Initiation of illicit drugs among youth : determinants and responses
Creators: name: Werb, Daniel
Publisher: name: University of British Columbia
Year: 2010

description: Background: Many youth initiate illicit drugs at a high level. Further, despite the application of preventive interventions to reduce this phenomenon and related harms, there is little evidence that current efforts to prevent illicit drug use and problematic drug use are effective. This research project was therefore undertaken to investigate determinants of, and popular responses to, the initiation of illicit drug use among youth. Methods: Meta-analytic techniques were used to quantify the evidence on the effectiveness of anti-illicit drug public service announcements. Further, data from the At-Risk Youth Study (ARYS), a prospective cohort of homeless and street-involved youth between the ages of 14 and 26, were analyzed using linear regression analysis to determine factors associated with residing in Vancouver’s downtown eastside (DTES), the location of a large open air illicit drug market, and in the downtown south (DTS), an adjacent neighbourhood. Specifically, between September 2005 and December 2007, participants completed a baseline questionnaire which elicted information on income sources, drug use behaviours, sexual behaviours, and the initiation of illicit drugs. Results: We identified 7 randomized trials (n = 5,428) and 4 observational trials (n = 17,404). A meta-analysis of eligible randomized trials demonstrated no significant effect, while observational studies showed evidence of both harmful and beneficial effects. Further, among 222 youth participants, having a primary illicit income source and injection heroin use were significantly associated with residing in the DTES in multivariate analysis. No significant differences in risk of drug trade and sex trade involvement, crack use, injection cocaine use, and injection crystal methamphetamine use were found between youth residing in each neighbourhood. Conclusions: Our findings suggest that current approaches to the prevention of the initiation of illicit drug use among youth may be limited. Further, the results of our linear regression analysis suggest that a consideration of social and structural factors may increase the effectiveness of current preventive interventions. As such, policymakers should consider reorienting current approaches to illicit drug prevention among youth.
Biochemical Studies of Terpenoid Metabolism in Aztec Sweet Herb
Creators: name: Hurd, Matthew

Subjects: Botany

description: Analysis of ethnobotanical literature led scientists to discover the Aztec sweet herb (Lippia dulcis), a highly aromatic plant containing the potent sesquiterpene ketone sweetener, hernandulcin. Despite the intense sweetness of L. dulcis, the main volatile constituent is the bitter-tasting and toxic monoterpenoid, camphor. To date, the biosynthesis of hernandulcin and camphor have yet to be fully elucidated in L. dulcis. Identification of key genes involved in both pathways could be used to enhance the safety and quality of hernandulcin-based alternative sweetener product. Two terpene synthases (TPSs) were identified from L. dulcis transcriptomics, one of which exhibited bornyl diphosphate synthase (LdBPPS) activity, catalyzing the first step of camphor biosynthesis in L. dulcis. Interestingly, the N-terminal region of LdBPPS contains a duplicated RRX8W motif that was found to be inhibitory in vitro, suggesting that it may be cleaved with the chloroplast transit peptide. Phylogenetic analysis demonstrated that LdBPPS evolved independently from the homologous enzyme in sage, despite both performing the same biochemical reaction. A cytochrome P450 monooxygenase (P450) was hypothesized to convert (+)-epi-α-bisabolol to hernandulcin. The induction of hernandulcin biosynthesis by methyl jasmonate was investigated to generate an elicitor-based transcriptome library but was found to be ineffective. Therefore, a homology-based cloning was used to identify ten putative P450s and their expression and activity were tested in yeast. A total of seven P450s were expressed in yeast, determined by immunoblot analyses, in either the native form or after N-terminal replacement. Six P450s showed no unique product formation after GC-MS analysis while one P450 (LdO10) showed minor affinity to (+)-epi-α-bisabolol substrate and produced bisabolol oxide B. Future efforts should be used to generate better bioinformatic resources to facilitate the mining for genes involved in hernandulcin biosynthesis.

