This work deals with the numerical-optimisation methods employed for assessing the minimum-lap-time of race vehicles. A particular emphasis is given to the simulations based on the solution of an optimal-control problem.
First, a detailed review is devoted to the optimal-control theory, including direct and indirect methods, together with explicit and implicit formulations.
Three vehicle models are proposed for the implementation in steady-state and dynamic simulations. A steady-state double-track race-car model is presented first, implementing aerodynamic forces, Pacejka-based tyre model, fixed brake-ratio and steady-state lateral-load transfer. This model is then extended including the transient effects for the implementation in a dynamic minimum-time simulation. An essential but comprehensive steady-state motorcycle model is also presented, retaining the peculiar aspects of the motorcycle dynamics, such as the wheelie and stoppie conditions, while assuming the optimal braking-bias.
Then, an optimisation program is developed for computing the race car g-g envelope. A different approach is shown for the steady-state motorcycle model, which is employed for computing the g-g diagrams analytically.
Finally, the most widespread minimum-lap-time simulations are discussed and developed for the presented models, including a quasi-steady-state fixed-trajectory apex-finding approach and a quasi-steady-state fixed-trajectory optimal-control simulation. In addition, a novel approach that combines a steady-state vehicle model with the trajectory optimisation is presented and compared to the discussed simulations. This approach builds upon the formulation of an optimal-control problem and employs the g-g diagrams for limiting the vehicle performance. The results are employed for a sensitivity analysis, that underlines the effect of different parameters on the resulting race line. A dynamic race car model is also implemented in a free-trajectory optimal-control simulation. This program is employed for analysing the effect of different steering geometries on the vehicle performance in different test manoeuvres and during a track lap.

Aquesta tesi doctoral titulada "L'efecte de la raça i trabeculoplastia làser selectiva sobre la dinàmica de l’ humor aquós en pacients amb glaucoma" és el resultat de dos estudis prospectius.
El primer estudi compara la dinàmica de l’humor aquós basal entre 32 pacients blanc-caucàsics i 37 pacients d’origen africà amb hipertensió ocular o glaucoma primari d'angle obert. La pressió intraocular (PIO) es va mesurar mitjançant un pneumotonòmetre; la producció d’ humor aquós es va mesurar mitjançant la fluorofotometria i la facilitat de sortida de l’humor aquós a través de la malla trabecular per tonografia electrònica de Schiøtz. El flux de sortida uveoscleral es calculà utilitzant l'equació de Goldmann assumint una pressió venosa episcleral de 8, 9, 10 i 11 mmHg. Es van analitzar les diferències entre grups amb proves paramètriques i no paramètriques, i la relació entre paràmetres de la dinàmica de l’humor aquós amb una anàlisi de regressió lineal. No es van trobar diferències en la dinàmica de l’ humor aquós entre els pacients blancs i els pacients d’origen africà. No obstant això, els pacients negres tenien còrnies significativament més primes que podrien haver emmascarat diferències potencials en la sortida trabecular de l’ humor aquós i la PIO entre els diferents grups.
Un grup d'aquests pacients van ser tractats amb trabeculoplastia laser selective (SLT) per reduir la seva PIO. El segon estudi va investigar l'efecte de la SLT sobre la dinàmica de l’ humor aquós en 18 ulls. Es va observer una reducció del 21% en la PIO amb un augment del 55% en la facilitat de sortida trabecular 3 mesos després del tractament amb làser. No es van trobar diferències en la producció de l’humor aquós. Així doncs, els resultats van demostrar que la SLT redueix la PIO augmentant la sortida de l’humor aquós a través de la malla trabecular.This PhD titled “The effect of race and selective laser trabeculoplasty on the aqueous humor dynamics in patients with glaucoma” is the result of two prospective studies. The first study compared the baseline aqueous humor dynamics between 32 white-Caucasian and 37 African descent subjects with treatment-naïve ocular hypertension (OHT) or primary open angle glaucoma (POAG). Intraocular pressure (IOP) was measured using a pneumatonometer; morning aqueous humor flow rate was measured by fluorophotometry and trabecular outflow facility by electronic Schiøtz tonography. Uveoscleral outflow was calculated using Goldmann's equation with assumed episcleral venous pressure of 8, 9, 10, and 11 mmHg. Differences among groups were analyzed with parametric and nonparametric tests and the relationship between aqueous dynamics parameters were evaluated with linear regression analyses. No differences in aqueous humor dynamics between black African and white Caucasian patients were found. However, black patients were found to have significantly thinner corneas that could have been masking potential differences in outflow facility and IOP measurements between the racial groups. A group of these patients were treated with selective laser trabeculoplasty (SLT) to reduce their IOP. The second study investigated the effect of SLT on the aqueous humor dynamics in 18 eyes. A 21% reduction in IOP with a 55% increase in trabecular outflow facility was observed 3 months after laser treatment. No differences in aqueous humor production were found. Thus, our results showed that SLT reduces the IOP by increasing the trabecular outflow facility.

