Last chance tourism (LCT) is defined as an endangered place due to climate change which creates motivations for tourists to travel to these places before they vanish. These trips also involve interaction with and observation of rare species that is about to disappear due to climate change. By integrating the Value-Belief-Norm and cognitive dissonance theory models, the main purpose of this research was to investigate psychological antecedents of engaging in LCT in higher educational institutions in Sweden. A survey was administered to 234 academics on seven universities in Sweden consisting of items measuring beliefs, pro-environmental personal norms, cognitive dissonance, and intentions to engage in Last Chance Tourism. The data was later analyzed using Partial Least Square-Structural Equation (PLS-SEM) approach. The results revealed a significant impact of cognitive dissonance on intentions to engage in LCT. These findings are important since they support the advantage of using cognitive dissonance theory within the context of LCT. The implications will hopefully spark an interest among academics to develop a sustainable tourism rescue plan and transfer this knowledge to a younger generation. For practitioners, this could be food for fought for organizations that are operating within the field of LCT.

The purpose of this work was to investigate how a last mile-transport vehicle can be constructed around a shoe. The prototype, which is controlled without a handheld controller, was designed to propel an adult forward with the use of an electric driveline. The user can easily stop driving, and instead walk short distances without removing the prototype. Research questions have been answered regarding how the battery and motor can be configured to reach a top speedof 15 km/h and a range of 3 km. In addition, answers were given as to how a user should control the vehicle’s speed in a safe and simple way, without the use of a handheld remote controller. The results show that the prototype reaches the specified top speed, and that the specified range is reached and exceeded. The user controls the motor power by moving their weight from the left to the right foot. The applied weight is measured by load cells under the heel, and after calibration, this user input method can be seen as satisfactory. The electric driveline, which is mounted under the shoe, allows the user to walk short distances without removing the prototype. Future work may add safety equipment such as lamps and a bell to make the product legal for use in public areas. In addition, a left shoe needs to be developed further, due to how the concept is dependent on it to function optimally. / Det här arbetet hade till avsikt att undersöka hur ett sistasträckan-fordon kan konstrueras kring en sko. Prototypen, vilken styrs utan en handkontroller, utformades för att förflytta en vuxen person med hjälp av en elektrisk drivlina. Användaren kan enkelt sluta åka, och istället gå kortare sträckor utan att ta av sig prototypen. Forskningsfrågor har besvarats angående hur batteri och motor kan konfigureras för att uppnå topphastigheten 15km/h och färdsträckan 3 km. Dessutom besvarades hur en användare ska kontrollera fordonets hastighet på ett säkert och enkelt sätt, utan användning av en handkontroll. Resultaten visar att prototypen uppnår topphastigheten, och att den angivna räckvidden uppnås och överskrids. Användaren styr motoreffekten genom att förflytta sin vikt från vänster till höger fot. Den applicerade vikten mäts av lastceller under hälen, och efter kalibrering kan denna användar-inmatningsmetod ses som tillfredsställande. Den elektriska drivlinan, som monteras under skon, tillåter att användaren går kortare sträckor utan att ta av sig prototypen. Framtida arbete kan tillägga säkerhetsutrustning, som lampor och ringklocka för att göra produkten laglig för användning på allmän plats. Dessutom behöver en vänstersko utvecklas mer, på grund av hur konceptet är beroende av denna för att fungera optimalt.

