no‐take zones was met with both opposition and support. The most highly endorsed statement about no‐take zones is one of principle—that they are a violation of Aboriginal rights. However, there was also strong agreement that permanent no‐take zones would help reduce over‐fishing. The National Marine Conservation Area program is in its infancy and it remains to be seen how the “strictly protected” zone of the legislation will be interpreted in relationship to Aboriginal harvesting practices. However it is clear that successful conservation will only occur with Aboriginal consent in many areas and there needs to be greater investment in understanding Aboriginal perspectives on marine conservation.  相似文献

Proslavery propagandists developed a standard line on the domestic slave trade: the trade was of only marginal importance to the system of slavery, and the trader was an outcast. In recent decades, historians have recognised a strong propaganda element in this position but—even in recent specialist studies of the trade—the assumption has been that notions of paternalism must have caused owners to feel a measure of unease in dealing with the trader. The present study brings new evidence to dispute this assumption and suggests that traders found no difficulty in being accepted as respected citizens of the Old South. The essay points to two key elements in the proslavery position on the trade—first, the notion of the trader as outcast, and second the concept that black people were not capable of deep and lasting emotional suffering. The ‘trader as outcast’ operated at the level of propaganda and was not really believed: the concept of superficial black emotions operated at a deeper level and was internalised by owners. Notions about shallow black emotions allowed slaveholders to break up families and to deal comfortably with the trader while still maintaining a self‐image as benevolent paternalists.  相似文献

A small‐scale industry ‘renaissance’ has characterized recent academic literature on industrialization and development policies. This comes as a reaction to the manifest difficulties facing mass production economies and to the sometimes spectacular performance of small‐ and medium‐sized enterprises (SMEs), particularly in Europe. The causes of the above success, together with the accompanying theorizations — such as the flexible specialization approach — are manifold and contradictory. Furthermore, theories on the present and future of SMEs vary as regards both optimism and policy implications — supra‐national, national or regional. Recent EU policies towards SMEs present an amalgam of instruments which, albeit often economically effective, constitute chiefly a political gesture.  相似文献

A fractious UN Security Council has contributed to the decline in effectiveness of a number of UN sanctions adopted in recent years. Yet they remain a tool of the Council, for example with regard to Libya in 2011. The challenge is to understand how UN, country (US) and regional sanctions (EU, AU, Arab League) can be meaningful in such a climate. The four books reviewed make various suggestions, from clarity of mandate to better evaluating impact. Mikael Eriksson's Targeting peace seeks to evaluate the complexity of the sanctions policy process. He argues that effectiveness comes partly from understanding politics (episodes of sanctions), but also from institutional reform—‘black box’ processes, as he calls them. Sanctions are more successful as part of a wider package. Clara Portela in European Union sanctions and foreign policy examines the use of sanctions as a political tool, including the suspension of development aid and the withdrawal of trade privileges. She shows how the EU plays an important role in signalling and constraining when UN sanctions are weak. For example, informal measures like the 2003 EU decision to invite only dissidents to national day receptions in Havanna resulted in the release of detainees that it had aimed for. The high rate of success of development aid cut‐off stands in sharp contrast with EU Common Foreign and Security Policy sanctions. The unintended consequence of good intentions is also highlighted by both Portela and Eriksson—Zimbabwe in particular but also Côte d'Ivoire and Iran pose similar challenges. The imposition of EU or UN sanctions is easier than reaching consensus to lift them, although events in Burma (Myanmar) in 2012 have resulted in smooth suspensions of most US and EU sanctions. All four books show that targeted sanctions cannot be seen as stand‐alone measures, nor assessed in isolation. Sanctions are multi‐faceted and require detailed assessment of political context, episode and institutional process.  相似文献

In 1994, the Rwandan civil war and genocide produced thousands of orphans. Alongside the war, the growing HIV/AIDS crisis in Rwanda has produced a current population of about 300,000 orphans — many of whom are compelled to head households. These orphans urgently require land use rights, but many find that their rights to their deceased parents’ customary land holdings are denied or restricted by their guardians and others. Despite the legal protections for children that are guaranteed within Rwanda's laws, the reality is that many guardians do not respect orphans’ land rights and few orphans have sufficient access to administrative and legal forums to assert and defend these rights. In contrast to most accounts in the literature that discuss more generally the issue of African orphans’ land rights in the context of adults’ land rights, this article focuses on specific cases in which Rwandan orphans independently pursued their land rights. Ultimately, the article concludes that in Rwanda — and elsewhere in Africa — government officials should re‐examine their ideas about guardianship and grant orphans urgent attention as individuals and as a special interest group.  相似文献

