Land as teacher : Decolonial practices in equity, diversity and inclusion
Creators: name: Sparrow, Corrina
Publisher: name: The University of British Columbia
Year: 2025

description: At this opening event of this year's EDI Scholars-in-Residence program, we will explore opportunities and wise-practice models for EDI and university library departments, to engage Land-based decolonial community programming and professional development activities, which are aligned with the UBC Indigenous Strategic Plan. Policies regarding decolonial EDI initiatives, and distinct implementation experiences of Indigenous strategic planning within diverse departments at the university remain under-developed. Decolonial, Land-based EDI initiatives for university library departments are also extremely rare. Local Indigenous knowledge systems, relationship building, and Land-based pedagogical frameworks can strengthen EDI initiatives, scholarship, curriculum development and teaching practices. We know that the process of decolonizing academic policy and procedures benefits greatly from local Indigenous worldviews, relationality to the Land and Water, as well as ancestral knowledge, protocols, and teachings. The principles of Equity, Diversity, and Inclusion are already intrinsically woven throughout local Indigenous epistemologies, ontologies, and methodologies. This wisdom is drawn from Indigenous relationality to the Land and Water in our ancestral territories. Gathering and synthesizing knowledge about traditional Indigenous approaches within EDI will contribute to informing and advancing initiatives which are supportive of Indigenous students, scholars, and university practice alike. Objectives: Engage university students, staff, and scholars through Land-based activities and local Indigenous cultural protocols; Explore ideas around decolonization, reciprocity, and Land-based teachings in practice; Strengthen relationality and decolonial approaches within university library departments, policies and procedures; Examine linkages between EDI initiatives, the Indigenous Strategic Plan, and local Indigenous cultural knowledge and teachings. Session Learning: How do you perceive decolonial policy and practice in university settings? What role does Land-based education and programming have within university library departments? What are Indigenous students/staff/scholars experiences of EDI at UBC? How can EDI be rooted in Indigenous ways of knowing and being?

description: LGBTQ+ individuals are increasingly turning to chatbots powered by large language models (LLMs) to meet their mental health needs. However, little research has explored whether these chatbots can adequately and safely provide tailored support for this demographic. We interviewed 18 LGBTQ+ and 13 non-LGBTQ+ participants about their experiences with LLM-based chatbots for mental health needs. LGBTQ+ participants relied on these chatbots for mental health support, likely due to an absence of support in real life. Notably, while LLMs offer prompt support, they frequently fall short in grasping the nuances of LGBTQ-specific challenges. Although fine-tuning LLMs to address LGBTQ+ needs can be a step in the right direction, it isn't the panacea. The deeper issue is entrenched in societal discrimination. Consequently, we call on future researchers and designers to look beyond mere technical refinements and advocate for holistic strategies that confront and counteract the societal biases burdening the LGBTQ+ community.

description: Understanding complex correlated oxides and their phase transitions has long been a challenge. The difficulty largely arises from the intriguing interplay between multiple degrees of freedoms. While degeneracy can play an important role in determining material characteristics, there is no well-defined way to quantify and to unveil its role in real materials having complicated band structures. Here we suggest a way to quantify the `effective degeneracy' relevant to metal-insulator transition by introducing entropy-like terms. This new quantity well describes the electronic behaviors of transition-metal oxides as a function of external and internal parameters. With $3d$ titanates, $4d$ ruthenates, and $5d$ iridates as our examples, we show that this new effective quantity provides useful insights to understand these systems and their phase transitions. For LaTiO$_3$/LaAlO$_3$ superlattice, we suggest a novel `degeneracy control' metal-insulator transition.

