Toward a “Green” Organ: Organ Building and Sustainability

January 2014 (has links)
abstract: This study examines the effectiveness of various types of alternative resources in organ building in order to determine whether a change to more sustainable materials would benefit or hinder the overall sound production of the instrument. The qualities of the metals and woods currently used in organ production (e.g. lead, walnut, etc.) have been prized for centuries, so the substitution of different, more sustainable materials must be considered with regards to the sonic alterations, as well as the financial implications, of using alternatives to make the organ more “green.” Five organ builders were interviewed regarding their views on sustainable materials. In addition, the author consulted the websites of nine national and four international organ builders for information about sustainability, indicating that each organ builder defines the term somewhat differently. Decisions on the woods and metals to be used in building or refurbishing an existing organ are based more on the visual appearance, the sound desired, and the potential for reuse of existing materials. A number of sustainability practices are currently in use by organ builders in the United States and Europe. These include the reuse of transportation boxes, efforts towards recycled metal and wood pipework, and the use of high efficiency lighting. The investigations into sustainable practice that are presented here document a variety of approaches to sustainability in organ building in the United States, Canada and Europe. This research should assist in the evaluation of further efforts to conserve valuable resources while ensuring the high quality of sound that has characterized the organ throughout its long history. / Dissertation/Thesis / Doctoral Dissertation Music 2014

Social and Cultural Drivers of Meat Consumption among Mexican-American Millennials in Tempe, AZ

January 2014 (has links)
abstract: The rise of meat consumption in the United States has been dramatic over the past half century due to demographic changes. The increase in meat is visible in Mexico as well due to expanding economic interest in cattle production plus increased population and rising incomes. The worst consequences of our modern food system are in factory farming of animals, which requires a greater amount of resources than for producing grains, fruits, and vegetables. The specific effects of meat consumption highlight the importance of understanding humans as actors in the food system. In order to explore the drivers of consumer food and meat choice, my research answered the two questions: What factors influence meat consumption? and How do cultural and social norms influence decisions to consume certain types and amounts of meat? Qualitative interviews were conducted with Mexican-American respondents between age 20 and 29 as the population of interest because of their regional dominance in the study area of Tempe, AZ and because of the high prevalence of meat in their cultural diets. Looking at millennials in particular is crucial because as the first generation born with technology and Internet as constants, they have formed unique characteristics like openness to change and new perspectives. My sample population communicated motivations and constraints to their overall consumption patterns and the frequency and types of meat consumed. This study found that cost and convenience were the driving factors behind food choice, given the hectic schedules of the sample population, who were mostly students at Arizona State University. Culture played an important role in respondents' heavy meat consumption given their exposure to meat's centrality in traditional Mexican meals. Acculturation did not play an extensive role because prominent Mexican culture in the Southwest U.S. allowed respondents' families access to traditional food while living in the US. The lack of sustainability knowledge and its connection to food choice indicates the importance of marketing that contextualizes decreased meat consumption. Rather than focusing solely on environmental outcomes, marketing tools highlighting health, financial, and economic benefits of eating less meat would encourage more consumers to decrease consumption. / Dissertation/Thesis / Masters Thesis Sustainability 2014

A Thoughtful Journey Toward Sustainable Choice: Can Mindfulness Enhance Behavior Intent?

January 2017 (has links)
abstract: ABSTRACT The tourism industry continues to mature as many consumers are demanding more responsible and sustainable development. Mindfulness has been studied in tourism as a cognitive trait recognized by actively processing information through an acute sensitivity to an individual's environment and openness to new information. Mindfulness has been shown to predict behaviors related to tourism and recreation. The Theory of Planned Behavior (TPB) has been extensively applied to understand human behavior. Despite TPB's extensive history in the social sciences, researchers continue to incorporate new social factors to explain behavior. This study employs an emerging psychological construct, mindfulness, into the TPB model as an enhancement to conceptual and empirical discrepancies. This study aimed to: (1) understand the presence of mindfulness among those who travel, and (2) test a hypothesized relationship between mindfulness and intent to be sustainable on vacation. The research seeks to answer - does mindfulness add to a traveler's likelihood to behave sustainably in a destination with active sustainable initiatives? The purpose of this study is to showcase emerging consumer traits, like mindfulness, to enhance visitor experiences through sustainability initiatives. A survey research method was employed to provide a broad, generalizable set of findings from a group of people who were planning a trip and may have visited a specific destination. This study partnered with Sedona Chamber of Commerce and Tourism Bureau to access such a population. The survey was conducted with a self-administered online survey and 550 completed surveys were obtained. Behavior intention to be sustainable, in any visited destination, was regressed twice to address the research question. The first regression included original TPB independent variables (such as attitude, social norms, perceived behavioral control). The second regression added the mindfulness variable. The mindfulness variable was found to be positive and significant in a general context. The model was tested for those who traveled to Sedona and mindfulness and actual behaviors associated with sustainability were strongly related. A traveler's perception of their ability to control behaviors had a significant role when paired with mindfulness. Results suggest the TPB model has availability to incorporate new consumer behavior traits to understand behavior intention. / Dissertation/Thesis / Masters Thesis Community Resources and Development 2017

