Neighbor-based Properties of Some Orderings of Two-dimensional Space

An ordering of a two-dimensional matrix assigns consecutive integers to the cells in that matrix. This paper evaluates such orderings by concentrating on the differences between each cell's order key and the keys of its spatial neighbors. In all, ten systematically generated orderings and two hundred random trials from a newly defined class of orderings are compared. The row-by-row (raster) ordering often used in remote sensing and in matrix ordering within computer programs minimizes the mean absolute difference, the root-mean-squared difference (and hence the Geary statistic), and the mean maximum absolute difference for both 8-by-8 and 256-by-256 matrices; of the quadrant-recursive (“quadtree-compatible”) orderings examined, the Morton order had the lowest values for both mean absolute difference measures, whereas the Hilbert order had the lowest root-mean-squared neighbor difference. The Morton order has the overall minimum value for the Moran statistic. Heuristic search procedures applied to the 8-by-8 case found orderings which had considerably “better” values for these statistics (higher for Moran; lower for the others) than did any of the above, suggesting that it will be possible to define new systematic orderings with better scores than any ordering currently in the literature.     

Location-Allocation Models of Some Traffic Facilities

The objective of this paper is to formulate location-allocation models of linear facilities, such as bridges, railroad crossings, and staircases. The location-allocation models in this paper differ from existing location-allocation models in that the service provided by the facilities is consumed by trips, with associated origins and destinations. The first part of the paper shows the formulation of these location-allocation problems in one-dimensional space. It is demonstrated that these problems can also be formulated by the use of a rectilinear Voronoi diagram in two-dimensional space. The second part of the paper demonstrates fundamental relationships between the number of facilities and the total length of indirect trips and between the number of facilities and the total number of indirect trips for uniformly and independently distributed origins and destinations.     

Mass violence,trauma, and their children

This article concerns the social construction of collective memory particularly with regard to the social remembering of mass violence and trauma. How do individual memories of mass violence which are often idiosyncratic, nonverbal, and embodied coalesce and crystallize into coherent narratives shared by a group. The books reviewed here demonstrate that there are both discursive means of remembering and non-discursive means of remembering. Social memories can take narrative and textual form or they can take performative and ritual form. How does the non-discursive interact with the discursive and do these interactions depend upon varying social, political, and cultural circumstances? An encompassing theoretical issue is addressed in this literature concerning the adequacy of sociological and anthropological models in the elucidation of trauma memory vs. psychological models which place emphasis on the individual. Subsumed within this question is an inquiry into the adequacies and inadequacies of Western clinical models, such as the PTSD model, in explaining trauma due to mass violence, and the opposition frequently noted among survivors between silence and verbalization. Numerous ethnographic examples are considered in this article but particular attention is paid to the Nazi, Cambodian, and Rwandan genocides.     

Poppies for medicine in Afghanistan: lessons from India and Turkey

This study examines India and Turkey as case studies relevant to the Senlis Council’s ‘poppies for medicine’ proposal. The proposal is that Afghan farmers are licensed to produce opium for medical and scientific purposes. Here it is posited that the Senlis proposal neglects at least three key lessons from the Turkish and Indian experiences. First, not enough weight has been given to diversion from licit markets, as experienced in India. Second, both India and Turkey had significantly more efficient state institutions with authority over the licensed growing areas. Third, the proposal appears to overlook the fact that Turkey’s successful transition was largely due to the use of the poppy straw method of opium production. It is concluded that, while innovative and creative policy proposals such as that of the Senlis proposal are required if Afghanistan is to move beyond its present problems, ‘poppies for medicine’ does not withstand evidence-based scrutiny.

THE POETICS OF ANCIENT GREEK MEMORY AND THE HISTORICAL IMPERATIVE

This book examines Greek engagements with the past as articulations of memory formulated against the contingency of chance associated with temporality. Based on a phenomenological understanding of temporality, it identifies four memorializing strategies: continuity (tradition), regularity (exemplarity), development, and acceptance of chance. This framework serves in pursuing a twofold aim: to reconstruct the literary field of memory in fifth‐century bce Greece; and to interpret Greek historiography as a memorializing mode. The key contention advanced by this approach is that acts of memory entailed an “idea of history” that was articulated not only in historiography, but also in epinician poetry, elegy, tragedy, and oratory. The book offers a rich account of poetic conventions and contexts through which each of these genres counterbalanced contingency through the use of exemplary and traditional modes of memory. This fine analysis highlights the grip of the present on the past as a significant feature of both historiographical and nonhistoriographical genres. The essay argues that this work fills a disciplinary gap by extending the reflection on memory to a new period, Greek antiquity. The retrospective positioning of this period at the outset of Western historical thought brings Grethlein's investigation to the center of debates about memory, temporality, and the meaning history. In engaging with the book's argument, the essay suggests that historiographical memory emerged in Greece not as a first‐order encounter with time, but as a second‐order encounter with forgetting. This confrontation marked a certain separation of historiography from other memorializing genres. Whereas poetic and rhetorical memories were posited against contingency, historiography sought to retrieve those aspects of the past that may otherwise have been irretrievably lost and forgotten. In doing so, it formulated the historiographical imperative as a negation of forgetting that problematized the truth‐value of memory and the very act of remembering the past.     

