Local Indicators of Spatial Association—LISA

The capabilities for visualization, rapid data retrieval, and manipulation in geographic information systems (GIS) have created the need for new techniques of exploratory data analysis that focus on the “spatial” aspects of the data. The identification of local patterns of spatial association is an important concern in this respect. In this paper, I outline a new general class of local indicators of spatial association (LISA) and show how they allow for the decomposition of global indicators, such as Moran's I, into the contribution of each observation. The LISA statistics serve two purposes. On one hand, they may be interpreted as indicators of local pockets of nonstationarity, or hot spots, similar to the G_i and G*_i statistics of Getis and Ord (1992). On the other hand, they may be used to assess the influence of individual locations on the magnitude of the global statistic and to identify “outliers,” as in Anselin's Moran scatterplot (1993a). An initial evaluation of the properties of a LISA statistic is carried out for the local Moran, which is applied in a study of the spatial pattern of conflict for African countries and in a number of Monte Carlo simulations.     

The Religion of the Secularists

Both “religion” and “secularism” are constructs distinctive of the West. They both arise from the peculiar history of Christianity. Hence the double face of modern “religion.” It may cover any inherited cultic practice, safeguard ethnic values, and be respected under multiculturalism. But at the same time it may refer to the intellectual and moral commitments which mark us off socially from others, annoying the secularists. Julian, the first modern‐type secularist, reacted against the Constantinian establishment of the “new religion” by ordering the priests of the old Hellenic cults to adopt the Christian style of social indoctrination to outclass those vulgar innovators. But the Fall of Rome produced the intellectual masterpiece of Augustine which redefined the saeculum and set the framework of modern secularity. Augustine had perceived reality in three dimensions: cosmic, social, and personal. At each level the rationalising logic of Aristotelian science had fixed the pattern of things, by analogy. The whole must be coherent if it is to be true. But the empiricism of Jerusalem had delivered a universe open to change and likely to end. In society power was no longer the proof of virtue. The heart itself was deceptive. Twenty‐first century secularism insists upon such experimental truth, social choice and passionate commitment. This holy trinity is our legacy from the “new” religion.     

An Economic Reading of the Exodus: On the Institutional Economic Reconstruction of Biblical Cooperation Failures

In difference to Genesis, in Exodus interactions between Egypt and Israel broke down. The paper argues that Moses and pharaoh acted like “rational fools” when they escalated problems regarding industrial relations and common pool resources. Pluralism was not mastered as an interaction condition in cross-cultural, “inter-national” relations. The paper explores these issues through the concept of the prisoners' dilemma, in which mutual loss is the outcome. The unsuccessful ordering of economic institutions (governance structures, property rights arrangements, reward systems) is suggested as the key source of conflict. In this way, the paper develops the thesis that the Bible can be read as an economic text which instructs the organisation of human interactions in rational, economic terms. The exodus is not analysed in a more conventional, theological tradition as the resolution of conflict over religious values and the escape of Israel from a claimed system of slavery     

折中的“重估”

“重新估定一切价值”(Transvaluation of all Values),在1919年被胡适用以概括“新思潮的根本意义”,成为新文化运动的重要口号。该口号的提出本有特殊语境。一战后的中国思想界有了新的趋向,尊西趋新、反传统已不再具有类似“政治正确”的独尊地位,原本被尊崇的“欧化”、被否定的“国故”都面临重估。在此背景下,《新青年》派与《时事新报》同人关于“外国偶像”与“固有文化”的争论,成为傅斯年、胡适调整表述的契机,促使他们使用更折中、开放的口号——“重新估定一切价值”“整理国故”来回应对方质疑,并容纳多元的新派。在这一情境中提出及流行的“重新估定一切价值”具有多重属性:胡适在表述上统合种种不一致的新思潮,又暗藏其对中西文化的主张,并针对新兴的“主义”;因其开放性,它在流传中更被不同地理解与使用。这一口号的多重性体现出历史上的五四新文化运动比以往认知的更为丰富。     

7. SPACES,PLACES, AND THE HISTORIANS: A COMMENT FROM A GERMAN PERSPECTIVE

This article discusses from a specifically German point of view the “spatial turn” in history and the approaches of this forum. Many recent interventions have suggested that “space” (as opposed to “time”) was for many years a marginalized category in the German historiographical debate because of the ideological contamination of the category “space” by the Nazis. In the context of the vivid, lively “provincial” or “regional” history practiced in Germany, however, “space” has always played an important role. The debates around the spatial turn nevertheless provide the opportunity for deliberate reconceptualization. This comment proposes a relational understanding of “space” as the core of the new approach and identifies some central elements and terms for it: the differentiation of “spaces,”“places,” and “locations”; movement in space; the division of space in the form of boundaries; finally, the ordering and classification of space in the form of written or visual representations.     

