description: Most galaxy evolutionary models require quasar feedback to regulate star formation in their host galaxies. In particular, at high redshift, models expect that feedback associated with quasar-driven outflows is so efficient that the gas in the host galaxy is largely swept away or heated up, hence suppressing star formation in massive galaxies. We observationally investigate this phenomenon by using VLT-SINFONI integral field spectroscopy of the luminous quasar 2QZJ002830.4-281706 at z=2.4. The spectra sample the optical emission lines redshifted into the near-IR. The [OIII]5007 emission-line kinematics map reveals a massive outflow on scales of several kpc. The detection of narrow Halpha emission reveals star formation in the quasar host galaxy, with SFR=100 Msun/yr. However, the star formation is not distributed uniformly, but is strongly suppressed in the region with the highest outflow velocity and highest velocity dispersion. This result indicates that star formation in this region is strongly quenched by the quasar outflow, which is cleaning the galaxy disk of its molecular gas. This is one of the first direct observational proofs of quasar feedback quenching the star formation at high redshift.

Measuring Nutrition and Food Literacy in Adults: A Systematic Review and Appraisal of Existing Measurement Tools
Creators: name: (:Unkn) Unknown
Publisher: name: My University
Year: 2018

description: Background: Nutrition literacy (NL) and food literacy (FL) have emerged as key components in the promotion and maintenance of healthy dietary practices. However, a critical appraisal of existing tools is required to advance the operationalization and measurement of these constructs using instruments that demonstrate sound validity and reliability. Methods: Electronic databases were searched in January and July 2016, January 2017, and March 2018 for publications detailing the development and/or testing of NL or FL instruments. Instruments' psychometric properties were assessed using a structured methodological framework. We identified 2,563 new titles and abstracts, and short-listed 524 for full review. The extent to which key domains of NL were included in each measure was examined. Key Results: Thirteen instruments assessing NL underwent full evaluation; seven from the United States, and one each from Australia, Norway, Switzerland, Italy, Hong Kong, and Japan. Measures targeted general Spanish-, Italian-, or Cantonese-speaking adults; primary care patients, parent, and populations with breast cancer. Instruments ranged from 6 to 64 items, and they predominantly assessed functional NL rather than broader domains of NL. Substantial variation in methodological rigor was observed across measures. Discussion: Multidimensional and psychometrically sound measures that capture broader domains of NL and assess FL are needed. Plain Language Summary: This review systemically compiles, and critically appraises 13 existing measures that assess nutrition literacy and food literacy in an adult population. Substantial variation in methodological rigor was found across the measures, and most tools assessed nutrition literacy rather than food literacy. Findings from this current review may be useful to guide development of future measures that comprehensively capture nutrition literacy and food literacy.

Learning from failure in conservation: Individual, team, and organizational dynamics
Creators: name: Catalano, Allison Stayner
Publisher: name: Imperial College London

description: Conservation aims to ensure the persistence of biodiversity despite myriad and mounting threats at the intersection of biological processes and socio-economic activity, and many efforts have struggled to achieve success. Failure is inevitable in the complex contexts in which conservation initiatives take place and yet is largely underexamined. Reasons for this shortcoming are multidimensional, encompassing behavioral and cognitive limitations at the individual, group, and organizational levels. Conservation is recognized as primarily about people and the choices they make, but there is a gap in what we know about how conservation professionals themselves as people operating within teams and organizations learn from and manage failure. My research investigates the current state of failure management in conservation, building upon existing literature in organizational learning and drawing insights from other disciplines to identify ways for conservation to more effectively learn from failure. To do this, I first conduct a literature review to investigate factors contributing to a lack of learning from failure and success in conservation. I find that failure reports are rare and largely unstandardized, and human factors such as stakeholder relationships were the most commonly cited cause of project failure. I then carry out a strategic review of organizational learning literature to provide an inter-disciplinary synthesis of thinking and practice of failure management. Armed with these broad insights, I delve into individual intentions to engage in learning from failure behaviors, finding that social norms, psychological safety, organizational support, and leader behavior play important roles in facilitating learning from failure. To place these individual motivations into a broader context, I then investigate barriers and enabling conditions for learning from failure through a multimethod qualitative study. Finally, I synthesize my findings and provide an operational model and actionable steps going forward. Providing the first empirical examination of failure in conservation, this thesis highlights both shortfalls in failure management in conservation and, more importantly, opportunities to create a learning transformation going forward.

