Filosofía de la liberación
Authors: Neira Hernán 
Published: August 2024

Ha muerto Enrique Dussel. La persona, no su filosofía. Enrique Dussel es uno de los filósofos latinoamericanos de mayor influencia en el mundo. No es extraño que uno de los filósofos más “latinoamericanos” (este adjetivo es utilizado como desprecio u orgullo, según quién lo pronuncie) sea, a la vez, uno de los más cosmopolitas, por la amplitud de sus fuentes intelectuales y su repercusión en públicos no latinoamericanos. A diferencia de quienes colocan en Grecia el origen de la filosofía y, en especial, de la filosofía política, él la colocó en las fuentes de la filosofía griega: el mundo semita, el de los herederos del personaje bíblico Sem, lo que incluye mucho del mundo cultural que hoy son los países árabes de Oriente Medio, Israel y del norte de África. Asimismo, Dussel, como otros autores, han planteado que la filosofía no surge de un único milagro, griego, sino de muchos milagros, dispersos cultural y geográficamente, lo que justifica la existencia de filosofías auténticas a partir de distintas fuentes. Asimismo, también declaró inspirarse en el pensamiento amerindio.
La Odisea de Kazantzakis como obra cretense y modernista
Authors: González Vaquerizo Helena , Fredericksen Neira Alfredo 
Published: August 2024

La Odisea de Nikos Kazantzakis se publicó por primera vez en 1938 y desde entonces se ha considerado principalmente como un largo poema pasado de moda. Al mismo tiempo, sus últimas novelas se han vinculado con precisión a la ficción modernista y se han establecido conexiones entre la poesía épica y el modernismo. Este artículo asume que los argumentos presentados por los académicos que se ocupan de estos temas también pueden aplicarse a la nueva Odisea. Así, este trabajo profundiza en algunas de las estrategias modernistas que el autor adopta en este poema: principalmente el uso de la ficción y el método mítico, y la asimilación y manipulación de elementos cretenses —en su mayoría— minoicos. Este enfoque no solo revela más paralelos entre la Odisea de Kazantzakis y el Modernismo europeo de lo que se suponía anteriormente, sino que también proporciona una explicación para el desarrollo de tales elementos en las novelas posteriores.
Nietzsche y el tiempo de la amistad
Authors: Oyarzún Luis Felipe 
Published: August 2024

En este trabajo busco dar cuenta de la dimensión temporal que Nietzsche observa en la constitución de la vida misma. No se trata tan sólo de la vida como devenir de un continuo de puntos que vienen unos tras otros hacia un infinito lineal sino de algo más. Para ello recorro pasajes particularmente de La ciencia jovial y de Así habló Zaratustra, desarrollando los conceptos de eternidad, amistad, abismo de luz y viajero, en el contexto de la muerte de Dios. Una vez que la vida sólo puede ser contemplada y vivida sin referencias a instancias externas a ella misma, emerge en el corazón de la experiencia humana su estructura temporal propia, encontrando con ello un vínculo entrañable entre vida, tiempo y (voluntad de) poder.

Realismo y apriorismo en la epistemología platonista de Jerrold Katz
Authors: Guirado Matías 
Published: August 2024

En Realistic Rationalism (1998), Jerrold Katz hizo extensiva su postura en filosofía del lenguaje y lingüística al campo de las ciencias formales tradicionales. El proyecto del libro es mostrar que la lógica y la matemática proporcionan conocimiento sintético a priori de verdades necesarias. El desarrollo de este proyecto epistemológico aparece estrechamente vinculado a la promoción de un componente metafísico-modal, que declara que las ciencias formales estudian propiedades y relaciones inmutables instanciadas por objetos abstractos (i.e., no-espaciales y atemporales) necesariamente existentes. En efecto: este componente juega un papel destacado en la dilucidación de las condiciones de posibilidad de la síntesis a priori y, por añadidura, en la explicación de la certeza objetiva de las verdades lógicas y matemáticas. En este trabajo sostengo que el proyecto epistemológico de Katz es inviable, por tres motivos: primero, la postulación de entidades modalmente necesarias no es una condición sine qua non para explicar el tipo particular de certeza que caracteriza a las ciencias formales; segundo, es perfectamente factible dar una explicación anti-realista del carácter a priori del conocimiento de verdades formales; tercero, los argumentos de Katz en favor de la existencia necesaria de objetos abstractos son falaces.

