Личное — это профессиональное: этичность молодых крафтовых предпринимателей в Санкт-Петербурге
Authors: Ариф Эльвира Маратовна , Кузьминова Тамара Александровна
Published: July 2021

Цель статьи — выявить и описать элементы профессиональной этики молодых этичных крафтовых предпринимателей. Внимание фокусируется на специфике малого крафтового бизнеса и ведущей роли его владельца, подчеркивается значимость просьюмеристской позиции молодых предпринимателей. Также рассмотрены особенности креативного предпринимательства как стиля жизни.
Эмпирическую базу составили результаты двух исследований. В первом анализируются три кейса этичных крафтеров из Санкт-Петербурга: владелицы кофейни, арт-дизайнера и дизайнера льняной одежды. Во втором исследовании на примере анализа сообщений в телеграм-каналах рассматриваются риторические основания экологического дискурса. В статье показано, что в среде крафтовых предпринимателей определяющей становится личность владельца. Критичная позиция по отношению к перепотреблению приводит молодых предпринимателей к представлению о том, что быть этичным значит быть экологичным. Ориентация в первую очередь на доход не позволяет отнести бизнес информантов к социальному предпринимательству. Информанты не называют свои проекты эконаправленными, вместе с тем для них важна социальная составляющая предпринимательской деятельности и включение в свой проект экологичных практик. Информанты проблематизируют потребление через риторику неразумности, утраты, наделения вещи правом.
Выявлены три элемента профессиональной этики экологичных крафтовых предпринимателей: открытость для взаимодействия с другими предпринимателями, реализация социальных активностей, создание сообщества вокруг бизнес-проекта. В условиях становления этичного крафтового предпринимательства его отличительной чертой можно назвать открытость — и для взаимодействия, и для включения в разные дискурсы.

Published: July 2021

В статье приводится анализ портретных характеристик регионального молодежного волонтерского сообщества, осуществляющего деятельность в период пандемии COVID-19, определяются особенности ее организации и реализации в условиях риска и неопределенности. Эмпирическое исследование проведено методом анкетирования молодежи Свердловской области от 14 до 24 лет в период с 15 августа по 15 октября 2020 г., N = 1105, тип выборки — квотная, ошибка не более 3,5%. В ходе статистического анализа реализованы процедуры бинарной логистической регрессии с целью оценки вклада факторов (социально-демографических, деятельностных, информационных, самоидентификационных и пр.) в участие добровольцев в акции #МыВместе. На результатах исследования показано, что героями сложного времени стали представители малочисленной просоциально настроенной и политически ориентированной части российской молодежи, ранее включенной в организационные структуры, создаваемые в рамках государственной молодежной политики. Исключенным оказалось молодежное большинство. Гипотеза о расширении социальной базы молодежного волонтерства в период пандемии за счет ресурсов интернет-коммуникации не получила эмпирического подтверждения. Была подтверждена дееспособность инфраструктуры волонтерства в решении социальных проблем в кризисный период только в отношении уже организованной молодежи региона. Ее информационные ресурсы оказались действенными исключительно для опытных, активно участвующих в организованной общественной деятельности молодых добровольцев. Показано, что для ядра организованного волонтерского движения молодежи характерны гибридные модели волонтерства, сочетающие элементы традиционной, советской и демократической модели.

Материнство и университет: стратегии баланса жизни и работы
Authors: Таракановская Ксения Сергеевна
Published: July 2021

В статье представлены результаты исследования баланса жизни и работы преподавательниц и исследовательниц, имеющих несовершеннолетних детей. Анализ базируется на качественном исследовании, проведенном в 2020 г. методом полуструктурированных интервью в очном и дистанционном (с помощью программы Zoom) форматах. Определены смысловые компоненты понимания баланса, изучены субъекты поддержки, описаны схемы согласованности материнства и задач академического труда. Традиционно стратегия «работающей матери» в академических кругах обретает форму лимитирования карьерных амбиций, выбора преподавательского трека. Помимо этой стратегии были обнаружены следующие: «первенство материнства», «отложенное материнство», «спланированное материнство», «выжидательное материнство», «выстраивание границ между работой и личной жизнью», «перетекание границ работы и личной жизни», «минимизация рисков потери квалификации», «оптимизация условий труда», «распределение/делегирование обязанностей», «наставничество».
Стратегии баланса жизни и работы имеют личностную природу (необходимость выстраивания приоритетов, жесткого тайминга, снижения требований соответствия идеалу), но одновременно отражают внешние возможности поддержки, такие как помощь близких, использование декрета с учетом индивидуальных потребностей, аутсорсинг некоторых видов деятельности, наставничество. Гибкий режим труда оценивается неоднозначно: зачастую он воспринимается как барьер к продуктивной работе.

