Doctor of Philosophy (PhD), ScienceA concise stereo-selective synthesis of a protected form of APTO 1, an unusual amino acid component of microsclerodermin C 2, was undertaken. Sequential Sharpless Asymmetric Aminohydroxylation (AA) and Asymmetric Dihydroxylation (AD) reactions were used to introduce the chiral amino and hydroxyl groups. Specific directing groups were chosen to ensure high regio- and enantio-selectivity in these reactions. The target compound was reached in a linear reaction sequence of fourteen steps. The strategy was designed to generate common intermediates which could be used to access analogous amino acid fragments in other microsclerodermins. A protected form of AETD 3, from microsclerodermin E, was synthesised via a late-stage common intermediate. Initial studies into the modification of the sequence to allow access to AMPTD 4 and 10-methyl AMPTD 5 were made.

Doença respiratória exacerbada por aspirina, conhecida como AERD (Aspirin exacerbated respiratory disease) é caracterizada por rinossinusite crônica eosinofílica, polipose nasossinusal, asma e hipersensibilidade a aspirina e outros anti-inflamatórios não-esteroidais. Expressão aumentada do biomarcador periostina foi descrita em pacientes com AERD, em tecido nasossinusal, incluindo membrana basal, matriz extracelular e pólipo nasal. Avaliamos níveis de periostina sérica em pacientes com AERD e comparamos com níveis em pacientes com rinite alérgica perene (RAP) e indivíduos saudáveis. Foram selecionados 29 pacientes (20F/9M) com diagnóstico de AERD, dentre aqueles atendidos nos Ambulatórios de Alergia e de Otorrinolaringologia do Hospital das Clínicas da Faculdade de Medicina de Ribeirão Preto, Universidade de São Paulo (HCFMRP-USP). Estes pacientes realizaram exames confirmatórios, incluindo teste de provocação oral com aspirina, e foram submetidos a biópsia de pólipos nasais por nasofibroscopia. Como controles, foram selecionados 12 pacientes com RAP (9F/3M) e 23 indivíduos saudáveis (14F/9M). Eosinófilos foram quantificados em sangue periférico e em tecido de pólipo ou mucosa nasal. IgE total foi determinada por ImmunoCAP, e periostina sérica foi medida por ELISA. Número de eosinófilos teciduais por campo de grande aumento (CGA), número de eosinófilos por milímetro cúbico em sangue periférico, níveis de IgE total e de periostina sérica em pacientes com AERD foram comparados aos de pacientes com RAP e indivíduos saudáveis. Pacientes com AERD tinham idade maior (mediana 54 anos, faixa 22-60) que pacientes com RAP (mediana 30 anos, faixa 19-57, p=0,0001) e indivíduos saudáveis (mediana 29 anos, faixa 19-53, p=0,0001), sem diferença entre os sexos. Números de eosinófilos em sangue periférico e em tecido foram mais elevados em pacientes com AERD que em pacientes com RAP e indivíduos saudáveis. A mediana do número de eosinófilos em sangue periférico foi 640eos/µL (faixa 100-5.100); 200eos/µL (faixa 100-500); e 100 eos/µL (faixa 100-400) em pacientes com AERD, RAP e indivíduos saudáveis, respectivamente (AERD versus RAP, p=0,0003; AERD versus indivíduos saudáveis, p=0,01). A média do número de eosinófilos teciduais foi de 113,3células/CGA; 2,5células/CGA; e 0,7células/CGA, respectivamente (AERD versus RAP, p=0,017; AERD versus indivíduos saudáveis p=0,003). A média geométrica da IgE total foi de 290,18kU/L (faixa 59,5-8.140); 69,96kU/mL (faixa 5,5-898); e 43,14kU/mL (faixa 4- 1.328) em pacientes com AERD, RAP e indivíduos saudáveis, respectivamente, sem diferença entre os grupos. Periostina sérica foi mais elevada em pacientes com AERD quando comparados a indivíduos saudáveis. A mediana de periostina sérica foi de 602ng/ml (faixa 290,7-1.055); 535,6ng/mL (faixa 209-733,2); e 496,7mg/mL (faixa 327,4-713,4), em pacientes com AERD, RAP e indivíduos saudáveis, respectivamente (AERD versus indivíduos saudáveis, p=0,01). Em subgrupo de pacientes brasileiros com AERD, observamos elevado número de eosinófilos em sangue periférico e em tecido, quando comparados a pacientes com RAP e indivíduos saudáveis. Níveis mais elevados de periostina sérica foram observados em pacientes com AERD, quando comparados a indivíduos saudáveis, indicando forte resposta do tipo 2 em pacientes com AERD em nosso meioAspirin exacerbated respiratory disease (also known as AERD), is characterized by eosinophilic chronic hypertrophic rhinosinusitis, nasosinusal polyps, asthma and hypersensitivity to Aspirin or other non-steroidal anti-inflammatory drugs. A higher expression of the biomarker periostin has been described in patients with AERD, in nasosinusal tissue, including basal membrane, extracellular matrix and nasal polyps. We evaluated the levels of serum periostin in patients with AERD, and compare those levels with patients with perennial allergic rhinitis (PAR), and with healthy subjects. Twenty-nine patients (20F/9M) with AERD were selected from the Allergy and Otolaryngology Clinics, from the Clinical Hospital of the Ribeirão Preto Medicine School, University of São Paulo (HCFMRP-USP). Those patients underwent confirmatory exams, such as Oral Provocation test with aspirin, and were submitted to polyp biopsy through nasofibroscopy. As a control group, 12 patients (9F/3M) with PAR and 23 healthy subjects (14F/9M) were selected. Eosinophils were quantified in peripheral blood and in polyp tissue or nasal mucosa. Total IgE was determined by ImmunoCAP, and serum periostin was measured by ELISA. The number of tissue eosinophils by high magnification field (HMF), number of eosinophils by cubic milliliter in peripheral blood, total IgE levels and serum periostin levels in patients with AERD were compared with those from patients with PAR and healthy subjects. Patients with AERD were older (median 54 years, and range 22-60) than patients with PAR (median 30 years, range 19-57, p=0,0001) and healthy subjects (median 29 years, range 19-53, p=0,0001), with no difference between genders. The numbers of eosinophils in peripheral blood and in tissue were higher in patients with AERD than patients with PAR or healthy subjects. The median of eosinophil number in peripheral blood was 640eos/µL (range 100-5.100); 200eos/µL (range 100-500); e 100eos/µL (range 100-400) in patients with AERD, PAR and healthy subjects respectively (AERD vs PAR, p=0,0003; AERD vs healthy subjects, p=0,01). The average number of tissue eosinophils was 113,3cels/HMF; 2,5cels/HMF; e 0,7cels/HMF, respectively (AERD vs PAR, p=0,017; AERD vs healthy subjects, p=0,003). The geometric mean for total IgE was 290,18kU/mL (range 59,5-8.140); 69,96kU/mL (range 5,5-898); and 43,14kU/mL (range 4-1.328) in patients with AERD, PAR and healthy subjects respectively, with no difference between the groups. Serum periostin was higher in patients with AERD when compared with healthy subjects. The median for serum periostin was 602ng/ml (range 290,7-1.055); 535,6ng/mL (range 209-733,2); e 496,7ng/mL (range 327,4-713,4), in patients with AERD, PAR and healthy subjects respectively (AERD vs healthy subjects, p=0,01). In a Brazilian subgroup of patients with AERD, we observed an elevated number of eosinophils in peripheral blood and tissue, when compared with patients with PAR and healthy subjects. Higher levels of serum periostin were observed in patients with AERD, when compared with healthy subjects, indicating a strong type 2 response in patients with AERD in our environment.

