The blessing of dimensionality for the analysis of climate data
Authors: Christiansen Bo
Published: January 2021

Abstract. We give a simple description of the blessing of dimensionality with the main focus on the concentration phenomena. These phenomena imply that in high dimensions the length of independent random vectors from the same distribution have almost the same length and that independent vectors are almost orthogonal. In climate and atmospheric sciences we rely increasingly on ensemble modelling and face the challenge of analysing large samples of long time-series and spatially extended fields. We show how the properties of high dimensions allow us to obtain analytical results for, e.g., correlations between sample members and the behaviour of the sample mean when the size of the sample grows. We find that the properties of high dimensionality with reasonable success can be applied to climate data. This is the case although most climate data show strong anisotropy and both spatial and temporal dependence resulting in effective dimensions around 25–100.
Airborne mapping of the sub-ice platelet layer under fast ice in McMurdo Sound, Antarctica

Published: January 2021

Abstract. Basal melting of ice shelves can result in the outflow of
supercooled ice shelf water, which can lead to the formation of a sub-ice
platelet layer (SIPL) below adjacent sea ice. McMurdo Sound, located in the
southern Ross Sea, Antarctica, is well known for the occurrence of a SIPL
linked to ice shelf water outflow from under the McMurdo Ice Shelf.
Airborne, single-frequency, frequency-domain electromagnetic induction (AEM)
surveys were performed in November of 2009, 2011, 2013, 2016, and 2017 to
map the thickness and spatial distribution of the landfast sea ice and
underlying porous SIPL. We developed a simple method to retrieve the
thickness of the consolidated ice and SIPL from the EM in-phase and
quadrature components, supported by EM forward modelling and calibrated and
validated by drill-hole measurements. Linear regression of EM in-phase
measurements of apparent SIPL thickness and drill-hole measurements of
“true” SIPL thickness yields a scaling factor of 0.3 to 0.4 and rms error
of 0.47 m. EM forward modelling suggests that this corresponds to SIPL
conductivities between 900 and 1800 mS m−1, with associated SIPL solid
fractions between 0.09 and 0.47. The AEM surveys showed the spatial
distribution and thickness of the SIPL well, with SIPL thicknesses of up to
8 m near the ice shelf front. They indicate interannual SIPL thickness
variability of up to 2 m. In addition, they reveal high-resolution spatial
information about the small-scale SIPL thickness variability and indicate
the presence of persistent peaks in SIPL thickness that may be linked to the
geometry of the outflow from under the ice shelf.
Debris cover and the thinning of Kennicott Glacier, Alaska: in situ measurements, automated ice cliff delineation and distributed melt estimates
Authors: Anderson Leif S. , Armstrong William H. , Anderson Robert S. , Buri Pascal
Published: January 2021

Abstract. Many glaciers are thinning rapidly beneath melt-reducing
debris cover, including Kennicott Glacier in Alaska where glacier-wide
maximum thinning also occurs under debris. This contradiction has been
explained by melt hotspots, such as ice cliffs, scattered within the debris
cover. However, melt hotspots alone cannot account for the rapid thinning at
Kennicott Glacier. We consider the significance of ice cliffs, debris, and
ice dynamics in addressing this outstanding problem. We collected abundant in situ measurements of debris thickness, sub-debris
melt, and ice cliff backwasting, allowing for extrapolation across the
debris-covered tongue (the study area and the lower 24.2 km2 of the
387 km2 glacier). A newly developed automatic ice cliff delineation
method is the first to use only optical satellite imagery. The adaptive
binary threshold method accurately estimates ice cliff coverage even where
ice cliffs are small and debris color varies. Kennicott Glacier exhibits the highest fractional area of ice cliffs (11.7 %) documented to date. Ice cliffs contribute 26 % of total melt across
the glacier tongue. Although the relative importance of ice cliffs to area-average
melt is significant, the absolute area-averaged melt is dominated by debris. At Kennicott Glacier, glacier-wide melt rates are not maximized in the zone
of maximum thinning. Declining ice discharge through time therefore explains
the rapid thinning. There is more debris-covered ice in Alaska than in any
other region on Earth. Through this study, Kennicott Glacier is the first
glacier in Alaska, and the largest glacier globally, where melt across its
debris-covered tongue has been rigorously quantified.
Characterisation of intra-hourly wind power ramps at the wind farm scale and associated processes
Authors: Pichault Mathieu , Vincent Claire , Skidmore Grant , Monty Jason
Published: January 2021

