Growth and Convergence in a Multiregional Model with Space–Time Dynamics. 多区域时空动态模型的增长与收敛

The goal of this article is to test four distinct hypotheses about whether the relative location of an economy affects economic growth and economic well‐being using an extended Solow–Swan neoclassical growth model that incorporates both space and time dynamics. We show that the econometric specification takes the form of an unconstrained spatial Durbin model, and we investigate whether the results depend on some methodological issues, such as the choice of the time span and the inclusion of fixed effects. To estimate the fixed effects spatial Solow–Swan model, we adjust the Arrelano and Bond (1991) generalized method‐of‐moments (GMM) estimator to deal with endogeneity not only arising from the initial income level, as in the basic model, but also from the initial income levels and economic growth rates observed in neighboring economies.     

The Ore‐Dressing Grindstone Called a ‘Quimbalete’: a Mechanics‐Based Approach

The ‘quimbalete’ is a kind of grindstone used notably in Potosi (Bolivia) during the Spanish conquest of South America. It was used to grind pieces of ore gravel from centimetric sizes to the size of sand. Its physical functioning, as well as the reason why this strictly Andean tool occupied a central place in a mainly European production chain, have never been addressed. This study is aimed at answering these questions as a result of physics‐based modelling. After introducing the historical context, we address geometrical and physical parameters relevant for understanding how this oscillating grindstone was used and what one can expect in terms of grinding. Then, a suitable approach for estimating the yield makes use of the modern industrial empirical estimator: the ‘power index’. We offer our conclusions about the position of this tool, which appears as an ideal intermediate tool between the roughening process of the ore at the centimetre scale, and the suitable size for the material to be sorted by the subsequent methods in the chain (such as washing), which involve sandy‐sized grains. The study also shows how classical physics can help in addressing questions concerning minerallurgy.     

India's ‘non‐alignment’ conundrum: a twentieth‐century policy in a changing world

The idea of non‐alignment has remained a central component of Indian identity in global politics that is manifest in continuities: since independence in 1947 India has been in pursuit of strategic autonomy, a quest that in practice has led to semi‐alliances fashioned under the cover of non‐alignment and shaped by regional dynamics. In this setting, the rise of China now raises an interesting conundrum for Indian policy‐makers as New Delhi seeks to balance the benefits and risks of an increasingly assertive neighbour and a network of alliances with like‐minded countries. This article approaches this enigma by delineating continuities of non‐alignment from the early roots of the policy, through the Cold War‐era and into the modern‐day international system. Though domestic factors have had a significant influence on the trajectory of Indian foreign policy, the continuities of non‐alignment have prevailed through changes in leadership and domestic vicissitudes. By exploring the foundation of non‐alignment and how India has operationalized the policy, this article maintains that to some extent continuity will persist: India will likely continue its rhetoric in favour of strategic autonomy while moving closer to the West and its allies in practice. Yet in order to effectively balance China's growing influence, India will need to be more assertive in building these alliances, as the success of its modern‐day pursuit of strategic autonomy may well rest on a strong foundation of strategic partnerships. The coming to office in May 2014 of the National Democratic Alliance government led by Narendra Modi has signalled a move away from even the rhetoric of non‐alignment, with significant implications for the future of Indian foreign policy.     

A New Perspective about Moran's Coefficient: Spatial Autocorrelation as a Linear Regression Problem. Moran系数的新视角：空间自相关视为线性回归问题

The computation of Moran's index of spatial autocorrelation requires the definition of a spatial weighting matrix. The eigendecomposition of this doubly centered matrix (i.e., one that forces the sums of all rows and columns to equal zero) has interesting properties that have been exploited in various contexts: distribution properties of the Moran coefficient (MC), spatial filtering in linear models, generalized linear models, and multivariate analysis. In this article, this eigendecomposition is used to propose a new view of MC based on its interpretation in the simple context of linear regression. I use this interpretation to demonstrate the different properties of MC and also the inefficiency of this index in some situations involving simultaneous positive and negative spatial autocorrelation. I propose some new statistics and procedures for testing spatial autocorrelation, and conduct a simulation study to evaluate these new approaches.     

Switzerland as a ‘fractured nation’

ABSTRACT. This article deals with Swiss nationalism and Swiss nation‐building. Its main thesis is that Switzerland cannot accurately be described as either a nation or a non‐nation but is something in between, and could thus best be characterised as a ‘fractured’ nation. Switzerland has experienced some powerful nationalist moments, from the creation of the Swiss state in 1848 to the last few decades. Yet this recurrent nationalism among the Swiss, considered alongside their more traditional reluctance to consider themselves a nation, make Switzerland a peculiar object: a ‘fractured’ nation. This flawed process of nation‐building in turn reveals some basic characteristics of all nations – inherent artificiality, and the tremendous efforts undertaken to hide it. Switzerland could be considered an unfinished, incomplete nation, and this is precisely why its study can be interesting for scholars of nations and nationalism.     

