Sustained Organizational Influence: American Legislative Exchange Council and the Diffusion of Anti‐Sanctuary Policy

Building upon existing literature, we offer a particular model of network policy diffusion—which we call sustained organizational influence. Sustained organizational influence necessitates an institutional focus across a broad range of issues and across a long period of time. Sustaining organizations are well‐financed, and exert their influence on legislators through benefits, shared ideological interests, and time‐saving opportunities. Sustaining organizations' centralized nature makes legislators' jobs easier by providing legislators with ready‐made model legislation. We argue that sustaining organizations uniquely contribute to policy diffusion in the U.S. states. We evaluate this model with a case study of state‐level immigration sanctuary policy making and the role that the American Legislative Exchange Council (ALEC) played in disseminating model legislation. Through quantitative text analysis and several negative binomial state‐level regression models, we demonstrate that ALEC has exerted an overwhelming influence on the introduction of anti‐sanctuary legislative proposals in the U.S. states over the past 7 years consistent with our particular model of network policy diffusion. Implications are discussed.

The nation and the city: urban festivals and cultural mobilisation

This article attempts to map the relations between nation‐building processes in 19th‐century Europe and city cultures with their urban sociability. Three patterns are surveyed: [1] the modern‐national assimilation of medieval and early‐modern city cultures (sample case: Orléans and the French cult of Joan of Arc); [2] the modular replication across cities of urban festivals as cultural mobilizers (sample case: the spread of Floral Games festivals in Southern France and Northern Spain); [3] the reticulation of city‐based practices into a nationwide and nation‐building network (sample cases: the role of choral societies in German cultural nationalism; and its transnational knock‐on effect in the Baltic Provinces). By choosing the city as our social focus and placing it (or rather, its ideal‐type ‘Urbania’) alongside Gellner's ideal‐types of ‘Megalomania’ and ‘Ruritania’, we can avoid the finalism of studying regionalist and nationalist movements in the analytical framework of the post‐Versailles state system, and we gain a better understanding of the granulated, localized social basis of such movements and the translocally homogenizing role of culture.     

The spatial diffusion of party entrepreneurs in Swedish local politics

Theoretical expectations predict instances of party formation to be unusual. It is therefore puzzling that new ‘non-national’ parties became increasingly common in Swedish local councils between 1973 and 2002. This article sets out to answer why party formation became an increasingly popular strategy throughout these years. I show that previous research has not provided satisfactory answers, and argue that existing theories are of limited use explaining this development. It is suggested that a diffusion mechanism may explain why new parties became increasingly common in Swedish local councils. Theoretically, it is argued that an entrepreneur who creates a new party inspires potential entrepreneurs in neighboring municipalities to repeat this at later points in time. A geographical clustering of municipalities where these parties exist is therefore expected. Support is found for this assertion. The result is important since it outperforms the alternative ‘local contextual’, socioeconomic hypotheses previously tested in this empirical setting.     

Rapid Na, Cu exchange between synthetic fluid inclusions and external aqueous solutions: evidence from LA-ICP-MS analysis

Three sets of equilibration experiments (Set 1 to Set 3) were performed in cold-seal pressure vessels to investigate the compositional modification of quartz-hosted fluid inclusions after entrapment. Each set of experiment consisted of two stages. In a pre-run, fluid inclusions containing 5–10 wt% NaCl and selected trace elements were synthesized at 700°C/140–200 MPa. These samples were then loaded into new capsules together with Cu-bearing solutions and some mineral buffers, and re-equilibrated at 600–800°C and 70–140 MPa for 6–8 days. LA-ICP-MS analysis of individual fluid inclusions reveals that in re-equilibration experiments in which the outer fluid was composed of KCl (±FeCl₂) up to 83% of the original Na content of pre-existing fluid inclusions were lost, and up to 5660 ppm Cu were gained. Other elements with larger ionic radii (i.e. K, Fe, Ba, Sr) were not exchanged, demonstrating that the inclusions remained physically intact and that Na and Cu were transported through quartz by diffusion. The observed Na loss from pre-existing fluid inclusions correlates positively with Cu gain, with about 1 Cu atom being gained per 10 Na atoms lost. Thus, Na and Cu (plus probably H) were exchanged by interdiffusion. Remarkably, this processes resulted in up to 10 times higher Cu concentrations in re-equilibrated inclusions than were present in the outer fluid, i.e. Cu diffused 'uphill'. Large variations of Cu concentrations relative to the concentration of other elements are common also in natural fluid inclusion assemblages. However, no evidence for a correlation between Cu content and Na content was found so far, suggesting that Cu diffusion in natural samples may be dominated by processes other than Na–Cu interdiffusion.     

