AbstractObjectivesTo estimate the dietary intakes of heterocyclic amines (HCAs), to examine the intakes in relation to socio-economics, lifestyle and other dietary factors and to compare the classification of subjects by intake of HCA versus intake of meat and fish.DesignCross-sectional analysis within the Malmö Diet and Cancer (MDC) cohort. Data were obtained from a modified diet history, a structured questionnaire on socio-economics and lifestyle, anthropometric measurements and chemical analysis of HCAs. HCA intake was cross-classified against meat and fish intake. The likelihood of being a high consumer of HCAs was estimated by logistic regression analysis. Dietary intakes were examined across quintiles of HCA intake using analysis of variance.SettingBaseline examinations conducted in 1991–1994 in Malmö, Sweden.SubjectsA sub-sample of 8599 women and 6575 men of the MDC cohort.ResultsThe mean daily HCA intake was 583 ng for women and 821 ng for men. Subjects were ranked differently with respect to HCA intake compared with intake of fried and baked meat and fish (κ = 0.13). High HCA intake was significantly associated with lower age, overweight, sedentary lifestyle and smoking. Intakes of dietary fibre, fruits and fermented milk products were negatively associated with HCA intake, while intakes of selenium, vegetables, potatoes, alcohol (among men) and non-milk-based margarines (among women) were positively associated with HCA intake.ConclusionsThe estimated daily HCA intake of 690 ng is similar to values obtained elsewhere. The present study suggests that lifestyle factors (e.g. smoking, physical activity, fruit and vegetable intakes, and types of milk products and margarines) may confound associations between HCA intake and disease. The poor correlation between HCA intake and intakes of fried meat and fish facilitates an isolation of the health effects of HCAs.

This paper argues that artist Dope Saint Jude is transforming South African hip-hop by queering a genre that has predominantly been male and heteronormative. Specifically, I analyse the opening skit of her music video “Keep in Touch” in order to unpack the ways which she revives Gayle, a gay language that adopted double-coded forms of speech during the apartheid era—a context in which homosexuals were criminalised. The use of Gayle and spaces close to the city centre of Cape Town (such as Salt River and Woodstock) speaks to the city as it was before it was transformed by the decline of industries due to the country’s adoption of neoliberal economics and, more recently, by the gentrification of these spaces. Dope Saint Jude therefore reclaims these city spaces through her use of gay modes of speech that have a long history in Cape Town and by positioning her work as hip-hop, which has been popular in the city for well over two decades. Her inclusion of transgender MC and DJ Angel Ho pushes the boundaries of hegemonic and binary conceptions of gender identity even further. In essence, Dope Saint Jude is transforming local hip-hop in a context that is shaped significantly by US cultural imperialism. The artist is also transforming our perspective of spaces that have been altered by neoliberal economics.Setting the SceneDope Saint Jude (DSJ) is a queer MC from Elsies River, a working class township located on Cape Town's Cape Flats in South Africa. Elsies River was defined as a “coloured” neighbourhood under the apartheid state's Group Areas Act, which segregated South Africans racially. With the aid of the Population Registration Act, citizens were classified, not merely along the lines of white, Asian, or black—black subjects were also divided into further categories. The apartheid state also distinguished between black and “coloured” subjects. Michael MacDonald contends that segregation “ordained blacks to be inferior to whites; apartheid cast them to be indelibly different” (11). Apartheid declared “African claims in South Africa to be inferior to white claims” and effectively claimed that black subjects “belonged elsewhere, in societies of their own, because their race was different” (ibid). The term “coloured” defined people as “mixed race” to separate communities that might otherwise have identified as black in the broad and inclusive sense (Erasmus 16). Racial categorisation was used to create a racial hierarchy with white subjects at the top of that hierarchy and those classified as black receiving the least resources and benefits. This frustrated attempts to establish broad alliances of black struggles against apartheid. It is in this sense that race is socially and politically constructed and continues to have currency, despite the fact that biologically essentialist understandings of race have been discredited (Yudell 13–14). Thanks to apartheid town planning and resource allocation, many townships on the Cape Flats were poverty-stricken and plagued by gang violence (Salo 363). This continues to be the case because post-apartheid South Africa's embrace of neoliberal economics failed to address racialised class inequalities significantly (Haupt, Static 6–8). This is the '90s context in which socially conscious hip-hop crews, such as Prophets of da City or Black Noise, came together. They drew inspiration from Black Consciousness philosophy via their exposure to US hip-hop crews such as Public Enemy in order to challenge apartheid policies, including their racial interpellation as “coloured” as distinct from the more inclusive category, black (Haupt, “Black Thing” 178). Prophets of da City—whose co-founding member, Shaheen Ariefdien, also lived in Elsies River—was the first South African hip-hop outfit to record an album. Whilst much of their work was performed in English, they quickly transformed the genre by rapping in non-standard varieties of Afrikaans and by including MCs who rap in African languages (ibid). They therefore succeeded in addressing key issues related to race, language, and class disparities in relation to South Africa's transition to democracy (Haupt, “Black Thing”; Haupt, Stealing Empire). However, as is the case with mainstream US hip-hop, specifically gangsta rap (Clay 149), South African hip-hop has been