Residential water conservation in Austin, Texas

Sires, Luke Abrams 18 August 2010 (has links)
This study explores the social, technological economic, and environmental development of single-family residential water conservation programs at the Austin Water Utility and asks: What makes a conservation program successful? I hypothesize that water conservation programs will be successful if both institutional-producer goals and citizen-consumer goals are satisfied. While the findings suggest that this may be partially true, it also has become clear that my original actor-network model was too simple to predict the various types of influences on program success. Not only did I find other significant ‘actors’ involved in water conservation, I also found that utility and participant groups themselves represent a wide variety of interests. This study seeks to answer the research question by creating a series of narratives that critically explore water infrastructure and water conservation programs in Austin, Texas. Through a methodological lens referred to as ‘critical constructivism,’ I use mixed methods to analyze and interpret historic documents, interviews, and quantitative data as primary sources. Literature from Science and Technology Studies (STS) are used as secondary sources. This study will add to a body of knowledge that describes how and why we manage our environmental resources. The subject of conservation is especially relevant as urban growth continues with fewer affordable opportunities to increase regional water supplies. As we enter an era of expected water conflict, knowing how to conserve water effectively will help provide more opportunities for sharing a common resource amongst communities, industry, agriculture, and the environment. / text

Wie kommt die Robotik zum Sozialen? Epistemische Praktiken der Sozialrobotik.

Bischof, Andreas 01 March 2017 (has links) (PDF)
In zahlreichen Forschungsprojekten wird unter Einsatz großer finanzieller und personeller Ressourcen daran gearbeitet, dass Roboter die Fabrikhallen verlassen und Teil von Alltagswelten wie Krankenhäusern, Kindergärten und Privatwohnungen werden. Die Konstrukteurinnen und Konstrukteure stehen dabei vor einer nicht-trivialen Herausforderung: Sie müssen die Ambivalenzen und Kontingenzen alltäglicher Interaktion in die diskrete Sprache der Maschinen übersetzen. Wie sie dieser Herausforderung begegnen, welche Muster und Lösungen sie heranziehen und welche Implikationen für die Verwendung von Sozialrobotern dabei gelegt werden, ist der Gegenstand des Buches. Auf der Suche nach der Antwort, was Roboter sozial macht, hat Andreas Bischof Forschungslabore und Konferenzen in Europa und Nordamerika besucht und ethnografisch erforscht. Zu den wesentlichen Ergebnissen dieser Studie gehört die Typologisierung von Forschungszielen in der Sozialrobotik, eine epistemische Genealogie der Idee des Roboters in Alltagswelten, die Rekonstruktion der Bezüge zu 'echten' Alltagswelten in der Sozialrobotik-Entwicklung und die Analyse dreier Gattungen epistemischer Praktiken, derer sich die Ingenieurinnen und Ingenieure bedienen, um Roboter sozial zu machen.

Evidence-based practice behind the scenes : How evidence in social work is used and produced

