Cities in a pandemic: Evidence from China

This paper studies the impact of urban density, city government efficiency, and medical resources on COVID-19 infection and death outcomes in China. We adopt a simultaneous spatial dynamic panel data model to account for (i) the simultaneity of infection and death outcomes, (ii) the spatial pattern of the transmission, (iii) the intertemporal dynamics of the disease, and (iv) the unobserved city-specific and time-specific effects. We find that, while population density increases the level of infections, government efficiency significantly mitigates the negative impact of urban density. We also find that the availability of medical resources improves public health outcomes conditional on lagged infections. Moreover, there exists significant heterogeneity at different phases of the epidemiological cycle.     

Women's Empowerment Through Home–based Work: Evidence from India

This article examines the extent to which home–based production in the garment sector of Ahmedabad, India, serves to empower its female participants, defining empowerment in terms of control over enterprise income and decision–making within the household. It places this question within the literatures on resource theory and bargaining models of the household, both of which posit that improved access to resources increases women's power in the household. This study highlights why access to resources may not lead so directly to improvements in women's position in the household in the Indian context. It then discusses why home–based work may be less empowering than sources of work outside of the home. The arguments about the empowerment potential of women's access to resources through home–based work are tested by examining, first, the determinants of control over the income generated by women in home–based garment production and, second, to what extent access to and control over income from this source translates into involvement in decisions which are atypically women's and yet important to their lives. The results provide a better understanding of the potential of home–based work to offer women in urban India a source of economic activity that also can translate into increased intra–household power.     

Complex Contagions and the Diffusion of Innovations: Evidence from a Small-N Study

The recent literature on “complex contagions” challenges Granovetter’s classic hypothesis on the strength of weak ties and argues that, when the actors’ choice requires reinforcement from several sources, it is the structure of strong ties that really matters to sustain rapid and wide diffusion. The paper contributes to this debate by reporting on a small-N study that relies on a unique combination of ethnographic data, social network analysis, and computational models. In particular, we investigate two rural populations of Indian and Kenyan potters who have to decide whether to adopt new, objectively more efficient and economically more attractive, technical/stylistic options. Qualitative field data show that religious sub-communities within the Indian and Kenyan populations exhibit markedly different diffusion rates and speed over the last thirty years. To account for these differences, we first analyze empirically observed kinship networks and advice networks, and, then, we recreate the actual aggregate diffusion curves through a series of empirically calibrated agent-based simulations. Combining the two methods, we show that, while single exposure through heterophilious weak ties were sufficient to initiate the diffusion process, large bridges made of strong ties can in fact lead to faster or slower diffusion depending on the type of signals circulating in the network. We conclude that, even in presence of “complex contagions,” dense local ties cannot be regarded as a sufficient condition for faster diffusion.     

Social Protection and Class Relations: Evidence from Scheduled Caste Women's Associations in Rural South India

This article argues that the labouring class poor are best able to access social protection when they have sufficient economic autonomy from their village's dominant class to allow them to act politically. To this end, the article analyses the capacity of associations of scheduled caste female labourers in rural Karnataka (south India) to access social protection through collective action. It identifies links between modifications of the material conditions of the labouring class, their capacity to take political action and the social and institutional forms that reflect the social relations of production. Three important variables are identified: the extent of economic autonomy from the dominant class, support from class‐conscious social movement organizers and the political configuration of the local state. The former variable in particular is something that the mainstream social protection policy agenda fails to prioritize.     

Analyzing Hotspots of Crime Using a Bayesian Spatiotemporal Modeling Approach: A Case Study of Violent Crime in the Greater Toronto Area

