The concerns and coping strategies of new mothers in the early postpartum period
Creators: name: Cadman, Laurie Elizabeth
Publisher: name: University of British Columbia
Year: 2009

description: This study explores the concerns and coping strategies of primiparous women during the first one to four weeks following the birth of their baby. A total of 15 English speaking women between the ages of 22 to 34 were interviewed in their homes. Each woman was asked to describe the current changes, challenges, and joys she was experiencing as well as the coping strategies she was using to deal with the changes, challenges, and joys. A descriptive design was used. Data were collected during interviews using open-ended questions. Inductive content analysis was used to analyze the findings. Six concerns (changes, challenges, and joys) emerged from data collected during interviews: becoming a mother, emotional and physical restoration, breastfeeding, balancing roles, developing relationship with baby, and unsupportive attitudes/actions of others. The eight coping strategies used by the women to manage their concerns were: seeking support/advice, accepting support/advice, caring for self, redefining normal, encouraging/accepting partner's involvement, sharing feelings, identifying what was right for self, and utilizing/modifying former coping strategies. The implications from this research are many. Nurses and childbirth educators need to incorporate specific skills and strategies to deal with the postnatal period in prenatal preparation. Prenatal classes, drop-ins, and information kiosks could serve as a source of information about community resources and how to access them. Alternatively, classes could be offered in the postnatal period. Because breastfeeding issues were such a concern to the women of this study, health care professionals must not stand in judgment of women who wish to bottlefeed from birth, or women who want to switch from breastfeeding to bottlefeeding. Communication between hospital maternity nurses, liaison nurses, and community health nurses needs to be further developed, because community health nurses need to be aware of parental concerns expressed about the postpartum period before they visit parents at home. Nurses, students, and educators must be aware of new mother's concerns during the early postpartum period in order that they can acknowledge, be sensitive to, and respond to these women and their partners appropriately. Nurses need to be involved in the development and operation of programs that are supportive of new parent's concerns and coping strategies. Students, nurses, educators, and researchers also require education about the concerns and coping strategies of new mothers and their partners in order that they support strategies, they assist with development and utilization of strategies and they address their interventions to strategies used by couples.

description: In prior work, {\it Chandra} and Gemini-North observations of the eclipsing X-ray binary M33 X-7 have yielded measurements of the mass of its black hole primary and the system's orbital inclination angle of unprecedented accuracy. Likewise, the distance to the binary is known to a few percent. In an analysis based on these precise results, fifteen {\it Chandra} and {\it XMM-Newton} X-ray spectra, and our fully relativistic accretion disk model, we find that the dimensionless spin parameter of the black hole primary is $a_* = 0.77 \pm 0.05$. The quoted 1-$σ$ error includes all sources of observational uncertainty. Four {\it Chandra} spectra of the highest quality, which were obtained over a span of several years, all lead to the same estimate of spin to within statistical errors (2%), and this estimate is confirmed by 11 spectra of lower quality. There are two remaining uncertainties: (1) the validity of the relativistic model used to analyze the observations, which is being addressed in ongoing theoretical work; and (2) our assumption that the black hole spin is approximately aligned with the angular momentum vector of the binary, which can be addressed by a future X-ray polarimetry mission.
description: 14 pages, 3 figures, 1 table, published in ApJ Letters; as explained in the erratum at the end of the text, the spin parameter has been corrected upward from a*=0.77 to a*=0.84. Apart from the addition of the erratum, the paper is unchanged.

description: Classification problems using deep learning have been shown to have a high-curvature subspace in the loss landscape equal in dimension to the number of classes. Moreover, this subspace corresponds to the subspace spanned by the logit gradients for each class. An obvious strategy to speed up optimisation would be to use Newton's method in the high-curvature subspace and stochastic gradient descent in the co-space. We show that a naive implementation actually slows down convergence and we speculate why this might be.

