The decision to patronize a particular store usually starts with a set of characteristics or attributes that consumers consider important. Consumers then use these attributes to make decisions regarding what store or stores can cater to their particular needs. Past retail and marketing studies have identified several consumer-oriented store attributes such as price, quality, variety, discounts, store reputation and their relationship to store patronage, but these studies overlooked how the physical environment affects retail store patronage. In addition, very few studies have addressed the issue of shopping scenarios and how they affect store patronage. The purpose of this study was to examine the influence of selected environmental dimensions on store patronage using specific apparel shopping scenarios. Data were collected using a random sample of women age 18 and over throughout the United States. The final sample consisted of 151 women. Four hypotheses were formulated and tested using factor analysis, cluster analysis, MANOVA, and Chi-square. The hypotheses tested for differences in (a) importance of environmental dimensions relative to three shopping scenarios, (b) importance of environmental dimensions relative to shopping orientations, (c) perceptions of first store choice relative to shopping orientations, and (d) attitude toward first store choice. Results revealed no difference in importance ratings of two environmental dimension factors, Sensory/Layout (Factor 1) and Music/Aesthetics (Factor 2), for three shopping scenarios (i.e., a dress for a formal social gathering, family gathering, work or community activity). Significant differences were found in the importance ratings of the Sensory/Layout and Music Aesthetics dimension factors across shopping orientation clusters. The clusters were named Decisive Apparel Shoppers (Cluster 1), Confident Apparel Shoppers (Cluster 2), Bargain Apparel Shoppers (Cluster 3), and Appearance Conscious Apparel Shoppers. The Bargain Apparel Shoppers had higher mean scores on the environmental factors than the other shopper groups. With regard to first store choice, the department store was chosen most often as first store choice. Furthermore, differences were found in perception of the environment for first store choice across the shopping orientation clusters. No differences were found for the Ventilation/Sensory factor; however, differences were found for the Signs perception factor. Respondents expressed relatively unfavorable attitudes toward their first store choice. However, of those that expressed an unfavorable attitude, several respondents indicated they were likely to visit their first store choice again. / Ph. D.

This master’s thesis aims to contribute to the design and innovation management literature by exploring to understand an alternative shared social kitchen that is people-driven around shared interests, promoting social well-being. This is in order to explore the potential of systemic, regenerative, speculative sustainable design in addressing challenges faced by shared kitchens, while understanding diverse user needs within enabling contexts. Through a design process of ethnography research, frameworks, imperatives and solution finding, the kitchen was explored from different participants’ perspectives and context. The resulting scenario from the ethnography research highlighted technology, food waste, circularity and food system scenarios. The study contributes to future dialogue and understanding of the different processes and perspectives in imaginative shared kitchen using an explorative approach. It is vital to understand the holistic picture of the shared kitchen and not only focus on the functional, environmental and economic aspect, but also on the social development for a more inclusive design.

Sua atuação baseia-se principalmente no desenvolvimento de projetos e na busca de conciliar o raciocínio objetivo da indústria com o pensamento subjetivo da criação. A complexidade de encontrar o equilíbrio entre estas esferas em um ambiente dinâmico e caracterizado por incertezas configura-se como um desafio para o setor e transparece no seu processo decisório. O presente estudo parte do pressuposto que a indústria audiovisual poderia aprimorar seus processos de projeto se as tomadas de decisões estratégicas fossem apoiadas por instrumentos capazes de conjugar estas visões distintas. O design é um campo que está familiarizado em articular o conhecimento e a criatividade com o propósito de gerar aprendizagem, realizar escolhas e resolver problemas. Dentre os recursos estratégicos que o design utiliza para trabalhar com aspectos divergentes, a construção de cenários apresenta-se como um exercício capaz lidar com múltiplas perspectivas, auxiliar a tomada de decisão e consequentemente aprimorar o processo de projeto. Nesse sentido, o objetivo geral desta pesquisa é compreender como a construção de cenários contribui para