description: Advancements in spectroscopy rely on the improvement of two fundamental characteristics: spatial and temporal resolutions. High harmonic spectroscopy (HHS) is an emerging technology that promises the capability of studying the fastest processes that exist today: electronic motion with angstrom spatial and attosecond temporal resolution. HHS is based on the process of high harmonic generation (HHG) which arises from the nonlinear interaction between an intense, infrared laser pulse and an atomic or molecular gaseous medium, producing coherent, attosecond-duration bursts of extreme ultraviolet (XUV) light. In order to utilize the attosecond pulses for spectroscopic measurements, it is necessary to improve the conversion efficiency of HHG. Chapter 2 of this thesis describes the improvements we make to the HHG source in order to obtain high XUV photon flux and we report on the nonlinear ionization of atomic systems using these pulses in Chapter 6. In Chapters 3 - 5, we describe several HHG experiments in complex, polyatomic molecules in order to promote the use of HHS as a general spectroscopic tool. Amplitude modulations in high harmonic spectra of complex molecules can be attributed to several types of interference conditions that depend on a system's molecular or electronic structure such as recombination with multiple centres or dynamical interference from multi-orbital contributions to ionization. Our results demonstrate the capability of HHS to extract useful information on molecular and electronic structure from large, polyatomic molecules directly from their high harmonic spectra. Furthermore, we use HHS to investigate the suppression of ionization in complex molecules due to quantum destructive interference during ionization as well as the distinguishability of emitted harmonic spectra from molecular isomers. Chapter 6 explores the study of multi-electron dynamics in complex molecules using XUV multiphoton ionization of atoms and molecules as well as the ionization and fragmentation of C60 which has hundreds of delocalized valence electrons. This thesis also describes the author's role in the design and fabrication of a time-of- flight mass spectrometer (Section 6.1) as well as an HHG detector system (Appendix A).

description: Abstract The present study investigated whether autobiographical memories serve to maintain feelings of intimacy in times of social isolation that result from the restrictions related to the COVID‐19 pandemic. Data came from 104 young and older adults who reported three important and three social memories, that is, memories about someone the participants were unable to meet because of the pandemic‐related restrictions. Our findings support that social memories more frequently serve intimacy functions than important memories do, and this difference is more pronounced for older compared to young adults. Moreover, social loneliness is associated with less frequent use of important memories for intimacy functions, whereas emotional loneliness shows a positive association. Results are discussed in terms of what type of memories can be used to maintain intimacy feelings across age groups and regarding qualitative and quantitative aspects of loneliness that differently predict the use of memories for intimacy functions.

description: We present a measurement of the pseudorapidity density of primary charged particles near midrapidity in Au+Au collisions at sqrt[SNN]=130 GeV as a function of the number of participating nucleons. The pseudorapidity density, dNch/dη||η|≤1/(1/2〈Npart〉) , rises from 2.87±0.21 in peripheral events (〈Npart〉∼83) to 3.45±0.18 in central events (〈Npart〉∼ 353), which is 53±8% higher than pp̄ collisions at a similar center-of-mass energy. This is consistent with an additional contribution to charged particle production that scales with the number of binary nucleon-nucleon collisions (Ncoll).

Human-Biomonitoring

description: Lead (Pb) is a naturally occurring heavy metal that received, in the last decades, much attention in the human health risk assessment community. In the European Human Biomonitoring Initiative (HBM4EU), Pb was identified as a priority substance as various scientific and policy questions were open and still to be answered. They included the further investigation of the internal exposure to Pb, the factors determining it, and its variations within European populations. The aim of this work was to develop an integrative modeling framework for the assessment of the aggregated long-term exposure to Pb in Belgium, Czech Republic, Germany, and Norway. This framework enabled predicting the concentrations of Pb in human blood (PbB) from estimates of the external exposure. The effect of past and current exposure events was accounted for, as multiple country-specific Pb concentration data in environmental compartments and diet, and estimates of the dietary intake of Pb covering a period from the 1970s until the present times were compiled. This modeling approach allowed, using a twodimensional Monte Carlo (MC2D) approach, running a population-based simulation and characterizing the inter-individual variability within the simulated populations and the uncertainty on the external exposure estimates. The predicted PbB levels were compared with the results drawn from HBM data. To the best of our knowledge, this holistic modeling approach combines for the first time temporal and country-specific trends in environmental lead concentrations to derive internal exposure, in order to get better insights into the relationship between environmental and human lead exposure, and to characterize individual exposure at different ages. © The Author(s)
Design and syntheses of photoactive polymer systems capable of chemical amplification.

