Simulation of Human Ear Recognition Sound Direction Based on Convolutional Neural Network
Authors: Wang Zhuhe , Li Nan , Wu Tao , Zhang Haoxuan , Feng Tao
Published: July 2020

In recent years, more and more people are applying Convolutional Neural Networks to the study of sound signals. The main reason is the translational invariance of convolution in time and space. Thereby the diversity of the sound signal can be overcome. However, in terms of sound direction recognition, there are also problems such as a microphone matrix being too large, and feature selection. This paper proposes a sound direction recognition using a simulated human head with microphones at both ears. Theoretically, the two microphones cannot distinguish the front and rear directions. However, we use the original data of the two channels as the input of the convolutional neural network, and the resolution effect can reach more than 0.9. For comparison, we also chose the delay feature (GCC) for sound direction recognition. Finally, we also conducted experiments that used probability distributions to identify more directions.

Kidney transplantation is the surgical operation by which one of the two original kidneys is replaced with another healthy one donated by a compatible individual. In most cases, donors are recently deceased. There is the possibility of withdrawing a kidney from a consenting living subject. Usually, living donors are direct family members, but they could be volunteers completely unrelated to the recipient. A much-feared complication in case of kidney transplantation is the appearance of infections. These tend to arise due to immune-suppressor drugs administered as anti-rejection therapy. In this review, we describe the gastrointestinal complications that can occur in subjects undergoing renal transplantation associated with secondary pathogenic microorganisms or due to mechanical injury during surgery or to metabolic or organic toxicity correlated to anti-rejection therapy. Some of these complications may compromise the quality of life or pose a significant risk of mortality; fortunately, many of them can be prevented and treated without the stopping the immunosuppression, thus avoiding the patient being exposed to the risk of rejection episodes.
Structures of Pt(0)P3, Pt(0)P4 and Pt(II)P4 – Distortion isomers
Authors: Melník Milan , Mikuš Peter
Published: July 2020

In this review are analyzed and classified crystallographic and structural parameters of P(0)P3, Pt(0) P4 and Pt(II)P4 derivatives – distortion isomers. Some of the isomers are differing not only by degree of distortion but also by crystal class. There are three types of organo-phosphines which build up the respective geometry about the platinum atoms. In Pt(0)P3 a distorted trigonal planar geometry is build up by three monodentate PPh3 ligands. In Pt(0)P4 a tetrahedral geometry with various degree of distortion is build up by a pair of homo-bidentate ligands. In Pt(II)P4 isomers a square-planar geometries with various degree of distortion are build up by bidentate-P,P’donor ligands, (except one example of isomers, where a tetradentate is involved). The bidentate-P,P’-donor ligands form: four-(PNP,PCP), five-(PC2P) and six-(PC3P) metallocyclic rings. The tetradentate forms five-(PC2P). There are some cooperative effects between Pt–P bond distances and the metallocyclic rings, and at the same time a distortion of the respective geometry increases.
The effect of zeolite on inkjet coated paper surface properties and deinking
Authors: Ozcan Arif , Tutak Dogan
Published: July 2020

Coatings are generally applied for opacity, smoothness and gloss on the paper surface. Pigments such as CaCO3, Kaolin-Clay and Zeolite are used, and natural or synthetic binders are used. In this study, coatings using the CaCO3, Kaolin-Clay and Zeolite pigments on 80 gr/m2 high grade papers were made. PVOH was used as binder. Following coating, papers were processed through supercalendering and printed with inkjet printer. Using INGEDE method 11p. recycling process printed papers were deinked. The optical properties of the recycled papers obtained after the deinking treatment, were compared with the unprinted papers. At the end of the study, the effect of coating on paper surface and the recycling performances of the inkjet printed papers were revealed. It was determined that the papers in which zeolite was used as a pigment were better, in terms of both surface properties and recycling performance when surface properties and recycling performance of coated papers were examined. When all the results were compared, it was found that the performances of coatings for which zeolite was used were much better than coatings such as CaCO3 and Kaolin-Clay, both in terms of surface coating properties such as opacity, roughness and gloss and recycling results such as brightness.
Insulative effect of plastic mulch systems and comparison between the effects of different plant types
Authors: Snyder Kayla , Murray Christopher , Wolff Bryon
Published: July 2020

