Academic literature on the topic 'Shallowly embedded connections'

Anchor channels are cast in concrete and allow the connection of components using channel bolts. In recent years, the design to value resulted in ever thinner concrete elements, which often cannot accommodate the required embedment depth of standard anchor channels. For this reason, channels may be fitted with short anchors. While existing design provisions allow for the calculation of the tension capacity also for shallow embedded anchor channels, tests are required to determine product-specific parameters for the economic shear loads design. The presented study investigated the performance of shallow embedded anchor channels tested in shear. The detailed evaluation of the test data demonstrates that testing of the minimum embedment is conservative and that the load-displacement behavior of channels with welded I-sections is comparable to that of channels with forged headed studs. In addition, a new evaluation approach is proposed.

Bridge crack detection is essential to prevent transportation accidents. However, the surrounding environment has great interference with the detection of cracks, which makes it difficult to ensure the accuracy of the detection. In order to accurately detect bridge cracks, we proposed an end-to-end model named Skip-Squeeze-and-Excitation Networks (SSENets). It is mainly composed of the Skip-Squeeze-Excitation (SSE) module and the Atrous Spatial Pyramid Pooling (ASPP) module. The SSE module uses skip-connection strategy to enhance the gradient correlation between the shallow network and deeper network, alleviating the vanishing gradient caused by the deepening of the network. The ASPP module can extract multi-scale contextual information of images, while the depthwise separable convolution reduces computational complexity. In order to avoid destroying the topology of crack, we used atrous convolution instead of the pooling layer. The proposed SSENets achieved a detection accuracy of 97.77%, which performed better than the models we compared it with. The designed SSE module which used skip-connection strategy can be embedded in other convolutional neural networks (CNNs) to improve their performance.

Abstract. East of Madagascar, the shallow “South Indian Ocean Counter Current (SICC)” flows from west to east across the Indian Ocean against the direction of the wind-driven circulation. The SICC impinges on west Australia and enhances the sea level slope, strengthening the alongshore coastal jet: the Leeuwin Current (LC), which flows poleward along Australia. An observed transport maximum of the LC around 22° S can likely be attributed to this impingement of the SICC. The LC is often described as a regional coastal current that is forced by an offshore meridional density gradient or sea surface slope. However, little is known about the controls of these open-ocean gradients. The regional circulation system is embedded in the subtropical “super gyre” that connects the Indo-Pacific via the Tasman Gateway and the Indonesian passages. The Indonesian Throughflow (ITF) circulates through the Indian Ocean back into the Pacific south of Australia. This return pathway appears to be partly trapped in the upper layer north of an outcrop line. It is redirected along this outcrop line and joins the eastward flow of the SICC. To study the connection of the basin-scale and the inter-ocean-scale dynamics, we apply both an ocean general circulation model and a conceptual two-layer model. Shutdown of the ITF in the models leads to a large decrease in Leeuwin Current transport. Most of the SICC was found to then reconnect to the internal gyre circulation in the Indian Ocean. ITF, SICC and LC thus appear to be dynamically connected.

Abstract Strong southerly, terrain parallel winds often occur along the coast of north-central Chile (25°–35°S) embedded in the marine atmospheric boundary layer and the lower part of the capping temperature inversion. Their offshore structure and variability have received considerable attention because of the effect on open-ocean processes and connection with the southeast Pacific cloud layer. Mesoscale low-level circulations linked to the coastal topography (e.g., coastal jets and sea breeze) are less studied in Chile, but are particularly relevant as they alter the upper-ocean circulation and the cloud pattern in the nearshore strip. Surface, radiosonde, and airborne meteorological observations near point Lengua de Vaca (LdV)–Tongoy Bay (TB) at 30°S are used alongside numerical modeling to understand the local circulation near a prominent upwelling center. Most observations were gathered during the Variability of the American Monsoon Systems (VAMOS) Ocean–Cloud–Atmosphere–Land Study Chilean Upwelling Experiment (VOCALS-CUpEx) during two weeks in late spring 2009. The regional topography resembles other major capes, but south of TB and east of LdV there is a low (100–300 m), dry marine terrace bounded by high elevation at the coast (~600 m) and farther inland. Coastal soundings 25 km upstream of LdV revealed a southerly wind maximum near the surface and another at 900 m separated by a destabilized layer, deviating from the two-layer model often applied to coastal flow. In the morning a shallow sea breeze penetrates from TB to the marine terrace, but is overridden by southerly flow in the afternoon. Furthermore, between 400 and 900 m, warm continental air is advected from over the marine terrace creating a residual boundary layer over TB. Concurrent with slower changes offshore, the low-level warming over TB leads to a marked cross-shore pressure gradient enhancing the coastal jet just north of LdV.