description: Introduction Antibiotic usage for COVID-19 patients was uncertain in the early phase of the pandemic. Objectives: To determine the prevalence of antibiotic usage and factors affecting antibiotic usage in COVID-19 patients.   Methodology This is a cross-sectional study which reviewed medical records of COVID-19 Malaysian patients aged 12 and above who were admitted to all COVID-19 hospitals in from February to April 2020. Binary logistic regression analysis was performed to determine factors associated with antibiotic use in COVID-19 patients. Results Of 4043 cases, the majority of the patients were male (65.0%), non-smoker (87.6%), and had at least one comorbid (37.0%) with a median age of 38 years (IQR: 38). The prevalence of antibiotic usage was 16.5% with 4.7% of them prescribed with two or more types. The most frequent antibiotic prescribed were Co-Amoxiclav (10.6%) followed by Ceftriaxone (3.4%), Piperacillin/Tazobactam (3.8%), Azithromycin (2.3%), and Meropenem (2.0%). Higher odds of antibiotic usage were seen in male patients who had comorbidities, clinical severity of stage two to five, out-of-range inflammatory blood parameters (white blood cells, neutrophils, lymphocytes and C-reactive protein), use of corticosteroid and admission to the intensive care unit. Conclusion The prevalence of antibiotic usage at the early phase of COVID-19 pandemic was 16.5%, which is relatively low compared to other countries (58 to 71%). Significant factors influencing the odds of antibiotic usage were consistent with findings from other studies. This observation showed that clinicians rationalized the antibiotic usage based on clinical assessment, supported by relevant laboratory parameters.

description: Nitrogen-doped graphene was recently synthesized and was reported to be a catalyst for hydrogen dissociative adsorption under a perpendicular applied electric field (F). In this work, the diffusion of H atoms on N-doped graphene, in the presence and absence of an applied perpendicular electric field, is studied using density functional theory. We demonstrate that the applied field can significantly facilitate the binding of hydrogen molecules on N-doped graphene through dissociative adsorption and diffusion on the surface. By removing the applied field the absorbed H atoms can be released efficiently. Our theoretical calculation indicates that N-doped graphene is a promising hydrogen storage material with reversible hydrogen adsorption/desorption where the applied electric field can act as a switch for the uptake/release processes.

Socioeconomic status (SES) predicts health, wellbeing, and cognitive ability, including executive function (EF). A body of recent work has shown that childhood SES is positively related to EF, but it is not known whether this disparity grows, diminishes or holds steady over development, from childhood through adulthood. We examined the association between childhood SES and EF in a sample ranging from 9–25 years of age, with six canonical EF tasks. Analyzing all of the tasks together and in functionally defined groups, we found positive relations between SES and EF, and the relations did not vary by age. Analyzing the tasks separately, SES was positively associated with performance in some but not all EF measures, depending on the covariates used, again without varying by age. These results add to a growing body of evidence that childhood SES is associated with EF abilities, and contribute novel evidence concerning the persistence of this association into early adulthood.

description: Ultrafast dynamics of graphite is investigated by time-resolved photoemission spectroscopy. We observe spectral features of direct photoexcitations, non-thermal electron distributions, and recovery dynamics occurring with two time scales having distinct pump-power dependences. Additionally, we find an anomalous increase of the spectral intensity around the Fermi level, and we attribute this to spectral broadenings due to coupled optical phonons in the transient. The fingerprints of the coupled optical phonons occur from the temporal region where the electronic temperature is still not definable. This implies that there is a mechanism of ultrafast-and-efficient phonon generations beyond a two-temperature model.

description: We propose a solution to the image deconvolution problem where the convolution kernel or point spread function (PSF) is assumed to be only partially known. Small perturbations generated from the model are exploited to produce a few principal components explaining the PSF uncertainty in a high dimensional space. Unlike recent developments on blind deconvolution of natural images, we assume the image is sparse in the pixel basis, a natural sparsity arising in magnetic resonance force microscopy (MRFM). Our approach adopts a Bayesian Metropolis-within-Gibbs sampling framework. The performance of our Bayesian semi-blind algorithm for sparse images is superior to previously proposed semi-blind algorithms such as the alternating minimization (AM) algorithm and blind algorithms developed for natural images. We illustrate our myopic algorithm on real MRFM tobacco virus data.