To address agricultural needs of the future, a better understanding of plastic mulch film effects on soil temperature and moisture is required. The effects of different plant type and mulch combinations were studied over a 3.5-month period to better grasp the consequence of mulch on root zone temperature (RZT) and moisture. Measurements of (RZT) and soil moisture for tomato (Solanum lycopersicum), pepper (Capsicum annuum) and carrot (Daucus carota) grown using polyolefin mulch films (black and white-on-black) were conducted in Ontario using a plot without mulch as a control. Black mulch films used in combination with pepper and carrot plants caused similar RZTs relative to uncovered soil, but black mulch film in combination with tomato plants caused a reduction in RZT relative to soil without mulch that increased as plants grew and provided more shade. White-on-black mulch film used in combination with tomatoes, peppers or carrots led to a reduction in RZT relative to soil without mulch that became greater than the temperature of soil without mulch. This insulative capability was similarly observed for black mulch films used with tomato plants. Apart from white-on-black film used in combination with tomatoes, all mulch film and plant combinations demonstrated an ability to stabilize soil moisture relative to soil without mulch. RZT and soil moisture were generally stabilized with mulch film, but some differences were seen among different plant types.

Published: July 2020

Objectives

The objectives were to assess the microbiological stability and the physical enclosure integrity of the overwrapping for batch production of standard cytotoxic injectable solutions.

Methods

Broth culture media were used in place of cytotoxic drugs to assess the worst case in term of microbiological contamination risk. Iterative sterility tests on batches were performed for 60 days using rapid microbiological method. Validation of microbiological growth of culture media was assessed by direct inoculation of <100 CFU/mL of six microbiological strains recommended by European Pharmacopeia. Validation of the ability of growth of microorganisms in 11 cytotoxic solutions and one monoclonal antibody was assessed using eight strains. In addition, the physical integrity of the seal of the overwrapping containing cytotoxic preparations was assessed by dynamometric method and dye penetration test.

Results

No microbiological contamination was observed on all units of batches for 60 days of investigation. The ability to detect microbiological growth in cytotoxic solutions was validated for the eight challenge microorganisms after 1/10 dilution for cytotoxic investigated, except for 5 Fluorouracil, gemcitabine and cisplatin. In addition, physical integrity testing of the seal of overwrapping pointed out the need of specific validation of heatsealer and operator education.

Conclusions

Besides physico-chemical testing, microbiological stability testing combined to physical integrity testing is the additional part of the development method for batch production of sterile drugs in hospital.
An overview on radiometric assessment and excess lifetime cancer risk of soil in Pakistan by using High Purity Germanium (HPGe) detector
Authors: Rehman Jalil ur , Alam Iftikhar , Ahmad Nisar , Hameed Aslam , Nazir Alia , Ullah Hafeez , Hussain Altaf
Published: July 2020

Objectives

The aim of this study is to compare the natural radioactivity and excess life time cancer risk (ELCR) factor of soil in different regions of Pakistan during last decade. Soil contains various elements and compounds including naturally occurring radioactive elements (238U, 232Th, 40K and 137Cs). Human being, animals and plants are in health risk by contaminations of natural radioactivity in soil and environmental radiometric pollution. Transferring of large amount of the natural radioactive elements in human body by nutrients may cause carcinogenic effects in human body. Pakistani soil has six types as Indus Basin Soil, Bongar Soil, Khaddar Soil, Indus delta soil, Mountainous soil and Sandy Desert Soil. In some northern region of Pakistan, naturally occurring radioactive rocks like uranuium-238 and iridium concentrations present in Gharwandi, Aram, Kingri S, Vitakri Fort Munro, Dera Bugti, Kohlu and Sibbi districts.