largely dominated by heterosexual men. This includes the more commercial hip-hop scene, which is largely perceived to be located in Johannesburg, where male MCs like AKA and Cassper Nyovest became celebrities. However, certain female MCs have claimed the genre, notably EJ von Lyrik and Burni Aman who are formerly of Godessa, the first female hip-hop crew to record and perform locally and internationally (Haupt, Stealing Empire 166; Haupt, “Can a Woman in Hip-Hop”). DSJ therefore presents the exception to a largely heteronormative and male-dominated South African music industry and hip-hop scene as she transforms it with her queer politics. While queer hip-hop is not new in the US (Pabón and Smalls), this is new territory for South Africa. Writing about the US MC Jean Grae in the context of a “male-dominated music industry and genre,” Shanté Paradigm Smalls contends,Heteronormativity blocks the materiality of the experiences of Black people. Yet, many Black people strive for a heteronormative effect if not “reality”. In hip hop, there is a particular emphasis on maintaining the rigidity of categories, even if those categories fail [sic]. (87) DSJ challenges these rigid categories. Keep in TouchDSJ's most visible entry onto the media landscape to date has been her appearance in an H&M recycling campaign with British Sri Lankan artist MIA (H&M), some fashion shoots, her new EP—Reimagine (Dope Saint Jude)—and recent Finnish, US and French tours as well as her YouTube channel, which features her music videos. As the characters’ theatrical costumes suggest, “Keep in Touch” is possibly the most camp and playful music video she has produced. It commences somewhat comically with Dope Saint Jude walking down Salt River main road to a public telephone, where she and a young woman in pig tails exchange dirty looks. Salt River is located at the foot of Devil's Peak not far from Cape Town's CBD. Many factories were located there, but the area is also surrounded by low-income housing, which was designated a “coloured” area under apartheid. After apartheid, neighbourhoods such as Salt River, Woodstock, and the Bo-Kaap became increasingly gentrified and, instead of becoming more inclusive, many parts of Cape Town continued to be influenced by policies that enable racialised inequalities. Dope Saint Jude calls Angel Ho: DSJ: Awêh, Angie! Yoh, you must check this kak sturvy girl here by the pay phone. [Turns to the girl, who walks away as she bursts a chewing gum bubble.] Ja, you better keep in touch. Anyway, listen here, what are you wys?Angel Ho: Ah, just at the salon getting my hair did. What's good? DSJ: Wanna catch on kak today?Angel Ho: Yes, honey. But, first, let me Gayle you this. By the jol by the art gallery, this Wendy, nuh. This Wendy tapped me on the shoulder and wys me, “This is a place of decorum.”DSJ: What did she wys?Angel Ho: De-corum. She basically told me this is not your house. DSJ: I know you told that girl to keep in touch!Angel Ho: Yes, Mama! I'm Paula, I told that bitch, “Keep in touch!” [Points index finger in the air.](Saint Jude, Dope, “Keep in Touch”)Angel Ho's name is a play on the male name Angelo and refers to the trope of the ho (whore) in gangsta rap lyrics and in music videos that present objectified women as secondary to male, heterosexual narratives (Sharpley-Whiting 23; Collins 27). The queering of Angelo, along with Angel Ho’s non-binary styling in terms of hair, make-up, and attire, appropriates a heterosexist, sexualised stereotype of women in order to create room for a gender identity that operates beyond heteronormative male-female binaries. Angel Ho’s location in a hair salon also speaks to stereotypical associations of salons with women and gay subjects. In a discussion of gender stereotypes about hair salons, Kristen Barber argues that beauty work has traditionally been “associated with women and with gay men” and that “the body beautiful has been tightly linked to the concept of femininity” (455–56). During the telephonic exchange, Angel Ho and Dope Saint Jude code-switch between standard and non-standard varieties of English and Afrikaans, as the opening appellation, “Awêh,” suggests. In this context, the term is a friendly greeting, which intimates solidarity. “Sturvy” means pretentious, whilst “kak” means shit, but here it is used to qualify “sturvy” and means that the girl at the pay phone is very pretentious or “full of airs.” To be “wys” means to be wise, but it can also mean that you are showing someone something or educating them. The meanings of these terms shift, depending on the context. The language practices in this skit are in line with the work of earlier hip-hop crews, such as Prophets of da City and Brasse vannie Kaap, to validate black, multilingual forms of speech and expression that challenge the linguistic imperialism of standard English and Afrikaans in South Africa, which has eleven official languages (Haupt, “Black Thing”; Haupt, Stealing Empire; Williams). Henry Louis Gates’s research on African American speech varieties and literary practices emerging from the repressive context of slavery is essential to understanding hip-hop’s language politics. Hip-hop artists' multilingual wordplay creates parallel discursive universes that operate both on the syntagmatic axis of meaning-making and the paradigmatic axis (Gates 49; Haupt, “Stealing Empire” 76–77). Historically, these discursive universes were those of the slave masters and the slaves, respectively. While white hegemonic meanings are produced on the syntagmatic axis (which is ordered and linear), black modes of speech as seen in hip-hop word play operate on the paradigmatic axis, which is connotative and non-linear (ibid). Distinguishing between Signifyin(g) / Signification (upper case, meaning black expression) and signification (lower case, meaning white dominant expression), he argues that “the signifier ‘Signification’ has remained identical in spelling to its white counterpart to demonstrate [. . .] that a simultaneous, but negated, parallel discursive (ontological, political) universe exists within the larger white discursive universe” (Gates 49). The meanings of terms and expressions can