Esta ultima caracter stica e a de maior motiva c~ao para esta tese, uma vez que pouco ainda se tem reportado a respeito da supercondutividade em multicamadas constitu das por supercondutor(S)/supercondutor(S0). Neste trabalho, estudamos tr^es novos sistemas nanoestruturados formados por supercondutores elementares, de baixa temperatura cr tica, tais como ni obio (Nb), chumbo (Pb) e estanho (Sn), a saber, a tricamada Nb(5)/Pb(500)/Nb(50) e as multicamadas Nb(100)/[Sn(50)/Nb(50)]7 e Cr(10)/Nb(100)/[Sn(50)/Nb(50)]7, onde o termo entre par^enteses indica a espessura da referida camada em nan^ometros e os colchetes indicam que a estrutura Nb/Sn e repetida 7 vezes. Para compara c~ao, tamb em s~ao analisados lmes de refer^encia de Nb, Pb e Sn. Os lmes e as multicamadas foram crescidos a temperatura ambiente por deposi c~ao via sputtering, utilizando fontes DC e RF. As amostras foram caracterizadas por difra c~ao de raios X de baixo ^angulo, microscopia eletr^onica de varredura e por microscopia de for ca at^omica. As propriedades supercondutoras foram estudadas atrav es de medidas magn eticas e de transporte el etrico. Magnetiza c~ao e resistividade foram medidas como fun c~oes da temperatura e do campo magn etico aplicado perpendicular e paralelamente as camadas. Os tr^es sistemas apresentaram transi c~oes supercondutoras abruptas, tanto na magnetiza c~ao quanto na resistividade em fun c~ao da temperatura, com os valores de TC obtidos de 7,2 K para o Nb/Pb/Nb, 5,2 K para o Nb/[Sn/Nb]7 e 3,7 K para o Cr/Nb/[Sn/Nb]7. As propriedades supercondutoras dos lmes de Pb, Nb e Sn, tais como TC, 0Hc2 e comprimentos caracter sticos apresentaram coer^encia com os valores reportados na literatura, con rmando a boa qualidade das camadas. Flux jumps s~ao observados nos loops de histerese em todos os sistemas, os quais s~ao atribu dos a instabilidades termomagn eticas. A amostra Nb/Pb/Nb apresentou uma curvatura positiva na depend^encia de 0Hc2(T), indicando que a supercondutividade ocorre preferencialmente na camada de Pb para T > T e preferencialmente na camada de Nb para T < T , de acordo com a teoria de Takahashi-Tachiki. Os comprimentos caracter sticos s~ao calculados, classi cando as multicamadas como supercondutores do tipo II. Veri camos grande in u^encia do material magn etico Cr na supercondutividade da multicamada, causando a diminui c~ao da temperatura cr tica do sistema e modi cando o comportamento dos campos cr ticos inferior e superior. A depend^encia de 0Hc1(T), em todos os sistemas, revelou um comportamento n~ao convencional, que e atribu do a uma manifesta c~ao de sistemas multicomponentes com componentes espacialmente separadas. / The study of superconducting multilayers systems has achieved much interest in the research of new materials. Besides their wide technological applicability, these structures o er fascinating possibilities to observe new phenomena in superconductivity. The latter characteristic is the fundamental motivation for this thesis, since a little has been reported about multilayers constituted of superconductor(S)/superconductor(S0). In this work, we have studied three new nanostructured systems formed by low critical temperature conventional superconductors, such as niobium (Nb), lead (Pb) and tin (Sn): the trilayer Nb(5)/Pb(500)/Nb(50) and the multilayers Nb(100)/[Sn(50)/Nb(50)]7 and Cr(10)/Nb(100)/[Sn(50)/Nb(50)]7. The term in parenthesis indicates the thickness of the layer in nanometers and the brackets that Nb/Sn structure is repeated 7 times. For comparison, the reference lms of Nb, Pb and Sn were also analyzed. The thin lms and multilayers were growth at room temperature via sputtering deposition, by using DC and RF sources. The samples were characterized for small angle X ray di raction, scanning electron microscopy (SEM), and atomic force microscopy (AFM). The superconducting properties were investigated through magnetic and electric transport measurements. The magnetization and resistivity were obtained as functions of temperature and magnetic eld applied both perpendicularly and parallel to the layers. All the multilayers systems have showed sharp superconducting transitions in the dependence of magnetization and resistivity with the temperature. The multilayers critical temperatures were found to be 7.2 K for Nb/Pb/Nb, 5.2 K for Nb/[Sn/Nb]7 and 