A asma é uma doença crônica com alta prevalência na infância, caracterizada pela inflamação das vias aéreas, resultando no comprometimento da qualidade de vida das crianças acometidas.Nesse contexto, diversos agentes farmacológicos, como corticosteróides inalados, broncodilatadores e novos agentes terapêuticos, emergem como possíveis terapias farmacológicas a fim de otimizar o manejo da doença e melhorar a qualidade de vida das crianças afetadas, tornando-se necessário a realização de estudos para análise da eficácia e direcionamento efetivo da prática clínica, contribuindo para uma abordagem mais promissora para o manejo da asma infantil. Desse modo, este estudo teve como objetivo comparar o uso de corticosteroides inalados, broncodilatadores e novos agentes terapêuticos. A metodologia empregada no estudo foi a de uma revisão integrativa da literatura, com busca em bases de dados relevantes, resultando na seleção de 15 estudos que atendiam aos critérios de inclusão. Os resultados indicam que, embora os corticosteroides sejam eficazes, outros agentes terapêuticos podem oferecer benefícios significativos, especialmente em termos de adesão ao tratamento e controle de sintomas, sem os efeitos adversos associados ao uso prolongado de corticosteroides, enfatizando a importância de uma abordagem individualizada no tratamento da asma, considerando as preferências dos pacientes e cuidadores. Portanto, evidenciou-se a necessidade de pesquisa contínua para estabelecer diretrizes claras sobre a combinação de terapias, visando garantir que as crianças asmáticas recebam o tratamento mais eficaz e seguro, melhorando assim sua qualidade de vida.

Published: August 2024

Animal-assisted therapy in children with autism (AAT) is a complementary therapy, which includes procedures from all other therapies. AAT is a group of interventions based on an animal's behavioural characteristics (the most common therapy animals being dogs), which, depending on needs, can be included in standard treatments such as behavioural therapy, play therapy, music therapy, occupational therapy, speech therapy and art therapy. The purpose of this study was to evaluate the impact of an existing TAA program on social communication skills, executive functions, and motor skills in children diagnosed with ASD. The study used an observational research design, exploring the frequency of behaviors when dogs are present or absent from an intervention group program. This study involved 16 children, diagnosed with ASD, aged between 7 and 13 years (12 boys and 4 girls) who were recruited from the School Center for Inclusive Education (C.S.E.I.) "LACRIMA" BISTRIȚA. The results obtained by us concluded that Canide-Assisted Therapy, applied under the conditions of our experiment, led to a significant improvement in all behavioral parameters taken in the study. We notice the positive effect, especially on the parameters related to group gaming behavior with a share of 38.7% higher than the control group, Eye Contact with a share of (15.68%) higher than the control group and Social Attention with a share of 28.57% higher than the control group. We also notice a positive effect on the parameters regarding emotional and physical functionality.
Oxygen isotope thermometry, speedometry, and hygrometry: Apparent equilibrium temperature versus closure temperature
Authors: Ni Huaiwei 
Published: December 2014

AbstractRather than indicating formation/peak temperature, oxygen isotope fractionations preserved in mineral assemblages of slowly cooled plutonic and metamorphic rocks yield apparent equilibrium temperatures (Tae). The isotopic fractionations and Tae values deliver information about cooling history, as the extent of diffusive exchange of oxygen isotopes during cooling is controlled by the cooling time scale or cooling rate. Despite that several models, such as the Fast Grain Boundary (FGB) model, have been developed to simulate oxygen isotope exchange between coexisting minerals during cooling, extraction of cooling rate remains far from straightforward. On the other hand, there is a well‐defined quantitative relationship between the Dodson closure temperature (Tc) and the cooling rate, but Tc cannot be directly measured. Based on simulation results of existing models for a variety of rock systems, including open systems (with an infinite fluid reservoir), closed systems (with negligible fluid participation) and semi‐open systems (with moderate fluid participation), this study demonstrates that Tae of the mineral pair with the largest equilibrium isotope fractionation (PLEIF) is always bounded by their Tc values, regardless of how mineral proportions vary or how significant a role fluid has played in isotopic exchange. If the two Tc values happen to be similar, Tae will serve as a good approximation of both Tc, provided that the equilibrium fractionation factor has been precisely determined as a function of temperature. One such pair is quartz‐magnetite. By contrast, a mineral pair with similar Tc but relatively small fractionation is susceptible to the disturbance from other minerals, hence does not always have Tae confined within their Tc range. The relationship of Tae‐Tc correspondence for PLEIF with similar Tc can be used to constrain either cooling rate (i.e., as a speedometry method) or oxygen isotope diffusivity if one of them has been independently determined. In the latter case, the inferred oxygen diffusivity may be an index of water fugacity (i.e., as a hygrometry method) when compared with experimental diffusivity values measured under different fluid conditions.
Preferential amplification of rising versus falling frequency whistler mode signals