The outcome in terms of pressure from the dynamic simulation of the designed compensator with pump has been compare with experimental result obtained from a reference commercial pump has compensator with duel spool. The model has been used for performance prediction for wide variations of the load valve area settings.
A comparison of the performance of entropy measures for interval- valued intuitionistic fuzzy sets
Authors: KOKOÇ Melda
Published: July 2021

Entropy measure is a significant tool to define unclear information. But, entropy measures for interval-valued intuitionistic fuzzy sets (IVIFSs) cannot be easily understood intuitively. So, it is highly important to compare the existing measures to select a reliable entropy measure in studies. The purpose of this study is to compare the performance of different entropy mea- sures developed for IVIFSs. The numerical examples are presented to show whether entropy measures for IVIFSs are effective in representing the fuzziness degree. In order to understand whether a variation of fuzziness degree of one or more elements of IVIFSs change the ranking results, selected IVIFSs are modified diversely.
Solar radiation forecasting by using deep neural networks in Eski̇şehi̇r
Authors: QASEM Mohammed
Published: July 2021

According to the World Economic Outlook (WEO), the global demand for energy is presum- ably going to be increased due to growing the world’s population up during the upcoming two decades. As a result of that, apprehensions about environmental effects, which appear as a re- sult of greenhouse gases are grown and cleaner energy technologies are developed. This clearly shows that extended growth of the worldwide market share of clean energy. Solar energy is considered as one of the fundamental types of renewable energy. For this reason, the need for a predictive model that effectively observes solar energy conversion with high performance becomes urgent. In this paper, classic empirical, artificial neural network (ANN), deep neural network (DNN), and time series models are applied, and their results are compared to each other to find the most accurate model for daily global solar radiation (DGSR) estimation. In addition, four regression models have been developed and applied for DGSR estimation. The obtained results are evaluated and compared by the root mean square error (RMSE), rela- tive root mean square error (rRMSE), mean absolute error (MAE), mean bias error (MBE), t-statistic, and coefficient of determination (R2). Finally, simulation results provided that the best result is found by the DNN model.
Analysis of some conserved miRNAs in hazelnut (Corylus avellena L. and Corylus colurna L.) by real-time PCR
Authors: YİRMİBEŞ Büşra
Published: July 2021

Hazelnut is an important plant species which is used in food industry, dye industry, wood- chopping and stock farming and it has also benefits for health due to nutrient component. Eco- nomically valuable Corylus avellena and Corylus colurna used as rootstock are the most com- mon cultivars. Although many studies have been made about microRNA in plants so far, there are few studies in hazelnut. miRNAs are 18–25 nucleotide, short and single strand non-coding RNAs. miRNAs called as post-transcriptional gene regulators cause repress or cleavage of their target mRNA. In particularly in plants, they cause cleavage of mRNA and so play role in devel- opmental process, response process to biotic and abiotic stresses like drought, salt, cold or UV. Conserved miRNAs are miRNAs which have same function in different plant species and are conserved from very old times to the present. In this study, we aimed that analyzing of some conserved miRNAs (miR159, miR160, miR171, miR396, miR2919 and miR8123) in hazelnut (Corylus avellena L. and Corylus colurna L.) by Real-Time PCR. We found which these con- served miRNAs are present in both hazelnut species.
Using systematic review and meta-analysis in order to obtain different empirical-informative prior for bayesian binomial proportion
Authors: AVCI Esin
Published: July 2021

The Bayesian approach provides a direct and useful inference about parameters better so than the frequentist (likelihood-only based) approach. This is because Bayesian approach uses both sources of information: prior information and likelihood. The eliciting of prior information is important because of a visible impact on the posterior inference. The motivation of this study is to avoid the subjectivity in obtaining informative prior. In order to elicit informative priors, this study proposed using systematic reviews, and the meta-analysis which is a statistical syn- thesis of the results from a series of empirical studies. Even though the systematic review and meta-analysis may include publication bias, may give more objective information from expert opinion due to the publishing process. This study also aimed to present the impact of domes- tic information obtained from domestic systematic reviews and meta-analysis on estimation proportion. Systematic reviews and meta-analysis of proportion used in order to obtain dis- crete, histogram, and conjugate (Beta) informative priors. The effectiveness of the Bayesian inference of proposed different informative prior distributions compared within and between (all-domestic) prior distribution. The results revealed that the discrete and histogram priors were more effective than the conjugate and non-informative priors. On the other hand, the importance of using systematic reviews and meta-analysis for domestic studies was observed.
Analogy as driving force of language change: a usage-based approach towoanddaclauses in 17th and 18th century German
Authors: Gillmann Melitta
Published: July 2021

