Biosolid application is an effective strategy, alternative to synthetic chemicals, for enhancing plant growth and performance and improving soil properties. In previous research, biosolid application has shown promising results with respect to tomato resistance against Fusarium oxysporum f. sp. radicis-lycopersici (Forl). Herein, we aimed at elucidating the effect of biosolid application on the plant–microbiome response mechanisms for tomato resistance against Forl at a molecular level. More specifically, plant–microbiome interactions in the presence of biosolid application and the biocontrol mechanism against Forl in tomato were investigated. We examined whether biosolids application in vitro could act as an inhibitor of growth and sporulation of Forl. The effect of biosolid application on the biocontrol of Forl was investigated based on the enhanced plant resistance, measured as expression of pathogen-response genes, and pathogen suppression in the context of soil microbiome diversity, abundance, and predicted functions. The expression of the pathogen-response genes was variably induced in tomato plants in different time points between 12 and 72 h post inoculation in the biosolid-enriched treatments, in the presence or absence of pathogens, indicating activation of defense responses in the plant. This further suggests that biosolid application resulted in a successful priming of tomato plants inducing resistance mechanisms against Forl. Our results have also demonstrated that biosolid application alters microbial diversity and the predicted soil functioning, along with the relative abundance of specific phyla and classes, as a proxy for disease suppression. Overall, the use of biosolid as a sustainable soil amendment had positive effects not only on plant health and protection, but also on growth of non-pathogenic antagonistic microorganisms against Forl in the tomato rhizosphere and thus, on plant–soil microbiome interactions, toward biocontrol of Forl.

Published: December 2021

The optimization of lithium-ion (Li-ion) battery pack usage has become essential due to the increasing demand for Li-ion batteries. Since degradation in Li-ion batteries is inevitable, there has been some effort recently on research to maximize the utilization of Li-ion battery cells in the pack. Some promising concepts include reconfigurable battery packs and cell replacement to limit the negative impact of early-degraded cells on the entire pack. This paper used a simulation framework, based on a cell voltage model and a degradation model, to study the feasibility and benefits of the cell replacement concept. The simulation conducted in MATLAB involves generating and varying Li-ion cells in the packs stochastically and simulating the life of the cells as well as the packs until they reach their end-of-life stage. It was found that the cell replacement method can increase the total number of cycles of the battery packs, effectively prolonging the lifespan of the packs. It is also determined that this approach can be more economically beneficial than the current approach of simple pack replacement. For the cell replacement concept to be practical, two main design criteria should be satisfied including individual cell monitoring and easy accessibility to cells at failure stage.

The combination of plasmonic material and magnetic metal oxide nanoparticles is widely used in multifunctional nanosystems. Here we propose a method for the fabrication of a gold/cobalt ferrite nanocomposite for biomedical applications. The composite includes gold cores of ~10 nm in diameter coated with arginine, which are surrounded by small cobalt ferrite nanoparticles with diameters of ~5 nm covered with dihydrocaffeic acid. The structure and elemental composition, morphology and dimensions, magnetic and optical properties, and biocompatibility of new nanocomposite were studied. The magnetic properties of the composite are mostly determined by the superparamagnetic state of cobalt ferrite nanoparticles, and optical properties are influenced by the localized plasmon resonance in gold nanoparticles. The cytotoxicity of gold/cobalt ferrite nanocomposite was tested using T-lymphoblastic leukemia and peripheral blood mononuclear cells. Studied composite has selective citotoxic effect on cancerous cells while it has no cytotoxic effect on healtly cells. The results suggest that this material can be explored in the future for combined photothermal treatment and magnetic theranostic.
Multispectral Mid-Infrared Camera System for Accurate Stand-Off Temperature and Column Density Measurements on Flames
Authors: Meléndez Juan , Guarnizo Guillermo
Published: December 2021