Methods

In this reviewed data, gamma rays spectroscopy used to determine the concentrations of 238U, 232Th and 40K with the help of High Purity Germanium (HPGe) detectors. Only the data of HPGe detector collected because of comparisons of different regions of Pakistan.

Results and conclusions

Mostly, different gamma rays energy peaks of relevant daughter radionuclides of radioactive element were used such as the energy peak lines of daughter radionuclides 214Pb (295.21 and 352 KeV) and 214Bi (609 and 1,120 KeV) used for calculating the 226Ra concentration in soil. In the recent study, it is concluded that average values of concentrations of natural radioactivity in soil in central and north regions of Pakistan are higher than permissible limit but found permissible range in south region of Pakistan. Mean values of ELCR factor were found higher, equal and lower in central, north and south regions than permissible limit, respectively. Generally, no serious health hazard due to natural radioactivity in soil were found.
Der Sinn der Ökonomisierung
Authors: Peetz Thorsten
Published: July 2020

Der Artikel argumentiert anhand von vier Beispielen aus den Feldern Bildung und Intimität, dass Ökonomisierungsdiagnosen oft problematische Züge aufweisen. Erstens sind sie häufig gesellschaftstheoretisch unterspezifiziert und deshalb analytisch unpräzise. Zweitens laufen sie in methodologische Probleme, wenn Semantik und Struktur, Formal- und Tätigkeitsstruktur sowie Deutungen bzw. Eigentheorien der Befragten und die Logik ihrer Praxis nicht konsequent unterschieden werden. Entsprechend plädiert der Artikel für eine rekonstruktive Ökonomisierungsforschung, die gesellschaftstheoretische Präzision mit methodischer Sorgfalt verbindet, um gesellschaftlichen Veränderungsprozessen auf die Spur zu kommen.
Deutungsmuster als forschungsheuristisches Konzept
Authors: Pfister Sandra Maria
Published: July 2020

Deutungsmuster stellen ein fruchtbares Konzept zur Eingrenzung sozialer Wissensbestände dar. Wenig überraschend erfreut es sich einer breiten Anwendung im deutschsprachigen Raum. Dennoch ermangelt es einer klaren Konzeptualisierung sowie eines klaren empirischen Forschungsprogramms. Es lässt sich allerdings über den Grundkonsens der Deutungsmustertheoretikerinnen zum konzeptionellen Kern der Deutungsmuster vordringen, der im vorliegenden Beitrag herausgearbeitet wird. Anhand eines empirischen Anwendungsbeispiels zu den Deutungsmustern der Katastrophe wird zudem ein empirisches Forschungsprogramm zur Rekonstruktion des Raums an Deutungsmustern vorgestellt und eine flexible, aber dennoch theoretisch geleitete Anwendung als forschungsheuristisches Konzept anstelle einer essentialistischen a-priori Definition des Konzepts, seiner Strukturdimensionen, und seiner raum-zeitlichen Verortung befürwortet.
The voiceless in The Voice: A multimodal critical discourse analysis
Authors: Er Ibrahim
Published: July 2020

This article highlights the importance of multimodality in the study of discourse with a discussion of a segment from the Turkish adaptation of the global television format, The Voice. In the segment under discussion, a contestant is disqualified from the show by the host for her allegedly disrespectful style of speech towards the coaches. Departing from traditional (sociolinguistic) critical discourse analysis, the article seeks to unveil the deep power discourse hidden in the multimodal landscape of the show by extending the scope of discourse analysis to include both linguistic and non-linguistic modes of communication and representation such as the camerawork, and mise-en-scene. The findings shed light on the inherently asymmetrical nature of the show and how the contestant's highly non-standard language and manners are demonized (multimodally) while the coaches and the host find a relatively less judgmental environment as the “authority” in the show.
El desencantamiento de la Escuela: sus cambios y zarandeos en la era posindustrial
Authors: Mosquera Mosquera Carlos Enrique , Ramírez Martínez Jorge Enrique
Published: July 2020

