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
A Multi-Language Comparison of Influences on Author Verification using Character N-Grams
No full textWe 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
A 0.12mm<sup>2</sup> Wien-Bridge Temperature Sensor with 0.1°C (3σ) Inaccuracy from -40°C to 180°C
No full text Resistor-based temperature sensors can achieve much higher resolution and energy efficiency than conventional BJT-based sensors [1], but they typically occupy more area (> 0.25 mm 2 ) and have lower operating temperatures (le 125 {circ} {C}) [2]-[4]. This work describes a 0.12mm 2 resistor-based sensor that uses a Wien-bridge (WB) filter to achieve 0.1 {circ} {C} (3 sigma) inaccuracy from - 40 {circ} {C} to 180 {circ} {C}. Compared to a state-of-the-art WB sensor [4], it occupies 6 × less area and achieves comparable relative accuracy over a 76% wider operating range.

A ±25A Versatile Shunt-Based Current Sensor with 10kHz Bandwidth and ±0.25% Gain Error from -40°C to 85°C Using 2-Current Calibration
No full textAccurate current sensing is critical in many industrial applications, such as battery management and motor control. Precise shunt-based current sensors have been reported with gain errors of less than 1% over the industrial temperature range (-40°C to 85°C) [1]–[4]. However, since they are intended for coulomb counting, their bandwidth is limited to a few tens of Hz, making them unsuitable for battery impedance or motor-current sensing. This paper presents a current sensor with a wide (10kHz) bandwidth and a tunable temperature compensation scheme (TCS), which allows it to be flexibly used with different types of shunts while maintaining high accuracy. A low-cost room-temperature calibration scheme is proposed to optimize gain flatness over temperature by exploiting the shunt's self-heating at large currents. Over the industrial temperature range and a ±25A current range, it achieves state-of-the-art gain error (±0.25%) with both low-cost PCB and stable metal-alloy shunts.Green Open Access added to TU Delft Institutional Repository 'You share, we take care!' - Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Electronic InstrumentationMicroelectronic

Frontline policy implementation in public organizations : A sociological analysis of the ‘how and why’ of implementation gaps
No full textBackground and aims Innovation is promoted in politics and public service organizations as an essential factor for meeting the demands of society. How new policies or strategies can be implemented as intended in complex multi-level public organizations is a major practical and academic puzzle. We know from extensive research that there is often a gap between central policy formulations and their implementation in practice (Hill & Hupe, 2003; Hupe, 2014) created by frontline workers exercise of discretion and their outcomes (Lipsky, 1980, 2010). However, there is a need for empirical
research on the ‘how and why’ of street-level implementation (Hupe, 2014) such as ‘how the workers actually arrive at their decisions’ (Goldman & Foldy, 2015 p.169), as well as the use of multi-leveled perspectives to investigate the problem of implementation gaps (Hupe, 2014). The thesis aims to investigate mismatches between centrally directed policy measures and their implementation on the operational level. Introducing the concept of ‘resistance-driven innovation’, the thesis challenges the normative tendency of viewing implementation gaps as implementation failures (Hupe & Hill,
2016). In order to realize the thesis’ aim, a critical realist informed case study was used to explore the top-down implementation process of a specific work inclusion policy measure within the Norwegian Employment and Welfare Services (NAV). The thesis aim is operationalized into research questions and dealt with in three separate articles as well as summarized and elaborated on in chapters 5, 6 and 7 as follows:
a. What do the multi-level implementation context and process of the specific policy measure in NAV look like?
b. How did frontline staff at the case office of NAV perceive and respond to the implementation efforts of the policy measure in focus?
c. Why was the Facilitation Guarantee not implemented as intended at the case office?
d. What are the theoretical implications, mainly for the street-level policy implementation research field, but also for the fields of institutional logics and employee-based innovation?
e. What are the implications for the planning and management of implementation processes?
Research design. The critical realist informed case study explores the topdown implementation process of the work inclusion policy measure called the Facilitation Guarantee within NAV, tracing it through all levels of NAV to a specific frontline case office. The case study included two successive and interacting main phases: first, the exploration of the implementation context, process and strategies of the policy measure at the various hierarchical levels of NAV, and then exploration and explanation of reactions to its implementation instructions among the frontline employees at the selected case office. The case study included in-depth semi-structured interviews, document studies and meeting observations. The case study included methods of in-depth semi-structured interviews, document studies and meeting observations. For the first phase, data material was collected during a 14 month period, December 2014 – January 2016 consisting of an exploratory document study of internal reports, guidelines, instructions etc. as well as 21 semi-structured interviews of 16 informants distributed at various levels of the organization, including managers and implementation coordinators. The second phase of the study, focusing on the selected frontline case office during the 4 last months of 2015, included 11 one-to-two hour-long interviews with frontline employees, as well as interviews from three of the informants from the first phase. The interviews were supplemented with observations from 24 case and department meetings. Together, the two phases consisted of a total of 32 interviews with 27 informants. Drawing on a CR informed methodology (e.g. Edwards, O'Mahoney, & Vincent, 2014) the empirical findings from the interviews and observations were analyzed in the light of the wider contextual understanding that the full case study provided. The subsequent findings were continuously analyzed to explore mechanisms that could best contribute to an explanation of the way that the implementation instructions were met by the frontline employees (Belfrage & Hauf, 2017)