Full textAbstract:
Varje år drabbas ca 10 000 människor av hjärtstopp utanför sjukhus och av dem är det endast 500 som överlever. Sannolikheten för överlevnad ökar upp mot 75% vid användning av hjärtstartare. Kandidatexamensarbetet gjordes i uppdrag av Servicia Medical, där målet var att analysera den nordiska marknaden för AED, utifrån att undersöka största återförsäljarna, attraktiva platser för placering av AED, prisutveckling och tillväxt. Marknadsundersökningen omfattar enbart Sverige, Finland och Danmark. För att ta reda på vilka återförsäljare som är störst utfördes en webbaserad informationssökning, samt telefonsamtal och mejlväxling med generalagenter. Data för attraktiva platser och tillväxt erhölls från olika verksamheter. Intervjuer, mejl och telefonsamtal utnyttjades för att få fram prisutvecklingen. Återförsäljarna delades in i två kategorier, där den ena avsåg företag som har fokus på första hjälpen och den andra företag med ospecifik fokusering. Information som krävdes för att undersöka vilka platser som är mest attraktiva, samt tillväxten i Finland och Danmark saknades. Gator och torg, tåg, buss, båt och spårtrafik är de mest attraktiva platserna för placering av AED i Sverige. Under de senaste fem åren har priset sjunkit i Sverige och Danmark. Tillväxten i dessa länder är olika där Sverige har en växande trend, medan Danmark har en ojämn och otydlig. Ingen slutsats kan dras för tillväxten i Finland.Each year about 10 000 people get a cardiac arrest outside hospital and only 500 of them survives. Defibrillators are an efficient treatment for cardiac arrest, where the probability of survival increases up to 75%. This Bachelor project is done on behalf of Servicia Medical, where the goal is to analyze the Nordic market of AED by investigating the greatest retailers, the most attractive locations to place AED, price development and growth. The market research covers only Sweden, Finland and Denmark. To discover the greatest retailers, web-based research was performed as well as phone-calls and e-mail exchanges with general agents. Data for analyzing attractive locations and growth were obtained from various businesses. Interviews, e-mails and phone calls were used to derive price development. The found retailers were divided into two categories. The first category was companies that focus on first aid and the second one had a non-specific focus. Some Finnish and Danish businesses had a lack of required information to examine the most attractive locations and growth. Streets and squares, trains, busses, boats and rail traffic are the most attractive locations in Sweden to place AED. During the past five years prices have decreased in Sweden and Denmark. The growth in these countries is different. Whilst Sweden has a growing trend, Denmark has an uneven and unclear trend. No conclusion can be drawn for the growth in Finland.

Full textAbstract:
The number of out of hospital cardiac arrest (OHCAs) that occur in Sweden every year is really high and there are very few survivors. When a cardiac arrest happens the heart loses its original rhythm and to find it again the heart needs to be shocked within minutes. There is on going research to see what can be done to improve the survival rate. Publicly accessible defibrillators are one thing that is being implemented. Another solution being considered right now is the possibility of delivering a defibrillator by a drone, especially to places that are difficult to be reached by the ambulance. A test flight with this kind of drone will take place in Stockholm, Sweden in June 2015 and the purpose of this thesis was to analyze where the most suitable place would be to start the drone from for a test flight. The area studied was Stockholm County and the data used contained Out of Hospital Cardiac arrest occurrences between the years of 2006 and 2013 including the time it took for the ambulance to arrive at the scene. The analysis was done with Multi Criteria Evaluation. Multi Criteria Evaluation is a power spatial analysis tool that considers multiple criteria in decision-making environments. With Multi Criteria Evaluation suitable places can be found by adding different data and weighing them according to their importance. In this study a raster with interpolated values was produced from ambulance arrival times and this was weighed against a raster created from the density of previous OHCA cases. Results showed that the best place for a drone like this would be the city center since that is where most OHCAs occur but also the northern parts of the archipelago because of the time it takes for the ambulance to get there.

Full textAbstract:
The important concept of equilibrium has always been controversial in ecology, but a new, more general concept, an asymptotic environmentally determined trajectory (AEDT), overcomes many concerns with equilibrium by realistically incorporating long-term climate change while retaining much of the predictive power of a stable equilibrium. A population or ecological community is predicted to approach its AEDT, which is a function of time reflecting environmental history and biology. The AEDT invokes familiar questions and predictions but in a more realistic context in which consideration of past environments and a future changing profoundly due to human influence becomes possible. Strong applications are also predicted in population genetics, evolution, earth sciences, and economics.

Full textAbstract:
Sammanfattning Efter utförd praktik på fartyg ansåg vi att det övades för lite på HLR, hjärt- och lungräddning, och D-HLR, hjärt- och lungräddning med hjärtstartare, samt att det inte fanns hjärtstartare ombord på alla fartyg. Syftet med detta examensarbete är att undersöka de riktlinjer som finns för utrustningskrav på hjärtstartare ombord på svenska, norska och danska fartyg med fokus på Sverige och svenska rederier. Metoden genomfördes genom en kvantitativ metod där ett frågeformulär skickades ut via e-mail till samtliga rederier registrerade som medlemmar i Sveriges Redareförening. Ett annat frågeformulär skickades till de skandinaviska sjöfartsverken, innehållande kvalitativa frågeställningar. I studien utfördes även kvalitativa intervjuer. Av resultatet framgår att 17 av de 22 rederier som vi fick svar av hade hjärtstartare ombord i sina fartyg, och ungefär hälften hade haft en incident ombord. Det framgår även i vår studie att det inte finns några krav gällande hjärtstartare och utbildning nationellt, såväl som internationellt.Abstract Whilst the on- board training was carried out, we considered the amount of training onboard on the behalf of CPR and AED to be unsatisfying. The purpose of this study is to examine the guidelines for the equipment that should be held onboard, with regard to AED, onboard Swedish, Norwegian and Danish ships with focus on Sweden and Swedish companies. The method used for this essay was carried out by sending out a question form by e-mail to all companies registered as members of “Sveriges Redareförening”. We sent different questions to the Scandinavian maritime administrations, and also performed interviews. As shown in the result, 17 of the 22 companies that filled in the form answered that they have at least one AED onboard each of their ships and about half of the companies have had an incident onboard. It is apparent in our studies that no national or international requirements exist which are mandatory.

Fruit flies are serious pests of fruit around the world, as their maggots destroy fruit by feeding within them. An important non-pesticide control option for fruit flies is the use of natural enemies. This study investigated the role of memory and learning in the host searching behaviour of one such natural enemy, the small wasp, Diachasmimorpha kraussii. This wasp is native to Australia and attacks our most serious fruit fly pest, the Queensland Fruit Fly. This research studied fundamental insect behaviour, but produced specific recommendations for the more effective use of Diachasmimorpha kraussii for sustainable pest management.

Full textAbstract:
Pathological gambling is a maladaptive behaviour associated with diminished self-control over persistent compulsive gambling behaviour despite negative consequences. A significant revision to the clinical perspective of pathological gambling is underway, and the disorder will likely be recognized as a behavioural addiction in the fifth edition of Diagnostic and Statistical Manual of Mental Disorders. However, the neurobiological, cognitive and behavioural processes that drive a ‘behavioural addiction’ are unclear. A series of five studies were conducted to investigate cognitive mechanisms associated with neural and behavioural substrates of addictive processes in disordered gambling. Studies 1 through 3 investigated neurobiological correlates of addiction in individuals with pathological gambling as compared to individuals with cocaine dependence, and as compared to non-addicted healthy controls. Study 1 investigated brain activity associated with anticipatory and consummatory reward processing during slot-machine gambling. Study 2 investigated executive control processes by examining functional brain networks associated with loss-chasing behaviour. Study 3 employed voxel-based morphometry (VBM) to explore alterations in grey-matter volumes in individuals with addictive disorders. Studies 4 and 5 investigated the behavioural substrates of addiction in regular gamblers utilizing emerging and novel research techniques. Study 4 examined continuous hand motion trajectories to explore approach biases and implicit processing. Study 5 employed an adaptive testing methodology to explore the influence of gaming machine preferences on cognitive processes and gambling behaviour. Research identified neurobiological and behavioural substrates of gambling-related beliefs and biases that indicate significant contributions of cognitive mechanisms to the development and persistence of a behavioural addiction. Results suggest addictive disorders may share some common features of anticipatory reward processing and brain structure (Studies 1 and 3), while neural signals associated losing outcomes and decision-making during gambling may be specific to disordered gambling (Studies 1 and 2). Furthermore, cognitive distortions in regular gamblers may influence reinforcement and executive control processes (Study 4), and individual preferences for gaming speed may influence cognitions and behaviour during machine gambling. As additional psychological disorders are being considered for classification as behavioural addictions, and clinicians will be faced with the challenges of treating individuals with these non-substance-related addictive disorders, a better understanding of behavioural addictions, through the study of disordered gambling, will be essential under the new diagnostic framework.