Gypsy‐Travellers and Welfare Professional Discourse: On Individualization and Social Integration

Abstract: This paper examines the subtle ways in which welfare professionals in the UK construct Gypsy culture as subordinate to the dominant Western concept of “civilization”. Qualitative empirical evidence is presented to show how notions of a resistance to processes of individualization and social integration—which draw on conflicting interpretations of childhood and a perceived lack of aspiration among Gypsy‐Travellers—are seen as legitimate grounds for state and social welfare intervention. The paper argues that a strong group orientation and a more marked gendered division of labour are constructed as being at odds with these dominant social processes. It is posited that the “civilizing” project against Gypsy‐Travellers ignores cultural norms and values resulting in the perception that they are undeserving. The paper suggests that theoretical accounts of social processes at a society wide level require revision in order to understand their varying impact on peripheral minorities in specific spaces.     

滚珠式文物展柜隔震装置性能试验

为有效减小馆藏浮放文物的震害,研制了一款滚珠式文物展柜水平隔震装置。制作了2个文物展柜模型,并在各模型内浮放文物仿品。分别考虑文物展柜底部安装隔震装置、展柜底部浮放地面,进行了振动台对比试验,检测了隔震装置的效果。结果表明:与非隔震条件相比,隔震体系的基频减小,阻尼比增大;地震作用下,隔震体系中的文物仿品产生的位移、加速度峰值明显减小。但是隔震条件下,文物仿品的动力放大系数仍有大于1的情况,且隔震装置的复位能力尚需提高。建议对隔震装置采取的改进措施主要适当减小基频、增大阻尼比、提高加工精度等。     

The Limits of Sasanian History: Between Iranian,Islamic and Late Antique Studies

This essay discusses the position of Sasanian Studies from its inception in the late nineteenth century, to its reinvigoration at the beginning of the twenty-first century. The work also discusses the development of the field of Sasanian history and civilization vis-à-vis the three fields of Iranian, Islamic and Late Antique Studies. It is posited that Sasanians have benefited from cross-disciplinary and new historical frameworks that go beyond the traditional field of Iranian Studies, which was never as interested in the history of the period.     

The strategic logic of Islamic State information operations

Drawing on English and Arabic Islamic State (IS) communiqués produced by its central media units, wilayat information offices and broader supporter base, this study examines the strategic logic of IS information operations (IO). It argues that the overarching purpose of IS's IO campaign is to shape the perceptions and polarise the support of audiences via messages that interweave appeals to pragmatic and perceptual factors. Pragmatic factors—such as security, stability and livelihood—are leveraged in IS messaging by promoting the efficacy of its politico-military campaign and denigrating its enemies’ efforts via rational-choice (logic of consequence) appeals. Perceptual factors—which are tied to the interplay of in-group, Other, crisis and solution constructs—are leveraged via identity-choice (logic of appropriateness) appeals that frame IS as the champion of Sunni Muslims (the in-group identity), its enemies as Others complicit in Sunni perceptions of crisis, and IS as the only hope for solving this malaise. With this approach, IS seeks to resonate its message across a diverse ‘glocal’ constituency and supercharge supporters towards action. IS simultaneously targets its enemies with messaging that manipulates the inherent dualities underlying perceptual and pragmatic factors, vigorously counters criticisms and ‘baits’ opponents into ill-conceived IO responses.     

The Stereoscope and Popular Fiction: Imagination and Narrative in the Victorian Home

The stereoscope was a popular parlour toy that provided a powerful psychological viewing experience in the heart of the domestic space. In this article, I consider the stereoscope’s position as an instrument that was experienced, and often represented, in relation to the imaginative narrative processes of memory and fantasy. By reading the stereoscope’s position within popular fiction, the article seeks to uncover the way in which the stereoscope was consumed. The article shows that for many in the mid-Victorian period, the stereoscope operated as an everyday narrative-forming experience with a strong relation to the popular periodical fiction that was read alongside it in the domestic space. The first section of this article considers the cultural and psychological position of the stereoscope within the home, reading this alongside a number of short stories published in the popular periodic press. The second section consists of an analysis of the stereoscope’s involvement with psychological dualism and self-doubling, issues which stem, in particular, from the device’s reliance on photography. These aspects of the device are explored in relation to a nineteenth-century short story which draws a problematic relation between one’s self and one’s portrait. Finally, the article draws these issues together to show the importance of imaginative narratives within the stereoscopic experience. The viewing conditions of the stereoscope encouraged viewers to engage in an anticipatory, open-ended, and imaginative fantasy narrative. It is this unique narrative character of stereoscopic viewing experiences which most prominently distinguishes the device from other visual media.     

