description: The Drug and Violence Resistance Educational Program (Programa Educacional de Resistência às Drogas e à Violência – PROERD) is the most widely implemented prevention program in Brazil and this study evaluated the reasons and ways in which PROERD instructors change the program, affecting its implementation fidelity. This qualitative method study used three data sources: semi-structured interviews with 19 police officers (PROERD instructors), fidelity forms completed by the instructors, and the researcher’s observations of 30 lessons, followed by thematic analysis. Strong evidence shows that instructors adapt the program, in general, because they experienced that some activities do not work when implemented as they were created by the developers. The main reasons to adapt the program were categorized into two groups: intrinsic and extrinsic reasons. The cultural reality and school performance of students and the support and infrastructure of the school were the extrinsic reasons, and instructors’ performance was the intrinsic reason. In order to make PROERD feasible for students and schools, instructors change the program in an unstructured way, often not following the curriculum. Therefore, PROERD will hardly have a positive effect for Brazilian students.

description: We report on a technique enabling electrical control of the contact silicidation process in silicon nanowire devices. Undoped silicon nanowires were contacted by pairs of nickel electrodes and each contact was selectively silicided by means of the Joule effect. By a realtime monitoring of the nanowire electrical resistance during the contact silicidation process we were able to fabricate nickel-silicide/silicon/nickel- silicide devices with controlled silicon channel length down to 8 nm.

description: ‘How To Save A Life’ (HTSAL) was a mass media campaign on drug-related death prevention which ran in Scotland from August 2021 to January 2022. It aimed to increase awareness of how to respond to an opioid overdose, and the uptake of take-home naloxone (THN). The objective of this study was to determine the reach and engagement with the campaign. Methods included a descriptive analysis of data from media sources, the campaign website, and an online naloxone training course. A quantitative content analysis was conducted on media articles. The campaign generated 57,402,850 non-unique impressions (the total number of times the campaign was seen or heard), and unique reach (the number of people who were exposed to the campaign) figures of 2,621,450. Engagement with the campaign was positive, and 96% of print/digital media articles had a positive view of the campaign. There were 40,714 visits to the campaign website, leading to 8,107 clicks to the free naloxone training course, and 3,141 clicks to order a free naloxone kit. This study showed that mass media campaigns on drug policy topics can achieve high levels of reach and engagement. There was a clear progression from viewing campaign materials, to visiting the campaign website, to completing naloxone training. Our research suggests that mass media campaigns can be used to disseminate harm reduction messages to the general public.
Omnigenity as generalized quasisymmetry

Subjects: subject: Plasma Physics (physics.plasm-ph)
subject: FOS: Physical sciences

description: Any viable stellarator reactor will need to be nearly omnigenous, meaning the radial guiding-center drift velocity averages to zero over time for all particles. While omnigenity is easier to achieve than quasisymmetry, we show here that several properties of quasisymmetric plasmas also apply directly or with only minor modification to the larger class of omnigenous plasmas. For example, concise expressions exist for the flow and current, closely resembling those for a tokamak, and these expressions are explicit in that no magnetic differential equations remain. A helicity (M,N) can be defined for any omnigenous field, based on the topology by which |B| contours close on a flux surface, generalizing the helicity associated with quasisymmetric fields. For generalized quasi-poloidal symmetry (M=0), the bootstrap current vanishes, which may yield desirable equilibrium and stability properties. A concise expression is derived for the radial electric field in any omnigenous plasma that is not quasisymmetric. The fact that tokamak-like analytical calculations are possible in omnigenous plasmas despite their fully-3D magnetic spectrum makes these configurations useful for gaining insight and benchmarking codes. A construction is given to produce omnigenous B(theta, zeta) patterns with stellarator symmetry.

description: We continue the study of the low-energy limit of N=4 super Yang-Mills theory compactified on a circle with S-duality and R-symmetry twists that preserve N=6 supersymmetry in 2+1D. We introduce external static supersymmetric quark and anti-quark sources into the theory and calculate the Witten Index of the resulting Hilbert space of ground states on a torus. Using these results we compute the action of simple Wilson loops on the Hilbert space of ground states without sources. In some cases we find disagreement between our results for the Wilson loop eigenvalues and previous conjectures about a connection with Chern-Simons theory.

