Experimental insights into alternative strategies of lithic heat treatment

Conditions in which thermal fractures occur are explored experimentally, and the results are used to assess heat treatment strategies. We conclude that no single ‘critical temperature’ for thermal fracturing or heat treatment can be specified for any particular raw material, as has so often been attempted, because threshold temperatures exist in relationship to specimen sizes. Our experiments show that smaller specimens are resilient to greater ranges of temperature fluctuations than larger ones, and that by manufacturing/selecting specimens of smaller sizes there is more potential to heat them rapidly and to higher temperatures without producing thermal fractures. We hypothesize a continuum of heat treating strategies between a ‘slow and steady’ strategy, which has overwhelmingly dominated past experimental designs, and a ‘fast’ strategy, which has received much less attention. The paper discusses the economic and technological contexts to which different heat treating strategies might be suited.     

Permeability and Protest in Lane 49: Entangling Materialities of Place with Housing Activism in Shanghai

Since China’s implementation of a neo‐liberal housing regime, housing activism has boomed. Whilst activism is ultimately in place, as increasingly recognised within protest work, there is limited reflection upon how permeable material histories are entangled with the throwntogetherness of place as a site for protest. Employing ethnography over three months, this article follows the emergence, organisation and implementation of housing activism in Lane 49, a public housing community in downtown Shanghai. Utilising feminist geography and feminist political theorisations of material permeability this article contributes to Chinese geographies of protest, providing a local epistemology of housing activism which demonstrates the importance of drawing materiality into understandings of activist tactics. The article also contributes to radical geographies of protest by deconstructing the idea of public protest in a public place and thus offering opportunities to demonstrate how, through blurring public‐private binaries, protest can emerge and survive in authoritative governance regimes.     

Carrying a heavy load: Mayan women’s understandings of reparation in the aftermath of genocide

ABSTRACT

Drawing on extensive testimony from Ixil women survivors of sexual violence, the 10 May 2013 verdict in the genocide trial of former de facto Guatemalan head of state and army general Efraín Ríos Montt highlighted the perpetration of sexual violence as an integral component in the attempt to destroy the Maya Ixil as an ethnic group and thus evidence of genocide. Acknowledging that sexual violence was a weapon of genocide in Guatemala contributes to a critical analysis of how the racialized violence targeted against the country’s indigenous peoples was gendered, and enables the women and men who are survivors of these crimes to seek redress. However, narrating sexual harm within justice-seeking processes is not without complication, and trials alone cannot respond to survivors’ demands for justice and social repair. This article examines how fifty-four Maya Q’eqchi’, Kaqchikel, Mam and Chuj women who are survivors of sexual violence make meaning of the everyday struggles to rethread their lives in the aftermath of genocide. The article uses data from a four-year participatory action research (PAR) project conducted by the authors with this group of Mayan women, including a series of workshops that used creative techniques—drawing, collage, dramatization and body sculptures—to elicit more complex and contestational stories than those emergent from a more linear narrative approach to understanding harm suffered and efforts for redress. Analysis of these data confirms that these Mayan women survivors have woven their understanding of reparation from three main threads: their experiences of loss and harm; their recognition of the Guatemalan state’s duplicity; and their protagonism in justice-seeking processes. The article concludes by arguing that women survivors' desire for repair requires attention to the deep-seated impoverishment that they highlight as the heavy load of gendered violence they carry with them.     

Journeying from “I” to “we”: assembling hybrid caring collectives of geography doctoral scholars

Completing a PhD is difficult. Add a major earthquake sequence and general stress levels become much higher. Caring for some of the nonacademic needs of doctoral scholars in this environment becomes critical to their scholarly success. Yet academic supervisors, who are in the same challenging environment, may already be stretched to capacity. How then do we increase care for doctoral scholars? While it has been shown elsewhere that supportive and interactive department cultures reduce attrition rates, little work has been done on how exactly departments might create these supportive environments: the focus is generally on the individual actions of supervisors, or the individual quality of students admitted. We suggest that a range of actors and contingencies are involved in journeying toward a more caring collective culture. We direct attention to the hybridity of an emerging ‘caring collective’, in which the assembled actors are not only ‘students’ and ‘staff’, but also bodies, technologies, objects, institutions, and other nonhuman actors including tectonic plates and earthquakes. The concept of the hybrid caring collective is useful, we argue, as a way of understanding the distributed responsibility for the care of doctoral scholars, and as a way of stepping beyond the student/supervisor blame game.     

Editorial

Abstract

Solidarity has become a central concept in Christian ethics. Although solidarity or analogous concepts can be found in other Christian traditions, as well as other religious and philosophical systems of ethics, the Catholic social tradition has perhaps most fully developed a concept of solidarity over the last century. This article contends that solidarity as conceived in Catholic social teaching (CST) provides a robust and useful understanding of the social obligations of individuals, communities, institutions, and nations. As a general overview of the concept of solidarity in CST, the article elucidates its biblical, theological and experiential foundations, its historical antecedents, and the goals, methods and scope of solidarity. The article also describes contemporary applications of the Catholic ethic of solidarity, and theoretical and practical challenges to its realization.