Full textAbstract:
This work explores the evolutionary dynamic exhibited by the trajectory of unfair dismissal law in Britain and Australia. A different comparative evolutionary dynamic is observed in the phase leading up to the enactment of a statutory unfair dismissal scheme and in the period subsequent to enactment. It is argued that the shared common law origin of the legal systems of Britain and Australia masks significant divergence in their respective labour law traditions. Whilst collective laissez-faire in Britain, and conciliation and arbitration in Australia both sought to secure industrial peace, these divergent traditions operated in a manner particular to their jurisdiction in constraining the evolution of a statutory unfair dismissal law. It was only when these traditions underwent severe economic, social and political challenges that they faced a crisis of legitimacy and new ideas for labour law were canvassed. Although occurring over twenty years apart, the breakdown of Britain’s and Australia’s labour law traditions saw the juridification of domestic labour law, with a central reform being the inception of a statutory right protecting against unfair dismissal. Despite emerging from divergent legal traditions and according to different timeframes, the trajectory of unfair dismissal law subsequent to its enactment was to converge upon a common theme of peeling back the statutory superstructure in favour of localised and alternative dispute resolution. Although these developments are diachronistic across the two jurisdictions, this evolutionary dynamic of divergence giving way to convergence is revealing of a high degree of path dependency as between the unfair dismissal laws of Britain and Australia.

Full textAbstract:
This thesis examines why the cult of the sovereign goddess was considered important for the expression of royal power in mediaeval India. In literature and ritual, the goddess was conceptualized as the sovereign of heaven and earth. Her cult was heroic because it was primarily a cult of warriors: a good hero was one who worshipped the goddess for great powers, foremost among them being sovereignty. Certain ritual practices of the cult such as self-mutilation formed the criteria for a warrior- worshipper’s heroism. By assessing the available epigraphical, literary, scriptural and anthropological material, I will attempt to show that the association between Indic kingship and the cult’s belief-systems, also referred to as heroic Śāktism, was indeed an ancient one. Tracing its roots to non-Aryan religion, the cult of the sovereign goddess became a vital part of the Sanskritic kingdom, particularly from the latter half of the 6th c., when tribal kingdoms began to elevate themselves on the political map. One of the hallmarks of the cult, responsible for its pan-Indic popularity, was its syncretic nature: besides outcastes, its followers were from a number of sects. The goddess at its centre had no fixed identity but was formed of various personalities. The more public and well-attested of these was the martial goddess Durgā/Caṇḍī/Caṇḍikā, although other goddesses were also worshipped as her other aspects. In all these aspects the sovereign goddess was believed to grant the power of the king and the community. This idea was evoked in the mediaeval Indic world in an array of symbols: sacred statues, ritually empowered swords and insignia put on display for all to see, legends circulated throughout the kingdom, festivals where the sacred might of the realm was ritually reinforced. By assessing these symbols, I will attempt to show the vibrant forms whereby the connection of the cult with power was manifested in the mediaeval period.

Full textAbstract:
Many applications in engineering, computer science and economics involve mixed-integer optimal control problems. Solving these problems in real-time is a challenging task because of the explosion of integer combinations to evaluate. This thesis focuses on the development of new algorithms for mixed-integer programming with an emphasis on optimal control problems of fast dynamical systems with discrete controls. The first part proposes two reformulations to reduce the computational complexity. The first reformulation avoids integer variables altogether. By considering a sequence of switched dynamics, we analyze the switching time optimization problem. Even though it is a continuous smooth problem, it is non-convex and the cost function and derivatives are hard to compute. We develop a new efficient method to compute the cost function and its derivatives. Our technique brings up to two orders of magnitude speedups with respect to state-of-the-art tools. The second approach reduces the number of integer decisions. In hybrid model predictive control (MPC) the computational complexity grows exponentially with the horizon length. Using approximate dynamic programming (ADP) we reduce the horizon length while maintaining good control performance by approximating the tail cost offline. This approach allows, for the first time, the application of such control techniques to fast dynamical systems with sampling times of only a few microseconds. The second part investigates embedded branch-and-bound algorithms for mixed-integer quadratic programs (MIQPs). A core component of these methods is the solution of continuous quadratic programs (QPs). We develop OSQP, a new robust and efficient general-purpose QP solver based on the alternating direction method of multipliers (ADMM) and able, for the first time, to detect infeasible problems. We include OSQP into a custom branch-and-bound algorithm suitable for embedded systems. Our extension requires only a single matrix factorization and exploits warm-starting, thereby greatly reducing the number of ADMM iterations required. Numerical examples show that our algorithm solves small to medium scale MIQPs more quickly than commercial solvers.

Composing is well-embedded into statutory classroom music in English schools and Information and Communications Technology (ICT) has played an Increasing role in this activity. How ICT affects the composing process and the ways in which teaching and learning might need to change to make the most of the technology's potential are, however, not well understood. Extending the view that creativity is a normal feature of human existence to composing in the classroom, this thesis considers ICT to be a means for pupils to realise their potential without having acquired formal theoretical and practical musical skills.