Björk, Alexander January 2016 (has links)
The aim of this dissertation is to examine empirically what Evidence-based practice (EBP) and its standardized procedures become when put into practice in social work. EBP builds on the idea that professional practice should be based on systematic and reliable knowledge of the interventions and instruments used in this work. This implies a standardization of both research and practice that has been highly contested. Inspired by works within science and technology studies (STS), this dissertation analyses the actual content of the standardized procedures and their uses in social work practice. The dissertation examines a ‘critical case’, a substance abuse social services agency that has worked extensively for several years at implementing EBP, and consists of four papers focusing on three standardized procedures used by the agency in order to enact EBP: 1) the Addiction severity index (ASI) assessment instrument; 2) the psychosocial intervention Motivational interviewing, and 3) the decision-making model Critical appraisal (CA). Ethnographic methods were employed to study the agency’s concrete uses of the standardized procedures in daily practice. MI was also followed in the research literature as it became established as an ‘evidence-based’ intervention. Fundamentally, the development of the standards of EBP can be a messy and paradoxical process. In the stabilization of MI, its differences and ‘fluidity’ have eventually been made to disappear and left a stable ‘evidence-based’ object. Findings from the ethnographic studies show that EBP, as enacted in the agency’s daily practice, is a bureaucratic project where the agency’s managers have decided on and control the use of a set of standards. Thus, what constitutes relevant evidence is based not on professional discussion within the agency but is ultimately determined by the managers. In practice, the standards introduce new logics that cause tensions within the agency, tensions which the social workers are left to handle. Main conflicts concern how the client work is ordered and contradictory organizational rationales. The three standards are used to varying extent, which can be understood by examining what they seek to standardize and how they are put to work. CA was not used at all, mainly due to its design. Disregarding organizational rationales that are unavoidable within the social services, it could not be adapted to the agency’s work. With ASI and MI the situation was different, mostly because of their organizational adaptability. ASI could be implemented in several phases of the agency’s work flow resulting in adjustments of both the instrument and the work flow. As a ‘fluid intervention’, MI was constrained by, but also adjustable to the organization. It was thus possible for both ASI and MI to transform and be transformed by pre-existing practices, in effect creating new practices. A major conclusion is that EBP and its standardized procedures is a more dynamic and multifaceted process than previously acknowledged in social work. Rather than a deterministic one-way path, there are different kinds, degrees, and mutual transformations of standardization processes, which must be appreciated in research and in practical efforts to implement EBP. Given the importance of the organization in professional social work, there is a need to move away from individualistic conceptions of EBP and to consider what evidence use might mean from an organizational perspective. / <p>At the time of the doctoral defense, the following paper was unpublished and had a status as follows: Paper 4: Manuscript.</p>

Geospatial Data Accessibility in Web 2.0 Environments

McNamee, Sara Helen 01 May 2011 (has links)
Geographically referenced data is becoming a robust source of information because the use of place-based relevance searching is being employed as a popular form of information access and dispersal. To address this trend, the researcher conducted a study on the usability of the USA National Phenology Network (http://www.usanpn.org/), engaging 6 volunteer participants structured usability test of the USANPN mapping application. The participants were asked to complete two tasks, and data was collected both during (in the form of a think aloud exercise) and after the test (in the form of an exit interview). From the data collected, the researcher aimed to identify common and serious usability issues using both quantitative usability metrics and the qualitative think aloud and interview data. This study was primarily directed at assessing the usability of a geospatial Web 2.0 application and identifying common user problems. The researcher concluded that the search functionality and general navigation options were the most pressing usability issues associated with using the USA National Phenology Website to contribute geospatial data.

Taming Exotic Beauties : Swedish Hydro Power Constructions in Tanzania in the Era of Development Assistance, 1960s - 1990s

