description: The Philippines is one of the most typhoon prone countries in world (Bankoff, 2003), and its government has invested significantly in data technology which has proven to be critical in planning for climate impact. However, there is conflict as to how this data ought to be interpreted and used by the technoscientific community on one hand and, on the other, by sectors of society who rely on traditional and embodied knowledge of the natural environment. How do we interpret the information equitably to make decisions that can protect lives, natural and artificial resources, and livelihoods? We take artist Angelo Vermeulen’s notion of a multispecies roundtable for co-creating systems —in which plants, computers, and people are brought together in mutually beneficial ways (Vermeulen, 2016)—and apply it to the context of natural disaster management. Based on our previous experience working in post-disaster reconstruction and design (Cajilig & Salva, 2014), we propose a design concept to integrate ethnoscientific models for weather and climate prediction by indigenous and artisanal groups.

description: Hyperuniform states of matter are characterized by anomalous suppression of long-wavelength density fluctuations. While most of interesting cases of disordered hyperuniformity are provided by complex many-body systems like liquids or amorphous solids, classical spin chains with certain long-range interactions have been shown to demonstrate the same phenomenon. It is well-known that the transverse field Ising model shows a quantum phase transition (QPT) at zero temperature. Under the quantum effects of a transverse magnetic field, classical hyperuniform spin chains are expected to lose their hyperuniformity. High-precision simulations of these cases are complicated because of the presence of highly nontrivial long-range interactions. We perform extensive analysis of these systems using density matrix renormalization group to study the possibilities of phase transitions and the mechanism by which they lose hyperuniformity. We discover first-order QPTs in the hyperuniform spin chains. An interesting feature of the phase transitions in these disordered hyperuniform spin chains is that, depending on the parameter values, the presence of transverse magnetic field may remarkably lead to increase in the order of the ground state as measured by the "$τ$ order metric," even if hyperuniformity is lost. Therefore, it would be possible to design materials to target specific novel quantum behaviors in the presence of a transverse magnetic field. Our numerical investigations suggest that these spin chains can show no more than two QPTs. We further analyze the long-range interacting spin chains via the Jordan-Wigner mapping, showing that under the pairwise interacting approximation and a mean-field treatment, there can be at most two QPTs. Based on these numerical and theoretical explorations, we conjecture that these spin chains can show a maximum of two QPTs at zero temperature.

description: We investigate thermodynamics of a single classical particle placed in a spherical box of a finite radius $R$ and subject to a superposition of a $N-$dimensional Gaussian random potential and the parabolic potential with the curvature $μ>0$. Earlier solutions of $R\to \infty$ version of this model were based on combining the replica trick with the Gaussian Variational Ansatz (GVA) for free energy, and revealed a possibility of a glassy phase at low temperatures. For a general $R$, we show how to utilize instead the underlying rotational symmetry of the replicated partition function and to arrive to a compact expression for the free energy in the limit $N\to \infty$ directly, without any need for intermediate variational approximations. This method reveals striking similarity with the much-studied spherical model of spin glasses. Depending on the value of $R$ and the three types of disorder - short-ranged, long-ranged, and logarithmic - the phase diagram of the system in the $(μ,T)$ plane undergoes considerable modifications. In the limit of infinite confinement radius our analysis confirms all previous results obtained by GVA.

description: Reinforcement learning deals with the problem of sequential decision making in uncertain stochastic environments. In this thesis I deal with agents who attempt to solve the reinforcement learning problem online and in real-time. This presents experimental challenges for which I introduce novel kernelised algorithms. Kernel algorithms are very useful in reinforcement learning settings as they enable learning in situations where a very high-dimensional or hand engineered feature vector would otherwise be required. Furthermore, I attempt to address the theoretical challenges which arise from online on-policy algorithms, for which I introduce a type of analysis which is novel (and useful) to reinforcement learning in its lack of restrictive assumptions on the behaviour policy. I will introduce three novel algorithms attempting to advance the areas of kernel, empirical and theoretical reinforcement learning. The first of these algorithms presents a kernel extension of SARSA for its empirical properties - namely its incorporation of eligibility traces with sparse kernel algorithms. I then present a model-free/model-based ensemble which use gradient based methods for online learning. I present them with regret analysis which enables an analysis of the value functions learned with no probabilistic assumptions, and hence no assumptions on the behaviour policy. Along the way I also make a novel "sub-contribution", namely non-squared loss functions for reinforcement learning. The use of different loss functions constitutes a running theme through the algorithms I introduce, as I show that various non-traditional (to reinforcement learning) loss functions can be useful for both efficiency of the algorithm, and for accuracy by ensuring smooth function approximations. I present thorough experimental and theoretical analyses along the way.

