Full textAbstract:
Demand forecasting has a pivotal role in making informed business decisions by predicting future sales using historical data. Traditionally, demand forecasting has been widely used in the management of production, staffing and warehousing for sales and marketing data. However, the use of demand forecasting has little been studied in the container shipping industry. Improved visibility into the demand for container shipments has been a long-held objective of industry stakeholders. This paper addresses the shortcomings of both short-term and long-term shipment demand forecasting for the Australian container shipping industry. In this study, we compare three forecasting models, namely, the seasonal auto-regressive integrated moving average (SARIMA), Holt–Winters’ seasonal method and Facebook’s Prophet, to find the best fitting model for short-term and long-term import demand forecasting in the Australian shipping industry. Demand data from three years, i.e., 2016–2018, is used for the Asia–Oceania trade lane. The mean absolute percentage error (MAPE), root mean squared error (RMSE) and 2-fold walk-forward cross-validation are used for the model evaluation. The experiment results observed from the selected metrics suggest that Prophet outperforms the other models in its comparison for container shipment demand forecasting.

Full textAbstract:
Purpose The purpose of this study is to explore warehouse configuration in omni-channel retailing. Design/methodology/approach A multiple case study is conducted with six large omni-channel retailers from three different sectors. Findings The study shows an increase in the number, variation and frequency of flows passing through omni-channel warehouses. Along with an increased variety of stock keeping units (including singles vs multipacks), there is an increase in the complexity of planning and coordination of order fulfillment. Retailers test a mix of different solutions for storage and picking and partly shift focus to advanced sorting operations. The companies already have or plan to invest in substantial automation systems, which emphasize the importance of capturing and using accurate master data. Research limitations/implications The study highlights the need to understand the interrelations and co-development of configuration elements in omni-channel warehousing. The findings also suggest that a successful transformation requires increased collaboration with upstream and downstream partners. Conceptual models are developed to illustrate strategies and development paths in omni-channel warehousing, and suggestions for future research are summarized in a research agenda. A research limitation is the focus on Swedish retailers in three sectors (fashion, consumer electronics and DIY/construction material). Future studies can include additional sectors, extend the geographical scope and explore cross-regional differences. Practical implications As one of the few deeper case studies on omni-channel warehousing, practitioners will find new configurations described and analyzed here. Along with conceptual models, a synthesis of challenges and potential solutions are presented to support retailers’ practical analysis and decision making. Originality/value This is one of the first multiple case studies that go deeper into omni-channel warehouse configuration, which is of increasing importance to both scholars and practitioners in the field.

Purpose – Logisticians in the worldwide industry are frequently faced with the problem of measuring the total cost of holding inventories with simple and easy-to-use methodologies. The purpose of this paper is to look at the problem, and in particular illustrate the inventory holding cost rate computation, when different kind of warehousing systems are applied. Design/methodology/approach – A multiple case study analysis is here developed and supported by a methodological framework directly derived from the working group discussions and brainstorming activities. Two different field of application are considered: one related to five companies with manual warehousing systems operating with traditional fork lift trucks; the other is among five companies operating with automated storage/retrieval systems (AS/RS) to store inventories. Findings – The multi-case study helps to understand how the holding cost parameter is currently computed by industrial managers and how much the difference between manual and automated/automatic warehousing systems impacts on the inventory cost structure definition. The insights from the ten case studies provide evidence that the kind of storage system adopted inside the factory can impact on the holding cost rate computation and permit to derive important considerations. Practical implications – The final aim of this work is to help industrial engineers and logisticians in correctly understanding the inventory costs involved in their systems and their cost structure. In addition, the multi-case analysis leads to considerations, to be applied in different industrial contexts. As other industrial applications are identified, they may be analyzed by using the presented methodology, and with aid from the data from this paper. Originality/value – The relevance of this work is to help industrial engineers and logisticians in understanding correctly the inventory costs involved in their logistics systems and their cost structure. In addition, the multi-case analysis lead to interesting final considerations, easily to be applied in different industrial contexts. As other industrial applications are identified, they may be analyzed by using the methodology and extrapolating the data from this paper.

Full textAbstract:
Objective The aim of the present study was to identify all evidence about the prevalence and severity of clinically measured caries and periodontal disease in Indigenous adults in Australia published in peer-reviewed journals and to summarise trends over time. In addition, we examined whether the studies investigated associations between putative risk factors and levels of caries and periodontal disease. Methods PubMed was searched in September 2014, with no date limitations, for published peer-reviewed articles reporting the prevalence rates and/or severity of caries and periodontal disease in Indigenous adults living in Australia. Articles were excluded if measurement was not based on clinical assessment and if oral disease was reported only in a specific or targeted sample, and not the general population. Results The search identified 18 papers (reporting on 10 primary studies) that met the inclusion criteria. The studies published clinical data about dental caries and/or periodontal disease in Australian Indigenous adults. The studies reported on oral health for Indigenous adults living in rural (40%), urban (10%) and both urban and rural (50%) locations. Included studies showed that virtually all Indigenous adults living in rural locations had periodontal disease. The data also showed caries prevalence ranged from 46% to 93%. Although 10 studies were identified, the peer-reviewed literature was extremely limited and no published studies were identified that provided statistics for a significant proportion of Australia (Victoria, Tasmania, Queensland or the Australian Capital Territory). There were also inconsistencies in how the data were reported between studies, making comparisons difficult. Conclusions This review highlights a lack of robust and contemporary data to inform the development of policies and programs to address the disparities in oral health in Indigenous populations living in many parts of Australia. What is known about the topic? Many studies report that Indigenous people in Australia have poorer general health compared with non-Indigenous people. What does this paper add? This paper documents the available caries and periodontal disease prevalence and experience for Indigenous adults in Australia published in peer-reviewed journals. It demonstrates significant limitations in the data, including no data in several large Australian jurisdictions, inconsistency with reporting methods and most data available being for Indigenous adults living in rural locations. Therefore, the oral health data available in the peer-reviewed literature do not reflect the situation of all Indigenous people living in Australia. What are the implications for practitioners? It is important for oral health practitioners to have access to current and relevant statistics on the oral health of Indigenous Australians. However, we have highlighted significant evidence gaps for this population group within the peer-reviewed literature and identified the limitations of the available data upon which decisions are currently being made. This paper also identifies ways to capture and report oral health data in the future to enable more meaningful comparisons and relevance for use in policy development.