SIMULATING THE WESTERN SEAWAYS

Recent debates on the introduction of Neolithic features to Britain have emphasized the role of the western maritime routes and the possibility of direct or indirect connections from Brittany to Ireland and Argyll. Here we present the results of simulation modelling of maritime voyaging by paddled or sail-powered boat, indicating the likely lengths of the journeys that would have been required. The issue of direct travel vs. short crossings and coasting is explored, and the implications for specific connections, such as those posited to account for cattle remains in a pre-Neolithic context in Ireland, are considered.     

Remembrance of Things Passed: Memory,Body and the Politics of Feasting in New Ireland,Papua New Guinea1

This paper explores the connection between body and memory for the people of the Lelet Plateau of central New Ireland. Through an examination of the processes by which memories of mortuary feasts are created and circulated, I draw attention to the embodied nature of memory as a central facet in the politics of feasting. The approach taken here differs from other prevailing approaches to the body and memory in its exploration of the ways in which memories are created through and within the body, rather than seeing the body, or things representing the body, as signs that are utilised for remembering. In particular, I examine the forms of sorcery which target the participants' bodies, making them experience diarrhoea as a mnemonic process. It is through this that a significant memory of the feast is created, one which stands out notably from numerous other memories, and is the means by which remembrance of the event is transformed into fame for the host.     

Lesbian collaborative web mapping: disrupting heteronormativity in Portugal

Public spaces are constructed around hidden, subtle, non-verbalized and implicit codes of behaviour. These hidden and implicit codes of behaviour are pervasive heteronormative expressions that inscribe socio-spatial landscapes. As a consequence, same-sex public displays of affection are modified, or entirely absent. In the Portuguese sociocultural context public displays of heterosexual and familial affection are common, which prompted us to research how lesbians and bisexual women negotiate same-sex displays of affection in public spaces. The article begins by examining: the co-production of space, gender and sexualities; the pervasive invisibility of lesbian sexualities in public spaces; and the potentialities of participatory geospatial web that connects geographic location to photographs, text and other media shared online. The second half of the article presents the research project ‘Creating Landscapes’. It is argued that a collaboratively created web map by lesbians with positive public space experiences may promote agency and empowerment for lesbian and bisexual women. The article concludes by arguing that creating and sharing collaborative web maps of positive experiences of same-sex public displays of affection can disrupt heteronormativity and create public spaces that are empowering for lesbians and bisexual women.     

MEMORY,MEMORIALS, AND COMMEMORATION1

According to a popular view, the past is present here and now. This is presentism combined with endurantism: the past continuously persists through time to the present. By contrast, I argue that memories, memorials, and histories are of entities discontinuous with present experiences, and that the continuity between past and present in them is a construct. Memories, memorials, and histories are semantic means for dealing with the past. My presupposition that past and present are different is supported by grammar: as verbal tenses show, the past is not present here and now, for otherwise it would not be past. A failure to note this difference is a lack of chronesthesia, a sense of time specific to human beings. I argue that presentism fails to account for the temporal structures of memory and the changes in perspective as we switch from the present to a past situation. My account is perdurantist in the sense that it allows for temporal parts of things such as memorials or tombstones, as well as events such as wars or commemorations. But my main goal is to outline a semantic approach to the past: the tie between past and present actions and events is the semantic ground–consequence relation: a past event is the antecedent grounding a present situation, explaining why it is the case. In addition, I show how we refer to the past by means of two rhetorical figures of speech: synecdoche, using the (emblematic‐) part‐whole relation for relating the past to the present by transposing its sense; and anaphor, which has a deictic function—it points back toward the past. In references to the past, the deictic field is a scene visualized by the speaker and addressees: the deictic field is transposed from a perceptual to an imaginary space.     