description: While research on factors contributing to the success of a reward-based crowdfunding project is abundant, research dedicated to projects that were not only successful, but received significantly more funds than initially targeted—overfunded projects—is still scarce. Following a qualitative case-study approach, this study sought to shed light on this phenomenon through examining expert interviews with supporters and team members of an overfunded crowdfunding project considered a critical case. The results are divided into three phases that differentiate characteristics ascribed to the crowd, the project, and the communication. The main findings highlight the central role of the project founders’ reputation and experience, that a positive sentiment among the crowd towards the project must be encouraged and maintained and that the core target group must be correctly identified and attracted. This core target group is crucial for attracting a broader audience, a mechanism that is supported if the project benefits from network effects. A narrative of the project as a vision or ‘dream’ of the project founders thereby contributes to creating a hype and ‘social buzz’. Ultimately, this study contributes to reward-based crowdfunding literature through offering novel insights on project overfunding and illustrating possibilities for new and small ventures how to attract and maintain customers through reward-based crowdfunding.

description: The primary goal of this study has been to develop the mixed ion-electron conductors (MIECs) to illustrate their potential applications for real-time detection of CO2 and SO2 in ppm level. For this purpose, B-site substituted ordered perovskite-type MIECs Ba2(Ca0.66Nb1.34-xFex)O6-δ (x = 0, 0.34, 0.66, 1) (BCNF) and B-site disordered MIECs Ba(Mg0.33Nb0.67-xFex)O3-δ (x = 0, 0.17, 0.33, 0.50) (BMNF) were successfully synthesized by conventional solid state method in air at 1400 °C. Fe-substitution in BCNFs and BMNFs increased the total conductivity, while in-situ high temperature (25–800 °C) PXRD results under CO2 exhibited excellent chemical stability. The resistance of the MIEC ceramics significantly decreased upon exposure to CO2 gas in synthetic air. Response time (t90) of 4 min at 700 °C was obtained with higher Fe-content samples with thickness of 2 mm and diameter of 10 mm. To develop a fundamental understanding of the sensing mechanism, Fe-doped BCNFs were investigated. Firstly, p-type bulk semiconducting nature of BCNF was explored using AC impedance spectroscope and DC measurements using different p(CO2) and p(O2). Secondly, BCNFs were further studied using SEM coupled with EDX, 57Fe Mössbauer spectroscopy, Raman spectroscopy, TPO-MS. Upon CO2 exposure, CO2 was found to be catalytically reduced to C and can be explained using oxidation of Fe3+ to Fe4+/ Fe5+. Thus, the increase in total conductivity upon CO2 exposure is interpreted by the deposition of conducting graphitic C, which was confirmed using Raman spectra and TPO-MS. Furthermore; SEM/EDX results displayed the deposited C due to the reduction of CO2. For SO2 sensors, SnO2-TiO2 (S-T) composites with different molar ratios were also prepared at 700 °C in air to selectively monitor ppm level of SO2 in air. For S-T composites, the chemical stability were tested using PXRD, SEM and EDX, while the sensing performance was measured at different temperatures using various concentrations of SO2 (10-100 ppm). The highest sensitivity was obtained from a mixture of 25 mol.% of SnO2 and 75 mol.% ofTiO2 at 450 °C with t90 of ~5 mins. S-T composite sensors behave as a resistive-type SO2 sensor and sensing mechanism has been explained through the band structure model.

description: Multimodal conversational interfaces provide a natural means for users to communicate with computer systems through multiple modalities such as speech and gesture. To build effective multimodal interfaces, automated interpretation of user multimodal inputs is important. Inspired by the previous investigation on cognitive status in multimodal human machine interaction, we have developed a greedy algorithm for interpreting user referring expressions (i.e., multimodal reference resolution). This algorithm incorporates the cognitive principles of Conversational Implicature and Givenness Hierarchy and applies constraints from various sources (e.g., temporal, semantic, and contextual) to resolve references. Our empirical results have shown the advantage of this algorithm in efficiently resolving a variety of user references. Because of its simplicity and generality, this approach has the potential to improve the robustness of multimodal input interpretation.

