ECO²SCAPE Social Network Analysis
No full textWe collected these data within the research project ECO²SCAPE, a transdisciplinary project within the Research Initiative for the Conservation of Biodiversity (FEdA), funded by the German Federal Ministry of Education and Research (BMBF). The purpose for the collection of these data was a social network analysis among farmers in northwest Saxony, Germany. Our aim was to elucidate with whom farmers exchange knowledge on topics related to biodiversity conservation and knowledge on topics related to agricultural production. We also wanted to know from whom farmers receive support for achieving their agricultural goals and their biodiversity conservation goals. Finally, we aimed to understand how the farmers’ social networks influence their participation in agri-environmental schemes. Specifically, we tested two main hypotheses with these data: • Farmers’ social networks related to biodiversity conservation are distinct from those related to agricultural production. • Farmers’ level of participating in AES is associated with their relations to certain actor groups. The corresponding results are described in a paper with the title “Social network analysis among German farmers reveals potentials to overcome the production-conservation dichotomy in land use” that has been accepted for publication in People and Nature. The data comprise three data frames, one including the various farmer attributes (FarmerAttributes.rds), one describing with whom farmers exchange knowledge and by whom they feel supported (NetworkData.rds), and one that assigns each of the 145 actors involved in the network to one of four actor groups (ActorGroups.rds).We collected these data within the research project ECO²SCAPE, a transdisciplinary project within the Research Initiative for the Conservation of Biodiversity (FEdA), funded by the German Federal Ministry of Education and Research (BMBF).

BioMentalitäten 2022
No full textDiese repräsentativen Daten einer Bevölkerungsbefragung sind im Rahmen der Arbeiten der Nachwuchsgruppe "Mentalitäten im Fluss. Vorstellungswelten in modernen bio-kreislaufbasierten Gesellschaften (flumen)" erhoben worden. Das Projekt untersuchte von 2019 bis 2025 wie sich die Grundhaltungen, Einstellungen und gemeinsamen Vorstellungswelten von Menschen verändern, wenn sich die Rohstoff- und Energiebasis der Gesellschaft, in der sie leben, weg von fossilen und hin zu bio-basierten Grundstoffen verschiebt. Bio-basierte Kreislaufwirtschaften, so die zentrale Annahme, verlangen und bedingen andere Formen von Zeit- und Zukunftsbewusstsein, Selbst- und Weltverhältnissen, kurz: andere Mentalitäten als fossile Durchflusswirtschaften. Um diese Mentalitäten zu erfassen, ihre Prägung durch die soziale Position und ihre Zusammenhänge mit Lebensweisen zu untersuchen, enthält die Umfrage drei Themenblöcke: 1. Einstellungen zu allgemeinen sozialen und ökologischen Themen, 2. ausgewählte Alltagspraktiken, aus denen sich auch ein einfacher Co2-Fußabdruck berechnen lässt, sowie 3. eine Vielzahl von sozio-demografischen Merkmalen, welche die Operationalisierung von ökonomischem und kulturellem Kapital und somit die Konstruktion eines differenzierten sozialen Raumes nach Bourdieu erlauben. Zusätzlich wurden Fragen zur Bioökonomie gestellt wie z.B. zur Biolandwirtschaft, Gentechnik und zur Ersetzung von Plastik durch erneuerbare Rohstoffe. Die Daten enthalten auch einige Fragen zur politischen Situation 2021/2022 im Umfeld der Bundestagswahl, aus der die Ampelregierung hervorging, und zur Corona Pandemie, so z.B. zur Akzeptanz von Masken und zu Impfungen. Die Umfrage wurde telefonisch (n=2000) und online (n=2000) für ganz Deutschland durchgeführt sowie im Frühjahr 2022 postalisch nur für Einwohner:innen von Bioenergiedörfern (n=523).Diese repräsentativen Daten einer Bevölkerungsbefragung sind im Rahmen der Arbeiten der Nachwuchsgruppe "Mentalitäten im Fluss.

