To corroborate this claim, I reconstruct two lines of argument that have dominated the discourse on the organizational nature of the German university so far. This discourse has only started in the late 1980s and early 1990s in the wake of new public management emphasizing that the reform of higher education governance has turned German universities into corporate actors (Meier 2009; Krücken and Meier 2006). At the same time, voices have risen advocating the singularity of the university and contrasting it to bureaucratic and corporate forms of organization. The paper starts by outlining these two strands of argumentation: the first highlights the organizational normality of the German university, the next its singularity. Against this background, I shall argue that both positions can be integrated if we rely on the term ``multiple hybrid organization.'' This concept is integrated into the systems theory concept of formal organization which serves as a theoretical means for analyzing organizations at large. The new concept of multiple organizational hybridity demonstrates its usefulness in showing that the structural particularity of the German university is rooted in numerous frictions pertaining to all its organizational structures.", "issn" : "1573-174X", "doi" : "10.1007/s10734-018-0321-7", "bibtexKey": "Kleimann2019" } , { "type" : "Publication", "id" : "https://puma.ub.uni-stuttgart.de/bibtex/2736a9c78ce1af31b42c0593dbd0697a6/droessler", "tags" : [ "bundesländer","deutschland","föderalismus","politik","politisches","system" ], "intraHash" : "736a9c78ce1af31b42c0593dbd0697a6", "interHash" : "b1247284153d8eaaa3cccd32e4c4632c", "label" : "Die Politik der Bundesländer.

In this paper, we summarize and extend our work on different aspects of this branch of Web 2.0 research, demonstrated and evaluated within our own social bookmark and publication sharing system BibSonomy, which is currently among the three most popular systems of its kind. We structure this presentation along the different interaction phases of a user with our system, coupling the relevant research questions of each phase with the corresponding implementation issues. This approach reveals in a systematic fashion important aspects and results of the broad bandwidth of folksonomy research like capturing of emergent semantics, spam detection, ranking algorithms, analogies to search engine log data, personalized tag recommendations and information extraction techniques.

They are intelligent devices that assist their users in operating them: instead of the user having to learn how to operate the respective system, the system is intelligent and flexible enough to provide its functionality in a truly user-friendly way. To fully meet a user's demands, Companion Systems rely on a multi-facet of capabilities that stem from different disciplines, such as Artificial Intelligence (AI) planning, knowledge representation and reasoning, dialog management, and user interaction management, to name just a few. This thesis focuses on the relevant aspects of AI planning technology that are of importance for such systems. AI planning is the central technology for many Companion Systems as it allows to compute a course of action that, if followed by its user, achieves his or her goals and therefore serves as a basis of providing advanced user assistance. This thesis is concerned with hybrid planning - a hierarchical planning formalism that is especially suited for the basis of providing assistance to human users. Based on this formalism we will investigate the full endeavor of developing Companion Systems - from theory to practice. The thesis presents a novel formalization for hierarchical planning problems, which has become a standard in the field. We present a categorization of different problem classes into which hybrid planning as well as other well-known problem classes fall. This formalization allowed to prove a series of novel complexity results that are of interest both for theoretical and practical considerations. For many of the identified classes we introduce novel heuristics that are used to speed up the solution generation process. Some of them are the very first for the respective problem class, and some are the first admissible ones, thereby allowing to find optimal solutions -- which is especially important when plans are generated for human users. We apply hybrid planning in a prototypical Companion System. It assists a user in the task of setting up a complex home entertainment system. Based on a declarative (planning) model of the available hardware and its functionality, the assistant computes a sequence of actions that the user simply needs to follow to complete the setup task. Several so-called user-centered planning capabilities are applied in this system, such as a technique for generating user-friendly linearizations of non-linear plans or the capability to answer questions about the necessity of actions - an essential property to ensure transparency of the system's behavior. In conclusion: Most modern technical devices are still lacking true intelligence - since no research such as AI planning is sufficiently applied, so there is still huge potential in making such devices really smart by implementing them as cognitive systems that effectively assist their human users. Applying the research presented in this thesis is one step towards achieving this goal.", "id" : "https://oparu.uni-ulm.de/xmlui/handle/123456789/5299, http://dx.doi.org/10.18725/OPARU-5242, 1658644298, https://oparu.uni-ulm.de/xmlui/123456789/5299, http://nbn-resolving.de/urn:nbn:de:bsz:289-oparu-5299-7", "bibtexKey": "bercher2018hybrid" } , { "type" : "Publication", "id" : "https://puma.ub.uni-stuttgart.de/bibtex/279d52d5319e695f85873b882266e9e7c/droessler", "tags" : [ "afrika","algerien","fundamentalismus","islam","politik","politisches","system" ], "intraHash" : "79d52d5319e695f85873b882266e9e7c", "interHash" : "2392b395f7fcd175788b6c726bab22e7", "label" : "Algerien: Der islamische Fundamentalismus und die Krise des staatsbürokratischen Regimes", "user" : "droessler", "description" : "", "date" : "2019-03-11 13:59:50", "changeDate" : "2019-03-11 12:59:50", "count" : 1, "pub-type": "mastersthesis", "address":"Winterlingen", "year": "1993", "url": "", "author": [ "Isabella Pfaff" ], "authors": [ {"first" : "Isabella", "last" : "Pfaff"} ], "pages": "192", "bibtexKey": "pfaff1993algerien" } , { "type" : "Publication", "id" : "https://puma.ub.uni-stuttgart.de/bibtex/2cfcfce2755c874b822ee38f87cb65d11/droessler", "tags" : [ "International","Money","Reserve","US","beziehungen","currency","dollar","hegemonie","internationale","monetary","politik","politische","recognisability","system","usa","währung","ökonomie" ], "intraHash" : "cfcfce2755c874b822ee38f87cb65d11", "interHash" : "18c29075353a63ffe459dd8fc16e4ce8", "label" : "Rule of law and balance of power sustain US dollar preeminence", "user" : "droessler", "description" : "", "date" : "2018-02-26 10:04:53", "changeDate" : "2018-02-28 22:21:44", "count" : 1, "pub-type": "article", "journal": "Journal of Policy Modeling", "year": "2017", "url": "http://www.sciencedirect.com/science/article/pii/S0161893817300959", "author": [ "Elena Seghezza","Pierluigi Morelli" ], "authors": [ {"first" : "Elena", "last" : "Seghezza"}, {"first" : "Pierluigi", "last" : "Morelli"} ], "file" : ":1-s2.0-S0161893817300959-main.pdf:PDF", "issn" : "0161-8938", "groups" : "public", "intrahash" : "cfcfce2755c874b822ee38f87cb65d11", "interhash" : "18c29075353a63ffe459dd8fc16e4ce8", "doi" : "https://doi.org/10.1016/j.jpolmod.2017.09.004", "timestamp" : "2018-02-26 10:04:53", "username" : "droessler", "bibtexKey": "Seghezza2017" } ] }