El presente artículo pretende reflexionar sobre los zarandeos y cambios que experimenta la escuela en la era posindustrial a través de dos categorías: 1) el desencantamiento de la escuela y su desinstitucionalización, y 2) la civilidad: una conquista a través de la estructura de la socialización. En este se propone que, frente a la caoticidad, la desinstitucionalización y la dispersión generalizada de la escuela, así como frente a la subjetividad en la era posmoderna, se posibilite desde los procesos educativos un diálogo entre algunas estructuras del pasado y del presente, para que el proceso de licuefacción no sea tan veloz y nos arrastre a la pérdida de sentido del mundo y de la vida. También se propone retomar la estructura social de la escuela para formar una civilidad en los sujetos educativos, pero alejada del disciplinamiento para no caer en la barbarie.

Luego de aplicar una metodología de investigación documental, se presentan las nociones encontradas sobre las dimensiones de la mediación pedagógica en el contexto de la comunicación de la cultura visual en los procesos educativos virtuales, y la reflexión sobre la construcción de subjetividades en estas interacciones. Es así como el artículo se organiza en tres secciones a modo de nodos conceptuales: el primero es la mediación pedagógica en los entornos virtuales de aprendizaje; el segundo es la evaluación de la mediación pedagógica, y el tercero aborda subjetividad y tecnología: la expresión en la narrativa visual. Luego, a modo de contrastación, se presenta lo encontrado en la observación de los cursos y las respuestas de los estudiantes frente a la propuesta de la narrativa visual de los cursos virtuales.
Mutant Evolution in Spatially Structured and Fragmented Expanding Populations
Authors: Wodarz Dominik , Komarova Natalia L
Published: July 2020

Mutant evolution in spatially structured systems is important for a range of biological systems, but aspects of it still require further elucidation. Adding to previous work, we provide a simple derivation of growth laws that characterize the number of mutants of different relative fitness in expanding populations in spatial models of different dimensionalities. These laws are universal and independent of “microscopic” modeling details. We further study the accumulation of mutants and find that, with advantageous and neutral mutants, more of them are present in spatially structured, compared to well-mixed colonies of the same size. The behavior of disadvantageous mutants is subtle: if they are disadvantageous through a reduction in division rates, the result is the same, and it is the opposite if the disadvantage is due to a death rate increase. Finally, we show that in all cases, the same results are observed in fragmented, nonspatial patch models. This suggests that the patterns observed are the consequence of population fragmentation, and not spatial restrictions per se. We provide an intuitive explanation for the complex dependence of disadvantageous mutant evolution on spatial restriction, which relies on desynchronized dynamics in different locations/patches, and plays out differently depending on whether the disadvantage is due to a lower division rate or a higher death rate. Implications for specific biological systems, such as the evolution of drug-resistant cell mutants in cancer or bacterial biofilms, are discussed.

Authors: Taype Waldo , Amado José
Published: July 2020

La enfermedad por nuevo coronavirus se detectó en Perú en marzo de 2020, diseminándose rápidamente, produciendo afecciones respiratorias graves y alta mortalidad. En el servicio de emergencia se debe implementar medidas de aislamiento de pacientes con ambientes específicos para casos sospechosos y confirmados (según gravedad) y definir flujogramas de atención basados en datos objetivos y fácilmente evaluables. Asimismo, se deben establecer pautas para realizar exámenes auxiliares y adoptar tratamiento según la mejor evidencia disponible. Las medidas de higiene y equipos de protección personal deben estar asegurados para evitar el contagio, así como suspender visitas y acompañamiento de familiares; pero a la vez se debe asegurar adecuado flujo de información (de preferencia virtual) para familiares y el propio personal. Es necesaria la rápida adecuación de los planes y recursos (materiales y humanos) para responder a la creciente demanda de pacientes, siendo indispensable la participación interdisciplinaria.

