description: We investigate new generalizations of the Meixner polynomials on the lattice $\mathbb{N}$, on the shifted lattice $\mathbb{N}+1-β$ and on the bi-lattice $\mathbb{N}\cup (\mathbb{N}+1-β)$. We show that the coefficients of the three-term recurrence relation for the orthogonal polynomials are related to the solutions of the fifth Painlevé equation P$_{\textup V}$. Initial conditions for different lattices can be transformed to the classical solutions of P$_{\textup V}$ with special values of the parameters. We also study one property of the Bäcklund transformation of P$_{\textup V}$.

description: For a bipartite honeycomb lattice, we show that the Berry phase depends not only on the shape of the system but also on the hopping couplings. Using the entanglement entropy spectra obtained by diagonalizing the block Green's function matrices, the maximal entangled state with the eigenvalue $λ_m=1/2$ of the reduced density matrix is shown to have one-to-one correspondence to the zero energy states of the lattice with open boundaries, which depends on the Berry phase. For the systems with finite bearded edges along $x$-direction we find critical hopping couplings: the maximal entangled states (zero-energy states) appear pair by pair if one increases the hopping coupling $h$ over the critical couplings $h_c$s.

An exploration of postcolonial feminist public pedagogy of an Anganwadi union on Facebook
Creators: name: Gupta, Neha
Publisher: name: University of British Columbia
Year: 2022

description: This thesis explores of the pedagogical implications of a Facebook page of a Delhi-based Anganwadi Union known as the Delhi State Anganwadi Workers and Helpers Union (DSAWHU). DSAWHU represents the voices of thousands of women community healthcare workers treated as petty workers or volunteers—women who are struggling to make improvements in their lives for many years and who have been marginalized in neoliberal India. The purpose of this study was to know about the ways in which DSAWHU leaders manage to engage their followers, educate Anganwadis about citizenship and emerge as public pedagogues, with an intention to create a social movement. For this study, I have conceptualized Facebook as a public space for education and learning. Looking at this space through the lens of postcolonial feminist theory and the theory of feminist pedagogy, I attempted to deepen our academic understanding of the concept- “postcolonial feminist public pedagogy.” Employing multimodal content analysis as a qualitative research methodology, I analyzed the multiple modes of communication that are evident on this Union’s Facebook Page. The data analysis is based on my feminist epistemic sense that is constructed from my lived experience in both urban and rural parts of India, and my personal experience with an Anganwadi a few years ago. By making meaning of the virtual communication on Facebook and understanding the Union leader and moderators as public pedagogues, and followers as learners, I found that the feminist engagement strategies of this Union to empower their communities through education appears a bit differently than is understood in the most Eurocentric literature of feminist and public pedagogy for community building and liberation. Also, if moderated carefully, considerably and with utmost dedication and a focussed purpose, unions like Anganwadis can gain worldwide attention on social media such as Facebook, which they don’t get otherwise. This can create a public narrative about the feminism of marginalized communities of India on social media platforms, which could expand our knowledge about the transnational feminist movement.

description: The singularity structure and the corresponding asymptotic behavior of a 3-brane coupled to a scalar field or to a perfect fluid in a five-dimensional bulk is analyzed in full generality using the method of asymptotic splittings. In the case of the scalar field, it is shown that the collapse singularity at a finite distance from the brane can be avoided only at the expense of making the brane world-volume positively or negatively curved. In the case where the bulk field content is parametrized by an analogue of perfect fluid with an arbitrary equation of state P=γρbetween the `pressure' P and the `density' ρ, our results depend crucially on the constant fluid parameter γ: (i) For γ>-1/2, the flat brane solution suffers from a collapse singularity at finite distance, that disappears in the curved case.

description: We revisited the decaying dark matter (DDM) model, in which one collisionless particle decays early into two collisionless particles, that are potentially dark matter particles today. The effect of DDM will be manifested in the cosmic microwave background (CMB) and structure formation. With a systematic modification of CMB calculation tool \texttt{camb}, we can numerically calculated this effect, and compare it to observations. Further Markov Chain Monte Carlo \texttt{cosmomc} runnings update the constraints in that model: the free streaming length $λ_{FS}\lesssim0.5$Mpc for nonrelativistic decay, and $((M_{DDM}/keV) Y)^2 (T_d/yr)\lesssim5\times10^{-5}$ for relativistic decay.

