Group cohesion
Group therapeutic alliance

description: Substance Use Disorders are a major health concern in the United States. Treatment is often delivered in a group format. A feasibility study of a group treatment individuals using cocaine, based on the Transtheoretical Model of Change, yielded unexpected findings: some individuals did as well or better in the comparison group as they did in the treatment group (Velasquez et al., 2009). The goal of the current study based on these data was to determine whether group cohesion, or one’s perception of fit within the group, and group therapeutic alliance, one’s perception of connection to others and shared goals within the group, influenced treatment outcomes for participants. Questionnaires were administered at baseline, during a 12-session treatment, at post-treatment, and at a 90-day follow-up. Results showed that group cohesion and group therapeutic alliance were stronger in individuals with a higher baseline readiness-to-change. Although there was no direct effect of group cohesion or group therapeutic alliance on treatment outcomes of reduced cocaine use, individuals who developed stronger group cohesion and group therapeutic alliance were more likely to use processes of change, which in turn were related to reduced cocaine use. Group cohesion and group therapeutic alliance may play an important role in how future group treatment protocols are created, as well as how individuals are assigned to specific types of groups to maximize treatment effectiveness.
Rechtsextremismus in der Schweiz: Interventionsmöglichkeiten für die Soziale Arbeit – Fokus Jugendliche und junge Erwachsene

description: Die Covid-19 Pandemie und die damit einhergehenden Demonstrationen haben Rechtsextremist*innen in der Schweiz eine viel beachtete Plattform geboten, um unter Covidskeptiker*innen ihre Ideologie und Verschwörungstheorien zu verbreiten. Es ist wichtig, dass die Soziale Arbeit als Menschenrechtsprofession diese Tendenzen in unserer Gesellschaft wahrnimmt und Handlungsmöglichkeiten bietet. Denn ein rechtsextremes Klima begünstigt rassistische Haltungen, Aktivitäten sowie Straftaten und fördert eine Ideologie der Ungleichwertigkeit. Christoph Herzog stellt sich mit der vorliegenden Bachelorarbeit mit dem Titel «Rechtsextremismus in der Schweiz. Interventionsmöglichkeiten für die Soziale Arbeit» der Frage, was Rechtsextremismus ist und inwiefern Jugendliche und junge Erwachsene von diesem Phänomen betroffen sind. Dabei werden psychologische und soziologische Aspekte betrachtet, um aufzuzeigen, wie eine Zugehörigkeit von Jugendlichen und jungen Erwachsenen zur rechtsextremen Szene entstehen kann. Weiter wird in dieser Literaturarbeit ausgeführt, welcher Massnahmen es bedarf, damit die Soziale Arbeit Rechtsextremist*innen beim Ausstieg aus der Szene Unterstützung bieten kann. Die Situation wird aus Sicht der Sozialen Arbeit bewertet und analysiert. Der Fokus der gesamten Arbeit liegt auf Interventionen, anhand derer rechtsextremen Jugendlichen und jungen Erwachsenen ein gelingender Ausstieg aus der Szene ermöglicht werden soll.

description: It's difficult to believe that my time with this journal has come to a close. It has been one of the greatest experiences of my undergraduate career to be an integral part of its publication.
At the time of this writing, our previous issues have been read over 5,500 times, with this volume set to increase that number substantially. We have worked with undergraduates across the United States and from many other countries as well. A great thanks goes out to all our submitters. Without you there is no journal.
Though I'm moving on to other things, I trust the upcoming staff to continue in the excellent literary and aesthetic tradition which so many talented individuals have brought to life over the last two years.
I have long believed, and continue to believe, in the essential function of art and literature to a healthy democracy and a healthy civilization. I am proud to have participated, in my small way, in that tradition.