Subjects: subject: Chemistry, Organic.

description: A short history of the development of resist systems for use in the electronics industry is given. The shortfalls of classical resist systems are exposed, and the phenomenon of chemical amplification is shown as a possible way of circumventing these shortfalls. A review of polymeric resists showing chemical amplification is given. Polycarbonates bearing photolabile ortho-nitrobenzyl groups are shown to be theoretically capable of undergoing photodepolymerization. Several synthetic approaches to such polymer systems are presented. One of the proposed pathways leads to the desired polymer. This polymer shows the expected photochemically induced depolymerization, however the temperature differential between the depolymerization of the protected and deprotected polymer is insufficiently large to give complete development of an image. A novel approach towards the t-butyloxycarbonylation of alcohols, phenols, thiols, and enols under phase-transfer conditions is presented. This method is also extended to the t-butyloxycarbonylation of polymer bearing pendant hydroxyl groups such as novolac and poly(p-hydroxystyrene). The selective t-butyloxycarbonylation of polyfunctional molecules is also explored. Another approach in the design of photoactive polymer is achieved by the introduction in the main chain or in pendant groups of the t-BOC group, or structures resembling it, that are capable of undergoing acidolysis on irradiation in the presence of a catalytic amount of an onium salt. The introduction of t-BOC bearing pendant groups is attempted both through polymer modification of PVCLO and monomer synthesis starting from vinyl chloroformate. The synthesis of polymers having t-BOC groups directly attached to the main chain is not achieved, however polymers containing a spacer group between the main chain and the t-BOC group are prepared successfully. These polymers show the expected thermal loss of isobutene and carbon dioxide at 200$\sp\circ$C, however, on irradiation in the presence of an onium salt, acidolysis is incomplete because of the occurence of other cleavages that are not catalytic in nature. The synthesis of polymers having main chains with t-BOC-like structures in their main chain is achieved by the reaction of diimidazolides with various diols. In this way linear polycarbonates are made that contain either tertiary carbonates, or secondary benzylic carbonates in their main chain. These polymers are capable of undergoing catalytic depolymerization on irradiation in the presence of an onium salt and are currently still under study as potential resist systems.

description: Bologna nel Seicento ha una produzione calcografica molto ricca che comprende vari esemplari per insegnare disegno ai principianti. Questa tipologia riscuote un certo successo, e accanto agli esemplari di dettagli anatomici, se ne stampano di elementi decorativi. La prima e più importante prova è quella di Agostino Mitelli, pittore quadraturista di straordinario calibro, che pubblica, a partire dal 1636, due serie di cartuches ed elementi di ornato di sua invenzione. Queste serie sono di particolare interesse per la raffinatezza delle soluzioni proposte, ma anche per la grande fortuna che riscuotono, che porta a varie riedizioni. Vengono infatti ristampate in Francia, grazie all'intervento di Stefano della Bella, con il quale Agostino ha un mutuo e proficuo rapporto di scambio. Stefano della Bella compie infatti un'importante impresa editoriale dando alle stampe varie serie di elementi di ornato in Francia, serie che possiede e studia lo stesso Agostino. La produzione impostata dal grande quadraturista continua a Bologna grazie alle prove di suo figlio Giuseppe Maria e dell'allievo Domenico Santi che propone soluzioni manierate rispetto quelle del maestro.
description: During the 17th century Bologna had a very remarkable chalcographic production that included models which taught beginners to draw. This typology of engraving was extremely successful and not only models of anatomical details, but also decorative elements were printed. The first and most important character of the ornamental production was Agostino Mitelli, who, since 1636, put into print two series of cartouches and ornamental elements of his own invention. These series were of particular interest for the refinement of the proposed solutions and their huge success brought to some reissues. Thanks to Stefano della Bella, who had a mutual and profitable relationship with Agostino, those series were in fact reprinted in France. Furthermore Stefano della Bella made an important publishing venture in France by printing various series of ornamental elements which were owned and studied by Agostino himself.The production formulated by this great fresco painter continued in Bologna thanks to his son Giuseppe Maria Mitelli and his scholar Domenico Santi who proposed mannered solutions compared to those of his own teacher.
title: Toddler Internalizing and Externalizing Problem Behaviors and Child Care Provider Mental Health