title: Does it matter why we hack? – Exploring the impact of goal alignment in hackathons
Creators: name: Medina Angarita, Maria Angelica
name: Nolte, Alexander
Publisher: name: European Society for Socially Embedded Technologies (EUSSET)
Year: 2019

description: Time-bounded events such as hackathons have become increasingly popular in recent years. During these events participants typically form teams, exercise fast prototype development, challenge themselves to innovate, practice new skills, collaborate with diverse team members, and compete against other teams. Hackathon organizers have a certain vision in mind about which outcome they would like to achieve and design the event based on this vision. Participants on the other hand do not necessarily share the same vision and come with their own goals and aspirations. While work in related fields suggests that it is important for goals of organizers and participants to align in order to achieve them this might be different in hackathons due to their unique setup. Drawing from literature we identified potential goals of organizers and participants and conducted a case study of three hackathons focusing on the alignment of goals between organizers and participants. Our findings indicate that the goals of organizers and participants did not align in all cases, that goal awareness on the part of the organizers appears may have a stronger impact on goal achievement and that hackathons appear to have inherent characteristics that can materialize even when not planned for.
Geometric aspects of the periodic $μ$-Degasperis-Procesi equation

description: We consider the periodic $\muDP$ equation (a modified version of the Degasperis-Procesi equation) as the geodesic flow of a right-invariant affine connection $\nabla$ on the Fréchet Lie group $\Diff^{\infty}(§^1)$ of all smooth and orientation-preserving diffeomorphisms of the circle $§^1=\R/\Z$. On the Lie algebra $\C^{\infty}(§^1)$ of $\Diff^{\infty}(§^1)$, this connection is canonically given by the sum of the Lie bracket and a bilinear operator. For smooth initial data, we show the short time existence of a smooth solution of $\muDP$ which depends smoothly on time and on the initial data. Furthermore, we prove that the exponential map defined by $\nabla$ is a smooth local diffeomorphism of a neighbourhood of zero in $\C^{\infty}(§^1)$ onto a neighbourhood of the unit element in $\Diff^{\infty}(§^1)$. Our results follow from a general approach on non-metric Euler equations on Lie groups, a Banach space approximation of the Fréchet space $\C^{\infty}(§^1)$, and a sharp spatial regularity result for the geodesic flow.

THz emission from intrinsic Josephson junctions at zero magnetic field via breather auto-oscillations

description: I propose a new mechanism of intense high-frequency electromagnetic wave generation by spatially uniform stacked Josephson junctions at zero magnetic field. The ac-Josephson effect converts the dc-bias voltage into ac-supercurrent, however, in the absence of spatial variation of Josephson phase difference, does not provide dc-to-ac power conversion, needed for emission of electromagnetic waves. Here I demonstrate that at geometrical resonance conditions, the spatial homogeneity of phase can be spontaneously broken by appearance of breathers (bound fluxon-antifluxon pairs), facilitating effective dc-to-ac power conversion. The proposed mechanism explains all major features of recently observed THz radiation from large area Bi$_2$Sr$_2$CaCu$_2$O$_{8+x}$ mesa structures.

description: The transtheoretical model (TTM) of behavioral change posits that individuals move through five stages of change when adopting new behaviors: pre-contemplation, contemplation, preparation, action, and maintenance. The aim of this study was to determine the proportion of patients with HIV/AIDS within a Ugandan fishing community in the different physical activity (PA) stages. We also explored differences in variables, motives, and barriers for PA across the stages. In total, 256 individuals (77 men, 40.5 ± 10.3 years) completed the Patient-centered Assessment and Counseling for Exercise Questionnaire, the Patient Health Questionnaire-9 (PHQ-9) to assess depressive symptoms, and the Alcohol Use Disorders Identification Test. They were also asked about their most important PA motive and barrier. Seventy-five individuals (29%) were in the (pre-)preparatory stages, 140 (55%) in the action and 41 (16%) in the maintenance stage. Those in the (pre-)preparatory stages had higher PHQ-9 total scores (p p p = 0.015). Depression and barriers to PA should be considered in people with HIV/AIDS in low-resource settings when implementing interventions to assist them to become more active.Implications for rehabilitationPeople with HIV/AIDS are among the most physically inactive clinical populations.Clinicians should consider depression when motivating patients with HIV in low resourced settings to become active.Clinicians should consider body weakness when motivating patients with HIV in low resourced settings to become active.