En la actualidad nos encontramos en una pandemia generada por el SARS-CoV 2, un virus que en poco tiempo se expandió por todos los continentes. En este escenario, es vital que el personal de salud se proteja de la forma más eficiente posible, pues ellos son los que se encargan de librar la lucha contra esta patógeno. Sin embargo, una parte esencial del equipo de protección personal -los respiradores N95- ha comenzado a escasear en los países más golpeados por la pandemia. Una alternativa factible a los respiradores N95 son los respiradores elastoméricos. No obstante, esta alternativa no es mencionada en los documentos técnicos de muchos países latinoamericanos ni es mencionada por la Organización Panamericana de la Salud en sus recomendaciones para el equipo de protección personal. Es por ello que presentamos las principales características de los respiradores elastoméricos en relación a los respiradores N95.

El objetivo fue analizar el impacto de contextos socio-económicos diferentes sobre la declaración de ganancias ante distintos niveles de presión fiscal. Adicionalmente, se examinó el efecto de la fuente del dinero. En el primer estudio, estudiantes de Argentina y España realizaron una tarea de resolución de anagramas para generar ganancias de manera endógena y declararon sus ganancias ante distintos niveles de presión fiscal. En el segundo estudio, estudiantes de Argentina dispusieron de dinero experimental al inicio del estudio y también indicaron su declaración ante distintos niveles de presión fiscal. Se observaron diferencias significativas entre los participantes de Argentina y España en altos índices de presión fiscal. Además, cuando el dinero era ganado los participantes declararon significativamente más en comparación a cuando era brindado por el experimentador. Esto resalta la importancia de considerar aspectos socioculturales al definir las políticas fiscales y el impacto de la fuente del dinero en la declaración.

Detection of mineralogically accentuated biogenic structures with high-resolution geophysics: implications for ichnology and geoecology
Authors: Buynevich Ilya V.
Published: July 2020

Identification and mapping of small-scale physical and biogenic structures in sand has been a challenge to sedimentologists and ichnologists. Under natural conditions, biogenic activity (trampling tracks, burrows) alter primary sedimentary structures, but also serve as important paleoenvironmental indicators of geotechnical properties of sediments, omission surfaces, and ecosystem dynamics. Therefore, the ability to recognize such structures as anomalies in shallow subsurface, especially when using indirect non-invasive methods, such as geophysical imaging, is an important aspect of assessing their relative contribution to the overall erosional-depositional record. This study presents experimental evidence of the viability of two highresolution geophysical methods in detecting sediment deformation that mimics shallow animal traces. High-frequency (800 MHz) ground-penetrating radar (GPR) imaging aided in visualizing a buried depression produced by a deer hoofprint cast indenter, with high-amplitude reflection return enhanced by a heavy-mineral concentration (HMC). Bulk in situ low-frequency (930 Hz), low-field magnetic susceptibility (MS) experiment supported the theoretical pattern of a decrease in MS over the thickest cover sand (maximum indentation depth) to ~0 mSI and the highest values over raised HMC horizon (marginal ridge; >8 mSI). Because both methods are affected by the presence and relative abundance of heavy minerals, the present approach can be applied in most siliciclastic settings. This study demonstrates the promise of extending the 2D visualization of subsurface targets to 3D datasets, with potential implications for sedimentological, ichnological, archaeological, and geoecological research that involves animal-sediment interaction at different scales.
Time series analysis of karst breakdown development on the potassium salt deposit areas within Precarpathian region
Authors: Chepurnyi Ihor V. , Bagriy Serhii M. , Kuzmenko Eduard D. , Chepurna Tetiana B.
Published: July 2020

