Die Methodenentwicklung zum Umgang mit Veränderungen ist eines der wesentlichen Forschungsfelder der Fabrikplanung. Fehlende Klarheit im Begriffskanon der Veränderungsfähigkeit erschwert die Entwicklung von stringenten Gestaltungsansätzen für Fabriksysteme. Um dies zu verbessern, teilt der Beitrag Veränderungen hinsichtlich des Nachfrageverlaufs in drei Kategorien ein. Jeder Kategorie ist eine Klasse der Veränderungsfähigkeit mit der resultierenden Fabrikeigenschaft zugeordnet. Für die Fabrikplanung ergeben sich daraus je Klasse vier ‚Befähiger‘, die sich zudem in einem Lösungsprinzip zusammenfassen lassen.

The collection of longitudinal data is crucial in some domains such as life course studies. However, prospective studies are considerably costly, and thus retrospective data are an appealing alternative. A life history calendar is a tool specifically conceived to collect retrospective data. However, although it is designed to enhance the recall process of the respondents, the accuracy of the data collected through this approach remains unknown, particularly when data is collected online. In this study, we conducted a secondary analysis of data collected from n = 5,181 respondents through an online survey regarding their sexual health. Because we inquired about the occurrence of certain events twice during the survey, once using a life calendar and once through a traditional questionnaire, we were able to perform three types of consistency checks: (1) reporting of single events, (2) age when the events occurred and (3) correct timing between two events. The main results indicated that it is generally more difficult to remember the exact age of occurrence of an event than the event itself, that the report of related events is generally coherent, and that women are generally more accurate in their answers than men. Based on our results, it is therefore possible to identify a subset of persons whose answers are more consistent throughout the survey. This study also shows that data obtained through an online life history calendar can be of a quality similar to that obtained through a traditional online questionnaire.

To assert the quality of retrospective data, most studies using tools such as life history calendars rely on comparisons with external sources. Our research aimed to integrate quality principles into a life history calendar and test their capacity to evaluate the data quality. The purpose was to avoid reliance on external data sources because of their possible unavailability. The first quality principle was the relationship between the dating accuracy of verifiable events and the data quality of the life domains of the calendar. The second was the certainty, as self-assessed by participants through color coding, that an event took place at the quarter indicated. We designed an experiment using a paper-and-pencil life history calendar that was completed by 104 university students. Our research highlighted the relevance to use the self-assessment of certainty to assert the data quality. However, we could not establish a relationship between the dating accuracy of verifiable events and the data quality of the life domains. In addition, we present a set of qualitative findings from 20 interviews conducted with study participants explaining the approaches used to complete a life calendar and the difficulties encountered.The online version contains supplementary material available at 10.1007/s11135-022-01563-x.

Introduction:Participation outside home has recently been given attention with a focus on places visited for persons living with and without dementia. Multiple factors like socio-demographic aspects and risk perception have been shown to influence the perception of participation outside home.Aim and methods:This cross-sectional, explorative study aims to explore how places visited, socio-demographic aspects and risk perception are associated with the perception of participation outside home for a sample of 70 persons living with and without dementia in Switzerland. First, we investigated whether the number of places visited was correlated with the perception of participation outside home; then we added socio-demographic and risk perception factors with a bivariate analysis; and searched for a model using multinomial logistic regressions.Results:The number of places visited was associated with the perception of participation outside home, but only for the group of persons living without dementia (p = .043). Risks of falling (p=.014) and of getting lost (p=.037) were associated for the group of persons living with dementia only. Being able to visit places for recreational and physical activities (p=.005) was associated for the group of persons living without dementia. Discussion and conclusion:The results of the exploration of multiple factors and search for a model, highlights the complexity of participation outside home as a construct. Visiting multiple and various types of places seem to play a role in participation outside home but would need to be further investigated.

This study is based on two waves of data collected by the Swiss Household panel, the first one in 2019, before the beginning of the COVID-19 pandemic, and the second one in May–June 2020, just after the end of the partial lockdown that was decided by the Swiss government. We considered “couples” of adolescents (age 14–24, mean = 18.82, 51.96% female) and their parents living together (n = 431). Our main goal was to determine whether the evolution of the well-being among adolescents was similar to the evolution of the well-being among parents. Ten indicators of well-being were measured identically in both waves and for both adolescents and their parents. Results indicate that while almost all indicators of well-being decreased during partial lockdown for both adolescents and their parents, adolescents were more strongly impacted than their parents. Furthermore, the change observed in adolescents was virtually unaffected by the change observed in their parents, and vice versa. This research is a reminder that while different population groups may be affected differently by a sudden and extreme event, it is not only older people who will be most affected. Here, adolescents appear to have been more adversely affected than adults.