description: In the preceding paper we presented empirical results describing the growth of publicly-traded United States manufacturing firms within the years 1974--1993. Our results suggest that the data can be described by a scaling approach. Here, we propose models that may lead to some insight into these phenomena. First, we study a model in which the growth rate of a company is affected by a tendency to retain an ``optimal'' size. That model leads to an exponential distribution of the logarithm of the growth rate in agreement with the empirical results. Then, we study a hierarchical tree-like model of a company that enables us to relate the two parameters of the model to the exponent $β$, which describes the dependence of the standard deviation of the distribution of growth rates on size. We find that $β= -\ln Π/ \ln z$, where $z$ defines the mean branching ratio of the hierarchical tree and $Π$ is the probability that the lower levels follow the policy of higher levels in the hierarchy. We also study the distribution of growth rates of this hierarchical model. We find that the distribution is consistent with the exponential form found empirically.

description: Mussel farming is one of the most important aquaculture industries. The main risk to mussel farming is harmful algal blooms (HABs), which pose a risk to human consumption. In Galicia, the Spanish main producer of cultivated mussels, the opening and closing of the production areas is controlled by a monitoring program. In addition to the closures resulting from the presence of toxicity exceeding the legal threshold, in the absence of a confirmatory sampling and the existence of risk factors, precautionary closures may be applied. These decisions are made by experts without the support or formalisation of the experience on which they are based. Therefore, this work proposes a predictive model capable of supporting the application of precautionary closures. Achieving sensitivity, accuracy and kappa index values of 97.34%, 91.83% and 0.75 respectively, the kNN algorithm has provided the best results. This allows the creation of a system capable of helping in complex situations where forecast errors are more common.

description: The old Weyl's idea of scale recalibration freedom and the Infeld and van der Waerden (IW) ideas concerning geometrical interpretation of the natural spinor phase gauge symmetry are discussed in the context of moderm models of fundamental particle interactions. It is argued that IW gauge symmetry can be naturaly identified with U(1) symmetry of Weinberg-Salam model. It is also argued that there are no serious reasons to reject Weyl's gauge theory from the considerations. Its inclusion enriches the original Weinberg-Salam theory and leads to predictions of new phenomena that do not contradict experiments.

We investigate the trend of increasing Z* values through the series, using band-by-band decompositions and computational experiments performed on fake materials with artificially-modified covalence. The deviations of Z* from the nominal value 2 are due to the increasing interaction between O 2p orbitals and unoccupied cation d states. We also explain the variations, along the series, of the individual contributions to Z* arising from the occupied band manifolds.

description: Neutrino evolution, of great importance in environments such as neutron star mergers (NSMs) because of their impact on explosive nucleosynthesis, is still poorly understood due to the high complexity and variety of possible flavor conversion mechanisms. In this study, we focus on so-called "fast flavor oscillations", which can occur on timescales of nanoseconds and are connected to the existence of a crossing between the angular distributions of electron (anti)neutrinos. Based on the neutrino radiation field drawn from a three dimensional neutron star merger simulation, we use an extension of the two-moment formalism of neutrino quantum kinetics, and perform a linear stability analysis to determine the characteristics of fast flavor instabilities across the simulation. We compare the results to local (centimeter-scale) three-dimensional two-flavor simulations using either a moment method or a particle-in-cell architecture. We get generally good agreement in the instability growth rate and typical instability lengthscale, although the imperfections of the closure used in moment methods remain to be better understood.

description: Let $u$ denote a solution to a rotationally invariant Hessian equation $F(D^2u)=0$ on a bounded simply connected domain $Ω\subset R^2$, with constant Dirichlet and Neumann data on $\partial Ω$. In this paper we prove that if $u$ is real analytic and not identically zero, then $u$ is radial and $Ω$ is a disk. The fully nonlinear operator $F\not\equiv 0$ is of general type, and in particular, not assumed to be elliptic. We also show that the result is sharp, in the sense that it is not true if $Ω$ is not simply connected, or if $u$ is $C^{\infty}$ but not real analytic.