description: This paper presents a method to register a preoperative CT volume to a sparse set of intraoperative US slices. In the context of percutaneous renal puncture, the aim is to transfer a planning information to an intraoperative coordinate system. The spatial position of the US slices is measured by localizing a calibrated probe. Our method consists in optimizing a rigid 6 degree of freedom (DOF) transform by evaluating at each step the similarity between the set of US images and the CT volume. The images have been preprocessed in order to increase the relationship between CT and US pixels. Correlation Ratio turned out to be the most accurate and appropriate similarity measure to be used in a Powell-Brent minimization scheme. Results are compared to a standard rigid point-to-point registration involving segmentation, and discussed.
Synthetic Approaches to the Macrocyclic Natural Product Tripartilactam

Publisher: name: The Australian National University
Year: 2018

description: In 2012 Oh and co-workers reported the isolation of the tricyclic macrolactam tripartilactam from a Streptomyces sp. found in the brood ball of the dung bettle Copris tripartitus. The compound proved to be a moderate inhibitor of sodium/potasium ATPase. The unique and rather complex structure embodies a cyclobutane fused, on its opposing faces, to both an 8- and an 18-membered ring. These architecturally novel features prompted the author to pursue a total synthesis of it. Chapter One provides a brief introduction to the isolation, structural elucidation and proposed biogenesis of tripartilactam. This section also provides details of selected organic reactions that played important roles in the synthetic studies of the author, in particular the Stille cross-coupling, olefin metathesis and olefination reactions. Chapter Two describes two distinct sets of manipulations of the enantiomerically pure chloro cis-1,2-dihydrocatechol, readily obtained through the whole-cell biotransformation of chlorobenzene, into a terminal allene/carbonyl-conjugated alkene and a polyoxygenated cyclooctenone embodying the Eastern Hemisphere of the non-natural enantiomeric form of tripartilactam. Attempts to elaborate these intermediates to the bicyclo[6.2.0]decane system via both intra- and inter-molecular [2+2]-cycloaddition reactions are also discussed. The research detailed in Chapters Three, Four and Five are focused on the synthesis of a macrolactam that it was thought could engage in a transannular [2+2]-cycloadditon reaction and thus mimicking the final step in the proposed biogenesis of tripartilactam. A macrolactone was identified as a potential precursor to tripartilactam and attempts to prepare the former compound are described in Chapter Six.

description: The present study focused on the effects of trunk extensor muscles fatigue on postural control during quiet standing under different somatosensory conditions from the foot and the ankle. With this aim, 20 young healthy adults were asked to stand as immobile as possible in two conditions of No fatigue and Fatigue of trunk extensor muscles. In Experiment 1 (n = 10), somatosensation from the foot and the ankle was degraded by standing on a foam surface. In Experiment 2 (n = 10), somatosensation from the foot and ankle was facilitated through the increased cutaneous feedback at the foot and ankle provided by strips of athletic tape applied across both ankle joints. The centre of foot pressure displacements (CoP) were recorded using a force platform. The results showed that (1) trunk extensor muscles fatigue increased CoP displacements under normal somatosensatory conditions (Experiment 1 and Experiment 2), (2) this destabilizing effect was exacerbated when somatosensation from the foot and the ankle was degraded (Experiment 1), and (3) this destabilizing effect was mitigated when somatosensation from the foot and the ankle was facilitated (Experiment 2). Altogether, the present findings evidenced re-weighting of sensory cues for controlling posture during quiet standing following trunk extensor muscles fatigue by increasing the reliance on the somatosensory inputs from the foot and the ankle. This could have implications in clinical and rehabilitative areas.