Full textAbstract:
When an out of hospital cardiac arrest (OHCA) occurs, time is of the utmost importance. For every minute that the arrest goes untreated, the chance of survival decreases rapidly. The most common treatment, that is also the most known, is Cardiopulmonary Resuscitation (CPR). Thanks to new technology, the defibrillator is no longer a tool only available to hospital personnel but to anyone who knows where they are located. The objective of this thesis is partly to visualize OHCA occurrences as well as visualize the differences in OHCA occurrences between locations and years. The thesis will analyze where the optimal locations of AEDs are based on a number of variables such as location and year, which is referred to as risk analysis. The analysis was performed by using daytime and nighttime population data from Statistics Sweden (SCB) in combination with heart disease statistics from the national patient register of Socialstyrelsen as well as socio-economic data from SCB. Along with that data, AED locations at the end of 2013 and OHCA data from 2006 up until 2013 was used in visualizations and risk analysis. In order to determine the final optimal placement through the risk analysis, a Geographical Information System (GIS) tool named Multi-Criteria Evaluation (MCE) was used. This tool enabled the weighting of the different parameters against each other, which was integral for the final result. In order to visualize differences, e.g. between two years, a raster was created which consisted of a density difference between the two years. This analysis method shows the spots where there is a majority of either case, e.g. if one area had a larger number of OHCA cases one year compared to previous year. Simple plots were included to show an overview of the problem e.g. where OHCA occurred between the years 2006 and 2013. The results implied that the recommended locations of AEDs while using daytime population data were located in commercial areas. Recommended AEDs from using the nighttime population data was located differently but was located as well as clusters in residential areas. A large source of error in the analysis was the prior heart disease data. The chosen method, an assignment of a percentage chance of heart disease per age group, is a rough and inexact approximation of the actual heart disease statistics. Had there been data about exactly where patients with prior heart disease live and work, the results would most likely be even better.När ett hjärtstopp utanför sjukhus (OHCA) inträffar, är tiden av yttersta vikt. För varje minut som hjärtstoppet går obehandlat minskar snabbt chansen för överlevnad. Den vanligaste behandlingen, som även är den mest kända, är hjärt- och lungräddning. Tack vare ny teknik är defibrillatorn inte längre ett verktyg som endast är tillgänglig för sjukvårdspersonal utan för alla som vet var de finns. Syftet med denna uppsats är att delvis visualisera förekomsten av OHCA men även att åskådliggöra skillnaderna mellan platser och år. I studien analyseras även, baserat på ett antal variabler, var de optimala platserna för Automatiska Externa Defibrillatorer (AED) är. Denna del av analysen är benämnd som riskanalys. Analysen genomfördes med hjälp av att använda dag- och nattidsbefolkningsdata från Statistiska Centralbyrån (SCB) i kombination med hjärtsjuksdomsstatistik från Socialstyrelsens nationella patientsregister och även socioekonomiska data från SCB. Dessa data, samt AED data från slutet av 2013 och OHCA data daterat från 2006 till 2013 användes både till visualiseringen och till riskanalysen. För att bestämma de slutgiltiga optimala platserna genom riskanalysen användes ett Geografiskt Information System (GIS) verktyg som heter multikriterieanalys (MCE). Detta verktyg gör det möjligt att vikta de olika parametrarna mot varandra, vilket var väsentligt för det slutgiltiga resultatet. För att kunna visualisera skillnader, till exempel mellan två år, skapades ett raster som bestod av en densitetskillnad mellan de två åren. Denna analysmetod kunde sedan visualisera var det finns en majoritet av det ena fallet, till exempel om ett område hade fler hjärtstopp ett år jämfört med tidigare år. Enklare kartor användes för att ge en översikt, till exempel var OHCA har skett mellan åren 2006 och 2013. Resultatet tyder på att de rekommenderade platserna för AED då dagtidsbefolkningsdata användes hamnade i områden med många arbetsplatser. De optimala platserna för AED med nattidsbefolkningsdata var annorlunda utplacerade men hamnade även dem i kluster i befolkningstäta områden med mycket bostäder. En av de större felkällorna i analysen tros vara hjärtsjuksdomsstatistiken. Den metod som användes var att extrahera ålder- och könsgrupper från ett patientregister vilket är en grov och inexakt approximation av den faktiska hjärtsjuksdomsstatistiken. Hade tillgång till data om var befolkning med hjärtsjukdomar faktiskt bor och arbetar funnits, kunde resultatet blivit mer pålitligt.

Para conseguirem se alimentar com sucesso, os mosquitos hematófagos possuem componentes em sua saliva capazes de regular a hemostasia e modular a imunidade dos hospedeiros. Entretanto, a avaliação das atividades biológicas dessas moléculas no hospedeiro ainda carece de estudos mais aprofundados. No presente projeto, propomos caracterizar as atividades biológicas do produto do transcrito AET-7393, uma serpina presente nas glândulas salivares de fêmeas do mosquito Aedes aegypti. Nossos dados mostram que a serpina AET-7393 recombinante provoca um aumento no sangramento quando inoculada em camundongos, mas aparentemente esse efeito não está ligado à interferência com a cascata de coagulação. Mostramos ainda que a AET-7393 é capaz de inibir a proteinase 3 e aumentar a produção de IL-1b. Por fim, observamos a ausência de capacidade moduladora sobre a ativação de macrófagos ou sobre a inflamação, e que presença de anticorpos específicos contra a serpina no hospedeiro não interfere no ciclo de vida do mosquito.In order to successfully feed, hematophagous mosquitoes possess salivary components capable of regulating hemostasis and modulate the host immunity. However, the evaluation of the biological activities of the salivary molecules in the host still needs further investigation. In this study, we intend to characterize the biological activities of the AET-7393, a serpin that is present in the saliva of the females Aedes aegypti mosquitoes. Our data show that the recombinant AET-7393 serpin increases bleeding when inoculated in mice, but apparently this effect is not due to its interference on the coagulation cascade. In addition, AET-7393 is able to inhibit proteinase 3 and enhance the production of IL-1b. Finally, we observed the absence of modulatory effect on macrophage activation or inflammation, and that the presence of host anti-AET-7393 antibodies does not interfere in the life cycle of the mosquitoes.

Full textAbstract:
Our understanding of the Later Stone Age (LSA) on the Greater Mapungubwe Landscape has until now been fairly limited. However, it is a landscape upon which foragers witnessed and partook in agriculturalist state formation between AD 900 and 1300, altering their cultural behaviour to suit their changing social and political topography. Nowhere else in southern Africa were foragers part of such developments. For this project a landscape approach was used to study the various changes in the regional LSA record as well as the way in which foragers interacted with farmers. In order to address these issues, data were obtained from an archaeological survey followed by an excavation of seven sites in north-eastern Botswana, part of the Greater Mapungubwe Landscape. These finds indicate that the local forager record varies chronologically and spatially, which had not previously been recorded. Foragers also used a variety of site types and in each a different forager expression was deposited, providing indications of their changing settlement pattern. Notably, this included a gradual movement into agriculturalist homesteads beginning by at least AD 1000 and concluding by AD 1300, when the Mapungubwe capital was abandoned. Thus, interactions, at least in some cases, led to assimilation. There is also clear evidence of exchange with agriculturalists at many of the excavated sites, but this does not always seem to be related to their proximity with one another. Performing a landscape study has also made it possible to make two general conclusions with regard to LSA research. First, these data challenge ethnography, displaying its limitations particularly with linking modern Bushman practices, such as aggregation and dispersal patterns or hxaro gift exchange, to LSA foragers. Second, a full landscape understanding combines the archaeology of multiple cultural landscapes and in this case also crosses national borders, two themes often neglected in southern African archaeological studies.

Full textAbstract:
Responses to the terrorist attacks of September 11, 2001 came in many forms - political, social, cultural, and military. The events of that day shaped the first decade of the 21st century, and continue to have enormous resonance worldwide. This research project examines a particular aspect of the response to September 11 – the literary one, and more specifically, New York fiction. However, in conducting this research it became apparent that the effect of these traumatic events deeply scarred writers, and their writing, and the process of creating fiction about New York was one which was threatened by the enormity of the events. Also, these texts seemed to be in dialogue with other forms of responses to the events in other media. The sense of a community coming together to examine the wound that had been received was strong in New York after the attacks, and that same spirit of coming together could be seen in works that could be labelled as “Post 9/11”. These included comics and graphic novels, artworks, and projects like The Sonic Memorial. This thesis will consider the relationship between these some of works in order to highlight some of the most important aspects of the literary and cultural response. The introduction sets out the historical context and establishes the texts and artworks which will be examined, giving an overview of the research. The first chapter looks at Jonathan Safran Foer’s novel Extremely Loud and Incredibly Close (2005) and Art Spiegelman’s comic In the Shadow of No Towers (2004). It argues that text and image exist in an uneasy relationship in these works, replicating both the lack of comprehension of the events and gaps in memory or expression that emerged through the retelling of the events of September 11. This is one response to the difficulties that come with the attempt to express trauma through narrative, particularly when the political and historical circumstances being described are so complex, and the emotions that surround the event are so raw. The second chapter considers the controversial relationship between performance, art, and acts of terror in Don DeLillo’s novel Falling Man and Gerhard Richter’s October 18, 1977 cycle of artworks. The final chapter explores narrative and testimony in Paul Auster’s novel Man in the Dark and The Sonic Memorial Project, which gathered sounds and reminiscences related to the Twin Towers and September 11. The methodology of considering fiction alongside other modes of response is embedded in the structure of the thesis, with each chapter exploring a major novel alongside a related artwork or narrative. This mirrors the cacophonous and varied responses to 9/11, but also captures something of the way in which the reaction to the trauma brought sometimes distinct and separate people, voices and perspectives together in the spirit of sharing experiences and perspectives. It is concluded that the act of creating a piece of literature, artwork, or another kind of narrative, about September 11 is often confronted by the traumatic nature of the events, and that many responses to them internalised this problem, becoming as much about the nature of trauma, and how it makes certain memories and thoughts extremely difficult to express, at least in a way that is equal to the emotion involved. September 11 poses a challenge to artists that is much wider than the problem of representing the event itself. It asks artists and writers to consider how one can represent a traumatic and widely witnessed event, and whether world-changing events require an upheaval of literary and artistic conventions. It also questions the role of the writer or artist in the face of what Don DeLillo described as ‘all that howling space’. The thesis concludes that the strategy employed by most of the works examined here is to use unconventional methods to construct a memorial to those lost, but to do so in a way that involves the reader, bringing them into the events, but also pointing to the process of creating a post-9/11 artwork, and the difficulties inherent in it. This maintains the long established tradition of metafiction in New York fiction, demonstrating that these are works that do not seek a complete break with the past, but bring a new raw edge of tragedy and trauma into the metafiction. In this way formal play, and the attention to the process of creating a text or artwork becomes a means of representing the trauma of the event, and the trauma of creating literature and art about it. The metafictional aspects therefore become a means of cathartically approaching the site of the wound. This is perhaps why so much post 9/11 fiction remains either controversial or divides critics. It looks at both the event and its own processes. Whether or not this is satisfying to the reader, or the critic, it does point to the anxieties felt by writers and the wider creative community in the wake of 9/11.