Resurfacing hip and knee endoprostheses are generally embedded in shallow, prepared areas in the bone and secured with cement. Massive cement penetration into periarticular bone, although it provides sufficient primary fixation, leads to the progressive weakening of peri-implant bone and results in failures. The aim of this paper was to investigate in an animal model the first biomimetic fixation of components of resurfacing arthroplasty endoprostheses by means of the innovative multispiked connecting scaffold (MSC-Scaffold). The partial resurfacing knee arthroplasty (RKA) endoprosthesis working prototype with the MSC-Scaffold was designed for biomimetic fixation investigations using reverse engineering methods and manufactured by selective laser melting. After Ca-P surface modification of bone contacting surfaces of the MSC-Scaffold, the working prototypes were implanted in 10 swines. Radiological, histopathological, and micro-CT examinations were performed on retrieved bone-implant specimens. Clinical examination confirmed very good stability (4 in 5-point Likert scale) of the operated knee joints. Radiological examinations showed good implant fixation (radiolucency less than 2 mm) without any signs of migration. Spaces between the MSC-Scaffold spikes were penetrated by bone tissue. The histological sections showed newly formed trabecular bone tissue between the spikes, and the trabeculae of periscaffold bone were seen in contact with the spikes. The micro-CT results showed the highest percentage of bone tissue ingrowths into the MSC-Scaffold at a distance of 2.5÷3.0 mm from the spikes bases. The first biomimetic fixation for resurfacing arthroplasty was successfully verified in 10 swines investigations using RKA endoprosthesis working prototypes. The performed research shows that the MSC-Scaffold allows for cementless and biomimetic fixation of resurfacing endoprosthesis components in periarticular cancellous bone.

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.