description: Caregiver depression, particularly maternal depression, has repeatedly been shown to be a risk factor for the development of problem behaviors in young children. Problem behaviors fit within two categories: internalizing and externalizing. Externalizing behaviors include peer aggression, defiance, and impulsivity. Internalizing behaviors include generalized anxiety, withdrawal, separation distress, depression, and inhibition to novelty.
Gaps still exist in the research regarding the mental health of other caregivers that directly interact with children’s lives. Increasingly more children spend a great deal of time in child care settings. Less is known about child care provider stress and depression in relation to toddler problem behaviors.
Previous investigations found that child care provider education, experience, and interactions with the children influence quality. These variables are also related to toddler problem behaviors. Other factors such as child care provider mental health have yet to be explored fully to understand its influence on the development of problematic behaviors in young children.
This research sought to explore the associations among child care provider stress and depression and toddler internalizing and externalizing problem behaviors. Data from he Utah State University Child Care Access Means Parents In School (CCAMPIS) grant were analyzed. Additional child care providers in Utah were sampled, as well as parents in their program who had toddler aged children.
Results indicated that a high number of toddlers in the sample showed higher levels of negative emotionality and depression symptoms compared to previous research with children in child care. Toddler aged male children showed higher levels of impulsivity. In contrast to previous research, higher family income was associated with higher toddler peer aggression. Additionally, high levels of child care provider stress were correlated with higher levels of peer aggression. This small exploratory research study points to the need for further research to look at these variables and other possible contributing factors.

description: Gantry-tilted helical multi-slice computed tomography (CT) refers to the helical scanning CT system equipped with multi-row detector operating at some gantry tilting angle. Its purpose is to avoid the area which is vulnerable to the X-ray radiation. The local tomography is to reduce the total radiation dose by only scanning the region of interest for image reconstruction. In this paper we consider the scanning scheme, and incorporate the local tomography technique with the gantry-tilted helical multi-slice CT. The image degradation problem caused by gantry tilting is studied, and a new error correction method is proposed to deal with this problem in the local CT. Computer simulation shows that the proposed method can enhance the local imaging performance in terms of image sharpness and artifacts reduction.

description: Rapid immune reconstitution (IR) following stem cell transplantation (SCT) is essential for a favorable outcome. The optimization of graft composition should not only enable a sufficient IR but also improve graft vs. leukemia/tumor effects, overcome infectious complications and, finally, improve patient survival. Especially in haploidentical SCT, the optimization of graft composition is controversial. Therefore, we analyzed the influence of graft manipulation on IR in 40 patients with acute leukemia in remission. We examined the cell recovery post haploidentical SCT in patients receiving a CD34+-selected or CD3/CD19-depleted graft, considering the applied conditioning regimen. We used joint model analysis for overall survival (OS) and analyzed the dynamics of age-adjusted leukocytes; lymphocytes; monocytes; CD3+, CD3+CD4+, and CD3+CD8+ T cells; natural killer (NK) cells; and B cells over the course of time after SCT. Lymphocytes, NK cells, and B cells expanded more rapidly after SCT with CD34+-selected grafts (P = 0.036, P = 0.002, and P < 0.001, respectively). Contrarily, CD3+CD4+ helper T cells recovered delayer in the CD34 selected group (P = 0.026). Furthermore, reduced intensity conditioning facilitated faster immune recovery of lymphocytes and T cells and their subsets (P < 0.001). However, the immune recovery for NK cells and B cells was comparable for patients who received reduced-intensity or full preparative regimens. Dynamics of all cell types had a significant influence on OS, which did not differ between patients receiving CD34+-selected and those receiving CD3/CD19-depleted grafts. In conclusion, cell reconstitution dynamics showed complex diversity with regard to the graft manufacturing procedure and conditioning regimen.

