Are There Options to Prevent Early Occurring Deaths in Acute Myocardial Infarction: Prospective Evaluation of All < 24 h In-Hospital Deaths, 2004-2006-The MONICA/KORA Augsburg Infarction Registry
Full text linkObjectives: To provide valid clinical data of early in-hospital deaths with presumed acute myocardial infarction (AMI) who are often not included in clinical trials or registries. Methods: From August 2004 to August 2006 all patients (age 25-84 years) dying within 24 h after hospitalization in a large tertiary care academic teaching hospital were screened regarding an underlying cardiovascular cause of death. Results: After validation, 79 out of 1,352 patients remained with a final diagnosis of AMI. Sixty-six percent of these experienced prehospital cardiac arrest or shock. In 37% no resuscitation attempts were performed in-hospital, the most common reason being multimorbidity. Only 23% could be transferred to coronary angiography for revascularisation attempts. An independent panel of clinicians judged that only in one patient would another management strategy have been promising. Of interest, 33% of the deceased patients had typical or atypical chest pain the days before the lethal event. Conclusion: A large percentage of AMI patients who died soon after hospitalization were in critical circulatory state directly before hospitalization. In 37%, in-hospital resuscitation attempts were omitted for understandable reasons. Options for improvement in acute care in the investigated setting were not found. However, in one third of the cases earlier preventive measures might have been reasonable. Copyright (C) 2010 S. Karger AG, Base
MeSH term explosion and author rank improve expert recommendations
Full text linkInformation overload is an often-cited phenomenon that reduces the productivity, efficiency and efficacy of scientists. One challenge for scientists is to find appropriate collaborators in their research. The literature describes various solutions to the problem of expertise location, but most current approaches do not appear to be very suitable for expert recommendations in biomedical research. In this study, we present the development and initial evaluation of a vector space model-based algorithm to calculate researcher similarity using four inputs: 1) MeSH terms of publications; 2) MeSH terms and author rank; 3) exploded MeSH terms; and 4) exploded MeSH terms and author rank. We developed and evaluated the algorithm using a data set of 17,525 authors and their 22,542 papers. On average, our algorithms correctly predicted 2.5 of the top 5/10 coauthors of individual scientists. Exploded MeSH and author rank outperformed all other algorithms in accuracy, followed closely by MeSH and author rank. Our results show that the accuracy of MeSH term-based matching can be enhanced with other metadata such as author rank
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

"Closing the R&D Gap, Evaluating the Sources of R&D Spending"
Full text linkBoth spending and tax policies have been implemented in the United States with the goal of stimulating private sector research and development (R&D). Karier questions whether current R&D policy, especially the research and experimentation tax credit, can contribute to closing the gap between nondefense expenditures on R&D in the United States and such expenditures in other countries, such as Japan and Germany. He also explores possible changes to our current R&D policy to make it more effective.
A Cross-Cultural Study of Weddings through Media and Ritual: Analyzing Indian and North American Weddings
Full text linkThe wedding is one of the only rituals or events that many cultures of the world consistently have in common. Weddings are found in almost every society. A wedding can feed consumer appetites and the industry that supports it. Costs for the average United States wedding can range from 35,530 or more (“Cost of Weddings” 2006). The costs of Indian wedding ceremonies vary from 2 million (Das 2005). Despite this large range the Indian wedding industry averages only 50 billion each year (“Cost of Weddings” 2006, Das 2005). Remarriages constitute 30% of the American wedding industry (Ingram 1999) while in India, remarriage is relatively uncommon. Given the amount of money spent on this cultural ritual, it is reasonable to assert that it carries a great deal of personal, cultural, and social significance. I’m going to contrast and compare Indian and American weddings through an examination of film. This study is similar to Best’s (2000) study of American proms, another related cultural tradition. Specifically I will examine portrayals of wedding ceremonies as presented by both Hollywood and Bollywood films
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods

The R&D Tax Incentives
No full textThis article sets out some background information and reflections of the author on the R&D tax incentive schemes included in the Common Corporate Tax Base (CCTB) Proposal. In particular the author analyzes the stimulus to private R&D through ad hoc tax incentives included in the CCTB Proposal and dives into the actual provisions included in the Proposal highlighting the most relevant issues connected with their design and interpretation. Moreover, the author explores the interaction between the CCTB Proposal and the granting by Member States of domestic R&D tax incentives