Анотація:
This intersectional study explored how mothers of mixed race children negotiate racialised and classed bordering practice in two neighbourhoods within a provincial city in the UK. The research was influenced by Critical Race Theory. It employed a critical interpretation of Bourdieusian symbolic capital to look at how localised spatial dynamics impact on the social geographies of mothers . of mixed race children. Grounded in ethnographic principles, the study explored spatial practice within the two localities as research participants produced a visual representation of the places they took their children in the neighbourhood. Some families participated in a 'go-along', a type of participant observation, in which they were accompanied on a routine trip with their children. This allowed participants to visualise spatial dynamics in real space and time. The study found that classed habitus affects the neighbourhood geographies of families with mixed race children; with those ascribed as middle class having more spatial mobility and ascribed cosmopolitan habitus, than those assigned as lower class. However, working class parents of mixed race children also shared a cosmopolitan habitus and them, and their children, whilst having much less mobility, had more ethnically diverse friendship groups than middle class participants. The study concluded that families with mixed race children make choices about household residence based on an assessment of the social geographies of different localities. Whilst they remain interested in the level and composition of minority ethnic diversity, they are influenced by the intersection of a range of other social differences such as socio-economic differences, symbolic capital (habitus) and geography. New data emerged about potential working class 'edge areas'. These neighbourhoods where families with mixed race children had settled had average numbers of ethnic minority population and residents ascribed as more 'tolerant' towards those racially different, than in other working class urban areas.

Thesis advisor: Janet E. HelmsPart-White Multiracial adults undergo a unique racial identity development process within a racially stratified society. Theorists suggest that different ways of self-designating either improve or impede healthy psychological outcomes for Multiracial people, but virtually no theoretical rationale or empirical studies account for the internal mechanisms underlying self-designations and mental health outcomes. People of Color and White racial identity theories were used to investigate racial dynamics implicit in the identity development and self-designations of Multiracial individuals. The current study examined the relationships between racial self-designations, internalized racial identity, and well-being in part-White Multiracial adults. Part-White (Asian/White or Black/White) Multiracial adults (N = 169) completed a measure of frequency of use of five multiracial self-designations, People of Color and White Racial Identity Attitudes Scales to assess their internal race-related processes (i.e., statuses), and the Brief Symptom Inventory 18 (Derogatis, 2001) and the Rosenberg Self-Esteem Scale (Rosenberg, 1979) to assess healthy and unhealthy psychological outcomes. Multivariate Multiple Regression Analyses were conducted to examine the relationships among racial self-designation and well-being, racial self-designation and internalized racial identity, and internalized racial identity and well-being. Results specific to racial self-designations were (a) greater disorientation about racial dynamics predicted more frequent identification as White and Multiracial, (b) withdrawal from Whiteness increased monoracial minority self-designation and decreased self-designation as Multiracial (c) more complex appraisals of Whiteness predicted more frequent use of most self-designation choices, and (d) an intellectualized view of Whiteness reduced use of the monoracial minority designations and increased identifying with no racial groups at all. Self-designation use was not related to psychological outcomes, but racial identity statuses were. Overall, the results of the study supported examining racial self-designation, internalized racial identity and well-being in a single study. As expected, internalized racial identity was predictive of self-designations and well-being. This study provides initial support for adding conceptual and empirical complexity to discussions about the mental health and wellbeing of Multiracial people. Methodological limitations and implications for future theory, research, and practice are discussed

