Year: 2021

description: En nuestros días, la interacción trabajo familia puede generar conflicto y afectar a la salud, el rendimiento, y el bienestar tanto individual como en el seno de las organizaciones empresariales. Según la literatura académica el trabajo influye en mayor medida en el ámbito familiar que al revés y por tanto la existencia de políticas de conciliación tiene una influencia positiva en el trabajador, aumentando su satisfacción, rendimiento laboral y mejorando su vida familiar. Este tema es además una cuestión de candente actualidad a nivel sociopolítico europeo ya que las medidas de conciliación han sido reconocidas en la UE como una herramienta importante para alcanzar objetivos políticos estratégicos como el crecimiento de tasas de empleo, la inclusión de los grupos vulnerables y la igualdad entre hombres y mujeres. En este artículo se analizan también algunas contribuciones destacadas como por ejemplo las realizadas por Hobson&Fahlén así el premio Nobel Amartya Sen.

description: Campylobacter jejuni is a Gram-negative bacterium and is the main cause of illnesses related to gastroenteritis in humans. As the outermost structure of Campylobacter jejuni, CPS were made into glycoconjugate vaccines to fight Campylobacter jejuni infection and and have shown promising results. Structural analysis of CPS related to C. jejuni serotype HS:4 revealed a repeating unit consisting of 4-substituted N-acetyl-β-D-glucopyranosamine and 3-substituted 6-deoxy-β-D-ido-heptopyranose. To this end, the focus of the thesis are synthetic studies on 6-deoxy-β-D-ido-heptopyranosides which could be attached to a carrier protein such as CRM197 for immunological studies. Two 6-deoxy-β-D-ido-heptopyranosides (115 and 116) have been successfully prepared for the first time. An efficient protocol to regioselectively convert one O-isopropylidene into di-O-acetates via acetolysis has been established for di-O-isopropylidene-protected D-galacto- and D-fructo-pyranosyl systems (Chapter 3). Trifluoroacetic acid (TFA) was found to achieve the regioselective acetolysis of a series of di-O-isopropylidene-protected hexopyranosides in acetic anhydride.

description: We use distance measurements in the nearby universe to carry out new tests of gravity, surpassing other astrophysical tests by over two orders of magnitude for chameleon theories. The three nearby distance indicators -- cepheids, tip of the red giant branch (TRGB) stars, and water masers -- operate in gravitational fields of widely different strengths. This enables tests of scalar-tensor gravity theories because they are screened from enhanced forces to different extents. Inferred distances from cepheids and TRGB stars are altered (in opposite directions) over a range of chameleon gravity theory parameters well below the sensitivity of cosmological probes. Using published data we have compared cepheid and TRGB distances in a sample of unscreened dwarf galaxies within 10 Mpc. As a control sample we use a comparable set of screened galaxies. We find no evidence for the order unity force enhancements expected in these theories. Using a two-parameter description of the models (the coupling strength and background field value) we obtain constraints on chameleon and symmetron screening scenarios. In particular we show that f(R) models with background field values fR0 above 5e-7 are ruled out at the 95% confidence level. We also compare TRGB and maser distances to the galaxy NGC 4258 as a second test for larger field values. While there are several approximations and caveats in our study, our analysis demonstrates the power of gravity tests in the local universe. We discuss the prospects for additional, improved tests with future observations.

Subjects: subject: Engineering--Mechanical
subject: Fracture Healing, Mechanoregulatory Algorithms, Stem Cells, Computational Analysis

description: Mechanical factors play a key role in regulation of tissue regeneration during skeletal healing, but the underlying mechanisms are not fully understood. The objective of the current study was to explore the role of mechanical factors on tissue differentiation during fracture healing, using a biphasic mechanoregulatory algorithm. The first specific objective was to investigate the effect of mechanical loading on a stem cell seeded collagenous scaffold in a one-dimensional confined compression configuration. Both empirical and computational data suggest that mechanical stimulation of the scaffold may be an effective way to initiate differentiation pathways prior to implantation for tissue engineering applications. The second objective was to predict the development of differentiated tissues in a tibia burr-hole fracture murine model with computational mechanoregulatory algorithms. The computational and experimental studies will be used simultaneously in future studies to further develop mechanoregulatory models with a more robust quantitative base.

