“Things change, things aren’t always a given”: Exploring the Experiences of Miscarriage: A Narrative Analysis.

description: Introduction: Miscarriage continues to be a prevalent experience; one in four pregnancies will end in miscarriage and is the most common adverse outcome of pregnancy. It can be both emotionally and physically impactful, yet often goes unrecognised and rarely discussed. Literature reviewed highlighted the societal and medical discourses that surround pregnancy and motherhood, yet how such socio-political discourses influence a miscarriage experience have been seldomly explored. This alongside a lack of discussion on embodied experiences prompted an exploration of the ways individuals narrate and share their stories of miscarriage. Methods: Eight women who had experiences of miscarriage were interviewed to collect data that related to the ways participants constructed narratives and how these influenced their sense-of-self. An interest in embodiment theory and socio-political discourse developed from the literature review, led to the application of visual methods as part of interviews, to help generate narratives. A critical narrative analysis was then utilised to explore the data collected. Findings: Participants drew from ‘medical’, ‘natural instinct’ and ‘social expectation’ discourses, which generated narratives of failure, self-blame and guilt. Discourses which adhere to linear notions of progress, led participants to feel disempowered with limited agency over their bodies and subjective experience. In the absence of societal norms and public discussion around miscarriage, participants often felt unaware and unprepared and attempted to make sense of their experience in isolation using a range of frameworks and perspectives. Discussion: Findings emphasise the ways in which individuals felt disempowered with limited self-agency, and viewed their subjective experiences as neglected. Due to the lack of available discourse and prevailing assumptions which link pregnancy and motherhood to female identity, miscarriage remains a stigmatised and marginalised experience. Implications of the findings are to support a social justice agenda in clinical practice, in order to reduce the silence and taboo associated with miscarriage. Furthermore, it is highlighted that working with the body in therapy may counter a mind/body dualism, which can facilitate raising awareness of subjective experience.

description: Los derechos de propiedad intelectual son uno de los mayores retos que afronta la sociedad del siglo XXI. Los cambios impulsados por las nuevas tecnologías, y más concretamente Internet, en aspectos como la estructura del trabajo, la gestión de la información y los modelos de producción, han provocado una manifiesta obsolescencia de las legislaciones a la hora de regular los nuevos sistemas de la información. En este trabajo se analiza como, desde la perspectiva de la propiedad intelectual, el legislador debe contemplar los cambios relativos a la sociedad del conocimiento; si bien se sugiere que éste debería no olvidar su perspectiva ante las presiones a las que se le somete por las sociedades empresariales de gestión de derechos. Observaremos, desde una fundamentación histórica, como toda revolución suele conllevar una alteración de la normativa de la propiedad intelectual, si bien ha surgido un conflicto entre los derechos fundamentales de los ciudadanos ―al secreto de las comunicaciones― y los intereses de los autores y editores. Estos últimos simplemente pretenden el control de "la Red", siguiendo una antigua tradición.

description: This paper focuses on improved storage and preservation technologies as an adaptation strategy in response to climate change. We also study the trade-off between improved cereal storage technologies and the preservation techniques among rural households in Tanzania. We find that climate variables significantly influence farmers’ choice of improved storage technologies and preserving decisions. Using a bivariate probit model, we find that modern storage technologies and preservation measures are substitutes. Farmers can significantly reduce annual costs associated with preservation by adopting (usually long lasting) modern storage facilities.

description: A theoretical treatment of the static structure factor $S(k)$ of a Bose gas is attempted. The low order expansion theory is implemented for the construction of the two body density distribution, while various trial functions for the radial distribution function $g(r)$ are used. $g(r)$ introduces the atomic correlations and describes the departure from the noninteracting gas. The Bose gas is studied as inhomogeneous one, trapped in harmonic oscillator well, as well as homogeneous. A suitable parametrization of the various trial functions $g(r)$ exists which leads to satisfactory reproduction of the experimental values of $S(k)$, both in inhomogeneous case as well as in homogeneous one. The phonon range behavior of the calculated $S(k)$ is also addressed and discussed both in finite and infinite Bose gas.

