description: Movement coordination difficulties are a common feature of many neurodevelopmental disorders and may put children at risk for injury when crossing roads. However, relatively little is known about the set of cognitive and motor skills that underlie performance in complex perception-action tasks such as road crossing. The goals of the present investigation were to examine how executive functioning and processing speed skills impact motor timing performance in children with varying motor coordination skills and then to examine whether individual variation in these skills predicts how children cross virtual roads with continuous traffic.
description: One hundred and three children between the ages of 9 and 11 years completed behavioral tasks measuring executive functioning, processing speed, motor timing, and virtual-road crossing, along with a movement coordination assessment battery. Parents also completed questionnaires regarding children’s behavior and movement problems.
description: With regard to our first question, we found that processing speed mediated the relation between poorer executive functioning and more variable motor timing in the interval timing task. Processing speed also acted as a moderator of the association between movement coordination difficulties and more variable interval timing performance, such that children with both poorer movement coordination and slower processing speed exhibited the most variability on the interval timing task. With regard to the second question, we found that movement coordination difficulties and poorer motor timing skills predicted riskier gap selection and that poorer movement coordination skills and slower processing speed predicted poorer and more variable timing of entry in the road-crossing task.
description: These data suggest that children with poorer movement coordination and slower processing speed are most at risk for more motor timing difficulties and risky road crossing behavior. Future research should consider the transdiagnostic importance of movement coordination and processing speed difficulties with particular attention toward everyday safety implications.
Oprettelse af Pendlernettet i Movias område

description: Movia har gennem 2 år arbejdet med Pendlernettet. Behovet for et sådant projekt er opstået i forlængelse af Movias dannelse, strukturreformen og den måde som kommuner og regioner indkøber kollektiv bus- og lokalbanetrafik på. De sidste år, efter realiseringen af strukturreformen, har været turbulent for aktørerne og til tider også kunderne i den kollektive trafik. En gennemgående trend er, at ressourcerne satses der, hvor de største kundestrømme er. Dertil kommer en gennemgående trimning af de mindst benyttede afgange på den del af nettet, hvor efterspørgslen er spredt i tid og rum. Med Pendlernettet ønskes defineret et overordnet net, som er det der fremadrettet samarbejdes om og udvikles på. Med ro omkring Pendlernettet bliver der tid til at samarbejde om de strategiske langsigtede mål og satsninger. Pendlernettet sætter fokus på de største passagerstrømme, og princippet om ”mest til flest” forfølges. Pendlernettet omfatter 91 bus- og toglinjer, som ejes og administreres af kommuner, regioner og Movia. Dertil kommer Metro, S-tog og regionale baner. De 91 linjer fordeler sig på: • 50 mellembys linjer • 31 byinterne linjer • 10 lokalbaner Pendlernettet befordrer 73 % af passagerene og forbruger 56 % af alle køreplantimer for busserne og lokalbanerne i Movias område. Der er nogenlunde samme dækningsgrad, når man ser på hovedstadsområdet under ét, og når man ser på den øvrige del af Movia. Derimod er der forskelle kommunerne imellem i, hvor stor en andel af den kollektive transport, der er optaget i Pendlernettet. Det er oplagt, at den største passagerfremgang skal komme i Pendlernettet, hvor kommuner og regioner skal koncentrere deres indsats for at gøre det kollektive trafiktilbud bedst muligt set med kundeøjne.

description: A systematic study on the CHF in complex geometry has been carried out using a dumbbell shaped tube. The dumbbell shaped flow channel consists of two subchannels interconnected via a narrow gap, which simulates the two adjacent subchannels a in nuclear fuel bundle. The study was divided into two parts: mechanistic modeling and experimental investigation. Over 620 CHF data were obtained in a dumbbell-shaped tube with R-134a as working fluid. A wide range of flow conditions was covered. The gap size of dumbbell shaped tube was varied from 0, 0.15, 0.3, 0.5, 0.7, to 1 mm. This experimental investigation is one of the most systematic researches on the gap effect. It is found that the CHF trends against thermalhydraulic parameters in the dumbbell shaped tube are similar to those in circular tubes. No severe adverse effect was detected in the dumbbell-shaped tube under the test range of this study. The CHF decreases with decreasing gap size. On the average, as gap size decreases from 1 mm to zero CHF drops about 17.2% at a fixed inlet condition and about 11.5% at a fixed local condition. An analytical model for complex geometry, the partition model, was developed based on the annular flow assumption. The partition model divides a complex geometry cross section into two logical channels. Instead of making a complex two-dimensional description, the partition model calculates the complex geometry CHF by analyzing flow and heat transfer in two interactive one-dimensional flow channels. A new approach for the geometry effect on deposition was developed. A software package CHFA++ was developed based on the partition model to predict the CHF in complex geometries. The partition model predicts the CHF in dumbbell-shaped tubes and the gap effect with good accuracy. Several recommendations were made for further research on complex geometry CHF, including the optimization of the partition model, extending the application of the partition model to other complex geometries, and conducting experiments on the liquid film distribution.