Published: December 2014

AbstractAnalysis of ground‐based ELF/VLF observations of injected whistler mode waves from the 1986 Siple Station experiment demonstrates the preferential magnetospheric amplification of rising over descending frequency‐time ramps. From examining conjugate region receptions of ±1 kHz/s frequency‐time ramps, we find that rising ramps generate an average total power 1.9 times higher than that of falling frequency ramps when both are observed during a transmission. And in 17% of receptions, only rising ramps are observed above the noise floor. Furthermore, the amplification ratio inversely correlates with the noise and total signal power. Using a narrowband Vlasov‐Maxwell numerical simulation, we explore the preferential amplification due to differences in linear growth rate as a function of frequency, relative to the frequency which maximizes the linear growth rate for a given anisotropy, and in nonlinear phase trapping. These results contribute to the understanding of magnetospheric wave amplification and the preference for structured rising elements in chorus.
Uncovering local magnetospheric processes governing the morphology and variability of Ganymede's aurora using three‐dimensional multifluid simulations of Ganymede's magnetosphere

Published: December 2014

AbstractWe investigate local magnetospheric processes governing the morphology and variability of Ganymede's aurora depending on its position with respect to the center of the Jovian plasma sheet. We couple an existing three‐dimensional multifluid simulation to a new aurora brightness model developed for this study. With this, we are able to qualitatively and quantitatively show that the short‐ and long‐period variabilities observed in Ganymede's auroral footprint at Jupiter are also predicted to be present in the brightness and morphology of the aurora at Ganymede. We also examine the relationship between acceleration structures and precipitation of electrons in Ganymede's neutral atmosphere by looking at the component of the electric field parallel to Ganymede's magnetic field. Our results confirm that regions of electron accelerations coincide with regions of brightest auroral emissions, as expected. Finally, we identify the likely source regions of electrons generating the aurora at Ganymede and discuss the plasma dynamic mechanisms likely responsible for these accelerations.
Upstream proton cyclotron waves at Venus near solar maximum

Published: December 2014

AbstractLong‐term magnetometer data of Venus Express are analyzed for the occurrence of waves at the proton cyclotron frequency in the spacecraft frame in the upstream region of Venus, for conditions of rising solar activity. The data of two Venus years up to the time of highest sunspot number so far (1 Mar 2011 to 31 May 2012) are studied to reveal the properties of the waves and the interplanetary magnetic field (IMF) conditions under which they are observed. In general, waves generated by newborn protons from exospheric hydrogen are observed under quasi‐ (anti)parallel conditions of the IMF and the solar wind velocity, as is expected from theoretical models. The present study near solar maximum finds significantly more waves than a previous study for solar minimum, with an asymmetry in the wave occurrence, i.e., mainly under antiparallel conditions. The plasma data from the Analyzer of Space Plasmas and Energetic Atoms instrument aboard Venus Express enable analysis of the background solar wind conditions. The prevalence of waves for IMF in direction toward the Sun is related to the stronger southward tilt of the heliospheric current sheet for the rising phase of Solar Cycle 24, i.e., the “bashful ballerina” is responsible for asymmetric background solar wind conditions. The increase of the number of wave occurrences may be explained by a significant increase in the relative density of planetary protons with respect to the solar wind background. An exceptionally low solar wind proton density is observed during the rising phase of Solar Cycle 24. At the same time, higher EUV increases the ionization in the Venus exosphere, resulting in higher supply of energy from a higher number of newborn protons to the wave. We conclude that in addition to quasi‐ (anti)parallel conditions of the IMF and the solar wind velocity direction, the higher relative density of Venus exospheric protons with respect to the background solar wind proton density is the key parameter for the higher number of observable proton cyclotron waves near solar maximum.
Resonant seismic and microseismic ground motion of the Cascadia subduction zone accretionary prism and implications for seismic velocity
Authors: Davis Earl E. , Heesemann Martin 
Published: December 2014

AbstractSeafloor pressure and seismic observations have been made along a transect of sites off southwestern Canada using connections to the NEPTUNE Canada cabled network beginning in the fall of 2009. A comparison of the vertical ground motion response to oceanographic and seismic loading at a site on the outer Cascadia subduction zone accretionary prism to that at a site on the adjacent Juan de Fuca Plate shows generally stronger ground motion at the prism site across the full bandwidths of infragravity waves and microseisms and a strong sharp peak in the relative response at a period of 9 s. This peak is seen in the response to loading by local storm waves and dispersive swell sequences, as well as in the average response to storm‐ and swell‐generated pressure fluctuations averaged over long periods of time. Tuned response to teleseismic surface waves is also seen at the same frequency. We infer that this behavior results from quarter‐wavelength harmonic resonance of the prism, with the two‐way travel time of compressional waves between the seafloor and underlying igneous crust being one half the resonance period. The consistency of the anomalous spectral peak from year to year at this particular site suggests that the behavior might be used to track small (≈1%) changes in the vertical seismic velocity of the prism if variations related to strain or pore fluid pressure changes through a subduction thrust earthquake cycle were to occur.
Do Brand Advertising Spillovers Matter?
Authors: Li Xun , Lopez Rigoberto A. 
Published: December 2014

