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

Abstract
PURPOSE: To evaluate the role of topical mitomycin C in corneal wound healing (CWH) after photorefractive keratectomy (PRK) in highly myopic eyes.
DESIGN: Prospective, double-masked, randomized clinical trial.
PARTICIPANTS: Seventy-two eyes of 36 patients affected by high (>7 diopters) myopia.
METHODS: In each patient, one eye was randomly assigned to PRK with intraoperative topical 0.02% mitomycin C application, and the fellow eye was treated with a placebo. Postoperatively, mitomycin C-treated eyes received artificial tears (3 times daily, tapered in 3 months), whereas the fellow eye was treated with fluorometholone sodium 2% and artificial tears (3 times daily, tapered in 3 months).
MAIN OUTCOME MEASURES: Uncorrected visual acuity (UCVA) and best-corrected visual acuity (BCVA), contrast sensitivity, manifest refraction, and biomicroscopy. Contrast sensitivity was determined using the Pelli-Robson chart. Corneal confocal microscopy documented CWH.
RESULTS: Mean follow-up was 18 months (range, 12-36). No side effects or toxic effects were documented. At 12-month follow-up examination, UCVAs (logarithm of the minimum angle of resolution) were 0.4+/-0.48 and 0.5+/-0.53 (P = .03) in mitomycin C-treated eyes and corticosteroid-treated eyes, respectively. At 1 year, corneal haze developed in 20% of corticosteroid-treated eyes, versus 0% of mitomycin C-treated eyes. At 12, 24, and 36 months, corneal confocal microscopy showed activated keratocytes and extracellular matrix significantly more evident in untreated eyes (Ps = 0.004, 0.024, and 0.046, respectively).
CONCLUSION: Topical intraoperative application of 0.02% mitomycin C can reduce haze formation in highly myopic eyes undergoing PRK.

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
Healthcare Regulation and Resilience - a Norwegian Multilevel Case Study
No full textIntroduction: A new regulatory framework (the Quality Improvement Regulation) to support local, management-based quality and safety efforts in hospitals was introduced to the Norwegian healthcare system in 2017. This thesis explores healthcare regulation and resilience through the Quality Improvement Regulation, by investigating its possible links to adaptive capacity in hospital management of quality and safety enhancing activities. The literature lacks studies exploring how regulation and resilience intertwine, two concepts often considered as counterparts. Hence, there is a gap in knowledge about regulatory and supervisory impact on quality and safety, and attention to hospital managers’ competences and responsibilities as key elements to resilience in healthcare. This thesis therefore casts a new light on how regulators and inspectors may design, inspect, and enforce a regulation regime, and thereby contribute to adaptive capacity, anticipatory capacity, and learning as key elements in different hospital contexts. Overall outputs from this thesis are important to the development and implementation of future regulatory amendments.
Aim: The overall aim of this thesis was to explore the rationale, expectations, implementation, and management of the Quality Improvement Regulation. The overall and leading research question was: How does a new healthcare regulation implemented across three system levels contribute to adaptive capacity in hospital management of quality and safety?
Methods: The study was designed as a multilevel, single embedded case study. Data was collected by approximately 500 pages of documentary evidence, 29 individual interviews and 3 focus group interviews (10 participants): in total 39 participants. Data was analyzed by legal dogmatic and qualitative content analysis. Three levels of stakeholders were included from the Norwegian healthcare system: macro-level (three governmental regulatory bodies), mesolevel (three County Governors), micro-level (three hospitals retrieved from two regional health authorities). Macro-level participants were seven strategic participants positioned at the Norwegian Ministry of Health and Care Services, the Norwegian Directorate of Health, and the Norwegian Board of Health Supervision. Meso-level participants were two chief county medical officers, three assistant chief county medical officers, and seven inspectors, recruited from three County Governors. Micro-level participants were 20 hospital managers or quality advisors selected from different levels at three hospitals.