Electrification of the transport sector is an important step in reducing the global greenhouse gas (GHG) emissions. Compared to traditional internal combustion engine vehicles (ICEVs), electric vehicles (EVs) produce no tail-pipe emissions and could be coupled with responsible energy production from renewable energy sources to reduce coupled emissions of their operation. One particularly interesting segment of the transport sector is the light-duty trucks (LDTs) commonly utilized in last-mile distribution. These vehicles are responsible for the third largest GHG-emissions in the road transportation sector in Sweden and is not as detailly covered in existing research compared to heavy-duty and passenger vehicles. At the same time usage of these vehicles is increasing due to the rapid increase of e-commerce. The objective of this thesis therefore is to investigate the potential of electrification for LDTs in last-mile distribution, operating in Stockholm, Sweden. The study is conducted through a techno economical optimization along with a business model innovation coupled to the current last mile operation of three collaborating partner companies. In this way, real world cases are included in the study to reflect on the feasibility of electrification of these vehicles. Conclusions of the study shows that electrification of the LDTs in last-mile operation in Stockholm, Sweden is possible. However, it would require value-adding measures to gain economic profit when transitioning from ICEVs. In addition, there also exists practical challenges as there is a significant need for route charging for several vehicles in the analyzed company fleets. This implies that operational driving behavior is required to be reviewed to reduce the requirement of route charging. Additionally, there is a need for investigating how route charging could be supplied to the companies. / Elektrifiering av transportsektorn är ett viktigt steg för att minska de globala utsläppen av växthusgaser (GHG). Jämfört med traditionella fordon med förbränningsmotorer (ICEVs) ger elfordon (EVs) inga direkta avgasutsläpp och skulle kunna kopplas till ansvarsfull energiproduktion från förnybara energikällor för att minska de kopplade utsläppen från deras drift. Ett särskilt intressant segment av transportsektorn är de lätta lastbilarna (LDTs) som vanligtvis används i last-mile distribution. Dessa fordon är ansvariga för de tredje största utsläppen av växthusgaser inom vägtransportsektorn i Sverige och täcks inte lika ingående i befintlig forskning jämfört med tunga fordon och personbilar. Samtidigt ökar användningen av dessa fordon på grund av den snabba ökningen av e-handel. Syftet med denna avhandling är därför att undersöka potentialen för elektrifiering för LDTs i last-mile distribution, verksamma i Stockholm, Sverige. Studien genomförs genom en tekno-ekonomisk optimering tillsammans med en affärsmodellinnovation kopplad till den nuvarande verksamheten hos tre deltagande partnerföretag. På så sätt inkluderas verkliga fall i studien för att reflektera över genomförbarheten av elektrifiering av dessa fordon. Slutsatser av studien visar att elektrifiering av LDTs inom last-mile distribution i Stockholm, Sverige är möjlig. Det skulle dock kräva värdeskapande åtgärder för att få ekonomisk vinst vid övergången från ICEVs. Dessutom finns det praktiska utmaningar i och med ett stort behov av ruttladdning för flera fordon i de analyserade företagsflottan. Detta innebär att det operativa körbeteendet måste ses över för att minska kravet på ruttladdning. Dessutom finns ett behov av att undersöka hur ruttladdning på bästa sätt skulle kunna tillföras företagen.

E-handel har de senaste åren ständigt ökat vilket har bidragit till ökande krav på hållbaratransporter vilket medverkat till forskning av alternativ till traditionella transportföretag.Crowdshipping är ett koncept där det med hjälp av teknologiska applikationer kan utnyttjaindividers resurser för att skapa transportnätverk inom urbana områden. Användandet avindivider som redan är på väg till en plats och tar med ett paket i farten kan innebära mindrefordon på vägarna. I denna studie samlade vi in empirisk data genom att skicka ut en enkät till olika facebook-grupper bestående av studenter i Sverige och utförde två fokusgrupper med totalt åtta deltagare. Syftet med enkäten och fokusgrupperna var att undersöka respondenternasinställning och uppfattade hinder/möjligheter till crowdshipping. Med kunskap samlat utifrånvetenskapliga artiklar kunde ett teoretiskt ramverk etableras. Genom att studerat väsentligafaktorer till crowdshipping (tillit och säkerhet, miljö och hållbarhet, tid ochkompensation/prissättning) kunde vi analysera vårt empiriska material. Analysen byggs uppefter de teoretiska faktorerna som har inverkan på crowdshipping. Det visade sig attrespondenterna hade bekymmer med flertal säkerhetsaspekter inom CS-initiativ sompåverkade deras inställning negativt. Dock ansåg många respondenter initiativet som positivtifall det gick att säkerställa miljömässiga fördelar och flertalet