The work is devoted to the analysis of karst breakdown development over time within the area of the Kalush-Golynske and Stebnytske potassium salt deposits. A study of the relationship between the development of karst breakdowns with the factors influencing their development in natural conditions and in the conditions of natural-technogenic systems is presented. Time series of karst breakdowns in the Kalush-Golynske and Stebnytske deposits of potassium salt were selected for the investigation. The time series reflect the number of formed failures of the earth’s surface due to karst processes. Climatic (average annual temperature and annual precipitation), heliophysical (solar activity), seismic (number and energy of earthquakes), hydrogeological (groundwater levels) were chosen as such factors. Breakdown phenomena, which are included in the time series of their longterm dynamics, are associated with different hydrodynamic zones of karst processes. For these zones, the indirectness degree of the influence of the selected for the analysis factors is different and the meteorological parameters are more effective in the supply zone, seismic factors work in all zones. Statistical methods such as correlation analysis, calculation of autocorrelation and cross-correlation functions, spectral analysis are used for the analysis of the time series. Statistical regularities in the series of karst breakdown development for Kalush-Golynske and Stebnytske potassium salt deposits and between the selected natural time factors and karst series have been established, which allows asserting the indirect influence of natural component of karst activation. The presence of periodic components in the long-term series of karst breakdowns should be associated with the natural factors that indirectly activate karst processes. These factors should be investigated and taken into account when creating temporal prognostic models for the development of karst breakdown processes within the deposits of potassium salt of Precarpathia.

A large number of monuments of archeology, architecture, history, nature, developed centers of traditional crafts and trades, and a fairly dense network of sacred structures stands out among the objects of recreation.Forests and reservoirs play an important role in the recreational area. Conservation areas, which are valuable in recreational terms, occupy 1.2% of the area of the region. Mineral waters and healing properties of the forest climate are the main manifestations of the recreational properties of space in Cherkasy region. A significant contribution to the resource component of the recreational potential of Cherkasy region was made by a large number of historical and cultural reserves – of which there are 8 in the region, two of which have national status. The sanatorium-resort and preventive-health establishments of the region are considered. It is established that they are represented by sanatoriums (including children’s ones), tourist bases and other recreation establishments, whose number is decreasing every year. It is established that according to the capacity index, the largest number of tourists can spend the night at such resorts as «Svitanok» in the village of Svidovok, «Moshnohirya» in the village of Budyshche, «Akvadar» in the town of Mankivka, children’s «Ruska Polyana» in the village of Ruska Polyana of Cherkasy district and «Ukraine» and «Sosnoviy bir», which are located in the city of Cherkasy. The most significant recreation facilities are located in the village of Vigraev, Korsun-Shevchenkivskyi district («Ros» VAT «SPK Merydian», «Dubky», «Ros» (Relay and Automation Plant, Kazar-Ros), Prokhorovka village, Kaniv district («Sonyachna», «Komsomolska»), in the village of Chapayevka of the Zolotonisky district («Prydniprovska»).It is established that there is an increase in the number of subjects of tourist activity. More than 80% of them are travel agencies that are not focused on domestic and inbound tourism. It is found that the transport structure of Cherkasy region is represented by all major passenger types (rail, road, river and air) and its functioning is provided by appropriate infrastructure. The rating of level of development of Cherkasy region on such indicators as hotel infrastructure, restaurant infrastructure, healthimprovement establishments, archeology monuments, architectural monuments and historical monuments was conducted. It is revealed that five districts of the region (Zolotonisky, Kaniv, Uman, Cherkasy, Chyhyryn) have a high level of tourist potential supply, ten districts of the region have a medium level of provision (Horodyshche, Zvenihorod, Kamyansky, Korsun-Shevchenkivsky, Mankiv, Smilyansky, Talne, Khrystyniv, Chornobaiv, Shpolyan), five areas are outsiders with low levels of tourism potential (Drabiv, Zhashkiv, Katerynopil, Lysyansky, Monastyrische).
Cottage settlements in capital region of Ukraine