description: Data collection applications on smartphone devices support indigenous communities in developing countries to record and preserve traditional ecological knowledge, collaboratively collect data around issues that are important to them and use these tools to subsequently identify locally-acceptable solutions with global impacts. Development of these interfaces needs to consider users’ familiarity with technology as well as their education and literacy levels. This study builds on existing HCI4D research, which is also of interest to the CSCW community, in order to develop and evaluate, for their usability and user preferences, four user interfaces with low-literate people in the UK. Our findings suggest that linear navigation structures and a tangible interface are almost equally usable and preferred when they require minimum interaction with the device. Our preliminary analysis provides a deeper insight into the design issues to inform development of smartphone-based interfaces using various interaction types and we report on our methodological challenges from carrying out HCI research with low-literate people in the UK. The findings of this paper are used to inform the experimental design of additional work that we carry out with low-literate users in Namibia.

description: We study a combined model of black hole - accretion disk - magnetosphere - jet symbiosis, applicable for supermassive black holes. We quantify the mass and spin evolution and we analyze how the limiting value of the spin parameter and the conversion efficiency of accreted mass into radiation depend on the interplay of electromagnetic radiation reaction, magnetosphere characteristics and truncation radius of radiation. The dominant effect comes from the closed magnetic field line region, which reduces the spin limit to values ~0.89 (instead ~0.99 in its absence). Therefore observations on black hole spins could favour or disfavour the existence of the closed magnetic field line region (or its coupling to the disk). We also find that the suppression of radiation from the innermost part of the accretion disk, inferred from observations, and a collimated jet both increase the spin limit and the energy conversion efficiency.

description: This paper presents some exploratory reflections on flash fiction as a possible method to spark discussion and collaborative interpretation of qualitative research data. A growing body of work in HCI and CSCW examines the potential of techniques used in creative writing and creative fiction to generate design concepts, and narrative data analysis is adopted by social science using creative writing techniques for qualitative data work. Here we discuss our experience of an exercise where flash fiction was used not as a technique in support of design (which has been done before in human-centred computing), but as a means of probing data and facilitating collaborative data work among researchers. We reflect on the experience and outcomes of the exercise and also discuss exploratory ideas regarding how creative writing techniques could be further explored in human-centred computing as a way to probe findings from empirical data, particularly for collaborative teams.

description: The possibility of measuring redshift space (RSD) distortions using photometric data have been recently highlighted. This effect complements and significantly alters the detectability of baryon acoustic oscillations (BAO) in photometric surveys. In this paper we present measurements of the angular correlation function of luminous red galaxies (LRGs) in the photometric catalog of the final data release (DR7) of the Sloan Digital Sky Survey II (SDSS). The sample compromise ~ 1.5 x 10^6 LRGs distributed in 0.45 < z < 0.65, with a characteristic photometric error of ~ 0.05. Our measured correlation centered at z=0.55 is in very good agreement with predictions from standard LCDM in a broad range of angular scales, $0.5^\circ < θ< 6^\circ$. We find that the growth of structure can indeed be robustly measured, with errors matching expectations. The velocity growth rate is recovered as $f σ_8 = 0.53 \pm 0.42$ when no prior is imposed on the growth factor and the background geometry follows a LCDM model with WMAP7+SNIa priors. This is compatible with the corresponding General Relativity (GR) prediction $f σ_8 = 0.45$ for our fiducial cosmology. If we adopt a parametrization such that $f=Ω^γ_m(z)$, with $γ\approx 0.55$ in GR, and combine our $fσ_8$ measurement with the corresponding ones from spectroscopic LRGs at lower redshifts we obtain $γ=0.54 \pm 0.17$. In addition we find evidence for the presence of the baryon acoustic feature matching the amplitude, location and shape of LCDM predictions. The photometric BAO feature is detected with 98 % confidence level at z=0.55.

