Parking is often underpriced and expanding its capacity is expensive; universities need a better way of reducing congestion outside of building costly parking garages. Demand based pricing mechanisms, such as auctions, offer a possible solution to the problem by promising to reduce parking at peak times. However, faculty, students, and staff at universities have systematically different parking needs, leading to different parking valuations. In this study, I determine the impact university affiliation has on predicting bid values cast in three Dutch Auctions of on-campus parking permits sold at Chapman University in Fall 2010. Using clustering techniques crosschecked with university demographic information to detect affiliation groups, I ran a log-linear regression, finding that university affiliation had a larger effect on bid amount than on lot location and fraction of auction duration. Generally, faculty were predicted to have higher bids whereas students were predicted to have lower bids.

La présente étude a pour but de vérifier si le QI et le sentiment de compétence interagissent lorsque l’élève doit performer à l’école et si, en l’occurrence, cette interaction est à son tour modérée par l’âge et le sexe des participants. Afin de vérifier ces hypothèses, les variables suivantes ont été étudiées chez 928 élèves de souche francocanadienne fréquentant des écoles montréalaises de niveau secondaire : la moyenne en mathématiques, le QI, le sentiment de compétence en mathématiques, l’âge, le sexe et le statut socioéconomique. Tel que prévu, le QI et le sentiment de compétence en mathématiques corrèlent de façon positive et significative avec la moyenne en mathématiques de l’élève. Les analyses montrent également une interaction significative entre le QI et le sentiment de compétence. Une fois décomposée, cette interaction indique que chez les élèves qui ont un sentiment de compétence élevé, la valeur prédictive du QI est plus élevée, alors que la relation entre le QI et la performance ne change pas de façon significative chez les élèves qui présentent un faible sentiment de compétence. Enfin, ni l’âge ni le sexe de l’élève n’influencent l’interaction entre le QI et le rendement scolaire, pas plus qu’ils ne sont corrélés avec le rendement scolaire. Les implications cliniques de cette recherche sont discutées.

Particle reactive elements are scavenged to a higher degree at ocean margins than in the open ocean due to higher fluxes of biogenic and terrigenous particles. In order to determine the influence of these processes on the depositional fluxes of 10Be and barium we have performed high-resolution measurements on sediment core GeoB1008-3 from the Congo Fan. Because the core is dominated by terrigenous matter supplied by the Congo River, it has a high average mass accumulation rate of 6.5 cm/kyr. Biogenic 10Be and Ba concentrations were calculated from total concentrations by subtracting the terrigenous components of10Be and Ba, which are assumed to be proportional to the flux of Al2O3. The mean Ba/Al weight ratio of the terrigenous component was determined to be 0.0045. The unusualy high terrigenous 10Be concentrations of 9.1 * 10**9 atoms/g Al2O3 are either due to input of particles with high10Be content by the Congo River or due to scavenging of oceanic 10Be by riverine particles. The maxima of biogenic 10Be and Ba concentrations coincide with maxima of the paleoproductivity rates. Time series analysis of the 10Be and of Ba concentration profiles reveals a strong dominance of the precessional period of 24 kyr, which also controls the rates of paleoproductivity in this core. During the maxima of productivity the flux of biogenic Ba is enhanced to a larger extent than that of biogenic 10Be. Applying a model for coastal scavenging, we ascribe the observed higher sensitivity of Ba to biogenic particle fluxes to the fact that the ocean residence time of Ba is approximately 10 times longer than that of 10Be.