description: We examine the dark energy and matter densities allowed by precision measurements of distances out to various redshifts, in the presence of spatial curvature and (near) arbitrary behavior of the dark energy equation of state. Degeneracies among the parameters permit a remarkably large variation in their values when using only distance measurements of the late time universe and making no assumptions about the dark energy or curvature. Going beyond distance measurements to a lower limit on the growth of structure bounds the allowed region significantly but still leaves considerable freedom to match a flat LCDM model with dark energy very different from a cosmological constant. The combination of distances with Hubble parameter, gravitational lensing or other large scale structure data is essential to determining robustly the cosmological model.

description: By combining first principles calculations and experimental XPS measurements, we investigate the electronic structure of potential Li-ion battery cathode materials LiMPO4 (M=Mn,Fe,Co,Ni) to uncover the underlying mechanisms that determine small hole polaron formation and migration. We show that small hole polaron formation depends on features in the electronic structure near the valence-band maximum and that, calculationally, these features depend on the methodology chosen for dealing with the correlated nature of the transition-metal d-derived states in these systems. Comparison with experiment reveals that a hybrid functional approach is superior to GGA+U in correctly reproducing the XPS spectra. Using this approach we find that LiNiPO4 cannot support small hole polarons, but that the other three compounds can. The migration barrier is determined mainly by the strong or weak bonding nature of the states at the top of the valence band, resulting in a substantially higher barrier for LiMnPO4 than for LiCoPO4 or LiFePO4.

Replication, stability, and incompatibility determinants of Rhizobium leguminosarum plasmids

description: The large stable plasmids of rhizobia play an important role in survival, environmental competition, and plant symbiosis. The six plasmids of Rhizobium leguminosarum bv. viciae VF39SM comprise nearly 35% of the bacterium’s genome and are all repABC replicons, which are defined by the presence of a highly unusual operon containing both replication (repC) and partitioning functions (repA and repB) under the control of a single promoter. The six repABC operons were isolated and were found to confer the autonomous replication, incompatibility characteristics, and strong stability of the large repABC plasmid from which they were derived. The repABC operons of the three largest plasmids were found to have strong incompatibility determinants in the non-protein coding regions, and the location and number of these determinants were unique to each operon. The varying incompatibility determinants were predicted to be the centromere-like site of the plasmid, based on the presence of a 16 nucleotide consensus palindromic sequence. However, in all three repABC operons, the intergenic region between repB and repC was the strongest incompatibility factor, and is predicted to encode a counter-transcribed RNA (ctRNA). Mutations in the promoter region of the ctRNAs result in loss of incompatibility. Deletion of the repA and repB genes of the repABC operons of the three largest plasmids abolished replicon stability, whereas deletion of the intergenic region increased the stability significantly, such that the intergenic deletion replicons were more stable than the entire repABC operon. Depending on the rhizobial host, the intergenic deletion replicon had increased stability due either to an increase in copy number (Agrobacterium tumefaciens host), or a cointegration event with the chromosome or a resident plasmid (A. tumefaciens or R. leguminosarum host). Genomic rearrangements are common in the rhizobial species in this study, but appear to be especially prevalent in R. leguminosarum VF39SM. Cointegration events to mitigate plasmid incompatibility or loss of plasmid stability are common and result in consistent and reproducible patterns, even in a RecA-deficient background.
Prevention and Management of Concussions in Youth Ice Hockey: Policy, Education, Beliefs and Behaviours