description: A new kind of deicing coating is developed to provide aircraft with efficient and durable protection from icing-induced dangers. The icing wind tunnel experiment is indispensable in confirming the usefulness of a deicing coating. Due to the high cost of each batch relative to the available budget, an efficient design of the icing wind tunnel experiment is crucial. The challenges in designing this experiment are multi-fold. It involves between-block factors and within-block factors, incomplete blocking with random effects, related factors, hard-to-change factors, and nuisance factors. Traditional designs and theories cannot be directly applied. To overcome these challenges, we propose using a step-by-step design strategy that includes applying a cross array structure for between-block factors and within-block factors, a group of balanced conditions for optimizing incomplete blocking, a run order method to achieve the minimum number of level changes for hard-to-change factors, and a zero aliased matrix for the nuisance factors. New (theoretical) results for D-optimal design of incomplete blocking experiments with random block effects and minimum number of level changes are obtained. Results of the experiments show that this novel deicing coating is promising in offering both high efficiency of ice reduction and a long service lifetime. The methodology proposed here is generalizable to other applications that involve nonstandard design problems. Supplementary materials for this article are available online.
High-Rate Vector Quantization for the Neyman-Pearson Detection of Correlated Processes

description: This paper investigates the effect of quantization on the performance of the Neyman-Pearson test. It is assumed that a sensing unit observes samples of a correlated stationary ergodic multivariate process. Each sample is passed through an N-point quantizer and transmitted to a decision device which performs a binary hypothesis test. For any false alarm level, it is shown that the miss probability of the Neyman-Pearson test converges to zero exponentially as the number of samples tends to infinity, assuming that the observed process satisfies certain mixing conditions. The main contribution of this paper is to provide a compact closed-form expression of the error exponent in the high-rate regime i.e., when the number N of quantization levels tends to infinity, generalizing previous results of Gupta and Hero to the case of non-independent observations. If d represents the dimension of one sample, it is proved that the error exponent converges at rate N^{2/d} to the one obtained in the absence of quantization. As an application, relevant high-rate quantization strategies which lead to a large error exponent are determined. Numerical results indicate that the proposed quantization rule can yield better performance than existing ones in terms of detection error.

description: Pokémon GO is one of the few location-based mobile games (LBMG) which gained popularity all over the world. It increases physical activity when players are walking around catching Pokémon. It also shapes the players’ sense of place and increases their social interactions. This exploratory auto-ethnographic study seeks to provide a first glimpse at how players appropriate different tools to inform themselves, collaborate with other players to catch or trade Pokémon and fulfill tasks inside the game together with a worldwide community. Results indicate that young adults learn how to organize catching events, arrange raid sessions, and collaborate within the Pokémon GO world and outside in the real world. This implies that the observed skills resulting from the gamification design elements of Pokémon GO can be transformed into the work life of young adults. Our explorative paper tries to pave the way for other research.

description: While feedback, by experts or peers, is found to have positive effects on crowdsourcing work, it is a costly approach as more people or time is involved in order to provide feedback. This paper explores an automatic feedback display called AuDi for crowdsourcing. AuDi shows the worker’s accuracy rate, which is automatically calculated with the use of an accuracy algorithm, by changing the background color of the task page. We conducted an experimental study with AuDi in the field, and employed both quantitative and qualitative methods for data collection and analysis. Our study shows that, without introducing new cost, such an auto-feedback display is well received by our participants, gives them assurance and more confidence, and also positively contributes to work performance by pushing them to study more and understand better the task requirements.