a tomada de decisão estratégica no âmbito audiovisual. Para tanto, realizou-se entrevistas com experts do setor audiovisual e foi utilizada a análise de protocolo para explorar a construção dos cenários com a técnica think aloud. Como principais resultados, percebeu-se que os cenários de design atuam como uma ponte estratégica capaz de propiciar a compreensão de conceitos diferentes, esclarecer ideias e negociar critérios. A conversa estimulada pelo exercício promove além da geração de novos conhecimentos a aproximação entre os envolvidos, a qual produz uma sensação de segurança e confiança que são aspectos valorizados na tomada de decisão no audiovisual. Para que sejam alcançados os resultados considerados característicos dos cenários como a amplitude do modelo mental e o deslocamento de antigas visões, a pesquisa indicou que é fundamental que as propriedades da prática sejam bem exploradas e que, em especial, o fator “tempo” seja considerado como uma condição chave para a realização do exercício. Além disso, estudo propõe um modelo conceitual que sintetiza de que maneira a construção de cenários de design pode contribuir com a tomada de decisão estratégica do audiovisual e, eventualmente, contribuir com outras áreas do saber, enriquecendo os conhecimentos sobre este tema. / The audiovisual industry is part of the set of sectors that makes up the creative economy. Its performance is based mainly on the development of projects and steadfast search to reconcile the industry objective reasoning with creation subjective thought. The complexity of finding the balance between these spheres in a dynamic environment characterized by uncertainties is a challenge for the industry and is evident in its strategic decision-making process. This study assumes that the audiovisual industry could improve its project procedures if strategic decision-making were supported by instruments capable of combining these different visions. Design is used to articulate knowledge and creativity (taken in this research as objective and subjective thinking), with the purpose of learning process, making choices and solving problems. Among the strategic resources that design uses to deal with divergent aspects, the construction of scenarios is a practice able to handle with multiple perspectives, helping decision making and eventually improving the project process. Thus, this research general aim is to understand how building different scenarios up may help to the strategic decision making in the audiovisual industry. For this purpose, experts from the audiovisual sector were interviewed and protocol analysis was evaluated to explore the construction of scenarios using the think aloud technique. As main results, it was noticed that designing scenarios have effect on providing knowledge of different concepts as well as clarifying ideas and negotiating criteria. Practice stimulated changing impressions and promotes not only the generation of new knowledge, but also the approach between the involved, which produces security and confidence that are important aspects in the decision making process in the audiovisual. In order to achieve the results considered characteristic of building the scenarios up, for instance the mental model amplitude and old visions displacement, the research demonstrated that it is fundamental that the properties of the practice should be well explored and, especially, time must be considered as a key condition for performing the exercise. In addition, the study proposes a conceptual model that synthesizes how the construction of design scenarios can contribute to the strategic decision making of the audiovisual sector and, possibly, contribute with other areas of knowledge, enriching the knowledge on this theme.

Die vorliegende Arbeit 'Abflu&szlig;entwicklung in Teileinzugsgebieten des Rheins - Simulationen f&uuml;r den Ist-Zustand und f&uuml;r Klimaszenarien' untersucht Auswirkungen m&ouml;glicher zuk&uuml;nftiger Klima&auml;nderungen auf das Abflu&szlig;geschehen in ausgew&auml;hlten, durch Mittelgebirge gepr&auml;gten Teileinzugsgebieten des Rheins: Mosel (bis Pegel Cochem); Sieg (bis Pegel Menden 1) und Main (bis Pegel Kemmern).<br><br>In einem ersten Schritt werden unter Verwendung des hydrologischen Modells HBV-D wichtige Modellprozesse entsprechend der Einzugsgebietscharakteristik parametrisiert und ein Abbild der Gebietshydrologie erzeugt, das mit Zeitreihen gemessener Tageswerte (Temperatur, Niederschlag) eine Zeitreihe der Pegeldurchfl&uuml;sse simulieren kann. Die G&uuml;te der Simulation des Ist-Zustandes (Standard-Me&szlig;zeitraum 1.1.1961-31.12.1999) ist f&uuml;r die Kalibrierungs- und Validierungszeitr&auml;ume in allen Untersuchungsgebieten gut bis sehr gut.