Abstract. One of the main factors contributing to wind power forecast inaccuracies is the occurrence of large changes in wind power output over a short amount of time, also called “ramp events”.
In this paper, we assess the behaviour and causality of 1183 ramp events at a large wind farm site located in Victoria (southeast Australia). We address the relative importance of primary engineering and meteorological processes inducing ramps through an automatic ramp categorisation scheme. Ramp features such as ramp amplitude, shape, diurnal cycle and seasonality are further discussed, and several case studies are presented.
It is shown that ramps at the study site are mostly associated with frontal activity (46 %) and that wind power fluctuations tend to plateau before and after the ramps. The research further demonstrates the wide range of temporal scales and behaviours inherent to intra-hourly wind power ramps at the wind farm scale.
The Urinary Tract Microbiome in Male Genitourinary Diseases: Focusing on Benign Prostate Hyperplasia and Lower Urinary Tract Symptoms
Authors: Kim Myung Soo , Jung Seung Il
Published: January 2021

The human body is sterile during gestation; however, but during and after birth, the entire body surface becomes host to an enormous variety of microorganisms. Urine in the urinary tract was once considered sterile based on the lack of cultured microorganisms. Many recent studies have revealed evidence of microorganisms in human urine in the absence of clinical infection. Sequencing methods and analytical techniques are rapidly evolving to improve the ability to detect bacterial DNA and living bacteria and to understand the microbiota of the urinary tract. In women, fascinating evidence associates urinary tract microbiota with lower urinary tract symptoms. However, in men, the relevance of urinary tract microbiota in low urinary tract symptoms and prostate disease has not been established. In this review, we highlight a recent study that increases our ability to understand the urinary tract microbiota in men with lower urinary tract symptoms.

Published: January 2021

Entrapment neuropathy of the sciatic nerve and pudendal nerve are painful syndromes that are often overlooked by physicians. Laparoscopic surgical interventions for nerve entrapment syndromes of the posterior pelvis focus on removing the compression lesion with the purpose of eliminating the suspected cause of sciatica, as well as pudendal neuralgia. Herein, the authors report the rare event of sciatic and pudendal nerve entrapment, which was caused by aberrant vessels and a variant piriformis muscle bundle, as a seldom-diagnosed cause of sciatica and pelvic pain, for both neurosurgeons and neuropelveologists. The authors present the laparoscopic decompression technique for the pudendal and sciatic nerves by giving our technical “tips and tricks” enriched by a surgical video.

Nuestro objetivo fue comprobar si existían espacios de impunidad jurídica en barrios privados de Buenos Aires, Argentina. Se realizó una etnografía en algunos de estos espacios y se recurrió a fuentes secundarias para ampliar la investigación. Observamos que la inseguridad es una de las principales razones para vivir en estos espacios, pero dentro de ellos también existe criminalidad, solo que algunos lazos políticos permiten irresolución de tales crímenes. Esto es original ya que hay poca exploración respecto a esta temática y, en suma, como limitación puede indicarse la falta de bibliografía sobre este tópico.

Published: January 2021

Considering the importance of optimizing forest production, plant spacing is one of the most relevant silvicultural practices, as it holds ecological, silvicultural, and economic implications to the final product. Therefore, this study set out to assess the influence of spacing on the initial growth and production variables of hybrid clones of Eucalyptus urophylla S. T. Blake x Eucalyptus grandis W. Hill ex Maiden planted in a Nelder (fan-shaped) design. Plant densities ranged from 0.50 m² to 41.25 m² in area-per-plant. Variables such as total height, diameter, and volume were observed at 16, 24, and 36 months. A descriptive statistical analysis, Pearson’s correlation coefficient, and cluster analysis of averages were used to evaluate the effect of spacing on the variables in question. Different spacings were found to exert significant influences on growth in height, diameter, and volume.

Published: January 2021

The objective of this work was to determine the influence of different artificial diets on biological parameters related to the life cycle of C Condylorrhiza vestigialis aiming to determine the most suitable diet for the rearing of a population of this insect. Four diet formulations were tested. Ten repetitions were used, with 30 caterpillars per repetition. All stages of C. vestigialis life cycle were followed to evaluate biological parameters: viability of larvae, pre pupa, pupa and adults, as well as the sex ratio. The number of larval instars, the pupal mass and the total number of eggs per day and per female day were also calculated. The four diets tested allowed the development of C. vestigialis caterpillars. All diets were considered adequate for the purpose of the work, which is the production of baculovirus used in the control program of this pest. It was the diet 2 that provided the best results, the largest pupal mass, and the quantity and viability of the eggs produced by C. vestigialis females fed in this larval phase.

