Consideraciones y críticas del positivismo
Authors: Pérez Rodas Walter Arturo
Published: September 2020

Reacciones propias a la lectura de Alberto Fernández, “El primer positivismo: algunas consideraciones sobre el pensamiento social de Saint Simón y Comte” y de Gustavo Paredes, “Críticas epistemológicas y metodológicas a la concepción positivista en ciencias sociales”. Desde el inicio de las lecturas las críticas de Fernández y Paredes fueron claras y sobre todo alteraron las percepciones de un médico con orientación occidental, con formación en método científico, hábil y amante de los números y fuerte defensor de lo medible. Henry de Saint-Simon presentó la crisis como la existencia de incompatibilidades y como estas han continuado hasta una sociedad actual dirigida eminentemente por la industria; además como el positivismo y sus cuatro ideas fundamentales, expuestas por Auguste Comte, siguen teniendo mucha validez. No cabe duda que actualmente se debe ver, pensar, imaginar y actuar más allá del positivismo.

Published: September 2020

Introducción: La Unidad de Manejo Forestal 0807 (UMAFOR 0807) es una de las más productivas en madera y provisión de recursos hídricos, pero no existen estudios de la variabilidad hidroclimática histórica y de sus tendencias para fines predictivos.Objetivo: Generar una reconstrucción de precipitación mediante una red dendrocronológica regional para el suroeste del estado de Chihuahua.Materiales y métodos: Una red de series de crecimiento de cinco coníferas distintivas de la UMAFOR 0807 se desarrolló; mediante componentes principales se definieron las series con mayor varianza común para la obtención de una representativa. El modelo de reconstrucción se generó con una serie de precipitación regional. Se analizaron los modos de circulación general con mayor impacto en la variabilidad de lluvia y la asociación del índice de anillo total con los índices de sequía.Resultados y discusión: De ocho cronologías generadas, seis mostraron una respuesta climática común para integrar una serie representativa regional, la cual respondió a la precipitación septiembre-julio. La correlación entre el índice de anillo total e Índice de Severidad de Sequía de Palmer (PDSI) fue 0.68 (P < 0.01) en el periodo junio-agosto, y 0.71 (P < 0.01) para el Índice Estandarizado de Precipitación Evaporación (SPEI) de agosto del año previo a junio del año actual de crecimiento. La precipitación reconstruida mostró significancia en picos espectrales de 2.1 y 2.8 años, que corresponden a la influencia de ENSO (El Niño Oscilación del Sur).Conclusiones: La red dendrocronológica compuesta por diversas especies arbóreas e integrada en una cronología regional permitió captar la variabilidad interanual y multianual del clima.

Introducción: El cedro rojo (Cedrela odorata L.) es apreciado por su madera, situación que ha ocasionado un mal manejo forestal y, por ende, la disminución de sus áreas de distribución.Objetivo: Delimitar la distribución potencial actual y futura de C. odorata e identificar áreas idóneas productoras de semillas para la conservación de la especie en la península de Yucatán.Materiales y métodos: Se obtuvieron registros de presencia de C. odorata de la plataforma Global Biodiversity Information Facility (GBIF), del Inventario Nacional Forestal y de Suelos (INFyS) y del libro “Árboles tropicales de México”. La modelación se realizó en MaxEnt utilizando variables ambientales actuales y de escenarios futuros (2030) de cambio climático a 1 km2 de resolución espacial. Se empleó 75 % de los registros para entrenar los modelos y 25 % para validarlos. Las variables con mayor contribución se determinaron mediante la prueba jackknife.Resultados y discusión: La distribución potencial actual estimada de C. odorata fue 404917 ha. Las simulaciones de cambio climático predicen reducción (31 a 44.8 %) del hábitat idóneo, donde las áreas naturales protegidas (ANP) de Calakmul, Los Petenes y Ría Celestún fungirían como refugios climáticos, conservando cerca de 76472 ha. Las variables importantes en la distribución fueron: vegetación (34.7 %), precipitación del mes más húmedo (14.6 %), edafología (8.8 %), temperatura media del trimestre más frío (8.6 %) y pendiente (7 %).Conclusión: Los modelos permitieron la identificación de áreas idóneas con calidad de hábitat de C. odorata. Ante las amenazas del cambio climático, la distribución de C. odorata en las ANP ayudaría a los programas de conservación y restauración in situ.

