Liquid Corporeality, Femininity, and Fluid Time in V. H. Leslie's Bodies of Water

The analysis of multitemporal very high spatial resolution imagery is too often limited to the sole use of pixel digital numbers which do not accurately describe the observed targets between the various collections due to the effects of changing illumination, viewing geometries, and atmospheric conditions. This paper demonstrates both qualitatively and quantitatively that not only physically based quantities are necessary to consistently and efficiently analyze these data sets but also the angular information of the acquisitions should not be neglected as it can provide unique features on the scenes being analyzed. The data set used is composed of 21 images acquired between 2002 and 2009 by QuickBird over the city of Denver, Colorado. The images were collected near the downtown area and include single family houses, skyscrapers, apartment complexes, industrial buildings, roads/highways, urban parks, and bodies of water. Experiments show that atmospheric and geometric properties of the acquisitions substantially affect the pixel values and, more specifically, that the raw counts are significantly correlated to the atmospheric visibility. Results of a 22-class urban land cover experiment show that an improvement of 0.374 in terms of Kappa coefficient can be achieved over the base case of raw pixels when surface reflectance values are combined to the angular decomposition of the time series.

Chapter 5 - Application of constructed wetland; a natural treatment system for environmentally sustainable domestic sewage treatment

BackgroundAlthough larviciding may be a valuable tool to supplement long-lasting insecticide nets (LLINs) in West Africa in different ecological settings, its actual impact on malaria burden and transmission has yet to be demonstrated. A randomized controlled trial was therefore undertaken to assess the effectiveness of larviciding using Bacillus thuringiensis israeliensis (Bti) in addition to the use of LLINs. In order to optimally implement such a larviciding intervention, we first aimed to identify and to characterize the breeding habitats of Anopheles spp. in the entire study area located in the vicinity of Korhogo in northern Côte d’Ivoire.MethodsWe conducted two surveys during the rainy and the dry season, respectively, in the thirty villages around Korhogo involved in the study. In each survey, water bodies located within a 2 km radius around each village were identified and assessed for the presence of mosquito larvae. We morphologically identified the larvae to the genus level and we characterized all of the habitats positive for Anopheles spp. larvae based on a predefined set of criteria.ResultsOverall, 620 and 188 water bodies positive for Anopheles spp. larvae were sampled in the rainy and the dry season, respectively. A broad range of habitat types were identified. Rice paddies accounted for 61% and 57% of the habitats encountered in the rainy and the dry season, respectively. In the rainy season, edges of rivers and streams (12%) were the second most abundant habitats for Anopheles spp. larvae. More than 90% of the Anopheles spp. breeding habitats were surrounded by green areas. Dams, ponds and drains produced higher numbers of Anopheles spp. larvae per square meter than rice paddies (RR = 1.51; 95% CI: 1.18–1.94; P = 0.0010). The density of Anopheles spp. larvae was significantly higher in habitats surrounded by low-density housing (RR = 4.81; 95% CI: 1.84–12.60; P = 0.0014) and green areas (RR = 3.96; 95% CI: 1.92–8.16; P = 0.0002] than habitats surrounded by high-density housing. Turbid water [RR = 1.42 (95% CI: 1.15–1.76; P = 0.0012) was associated with higher densities of Anopheles spp. larvae. The likelihood of finding mosquito pupae in Anopheles spp. breeding habitats was higher in the dry season (OR = 5.92; 95% CI: 2.11–16.63; P = 0.0007) than in the rainy season.ConclusionsRice paddies represented the most frequent habitat type for Anopheles spp. larvae in the Korhogo area during both the rainy and the dry seasons. Anopheles spp. breeding habitats covered a very large and dynamic area in the rainy season whereas they were fewer in number in the dry season. In this context, implementing a larviciding strategy from the end of the rainy season to the dry season is presumably the most cost-effective strategy.