description: © 1967-2012 IEEE. This paper focuses on the routing algorithm for the communications between vehicles and places in urban vehicular ad hoc networks. As one of the basic transportation facilities in an urban setting, buses periodically run along their fixed routes and cover many city streets. The trajectory of bus lines can be seen as a submap of a city. Based on the characters of bus networks, we propose a bus-trajectory-based street-centric (BTSC) routing algorithm, which uses buses as the main relay to deliver messages. In BTSC, we build a routing graph based on the trajectories of bus lines by analyzing the probability of bus appearing on every street. We propose two novel concepts, i.e., the probability of street consistency and the probability of path consistency, which are used as metrics to determine routing paths for message delivery. This aims to choose the best path with higher density of busses and lower probability of transmission direction deviating from the routing path. In order to improve the bus forwarding opportunity, we design a bus-based forwarding strategy with ant colony optimization to find a reliable and a steady multihop link between two relay buses in order to decrease the end-to-end delay. The BTSC makes improvements in the selection of routing paths and a strategy of message forwarding. Simulation results show that our proposed routing algorithm has a better performance in terms of the transmission ratio, transmission delay, and adaptability to different networks.

description: There is now a growing body of literature that indicates that stress can initiate inflammatory processes, both in the periphery and brain; however, the spatiotemporal nature of this response is not well characterized. Therefore, the aim of this study is to examine the effects of an acute psychological stress on changes in mRNA and protein levels of inflammatory mediators across a wide temporal range, in key corticolimbic brain regions regulating stress (amygdala, hippocampus, hypothalamus, prefrontal cortex). mRNA levels of inflammatory mediators were analyzed immediately following 30 minutes or 2 hours of acute restraint stress and protein levels were examined 0 hours through 24 hours post termination of 2 hours of acute restraint stress using multiplex and ELISA methods. While the results are not completely consistent across all methods utilized, the results show a general increase in inflammatory mediators in circulation and in the amygdala and decrease in the prefrontal cortex.

description: © 2018 John Wiley & Sons, Ltd. With the ever-growing diversity of devices and applications that will be connected to 5G networks, flexible and agile service orchestration with acknowledged quality of experience (QoE) that satisfies the end user's functional and quality-of-service (QoS) requirements is necessary. Software-defined networking (SDN) and network function virtualization (NFV) are considered key enabling technologies for 5G core networks. In this regard, this paper proposes a reinforcement learning–based QoS/QoE-aware service function chaining (SFC) scheme in SDN/NFV-enabled 5G slices. First, it implements a lightweight QoS information collector based on the Link Layer Discovery Protocol, which works in a piggyback fashion on the southbound interface of the SDN controller, to enable QoS-awareness. Then, a deep Q-network–based orchestration agent is designed to support SFC in the context of NFV. The agent takes into account the QoE and QoS as key aspects to formulate the reward so that it is expected to maximize QoE while respecting QoS constraints. The experiment results show that the proposed framework exhibits good performance in QoE provisioning and QoS requirements maintenance for SFC in dynamic network environments.

description: © 2018 The Author(s). Background: While several JavaScript packages for visualizing phylogenetic trees exist, most are best characterized as frameworks that are designed with a specific set of tasks in mind. Extending such packages to use cases that are not available as features often ends up being difficult. Moreover, existing packages tend to produce standalone widgets that are not designed to serve as middleware, as opposed to flexible tools that can integrate with other components of an application. Results: phylotree.js is a library that extends the popular data visualization framework d3.js, and is suitable for building JavaScript applications where users can view and interact with phylogenetic trees. The effects of such interactions can be captured and communicated to other package components, making it possible to engineer complex and responsive applications that include phylogenetic trees. phylotree.js implements several abstractions in addition to features, and comes with a documented application programming interface, thus promoting interoperability and extensibility. Example applications include a tool to visualize and annotate phylogenetic trees, a web application for comparative sequence analysis, a structural viewer that interacts with a large phylogenetic tree, and an interactive tanglegram. Conclusions:phylotree.js is a useful tool and application module for a variety of computational biology software applications. The code is available on Github and is released under the MIT license.
Global polarization of Λ hyperons in Au + Au collisions at sNN =200 GeV