Small Business Participation in Sustainable Tourism Certification: Internal and External Influences

January 2017 (has links)
abstract: As the number of travelers around the world grows, the importance of managing tourism destinations in a sustainable manner becomes increasingly important. Sustainable tourism has long been discussed as necessary for managing tourism responsibly, yet adoption of sustainable strategies and operationalization has been slow. Initiatives and programs often focus on environmental components of sustainability and the role of large companies. Certification programs are one way in which destinations are operationalizing community-wide sustainable tourism and small businesses are engaging in sustainability initiatives and recognition. Using social cognitive theory as the research framework, this study examined internal and external motives and their influence on small business participation in sustainable tourism certification and sustainability practices. Incentives for behavior, modeling of other businesses, company values, and self-efficacy were examined as motives and barriers. Regression analysis and independent samples t-tests were used to examine statistical relationships. This study partnered with the Alaska Travel Industry Association (ATIA) to study businesses that hold Adventure Green Alaska sustainable tourism certification or are viewed as prospects for certification. From a list of 77, 44 Alaska tourism businesses responded to an online questionnaire to participate in this study. Businesses were categorized into those with certification (n = 31) and those without (n=13). Results indicated participation in sustainability practices to be higher among certified businesses than non-certified. Internal motives indicated to be more significant than external motives for participation in sustainable practices and certification. Company values were of high importance to both certified and non-certified businesses in implementing sustainable practices and certification. Consumer interest and marketing benefits were important incentives for participation in sustainability strategies. These findings have implications for tourism industry associations and organizations interested in the operationalization and development of sustainable tourism. This study is expected to aid in marketing and retention efforts for sustainable tourism certification programs, as well as future direction for development of sustainable tourism certification. / Dissertation/Thesis / Masters Thesis Community Resources and Development 2017

Desenvolvimento de metodologia de análise de indicadores de sustentabilidade como ferramenta para tomada de decisão utilizando lógica fuzzy / A methodology approach for analysis of sustainability indicators as a tool for decision making using fuzzy logic

Fernando Henrique Franchi Quinhoneiro 23 October 2015 (has links)
O maior desafio desse século tem como tema central a sustentabilidade, devido ao crescimento da população mundial e consequentemente ao aumento da demanda por recursos, como água, alimento e energia. A principal dificuldade quando se debate a questão do Desenvolvimento Sustentável está na metodologia de avaliação. Daí a necessidade de criar um instrumento de mensuração que aborde estes recursos de uma maneira holística e que seja capaz de traduzir dados em um resultado passível de interpretação. Existem ferramentas validadas para esse objetivo como DashBoard of Sustainability e outras em desenvolvimento como a Metodologia CLEW pela Agência Internacional de Energia Atômica IAEA. Este estudo tem como objetivo desenvolver um novo modelo de análise de correlação entre as variáveis, energia, água, uso do solo e clima, utilizando Inteligência Artificial, através da Lógica Fuzzy, tendo como base de dados, indicadores que representem um ou mais recursos, considerando uma distribuição temporal relativa e necessária para a investigação de resultados e comportamentos. O resultado será um índice final gerado através do mapeamento destes dados de entrada. Os resultados apresentados utilizando essa metodologia são de indicadores do Brasil, porém pode ser aplicada a qualquer outro país, permitindo uma análise de comparação do comportamento dos índices entre regiões. A contribuição desse projeto será a disponibilidade de uma ferramenta, com recurso computacional poderoso, destinada aos tomadores de decisão para auxiliar no desenvolvimento de estratégias e políticas de desenvolvimento. / The greatest challenge of this century is focused on sustainability, due to world population growth and consequently to the increased demand for resources such as water, food and energy. The main difficulty when discussing the issue of sustainable development is the evaluation methodology. Because of this, there is a need for a measurement tool that addresses these resources in a holistic manner and be able to translate data into results that can be interpreted. There are tools validated for this purpose like, \"Dashboard of Sustainability\" and other developing like the CLEW Nexus by the International Atomic Energy Agency - IAEA. This study aims to develop a new model to analyze the correlation between variables, energy, water, land use and climate, using Artificial Intelligence through Fuzzy Logic, having as a data source, indicators that represent one or more resource, considering the relative and temporal distribution required to research results and behaviors. The result is a final index generated by mapping these input data. The results presented using this methodology are indicators of Brazil, but can be applied to any other country, allowing a comparison analysis of the behavior of indices between regions. The contribution of this project will be the availability of a tool with powerful computational resource, aimed at decision makers to assist in developing strategies and development policies.

