title: The breeding biology and ecology of the White-necked Picathartes Picathartes gymnocephalus temminck 1825, in Sierra Leone
Creators: name: Thompson, Hazell Shokellu
Publisher: name: The Open University
Year: 1998

description: This thesis investigates the ecology, taxonomic affinities and conservation management in Sierra Leone of a threatened West African forest bird, the White-necked Picathartes Picathartes gymnocephalus, which has not been previously studied in detail. The incubation and nestling periods (20 and 25 days) respectively were longer than is usual for most tropical passerines. In most cases, one clutch of two eggs was laid between June and December, immediately followed by moult between January and May (the dry season). Peaks in egg laying occurred 1-2 months after the maximum monthly rainfall. Both parents cared for the young and fed nestlings disproportionately more earthworms, frogs, millipedes and earwigs in relation to their abundance in the environment. Nestlings fledged when still as much as 30% below adult size. Food abundance peaked in both forest and farmbush (forest regrowth) habitat at the start of the wet season and in the early part of the dry season; coinciding with the period immediately prior to egg-laying and with dispersing fledglings respectively. Potential Picathartes prey were more abundant in farmbush than forest habitat. The proportion of eggs laid that resulted in fledged young was 22.9% and productivity was 0.22 chicks per adult. Nest predation was the main cause of nest failure but infanticidal behaviour played a significant role. A substantial number of non-breeding birds were apparently present in populations and infanticidal behaviour may have been a consequence of competition for limited nest sites. Population density was estimated as 0.37 individuals km-' and the total population in Sierra Leone as about 1100. Local populations in forest reserves are close to the theoretical minimum for long-term viability in all cases but populations are apparently stable or declining only very slowly. Abandonment of colonies was associated with habitat degradation but there was also evidence that Picathartes may be fairly tolerant to disturbance in some areas. Phylogenetic analysis using mitochondrial DNA of the cytochrome b gene suggests that Picathartes is more closely related to the thrush-babbler assemblage than the crows.

description: The purpose of this study was to evaluate the pan evaporation method for scheduling irrigation of a sweet pepper (Capsicum annuum) crop grown on an Oxisol at the University of Puerto Rico Agricultural Experiment Station at Isabela, PR. Irrigation scheduling refers to a procedure in which water is applied to the field according to the water demand by the crop. Ideally, water should be applied at a rate equal to the potential evapotranspiration rate of the crop minus the effective rainfall. However, when plastic mulch is used to eliminate weed growth, as is common in vegetable production in Puerto Rico, much of the rainfall runs off and is not available to the plants. To minimize the possibility of crop water stress when plastic mulch is used, water should be applied at a rate equal to the crop evapotranspiration rate. If the contribution from rainfall is assumed to be zero, but in fact some rain enters the soil through holes in the plastic, this may produce deep percolation. Deep percolation is undesirable (except as required for salinity control) because it represents a loss of water and fertilizer, and may also contribute to groundwater contamination. The daily pan evaporation-derived evapotranspiration (ETpan) was obtained from the product of pan evaporation (Epan), a pan coefficient (Kp) and the evapotranspiration crop coefficient (Kc). The contribution of water from rainfall was assumed to be zero. However, some rainfall was observed to enter through holes in the plastic mulch where the pepper plants were located. This contribution of water however, was spatially variable and difficult to quantify. Through calibration of a water balance equation, on average twenty five percent of the rainfall was found to enter the soil beds. Evaluation of the pan method for scheduling irrigation was based on comparison of ETpan with the Penman-Monteith-based evapotranspiration (ETC), estimates of deep percolation, measured vertical hydraulic gradients, and measured soil moisture distribution. Seasonal estimates of ETpan and ETC were 350 mm and 401 mm, respectively. The estimated seasonal deep percolation was 60.9 mm. A simulated irrigation schedule using the Penman-Monteith method resulted in even greater seasonal deep percolation (127.7 mm). Vertical hydraulic gradients were observed to be downward throughout a significant portion of the season, and observed moisture content distributions below the root zone clearly indicated that deep percolation was occurring.

