description: Motivated by discrete directed polymers in one space and one time dimension, we construct a continuum directed random polymer that is modeled by a continuous path interacting with a space-time white noise. The strength of the interaction is determined by an inverse temperature parameter beta, and for a given beta and realization of the noise the path evolves in a Markovian way. The transition probabilities are determined by solutions to the one-dimensional stochastic heat equation. We show that for all beta > 0 and for almost all realizations of the white noise the path measure has the same Holder continuity and quadratic variation properties as Brownian motion, but that it is actually singular with respect to the standard Wiener measure on C([0,1]).

A Leptonic Model of Steady High-Energy Gamma-Ray Emission from Sgr A$^*$

Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)

description: Recent observations of Sgr A$^*$ by Fermi and HESS have detected steady gamma-ray emission in the GeV and TeV bands. We present a new model to explain the GeV gamma-ray emission by inverse Compton scattering by nonthermal electrons supplied by the NIR/X-ray flares of Sgr A$^*$. The escaping electrons from the flare regions accumulate in a region with a size of $\sim 10^{18}$ cm and magnetic fields of $\lesssim 10^{-4}$ G. Those electrons produce gamma-rays by inverse Compton scattering off soft photons emitted by stars and dust around the central black hole. By fitting the GeV spectrum, we find constraints on the magnetic field and the energy density of optical-UV radiation in the central 1 pc region around the supermassive black hole. While the GeV spectrum is well fitted by our model, the TeV $γ$-rays, whose spectral index is different from that of the GeV emission, may be from different sources such as pulsar wind nebulae.

description: In this paper we discuss the law of variation of scale factor $a = (t^{k}e^{t})^{\frac{1}{n}}$ which yields a time-dependent deceleration parameter (DP) representing a new class of models that generate a transition of universe from the early decelerated phase to the recent accelerating phase. Exact solutions of Einstein's modified field equations with perfect fluid and heat conduction are obtained within the framework of Saez-Ballester scalar-tensor theory of gravitation and the model is found to be in good agreement with recent observations. We find, for n = 3, k = 1, the present value of DP in derived model as q_0 = -0.67 which is very near to the observed value of DP at present epoch. We find that the time-dependent DP is sensible for the present day Universe and give an earmark description of evolution of universe. Some physical and geometric properties of the models are also discussed.

description: We apply Support Vector Machines -- a machine learning algorithm -- to the task of classifying structures in the Interstellar Medium. As a case study, we present a position-position velocity data cube of 12 CO J=3--2 emission towards G16.05-0.57, a supernova remnant that lies behind the M17 molecular cloud. Despite the fact that these two objects partially overlap in position-position-velocity space, the two structures can easily be distinguished by eye based on their distinct morphologies. The Support Vector Machine algorithm is able to infer these morphological distinctions, and associate individual pixels with each object at >90% accuracy. This case study suggests that similar techniques may be applicable to classifying other structures in the ISM -- a task that has thus far proven difficult to automate.

Organoiridium Hydride, Hydroxo, and μ-Oxo Complexes Supported by a New PCP Pincer Ligand Framework