Full textAbstract:
In qualitative methods, there are various approaches that can be used to answer particular social questions, for example ethnography and case study. Two studies conducted by different researchers in China and Australia using these approaches were described and analysed in order to find out their similarities and differences in terms of philosophical and methodological perspectives, in the hope that it will provide an insightful contribution to a critical review of ethnography and case study reports. It is found that the ethnograpic study in China was clasiffied in ethnographic fieldwork, whereas the case study conducted in Australia was categorised in explanatory, multi-cases study. Furthermore, these two studies produced different knowledge within the field of education. The first study revealed that basic education were related to literacy, numeracy, and cultural characteristics of China, whereas the study conducted in Australia offered statistical data that can be used to explain minority languages maintenance program in Wollongong-Shellharbour. In relation to their methodoligal practices, however, focus group discussion and interview conducted in Zhejiang Province, China produced irrelevant data and those had been held in Wollongong, Australia, had limited participants.

Full textAbstract:
The determination of the Islamic calendar is paramount in Islam because it strongly relates to worship, like Ramadan fasting, eid-al-fitr, and zakat fitr. Many studies have examined young moon visibility criteria in many Muslim countries, such as Indonesia, Saudi Arabia, Thailand, and Singapore. However, no study on the initiation of the Islamic month has been conducted in Australia, a Muslim-minority country with middle-eastern immigrants seeking jobs. One of Australia's most trusted organizations to announce the start of Hijri month is Moonsighting Australia. Therefore, this study aimed to analyze the determination of the Islamic calendar by Moonsighting Australia organization based on factors such as method, matla, rukyat time, hilāl visibility, and resistors (1 Dzulhijjah 1441 H). A descriptive study with a qualitative approach used literature reviews, content analysis, and case studies. Primary data were taken from a decision letter from Moonsighting Australia about the start of Dzulhijjah 1441 H, interviews with the coordinator, and relevant references. The findings showed that Moonsighting Australia applies a rukyat method by the naked eye - without any optical aids and hilāl visibility criteria consideration - every 29th of Hijri month. Also, it tunes the concept of matla wilayat al hukmi, where the sighting process and result are implemented throughout Australia’s territory.
Keywords: Australia, Dzulhijjah, Hijri, Islamic Month, Moonsighting.

Full textAbstract:
Sixteen wireless case studies highlight issues relating to mobile commerce in Australia. The issues include: the need for a clear business case; difficulty of achieving critical mass and acceptance of a new service; training and technical issues, as well as staff acceptance issues; that privacy and security issues arise through the potential to track the location of people and through the amounts of personal data collected; difficulties in integrating with existing back-end systems; projects being affected by changes to legislation, or requiring changes to the law; and that while there is potential for mobile phone operators to develop new billing methods that become new models for issuing credit, they are not covered by existing credit laws. We have placed the case studies in a Fit-Viability framework and analyzed the issues according to key success criteria. While many organizations are keen to use the technology, they are struggling to find a compelling business case for adoption and that without a strong business case projects are unlikely to progress past the pilot stage.

Full textAbstract:
Two major collecting institutions in Australia, the Australian Museum (Sydney) and Museums Victoria (Melbourne), are currently undertaking large-scale anoxic rehousing projects in their collections to control conservation issues caused by pyrite oxidation. This paper will highlight the successes and challenges of the rehousing projects at both institutions, which have collaborated on developing strategies to mitigate loss to their collections. In 2017, Museums Victoria Conservation undertook a survey with an Oxybaby M+ Gas Analyser to assess the oxygen levels in all their existing anoxic microclimates before launching a program to replace failed microclimates and expand the number of specimens housed in anoxic storage. This project included a literature review of current conservation materials and techniques associated with anoxic storage, and informed the selection of the RP System oxygen scavenger and Escal Neo barrier film from Mitsubishi Gas Chemical Company as the best-practice products to use for this application. Conservation at the Australian Museum in Sydney was notified of wide-scale pyrite decay in the Palaeontology and Mineral collections. It was noted that many of the old high-barrier film enclosures, done more than ten years ago, were showing signs of failing. None of the Palaeontology specimens had ever been placed in microclimates. After consultation with Museums Victoria and Collection staff, a similar pathway used by Museums Victoria was adopted. Because of the scale of the rehousing project, standardized custom boxes were made, making the construction of hundreds of boxes easier. It is hoped that new products, like the tube-style Escal film, will extend the life of this rehousing project. Enclosures are being tested at the Australian Museum with a digital oxygen meter. Pyrite rehousing projects highlight the loss of Collection materials and data brought about by the inherent properties of some specimens. The steps undertaken to mitigate or reduce the levels of corrosion are linked to the preservation of both the specimens and the data kept with them (paper labels). These projects benefited from the collaboration of Natural Sciences conservators in Australia with Geosciences collections staff. Natural Science is a relatively recent specialization for the Australian conservation profession and it is important to build resources and capacity for conservators to care for these collections. This applied knowledge has already been passed on to other regions in Australia.

Full textAbstract:
This paper presents a new approach to content-based image retrieval by using dynamic indexing and guided search in a hierarchical structure, and extending data mining and data warehousing techniques. The proposed algorithms include a wavelet-based scheme for multiple image feature extraction, the extension of a conventional data warehouse and an image database to an image data warehouse for dynamic image indexing. It also provides an image data schema for hierarchical image representation and dynamic image indexing, a statistically based feature selection scheme to achieve flexible similarity measures, and a feature component code to facilitate query processing and guide the search for the best matching. A series of case studies are reported, which include a wavelet-based image color hierarchy, classification of satellite images, tropical cyclone pattern recognition, and personal identification using multi-level palmprint and face features. Experimental results confirm that the new approach is feasible for content-based image retrieval.

