Bridging the divide between studies on disaster risk reduction education and child-centred disaster risk reduction: a critical review

There has been a recent increase in the body of knowledge related to children and disasters. These studies converge into three main fields of research: the impact of disasters on children and their psychological recovery, the integration of disaster risk reduction (DRR) into the education sectors and children’s participation in DRR. This article provides a literature review of the two latter fields of research where the focus is on reducing disaster losses and building resilience prior to a disaster. Overall, 48 studies are critically reviewed and compared in relation to the strengths and weaknesses of their aims, methods, locations of research, impact, and outcomes. The review identified a number of differences between the two fields and significant opportunities for linking the two approaches, sharing lessons and knowledge. Based on the review, recommendations for further research are outlined.     

Fluid mixing induced by hydrothermal activity in the ordovician carbonates in Tarim Basin,China

Permian hydrothermal activity in the Tarim Basin may have been responsible for the invasion of hot brines into Ordovician carbonate reservoirs. Studies have been undertaken to explain the origin and geochemical characteristics of the diagenetic fluid present during this hydrothermal event although there is no consensus on it. We present a genetic model resulting from the study of δ¹³C, δ¹⁸O, δ³⁴S, and ⁸⁷Sr/⁸⁶Sr isotope values and fluid inclusions (FIs) from fracture‐ and vug‐filling calcite, saddle dolomite, fluorite, barite, quartz, and anhydrite from Ordovician outcrops in northwest (NW) Tarim Basin and subsurface cores in Central Tarim Basin. The presence of hydrothermal fluid was confirmed by minerals with fluid inclusion homogenization temperatures being >10°C higher than the paleo‐formation burial temperatures both in the NW Tarim and in the Central Tarim areas. The mixing of hot (>200°C), high‐salinity (>24 wt% NaCl), ⁸⁷Sr‐rich (up to 0.7104) hydrothermal fluid with cool (60–100°C), low‐salinity (0 to 3.5 wt% NaCl), also ⁸⁷Sr‐rich (up to 0.7010) meteoric water in the Ordovician unit was supported by the salinity of fluid inclusions, and δ¹³C, δ¹⁸O, and ⁸⁷Sr/⁸⁶Sr isotopic values of the diagenetic minerals. Up‐migrated hydrothermal fluids from the deeper Cambrian strata may have contributed to the hot brine with high sulfate concentrations which promoted thermochemical sulfate reduction (TSR) in the Ordovician, resulting in the formation of ¹²C‐rich (δ¹³C as low as ?13.8‰) calcite and ³⁴S‐rich (δ³⁴S values from 21.4‰ to 29.7‰) H₂S, pyrite, and elemental sulfur. Hydrothermal fluid mixing with fresh water in Ordovician strata in Tarim Basin was facilitated by deep‐seated faults and up‐reaching faults due to the pervasive Permian magmatic activity. Collectively, fluid mixing, hydrothermal dolomitization, TSR, and faulting may have locally dissolved the host carbonates and increased the reservoir porosity and permeability, which has significant implications for hydrocarbon exploration.     

Disability Consciousness on the Frontlines of Urban Struggle

Drug wars, austerity and gentrification are interwoven social relations in many North American urban centres and are typically met with organising of varying degrees of militancy. Loïc Wacquant characterises many of these sites as highly stigmatised, associated with violence and pathology. In Toronto's downtown east end (DEE), one such stigmatised urban space, disabled activists are far from unfortunate casualties. They tend to refer to the DEE as an “urban battleground”, where disabled people politicise and challenge the DEE's pathology and stigma by linking into emerging radical disability politics across the global North and by developing localised revolutionary disability consciousness. Drawing on oral stories, zines and blogs of disabled activists and workers in Toronto's DEE, this article uses Rachel Gorman's dialectic of disability/disablement to analyse the emergence of revolutionary disability consciousness and the centrality of disabled people on the frontlines of anti‐gentrification and harm reduction organising in Toronto's DEE.     

Milky Quartz Bipolar Reduction and Lithic Miniaturization: Experimental Results and Archaeological Implications

We present experimental data examining the energetics and identification of axial bipolar reduction in contexts of lithic miniaturization on milky quartz. These experiments answer two specific questions. First, does bipolar reduction provide any benefits over freehand reduction? Second, can axial bipolar reduction be distinguished from freehand reduction? Our data show that bipolar reduction requires significantly less time to reduce a percentage unit of core mass and to produce a millimeter of cutting edge on milky quartz than freehand reduction. Milky quartz bipolar reduction surpasses even the cutting edge production efficiency of obsidian pressure blades. We outline a series of quantitative criteria for identifying bipolar cores and flakes. Our results show that bipolar cores and flakes can be distinguished from those produced using freehand reduction by quantifying platform crushing, distal flake rebound scars, bulb shearing, as well as axial, bipolar, and splintered flake terminations. Our results challenge the widely held perceptions about the wastefulness of bipolar reduction and provide clear guidelines for identifying this reduction strategy in archaeological milky quartz assemblages.     

