The married woman in employment -- an exploratory study of how her employment affects the woman, and her relationship with her family, and the community.
Creators: name: Bardal, Margret Stefania
Publisher: name: University of British Columbia
Year: 2012

description: The proportion of women in the Canadian labour force has grown steadily in recent decades. Many of these, however, are younger women who retire from gainful employment after marriage. Married women who work are a special section of the population; they have been the subject of social studies in several countries, but not so far in Canada. This thesis is a supplementary study, influenced by the national survey of married women who are gainfully employed now being undertaken (1956) by the Women's Bureau of the Canadian Department of Labour. The facts reviewed in this present report are obtained from only fifty of the women Interviewed in one of the sample cities (Vancouver); but the opportunity has been taken to make them the basis of all the pros and cons of the situation, including the reasons for working, the types of work, and the effects on family life. The schedule used for the interviews is a standardized, comprehensive one worked out with the assistance of a national advisory committee including the research directors of the Schools of Social Work in Canada. Only a minimum of statistical tabulation is undertaken for this limited sample; a few other schedules obtained from university students were added, and there is no intention to present the information as statistically representative. A systematic review of the qualitative material is attempted, however, to illustrate the differentials which must be considered in a definitive assessment. After experiment with other classifications, it was found most effective to distinguish three main groups (a) families composed of husband and wife without children (or younger dependents); (b) "complete" families with husband and wife and children in the home, and (c) "broken" families, in which the working mother was a widow, separated or divorced, or with dependent or partially dependent husband. The significance of these differences is readily apparent from the views recorded. It was also apparent that the socio-economic differences associated with different levels of income and grade of work (e.g., professional, clerical, service, factory) are of direct importance in modifying the consequences for the family; but these could only be indicated illustratively. In a final section, an endeavour is made to bring together all provisional findings, distinguishing broadly the implications (a) for the woman as a person and as a marital partner, (b) for the children, and parental aspects of family life, and (c) for the community as a whole.

Developmentalism and disciplinary power: The case of Bangladesh

Subjects: Anthropology of development

description: Over the last fifty years or so, a myriad of strategies and techniques were deployed with a hope of bringing the people of post -colonial and underdeveloped societies under the process of 'normalization', i.e. development, such as was already experienced by the Western industrial societies. In the process of their deployment, three actors - European rational science, local trustees and the masses - emerged within an ideal construct, developmentalism. This thesis, using discourse insight, examines the process of normalization that operated through the execution of developmentalism in a particular country - Bangladesh. The thesis shows that, despite achieving the status of political independence as a nation state, Bangladesh not only remained dependent but also entered into a decisive condition of management and control by this disciplinary power of normalization. This occurred through an acceptance of Western modernity as a truth applicable to all humanity. In concrete terms, the Bangladeshi state actively participated in this project by forming (1) a 'think tank' comprising the planning commission and various research institutions; (2) a huge bureaucracy, both public and private; and (3) a mobilisation of the masses into various cooperatives/collectives. The think tank produced development knowledge by directly appropriating the rationality of Western science and technology. Various development projects produced by the application of this knowledge were then implemented by the bureaucracy at the local level. Unlike under colonial subjugation, the masses were not forced to accept the project, but they were made to conform 'of their own free will'. Regardless of its level of achievement in transforming the lives of poor Bangladeshis in material terms, the project achieved their consent to being ruled by the development elite. Although numerous studies have concluded that most Bangladeshis remained poor (if not worse-off), the trustees or elite of development in Bangladesh managed to change their own fortunes. They gained recognition by intellectually promoting Bangladeshi underdevelopment to the West, keeping themselves personally afloat on Western aid, in luxury. In the end, Western science and rationality are enabling them to remain in power until an alternative--a resistance to this hegemony--can be established.

description: For a complete, smooth toric variety Y, we describe the graded vector space T_Y^1. Furthermore, we show that smooth toric surfaces are unobstructed and that a smooth toric surface is rigid if and only if it is Fano. For a given toric surface we then construct homogeneous deformations by means of Minkowski decompositions of polyhedral subdivisions, compute their images under the Kodaira-Spencer map, and show that they span T_Y^1.