change, depending on the context and manner in which they are used. It is therefore the shared experiences of speech communities (such as slavery or racist/sexist oppression) that determine the negotiated meanings of certain forms of expression. Gayle as a Parallel Discursive UniverseDSJ and Angel Ho's performance of Gayle takes these linguistic practices further. Viewers are offered points of entry into Gayle via the music video’s subtitles. We learn that Wendy is code for a white person and that to keep in touch means exactly the opposite. Saint Jude explains that Gayle is a very fun queer language that was used to kind of mask what people were saying [. . .] It hides meanings and it makes use of women's names [. . . .] But the thing about Gayle is it's constantly changing [. . .] So everywhere you go, you kind of have to pick it up according to the context that you're in. (Ovens, Saint Jude and Haupt)According to Kathryn Luyt, “Gayle originated as Moffietaal [gay language] in the coloured gay drag culture of the Western Cape as a form of slang amongst Afrikaans-speakers which over time, grew into a stylect used by gay English and Afrikaans-speakers across South Africa” (Luyt 8; Cage 4). Given that the apartheid state criminalised homosexuals, Gayle was coded to evade detection and to seek out other members of this speech community (Luyt 8). Luyt qualifies the term “language” by arguing, “The term ‘language’ here, is used not as a constructed language with its own grammar, syntax, morphology and phonology, but in the same way as linguists would discuss women’s language, as a way of speaking, a kind of sociolect” (Luyt 8; Cage 1). However, the double-coded nature of Gayle allows one to think of it as creating a parallel discursive universe as Gates describes it (49). Whereas African American and Cape Flats discursive practices function parallel to white, hegemonic discourses, gay modes of speech run parallel to heteronormative communication. Exclusion and MicroaggressionsThe skit brings both discursive practices into play by creating room for one to consider that DSJ queers a male-dominated genre that is shaped by US cultural imperialism (Haupt, Stealing Empire 166) as a way of speaking back to intersectional forms of marginalisation (Crenshaw 1244), which are created by “white supremacist capitalist patriarchy” (hooks 116). This is significant in South Africa where “curative rape” of lesbians and other forms of homophobic violence are prominent (cf. Gqola; Hames; Msibi). Angel Ho's anecdote conveys a sense of the extent to which black individuals are subject to scrutiny. Ho's interpretation of the claim that the gallery “is a place of decorum” is correct: it is not Ho's house. Black queer subjects are not meant to feel at home or feel a sense of ownership. This functions as a racial microaggression: “subtle insults (verbal, nonverbal, and/or visual) directed toward people of color, often automatically or unconsciously” (Solorzano, Ceja, and Yosso 60). This speaks to DSJ's use of Salt River, Woodstock, and Bo-Kaap for the music video, which features black queer bodies in performance—all of these spaces are being gentrified, effectively pushing working class people of colour out of the city (cf. Didier, Morange, and Peyroux; Lemanski). Gustav Visser explains that gentrification has come to mean a unit-by-unit acquisition of housing which replaces low-income residents with high-income residents, and which occurs independent of the structural condition, architecture, tenure or original cost level of the housing (although it is usually renovated for or by the new occupiers). (81–82) In South Africa this inequity plays out along racial lines because its neoliberal economic policies created a small black elite without improving the lives of the black working class. Instead, the “new African bourgeoisie, because it shares racial identities with the bulk of the poor and class interests with white economic elites, is in position to mediate the reinforcing cleavages between rich whites and poor blacks without having to make more radical changes” (MacDonald 158). In a news article about a working class Salt River family of colour’s battle against an eviction, Christine Hogg explains, “Gentrification often means the poor are displaced as the rich move in or buildings are upgraded by new businesses. In Woodstock and Salt River both are happening at a pace.” Angel Ho’s anecdote, as told from a Woodstock hair salon, conveys a sense of what Woodstock’s transformation from a coloured, working class Group Area to an upmarket, trendy, and arty space would mean for people of colour, including black, queer subjects. One could argue that this reading of the video is undermined by DSJ’s work with global brand H&M. Was she was snared by neoliberal economics? Perhaps, but one response is that the seeds of any subculture’s commercial co-option lie in the fact it speaks through commodities (for example clothing, make-up, CDs, vinyl, or iTunes / mp3 downloads (Hebdige 95; Haupt, Stealing Empire 144–45). Subcultures have a window period in which to challenge hegemonic ideologies before they are delegitimated or commercially co-opted. Hardt and Negri contend that the means that extend the reach of corporate globalisation could be used to challenge it from within it (44–46; Haupt, Stealing Empire 26). DSJ utilises her H&M work, social media, the hip-hop genre, and international networks to exploit that window period to help mainstream black queer identity politics.ConclusionDSJ speaks back to processes of exclusion from the city, which was transformed by apartheid and, more recently, gentrification, by claiming it as a creative and playful space for queer subjects of colour. She uses Gayle to lay claim to the city as it has a long history in Cape Town. In fact, she says that she is not reviving Gayle, but is simply “putting it on a bigger platform” (Ovens, Saint Jude, and Haupt). The use of subtitles in the video suggests that she wants to mainstream queer identity politics. Saint Jude also transforms hip-hop heteronormativity by queering the genre and by locating her work within the history of Cape hip-hop’s multilingual wordplay.