Corporate Social Responsibility (CSR) är i grunden ett företagsbegrepp som på senare år allt mer börjat prägla idrottsvärlden. CSR är ett samlingsbegrepp på aktiviteter som utförs för att främja samhället. Anledningarna till att idrottsföreningar väljer att engagera sig i frågor som berör samhället är många men, inom Sverige har den idrottsliga kommersialiseringen och professionaliseringen bidragit till att elitidrottsföreningar arbetar med CSR-frågor utöver kärnverksamheten. Elitidrottsföreningar skapar stort medialt intresse och supportrar är en av elitidrottsföreningarnas primära intressenter som bidrar till framgång. Alla supportrar har inte samma engagemang eller åsikter i frågor rörande föreningen. Syftet med denna studie är att undersöka svenska elitidrottsföreningars supportrars attityd till CSR-arbete utöver kärnverksamheten samt jämföra om attityden skiljer sig mellan supportrar baserat på supporteridentifikation. För att uppnå syftet gjordes en kvantitativ enkätundersökning av supportrar till Hammarby Fotboll. Av totalt 96 respondenter identifierades 44 med lägre och 52 med högre supporteridentifikation. Resultatet visade att attityden mellan respondentgrupperna skiljde sig på det sätt att den högre identifikationsgruppen lutade åt en negativ attityd samtidigt som den lägre identifikationsgruppen var neutral med en marginell negativ lutning. Studien landade i att skillnaderna var marginella och att båda grupperna tolkas neutrala vilket ger slutsatsen att CSR utöver kärnverksamheten har ringa betydelse för supportrar oavsett identifikation.

To evaluate the effect of sildenafil, administered prior to renal ischemia/reperfusion (I/R), by scintigraphy and histopathological evaluation in rats. Methods: Twenty-four rats were divided randomly into two groups. They received 0.1 ml of 99mTechnetium-etilenodicisteine intravenous, and a baseline (initial) renal scintigraphy was performed. The rats underwent 60 minutes of ischemia by left renal artery clamping. The right kidney was not manipulated. The sildenafil group (n=12) received orally 1 mg/kg of sildenafil suspension 60 minutes before ischemia. Treatment with saline 0.9% in the control group (n=12). Half of the rats was assessed after 24 hours and half after seven days I/R, with new renal scintigraphy to study differential function. After euthanasia, kidneys were removed and subjected to histopathological examination. For statistical evaluation, Student t and Mann-Whitney tests were used. Results: In the control group rats, the left kidneys had significant functional deficit, seven days after I/R, whose scintigraphic pattern was consistent with acute tubular necrosis, compared with the initial scintigraphy (p<0.05). Sildenafil treatment resulted in better differential function of the left kidneys 24h after reperfusion, compared with controls. Histopathologically, the left kidney of control rats (24 hours after I/R) showed a higher degree of cellular necrosis when compared with the sildenafil treated rats (p<0.05). Conclusion: Sildenafil had a protective effect in rat kidneys subjected to normothermic I/R, demonstrated by scintigraphy and histomorphometry

Atualmente, as investigações acerca da personalidade e dos sintomas psicopatológicos, nos estudantes de Psicologia, parecem ser escassas. De modo a que nos pareceu interessante perceber um pouco mais sobre estas personalidades e sobre os sintomas psicopatológicos adjacentes aos mesmos. Assim sendo, o presente estudo teve como objetivo definir o perfil dos estudantes de Psicologia, explorando as variáveis: personalidade, sintomas psicopatológicos e a relação destas com as variáveis sociodemográficas sexo e anos de curso. Para que este estudo se pudesse realizar, foram inquiridos 240 estudantes, do primeiro e segundo ciclo de Psicologia, pertencentes a Instituições de Ensino Públicas e Privadas do Centro e Norte do País. O questionário foi enviado pelas escolas, sob a forma de hiperligação e foi composto pelo Inventário dos Cinco Fatores de Personalidade (NEO-FFI), pelo Inventário dos Sintomas Psicopatológicos (BSI) e pelo Questionário Sociodemográfico, formulado pelo investigador. No NEO-FFI, verificámos que a Conscienciosidade é a dimensão da personalidade mais predominante. E no BSI, averiguámos que a Depressão e o Psicoticismo foram os sintomas psicopatológicos que apresentaram valores médios mais elevados. Na comparação entre sexos pudemos observar que existem diferenças significativas na dimensão da personalidade Abertura à Experiência (NEO-FFI) e na Sensibilidade Interpessoal e Ideação Paranóide (BSI). Em ambos os instrumentos, pudemos observar, também, que o sexo masculino tende a apresentar valores mais elevados em comparação ao sexo feminino. Em suma, neste projeto de investigação encontrámos alguns resultados similares a estudos anteriores e, também, alguns dados que nos despertam a curiosidade e suscitam interesse para futuras investigações. / Nowadays, investigations about personality and psychopathological symptoms on Psychology students seem to be scarce. Because of that it seemed interesting to us to learn more about these personalities and about the psychopathological symptoms behind them. For that reason, the main purpose of the present study was to explore the profile of psychology students in what concerns personality, psychopathological symptoms and their relation with gender and years of graduation. We inquired 240 students, studying in public and private institutions from the centre and north of Portugal, and used three instruments: the NEO Five-Factor Inventory (NEO-FFI), The Brief Symptoms Inventory (BSI) and a Social-Demographic Questionnaire created by the investigator. The results showed that in the NEO-FFI, Conscientiousness was the most predominant dimension. Regarding the BSI, we found that Depression and Psychoticism were the symptoms that presented higher values. In what concerns gender, there was significant differences in the dimension Openness to Experience (NEO-FFI) and in Interpersonal Sensitivity and Paranoid Ideation (BSI). In both instruments there was a tendency to male students score higher than female students. In conclusion, we found some results that are similar to previous studies and also found some indicators that raise curiosity for further investigation on the profile of psychology students.

