title: Considering photographs never taken during photo-production projects

authors: Hodgetts, Darrin

subjects: homelessness

abstract: The visual medium is central to how most of us navigate daily life and come to know and interact with our social worlds. Recently, the role of visual dimensions of everyday life has surfaced in qualitative research in psychology. This paper explores some of the underlying processes foundational to participants' efforts to picture their worlds during photo-production projects. We draw on excerpts from a study of images of homelessness in London to exemplify various methodological issues surrounding the interpretation of photo-production materials. Emphasis is placed on the need to focus on photo-production because photographs taken never fully contain what is important to participants. Issues and events are often talked into the frame of photographs by participants. This process of presenting aspects of one's life extends to discussions of photographs not taken and reflections on processes of picturing everyday life. We argue that a consideration of photographs not taken is important if we are to maximise the utility of photo-production as a method and fully understand what it provides.

title: A compositional approach for verifying generalized nonblocking

authors: Malik, Robi

subjects: computer science

abstract: This paper proposes a compositional approach to verify the generalised nonblocking property of discrete-event systems. Generalised nonblocking is introduced in to overcome weaknesses of the standard nonblocking check in discrete-event systems and increase the scope of liveness properties that can be handled. This paper addresses the question of how generalised nonblocking can be verified efficiently. The explicit construction of the complete state space is avoided by first composing and simplifying individual components in ways that preserve generalised nonblocking. The paper extends and generalises previous results about compositional verification of standard nonblocking and lists a new set of computationally feasible abstraction rules for standard and generalised nonblocking.

title: Kuta (Eleocharis sphacelata, Cyperaceae), a locally important and highly valued weaving plant

authors: Wehi, Priscilla M.

subjects: Northland (N.Z.)

abstract: This article introduces and discusses kuta (Eleocharis sphacelata, Cyperaceae), a tall spikerush found on the margins of shallow lakes in New Zealand, which, although often overlooked, is considered in Northland to be a valuable weaving resource.