Full textAbstract:
Construction productivity is one of the most frequently researched topics due to its importance to the viability of the industry. It is regarded as a true reflection of the efficiency and economic success of the operations.Despite the plethora of research into construction productivity reported over the years, a thorough examination of the literature revealed a dearth of research into the influence of buildability factors, i.e.design variables, on the labour productivity of one of the most important materials in the construction industry; in situ reinforced concrete.According to the Construction Industry Research and Information Association (CIRIA), buildability is defined as "the extent to which the design of a building facilitates ease of construction, subject to the overall requirements for the completed building". Apart from the Singaporean Buildable Design Appraisal System (BOAS), which suffers from major shortcomings, to date, no comprehensive study was conducted to investigate and quantify the effects and relative influence of architectural and structural buildability factors on the labour productivity of in situ reinforced concrete buildings. In this project, the major buildability factors hypothesised to influence the labour productivity of the main trades, i.e. formwork, reinforcing steel fixing, concreting and finishing, included grid patterns of footings and columns, type of structural framing system, geometry and dimensions of elements,height of floors, the degree of design rationalisation, standardisation and repetition of elements, reinforcing steel quantity and diameters, location and congestion of reinforcement, volume and workability of concrete as well as surface finish.In addition, and due to its importance to the productivity of the construction industry, the effect of the learning curve theory has been the subject of several previous studies. However, a comprehensive investigation of the impact of the learning phenomenon on the major trades associated with in situ reinforced concrete buildings has not been carried out.The raw data were collected from thirty-nine different construction sites in the State of Kuwait, using specifically designed data collection forms for a total period of nineteen months. In order to triangulate the results, productivity data were collected and analysed at both levels; macro and micro. Since several sites were monitored simultaneously, the intermittent observation technique was selected to form the basis for the observation method.Several relevant buildability factors impact the labour productivity simultaneously. Therefore, to isolate the net effects and quantify the relative influence of these factors on labour productivity, linear regression was used for the statistical analysis throughout this research project. As a result, it was possible to quantify the relationship between labour productivity and the following buildability factors: a) footings and columns grid pattern; b) formwork area; c) variability of elements size; d) geometry of elements, i.e. circular versus rectangular columns, curved versus linear beams, non-rectangular versus rectangular slabs, and number of angles around the perimeter of slabs and walls; e) number of beams used to support the floor area; n number of beam intersections in the framing system; g) dimension of elements; h) reinforcing steel bar diameter; i) quantity of reinforcement fixed; j) location and congestion of reinforcement; k) volume and workability of concrete; I) height of floors above the ground level; and m) power- trowelled floor finish.The applicability of learning curve theory to formwork, reinforcing steel fixing and pumped concrete was investigated using the unit straight-line model. Due to the negative impact of height on pumped concrete productivity, the effect of learning on this trade could not be determined. On the other hand,the effect of the learning phenomenon on formwork and reinforcing steel fixing labour productivity was insignificant suggesting no potential context for the theory to be used as a useful tool to quantify the productivity improvement, allocate resources or schedule activity durations.This research project has quantified the relationship between the principal design characteristics of in situ reinforced concrete construction and labour productivity of the various trades involved. It can provide practical guidance to architects and structural designers who seek to optimise their designs.In addition, it can give a feedback on how well the designed building considers the requirements of the basic buildability principles and provides for tangible consequences of their design decisions on the construction labour productivity.

This doctoral thesis is a practice-led enquiry into the value of 3-D Computer Generated Imagery (CGI) in the visualisation and animation of clinical radiological scan data. The aim of this work is to develop an alternative pathway to visualising clinical data that augments and challenges the existing medical imaging aesthetic. It questions the integrity of the author?s arts-based interpretation of the radiological scan data and its relevance in the realworld context of enhancement of doctor-patient communication and interaction.The thesis starts by exploring current pathways for visualising the inner body, in particular biomedical animation, TV documentary, clinical 3-D visualisation and fine art practice inmedical imaging. This analysis is followed by an interrogation of the literature in the field of doctor-patient interaction, resulting in a small qualitative study with patients. This helps to define the opportunity for a new visualisation pathway that brings together the visual and narrative approaches of a 3-D computer animation aesthetic and the detail embedded inclinical radiological scan data.A multi-method approach is used to address the research questions. Informed by a collaborative two-year residency at Ninewells Hospital, NHS Tayside, Dundee, the author creates a series of 3-D CGI works that define this hybrid visualisation pathway. The resulting bandwidth of interpretative works is then investigated in a qualitative study involving semistructured interviews with professionals from the arts and clinical imaging. Overall, the study suggests that image integrity is tethered to context and purpose, contextualising the potential application of the author?s 3-D CGI works. The author concludes that his original contribution to knowledge is this alternative visualisation pathway, as developed through thebandwidth of interpretation. This is achieved through the exposition and use of the author?s tacit knowledge, and the collaborative approach. This provides a transferable model ofworking, for the future visualisation of medical scan data.

Full textAbstract:
This thesis aims to determine the constitutional implications of the exclusive authority granted to the CJEU to interpret the Treaties in the context of the internal market. In particular, it examines how the Court's interpretation of the free movement and competition rules - the two principal components of the internal market law - has shaped the constitutional division of competences between the EU and the Member States (the vertical dimension) and between the EU's legislative institutions and the Court (the horizontal dimension). The argument to be advanced in this thesis is based on a comparative analysis of the Court's reasoning in cases involving conflicts between, on the one hand, the free movement and competition rules and, on the other, domestic regulatory measures that embody various social policy considerations. The policy areas selected as case studies for the inquiry are healthcare, education, collective labour law, and gambling. None of these areas has been harmonised at EU level, save for the legislation essentially codifying the case law, and therefore come within the purview of EU law mainly through the judgments of the Court adopted in the context of the internal market. The comparative analysis - both among the selected policy areas and between the Court's free movement and competition case law - reveals the inconsistencies in the Court's exercise of its interpretative authority in light of the principles that govern the division of competences and powers in the EU. The thesis ultimately argues that, unlike its competition case law, the Court's free movement case law involving the areas of healthcare, education and collective labour law, but not gambling, has encroached on national regulatory autonomy to an extent incompatible with the principles of conferral, subsidiarity and proportionality, and has reduced the scope of EU legislative action to the point of upsetting the institutional balance of powers between the EU's judiciary and legislature.