description: In the process of enlargement of the European Union (EU), monetary integration or the adoption of a common currency (Euro) for new member states is seen as the last stage of membership in this union. Indeed, this process goes through several phases identified from the beginning of this process. In fact, euroization is neither more nor less than the integration of the country's national economy into the EU. Since the early 1990s, the monetary integration of developing and transition countries has been considered as a monetary strategy for immunization against international monetary instability. In the following article, the word Euroisation is used about unilateral adoption of the euro in our country - a country in the process of EU membership – while the term "Euroization" is used throughout the text in the full sense of this notion in function of this purpose

description: This paper presents a structured power and energy-flow-based qualitative modelling approach that is applicable to a variety of system types including electrical and fluid flow. The modelling is split into two parts. Power flow is a global phenomenon and is therefore naturally represented and analysed by a network comprised of the relevant structural elements from the components of a system. The power flow analysis is a platform for higher-level behaviour prediction of energy related aspects using local component behaviour models to capture a state-based representation with a global time. The primary application is Failure Modes and Effects Analysis (FMEA) and a form of exaggeration reasoning is used, combined with an order of magnitude representation to derive the worst case failure modes. The novel aspects of the work are an order of magnitude(OM) qualitative network analyser to represent any power domain and topology, including multiple power sources, a feature that was not required for earlier specialised electrical versions of the approach. Secondly, the representation of generalised energy related behaviour as state-based local models is presented as a modelling strategy that can be more vivid and intuitive for a range of topologically complex applications than qualitative equation-based representations.The two-level modelling strategy allows the broad system behaviour coverage of qualitative simulation to be exploited for the FMEA task, while limiting the difficulties of qualitative ambiguity explanation that can arise from abstracted numerical models. We have used the method to support an automated FMEA system with examples of an aircraft fuel system and domestic a heating system discussed in this paper.

description: We report the manipulation of nitrogen vacancy (NV) spins in diamond when nearby ferrimagnetic insulator, yttrium iron garnet, is driven into precession. The change in NV spin polarization, as measured by changes in photoluminescence, is comparable in magnitude to that from conventional optically detected magnetic resonance, but relies on a distinct mechanism as it occurs at a microwave frequency far removed from the magnetic resonance frequency of the NV spin. This observation presents a new approach to transferring ferromagnetic spin information into a paramagnet and then transducing the response into a robust optical signal. It also opens new avenues for studying ferromagnetism and spin transport at the nanoscale.

Neurological Metaphor in Deep Learning: Issues and Alternatives
Creators: name: Browne, Kieran
Publisher: name: The Australian National University
Year: 2022

description: Representations of deep learning - discursive, historical and diagrammatic - are structured by a neurological metaphor that overstates a likeness to the brain and disguises other ways of understanding the technology. These neurological representations muddle the crucial public debate even as deep learning is applied in high-stakes applications, particularly in institutions of social and political power. This thesis draws on historical sources and contemporary literature to trace the development and contemporary expression of the neurological metaphor in deep learning discourse; particularly with respect to the field's terminology, the telling of its history, and the drawing of its diagrams. In the manuscript and in three documented practice-based works, I propose alternative metaphors for deep learning - divination, surveillance and memory - to highlight sociotechnical concerns posed by the technology. As a highly interdisciplinary project, this thesis applies a range of methods drawn variously from digital humanities, discourse analysis, human-centred computing, visual arts and design, and deep learning itself. The traditional scholarship and practice-based aspects of the thesis are situated in contemporary debates of AI bias and interpretability, and the role of deep learning in systems of power.

description: Magnetic properties of nanometer thick Co films intercalated at the graphene/Ir(111) interface are investigated using spin-polarized low-energy electron microscopy (SPLEEM) and Auger electron spectroscopy. We show that the graphene top layer promotes perpendicular magnetic anisotropy in the Co film underneath, even for relatively thick intercalated deposits. The magnetic anisotropy energy is significantly larger for the graphene/Co interface than for the free Co surface. Hybridization of the graphene and Co electron orbitals is believed to be at the origin of the observed perpendicular magnetic anisotropy.
Models and algorithms for haplotype phasing and variant calling
Creators: name: Li, Yanbo
Publisher: name: The Australian National University
Year: 2022