In spite of the lack of supporting research data, those responsible for education throughout Australia at both federal and state levels have released policies on integration; and there is a trend towards moving students with disabilities out of special education facilities into regular school settings. This paper reviews the findings of Australian research on integration, identifies deficiencies, and points to future directions that research might take if integration is to proceed with the backing of relevant data. A major deficiency is seen in available statistical information, so that it is difficult to estimate the real impact of integration on education systems. Although studies so far reveal some success in integration of disabled students, this depends on individual characteristics, on early educational experiences, and on the provision of support services in the school. Attitudes of school staff are generally positive towards the concept of integration, but this is conditional on the availability of adequate resources and support. Several areas for future research are identified, including longitudinal research, individual case studies, and action-based projects.

Full textAbstract:
This article explores images of young children in preschool music curricula in an Australian and a Chinese preschool. The ‘images of the child’ relevant to each country are presented by including children’s voices, teachers’ perceptions of children’s personalities and their ways of learning, and children’s roles in learning as designated in official documents on early childhood education. Framed by a sociocultural perspective, this qualitative case study responds to the changing contexts of early childhood music education (ECME) in both countries. Crystallization as a methodological lens is applied to shed light on the variations and complexities from the teachers’ and the children’s perspectives. Data-gathering methods include document analysis, classroom observations, teachers’ interviews and conversations with children. This article particularly reflects the images and experiences of the children through their own lenses and enriches the scope of current ECME research.The main findings suggest the existence of both alignment and gaps, in varying degrees, between the official policy documents, the teachers’ perceptions, and the children’s understandings of their musical experiences. First, images of the child in the policy articles are interpreted differently in Australia and China, and there is a marked difference between the countries in their definitions of child-centred learning in specific contexts. Finally, implications and directions for future research are suggested to facilitate children’s musical exploration in preschools.

Australia is a country firmly part of the Global North, yet geographically located in the Global South. This North-in-South divide plays out internally within Australia given its status as a British settler-colonial society which continues to perpetrate imperial and colonial practices vis-à-vis the Indigenous peoples and vis-à-vis Australia’s neighboring countries in the Asia-Pacific region. This article draws on and discusses five seminal examples forming a case study on Australia to examine big data practices through the lens of Southern Theory from a criminological perspective. We argue that Australia’s use of big data cements its status as a North-in-South environment where colonial domination is continued via modern technologies to effect enduring informational imperialism and digital colonialism. We conclude by outlining some promising ways in which data practices can be decolonized through Indigenous Data Sovereignty but acknowledge these are not currently the norm; so Australia’s digital colonialism/coloniality endures for the time being.

Abstract Germany is currently developing a marine data infrastructure addressing different topics such as coastal engineering, hydrography and surveying, protection of the marine environment, maritime conservation, regional planning, and coastal research. This undertaking is embedded in a series of regulations and developments at many administrative levels, from which specifications and courses of action are derived. To set up a conceptual framework for the marine data infrastructure of Germany (MDI-DE), scientists at the Chair for Geodesy and Geoinformatics at the Rostock University are building a reference model, evaluating meta-information systems and developing models to support common workflows in marine applications. Evaluating how other countries built their marine spatial infrastructures is important to learn where obstacles and errors are likely to occur. To be able to look at other initiatives from a neutral point of view, it is necessary to construct a framework for evaluating marine spatial data infrastructures (MSDI). This framework is then used to analyse and evaluate the efforts of Canada, Australia, and Ireland with respect to marine data infrastructures.

Full textAbstract:
Abstract Recent advances in the collection and analysis of paleoclimate data have provided significant insights into preinstrumental environmental events and processes, enabling a greater understanding of long-term environmental change and associated hydroclimatic risks. Unfortunately, it is often the case that there is a dearth of readily available paleoclimate data from regions where such insights and long-term data are most needed. The Murray–Darling basin (MDB), known as Australia’s “food bowl,” is an example of such a region where currently there are very limited in situ paleoclimate data available. While previous studies have utilized paleoclimate proxy records of large-scale climate mechanisms to infer preinstrumental MDB hydroclimatic variability, there is a lack of studies that utilize Australian terrestrial proxy records to garner similar information. Given the immediate need for improved understanding of MDB hydroclimatic variability, this paper identifies key locations in Australia where existing and as yet unrealized paleoclimate records will be most useful in reconstructing such information. To identify these key locations, rainfall relationships between MDB and non-MDB locations were explored through correlations and principal component analysis. An objective analysis using optimal interpolation was then used to pinpoint the most strategic locations to further develop proxy records and gain insights into the benefits of obtaining this additional information. The findings reveal that there is potential for the future assembly of high-resolution paleoclimate records in Australia capable of informing MDB rainfall variability, in particular southeast Australia and central-northern Australia. This study highlights the need for further investment in the development of these potential proxy sources to subsequently enable improved assessments of long-term hydroclimatic risks.

This study serves to clarify the current status of canid and felid Ancylostoma species present in Australia. The morphological identification of A. ceylanicum from cats for the first time in Townsville, Australia, appears to be in error, together with the genetic markers provided for the species. Morphological and genetic data presented herein provide strong evidence that the hookworms from cats in Towsville are not A. ceylanicum as previously identified (i.e. the first report of this species in Australia), but are A. braziliense. Therefore the subsequent genetic markers established for A. ceylanicum in subsequent molecular studies based on these Townsville specimens should also be attributed to A. braziliense. Based on this information, a study of canine hookworm species present in northern India is also in error and it is apparent that the hookworms found in this region are those of A. ceylanicum. The distribution of A. braziliense and A. ceylanicum in the Americas and Asia Pacific region is discussed together with the importance of combining parasite morphology with genetic data for parasite diagnosis in epidemiological studies.

Full textAbstract:
Abstract The aim of this article is to analyse appropriateness and adequacy of use of Data Envelopment Analysis (DEA) in several research papers dealing with effectiveness of economy of universities. The Data Envelopment Analysis is an interesting method used for evaluation of technical efficiency of production units. Comparison is the basic method of this article. At the beginning, basic methodological questions of measurement and evaluation of efficiency are analysed, including definitions of terms efficiency and effectiveness, ways of measurement and formulation of appropriate indicators. Based on the given perquisites for measurement and evaluation of efficiency five articles on evaluation of efficiency of universities using DEA method, published in Canada, Australia, Great Britain, Germany and Spain in 1998 - 2008, will be assessed. DEA is able to use more parameters of input and output to evaluate which of units under examination is the most effective, and to compare other units with it. For this, it is necessary to have a homogenous group of units. The result of assessment shows that all the examined studies focused rather on way of calculation then the point and reason of measurement. The articles contain a discussion concerning choice of appropriate indicators but do not at all deal with the issue of its construction using interventional logic; the articles do not contain any comparison of objectives of the particular universities. Evaluation of efficiency of universities is a social construct and it will always be a subjective matter related to objectives of a particular stakeholder. This fact explains how to approach the evaluation of efficiency: it is necessary to set an objective function that means to set the objectives of a given stakeholder and his preferred results and outputs. All the studies lack this basic logic.