description: Metadata is one of the key elements in making data FAIR (Findable, Accessible, Interoperable and Reusable) but currently across the fusion community there is not a widely adopted standard which would allow easy cross site discovery of data of interest, largely due to the presence of long standing existing practices. This document presents a proposed metadata model to overcome this issue. This model has been built based on existing schemas previously designed to support the fusion community with the involvement of a wide range of stakeholders from across the European Fusion community. To support ‘open data’ and ease discovery for non community users we have also adopted some elements of Dublin Core Elements, which also allow us to some very basic provenance tracking of versions. A full provenance model will be incorporated in a later deliverable. While as a project we are not recommending sites change their existing practices of even adopt this schema, we propose to aggregate metadata from sites and convert it to this schema to allow for simpler cross site discovery and access, something which is currently impossible to do. In conclusion we find that the use of the Summary IDS which has been co-developed with the fusion community is suitable as a metadata schema for the community, providing a rich set of metadata, a few additions are required to better support the FAIR principles such as provision for a globally unique, actionable persistent identifier, suitable licensing information and provenance.

A regularization of the 4-sphere is also performed by constructing N^2 x N^2 matrix representations of the 4-algebra (and as a byproduct of the 3-algebra which makes the regularization of S^3 also possible).

Cupid's Invisible Hand: Social Surplus and Identification in Matching Models

Year: 2011
Subjects: Economics

description: We investigate a matching game with transferable utility when some of the characteristics of the players are unobservable to the analyst. We allow for a wide class of distributions of unobserved heterogeneity, subject only to a separability assumption that generalizes Choo and Siow (2006). We first show that the stable matching maximizes a social gain function that trades of two terms. The first term is simply the average surplus due to the observable characteristics; and the second one can be interpreted as a generalized entropy function that reflects the impact of the unobserved characteristics. We use this result to derive simple closed-form formulÃ¦ that identify the joint surplus in every possible match and the equilibrium utilities of all participants, given any known distribution of unobserved heterogeneity. Moreover, we show that if transfers are observed, then the pre-transfer utilities of both partners are also identified. We conclude by discussing some empirical approaches suggested by these results for the study of marriage markets, hedonic prices, and the market for CEOs.

description: Based on the principle of chaotification for continuous-time autonomous systems, which relies on two basic properties of chaos, i.e., globally bounded with necessary positive-zero-negative Lyapunov exponents, this paper derives a feasible and unified chaotification method of designing a general chaotic continuous-time autonomous nonlinear system. For a system consisting of a linear and a nonlinear subsystem, chaotification is achieved using separation of state variables, which decomposes the system into two open-loop subsystems interacting through mutual feedback resulting in an overall closed-loop nonlinear feedback system. Under the condition that the nonlinear feedback control output is uniformly bounded where the nonlinear function is of bounded-input/bounded-output, it is proved that the resulting system is chaotic in the sense of being globally bounded with a required placement of Lyapunov exponents. Several numerical examples are given to verify the effectiveness of the theoretical design. Since linear systems are special cases of nonlinear systems, the new method is also applicable to linear systems in general.

description: Nonpolynomial basic hypergeometric eigenfunctions of the Askey-Wilson second order difference operator are known to be expressible as very-well-poised 8phi7 series. In this paper we use this fact to derive various basic hypergeometric and theta function identities. We relate most of them to identities from the existing literature on basic hypergeometric series. This leads for example to a new derivation of a known quadratic transformation formula for very-well-poised 8phi7 series. We also provide a link to Chalykh's theory on (rank one, BC type) Baker-Akhiezer functions.

