Full textAbstract:
The city of Melbourne in Victoria, Australia has been recognised as having high quality drinking water, but like other urban cities in the world, its growing population means increasing water demand. Melbourne is also already on its eight year of dry climatic conditions and is currently experiencing a drought that forced water authorities to impose water restrictions after 20 years of unrestricted supply. The current drought, dwindling supplies and possible impact of climate change highlight the importance of making better use of this precious resource. The Water Resources Strategy has been developed for Melbourne, which serve as the basis for the Victorian Government to set per capita consumption reduction targets of 15%, 25% and 30% by 2010, 2015 and 2020 respectively. The strategy was developed to ensure a continuation of a safe, reliable and cost effective water supply that is environmentally sustainable in the long term. This is in recognition that population growth and water consumption will eventually require additional supplies of water (Water Resources Strategy Committee for the Melbourne Area 2002). One of the key findings of the National Land and Water Resources Audit's Australian Water Resources Assessment 2000 is the lack of detailed knowledge about the end use (Australian Water Association 2001).

Thesis (S.M. in Technology and Policy)-- Massachusetts Institute of Technology, Engineering Systems Division, Technology and Policy Program, 2012.Cataloged from PDF version of thesis.
Includes bibliographical references (p. 59-60).
The residential sector in the U.S. is responsible for about 20% of the country's primary energy use (EIA, 2011). Studies estimate that efficiency improvements in this sector can reduce household energy consumption by over 25% by 2020 (McKinsey Global Energy and Materials, 2009). In this thesis, given the increasing amount of attention that both policy-makers and industry are giving to residential energy use, I examine the implications of end-use electrification and efficiency improvements in households. In particular, I focus on high efficiency electric technologies for heating and cooling (referred to as HVAC) needs. Advancements in technologies such as heat pumps are beginning to make the economic case for switching from end-uses of gas to end-uses of electricity in the residential sector. I examine the implications of such end-use electrification, ranging from its impact on energy consumption to its contribution to the abatement of greenhouse gas (GHG) emissions. I use the MIT Emissions Prediction and Policy Analysis (EPPA) model, a computable general equilibrium model, to analyze the research question. The EPPA model captures full economy-wide impacts of policy mandates and technology changes. First, I added further detail to household energy consumption in the model. Then, I introduced technology changes corresponding to advanced electric technologies for residential heating and cooling and tested their impact with policies that either support or inhibit their entry into the marketplace. I find two interesting results from the analysis. First, if policies are enacted to support advanced electric HVAC technologies, they displace end-uses of gas and increase household electricity consumption. Second, household end-use electrification in the U.S. leads to an increase in overall emissions in the economy, given that the overall emissions of any electric appliance depend not only on the end-use efficiency of the appliance but also on the efficiency of generating and distributing electricity. Thus, end use electrification only helps in emissions abatement if the power sector becomes less carbon intensive.

Full textAbstract:
Network simulations often output a log file, which must be parsed to understand the details of the simulation. Visualizations of these simulations are used to make debugging and analysis easier, and there are many visualizers that will display the simulation in 2D. Those in 3D do not fully utilize 3D graphics operations to visualize asimulation. This thesis explores the ways 3D graphics can be used to further enhance a visualization. To do this, it introduces a new network simulator and a visualizer, consisting of an analyzer, which collects statistics about a simulation, and a renderer, which leverages an existing program package for rendering.

Full textAbstract:
Purpose –The purpose of this research is to increase knowledge about how a led fitting impacts the environment. To be able to fulfil the purpose, it has been broken down into four research questions: • RQ1: What is the environmental impact during transportation? • RQ2: What is the environmental impact during the use phase? • RQ3: What is the environmental impact during the end of life phase? • RQ4: How can the environmental impact be decreased? Method: The authors worked abductive in the relation between theories and empirical data. The authors conducted a case study at a Swedish company in Jönköping. The case study covers a Life Cycle Analysis (LCA). The LCA includes four different stages; goal, scope & boundary definition, life-cycle inventory analysis, life cycle impact assessment and interpretation. During the stages the authors carried out a pre study, interview, document study and calculations. To find out more information about the problem area a literature study was conducted. Theoretical material was received from books, peer review articles and reports. The literature study and the case study increased the authors knowledge to answer the research questions. Findings: The research findings indicate that transportation, Use- and end of life phase impact the environment in different amounts of greenhouse gases (CO2e). The transportation from production to customer stands for 0,16 kg CO2e, the use phase for 15,6 kg CO2e and end of life for 0,5 kg CO2e. The environmental impact can be decreased if companies both deal with the issue to make products more sustainable during the entire life cycle. The transportation’s environmental impact can be decreased through reduction of CO2 emission, which is the dominated greenhouse gases during road freight transportation. The use phase environmental impact can be decreased if adapting a more efficient consumption system. Another way to minimize the environmental impact is to offer and implement maintenance and repairing. The end of life environmental impact can be decreased by recycling or reuse the materials. Another way to lower the impact is to have a holistic perspective when choosing material. Lastly the impact can be decreased if companies, already in the design stage to think about the products last phase. Implications: The practical implications in this study is the case study. The case study contributed with knowledge about the environmental impact of a led fitting. The study has not contributed with any new theories. The study is based on a problem statement with already amount of existing theories and developed tools to calculate the environmental impact. Even if the study did not contribute theoretically, it strengthens already existing theories or statement from other researchers. Limitations: The research ability to generalize can be questioned since the research was limited to a single case study. This can affect the generalizability of the result. Keywords – Sustainability, Environmental impact, LCA, led fitting, Life cycle, use phase, end of life phase, transportation, Carbon dioxide equivalent (CO2e)

Full textAbstract:
Context Spyware is “computer software that obtains information from a user's computer without the user's knowledge or consent” [25]. Spyware is often embedded in another application and is usually stated in End User License Agreement (EULA) [20]. However it is quite common to accept the EULA without even reading it. Therefore beside the traditional spyware analysis techniques, automated EULA analysis can be helpful for common users in order to identify the spyware [18]. Objectives The techniques of automated EULA analysis do exist however the process of taking a binary application, analyze it, and prepare it in order to extract the EULA has not been studied in existing research. There is a need for such a tool that can extract and analyze the EULA text from an installer binary without executing it. Objectives of this research are to investigate the techniques to unpack the binary file, extract the EULA, analyze it and present the analysis results to the end user. Methods In order to establish basic understanding of the related concepts preliminary study is done. In this study a number of article sources are used, including ACM Digital Library, Compendex, Inspec, IEEE Xplore, and Springer Link. Material has been selected after reading titles and summaries. Prototype of an open source tool is designed and developed. This tool extracts the EULA from executable binary installers, analyzes the extracted text and gives suggestions about legitimate level of the software. Results To evaluate our application we downloaded 150 executables from different web sites, which were already classified as bad or good by [23]. We used our tool to extract EULA text from executables. We were able to extract EULA from 48 percent of selected binary files. Analysis of extracted EULAs was also done to classify the software as good or bad. This analysis assists the user to make a decision to accept or reject the installation of software without reading even a single word of EULA. During the extraction and analysis process there was no significant impact on performance of the host system. Conclusion We conclude that EULA can be extracted from a binary file without executing it. However because of limited time it was not possible to extract EULA from all installer binaries. The rate of EULA extraction can be improved in future research.