subject: organometallic

description: Increasing energy demand and environmental consequences associated with the combustion of fossil fuels have led a significant portion of the scientific community to focus on the development of renewable energy technologies. With the success demonstrated by the organometallic community in the catalytic transformation of C-H and C-C bonds, this sub-discipline attempts to expand the hydrocarbyl fundamental understanding to O-H and O-O bonds as a potential means of catalyst development for the water splitting reaction. While a number of catalysts have been realized to facilitate this reaction, they perform under highly oxidizing conditions preventing intermediate characterization and thus preclude detailed understanding of the mechanism of metal mediation. Iridium has shown remarkable potential for catalytic water oxidation in a variety of different coordination environments, despite its high price tag. This thesis focussed on the design and development of an ancillary ligand framework, to support iridium in carrying out fundamental O-H bond transformation, namely, a highly electron donating “PCsp3P” or “PCcarbeneP” pincer ligand, which could encourage iridium to undergo oxidative addition of an O-H bond of water. The targeted ligand was bis-(2-(dialkylphosphino)phenyl)methane, which was synthesized and characterized with iso-propyl, cyclohexyl and tert-butyl examples. Complexation with iridium showed “benzylic” bound PCsp3P iridium (III) complexes in addition to “benzylidene” anchored PCcarbeneP iridium (I) species (double C-H activation), which interconvert with the addition or removal of hydrogen. The stability of PCcarbeneP iridium (I) complexes imparted by the ortho-phenylene fused backbone was demonstrated through a variety of substitution reactions resulting in carbon, nitrogen and oxygen ligands bound trans to the anchoring carbene. This family of complexes was employed as precursors to PCsp3P iridium polyhydride complexes with ligand cooperation potential. Furthermore, PCcarbeneP iridium (I) anilido complexes proved to be precursors for 2-electron reductive coupling of acetonitrile and consequently the synthesis of iridium (I) cations, including an aqua-supported example. Finally, the synthesis and examination of PCcarbeneP iridium (I) hydroxo and unusual μ-oxo complexes was performed to gain insight on the hydrolysis of the Ir-O linkage. Ultimately, Ir-O bond cleavage was evidenced to be initiated by protonation of the bridging oxygen atom.

description: While virtual reality applications allow for face-to-face collaboration and the ability to see each other’s avatars, having different graphical viewpoints can hinder task performance due to the confusion caused by left-right ambiguities and text orientation. In this thesis, we investigate the effect of altering collaborators’ viewpoints and sharing one collaborator’s viewpoint with the other without moving the avatars’ positions in a collaboration between two people in Virtual Reality. We created a Virtual Reality application and twelve scenarios to understand this approach’s effect. Two terms were defined: Shared Viewpoint, which is when users’ graphical viewpoints are decoupled from their avatars and put next to each other, and Independent Viewpoint, in which users’ graphical viewpoints are where their avatars are located. A user study is conducted to gather qualitative and quantitative data. We calculated task completion time and users’ preferences when they have a shared graphical viewpoint from the virtual world and object. Our findings showed that users prefer a shared viewpoint rather than independent viewpoints. Additionally, we discovered that having a shared viewpoint can either increase or decrease task completion time, depending on the relative positions of avatars around the table.

sexual coercion

description: Models of sexual conflict over mating, including conflict over indirect benefits of mate choice, have generally presumed that female resistance to male coercion must involve direct confrontation, which can lead to sexually antagonistic co-evolutionary arms-races. We built a quantitative model examining the largely ignored possibility that females may evolve new, additional mate preferences for new male traits that undermine male capacity to coerce. Thus, females may "remodel" the coercive capacity of the male phenotype in order to enhance their own sexual autonomy – a novel alternative mechanism by which females may avoid arms-races. We demonstrate that evolutionary "remodeling" is possible, in spite of costs to males, because females that prefer males with protective, autonomy-enhancing traits (traits correlated with lower coercion effectiveness) are likelier to gain indirect benefits of having attractive mates. Our analysis reveals new possibilities for the evolution of systems of sexual conflict over indirect benefits, showing that autonomy-enhancing male traits can act as a "public good," benefiting all females regardless of mating preferences, leading to oscillatory dynamics; and that preferences for more protective male traits will often be favored relative to preferences for less protective traits, potentially leading to an evolutionary "snowball" of expanding sexual autonomy.

subject: randomized controlled trial

description: Abstract Approximately half of all men treated for prostate cancer (PCa) will undergo androgen deprivation therapy (ADT). Although ADT can substantially slow the progress of PCa and allow men with metastatic disease to live otherwise free of cancer symptoms, ADT is associated with many bothersome side effects which contribute to diminished quality of life (e.g. hot flashes, fatigue, sexual dysfunction). ADT also increases the likelihood that patients will develop significant health risks such as osteoporosis, cardiovascular disease, obesity, and insulin resistance, which can hasten the deaths of PCa patients. Our previous qualitative study demonstrated that patients feel inadequately prepared to cope with the life changing effects of ADT. Thus, we surveyed patients who had recently begun ADT and found significant deficits in their knowledge of ADT side effects. We concluded that their lack of knowledge might partially explain patients’ difficulty in coping with side effects; patients uninformed about side effects do not engage in behaviors to prevent or reduce the risk of adverse effects. We also determined there are great inconsistencies across sources of information on ADT; therefore, we created an educational workbook to teach men what to expect when on ADT and how to manage side effects. Eligible patients (104) and their partners (53) were randomly assigned to receive the educational workbook or usual care. Participants were assessed, throughout their first 6 months on ADT, on side effect knowledge, experience and bother, sexual activity, mood, relational intimacy, and use of ADT side effect management strategies. The educational intervention was found to be both feasible and acceptable; however, there were no significant group differences on outcome measures. Despite improvements in side effect knowledge, patients demonstrated declines in sexual function and relational intimacy, as well as increased bother associated with ADT side effects. While participants reported the workbook to be helpful, the intervention was not sufficient to result in improved outcomes. The intervention may show promise for partners as marginally significant group differences were observed on a measure of relational intimacy. Suggestions for improving efforts to reduce the suffering of men on ADT are offered.