Accurate measurement of temperature in flames is a challenging problem that has been successfully addressed by hyperspectral imaging. This technique is able to provide maps of not only temperature T (K) but also of column density Q (ppm·m) of the main chemical species. Industrial applications, however, require cheaper instrumentation and faster and simpler data analysis. In this work, the feasibility and performance of multispectral imaging for the retrieval of T and QCO2 in flames are studied. Both the hyperspectral and multispectral measurement methods are described and applied to a standard flame, with known T and QCO2, and to an ordinary Bunsen flame. Hyperspectral results, based on emission spectra with 0.5 cm−1 resolution, were found in previous works to be highly accurate, and are thus considered as the ground truth to compare with multispectral measurements of a mid-IR camera (3 to 5 μm) with a six interference filter wheel. Maps of T and Q obtained by both methods show that, for regions with T ≳1300 K, the average of relative errors in multispectral measurements is ∼5% for T (and can be reduced to ∼2.5% with a correction based on a linear regression) and ∼20% for Q. Results obtained with four filters are very similar; results with two filters are also similar for T but worse for Q.

Authors: Akiyama Ryoto , Noguchi Naoto , Kondo Ken , Tanaka Koji , Lee Bumsuk
Published: December 2021

The purpose of this study was to examine aging and bimanual effects on finger spatial stability during precision grip. Twenty-one older and 21 younger adults performed precision grip tasks consisting of a single task (grip and lift an object with the thumb and index finger) and a dual task (the grip-lifting task with one hand and a peg board task with the other hand). The center of pressure (COP) trajectory and the grip force were evaluated using a pressure sensor with a high spatial resolution. In the COP trajectory, the main effects of age for the thumb (F1,140 = 46.17, p < 0.01) and index finger (F1,140 = 22.14, p < 0.01) and task difficulty for the thumb (F1,140 = 6.47, p = 0.01) were significant based on ANCOVA. The COP trajectory was statistically decreased in the older adults. The COP trajectory was also decreased in the dual task, regardless of age. The results suggest the existence of a safety strategy to prioritize the spatial stability in the elderly group and in the dual task. This study provides new insights into the interpretation of the COP trajectory.
Radiometric Identification of Signals by Matched Whitening Transform
Authors: Mobasseri Bijan G. , Lulu Amro
Published: December 2021

Radiometric identification is the problem of attributing a signal to a specific source. In this work, a radiometric identification algorithm is developed using the whitening transformation. The approach stands out from the more established methods in that it works directly on the raw IQ data and hence is featureless. As such, the commonly used dimensionality reduction algorithms do not apply. The premise of the idea is that a data set is “most white” when projected on its own whitening matrix than on any other. In practice, transformed data are never strictly white since the training and the test data differ. The Förstner-Moonen measure that quantifies the similarity of covariance matrices is used to establish the degree of whiteness. The whitening transform that produces a data set with the minimum Förstner-Moonen distance to a white noise process is the source signal. The source is determined by the output of the mode function operated on the Majority Vote Classifier decisions. Using the Förstner-Moonen measure presents a different perspective compared to maximum likelihood and Euclidean distance metrics. The whitening transform is also contrasted with the more recent deep learning approaches that are still dependent on feature vectors with large dimensions and lengthy training phases. It is shown that the proposed method is simpler to implement, requires no features vectors, needs minimal training and because of its non-iterative structure is faster than existing approaches.

Published: December 2021

Objective: Handheld dynamometers are common tools for assessing/monitoring muscular strength and endurance. Health/fitness Bluetooth load sensors may provide a cost-effective alternative; however, research is needed to evaluate the validity and reliability of such devices. This study assessed the validity and reliability of two commercially available Bluetooth load sensors (Activ5 by Activbody and Progressor by Tindeq). Methods: Four tests were conducted on each device: stepped loading, stress relaxation, simulated exercise, and hysteresis. Each test type was repeated three times using the Instron ElectroPuls mechanical testing device (a gold-standard system). Test–retest reliability was assessed through intraclass correlations. Agreement with the gold standard was assessed with Pearson’s correlation, interclass correlation, and Lin’s concordance correlation. Results: The Activ5 and Progressor had excellent test–retest reliability across all four tests (ICC(3,1) ≥ 0.999, all p ≤ 0.001). Agreement with the gold standard was excellent for both the Activ5 (ρ ≥ 0.998, ICC(3,1) ≥ 0.971, ρc ≥ 0.971, all p’s ≤ 0.001) and Progressor (ρ ≥ 0.999, ICC(3,1) ≥ 0.999, ρc ≥ 0.999, all p’s ≤ 0.001). Measurement error increased for both devices as applied load increased. Conclusion: Excellent test–retest reliability was found, suggesting that both devices can be used in a clinical setting to measure patient progress over time; however, the Activ5 consistently had poorer agreement with the gold standard (particularly at higher loads).

