Academic literature on the topic 'Organic wastes Victoria Melbourne'

River Nzoia is the largest river draining into the Kenyan portion of Lake Victoria. This river receives both point sources of pollution from industrial and municipal wastes, and non-point sources from agricultural runoff in the catchment. The objective of this study was to simulate dissolved oxygen (DO) and biochemical oxygen demand (BOD) of the middle section of River Nzoia using MIKE 11 model. The model was calibrated using discharge and water quality data for 2009 and validated with March–April 2013 data. The model performance was good with coefficient of determination (R2) values of between 0.845 and 0.995, Nash–Sutcliffe efficiency values of between 0.748 and 0.993 and percent bias of less than 10 for both calibration and validation of electrical conductivity (EC), DO and BOD. EC and BOD values were lower for April compared to March which could be attributed to dilution during high flows. DO values were above the recommended minimum level of 4 mg/l in all the sections of the river in the wet period but some sections had lower than 4 mg/l during low flow period. The government agencies such as Water Resources Management Authority and National Environment Management Authority should enforce the effluent standards to ensure that industries and wastewater treatment plants adhere to the maximum allowable limit for BOD and also improve their treatment efficiencies of wastewater plants so as to improve the quality of River Nzoia which is important in the overall management of the Lake Victoria basin.

Relatively untreated (screened) municipal wastes from the City of Victoria, B.C. and environs are discharged to the sea as effluent from two long outfall pipes, only one of which (Macaulay Point) discharges to a depositional zone. Sediments along transects away from the Macaulay Point outfall were collected and the following parameters determined: contamination (selected chemicals of concern), toxicity (polychaete survival and growth, amphipod survival, and bivalve larvae abnormalities), and benthic infaunal community structure. Significant sediment contamination was restricted to within 100-400 m of the outfall with the exception of high PAH contamination due to the shipwreck of a collier in 1891. Sediment toxicity was restricted to effects on growth and development, also within 100-400 m of the outfall; survival was near control levels even at the outfall terminus. Benthic infaunal community structure indicated “moderate pollution” within 100 m of the outfall and showed a classic organic enrichment pattern of increasing species richness and lower abundance with distance from the outfall. Overall, the impact of the outfall on the sediments is minimal, highly restricted in extent, and not of major environmental concern. A public referendum, conducted after the release of this and of other scientific studies, resulted in the deferral of primary effluent treatment.

Purpose The purpose of this study was to examine the concept of value in healthcare through a practical appraisal of the applicability of a conceptual framework, which is aimed at supporting the measurement and realisation of financial benefits from process improvement (PI) activities in a hospital setting. Design/methodology/approach A single case study of a hospital system in Melbourne, Victoria, Australia, was used to assess the applicability of the framework. The study sought to verify the framework's intention, that PI methods could be used to address known wastes that contribute to the cost of providing healthcare. The case study examines the current approach taken by the hospital to measure and realise financial benefits from PI activities and compares these to the components of the Strategy to Balance Cost and Quality in Health Care framework to assess its applicability in practice. Findings The case study revealed that the steps described in the framework were fundamentally in place albeit with some variation. Importantly, the case study identified an additional step that could be added into the framework to support hospitals to better define their portfolio of initiatives to deliver value. The case study also clarified three types of contributory elements that should be in place for the application of the framework to be successful. Practical implications The Framework to Achieve Value in Healthcare is offered to hospitals as a model by which they can look to reduce expenditure through the removal of non-value adding activities. The modification to the conceptual framework has arisen from a single case study and would benefit from further testing by other hospitals in other policy settings (i.e. other countries). Originality/value This is the first paper to examine and enhance an existing framework to assist hospitals balance cost and quality through PI.