description: We address the issue of endemic electronic inhomogeneities in manganites using extensive simulations on a new model with Coulomb interactions amongst two electronic fluids, one localized (polaronic), the other extended (band-like), and dopant ions. The long range Coulomb interactions frustrate phase separation induced by the strong on site repulsion between the fluids. A single quantum phase ensues which is intrinsically and strongly inhomogeneous at a nano-scale, but homogeneous on meso-scales, with many characteristics (including colossal responses)that agree with experiments. This, we argue, is the origin of nanoscale inhomogeneities in manganites, rather than phase competition and disorder related effects as often proposed.

The impact of organized Christian religion on identity development in adolescents
Creators: name: Gunn, Heather Gordon
Publisher: name: University of British Columbia
Year: 2009

description: A significant number of youth today affiliate with organized Christian religion. This research explores their experiences within that setting, experiences which either facilitated or hindered their identity development. Fifteen participants who were involved in organized Christian religion during their adolescence were interviewed. The critical incident technique was utilized to assess their experiences. 175 critical incidents were identified including 111 positive, or facilitating factors, and 64 negative, or hindering factors. Eight categories emerged from the 175 incidents. These were: 1. Mentors; 2. Inclusivity and Belonging; 3. Challenged to Think for Themselves; 4. Growth Through Success; 5. Given a Choice; 6. Faith Integrated Throughout Life; 7. Having Fun; 8. Family Support. These categories included both positive and negative critical incidents. Several writers identified religion as a significant factor in shaping the identity of both men and women. Some went further and suggested that religious factors are more powerful in relation to identity than any one of the following: occupation, politics, sex-role beliefs and sexual expression. The study explored a range of experiences as indicated above with a view to isolating those positive and negative influences that were determinants in the lives of the fifteen participants. The results of the study confirm both the general assertions, such as those listed above, as well as the more specific claims that are recorded in the literature. Both Shelton (1990) and Erikson (1964) stress the value to adolescents of belonging to a community. It provides security, it is a place where one can explore ideas among peers, and it gives the young person a certain sense of identity by virtue of membership in a particular group. If the group includes adults to whom young people can easily relate, then there is the additional advantage of mentoring, a highly desirable resource for adolescents as Hendry, Roberts, Glendinning, and Coleman (1992) have pointed out. More generally, the literature supports a range of social activities that contribute to identity formation. Among these are the value of having fun, and the need to be free from direction in order to make independent choices, Peters (1992). Furthermore, as Goldman (1965) has shown, these choices need to be exercised in the context of a young person's world view so that thinking about values is not compartmentalized but rather is established in the total life setting.

The Use of Agent-Based Models as Virtual Laboratories for Exploring Human-Environment Interactions in Land-Use Systems

description: Land-cover changes from human land-uses are seen as primary sources of global environmental change. The multitude of forces influencing land change and the complexity of their interactions present substantial challenges for connecting land-use changes to their causes at and between local, regional, and global scales. Due to this complexity, simulation modeling is a primary tool for conceptualizing land-use system structure and testing causal explanations of observed patterns of land changes. Inductive modeling methods, which have been the dominant approach in land change science, have advanced understanding of global patterns and driving forces of land-use and -cover change (LUCC). However, because land-use systems exhibit nonlinear dynamics driven by adaptive responses of human decision-makers, deductive modeling methods that build process-based understanding of land change are also needed. Using two different agent-based models as virtual laboratories, this dissertation explores how individual land users' decision-making processes translate into observed land-use patterns across a spectrum of different land-use systems. The first model represented the decision-making models and interactions of consumer, farmer, and developer agents in land and housing markets in an expanding ex-urban land-use system, which produced development patterns characteristic of 'urban sprawl' from the bottom-up. The same modeling framework was adapted to experimentally test alternative developer decision-making models, and results indicated cognitive biases and credit constraints may lead to inefficient land-use patterns and impediments to adopting ecological subdivision designs. The second model tested mechanistic explanations of empirically-based, system-level patterns of agricultural change due to individual land-user responses to changing environmental, demographic, and economic conditions. Results demonstrated threshold transitions between alternative livelihood strategies defined by interactions between market influence and population pressure. The model was then expanded and applied to a range of real land-use systems. Comparisons across six sites illustrated the varying effects of common processes driving land-use change, and revealed important mechanisms that influenced agents' land-use decisions and resulting patterns of LUCC. Ultimately, agent-based virtual laboratories made explicit and testable connections between individual decision-making processes and system-level patterns of LUCC. I conclude with a synthesis of the insights gained from model experiments, and put forth a framework for a general land systems theory.