Published: December 2021

Large interactive displays can provide suitable workspaces for learners to conduct collaborative learning tasks with visual information in co-located settings. In this research, we explored the use of these displays to support collaborative engagement and exploratory tasks with visual representations. Our investigation looked at the effect of four factors (number of virtual workspaces within the display, number of displays, position arrangement of the collaborators, and collaborative modes of interaction) on learners’ knowledge acquisition, engagement level, and task performance. To this end, a user study was conducted with 72 participants divided into 6 groups using an interactive tool developed to support the collaborative exploration of 3D visual structures. The results of this study showed that learners with one shared workspace and one single display can achieve better user performance and engagement levels. In addition, the back-to-back position with learners sharing their view and control of the workspaces was the most favorable. It also led to improved learning outcomes and engagement levels during the collaboration process.
Smart Pothole Detection Using Deep Learning Based on Dilated Convolution
Authors: Ahmed Khaled R.
Published: December 2021

Roads make a huge contribution to the economy and act as a platform for transportation. Potholes in roads are one of the major concerns in transportation infrastructure. A lot of research has proposed using computer vision techniques to automate pothole detection that include a wide range of image processing and object detection algorithms. There is a need to automate the pothole detection process with adequate accuracy and speed and implement the process easily and with low setup cost. In this paper, we have developed efficient deep learning convolution neural networks (CNNs) to detect potholes in real-time with adequate accuracy. To reduce the computational cost and improve the training results, this paper proposes a modified VGG16 (MVGG16) network by removing some convolution layers and using different dilation rates. Moreover, this paper uses the MVGG16 as a backbone network for the Faster R-CNN. In addition, this work compares the performance of YOLOv5 (Large (Yl), Medium (Ym), and Small (Ys)) models with ResNet101 backbone and Faster R-CNN with ResNet50(FPN), VGG16, MobileNetV2, InceptionV3, and MVGG16 backbones. The experimental results show that the Ys model is more applicable for real-time pothole detection because of its speed. In addition, using the MVGG16 network as the backbone of the Faster R-CNN provides better mean precision and shorter inference time than using VGG16, InceptionV3, or MobilNetV2 backbones. The proposed MVGG16 succeeds in balancing the pothole detection accuracy and speed.
Wearable Technology to Increase Self-Awareness of Low Back Pain: A Survey of Technology Needs among Health Care Workers
Authors: Ferrone Andrea , Napier Christopher , Menon Carlo
Published: December 2021

Low back pain (LBP) is a leading contributor to musculoskeletal injury worldwide and carries a high economic cost. The healthcare industry is the most burdened, with nurses, in particular, being highly prone to LBP. Wearable technologies have the potential to address the challenges of monitoring postures that contribute to LBP and increase self-awareness of workplace postures and movements. We aimed to gain insight into workers’ perceptions of LBP and whether they would consider using wearable monitoring technologies to reduce injury risks. We conducted a cross-sectional survey to gather information from a selected population of nurses. Sixty-four participants completed the survey, and data were analyzed with the support of Machine Learning techniques. Findings from this study indicate that the surveyed population (64 nurses) is interested in these new approaches to monitor movement and posture in the workplace. This technology can potentially change the way ergonomic guidelines are implemented in this population.
Value Iteration Networks with Double Estimator for Planetary Rover Path Planning
Authors: Jin Xiang , Lan Wei , Wang Tianlin , Yu Pengyao
Published: December 2021

