Published: December 2019

This study focused on developments that occurred in gambus music in the Pariaman area from 1960 to 2018. Many other interesting changes that occurred in the development of stringed music in this area. Lute music is a musical unit that presents musical instruments gambus, especially playing Arabic songs and qasidah. The development of lute music in Indonesia began in the 19th century along with the arrival of Arab immigrants from Hadramaut, South Yemen to the archipelago. Although initially gambus was a means of preaching immigrants, along with the gambus, it developed into a means of entertainment. In 1970, Nur El-Surayya Gambus Orchestra held a concert in the context of a cultural weekend in Padang Pariaman District, West Sumatra. Nur El-Surayya Gambus Orchestra performances at that time were very welcome for the people of Padang Pariaman. Several years before the arrival of the Nur El-Surayya Gambus Orchestra to Padang Pariaman Regency, in this area several gambus music groups were established which are well known today, namely: Al Falah Gambus Orchestra (1960-1980), Al Ihsan (1965) , Nurul Hidayah (1974), and Al Hidayah (1995-present). The musical instrument used by the Al Falah Gambus Orchestra is currently an acoustic music instrument such as: violin, gambus (Ud), tamburin, bass barge / betot bass, and maracas. This study specifically examines the "Deculturation of the Forms of Performing Gambus Orchestra in the City of Pariaman, Province of West Sumatra, Musicological Study" using qualitative research methods. data collection used in this study are, observation, interviews, documentation and data analysis.

Authors: Syarip Robi , Hetami Fatma
Published: December 2019

Hope and Fear are something that lies in the deep of the human mind that affect how people act. This research is conducted to reveal fear and hope in society as part of human psyche that build its very foundation. The topic of this research is hope and fear in Stephen King’s The Mist. The research instrument uses observation sheets, while the data collection is based on the library research. This is a descriptive qualitative research that used structuralism theory by Levi-Strauss. By using the structuralism theory, the analysis of the study was conducted through binary opposition found in the novel. This research results in several findings as follows: 1) People lose themselves as human when fear constantly breaks them, while hope is the one that can keep them as human even in the hard times. 2) In religion aspect, fear has changed the way people think about God. The disaster, the death, and the monster are said to be God’s will. It shows that the fundamental of belief is changed from blessing life to cursing life. Furthermore, society’s moral has degenerated that they justify the wrong thing as right, and otherwise because they only think about their safety.

Aportes de Bartolomé de las Casas a la teoría actual de los derechos humanos
Authors: Pino Montoya Jose Wilmar
Published: December 2019

La tesis principal de este trabajo es argumentar que los principios pensados por Bartolomé de las Casas que le sirvieron para defender los aborígenes de América de los actos de los españoles, parten del concepto filosófico de hombre y de los argumentos sustraídos, principalmente de la tradición aristotélica, las teorías de Tomas de Aquino, Francisco de Vitoria, del cristianismo y de su experiencia como clérigo y encomendero en las tierras americanas. Por otra parte, sustentar que aun su pensamiento le aporta a la reflexión actual de los derechos humanos y a la construcción y consolidación de los Estados democráticos contemporáneos.
Marx, el cristianismo y la violencia de lo sagrado. Hacia una anamnesis de la teología de la liberación
Authors: Rivera Gómez Andrés Felipe
Published: December 2019

La figura de Karl Marx ha sido vista por algunos católicos como ateísta dada las expresiones tomadas fuera de contexto del pensador de Tréveris. No obstante, con rigurosidad el filósofo Enrique Dussel presenta una imagen muy diferente. Marx en realidad va a ser un crítico de los cristianos burgueses de su época, que confundieron el pensamiento de Jesús con un fetichismo bajo el cual terminaron sacrificando vidas inocentes. De hecho, llegaron a impulsar una violencia de lo sagrado que alcanza incluso hasta nuestros días. Por esta razón es fundamental hacer una relectura del pensamiento marxista desde la teología de la liberación para contribuir a la emancipación del ser humano de todo aquello que lo deshumaniza “en nombre de Dios”.
Hacia una enseñanza del locus de enunciación latinoamericano: un acercamiento a partir de los postulados de Juan José Bautista Segales
Authors: Suárez López Andrés Felipe
Published: December 2019