description: How do we talk about race? This discourse often falls in the political and activist spheres, however, it has been ineffective in connecting the masses, so we must find a way to communicate with people who are “tired of hearing about race.” We must also find a way to stay whole in this political climate. Art has the ability of doing both. Our stories have the ability of doing both. This document explores the journey that I have taken in my discovery of my voice in the theatre that began with attempting to appeal to the people who are tired of hearing about race and ended with creating a performance that speaks to those who are not spoken to in the theatre. The first two chapters of this thesis document the foundational work needed in order to successfully complete this thesis project. Chapters 2 and 3 explore my newfound voice. The fifth chapter documents the creation and performance of my pre-thesis show, used as a test to verify the success of my first year of work. Chapter 6 then documents the creation of the remainder of Conversations with my Sister, while chapter 7 once again documents the creation of my final thesis show. Chapter 8 details the results of the final performance of my thesis show. Finally, Chapter 9 briefly details the discoveries that I made throughout this process. My journey led me to the discovery of my creative writing ability, my eagerness to be vulnerable, and my ability to find joy hidden by pain. This document details the immense progress I have made academically, creatively, and personally that enabled my ability to create the performance Conversations with my Sister.
What do masculinities have to do with college men's help-seeking for depression-related symptoms?
Creators: name: Tang, May On Ting
Publisher: name: University of British Columbia
Year: 2011

description: Few authors have specifically analyzed college men’s help-seeking for depression. Those studies that have focused on the relationship between college men’s attitudes towards seeking psychological help and the male gender role are limited in that they neglect to contextualize help-seeking behaviours. Earlier studies have also assumed that all college men adhere to traditional masculine ideals in their help-seeking decision-making. This qualitative study analyzed 21 interviews with college men who self-reported as having either clinical depression or symptoms of depression. In acknowledging the multiplicity of masculinities, this study used social constructionism to explore the way in which college men enact their masculinities in various help-seeking contexts for depression-related symptoms. Four key themes were identified: conforming to social norms, maintaining stoicism and limiting self-disclosure around friends and peers, family validating the need for professional help, and preserving autonomy. This study also examined the interplay between college men’s masculinities and their perception of help-seeking for depression symptoms. The findings demonstrate the college men’s masculine ideals surrounding help-seeking for mental illnesses.

description: Granovetter's "strength of weak ties" hypothesizes that isolated social ties offer limited access to external prospects, while heterogeneous social ties diversify one's opportunities. We analyze the most complete record of college student interactions to date (approximately 80,000 interactions by 290 students -- 16 times more interactions with almost 3 times more students than previous studies on educational networks) and compare the social interaction data with the academic scores of the students. Our first finding is that social diversity is negatively correlated with performance. This is explained by our second finding: highly performing students interact in groups of similarly performing peers. This effect is stronger the higher the student performance is. Indeed, low performance students tend to initiate many transient interactions independently of the performance of their target. In other words, low performing students act disassortatively with respect to their social network, whereas high scoring students act assortatively. Our data also reveals that highly performing students establish persistent interactions before mid and low performing ones and that they use more structured and longer cascades of information from which low performing students are excluded.

description: We study the finitary version of the coalgebraic logic introduced by L. Moss. The syntax of this logic, which is introduced uniformly with respect to a coalgebraic type functor, required to preserve weak pullbacks, extends that of classical propositional logic with a so-called coalgebraic cover modality depending on the type functor. Its semantics is defined in terms of a categorically defined relation lifting operation. As the main contributions of our paper we introduce a derivation system, and prove that it provides a sound and complete axiomatization for the collection of coalgebraically valid inequalities. Our soundness and completeness proof is algebraic, and we employ Pattinson's stratification method, showing that our derivation system can be stratified in countably many layers, corresponding to the modal depth of the formulas involved. In the proof of our main result we identify some new concepts and obtain some auxiliary results of independent interest. We survey properties of the notion of relation lifting, induced by an arbitrary but fixed set functor. We introduce a category of Boolean algebra presentations, and establish an adjunction between it and the category of Boolean algebras. Given the fact that our derivation system involves only formulas of depth one, it can be encoded as a endo-functor on Boolean algebras. We show that this functor is finitary and preserves embeddings, and we prove that the Lindenbaum-Tarski algebra of our logic can be identified with the initial algebra for this functor.