Path planning technology is significant for planetary rovers that perform exploration missions in unfamiliar environments. In this work, we propose a novel global path planning algorithm, based on the value iteration network (VIN), which is embedded within a differentiable planning module, built on the value iteration (VI) algorithm, and has emerged as an effective method to learn to plan. Despite the capability of learning environment dynamics and performing long-range reasoning, the VIN suffers from several limitations, including sensitivity to initialization and poor performance in large-scale domains. We introduce the double value iteration network (dVIN), which decouples action selection and value estimation in the VI module, using the weighted double estimator method to approximate the maximum expected value, instead of maximizing over the estimated action value. We have devised a simple, yet effective, two-stage training strategy for VI-based models to address the problem of high computational cost and poor performance in large-size domains. We evaluate the dVIN on planning problems in grid-world domains and realistic datasets, generated from terrain images of a moon landscape. We show that our dVIN empirically outperforms the baseline methods and generalize better to large-scale environments.
The Case of the Kumbhalgarh Wildlife Sanctuary and Camel Pastoralism in Rajasthan (India)
Authors: Köhler-Rollefson Ilse , Rathore Hanwant Singh
Published: December 2021

The Indian forest management system introduced during colonial times has led to the progressive loss of the grazing rights of the country’s pastoralists, culminating in the abolishment of grazing fees and replacement with grazing fines in 2004. This scenario has had a negative knock-on effect on the conservation of many of the livestock breeds that pastoralists have developed in adaptation to local environments and that are the basis of the country’s food security. This paper illustrates the dilemma with the example of the Kumbhalgarh Wildlife Sanctuary (KWS) in Rajasthan that represents the traditional monsoon grazing area for local camel, sheep and goat pastoralists. Raika herders have engaged in a long-standing but losing legal battle with the state for their continued seasonal access to this area. This situation contributes to the rapid decline of the camel which is an iconic part of Rajasthan’s desert identity, a major attraction for tourists and was declared state animal in 2014. The aims of the forest department to conserve wild animals and those of pastoralists and camel conservationists could easily be integrated into a more equitable governance system as is endorsed by Aichi Target 11 of the CBD Strategic Plan 2011–2020. However, deeply engrained concepts about nature being separate from (agri-)culture, as well as unequal power structures, stand in the way.
Challenges and Design Strategies for Conversion-Based Anode Materials for Lithium- and Sodium-Ion Batteries
Authors: Kim Hyunwoo , Kim Dong In , Yoon Won-Sub
Published: December 2021

Although lithium-ion batteries are currently the most reliable power supply system for various mobile applications, further improvement in energy density is still required as the need for batteries in large energy-consuming devices is rapidly growing. However, in the anode, the most widely commercialized graphite-based anode materials almost face theoretical limitations. In addition, sodium-ion batteries have been actively studied to replace expensive charge carriers with cheaper ones. Accordingly, conversion-based materials have been extensively studied as high-capacity anode materials in both lithium-ion batteries and sodium-ion batteries because their theoretical capacity is twice or thrice higher than that of insertion-based materials. This review will provide a comprehensive understanding of conversion-based materials, including basic charge storage behaviors, critical drawbacks that should be overcome, and practical material design for high-performance.

Ontološki ključ razumijevanja slike Mrtvi Krist u
grobu Hansa Holbeina mlađeg
Authors: Miščin Daniel
Published: December 2021

Prihvaćajući argumente u prilog tzv. kartuzijanskoj hipotezi, tj. stajalištu da je Holbeinova slika Mrtvi Krist u grobu izvorno zamišljena kao nadgrobni spomenik u baselskoj kartuziji, autor analizira tekst epitafa s kojim je ona trebala činiti cjelinu. Kao rezultat te analize, autor naglašava važnost ontološkog značenjskog sloja tog epitafa u čijem svjetlu razvija ontološki ključ za razumijevanje te slike, povezujući ga sa smislom tradicionalne kartuzijanske opomene memento mori. Uzimajući u obzir ontološki smisao te opomene, tjeskoba promatrača Holbeinova Mrtvog Krista tumači se na tragu refleksije o pojmu Ništa (das Nichts) u egzistencijalnoj analici Martina Heideggera i Bernharda Weltea.
Uloga oca u problematici pobačaja
Authors: Šehić Damir
Published: December 2021