McLean builds strong connections between the cultural capital of the Jerwood prizewinning craft maker and the world of business and trade. It is crucial that higher education research can consider its relationship to the creative industries. London is a fashion capital, known for its style experimentation and playful creativity. The wit and anarchic play of the art school is a leading force in fashion innovation and Mclean's work articulates this clearly. Designing hats that reference the stylised coiffures of Hollywood icons, in the soft medium of felted wool, is a sophisticated play on the relations between nature and culture that, according to Levi Straus, are at the heart of all culture. The Fifty Hats that Changed the World makes direct allusion to the way that fashion is often regarded with mild disdain as insignificant or trivial, and the Design Museum London, an international leader in disseminating design discourse has, recently, included fashion design within its agenda for exhibition. McLean's work is a leading component of this transformation of design culture.

Cremona developed a reduction theory for binary forms of degree 3 and 4 with integer coefficients, the motivation in the case of quartics being to improve 2-descent algorithms for elliptic curves over Q. In this paper we extend some of these results to forms of higher degree. One application of this is to the study of hyperelliptic curves.

The anticipated growth of air traffic worldwide requires enhanced Air Traffic Management (ATM) technologies and procedures to increase the system capacity, efficiency, and resilience, while reducing environmental impact and maintaining operational safety. To deal with these challenges, new automation and information exchange capabilities are being developed through different modernisation initiatives toward a new global operational concept called Trajectory Based Operations (TBO), in which aircraft trajectory information becomes the cornerstone of advanced ATM applications. This transformation will lead to higher levels of system complexity requiring enhanced Decision Support Tools (DST) to aid humans in the decision making processes. These will rely on accurate predicted aircraft trajectories, provided by advanced Trajectory Predictors (TP). The trajectory prediction process is subject to stochastic effects that introduce uncertainty into the predictions. Regardless of the assumptions that define the aircraft motion model underpinning the TP, deviations between predicted and actual trajectories are unavoidable. This thesis proposes an innovative method to characterise the uncertainty associated with a trajectory prediction based on the mathematical theory of Polynomial Chaos Expansions (PCE). Assuming univariate PCEs of the trajectory prediction inputs, the method describes how to generate multivariate PCEs of the prediction outputs that quantify their associated uncertainty. Arbitrary PCE (aPCE) was chosen because it allows a higher degree of flexibility to model input uncertainty. The obtained polynomial description can be used in subsequent prediction sensitivity analyses thanks to the relationship between polynomial coefficients and Sobol indices. The Sobol indices enable ranking the input parameters according to their influence on trajectory prediction uncertainty. The applicability of the aPCE-based uncertainty quantification detailed herein is analysed through a study case. This study case represents a typical aircraft trajectory prediction problem in ATM, in which uncertain parameters regarding aircraft performance, aircraft intent description, weather forecast, and initial conditions are considered simultaneously. Numerical results are compared to those obtained from a Monte Carlo simulation, demonstrating the advantages of the proposed method. The thesis includes two examples of DSTs (Demand and Capacity Balancing tool, and Arrival Manager) to illustrate the potential benefits of exploiting the proposed uncertainty quantification method.