Conversations of Democracy - Reduced Version
No full textThe MZES project ‘Conversations of Democracy’ (CoDem) addresses a major gap in the empirical study of deliberative politics. Although democratic theory´s deliberative turn stimulated increasing interest in the role of talk for the quality of democratic politics, research has paid hardly any attention to ordinary citizens’ informal conversations about politics so far. No assured knowledge exists about how this form of political communication stands up to the high normative standards of deliberation. Likewise, there is no robust evidence on the factors that lead to a higher deliberative quality of everyday political talk, nor on whether everyday political talk actually entails the beneficial influences on the democratic process expected by deliberative theory. By investigating the deliberativeness as well as the conditions and consequences of everyday political talk, the project seeks to contribute to a deeper understanding of people´s conversations about public affairs as the most basic form of political communication and foundation of democracy’s deliberative system. The methodological core of the project is a face-to-face survey of voters that was conducted during the run-up to the 2017 German federal election in the city of Mannheim. Two further design components are derivatives from this baseline survey: re-interviews of the same respondents in a second panel wave conducted via telephone several months after the election, and follow-up telephone or Web interviews with individuals whom the respondents named as their most important political discussion partners during the main interviews.Das MZES-Projekt „Conversations of Democracy” (CoDem) befasst sich mit einer großen Lücke in der empirischen Erforschung der deliberativen Politik. Obwohl die deliberative Wende in der Demokratietheorie das Interesse an der Rolle des Gesprächs für die Qualität der demokratischen Politik geweckt hat, hat die Forschung den informellen Gesprächen gewöhnlicher Bürger über Politik bisher kaum Beachtung geschenkt. Es gibt keine gesicherten Erkenntnisse darüber, inwieweit diese Form der politischen Kommunikation den hohen normativen Standards der Deliberation gerecht wird. Ebenso wenig gibt es belastbare Erkenntnisse darüber, welche Faktoren zu einer höheren deliberativen Qualität alltäglicher politischer Gespräche führen und ob diese tatsächlich die von der Deliberationstheorie erwarteten positiven Auswirkungen auf den demokratischen Prozess haben. Durch die Untersuchung der Deliberativität sowie der Bedingungen und Folgen alltäglicher politischer Gespräche möchte das Projekt zu einem tieferen Verständnis der Gespräche der Menschen über öffentliche Angelegenheiten als grundlegendste Form der politischen Kommunikation und Grundlage des deliberativen Systems der Demokratie beitragen. Der methodische Kern des Projekts ist eine persönliche Befragung von Wählern, die im Vorfeld der Bundestagswahl 2017 in Mannheim durchgeführt wurde. Zwei weitere Komponenten des Designs leiten sich aus dieser Basisbefragung ab: erneute Befragungen derselben Personen in einer zweiten Panelwelle, die einige Monate nach der Wahl telefonisch durchgeführt wurde, sowie Folgebefragungen per Telefon oder Internet mit Personen, die die Befragten in den Hauptbefragungen als ihre wichtigsten politischen Gesprächspartner genannt hatten
Data för: Public preferences on policies for climate, local pollution, and health - a survey in seven large Global South countries
No full textThe current dataset is a subset of a large data collection based on a purpose-built survey conducted in seven middle-income countries in the Global South: Chile, Colombia, India, Kenya, Nigeria, Tanzania, South Africa and Vietnam. The purpose of the collected variables in the present dataset aims to understanding public preferences as a critical way to any effort to reduce greenhouse gas emissions. There are many studies of public preferences regarding climate change in the Global North. However, survey work in low and middle-income countries is limited. Survey work facilitating cross-country comparisons not using the major omnibus surveys is relatively rare. We designed the Environment for Development (EfD) Seven-country Global South Climate Survey (the EfD Survey) which collected information on respondents’ knowledge about climate change, the information sources that respondents rely on, and opinions on climate policy. The EfD survey contains a battery of well-known climate knowledge questions and questions concerning the attention to and degree of trust in various sources for climate information. Respondents faced several ranking tasks using a best-worst elicitation format. This approach offers greater robustness to cultural differences in how questions are answered than the Likert-scale questions commonly asked in omnibus surveys. We examine: (a) priorities for spending in thirteen policy areas including climate and COVID-19, (b) how respiratory diseases due to air pollution rank relative to six other health problems, (c) agreement with ten statements characterizing various aspects of climate policies, and (d) prioritization of uses for carbon tax revenue. The company YouGov collected data for the EfD Survey in 2023 from 8400 respondents, 1200 in each country. It supplements an earlier survey wave (administered a year earlier) that focused on COVID-19. Respondents were drawn from YouGov’s online panels. During the COVID-19 pandemic almost all surveys were conducted online. This has advantages and disadvantages. Online survey administration reduces costs and data collection times and allows for experimental designs assigning different survey stimuli. With substantial incentive payments, high response rates within the sampling frame are achievable and such incentivized respondents are hopefully motivated to carefully answer the questions posed. The main disadvantage is that the sampling frame is comprised of the internet-enabled portion of the population in each country (e.g., with computers, mobile phones, and tablets). This sample systematically underrepresents those with lower incomes and living in rural areas. This large segment of the population is, however, of considerable interest in its own right due to its exposure to online media and outsized influence on public opinion. The data includes respondents’ preferences for climate change mitigation policies and competing policy issues like health. The data also includes questions such as how respondents think revenues from carbon taxes should be used. The outcome provide important information for policymakers to understand, evaluate, and shape national climate policies. It is worth noting that the data from Tanzania is only present in Wave 1 and that the data from Chile is only present in Wave 2.The current dataset is a subset of a large data collection based on a purpose-built survey conducted in seven middle-income countries in the Global South: Chile, Colombia, India, Kenya, Nigeria, Tanzania, South Africa and Vietnam.