IntroductionTasmania hangs from the map of Australia like a drop in freefall from the substance of the mainland. Often the whole state is mislaid from Australian maps and logos (Reddit). Tasmania has, at least since federation, been considered peripheral—a region seen as isolated, a ‘problem’ economically, politically, and culturally. However, Tasmania not only cleaves to the ‘north island’ of Australia but is also subject to the gravitational pull of an even greater land mass—Antarctica. In this article, we upturn the political conventions of map-making that place both Antarctica and Tasmania in obscure positions at the base of the globe. We show how a changing global climate re-frames Antarctica and the Southern Ocean as key drivers of worldwide environmental shifts. The liquid and solid water between Tasmania and Antarctica is revealed not as a homogenous barrier, but as a dynamic and relational medium linking the Tasmanian archipelago with Antarctica. When Antarctica becomes the focus, the script is flipped: Tasmania is no longer on the edge, but core to a network of gateways into the southern land. The state’s capital of Hobart can from this perspective be understood as an “Antarctic city”, central to the geopolitics, economy, and culture of the frozen continent (Salazar et al.). Viewed from the south, we argue, Tasmania is not a problem, but an opportunity for a form of ecological, cultural, economic, and political sustainability that opens up the southern continent to science, discovery, and imagination.A Centre at the End of the Earth? Tasmania as ParadoxThe islands of Tasmania owe their existence to climate change: a period of warming at the end of the last ice age melted the vast sheets of ice covering the polar regions, causing sea levels to rise by more than one hundred metres (Tasmanian Climate Change Office 8). Eleven thousand years ago, Aboriginal people would have witnessed the rise of what is now called Bass Strait, turning what had been a peninsula into an archipelago, with the large island of Tasmania at its heart. The heterogeneous practices and narratives of Tasmanian regional identity have been shaped by the geography of these islands, and their connection to the Southern Ocean and Antarctica. Regions, understood as “centres of collective consciousness and sociospatial identities” (Paasi 241) are constantly reproduced and reimagined through place-based social practices and communications over time. As we will show, diverse and contradictory narratives of Tasmanian regionality often co-exist, interacting in complex and sometimes complementary ways. Ecocritical literary scholar C.A. Cranston considers duality to be embedded in the textual construction of Tasmania, writing “it was hell, it was heaven, it was penal, it was paradise” (29). Tasmania is multiply polarised: it is both isolated and connected; close and far away; rich in resources and poor in capital; the socially conservative birthplace of radical green politics (Hay 60). The weather, as if sensing the fine balance of these paradoxes, blows hot and cold at a moment’s notice.Tasmania has wielded extraordinary political influence at times in its history—notably during the settlement of Melbourne in 1835 (Boyce), and during protests against damming the Franklin River in the early 1980s (Mercer). However, twentieth-century historical and political narratives of Tasmania portray the Bass Strait as a barrier, isolating Tasmanians from the mainland (Harwood 61). Sir Bede Callaghan, who headed one of a long line of federal government inquiries into “the Tasmanian problem” (Harwood 106), was clear that Tasmania was a victim of its own geography:the major disability facing the people of Tasmania (although some residents may consider it an advantage) is that Tasmania is an island. Separation from the mainland adversely affects the economy of the State and the general welfare of the people in many ways. (Callaghan 3)This perspective may stem from the fact that Tasmania has maintained the lowest Gross Domestic Product per capita of all states since federation (Bureau of Infrastructure Transport and Regional Economics 9). Socially, economically, and culturally, Tasmania consistently ranks among the worst regions of Australia. Statistical comparisons with other parts of Australia reveal the population’s high unemployment, low wages, poor educational outcomes, and bad health (West 31). The state’s remoteness and isolation from the mainland states and its reliance on federal income have contributed to the whole of Tasmania, including Hobart, being classified as ‘regional’ by the Australian government, in an attempt to promote immigration and economic growth (Department of Infrastructure and Regional Development 1). Tasmania is indeed both regional and remote. However, in this article we argue that, while regionality may be cast as a disadvantage, the island’s remote location is also an asset, particularly when viewed from a far southern perspective (Image 1).Image 1: Antarctica (Orthographic Projection). Image Credit: Wikimedia Commons, Modified Shading of Tasmania and Addition of Captions by H. Nielsen.Connecting Oceans/Collapsing DistanceTasmania and Antarctica have been closely linked in the past—the future archipelago formed a land bridge between Antarctica and northern land masses until the opening of the Tasman Seaway some 32 million years ago (Barker et al.). The far south was tangible to the Indigenous people of the island in the weather blowing in from the Southern Ocean, while