Methodological insights into multilevel analysis of individual heterogeneity and discriminatory accuracy: An empirical examination of the effects of strata configurations on between-stratum variance and of fixed effects across hierarchical levels.

This study aims to advance the Multilevel Analysis of Individual Heterogeneity and Discriminatory Accuracy (MAIHDA) approach by addressing two key questions. First, it investigates the impact of using increasingly complex combinations of variables to create intersectional strata on between-stratum variance, measured by the variance partitioning coefficients (VPCs). Second, it examines the stability of coefficients for fixed effects across models with an increasing number of hierarchical levels. The analysis is performed using data from a survey of over 42,000 respondents on the prevalence of gender-based violence in European research organisations conducted in 2022. Results indicate that the number of intersectional strata is not significantly related to the proportion of the total variance attributable to the variance between intersectional strata in the MAIHDA approach. Moreover, the coefficients remain relatively stable and consistent across models with increasing complexity, where levels about organisations and countries are added. The analysis concludes that the MAIHDA approach can be flexibly applied for different research purposes, either to better account for structures of power and inequality; or to provide intersectionality-sensitive estimates. The findings underscore the need for researchers to clarify the specific aims of using MAIHDA, whether descriptive or inferential, and highlight the approach's versatility in addressing intersectionality within quantitative research. The study contributes to the literature by offering empirical evidence on the methodological considerations in applying the MAIHDA approach, thereby aiding in its more effective use for intersectional research.

The Role of Intersectionality and Context in Measuring Gender-Based Violence in Universities and Research-Performing Organizations in Europe for the Development of Inclusive Structural Interventions.

The aim of the article is to discuss how thinking about gender-based violence intersectionally and in context can not only enrich our understanding but also lead to transformative change in organizations. The article argues that to better understand gender-based violence in universities and research institutions, analyses need to be intersectional and contextual. Such approaches go beyond binary understandings of gender and narrow legalistic definitions of gender-based violence. The article reflects on how to operationalize this to derive starting points for intersectional categories to consider and contextual factors to measure at micro-, meso-, and macro-levels. It concludes that a multilevel intersectional analysis leads to more nuanced knowledge on experiences of gender-based violence and is, therefore, better equipped to inform the development of measures to eradicate the problem in an inclusive way.

Certifying Gender Equality in Research: Lessons Learnt From Athena SWAN and Total E-Quality Award Schemes.

In the past 2 decades, many Certification and Award schemes (CAS) related to gender equality, diversity and inclusion have emerged in the higher education, research and industry sectors. According to a recent report, there are as many as 113 CAS which have been identified across Europe and beyond. These CAS aim at addressing inequalities in relation to the grounds of sex, gender, race, sexual orientation, and disability among others. The high number of CAS, and their continued growth, has taken place in parallel to the shift of policies and efforts from "fixing individuals" to "fixing the system." In these schemes, gender equality is often understood as a structural, systemic challenge, with a recognition that advancing gender equality is complex and requires drivers and interventions at micro, meso and macro level. Studies focused on analysing and evaluating gender equality initiatives in higher education have been scarce, and often limited to specific schemes. This paper aims to fill this gap by providing a better understanding of the CAS landscape through comparing two of the main gender equality schemes used by research-performing organisations in Europe Athena SWAN (in the UK) and Total E-Quality Award (in Germany). Based on qualitative interviews with stakeholders across Europe and document analysis, this paper focuses on strengths, challenges faced by and the impact of these CAS. This comparative exercise highlights particular learning points that can inform potential reviews of existing schemes and/or the development of new schemes such as a Europe-wide scheme. The latter is the focus of a Horizon 2020 project entitled CASPER (Certification-Award Systems to Promote Gender Equality in Research), which aims at making recommendations to the European Commission as to the feasibility of a Europe-wide CAS for gender equality in research organisations.

Undoing the 'Nordic Paradox': Factors affecting rates of disclosed violence against women across the EU.

Measuring violence against women raises methodological questions, as well as the wider question of how to understand violence and locate it in relation to a societal context. This is all the more relevant given that measurement of violence against women in the EU has made an interesting phenomenon apparent, the so-called 'Nordic Paradox', whereby prevalence is higher in more gender equal countries. This article examines this phenomenon by exploring a range of factors-methodological, demographic and societal-to contextualise disclosed levels of violence. The analysis makes use of a multilevel analytic approach to take into account how macro and micro levels contribute to the prevalence of violence. The intercepts are then used to illustrate how taking these into account might provide an alternative ranking of levels of violence against women in EU countries. The results show that the 'Nordic Paradox' disappears-and can be undone-when factors at individual and country levels are considered. We conclude that the 'Nordic Paradox' cannot be understood independently from a wider pattern of violence in society, and should be seen as connected and co-constituted in specific formations, domains or regimes of violence. Our results show that the use of multi-level models can provide new insights into the factors that may be related to disclosed prevalence of violence against women. This can generate a better understanding of how violence against women functions as a system, and in turn inform better policy responses.