description: A review of previous experimental, analytical, and numerical research conducted on pipe segments subjected to combined loading indicate that very few tests were reported on (a) pipes subject to load combinations involving axial tension, internal pressure, and bending, and (b) tests involving combinations of torsion, internal pressure, and bending. Within this context, an experimental program consisting of two full-scale test series on a total of eight pipe specimens is conducted. The specimens were made of X65 material (Specified Minimum Yield Strength=448MPa) with 508mm outer diameter (OD), and a nominal diameter-to-thickness ratio (D/t) of 80. In the first test series, specimens were subjected to combinations of internal pressure, axial tension, and bending and were aimed at (a) quantify the beneficial effect of axial tension on the magnitude of critical buckling strains of pipes and (b) determine whether or not the pipes are able to attain their modified plastic moment resistance as predicted by analytically derived plastic interaction relations. In the second test series, pipe specimens were subjected to load combinations involving internal pressure, axial tension, torsion, shear, and bending and were aimed to measure the pipe modified moment capacity. The moment vs. curvature relations, peak moment values, and local buckling behavior of the specimens as obtained from the experiments are documented. The peak moments obtained are compared to the analytically predicted moments. A nonlinear shell finite element model is also developed using the Finite Element Analysis (FEA) simulator ABAQUS in order to predict the moment capacity, critical strains, and the local buckling behavior of pipe specimens. Test results were observed to compare very well with FEA predictions for the moment capacities and buckling modes. Under certain combinations of axial tension and internal pressure, experiments and FEA show that pipes with Dt=80 are able to attain their modified plastic moment resistances. The FEA predicted longitudinal compressive strains were fairly good, but less reliable than the FEA predicted moment resistances. After demonstrating the ability of the FEA to reliably predict pipe modified moment capacity in previous and current research programs, a systematic FEA parametric study is conducted to investigate the effect of geometric properties (D/t) and loading conditions (torsion, axial force, and internal pressure) on the ability of the pipes to develop their modified plastic moment capacity. As a result of this parametric study, it was observed that the ability of the pipes to develop their plastic moment capacity is strongly dependant on axial force and D/t ratio. On the other hand, internal pressure and torsion are relatively less effective on this ability.

description: DSB’s passagerservice omfatter information til passagerer om rettidighed. Det aktuelle informationsformat angiver rettidighed sammen med en procentsats, f.eks.: ”I går var rettidigheden 90 %”. Selvom udsagnet virker enkelt, er det usikkert om det bliver opfattet korrekt af DSB’s kunder. Forståelse og formidling af numerisk information er et særligt problemfelt der har haft bevågenhed i økonomi, sundhedsvidenskab og psykologi. Efter model af et tidligere studie af et tilsvarende informationsformat (Gigerenzer et al.,2005) undersøgte vi hvordan togpassagerer tolker DSB’s informationsformat om rettidighed. I alt 381 rejsende på 3 forskellige danske jernbanestrækninger besvarede et skema med blot 4 spørgsmål om rettidighed. Det store flertal mente at begrebet rettidighed omfatter både afgangs- og ankomsttidspunkt, kun ca. 10 % mente, i overensstemmelse med DSB, at rettidighed alene refererer til et togs ankomsttidspunkt. De adspurgte angav vidt forskellige kriterier for rettidighed fra 0 min. til 1 time. Procentsatsen reference blev opfattet forskelligt; referencen blev opfattet som andelen af rettidigt ankomne tog (34,4 %) eller som andelen af strækninger hvor togene kørte rettidigt (41,4 %). Selvom få forstod udsagnet helt korrekt, angav flertallet at de foretrak rettidighedsinformation med reference til tog, enten som en procentandel eller som gennemsnitlig forsinkelse. Undersøgelsen viste, i fuld overensstemmelse med dens forlæg , at angivelse af procentsats uden referenceklasse åbner for forskellige tolkninger af budskabet i modtagergruppen. Resultaterne peger på at referenceproblemet bør tages alvorligt, når det er vigtigt at information bliver forstået korrekt af en modtagergruppe.