Gendered responses to the 2009 Black Saturday bushfires in Victoria,Australia

This paper presents findings from a gendered analysis of resident responses to the 2009 Black Saturday bushfires (wildfires) in Victoria, Australia. One hundred and seventy‐three people lost their lives in the bushfires and more than 2000 houses were destroyed. Previous research on Black Saturday has largely focused on issues of resident preparedness and response, with limited consideration of the role of gender in household decisions and actions. This paper examines the gendered dimensions of risk awareness, preparedness and response among households affected by the bushfires. Data were collected through in‐depth interviews with over 600 survivors and a questionnaire of 1314 households in fire‐affected areas. Analysis revealed that women more often wanted to leave than men, who more often wanted to stay and defend property against the bushfires. Nevertheless, findings suggest that broad‐brush characterisations of staying to defend as a masculine response and leaving as a feminine response are misguided. Although some women expressed a strong desire to leave, others were resolute on staying to defend. Equally, while some men were determined to stay and defend, others had never considered it an option. Despite this, the research identified numerous instances where disagreement had arisen as a result of differing intentions. Conflict most often stemmed from men's reluctance to leave, and was most apparent where households had not adequately planned or discussed their intended responses. The paper concludes by considering the degree to which the findings are consistent with other research on gender and bushfire, and the implications for bushfire safety policy and practice.     

旅游减贫与旅游再贫困:旅游发展中不同土地利用方式对贫困人口的影响

旅游发展能否真正减贫以及如何实现减贫应是当前旅游减贫大背景下备受讨论的焦点,并受到了国内外学术界积极关注。然纵观现有研究,对旅游减贫效果的实证探讨及细致剖析尚十分缺乏。本文选取旅游发展中对土地资源的利用作为研究视角,探讨这一过程对贫困人口生存状态的影响。研究以三亚亚龙湾度假区发展对周边两个村庄的土地使用（征用、租用）为例,采用多维贫困概念,探讨旅游发展给两村村民在收入、居住条件、就业及生产方式以及话语权等带来的影响。研究提出了旅游再贫困的概念,意在说明旅游发展在使贫困人口短暂富裕后再次陷入贫困状态的发展现象,是旅游发展之于贫困人口负面影响的一种表征。     

The Civilisation Cards: US Army Style.

Abstract

The term ‘heritage crime’ has been recently brought into the spotlight by English Heritage — the organization tasked with protecting England’s heritage assets — and is attracting an increasing amount of attention from individuals and organizations from a range of disciplines. Heritage crime includes recognized crime types (such as arson, criminal damage, theft, and graffiti) but arguably has a greater impact on the country’s legacy for future generations because of the types of sites affected. This paper presents an initial examination of our understanding of heritage crime, and limitations to that knowledge. The paper contributes an initial typology to facilitate future interdisciplinary discussions of the problems facing heritage assets, and presents a possible route for expanding our ability to tackle this problem. Whilst this is an initial foray into the world of heritage crime, it is hoped that this paper will act as a stimulus for further discussion and action.     

An empirical test of the relative frequency of bipolar reduction in Beds VI,V, and III at Mumba Rockshelter,Tanzania: implications for the East African Middle to Late Stone Age transition

Mumba Rockshelter, Tanzania, is the only East African site spanning a continuous record of more than 100,000 years, including the Middle Stone Age (MSA) to Late Stone Age (LSA) Transition. Rather than examine the presence or absence of traditional markers of “behavioral modernity”, we have endeavored here to respond to the calls of Shea (2011) and Basell (2008) by examining the proportional similarity of a trait present throughout the MSA–LSA sequence at Mumba Rockshelter: the bipolar technique of lithic reduction. We use a quantified, experimentally derived proxy to track the relative amount of bipolar percussion among Mumba's Beds VI, V, and III, namely, waste shatter. Our examination of Mehlman's previously unanalyzed collections from Mumba demonstrates that in terms of bipolar production Bed V is statistically indistinguishable from the Late Stone Age (LSA) Bed III, but significantly different from the Middle Stone Age (MSA) Bed VI. Given that Bed V dates to 56.9 ± 4.8 − 49.1 ± 4.3 ka cal BP, this result is consistent with other evidence that the origins of the LSA in East Africa began well before 40 kya, and that Mumba Bed V represents one of the earliest manifestations of the LSA in East Africa. We conclude with a discussion of factors that may have influenced the increased dependence of bipolar production at the site.     

Ballistically anomalous stone projectile points in Australia

The emergence of stone-tipped projectile weaponry was an important event in hominin evolution. A common archaeological approach to identifying projectile weapons is to extrapolate from optimal values of ballistically-relevant attributes as determined from ethnographic North American weapons and modern experiments. Among the most significant of these attributes is “tip cross-sectional area” (TCSA) because it determines a point's efficiency in penetrating an animal. The warranting argument for projecting these data onto prehistoric artefacts is that past “research and development” necessarily led to stone projectiles with optimal TCSA values for a given delivery system. However, our test of this warranting argument, involving analysis of 132 hafted ethnographic Australian stone projectile points and 102 hafted knives, demonstrates that Aborigines did not optimize TCSA values, thus offering a challenge to TCSA-based narratives about the first appearance of projectile weaponry. This illustrates the difficulty of inferring ancient stoneworkers' design intentions from narrowly-defined optimal values. Instead, tool designs should be considered in the context of the reduction sequences that produced them and the dynamics of transmission of those reduction sequences across generations.     

Measuring core reduction using 3D flake scar density: a test case of changing core reduction at Klasies River Mouth,South Africa

A new core reduction index is presented, calculated as the ratio of flake scar number to 3D surface area (SDI). The index is tested experimentally on five types of core (blade, discoid, Levallois, biface and multiplatform cores) and then applied to the core assemblages from five sub-stages of the Middle Stone Age at Klasies River Mouth, South Africa. Preliminary results indicate that the SDI possesses the desirable attributes of a successful reduction index and is a significant improvement on traditional proxy measures of core reduction. The results of the archaeological case study confirm previous untested observations that cores from the Howiesons Poort and MSAIII sub-stages are more heavily reduced than preceding and following stages, and that local and exotic raw materials as well as different types of cores are all more heavily reduced during these periods. The SDI fills a significant lacuna in available core reduction measures.