description: After a protracted struggle, Maryland's General Assembly granted all white men the right to vote beginning in 1803, overturning the state's old laws, which restricted the franchise to male property owners. The new standards represented a break from the traditional ""Blackstonian"" conception of suffrage, which entrusted the right to vote only to those--property owning men--whose economic independence would enable them to vote responsibly. By enfranchising propertyless men, and disenfranchising property-owning African Americans, Maryland put itself at the fore of a nationwide reexamination of citizenship driven by the nineteenth century's changing socio-economic landscape. Historians studying voting traditionally have minimized reform's effects, depicting it as the inevitable result of efforts to perfect the essentially complete democracy that existed in the United States in the first part of the nineteenth century. These historians have in large part ignored the reality that the right to vote was extend to some, but taken from others. This thesis draws on original poll books, county assessments, and census data from Kent County, Maryland, to examine the extent to which newly-enfranchised voters participated in electoral politics in suffrage reform's first decade. Ultimately, in Kent and similar parts of Maryland, few new voters went to the polls. Except in select areas like Baltimore, electoral politics in Maryland remained largely the province of the wealthy, who continued to dominate the state's government. However, suffrage reform played an important role in revitalizing the spirit of the American Revolution, and set the stage for later reforms during the Jacksonian era.

description: Chronically-ill older adults (age 65+) who receive a new cancer diagnosis face many unique challenges (e.g., medication management, fractioning of care, etc.), yet very little had been known about how this group of individuals understood and attached meaning to their experiences. This qualitative study therefore sought to describe, in part, how chronically ill, older individuals experienced a new cancer diagnosis and the effects this had on their overall healthcare trajectories and notions of personal health, well-being, and life satisfaction. Thus, a series of three, semi-structured interviews was conducted with each of fifteen informants over the course of approximately three weeks. The interviews asked questions that explored each person's life history (Interview One), individual experiences of co-morbid, chronic disease (Interview Two), and direct experiences with cancer and their cancer diagnosis, in particular (Interview Three). The audio-recorded interviews were transcribed for subsequent large-level coding and analyses. Interviews were analyzed thematically to describe how the sample of individuals presented and described the personal meaning of the cancer experience through descriptions of their diagnosis and the events preceding it: the stories of illness, its meaning, and its consequences. In this way, three overarching themes arose from the data: (1) Time in Illness, (2) Meaning of Illness, and (3) Identity as Affected by Illness. There were a variety of subthemes and these are all discussed at length throughout the dissertation. Understanding how each of these areas connects to the illness experience enhances the quality of illness management by eliciting common areas of stress throughout the diagnosis and illness experience for older individuals, particularly in light of multi-morbidity.

description: The strongly correlated two-electron transport in one-dimensional channel coupled with an Anderson-type impurity is solved exactly via a Bethe ansatz approach. We show that the transport properties are fundamentally different for spin singlet and triplet states, thus the impurity acts as a novel filter that operates based on the total spin angular momentum of the electron pairs, but not individual spins. The filter provides a deterministic generation of electron entanglement in spin, as well as energy and momentum space.

description: Magnon transport through a magnetic insulator can be controlled by current-biased heavy-metal gates that modulate the magnon conductivity via the magnon density. Here, we report nonlinear modulation effects in 10$\,$nm thick yttrium iron garnet (YIG) films. The modulation efficiency is larger than 40\%/mA. The spin transport signal at high DC current density (2.2$\times 10^{11}\,$A/m$^{2}$) saturates for a 400$\,$nm wide Pt gate, which indicates that even at high current levels a magnetic instability cannot be reached in spite of the high magnetic quality of the films.

