description: A monopolist is treated as a nexus of contracts with team production. It has one ownermanager. The owner-manager is the employer of two employees. A team production problem is present if the employer is a “managerial lemon”. If the team production problem is solved, the employer is a “managerial hotshot”. Both a managerial hotshot and a managerial lemon are found to make profit. Managerial slack can therefore exist in our monopoly market. In the case of a managerial lemon, the profit level is lower. However, the employees’ utility level is higher. Whereas the employer has an incentive to improve management capability in principle, the employees have an incentive to keep management capability low. Moreover, the cost of improving management capability may be prohibitively high. Managerial slack can therefore persist. The predicted behavior of the monopolist is grounded in individual behavior under the assumption of utility maximization.

description: We consider interacting Fermi systems close to the unitary regime and compute the corrections to the energy density that are due to a large scattering length and a small effective range. Our approach exploits the universality of the density functional and determines the corrections from the analyical results for the harmonically trapped two-body system. The corrections due to the finite scattering length compare well with the result of Monte Carlo simulations. We also apply our results to symmetric neutron matter.

Central bankers
nearest neighbor matching.

description: The personalities of central bankers moved center stage during the recent
financial crisis. Some central bankers even gained \superstar" status. In this
paper, we evaluate the pivotal role of superstar central bankers by assessing
the difference an outstanding governor makes to economic performance. We
employ school grades given to central bankers by the financial press. A superstar central banker is one receiving the top grade. In a probit estimation
we first relate the grades to measures of economic performance, institutional
features, and personal characteristics. We then employ a nearest neighbor
matching approach to identify the central bankers which are closest to those
receiving the top grade and compare the economic performance across both
groups. The results suggest that a superstar governor indeed matters: a topgraded central banker faces a significantly more favorable output-in
ation trade-off than his peers. This effect is driven by outstanding central bankers in emerging markets.

description: Background The Planetary Health Diet Index (PHDI) measures adherence to the dietary pattern presented by the EAT-Lancet Commission, which aligns health and sustainability targets. There is a need to understand how PHDI scores correlate with dietary greenhouse gas emissions (GHGE) and how this differs from the carbon footprints of scores on established dietary recommendations. The objectives of this study were to compare how the PHDI, Healthy Eating Index-2015 (HEI-2015) and Dietary Approaches to Stop Hypertension (DASH) relate to (a) dietary GHGE and (b) to examine the influence of PHDI food components on dietary GHGE. Methods We used life cycle assessment data from the Database of Food Recall Impacts on the Environment for Nutrition and Dietary Studies to calculate the mean dietary GHGE of 8,128 adult participants in the 2015–2016 and 2017–2018 cycles of the National Health and Nutrition Examination Survey (NHANES). Poisson regression was used to estimate the association of (a) quintiles of diet score and (b) standardized dietary index Z-scores with dietary GHGE for PHDI, HEI-2015, and DASH scores. In secondary analyses, we used Poisson regression to assess the influence of individual PHDI component scores on dietary GHGE. Results We found that higher dietary quality on all three indices was correlated with lower dietary GHGE. The magnitude of the dietary quality-dietary GHGE relationship was larger for PHDI [-0.4, 95% CI (-0.5, -0.3) kg CO2 equivalents per one standard deviation change] and for DASH [-0.5, (-0.4, -0.6) kg CO2-equivalents] than for HEI-2015 [-0.2, (-0.2, -0.3) kg CO2-equivalents]. When examining PHDI component scores, we found that diet-related GHGE were driven largely by red and processed meat intake. Conclusions Improved dietary quality has the potential to lower the emissions impacts of US diets. Future efforts to promote healthy, sustainable diets could apply the recommendations of the established DASH guidelines as well as the new guidance provided by the PHDI to increase their environmental benefits.