description: On-farm trials were conducted over two seasons to evaluate yield performance of eggplant (Solanum melongena L.) cultivars under organic crop management system. In 1998, cultivars included 7 hybrids with oval or egg-shaped fruit and 4 open-pollinated Oriental type, elongated fruit shape. Trial in 2001 consisted of 5 hybrids and 3 Oriental type cultivars. Plants were spaced 61 cm within rows 1.22 m apart. Both trials were established using a randomized complete block design with three replications. An organic crop management system was adopted in growing and maintaining the crops. These consisted of organic insect sprays, cow manure and grass straw mulch. Data were collected on number of harvests, fruit size and marketable yield. Significant differences (P<0.05) were observed in marketable yield among cultivars within hybrids and openpollinated in both seasons. In 1998, top yielding hybrid cultivars were 'Black Nite' (32.4 t ha"1), 'Black Bell' (29.5 t ha1) and 'Black Beauty' (28.8 t ha"1). Cultivar 'Trinidad Long' produced the highest yield among the open-pollinated type. Hybrid cultivars 'Black Nite', 'Black Bell' and 'Black Beauty' maintained top yields in 2001 whereas cultivar 'Megal' produced the highest yield (18.0 t ha"1) among the Oriental type. Common insect pests were mealy bugs, aphids, flea beetles and mites. Organic sprays were not very effective, but reduced pest population resulting in minimal damage. Marketable yields were comparable with or higher than those reported in previous evaluation trials which suggests that improved eggplant cultivars can be grown successfully under organic management system without the use of chemical fertilizers and pesticides.
Gamma-ray burst early afterglows: reverse shock emission from an arbitrarily magnetized ejecta

description: Evidence suggests that the gamma-ray burst (GRB) ejecta is likely magnetized, although the degree of magnetization of the ejecta is unknown. We derive a rigorous analytical solution for the relativistic 90 degree shocks under the ideal MHD condition, and use them to study the reverse shock emission properties of an arbitrarily magnetized ejecta. Contrary to the previous belief, we find that strong relativistic shocks still exist in the high-sigma limit. Assuming a constant density of the circumburst medium, we study the shell-medium interaction in detail and categorize various critical radii for shell evolution. With typical GRB parameters, a reverse shock exists when sigma is less than a few tens or a few hundreds. The shell evolution can be still categorized into the thick and thin shell regimes, but the separation between the two regime now depends on sigma and the thick shell regime greatly shrinks at high-sigma. The early optical afterglow lightcurves are calculated for GRBs with a wide range of the sigma values. We find that the reverse shock emission level increases steadily with sigma initially, but starts to decline when sigma becomes larger than unity. In the high-sigma regime the reverse shock peak is usually broadened due to the separation of the shock crossing radius and the deceleration radius in the thin shell regime. The early afterglow data and tight upper limits of known GRBs could be understood within the theoretical framework developed in this paper, with the inferred sigma value varying in a wide range.

description: In der Ziegelei von Leitmeritz (= Litoměrice) (Nordböhmen) ist eine reich gegliederte Schichtenfolge jungpleistozäner Lösse und fossiler Humusböden aufgeschlossen, die zeitlich der Würmeiszeit bzw. dem letzten Interglazial und dem Göttweiger Interstadial entspricht. Das Profil wurde eingehend stratigraphisch und petrographisch untersucht. In zwei Humushorizonten des erwähnten Interstadials wurde eine reiche Molluskenfauna festgestellt, die größtenteils aus wenig temperaturanspruchsvollen Steppenarten besteht und sich sowohl von der letztinterglazialen Fauna als auch von den Lößgesellschaften stark unterscheidet. Aus der Analyse der untersuchten Schneckenfaunen ergibt sich, daß das Klima des Göttweiger Interstadials verhältnismäßig trocken und winterkalt war. Denselben Charakter weisen auch die Molluskenfaunen auf, die im Göttweiger Interstadial an anderen tschechoslowakischen Fundstellen festgestellt wurden. Aus dem gegenseitigen Vergleich verschiedener Lößprofile in der Tschechoslowakei, Österreich und Süddeutschland ergibt sich die Möglichkeit, daß im fossilen Bodenkomplex, der als Stillfried A bezeichnet wird, nicht nur das Letzte Interglazial sondern auch das Göttweiger Interstadial verborgen sind. Wenn es gelingen würde, diese Voraussetzung durch verläßliche Beweise zu bestätigen, wäre der Hauptwiderspruch in der stratigraphischen Untergliederung der würmeiszeitlichen Lößprofile gelöst. Aus vergleichenden Untersuchungen der letztinterglazialen und würminterstadialen Molluskenfauna ist ersichtlich, daß man das Interglazial als Schwankung einer höheren Ordnung vom Interstadial scharf unterscheiden muß, wobei man aber in Betracht ziehen sollte, daß das Göttweiger Interstadial wieder eine Schwankung höherer Ordnung ist als die anderen Interstadiale der Würmeiszeit, für welche in Übereinstimmung mit dem Vorschlag von H. Movius (1957) der Termin „Oszillation" geeignet wäre.