Open cluster survival within the solar circle: Teutsch145 and Teutsch146

description: Teutsch145 and Teutsch146 are shown to be open clusters (OCs) orbiting well inside the Solar circle, a region where several dynamical processes combine to disrupt most OCs on a time-scale of a few 10^8yrs. BVI photometry from the GALILEO telescope is used to investigate the nature and derive the fundamental and structural parameters of the optically faint and poorly-known OCs Teutsch145 and 146. These parameters are computed by means of field-star decontaminated colour-magnitude diagrams (CMDs) and stellar radial density profiles (RDPs). Cluster mass estimates are made based on the intrinsic mass functions (MFs). We derive the ages 200+100-50Myr and 400+/-100Myr, and the distances from the Sun 2.7+/-0.3kpc and 3.8+/-0.2kpc, respectively for Teutsch145 and 146. Their integrated apparent and absolute magnitudes are m_V ~ 12.4, m_V ~ 13.3, M_V ~- 5.6 and M_V ~- 5.3. The MFs (detected for stars with m>1Msun) have slopes similar to Salpeter's IMF. Extrapolated to the H-burning limit, the MFs would produce total stellar masses of ~1400Msun, typical of relatively massive OCs. Both OCs are located deep into the inner Galaxy and close to the Crux-Scutum arm. Since cluster-disruption processes are important, their primordial masses must have been higher than the present-day values. The conspicuous stellar density excess observed in the innermost bin of both RDPs might reflect the dynamical effects induced by a few 10^8yrs of external tidal stress.

description: In the conventional seesaw models of neutrino masses, leptogenesis occurs at a very high scale. Three approaches have been discussed in the literature to lower the scale of leptogenesis: mass degeneracy, hierarchy of couplings and three-body decays. We advocate yet another approach to a testable leptogenesis, whereby the decaying particles could go out of equilibrium at an accessible scale due to kinematics, although their couplings to the decay products are larger for generating a desired CP asymmetry. We demonstrate this new possibility for the testable leptogenesis in a two Higgs doublet model where the neutrino masses originate from a one-loop diagram.

description: We demonstrate that many features ascribed to strong correlation effects in various spectroscopies of the cuprates are captured by a calculation of the self-energy incorporating effects of spin and charge fluctuations. The self energy is calculated over the full doping range from half filling to the overdoped system. In the normal state, the spectral function reveals four subbands: two widely split incoherent bands representing the remnant of the two Hubbard bands, and two additional coherent, spin- and charge-dressed in-gap bands split by a spin-density wave, which collapses in the overdoped regime. The resulting coherent subbands closely resemble our earlier mean-field results. Here we present an overview of the combined results of our mean-field calculations and the newer extensions into the intermediate coupling regime.

description: We construct detour complexes from the BRST quantization of worldline diffeomorphism invariant systems. This yields a method to efficiently extract physical quantum field theories from particle models with first class constraint algebras. As an example, we show how to obtain the Maxwell detour complex by gauging N=2 supersymmetric quantum mechanics in curved space. Then we concentrate on first class algebras belonging to a class of recently introduced orthosymplectic quantum mechanical models and give generating functions for detour complexes describing higher spins of arbitrary symmetry types. The first quantized approach facilitates quantum calculations and we employ it to compute the number of physical degrees of freedom associated to the second quantized, field theoretical actions.

