title: eLearning lecturer workload: Working smarter or working harder?

authors: Bright, Stephen

subjects: lecturer workload

abstract: Lecturers who move into the online learning environment often discover that the workload involved not only changes, but can be overwhelming as they cope with using digital technologies. Questions arise, given the dissatisfaction of lecturers with lowering morale and increasing workload, whether future expansion of this teaching component in tertiary institutions is sustainable. The challenge facing lecturers now, and in the future, is about learning workload management strategies which effectively manage the workload they encounter in the online learning environment. This paper describes a case study (which is a work-in-progress) examining the perceptions of online workload cf. face-to-face teaching of lecturers who are experienced in e-teaching. As well, it identifies strategies the lecturers have developed or adopted to manage this element of their workload.

title: Shape and deformation measurement using heterodyne range imaging technology

authors: Conroy, Richard M.

abstract: Range imaging is emerging as a promising alternative technology for applications that require non-contact visual inspection of object deformation and shape. Previously, we presented a solid-state full-field heterodyne range imaging device capable of capturing three-dimensional images with sub-millimetre range resolution. Using a heterodyne indirect time-of-flight configuration, this system simultaneously measures distance (and intensity), for each pixel in a cameras field of view. In this paper we briefly describe our range imaging system, and its principle of operation. By performing measurements on several metal objects, we demonstrate the potential capabilities of this technology for surface profiling and deformation measurement. In addition to verifying system performance, the reported examples highlight some important system limitations. With these in mind we subsequently discuss the further developments required to enable the use of this device as a robust and practical tool in non-destructive testing and measurement applications.

title: Memento Mori : Memento Maori – moko and memory

authors: Te Awekotuku, Ngahuia

subjects: tangi

abstract: Moko patterns, mau moko, “wearing ink” is often explained as an act of remembrance, a symbol of honour or success, of grieving or loss. Memento mori, remembering the dead and remembrance of death, pervades the Maori world, and is profoundly expressed in customary practice – haehae, upoko tuhi, and ta moko. These embodied and visceral experiences are described in waiata tangi, in whai korero, in moteatea, in the traditional context, and graphically recorded on the living flesh in our contemporary world. Mau moko celebrates identity, so modern memorial ornamentation mourns and reflects on this in ‘memento mori’; and also reinforces and engages reality in the correspondent notion of ‘memento Maori’; an assertion that claims dominion and understanding across generations, across time, across space.