<br>Zur Erleichterung der umfangreichen, zeitaufwendigen einzugsgebietsbezogenen Datenaufbereitung f&uuml;r das hydrologische Modell HBV-D wurde eine Arbeitsumgebung auf Basis von Programmerweiterungen des Geoinformationssystems ArcView und zus&auml;tzlichen Hilfsprogrammen entwickelt. Die Arbeitsumgebung HBV-Params enth&auml;lt eine graphische Benutzeroberfl&auml;che und r&auml;umt sowohl erfahrenen Hydrologen als auch hydrologisch geschulten Anwendern, z.B. Studenten der Vertiefungsrichtung Hydrologie, Flexibilit&auml;t und vollst&auml;ndige Kontrolle bei der Ableitung von Parameterwerten und der Editierung von Parameter- und Steuerdateien ein. Somit ist HBV-D im Gegensatz zu Vorl&auml;uferversionen mit rudiment&auml;ren Arbeitsumgebungen auch au&szlig;erhalb der Forschung f&uuml;r Lehr- und &Uuml;bungszwecke einsetzbar.<br><br>In einem zweiten Schritt werden Gebietsniederschlagssummen, Gebietstemperaturen und simulierte Mittelwerte des Durchflusses (MQ) des Ist-Zustandes mit den Zust&auml;nden zweier Klimaszenarien f&uuml;r den Szenarienzeitraum 100 Jahre sp&auml;ter (2061-2099) verglichen. Die Klimaszenarien beruhen auf simulierten Zirkulationsmustern je eines Modellaufes zweier Globaler Zirkulationsmodelle (GCM), die mit einem statistischen Regionalisierungsverfahren in Tageswertszenarien (Temperatur, Niederschlag) an Me&szlig;stationen in den Untersuchungsgebieten &uuml;berf&uuml;hrt wurden und als Eingangsdaten des hydrologischen Modells verwendet werden.<br>F&uuml;r die zweite H&auml;lfte des 21. Jahrhunderts weisen beide regionalisierten Klimaszenarien eine Zunahme der Jahresmittel der Gebietstemperatur sowie eine Zunahme der Jahressummen der Gebietsniederschl&auml;ge auf, die mit einer hohen Variabilit&auml;t einhergeht. Eine Betrachtung der saisonalen (monatlichen) &Auml;nderungsbetr&auml;ge von Temperatur, Niederschlag und mittlerem Durchflu&szlig; zwischen Szenarienzeitraum (2061-2099) und Ist-Zustand ergibt in allen Untersuchungsgebieten eine Temperaturzunahme (h&ouml;her im Sommer als im Winter) und eine generelle Zunahme der Niederschlagssummen (mit starken Schwankungen zwischen den Einzelmonaten), die bei der hydrologischen Simulation zu deutlich h&ouml;heren mittleren Durchfl&uuml;ssen von November bis M&auml;rz und leicht erh&ouml;hten mittleren Durchfl&uuml;ssen in den restlichen Monaten f&uuml;hren. Die St&auml;rke der Durchflu&szlig;erh&ouml;hung ist nach den individuellen Klimaszenarien unterschiedlich und im Sommer- bzw. Winterhalbjahr gegenl&auml;ufig ausgepr&auml;gt. Hauptursache f&uuml;r die simulierte starke Zunahme der mittleren Durchfl&uuml;sse im Winterhalbjahr ist die trotz Temperaturerh&ouml;hung der Klimaszenarien winterlich niedrige Evapotranspiration, so da&szlig; erh&ouml;hte Niederschl&auml;ge direkt in erh&ouml;hten Durchflu&szlig; transformiert werden k&ouml;nnen.<br>Der Vergleich der Untersuchungsgebiete zeigt in Einzelmonaten von West nach Ost abnehmende &Auml;nderungsbetr&auml;ge der Niederschlagssummen, die als Hinweis auf die Bedeutung der Kontinentalit&auml;tseinfl&uuml;sse auch unter ge&auml;nderten klimatischen Bedingungen in S&uuml;dwestdeutschland aufgefa&szlig;t werden k&ouml;nnten.<br>Aus den regionalisierten Klimaszenarien werden &Auml;nderungsbetr&auml;ge f&uuml;r die Modulation gemessener Zeitreihen mittels synthetischer Szenarien abgeleitet, die mit einem geringen Rechenaufwand in hydrologische Modellantworten &uuml;berf&uuml;hrt werden k&ouml;nnen. Die direkte Ableitung synthetischer Szenarien aus GCM-Ergebniswerten (bodennahe Temperatur und Gesamtniederschlag) an einzelnen GCM-Gitterpunkten erbrachte unbefriedigende Ergebnisse.<br>Ob, in welcher H&ouml;he und zeitlichen Verteilung die in den (synthetischen) Szenarien verwendeten Niederschlags- und Temperatur&auml;nderungen eintreten werden, kann nur die Zukunft zeigen. Eine Absch&auml;tzung, wie sich die Abflu&szlig;verh&auml;ltnisse und insbesondere die mittleren Durchfl&uuml;sse der Untersuchungsgebiete bei m&ouml;glichen &Auml;nderungen entwickeln w&uuml;rden, kann jedoch heute schon vorgenommen werden. <br><br>Simulationen auf Szenariogrundlagen sind ein Weg, unbekannte zuk&uuml;nftige Randbedingungen sowie regionale Auswirkungen m&ouml;glicher &Auml;nderungen des Klimasystems ausschnittsweise abzusch&auml;tzen und entsprechende Risikominderungsstrategien zu entwickeln. Jegliche Modellierung und Simulation nat&uuml;rlicher Systeme ist jedoch mit betr&auml;chtlichen Unsicherheiten verkn&uuml;pft. Vergleichsweise gro&szlig;e Unsicherheiten sind mit der zuk&uuml;nftigen Entwicklung des sozio&ouml;konomischen Systems und der Komplexit&auml;t des Klimasystems verbunden. Weiterhin haben Unsicherheiten der einzelnen Modellbausteine der Modellkette Emissionsszenarien/Gaszyklusmodelle - Globale Zirkulationsmodelle/Regionalisierung - hydrologisches Modell, die eine Kaskade der Unsicherheiten ergeben, neben Datenunsicherheiten bei der Erfassung hydrometeorologischer Me&szlig;gr&ouml;&szlig;en einen erheblichen Einflu&szlig; auf die Vertrauensw&uuml;rdigkeit der Simulationsergebnisse, die als ein dargestellter Wert eines Ergebnisbandes zu interpretieren sind.