‘Tribalism’ gets a bum rap

Tribalism gets a very uneven press in the US, particularly in the present political climate. Images of tribes as exclusionary and pugnacious are both misleading and injurious. After briefly surveying some of the common misuses of the category, the article suggests that a view of tribes as characterized by their qualities of shape‐shifting, openness, and suspicion of power leads not only to a reconceptualization of a category worth maintaining by anthropologists but a realization, as Justice Cardozo said, that analogies can begin by assisting us only to end by enslaving us.     

A Hybrid Framework for Space–Time Modeling of Environmental Data. 环境数据时空建模的混合框架

The space–time autoregressive integrated moving average (STARIMA) model family provides useful tools for modeling space–time processes that exhibit stationarity (or near stationarity) in space and time. However, a more general method for routine use and efficient computation is needed to model the nonlinearities and nonstationarities of environmental space–time series. This article presents a hybrid framework combining machine learning and statistical methods to address this issue. It uses an artificial neural network (ANN) to extract global deterministic (nonlinear) space–time trends and a STARIMA model to extract local stochastic space–time variations in data. A four‐stage procedure is proposed for analyzing and modeling space–time series. The proposed framework and procedures are applied to forecast annual average temperature at 137 national meteorological stations in China. The results demonstrate that the hybrid framework achieves better forecasting accuracy than the STARIMA model alone. This finding suggests that the combination of machine learning and statistical methods provides a very powerful tool for analyzing and modeling space–time series of environmental data that have strong spatial nonlinear and nonstationary components.

Śāntideva's Bodhicaryāvatāra in Translation: A Century of Interpretation of a Sanskrit Mahāyāna Text

Many translations of ?āntideva's Bodhicaryāvatāra, a Sanskrit Mahāyāna Buddhist text of seventh/eighth‐century India, have been published since 1892. ?āntideva's Bodhicaryāvatāra is one of the few Indian Mahāyāna Buddhist texts available in Sanskrit and it was influential in Tibetan Buddhist schools. This article explores how translation of the Bodhicaryāvatāra is no longer the preserve of scholars but has moved to being carried out by Buddhist practitioners influenced by Tibetan schools of Buddhism. It shows how translators’ motives for translating the text have reflected changing attitudes to Buddhism and its texts. ?āntideva's Bodhicaryāvatāra has been translated as a source of information, a literary work, an inspirational work and, with the rise of Western interest in Tibetan Buddhism in the late twentieth century, as a vehicle for the transmission of Buddhist teachings. Nevertheless, further scholarly investigation of the Sanskrit text of the Bodhicaryāvatāra remains to be done.     

Foucault's and Arendt's "insider view" of biopolitics: a critique of Agamben

This article revisits Arendt's and Foucault's converging accounts of modern (bio)politics and the entry of biological life into politics. Agamben's influential account of these ideas is rejected as a misrepresentation both because it de-historicizes biological/organic life and because it occludes the positivity of that life and thus the discursive appeal and performative force of biopolitics. Through attention to the genealogy of Arendt's and Foucault's own ideas we will see that the major point of convergence in their thinking is their insistence upon understanding biological thinking from the inside, in terms of its positivity. Agamben's assessment of modern politics is closer to Arendt's than it is to Foucault's and this marks a fascinating point of disagreement between Arendt and Foucault. Whereas Arendt sees the normalizing force of modern society as being in total opposition to individuality, Foucault posits totalization and individuation as processes of normation, which casts a light upon the relative import they place upon politics and ethics.     

Determinants of Variation in Population–Employment Interaction Findings: A Quasi‐Experimental Meta‐Analysis. 人口‐就业相互作用的决定因素研究：一种准实验元分析法

This article reports about a metaregression analysis of empirical results generated using data for the northern Netherlands (1988–2002) in order to investigate the ambiguity in results in the population–employment interaction literature. Specifically, the analysis deals with the issue whether “jobs follow people” or “people follow jobs.” The article starts with introducing the basics of quasi‐experimental meta‐analysis and with identifying some advantages of using quasi‐experimental meta‐analysis as compared with the standard meta‐analysis approach. Two subsequent sections document the selection of the population–employment interaction model and salient characteristics of the data set as well as the setup of the primary analyses. A total of 4,050 quasi‐experimental empirical results for the jobs–people direction of causality are generated using different specifications and estimators for a spatial econometric interaction model. The subsequent metaregression analysis reveals that the empirical results are largely shaped by the spatial, temporal, and employment characteristics of the data sampling. The results also appear much more sensitive to different measurements of the model's key variables when compared with alternative specifications of the spatial weights matrix. The main determinant driving empirical results about jobs–people causality are differences in model specification and estimation, as revealed by an inherent bias in parameter estimates and misguided inferences for some of the commonly used specifications. Finally, suggestions for future research are identified.     