description: The magma ocean concept was first conceived to explain the geology of the Moon, but hemispherical or global oceans of silicate melt could be a widespread "lava world" phase of rocky planet accretion, and could persist on planets on short-period orbits around other stars. The formation and crystallization of magma oceans could be a defining stage in the assembly of a core, origin of a crust, initiation of tectonics, and formation of an atmosphere. The last decade has seen significant advances in our understanding of this phenomenon through analysis of terrestrial and extraterrestrial samples, planetary missions, and astronomical observations of exoplanets. This review describes the energetic basis of magma oceans and lava worlds and the lava lake analogs available for study on Earth and Io. It provides an overview of evidence for magma oceans throughout the Solar System and considers the factors that control the rocks these magma oceans leave behind. It describes research on theoretical and observed exoplanets that could host extant magma oceans and summarizes efforts to detect and characterize them. It reviews modeling of the evolution of magma oceans as a result of crystallization and evaporation, the interaction with the underlying solid mantle, and the effects of planetary rotation. The review also considers theoretical investigations on the formation of an atmosphere in concert with the magma ocean and in response to irradiation from the host star, and possible end-states. Finally, it describes needs and gaps in our knowledge and points to future opportunities with new planetary missions and space telescopes to identify and better characterize lava worlds around nearby stars.

description: Horizontal gene transfer is a source of metabolic innovation and adaptation to new environments. How new metabolic functionalities are integrated into host cell biology is largely unknown. Here, we probe this fundamental question using the fission yeast Schizosaccharomyces japonicus, which has acquired a squalene-hopene cyclase Shc1 through horizontal gene transfer. We show that Shc1-dependent production of hopanoids, mimics of eukaryotic sterols, allows S. japonicus to thrive in anoxia, where sterol biosynthesis is not possible. We demonstrate that glycerophospholipid fatty acyl asymmetry, prevalent in S. japonicus, is crucial for accommodating both sterols and hopanoids in membranes and explain how Shc1 functions alongside the sterol biosynthetic pathway to support membrane properties. Reengineering experiments in the sister species S. pombe show that hopanoids entail new traits in a naïve organism, but the acquisition of a new enzyme may trigger profound reorganization of the host metabolism and physiology.

description: We analyze {\em the Rosenblatt process} which is a selfsimilar process with stationary increments and which appears as limit in the so-called {\em Non Central Limit Theorem} (Dobrushin and Major (1979), Taqqu (1979)). This process is non-Gaussian and it lives in the second Wiener chaos. We give its representation as a Wiener-Itô multiple integral with respect to the Brownian motion on a finite interval and we develop a stochastic calculus with respect to it by using both pathwise type calculus and Malliavin calculus.

description: The experiments involving a slider moving on top of granular media consisting of photoelastic particles in two dimensions have uncovered elaborate dynamics that may vary from continuous motion to crackling, periodic motion, and stick-slip type of behavior. We establish that there is a clear correlation between the slider dynamics and the response of the force network that spontaneously develop in the granular system. This correlation is established by application of the persistence homology that allows for formulation of objective measures for quantification of time-dependent force networks. We find that correlation between the slider dynamics and the force network properties is particularly strong in the dynamical regime characterized by well-defined stick-slip type of dynamics.

description: Purpose Survivin/BIRC5 is a proliferation marker that is associated with poor prognosis in breast cancer and an attractive therapeutic target. However, BIRC5 has not been well studied among racially diverse populations where aggressive breast cancers are prevalent. Experimental design We studied BIRC5 expression in association with clinical and demographic variables and as a predictor of recurrence in 2174 participants in the Carolina Breast Cancer Study (CBCS), a population-based study that oversampled Black (n = 1113) and younger (< 50 years; n = 1137) participants with breast cancer. For comparison, similar analyses were conducted in The Cancer Genome Atlas [TCGA N = 1094, Black (n = 183), younger (n = 295)]. BIRC5 was evaluated as a continuous and categorical variable (highest quartile vs. lower three quartiles). Results Univariate, continuous BIRC5 expression was higher in breast tumors from Black women relative to non-Black women in both estrogen receptor (ER)-positive and ER-negative tumors and in analyses stratified by stage (i.e., within Stage I, Stage II, and Stage III/IV tumors). Within CBCS and TCGA, BIRC5-high was associated with young age (< 50 years) and Black race, as well as hormone receptor-negative tumors, non-Luminal A PAM50 subtypes, advanced stage, and larger tumors (> 2 cm). Relative to BIRC5-low, BIRC5-high tumors were associated with poor 5-year recurrence-free survival (RFS) among ER-positive tumors, both in unadjusted models [HR (95% CI): 2.7 (1.6, 4.6)] and after adjustment for age and stage [Adjusted HR (95% CI): 1.87 (1.07, 3.25)]. However, this relationship was not observed among ER-negative tumors [Crude HR (95% CI): 0.7 (0.39, 1.2); Adjusted HR (95% CI): 0.67 (0.37, 1.2)]. Conclusion Black and younger women with breast cancer have a higher burden of BIRC5-high tumors than older and non-Black women. Emerging anti-survivin treatment strategies may be an important future direction for equitable breast cancer outcomes.