description: Exploring the interaction of light and matter at the ultimate limit of single photons and single emitters is of great interest both from a fundamental point of view and for emerging applications in quantum engineering. However, the difficulty of generating single photons with specific wavelengths, bandwidths and brightness as well as the weak interaction probability of a single photon with an optical emitter pose a formidable challenge toward this goal. Here, we demonstrate a general approach based on the creation of single photons from a single emitter and their use for performing spectroscopy on a second emitter situated at a distance. Although we used organic molecules as emitters, our strategy is readily extendable to other material systems such as quantum dots and color centers. Our work ushers in a new line of experiments that provide access to the coherent and nonlinear couplings of few emitters and few propagating photons.

description: In proportion to the number of people, the number of techniques has also increased. However, each of the methods has both pros and cons. The operating principles of the old school are subject to sharp criticism today, despite the fact that the use of "classics" brought results, and considerable ones. The only question is at what cost were these results achieved? Typically, in order to master a language, I had to pore over books for a long time, devoting a lot of time to translating, reading texts, memorizing new words, performing various exercises and retelling. To change activities it was suggested tasks such as writing essays or dictations. One of the oldest techniques is classical or fundamental.

description: In this study, we considered stellar spots, stellar flares, and also the relation between these two magnetic proccesses that take place on UV Cet stars. In addition, the hypothesis about slow flares described by Gurzadyan (1986 Ap&SS, 125, 127) was investigated. All of these discussions were based on the results of three years of observations of UV Cet-type stars: AD Leo, EV Lac, V1005 Ori, EQ Peg, and V1054 Oph. First of all, the results show that stellar spot activity occurs on the stellar surface of EV Lac, V1005 Ori, and EQ Peg, while AD Leo does not show any short-term variability and V1054 Oph does not exhibit any variability. We report on new ephemerides for EV Lac, V1005 Ori, and EQ Peg, obtained from time-series analyses. The phases, computed at intervals of 0.10 phase length, where the mean flare occurence rates to obtain maximum amplitude; also, the phases of rotational modulation were compared in order to investigate whether there is any longitudinal relation between stellar flares and spots. Although the results show that flare events are related with spotted areas on stellar surfaces during some of the observing seasons, we did not find any clear correlation among them. Finally, it was tested whether slow flares are fast flares occurring on the opposite side of the stars according to the direction of the observers, as mentioned in a hypothesis developed by Gurzadyan (1986). The flare occurence rates reveal that both slow and fast flares can occur in any rotational phases. The flare occurence rates of both fast and slow flares vary in the same way along the longitudes for all program stars. These results are not expected based on the case mentioned in the hypothesis.

description: Solar photovoltaic tracking systems differ from fixed-tilt systems in that they track the position of the sun and in the process, partially shade one another over a range of solar angles. The resulting power loss calculations are non-linear and computationally intensive, so broad approximations are often applied in PV simulation tools. However, if one is to optimize the design of a solar PV tracking system, such as the arrangement and interconnection of PV cells and modules on a tracker, and the spacing between trackers and tracker rows, shading losses must be well understood and accurately accounted for. This thesis aims to design and implement a PV simulation model in MATLAB which predicts annual energy production using site-specific weather parameters while accurately accounting for shading losses at a PV-cell level. The model is then used to optimize the spacing of a hypothetical tracking system.
Women's decision making regarding hereditary breast and ovarian cancer risk-reducing strategies
Creators: name: Howard, Amanda Fuchsia Star
Publisher: name: University of British Columbia
Year: 2010

