衣及权力:明代中国的礼仪、服装与国家权威

As soon as Zhu Yuanzhang, the founder of the Ming Dynasty, assumed the throne, he and his Confucian assistants imposed a system of clothing regulation on the court and society in order to create a hierarchical power structure. As an important aspect of Chinese civilization, the clothing system functioned to form a social hierarchy, to regulate people’s activities, to harmonize the relations among the people, and finally to make a stable society under the close control of the state. The state control in the Ming remained effective until the reigns of Hongzhi (1488–1506) and Zhengde (1506–1521), when commercialization released people’s consumption desires and economic dynamics and caused deregulation of the Ming clothing system, which eventually undermined the state authority.     

Beveridge’s rival: Juliet Rhys-Williams and the campaign for basic income, 1942–55

Historians of Britain’s post-war welfare state have long been aware of the shortcomings of the social insurance model, but the political impact of the Beveridge report has tended to obscure the alternative visions of welfare canvassed in the 1940s and 1950s. This article examines the social activist Juliet Rhys-Williams’ campaign for the integration of the tax and benefit systems and the provision of a universal basic income, which attracted wide interest from economists, journalists, and Liberal and Conservative politicians during and after the Second World War. Though Rhys-Williams’ proposals were not adopted, they helped establish a distinctive ‘social market’ perspective on welfare provision which has become central to British social policy debates since the 1960s and 1970s.     

One Model Does Not Fit All: The Varied Politics of State Immigrant Policies, 2005–16

This article addresses conceptual and measurement challenges that complicate the study of state immigrant policies. First, given the multiple facets of immigrant‐related policy, policy‐specific effects may be obscured by highly aggregated outcomes variables. Second, variables of interest often capture both time‐varying and time‐invariant effects, potentially producing coefficients that are uninterpretable averages of both processes. This article presents a research design that addresses both of these obstacles and applies it to an original dataset of both integrative and punitive policies adopted over the period 2005–16. The findings suggest that the causal roles of growing immigrant populations, partisanship, and wealth vary across different clusters of immigrant policies and that average, cross‐state effects often differ from within‐state effects. Future research would do well to clearly link theoretical expectations to specific types of policy outcomes and test hypotheses over both integrative and restrictive outcomes.     

Measuring Complex State Policies: Pitfalls and Considerations,with an Application to Race and Welfare Policy

Welfare policy is multidimensional because of the political compromises, competing goals, and federalist structure underpinning it. This complexity has hindered measurement and, therefore, the comparability of research on race and welfare policy. This paper describes a measurement strategy that is transparent, replicable, and attuned to matching the assumptions of statistical models to the policy process. We demonstrate that this strategy leads to more nuanced conclusions regarding the relationship between minority caseloads and the flexibility of state welfare policies. The strategy and recommendations are adaptable to research agendas that scholars bring to the comparative study of welfare in the U.S. states, countries, or other units—and to other complex policies enacted in federal systems.     

Weathering the Storm: Social Policy and the Great Recession

This review discusses recent challenges to the welfare state arising from the Great Recession (GR). The GR was a significant event for social policy analysts, as it tested the responsiveness of welfare systems in the midst of a recent trend toward austerity politics in advanced economies. Social policy changes were part of the toolkit advanced democracies used to respond to the GR, and the welfare state mitigated the consequences of the GR. However, a stark limitation of the social safety net in the United States was the failure to assist immigrant households. The nexus of immigration and social policy is likely to be a significant controversy as we consider the meaning of social citizenship.     

Studying Immigrant Policy One Law at a Time

This article shows that, in the study of immigrant integration policy in the U.S. states, it is critical to report data and coding decisions for individual laws. This analysis uses an updated and public database of law‐level decisions, which includes 2,703 legislative actions recorded by the National Conference of State Legislatures from 2005 to 2016. These data are used to estimate models of aggregate state policy activity in a variety of ways: as a single continuum of policy balance versus separate models of welcoming and hostile, lumping all policy subareas together versus analyzing a specific subarea, and lumping all years together in one cross section versus panel analysis. The results in these models differ enough to indicate that reporting codes for individual‐level laws is absolutely essential so that each researcher easily can construct the measure that fits his or her theoretical framework best.     

After Empire: Karl Renner's Danubian model of pluralism

This article argues that Karl Renner's multinational model for the Austrian‐Hungarian Empire is an alternative model for contemporary a‐territorial, multinational and federal arrangements. Nations, in his view, should act as intermediary bodies between the relevant communities and the state. His concept of ‘subjective public law’ combines principles that most authors find mutually exclusive: individual rights, choice over one's national cultural membership, non‐territorial administration of national communities and overseeing of equal collective rights by the state. Neither Staatsnation nor Kulturnation, the model is a combination of the two under the auspices of a federal state combined with a strong theory of individual and collective rights. I provide the reader with a comprehensive intellectual biography of Karl Renner, as I argue that an understanding of the man himself, his political pragmatism and his statism are crucial to comprehending this theoretical position. Throughout his life, Renner was a German nationalist, held a strong nostalgia for the Habsburg Empire and voted in favour of the Anschluß. His concurrent careers as a scholar and as a politician account for a series of contradictions. I argue however that these can be reconciled and explained by a careful comparative reading of his scholarly work and his political statements.