description: © 2018 American Physical Society. Global polarization of Λ hyperons has been measured to be of the order of a few tenths of a percentage in Au+Au collisions at sNN = 200 GeV, with no significant difference between Λ and Λ. These new results reveal the collision energy dependence of the global polarization together with the results previously observed at sNN = 7.7-62.4 GeV and indicate noticeable vorticity of the medium created in noncentral heavy-ion collisions at the highest Relativistic Heavy Ion Collider collision energy. The signal is in rough quantitative agreement with the theoretical predictions from a hydrodynamic model and from a multi-phase transport model. The polarization is larger in more peripheral collisions, and depends weakly on the hyperon's transverse momentum and pseudorapidity ηH within |ηH|<1. An indication of the polarization dependence on the event-by-event charge asymmetry is observed at the 2σ level, suggesting a possible contribution to the polarization from the axial current induced by the initial magnetic field.

description: To perform imaging observation of optically red objects such as high redshift quasars and brown dwarfs, the Center for the Exploration of the Origin of the Universe (CEOU) recently developed an optical CCD camera, Camera for QUasars in EArly uNiverse(CQUEAN), which is sensitive at 0.7-1.1 um. To enable observations with long exposures, we developed an auto-guiding system for CQUEAN. This system consists of an off-axis mirror, a baffle, a CCD camera, a motor and a differential decelerator. To increase the number of available guiding stars, we designed a rotating mechanism for the off-axis guiding camera. The guiding field can be scanned along the 10 acrmin ring offset from the optical axis of the telescope. Combined with the auto-guiding software of the McDonald Observatory, we confirmed that a stable image can be obtained with an exposure time as long as 1200 seconds.

Non-stationary adaptive signal prediction with error bounds
Creators: name: Korale, Asoka J.M.
Publisher: name: Imperial College London
Year: 2023

description: A fundamental assumption in autoregressive (AR) modelling is wide sense stationary of the signal. However in practice this assumption may not be satisfied, as the statistics of the signal may be inherently non-stationary. As a consequence, the true AR parameters would be time varying. Therefore if an adaptive predictor which minimises the mean square prediction error was used to estimate the AR parameters the resulting estimates would be inaccurate. In this work, we depart from the typical assumption of stationarity and examine time varying AR parameter estimation. To account for time dependence a framework based upon a single sample prediction is employed with constraints on the error of prediction. These constraints are introduced in order to bound the prediction error and are used to produce sequential and block-based adaptive predictors. In this context we analyse the effect of using fixed-point iterative procedures on the update equations of the adaptive algorithms. The non-stationary nature of the AR parameters is manifest and taken care of at the next stage. The AR parameters so obtained are time varying, making efficient signal representation for coding or compression applications difficult. Thus, a new method for the analysis of a non-stationary process is introduced in the context of the “Endomorphic” model. In this model piecewise constant parameters are obtained, when the parameters themselves of an AR process are subject to a multistage AR analysis. This approach is an analysis by synthesis technique where the prediction is formulated as a constrained optimisation problem, which matches the prediction error term to a desired sequence at every sample. We then apply the updates derived for single and multiple constraints on the prediction error, and study the behaviour of the multistage parameters. We finally consider the case of an HR predictor with a bounded prediction error. In this case, however, the sequential prediction is based on a regression vector of the predicted signal itself. This closed loop prediction, when applied to speech, enables synthesis using a well-defined prediction error signal. The scheme analyses the speech signal into an excitation and a set of AR parameters conditioned on certain a-priori bounds on the prediction error. In this approach, the excitation signal may be used for the determination of the pitch period and glottal closure instants.

Beam Energy Dependence of Jet-Quenching Effects in Au+Au Collisions at sNN =7.7, 11.5, 14.5, 19.6, 27, 39, and 62.4 GeV

description: © 2018 American Physical Society. We report measurements of the nuclear modification factor RCP for charged hadrons as well as identified π+(-), K+(-), and p(p) for Au+Au collision energies of sNN=7.7, 11.5, 14.5, 19.6, 27, 39, and 62.4 GeV. We observe a clear high-pT net suppression in central collisions at 62.4 GeV for charged hadrons which evolves smoothly to a large net enhancement at lower energies. This trend is driven by the evolution of the pion spectra but is also very similar for the kaon spectra. While the magnitude of the proton RCP at high pT does depend on the collision energy, neither the proton nor the antiproton RCP at high pT exhibit net suppression at any energy. A study of how the binary collision-scaled high-pT yield evolves with centrality reveals a nonmonotonic shape that is consistent with the idea that jet quenching is increasing faster than the combined phenomena that lead to enhancement.
Catastrophic failure of large storage facilities, containing cryogenic fluids
Creators: name: Su, Rochmadi
Publisher: name: Imperial College London
Year: 2023

