Edge Angle as a Variably Influential Factor in Flake Cutting Efficiency: An Experimental Investigation of Its Relationship with Tool Size and Loading

Simple flake cutting tools were utilized across broad chronological and geographical ranges during prehistory. Fundamental to their functional utility is the presence of a relatively acute working edge. The acuteness of this ‘edge angle’ is widely hypothesized to be a primary determinant of cutting efficiency and, subsequently, of potential consequence to prehistoric peoples. However, the influence of the cutting edge angle in flake tools on the ability (efficiency) of tool users to cut through objects has not been empirically investigated under explicitly stated experimental conditions. Moreover, no consideration has been given to whether this relationship is dependent upon the size of the tool. Here, the influence that edge angle exerts on human stone tool users is examined experimentally in terms of efficiency during a cutting task, while also considering the relationship between edge angle, loading (i.e., the force applied) and overall flake size. The results demonstrate that there is a highly significant relationship between more acute working edges and increased cutting efficiency in the smallest flake tools tested. Above a certain flake‐size threshold, however, the working edge angle has no influence on cutting efficiency because larger flakes appear to facilitate the application of greater working loads by tool users. These results have important implications for potential flake selection criteria by prehistoric peoples, especially in relation to utility, function and the changing effects of edge angle through a sequence of retouch.     

Body Snatching & Grave Robbing: Bodies for Science

This paper parallels the history of body snatching for dissection in the United States with the robbing of Native American graves by nineteenth‐century anthropologists for osteological collections. The implications of the similarities revealed are discussed; specifically whether ethical responsibilities to the deceased were being upheld by researchers and how these practices were maintained through the exploitation of marginalized members of society. In both cases, bodies were commodified in the grave (interred as people and later extracted as resources) and clandestinely acquired, studied and then disposed of or stored away. For doctors, the traffic in cadavers ended when voluntary donation of bodies to science increased in the twentieth century. For anthropologists the situation has been reversed, as they now face the potential destruction of their skeletal collections as a result of legal reforms such as NAGRPA.     

Tradition as a governing theme in the writings of John Cassian

John Cassian has been criticized in recent scholarship for historical inaccuracy – but it is not self‐evident that his works were intended as histories in the sense that is supposed by that criticism. Instead, Cassian presents himself as the promoter of key traditions. This paper describes of Cassian's own thinking about ‘tradition’ as a key theme in his works. To that end, it aims to redress scholarly misgivings about the worth of Cassian's writings by taking them as the transmission of identifiable traditions into early to mid‐fifth‐century Gaul (rather than as documentary evidence for late fourth‐century Egyptian monasticism).     

‘Enormous Opportunities’ and ‘Hot Frontiers’: Sub-Saharan Africa in U.S. Grand Strategy, 2001-Present

Abstract

This article argues that, in the 21st century, there has been a significant turnaround in the US approach to Sub-Saharan Africa. No longer is the region viewed solely as the site of human tragedy and internal wars where Washington has no tangible interests. Instead, US policymakers have increasingly viewed this part of Africa as a site of valuable commercial, geopolitical, and security interests—with particular emphasis on petroleum reserves, the market potential of its growing population, and its apparent locus as a site of transnational Islamist terrorism. Sub-Saharan Africa is now considered in grand strategic terms. Unintended consequences of US intervention are already visible, however; as it integrates the region into its global strategic calculus, the United States has begun to repeat mistakes made in other key regions of the world.     