description: Women found to carry mutations in the BRCA1 or BRCA2 genes have up to an 88% lifetime risk of breast cancer and up to a 65% lifetime risk of ovarian cancer. Strategies to address these heightened risks include breast cancer screening, and risk-reducing (RR) surgeries (i.e., mastectomy and salpingo-oophorectomy). Some women might change their lifestyle or use complementary and alternative medicine to prevent hereditary breast and ovarian cancer (HBOC). The objectives of this research were to describe: a) the HBOC RR strategies used by women prior to receiving their genetic test results, the influence of individual and psychological factors on the uptake of these strategies, and their risk management information needs, b) how women construct the ‘right time’ to consider RR surgery decisions, and c) the process of making decisions regarding HBOC RR strategies. A survey of 143 women was conducted to address the first objective and in-depth interviews with 22 BRCA1/2 carriers were conducted to address the remaining two objectives. Survey respondents engaged in breast cancer screening at the time of genetic testing and a sub-group modified their lifestyle to reduce their cancer risk. Qualitative analyses revealed women’s constructions of the ‘right time’ to consider RR surgery decisions to be when: (1) decisions fit into their lives, (2) they had enough time to think about decisions, (3) they were ready emotionally, (4) all the issues and conflicts were sorted out, (5) there were better options available, and (6) the health care system was ready for them. Grounded theory analyses suggested that the overarching process of making decisions about HBOC RR strategies was one of ‘preserving the self.’ This process was shaped by the characteristics of health services, the nature of HBOC RR decisions, gendered roles, and the women’s perceived proximity to cancer. The women engaged in five decision-making styles, which were characterized by combinations of seven decision-making approaches. Findings from these three studies capture the diverse trajectories of decision making about HBOC risk management and highlight the role of personal and social context in shaping these decisions.

description: We present high signal-to-noise optical spectra for 67 low-redshift (0.1 < z < 0.4) galaxies that lie within close projected distances (5 kpc < rho < 150 kpc) of 38 background UV-bright QSOs. The Keck LRIS and Magellan MagE data presented here are part of a survey that aims to construct a statistically sampled map of the physical state and metallicity of gaseous galaxy halos using the Cosmic Origins Spectrograph (COS) on the Hubble Space Telescope (HST). We provide a detailed description of the optical data reduction and subsequent spectral analysis that allow us to derive the physical properties of this uniquely data-rich sample of galaxies. The galaxy sample is divided into 38 pre-selected L ~ L*, z ~ 0.2 "target" galaxies and 29 "bonus" galaxies that lie in close proximity to the QSO sightlines. We report galaxy spectroscopic redshifts accurate to +/- 30 km s-1, impact parameters, rest-frame colors, stellar masses, total star formation rates, and gas-phase interstellar medium oxygen abundances. When we compare the distribution of these galaxy characteristics to those of the general low-redshift population, we find good agreement. The L ~ L* galaxies in this sample span a diverse range of color (1.0 < u-r < 3.0), stellar mass (10^9.5 < M/M_sun < 10^11.5), and SFRs (0.01 - 20 M_sun yr-1). These optical data, along with the COS UV spectroscopy, comprise the backbone of our efforts to understand how halo gas properties may correlate with their host galaxy properties, and ultimately to uncover the processes that drive gas outflow and/or are influenced by gas inflow.

The purpose of this note is to give a characterization of this category (in a large class of categories), in terms of a 'Sierpinski-like' object, which is similar to the one given by E.G. Manes in 1976 for the category TOP of topological spaces.

description: In clinical studies, remaining symptomatic following the resolution of a major depressive episode has been identified as one of the strongest risk factors for relapse and recurrence, however this association has not been explored within a general population setting. Using the National Population Health Survey, individuals who were previously depressed but not currently were followed up prospectively over twelve years (n = 560). The K6 Distress Scale was used to evaluate residual symptomatology. Using proportional hazards and binomial regression modelling, residual symptoms (19.7%) were found to be associated with early recurrence; symptomatic individuals were over three times likely to experience a recurrence within four years (RR 3.2; 95% CI: 2.0-5.1; p < 0.001), with the presence of even a single symptom conferring a substantial increase in recurrence risk (RR 3.1; 95% CI: 1.7-5.5; p < 0.001).