Decentralized wastewater treatment and reuse (DWTRU) using small-scale on-site sewage treatment plants (STPs) is an attractive solution addressing the problems of water pollution and scarcity, especially in rapidly urbanizing cities in developing countries, where centralized infrastructure for wastewater treatment is inadequate. But decentralized systems face several challenges (economic feasibility, public acceptance) that need to be better understood. The city of Bengaluru in India provides an excellent opportunity to evaluate such systems. In 2004, in an effort to curb the alarming levels of pollution in its water bodies due to untreated sewage disposal, the environmental regulatory agency mandated apartment complexes above a certain size to install STPs and reuse 100% of their wastewater, resulting in the installation of more than 2200 on-site STPs till date. This study attempts to analyze the factors influencing the extent of treatment and reuse in such systems, through structured surveys of residential associations, STP experts and government officials. The results are analyzed using a framework that integrates the technology adoption literature with the monitoring and enforcement literature. The study indicates that, while no apartment complex is able to reuse 100% of its treated water, there exists significant variation across apartment complexes in the level of treatment and reuse (from partial to poor) due to a complex mix of economies of scale, the price of fresh water, the level of enforcement and awareness, and technological choices made under information asymmetry. Only apartments dependent on expensive tanker water supply had clear economic incentives to comply with the order. Yet many large complexes that depended on low-priced utility or borewell supply were partially compliant, owing partly to lower (although positive) costs, higher level of formal enforcement and perhaps greater environmental awareness. On the other hand, the high treatment cost pushed smaller complexes to curtail the operation of their STPs (and the lower levels of enforcement further worsened this), resulting in inadequate treated water quality and consequently low reuse levels. The study recommends relaxing the infeasible 100% reuse criterion, and raising the threshold size above which DWTRU should be mandated so as to reduce the cost burden and increase enforceability. Subsidies towards capital costs and enabling resale of treated water will enable wider adoption. DWTRU is an apparently attractive solution that however, requires judicious policy-making and implementation to succeed.

Background Study data for Edible Urbanism: restructuring urban green voids.

The hydrocarbon-bearing inclusions, formation water, and crude oil contain a wealth of information regarding the process of accumulation of oil and gas. Their research has been one of the hotspots in the field of oil and gas geology. Chemical analysis data was systematically employed for the first time to identify the properties of liquid fluids in the oil-bearing system of the Wuliyasitai southern sag in the Erlian Basin. A biased lacustrine algal input was shown by the stable carbon isotopes (δ13C) of whole hydrocarbons, and the morphological characteristics of n-alkanes, isoprenoids, steranes, and terpenes were examined by gas chromatography-mass spectrometry. The δ13C values were determined by the salinity of the sedimentary water body and input of land-sourced materials. The signatures of the n-alkanes' molar fraction arrangement suggest that water washing, crystallization, and wax precipitation are regular occurrences in oil samples. The salinity of formation water and the proportion of characteristic biomarkers (gammacerane, β-carotene) demonstrate that the salinity of the ancient water body ranges from fresh water to brackish water. The correlation between the stratigraphic water's characteristic coefficients and the total dissolved solids (TDS) is strong, particularly for the desulfurization coefficient, which illustrates a better hydrocarbon storage environment when TDS is >6 g/L. The metamorphic coefficients demonstrate that the existing reservoir preservation circumstances are not optimal, and the TDS and concentration degree of formation water are positively connected to the increasing depth, indicating poor longitudinal connectivity. The influence of atmospheric water infiltration is responsible for the fluid inclusions' temperatures of homogenization (60 °C). However, due to deep burial, crude oil has not undergone secondary significant biodegradation despite the percolation of atmospheric water. Besides, the distribution of reservoirs is highly correlated with formation water parameters such as the TDS, which can provide scientific guidance for further exploration of oil and gas in the study area or even in the Erlian Basin.