Full textAbstract:
In this study, we attempt to expand tropical cyclone (TC) risk assessment methodology and build an understanding of TC risk to Australia’s natural environment by focusing on coral reefs. TCs are natural hazards known to have the potential to bring destruction due to associated gale-force winds, torrential rain, and storm surge. The focus of TC risk assessment studies has commonly centred around impacts on human livelihoods and infrastructure exposed to TC events. In our earlier study, we created a framework for assessing multi-hazard TC risk to the Australian population and infrastructure at the Local Government Area level. This methodology is used in this study with coral reefs as the focus. TC hazard, exposure, and vulnerability indices were created from selected coral-related datasets to calculate an overall TC risk index for the Ningaloo Reef (NR) and the Great Barrier Reef (GBR) regions. The obtained results demonstrate that the northern NR and the southern GBR had the highest risk values within the study area; however, limitations in data quality have meant that results are estimates at best. The study has shown the potential benefits of such a TC risk assessment framework that can be improved upon, as coral data collection becomes more readily available.

Full textAbstract:
The cornerstone of the capital asset pricing model (CAPM) lies with its beta. The question of whether or not beta is dead has attracted great attention from academics and practitioners in the last 50 years or so, and the debate is still ongoing. Many empirical studies have been conducted to test the validity of beta within the framework of CAPM. However, it is a claim of this paper that beta at the industry level has been largely ignored in the current literature. This study is conducted to examine if beta, proxied for a systematic risk, should be considered valid in the application of the CAPM at the industry level for Australia using daily data on 2200 stocks listed on the Australian Securities Exchange from January 2007 to 31 December 2016. Various portfolio formations are utilized in this paper. General economic conditions such as interest rate, inflation, and GDP are examples of systematic risk. Findings from this study indicate that the selection of portfolio construction, estimation technique, and news about economic conditions significantly affects the view whether or not beta should be considered as a valid measure of systematic risk.

Abstract Purpose This study aimed to document the ways by which missing data were handled in clinical pharmacy research to provide an insight into the amount of attention paid to the importance of missing data in this field of research. Methods Our cross-sectional descriptive report evaluated 10 journals affiliated with pharmacy organizations in the United States, Canada, the United Kingdom, and Australia. Randomized controlled trials, cohort studies, case-control studies, and cross-sectional studies published in 2018 were included. The primary outcome measure was the proportion of studies that reported the handling of missing data in their methods or results. Results A total of 178 studies were included in the analysis. Of these, 19.7% (n = 35) mentioned missing data either in their methods (3.4%, n = 6), results (15.2%, n = 27), or in both sections (1.1%, n = 2). Only 4.5% (n = 8) of the studies mentioned how they handled missing data, the most common method being multiple imputation (n = 3), followed by indicator (n = 2), complete case analysis (n = 2), and simple imputation (n = 1). One study using multiple imputation and both studies using an indicator method also combined other strategies to account for missing data. One study only used complete case analysis for subgroup analysis, and the other study only used this method if a specific baseline variable was missing. Conclusions Very few studies in clinical pharmacy literature report any handling of missing data. This has the potential to lead to biased results. We advocate that researchers should report how missing data were handled to increase the transparency of findings and minimize bias.

Abstract There are several ways of preserving water covering technical, legal and cultural aspects. More recently, Rainwater Harvesting (RWH) has become one of the popular means of water-saving. A few studies on RWH system at place of worship have been undertaken; however, there has not been any detailed study in Australia. This research aims to explore how Islamic scripture can be used to promote water conservation among the Muslim community, specifically, this examines the feasibility of a RWH system at St Marys Islamic Centre, New South Wales, Australia where a RWH system is proposed to supplement mains water for regular uses such as washing, gardening, and socio-religious functions. Based on local daily rainfall data, a water balance model has been developed to estimate reliability of a RWH system at the proposed location. The preliminary result shows that for a 10 kL tank size, the average reliability of the proposed RWH system is 69% for 400 people. However, if the tank size increases, reliability also increases and therefore, higher tank size is needed at the proposed site. Finally, this result will be useful to understand the effects of Islamic motivation and RWH on water preservation. It is also expected that the outcomes of this research will promote water conservation in places of worship and community centres across Australia and other countries.

Full textAbstract:
This paper explores the social reproduction of precarity among white South African migrants in Australia. Building on Griffiths and Prozesky’s elucidation of the white South African imaginary and its role in triggering emigration, we draw on ethnographic data on white South Africans living in Melbourne to argue that our informants reproduce what Hage terms a ‘white nation fantasy’. In documenting the ways our informants’ migration experiences can be read as a function of a threatened social imaginary, we suggest that their ‘successful’ resettlement in Australia points to the congruence of their ontological grounding with the white nation fantasy predominating in Australia. Ultimately, however, we argue that the sense of precarity our informants experience in Australia is intrinsically embedded in their reproduction of the white nation fantasy. Our case study therefore serves as a cautionary tale to inflexible constructions of whiteness globally.

Full textAbstract:
An airborne survey was undertaken on the Mount Isa inlier in 1990–1992. During this survey, both airborne magnetic and gamma‐ray spectrometric data were recorded over 639 170 line-km. Because of perceived value of the radiometric data, stringent calibration procedures, including the creation of a test range, were adopted. In addition to the data from the newly‐flown areas, 76 760 line‐km of existing data were acquired from other companies, and were reprocessed and merged with the Mount Isa survey. The total area covered by the Mount Isa airborne survey was 151 300 km2. Over the last five years, several studies have been undertaken that seek to exploit the Mount Isa region gamma‐ray database and maximise the use of radiometrics for mineral exploration. This paper highlights the results of these studies by focussing on radiometric signatures of major mines in the Mount Isa Inlier, radioelement contour maps, geomagnetic/radiometric interpretation maps, lithological mapping, regolith mapping, geochemical sampling, and spatial modeling using geographical information systems (GIS). Due to the recent introduction of GIS technology and better techniques for handling high quality digital data, there has been a revived interest in making more use of image data sets. The integration of raster and vector data sets for both spectral and spatial modeling has maximized the potential of this approach.

