  abstract  = {Rund 20 Jahre nach dem Ende der Sowjetunion verharrt ein Großteil l{\"a}ndlich gepr{\"a}gter Regionen in der Russl{\"a}ndischen F{\"o}deration in einer strukturellen Krise, die sich auf {\"o}konomischer, sozialer und politischer Ebene niederschl{\"a}gt. Auch wenn sich l{\"a}ndliche R{\"a}ume als vermeintliche Verlierer der Transformation erwiesen haben, so sind sie doch vielfach in sich differenziert und zeigen verschiedenartige Problemlagen und Entwicklungspfade auf, die vom Umgang mit den Herausforderungen des Systemwechsels zeugen. Beispielhaft wird dies am Deutschen Nationalen Rayon Altai (DNR Altai) dargestellt, dessen Transformationsphase in der vorliegenden Arbeit rekonstruiert wird. Der DNR Altai stellt in vielerlei Hinsicht einen Sonderfall dar, da er als r{\"a}umlicher Fixpunkt russlanddeutscher Entwicklungspolitik in die bundesdeutsche F{\"o}rderkulisse eingebettet war. Mit dem allm{\"a}hlichen R{\"u}ckzug der deutschen F{\"o}rderinstitutionen stellt sich jedoch die Frage nach nachhaltigen Strukturen, Verstetigung von Projekten und der Zukunft russlanddeutscher Kultur im Altai.},

  abstract  = {Business process models are used within a range of organizational initiatives, where every stakeholder has a unique perspective on a process and demands the respective model. As a consequence, multiple process models capturing the very same business process coexist. Keeping such models in sync is a challenge within an ever changing business environment: once a process is changed, all its models have to be updated. Due to a large number of models and their complex relations, model maintenance becomes error-prone and expensive. Against this background, business process model abstraction emerged as an operation reducing the number of stored process models and facilitating model management. Business process model abstraction is an operation preserving essential process properties and leaving out insignificant details in order to retain information relevant for a particular purpose. Process model abstraction has been addressed by several researchers. The focus of their studies has been on particular use cases and model transformations supporting these use cases. This thesis systematically approaches the problem of business process model abstraction shaping the outcome into a framework. We investigate the current industry demand in abstraction summarizing it in a catalog of business process model abstraction use cases. The thesis focuses on one prominent use case where the user demands a model with coarse-grained activities and overall process ordering constraints. We develop model transformations that support this use case starting with the transformations based on process model structure analysis. Further, abstraction methods considering the semantics of process model elements are investigated. First, we suggest how semantically related activities can be discovered in process models-a barely researched challenge. The thesis validates the designed abstraction methods against sets of industrial process models and discusses the method implementation aspects. Second, we develop a novel model transformation, which combined with the related activity discovery allows flexible non-hierarchical abstraction. In this way this thesis advocates novel model transformations that facilitate business process model management and provides the foundations for innovative tool support.},