The increasing population along with water scarcity give rise to water management practices. Water scarcity can be eradicated by wastewater treatment that would in turn prevent contamination of water bodies. One of the challenges in wastewater treatment is to efficiently transport and treat the sewage in a Sewage Treatment Plant (STP). Most of the existing STPs in closed campuses of Indian scenarios such as academic institutions, industries, and residential apartments employ several pumping stations in a campus and pump motors in each station that pump sewage to STP for treatment. Manual operation of such motors would lead to sump overflows that negatively impact public health and sanitation. Therefore, an IoT-based system for monitoring and controlling sewage flow is proposed in this paper that uses water level sensors and prevents sewage overflows in pumping station sumps, resulting in the utilisation of all the collected sewage for treatment. Since each campus might have different communication networks such as GPRS, WiFi, RF, or Ethernet, the proposed system is designed to work with any network. The proposed system was tested in the college campus with three pumping stations. Moreover, a test bed was simulated and tested with 100 pumping stations. It is observed that the proposed approach prevents sewage overflows in various scenarios with different constraints.

IntroductionThe walking tour is an enduring feature of cities. Fuelled by a desire to learn more about the hidden and unknown spaces of the city, the walking tour has moved beyond its historical role as tourist attraction to play a key role in the transformation of urban space through gentrification. Conversely, the walking tour has a counter-history as part of a critical urban praxis. This article reflects on historical examples, as well as our own experience of conducting Field Trip, a critical geographical walking tour through an industrial precinct in Marrickville, a suburb of Sydney that is set to undergo rapid change as a result of high-rise residential apartment construction (Gibson et al.). This precinct, known as Carrington Road, is located on the unceded land of the Cadigal and Wangal people of the Eora nation who call the area Bulanaming.Drawing on a long history of philosophical walking, many contemporary writers (Solnit; Gros; Bendiner-Viani) have described walking as a practice that can open different ways of thinking, observing and being in the world. Some have focused on the value of walking to the study of place (Hall; Philips; Heddon), and have underscored its relationship to established research methods, such as sensory ethnography (Springgay and Truman). The work of Michel de Certeau pays particular attention to the relationship between walking and the city. In particular, the concepts of tactics and strategy have been applied in a variety of ways across cultural studies, cultural geography, and urban studies (Morris). In line with de Certeau’s thinking, we view walking as an example of a tactic – a routine and often unconscious practice that can become a form of creative resistance.In this sense, walking can be a way to engage in and design the city by opposing its structures, or strategies. For example, walking in a city such as Sydney that is designed for cars requires choosing alternative paths, redirecting flows of people and traffic, and creating custom shortcuts. Choosing pedestrianism in Sydney can certainly feel like a form of resistance, and we make the argument that Field Trip – and walking tours more generally – can be a way of doing this collectively, firstly by moving in opposite directions, and secondly, at incongruent speeds to those for whom the scale and style of strategic urban development is inevitable. How such tactical walking relates to the design of cities, however, is less clear. Walking is a generally described in the literature as an individual act, while the design of cities is, at its best participatory, and always involving multiple stakeholders. This reveals a tension between the practice of walking as a détournement or appropriation of urban space, and its relationship to existing built form. Field Trip, as an example of collective walking, is one such appropriation of urban space – one designed to lead to more democratic decision making around the planning and design of cities. Given the anti-democratic, “post-political” nature of contemporary “consultation” processes, this is a seemingly huge task (Legacy et al.; Ruming). We make the argument that Field Trip – and walking tours more generally – can be a form of collective resistance to top-down urban planning.By using an open-source wiki in combination with the Internet Archive, Field Trip also seeks to collectively document and make public the local knowledge generated by walking at the frontier of gentrification. We discuss these digital choices as oppositional practice, and consider the idea of tactical media (Lovink and Garcia; Raley) in order to connect knowledge sharing with the practice of walking.This article is structured in four parts. Firstly, we provide a historical introduction to the relationship between walking tours and gentrification of global cities. Secondly, we examine the significance of walking tours in Sydney and then specifically within Marrickville. Thirdly, we discuss the Field Trip project as a citizen-led walking tour and, finally, elaborate on its role as tactical media project and offer some conclusions.The Walking Tour and Gentrification From the outset, people have been walking the city in their own ways and creating their own systems of navigation, often in spite of the plans of