description: We study the quantum phase diagrams of Bose-Fermi mixtures of ultracold atoms confined to one dimension in an optical lattice. For systems with incommensurate densities, various quantum phases, e.g. charge/spin density waves, pairing, phase separation, and the Wigner crystal, are found to be dominant in different parameter regimes within a bosonization approach. The structure of the phase diagram leads us to propose that the system is best understood as a Luttinger liquid of polarons (i.e. atoms of one species surrounded by screening clouds of the other species). Special fillings, half-filling for fermions and unit filling for bosons, and the resulting gapped phases are also discussed, as well as the properties of the polarons and the experimental realization of these phases.

description: Older adults utilize more health care services than various other populations due to the complex nature of their health care needs. As acuity in health conditions increase, experienced care providers such as Certified Nurse Aides (CNAs) will be needed to offer hands-on care including care for the treatment of complex conditions. CNAs are essential caregivers, providing care that directly impacts resident outcomes. CNAs are currently only trained to provide a basic level of care and are not permitted to handle complex care tasks. CNAs do not have a scope of practice but manage care under the guidance of the 42 CFR ? 483. There is not a clear understanding of what are the allowable delegated activities for the CNA beyond that of the basic skills. The variation of allowable care tasks per state may result in confusion of what are the overall CNA job roles or scope.  This dissertation described what are the allowable delegated activities for CNAs working in nursing facility settings. Further, this work determined if there was a difference in the clinical outcomes in states that had a basic versus states that had an expanded scope of practice for CNAs, and this dissertation described the self-efficacy expectations and care tasks performed among CNAs.  Findings suggest that all states within the United States allow CNAs to manage basic care tasks, and 11 states allow CNAs to manage expanded care tasks. Findings also indicate that there was no difference in clinical outcomes, specifically the outcomes of ADLs, falls with major injury, restraint use, and pain when compared to the allowable care tasks managed by CNAs in each state. Finally, CNAs who worked in states that allowed for expanded care tasks had a stronger self-efficacy for performing expanded tasks when compared to CNAs who worked in states that only allow CNAs to manage basic tasks.

description: Firth-type logistic regression has become a standard approach for the analysis of binary outcomes with small samples. Whereas it reduces the bias in maximum likelihood estimates of coefficients, bias towards 1/2 is introduced in the predicted probabilities. The stronger the imbalance of the outcome, the more severe is the bias in the predicted probabilities. We propose two simple modifications of Firth-type logistic regression resulting in unbiased predicted probabilities. The first corrects the predicted probabilities by a post-hoc adjustment of the intercept. The other is based on an alternative formulation of Firth-types estimation as an iterative data augmentation procedure. Our suggested modification consists in introducing an indicator variable which distinguishes between original and pseudo observations in the augmented data. In a comprehensive simulation study these approaches are compared to other attempts to improve predictions based on Firth-type penalization and to other published penalization strategies intended for routine use. For instance, we consider a recently suggested compromise between maximum likelihood and Firth-type logistic regression. Simulation results are scrutinized both with regard to prediction and regression coefficients. Finally, the methods considered are illustrated and compared for a study on arterial closure devices in minimally invasive cardiac surgery.
Variational Principle for Mixed Classical-Quantum Systems

description: An extended variational principle providing the equations of motion for a system consisting of interacting classical, quasiclassical and quantum components is presented, and applied to the model of bilinear coupling. The relevant dynamical variables are expressed in the form of a quantum state vector which includes the action of the classical subsystem in its phase factor. It is shown that the statistical ensemble of Brownian state vectors for a quantum particle in a classical thermal environment can be described by a density matrix evolving according to a nonlinear quantum Fokker-Planck equation. Exact solutions of this equation are obtained for a two-level system in the limit of high temperatures, considering both stationary and nonstationary initial states. A treatment of the common time shared by the quantum system and its classical environment, as a collective variable rather than as a parameter, is presented in the Appendix.