description: Galaxy mass and environment are known to play a key role in galaxy evolution: looking at galaxy colors at different redshifts, fixed galaxy mass and environment, offers a powerful diagnosis to disentangle the role of each. In this work, we study the simulateneous dependence of the fraction of blue galaxies fblue on secular evolution, environment and galaxy mass with a well-controlled cluster sample. We are thus able to study the evolution and respective role of the cessation of star formation history (SFH) in clusters due to galaxy mass ("mass quenching") or to environment ("environmental quenching"). We define an homogenous X-ray selected cluster sample (25 clusters with 0 < z < 1 and one cluster at z \sim 2.2), having similar masses and well-defined sizes. Using multicolor photometry and a large spectroscopic sample to calibrate photometric redshifts, we carefully estimate fblue for each cluster at different galaxy mass and cluster-centric distance bins. We then fit with a simple model the dependence of fblue on redshift (z), environment (r/r200) and galaxy mass (M). fblue increases with cluster-centric distance with a slope $1.2^{+0.4}_{-0.3}$, decreases with galaxy mass with a slope $-3.8^{+0.6}_{-0.5}$, and increases with redshift with a slope $3.2^{+0.7}_{-0.5}$. The data also require for the first time a differential evolution with galaxy mass of fblue with redshift, with lower mass galaxies evolving slower by a factor $-4.1^{+1.1}_{-0.9}$. Our study shows that the processes responsible for the cessation of star formation in clusters are effective at all epochs (z<2.2), and more effective in denser environments and for more massive galaxies. We found that the mass and environmental quenchings are separable, that environmental quenching does not change with epoch, and that mass quenching is a dynamical process, i.e. its evolutionary rate is mass-dependent.

Terpenoid profiling and biosynthesis in Sitka spruce (Picea sitchensis) genotypes that are susceptible or resistant to attack by the white pine weevil (Pissodes strobi)
Creators: name: Robert, Jeanne A.

description: White pine weevil, Pissodes strobi, is an insect that occurs throughout Canada that attacks a number of conifers including Sitka spruce, Picea sitchensis, a commercially and ecologically important tree for coastal B.C.. Because of attack by weevils, Sitka spruce is no longer replanted as a commercial species. The re-introduction of this species would be a valuable asset for sustainable coastal forestry. My research addresses the terpene composition and the molecular-genetic underpinning of Sitka spruce resin defenses against attack by white pine weevil. In this thesis, I report that terpene profiles can be used to classify resistant tree genotypes. I analysed 111 different genotypes in order to determine the relationship of mono- and diterpenoid oleoresin compounds with the resistance rating. Dehydroabietic acid, a diterpene, was identified as a strong indicator of resistance. Two monoterpenes, (+)-3-carene and terpinolene were also associated with resistance in genotypes originating from the Haney region, an area which may have been subject to higher weevil pressure. In addition, I characterized weevil behavior and physiology (feeding patterns, host choice, ovary development, egg laying behavior, and larval development) in response to an extremely resistant Sitka spruce genotype (H898) in comparison to a highly susceptible genotype (Q903). My results suggest that the highly resistant genotype H898 has defense mechanisms that deter both male and female weevils during host selection and mating, that cause delayed ovary development in females, and prevent successful reproduction of weevils on H898 trees. Finally, I have identified the first (+)-3-carene and (+)-sabinene synthase genes in Sitka spruce. These terpene synthase (TPS) genes have very similar sequences, yet the encoded enzymes have different product profiles; this shows a new level of genetic diversity in the spruce TPS gene family. In addition, different (+)-3-carene synthase genes are expressed in the resistant H898 tree genotype producing large amounts of (+)-3-carene, versus the susceptible Q903 tree genotype that produces trace amounts of (+)-3-carene. This information will support the identification and breeding of resistant Sitka spruce in order to re-introduce it as a viable, native commercial species.