Growing Up in Ireland (GUI) Cohort ’98 (Child Cohort) Wave 5 - 25 years, 2023
No full textGrowing Up in Ireland - the National Longitudinal Study of Children is a landmark study of children and youth which has been running since 2006. The objectives of the study are outlined in a separate publication (Greene et al. 2010). In summary the project seeks to further our understanding of what it means to be a child or young person growing up in modern Ireland, with a view to informing policy on what both helps and hinders development. A two cohort, cross-sequential longitudinal design was adopted and began with one cohort (Cohort 08) of 11,134 infants (aged 9 months) and a second cohort (Cohort 98) of 8,568 9-year-olds. A third cohort (Cohort 24) will follow infants from age 9 months. Being longitudinal in nature, the same children are followed over time. The families of Cohort 08 have been interviewed when the children were 9 months, 3 years, 5 years, 7/8 years, 9 years and subsequently at 13 years of age, while Cohort 98 and their parents/guardians were interviewed at 9, 13, 17/18 and 20 years of age. This dataset relates to Wave 5 of Cohort 98 when respondents were 25 years old

The families of the Infant Cohort have been interviewed when the children were 9 months, 3 years and subsequently 5 years of age, while the Child Cohort and their parents/guardians were interviewed at 9, 13 and 17/18 years of age. This wave of data concerns a postal survey of the Primary Caregivers of the children in the Infant Cohort when those children were 7/8 years old
Economic Redistribution Preferences in the Food Supply Chain
No full textThis dataset originates from a cross-national survey on public perceptions of income distribution in the food supply chain, conducted in Germany (n = 1,495) and the United States (n = 1,190) in February 2025. The study investigates how citizens evaluate the fairness of transactions between supply chain actors, their preferences for redistributing value among these actors, and their willingness to support and pay for interventions aimed at improving farmers' positions. Respondents assessed four stylized transactions covering the full supply chain (from input providers to consumers), and completed scenario-based measures of fairness, power, and valuation principles (e.g., labor vs. market-based pricing). The survey also captured support for public regulation (price floors) and private initiatives (labeling schemes), alongside attitudinal variables such as views on markets, middlemen, and agricultural policy. The dataset enables analysis of economic fairness perceptions, food system governance preferences, and behavioral responses to redistributive scenarios. It supports research in behavioral economics, agricultural and food policy, economic sociology, and political economy.This dataset originates from a cross-national survey on public perceptions of income distribution in the food supply chain, conducted in Germany (n = 1,495) and the United States (n = 1,190) in February 2025.

Replication data and code: Invitation Messages for Business Surveys: A Multi-Armed Bandit Experiment
No full textThis replication package contains the experimental data and code from a study investigating how elements of a survey invitation message targeted to businesses influence their participation in a self-administered web survey. The experiment was conducted in collaboration with the German Business Panel (GBP) during its fifth survey wave, spanning from August 16, 2022, to November 25, 2022. A full factorial design was implemented, varying five key components of the email invitation. Unlike conventional experimental setups with static group assignments, the study employed adaptive randomization, wherein a Bayesian learning algorithm sequentially allocated more observations to invitation messages exhibiting higher survey starting rates. Over the 15-week experimental period, 738,598 invitation messages were distributed to business contacts, of which 176,000 were opened within one week. A total of 7,833 recipients initiated the survey, and 3,733 completed it. The dataset includes detailed records of message distribution, survey engagement metrics, and adaptive randomization adjustments, providing a comprehensive basis for analyzing the effectiveness of invitation design in business survey participation.