description: BACKGROUND: Frailty is a dynamic syndrome characterized by reduced physiological reserve to maintain homeostasis. Prospective studies have reported frailty worsening in women with breast cancer during chemotherapy, with improvements following treatment. We evaluated whether the Faurot frailty index, a validated claims-based frailty measure, could identify changes in frailty during chemotherapy treatment and identified predictors of trajectory patterns.
METHODS: We included women (65+ years) with stage I-III breast cancer undergoing adjuvant chemotherapy in the SEER-Medicare database (2003-2019). We estimated the Faurot frailty index (range: 0-1; higher scores indicate greater frailty) at chemotherapy initiation, 4 months postinitiation, and 10 months postinitiation. Changes in frailty were compared to a matched noncancer comparator cohort. We identified patterns of frailty trajectories during the year following chemotherapy initiation using K-means clustering.
RESULTS: Twenty-one thousand five hundred and ninety-nine women initiated adjuvant chemotherapy. Mean claims-based frailty increased from 0.037 at initiation to 0.055 4 months postchemotherapy initiation and fell to 0.049 10 months postinitiation. Noncancer comparators experienced a small increase in claims-based frailty over time (0.055-0.062). We identified 6 trajectory patterns: a robust group (78%), 2 resilient groups (16%), and 3 nonresilient groups (6%). Black women and women with claims for home hospital beds, wheelchairs, and Parkinson's disease were more likely to experience nonresilient trajectories.
CONCLUSIONS: We observed changes in a claims-based frailty index during chemotherapy that are consistent with prior studies using clinical measures of frailty and identified predictors of nonresilient frailty trajectories. Our study demonstrates the feasibility of using claims-based frailty indices to assess changes in frailty during cancer treatment.

description: BACKGROUND: Breast cancer survivors (BCSs) report persistent, diminished ability to work, and decreased health-related quality of life (HRQoL). Cancer rehabilitation interventions (physical therapy or occupational therapy [PT/OT]) aim to improve these outcomes, but little is known about their impact in the community.
METHODS: This retrospective, pre-post, uncontrolled study examined cases of younger BCSs (age <65 years) who attended cancer-specialized PT/OT over a 2-year period. Outcomes and covariates (age, race, US region, payer type, number of visits, length of care [weeks]) were extracted from electronic medical records. Patient-reported outcomes were overall-Work Ability Score (WASoverall), physical-WAS (WASphysical), and mental-WAS (WASmental) and PROMIS Global Physical Health (GPH), Global Mental Health (GMH), Physical Function (PF), and Ability to Participate in Social Roles and Activities (SRA). We used linear mixed effect models to examine pre- to post-rehabilitation change overall, and separately, while controlling for covariates.
RESULTS: PT/OT cases (NPT=758; NOT=140) had a mean [SD] age of 51.39 [8.49] years and attended approximately 12 visits (IQR, 8.0-19.0) over 10.71 weeks (IQR, 6.14-17.00). Overall, work ability outcomes (WASoverall: +1.79; WASphysical: +0.78; WASmental: +0.47; all P<.001) and HRQoL outcomes improved significantly (GPH: +5.38; GMH: +2.90; PF: +5.17; SRA: +5.83; all P<.001), and average change on each HRQoL outcome exceeded the minimal important change (2 points). Outcome scores were similar at each timepoint for both PT and OT cases (all P>.05) and both groups improved significantly (all P<.01).
CONCLUSIONS: In this large study of the impact of cancer-specialized, community-based PT and OT, younger BCSs reported significant improvement in ability to work and HRQoL. Although more research is needed, these findings suggest improved access to PT/OT could improve work ability and HRQoL for younger BCSs.

