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

No full textComparing soil organic carbon stocks in contrasting Mediterranean pedosystems: How physical-chemical properties and land uses influence its behavior
No full textSoils play a pivotal role in the global carbon cycle processes and behavior, with soil organic carbon stocks (SOCs) representing the largest terrestrial carbon (C) pool. Soil C sequestration enhanced soil quality and the overall ecosystem goods and services, together with socio-economic benefits. The Mediterranean areas are one of the world’s biodiversity hotspots for conservation priorities. The Sardinia Island (south Italy) hosts peculiar eco- and pedosystems thanks to its peculiar climatic, geological, geomorphological, and ancient land use history featured for one of the oldest civilizations (Nuragic, 6,000 BC). All factors are brought together in extremely peculiar soil conditions. This study aimed to investigate SOCs and related behavior in two contrasting Mediterranean pedosystems in Sardinia (Cambisols developed on granite vs Luvisols on limestone), featuring different land covers, by comparing: i) surface vs deep soil horizons (A vs B); ii) different land covers inside and between the two investigated pedosystems. Several properties were assessed, including vegetation (vascular plants), litter (C, N, C/N, litter carbon stocks, P, Ca, Mg, Na, K, Cu, Fe, Mn, and Zn), and soil physical- (sand, silt, and clay contents, bulk density) chemical features (pH, electrical conductivity, soil organic matter, total N, total P, available P, C/N, exchangeable H+Al, exchangeable cations, cation-exchange capacity, base saturation, Cu, Fe, Mn, and Zn), wherever feasible. Statistical analyses were performed to determine: i) significant differences (p < 0.05) between and among investigated horizons and land uses; ii) bivariate correlation between investigated parameters (Pearson’s Correlation Matrix (CM)); variability and complex multiple relationships among investigated parameters through factor analysis (FA), while a principal component analysis (PCA) was conducted to identify the soil physical-chemical parameters having greater importance in terms of observed variability within (a) the investigated pedosystem, as well as (b) among the different land covers. Results revealed that areas with natural or close-to-natural features exhibited significantly higher SOCs amounts compared to more intense and human-influenced land covers. Furthermore, the differences in substrate and following soil formation processes between the two investigated pedosystems led to different SOCs behaviors, demonstrating a strong relation between SOCs and intrinsic soil features. This emphasizes the greater importance of soil nature in influencing SOCs, greater compared to that shown by land cover variations. Consequently, this study blatantly demonstrates that SOCs investigations, if not carried out through an in-depth soil investigation, may lead to inaccurate, or even wrong, outcomes and following considerations.Soils play a pivotal role in the global carbon cycle processes and behavior, with soil organic carbon stocks (SOCs) representing the largest terrestrial carbon (C) pool.

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

Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe 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