description: Background: Implementing adequate strategies to assess the value of health services plays a central role in the effort to deal with the financial pressures faced by health care systems worldwide. This study aimed to understand which approaches to value assessment have been used in developed countries. Methods: We conducted a rapid review and a gray literature search to identify value assessment frameworks. A two-stage screening process was utilized to identify existing approaches and cluster similar frameworks. In addition, we developed an interpretive classification system to make sense of existing approaches. Results: One thousand one hundred seventy-six references were identified and 38 papers were selected for full-review. Among these 38 articles, 22 distinct approaches to assess value of health care interventions were identified and classified according to four points: 1) use of single or multiple considerations to base value estimates; 2) use of disease-specific or generic criteria; 3) reliance on process-based or outcomes-based consideration; and 4) type of input and evidence considered. Conclusions: The contextual nature of value assessment in health care becomes evident with the diversity of existing approaches. Despite the predominance of cases relying on the Incremental cost-effectiveness ratio as the measure of value, this approach has not been sufficient to meet the needs of decision-makers. The use of multiple criteria has become more and more important, as well as the consideration of patient-reported measures. Considerations of costs are not always explicit and consistent.

description: Paul Flandrin (Lione 1811- Parigi 1902) è un pittore dalla lunga carriera, i cui inizi si snodano tra la formazione presso l’Académie des Beaux Arts di Lione e l’atelier di Ingres a Parigi. Sarà però durante il viaggio in Italia (1834-1838) che il pittore individuerà la sua precisa vocazione di pittore di paesaggio. Il periodo trascorso a Roma, non pensionnaire di Villa Medici ma assiduo frequentatore della Accademia di Francia, all’epoca diretta dal suo maestro, è significativo per individuare le prime prove di un artista che si pone tra l’influenza di Corot e l’insegnamento di Ingres. Per un pittore di educazione neoclassica, quanto conta l’esperienza italiana? Per un allievo di Ingres, cosa significa la scelta del paesaggio? Per un paysagiste che arriva a Roma negli anni Trenta, in cosa consiste l’eredità di Corot? L’articolo tenta di dare risposta a queste domande attraverso l’individuazione di alcune tappe fondamentali della produzione grafica e pittorica di Paul Flandrin compresa negli anni del soggiorno italiano. L’indagine si concentra sulla comprensione del metodo di lavoro dell’artista, dalla percezione della natura vista e studiata dal vero alla ricomposizione in atelier. Dall’analisi emerge la figura complessa di un pittore di formazione neoclassica che opera nel XIX secolo inoltrato.
description: Paul Flandrin (1811-1902) is a painter with a long career, whichbegan at Lyon’s Fine Arts Academy and went on in Paris, both atthe Academy and in Ingres’ atelier. But it was only during his fiveyears trip to Italy (1834-1835) that he found his vocation as alandscape painter. In Rome, even if he was not a pensionnaire ofthe Villa Medici, he became acquainted with the Academy circle,where the master Ingres was the Director. Over the course ofthese five years, Paul Flandrin looked closely at Corot andlearned from Ingres.For a painter with a classical education, how much does theexperience in Italy matter? For a pupil of Ingres, what does thechoice for landscape mean? For a landscape painter arriving inRome in the 1830s, what does Corot’s heritage mean?The article aims to answer these questions through a selection ofpreviously unknown artworks, both drawings and paintings. Theresearch moves from the analysis of the artist’s method, hisperception of nature on the spot, his fast recording and the finalcomposition in the studio. There comes out the complex profile ofa neoclassical landscape painter working in the 19th century.

description: INTRODUCCIÓN Y OBJETIVOS:

El síndrome de deleción 22q11.2, síndrome velo-cardio-facial o de DiGeorge, ocurre aproximadamente en 1:1524-1:4000 nacidos vivos. Además de las afecciones físicas, entre el 20-40% de estos individuos acaban recibiendo el diagnóstico de esquizofrenia.

 

DESCRIPCIÓN DEL CASO:

Mujer de 28 años (CI:62), en seguimiento en psiquiatría desde 2013 por crisis clásticas de llanto y agitación ante pequeños estímulos estresantes o frustrantes.

Acude a urgencias tras varios días de inquietud psicomotriz y alteraciones de conduta en el domicilio resultantes de la presencia de sintomatología delirante.

 

EXPLORACIÓN Y PRUEBAS COMPLEMENTARIAS:

Psicopatológicamente: Consciente, orientada, abordable y colaboradora. Escaso contacto visual. Ánimo hipotímico. Ansiedad ideica y somática grave. Discurso circular centrado en ideación delirante de perjuicio. Vivencias de control, falsos reconocimientos. Resto sin alteraciones.

Las pruebas de imagen (RMN, TC, EEG) y analíticas resultaron anodinas.

