Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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

Translators' Work Attitude
No full textThe study aims to adapt the job satisfaction, work-life balance, turnover intention, and workload scales developed for employees from different sectors to translators. The study conducted with the participation of 216 translators living and working in different provinces in Turkey shows that these adapted scales are valid and reliable measurement tools in the Turkish language (Chi-square/df: 1.71; RMSEA: 0.058; SRMR: 0.049; NFI: 0.96; NNFI: 0.98; CFI: 0.98, GFI: 0.90 and AGFI: 0.85)
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe 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
Response in vitro of lignin degrading fungi to single or combined applications of a biochar and a compost humic acid
No full textThe fungi Stereum hirsutum, Irpex lacteus, Phanerochaete chrysosporium, Bjerkandera adusta, Trametes versicolor and Pleurotus ostreatus were treated in vitro with a biochar (BC) from red spruce wood at doses of 0.2% (w/v, BCLD) and 1% (BCHD), the BC water extract (BCWE) at doses of 0.2% (w/v, BCWELD) and 1% (BCWEHD), a compost humic acid (HA) at a concentration of 200 mg L-1and combinations BCWE-HA. All BC treatments stimulated P. ostreatus growth (up to 26%). T. versicolor growth was increased (up to 10%) and reduced (down to 33%) by BCLDand BCHD, respectively. All the other fungi were always inhibited by BC (down to 59% for B. adusta with BCHD). BCWELDincreased hyphal elongation of B. adusta and T. versicolor up to 22% and 12%, respectively, whereas BCWEHDslightly reduced that of B. adusta. In general, both HA alone and all combinations BCWE-HA at both doses significantly stimulated mycelial growth of B. adusta, T. versicolor and P. ostreatus (up to 22% for B. adusta) or were irrelevant. These findings indicate that when BC is incorporated in soil, BC activity in vitro on ligninolytic fungi might be considerably modified by the contents of water and humic substances present in soil
Impact of type and dose of biochar and hydrochar on growth response of phytopathogenic and antagonistic soil-resident fungi
No full textBiochar (BC) and hydrochar (HC) are solid
by-products obtained through, respectively, pyrolysis
and hydrothermal carbonization of biomass.
Both materials are used as organic amendments
allowing carbon sequestration in soil. Two BCs,
from spruce pellets (BCSP) and grapevine pruning
residues (BCGV), and two HCs, from urban pruning
residues (HCUP) and the organic fraction of solid
urban waste (HCSU), were tested at concentrations
of 0.2 and 1% (w/v) on soil-resident fungi. The
higher dose of BC samples significantly reduced
mycelial growth of the phytopathogens Rhizoctonia
solani and Botrytis cinerea (up to 53% for BCGV on
B. cinerea after 24 h from inoculation, compared to
control), whereas, in general, the lower dose of both
BCs inhibited R. solani for the whole experiment
and B. cinerea only initially. HC samples evidenced
a general lower toxicity on the two pathogens than
BCs. In fact, only HCUP at both concentrations
reduced hyphal elongation of the sole B. cinerea for
the entire experimental time (up to of 38% for both
doses at 24 h from inoculation). All BC and HC
treatments at the lower concentration did not influence
or greatly stimulated the antagonists Trichoderma
harzianum and T. virens. Differently, the
higher dose of these materials caused some suppression
at the initial stage or at each sampling by
BCSP on T. harzianum and HCUP on T. virens. The
whole results obtained indicate a plant protective
activity of these materials with consequent less
need for fungicidal treatments
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

A Two-Step Approach to Eliminate Pesticides and Estrogens from a Wastewater and Reduce Its Phytotoxicity: Adsorption onto Plant-Derived Materials and Fungal Degradation
No full textIn this study, adsorption and biodegradation were exploited sequentially to remove the herbicide fenuron, the insecticide carbaryl and the estrogens 17β-estradiol (E2) and 4-tert-octylphenol (OP) from a municipal landfill leachate (MuLL). In the first step, we used spent coffee grounds, almond shells, a biochar and potato dextrose agar to adsorb the compounds spiked in MuLL at a concentration of 1 mg L−1. After only 3 days, any adsorbent removed from MuLL the totality of E2 and OP, averagely more than 95 % of carbaryl and 62 % of fenuron (81 % after 7 days). In the second step, the adsorbents collected from MuLL after 7 days were inoculated with the fungi Bjerkandera adusta and Irpex lacteus, separately. After 7 days, the maximum degradation occurred for OP in any treatment being averagely 78 and 74 % using B. adusta and I. lacteus, respectively. After 15 days, the average percentages of fenuron, carbaryl, E2 and OP degraded were, respectively, 75, 76, 88 and 88 % using B. adusta, and 74, 79, 85 and 89 % using I. lacteus. Residual estrogenicity in the adsorbents, tested with the recombinant yeast assay, was strictly related to residual E2, thus indicating a negligible contribution from the other contaminants and/or degradation products. The 7-day treatment of MuLL with the adsorbents caused a significant abatement of MuLL phytotoxicity on flax (2.5 times seedling elongation with coffee grounds, compared to MuLL) and a huge stimulation of rapeseed respect to water (biomass almost doubled), thus suggesting a possible worthwhile recycling of this wastewater in agriculture
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe 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