Abstract. LDAS-Monde is a global offline land data assimilation system (LDAS) that jointly assimilates satellite-derived observations of
surface soil moisture (SSM) and leaf area index (LAI) into the ISBA (Interaction between Soil Biosphere and Atmosphere) land surface model
(LSM). This study demonstrates that LDAS-Monde is able to detect, monitor
and forecast the impact of extreme weather on land surface states. Firstly,
LDAS-Monde is run globally at 0.25∘ spatial resolution over
2010–2018. It is forced by the state-of-the-art ERA5 reanalysis
(LDAS_ERA5) from the European Centre for Medium Range Weather
Forecasts (ECMWF). The behaviour of the assimilation system is evaluated by comparing the analysis with the assimilated observations. Then the land surface variables (LSVs) are validated with independent satellite datasets
of evapotranspiration, gross primary production, sun-induced fluorescence and snow cover. Furthermore, in situ measurements of SSM, evapotranspiration
and river discharge are employed for the validation. Secondly, the global
analysis is used to (i) detect regions exposed to extreme weather such as
droughts and heatwave events and (ii) address specific monitoring and
forecasting requirements of LSVs for those regions. This is performed by
computing anomalies of the land surface states. They display strong negative
values for LAI and SSM in 2018 for two regions: north-western Europe and the Murray–Darling basin in south-eastern Australia. For those regions, LDAS-Monde is forced with the ECMWF Integrated Forecasting System (IFS) high-resolution operational analysis (LDAS_HRES, 0.10∘
spatial resolution) over 2017–2018. Monitoring capacities are studied by
comparing open-loop and analysis experiments, again against the assimilated observations. Forecasting abilities are assessed by initializing 4 and 8 d LDAS_HRES forecasts of the LSVs with the
LDAS_HRES assimilation run compared to the open-loop
experiment. The positive impact of initialization from an analysis in
forecast mode is particularly visible for LAI that evolves at a slower pace
than SSM and is more sensitive to initial conditions than to atmospheric
forcing, even at an 8 d lead time. This highlights the impact of initial
conditions on LSV forecasts and the value of jointly analysing soil moisture
and vegetation states.
Citizens against Domination: A Critical Reading of Ian Shapiro
Authors: Levine Peter
Published: September 2020

This review endorses Ian Shapiro's theory of nondomination but argues that he errs in attributing domination almost entirely to the state and by advocating (as the main or only strategies for reducing domination) changes in our systems of formal governance. This review argues that the lines between state and society are porous and indistinct, that domination—but also creativity and agency—arise in all sectors of a society, and that citizens should combat domination instead of hoping that the state is reformed.
Rage, Resistance, and Politics against Oppression
Authors: Ackerly Brooke
Published: September 2020

This article argues that a politics against domination needs to take on oppression (violence, exploitation, marginalization, powerlessness, cultural imperialism, and epistemic injustice) and that doing so requires attending to the rage and resistance of those oppressed. Politics against Domination does not. However, the adaptive approach to political theory, which Ian Shapiro advocates and models in the book, could lead us to modifications of the institutions and practices of politics against domination if it were more thoroughly informed by the politics of rage and resistance cultivated into and in social movements. Politics against Domination is full of cautions against progressives' institutional proposals (strengthening separation of powers, courts, and deliberation in the Senate) because they may not consistently create obstacles to domination, but rather be conduits for it or obstacles to redressing it. Proceeding cautiously given this concern, I offer some institutional renovations that might support the hearing of marginalized views.
On Deliberation against “Domination”
Authors: Fishkin James
Published: September 2020