基于文化地理学视角的秦腔文化起源与扩散

秦腔起源于古代陕甘一带民间歌舞,流行于陕、甘、青、宁、新等地。本文从文化地理学的角度,采用文化扩散和整合的思维着重分析了秦腔文化形成的自然地理与社会原因,系统探讨了不同时期和地区秦腔文化的扩散类型、传播路径与整合特征。结果认为,秦腔文化扩散的主要方式是人口迁移与艺人游走,特点是多级化。秦腔文化景观反映当地发展史,是多种地域文化要素相互作用的产物,传播时的屏障作用具有正负双重影响。未来秦腔文化的发展要根植于群众并植入现代元素,以实现秦腔文化新的繁荣。     

不同尺度下农业创新技术空间扩散的实证研究——以中国果业协会果业技术扩散为例

目前,国内外对技术扩散的研究中时间维角度扩散研究较多,而空间维扩散研究相对薄弱。以中国果业协会为依托,通过对协会内果树系列技术成果采用系统调查的基础上,运用相关分析和行为分析的方法,从不同尺度对技术空间扩散进行透视,得出以下结论:①不同尺度下影响农业技术扩散和使用的因素相差较大。宏观尺度下影响果树系列技术扩散的主要因子为规模,中微观尺度下影响技术扩散的主要因子为距离;②随着空间尺度的缩减,技术扩散由明显的规模等级扩散向随距离增加扩散强度减弱的渐进扩散转化;③农业技术在空间扩散方向上具有\"寻\"的特征,即技术扩散总是在追求扩散效益最大化;④微观尺度的农户行为分析表明,农户技术采用行为主要受农户本身对高收益的追求和外部因素对农户的影响两方面作用。     

Time to Say Goodbye

Tim Hortons’ first donut store was established in Hamilton, Ontario, in 1964; other stores were added over time as the chain gradually diffused across Canada to become the country’s largest quick-service restaurant chain with more than 2,400 restaurants. In achieving this dominant status it adopted one of the strategies of any successful restaurant chain; utilizing a uniform architectural style to emphasize to customers the consistency in its menu and operations. This article examines the processes underlying the development of the Tim Hortons brand and the diffusion of its restaurants into the US, specifically the appearance of their restaurants in the Great Lakes borderlands. The study found a consistent architectural style in Ontario but several different styles in Michigan and New York. It is suggested that this lack of consistency in brand identification in its US restaurants is a contributory factor to their lack of profitability and smaller sales.     

The Formation of Swedish Independent Local Lists, 1990–2015.

In this comparative case-study, elements of diffusion theory are used to examine local conditions conducive to political organization in terms of independent local lists (ILLs). Empirical evidence supports the formulation of three hypotheses for future and more systematic research into the problem: a hypothesis of size, an elite-hypothesis and a mobilization-hypothesis. Although several factors are likely to play a role, the results suggest particularly that ILLs are less likely to occur in localities lacking historical legacies in terms of popular mobilization.     

The spatial anatomy of an epidemic: influenza in London and the county boroughs of England and Wales, 1918–1919

From uncertain origins in the spring of 1918, an apparently new variant of influenza A virus spread around the world as three distinct diffusion waves, infecting half a billion and probably killing around 40 million people. This paper examines the spatial structure of influenza transmission during the ten–month course of the epidemic in England and Wales, June 1918–April 1919, using the weekly counts of influenza deaths in London and the county boroughs as collated by the General Register Office, London. In addition, a particular case study of the borough of Cambridge is presented. From mid–1916, Cambridge contained, as well as its undergraduate population, a large naval contingent billeted in both the colleges and the town. It therefore affords the opportunity of studying the effect of the epidemic in contiguous groups with widely differing demographic characteristics. Through the application of a range of statistical methods (average lags, correlations and regressions), it is shown that the three waves that comprised the pandemic had fundamentally different spatial and temporal characteristics. The first, moving through a population that was a virgin soil to the new virus strain, was explosive in its north to south progress across the country. The second wave was somewhat slower in its rate of diffusion and displayed a south to north drift. Finally, the third wave reverted more closely to the form of the first. The spread of all three waves, however, was underpinned by a clearly defined process of spatial contagion. The Cambridge study showed the special characteristics of this pandemic in terms of the ages of those attacked: high rates were experienced across the age spectrum, a feature also seen internationally.
