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
Revealing the manifestations of neoliberalism in academia: Academic collective action in Turkey
No full textCoskan C, Acar YG, Bayad A. Revealing the manifestations of neoliberalism in academia: Academic collective action in Turkey. Journal of Social and Political Psychology . 2021;9(2):401-418.Academic Collective Action (ACA) stands as a small-scale collective action for social change toward liberation, independence and equity in academia. Academic collectives in Turkey, as an example of ACA, prefigure building academia outside the university by emphasizing the extent to which neoliberal academia has already prepared the groundwork for more recent waves of oppression. In this research, we aim to reveal the manifestations of neoliberalism in ACA as captured with prominent social/political psychological concepts of collective action. We conducted semi-structured interviews with 21 dismissed academics to understand the social and political psychological processes in academic collectives. The narrations of ACA were accompanied by manifestations of neoliberalism as experienced by dismissed academics. We found that, as follows from the existing conceptual tools of collective action, neoliberalism serves as an embedded contextual factor in the process of ACA. This becomes mostly visible for grievances but also for collective identifications, politicization, motivations, finding/allocating resources and sustaining academic collectives. We provide a preliminary basis to understand the role of neoliberalism in organization, mobilization and empowerment dynamics of collective action

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.

Locals' support for integration policies and asylum seekers' rights: Exploring a normative model of support for Syrians in Turkey
No full textDuman Y, Coskan C. Locals' support for integration policies and asylum seekers' rights: Exploring a normative model of support for Syrians in Turkey. Studies in Ethnicity and Nationalism . 2023.Syrian asylum seekers in Turkey have been trying to adapt to their new life circumstances despite unclear integration and resettlement policies and high levels of discrimination and exclusion. We argue that fostering integration and asylum seekers' rights requires a bottom-up normative approach that considers members of the receiving society as active agents of these processes. Accordingly, in this study, we investigated the role of normative social context as well as sociopsychological antecedents among citizens of Turkey in facilitating their support for governmental integration policies and Syrian asylum seekers' rights. A survey study was conducted with 202 residents in three cities, namely Bursa, Mardin, and Hatay, representing different geographical, ethnic, and cultural components in Turkey (i.e., Turkish, Kurdish, Arab, and Kurdish-Arab). We specifically examined how citizens' life concerns, perceptions of pro-diversity norms in their city, and generalized attitudes toward minorities relate to their support for integration policies and Syrians' rights. Furthermore, we tested the mediating roles of valuing intergroup contact with Syrians as well as accepting their presence and opposing their assimilation. Serial mediation analyses indicated that generalized positive feelings toward other minority groups predict higher support for integration policies, Syrians' rights, as well as higher expectations of support for Syrians from fellow citizens, first through valuing contact with Syrians and second, through higher acceptance of Syrians' stay and lower expectations of assimilation. However, perceptions of pro-diversity norms predicted lower support for integration policies, Syrians' rights, as well as lower expectations of support for Syrians from fellow citizens, first through devaluing contact with Syrians and second, through lower acceptance of Syrians' stay and higher expectations of assimilation. These findings suggest that attitudes toward existing minority groups can define the social context and sociopsychological antecedents that would foster Syrians' adaptation to life by taking on board members of the receiving society. However, they also indicate caution regarding the taken-for-granted role of pro-diversity beliefs among the residents, especially in societies with complex intergroup relations
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
“If I die, my children will pursue this case”: Counternarratives of power in Kurds.
No full textCoskan C, Sen E. "If I Die, My Children Will Pursue This Case": Counternarratives of Power in Kurds. Peace and Conflict: Journal of Peace Psychology. 2023;29(2):135-154.Despite hundreds of years of forced and violent assimilation from multiple sources, Kurds continue to exist as dissidents, progressing their ethnonational and cultural ways of being through an anticolonial resistance. Honoring the Kurdish existence by resistance, our motivation is to bring into light the "Kurdish power" that enables this kind of resistance within the Turkish nation-state borders. Guided by critical race theory and decolonial approach, we pursue Kurds' counternarratives of power to dismantle the hegemonic representations of power and oppression while exposing systematic and systemic dynamics of racism. We interviewed 16 Kurds in Van and Istanbul, and we asked their understanding of power and their political reflections. By combining counternarrative and thematic analyses, we provide a multifocal, multisourced understanding of power, shaped around the multitudes of Kurdishness against Turkish oppression and violence. Counternarrators' refusals of hegemonic oppression are intertwined with a strong belief in collectivity, a sense of nationhood is intertwined with multifragmentality, and imaginations of future are intertwined with agency, existence, and oppression
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