This paper presents a case study conducted on 17th and 18th century German corpora, confirming that both attraction and differentiation are important mechanisms of change, which interact with socio-symbolic properties of constructions. The paper looks at the frequencies and semantics ofwo‘where’ clauses at the beginning of the New High German period, which are compared to the frequencies and semantics of the connectorda‘there, since’ in the same period. The study reveals that the subordinating connectorswoanddaoverlapped in their functions and were highly polysemous (or semantically vague), establishing spatial, temporal, causal, conditional, and contrast links between clauses. This suggests that the connectors had become functionally similar by means of mutual attraction; however, they differed in that they belonged to different registers. Over the course of the 18th century, the polysemy ofwoanddaclauses reduced. Being gradually confined to one single meaning, the connectors became less similar. This differentiation occurs because the connectors aligned to distinct high-level schemas in the associative network. The study confirms that analogy is crucial to both attraction and differentiation of functionally overlapping constructions. While attraction involves analogy of specific instances of constructions, differentiation occurs in analogy to high-level abstract constructions in the associative network.
Capturing Transnational Entrepreneurial Opportunities through Dual Identification: Immigrant Entrepreneurs and Transnational Activities
Authors: Abd Hamid Hamizah , Ayob Abu Hanifah , Sidek Farhana , Che Senik Zizah
Published: July 2021

The purpose of this paper is to explore the way immigrant entrepreneurs (IEs) capture transnational opportunities in their home and host countries. Through an identity lens, this study adopts a qualitative approach in examining transnational entrepreneurship activities conducted by IEs from three countries (Indonesia, Pakistan and South Korea [henceforth Korea]) in one host country (Malaysia). The findings indicate that IEs’ home-host country identities enable them to recognize and exploit entrepreneurial opportunities in multiple countries through unique resources difficult to be imitated by competitors in their home and host countries. This paper contributes to the international entrepreneurship literature by introducing an identity-sensitive model of immigrant entrepreneurship in transnational spaces which will be useful for policy and practice concerning trade and migration.
The influence of membrane electrode assembly’s pressing on PEM fuel cell’s performance
Authors: Perdomo Federico , Abboud Matilde , Teliz Erika , Zinola Fernando , Díaz Verónica
Published: July 2021

The performance of a fuel cell depends on multiple factors, one of the most important being the preparation of the membrane electrode assembly (MEA). In the present work, MEAs constituted by gas diffuser electrodes (GDE) were pressed with carbon supported platinum catalysts. As solid electrolyte, a commercial polymeric membrane from Nafion was used, which was pressed at two GDE with loads of 5 and 1.5 mg/cm2 of catalyst at different temperatures and pressures for a fixed period of time. The assembly was characterized electrochemically using linear sweep voltammetry and electrochemical impedance spectroscopy at three different potentials. Also, the behavior when reversing the supply of hydrogen and oxygen to the GDE was studied. The results of the study showed a great dependence of the charge transfer resistance with the temperature, being secondary the dependence with the pressure in the range of temperature and pressure analyzed. Likewise, changes were observed in the open circuit potential after varying the temperature, pressure and catalyst load, hence affecting its maximum power and efficiency at that point.
In Situ Visualization for Control of Nano-Fibrillation Based on Spunbond Processing Using a Polypropylene/Polyethylene Terephthalate System
Authors: Md. Shahin A. N. , Shaayegan V. , Lee P. C. , Park C. B.
Published: July 2021