This essay contrasts Ian Shapiro's neo-Schumpeterian ideal of competitive democracy with deliberative democracy. Shapiro contends that party competition will lead to a competition of ideas and will minimize what he calls “domination.” I contend that deliberative democracy is more promising as an aspiration to realize competition of ideas and the minimization of domination. In fact, Schumpeterian party competition is likely to produce hyperpolarization and incentives for propaganda and manipulation—hardly a genuine competition of ideas. And such competitive democracy may actually lead to domination by fostering populist movements bent on sacrificing the essential interests of minorities.
Reply to Ackerly, Boyte, Fishkin, Levine, and Warnke
Authors: Shapiro Ian
Published: September 2020

Here I reply to critiques of my 2016 book Politics against Domination set forth by Brooke Ackerly, Harry Boyte, James Fishkin, Peter Levine, and Georgia Warnke. Among the themes addressed are different ways of managing power relations in public and civil institutions; the relevance of lived experiences of those involved in power relations for evaluating them; the efficacy of social movements as vehicles for lasting social change; the advantages and limitations of competitive democracy, deliberation, and judicial review in combating domination; the economic and political sources of populism; and the virtues and limitations of identity politics, particularly for vulnerable minorities.

A practice-oriented method for estimating elastic floor response spectra
Authors: Haymes Kieran , Sullivan Timothy , Chandramohan Reagan
Published: September 2020

A practice-oriented modal superposition method for setting elastic floor acceleration response spectra is proposed in this paper. The approach builds on previous contributions in the literature, making specific recommendations to explicitly consider floor displacement response spectra and accounts for uncertainty in modal characteristics. The method aims to provide reliable predictions which improve on existing code methods but maintain simplicity to enable adoption in practical design. This work is motivated by recent seismic events which have illustrated the significant costs that can be incurred following damage to secondary and nonstructural components within buildings, even where the structural system has performed well. This has prompted increased attention to the seismic performance of nonstructural components with questions being raised about the accuracy of design floor acceleration response spectra used in practice. By comparing floor acceleration response spectra predicted by the proposed method with those recorded from instrumented buildings in New Zealand, it is shown that the proposed approach performs well, particularly if a good estimate of the building’s fundamental period of vibration is available.
Dynamic Instability of a Wind Turbine Blade Due to Large Deflections: An Experimental Validation

Published: September 2020

Wind turbine blades are designed to be thin and flexible elements. Because unstable dynamic behaviour can affect the life of the rotor, it is crucial to understand the instability of non-linear behaviour caused by large deflections. The present study undertakes both a stability analysis of the non-linear response and an experimental validation of a simplified model for a wind turbine blade based on a cantilever beam. The model is formulated taking into account large geometric deflections and assuming a Galerkin approach. The model is validated experimentally in a wind tunnel with aluminium beams of differing geometry. Analysis of the dynamic response using phase planes reveals that the degree of instability is related to the amplitude of the excitation and the stiffness characteristics.
Numerical Analysis with Experimental Validation of Single-Phase Fluid Flow in a Dimple Pattern Heat Exchanger Channel
Authors: Močnik Urban , Blagojevič Bogdan , Muhič Simon
Published: September 2020

A plate heat exchanger with a dimple pattern heat plate has a large number of dimples. The shape of dimples defines the characteristics of the plate heat exchanger. Although such heat exchangers have become increasingly popular due to their beneficial characteristics, knowledge of the flow characteristics in such kind of channel is poor. A good knowledge of the flow conditions inside of such channel is crucial for the successful and efficient development of new products. In this paper single-phase water flow in dimple pattern plate heat exchanger was investigated with application of computational fluid dynamics and laboratory experiments. Numerical analysis was performed with two turbulence models, Realizable - with enhanced wall treatment function and - SST. The first predicts a slightly smaller pressure drop and the second slightly larger compared to the results of laboratory measurements. Our research found that despite the relatively low velocity of the fluid, turbulent flow occurs in the channel due to its shape. We also found that there are two different flow regimes in the micro plate heat exchanger channel. The first regime is the regime that dominates the heat transfer, and the second is the regime where a recirculation zone appears behind the brazing point, which reduces the surface for heat transfer. The size of the second regime does not change significantly with the velocity of the fluid in the volume considered.