the southern lights, or “nuyina”, formed a visible connection (Australia’s new icebreaker vessel is named RSV Nuyina in recognition of these links). In the contemporary Australian imagination, Tasmania tends to be defined by its marine boundaries, the sea around the islands represented as flat, empty space against which to highlight the topography of its landscape and the isolation of its position (Davies et al.). A more relational geographic perspective illuminates the “power of cross-currents and connections” (Stratford et al. 273) across these seascapes. The sea country of Tasmania is multiple and heterogeneous: the rough, shallow waters of the island-scattered Bass Strait flow into the Tasman Sea, where the continental shelf descends toward an abyssal plain studded with volcanic seamounts. To the south, the Southern Ocean provides nutrient-rich upwellings that attract fish and cetacean populations. Tasmania’s coast is a dynamic, liminal space, moving and changing in response to the global currents that are driven by the shifting, calving and melting ice shelves and sheets in Antarctica.Oceans have long been a medium of connection between Tasmania and Antarctica. In the early colonial period, when the seas were the major thoroughfares of the world and inland travel was treacherous and slow, Tasmania’s connection with the Southern Ocean made it a valuable hub for exploration and exploitation of the south. Between 1642 and 1900, early European explorers were followed by British penal colonists, convicts, sealers, and whalers (Kriwoken and Williamson 93). Tasmania was well known to polar explorers, with expeditions led by Jules Dumont d’Urville, James Clark Ross, Roald Amundsen, and Douglas Mawson all transiting through the port of Hobart. Now that the city is no longer a whaling hub, growing populations of cetaceans continue to migrate past the islands on their annual journeys from the tropics, across the Sub-Antarctic Front and Antarctic circumpolar current, and into the south polar region, while southern species such as leopard seals are occasionally seen around Tasmania (Tasmania Parks and Wildlife). Although the water surrounding Tasmania and Antarctica is at times homogenised as a ‘barrier’, rendering these places isolated, the bodies of water that surround both are in fact permeable, and regularly crossed by both humans and marine species. The waters are diverse in their physical characteristics, underlying topography, sea life, and relationships, and serve to connect many different ocean regions, ecosystems, and weather patterns.Views from the Far SouthWhen considered in terms of its relative proximity to Antarctic, rather than its distance from Australia’s political and economic centres, Tasmania’s identity undergoes a significant shift. A sign at Cockle Creek, in the state’s far south, reminds visitors that they are closer to Antarctica than to Cairns, invoking a discourse of connectedness that collapses the standard ten-day ship voyage to Australia’s closest Antarctic station into a unit comparable with the routinely scheduled 5.5 hour flight to North Queensland. Hobart is the logistical hub for the Australian Antarctic Division and the French Institut Polaire Francais (IPEV), and has hosted Antarctic vessels belonging to the USA, South Korea, and Japan in recent years. From a far southern perspective, Hobart is not a regional Australian capital but a global polar hub. This alters the city’s geographic imaginary not only in a latitudinal sense—from “top down” to “bottom up”—but also a longitudinal one. Via its southward connection to Antarctica, Hobart is also connected east and west to four other recognized gateways: Cape Town in South Africa, Christchurch in New Zealand; Punta Arenas in Chile; and Ushuaia in Argentina (Image 2). The latter cities are considered small by international standards, but play an outsized role in relation to Antarctica.Image 2: H. Nielsen with a Sign Announcing Distances between Antarctic ‘Gateway’ Cities and Antarctica, Ushuaia, Argentina, 2018. Image Credit: Nicki D'Souza.These five cities form what might be called—to adapt geographer Klaus Dodds’ term—a ‘Southern Rim’ around the South Polar region (Dodds Geopolitics). They exist in ambiguous relationship to each other. Although the five cities signed a Statement of Intent in 2009 committing them to collaboration, they continue to compete vigorously for northern hemisphere traffic and the brand identity of the most prominent global gateway. A state government brochure spruiks Hobart, for example, as the “perfect Antarctic Gateway” emphasising its uniqueness and “natural advantages” in this regard (Tasmanian Government, 2016). In practice, the cities are automatically differentiated by their geographic position with respect to Antarctica. Although the ‘ice continent’ is often conceived as one entity, it too has regions, in both scientific and geographical senses (Terauds and Lee; Antonello). Hobart provides access to parts of East Antarctica, where the Australian, French, Japanese, and Chinese programs (among others) have bases; Cape Town is a useful access point for Europeans going to Dronning Maud Land; Christchurch is closest to the Ross Sea region, site of the largest US base; and Punta Arenas and Ushuaia neighbour the Antarctic Peninsula, home to numerous bases as well as a thriving tourist industry.The Antarctic sector is important to the Tasmanian economy, contributing $186 million (AUD) in 2017/18 (Wells; Gutwein; Tasmanian Polar Network). Unsurprisingly, Tasmania’s