Identifying and explaining inconsistencies in linked administrative and survey data: the case of German employment biographies

'Befragungen ziehen oft bestimmte Probleme nach sich: Erinnerungslücken kommen vor und Befragte erinnern sich nicht mehr an jede Einzelheit. Eine Möglichkeit diese Probleme zu lösen, ist die zusätzliche Nutzung von qualitativen Informationen. Eine weitere, bisher jedoch vernachlässigte Möglichkeit ist die Verwendung von administrativen Daten zur Ergänzung von Befragungsdaten. Der Schwerpunkt dieses Beitrags liegt auf den Potenzialen und Problemen bei der Verknüpfung von administrativen Daten mit Befragungsdaten. Insbesondere soll dies anhand retrospektiv erhobener Berufsbiographien und den entsprechenden administrativen Daten aufgezeigt werden.' (Autorenreferat)'Surveys often cope with special problems: gaps in retrospection appear or respondents could not provide details. Sometimes these problems can be solved by using additional qualitative information. Another - so far disregarded - possibility is to use process-generated data to expand survey data. The focus of this article is on the potentials and problems of linking administrative and survey data. In particular this is shown by comparison of retrospective survey information on employment cycles and the according process-generated data.' (author's abstract

Determining the differential preferences of users of two fluoride-free water options in rural Ethiopia

Aim: In the Ethiopian Rift Valley, 8.5 million people depend on water sources with excessive fluoride. In one rural village, a fluoride-removal community filter was implemented; a personalized reminder was distributed to change people's behavior and increase the usage of the in-village community filter. During this promotion phase, an alternative fluoride-removal option was installed in a neighboring village. This study examines psychological factors that explain the differences in preference between the two options and their influence on the usage of the different sources. In addition, the effectiveness of the applied behavior change technique, a personalized reminder, on the use of the in-village community filter was analyzed. Subject and methods: In a complete longitudinal survey, 180 households, with access to both mitigation options, were interviewed through structured, face-to-face interviews. Logistic regressions were carried out to reveal factors predicting the usage of the two mitigation options and the effect of the implemented behavior change intervention. Results: The results showed that the better the taste, the lower the effort and the lower the costs for using the in-village community filter are perceived; in addition, the lower the perceived vulnerability to contract disease, the more the in-village community filter is used. Moreover, it was found that the personalized reminder also had a positive effect on the usage of the in-village mitigation option. Conclusion: Based on the results, possible recommendations for practitioners and researchers are made to help plan and implement mitigation option

WeLL – Unique Linked Employer-Employee Data on Further Training in Germany

This paper explains the main features of an innovative linked employer-employee data set with a particular focus on continuous training in Germany, calledWeLL. The data set comprises establishment data that can be linked to longitudinal information on the associated employees. The employer survey and the first wave of the employee survey were conducted in 2007. Both surveys focus on the collection of training information together with a variety of employee and employer background characteristics. In addition, it is possible to link these data with other survey and administrative data for a large number of respondents.Employee training, establishment data, linked employer-employee data

Panel "WeLL" : Arbeitnehmerbefragung für das Projekt "Berufliche Weiterbildung als Bestandteil Lebenslangen Lernens". Dokumentation der Wellen 1-2

"The main target of the project 'Further Training as a Part of Lifelong Learning' (Berufliche Weiterbildung als Bestandteil Lebenslangen Lernens - WeLL) is to establish a linked employer- employee data set with the particular focus on continuous training that contains information on training investments of employers and employees. In the first instance the employers were interviewed. Afterwards their employees were surveyed concerning their training activities. This employee survey was designed as panel study conducted in 2007, 2008, 2009. This information is necessary to gain insights into the development of individual training investment in the course of time and differentiating short-run and medium-run training returns. The report contains information on data collection, data editing, anonymisation, data access and first of all the description of the variables of the first and second wave."

Determinants of exclusive consumption of fluoride-free water: a cross-sectional household study in rural Ethiopia

Aim: The occurrence of high fluoride concentrations in the ground- and surface water all over the world leads to the risk of developing dental and skeletal fluorosis. In Ethiopia, 8 million people depend on water sources with excessive fluoride. In four project areas in the Ethiopian Rift Valley, fluoride removal household filters based on bone char media have been implemented. This study examines possible predictors of consuming filtered water derived from various behavior change theories. Subject and methods: In a complete cross-sectional survey, 160 filter users were interviewed through structured face-to-face interviews. A logistic regression was carried out to reveal factors predicting consumption of filtered water. Results: The results show that the consumption of fluoride-free water is mainly related to people's pride in offering filtered water to guests (status norm) and the feeling of being able to produce enough water with the filter (perceived behavioral control). Moreover, the study showed that the more filter users like the taste of filtered water and the more expensive they perceive the filter media, the more likely users will exclusively consume filtered water (attitudinal beliefs). Furthermore, perceiving the act of filling as a matter of habit (perceived habit) enhances filtered water consumption. Conclusion: Based on the results, possible intervention strategies to change the influential psychological factors and, hence, increase the consumption of treated water can be designe

Panel "WeLL" : Arbeitnehmerbefragung für das Projekt "Berufliche Weiterbildung als Bestandteil Lebenslangen Lernens"

"Ziel des Kooperationsprojekts 'Berufliche Weiterbildung als Bestandteil Lebenslangen Lernens' (WeLL) ist die Erstellung eines sogenannten Linked-Employer-Employee-Datensatzes, welcher Informationen zur beruflichen Weiterbildung von Arbeitgebern und Arbeitnehmern enthält. Für das Projekt wurden zunächst Betriebe zu ihrem Weiterbildungsverhalten interviewt. Anschließend wurden deren Beschäftigte zu diesem Thema befragt. Diese Arbeitnehmererhebung ist als Längsschnittbefragung mit drei Befragungszeitpunkten in 2007, 2008 und 2009 angelegt um Veränderungen der individuellen Weiterbildungsaktivitäten beobachten und zwischen kurzfristigen und mittelfristigen Weiterbildungseffekten unterscheiden zu können." Der Report enthält neben Informationen zur Datenbeschreibung, Datenerhebung, Datenaufbereitung, Anonymisierung und Datenzugang vor allem die Beschreibung der Variablen im Organisationsdatensatz, im Weiterbildungsdatensatz, im Querschnittsdatensatz und im Biographiedatensatz.

Undiagnosed Myocardial Tear Blocked byan Omental Plug: Potentially LifethreateningCondition

Blunt chest trauma carries a high mortality when associated with cardiac rupture. Rapid diagnosis represents a true challenge for clinicians, with CT scan examination playing a central role. We report a case of a traumatic myocardial tear, plugged by the greater omentum through a diaphragmatic rent in an hemodynamically stable patient. This condition, identified during laparoscopy, was not suspected preoperatively at both clinical examination and CT. This case illustrates that a transparietal cardiac rupture can be sealed off by surrounding structures. This phenomenon explains why CT can be unable to detect traumatic cardiac rupture, with the potential risk of a delayed fatal bleeding. This case also emphasizes the risk of using laparoscopy in traumatic diaphragm rupture repai