title: The meaning of 'challenging behaviour' for support staff and home managers of residential learning disability services
Creators: name: Whittington, Adrian Sinclair
Publisher: name: The Open University
Year: 1998

description: Staff perceptions of challenging behaviour and other "challenging problems" in their work with people with learning disabilities are likely to have a significant influence on how they respond to clients and to interventions by Clinical Psychologists. However, accounts of staff perceptions have failed to produce a coherent theory grounded in the experience of staff themselves. The aim of the present study was to develop a theory of how staff describe and explain challenging problems. Grounded theory methodology was used. Ten Support Workers and eight Home Managers in residential learning disability services described their understanding of a challenging problem in relation to a client during senustructured interviews. Client behaviour was the most commonly cited problem. Results suggested that staff face dilemmas concerning whether to see behaviour as communication or a behaviour problem, how to balance firm responding with kindness, and how to deal with their unpleasant feelings evoked by the work. A theoretical account of the results suggested that staffs' emotional distance from or closeness to a client determines how they resolve the dilemmas. The theoretical account should be subjected to further testing. It implies that staff need to be aware of their emotions and personal motivations in their work if they are to resolve the work dilemmas in the best interests of clients. Clinical Psychologists may be well placed to facilitate personal development programmes for staff to foster this awareness.

description: Chemical reactions in multidimensional driven systems are typically described by a time-dependent rank-1 saddle associated with one reaction and several orthogonal coordinates (including the solvent bath). To investigate reactions in such systems, we develop a fast and robust method ---viz., local manifold analysis (LMA)--- for computing the instantaneous decay rate of reactants. Specifically, it computes the instantaneous decay rates along saddle-bound trajectories near the activated complex by exploiting local properties of the stable and unstable manifold associated with the normally hyperbolic invariant manifold (NHIM). The LMA method offers substantial reduction of numerical effort and increased reliability in comparison to direct ensemble integration. It provides an instantaneous flux that can be assigned to every point on the NHIM and which is associated with a trajectory ---regardless of whether it is periodic, quasi-periodic, or chaotic--- that is bound on the NHIM. The time average of these fluxes in the driven system corresponds to the average rate through a given local section containing the corresponding point on the NHIM. We find good agreement between the results of the LMA and direct ensemble integration obtained using numerically constructed, recrossing-free dividing surfaces.

description: We study frequency dependent (FD) input-output schemes for signal-recycling interferometers, the baseline design of Advanced LIGO and the current configuration of GEO 600. Complementary to a recent proposal by Harms et al. to use FD input squeezing and ordinary homodyne detection, we explore a scheme which uses ordinary squeezed vacuum, but FD readout. Both schemes, which are sub-optimal among all possible input-output schemes, provide a global noise suppression by the power squeeze factor, while being realizable by using detuned Fabry-Perot cavities as input/output filters. At high frequencies, the two schemes are shown to be equivalent, while at low frequencies our scheme gives better performance than that of Harms et al., and is nearly fully optimal. We then study the sensitivity improvement achievable by these schemes in Advanced LIGO era (with 30-m filter cavities and current estimates of filter-mirror losses and thermal noise), for neutron star binary inspirals, and for narrowband GW sources such as low-mass X-ray binaries and known radio pulsars. Optical losses are shown to be a major obstacle for the actual implementation of these techniques in Advanced LIGO. On time scales of third-generation interferometers, like EURO/LIGO-III (~2012), with kilometer-scale filter cavities, a signal-recycling interferometer with the FD readout scheme explored in this paper can have performances comparable to existing proposals.