description: Individuals with borderline personality disorder (BPD) are characterized by emotional instability, impaired emotion regulation and unresolved attachment patterns associated with abusive childhood experiences. We investigated the neural response during the activation of the attachment system in BPD patients compared to healthy controls using functional magnetic resonance imaging (fMRI). Eleven female patients with BPD without posttraumatic stress disorder (PTSD) and 17 healthy female controls matched for age and education were telling stories in the scanner in response to the Adult Attachment Projective Picture System (AAP), an eight-picture set assessment of adult attachment. The picture set includes theoretically-derived attachment scenes, such as separation, death, threat and potential abuse. The picture presentation order is designed to gradually increase the activation of the attachment system. Each picture stimulus was presented for 2 min. Analyses examine group differences in attachment classifications and neural activation patterns over the course of the task. Unresolved attachment was associated with increasing amygdala activation over the course of the attachment task in patients as well as controls. Unresolved controls, but not patients, showed activation in the right dorsolateral prefrontal cortex (DLPFC) and the rostral cingulate zone (RCZ). We interpret this as a neural signature of BPD patients’ inability to exert top-down control under conditions of attachment distress. These findings point to possible neural mechanisms for underlying affective dysregulation in BPD in the context of attachment trauma and fear.

description: Young people from low socio-economic, minority, and other disadvantaged groups tend to be less physically active and to have poorer health. With this in mind, a community-academic partnership was formed to respond to the need for more physical activity programming targeting disadvantaged young people. The purpose of this thesis was to investigate the implementation and perceived impact of a new hip-hop dance program on the psychological, social, and physical well-being of youth aged 11 to 16 years living in a multicultural, disadvantaged community in Ottawa. In total, two studies were conducted. The first paper responds to the first project objective, which sought to better understand the needs, barriers, and facilitators to youth participation in physical activity in order to conceptualize the new program. Three focus groups were conducted with young people and parents from the target community. Findings suggested a need for more physical activity programming that was safe, accessible, age-appropriate, and culturally relevant. Hip-hop dance was reported as an appealing program option and thus, girls-only and co-ed formats of the program were implemented across two separate 3-month sessions, with funding from United Way Ottawa. The second and third objectives related to the evaluation of the new program, which involved a non-experimental pretest-posttest design from the perspective of the youth participant, parent, and program staff. Mixed methods were used, including document review, interview, focus group, observation, and questionnaire format. The second paper reviews the implementation of this new program. Overall, the consistency and quality of program implementation were moderately satisfactory; however, important concerns were noted, and the findings suggested that this program was only partially delivered as planned. Finally, the third paper reviews the success of the program. Quantitatively, there was a significant improvement in perceived hip-hop dance skills. The qualitative findings were more promising, showing positive perceived impacts across eight areas of well-being. Overall, the findings suggested that this intervention is a promising and relevant program for the promotion of youth psychological, social, and physical well-being, particularly if implementation concerns are addressed. Implications for the promotion of physical activity among this population and future research are reviewed.

description: The primary aim of this study was to explore attitudes of urban Brazilian citizens about dairy production. A secondary aim was to determine their knowledge and attitudes about four potentially contentious routine dairy cattle management practices: early cow-calf separation; zero-grazing; culling of newborn male calves; and dehorning without pain mitigation. To address the first aim 40 participants were interviewed using open-ended semi-structured questions designed to probe their views and attitudes about dairy production in Brazil, and 300 participants answered a questionnaire that included an open-ended question about the welfare of dairy cattle. Primary concerns reported by the participants centered on milk quality, which included the rejection of any chemical additives, but also animal welfare, environmental and social issues. The interviewees rarely mentioned animal welfare directly but, when probed, expressed several concerns related to this topic. In particular, participants commented on factors that they perceived to influence milk quality, such as good animal health, feeding, clean facilities, and the need to avoid or reduce the use of drugs, hormones and pesticides, the avoidance of pain, frustration and suffering, and the ability of the animals to perform natural behaviors. To address our second aim, participants were asked questions about the four routine management practices. Although they self-reported being largely unaware of these practices, the majority of the participants rejected these practices outright. These data provide insight that animal welfare may be an important issue for members of the public. Failure to consider this information may increase the risk that certain dairy production practices may not be socially sustainable once lay citizens become aware of them.