description: Sport-related concussions are a major health problem in youth sport and recreational activities. In youth ice hockey specifically, concussion is the most common injury resulting in medical attention or time loss from sport. Concerns surrounding the negative consequences associated with inappropriate management of concussion have resulted in a number of government and sporting organization recommendations for concussion education as a secondary injury prevention strategy. The rationale for this recommendation is that providing education will result in appropriate management following a suspected sport-related concussion (e.g., removal from play assessment by a qualified healthcare professional, full recovery, safe return to sport). Under this assumption, education can mitigate the potential long-term effects of an athlete continuing to play through the injury. This includes the potential prevention of prolonged recovery, long-term health consequences, and in rare cases death. There is evidence to suggest that concussion education may increase participant knowledge, but there is limited research regarding the effect of education on concussion-related beliefs and management behaviour. More research on the effectiveness of concussion prevention strategies is needed. In this dissertation, the burden of concussion across sports (including youth ice hockey) and primary and secondary concussion prevention strategies are described. A qualitative examination of the context of concussion management suggests barriers not typically addressed in conventional education programs can affect concussion management. Further, the association between receiving concussion education and concussion knowledge, beliefs and behaviours under the scope of a behaviour change theory are examined. Increases in knowledge among players, parents and coaches involved with youth ice hockey were found; but had little to no effect on concussion beliefs and concussion management behaviour. However, a national policy change in youth ice hockey delaying the age when body checking is introduced until age 13, resulted in a 64% reduction in the risk of concussion for 11-12 year old hockey players. Rule changes that modify evidence-informed risk factors for a specific sport are an effective means of concussion risk reduction. Further, research examining educational strategies targeting player, parent, and coach beliefs about concussion management and interventions that address barriers to management are needed.
Convective Instability Of The Solar Corona: Why The Solar Wind Blows

Publisher: name: arXiv
Year: 2012
Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)

description: Chapman's (1957) conductive model of the solar corona is characterized by a temperature varying as r**(-2/7) with heliocentric distance r. The density distribution in this non-isothermal hydrostatic model has a minimum value at 123 RS, and increases with r above that altitude. It is shown that this hydrostatic model becomes convectively unstable above r = 35 RS, where the temperature lapse rate becomes superadiabatic. Beyond this radial distance heat conduction fails to be efficient enough to keep the temperature gradient smaller than the adiabatic lapse rate. We report the results obtained by Lemaire (1968) who showed that an additional mechanism is then required to transport the energy flux away from the Sun into interplanetary space. He pointed out that this additional mechanism is advection: i.e. the stationary hydrodynamic expansion of the corona. In other words the corona is unable to stay in hydrostatic equilibrium. The hydrodynamic solar wind expansion is thus a physical consequence of the too steep (superadiabatic) temperature gradient beyond the peak of coronal temperature that can be determined from white light brightness distributions observed during solar eclipses. The thermodynamic argument for the existence of a continuous solar wind expansion which is presented here, complements Parker's classical argument based on boundary conditions imposed to the solutions of the hydrodynamic equations for the coronal expansion: i.e. the inability of the mechanical forces to hold the corona in hydrostatic equilibrium. The thermodynamic argument presented here is based on the energy transport equation. It relies on the temperature distribution which becomes super-adiabatic above a certain altitude in the inner corona.

description: Brain tumour initiating cells (BTICs) are stem-like cells hypothesized to mediate recurrence in high-grade gliomas. Preclinical success has been demonstrated in treating patient-derived BTICs with oncolytic virotherapy, using replication-competent viruses to target and kill malignant cells. Myxoma virus (MyxV) is an oncolytic candidate, which is highly effective in conventional glioma models, but only modestly effective in BTICs. The objective of this study was to improve MyxV efficacy in BTICs in vitro, combining chemotherapeutics and virotherapy. Using a pharmacoviral screen, eleven compounds that enhance MyxV-mediated cell death were identified. A lead compound, axitinib, was validated in multiple BTIC models. It was demonstrated that a virally encoded protein, M011L, prevents MyxV-induced apoptosis in BTICs, and M011L disruption was shown to greatly improve MyxV-mediated cell death through apoptosis induction. These studies have elucidated multiple strategies for improving MyxV efficacy in a preclinical glioma model, with implications for the future clinical development of MyxV.