THE CONTINUING MODESTY OF HISTORY

The critique of conventional historical writing has been emergent for a century—it is not the work of a few—and it has immense practical implications for Western society, perhaps especially in English‐speaking countries. Involved are such issues as the decline of representation, the nature of causality, the definitions of identity or time or system, to name only a few. Conventional historians are quite right to consider this a challenge to everything they assume in order to do their work. The challenge is, why do that particular work at all? Understandably, historians have consolidated, especially in North America where empiricism and the English language prevail. But even there, and certainly elsewhere, and given the changes in knowledge and social order during the past century at least, the critique of conventional historical method is unavoidable. Too bad historians aren't doing more to help this effort, and by historians I don't mean the most of us who think constantly in terms of historical causality as we learned it from the nineteenth century and our teachers; by “historians” I mean the experts who continue to teach the young. A major roadblock to creative discussion is the fact that problems such as those just mentioned all exceed disciplinary boundaries, so investigation that does not follow suit cannot grasp the problem, much less respond to it creatively. Of course everyone is “for” interdisciplinary work, but most professional organizations, publications, and institutions do not encourage it, despite lip service to the contrary. Interdisciplinary work involves more than the splicing activity that is all too familiar in academic curricula. Crossing out of one's realm of “expertise” requires a kind of humility that does not always sort well with the kind of expertise fostered by professional organizations, publications, and institutions. And even the willing have trouble with the heady atmosphere outside the professional bubble. In such conditions key terms (“language,”“discourse,”“relativism,”“modernity,”“postmodernity,”“time,”“difference”) are pushed here and pushed there without gaining the focus that would lead to currency until finally the ostensible field of play resembles a gigantic traffic jam like the one that opens the film Fellini Roma. Discussion of these issues leads in the end to Borges and his story, ‘The Modesty of History,” from which the title of this essay is borrowed.     

Effect(s) of the “No-Same-Color-Touching” Constraint on the Join-Count Statistic: A Simulation Study

The join-count statistic is used to measure the tendency of polygons of a given map type to attract or repel polygons of the same or different map types. Yet in certain maps—for example, natural resources maps—it is often impossible for a polygon of a given type to touch another polygon of the same type. (This is the no-same-color or “No-Same-Type-Touching” (NSTT) constraint referred to in the title.) This violates an underlying assumption of the join-count statistic and may render its use to study certain spatial phenomena inappropriate—even for measuring spatial autocorrelation among polygons that are not the same type. This was explored using Monte Carlo simulation. For polygons of different types, it appears that results of the join-count statistic can be interpreted without any special consideration for the NSTT constraint provided there are a minimum of five to eight colors in the spatial system. For polygons of the same type, results can simply be ignored since it is known that no two polygons of the same type will touch.     

Beyond Moran's I: Testing for Spatial Dependence Based on the Spatial Autoregressive Model

The statistic known as Moran's I is widely used to test for the presence of spatial dependence in observations taken on a lattice. Under the null hypothesis that the data are independent and identically distributed normal random variates, the distribution of Moran's I is known, and hypothesis tests based on this statistic have been shown in the literature to have various optimality properties. Given its simplicity, Moran's I is also frequently used outside of the formal hypothesis-testing setting in exploratory analyses of spatially referenced data; however, its limitations are not very well understood. To illustrate these limitations, we show that, for data generated according to the spatial autoregressive (SAR) model, Moran's I is only a good estimator of the SAR model's spatial-dependence parameter when the parameter is close to 0. In this research, we develop an alternative closed-form measure of spatial autocorrelation, which we call APLE , because it is an approximate profile-likelihood estimator (APLE) of the SAR model's spatial-dependence parameter. We show that APLE can be used as a test statistic for, and an estimator of, the strength of spatial autocorrelation. We include both theoretical and simulation-based motivations (including comparison with the maximum-likelihood estimator), for using APLE as an estimator. In conjunction, we propose the APLE scatterplot, an exploratory graphical tool that is analogous to the Moran scatterplot, and we demonstrate that the APLE scatterplot is a better visual tool for assessing the strength of spatial autocorrelation in the data than the Moran scatterplot. In addition, Monte Carlo tests based on both APLE and Moran's I are introduced and compared. Finally, we include an analysis of the well-known Mercer and Hall wheat-yield data to illustrate the difference between APLE and Moran's I when they are used in exploratory spatial data analysis.     