This article investigates the possibilities for understanding waste as a resource, with a particular focus on understanding food waste as a food resource. It considers the popular yeast spread Vegemite within this frame. The spread’s origins in waste product, and how it has achieved and sustained its status as a popular symbol of Australia despite half a century of Australian gastro-multiculturalism and a marked public resistance to other recycling and reuse of food products, have not yet been a focus of study. The process of producing Vegemite from waste would seem to align with contemporary moves towards recycling food waste, and ensuring environmental sustainability and food security, yet even during times of austerity and environmental concern this has not provided the company with a viable marketing strategy. Instead, advertising copywriting and a recurrent cycle of product memorialisation have created a superbrand through focusing on Vegemite’s nutrient and nostalgic value.John Scanlan notes that producing waste is a core feature of modern life, and what we dispose of as surplus to our requirements—whether this comprises material objects or more abstract products such as knowledge—reveals much about our society. In observing this, Scanlan asks us to consider the quite radical idea that waste is central to everything of significance to us: the “possibility that the surprising core of all we value results from (and creates even more) garbage (both the material and the metaphorical)” (9). Others have noted the ambivalent relationship we have with the waste we produce. C. T. Anderson notes that we are both creator and agent of its disposal. It is our ambivalence towards waste, coupled with its ubiquity, that allows waste materials to be described so variously: negatively as garbage, trash and rubbish, or more positively as by-products, leftovers, offcuts, trimmings, and recycled.This ambivalence is also crucial to understanding the affectionate relationship the Australian public have with Vegemite, a relationship that appears to exist in spite of the product’s unpalatable origins in waste. A study of Vegemite reveals that consumers can be comfortable with waste, even to the point of eating recycled waste, as long as that fact remains hidden and unmentioned. In Vegemite’s case not only has the product’s connection to waste been rendered invisible, it has been largely kept out of sight despite considerable media and other attention focusing on the product. Recycling Food Waste into Food ProductRecent work such as Elizabeth Royte’s Garbage Land and Tristram Stuart’s Waste make waste uncomfortably visible, outlining how much waste, and food waste in particular, the Western world generates and how profligately this is disposed of. Their aim is clear: a call to less extravagant and more sustainable practices. The relatively recent interest in reducing our food waste has, of course, introduced more complexity into a simple linear movement from the creation of a food product, to its acquisition or purchase, and then to its consumption and/or its disposal. Moreover, the recycling, reuse and repurposing of what has previously been discarded as waste is reconfiguring the whole idea of what waste is, as well as what value it has. The initiatives that seem to offer the most promise are those that reconfigure the way waste is understood. However, it is not only the process of transforming waste from an abject nuisance into a valued product that is central here. It is also necessary to reconfigure people’s acculturated perceptions of, and reactions to waste. Food waste is generated during all stages of the food cycle: while the raw materials are being grown; while these are being processed; when the resulting food products are being sold; when they are prepared in the home or other kitchen; and when they are only partly consumed. Until recently, the food industry in the West almost universally produced large volumes of solid and liquid waste that not only posed problems of disposal and pollution for the companies involved, but also represented a reckless squandering of total food resources in terms of both nutrient content and valuable biomass for society at large. While this is currently changing, albeit slowly, the by-products of food processing were, and often are, dumped (Stuart). In best-case scenarios, various gardening, farming and industrial processes gather household and commercial food waste for use as animal feed or as components in fertilisers (Delgado et al; Wang et al). This might, on the surface, appear a responsible application of waste, yet the reality is that such food waste often includes perfectly good fruit and vegetables that are not quite the required size, shape or colour, meat trimmings and products (such as offal) that are completely edible but extraneous to processing need, and other high grade product that does not meet certain specifications—such as the mountains of bread crusts sandwich producers discard (Hickman), or food that is still edible but past its ‘sell by date.’ In the last few years, however, mounting public awareness over the issues of world hunger, resource conservation, and the environmental and economic costs associated with food waste has accelerated efforts to make sustainable use of available food supplies and to more efficiently recycle, recover and utilise such needlessly wasted food product. This has fed into and led to multiple new policies, instances of research into, and resultant methods for waste handling and treatment (Laufenberg et al). Most straightforwardly, this involves the use or sale of offcuts, trimmings and unwanted ingredients that are “often of prime quality and are only rejected from the production line as a result of standardisation requirements or retailer specification” from one process for use in another, in such processed foods as soups, baby food or fast food products (Henningsson et al. 505). At a higher level, such recycling seeks to reclaim any reusable substances of significant food value from what could otherwise be thought of as a non-usable waste product. Enacting this is largely dependent on two elements: an available technology and being able to obtain a price or other value for the resultant product that makes the process worthwhile for the recycler to engage in it (Laufenberg et al). An example of the latter is the use of dehydrated restaurant food waste as a feedstuff for finishing pigs, a reuse process with added value for all involved as this process produces both a nutritious food substance as well as a viable way of disposing of restaurant waste (Myer et al). In Japan, laws regarding food waste recycling, which are separate from those governing other organic waste, are ensuring that at least some of food waste is being converted into animal feed, especially for the pigs who are destined for human tables (Stuart). Other recycling/reuse is more complex and involves more lateral thinking, with the by-products from some food processing able to be utilised, for instance, in the production of dyes, toiletries and