Анотація:
Virtual prototyping is becoming more and more important and reliable in the automotive field as new tools and software are being developed. This has created the need of virtual drivers and controllers to test virtual vehicles.
In this thesis, we propose a maneuver regulation controller able to steer a vehicle to a desired trajectory. In order to design the controller and subsequently validate it, we study at first two vehicle models, a single track and a double track. Transverse coordinates are then introduced to perform the maneuver regulation in a geometric domain.
The equilibrium states and the behaviour of the proposed models is then explored with an iterative algorithm. This knowledge is used by the controller to perform the dynamic inversion of the system.
The controller is then developed and tested in Python, and its performances are commented.

U.S. higher education is an example of a large multi-organizational system within the service sector. Its performance regarding workforce development can be analyzed through the lens of industrial and systems engineering. In this three-essay dissertation, we seek the answer to the following question: How can the U.S. higher education system achieve an equal representation of female and minority members in its student and faculty populations? In essay 1, we model the education pipeline with a focus on the system's gender composition from k-12 to graduate school. We use a system dynamics approach to present a systems view of the mechanisms that affect the dynamics of higher education, replicate historical enrollment data, and forecast future trends of higher education's gender composition. Our results indicate that, in the next two decades, women will be the majority of advanced degree holders. In essay 2, we look at the support mechanisms for new-parent, tenure-track faculty in universities with a specific focus on tenure-clock extension policies. We construct a unique data set to answer questions around the effectiveness of removing the stigma connected with automatic tenure-clock policies. Our results show that such policies are successful in removing the stigma and that, overall, faculty members that have newborns and are employed by universities that adopt auto-TCE policies stay one year longer in their positions than other faculty members. In addition, although faculty employed at universities that adopt such policies are generally more satisfied with their jobs, there is no statistically significant effect of auto TCE policies on the chances of obtaining tenure. In essay 3, we focus on the effectiveness of training underrepresented minorities (e.g., African Americans and Hispanics) in U.S. higher education institutions using a Data Envelopment Analysis approach. Our results indicate that graduation rates, average GPAs, and post-graduate salaries of minority students are higher in selective universities and those located in more diverse towns/cities. Furthermore, the graduation rate of minority students in private universities and those with affirmative action programs is higher than in other institutions. Overall, this dissertation provides new insights into improving diversity within the science workforce at different organizational levels by using industrial and systems engineering and management sciences methods.Ph.

Turkel, Bryan 9842267. "The Influence of Power Dynamics On the Israeli-Palestinian Ethos of Conflict." Scholarship @ Claremont, 2015. http://scholarship.claremont.edu/cmc_theses/1281.
Анотація:
The study of intractable conflicts has risen in recent years particularly with the work of Daniel Bar-Tal’s work on the ethos of conflict. The ethos of conflict is an original psychological concept that captures the collective societal mindset of cultures locked in intractable conflicts and examines the various factors that keep groups in conflict or help them towards peace. The Israeli-Palestinian conflict is arguably the most researched, publicized, and discussed intractable conflict in history. The purpose of this paper is to first examine the foundation of that intractable conflict through the lens of Bar-Tal’s theory and apply it once more how it has changed in the modern day. Particularly, this paper focuses on how the change in power structure in the Israeli-Palestinian conflict has prioritized the different elements of the ethos of conflict differently for both sides. In the beginning of the conflict, both groups held equitable power that caused them to have similar manifestations of the ethos of conflict. Working with the foundation of Bar-Tal’s theory, this paper provides an analysis of how Israel’s rise to power in the conflict influences different prioritizations of the ethos of conflict for both parties.