Rad iz pozicije kršćanskog nauka i moralne teologije sagledava probleme očinstva izostavljene u govoru o pobačaju, od uloge muškarca kao oca, prava oca u odlučivanju o vlastitom djetetu pa sve do oca kojeg zakon ne spominje. Perspektiva moralne teologije pokušava uvrstiti psihološke, sociološke i pravne rezultate koje teološki vrjednuje. Prvi dio rada donosi govor o očinstvu iz kršćanske perspektive, temeljenom na objavi Božjeg očinstva, dok se drugi osvrće na psihološku dimenziju očinstva. Treći dio teološki vrjednuje ulogu oca u fenomenologiji pobačaja, donoseći novost jer teološki vrjednuje tri modela ponašanja muškaraca poznata na psihološkom i pravnom području. Dotiče se pritom i društveno-pravnog uređenja prava oca u hrvatskom zakonodavstvu, koje još uvijek traži rješenje. Teološko promišljanje o autentičnoj ulozi oca ostvarenje njegova poziva vidi u nasljedovanju Evanđelja i kršćanskog života.

Ciudades y urbanismo en el mundo antiguo: una introducción
Authors: Jaruf Pablo
Published: December 2021

El objetivo de este artículo es introducir de manera breve los debates en torno al concepto de ciudad y de urbanismo, con especial referencia al mundo antiguo. Con respecto a la ciudad, se sintetizan los aportes realizados por las ciencias sociales desde mediados del siglo XIX en adelante, resaltando aquellos estudios comparativos que han pretendido identificar sus rasgos comunes en distintas regiones y períodos. También se presta atención a aquellos enfoques que enfatizan las nociones nativas del pasado sobre aquello que nosotros hoy consideramos como ciudades. A continuación, se profundiza en los aportes del urbanismo, a partir del cual se comienza a estudiarlas como nodos de un sistema jerárquico de asentamientos, predominando entonces las relaciones y oposiciones con respecto a otras formas de ocupación del territorio, como aldeas rurales o tiendas de nómades. Por último, antes de presentar las contribuciones que forman parte de este dossier, se propone una definición de ciudad.
Redes de ciudades en China imperial temprana (siglos III a.e.c.-III e.c.). Control territorial y lógicas de parentesco
Authors: Villagrán Ignacio , Fini Melina
Published: December 2021

El área de la llanura fértil del río Amarillo en el norte de China se caracteriza por la temprana aparición y acelerada proliferación de los núcleos urbanos, y el rápido desarrollo de las ciudades amuralladas desde el siglo XV a.e.c. En este artículo, nos proponemos investigar las lógicas de parentesco subyacentes en el entramado de ciudades durante el período imperial temprano, con especial énfasis en la dinastía Han (206 a.e.c.-220 e.c.). Revisaremos la fundación de ciudades en relación con los procesos de expansión territorial y de consolidación de un esquema de gobierno que mantuvo las tensiones entre los magistrados designados para cumplir con funciones administrativas en las provincias del imperio, por un lado, y los nobles hereditarios que formaban parte del clan imperial, por el otro. A pesar de los problemas que se derivaban de la duplicación de figuras de poder en los principales centros urbanos del imperio temprano, fue gracias a este esquema de gobierno dual que las redes de ciudades permitieron la expansión y control territorial que facilitó el gobierno de la dinastía Han por más de cuatro siglos.