Distribution. Finland, *Russian Fennoscandia.—Westpalearctic: not known outside eastern Fennoscandia.
Remarks. The species is very rare and only known from three coastal localities in Finland (N: Hanko, Om: Kokkola, Oba: Oulu) and two localities in Russian Fennoscandia. In Finland, it is classified as critically endangered (Paukkunen 2010). The species was erroneously synonymized with H. fervida by Trautmann (1927) and Linsenmaier (1951, 1959). However, Linsenmaier (1987) later reinstated it as a valid species.
Dahlbom (1854) described the species as Hedychrum metallicum on the basis of one specimen collected by W. Nylander from Finland in 27.VII.1844. The holotype is a small male, and it is deposited in MZH in Helsinki (Fig. 2). It has the original labels “Uleåborg” (= Oulu), “d. 27/7 44”, “ Coll. Nylander ”, “n. sp.?” and “256.”. Type labels have been added later, including the holotype label.

description: The developments of liquid crystalline porphyrins are of interest to chemists in the field of applied chemistry and material science due to their potential as functional organic materials. This pursuit involved synthesizing 5, 10, 15, 20- meso-tetrakis(3,5- or 4-alkoxyphenyl)ethynylporphyrins. Incorporating an ethynyl linker at the meso-positions first involved the preparation of 3-(3,5- or 4-alkoxyphenyl)propynals, then subjecting them to porphyrin syntheses under Lindsey’s conditions. Good overall yields of 3-(4-alkoxyphenyl)propynals were achieved by optimization at each synthetic step: alkylation, Sonogashira cross – coupling reaction combined with desilylation, and formylation. Adjusted Sonogashira reaction conditions and a optimized co-catalyst ratio of 0.05: 0.03 molar equivalence of palladium(0) and copper(I) catalyst respectively, 100% conversion according to 1H NMR spectroscopy was achieved and yields nearing 80% was calculated after desilylation. The successful preparation of 3-(4-alkoxyphenyl)propynals and not 3-(3,5-alkoxyphenyl)propynals with a high yield of 85% was achieved. However, further optimization of meso-tetrakis(4-alkoxyphenyl)ethynylporphyrin reactions involving cobalt carbonyl protected 3-(4-alkoxyphenyl)propynal needs to be accomplished.

description: Density Functional Theory (DFT) calculations using CAM-B3LYP hybrid functional were performed on the binary and ternary van der Waals complexes formed from CS2 and C2D2 monomers. Theoretical stationary structures were found. The geometrical parameters of stationary structures were optimized and their theoretical rotational constants were obtained. The calculations predict a planar parallel configuration with C2v symmetry as the lowest energy isomer of CS2-C2D2 dimer. These calculations also show that a T-shaped structure with C2v symmetry is the higher energy isomer. They also indicate that a twisted-barrel configuration with C2 symmetry is the minimum energy isomer of (CS2)2-C2D2 mixed trimer. In addition, the two minimum energy isomers of CS2-(C2D2)2 trimer were found. The global minimum structure has a distorted T-shaped C2D2 dimer unit with a CS2 monomer “above” the dimer and the higher energy isomer has a planar configuration. In agreement with the DFT calculations, rotationally-resolved infrared spectra of the parallel isomer of CS2-C2D2 and the twisted barrel shaped isomer of (CS2)2-C2D2 trimer were observed and simulated in the region of C2D2 v3 (~2439 cm-1) stretching fundamental. The complexes were generated in a supersonic slit-jet apparatus and probed using an Optical Parametric Oscillator (OPO). The observed band of CS2-C2D2 dimer is centered at 2438.16 cm-1 whereas the band for the (CS2)2-C2D2 trimer is centered at 2436.73 cm-1. Both bands indicate red shifts with respect to C2D2 v3 fundamental band origin (2439.244 cm-1). The observed rotational constants are in good agreement with those obtained from the DFT calculations

description: The intermediate- to high-mass star-forming region IRAS 20343+4129 is an excellent laboratory to study the influence of high- and intermediate-mass young stellar objects on nearby starless dense cores, and investigate for possible implications in the clustered star formation process. We present 3 mm observations of continuum and rotational transitions of several molecular species (C2H, c-C3H2, N2H+, NH2D) obtained with the Combined Array for Research in Millimetre-wave Astronomy, as well as 1.3 cm continuum and NH3 observations carried out with the Very Large Array, to reveal the properties of the dense gas. We confirm undoubtedly previous claims of an expanding cavity created by an ultracompact HII region associated with a young B2 zero-age main sequence (ZAMS) star. The dense gas surrounding the cavity is distributed in a filament that seems squeezed in between the cavity and a collimated outflow associated with an intermediate-mass protostar. We have identified 5 millimeter continuum condensations in the filament. All of them show column densities consistent with potentially being the birthplace of intermediate- to high-mass objects. These cores appear different from those observed in low-mass clustered environments in sereval observational aspects (kinematics, temperature, chemical gradients), indicating a strong influence of the most massive and evolved members of the protocluster. We suggest a possible scenario in which the B2 ZAMS star driving the cavity has compressed the surrounding gas, perturbed its properties and induced the star formation in its immediate surroundings.

