title: Generating group agreement in cooperative computer-mediated groups: Towards an integrative model of group interaction

authors: Whitworth, Brian

abstract: This study addresses the problem of generating agreement in computer-mediated groups.
The key entities of group interaction are proposed to be the task, the other individuals, and the group. Extending this three way categorisation across the input-process-output framework suggests an integrative model with three processes (task resolution, interpersonal relating, and group representation), three levels of social influence (informational influence, personal influence, and normative influence), and three types of output (task results, relationships, and agreement).
The background upon which these processes operate is the communication setting. A proposed taxonomy of communication settings suggests the natural setting for generating electronic group agreement is asynchronous, many-to-many interaction.
Describing non-task group activities as "process losses" denies group combining behaviour, and raises the "group effectiveness paradox", where groups expend more effort to produce less. The integrative model accounts for group activities without paradox.
The generation of agreement in cooperative groups is attributed to the "identification" of individuals with the group. Members who identify with a group, tend to accept the group's decisions as their own. This process may use relatively simple position information embedded within multi-threaded communications, rather than complex "social" information. If so, computer-mediated groups can enact agreement across plain text networks.
Software was written to simulate asynchronous, many-to-many exchange of position information. Anonymous computer-mediated groups sat multi-choice tests under blind, group aware and confidence aware conditions. The exchange of position information alone produced a significant change in agreement, although neither medium nor exchanged information were "rich", no reasons were given, and there was no personal "presence" or discussion.
It was concluded that computer-mediated groups can enact agreement. The method adopted, of isolating one process within a single communication setting, is recommended for research. However for practical implementation, a balance of all three processes is suggested, as all have a role in group interaction.

title: Stratigraphy and development of the Late Miocene-Early Pleistocene Hawke’s Bay forearc basin

authors: Bland, Kyle J.

subjects: Hawke’s Bay

abstract: A Late Miocene-Early Pleistocene mixed carbonate-siliciclastic sedimentary succession about 2 500 m thick in the Hawke’s Bay forearc basin is the focus of a basin analysis. The area under investigation covers 3 500 km2 of western and central Hawke’s Bay. The stratigraphy of Hawke’s Bay Basin is characterised by dramatic vertical and lateral facies changes and significant fluxes of siliciclastic sediment through the Late Miocene and Pliocene. This project aims to better understand the character and origin of the sedimentary succession in the basin. Geological mapping has been undertaken at a scale of 1:25000, with data managed in an ARCINFO geodatabase, following the database model employed in the IGNS QMap programme.
Along the western margin of the basin there is progressive southward onlap of late Cenozoic strata on to basement. The oldest units are of Late Miocene (Tongaporutuan) age and the youngest onlap units are of latest Pliocene (Nukumaruan) age. Geological mapping of the basin fill places constraints on the magnitude (about 10 km) and timing (Pleistocene) of most of the offset on the North Island Shear Belt.
Lithofacies have been described and interpreted representing fluvial, estuarine, shoreface and inner- to outer-shelf environments. Conglomerate facies are representative of sediment-saturated prograding fluvial braidplains and river deltas. These units are dominated by greywacke gravels and record the erosion of the Kaweka-Ahimanawa Ranges. Sandstone facies typically comprise very well sorted, clean non-cemented units of 10-50 m thickness that accumulated in innershelf environments. Siltstone facies probably accumulated in relatively quiet, middle- to outer-shelf water depths, and comprise well-sorted, firm non-cemented units with occasional tephra interbeds. Limestone facies represent examples of continent-attached cool-water carbonate systems that developed in response to strong tidal currents and a high nutrient flux during the Pliocene. These facies are examples of mixed siliciclastic-bioclastic sedimentary systems. Of these facies the widespread distribution and thickness of sandstone and limestone units present the most potential for hydrocarbon reservoirs. Similarly, the distribution of siltstone and mudstone beds provides adequate seal rocks. Mangapanian limestone facies have already been targeted as potential petroleum reservoirs (e.g. Kereru-1). Geological mapping suggests that potential hydrocarbon reservoir and seal rocks occur extensively in the subsurface.

title: Putting the draft learning progression framework - Maori in the New Zealand Curriculum - to work: An Illustration

authors: Johnson, Diane

subjects: Māori language education

abstract: How language curricula are implemented in the classroom is of critical importance. Here, we take one achievement objective from the draft Learning Progression Framework for Māori in mainstream classes and demonstrate one way in which it can be realised as a core integrated skills lesson, that is, as a lesson that introduces new language (core lesson) through all four skills - reading, writing, listening and speaking (an integrated skills lesson). The lesson is preceded by a discussion of the type of planning that accompanies the implementation of language curricula.