In situ generation of polyethylene terephthalate (PET) nanofibrils in polypropylene (PP) microfibers via fiber spinning in a spunbond process was studied in this work. The effects of polymer flow rate and air speed in the drafter on the formation of PET fibrils were investigated using a pilot scale machine. An in-situ visualization technique was applied to examine the fiber evolution events and stretch profile at die exit. A scanning electron microscope was used to analyze and investigate the morphology of the dispersed domain. The PET dispersed phase was fibrillated within the PP matrix such that a nonofibrillated composite containing fibrils with an average size around 100 nm was obtained. It was found that the final fibril size directly depends on the degree of die swell, the air speed and the polymer flow rate. It was also found that the in situ observed size of the micro-scale PP/PET fibers was well correlated to the size of the nano-scale PET fibers formed in the PP matrix. The visualization results revealed that a smaller fibril diameter was obtainable by increasing the stretching on the spin line and/or decreasing the die swell.
Magnetic plasmons induced in a dielectric-metal heterostructure by optical magnetism
Authors: Li Shulei , Zhou Lidan , Panmai Mingcheng , Xiang Jin , Lan Sheng
Published: July 2021

We investigate numerically and experimentally the optical properties of the transverse electric (TE) waves supported by a dielectric-metal heterostructure. They are considered as the counterparts of the surface plasmon polaritons (i.e., the transverse magnetic (TM) waves) which have been extensively studied in the last several decades. We show that TE waves with resonant wavelengths in the visible light spectrum can be excited in a dielectric-metal heterostructure when the optical thickness of the dielectric layer exceeds a critical value. We reveal that the electric and magnetic field distributions for the TE waves are spatially separated, leading to higher quality factors or narrow linewidths as compared with the TM waves. We calculate the thickness, refractive index and incidence angle dispersion relations for the TE waves supported by a dielectric-metal heterostructure. In experiments, we observe optical resonances with linewidths as narrow as ∼10 nm in the reflection or scattering spectra of the TE waves excited in a Si3N4/Ag heterostructure. Finally, we demonstrate the applications of the lowest-order TE wave excited in a Si3N4/Ag heterostructure in optical display with good chromaticity and optical sensing with high sensitivity.

The blood-brain barrier (BBB) has a significant contribution to the protection of the central nervous system (CNS). However, it also limits the brain drug delivery and thereby complicates the treatment of CNS diseases. The development of safe methods for an effective delivery of medications and nanocarriers to the brain can be a revolutionary step in the overcoming this limitation. Here, we report the unique properties of the lymphatic system to deliver tracers and liposomes to the brain meninges, brain tissues, and glioma in rats. Using a quantum-dot-based 1267 nm laser (for photosensitizer-free generation of singlet oxygen), we clearly demonstrate photostimulation of lymphatic delivery of liposomes to glioma as well as lymphatic clearance of liposomes from the brain. These pilot findings open promising perspectives for photomodulation of lymphatic delivery of drugs and nanocarriers to the brain pathology bypassing the BBB. The lymphatic “smart” delivery of liposomes with antitumor drugs in the new brain tumor branches might be a breakthrough strategy for the therapy of gliomas.

Plädoyer für einen (berufs-) alltagstauglichen Begriff von Spiritualität
Authors: Weiher Erhard
Published: July 2021

Ein Blick auf die deutschsprachige Diskussion um Spiritual Care zeigt:

Die Konzepte sind noch rar, die Grundlagen und Methoden spiritueller Kommunikation im Berufsalltag darstellen und entfalten. Dabei betonen so gut wie alle Stellungnahmen der Gesundheitsfachberufe die Wichtigkeit der Spiritualität in ihrer Arbeit.

Der folgende Beitrag lenkt den Blick von der Metaebene der Diskussion um Spiritualität auf die Mikroebene der konkreten Situationen, die die Angehörigen der versorgenden Berufe in Krankenhaus, Altenheim und Palliative Care antreffen. In diesem Beitrag wird ein Begriff von Spiritualität vorgestellt, der nicht nur der Hochform dieser Dimension, sondern auch der im Berufsalltag viel öfter indirekt begegnenden Form Rechnung trägt. Zudem findet man in der Literatur die konkrete Ausgestaltung von Spiritual Care oft nur umrisshaft und rudimentär dargestellt. Es braucht daher sowohl Verstehens- wie Anwendungskonzepte, die für die alltägliche Begegnungspraxis der Gesundheitsfachberufe hilfreich sind. Insofern versteht sich der hier vorgelegte Begriff von Spiritualität und der damit verbundene Ansatz der „symbolischen Kommunikation“ als Beitrag zum aktuellen Spiritual-Care-Diskurs.
Deciphering Spinal Endogenous Dopaminergic Mechanisms That Modulate Micturition Reflexes in Rats with Spinal Cord Injury