‘We wouldn't be dead for quids’: Hansonism,Fascism, Death and Difference

There are a number of ways in which the Australian political movement led by Pauline Hanson can be implicated in the totalitarian episodes of the twentieth century. But there are also significant differences between what Hansonism presents us with in Australia and what totalitarianism has presented us with in Europe, in the fascist and Stalinist regimes with which totalitarianism is associated. The suggestion in this paper is that totalitarianism can be understood in schematic terms as a mutation of the symbolic order through which differences have been arranged and evaluated in Western thought since the time of the ancient Greek philosophers. Specifically, it belongs with the history of the binary opposition. Its mutation is that it attempts to realize — that is, to accomplish in reality — the fiction of the binary structure, which is its claim to comprehend or to be able to totalize and exhaust the space over which its positive and negative terms must govern. In a contemplation of death and difference, the question is considered here of what is to be gained for thought in characterizing Hansonism as a neo‐fascist phenomenon.     

Dental Health of Free Blacks in New York State during the Mid‐19th Century

The current research will examine the frequency of carious teeth, periapical abscesses and ante‐mortem tooth loss in the Newburgh Colored Burial Ground (1830–1870), a free black cemetery in Newburgh, New York. The Newburgh material is compared with skeletal samples from the New York African Burial Ground, New York State almshouses, a free black cemetery from Philadelphia and middle‐class/upper‐class European cemeteries. Although previous research suggests that dental health became worse throughout the 19th century, there is no consistent pattern between the 17th‐century and 18th‐century skeletal sample of enslaved blacks from New York City and 19th‐century free blacks from Newburgh and Philadelphia. The frequency of dental caries does increase through time but the other indicators change little (equal or fewer ante‐mortem tooth loss) or suggest an improvement in dental health (fewer periapical abscesses) through time. Relative to contemporaneous populations, the individuals from Newburgh appear much more similar in terms of dental health to upper‐class and middle‐class European groups than to the other marginalised groups considered in this research. The impact of the economic, political and social changes that accompanied the Industrial Revolution and their potential impact on dental health are considered.

THE TIME OF THE SELF AND THE TIME OF THE OTHER

What is time? This essay offers an attempt to think again about this oldest of philosophical questions by engaging David Hoy's recent book, The Time of Our Lives: A Critical History of Temporality, which proposes a “history of time‐consciousness” in twentieth‐century European philosophy. Hoy's book traces the turn‐of‐the‐century debate between Husserl and Bergson about the different senses of time across the various configurations of hermeneutics, deconstruction, poststructuralism, and feminist theory. For him, what is at stake in such a project is to distinguish between the scientific‐objective “time of the universe” and the phenomenology of human temporality, “the time of our lives.” Hoy's approach is to organize his book around the three tenses of time—past/present/future—and to view objective‐scientific time as derived from the more primordial forms of temporalizing lived experience that occur in our interpretation of time. In my reading of Hoy's work, I attempt to explore how “time” (lived, experiential, phenomenological) can be read not in terms of “consciousness” (Hoy's thematic), but in terms of the self's relationship with an Other. That is, my aim is less to establish a continental tradition about time‐consciousness, understood through the methods of genealogy, phenomenology, or critical theory, than it is to situate the problem of time in terms of an ethics of the Other. In simple terms, I read Hoy's project as too bound up with an egological interpretation of consciousness. By reflecting on time through the relationship to the Other rather than as a mode of the self's own “time‐consciousness,” I attempt to think through the ethical consequences for understanding temporality and its connection to justice.     

Global health ethics: the rationale for mutual caring

Despite spectacular twentieth century scientific and technological progress, the world is more inequitable than it was fifty years ago. This is evident both in terms of access to health care for individuals, and in relation to the health of whole populations. Disparities in wealth and health within and between nations are widening inexorably and the rapidly expanding global economy has failed to reduce poverty among those with little if any access to health care. In this context the Universal Declaration of Human Rights remains an unrealized aspiration for the majority of the world's people. Given these realities, no single discipline, or body of knowledge is likely to make much difference. For example, approaches based only on neo–liberal economics, as exemplified by the structural adjustment programmes of the World Bank, have not been successful in promoting health equity. The authors believe that an interdisciplinary approach is required, and that bioethics, an interdisciplinary field, can make a contribution towards improving health globally. To do this, the scope of bioethics should be expanded towards a results–oriented global health ethics, based upon widely shared and foundational values that could be carried forward through five transformational approaches.     

