Weaning of Australian shortfin glass eels (Anguilla Australis): a comparison on the effectiveness of four types of fish roe

Eel culture is solely dependent on wild seed stock, caught in estuaries during the freshwater migratory phase as glass eels. The methods used for weaning glass eels are very variable, and range from the use of live zooplankton to fish roe to fines of commercial fish feeds. The present experiments were conducted on glass eels of the Australian shortfin eel, when the effectiveness of four types of readily available fish roe (European carp, mirror dory, orange roughy and warehou) were evaluated over a 42-day period, in the laboratory.

After 28 days the eels did not show an interest in orange roughy and mirror dory roe, and these two treatments were discontinued to avoid mortality. In all treatments there was a decrease in mean weight during this period, but the survival was over 99%. In the 28th to 42nd day period the mean weight and specific growth rate of glass eels reared on European carp and warehou roe increased, but the differences between these two treatments were not significant.

The physical features of the roe and the oocytes thereof, the proximate composition, amino acid and fatty acid composition indicated major differences amongst the roe types, particularly with regard to the amount of n−6 polyunsaturated fatty acids (PUFA) and the ratio of n−3 to n−6. European carp and warehou roe (and oocytes) had a significantly higher arachidonic acid (AA-20:4n−6; over 60% of PUFA) content and a considerably lower n−3 to n−6 ratio (n−3 to n−6 ratio being 1.32, 5.92, 3.77 and 2.67 for roe types, and 1.25, 4.83, 2.91 and 2.42 for oocytes, of European carp, mirror dory, orange roughy and warehou, respectively), than in the other two roe types. The fatty acid profiles of European carp and warehou roe were similar to that of metamorphosing glass eels.

Understanding Concepts of Efficiency and Effectiveness in Architectural Facilities Space Planning and Design

Although contemporary literature treats efficiency and effectiveness extensively, virtually no objective understanding of both is found in architectural facilities space planning and design. It is imperative that both concepts are definitively explained as they apply to these disciplines. Hence, the contemporary views of both concepts are reviewed and attempts made to interpret them within more amenable contexts. The objectives are (1) to objectively elucidate the factual differences between efficiency and effectiveness; and (2) to contribute to their better understanding in architectural facilities space planning and design. Diagrammatic and mathematical means are engaged to demonstrate efficiency and effectiveness in these fields.

A field test of the diversity-openness moderator model in newly formed groups: openness to diversity affects group decision effectiveness and interaction patterns

Detrimental effects of diversity in workgroups has frequently been observed but research identifying the factors that lead to negative or positive effects in heterogeneous groups is lacking. The perceived dissimilarity openness moderator model provides one explanation of the process by which diversity influences group affective, behavioral, and cognitive outcomes. Specifically the model identifies individual, group, and organizational openness as moderating the effects of diversity in workgroups. In this paper evidence is provided from a field study that increased openness to perceived dissimilarity leads to better outcomes in newly formed groups. This study also constitutes a significant building block toward the development of theory concerning the moderating variables of the relationship between diversity and group processes, and outcomes of organizations.

The effectiveness of the bills of quantities in Australia

The research aimed to explore if the information in the Australian Bill of Quantities (BOQ) was presented in a manner that could be utilized effectively by the end user. Populations surveyed; contractor, subcontractor and quantity surveyor, agree that the BOQ is a document that should be retained and would be used if produced. The adequacy of information was found to be in question by the users of the BOQ. The locational information is not adequate for its purpose. The quantities are neither located in the structure nor broken down into zones so useful for material ordering, daily work production management and cost management tasks. This information provided was requested to be supplemented by the inclusion of drawings, drawing  numbers and the zonal breakdown of quantities in a smaller number of BOQ items. End users concluded that the current information contained within the BOQ is efficient but not effective. Not one participant — quantity surveyors, contractors and subcontractors — believed they were adequately consulted or represented in production of the latest StandardMethod of Measurement (SMM). It is concluded that there is a need for end-users such as contractors and subcontractors to have greater input into the design, development and implementation of the Australian SMM. The resultant “consensus document” could then be an effective communication tool that is used for estimating, planning, purchasing and site management.

Securing institutional legitimacy or organizational effectiveness?

Purpose: The purpose of this paper is to consider the impact of a major initiative (the National Competition Policy) and pieces of legislation (the Local Government Act and the Local Government Finance Standards) on the internal practices of a large Australian local authority.

Design/methodology/approach: A theoretical framework is developed using new public management (NPM) and neo-institutional theory literatures to explain the findings. A case study approach was applied to collect the data for the research.

Findings: The findings reveal that the National Competition Policy 1993, the Local Government Act 1993 and the Local Government Finance Standards 1994 mainly have brought about significant changes to the organisation's internal management control processes, such as financial reporting, budgeting and performance appraisal. The changes brought in appeared to be coincidentally similar to NPM ideals. Furthermore, senior managers (such as the chief executive and divisional heads) played a major role in implementing new accounting technologies (activity-based costing and the balanced scorecard type performance measurement system).

