There is recognition that the first-year of university study is a critical phase in the preparation, motivation and retention of science, mathematics,  engineering and technology (SMET) students. First-year provides the foundation/generic skills upon which students will base their undergraduate studies and professional practice; first-year is where many poorly prepared/at risk students will drop out and contribute to the poor student retention rate observed in the SMET disciplines; and first-year is when students may lose the motivation to pursue their chosen career direction if they find the studies at the commencement of their undergraduate program appear to bear no relationship to their intended career. In 2003, the Learning Resources Advisory Group of the Deakin University School of Engineering and Technology was requested to undertake a review of first-year units in the School’s programs. The information contained in anonymous unit evaluation questionnaires from the years 2000-2002 was used as the basis for analysing student perceptions of first-year units. In unit evaluations, students reported a wide range of issues that impacted negatively on their perception of the content and conduct of first-year units. It was noted that units service taught by other Schools form a significant element of the first-year of all of the Engineering and Technology undergraduate programs – typically 25 to 50 percent of the content. The significant influence of these units on the perceptions of the first-year of the School’s commencing students means that the School should exercise some control over the content and delivery of these units.

The research reported in this paper is part of a larger project designed to compare the online collaborative learning behaviours of Chinese Heritage Culture (CHC) university students, for whom a Chinese dialect is a first language, with Australian university students of European descent, and for whom English is a first language. The collaborative learning discussion focussed on in the research involved fellow students, rather than tutorial staff, facilitating those discussions.

The first component of the research was quantitative, comprising a questionnaire on readiness for online learning, and a quantitative analysis of student postings to a student-led collaborative problem solving task conducted online. The first component of the research (reported in Smith et at, 2005) showed no differences between the two groups in their willingness to self-manage their own learning, but did show that the CHC students were significantly less comfortable than the Australian students with online learning. Student postings to the online discussions were classified into organisational postings, social postings, and intellectual. There were substantial differences between the two groups in their patterns of online postings among those classifications, as well as differences in the length of postings made.

This paper will explore these findings in more detail through qualitative data generated through interviews with a subset of students from each group. Interview data provided further insight into the lesser comfort with e-learning among CHC students. Students from both groups felt there were inefficiencies in the online discussion, but CHC students also felt rather marginalised by the process. Australian students were more likely to evaluate the experience in terms of its capacity to achieve required learning outcomes in a time efficient way, while CHC students expressed more concern about how the process had impacted upon them personally. The interview data also indicated that a tutor sensitive to cultural difference is important for comfort among the CHC students in particular, since there is need for encouragement to those students to make reflective inputs to the discussion.

The concept of blended learning, defined in a range of ways, has begun to change the nature of all teaching and learning in higher education. Information and communication technologies have impacted by providing a means of access to digital resources and interactive communication for all courses and the blending of pedagogy and technology has produced a range of approaches to teaching and learning. This paper will investigate reported studies from both research literature and from the writers' research, defining what they have concluded are teaching practices that use the concept of blended learning effectively.

Downsizing and organisational restructuring have impacted both the role and the number of middle managers in organisations. .This paper provides a review of recent research on middle management to seek an understanding of the current situation for middle managers as they face the start of the 2rt century. The literature review is presented in two parts - focusing on the position of middle managers as they emerge from downsizing, and drawing attention to the special circumstances for managers "in the middle". The research points to some of the challenges middle managers' experience as they work, live, and survive organisational life, as well as highlighting the need for ongoing investigation of their individual experiences.

This paper poses the question, what impact have student evaluations (SE’s) of teaching had on the improvement in teaching in Australian tertiary education. The paper proposes to assess the effectiveness of SE’s through an investigations of the ways in which have been used in Australian tertiary education over the last 20 years or so. Three approaches are discussed: a) quality assurance - student evaluations used to ensure the quality of the learning environment in which learning takes place; b) quality improvement - student evaluations used as a diagnostic tool for individual teaching staff; and c) student feedback – student evaluations used to provide prospective and current students with information to help inform their choices and expectations. The discussions reviews some of the research and known practise in Australian universities. It concludes that SE’s have had a profound impact on pedagological understandings of tertiary education by placing the student at centre stage of teaching and learning. However it suggests that we do not know how SE’s have impacted on teaching effectiveness and improvement. The paper concludes by recommending further research to define critical success factors, a better understanding of how to make the student feedback and evaluation tools and mechanisms more approachable and meaningful for students, and an assessment of the ‘survey industry’ as a sustainable enterprise.

Purpose – This study aims to understand buyer and supplier motives for developing direct relationships with their trade partners.

Design/methodology/approach – A total of 18 in-depth interviews were conducted across Victoria and Tasmania (Australia); eight with retail buyers and ten with fresh produce suppliers. Both parties were involved in a direct relationship with their trade partner.