Öhman, May-Britt January 2007 (has links)
This study analyses the history of a large hydroelectric scheme – the Great Ruaha power project in Tanzania. The objective is to establish why and how this specific scheme came about, and as part of this to identify the key actors involved in the decision-making process, including the ideological contexts within which they acted. Although the Tanzanian actors and the World Bank (IBRD) are discussed, main focus is on the Swedish actors on project level.Kidatu, the first phase of the Great Ruaha power project (constructed between1970-1975), became the first large-scale hydropower station in Tanzania. As such, it paved the way for Tanzanian entrance into the Big Dam Era and significant changes within the Tanzanian landscape. As well as the dry river bed at Kidatu, and the small reservoir that precedes it, the Great Ruaha power project also involved the creation of a huge artificial lake, the Mtera reservoir. The Kidatu hydropower station was the first large undertaking within Swedish bilateral aid, and implied the takeover of control of hydropower construction in Tanzania by Swedish enterprises, replacing the enterprises of the former colonial power. A hydropower plant is a complex technoscientific artefact. The construction of a hydropower plant is preceded by a large number of technological choices, scientific prestudies and estimations of costs and revenues. A hydropower plant is also a complex social creation, and is as such filled with social actors engaged in conflicts, compromises and power structures. The decision to construct Kidatu hydropower station was a result of negotiations and activities within what is called “development assistance”. This brings in yet another dimension, the political one, involving export and import of technology, foreign capital, and foreign influence in decision-making processes, as well as ideas about how to bring development and progress to a people supposed to be living in “poverty and misery”. The study is divided into three main parts. The first part analyses the context of Swedish development assistance in the support to the construction of hydropower plants. This part discusses Swedish state-supported hydropower exploitation of indigenous people’s territory within Sweden’s borders in the 20th century and the background of Swedish development assistance, from the 1950s to the early 1960s. The second part analyses the event of Swedish development assistance entering Tanzania and the Great Ruaha power project, with the main focus being on the period 1965 – 1970. The third part is an analysis of the technoscientific basis for the decisions taken to implement the Great Ruaha hydropower scheme. Main focus is on the period 1969-1974, discussed against the backdrop of precolonial and colonial studies. While focus is on the 1960s and 1970s, in both part two and three events in the 1980s and 1990s are discussed. The study shows that although Sweden was not a colonial power in Tanzania, colonial imagery, and relations to the colonial era, as well as Sweden’s background of internal colonialisation, exerted an influence on the decision-making process and the actors involved in the Great Ruaha power project.The study is mainly based on archival sources, complemented with oral sources from Tanzania and Sweden. Recognizing the complexity of large-scale hydropower and the attempts to control watercourses that large scale hydropower necessitates, in the specific context of decolonisation and development assistance that the decision-making process behind the Great Ruaha hydropower scheme reveals, the analysis of the actors involved is based on feminist and postcolonial perspectives. / QC 20100825

Exploring socio-technical relations : perceptions of Saskatoon Transit’s go-pass smartcard and electronic fare system

2012 December 1900 (has links)
It is essential to consider what new technologies mean to the people who use them and the ways in which they are experienced and used. In the context of public transit services in Saskatoon, understanding what the recent changes from a manual to an electronic/automated system means to users and the broader community is critically important to the overall assessment of the service. Investigating users’ lived experiences and interpretations of technical artifacts is valuable to understanding socio-technical relations or the embodied interactions of humans and machines as “technologies-in-practice.” Research into socio-technical relations has primarily focused on large scale technological systems and expert practices while less attention has been paid to “seemingly mundane” technologies or technical artifacts routinely used in everyday life. At the same time, this preoccupation has overshadowed or downplayed the importance of exploring users’ experiences and interpretations of technologies. The goal of this research is to contribute to the sociological understanding of mundane technologies-in-practice and socio-technical relations more broadly. In order to gain insight into this relationship, this thesis focuses on bus riders’ (users) and the community’s perceptions of the Go-Pass smartcard and electronic fare system used by the public transit service in Saskatoon. The perspectives of Go-Pass users and community stakeholders (n=15) were investigated using qualitative semi-structured interviews to gain deeper understanding into the complex relationship between users and technologies. Drawing from Science and Technology Studies (STS) and the sociology of technology literature, I propose that a sociomaterial theoretical perspective following a mutual shaping framework offers insight into socio-technical relations. Both critical and feminist technology studies literature has been helpful for developing an understanding of the wider social and political contexts of technical use which underscores this study. In particular, the conceptual insights of “socio-technical assemblages” (Suchman, 2007) and “intra-action” (Barad, 2003) have been helpful tools for exploring agency, subjectivity and power which is key to uncovering the intricacies of socio-technical relations and human-machine interaction. The four main themes emerging from this study were: 1) shifting human-machine roles and relationships; 2) the socio-technical construction of the bus rider; 3) configuring users’ and technologies; and 4) structural issues and social justice implications of technologies-in-practice. The findings demonstrate that the use of this new system is mutually co-constructed by both social and technical factors whereby both the users and the technology inform perceptions and use. There was also the unexpected connection between users’ everyday situated uses, experiences and interpretations of the Go-Pass technologies to wider social-political contexts. There were a number of issues raised in relation to the implementation of the Go-Pass system which had negative effects or unintended social and technical consequences particularly for those most marginalized economically. At the same time, there were important benefits and positive effects on riders’ quality of life and use of the service. Finally, participants’ perspectives have contributed to understanding what the Go-Pass technologies mean to them, the ways in which they are used in practice and the ways in which the mixing of people and seemingly mundane technologies shape relations in everyday settings.