Published: December 2021

A portfolio concerns the formation of the composition of multiple assets to obtain optimum results. At the same time, Value at Risk is a technique in risk management to measure and assess parametrically (variant and co-variant), Monte-Carlo, and historical simulation. This research employed historic simulation because normal distribution is not required from returns and is a Value at Risk calculation model that is determined by the past value on produced return asset, in which this research aimed to determine the Markowitz model positive shares and Value at Risk in the portfolio by using historical simulation. The Markowitz model found eight shares with positive expected returns, which are as follows: BBCA, BBRI, BRPT, EXCL, ICBP, INDF, MNCN, and TPIA. The BBCA has the most significant exposure of all the shares with the amount of Rp 2.287.200.440.000, while the TPIA has the smallest exposure of all the shares with the amount of Rp 58.899.375.000. Further, the EXCL has the largest VaR with the amount of Rp 236.189.538.497, while the TPIA and ICBP had no VaR losses because the VaR of TPIA and ICBP is Rp 0 and Rp -1.407.719.893, respectively, along with the INDF as the share with the smallest VaR of Rp 18.513.213.620. The most significant exposure average is Rp 719.246.318.375, while the largest VaR average is Rp 76.827.608.341,3. As long as the VaR did not exceed the exposure value, the investors will be safe and have no loss.
NUMERICAL RESULTS OF MIXED CONVECTION FLOW OVER A FLAT PLATE WITH THE IMPOSED HEAT AND ANGLE OF INCLINATION
Authors: Ghani Mohammad
Published: December 2021

In this paper, the numerical results of mixed convection flow over a flat plate with the imposed heat and different angles of inclination are established by applying the finite difference method of Crank-Nicolson. We further compare these numerical results with the case of non-mixed convection flow.  The velocity and temperature profiles are decreased when the different values of the Prandtl number (Pr) are increased. Meanwhile, the velocity profiles are increased, when the different values of angle of inclination (alfa) and mixed convection parameter (lambda) are increased. The mixed convection flow case (lambda=1.5) is affected by the external force, so the velocity of convection flow is higher than the non-mixed case (lambda=0).
MEMBANGUN SIKAP POSITIF UNTUK MENGHINDARI SIKAP PHOBIA MATEMATIKA
Authors: Ismail Yamin
Published: December 2021

Math phobias are anxiety on math skills that happen to most learners. Anxiety is demonstrated by the existence of continuous fear against the object of mathematics and its learning situation. To avoid this, the facilitator must create a situation that allows the learners to build their confidence in math tasks. Math is characterized by abstract ideas in the form of abstract symbols that require delivery within a less abstract language to avoid understanding the idea. A positive attitude towards mathematics appears closely related to the previous experience in both the mathematical object and the classroom situation. Therefore, developing a positive attitude against math phobia requires the content to be delivered in an attractive manner in every learning process. The presentation of mathematical formulas should be adjusted according to the learning basic ability and sometimes accompanied by an inductive approach. As the facilitator of learning, the teacher must seek a learning environment that can encourage learners to behave positively and passionately in learning mathematics.

Entre decencia y dignidad:
Authors: Paulizzi María Cora
Published: December 2021

El presente artículo, desde una perspectiva crítica y de gubernamentalidad, pretende analizar los modos cómo se configuran las relaciones entre prácticas y lógicas de gobierno dirigidas a las poblaciones pobres y desocupadas y las prácticas de resistencia a ser gobernades en los términos que disponen las políticas sociolaborales públicas, atendiendo al caso de la Fundación de Trabajadores/as Desocupados/as de Gral. Mosconi (en adelante, FUNDATRAD-UTD). Para realizar dicha tarea vamos a centrar nuestro artículo en torno de dos ejes simultáneos de análisis. Por un lado, un ejercicio crítico, analítico y descriptivo en torno del campo de las políticas públicas sociolaborales centradas en la inclusión, la economía social y el trabajo decente en Argentina entre 2003 y 2015. Por otro lado, y en estrecha relación abordamos las prácticas de resistencia y autogobierno de los/as trabajadores/as desocupados/ as aunados/as en FUNDATRAD, en un tejido transaccional de negociación y reinvención para con las políticas sociolaborales públicas, puntualizando en torno del trabajo y la dignidad. De este modo, en un dinámico haz de relaciones locales y cotidianas, es puesta en juego la relación múltiple, heterogénea y siempre abierta entre gobernades y gobernantes, apostando a la producción autónoma de la subjetividad colectiva.
Implementation of Community Wetlands for the sanitation of the Cajititlan Lake, Jalisco
Authors: Caro-Becerra Juan Luis , Vizcaíno-Rodríguez Luz Adriana , Luján-Godínez Ramiro , Michel-Parra J. Guadalupe
Published: December 2021

