Title: Towards translating activity states framework for the analysis
of cross-domain collaboration process during software development.
Speaker: Nik Nailah Binti Abdullah, GRACE Center, NII
Abstract:
Activity states framework is a communication analysis that applies
cognition theories (situated cognition, activity theory, hierarchy on
learning and communication) to make sense of communication activities
during mediated cross-domain collaboration. Mediated cross-domain
collaboration is where different experts use the Web media (e.g.,
instant messaging, video-conferencing meeting) to collaborate
together. This may result in emerging practices among them for several
reasons: (i) where the expert(s) is new to the group; (ii) the experts
have just started a new practice of mediated collaboration; (iii) the
mediated tools being used may influence the emerging practices.
Therefore, it is important to identify the emerging practices for
building situated tools that can effectively support the
collaboration. However the challenge is to make sense the mediated
communications because they are in nature asynchronous, making it
challenging to identify: who said what to whom and what are they
doing? Hence activity states was developed first and foremost as a
method to organize and make sense of communication exchanges. The
framework applies cognition concepts (e.g. conceptualization,
contextualism) for designing a computer program so that it can: (i)
know what to look for; (ii) what to do next; and then (iii) capture
the communication exchanges into agent messages and finally (iv)
translate the agent messages into activities (e.g., debugging,
organizing schedule A, discuss about deliverables). Based on the
framework, we can detect automatically at every moment on a chat
system during collaboration the kind of activities that
emerge. Moreover we are able to detect patterns of regularities in
“expert’s responses” to “similar contexts” during collaboration.
Under the Grace center, and in collaboration with the Empirical
Studies of Software Development (ESSD) and Software Engineering (SEAD)
group at the Department of Mathematics and Computing, Open University
(UK), we are presently translating the framework for analyzing
co-located cross-domain collaboration process during software
development.
In this talk I will introduce activity states framework, and then the
ongoing research to capitalize the framework (focused on learning and
communication) for analyzing collaboration process during software
development.
Biography:
Dr Nik Nailah Binti Abdullah received both her master and doctoral
degree in Computer Science (specializing in Cognitive Science) from
Universite’ of Sciences and Techniques Montpellier II,
France. Currently she is a post-doctoral researcher under the
principal investigator Professor Shinichi Honiden at the Honiden
Laboratory, National Institute of Informatics, Tokyo, Japan. Her
interests are in general on theories on learning, communication, and
memory from cognitive science, ethnography, and human computer
interaction. Currently she holds a visiting research fellow position
at the Department of Mathematics and Computing, Open University where
she collaborates with Professor Helen Sharp, leader of Empirical
Studies of Software Development research group. She has been invited
to give several technical talks about her research on developing
activity states framework, most recently as a guest speaker during
Google Tech Talk, at Google Mountain View, California, in October
2008. She was also nominated as a finalist for the Blackberry Women
and Technology Award associated to IFIP in 2008, Milan, Italy under
the theme: Affective Computing, Interaction and Dialogues on the
future Web.

Title: Infrastructures for Authorization and Access Control
Speaker: Gunther Pernul, University of Regensburg, Germany
Abstract:
In this talk we argue that traditional approaches for authorization
and access control in computer systems (i.e., discretionary,
mandatory, and role-based access controls) are not appropriate to
address the requirements of networked or distributed systems, and that
proper authorization and access control requires infrastructural
support in one way or another. This support can be provided, for
example, by an authentication and authorization infrastructure
(AAI). Against this background, we overview, analyze, discuss, and put
into perspective some of the current technologies that can be used to
build and operate AAIs. A privilege management infrastructure (PMI) is
one step further and able to support a comprehensive authorization
service. Several new approaches for privilege management have emerged
by dynamically controlling the users accesses based on exchanging and
evaluating general user characteristics, most notable the
attribute-based access control model (ABAC). During the talk we will
develop a PMI service model as a reference that includes ABAC
functionality and is based on the OASIS XACML specifications and
lessons learned from different existing AAIs. Some of our work is
carried out within the European research projects FP6 Access-eGov
(http://www.accessegov.org ) aiming for a European-wide e-Government
service platform and FP7 SPIKE (http://www.spike-project.eu) aiming
for the development of a collaboration platform for the networked
enterprises.
Biography:
Gunther Pernul received diploma and doctoral degrees both from the
University of Vienna, Austria. Currently he is a chaired full
professor and managing director of the Department of Information
Systems at the University of Regensburg, Germany. His research
interests are information systems in general, with currently focus on
the information web and information and application security. In these
areas he is co-author of a text book, has edited or co-edited ten
books, and published more than 100 papers in scientific journals and
conference proceedings. Dr. Pernul is a member of ACM, IEEE, GI, OCG,
member of the IFIP WG 11.3 and observer of the IFIP WG 11.8 (Security
Education). He serves on the steering board of the Communications and
Multimedia Security (CMS) and is cofounder of the EC-Web (since 2000)
and TrustBus (since 2004) conference series. He has been involved in
several research projects on national and international
levels. Currently he is acting as principal investigator and
coordinator of the European FP7 SPIKE and IPICS and the national
funded SecPat projects.