Alla ricerca del cinema perduto in Rete: il Webcinema / In search of lost cinema in the Net: the webcinema

MORTEO, MARZIA 26 June 2009 (has links)
L’obiettivo di questo lavoro è la ricostruzione di un oggetto mediale di cui ormai in Rete si sono perse le tracce: il webcinema, il cinema creato, realizzato e distribuito attraverso la Rete. Esso nasce e si sviluppa in una fase pionieristica del web tra la seconda metà degli anni novanta e i primi anni del XXI secolo, in un periodo segnato dalla sviluppo della tecnologia dello streaming che consentirà la trasmissione di contenuti sonori e audiovisivi attraverso la Rete, ridefinendo il concetto del web stesso da collezione di testi a flusso di informazioni audiovisive, l’euforia della net economy e lo scoppio della bolla delle dot-com. Per analizzare questo fenomeno ibrido, di cui la teorizzazione coeva è scarsa e di cui la Rete sembra essersi dimenticata, adottiamo l’approccio metodologico della Actor-network Theory che ci permetterà di investigare i veloci cambiamenti, l’instabilità e l’eterogeneità propria dei media digitali. Con l’analisi del case history verrà evidenziata la complessa relazione esistente tra dimensione tecnologica e dimensione sociale che nel caso dei media digitali è improntata a momenti di apertura nei confronti della innovazione e di stabilizzazione e definizione di determinati modelli d’uso. / Aim of this work is the reconstruction of a forgotten media by the Net: webcinema, cinema created specifically for viewing on the Internet. It is born and it develops in a pioneering phase of the web between the second half of the Nineties and first years of XXI century, in a period marked from the development of the streaming technology allowing the transmission of sound and audiovisual contents through the Net, redefining quite the concept of the web from collection of texts to audiovisual informational flux, net economy hype and the collapse of the dot-com bubble. In order to analyze this hybrid media object, barely studied by the contemporaneous scholarship and forgotten by the Net, we use the Actor-network theory approach that will allow to investigate the rapid changes, the instability and the heterogeneity of digital media. The case history will underline the complex relation between technological dimension and social dimension that digital media modellize in an opening approach versus innovation and a stabilization one versus some certain user models.

Valuation in Welfare Markets : The Rule Books, Whiteboards and Swivel Chairs of Care Choice Reform / Värdering på välfärdsmarknader : Regelböcker, whiteboardtavlor och snurrstolar i vårdvalsreform

Johansson Krafve, Linus January 2015 (has links)
This thesis takes an interest in how values attain a specific meaning in market reforms of welfare provision. The study builds on exploring how values are enacted rather than treating them as universal and stable. The aim of the thesis is to contribute conceptually to the understanding of how market-making activities in the welfare state bureaucracy handle the values at play in welfare reform. The empirical case is the governance of a so-called care choice system in a Swedish county council. The methodology for the study is “shadowing” of public officials working to formulate a so-called rulebook for care centres. The analysis describes how these officials handle a variety of values when designing the rulebook. How they choose to organize their work – the methods used to collect data about care centre performance, what governance tools they employ, how they arrange their work roles, and how they construct the rulebook – leads to value shifts and determines the meaning of values in practice. The officials’ work practice is political in the sense that it actively shapes the values enacted in the care choice reform. Therefore, it is of great importance to spur a broader debate about the organization of such governance practices, while there is a need to problematize simplistic images of what market reforms of welfare entails in practice. The thesis proposes that an “ecological” – i.e. a situated, reflexive, and malleable – approach to handling of contending values may contribute to such debates. / Avhandlingen intresserar sig för hur värden får sin praktiska innebörd i marknadsreformer av välfärdstjänster. Studien bygger på att undersöka hur värden blir lokalt iscensatta snarare än att behandla dem som universella och stabila. Syftet med studien är att utveckla begrepp för att förstå hur marknadsskapande styrning av välfärd hanterar de motstridiga värden som står på spel i välfärdsreform. Det empiriska fallet utgörs av styrningen av det s.k. vårdvalet i ett svenskt landsting. Metoden är ”skuggning” av tjänstemän som jobbar med att formulera en s.k. regelbok för vårdcentraler. Analysen beskriver hur dessa tjänstemän arbetar med att hantera olika typer av värden när de konstruerar regelboken. Hur de väljer att organisera sitt arbete – vilka metoder de använder för att samla in data om vårdcentralernas prestationer, vilka verktyg de använder för styrning, hur de ordnar sina arbetsroller, samt hur de konstruerar regelboken – leder till värdeförskjutningar och styr vilka uttryck de olika värdena får i praktiken. Tjänstemännens arbete är politiskt såtillvida att det aktivt formar de värden som får utrymme i vårdvalsreformen. Därför är det av stor vikt att skapa en bredare debatt kring organisering av sådan styrning, samtidigt som det kräver att man problematiserar förenklade bilder av vad marknadsreformer i välfärden betyder i praktiken. Avhandlingen föreslår att ett ”ekologiskt” – dvs. ett situerat, reflexivt och föränderligt – perspektiv på hanteringen av motstridiga värden i marknadsreformer kan bidra till en sådan debatt.