In this thesis I look at the Arkansas Project and more specifically the racial dynamics within the project and the surrounding communities in Arkansas where SNCC engaged to assist the residents fight for their civil rights. In addition, I analyze how the differences in the urban and rural communities were affected by the racial dynamics of the project's leadership. The Arkansas project was led by William Hansen, a white man, which made him and the project unique from not only other SNCC projects, but other civil rights organizations. This distinction made the strategy that had to be implemented with the project staff internally and also externally in the Arkansas communities different because his race had to be taken into consideration for all purposes. Another aspect that came into play in Arkansas was the fact that some of their activities occurred in urban communities and others occurred in rural communities. These difference in communities affected not only how the local blacks received the SNCC volunteers, but also affected how local whites received the SNCC volunteers. Although the fact that the Arkansas Project had a white field director made it unique and the racial dynamics worthy of scholarly investigation, Bill Hansen's racial identity was far from the only reason that the organization's work in Arkansas is historically significant. This thesis also looks at the important activities in which SNCC engaged and impacted because of their presence in Arkansas. Of those activities, SNCC impacted the creation of several local groups where local citizens helped to fight for their civil rights, in fighting for their civil rights, those groups engaged in sit-ins, protests, and fighting legal battles in court where some of their cases made it all the way to the United States Supreme Court and impacted the civil rights movement in the south. Two important legal cases that had ramifications for the civil rights movement beyond the state that originated in Arkansas. The cases of Lupper v. State of Arkansas and Raney v. Board of Education made it all the way to the United States Supreme Court out of Arkansas. They helped shape the civil rights movement because Lupper helped clarify sit-in cases and the constitutionality of the arrests. The arrests were deemed unconstitutional because the Civil Rights Act of 1964 forbade discrimination in places of public accommodation and allowed peaceful attempts to be served like any other member of the public from punishable activities in spite of the fact the activities occurred prior to the date of its enactment. In addition, Raney helped define desegregation efforts in the south as many states attempted to avoid the Brown v. Board of Education decision by implementing "freedom of choice plans." Freedom of choice plans were state attempts to circumvent the Brown decision by making the students and their family choose which school they would attend. These cases helped shape the civil rights movement and dealt with sit ins and integrating schools. This thesis provides an important addition to the scholarship about SNCC and SNCC's Arkansas Project.

The main purpose of this thesis is to develop a software to optimize the 3D air race trajectory. Air race competitions such as Red Bull are becoming very popular around the world, but behind this eye catching competitions there are always engineers supporting every team to help their pilots to make the fastest lap time in order to win the competition.
Nowadays, by the help of advanced computing systems and proficient optimization algorithm, engineers are able to model the trajectory of these air races and optimize them offline. These optimized trajectories are handed to the pilots before the competition, in order to help them train themselves in a simulator and then with a real aircraft.
In this thesis the equations of motion (EOM) of point-mass model is used for optimization. The first approach was with the EOM based on Euler angles. As we know from flight dynamics, with the Euler angles we will have a singularity in our equations when the aircraft is experiencing the ±π/2 pitch angle. In order to avoid the singularity in the Euler case, we switch to EOM based on Quaternions. Although the quaternions are used for the optimization of the trajectory, we will also represent the results for Euler based EOM.
The software used to develop the code for this optimization is MATLAB 2016b. Algorithm is proposed and implemented by the author. Build-in optimization function (FMINCON) is used to optimize the trajectory based on the proposed algorithm.