description: Functionalist traffic design aims at a rational organisation of movement from A to B in a segregated and uniform physical environment. Such urban areas have been criticized for being exclusively functional and lacking sensuous and social qualities. Recent research on mobilities challenges the more instrumental understanding of movement that underlies such traffic design. This research indicates that instrumental movement is only one aspect of ordinary journeys laden with meaning and experience to the wayfarers. In the paper we explore how we could think of the design of transit sites, if we operate insights on functional urban planning, on embodied practices and experiences of wayfaring, and on concrete small scale design concerns. We emphasise an integrated design agenda for those ordinary transit sites which is concerned with functional issues as well as the quality of life on the ground for the wayfarers who use the site. The data for our work concerns a transit site in the 1970s urban district of Aalborg Øst, Denmark. • We set out by introducing our approach to the site. • Second, we examine the functional layout of the transit site in Aalborg Øst and outline the design challenge which we are concerned with. • Third, we introduce an embodied mobile perspective through insights from the mobilities turn. • Fourth, through our own journey experience en route we present a mapping of the transit site. • We conclude by outlining a few propositions on the design challenge and design potentials, in relation to re-conceptualisation of the transit site, to mapping, and to design intervention. These propositions form part of our on-going work with urban mobility designs.

description: In Western concert dance, representations of identity on stage have come to be complicated by the passage of time. The stage is both a museum for history, as well as a site for contemporary performance. In dialogue with visual and performative markers of queer and Latinx performance, this project will provide a unique form of self-identification, filtered through multiple generations of choreographers. This thesis is projected as an exploration of identity throughout time; enacting memory in the present, imagining queer futures, and attending to the “prison” of here and now. Through the presentation of José Limón’s The Moor’s Pavane, a duet with colleague Juliet Remmers by Joshua Peugh, and a solo by Brenda Serrata Tally, I hope to collapse time, presenting my dancing body as a fabulation of dance’s history. Through these fabulations I aim to employ a queer rehearsal methodology, where my collaborators and I will investigate modes of transmitting dance that resist concert dance’s traditional relationship between choreographer, performer, and time. With a deep interest in gesture and inscription as simultaneous reifiers of the past and advancers of future, my goal is to interrogate through the moving body how dancing is not just a reflection of what has been, but also a gesture to what could be.

description: There is today an undisputed superiority of cars on any other means of transportation, both practically and psychologically. However, the reliance on cars as main means of transportation has led to a number of social and environmental problems. Mobility Management aims at managing the way people fulfil their mobility needs so that they rely less on their cars and start using alternatives such as bicycles and public transport. This article analyses the possibility to use businesses as vectors for introducing Mobility Management within social practices in Denmark in the light of the recent developments in this area.

description: Regulatory T cells (Tregs) offer new immunotherapeutic options to control undesired immune reactions, such as those in transplant rejection and autoimmunity. In addition, tissue repair and regeneration depend on a multitude of tightly regulated immune and non-immune cells and signaling molecules. There is mounting evidence that adequate innate responses, and even more importantly balanced adaptive immune responses, are key players in the tissue repair and regeneration processes, even in absence of any immune- related disease or infection. Thus, the anti-inflammatory and anti-apoptotic capacities of Treg can affect not only the effector immune response, creating the appropriate immune environment for successful tissue repair and regeneration, but growing evidence shows that they also have direct effects on tissue cell functions. Here we summarize the present views on how Treg might support tissue regeneration by direct control of undesired immune reactivity and also by direct interaction with non-immune tissue cells. We describe tissue-resident Treg and their specific phenotypes in skin, visceral adipose tissue, and skeletal muscle. In addition, we touch on the topic of osteoimmunology, discussing the direct interactions of Treg with bone-forming cells, such as osteoblasts and their mesenchymal stromal cell (MSC) progenitors—a field which is under-investigated. We hypothesize a cross-talk between Treg and bone-forming cells through the CD39–CD73-(adenosine)-adenosine receptor pathway, which might also potentiate the differentiation of MSCs, thus facilitating bone regeneration. This hypothesis may provide a road map for further investigations on the cross-talk between the immune and the skeletal system, and also enable the development of better strategies to promote bone repair and regeneration.

