The Quenching and Partitioning (Q&P) heat treatment has been proposed in the early 2000s to produce cold-rolled sheets combining high-strength and formability for the automotive market. Q&P consists, first, of an interrupted quench between the martensite-start temperature (Ms) and the martensite-finish temperature (Mf) from intercritical annealing or full austenitization in order to form controlled fractions of martensite. This is followed by a partitioning step in order to stabilize the untransformed austenite through carbon enrichment. In order to maximize the carbon transfer from martensite to austenite, the use of specific alloying elements and the design of appropriate Q&P parameters are required to eliminate or minimize competing phenomena such as carbide formation and austenite decomposition. The final quenched and partitioned microstructure, using full austenitization, ideally consists of carbon-depleted lath martensite and significant fractions of retained austenite providing an improved combination of strength and ductility. Hence, the transformation of retained austenite upon straining at room temperature (TRIP effect) provides supplementary work-hardening and eventually improves the ductility. In the present work, Quenching and Partitioning (Q & P) heat treatments were carried out in a quench dilatometeron a 0.2 wt% carbon steel. The microstructure evolution of the Q & P steels was characterized usingdilatometry, SEM, EBSD and XRD. The martensitic transformation profile was analyzed in order to estimate thefraction of martensite formed at a given temperature below the martensite start temperature Ms. Q & P wasshown to be an effective way to stabilize retained austenite at room temperature. However, the measuredaustenite fractions after Q & P treatments showed significant differences when compared to the calculated valuesconsidering ideal partitioning conditions. Indeed, the measured austenite fractions were found to be less sensitiveto the quench temperature and were never larger than the ideal predicted maximum fraction. Competitivereactions such as austenite decomposition into bainite and carbide precipitation were found to occur in thepresent work.Furthermore, a broad range of mechanical properties was obtained when varying the quenching temperaturesand partitioning times. The direct contributions between Q & P microstructural constituents -such as retainedaustenite as well as tempered/fresh martensite- and resulting mechanical properties were scrutinized. This wascritically discussed and compared to quenching and austempering (QAT) which is a more conventional processingroute of stabilizing retained austenite at room temperature. Finally, Q & P steels were shown to exhibit aninteresting balance between strength and ductility. The achievement of this interesting combination of mechanicalproperties was reached for much shorter processing times compared to QAT steels. / Doctorat en Sciences de l'ingénieur et technologie / info:eu-repo/semantics/nonPublished

Esta tese investiga de que forma a ficção contemporânea de língua portuguesa encontra possibilidades de resistência à crise do romance que tem se estabelecido na contemporaneidade. As obras dos autores Bernardo Carvalho e Francisco José Viegas, inscritos no início do século XXI, permitem verificar como a ficção da era atual suplanta a crise da narrativa e inscreve-se como elemento de resistência. Com base nas teorias de Walter Benjamim, Theodor Adorno, Zygmunt Bauman e Andreas Huyssen - acerca do declínio da narrativa e do romance aliadas a questões de deslocamento, memória e identidade procuramos demonstrar que essa ficção responde a um momento de crise e de transição. Assim, a ficção dos autores investigados representa não a crise do romance, antes configurase como romance da crise, justamente por encontrar nas questões conflitantes (transgressão narrativa, deslocamento espacial, diluição da memória e identidades fluídas) os muros para a construção de seu labirinto ficcional. / This thesis investigates how the contemporary fiction of Portuguese language meets possibilities of resistance to the crisis of the romance that has established in the contemporaneity. The titles of the authors Bernardo Carvalho and Francisco José Viegas, registered in the beginning of the 21st century, allow examining how the fiction from the current era supplants the narrative crisis and inscribes itself as a resistance element. Based in the theories of Walter Benjamim, Theodor Adorno, Zygmunt Bauman and Andreas Huyssen about the decline of the narrative and the romance allied to questions of displacement, memory and identity we try to demonstrate that this fiction responds to a moment of crisis and transition. Thus, the fiction of the authors investigated represents not the crisis of the romance, before, it configures itself as romance of the crisis, justly for meeting in the conflicting questions (narrative transgression, spatial displacement, dilution of the memory and fluid identities) the walls for the construction of its fictional labyrinth.