description: Haplotypes have been increasingly used in genetic studies. Analysis of variations among haplotypes has many applications in population genetics and biomedical research. However, the current DNA sequencing technologies can only read short fragments (called reads) randomly drawn from complete haplotypes, and reads from two haplotypes are mixed together for diploid species like humans. Therefore, recovering the complete haplotype sequences becomes a fundamental problem in computational genomics, which requires calling variants between two haplotypes from reads. With the emerging third-generation sequencing technologies, existing reference-based approaches for haplotype phasing suffer from performance issues to handle long and error-prone reads. At the same time, reference-free methods for variant calling and haplotype phasing meet challenges when applied to large and complex genomes. This thesis addresses a number of critical challenges in haplotype phasing and variant calling in computational genomics. Firstly, we introduce DCHap, a fast reference-based haplotype phasing algorithm that applies a divide-and-conquer strategy. This divide-and-conquer strategy improves both scalability and accuracy for handling third-generation sequencing data in haplotype phasing. Secondly, we propose an algorithm, Kmer2SNP, for reference-free variant calling using graph matching. The introduction of the heterozygous k-mer graph helps to recover SNPs between two haplotypes through the maximum weight matching. Thirdly, we describe Kmer2Haplotype, a pipeline of reference-free haplotype phasing by incorporating both short and long reads from the same individual. The problem of haplotype phasing is modeled as finding the minimum bi-partition of the haplotype-specific k-mer graph. We further design and conduct extensive experiments, and the benchmarking results show the effectiveness and efficiency of the above-proposed approaches compared to the state-of-art baselines. We finally conclude this thesis by discussing future research directions.

Capillary condensation of saturated vapor in a corner formed by two intersecting walls
Creators: name: Benilov, Eugene
Publisher: name: University of Limerick
Year: 2022
Subjects: Engineering

description: The dynamics of saturated vapor between two intersecting walls is examined. It is shown that, if the angle / between the walls is sufficiently small, the vapor becomes unstable, and spontaneous condensation occurs in the corner, similar to the so-called capillary condensation of vapor into a porous medium. As a result, an ever-growing liquid meniscus develops near the corner. The diffuse-interface model and the lubrication approximation are used to demonstrate that the meniscus grows if and only if / þ 2h < p, where h is the contact angle corresponding to the fluid/solid combination under consideration. This criterion has a simple physical explanation: if it holds, the meniscus sur?face is concave—hence, the Kelvin effect causes condensation. Once the thickness of the condensate exceeds by an order of magnitude the characteristic interfacial thickness, the volume of the meniscus starts to grow linearly with time. If the near-vertex region of the corner is smoothed, the instability can be triggered off only by finite-size perturbations, such that it includes enough liquid to cover the smoothed area by a microscopically thin liquid film.

description: Modelling, simulation and optimization form an integrated part of modern design practice in engineering and industry. Tremendous progress has been observed for all three components over the last few decades. However, many challenging issues remain unresolved, and the current trends tend to use nature-inspired algorithms and surrogate-based techniques for modelling and optimization. This 4th workshop on Computational Optimization, Modelling and Simulation (COMS 2013) at ICCS 2013 will further summarize the latest developments of optimization and modelling and their applications in science, engineering and industry. In this review paper, we will analyse the recent trends in modelling and optimization, and their associated challenges. We will discuss important topics for further research, including parameter-tuning, large-scale problems, and the gaps between theory and applications.

description: This paper presents the first on-sky demonstration of speckle nulling, which was achieved at the Subaru Telescope in the context of the Subaru Coronagraphic Extreme Adaptive Optics (SCExAO) Project. Despite the absence of a high-order high-bandwidth closed-loop AO system, observations conducted with SCExAO show that even in poor-to-moderate observing conditions, speckle nulling can be used to suppress static and slow speckles even in the presence of a brighter dynamic speckle halo, suggesting that more advanced high-contrast imaging algorithms developed in the laboratory can be applied to ground-based systems.

description: We address a dynamic repair shop scheduling problem in the context of military aircraft fleet management where the goal is to maintain a full complement of aircraft over the long-term. A number of flights, each with a requirement for a specific number and type of aircraft, are already scheduled over a long horizon. We need to assign aircraft to flights and schedule repair activities while considering the flights requirements, repair capacity, and aircraft failures. The number of aircraft awaiting repair dynamically changes over time due to failures and it is therefore necessary to rebuild the repair schedule online. To solve the problem, we view the dynamic repair shop as successive static repair scheduling sub-problems over shorter time periods. We propose a complete approach based on the logic-based Benders decomposition to solve the static sub-problems, and design different rescheduling policies to schedule the dynamic repair shop. Computational experiments demonstrate that the Benders model is able to find and prove optimal solutions on average four times faster than a mixed integer programming model. The rescheduling approach having both aspects of scheduling over a longer horizon and quickly adjusting the schedule increases aircraft available in the long term by 10% compared to the approaches having either one of the aspects alone.