description: This thesis investigates rhythmic motion in-selected chorale preludes from J. S. Bach's Orgelbuchlein collection. It examines how layers of motion, produced from the contrapuntal layering of voices, interact within each selected chorale prelude. It shows how layers of motion either align and produce synchronous rhythmic motion or misalign and produce non-synchronous rhythmic motion. In particular, this thesis investigates how alternations between synchronous and non-synchronous layers of motion correspond to and articulate both phrase form and tonal structure in these works.

description: Why sex is the dominant mode of reproduction given its extreme costs is an evolutionary enigma deemed the ‘queen of problems’ in biology. One explanation for the predominance of sex is that asexual reproduction faces inherent evolutionary challenges (e.g., limited access to novel genetic variability) that are sufficient to overwhelm the substantial benefits of not engaging in sex. I here seek deeper understanding of the consequences of asexuality by leveraging the unusual reproductive mode polymorphism found in four species of Peltigera lichen and in Potamopyrgus antipodarum freshwater snails to compare how genes critical to sex (meiosis and sperm genes) and highly conserved genes important outside of the context of sex (mitosis genes) are evolving differently relative to one another in sexual vs asexual backgrounds. I find that asexual Peltigera and P. antipodarum are accumulating more mildly deleterious mutations (i.e., mutations that cause amino acid changes) than sexual counterparts, and to a more extreme extent in genes specific to sex. I also find that in asexual P. antipodarum, the increased accumulation of amino acid changes and presence of frame-shifting indels in sperm genes is associated with the presence of morphologically abnormal sperm. Together, these results point toward a genome-wide fitness cost for lineages that reproduce asexually and emphasize the likelihood that transitions to asexuality are irreversible. These findings also reveal key genomic consequences of the lack of sex for asexual lineages and highlight some long-term benefits of sex with respect to mutational clearance.
Politique et religion dans la philosophie de Thomas Hobbes.

description: La problématique politique de Hobbes se présente comme une charnière entre deux types de problématiques: la problématique théologique, où la politique était englobée par la transcendance, et la «moderne» problématique anthropologique qui fonde la politique sur l'essence et la volonté de l'homme. La pensée de Hobbes n'est réductible à aucune de ces deux problématiques. De ce double mouvement découle une tentative d'autonomisation du discours politique: le champ politique devient objet et matière de science, il requiert une réalité autonome. Cette autonomisation peut être assimilée à une libération du champ politique: il se dégage de l'emprise de la transcendance, il n'est plus un «moment» du discours philosophique, métaphysique ou religieux. L'autonomie est ainsi un retour sur lui-même du discours politique. Par là même, le problème religieux est envisagé sous l'angle de la notion de pouvoir. Le problème de Hobbes s'énonce ainsi: quelle est l'organisation politique qui peut atteindre au maximum de puissance, au maximum de sécurité? Le problème politique, c'est le problème du pouvoir. Et le pouvoir requiert un absolu incompatible avec un absolu de type religieux. À plusieurs reprises, Hobbes précise qu'il écrit sur le pouvoir en tant que tel, sur ses mécanismes. Il veut parler du pouvoir dans l'absolu, et non de ses formes concrètes et contingentes d'exercice. L'objectif est double: d'une part faire une oeuvre «réaliste», «utile», tenant compte de la réalité des passions humaines (permanentes), et de la situation présente (économique, politique, religieuse) de l'Angleterre au dix-septième siècle. D'autre part faire une oeuvre scientifique, énonçant des vérités spéculatives, des «règles», des «théorèmes» politiques valables en tous les temps et en tous les lieux. Il s'agit en quelque sorte de rendre la science efficiente. Le problème primordial de l'homme: sa survie au milieu de ses semblables, n'a jamais fait l'objet d'une étude systématique. Sous le prétexte que la politique est le domaine où s'affrontent les passions humaines, on a toujours négligé une approche scientifique du problème. Plus exactement, on a laissé se répandre de vaines chimères, des mauvaises littératures sur le sujet. On trouve en germe, chez Hobbes, une idée proche de Rousseau: les hommes ont été corrompus (par les mauvaises doctrines, par la théologie, par la religion) et ainsi, ils ne cessent de se combattre et de renverser leurs princes: «Si j'avais écrit, comme sur une table rase, dans des coeurs purs, j'aurais pu être plus bref...mais comme je savais que les esprits avaient auparavant été barbouillés de doctrines contraires, j'ai pensé devoir expliquer cela plus longuement» 2 conclut Hobbes.