description: Historical scholarship on British-German relations prior to 1914 often emphasizes mutual antagonism. This antagonism, supposedly, reached a nadir during the First World War, with ‘the Hun’ being demonized as the enemy to civilization, but was replaced with a more sympathetic narrative after 1919, rooted in a reaction against the allegedly punitive peace settlement. This conventional view is too simplistic. Pre-war British historians overwhelmingly adopted favourable attitudes towards Germany, and often used their professional writing to encourage congenial relations between the two countries. Conceptually, their arguments centred upon the ‘two Germanies’ thesis, an abstraction which enabled British admiration for German cultural and intellectual achievements to exist in tension with fears concerning Prussia militarism. This literature shaped demi-official British views on Germany before the war, which were anti-Prussian rather than anti-German in orientation. The ‘two Germanies’ thesis continued to influence how historians conceptualized Germany after hostilities erupted in 1914. Following the war, this continuity enabled Germanophile historians to retain an idealistic view of Germany. This conviction led them to embrace and disseminate revisionist interpretations which posited that the European Powers shared responsibility for the conflict. The idea that all the belligerent states were equally responsible for the war encouraged the view that the grievances which a relatively ‘guiltless’ Germany sought to redress were legitimate. Germanophile historians occupied a central role in supplying the vocabulary by which politicians could frame post-war reconciliation. Placed within this context, pro-German historians provided the intellectual and moral justification for sympathetic policies towards Weimar Germany. There can be no doubt that the appeasement policies adopted in the 1930s resulted in part from the conciliatory atmosphere that historians inculcated in the previous decades.

description: The goal of this thesis was to enable high repetition rate Laser Wakefield Acceleration(LWFA) by solving heat induced grating deformation issues in a Chirped PulseAmplification (CPA) based 25 TW Ti:sapphire laser system centred at 800 nm. Thesepreviously limited the intensity and wavefront quality of the pulse. An increase of maximumrepetition rate, limited by heat induced grating deformation, from 1 to 10 Hz wasachieved. Through simulations it was shown that the grating deforms due to heatingup from absorbed laser energy which induces spatial-distortions in the wavefront. Byreplacing the NZK-7 based grating with one made from ZERODURR , a glass ceramicproduced by the Schott AG with a vanishing thermal expansion coefficient a, it wasexpected, and later verified through measurements, that the introduction of such distortionsinto the beam wavefront could be inhibited. During operating at 10 Hz, thefocal spot size of the far field was measured to increase from 51 mm to 204 mm inthe vertical-, and 61 mm to 202 mm in the horizontal axis within 5 minutes usingthe NZK-7 grating and kept growing to 244 mm in the vertical-, and 434 mm inthe horizontal axis over 8 hours. With the Zerodur grating installed it stayed constantin both axis at 51 mm during the whole measurement. It was also possible to reducethe change in position of the focus by one order of magnitude. Lastly, a RadioFrequency (RF) plasma cleaning setup was successfully tested and implemented intothe compressor chamber to remove the Carbon layer that was coated onto the gratingsurface by the high intensity of the laser. Heat induced grating deformation is one ofthe things that inhibit high repetition rate LWFA experiments. In summary, this thesispresents a possibility to resolve these challenges.

description: Hydrodynamic theory of the spinor BEC condensate with Rashba spin-orbit coupling is presented. A close mathematical analogy of the Rashba-BEC model to the recently developed theory of chiral magnetism is found. Hydrodynamic equations for mass density, superfluid velocity, and the local magnetization are derived. The mass current is shown to contain an extra term proportional to the magnetization direction, as a result of the Rashba coupling. Elementary excitations around the two known ground states of the Rashba-BEC Hamiltonian, the plane-wave and the stripe states, are worked out in the hydrodynamic framework, highlighting the cross-coupling of spin and superflow velocity excitations due to the Rashba term.

