title: Improved grid integration of intermittent electricity generation using electric vehicles for storage: A simulation study

authors: Monigatti, Paul

subjects: electric vehicles

abstract: This paper describes a simulation to establish the extent to which reliance on non-dispatchable energy sources, particularly wind generation, could in the future be extended beyond accepted norms, by utilizing the distributed battery capacity of an electric vehicle fleet for storage. The notion of exploiting the distributed battery capacity of an electric vehicle fleet as grid storage is not new. However, this simulation study specifically examines the potential impact of the idea in the New Zealand context. The simulation makes use of real and projected data in relation to vehicle usage, full potential wind generation capacity and availability, taking into account weather variation, and typical daily and seasonal patterns of electricity usage. It differs from previous studies in that it is based on individual vehicles, rather than a bulk battery model. At this stage, the simulation does not take into account local or regional flows. A more detailed analysis of these localized effects will follow in subsequent stages of the simulation work.

title: What wrist should you wear your actigraphy device on? Analysis of dominant vs. non-dominant wrist actigraphy for measuring sleep in healthy adults

authors: Driller, Matthew W.

subjects: polysomnography

abstract: OBJECTIVE: Differences in sleep results due to the placement of actigraphy devices (non-dominant vs. dominant wrist) are yet to be determined. 
METHODS: 65 nights of data from 13 adult participants was collected while participants wore two actigraphy devices, one on each wrist. Sleep indices including total sleep time (TST), total time in bed (TTB), sleep efficiency (SE%), sleep latency (SL), wake after sleep onset (WASO), sleep onset time (SOT) and wake time (WT) were assessed between the two devices. 
RESULTS: There were no significant differences between devices for any of the measured sleep variables (p>0.05). SE%, SL and WASO resulted in high correlations between devices (0.89, 0.89 and 0.76, respectively), with all other sleep variables resulting in very high correlations (>0.90) between devices.
CONCLUSIONS: Based on our results, it does not seem critical which wrist the actigraphy device is worn on for measuring key sleep variables.

title: Dis-lodging literature from English: Challenging linguistic hegemonies

authors: Locke, Terry

subjects: literature

abstract: This paper problematises the location of literature "teaching" within the English (L1) curriculum, as is the case in New Zealand and other settings. It defamiliarises this arrangement by drawing attention to official New Zealand policies of biculturalism and to the increasing cultural and linguistic diversity in many New Zealand classrooms. It identifies a number of social justice issues arising from the current arrangement, and also raises issues in respect of educational policy and ways in which canonical subjects become constructed in practice. It then discusses ways in which a new qualifications template developed at the University of Waikato might provide a vehicle for establishing a new arrangement, in terms of which literature study is dislodged from English and reshaped as a course of study entitled Literature in Society. It indicates ways in which Comparative Literature, as a predominantly university-constituted discipline, might contribute to the theorisation of this new arrangement.