Experimental and numerical investigations on the lateral response of post-tensioned base rocking steel bridge piers
Creators: name: Rahmzadeh, Ahmad
Publisher: name: University of British Columbia
Year: 2023

description: This doctoral dissertation is aimed at contributing to the further development of the rocking isolation concept and posttensioning technology in bridges by proposing an unbounded post-tensioned (PT) steel pier. The proposed pier consists of a circular steel tube, circular end plates, prestressed tendon(s), and supplemental energy dissipation devices, and is configured to rock at its interface with the foundation. The main characteristic of such a pier is its ability to ensure small residual drifts after undergoing inelastic deformations during cyclic loading. The system has a tendency to close the gap due to the presence of superstructure dead load and tendon prestressing force. An experimental program was designed that included a series of quasi-static cyclic tests on 1/3-scale specimens with the objective of investigating the effects of column diameter-to-thickness ratio, base plate, and energy dissipaters and their locations on the lateral cyclic response. A component testing program was also conducted to characterize the cyclic loss of post-tension force due to wedge seating in a typical monostrand anchorage system. Using the experimental data, the calibration of the finite element (FE) procedure was done at material, component, and global system levels. The FE models were leveraged to conduct a comprehensive parametric study with the purpose of developing design criteria to minimize residual pier drifts after sustaining cyclic inelastic deformations. Using nonlinear time history FE analyses, the seismic response of a bridge incorporating such a pier was examined to evaluate the effects of different design parameters. The cyclic behaviour of buckling-restrained energy dissipating steel bars was studied. Extensive experimental and FE investigations on the cyclic behaviour of such energy dissipation devices were conducted. The results of the investigations demonstrate that a PT base rocking steel pier could exhibit a stable and robust self-centering response under severe quasi-static cyclic loading, with minimal damage to the column and most of the hysteretic energy confined within the replaceable elements. The results of dynamic FE studies show that a bridge utilizing such a pier has the potential to undergo consecutive earthquakes without sustaining significant damage and return to its original position without requiring abutment component stiffness and strength.

description: Many groupware applications use hierarchical file systems, cloud storage or shared desktop operating system disks to support the cooperative development of shared artefacts or to share information. In these collaboration scenarios, often file synchronizers assist users in the data management across multiple devices. They establish consistency between file systems, even in light of their heterogeneity. However, the development of file synchronizers is difficult due to the fact that mainstream operating systems were not primarily built for cooperation or synchronization scenarios. Further, synchronizers need to address heterogeneity, by translating semantical differences and considering cross-device and cross-file system incompatibilities. This paper provides an in-depth analysis of six file system capabilities relevant to shared data synchronizers, such as mapping from namespace to physically stored objects, supported object types, namespace limitations or locking mechanisms. For each capability we derive commonalities for a set of selected file systems and also provide advice for handling incompatibilities. The insights of this work provide useful concepts and guidance for groupware developers that aim for a better user experience in synchronization support.

description: Field deployment research represents a promising way for understanding how technology is utilised in the wild. It gained relevance in both HCI and CSCW, and allows, for instance, to investigate how technology is socially embedded in real world contexts. However, such enterprises are considered complex in nature due to continuously changing conditions such as practices surrounding technology. In situ research has yet to gain momentum, leaving researchers with little theoretical guidance. In response, the present paper proposes the application of classic grounded theory in longitudinal field deployment studies for ambient displays. We argue that the methodology is a valuable choice in cop- ing with the challenges surrounding in situ evaluations and simultaneously ensures methodological rigour. This paper contributes a practical systematisation of the methodology’s two core concepts, namely constant comparison and theoretical sampling. It sheds light on their exemplary application in investigating quantitative interaction data in the early stages of our ongoing research. With that, we hope to encourage future research and provide a first stepping stone towards developing methodological guidance for evaluations of ambient displays in the wild.

description: A star that passes too close to a massive black hole will be torn apart by tidal forces. The flare of photons emitted during the accretion of the stellar debris is predicted to be observable and candidates of such events have been observed at optical to X-ray frequencies. If a fraction of the accreted material is fed into a jet, tidal flares should be detectable at radio frequencies too, thus comprising a new class of rare radio transients. Using the well-established scaling between accretion power and jet luminosity and basic synchrotron theory, we construct an empirically-rooted model to predict the jet luminosity for a time-dependent accretion rate. We apply this model to stellar tidal disruptions and predict the snapshot rate of these events. For a small angle between the observer and the jet, our model reproduces the observed radio flux of the tidal flare candidate GRB 110328A. We find that future radio surveys will be able to test whether the majority of tidal disruptions are accompanied by a jet.