officialdom. The rapid expansion of cities following the Industrial Revolution led to the emergence of “imaginative geographies”, where mediated representations of different urban conditions became a stand-in for lived experience (Steinbrink 219). The urban walking tour as mediated political tactic was utilised as far back as Victorian England, for reasons including the celebration of public works like the sewer system (Garrett), and the “othering” of the working class through upper- and middle-class “slum tourism” in London’s East End (Steinbrink 220). The influence of the Situationist theory of dérive has been immense upon those interested in walking the city, and we borrow from the dérive a desire to report on the under-reported spaces of the city, and to articulate alternative voices within the city in this project. It should be noted, however, that as Field Trip was developed for general public participation, and was organised with institutional support, some aspects of the dérive – particularly its disregard for formal structure – were unable to be incorporated into the project. Our responsibility to the participants of Field Trip, moreover, required the imposition of structure and timetable upon the walk. However, our individual and collective preparation for Field Trip, as well as our collective understanding of the area to be examined, has been heavily informed by psychogeographic methods that focus on quotidian and informal urban practices (Crosby and Searle; Iveson et al).In post-war American cities, walking tours were utilised in the service of gentrification. Many tours were organised by real estate agents with the express purpose of selling devalorised inner-city real estate to urban “pioneers” for renovation, including in Boston’s South End (Tissot) and Brooklyn’s Park Slope, among others (Lees et al 25). These tours focused on a symbolic revalorisation of “slum neighbourhoods” through a focus on “high culture”, with architectural and design heritage featuring prominently. At the same time, urban socio-economic and cultural issues – poverty, homelessness, income disparity, displacement – were downplayed or overlooked. These tours contributed to a climate in which property speculation and displacement through gentrification practices were normalised. To this day, “ghetto tours” operate in minority neighbourhoods in Brooklyn, serving as a beachhead for gentrification.Elsewhere in the world, walking tours are often voyeuristic, featuring “locals” guiding well-meaning tourists through the neighbourhoods of some of the world’s most impoverished communities. Examples include the long runningKlong Toei Private Tour, through “Bangkok’s oldest and largest slum”, or the now-ceased Jakarta Hidden Tours, which took tourists to the riverbanks of Jakarta to see the city’s poorest before they were displaced by gentrification.More recently, all over the world activists have engaged in walking tours to provide their own perspective on urban change, attempting to direct the gentrifier’s gaze inward. Whilst the most confrontational of these might be the Yuppie Gazing Tour of Vancouver’s historically marginalised Downtown Eastside, other tours have highlighted the deleterious effects of gentrification in Williamsburg, San Francisco, Oakland, and Surabaya, among others. In smaller towns, walking tours have been utilised to highlight the erasure of marginalised scenes and subcultures, including underground creative spaces, migrant enclaves, alternative and queer spaces. Walking Sydney, Walking Marrickville In many cities, there are now both walking tours that intend to scaffold urban renewal, and those that resist gentrification with alternative narratives. There are also some that unwittingly do both simultaneously. Marrickville is a historically working-class and migrant suburb with sizeable populations of Greek and Vietnamese migrants (Graham and Connell), as well as a strong history of manufacturing (Castles et al.), which has been undergoing gentrification for some time, with the arts playing an often contradictory role in its transformation (Gibson and Homan). More recently, as the suburb experiences rampant, financialised property development driven by global flows of capital, property developers have organised their own self-guided walking tours, deployed to facilitate the familiarisation of potential purchasers of dwellings with local amenities and ‘character’ in precincts where redevelopment is set to occur. Mirvac, Marrickville’s most active developer, has designed its own self-guided walking tour Hit the Marrickville Pavement to “explore what’s on offer” and “chat to locals”: just 7km from the CBD, Marrickville is fast becoming one of Sydney’s most iconic suburbs – a melting pot of cuisines, creative arts and characters founded on a rich multicultural heritage.The perfect introduction, this self-guided walking tour explores Marrickville’s historical architecture at a leisurely pace, finishing up at the pub.So, strap on your walking shoes; you're in for a treat.Other walking tours in the area seek to highlight political, ecological, and architectural dimension of Marrickville. For example, Marrickville Maps: Tropical Imaginaries of Abundance provides a series of plant-led walks in the suburb; The Warren Walk is a tour organised by local Australian Labor Party MP Anthony Albanese highlighting “the influence of early settlers such as the Schwebel family on the area’s history” whilst presenting a “political snapshot” of ALP history in the area. The Australian Ugliness, in contrast, was a walking tour organised by Thomas Lee in 2016 that offered an insight into the relationships between the