<br><br>Der Einsatz <br>(1) robuster hydrologischer Modelle, die insbesondere temperaturbeeinflu&szlig;te Prozesse ad&auml;quat beschreiben,<br>(2) die Verwendung langer Zeitreihen (wenigsten 30 Jahre) von Me&szlig;werten und<br>(3) die gleichzeitige vergleichende Betrachtung von Klimaszenarien, die auf unterschiedlichen GCMs beruhen (und wenn m&ouml;glich, verschiedene Emissionsszenarien ber&uuml;cksichtigen),<br>sollte aus Gr&uuml;nden der wissenschaftlichen Sorgfalt, aber auch der besseren Vergleichbarkeit der Ergebnisse von Regionalstudien im noch jungen Forschungsfeld der Klimafolgenforschung beachtet werden. / This thesis 'Development of runoff in subcatchments of the River Rhine - simulations of the current state and for climate change scenarios' investigates the impacts of possible future climate changes on runoff and runoff regime in selected subcatchments of the River Rhine. The regional climate in the selected subcatchments Mosel (up to gauge Cochem), Sieg (gauge Menden 1) and Main (gauge Kemmern) is affected by the middle mountain ranges.<br><br>In a first step, important model processes are parameterized according to catchment characteristics. A representation of the regional hydrology is then produced by using the hydrological model HBV-D. Based on time series of daily measurements (temperature, precipitation) at stations within the catchment, this representation can be used to realistically simulate time series of runoff and discharge. <br>In all examined areas, the quality of simulations of the calibration and validation periods for the current state (standard period of measurements 01/01/1961-12/31/1999) can be regarded as good to excellent. <br>To aid the catchment-specific, extensive and time-consuming data processing, a working environment for the hydrological model HBV-D has been developed. It is based on program extensions of the geographical information system ArcView and further programs. The working environment HBV-Params contains a graphical interface that gives both experienced hydrologists and students full control and enables them to flexibly derive parameter values and edit parameter and control files. In contrast to previous versions with only rudimentary working environments, HBV-D can therefore be utilized for research as well as for educational purposes. <br><br>In a second step, the current states of areal precipitation, areal temperature and simulated mean discharge (MQ) are compared to the corresponding states for two scenarios of future climate changes (100 years later, 2061-2099). These scenarios are based on simulated global circulations of one model run for each of two global circulation models (GCM). These global circulations are regionalized (downscaled) using a statistical approach into scenario time series of daily values (temperature, precipitation - input for the hydrological model) at control stations within the individual catchments. <br>For the second half of the 21st century, both regionalized climate change scenarios indicate increases in the mean annual areal temperature and mean annual sum of precipitation, along with a high variability of the latter. The seasonal (monthly) changes in temperature, precipitation and mean discharge between scenario state (2061-2099) and current state indicate increases in temperature (higher in summer than in winter) as well as a general increase in precipitation sums (strong fluctuations between individual months). In the hydrological simulations for all investigated catchments, this results in considerably higher mean discharges from November to March and small increases in mean discharge for the other months. The magnitude of the increases in discharge depends on the individual climate change scenario, one showing higher increases than the other during the summer half-year and vice versa for the winter half-year. The main reason for the simulated strong increase in mean discharge during winter half-year is, in spite of higher temperatures, the still relatively low evapotranspiration which allows higher precipitation to be directly transformed into higher discharges. <br>The comparison of the investigated catchments shows decreasing amounts of changes in the sum of precipitation from West to East in individual months. This indicates the importance of continentality under changed climatic conditions in Southwest Germany. <br>For the modification of measured time series (temperature, precipitation), which can be easily converted as synthetic scenarios into simulated hydrological results, amounts of change are derived from regionalized (downscaled) climate change scenarios. The derivation of synthetic scenarios directly from GCM output at individual GCM gridpoints yielded unsatisfactory results. <br>Only the future itself can show whether the timing and amount of changes in temperature and precipitation used in (synthetic) climate change scenarios come close to reality. An assessment of possible developments in runoff regime and specifically