Findings – The research reveals a large variety of motivations that influence buyers and suppliers when deciding whether to operate in a direct or non-direct relationship with their trade partner. Motivations for both parties are remarkably similar, with buyers and suppliers ultimately attempting to minimise the inherent risk associated with operating in a volatile environment.

Research limitations/implications – The study may be limited by the fact that buyers and suppliers of different commodities were included in the study. In addition, the varied nature of the respondents' role may have impacted their judgment. The inability to interview dyads in all cases also limits the research.

Practical implications – This research has implications for both researchers and practitioners already involved in, or considering becoming involved in, a direct trade relationship. Clarification of motivations for bypassing intermediaries shows how both trade partners can minimise external risk and strengthen competitive advantage by assuming a direct relationship.

Originality/value – Extant research within this literary field is largely quantitatively based with researchers focusing on distinct relationship constructs, the definition of relationship marketing and the process of relationship development. In response to these limitations, this research adopted a qualitative approach in examining the core motivations for developing a direct trade relationship within the fresh produce industry.

1.For air-breathing animals in aquatic environments, foraging behaviours are often constrained by physiological capability. The development of oxygen stores and the rate at which these stores are used determine juvenile diving and foraging potential.
2. We examined the ontogeny of dive physiology in the threatened Australian sea lion Neophoca cinerea. Australian sea lions exploit benthic habitats; adult females demonstrate high field metabolic rates (FMR), maximize time spent near the benthos, and regularly exceed their calculated aerobic dive limit (cADL). Given larger animals have disproportionately greater diving capabilities; we wanted to determine the extent physiological development constrained diving and foraging in young sea lions.
3. Ten different mother/pup pairs were measured at three developmental stages (6, 15 and 23 months) at Seal Bay Conservation Park, Kangaroo Island, South Australia. Hematocrit (Hct), haemoglobin (Hb) and plasma volume were analyzed to calculate blood O2 stores and myoglobin was measured to determine muscle O2. Additionally, FMR's for nine of the juveniles were derived from doubly-labelled water measurements.
4. Australian sea lions have the slowest documented O2 store development among diving mammals. Although weaning typically occurs by 17·6 months, 23-month juveniles had only developed 68% of adult blood O2. Muscle O2 was the slowest to develop and was 60% of adult values at 23 months.
5. We divided available O2 stores (37·11 ± 1·49 mL O2 kg−1) by at-sea FMR (15·78 ± 1·29 mL O2 min−1 kg−1) to determine a cADL of 2·33 ± 0·24 min for juvenile Australian sea lions. Like adults, young sea lions regularly exceeded cADL's with 67·8 ± 2·8% of dives over theoretical limits and a mean dive duration to cADL ratio of 1·23 ± 0·10.
6. Both dive depth and duration appear impacted by the slow development of oxygen stores. For species that operate close to, or indeed above their estimated physiological maximum, the capacity to increase dive depth, duration or foraging effort would be limited. Due to reduced access to benthic habitat and restricted behavioural options, young benthic foragers, such as Australian sea lions, would be particularly vulnerable to resource limitation.

This study tracked the movements of Australian sea lion (Neophoca cinerea) pups, juveniles, and adult females to identify home ranges and determine if young sea lions accompanied their mothers at sea. Satellite tags were deployed on nine 15- mo-old pups, nine 23-mo-old juveniles, and twenty-nine adult female Australian sea lions at Seal Bay Conservation Park, Kangaroo Island, South Australia. Females did not travel with their offspring at sea, suggesting young Australian sea lions learn foraging behaviors independently. Although home ranges increased with age,  23-mo-old juveniles had not developed adult movement capacity and their range was only 40.6% of the adult range. Juveniles traveled shorter distances (34.8 ± 5.5 km) at slower speeds (2.0 ± 0.3 km/h) than adults (67.9 ± 3.5 km and 3.9 ± 0.3 km/h). Young sea lions also stayed in shallower waters; sea floor depths of mean locations were 48±7m for juveniles and 74±2m for females. Restricted to shallow coastal waters, pups and juveniles are more likely to be disproportionately impacted by human activities. With limited available foraging habitat, young Australian sea lions appear particularly vulnerable to environmental alterations resulting from fisheries or climate change.

The concept of blended learning has begun to change the nature of all teaching and learning in higher education. Information and communication technologies have impacted by providing a means of access to digital resources and interactive communication for all courses and the blending of pedagogy and technology has produced a range of approaches to teaching and learning. This paper discusses the research literature and the writers’ research, defining what they have concluded are teaching practices that use the concept of blended learning effectively. In investigating how ICT can add variation for student learning, they analyze this from two dominant modes of pedagogy, learning environment and pedagogy through both on-campus and distance education. In both modes, students acknowledged the power and effectiveness of blended learning.

