This article investigates how presidential policy attention is allocated across policy tools and whether there is a channeling of tool use by policy area. I also examine whether there is evidence of disproportionate information processing within presidential policy attention allocation and whether it is common across presidential policy tools. Presidential messages, hearings on administrations' legislative proposals, amicus briefs, and executive orders are employed to capture presidential policy tools. The allocation of attention via these four instruments is examined from 1957–2007 in the policy areas of defense and foreign affairs, macroeconomics, banking and commerce, civil rights, law and crime, and labor and immigration. I find that there is a canalization of presidential policy attention by instrument, and that the opportunity structure of policy tools shapes attention allocation. Additionally, I find evidence for punctuated equilibrium theory in the allocation of presidential policy attention via these four tools. When presidents do shift their attention to an issue area, they often attack the issue with some coordination of their policy instruments.  相似文献

整体的“世界史”概念是在地区国别史研究的基础上逐步形成的,对“世界体系”认知的热情从来也没有像第二次世界大战以后这样高涨。这种学术现象的出现是以经济发展全球化、生活模式单一化、价值观念趋同的趋势为大背景的。可以认为,真正意义的世界史观念是全球经济一体化不断深化和不同文化交流日益频繁这一形势在历史研究领域引起的反应。作为全球化的逆向思维,强调对话反对对抗,强调联系和交流反对封锁,对各个民族原创文明的探讨成为文化知识界的共识。对多元文明,特别是不同文明之间“联系”的探讨是整体世界史研究发展的又一种深层动力。整体的宏观的世界史研究与地区国别史研究相辅相成、互相促进。现代科技水平和新科技观念迅猛发展,促进了地区国别史、专门史、断代史学者的交流,加强了世界各地学者之间的联系,打破了历史学和其他哲学社会科学学科、甚至自然科学学科之间的壁垒,交叉与对比研究为世界史研究的新发展开辟出无限广阔的空间。  相似文献

European border externalization to “sending states” throughout Africa is a well-documented phenomenon. Less clear, however, is the role that African governments and implementing organizations play in border externalization, nor the precise mechanisms by which European borders are “mobilized” (Szary & Giraut, 2015) and projected into everyday spaces in “sending states”. Drawing on a case study of three different European border enforcement projects in The Gambia, I argue that a collaboration between the International Organization for Migration, the EU Emergency Trust Fund for Africa, and the Gambian government makes Gambians themselves agents of the European border. Drawing upon Szary and Giraut's notion of “borderities” (2015), I illustrate how the border is projected into The Gambia through an articulation of humanitarian borderwork with developmental approaches intended to solve the “root causes of migration” (Zaun & Nantermoz, 2021). Furthermore, I argue that the Gambian government is not passive in the process of border externalization, but actively involved in interpreting and rearticulating European policies and narratives about migration. Following Adamson and Tsourapas' (2020) reworking of the “migration state” concept, I demonstrate the Gambian government's active interests in bordering its own citizens: simultaneously encouraging emigration for the sake of national “development” while immobilizing young Gambians as part of a broader strategy to cooperate with European states. This research illustrates both the immense value of a “borderities” approach to studying contemporary migration management, and the close association between borderwork and nationhood in African post-colonial states.  相似文献

Site selection processes whereby companies choose a location for an expansion or relocation have changed substantially over the past several decades. One key shift has been the emergence of collaboration among both individual economic developers and cooperation among the communities they represent. The rise in collaborative practices has also been increasingly reflected in the contemporary economic development literature outside the discipline of geography. The aim of this paper is to provide an overview of economic development studies of collaboration and then to suggest ways that geographers might use concepts from that scholarship to inform and extend the limited number of studies exploring site selection practices. The paper begins by offering a context for the emergence of collaboration trends by highlighting the ways that information asymmetry in site selection processes create a demand for greater collaboration among industry practitioners. It then turns to an overview of the burgeoning literature on collaboration that has evolved over the last decade in the interdisciplinary scholarship on economic development. Next, the paper shifts to a discussion of the ways that geographers might use the literature on collaboration to inform studies of site selection, specifically focusing on geographic scale and research on site selection consultants as possible areas for future investigation. The article concludes by arguing that studying collaboration in the context of geographies of site selection holds the potential for greater insights into the broader outcomes of economic development.  相似文献

论广告的起源问题   总被引:1,自引:0,他引:1  
杨海军 《史学月刊》2000,(4):43-47,55
传统观点认为,广告是伴随着商品生产和商品交换而出现的,是商品经济发展的必然产物。这种观点所揭示的只是“商品广告”的起源问题。从广告的发展、演变历史及人们对广告的理解来看,无论是原始意义,还是现代意义上的广告,均并非单指“商品广告”。它还应包括政治、军事、文化广告,统称为“社会广告”。其产生的时间早于“商品广告”。本文的主要观点是:广告是人类有目的信息交流和传播活动的产物。  相似文献

In this paper, we survey the expanding body of literature on the Belt and Road Initiative (BRI) in Chinese and Anglophone geography, and locate the main lines of development. The emerging scholarship approaches the BRI as a spatial discourse and examines the production of geographical reasoning in statecraft. It also links up with studies of the BRI as both a material project and an everyday experience. We argue that it is in this combined understanding of BRI's multiple registers, as discourse, project, and experience, that a trilectical approach for future geographical engagement can be identified as the BRI edges to its second decade.  相似文献

This paper addresses the interaction between information technology (IT) and agglomeration. The literature distinguishes two types of interactions, namely a substitution effect and a complementarity effect. We conceptualise a third effect, namely a ‘spillover’ mechanism, by which IT allows places in close proximity of large cities to ‘borrow size’ and sustain greater product variety. We test these mechanisms using detailed data on restaurant cuisine variety in the Netherlands, and the IT dimension is measured through the use and penetration of online restaurant reviews. We find that IT complements cuisine variety in cities, and induces spillovers to smaller places near larger ones, allowing smaller places to sustain ‘rare’ cuisines that were traditionally only present in larger cities. As such, IT leads to the spread of agglomeration benefits such as local product variety over larger territories.  相似文献