gateway brand has been actively promoted, with the 2016 Australian Antarctic Strategy and 20 Year Action Plan foregrounding the need to “Build Tasmania’s status as the premier East Antarctic Gateway for science and operations” and the state government releasing a “Tasmanian Antarctic Gateway Strategy” in 2017. The Chinese Antarctic program has been a particular focus: a Memorandum of Understanding focussed on Australia and China’s Antarctic relations includes a “commitment to utilise Australia, including Tasmania, as an Antarctic ‘gateway’.” (Australian Antarctic Division). These efforts towards a closer relationship with China have more recently come under attack as part of a questioning of China’s interests in the region (without, it should be noted, a concomitant questioning of Australia’s own considerable interests) (Baker 9). In these exchanges, a global power and a state of Australia generally classed as regional and peripheral are brought into direct contact via the even more remote Antarctic region. This connection was particularly visible when Chinese President Xi Jinping travelled to Hobart in 2014, in a visit described as both “strategic” and “incongruous” (Burden). There can be differences in how this relationship is narrated to domestic and international audiences, with issues of sovereignty and international cooperation variously foregrounded, laying the ground for what Dodds terms “awkward Antarctic nationalism” (1).Territory and ConnectionsThe awkwardness comes to a head in Tasmania, where domestic and international views of connections with the far south collide. Australia claims sovereignty over almost 6 million km2 of the Antarctic continent—a claim that in area is “roughly the size of mainland Australia minus Queensland” (Bergin). This geopolitical context elevates the importance of a regional part of Australia: the claims to Antarctic territory (which are recognised only by four other claimant nations) are performed not only in Antarctic localities, where they are made visible “with paraphernalia such as maps, flags, and plaques” (Salazar 55), but also in Tasmania, particularly in Hobart and surrounds. A replica of Mawson’s Huts in central Hobart makes Australia’s historic territorial interests in Antarctica visible an urban setting, foregrounding the figure of Douglas Mawson, the well-known Australian scientist and explorer who led the expeditions that proclaimed Australia’s sovereignty in the region of the continent roughly to its south (Leane et al.). Tasmania is caught in a balancing act, as it fosters international Antarctic connections (such hosting vessels from other national programs), while also playing a key role in administering what is domestically referred to as the Australian Antarctic Territory. The rhetoric of protection can offer common ground: island studies scholar Godfrey Baldacchino notes that as island narratives have moved “away from the perspective of the ‘explorer-discoverer-colonist’” they have been replaced by “the perspective of the ‘custodian-steward-environmentalist’” (49), but reminds readers that a colonising disposition still lurks beneath the surface. It must be remembered that terms such as “stewardship” and “leadership” can undertake sovereignty labour (Dodds “Awkward”), and that Tasmania’s Antarctic connections can be mobilised for a range of purposes. When Environment Minister Greg Hunt proclaimed at a press conference that: “Hobart is the gateway to the Antarctic for the future” (26 Apr. 2016), the remark had meaning within discourses of both sovereignty and economics. Tasmania’s capital was leveraged as a way to position Australia as a leader in the Antarctic arena.From ‘Gateway’ to ‘Antarctic City’While discussion of Antarctic ‘Gateway’ Cities often focuses on the economic and logistical benefit of their Antarctic connections, Hobart’s “gateway” identity, like those of its counterparts, stretches well beyond this, encompassing geological, climatic, historical, political, cultural and scientific links. Even the southerly wind, according to cartoonist Jon Kudelka, “has penguins in it” (Image 3). Hobart residents feel a high level of connection to Antarctica. In 2018, a survey of 300 randomly selected residents of Greater Hobart was conducted under the umbrella of the “Antarctic Cities” Australian Research Council Linkage Project led by Assoc. Prof. Juan Francisco Salazar (and involving all three present authors). Fourteen percent of respondents reported having been involved in an economic activity related to Antarctica, and 36% had attended a cultural event about Antarctica. Connections between the southern continent and Hobart were recognised as important: 71.9% agreed that “people in my city can influence the cultural meanings that shape our relationship to Antarctica”, while 90% agreed or strongly agreed that Hobart should play a significant role as a custodian of Antarctica’s future, and 88.4% agreed or strongly agreed that: “How we treat Antarctica is a test of our approach to ecological sustainability.” Image 3: “The Southerly” Demonstrates How Weather Connects Hobart and Antarctica. Image Credit: Jon Kudelka, Reproduced with Permission.Hobart, like the other gateways, activates these connections in its conscious place-branding. The city is particularly strong as a centre of Antarctic research: signs at the cruise-ship terminal on the waterfront claim that “There are more Antarctic scientists based in Hobart […] than at any other one place on earth, making Hobart a globally