description: Objectives: This study analyzed adolescent physical activity, its link to overweight, and the social network structure in group sports participants, focusing on centrality measures.
 Setting: Conducted in 11 classrooms across 5 schools in Ponferrada, Spain.
 Participants: Included 235 adolescents (49.4% female), categorized as normal weight or overweight.
 Methods: The Physical Activity Questionnaire for Adolescents (PAQ-A) assessed physical activity levels. Social network analysis evaluated centrality in varying contact degrees.
 Results: 30.2% were overweight. Males scored higher in PAQ-A and were more likely to engage in group sports. No significant correlation was found between physical activity and weight in the total sample. However, overweight females reported higher exercise levels. Centrality analysis showed gender differences; women in group sports had lower centrality, whereas men had higher.
 Conclusions: The study highlights the importance of gender and social network centrality in designing future strategies, considering peer interaction intensity
VY Sculptoris stars as magnetic CVs

Year: 2002

description: We show that the absence of outbursts during low states of VY Scl stars is easily explained if white dwarfs in these systems are weakly magnetized ($μ\gta 5 10^{30}$ G cm$^{3}$). However, some of the VY Scl stars are observed to have very slow declines to minimum and similarly slow rises to maximum. The absence of outbursts during such intermediate (as opposed to low) states, which last much longer than typical disc's viscous times, can be explained only if accretion discs are absent when their temperatures would correspond to an unstable state. This requires magnetic fields stronger than those explaining outburst absence during low states, since white dwarfs in this sub-class of VY Scl stars should have magnetic moments $μ\gta 1.5 10^{33}$ G cm$^{3}$ i.e. similar to those of Intermediate Polars. Since at maximum brightness several VY Scl stars are SW Sex stars, this conclusion is in agreement with recent claims about the magnetic nature of these systems.

description: Sweet potato (Ipomoea batatas) is one of the stable tuber crops consumed by many households in Nigeria. It can be found in different varieties and exist in many colours of skin and flesh. The production of this important crop is still very low, thereby compromising food security. Sweet potato is one of the target commodity crops under the Nigerian Agriculture Sector Investment Opportunities. However, improved sweet potato production has not been widely adopted among farmers Oyo state hence, the need to investigate factors affecting the adoption of improved sweet potato varieties among farmers in Oyo state. Data were collected from 350 farmers randomly selected from two agricultural zones in the state. The data collected were presented using descriptive statistics and analysed using Tobit regression model. Results showed that farm size, age, years of formal education, early maturing, high yield potential, market availability, resistant to pests and diseases and availability of vines significantly influenced the adoption of improved sweet potato varieties. Availability of vines of improved varieties, high yield potential, early maturity, resistant to pests and diseases and market availability were the technology-specific attributes that influenced both the adoption of improved sweet potato varieties and its use intensity. The study, therefore suggests that attribute preferences of farmers need to be integrated into the development of improved sweet potato varieties by the researchers to enhance its adoption and use intensity.

description: The high capacity of the agricultural sector in Kermanshah Province needs more attention for some reasons including weather and climate conditions, access to fertile lands, and ready-made labor force. The current research seeks to achieve a major strategy for the development of entrepreneurship activities in the agricultural sector of Kermanshah Province. To reach end a mixed research method was used in which the content analysis and survey methods were used in the qualitative and quantitative phases, respectively. The content analysis and “Analysis of Hierarchy Process (AHP) were applied by using Expert Choice software for data analysis. In the quantitative part, the study population was comprised of agricultural entrepreneurs in Kermanshah Province, of which 27 participated in semi-structured interviews. In the quantitative part, a pairwise comparison questionnaire was administered to 10 entrepreneurs who were entrepreneurship experts. Based on the results obtained from the current research, the development strategy, namely “regional market development, paving the way for the development of entrepreneurial companies, and presentation of products fabricated by agricultural entrepreneurs in Kermanshah Province in regional, national, and international exhibitions”, was chosen as the best conservative strategy with the final priority of 0.347. In addition, another strategy, i.e. “the formulation of policies and establishment of appropriate support platforms for agricultural entrepreneurs by the state and organizations, such as subsidizing producers and providing facilities to entrepreneurs to facilitate access to suitable land for their activities”, with the final priority of 0.270% was chosen as the alternative strategy for the development of entrepreneurial activities in Kermanshah province.
title: ‘Staged Nostalgia’: Negotiating Identity through Encounters with the Landscapes of Conflict in Cyprus
Creators: name: Georgiou, Pauline
Publisher: name: Goldsmiths, University of London
Year: 2019