description: Unhealthy behaviours contribute significantly to chronic disease. Longitudinal studies report improvements in the health of older adults after positive changes in health behaviours. A conceptual model of healthy behaviours in older adults was developed based on prospective evidence. Structural equation modeling was used to test specific hypotheses in a sample of 980 family practice patients over 65 years who attended a cardiovascular health awareness session. A model was specified that included variables reflecting health status, health-related quality of life, physician counseling and patient knowledge (p=0.02, CFI=0.97, RMSEA=0.039). Health-related quality is the most important pathway to healthy lifestyle behaviours (beta=0.41). Physician counseling is the most important pathway to healthy self-care behaviours (beta=0.64). This preliminary model provides evidence of the importance of health-related quality of life and physician counseling for influencing healthy behaviours among older adults.
Nomadicity and the evolution of applications, networks and policy

description: A number of behavioural observations point to a preference and willingness to pay for communications technologies that support mobile and nomadic use. This paper considers these observations and the implications for the evolution of mobile and fixed networks. It then considers whether there are wider external social benefits and the possible implications for public policy. Mobile and fixed are both substitutes and complements. Consumers with low bandwidth and, in particular, low capacity (gigabytes per month) requirements may opt for mobile broadband only. Consumers with low bandwidth and high capacity requirements might choose to meet their need for capacity with copper, complemented by wireless. Demand for fibre may be more limited. To meet demand for mobile bandwidth and capacity, fibre can be run to mobile base stations, but this only requires a network of around 1/2000th the density in terms of points of connection of a fibre to the home network. Demand for fibre to the home is limited to those who are willing to pay for high bandwidth and capacity. Some key questions addressed in this paper include whether external social benefits arise from mobile and fixed network access, whether the incremental external social gains from a move from current to next generation networks are material and whether they are likely to differ between mobile and fixed networks. We conclude that such gains are likely to be significantly larger for mobile than for fixed networks since wide area coverage and smart mobile devices can support applications that fixed cannot, mobile is likely to contribute more to getting the final third of the population online and spectrum reallocation would result in gains from trade that are not privately appropriable since spectrum utilised for broadcasting is generally non-tradable. These questions have a direct implication for policy decisions: priority should be given to spectrum reallocation for mobile use (including public expenditure as required) and removal of barriers to commercial investment in fibre, including possible regulatory barriers to copper network retirement and price differentiation for wholesale fibre access.

description: Current adenovirus retargeting strategies are unable to target the virus to specific cell types. In this study, we investigated whether fusion of a single-chain antibody, MR1, to the capsid protein IX (pIX) could target the virus to cancer cells expressing EGFRvIII. We show that addition of an endoplasmic reticulum signal peptide to pIX-MR1 significantly increased the ability of the fusion protein to bind its ligand. Use of the human CMV promoter rather than the native pIX promoter permitted a greater accumulation of the protein within the cell. Finally, addition of the HIV-1 Tat NLS caused pIX-MR1 to relocalize to the nucleus, the site of capsid assembly. Taken together, these results provide a foundation to design Ad vectors targeted to specific cells through the use of single-chain antibodies. Ultimately, the development of a tropism modified Ad vector would result in a tailored treatment for a particular acquired genetic disease.

description: Before Vatican II, marriage was often considered, or at least popularly expressed, as a union of bodies; that is to say, marriage was an exclusive contract by which a man and a woman mutually handed over their bodies for the purpose of acts which led to the procreation of children. Matrimonial jurisprudence was primarily focused on this marital contract. With the advent of Vatican II and its emphasis on the personalist notion of marriage, a new age dawned whereby canonists, especially auditors of the Roman Rota, were henceforth to view marriage as a union of persons. "Person" is more than a "body"; rather, a person is an individual consisting of wants, needs, desires, impulses, hopes and dreams, whose life experience has been shaped by the milieu---cultural, familial, religious---from which he or she comes. "Union" is not only simply understood as a "contract", but also is now once again recognized as a "covenant", a concept which, at least in the Latin Church, was prevalent until the 12th century. One of the canons of the 1983 CIC, although almost identical in wording to its predecessor in the 1917 CIC, but which now must be understood and interpreted in light of the teachings of Vatican II, is canon 1096 which pertains to the effect of ignorance on matrimonial consent. Given the current appreciation of marriage founded in the teachings of Vatican II, especially in Gaudium et spes, reiterated by Popes Paul VI and John Paul II and described in the Catechism of the Catholic Church, complicated by today's western society's stress on individualism and permeated by a divorce mentality, what is the impact of this canon on matrimonial consent? How can its meaning, once understood as being wider than merely the sexual act itself, be better utilized by those in tribunal ministry? This is the major thrust of the present work. The research of the history and development of the concept of ignorance in canonical writings, how its understanding broadened especially after Vatican II and our conclusions on how to apply its richness to marriage nullity led us to expand the use of this canon: how it can aid in the development of pre-marital preparation programs which would not only possibly help prevent couples from being ignorant of the essence of marriage but also help them to appreciate this richness more deeply in their own lives so that marriage truly can become, as we read in canon 1055, "a partnership of the whole of life which is ordered by its nature to the good of the spouses and the procreation and education of offspring". It is our sincere hope that this study will be of benefit to all who read it.