As the name suggests, the humanities is largely a study of the human condition, in which history sits as a discipline concerned with the past. Environmental history is a new field that brings together scholars from a range of disciplines to consider the changing relationships between humans and the environment over time. Critiques of anthropocentrism that place humans at the centre of the universe or make assessments through an exclusive human perspective provide a challenge to scholars to rethink our traditional biases against the nonhuman world. The movement towards nonhumanism or posthumanism, however, does not seem to have had much of an impression on history as a discipline. What would a nonhumanist history look like if we re-centred the historical narrative around pigs? There are histories of pigs as food (see for example, The Cambridge History of Food which has a chapter on “Hogs”). There are food histories that feature pork in terms of its relationship to multiethnic identity (such as Donna Gabaccia’s We Are What We Eat) and examples made of pigs to promote ethical eating (Singer). Pigs are central to arguments about dietary rules and what motivates them (Soler; Dolander). Ancient pig DNA has also been employed in studies on human migration and colonisation (Larson et al.; Durham University). Pigs are also widely used in a range of products that would surprise many of us. In 2008, Christien Meindertsma spent three years researching the products made from a single pig. Among some of the more unexpected results were: ammunition, medicine, photographic paper, heart valves, brakes, chewing gum, porcelain, cosmetics, cigarettes, hair conditioner and even bio diesel. Likewise, Fergus Henderson, who coined the term ‘nose to tail eating’, uses a pig on the front cover of the book of that name to suggest the extraordinary and numerous potential of pigs’ bodies. However, my intention here is not to pursue a discussion of how parts of their bodies are used, rather to consider a reorientation of the historical narrative to place pigs at the centre of stories of our co-evolution, in order to see what their history might say about humans and our relationships with them. This is underpinned by recognition of the inter-relationality of humans and animals. The relationships between wild boar and pigs with humans has been long and diverse. In a book exploring 10,000 years of interaction, Anton Ervynck and Peter Rowley-Conwy argue that pigs have been central to complex cultural developments in human societies and they played an important role in human migration patterns. The book is firmly grounded within the disciplines of zoology, anthropology and archaeology and contributes to an understanding of the complex and changing relationship humans have historically shared with wild boar and domestic pigs. Naturalist Lyall Watson also explores human/pig relationships in The Whole Hog. The insights these approaches offer for the discipline of history are valuable (although overlooked) but, more importantly, such scholarship also challenges a humanist perspective that credits humans exclusively with historical change and suggests, moreover, that we did it alone. Pigs occupy a special place in this history because of their likeness to humans, revealed in their use in transplant technology, as well as because of the iconic and paradoxical status they occupy in our lives. As Ervynck and Rowley-Conwy explain, “On the one hand, they are praised for their fecundity, their intelligence, and their ability to eat almost anything, but on the other hand, they are unfairly derided for their apparent slovenliness, unclean ways, and gluttonous behaviour” (1). Scientist Niamh O’Connell was struck by the human parallels in the complex social structures which rule the lives of pigs and people when she began a research project on pig behaviour at the Agricultural Research Institute at Hillsborough in County Down (Cassidy). According to O’Connell, pigs adopt different philosophies and lifestyle strategies to get the most out of their life. “What is interesting from a human perspective is that low-ranking animals tend to adopt one of two strategies,” she says. “You have got the animals who accept their station in life and then you have got the other ones that are continually trying to climb, and as a consequence, their life is very stressed” (qtd. in Cassidy). The closeness of pigs to humans is the justification for their use in numerous experiments. In the so-called ‘pig test’, code named ‘Priscilla’, for instance, over 700 pigs dressed in military uniforms were used to study the effects of nuclear testing at the Nevada (USA) test site in the 1950s. In When Species Meet, Donna Haraway draws attention to the ambiguities and contradictions promoted by the divide between animals and humans, and between nature and culture. There is an ethical and critical dimension to this critique of human exceptionalism—the view that “humanity alone is not [connected to the] spatial and temporal web of interspecies dependencies” (11). There is also that danger that any examination of our interdependencies may just satisfy a humanist preoccupation with self-reflection and self-reproduction. Given that pigs cannot speak, will they just become the raw material to reproduce the world in human’s own image? As Haraway explains: “Productionism is about man the tool-maker and -user, whose highest technical production is himself […] Blinded by the sun, in thrall to the father, reproduced in the sacred image of the same, his rewards is that he is self-born, an auto telic copy. That is the mythos of enlightenment and transcendence” (67). Jared Diamond acknowledges the mutualistic relationship between pigs and humans in Guns, Germs and Steel and the complex co-evolutionary path between humans and domesticated animals but his account is human-centric. Human’s relationships with pigs helped to shape human history and power relations and they spread across the world with human expansion. But questioning their utility as food and their enslavement to this cause was not part of the account. Pigs have no voice in the histories we write of them and so they can appear as passive objects in their own pasts. Traces of their pasts are available in humanity’s use of them in, for example, the sties built for them and the cooking implements used to prepare meals from them. Relics include bones and viruses, DNA sequences and land use patterns. Historians are used to dealing with subjects that cannot speak back, but they have usually left ample evidence of what they have said. In the process of writing, historians attempt to perform the miracle, as Curthoys and Docker have suggested, of restoration; bringing the people and places that existed in the past back to life (7). Writing about pigs should also attempt to bring the animal to life, to understand not just their past but also our own culture. In putting forward the idea of an alternative history that starts with pigs, I am aware of both the limits to such a proposal, and that most people’s only contact with pigs is through the meat they buy at the supermarket. Calls for a ban on intensive pig farming (RSPCA, ABC, AACT) might indeed have shocked people who imagine their dinner comes from the type of family farm featured in the movie Babe. Baby pigs in factory farms would have been killed a long time before the film’s sheep dog show (usually at 3 to 4 months of age). In fact, because baby pigs do grow so fast, 48 different pigs were used to film the role of the central character in Babe. While Babe himself may not have been aware of the relationship pigs generally have to humans, the other animals were very cognisant of their function. People eat pigs, even if they change the name of the form it takes in order to do so:Cat: You know, I probably shouldn’t say this, but I’m not sure if you realize how much the other animals are laughing at you for this sheep dog business. Babe: Why would they do that? Cat: Well, they say that you’ve forgotten that you’re a pig. Isn't that silly? Babe: What do you mean? Cat: You know, why pigs are here. Babe: Why are any of us here? Cat: Well, the cow’s here to be milked, the dogs are here to help the Boss's husband with the sheep, and I’m here to be beautiful and affectionate to the boss. Babe: Yes? Cat: [sighs softly] The fact is that pigs don’t have a purpose, just like ducks don’t have a purpose. Babe: [confused] Uh, I—I don’t, uh ... Cat: Alright, for your own sake, I’ll be blunt. Why do the Bosses keep ducks? To eat them. So why do the Bosses keep a pig? The fact is that animals don’t seem to have a purpose really do have a purpose. The Bosses have to eat. It’s probably the most noble purpose of all, when you come to think about it. Babe: They eat pigs? Cat: Pork, they call it—or bacon. They only call them pigs when they’re alive (Noonan). Babe’s transformation into a working pig to round up the sheep makes him more useful. Ferdinand the duck tried to do the same thing by crowing but was replaced by an alarm clock. This is a common theme in children’s stories, recalling Charlotte’s campaign to praise Wilbur the pig in order to persuade the farmer to let him live in E. B. White’s much loved children’s novel, Charlotte’s Web. Wilbur is “some pig”, “terrific”, “radiant” and “humble”. In 1948, four years before Charlotte’s Web, White had published an essay “Death of a Pig”, in which he fails to save a sick pig that he had bought in order to fatten up and butcher. Babe tried to present an alternative reality from a pig’s perspective, but the little pig was only spared because he was more useful alive than dead. We could all ask the question why are any of us here, but humans do not have to contemplate being eaten to justify their existence. The