description: This thesis presents research exploring aspects of inflation and cosmology in the context of inflation models in which an inflaton is non-minimally coupled to the Ricci scalar, or is considered in conjunction with a term quadratic in the Ricci scalar. We consider a ϕ2 Palatini inflation model in R2 gravity and investigate whether this model can overcome some of the problems of the original ϕ2 chaotic inflation model. We investigate the compatibility of this model with the observed CMB when treated as an effective theory of inflation in quantum gravity by examining the constraints on the model parameters arising due to Planck-suppressed potential corrections and reheating. Additionally, we consider two possible reheating channels and assess their viability in relation to the constraints on the size of the coupling to the R2 term. We present an application of the Affleck-Dine mechanism, in which quadratic B-violating potential terms generate the asymmetry, with a complex inflaton as the Affleck-Dine field. We derive the B asymmetry generated in the inflaton condensate analytically and numerically. We use the present-day asymmetry to constrain the size of the B-violating mass term and derive an upper bound on the inflaton mass in order for the Affleck-Dine dynamics to be compatible with non-minimally coupled inflation in the metric and Palatini formalisms. The baryon isocurvature fraction generated in this model is also examined against observational constraints. We demonstrate the existence of a new class of inflatonic Q-balls in a non-minimally coupled Palatini inflation model, through an analytical derivation of the Q-ball equation and numerical confirmation of the existence of solutions, and derive a range of the inflaton mass squared within which the model can inflate and produce Q-balls. We derive analytical estimates of the properties of these Q-balls, explore the effects of curvature, and discuss observational signatures of the model.

In 2011, an astounding realization of this experiment showed that perhaps this is not the case and the boundaries to our understanding of the quantum world are still far away.

description: Transitional disks are protoplanetary disks characterized by reduced near- and mid-infrared emission with respect to full disks. This characteristic spectral energy distribution indicates the presence of an optically thin inner cavity within the dust disk believed to mark the disappearance of the primordial massive disk. We present new Herschel Space Observatory PACS spectra of [OI] 63 micron for 21 transitional disks. Our survey complements the larger Herschel GASPS program "Gas in Protoplanetary Systems" (Dent et al. 2013) by quadrupling the number of transitional disks observed with PACS at this wavelength. [OI] 63 micron traces material in the outer regions of the disk, beyond the inner cavity of most transitional disks. We find that transitional disks have [OI] 63 micron line luminosities two times fainter than their full disk counterparts. We self consistently determine various stellar properties (e.g. bolometric luminosity, FUV excess, etc.) and disk properties (e.g. disk dust mass, etc.) that could influence the [OI] 63 micron line luminosity and we find no correlations that can explain the lower [OI] 63 micron line luminosities in transitional disks. Using a grid of thermo-chemical protoplanetary disk models, we conclude that either transitional disks are less flared than full disks or they possess lower gas-to-dust ratios due to a depletion of gas mass. This result suggests that transitional disks are more evolved than their full disk counterparts, possibly even at large radii.

description: We consider a single particle tunnelling in a tight-binding model with nearest-neighbour couplings, in the presence of a periodic high-frequency force. An effective Hamiltonian for the particle is derived using an averaging method resembling classical canonical perturbation theory. Three cases are considered: uniform lattice with periodic and open boundary conditions, and lattice with a parabolic potential. We find that in the latter case, interplay of the potential and driving leads to appearence of the effective next-nearest neighbour couplings. In the uniform case with periodic boundary conditions the second- and third-order corrections to the averaged Hamiltonian are completely absent, while in the case with open boundary conditions they have a very simple form, found before in some particular cases by S.Longhi [Phys. Rev. B 77, 195326 (2008)]. These general results may found applications in designing effective Hamiltonian models in experiments with ultracold atoms in optical lattices, e.g. for simulating solid-state phenomena.