明末关宁军性质的再讨论——以“祖家将”为核心的观察视角

通过对“祖家将”这一关宁军中较为重要的武将集团在关宁军中地位之演变可知,天启年间“祖家将”在关宁军中的地位较低。袁崇焕督师辽东期间,祖大寿因战功擢升为总兵,在大凌河之战后,祖大寿的地位得以稳固,随即发展个人势力。但应看到,“祖家将”在关宁军中始终没有占据绝对主导地位,明廷对关宁军控制较深。因此,“家军”、“将门”的方式,不能完全用来揭示关宁军的性质,不能将关宁军简单界定为独立于明廷的军阀武装。     

Innocence et puissance Heidegger face au principe de raison

The principle of reason, that is accounting for all things by referring them to an unquestioned, fundamental principle, commands for Heidegger the total mobilization and universal computation of the world by the technical. The critique of this principle seems to lead Heidegger toward a thinking of the relinquishment of things and an epistemology of innocence, freed from any effect of metaphysical, political, or sociological power. That innocence is however ambiguous. It recalls the Heraclitean play of the child-king and announces the return of a mysterious sovereignty. The power of the technical is warded off for the benefit of another power, not less commanding and absolute, a “superpower” which in its turn could effectively mean, in a still more decisive way than the becoming-technical of thinking, the accomplishment and the end of metaphysics.     

Buddhism,Democracy and Power in the 1932 Thai Revolution

The People’s Party toppled the Siamese absolute monarchy and introduced constitutional democracy in Thailand in June 1932. Scholars have generally denied that the revolution had any popular resonance, but this article shows that in Buddhism, the country’s premier cultural form, democratic rhetoric in the 1930s resonated among young monks marginalised by the ecclesiastical hierarchy. A group of young monks within the Mahanikai, or Great Order, rebelled against the palace-established Thammayut order that exercised the most power in institutional Buddhism. A “thin” or formal democracy established in 1932 – one displaying the main trappings of a regime of popular sovereignty but purposefully limited in scope by the People’s Party – thus inspired an assertion of a “thick” democracy, or democracy as a much older social value that governed both the Sangha internally and its relations with local communities, which the Mahanikai activists claimed was the core of original Buddhism.

     

Capitalism's Anxious Whole: Fear,Capture and Escape in the Grundrisse

Abstract: Two Hegels inhabit the Grundrisse. The first is conservative of the “selfsame” subject that continuously returns to itself as non‐identical identity and propels “history”. The other Hegel tarries with the “negative” he (which or variously calls “non‐being”, “otherness”“difference”) to disrupt this plenary subject to Marx's reading of a Hegel who is different‐in‐himself lends Grundrisse its electric buzz: seizing Hegel's “negative” as the not‐value of value, i.e. “labor”, Marx explains how capital must continuously enroll labor to its will in order to survive and expand. But this enrollment is never given; hence, despite its emergent structure of necessity, capital's return to itself as “self‐animating value” is never free of peril. The most speculative aspect of my argument is that the figure of “labor” in Grundrisse, because of its radically open formulation as not‐value, anticipates the elusive subject of difference in postcolonial theory, “the subaltern”—that figure which evades dialectical integration, and is in some ontological way inscrutable to the “master”. Unexpectedly, then Grundrisse gives us a way to think beyond the epistemic and geographic power of “Europe”.     

Unsightly urban menaces and the rescaling of residential segregation in the United States

In this article, the author uses a slum clearance project in Lexington, Kentucky, as a lens through which to examine the spatial dynamics of racial residential segregation during the first half of the twentieth century. At the time, urban migration and upward socioeconomic mobility on the part of African Americans destabilized extant residential segregation patterns. Amid this instability, various spatial practices were employed in the interest of maintaining white social and economic supremacy. The author argues that such practices were indicative of a thoroughgoing reinvention of urban socio-spatial order that in turn precipitated the vastly expanded scale of residential segregation still found in U.S. cities today. Evidence of this reinvented ordering of urban space lies in the rendering of some long-standing African American neighborhoods as “out of place” within it and the use of slum clearance to remove the “menace” such neighborhoods posed to it.     