El presente artículo tiene como propósito presentar una reflexión pedagógica mediante la aplicación de referentes del pensamiento de Juan José Bautista, discípulo de Enrique Dussel. Se busca repensar en términos epistemológicos la enseñanza del locus de enunciación latinoamericano. Se tiene en cuenta que el proceso de desarrollo y consolidación de la razón moderna como forma de compresión de la realidad latinoamericana ha destruido sistemáticamente otras formas de pensar, incluidas las de los pueblos originarios americanos. Es por eso que este artículo busca introducir la reflexión sobre los compromisos que implican pensar y pertenecer a esta zona geográficamente diversa.
La guerra interna de Marx. Análisis de su intento por superar la teleología de la historia desde sus reflexiones sobre la periferia del mercado mundial capitalista
Authors: Macías Fernández Carlos Maximiliano
Published: December 2019

En los estudios de Marx sobre el modo de producción específicamente capitalista en la periferia, más allá de Europa occidental, encontramos un doble movimiento: sus estudios históricos configuran todo un campo de tensiones en el que podemos examinar sus posiciones políticas y teóricas entrecruzadas con los cambios y las contradicciones históricas del siglo xix. Analizando las opiniones de Marx sobre la cuestión colonial y la cuestión nacional en casos tan variados como los de India, América Latina, China, Irlanda, Polonia o Rusia comprobamos su distanciamiento creciente pero irregular con respecto al “sistema” hegeliano, que nunca dejó de inspirarlo, en un intento de superar la teleología de la historia. En cuestionamiento se encontraba el presupuesto de que las formas sociales superiores surgen del agotamiento y la aniquilación de las directamente inferiores. Aunque imperfecta, la superación de la teleología acercó a Marx al reconocimiento de la coexistencia en el espacio y en el tiempo de formas sociales heterogéneas, lo que apuntaba hacia una concepción diferente de la teoría y la acción política.
Forming of the institutional field of economic selfidentification Ukrainians at the conditions of Austria-Hungary empire
Authors: Verbova Oksana
Published: December 2019

The article explores the institutional conditions of the development of the national household in the West Ukrainian land as part of Austria-Hungary. Outlined the actuality of the national tradition of economic self-realization and self-identification in the crisis conditions of modern Ukraine. Pointed out the complex process of searching of the ways of stimulating the development of a modern national market economy that is required to create forming a new economic mentality of Ukrainians, educated on the values of the national tradition of economic self-identification.
The essence of the modernization changes of the institutional field with the entry of Galicia, Bukovina and Transcarpathia into the Austrian Empire at the end of the eighteenth century is revealed. In particular, the judicial reforms of Empress Maria Theresa during 1768–1776 were analyzed, which led to changes primarily in the field of formal rules of the game. The institutional changes in the fiscal sphere that became important for market development are revealed. The influence of the laws of Joseph II, which for the first time affirmed the status of a subject of law for the peasant, was substantiated. The significance of the Patent of Joseph II of April 5, 1782, which abolished serfdom as a personal dependence of the peasants on the landowners, was proved, as well as that of the Urban Patent of February 10, 1789, on the abolition of the serfdom and its replacement by money tax. The role of the Josephine peasant reforms in the formation of a new institutional field of national identity, social capital, and economic self-organization is substantiated. It is established that the decrees of Joseph II (1780–1787) on the introduction of public spies created the ground for the formation of proto-civil society.
The events of the "spring of peoples" and the abolition of the cornice in 1848 were characterized, which became an important stage of the institutional maturation of the basis of the national economic movement. Attention is given to the significance of the law modernization of September 7, 1848 on the elimination of the personal dependence of peasants on the former owners and granting them the rights of citizens. The author covers the formation of wealthy peasants at the expense of the parceling of the landownership, whose owners were not able to properly manage in market conditions. The conclusion is formulated about the importance of the national tradition of economic self-identification of Ukrainians in the conditions of the Austro-Hungarian Empire for the modern strategy of economic development of the Ukrainian state.
Dynamics and structure of Soviet Ukraine's foreign trade in the interwar period
Authors: Bodnarchuk Tetyana
Published: December 2019

