Hierbei sollte eine L{\"u}cke in der deutschen Forschung geschlossen werden, indem neben individuellen Faktoren auch {\"o}kologische Faktoren durch einen Mehrebenenansatz einbezogen wurden. Auf {\"o}kologischer Ebene wurde die Effekte der regionalen sozialen Deprivation, der Urbanisierung und der Arztdichte der ambulanten {\"A}rzte analysiert. Variablen auf Individualebene waren Geschlecht und Gesundheitsstatus. In der Studie wurden drei verschiedene Datenbanken miteinander verkn{\"u}pft. Zur Berechnung der regionalen sozialen Deprivation und der Urbanisierung wurden Daten von INKAR f{\"u}r alle 402 Kreise verwendet. Das Bundesarztregister lieferte die Datengrundlage zur Bestimmung der Arztdichte. Die Abrechnungsdaten aller Kassen{\"a}rztlichen Vereinigungen nach \S 295 SGB V lieferten die Zahlen f{\"u}r die Inanspruchnahme der spezifischen Pr{\"a}ventionsangebote als auch f{\"u}r Geschlecht und Gesundheitsstatus. Hierdurch war es m{\"o}glich eine Vollerhebung aller gesetzlich Krankenversicherten zwischen 50 und 55 Jahren durchzuf{\"u}hren, die 2013 einen Arzt aufgesucht haben (N = 6,6 Mio.). Die unabh{\"a}ngigen Variablen der regionalen sozialen Deprivation und Urbanisierung sowie die Kontrollvariable Gesundheitsstatus wurden mit Hilfe der Faktorenanalyse gebildet. Um die regionalen Unterschiede analysieren zu k{\"o}nnen, wurde eine hierarchische multivariate Regression durchgef{\"u}hrt. Rund 80\% aller sekund{\"a}rpr{\"a}ventiven Leistungen wurden von Frauen in Anspruch genommen. Ein schlechterer Gesundheitsstatus war mit einer h{\"o}heren Rate der Inanspruchnahme assoziiert. Die Ergebnisse weisen auf regionale Unterschiede hin, die sich nach Geschlecht unterscheiden wobei die unabh{\"a}ngigen Variablen nur kleine Effekte aufweisen. Entgegen der Hypothese war eine h{\"o}here regionale soziale Deprivation mit einer h{\"o}heren Inanspruchnahme bei M{\"a}nnern und Frauen assoziiert. Urbanit{\"a}t war bei M{\"a}nnern positiv und bei Frauen negativ mit der Inanspruchnahme assoziiert. Die Interaktion beider Variablen hat keinen Effekt auf M{\"a}nner aber einen negativen Effekt auf Frauen. Die Arztdichte wurde aus dem finalen statistischen Modell ausgeschlossen, da die Variable Multikollinearit{\"a}t aufwies. Bisherige Theorien sind nicht in der Lage die Ergebnisse zu erkl{\"a}ren, da sie bisherigen Forschungsergebnissen widersprechen. Zus{\"a}tzliche Berechnungen legen die Schlussfolgerung nahe, dass die herrschenden Ost-West-Unterschiede zu einer Konfundierung der Ergebnisse gef{\"u}hrt haben. Ber{\"u}cksichtigt man das Alter der Patienten, kann vermutet werden, dass die Sozialisation der Inanspruchnahme sekund{\"a}rpr{\"a}ventiver Leistungen in der DDR bis heute das Gesundheitsverhalten beeinflusst.

Firms from mature industries are increasingly realizing that BMs that worked successfully for years have become insufficient to stay on track in today's "move fast and break things" economy. Firms must scrutinize the core logic that informs how they do business, which means exploring novel ways to engage customers and get them to pay. This can lead to a complete renewal of existing BMs or innovating completely new BMs. BMs have emerged as a popular object of research within the last decade. Despite the popularity of the BM, the theoretical and empirical foundation underlying the concept is still weak. In particular, the innovation process for BMs has been developed and implemented in firms, but understanding of the mechanisms behind it is still lacking. Business model innovation (BMI) is a complex and challenging management task that requires more than just novel ideas. Systematic studies to generate a better understanding of BMI and support incumbents with appropriate concepts to improve BMI development are in short supply. Further, there is a lack of knowledge about appropriate research practices for studying BMI and generating valid data sets in order to meet expectations in both practice and academia. This paper-based dissertation aims to contribute to research practice in the field of BM and BMI and foster better understanding of the BM concept and BMI processes in incumbent firms from mature industries. The overall dissertation presents three main results. The first result is a new perspective, or the systems thinking view, on the BM and BMI. With the systems thinking view, the fuzzy BM concept is clearly structured and a BMI framework is proposed. The second result is a new research strategy for studying BMI. After analyzing current research practice in the areas of BMs and BMI, it is obvious that there is a need for better research on BMs and BMI in terms of accuracy, transparency, and practical orientation. Thus, the action case study approach combined with abductive methodology is proposed and proven in the research setting of this thesis. The third result stems from three action case studies in incumbent firms from mature industries employed to study how BMI occurs in practice. The new insights and knowledge gained from the action case studies help to explain BMI in such industries and increase understanding of the core of these processes. By studying these issues, the articles complied in this thesis contribute conceptually and empirically to the recently consolidated but still increasing literature on the BM and BMI. The conclusions and implications made are intended to foster further research and improve managerial practices for achieving BMI in a dramatically changing business environment.}, language = {en} } @misc{SafaviHusainVasishth2016, author = {Safavi, Molood S. and Husain, Samar and Vasishth, Shravan}, title = {Dependency Resolution Difficulty Increases with Distance in Persian Separable Complex Predicates}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-90728}, pages = {1 -- 15}, year = {2016}, abstract = {Delaying the appearance of a verb in a noun-verb dependency tends to increase processing difficulty at the verb; one explanation for this locality effect is decay and/or interference of the noun in working memory.

However, another expectation-based measure, entropy, which was computed using the offline sentence completion data, predicts reading times in Experiment 1 but not in the other experiments.