description: Neem trees offer the potential of a locally available biological insecticide and the possibility of improving agricultural in the Virgin Islands. Neem is a hardy tree with rapid growth whose leaves and fruits can be made into a variety of products with insecticidal properties. Producing and utilizing such products would not only reduce farmers' expenses through decreased dependence on costly imported chemicals, but would also be more environmentally sound. Agricultural run-off and non point source pollution are quickly becoming major concerns in the Virgin Islands. This project directly addresses these concerns by testing two environmentally sound methods of organic insect control on a widely grown crop, sweet potato.Four treatments (traditional spraying, commercially available neem extract, neem mulch treatment and no input) were compared for their effect on crop yield and incidence of pest damage. Sweet potato weevil (SPW) is the primary pest problem with this crop. Data was collected in accordance with previous SPW studies in the Virgin Islands (Crossman et al. 1993). Additional measurements were taken on the height and spread of vegetative material, crop canopy closure and incidence of foliar pests. Harvested storage roots were divided into three size categories (below market, medium and jumbo), weighed and percent infestation and damage of SPW recorded. Traditional spraying produced the greatest number of marketable storage roots. Neem mulch treatment had the highest average weight/storage root and greatest total yield. The Neem spray was the most effected by SPW, however results may have been influenced by the minimal infestation of

description: Ein neu entwickeltes Verfahren zur pollenanalytischen Untersuchung von Lössen ist nach Abschätzung der zahlreichen möglichen Fehlerquellen durchaus in der Lage, bei echten und verwitterten, aber nicht verschwemmten Lössen Beiträge zur Kenntnis der hochglazialen Vegetationsgeschichte desjenigen Abschnittes der Letzten Eiszeit (aber auch der vorangegangenen Eiszeiten) zu liefern, der bisher vegetationsgeschichtlich nicht recht hatte erfaßt werden können, nämlich der Löß-Zeit. Die berühmte Abfolge fossiler Böden bei Oberfellabrunn, die unter der Bezeichnung des „Fellabrunner Komplexes" („Stillfried A") bekannt geworden ist, muß aufgeteilt werden inden in das letzte Interglazial gehörenden unteren braunen Verlehmungshorizont, sowie in die beiden oberen Humushorizonte, die als Bildungen der Letzten Eiszeit in das Amersfoort- und das Brørup-Interstadial fallen. Die Klimabesserung des Stillfried-B-Interstadials hatte in dem Untersuchungsgebjet zu einer teilweisen Wiederbewaldung geführt, wobei allerdings die im wesentlichen als subalpin zu kennzeichnenden Fichtenwälder wahrscheinlich nur den größeren Flüssen gefolgt sind, sich hier mit Eschen-Ulmen-Auenwäldern vereinigend, wohingegen die umgebenden Löß-Plateaus weiterhin von Steppengesellschaften eingenommen waren. Die Lösse wurden im Ostteil Niederösterreichs während des Jungpleistozäns in gramineenreichen Kräutersteppen abgelagert, die zeitlich und räumlich in unterschiedliche Typen gegliedert waren. Zeitweise, so besonders nach dem Stillfried-B-Interstadial, waren diesen offenen Pflanzengemeinschaften Elemente der Tundra beigemischt, ohne daß es zur Ausbildung echter Tundren-Gesellschaften gekommen ist. Bei einem großräumigen Vergleich der letzteiszeitlichen offenen Vegetationstvpen mit heutigen Tundren-, Steppen- und Halbwüsten-Gesellschaften wird die bemerkenswerte Tatsache offenkundig, daß die letzteiszeitlichen offenen Pflanzengemeinschaften nicht mit heutigen Biocönosen identisch sind, sondern daß sie einen ganz anderen Charakter getragen haben.

description: The aim of the paper was to estimate the economic value of bees in Poland in the years 2005-2014. There was estimated the value of produced bee honey and yield value of major entomophilous crops (i.e. rape and turnip, apples, pears, plums, sour cherries, sweet cherries, strawberries, currants, raspberries, gooseberries and buckwheat). In the paper were used data from the Central Statistical Office and the Research Institute of Horticulture, Apiculture Division in Pulawy and literature of the subject. To estimate the missing data was used deductive method. The estimated value of honey production in Poland ranged from 75.2 million in 2005, to 163.2 million USD in 2011. The value of crops’ pollination by using dependence ratio method was estimated about 10-15 times higher than the value of honey and varied from 698.7 million in 2005 to 1,784 million USD in 2013. In the structure of value pollination in 2014 apple trees had 39%, rape and turnip 30% and 11% raspberries. The results indicate the important role of bees in the human economy. The importance of beekeeping for bioeconomy may increase due to the growing needs of pollination, or the possibility of innovative use of bee products.