Mestrado em Electrónica e TelecomunicaçõesA Qualidade de Serviço (QoS) é uma preocupação para os operadores, mas devido à evolução da rede para um enorme número de serviços com requisistos diferentes, garantir uma boa QoS não é exatcamente sinónimo de utilizadores satisfeitos. A percepção da qualidade de serviço por parte dos utilizadores (QoE) garante aos operadores uma visão do grau de satisfação do utilizador final. O objectivo de uma boa QoS deve ser promover uma melhor QoE nos utilizadores. A QoE permite aos operadores saberem de que forma é que as condições da rede satisfazem as expectativas dos seus utilizadores em termos de confiança, disponibilidade, escalabilidade, velocidade, desempenho e eficiência. O objectivo deste trabalho é o desenvolvimento de mecanismos que permitam aos operadores analisarem ao mesmo tempo o comportamento dos utilizadores e o estado da rede em termos de qualidade numa determinada região. Com este tipo de informação disponível os operadores podem adaptar os mecanismos de QoS da rede de modo a prencherem na totalidade as expectativas do utilizador final numa determinada região.
The Quality of Service (QoS) is already a major concern for operators, but things are changing and, although in many cases better QoS results in better Quality of Experience (QoE), fulfilling the required performance parameters is not a synonym of satisfied users. QoE conditions can immediate response on the user satisfaction and thus the goal of QoS assurance should be to promote a better QoE. This will give the operator a deeper sense of the contribution of network’s performance to the overall level of customer satisfaction in terms of reliability, availability, scalability, speed, accuracy and efficiency. The main goal of this work is to provide operators with mechanisms for end user behaviour analysis and at the same instant detailed network status. With this information operators know the end users behaviour in a certain region, know in detail network performance metrics and can adapt QoS mechanisms to fulfil end users expectations.

Full textAbstract:
En Corée, les quartzs sont utilisés intensivement parmi les matières premières au cours de toutes les périodes du Paléolithique. Nous souhaitons vérifier les caractéristiques ou les différences des fonctions d’outils en quartz selon les sites paléolithiques de périodes différentes et de diverses régions par des analyses fonctionnelles. Nous avons également étudié les variations dans l’utilisation d’un type d’outil particulier en fonction des sites : nous avons sélectionné le grattoir. Par les résultats de l'analyse fonctionnelle, des différences d’utilisations des outils en quartz entre les niveaux ne sont pas attestées, il existe une continuité dans l’utilisation au fil des niveaux. Cependant, les utilisations de l’outil en quartz sont légèrement différentes entre les sites analysés. La plupart des grattoirs ont été utilisés dans le travail de la peau. Cependant, nous pouvons observer des traces formées par une variété de tâches sur les grattoirs grands et épais. Autrement dit, nous pouvons attester que l'on utilise les grattoirs différemment en fonction de leurs dimensions. Sur la base de ce travail, d’autres études devraient être effectuées afin de trouver une réponse plus précise sur l’absence de changement entre les niveaux de nos sites d’étudeIt is necessary to examine quartz tools for understanding the Palaeolithic culture in Korea. It is difficult to identify the temporal change pattern of raw materials, assemblages and production techniques of stone tools found in the Palaeolithic sites in Korea ranging from the early to late Palaeolithic, because most stones tools uncovered from these sites are made of quartz. Therefore, this research raises two questions: Is it be possible that the use-wear analysis could reveal the functional change patterns of stone tools in accordance with production dates and environmental changes? How it can be detected the peculiar characteristics of the particular tools found in each site? The results of the use-wear analyses to each cultural layer show no clear temporal differences of raw materials, assemblages and uses of lithic tools. The sites where the excavated tools were mainly composed of quartz exhibited the successive patterns rather than the particular changes between cultural layers. The use-wear analysis suggest that most end-scrapers were used for processing hides. However, it could be observed use-wear pattern formed by processing woods and antlers in large-sized end-scrapers. Therefore, it can be inferred that the use of end-scrapers depended on the size of these tools; but it seems that small-sized end-scrapers produced in the late Palaeolithic were closely related to work hide. In order to seek more clear answers to this result, it will be needed to conduct analyses on many Palaeolithic sites dating to the transitional era distributed in different regions and on the sites yielding tools made of different raw materials
선사고고학은 기본적으로 선사인들의 생활과 환경에 대해 이해하기 위한 학문으로, 석기를 왜 만들고, 어떻게 사용했는가 ? 라는 기초적인 질문을 가진다. 다양한 연구 방법 가운데 석기에 남겨진 흔적을 연구하는‘쓴자국 분석’을 바탕으로 이에 대한 해답을 찾고자 한다. 한국에서는 시대와 지역이 다른 대다수의 구석기 유적에서 석영 석기가 높은 비율로 출토된다. 그렇기 때문에 한국의 구석기 문화에 대한 이해를 하기 위해서는 반드시 석영 석기에 대한 이해가 필수적이다. 이번 연구에서는 석영 석기에 대한 쓴자국 분석의 가능성을 확인하고 이를 통해 한국 구석기 유적에서 출토되는 석영석기의 기능과 시기와 환경에 따른 차이를 확인하고자 한다. 그리고 석영석기가 주를 이루는 한국의 구석기 유적에서는 구석기시대 전기에서 후기에 이르기까지 돌감, 석기의 구성, 제작기술 등에 있어 시기적인 변화와 특징을 확인하기 어렵기 때문에 쓴자국 분석을 통해 시기, 환경에 따른 석기의 기능에 있어서 차이 또는 특징들을 확인할 수 없는가? 그리고 유적에 따른 특정 도구의 사용에 차이 또는 특징들이 있는가? 라는 질문으로 시작한다. 그리고 석영석기에 대한 이해를 위해 다양한 실험을 통해 여러 작업재료에 따른 흔적들의 특징을 이해한다.먼저 여러 유물층이 확인되는 김포 풍곡리, 동탄 오산리와 청계리 구석기 유적의 석기들에 대해 분석 및 비교를 하였다. 그 결과 시간의 흐름에 따른 유물층에서는 사용되는 돌감, 석기구성과 사용 등에 있어 각 문화층에 따른 특징적인 차이를 명확하게 확인할 수 없었다. 쓴자국 분석을 통해 차이를 확인하고자 하였으나 석영 석기를 주로 사용하는 유적에서는 유적내 유물층 사이에서는 특별한 변화보다는 연속적인 양상을 볼 수 있었다. 도구와 유적의 기능과의 관계를 이해하기 위해 유적에서 출토되는 다양한 석기 가운데 지역과 시기에 상관없이 주로 출토되는 석기인 밀개에 대한 분석을 위해 7개 유적에서 출토된 밀개를 분석, 비교를 하였다. 그 결과 대부분의 밀개들이 가죽작업에 특징적으로 사용되었던 도구였을 것으로 짐작할 수 있다. 다만 크기가 큰 밀개의 경우 나무, 뿔 등 다양한 작업에 의해 형성된 흔적들을 볼 수 있었다. 즉, 밀개는 도구의 크기에 따라 다르게 사용이 이루어진 것으로 볼 수 있으나 후기 구석기 시대의 작은 크기의 밀개는 가죽 작업과 밀접한 관계가 있는 것으로 보인다. 일부 분석 유적들은 시기적으로는 후기에 해당하는 유적이지만, 후기 구석기로의 돌감선택, 도구의 소형화 등의 전환기적 특징이 확인되지 않았다. 또한 이번 분석 결과를 통해 석영 석기가 주로 출토되는 구석기 유적에서는 시간의 흐름에 따른 지속성을 확인 할 수 있었다. 이러한 결과가 분석이 이루어진 지역적인 특징인지, 석영이라는 돌감의 사용과 관련된 것인지에 대한 연구가 필요하며, 이를 바탕으로 유적의 지속적인 양상들에 대한 좀 더 명확한 해답을 찾기 위해서는 전환기에 해당하는 여러 지역의 다양한 구석기 유적들에 대한 분석과 석영이 아닌 다른 돌감이 주로 활용된 유적에 대한 연구와 비교가 더 필요하다