Wetlands are systems that promote the sustainability and development of a society. The goal of this research was the implementation of a prototype aquatic garden to assess the quality of water in Cajititlán Lake, using sewage treatment plants with the purpose of removing nutrients, phosphates and nitrates among others parameters. This was made possible by floating structures containing aquatic vegetation species like.: Typha latifolia, Lemna minor, Canna indica, Iris pseudacorus, Equisetum arvense, etc. whose basic function is to retain nutrients through phytoremediation processes. The results indicate that the implementation of community wetlands made possible to reduce BOD levels from 220 mg/lt to 12 mg/lt across a surface of 120 m², treating a flow rate of approximately 5.30 gal/min to obtain an effluent in accordance with norm NMX-AA-012-SCFI. It is concluded that community wetlands are suitable ecological alternatives for the treatment of the wastewater discharged directly into the lake.
ВЗАЄМОЗБЛИЖЕННЯ НАУКОВОЇ ІСТИНИ І ЦІННОСТЕЙ У СУЧАСНОМУ НАУКОВОМУ ПІЗНАННІ
Authors: Заглада В.
Published: December 2021

Статтю присвячено аналізу відношення "істина – цінність" у рамках когнітивного підходу до наукового пізнання. Акцент зроблено на тих трансформаціях, які відбулися у ХХ ст. в епістемології і філософії науки, щодо трактування наукової істини. Сьогодні для природничо-наукового пізнання кореспондентська концепція істини залишається пріоритетною. При цьому в певних ситуаціях природничо-наукового пізнання адекватнішою стає когерентна концепція істини, яка зводить проблему істинності до критерію самоузгодженості, або несуперечливості.
МІФОТВОРЧІСТЬ В КОМУНІКАТИВНОМУ ПРОСТОРІ: ДО ПИТАННЯ КОНЦЕПТУАЛІЗАЦІЇ ПРОБЛЕМИ
Authors: Слюсар М.
Published: December 2021

Здійснено аналіз феномену міфотворчості, що відбувається в сучасній комунікації завдяки популярній літературі, кіномистецтву та анімації тощо. На основі розгляду змістового насичення таких понять, як "міфологізація", "деміфологізація", "міфологія" та "міфізація", автор дійшов думки, що вони фіксують неоднакові явища при створенні чи поширенні міфів, в тому числі й новітніх міфів, які широко представленні в сучасному комунікативному просторі завдяки ЗМІ, рекламі, масовій культурі та популярному мистецтву, політичній діяльності різних інституцій сучасного суспільства. Запропоновано розглядати міфотворчість свідомим продукуванням, створенням з боку людини конкретних новітніх міфів, точніше міфологем, наприклад з виробничих потреб в масовій культурі, популярному мистецтві. Також стверджуємо, що на відміну від міфізації, міфотворчість має позитивне значення для духовного життя сучасного суспільства. Стверджуємо, що однією із вагомих причин існування міфотворчості є людське бажання виходити за межі повсякденності, щоб уникнути нудьги, втоми і розважитися. Ще одним важливим її стимулом є прагнення відійти, хоча б на деякий час, від логіки утилітаризму, меркантилізму, яка активно пропагується в сучасному суспільстві.
Про містичний зміст суфійської філософії
Authors: Панахова К.
Published: December 2021

У статті розглядаються основні характеристики містики, як є характерними рисами суфізму. Суфізм, в цілому, слід розуміти і як моральне вчення, і як філософію знання. Суфій, який відсуває душу і дух від матеріальних відносин, заповнює свою душу моральною божественною красою, і, таким чином, осягає духовну зрілість, яка дозволяє бути в контакті з Активним розумом. При цьому розвивається як моральна, так і епістемологічно зріла самосвідомість. Проста самосвідомість до досягнення цієї зрілості – це двозначна самосвідомість, пов'язана з реальним світом. Аналіз проблеми містицизму проводиться на основі різних наукових джерел. Підкреслюється, що містика суфійця справила певний вплив на розвиток духовної культури Сходу.