description: The thesis is an ethnography of modern day Greek Cypriot society and the struggle to establish identity and belonging through encounters with the landscape. It contributes to the anthropological literature on Cyprus and on wider literature on heritage, tourism and borders. The historical conflict that has left Cyprus divided for 44 years becomes the basis for an identity crisis which is then fuelled by internal conflicts based on perceptual dichotomies and divisions. Collectiveness is achieved through socializing mechanisms and recitals such as the proposed ‘staged nostalgia’ which involves the public and collective performance of patriotism, mourning, victimization and nostalgia. This public and private distinction and the performance of ‘staged nostalgia’ resonates throughout the thesis as encounters with the landscape shape perceptions of identity. Chapter Two introduces Greek Cypriot identities as ‘products of conflict’, covering the historical, social and politico-economic context of the suggested identity crisis. Then, four chapters approach the questions through a focus on the physical landscape and interactions with it during fieldwork. First, the contested border becomes the edge upon which identity negotiations take place. The division of the physical landscape reflects the social divisions and as the border becomes penetrable new perceptions and challenges are formed. Then, interactions with the physical landscape of loss and decay challenge notions of temporality and monumentalization. The heritage landscape becomes a space of further contestation as multiple narratives compete for legitimization. Internationalist and nationalist heritage regimes attempt to establish narratives of heritage as top-down impositions onto the landscape. At the same time, local voices and memories are lost in time and selective histories are passed on. Parallel to this, tourism spaces become opportunities for public display and consumption of the contested ‘self’ where contradicting notions such as ‘modernity’ and ‘tradition’ compete. While individuals express their struggle to conceptualize their personal relationship with identity, ‘staged nostalgia’ takes over in the public sphere to display a very particular socio-political existence.

description: Magnetars are neutron stars with extremely high magnetic fields that exhibit various X-ray phenomena such as sporadic sub-second bursts, long-term persistent flux enhancements, and variable rates of rotation period change. In 2020, a fast radio burst (FRB), akin to cosmological millisecond-duration radio bursts, was detected from the Galactic magnetar SGR 1935+2154, confirming the long-suspected association between some FRBs and magnetars. However, the mechanism for FRB generation in magnetars remains unclear. Here we report the X-ray discovery of an unprecedented double glitch in SGR 1935+2154 within a time interval of approximately nine hours, bracketing an FRB that occurred on October 14, 2022. Each glitch involved a significant increase in the magnetar's spin frequency, being among the largest abrupt changes in neutron star rotation ever observed. Between the glitches, the magnetar exhibited a rapid spin-down phase, accompanied by a profound increase and subsequent decline in its persistent X-ray emission and burst rate. We postulate that a strong, ephemeral, magnetospheric wind provides the torque that rapidly slows the star's rotation. The trigger for the first glitch couples the star's crust to its magnetosphere, enhances the various X-ray signals, and spawns the wind that alters magnetospheric conditions that might produce the FRB.

description: We construct the explicit form of three almost complex structures that a Riemannian manifold with self-dual curvature admits and show that their Nijenhuis tensors vanish so that they are integrable. This proves that gravitational instantons with self-dual curvature admit hyper-Kähler structure. In order to arrive at the three vector valued 1-forms defining almost complex structure, we give a spinor description of real 4-dimensional Riemanian manifolds with Euclidean signature in terms of two independent sets of 2-component spinors. This is a version of the original Newman-Penrose formalism that is appropriate to the discussion of the mathematical, as well as physical properties of gravitational instantons. We shall build on the work of Goldblatt who first developed an NP formalism for gravitational instantons but we shall adopt it to differential forms in the NP basis to make the formalism much more compact. We shall show that the spin coefficients, connection 1-form, curvature 2-form, Ricci and Bianchi identities, as well as the Maxwell equations naturally split up into their self-dual and anti-self-dual parts corresponding to the two independent spin frames. We shall give the complex dyad as well as the spinor formulation of the almost complex structures and show that they reappear under the guise of a triad basis for the Petrov classification of gravitational instantons. Completing the work of Salamon on hyper-Kähler structure, we show that the vanishing of the Nijenhuis tensor for all three almost complex structures depends on the choice of a self-dual gauge for the connection which is guaranteed by virtue of the fact that the curvature 2-form is self-dual for gravitational instantons.