cosmetics (Henningsson et al), although many argue for the privileging of food production in the recycling of foodstuffs.Brewing is one such process that has been in the reuse spotlight recently as large companies seek to minimise their waste product so as to be able to market their processes as sustainable. In 2009, for example, the giant Foster’s Group (with over 150 brands of beer, wine, spirits and ciders) proudly claimed that it recycled or reused some 91.23% of 171,000 tonnes of operational waste, with only 8.77% of this going to landfill (Foster’s Group). The treatment and recycling of the massive amounts of water used for brewing, rinsing and cooling purposes (Braeken et al.; Fillaudeaua et al.) is of significant interest, and is leading to research into areas as diverse as the development microbial fuel cells—where added bacteria consume the water-soluble brewing wastes, thereby cleaning the water as well as releasing chemical energy that is then converted into electricity (Lagan)—to using nutrient-rich wastewater as the carbon source for creating bioplastics (Yu et al.).In order for the waste-recycling-reuse loop to be closed in the best way for securing food supplies, any new product salvaged and created from food waste has to be both usable, and used, as food (Stuart)—and preferably as a food source for people to consume. There is, however, considerable consumer resistance to such reuse. Resistance to reusing recycled water in Australia has been documented by the CSIRO, which identified negative consumer perception as one of the two primary impediments to water reuse, the other being the fundamental economics of the process (MacDonald & Dyack). This consumer aversion operates even in times of severe water shortages, and despite proof of the cleanliness and safety of the resulting treated water. There was higher consumer acceptance levels for using stormwater rather than recycled water, despite the treated stormwater being shown to have higher concentrations of contaminants (MacDonald & Dyack). This reveals the extent of public resistance to the potential consumption of recycled waste product when it is labelled as such, even when this consumption appears to benefit that public. Vegemite: From Waste Product to Australian IconIn this context, the savoury yeast spread Vegemite provides an example of how food processing waste can be repurposed into a new food product that can gain a high level of consumer acceptability. It has been able to retain this status despite half a century of Australian gastronomic multiculturalism and the wide embrace of a much broader range of foodstuffs. Indeed, Vegemite is so ubiquitous in Australian foodways that it is recognised as an international superbrand, a standing it has been able to maintain despite most consumers from outside Australasia finding it unpalatable (Rozin & Siegal). However, Vegemite’s long product history is one in which its origin as recycled waste has been omitted, or at the very least, consistently marginalised.Vegemite’s history as a consumer product is narrated in a number of accounts, including one on the Kraft website, where the apocryphal and actual blend. What all these narratives agree on is that in the early 1920s Fred Walker—of Fred Walker and Company, Melbourne, canners of meat for export and Australian manufacturers of Bonox branded beef stock beverage—asked his company chemist to emulate Marmite yeast extract (Farrer). The imitation product was based, as was Marmite, on the residue from spent brewer’s yeast. This waste was initially sourced from Melbourne-based Carlton & United Breweries, and flavoured with vegetables, spices and salt (Creswell & Trenoweth). Today, the yeast left after Foster Group’s Australian commercial beer making processes is collected, put through a sieve to remove hop resins, washed to remove any bitterness, then mixed with warm water. The yeast dies from the lack of nutrients in this environment, and enzymes then break down the yeast proteins with the effect that vitamins and minerals are released into the resulting solution. Using centrifugal force, the yeast cell walls are removed, leaving behind a nutrient-rich brown liquid, which is then concentrated into a dark, thick paste using a vacuum process. This is seasoned with significant amounts of salt—although less today than before—and flavoured with vegetable extracts (Richardson).Given its popularity—Vegemite was found in 2009 to be the third most popular brand in Australia (Brand Asset Consulting)—it is unsurprising to find that the product has a significant history as an object of study in popular culture (Fiske et al; White), as a marker of national identity (Ivory; Renne; Rozin & Siegal; Richardson; Harper & White) and as an iconic Australian food, brand and product (Cozzolino; Luck; Khamis; Symons). Jars, packaging and product advertising are collected by Australian institutions such as Sydney’s Powerhouse Museum and the National Museum of Australia in Canberra, and are regularly included in permanent and travelling exhibitions profiling Australian brands and investigating how a sense of national identity is expressed through identification with these brands. All of this significant study largely focuses on how, when and by whom the product has been taken up, and how it has been consumed, rather than its links to waste, and what this circumstance could add to current thinking about recycling of food waste into other food products.It is worth noting that Vegemite was not an initial success in the Australian marketplace, but this does not seem due to an adverse public perception to waste. Indeed, when it was first produced it was in imitation of an already popular product well-known to be made from brewery by-products, hence this origin was not an issue. It was also introduced during a time when consumer relationships to waste were quite unlike today, and thrifty re-use of was a common feature of household behaviour. Despite a national competition mounted to name the product (Richardson), Marmite continued to attract more purchasers after Vegemite’s launch in 1923, so much so that in 1928, in an attempt to differentiate itself from Marmite, Vegemite was renamed “Parwill—the all Australian product” (punning on the idea that “Ma-might” but “Pa-will”) (White 16). When this campaign was unsuccessful, the original, consumer-suggested name was reinstated, but sales still lagged behind its UK-owned prototype. It was only after remaining in production for more than a decade, and after two successful marketing campaigns in the second half of the 1930s that the Vegemite brand gained some market traction. The first of these was in 1935 and 1936, when a free jar of Vegemite was offered with every sale of an item from the relatively extensive Kraft-Walker product list (after Walker’s company merged with Kraft) (White). The second was an attention-grabbing contest held in 1937, which invited consumers to compose Vegemite-inspired limericks. However, it was not the nature of the product itself or even the task set by the competition which captured