Preference changes and index number theory

AbstractThe economic approach to the cost of living index assumes that consumer preferences remain constant over time. This assumption poses little risk in calculating a short‐run intertemporal bilateral price index. The assumption, however, breaks down in the case of a fixed‐based time series index spanning a long period and in the context of international comparison. The economic analysis of preference changes, however, is not well‐established. In this paper, we review the economic approach in index numbers under preference changes. Suggestions are made on how to approach the problem and their implications for the measurement of price and quantity indices.

The Pandemic and Counterurbanization: A Comparison of Sweden and Slovenia

Based on the concept of teleworkability, its sluggish determinants of industry structure and workplace culture, and the change in people’s valuation of rural amenities that happened during the pandemic, this paper analyzes their possible influence on counterurbanization during the pandemic in Sweden and Slovenia. We found signs of open (migration) as well as “hidden” counterurbanization (unregistered rural living) in both countries, stronger in Sweden than in Slovenia, and we found indications that industrial structure and national workplace cultures contributed to differences in the strength of the counterurbanization. In both countries, we found indications that the pandemic contributed to a shift in people’s relative valuation of rural vs. urban amenities. Thus, while the sluggish factors contributed to differences in teleworkability between Sweden and Slovenia, the chock implied similar reactions in the shift of the valuation of amenities. Ever since the counterurbanization of the 1970s, studies of the phenomenon have almost solely been completed within countries, and the few international comparisons that have been completed have been based on comparing the results of the national studies. This study is one of the very first ones that compares counterurbanization and its driving forces in two countries within the same analytical framework.

Definitions, terminology and standards for reporting of births and deaths in the perinatal period: International Classification of Diseases (ICD-11).

Despite efforts to reduce stillbirths and neonatal deaths, inconsistent definitions and reporting practices continue to hamper global progress. Existing data frequently being limited in terms of quality and comparability across countries. This paper addresses this critical issue by outlining the new International Classification of Disease (ICD-11) recommendations for standardized recording and reporting of perinatal deaths to improve data accuracy and international comparison. Key advancements in ICD-11 include using gestational age as the primary threshold to for reporting, clearer guidance on measurement and recording of gestational age, and reporting mortality rates by gestational age subgroups to enable country comparisons to include similar populations (e.g., all births from 154 days [22+0 weeks] or from 196 days [28+0 weeks]). Furthermore, the revised ICD-11 guidance provides further clarification around the exclusion of terminations of pregnancy (induced abortions) from perinatal mortality statistics. Implementing standardized recording and reporting methods laid out in ICD-11 will be crucial for accurate global data on stillbirths and perinatal deaths. Such high-quality data would both allow appropriate regional and international comparisons to be made and serve as a resource to improve clinical practice and epidemiological and health surveillance, enabling focusing of limited programmatic and research funds towards ending preventable deaths and improving outcomes for every woman and every baby, everywhere.

Descriptive analysis of the steering potential in the internal medicine in Germany based on an international comparison

Healthcare in Germany is not always needs-based and has considerable potential for optimization. Internal medicine (IM) plays aspecial role in the German healthcare system due to its long tradition. Against this background, alook at the optimization potential to achieve better quality and higher efficiency care seems particularly relevant. Based on an international comparison and taking ambulatory care-sensitive conditions (ACSC) into account, this study aims to identify the steering potential in IM and to discuss it in the context of current reform plans. The descriptive analysis was carried out as part of areport commissioned by the German Society of Internal Medicine and is based on data from the Federal Statistical Office and Eurostat as well as the ACSC catalogue developed for Germany. The top 10 reasons for inpatient treatment in IM include 7 ACSCs. These diagnoses account for almost one quarter of cases and treatment days and mostly relate to cardiology. The international comparison including numerous other indications shows that other countries have both significantly fewer cases and shorter lengths of stay for most indications. The results show that IM in Germany has considerable potential for optimization of inpatient care. In light of the regional variation in service providers and utilization as well as the potential for avoiding inpatient treatment, the current reform plans represent an opportunity for the reorientation of IM. Not least because of its high relevance, also in terms of numbers, it is therefore right and important that it is given such strong consideration within the reform plans.

