Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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
Dispelling the Myths Behind First-author Citation Counts
No full textWe 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
Credit rationing or entrepreneurial risk aversion? An alternative explanation for the Evans and Jovanovic finding
No full textEvans and Jovanovic ('EJ') [Evans, D., Jovanovic, B., 1989. An estimated model of entrepreneurial choice under Liquidity constraints. Journal of Political Economy 97 (4), 808-827.] claimed that in a credit market with collateral-based lending, credit rationing occurs if more collateral increases startups. Adjusting the model to incorporate uncertainty and decreasing absolute risk aversion, this relationship can be explained as a risk averter's response to the lowered riskiness of self- over wage-employment.

No full textTuned polyurethanes for soft tissue regeneration
No full textThe applications of tissue engineering are increasing rapidly in biomedicine. Researcher Daniela Jovanovic developed new synthetic biomaterials for scaffolds that can be used for soft tissue regeneration, and possibly new tissue and organ formation, for example blood vessels or heart tissue. The focus of this research was on the development of biodegradable scaffolds. This is a crucial aspect for application, since recovery only occurs when physiological turnover and new tissue formation are balanced. Several commercially available biomaterials were modified with the aim to alter the biodegrading properties. The results are promising, because the new materials were incorporated well.

Pragmatic Case Studies as a Source of Unity in Applied Psychology
No full textTo unify or not to unify applied psychology: that is the question. In this article we review pendulum swings in the historical efforts to answer this question—from a comprehensive, positivist, “top-down,” deductive yes between the 1930s and the early 60s, to a postmodern no since then. A rationale and proposal for a limited, “bottom-up,” inductive yes in applied psychology is then presented, employing a case-based paradigm that integrates both positivist and postmodern themes and components. This paradigm is labeled “pragmatic psychology” and, its specific use of case studies, the “Pragmatic Case Study Method” (“PCS Method”). We call for the creation of peer-reviewed journal-databases of pragmatic case studies as a foundational source of unifying applied knowledge in our discipline. As one example, the potential of the PCS Method for unifying different angles of theoretical regard is illustrated in an area of applied psychology, psychotherapy, via the case of Mrs. B. The article then turns to the broader historical and epistemological arguments for the unifying nature of the PCS Method in both applied and basic psychology.Peer reviewe