mass attention, but the prize of a desirable, exotic and valuable imported Pontiac car (Richardson 61; Superbrands).Since that time, multinational media company, J Walter Thompson (now rebranded as JWT) has continued to manage Vegemite’s marketing. JWT’s marketing has never looked to Vegemite’s status as a thrifty recycler of waste as a viable marketing strategy, even in periods of austerity (such as the Depression years and the Second World War) or in more recent times of environmental concern. Instead, advertising copywriting and a recurrent cycle of cultural/media memorialisation have created a superbrand by focusing on two factors: its nutrient value and, as the brand became more established, its status as national icon. Throughout the regular noting and celebration of anniversaries of its initial invention and launch, with various commemorative events and products marking each of these product ‘birthdays,’ Vegemite’s status as recycled waste product has never been more than mentioned. Even when its 60th anniversary was marked in 1983 with the laying of a permanent plaque in Kerferd Road, South Melbourne, opposite Walker’s original factory, there was only the most passing reference to how, and from what, the product manufactured at the site was made. This remained the case when the site itself was prioritised for heritage listing almost twenty years later in 2001 (City of Port Phillip).Shying away from the reality of this successful example of recycling food waste into food was still the case in 1990, when Kraft Foods held a nationwide public campaign to recover past styles of Vegemite containers and packaging, and then donated their collection to Powerhouse Museum. The Powerhouse then held an exhibition of the receptacles and the historical promotional material in 1991, tracing the development of the product’s presentation (Powerhouse Museum), an occasion that dovetailed with other nostalgic commemorative activities around the product’s 70th birthday. Although the production process was noted in the exhibition, it is noteworthy that the possibilities for recycling a number of the styles of jars, as either containers with reusable lids or as drinking glasses, were given considerably more notice than the product’s origins as a recycled product. By this time, it seems, Vegemite had become so incorporated into Australian popular memory as a product in its own right, and with such a rich nostalgic history, that its origins were no longer of any significant interest or relevance.This disregard continued in the commemorative volume, The Vegemite Cookbook. With some ninety recipes and recipe ideas, the collection contains an almost unimaginably wide range of ways to use Vegemite as an ingredient. There are recipes on how to make the definitive Vegemite toast soldiers and Vegemite crumpets, as well as adaptations of foreign cuisines including pastas and risottos, stroganoffs, tacos, chilli con carne, frijole dip, marinated beef “souvlaki style,” “Indian-style” chicken wings, curries, Asian stir-fries, Indonesian gado-gado and a number of Chinese inspired dishes. Although the cookbook includes a timeline of product history illustrated with images from the major advertising campaigns that runs across 30 pages of the book, this timeline history emphasises the technological achievement of Vegemite’s creation, as opposed to the matter from which it orginated: “In a Spartan room in Albert Park Melbourne, 20 year-old food technologist Cyril P. Callister employed by Fred Walker, conducted initial experiments with yeast. His workplace was neither kitchen nor laboratory. … It was not long before this rather ordinary room yielded an extra-ordinary substance” (2). The Big Vegemite Party Book, described on its cover as “a great book for the Vegemite fan … with lots of old advertisements from magazines and newspapers,” is even more openly nostalgic, but similarly includes very little regarding Vegemite’s obviously potentially unpalatable genesis in waste.Such commemorations have continued into the new century, each one becoming more self-referential and more obviously a marketing strategy. In 2003, Vegemite celebrated its 80th birthday with the launch of the “Spread the Smile” campaign, seeking to record the childhood reminisces of adults who loved Vegemite. After this, the commemorative anniversaries broke free from even the date of its original invention and launch, and began to celebrate other major dates in the product’s life. In this way, Kraft made major news headlines when it announced that it was trying to locate the children who featured in the 1954 “Happy little Vegemites” campaign as part of the company’s celebrations of the 50th anniversary of the television advertisement. In October 2006, these once child actors joined a number of past and current Kraft employees to celebrate the supposed production of the one-billionth jar of Vegemite (Rood, "Vegemite Spreads" & "Vegemite Toasts") but, once again, little about the actual production process was discussed. In 2007, the then iconic marching band image was resituated into a contemporary setting—presumably to mobilise both the original messages (nutritious wholesomeness in an Australian domestic context) as well as its heritage appeal. Despite the real interest at this time in recycling and waste reduction, the silence over Vegemite’s status as recycled, repurposed food waste product continued.Concluding Remarks: Towards Considering Waste as a ResourceIn most parts of the Western world, including Australia, food waste is formally (in policy) and informally (by consumers) classified, disposed of, or otherwise treated alongside garden waste and other organic materials. Disposal by individuals, industry or local governments includes a range of options, from dumping to composting or breaking down in anaerobic digestion systems into materials for fertiliser, with food waste given no special status or priority. Despite current concerns regarding the security of food supplies in the West and decades of recognising that there are sections of all societies where people do not have enough to eat, it seems that recycling food waste into food that people can consume remains one of the last and least palatable solutions to these problems. This brief study of Vegemite has attempted to show how, despite the growing interest in recycling and sustainability, the focus in both the marketing of, and public interest in, this iconic and popular product appears to remain rooted in Vegemite’s nutrient and nostalgic value and its status as a brand, and firmly away from any suggestion of innovative and prudent reuse of waste product. That this is so for an already popular product suggests that any initiatives that wish to move in this direction must first reconfigure not only the way waste itself is seen—as a valuable product to be used, rather than as a troublesome nuisance to be disposed of—but also our own understandings of, and reactions to, waste itself.Acknowledgements Many thanks to the reviewers for their perceptive, useful, and generous comments on this article.