Influence of foundation compliance on the seismic response of bridge piers
Authors: Priestley M. J. N. , Park R. , Heng Ng Kit
Published: January 2021

The paper summarises the results of dynamic analyses of some single-stem and double-stem bridge piers responding to a range of earthquake ground motions, including both natural and synthetic earthquake records. The influence of foundation flexibility was modelled by an 'extended leg' analogy and by a more refined approach in which the soil is replaced by an equivalent spring system. A bilinear moment-curvature loop was assumed to model the plastic hinge behaviour. The curvature ductility factor demand of bridge piers with different foundation flexibilities was determined and compared with the rigid foundation case.

Authors: Sridharan Kannan , Al Banna Rashed , Husain Aysha
Published: January 2021

Background: Pharmacokinetics of warfarin has not been described in our population. We derived the pharmacokinetic parameters from a validated pharmacokinetic-pharmacodynamic model. Methods: Patients receiving warfarin for at least 6 months were recruited and their demographic characteristics, prothrombin time international normalized ratio (PT-INR), warfarin doses and concomitant drugs were collected. Using a validated pharmacokinetic-pharmacodynamic model, we predicted maximum plasma concentration (Cmax), total clearance (CL), volume of distribution (Vd) and elimination rate (k). Warfarin sensitive index (WSI) and warfarin composite measures (WCM) were estimated from the dose and INR values. Liver weight was predicted using validated formula. Results: Two-hundred and twenty patients were recruited. The following were the predicted pharmacokinetic parameters: Cmax (mg/L) was 5.8 (0.4); k (L/day) was 1 (0.1); CL (L/day) was 2.1 (0.2); and Vd (L) was 7.6 (0.2). Patients with Cmax and elimination rate outside the mean+1.96 SD had significantly lower WSI and higher WCM. Significant correlations were observed between Cmax with CL, Vd, and k of warfarin. Significant correlations were also observed between CL and Vd of warfarin with liver weight of the study participants. Conclusion: We predicted pharmacokinetic parameters of warfarin from the validated pharmacokinetic-pharmacodynamic model in our population. More studies are needed exploring the relationship between various pharmacodynamic indices of warfarin and pharmacokinetic parameters of warfarin.

Materiały antywibracyjne są od lat z powodzeniem stosowane w środkach ochrony indywidualnej, chroniących organizm przed drganiami przenoszonymi przez kończyny górne. Jednak w przypadku ochron indywidualnych przeznaczonych do redukcji drgań działających na człowieka w sposób ogólny (przenikających przez stopy, miednicę, plecy lub boki) rynek nie oferuje praktycznie żadnych rozwiązań. Jednym ze sposobów ochrony przed drganiami ogólnymi przenoszonymi przez stopy może być obuwie o właściwościach redukujących drgania. Zastosowanie materiałów antywibracyjnych w podpodeszwach bądź wyściółkach takiego obuwia może zmniejszyć transmisję drgań ze źródła do organizmu pracownika.
W artykule przedstawiono opracowaną w CIOP-PIB metodę oceny przenoszenia drgań mechanicznych przez elementy konstrukcyjne podeszwy (podpodeszwy, wyściółki) do zastosowania w obuwiu jako ochrony indywidualnej przed drganiami ogólnymi przenoszonymi przez stopy. Omówiono również wyniki przeprowadzonych badań modeli wyściółek/podpodeszew.

Authors: Delaviz Elham , Salehi Moosa , Ahmadi Afsane , Fararooei Mohammad , Vakili Mahdis , Ashjazadeh Nahid
Published: January 2021

Background: Multiple sclerosis (MS) is the most disabling neurological disease and has been studied for decades, but there are still many unproven treatments. Cinnamon (Cinnamomum zeylanicum) is a well-known herb and has many therapeutic applications. Objectives: This study aimed to evaluate the effect of cinnamon on inflammatory factors, pain, and anthropometric indices in patients with progressive-relapsing MS. Methods: In this randomized controlled trial, 60 patients suffering from progressive-relapsing MS were randomly recruited from Shiraz MS Center. Four capsules of cinnamon were taken every day for eight weeks by each participant in the intervention group (500 mg in each capsule) and four capsules of wheat flour by the control group (500 mg in each capsule). A 3-day 24-h food recall and physical activity questionnaire was filled out by interviewing before and after the intervention. Pain level was evaluated by using a Visual Analog scale (VAS). Interleukin-6 (IL-6) and high-sensitivity C-reactive protein (hs-CRP) were measured in blood samples before and after the intervention. Participants underwent anthropometric measurements, including body weight, height, and waist and hip circumference. Results: Thirty-six (87.80%) participants were female, and twenty-six patients were married (63.41%). IL-6 and hs-CRP levels decreased significantly in the intervention group compared to the control group (P < 0.05). According to the VAS results, the pain level also decreased significantly (P = 0.003) in the intervention group in comparison to the control group. Conclusions: Multiple sclerosis is a debilitating inflammatory disease, and cinnamon may help improve inflammatory markers and pain in MS patients.
Ciência, magia e filosofia em Eric Weil
Authors: Castelo Branco Judikael
Published: January 2021

