Annotation:

Jackie Chan has had a long and consistently successful career in the entertainment industry, becoming the most universally recognized Chinese performer, second only perhaps, to Bruce Lee. His rags-to-riches path to stardom has been well documented and oft quoted. At a time when all the up-and-coming martial arts actors felt the pressure to be carbon copies of Bruce Lee, Chan made his mark on the screen by making his persona everything that Lee?s wasn?t. With 1978?s Snake in the Eagle?s Shadow and Drunken Master, Chan?s revolutionary comic and realistic persona was firmly established with audiences. Throughout the 80s and 90s, Chan remained undeniably the biggest star in the East, demonstrating wild popularity in not only Asia, but throughout Europe and Africa as well. After several failed attempts at breaking into the American market, Chan finally achieved success with 1998?s Rush Hour. Unfortunately, success in the West has come with strict limitations placed on the characters he has been allowed to play. These limitations most often manifest themselves in the sexuality and morality of the characters, as well as the dramatic opportunities available to Chan within the films. In order to keep Chan?s vast filmography ? which has recently seen him sign on to his 100th leading role ? I have separated it into three distinct stages. The first stage of his career begins with his groundbreaking turn in Snake in the Eagle?s Shadow and ends with his last Asian film before successfully breaking into Hollywood, 1998?s Who am I?. From this point on, his career takes two distinct paths: the path in Hollywood, beginning with Rush Hour, and the path in Asia, which begins with 1999?s Gorgeous. Each stage features distinct characteristics and trends with rare digression. I will provide examples from a selection of films within each stage of his career in order to clarify the traits and characteristics of the roles he has taken in each one. The purpose of this thesis is twofold. First and foremost, it will reveal the extent to which Chan faces negative stereotyping in the United States by clearly offering the contrasting positive representations he is able to achieve overseas. The second aim, which has naturally arisen from the workings of the first, is a critical look at a career that has found its actor bored with the kinds of films that have brought him worldwide fame.

Annotation:

The Intelligent Transportation System (ITS) is a cooperative system that relies on reliable and robust communication schemes among vehicles and between vehicles and their surroundings. The main objective of the ITS is to ensure the safety of vehicle drivers and pedestrians. It provides an efficient and reliable transportation system that enhances traffic management, reduces congestion time, enables smooth traffic re-routing, and avoids economic losses. An essential part of the ITS is the Vehicular Ad hoc Network (VANET). VANET enables the setup of Vehicle-to-Vehicle (V2V) as well as Vehicle-to-Infrastructure (V2I) communication platforms: the two key components in the ITS. The de-facto standard used in wireless V2V and V2I communication applications is the Dedicated Short Range Communication (DSRC). The protocol that defines the specifications for the Medium Access Control (MAC) layer and the physical layer in the DSRC is the IEEE 802.11p protocol. The IEEE 802.11p protocol and its Enhanced Distributed Channel Access (EDCA) mechanism are the main focus of this thesis. Our main objective is to develop new IEEE 802.11p-based protocol for V2V and V2I communication systems, to improve the performance of safety-related applications. These applications are of paramount importance in ITS, because their goal is to decrease the rate of vehicle collisions, and hence reduce the enormous costs associated with them. In fact, large percentage of vehicle collisions can be easily avoided with the exchange of relevant information between vehicles and the Road Side Units (RSUs) installed on the sides of the roads. In this thesis, we propose various enhancements to the IEEE 802.11p protocol to improve its performance by lowering the average end-to-end delay and increasing the average network throughput. We introduce multiple adaptive algorithms to promote the QoS support across all the Access Categories (AC) in IEEE 802.11p. We propose two adaptive backoff algorithms and two algorithms that adaptively change the values of the Arbitrary Inter-Frame Space (AIFS). Then we extend our model to be applied in a large-scale vehicular network. In this context, a multi-layer cluster-based architecture is adopted, and two new distributed time synchronization mechanisms are developed.

Bakgrund Johan Andersson som är inköpschef på PEAB menar att det finns förbättringsmöjligheter för beställningsprocessen av betong. Informationsflödet i hela försörjningskedjan, som består av PEAB, Swerock och BASF, är bristfällig som enligt parterna leder till kapacitet- och ledtidsproblem i försörjningskedjan. Syfte Syftet med den här uppsatsen är att undersöka hur beställningsprocessen av betong ser ut i försörjningskedjan, samt att lokalisera vilka delar i processen som har förbättringspotential med avseende på information-, kapacitet- och ledtidsproblem. Även att undersöka vilken materialplaneringsmetod som är mest lämplig i försörjningskedjan under de nuvarande förutsättningarna och om någon förutsättning måste ändras för att en implementering ska vara genomförbar. Likaså är syftet att undersöka vilken inverkan den eventuellt nya materialplaneringsmetoden får på försörjningskedjan. Slutsats Det återfinns förbättringspotential i försörjningskedjan med hänseende på informationsflödet. För att den valda täcktidsplaneringen ska kunna implementeras i försörjningskedjan måste några av de nuvarande miljöplaneringsfaktorerna ändras.

The craft brewing industry in New York State has grown rapidly over the past five years helped in part by New York State legislation called the Farm Brewery Act of 2012. The act imposes agricultural stipulations for breweries desiring to file for a Farm Brewing license. The hop industry will have to grow in kind to meet the Farm Brewery Act requirements. The level of growth that needs to be achieved was determined through the use of system dynamics modeling. Production volumes were calculated based on survey results from brewers and farmers. Currently, the state's hop industry is producing a surplus of hops and will be able to supply short-term brewery growth over the horizon of the next three years. It was discovered, however, that the industry is vulnerable to demand shifts and prudent action should be taken to become resilient to changes in buyer regulations and preferences: increasing the economy of scale and building collaborative relationships through farm clustering will improve the longevity of New York's hop industry.

Annotation:

Sexuella närmanden som sker via nätet är dokumenterat i ett flertal studier. Dessa närmanden kan se ut på olika sätt, ofta i form av trakasserier. Anonymitet är en förutsättning för att kunna utsätta andra för sexuella närmanden. Bakom en dataskärm kan individer låtsas vara någon annan och därmed tänja på gränserna. Människor använder internet i olika syften, bland annat för att finna sexuella partners och kärlekspartners. Syftet med denna studie är att undersöka ungdomars attityder gentemot sexuella närmanden via internet. En gymnasieskola valdes ut där 170 elever (76 killar samt 86 tjejer) i årskurs ett (n=90) och tre (n=72) fick svara på en enkät. Resultatet visade främst signifikanta skillnader mellan könen i hur respondenterna reagerade och agerade när de blivit utsatt för sexuella närmanden via chattar och forum. Tjejer tenderar att i större utsträckning reagera negativt än killar.

Annotation:

During the last decade the society and industries have been more influenced by sustainability to decrease the effect on the environment. Due to this and the tougher legal requirements from the European Union, industries and researchers have put together more effort in sustainable development. This has led to a more focused view on reverse logistics to enhance the recycling of materials and reduce transportation. The purpose of this work has been to plot and analyze the return flow in paper industry. To see how reverse logistics could contribute to a sustainable society and increase the profitability of companies. The work is a case study for BillerudKorsnäs at the Customer Service Mill department. The information about the return flow at the case study company has been acquired through interviews and organized visits. The acquired information has then been analyzed with the help of the theory and summarized in the conclusion with the factors that affect the return flow with improvement proposal for a more sustainable and profitable return handling. The study shows that for an effective return flow in paper industry an organization for return handling need to be created. They also need to work with forecasting and follow-up of the defect material to reduce unnecessary transportation and protect the environment. Keywords: reverse logistics, supply chain, lean, hållbarhet
De senaste årtiondena har både samhället och industrier blivit allt mer påverkad av synen på hållbarhet för att minska påverkan på miljön. Hårdare lagkrav från Europeiska unionen har lett till att industrier och forskare lagt ner allt större resurser inom hållbar utveckling. Det har bland annat resulterat i en mer fokuserad syn på omvänd logistik för att öka återvinning av material och minska transporter. Syftet med detta arbete har varit att kartlägga vilka faktorer som styr returflöden och utifrån ett leanperspektiv undersöka och ge förslag på hur omvänd logistik kan bidra till ett mer hållbart samhälle samt öka lönsamheten hos företag. Arbetet är en fallstudie som utförts åt BillerudKorsnäs på avdelningen Customer Service Mill. Genom intervjuer och organiserade besök har projektgruppen erhållit information och förståelse för returhantering hos fallstudieföretaget. Denna information har sedan ställts mot teorin som resulterat i en slutsats med faktorer som påverkar returflödet samt förbättringsförslag för en mer hållbar och lönsam returhantering. Studien visar att för att erhålla ett effektivt returflöde inom pappersindustrin bör en organisation för returhantering sättas upp. Det bör även ske en prognostisering samt uppföljning av det defekta materialet för att minska onödiga transporter samt värna om en hållbar miljö. Nyckelord: reverse logistics, supply chain, lean, hållbarhet

A risk can be described as a situation that can negatively affect the development of an activity and the people involved that. In this sense, risk management is used to achieve a reduction or elimination of risk. The objective of the investigation was to determine factors that caused the low value of crop yield in a Peruvian banana supply chain. The research applied House of Risk (HOR) model to determine risk event and associated causes. As a result, strategies were proposed to mitigate the occurrence of risks in the company.

Annotation:

My work seeks to simulate the impermanence of memory, through the creation of structures and images that translate the mind’s formless but living past into physical material and sensation. The need to search for the missing six years of my childhood memories in Thailand has been the driving force behind the works, along with the lingering emotions of emptiness and unfulfillment. I create multimedia installations with materials, such as plaster, pvc panels, acrylic, polycrylic and dura-lar, to structurally realize a subject as intangible and elusive as memory. Issues of duality, identity, impermanence and memory are underlying themes for my thesis investigation. Dreamfall is a simulated, dream-like landscape where the pervading sense of solitude exists throughout the sparsity and whiteness of the installation. It is a place for contemplation and silence, a landscape of the past relived.