säkerhetsaspektertillhandahölls. / E-commerce has steadily increased in recent years, which has contributed to increaseddemands for sustainable transport, which contributes to research into alternatives totraditional transport companies. Crowdshipping is a concept where, with the help oftechnological applications, it can utilize individuals' resources to create transport networks inurban areas. The use of individuals who are already on their way to a place and taking apackage on the go can mean fewer vehicles on the roads. In this study, we collected empirical data by sending out a questionnaire to various Facebookgroups consisting of students in Sweden and conducted two focus groups with a total of eightparticipants. The purpose of the survey and focus groups was to examine the respondents'attitudes and perceived obstacles/opportunities for crowdshipping. With knowledge gatheredbased on scientific articles, a theoretical framework could be established. By studyingsignificant factors for crowdshipping (trust and security, environment and sustainability, timeand compensation/pricing), we were able to analyze our empirical material. The analysis isbased on the theoretical factors that have an impact on crowdshipping. It turned out that therespondents had concerns with several security aspects within CS initiatives that had anegative effect on their attitude. However, many respondents considered the initiative to bepositive if it was possible to ensure environmental benefits and most safety aspects wereprovided.

The adoption of electric vehicles in the transportation industry has increased significantly in recent years, driven by international and national environmental goals. However, this shift poses challenges for transportation companies as they adjust their fleets to accommodate electric vehicles. The range of electrified transport, which is shorter than conventional transport due to current battery technology, is influenced by various factors such as temperature, air density, topography, available charging infrastructure, loading weight, and other climate-related aspects. Electric vehicles also depend on a functional and accessible charging infrastructure, which is currently considered underdeveloped and inadequate given the growing number of electric vehicles. In addition to this, other important aspects are energy mapping, investment analysis and risk management. This study focuses on enhancing Nordic Routings route optimization system by identifying key parameters that improve route efficiency and optimization. To address the challenges of electrification and its impact on route optimization systems, this study presents a comprehensive analysis comparing conventional and electrified transport within a routing problem. The results showed that factors such as temperature, topography, loading weight, driver behavior and available charging infrastructure significantly impact range and range anxiety. These factors were analyzed through various scenarios based on scientific literature, interviews and modeling in Nordic Routings route optimization system. Furthermore, the study emphasizes the importance of meticulous pre-planning, investment analysis, route planning adjustments and accompanying risk management, summarized in a four-step model. This study also points out recommendations that are provided for managing temperature, weather condition, energy mapping, dynamic planning of charging, integrating live data on charging infrastructure and consideration of topology and loading weight. Implementation of these recommended actions within the route optimization system is essential to facilitate efficient routing for electrified transport, while also considering the current state of battery technology and charging infrastructure. / Elektrifieringen inom transportbranschen har ökat markant senaste åren till följd av internationella och nationella målsättningar för att minska den negativa miljöpåverkan. Den ökade elektrifieringen av transporter innebär dock skillnader i användning, planering och investering jämfört med konventionell transport, vilket medför en omställning för transportföretag som byter ut delar av eller hela fordonsflottan mot elektrifierade alternativ. Räckvidden för elektrifierad transport, som är kortare än konventionell transport på grund av nuvarande batteriteknik, varierar kraftigt av faktorer som temperatur- och väderförhållanden, topografi, tillgänglig laddningsinfrastruktur, lastvikt och andra fordons- eller klimatkopplade aspekter. Fortsättningsvis är elektrifierade fordon beroende av en fungerande och tillgänglig laddningsinfrastruktur, som i dagsläget anses vara underutvecklad och bristfällig utifrån den växande andelen elektrifierade fordon. Utöver detta återfinns andra faktorer som energikartläggning, investeringsanalys och riskhantering som är viktiga aspekter i planeringen av elektrifieringen. Studien som riktades mot Nordic Routings ruttoptimeringssystem utgjorde grunden för att identifiera nyckelparametrar som vidare kan implementeras och utvecklas i deras