This paper uses part of the data from a larger qualitative inquiry in two International Baccalaureate schools, one in Australia and one in an Indian Ocean Island Nation (a pseudonym), to identify the factors and forces that contribute to the sense of self and understanding of and engagement with the notion of international mindedness in two ‘third culture kids’. Socio-cultural theory is used as a conceptual framework to explore cross-cultural differences and similarities between the students and the schooling contexts. Analysing the students’ perspectives about their understandings of international mindedness through grounded theory methods, the paper also develops hypotheses on the notions of being, belonging and becoming.

Full textAbstract:
AbstractThis paper provides an overview of results from an Australian Research Council-funded project "Sentiments and Risks: The Changing Nature of Human-Animal Relations in Australia." The data discussed come from a survey of 2000 representative Australians at the capital city, state, and rural regional level. It provides both a snapshot of the state of involvement of Australians with nonhuman animals and their views on critical issues: ethics, rights, animals as food, risk from animals, native versus introduced animals, hunting, fishing, and companionate relations with animals. Its data point to key trends and change. The changing position of animals in Australian society is critical to understand, given its historic export markets in meat and livestock, emerging tourism industry with its strong wildlife focus, native animals' place in discourses of nation, and the centrality of animal foods in the national diet. New anxieties about risk from animal-sourced foods and the endangerment of native animals from development and introduced species, together with tensions between animals' rights and the privileging of native species, contribute to the growth of a strongly contested animal politics in Australia.

Full textAbstract:
There has been a rapid uptake on the idea of using multiple sources in marine seismic data acquisition because of the additional flexibility the technique offers in survey design based not only on geophysical quality, but also for health, safety and environment (HSE) and efficiency. This paper examines three case studies conducted in Australia and Indonesia covering aspects of the advantages. An important consideration in survey design is efficiency, and multisource designs improve this by allowing wider spreads to be towed, so more data is acquired per vessel pass. In turn, HSE exposure is decreased by reducing survey times and by reducing the amount of in-sea equipment. The Trepang Survey carried out for Ophir Energy offshore West Papua was designed for efficiency, but the HSE aspect came to the fore when large amounts of floating debris (several hundred tree trunks) were found in the path of the survey vessel. By reducing the acquisition time, the risk the timber posed was minimised. The Cygnus survey in the Vulcan sub-basin is an example of where the multisource technique increased quality by improving the cross-line resolution and increasing fold without decreasing efficiency. Bianchi and Hockey were two surveys in the same area and, because the surveys were small, they were inefficient to acquire because much of the time was spent on line changes. The operator Quadrant used the fact that a triple-source design would allow for symmetrical bins to be acquired and joined the two small surveys together: effectively two sets of line change times were turned into acquisition time.

Full textAbstract:
Community monitoring began in Australia in the 1980s primarily as an awareness-raising tool. Since that time, the community has developed increased skills and knowledge in monitoring procedures and both the data collectors and data users are placing greater demands on community data to be accurate and reliable. With over 3,500 community groups in the field collecting data at over 5,000 sites across Australia, the Waterwatch Program has developed guidelines and tools for monitoring and data collection for the community to collect reliable, accurate and useful data. This paper will discuss how Waterwatch is providing technical support through a range of data confidence guidelines and procedures to ensure that community monitoring and community data continue to play a significant role in the protection and management of our waterways. This paper will also draw on a couple of case studies from across Australia that demonstrate community data being used by a variety of stakeholders.

Full textAbstract:
In recent years, a number of case studies have reported a growth in the extent of direct employee involvement in specific workplaces in Australia. On the basis of secondary analysis of the Australian Workplace Industrial Relations Survey data, the author demonstrates that this is in fact a more general phenomenon, even at workplaces where unions have traditionally been well organized. At the same time, the overall pattern of growth has been tempered by a smaller but not insignificant number of deaths as schemes have been discontinued. Suggestion schemes and quality circles have been the techniques most likely to show a high rate of attrition as well as growth, thus demonstrating a high degree of instability. It is suggested that the changing nature of employee involvement, as well as its fluidity, has potential implications for managements and trade unions.

In Australia and across the globe music participation by older people active in the community has the potential to enhance quality of life. A recent review of the literature found clear evidence of numerous benefits from participation in active music making that encompass the social, physical and psychological. This article reports on five phenomenological case studies of community singing groups comprised of older people active in the community in Melbourne, Victoria. These studies are part of a research project, Well-being and Ageing: Community, Diversity and the Arts in Victoria that began in 2008. Interview data were analysed using interpretative phenomenological analysis and are reported under three overarching themes: Social connection, A sense of well-being, and Musical engagement. For older people in these studies singing in community choirs offered opportunities for social cohesion, positive ageing, and music learning that provided a sense of personal and group fulfilment, community engagement and resilience.

Purpose – The purpose of this paper is to identify and analyse the difficulties encountered in the implementation of a voice picking system at a large multinational company of the tractor industrial segment, outlining a comparison related to the main critical factors concerning the system implementation at a Brazilian and a USA plant. Design/methodology/approach – The methodology utilised was qualitative and exploratory conducted through case studies in the two plants of the multinational company. The main data were collected through interviews with key managers directly involved in the project of voice picking system implementation. Findings – The results indicate that the picking processes in the two plants were similar, since both were designed for the production line and conducted using bar-code readers and paper lists. Nevertheless, the internal warehousing process in the USA was more mature and computerised, whereas the Brazilian process still had opportunity for improvement, such as, the visual storage process, where the operator was responsible for locating an empty position. Research limitations/implications – Since this research is an exploratory case study, its results cannot be generalised. Practical implications – The paper provides relevant practical information and experiences to managers interested in implementing voice picking systems, as well as interested in improving the accuracy and productivity of logistics processes within warehouses. Originality/value – The voice picking systems are more widespread in the USA than in Brazil, and therefore, companies around the world can use this studied case to better understand about the voice picking systems implementation process in both emerging and mature marketplaces.