The article is devoted to the historical and economic research of the dynamics and structure of Soviet Ukraine’s foreign trade activities in the 1920–1930’s. A large decrease in the intensity of Ukraine’s foreign trade during the period of «war communism» is revealed. The dynamics and structural changes of the domestic export-import flows by the Black Sea-Azov ports and land customs in the early 1920’s are characterized. In particular, the commodity structure of Ukraine’s foreign trade is analyzed, and the domination of its agrarian and raw nature components is revealed. The basic geographical directions of domestic freight flows are revealed.
The intensity of Ukraine’s foreign trade operations during the NEP is investigated. The dominant role of Odessa and Nikolaev ports, as well as Shepetivska land customs house in domestic export and import trade is revealed. The structure of freight flows from the Ukrainian territory is analyzed. It is revealed that the main export items were grain, crop and livestock products, ores, wood and others. It was found out that the geographical structure of domestic foreign trade was limited to the countries of Western Europe at the stage of the new economic policy. Raw materials and food were exported there, and machinery, equipment and consumer goods were imported.
The changes in physical volumes of Soviet Ukraine’s exports and imports during the first and second five year periods are characterized. The author emphasizes the diversified nature of the domestic export-import flows, while the dominant role of agricultural products and raw materials was preserved. Extension of geographical directions of domestic foreign trade ties is pointed out. It is proved that the absence of own statehood and the monopolization of the foreign trade by the Soviet government were important factors limiting the development of domestic economic potential.
Structural reforms in agricultural production and foreign food trade: the Ukrainian experience 1950-1960's
Authors: Gorditsa Karolina
Published: December 2019

The article is devoted to the problem of revealing peculiarities of mutual influence and interdependence of changes in the economic structure of Ukraine and its participation in international economic relations at different stages of historical development. The purpose of the study is to summarize the historical and economic generalization of the experience of structural transformation in domestic agriculture from 1950 to 1960 in the context of foreign trade in food.
It was revealed that the political need to resume bread exports after World War II was an important reason for the beginning of the reform of Soviet crisis-hit agriculture. The main directions of reforms are identified, such as the increase of public investments in the development of agrarian industry, reduction of taxes on producers, increase in state procurement prices for agricultural products, expansion of the acreage through the development of virgin lands, sharp increase in corn output, and advanced development of animal husbandry.
It was found that the reduction of administrative pressure on producers, their increased material incentives and improvement of technical support of the enterprises caused a temporary economic recovery in the agrarian sector. It is proved that the curtailment of this policy due to the lack of domestic sources of financing and the predominance of extensive forms of management led to a slowdown in the development of agriculture, an increase in its crisis phenomena and the formation of dependence on food imports. Proposals are made on possible directions of using elements of historical experience gained in contemporary economic policy of Ukraine.

Published: December 2019

Pediatricians aspire to optimize overall health and development, but there are no comprehensive measures of well-being to guide pediatric primary care redesign. The objective of this article is to describe the Cincinnati Kids Thrive at 5 outcome measure, along with a set of more proximal outcome and process measures, designed to drive system improvement over several years. In this article, we describe a composite measure of “thriving” at age 66 months, using primary care data from the electronic health record. Thriving is defined as immunizations up-to-date, healthy BMI, free of dental pain, normal or corrected vision, normal or corrected hearing, and on track for communication, literacy, and social-emotional milestones. We discuss key considerations and tradeoffs in developing the measure. We then summarize insights from applying this measure to 9544 patients over 3 years. Baseline rates of thriving were 13% when including all patients and 31% when including only patients with complete data available. Interpretation of results was complicated by missing data in 50% of patients and nonindependent success rates among bundle components. There was considerable enthusiasm among other practices and sectors to learn with us and to measure system performance using time-linked trajectories. We learned to present our data in ways that balanced aspirational long-term or multidisciplinary goal-setting with more easily attainable short-term aims. On the basis of our experience with the Thrive at 5 measure, we discuss future directions and place a broader call to action for pediatricians, researchers, policy makers, and communities.
Justiça restitutiva como procedimento de libertação da escravidão negra em Epifanio de Moirans
Authors: Decothé Jr. Joel Francisco
Published: December 2019