Explaining "Auschwitz" after the End of History: The Case of Italy

Everywhere the 1990s have been characterized by an odd mixture of ideological triumphalism—Fukuyama's “end of history” being only the crassest example—and of ideological uncertainty—can there be, should there be, a “third way”? For all its pretensions to universality, the “New World Order” has never lost a fragility in appearance. Students of historiography can scarcely be surprised to learn that an uneasiness over the present and future has in turn frequently entailed uncertainty about the past and particularly about those parts of the past which had seemed most able to give clear and significant “lessons.” One evident example is the history of what in my Explaining Auschwitz and Hiroshima (1993) I called the “long” Second World War, that is, that crisis in confidence in the relationship between political and economic liberalism and the nation-state which, by the end of 1938, had left only Britain, France, the Low Countries, and Scandinavia as in any sense preserving those “liberal” freedoms which had spread across Europe since 1789. In this article, I briefly review the most recent difficulties World War II combatant societies have had in locating a usable past in the history of those times. However, my major focus is on the specific case of Italy, very much a border state in the Cold War system, and today the political home of an “Olive Tree” and a “Liberty Pole” whose historical antecedents and whose philosophical base for the future are less than limpid. 1990s Italian historians thus give very mixed messages about the Fascist past; these are the messages I describe and decode.     

DEFORMATION-CONTROLLED EARTHQUAKE-RESISTANT DESIGN OF RC BUILDINGS

A procedure for deformation-controlled, or displacement-based, seismic design of multistorey RC buildings is proposed, implemented and applied for the full design of a four-storey RC structure. It is integrated into the overall structural design, along with the design for the non-seismic actions and consists of a ULS verification against the conventional strain limits for a frequent “serviceability” earthquake and of proportioning the compression reinforcement and the transverse reinforcement of critical regions of members to meet the member peak inelastic chord rotation demands under the “life-safety” seismic action. Quantitative rules and expressions are proposed for the estimation of (a) mean and upper-characteristic peak inelastic chord rotation demands, through appropriate linear-elastic analyses, and (b) mean and lower-characteristic values of member ultimate chord rotations, in terms of member geometric and material data.     

Observing,Collecting and Governing “Ourselves” and “Others”: Mass-Observation's Fieldwork Agencements

This paper explores the relationship between oligoptic visual economies and liberal technologies of government which emerge from a consideration of the field collecting practices of Mass-Observation (MO), a social research movement established in the years leading up to the outbreak of the Second World War which attempted to develop an anthropology of British “everyday” life. Focussing on MO's fieldwork agencements, the paper shows how the project brought together museological methods of collecting and curating with new mechanisms of collective self-watching, and the ways in which these mechanisms became implicated in technologies of government through its archival operations. In the connections it drew between the liberal subjectivities of collective self-watching and surrealist aesthetic practices, MO played a significant role in shaping new governmental rationalities, with implications for both metropolitan and colonial populations, through its interlinked conceptions of “mass” and “morale”. These formed part of a broader scientific–administrative–bureaucratic apparatus which facilitated the classification, ordering and governance of populations and “things” in this and later periods.     

MEDIAN,MEAN, AND OPTIMUM AS FACILITY LOCATIONS*

ABSTRACT The mean and the median are both measures of centrality. In one dimension, the median minimizes the average absolute distance from a facility to a set of customers {x_i}, and the mean minimizes the average squared distance. In two dimensions, the median minimizes the average rectangular distance, and the mean minimizes the average squared distance. This paper investigates the “location penalty” when a nonoptimal location is substituted for the optimal location. In one dimension, the average absolute distance at the mean is never more than twice the average absolute distance at the median. Surprisingly, this happens when the median and mean are close together. In two dimensions, the ratio of the average Euclidean distance at the median to the average Euclidean distance at the optimum is never more than . However, this upper bound depends on an unlikely scenario with just two customers. With three equal-sized customers, this ratio is never more than 1.12. However, if the triangle formed by the customers is rotated relative to the rectangular grid, the ratio never exceeds 1.028.