ABSTRACTThis article examines the spillover effects of television brand advertising on consumer demand, using carbonated soft drinks as a case study. Spillover effects are modeled using the conventional linear and constant elasticity of substitution (CES) advertising production functions. The latter allows for imperfect substitution between brand advertising and spillovers from advertising all other brands belonging to the same company as well as relaxes the assumption of constant returns to scale. Empirical results confirm strong and positive brand advertising spillover effects across brands belonging to the same company as well as negative spillover effects from advertising by competitors. Empirical results also indicate that the CES advertising production function outperforms the linear function, providing strong support for decreasing returns to scale in advertising and imperfect substitution between brand advertising and advertising of other brands in the same company. Finally, the CES function results in significantly higher estimates of the price elasticities of demand as well as lower estimated markups. [EconLit citations L13, L66, M37].
Accrual Anomaly for Agribusiness Stocks
Authors: Arthur Bruno R. , Katchova Ani L. 
Published: December 2014

ABSTRACTThis study investigates whether the accrual anomaly documented by Sloan () for the U.S. market stocks exists in the U.S. agribusiness stocks over 1971–2011. Our results for the U.S. agribusiness stocks concur with the results of Trejo‐Pech, Weldon, House, and Gunderson () for the food supply chain stocks that the anomaly is explained by the high accrual portfolios rather than the fixation hypothesis. The accrual anomaly remains for agribusiness stocks even after accounting for the momentum factor with the four‐factor asset pricing model, and is more driven by the non‐food supply chain stocks than the food supply chain stocks. Our results from Fama and MacBeth () regressions confirm that accruals are negatively related to future returns.

Published: December 2014

BackgroundOsteitis, characterized by bony thickening and remodeling, is often considered a hallmark of recalcitrant rhinosinusitis. However, there is limited literature examining the bone in chronic rhinosinusitis (CRS) pathology. In this study we cultured osteoblasts from bone harvested during sinus surgery as well as from nondiseased controls to compare their cellular properties.MethodsSinus bone was collected during sinus and skull‐base surgery and placed in proliferation media. Outgrowth of cells occurred at 2 weeks and the cells were confirmed to be osteoblasts by alkaline phosphatase staining. Cellular adhesion was determined by replating and counting adhered cells at 4 hours. Proliferation of cells plated for 24 hours was assayed by measuring [3H]‐thymidine incorporation. Calcium content was measured by changing cells to differentiation media and measuring the calcium content on days 7, 14, and 21.ResultsAlkaline phosphatase assay showed more than 90% of osteoblasts staining in all samples. Osteoblasts from patients with CRS had significant decreases in adhesion (p < 0.01) compared to osteoblasts from skull‐base patients. There was a significant (p < 0.05) increase in calcium content in rhinosinusitis samples compared with the nondiseased sinus bone samples.ConclusionTo date, this is the first known study that shows a direct comparison of osteoblast properties between patients with and without CRS. Our results indicate that there are fundamental phenotypic differences in adhesion and mineralization between osteoblasts in patients with CRS compared to controls.
Covariate‐adjusted measures of discrimination for survival data
Authors: White Ian R. , Rapsomaniki Eleni ,   for the Emerging Risk Factors Collaboration
Published: December 2014

MotivationDiscrimination statistics describe the ability of a survival model to assign higher risks to individuals who experience earlier events: examples are Harrell's C‐index and Royston and Sauerbrei's D, which we call the D‐index. Prognostic covariates whose distributions are controlled by the study design (e.g. age and sex) influence discrimination and can make it difficult to compare model discrimination between studies. Although covariate adjustment is a standard procedure for quantifying disease‐risk factor associations, there are no covariate adjustment methods for discrimination statistics in censored survival data.ObjectiveTo develop extensions of the C‐index and D‐index that describe the prognostic ability of a model adjusted for one or more covariate(s).MethodWe define a covariate‐adjusted C‐index and D‐index for censored survival data, propose several estimators, and investigate their performance in simulation studies and in data from a large individual participant data meta‐analysis, the Emerging Risk Factors Collaboration.ResultsThe proposed methods perform well in simulations. In the Emerging Risk Factors Collaboration data, the age‐adjusted C‐index and D‐index were substantially smaller than unadjusted values. The study‐specific standard deviation of baseline age was strongly associated with the unadjusted C‐index and D‐index but not significantly associated with the age‐adjusted indices.ConclusionsThe proposed estimators improve meta‐analysis comparisons, are easy to implement and give a more meaningful clinical interpretation.
