Recent research in the populism literature has devoted considerable efforts to the conceptualisation and examination of populism on the individual level, that is, populist attitudes. Despite rapid progress in the field, questions of adequate measurement and empirical evaluation of measures of populist attitudes remain scarce. Seeking to remedy these shortcomings, we apply a cross-national measurement model, using item response theory, to six established and two new populist indicators. Drawing on a cross-national survey (nine European countries, n = 18,368), we engage in a four-folded analysis. First, we examine the commonly used 6-item populism scale. Second, we expand the measurement with two novel items. Third, we use the improved 8-item populism scale to further refine equally comprehensive but more concise and parsimonious populist measurements. Finally, we externally validate these sub-scales and find that some of the proposed sub-scales outperform the initial 6- and 8-item scales. We conclude that existing measures of populism capture moderate populist attitudes, but face difficulties measuring more extreme levels, while the individual information of some of the populist items remains limited. Altogether, this provides several interesting routes for future research, both within and between countries.

Abstract Background Healthcare organizations around the world are striving to achieve transformational performance improvement, often through adopting process improvement methodologies such as Lean management. Indeed, Lean management has been implemented in hospitals in many countries. But despite a shared methodology and the potential benefit of benchmarking lean implementation and its effects on hospital performance, cross-national Lean benchmarking is rare. Healthcare organisations in different countries operate in very different contexts, including different healthcare system models, and these differences may be perceived as limiting the ability of improvers to benchmark Lean implementation and related organisational performance. However, there is no empirical research available on the international relevance and applicability of Lean implementation and hospital performance measures. To begin to understand the opportunities and limitations related to cross-national benchmarking of Lean in hospitals, we conducted a cross-national case study of the relevance and applicability of measures of Lean implementation in hospitals and hospital performance. Methods We report an exploratory case study of the relevance of Lean implementation measures and the applicability of hospital performance measures using quantitative comparisons of data from Hospital District of XX XX University Hospital in Finland and a sample of 75 large academic hospitals in the United States. Results The relevance of Lean-related measures was high across the two countries: almost 90% of the items developed for a US survey were relevant and available from XX. A majority of the US-based measures for financial performance (66.7%), service provision/utilisation (100.0%), and service provision/care processes (60.0%) were available from XX. Differences in patient satisfaction measures prevented comparisons between XX and the US. Of 18 clinical outcome measures, only four (22%) were not comparable. Clinical outcome measures were less affected by the differences in healthcare system models than measures related to service provision and financial performance. Conclusions Lean implementation measures are highly relevant in healthcare organisations operating in the United States and Finland, as is the applicability of a variety of performance improvement measures. Cross-national benchmarking in Lean healthcare is feasible, but a careful assessment of contextual factors, including the healthcare system model, and their impact on the applicability and relevance of chosen benchmarking measures is necessary. The differences between the US and Finnish healthcare system models is most clearly reflected in financial performance measures and care process measures.

Abstract Background: The Warwick Edinburgh Mental Well-Being Scale (WEMWBS) is a measure of subjective well-being and assesses eudemonic and hedonic aspects of well-being. However, differential scoring of the WEMWBS across gender and its precision of measurement has not been examined. The present study assesses the psychometric properties of the WEMWBS using Measurement Invariance (MI) between males and females and Item Response Theory (IRT) analyses. Method: A community sample of 386 adults from the United States of America (USA), United Kingdom, Ireland, Australia, New Zealand, and Canada were assessed online (N = 394, 54.8% men, 43.1% women, Mage = 27.48, SD = 5.57). Results: MI analyses observed invariance across males and females at the configural level and metric level but non-invariance at the scalar level. The graded response model conducted to observe item properties indicated that all items demonstrated, although variable, sufficient discrimination capacity.Conclusions: Gender comparisons based on WEMWBS scores should be cautiously interpreted for specific items that demonstrate different scalar scales and similar scores indicate different severity. The items showed increased reliability for latent levels of ∓ 2 SD from the mean level of SWB. The WEMWBS may also not perform well for clinically low and high levels of SWB. Including assessments for clinical cases may optimise the use of the WEMWBS.

Not enough has been written about the import, adaptation, and application of urban environmental and planning policies from abroad into the United States. Even less has been written about the voluntary cross-national transfer and application of environmental policies by American subnational actors and institutions. It is our intent to begin redressing this by discussing the transfer of urban environmental and planning policies from Germany to the United States during the early part of the 21st century. This discussion is informed by data drawn from governmental reports and planning statements and over thirty-five interviews with US urban environmental and planning practitioners operating in Germany and the United States. What we discover is that, unlike more rational models of policy transfer, the voluntary importation of environmental and planning policies into the US is seldom a problem-focused, goal-oriented process. Rather, what we find is that a better depiction of the transfer and adoption process is of a relatively anarchic situation. This appears to occur due to a range of institutional and cultural filters that predispose American policy makers against gathering (and using) information and experiences from abroad. We find that this filtering process tends to encourage policy makers to discount (or reject outright) the usefulness of overseas models and that, when they do engage in this process, any information gathered appears to be based less upon well-researched and analyzed data than embedded ‘tacit’ knowledge.