description: We investigate experimentally a deterministic underdamped Josephson vortex ratchet -- a fluxon-particle moving along a Josephson junction in an asymmetric periodic potential. By applying a sinusoidal driving current one can compel the vortex to move in a certain direction, producing average dc voltage across the junction. Being in such a rectification regime we also load the ratchet, i.e., apply an additional dc bias current I_dc (counterforce) which tilts the potential so that the fluxon climbs uphill due to the ratchet effect. The value of the bias current at which the fluxon stops climbing up defines the strength of the ratchet effect and is determined experimentally. This allows us to estimate the loading capability of the ratchet, the output power and efficiency. For the quasi-static regime we present a simple model which delivers simple analytic expressions for the above mentioned figures of merit.

Year: 2010

description: The purpose of this study was to explore the meaning of retirement to adults with an intellectual disability in older age. Background: Seven adults between the ages of 50-60 years old participated in in-depth semi-structured interviews on the subject of retirement. All participants lived independently in the community, three participants were male and four participants were female. Method: An interview guide was used to address topics related to retirement. Interviews were approximately one hour in duration. Data was analyzed to find content themes. Findings: Three key themes came out of the data; the economics of retirement, desire for choices in retirement, and changing relationships with ageing parents. Discussion: Rethinking the term “retirement” in order to be more inclusive to the experience of populations who may not have participated in the paid workforce, acknowledgement of the transition from a “person with a disability” to a “senior citizen”, and education in regards to retirement and the issues that arise at this time of life are areas of discussion that came forward in this study.

description: Sedimentary rocks within the Fernie Formation of the Western Canadian Sedimentary Basin (WCSB) accumulated upon the western epicratonic margin of North America. Along this margin the depositional environments ranged from open marine to continental in origin. In west-central Alberta the deposits of this formation were initially mixed siliciclastic-carbonate sediments that upwardly were replaced by siliciclastic deposits during the Jurassic. Dissection of these deposits through high resolution analyses of lithofacies, lithofacies associations, and lithosomes reveals three main coastal depositional systems for Toarcian through Kimmeridgian strata of the formation: a storm- and wave-reworked lower Rock Creek Member (Aalenian), a tidally-reworked upper Rock Creek Member (Bajocian) unit dissected by tidal channels, and an enigmatic Oxfordian interval herein named the Niton Member that represents a progradational shallow-marine strand plain subsequently decapitated by a marine incursion. These three depositional systems are separated by widespread unconformable surfaces.

description: Fluid and solute transfer in X-junctions between straight channels is shown to depend critically on the junction angle in the Stokes flow regime. Experimentally, water and a water-dye solution are injected at equal flow rates in two facing channels of the junction: Planar Laser Induced fluorescence (PLIF) measurements show that the largest part of each injected fluid "bounces back" preferentially into the outlet channel at the lowest angle to the injection; this is opposite to the inertial case and requires a high curvature of the corresponding streamlines. The proportion of this fluid in the other channel decreases from 50% at 90\degree to zero at a threshold angle. These counterintuitive features reflect the minimization of energy dissipation for Stokes flows. Finite elements numerical simulations of a 2D Stokes flow of equivalent geometry con rm these results and show that, below the threshold angle 33.8\degree recirculation cells are present in the center part of the junction and separate the two injected flows of the two solutions. Reducing further leads to the appearance of new recirculation cells with lower flow velocities.

description: Traumatic neuroma-in-continuity (NIC) injuries result in profound neurological deficits, and its management poses the most challenging problem to peripheral nerve surgeons. The absence of a clinically relevant experimental model continues to handicap our ability to investigate ways of better diagnosis and treatment for these disabling injuries. The aim of this project was to develop and refine a clinically relevant small animal NIC injury model to allow us to better understand this injury and the anatomical substrates for the associated poor functional recovery. An intense focused compression force in combination with a small traction force produced histological features and functional deficits consistent with NIC injuries in rat nerves. The methods were refined to identify a small NIC force window that is to be targeted to reproduce these injuries. With these methods the detrimental role of axonal attrition and misdirection on functional recovery was confirmed to characterize and validate this new model.