description: Understanding the evolution and cosmological consequences of topological defect networks requires a combination of analytic modeling and numerical simulations. The canonical analytic model for defect network evolution is the Velocity-dependent One-Scale (VOS) model. For the case of cosmic strings, this has so far been calibrated using small numbers of Goto-Nambu and field theory simulations, in the radiation and matter eras, as well as in Minkowski spacetime. But the model is only as good as the available simulations, and it should be extended as further simulations become available. In previous work we presented a General Purpose Graphics Processing Unit implementation of the evolution of cosmological domain wall networks, and used it to obtain an improved VOS model for domain walls. Here we continue this effort, exploiting a more recent analogous code for local Abelian-Higgs string networks. The significant gains in speed afforded by this code enabled us to carry out 1032 field theory simulations of $512^3$ size, with 43 different expansion rates. This detailed exploration of the effects of the expansion rate on the network properties in turn enables a statistical separation of various dynamical processes affecting the evolution of the network. We thus extend and accurately calibrate the VOS model for cosmic strings, including separate terms for energy losses due to loop production and scalar/gauge radiation. By comparing this newly calibrated VOS model with the analogous one for domain walls we quantitatively show that energy loss mechanisms are different for the two types of defects.

description: Increasingly, food security interventions in developing economies are adapting value chain approaches to facilitate the integration of smallholders into high margin value chains. In Kenya, the resurgence of African Indigenous Vegetables due to their medicinal value and rich micronutrients is a case in point. The vegetables are cultivated by smallholders, and the supply has not matched the demand in the high margin markets among urban consumers. Access to such high margin markets necessitates that smallholders gain entry or upgrade into the networks of those buyers who possess considerable control of these value chains. There is limited value chain scholarship on chain governance and its implication for smallholder participation in Kenya. This study investigated how value chain governance influences farmer participation in vegetable markets and food security in Kenya. This study employed exploratory case study design to provide chain architecture, isolate primary actors, their roles, relations, constraints and opportunities for upgrading by smallholders. A mixed method approach involving a multistage sampling technique of 339 respondents was employed to bring to the surface insights on chain architecture, market margins and governance structures and their implications as regards upgrading trajectories for small-scale farmers in Kenya. Thematic analysis was used for data analysis. Spot market relations were found to dominate traditional value chains in rural areas while peri-urban areas exhibited both traditional and coordinated value chains. The value chains are characterised by very weak linkages between upstream actors and downstream partners, where wholesalers and supermarkets play the role of leading firms in traditional and coordinated value chains, respectively. The study recommends the inclusion of famers in market management committees and the establishment of binding contractual arrangements with supermarkets.

description: The government of Ethiopia is aiming to boost sugarcane and ethanol production, together with cogeneration. To achieve this goal, enormous sugarcane production strategies have been undertaken without there being concrete evidence as to theirs benefits or detriments to the welfare of households. Here, we used a computable general equilibrium model and SAM dataset to provide useful insights into this story. The results of the study indicate that the average aggregate income and consumption expenditure of households compared to the baseline scenario are negative, although the magnitude of the loss is small. We further find strong evidence that the average aggregate economic welfare of households has deteriorated by 3.43 percent and we conclude that the strategies that the government has been implementing are detrimental to welfare and devastating. Thus, we suggest that the government should cease sugarcane expansion that succeeds at the expense of food crops and policies that favour the use of marginal and barren lands for upcoming sugarcane projects should instead be implemented.

description: A classical result from 1861 due to Hermite says that every separable equation of degree 5 can be transformed into an equation of the form x^5 + b x^3 + c x + d = 0. Later this was generalized to equations of degree 6 by Joubert. We show that both results can be understood as an explicit analysis of certain covariants of the symmetric groups S_5 and S_6. In case of degree 5, the classical invariant theory of binary forms of degree 5 comes into play whereas in degree 6 the existence of an outer automorphism of S_6 plays an essential role.