Conventional methods used to identify crime hotspots at the small‐area scale are frequentist and employ data for one time period. Methodologically, these approaches are limited by an inability to overcome the small number problem, which occurs in spatiotemporal analysis at the small‐area level when crime and population counts for areas are low. The small number problem may lead to unstable risk estimates and unreliable results. Also, conventional approaches use only one data observation per area, providing limited information about the temporal processes influencing hotspots and how law enforcement resources should be allocated to manage crime change. Examining violent crime in the Regional Municipality of York, Ontario, for 2006 and 2007, this research illustrates a Bayesian spatiotemporal modeling approach that analyzes crime trend and identifies hotspots while addressing the small number problem and overcoming limitations of conventional frequentist methods. Specifically, this research tests for an overall trend of violent crime for the study region, determines area‐specific violent crime trends for small‐area units, and identifies hotspots based on crime trend from 2006 to 2007. Overall violent crime trend was found to be insignificant despite increasing area‐specific trends in the north and decreasing area‐specific trends in the southeast. Posterior probabilities of area‐specific trends greater than zero were mapped to identify hotspots, highlighting hotspots in the north of the study region. We discuss the conceptual differences between this Bayesian spatiotemporal method and conventional frequentist approaches as well as the effectiveness of this Bayesian spatiotemporal approach for identifying hotspots from a law enforcement perspective.     

The Study of a System of Cities of the Soviet Union

Odessa's advantageous economic-geographic situation has played a positive role in all phases of the city's development. It has promoted Odessa's pre-eminent place as a foreign trade center and its function as a key element in the geographical division of labor. The situational advantages of the city should be taken into account in any historical-geographic study and in insuring more rational economic relations between the city and the rest of the Soviet Union.     

Assessing Effectiveness of Veto Threats in the Bush Administration (1989-1993): Preliminary Evidence from Case Studies

Presidents have many tools in the policy-making process. One of the most powerful of these is vetoing legislation. Although presidents can veto legislation at will, the use of the veto is costly as it can be perceived as a sign of weakness. Veto threats may provide the president with a bargaining tool relying on the power of the veto without incurring its costs. This article provides a framework for understanding the use and effectiveness of veto threats. First, the present understanding of the use of veto threats is discussed, including the conditions under which they are most likely to occur and to be effective. Next, we provide a conceptualization of the context in which a veto threat is issued and the result of such a threat. Finally, using the Bush administration (1989-1993), we illustrate two possible results with case studies of civil rights and child care legislation.

Maintaining Traditions: a Study of Southern Ontario Late Woodland Ceramics Through a Communities-of-Practice Approach

A communities-of-practices approach has been employed in this paper to investigate potting traditions of Late Woodland potters. The author has integrated Wenger’s (1998, Organization 7(2):225–246, 2000) constellation of practice and boundary objects with Smith’s (1997, 2005a) attribute combination system to study decorative practices of Middle Iroquoian potting communities in southern Ontario. The results of the study indicate similar distribution trends relating to the practice of decorative motifs. The author argues potters maintained potting traditions through time and space. This study demonstrates how the integration of more recent conceptual frameworks provides further opportunities to investigate the relation between pottery production and broader practices and beliefs.     

Looking at Interethnic Relations in the Southern Border Through Glass Remains: The NineteenthCentury Pampa Region,Argentina

Arroyo Nieves 2 is an open-air site located in a ravine of a small stream in the Pampa region. Its stratigraphy and archaeological remains assigned it to an aboriginal occupation dated in the third quarter of the nineteenth century. At the time, some indigenous groups were settled in strategic borderline areas by the government, on the basis of reciprocal rights and duties. Food and other supplies were given to the Indians to avoid cattle and women raids, thereby keeping the peace. The findings at Arroyo Nieves 2 include bones, from both domestic and wild species, lithic instruments and debris, fragments of stoneware bottles, refined earthenware sherds, buttons, small pieces of metal and numerous glass remains from wine, beer, bitter, and gin bottles, flasks, glasses, and food containers. This paper presents a study of the glass remains, data that have proven to provide evidence on a wide range of themes, including chronology, trade networks and activities, consumption behaviors, and discard patterns.     

Infrastructure and Growth in a Spatial Framework: Evidence from the EU regions

This paper examines the return to infrastructure in the European Union regions in a spatial framework. It innovates on the earlier literature on infrastructure and growth by a combination of regional focus, disaggregation of infrastructure types and consideration of spatial dependence. Different types of infrastructure capital are considered as determinants of economic performance at the Nomenclature des Unités Territoriales Statistiques level. To account for growth spillovers among regions, a spatial Durbin model is estimated. The results confirm the important role of infrastructure and identify the highest rates of return as associated with telecommunication, quality and accessibility of transportation networks, with a positive impact of roads and railways.

