The life-history and relationships of ‘Orthocladius’ pictipennis Freeman (Diptera: Chironomidae)

The previously unknown larva and pupa of ‘Orthocladius’ pictipennis Freeman have been found, and associated by molecular means. Pharate pupae (males within pupae) allow the link to the described adult. We describe the larva and pupa, and provide short notes on the adult. The taxon is unrelated to Orthocladius – no members of this Holarctic genus are present in New Zealand – and therefore we provide a new generic name, Paulfreemania Cranston and Krosch gen. n. as well as a short discussion of relationships amongst austral Orthocladiinae.

A preliminary OSL chronology for coastal dunes on Moreton island, Queensland, Australia – Marginal deposits of A large-scale quaternary shelf sediment system

Moreton Island and several other large siliceous sand dune islands and mainland barrier deposits in SE Queensland represent the distal, onshore component of an extensive Quaternary continental shelf sediment system. This sediment has been transported up to 1000 km along the coast and shelf of SE Australia over multiple glacioeustatic sea-level cycles. Stratigraphic relationships and a preliminary Optically Stimulated Luminance (OSL) chronology for Moreton Island indicate a middle Pleistocene age for the large majority of the deposit. Dune units exposed in the centre of the island and on the east coast have OSL ages that indicate deposition occurred between approximately 540 ka and 350 ka BP, and at around 96±10 ka BP. Much of the southern half of the island has a veneer of much younger sediment, with OSL ages of 0.90±0.11 ka, 1.28±0.16 ka, 5.75±0.53 ka and <0.45 ka BP. The younger deposits were partially derived from the reworking of the upper leached zone of the much older dunes. A large parabolic dune at the northern end of the island, OSL age of 9.90±1.0 ka BP, and palaeosol exposures that extend below present sea level suggest the Pleistocene dunes were sourced from shorelines positioned several to tens of metres lower than, and up to few kilometres seaward of the present shoreline. Given the lower gradient of the inner shelf a few km seaward of the island, it seems likely that periods of intermediate sea level (e.g. ~20 m below present) produced strongly positive onshore sediment budgets and the mobilisation of dunes inland to form much of what now comprises Moreton Island. The new OSL ages and comprehensive OSL chronology for the Cooloola deposit, 100 km north of Moreton Island, indicate that the bulk of the coastal dune deposits in SE Queensland were emplaced between approximately 540 ka BP and prior to the Last Interglacial. This chronostratigraphic information improves our fundamental understanding of long-term sediment transport and accumulation on large-scale continental shelf sediment systems.

Exchange relationships in building services maintenance activity : a test of transaction cost economics and the resource dependency view

The firm is faced with a decision concerning the nature of intra-organizational exchange relationships with internal human resources and the nature or inter-organizational exchange relationships with market firms. In both situations, the firm can develop an exchange that ranges from a discrete exchange to a relational exchange. Transaction Cost Economics (TCE) and the Resource Dependency View (RDV) represent alternative efficiency-based explanations fo the nature of the exchange relationship. The aim of the paper is to test these two theories in respect of air conditioning maintenance in retail centres. Multiple sources of information are genereated from case studies of Australian retail centres to test these theories in respoect of internalized operations management (concerning strategic aspects of air conditioning maintenance) and externalized planned routine air conditioning maintenance. The analysis of the data centres on pattern matching. It is concluded that the data supports TCE - on the basis of a development in TCE's contractual schema. Further research is suggested towards taking a pluralistic stance and developing a combined efficiency and power hypothesis - upon which Williamson has speculated. For practice, the conclusions also offer a timely cautionary note concerning the adoption of one approach in all exchange relationships.

Relationships between employees and their nomadic, non-territorial work environment

Recent and current socio-cultural trends are significant factors impacting on how business is conduced and correspondingly, on how work environments are designed. New communication technology is helping to break physical boundaries and change the way and speed of conducting business. One of the main characteristics of these new workplaces is non-permanency wherein the individual employee has no dedicated personally assigned office, work station, or desk. In this non-territorial, nomadic situation, employees undertake their work tasks in a wide variety of work settings inside and outside the office building. Such environments are understood to be must suitable where there is the need for high interaction with others as well as a high level of concentrated, independent work. This thesis reports on a project designed to develop a deeper understanding of the relationships between people (P) and their built environment (E) in the context of everyday work practice in a nomadic and non-territorial work environment. To achieve this, the study focuses on the experiences of employees as they understand them in relation to their work and the designed/ physical work environment. In this sense, the study is qualitative and grounded in nature. It does not assume any previously established theory nor test any presenting hypothesis. Instead it interviews the participants about their situations at work in their workplace, interprets natural interaction and creates a foundation for the development of theory informing workplace design, particularly theory that recognises the human nature of work and the need, as highlighted by several seminal researchers, for a greater understanding of how people manage and adapt in dynamic work environments.

Enriching relationships : community engagment toward sustainable coastal futures

Coastal communities face the social, cultural and environmental challenges of managing rapid urban and industrial development, expanding tourism, and sensitive ecological environments. Enriching relationships between communities and universities through a structured engagement process can deliver integrated options towards sustainable coastal futures. This process draws on the embedded knowledge and values of all participants in the relationship, and offers a wide and affordable range of options for the future. This paper reviews lessons learnt from two projects with coastal communities, and discusses their application in a third. Queensland University of Technology has formed collaborative partnerships with industry in Queensland's Wide Bay-Burnett region to undertake a series of planning and design projects with community engagement as a central process. Senior students worked with community and produced design and planning drawings and reports outlining future options for project areas. A reflective approach has been adopted by the authors to assess the engagement process and outcomes of each project to learn lessons to apply in the next. Methods include surveying community and student participants regarding the value they place on process and outcomes respectively in planning for a sustainable future. All project participants surveyed have placed high importance on the process of engagement, emphasising the value of developing relationships between all project partners. The quality of these relationships is central to planning for sustainable futures, and while the outcomes the students deliver are valued, it is as much for their catalytic role as for their contents. Design and planning projects through community engagement have been found to develop innovative responses to the challenges faced by coastal communities seeking direction toward sustainable futures. The enrichment of engagement relationships and processes has an important influence on the quality of these design and planning responses.

Teachers’ understandings of their relationships with students : pedagogic connectedness

This paper reports on a doctoral study that explored the nature of pedagogic connectedness and revealed the ways in which teachers experience this phenomenon. Pedagogic connectedness is defined as the engagements between teacher and student that impact on student learning. In this study, twenty teachers in an independent college in South-East Queensland, Australia, were interviewed and the interview transcripts analysed iteratively. Five qualitatively different ways of experiencing pedagogic connectedness emerged from the data. The findings of this phenomenographic-related study are instructive in developing a framework for changes to teachers’ pedagogic practices.