description: Epilepsy is the second most common neurological condition and can be associated with significant morbidity, premature mortality, and high resource use. Epilepsy is a spectrum disorder due its diverse presentation, making it challenging to manage. As a result, treatment gaps exist. Clinical practice guidelines should facilitate the care of people with epilepsy. While evidence exists that guidelines are effective in improving the quality of care in some clinical settings, this has not been demonstrated for epilepsy. The objectives of this thesis are to: 1) Identify gaps in epilepsy guidelines, 2) Determine barriers and facilitators to implementation of epilepsy guidelines, and 3) Develop a knowledge translation (KT) strategy to optimize dissemination and implementation of epilepsy guidelines. Several methods were used to achieve the study objectives. A systematic review of epilepsy guidelines was conducted to identify gaps. A mixed-methods approach (quantitative survey and focus groups) was used to identify the determinants of guideline use among neurologists. Based on the results of the study examining determinants of guideline use, a theory-based KT strategy was proposed to facilitate future implementation of epilepsy guidelines in clinical practice. The systematic review identified 63 guidelines for the care of epilepsy covering 19 populations/conditions. Gaps in the availability of guidelines for high priority areas (i.e. elderly) and significant heterogeneity in quality were identified. Despite the number of guidelines available for the care of people with epilepsy, use of these guidelines clinically is poor. Reasons for the poor implementation of these guidelines among neurologists (end-users of epilepsy guidelines) were identified here, and include: lack of knowledge, poor credibility, applicability and motivation, insufficient resources, and lack of clarity regarding the target users. A three-pillared KT strategy to overcome the barriers of guideline use, and leverage facilitators is proposed to improve implementation in clinical practice. This body of work provides novel evidence into the current state of epilepsy guidelines, and the factors that determine their use clinically. This novel insight helps bridge a knowledge gap while the KT strategy outlined here provides the tools required to move towards improving implementation of guidelines for the care of people with epilepsy internationally.

description: Electrical conductivity of FeO was measured up to 141 GPa and 2480 K in a laserheated diamond-anvil cell. The results show that rock-salt (B1) type structured FeO metallizes at around 70 GPa and 1900 K without any structural phase transition. We computed fully self-consistently the electronic structure and the electrical conductivity of B1 FeO as a function of pressure and temperature, and found that although insulating as expected at ambient condition, B1 FeO metallizes at high temperatures, consistent with experiments. The observed metallization is related to spin crossover.

description: Indoor navigation is now used in many applications. For enhanced positioning accuracy indoors, this thesis develops the strategies and algorithms for multiple navigational integration modes coupled with multi-sensors fusion in smartphones. The sensors consist of an INS-magnetometer triad and a pressure sensor, in addition to WiFi signals. The main focus is to make full use of the complementary features of different sensors and different navigation modes to improve accuracy. One of the sensors, namely pressure sensor, complements the limitations of PDR and WiFi by extending the position dimension from 2D to 3D. A centralized Kalman filter is designed and implemented for the proposed integration strategies including PDR and INS, WiFi and INS, as well as combination of PDR, WiFi and INS. Extensive indoor tests conducted in various buildings are used to evaluate the above strategies. Related navigation performance metrics are evaluated and inter-compared and their error statistics are summarized.

description: This study investigates explanations behind the rise of Homegrown Islamic Terrorism (HIT) in India. It questions the externalizing discourse of the security literature and locates reasons for HIT in domestic political events, guided by a Critical Terrorism Studies approach. To explore the emergence of HIT, this study focuses on a parallel trend in Indian politics- the rise of right-wing Hindu nationalism or the Hindutva movement and its targeting of the Muslim minority. The research question guiding this study is: How can the emergence of homegrown Islamic terrorism in India be explained as a consequence of political Hindutva? Using the methodology of process-tracing, this study establishes a positive relationship between Hindutva and HIT, operationalized through a mechanism of communal politics and Hindu-Muslim riots.
Generalized Schrieffer-Wolff Formalism for Dissipative Systems