Este artigo compreende relações entre os termos elencados no título a partir do texto “Science, magie et philosophie” de Eric Weil. Para tanto, ele se estrutura em três diferentes momentos. No primeiro, procuramos os fundamentos dos argumentos de Weil ao recolocar a relação entre ciência e magia como visões de mundo que coincidem naquilo que uma mantinha como promessa e que a outra alcançou como realização. Depois, vemos a passagem da theôria da ciência antiga à teoria das ciências modernas e as questões em torno da possibilidade de uma visão compreensiva da realidade. Por fim, tomamos a questão do sentido da magia moderna, reconhecendo o seu caráter irrecusável e, ao mesmo tempo, à necessidade da filosofia como condição para pensar o dilema da coexistência das demandas de uma civilização modelada pela ciência com a persistência das questões do sentido da vida humana.
Ideias para uma termodinâmica noética e uma noética ígnea
Authors: Valentim Marco Antonio
Published: January 2021

O ensaio desenvolve o problema cosmológico da relação entre metafísica e termodinâmica, pensamento e ambiente, espírito e calor, com foco nos conceitos filosófico- científicos de sistema (Serres, Bateson) e entropia (Prigogine & Stengers, Georgescu-Roegen), em vista da catástrofe ambiental em curso. Seu objetivo principal é fundamentar a hipótese mágico-filosófica, baseada em Ficino e Agrippa, Starhawk e Castaneda, segundo a qual uma termodinâmica noética, ou uma noética ígnea, é não só possível mas necessária para fazer sentido do Antropoceno como “Piroceno” (Pyne). Por sua origem antrópica, a catástrofe planetária atesta que o pensamento é intrinsecamente ígneo.

Este artigo parte de uma proposta terapêutica psicanalítica de cura pela fala e das premissas dos estudos a respeito de um performativo para conjurar referenciais e tecer considerações acerca do feitiço, tomando-o na sua dimensão de acontecimento singular e de natureza imprevisível. Esta discussão ocorrerá debruçada sobre os meios de um capitalismo e pautada a partir das ambivalências de uma ideia de fetiche. No ensejo desta discussão, são retomadas algumas colocações que elaboram sobre os interstícios entre magia e política para indicar a importância de uma dimensão incapturável no fazer científico.
Sonhos tirânicos e uma poção mágica para as opressões na cabeça de Cármides no diálogo (homônimo) de Platão
Authors: Pereira Bianca Vilhena Campinho
Published: January 2021

Sabendo que Cármides sofria com dores na cabeça pela manhã, Sócrates se oferece para curar a enfermidade do jovem e, em busca do fármaco para o tratamento, conta que, enquanto esteve em Potideia, recebera o ensinamento de certas práticas mágicas de um discípulo de Zalmoxis. Possíveis causas para as opressões na cabeça de Cármides já foram aventadas, como, por exemplo, a ressaca da embriaguez e a própria intemperança, objeto de análise do diálogo. O nosso propósito neste artigo é, além de sugerir a hipótese de que a moléstia se deve à qualidade de seus sonhos, destacar, dentre algumas práticas caracterizadas como mágicas, aquela que visa a cura por intermédio da liberação da alma do corpo, o que é assinalado pela excursão alçada pelo sono. Para corroborar a nossa hipótese, abordaremos passagens da República em que Platão, ao tratar da transformação do homem democrático em tirânico, menciona a psicologia dos sonhos.
A atitude fenomenológica e o “caminho do guerreiro”: aprendendo a “ver”
Authors: Moor Rudinei Cogo
Published: January 2021

A fenomenologia, como método filosófico, consiste primeiramente numa mudança de atitude, do “olhar natural” para o “ver essencial”. O caminho fenomenológico se inicia quando um fenômeno se mostra para a consciência segundo algum modo descritivo. Com a redução dos pressupostos ou interpretações, a fenomenologia se propõe a descrever o dado puro, a essência do que se dá em aparição. Numa descrição literária, podemos entender esse objetivo fenomenológico como a descrição do conhecimento da feitiçaria, ordenada por Carlos Castaneda em suas experiências incomuns de percepção. No presente artigo, pretendemos aproximar alguns pontos em comum entre feitiçaria e fenomenologia. Além do próprio Castaneda fazer referência direta aos conceitos fenomenológicos e utilizar seu método de descrição, o artigo mostra uma aproximação com o “ver”, que é o objetivo tanto do fenomenólogo quanto do feiticeiro.
Viagens aos Infernos: a experiência visionária como ensaio para uma filosofia pré e pós humanista
Authors: Perencini Tiago Brentam
Published: January 2021