description: We propose a strong-coupling analysis of a polarizable planar interface, in the spirit of a recently introduced Wigner-Crystal formulation. The system is made up of two moieties: a semi-infinite medium (z<0) with permittivity epsilon' while the other half space in z>0 is occupied by a solution with permittivity epsilon, and mobile counter-ions (no added electrolyte). The interface at z=0 bears a uniform surface charge. The counter-ion density profile is worked out explicitly for both repulsive and attractive dielectric image cases.

description: This thesis presents the development of a creative, cross-curricular project series using the CDIO framework for engineering education to integrate engineering concepts and the Canadian Engineering Accreditation Board graduate attributes. The work in this thesis was targeted towards fifth grade students and their teachers, adapting the CDIO process to create an electrical engineering curriculum appropriate for elementary school, called Exploring Electrical Engineering. As studies show that students begin to lose interest in the domains of science, technology, mathematics and engineering during grades 4/5/6, this work also demonstrates how creative, hands-on projects and positive role models improve the perceptions that grade five students have towards engineering, and towards their consideration of engineering as a future career path. Through these contributions, the creative, cross-curricular CDIO-based Exploring Electrical Engineering program is demonstrated to have positive effects on young students while introducing them to engineering concepts and attributes.

description: Active control of the pump spatial profile is proposed to exercise control over random laser emission. We demonstrate numerically the selection of any desired lasing mode from the emission spectrum. An iterative optimization method is employed, first in the regime of strong scattering where modes are spatially localized and can be easily selected using local pumping. Remarkably, this method works efficiently even in the weakly scattering regime, where strong spatial overlap of the modes precludes spatial selectivity. A complex optimized pump profile is found, which selects the desired lasing mode at the expense of others, thus demonstrating the potential of pump shaping for robust and controllable singlemode operation of a random laser.

description: This work aims to search for the observational footprints of the interactions between the interstellar medium (ISM) and stellar winds in the Wolf-Rayet (WR) nebula NGC6888 in order to understand its ionization structure, chemical composition, and kinematics. We have collected a set of integral field spectroscopy observations across NGC6888, obtained with PPAK in the optical range performing both 2D and 1D analyses. Attending to the 2D analysis in the northeast part of NGC6888, we have generated maps of the extinction structure and electron density. We produced statistical frequency distributions of the radial velocity and diagnostic diagrams. We have found that the spectra of a localized region to the southwest of this pointing can be represented well by shock models. Furthermore, we performed a thorough study of integrated spectra in nine regions over the whole nebula. We derived electron densities ranging from <100 to 360 cm^(-3). The electron temperature varies from ~7700 K to ~10200 K. A strong variation of up to a factor 10 between different regions in the nitrogen abundance has been found: N/H appears lower than the solar abundance in those positions observed at the edges and very enhanced in the observed inner parts. Oxygen appears slightly underabundant with respect to solar value, whereas the helium abundance is found to be above it. Finally, we provide a scenario for the evolution of NGC6888 to explain the features observed. This scheme consists of a structure of multiple shells.

Mutuality and reciprocity in relationships: Generalist social workers’ considerations and strategies for managing their relationship with clients

subject: social worker-client relationship
subject: mutuality
subject: social work practice

description: Social work has struggled with the relational experience of mutuality and reciprocity since its early development as a profession (Addams, 1902; Reynolds, 1934; Biestek, 1957; Perlman, 1979; Kadushin, 1983). As social work professionalized it adopted objective and scientific approaches to work with clients and attempted to exclude expressions of mutuality and reciprocity from the relationship (Maidment, 2006). Social workers vary in their approach to this aspect of relational practice (Alexander, 2005). As the profession moves to re-examine the qualities and importance of relationship-based practice (Coady, 1993; Dybicz, 2012; Maidment, 2006; Morrison, 2007; Ruch, 2005, 2010), it is important to understand how mutuality and reciprocity are experienced in the field and how generalist social workers manage these elements of practice within the context of their work. The purpose of this study was to investigate how social workers negotiate variations in closeness and limits to mutuality and reciprocity in their relationships with clients. The methods are based on grounded theory methodology. Nineteen generalist social workers from a variety of fields of practice were asked about their methods of negotiating openness and limits to mutuality and reciprocity. Analyses of the interviews indicated that the social workers main concern was being uncomfortable. The core category of managing relationship emerged from the study. Managing relationship captures the actions, feelings, efforts, and range of possible success and struggles that the social workers experienced in their interactions with clients. The results of the study include the identification of six factors of these social workers’ relational practice: confidence; authentic self; professional maturity; self-regulation; practice skill and knowledge; and systemic perspective. The six factors are a part of the process of managing relationships, and are explained and illustrated by participants’ examples.