Full textAbstract:
Service composition has risen from the need to make information systems more flexible and open. The Service Oriented Architecture has become the reference architecture model for applications carried by the impetus of Internet (Web). In fact, information systems are able to expose interfaces through the Web which has increased the number of available Web services. On the other hand, with the emergence of the Web 2.0, service composition has evolved toward web users with limited technical skills. Those end-users, named Y generation, are participating, creating, sharing and commenting content through the Web. This evolution in service composition is translated by the reference paradigm of Mashup and Mashup editors such as Yahoo Pipes! This paradigm has established the service composition within end users community enabling them to meet their own needs, for instance by creating applications that do not exist. Additionally, Web 2.0 has brought also its social dimension, allowing users to interact, either directly through the online social networks or indirectly by sharing, modifying content, or adding metadata. In this context, this thesis aims to support the evolving concept of service composition through meaningful contributions. The main contribution of this thesis is indeed the introduction of the social dimension within the process of building a composite service through end users' dedicated environments. In fact, this concept of social dimension considers the activity of compositing services (creating a Mashup) as a social activity. This activity reveals social links between users based on their similarity in selecting and combining services. These links could be an interesting dissemination means of expertise, accumulated by users when compositing services. In other terms, based on frequent composition patterns, and similarity between users, when a user is editing a Mashup, dynamic recommendations are proposed. These recommendations aim to complete the initial part of Mashup already introduced by the user. This concept has been explored through (i) a step-by-step Mashup completion by recommending a single service at each step, and (ii) a full Mashup completion approaches by recommending the whole sequence of services that could complete the Mashup. Beyond pushing a vision for integrating the social dimension in the service composition process, this thesis has addressed a particular constraint for this recommendation system which conditions the interactive systems requirements in terms of response time. In this regard, we have developed robust algorithms adapted to the specificities of our problem. Whereas a composite service is considered as a sequence of basic service, finding similarities between users comes first to find frequent patterns (subsequences) and then represent them in an advantageous data structure for the recommendation algorithm. The proposed algorithm FESMA, provide exactly those requirements based on the FSTREE structure with interesting results compared to the prior art. Finally, to implement the proposed algorithms and methods, we have developed a Mashup creation framework, called Social Composer (SoCo). This framework, dedicated to end users, firstly implements abstraction and usability requirements through a workflow-based graphic environment. As well, it implements all the mechanisms needed to deploy composed service starting from an abstract description entered by the user. More importantly, SoCo has been augmented by including the dynamic recommendation functionality, demonstrating by the way the feasibility of this concept.