Por que a experiência visionária perturba a filosofia (crítica)? Experimentando uma anarqueologia como procedimento de leitura, argumento que a relação entre filosofia e magia no curso da história ocidental pode ser encenada como uma peça paradoxal. Da mesma maneira que a filosofia racionalista conjura a magia, simultaneamente, tais saberes estiveram presentes de modo polifônico nos bastidores da encenação ilustrada. Para conjurar o demônio é necessário antes evocá-lo. Evoco, assim, o itinerário das viagens aos infernos ao qual certa visão xamanística de alma grega fecunda possibilidades para ensaiarmos um tipo de filosofia pré e pós crítica, onde a experiência visionária aparece posteriormente como pedra no sapato ao pensamento ilustrado, científico e humano. Exemplifico tal questão recorrendo à visão paradoxal de Immanuel Kant quando analisa as experiências visionárias de Emmanuel Swedenborg. Ao reconhecer contemporaneamente a nossa herança legítima como filhos da razão, será preciso reencarnar o lugar bastardo dos sonhos e da mediunidade exorcizada.
Age waves of baby boom and baby bust generations through arithmetic and geometric coefficients of population ageing in Serbia
Authors: Stojilković-Gnjatović Jelena , Devedžić Mirjana
Published: January 2021

Age waves is theoretical concept that take into account the importance of disordered cohort flows, mainly as by-product of demographic transition (fluctuating fertility and improved survival), but also external factors (especially wars). The primary age wave as a consequence of high births after the Second World War in Serbia did not remain an isolated phenomenon, but created a secondary cohort wave although the fertility indicators were declining, which is visible as the thickening of the pyramid base in 1981 due to the absolute increase in births. Cohort "tide" has influenced the shape of the pyramid to longer retain the properties of the stationary type because the baby boom generation reproduced the "echo" generation, which is a counterbalance to extreme demographic aging as the baby boom generation entered the contingent of the old population. A cohort analysis of the elderly population shows that the declining share of the elderly in a certain age group is typical for cohorts born during turbulent times, most often wars, while cohorts born afterwards form more numerous generations. A half-century characteristic of the Serbian population is an absolute increase of people older than 65, but it does not automatically mean an adequate increase in the relative share of the elderly because it depends on the number of other age groups and their cohort trajectories. The methodological tool that can valorize heterogeneity of the old population is important for societies with past oscillations in fertility and migratory movements. In this study, the usefulness of the arithmetic and geometric coefficients of aging was tested on the example of baby boom and baby bust generations and their position in the old population, revealing periods when rejuvenation or aging of the old has dominated.
Gender roles and education as elements for the explanation of fertility by the type of settlement in Serbia
Authors: Šobot Ankica
Published: January 2021

This text is aimed at the consideraton of differences related to fertility of urban and non-urban settlements in Serbia, from the point of view of differentiation concerning education and gender roles. The discussion framework consists of the results of relevant empirical researches that consider gender equality, as well as the presented data about level of education for both types of settlements. In terms of fertility, we used census data and presented two indicators. These are the cumulative live birth rates and the shares of women who have not given birth. The focus is on the generations born in the second half of the 20th century, observing the cohorts that are in the reproductive period, as well as those that came out. Differences between urban and non-urban settlements are not only observed for Serbia as a whole, but are also placed within the framework of statical regional areas. The decline in cumulative fertility, the postponement of parenthood and the shares of women without children both in the optimal reproductive period and in the cohorts at the end of reproductive period are more pronounced in the urban population. However, these tendencies also have existed in non-urban settlements, despite the fact that the observed fertility indicators do not reflect the difficulty of regulating low fertility in this type of settlement. Very low cumulative fertility rates in the urban settlements are the result of insufficient adjustment of the institutional framework to emancipatory processes in the sphere of gender roles. The negative effects of traditional patriarchy in non-urban settlements are more visible through some other demographic indicators that are closely related to the issue of low fertility. Hence, the importance of the gender aspect cannot be neglected when it comes to non-urban settlements.
The use value of preschool institution space as a element of socio-demographic development