reputation pigs have for being filthy animals encourages distaste. In another movie, Pulp Fiction, Vincent opts for flavour, but Jules’ denial of pig’s personalities condemns them to insignificance:Vincent: Want some bacon? Jules: No man, I don’t eat pork. Vincent: Are you Jewish? Jules: Nah, I ain’t Jewish, I just don’t dig on swine, that’s all. Vincent: Why not? Jules: Pigs are filthy animals. I don’t eat filthy animals. Vincent: Bacon tastes gooood. Pork chops taste gooood. Jules: Hey, sewer rat may taste like pumpkin pie, but I’d never know ’cause I wouldn’t eat the filthy motherfucker. Pigs sleep and root in shit. That’s a filthy animal. I ain’t eat nothin’ that ain’t got sense enough to disregard its own feces [sic]. Vincent: How about a dog? Dogs eats its own feces. Jules: I don’t eat dog either. Vincent: Yeah, but do you consider a dog to be a filthy animal? Jules: I wouldn’t go so far as to call a dog filthy but they’re definitely dirty. But, a dog’s got personality. Personality goes a long way. Vincent: Ah, so by that rationale, if a pig had a better personality, he would cease to be a filthy animal. Is that true? Jules: Well we’d have to be talkin’ about one charming motherfuckin’ pig. I mean he’d have to be ten times more charmin’ than that Arnold on Green Acres, you know what I’m sayin’? In the 1960s television show Green Acres, Arnold was an exceptional pig who was allowed to do whatever he wanted. He was talented enough to write his own name and play the piano and his attempts at painting earned him the nickname “Porky Picasso”. These talents reflected values that are appreciated, and so he was. The term “pig” is, however, chiefly used a term of abuse, however, embodying traits we abhor—gluttony, obstinence, squealing, foraging, rooting, wallowing. Making a pig of yourself is rarely honoured. Making a pig of the humanities, however, could be a different story. As a historian I love to forage, although I use white gloves rather than a snout. I have rubbed my face and body on tree trunks in the service of forestry history and when the temperature rises I also enjoy wallowing, rolling from side to side rather than drawing a conclusion. More than this, however, pigs provide a valid means of understanding key historical transitions that define modern society. Significant themes in modern history—production, religion, the body, science, power, the national state, colonialism, gender, consumption, migration, memory—can all be understood through a history of our relationships with pigs. Pigs play an important role in everyday life, but their relationship to the economic, social, political and cultural matters discussed in general history texts—industrialisation, the growth of nation states, colonialism, feminism and so on—are generally ignored. However “natural” this place of pigs may seem, culture and tradition profoundly shape their history and their own contribution to those forces has been largely absent in history. What, then, would the contours of such a history that considered the intermeshing of humans and pigs look like? The intermeshing of pigs in early human history Agricultural economies based on domestic animals began independently in different parts of the world, facilitating increases in population and migration. Evidence for long-term genetic continuity between modern and ancient Chinese domestic pigs has been established by DNA sequences. Larson et al. have made an argument for five additional independent domestications of indigenous wild boar populations: in India, South East Asia and Taiwan, which they use to develop a picture of both pig evolution and the development and spread of early farmers in the Far East. Domestication itself involves transformation into something useful to animals. In the process, humans became transformed. The importance of the Fertile Crescent in human history has been well established. The area is attributed as the site for a series of developments that have defined human history—urbanisation, writing, empires, and civilisation. Those developments have been supported by innovations in food production and animal husbandry. Pig, goats, sheep and cows were all domesticated very early in the Fertile Crescent and remain four of the world’s most important domesticated mammals (Diamond 141). Another study of ancient pig DNA has concluded that the earliest domesticated pigs in Europe, believed to be descended from European wild boar, were introduced from the Middle East. The research, by archaeologists at Durham University, sheds new light on the colonisation of Europe by early farmers, who brought their animals with them. Keith Dobney explains:Many archaeologists believe that farming spread through the diffusion of ideas and cultural exchange, not with the direct migration of people. However, the discovery and analysis of ancient Middle Eastern pig remains across Europe reveals that although cultural exchange did happen, Europe was definitely colonised by Middle Eastern farmers. A combination of rising population and possible climate change in the ‘fertile crescent’, which put pressure on land and resources, made them look for new places to settle, plant their crops and breed their animals and so they rapidly spread west into Europe (ctd in ScienceDaily). Middle Eastern farmers colonised Europe with pigs and in the process transformed human history. Identity as a porcine theme Religious restrictions on the consumption of pigs come from the same area. Such restrictions exist in Jewish dietary laws (Kashrut) and in Muslim dietary laws (Halal). The basis of dietary laws has been the subject of much scholarship (Soler). Economic and health and hygiene factors have been used to explain the development of dietary laws historically. The significance of dietary laws, however, and the importance attached to them can be related to other purposes in defining and expressing religious and cultural identity. Dietary laws and their observance may have been an important factor in sustaining Jewish identity despite the dispersal of Jews in foreign lands since biblical times. In those situations, where a person eats in the home of someone who does not keep kosher, the lack of knowledge about your host’s ingredients and the food preparation techniques make it very difficult to keep kosher. Dietary laws require a certain amount of discipline and self-control, and the ability to make distinctions between right and wrong, good and evil, pure and defiled, the sacred and the profane, in everyday life, thus elevating eating into a religious act. Alternatively, people who eat anything are often subject to moral judgments that may also lead to social stigmatisation and discrimination. One of the most powerful and persuasive discourses influencing current thinking about health and bodies is the construction of an ‘obesity epidemic’, critiqued by a range of authors (see for example, Wright & Harwood). As omnivores who appear indiscriminate when it comes to food, pigs provide an image of uncontrolled eating, made visible by the body as a “virtual confessor”, to use Elizabeth Grosz’s term. In Fat Pig, a production by the Sydney Theatre Company in 2006, women are reduced to being either fat pigs or shrieking shallow women. Fatuosity, a blog by PhD student Jackie Wykes drawing on her research on fat and sexual subjectivity, provides a review of the play to describe the misogyny involved: “It leaves no options for women—you can either be a lovely person but a fat pig who will end up alone; or you can be a shrill bitch but beautiful, and end up with an equally obnoxious and shallow male counterpart”. The elision of the divide between women and pigs enacted by such imagery also creates openings for new modes of analysis and new practices of intervention that further challenge humanist histories. Such interventions need to make visible other power relations embedded in assumptions about identity politics. Following the lead of feminists and postcolonial theorists who have challenged the binary oppositions central to western ideology and hierarchical power relations, critical animal theorists have also called into question the essentialist and dualist assumptions underpinning our views of animals (Best). A pig history of the humanities might restore the central role that pigs have played in human history and evolution, beyond their exploitation as food. Humans have constructed their story of the nature of pigs to suit themselves in terms that are specieist, racist, patriarchal and colonialist, and failed to grasp the connections between the oppression of humans and other animals. The past and the ways it is constructed through history reflect and shape contemporary conditions. In this sense, the past has a powerful impact on the present, and the way this is re-told, therefore, also needs to be situated, historicised and problematicised. The examination of history and society from the standpoint of (nonhuman) animals offers new insights on our relationships in the past, but it might also provide an alternative history that restores their agency and contributes to a different kind of future. As the editor of Critical Animals Studies, Steve Best describes it: “This approach, as I define it, considers the interaction between human and nonhuman animals—past, present, and future—and the need for profound changes in the way humans define themselves and relate to other sentient species and to the natural world as a whole.” References ABC. “Changes to Pig Farming Proposed.” ABC News Online 22 May 2010. 10 Aug. 2010 http://www.abc.net.au/news/stories/2010/05/22/2906519.htm Against Animal Cruelty Tasmania. “Australia’s Intensive Pig Industry: The Intensive Pig Industry in Australia Has Much to Hide.” 10 Sep. 2010 http://www.aact.org.au/pig_industry.htm Babe.