Sensor-based proximity metrics for team research. A validation study across three organizational contexts.

Wearable sensors are becoming increasingly popular in organizational research. Although validation studies that examine sensor data in conjunction with established social and psychological constructs are becoming more frequent, they are usually limited for two reasons: first, most validation studies are carried out under laboratory settings. Only a handful of studies have been carried out in real-world organizational environments. Second, for those studies carried out in field settings, reported findings are derived from a single case only, thus seriously limiting the possibility of studying the influence of contextual factors on sensor-based measurements. This article presents a validation study of expressive and instrumental ties across nine relatively small R&D teams. The convergent validity of Bluetooth (BT) detections is reported for friendship and advice-seeking ties under three organizational contexts: research labs, private companies, and university-based teams. Results show that, in general, BT detections correlated strongly with self-reported measurements. However, the organizational context affects both the strength of the observed correlation and its direction. Whereas advice-seeking ties generally occur in close spatial proximity and are best identified in university environments, friendship relationships occur at a greater spatial distance, especially in research labs. We conclude with recommendations for fine-tuning the validity of sensor measurements by carefully examining the opportunities for organizational embedding in relation to the research question and collecting complementary data through mixed-method research designs.

The computed tomography adrenal wash-out analysis properly classifies cortisol secreting adrenocortical adenomas.

PURPOSE: Adrenocortical lesions are characterized through imaging, hormonal and histopathological analysis. Our aim was to compare the radiological features of adrenocortical lesions with their cortisol-secreting status and histopathological Weiss score. METHODS: Seventy five patients operated between 2004 and 2016 in the University Hospital of Nancy for either adrenocortical carcinomas (ACC) or adrenocortical adenomas (ACA) were enrolled in this study. We collected cortisol parameters, Computed Tomography (CT) scans (unenhanced density, wash-out (WO) analysis) and 18F-Fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) datas. The histopathological Weiss score ultimately differentiates ACA (score ≤ 2) from ACC (score ≥ 3). One-way ANOVA, Fisher's exact and unpaired t tests were used for statistical analysis with significancy reached at p < 0.05. RESULTS: There were 23 ACC and 52 ACA with 40 patients (53%) who had an autonomous secretion of cortisol. On CT scan, ACC were larger compared to ACA (108 vs. 37 mm, p < 0.0001). A roughly similar proportion of cortisol-secreting (22/25) and non-secreting (15/19) ACA were atypical (i.e., unenhanced density value ≥ 10 Hounsfield Units [HU]), however 85% of cortisol-secreting vs. 40% of non-secreting ACA were classified as benigns by the relative WO analysis (p = 0.08). Likewise, there was a trend for a higher 18F-FDG uptake in cortisol-secreting ACA compared to non-secreting ACA (p = 0.053). CONCLUSIONS: The relative adrenal WO analysis consolidates the benign nature of an ACA, especially in case of cortisol oversecretion, a condition known to compromise the diagnostic accuracy of the 10 HU unenhanced CT attenuation threshold.

Ocular symptoms are not predictive of ophthalmologic inflammation in inflammatory bowel disease.

BACKGROUND: Ocular manifestations are frequent in patients with inflammatory bowel disease. AIM: To evaluate for the first time the value of ocular symptoms in predicting ophthalmologic inflammation in inflammatory bowel disease. METHODS: All consecutive inflammatory bowel disease patients seen in the Department of Gastroenterology (Nancy, University Hospital, France) between April 2009 and July 2011 were interviewed for this cross-sectional study using a pre-established questionnaire. If the patient had at least one ocular symptom, he systematically underwent an ophthalmologic examination (visual acuity, Break-Up Time test, Schirmer Test, slit-lamp exam with fundus examination). RESULTS: This cross-sectional survey was completed by 305 patients: 169 were women (55.2%), 228 had Crohn's disease (74.5%). Ninety-eight patients (32%) reported at least one ocular symptom: ocular irritation (56.8%), red eye (40.5%), blurred vision (37.8%), progressive visual loss (34.4%), ocular pain (31.1%), myodesopsia (23.3%), eyelid secretion (12.2%), dry eye (9.5%), watering (6.8%), diplopia (5.4%), metamorphopsia (4%), and sudden visual loss (4%). Following ophthalmologic examination (n=74), 41.9% patients had evidence of dry eye (n=31), 14.9% blepharitis (n=11) and 1.4% scleritis (n=1). No uveitis was reported. CONCLUSION: Ocular symptoms are frequent in inflammatory bowel disease, but are non-specific and rarely associated with ocular inflammation. Systematic ocular symptoms assessment is of poor value for diagnosing ocular inflammation in inflammatory bowel disease.
