Market Reform, Regional Energy and Popular Representation: Evidence from Post-Soviet Russia
This article investigates the relative impact of regional energy production on the energy voting choices of State Duma deputies between 1994 and 2003, controlling for other factors such as party affiliation, electoral mandate, committee membership and socio-demographic parameters. We apply Poole’s optimal classification method of roll call votes using an ordered probit model to explain energy market reform in the first decade of Russia’s democratic transition. Our main finding is that the gas production factor is inter temporally important in the formation of the deputies’ legislative choices and shows Gazprom’s strategic position in the post-Soviet Russian economy. The oil production factor is variably significant in the two first Dumas, when the main legislative debates on oil privatization occur. The energy committee membership tends to consistently explain pro-reform voting choices. The pro-and anti-reform poles observed in our Poole-based single dimensional scale are not necessarily connected with liberal and state-oriented policies respectively.energy regulation, market reform, energy resources, roll call votes, legislative politics, State Duma, Russia
Implementation of problem-based learning in nursing education: a Malawian case study
Includes abstract.Includes bibliographical references.Problem-based learning (PBL) is a teaching and learning approach that is known to facilitate life-long learning, problem solving, self-directed learning, critical thinking skills and student motivation (Hung, Jonassen & Liu 2006:486; Ehrenberg & Haggblom 2007:67). It is also renowned for the promotion and integration of knowledge. PBL was introduced in Malawian nursing education six years ago; however, its implementation apparently has been very slow throughout the country. The primary purpose of this study was to explore, analyse and describe characteristics that facilitated implementation of PBL in the identified college as a case study. The secondary purpose was to utilise the data gathered from the identified college as a case study to identify a set of critical factors that could guide implementation of PBL in nursing education in Malawi. This was an exploratory and descriptive qualitative case study using an ethnographic approach and guided by the theoretical framework of sociotechnical systems. Purposive sampling technique was employed to select the college, nine participants and documents for review. Three data sources were utilised: semi-structured interviews, participant observation and document reviews. Ethnographic data analysis was done following the four steps of data analysis as described by Spradley (1979), and trustworthiness was ensured utilising the criteria proposed by Lincoln and Guba. Four themes emerged as characteristics that enhanced implementation of PBL: having a goal to achieve, resources for the organisation, influence on the organisation, and critical success factors. These four themes had the following subthemes and categories: (i) having a goal - subthemes were; producing life-long learners, review of the curriculum, gradual introduction of PBL and embracing the PBL. (ii) Resources for the organisation – subthemes were; committed management and leadership, skills development of staff, having staff with the same values, additional staff, having technological and material resources, and staff knowledge of the curriculum. (iii) Influences on the organisation – subthemes were; social influence, economic influence and political influence. (iv) Critical success factors – subthemes were; staff involvement in planning and communication, motivation and commitment of staff, collaboration with other colleges and organisations, and recognition of the need for change
Going Beyond Counting First Authors in Author Co-citation Analysis
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

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
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
About the Structure of the Boyar Duma and Palace Administration in the Period of Boyar Rulling in the 30s–40s of the 16th Century
Introduction. The main purpose of the publication is to recreate members of the Boyar duma and palace administration, to reconstruct the high-ranking structure of the top of the Sovereign court during the period of Boyar rulling on the basis of all published and archival documents.
Methods and materials. The method of genealogical analysis and the method of prosopografical investigation are applied to the research of the duma and palace composition. The author uses information from various editions of genealogical books, Gosudarev rodoslovets of 1555, lists of noble families of the late 17th c., charge and ambassadorial books, acts on land, chronicles, supplementary books of monasteries.
Analysis. The author reveals the features of the highest appointments, dynamics of appointments to the Boyar duma and palace administration during the political crisis of 1533–1547.
Results. The author notes that new appointments in the Boyar duma and palace administration depended not only on the developed political environment, but also on the patrimonial order of inheritance of the highest ranks in a narrow circle of boyar clans notable and close to the throne. One more important conclusion received as a result of the research is that during the studied period powerful aristocrats possessed two ranks of boyars (okolnichy and dvoretsky) at the same time. The explanation of this can be found, perhaps, in the process of bureaucratization of management noted by M.M. Krom, which was expressed in isolation of government from the carrier of the supreme power and formation of the professional group of managers which concentrated the most significant administrative functions in their hands
Evaluation of Tizian overlays by means of a swept source optical coherence tomography system
The teeth affected by pathologic attrition can be restored by a minimally invasive approach, using Tizian overlays. In this study we prove the advantages of a fast swept source (SS) OCT system in the evaluation of Tizian overlays placed in an environment characterized by high occlusal forces. 12 maxillary first premolars were extracted and prepared for overlays. The Tizian overlays were subjected to 3000 alternating cycles of thermo-cycling (from -10°C to +50°C) and to mechanical occlusal overloads (at 800 N). A fast SS OCT system was used to evaluate the Tizian overlays before and after the mechanical and thermal straining. The SS (Axsun Technologies, Billerica, MA) has a central wavelength of 1060 nm, sweeping range of 106 nm (quoted at 10 dB) and a 100 kHz line rate. The depth resolution of the system, measured experimentally in air was 10 ?m. The imaging system used for this study offers high spatial resolutions in both directions, transversal and longitudinal of around 10 ?m, a high sensitivity, and it is also able to acquire entire tridimensional (3D)/volume reconstructions as fast as 2.5 s. Once the full dataset was acquired, rendered high resolutions en-face projections could be produced. Using them, the overlay (i.e., cement) abutment tooth interfaces were remarked both on B-scans/two-dimensional (2D) sections and in the 3D reconstructions. Using the system several open interfaces were possible to detect. The fast SS OCT system thus proves useful in the evaluation of zirconia reinforced composite overlays, placed in an environment characterized by high occlusal forces. © (2016) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).

A Multi-Language Comparison of Influences on Author Verification using Character N-Grams
We create a new multi-language corpus for author verification based on Wikipedia talkpages, and evaluate the influence that differences in topic and time have on character n-gram author profiles. Topic alignment between two texts is found to increase author verification precision, and an authors writing style is found to change over time, but not more significantly after 3 years than after 1 year.Information ArchitectureWISElectrical Engineering, Mathematics and Computer Scienc