Full textAbstract:
Le paradigme de service dans les nouvelles technologies de l’information et de communication est omniprésent, si bien qu’on parle de science des services. Les services Web sont définis dans le cadre des architectures orientées services (SOA) qui permet de distinguer le fournisseur de service, le répertoire de services, et enfin le consommateur du service. Cette distinction permet de créer de nouveaux services en composant des services déjà existants. Cependant, la composition de services est principalement bénéfique aux utilisateurs expérimentés comme les développeurs de logiciels car elle requiert un niveau technique élevé. Par opposition, la tendance actuelle traduite par l’émergence du Web2.0, vise à permettre aux utilisateurs du Web de créer leurs propres services à travers les environnements de Mashup, ou de collaborer et de capitaliser des connaissances à travers les réseaux et les médias sociaux. Nous croyons qu’il existe un grand potentiel pour “démocratiser” la composition de services dans de tels contextes. L’émergence du Web 2.0, basé sur des paradigmes tels que le contenu généré par l’utilisateur (UGC, Mashups) et le web social, constitue, une opportunité intéressante pour améliorer la productivité de services par l’utilisateur final et accélérer son processus créatif en capitalisant les connaissances générées par tous les utilisateurs. Dans ce contexte, cette thèse vise à soutenir l'évolution du concept de composition de services par le biais de contributions significatives. La principale contribution de cette thèse est en effet l'introduction de la dimension sociale dans le processus de construction d'un service composite à travers les environnements dédiés aux utilisateurs finaux. Ce concept considère l'activité de composition de services (création d'un Mashup) comme une activité sociale. Cette activité révèle les liens sociaux entre les utilisateurs en fonction de leur similitude dans le choix et la combinaison des services. Ces liens permettent de diffuser d'expertise de composition de services. En d'autres termes, sur la base des schémas fréquents de composition, et la similitude entre les utilisateurs, lorsqu’un utilisateur est en train d’éditer un Mashup, des recommandations dynamiques lui sont proposées. Ces recommandations visent à compléter la première partie de Mashup déjà mis en place par l'utilisateur. Ce concept a été exploré à travers (i) la complétion de Mashup étape par étape en recommandant à chaque étape un service unique, et (ii) la complétion totale de Mashup en recommandant la séquence complète de services qui pourraient le compléter. Au-delà de l’introduction de la dimension sociale dans le processus de composition de services, cette thèse a adressé une contrainte particulière du système de recommandation liée aux exigences des systèmes interactifs en termes de temps de réponse. À cet égard, nous avons développé des algorithmes robustes et adaptées aux spécificités de notre problème. Alors qu’un service composite est considéré comme une séquence de service, la recherche de similarités entre les utilisateurs revient d'abord à trouver des modèles fréquents, puis de les représenter dans une structure de données avantageuse pour l'algorithme de recommandation. L’algorithme proposé FESMA répond à ces exigences en se basant sur la structure FSTREE et offrant des résultats intéressants par rapport à l'art antérieur. Enfin, pour mettre en œuvre les algorithmes et les méthodes proposées, nous avons développé un environnement de création de Mashup, appelé ‘Social Composer’ (SoCo). Cet environnement, dédié aux utilisateurs finaux, respecte les critères d'utilisation en se basant sur le workflow graphique. En outre, il met en œuvre tous les mécanismes nécessaires pour déployer le service composé à partir d'une description abstraite introduite par l'utilisateur. De plus, SoCo a été augmentée en y incluant la fonctionnalité de recommandation dynamique, démontrant la faisabilité de ce conceptService composition has risen from the need to make information systems more flexible and open.

In our thesis we use a preventive approach to stop privacy-invasive software (PIS) from entering the system. We aim at increasing the user awareness about the background activities of the software. These activities are implicitly written in End User License Agreement (EULA). We are using a multi-layer user notification approach to increase the user awareness and help him make a good decision, which is in accordance with the European legal framework. A proof of concept tool is developed that will use the user preferences to present the EULA in a compact and understandable form thereby helping the user in deciding with the installation of a software.

Full textAbstract:
The present thesis aims to deduce tasks and characteristics of end users during the open innovation process on the social web. The social web with its communities, forums and blogs affords new prospects as well as unknown challenges for companies, and at the same has increasingly influenced academic research during the last few years. Especially research regarding communication behaviour on the social web as well as social web technologies has currently progressed well. However, in innovation research, social web technologies are currently primarily used to integrate users into the company’s innovation process, for example through company user toolkits or company innovation communities. In those cases users were excluded from their normal social web environment and integrated into a company’s environment, a sort of laboratory environment. Despite this, the present research project will use the natural behaviour, comments and discussions of users within their social web environment to develop and apply a new mixed-method approach with the aim to deduce tasks and characteristics of innovative end users on the social web. To apply the mixed-method approach within a longitudinal case study and to deduce statements and regularities regarding the innovation process on the social web, it was possible to analyse the end user developer online forum of one of the leading open source CRM software technologies. Based on this analysis, the assumptions from an extensive literature analysis could be verified and extended: it could be shown that the expected single innovative user does not exist. In fact, the process from the initial idea to an innovation requires different users with different characteristics and different points of view. They will be deduced, explained and presented within the present thesis.

Full textAbstract:
[EN] Domain-specific languages (DSLs) are considered to be a powerful tool for enhancing the efficiency of software developers and bring software development closer to end-users from complex domains. However, the successful development of a DSL for a complex domain is a challenge from the technical point of view and because end-user acceptance is key.
Despite this fact, the relevant role of end-users during DSL development has traditionally been neglected. Normally, end-users participate at the beginning to communicate their preferences but they do not participate again until the DSL is completely implemented. As a consequence, if the language to develop reaches a complex domain, the chances that errors appear in the DSL are higher and solving them could involve large modifications that could have been avoided.
As a solution, in this PhD thesis, we propose an agile, model-driven method to involve end-users in DSL development. This thesis researches if the combination of best practices from the model-driven development (MDD) discipline and best practices from agile methods is a suitable approach to involve end-users in the DSL development process.
In order to validate the proposal, we have selected a highly complex domain such as the genetic analysis domain and we have collaborated with geneticists from three organizations. The proposed method has been used to involve these geneticists in the development of a DSL for the creation of genetic analysis pipelines. Simultaneously, we have carried out an empirical experiment to validate whether end-users and developers were satisfied with the proposal.[ES] Los lenguajes específicos de dominio (DSLs) son una herramienta muy potente para mejorar la eficiencia de los desarrolladores de software, así como para acercar el desarrollo software a usuarios sin conocimientos informáticos. Sin embargo, su principal problema es que desarrollar un DSL es complejo; no sólo desde el punto de vista técnico, sino especialmente porque la aceptación de dicho lenguaje por parte de los usuarios finales es clave. A pesar de este hecho, los métodos tradicionales de desarrollo de DSLs no enfatizan el importante rol de los usuarios finales durante el desarrollo. Normalmente, los usuarios participan al inicio para comunicar sus preferencias, pero no vuelven a participar hasta que el DSL está completamente desarrollado. Si el lenguaje a desarrollar aborda un dominio complejo, la posibilidad de que existan errores en el DSL es mayor, y su solución podría conllevar a modificaciones de gran calibre que podrían haberse evitado. Como solución, en esta tesis proponemos un método de desarrollo de DSLs, ágil, y dirigido por modelos que involucra a los usuarios finales. Esta tesis investiga si la combinación de buenas prácticas del desarrollo dirigido por modelos (MDD) y de buenas prácticas de métodos ágiles es adecuada para involucrar a los usuarios finales en el desarrollo de DSLs. Para validar la idoneidad de la propuesta, se ha seleccionado un dominio complejo como el de los análisis genéticos y se ha colaborado con un conjunto de genetistas procedentes de tres organizaciones. El método propuesto se ha utilizado para involucrar a dichos genetistas en el desarrollo de un DSL para la creación de pipelines para el análisis genético. Conjuntamente, se ha llevado a cabo un experimento empírico para validar si los usuarios finales y los desarrolladores están satisfechos con la propuesta de la presente tesis. En resumen, las contribuciones principales de esta tesis doctoral son el diseño e implementación de un método innovador, ágil y dirigido por modelos para involucrar a los usuarios finales en el desarrollo de DSLs, así como la validación de dicha propuesta en un entorno industrial en un desarrollo real de un DSL.