IntroductionIn late 2016, I undertook a short-term, three-month project to share some of my research through my Instagram account using the categorising hashtag #AustralianBeachspace. Much of this work emerged from my PhD thesis, which is being published in journal articles, but has yet to be published in any accessible or overarching way. I wanted to experiment with the process of using a visual social media tool for research dissemination. I felt that Instagram’s ability to combine text and image allowed for an aesthetically interesting way to curate this particular research project. My research is concerned with representations of the Australian beach, and thus the visual, image-based focus of Instagram seemed ideal. In this article, I briefly examine some of the existing research around academic practices of research dissemination, social media use, and the emerging research around Instagram itself. I then will examine my own experience of using Instagram as a tool for depicting curated, aesthetically-driven, research dissemination and reflect whether this use of Instagram is effective for representing and disseminating research. Research DisseminationResearchers, especially those backed by public funding, are always bound by the necessity of sharing the findings and transferring the knowledge gained during the research process. Research metrics are linked to workload allocations and promotion pathways for university researchers, providing clear motivation to maintain an active research presence. For most academics, the traditional research dissemination strategies involve academic publications: peer-reviewed scholarly books and journal articles.For academics working within a higher education policy climate that centres on measuring impact and engagement, peer-reviewed publications remain the gold standard. There are indicators, however, that research dissemination strategies may need to include methods for targeting non-academic outputs. Gunn and Mintrom (21), in their recent research, “anticipate that governments will increasingly question the value of publicly funded research and seek to evaluate research impact”. And this process, they argue, is not without challenges. Education Minister Simon Birmingham supports their claim by suggesting the Turnbull Government is looking to find methods for more meaningful ways of evaluating value in higher education research outcomes, “rather than only allocating funding to researchers who spend their time trying to get published in journals” (para 5).It therefore makes sense that academics are investigating ways of using social media as a way of broadening their research dissemination, despite the fact social media metrics do not yet count towards traditional citations within the university sector.Research Dissemination via Social MediaThere has been an established practice of researchers using social media, especially blogging (Kirkup) and Twitter, as ways of sharing information about their current projects, their findings, their most recent publications, or to connect with colleagues. Gruzd, Staves, and Wilk (2348) investigated social media use by academics, suggesting “scholars are turning to social media tools professionally because they are more convenient for making new connections with peers, collaboration, and research dissemination”. It is possible to see social media functioning as a new way of representing research – playing an important role in the shaping and developing of ideas, sharing those ideas, and functioning as a dissemination tool after the research has concluded.To provide context for the use of social media in research, this section briefly covers blogging and Twitter, two methods considered somewhat separated from university frameworks, and also professional platforms, such as Academia.edu and The Conversation.Perhaps the tool that has the most history in providing another avenue for academics to share their work is academic blogging. Blogging is considered an avenue that allows for discussion of topics prior to publication (Bukvova, 4; Powell, Jacob, and Chapman, 273), and often uses a more conversational tone than academic publishing. It provides opportunity to share research in long form to an open, online audience. Academic blogs have also become significant parts of online academic communities, such as the highly successful blog, The Thesis Whisperer, targeted for research students. However, many researchers in this space note the stigma attached to blogging (and other forms of social media) as useless or trivial; for instance, in Gruzd, Staves, and Wilk’s survey of academic users of social media, an overwhelming majority of respondents suggested that institutions do not recognise these activities (2343). Because blogging is not counted in publication metrics, it is possible to dismiss this type of activity as unnecessary.Twitter has garnered attention within the academic context because of its proliferation in conference engagement and linking citation practices of scholars (Marht, Weller, and Peters, 401–406). Twitter’s platform lends itself as a place to share citations of recently published material and a way of connecting with academic peers in an informal, yet meaningful way. Veletsianos has undertaken an analysis of academic Twitter practices, and there is a rise in popularity of “Tweetable Abstracts” (Else), or the practice of refining academic abstracts into a shareable Tweet format. According to Powell, Jacob, and Chapman (272), new media (including both Twitter and the academic blog) offer opportunities to engage with an increasingly Internet-literate society in a way that is perhaps more meaningful and certainly more accessible than traditional academic journals. Like blogging, the use of Twitter within the active research phase and pre-publication, means the platform can both represent and disseminate new ideas and research findings.Both academic blogs and Twitter are widely accessible and can be read by Internet users beyond academia. It appears likely, however, that many blogs and academic Twitter profiles are still accessed and consumed primarily by academic audiences. This is more obvious in the increasingly popular specific academic social media platforms such as ResearchGate or Academia.edu.These websites are providing more targeted, niche communication and sharing channels for scholars working in higher education globally, and their use appears to be regularly encouraged by