mean discharge under possible changed climatic conditions in the investigated catchments is already feasible today. <br><br>Simulations based on scenarios are one way to establish unknown future boundary conditions for the estimation of regional impacts of possible changes of the climate system. Nevertheless, all types of modeling and simulation of natural systems are linked with uncertainties. Rather large uncertainties persist regarding the future development of the socio-economic system and the complexity of the climate system and earth system. Furthermore, besides data uncertainties associated with the measurement of hydro-meteorological values, uncertainties associated with individual components of the model chain emission scenarios/gas cycle model - GCM/regionalization - hydrological model, which form a cascade of uncertainty, have a great influence on the trustworthiness of the simulation results (which are understood as one shown value within a range of results). <br><br>In the young field of climate impact research the use of <br>(1) robust hydrological models that adequately describe temperature-dependent processes,<br>(2) long time series (at least 30 years long) of measurements, <br>(3) concurrent comparisons of climate change scenarios, based on different GCMs (and, if possible, different emission scenarios)<br>should be considered for reasons of scientific thoroughness and to improve comparability of regional impact studies.

This thesis provides a study of an open source software project that focuses on the software development of an e-service in a municipal context. The focus is on environmental factors that either limit or promote the motivation to participate in the open source project, the "Parent-Teacher Meeting" project, a web-based communication and information channel whose purpose is to enhance the contacts between schools and parents. The empirical context is situated at the point where traditional information systems (IS) development meets new perspectives regarding organizational structures and boundaries and, as such, provides example of ongoing cross-organizational activities that break current local organizational standards. The objective of this study is to gain a deeper understanding of motivational factors for participation and adopts a sociocultural view on the topic motivation to participate. The empirical material was collected through interviews, conversations, and meetings. Being a subproject (i.e. an initiative to develop an open source software application) within a triple helix project I found an extensive number of stakeholders. The choice was made to focus on the application development; thereby a central group of participants within the development project team was found and these became the focus within the study. Moreover, I have, in this thesis, chosen to conduct a contextual description of the participants and the course of events that lead to the start of the project of study. This has been done so as to present the context, which is the focus for this study, to the reader and to be able to use these descriptions within the analysis. I have, methodologically, approached the problem from a descriptive angle with an interpretative character using a qualitative case study design. Within the thesis, the means by which the case study has been conducted is presented; i.e. the decision regarding research focus, design, and my role as researcher. In relation to the data collection, the main source has been semi-structured interviews, which is consistent with an interpretive case study character and in which my intent is to highlight conditions and events that are important to both groups within the development team. To support the investigation of those factors that can explain and assist with the interpretation of my empirical data, my description and interpretations are built on a theoretical framework based on concepts from IS theories and theories relating to human motivation. The framework, self-determination theory (SDT), is used as a lens to direct the focus onto the situated conditions that influence how individuals experience their participation within the software development project. Given the theoretical basis of an analytical comparison of ideal types of software development constructs, together with influences from motivational theories, the analytical framework used for collecting occurrences of motivational behavior and sociocultural conditions has been constructed. After the findings and my interpretation of them with the assistance of my analytical framework have been presented, a discussion and conclusions are then detailed. The conclusions of the study are argued as being relevant as an explanation for the understanding of intrinsic and internalized extrinsic motivation to participate in a hybrid open source projects. The study contributes to our understanding of some of the challenges that are to be considered when