Full textAbstract:
Out-of-hospital cardiac arrest (OHCA) has become a leading cause of death in Sweden, while the useful tool external defibrillator (AED), which enables the heart to restart to beat, is not fully used. Prior studies have worked out various solutions to promote the use of AEDs. However, those studies only delved into the situation in certain areas but barely fit the conditions in Sweden. In addition, few of the studies explored the cause of low use of AEDs from the perspective of users. This work investigated the drawbacks in the current situation in Sweden and users’ thoughts towards using AEDs. As a result, this thesis presented a persuasive design, a group of embedded functions in Google Maps. The main effects of the design are: 1. Endowing bystanders with knowledge of where AEDs are located and how to manage the device 2. Facilitating the process of seeking and retrieving the devices and creating a channel for bystanders to sought help. The prototype was further evaluated through Heuristic Evaluation. The study results showed the design successfully made a persuasive impact on bystanders to change their attitudes by offering instruction for them to seek and control AEDs. The design also remedied deficiencies in the current situation of using AEDs in Sweden. Lastly, the study concluded persuasive design can play a role to facilitate the use of AEDs, thus improving the survival rate of OHCAs.

Full textAbstract:
This wok presents a study about approaches dealing with Design For X (DFX), with emphasis on Design For Environment, specifically the Design For Recycling and Design For Disassembly. This study is justified by the necessity to consider the environmental demands in the production setor as well as the social demands and the information needed by the designers in the stage of product development. This research shows that the products are designed considering only the building process. Having the environmental questions in mind, the designers need to also consider how to dismantle those products to make the recycling possible. Various methods to analyze the project deficiencies of the product have been described in the literature. The majority of the methods are quantitative or computer simulation, and do not take into consideration the real activity of the recycling workers. The proposal of this research is to use a qualitative method in an analytical situation of
manual disassembly for product recycling in the Brazilian reality. The Work Ergonomic Analysis (WEA) emerges as a helpful methodology for the Environmental Project to evaluate the difficulties of products disassembly that interfere in the recycling. This study was performed at the Association of Collectors of Paper, Cardboard and Reusable
Materials (Asmare), and has its focus in the analysis of the disassembly of containers made of Polyethylene terepthalate (PET). It is demonstrated that the analysis of the difficulties derived from the activities of disassembly of materials supplies means to identify the product characteristcs defined during its design stage that interfere with the
recycling process. It is also seen that the problems encountered, in the deismantling of materials, included those of efficiency and the increase in work load as well as the risk of accidents. Therefore, the strategies of disassembly and the work conditions of those involved in these design.This will have benefits for the workers, the recycling companies, industries and to the environment.At the end of the analysis, investigations were made in factories that use PET containers
and in some factories of PET components, to obtain information about the week points of the process from the viewpoint of Design For Recycling. The investigations demonstrate that the factories did not withhold konowledge of the difficulties that the products give to the recycling workers. Thus, the hypothesis of this thesis is confirmed that the WEA can contribute to the designers to give them information about
the deficiencies for the project of materials from the viewpoint of Design For Recycling.Este trabalho apresenta um estudo sobre abordagens do Design for X (DFX), enfatizando o Projeto para Meio Ambiente, especificamente o Projeto para Reciclagem, e o Projeto para Desmontagem. O estudo se justifica pela necessidade de considerar a demanda ambiental no setor produtivo, a demanda social e a demanda de informação ao projetista na etapa do desenvolvimento de produto. Verifica-se que os produtos são projetados considerando-se apenas as operações de montagem. Tendo em vista as questões ambientais, os projetistas necessitam observá-los também em termos de desmontagem para viabilizar a reciclagem. Ainda assim, vários métodos para analisar as deficiências de projeto do produto têm sido descritos na literatura, sendo a maioria quantitativos ou simulações feitas por computador, não levando em consideração a atividade real dos trabalhadores da reciclagem. Com este trabalho propõe-se utilizar um método qualitativo em uma situação de análise de desmontagem manual para a reciclagem do produto, inserido na realidade brasileira.A Análise Ergonômica do Trabalho (AET) é sugerida como metodologia de apoio ao Projeto para Meio Ambiente, para avaliar as dificuldades na desmontagem do produto que interferem na reciclagem. Este estudo foi realizado na Associação de Catadores de Papel,Papelão e Materiais Reaproveitáveis (Asmare) e teve como foco a análise da desmontagem da embalagem Politereftalato de Etileno (PET).Demonstrou-se que a análise das dificuldades derivadas da atividade da desmontagem do produto fornece meios para identificar as características do produto, definidas em projeto, que interferem na reciclagem. Verificou-se, também, que as dificuldades encontradas para a desmontagem do produto levam a problemas quanto à eficiência e ao aumento da carga de trabalho, bem como a riscos de acidentes. Portanto, as estratégias de desmontagem e as condições de trabalho dos envolvidos nestes processos devem ser levadas em consideração na fase inicial do projeto do produto, o que trará benefícios aos trabalhadores, aos recicladores, às indústrias e, em última análise, ao próprio meio ambiente.Ao final da análise, foram feitas investigações em fábricas que utilizam a embalagem PET e em alguns fabricantes de seus componentes, para obter informações sobre os pontos fracos do produto do ponto de vista do Projeto para reciclagem. As investigações demonstraram que os fabricantes não detêm conhecimentos sobre as dificuldades que seus produtos oferecem aos trabalhadores da reciclagem. Dessa forma, confirma-se a hipótese desta tese de que a AET pode contribuir com os projetistas, fornecendo-lhes informações sobre as deficiências de projeto do produto, do ponto de vista do Projeto para Reciclagem.

Full textAbstract:
Commercial aviation has become an integral part of modern society and enables unprecedented global connectivity by increasing rapid business, cultural, and personal connectivity. In the decades following World War II, passenger travel through commercial aviation quickly grew at a rate of roughly 8% per year globally. The FAA's most recent Terminal Area Forecast predicts growth to continue at a rate of 2.5% domestically, and the market outlooks produced by Airbus and Boeing generally predict growth to continue at a rate of 5% per year globally over the next several decades, which translates into a need for up to 30,000 new aircraft produced by 2025.
With such large numbers of new aircraft potentially entering service, any negative consequences of commercial aviation must undergo examination and mitigation by governing bodies so that growth may still be achieved. Options to simultaneously grow while reducing environmental impact include evolution of the commercial fleet through changes in operations, aircraft mix, and technology adoption. Methods to rapidly evaluate fleet environmental metrics are needed to enable decision makers to quickly compare the impact of different scenarios and weigh the impact of multiple policy options.
As the fleet evolves, interdependencies may emerge in the form of tradeoffs between improvements in different environmental metrics as new technologies are brought into service. In order to include the impacts of these interdependencies on fleet evolution, physics-based modeling is required at the appropriate level of fidelity. Evaluation of environmental metrics in a physics-based manner can be done at the individual aircraft level, but will then not capture aggregate fleet metrics. Contrastingly, evaluation of environmental metrics at the fleet level is already being done for aircraft in the commercial fleet, but current tools and approaches require enhancement because they currently capture technology implementation through post-processing, which does not capture physical interdependencies that may arise at the aircraft-level.
The goal of the work that has been conducted here was the development of a methodology to develop surrogate fleet approaches that leverage the capability of physics-based aircraft models and the development of connectivity to fleet-level analysis tools to enable rapid evaluation of fuel burn and emissions metrics. Instead of requiring development of an individual physics-based model for each vehicle in the fleet, the surrogate fleet approaches seek to reduce the number of such models needed while still accurately capturing performance of the fleet. By reducing the number of models, both development time and execution time to generate fleet-level results may also be reduced.
The initial steps leading to surrogate fleet formulation were a characterization of the commercial fleet into groups based on capability followed by the selection of a reference vehicle model and a reference set of operations for each group. Next, three potential surrogate fleet approaches were formulated. These approaches include the parametric correction factor approach, in which the results of a reference vehicle model are corrected to match the aggregate results of each group; the average replacement approach, in which a new vehicle model is developed to generate aggregate results of each group, and the best-in-class replacement approach, in which results for a reference vehicle are simply substituted for the entire group. Once candidate surrogate fleet approaches were developed, they were each applied to and evaluated over the set of reference operations. Then each approach was evaluated for their ability to model variations in operations. Finally, the ability of each surrogate fleet approach to capture implementation of different technology suites along with corresponding interdependencies between fuel burn and emissions was evaluated using the concept of a virtual fleet to simulate the technology response of multiple aircraft families.
The results of experimentation led to a down selection to the best approach to use to rapidly characterize the performance of the commercial fleet for accurately in the context of acceptability of current fleet evaluation methods. The parametric correction factor and average replacement approaches were shown to be successful in capturing reference fleet results as well as fleet performance with variations in operations. The best-in-class replacement approach was shown to be unacceptable as a model for the larger fleet in each of the scenarios tested. Finally, the average replacement approach was the only one that was successful in capturing the impact of technologies on a larger fleet.
These results are meaningful because they show that it is possible to calculate the fuel burn and emissions of a larger fleet with a reduced number of physics-based models within acceptable bounds of accuracy. At the same time, the physics-based modeling also provides the ability to evaluate the impact of technologies on fleet-level fuel burn and emissions metrics. The value of such a capability is that multiple future fleet scenarios involving changes in both aircraft operations and technology levels may now be rapidly evaluated to inform and equip policy makers of the implications of impacts of changes on fleet-level metrics.