Annotation:

DinBox Sverige AB säljer fastighetsboxar på den skandinaviska marknaden och har produktionen utlagd till en leverantör Kina. Företaget startades i slutet på 2007 och är med andra ord relativt ungt. Den logistiska delen från beställning till leverans av produkt, är en mycket viktig och vital del av verksamheten som måste fungera. Det logistiska flödet fungerar idag inte helt felfritt och det uppstår problem med leveranser.

Jag fick som uppgift i mitt examensarbete inom supply-chain management, att undersöka det logistiska flödet närmare för att hitta olika förbättringsförslag.

Syftet med uppgiften är ta reda på vilka fel som uppstår, kartlägga vilka typer av kostnader dessa fel innebär och utreda hur man kan undvika fel i fortsättningen. Examensarbetet ska resultera i ett passande förbättringsalternativ som ökar kontrollen av logistikflödet från beställning till leverans.

Resultatet i examensarbetet har uppnåtts genom en grundlig nulägesanalys, framtagande av ett flödesschema och identifiering av problem i processerna. Problemen har brytits ned i grundorsaker och detta ligger till grund för förbättringsalternativen.

Det slutliga förbättringsförslaget innebär att kommunikation mellan alla berörda enheter hos företaget och leverantören i Kina sker i ett extranät. När ordern passerar genom logistikflödet måste aktuell enhet kontrollera och godkänna ordern innan den kan skickas vidare till nästa enhet. På så sätt får man ett kontrollsystem som säkerställer att ordern behandlas rätt från början till slut i flödet. Extranätet ger också möjligheten till spårning eftersom data kan lagras och användas för att spåra information och gods i logistikflödet. Inventeringen vid lagerankomst förenklas och säkerställs genom införandet av ett streckkodsystem som innebär att artiklar automatiskt kan identifieras.

Slutsatsen av examensarbetet är att en grundlig förstudie och nulägesanalys är mycket viktigt för att kunna identifiera de mest kostsamma och kritiska problemen i logistikflödet. Genom förbättringar av processer inom området för supply-chain finns det mycket som kan effektiviseras och spara pengar för företaget.

DinBox Sverige AB sells mailboxes on the scandinavian market with production outsourced to a supplier in China. The company started in the end of 2007, relatively young in other words. The logistical flow from order to delivery of product, is a very important and vital part of the business. The logisticial flow is today not flawless and there are problems with deliveries.

I was assigned within my thesis in supply-chain management the task to investigate the logistical flow in detail in order to suggest improvements.

The purpose of the task is to find what problems that occur, map out what costs these problems cause and investigate how to avoid errors in the future. The thesis should result in a fitting suggestion for improvement that decreases the control of the logistical flow from order to delivery.

The result of the thesis has been achieved through a thorough analysis of the present situation, making a flowchart and identifying the problems in the processes. The problems have been broken down in to main causes and are subject for the suggestions of improvement.

The final suggestion of improvement means communication between involved parties in the company and the supplier in China takes place in an extranet. When the order passes through the logistical flow every part has to control and approve the order before it is passed on to the next part. In that way a control system that secures the appropriate handling of the order throughout the flow is achieved. The extranet also gives the possibility to tracking information and goods in the logistical flow since the data can be stored in the system. The inventory when goods arrive is simplified and secured by implementing a barcode system which means all articles are automatically identified.

The conclusion of the thesis is that a thorough preliminary study and analysis of the present situation are crucial for identifying the most costly and critical problems in the logistical flow. By improvements of processes within the area of supply-chain there are a lot that can be made more efficient and save money for the company.

Målet med denna studie är att hjälpa fallföretaget med att minska materialhanteringen på avdelningen internlogistik, som bland annat innefattar godsmottagning och lagerhantering. Detta kommer att göras genom framtagning av en ny anläggningslayout. Genom automatisering av utlastningen och den nya layouten reduceras och/eller elimineras slöserier i form av transport, tid, etc. samtidigt som ett effektivare flöde skapas internt på företaget. För att kunna genomföra denna studien har kvalitativa och kvantitativa metoder använts vid datainsamlingen för att säkerställa att studien erhåller en hög vetenskaplig trovärdighet. Bakgrunden till att studien genomfördes är för att det blivit en svårighet för växande industriföretag att kunna hantera materialhanteringen på grund av för mycket arbete och kunna ha en effektiv internlogistik. Detta i sin tur ligger i grund för företag att kunna uppnå hög utnyttjandegrad, effektivt flöde och en välplanerad internlogistik för att kunna bli starkare gentemot konkurrenterna.

Annotation:

Ämnet hållbarhet är mer aktuellt idag än någonsin och en stor uppmärksamhet riktas idag mot tillverkningsföretag i Sverige. Denna uppmärksamhet och en ökad medvetenhet om de strategiska konkurrensfördelarna som mer hållbara tillvägagångssätt kan medföra, har lett till ökade hållbarhetsinsatser hos svenska tillverkningsföretag. En hållbar logistik är avgörande för alla företag som önskar minska sin negativa påverkan på denna planet. Denna kvalitativa studie visar hur tillverkningsföretag i norra Sverige idag arbetar med hållbarhet inom sin logistik. Studiens syfte är att skapa en djupare förståelse om hållbarhetstrender inom tillverkningsföretag för att sedan identifiera och presentera gemensamma trender. Förutom detta ges även rekommendationer på alternativa lösningar som tillverkningsföretag i framtiden kan implementera för att bygga på sina redan existerande hållbarhetsåtgärder. Studiens kunskapsbidrag blir således en djupare förståelse om gemensamma hållbarhetstrender inom tillverkningsföretag i Norra Sverige. Vidare har även ett teoretiskt bidrag givits i hållbarhetsmodellen Piekarski – Zemhret Sustainability Model, modellen förklarar vad som krävs för att uppnå långsiktig hållbarhet. Intervjuguiden och den teoretiska referensramen är indelad efter fyra teman;hållbarhet, industrins behov, incitament till hållbar förändring och hållbarhetsutmaningar i framtiden. Empirin har samlats in genom fem separata semi-strukturerade intervjuer med tillverkningsföretag i norra Sverige. Den insamlade data visar hur de tillfrågade företagen arbetar med hållbarhet inom sin logistik. Den ger även en förstahandsinsyn om vilka sociala, ekologiska och ekonomiska faktorer som driver tillverkningsföretagens arbete med hållbarhet inom deras logistik. En analys av empirin identifierar totalt sex hållbarhetstrender som delas av en majoritet av företagen som intervjuats. Bland dessa trender ingår bland annat arbete med riskhantering genom logistikkedjan och intresset för en framtida implementering av returlogistik och en mer cirkulär ekonomi. Analyskapitlet refererar sedan till den teoretiska referensramen för att förklara hur och varför de gemensamma hållbarhetstrender som identifierats växt fram. Baserat på analysen har två rekommendationer med alternativa lösningar givits. Dessa rekommendationer är en ökad användning av digitala verktyg och implementeringen av cirkulär ekonomi. Båda alternativen valdes på grund av dess goda möjlighet att uppnå en långsiktig hållbarhet inom logistikkedjan för tillverkningsföretag i norra Sverige. Detta eftersom båda alternativen gynnar hållbarhetens alla tre pelare (social, ekologisk och ekonomisk) som tillsammans med incitament och behov enligt Piekarski – Zemhret Sustainability Model är avgörande för att kunna uppnå långsiktig hållbarhet.

Annotation:

This thesis explores the factors underlying environmental behaviour change on Cu Lao Cham in Vietnam. It is widely recognised that residents have changed their environmental behaviour since the Cu Lao Cham Islands and surrounding marine areas became a Marine Protected Area (MPA) in 2005. The research was conducted using a qualitative approach that examined the views and experiences of islanders, as well as the meaning of their behaviour. Interviews were conducted with local people, local leaders, local officials, MPA staff, researchers, NGO staff, international agencies and tourists. Since the MPA was established, environmental behaviour changes developed under the influence of five different MPA projects. These were: restricted fishing zones, crab conservation, banning plastic bags, classification of solid waste and turtle recovery. The study found that the people changed their behaviour from passive implementation of the regulations and guidance by the MPA to actively acquiring knowledge and changing attitudes and behaviour. New attitudes and behaviour were gradually internalised. People began by reluctantly following regulations initiated by the MPA and then internalised the behaviours as they recognised the value of the changes. This process opposes dominant models and theories of behaviour change which predict that attitude and intention need to change before behaviour. The study argues that CLC people already had a strong sense of place and a desire to improve their livelihoods that motivated them to take actions towards protecting their place, once they recognised the benefits of MPA initiatives. During the course of implementing marine conservation, the people’s livelihoods were improved by the emerging tourism market which resulted from improved conservation. The main argument of this study is that environmental behaviour change can come from the lead of outsiders, combined with the insiders’ motivation, good governance and leadership.

Politics' demand for informative consumption-based emission assessments based on multi-regional input output (MRIO) databases is steadily increasing. Based on the MRIO database EXIOBASE 3, we exemplify the utility of a range of analytical tools and discus their potential insights for consumption-based policies. The analysis decomposes the overall EU carbon footprint into product groups as well as into emitting regions. Subsequently, we illustrate the potential of applying production layer decomposition (PLD) and structural path analysis (SPA) for the assessment of global supply-chains related to the EU carbon footprint and their structural changes over time. We close with some policy ecommendations on reducing carbon footprint hot spots.