3.7 K for Cr/Nb/[Sn/Nb]7. The superconducting properties of reference lms Pb, Nb and Sn, such as critical temperature, upper critical eld and characteristic lengths were consistent with the literature values, con rming the good quality of the samples. In the three systems ux jumps were observed, which are attributed to thermomagnetic instabilities. The Ginzburg-Landau parameter is estimated, classifying the multilayers as type II superconductors. In the case of Nb/Pb/Nb sample, it presented an upward curvature in the 0Hc2(T) diagrams, which is a signature of superconductivity nucleation in the each layer, in accordance with Takahashi-Tachiki theory for multilayered systems. We found out a noticeable in uence of the magnetic material Cr on the multilayer superconducting properties, reducing the critical temperature of the system and modifying the lower and upper critical elds behavior. The dependence of 0Hc1(T), of all the multilayers, revealed a non-conventional behavior feature, which is consistent with a multicomponent behavior with spatially separated components.

Este trabalho tem por objetivo analisar os determinantes locais da inovação no Brasil e avaliar sua dinâmica espacial. Especificamente, avalia-se como a P&D das empresas locais, a pesquisa universitária da região, o nível de adensamento urbano e a relativa especialização ou diversificação do sistema produtivo local afetam a inovação regional. Para isso, foi realizada uma Análise Exploratória de Dados Espaciais e a estimação de um modelo econométrico utilizando como medida do resultado de inovação o número de patentes por habitante das microrregiões. É possível notar que a inovação está desigualmente distribuída pelo espaço geográfico e se concentra especialmente nas Regiões Sul e Sudeste, onde se encontram os principais clusters inovativos. O modelo empírico adotado se baseia na Função de Produção de Conhecimento aplicada às regiões e é estimado por meio de um Tobit Espacial Autorregressivo (SAR-Tobit). O uso de um modelo SAR-Tobit permite lidar de modo mais adequado com um grande número de regiões sem patentes, além disso, foram feitos diversos testes adicionais que buscam assegurar a qualidade dos resultados inferenciais. A estimação do modelo desse trabalho indica que maiores níveis regionais de P&D industrial e da pesquisa universitária implicam em maior inovação, medida pelas patentes. Ao mesmo tempo, as regiões adensadas e diversificadas tendem a apresentar um melhor desempenho inovativo, o que aponta para existência de vantagens de caráter jacobiano no país. Por fim, a inovação local é afetada positivamente pela proximidade de microrregiões mais inovadoras, o que corrobora a existência de transbordamentos de conhecimento inter-regionais da inovação. / The aim of this thesis is to analyze determinants of local innovation in Brazil and assess their spatial dynamic. Specifically, it evaluates how the R&D of local firms, regional university research, urban density and specialization or diversification of local industrial system affects regional innovation. This purpose is achieved by means of an Exploratory Spatial Data Analysis and the estimation of an econometric model using the number of patents per capita as a measure of local innovative outputs. The results shows that innovation is not homogeneously distributed in the Brazilian geographic area and is especially concentrated in South and Southeast Regions, where the main innovation clusters are located. The empirical model adopted is based on the Knowledge Production Function applied to regions and is estimated using a Tobit Spatial Autoregressive (SAR-Tobit). The use of a SAR-Tobit model allows to deal more appropriately with a large number of regions without patents. Moreover, several additional tests were performed to ensure the quality of inferential results. The estimation of the model of this work indicates that higher levels of regional industrial R&D and university research imply greater innovation, measured by patents. At the same time, denser and diverse regions tend to present a better innovative performance, pointing to the existence of Jacobian advantages. Finally, local innovation is positively affected by the proximity of the most innovative micro-regions, which confirms the existence of interregional knowledge spillovers for innovation.