NEW HISTORIES OF EMOTION

At the beginning of the twenty‐first century, there was a growing sense that historians had neglected the emotions and failed to think seriously about them. Since then, there has been explosive interest in the history of emotions. What precipitated this development? What has this focus on emotion added to our historical understanding, and what does a historical perspective contribute to research on emotion? Two recent books help us think about these questions. In The History of Emotions, Jan Plamper offers the first book‐length introduction to this field available in English; in Emotional Lexicons, Ute Frevert and a group of fellow historians trace continuities and change in the vocabulary of feeling from the beginning of the eighteenth century to the end of the millennium. At stake, in both books, is the idea that emotions are historically contingent—that history has the ability to shape and transform even the most basic features of human experience. This review essay engages with the central arguments of these books, and offers a somewhat different interpretation of the history of emotions. What is called for, the essay suggests, is not first and foremost a separate history of emotions nor the adding of emotion to existing histories, but new histories that systematically incorporate emotions into their analyses. Historians should seek to demonstrate how emotions are an integral part of history and historiography in a more general sense. Systematic attention to emotions not only adds nuance to a historical narrative, the essay concludes, but also fundamentally affects our ideas about how history actually happens.     

South Africa,the world and AIDS (Respond to this article at http://www.therai.org.uk/at/debate)

South Africa has been at the centre of world history for over a century and it is now the focus of all eyes for the World Cup. The country has been a by‐word for racial inequality and more recently for crime and violence. But it is also notable for social progress and cultural vitality. The HIV/AIDS epidemic has claimed more victims there than anywhere else, a tragic sequel to apartheid. Successive political leaders highlight the contradictions of this historical moment in poignant, even Shakespearean ways. The author briefly reviews three books by anthropologists on AIDS there and suggests that South Africa is likely to remain a source of innovation for the discipline. But we need to take a broader view of world history than at present.     

Changing Notions of Authenticity: Presenting a Castle Over Four Centuries

Bolsover Castle is a 17th‐century mock‐medieval castle built for the Cavendish family. First impressions suggest that its Pillar Parlour has survived with little alteration for nearly four centuries. In reality, there have been minor but telling changes to its fabric. The 18‐century Cavendishes venerated the castle as a shrine to their ancestors. Bolsover’s 19th‐century tenants recreated a romantic Olden Time appearance. The public bodies responsible for the castle in the 20th century used archaeology to reconstruct its 17th‐century form. In each case, these custodians aimed to present the site ‘authentically’, but their work reveals their own contemporary readings of the castle’s history. This evidence, gathered for a Conservation Plan, allowed English Heritage’s re‐display of the castle (1996–2001) to take a more reflective and positive approach to creating new meanings. This use of history to create local important meanings should give good cheer to those managing similar small but significant sites across the world.     

Beyond the Mirrored Horizon: Modern Ontology and Amodern Possibilities in the Anthropocene

Early talk of the Anthropocene has been prompted by material evidence of the incoherence of ontological divisions between humanity and the rest of Earth. Yet, ironically, it has also been dominated by modern narratives about human distinction, autonomy, and dominion. Along with recrimination about the death of nature, the modern Anthropocene carries hope of human redemption through natural evolution or technological progress. The resulting narratives of enlightened planetary stewardship reduce earthly multitudes to a common denominator, shoring up the mirrored horizons within which modern humans encounter only themselves. In response, I explore amodern possibilities for action in an Anthropocene beyond modern referents of nature and culture. These possibilities open up choices within planetary dynamics that are inherently human but not reducible to human agency. This is a politics of sustenance attuned to difference and relation and directed to the multitude of human‐other‐than‐human collectives, to the specific shared projects of existence, in which human interests are composed.     

