Within the perimeter of patent collaboration networks, the average distance of collaborations and the number of countries involved per each collaboration have been shown to have increased steadily in time. Less attention, though, has been devoted to assessing whether this growth of cross-country collaborations is stable in time. To address this scientific question we focus on the identification of long-term correlations (i.e. temporal persistence). Our data set consists of time series of yearly average collaboration radii and of cross-border links in the Euro-American subsystem of the global collaboration network for the period 1978–2014. To investigate the fundamental persistence properties of these time series, we use Detrended Fluctuation Analysis, a method that allows us to measure long-term correlations in detrended signals. Also, we devise a general and original procedure to assess the statistical significance of results for short time series. Our results, showing that long-term correlations do exist in the majority of our signals, reinforce the hypothesis of a diminishing role of geographical distance in technological collaborations. Results at national level show that a significant degree of heterogeneity in persistence parameters can be detected within Europe, irrespectively of the efforts towards the set-up of an integrated European Research Area.  相似文献

In this work we address the comprehensive Scimago Institutions Ranking 2012, proposing a data visualization of the listed bibliometric indicators for the 509 Higher Education Institutions among the 600 largest research institutions ranked according to their outputs. We focus on research impact, internationalization and leadership indicators, which became important benchmarks in a worldwide discussion about research quality and impact policies for universities. Our data visualization reveals a qualitative difference between the behavior of Northern American and Western European Higher Education Institutions concerning International collaboration levels. Chinese universities show still a systematic low international collaboration levels which are positively linked to the low research impact. The data suggests that research impact can be related directly to internationalization only to rather low values for both indicators. Above world average, other determinants may become relevant in fostering further impact. The leadership indicator provides further insights to the collaborative environment of universities in different geographical regions, as well as the optimized collaboration portfolio for enhancing research impact.  相似文献

Greater collaboration generally produces higher category normalised citation impact (CNCI) and more influential science. Citation differences between domestic and international collaborative articles are known, but obscured in analyses of countries’ CNCIs, compromising evaluation insights. Here, we address this problem by deconstructing and distinguishing domestic and international collaboration types to explore differences in article citation rates between collaboration type and countries. Using Web of Science article data covering 2009–2018, we find that individual country citation and CNCI profiles vary significantly between collaboration types (e.g., domestic single institution and international bilateral) and credit counting methods (full and fractional). The ‘boosting’ effect of international collaboration is greatest where total research capacity is smallest, which could mislead interpretation of performance for policy and management purposes. By incorporating collaboration type into the CNCI calculation, we define a new metric labelled Collab-CNCI. This can account for collaboration effects without presuming credit (as fractional counting does). We recommend that analysts should: (1) partition all article datasets so that citation counts can be normalised by collaboration type (Collab-CNCI) to enable improved interpretation for research policy and management; and (2) consider filtering out smaller entities from multinational and multi-institutional analyses where their inclusion is likely to obscure interpretation.  相似文献

Increasingly, scholars have been conducting team-based research with multinational collaborators to carry out internationally relevant studies, generate global impact, and promote academic exchanges. In this paper, we examine how four types of distance, i.e., geographic, political, cultural, and economic, relate to the output of international research collaborations. We analyze a bibliometric data set derived from four leading marketing journals spanning the 2001–2016 time frame. Among other insights, our results show that in the context of international collaborative research efforts, co-authors from countries with wider economic distances and narrower political distances have published fewer articles and received fewer citations compared to those from countries with narrower economic distances and wider political distances.  相似文献

Large-scale information technology implementations are risky projects, and the challenges and risks multiply when multiple organizations are involved, as is often the case in e-government initiatives. Some of the risk can be addressed by carefully aligning the partners' motivations, which are affected by each organization's internal and external operational and information technology strategies. In this paper, we propose a strategic alignment framework and use it to examine the motivations of a set of collaborating government agencies and businesses in the pilot implementation of the Internet Payment Platform, an interorganizational, third-party hosted, e-procurement system. As we predict, the partners in this study had varied technical, political, economic, and operational motivations for participating in the project. Even so, the participating agencies reported positive outcomes from the project, and look forward to further collaboration on the next iteration of this e-procurement system.  相似文献

In describing the Renaissance-style publisher of the 1990s, this article emphasizes the craft and skills needed to maintain quality. Ian Montagnes suggests that these skills must now be taught formally, rather than by apprenticeship. He also describes one such training program that he has conducted for editors in developing countries. Ian Montagnes is assistant director and editor-in-chief of the University of Toronto Press. He has served continuously as either associated editor or editor ofScholarly Publishing: A Journal for Authors and Editors since its inception in 1969. He has also been active in the Canadian and American associations of university presses and the Society for Scholarly Publishing  相似文献