In the 1976, the Institute of Transportation Engineers (ITE) compiled their first Handbook of guidelines and methods for evaluating development-level transportation impacts, specifically vehicular impacts (Institute of Transportation Engineers 1976). Decades later, these methods--essentially the same as when they were originally conceived--are used ubiquitously across the US and Canada. Only recently, with the guidelines in its third edition of the ITE's Trip Generation Handbook (Institute of Transportation Engineers 2014) new data and approaches have been adopted--despite substantial evidence that questions the accuracy of older data, automobile bias, and lack of sensitivity to urban contexts. This dissertation contributes to this literature by focusing on the data, methods, and assumptions so commonly included in development- or site-level evaluation of transportation impacts. These methods are omnipresent in development-level review--used in transportation impact analyses or studies (TIAs/TISs) of vehicular or mode-based impacts, vehicle miles traveled (VMT) and estimates of emissions, scaling or scoping development size, and evaluating transportation system development, impact or utility fees or charges. However, few have evaluated the underlying characteristics of these foundational data--with few exceptions--this manuscript takes aim at understanding inherent issues in the collection and application of ITE's data and methods in various urban contexts. This manuscript includes a compiled dissertation, four papers written consecutively. The first, evaluates state-of-the-art methods in Chapter 2--identifying gaps in the literature. Two such gaps are explored in Chapter 3 and Chapter 4. In Chapter 3, a larger implicit assumption present in ITE's methods--that the existing land-use taxonomy is an optimal and accurate way to describe land use and segment data. Results indicate a simplified taxonomy would provide substantial reductions in cost corresponding with a minor loss in the model's explanation of variance. Following, Chapter 4 explores a common assumption that requires ITE's vehicle trips be converted into person trips and applied across contexts. The results point to the need to consider demographics in site-level transportation impact analysis, particularly to estimate overall demand (person trips, transaction activity) at retail and service development. In Chapter 5, the findings from this research and previous studies are extrapolated to evaluate and quantify the potential bias when temporal, special, and social contexts are ignored. The results indicate the compounding overestimation of automobile demand may inflate estimation by more than 100% in contexts where ITE should be applicable (suburban areas with moderate incomes). In the conclusions (Chapter 6), the implications of this work are explored, followed by recommendations for practice and a discussion of the limitations of this research and future work.

This thesis investigates the relationship between mode choice and the complexity of trip chaining patterns. An understanding of the causality between these two choice behaviors may aid in the development of tour-based travel demand modeling systems that attempt to incorporate models of trip chaining and mode choice. The relationship between these two aspects of travel behavior is represented in this thesis by considering three different causal structures: one structure in which the trip chaining pattern is determined first and influences mode choice, another structure in which mode choice is determined first and influences the complexity of the trip chaining pattern, and a third structure in which neither is predetermined but both are determined simultaneously. The first two structures are estimated within a recursive bivariate probit modeling framework that accommodates error covariance. The simultaneous logit model is estimated for the third structure that allows a bidirectional simultaneous causality. The analysis and model estimation are performed separately for work tour and non-work tour samples drawn from the 2000 Swiss Microcensus travel survey. Model estimation results show that the causal structure in which trip chaining precedes mode choice performs best for the non-work tour sample. For the work-tour sample, the findings were less conclusive because two causal structures, one in which trip chaining affects mode choice and the other in which both are determined simultaneously, gave virtually identical goodness-of-fit measures. But the structure in which mode choice precedes trip chaining pattern choice gave significantly inferior goodness-of-fit measures for the work tour sample. These findings should be reflected in the development of activity-based and tour-based modeling systems.