description: We consider constraints on the topology of closed 3-manifolds that can arise as hypersurfaces of contact type in standard symplectic $R^4$. Using an obstruction derived from Heegaard Floer homology we prove that no Brieskorn homology sphere admits a contact type embedding in $R^4$, a result that has bearing on conjectures of Gompf and Kollár. This implies in particular that no rationally convex domain in $C^2$ has boundary diffeomorphic to a Brieskorn sphere. We also give infinitely many examples of contact 3-manifolds that bound Stein domains but not symplectically convex ones; in particular we find Stein domains in $C^2$ that cannot be made Weinstein with respect to the ambient symplectic structure while preserving the contact structure on their boundaries.

description: We present the review of various methods of detection of magnetic field strengths in the nearest regions of the active galaxy nuclei (AGN) which are the high energetic machines. Original spectropolarimetric method developed in the Pulkovo Observatory allows us to determine the magnitude and geometry of the magnetic field in the region of the optical and more hard electromagnetic radiation. The results of theoretical calculations are compared to the results of spectropolarimetric observations of AGN. We used the method of determining magnetic fields through the spectrum synchrotron radiation in the region of synchrotron self-absorption. As the magnitude of magnetic field of the extragalactic source depends very strongly on the angular size of extragalactic source and therefore on the photometric distance the calculated magnetic field magnitudes depends very strongly on the definite cosmological model. This result allows us to present the new method for determination of the most important cosmological parameters including dark matter and dark energy parameters.

description: Here we propose that the excess flux of particle events of energy near 1 EeV from the direction of the Galactic Center region is due to the production of cosmic rays by the last few Gamma Ray Bursts in our Galaxy. The basic idea is that protons get accelerated inside Gamma Ray Bursts, then get ejected as neutrons, decay and so turn back into protons, meander around the inner Galaxy for some time, and then interact again, turning back to neutrons to be observed at our distance from the Galactic Center region, where most star formation is happening in our Galaxy. We demonstrate that this suggestion leads to a successful interpretation of the data, within the uncertainties of cosmic ray transport time scales in the inner Galaxy, and in conjunction with many arguments in the literature.

title: Wittgensteinian descriptivism and concepts of self-renunciation
Creators: name: Thomas, Emyr Vaughan
Publisher: name: The Open University
Year: 1997

description: Part I presents a systematic presentation of what is termed 'the Wittgensteinian position', broken down into eight theses, each of which is thought of as intrinsic to self-renouncing faith. Part II consists of three case-studies examining the conception of self-renouncing faith found in the works of Francois Mauriac, Georges Bernanos, and Patrick White. Distinct divergencies from many of the Wittgensteinian theses are unearthed. Part III traces the roots of each of the Wittgensteinian theses to their sitz im leben in a strain of neo-Romanticism centred on securing independence of the world. Connections are made to Tolstoy, Emerson, Rilke, Trakl and Von Hofmannsthal. Part IV argues that each case study in Part II runs counter to the Wittgensteinian position in one of three ways: (1) not having some theses which are proposed by the Wittgensteinian position to be intrinsic to self-renouncing faith; (2) deeming some theses which are proposed by the Wittgensteinian position to be intrinsic to self-renouncing faith as either (2.1) not inherently selfrenouncing or (2.2) actually incompatible with the understanding of selfrenunciation exemplified in the case-study; (3) having a different logical structure to its model of self-renouncing belief from that of the Wittgensteinian position. Points (1), (2) and (3), and particularly points (2.1) and (2.2), suggest that self-renouncing faith is not the unitary phenomenon assumed by the Wittgensteinian position. The casestudies represent three distinct models of self-renouncing faith. These models have no place for the self-concern that characterises the Weltbild of self-concern with which the Wittgensteinian position is impregnated. There follows a broad discussion of the implications of the above findings for the Wittgensteinian position, including Wittgenstein's status as a religious thinker, the way a descriptivist methodology should be understood, the blanket exclusion of the metaphysical from religious belief and the over-simple portrayal of religious belief as a conceptual orientation to the world.
Proteomic analysis of rod photoreceptor outer segment and characterization of an aminophospholipid transporter-like ATPase
Creators: name: Kwok, Michael Chung Ming.
Publisher: name: University of British Columbia
Year: 2011