The percentages of shares of world publications of the European Union and its member states, China, and the United States have been represented differently as a result of using different databases. An analytical variant of the Web-of-Science (of Thomson Reuters) enables us to study the dynamics in the world publication system in terms of the field-normalized top-1% and top-10% most-frequently cited publications. Comparing the EU28, USA, and China at the global level shows a top-level dynamic that is different from the analysis in terms of shares of publications: the United States remains far more productive in the top-1% of all papers; China drops out of the competition for elite status; and the EU28 increased its share among the top-cited papers from 2000 to 2010. Some of the EU28 member states overtook the United States during this decade; but a clear divide remains between EU15 (Western Europe) and the Accession Countries. Network analysis shows that China was embedded in this top-layer of internationally co-authored publications. These publications often involve more than a single European nation.  相似文献

The purpose of this column is to highlight information literacy activities that are occurring in organizations and institutions outside of libraries. Academic libraries have done much to advance information literacy in postsecondary institutions. Yet, much activity is also occurring outside of academic libraries in relation to information literacy. This column will feature some of those organizations and activities so that academic librarians may share information with them and develop new partnerships that will further advance the goals of information literacy.  相似文献

Scholars have devoted considerable attention to the concept of national identity. In a globalizing world, however, identity is increasingly shaped not only by one's own nation but also by foreign nations. With this in mind, this study theorizes international identity as a communicative process. We propose four features of international identity—that it is distinct, relational, contextual, and stratified—and examine these features in one crucial context: the modern American presidency. Our content analysis of every mention of a foreign entity in 74 years worth of presidential discourse—2480 mentions in all—supports our conception of international identity and begins to identify the parameters of this construct in American political communication.  相似文献

Much of information policy is focused on establishing the parameters of information access—ensuring or limiting access to certain types of information. Given how central information access is to virtually every aspect of society, policy can be seen as one of the most significant forces influencing the information society. Recent events, however, have fueled changes in the ways that some governments use policy to shape access, none more significantly than the United States. This paper examines the meanings of and relationships between policy and access, as well as their key roles in society and democratic participation. Following an examination of the historical and social impacts of policies about access, the article analyzes the perspectives of the Bush administration on how policy should shape information access as an illustration of the relationships between policy and access. The paper examines the issues raised by the Bush administration’s views on access and policy and the implications of their policies for the United States, for the global information society, and for research related to information. Ultimately, the paper raises questions about the extent to which information policies about access can be used for overtly political purposes, what might be described as “information politics,” without significantly altering the meaning of information access in a society.  相似文献

Nations can be distinguished in terms of whether domestic or international research is cited. We analyzed the research output in the natural sciences of three leading European research economies (Germany, the Netherlands, and the UK) and ask where their researchers look for the knowledge that underpins their most highly-cited papers. Is one internationally oriented or is citation limited to national resources? Do the citation patterns reflect a growing differentiation between the domestic and international research enterprise? To evaluate change over time, we include natural-sciences papers published in the countries from three publication years: 2004, 2009, and 2014. The results show that articles co-authored by researchers from Germany or the Netherlands are less likely to be among the globally most highly-cited articles if they also cite “domestic” research (i.e. research authored by authors from the same country). To put this another way, less well-cited research is more likely to stand on domestic shoulders and research that becomes more highly-cited is more likely to stand on international shoulders. A possible reason for the results is that researchers “over-cite” the papers from their own country – lacking the focus on quality in citing. However, these differences between domestic and international shoulders are not visible for the UK.  相似文献

ABSTRACT

Exploring new sources on the Great War a hundred years after it ended is a unique and exciting experience for any First World War historian. The very nature of the documents that we are dealing with in the present case makes it even more thrilling: hundreds of investigation and prosecution files documenting the invasion and occupation of Belgium, produced by both military and civil jurisdictions in an effort to prosecute war criminals. These fascinating records – repatriated to Belgium from Moscow in 2002 – offer new material on issues such as the German atrocities and everyday life under the occupation, but they also provide highly valuable insights into the history of international criminal law. This exploratory article will trace the unexpected trajectory of these archives, contextualise their creation and highlight some of the treasures they contain. In doing so, this article will attempt to discuss the thorny issue of archive repatriation and the questions this raises from an archival and historical perspective. It also seeks to show that the establishment of an International Criminal Court, despite the fact that it is now being called into question more than ever before, rests on solid and far-reaching historical foundations.  相似文献