Published: January 2021

The aim of the paper is a critical sociological analysis of the space of preschool institutions and the design the capacity of the space of preschool institutions, in accordance with the norms proposed within the European social model and the Master Plan of Belgrade. In accordance with the model assumptions, the practice of recommended norms is expected to produce transformational potential by initiating a chain of positive changes, starting with the elimination of systemic risks through decommodification of care for preschool children and production of politically correct space of higher use value, through increasing the coverage of the preschool contingent by state primary schools, to a favorable impact on stimulating birth. Paper Subject -use value of preschool institutions in Serbia, and the Belgrade municipalities Zvezdara and Savski Venac. Statistical analysis, preschool institutions spatial capacity analysis, comparative method, critical analysis were the analysis used in this paper. The following indicators were used to measure the use value of preschool institutions space: percentage of children attending preschools in Serbia, percentage of children attending preschools according to the type of preschool ownership, percentage of children attending public preschools, compliance of the available space in public preschools in the municipalities of Zvezdara and Savski Venac with the valid norms. The final section contains a proposal of spatial capacities which are believed to have sufficient transformational potential, for the purposes of initiating the positive chain of changes in the direction of sustainable social and demographic development.
Hatsune Miku: The subversive potential of a participatory-created cyberpop idol
Authors: Mrđenović Maja
Published: January 2021

Virtual worlds and online interactions are the base of cyberpop culture, in which consumption also causes production of meaning. It possibly can, but does not have to bring out subversive and/or activist potential. The overflow of the virtual into the spaces of physical reality, by use of technologies as gestural interfaces, holographic projections and the like, allows direct bodily interactions with virtual objects. Some of these objects are so-called virtual idols. Their appearance, identity and celebrity status are constructed and assigned by real people in the real world. This paper analyses the role of fans in the creation of the most famous virtual idol, the vocaloid Hatsune Miku. Based on this analysis, the paper puts forward a thesis that existence of Hatsune Miku puts emphasis on the activity (participation) per se, instead of activism. It does not serve the idea of social change, but the maintaining of the social status quo.
Wheat varieties productivity at different sowing dates
Authors: Veliborović Milica , Kolarić Ljubiša , Živanović Ljubiša , Ikanović Jela
Published: January 2021

The aim of this research is to study two important factors in wheat production (Triticum sp.) - sowing time and variety, specifically their influence on wheat yield and yield components: the number of grains per spike, grain weight per spike, 1,000-grain weight, and the hectoliter weight. The influence of sowing time and variety were determined based on the obtained data, which indicated the extent to which the significance of these factors manifest on certain components and wheat yield. The optimal sowing date is October 5th-25th. The variety itself cannot give a high yield without the application of all agrotechnical measures, to which we strive for primarily due to the high wheat importance. The experiment set up by the split-plot method in three replications examined three wheat varieties: Gabrio, Rapsodija and Basmati sown in two sowing dates: October 29th and November 25th. The results showed that all yield components (the number of grains per spike, the grain weight per spike, the 1,000 - grain weight, and the hectoliter weight) had the highest values in Rapsodija variety and were more dependent on the variety than to sowing time. The influence of the variety on the hectoliter mass was at a significant level. Wheat yield depended more on sowing time, and the influence of sowing time, variety, and interaction of these two factors on yield were statistically significant. The highest yield was registered in Gabrio variety (8.87 t ha-1), while the average yield achieved by this micro experiment was 8.46 t ha-1.
Gubernamentalidad liberal, evaluación y verdad: Sobre el uso político del conocimiento técnico
Authors: Rivero Recuenco Ángel
Published: January 2021

La evaluación de intervenciones públicas constituye una disciplina técnica cuya finalidad es informar la toma de decisiones gubernamentales. Por ello, resulta especialmente relevante para analizar el problema del uso político del conocimiento. En este sentido, la historia de esta disciplina pone de manifiesto el enfrentamiento entre paradigmas metodológicos en cuya pugna están en juego distintos modos de aplicar los resultados de las evaluaciones. Asimismo, se evidencian las dificultades y distorsiones de esta puesta en práctica, el incumplimiento persistente de los fines asignados a la evaluación. Ello plantea una paradoja: el sentido último de la evaluación es incrementar la eficacia y la utilidad de la acción gubernamental; sin embargo, comparece como una práctica inútil, sin uso efectivo. El presente artículo indaga en las razones de esta paradoja desde una doble perspectiva, constituida por la concepción foucaultiana del acoplamiento entre saberes y dispositivos de gobierno, y las reflexiones de Hannah Arendt sobre la relación entre verdad y política en las sociedades contemporáneas.The evaluation of public interventions is a technical discipline whose purpose is to inform government decision-making. Therefore, it is especially relevant in order to analyze the problem of the political use of knowledge. In this sense, the history of this discipline shows the confrontation between methodological paradigms in whose struggle different ways of implementing the results of evaluations are at stake. Likewise, the difficulties and distortions of this implementation are evidente: the persistent non-compliance of the purposes assigned to the evaluation. This raises a paradox: the ultimate meaning of evaluation is to increase the effectiveness and utility of government action; however, it appears as a useless practice, a practice without effective use. The present article explores the reasons for this paradox from a double perspective, constituted by the Foucaultian conception of the coupling between knowledge and government devices, and the reflections of Hannah Arendt on the relationship between truth and politics in contemporary societies.