description: Convolutional neural networks (CNNs), inspired by biological visual cortex systems, are a powerful category of artificial neural networks that can extract the hierarchical features of raw data to greatly reduce the network parametric complexity and enhance the predicting accuracy. They are of significant interest for machine learning tasks such as computer vision, speech recognition, playing board games and medical diagnosis. Optical neural networks offer the promise of dramatically accelerating computing speed to overcome the inherent bandwidth bottleneck of electronics. Here, we demonstrate a universal optical vector convolutional accelerator operating beyond 10 TeraFLOPS (floating point operations per second), generating convolutions of images of 250,000 pixels with 8 bit resolution for 10 kernels simultaneously, enough for facial image recognition. We then use the same hardware to sequentially form a deep optical CNN with ten output neurons, achieving successful recognition of full 10 digits with 900 pixel handwritten digit images with 88% accuracy. Our results are based on simultaneously interleaving temporal, wavelength and spatial dimensions enabled by an integrated microcomb source. This approach is scalable and trainable to much more complex networks for demanding applications such as unmanned vehicle and real-time video recognition.

description: Background Patients with inflammatory breast cancer (IBC) have overall poor clinical outcomes, with triple-negative IBC (TN-IBC) being associated with the worst survival, warranting the investigation of novel therapies. Preclinical studies implied that ruxolitinib (RUX), a JAK1/2 inhibitor, may be an effective therapy for TN-IBC. Methods We conducted a randomized phase II study with nested window-of-opportunity in TN-IBC. Treatment-naïve patients received a 7-day run-in of RUX alone or RUX plus paclitaxel (PAC). After the run-in, those who received RUX alone proceeded to neoadjuvant therapy with either RUX + PAC or PAC alone for 12 weeks; those who had received RUX + PAC continued treatment for 12 weeks. All patients subsequently received 4 cycles of doxorubicin plus cyclophosphamide prior to surgery. Research tumor biopsies were performed at baseline (pre-run-in) and after run-in therapy. Tumors were evaluated for phosphorylated STAT3 (pSTAT3) by immunostaining, and a subset was also analyzed by RNA-seq. The primary endpoint was the percent of pSTAT3-positive pre-run-in tumors that became pSTAT3-negative. Secondary endpoints included pathologic complete response (pCR). Results Overall, 23 patients were enrolled, of whom 21 completed preoperative therapy. Two patients achieved pCR (8.7%). pSTAT3 and IL-6/JAK/STAT3 signaling decreased in post-run-in biopsies of RUX-treated samples, while sustained treatment with RUX + PAC upregulated IL-6/JAK/STAT3 signaling compared to RUX alone. Both treatments decreased GZMB+ T cells implying immune suppression. RUX alone effectively inhibited JAK/STAT3 signaling but its combination with PAC led to incomplete inhibition. The immune suppressive effects of RUX alone and in combination may negate its growth inhibitory effects on cancer cells. Conclusion In summary, the use of RUX in TN-IBC was associated with a decrease in pSTAT3 levels despite lack of clinical benefit. Cancer cell-specific-targeting of JAK2/STAT3 or combinations with immunotherapy may be required for further evaluation of JAK2/STAT3 signaling as a cancer therapeutic target.Trial registrationwww.clinicaltrials.gov, NCT02876302.

