Mechanisms of Failure and Slope Development in Rock Masses

This paper examines the mechanisms of failure in jointed rock slopes. The distribution of discontinuities is a significant control of rock-mass stability, determining the mechanism by which blocks fail from a cliff, and the consequent slope development through time. It is often assumed that the principles of single-block movements are geomechanically similar to those of larger, multiple-block rock-mass failures, under a given set of boundary conditions and controlling variables. Results presented here, based on computer modelling using the Universal Distinct Element Code (UDEC), show that such assumptions are not always correct. After a theoretical modelling exercise, real-world rock slopes were studied from the Portland Limestone outcrop of the Isle of Purbeck, England. There is good association between the theoretical results and model output for the fieldsites. The conclusions are thus useful in enhancing knowledge of jointed rock-mass failure conditions, and improving understanding of rock-slope development.     

Process,Perception and Power: Notes from ‘Participatory’ Research in a Zimbabwean Resettlement Area

The increased popularity of ‘participatory’ methods in research, development projects, and rural extension in developing countries, has not consistently been accompanied by a critical evaluation of the quality and reliability of knowledge created and extracted in the process. In this article, the author employs her own research using Participatory Rural Appraisal (PRA) in a Zimbabwean Resettlement Area, to examine how knowledge is created through this type of research act, and how later research may be used to turn back and ‘make sense’ of PRA data. The article explores how power relations among participants are both revealed and concealed in PRA, focusing specifically on the implications for gendered perspectives. The paper also highlights the dynamic, contested and often contradictory nature of ‘local knowledge’ itself. Apparently transparent chunks of ‘local reality’ gleaned through PRA can turn out to be part of complex webs of multiple ideologies and practices. The author argues that while participatory methodologies may offer effective ways of beginning a research project, adoption of short PRA workshops in academic or project related research could lead to dangerously faulty representations of complex social worlds.     

New life in Japan's ‘endingness’ business

The Japanese deathcare and Buddhist goods industry is a growing field, emerging out of radical shifts in the socio-economic conditions of everyday life: smaller households, an ageing population and more irregular employment/lifestyle patterns. Based on fieldwork, this article reports tectonic ruptures within Japan’s household-based mortuary system and Buddhist practice. It takes readers to ENDEX, the premier convention for Japan’s ‘ending industry’, where new ‘life’ emerges from the falling away of older death rites that get remixed and remade into newer experimental practices, businesses and business subjectivities. Examples range from high-tech gravestones and drones to competitions for the ‘Hottest Priest’ and best encoffiner. This article engages with these new necro-technologies and asks why the old deathcare system is falling apart. What are the socio-material effects of its unravelling? And what does the futurity of necro-praxis look like in Japan (and elsewhere) when the existential fabric of mortality may be torn apart?     

Proselytizing Nationalism: Protestant Missionaries and the Arab Awakening Debate

This article examines the historiographical debate concerning the origins of Arab nationalism as postulated by George Antonius in his book, The Arab Awakening: The Story of the Arab National Movement and the theory of historical construction. After establishing the theoretical framework of the study with an overview of Hayden White's views on how history is written, it progresses into a study of the historiography of Arab nationalism. Here, the scholars Sylvia G. Haim, C. Ernest Dawn, Rashid Khalidi, and Fruma Zachs and their writings are chronologically dissected, with each academic analyzed via White's theories of historical construction. Through studying their respective positions, it is shown that these texts are culturally relative according to the era in which they were written. It is argued that no work of scholarship can be fully removed from outside influences. Specifically, politicization of academics and the consequences of such endeavors are shown as inextricable from the created narrative. Because of the need for culturally relative knowledge so that it can be applicable to audiences outside of academia, scholars who write for an express purpose (such as answering a question for the benefit of others) should not be considered inherently biased. This article poses that academics have a moral obligation to disseminate knowledge to their respective societies due to their assumed removed status as academics. By doing so, human error is acknowledged and room is made for improvement within the field of history. Knowledge does not need to be created for its own sake, but rather so that it might be utilized by society at large. It is suggested that to foster a deeper understanding of a scholar's relationship with society, there should be an increase in academics' civic engagement. This additionally requires serious reflection and enquiry into the standards that would consequently need to be implemented to maintain the integrity of the produced scholarship.     

From Kings to Kids: Refashioning Akan Adinkra Symbols as ‘African’ Motifs in a Nineteenth-Century British Cloth Design

In the nineteenth century, British textile companies began making factory-printed cloth with adinkra motifs for African consumers. These symbolic designs were previously reserved for hand-stamped cloths among Akans of present-day Ghana. Such textiles illustrate the complexities of re-presenting history and shaping cultural knowledge through cloth and colonial exchanges. This article focuses on the design and circulation of one specific British textile design with adinkra symbols made during the 1890s to 1930s, the earliest recorded evidence I have found of adinkra in factory-printed cloths. This textile pattern reveals how merchants, designers and printers historically transformed adinkra symbols from Akan society to become global markers of Africa.     