Enligt den svenska skollagen ska alla elever ha rätt till en utbildning av hög kvalité och det är skolornas jobb att se till att alla elever, oavsett familjebakgrund och socioekonomisk bakgrund, får tillgång till detta. Forskningen säger att det finns tydliga skillnader mellan svenska elever och elever med annat ursprung i deras skolresultat. Denna studie syftar till att se hur resultaten i läsförståelse och matematik skiljer sig när eleverna har olika ursprung, samt att se vilken betydelse för resultatet ursprunget har när socioekonomisk bakgrund, kön och språk i hemmet läggs in i analysen. Detta undersöks med ett befintligt dataset från OECD, med resultat från PISAs undersökning 2018. Bourdieus begrepp reproduktion, fält och kapital ligger till grund för tolkningen av resultatet och kompletteras av Bernsteins teori om språk. De analyser som genomförts är multipla regressionsanalyser, där den första har resultat i läsförståelse som beroende variabel och den andra har resultat i matematik som beroende variabel. Detta för att kunna jämföra resultaten från analyserna med varandra och se om det skiljer sig mellan ämnena. Resultatet visar att elever med svenskt ursprung, svenska som språk i hemmet och föräldrar med högre utbildning presterar bättre på test i läsförståelse och matematik. Avslutningsvis diskuteras resultatet utifrån vald teori, tidigare forskning och val av metod.

Annotation:

Le protocole IEEE 802.11, basé sur les principes CMSA/CA, est largement déployé dans les communications sans fil actuelles, principalement en raison de sa simplicité et sa mise en œuvre à faible coût. Une utilisation intéressante de ce protocole peut être trouvée dans les réseaux sans fil multi-sauts, où les communications entre les nœuds peuvent impliquer l'emploi de nœuds relais. Une topologie simple de ces réseaux impliquant une source et une destination est communément connue en tant que chaîne. Dans cette thèse, un modèle hiérarchique, composé de deux niveaux, est présenté dans le but d'analyser la performance associée à ces chaînes. Le niveau supérieur modélise la topologie de la chaîne et le niveau inférieur modélise chacun de ses nœuds. On estime les performances de la chaîne, en termes de débit obtenu et de pertes de datagrammes, en fonction de différents modes de qualité du canal. En termes de précision, le modèle offre, en général, des résultats justes. Par ailleurs, le temps nécessaire à sa résolution reste très faible. Le modèle proposé est ensuite appliqué aux chaînes avec deux, trois et quatre nœuds, en présence de stations cachées potentielles, de tampons finis et d'une couche physique non idéale. Par ailleurs, l'utilisation du modèle proposé permet de mettre en évidence certaines propriétés inhérentes à ces réseaux. Par exemple, on peut montrer que la chaîne présente un maximum de performance (en ce qui concerne le débit atteint) en fonction du niveau de charge de du système, et que cette performance s'effondre par l'augmentation de cette charge. Cela représente un comportement non trivial des réseaux sans fil et il ne peut pas être facilement identifié. Cependant, le modèle capture cet effet non évident. Finalement, certains impacts sur les performances des chaînes occasionnés par les mécanismes IEEE 802.11 sont analysés et détaillés. La forte synchronisation entre les nœuds d'une chaîne et comment cette synchronisation représente un défi pour la modélisation de ces réseaux sont décrites. Le modèle proposé permet de surmonter cet obstacle et d'assurer une évaluation facile des performances de la chaîne
The IEEE 802.11 protocol, based on the CMSA/CA principles, is widely deployed in current communications, mostly due to its simplicity and low cost implementation. One common usage can be found in multi-hop wireless networks, where communications between nodes may involve relay nodes. A simple topology of these networks including one source and one destination is commonly known as a chain. In this thesis, a hierarchical modeling framework, composed of two levels, is presented in order to analyze the associated performance of such chains. The upper level models the chain topology and the lower level models each of its nodes. It estimates the performance of the chain in terms of the attained throughput and datagram losses, according to different patterns of channel degradation. In terms of precision, the model delivers, in general, accurate results. Furthermore, the time needed for solving it remains very small. The proposed model is then applied to chains with 2, 3 and 4 nodes, in the presence of occasional hidden nodes, finite buffers and non-perfect physical layer. Moreover, the use of the proposed model allows us to highlight some inherent properties to such networks. For instance, it is shown that a chain presents a performance maximum (with regards to the attained throughput) according to the system workload level, and this performance collapses with the increase of the workload. This represents a non-trivial behavior of wireless networks and cannot be easily identified. However, the model captures this non-trivial effect. Finally, some of the impacts in chains performance due to the IEEE 802.11 mechanisms are analyzed and detailed. The strong synchronization among nodes of a chain is depicted and how it represents a challenge for the modeling of such networks. The proposed model overcomes this obstacle and allows an easy evaluation of the chain performance

A Mobile Ad hoc Network (MANET) is a collection of wireless mobile nodes forming a temporary network without the need for base stations or any other preexisting network infrastructure. In a peer-to-peer fashion, mobile nodes can communicate with each other by using wireless multihop communication. Due to its low cost, high flexibility, fast network establishment and self-reconfiguration, ad hoc networking has received much interest during the last ten years. However, without a fixed infrastructure, frequent path changes cause significant numbers of routing packets to discover new paths, leading to increased network congestion and transmission latency over fixed networks. Many on-demand routing protocols have been developed by using various routing mobility metrics to choose the most reliable routes, while dealing with the primary obstacle caused by node mobility. ¶ In the first part, we have developed an analysis framework for mobility metrics in random mobility model. Unlike previous research, where the mobility metrics were mostly studied by simulations, we derive the analytical expressions of mobility metrics, including link persistence, link duration, link availability, link residual time, link change rate and their path equivalents. We also show relationships between the different metrics, where they exist. Such exact expressions constitute precise mathematical relationships between network connectivity and node mobility. ¶ We further validate our analysis framework in Random Walk Mobility model (RWMM). Regarding constant or random variable node velocity, we construct the transition matrix of Markov Chain Model through the analysis of the PDF of node separation after one epoch. In addition, we present intuitive and simple expressions for the link residual time and link duration, for the RWMM, which relate them directly to the ratio between transmission range and node speed. We also illustrate the relationship between link change rate and link duration. Finally, simulation results for all mentioned mobility metrics are reported which match well the proposed analytical framework. ¶ In the second part, we investigate the mobility metric applications on caching strategies and hierarchy routing algorithm. When on-demand routing employed, stale route cache information and frequent new-route discovery in processes in MANETs generate considerable routing delay and overhead. This thesis proposes a practical route caching strategy to minimize routing delay and/or overhead by setting route cache timeout to a mobility metric, the expected path residual time. The strategy is independent of network traffic load and adapts to various non-identical link duration distributions, so it is feasible to implement in a real-time route caching scheme. Calculated results show that the routing delay achieved by the route caching scheme is only marginally more than the theoretically determined minimum. Simulation in NS-2 demonstrates that the end-to-end delay from DSR routing can be remarkably reduced by our caching scheme. By using overhead analysis model, we demonstrate that the minimum routing overhead can be achieved by increasing timeout to around twice the expected path residual time, without significant increase in routing delay. ¶ Apart from route cache, this thesis also addresses link cache strategy which has the potential to utilize route information more efficiently than a route cache scheme. Unlike some previous link cache schemes delete links at some fixed time after they enter the cache, we proposes using either the expected path duration or the link residual time as the link cache timeout. Simulation results in NS-2 show that both of the proposed link caching schemes can improve network performance in the DSR by reducing dropped data packets, latency and routing overhead, with the link residual time scheme out-performing the path duration scheme. ¶ To deal with large-scale MANETs, this thesis presents an adaptive k-hop clustering algorithm (AdpKHop), which selects clusterhead (CH) by our CH selection metrics. The proposed CH selection criteria enable that the chosen CHs are closer to the cluster centroid and more stable than other cluster members with respect to node mobility. By using merging threshold which is based on the CH selection metric, 1-hop clusters can merge to k-hop clusters, where the size of each k-hop cluster adapts to the node mobility of the chosen CH. Moreover, we propose a routing overhead analysis model for k-hop clustering algorithm, which is determined by a range of network parameters, such as link change rate (related to node mobility), node degree and cluster density. Through the overhead analysis, we show that an optimal k-hop cluster density does exist, which is independent of node mobility. Therefore, the corresponding optimal cluster merging threshold can be employed to efficiently organise k-hop clusters to achieve minimum routing overhead, which is highly desirable in large-scale networks. ¶ The work presented in this thesis provides a sound basis for future research on mobility analysis for mobile ad hoc networks, in aspects such as mobility metrics, caching strategies and k-hop clustering routing protocols.

