  • how social dynamics and the context of digital content impact workplace remix
    Human Factors in Computing Systems, 2018
    Co-Authors: Jessica L Feuston, Siân Lindley
    Abstract:

    As highlighted in recent work on remix in online content creation communities, people commonly take and appropriate digital content for new activities. Less is known, however, about how people repurpose digital content as part of work. We report findings from an interview study with 19 individuals in which we explored how digital content in the workplace becomes a material for remix. Our analysis emphasizes (i) how digital content is obtained from colleagues for remix, (ii) how content is made available for remix by others, and (iii) how digital content is transformed for remix. In attending to these broader processes of remix, we consider the roles of workplace technologies, such as those for file sharing, as well as social norms that Mediate Access, remix, and acknowledgement. We draw implications for design of technology that emphasize support for individuals in making digital content available for remix, and raising awareness of the context of that content.

  • POPL - From sequential programs to multi-tier applications by program transformation
    Proceedings of the 32nd ACM SIGPLAN-SIGACT sysposium on Principles of programming languages - POPL '05, 2005
    Co-Authors: Matthias Neubauer, Peter Thiemann
    Abstract:

    Modern applications are designed in multiple tiers to separate concerns. Since each tier may run at a separate location, middleware is required to Mediate Access between tiers. However, introducing this middleware is tiresome and error-prone.We propose a multi-tier calculus and a splitting transformation to address this problem. The multi-tier calculus serves as a sequential core programming language for constructing a multi-tier application. The application can be developed in the sequential setting. Splitting extracts one process per tier from the sequential program such that their concurrent execution behaves like the original program.The splitting transformation starts from an assignment of primitive operations to tiers. A program analysis determines communication requirements and inserts remote procedure calls. The next transformation step performs resource pooling: it optimizes the communication behavior by transforming sequences of remote procedure calls to a stream-based protocol. The final transformation step splits the resulting program into separate communicating processes.The multi-tier calculus is also applicable to the construction of interactive Web applications. It facilitates their development by providing a uniform programming framework for client-side and server-side programming.

  • AsiaCCS - Automated Synthesis of Run-time Monitors to Enforce Authorization Policies in Business Processes
    Proceedings of the 10th ACM Symposium on Information Computer and Communications Security, 2015
    Co-Authors: Clara Bertolissi, Daniel Ricardo Dos Santos, Silvio Ranise
    Abstract:

    Run-time monitors are crucial to the development of security-aware workflow management systems, which need to Mediate Access to their resources by enforcing authorization policies and constraints, such as Separation of Duty. In this paper, we introduce a precise technique to synthesize run-time monitors capable of ensuring the successful termination of workflows while enforcing authorization policies and constraints. An extensive experimental evaluation shows the scalability of our technique on the important class of hierarchically specified security-sensitive workflows with several hundreds of tasks.

  • A SMT-based methodology for monitoring of security-aware workflows
    International Journal of Internet Technology and Secured Transactions, 2014
    Co-Authors: Clara Bertolissi, Silvio Ranise
    Abstract:

    Run-time monitors are crucial to the development of security-aware workflow management systems, which are at the heart of modern e-services and need to Mediate Access to their resources by imposing authorisation constraints (e.g., separation of duty). In this paper, we propose a new methodology to build run-time monitors capable of ensuring the successful termination of workflows subject to authorisation constraints. The methodology is based on state-of-the-art satisfiability modulo theories techniques.