significant contributor to our understanding of Antarctica and the Southern Ocean.” Researchers are based at the Institute for Marine and Antarctic Studies (IMAS), the Commonwealth Scientific and Industrial Research Organisation (CSIRO), and the Australian Antarctic Division (AAD), with several working between institutions. Many Antarctic researchers located elsewhere in the world also have a connection with the place through affiliations and collaborations, leading journalist Jo Chandler to assert that “the breadth and depth of Hobart’s knowledge of ice, water, and the life forms they nurture […] is arguably unrivalled anywhere in the world” (86).Hobart also plays a significant role in Antarctica’s governance, as the site of the secretariats for the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR) and the Agreement on the Conservation of Albatrosses and Petrels (ACAP), and as host of the Antarctic Consultative Treaty Meetings on more than one occasion (1986, 2012). The cultural domain is active, with Tasmanian Museum and Art Gallery (TMAG) featuring a permanent exhibit, “Islands to Ice”, emphasising the ocean as connecting the two places; the Mawson’s Huts Replica Museum aiming (among other things) to “highlight Hobart as the gateway to the Antarctic continent for the Asia Pacific region”; and a biennial Australian Antarctic Festival drawing over twenty thousand visitors, about a sixth of them from interstate or overseas (Hingley). Antarctic links are evident in the city’s natural and built environment: the dolerite columns of Mt Wellington, the statue of the Tasmanian Antarctic explorer Louis Bernacchi on the waterfront, and the wharfs that regularly accommodate icebreakers such as the Aurora Australis and the Astrolabe. Antarctica is figured as a southern neighbour; as historian Tom Griffiths puts it, Tasmanians “grow up with Antarctica breathing down their necks” (5). As an Antarctic City, Hobart mediates access to Antarctica both physically and in the cultural imaginary.Perhaps in recognition of the diverse ways in which a region or a city might be connected to Antarctica, researchers have recently been suggesting critical approaches to the ‘gateway’ label. C. Michael Hall points to a fuzziness in the way the term is applied, noting that it has drifted from its initial definition (drawn from economic geography) as denoting an access and supply point to a hinterland that produces a certain level of economic benefits. While Hall looks to keep the term robustly defined to avoid empty “local boosterism” (272–73), Gabriela Roldan aims to move the concept “beyond its function as an entry and exit door”, arguing that, among other things, the local community should be actively engaged in the Antarctic region (57). Leane, examining the representation of Hobart as a gateway in historical travel texts, concurs that “ingress and egress” are insufficient descriptors of Tasmania’s relationship with Antarctica, suggesting that at least discursively the island is positioned as “part of an Antarctic rim, itself sharing qualities of the polar region” (45). The ARC Linkage Project described above, supported by the Hobart City Council, the State Government and the University of Tasmania, as well as other national and international partners, aims to foster the idea of the Hobart and its counterparts as ‘Antarctic cities’ whose citizens act as custodians for the South Polar region, with a genuine concern for and investment in its future.Near and Far: Local Perspectives A changing climate may once again herald a shift in the identity of the Tasmanian islands. Recognition of the central role of Antarctica in regulating the global climate has generated scientific and political re-evaluation of the region. Antarctica is not only the planet’s largest heat sink but is the engine of global water currents and wind patterns that drive weather patterns and biodiversity across the world (Convey et al. 543). For example, Tas van Ommen’s research into Antarctic glaciology shows the tangible connection between increased snowfall in coastal East Antarctica and patterns of drought southwest Western Australia (van Ommen and Morgan). Hobart has become a global centre of marine and Antarctic science, bringing investment and development to the city. As the global climate heats up, Tasmania—thanks to its low latitude and southerly weather patterns—is one of the few regions in Australia likely to remain temperate. This is already leading to migration from the mainland that is impacting house prices and rental availability (Johnston; Landers 1). The region’s future is therefore closely entangled with its proximity to the far south. Salazar writes that “we cannot continue to think of Antarctica as the end of the Earth” (67). Shifting Antarctica into focus also brings Tasmania in from the margins. As an Antarctic city, Hobart assumes a privileged positioned on the global stage. This allows the city to present itself as central to international research efforts—in contrast to domestic views of the place as a small regional capital. The city inhabits dual identities; it is both on the periphery of Australian concerns and at the centre of Antarctic activity. Tasmania, then, is not in freefall, but rather at the forefront of a push to recognise Antarctica as entangled with its neighbours to the north.AcknowledgementsThis work was supported by the Australian Research Council under LP160100210.ReferencesAntonello, Alessandro. “Finding Place in Antarctica.” Antarctica and the Humanities.

