Book excerpt: Dynamic Coalitions denote a temporary collaboration between different entities to achieve a common goal. A key feature that distinguishes Dynamic Coalitions from static coalitions is Dynamic Membership, where new members can join and others can leave after a coalition is set. This thesis studies workflows in Dynamic Coalitions, by analyzing their features, highlighting their unique characteristics and similarities to other workflows, and investigating their relation with Dynamic Membership. For this purpose, we use the formal model of Event Structures and extend it to faithfully model scenarios taken as use cases from healthcare. Event Structures allow for workflows modeling in general, and for modeling Dynamic Membership in Dynamic Coalitions as well through capturing the join and leave events of members. To this end, we first extend Event Structures with Dynamic Causality to address the dynamic nature of DCs. Dynamic Causality allows some events to change the causal dependencies of other events in a structure. Then, we study the expressive power of the resulting Event Structures and show that they contribute only to a specific kind of changes in workflows, namely the pre-planned changes. Second, we present Evolving Structures in order to support ad-hoc and unforeseen changes in workflows, as required by the use cases. Evolving Structures connect different Event Structures with an evolution relation which allows for changing an Event Structure during a system run. We consider different approaches to model evolution and study their equivalences. Furthermore, we show that the history of a workflow should be preserved in our case of evolution in Dynamic Coalitions, and we allow for extracting changes from an evolution to support Process Learning. Third, to capture the goals of DCs, we equip Evolving Structures with constraints concerning the reachability of a set of events that represents a goal. The former extensions allow for examining the changes and evolutions caused by members, and examining members’ contributions to goal satisfaction, through their join and leave events. Finally, we highlight many modeling features posed as requirements by the domain of our Dynamic-Coalition use cases, namely the healthcare, which are independent from the nature of Dynamic Coalitions, e.g. timing. We examine the literature of Event Structures for supporting such features, and we identify that the notion of Priority is missing in Event Structures. To this end, we add Priority to various kinds of Event Structures from the literature. Furthermore, we study the relation between priority on one side, and conjunctive causality, disjunctive causality, causal ambiguity and various kinds of conflict on the other side. Comparing to Adaptive Workflows, which are concerned with evolutions of workflows that occur as a response to changes, e.g. changes in the business environment or exceptions, this thesis shows that Dynamic-Coalition workflows are not only Adaptive but also Goal-Oriented. Besides, it adds one extra trigger for evolution in workflows—unique to Dynamic Coalitions—namely the join of new members who contribute to goal satisfaction in a Dynamic Coalition. Finally the thesis contributes to bridging the gap in modeling between theory and domain experts by supporting step-by-step modeling applied regularly in healthcare and other domains. Dynamische Koalitionen (DKen) bezeichnen eine temporäre Kollaboration zwischen verschiedenen Entitäten zum Erreichen eines gemeinsamen Ziels. Ein Schüsselaspekt, welcher dynamische Koalitionen von statischen Koalitionen unterscheidet ist die dynamische Mitgliedschaft, durch die neue Mitglieder hinzu- kommen und andere die Koalitionen verlassen können, nachdem sie entstanden ist. Diese Arbeit studiert Workflows in dynamische Koalitionen durch eine Analyse ihrer Eigenschaften, das Herausstellen ihrer einzigartigen Charakteristika und Ähnlichkeiten zu anderen Workflows und durch eine Untersuchung ihrer Beziehung zu dynamischer Mitgliedschaft. In diesem Sinne nutzen wir das formales Model der Ereignisstukturen (ESen) und erweitern es, um Fallstudien aus der Medizin angemessen zu modellieren. ESen erlauben sowohl eine generelle Workflow Modellierung als auch eine Darstellung von Eintritt- und Austrittereignissen von Mitgliedern. Zu diesem Zweck erweitern wir ESen zuerst um Dynamische Kausalität, um die dynamische Natur von DKs abzubilden. Dynamische Kausalität erlaubt bestimmten Ereignissen die kausalen Abhängigkeiten anderer Ereignissen in einer Struktur zu verändern. Dann untersuchen wir die Ausdrucksstärke der resutierenden ESen und zeigen, dass sie nur eine spezifische Art der Veränderung abbilden, die sogenannten vorgeplanten Veränderungen. Als Zweites präsentieren wir Evolving in ESen um ad-hoc- und unvorhergesehene Veränderungen zu unterstützen, wie es durch unsere Fallstudien benötigt wird. Evolving in ESen verbinden verschiedene ESen mit einer Relation, welche eine Veränderung einer ES während eines Ablaufes erlaubt. Wir ziehen verschiedene Ansätze der Modelevolution in Betracht und untersuchen ihre Äquivalenzen. Des Weiteren zeigen wir, dass in unserem Fall der Evolution in DKen die Geschichte eines Workflows erhalten bleiben muss und wir ermöglichen das Extrahieren von Veränderungen einer Evolution, um Process Learning zu unterstützen. Drittens: Um die Ziele von DKen abzubilden, fügen wir den Evolving in ESen mit Einschränkungen bezüglich der Erreichbarkeit einer Menge von Ereignissen hinzu, welche das Ziel repräsentieren. Die genannten Erweiterungen erlauben es sowohl die Änderungen und Evolutionen, die vom Mitgliedern verursacht werden als auch die Beiträge der Mitglieder zur Zielerreichung durch deren Entritt- und Austrittereignissen zu untersuchen. Schlussendlich, stellen wir viele Modellierungseigen- schaften dar, welche von den DK-Fallstudien aus der Medizin benötigt werden und unabhängig von der Natur der DKen sind, wie z.B. Timing. Wir untersuchen die Literatur zu ESen bezüglich Unterstützung für solche Eigenschaften und stellen fest, dass der Begriff Priorität in ESen fehlt. Daher fügen wir Priorität zu verschiedenen ESen aus der Literatur hinzu. Des Weiteren untersuchen wir die Beziehungen von Priorität auf zu Konjunktiver Kausalität, disjunktiver Kausalität, kausal Uneindeutigkeit und verschiedenen Formen von Konflikt. Im Vergleich zu Adaptive Workflows, welche sich mit der Evolution von Workflows beschäftigt, die als Reaktion auf Veränderungen entsteht, wie z.B. Veränderungen im Business Environment oder Exceptions, zeigt diese Arbeit das DKen nicht nur adaptiv sondern auch zielorientiert sind. Außerdem fügt sie einen zusätzlichen Auslöser für Evolution in Workflows hinzu, welcher ausschließlich DKen eigen ist: das Hinzukommen neuer Mitglieder welche zur Ziel- erreichung der DK beitragen. Zuletzt trägt diese Arbeit bei, die Lücke der Modellierung zwischen der Theorie und den Domänenexperten zu überbrücken, in dem sie eine Schritt-für-Schritt Modellierung unterstützt, welche regelmäßig in der Medizin und anderen Bereichen angewand wird.