Declines in Mammalian Foraging Efficiency during the Late Holocene, San Francisco Bay, California

Resource intensification models that have been posited for prehistoric California predict decreases in foraging efficiency during the late Holocene, Using implications of the fine-grained prey model of optimal foraging theory, I derive an index of the efficiency of vertebrate prey choice from the relative abundances of large- and small-sized prey items. I then test the intensification models with late Holocene mammalian faunas from San Francisco Bay shellmounds. Dramatic linear decreases in the relalive frequency of artiodactyls compared to the smaller sea otters (Enhydra lutris) throughout the occupational histories of particular localities strongly support the resource intensification models. The declines in artiodactyl abundances are not correlated with late Holocene climatic indices developed for this region, with changes in the seasonal use of shellmounds, or with technological innovations. An intra- and interregionally consistent pattern in declining abundances of large mammals in environmentally distinct regions throughout California suggests that resource depression driven by human predators may be the single most important cause of the declines. These patterns have far-reaching implications concerning the long-term human role in structuring prehistoric ecosystems.     

Remembrance as remaking: memories of the nation revisited

This article revisits Anthony Smith's landmark collection Myths and Memories of the Nation (1999) from the perspective of recent developments in cultural memory studies. It argues for a more clearly demarcated distinction between myths and memories which acknowledges cultural memory as a site of new experiential perspectives that often work against the authority of myths, seen as the unquestioned truths about the collective past. Drawing on studies of modern memory cultures, it presents a dynamic and generative model that construes memory in terms of cultural practices of remembrance. It shows that memory is not an unchanging legacy but rather a malleable resource for making shared stories about the past. Where Halbwachs (1925) presumed that social frameworks precede and shape memory, remembrance is presented here as a cultural force that helps to redefine social frameworks and to create links between hitherto unconnected imagined communities.     

Dual roles of semi‐civil society in Chinese democratisation

This paper addresses the question of how a civil society impacts on Chinese democratisation, by examining the nature and features of a Chinese semi‐civil society which could be both a potential for greater democratisation, and a conservative force used by the state to maintain a neo‐authoritarian regime. It challenges the common assumption of the mere positive influence of civil society on democracy in a growing literature on civil society. It also discusses the issue of how the state and the reformer faction within the party saw and will possibly see ‘civil society’ as the rule of arts and a new source of legitimacy in the rules of games for strengthening their power. This is probably more likely than the total collapse and disintegration posited by other writers.     

Tracing resident antagonisms in urban development: agonistic pluralism and participatory planning

This article draws on research with resident action groups and other alliances in Sydney. It investigates the ways in which citizens work beyond the formal planning system to approach and achieve their urban development goals. The post‐political treatment of community voices in planning relies on the centrality of consensus politics in current participatory planning regimes. By providing a democratic outlet that is far removed from the actual development outcome, powerful urban actors can silence through inclusion. Planning theorists have posited that one pathway beyond this post‐political moment in urban planning is provided by Chantal Mouffe's critique of Habermasian communicative theory and consensus politics, which she bases on her theory of agonistic pluralism. Following Mouffe, to achieve a productive agonistic politics, any rigid antagonisms between “enemies” need to be moderated to more mutable “adversarial” positions. However, we have little knowledge of the conditions that might precipitate such a change in praxis. To address this gap between theory and praxis, we use focus group data to show how local resident action groups and urban alliances work through three modalities of antagonism to achieve their urban development goals. We add empirical weight to the idea that citizens can shift from rigid and fundamental antagonisms to the potentially more productive adversarial politics of agonistic pluralism but therein expose some limitations with how Mouffe's ideas are being applied to urban planning.     

Empirical convection models for northward IMF

It is clear that polar cap convection during times of northward IMF is more structured and of lower mean speed than at times of southward IMF. This, coupled with the fact that the polar cap is smaller, means that empirical models are more difficult to construct with certainty. It is also clear that sunward flow deep in the polar cap is often observed, but its connection with the rest of the flow pattern is controversial.At present, empirical models are of three types: ‘statistical’ models wherein data from different days but with similar IMF conditions are averaged together; ‘pattern recognition’ models, which are built up by examining individually hundreds of passes to derive a ‘typical’ pattern which embodies features frequently observed; and ‘assimilative’ models, which use data of different types and from as many locations as possible, but all taken at the same time, in order to derive a snapshot (or series of snapshots) of the entire pattern.Each type of model has its own difficulties. Statistical models, by their very nature, smooth out flow features (e.g. the convection reversal, and the locus of sunward flow deep in the polar cap) which are not found at precisely the same invariant latitudes and magnetic local times on different days. Pattern recognition models are better at reproducing small-scale features, but the large-scale pattern can be a matter of interpretation. Assimilative models (such as AMIE) hold out the best hope for creating instantaneous, global convection patterns; however, the analysis technique tends to be most irregular (and least reliable) in the regions which are not well covered by in situ data. It appears that, at least at times, a four cell model with sunward flow at the highest and lowest latitudes, and antisunward flow in between, is consistent with the observations. At other times, the observations may be consistent with a two-cell convection pattern, but which includes significant meanders within the polar cap.