description: With increase in application complexity, the need for network faults diagnosis for end-users has increased. However, existing failure diagnosis techniques fail to assist the endusers in accessing the applications and services. We present DYSWIS, an automatic network fault detection and diagnosis system for end-users. The key idea is collaboration of end-users; a node requests multiple nodes to diagnose a network fault in real time to collect diverse information from different parts of the networks and infer the cause of failure. DYSWIS leverages DHT network to search the collaborating nodes with appropriate network properties required to diagnose a failure. The framework allows dynamic updating of rules and probes into a running system. Another key aspect is contribution of expert knowledge (rules and probes) by application developers, vendors and network administrators; thereby enabling crowdsourcing of diagnosis strategy for growing set of applications. We have implemented the framework and the software and tested them using our test bed and PlanetLab to show that several complex commonly occurring failures can be detected and diagnosed successfully using DYSWIS, while single-user probe with traditional tools fails to pinpoint the cause of such failures. We validate that our base modules and rules are sufficient to detect infrastructural failures causing majority of application failures.
All my online relations: Aboriginal community participation in planning for Alberta SuperNet broadband technology

description: This thesis examines the community involvement of three Aboriginal communities in their participatory research activities around the topic of the Alberta Super Net. The researcher worked alongside three groups representing the Blackfoot, Cree, and Metis people of Alberta as part of a research partnership where the goal of the project was community empowerment through active involvement in planning activities for the introduction of the Alberta Super Net broadband technology. While development support communication provided the theoretical foundation for this study, an ethnography of the research process across the three communities formed the final methodology. Findings from this study implied that awareness and recognition of a need for directed social change within communities remain critical first stages to genuine participation within participatory research activities. This study also revealed that emerging efforts in developing culturally appropriate forms of Aboriginal research must be supported and prioritized for the immediate and social good of Aboriginal people.

The method is applicable to the investigation of high angular momentum instabilities, similar to those found by Dotti and Gleiser for Gauss-Bonnet black holes. The method does not require the knowledge of the explicit analytic form of the black hole solution. In this paper we apply our method to a case where the explicit solution is known and show that it identifies correctly the resulting unstable modes.

description: The inadequacy of the Superpave high temperature specification parameter, G*/sin 8, to correctly grade the superior field performance of modified asphalt binders has been demonstrated by several researchers. A new parameter that is blind to modification type and is performance based is now needed. As a replacement for the existing high temperature binder parameter (G*/sin 8), this study has developed an easy to use Multiple Stress Creep and Recovery Test (MSCR) that measures fundamental characteristics of asphalt binders. In this study, several binder parameters proposed to replace the existing Superpave rutting parameter were validated using hot-mix testing. Several different binder tests were evaluated to determine which would provide a replacement for the Superpave high temperature binder criteria. The new test and criteria will have to be performance related and blind to modification. The results from these binder tests were compared against hotmix rutting results from the Asphalt Pavement Analyzer, the Hamburg Wheel Tracking Test, the FHWA ALF test sections and field roadway sites. The results from the hot-mix rut testing showed that different rut testers will provide completely different ranking of binders. This difference is related to the stress level applied by the different testers. This hot-mix testing indicates that the different binders, specifically the polymer modified binders, have different stress dependencies. A separate sub-study was also conducted in this research to understand the effect of stress and strain on the microstructure of polymer modified binders. It was found that in MSCR data there is a clear relationship between percent recovery in the recovery portion of the test and percent strain in the creep portion of the test. Very high creep strain causes yield behavior in polymer modified asphalt binders (PMA). After the high creep strain, PMA's still exhibit recovery but the rate of recovery is reduced. At high strain, binder morphology, tensile and shear properties change. A test procedure was developed to run creep and recovery testing on one sample at multiple stress levels (MSCR). This test procedure makes it easy to evaluate how the binder response will change under different stress conditions. A property called nonrecoverable compliance lnr was developed based on the non-recovered strain at the end of the recovery portion of the test divided by the initial stress applied during the creep portion of the test. The Inr value normalizes the strain response of the binder to stress which clearly shows the differences between different polymer-modified binders.