Throughout the first three decades of the twentieth century, black people in New York City encountered white violence, especially police brutality in Manhattan. The black community used various strategies to curtail white mob violence and police brutality, one of which was self-defense. This article examines blacks’ response to violence, specifically the debate concerning police brutality and self-defense in Harlem during the 1920s. While historians have examined race riots, blacks’ everyday encounters with police violence in the North have received inadequate treatment. By approaching everyday violence and black responses—self-defense, legal redress, and journalists’ remonstrations—as a process of political development, this article argues that the systematic violence perpetrated by the police both mobilized and politicized blacks individually and collectively to defend their community, but also contributed to a community consciousness that established police brutality as a legitimate issue for black protest.  相似文献

Efforts to reduce extreme poverty by assisting poor people to cross income or asset thresholds are receiving increasing attention in social protection programming. Livelihood‐promoting interventions aim to reduce vulnerability, so that participants can manage moderate risk and ‘graduate’ from social protection provision. This article elaborates the theory of change underpinning the notion of graduation and explores the range of enabling and constraining factors that facilitate or undermine this change process, drawing on case studies from Bangladesh, Ethiopia and Rwanda. The authors distinguish ‘threshold’ graduation from ‘sustainable’ graduation and argue that multiple factors operating beyond the household level — such as market conditions, community investment and scale effects — have significant implications for the graduation potential of social protection programmes.  相似文献

This article surveys and discusses prominent protagonists of the debate on socio-economic inequality in the Arab region, with a special focus on the World Bank and Egypt. According to official data, the region holds remarkably low Gini coefficients in a context of declining inequality. This contradicts the popular perception of high social inequality as a major cause of regional protests since the Arab Spring; hence the reference to a ‘puzzle’ in mainstream literature. The debate about the reality of social inequality in the region has developed since 2011 — particularly in regard to Egypt, where income and consumption data are periodically collected by means of household surveys. Inequality measures based on this method alone, while income taxation data are inaccessible, are highly questionable and conflict with various observations and calculations based on other indicators such as national accounts, executive income or house prices. Yet, the World Bank upholds official inequality findings in portraying the Arab upheaval as the revolt of a ‘middle class’ that aspires to greater business freedom, in consonance with the neoliberal worldview.  相似文献

Discourse on the information society currently highlights issues of networks, flows and mobilities as prime organizers and re‐organisers of time—space relationships. Such discourse promotes notions of the flexible use of time and space, of people's decoupling from place and even of the end of geography — the belief that distance does not matter. Yet, in this article we argue that the roles of geographical stationarity and proximity in everyday life — understood as the creation and maintaining of pockets of local order — indicate the continuing and often neglected importance of the friction of distance. We demonstrate this empirically by focusing on the home as a pocket of local order, investigating the intensity and spatial extension of people's everyday activities, projects and contacts — their corporeal, virtual and medial (media‐related) mobilities — with the world outside. We support our thesis with data from the population, household and individual levels.  相似文献

Over the past few years, the role of private sector organizations as actors and investors in development processes has received increased attention. This article explores the rise of ‘philanthronationalism’ in Sri Lanka: the co‐development of business and philanthropy methods as a response to patronage, nationalization and militarization in the post‐war environment. Drawing on ethnographic research into indigenous forms of corporate social responsibility (CSR), the article identifies four kinds of philanthronationalist practice — passive, assimilative, reactive and collaborative — that provide a logic, mechanism and ethic for private sector development initiatives in the island whilst promoting a vision of the ‘Sinhala Buddhist’ nation state. Noting the emergence of similar philanthronationalist practices in Myanmar, the article concludes by arguing that the Sri Lankan case is unlikely to be unique and calls for further research into the partnerships that emerge between private philanthropy and nationalist movements in conflict/post‐conflict processes around the world.  相似文献

Despite the enormous energy devoted to generating the right policy models in development, strangely little attention is given to the relationship between these models and the practices and events that they are expected to generate or legitimize. Focusing on the unfolding activities of a development project over more than ten years as it falls under different policy regimes, this article challenges the assumption that development practice is driven by policy, suggesting that the things that make for ‘good policy’— policy which legitimizes and mobilizes political support — in reality make it rather unimplementable within its chosen institutions and regions. But although development practice is driven by a multi‐layered complex of relationships and the culture of organizations rather than policy, development actors work hardest of all to maintain coherent representations of their actions as instances of authorized policy, because it is always in their interest to do so. The article places these observations within the wider context of the anthropology of development and reflects on the place, method and contribution of development ethnography.  相似文献