Sustainability Implications of Mass Rapid Transit on the Built Environment and Human Travel Behavior in Suburban Neighborhoods: The Beijing Case

January 2012 (has links)
abstract: The sustainability impacts of the extension of the Mass Rapid Transit (MRT) system in suburban Beijing are explored. The research focuses on the neighborhood level, assessing sustainability impacts in terms of greenhouse gas emissions, air pollution, and energy consumption. By emphasizing suburban neighborhoods, the research targets the longest commuting trips, which have the most potential to generate significant sustainability benefits. The methodology triangulates analyses of urban and transportation plans, secondary data, time series spatial imagery, household surveys, and field observation. Three suburban neighborhoods were selected as case studies. Findings include the fact that MRT access stimulates residential development significantly, while having limited impact in terms of commercial or mixed-use (transit-oriented development) property development. While large-scale changes in land use and urban form attributable to MRT access are rare once an area is built up, adaptation occurs in the functions of buildings and areas near MRT stations, such as the emergence of first floor commercial uses in residential buildings. However, station precincts also attract street vendors, tricycles, illegal taxis and unregulated car parking, often impeding access and making immediate surroundings of MRT stations unattractive, perhaps accounting for the lack of significant accessibility premiums (identified by the researcher) near MRT stations in suburban Beijing. Household-based travel behavior surveys reveal that public transport, i.e., MRT and buses, accounts for over half of all commuting trips in the three case study suburban neighborhoods. Over 30% of the residents spend over an hour commuting to work, reflecting the prevalence of long-distance commutes, associated with a dearth of workplaces in suburban Beijing. Non-commuting trips surprisingly tell a different story, a large portion of the residents choose to drive because they are less restrained by travel time. The observed increase of the share of MRT trips to work generates significant benefits in terms of lowered energy consumption, reduced greenhouse gas and traditional air pollution emissions. But such savings could be easily offset if the share of driving trips increases with growing affluence, given the high emission intensities of cars. Bus use is found to be responsible for high local conventional air pollution, indicating that the current bus fleet in Beijing should be phased out and replaced by cleaner buses. Policy implications are put forward based on these findings. The Intellectual Merit of this study centers on increased understanding of the relationship between mass transit provision and sustainability outcomes in suburban metropolitan China. Despite its importance, little research of this genre has been undertaken in China. This study is unique because it focuses on the intermediate meso scale, where adaptation occurs more quickly and dramatically, and is easier to identify. / Dissertation/Thesis / Ph.D. Sustainability 2012

Cultural Sustainability by Design: A Case of Food Systems in India

January 2013 (has links)
abstract: In response to the rapid rise of emerging markets, shorter product lifecycles, increasing global exchange and worldwide competition, companies are implementing `sustainable development' as a mechanism by which to maintain competitive global advantage. Sustainable product development approaches used in industry focus mainly on environmental issues, and to a certain extent on social and economic aspects. Unfortunately, companies have often ignored or are unsure of how to deal with the cultural dimensions of sustainable product development. Multi-nationals expanding their business across international boundaries are agents of cultural change and should be cognizant of the impact their products have on local markets. Companies need to develop a deeper understanding of local cultures in order to design and deliver products that are not only economically viable but also culturally appropriate. To demonstrate applicability of cultural appropriate design, this research undertakes a case study of food systems in India specifically focusing on the exchange of fresh fruits and vegetables (FFV). This study focuses on understanding the entire supply chain of FFV exchange, which includes consumer experiences, distribution practices and production processes. This study also compares different distribution channels and exchange practices and analyzes the pattern of authority between different players within the distribution network. The ethnographic methods for data collection included a photo-journal assignment, shop-along visits, semi-structured interviews, a participatory design activity and focus group studies. The study revealed that traditional retail formats like pushcart vendors, street retailers and city retail markets are generally preferred over modern retail stores. For consumers, shopping is a non-choreographed activity often resulting in exercising, socializing and accidental purchases. Informal communication, personal relationships and openness to bargaining were important aspects of the consumer-retailer relationship. This study presents cultural insights into interactions, artifacts and contexts relevant to FFV systems in India. It also presents key implications for the field of design, design research, cultural studies, consumer research and sustainability. The insights gained from this study will act as guidelines for designers, researchers and corporations interested in designing products and services that are culturally appropriate to contexts of production, distribution and consumption. / Dissertation/Thesis / Ph.D. Design 2013