description: Radio campaigns using maser stellar beacons have provided crucial information to characterize Galactic stellar populations. Currently, the Bulge Asymmetries and Dynamical Evolution (BAaDE) project is surveying infrared (IR) color-selected targets for SiO masers. This provides a sample of evolved stars that can be used to study the inner, optically obscured Galaxy using line of sight velocities and possibly VLBI proper motions. In order to use the BAaDE sample for kinematic studies, the stellar population should be characterized. In this study, the BAaDE targets have been cross-matched with IR (2MASS) and optical Gaia samples. By exploring the synergies of this cross-match together with Gaia parallaxes and extinction maps, the local ($d < 2$ kpc) AGB stars can be characterized. We have defined a \textit{BAaDE-Gaia} sample of 20,111 sources resulting from cross-matching BAaDE targets with IR and optical surveys. From this sample, a~{\local} sample of 1,812 evolved stars with accurate parallax measurements, confirmed evolved stellar evolution stage, and within 2 kpc distance around the Sun was selected, for which absolute (bolometric) magnitudes are estimated. The evolved stellar population with Gaia counterparts that are variable seems to be predominantly associated with AGB stars with moderate luminosity ($1,500^{+3,000}_{-500} \ L_\odot$) and periods between 250 and 1,250 days.

description: The UNISECO project aims to provide recommendations on how the sustainability of agro-ecological farming systems (AEFS) in Europe can be promoted. These recommendations build also upon model-based upscaling to territorial level of case-study based results on various AEFS throughout the partner countries. This deliverable in detail describes the models to do this upscaling, starting with the general context, the description of the conceptual aspects of the mass- and nutrient-flow modelling as used in UNISECO, and then the detailed description of the two biophysical models employed for this.

description: The DC and AC conductivities of the n-GaAs/AlAs heterostructure with two filled size quantization levels are studied within a wide magnetic field range. The electron spectrum of such heterostructure is characterized by two subbands (symmetric $S$ and antisymmetric $AS$), separated by the band gap $Δ_{12}=15.5$ meV. It is shown that, in the linear regime at the applied magnetic field $B >3$ T, the system exhibits oscillations corresponding to the integer quantum Hall effect. A quite complicated pattern of such oscillations is well interpreted in terms of transitions between Landau levels related to different subbands. At $B <1$ T, magneto-intersubband resistance oscillations (MISOs) are observed. An increase in the conductivity with the electric current flowing across the sample or in the intensity of the surface acoustic wave (SAW) in the regime of the integer quantum Hall effect is determined by an increase in the electron gas temperature. In the case of intersubband transitions, it is found that nonlinearity cannot be explained by heating. At the same time, the decrease in the AC conductivity with increasing SAW electric field is independent of frequency, but the corresponding behavior does not coincide with that corresponding to the dependence of the DC conductivity on the Hall voltage $E_y$.

description: We report a theoretical overview of the magnetic domain wall behavior under an electric current in infinitely-long nanotubes with azimuthal magnetization, combining the $1$D analytic model and micromagnetic simulations. We highlight effects that, besides spin-transfer torques already largely understood in flat strips, arise specifically in the tubular geometry: the \OErsted field and curvature-induced magnetic anisotropy resulting both from exchange and material growth. Depending on both the geometry of the tube and the strength of the azimuthal anisotropy, Bloch or Néel walls arise at rest, resulting in two regimes of motion largely dominated by either spin-transfer torques or the \OErsted field. We determine the Walker breakdown current in all cases, and highlight the most suitable parameters to achieve high domain wall speed.

description: We present a homogeneous set of stellar atmospheric parameters Teff, log g, [Fe/H] for MILES, a new spectral stellar library covering the range 3525 - 7500 angstrom at 2.3 angstrom (FWHM) spectral resolution. The library consists of 985 stars spanning a large range in atmospheric parameters, from super metal-rich, cool stars to hot, metal-poor stars. The spectral resolution, spectral type coverage and number of stars represent a substantial improvement over previous libraries used in population synthesis models. The atmospheric parameters that we present here are the result of a previous, extensive compilation from the literature. In order to construct a homogeneous dataset of atmospheric parameters we have taken the sample of stars of Soubiran, Katz & Cayrel, which has very well determined fundamental parameters, as the standard reference system for our field stars, and have calibrated and bootstrapped the data from other papers against it. The atmospheric parameters for our cluster stars have also been revised and updated according to recent metallicity scales, colour-temperature relations and improved set of isochrones.