The p‐Regions Problem. p‐区域问题

The p‐regions problem involves the aggregation or clustering of n small areas into p spatially contiguous regions while optimizing some criteria. The main objective of this article is to explore possible avenues for formulating this problem as a mixed integer‐programming (MIP) problem. The critical issue in formulating this problem is to ensure that each region is a spatially contiguous cluster of small areas. We introduce three MIP models for solving the p regions problem. Each model minimizes the sum of dissimilarities between all pairs of areas within each region while guaranteeing contiguity. Three strategies designed to ensure contiguity are presented: (1) an adaptation of the Miller, Tucker, and Zemlin tour‐breaking constraints developed for the traveling salesman problem; (2) the use of ordered‐area assignment variables based upon an extension of an approach by Cova and Church for the geographical site design problem; and (3) the use of flow constraints based upon an extension of work by Shirabe. We test the efficacy of each formulation as well as specify a strategy to reduce overall problem size.     

Minority–Majority Relations in the Schelling Model of Residential Dynamics. 住宅动态迁移Schelling模型中的少数‐多数关系

The Schelling model describing segregation between two groups of residential agents, reflects the most abstract, basic view of noneconomic forces motivating residential migrations: be close to people of “your own” kind. The model assumes that residential agents, located in neighborhoods where the fraction of “friends” is less than a predefined threshold value F, try to relocate to neighborhoods where this fraction is F or higher. For groups of equal size, Schelling's residential pattern converges either to complete integration (random pattern) or segregation, depending on F. We investigate Schelling model pattern dynamics as a function of F in addition to two other parameters—the ratio of groups' numbers, and neighborhood size. We demonstrate that the traditional integration–segregation pattern dichotomy should be extended. In the case of groups of different sizes, a wide interval of F‐values exists that entails a third persistent residential pattern, one in which a portion of the majority population segregates while the rest remains integrated with the minority. We also demonstrate that Schelling model dynamics essentially depend on the formalization of urban agents' residential behavior. To obtain realistic results, the agents should be satisficers, and the fraction of the agents relocating irrespective of the neighborhood's state should be nonzero. We discuss the relationship between our results and real‐world residential dynamics.     

A Theory‐Based Cellular Automata for the Simulation of Land‐Use Change. 基于理论细胞自动机的土地利用变化模拟

This study proposes a theory‐based cellular automata (CA) in which CA rules are constructed on the basis of a theory of urban land‐use change and other local conditions. Rent gap theory that describes urban redevelopment and exogenous conditions that reflect urban development are embedded into a CA to simulate changes of land use. The theoretical framework provides a strong conceptual background for the CA simulation. A case study demonstrates the flexibility of the integrated framework for simulating land‐use changes in complex settings. This research aims to help decision‐makers formulate appropriate development plans.     

IN THE FOLDS OF TIME: RASHĪD AL‐DĪN ON THEORIES OF HISTORICITY

By focusing on Rashīd al‐Dīn's (d. 718/1318) historiographical oeuvre and here in particular his “History of the World,” this article challenges the usual approach to his Jāmi? al‐tawārīkh (Compendium of Chronicles) and argues that his was a deeply pluralistic enterprise in a world with many centers, tremendous demographic change, high social mobility, and constantly shifting truth‐claims in an ever expanding cosmos, to which Rashīd al‐Dīn's method, language, and the shape of his history were perfectly adaptable. This article introduces the notion of “parallel pasts” to account for Rashīd al‐Dīn's method. By placing the Jāmi? al‐tawārīkh and its author in their historical and intellectual context, this article also argues that this method is not restricted to Rashīd al‐Dīn's historiography: His historiographical work ought to be seen as part of his larger theological and philosophical oeuvre into which the author placed it consciously and explicitly, an oeuvre that is, like Rashīd al‐Dīn's historiography, pluralist at heart, and that could be as easily classified as “theology” or “philosophy” as “historiography.”