Published: July 2021

Spinal neuronal mechanisms regulate recovered involuntary micturition after spinal cord injury (SCI). It was recently discovered that dopamine (DA) is synthesized in the rat injured spinal cord and is involved in lower urinary tract (LUT) activity. To fully understand the role of spinal DAergic machinery in micturition, we examined urodynamic responses in female rats during pharmacological modulation of the DA pathway. Three to four weeks after complete thoracic SCI, the DA precursor L-DOPA administered intravenously during bladder cystometrogram (CMG) and external urethral sphincter (EUS) electromyography (EMG) reduced bladder overactivity and increased the duration of EUS bursting, leading to remarkably improved voiding efficiency. Apomorphine (APO), a non-selective DA receptor (DR) agonist, or quinpirole, a selective DR2agonist, induced similar responses, whereas a specific DR2antagonist remoxipride alone had only minimal effects. Meanwhile, administration of SCH 23390, a DR1antagonist, reduced voiding efficiency by increasing tonic EUS activity and shortening the EUS bursting period. Unexpectedly, SKF 38393, a selective DR1agonist, increased EUS tonic activity, implying a complicated role of DR1in LUT function. In metabolic cage assays, subcutaneous administration of quinpirole decreased spontaneous voiding frequency and increased voiding volume; L-DOPA and APO were inactive possibly because of slow entry into the CNS. Collectively, tonically active DR1in SCI rats inhibit urine storage and enhance voiding by differentially modulating EUS tonic and bursting patterns, respectively, while pharmacologic activation of DR2, which are normally silent, improves voiding by enhancing EUS bursting. Thus, enhancing DA signaling achieves better detrusor-sphincter coordination to facilitate micturition function in SCI rats.

Ayrıca çalışmalarda chiada bulunan flavonoidlerin ve tokoferolün tohumun antioksidan kapasitesinden sorumlu temel yapılar olduğu da tespit edilmiştir. Chia tohumlarının ve ekstraktının antioksidan kapasitesi üzerine yapılmış olan çalışmalarda lipit peroksidasyonunu engellediği, oksidatif strese karşı hücreyi koruduğu bulunmuştur. Bu derleme çalışmasında günümüzde kullanım alanı giderek genişleyen chia tohumunun antimikrobiyel ve antioksidan özelliklerinin derlenmesi ile fonksiyonel gıda üretimine katkısının değerlendirilmesi amaçlanmıştır.
Time-efficient approach to drill condition monitoring based on images of holes drilled in melamine faced chipboard
Authors: Jegorowa Albina , Antoniuk Izabella , Kurek Jarosław , Bukowski Michał , Dołowa Wioleta , Czarniak Paweł
Published: July 2021

This paper presents a time-efficient approach to the drill wear classification problem that achieves a similar accuracy rate compared to more complex and time-consuming solutions. A total of three classes representing drill state are recognized: red for poor state, yellow for elements requiring additional evaluation, and green for good state. Images of holes drilled in melamine faced chipboard were used as input data, focusing on evaluating differences in image color values to determine the overall drill state. It is especially important that there are as few mistakes as possible between the red and green class, as these generate the highest loss for the manufacturer. In green samples presented in gray-scale, most pixels were either black (representing the hole) or white (representing the chipboard), with very few values in between. The current method was based on the assumption that the number of pixels with intermediate values, instead of extreme ones, would be significantly higher for the red class. The presented initial approach was easy to implement, generated results quickly, and achieved a similar accuracy compared to more complex solutions based on convolutional neural networks.

Authors: Aziz Zoriah , Jet Chong Nyuk , Abdul Rahman Sameerah Shaikh
Published: July 2021

Continuing professional development (CPD) is a lifelong learning approach to maintain and enhance professional competencies. This cross-sectional study aimed to examine the pharmacists’ preferred CPD activities and barriers to CPD participation. A survey instrument was distributed to all government pharmacists (N=3876) in Malaysia. The response rate was 29.2 %. The majority of the pharmacists (92%) believed that engaging in CPD would improve their performances in their current role. Almost 90% of the respondents preferred to participate in CPD activities associated with continuing education such as workshops and conferences attendance. Barriers to CPD participation were current job constraints, lack of time, and accessibility in terms of travel and cost. It is important to address these issues before the implementation of mandatory CPD for pharmacists in Malaysia.