The concern over undergraduate engineering students’ mathematical skills and the means of addressing this through the provision of mathematics support is the main driver of this research. With the emergence of mathematics support within mathematics education there has been an associated research community interested in measuring the effectiveness of mathematics support provision. Recent studies have measured improvements in mathematics performance for students who have used mathematics support against those who have not by comparing prior mathematical ability against examination results. This does not address the issue of individual differences between students and resulting changes in mathematical ability. However the provision of mathematics support for individual students is resource intensive hence evaluation of the effectiveness of the support is essential to ensure resources are efficiently used. This mathematics education research examines the effectiveness of mathematics support in addressing the mathematics problem. It does this by considering individual differences and the mismatch of mathematical skills for studying at University by analysing the effectiveness of mathematics support in improving mathematical skills. The dataset for the analysis comprises of over 1000 students from a Scottish Post-92 University, over 8% having made use of mathematics support, and nearly 2000 students from an English Russell Group University, with just over 10% having made use of the support. It was discovered that in both sets of data the students who came for mathematics support in comparison to their peers had a statistically significant lower mathematical skills base on entry to their course, and at the end of their first year had improved their mathematical skills base more than their counterparts. Although the analysis is based on data from UK Universities we believe the findings are relevant to the international community who are also engaged in the provision of mathematics support.

The purpose of this study is to explore the contemporary social phenomenon of soft ASB in tourism, specifically in Andalucia, Spain. A series of observations, interviews with tourists and hosts and focus groups were conducted during the period of two tourist seasons. The aim was to establish the types of ASB exhibited by UK leisure tourists and to explore the reasons for the ASB exhibited. A qualitative approach to research was adopted and data were analysed and interpreted following the constant comparison method. Findings show that soft ASB exists in Andalucia. However, tourist and host perceptions of ASB were different. For the tourists ASB focused on the drinking culture of the UK leisure tourist. For the host ASB constituted reluctance by the British to embrace Spanish culture demonstrated through, for example, a preference by the tourist to consume British style food rather than Spanish. ASB is notoriously difficult to define and to date has not been defined in tourism. For this study a fresh definition has been created based on the findings of this study. This has taken into account the broader context of ASB and the reasons for ASB. This study has developed a framework that establishes management responses to and management implications of ASB in a cross-cultural tourism context and which suggests a practical and theoretical approach to ASB. Whist the findings are not considered to be generalisable the framework and qualitative research approach could be adopted for investigations into a range of tourist behaviour.

The driving factor behind this research was to design & develop a line driver capable of meeting the demanding specifications of the next generation of SerDes devices. In this thesis various line driver topologies were analysed to identify a topology suited for a high-speed low-voltage operating environment. This thesis starts of by introducing a relatively new high-speed communication Device called SerDes. SerDes is used in wired chip-to-chip communications and operates by converting a parallel data stream in a serial data stream that can be then transmitted at a higher bit rate, existing SerDes devices operate up to 12.5Gbps. A matching SerDes device at the destination will then convert the serial data stream back into a parallel data stream to be read by the destination ASIC. SerDes typically uses a line driver with a differential output. Using a differential line driver increases the resilience to outside sources of noise and reduces the amount of EM radiation produced by transmission. The focus of this research is to design and develop a line driver that can operate at 40Gbps and can function with a power supply of less than IV. This demanding specification was decided to be an accurate representation of future requirements that a line driver in a SerDes device will have to conform to. A suitable line driver with a differential output was identified to meet the demanding specifications and was modified so that it can perfonn an equalisation technique called pre-distortion. Two variations of the new topology were outlined and a behavioural model was created for both using Matlab Simulink. The behavioural model for both variants proved the concept, however only one variant maintained its perfomance once the designs were implemented at transistor level in Cadence, using a 65nm CMOS technology provided by Texas Instruments. The final line driver design was then converted into a layout design, again using Cadence, and RC parasitics were extracted to perfom a post-layout simulation. The post layout simulation shows that the novel line driver can operate at 40Gbps with a power supply of 1 V - O.8V and has a power consumption of 4.54m W /Gbps. The Deterministic Jitter added by the line driver is 12.9ps.

Previous issue date: 2009O presente trabalho tem o objetivo de fazer uma investigação para responder a seguinte questão de pesquisa: como melhorar a motivação de enfermeiros que trabalham na área de saúde hospitalar, em condições insalubres de trabalho, alto grau de estresse, grande responsabilidade no sucesso do tratamento médico, rápidos avanços tecnológicos, trabalho padronizado e coletivo? e de propor um modelo motivacional para esses profissionais com os dados das pesquisas teóricas e de campo. A pesquisa de campo foi realizada em três hospitais particulares de Recife, com a utilização de entrevistas com gerentes de recursos humanos. Constatou-se que, a equipe de enfermagem dos hospitais escolhidos necessita de uma melhor remuneração, treinamento, retreinamento e uso de novas tecnologias. Verifica-se, também, que a se fazem indispensáveis algumas ações para obtenção de uma maior autonomia na execução de sua função, em virtude desse profissional assumir a coordenação da equipe de enfermagem. Esses fatores estimulariam a motivação dos enfermeiros para um melhor desempenho no trabalho, obtendo uma melhor qualidade dos serviços prestados. Na construção do modelo motivacional optou-se pela aplicação dos conceitos motivacionais da Teoria ERG e da Teoria da Fixação de Objetivos, utilizando a ergonomia organizacional, com a metodologia da Análise Ergonômica do Trabalho AET, para a fase de diagnóstico das necessidades dos enfermeiros