Im Februar und März 2007 wurde vom Geographischen Institut der Universität eine Exkursion nach Neuseeland durchgeführt. Der hier vorliegende Bericht bezieht sich auf diese Exkursion. Im ersten Teil wird durch 17 Protokolle der Exkursionsverlauf wiedergegeben. Im zweiten Teil befassen sich sechs Texte näher mit je einem thematischen Aspekt der Exkursion. Autoren der Protokolle und der thematischen Texte sind die Teilnehmerinnen und Teilnehmer der Exkursion. Zum ersten Teil des Berichts – der Exkursionsverlauf Im ersten Teil dieses Berichtes wird der Verlauf der Exkursion Neuseeland 2007 des Geographischen Instituts der Universität Potsdam durch Tagesprotokolle dargestellt. Die Exkursion begann am 14. Februar 2007 in Auckland und endete am 4. März 2007 in Christchurch. Während dieser 19 Tage wurden verschiedene Orte auf der neuseeländischen Nord- und Südinsel aufgesucht, wobei die Exkursionsgruppe verschiedene Aspekte der neuseeländischen Gesellschaft aus einer humangeographischen Perspektive studierte. Im Mittelpunkt standen die Themen historische und jüngere Migration nach Neuseeland, Maori, Milchwirtschaft, Holzwirtschaft und Tourismus in Neuseeland. Die Tagesprotokolle machen deutlich, dass die Exkursion weniger in einer thematisch-systematischen Art und Weise durchgeführt wurde. Statt dessen erfolgte das Aufsuchen exemplarischer Orte, an denen Beobachtungen und darüber hinausgehende Erkundungen stattfanden. Die entsprechenden Aussagen sind in den Protokollen wiedergegeben, schwerpunktmäßig wird dabei folgendes angesprochen: Der erste Exkursionstag, das war der 14. Februar 2007, wurde für den Besuch des Geographischen Institutes der Auckland University genutzt. Dort wurde zum Beispiel eine Diskussionsrunde mit den beiden Humangeographen Richard Le Heron und Gordon Winder veranstaltet. Auch die folgenden zwei Tage verbrachten die Exkursionsgruppe in Auckland, wobei sie sich im »Auckland Museum« über die neuseeländische Geschichte und insbesondere über die Kultur der Maori informierte. Mit einem Maori-Guide unternahmen die Teilnehmer eine Stadtführung durch Auckland, wobei ebenfalls das Leben der Maori im Fokus stand. Außerdem besuchten sie eine private Einwanderungsagentur und führten in Kleingruppen Expertengespräche zum Thema »Migration und Integration in Neuseeland« durch. Am 17. Februar erkundeten die Exkursionsteilnehmer drei Orte in der näheren Umgebung Aucklands. Zunächst begaben sie sich zum Otara Market, einem Wochenmarkt der Pacific Islanders, der immer samstags in Otara abgehalten wird. Anschließend ging es weiter an die westliche Küste, wo sie unter Führung einer Rangerin durch den Muriwai-Regionalpark wanderten. Auf der Rückfahrt nach Auckland machten sie Halt in Soljan’s Winzerei, wo der Betrieb vorgestellt wurde und Wein verkosten werden konnte. Am 18. Februar verließ die Exkursionsgruppe Auckland in Richtung Norden, um zum Ort Puhoi zu gelangen. Dort beschäftigten sich die Teilnehmer mit den sogenannten Bohemians, die einst aus Böhmen nach Neuseeland auswanderten und deren Traditionen dort auch heute noch (zumindest teilweise) gepflegt werden. Am nächsten Tag fuhren sie weiter nach Pahia, dem nördlichsten Aufenthaltsort während der Exkursion. Auf dem Weg dorthin machten sie einen Umweg über Matakohe, wo das Kauri-Museum und der Tane Mahuta, der größte Kauribaum Neuseelands, besichtigt wurden. Am 20. Februar stand vormittags die Beschäftigung mit der Geschichte Neuseelands auf dem Tagesplan. Hierfür besuchte die Exkursionsgruppe die Waitangi Treaty Grounds. Dort informierten sich die Teilnehmer über den Vertrag von Waitangi und darüber, welche Folgen dieser für das Leben der Maori hatte. Am Nachmittag stand das Thema Tourismus im Mittelpunkt. Die Exkursionsteilnehmer machten sich mit einem Teil des touristischen Angebots vertraut, indem sie eine Bootstour durch die Bay of Islands unternahmen. Am 21. Februar fuhr die Gruppe in die Hamilton-Region, wo sie sich auch die folgenden zwei Tage aufhielt. Auf dem Weg dorthin wurde ein Zwischenstopp in Kawakawa und an den Whangarei Falls eingelegt. In Hamilton war die Exkursionsgruppe Gast im Geographischen Institut der Waikato University und im Waikato Migrant Resource Centre. Außerdem stand das Thema Milchwirtschaft auf dem Programm. Hierfür besichtigten die Teilnehmer