Electronic excitations and the tunneling spectra of metallic nanograins

Year: 2003
Subjects: subject: Materials Science (cond-mat.mtrl-sci)

description: Tunneling-induced electronic excitations in a metallic nanograin are classified in terms of {\em generations}: subspaces of excitations containing a specific number of electron-hole pairs. This yields a hierarchy of populated excited states of the nanograin that strongly depends on (a) the available electronic energy levels; and (b) the ratio between the electronic relaxation rate within the nano-grain and the bottleneck rate for tunneling transitions. To study the response of the electronic energy level structure of the nanograin to the excitations, and its signature in the tunneling spectrum, we propose a microscopic mean-field theory. Two main features emerge when considering an Al nanograin coated with Al oxide: (i) The electronic energy response fluctuates strongly in the presence of disorder, from level to level and excitation to excitation. Such fluctuations produce a dramatic sample dependence of the tunneling spectra. On the other hand, for excitations that are energetically accessible at low applied bias voltages, the magnitude of the response, reflected in the renormalization of the single-electron energy levels, is smaller than the average spacing between energy levels. (ii) If the tunneling and electronic relaxation time scales are such as to admit a significant non-equilibrium population of the excited nanoparticle states, it should be possible to realize much higher spectral densities of resonances than have been observed to date in such devices. These resonances arise from tunneling into ground-state and excited electronic energy levels, as well as from charge fluctuations present during tunneling.

description: We studied the macroscopic statistical properties on the freely evolving quasi-elastic hard disk (granular) system by performing a large-scale (up to a few million particles) event-driven molecular dynamics systematically and found that remarkably analogous to an enstrophy cascade process in the decaying two-dimensional fluid turbulence. There are four typical stages in the freely evolving inelastic hard disk system, which are homogeneous, shearing (vortex), clustering and final state. In the shearing stage, the self-organized macroscopic coherent vortices become dominant. In the clustering stage, the energy spectra are close to the expectation of Kraichnan-Batchelor theory and the squared two-particle separation strictly obeys Richardson law.

Large Direct CP Violation in B -> phi phi Xs Decays
Creators: name: Hazumi, Masashi
Publisher: name: arXiv
Year: 2003
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: We present a novel method to search for a new CP-violating phase in b -> ss~ss~s transition using B -> phi phi Xs decays, where Xs represents a final state with a specific strange flavor such as K+/-, K*+/-, or K+/-pi-/+. Direct CP violation can be enhanced due to an interference between an amplitude beyond the standard model (SM) and the SM decay amplitude through the eta_c resonance. We find that the CP asymmetry can be as large as 0.4 within the present experimental bounds on the b -> ss~s transition. These decays provide a very clean experimental signature and the background is expected to be small in particular at e+e- B factories. A simulation study for the B+/- -> phi phi K+/- decay shows that the statistical significance of CP violation can exceed 5 standard deviations with 10^9 B mesons.

Effects of Animal Traction of Subsistence Level Farming in Bourkina Fasso: Production Function Analysis
Creators: name: Pyeong-Mu, Bark

Publisher: name: Unknown
Year: 1988
Subjects: Production Economics

description: This study was concerned with the following two major hypotheses within the setting of subsistence level farming in Bourkina Fasso : the introduction of an animal traction (AT) program has a positive effect on the productivity per unit land area, and the AT program, known as a labor-saving technolo­gy, is also an innovative technology. The study used a functional analysis. From the analysis of results the author concludes: 1. In the case of corn and peanuts, labor, capital and animal traction variables are statistically significant and positive. In the case of millet production, the labor variable is only significant, while in the case of sorghum production the capital variable is most significant, 2. The results show some substitutability between millet and sorghum crop productions, 3. The translog production function estimates for millet suggest several implications such as there exist different levels of technology use between AT and non-AT farms, and there exist not only different shapes of production functions but also different input factor orientations between AT and non-AT farms, 4. Within the context of translog production function in the case of millet production, the results indicate that the production process of non-AT farms seems to be heavily dependent upon labor input and that of AT farms relies on labor, capital and animal power input, and 5. The study draws an inference that in the case of millet production, an AT program may be considered an innovative technology.