description: We investigate the attractor mechanism for spherically symmetric extremal black holes in a theory of general $R^2$ gravity in 4-dimensions, coupled to gauge fields and moduli fields. For the general $R^2$ theory, we look for solutions which are analytic near the horizon, show that they exist and enjoy the attractor behavior. The attractor point is determined by extremization of an effective potential at the horizon. This analysis includes the backreaction and supports the validity of non-supersymmetric attractors in the presence of higher derivative interactions. To include a wider class of solutions, we continue our analysis for the specific case of a Gauss-Bonnet theory which is non-topological, due to the coupling of Gauss-Bonnet terms to the moduli fields. We find that the regularity of moduli fields at the horizon is sufficient for attractor behavior. For the non-analytic sector, this regularity condition in turns implies the minimality of the effective potential at the attractor point.

What if you are managed by the algorithm? Effects of trust in and knowledge of a ride-hailing platform on drivers’ job performance through a social exchange perspective
Creators: name: Zhang, Bulin
Publisher: name: No Publisher Supplied
Year: 2023

description: A ride-hailing platform has revolutionized how services are conducted and exchanged in the taxi industry. With technology and customers replacing supervisory control, the ride-hailing work is unique in terms of having multiple partners interacting with each other for value proposition. With a multi-party characteristic identified, I argue that some of the previous research is limited in terms of its emphasis on dyadic exchanges or a discussion focused on the sole function of the platform without integration. As such, it’s still unclear how a platform has transformed and thus impacted our understanding of work exchanges in the ride-hailing work. To address this question, by integrating generalized exchange theory (e.g., Bearman, 1997) with studies of platform work, I propose that ride-hailing services can be best characterized as a triangular exchange mediated by platform technology. Although this type of work has been promoted to enhance work efficiency (Mäntymäki et al., 2019), it brings risks of non-indirect reciprocity and opportunities of free riding to drivers. To address these concerns, I argue that drivers can either trust a platform’s governance of the multilateral exchange or take strategies to combat information asymmetry by gaining knowledge of the platform. By doing so, drivers’ perceptions of a multi-party psychological contract violation can be affected, which, in turn, determines their job performance. To test my hypotheses, I conducted a field investigation using objective performance data obtained from organizational archives and survey data collected from 341 ride-hailing drivers over a 4-month period. My results provide some support for my predictions. I discuss theoretical and practical implications, limitations, as well as future directions.

description: Time crystals, a unique non-equilibrium quantum phenomenon with promising applications in current quantum technologies, mark a significant advance in quantum mechanics. Although traditionally studied in atom-cavity and optical lattice systems, pursuing alternative nanoscale platforms for time crystals is crucial. Here we theoretically predict discrete time-crystals in a periodically driven molecular magnet array, modeled by a spin-S Heisenberg Hamiltonian with significant quadratic anisotropy, taken with realistic and experimentally relevant physical parameters. Surprisingly, we find that the time-crystal response frequency correlates with the energy levels of the individual magnets and is essentially independent of the exchange coupling. The latter is unexpectedly manifested through a pulse-like oscillation in the magnetization envelope, signaling a many-body response. These results show that molecular magnets can be a rich platform for studying time-crystalline behavior and possibly other out-of-equilibrium quantum many-body dynamics.