In a world where insecurities, violence and disasters seem to be increasing on a daily basis, compassion, a moral sentiment of co-suffering and motivation to alleviate it, plays an important role, especially in humanitarian action. However, compassion is not a constant feeling, and our emotions and compassion towards tragedies do not always resonate with egalitarian principles. This thesis seeks to explore the potential relationship between field experience, in humanitarian action, and compassion satisfaction and compassion fatigue. Departing from two contrasting hypotheses, grounded in theories of compassion, it investigates the factors, relating to field experience, that affect this moral sentiment, in a single case study of the Network on Humanitarian Action (NOHA). Through a quantitative survey design, combined with semi-structured interviews, the study finds that there exists no isolated correlation between field experience and compassion fatigue or satisfaction. However, the study concludes that compassion is affected by several intervening variables, relating to field experience, which can result in either compassion fatigue or satisfaction, resonating with both hypotheses.

Magister Scientiae (Biodiversity and Conservation Biology) / This thesis looks at aspects relating to vegetated open space in the quaternary catchment of the Lourens River, Cape Town, South Africa in 2005 and at GoogleEarth as a source of imagery for research. The research questions were: “Is GoogleEarth a suitable source of imagery for spatial analysis of landscapes?”; “What was the potential access (proximity) to vegetated open space of at least 900 m2 in the Lourens River quaternary catchment in 2005?”; “How many vegetated open spaces with an area of at least 900 m2 were present in the Lourens River quaternary catchment in 2005?” and “What spaces within the urban edge in the Lourens River quaternary catchment can be said to have some protection from development?” Open space has multiple benefits for humans in terms of health and social interaction.In urban areas, it is also important for biodiversity conservation. In Cape Town, this is critical since the city has critically endangered national vegetation types that only occur within its boundaries and 319 IUCN Red List species within its boundaries.Proximity does not reflect use of open space which is affected by the size of the open space, quality of the open space, neighbourhood attributes and individual and collective perceptions of the open space. Quality of vegetated open space is dependent on its facilities and maintenance which are largely determined by its management. In Cape Town, open space management is mainly mowing/brush cutting all spaces which has a negative impact on biodiversity retention. Mowing is continued because of popular demand so action needs to be taken to change popular perceptions.Google Earth is readily available and widely used. It is used for research in diverse disciplines. Local Internet connection problems complicated this study. Alignment and projection problems were encountered in this study. Thus Google Earth geospatial issues make it a poor choice of imagery source for large scale spatial analysis of landscapes.Open space was digitized in Google Earth and transferred to a propriety GIS for editing. Vegetated spaces with a minimum of 900 m2 and a width of at least 15 m were selected from the approximately 1025 digitised spaces. Google Earth imagery was used because it is readily available. Euclidean distances of 300 m, 500 m, 800 m and 900 m (taken from literature) were used to buffer the digitized vegetated open spaces and other data on schools, train stations, bus routes and taxi routes in and within 900 m of the catchment. Buffer analysis was carried out. Data from the City of Cape Town and a schools layer were used to determine the number of cemeteries,community parks, nature reserves and school grounds – space regarded as having some protection from development - within the urban edge of the city and what area they covered.Within or partially within the Lourens River quaternary catchment, 593 vegetated open spaces of at least 900 m2 were identified. The analysis showed that only two houses were beyond 300 m from a vegetated open space. There was vegetated open space within 300 m of all the schools, stations, bus and taxi routes within the catchment and in close proximity to the catchment. Within the urban edge, only 124 spaces were found to be protected, of which only one was a nature reserve.Most of the open spaces are not formally designated as open space and are vulnerable to development. Much development has taken place since 2005 in the Lourens River quaternary catchment so action is needed to ensure proximity to vegetated open space remains a positive feature of the area.Expanding the present research to cover a larger area would provide additional baseline data. Further research could consider the loss of open space over time and the impact of management on the quality of designated open space.

Bluetooth Low Energy is becoming increasingly popular in mobile applications due to the possibility of using it for proximity data. Proximity can be estimated by measuring the strength of the Bluetooth signal, and actions can then be performed based on a user's proximity to a certain location or object. One of the most interesting applications of proximity information is automating common tasks; this paper evaluates Bluetooth Low Energy in the context of using smartphones to automatically unlock a door when a user approaches the door. Measurements were performed to determine signal strength reliability, energy consumption and connection latency. The results show that Bluetooth Low Energy is a suitable technology for proximity-based door locks despite the large variance in signal strength.