description: Matching articulated shapes represented by voxel-sets reduces to maximal sub-graph isomorphism when each set is described by a weighted graph. Spectral graph theory can be used to map these graphs onto lower dimensional spaces and match shapes by aligning their embeddings in virtue of their invariance to change of pose. Classical graph isomorphism schemes relying on the ordering of the eigenvalues to align the eigenspaces fail when handling large data-sets or noisy data. We derive a new formulation that finds the best alignment between two congruent $K$-dimensional sets of points by selecting the best subset of eigenfunctions of the Laplacian matrix. The selection is done by matching eigenfunction signatures built with histograms, and the retained set provides a smart initialization for the alignment problem with a considerable impact on the overall performance. Dense shape matching casted into graph matching reduces then, to point registration of embeddings under orthogonal transformations; the registration is solved using the framework of unsupervised clustering and the EM algorithm. Maximal subset matching of non identical shapes is handled by defining an appropriate outlier class. Experimental results on challenging examples show how the algorithm naturally treats changes of topology, shape variations and different sampling densities.

description: Abstract

Background of the Study: Stress is the feeling of being under too much mental or emotional pressure. Pressure turns into stress when you feel unable to cope. People have different ways of reacting to stress, so a situation that feels stressful to one person may in fact be motivating to another. Many of life's demands can cause stress, especially work, relationships and money problems, and when you feel stressed, it can affect everything you do. Stress can affect how you feel, how you think, how you behave and how your body works. Sleeping problems, sweating, loss of appetite and difficulty concentrating are common signs of stress. Transition from secondary school to higher education is usually hard and demanding experience for students which lead to stress. Objectives: A study to assess the level of stress among nursing students. Materials and Methods: A descriptive design was chosen for the study to assess the level of stress among nursing students. A total of 60 nursing students were selected by simple random sampling technique using Lottery method was used, 60 B.sc nursing I year students were selected for the data collection procedure. The data collection was conducted among the 60 nursing students by using Perceived Stress scale. Level of stress was identified as mild, moderate, severe and very severe level of stress. The collected data were analyzed using descriptive and inferential statistics. Results: In general, none of the nursing students are having mild-stress score. In 60 samples, level of stress among the nursing students’ moderate level of stress were 24[40%], perceived severe level of stress among the nursing students were 35[58.3%]. Perceived very severe level of stress among the nursing students was 1[1.66%]. In this study, the highest score was severe level of stress was scored among nursing students. The level of stress had significant association chi-square value with demographic variables of Domicile [Urban and Rural], significant association level of stress among B.Sc. Nursing students with chi- square value of x2=8.9, df=3 at p > 0.05 level. Conclusion: Assessing stress among Nursing students in colleges is important for the students’ wellbeing and academic performance.
PCN: a deep learning approach to jet tagging utilizing novel graph construction methods and Chebyshev graph convolutions

description: Jet tagging is a classification problem in high-energy physics experiments that aims to identify the collimated sprays of subatomic particles, jets, from particle collisions and ‘tag’ them to their emitter particle. Advances in jet tagging present opportunities for searches of new physics beyond the Standard Model. Current approaches use deep learning to uncover hidden patterns in complex collision data. However, the representation of jets as inputs to a deep learning model have been varied, and often, informative features are withheld from models. In this study, we propose a graph-based representation of a jet that encodes the most information possible. To learn best from this representation, we design Particle Chebyshev Network (PCN), a graph neural network (GNN) using Chebyshev graph convolutions (ChebConv). ChebConv has been demonstrated as an effective alternative to classical graph convolutions in GNNs and has yet to be explored in jet tagging. PCN achieves a substantial improvement in accuracy over existing taggers and opens the door to future studies into graph-based representations of jets and ChebConv layers in high-energy physics experiments.

description: Particle acceleration at astrophysical shocks may be very efficient if magnetic scattering is self-generated by the same particles. This nonlinear process adds to the nonlinear modification of the shock due to the dynamical reaction of the accelerated particles on the shock. Building on a previous general solution of the problem of particle acceleration with arbitrary diffusion coefficients (Amato & Blasi, 2005), we present here the first semi-analytical calculation of particle acceleration with both effects taken into account at the same time: charged particles are accelerated in the background of Alfven waves that they generate due to the streaming instability, and modify the dynamics of the plasma in the shock vicinity.