The dynamics of a plant-pathogen interaction vary both within and among species. Both spatial structuring and specific genetic and life-history characteristics will affect the interaction and the outcome of a potential co-evolution between the two organisms. In this thesis I have studied the interaction between the wild perennial herb Silene dioica and its automictic, obligate anther smut Microbotryum violaceum MvSd. From the plant perspective, I have examined different aspects of biochemical resistance in S. dioica to M. violaceum MvSd. From the pathogen perspective, I have focused on the breeding system of M. violaceum MvSd and its connection to fitness and distribution of genetic diversity. I have used varying methods; glasshouse trails involving inoculation of plants with the pathogen, classical Mendelian analysis involving controlled crosses between plants, microscopic studies of spores and molecular DNA-analysis. With the results I demonstrate that resistance to M. violaceum MvSd in S. dioica can be specific to the attacking pathogen strain and also spatially highly diverse both within and among populations within a metapopulation. Together, these factors are likely to delay the establishment of the disease within host populations and reduce the spread and amount of disease, once it has been established. The results also suggest that the specific resistance expressed against two different M. violaceum MvSd strains were determined by separate gene systems and that, in both cases, the resistance was simply inherited. This implies a potential for relatively rapid response to M. violaceum-induced selection in S. dioica populations variable for resistance. My results also show that automixis clearly is the predominating breeding system of M. violaceum MvSd, similarly to what earlier has been shown for M. violaceum MvSl. Furthermore, I found lower levels of neutral genetic diversity in M. violaceum MvSd in the northern parts of Sweden, compared to what has been found in populations in more southern Europe. This result is consistent with predictions that populations in the outer regions of a species distribution have lower levels of genetic variation. Moreover, populations were highly differentiated in northern Sweden, which could have been generated by high selfing rates, genetic drift and high population turnover rates, all factors that coincide with life-history and ecology of M. violaceum MvSd. However, despite the general low variability in neutral genetic markers, I did find variation in fitness related traits, both within and among populations, as well as differences in infection ability between strains, suggesting there is a potential for co-evolution between S. dioica and M. violaceum MvSd in the area. To summarize, this thesis reflect a plant-pathogen system that is highly influenced by constant colonisation-extinction dynamics, which is likely to have influenced both the genetics of resistance in the plant and the breeding system of the pathogen and thus also the interaction between the two organisms.

Анотація:
A numerical study was conducted to determine the effect of changing the camber of a winglet on the efficiency of a wing in two distinct flight conditions. Camber was altered via a simple plain flap deflection in the winglet, which produced a constant camber change over the winglet span. Hinge points were located at 20%, 50% and 80% of the chord and the trailing edge was deflected between -5° and +5°. Analysis was performed using a combination of three-dimensional vortex lattice method and two-dimensional panel method to obtain aerodynamic forces for the entire wing, based on different winglet camber configurations. This method was validated against high-fidelity steady Reynolds Averaged Navier-Stokes simulations to determine the accuracy of these methods. It was determined that any winglet flap deflections increased induced drag and parasitic drag, thus decreasing efficiency for steady level flight conditions. Positive winglet flap deflection at higher lift conditions may increase efficiency, but the validity of the vortex lattice method results for these conditions are dubious. A high-fidelity method should be used for the high lift condition to obtain accurate efficiency data.

Este trabalho apresenta o estudo da dinâmica vertical de um veículo off-road de competição e do comportamento elastocinemático de suas suspensões primárias de duplo estágio com o auxílio da ferramenta computacional de simulação de sistemas multicorpos MSC-ADAMS. O modelo multicorpos do veículo inclui os modelos da suspensão dianteira, suspensão traseira, sistema de direção, pneus e massa suspensa. As análises elastocinemáticas das suspensões definiram geometrias que permitem longos cursos de trabalho das suspensões sem variações indesejadas de parâmetros de projeto. Com a análise modal do modelo de veículo completo foram definidos os valores de rigidez das molas das suspensões de duplo estágio que resultaram em valores de freqüência natural no primeiro estágio semelhantes aos indicados para carros de passeio e no segundo estágio, próximos dos encontrados em veículos de competição. A análise de conforto do veículo durante simulação de passagem por trecho de pista demonstrou que os elementos de força definidos na análise modal resultam em níveis de conforto raramente encontrados em veículos de competição.This dissertation presents the study of a off-road competition vehicle ride and the double rate suspensions elastokinematic behavior using the multibody software MSC-ADAMS. The vehicle multibody model includes the rear and front suspensions, the steering system, the tires and the sprung mass. The suspensions elastokinematic analysis defined geometric configurations that allowed long jounce and rebound travel of wheel, without undesirable project parameters variations. In the modal analysis of the vehicle multibody model, the springs rates that results in natural frequencies values similar to passenger cars for the first suspension stage and, for the second stage, similar to competition vehicles, were defined. The ride analysis during the simulation of the vehicle running on a rough track showed that the force elements defined on the modal analysis resulted in a good ride quality, rarely found in competition vehicles.