ruttoptimeringssystem. För att adressera problematiken kring elektrifieringen och hur elektrifierade transporter påverkas i ruttoptimeringssystem, presenterar denna studie en djupgående analys där konventionell och elektrifierad transport jämförs i ett ruttplaneringsproblem. Resultaten visade att faktorer som temperaturer, topologi, lastvikt, förarbeteende och tillgänglig laddningsinfrastruktur har en betydande påverkan på räckvidd och räckviddsångest. Dessa faktorer analyserades utifrån flera scenarier baserat på vetenskaplig litereratur, intervjuer och modellering i Nordic Routing ruttoptimeringssystem. Vidare belyser studien vikten av noggrann förplanering, investeringsanalys, anpassning av ruttplaneringen och den tillhörande riskhanteringen, vilket sammanfattas i en fyrstegsmodell. Slutligen presenterar studien rekommenderade åtgärder såsom hantering av temperatur- och väderförhållanden, energikartläggning och direktuppkopplade data mot laddningsinfrastrukturen, dynamisk planering av laddningsstationer samt beaktande av topologi och lastvikt. Dessa rekommenderade åtgärder behöver implementeras i ruttoptimeringssystemet för att möjliggöra effektiv ruttoptimering med elektrifierad transport, med hänsyn till dagens batteriteknik och laddningsinfrastruktur.

Cache memories have been usually implemented with Static Random-Access Memory (SRAM) technology since it is the fastest electronic memory technology. However, this technology consumes a high amount of leakage currents, which is a major design concern because leakage energy consumption increases as the transistor size shrinks. Alternative technologies are being considered to reduce this consumption. Among them, embedded Dynamic RAM (eDRAM) technology provides minimal area and leakage by design but reads are destructive and it is not as fast as SRAM. In this thesis, both SRAM and eDRAM technologies are mingled to take the advantatges that each of them o¿ers. First, they are combined at cell level to implement an n-bit macrocell consisting of one SRAM cell and n-1 eDRAM cells. The macrocell is used to build n-way set-associative hybrid ¿rst-level (L1) data caches having one SRAM way and n-1 eDRAM ways. A single SRAM way is enough to achieve good performance given the high data locality of L1 caches. Architectural mechanisms such as way-prediction, swaps, and scrub operations are considered to avoid unnecessary eDRAM reads, to maintain the Most Recently Used (MRU) data in the fast SRAM way, and to completely avoid refresh logic. Experimental results show that, compared to a conventional SRAM cache, leakage and area are largely reduced with a scarce impact on performance. The study of the bene¿ts of hybrid caches has been also carried out in second-level (L2) caches acting as Last-Level Caches (LLCs). In this case, the technologies are combined at bank level and the optimal ratio of SRAM and eDRAM banks that achieves the best trade-o¿ among performance, energy, and area is identi¿ed. Like in L1 caches, the MRU blocks are kept in the SRAM banks and they are accessed ¿rst to avoid unnecessary destructive reads. Nevertheless, refresh logic is not removed since data locality widely di¿ers in this cache level. Experimental results show that a hybrid LLC with an eighth of its banks built with SRAM technology is enough to achieve the best target trade-o¿. This dissertation also deals with performance of replacement policies in heterogeneous LLCs mainly focusing on the energy overhead incurred by refresh operations. In this thesis it is de¿ned a new concept, namely MRU-Tour (MRUT), that helps estimate reuse information of cache blocks. Based on this concept, it is proposed a family of MRUTbased replacement algorithms that randomly select the victim block among those having a single MRUT. These policies are enhanced to leverage recency of information for a few blocks and to adapt to changes in the working set of the benchmarks. Results show that the proposed MRUT policies, with simpler hardware complexity, outperform the Least Recently Used (LRU) policy and a set of the most representative state-of-the-art replacement policies for LLCs. Refresh operations represent an important fraction of the overall dynamic energy consumption of eDRAM LLCs. This fraction increases with the cache capacity, since more blocks have to be refreshed for a given period of time. Prior works have attacked the refresh energy taking into account inter-cell feature variations. Unlike these works, this thesis proposes a selective refresh policy based on the MRUT concept. The devised policy takes into account the number of MRUTs of a block to select whether the block is refreshed. In this way, many refreshes done in a typical distributed refresh policy are skipped (i.e., in those blocks having a single MRUT). This refresh mechanism is applied in the hybrid LLC memory. Results show that refresh energy consumption is largely reduced with respect to a conventional eDRAM cache, while the performance degradation is minimal with respect to a conventional SRAM cache. / Valero Bresó, A.