Normalment, els usuaris participen a l'inici per a comunicar les seues preferències, però no tornen a participar fins que el DSL està completament desenvolupat. Si el llenguatge a desenvolupar aborda un domini complex, la possibilitat de que hi hagen errors en el DSL es major i solucionar-los podria implicar modificacions de gran calibre que podrien haver-se evitat.

Full textAbstract:
The primary aims and objectives of this thesis are to identify the sources and operation of the errors which are introduced during end-user post-processing of airborne laser scanning data. Previous research has concentrated on the errors incorporated during data capture and preliminary supplier processing. The errors which are introduced by the end-users have been largely neglected. As a result, data users cannot currently estimate the errors within, and therefore the quality of, the models they produce. Laser scanning is a remote sensing technique for the capture of height data of the surface of the Earth. It offers competitive capture costs, high accuracy, and is particularly suited to capturing information in complex urban areas. As a result the commercial value of laser scanning data is high. However, in order to realise the potential of this technique, the quality of the datasets derived from the data must be assessed and the errors introduced during modelling understood. For users to make informed decisions regarding the design of their post-processing workflow it is fundamental that they know how and where errors may be introduced. The characteristics of these errors are investigated in this thesis using a range of approaches. End-user post-processing is divided into three techniques in the thesis: data structuring, filtering and segmentation. Each process is investigated hi terms of accuracy and sensitivity, through the comparison of several methods with reference models. New algorithms for filtering and segmenting laser data are presented. The errors created by each process are identified and analysed. The location of errors across the elevation surface are also investigated. It is shown how this information could be used to aid end-users design their post-processing methodology. The methodology for analyzing the errors is presented as a framework which could be used as a standard for ALS models. This thesis shows that the choice of post-processing methodology can significantly alter both the magnitude and spatial pattern of errors with a model derived from airborne laser scanning data. The differences between modeling strategies, and the importance of these differences, is shown with reference to a flood modeling application. Finally, strategies for minimizing error for post-processing are proposed.

Full textAbstract:
Behavior analysts have had much success in affecting behavior change with individuals diagnosed with intellectual disabilities as well as those who would be considered typically developing with a variety of intervention strategies; most of which involve affecting direct acting contingencies. However, the realm of language-based psychopathology has just begun to be addressed within the field through language based, or indirect acting strategies. Acceptance and Commitment Therapy (ACT) is based on the concept of derived stimulus relations and allows for a behavior analytic treatment of language-based psychopathology. The current study was intended to test the efficacy of a brief protocol-delivered ACT intervention with individuals who smoke marijuana. Oral swab drug screens were the primary dependent variable, along with the Acceptance and Action Questionnaire II (AAQ-II). All six ACT components were taught to each subject using a set list of metaphors and exercises and was assessed using a concurrent/non-concurrent multiple baseline across participants design. Results indicate that the brief protocol impacted levels of marijuana consumption with all three participants and that their self-reported levels of struggle (via the AAQ-II) lessened over the course of the training.

Full textAbstract:
The Casas Grandes Valley is located in the northwestern corner of the modern state of Chihuahua, Mexico. This area falls into the greater Northwest/Southwest cultural region. Research conducted on Casas Grandes ceramics up to this point has focused on form and design in connection with burials, authority, sociopolitical organization, ceremony and ritual, communication, and identifying cultural boundaries and influences. Very little has been said about some of the everyday uses of Casas Grandes ceramics. My thesis explores the evidences of use on ceramic vessels in the Casas Grandes region during the Medio period (AD 1200-1450). I conducted a use-alteration analysis on the interiors and exteriors of 300 vessels. The purpose of this study was to examine the question: how were the vessels used by the people of Casas Grandes? These analyses suggest that the vessels were typically used for separate but not altogether distinct use activities. All vessels had some evidences of wear, regardless of vessel form, size, or decoration. The general use patterns followed some intended functional categories, with enough variety to suggest vessels were also used according to individual needs.

Full textAbstract:
As new media grow, so do the users who navigate the virtual world. People and organizations are forced to adapt in order to stay relevant in a technologically driven marketplace. The sports world has been changed drastically because of new media. Athletes no longer communicate with the general public solely through traditional media outlets such as newspapers. Social networking sites such as Twitterallow athletes to directly communicate with mass audiences. This direct communication raises several questions with regard to dynamics of communication and uses of Internet portals. A content analysis examined professional athletes' "Twitter" posts to help answer these questions. While some of the hypotheses were not supported, results were telling. Topics among the sample of posts included direct communication with Twittermembers or links to videos and pictures, as well as "tweets" about each player's job. Findings suggested that professional athletes are mainly neutral overall when posting messages regarding their sport, team, peers, or fans. Limitations of the study and implications for future research are addressed.

Capillary electrophoresis is currently a very powerful technique for the analysis of seized drugs. A rapid analytical CE method for the screening and quantification of GHB and GBL was achieved using 300mM CTAC/25mM phosphate buffer pH 6.3. Reversed phase HPLC was achieved using 25mM phosphate buffer pH 6.5 and a Cl8 Aqua column. Chiral separation of 9 amphetamine type stimulants was obtained using a highly sulfated gamma-cyclodextrin as a chiral selector. MECC and CZE were compared for the analysis of psilocybin, while a rapid and robust method is presented for the analysis of major opium alkaloids, using dynamically coated capillary columns. The column is coated with a polycation followed by a polyanion coating, using a commercial reagent kit. Using a background electrolyte pH of 2.5 with the addition of hydroxypropyl-beta- cyclodextrin and dimethyl-beta-cyclodextrin, the analysis of morphine, papaverine, codeine, noscapine, and thebaine in opium samples was obtained with great resolution. Finally, separation of common benzodiazedpines was also investigated using CZE and a pH 2.5 phosphate buffer.