Este texto busca articular uma das aporias que marcaram a vida das sociedades coloniais da América espanhola, a saber, o tráfico e escravidão de pessoas negras trazidas do continente africano. Diante desta situação este estudo aborda uma das primeiras propostas teóricas antiescravagista, que foi propugnada pelo religioso capuchinho Epifanio de Moirans OFMCap (1644-1689). Sua obra Servi liberi seu naturalis mancipiorum libertatis iusta defensio foi concluída em 1682. Esta proposta versa, entre outras coisas, sobre os procedimentos justos de libertação da escravidão, mediante a restituição dos bens às pessoas que foram vítimas destas práticas injustas nas paragens coloniais. Para tanto, seguimos o itinerário de análise da provocativa inquirição encetada contra as mentalidades escravagistas. A exigência ética aqui é a da realização do imperativo de restituição dos bens às pessoas escravizadas. Isso objetivava o ato restaurativo do valor do seu trabalho escravo. Em seguida, buscamos reconstruir como poderia ser implementada a concepção de uma teoria da justiça restitutiva, que tinha de lidar com a tensão de contínua dubiedade na recepção injusta de pessoas no tráfico escravo. Por fim, tratamos da proposição contestatória do frade capuchinho francês, no sentido de se instituir um procedimento de restituição dos bens materiais como algo factível. Então, a meta era a do ressarcimento integral dos danos causados pela famigerada e injusta prática legal da escravidão negra no contexto ibero-americano colonial.

“Aos moldes da terra natal”: imigrantes sul-brasileiros no Paraguai
Authors: Gnoatto Vanucia
Published: December 2019

O presente artigo busca analisar a importância das redes sociais criadas entre as famílias  imigrantes sul brasileiros que adentraram no Paraguai entre as décadas de 1970 a 1980 na manutenção de aspectos identitários próprios em algumas cidades do departamento do Alto Paraná. Partindo da revisão historiográfica do tema, busca-se identificar quais elementos de composição de sua identidade étnica e regional foram mantidos, quais traços foram assimilados, dando origem a uma identidade híbrida e quais as resistências presentes. Parte-se do pressuposto de que é uma zona fronteiriça e, consequentemente, com identidades fluídas ou porosas. Mesmo nesse contexto, os imigrantes brasileiros diferenciavam-se em relação ao outro por meio da língua e de sua cultura original mantida através das redes culturais criadas, que preservam a relação destes muito próxima ao país de origem. Como fontes de estudo, recorreu-se à revisão historiográfica e de fontes orais.
Features of Calculating Kinematic and Roughness Parameters at Abrasive Finishing of Shut-Off Surfaces of Gate Valve Bodies Connecting Pipes
Authors: Skryabin Vladimir A.
Published: December 2019

Introduction. The author defines main provisions for peculiarities of the kinematics of plant lapping in the process of finishing shut-off elements of the valves, as well as methods for determination of operating parameters and values of roughness in the process of abrasive finishing of sealing surfaces of valves.
Materials and Methods. The kinematic scheme of grinding machines was developed to determine the angular velocity of rotation of an instrumental disc and lapping machine. Based on the developed kinematic scheme, we obtained analytical expressions to determine the capacity of the machine’s drive motor and cutting elements, as well as the angular and linear speeds of rotation of tool drive and laps. There were also developed trajectory traces of grid points of the lapping tool at its movement along with the treated surface details of pipe fittings.
Results. There are given examples of calculation of kinematic parameters and roughness of the treated sealing surface of gate valves with the diameter DN = 100 according to established analytical dependencies for rough and finish lapping. The coordinates of the moving tools were calculated with visualization of trajectory points using special software Lazarus. The coordinates were calculated and the trace of the moving point tool was built. The specific space which characterizes the capacity of the sealing surfaces was calculated.
Discussion and Conclusion. Calculations allowed us to determine how to place the lapping tool relative to the machine’s sealing surface for optimization of the treatment process. Preliminary calculations showed that the area of lapping tool’s contact with the workpiece and the optimum angle of contact would change slightly within the relative probability of error of 5% and 10%.
Study of Master Plans of Technical Service Enterprises in Agricultural Sector
Authors: Komarov Vladimir A. , Salmin Vladimir V. , Kurashkin Mikhail I.
Published: December 2019