У результаті електронно-мікроскопічного (з енергодисперсійним) аналізу порід нафтогазоносних комплексів глибокого залягання встановлена присутність у вторинних порах (кавернах) і (мікро)тріщинах різноманітних за морфологією самородно-свинцевих агрегатних частинок. Виділяються їх гранулярні (натічно- коломорфні), пластинчаті і мікроін’єкційні морфологічні типи. Як й інші самородні метали (в геохімічній асоціації з Pb відзначені Zn, Sn, Cd, Sb та ін.), частинки Pb можуть розглядатися як трасери (супер)глибинних відновлених флюїдів. Завдяки ж високій пластичності свинцю його різні морфологічні типи можуть відігравати роль індикаторів розподілу мікростресових напруг у породах-колекторах нафти і газу глибокого залягання.
Influence of bisoprolol and nebivolol on the spectrum of substituted amino acids in blood plasma of patients with stable angina
Authors: Bogdan T.V.
Published: July 2021

For many years, ß-blockers have been used to treat patients with coronary heart disease. In patients with stable angina, the effect of ß-blockers on the amino acid spectrum of blood serum has been studied. Its violation is considered as one of the pathogenetic links in the development of atherosclerosis. The study showed a more efficient action of nebivolol compared to bisoprolol on the amino acid imbalance. In patients with stable angina against the background of antianginal therapy, which included bisoprolol and nebivolol, there was a significant decrease in the total amount of amino acids, the amount of essential amino acids, and the amount of essential amino acids compared to the treatment. Against the background of the nebivolol treatment, there is a positive dynamics of sulfur-containing amino acids (methionine level was maintained, taurine level was significantly increased, cystine level was normalized), isoleucine level was normalized, which indirectly indicates cardioprotective and angiprotective effect of nebivolol.
Muros visibles e invisibles. La migración en las relaciones entre Estados Unidos y América Latina
Authors: Rojas Diana Marcela
Published: July 2021

La migración ha sido un asunto central en las relaciones de Estados Unidos con América Latina. A lo largo de las dos últimas décadas, los flujos migratorios hacia el norte se han transformado, cuantitativa y cualitativamente, dando lugar a un fenómeno complejo y diferenciado. El endurecimiento de la política de la administración de Donald Trump en este campo hizo aún más difícil la respuesta a los desafíos que la migración plantea tanto para la propia política doméstica estadounidense y de algunos países latinoamericanos, como para los vínculos interregionales. El artículo analiza la posición de esa administración a la luz de lo que denominamos la “política del muro”, compuesta de muros físicos y externos, y muros simbólicos e internos. Para ello, se presenta un panorama de la migración latinoamericana hacia Estados Unidos, se examinan las principales decisiones del gobierno Trump, y se establece su impacto en las relaciones hemisféricas.
Respuesta institucional a la participación ciudadana contra el extractivismo en Colombia: la dimensión discursiva de una problemática asociada al cambio climático

Published: July 2021

Este artículo explora la respuesta pública a la participación ciudadana en contra del extractivismo en Colombia, teniendo en cuenta la contribución de la industria extractiva al cambio climático. Desarrollamos un Análisis Crítico del Discurso de las afirmaciones políticas contenidas en la Sentencia SU095/18 de la Corte Constitucional colombiana, utilizando un marco teórico crítico para fundamentar el análisis. Nuestros hallazgos exponen la manera en la que una instancia de participación ciudadana, la consulta popular, es privada de sus efectos en favor de un modelo extractivista de desarrollo. Bajo su apariencia de neutralidad, el discurso jurídico transporta contenidos ideológicos a favor de un modelo de desarrollo que contribuye significativamente al cambio climático y al establecimiento de una razón gubernamental que restringe la democracia y la deliberación pública acerca del ambiente, el desarrollo y el territorio.

Para ello nos preguntamos cómo fue el desempeño del Estado en la gestión del conflicto, y cómo él influyó en la evolución del conflicto en un país que registra más de 8600 pasivos ambientales mineros. Entre los principales hallazgos se encuentran: deficiencias en la capacidad de gestión estatal; desarticulación y centralismo del gobierno; pérdida de imparcialidad; Estado ausente; falta de capacidades legales y administrativas; pérdida de capacidad para canalizar demandas de la población; Pérdida de capacidad técnica para evaluar proyectos mineros; gestión deficiente de la fuerza policial bajo un enfoque de criminalización de la protesta.
Venezuela: un régimen militar sin capacidad de gobierno ni opción de transición política
Authors: Patiño Villa Carlos Alberto , Almario García Oscar
Published: July 2021