institutions. These sites attempt to mediate between open access and copyright in academic publishing, encouraging users to upload full-text documents of their publications as a means of generating more attention and citations (Academia.edu cites Niyazov et al’s study that suggests articles posted to the site had improved citation counts). ResearchGate and Academia.edu function primarily as article repositories, albeit with added social networking opportunities that differentiate them from more traditional university repositories.In comparison, the success of the online platform The Conversation, with its tagline “Academic rigour, journalistic flair”, shows the growing enthusiasm and importance of engaging with more public facing outlets to share forms of academic writing. Many researchers are using The Conversation as a way of sharing their research findings through more accessible, shorter articles designed for the general public; these articles regularly link to the traditional academic publications as well.Research dissemination, and how the uptake of online social networks is changing individual and institution-wide practices, is a continually expanding area of research. It is apparent that while The Conversation has been widely accepted and utilised as a tool of research dissemination, there is still some uncertainty about using social media as representing or disseminating findings and ideas because of the lack of impact metrics. This is perhaps even more notable in regards to Instagram, a platform that has received comparatively little discussion in academic research more broadly.Instagram as Social MediaInstagram is a photo sharing application that launched in 2010 and has seen significant uptake by users in that time, reaching 700 million monthly active users as of April 2017 (Instagram “700 Million”). Recent additions to the service, such as the “Snapchat clone” Instagram Stories, appear to have helped boost growth (Constine, para 4). Instagram then is a major player in the social media user market, and the emergence of academic research into the platform reflect this. Early investigations include Manikonda, Hu and Kambhampati’s analysis social networks, demographics, and activities of users in which they identified some clear differences in usage compared to Flickr (another photo-sharing network) and Twitter (5). Hochman and Manovich and Hochman and Schwartz examined what information visualisations generated from Instagram images can reveal about the “visual rhythms” of geographical locations such as New York City.To provide context for the use of Instagram as a way of disseminating research through a more curated, visual approach, this section will examine professional uses of Instagram, the role of Influencers, and some of the functionalities of the platform.Instagram is now a platform that caters for both personal and professional accounts. The user-interface allows for a streamlined and easily navigable process from taking a photo, adding filters or effects, and sharing the photo instantly. The platform has developed to include web-based access to complement the mobile application, and has also introduced Instagram Business accounts, which provide “real-time metrics”, “insights into your followers”, and the ability to “add information about your company” (Instagram “Instagram Business”). This also comes with the option to pay for advertisements.Despite its name, many users of Instagram, especially those with profiles that are professional or business orientated, do not only produce instant content. While the features of Instagram, such as geotagging, timestamping, and the ability to use the camera from within the app, lend themselves to users capturing their everyday experience in the moment, more and more content is becoming carefully curated. As such, some accounts are blurring the line between personal and professional, becoming what Crystal Abidin calls Influencers, identifying the practice as when microcelebrities are able to use the “textual and visual narration of their personal, everyday lives” to generate paid advertorials (86). One effect of this, as Abidin investigates in the context of Singapore and the #OOTD (Outfit of the Day) hashtag, is the way “everyday Instagram users are beginning to model themselves after Influences” and therefore generate advertising content “that is not only encouraged by Influences and brands but also publicly utilised without remuneration” (87). Instagram, then, can be a very powerful platform for businesses to reach wide audiences, and the flexibility of caption length and visual content provides a type of viral curation practice as in the case of the #OOTD hashtag following.Considering the focus of my #AustralianBeachspace project on Australian beaches, many of the Instagram accounts and hashtags I encountered and engaged with were tourism related. Although this will be discussed in more detail below, it is worth noting that individual Influencers exist in these fields as well and often provide advertorial content for companies like accommodation chains or related products. One example is user @katgaskin, an Influencer who both takes photos, features in photos, and provides “organic” adverts for products and services (see image). Not all her photos are adverts; some are beach or ocean images without any advertorial content in the caption. In this instance, the use of distinctive photo editing, iconic imagery (the “salty pineapple” branding), and thematic content of beach and ocean landscapes, makes for a recognisable and curated aesthetic. Figure 1: An example from user @katgaskin's Instagram profile that includes a mention of a product. Image sourced from @katgaskin, uploaded 2 June 2017.