Introduction. Most of the territories where technical service enterprises are located in the agricultural-and-industrial complex, are high-quality agricultural lands. However, so far no analysis of the technological feasibility of using these land plots has been made. The goal of this work is to develop recommendations for the effective use of areas allocated for technical service enterprises, taking into account the increase in the density of development of territories through reconstructing of repair and service bases.
Materials and Methods. Determination of actual indicators of the development density for technical service enterprises and their compliance with the set of rules was carried out using the companies’ accounting documents and situational plans for repair and maintenance bases. In the course of the study, recommendations were developed for reconstruction of master plans to increase the development for density repair and maintenance bases of these companies.
Results. The results of studies of the actual development density of technical service enterprises have shown that in 65% of cases it is below the minimum development density established by the code of rules SP 19.13330.2011. The actual density maintenance bases is in the range of 5.1–66.0%. At the same time, the actual average density of development of enterprises of technical service for agricultural producers was 19.7%. The largest number of enterprises (61.9%) has the development density of 5–20%, that is, significantly lower than the standard value. The smallest number of enterprises (3.6%) have the development density in terms ecology of above 50%. Most enterprises (58.5%) have the green area less than 10%, which is lower than the regulated value. This characterizes the sites under considering as not meeting modern requirements. Comparing the actual value of the utilization rate of the enterprises site and the minimum value of the utilization rate of agricultural enterprises, it was found that 62% of the repair and maintenance bases of technical service enterprises did not exceed the value recommended in the special literature.
Discussion and Conclusion. We showed the low efficiency in the use of areas allocated for repair and maintenance bases of technical service enterprises in various areas of the agricultural- and-industrial complex of the Volga Federal District of the Russian Federation.
Equilibrium Conditions of Agricultural Machines for Main Tillage
Authors: Bozhko Igor V. , Parkhomenko Galina G. , Kambulov Sergey I.
Published: December 2019

Introduction. The use of the equations of statistics and dynamics is insufficient to solve the problem of equilibrium of agricultural aggregates, and additional efforts are required that in turn significantly increases the complexity of relevant research. Known studies are characterized by the fact that when analyzing the stability of the tillage machine, on the basis of the equilibrium condition, a standard plow body is considered as a working body.
Materials and Methods. In this study, a variety of methods was used to determine equilibrium conditions for a system of converging forces in an analytical or geometric form. The equilibrium conditions were determined for the mounted five-case combined machine made soilless tillage. Analytical determination of the equilibrium conditions for the system was through the preparation of equilibrium equations. A graphical definition of the equilibrium conditions was obtained by constructing power polygons for vertical and horizontal projection planes.
Results. As a result, it was found that tillage machines have an excessive number of bonds (supports). There is defined a condition for the balance of forces acting on a tillage machine with working bodies for layer-by-layer subsurface tillage, having twelve connections: five field boards with two connections each and two support wheels one at a time, the perceivable responses from the interaction with which should be positive.
Discussion and Conclusion. According to the results, it is noteworthy that modern agricultural machines are multi-operation statically indeterminate systems. As a result, the process of their regulation during operation is complicated and it is practically impossible to make power calculations without accepting additional conditions. For simplification, accuracy and most visual representations, the problem was solved by analyzing closed force polygons, the construction method of which is presented for both the equilibrium conditions in horizontal and vertical planes.

The justification of parameters and introduction of new environmentally friendly technologies and technical means for weed control in the stalk zone is a pressing issue of major economic importance. The aim of the study is to justify the effective modes of operation trailer machine for the hydraulic removal weeds on the industrial plantation of horticultural crops.
Materials and Methods. According to the analysis of existing technologies and technical means for weed vegetation removal from the stalk zone of garden plantings, a device for hydraulic removal of weed vegetation without the use of herbicides has been developed at Federal Scientific Agroengineering Center VIM. To identify the most effective modes of operation of the machine on an industrial plantation of an apple orchard, a factorial experiment was conducted. Statistical processing of the obtained experimental results was carried out using mathematical modeling.
Results. The statistical analysis of the factor experiment data showed that the following operating modes of the device are the most effective for performing the technological operation of hydraulic removal weeds: the distance between the soil and the spray head is 14.5 cm, the working fluid supply pressure is 759 bar, the movement speed is 2.4 km/h. The static treatment mode for estimating the penetration depth of the jets with exposures of 10, 5, and 3 sec showed a penetration depth of 62, 34 and 12 mm, respectively. The diameters of the track were: In the first case 350 mm external and 330 mm internal (cutting width 24 mm); in the second and third cases – 340 mm for the outer and 328 mm for the inner (cutting width 16 mm).
Discussion and Conclusion. As a result of the experiment, it was established that the machine is able to provide high-quality processing stalk zone when using water from the central water supply. After the unit cultivated the soil, 90% which was covered with weeds, only 20–30% of the visible green mass remains, the rest is mixed with the soil. After doube cultivation, the root system of weed vegetation remained in 10–13% of the area. The device meets the requirements of the technological operation weed vegetation removal in the stalk zone without the use of herbicides with sufficiently high technological parameters.