Based on the matrix model, we derive the baryon interaction at short distances in multi-flavor holographic QCD. We show that there is a very universal repulsive core of inter-baryon forces for generic number of flavors. This is consistent with a recent lattice QCD analysis for N_f = 2, 3 where repulsive core looks universal. We also provide a comparison of our results with the lattice QCD and the operator product expansion (OPE) analysis.

Possibilities and limitations of digital multitasking for school homework

Year: 2021

description: The digitisation of the classroom and the increased use of information and communications technologies (ICTs) at home offer ways to improve students’ educational performance. Yet misuse of the Internet and increased digital multitasking at home, where academic study and entertainment intersect, could create barriers towards academic achievement. Based on the concept of “Cognitive Load Theory” and taking a qualitative approach rooted in Critical Communicative Methodology (CCM), this study aims to examine this topic in more depth. After interviewing four focus groups consisting of 40 students from 5th and 6th grade Elementary and 1st and 2nd Grade ESO (“Educación Secundaria Obligatoria”/Compulsory Secondary Education), results revealed that students are accustomed to using computers in environments where digital study and digital entertainment are both available. Students see learning possibilities on the screen in front of them, but are also aware of the distractions in this kind of mixed, instantly available environment. This study suggests that multitasking skills should be taught formally in order to avoid students pursuing a syncopated mix of online work and social media use. Faced with this reality of how students work, the study proposes that instead of teachers focusing exclusively on formal instruction, they should offer a measured/controlled approach to multitasking activities within a reflexive, hyperlinked environment. This is the first tentative conclusion from what will be a wider, more detailed investigation involving teachers, administrators and families all within the same school in Barcelona.

description: We present an experimental analysis of force noise caused by stray electrostatic fields acting on a charged test mass inside a conducting enclosure, a key problem for precise gravitational experiments. Measurement of the average field that couples to test mass charge, and its fluctuations, is performed with two independent torsion pendulum techniques, including direct measurement of the forces caused by a change in electrostatic charge. We analyze the problem with an improved electrostatic model that, coupled with the experimental data, also indicates how to correctly measure and null the stray field that interacts with test mass charge. Our measurements allow a conservative upper limit on acceleration noise, of 2 fm/s$^2$\rthz\ for frequencies above 0.1 mHz, for the interaction between stray fields and charge in the LISA gravitational wave mission.

description: Bibliography: p. 164-176
description: Literacy studies in recent decades have focused on the home environment as the place where a child's language and literacy development takes roots. Literacy is viewed as situated practices framed by sociocultural factors. While the study of English-speaking families had drawn much attention originally, recent years have seen the call for studying the home literacy environment of families from diverse cultural and linguistic backgrounds, in light of our ever-increasing multicultural population. Using an in-depth, ethnographic method, the present study focuses on three immigrant families from Hong Kong. The interplay of parental views, the home literacy environment and the language learning of the Canadian-born child is explored. Findings reveal significant themes such as parental expectations, home literacy milieu, bilingual development as well as identity constructs of the second generation in these immigrant homes. Implications are drawn for the school and policy making, and future research directions are discussed.

description: Using a well-established effective interaction in a rainbow-ladder truncation model of QCD, we fix the remaining model parameter to the bottomonium ground-state spectrum in a covariant Bethe-Salpeter equation approach and find surprisingly good agreement with the available experimental data including the 2^{--} Upsilon(1D) state. Furthermore, we investigate the consequences of such a fit for charmonium and light-quark ground states.