description: The photoreceptor outer segment is a specialized compartment of rod and cone photoreceptor cells which functions in vertebrate phototransduction, the process which converts light into electrical signals as the initial step in vision. Although the molecular mechanisms underlying phototransduction and light adaptation have been well examined, other cellular and molecular processes in the photoreceptor outer segment are not clearly understood. These include the mechanism of outer segment renewal, in particular the morphogenesis and shedding of disk membranes at opposite ends of the outer segment. In this study, a mass spectrometry-based proteomic approach was used to identify the complete proteome of the rod photoreceptor outer segment. Rod outer segments were isolated from bovine retina and separated into different subcellular preparations, followed by analysis on a tandem mass spectrometer. A total of 529 proteins were identified, including a large number of proteins that have not been previously reported to be present in the outer segments including a subset of proteins implicated in vesicle trafficking and membrane fusion. Using western blotting and immunofluorescence techniques, it was confirmed that the small GTPase Rab 11 and the Rab accessory protein Rab-GDI, as well as the SNARE protein VAMP 2/3 and SNARE-associated protein Munc 18-1 are true components of the rod outer segment. In addition, several uncharacterized proteins were identified one of which is aminophospholipid transporter-like ATPase IB (ATP8A2). The gene was cloned, expressed in cultured cells, and immunoaffinity purified. ATPase activity assay using radiolabeled [α-³²P] ATP showed that the purified protein was highly activated in the presence of brain polar lipid extract. Immunocytochemical studies showed a colocalization of the expressed protein with the ER-resident protein calnexin when expressed in HEK293 cells. These results, along with the proteomic data suggest that ATPase IB is a membrane protein in the rod outer segment that may play a role in transporting aminophospholipid across the membrane bilayer using ATP as an energy source. This study serves as a basis for understanding the role of this previously uncharacterized protein in the rod photoreceptor and determining whether mutations in the ATP8A2 gene may cause retinal disorders.

description: We prove that every place $P$ of an algebraic function field $F|K$ of arbitrary characteristic admits local uniformization, provided that the sum of the rational rank of its value group and the transcendence degree of its residue field $FP$ over $K$ is equal to the transcendence degree of $F|K$, and the extension $FP|K$ is separable. We generalize this result to the case where $P$ dominates a regular local Nagata ring $R\subseteq K$ of Krull dimension $\dim R\leq 2$, assuming that the valued field $(K,v_P)$ is defectless, the factor group $v_P F/v_P K$ is torsion-free and the extension of residue fields $FP|KP$ is separable. The results also include a form of monomialization. Further, we show that in both cases, finitely many Abhyankar places admit simultaneous local uniformization on an affine scheme if they have value groups isomorphic over $v_P K$.

description: In video streaming services, predicting the continuous user's quality of experience (QoE) plays a crucial role in delivering high quality streaming contents to the user. However, the complexity caused by the temporal dependencies in QoE data and the non-linear relationships among QoE influence factors has introduced challenges to continuous QoE prediction. To deal with that, existing studies have utilized the Long Short-Term Memory model (LSTM) to effectively capture such complex dependencies, resulting in excellent QoE prediction accuracy. However, the high computational complexity of LSTM, caused by the sequential processing characteristic in its architecture, raises a serious question about its performance on devices with limited computational power. Meanwhile, Temporal Convolutional Network (TCN), a variation of convolutional neural networks, has recently been proposed for sequence modeling tasks (e.g., speech enhancement), providing a superior prediction performance over baseline methods including LSTM in terms of prediction accuracy and computational complexity. Being inspired of that, in this paper, an improved TCN-based model, namely CNN-QoE, is proposed for continuously predicting the QoE, which poses characteristics of sequential data. The proposed model leverages the advantages of TCN to overcome the computational complexity drawbacks of LSTM-based QoE models, while at the same time introducing the improvements to its architecture to improve QoE prediction accuracy. Based on a comprehensive evaluation, we demonstrate that the proposed CNN-QoE model can reach the state-of-the-art performance on both personal computers and mobile devices, outperforming the existing approaches.

title: Narratives on the course of schizophrenia : client and family reflections on process and the impact on self
Creators: name: Barker, Sarah C.