Full textAbstract:
An examination of Environmental Impact Statements (EIS) points to a clear need for change in the current process of Environmental Impact Assessment (EIA) in Australia. The recent approval of a Boatharbour/Marina at Shellharbour, New South Wales, Australia, serves as an example that underscores some of the problems common to most EISs. Budgetary constraints imposed on the ecological consultants can lead to the use of inappropriate methodology and the collection of inaccurate biological data. The limitations in methodology must be taken into consideration in EISs and all conclusions should be substantiated with data or reference to the literature. There is a need for stricter guidelines for ecological studies and monitoring programmes. A comprehensive list of potential impacts requiring consideration in an EIS should be provided for all designated developments. Novel mitigation methods should always be subject to monitoring. The consequences of not proceeding with the development should be considered in conjunction with alternatives to the proposed development and it should be essential to consider ecotourism as an alternative to all purely tourist oriented proposals. There is a need for peer review in the EIA process. Many of the flaws in the Shell Cove EIS might have been negated by more input from independent scientists. The future of ecologically sustainable development in Australia depends on our ability to learn from, and improve on, mistakes from the past.

Full textAbstract:
SUMMARYNational studies determining the burden of gastroenteritis have defined gastroenteritis by its clinical picture, using symptoms to classify cases and non-cases. The use of different case definitions has complicated inter-country comparisons. We selected four case definitions from the literature, applied these to population data from Australia, Canada, Ireland, Malta and the United States, and evaluated how the epidemiology of illness varied. Based on the results, we developed a standard case definition. The choice of case definition impacted on the observed incidence of gastroenteritis, with a 1·5–2·1 times difference between definitions in a given country. The proportion of cases with bloody diarrhoea, fever, and the proportion who sought medical care and submitted a stool sample also varied. The mean age of cases varied by <5 years under the four definitions. To ensure comparability of results between studies, we recommend a standard symptom-based case definition, and minimum set of results to be reported.

The participants in this study are all Australian educators (n=60), undertaking full-time and part-time academic posts, involving learning and teaching activities at universities and other higher educational institutions/providers in Sydney, Australia. As part of the case studies, the individual, personal, and professional teaching and learning journeys of the educators are sketched in details in relation to John Dewey’s four (4) key democratic educational reformative principles. Finally, this research study concludes by providing a realistic response to the following question: Given the current liberal and relatively democratic educational system in New South Wales, are the Australian educators truly given the opportunity to create a positive and constructive future vision for Australia, in general, and the Australian graduates, in particular. The current study further provides a realistic and clear-cut description of the hurdles facing the current educational system in New South Wales, Australia.

Full textAbstract:
Paleoecological techniques are useful tools to identify restoration targets and natural variability for natural resource management programs. However, despite recent advances, caution is required when employing paleoecological techniques in estuaries, due to their dynamic nature relative to lake environments where these techniques were pioneered. This study used a novel combination of chronological, diatom, geochemical and isotopic data to assess the effectiveness of using these techniques in estuaries, and to develop an understanding of environmental changes within Moreton Bay, an open estuarine environment in subtropical east Australia. Results indicated mixed success, with 210Pb results indicating only background unsupported 210Pb levels, 14C results indicating sediment deposition from mixed sources, no diatom preservation and inconsistencies between geochemical and isotope proxies. Evidence did exist that the Moreton Bay sediments have been derived from different sources over the past 10 000 years. However, isotope records were not able to identify the likely sources of these sediments. Problems with diatom preservation were most probably due to the high salinity and temperatures associated with subtropical open embayment estuaries. Future studies attempting to identify environmental histories of estuaries should incorporate river-influenced locations rather than marine-dominated sites to ensure better diatom preservation and more definitive geochemical signals.

Full textAbstract:
The large number of wells associated with typical coal seam gas (CSG) developments in Australia has changed the paradigm for field management and optimisation. Real time data access, automation and optimisation—which have been previously considered luxuries in conventional resources—are key to the development and operation of fields, which can easily reach more than 1,000 wells. The particular issue in Australia of the shortage of skilled labour and operators has increased pressure to automate field operations. This extended abstract outlines established best practices for gathering the numerous data types associated with wells and surface equipment, and converting that data into information that can inform the decision processes of engineers and managers alike. There will be analysis made of the existing standard, tools, software and data management systems from the conventional oil and gas industry, as well as how some of these can be ported to the CSG fields. The need to define industry standards that are similar to those developed over many years in the conventional oil and gas industry will be discussed. Case studies from Australia and wider international CSG operations will highlight the innovative solutions that can be realised through an integrated project from downhole to office, and how commercial off the shelf solutions have advantages over customised one-off systems. Furthermore, case studies will be presented from both CSG and conventional fields on how these enabling technologies translate into increased production, efficiencies and lift optimisation and move towards the goal of allowing engineers to make informed decisions as quickly as possible. Unique aspects of CSG operations, which require similarly unique and innovative solutions, will be highlighted in contrast to conventional oil and gas.

In recent years, influenced by the pervasive power of technology, standards and mandates, Australian hospitals have begun exploring digital forms of keeping this record. The main rationale is the ease of accessing different data sources at the same time by varied staff members. The initial step in this transition was implementation of scanned medical record systems, which converts the paper based records to digitised form, which required process flow redesign and changes to existing modes of work. For maximising the benefits of scanning implementation and to better prepare for the changes, Austin Hospital in the State of Victoria commissioned this research focused on elective admissions area. This structured case study redesigned existing processes that constituted the flow of external patient forms and recommended a set of best practices at the same time highlighting the significance of user participation in maximising the potential benefits anticipated. In the absence of published academic studies focused on Victorian hospitals, this study has become a conduit for other departments in the hospital as well as other hospitals in the incursion.