description: We present a formalized perturbation theory for Markovian open systems in the language of a generalized Schrieffer-Wolff (SW) transformation. A non-unitary rotation decouples the unper- turbed steady states from all fast degrees of freedom, in order to obtain an effective Liouvillian, that reproduces the exact low excitation spectrum of the system. The transformation is derived in a constructive way, yielding a perturbative expansion of the effective Liouville operator. The presented formalism realizes an adiabatic elimination of fast degrees of freedom to arbitrary orders in the perturbation. We exemplarily employ the SW formalism to two generic open systems and discuss general properties of the different orders of the perturbation.

description: In recent years the Federal Reserve has set very low policy interest rates in response to the global financial crisis and Great Recession. But as the federal funds rate has become almost constant since the first quarter of 2009, it partially has lost its appeal to affect the major macroeconomic and financial indicators. In this backdrop, an interesting question is whether leverage of financial institutions can play a role in business cycle analysis and forecasting the economy through the leverage‒asset price‒output relationship. In Essay 1 (Chapter 2), I investigate whether the relationship between leverage and real GDP is nonlinear and asymmetric, using slope-based tests as well as tests of the null hypothesis of symmetric impulse responses. I find that in general the relationship between leverage and real GDP is nonlinear and asymmetric, meaning that when leverage declines the effect is much more stronger on real GDP compared to when leverage increases. In Essay 2 (Chapter 3), I explore the effects of broker-dealer leverage on the economy and the interdependence between monetary policy and broker-dealer leverage in the context of a structural vector autoregression model. I apply short-run and long-run restrictions based on economic theory to identify monetary policy and leverage shocks. I also use the sign restrictions approach to the identification of a leverage demand shock and examine its effect on the economy. My results show that broker-dealer leverage demand shocks can influence monetary policy decisions and also can affect key macroeconomic indicators. In Essay 3 (Chapter 4), I investigate whether the macroeconomic effects of broker-dealer leverage and the interdependence between monetary policy and broker-dealer leverage vary over time, by using a time-varying parameter vector autoregression model. I find that the procyclical nature of broker-dealer leverage has become evident since the year 2000. Based on my finding that leverage and economic activity move in the same direction in recent times, I conclude that regulation of leverage under the Basel III regulation is not promising for the economy. I suggest countercyclical capital requirements, which works as a supportive tool for the current apparently easy monetary policy in the United States.

description: The main focus and contribution of this paper is a novel network-MIMO TDD architecture that achieves spectral efficiencies comparable with "Massive MIMO", with one order of magnitude fewer antennas per active user per cell. The proposed architecture is based on a family of network-MIMO schemes defined by small clusters of cooperating base stations, zero-forcing multiuser MIMO precoding with suitable inter-cluster interference constraints, uplink pilot signals reuse across cells, and frequency reuse. The key idea consists of partitioning the users population into geographically determined "bins", such that all users in the same bin are statistically equivalent, and use the optimal network-MIMO architecture in the family for each bin. A scheduler takes care of serving the different bins on the time-frequency slots, in order to maximize a desired network utility function that captures some desired notion of fairness. This results in a mixed-mode network-MIMO architecture, where different schemes, each of which is optimized for the served user bin, are multiplexed in time-frequency. In order to carry out the performance analysis and the optimization of the proposed architecture in a clean and computationally efficient way, we consider the large-system regime where the number of users, the number of antennas, and the channel coherence block length go to infinity with fixed ratios. The performance predicted by the large-system asymptotic analysis matches very well the finite-dimensional simulations. Overall, the system spectral efficiency obtained by the proposed architecture is similar to that achieved by "Massive MIMO", with a 10-fold reduction in the number of antennas at the base stations (roughly, from 500 to 50 antennas).