Анотація:
Theoretical models of the exchange rate are developed where information on the model is not fully available to agents. It is an application of Benjamin Friedman's (1979) theme that full rational expectations may be a possibility only in the long-run, even for completely rational individuals. The thesis attempts to develop the theory of exchange rate behaviour by considering some neglected informational issues. The three substantive chapters each consider specific aspects of relevance to the determination of the exchange rate from an asset market view of perfect capital mobility. These are the possible current account inter-relationship, the persistence of interest rate differentials between the two currencies and the subjectivity of and the regress in beliefs across a decentralised market. Generally, limited information on the model will give rise to erroneous beliefs, on the one hand, and encourage the acquistion of information and the revision of beliefs, on the other. Erroneous beliefs will cause correlations between variables, which may not normally occur inside full rational expectations. The revision of beliefs will bring a particular source of non-stationarity to the data. And the stability of certain learning forms may require limitations on the degree of capital mobility. These conclusions would suggest that any empirical work on modelling the exchange rate may gain from relaxing certain a priori restrictions, which properly belong to models with stronger assumptions on the availability of information.

We estimate a multivariate unobserved components stochastic volatility model to explain the dynamics of a panel of six exchange rates against the US Dollar. The empirical model is based on the assumption that both countries' monetary policy strategies may be well described by Taylor rules with a time-varying inflation target, a time-varying natural rate of unemployment, and interest rate smoothing. The estimates closely track major movements along with important time series properties of real and nominal exchange rates across all currencies considered. The model generally outperforms a benchmark model that does not account for changes in trend inflation and trend unemployment. (authors' abstract)Series: Department of Economics Working Paper Series

