Dynamic Characteristics Of A Hybrid Microgrid With Inverter And Non- Inverter Interfaced Renewable Energy Sources: A Case Study, A V. Jayawardena, L G. Meegahapola, S Perera, D A. Robinson Dec 2013

Dynamic Characteristics Of A Hybrid Microgrid With Inverter And Non- Inverter Interfaced Renewable Energy Sources: A Case Study, A V. Jayawardena, L G. Meegahapola, S Perera, D A. Robinson

Dr Lasantha G Meegahapola

Microgrids are becoming important constituents of electric power distribution networks. Microgrids are typically comprised of both inverter interfaced (e.g. double-fed induction generator (DFIG), solar-photovoltaic (PV) system) and non-inverter interfaced (e.g. synchronous generator) renewable energy generators (REGs), hence their dynamic characteristics are significantly different from the conventional grids comprised of centralised synchronous generators. Different inherent characteristics of REGs, power dispatch levels, relative REG capacities, and external grid characteristics are some of the important features of significant interest in relation to microgrid dynamic behaviour. For this study a microgrid model was developed in DIgSILENT Power Factory based on the IEEE-13 bus system …


Making Things In A High-Dollar Australia: The Case Of The Surfboard Industry, Andrew Warren, Chris Gibson Nov 2013

Making Things In A High-Dollar Australia: The Case Of The Surfboard Industry, Andrew Warren, Chris Gibson

Chris Gibson

In August 2011 the announcement by Bluescope Steel of mass layoffs at its Port Kembla steelworks, in the Illawarra region, sparked renewed public debate and media commentary on the future of manufacturing in Australia. The debate has since spread to cars, aluminium smelting - even Mortein fly spray - and has quickly coalesced around the unprecedented high Australian dollar, its impacts on exports, and the prospects of the production of goods shifting overseas. As Australian mining magnates such as Clive Palmer, Gina Rinehart and Twiggy Forrest attempt to remould Australia around their 'quarry vision' (Pearse, 2009) of extractive minerals exports, …


A Taxonomy For Homework Used By Mental Health Case Managers When Working With Individuals Diagnosed With Severe Mental Illness, Peter Kelly, Frank P. Deane, Robert King, Nikolaos Kazantzis, Trevor P. Crowe Jul 2013

A Taxonomy For Homework Used By Mental Health Case Managers When Working With Individuals Diagnosed With Severe Mental Illness, Peter Kelly, Frank P. Deane, Robert King, Nikolaos Kazantzis, Trevor P. Crowe

Peter Kelly

A survey was completed by 122 case managers describing the types of homework assignments commonly used with individuals diagnosed with severe mental illness (SMI). Homework types were categorized using a 12-item homework description taxonomy and in relation to the 22 domains of the Camberwell Assessment of Need (CAN). Case managers predominately reported using behaviourally based homework tasks such as scheduling activities and the development of personal hygiene skills. Homework focused on CAN areas of need in relation to Company, Psychological Distress, Psychotic Symptoms and Daytime Activities. The applications of the taxonomy for both researchers and case managers are discussed.


Macroeconomic Determinants Of Corporate Performance And Failure: Evidence From An Emerging Market The Case Of Jordan, Rami Zeitun, Gary Tian, Steve Keen Jun 2013

Macroeconomic Determinants Of Corporate Performance And Failure: Evidence From An Emerging Market The Case Of Jordan, Rami Zeitun, Gary Tian, Steve Keen

Gary Tian

This study investigates the impact of aggregate economic risk on a company’s performance and failure in a panel estimation using 167 Jordanian companies during 1989-2003. Our finding shows that unanticipated changes in interest rate negatively and significantly affect firms’ performance measured by ROA, which suggests that an interest rate rise increases the cost of borrowing and then further negatively affects a firm’s profit. We also found that both the production manufacturing index and Islamic credit facilities positively and significantly affect a firm’s performance. The positive and significant impact of Islamic credit facilities reflects the importance and the significance of the …


A Review Of Consumer Involvement In Evaluations Of Case Management: Consistency With A Recovery Paradigm, Sarah L. Marshall, Trevor P. Crowe, Lindsay G. Oades, Frank F. Deane, David J. Kavanagh Feb 2013

A Review Of Consumer Involvement In Evaluations Of Case Management: Consistency With A Recovery Paradigm, Sarah L. Marshall, Trevor P. Crowe, Lindsay G. Oades, Frank F. Deane, David J. Kavanagh

Lindsay G Oades

This Open Forum examines research on case management that draws on consumer perspectives. It clarifies the extent of consumer involvement and whether evaluations were informed by recovery perspectives. Searches of three databases revealed 13 studies that sought to investigate consumer perspectives. Only one study asked consumers about experiences of recovery. Most evaluations did not adequately assess consumers' views, and active consumer participation in research was rare. Supporting an individual's recovery requires commitment to a recovery paradigm that incorporates traditional symptom reduction and improved functioning, with broader recovery principles, and a shift in focus from illness to well-being. It also requires …


An Activity Theory Analysis Of A Case Of It-Driven Organisational Change, Wannapa Suratmethakul, Helen Hasan Feb 2013

An Activity Theory Analysis Of A Case Of It-Driven Organisational Change, Wannapa Suratmethakul, Helen Hasan

Helen Hasan

The paper describes unexpected problems encountered in the automation of a scheduling process using an IT application already in use in other similar organisations. A grounded theory approach was used to collect and categorise data on the case. Activity Theory was then used to analyse the attempt by management to implement organisational change through the introduction of the system. The findings suggest that it is inadvisable to impose organisational change through the introduction of a complex IT system, particularly when this disrupts entrenched decision-making processes of the organisation.
