We introduce the ActivityFlow specification language for flexible specification, composition, and coordination of workflow activities. The most interesting features of the ActivityFlow specification language include (1) a collection of specification mechanisms allowing workflow designers to use a uniform workflow specification interface to describe different types (i.e., ad-hoc, administrative, or production) of workflows involved in their organizational processes (an objective of this feature is to help increase the flexibility of workflow processes in accommodating changes); (2) a set of activity modeling facilities, enabling workflow designers to describe the flow of work declaratively and incrementally, allowing reasoning about correctness and security of complex workflow activities independently from their underlying implementation mechanisms; (3) an open architecture that supports user interaction as well as collaboration of workflow systems of different organizations.

This chapter presents a framework for dynamic restructuring of long-running business processes. The framework is composed of the ActivityFlow specification language, a set of workflow restructuring operators, and a dynamic workflow management engine. The ActivityFlow specification language enables the flexible specification, composition, and coordination of workflow activities. There are three unique features of our framework design. First, it supports a collection of specification mechanisms, allowing workflow designers to use a uniform workflow specification interface to describe different types of workflows involved in their organizational processes. A main objective of this characteristic is to help increase the flexibility of workflow processes in accommodating changes. The ActivityFlow language also provides a set of activity modeling facilities, enabling workflow designers to describe the flow of work declaratively and incrementally, and allowing to reason about correctness and security of

SYNOPSIS: In 2005, an ad hoc committee appointed by the American Accounting Association (AAA) documented a crisis-level shortage of accounting Ph.D.s and recommended significant structural changes to doctoral programs (Kachelmeier, Madeo, Plumlee, Pratt, and Krull 2005). However, subsequent studies show that the shortage continues and the cumulative costs grow (e.g., Fogarty and Holder 2012; Brink, Glasscock, and Wier 2012). The Association to Advance Collegiate Schools of Business (AACSB) recently called for renewed attention to the problem (AACSB 2013b). We contribute to the literature by providing updated information regarding responses by doctoral programs and, from the eyes of potential candidates, of continuing impediments to solving the doctoral shortage. In this paper, we present information gathered through surveys of program administrators and master's and Accounting Doctoral Scholars Program (ADS) students. We explore (1) the cumulative impact of the Ph.D. shortage as of 2013, including its impact on accounting faculty composition, across different types of institutions, (2) negative student perceptions of Ph.D. programs and academic accounting careers, which discourage applicants from pursuing Ph.D. programs, and (3) impediments facing institutions in expanding doctoral programs.

Sample Set

The emergence of ubiquitous computing (UbiComp) environments has increased the risk of undesired access to individuals’ physical space or their information, anytime and anywhere, raising potentially serious privacy concerns. Individuals lack awareness and control of the vulnerabilities in everyday contexts and need support and care in regulating disclosures to their physical and digital selves. Existing GUI-based solutions, however, often feel physically interruptive, socially disruptive, time-consuming and cumbersome. To address such challenges, we investigate the user interaction experience and discuss the need for more tangible and embodied interactions for effective and seamless natural privacy management in everyday UbiComp settings. We propose the Privacy Care interaction framework, which is rooted in the literature of privacy management and tangible computing. Keeping users at the center, Awareness and Control are established as the core parts of our framework. This is supported with three interrelated interaction tenets: Direct, Ready-to-Hand, and Contextual . Direct refers to intuitiveness through metaphor usage. Ready-to-Hand supports granularity, non-intrusiveness, and ad hoc management, through periphery-to-center style attention transitions. Contextual supports customization through modularity and configurability. Together, they aim to provide experience of an embodied privacy care with varied interactions that are calming and yet actively empowering. The framework provides designers of such care with a basis to refer to, to generate effective tangible tools for privacy management in everyday settings. Through five semi-structured focus groups, we explore the privacy challenges faced by a sample set of 15 older adults (aged 60+) across their cyber-physical-social spaces. The results show conformity to our framework, demonstrating the relevance of the facets of the framework to the design of privacy management tools in everyday UbiComp contexts.

This concluding chapter demonstrates the concept of the stained-glass labyrinth by providing an overview of gendered barriers identified in each chapter and ways different types of gendered organizational processes reinforce normative gender structure both within these organizations and in broader society. It illustrates how gendered processes on the individual, interactional, organizational, and societal levels are mutually reinforcing in ways that result in unequal outcomes between men and women. In particular, this chapter illustrates how normative gender structure within CBF congregations presents barriers for women pastors in these contexts thereby reinforcing their underrepresentation in leadership positions. Finally, this chapter reiterates previous chapters by emphasizing organizational (structural) change. Instead of exclusively expecting women pastors to adopt strategies to maneuver better through organizational gendered barriers and resist sexism, this work calls on organizations to change the gender structure itself so that women no longer have to clear unequal and sizeable hurdles on their paths to pastoral positions and in their positions as pastors. For it is only through structural change that gender equality can be fully realized.

Recent seismic events are a unique opportunity to monitor and collect details of direct repair costs and the downtimes associated with massive reconstruction processes. This paper focuses on the actual repair costs of five RC buildings damaged by the 2009 L'Aquila earthquake. The repair costs for structural and nonstructural components that experienced different types of earthquake damage are discussed and then used as a benchmark for the predictions. The comparison at both the building and component levels revealed that the FEMA P-58 methodology is suitable, in general, for application to different types of building stock. Ad hoc upgrades to the FEMA fragility database for components that are typical of the Mediterranean area are required. When implementing the proposed modifications, a reasonable level of consistency is achieved in terms of actual and predicted repair costs (differences in the range of 30–48%). A discussion on the actual repair costs and the main differences with the predicted costs for infills and partitions, structural subassemblies, floor finishes, and other acceleration-sensitive nonstructural components is provided, along with suggestions for further improving.

Cooperative learning is a means of providing opportunities for students to work together in an effort to accomplish an assigned intellectual task. There are different types of cooperative learning. In formal settings, students may stay in a learning group for several sessions in order to achieve a specific task. More informal cooperative learning situations usually are temporary or ad hoc groups that are formed by professors to facilitate some form of discussion and learning. In a cooperative learning class, it is important to clearly explain the pedagogical purposes and the required procedures of the course. Instructors should explain how an active learning course works and the responsibilities students have in this kind of course. An effective cooperative learning course demands the instructor’s active participation, as they must monitor the groups, answer research questions, and generally guide the direction of the course discussions. Though there are disadvantages and criticisms against cooperative learning, the study of international relations in particular can benefit from this method. The study of international relations is defined by problems and challenges that are interdisciplinary. Students thus need to be prepared for research and problem-solving in a variety of issue areas. Cooperative learning techniques that provide for the sharing of expertise and research findings with peers provide students with skills that are critical for success in the world today.

This article contributes to current debates on urban austerity by comparing public land privatisations in French and Italian cities. These privatisations have emerged in several countries during the last two decades as a recurring austerity measure. However, current research does not explain how similar national austerity policies result in diverse urban outcomes. This article tackles this limitation by developing an analytical model of the different types of urban austerity. It uses the intergovernmental system and local policy capacity as the main variables to explain four local patterns of austerity, that is, gridlock austerity, nationally mitigated austerity, locally mitigated austerity and opportunistic austerity. Drawing on nine case studies covering two public landowners, the article shows that public land austerity policies have become routine practice based on compromises in French cities, but conflictual and based on ad hoc solutions in Italian cities.