Ce travail de thèse se concentre sur l'analyse des facteurs interindividuels de la performance et de leurs liens avec les facteurs environnementaux dans la discipline du triathlon, en particulier sur les formats de triathlon présents aux Jeux Olympiques. Les performances dans les courses de triathlon, où les triathlètes interagissent les uns avec les autres, comme c'est le cas sur les parcours de triathlon de courte distance (super-sprint, sprint et standard), dépendent de l'utilisation optimale des capacités individuelles ainsi que de l'adaptation de l'effort à la dynamique de la course. La discipline du triathlon courte distance a évolué sur le plan réglementaire et technologique au cours des vingt dernières années. Par conséquent, l'objectif de cette recherche était de comprendre les dynamiques de course sur ces formats courts en fonction des profils de triathlètes présents, et de quantifier les niveaux de performance de chacun en tenant compte de la concurrence, qui est le paramètre le plus similaire entre chaque course. Les premières études (1 et 2) se sont penchées sur le format novateur du relais mixte, qui a été introduit aux Jeux Olympiques de Tokyo 2020. Ce format ultra-court propose une dynamique de course axée sur la préservation de la position et implique une proximité élevée entre les athlètes. Nous avons ainsi observé les stratégies mises en place par les équipes et identifié les profils de triathlètes correspondant à chaque relais. Dans un second temps, nos recherches se sont orientées vers le format standard (études 3 et 4), également présent aux Jeux Olympiques et obligatoirement concouru par les athlètes du relais. Dans ces études, nous avons cherché à estimer le niveau de chaque athlète en utilisant un système d'échange de points en fonction des probabilités de victoire et de défaite entre chaque paire d'athlètes. Ce système nous a permis d'évaluer la densité de la concurrence lors d'une course et la performance cible d'un athlète. De plus, en le reliant à la typologie des parcours, nous avons pu observer les dynamiques de groupe en course et estimer la probabilité de réussite d'une échappée à l'issue de la natation et de la partie cyclisteThis thesis work revolves around the analysis of inter-individual factors affecting performance and their connection with environmental factors within the context of triathlon, particularly focusing on the triathlon formats featured in the Olympic Games. Performances in triathlon races, where triathletes interact with each other, as seen in the short-distance triathlon formats (super-sprint, sprint, and standard), depend on the optimal utilization of individual capacities and the adaptation of effort to the race dynamics. The discipline of short-distance triathlon has evolved both in terms of regulations and technology over the past two decades. Therefore, the research objective was to understand race dynamics in these short formats based on the profiles of the participating triathletes and to quantify the performance levels of each athlete while taking into account the competition, which is the most consistent parameter across different races. The initial studies (1 and 2) focused on the innovative format of mixed relays introduced in the 2020 Tokyo Olympics. This ultra-short format involves race dynamics centered around maintaining position and high proximity among athletes. We observed the strategies adopted by teams and identified the profiles of triathletes corresponding to each relay.Subsequently, our research shifted towards the standard format (studies 3 and 4), also featured in the Olympics and compulsory for relay athletes. In these studies, we aimed to estimate the level of each athlete using points exchange system based on the probabilities of victory and defeat between each pair of athletes. This system allowed us to assess the density of competition in a race and the target performance of an athlete. Furthermore, by connecting it to course typology, we were able to observe race group dynamics and estimate the probability of a successful breakaway after the swimming and cycling segments

High inflation economies have ultimately been successful in stabilising their prices using the exchange rate as a nominal anchor. Besides stabilization, these recent examples have shown boom-recession cycles, contrary to what can be expected from (pure) money-based stabilizations. Various theoretical explanations of such boom-cycles are discussed and a model of aggregate supply and demand generating such an outcome is developed. There the boom dynamics depend mainly on a slump in real interest rates and wage flexibility. (author's abstract)Series: Department of Economics Working Paper Series

This thesis examines the nature of sexual violence, the trauma experienced by survivors, how report rate for this type of crime can be increased, and how secondary victimisation of survivors can be prevented. Laboratory examination of the attributions made about survivors of sexual violence found that they not only differ from those made about survivors of non-sexual crimes, but also that negative attitudes are strongly related to the gender-role attitudes of the attributor. Empirical research also suggested that providing written information may not be sufficient to alter negative attitudes. Results of a general public crime survey (N=266) suggest that the trauma experienced by survivors of sexual violence is higher than that of survivors of other crime types. Specific examination of the experiences and recovery of survivors of sexual violence (N=42) found that severe assaults, recent victimisation, and assault by a known offender, are related to high levels of symptomatology. Negative self-attributions and perceptions were also found to be related to high levels of symptomatology, and these cognitions were found to be the strongest predictors of recovery. Unlike previous findings with other subject groups, self-blame was not found to be related to increased control. Examination of post-assault factors suggests that the low report rate for sexual crimes may be due to lack of faith in the police and fear of Criminal Justice interactions. In addition, it was found that dissatisfaction with report decision was highly related to levels of symptomatology. A model of how assault factors, survivor cognitions and post-assault interactions may relate to each other and symptomatology is presented. The findings of the survey and laboratory research are discussed in terms of their implications for successful support of survivors, increasing report rate for sexual crimes, the prevention of secondary victimisation, and future psychological research.