The Relevance of the 'Irrelevant': Football as a Missing Dimension in the Study of British Relations with Germany

This article has been developed and updated from a paper delivered at the Grossbritannien-Zentrum, Humboldt University at Berlin, June 2000. Traditionally, sport has been marginalized, even treated as an irrelevance, in the study of International Relations (IR). The 2002 World Cup Finals raised yet again questions about the realism of continuing to write sport out of IR, and particularly to ignore its impact upon such relationships as those between Britain and Germany. Football's role in mirroring, influencing and articulating British perceptions of Germany, at least at the popular and media level, is presented as a case-study, since the football field proved another important British_German battleground throughout the twentieth century. This trend continues. Already, three high profile football internationals played during 2000–1 as well as rivalry to host the 2006 World Cup tournament have illuminated the problematic state of the British-German relationship, particularly the fact that history, most notably world war imagery, imparts en enduring extra-sporting sub-text for any England-Germany footballing encounter.     

国际关系视角下的博物馆对外展览:作用与挑战

在国际关系视角下,博物馆对外展览既可以被归为服务于一国对外政策的文化外交,也可以被归为致力于长远宏观目标的人文交流.每个对外展览因动因不同,所发挥的作用也不尽相同,但通常作用包括形塑国家形象、搭建沟通桥梁、增进相互理解.与此同时,国内外政治形势、法律框架、国家政策等都是对外展览发生的重要背景和能够发生的决定条件,而展览能否真正改变观众的行为或态度又受到文化偏见的干扰,这就造成了博物馆对外展览影响力的不可控性和缓释性.面对这些挑战,中国博物馆作为民族国家的形象代表,应当致力于在更高层次上将独特性转化成普遍性,以自己的方式表现其他社会和文化同样注重的价值,为推动构建人类命运共同体贡献力量.     

School Vouchers and Student Attainment: Evidence from a State‐Mandated Study of Milwaukee's Parental Choice Program

In this article we examine educational attainment levels for students in Milwaukee's citywide voucher program and a comparable group of public school students. Using unique data collected as part of a state‐mandated evaluation of the program, we consider high school graduation and enrollment in postsecondary institutions for students initially exposed to voucher schools and those in public schools at the same time. We show that exposure to voucher schools was related to graduation and, in particular, to enrollment and persistence in a 4‐year college. These differences are apparent despite controls for student neighborhoods, demographics, early‐career test scores and—for a subsample of survey respondents—controls for parental education, income, religious behavior, and marital status. We conclude by stressing the implications for future scholarship and policy, including the importance of attainment outcomes in educational research.     

The Spatial Dispersion of Informal Investment at a Regional Level: Evidence from the UK

Although there have been various studies on the geographical specialization of venture capital in the UK, there remains a gap in the research on regional differences in the behaviour of those informal investors who make a significant contribution to the funding of entrepreneurial ventures. Utilizing a unique data set from the Global Entrepreneurship Monitor project, this study will estimate the level of informal investment activity across the different regions of the UK. The relationship between informal investment and early stage formal venture capital availability is also examined to determine which areas display the greatest funding gaps in the provision of equity finance. It shows that while formal and informal investments are heavily concentrated in highly prosperous areas such as London and the South East of England, informal investments make a larger relative contribution to early stage and expansion equity capital within poorer regions.     

Controlling for Doubt and Uncertainty Through Multiple Lines of Evidence: A New Look at the Mesoamerican Nahua Migrations

Nahuatl represents a relatively recent extension of the Uto-Aztecan language family into Mesoamerica. Ethnohistorians have linked Nahuatl's arrival to the historically attested migrations of nomadic people into central Mexico in the last centuries before the Spanish Conquest. Archaeologists have tended to treat migration as an explanation for a change in material culture rather than a social question to be examined theoretically. We approach this migration through the comparison of multiple data sets and conclude that what has previously been treated as a historical event is instead part of a longer term process tying together Mesoamerica's northern periphery with its highland core. While we find that certain themes from migration theory are reflected in this preindustrial migration as well, other variables are unique and bode well for archaeology's ability to address and contribute to theoretical issues relating to migration.