Finite element models were created in Abaqus 6.14 to characterize the rotational stiffness of shallowly embedded column-foundation connections. Scripts were programmed to automate the model generation process and allow study of multiple independent variables, including embedment length, column size, baseplate geometry, concrete modulus, column orientation, cantilever height, and applied axial load. Three different connection types were investigated: a tied or one part model; a contact-based model; and a cohesive-zone based model. Cohesive-zone modeling was found to give the most accurate results. Agreement with previous experimental data was obtained to within 27%. Baseplate geometry was found to affect connection stiffness significantly, especially at lower embedment depths. The connection rotational stiffness was found to vary only slightly with cantilever height for typical column heights. Results from varying other parameters are also discussed.

Shallowly embedded column base connections with unreinforced block out concrete are a common method of connecting steel columns to their foundation. There has been little research done to accurately quantify the effects of this block out concrete on the connection strength and rigidity, and therefore there is nothing to aid the practicing engineer in accounting for this in structural analysis. Due to this lack of understanding, engineers have typically ignored the effects of shallow block out concrete in their analysis, presumably leading to a conservative design. Recent research has attempted to fill this gap in understanding. Several methods have been proposed that seek to quantify the effects of shallow block out concrete on a column base connection. Barnwell proposed a model that predicts the strength of a connection. Both Jones and Tryon used numerical modeling to predict the rotational stiffness of the connection. An experimental study was carried out to investigate the validity of these proposed models. A total of 8 test specimens were created at 2/3 scale with varying column sizes, connection details, and embedment depths. The columns were loaded laterally and cyclically at increasing displacements until the connection failed. The results show that the strength model proposed by Barnwell is reasonable and appropriate, and when applied to this series of physical tests produce predictions that have an observed/predicted ratio of between 0.95 to 1.39. The results also show that methods for estimating the rotational stiffness of the connection at the top of the block out concrete, as proposed by Jones and Tryon also produce reasonable values that had observed/predicted ratios of between 0.93 to 1.47. An alternative model for determining a design value for the rotational stiffness of a shallowly embedded column base plate is also proposed. When the embedment depth to column depth ratio is greater than 1.22, the connection is sufficiently rigid and at small deflections (less than 1% story drift) may be accurately modelled with infinite rotational stiffness (a "fixed" connection) at the base of the column.