@katgaskin’s profile’s aesthetic identity is, as such, linked with the ocean and the beach. Although her physical location regularly changes (her profile includes images from, for example, Nicaragua, Australia, and the United States), the thematic link is geographical. And research suggests the visual focus of Instagram lends itself to place-based content. As Hochman and Manovich state:While Instagram eliminates static timestamps, its interface strongly emphasizes physical place and users’ locations. The application gives a user the option to publicly share a photo’s location in two ways. Users can tag a photo to a specific venue, and then view all other photos that were taken and tagged there. If users do not choose to tag a photo to a venue, they can publically share their photos’ location information on a personal ‘photo-map’, displaying all photos on a zoomable word map. (para 14)This means that the use of place in the app is anchored to the visual content, not the uploader’s location. While it is possible to consider Instagram’s intention was to anchor the content and the uploader’s location together (as in the study conducted by Weilenmann, Hillman, and Jungselius that explored how Instagram was used in the museum), this is no longer always the case. In this way, Instagram is also providing a platform for more serious photographers to share their images after they have processed and edited them and connect the image with the image content rather than the uploader’s position.This place-based focus also shares origins in tourism photography practices. For instance, Kibby’s analysis of the use of Instagram as a method for capturing the “tourist gaze” in Monument Valley notes that users mostly wanted to capture the “iconic” elements of the site (most of which were landscape formations made notable through representations in popular culture).Another area of research into Instagram use is hashtag practice (see, for example, Ferrara, Interdonato, and Tagarelli). Highfield and Leaver have generated a methodology for mapping hashtags and analysing the information this can reveal about user practices. Many Instagram accounts use hashtags to provide temporal or place based information, some specific (such as #sunrise or #newyorkcity) and some more generic (such as #weekend or #beach). Of particular relevance here is the role hashtags play in generating higher levels of user engagement. It is also worth noting the role of “algorithmic personalization” introduced by Instagram earlier in 2017 and the lukewarm user response as identified by Mahnke Skrubbeltrang, Grunnet, and Tarp’s analysis, suggesting “users are concerned with algorithms dominating their experience, resulting in highly commercialised experience” (section 7).Another key aspect of Instagram’s functionality is linked to the aesthetic of the visual content: photographic filters. Now a mainstay of other platforms such as Facebook and Twitter, Instagram popularised the use of filters by providing easily accessible options within the app interface directly. Now, other apps such as VCSO allow for more detailed editing of images that can then be imported into Instagram; however, the pre-set filters have proven popular with large numbers of users. A study in 2014 by Araújo, Corrêa, da Silva et al found 76% of analysed images had been processed in some way.By considering the professional uses of Instagram and the functionality of the app (geotagging; hashtagging; and filters), it is possible to summarise Instagram as a social media platform that, although initially perhaps intended to capture the everyday visual experiences of amateur photographers using their smart phone, has adapted to become a network for sharing images that can be for both personal and professional purposes. It has a focus on place, with its geotagging capacity and hashtag practices, and can include captions The #AustralianBeachspace ProjectIn October 2016, I began a social media project called #AustralianBeachspace that was designed to showcase content from my PhD thesis and ongoing work into representations of Australian beaches in popular culture (a collection of the project posts only, as opposed to the ongoing Instagram profile, can be found here). The project was envisaged as a three month project; single posts (including an image and caption) were planned and uploaded six times a week (every day except Sundays). Although I have occasionally continued to use the hashtag since the project’s completion (on 24 Dec. 2016), the frequency and planned nature of the posts since then has significantly changed. What has not changed is the strong thematic through line of my posts, all of which continue to rely heavily on beach imagery. This is distinct from other academic social media use which if often more focused on the everyday activity of academia.Instagram was my social media choice for this project for two main reasons: I had no existing professional Instagram profile (unlike Twitter) and thus I could curate a complete project in isolation, and the subject of my PhD thesis was representations of Australian beaches in literature and film. As such, my research was appropriate for, and in fact was augmented by, visual depiction. It is also worth noting the tendency reported by myself and others (Huntsman; Booth) of academics not considering the beach an area worthy of focus. This resonates with Bech Albrechtslund and Albrechtslund’s argument that “social media practices associated with leisure and playfulness” are still meaningful and worthy of examination.Up until this point, my research outputs had been purely textual. I, therefore, needed to generate a significant number of visual elements to complement the vast amount of textual content already created. I used my PhD thesis to provide the thematic structure (I have detailed this process in more depth here), and then used the online tool Trello to plan, organise, and arrange the intended posts (image and caption). The project includes images taken by myself, my partner, and other images with no copyright limitations attached as sourced through photo sharing sites like Unsplash.com.The images were all selected because of their visual representation of an Australian beach, and the alignment of the image with the themes of the project. For instance, one theme focused on the under-represented negative aspects of the beach. One image used in this theme was a photo of Bondi Beach ocean pool, empty at night. I carefully curated the images and arranged them according to the thematic schedule (as can be seen below) and then wrote the accompanying textual captions. Figure 2: A sample of the schedule used for the posting of curated images and captions.While there were some changes to the schedule throughout (for instance, my attendance at the 2016 Sculpture by the Sea exhibition prompted me to create a sixth theme), the process of content curation and creation remained the same.Visual curation of the images was a particularly important aspect of the project, and I did use an external photo processing application to create an aesthetic across the collection. As Kibby notes, “photography is intrinsically linked with tourism” (para 9), and although not a