Research limitations/implications: Future research on public sector financial management from the outset of organisational contexts could considerably further the stock of knowledge in this area, especially given the rapid changes occurring within the public sector throughout the world. Future research may wish to extend this study by assessing how external legitimating functions become internal reality, the perceptions of reality of the organisational members, and how these perceptions change over time.

Practical implications: The findings reported provide evidence to further our understanding of how the introduction of private sector styles of organisational practices into large areas of the public sector brought about significant changes in the demand for “new” financial management practices.

Originality/value: The findings reported on in this paper will open a new path of research that may increase our understanding about the factors that play a role in the design of management and accounting systems in a public sector context. Further, they will help policy makers and public sector managers in their day-to-day decision-making.

Piloting the feasibility and effectiveness of print- and telephone-mediated interventions for promoting the adoption of physical activity in Australian adults

This study examined the feasibility and effectiveness for increasing physical activity of a print-based intervention, and a print- plus telephone-mediated intervention among mid-life and older Australian adults. A randomised controlled trial study design was used. In mid-2002, 66 adults (18 men, 48 women) aged 45–78 years, who identified themselves as underactive, were recruited through advertisements and word-of-mouth at two sites (Melbourne and Brisbane), and randomised to either the print or print-plus-telephone mediated intervention group. Participants in both groups attended an initial briefing session, and over the 12-week intervention period received an instructional newsletter and use of a pedometer (both groups), and individualised telephone calls (print-plus-telephone group only). Self-reported physical activity data were collected at baseline, 12 and 16 weeks. Measures of self-reported global physical activity, moderate-vigorous intensity activity and walking all showed increases between baseline and 12 weeks for both intervention groups. These increases were generally maintained by 16 weeks, although participants in the print-plus-telephone group maintained slightly higher levels of global reported activity and walking (by approximately 30 mins/wk) than those in the print group. These interventions show potential for promoting initial increases in physical activity among mid-life and older Australian adults, and should be evaluated across more extended time periods.

Market research effectiveness : the effects of organisational structure, resource allocation and strategic type

According to the marketing literature and marketing textbooks, market research is required for successful marketing. However organisations differ in the way they both manage and resource their market research. This study hypothesised that market research effectiveness would be a function of internal research buying expertise, resource allocation and strategy. The research was conducted among a sample of 240 Australian marketing managers. Market research effectiveness was measured in terms of a) decision making support, b) contribution to marketing strategy, c) leveraging customer and competitor data, d) its ability to represent the "voice of the customer" and finally, e) bolstering the role of the marketing group and marketing manager within the organisation. The findings showed that having dedicated internal market researchers and allocating internal and external resources to the research function enhanced market research effectiveness. It was also found that organisations with an entrepreneurial strategic orientation were more likely to see value in the market research function, with these organisations being less likely to use market research for internal political purposes.

Aid effectiveness on accumulation: a meta study

The AEL (aid effectiveness literature) studies the macroeconomic effects of development aid using cross-country or panel data econometrics. It contains 97 papers of which 43 study whether development aid leads to increasing accumulation. The aggregate results of the 43 studies are that aid increases investment with about 25% of the aid, while most of the remaining 75% of the effect is crowded out by a fall in savings. However, these aggregate results are so variable that it is dubious if accumulation rises.

A study of organizational effectiveness for national olympic sporting organizations

This study applies the competing values approach (CVA) of organizational effectiveness to a sample of nonprofit Australian national Olympic sporting organizations (NOSOs). The purpose of the study was to determine the psychometric properties of the subscales developed within each of the four quadrants composing the CVA. Two hundred eightynine constituents from 10 NOSOs participated in this study. Initial factor analysis resulted in six of the eight theoretically derived cells in the CVAeach yielding one reliable factor. These were Flexibility, Resources, Planning, Productivity, Availability of Information, and Stability. The other two cells, Skilled Workforce and Cohesive Workforce, each produced a two-factor structure. To understand the relationship between these manifest factors (cells) and organizational effectiveness, a confirmatory factor analysis was conducted, which revealed that the rational-goal model, comprising Productivity and Planning, was the critical determinant of effectiveness in NOSOs.

Evaluating the effectiveness of public health interventions: the role and activities of the Cochrane Collaboration

Public health decision makers, funders, practitioners, and the public are increasingly interested in the evidence that underpins public health decision making. Decisions in public health cover a vast range of activities. With the ever increasing global volume of primary research, knowledge and changes in thinking and approaches, quality systematic reviews of all the available research that is relevant to a particular practice or policy decision are an efficient way to synthesise and utilise research efforts. The Cochrane Collaboration includes an organised entity that aims to increase the quality and quantity of public health systematic reviews, through a range of activities. This paper aims to provide a glossary of the terms and activities related to public health and the Cochrane Collaboration.