The significance accorded to the infant mortality rate reflected both contemporary Western notions about the health of the nation and good government, and long-standing associations of Chinese culture with infanticide. Initial investigations focused on deaths from tetanus neonatorum in local Western charitable institutions. Further reports in the mid-1890s blamed Chinese midwives for infant deaths, and some officials pressed for the regulation of these women. The course of the ensuing debate, which spanned a decade and a half, illustrated the politics of public health in the colony, whereby the Hong Kong government consulted with members of the Chinese elite and sought compromise, so as not to antagonise the Chinese population. The resulting Midwives Ordinance of 1910 thus did not affect Chinese midwives unless they claimed to have Western training. Rather than attempt to proscribe the native midwives, the government supported local training initiatives in the hope that Western-style birth professionals would gradually prevail.

description: We present an in-depth study of the universal correlations of scattering-matrix entries required in the framework of non-stationary many-body scattering where the incoming states are localized wavepackets. Contrary to the stationary case the emergence of universal signatures of chaotic dynamics in dynamical observables manifests itself in the emergence of universal correlations of the scattering matrix at different energies. We use a semiclassical theory based on interfering paths, numerical wave function based simulations and numerical averaging over random-matrix ensembles to calculate such correlations and compare with experimental measurements in microwave graphs, finding excellent agreement. Our calculations show that the universality of the correlators survives the extreme limit of few open channels relevant for electron quantum optics, albeit at the price of dealing with large-cancellation effects requiring the computation of a large class of semiclassical diagrams.

description: A quantum master equation (QME) is derived for the many-body density matrix of an open current-carrying system weakly coupled to two metal leads. The dynamics and the steady-state properties of the system for arbitrary bias are studied using projection operator techniques, which keep track of number of electrons in the system. We show that coherences between system states with different number of electrons, n, (Fock space coherences) do not contribute to the transport to second order in system-lead coupling. However, coherences between states with the same n may effect transport properties when the damping rate is of the order or faster then the system Bohr frequencies. For large bias, when all the system many-body states lie between the chemical potentials of the two leads, we recover previous results. In the rotating wave approximation (when the damping is slow compared to the Bohr frequencies of the system), the dynamics of populations and the coherences in the system eigenbasis are decoupled. The QME then reduces to a birth and death master equation for populations.

description: We demonstrate that virtual excitations of higher radial modes in an atomic Bose gas in a tightly confining waveguide result in effective three-body collisions that violate integrability in this quasi-one-dimensional quantum system and give rise to thermalization. The estimated thermalization rates are consistent with recent experimental results in quasi-1D dynamics of ultracold atoms.

description: Pre-proof versionABSTRACT: In this work, we studied the effect of inorganic ions occurring in natural waters on E. coli inactivation by solar and photo-Fenton processes, two crucial methods for drinking water treatment in sunny or developing countries. HCO3-,Cl-,SO42-,NO3-, NO2- and NH4+ were assessed at relevant concentrations for their inhibiting or facilitating role. The inactivation enhancement during solar disinfection (SODIS) was mainly attributed to the generation of HO• radicals produced during by excitation of NO3-, NO2-, while the HO• of photo-Fenton may be transformed into other radical species in presence of ions. Natural organic matter (NOM) was found to enhance both processes but also to hinder most of the enhancing ions, except for NO2-; modeling with the APEX software unveiled the inter-relations in the presence of NOM, and the possible inactivation activity by NO2•. The photo-Fenton inactivation was more significantly enhanced by ions than SODIS (besides the case of NO3-, NO2-), but both processes were found robust enough.

description: Presenting long sequences of dynamic graphs remains challenging due to the underlying large-scale and high-dimensional data. We propose dg2pix, a novel pixel-based visualization technique, to visually explore temporal and structural properties in long sequences of large-scale graphs. The approach consists of three main steps: (1) the multiscale modeling of the temporal dimension; (2) unsupervised graph embeddings to learn low-dimensional representations of the dynamic graph data; and (3) an interactive pixel-based visualization to simultaneously explore the evolving data at different temporal aggregation scales. dg2pix provides a scalable overview of a dynamic graph, supports the exploration of long sequences of high-dimensional graph data, and enables the identification and comparison of similar temporal states. We show the applicability of the technique to synthetic and real-world datasets, demonstrating that temporal patterns in dynamic graphs can be identified and interpreted over time. dg2pix contributes a suitable intermediate representation between node-link diagrams at the high detail end and matrix representations on the low detail end.