das Unternehmen AmBreed, welches die Grundlage für die Aufzucht von Hochleistungsmilchkühen bereitstellt – nämlich das Bullensperma. Außerdem konnten sie sich über die Organisation und Probleme einer Milchfarm informieren. Darüber hinaus gestalteten in der Waikato-Region wohnende Nachfahren der böhmischen Einwanderer ein Abendprogramm für die Exkursionsgruppe. Den 24. Februar verbrachten die Teilnehmer im Gebiet von Rotorua. Dort durchkreuzten sie das Thermal Wonderland, in dem heiße Quellen und Geysire sowie die dadurch geschaffenen Oberflächengegebenheiten studiert werden können. Die heißen Quellen werden hier auch zur Energiegewinnung herangezogen, wovon sich die Exkursionsteilnehmer bei einer Besichtigung der Geothermal Power Station of Warakei überzeugen konnten. Auf der Fahrt zum Tongariro Nationalpark bewunderten sie die Huka Falls und machten Halt am Lake Taupo, dem größten See Neuseelands. Im Nationalpark unternahmen sie am 26. Februar eine Wanderung. Tags darauf fuhren sie weiter über Marton nach Wellington, der Hauptstadt Neuseelands. Dort war nachmittags sowie am 28. Februar Gelegenheit, die Stadt zu erkunden, unter anderem auf einer Stadtführung mit Prof. Bredlich. Daneben erfuhr man bei einem Besuch des neuseeländischen Nationalmuseums Te Papa viel Wissenswertes über Gesellschaft und Geschichte Neuseelands. Am 1. März überquerten sie mit der Fähre die Cookstraße, um zur Südinsel zu gelangen. Den Nachmittag dieses Tages verbrachte die Exkursionsgruppe in Upper Moutere, wo sie sich mit der Einwanderung Deutscher in der Region Nelson befasste Am Tag darauf fuhren die Teilnehmer zur Westküste und beschäftigten sich mit den Landschaftsformen der Südalpen und der Küste sowie mit der Frage, welche wirtschaftliche Rolle diese Region einst spielte und welche sie heute einnimmt. Am 3. März überquerten sie die Südalpen über den Athur’s Pass und kamen am Nachmittag in Christchurch an. Am nächsten Tag erlebten sie eine Besichtigungstour durch die größte Stadt der Südinsel unter Leitung von Prof. Parson vom Institut für Geographie der Universität von Canterbury. Dabei standen insbesondere Fragen des städtischen Wandels im Mittelpunkt, welcher mit den ökonomischen Reformen seit Ende der 80er Jahre des letzten Jahrhunderts einherging. Damit endete am 4. März die Exkursion in Christchurch. Zum zweiten Teil des Berichts – die thematischen Texte Neben dem Gewinn eines ersten Eindrucks vor Ort bietet eine Exkursion als Form der Erkundung eines Landes durchaus auch die Gelegenheit, kritisch über gesellschaftliche Vorgänge zu reflektieren. Über solche Reflexionen geben die Darstellungen im zweiten Teil dieses Exkursionsberichtes Aufschluss. Das Spektrum der in den Texten aufgegriffenen Themen reicht dabei von physisch-geographischen Gegebenheiten, über Land- und Forstwirtschaft, die Maori bis zu bevölkerungsgeographischen Fragestellungen zur Migration und Integration in Neuseeland. Dem zu Grunde liegt ein – in der Geographie lange verwurzeltes – holistisches Verständnis der Disziplin. In den Berichten findet die zentrale Debatte in der Geographie um die Bedeutung und das Zusammenspiel von globalen, regionsunabhängigen und lokalen, regionsspezifischen Faktoren (»Glokalisierung«) an vielen Stellen ihren Ausdruck. Da während der Exkursion Einblick in verschiedenste Bereiche des Lebens in Neuseeland gewonnen werden konnten, ist es im thematischen zweiten Teil des Berichts vorrangiges Ziel, einen guten Überblick über Neuseeland und seine Bevölkerung zu geben. Dabei überwiegt ein beschreibender Charakter der Texte, gleichzeitig sollen aber auch zentrale Veränderungen und Herausforderungen für die neuseeländische Gesellschaft angesprochen, Erklärungsansätze gegeben und Lösungsstrategien aufgewiesen werden. Im Einzelnen ist der thematische Teil folgendermaßen aufgebaut: Zu Beginn widmet sich Anja Lehmann den Maori und beleuchtet Geschichte, Kultur und heutige Situation der indigenen Bevölkerung Neuseelands. Anschließend gehen Katharina Popig und Manuel Hundt in ihrem Text auf die frühe europäische Einwanderung nach Neuseeland, insbesondere auf die Rolle der deutschen bzw. böhmischen Einwanderer, ein. Im darauf folgenden Text zeigt Manuel Hundt die sich verändernden Muster in der jüngeren Migration auf und beleuchtet Fragen der Integration