In this paper, the phenomenon of suburbanization in Ukraine is considered for the first time on the example of cottage settlements of the capital region. The issue of cottage settlements has not been studied specifically in Ukrainian human geography. A review of the achievements of foreign colleagues has revealed that they are mainly being studied as a new stage in the development of former summer cooperatives (dacha). In our opinion, it is rather one of the forms of pseudourbanization and imitation of Western European standards and forms of life. The cottage settlements have a higher quality of life than the surrounding villages and this causes social polarization within the urban agglomeration of the Ukrainian capital. It was revealed that the transport accessibility to Kyiv, the capital of the country, as well as the presence of natural attractors – the river, pond or forest plays an important role in their location. Conflicts have arisen over access to former public beaches and recreation areas. Currently, only residents of the respective cottage settlements have access to them, which causes social conflict with the local rural population. With the exception of four villages within the administrative boundaries of the capital, the rest are 10 to 30 kilometers away from the main motorways. The social stratification of cottage settlements has great importance. The most prestigious of them arose on the south direction 10 km from Kyiv. They are located in Koncha-Zaspa along the Dnieper river. Here their greatest concentration is revealed. Cottage settlements in the Koncha Zaspa area have become the main residence of the richest citizens of Ukraine. This led to the complete transformation of this settlement into a network of gated communities. Thus, a new structure of population distribution in the city agglomeration is gradually forming. It is presented on the map of accommodation of cottage settlements among traditional urban and rural settlements.
2.5 dimensional model of mantle heterogeneities under the Ukrainian shield according to the gradients of the velocities of seismic waves

We analyze the basic techniques for the investigation of the deep structure of the mantle and the shortcomings of the models of mantle structures derived from them. Thus, we reveal that there is no analysis of the velocity field by means of analytical transformants. Therefore, we developed and tested a new approach to define the mantle boundaries based on the calculations of the sequence of P-waves velocity derivatives. As a result, we obtain some new set of velocity gradient distributions for the principal tectonic structures of the Ukrainian Shield along the composite profile. The boundaries of the mantle discontinuities according to the velocity gradient we define in a special manner to eliminate the false anomalies and the fluctuations of the velocity curves that occur due to the conversion of the hodograph into the mean velocities. The smoothing of the velocity curve we perform with a previously defined wavelength step being equal to 50 km. We treat the calculated velocity gradient anomalies as the useful signal response above the appropriate sections, which have different velocity accelerations levels inside the upper mantle. We assume that the mantle anomalies have the same physical background (density/viscosity distributions, temperature gradients etc.) within each range with the equal acceleration value. However, the singular points determined by the inflections of the gradient curve could be the possible boundaries of additional inhomogeneities within the mantle. We calculate both the 1st and the 2nd derivatives for the velocity curves obtained. The excesses 2.5-D model of the 1-th and 2-th gradient curves (the acceleration of the gradvp itself) determine the position of the max / min anomalies of gradvp at the consolidated seismic profile within the Ukrainian Shield. Finally, we analyze in detail the distribution of velocity gradients of P-waves within the upper mantle in the depth range of 50–750 km. It results in the identification of a series of additional gradient velocity boundaries within three principal structural horizons of the upper mantle (under ~ 200–300 km, ~ 410–500 km, and ~ 600–650 km respectively).
A phronetic approach to educational design-based research: Issues and aspirations
Authors: Bardone Emanuele , Bauters Merja
Published: July 2020

This paper is a theoretical attempt to show how the Aristotelian notion of phronesis may provide a fruitful viewpoint to trigger and animate a series of discussions on educational design-based research. In particular, we focus on the overall meaning that the notions of intervention and theory can acquire. What concerns the former, phronesis helps avoid interpreting intervention as the making of an object, be it a learning environment, an application, a piece of software. Conversely, it posits that intervention can be fruitfully located within teachers’ professional judgment. The specific focus on professional judgment helps point to a different conception of “theory”, which does not revolve around the development of generalized principles informing the practice. Conversely, theory can be viewed as the effort to articulate teachers’ experiences in the form of stories “from the field”.
Resonating with reflexive design: On participatory design, narrative research and crystallization
Authors: De Vries Bregje
Published: July 2020

