Spirituality and Prayer on Teacher Stress and Burnout in an Italian Cohort: A Pilot, Before-After Controlled Study
Full text linkIntroduction: Teaching is a stressful profession that exposes workers to the risk
of burnout. Techniques involving higher mental functions, such as transcendental
meditation and prayer, have been used in stress and burnout prevention programs.
In this study, we report the results of an experience conducted in a group of teachers of
a religious institute, in which prayer was used as a technique to prevent burnout.
Methods: Fifty teachers and support staff employed at a Catholic school of a
Congregation of nuns volunteered for this study. They were randomized into two
groups: prayer treatment (n = 25) or control group (n = 25). The treatment protocol
was based on the combination of individual Christian prayer and a focus group
of prayer-reflection. The participants received two 30 min training sessions a week
over 2 months. Job satisfaction, well-being, and burnout symptoms (emotional
exhaustion and depersonalization sub-scales) were measured at baseline and at followup (4 months) with the Italian versions of the Maslach Burnout Inventory validated for
teaching and education sector, the General Health Questionnaire, and the Warr, Cook,
and Wall’s Job Satisfaction Scale.
Results: At follow-up, a significant improvement of all outcome measures was
observed. Emotional exhaustion (16.80–4.92, p < 0.001), depersonalization (3.72–
0.60, p < 0.001) levels, and psychological impairment (10.08–2.04, p < 0.001) were
significantly decreased, and job satisfaction (45.96–77.00, p < 0.001) was increased.
The effect sizes (Glass’ 1) of the therapeutic interventions ranged from 0.53 (satisfaction
level) to 2.87 (psychological health), suggesting moderate to large effects.
Discussion: Prayer could be effective, no less than meditation and other spiritual or
mind-body techniques, in contrasting the negative effects of occupational stress and
preventing burnout among teachers and possibly other human service professionals
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
Light-Induced Paramagnetism in Colloidal Ag<sup>+</Sup>-doped Cdse Nanoplatelets

In this work, we used magnetic circularly polarized luminescence and magnetic circular dichroism spectroscopy to study light-induced magnetism for the first time in 2D solution-processed structures doped with nominally nonmagnetic Ag+ impurities. The excitonic circular polarization (P-X) and the exciton Zeeman splitting (Delta E-Z) were recorded as a function of the magnetic field (B) and temperature (T). Both Delta E-Z and P-X have a Brillouin-function-like dependence on B and T, verifying the presence of paramagnetism in Ag+-doped CdSe NPLs. The observed light-induced magnetism is attributed to the transformation of nonmagnetic Ag+ ions into Ag2+, which have a nonzero magnetic moment. This work points to the possibility of incorporating these nanoplatelets into spintronic devices, in which light can be used to control the spin injection.NSF MRI Award [1726303]; Singapore National Research Foundation [NRF-NRFI2016-08, NRF-CRP14-2014-03]; Science and Engineering Research Council, Agency for Science, Technology, and Research (A*STAR) of Singapore; TUBA; European Union's Horizon 2020 research and innovation program under the Marie Sklodowska-Curie grant [798697]; Scientific Center for Optical and Electron Microscopy (ScopeM) of the Swiss Federal Institute of Technology ETHZ; Division Of Materials Research; Direct For Mathematical & Physical Scien [1726303] Funding Source: National Science Foundation; Marie Curie Actions (MSCA) [798697] Funding Source: Marie Curie Actions (MSCA)A.P. acknowledges support from the NSF MRI Award 1726303.

Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe 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
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