RETHINKING RACE HISTORY: THE ROLE OF THE ALBINO IN THE FRENCH ENLIGHTENMENT LIFE SCIENCES1

The scholarly quest to recover the construction of racial difference in the Enlightenment‐era life sciences generally overlooks a singular fact: the vast majority of eighteenth‐century thinkers who were engaged in theorizing the human were often far more preoccupied with preserving a belief in an essential human sameness than they were in creating categories of essential difference. This article charts the problem of a potential human sameness as it related to questions of category, biological processes, and the human and non‐human through an examination of a neglected and key construct in the eighteenth‐century life sciences, the albino. The albino was absorbed into a scientific narrative in 1744 when Maupertuis used the concept to put forward a theory of shared origins or monogenesis. Positing that the nègre blanc—quite literally a “white Negro”—was a racial throwback, a reversion to a primitive whiteness, Maupertuis inspired a new generation of thinkers, most notably the great French naturalist Buffon, to assert categorically that blacks had degenerated from a prototype white variety. The significance of the concept nègre blanc, which has not been studied sufficiently, cannot be overestimated. In addition to the fact that the new role of the nègre blanc clearly said as much about whiteness as it did about blackness, the albino generated a new diagnostic chronology of the human species.     

From the Little Tree,Half a Block Toward the Lake: Popular Geography and Symbolic Discontent in Post‐Sandinista Managua

Abstract: The inhabitants of Managua, Nicaragua have a sophisticated, often bitingly ironic, popular geography that they use to navigate the city. The Nicaraguan capital has been destroyed twice by earthquakes, ravaged by war, left to decay for lack of funds, transformed by the creative destruction of speculative capitalism and subjected to a series of ideological impositions. Few people know the official names of streets, and recent governments have not had the ability to put up signs. So a supple system of popular geography dominates, resisting and ridiculing attempts to impose an official order, and adapting to change while preserving a bottom‐up sense of memory, history and place. Drawing on Allan Pred's classic account of popular geography in late nineteenth century Stockholm, I use Managua's language of spatial orientation as a window into peripheral modernity and the politics of everyday life.     

Individual Accessibility Revisited: Implications for Geographical Analysis in the Twenty‐first Century

Analytical methods for evaluating accessibility have been based on a spatial logic through which the impedance of distance shapes mobility and urban form through processes of locational and travel decision making. These methods are not suitable for understanding individual experiences because of recent changes in the processes underlying contemporary urbanism and the increasing importance of information and communications technologies (ICTs) in people's daily lives. In this paper we argue that analysis of individual accessibility can no longer ignore the complexities and opportunities brought forth by these changes. Further, we argue that the effect of distance on the spatial structure of contemporary cities and human spatial behavior has become much more complicated than what has been conceived in conventional urban models and concepts of accessibility. We suggest that the methods and measures formulated around the mid‐twentieth century are becoming increasingly inadequate for grappling with the complex relationships among urban form, mobility, and individual accessibility. We consider some new possibilities for modeling individual accessibility and their implications for geographical analysis in the twenty‐first century.     

Horror,hubris and humanity: the international engagement with Africa, 1914–2014

This article examines the international engagement with Africa from the First World War and the apex of colonial rule through to the present day. It is argued that there have been dramatic shifts throughout this period—from increasing interventionism on the part of the colonial state, to decolonization and the emergence of nation‐states with independent foreign policy programmes, to the predations and influences of the Cold War, to the developmentalism and humanitarianism of the contemporary era. Yet, there has also been marked continuity in terms of policy, perception and practice. In particular, Africa has long been seen in terms of economic opportunity—a place where markets and raw materials abound—and of military and political threat, a place in which intrinsic instability makes external intervention both desirable and inevitable. While immediate contexts have changed over time, the international engagement with the continent remains essentially economic and military. A concern for democratization and development represents a relatively new element, although even this can be traced to the paternalistic humanitarianism of the colonial era and, earlier still, moral stances toward Africa in the nineteenth century.     