La crisis actual de Venezuela y las repercusiones para los países vecinos tiene un trasfondo que puede explicarse a través de los orígenes que dieron cabida al régimen, el contexto histórico en el que surge y el ensamblado institucional y militar que desarrolló para prolongarse en el poder del Estado. Esta situación ha contribuido a la dificultad de una transición política dada la inflexibilidad de la estructura del régimen, así como las importantes alianzas geopolíticas que han permitido su mantenimiento. En este sentido, se busca explicar la paradoja de cómo la construcción de un régimen instaurado principalmente sobre el ámbito militar como eje central, pero manteniendo las bases bolivarianas en los asuntos de la democracia formal, sumado a una anodina oposición venezolana, han permitido su permanencia en el poder a pesar de llevarlo a una crisis política caracterizada por la precaria capacidad de gobierno, la violencia colectiva y la pérdida parcial del reconocimiento internacional.
Constitución de 1991 y multiculturalismo a prueba de la experiencia: entre la institucionalización y la resistencia, los pueblos indígenas “llegaron para quedarse”
Authors: Laurent Virginie
Published: July 2021

El reconocimiento del carácter pluriétnico y multicultural de la nación colombiana corresponde a uno de los cambios más significativos introducidos por la Constitución de 1991, desde los planos societal y político. Con base en la experiencia de los pueblos indígenas, este artículo analiza los efectos de dicha transformación, entre discursos y prácticas. Ya pasados 30 años de la promulgación de la Carta Magna, en un contexto que atestigua un balance matizado para el “multiculturalismo a la colombiana”, se destaca su peso en el ámbito político (sub)nacional, entre la institucionalización y procesos de resistencia.
¿Del renacer al declive? Pugna sociocultural en la Bolivia contemporánea
Authors: Rey Cadavid Shannon
Published: July 2021

Tras la renuncia del presidente indígena de Bolivia, Evo Morales, quien se caracterizaba por un discurso decolonial, el presente texto ofrece una reflexión sobre la importancia de la comunicación visual y la indumentaria, particularmente en campos como la moda y la industria cultural. Para ello, se utilizan herramientas del análisis crítico del discurso y se exponen las transformaciones ocurridas en Bolivia durante los gobiernos de Morales, donde se abrió la puerta a un nuevo expresar sociocultural, en el que la cultura indígena renació hasta convertirse en un ejemplo de resistencia latinoamericana en contra de la colonización. Tal renacimiento se encuentra en vilo ante los cambios políticos que, biblia en mano, amenazaron con marchitar los logros indígenas que florecieron durante el gobierno de Morales.
Relações de discurso e completude monológica: o impacto da restrição ritual sobre o estabelecimento das relações interativas
Authors: Cunha Gustavo Ximenes
Published: July 2021

Na abordagem genebrina para o estudo do discurso (Escola de Genebra), as pesquisas sobre as relações de discurso (ilocucionárias e interativas) e seus marcadores privilegiam o estudo de como o locutor, ao procurar alcançar a completude monológica, estabelece essas relações para produzir um segmento textual (intervenção) completo do ponto de vista informacional. No entanto, essas pesquisas não evidenciam em que medida as restrições rituais, ligadas à preservação das faces e dos territórios em jogo, influenciam o estabelecimento dessas mesmas relações. Por esse motivo, o presente trabalho apresenta uma proposta para o tratamento das relações interativas que considere o impacto das restrições rituais sobre a elaboração da intervenção. Realizando-se em duas etapas (análise das relações genéricas e análise das relações específicas), o procedimento proposto permite um estudo detalhado do papel das relações interativas na gestão de faces e territórios, o que foi atestado por meio da análise do excerto de uma peça teatral.
Dialectics of the Development of the Integrated Social Systems
Authors: Somkin Alexander A.
Published: July 2021