Forfeiting legal fees with proceeds of crime: the ability of accused persons to pay ’reasonable legal fees’ out of alleged proceeds of crime
Creators: name: Rose, Gregory John
Publisher: name: University of British Columbia
Year: 2009

description: The Canadian proceeds of crime provisions, Part XTJ.2 of the Criminal Code, are targeted at enterprises that are motivated by the desire to generate profit and accumulate wealth from criminal activity. The main purpose of Part XII.2 is to provide the police and prosecution with powerful new tools to attach the proceeds of crime, and the courts with the power to forfeit such proceeds. This thesis will examine how, in recognition of the procedural and substantive problems with this legislation and in contrast to American legislation, Parliament included numerous provisions to balance such extensive powers. The balancing mechanisms included a provision that allows reasonable legal fees to be paid out of seized or restrained property that is alleged to be proceeds and another that requires an in camera session to be held without the presence of the Attorney General, to determine the reasonableness of such fees. The Parliamentary record explicitly demonstrates that the balancing provisions were meant to ensure that the pre-trial restraint and potential forfeiture of property would withstand Charter challenges, especially with regard to an accused's rights to counsel, fair trial and full answer and defence. In this thesis I will analyze the complexities of proceeds litigation and demonstrate how this necessitates adequate legal representation to ensure that an accused's Charter rights are protected. This thesis explores in depth how Parliament recognized the need for balancing mechanisms that permit funds to be released for an accused to retain private counsel. However, these mechanisms have been significantly narrowed by subsequent judicial interpretation. A result of this line of authority is that defence work in the proceeds area has become very difficult. If reasonable legal fees are not taken from seized proceeds, provincial legal aid plans will have to provide for appropriate counsel. This may not be a realistic option given the funding of these plans and their stated objection to funding proceeds cases. Therefore, in this thesis I will argue that if private counsel must be retained the right to counsel could be effectively forfeited, unless a portion of the seized or restrained assets are released for reasonable legal fees. This thesis will attempt to provide a coherent basis for future interpretation of the Part XII.2 provisions that affect legal fees. The approach taken will incorporate the competing interests of accused persons and the State without undermining the objectives of the legislation. This thesis will focus on Canadian legislation and jurisprudence, but will also have a comparative component that examines how these issues have been dealt with in Australia, England and the United States.
Forward modeling the multiwavelength properties of Active Galactic Nuclei: application to X-ray and WISE mid-infrared samples

description: An empirical forward-modeling framework is developed to interpret the multiwavelength properties of Active Galactic Nuclei (AGN) and provide insights into the overlap and incompleteness of samples selected at different parts of the electromagnetic spectrum. The core of the model are observationally derived probabilites on the occupation of galaxies by X-ray selected AGN. These are used to seed mock galaxies drawn from stellar-mass functions with accretion events and then associate them with spectral energy distributions that describe both the stellar and AGN emission components. This approach is used to study the complementarity between X-ray and WISE mid-infrared AGN selection methods. We first show that the basic observational properties of the X-ray and WISE AGN (magnitude, redshift distributions) are adequately reproduced by the model. We then infer the level of contamination of the WISE selection and show that this is dominated by non-AGN at redshifts z < 0.5. These are star-forming galaxies that scatter into the WISE AGN selection wedge because of photometric uncertainties affecting their colours. Our baseline model shows a sharp drop in the number density of heavily obscured AGN above the Compton thick limit in the WISE bands. The model also overpredicts by a factor of 1.5 the fraction of X-ray associations in the WISE AGN selection box compared to observations. This suggests a population of X-ray faint sources that is not reproduced by the model. This discrepancy is discussed in the context of either heavily obscured or intrinsically X-ray weak AGN. Evidence is found in favour of the latter.

Using the low energy effective actions in both $10D$ and 4D, we find precise agreements with the Bekenstein-Hawking entropy of the black hole. We also calculate the higher order corrections to the entropy and find that they depend on the exact form of the higher order corrections to the effective action.