description: We develop a model for ferromagnetic resonance in systems with competing uniaxial and cubic anisotropies. This model applies to (i) magnetic materials with both uniaxial and cubic anisotropies, and (ii) magnetic nanoparticles with effective core and surface anisotropies; We numerically compute the resonance frequency as a function of the field and the resonance field as a function of the direction of the applied field for an arbitrary ratio of cubic-to-uniaxial anisotropy. We also provide some approximate analytical expressions in the case of weak cubic anisotropy. We propose a method that uses these expressions for estimating the uniaxial and cubic anisotropy constants, and for determining the relative orientation of the cubic anisotropy axes with respect to the crystal principle axes. This method is applicable to the analysis of experimental data of resonance type measurements for which we give a worked example of an iron thin film with mixed anisotropy.

description: Survey data from the Mayo Clinic Breast Disease Registry were used to assess fertility counseling and fertility preservation strategies in a modern cohort of young women with breast cancer. One hundred respondents were identified who were under age 50 at the time of breast cancer diagnosis and who expressed interest in future childbearing near the time of diagnosis and/or 1 year later. Ninety-three percent of the 81 respondents to the year one survey recalled fertility counseling prior to cancer treatment. Most who reported a high level of fertility concern declared that this concern had impacted their treatment decisions, often shortening their planned duration of endocrine therapy. Approximately half had taken steps to preserve future fertility, and a third had used a gonadotropin-releasing hormone agonist either alone or combined with another method (e.g., embryo or oocyte cryopreservation).
Beyond command and control : do voluntary initiatives hold promise for enhanced environmental protection?
Creators: name: Parker, David Richard
Publisher: name: University of British Columbia

description: This thesis studies current trends in environmental regulation that represent a shift away from "command and control" and "end of pipe" regulation to voluntary, cooperative approaches that are focused on pollution prevention. The focus is on the regulation of big industry and in particular mining and metals production. Although experiences in other jurisdictions are considered, the primary focus of this thesis is on British Columbia and Canada. Chapter One sets out the methodology employed in preparing the thesis. Chapter Two examines problems associated with traditional approaches to command and control and end of pipe regulation. Shortcomings in existing regulation are identified. Chapter Three identifies many of the expectations and goals of stakeholders with an interest in environmental protection and sustainable development. Reference is made to the interests of government, environmental non-governmental organizations, and, in particular, the private sector/business community. Chapter Four considers four current initiatives which are representative of a trend toward cooperative, voluntary approaches. Chapter Five addresses two questions: (1) what factors and considerations inherent in the reviewed initiatives increase their chances for success? and; (2) what conditions and parameters need to be present to satisfy society's expectations and optimize environmental protection? In addressing these questions, the author sets out several factors that may be important in achieving successful outcomes from voluntary initiatives. Chapter Six concludes that, if the factors outlined in the thesis are employed, society will move closer to achieving an operable state of interdependence, which is essential if optimal environmental protection is to be realized. However, such a result will depend upon the degree of commitment of stakeholders, and in particular, the private sector.

description: For the double complex structure of grading-restricted vertex algebra cohomology defined in \cite{Huang}, we introduce a multiplication of elements of double complex spaces. We show that the orthogonality and bi-grading conditions applied on double complex spaces, provide in relation among mappings and actions of co-boundary operators. Thus, we endow the double complex spaces with structure of bi-graded differential algebra. We then introduce the simples cohomology classes for a grading-restricted vertex algebra, and show their independence on the choice of mappings from double complex spaces. We prove that its cohomology class does not depend on mappings representing of the double complex spaces. Finally, we show that the orthogonality relations together with the bi-grading condition bring about generators and commutation relations for a continual Lie algebra.