Naturalismo universal: una descripción filosófica
Authors: Rada García Eloy
Published: January 2021

La constatación de que nuestro universo está constituido (aparentemente) de unos y los mismos elementos materiales en cualquier lugar en que podamos observarlo nos lleva directamente a la postulación de un único principio y causa del único proceso universal al que se debe cuanto existe. Y en ese trance parece inevitable preguntar: ¿cómo ha surgido Todo? Todo, aquí, significa cuanto hay; sin excepción alguna. Esta visión puramente física del Universo puede denominarse naturalismo universal, entendiendo el término naturalismo como traducción del término aristotélico physis en su célebre definición
Investigaciones de Eloy Rada sobre Leibniz
Authors: Echeverría Ezponda Javier
Published: January 2021

Este artículo analiza las aportaciones que Eloy Rada hizo a los estudios leibnicianos a través de sus ediciones de textos de Leibniz (1980 y 2016) y al analizar la confrontación entre Leibniz y los newtonianos: polémica sobre el origen del Cálculo y el Análisis Matemático a finales del siglo XVII y contraposición entre las teorías del espacio y el tiempo de Newton y Leibniz. Rada mostró que el sistema newtoniano tenía una fundamentación teológico-religiosa, que fue puesta en cuestión por el sistema leibniciano de la armonía preestablecida, haciendo irreconciliables las posturas de ambos. Las divergencias, incluida la discusión sobre la fuerza de la gravedad, son consecuencia de esa contraposición metafísica y teológica, que afectaba a las raíces de la religión anglicana, tal y como se había conformado a partir del latitudinarismo de los filósofos de Cambridge, de Boyle y del propio Newton y su sistema de la gravitación universal.
La influencia de Suárez en la metafísica de Leibniz
Authors: Escribano Cabeza Miguel , Nicolás Marín Juan Antonio
Published: January 2021

Se plantea el problema de la influencia de Suárez en la concepción de la individualidad por Leibniz. Para ello se analiza principalmente la Disputatio Metaphysica de principio individui de Leibniz. Se diferencian tres posturas: tomista, scotista y suareziana. Se confronta la idea de ‘forma’ de Leibniz con la de Aristóteles y la idea de ‘forma sustancial’ con la escolástica y Suárez. La comparación de Leibniz con Suárez se centra en la noción clave de “forma sustancial” y se analizan sus diversos significados. Se formula la coincidencia de ambos autores en torno a la tesis de que la individuación tiene lugar en virtud de la “entidad total”. Finalmente se analiza el significado exacto de esta expresión y se señalan las diferencias entre ambos autores, especialmente las que se producen en la evolución final de Leibniz. Ahí se introduce la concepción de la forma sustancial como principio vital que cohesiona los cuerpos.

Authors: Suárez Muñoz Rosa María , Ortiz Camacho María del Mar , Baena Extremera Antonio
Published: January 2021