description: Networks can now process data as well as transporting it; it follows that they can support multiple services, each requiring different key performance indicators (KPIs). Because of the former, it is critical to efficiently allocate network and computing resources to provide the required services, and, because of the latter, such decisions must jointly consider all KPIs targeted by a service. Accounting for newly introduced KPIs (e.g., availability and reliability) requires tailored models and solution strategies, and has been conspicuously neglected by existing works, which are instead built around traditional metrics like throughput and latency. We fill this gap by presenting a novel methodology and resource allocation scheme, named OKpi, which enables high-quality selection of radio points of access as well as VNF (Virtual Network Function) placement and data routing, with polynomial computational complexity. OKpi accounts for all relevant KPIs required by each service, and for any available resource from the fog to the cloud. We prove several important properties of OKpi and evaluate its performance in two real-world scenarios, finding it to closely match the optimum.

description: The way of selling has evolved over the last decade, mostly driven by the swift profession of digital technologies and social changes. Inside sales have grown significantly due to the high costs of traditional field sales and advances in information and communication technologies (ICTs). The COVID-19 pandemic has further accelerated this shift, compelling selling organizations to maximize opportunities from both new prospects and existing customers through sales that are conducted remotely or virtually. As a fundamental task in the initial prospecting stage of the inside sales process, lead scoring evaluates and ranks leads based on their conversion likelihood to improve sales success. Despite the importance of lead scoring tasks in inside sales, there is a lack of research studying the current state of lead scoring models and how to improve overall sales performance by enhancing the efficacy of lead scoring models. This dissertation investigates the evolution and optimization of lead scoring tasks in the business-to-business (B2B) inside sales context, focusing on transitioning from traditional to predictive lead scoring models. This doctoral dissertation aims to: (1) Summarize critical gaps in the current understanding of lead scoring models, including their advantages, disadvantages, and impact on sales performance. (2) Identify and validate the key factors for a potential buyer's purchase decision-making process. (3) Optimize lead scoring outcomes through predictive modeling. By employing a systematic literature review, empirical validation, and the development and implementation of a novel predictive lead scoring model, this dissertation demonstrates the potential of data-driven predictive analytics using datasets from online surveys and service industries and offers a comprehensive framework for improving inside sales performance. The key contributions of this doctoral dissertation include the integration of a seller-centric marketing sales funnel with a lead-centric purchase decision-making process, providing a holistic approach to predictive lead scoring. The findings demonstrate that incorporating insights from leads' profiles into predictive models can significantly enhance sales performance. This research not only aids industry practitioners in refining their lead management strategies but also advances academic understanding of the role of predictive analytics in B2B inside sales success.

description: We construct two reduced quantum theories for the Oppenheimer-Snyder model, respectively taking the point of view of the comoving and the exterior stationary observer, using affine coherent states quantization. Investigations of the quantum corrected dynamics reveal that both observers can see a bounce, although for the exterior observer certain quantization ambiguities have to be chosen correctly. The minimal radius for this bounce as seen from the stationary observer is then shown to always be outside of the photon sphere. Possible avenues to lower this minimal radius and reclaim black holes as an intermediate state in the collapse are discussed. We demonstrate further that switching between the observers at the level of the quantum theories can be achieved by modifying the commutation relations.

description: We propose a simplified version of self-interaction corrected local spin-density (SIC-LSD) approximation, based on multiple scattering theory, which implements self-interaction correction locally, within the KKR method. The multiple scattering aspect of this new SIC-LSD method allows for the description of crystal potentials which vary from site to site in a random fashion and the calculation of physical quantities averaged over ensembles of such potentials using the coherent potential approximation (CPA). This facilitates applications of the SIC to alloys and pseudoalloys which could describe disordered local moment systems, as well as intermediate valences. As a demonstration of the method, we study the well-known $α$-$γ$ phase transition in Ce, where we also explain how SIC operates in terms of multiple scattering theory.