Constructing and fracturing alliances : actant stories and the Australian xenotransplantation network

Cook, Peta S. January 2008 (has links)
Xenotransplantation (XTP; animal-to-human transplantation) is a controversial technology of contemporary scientific, medical, ethical and social debate in Australia and internationally. The complexities of XTP encompass immunology, immunosuppression, physiology, technology (genetic engineering and cloning), microbiology, and animal/human relations. As a result of these controversies, the National Health and Medical Research Council (NHMRC), Australia, formed the Xenotransplantation Working Party (XWP) in 2001. The XWP was designed to advise the NHMRC on XTP, if and how it should proceed in Australia, and to provide draft regulatory guidelines. During the period 2001-2004, the XWP produced three publicly available documents one of which, ‘Animal-to-Human Transplantation Research: A Guide for the Community’ (2003), was specifically designed to introduce the general public to the major issues and background of XTP. This thesis examines XTP in Australia as guided and influenced by this community document. Explicitly, drawing upon actor (actant)- network theory, I will reveal the Australian XTP network and explore, describe and explain XTP problematisations and network negotiations by the enrolled actants on two key concepts and obligatory passage points - animals and risk. These actants include those providing regulatory advice (members of the XWP and the associated Animal Issues Subcommittee), those developing and/or critiquing XTP (official science and scientists), and those targeted by the technology (people on dialysis, with Type-1 diabetes, Huntington’s disease, Parkinson’s disease, pre-or post-human-tohuman transplantation, and their partner/spouse). The stories are gathered through focus groups, semi-structured interviews and document analysis. They reveal ambiguous and sometimes contradictory stories about animals and risk, which influence and impact the problematisations of XTP and its networks. Therefore, XTP mobilises tension; facilitating both support and apprehension of the XTP network and its construction by both the sciences and the publics.

Who Will Be the First to Buy Autonomous Vehicles? An Application of Everett Rogers’ Diffusion of Innovations Theory

Umberger, Reilly Jackson 01 January 2016 (has links)
Autonomous, otherwise known as self-driving, vehicles represent the future of transportation. Vehicles that drive themselves offer far reaching benefits from increased leisure and productivity for individuals to significant improvements in congestion and infrastructure for governments. The autonomous car will radically change the way we look at transportation, and they are right around the corner. However, the question remains: are we ready? Are we, as a society, ready to hand over the steering the wheel and trust autonomous vehicles with our safety? This paper predicts how the autonomous car will spread through society by analyzing and applying the product qualities and consumer types described in Everett Rogers’ Diffusion of Innovations Theory. Corporations, specifically Uber and Amazon, as opposed to individual consumers, will be the first to adapt, purchase and implement autonomous vehicles. Contrary to popular belief, these vehicles will not be successfully introduced as privately owned vehicles, and therefore, must be marketed towards corporations and organizations.