Full textAbstract:
Cette recherche se place dans le domaine de l’ingénierie industrielle, plus exactement aux premières étapes du processus d´innovation (Fuzzy Front-End). Aujourd´hui dans un monde globalisé, où la technologie est à la portée de tous, les entreprises cherchent de nouvelles techniques permettant de se distinguer de la concurrence, et offrent de nouveaux et meilleurs produits ou services ; une manière de conserver leurs avantages comparatifs ou d’en acquérir de nouveaux, pour des clients toujours plus exigeants, et dont les besoins changent constamment. Partant de ce constat, l’innovation se définit comme un processus long et continu, au sein duquel s’utilisent différents modèles. Du fait de la complexité du processus, il n’existe pas de modèle unique réunissant tous les besoins des clients. C’est pourquoi le processus d’innovation, implique différents acteurs de l’entreprise et de son environnement. Ces acteurs, dont l’importance varie, sont souvent d’origines diverses et possèdent des compétences variées. Ils ont des besoins différents, et sont soumis à des contraintes de travail différentes (ressources technologiques et financières, réglementations, etc...). Il paraît ainsi essentiel pour l’entreprise de créer un modèle unique, capable d’identifier les besoins de toutes les parties prenantes, avant d’entamer le processus de développement de nouveaux produits. C’est pour l’entreprise une manière de renforcer le processus d’innovation, et de réduire le taux d´échec lors du lancement de nouveaux produits. Ainsi l’objectif de cette étude est de proposer une nouvelle méthode d’analyse des impacts de l’innovation (A.I), afin de permettre aux entreprises d’identifier les besoins dynamiques des acteurs. Celles-ci pourront ainsi mieux définir leurs nouveaux produits et s’adapter plus facilement aux évolutions du marché. Cet outil fait partie d´une méthodologie de gestion des projets innovants, et doit être utilisé avant la définition des caractéristiques fonctionnelles du nouveau produit. Ceci nous ramène aux premières phases du développement, avant la conception du produit, qui comprennent toutes les étapes depuis la définition des besoins et opportunités pour l´innovation, jusqu’à la prise de décision pour le développement du nouveau produit, appelée Fuzzy Front-End. L’apport théorique de notre travail : Il n´existe pas de définition des impacts de l’innovation (I_n), nous avons donc fait un travail bibliographique sur le concept d’impact. Celui-ci a permis d’explorer les différentes définitions d´impact au sein de différentes disciplines (ingénierie, écologie, psychologie, etc.). Nous avons proposé de cette manière, notre propre définition de l’impact adaptée au contexte de l´innovation. Cette recherche bibliographique, nous a aussi permis d’identifier les différents types d´impacts et de justifier l´utilisation de différentes méthodologies. La contribution méthodologique : l’approche proposée pour l´analyse des impacts de l´innovation (A.I) se décompose en deux étapes. La première vise à modéliser l’« écosystème d´innovation », sur la base des relations, de l´importance et des besoins individuels de chacun des acteurs face au nouveau produit. Ceci grâce à une Analyse des Besoins Dynamiques (A.B.D), qui permettra d´obtenir les besoins agrégés permettant de représenter le système complet, sans considérer les possibles perturbations du milieu extérieur ou les impacts de la même innovation. Pour bien identifier et décrire les besoins des acteurs, nous avons basé la méthodologie sur l´observation de leurs activités. Ainsi, nous avons pu identifier les différents besoins des acteurs de l´innovation sur la base de l’analyse RAR (Ressources, Activités, Résultat), ensuite nous avons classifié les besoins grâce au modèle de KANO et ses améliorations réalisées par Tontini. Une méthode originale d’agrégation des besoins de tous les acteurs est proposée.[...]This research belongs to the industrial engineering field, focusing on the first stages of the innovation process (Fuzzy Front-End). In a globalized world, where the technology is near to everyone, enterprises are looking for new technologies to be different from their competitors, offering new and better products / services as a strategy to keep or acquire new competitive advantages. Moreover, innovation is a large and continuous process, where different management models are used. But, because of the complexity of the process, no general model is suitable for situations and projects. Thus, the innovation process involves different stakeholders from the company and its environment. These individuals come from different origins (field of knowledge), have different needs, abilities, importance and work under different restrictions (technological or financial resources, work rules, etc.). Consequently, it is essential for the enterprise to identify all the needs of the parts involved in the products. And, a model is required in order to identify the stakeholder’s needs before starting design tasks. This model aims at more robustness in the new product development process and at the reduction of the failure rate when launching new products. Thus, the objective of this PhD thesis is to propose a new method to analyze the impact of the innovation, allowing companies to identify the dynamic actors' needs, to improve the definition of their new products and to adapt to the possible changes of the market. This tool is part of an innovative projects management methodology, used before the elaboration of the functional specifications of a new product. This locates the research in the first stages of development called Fuzzy Front-End: before the genesis of the product. Fuzzy front ends integrate among others the opportunity / needs identification for innovation to the development of the new product decision taking. The proposed approach for the innovation impact analysis (A.I) consists of two stages: the first one intends to model an innovation ecosystem, integrating the relations, the importance of each stakeholder and their individual necessities in regard to the new product. Through a Dynamic Needs Analysis (A.B.D) it will be possible to get the global needs, which represent the whole system, without considering the disturbances of the environment or the impact of the same innovation. Thus, the second stage of the model, through the generation of innovation impact scenarios (S.I.I), evaluates the impact of the innovation the new product may face at its market launching. Due to a new product emergence changes emerge: actors’ performance, their interrelations, the importance and their own needs about the product [...]

Urbanization has taken a major toll on the water quality of Lake Tarpon. In response, there have been management strategies and legislation put in place to help improve water quality. Our objective was to identify what management strategies and other environmental factors were driving changes in Lake Tarpons water quality from 1970 - 2010. Trends in water quality were analyzed against precipitation, land use and water quality management strategies to achieve this. Results found that two water quality management strategies, the creation of the Lake Tarpon Outfall Canal and the closing of the Lake Tarpon Sink, improved water quality the most. Other management strategies that undoubtedly helped improve water quality but were not able to be quantified were regulations that have made growth more sustainable (FAC 62 - 25, FAC 10D-6) and management strategies such as converting septic to sewer and lake level fluctuation.