Syftet med denna studie var att undersöka hur läkemedelsassisterad rehabilitering vid opioidberoende (LARO) skildras i svensk media. Materialet till studien består av 82 stycken artiklar. 57 artiklar från perioden innan verksamheten byggdes ut år 2004 och 25 artiklar från de senaste tre åren. LARO-verksamheten har sedan den startade setts som kontroversiell och dessa tidsperioder valdes ut för att undersöka hur skildringarna har förändrats över tid. Från en tidsperiod där LARO-diskussionen är extra aktuell, till hur den ser ut idag. Hur LARO-verksamheten skildras i media blir intressant, då synen på missbruk och personer med missbruksproblematik påverkar vilka typer av insatser och behandlingar som används. Det blir även viktigt för socialarbetare inom missbruksvården att veta hur debatten förs i svensk media. Detta eftersom debatten kan påverka politiska beslut samt klientens och närståendes förväntningar på missbruksvården. En tematisk analys har gjorts och tre teman framträder från första perioden vilka är: Stort behov, En behandling med många fördelar samt Svensk ideologi förhindrar hjälp. Utöver detta framkommer två teman ur materialet från andra perioden vilka är: Svensk narkotikapolitik i förändring samt Förändringarnas baksida. De teorierna som använts för att förstå resultatet är systemteori och stigmateori. Viktiga slutsatser som dras är att de tidigare artiklarna fokuserar mestadels på behov som personer med opioidberoende har samt positiva effekter av behandlingen. Klienterna beskrivs här i en beroendesituation och medias skildring kan här bidra till stigmatisering. Materialet från den senare perioden fokuserar mer på ideologi och en förändrad narkotikapolitik. I dessa artiklar kommer klienter och närstående oftare till tals och läsare får ett inifrånperspektiv som kan gynna behandlingens klientel. Utöver detta talas det här om läckage och läckagets konsekvenser, vilket kan leda till att behandlingen samt dess klienters karaktär ifrågasätts. Likaså kan detta skapa oro att behandlingsmetoden återigen kommer att bli mer restriktiv.

This thesis is a critical evaluation of the theory and practice of Sustainable Supply Chain Management (SSCM). It seeks to understand why SSCM theory has so little to say about environmental sustainability and to explore how SSCM practice is contributing towards the transition towards sustainable development. I conjecture that SSCM scholars have not engaged sufficiently with the broader sustainability literature and other constructions of sustainability, which has led to a lack of theory development within SSCM. The sustainability paradigms framework that forms the core of the thesis was developed in order to broaden the discussion around sustainability within SSCM. Specifically, it embraces the contested nature of the concept of sustainability and uses multiple sustainability paradigms to construct future directions for theory development. In order to put the concept of environmental sustainability at the centre of SSCM theory, the concept of ‘environmental effectiveness’ was developed which seeks to differentiate between environmentally sustainable strategies and those that merely seek to achieve reductions in unsustainability. In order to evaluate the practice of SSCM, a case study was conducted. The concept of ‘environmental effectiveness’ is operationalized through the use of non-perceptual measures related to carbon emissions and evaluates the extent to which SSCM practices contribute towards climate stabilization, a key sustainability objective. It is found that those SSCM practices that have been shown to improve ‘environmental performance’ within the extant SSCM literature did not deliver ‘environmentally effective performance’ within the case study. This raises the possibility that the literature has mistaken reductions in unsustainability for sustainability proper and that we may need to go back to basics. The findings are discussed with reference to the sustainability paradigms framework and multiple opportunities for theory development within SSCM are explored.

Det blir allt viktigare med en väl fungerande flödeskedja som kan hantera material och tjänster på ett så effektivt sätt som möjligt. Studier visar på att det är flödeskedjorna som konkurrerar med varandra och inte företagen, vilket medför att kedjorna behöver vara konkurrenskraftiga. Detta sker genom att de aktiviteter som flödeskedjan består av integreras med varandra för att minimera slöseri av värdefulla resurser. Den tekniska utvecklingen har möjliggjort effektiv integrering med hjälp av automatisering. Implementering och införande av automatisering i flödeskedjan ökar möjligheten till att integrera olika aktiviteter inom kedjan då det bland annat möjliggör datainsamling av information som kan delas och spridas genom hela flödeskedjan. Syftet med denna studie är att kartlägga och analysera flödeskedjan för materialförsörjning hos fallföretaget LKAB, för att sedan utreda huruvida de med hjälp av automatisering och utveckling av de processer som kedjan består av kan förbättra sin produktivitet. Studien fokuserar på processerna i materialförsörjningen ända från den hubbverksamhet som i dagsläget används, hela vägen till de interna slutkunderna, vilket är de anställda på LKAB. Målet med studien är att leverera konkreta förslag som är väl anpassade efter företagets miljö och som fokuserar på de interna slutkunderna. Utifrån den nulägesbild som togs fram med hjälp av intervjuer, observationer och genomgångar, tillsammans med den genomförda litteraturstudien, analyserades de olika processerna i flödeskedjan. Genom analysen framgick det bland annat att det arbete som utförs vid hubbverksamheten inte är integrerat med resterande delar av flödeskedjan. Utöver detta framgick det att det nuvarande arbetssättet vid centralförrådet och framförallt godsmottagningen involverar mycket manuellt men nödvändigt arbete. Litteraturstudien användes sedan för att utvärdera och identifiera tänkbara lösningar för att effektivisera dessa processer för att uppnå ökad produktivitet i flödeskedjan. Via studien framgick det att automatisering leder till ökad produktivitet genom bland annat avlastning av manuellt arbete, ökad arbetsproduktivitet och minskade ledtider. Utifrån detta studerades och analyserades tre olika automatiseringslösningar, streckkod-, RFID-, och IoT-lösningar. Resultatet visade på att de tre olika lösningarna har olika fördelar och utmaningar kopplade till en implementering hos fallföretaget. Av de tre lösningarna anses streckkoder vara minst fördelaktig men också medföra minst utmaningar, medan RFID och IoT är mer fördelaktiga men också är kopplade till större utmaningar. Rekommendationerna till LKAB är att optimera det befintliga arbetet med cross-docking som i nuläget utförs vid hubbverksamheten. Detta genom att utveckla uppdelningen av gods för att minska dubbelhantering av gods i flödeskedjan. Fallföretaget rekommenderas även att implementera RFID-, och IoT-märkning av gods, för att minimera den manuella hanteringen, öka spårbarheten och öka flexibiliteten. En implementering av dessa rekommendationer skapar möjlighet till att delar av det inkommande godset inte längre behöver hanteras i centralförrådet. Detta gäller för det gods som ska levereras direkt till de interna slutkunderna och därmed inte lagerläggas.
The importance of a well-functioning supply chain that can handle materials and services in the most efficient way possible is increasing. According to several studies it is the supply chains that compete with each other rather than the companies themselves, which implies requirements for competitive chains. This can be done by integrating the activities in the supply chain with each other, in order to minimize waste of valuable resources. The development of technology has enabled effective integration through automation. Implementation of automation in the supply chain increases the ability to integrate different activities within the chain, as it, among other things, enables data collection of information that can be shared and spread throughout the entire supply chain. The purpose of this study is to map and analyze the material supply chain at LKAB, followed by investigating whether, through automation and development of the consisting processes of the supply chain, they can improve their productivity. The study focuses on all the activities in the material supply chain, from the hub that is currently in use, to the internal end customer, which are the employees at LKAB. The purpose of the study is to develop concrete proposals that are well adapted to the company's environment and with focus on the internal end customers. Based on the image of the current situation, developed using interviews, observations and reviews, along with the conducted literature study, the different activities of the supply chain were analyzed. Through the analysis it was noted, among other things, that the work performed in the hub is not integrated with the remaining parts of the supply chain. In addition to this, it was found that the current procedure of work at the central warehouse, and especially the goods reception, involves a lot of manual but necessary work. The literature study was then used to evaluate and identify possible solutions to streamline these processes in order to achieve increased productivity in the supply chain. Through the study, it was found that automation leads to an increase in productivity though, among other things, relieving of manual work, increased labor productivity and reduced lead times. Based on this, three different automation solutions, barcode, RFID and IoT solutions were studied and analyzed. The results from this showed that the three different solutions have different advantages and challenges linked to an implementation at the case company. Out of the three solutions, barcodes are considered to be the least advantageous but it also involves the least amount of challenges, while RFID and IoT are more beneficial but in turn are connected to greater challenges. The recommendations to LKAB are firstly to optimize the already existing work with cross docking performed at the hub. This by developing the division of goods to reduce the dual processing of goods in the supply chain. The second recommendation to the case company is to implement RFID, and IoT marking of goods, to minimize manual handling, increase traceability, and increase flexibility. An implementation of these recommendations will also enable some parts of the incoming goods to no longer require being handled in the central warehouse. These parts include the goods that are to be delivered directly to the internal end customer and thus not being stored.

The project aim is to determine if good quality DNA can be extracted from barley, malt and hop, ingredients used in beer brewing. Good quality DNA is important in DNA fingerprinting techniques which can be used for identification of ingredients. The 3 methods tested are the cetyltrimethylammonium bromide (CTAB) method, QIAGEN DNeasy Plant Mini Kit and Meyer’s method as published in 1996 with QIAGEN DNeasy Plant Mini Kit in combination. To evaluate the DNA quality after extraction we used 3 different techniques:

(i) spectrophotometry to estimate purity by using the ratio A260/A280; (ii) agarose gel electrophoresis after DNA extraction to determine the success of the extraction and evaluate the amount of high molecular weight DNA and degradation; and (iii) the polymerase chain reaction with 4 different primer pairs, together with agarose gel electrophoresis, to determine if the extracted DNA could be used in downstream applications, see the effect of inhibitors and estimate the fragmentisation of the DNA. The results achieved using the above mentioned methods were then used to evaluate the success of each of the extraction methods in their function of extracting high quality DNA from barley, malt and hop as well as determining whether the treatment of the ingredients has an effect on the DNA quality.