When the surface density profile for member stars with limiting magnitudes of 19.0 in the BATC $e$ band ($λ_{\textrm{eff}}=4925$ Å) is fitted by King model, the core radius $R_{c}=7.52\arcmin$ and the tidal radius $R_{t}=28.84\arcmin$ are derived for NGC 7789. The observed mass function (MF) for main sequence stars of NGC 7789 with masses from 0.95 to 1.85 $M_{\odot}$ is fitted with a power-law function $ϕ(m)\propto m^α$ and the slope $α=-0.96$ is derived. Strong mass segregation in NGC 7789 is reflected in the significant variation of the concentration parameters $C_{0}=\log (R_{t}/R_{c})$ for member stars of NGC 7789 within different mass ranges: $C_{0}=1.02$ for most of massive stars; $C_{0}=0.37$ for the lowest-mass MS stars. Strong mass segregation in NGC 7789 is also indicated in the significant variation of the slopes $α$ in different spatial regions of the cluster: the MF for stars within the core region has $α=-0.71$, much flatter than that for stars in external regions of the cluster ($α=-1.20$).

description: It is known that the operads of perm algebras and pre-Lie algebras are the Koszul dual each other and hence there is a Lie algebra structure on the tensor product of a perm algebra and a pre-Lie algebra. Conversely, we construct a special perm algebra structure and a special pre-Lie algebra structure on the vector space of Laurent polynomials such that the tensor product with a pre-Lie algebra and a perm algebra being a Lie algebra structure characterizes the pre-Lie algebra and the perm algebra respectively. This is called the affinization of a pre-Lie algebra and a perm algebra respectively. Furthermore we extend such correspondences to the context of bialgebras, that is, there is a bialgebra structure for a perm algebra or a pre-Lie algebra which could be characterized by the fact that its affinization by a quadratic pre-Lie algebra or a quadratic perm algebra respectively gives an infinite-dimensional Lie bialgebra. In the case of perm algebras, the corresponding bialgebra structure is called a perm bialgebra, which can be independently characterized by a Manin triple of perm algebras as well as a matched pair of perm algebras. The notion of the perm Yang-Baxter equation is introduced, whose symmetric solutions give rise to perm bialgebras. There is a correspondence between symmetric solutions of the perm Yang-Baxter equation in perm algebras and certain skew-symmetric solutions of the classical Yang-Baxter equation in the infinite-dimensional Lie algebras induced from the perm algebras. In the case of pre-Lie algebras, the corresponding bialgebra structure is a pre-Lie bialgebra which is well-constructed. The similar correspondences for the related structures are given.

description: The atomic-level control achievable in artificially-structured oxide superlattices provides a unique opportunity to explore interface phases of matter including high-density 2D electron gases. Electronic-structure calculations show that the charge distribution of the 2D gas is strongly modulated by electron-phonon interactions with significant ionic polarization. Anharmonic finite-temperature effects must be included to reproduce experiment. Density functional perturbation theory is used to parameterize a simple model introduced to represent these effects and predict temperature dependencies.

Electrostatic effects and topological superconductivity in semiconductor-superconductor-magnetic insulator hybrid wires

description: We investigate the impact of electrostatics on the proximity effect between a magnetic insulator and a semiconductor wire in semiconductor-superconductor-magnetic insulator hybrid structures. By performing self-consistent Schr$\ddot{\rm o}$dinger-Poisson calculations using an effective model of the hybrid system, we find that large effective Zeeman fields consistent with the emergence of topological superconductivity emerge within a large parameter window in wires with overlapping layers of magnetic insulator and superconductor, but not in non-overlapping structures. We show that this behavior is essentially the result of electrostatic effects determining the amplitude of the low-energy wave functions near the semiconductor-magnetic insulator interface.

description: We study the extent to which spin assignments of new particles produced at the LHC can be deduced in the decay of a scalar or fermion C into a new stable (or quasi-stable) particle A through the chain C \to B^\pm q, B^\pm \to A W^\pm, W^\pm \to \ell^\pm ν_\ell where \ell=e,μ. All possible spin assignments of the particles A and B are considered in order to remain as model-independent as possible. Explicit invariant mass distributions of the quark and lepton are given for each set of spins, valid for all masses. We also construct the asymmetry between the chains with a W- and those with a W+. The Kullback-Leibler distance between the distributions is then calculated to give a quantitative measure of our ability to distinguish the different spin assignments.