description: The sudden release of cryogenic liquid resulting from Catastrophic Tank Failure (CTF) and its interaction with vertical bunds has been investigated theoretically. Once the tank wall has ruptured, the phenomenon of CTF itself is regarded as a collapse of a vertical, squat liquid column under its own weight. The resulting flow rushes to and collides with a vertical cylindrical bund, coaxial with the liquid column, and returns to the column axis as a strong hydraulic shock. If the bund is low, overflow occurs. The flow description is based on Shallow Water theory, and the governing equations are solved by the Method of Characteristics. Consistency of the results has been checked against the principle of mass and energy conservation. In preparation, the first part of the work is concerned with re-investigation of non-boiling liquid release, which has already been examined theoretically and experimentally by several authors. The calculated energy loss at the shock agrees within 1 % with the energy discrepancy, defined as the calculated total energy content at any time level less the total theoretical initial energy content. The calculated amount of overflowing liquid also agrees within 1 % with the mass discrepancy ( the calculated total mass less the total theoretical initial mass ). The maximum shock height at the bund is equal to that estimated previously (Kleyn, 1983), but such work under estimated the amount of overflowing liquid. The results of this study also roughly agree with the experimental results (Greenspan and Johansson, 1981; Sharifi, 1987). Cryogenic liquid release is described in the second part of the work. As cryogenic liquids boil vigorously on contact with the ground, the proposed model considers that the cryogenic liquid flow contains vapour, which forms a two-phase layer on the ground surface. The two-phase layer thick ness depends on: boiling rate, horizontal flow velocity, column height and diameter, physical properties of liquid and vapour, and the vapour motion in the flow. The flow region is divided into: non-boiling, density-change and vapour-release regions, with each region having its own governing equations. This work only gives general description of the two-phase, unconfined and confined flow. Further theoretical and experimental investigations are needed. The theoretically predicted propagation velocity of the moving front is around 1.7-1.83. Comparison with results for non-boiling liquid flow has shown that for cryogenic liquid flow, the shock height at the bund and the amount of overflowing liquid are higher than for non-boiling liquid flow. It is concluded that the model for non-boiling flow cannot be used to describe appropriately cryogenic liquid flow.

description: This project uses Gilles Deleuze and Félix Guattari's concept of the minor cinema to argue for a contemporary political mode of film that critiques dominant or majoritarian ideologies. I argue that these 'modern political films' perform this critique by rupturing the sensory-motor schemata that make up official times and create a space for everyday life and labor to emerge on screen. While political theorists such as Carl Schmitt argue proper politics necessitate oppositional conflict and dialectical progression, a classical model based on the opposition between ultimately Other subjects, modern political films challenge this notion by fragmenting the concept of an appropriate subject and revealing the networks that contribute to and create modern, multifaceted subjects. I locate modern political films in four global contexts: Algeria, Iran, China, and the United States. While the political circumstances of each context differ greatly, the filmmakers I examine turn to a slower pace or use of cinematic time that resists narrative conclusion to address political, economic, and social issues affecting populations within these global locations. Through this slower pace, these directors also address the biopolitical concerns of the subjects they depict: intolerable laws, ideologies, and economic forces that structure or otherwise control how individuals live their lives.

description: We analyze general enough models of repeated indirect measurements in which a quantum system interacts repeatedly with randomly chosen probes on which Von Neumann direct measurements are performed. We prove, under suitable hypotheses, that the system state probability distribution converges after a large number of repeated indirect measurements, in a way compatible with quantum wave function collapse. Similarly a modified version of the system density matrix converges. We show that the convergence is exponential with a rate given by some relevant mean relative entropies. We also prove that, under appropriate rescaling of the system and probe interactions, the state probability distribution and the system density matrix are solutions of stochastic differential equations modeling continuous-time quantum measurements. We analyze the large time convergence of these continuous-time processes and prove convergence.