This paper deploys an orthodox Marxian reading of the concept of subsumption of labour under capital. It does so through a brief, critical overview of the components of the Marxian conceptual instrument of subsumption of labour under capital (formal, real, hybrid and ideal subsumption). Recapitulating Marx’s concept, it sheds some light on the consequences of such a reading as a way of understanding the current transformation of the global higher education sector into a capitalist production sector per se. The reconstruction is then considered here as an attempt to approximate the specifics of the subsumption of labour under capital within the higher education sector. Moreover, the paper aims at showing that a discussion of the university dominated by capital with reference to the functioning or constituting of markets does not provide real opportunities for the understanding and solution of such problems as precarization, exploitation or acceleration of academic work. Thus, it joins a wider stream of Marxist higher education research and could be seen as a conceptual contribution to a critique of the political economy of higher education.

The performance, energy efficiency and cost improvements due to traditional technology scaling have begun to slow down and present diminishing returns. Underlying reasons for this trend include fundamental physical limits of transistor scaling, the growing significance of quantum effects as transistors shrink, and a growing mismatch between transistors and interconnects regarding size, speed and power. Continued Moore's Law scaling will not come from technology scaling alone, and must involve improvements to design tools and development of new disruptive technologies such as 3D integration. 3D integration presents potential improvements to interconnect power and delay by translating the routing problem into a third dimension, and facilitates transistor density scaling independent of technology node. Furthermore, 3D IC technology opens up a new architectural design space of heterogeneously-integrated high-bandwidth CPUs. Vertical integration promises to provide the CPU architectures of the future by integrating high performance processors with on-chip high-bandwidth memory systems and highly connected network-on-chip structures. Such techniques can overcome the well-known CPU performance bottlenecks referred to as memory and communication wall. However the promising improvements to performance and energy efficiency offered by 3D CPUs does not come without cost, both in the financial investments to develop the technology, and the increased complexity of design. Two main limitations to 3D IC technology have been heat removal and TSV reliability. Transistor stacking creates increases in power density, current density and thermal resistance in air cooled packages. Furthermore the technology introduces vertical through silicon vias (TSVs) that create new points of failure in the chip and require development of new BEOL technologies. Although these issues can be controlled to some extent using thermal-reliability aware physical and architectural 3D design techniques, high performance embedded cooling schemes, such as micro-fluidic (MF) cooling, are fundamentally necessary to unlock the true potential of 3D ICs. A new paradigm is being put forth which integrates the computational, electrical, physical, thermal and reliability views of a system. The unification of these diverse aspects of integrated circuits is called Co-Design. Independent design and optimization of each aspect leads to sub-optimal designs due to a lack of understanding of cross-domain interactions and their impacts on the feasibility region of the architectural design space. Co-Design enables optimization across layers with a multi-domain view and thus unlocks new high-performance and energy efficient configurations. Although the co-design paradigm is becoming increasingly necessary in all fields of IC design, it is even more critical in 3D ICs where, as we show, the inter-layer coupling and higher degree of connectivity between components exacerbates the interdependence between architectural parameters, physical design parameters and the multitude of metrics of interest to the designer (i.e. power, performance, temperature and reliability). In this dissertation we present a framework for multi-domain co-simulation and co-optimization of 3D CPU architectures with both air and MF cooling solutions. Finally we propose an approach for design space exploration and modeling within the new Co-Design paradigm, and discuss the possible avenues for improvement of this work in the future.