My thesis consists of three chapters. The first chapter uses the Factor-augmented Error Correction Model in model averaging for predictive regressions, which provides significant improvements with large datasets in areas where the individual methods have not. I allow the candidate models to vary by the number of dependent variable lags, the number of factors, and the number of cointegration ranks. I show that the leave-h-out cross-validation criterion is an asymptotically unbiased estimator of the optimal mean squared forecast error, using either the estimated cointegration vectors or the nonstationary regressors. Empirical results demonstrate that including cointegration relationships significantly improves long-run forecasts of a standard set of macroeconomic variables. I also estimate simulation-based prediction intervals for six real and nominal macroeconomics variables. The results are consistent with the point estimates, which further support the usefulness of cointegration in long-run forecasts.

The major purpose of this thesis is to offer a detailed look at the development of two models used to assist in the detailed study of Australian two lane two way highways with particular reference to heavy vehicles. The first model governs the acceleration behaviour of vehicles on upgrades and downgrades. The second model controls overtaking manoeuvres on two lane two way highways where movement into the lane of oncoming traffic is required. Both models are implemented through a suite of transport simulation modelling software called Paramics.

Risk, and how one proceeds with uncertainty, are key indicators of behavior. In particular, in observing farmers, risk perception is found to influence the decision to innovate and adopt new crops (Ghadim et al., 2005). Farmers who are more risk-averse tend to be later adopters of new crops, while risk-loving farmers tend to be first adopters (Barham et al., 2014). As such, the recent legal shifts in hemp production laws have prompted many growers eager to test out the crop to do so. A vast majority of current licensees planted less than 50 acres to start, despite being mostly corn and soy producers—implying large acreage access. The American ‘hemp rush’ provides us with a real-time display of adoption behavior and its gendered implications.

Second Essay: We estimate the cost of transporting corn and the resulting degree of spatial differentiation among downstream firms that buy corn from upstream farmers and examine whether such differentiation softens competition enabling buyers to exert market power (defined as the ability to pay a price for corn that is below its marginal value product net of processing cost). We estimate a structural model of spatial competition using corn procurement data from the US state of Indiana from 2004 to 2014. We adopt a strategy that allows us to estimate firm-level structural parameters while using aggregate data. Our results return a transportation cost of 0.12 cents per bushel per mile (3% of the corn price under average conditions), which provides evidence of spatial differentiation among buyers. The estimated average markdown is $0.80 per bushel (16% of the average corn price in the sample), of which $0.34 is explained by spatial differentiation and the rest by the fact that firms operated under binding capacity constraints. We also find that corn prices paid to farmers at the mill gate are independent of distance between the plant and the farm, providing evidence that firms do not engage in spatial price discrimination. Finally, we evaluate the effect of hypothetical mergers on input markets and farm surplus. A merger between nearby ethanol producers eases competition, increases markdowns by 20%, and triggers a sizable reduction in farm surplus. In contrast, a merger between distant buyers has little effect on competition and markdowns.

Third Essay: We study the dynamic response of local corn prices to entry of ethanol plants. We use spatially explicit panel data on elevator-level corn prices and ethanol plant entry and capacity to estimate an autoregressive distributed lag model with instrumental variables. We find that the average-sized entrant has no impact on local corn prices the year of entry. However, the price subsequently rises and stabilizes after two years at a level that is about 10 cents per bushel higher than the pre-entry level. This price effect dissipates as the distance between elevators and plants increase. Our results imply that long-run (2 years) supply elasticity is smaller than short-run (year of entry) supply elasticity. This may be due to rotation benefits that induce farmers to revert back to soybeans, after switching to corn due to price signals the year the plant enters. Furthermore, our results, in combination with findings in essay 2 of this dissertation, indicate that ethanol plants are likely to use pricing strategies consistent with a static rather than dynamic oligopsony competition.

Contemporary research indicates that the era of autonomous vehicles (AVs) is not only inevitable but may be reached sooner than expected; however, not enough research has been done to address road infrastructure readiness for supporting AV operations. Highway agencies at all levels of governments seek to identify the needed infrastructure changes to facilitate the successful integration of AVs into the existing roadway system. Given multiple sources of uncertainty particularly the market penetration of AVs, agencies find it difficult to justify the substantial investments needed to make these infrastructure changes using traditional value engineering approaches. It is needed to account for these uncertainties by doing a phased retrofitting of road infrastructure to keep up with the AV market penetration. This way, the agency can expand, defer, or scale back the investments at a future time. This dissertation develops a real options analysis (ROA) framework to address these issues while capturing the monetary value of investment timing flexibility. Using key stakeholder feedback, an extensive literature review, and discussions with experts, the needed AV-motivated changes in road infrastructure were identified across two stages of AV operations; the transition phase and the fully-autonomous phase. For a project-level case study of a 66-mile stretch of Indiana’s four-six lane Interstate corridor, two potential scenarios of infrastructure retrofitting were established and evaluated using the net present value (NPV) and ROA approaches. The results show that the NPV approach can lead to decisions at the start of the evaluation period but does not address the uncertainty associated with AV market penetration. In contrast, ROA was found to address uncertainty by incorporating investment timing flexibility and capturing its monetary value. Using the dissertation’s framework, agencies can identify and analyze a wide range of possible scenarios of AV-oriented infrastructure retrofitting to enhance readiness, at both the project and network levels.