Previous issue date: 2003-01-01The need to access public or private institutions has long existed. Of our interest, is the measure of efficiency among different departments of a public university. Unlike most private universities; a public university does not focus on teaching, as it is only output. Together with this, public universities produce knowledge as a whole, in the form of research (with the development of new technologies) and extension activities. The diverse character of production demands mathematical methods to quantify efficiency, point out deficiencies related to specific output (or input) measures and provide targets. Data Envelopment Analysis (DEA) is proposed to access the efficiency of the departments of the Universidade Federal de São Carlos UFSCar . To apply DEA, many production indicators were generated from data available from the year 2001. A general efficiency classification of all thirteen departments of UFSCar in relation to seven measures of production in the fields of teaching, research and extension activities, and two measures of resources was obtained. In addition, individual classifications were obtained by considering a field at a time or considering related sets of departments belonging to a given center. The incompleteness of precise data was a limiting factor in this analysis, hampering, in some cases, the obtainment of a realistic image of efficiency. In this way, the results showed here, must be seem with caution, a must be used only as a reference on the understanding of the difficulties associated with the complex task of efficiency assessment and target establishment.
Há muito tempo existe uma necessidade em avaliar o desempenho nas instituições públicas ou privadas. O objetivo deste trabalho, é a avaliação de eficiência de departamentos de uma universidade pública. Ao contrário da maioria das universidades privadas, a universidade pública não foca apenas no ensino como única produção. Somado a isto, a universidade produz conhecimento como um todo, na forma de pesquisa (com o desenvolvimento de novas tecnologias) e atividades de extensão. A diversidade de produção destas universidades exigem o uso de ferramentas matemáticas, capazes de quantificar a eficiência produtiva dos departamentos que a constituem, de forma a auxiliar na detecção de deficiências específicas para o estabelecimento de metas. A Análise de Envoltória de Dados (AED) é uma ferramenta proposta neste trabalho, para avaliar a eficiência dos departamentos da Universidade Federal de São Carlos UFSCar. Para a aplicação da AED, vários indicadores de produção foram gerados a partir de dados referentes ao ano de 2001. Uma classificação geral de todos os trinta departamentos da UFSCar, em relação a sete indicadores de produção nas áreas de ensino, pesquisa e extensão, e dois indicadores de recursos foi obtido. Somado a isto, classificações individuais foram obtidas considerando uma área por vez, ou considerando conjuntos de departamentos relacionados pertencendo a um mesmo centro. A ausência de dados completos e precisos foi um fator limitante na análise, impedindo em alguns casos, a obtenção de um panorama realista a respeito da eficiência. Desta forma, os resultados apresentados aqui, devem ser vistos com cautela, devendo ser utilizado apenas como referência no entendimento das dificuldades associadas à complexa tarefa de avaliação de eficiência e determinação de metas.

Full textAbstract:
IoT devices are increasingly used in the process of gathering scientific data. In environmental monitoring IoT devices can be used as remote sensing devices to collect information about e.g. temperature. To keep data reliable, various security aspects have to be considered. Constrained devices are limited by memory size and battery life, a security solution has to be developed with this in mind. In this study an IoT security solution was developed in collaboration with a research group in environmental science at Umeå University. We selected commonly used algorithms and compared them with the goal to provide authentication and integrity for an IoT application, while minimizing energy use running on an Atmega 1284P. The results showed that the encryption algorithm AES-256-GCM is a good choice for a total security solution. AES-256-GCM provides authenticated encryption with additional data while, in relation to the other tested algorithms, using energy at a low level and leaving a small program size footprint.

Full textAbstract:
Job satisfaction is a topic that garners quite a lot of attention in the literature as researchers and practitioners alike seek to understand, predict and improve employees’ contentment with their jobs. Similarly, in the decade and a half since its introduction, affective events theory (AET, Weiss & Cropanzano, 1996) is also gaining attention as it is recognized as a theoretically rigorous framework (Humphrey, 2006) and the prominent theory relating to workplace affect (Ashton-James & Ashkanasy, 2005). AET supplies a framework for investigating the relationship between work events, emotions and the resulting attitudes and behaviors – a structure which several investigations have empirically tested. The current paper reviews research conducted on job satisfaction within the AET framework and identifies areas in need of additional investigation.

Cette thèse décrit la circulation du concept d’ion au XIXe siècle. Symbole de revendications unificatrices de la science, il est l’enjeu d’appropriations et de transformations variées. La première partie expose la diversité des approches du problème que pose le phénomène d’électrolyse entre 1800 et 1830. Malgré de profondes divergences théoriques et philosophiques, une culture commune de l’électrochimie s’impose en Europe. La seconde partie traite de la formulation et de l’accueil du concept d’ion dans ce paysage à la fois stable et éclaté. Entre 1834 et la fin des années 1870, les principes ioniques sont inventés, acceptés, rejetés ou transformés par des savants issus de traditions savantes différentes. Le concept d’ion se propage et se transforme particulièrement en territoire savant germanique. La troisième partie décrit la forte augmentation de l’intérêt savant pour l’électrolyse et les ions entre 1880 et les années 1910. La confrontation des idées sur la matière et l’électricité ainsi que des méthodes expérimentales provoquent d’importantes modifications du concept d’ion. Il est désormais l’enjeu de problèmes nouveaux, autres qu’électrochimiques. Une méthodologie originale est proposée dans cette thèse : elle vise à imbriquer les processus épistémiques et sociaux qui régissent l’histoire du concept d’ion. L’objectif est d’en offrir une description complète rompant avec l’historiographie disciplinaireThis dissertation describes the circulation of the concept of ion throughout the 19th century. As a symbol of the claims for the unity of science, it was subject to a diversity of appropriations and transformations. The first part exposes the many approaches of the problem raised by the phenomenon of electrolysis between 1800 and 1830. Despite deep theoretical and philosophical differences, a common culture of electrochemistry emerged in Europe. The second part deals with the coining and reception of the concept of ion in this both stable and heteroclite context. From 1834 to the end of the 1870’s, ionic theories were invented, accepted, rejected or transformed by men who were influenced by different scientific traditions. German scientists particularly spread and transformed the concept of ion. The third part describes the spectacular rise of interest the concept of ion and electrolysis benefited between 1880 and the 1910’s. Ideas on matter and electricity and experimental methods collided. It was the cause of important transformations of the concept of ion. The aim of this dissertation is to maintain embedded the epistemic and social aspects that affected the history of the concept of ion

Full textAbstract:
En France, le secteur du bâtiment constitue un enjeu majeur car est responsable à lui seul d'environ la moitié de la consommation d'énergie finale et près du quart des émissions nationales de gaz à effet de serre. Dans ce contexte, les réglementations concernant l’efficacité énergétique des bâtiments amènent les professionnels du bâtiment à s'interroger sur la question de l’isolation du bâti dit « ancien », en particulier, sur le bâti en tuffeau de la vallée de la Loire. Or, il n’existe pas actuellement de réponses technologiques avérées pour la réhabilitation de bâtiments en tuffeau. Dans ce cadre, on privilégiera des solutions techniques innovantes faisant appel au chanvre par deux applications sèche et humide. En effet, des travaux de recherche récents ont souligné la performance hygrothermique intéressante de cet éco-matériau, en outre de son respect à l’environnement et la démarche du développement durable. Dans cette thèse, trois objectifs sont ainsi visés. Le premier, a été axé sur une étude paramétrique du tuffeau et des bétons de chanvre ce qui permettra d’élaborer une base de données regroupant les propriétés nécessaires à l’évaluation de la technique d’isolation et à la modélisation numérique des transferts couplés chaleur/humidité dans les parois. Le deuxième objectif a été de tester les parois isolées sous des conditions d’humidité et de température réelles imposées avec la réalisation d’une cellule biclimatique. Enfin le troisième objectif de ce travail fut de vérifier les résultats expérimentaux aux résultats numériques obtenus par le biais d’un logiciel de simulation bidimensionnel des transferts couplés en milieux poreux (chaleur/humidité – WUFI)In France, the building sector is a major challenge because alone is responsible for about half of the final energy consumption and nearly a quarter of national greenhouse gas emissions. In this context, the regulations concerning the energy efficiency of buildings lead professionals to wonder about the issue of the insulation of buildings said “old”, built before 1948, in particular, those of Loire Valley made with tuffeau. However, there are no proven technology answers for the rehabilitation of buildings in limestone. In this context, we preferred use innovative technical solutions using hemp by wet and dry applications. Indeed, recent research has highlighted the interesting hygrothermal performance of this eco-material, in addition to its respect for the environment and sustainable development approach. In this phD work, three objectives are well pointed out. The first focused on a parametric study of limestone and concrete hemp to create a database of properties necessary for the evaluation of the insulation technique and numerical modeling of coupled heat and moisture transfer in the walls. The second objective was to test the insulated walls under real relative humidity and temperature conditions imposed within a biclimatic device. Finally, the third objective was to verify the experimental results with the numerical results obtained through two-dimensional software in porous media (heat / moisture - WUFI)