Spontaneous brain activity, measured under the absence of any overt task, has been investigated under the label of “resting state” for about 20 years with rising interest. While it was known since the beginnings of modern electrophysiology that the brain exhibits spontaneous fluctuations also during rest, the discovery, in 1995, that these fluctuations possess a robust spatio-temporal structure had a profound impact on how we understand and investigate brain activity. In this dissertation, we characterize the spatio-temporal dynamics of resting state on a macroscopic level using fMRI recordings from humans and combining novel data analysis tools with theoretical models on the level of the whole brain. We demonstrate the presence of common patterns of functional connectivity, known as resting state networks (RSNs), that evolve in time in both empirical and model data. We show that spontaneous fluctuations and their statistics are determined by the structure of the brain network and its dynamics.La actividad cerebral espontánea, o actividad de reposo, es aquella que uno puede registrar cuando el cerebro no está involucrado en ninguna tarea impuesta del exterior (tal como sería la presentación de un estímulo). El estudio de la actividad de reposo ha conocido un interés creciente durante los últimos 20 años. Si bien las fluctuaciones en la actividad de reposo eran conocidas desde los inicios de la electrofisiología moderna, el descubrimiento, en 1995, de que estas fluctuaciones muestran patrones espaciotemporales robustos ha tenido un impacto profundo en la manera de entender e investigar la actividad del cerebro. En esta disertación caracterizamos la dinámica espaciotemporal de la actividad de reposo a nivel macroscópico usando registros de fMRI en humanos y combinando nuevas herramientas de análisis y modelos teóricos del cerebro a gran escala. Observamos patrones comunes de conectividad funcional evolviendo en el tiempo tanto en los datos empíricos como en las simulaciones. Demostramos que las fluctuaciones de reposo y su estadística son determinadas por la estructura de la red cerebral y su dinámica.

This thesis provides evidence in favour of the long-run validity of Purchasing Power Parity (PPP) using primarily a linear error correction framework. Through an examination of PPP where proportionality and symmetry are implicitly imposed, it is shown that a selection of twelve EU real exchange rates is stationary on a univariate basis. The contribution here is based on the reconciliation of unit root test outcomes across univariate and panel tests. Following this analysis, the Johansen cointegration procedure is employed to examine whether long-run equilibrium relationships can be identified in systems of real exchange rates. The implications of results found are set out in terms of regional exchange rate policy co-ordination, exchange rate regime appropriateness, and monetary integration. By focussing on interdependent regions that were affected by a major financial shock (Europe: EMS crisis; Latin America: Mexican crisis; South East Asia: 1997 crisis), the real exchange rate dynamics are compared in pre- and post-crisis scenarios.This thesis also presents evidence in favour of PPP by examining the less restrictive scenario where neither proportionality nor symmetry is imposed. Given the fact that most developed economies have highly integrated goods and capital markets and liberalised capital accounts, the failure to find evidence for PPP in previous studies may be due to the exclusion of factors that might reflect the behaviour of capital markets and their influence on the exchange rate. To test this, the traditional nominal exchange rate and domestic/foreign price based system is augmented with an interest rate component. In a tripolar specification, the joint test of PPP and Uncovered Interest Parity (UIP) is found to hold in a system comprising Germany, Denmark and the UK, suggesting well-integrated goods and capital markets and the long-run convergence evident suggests that Denmark and the UK might be suitable for membership of the euro area. This convergence appears to be stronger when short-term interest rates are used as opposed to long-term rates (perhaps since they are not subject to distortions such as taxation and maturity levels). Furthermore, long-rates have been associated recently with an inversion of the yield curve, while evidence to support the yield curve in non-crisis times is mixed. Finally, multivariate and panel cointegration procedures are employed to provide evidence for the suitability of potential future euro area entrants from Central and Eastern Europe in tri-variate systems comprising the euro nominal exchange rate and two price series.

The rand has since the mid-1980s maintained a long swing of decline that reversed in 2002 for a brief while; resuming the swing shortly thereafter. In contrast to these fairly predictable fluctuations, the rand’s short run movements are increasingly volatile and seemingly unpredictable. Anchored in the asset approach to exchange rate determination, this study examines the two issues of the long run and short run exchange rate dynamics of the rand.
