title: Evaluating an online learning community: Intellectual, social and emotional development and transformations.

authors: Khoo, Elaine G.L.

subjects: online teaching

abstract: Developing online learning communities is a promising pedagogical approach in online learning contexts for adult tertiary learners, but it is no easy task. Understanding how learning communities are formed and evaluating their efficacy in supporting teaching-learning involves a complex set of issues that have a bearing on the design and facilitation of successful online learning experiences. This paper presents findings of a case study of a semester-long online graduate course designed to facilitate a learning community at a New Zealand tertiary institution. It adopts a sociocultural analytical framework and argues for a multiple developmental analytical approach to evaluating learning that considers lecturer and student intellectual, social and emotional development and transformations. Implications are presented for online lecturers, course designers and institutional administrators.

title: An implementation of a compositional approach for verifying generalised nonblocking

authors: Francis, Rachel

subjects: computer science

abstract: Generalised nonblocking is a property of discrete-event systems which verifies liveness. It was introduced to overcome the weaknesses of standard nonblocking. Verifying generalised nonblocking of real-world models often involves exploring state-spaces which will exceed available memory. A compositional verification approach has been developed to achieve verification for models of a much larger size. For this project, we have developed the first implementation for compositionally verifying generalised nonblocking. In addition, we have experimented with the techniques used in compositional verification, and analysed their performance. Our algorithm has successfully verified a large set of industrial-size models, including at least one large model which had not been verified before.

title: Technology, culture and location in a recent New Zealand sonic art project

authors: Whalley, Ian

subjects: music

abstract: The HIEMPA (Hybrid Instruments from Electroacoustic Manipulation And Models of Pütorino and Aquascape) project combined a team of people with technical, artistic, environmental and cultural expertise toward the artistic outcome of extending the New Zealand sonic art tradition. The project involved collecting audio samples from the aquascape of the Ruakuri Caves and Nature Reserve in Waitomo, South Waikato, New Zealand; and samples of a variety of Pütorino – a New Zealand Mäori wind instrument. Following a machine learning analysis of this audio material and an analysis of the performance material, hybrid digital instruments were built and mapped to suitable hardware triggers. The new instruments are playable in real-time, along with the electroacoustic manipulation of Pütorino performances. The project takes into account the environmental and cultural significance of the source material, with the results to be released as a set of compositions. This paper discusses the research process.