putting together and managing systems or software development processes. In this way, the study may provide some basis for improving and meeting new demands regarding how development is adopted in a mixed scenario and this provides valuable knowledge to both practice and IS research. / Grunden för denna avhandling är en studie av ett öppen källkodsutvecklingsprojekt av en kommunal e-tjänst. Fokus ligger på ett sociokulturellt perspektiv på kontextuella faktorer vilka endera hindrar eller främjar motivation för deltagande. Öppen källkodsprojektet ”Föräldramötet” är en webbaserad kommunikations- och informationskanal vars syfte är att öka och förbättra kontakten mellan hem och skola. Denna empiriska kontext är situerad i en punkt där traditionell IS-utveckling möter nya perspektiv på organisationsstrukturer och gränser samt därigenom ger exempel på pågående tvärorganisatoriska aktiviteter vilka bryter mot nuvarande interna organisationsstandarder. Målet för denna studie är att nå en djupare förståelse för deltagandets motivationsfaktorer och anammar ett sociokulturellt perspektiv på ämnet deltagandemotivation. Det empiriska materialet samlades in genom intervjuer, konversationer samt möten. Då Föräldramötetprojektet är ett underprojekt i ett trippelhelixsammanhang visade det sig initialt finnas ett stort antal intressenter. Det gjordes ett val att fokusera på applikationsutvecklingen; genom vilket en central grupp av deltagare inom utvecklingsprojektet identifierades vilka kom att komma i fokus för denna studie. Vidare har jag i denna avhandling valt att göra en kontextuell beskrivning av deltagarna och den händelsekedja som lett fram till bildandet av det studerade projektet. Detta gjordes för att i enlighet med denna studies fokus belysa sammanhanget för läsaren samt för att använda den inom min analys. Jag har närmat mig problemet från en deskriptiv synvinkel med en tolkande karaktär användande mig av en kvalitativ fallstudiemetod. Inom avhandlingen beskrivs tillvägagångssättet för fallstudiens utförande, t.ex. hur beslut fattats angående forskningsfokus, fallstudiedesign och vad min roll som forskare inneburit. I relation till datainsamlingen, har den huvudsakliga källan varit halvstrukturerade intervjuer. Dessa har varit i konsekvens med en uttolkande fallstudiemetod och har i enlighet med min avsikt utformats för att belysa villkor och händelser som har varit betydande för bägge grupperingarna inom projektgruppen. För att stödja undersökningen av de faktorer som kan förklara och hjälpa med tolkningen av mina empiriska data, har jag byggt mina beskrivningar och tolkningar på ett teoretiskt ramverk baserat på koncept från IS-teorier och teorier relaterade till mänsklig motivation. Det teoretiska ramverket ”self-determination theory” (SDT), används som en lins för att rikta brännpunkten mot de villkor som styr hur individer upplever deras deltagande inom det studerade mjukvaruutvecklingsprojektet. Givet den teoretiska bas, som bygger på analytisk karaktärisering av idealtyper av mjukvaruutvecklingsmodeller sammantaget med influenser från motivationsteorier, har ett analytiskt ramverk, för att inhämta instanser av motiverat beteende och sociokulturella villkor, utvecklats. Efter att ha redogjort för upptäckterna och mina tolkningar av dem, med hjälp av mitt analytiska ramverk, presenteras en detaljerad diskussion med slutsatser. Jag argumenterar för att dessa slutsatser är relevanta som en förklaring för förståelsen av inre samt internaliserad yttre motivation för deltagande inom detta öppen källkodsprojekt av hybridnatur. Studien bidrar till vår förståelse för vissa av de utmaningar som måste beaktas när man ska hantera system eller utvecklingsprocesser. På detta sätt kan studien bidra med en bas för att förbättra och möta nya krav på hur utveckling bedrivs i blandade miljöer och även med kunskap för både praktik och IS-forskning. / PECOI

Cette thèse comporte deux parties majeures : la première partie est dédiée à l'étude du problème sparse CARP déterministe où nous avons développé une transformation du sparse CARP en un sparse CVRP. La seconde est consacrée au problème sparse CARP avec coûts sous incertitude. Nous avons donné une formulation mathématique du problème en min-max. Cette modélisation a permis d'identifier le pire scénario pour le problème robuste. Deux approches algorithmiques ont été proposées pour une résolution approchée. / This dissertation consists of two main parts : in the first part, we study the detreministic capacitated arc routing problem over sparse underlying graphs wher we have developed a new transformation techniquevof sparse CARP into sparse CVRP. The second part is consecrated about the sparse CARP with travel costs uncertainty. We have given a mathematical formulation of the probleme in min-max. A worst scenario for the robust problem is then identified, and two algorithmic approaches are proposed to determine a solution of the studied problem.