This study seeks to understand and document how people recovering from opioid addiction communicate about health and identity in the context of a methadone clinic. This project emerges in response to the rising incidence of opioid addiction and overdose death in the U.S. and suggests there is an urgent theoretical and practical calling for bringing forth the stories of people experiencing addiction and recovery. Guided by the structure-centered approach (SCA) to health communication, this study employs a thematic narrative analysis through interviews with 4 methadone maintenance treatment (MMT) patients about the meanings of health, recovery, and identity. With respect to how methadone patients communicate about health and identity, study findings reveal three key themes, which I distinguish as: 1) health as normalcy; 2) health as lack of resources; and 3) recovering the self, (be)longing, and health citizenship. It is through an understanding of these themes that this project contributes, in several meaningful ways, to research and praxis on health communication in addiction treatment spaces. Limitations of research design and considerations for future research projects on health and addiction are provided.

Full textAbstract:
The Utah Department of Transportation (UDOT) Traffic and Safety Division continues to advance the safety of roadway sections throughout the state. In an effort to aid UDOT in meeting their goal, the Department of Civil and Environmental Engineering at Brigham Young University (BYU) has worked with the Statistics Department in developing analysis tools for safety. The most recent of these tools has been the development of a hierarchical Bayesian Poisson Mixture Model (PMM) of traffic crashes known as the Utah Crash Prediction Model (UCPM), a hierarchical Bayesian Binomial statistical model known as the Utah Crash Severity Model (UCSM), and a Bayesian Horseshoe selection method. The UCPM and UCSM models helped with the analysis of safety on UDOT roadways statewide and the integration of the results of these models was applied to Geographic Information System (GIS) framework. This research focuses on the addition of roadway attributes in the selection and analysis of “hot spots.” This is in conjunction with the framework for highway safety mitigation migration in Utah with its six primary steps: network screening, diagnosis, countermeasure selection, economic appraisal, project prioritization, and effectiveness evaluation. The addition of roadway attributes was included as part of the network screening, diagnosis, and countermeasure selection, which are included in the methodology titled “Hot Spot Identification and Analysis.” Included in this research was the documentation of the steps and process for data preparation and model use for the step of network screening and the creation of one of the report forms for the steps of diagnosis and countermeasure selection. The addition of roadway attributes is required at numerous points in the process. Methods were developed to locate and evaluate the usefulness of available data. Procedures and systemization were created to convert raw data into new roadway attributes, such as grade and sag/crest curve location. For the roadway attributes to be useful in selection and analysis, methods were developed to combine and associate the attributes to crashes on problem segments and problem spots. The methodology for “Hot Spot Identification and Analysis” was enhanced to include steps for the inclusion and defining of the roadway attributes. These methods and procedures were used to help in the identification of safety hot spots so that they can be analyzed and countermeasures selected. Examples of how the methods are to function are given with sites from Utah’s state roadway network.

Full textAbstract:
This study analyzes the use of social media by state legislative bodies, broken down by a combination of legislative body (House, Senate, or general legislature) and by party (Republican or Democrat). I analyzed Twitter and Facebook posts for each of these groups during the week of January 11-15, 2016, specifically looking for four improvements: transparency, policy making, public services, and knowledge management and cross-agency cooperation. The research questions are: RQ1: Which social media platforms are state legislatures using? RQ2: What improvements are the state legislatures using in their social media output? RQ3: Is there a significant difference in the improvements presented on Facebook and Twitter? The results revealed that 52.9% of 700 groups had created Twitter and Facebook accounts, with 55% of those accounts on Twitter. The analysis also showed that upcoming events are more common than expected on Twitter, and that posts asking for support on an issue are more common than expected on Facebook. This study is important because it relates to voting trends of the 18-24 age group in the United States. An overwhelming majority of this age group uses social media, but this group has very low voting rates. If governmental bodies can utilize social media to communicate with this population, then it is possible that they would be better informed and more motivated to vote and be civically engaged.

Full textAbstract:
Bibliography: pages [83]-89.One of the basic needs of both information systems practitioners and academics is in determining what skills and knowledge staff need in order to be able to perform adequately in their jobs (Nelson : 1991). This study was concerned with the information technology and information systems learning needs of two distinct classes of personnel; end users and information systems personnel. More specifically, it examines the perceptions that each group has of the other's particular deficiencies. It also compares the importance that each group accords to skill or knowledge in particular items for their counterparts, and how these expectations match their counterparts' own perceptions of item importance. The study was thus concerned with cross-perceptions; the perceptions that each group has of the other. This study examined these perceptions by means of the analytical survey method. The research instrument used was an adapted version of an instrument previously validated and used by Nelson (1991). The research instrument was completed by 168 employees within ten different organizations. The findings suggest that within six different areas of knowledge and skill both end user and IS personnel perceived their counterparts to be most deficient in the area of general IS knowledge; particularly in knowledge of the fit between IS and the organization, the potential uses of IS/IT within the organization, and in the use of IS for competitive advantage. In addition, both groups of personnel perceived their counterparts to be particularly deficient ii') their ability to communicate effectively. The deficiency in general IS knowledge was aggravated by the finding that both groups expect their counterparts to carry more of the responsibility for knowledge in general IS matters than their counterparts appear willing to assume. The implication of this mismatch of expectations is that it must first be resolved by clarifying the respective roles and responsibilities of both end user and IS personnel before the deficiencies themselves can be dealt with.

Vakharia, Sheila P. "The Influence of Gender on Perceived Treatment Need among a Community Sample of Substance Users." FIU Digital Commons, 2013. http://digitalcommons.fiu.edu/etd/925.
Full textAbstract:
Purpose: Most individuals do not perceive a need for substance use treatment despite meeting diagnostic criteria for substance use disorders and they are least likely to pursue treatment voluntarily. There are also those who perceive a need for treatment and yet do not pursue it. This study aimed to understand which factors increase the likelihood of perceiving a need for treatment for individuals who meet diagnostic criteria for substance use disorders in the hopes to better assist with more targeted efforts for gender-specific treatment recruitment and retention. Using Andersen and Newman’s (1973/2005) model of individual determinants of healthcare utilization, the central hypothesis of the study was that gender moderates the relationship between substance use problem severity and perceived treatment need, so that women with increasing problems due to their use of substances are more likely than men to perceive a need for treatment. Additional predisposing and enabling factors from Andersen and Newman’s (1973/2005) model were included in the study to understand their impact on perceived need. Method: The study was a secondary data analysis of the 2010 National Survey on Drug Use and Health (NSDUH) using logistic regression. The weighted sample consisted of a total 20,077,235 American household residents (The unweighted sample was 5,484 participants). Results of the logistic regression were verified using Relogit software for rare events logistic regression due to the rare event of perceived treatment need (King & Zeng, 2001a; 2001b). Results: The moderating effect of female gender was not found. Conversely, men were significantly more likely than women to perceive a need for treatment as substance use problem severity increased. The study also found that a number of factors such as race, ethnicity, socioeconomic status, age, marital status, education, co-occurring mental health disorders, and prior treatment history differently impacted the likelihood of perceiving a need for treatment among men and women. Conclusion: Perceived treatment need among individuals who meet criteria for substance use disorders is rare, but identifying factors associated with an increased likelihood of perceiving need for treatment can help the development of gender-appropriate outreach and recruitment for social work treatment, and public health messages.