 

DIAGNÓSTICO DIFERENCIAL Y TRATAMIENTO:

Dado que la paciente no cumplía los criterios temporales para el diagnóstico de esquizofrenia, se filió el cuadro como trastorno psicótico agudo con predominio de ideas delirantes (F23.3)

Durante el ingreso, se disminuyó la dosis de risperidona a 2mg/día y se pautaron dosis crecientes de clozapina hasta 50mg/día asociando paroxetina 20mg/día, con buena tolerancia, encapsulándose la ideación delirante.

 

DISCUSIÓN Y CONCLUSIONES:

Entre los mecanismos más aceptados en la aparición de sintomatología psicótica en los pacientes con síndrome de DiGeorge se encuentran: la reducción tanto en los tractos de sustancia blanca observados en la corteza cingulada anterior; como en el volumen de corteza entorrinal y la mayor activación del giro parahipocampal, hiperactividad funcional en la corteza auditiva primaria y de forma más importante, la maduración anormal del córtex prefrontal por disfunción dopaminérgica, lo que justifica en parte la excelente respuesta a antipsicóticos bloqueantes dopaminérgicos.

En conclusión, la comprensión de la vulnerabilidad de estos pacientes a presentar sintomatología psicótica es crucial para el desarrollo de intervenciones centradas en su prevención, tratamiento y recuperación funcional.

description: Finite field multiplication is one of the most useful arithmetic operations and has applications in many areas such as signal processing, coding theory and cryptography. However, it is also one of the most time consuming operations in both software and hardware, which makes it pertinent to develop a fast and efficient implementation. We propose four improved FPGA multiplication implementations using the Karatsuba and Fast Fourier Transform algorithms over GF (2n). We also implement the hyperelliptic curve coprocessor and compare the results of our finite field arithmetics on the ring arithmetics. Three of our implementations are based on the Karatsuba algorithm which has a running time of O (n1.585). Our final implementation is based on Fast Fourier Transform algorithm who's running time is O (nlog(n)). They are a significant increase from the classical schoolbook algorithm which has a running time of O (n2). We then approximate the ring arithmetic's performance in our hyperelliptic curve coprocessor by applying our finite field implementations. We had improvements of up to 96 percent over the classical multiplier. We conclude that we have the most efficient ring arithmetic FPGA implementation with regards to area and speed.

Three-dimensional image formation in fiber-optical second-harmonic generation microscopy

description: Three-dimensional (3-D) image formation in fiber-optical second-harmonic-generation microscopy is revealed to be purely coherent and therefore can be described by a 3-D coherent transfer function (CTF) that exhibits the same spatial frequency passband as that of fiber-optical reflection-mode non-fluorescence microscopy. When the numerical aperture of the fiber is much larger than the angle of convergence of the illumination on the fiber aperture, the performance of fiber-optical second-harmonicgeneration microscopy behaves as confocal second-harmonic-generation microscopy. The dependence of axial resolution on fiber coupling parameters shows an improvement of approximately 7%, compared with that in fiber-optical two-photon fluorescence microscopy.
Comparison of methods for calculating internal work of elite running.

description: There are two basic models that are used to calculate the internal work involved in movement. The first, an energy-based model, calculates the changes in the energy of the segments. There are many variations of this model but Aleshinsky (1986) has shown that this approach lacks mathematical validity. The other, a power-based model, integrates the joint powers to find work. A modified power model (using absolute values) was shown by Aleshinsky (1986) to be mathematically valid but has only been used in two studies (Chapman et al., 1987; Caldwell and Forrester, 1992) each having only one subject. A version of this model was used in this study and was termed the absolute power method. For comparison purposes a modified version of the energy approach, called the absolute work method, was used. The internal work was then normalized for body mass and running velocity to obtain the "internal biomechanical cost" (IBC). The IBCs of normal running for four elite male and four elite female runners were compared to their IBCs of four inefficient running styles. The absolute power method was able to detect that the inefficient runs produced significantly higher internal work than normal running in 30 out of 32 cases (94%). Absolute work (the energy approach) could detect the inefficient runs in only 15 out of 32 cases (46%). As well, the absolute work approach was shown to be more variable and less reliable than the absolute power approach. The absolute power method also proved to be a useful tool for examining the work performed at each joint during a movement, thereby providing insight into where significant inefficiencies occur.

description: In the realm of High-Performance Computing (HPC), the parallelization of programs holds significant importance. However, the correctness of parallelization hinges on the reliable exclusion of certain data dependences, such as read-after-write dependences, where a read access follows a write access on a given memory location. It is imperative that data dependence analyses are not only correct but also as precise as possible to seize every opportunity for parallelization.