Making public or quiet listening? Media logics and public inquiries into the abuse of children

This article examines the tensions between ‘publicness’ and ‘privacy’ in national commissions of inquiry. Through the insights of those who worked deep inside Australia's landmark Royal Commission into Institutional Responses to Child Sexual Abuse (RCIRCSA, 2013–2017), and the evidence provided in its final report, we explore the organisational and media logics of the Commission's highly publicised public hearings, and the ‘quiet’ institutional listening practices of its private sessions and engagement with marginalised communities. Royal Commissions are an important mechanism for raising awareness of past crimes on the public agenda. Our research finds that while the revelatory outcomes of the RCIRCSA have been well documented, its private sessions, engagement and research are less well understood. We argue ‘publicness’ is a relatively unchallenged good that is enacted through news media and the royal commission process, but media logics can limit their capacity to address the ongoing causes and impacts of child sexual abuse against the most impacted children. Participants reflected on the media logics that drove strategic decisions to ‘make public’ some cases and institutions, while others remained in the Commission's private realm. The article concludes that the confidential sharing of evidence has been undervalued in inquiry media studies that often centre the journalists’ role in uncovering and publicly revealing previously unheard stories. Drawing on international comparisons we find that while quiet listening risks negating the opportunity to amplify experience, it may also counter the potential silencing effects of unwanted public media scrutiny and protect potential witnesses from further harm.

Overview of the Treatment Goal, the Method of Evaluating Disease Activity/Physical Function, Activities of Daily Living, and Traditional Care for Systemic or Articular Juvenile Idiopathic Arthritis in Japan.

Juvenile idiopathic arthritis (JIA) is a chronic arthritis of unknown cause that develops in patients younger than 16 years of age and persists for at least 6 weeks. It is an important cause of short- and long-term physical and mental impairments in children. The goal of treatment for JIA is remission. A T2T (treatment-to-target) has been proposed and practiced as a means of achieving remission. The method of evaluating the disease activity of JIA depends on the disease type. For systemic JIA, disease activity is determined by comprehensively considering joint findings, systemic inflammatory findings, changes in inflammatory and synovitis markers, imaging findings, and other factors. For articular JIA other than systemic JIA, the Juvenile Arthritis Disease Activity Score (JADAS-27) is used to evaluate disease activity. The CHAQ (Childhood Health Assessment Questionnaire) and the Japanese version of the modified Rankin Scale (mRS) are mainly used to assess the physical function and ADL. The CHAQ is a global standard assessment method with the advantage that it can be transitioned to the HAQ used in adults, making it useful for international comparisons. The mRS is used to classify the severity of JIA as a chronic disease, and is an indispensable evaluation method in the specific disease procedure in Japan. It is necessary to have pediatric-specific knowledge of growth and development and routine childhood immunizations and to consider transition support tailored to the patient's situation. Ultimately, the goal is to foster the patient's independence and to provide an uninterrupted follow-up in the adult care department. Continuous follow-up will be provided during the schooling (and later, employment) period, and the relationship with the patient will be tailored to their developmental stage. It is also important to understand and communicate the importance of contraception and the drugs that cannot be used during pregnancy.

Assessing health-related quality of life using the Wound-QoL-17 and the Wound-QoL-14-Results of the cross-sectional European HAQOL study using item response theory.

For assessing health-related quality of life in patients with chronic wounds, the Wound-QoL questionnaire has been developed. Two different versions exist: the Wound-QoL-17 and the Wound-QoL-14. For international and cross-cultural comparisons, it is necessary to demonstrate psychometric properties in an international study. Therefore, the aim of this study was to test both questionnaires in a European sample, using item response theory (IRT). Participants were recruited in eight European countries. Item characteristic curves (ICC), item information curves (IIC) and differential item functioning (DIF) were calculated. In both questionnaires, ICCs for most items were well-ordered and sufficiently distinct. For items, in which adjacent response categories were not sufficiently distinct, response options were merged. IICs showed that items on sleep and on pain, on worries as well as on day-to-day and leisure activities had considerably high informational value. In the Wound-QoL-14, the item on social activities showed DIFs regarding the country and age. The same applied for the Wound-QoL-17, in which also the item on stairs showed DIFs regarding age. Our study showed comparable results across both versions of the Wound-QoL. We established a new scoring method, which could be applied in international research projects. For clinical practice, the original scoring can be maintained.

