Spatial skill concentration agglomeration economies

Using the Brazilian census and administrative panel data, the present paper provides evidence that the spatial concentration of analytical skills generates positive wage externalities for all workers in the local labor market. We rely on shift‐share instrumental variables to overcome the endogeneity of skill concentrations. The observed externality is independent from the classical market size economies. The estimates are robust to geography, institutions and workers' sorting on unobservable abilities.     

城乡结合部人居环境与经济协调发展分析——以北京市朝阳区为例

疏解非首都功能背景下,北京市的城乡结合部面临调整经济结构与改善人居环境的机遇和挑战。本文以朝阳区为例,结合定量分析与定性讨论,聚焦人居环境与经济系统的协调性问题,剖析协调水平变化的时空间特征及原因。研究发现：2010—2019年期间,朝阳区城乡结合部人居环境与经济系统的协调水平上升明显,空间均衡性有所提升,协调状态呈现出从人居环境滞后过渡到经济系统滞后的演变过程。疏解非首都功能及相关政策是影响协调状态演变的重要因素,它提高了人居环境质量,引发了经济系统的动态调整,短期内使协调水平发生了较大波动,随着人居环境改善幅度逐渐超过经济系统,协调水平出现了下降趋势。提高城乡结合部的可持续发展能力,应重点关注人居环境与经济系统的协调性问题,兼顾地区人居环境改善与经济发展的需求。     

Exploring the context and elements of local environmental stewardship: An embedded case study of the Niagara Region,Canada

Environmental stewardship—a concept that describes the relationships between humans and the environment—is gaining increased attention as an approach that can address planetary sustainability issues. In-depth empirical investigations of local environmental stewardship are needed to understand how social-ecological context influences stewardship, as well as the arrangement of conceptual elements in applied settings. This study addresses these needs by conducting an in-depth exploration of environmental stewardship in the Niagara Region of Canada. A single embedded case study design is employed, with environmental stewardship initiatives constituting the individual units of analysis with the case. Analysis of the spatial arrangement of a total of 89 initiatives indicated that initiatives tended to cluster closer to the Niagara River and in more populous municipalities. The significance of collaboration, tensions between the environment and economic development, and concerns about political impacts emerged as themes across contextual factors. The configuration of stewardship elements reveals interesting discrepancies between initiatives and previous stewardship research focused on larger scales, individuals, and organizations. Further analysis is encouraged to illuminate environmental stewardship in other settings as well as advance relational understanding of conceptual elements.     

HUME,HISTORY, AND THE USES OF SYMPATHY

This article focuses on the role of sympathy and antipathy in David Hume's History of England (1754–1762) in relation to the broader place of sympathy in Hume's moral philosophy. Hume, in his earlier philosophical work, argues that sympathy is a naturally occurring responsiveness to others’ feelings, similar to the resonance between musical strings. In his History, however, he carefully curates his readers’ emotional responses, inviting sympathy with figures of suffering—such as King Charles I and Mary Queen of Scots—while also, often almost simultaneously, stirring intense antipathy for those whose religious extremism he regards as socially dangerous and beyond comprehension. After first situating the emergence of Hume's theory of sympathy in its early eighteenth-century context, this article explores in detail the techniques of sentimental management that appear across the six volumes of the History of England. The elaborate deployment of emotions in Hume's historiography is shown to be in tension both with some aspects of his philosophy of natural human sympathy and with his brief reflections on the writing of history. Hume channeled his readers’ sympathies toward particular targets and against others. A careful analysis of this usefully sheds light on the management of sympathy in modern historiography, on which Hume has had an enduring influence.     

Anatomy,behavior, and modern human origins

The fossil record suggests that modern human morphology evolved in Africa between 150,000 and 50,000 years ago, when the sole inhabitants of Eurasia were the Neanderthals and other equally nonmodern people. However, the earliest modern or near-modern Africans were behaviorally (archaeologically) indistinguishable from their nonmodern, Eurasian contemporaries, and it was only around 50,000-40,000 years ago that a major behavioral difference developed. Archaeological indications of this difference include the oldest indisputable ornaments (or art broadly understood); the oldest evidence for routine use of bone, ivory, and shell to produce formal (standardized) artifacts; greatly accelerated variation in stone artifact assemblages through time and space; and hunting-gathering innovations that promoted significantly larger populations. As a complex, the novel traits imply fully modern cognitive and communicative abilities, or more succinctly, the fully modern capacity for Culture. The competitive advantage of this capacity is obvious, and preliminary dates suggest that it appeared in Africa about 50,000 years ago and then successively in western Asia, eastern Europe, and western Europe, in keeping with an African origin. Arguably, the development of modern behavior depended on a neural change broadly like those that accompanied yet earlier archaeologically detectable behavioral advances. This explanation is problematic, however, because the putative change was in brain organization, not size, and fossil skulls provide little or no secure evidence for brain structure. Other potential objections to a neural advance in Africa 50,000-40,000 years ago or to the wider Out-of-Africa hypothesis, include archaeological evidence (1) that some Neanderthals were actually capable of fully modern behavior and (2) that some Africans were behaviorally modern more than 90,000 years ago.     