Resumen: El vestuario teatral, en la génesis de un proyecto escénico de danza, se considera un elemento más cuya importancia radica en su significación. El objetivo general de este trabajo ha sido constatar la importancia del traje escénico como herramienta transmisora de conceptos y como elemento simbólico que aporta un sentido a la interpretación de la Danza Española. Se ha estudiado el uso de este vestuario desde una perspectiva profesional (Ballet Nacional de España (BNE), intérpretes y coreógrafos de reconocido prestigio) y desde una perspectiva educativa (Conservatorios Profesionales de Danza de Andalucía-España (CPDA)). Se ha realizado una triangulación metodológica combinando investigación cuantitativa y cualitativa utilizando como instrumentos básicos el cuestionario y entrevistas previamente validadas. Como conclusión, resalta la importancia otorgada al uso del vestuario teatral en la Danza Española como herramienta comunicativa intencional, así como su aportación a la interpretación en la representación escénica, confirmándose así las hipótesis planteadas.Abstract: The theatrical costumes, in the genesis of a scenic dance project, are considered one more element whose importance lies in its significance. The aim of this paper has been to verify the importance of it as a communicating tool of concepts and as a symbolic element that contributes a sense to the interpretation of Spanish Dance.The use of this costume has been studied from a professional perspective (National Ballet of Spain (BNE), renowned performers and choreographers) and from an educational perspective (Professional Dance Conservatories of Andalusia (Spain) (CPDA)),making a methodological triangulation that combines quantitative and qualitative research, using the questionnaire and previously validated interviews as basic instruments. As a conclusion, the importance given to the use of theatrical costumes in Spanish Dance as an intentional communicative tool stands out, as well as their contribution to the interpretation in the scenic representation, confirming the hypotheses raised.
Las políticas supranacionales de educación superior ante la «tercera misión» de la Universidad: el caso del aprendizaje-servicio
Authors: García-Gutiérrez Juan , Corrales Gaitero Carlos
Published: January 2021

The constant transformation that the institutions of higher education experiment and, particularly, the university assumes a re-consideration of their shapes, methodology, and missions, as well as the relationships established with society. Therefore, we shall consider that a “social mission” of the university or their “third mission” constitutes an umbrella that shelters a wide diversity of reflex conceptions, and at the same time, the relationship university – society. Additionally, take into consideration that this civic and social commitment in higher education should incorporate an integrator approach, involved with an idea of European or Latin-American citizenship, in any case, incorporated in the development of their supranational policies. Therefore, the objective of our work is double. On one side, to meet and analyze the notion of a “social mission” or “third mission” of the university and their conceptual network, to clarify the language and in which sense the different denominations are used, according to the different economical, sustainability or civic approaches to be adopted. Secondly, the treatment of these ideas will be addressed at the supranational policies of higher education both in Europe and Ibero America, according to what had been structured at the Higher Education European State and whether it has been promoted by the OEI. Also, it will be attended the way that this supranational policy aboard the civic and identity components, that linked to the social mission cooperate for the promotion of common citizenship. As a result of the analysis made we can affirm that the approach of the learning-service constitutes an emergent tendency on a global scale, appropriate to develop effectively the third mission or social mission of the university.
Tendencias privatizadoras del modelo de financiación de la educación superior en Europa. Propuestas de la Unión Europea y el análisis del acceso asequible.
Authors: Carrasco González Alexandra
Published: January 2021

The influence exerted by supranational organizations, such as the European Union (EU) in the configuration of educational policies, forces us to include the supranational sphere in the study of educational trends. A growing trend in the field of higher education is the increase in private investment and our objective is to measure its impact in recent years in the European context and if it puts at risk the affordable access to this educational level. To do this, in the first place, we analyze the different actions developed from the European Union on increasing private financing of higher education through various documents and work plans. Second, from the Comparative Education methodology, we compare the variation in the sources of financing for higher education in European countries, over a 13-year trajectory (2002-2016), and its impact on affordable access to education higher, through the analysis of economic rates and student aid systems. The results, on the one hand, indicate that the EU justifies the increase in private financing of universities, as a global strategy to achieve greater competitiveness within the context of the knowledge society. On the other hand, there is a trend towards the privatization of financing models for higher education in European countries, which countries such as Ireland, Spain, Italy and Portugal, put at risk the affordable access to HE.
Educación Supranacional y Educación Superior: claves de transformación global para sociedades complejas
Authors: Valle López Javier Manuel , Pedró Francesc
Published: January 2021

Those of us who coordinated this monograph, and singed this presentation, sought to address some issues we considered relevant regarding the alignment between Supranational Education and Higher Education. We wanted to match some hypothesis we initially had and that we tried to synthesize in the title of this article. We have been able to find evidences related to an increasingly stronger direct impact between the education policy of international organizations – analyzed from the Supranational Education – and the higher education institutions. That impact is increasingly broader from a threefold perspective: from the geographic perspective – with large regions of the planet, in a globalization context, affected by supranational trends -; from an intensity perspective – as the effect is increasingly inevitable by the higher education institutions-; and from a tematic perspective – as it increasingly covers a greater number of topics.We also confirmed that these impacts have had a broad effect on social change. The assumption of new mercantilist paradigms of the new approaches to quality, the social mission of higher education, or gender issues directly affect citizens’ lives. And they do so from global perspectives. Thus, we verify what we suggested in the title of this modest contribution to the monograph, that the Supranational Education and the Higher Education can be keys to global transformation for the complex societies in which we currently live: as frameworks to understand the changes and as levers to promote them.