According to it, the latter is estimated using the value of a complex criterion that includes a set of particular indicators and their relative importance.
Results. It is proposed to evaluate the efficiency of the broom corn harvesting process according to a complex criterion that takes into account particular indicators and their relative importance. A developed process for harvesting broom corn includes: threshing of standing broom corn in the direct flow offset threshing chamber of a combine harvester with simultaneous mowing of the threshed plants using the combine harvester thresher; collecting the threshed and mown plants in the tractor trailer and the threshed grain in the hopper; transportation of threshed and cut plants to the place of storage; and stacking of threshed plants with drying them using active ventilation. Based on experimental studies, the values of all the studied particular indicators and their coefficients of relative importance were determined; a comprehensive performance criterion for the existing process for broom corn harvesting and the proposed process was calculated.
Discussion and Conclusion. The calculated values of coefficients K* 1 and K* 2 for the existing and proposed processes for harvesting broom corn were used to determine the complex performance criterion, which is φ(Wi) = 15.54 for the existing process and φ(Wi) = 2588.75 for the proposed one respectively. According to the complex criterion, the proposed harvesting process is more efficient than that currently used more than 160 times.
The role of l-type calcium channels in the mediation of fast oscillation of arterial blood pressure and renal blood flow in rats
Authors: Markova P. , Girchev R.
Published: December 2019

The investigation of dynamic characteristics of blood pressure and renal blood flow provides detailed information about the fast regulatory mechanisms involved in arterial blood pressure (ABP) and renal blood flow (RBF) autoregulation. The aim of our study was to investigate the role of L-type Ca2+ channels in the mediation of fast oscillations of arterial blood pressure and renal blood flow in rats by means of spectral analysis. The experiments were performed on anesthetized male Wistar rats (n=7) at the age of 12-14 weeks. The ABP was measured directly in femoral artery; RBF was registered by perivascular ultrasonic Doppler probe (Transonic system) in control and experimental period. The spectrograms from APB and RBF were derived in Lab View 3.11 software. In experimental period the selective L-type Ca2+ channel blocker amlodipine besylate (AML) in dose 200 mkg.kg-1 bolus followed by 50 mkg.kg-1.h infusions was applied. Our results by using a spectral method of analysis of ABP and RBF confirmed involvement of L-type Ca2+ channels in the mediation of dynamic nature of myogenic vascular response. The L-type Ca2+ channels in different specific manner participate in the regulation of renal blood flow and arterial blood pressure.

Perfect Pell and Pell–Lucas numbers
Authors: Bravo Jhon J. , Luca Florian
Published: December 2019

The Pell sequence is given by the recurrence Pn = 2Pn−1 + Pn−2 with initial condition P0 = 0, P1 = 1 and its associated Pell-Lucas sequence is given by the same recurrence relation but with initial condition Q0 = 2, Q1 = 2. Here we show that 6 is the only perfect number appearing in these sequences. This paper continues a previous work that searched for perfect numbers in the Fibonacci and Lucas sequences.
Domain representable Lindelöf spaces are cofinally Polish
Authors: Tkachuk Vladimir V.
Published: December 2019

We prove that, for any cofinally Polish space X, every locally finite family of non-empty open subsets of X is countable. It is also established that Lindelöf domain representable spaces are cofinally Polish and domain representability coincides with subcompactness in the class of σ-compact spaces. It turns out that, for a topological group G whose space has the Lindelöf Σ-property, the space G is domain representable if and only if it is Čech-complete. Our results solve several published open questions.
Lemniscate convexity of generalized Bessel functions
Authors: Madaan Vibha , Kumar Ajay , Ravichandran V.
Published: December 2019

Sufficient conditions on associated parameters p, b and c are obtained so that the generalized and “normalized” Bessel function up(z) = up,b,c(z) satisfies the inequalities ∣(1 + (zu″p(z)/u′p(z)))2 − 1∣ < 1 or ∣((zup(z))′/up(z))2 − 1∣ < 1. We also determine the condition on these parameters so that . Relations between the parameters μ and p are obtained such that the normalized Lommel function of first kind hμ,p(z) satisfies the subordination . Moreover, the properties of Alexander transform of the function hμ,p(z) are discussed.
Stronger forms of sensitivity on product dynamical system via Furstenberg families
Authors: Thakur Rahul , Das Ruchi
Published: December 2019