While various static, dynamic, and hybrid analysis approaches have been proposed within the HPC community, none have been based on program logic and deductive verification, despite the significant advantages this approach offers, including soundness, precision, and modularity.

In this thesis, we present an automatic, sound, and highly precise approach to generate data dependences based on deductive verification. We define a program logic based on precise semantics for data dependences. As loops are usually the main source of parallelization in HPC applications, we equip our approach with an automatic loop invariant generation technique in the same program logic. To achieve full automation, we incorporate predicate abstraction tailored to the needs of data dependence analysis. To retain as much precision as possible, we generalize logic-based symbolic execution to compute abstract data dependence predicates.

We provide a prototype demonstrating that fully automatic data dependence analysis based on deductive verification is feasible and is a promising alternative to the dependence analyses commonly used in HPC. Implementing our approach for Java atop a deductive verification tool, we conducted evaluations demonstrating its ability to analyze data dependences highly precisely for representative code extracted from HPC applications.

description: L’articolo è stato ispirato dall’ultimo lavoro di Lorna Simpson, artista che vive e lavora a Brooklyn. Nei suoi lavori fotografici Simpson affronta il tema dell’identità afroamericana, esplorando e mettendo in discussione le questioni di genere, razza e cultura. Nella sua mostra dal titolo “Gathered” all’Elizabeth A. Sackle Center for Feminist Art presso il Brooklyn Museum di New York nel 2011, Simpson ha realizzato due installazioni di ritratti fotografici di donne di colore. Nella prima installazione Simpson ha esibito una serie di ritratti di sconosciute donne di colore realizzati tramite cabina per fototessere, acquistati su eBay e collezionati dall’artista. La seconda, May June July August 1957/2009 (2009), è costituita da una serie di scatti vintage in bianco e nero di una giovane donna afroamericana, in pose da pin-up: tra essi, l’artista ha inserito i propri ritratti, interpretando le stesse pose della modella sconosciuta. Collegando i ricordi personali ad una ricostruzione immaginaria del passato, le opere in mostra a Brooklyn segnalano una nuova direzione dell’indagine di Simpson sulla memoria, sulla verità e sulla finzione.
description: The article is inspired by the latest work of Lorna Simpson, a Brooklyn-based artist. In her photoworks Simpson deals with the African American identity, exploring and challenging issues of gender, race and culture. In her show entitled “Gathered” and displayed at the Elisabeth A. Sackle Center for Feminist Art in the Brooklyn Museum of New York in 2011, Simpson realizes two installations of black females photographic portraits. In the first installation Simpson exhibit a series of photo-booth portraits of unknown black women, bought on e-Bay and collected by the artist. The second one, May June July August 1957/2009 (2009), is made up by a series of black and white vintage snapshots of a young African American woman, posing for pinups: among them, the artist inserts her own portraits, acting the same poses of the unknown model. Linking personal memories with a fictionalized reconstruction of the past, the work exhibited in Brooklyn points a new direction of Simpson’s investigation on memory, truth and fiction.
Integrating social modelling and agent interaction through goal-oriented analysis

description: In the Agent-oriented software engineering (AOSE) community, it is now widely recognised that interaction is perhaps the most important single characteristic of complex software systems. Recently, the focus of AOSE research has shifted towards social (or organisational) modelling, which allows interaction to be modelled with higher-level constructs like organisational structures and social policies. However, a gap remains between the social models proposed in AOSE methodologies and the increasing number of sophisticated agent interaction frameworks outside AOSE, such as those based on auctions, commitments, and dialogue games. Hence, social models in AOSE methodologies need to have more 'hooks' to enable integration with rich domain-specific agent interaction frameworks. Towards closer integration between social modelling in AOSE and other agent interaction frameworks, we extend the ROADMAP methodology and provide a framework for enhancing the analysis of interaction requirements through goal-oriented analysis and social modelling. More precisely, goal models provide the purpose of interaction, while social models provide the social dependencies and policies that govern interaction. We show how the resulting requirements specification, complemented by protocol descriptions, can inform the design of the system's interaction model. The resulting approach bridges the gap described above by linking high-level social concepts to low-level, domain-specific design decisions about interaction.