in Neuseeland, wobei insbesondere auf die Rolle der Pacific Islanders eingegangen wird. Dann folgt der Text von Lilli Maier. Sie beschäftigt sich mit Fragen des Tourismus und schildert die Gestalt des Fremdenverkehrs und seine Bedeutung für die neuseeländische Wirtschaft. Natalia Kiselgof gibt einen Überblick sowohl über physisch-geographische Aspekte und den Naturraum Neuseelands als auch über die Struktur der neuseeländischen Landwirtschaft, bevor Sören Sturm die Forstwirtschaft Neuseelands einer kritischen Analyse unterzieht. / In February and March 2007 the Institute of Geography at Potsdam University carried out a field trip to New Zealand. The report refers to this field trip and is divided into two parts. The first part gives an account of the field trip’s course in 17 daily reports. The second part attends to different thematic aspects of the field trip, each dealt with in one of the six texts. Authors of the daily reports and the thematic texts are the participants of the field trip. Part One – The course of the field trip In the first part of this report we will depict the course of the field trip of the Institute of Geography at Potsdam University to New Zealand 2007 by means of reports for each of the field trip’s days. The field trip began on February 14, 2007 in Auckland and ended on March 4, 2007 in Christchurch. During these 19 days, the group visited different places on New Zealand’s North and South Island, in which different aspects of New Zealand’s society were studied from a human geographical perspective. In the centre of interest were topics such as historical and recent migration to New Zealand, Maori, agriculture, forestry and tourism in New Zealand. The daily reports make clear, that the field trip was not strictly conducted systematically in a thematic way. Instead, exemplary places were visited, where observation and exceeding investigations took place. The according explanations are to be found in the daily reports, some of the topics in the focus of interest were the following: The first day of the field trip, February 14, 2007, was used for a visit at the Institute of Geography at Auckland University. They organized presentations and discussions about a wide range of New Zealand and Auckland related topics, amongst others with the human geographers Richard Le Heron and Gordon Winder. For the following two days the group stayed in Auckland and visited the “Auckland Museum”, which gave a good insight into New Zealand history and especially into Maori culture. Historical and contemporary Maori life in Auckland was also in the focus of a guided tour through the city with a Maori guide. Furthermore, the group visited a private immigration agency and conducted interviews in smaller groups with experts about “migration and integration in New Zealand”. On February 17, the participants of the field trip explored three places in the surroundings of Auckland. At first they went to Otara Market, a weekly market of the Pacific Islanders community which is held every Saturday in Otara. Then they continued to Muriwai Regional Park on the Western Coast, where a guided walk with a Park Ranger took place. On the way back to Auckland, they made a last stop at Soljan’s Winery, where the owner explained the history of the family owned business and the process of winemaking. On February 18, the field trip group left Auckland northbound to reach Puhoi by midday. There the main emphasis was put on history and contemporary situation of the “Bohemians”, who once moved from Bohemia to New Zealand and whose traditions have been living on until today. On the following day, the group headed on to Pahia, the northernmost point of the field trip. On the way there, they passed Northland’s ‘Kauri Coast’, visited the Kauri Museum in Matakohe and saw New Zealand’s largest Kauri tree, the ‘Tane Mahuta’. The history of New Zealand was on the agenda for the morning of February 20: The group visited the Waitangi Treaty Grounds, where there were possibilities to find out about the contents of the Treaty of Waitangi and about its consequences for the life of the Maori in past and present times. In the afternoon tourism was in the centre of interest: The participants of the field trip got to know one of the tourist attractions of the region