description: Collaborative ensembles will increasingly involve agents like robots in the near future. A key part of collaboration is trust. While trust has been mainly studied between humans in CSCW, trust in human-agent research has been mostly studied in dyadic formations divorced from the broader context. This exploratory paper critically discusses previous work on trust across CSCW and HCI-related areas, taking into account recent practice approaches in CSCW and what they can contribute for understanding trust in human-agent collaboration. To make better sense of how trust emerges in collaborative ensembles with agents, we suggest that concepts that have been proposed in the field of human-agent interaction need to be further explored in real-life settings, while concepts embraced in CSCW can lead to a more thorough understanding of the situatedness and dynamics of trust going beyond the attributes of the agent itself.

description: Dynamical heterogeneities -- strong fluctuations near the glass transition -- are believed to be crucial to explain much of the glass transition phenomenology. One possible hypothesis for their origin is that they emerge from soft (Goldstone) modes associated with a broken continuous symmetry under time reparametrizations. To test this hypothesis, we use numerical simulation data from four glass-forming models to construct coarse grained observables that probe the dynamical heterogeneity, and decompose the fluctuations of these observables into two transverse components associated with the postulated time-fluctuation soft modes and a longitudinal component unrelated to them. We find that as temperature is lowered and timescales are increased, the time reparametrization fluctuations become increasingly dominant, and that their correlation volumes grow together with the correlation volumes of the dynamical heterogeneities, while the correlation volumes for longitudinal fluctuations remain small.

title: Collaboration as Commodity: What does CSCW have to offer?

description: CSCW as a research field has contributed to the development of digital tools and platforms to support collaboration. Historically, detailed studies of collaboration have played a central role in the development of theories in CSCW. Parties to collaboration have been the main actors, engaged in synchronous or asynchronous, co-located or distant collaboration. CSCW has often considered the platform, i.e., the place where data about collaboration is stored, as a neutral actor without own agency or agenda. This picture has however changed drastically with the recent emergence of digital labor platforms and data- driven business models. Digital labor platforms move the focus from collaborating actors to platform owners, from supporting collaboration to trading collaboration as commodity. In this paper, I attempt to describe this development from a CSCW perspective. I propose a way to re-frame existing knowledge to fit into the new paradigm of collaboration as commodity. I propose to use research from neighboring fields such as information systems to increase our impact as CSCW researchers. Finally, I discuss several research questions for CSCW. This is work in progress.

description: In this paper, we introduce an ASEP-like transport model for bidirectional motion of particles on a multi-lane lattice. The model is motivated by {\em in vivo} experiments on organelle motility along a microtubule (MT), consisting of thirteen protofilaments, where particles are propelled by molecular motors (dynein and kinesin). In the model, organelles (particles) can switch directions of motion due to "tug-of-war" events between counteracting motors. Collisions of particles on the same lane can be cleared by switching to adjacent protofilaments (lane changes). We analyze transport properties of the model with no-flux boundary conditions at one end of a MT ("plus-end" or tip). We show that the ability of lane changes can affect the transport efficiency and the particle-direction change rate obtained from experiments is close to optimal in order to achieve efficient motor and organelle transport in a living cell. In particular, we find a nonlinear scaling of the mean {\em tip size} (the number of particles accumulated at the tip) with injection rate and an associated phase transition leading to {\em pulsing states} characterized by periodic filling and emptying of the system.

description: Lately, Indian online platforms have witnessed recurring consumer boycott calls in forms of uninstalling/down-voting applications on the app stores. For our exploratory study, we conduct a longitudinal analysis of one of these controversies involving online boycotting of an e-commerce company (Snapdeal) over a controversial statement issued by their brand ambassador (Aamir Khan) which hurt religious and nationalist sentiments of users on Twitter. Through the lens of this study, we try to understand emergent collective user behaviour and how collective action has begun to play out in online (troll) communities. We call the user behaviour in our study as trolling behaviour as - the call to boycott appears in order to silence an influential voice which challenges a nationalist narrative of these users. A broader implication of such behaviour seems to be strong arming any counter narrative with a threat of potential backlash and financial harm. This analysis is important as online deviant and trolling behaviour by group of users is increasingly influencing socio-political agendas online. It contributes to broader CSCW understanding of online platforms and collective behaviour. We also situate our work in online consumer boycotting behaviour.