Der Titel unseres Beitrages hätte auch lauten können: Digitale Revolution – was nun? Die Digitalisierung lässt Alles überall und jederzeit stattfinden, beschleunigt Arbeitsprozesse dramatisch, intensiviert die Kommunikation („always on“), verändert Konsum- und Freizeitverhalten und verändert die ehemals linear in Einzeldisziplinen denkbare Welt in ein komplexes, nichtlineares und disruptives System mit sehr unterschiedlichen Akteuren. Die analoge Welt besteht weiterhin, Bytes liefern weder Stoff noch Energie, sondern verbrauchen Kilojoules. Wissen um Prozesse ist Macht. Antwortsysteme auf die geschilderte Anforderungsstruktur müssen ebenfalls schnell, komplex und multidisziplinär sein. Was aber ermöglicht die dafür erforderliche schnelle und verlässliche Kommunikation? Ein Teil einer Antwort ist technisch, darauf gehen wir hier nicht ein. Ein anderer Teil hat viel damit zu tun, wie wir denken und uns in Gruppen verhalten und welche Kommunikationskultur wir nutzen. Erzählungen darüber, wer wir sind, welchen Regeln wir folgen und welche Ziele wir haben stellen den wahrscheinlich wichtigsten Mechanismus unserer Entwicklung dar und sind in Form von Modellen (Stachowiak 1973) Kern jeder Disziplin. Beispielhaft sei die Hooksche Feder als Modell für linear elastisches Werkstoffverhalten genannt; das abstraktere Modell der Elastizität ist in beinahe jedem Fach vertreten. Bei der nachträglichen Auswertung mehrerer designgetriebener Forschungsvorhaben ist zu beobachten, dass Szenarien als komplexe deskriptive und präskriptive Modellsysteme die wesentliche kulturell verankerte Kommunikationsbasis zur Zusammenarbeit in multidisziplinären Teams darstellen. Warum das so ist und wie Szenarien von multi- oder transdisziplinären Teams genutzt werden können, beschreiben wir im Folgenden.

There is a sharp increase in the number of old people living alone throughout the world. More often than not, such people require continuous and immediate care and attention in their everyday lives, hence the need for round the clock monitoring, albeit in a respectful, dignified and non-intrusive way. For example, continuous care is required when they become frail and less active, and immediate attention is required when they fall or remain in the same position for a long time. To this extent, various monitoring technologies have been developed, yet there are major improvements still to be realised. Current technologies include indoor positioning systems (IPSs) and health monitoring systems. The former relies on defined configurations of various sensors to capture a person's position within a given space in real-time. The functionality of the sensors varies depending on receiving appropriate data using WiFi, radio frequency identification (RFIO), ultrawide band (UWB), dead reckoning (OR), infrared indoor (IR), Bluetooth (BLE), acoustic signal, visible light detection, and sound signal monitoring. The systems use various algorithms to capture proximity, location detection, time of arrival, time difference of arrival angle, and received signal strength data. Health monitoring technologies capture important health data using accelerometers and gyroscope sensors. In some studies, audio fingerprinting has been used to detect indoor environment sound variation and have largely been based on recognising TV sound and songs. This has been achieved using various staging methods, including pre-processing, framing, windowing, time/frequency domain feature extraction, and post-processing. Time/frequency domain feature extraction tools used include Fourier Transforms (FTs}, Modified Discrete Cosine Transform (MDCT}, Principal Component Analysis (PCA), Mel-Frequency Cepstrum Coefficients (MFCCs), Constant Q Transform (CQT}, Local Energy centroid (LEC), and Wavelet transform. Artificial intelligence (Al) and probabilistic algorithms have also been used in IPSs to classify and predict different activities, with interesting applications in healthcare monitoring. Several tools have been applied in IPSs and audio fingerprinting. They include Radial Basis Kernel (RBF), Support Vector Machine (SVM), Decision Trees (DTs), Hidden Markov Models (HMMs), Na'ive Bayes (NB), Gaussian Mixture Modelling (GMM), Clustering algorithms, Artificial Neural Networks (ANNs), and Deep Learning (DL). Despite all these attempts, there is still a major gap for a completely non-intrusive system capable of monitoring what an elderly person