and went on a boat trip through the Bay of Islands. On February 21, the group continued on its course to the region of Hamilton, where it also stayed for the following two days. On the way there, they made a stop at Kawakawa and at Whangarei Falls. In Hamilton they visited the Institute of Geography at Waikato University, where they heard a talk by Jacques Poot, professor and director of the university’s Population Studies Centre. The afternoon saw a visit of the Waikato Migrant Resource Centre. Another thematic emphasis in the Hamilton Region was put on dairy farming. For this, the students visited the company ‘AmBreed’, which specialized in artificial cattle breeding and in the production of the basis of industrialized and efficient dairy farming – the production of top-rate bull’s semen. On a typical mid-sized dairy farm the group could get an insight into organization and problems of dairy farming in New Zealand. Besides, descendants of Bohemian migrants, who had once settled in the Waikato region, organized an evening programme for the field trip group including a barbeque and the playing of traditional tunes. February 24, the participants spent in the area of Rotorua, where they wandered through ‘Thermal Wonderland’. The geothermally very active area that is to be found here created interesting surface forms and colours and there were hot springs and geysers to be studied. The existing geothermal activities are also used for the generation of energy, of which the participants of the field trip could convince themselves during a visit of the Warakei Geothermal Power Station. On the journey to Tongariro National Park they admired the blue waters of the Huka Falls and made a stop at Lake Taupo, the biggest lake in New Zealand. On the next day, February 26, there was some time to explore the volcanic landscape on a day hike in Tongariro National Park. The day after, the group went on to Marton and then to Wellington. In the afternoon as well as during the next day there was time to get to know the city and to form an opinion about New Zealand’s capital, for instance during a guided tour through the town with Professor Bredlich. Furthermore, a visit of New Zealand’s National Museum ‘Te Papa’ offered plenty of information worth knowing about society and history of New Zealand. On March 1, they crossed the Cook Strait by ferry to get to New Zealand’s South Island. The afternoon was spent in the village of Upper Moutere, where the group dealt with German migration in the Nelson region. The next day, the participants went to the West Coast and took a closer look at the landscape forms of the Southern Alps and coastline as well as at the former and recent economic role of this region. On March 3, they crossed the Southern Alps via Arthur’s Pass and arrived at Christchurch in the afternoon. During the following last day of the field trip they took part in a guided tour through the biggest city of the South Island by Professor Parson from the Institute of Geography at the University of Canterbury. In the focus of his explanations were questions of urban change, which came along with the economic reforms at the end of the 1980’s. With this, the field trip to New Zealand ended in Christchurch on March 4, 2007. Part Two – The thematic texts Apart from gaining a first impression, a field trip as a way of exploring and studying a country also opens up the possibility of critically reflecting about social questions and processes. Those reflections are the centre of the following texts in the second part of this report. The range of topics dealt with in the texts reaches from physical-geographical features, agriculture and forestry as well as Maori related topics to population geographical questions regarding migration and integration in New Zealand. The choice of this wide range is based on a holistic understanding of geography, as it is deeply rooted in this discipline. One important reference, that you will find in various parts of the different reports, deals with a central debate in geography – the impact and interaction of global factors, independent of locality, and local factors, specific to certain regions (“Glocalization”). Because it was possible for the participants to get an insight into very different fields of life in New