Living with nuclear hedging: the implications of Iran's nuclear strategy

For the past decade, much attention has been devoted to the potential consequences of a nuclear‐armed Iran. Yet the binary ‘acquisition/restraint’ lens through which the Iranian nuclear issue is frequently viewed is limiting. There is now much evidence to suggest that Iran is engaged in a strategy based on nuclear hedging, rather than an outright pursuit of the bomb. This does not change the need to contain Tehran's proliferation potential, yet it does add another layer of complexity to the challenge. Iran will retain a low level of latency whatever the final outcome of longstanding diplomatic efforts to constrain the scope and pace of its nuclear efforts. This article will explore the implications of Iranian nuclear hedging and consider how regional rivals might interpret and respond to Tehran's nuclear strategy. On a larger scale, the article will explore the potential impact of the international community's approach to the Iranian case—implicitly recognizing, even giving legitimacy to, hedging—both in terms of the future of the Nuclear Non‐Proliferation Treaty (NPT) and the ability of the international community to limit the negative effects of this form of proliferation behaviour.     

Placing Sanctuaries in Their Socio‐Political Landscapes: A Diachronic Approach to the Late Iron Age Communities in South‐East Iberia (Fourth–Second Centuries BC)

This paper explores the relationship between the historical dynamics and the transformations observed in pre‐Roman cult places in eastern Iberia between the fourth and second centuries BC. These are analysed through a case study: the sanctuary of La Luz (Murcia), located in the Segura Valley, in south‐east Iberia. Three main religious changes are discussed from this perspective: the development of the sanctuary in the fourth century BC, the changes observed in its archaeological record in the third century BC, and finally its destruction in the second century BC. These offer a diachronic view of the transformations, and illustrate the different levels at which they were expressed, from the archaeological record to the landscape. The work aims to provide a different perspective from previous studies in this area and a new view of the cult places in south‐east Iberia within their socio‐political landscape and the Mediterranean historical context.     

THE ECOSYSTEM HEALTH METAPHOR IN SCIENCE AND POLICY

Ecosystem health' is an increasingly common metaphor in the langauge of science and policy. Given the prominence of both the ecosystem and health concepts within geography, this paper examines the meanings generated by the adoption of the metaphor for scientific research and for environmental policy on the North American Great Lakes. 'Ecosystem' can be characterized as an entity, an abstract concept, or a perspective. As perspective, ecosystem shares many features of postmodern science, emphasizing complexity and holism and calling for the inclusion of human beings in our considerations of nature. The ecosystem health metaphor is politically powerful in its ability to evoke action and concern for the environment with an appeal to the universal experiences of human ill-health. The organismic ecosystem health metaphor provides a new, relevant way of thinking about the natural world. In policy discourse, however, metaphor can be problematic in that there is potential for the author or speaker to hide behind the nonliteral language. Moreover, the acceptance of the ecosystem health metaphor which can draw upon widely held beliefs and norms implies that other ways of knowing the world are necessarily omitted. We highlight some of these issues in a case study of a policy document prepared by the Ecological Committee of the Great Lakes International Joint Commission. To continue to know how to study nature in new ways, metaphors must be encouraged, but their meanings must also be widely explored     

Global Change and Southern Africa

The developing nations of southern Africa have previously been identified as vulnerable to the vagaries of global change, particularly in terms of future climate change. This paper explores recent climate change scenarios for the region in terms of some representative sectors of the environment‐society interface, namely biodiversity, agriculture and related land uses, water resources and health issues. It is concluded that the impacts of predicted climate changes over the next century are likely to be very marked indeed. Biome distribution, agriculture, rangelands and water resources are highlighted as being negatively impacted in ways that will increase the vulnerability of the great majority of the region's population to natural hazards. The potential impact of these changes on the prolific biodiversity of southern Africa is clear. Holistic policy responses, incorporating both environmental and human development concerns, are required in the near future if a crisis is to be averted.