Saving resources without sacrificing results: an empirical investigation of the dishwashing reality of British consumers in an international comparison

Abstract Routine household tasks, such as laundry or dishwashing, are complex socio-technical systems in which a variety of factors and actors interact, including manufacturers, technologies, regulators, consumer practices, cultural norms and infrastructures. A deep understanding of these socio-technical systems is necessary to find the right recommendations on how to optimise this system in order to achieve relevant savings in resource consumption without requiring a complete renewal of the infrastructure installed. In our case, we focus on automatic dishwashing in the United Kingdom and try to find out what an optimised consumer use of the dishwashers installed can look like and how many savings can be achieved. Accordingly, we modelled the base of dishwashers installed and conducted a consumer survey on dishwasher usage behaviour in sufficient detail to understand the interplay between the various factors. By simulating a change in usage behaviour, we find a potential energy saving of 21.3 % simply by following basic rules for selecting the appropriate programmes without the risk of a loss of performance.

Comparison of factors associated with the evidence-practice gap as perceived by Japanese and Brazilian dentists

ObjectivesTo identify 1) factors of the evidence-practice gap (EPG) in Japan and Brazil as perceived by dentists and compare these factors between two countries, and 2) mechanisms to close this EPG. MethodsThe study employed a cross-sectional design by administering a web-based questionnaire to 136 Japanese and 110 Brazilian dentists. The survey queried dentists’ reports of which factors possibly cause an EPG, using a newly developed 20-item questionnaire. ResultsAn international comparison of 20 items related to factors of the EPG between Japan and Brazil revealed that "Dentists' own experiences are sometimes given priority over evidence" and "Dentists' own thoughts are sometimes given priority over evidence" were common factors to both countries, with over 80 % agreement. In logistic regression, "Insufficient opportunity to learn about evidence in dental education at universities", "Evidence-based treatments are sometimes not covered by the dental insurance system", and "Insufficient evidence which helps dentists choose an appropriate treatment for a patient after careful consideration of his/her own background" were significantly associated with the EPG in Japan (p < 0.05). In Brazil, "Insufficient case reports in which evidence-based dentistry (EBD) is applied to clinical practice" and "Image-based information and devices used for diagnosis vary depending on individual dentists" were significantly associated with the EPG (p < 0.05). ConclusionsThis study suggests that EPG could be improved in Japan: by promoting EBD education at universities, improving the dental insurance system, and accumulating evidence according to patient background; and in Brazil: by promoting EBD case reports and standardizing diagnostic information and devices. Clinical SignificanceTwo factors of EPG common to Japan and Brazil, namely the prioritization of dentists' own "experiences" and "thoughts" over evidence, are urgent issues for improving EPG. In addition, it will be necessary to address the country-specific factors of EPG that were identified in this study.

Translation and cross-cultural adaptation of the Chinese version of the HLS-EU-Q47.

The development of health literacy in China is relatively slow, and there are fewer health literacy scales, which is difficult to measure. Therefore, this study aims to promote the development of health literacy in China through the translation and application of the European Health Literacy Survey Questionnaire (HLS-EU-Q47). The scale was translated into Chinese, back-translated, culturally adapted and finally subjected to psychometric evaluation. A multi-stage stratified sampling method was used to select 2504 residents to test the reliability and validity of a questionnaire on health literacy. Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were used to evaluate the validity of the results, and the back consistency was calculated by Cronbach's alpha coefficient. The EFA revealed that health care, disease prevention and health promotion explained 78.68% of the total variance in health literacy. The scale and its subscales demonstrated strong internal consistency, with high Cronbach's alpha coefficients ranging from 0.947 to 0.983. CFA confirmed the three-factor model's goodness-of-fit for the Chinese population. The dimensions of healthcare, disease prevention and health promotion showed high convergent validity with an average variance extracted values ranging from 0.52 to 0.60 and composite reliability values ranging from 0.94 to 0.96. The reliable and valid Chinese version of the HLS-EU-Q47 (HLS19-Q47-CN) developed and evaluated in this study is an important tool for assessing health literacy levels in the Chinese population. Furthermore, as this tool has global applicability, it has the potential to assess health literacy levels across different countries, enabling practical international comparisons.