In this paper, it has been investigated that how various stronger notions of sensitivity like 𝓕-sensitive, multi-𝓕-sensitive, (𝓕1, 𝓕2)-sensitive, etc., where 𝓕, 𝓕1, 𝓕2 are Furstenberg families, are carried over to countably infinite product of dynamical systems having these properties and vice versa. Similar results are also proved for induced hyperspaces.
The influence of context on ayahuasca experiences: An analysis of experience reports
Authors: Sapoznikow Avery , Walsh Zachary , Tupper Kenneth W. , Erowid Earth , Erowid Fire
Published: December 2019

Background and aims

Ayahuasca is a psychedelic decoction prepared from two (or more) plants containing monoamine oxidase inhibitors,N,N-dimethyltryptamine, and other chemicals. Ayahuasca has apparently been used for centuries in the Amazon basin of South America, and in recent years has increasingly been used internationally in diverse contexts. This study aims to elucidate differences betweencross-cultural ceremonialandpsychonauticcontexts of ayahuasca use.

Methods

This study systematically examines subjective differences across contexts for contemporary ayahuasca-drinking practices. User reports of ayahuasca experiences were subjected to textual analysis to compare use incross-culturalceremonialcontexts that attempt to include elements of traditional Amazonian practices, withpsychonauticuse that does not formally integrate traditional ceremonial aspects. The experience reports were collected from an online database.

Results

The use of ayahuasca in a cross-cultural ceremonial context is associated with prominence of affective and motivational features, whereas psychonautic use was associated with an emphasis on cognitive processes.

Conclusions

The beneficial effects of ayahuasca may operate via affective processing and integration and as such,cross-cultural ceremonialuse may have advantages relative topsychonauticuse. Findings are considered in light of the importance of context on experiences with ayahuasca and other psychedelic substances.
Exploring adherence and attitude towards the Mediterranean diet in a Spanish population
Authors: Posta A
Published: December 2019

Purpose

The traditional Mediterranean diet (MD) is recognized worldwide as one of the healthiest existing dietary patterns. However, over the past few decades, a significant deviance from this diet has been observed in a number of Mediterranean countries. The purpose of this study was to assess the Spanish population’s degree of deviance from the MD and to explore the possible causes.

Materials and methods

A survey was completed by a total of 126 Spanish citizens over the age of 18 years. Dietary and lifestyle habits were assessed using MEDLIFE, a validated index, which was complemented with a questionnaire developed for this study, as well as a 24-hour recall.

Results

The mean MEDLIFE score of 15 ± 3.07 revealed the average adherence to the MD, while the maximum score was 28. This study showed no significant positive correlation between MEDLIFE scores and age. The mean ratio of macronutrient intake was 20%E protein, 47%E carbohydrates, and 33%E fat.

Conclusions

The results of the study indicate a deviation from several components of the MD. Low MD adherence could be associated with insufficient knowledge regarding the exact composition and health effects of the MD.
De Falla's Hungarian Success: A háromszögletű kalap (1928)
Authors: Giménez-Rodríguez Francisco J.
Published: December 2019

In this study, I examine a hitherto completely unknown subject: the Hungarian reception of Manuel de Falla's ballet pantomime, El sombrero de tres picos (The three-cornered hat). As I point out, the story of the piece began well before Falla composed his music: Alarcón's novel was published in a Hungarian translation just two decades after the Spanish original. In the first decades of the twentieth century, the Budapest Opera House (Magyar Állami Operaház) and Municipal Theatre (Városi Színház) developed intensive opera, theatre, and ballet seasons, in association with the main European capitals during the first decades of the twentieth century. De Falla's ballet was premiered in Budapest in 1927 by Diaghilev's Russian Ballet, in the Municipal Theatre under the Hungarian title A háromszögletű kalap. The piece had such success that it had to be repeated three times. What is more, a Hungarian production was premiered in the Budapest Opera House one year later and this production continued until 1963, delivering a total of 75 performances. The sources (among others the handwritten performing scores) of this latter production preserved in the National Széchényi Library and in the Archives of the Hungarian State Opera House reveal an intense work of choreographic adaptation, along with careful design of staging, costumes, lightning, and scenery effects, all accomplished by great international personalities to make this very Spanish ballet understandable to the Magyar audience. Falla's work also found a significant support in the press, highlighting both the plot's universality and the expressiveness of his music, which had made it a Hungarian success.