ABSTRACT Background: Twitter is increasingly used as a medium to communicate scholarly content and facilitate expedited knowledge translation. Academic conferences typically use event-specific hashtags to promote conferences and move conference-related conversations to the public domain. Like other health disciplines, exercise physiology and exercise science attract global interest, and Twitter used during conferences can promote conference content to a broader audience than attendees. However, despite conferences in these disciplines having previously used hashtags, no published studies have examined their use. This study examined the use of the #RTP18 during the 2018 Exercise & Sports Science Australia Research to Practice Conference. Methods: Freely accessible Twitter data were mined using twdocs. Descriptive statistics were used to report the number of original tweets and retweets. Content analysis was used to differentiate original tweets related to specific conference sessions from tweets related to the conference in general. Data are presented for each day of the conference and overall for the three days of the conference. Results: A total of 262 original tweets were identified using the hashtag #RTP18. Seventy-one percent (n = 187) of the original tweets were related to specific conference content, while n = 75 (29%) of original tweets were related to the conference in general. More than 11,500 retweets were identified across the duration of the conference. The mean retweet rate was 12.7 times and ranged from 0–73. Conclusion: Twitter appears to be a powerful tool to extend the reach of conference activities. The use of social media may enhance organizational and personal networking opportunities for conference delegates.

AbstractBoth transnationality and its evolving nature have been the persistent themes of many studies. However, they have often been considered separately, producing insufficient evidence to explain why migrants and their communities have acted in transnational ways and how transnationality repeatedly acts on diasporic identity. This article will use the data collected in the Chinese community in Australia to explore the correlation between the transnationality of individual migrants and the evolving nature of their diasporic identities. The discussion will outline and analyze various transnational activities that have taken place in the community since the early 1990s, focusing on their form, content and trajectory, as well as their organizational structures and meaning. The article will conclude with an explanation about why community members initiate the transnational activities, what goals they have set for their transnational lives and how transnationality and their identity are correlated.

Full textAbstract:
SUMMARYLaboratory-based surveillance by OzFoodNet in Australia and FoodNet in the USA indicated that the incidence of Campylobacter infections in 2001 in Australia was about nine times higher than in the USA. We assessed whether this disparity could be explained by differences in the frequency of stool culturing. Using data from population surveys of diarrhoea and symptom profiles for Campylobacter from case-control studies, indices of healthcare behaviour taking into account the severity of Campylobacter infections were calculated. These suggest that culture-confirmed Campylobacter infections underestimate the incidence of community cases by similar ratios in the two countries. The incidence of Campylobacter infections in Australia was about 12 times higher than in the USA after consideration of healthcare system differences.

<p>Cost and time overruns are the key problems of any construction projects. These issues are causing the negative impact on the development of country economic growth and prosperity. To overcome these issues, the paper is aimed to discover the most influence factors causing the project delay and cost overruns and recommend the possible measures by investigating case studies in three different countries in the world. Each country’s quantitative data from the past studies was selected to analyze and recommend the effective measures. A questionnaire survey was conducted in all three case studies adopting different data collection strategy. The reason of selecting three case studies is to outline the compare analysis of delay factors and to classify why different delay factors have different priority level of influence in project delay from one country to another country. The findings from the case studies exposed that the most influential factors in Australia are (1) planning and scheduling deficiencies, (2) methods of construction, (3) effective monitoring and feedback process, whereas in Ghana, (1) delay in payment certificates (2) underestimating of project cost, (3) complexity of projects are the most influential factors. However, in Malaysia (1) Contractor’s improper planning, (2) poor site management, (3) inadequate contractor experience are the most influential factors. This paper has also analysed the average and least impact of the delay factors causing project delay and cost overruns in those countries. The paper concludes that there are diverse groups of delay factors from one country to another country that causing project delay and cost overruns. It also concludes that there are diverse measures according to the nature of delay factors to reduce the impact on project delay and cost overruns in construction industry.</p><p><strong>Journal of Advanced College of Engineering and Management</strong>, Vol. 2, 2016, Page: 41-55</p>

Full textAbstract:
This paper demonstrates the contribution that historical property records can make to our understanding of long run urban change. We use a case study of two streets from the suburb of Carlton in Melbourne, Australia between 1870 and 1970. The property records form a panel database that can be interrogated using standard modelling techniques. These data are used to analyse change in the built environment over time, and identify the factors that may be influencing such change. With the assembled data we track built form, land value, ownership and land use over 100 years. We find that stability characterises the built environment over lengthy periods, but when change occurs it does so in bursts, rather than incrementally. Furthermore, these bursts of change are unevenly spread across our two case study streets, despite their proximity. The streetscape’s primary built material is the key factor shaping geographical patterns of land use change in the case study area.

Abstract The identification of extratropical fronts in reanalyses and climate models is an important climate diagnostic that aids dynamical understanding and model verification. This study compares six frontal identification methods that are applied to June and July reanalysis data over the Central Wheatbelt of southwest Western Australia for 1979–2006. Much of the winter rainfall over this region originates from frontal systems. Five of the methods use automated algorithms. These make use of different approaches, based on shifts in 850-hPa winds (WND), gradients of temperature (TGR) and wet-bulb potential temperature (WPT), pattern matching (PMM), and a self-organizing map (SOM). The sixth method was a manual synoptic technique (MAN). On average, about 50% of rain days were associated with fronts in most schemes (although methods PMM and SOM exhibited a lower percentage). On a daily basis, most methods identify the same systems more than 50% of the time, and over the 28-yr period the seasonal time series correlate strongly. The association with rainfall is less clear. The WND time series of seasonal frontal counts correlate significantly with Central Wheatbelt rainfall. All automated methods identify fronts on some days that are classified as cutoff lows in the manual analysis, which will impact rainfall correlations. The front numbers identified on all days by the automated methods decline from 1979 to 2006 (but only the TGR and WPT trends were significant at the 10% level). The results here highlight that automated techniques have value in understanding frontal behavior and can be used to identify the changes in the frequency of frontal systems through time.