description: This paper introduces a novel physical-layer method labelled as Multi-Modal Concurrent Transmission (MMCT) for efficient transmission of multiple data streams with different reliability-latency performance requirements. The MMCT arranges data from multiple streams within a same physical-layer transport block wherein stream-specific modulation and coding scheme (MCS) selection is combined with joint mapping of modulated codewords to Multiple-Input Multiple-Output spatial layers and frequency resources. Mapping to spatial-frequency resources with higher Signal-to-Noise Ratios (SNRs) provides the required performance boost for the more demanding streams. In tactile internet applications, wherein haptic feedback/actuation and audio-video streams flow in parallel, the method provides significant SNR and spectral efficiency enhancements compared to conventional 3GPP New Radio (NR) transmission methods.

description: We construct d=4,N=1 orientifolds of Gepner models with just the chiral spectrum of the standard model. We consider all simple current modular invariants of c=9 tensor products of N=2 minimal models. For some very specific tensor combinations, and very specific modular invariants and orientifold projections, we find a large number of such spectra. We allow for standard model singlet (dark) matter and non-chiral exotics. The Chan-Paton gauge group is either U(3) x Sp(2) x U(1) x U(1) or U(3) x U(2) x U(1) x U(1). In many cases the standard model hypercharge U(1) has no coupling to RR 2-forms and hence remains massless; in some of those models the B-L gauge boson does acquire a mass.

description: This paper deals with the distributed and boundary controllability of the so called Leray-$α$ model. This is a regularized variant of the Navier-Stokes system ($α$ is a small positive parameter) that can also be viewed as a model for turbulent flows. We prove that the Leray-$α$ equations are locally null controllable, with controls bounded independently of $α$. We also prove that, if the initial data are sufficiently small, the controls converge as $α\to 0^+$ to a null control of the Navier-Stokes equations. We also discuss some other related questions, such as global null controllability, local and global exact controllability to the trajectories, etc.

description: We present a summary of recent constraints on the value of the fine-structure constant at the epoch of decoupling from the recent observations made by the Wilkinson Microwave Anisotropy Probe (WMAP) satellite. Within the set of models considered, a variation of the value of $α$ at decoupling with respect to the present-day value is now bounded to be smaller than 2% (6%) at 95% confidence level. We point out that the existence of an early reionization epoch as suggested by the above measurements will, when more accurate cosmic microwave background polarization data is available, lead to considerably tighter constraints. We find that the tightest possible constraint on $α$ is about $0.1 %$ using CMB data alone--tighter constraints will require further (non-CMB) priors.

description: The nonextremal Kerr black holes have been considered to be holographically dual to two-dimensional (2D) conformal field theories (CFTs). In this paper, we extend the holography to the case of an asymptotically anti--de Sitter (AdS) rotating charged black holes in $f$($T$) gravity, where $f(T) = T + αT^2$, where $α$ is a constant. We find that the scalar wave radial equation at the near-horizon region implies the existence of the 2D conformal symmetries. We note that the $2π$ identification of the azimuthal angle $ϕ$ in the black hole line element, corresponds to a spontaneous breaking of the conformal symmetry by left and right temperatures $T_{L}$ and $T_{R}$, respectively. We show that choosing proper central charges for the dual CFT, we produce exactly the macroscopic Bekenstein-Hawking entropy from the microscopic Cardy entropy for the dual CFT. These observations suggest that the rotating charged AdS black hole in $f$($T$) gravity is dual to a 2D CFT at finite temperatures $T_{L}$ and $T_{R}$ for a specific value of mass $M$, rotational, charge, and $f$($T$) parameters, $Ω$, $Q$, and $|α|$, respectively.

description: Despite growing tensions over China’s military build-up and modernization, there is little understanding of China’s defense budget. Published estimates vary implausibly from one quarter of the USA’s defense budget to near parity, and there are very few attempts to understand how its size or composition has changed over time. This paper uses index number techniques to quantify China’s real defense spending over time and relative to the USA. I construct price deflators and show that overall growth has been slower than thought, but also that there has been extremely rapid growth in real military equipment spending that has transformed China’s defense forces. China’s real defense purchasing power is also found to be 60% larger than commonly used market exchange rate estimates and equal to 59% of the USA’s defense budget in 2021. Notwithstanding the rapid growth in equipment, the high relative purchasing power mostly reflects China’s far larger number of active personnel.