Granice empatii. O napięciu związanym z badaniem biografii komunistów / The borders of empathy. On the tension inherent in the study of communist biographies - VoR

description: The phenomenon that is communism still arouses many emotions. Especially in countries where attempts were made to put its ideas into practice, such as Poland. For this reason, the study of its history – absurd though it may seem – also generates controversy. Of no small importance for the emergence of this situation is the fact that in domestic public discourse anti-communism still plays a major role, as a handy instrument for stigmatising and disciplining political opponents, but also as a signpost for official narratives about Polish history in the 20th century. This has implications for research. Approaches to communist issues in the classical manner – sine ira et studio – are not infrequently misunderstood, most often outside the scholarly circuit, but also in the academic world. Biographies of communists are a particular example, people who are denied positive qualities and motives, and consider attempts to understand their attitudes to make little sense. The text is an authorial reflection, referring to the autoethnographic method, on biographical studies that have been going on for more than two decades and the tensions they create.
Stepmothers’ experiences of achieving satisfactory stepmother-stepdaughter relationships
Creators: name: Howell-Jones, Gail
Publisher: name: University of British Columbia
Year: 2009

description: The stepfamily has always been part of western society. However, only in the past two decades has it been given much attention, and in spite of suggestions that the stepmother-stepdaughter relationship is both the most problematic of step relationships, even contemporary literature virtually ignored it. Using an interview and validation format, this research explored the experiences of 6 stepmothers as they defined and negotiated satisfactory relationships with their stepdaughters. Specifically the researcher interviewed six stepmothers who described themselves as having achieved what they believed to be satisfactory relationships with their stepdaughters. Five themes emerged from these narratives: The ability to balance Emotional and behavioural Distance with Openness, the Ability to Engage in Positive Persistence, the Ability to develop a Unique and valued Role in the Lives of their Stepdaughters, the Need for a Supportive Partner, and the Need to Relax Expectations of Self and Other.

Exceptional Supersymmetric Standard Models with non-Abelian Discrete Family Symmetry

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: We introduce a non-Abelian discrete $Δ_{27}$ family symmetry into the recently proposed classes of Exceptional Supersymmetric Standard Model ($E_6$SSM) based on a broken $E_6$ Grand Unified Theory (GUT) in order to solve the flavour problem in these models and in particular to account for tri-bimaximal neutrino mixing. We consider both the minimal version of the model (the ME$_6$SSM) with gauge coupling unification at the string scale and the E$_6$SSM broken via the Pati-Salam chain with gauge coupling unification at the conventional GUT scale. In both models there are low energy exotic colour triplets with couplings suppressed by the symmetries of the model, including the family symmetry. This leads to suppressed proton decay and long lived TeV mass colour triplet states with striking signatures at the LHC. We also present a dynamical solution to the $μ'$ problem (where $μ'$ is the mass of the additional pair of electroweak doublets in the E$_6$SSM).

description: We have investigated shot noise in a 6-nm-diameter, semiconducting multiwalled carbon nanotube FET at 4.2 K over the frequency range 600 - 950 MHz. We find a transconductance of 3 - 3.5 $μ$S for optimal positive and negative source-drain voltages V. For the gate referred input voltage noise, we obtain 0.2 and 0.3 $μ{V}/ \sqrt{Hz}$ for V>0 and V<0, respectively. As effective charge noise this corresponds to $2-3 \cdot 10^{-5}$ e/$\sqrt{Hz}$.

Adaptive State Fidelity Estimation for Higher Dimensional Bipartite Entanglement

Publisher: name: arXiv
Year: 2020
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: An adaptive method for quantum state fidelity estimation in bipartite higher dimensional systems is established. This method employs state verifier operators which are constructed by local POVM operators and adapted to the measurement statistics in the computational basis. Employing this method, the state verifier operators that stabilize Bell-type entangled states are constructed explicitly. Together with an error operator in the computational basis, one can estimate the lower and upper bounds on the state fidelity for Bell-type entangled states in few measurement configurations. These bounds can be tighter than the fidelity bounds derived in [Bavaresco et.al., Nature Physics (2018), 14, 1032~1037], if one constructs more than one local POVM measurements additional to the measurement in the computational basis.