tourism project inherently, #AustralianBeachspace certainly engaged with touristic tropes by focusing on Australian beaches, an iconic part of Australian national and cultural identity (Ellison 2017; Ellison and Hawkes 2016; Fiske, Hodge, and Turner 1987). However, while beaches are perhaps instinctively touristic in their focus on natural landscapes, this project was attempting to illustrate more complexity in this space (which mirrors an intention of my PhD thesis). As such, some images were chosen because of their “ordinariness” or their subversion of the iconic beach images (see below). Figures 3 and 4: Two images that capture some less iconic images of Australian beaches; one that shows an authentic, ordinary summer's day and another that shows an empty beach during winter.I relied on captions to provide the textual information about the image. I also included details about the photographer where possible, and linked all the images with the hashtag #AustralianBeachspace. The textual content, much of which emerged from ongoing and extensive research into the topic, was somewhat easier to collate. However, it required careful reworking and editing to suit the desired audience and to work in conjunction with the image. I kept captions to the approximate length of a paragraph and concerned with one point. This process forced me to distil ideas and concepts into short chunks of writing, which is distinct from other forms of academic output. This textual content was designed to be accessible beyond an academic audience, but still used a relatively formal voice (especially in comparison to more personal users of the platform).I provided additional hashtags in a first comment, which were intended to generate some engagement. Notably, these hashtags were content related (such as #beach and #surf; they were not targeting academic hashtags). At time of writing, my follower count is 70. The most liked (or “favourited”) photo from the project received 50 likes, and the most comments received was 6 (on a number of posts). Some photos published since the end of the project have received higher numbers of likes and comments. This certainly does not suggest enormous impact from this project. Hashtags utilised in this project were adopted from popular and related hashtags using the analytics tool Websta.me as well as hashtags used in similar content styled profiles, such as: #seeaustralia #thisisqueensland #visitNSW #bondibeach #sunshinecoast and so on. Notably, many of the hashtags were place-based. The engagement of this project with users beyond academia was apparent: followers and comments on the posts are more regularly from professional photographers, tourism bodies, or location-based businesses. In fact, because of the content or place-based hashtagging practices I employed, it was difficult to attract an academic audience at all. However, although the project was intended as an experiment with public facing research dissemination, I did not actively adopt a stringent engagement strategy and have not kept metrics per day to track engagement. This is a limitation of the study and undoubtedly allows scope for further research.ConclusionInstagram is a platform that does not have clear pathways for reaching academic audiences in targeted ways. At this stage, little research has emerged that investigates Instagram use among academics, although it is possible to presume there are similarities with blogging or Twitter (for example, conference posting and making connections with colleagues).However, the functionality of Instagram does lend itself to creating and curating aesthetically interesting ways of disseminating, and in fact representing, research. Ideas and findings must be depicted as images and captions, and the curatorial process of marrying visual images to complement or support textual information can make for more accessible and palatable content. Perhaps most importantly, the content is freely accessible and not locked behind paywalls or expensive academic publications. It can also be easily archived and shared.The #AustralianBeachspace project is small-scale and not indicative of widespread academic practice. However, examining the process of creating the project and the role Instagram may play in potentially reaching a more diverse, public audience for academic research suggests scope for further investigation. Although not playing an integral role in publication metrics and traditional measures of research impact, the current changing climate of higher education policy provides motivations to continue exploring non-traditional methods for disseminating research findings and tracking research engagement and impact.Instagram functions as a useful platform for sharing research data through a curated collection of images and captions. Rather than being a space for instant updates on the everyday life of the academic, it can also function in a more aesthetically interesting and dynamic way to share research findings and possibly generate wider, public-facing engagement for topics less likely to emerge from behind the confines of academic journal publications.

Work described in this thesis contains the results on the study of volatile organic compounds (VOCs) in landfill gas from seven landfill sites in the western region of Melbourne, Victoria, Australia. Sampling methods including sampling with adsorption tubes, tedlar bags and cryogenic trapping were investigated and analytical systems were developed using adsorption tubes with solvent or thermal desorption followed by analysis of VOCs using gas chromatography with mass selective detection (GC/MS).

Composting of biodegradable waste is an effective means of reducing landfill garbage and improving the state of our environment. The widespread adoption of this behaviour by community members is subject to various social psychological processes. Table top signs outlining a pro-composting injunctive norm, and models demonstrating the behaviour (descriptive norm) were employed in two shopping centre food courts and a fast food restaurant to attempt to increase the use of public compost bins. When diners viewed models composting ahead of them, they were more likely to compost as well. However, the signs had no effect on composting rates, either alone or in combination with the models. Results support the idea that behaving in a pro-environmental manner around others can have an influence on them to behave pro-environmentally as well.