The National Australia Bank (NAB), one of Australia's largest banks, announced losses in 2004 of AUD$360 million due to unauthorised foreign currency trading activities by four employees who incurred and deceptively concealed the losses. The NAB had in place risk limits and supervision to prevent trading desks ever reaching positions of this magnitude. However, the risk management policies and procedures proved ineffective. The purpose of this paper is to analyse the deceit, via a content analysis of official investigative reports and other published documents, to determine the extent to which the Bank's culture and leadership may have influenced the rogue traders' behaviour. The findings suggest that cultural issues, and the role played by the Bank's leaders, were influential in creating a profit-driven culture that ultimately impacted the Bank's foreign exchange operating activities.

Sewage effluent is a powerful agent of ecological change in estuaries. While the effects of sewage pollution on water quality are usually well documented, biological responses of exposed organisms are not. We quantified health impacts in the form of pathological tissue changes across multiple organs in estuarine fish exposed to elevated levels of treated wastewater. Structural pathologies were compared in wild populations of four fish species from two subtropical estuaries on the east coast of Australia that differ substantially in the amount of direct wastewater loadings. Uptake of sewage-derived  nitrogen by fish was traced with stable nitrogen isotopes. Pathologies were common in the liver, spleen, gill, kidney and muscle tissues, and included granulomas, melanomacrophage aggregates, and multiple deformities of the gill epithelia. Tissue deformities were more frequent in fish exposed directly to wastewater discharges. Mullet (Valamugil georgii) were most affected, with only a single specimen free of pathologies in the sewage-impacted estuary. Similarly, in those fish that had structural abnormalities, more deformities were generally found in individuals from sites receiving sewage. These spatial contrasts in impaired fish health correspond to significantly enriched δ15N values in fish muscle as a consequence of fish assimilating sewage-N. Overall, the pattern of lower health and enriched δ15N values in fish from sewage-impacted areas suggests that organism health is lowered by sewage inputs to estuaries. Measurements of organism health are required to understand the effects of sewage on estuarine ecosystems, and histopathology of fishes is a powerful tool to achieve this.

In this paper I focus on a neglected aspect of Australian political history, the extent to which Australian governments actually redistributed income. The German sociologist Rudolf Goldscheid argued that 'the budget is the skeleton of the state stripped of all misleading ideologies'. In Australia a party that claimed to represent lower income earners, the Labor Party, was a major political force, but did Labor actually make a difference to the distribution of income across social classes, or did Labor's rhetoric of equity merely serve to incorporate workers into the capitalist system? A quantitative approach to the political history of labour may enable us to escape both nostalgia for old labourism (which the Howard years have encouraged) and a simple and undifferentiated rejection of labourism as a reformist agent of social integration.

This paper incorporates some material from a 2005 paper that examined overall expenditure patterns and taxation patterns across the states and Commonwealth from 1910 to 1940 but it goes beyond the aggregate approach of this paper to consider the extent which the varying patterns of taxation and public expenditure across Australia impacted on different social classes during the 1930s. It is very much a preliminary analysis based on existing compilations of taxation statistics. It is a static analysis and does not consider if nominally redistributive taxation and expenditure patterns might be rendered ineffective by consequent interstate migration.

Auditors were criticised during and after the Asian economic crisis for supplying variable quality across global audit markets. This study examines
the level of earnings management as measured by discretionary accruals in the pre-crisis compared to the post-crisis periods as they impacted Malaysia. Both the Jones (1991) and earnings per share frequency distribution methods are used to examine earnings management behaviour. As hypothesised, the pre-crisis period is associated with significantly higher levels of absolute discretionary accruals and increased propensity to meet or beat the prior year earnings per share, whereas the post-crisis period is not. This finding is consistent with auditors responding to the criticisms that were made. However, the propensity to avoid losses is found to be higher in the post-crisis period, indicating that earnings management is not fully constrained.

In recent years museums have changed from being predominantly custodial institutions to becoming increasingly focussed on audience attraction. New emphasis is placed on museum-audience interactions and relationships. This change in the purpose and priorities of museums has impacted upon the nature of museum management. The recognition of new roles for museum directors and the need to appeal to differentiated audiences has created new challenges for previously traditional, custodial directors. This paper presents a conceptual framework for managing museums, taking account of the museum service context and the delivery of the museum service product. It then examines two museums, one in Ireland and one in Australia, both of which have a similar cultural history. The paper considers the different management styles for museum directors and how these different styles illustrate the changes in professional perspective from the traditional (a focus on custodial preservation) to the more current (a focus on educating and entertaining the public).

The extent to which legislation and special education policy have impacted on the nature of the educational enrolment of students with a disability in Australia has not been clearly addressed. Although there are no detailed and systematic national data on the enrolment of students with a disability in inclusive settings, special classes and special schools in Australia, some broad trends are apparent. The legislative background to these trends is discussed. As might be expected, there are variations in the nature of the educational enrolment of students with a disability across the states and territories of Australia. Enrolment trends in the two most populous states, New South Wales and Victoria, are examined and discussed within the context of their respective special education policies, disability discrimination legislation, and educational precedent.