description: To achieve an optimal outcome in many situations, agents need to choose distinct actions from one another. This is the case notably in many resource allocation problems, where a single resource can only be used by one agent at a time. How shall a designer of a multi-agent system program its identical agents to behave each in a different way? From a game theoretic perspective, such situations lead to undesirable Nash equilibria. For example consider a resource allocation game in that two players compete for an exclusive access to a single resource. It has three Nash equilibria. The two pure-strategy NE are efficient, but not fair. The one mixed-strategy NE is fair, but not efficient. Aumanns notion of correlated equilibrium fixes this problem: It assumes a correlation device that suggests each agent an action to take. However, such a "smart" coordination device might not be available. We propose using a randomly chosen, "stupid" integer coordination signal. "Smart" agents learn which action they should use for each value of the coordination signal. We present a multi-agent learning algorithm that converges in polynomial number of steps to a correlated equilibrium of a channel allocation game, a variant of the resource allocation game. We show that the agents learn to play for each coordination signal value a randomly chosen pure-strategy Nash equilibrium of the game. Therefore, the outcome is an efficient correlated equilibrium. This CE becomes more fair as the number of the available coordination signal values increases.

description: According to a general definition of discrete curves, surfaces, and manifolds. This paper focuses on the Jordan curve theorem in 2D discrete spaces. The Jordan curve theorem says that a (simply) closed curve separates a simply connected surface into two components. Based on the definition of discrete surfaces, we give three reasonable definitions of simply connected spaces. Theoretically, these three definition shall be equivalent. We have proved the Jordan curve theorem under the third definition of simply connected spaces. The Jordan theorem shows the relationship among an object, its boundary, and its outside area. After the publication of the first version of the paper ({\it L. Chen, Note on the discrete Jordan Curve Theorem. In: SPIE Conf. on Vision Geometry VIII, vol. 3811, pp. 82-94. (1999).}), we found some statements in the original proof of the Jordan Curve Theorem were not explained well. One case was not proven in details. In this revision, we added two more minor definitions and make the proof more solid and sound when it is needed for embedding a discrete surface into a Euclidean space. In this revision, we also proved that the third definition of simply connected spaces equivalent to the second definition of simply connected spaces.

title: Enacting Rhetorical Listening:  A Process to Support Students’ Engagement with Challenging Course Readings
Creators: name: Rivera-Mueller, Jessica

description: Many educators assign course readings to purposefully enlarge students’ perspectives. In doing so, though, educators may face a range of behaviors—reluctance, resistance, avoidance, disengagement—from students who feel that such readings negatively press upon their prior knowledge, belief systems, or educational goals. This teaching challenge is often present for social justice educators. However, “rhetorical listening,” a rhetorical theory developed by Ratcliffe (2005), is a pedagogical tool that can help shift students’ understandings of and expectations for the activity of reading, thereby creating a learning environment that supports meaningful engagement with challenging course readings. In this article, the author outlines a process for enacting rhetorical listening and describes the pedagogical outcomes that have been achieved through this process.

description: We consider a symmetric scalar theory with quartic coupling in 4-dimensions and compare the standard 2PI calculation with a modified version which uses a functional renormalization group method. The set of integral differential equations that are obtained from the exact renormalization group method truncate naturally, without the introduction of additional approximations. The results of the two methods agree well, which shows that the exact renormalization group can be used at the level of the 2PI effective action to obtain finite results without the use of counter-terms. The method therefore offers a promising starting point to study the renormalization of higher order $n$PI theories.

title: Implementation of a 25-minute Mini-lecture on Learning and Studying in Large-enrollment First-Year General Chemistry Courses

description: Poor results on the first exam in a course can be a shock to freshmen college students who found great success in high school. The experience can be demoralizing and put students in the mindset that academic success is out of reach. To convince such students that not only is academic success possible but readily achievable, I presented a 25-minute mini-lecture on learning and studying in two large-enrollment general chemistry courses (total N = 289) based on author Dr. Saundra McGuire’s work. The mini-lecture discussed human learning and practical study tools. The purposes of the mini-lecture were to: 1) examine how well students could be convinced to critically assess their learning and study habits; and 2) motivate students to believe academic success is possible. I assessed the two goals via an anonymous survey utilizing Likert scale questions and essay questions. A majority (74%) of survey respondents who reported they watched the mini-lecture (N = 158) believed the mini-lecture assisted reflection on their study habits. Sixty-six percent of respondents reported changing their study habits. However, 38% of students who reported changing their study habits eventually reverted. When allowed to provide comments about the experience, students gave generally positive responses specifically citing how the mini-lecture prompted self-reflection and how the mini-lecture demonstrated the instructor cared about student success.
title: Taking into Account Interpersonal Aspects of Teacher Feedback: Principles of Responding to Student Writing
Creators: name: Shvidko, Elena