I takt med att samhället förändras och antalet unga med psykisk ohälsa ökar utvecklas och förändras även de hjälpformar som finns tillgängliga för ungdomar med psykisk ohälsa. Internets framväxt har bland annat resulterat i att traditionella former av hjälp, där den unge möter den professionella ansikte mot ansikte, har kompletterats med onlinehjälp så som onlinechattar. Med hänsyn till denna utveckling syftar denna studie till att undersöka och jämföra ungdomars attityder till att söka hjälp hos kurator och via onlinechatt vid psykisk ohälsa. Detta har åstadkommits med hjälp av ett kvantitativt tillvägagångssätt där pappersenkäter använts som insamlingsmetod. Sammanlagt besvarades enkäterna av 223 högstadie- och gymnasieungdomar mellan 15-20 år i Stockholmsområdet. Studiens resultat visar att ungdomarna känner större tillit till kuratorer än onlinechattar. De är även mer positiva till att söka hjälp hos kurator än via onlinechatt vid psykisk ohälsa. Ungdomarna uppgav varierande svar på vad som påverkar deras attityder till att söka respektive hjälpform. Lättillgänglighet, tillit och kommunikationsform uppgavs vara de faktorer som främst påverkar deras vilja att söka hjälpa hos kurator medan brist på tillit och stigma främst påverkar deras ovilja att söka denna hjälpform. De respondenter som kunde tänka sig att söka hjälp via onlinechatt uppgav däremot lättillgänglighet och anonymiteten som främsta anledningar. Den majoritet som inte kunde tänka sig att söka hjälp via onlinechatt uppgav brist på tillit och kännedom samt kommunikationsform som främsta orsaker till att inte söka denna hjälpform. Studiens respondenter är inte bara mer positiva till att söka hjälp hos kurator än via onlinechatt vid psykisk ohälsa; de har dessutom mer erfarenhet av att söka denna hjälpform. De faktorer som ungdomarna upplevde som positiva och negativa med sina erfarenheter skiljde sig dock avsevärt från de faktorer som påverkade deras attityder till att söka respektive hjälpform. Ungdomarna uppmärksammade exempelvis den professionellas bemötande och om de fick hjälp med sitt problem som positiva och negativa faktorer som utmärkte deras erfarenheter. Generellt hade dock majoriteten av ungdomarna positiva erfarenheter av att söka hjälp hos både kuratorer och onlinechattar.
In pace with changes in society, and as the number of youth with mental illness increases, the forms of help available to youth with mental health issues also develop and change. The evolution of the internet, among other things, has resulted in traditional forms of help, where the one meets a professional face-to-face, being supplemented with online forms of help, such as online chats. In view of this development, this study aims to examine and compare the attitudes of young individuals towards seeking help for mental illnesses from a counselor and an online chat. This thesis will be accomplished using a quantitative approach where paper questionnaires are used as a data collection method. A total of 223 questionnaires were answered by adolescents aged 15-20 years in the Stockholm area. The study’s results show that respondents feel more secure with and trust towards a counselor’s help and are also more likely to seek this form of help than online chat. Responses varied in regards to what affected attitudes toward each form of assistance, but ease of access, trust and the medium of communication was reported to be the main factors affecting willingness to seek the help of a counselor, while lack of trust and stigma were the main factors contributing to reluctance. The respondents who were willing to seek help from an online chat stated however that accessibility and anonymity were primary factors. The majority who could not imagine seeking such online assistance stated lack of confidence and awareness as well as medium of communication as the foremost explanations. The study also showed that respondents are not only more willing to seek help for mental illness from a counselor than through online chat; they also have more experience in seeking this type of support. The factors that respondents felt to be positive and/or negative with their experience differed considerably from those factors that influenced the respondents' attitudes toward seeking help from a counselor or an online chat. Respondents drew attention to factors like the professionals' attitude and whether they received help with his or her problem as factors that characterized their experiences. Generally, however, the majority of respondents’ had positive experiences of seeking help from both counselors and online chats.

Le chat haret est l’un des prédateurs invasifs les plus dommageables pour la biodiversité insulaire. Sa présence est associée à une perte de biodiversité sur l’ensemble des îles sur lesquelles il est établi, et où il constitue une menace pour de nombreuses espèces de vertébrés souvent endémiques et menacés. En Nouvelle-Calédonie des populations de chats harets sont présentes dans tous les milieux et habitats et l’étude de son écologie et de ses impacts sur la faune ont fait l’objet de ce travail de thèse. L’analyse du régime alimentaire sur 14 sites d’études représentatifs des 4 habitats majeurs a révélé un régime très diversifié et une forte prédation sur les vertébrés natifs et notamment sur le groupe des scinques, des roussettes et des pétrels. Parmi les 44 espèces de vertébrés retrouvées dans le régime alimentaire de ce prédateur invasif, la plupart sont endémiques et 20 listées comme menacées sur la liste rouge mondiale de l’UICN. Le suivi des déplacements d’individus équipés de colliers GPS au niveau d’une presqu’île abritant une importante colonie d’oiseaux marins, a permis de mettre en évidence de grands domaines vitaux pour les mâles, des domaines vitaux petits pour les femelles et des patrons de déplacements liés aux différentes étapes du cycle reproducteur des oiseaux marins. Ces éléments, couplés aux analyses de régime alimentaire suggèrent une prédation à une large échelle géographique, à la fois sur les adultes reproducteurs mais également sur les jeunes oiseaux proches de l’envol. Une opération expérimentale de contrôle d’une population de chats harets a été conduite sur cette presqu’île et a montré une faible durabilité des effets de la suppression des individus sur les densités observées et une rapide recolonisation du site. Les résultats de ce travail plaident pour la mise en place de mesures de limitation des impacts occasionnés et permettent en particulier de cibler les habitats de maquis et forêt humide comme prioritaires en matière de limitation des abondances
Feral cat (Felis catus) is one of the most successful and harmful invasive predator species for island biodiversity. The presence of this alien predator species generally lead to dramatic loss of native island biodiversity and represents a serious threat for numerous endemic and threatened species. Feral cats have invaded the whole New-Caledonian archipelago and all its habitats. In this study, we focused on the ecology and impacts of this invasive predator on the outstanding endemic fauna found in the different habitats of the exceptional New-Caledonia biodiversity hotspot. Feral cat diet analyses on 14 selected sites representing the 4 main natural habitats revealed a high diversified diet and high predation rates on native species particularly on squamates, flying foxes and petrels. Among the 44 vertebrates species found into the feral cat diet, 20 are IUCN red-listed threatened species. Cat movements of eleven feral cats fitted with GPS collars have been studied in a western coast Peninsula hosting an important seabird colony. Male cats showed large home ranges while female showed small home ranges. Feral cats exhibited important movements within the studied peninsula linked with the breeding cycles of seabirds. GPS data coupled with dietary informations suggested a predation that concerned both breeding adults and fledgings bird, and at a large geographic scale as some feral cats have their core home range distant to the colony (>3km). We evaluated the effects of a high level but intense cat control on this site that showed a low sustainability of feral cat culling and a rapid recolonization process. Our results are pleading for the future limitation of feral cat impacts and call to focus first abundance limitation measures on maquis mosaic and humid forest habitats This study also provided information on the spatial extent and intensity of future control measures in the special context of a large and highly invaded island

Supply chain management (SCM) practitioners who ship temperature-sensitive diagnostic medical devices (DMDs) to clinicians must use effective cold chain management (CCM) strategies to avoid temperature excursions that contribute to medical device errors. Such errors have caused patient harm and death, which costs the U.S. health care system billions of dollars per year. The purpose of this qualitative multiple case study was to explore strategies for selecting and managing cold chain shipping solutions (CCSSs) requiring SCM executives to trade cost for regulatory compliance and predictability when mitigating temperature variations that occur during shipping. The conceptual framework for the study was the 6-change approaches, and its underpinnings that framed the exploration into the strategies some medical device executives use for shipping temperature-sensitive DMD tests and controls. Data were collected from in-depth interviews, field notes, and existing literature. The target population was 3 SCM executives working in California, New Jersey, and Ireland with at least 5 years of CCM experience in the medical device industry. A purposive sampling procedure guided the selection of participants for in-depth interviews. The data analysis included pattern matching techniques, central analysis, and collapse analysis. The results of this study indicated 3 successful strategies: validation of CCSSs, compliant shipping of DMDs, and CCM best practices. The study was socially significant because the findings may prevent medical device failures that have caused U.S. Food and Drug Administration recalls and patient harm.

In this case study a partnership between a first-tier supplier and a focal company in a Supply Chain has been examined. The focal company has a function as a wholesaler in the mechanical industry. An issue with communication and obstructions in the information flow between the two partners had caused problems in the material flow, which encompasses late deliveries and problems with the distribution between both partners has been treated in this case. These observations have resulted in recommendations for how employees in the focal company can work proactively with these issues linked to the first-tier supplier. The suggestions include application of Vendor managed inventory VMI between the customer and supplier company, including introduction of Lean methods in the focal company's operational activities. This to implement standardized routines for cleaning with 5S and Kaizen, with the purpose to handle the problems with late deliveries and reduce the risks of intermediate storage outcome in the inventory. At last another proposal for supplementation of the supplier base is formed, regarding the specific product group of strategic items where an acquisition risk prevails.
I denna fallstudie har ett partnerskapsförhållande mellan en primärleverantör och en fokalfirma – med funktion som grossist inom maskinindustrin utvärderats. Problematik med kommunikation och bristande informationsflöde som förorsakat ett bristande materialflöde i form av sena leveranser i distributionen mellan parterna har behandlats. Dessa observationer har i senare led resulterat i rekommendationer och tillvägagångssätt för hur ansvariga i fokalfirman kan arbeta proaktivt kring detta och återkoppla till primärleverantören. Därefter har en rad förslag till förbättringsåtgärder framställts.Förslagen innefattar införande av VMI-styrning mellan kund- och leverantörsföretaget för att åstadkomma en starkare integration i informationsflödet mellan parterna. Detta i kombination med införande av Lean metoder i fokalfirmans operativa aktiviteter på lagret, för att introducera standardiserade rutiner kring städning med 5S och Kaizen-moral. På så sätt ska sena inleveranser på lagret effektivare kunna behandlas och risken för uppkomst av mellanlager på verkstadsgolv reduceras. Slutligen har ett ytterligare förslag tagits fram som en alternativ lösning och det är att uttöka leverantörsbasen. Genom uttökningen underbyggs anskaffningsrisken gällande en specifik produktgrupp med strategiska artiklar ur företagets produktsortiment.