World Economic Forum har udråbt algoritmers håndtering af big data til at udgøre en ny industriel revolution. Algoritmer eksisterer mange steder i vores samfund, og koblet til big data, er de ved at få afgørende betydning for virksomheders produktivitet, logistik, kundeinformation, marketing og meget mere. Også på finansmarkederne udgør algoritmer en af de seneste teknologiske udviklinger. Algoritmisk handel en type automatiseret handel, hvor ikke mennesker, men algoritmer træffer beslutninger om køb og salg. Gennem det seneste årti er hastighederne hvormed transaktioner udføres på finansmarkederne accelereret i sådan en grad, at aktier skifter hænder på mikrosekunder. Techno-finansielle aktiehandler skaber finansielle geografier. Men, hvorfor er hastighed blevet sådan en afgørende faktor for handel med værdipapirer? Og hvordan tjener algoritmer penge på mikrosekunder?

description: The discovery of superconductivity at 203 K in H3S brought attention back to conventional superconductors whose properties can be described by the Bardeen-Cooper-Schrieffer (BCS) and the Migdal-Eliashberg theories. These theories predict that high, and even room temperature superconductivity (RTSC) is possible in metals possessing certain favorable parameters such as lattice vibrations at high frequencies. However, these general theories do not suffice to predict real superconductors. New superconducting materials can be predicted now with the aid of first principles calculations based on Density Functional Theory (DFT). In particular, the calculations suggested a new family of hydrides possessing a clathrate structure, where the host atom (Ca, Y, La) is at the center of the cage formed by hydrogen atoms. For LaH10 and YH10 superconductivity, with critical temperatures Tc ranging between 240 and 320 K is predicted at megabar pressures. Here, we report superconductivity with a record Tc ~ 250 K within the Fm-3m structure of LaH10 at a pressure P ~ 170 GPa. We proved the existence of superconductivity at 250 K through the observation of zero-resistance, isotope effect, and the decrease of Tc under an external magnetic field, which suggests an upper critical magnetic field of 120 T at zero-temperature. The pressure dependence of the transition temperatures Tc (P) has a maximum of 250-252 K at the pressure of about 170 GPa. This leap, by ~ 50 K, from the previous Tc record of 203 K indicates the real possibility of achieving RTSC (that is at 273 K) in the near future at high pressures and the perspective of conventional superconductivity at ambient pressure.

description: We have identified a population of blank field sources (or `blanks') among the ROSAT bright unidentified X-ray sources with faint optical counterparts. The extreme X-ray over optical flux ratio of blanks is not compatible with the main classes of X-ray emitters except for extreme BL Lacertae objects. From the analysis of ROSAT archival data we found no indication of variability and evidence for only three sources, out of 16, needing absorption in excess of the Galactic value. We also found evidence for an extended nature for only one of the 5 blanks with a serendipitous HRI detection; this source (1WGAJ1226.9+3332) was confirmed as a z=0.89 cluster of galaxies. Palomar images reveal the presence of a red (O-E~2) counterpart in the X-ray error circle for 6 blanks. The identification process brought to the discovery of another high z cluster of galaxies, one (possibly extreme) BL Lac, two ultraluminous X-ray sources in nearby galaxies and two apparently normal type1 AGNs. These AGNs, together with 4 more AGN-like objects seem to form a well defined group: they present unabsorbed X-ray spectra but red Palomar counterparts. We discuss the possible explanations for the discrepancy between the X-ray and optical data, among which: a suppressed big blue bump emission, an extreme dust to gas (~40-60 the Galactic ratio), a high redshift (z>3.5) QSO nature, an atypical dust grain size distribution and a dusty warm absorber. These AGN-like blanks seem to be the bright (and easier to study) analogs of the sources which are found in deep Chandra observations. Three more blanks have a still unknown nature.