Book excerpt: We present a theory of dynamic coalitions for a legislative bargaining game in which policies continue in effect in the absence of new legislation. We characterize Markov perfect equilibria with dynamic coalitions, which are decisive sets of legislators whose members strictly prefer preserving the coalition to having it end. Dynamic coalitions satisfy internal stability and exclusion risk conditions. They can be minimal winning or surplus and can award positive allocations to non-coalition members. Policies supported can be efficient or inefficient. Vested interests can support policies that no legislator would propose if forming a new coalition. If uncertainty is associated with policy implementation, a continuum of policies are supported. These equilibria have the same allocation in every period when the coalition persists. Dynamic coalitions also exist in which members tolerate a degree of implementation uncertainty, resulting in policies that can change without the coalition dissolving. We compare to experimental results.

Book excerpt: The combination of participating organizations in a coalition operation often changes over time; the coalition is dynamic and evolves over the course of its mission. A given organization may participate in the coalition only at the stage where its expertise or resources are most needed, while other organizations may participate through the entire course of the operation. As these are independent organizations coming together for a limited time to meet a specific goal, the structure of the coalition must be able to accommodate the different command arrangements, procedures, and other characteristics of each organization. In order to develop a theory of a coalition structure that can accommodate the changing needs of the coalition, a dynamic model of a coalition is being developed that allows organizational participation to fluctuate over the course of the mission. In order to ensure that the model emulates real world situations, a scenario was created from actual coalition experiences in the NATO-led Balkan's peacekeeping operations in Kosovo, where lead nations were assigned under the operational command of the NATO-led force. Adding to the complexity of the operations was the fact that military commanders and staff turned over frequently creating stability and continuity of operations challenges. This project attempts to capture some of these dynamics in order to draw conclusions about the effect of change on the coalition structure.

Available in PDF, EPUB and Kindle. Book excerpt: This thesis presents a gradient play differential game in a producer market with linear demand as a model of behavior in a competitive environment. This model is then extended to allow for cooperation. Definitions of coalitions and natural coalitions are provided, and previous work dealing with static coalition structure is presented. Requirements for acceptable system dynamics are given, and a specific set of dynamics presented. These dynamics are shown to meet the specified requirements in a number of cases through proofs of stability of equilibria as well as guarantees that the dynamics result in natural coalitions. Numerical examples are provided to support the claim that a reasonable equilibrium exists and that its basin of attraction covers reasonable initial conditions. The work concludes with a summary as well as possible paths for continued research.

Available in PDF, EPUB and Kindle. Book excerpt: The labor movement sees coalitions as a key tool for union revitalization and social change, but there is little analysis of what makes them successful or the factors that make them fail. Amanda Tattersall—an organizer and labor scholar—addresses this gap in the first internationally comparative study of coalitions between unions and community organizations. She argues that coalition success must be measured by two criteria: whether campaigns produce social change and whether they sustain organizational strength over time. The book contributes new, practical frameworks and insights that will help guide union and community organizers across the globe. The book throws down the gauntlet to industrial relations scholars and labor organizers, making a compelling case for unions to build coalitions that wield "power with" community organizations. Tattersall presents three detailed case studies: the public education coalition in Sydney, the Ontario Health Coalition in Toronto, and the living wage campaign run by the Grassroots Collaborative in Chicago. Together they enable Tattersall to explore when and how coalition unionism is the best and most appropriate strategy for social change, organizational development, and union renewal. Power in Coalition presents clear lessons. She suggests that "less is more," because it is often easier to build stronger coalitions with fewer organizations making decisions and sharing resources. The role of the individual, she finds, is traditionally underestimated, even though a coalition's success depends on a leader's ability to broker relationships between organizations while developing the campaign's strategy. The crafting of goals that combine organizational interest and the public interest and take into account electoral politics are crucial elements of coalition success.