A Method for Sustainability Appraisal of Urban Visions

January 2013 (has links)
abstract: Over the last two decades programs and mandates to encourage and foster sustainable urban development have arisen throughout the world, as cities have emerged as key opportunity sites for sustainable development due to the compactness and localization of services and resources. In order to recognize this potential, scholars and practitioners have turned to the practice of visioning as a way to motivate actions and decision making toward a sustainable future. A "vision" is defined as desirable state in the future and scholars believe that the creation of a shared, motivational vision is the best starting point to catalyze positive and sustainable change. However, recent studies on city visions indicate that they do not offer substantive sustainability content, and methods or processes to evaluate the sustainability content of the resulting vision (sustainability appraisal or assessment) are often absent from the visioning process. Thus, this paper explores methods for sustainability appraisal and their potential contributions to (and in) visioning. The goal is to uncover the elements of a robust sustainability appraisal and integrate them into the visioning process. I propose an integrated sustainability appraisal procedure based on sustainability criteria, indicators, and targets as part of a visioning methodology that was developed by a team of researchers at Arizona State University (ASU) of which I was a part. I demonstrate the applicability of the appraisal method in a case study of visioning in Phoenix, Arizona. The proposed method allows for early and frequent consideration and evaluation of sustainability objectives for urban development throughout the visioning process and will result in more sustainability-oriented visions. Further, it can allow for better measurement and monitoring of progress towards sustainability goals, which can make the goals more tangible and lead to more accountability for making progress towards the development of more sustainable cities in the future. / Dissertation/Thesis / M.S.

Crafting Sustainability Visions - Integrating Visioning Practice, Research, and Education

January 2013 (has links)
abstract: Sustainability visioning (i.e. the construction of sustainable future states) is considered an important component of sustainability research, for instance, in transformational sustainability science or in planning for urban sustainability. Visioning frees sustainability research from the dominant focus on analyzing problem constellations and opens it towards positive contributions to social innovation and transformation. Calls are repeatedly made for visions that can guide us towards sustainable futures. Scattered across a broad range of fields (i.e. business, non-government organization, land-use management, natural resource management, sustainability science, urban and regional planning) are an abundance of visioning studies. However, among the few evaluative studies in the literature there are apparent deficits in both the research and practice of visioning that curtails our expectations and prospects of realizing process-based and product-derived outcomes. These deficits suggests that calls instead should focus on the development of applied and theoretical understanding of crafting sustainability visions, enhancing the rigor and robustness of visioning methodology, and on integrating practice, research, and education for collaborative sustainability visioning. From an analysis of prominent visioning and sustainability visioning studies in the literature, this dissertation articulates what is sustainability visioning and synthesizes a conceptual framework for criteria-based design and evaluation of sustainability visioning studies. While current visioning methodologies comply with some of these guidelines, none adhere to all of them. From this research, a novel sustainability visioning methodology is designed to address this gap to craft visions that are shared, systemic, principles-based, action-oriented, relevant, and creative (i.e. SPARC visioning methodology) and evaluated across all quality criteria. Empirical studies were conducted to test and apply the conceptual and methodological frameworks -- with an emphasis on enhancing the rigor and robustness in real world visioning processes for urban planning and teaching sustainability competencies. In-depth descriptions of the collaborative visioning studies demonstrate tangible outcomes for: (a) implementing the above sustainability visioning methodology, including evaluative procedures; (b) adopting meaningful interactive engagement procedures; (c) integrating advanced analytical modeling, sustainability appraisal, and creativity enhancing procedures; and (d) developing perspective and methodological capacity for long-range sustainability planning. / Dissertation/Thesis / Ph.D. Sustainability 2013