Matched-Filter Design to Improve Self-Interference Cancellation in Full-Duplex Communication Systems

description: A new method for capacity and spectral efficiency increases is a full-duplex (FD) communication, where sending and receiving are done simultaneously. Hence, severe interference leaked from the transmitter to the receiver, which can disrupt the system's operation completely. For interference reduction, the transceiver tries to estimate the interfering symbols to remove their effects. A typical method is to use the Hammerstein model. In this method, nonlinear power amplifier (PA) and multipath channel are modeled with a successive nonlinear system and a finite impulse response (FIR) filter. Then, the model parameters are adjusted, and interference symbols are estimated from the transmitted symbols. In the Hammerstein method, the interference symbols are estimated directly from the transmitted symbols. But practically, the transmitted symbols first pass through the pulse-shaping filter and become a signal. Then, this signal passes through the nonlinear PA and communication channel. Finally, the received signal is filtered by the matched filter (MF) at the receiver and converted to the symbols again. In this procedure, the amplifier and the communication channel affect the transmitted signal directly and distort transmitted symbols indirectly. Therefore, in the practical situation, when we consider the transmitter's pulse-shaping filter and the receiver's MF, the estimated symbols with the Hammerstein method are erroneous. To solve this problem, a new MF at the receiver is proposed and adjusted according to the interfering signal. We have shown that this method is far better than the Hammerstein method.
Aspects of rate and efficiency of gain in beef cattle and heritability estimates

description: Nine purebred Hereford bulls which had been tested for rate and efficiency of gain at the University of British Columbia, were bred to 99 heifers, 11 heifers to each bull, obtained from commercial breeders. Bach of the offspring, a total of 84, was weaned at 400 pounds and then placed on an individual feeding test, using the same feeding schedule and the same concentrate ration as that used for the bulls. At 800 pounds, the animals were slaughtered, rail graded and several carcass measurements were collected. Daily rate of gain and feed efficiency were computed over three periods. The following correlations were calculated: birth weight and daily gain during pre-weaning period; birth weight and daily gain during post-weaning period; daily gain during pre-weaning and post-weaning period; daily gain during post-weaning period and percentage lean in ribcut; daily gain during post-weaning period and carcass grade. The "r" value of each of the above calculations was found to be "low". There was a very high correlation between rate and efficiency of gain for each of the three periods: 400 - 800 pounds, r = -0.98 400 - 600 pounds, r = -0.97 600 - 800 pounds, r = -0.98 A simple plan for home testing was outlined. This plan calls for selection on the basis of rate of gain during a test period of approximately 5 months. Animals enter the test period in groups with equal body weight and are full fed.

description: We propose a scheme for efficient cavity-enhanced nonlinear THz generation via difference-frequency generation (DFG) processes using a triply resonant system based on photonic crystal cavities. We show that high nonlinear overlap can be achieved by coupling a THz cavity to a doubly-resonant, dual-polarization near-infrared (e.g. telecom band) photonic-crystal nanobeam cavity, allowing the mixing of three mutually orthogonal fundamental cavity modes through a chi(2) nonlinearity. We demonstrate through coupled-mode theory that complete depletion of the pump frequency - i.e., quantum-limited conversion - is possible in an experimentally feasible geometry, with the operating output power at the point of optimal total conversion efficiency adjustable by varying the mode quality (Q) factors.

description: The one-pion exchange current corrections to isoscalar and isovector magnetic moments of double-closed shell nuclei plus and minus one nucleon with $A=15,17,39$ and 41 have been studied in the relativistic mean field (RMF) theory and compared with previous relativistic and non-relativistic results. It has been found that the one-pion exchange current gives a negligible contribution to the isoscalar magnetic moments but a significant correction to the isovector ones. However, the one-pion exchange current doesn't improve the description of nuclear isovector magnetic moments for the concerned nuclei.

The BEM and DRBEM schemes for the numerical solution of the two-dimensional time-fractional diffusion-wave equations
Creators: name: Alipour, Peyman
Publisher: name: arXiv
Year: 2023
Subjects: subject: Numerical Analysis (math.NA)
subject: FOS: Mathematics