description: A qualitative methodology was employed to explore the narratives of clients with a diagnosis of schizophrenia. These were used to obtain a subjective perspective on the course of schizophrenia and its impact on a person's sense of self Narratives from a nominated relative provided an alternative perspective on this process and thus served to increase the validity of the findings. Research questions specifically addressed the process of making sense of the experiences over time and the role of professionals within this, the impact on sense of self and the impact on relationships with others. Semi-structured inter-views were conducted with 16 participants. These were audiotaped, transcribed then grounded theory was used to analyse the data. Results were used to build a stage model which charts the process over time. It is tentatively hypothesised that earlier vulnerabilities in the formation of self are expressed during adolescence due to the developmental need to separate from parents and develop an adult identity. Implications for clinical work and services are discussed.

description: As Public Transport (PT) becomes more dynamic and demand-responsive, it increasingly depends on predictions of transport demand. But how accurate need such predictions be for effective PT operation? We address this question through an experimental case study of PT trips in Metropolitan Copenhagen, Denmark, which we conduct independently of any specific prediction models. First, we simulate errors in demand prediction through unbiased noise distributions that vary considerably in shape. Using the noisy predictions, we then simulate and optimize demand-responsive PT fleets via a linear programming formulation and measure their performance. Our results suggest that the optimized performance is mainly affected by the skew of the noise distribution and the presence of infrequently large prediction errors. In particular, the optimized performance can improve under non-Gaussian vs. Gaussian noise. We also find that dynamic routing could reduce trip time by at least 23% vs. static routing. This reduction is estimated at 809,000 EUR/year in terms of Value of Travel Time Savings for the case study.

Neue Möglichkeiten interaktiver 3-dimensionaler Modellierungen von Potentialfeldern und ihrer Ableitungen

description: Die hier dargestellten Methoden dienen der drei-dimensionalen, interaktiven Bearbeitung der Potentialfelder Gravimetrie und Magnetik, sowie ihrer Ableitungen (Schwere- und Magnetik-Tensor). Die Methodik ist sowohl für terrestrische, als auch Bohrloch- und Airborne-Verfahren einsetzbar. Um die Mehrdeutigkeit der interaktiven Bearbeitung bei der Vorwärtsrechnung und Inversion der Felder zu minimieren, beziehen die numerischen Verfahren verstärkt eine schnelle Computergraphik ein, sodass die Randbedingungen (meist aus der Reflexionsseismik) für die Berechnungen durch den Anwender stets sichtbar sind. Die Vorwärtsrechnungen basieren auf der Approximation geologischer Strukturen durch Polyeder, die Inversionsrechnungen für Geometrie und Gesteinsparameter (Dichte, remanente und induzierte Gesteinsmagnetisierung) werden mit Hilfe der CMA-ES (covariance-matrix-adoption evolution strategy) durchgeführt. CMA-ES ist die ideale Methode, um stark nicht-lineare und komplexe Probleme der Geophysik zu optimieren. Der Benutzer hat die Möglichkeit, die Inversion visuell zu steuern und zu beeinflussen. Die die Untergrundstrukturen approximierenden Polyeder sind durch konstante Gesteinsparameter charakterisiert; durch die Überlagerung eines Voxelmodells sind auch Strukturen mit hochgradig variabler Gesteinsparameterverteilung darstellbar. In vielen Anwendungen liegen häufig Daten vor, deren Auflösung für eine Potentialfelder-Modellierung nicht unbedingt erforderlich ist: Hier helfen neu entwickelte automatisierte Verfahren der gestalt-erhaltenden Datenreduktion. Für die Visualisierung von Potentialfeldern in Bohrlöchern werden Beispiele für eine nutzerfreundliche Visualisierung gezeigt.

description: Chemical reactions in multidimensional systems are often described by a rank-1 saddle, whose stable and unstable manifolds intersect in the normally hyperbolic invariant manifold (NHIM). Trajectories started on the NHIM in principle never leave this manifold when propagated forward or backward in time. However, the numerical investigation of the dynamics on the NHIM is difficult because of the instability of the motion. We apply a neural network to describe time-dependent NHIMs and use this network to stabilize the motion on the NHIM for a periodically driven model system with two degrees of freedom. The method allows us to analyze the dynamics on the NHIM via Poincaré surfaces of section (PSOS) and to determine the transition state (TS) trajectory as a periodic orbit with the same periodicity as the driving saddle, viz. a fixed point of the PSOS surrounded by near-integrable tori. Based on Transition State Theory and a Floquet analysis of a periodic TS trajectory we compute the rate constant of the reaction with significantly reduced numerical effort compared to the propagation of a large trajectory ensemble.