Cross-sectional Average Length of Life Entropy (HCAL\\documentclass[12pt]{minimal} \\usepackage{amsmath} \\usepackage{wasysym} \\usepackage{amsfonts} \\usepackage{amssymb} \\usepackage{amsbsy} \\usepackage{mathrsfs} \\usepackage{upgreek} \\setlength{\\oddsidemargin}{-69pt} \\begin{document}$${\\mathcal{H}}_{\ ext{CAL}}$$\\end{document}): International Comparisons and Decompositions

Keyfitz and Leser’s life table entropy was proposed to serve as a relative inequality in mortality measure. Entropy considers the variation around the age at death relative to the length of lifespan in a population, allowing comparisons across time and populations. It is used widely in period and cohort applications. Here, we propose extending this measure and present an index that incorporates the history of survival of all cohorts present at a given time, namely the cross-sectional average length of life entropy, or CAL-entropy (HCAL\\documentclass[12pt]{minimal} \\usepackage{amsmath} \\usepackage{wasysym} \\usepackage{amsfonts} \\usepackage{amssymb} \\usepackage{amsbsy} \\usepackage{mathrsfs} \\usepackage{upgreek} \\setlength{\\oddsidemargin}{-69pt} \\begin{document}$${\\mathcal{H}}_{\ ext{CAL}}$$\\end{document}). We decompose cross-population differences of CAL-entropy into the contribution of longevity and lifespan variation, and the change of those differences across time. Our illustrations show that populations are converging regarding lifespan inequality. Lifespan variation holds a noticeable share in the CAL-entropy gap among selected European populations. Longevity held once a pronounced share in CAL-entropy differences and their change, but its influence has receded over the years. The US demonstrates a unique trend where it performs worse across time compared to the selected European populations, and lifespan variation has played a major role in this process. This study signals the importance of lifespan variation in reducing inequality in mortality among developed and longevous populations.

Cardiac Arrest and Cardiopulmonary Resuscitation Outcome Reports: 2024 Update of the Utstein Out-of-Hospital Cardiac Arrest Registry Template.

The Utstein Out-of-Hospital Cardiac Arrest Resuscitation Registry Template, introduced in 1991 and updated in 2004 and 2015, standardizes data collection to enable research, evaluation, and comparisons of systems of care. The impetus for the current update stemmed from significant advances in the field and insights from registry development and regional comparisons. This 2024 update involved representatives of the International Liaison Committee on Resuscitation and used a modified Delphi process. Every 2015 Utstein data element was reviewed for relevance, priority (core or supplemental), and improvement. New variables were proposed and refined. All changes were voted on for inclusion. The 2015 domains-system, dispatch, patient, process, and outcomes-were retained. Further clarity is provided for the definitions of out-of-hospital cardiac arrest attended resuscitation and attempted resuscitation. Changes reflect advancements in dispatch, early response systems, and resuscitation care, as well as the importance of prehospital outcomes. Time intervals such as emergency medical service response time now emphasize precise reporting of the times used. New flowcharts aid the reporting of system effectiveness for patients with an attempted resuscitation and system efficacy for the Utstein comparator group. Recognizing the varying capacities of emergency systems globally, the writing group provided a minimal dataset for settings with developing emergency medical systems. Supplementary variables are considered useful for research purposes. These revisions aim to elevate data collection and reporting transparency by registries and researchers and to advance international comparisons and collaborations. The overarching objective remains the improvement of outcomes for patients with out-of-hospital cardiac arrest.

A text-mining analysis of Latin America Universities’ mission statements from a ‘Third Mission’ perspective

ABSTRACT University Mission Statements (UMS) were born by imitating a common practice in the business world, where private organisations state their core values and main purposes. Recently, there has been growing interest in analysing UMS through the lens of the Third Mission (TM) of universities. Despite the increasing attention to UMS analysis of TM at the national level, there remains a dearth of research that conducts international comparisons of UMS across various countries utilizing a TM perspective. In this study, we adopt a text mining approach commonly employed in Natural Language Processing studies to categorize 1304 UMS from 19 Latin American countries based on generalized social and economic orientations of TM. By eschewing classifications reliant on specific TM aspects and activities, our analysis aims to facilitate meaningful regional and cross-country comparisons. On average, the orientation of UMS from Latin American countries is 82% social and 55% economic, significant variations observed across countries reflecting the particularities of each Higher Education System. Our results are comparable to previous research analysing single-country UMS, utilizing interpretive content analysis and a Third Mission lens. This evidence offers a quantitative perspective that aligns with existing regional narratives, enriching our understanding of the Third Mission across Latin America.