In this article, we further explore the idea that educational design, and subsequently educational design research, are in essence dialogical processes in which problem statements, strategies and interventions, and their implementations are realized in co-creation between different stakeholders. We elaborate on the idea of reflexive design as stated in the article of Richter and Allert (2017) by exploring three deepening thoughts on the characteristics of such dialogical design processes. First, we further relate reflexive design to the concept of participatory design to see if we can use insights from this approach on when and how co-creation can take place. Second, we explore the merits of narrative research as a way to include multiple voices in the process of reflexive design. And third, from a methodological point of view we explore the idea of crystallization as a way to collect data and validate findings within reflexive design research processes.

Teachers and researchers as co-designers? A design-based research on reading comprehension instruction in primary education
Authors: Bogaerds-Hazenberg Suzanne , Evers-Vermeul Jacqueline , Van den Bergh Huub
Published: July 2020

Insights from scientific reading research only partially resonate in Dutch teaching materials for reading comprehension, and hence in the classroom. As an attempt to bridge the gap between science and educational practice, a design-based research was conducted in which four primary school teachers translated four researcher-provided design principles into practice. In two successive design cycles, the teachers designed and implemented lessons on informational text structures, under supervision of two researchers. The aim of the study was to gain insight into the viability of the design principles and into the level of support teachers need in order to become effective co-designers. Based on data from lesson artefacts, teacher logbooks, panel interviews and lesson observations, we found that the teachers experienced several implementation difficulties. These difficulties were partially due to the fact that there was a tension between two design principles, and that one design principle needed refinement. However, in most cases, the implementation difficulties could be explained by teachers’ limited pedagogical content knowledge. As a result, the teachers needed a high level of support, especially in text selection and revision. Teacher beliefs and habits also interfered with the implementation of the design principles, especially when it came to the importance of working with authentic texts, and teachers’ views on effective modeling.Our study raises questions about the feasibility of equal participation of researchers and teachers at the start of a DBR project, but also shows how DBR can successfully contribute to teacher professionalization if researchers provide adequate support throughout the design process.
DOUBLE MOVEMENTS DALAM TAFSIR AL-MISHBAH

Published: July 2020

Artikel ini mendiskusikan gagasan hermeneutik double movement Fazlur Rahman dalam menafsirkan Alquran. Terdapat kalangan yang menyetujui dan menolaknya. Artikel  ini  menfokuskan pada penelusuran terhadap sikap dan  aplikasi  M. Quraish Shihab terhadap double movement dengan pendekatan content analisys. Objek material riset ini adalah penafsiran Shihab terhadap ayat hukum yang terdapat dalam Tafsir Al-Mishbah, dimana Rahman juga membahas ayat tersebut. Tulisan ini menemukan bahwa secara prinsip Shihab meresepsi positif terhadap keberadaan hermeneutik double movement, dijadikan pendekatan dalam penafsiran Alquran. Namun, ada rambu yang mesti dipatuhi dalam menggunakannya yaitu dengan tidak menafikan keberadaan redaksi ayat, tidak menghapus aspek hukum yang terkandung dalam Alquran, dan memerhatikan ayat secara holistik. Shihab menolak penggunaan hermeneutik dalam menafsirkan Alquran jika batasan-batasan tersebut diabaikan. Berdasarkan prinsip tersebut, ditemukan  variasi sikap  Shihab. Dari keempat ayat yang ditelusuri dalam kajian ini; dua ayat  ditafsirkann oleh Shihab dengan menggunakan double movement, dan dua lainnya ditafsirkannya tanpa menggunakan double movement.