Mit dem Judentum stellt das 2020 erschienene Videospiel The Last of Us Part II eine Religion dar, deren Repräsentation bzw. Thematisierung auch und gerade in digitalen Spielen mit besonderen Sensibilitäten verbunden und dementsprechend selten ist. Ihren Ausdruck findet diese Darstellung in der jüdischstämmigen Deuteragonistin Dina, vor allem aber in einem vergleichsweise kurzen Spielabschnitt in einer Synagoge, der in dieser Arbeit eingehend beschrieben und aus religionswissenschaftlicher Perspektive analysiert wird. Methodisch wird dabei an die von Oliver Steffen formulierte (2017) Methode für die religionswissenschaftliche Digitalspielforschung angeknüpft, insbesondere an die vier Kriterien der Implementierung religiöser Inhalte in digitalen Spielen. So werden neben der Einbindung der jüdischen Religion in die Spielerzählung auch die Besonderheiten ihrer Einbindung in die Interaktivität bzw. Spielmechanik und damit videospielspezifische Herausforderungen und Probleme untersucht. Im Anschluss wird die weitergehende Bedeutung der jüdisch-religiösen Spielinhalte im Gesamtkontext des Spiels diskutiert, wobei die These vertreten wird, dass der Spielabschnitt in der Synagoge in zweifacher Hinsicht als Schlüsselszene fungiert und nicht nur eine im späteren Spielverlauf erkennbare Analogie auf den Nahostkonflikt vorbereitet, sondern auch auf mögliche Bezüge zur jüdischen Geschichte und Identität in der Spielreihe insgesamt verweist. Der so beschriebenen Untersuchung vorangestellt ist ein umfassender Überblick über Darstellungen des Judentums in Video- und Computerspielen generell, der die Relevanz und den weitgehenden Ausnahmecharakter der Implementierung in The Last of Us Part II erkennbar werden lässt, aber auch davon unabhängig als Anknüpfungspunkt für die weitere Forschung dienen kann.

Throughout the seventeenth century, numerous Scots became convinced that the major political and religious upheavals of their age signified the fulfillment of, or further unfolding of, the vivid prophecies described in the Book of Revelation which foretell of the final consummation of all things. To date, however, an in-depth analysis of the evolution of Scottish apocalyptic belief during the seventeenth century has never been undertaken. This thesis utilizes a wide variety of source material to demonstrate the existence of a cohesive, persistent, and largely conservative tradition of apocalyptic thought in Scotland that spanned the years 1588 to 1688. Chapter One examines several influential commentaries on the Book of Revelation published by notable Scots during the decades either side of the Union of Crowns. These works reveal many of the principal characteristics that formed the basis of the Scottish apocalyptic tradition. The most important of these traits which became a consistent feature of the tradition was the rejection of millenarianism. In recent years, historians have exaggerated the influence of millenarian ideals in Scotland during the Covenanting movement which began in 1638. Chapter Two argues that Scottish Covenanters consistently denounced millenarianism as a dangerous, subversive doctrine that could lead to the religious radicalism espoused by sixteenth-century German Anabaptists. Chapter Three looks at political and religious factors which led to the general decline of apocalyptic expectancy in Scotland during the Interregnum. It also demonstrates how, despite this decline, Scottish apocalyptic thinkers continued to uphold the primary traits of the apocalyptic tradition which surfaced over the first half of the century. Lastly, Chapter Four explains how state-enforced religious persecution of Scottish Presbyterians during the Restoration period led to the radicalisation of the tradition and inspired the violent actions of Covenanter extremists who believed they had been chosen by God to act as instruments of his divine vengeance in the latter-days.