‘It’s a very isolating world’: the journey to HIV care for women living with HIV in British Columbia,Canada

HIV health services research conventionally defines place in terms of proximity to care. However, understandings of place must also include the social spaces that women living with HIV (WLWH) occupy which shape their experience of health and access to care. Drawing on focus group data from the Canadian HIV Women’s Sexual and Reproductive Health Cohort Study, we explored how 28 WLWH navigate geographic place and social space in attempting to access HIV-related healthcare within and across a range of urban to rural localities in British Columbia (BC), Canada. We describe how existing services, even if physically close, can be socially marginalizing as women confront HIV stigma, racism, and classism, which operate to exclude women from the places and spaces they must access for care. We also emphasize how women enact ‘geographies of resistance’ and succeed in carving out their own safe options for care and support. Finally, we share recommendations identified by women themselves towards developing local and community-driven ‘geographies of change’ that support the health and healing of diverse communities of WLWH. Our findings stress the urgent need to acknowledge and redress socio-spatial barriers to care and to work with WLWH to co-create a therapeutic landscape that reflects women’s diverse identities, localities, emotions, and experiences.     

New World Paleoethnobotany in the New Millennium (2000–2013)

This article evaluates the current state of paleoethnobotany since Hastorf’s 1999 review published in this journal. We discuss advances in methods, ancient subsistence reconstructions, the origins and intensification of agriculture, and how plants inform on issues of political economy and identity. Significant methodological developments in the extraction, identification, and analysis of starch grains and phytoliths have led to advancements in our knowledge of early plant domestication and the transition to food production. Paleoethnobotanists increasingly are using more complex quantitative techniques to characterize their data, which have resulted in more nuanced interpretations of plants that fall within the purview of social archaeology and allow us to address issues related to gender, identity, and ritual practice.     

Taking back taste: feminism,food and visceral politics

Despite much thoughtful agro-food scholarship, the politics of food lacks adequate appreciation because scholars have not developed a means to specify the links between the materialities of food and ideologies of food and eating. This article uses feminist theory to enliven a discussion of what the authors call visceral politics, and thus initiates a project of illustrating the mechanisms through which people's beliefs about food connect with their everyday experiences of food. Recent work on governed eating and material geographies is brought together with poststructural feminism in order to move towards a non-dualistic, visceral understanding of (everyday) socio-political life. In showing how the mind–body whole can be conceived as a singular, albeit ambiguously-unified agent, the article prefigures a more complete disclosure of the play of power in food systems. Food is shown as a means to trace power through the body in order to understand the making of the political (eating) subject. Specifically, reconceptualizing taste and the ‘Slow Food’ (SF) movement of taste education helps to concretize what a visceral politics of food might look like. The authors conclude that appreciating how food beliefs and representations exist materially in the body is crucial to the ability of food-based movements to inspire action across difference and achieve their progressive goals.     

WORKING WITH 'WILD ROSE I': LEAN PRODUCTION IN A GREENFIELD MILL

The Alberta Newsprint Company mill in Whitecourt, Alberta, with its state-of-the-art paper machine dubbed Wild Rose I' is one of the most efficient newsprint mills in North America. This paper documents the systematic drive by the Alberta Newsprint Company to achieve lean production by the use of flexible work practices in a greenfield mill, which began production in 1990. The analysis begins by examining the way in which the workforce for the new mill was recruited as the first step to creating a flexible workplace. Information from questionnaires completed by 96 employees, who represent approximately half the total labour force, and semi-structured interviews with managers and employees, is used to describe the extent to which the anc mill has achieved various forms of labour flexibility. The nature and extent of these new work arrangements are compared among departments within the mill. Finally, we explore the recent restructuring of wages in the mill. These events illustrate some of the unanticipated consequences arising from the implementation of lean production in a remote geographical setting.     

ON THE PLAUSIBILITY OF THE SUPPLY-DRIVEN INPUT-OUTPUT MODEL: EMPIRICAL EVIDENCE ON JOINT STABILITY*

ABSTRACT. This paper addresses the issue of the plausibility of the supply-driven input-output model from an empirical standpoint. We suggest that requiring production coefficients to remain perfectly fixed during an application of the supply-driven input-output model is unnecessarily restrictive given the extensive use of approximation methods in mathematics, economics and regional science. Simulations with the supply-driven version of an input-output table for a representative region are shown to result in changes in the corresponding production coefficients well within conventional tolerance levels.