Dans un contexte concurrentiel et réglementaire croissant des banques, face à une crise financière qui interroge les usages de l’argent, peut-on faire de la banque autrement ? Nous tentons de répondre à cette question en centrant notre analyse sur le cas de La Nef, petite coopérative de finance solidaire fondée sur un projet alternatif. La Nef, d’abord institution financière et disposant aujourd’hui d’un agrément bancaire, en 20 ans a grandi et s’est professionnalisée. Sa trajectoire est marquée par des formes d’isomorphismes que nous identifions et qui provoquent une hybridation de son modèle coopératif. Nous construisons et analysons l’installation des banquiers itinérants comme innovation organisationnelle dans le but de la réaffirmation du projet coopératif. En apportant de l’hétéromorphisme et de l’hetéropraxisme dans l’organisation, ces banquiers itinérants ancrent l’organisation dans son territoire et les enjeux de son développement. Cette expérimentation constitue-t-elle un processus de reconquête coopérative, et qu’en est-il de sa diffusion ? Nous avons participé et suivi les processus à l’œuvre dans le cadre d’une recherche intervention sur 5 ans. Notre cadre d’analyse s’inscrit dans une perspective néo institutionnaliste et articule isomorphisme, proximité et traduction. Nos résultats montrent que l’implantation des banquiers itinérants redynamise le tissu coopératif et le sociétariat et amène une croissance de l’activité. Elle entraine un rééquilibrage des phénomènes d’hybridation favorable au projet social et à l’activité économique. Le déploiement des Banquiers Itinérants est à l’œuvre et méritera d’être analysé dans les formes de son développement. / In a context of increasing competition and international regulation in the banking system, and facing a financial crisis which questions the uses of money, is another way of banking possible? We try to answer this question through the analysis of the case study of the Nef, a little solidarity-based finance cooperative based on an alternative project. The Nef, at first a financial institution which later in 2014 got a banking agreement, grew up over 20 years and professionalised. We identify the various types of isomorphism which marked its trajectory and cause a hybridisation of its cooperative model. We build up and analyse the set up of itinerant bankers as an organisational innovation, in order to reaffirm the cooperative project. As they bring heteromorphism and heteropraxy into the organisation, these itinerant bankers anchor the organisation in its territory and the stakes of its development. Is this experiment a process of cooperative recovery, and will it spread ? We took part and followed the undergoing processes within a 5 year intervention research. Our analysis focuses on isomorphism, proximity and translation in a neo-institutional perspective. Our results show that itinerant bankers set up revitalise the cooperative system and shareholder relations as well as a business growth. Thus the experience show a rebalancing in hybridisation phenomena favourable to the social project and stimulating economic activity. The deployment of itinerant bankers is recent, and will deserve to be studied in its forms of development.