description: The Kilo-Degree Survey (KiDS) is a multi-band imaging survey designed for cosmological studies from weak lensing and photometric redshifts. It uses the European Southern Observatory VLT Survey Telescope with its wide-field camera OmegaCAM. KiDS images are taken in four filters similar to the Sloan Digital Sky Survey ugri bands. The best seeing time is reserved for deep r-band observations. The median 5σ limiting AB magnitude is 24.9 and the median seeing is below 0.7 arcsec. Initial KiDS observations have concentrated on the Galaxy and Mass Assembly (GAMA) regions near the celestial equator, where extensive, highly complete redshift catalogues are available. A total of 109 survey tiles, 1 square degree each, form the basis of the first set of lensing analyses of halo properties of GAMA galaxies. Nine galaxies per square arcminute enter the lensing analysis, for an effective inverse shear variance of 69 arcmin-2. Accounting for the shape measurement weight, the median redshift of the sources is 0.53. KiDS data processing follows two parallel tracks, one optimized for weak lensing measurement and one for accurate matched-aperture photometry (for photometric redshifts). This technical paper describes the lensing and photometric redshift measurements (including a detailed description of the Gaussian aperture and photometry pipeline), summarizes the data quality and presents extensive tests for systematic errors that might affect the lensing analyses. We also provide first demonstrations of the suitability of the data for cosmological measurements, and describe our blinding procedure for preventing confirmation bias in the scientific analyses. The KiDS catalogues presented in this paper are released to the community through http://kids.strw.leidenuniv.nl.

description: Background: Lignocellulose originating from renewable and sustainable biomass is a promising alternative resource to produce biofuel. However, the complex component, especially high moisture content, leads to a higher cost of transportation and processing. The instant catapult steam explosion (ICSE) pretreatment can exploit the intracellular water of lignocellulosic materials and convert into vapors leading towards the breakdown of the feedstock during the explosion process. However, it is necessary to study the impact of moisture content on the pretreatment. Results: The sugar yield of wet feedstock after ICSE pretreatment reached 88.05%, which was higher when compared to dried and untreated biomass. The utilization of wet feedstock decreased the production of inhibitor and improved the carbohydrate content in ICSE-treated biomass. There occurred a shrinkage of feedstock after drying process and the mechanical breakage upon ICSE pretreatment. Moreover, not all water was converted into vapor to cause breakage in the lignocellulose. Conclusion: ICSE has shown to be preferably suitable to pretreat wet sweet potato vine with high moisture content, either fresh or soaked biomass that has been dried before. By using these materials, it would have a higher sugar yield and lower inhibitor production after pretreatment. Based on these advantaged aspects of ICSE platform, two potential strategies are proposed to improve the economic and environmental impacts of pretreatment.
Fluorescence detection of carbon-centered radicals in different systems.

description: The work presented in this thesis is primarily focused on the development of pre-fluorescent probes for carbon-centered radicals. Coumarin-TEMPO and quinoline-TEMPO adducts have been prepared by tethering a free radical nitroxide group such as 2,2,6,6-tetramethyl-1-piperidinyloxy (TEMPO) to coumarin and quinoline fluorophores through an ester bond. Some organic derivatives of the quinoline-TEMPO adduct are also presented. Intramolecular quenching of fluorescence due to a spin-exchange mechanism between the singlet excited state of the fluorophore and the doublet ground state of the nitroxide and the restoring of fluorescence due to coupling with a carbon-centered radical are the conceptual bases for this research study.