Previous spatial concentration detection methods did not consider the severity levels of accidents, and the final traffic accident risk map for the whole study area ignores the different users’ requirements. This thesis proposes an ontology-based traffic accident risk mapping framework. In the framework, the ontology represents the domain knowledge related to the traffic accidents and supports the data retrieval based on users' requirements. A new spatial clustering method, called DBCTAR (Density-based Clustering for Traffic Accident Risk), takes into account the numbers and severity levels of accidents is proposed for risk mapping. To demonstrate the framework and the new algorithm, the Ontology-based Traffic Accident Risk Mapping (ONTO_TARM) system and a web-based clustering service GeoClustering have been developed. Four case studies in the city of Calgary with final risk maps are presented and discussed.

description: Der Name des ersten Direktors der 1926 begründeten Verwaltung der Staatlichen Schlösser und Gärten – der Vorläuferinstitution der heutigen Stiftung Preußische Schlösser und Gärten Berlin-Brandenburg – ist kaum noch jemandem geläufig. Dabei war die Karriere des Kunsthistorikers Paul Gustav Hübner vielversprechend: Er hatte bei Adolph Goldschmidt (1863–1944) promoviert, arbeitete als Assistent in der Bibliothek Aby Warburgs (1866–1929) in Hamburg und an der Bibliotheca Hertziana in Rom. Nach dem Ersten Weltkrieg wurde er vom preußischen Finanzministerium zu den Liegenschaften der abgedankten Hohenzollern geschickt, um diese zu inventarisieren. Aus dieser Tätigkeit entwickelte sich seine Idee des Umgangs der Öffentlichkeit mit den Schlössern und Gärten, die er auch öffentlich vertrat. 1933 wurde er unter Berufung auf das „Gesetz zur Wiederherstellung des Berufsbeamtentums“ in den vorzeitigen Ruhestand versetzt und nach seinem Tod 1941 von der Nachwelt vergessen. Dieser Beitrag soll Paul Gustav Hübner als Akteur wieder bekannt machen und Forschungsansätze aufzeigen.

description: Disordered eating is on the rise and our current conceptualization and treatment of such problems neglects a corporeal-relational understanding in favour of a more cognitive approach. In this hermeneutic phenomenological study, I explore the experiences of fourteen women with eating disorders who took part in an Equine-Facilitated Counselling group. The participants engaged in group and individual interviews that helped to articulate a language for understanding their bodily-relational experiences. Through dialogic movement and communication with their horses, the participants were able to attune in different ways to themselves and their worlds, thus interrupting some of the habitual practices of disordered eating. These changes in attunement occurred during moments of communion with their horses, but also had an influence afterwards, in a variety of ways that led to the creation of preferred ways of being and relating for a number of the participants. These changes and the moments that made a difference are explored through stories pertaining to five of the women and their horses. Implications for counselling theory, practice, and possible future research are discussed.

description: Models for the progenitor systems of Type Ia supernovae can be divided into double-degenerate systems, which contain two white dwarfs, and single-degenerate systems, which contain one white dwarf plus one companion star (either a red giant, a subgiant, or a >1.16 M_sol main sequence star). The white dwarf is destroyed in the supernova explosion, but any non-degenerate companion remains intact. We present the results of a search for an ex-companion star in SNR 0519-69.0, located in the Large Magellanic Cloud, based on images taken with the Hubble Space Telescope with a limiting magnitude of V = 26.05. SNR 0519-69.0 is confidently known to be from a Type Ia supernova based on its light echoes and X-ray spectra. The geometric center of the remnant (based on the H-alpha and X-ray shell) is at 05:19:34.83, -69:02:06.92 (J2000). Accounting for the measurement uncertainties, the orbital velocity, and the kick velocity, any ex-companion star must be within 4.7" of this position at the 99.73% confidence level. This circle contains 27 main sequence stars brighter than V = 22.7, any one of which could be the ex-companion star left over from a supersoft source progenitor system. The circle contains no post-main sequence stars, and this rules out the possibility of all other published single-degenerate progenitor classes (including symbiotic stars, recurrent novae, helium donors, and the spin-up/spin-down models) for this particular supernova. The only remaining possibility is that SNR 0519-69.0 was formed from either a supersoft source or a double-degenerate progenitor system.