"A Streamflow Bias Correction and Performance Evaluation Web Application for GEOGloWS ECMWF Streamflow Services." Hydrology 8, no. 2 (April 25, 2021): 71. http://dx.doi.org/10.3390/hydrology8020071.
Full textAbstract:
We present the development and testing of a web application called the historical validation tool (HVT) that processes and visualizes observed and simulated historical stream discharge data from the global GEOGloWS ECMWF streamflow services (GESS), performs seasonally adjusted bias correction, computes goodness-of-fit metrics, and performs forward bias correction on subsequent forecasts. The HVT corrects GESS output at a local scale using a technique that identifies and corrects model bias using observed hydrological data that are accessed using web services. HVT evaluates the performance of the GESS historic simulation data and provides more accurate historic simulation and bias-corrected forecast data. The HVT also allows users of the GEOGloWS historical streamflow data to use local observed data to both validate and improve the accuracy of local streamflow predictions. We developed the HVT using Tethys Platform, an open-source web application development framework. HVT presents data visualization using web mapping services and data plotting in the web map interface while functions related to bias correction, metrics reporting, and data generation for statistical analysis are computed by the back end. We present five case studies using the HVT in Australia, Brazil, Colombia, the Dominican Republic, and Peru. In these case studies, in addition to presenting the application, we evaluate the accuracy of the method we implemented in the HVT for bias correction. These case studies show that the HVT bias correction in Brazil, Colombia, and Peru results in significant improvement in historic simulation across the countries, while bias correction only resulted in marginal historic simulation improvements in Australia and the Dominican Republic. The HVT web application allows users to use local data to adjust global historical simulation and forecasts and validate the results, making the GESS modeling results more useful at a local scale.

Full textAbstract:
A problem common to mines operating in the tropics is the disposal of water, which may be alkaline, acidic, or contain toxic elements such as arsenic or cadmium. The availability of year-round water supply at many mine sites in Northern Australia, particularly from pit dewatering, together with the monsoonal climate, provide appropriate conditions for the formation of natural wetlands or establishment of artificial wetlands. Wetland species (particularly Typha spp.) flourish in the presence of flowing or shallow water from dewatering, and data collected from natural and experimental wetlands show reduction of metal concentrations by wetland filtration of mine waste water. The following case studies are considered:Constructed wetlands, used to remove uranium from waste rock runoff before release to an adjacent creek provide a means of “polishing” runoff water prior to discharge to the creek.Creek-Billabong systems with existing wetlands adjacent to mine sites adventitiously “filter” waters discharged from mine sites. Trace elements in dewatering water from a gold mine discharged into an oxbow show reduction of elemental concentrations downstream, compared to discharge water.Naturally generated wetlands at several Northern Territory mines have developed along channels for discharge of pit water, with ingress of Typha domingensis. Such wetlands, associated with dewatering, have been examined at four mines, some with acid mine drainage. Water quality measured after wetland treatments shows reductions in concentrations of various heavy metals and sulfate. Volunteer Typha domingensis grows and spreads in shallow flowing channels, providing an inherent “filtration” of the water.Natural swamplands are incorporated in the waste rock runoff management design of a new gold mine, to reduce potentially high arsenic levels in the waste water. Constructed and naturally occurring wetlands may be used in the treatment of most mine waste waters to achieve levels of constituents acceptable for discharge to the surrounding environment.

Full textAbstract:
Traffic incidents such as crashes, vehicle breakdowns, and hazards impact traffic speeds and induce congestion. Recognizing the factors that influence the frequency of these traffic incidents is helpful in proposing countermeasures. There have been several studies on evaluating crash frequencies. However, research on other incident types is sparse. The main objective of this research is to identify critical variables that affect the number of reported vehicle breakdowns. A traffic incident dataset covering 4.5 years (January 2012 to June 2016) in the Australian state of New South Wales (NSW) was arranged in a panel data format, consisting of monthly reported vehicle breakdowns in 28 SA4s (Statistical Area Level 4) in NSW. The impact of different independent variables on the number of breakdowns reported in each month–SA4 observation is captured using a random-effect negative binomial regression model. The results indicate that increases in population density, the number of registered vehicles, the number of public holidays, average temperature, the percentage of heavy vehicles, and percentage of white-collared jobs in an area increase the number of breakdowns. On the other hand, an increase in the percentage of unrestricted driving licenses and families with children, number of school holidays, and average rainfall decrease the breakdown frequency. The insights offered in this study contribute to a complete picture of the relevant factors that can be used by transport authorities, vehicle manufacturers, sellers, roadside assistance companies, and mechanics to better manage the impact of vehicle breakdowns.

Full textAbstract:
This paper discusses the potential relationship between surveillance techniques, the enactment of security measures, and patient violence in mental health wards. The paper draws upon data from an ethnographic study conducted in a purpose-built mental health unit containing two wards (one locked and one open) in South Australia, and argues that acts of violence observed in the unit were typically preceded by an incident within the unit that was related to the implementation of security measures aimed at controlling non-compliant behaviours. The paper argues that if a relationship between security measures and violence does exist in mental health wards, then close attention must be paid to the ways in which forms of surveillance may arguably exacerbate, rather than prevent, the need for security measures.

Full textAbstract:
Purpose: Previously there are many studies that focused on risk management in general context and little attention was paid on how supply chain risks management effects an organization profit and performance. The main aim of our study to explore the effect of supply chain risk management on organization performance in national foods Manooabad Muridke district Sheikhupura.
Methodology: This study conducted in National foods Manooabad Muridke. Data were collected by using questioner from the employees of National foods Manooabad Muridke. SPSS 22 (Statistical package for social sciences) was used to analyze the collected data.
Main Findings: This study is an attempt to check the effects of supply chain risk management variables to the performance of the organization. Three main supply chain risk management variables were identified namely, supply chain risk identification, supply chain risk sources and supply chain risk mitigation. We find that risk register method is mainly used for the identification of risks in the supply chain at any level. The most important risks of our study that are supplier risks, environmental risks, political risks, markets risks, warehousing risks, and financial risks. In mitigation strategies that are good to mitigate the risk in supply chain risk avoidance measures, risk control measures and risk cooperation measures.
Applications: We concluded that it is important for an organization to identify risks proactively as early as possible in the decision-making process. Different types of risks need to be identified in all process of supply chains. After all the identification of risks, the organization needs to be mitigated these risks by using different mitigate strategies plan.
Originality: In the future, this study will be helpful for many organizations which deal with food items consumed by people. As in this study, we worked on supply chain risks and their management before many studies were conducted generally on risk management so this study especially focused on supply chain risks. There is a need to conduct more study in this regard in different industries so better information available to people to control risks in supply chain management.