description: Digital tools may help to study socioeconomic aspects of agricultural development that are difficult to measure such as the effects of new technologies, policies and practices on the intra-household allocation of time. As new technologies, policies and practices may target different crops and tasks, they can affect time-use of men, women, boys and girls differently. Development strategies that overlook such effects can fail or have negative consequences for vulnerable household members. In this paper, the effects of agricultural mechanization on time-use in smallholder farming households in Zambia were investigated. For this, a novel data collection method was used: a pictorial smartphone application that allows real-time recording of time-use to eliminate recall bias. Existing studies analyzing intra-household allocation of resources often focus on adult males and females. This study paid particular attention to boys and girls. The study also addressed seasonal variations. For data analysis, compositional data analysis was used, which yields higher accuracy than univariate analysis by accounting for the co-dependence and sum constraint of time-use data. The study found that women benefit relatively more from mechanization with regard to time-use during land preparation, which leads to gender differentiation; for households using manual labor, such differentiation was not found. There was some evidence that the time "saved" is used for off-farm and domestic work. No negative second-round effects (such as higher labor burdens) during weeding and harvesting/processing and no negative effects on children were found. The study debunks some myths related to gender roles in African smallholder agriculture, opens the field to more studies on technology adoption and time-use and suggests that gender roles are changing with agricultural transformation.

description: A tremendous international effort is currently dedicated to observing the so-called primordial B modes of the Cosmic Microwave Background (CMB) polarisation. If measured, this faint signal imprinted by the primordial gravitational wave background, would be an evidence of the inflation epoch and quantify its energy scale, providing a rigorous test of fundamental physics far beyond the reach of accelerators. At the unprecedented sensitivity level that the new generation of CMB experiments aims to reach, every uncontrolled instrumental systematic effect will potentially result in an analysis bias that is larger than the much sought-after CMB B-mode signal. The absolute calibration of the polarisation angle is particularly important in this sense, as any associated error will end up in a leakage from the much larger E modes into B modes. The Crab nebula (Tau A), with its bright microwave synchrotron emission, is one of the few objects in the sky that can be used as absolute polarisation calibrators. In this communication, we review the best current constraints on its polarisation angle from 23 to 353 GHz, at typical angular scales for CMB observations, from WMAP, IRAM XPOL, Planck and NIKA data. We will show that these polarisation angle measurements are compatible with a constant angle and we will present a study of the uncertainty on this mean angle, making different considerations on how to combine the individual measurement errors. For each of the cases, the potential impact on the CMB B-mode spectrum will be explored.

description: The dairy sector in Kenya is one of the largest and most developed in Sub-Saharan Africa, accounting for four percent of its gross domestic product. Despite high production volumes, the sector is still dominated by smallholder farmers who rely on livestock for income and food security. Dairy farmers face a number of barriers to increased profitability, including animal diseases, lack of access to artificial insemination and other veterinary services, high costs of improved technologies, such as silage equipment, inadequate access to markets, poor rural infrastructure and unsteady supply of quality animal fodder. The Smallholder Dairy Commercialisation Programme (SDCP) was funded by the International Fund for Agricultural Development (IFAD) and implemented by the Government of Kenya from 2005 – 2015. It was designed to reach 600 dairy groups (24,000 smallholder dairy farmers) in nine counties. SDCP provided training to dairy farmers to build their enterprise, managerial and organisational skills. Aside from training, the programme also aimed to enhance dairy farming productivity and reduce production costs through demonstration, field days and grants. To strengthen market linkages, SDCP invested in improving road infrastructure and conducted additional training on milk-handling practices and value-added opportunities. The programme identified three main areas where barriers to improving dairy income potentially operate: dairy group activities, household production and market intermediaries. Programme designers hypothesised that increasing net dairy income for smallholder farmers can occur through four primary contextual factors (1) increasing milk production; (2) increasing milk prices; (3) decreasing the costs of producing milk; and (4) decreasing the transaction costs of participation in input and output markets. They assumed that increased net income will lead to improved food security and increased participation by women and marginalised communities.