Feedback and control of micro-pumps

description: This thesis constitutes the documentation for a Doctoral research program undertaken at the Industrial Research Institute of Swinburne University of Technology (IRIS) between 2001 and 2005. The focus of the research was an investigation of the open- and closed-loop response of piezoelectric micro-pumps for micro-fluidic applications, particularly for chemical and biomedical environments. Specifically, in order to successfully integrate micro-devices into functional systems, it was important to address issues of real-time performance monitoring and control. The research addresses some of these problems in the context of a piezoelectric-driven micro-pump, equipped with interferometric displacement feedback, which was used to measure the dynamic displacement of the micro-pump actuator surface. During the course of the research, both a discrete component and a fully integrated (laboratory-on-a-board) test system were developed for open-loop characterization of the micro-pump. The laboratory-on-a-board system was also used for closed-loop control application. Measurements showed significant differences in actuator velocity, displacement and settling time between different pumping media. In addition, transient underdamped vibration of the actuator surface was observed during the rapid excursion and recursion phases of the pump movement while pumping air. These non-contact measurements could be used to determine the open-loop characteristics of a micropump and provide information for design improvement or failure detection/analysis. The technique could also be used to provide continuous measurement for adaptive compensation, so that the pump performance criteria are always satisfied. To this end, an automated interference fringe counting algorithm was developed, so that the steadystate parameters could be mapped into the closed-loop control elements in real time. The performance of this algorithm is discussed herein, together with the implications for optimal control of the micro-pump, and eventual integration of the interferometer and micro-pump systems. The research indicated that there were potential benefits in closed-loop control of micro-pumps, particularly where failure detection was required and for pumping of non-homogeneous media. The thesis also documents the relative performance differences between open and closed-loop control in homogenous media.

description: The objective of this research is to verify, through the use of a descriptive approach and a content analysis, the nature and degree of proximity of discursive stereotypes in journalistic writings from both Quebec and English Canada, more specifically, in the organization of the enunciation processes, the use of authentication and persuasion standards and the positioning of different points of view and centres of interest. The corpus of sixty articles is drawn from six mainstream newspapers: two English Canadian dailies and two Quebec newspapers, as well as two French newspapers serving as a control sample. A comparative analysis of the corpus reveals a proximity between the articles found in the Quebec newspapers and those from the English Canadian dailies. This similarity takes on several aspects. Regarding the enunciation processes, the four Canadian newspapers use more direct quotations than the two French dailies, in which there is a greater tendency to use the commentary function. An analysis of the transitional elements shows that the English and French newspapers in the Canadian corpus use a particular articulation based on an alternation between a direct or indirect quotation of a protagonist and an account of the facts, while the French newspapers use this type of construction less frequently. Moreover, a review of the rhetorical processes demonstrates a general tendency towards the respective homogeneity of the French and Canadian corpuses. Finally, an analysis of the focalization is based on a much smaller "sample" (one article from each newspaper), such that it would be more risky to assert any emerging trends. It is still a fad that a review of the modalizers well illustrates the impressionistic propensity of the French articles, compared to the Canadian ones. (Abstract shortened by UMI.)

description: Introduction Men with prostate cancer require long-term follow-up to monitor disease progression and manage common adverse physical and psychosocial consequences of treatment. There is growing recognition of the potential role of primary care in cancer follow-up. This paper describes the protocol for a phase II multisite randomised controlled trial of a novel model of shared care for the follow-up of men after completing treatment for low-moderate risk prostate cancer. Methods and analysis The intervention is a shared care model of follow-up visits in the first 12 months after completing treatment for prostate cancer with the following specific components: a survivorship care plan, general practitioner (GP) management guidelines, register and recall systems, screening for distress and unmet needs and patient information resources. Eligible men will have completed surgery and/or radiotherapy for low-moderate risk prostate cancer within the previous 8 weeks and have a GP who consents to participate. Ninety men will be randomised to the intervention or current hospital follow-up care. Study outcome measures will be collected at baseline, 3, 6 and 12 months and include anxiety, depression, unmet needs, prostate cancer-specific quality of life and satisfaction with care. Clinical processes and healthcare resource usage will also be measured. The principal emphasis of the analysis will be on obtaining estimates of the treatment effect size and assessing feasibility in order to inform the design of a subsequent phase III trial. Ethics and dissemination Ethics approval has been granted by the University of Western Australia and from all hospital recruitment sites in Western Australia and Victoria. Results of this phase II trial will be reported in peer-reviewed publications and in conference presentations.