living alone is doing, where and for how long, and providing a quick traffic-like risk score prompting, therefore immediate action or otherwise. In this thesis, a cost-effective and completely non-intrusive indoor positioning and activity-monitoring system for elderly people living alone has been developed, tested and validated in a typical residential living space. The proposed system works based on five phases: (1)Set-up phase that defines the typical activities of daily living (TADLs). (2)Configuration phase that optimises the implementation of the required sensors in exemplar flat No.1. (3)Learning phase whereby sounds and position data of the TADLs are collected and stored in a fingerprint reference data set. (4)Listening phase whereby real-time data is collected and compared against the reference data set to provide information as to what a person is doing, when, and for how long. (5)Alert phase whereby a health frailty score varying between O unwell to 10 healthy is generated in real-time. Two typical but different residential flats (referred to here are Flats No.1 and 2) are used in the study. The system is implemented in the bathroom, living room, and bedroom of flat No.1, which includes various floor types (carpet, tiles, laminate) to distinguish between various sounds generated upon walking on such floors. The data captured during the Learning Phase yields the reference data set and includes position and sound fingerprints. The latter is generated from tests of recording a specific TADL, thus providing time and frequency-based extracted features, frequency peak magnitude (FPM), Zero Crossing Rate (ZCR), and Root Mean Square Error (RMSE). The former is generated from distance measurement. The sampling rate of the recorded sound is 44.1kHz. Fast Fourier Transform (FFT) is applied on 0.1 seconds intervals of the recorded sound with minimisation of the spectral leakage using the Hamming window. The frequency peaks are detected from the spectrogram matrices to get the most appropriate FPM between the reference and sample data. The position detection of the monitored person is based on the distance between that captured from the learning and listening phases of the system in real-time. A typical furnished one-bedroom flat (flat No.2) is used to validate the system. The topologies and floorings of flats No.1 and No.2 are different. The validation is applied based on "happy" and "unusual" but typical behaviours. Happy ones include typical TADLs of a healthy elderly person living alone with a risk metric higher than 8. Unusual one's mimic acute or chronic activities (or lack thereof), for example, falling and remaining on the floor, or staying in bed for long periods, i.e., scenarios when an elderly person may be in a compromised situation which is detected by a sudden drop of the risk metric (lower than 4) in real-time. Machine learning classification algorithms are used to identify the location, activity, and time interval in real-time, with a promising early performance of 94% in detecting the right activity and the right room at the right time.

Master of Arts / Department of Geography / John A. Harrington Jr / Environmental degradation is a major concern in agricultural landscapes. Innovative tools and methods will be necessary to identify and deal with the ongoing environmental impacts of past and present agricultural practices. The use of scenarios in environmental modeling is one way to address these concerns. Recently a group of researchers devised a framework for creating future land cover scenarios for two physiographic regions in Iowa. Based on that work, a suite of scenarios were created for Antelope Creek watershed in the Northern Flint Hills of Kansas. The Antelope Creek scenarios represent conditions pre Euro-American settlement, present day, increased intensification of agricultural production, enhancement of water quality, and enhancement of biodiversity. These scenarios were then modeled using the Soil and Water Assessment Tool (SWAT). Additional model runs were completed to compare SSURGO and STATSGO soil datasets. Results indicated that reductions in discharge, total suspended sediment and various nitrogen and phosphorus loads could be achieved by implementing modest changes to agricultural management practices. Results also indicated that a higher detail soil dataset such as SSURGO lead to slightly higher loads than with STATSGO data.