In this panel we combine longitudinal and cross-national studies of social media in election campaigns, expanding the time span as well as number of countries compared to former studies. The four papers present longitudinal studies, covering multiple election cycles from four different countries: Australia, the United States of America, Denmark and Sweden. By including these cases we focus on countries considered to be “first movers” when it comes to the digitization and internetization of the political life. As such, they are “most similar cases”. However, they also have different political systems: the US and Australia are characterized by a Westminster system dominated by a few large parties and a tradition of strong confrontation between government and opposition, whereas Denmark and Sweden are multi-party systems with a tradition of collaboration and coalition governments. Further, the countries’ media systems, as defined by Hallin & Mancini (2004), differ significantly; the US is characterized by a commercialized American media system with little role for public service broadcasters, Denmark and Sweden have very strong public service media, and Australia has elements of both these systems. Technologically, the four countries might be similar, but politically and in terms of media systems, they differ. Thus, studies of the four countries form a diverse yet solid set of cases for exploring the growing (and changing) role of social media in national elections. The papers address such issues by various methods and perspectives, from large-scale big data analyses of tweets to content analyses of Facebook pages and surveys among citizens. From different angles, the four papers circle around the same topics: do social media contribute to narrowing or widening the often-discussed gap between citizens and politicians? Does the increasing use (and changing character) of social media in election campaigns facilitate increased trust or rather a radicalized and more negative discourse? And do citizens feel more empowered and enlightened in a democratic sense? The Australian case study is based on a comprehensive analysis of interactions around candidates’ Twitter accounts, drawing on state-of-the-art methods. It stretches across three election cycles. It presents new evidence both on the use of Twitter in political campaigning in Australia, and on the public response to this use, not at least in the light of the overall context of a decline in trust towards the political system, in Australia and elsewhere. The US case study examines negativity, incivility, and intolerance expressed by candidates running for governor in 2014 as compared with 2018. In between those two election cycles, the United States had the remarkable presidential campaign of 2016, with an unprecedented volume and style of negative campaigning unseen in modern campaigning. This study thus asks whether the 2018 candidates were more negative and uncivil than their counterparts who ran in 2014. Results will illuminate the nature of political incivility and whether there is a coarseness of political discourse in the United States. The Danish case study is based on surveys of citizens’ Internet use / social media use across four elections, covering a time span of 12 years. It adds to an understanding of the growing use of social media but more importantly it investigates how citizens experienced effects of social media as tools for agenda-setting and efficacy, the latter understood as increased reflection and enlightenment. The Swedish case study covers three Swedish national elections, in 2010, 2014 and 2018. The research question is: how are viral posts from political parties on Facebook changing over time? By answering that question, the author can track the consequences of increased platformization of politics as well as an increased targeting towards the needs and wants of the audience, through what some will call populism. The studies all cover more or less the last decade. This represents a time span during which social media have matured and have come to play an increasing role in citizens’ daily lives. The contributions are interesting country-based case studies in themselves, but through this panel we seek to engage the audience in a discussion of the developments expected for the coming years.

Structure of the Observed Learning Outcome (SOLO) science superitems were examined from the perspectives of Guttman Scaling (deterministic) and Item Response Theory (probabilistic). Differences between the measurement bases for the two approaches, and the results for a small case study, are reported. In general, the analyses confirmed the hypothesised patterns of learners' responses, but also revealed some discrepancies in particular superitems that can be interpreted within the framework of the SOLO taxonomy.

Abstract Background The present study considers a measure of positive body image, the Body Appreciation Scale-2, which assesses acceptance and/or favourable opinions towards the body (BAS-2). Potential variations of the psychometric properties of the scale across males and females, as well as across its different items invite for further investigation. The present study contributes to this area of knowledge via the employment of gender Measurement Invariance (MI) and Item Response Theory (IRT) analyses. Methods A group of 386 adults from Australia, Canada, New Zealand, Ireland, the United Kingdom, and the United States of America (USA) were assessed online (N = 394, 54.8% men, 43.1% women, Mage = 27.48; SD = 5.57). Results MI analyses observed invariance across males and females at the configural level, and non-invariance at the metric level. Further, the graded response model employed to observe IRT properties indicated that all items demonstrated, although variable, strong discrimination capacity. Conclusions The items showed increased reliability for latent levels of ∓ 2 SD from the mean level of Body Appreciation (BA). Gender comparisons based on BAS-2 should be cautiously interpreted for selected items, due to demonstrating different metric scales and same scores indicating different severity. The BAS-2 may also not perform well for clinically low and high BA levels. Thus, it should optimally be accompanied by clinical interviews for formal assessment in such cases.