Introduction. The paper analyzes the specificity of the dialectical development of the integrated social systems of such a personality and society. The presence of positive (natural) contradictions is recognized as a necessary and creative factor in social practice. Under the influence of this type of contradiction, the old, outdated forms of social structure (individual components of the social system) are denied and transformed to new, more perfect ones occurs as a result of their successful resolution. Methods. In the analysis, the author relied on a system-holistic approach, traditional general philosophical methods: induction and deduction, theoretical analysis and synthesis, extrapolation, etc. Discussion. The social system as an integrated unity goes through a number of stages from inception, formation and maturity to the transition to a qualitatively new state. Accordingly, the process of the emergence and development of dialectical contradictions also has several stages: from insignificant differences between opposite sides at the beginning of the emergence of the system to their strengthening and exacerbation. The nature of the contradictions depends on the specifics of the opposing sides, as well as on the conditions in which their interaction unfolds. The determining factor here, in the opinion of the author, is the positive (natural) direction of social opposition, under the influence of which the essence of the contradictions themselves is formed. Conclusion. According to the dialectical approach, the source of social development is the unity and struggle of opposites within the social system. However, the presence of opposite sides is a necessary but insufficient condition for development. They create the preconditions for it, but do not act as its driving force. Only a change in one opposition relative to another creates alternative tension, giving rise to a dialectical contradiction. Therefore, the antagonistic or non-antagonistic character of the latter is due to the positive (natural) or negative character of the social opposition itself.

Concepciones sobre lo divino en Lisímaco Chavarría y Jorge Luis Borges: Del universo a lo multiverso
Authors: Arley Fonseca Mauricio
Published: July 2021

El artículo parte de un interés comparativo acerca de las concepciones de lo divino, con referencia a los autores Lisímaco Chavarría y Jorge Luis Borges, cuyos textos literarios convergen con ideas comunes, y una de ellas origina esta propuesta de trabajo: Dios como fuente de lo trascendente. Esto conduce a la necesaria reflexión teórica sobre lo multiverso, con las múltiples facetas de la existencia divina. La muestra de textos literarios está compuesta por poemas, cuentos y ensayos, los cuales serán analizados a partir de aportes teóricos hermenéuticos, teológicos y literarios. En el desarrollo se presentará a Dios con distintos rostros y manifestado a través de la naturaleza, lo femenino, el aleph…, y así llega a tan diversas mentes. Pero vale acotar que en los textos seleccionados predomina un Dios de la tradición judeo cristiana con algunas referencias a divinidades egipcias, mayas, incas y nórdicas.
Escritura y movimiento dancístico como vía de inscripción subjetiva en la adolescencia
Authors: Molina Ovares Andrea , Herrera González Damián
Published: July 2021

Este artículo consiste en una lectura psicoanalítica del proceso creativo y de las obras artísticas realizadas por un grupo de adolescentes del cantón de San Ramón en espacios de expresión de danza y literatura. Concluye que la creación artística posibilita a las personas adolescentes pensarse y elaborar un discurso propio, contribuyendo a la construcción subjetiva de forma individual y colectiva. Además, los discursos sobre la muerte, el suicidio y la tragedia hacen un llamado a dejar de tratar estos temas como un tabú.
Evaluación de cuatro genotipos de pepino tipo largo cultivados bajo ambiente protegido
Authors: Cruz-Coronado José , Monge P´érez José
Published: July 2021

El objetivo del estudio fue evaluar el rendimiento y la calidad de cuatro genotipos de pepino (Cucumis sativus L.) partenocárpico de tipo largo (Arioso, Cumlaude, Kalunga y Paisaje), cultivados bajo condiciones de invernadero en la Estación Experimental Agrícola Fabio Baudrit Moreno, en Alajuela, Costa Rica. El cultivo se manejó con fertirrigación en sustrato de fibra de coco y con poda a un tallo por planta. En cuanto a los datos, muestran una amplia variabilidad entre los genotipos en edad al inicio de floración (19 – 21 días después del trasplante-ddt), edad al inicio de cosecha (28 – 30 ddt), longitud del fruto (31,02 – 32,38 cm), diámetro del fruto (48,74 – 52,31 mm), número total de frutos por planta (16,60 – 26,92), peso del fruto (470,17 – 517,77 g), rendimiento comercial (14,47 – 23,53 kg/m2), rendimiento total (20,49 – 33,46 kg/m2) y porcentaje de sólidos solubles totales (3,01 – 3,64 °Brix). Los frutos de pepino de primera calidad mostraron mayor longitud y diámetro que los de segunda calidad y de rechazo. En términos generales, los frutos de primera y segunda calidad obtuvieron un mayor porcentaje de sólidos solubles totales que los de calidad de rechazo. El genotipo Cumlaude obtuvo el mayor rendimiento de primera calidad (12,61 kg/m2), por lo que se considera el mejor adaptado a las condiciones en las que se desarrolló la investigación; por el contrario, Arioso obtuvo el menor rendimiento comercial y total.