De rechtsstaat in discussie

Volgens de Raad van State zou de rechtsstaat in Nederland niet wezenlijk in gevaar zijn, zou de balans tussen de instituties die invulling moeten geven aan de rechtsstaat (wetgever, bestuur en rechter) tot nu toe verzekerd zijn en zou er voldoende draagvlak onder de bevolking bestaan. Daarom zou er ook geen reden zijn voor een ‘alarmerende toon’. Deze stellingen worden nauwelijks onderbouwd, staan maatschappelijk ter discussie en miskennen dat Nederland geen eiland is, maar onderdeel uitmaakt van een meergelaagde internationale rechtsorde. Het beeld dat de Raad daarbij heeft van de scheiding der machten behoeft dringend bijstelling.
Frequent Change of Land-Use Pattern and Its Effect on Ecology and Ecosystem in the South-West Coastal Area of Bangladesh
Authors: Rani Barai Krishna
Published: September 2020

The ecosystem of the South-West coastal area of Bangladesh is resourceful and unique. Regrettably, this distinctive area is vulnerable to numerous climatic factors, for instance, sea water intrusion, temperature variation, unpredictable behavior of rainfall, and frequent occurrence of cyclones and drought. Undesirably, the effects of those climatic factors have been enhancing on account of human behavior, one of which is the frequent change of land-use pattern in this area. The land-use pattern of the coastal Bangladesh has been changed continuously over the last 60 years in order to increase the agricultural production for improvement of livelihood. The unrealistic improvement projects (coastal embankment project, increased unscientific shrimp cultivation, and so on) brought the unforeseen disaster in the area. As a result, the salinity level of the area has been increased considerably, resulting in decreased production of different kind of crops and vegetables. Unstable economy and the emergence of calamities, leading to damage to ecology and ecosystem, made livelihood insecure in the area.

International health security (IHS) encompasses any natural or anthropogenic occurrence that can threaten the safety of human health and well-being. The American College of Academic International Medicine IHS Consensus Group (ACAIM-CG) developed a summative assessment highlighting the main issues that can impact IHS including emerging infectious diseases; chronic health conditions; bioterrorism; planetary changes (volcanic eruptions, earthquakes, wildfires, and climate change); nuclear incidents; information and cyber health; industrialization; globalization; pharmaceutical production; and communication platforms (social media). These concerns can directly and indirectly impact IHS both in the long and short term. When considering IHS, we aim to emphasize the utility of applying a predefined framework to effectively approach health security threats. This framework comprises of prevention, detection, assessment, reporting, response, addressing needs, and the perpetual repetition of the above cycle (inclusive of appropriate mitigation measures). It is hoped that this collective work will provide a foundation for further research within the redefined, expanded scope of IHS.
Late Cenozoic Collisional Volcanism in the Central Part of the Lesser Caucasus (Azerbaijan)