Bakgrund/problem: Företag blir alltmer utsatta av tryck från intressenter att de ska agera hållbart vid inköp och därmed ökar kraven på att leverantörer ska följa företags code of conduct. Code of conduct är företagets formulering av strategiska risker som ska undvikas. Strategiska risker är beroende av företagets affärsstrategi och intressenter. Företag måste övervaka att code of conduct följs av leverantörer, annars utsätts företag för risken att deras rykte och värdeskapande förmåga försämras. Inköpsprocessens olika steg är sammankopplade och beroende av beslut som tagits i tidigare steg. Syfte: Vårt syfte var att utvärdera hur Andritz hanterar strategiska risker i deras inköpsprocess gentemot deras leverantörer samt ge förslag på hur Andritz kan förbättra hanteringen av strategiska risker i inköpsprocessen. Metod: Vår forskningsansats var en fallstudie med utvärderingsdesign. Insamling av material har samlats in genom företagsdokument och intervjuer utifrån målstyrt urval. Resultat/Slutsats: Andritz hanterar de ekonomiska riskerna; kvalitet och pris. Det finns förbättringar som Andritz kan göra med sociala och miljörisker. Andritz har tillskillnad från kvalitet och pris, inte specificerat vad de vill få ut av leverantören med arbetsmiljö, arbetssäkerhet, avfall och utsläpp. Andritz behöver tydligt specificera vad de vill få ut av leverantörer samt skapa rutiner för hur kontroller ska genomföras.
Background / problem: Companies have experienced an increased pressure from stakeholders to act more sustainable in their purchasing and therefor costumer demands of supplier compliance of code of conduct have increased. Code of conduct is a way for companies to manage strategic risks, which depends on the business strategy and stakeholders. Companies must monitor supplier’s compliance of code of conduct; otherwise the company will be exposed to the risk of reputational damage and decreased value creation. The different steps in the purchasing process are connected and dependent on decisions that have been made in the previously steps Purpose: Our purpose was to evaluate how Andritz manage strategic risks in purchasing process in relationship to their suppliers, in order to bring suggestions of improvements that Andritz can make to improve the strategic risk management in the purchasing process. Method: Our research approach is an evaluation case study. Collection of data has been collected through business documents and interviews based on target-oriented selection. Results / Conclusion: Our conclusion is that Andritz manage their economic risks as quality and low cost, but improvement can be made when it comes to social and environment risks. Andritz have not specified what they want from the suppliers when it comes to work safety, waste and emission and working environment, and because of the lack of clear social and environmental terms, Andritz have to create specifications of what they want of the supplier’s and also create routines of how controls will be carried out.

Background: Today's markets have over time tended to become more global, which in turn has increased competition between companies. This has meant that many industry organizations have had to change in order to be competitive in the market. A concept that today permeates many companies is the lean practice, which is based on maximizing the use of resources, eliminating waste, and creating more efficient production. By working with lean, companies can achieve faster throughput time. For manufacturing industrial companies, a reduction in throughput time can generate various benefits. Some of these advantages are: reduced number of products in work, better quality, reduced costs, better forecasts, increased flexibility and reduced lead time towards customers.Press Kogyo has for a long period experienced problems with one of their processes. The main problem has been that they do not know what non-value-added activities/waste that can be found in the process and how these activitiesaffect the total throughput time of the process. Purpose: The purpose of the study is to map Press Kogyo's propeller process in order to be able to identify non-value-adding activities in the process. Furthermore, the study will provide Press Kogyo with proposals regarding how more efficient material and production control can reduce the throughput time in the propeller process. In order for the study to achieve theoretical relevance, another purpose of the study is to contribute with theories about how manufacturing companies, with a functional layout, can reduce the disadvantages of the layout with more efficient material and production control. Methodology: The study has been divided into three research questions. The first two research questions were specifically aimed at Press Kogyo, while the third research question was more generally directed at manufacturing companies with a functional layout. The study was conducted as a case study and was characterized by qualitative research methods. Empirical data has been collected through interviews, observations, and a focus group. For the first research question, process maps and VSM maps were created. This together with various interviews created the foundation for identifying non-value-adding activities/waste in the propeller process which affected the throughput time. For research question two, theory of material and production control was applied in order to reduce the non-value-adding activities/waste and consequently reduce throughput time in the process. Regarding research question three, interviews were conducted with Press Kogyo and another manufacturing company with a functional layout. The authors intended to, through these interviews, find answers to how manufacturing companies with a functional layout can reduce the disadvantages of the layout with the help of efficient material and production control. Conclusions: In the study, seven wastes were identified where “wait” was considered to be the waste that affected throughput time the most in the propeller process. To eliminate all waste and specifically the waste “wait”, methods and theories regarding material and production control was applied with a focus on production activity control (PAC). All the different theories that was used also created a theoretical model which can be a good basis for planning when companies with a functional layout want to find ways tostreamline their planning. Some parts of the theoretical model were also used later in the study where it was used to reduce the disadvantages that may exist with a functional layout

Abstract Medium access control (MAC) in wireless ad hoc networks has received considerable attention for almost a couple of decades; however, there are still open problems which deserve thorough study in order to facilitate migration to the next generation broadband wireless communication systems. In ad hoc networks, a detected frame collision can be due to the so-called unreachability problem, where the destination station is situated either in the transmission or interference range of an emitting station and is unable to receive connection establishment frames from any of its neighboring stations. Unreachability might also be due to the inability of a radio station to respond to any connection establishment request, though when the unreachable station receives the connection establishment requests, however, it is prohibited from responding to the requests due to being situated in the interference range of the emitting neighbor. To investigate the impact of this problem, we have to be equipped with a proper analytical framework; therefore, as the first part of this thesis, a scalable framework called Parallel Space – Time Markov chain (PSTMC) is proposed, through which a finite load non-saturated ad hoc network can be easily modeled. At the first step, a single-hop ad hoc network is considered and the accuracy of the model is evaluated using extensive numerical results. Subsequently, the proposed framework is further extended to model multi-hop ad hoc networks. Several discussions are also given on how the framework can be deployed for an arbitrary network topology. One of the main key features of the PSTMC model is its remarkable scalability in modeling complex network configurations. In fact, it is shown that multi-hop ad hoc networks have bounded complexity in being modeled by the PSTMC framework due to its spectacular specifications. These features lead us to a powerful tool by which an arbitrary network topology can be studied. In addition, the proposed models clearly facilitate demonstrating the impact of the unreachability problem on the performance of multi-hop networks. The introduced framework shows how the unreachability problem degrades the achieved throughput and channel capacity by the contending radio stations depending on the deployed network topology. In the remainder of the thesis the unreachability problem in mobile ad hoc networks is tackled and a new MAC protocol to enhance the performance of the network is proposed. This MAC scheme is equipped with smart decision-making algorithms as well as adaptive management mechanisms to reduce the impact of the unreachability problem in single channel scenarios. Subsequently, the problem of concurrent radio resource management and contention resolution in multi-channel cognitive ad hoc networks is considered. In particular, a multi-channel technique for traffic distribution among a set of data channels without centralized control, which is enabled by a probabilistic channel selection algorithm as well as a multi-channel binary exponential backoff mechanism, is proposed. It is shown through simulations that the suggested scheme outperforms the existing MAC protocols in multi-channel environments as well as cognitive networks coexisting with primary users. A mathematical model is also introduced to study the performance of the multi-channel MAC protocol in a single-hop non-saturated wireless network.

Annotation:

In this thesis, we consider optimal control problems arising in high-speed integrated communication networks with Quality of Service (QOS) constraints. Integrated networks are expected to carry a large variety of traffic sources with widely varying traffic characteristics and performance requirements. Broadly, the traffic sources fall into two categories: (a) real-time sources with specified performance criteria, like small end to end delay and loss probability (sources of this type are referred to as Type 1 sources below), and (b) sources that do not have stringent performance criteria and do not demand performance guarantees from the network - the so-called Best Effort Type sources (these are referred to as Type 2 sources below). From the network's point of view, Type 2 sources are much more "controllable" than Type 1 sources, in the sense that the Type 2 sources can be dynamically slowed down, stopped or speeded up depending on traffic congestion in the network, while for Type 1 sources, the only control action available in case of congestion is packet dropping. Carrying sources of both types in the same network concurrently while meeting the performance objectives of Type 1 sources is a challenge and raises the question of equitable sharing of resources. The objective is to carry as much Type 2 traffic as possible without sacrificing the performance requirements of Type 1 traffic. We consider simple models that capture this situation. Consider a network node through which two connections pass, one each of Types 1 and 2. One would like to maximize the throughput of the Type 2 connection while ensuring that the Type 1 connection's performance objectives are met. This can be set up as a constrained optimization problem that, however, is very hard to solve. We introduce a parameter b that represents the "cost" of buffer occupancy by Type 2 traffic. Since buffer space is limited and shared, a queued Type 2 packet means that a buffer position is not available for storing a Type 1 packet; to discourage the Type 2 connection from hogging the buffer, the cost parameter b is introduced, while a reward for each Type 2 packet coming into the buffer encourages the Type 2 connection to transmit at a high rate. Using standard on-off models for the Type 1 sources, we show how values can be assigned to the parameter b; the value depends on the characteristics of the Type 1 connection passing through the node, i.e., whether it is a Variable Bit Rate (VBR) video connection or a Continuous Bit Rate (CBR) connection etc. Our approach gives concrete networking significance to the parameter b, which has long been considered as an abstract parameter in reward-penalty formulations of flow control problems (for example, [Stidham '85]). Having seen how to assign values to b, we focus on the Type 2 connection next. Since Type 2 connections do not have strict performance requirements, it is possible to defer transmitting a Type 2 packet, if the conditions downstream so warrant. This leads to the question: what is the "best" transmission policy for Type 2 packets? Decisions to transmit or not must be based on congestion conditions downstream; however, the network state that is available at any instant gives information that is old, since feedback latency is an inherent feature of high speed networks. Thus the problem is to identify the best transmission policy under delayed feedback information. We study this problem in the framework of Markov Decision Theory. With appropriate assumptions on the arrivals, service times and scheduling discipline at a network node, we formulate our problem as a Partially Observable Controlled Markov Chain (PO-CMC). We then give an equivalent formulation of the problem in terms of a Completely Observable Controlled Markov Chain (CO-CMC) that is easier to deal with., Using Dynamic Programming and Value Iteration, we identify structural properties of an optimal transmission policy when the delay in obtaining feedback information is one time slot. For both discounted and average cost criteria, we show that the optimal policy has a two-threshold structure, with the threshold on the observed queue length depending, on whether a Type 2 packet was transmitted in the last slot or not. For an observation delay k > 2, the Value Iteration technique does not yield results. We use the structure of the problem to provide computable upper and lower bounds to the optimal value function. A study of these bounds yields information about the structure of the optimal policy for this problem. We show that for appropriate values of the parameters of the problem, depending on the number of transmissions in the last k steps, there is an "upper cut off" number which is a value such that if the observed queue length is greater than or equal to this number, the optimal action is to not transmit. Since the number of transmissions in the last k steps is between 0 and A: both inclusive, we have a stack of (k+1) upper cut off values. We conjecture that these (k + l) values axe thresholds and the optimal policy for this problem has a (k + l)-threshold structure. So far it has been assumed that the parameters of the problem are known at the transmission control point. In reality, this is usually not known and changes over time. Thus, one needs an adaptive transmission policy that keeps track of and adjusts to changing network conditions. We show that the information structure in our problem admits a simple adaptive policy that performs reasonably well in a quasi-static traffic environment. Up to this point, the models we have studied correspond to a single hop in a virtual connection. We consider the multiple hop problem next. A basic matter of interest here is whether one should have end to end or hop by hop controls. We develop a sample path approach to answer this question. It turns out that depending on the relative values of the b parameter in the transmitting node and its downstream neighbour, sometimes end to end controls are preferable while at other times hop by hop controls are preferable. Finally, we consider a routing problem in a high speed network where feedback information is delayed, as usual. As before, we formulate the problem in the framework of Markov Decision Theory and apply Value Iteration to deduce structural properties of an optimal control policy. We show that for both discounted and average cost criteria, the optimal policy for an observation delay of one slot is Join the Shortest Expected Queue (JSEQ) - a natural and intuitively satisfactory extension of the well-known Join the Shortest Queue (JSQ) policy that is optimal when there is no feedback delay (see, for example, [Weber 78]). However, for an observation delay of more than one slot, we show that the JSEQ policy is not optimal. Determining the structure of the optimal policy for a delay k>2 appears to be very difficult using the Value Iteration approach; we explore some likely policies by simulation.

La pratique du rituel de possession de hầu bóng au Vietnam a connu une période d’interdiction pendant plus de quarante ans (de 1954 au début des années quatre-vingt-dix). Ces travaux, basés sur des études sur le terrain réalisées à la fin de cette période d’interdiction tentent d’abord de faire une description détaillée du rituel et l’état des lieux de ses cung văn «maîtres musiciens» à travers l’étude du répertoire du plus grand maître, Pham Van Kiêm. Ils proposent d’explorer ensuite les questions techniques utilisées par les maîtres musiciens et leur rôle par rapport à la pratique du rituel ainsi que les liaisons entre paroles et musique, entre le répertoire musical et le panthéon des génies. Ce témoignage de cette période cruciale permet, par le biais de la musique, de mettre en perspective une pratique religieuse bien complexe en plein essor à ce jour
The possession ritual practice in Vietnam has been prohibited during more than forty years (from 1954 to early nineties). The field-works are done during this important period. These studies try to portray an outline of the organisation and development of the rite and its music and musicians, especially the most important master at his time, Pham Van Kiêm. They also try to explore the musical technics used by masters and their role in the ritual practice, the music-language, musical directory-deities pantheon relationships.

A travers cette recherche, nous souhaitons identifier et définir le genre duroman utopique de la fin des Qing via la lecture attentive d'une sélection deromans chinois écrits entre 1902 et 1910. A partir de l'analyse de romans telsque Xin Zhongguo weilai ji de Liang Qichao (1902 ), Shizi hou de Chen Tianhua(1905), Xin shitou ji de Wu Jianren (1908) et Xin Zhongguo de Lu Shi'e(1910), nous pensons qu'un tel genre littéraire puisse être considéré à la foiscomme un produit particulier du climat de fragmentation socio-historique quicaractérise la période de la fin des Qing, et comme un prisme utile à sacompréhension. La structure de cette thèse est celle d'un itinéraire critique àtravers l’imaginaire utopique chinois moderne. Cet itinéraire est débuté par latraduction de l’histoire courte Xinnian Meng, écrite par Cai Yuanpei en 1905. Lecorps de cette recherche est divisé en cinq chapitres: dans le premier, lalégitimité de la catégorie générique de "wutuobang xiaoshuo" comme outilcritique valable est questionnee; le deuxième chapitre concerne les deuxromans inachevés de Liang Qichao et Chen Tianhua, dont l'étatd’«incomplétude» est utilisé comme métaphore pour la compréhension de laconstruction utopique; le troisième chapitre touche à la relation entre le romanutopique de la fin des Qing et ses modèles étrangers; enfin, dans les deuxderniers chapitres, les éléments critiques développés dans les sectionsprécédentes de la thèse sont appliqués à la lecture attentive de Xin shitou ji deWu Jianren et de Xin Zhongguo de Lu Shi'e, deux des romans les plusintéressants écrits durant cette période
With this research it is our intention to identify and define the genre of the lateQing utopian novel from the close reading of a selection of Chinese novelswritten between 1902 and 1910. With the analysis of novels such as LiangQichao's Xin Zhongguo weilai ji (1902), Chen Tianhua's Shizi hou (1905), WuJianren's Xin shitou ji (1908) and Lu Shi'e's Xin Zhongguo (1910), we believethat such a literary genre can be considered both as a peculiar product of theclimate of socio-historical fragmentation that characterises the late Qingperiod, and as a useful lens for its understanding. The structure of this thesis isthat of a critical itinerary within the Chinese modern utopian imaginary. Thisitinerary is introduced by the translation of the short story Xinnian meng,written by Cai Yuanpei in 1905. The body of this research is divided into fivechapters: in the first one, the legitimacy of the generic category of “wutuobangxiaoshuo” as a viable critical tool is put under question; the second chapterconcerns the two unfinished novels by Liang Qichao and Chen Tianhua, whosecondition of “incompleteness” is adopted as metaphor for the understanding ofthe utopian construct; the third chapter concerns the relation between the lateQing utopian novel and its foreign models; while in the last two chapters, thecritical framework developed in previous sections of the thesis is applied to theclose reading of Wu Jianren's Xin shitou ji and Lu Shi'e's Xin Zhongguo, two ofthe most interesting novels written in this period

State of movement, is not limited to human's physical body motion in the space, but also the changes of mind and objects. The phenomena of changes in space, environment, migration of animals and plants, has been continuously happens. Some of the changes are voluntarily, some are not. But most of them will experience certain degree of impact in culture and life. The impact of state of movement is not only results changes in physical body, but also affects the state of mind and soul. The title of this thesis is named as "The movement of body and mind". The creation of "The movement in of body and mind" is describing the changes in scene and emotion during the journey of movement. Using the method of painting, it is reflecting the state of movement experienced from vision, integrated with the human kind's inner feeling of mind and soul. In this constantly changing world, when people are continuously moving, may our heart can find a peace of mind and a place of where it belongs to.

The retail businesses in Taiwan, like retail chain stores, and local franchise brand restaurants all intend to find out a set of rules which let the executives know how to expand their store, and how to increase incomes of each franchised store, the accumulated large amounts of data collected by each store, but these data relative lack of business intelligence analysis, these may become the bottlenecks of retail business development. In this study, the freeware R is introduced, with association rules, we wish to find the correlation between commodities pick up by customers visiting two retails hot-pot restaurant in a same designated season, in addition; this research will try to find out if the amount of sales will be effected by changing temperature and also the key ingredients ranking the most profitable items in this chain store menu will be focused. Among analysis results, we find that consumers in Changhua area who have a feature of sharing meal which is ranked as most valuable, its value of support is 0.091, the value of confidence is 0.518, and the value of lift is 1.314, and comparing data collected in two different areas, such as: pasta preference, consumers come from Taichung prefer instant noodles, but customers come from Changhua prefer Udon. The data analysis results can offer the executives, it shows variety of marketing programs to attract different consumers, and promote the customer's desire for consumption, and enhance the turnover of hot-pot chain restaurant. The result also allows both parties to communicate with suppliers, make adjustments to allow sales to maximize profits, minimize holding costs.