description: It is thought that the final product of the gravitational collapse is a Kerr black hole and astronomers have discovered several good astrophysical candidates. While there is some indirect evidence suggesting that the latter have an event horizon, and therefore that they are black holes, a proof that the space-time around these objects is described by the Kerr geometry is still lacking. Recently, there has been an increasing interest in the possibility of testing the Kerr black hole hypothesis with present and future experiments. In this paper, I briefly review the state of the art of the field, focussing on some recent results and work in progress.

description: Task switching and interruptions are a daily reality in software development projects: developers switch between Requirements Engineering (RE), coding, testing, daily meetings, and other tasks. As developing software involves a mix of analytical and creative work, and requires a significant load on brain functions, such as working memory and decision making, task switching in the context of software development imposes a cognitive load that causes software developers to lose focus and concentration thereby taking a toll on their productivity. Task switching may increase productivity through increased information flow and effective time management. However, it might also cause a cognitive load to reorient the primary task, which accounts for the decrease in developers? productivity and increases in errors. Thus, there is a need to understand and explore the multitasking behavior of software developers to model the factors that make task switchings more disruptive in development tasks through a multidisciplinary combination of software engineering, cognitive psychology, information visualization, and machine learning researches. Moreover, recent advances in visual analytics, e.g. visual storytelling, natural language processing, and classification methods offer an opportunity to advance the understanding of and support for multitasking in software development teams through the integration of cognitive psychology, machine learning, and information visualization. This dissertation studies the behavior of multitasking and task switching in software development teams through designing and implementing five in-depth comprehensive, explorative and retrospective studies aiming at explorations of the concept of task switching and interruption in the context of software development as well of the operationalization of the interruption characteristics that impact the vulnerability of development tasks to task switching. Following the outcomes of these explorations, and to assist analysts by identifying relevant information from documental sources during an interactive interview or after resuming an information-intensive task, a novel machine learning technique is proposed to dynamically extract requirements-relevant knowledge from existing documents. On the technical side, this technique proposes to use non-contiguous n-gram kernels in the context of requirements classification and applies rational kernels combined with SVMs to model and analyze the incoming information in real-time.
A Water and Sanitation Needs Assessment for Kisumu City, Kenya

description: The city of Kisumu is located in Western Kenya, on the shores of Lake Victoria, the second largest fresh water lake in the world; yet the city is characterized by chronic water shortages. Research on the water sector in Kisumu City also shows that water and sanitation services are not keeping pace with the rapid population growth. Many low-income residents living in informal settlements and peri-urban areas lack access both to clean water and to safe and environmentally sound sanitation facilities. The city desperately needs an efficient water supply system and improved sanitation services. Hygiene education also needs to be accorded priority, mainly because water-borne diseases such as cholera, dysentery and typhoid contribute to numerous deaths every year.

description: Recommender systems have become increasingly popular. Most research on recommender systems has focused on recommendation algorithms. There has been relatively little research, however, in the area of generalized system architectures for recommendation systems. In this paper, we introduce weHelp - a reference architecture for social recommender systems. Our architecture is designed to be application and domain agnostic, but we briefly discuss here how it applies to recommender systems for software engineering.

description: The ability to recruit and confer social aid has influenced survival and reproductive outcomes for individuals throughout human evolution. In order to optimize partner choice and the allocation of prosocial benefits, natural selection has given rise to psychological mechanisms that calculate a target individual’s social value. The current study analyzes data derived from three cross-national studies finding high cross-cultural agreement regarding the acts, traits, and characteristics that increase social value, or one’s status in the minds of others. Debate regarding the extent to which culture shapes cognition (i.e., W.E.I.R.D. problem), has led researchers to develop a measure that captures how psychologically different societies are from each other, known as cultural distance. The current study examines the utility of this measure, alongside language and physical distance, in explaining cross-cultural variation in the domain of human social valuation. Multilevel analyses revealed that cross-cultural agreement in social valuation criteria was not reliably associated with any distance measure; that is, greater levels of cultural distance was not associated with less between-nation agreement in the domain of social valuation. Future research should examine the relationship between cultural distance and cross-cultural similarity in other psychological domains.