A possible way to reconcile long-period precession with vortex pinning in neutron stars

description: We propose a possible way to solve the problem of inconsistency between the neutron star long-period precession and superfluid vortex pinning, which is the basis of the most successful theories of pulsar glitches. We assume that the pinning takes place in the region of the neutron star core, which, being magnetically decoupled, can rotate relative to the crust. In the framework of a simple three-component model we show that these two phenomena can coexist in the same pulsar. Some constraints on the formally introduced interaction coefficients following from observation data are formulated.

Estimating the Signal Reconstruction Error from Threshold-Based Sampling Without Knowing the Original Signal

description: The problem of estimating the accuracy of signal reconstruction from threshold-based sampling, by only taking the sampling output into account, is addressed. The approach is based on re-sampling the reconstructed signal and the application of a distance measure in the output space which satisfies the condition of quasi-isometry. The quasi-isometry property allows to estimate the reconstruction accuracy from the matching accuracy between the sign sequences resulting from sampling and the re-sampling after reconstruction. This approach is exemplified by means of leaky integrate-and-fire. It is shown that this approach can be used for parameter tuning for optimizing the reconstruction accuracy.

description: A new technique permits high fidelity measurement of the tunneling density of states (TDOS) of the two-dimensional electron gas. The obtained TDOS contains no distortions arising from low 2D in-plane conductivity and includes the contribution from localized tunneling sites. In a perpendicular magnetic field, a pseudogap develops in the TDOS at the Fermi level. Improved sensitivity enables resolution of a linear dependence of the TDOS on energy near the Fermi energy. The slopes of this linear gap are strongly field dependent. The data are suggestive of a new model of the gap at low energies.

description: Engineering design via CAD software relies on Non-Uniform Rational B-Splines (NURBS) as a means for representing and communicating geometry. Therefore, in general, a NURBS description of a given design can be considered the exact description. The development of isogeometric methods has made the geometry available to analysis methods Hughes et al. (2005). Isogeometric analysis has been particularly successful in structural analysis; one reason being the wide-spread use of two-dimensional finite elements in this field. For fluid dynamics, where three-dimensional analysis is usually indispensable, isogeometric methods are more complicated, yet of course not impossible, to apply in a general fashion. This paper describes a method that enables the solution of fluid-structure interaction with a matching spline description of the interface. On the structural side, the spline is used in an isogeometric setting. On the fluid side, the same spline is used in the framework of a NURBS-enhanced finite element method (extension of Sevilla et al. (2011)). The coupling of the structural and the fluid solution is greatly facilitated by the common spline interface. The use of the identical spline representation for both sides permits a direct transfer of the necessary quantities, all the while still allowing an adjusted, individual refinement level for both sides.

Potential of nonlocally filtered pursuit monostatic TanDEM-X data for coastline detection

description: This article investigates the potential of nonlocally filtered pursuit monostatic TanDEM-X data for coastline detection in comparison to conventional TanDEM-X data, i.e. image pairs acquired in repeat-pass or bistatic mode. For this task, an unsupervised coastline detection procedure based on scale-space representations and K-medians clustering as well as morphological image post-processing is proposed. Since this procedure exploits a clear discriminability of "dark" and "bright" appearances of water and land surfaces, respectively, in both SAR amplitude and coherence imagery, TanDEM-X InSAR data acquired in pursuit monostatic mode is expected to provide a promising benefit. In addition, we investigate the benefit introduced by a utilization of a non-local InSAR filter for amplitude denoising and coherence estimation instead of a conventional box-car filter. Experiments carried out on real TanDEM-X pursuit monostatic data confirm our expectations and illustrate the advantage of the employed data configuration over conventional TanDEM-X products for automatic coastline detection.