The chapter is devoted to petrogeochemical features of late Cenozoic collision volcanism of the Lesser Caucasus. It was determined that at the early and middle stages of crystallization of the rocks of the andesite-dacite-rhyolite association, amphibole fractionation played an important role in the formation of subsequent differentials. On the basis of computer modeling, it was found that when mixing andesite and rhyolite (taken as a contaminant) magma, it is possible to obtain a rock of dacitic composition. Under conditions of high water pressure, as a result of fractionation of olivine and pyroxene from primary high magnesian magma, high-alumina basalts are formed, which can be considered as the parent magma.Geochemical features of moderately alkaline olivine basalts indicate that the source of magma is metasomaticized, phlogopite-garnet-rutile containing lithospheric mantle. The evolution of moderately alkaline olivine basalts occurs due to changes in the composition of the main rock-forming and accessory minerals. Medium rock formations are formed by the assimilation of poorly differentiated primary magma by an acidic melt. The calculations have shown that proportion of melting rhyolitic melt separated from andesite substrate is close to 15%. After removal of the remaining melt, restite is entirely consistent with the composition of the lower earth crust.

Nanoadditives are a type of heat transfer enhancement techniques adopted in heat exchangers to improve the performance of industrial plants through improvement of the thermal properties of base fluids. Recently, various types of inserts with nanofluids are adopted to enhance the thermal performance of double pipe heat exchangers. In the current article, TiO2/water nanofluid with multiple twisted tape inserts was investigated as a hybrid enhancement technique of heat transfer in straight pipes. The investigations were carried out experimentally and numerically at Reynolds numbers varied from 5000 to 20,000. Using nanofluid with 0.1% TiO2 nanoparticles volume fraction demonstrated enhanced heat transfer with slight increase in pressure drop. Results are showing a maximum increase of 110.8% in Nusselt number in a tube fitted with quintuple twisted tape inserts with 25.2% increase in the pressure drop. However, as the article is representing a part of specified book on heat exchangers, the literature has been extended to provide sufficient background to the reader on the use of nanotech, twisted inserts, and hybrid of compound nanofluids and inserts to enhance heat transfer processes.

Published: September 2020

Three kinds of Bi-related materials co-doped silica optical fibers (BRDFs), including Bi/Al, Bi/Pb, and Bi/Er co-doped fibers, were fabricated using atomic layer deposition (ALD) and modified chemical vapor deposition (MCVD). Then, the effect of irradiation on the optical properties of BRDFs was investigated. The experimental results showed that the fluorescence intensity, the fluorescence lifetime of BRDFs at the 1150 nm band, increased significantly with low-dose treatment, whereas it decreased with a further increase in the radiation dose. In addition, the merit Mα values of the BRDFs, a ratio of useful pump absorption to total pump absorption, decreased with an increase of the radiation doses. The Verdet constants of different doped fibers increased up to saturation level with increases in the radiation dose. However, for a Bi-doped fiber, its Verdet constant decreased and the direction of Faraday’s rotation changed under low-dose radiation treatment. In addition, the Verdet constant increase of the Bi-doped silica fiber was much faster than that of other single mode fiber (SMF) and Pb-doped silica fibers treated with high-dose radiation. All of these findings are of great significance for the study of the optical properties of BRDFs.

Background: The impact of personality traits such as type D personality on the development of psychosomatic illnesses such as cancer has been found by many researchers in the field of health psychology. Objectives: The purpose of this study was to investigate the status of the type D personality trait and its relationship with perceived stress among women with breast cancer. Methods: This cross-sectional study enrolled 120 cancer patients during 2017. After applying the inclusion and exclusion criteria and obtaining informed consent, the patients were selected using the convenience sampling method and evaluated by the Type D Personality Scale (DS14) and Perceived Stress Scale (PSS). Results: In this study, 69.2% of the patients obtained a score of ≥ 29 in the DS14 questionnaire. Correlation analysis between the components of DS14 and the final score of PSS showed that both social inhibition and negative affectivity had direct correlations with perceived stress (r = 0.35 and r = 0.6, respectively; P < 0.001). Conclusions: One of the most important results of this study was a relatively high score of type D personality among patients with breast cancer and the high contribution of negative affectivity to the perceived stress by patients with this type of personality. The particular status of type D personality traits among cancer patients can be used to design psychotherapy programs for them to prevent disease progression.
