    Going Beyond Counting First Authors in Author Co-citation Analysis

    No full text
    The 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 text
    We 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

    Probabilistic models for the verification of human-computer interaction

    No full text
    In this paper, we present a method for the formalization of probabilistic models of human-computer interaction (HCI) including user behavior. These models can then be used for the analysis and verification of HCI systems with the support of model checking tools. This method allows to answer probabilistic questions like "what is the probability that the user will unintentionally send confidential information to unauthorized recipients." And it allows to compute average interaction costs and answer questions like "how much time does a user on average need to send an email?" © 2009 Springer Berlin Heidelberg.Bernhard Beckert and Markus Wagne

    Where do prices come from? Sociological approaches to price formation

    No full text
    The article provides an overview of the state of the art of sociological research on price formation. The dominant trait of the sociological approach to prices is to understand price formation not as the outcome of individual preferences but as the result of the social and political forces operating within the market field. The article proceeds from the concept of market fields and is organized around the three dominant approaches in economic sociology: the network approach, the institutional approach, and the cultural approach. -- Der Artikel gibt einen Überblick über den Forschungsstand zum Thema Preisbildung in der Soziologie. Ausgangspunkt der Betrachtung von Preisen aus soziologischer Perspektive ist, diese nicht als das Resultat individueller Präferenzen zu verstehen, sondern als Ausdruck der sozialen und politischen Kräfte in Märkten. Der Artikel orientiert sich an dem Konzept der Marktfelder und ist anhand der drei Hauptrichtungen der Wirtschaftssoziologie strukturiert: des Netzwerkansatzes, des institutionellen Ansatzes und des kulturellen Ansatzes.

    Role of Women in Promoting Sustainable Resource Management of Upland Bromo - East Java, Indonesia

    No full text
    Following the concept of political ecology, this chapter will explain the essential role women play in stabilizing resources regardless of the limited role they usually play in decision-making processes both in the household and the public sphere. Three villages in the highland areas around the Bromo Tengger Semeru National Park (BTSNP) were selected for case studies. Based on qualitative research (150 semi-structured interviews, 30 in-depth interviews with key informants and five focus group discussions), we found that women have a pivotal role in stabilizing land productivity, rationalizing energy consumption, promoting food security, and taking over men’s duties as men tend to enter the rural labor market. Unfortunately, such phenomenon was not followed by changes in the structure of decision-making processes

    Pragmatic Case Studies as a Source of Unity in Applied Psychology

    No full text
    To 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

    Appropriate Similarity Measures for Author Cocitation Analysis

    No full text
    We provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis

    Control code obfuscation by abstract interpretation

    No full text
    Control code obfuscation is intended to prevent malicious reverse engineering of software by masking the program control flow. These obfuscating transformations often rely on the existence of opaque predicates, that support the design of transformations that break up the program control flow. We prove that an algorithm for control obfuscation by opaque predicate insertion can be systematically derived as an abstraction of a suitable semantic transformation. In this framework, deobfuscation is interpreted as an attacker which can observe the computational behaviour of programs up to a given precision degree. Both obfuscation and deobfuscation can therefore be interpreted as approximations of program semantics, where approximation is formalized using abstract interpretation theory. In particular we prove that abstract interpretation provides here the adequate setting to measure the potency of an obfuscation algorithm by comparing the degree of abstraction of the most abstract domains which are able to disclose opaque predicates