Full textAbstract:
In this dissertation, I will review the history and general strategies for performing kinetic proteomics. I will then demonstrate that I have published an open source, user-friendly program for other scientists to use to perform kinetic proteomics data analysis, as well as publishing a novel discovery of key ribosomal subunits being replaced within the lifetime of the ribosome, which was discovered through use of kinetic proteomics. Finally, I will discuss work that is ongoing to improve my software tool for use in human subjects, and work being done to combine kinetic proteomics with other global analysis methods to make novel biological discoveries. Proteins are constantly synthesized and destroyed to ensure sufficient functioning proteins to meet cellular needs, a process called protein turnover. Synthesis and degradation are carefully balanced over time to ensure that average protein concentrations do not change drastically. The status quo of the cell, or protein homeostasis, is required for the health of the organism. If protein homeostasis breaks down, serious diseases, such as Alzheimer<'>s, can result when proteins aggregate instead of being degraded properly. Because protein turnover is the means to maintain protein homeostasis while keeping sufficient functioning proteins, measuring protein turnover is critical to understanding biological processes and disease states. Measuring protein turnover rates on a broad scale is possible using a method called kinetic proteomics, and the improvement of kinetic proteomics is where I have focused the work for this dissertation.

Marfan Syndrome leads to the weakening of the thoracic aorta and ultimate rupture causing death of the patient. Current monitoring method involves measuring the diameter of the aorta near the heart. Our approach is to develop a new technology that will provide clinicians the ability to evaluate the size, shape and motion of the entire thoracic aorta using four-dimensional cardiac MRI. This project alters the existing research algorithms to provides an integrated application for processing the images and provides novel measurements about the aorta from a data set of 32 normal subjects and 38 patients with serial scans.

Full textAbstract:
Traditional measurements of phytoplankton N uptake have been confounded by bacterial retention on filters used in 15N uptake studies, and such methodological obstacles have limited our understanding of phytoplankton-bacterial interactions regarding N cycling. In this research, uptake of various inorganic and organic N substrates by phytoplankton and bacteria was measured in several marine ecosystems using two distinct approaches: size fractionation into phytoplankton and bacterial size classes, and flow cytometric (FCM) sorting of autotrophic cells. Comprehensive assessments of N uptake dynamics were conducted in Chesapeake Bay, the Mid-Atlantic Bight, and Raunefjord, Norway, with supplementary data collected from the York River, Virginia and the Gulf of Mexico. In Chesapeake Bay, the composition of the dissolved N pool shifted from being dominated by dissolved inorganic N (DIN) in the upper bay to mostly dissolved organic N (DON) in the lower bay. Accordingly, phytoplankton nitrate uptake was highest near the head, whereas uptake of urea and dissolved free amino acids generally increased southward. Nonetheless, ammonium was the dominant form of N used by phytoplankton and bacteria throughout the bay. In the Mid-Atlantic Bight, the surface layer was devoid of DIN but ambient urea concentrations were relatively high and this organic substrate supported a large majority of total measured N uptake. The dissolved N pool in the bottom water consisted of about two-thirds DIN, with ammonium contributing most to total uptake. Bacteria were especially active in the bottom water and contributed over half of the total DIN uptake, and there was evidence of bacterial urea uptake in the surface water. In Raunefjord, a mesocosm approach was used to examine N uptake by a bloom of colonial Phaeocystis as well as the competition between phytoplankton and bacteria for limited N resources. Despite amending with nitrate, ammonium was the primary N form supporting the bloom. In the unfertilized mesocosm, bacteria were responsible for about half the urea uptake, most of the DFAA uptake, and at least a third of DIN uptake. Overall, total dissolved N concentrations and total N uptake decreased from estuarine to oceanic waters, although uptake rates were highly variable within each ecosystem. The reduced N forms, ammonium and urea, were most important to phytoplankton N nutrition, and contrary to traditional belief, urea at times played an important role in bacterial N uptake. With respect to methodological approaches, traditional filtration resulted in significant overestimation of phytoplankton N uptake due to the inclusion of, and 15N enrichment in, bacterial biomass retained on filters. This research represents the first comprehensive assessment of phytoplankton-specific N uptake across various ecosystems. It highlights not only the need for careful qualification of uptake rates measured using traditional approaches, but also the potential application of FCM sorting to more detailed examination of N uptake by phytoplankton in general, but also by specific taxa in various marine ecosystems.

Full textAbstract:
The term “home range” refers to the area in which an animal spends most of its time during everyday activities. This study examined the effects of four different home range estimation techniques on the proportions of habitats located therein. The study utilized a point dataset collected for twenty individual Florida Black Bears (Ursus americanus floridanus), occurring in five different areas throughout the state of Florida. Each dataset was used to create home ranges using the following techniques: (1) Minimum Convex Polygon, (2) Kernel Density Estimation, (3) Characteristic Hull Polygon, and (4) Time-Geographic Density Estimation, a new home range estimator which has not been thoroughly tested prior to this study. A dataset of land cover types was clipped with each home range and the areas of habitats were recalculated. The proportion of each land cover type was evaluated and the results compared first within each dataset, then between all datasets used. Repeated measures analysis of variance (ANOVA) was used to determine whether the four home range estimation techniques produced significantly different areas and proportions of each habitat type. These results were then evaluated to determine whether the method of home range estimation has an effect on which land cover types are most utilized by a species and, therefore, which habitats are considered preferable. While the choice of home range estimation did not have an effect on which habitats were determined to be most frequently visited, it did affect the amount of each habitat found within each home range. Furthermore, there was a statistically significant change in the amount of developed areas, specifically between the characteristic hull polygon and kernel density estimation methods. These results suggest the choice of home range estimator affects habitat analysis and that researchers should use the method best suited for the dataset.