Shallow embedded steel column connections are widely used in steel buildings; however, there is insufficient research about this connection type to understand the actual rotational stiffness that the connection provides. Shallow embedded steel columns are when a steel column is anchored to the foundation slab and then unreinforced concrete is poured around the base plate and the base of the column. This thesis seeks to further quantify the rotational stiffness available in this type of connection due to the added concrete and improve an existing model in order to represent the rotational stiffness. Existing data from two series of experiments on shallow embedded columns were used to validate and improve an existing rotational stiffness model. These two data sets were reduced in the same manner so that they could be compared to one another. In addition, the rotational stiffness for each test column was determined so they could be evaluated against the outputs of the model. The existing model was improved by evaluating each parameter in the model: the modulus of subgrade reaction, exposed column length, modulus of concrete for the blockout and the foundation slab, flange effective width, embedment depth, and effective column depth. It was determined that the model was sensitive to the subgrade reaction, modulus of concrete, embedment depth and effective column depth. The exposed length was not a highly sensitive parameter to the model. Flange effective width was determined to not be needed, especially when the other parameters were altered.

Shallow embedded column connections are widely used for columns resisting gravity loads in current design methods. These connections are usually considered “pinned” for structural analysis. In reality these connections fall in between a fixed and a pinned condition. Although methods exist to estimate the stiffness and strength of exposed columns or embedded columns under lateral loads, little research has been done to determine the strength of shallow embedded columns. An experimental study was carried out to investigate the strength of these connections. A total of 12 specimens with varying orientation, embedment depth, and column size were loaded laterally until failure or significant loss in strength. The results showed that shallow embedded connections are 86%-144% stronger in yielding and 32%-64% stronger in ultimate strength than current design methods would predict. This strength comes from a combination of the embedment depth and the resistance from the base plate and anchor rods. A model is proposed to explain the strength of the specimens and to conservatively estimate the strength of specimens with different variables. The specimens also exhibited stiffness ranging from 50%-75% of what would be expected from fully embedded columns.