description: Providing feedback on student work is a fundamental aspect of instruction and an important part of the learning process. A considerable amount of literature describes pedagogical value of different types of feedback--explicit vs. implicit, comprehensive vs. selective, direct vs. indirect, and feedback on content vs. feedback on form, thus treating feedback primarily as an instructional/informational phenomenon. It must be remembered, however, that there is a real person behind each paper; therefore, interpersonal aspects of teacher feedback should not be disregarded. This article discusses five principles of responding to student writing that take into account this interpersonal nature of feedback: providing positive comments, avoiding appropriating student writing, responding as a reader, involving students in the revision process, and minimizing student frustration. The author suggests that these principles can help instructors deliver supporting and encouraging feedback that will be able to demonstrate their genuine interest in students’ ideas, acknowledge students’ efforts and writing progress, respect their voice and agency, and foster their growing motivation and self-confidence as writers.
Recognition, representation, and relationships: how the UK Relationships and Sex Education Curriculum (2020) can meet the needs of and offer representation to young disabled and neurodivergent or neurodiverse people with LGBT+ identities.

description: Relationships and Sex Education (RSE) became mandatory in all secondary schools in England in September 2020. Prior to this, delivery of RSE was neither compulsory nor consistent across England, meaning student experience differed widely. Added to this is a climate of prohibitive legislation surrounding the teaching of homosexuality, leading to Lesbian, Gay, Bisexual and Transgender (LGBT+) young people to often be excluded from RSE. Special schools were also often behind mainstream schools in their delivery of RSE curricula, causing a disparity between disabled and non-disabled young people (OFSTED, 2013). This thesis takes as its starting point the idea that comprehensive RSE should allow all young people to ‘interact with each other as equals’ (Fraser, 2000, p. 36). Through a Critical Discourse Analysis, it analyses its representation of young LGBT+ people who are disabled and neurodivergent or neurodiverse at a text level. A series of phenomenological interviews examine previous experiences of young people who did not benefit from the statutory curriculum to offer a case for the need for inclusive RSE. These two elements are then combined into suggestions for practice for teachers and facilitators delivering the curriculum. This investigation makes an original contribution to research through its examination of how Relationships and Sex Education and its inclusivity contribute to young adults’ experience of participatory parity and their ability to interact with each other as equals. The findings have implications for curriculum design, social representation, and classroom practice. Keywords: Relationships and Sex Education, Disability, Curricula, Critical Discourse Analysis.

description: The Minimum Vertex Cover (MVC) problem is a prominent NP-hard combinatorial optimization problem of great importance in both theory and application. Local search has proved successful for this problem. However, there are two main drawbacks in state-of-the-art MVC local search algorithms. First, they select a pair of vertices to exchange simultaneously, which is time-consuming. Secondly, although using edge weighting techniques to diversify the search, these algorithms lack mechanisms for decreasing the weights. To address these issues, we propose two new strategies: two-stage exchange and edge weighting with forgetting. The two-stage exchange strategy selects two vertices to exchange separately and performs the exchange in two stages. The strategy of edge weighting with forgetting not only increases weights of uncovered edges, but also decreases some weights for each edge periodically. These two strategies are used in designing a new MVC local search algorithm, which is referred to as NuMVC. We conduct extensive experimental studies on the standard benchmarks, namely DIMACS and BHOSLIB. The experiment comparing NuMVC with state-of-the-art heuristic algorithms show that NuMVC is at least competitive with the nearest competitor namely PLS on the DIMACS benchmark, and clearly dominates all competitors on the BHOSLIB benchmark. Also, experimental results indicate that NuMVC finds an optimal solution much faster than the current best exact algorithm for Maximum Clique on random instances as well as some structured ones. Moreover, we study the effectiveness of the two strategies and the run-time behaviour through experimental analysis.
