TY - INPR A1 - Kohler, Ulrich T1 - Maintaining quality T2 - Survey research methods N2 - Survey Research Methods has slightly revised its publication policies. Firstly, starting with the publication of this Editorial, SRM will accept - under specified conditions - manuscripts that discuss experiments in non-probability samples for peer-review. Secondly, SRM will require authors to publish replication materials of their study as Online supplement to their article. Finally, Survey Research Methods will publish replication studies of articles published in the journal. This Editorial gives reasons for these changes.

Nevertheless, there has been insufficient progress in measuring PI. We calculate a novel measure of PI with the German Socio-Economic Panel (SOEP) and U.S. Panel Study of Income Dynamics (PSID). Advancing beyond prior approaches, we define PI as the logged average of 20+ years of post-tax and post-transfer ("post-fisc") real equivalized household income. We then assess how well various household- and individual-based measures of economic resources proxy PI. In both datasets, post-fisc household income is the best proxy. One random year of post-fisc household income explains about half of the variation in PI, and 2-5 years explain the vast majority of the variation. One year of post-fisc HH income even predicts PI better than 20+ years of individual labor market earnings or long-term net worth. By contrast, earnings, wealth, occupation, and class are weaker and less cross-nationally reliable proxies for PI. We also present strategies for proxying PI when HH post-fisc income data are unavailable, and show how post-fisc HH income proxies PI over the life cycle. In sum, we develop a novel approach to PI, systematically assess proxies for PI, and inform the measurement of economic resources more generally.

T1 - Nonprobability Sampling and Causal Analysis JF - Annual review of statistics and its application N2 - The long-standing approach of using probability samples in social science research has come under pressure through eroding survey response rates, advanced methodology, and easier access to large amounts of data. These factors, along with an increased awareness of the pitfalls of the nonequivalent comparison group design for the estimation of causal effects, have moved the attention of applied researchers away from issues of sampling and toward issues of identification. This article discusses the usability of samples with unknown selection probabilities for various research questions. In doing so, we review assumptions necessary for descriptive and causal inference and discuss research strategies developed to overcome sampling limitations.

Mehrere Studien haben zudem gezeigt, dass Lateinkenntnisse weder das logische Denken, noch den Erwerb anderer Sprachen, noch das Gespür für die grammatikalische Struktur der Muttersprache verbessern. Auch wenn sich empirisch keine Vorteile des Erwerbs alter Sprachen nachweisen lassen, können Menschen subjektiv an solche Vorteile glauben und ihr Verhalten an ihrer Konstruktion von Wirklichkeit ausrichten. Auf der Basis einer unter Eltern von Gymnasialschülern durchgeführten Befragung zeigen wir, dass Latein umfassende Transfereffekte zugeschrieben und Personen mit Lateinkenntnissen positiver bewertet werden als Personen mit Kenntnissen moderner Sprachen. Weiterhin zeigt sich, dass die „Illusio“ der Vorteile von Latein zwar in allen Bildungsgruppen wirksam ist, doch besonders von den Hochgebildeten vertreten wird. Sie arbeiten damit an der Konstruktion einer Realität, von der sie selbst die größten Nutznießer sind, indem sie Latein als symbolisches Kapital verwenden. N2 - Although Latin is a non-spoken language and therefore has no communicative value, the number of students choosing Latin as a foreign language at school has increased over time. Several studies have shown that learning Latin does neither improve logical thinking, nor the acquisition of other foreign languages, nor linguistic abilities in the mother tongue. Despite the empirical lack of benefits associated with the acquisition of ancient languages, people might believe in such benefits and behave in accordance with their construction of reality. Based on a survey conducted among parents of students at German high schools ("Gymnasium"), we show that parents extensively attribute transfer effects to learning Latin. Furthermore, people with knowledge of Latin are rated more positively than those with knowledge of modern languages with respect to their general and cultural education, as well as their social status. We also demonstrate that although the illusory of the benefits of Latin is prevalent in all educational groups, it is particularly pronounced among the higher educated. They construct a social reality of which they are the greatest beneficiaries by using Latin as a symbolic capital.

Evidence From Germany's Refugee Allocation Policy JF - Frontiers in Sociology N2 - Emerging evidence has highlighted the important role of local contexts for integration trajectories of asylum seekers and refugees. Germany's policy of randomly allocating asylum seekers across Germany may advantage some and disadvantage others in terms of opportunities for equal participation in society. This study explores the question whether asylum seekers that have been allocated to rural areas experience disadvantages in terms of language acquisition compared to those allocated to urban areas. We derive testable assumptions using a Directed Acyclic Graph (DAG) which are then tested using large-N survey data (IAB-BAMF-SOEP refugee survey). We find that living in a rural area has no negative total effect on language skills. Further the findings suggest that the “null effect” is the result of two processes which offset each other: while asylum seekers in rural areas have slightly lower access for formal, federally organized language courses, they have more regular exposure to German speakers.