Reviewed by: Exquisite Materials: Episodes in the Queer History of Victorian Style by Abigail Joseph Alison Matthews David (bio) Exquisite Materials: Episodes in the Queer History of Victorian Style, by Abigail Joseph; pp. xiii + 308. Newark: University of Delaware Press, 2019, $79.50, $39.50 paper. The first chapter of Abigail Joseph's book, "Dress and Drag Around 1870," conjured up a vivid personal encounter with Victorian fashion. The queer readings of high Victorian style for which Joseph convincingly argues help me retroactively to understand the 1873 fashion plate that sat, framed, on our bathroom counter during my early childhood a century later. On this plate, women and girls promenaded in a park dressed in attire that my equally flamboyantly clad orange-polyester-shirted and plaid-bellbottom-trousered self found both bizarre and enticing. This 1970s self would have looked boyish in the extreme by the standards of Victorian girlhood. Who were these doll-like people, dressed in layer after extravagant layer of blue and white fabric, ribbons, flounces and lace, with odd hats perched on their heads? Joseph singles out the 1870s as a decade known for its excessive ornamentation. It was also a decade known for the performative quality that it imparted to the wardrobes of both fashionable women and cross-dressers, like Ernest (Stella) Boulton and Frederick (Fanny) Park. As the owner of a magical childhood dress-up box, it is no wonder that I was entranced by the styles worn in a decade when fashion took on the quality of "costumes … for a 'fancydress ball,' a masquerade, outfits intended to transfigure their wearer into someone she (or he) is not, to serve as the visual and material apparatus enabling a material role to be played, the boundaries of identities to be blurred" (33). Exquisite Materials: Episodes in the Queer History of Victorian Style does an excellent job of situating and queering some of the most exaggeratedly extreme decades in Victorian feminine style and silhouettes. Joseph's framework provides a welcome and sympathetic lens through which scholars across a range of disciplines can re-view queer affective networks and archives through things, with a focus on dress and ephemera in particular. This lens is welcome in the context of a pandemic-influenced style landscape that provoked a renewed interest in nonbinary forms of dress and expression. Through her nuanced exploration of the many lacunae and silences in the queer archives, as well as by reading the sometimes surprising presences, Joseph's book speaks to the sensual and [End Page 163] sensory importance of small objects, from pets to letters, as they circulated in queer networks, having profound impacts on the lives and experiences of all those who came into contact with them. As dress and gender have always been linked in the most visible and tangible ways, it is particularly pertinent to view the mid- and high Victorian periods, often seen as two of the most binary and polarized periods in fashion, through multiple queer and trans lenses. Though this was a period when young boys wore dresses until they were breeched, the author argues, it was also a historical moment when questions of sexuality were being reformulated. Dress was literally policed by the imposition of dress laws in many places worldwide, a process intimately linked with racism and colonization, as Clare Sears powerfully demonstrates in their groundbreaking book Arresting Dress: Cross-Dressing, Law, and Fascination in Nineteenth-Century San Francisco (2014). My own field, fashion studies, has produced a wide range of texts, classic and contemporary, that focus on the ways in which dress has played with the gender binary. From Peter McNeil's Pretty Gentlemen: Macaroni Men and the Eighteenth-Century Fashion World (2018) to Ben Barry and Andrew Reilly's edited volume Crossing Gender Boundaries: Fashion to Create, Disrupt and Transcend (2020), which examines male Victorian corset or belt wearing and early bifurcated skirts for women, scholars continue to be interested in how dress embodies and displays gender nonconformity. Exquisite Materials divides its subject matter into four chapters. Three focus on case studies where style, either literary or sartorial, was actually criminalized in a legal context because of its associations with queer sexualities. These...