Investigating Human Migration and Horse‐Trading in Yelang (夜郎) Through Strontium Isotope Analysis of Skeletons from Zhougshui Sites,South‐West China (1300 bc – ad 25)

Yelang (夜郎), a mysterious state located in the south‐western area of early China and dating from the Bronze Age to the Early Iron Age (1300 bc – ad 25), is a cultural interactive junction between the Yunnan–Guizhou Plateau and the Yangtze River Basin. The Zhongshui Basin in Weining County, Guizhou Province, was one of the important distribution areas of the Yelang civilization. This area, which includes sites at Jigongshan (鸡公山; 1300 – 800 bc ), Hongyingpan (红营盘; 700 – 400 bc ) and Yinzitan (银子坛; 400 bc – ad 25), has provided a very integrated chronology, spanning from the Bronze Age to the Early Iron Age in the eastern Yunnan – western Guizhou area. To investigate human migration and horse‐trading at these Yelang sites, we conducted a strontium isotopic analysis on the teeth enamel of humans and horses unearthed from these three sites. The results indicated the following: (1) people at the earlier sites (Jigongshan and Hongyingpan) were all indigenous, whereas in the Yinzitan cemetery, there was a more immigrant population, and all the people who were buried in an upper limb flexed supine position were non‐local; and (2) most of the horses found at the Jigongshan and Yinzitan sites show different provenances, probably related to the famous Dian (滇) and Zuo (筰) horses recorded in historical documents, providing more clues for further study on horse‐trading in South‐West China during the Bronze Age and the Early Iron Age.     

Rethinking the Politics–Religion Distinction

William T. Cavanaugh argues that the politics–religion distinction presupposes covert commitments that inappropriately support a “migration of the holy” from the church to the state. Despite his strong critical instincts, several of his genealogical propensities appear to stand in tension with his commitments to constitutional democracy and the universality of grace. By contrast with Cavanaugh, John Rawls’ post-metaphysical reformulation of the politics–religion aims to identify a public criterion compatible with a plurality of comprehensive doctrines. Although I commend Rawls for retaining some form of this distinction, I question the possibility of a post-metaphysical standpoint and its compatibility with his commitment to what he calls the “fact of pluralism.” Drawing on Bernard Lonergan’s transpositions of human nature and grace in this paper’s final section, I develop an alternative account of the relationship between politics and religion that aims to harmonize some of the strongest insights from the work of Cavanaugh and Rawls.     

The Ereğli E Shipwreck,Turkey: an early Hellenistic merchant ship in the Black Sea

A shipwreck from the early 3rd century BC was discovered in the Black Sea's suboxic depths off Ere?li, Turkey, during the 2011 E/V Nautilus expedition. Remote investigation revealed the trawl‐damaged remains of a merchant ship carrying multiple amphora types associated with Aegean and Pontic production areas. Also discovered were elements of the ship's hull that show evidence of both pegged mortise‐and‐tenon and laced construction. The wreck provides crucial archaeological evidence for both maritime connectivity and ship‐construction methods during a period of political and economic transition.     

Pre-Columbian Amerindian Lifeways at the Sabazan Site,Carriacou, West Indies

Recent excavations at the Ceramic Age village site of Sabazan on Carriacou, Grenada, indicate long-term occupation spanning AD 400 to 1400. One of the earliest settlements in the Grenadines Archipelago, Sabazan's chronology corroborates late Saladoid colonization of the region with the timing of major developments at this location supported by a robust chronology of 26 radiocarbon assays. Investigation of deep, stratified midden deposits yielded abundant ceramic, shell, and stone artifacts, faunal remains, and burial and domestic features. Zooarchaeological evidence indicates a heavy reliance on marine resources and a well-developed tuna (Scombridae, Thunnini) fishery. While data point to sustainable resource exploitation over a millennium, shifts in foraging strategies are evident, including declines in the fish catch and increasing reliance on large or easily acquired mollusks, particularly queen conch (Lobatus gigas) and nerites (Nerita spp.). These trends may be driven by the greater aridity and warmer sea surface temperatures of the Medieval Warm Period (ca AD 900–1300). Exotic artifacts and the remains of introduced mammals at Sabazan provide evidence for inter-island and continental interactions. Here, I synthesize these findings and their significance for reconstructing West Indian colonization, tracing exchange and interaction networks, and understanding human ecodynamics and long-term adaptation to small island ecosystems.
