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

Improving Service Experiences with Mobile Ethnography: The Case of two Attractions in Toronto
No full textIntroduction: Tourism destination competitiveness has been one of the main areas of research in the past twenty years (e.g., Dwyer & Kim, 2003; Enright & Newton, 2004; Ritchie & Crouch, 2003). The competitiveness of any destination relies, in part, on the quality of the customer experience that is delivered in its tourist attractions. More specifically, tourist satisfaction is based on visitors’ assessment of an experience as compared to their expectations. It is therefore essential for attractions to not only monitor visitor satisfaction, but also to continuously improve the design of the services and experiences that are provided. The purpose of this study was to conduct a service evaluation of two Toronto attractions with an innovative mobile ethnographic method. Literature: Tourism marketing is evolving at a fast pace. Because of rapid and recent technological advances (e.g., Internet access, web 2.0 technology and the ubiquity of smartphones), consumers are increasingly becoming the voice of destinations and tourist services (Dimanche, 2010). They voice their opinions in blogs, review and rate facilities, hotels, and restaurants, and share this information with pictures and videos on social media. We are shifting towards a peer-marketing approach where consumers are the most effective medium to communicate about a brand and the experiences it proposes (Buhalis & Law, 2008). As a result, it has become more important than ever for managers and marketers to focus on the quality of the experience and to work on experience design and improvement with their customers (Andrades & Dimanche, 2014). Service design has only been recently used in tourism management and tourism research (Dimanche, Keup, & Prayag, 2012; Stickdorn & Zehrer, 2009). In particular, a mobile ethnographic methodology was developed in Europe to provide destinations and service providers with alternative tool to consumer surveys that would provide richer and innovative information (Stickdorn & Frischhut, 2012). Methodology: This research uses an innovative methodology, mobile ethnography, to help improve the tourist experience in two Toronto attractions: the CN Tower and the Royal Ontario Museum. Service design is a customer-based approach to designing and improving visitor experiences. The methodology (Dimanche, Prayag, & Keup, 2014; Stickdorn & Frischhut, 2012) relies on volunteers to use their own smartphones to document their customer journeys through an App called ExperienceFellow (please visit experiencefellow.com for more information about the research tool). Other researchers have previously used and recommended mobile ethnographies (e.g., Hein, O'Donohoe, and Ryan, 2011; Tan, Foo, Goh, and Theng, 2009). Benefits of this method are that we can collect data on the service delivery site, at the time of service delivery, and in an unobtrusive way. About 50 students from a large urban university were asked to upload the App ExperienceFellow before a visit to (1) the CN Tower or (2) the Royal Ontario Museum. They were asked to identify and rate through the App the various touchpoints that mattered to them, either positively or negatively (i.e., on a 1 to 5 point scale), during the visit. By doing so, they built their own service journey and had to document each touchpoint with evidence recorded on their smartphone (i.e., a picture, a video, a text message, or a voice recording). Results: All information collected through the App was then uploaded on the ExperienceFellow server. Once all data were uploaded, the researchers could analyze the experiences through the eyes of the visitors, and make recommendations to the CN Tower and to the ROM for improvement. An application was used to graphically illustrate the visitor journeys with a storyboard including comments and testimonies made by visitors. As a result, researchers identified significant points of the service journey. Quality points to be emphasized and promoted, areas of improvement, significant problems were then synthesized in reports with recommendations for the attractions. Conclusions: This research responds to the conference call for helping destinations and attractions reimagine and reinvent customer experiences. It describes an innovative method that involves young visitors and their ability to easily use smartphones to address tourism service evaluation and identify significant service touch points, from the customers’ perspective, in the context of two urban attractions. Different from traditional service evaluation studies where visitors are asked to rate pre-identified items, this approach gives the subjects a free-hand in identifying touch points and in documenting not only how the touch points are evaluated and why, but also how the service can be improved. Rich audio-visual records of the visitor experience contribute to service improvement and service innovation. The Director of the Office of Tourism in Antibes Juan Les Pins found the tool and method useful and promising; he intends to propose to his board that this method be integrated into the DMO’s quality control process.

La gratuité : un prix !
No full textCet article aborde la question des représentations de la gratuité par les publics des musées et des monuments nationaux français. Dans le domaine culturel et dans une perspective individuelle, ces représentations sont liées à celles du prix, de l'argent et du fait de payer. La gratuité est vue comme un prix : elle supprime le coût monétaire lié à la visite mais ne change rien aux autres coûts monétaires et non monétaires dont elle modifie cependant la perception. Elle annule ce que représente le fait de payer l'entrée : visa » d'entrée dans les musées et les monuments, distance créée entre le visiteur et ces lieux, formalisation de l'engagement du visiteur. Enfin, la gratuité interpelle de façon très controversée la valeur des musées et des monuments, montrant que la gratuité, même dans une perspective individuelle, n'est pas perçue de manière univoque.Pirx, gratuité, musées et monuments

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