Abstract Users of mobile devices induce detrimental electrical effects on the antenna when devices are operated in close proximity to either the head, hand or fingers. A totally covered antenna can suffer over 10 dB gain loss and force an increase in the output power of the device, which additionally causes shorter battery life and higher emissions in terms of the specific absorption rate (SAR) and hearing aid compatibility (HAC). The user effect can be minimized with compensation methods such as active antenna tuning or a spatial antenna selection. In this thesis, capacitive proximity sensors are investigated in order to provide new characteristics for user effect compensation. The thesis has three parts. In the first, hand positions along the device chassis are measured with the antenna integrated capacitive sensor. The results are in proportion to the induced hand loss in the antenna. Secondly, discrete electrode sensors are studied as hand and single finger proximity recognition and are found to have a good performance in applications. Thirdly, weaknesses of integrated and discrete sensors are evaluated. The discrete sensor had an induced low antenna loss of 0.05–0.20 dB in the 1–2 GHz bands. In contrast, the integrated sensor caused radio interference in proper GSM channels, decreasing the sensitivity of the radio receiver. The capacitive sensor is able to sense the user proximity effect regardless of antenna matching, which may be changed in a complex manner when more than one electrical resonance is used in the same frequency band or when the matching is modified mainly by the resistive component. In multiple-antenna applications, capacitive sensors are able to maintain up-dated information of user loads of all antennas. Combining the results, the discrete electrode sensors fulfilled the technical and operational objectives of this thesis. They are able to detect a single finger or other user objects, they have low losses and they can be located in such a way that will not consume extra room in mobile devices. / Tiivistelmä Kannettavien päätelaitteiden käyttäjät aiheuttavat sähköisiä häviöita laitteen antennissa kun laitetta käytetään käden, pään tai sormien läheisyydessä. Kokonaan peitetyn antennin häviö voi olla yli 10 dB, mikä johtaa laitteessa lisääntyneeseen tehontarpeeseen, lyhyempään pariston kestoon ja korkeampiin haitta-arvoihin SAR ja HAC mittauksissa. Käyttäjän vaikutusta voidaan minimoida kompensaatiotekniikoilla kuten antennin säädöllä ja -valinnalla. Tässä työssä kapasitiivisia antureita tutkittiin uusien käyttäjävaikutuksen kompensaatiotekniikoiden löytämiseksi. Työ jakaantuu kolmeen osaan. Ensimmäiseksi käden sijainti laitteen rungon suhteen on mitattu kapasitiivisella anturilla. Nämä tulokset ovat verrannollisia käden aiheuttamaan kuormaan antennissa. Toiseksi erillisiä antureita tutkittiin käden ja sormien havaitsemiseksi hyvällä menestyksellä eri sovelluksissa. Kolmanneksi arvioitiin antennin integroidun ja erillisen anturin heikkouksia. Erillisen anturin aiheuttama häviö antenniin oli 0.05–0.20 dB 1–2 GHz taajuuskaistalla. Vastaavasti integroitu anturi aiheutti radiohäiriöitä tietyillä radiokanavilla, mikä heikentää vastaanottimen herkkyyttä. Kapasitiivinen anturi havaitsee käyttäjän läheisyyden riippumatta antennin sovituksesta. Sovitus voi muuttua monimutkaisesti kun useampaa sähköistä resonanssia käytetään samalla taajuuskaistalla tai sovitukseen vaikuttaa sähköisesti resistiivinen kuorma. Moniantennirakenteissa kapasitiiviset anturit voivat tuottaa jatkuvaa informaatiota käyttäjän aiheuttamasta kuormasta eri antenneissa. Erilliset kapasitiiviset anturit täyttivät ne tekniset ja toiminnalliset vaatimukset, jotka työlle aluksi asetettiin. Niillä voidaan havaita yksittäinen sormi tai muu kohde, ne ovat pienihäviöisiä, ja ne voidaan sijoittaa tilaa säästävällä tavalla nykyisiin päätelaitteisiin.

Doctor of Philosophy / Curriculum and Instruction Programs / Michael F. Perl / BeEtta L. Stoney / America is in the midst of an obesity epidemic (Wechsler, McKenna, Lee, & Dietz, 2004). According to Wechsler et al., physical inactivity is a major contributor to this issue. Burnette (1999), reports certain behaviors and instructional strategies help teachers to build stronger teaching/learning relationships with students, and that some specific behaviors may be the most influential. Teacher feedback and teacher proximity are two specific behaviors that are important in a physical education setting. Hastie (1998) and Lund (1990), report that when physical education teachers provide feedback and maintain proximity to students, learning may be enhanced. This study examined the frequency of teacher feedback and teacher proximity in relation to student body mass index (BMI) and student gender. Fifteen Kansas middle school physical education teachers were observed delivering skill based lessons to two classes of students. Event recording, a form of systematic observation, was used in data collection. A multivariate analysis of variance was conducted with independent samples T-tests conducted for specific demographic data. Results indicated no significant differences in the frequency of teacher feedback and teacher proximity in relation to student body mass index (BMI) or student gender. Results of the analysis of various pieces of demographic information showed teachers who use some of the Physical Focus Curriculum activities had a higher rate per minute of teacher feedback than teachers who use none of the curriculum. Analysis also showed that teachers using more individualized skill based activities provided significantly higher rates of feedback and proximity than those conducting large group activities. Further analysis of demographic data revealed those teachers currently coaching a sport provided less feedback and proximity to students in class than those not currently coaching. Membership in the state professional organization did not have any effect upon rates of teacher feedback or proximity. The effects of teacher gender on rates of feedback and proximity showed female teachers are more proximal to all students than male teachers. Recommendations to be considered when conducting further research include increasing the sample size, development of more specific instrumentation to measure rates of feedback and proximity in an activity setting, implementing more control of the type of activity and instruction provided, and including more diversity in the study.