description: Finite-part integration is a recently introduced method of evaluating convergent integrals by means of the finite part of divergent integrals [E.A. Galapon, {\it Proc. R. Soc. A 473, 20160567} (2017)]. Current application of the method involves exact and asymptotic evaluation of the generalized Stieltjes transform $\int_0^a f(x)/(ω+ x)^ρ \, \mathrm{d}x$ under the assumption that the extension of $f(x)$ in the complex plane is entire. In this paper, the method is elaborated further and extended to accommodate the presence of competing singularities of the complex extension of $f(x)$. Finite part integration is then applied to derive consequences of known Stieltjes integral representations of the Gauss function and the generalized hypergeometric function which involve Stieltjes transforms of functions with complex extensions having singularities in the complex plane. Transformation equations for the Gauss function are obtained from which known transformation equations are shown to follow. Also, building on the results for the Gauss function, transformation equations involving the generalized hypergeometric function $\,_3F_2$ are derived.

description: Manipulating fragile objects in environments such as homes and factories requires stable and gentle grasping along with precise and safe placement. Compared to traditional rigid grippers, the use of soft grippers reduces the control complexity and the risk of damaging objects. However, it is challenging to integrate camera-based optical tactile sensing into a soft gripper without compromising the flexibility and adaptability of the fingers, while also ensuring that the precision of tactile perception remains unaffected by passive deformations of the soft structure during object contact. In this paper, we demonstrate a modular soft two-fingered gripper with a 3D-printed optical tactile sensor (the TacTip) integrated in the palm. We propose a soft-grasping strategy that includes three functions: light contact detection, grasp pose adjustment and loss-of-contact detection, so that objects of different shapes and sizes can be grasped stably and placed precisely, which we test with both artificial and household objects. By sequentially implementing these three functions, the grasp success rate progressively improves from 45% without any functions, to 59% with light contact detection, 90% with grasp pose adjustment, and 97% with loss-of-contact detection, achieving a sub-millimeter placement precision. Overall, this work demonstrates the feasibility and utility of integrating optical tactile sensors into the palm of a soft gripper, of applicability to various types of soft manipulators. The proposed grasping strategy has potential applications in areas such as fragile product processing and home assistance.
Exclusive $B \to PV $ Decays and CP Violation in the General two-Higgs-doublet Model

description: We calculate all the branching ratios and direct CP violations of $B \to PV$ decays in a most general two-Higgs-doublet model with spontaneous CP violation. As the model has rich CP-violating sources, it is shown that the new physics effects to direct CP violations and branching ratios in some channels can be significant when adopting the generalized factorization approach to evaluate the hadronic matrix elements, which provides good signals for probing new physics beyond the SM in the future B experiments.

Commoditization of indigenous cultures through tourism
Creators: name: Karajaoja, Ritva
Publisher: name: University of British Columbia
Year: 2009

description: This essay looks at cultural commoditization by indigenous people in Third World countries in response to tourism. The common assumption is that commoditization invalidates a culture and that it somehow becomes inauthentic. I show that even though the Indians of the Peruvian highlands sell their “Indianess” for tourists to photograph, the real commoditization takes place by mestizos who appropriate Indian culture: their dress, rituals, handicrafts. The Indians and mestizos are both trying to maximize their share of tourism revenue, little of which actually gets to the highlands. Neither culture, however, becomes inauthentic in the process. While the meanings of cultural products may be altered over time, no culture is static and fixed in time: new meanings are relevant within the context of contemporary society.
Semi-regular masas of transfinite length

description: In 1965 Tauer produced a countably infinite family of semi-regular masas in the hyperfinite $\mathrm{II}_1$ factor, no pair of which are conjugate by an automorphism. This was achieved by iterating the process of passing to the algebra generated by the normalisers and, for each $n\in\mathbb N$, finding masas for which this procedure terminates at the $n$-th stage. Such masas are said to have length $n$. In this paper we consider a transfinite version of this idea, giving rise to a notion of ordinal valued length. We show that all countable ordinals arise as lengths of semi-regular masas in the hyperfinite $\mathrm{II}_1$ factor. Furthermore, building on work of Jones and Popa, we obtain all possible combinations of regular inclusions of irreducible subfactors in the normalising tower.