Afin de réaliser correctement leur fonction, certains blocs analogiques ou numériques comme les miroirs de courant ou les SRAM, nécessitent des paires de transistors MOS électriquement identiques. Cependant, les dispositifs sur silicium, même appariés, subissent des variations locales aléatoires ce qui fait varier leurs performances électriques. Ce phénomène est connu sous le nom désappariement. L'objectif de cette thèse est de comprendre les causes physiques de ce désappariement, de le quantifier et de proposer des solutions pour le réduire. Dans ce contexte, quatre thèmes principaux sont développés. Le premier thème se focalise sur l'optimisation des méthodologies de mesures des phénomènes de désappariement. Une nouvelle méthode de mesure du désappariement de Vt et de β ainsi qu'un nouveau modèle de désappariement de ID sont proposés, analysés et appliqués à des données mesurées sur des technologies 28nm Bulk et FD SOI. Le second thème se concentre sur la caractérisation des différentes configurations de transistor MOS afin de proposer l'architecture optimale en fonction des applications visées. Ainsi, la possibilité de remplacer le LDEMOS par une configuration cascode est analysée en détail. Le troisième thème se focalise sur l'analyse et la modélisation des phénomènes de désappariement des transistors MOS avancés. Trois aspects sont analysés : 1) l'introduction du Ge dans le canal P des technologies 28nm BULK, 2) la suppression de la contribution de la grille sur le désappariement de Vt en utilisant la technologie 20 nm métal-Gate-Last 3) un descriptif des principaux contributeurs au désappariement de Vt, β et ID dans les technologies 28 et 14nm FD SOI. Le dernier thème traite du comportement du désappariement des transistors MOS après vieillissement. Un vieillissement NBTI a été appliqué sur des PMOS de la technologie 28nm FD SOI. Des modèles de comportement de Vt et de β en fonction du nombre de charges fixes ou d'états d'interfaces induits à l'interface Si/SiO2 ou dans l'oxyde sont proposés et analysés. / For correct operation, certain analog and digital circuits, such as current mirrors or SRAM, require pairs of MOS transistors that are electrically identical. Real devices, however, suffer from random local variations in the electrical parameters, a problem referred to as mismatch. The aim of this thesis is to understand the physical causes of mismatch, to quantify this phenomenon, and to propose solutions that enable to reduce its effects. In this context, four major areas are treated. The first one focuses on the optimization of mismatch measurement methodologies. A new technique for the measurement of Vt and β mismatch and an ID mismatch model are proposed, analyzed and applied to experimental data for 28 nm Bulk and FD SOI technologies. The second area focuses on the characterization of different configurations of MOS transistors in order to propose design architectures that are optimized for certain applications. Specifically, the possibility of replacing LDEMOS with transistors in cascode configuration is analyzed. The third area focuses on the analysis and modeling of mismatch phenomena in advanced Bulk and SOI transistors. Three aspects are analyzed: 1) the impact of the introduction of germanium in P channel of 28nm BULK transistors; 2) the elimination of the metal gate contribution to Vt mismatch by using 20nm Gate-last Bulk technology; 3) a descriptive study of the principal contributions to Vt, β and ID mismatch in 28 and 14 nm FD SOI technologies. The last area treats the mismatch trends with transistor aging. NBTI stress tests were applied to PMOS 28nm FD SOI transistors. Models of the Vt and β mismatch trends as a function of the induced interface traps and fixed charges at the Si/SiO2 interface and in the oxide were developed and discussed.