description: In this paper we apply the boundary elements method (BEM) and the dual reciprocity boundary elements method (DRBEM) for the numerical solution of two-dimensional time-fractional partial differential equations (TFPDEs). The fractional derivative of problem is described in the Caputo sense. In BEM, the main equation deduces to solving the Helmholtz equation in each time step. Therefore, we should compute the domain integral in each time step. So, we presented an approach to compute the domain integral with no singularity. On the other hand the DRBEM has the flexibility of discretizing only the boundary of the computational domain and evaluates the solution at any required interior point. We employ the radial basis functions (RBFs) for interpolation of the inhomogeneous and time derivative terms. The proposed method is employed for solving some problems in two--dimensions on unit square and some other complex regions to demonstrate the efficiency of the proposed method.
Distortion in metric matching with ordinal preferences

description: Suppose that we have $n$ agents and $n$ items which lie in a shared metric space. We would like to match the agents to items such that the total distance from agents to their matched items is as small as possible. However, instead of having direct access to distances in the metric, we only have each agent's ranking of the items in order of distance. Given this limited information, what is the minimum possible worst-case approximation ratio (known as the distortion) that a matching mechanism can guarantee? Previous work by Caragiannis et al. proved that the (deterministic) Serial Dictatorship mechanism has distortion at most $2^n - 1$. We improve this by providing a simple deterministic mechanism that has distortion $O(n^2)$. We also provide the first nontrivial lower bound on this problem, showing that any matching mechanism (deterministic or randomized) must have worst-case distortion $Ω(\log n)$. In addition to these new bounds, we show that a large class of truthful mechanisms derived from Deferred Acceptance all have worst-case distortion at least $2^n - 1$, and we find an intriguing connection between thin matchings (analogous to the well-known thin trees conjecture) and the distortion gap between deterministic and randomized mechanisms.

description: We analyze a certain class of integral equations related to Marchenko equations and Gel'fand-Levitan equations associated with various systems of ordinary differential operators. When the integral operator is perturbed by a finite-rank perturbation, we explicitly evaluate the change in the solution. We show how this result provides a unified approach to Darboux transformations associated with various systems of ordinary differential operators. We illustrate our theory by deriving the Darboux transformation for the Zakharov-Shabat system and show how the potential and wave function change when a discrete eigenvalue is added to the spectrum.

Evaluation of Coronal and Interplanetary Magnetic Field Extrapolation Using PSP Solar Wind Observation

description: Using solar wind observation near PSP perihelions as constraints, we have investigated the parameters in various PFSS model methods. It's found that the interplanetary magnetic field extrapolation with source surface height $R_\mathrm{SS} = 2\,Rs$ is better than that with $R_\mathrm{SS} = 2.5\,Rs$. HMI and GONG magnetograms show similar performance in the simulation of magnetic field variation, but the former appears to have a slight advantage in reconstruction of intensity while the latter is more adaptable to sparser grids. The finite-difference method of constructing eigenvalue problem for potential field can achieve similar accuracy as analytic method and greatly improve the computational efficiency. MHD modeling performs relatively less well in magnetic field prediction, but it is able to provide rich information about solar-terrestrial space.
Noise-induced escape from bifurcating attractors: Symplectic approach in the weak-noise limit

Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)
subject: FOS: Physical sciences

description: The effect of noise is studied in one-dimensional maps undergoing transcritical, tangent, and pitchfork bifurcations. The attractors of the noiseless map become metastable states in the presence of noise. In the weak-noise limit, a symplectic two-dimensional map is associated with the original one-dimensional map. The consequences of their noninvertibility on the phase-space structures are discussed. Heteroclinic orbits are identified which play a key role in the determination of the escape rates from the metastable states. Near bifurcations, the critical slowing down justifies the use of a continuous-time approximation replacing maps by flows, which allows the analytic calculation of the escape rates. This method provides the universal scaling behavior of the escape rates at the bifurcations.

Un potente flusso di gas che si allontana dal buco nero supermassivo nel centro della galassia NGC 5548 alla notevole velocità di 18 milioni di chilometri orari è stato individuato da un team internazionale di ricercatori, tra cui due dell’INAF. La scoperta getta nuova luce riguardo le teorie attuali sul funzionamento dei buchi neri e l’interazione di questi ‘mostri cosmici’ con le galassie che li ospitano