There are many community libraries in Ghana. Most of these libraries are established by non-governmental agencies, district assemblies, affluent or well-to-do individuals, and individuals with higher educational credentials hailing from these rural areas as memorial. There are many benefits that can be derived from the establishment of these libraries. Notwithstanding the numerous potential benefits of community libraries, many of these community libraries in Ghana have collapsed. The ones which are operating are fighting a battle of survival, struggling with numerous challenges. This article shines more light on the problems and challenges facing community libraries in Ghana and makes recommendations based on review of literature on the various challenges facing rural or community libraries elsewhere, and their proposed solutions.  相似文献

The archival sliver: Power, memory, and archives in South Africa   总被引:3,自引:3,他引:0  
Far from being a simple reflection of reality, archives are constructed windows into personal and collective processes. They at once express and are instruments of prevailing relations of power. Verne Harris makes these arguments through an account of archives and archivists in the context of South Africa's transition from apartheid to democracy. The account is deliberately shaped around three themes — race, power, and public records. While he concedes that the constructedness of memory and the dimension of power are most obvious in the extreme circumstances of oppression and rapid transition to democracy, he argues that these are realities informing archives in all circumstances. He makes an appeal to archivists to enchant their work by engaging these realities and by turning always towards the call of and for justice. This essay draws heavily on four articles published previously by me: “Towards a Culture of Transparency: Public Rights of Access to Official Records in South Africa”,American Archivist 57.4 (1994); “Redefining Archives in South Africa: Public Archives and Society in Transition, 1990–1996”,Archivaria 42 (1996); “Transforming Discourse and Legislation: A Perspective on South Africa's New National Archives Act”,ACARM Newsletter 18 (1996); and “Claiming Less, Delivering More: A Critique of Positivist Formulations on Archives in South Africa”,Archivaria 44 (1997). I am grateful to Ethel Kriger (National Archives of South Africa) and Tim Nuttall (University of Natal) for offering sometimes tough comment on an early draft of the essay. I remain, of course, fully responsible for the final text. I presented a version of it in the “Refiguring the Archive” seminar series, University of the Witwatersrand, Johannesburg, October 1998. That version was published in revised form in Carolyn Hamilton et al.,Refiguring the Archive (Cape Town: David Philip, 2002).  相似文献

The 1976 film Rocky is not the catalyst for conservative backlash that scholars of American cinema and culture have long made it out to be. Through detailed analysis this essay reveals two counterposed dramas: an epic race rivalry conceived by Creed, and a low mimetic comedy that sees Balboa integrated in his local community. The epic dissolves in carnivalesque play and gives way to the earnest local drama of building relationships. Rocky embodies some progressive ideals for race and class under the general theme of respect; it also manifests the men’s liberation movement against the classical male machine. As a pivotal film for critical conceptions of US cinema and culture after 1975, my reappraisal of Rocky challenges ideological criticism’s prevailing paradigm.  相似文献

1972年美国图书馆史学家迈克尔·哈里斯发表《历史视角下的美国公共图书馆目标:一种修正式解读》,从社会阶层论视角爬梳美国公共图书馆的起源及其领袖人物的图书馆目标,认为公共图书馆是社会精英阶层用以管理和控制社会的工具,批评传统进步主义图书馆史学家对相关问题的理想化认识。以菲莉丝·戴恩为代表的进步主义图书馆史学家认为公共图书馆是民主和人道主义的产物。戴恩批评哈里斯的修正式观点因缺乏扎实论据而失于偏颇。双方展开了1970年代美国图书馆史研究中的“哈里斯-戴恩论战”,引发学界对公共图书馆的起源和目标的深刻反思,对图书馆史研究的方法论和发展产生了深远影响。  相似文献

Alien Resurrection (1997) heightens the movements across dark humor and horror, and enables more pronounced and complex conjunctions across the three types of shadows put forward by Rushing/Frentz and Picart, particularly in the case of the monstrous female characters like Ripley and Call. These characters bisociate the realms of first shadow (female bodies), second shadow (products of technology), and third shadow (fearsome female freedom fighters). Nevertheless, both live—a rarity among Frankensteinian cinemyths. Alien Resurrection enables us to glimpse, through a glass darkly, other ways in which the gendered and raced complexities of the Frankenstein cinematic myth may be traced.  相似文献