description: El denominado estado del bienestar constituye sin duda el gran logro social del siglo XX en buena parte del mundo. Aunque con diferencias entre países, se asienta sobre cuatro pilares fundamentales: educación, salud, pensiones y otros servicios sociales (entre los que se incluye la atención a las personas en situación de dependencia). En la actualidad, se enfrenta a un gran reto que sin duda condicionarán su evolución futura: el envejecimiento de la población. Ello es debido, por una parte, a que el grueso de los programas de gasto social es muy dependiente de la estructura de edades de la población (pensiones, sanidad, atención a la dependencia). Por otra parte, el conjunto de programas de gasto público social se organizan implícitamente mediante un sistema de reparto (las prestaciones se financian con la recaudación del mismo momento temporal). De manera que, a lo largo del proceso de envejecimiento demográfico, una proporción decreciente de personas en edad activa se verá obligada a afrontar un creciente gasto social con el pago de impuestos. Sin embargo, muy a menudo se obvia que el envejecimiento no es un reto únicamente para los programas públicos: reducir las transferencias públicas no resuelve en absoluto el problema, sino que únicamente lo traslada al ámbito privado de los individuos y sus familias, como muestran los resultados de las cuentas de transferencias nacionales presentados en este trabajo. Así pues, las sociedades deben prepararse para repensar de manera integral la distribución de los recursos económicos a lo largo del ciclo vital de las personas.

Treacherous Ties: a Comparative Look at Betrayal in the Norse Myths of the Völsungs and Euripides' House of Atreus Plays

subject: Euripides
subject: Edda

description: The Norse myths featuring the Völsung family and the Greek plays of Euripides are multigenerational mythic arcs containing many acts of betrayals. Yet there are key differences in the way betrayal features in each of the sets of stories studied. Through these differences, it is possible to determine the level of import given to specific family relationships in each of the mythic cycles’ two cultures. Some important differences occur in the way women are perceived in each culture and the level of importance given to close kin versus the society at large. In both mythic cycles, however, betrayal is subject to public scrutiny. The opinion of the cultural group is what decides on the consequences enacted on the betrayer for an act of betrayal. The concept of betrayal, despite being a conservative force, is revealed to be a social mechanism that can over time enact change on the values held by a cultural group.
Neuromodulation and Synaptic Plasticity in the Dorsomedial Hypothalamus

description: The dorsomedial nucleus of the hypothalamus (DMH) is a key player in the maintenance of a number of vital homeostatic functions including the regulation of food intake. Despite this important role, surprisingly little is known about synaptic processing and plasticity of synapses in this nucleus. The main objective of this thesis was to investigate how inhibitory GABAergic synapses in the DMH are modulated in response to satiety and stress signals. Specifically, using an electrophysiological approach, we examined the impact of the satiety peptide, cholecystokinin, and stress triggered by food deprivation on the signaling and plasticity of GABA synapses in the DMH. Whole cell electrophysiological recordings were obtained from DMH neurons using male Sprague-Dawley rats, postnatal day (P) 21-30. The work presented here demonstrates that CCK potentiates GABAergic synaptic inhibition through two novel mechanisms. First, following dendritic release from DMH neurons, CCK acts in an autocrine fashion to inhibit these neurons through a CCK1 receptor-mediated pathway that requires retrograde NO signaling and potentiation of GABA release from the presynaptic terminal. Second, in response to bursts of afferent activity resulting in surges of glutamate release, CCK triggers long term potentiation of GABA synapses mediated by CCK2 and group I metabotropic receptors putatively localized on neighboring astrocytes. Activation of these receptors stimulates release of ATP which subsequently acts at GABA terminals to increase the probability of GABA release. The present findings also demonstrate that the feeding state of an animal shifts the plasticity of GABA synapses from endocannabinoid-mediated long term depression observed in satiated animals to nitric oxide-mediated long term potentiation. This is due to a stress-induced down-regulation of cannabinoid receptors in food-deprived animals. Overall, the work in this thesis has significantly enhanced our understanding of neuromodulation and synaptic plasticity in the DMH.
The dragon with the blue beret : China's contributions to United Nations peacekeeping operations