description: We present an updated version of SKIRT, a 3D Monte Carlo radiative transfer code developed to simulate dusty galaxies. The main novel characteristics of the SKIRT code are the use of a stellar foam to generate random positions, an efficient combination of eternal forced scattering and continuous absorption, and a new library approach that links the radiative transfer code to the DustEM dust emission library. This approach enables a fast, accurate and self-consistent calculation of the dust emission of arbitrary mixtures of transiently heated dust grains and polycyclic aromatic hydrocarbons, even for full 3D models containing millions of dust cells. We have demonstrated the accuracy of the SKIRT code through a set of simulations based on the edge-on spiral galaxy UGC 4754. The models we ran were gradually refined from a smooth, 2D, LTE model to a fully 3D model that includes NLTE dust emission and a clumpy structure of the dusty ISM. We find that clumpy models absorb UV and optical radiation less efficiently than smooth models with the same amount of dust, and that the dust in clumpy models is on average both cooler and less luminous. Our simulations demonstrate that, given the appropriate use of optimization techniques, it is possible to efficiently and accurately run Monte Carlo radiative transfer simulations of arbitrary 3D structures of several million dust cells, including a full calculation of the NLTE emission by arbitrary dust mixtures.

description: With the advances in computational technologies over the last decade, large organizations have been investing in Information Technology to automate their internal processes to cut costs and efficiently support their business projects. However, this comes to a price. Business requirements always change. Likewise, IT systems constantly evolves as developers make new versions of them, which require endless administrative manual work to customize and configure them, especially if they are being used in different contexts, by different types of users, and for different requirements. Autonomic computing was conceived to provide an answer to these ever-changing requirements. Essentially, autonomic systems are self-configuring, self-healing, self-optimizing, and self-protecting; hence, they can automate all complex IT processes without human intervention. This paper proposes an autonomic model based on Venn diagram and set theory for self-configuring C#.NET applications, namely the self-customization of their GUI, event-handlers, and security permissions. The proposed model does not require altering the source-code of the original application; rather, it uses an XML-based customization file to turn on and off the internal attributes of the application. Experiments conducted on the proposed model, showed a successful automatic customization for C# applications and an effective self-adaption based on dynamic business requirements. As future work, other programming languages such as Java and C++ are to be supported, in addition to other operating systems such as Linux and Mac so as to provide a standard platform-independent autonomic self-configuring model.

description: There is a debate in the literature on free will and responsibility regarding whether responsibility is historical. The focus is on what makes one’s values, desires, beliefs, and other springs of action authentic or “truly one’s own”, and what effect, if any, past manipulation has on authenticity. In this thesis, I present and attempt to clarify fundamental concepts, and give a critical account of prominent theories and motivating cases. I propose constraints on theories of responsibility, including a generalized regress problem affecting “positive” historical theories, and argue for a characterization of springs on which springs of the same type are treated as identical. I conclude by presenting a sketch of a historical theory of responsibility which conforms to my proposed constraints.

description: Tree visualization is a branch of information visualization dedicated to visualizing hierarchy within a dataset. It has widespread applications in visualizing Ancestry, the File System, an Organizational Chart, Internet Addressing, and many more. To adequately represent a particular hierarchical dataset, customization of existing tree layouts or even building a novel tree layout is necessary. A review of the existing information visualization toolkits shows their limitations in providing layout customization and task-specific interaction support for trees. Using the existing toolkits, developers often are required to write code from scratch to implement/customize a tree layout if it is not supported by the toolkit. This process requires significant effort from developers both in terms of coding and in understanding the domain. This thesis presents findings from usability studies of AVIT – an API for Visualizing and Interacting with Trees. AVIT has been developed with the main focus of providing ease of use to software developers in implementing and customizing different tree layouts with task-specific interaction support. To gather developers’ feedback, two usability evaluations of AVIT were conducted. The first evaluation identified usability problems in AVIT. Based on the feedback, changes were made to the API and the documentation to improve usability. A second evaluation was conducted on an updated version of AVIT to determine what impact the changes had on the usability experience of the API and identified additional usability issues for future iterations of development. Lessons learned from developing and evaluating AVIT are also discussed to aid future work in this area.

description: The set of all channels with fixed input and output is convex. We first give a convenient formulation of necessary and sufficient condition for a channel to be extreme point of this set in terms of complementary channel, a notion of big importance in quantum information theory. This formulation is based on the general approach to extremality of completely positive maps in an operator algebra due to Arveson. We then apply this formulation to prove the main result of this note: under certain nondegeneracy conditions, purity of the environment is necessary and sufficient for extremality of Bosonic linear (quasi-free) channel. It follows that Gaussian channel between finite-mode Bosonic systems is extreme if and only if it has minimal noise.