Findings: Paper I (macro-level) explored the governmental rationale for developing the Quality Improvement Regulation, expectations towards hospital management and its expected influence on resilience. Data retrieved from documentary evidence and individual interviews indicated that the rationale for
the Quality Improvement Regulation’s design was to make it flexible to various hospital contexts. In turn, the macro-level expected hospital managers to anticipate local risks. However, the study found that the Government expected the generic regulatory design to come across as challenging for hospital managers and clinicians. Paper II (meso-level) investigated into changes in the supervisory approach and inspectors’ work to promote or hamper adaptive capacity and learning in hospitals. Evidence emerged from documents and focus group interviews and indicated that despite supervision being adapted to specific hospital contexts and the inspectors’ trade-offs, there was a general concern about the lack of impact of supervision on hospital performance. Paper III (micro-level) explored hospital managers’ perspectives on implementation efforts and the following work practices, to understand if, and how, the new Quality Improvement Regulation influenced quality and safety improvement activities. Across interview data, participants experienced the Quality Improvement Regulation as more suitable to variation and different contexts compared to the previous regulatory framework. However, findings revealed no change in practice related to quality and safety activities, solely due to the new regulatory framework, despite recent structural and cultural changes to quality improvement systems in hospitals. Data reported that lack of time, competence and/or motivation affected hospital implementation.
Conclusions: This thesis represents a rare glimpse into regulatory implementation efforts across three system levels, set out in a resilience in healthcare perspective. This thesis revealed that regulators considered the perspective of variation, complexity, and uncertainty in hospital settings to be important when designing the Quality Improvement Regulation. The latter resonates with resilience in healthcare concepts and contradicts previous research. The Quality Improvement Regulation contributed to context adaptation, by supporting nondetailed risk based organizing and management of quality and safety. However, hospital managers’ autonomy and adaptive capacity to tailor quality improvement efforts were imperative for the regulatory requirements to have any relevant impact on hospital practice. Limited involvement of clinicians in the regulatory development process could hamper quality improvement efforts. Inspectors could nurture learning by improving their follow up, use expert inspectors, and add more hospital selfassessment activities. This thesis highlights the importance of ensuring that any macro-level quality improvement initiatives and regulatory requirements are accompanied by appropriate resourcing, support, and advanced preparation to ensure the best possible chance of getting implemented effectively
Достоверность ссылок на научные издания: пример порождения мифов и неточностей
No full textDynamics of national and world publication activity demonstrate that the number of publications on reliability of scientific information in various fields of knowledge has increased in recent years. In the Scopus database, almost three quarters of publications related to the reliability of scientific information belong to the field of medicine, engineering and computer science; in the Web of Science the distribution across thematic areas proves to be relatively even, while in the RSCI the largest number of publications is concentrated in the area of economics.The author provides evidence that multiple references to a publication cannot guarantee its quality, moreover they even do not constitute a conclusive evidenceon the publication existence. The author refers to the situation around the monograph by Carl Martin Wiig that has been repeatedly cited in the RSCI. The monograph was allegedly translated into Russian and published in Russia in 1986. However, after searching for information in various e-catalogs, databases and clarification received from Professor K. Wiig, the existence of this monograph was rebutted. The information on the monograph was published by Russian Wikipedia in 2011, which gave the occasion for referring to the monograph in various articles, textbooks, etc. The author emphasizes that the overtrust in information loaded to Wikipedia gives rise to various myths and inaccuracies.Анализ отечественной и мировой публикационной активности показывает, что в последние годы растёт количество работ, посвящённых проблемам достоверности научной информации в различных областях знания.В базе данных Scopus почти три четверти исследований по этой теме принадлежат областям медицины, инженерии и компьютерных наук, в Web of Science наблюдается относительно равномерное распределение публикаций по тематическим областям, а в РИНЦ их наибольшее количество сосредоточено в области экономики. В статье приведены доказательства того, что множество ссылок на ту или иную публикацию не только не гарантируют её качество, но и не являются безусловным доказательством существования этой публикации. Рассмотрена ситуация, связанная с поиском многократно цитируемой в РИНЦ монографии Карла Мартина Виига (K. M. Wiig), которая якобы была переведена на русский язык и издана в России в 1986 г. Поиск в различных электронных каталогах, базах данных и информация, полученная от профессора К. М. Виига, опровергают факт существования этой монографии. В 2011 г. сведения о ней появились в русской Википедии, что послужило основанием для ссылок на работу в различных статьях, учебных пособиях и т. д. Констатировано, что излишнее доверие к информации из Википедии может порождать различные мифы и неточности