In recent years, the Taiwan government actively formulates legislations to facilitate effective management and sustainable use of hot spring resources. However, due to the trend of market internationalization and industry globalization, product competition not only exists between enterprises but also rivals between the overall supply chain. Therefore, the integration supply chain for hot spring industry has become an inevitable trend. In order to establish a comprehensive framework for the hot spring supply chain industry, this thesis applies the supply chain theory to hot spring industries, and draws the prototype diagram for the hot spring supply chain industry based on the literature survey, and then further revises the diagram according to the interview with the industry/government/academic experts in hot spring-related fields. Based on the proposed spa-related supply chain architecture, readers can clearly understand the utilization of hot spring not only limited to bathing, washing, tourism, etc., but also can have more diversified, high value-added applications. The results investigated by this work can serve as the foundation for further exploration of the spa industry value. Also, they provides multi-dimensional information to industry investors and government decision-makers who plan to invest and are in charge to manage hot spring related industries, respectively.

This study focuses on media discourses and the construction of nationalism,through analyzing how mainstream newspapers and Tangwai magazines (黨外雜誌) report “Hou Dejian’s return to China in 1983”. In order to highlight different political tendency of news, ideology, and social context through media’s discourses, this study apples Fairclough’s three levels of social analysis: social events, social practices, and social structures. The thesis suggests that their representation of this event was various due to the unequal degree of political control between mainstream newspapers and Tangwai magazines in the period of martial law. At the beginning of this event, mainstream newspapers generally understated Hou’s return. They tended to personalize the motivation of Hou’s return, and avoided mentioning the complex of his national identity. Still some “different” media discourses between newspapers, walks on the edge of government’s sensitive nerve. On the contrary, Tangwai magazines used a lot of space to discuss Hou’s national identity complex, and the complex resulted in the complicated emotions of national identity between Chinese Consciousness (中國意識) and Taiwanese Consciousness (台灣意識). These show the particularity of the construction of Taiwanese Consciousness in 1980s.

We present a Markov chain analysis for studying the performance of wireless ad hoc networks. The models presented in this dissertation support an arbitrary backoff strategy. We found that the most important parameter affecting the performance of binary exponential backoff is the initial backoff window size. Our experimental results show that the probability of collision can be reduced when the initial backoff window size equals the number of terminals. Thus, the throughput of the system increases and, at the same time, the delay to transmit the frame is reduced. In our second contribution, we present a new analytical model of a Medium Access Control (MAC) layer for wireless ad hoc networks that takes into account frame retry limits for a four-way handshaking mechanism. This model offers flexibility to address some design issues such as the effects of traffic parameters as well as possible improvements for wireless ad hoc networks. It effectively captures important network performance characteristics such as throughput, channel utilization, delay, and average energy. Under this analytical framework, we evaluate the effect of the Request-to-Send (RTS) state on unsuccessful transmission probability and its effect on performance particularly when the hidden terminal problem is dominant, the traffic is heavy, or the data frame length is very large. By using our proposed model, we show that the probability of collision can be reduced when using a Request-to-Send/Clear- to-Send (RTS/CTS) mechanism. Thus, the throughput increases and, at the same time, the delay and the average energy to transmit the frame decrease. In our third contribution, we present a new analytical model of a MAC layer for wireless ad hoc networks that takes into account channel bit errors and frame retry limits for a two-way handshaking mechanism. This model offers flexibility to address design issues such as the effects of traffic parameters and possible improvements for wireless ad hoc networks. We illustrate that an important parameter affecting the performance of binary exponential backoff is the initial backoff window size. We show that for a low bit error rate (BER) the throughput increases and, at the same time, the delay and the average energy to transmit the frame decrease. Results show also that the negative acknowledgment-based (NAK-based) model proves more useful for a high BER. In our fourth contribution, we present a new analytical model of a MAC layer for wireless ad hoc networks that takes into account Quality of Service (QoS) of the MAC layer for a two-way handshaking mechanism. The model includes a high priority traffic class (class 1) and a low priority traffic class (class 2). Extension of the model to more QoS levels is easily accomplished. We illustrate an important parameter affecting the performance of an Arbitration InterFrame Space (AIFS) and small backoff window size limits. They cause the frame to start contending the channel earlier and to complete the backoff sooner. As a result, the probability of sending the frame increases. Under this analytical framework, we evaluate the effect of QoS on successful transmission probability and its effect on performance, particularly when high priority traffic is dominant.

The economic is up and down over the world for years. Despite of the financial crisis, nobody can stop getting food. Eating is human’s needs and eating-out is a new trend of industrial society nowadays. Under a stable economy, people are not only need to eat but also need an exquisite eating. Recently, eating-out is like an art of diet for Taiwanese, and being a diet cultural performance. It makes diet to be diversification. Especially in the case of making a well lifestyle, everybody will pay attention to diet on. In the past few years, the local of traditional Taiwanese food has changed, and a lot of international food has been coming from over the world, including the United State, European, Asian, Italian, tropical regions food, or Mediterranean cuisine…we can enjoy all in Taiwan. In hotpot industry, after years of development, it has taken a business model. And it has a chain of production system, especially franchise business. They have taken a unified lot size orders and delivery to reduce the cost. Besides, because of the acute competition, the owners have to pay more attention to the reaction of customers to revise business model. They have finished a systematic management. The goal of the study is to examine customer satisfaction and performance by a case study from hotpot industry. Based on the questionnaire results, the impacts of customer satisfaction and royalty on the performance are explored. The thesis also analysis the cost structures and revenues of the case firm. The results show that the customer satisfaction and consumption frequency is related to customer royalty. Higher satisfaction, higher consumption frequency and royalty are. Based on the cost structure of hotpot, company should pay more attentions, when making marketing strategies, on the hotpot with higher contribution margin in order to earn more profits. Key words: customer satisfaction, customer royalty, control cost efficiencies

More and more people in Taiwan are inclined to eat out. The top four markets for eating out are street vendors, cafeterias, fast food stores, and hot pot restaurants. In Taiwan, the most popular chain store is a hot pot restaurant. There are over 900 hot pot restaurants in Taiwan. The total number of hot pot restaurants is even more than that of the Japanese or Korean food restaurants. The business of hot pots in Taiwan is really full of competitiveness. The study is to understand what factors of high revenue and high market share of hot pot restaurants are. The study also wants to know whether the factors mentioned above are related to the condition—the high service quality or customer satisfaction leads to high customer loyalty. The results of the study can offer the hot pot restaurant owners a consultation to run their business. When customers choose a hot pot restaurant, they can consult the results of the study. According to the literature review and scholar interview, the researcher extracts three major rules and nine minor rules as the first step. Second, the researcher gives out the questionnaires and applies AHP (Analytic Hierarchy Process) to quantify weight values and rank order of architectural planning factors. Finally, get the conclusion—the main factors of why customers choose the hot pot restaurant to consume, and what factors they will attach importance to. The research results are expected to clarify and confirm the relationship among the three major rules—the image of chain restaurants, the rules of the prices, and the environment and characteristic of the restaurants . The research results are also expected to know the weight values among the nine minor rules—the reason of joining an alliance, public reputation, regular customers, the rules of chain restaurants, distinguishing features of foodstuffs, customer positioning, the convenience of traffic and parking, the ambience of the restaurant environment, and well-trained employees.

A mobile ad-hoc network (MANET) is a characteristized by multi-hop wireless links, in the absence of any cellular infrastructure, as well as frequent host mobility. This paper proposes a TDMA-based routing using hexagonal-chain for a wireless mobile ad-hoc networks. One major contribution of this paper is to identify a special routing structure, namely hexagonal-chain, under taking both hidden-terminal and exposed-terminal problems into consideration. Existing solutions have addressed this problem by assuming a stronger multi-antenna model, where the bandwidth of a link is independent of the transmitting/receiving activities of its neighboring links, or a less stronger CDMA-over-TDMA channel model, where the use of a time slot on a link is only dependent on the status of its one-hop neighboring links. The proposed approach increases the robustness of a route lies in identifying backup paths on hexagonal-chain under the TDMA channel model from source host to destination host, in a MANET to satisfy certain bandwidth requirement. Performance analysis results is finally demonstrated.

After the government declared that the martial law had ended, Taiwanese art became to get rid of the burden of politics and tradion and start to wear a gorgeous face gradually. New visual aesthetics which break tradional/academic representations of human bodies have gradually come into extistence.This thesis pays attention to the change, and fouses on two convulsive series of works: Hou Jun-Ming’s Sou Shen Ji and Chen Jie-Ren’s Hun Po Bao Luan. It will deeply discuss the relationship between Taiwanese art and social atmosphere by interpreting the specific bodily images of the two series of works. The main point of writing this thesis is mainly “transgression”. It attempts to analyze how Sou Shen Ji and Hun Po Bao Luan bear the artists’ recations, critical thoughts and re-interpretation against the traditional society and national power in social open atmosphere. Furthermore, I think that these two series of works have the Bataillean transgression aesthetics no matter how their forms and contents are heterogeneous. Morever, I also want to indicate these bodily images of these two series of works have grotesque characteristics, and try to analyze politics meanings of these grotesque bodily images. Lastly, I also seek to figure out how these works reflect the artists’ anxiety and desire by referring to some articles and interviews of artists intertextualily. In conclusion, I will explain the synchronic meanings of these bodily images in Taiwanese art.

The most popular chain restaurant in Taiwan is the hot pot restaurant. As the major food and beverage groups have entered the hot pot market, the personal small hot pot “shubu shubu” restaurant is facing a big challenge due to its scale of operation, brand image and limited resources. This study explores the key success factors for the facet of the business model of hot pot restaurant chain operators. In addition to the successful business model, the value of modern enterprises depends on the brand, resources and capabilities of the company itself. Brand is a self-recognition hidden in the hearts of consumers. Brand management needs to consider many aspects in order to grasp the key elements of creating value and successful brand. The purpose of this study is to explore the business model of the hot pot chain restaurant industry and finding out the key success factors of the enterprise to create a competitive advantage, and create profits. This study uses case interviews, data analysis and literature review to make some practical suggestions for relevant industries.