Small businesses located in the most sparsely populated and peripheral parts of Europe are frequently believed to be marginalised with respect to the processes of economic globalisation. This thesis proposes to explore an alternative perspective for understanding how small businesses that are located at the geographical margins engage with the globalised economy. Distance is no longer a purely physical phenomenon. Meanwhile, networks are considered to be the primary means for small firms to mobilise external resources and stay competitive. Acknowledging these conceptual shifts, this thesis explores how peripheral small businesses develop network configurations with multiple actors across multiple geographical scales to engage in the global economy. This thesis consists of four papers and a cover essay. The four papers share the theme of the network interaction of small and medium-sized enterprises (SMEs) in peripheral regions and discuss this theme from various perspectives with different research questions. The papers use combinations of quantitative and qualitative analytical methods to empirically investigate the configuration of small firm networks in the case study of Upper Norrland in Sweden. The cover essay introduces the overarching conceptual framework that is grounded in ideas from the seminal work of Granovetter on the social embeddedness of economic interactions and the ‘strength of weak ties’, and this essay contributes to the debate in geography on multi-scalar proximity dynamics. The empirical findings of the papers describe the collaborative and transactional forms of firm relations in peripheral regions and discuss the role of key actors—such as international customers or regional intermediary organisations—in bridging the local and extra-local dimensions of small firm networks. The conceptual contribution of this thesis corroborates the understanding that small firm development requires a balance between regional and international networks. This thesis also contributes to the debate on development policies for peripheral regions by offering insights into the manner in which institutional support for the design and implementation of open, flexible network arrangements may provide a leverage effect for small firm development. / <p>At the time of the doctoral defense, the following papers were unpublished and had a status as follows: Paper 3: Submitted.

The current research sought to clarify the diverging relationships between counterfactual thinking and hindsight bias observed in the literature thus far. In a non-legal context, Roese and Olson (1996) found a positive relationship between counterfactuals and hindsight bias, such that counterfactual mutations that undid the outcome also increased participants’ ratings of the outcome’s a priori likelihood. Further, they determined that this relationship is mediated by causal attributions about the counterfactually mutated antecedent event. Conversely, in the context of a civil lawsuit, Robbennolt and Sobus (1997) found that the relationship between counterfactual thinking and hindsight bias is negative. The current research sought to resolve the conflicting findings in the literature within a legal context. In Experiment One, the manipulation of the normality of the defendant’s target behavior, designed to manipulate participants’ counterfactual thoughts about said behavior, did moderate the hindsight effect of outcome knowledge on mock jurors’ judgments of the foreseeability of that outcome as well as their negligence verdicts. Although I predicted that counterfactual thinking would increase, or exacerbate, the hindsight bias, as found by Roese and Olson (1996), my results provided some support for Robbenolt and Sobus’s (1997) finding that counterfactual thinking decreases the hindsight bias. Behavior normality did not moderate the hindsight effect of outcome knowledge in Experiment Two, nor did causal proximity in Experiment Three. Additionally, my hypothesis that self-referencing may be an effective hindsight debiasing technique received little support across the three experiments. Although both the self-referencing instructions and self-report measure consistently decreased mock jurors’ likelihood of finding the defendant negligent, and self-referencing instructions decreased their foreseeability ratings in studies two and three, the self-referencing manipulation did not interact with outcome knowledge to moderate a hindsight bias effect on either foreseeability or negligence judgments. The consistent pattern of results across the three experiments, however, suggests that self-referencing may be an effective technique in reducing the likelihood of negligence verdicts.