description: We experimentally studied the spatial coherence of random laser emission from dye solutions containing nanoparticles. The spatial coherence, measured in a double-slit experiment, varied significantly with the density of scatterers and the size and shape of the excitation volume. A qualitative explanation is provided, illustrating the dramatic difference from the spatial coherence of a conventional laser. This work demonstrates that random lasers can be controlled to provide intense, spatially incoherent emission for applications in which spatial cross talk or speckle limit performance.

DEVELOPING CRITICAL THINKING THROUGH READING ACTIVITIES IN HIGHER EDUCATION SYSTEM
Creators: name: Turdieva, Roza
Publisher: name: Zenodo
Year: 2023

description: In order to activate students' critical thinking skills, English teachers need to present alternatives, different ways of interpreting texts and different conceptions of the world. The importance of thinking in today's education requires the main concept of critical thinking in which there is always more than one way to see things and that it is always up to the individual to judge just where the truth lies on any given issue. Regarding the flexible nature of critical thinking, the writer proposes a teaching practice that can be modified in different ways.

description: Pregnancy and childbirth are important milestones in the development of a family. Birth plans allow childbearing women to plan and express their wishes for their birth experience. Labour and delivery nurses play a key role in providing care on birthing units in Canada and are uniquely placed to enact a woman’s birth plan. A focused ethnographic study was undertaken to examine birthing unit culture and its impact on how labour and delivery nurses care for women with birth plans. Findings revealed three overarching themes (ensuring safe care, teamwork, and connecting with patients) that shaped birthing unit culture and impacted how labour and delivery nurses viewed and enacted birth plans. Organizational influences and individual healthcare provider preferences influenced how birth plans were enacted on the unit. Patient safety was a dominant driver of care. Challenges exist on how to partner with childbearing women and their families while assisting them in the goals for their birth experience. Collaboration is key as providers strive to embrace a woman’s birth plan expectations and work toward a shared understanding and partnership in childbirth.

description: We obtain several rigidity results for biharmonic submanifolds in $\mathbb{S}^{n}$ with parallel normalized mean curvature vector field. We classify biharmonic submanifolds in $\mathbb{S}^{n}$ with parallel normalized mean curvature vector field and with at most two distinct principal curvatures. In particular, we determine all biharmonic surfaces with parallel normalized mean curvature vector field in $\mathbb{S}^n$. Then we investigate, for (not necessarily compact) proper biharmonic submanifolds in $\mathbb{S}^n$, their type in the sense of B-Y. Chen. We prove: (i) a proper biharmonic submanifold in $\mathbb{S}^n$ is of 1-type or 2-type if and only if it has constant mean curvature ${\mcf}=1$ or ${\mcf}\in(0,1)$, respectively; (ii) there are no proper biharmonic 3-type submanifolds with parallel normalized mean curvature vector field in $\mathbb{S}^n$.

description: Total knee arthroplasty is a surgical procedure in which the knee is resurfaced with implants to relieve pain. This thesis presents computed tomography and radiography methods to determine the relative position (kinematics) for the patellofemoral and tibiofemoral joints in vivo for a full range of motion, as well as parameters related to surgical technique. These methods were used to compare: (1) subjects with gender-specific (GS) versus traditional implant designs, (2) symptomatic versus asymptomatic subjects, and (3) static versus dynamic kinematics. Quality of life (QOL) was also measured. GS implants only had a small but significant difference in patellofemoral translation in early flexion; no other differences were found for the kinematics or QOL. For all symptomatic subjects, differences in kinematics or surgical parameters were found, suggesting the cause for the subject’s postoperative pain. Static and dynamic kinematics were comparable in all but one case, where internal/external tibial rotation differed.