Zealand, the main aim of the second part of this report should be to give a good overview of New Zealand and its people. Predominantly, the texts are of a descriptive character, nevertheless there are many parts where crucial changes and challenges for New Zealand society shall be mentioned, explanatory approaches be given and strategies for possible solutions be shown. In detail, the thematic part is structured as follows: At first, Anja Lehmann attends to Maori life in ‘Aotearoa’ and examines history, culture and present situation of New Zealand’s indigenous population. Then, Katharina Popig and Manuel Hundt depict the early European migration to New Zealand in their text, with an emphasis on the role of German or Bohemian settlers. In the following text Manuel Hundt shines a light on changing patterns in recent migration and takes a closer look on questions of integration in New Zealand, especially regarding the role of Pacific Islanders. After that, the text by Lilli Maier deals with tourism, examining its forms and its role in New Zealand economy. Natalia Kiselgof gives an overview both of physical geographical aspects and landscape forms in New Zealand as of the structure of New Zealand agriculture. In the last text, New Zealand’s forestry is subject to a critical analysis by Sören Sturm.

Since 1992, the number of short-term mission (STM) travelers has exponentially increased for more than a decade. The purpose of STMs is to spread religious messages to local residents. In order to spread the word of God, STM travelers attempt to interact with local residents. They want to communicate with local residents in the host community and build a relationship with them. Therefore, for STM travelers their relationship with local residnets really matters. Many tourism scholars have argued that hosts-tourists interaction heavily influences both tourists and hosts. In spite of the increased popularity and the importance of host-tourist interaction in the context of STMs, STMs have received relatively little attention from the tourism research field. Accordingly, the purpose of this study is to understand short-term mission travelers' interaction with local residents within four existing theories: the theory of leisure and tourist motivation, the theory of cultural hegemony, the gift-exchange theory, and the integrative theory of cross-cultural adaptation. To reach this research aim, this study used a qualitative research design rooted in the constructivist paradigm. A total of 43 STM travelers participated in the interview of this study. Considering the concept of the cultural distance between the participant's home culture and the host culture, American and Korean STM travelers who visited Cambodia or Thailand were recruited. Also, to understand the process of participant's relationship-building and cross-cultural adaptation, both pre- and post-interviews with 26 participants were conducted. The results showed that STM travelers sought personal and interpersonal rewards from the trip, which supports the theory of leisure motivation. Also, this type of travel had similarities with alternative, mass, and volunteer tourism in terms of tourist motivation. Regarding the theory of cultural hegemony, hegemonic power was exercised through STM travelers' work. STM travelers took advantage of an opportunity to provide what locals wanted as an opportunity to spread their religious message. Furthermore, identified conflicts between Christianity and the local culture support the existence of cultural hegemony. Concerning the relationship-building process of STM travelers, the results suggested that STM travelers built their relationship with local people and God by providing a gift to them and positively evaluating receivers' responses. In terms of the theory of cross-cultural adaptation, this study found support for this theory as successful intercultural adaptation led to a personal transformation in travelers. Finally, cultural distance was considered as a dimension of the intercultural adaptation theory. Regarding the perceived cultural distance, American mission travelers reported cultural distance with the host culture whereas Korean mission travelers expressed a cultural similarity to the host cultures rather than cultural difference.