description: © American Sociological Association 2018. Randomized experiments on a network often involve interference between connected units, namely, a situation in which an individual’s treatment can affect the response of another individual. Current approaches to deal with interference, in theory and in practice, often make restrictive assumptions on its structure—for instance, assuming that interference is local—even when using otherwise nonparametric inference strategies. This reliance on explicit restrictions on the interference mechanism suggests a shared intuition that inference is impossible without any assumptions on the interference structure. In this paper, we begin by formalizing this intuition in the context of a classical nonparametric approach to inference, referred to as design-based inference of causal effects. Next, we show how, always in the context of design-based inference, even parametric structural assumptions that allow the existence of unbiased estimators cannot guarantee a decreasing variance even in the large sample limit. This lack of concentration in large samples is often observed empirically, in randomized experiments in which interference of some form is expected to be present. This result has direct consequences for the design and analysis of large experiments—for instance, in online social platforms—where the belief is that large sample sizes automatically guarantee small variance. More broadly, our results suggest that although strategies for causal inference in the presence of interference borrow their formalism and main concepts from the traditional causal inference literature, much of the intuition from the no-interference case do not easily transfer to the interference setting.
"Leading blob" model in a stochastic acceleration scenario: the case of the 2009 flare of Mkn~501

description: Evidence for very hard, intrinsic $γ$-ray source spectra, as inferred after correction for absorption in the extragalactic background light (EBL), has interesting implications for the acceleration and radiation mechanisms acting in blazars. A key issue so far has been the dependance of the hardness of the $γ$-ray spectrum on different existing EBL models. The recent {\it Fermi} observations of Mkn~501 now provide additional evidence for the presence of hard intrinsic $γ$-ray spectra independent of EBL uncertainties. Relativistic Maxwellian-type electron energy distributions that are formed in stochastic acceleration scenarios offer a plausible interpretation for such hard source spectra. Here we show that the combined emission from different components with Maxwellian-type distributions could in principle also account for more softer and broader, power law-like emission spectra. We introduce a "leading blob" scenario, applicable to active flaring episodes, when one (or few) of these components become distinct over the "background" emission, producing hard spectral features and/or hardening of the observed spectra. We show that this model can explain the peculiar high-energy characteristics of Mkn~501 in 2009, with evidence for flaring activity and strong spectral hardening at the highest $γ$-ray energies.

description: © 2018 Yu, Shafto, Bonawitz, Yang, Golinkoff, Corriveau, Hirsh-Pasek and Xu. For infants and young children, learning takes place all the time and everywhere. How children learn best both in and out of school has been a long-standing topic of debate in education, cognitive development, and cognitive science. Recently, guided play has been proposed as an integrative approach for thinking about learning as a child-led, adult-assisted playful activity. The interactive and dynamic nature of guided play presents theoretical and methodological challenges and opportunities. Drawing upon research from multiple disciplines, we discuss the integration of cutting-edge computational modeling and data science tools to address some of these challenges, and highlight avenues toward an empirically grounded, computationally precise and ecologically valid framework of guided play in early education.

Dos veces mujer: génesis del documental feminista en América Central

description: Patricia Howell es una cineasta costarricense consagrada al militantismo por la lucha de igualdad de género. Su trabajo fílmico así como su militancia sobrepasan las fronteras nacionales contando hoy día con una vasta carrera internacional. Sin embargo, en sus inicios como cineasta, se vio confrontada a una profesión practicada por hombres, es así como Howell tuvo la tarea de abrir el camino a un cine por y para las mujeres. Centrándonos en el análisis de su opera prima, Dos veces mujer (1982), el presente artículo pretende demostrar el rol pionero que ha ejercido Patricia Howell en la región centroamericana y la construcción de una cinematografía comprometida con la lucha por la igualdad de género. Para ello nos interrogaremos ¿en qué medida este documental sienta las bases de una cinematografía feminista en la región? y ¿qué aportes histórico sociales brinda el documental en materia de estudios de género?

description: La economía feminista ha ido construyendo críticas y reflexiones en todos los campos temáticos de la economía, en los tres niveles de análisis (micro, meso y macro), y en relación con las distintas escuelas de pensamiento. En este artículo no se pretende describirlas distintas escuelas del pensamiento de la economía feminista, sino apoyarnos en la esencia de sus postulados para incorporar en el plano macroeconómico la economía del cuidado como una nueva dimensión en el análisis de la equidad en el contexto cubano de actualización del modelo económico.