description: Recently, academics and policy analysts alike have taken note of the People’s Republic of China’s increasing participation in United Nations peacekeeping operations (UNPKO). Since 2003, the overall number of Chinese personnel in UNPKO has climbed dramatically: from 120 in early 2003 to over 2,000 at present. However, while it is relatively easy to determine how many Chinese personnel serve in UNPKO, it is much more difficult to accurately determine China’s motives for participation in the UN peacekeeping regime and its mission selection criteria. At present, there are three main schools of thought on this subject. Chinese officials and academics tend to argue that the PRC contributes to UNPKO because it is genuinely concerned about promoting international peace and security and alleviating human suffering. Other authors, primarily from the United States, argue that the PRC’s motives are purely instrumental in nature. China, they contend, sends personnel to missions when doing so can increase the PRC’s access to natural resources and markets or augment its overall diplomatic and military power. Finally, some authors vaguely contend that China’s concerns over its international legitimacy play a role in its peacekeeping strategy. This thesis advances a new version of the international legitimacy explanation of Chinese peacekeeping participation. Specifically, it uses case studies from China’s past and current participation in UNPKO to demonstrate how reputational concerns have and continue to be the primary determinants of China’s peacekeeping policy. It argues that China participates in UNPKO to improve its international image in two important ways. First, China wants to show other great powers that it supports the status quo international system, thereby undermining claims that it is a dangerous “revisionist power.” Second, the PRC wants to ameliorate concerns among the international community that it is behaving in an exploitative way toward the developing world.
Photometric and Spectroscopic Signatures of Superluminous Supernova Events The puzzling case of ASASSN-15lh

description: Superluminous supernovae are explosions in the sky that far exceed the luminosity of standard supernova events. Their discovery shattered our understanding of stellar evolution and death. Particularly, the discovery of ASASSN-15lh a monstrous event that pushed some of the astrophysical models to the limit and discarded others. In this thesis, I recount the photometric and spectroscopic signatures of superluminous supernovae, while discussing the limitations and advantages of the models brought forward to explain them. I show that a quark nova occurring in the wake of a supernova remnant of an Oxygen-type Wolf-Rayet star can reproduce the light curve, photospheric radius and effective temperature evolution of ASASSN-15lh. This model was used to successfully simulate the spectrum of the event using SYNOW. Beyond being a successful explanation for ASASSN-15lh, the quark nova model is an appealing mechanism to power the most luminous events ever seen in the sky.

description: Uno de los mayores retos al que se enfrentan los sistemas sanitarios de los países desarrollados es la atención a las personas afectadas por enfermedades crónicas, cuya creciente prevalencia es, en parte, consecuencia del envejecimiento de la población. En este contexto, las personas deberían acceder y comprender la información necesaria para participar activamente en la gestión de la propia salud y en la toma de decisiones que les afectan en el día a día. Este artículo presenta los resultados principales de un estudio realizado sobre el comportamiento del paciente crónico y de sus necesidades de atención sanitaria en el contexto español. El trabajo de campo realizado se basó en la metodología de recogida de datos de tipo cualitativo, con el objetivo de conocer las necesidades del paciente crónico en relación a la atención sanitaria. Se realizaron 10 entrevistas semiestructuradas a expertos y dos grupos focales con la participación total de 14 personas que padecían enfermedades crónicas. El análisis de contenido mediante comparación continua mostró que los pacientes tienen dificultades para orientarse en los centros hospitalarios, que la información por sí sola no es eficaz para generar un buen autocuidado y que la información recibida, a menudo, contiene un lenguaje técnico muy complejo y poco centrado en el paciente, entre otros resultados. Es necesario, pues, promover la investigación y la formación en competencias de autocuidado tanto en pacientes como en profesionales; así como planificar y desarrollar actuaciones a nivel de las políticas sanitarias que sirvan para mejorar la situación del paciente crónico.
