Published: February 2021

The term ‘Big Data’ has been coined to refer to the gargantuan bulk of data that traditional data handling techniques cannot deal with. Big Data is still a novel concept, and in the following literature, we intend to elaborate on it palpably. It commences with the concept of the subject in itself, along with its properties and the two general approaches to dealing with it. Big Data provides an opportunity for educational Institutions to use their Information Technology resources strategically to improve educational quality, guide students to higher completion rates, and improve student persistence and outcomes. This paper explores the attributes of big data that are relevant to educational institutions, investigates the factors influencing the adoption of big data and analytics in learning institutions, and seeks to establish the limiting factors hindering the use of big data in Institutions of higher learning. A survey research design was adopted in conducting this research, and the Questionnaire was the instrument employed for data collection.

Published: February 2021

As the usage of the internet grows, more and more information is obtained, thus presenting challenges, especially for users and website owners. Website users often have difficulty finding products or services that are relevant to their needs caused by abundant amounts of products and services delivered on a website. Website owners often find it difficult to convey information about the right products and services to certain target users. Based on the problem given above, we can conclude that a recommendation system approach that can improve personalization on their website is needed. The recommendation system approach must be able to provide navigation on the website to make it more adaptive towards the interests and information needed by the user. This study uses Association Rules formed from Microsoft web access log data by finding visitor patterns based on frequently visited web site pages. From the results of the research conducted, the performance of the method used has a precision value of 0.896, 0.058 recall, and F-measure 0.104. Whereas the measurement of the accuracy value resulted in a performance recommendation of exactly 3%, an acceptable rate of 87%, and 10% incorrect. This research shows that the Association Rules method can increase the effectiveness of website personalization to provide relevant information recommendations for visitors. For further research, it can concentrate on improving existing methods thus website personalization becomes more adaptive.
The Concept of Fitrah for Children in Ibn Katsir's Qur'an Exegesis: A Pedagogical Implication in Early Childhood Islamic Education
Authors: Purnama Sigit , 'Aziz Hafidh , Nurhusna Lu’lu’ , Ulfah Maulidya
Published: February 2021

The debate in child development is the factors that influence development, such as genetic factors, heredity, or environmental factors. Filling the room for dialogue and discourse on the conflict of these two causes, Islam offers an alternative to the Qur'an fitrah definition. This study aims to reveal the concept of child fitrah according to Ibn Katsir in the Tafsir Al-Qur'an al-'Aẓhim and the pedagogical implications in early childhood Islamic education. This study uses qualitative research methods with a descriptive-analytic approach. The data were collected through documents and analyzed using the Creswell model analysis technique. The results showed that the concept of human nature (fitrah), according to Ibn Katsir, is based on good innate potential, i.e., Tawheed or religious nature. Therefore, education has to maintain this nature as a positive external agent by referring to Allah's guidance through the Prophet's revelations and examples. It then manifests by observation, literacy, modeling, and reasoning in the learning activity. In the educational process, these efforts can be: 1) Wisdom, which can be interpreted as literacy and modeling. The activities can be memorization and recitation with modeling from adults or teachers; 2) Mau'idhoh, oral transmission method to convey messages, reasoning, and even warnings; 3) If necessary, an excellent Jidal method can be used. Thus, the potential of Fitrah is transformed into a necessity for humans to fulfill their "primordial promise" to Allah. Finally, this study provides a basis for pedagogical practice based on the concept of fitrah according to Ibn Katsir in the implementation of early childhood Islamic education.

The article is devoted to the problem of information protection generated by a glide path beacon of the PRMG format for providing instrumental approach of aircraft for landing. To en-sure a safe approach, the radio beacon landing system forms a descent trajectory in space - a glide path. A developed multilevel control system is designed to ensure the integrity of the land-ing system by continuous monitoring of the position of a given glide path and the steepness of the indicated glide path parameter. However, during flight tests of a glide path beacon (GPB), a false glide path is sometimes detected in the area of the landing system, which naturally vio-lates its integrity. The article shows the reason for this phenomenon - a violation of the multi-plicity of the heights of the suspension of the radiating elements of the GPB antenna array. Flight measurements data of the glide path zone at the airfield in the foothills are given. The experimental results confirm the theoretically found regularities in the behavior of the informa-tion parameter of the glide path beacon in a wide sector of angles. Recommendations are pro-posed for maintaining the integrity of the landing system

The study examines the technology of forming a high-informative digital image of the ob-served time signal of an automated control system (ACS). Formation of the signal image in-cludes the stage of displaying the signal on the time-frequency representation, obtaining the time-frequency image of the signal, the stage of two-dimensional digital filtering, the stage of formation of high-informative components of the signal image. The resulting digital image of the observed ACS signal represents the generated high-informative input data for further solv-ing a wide range of different problems using machine learning technologies and deep neural networks in the ACS of industrial systems. A wide range of tasks using the generated digital im-age of the signal implies, for example, the analysis of process behavior and identification of anomalies in the process of ACS, the implementation of diagnostic algorithms of technical equipment in the ACS, the detection of changes in the dynamics of the process of ACS under the influence of information attacks
Changing the World Through Poetry: Confessions, Poems and Banners of Adam Borzič
Authors: Kittlová Markéta
Published: February 2021

This study focuses on Adam Borzič, one of the most distinctive contemporary Czech poets. The study contextualises his work within current Czech poetry but also examines his other work that is not strictly classified as art as though it were cultural work with avant-garde features. It investigates four volumes of Borzič’s work in terms of the changes in the author’s creative gesture, which expands from his conviction that the world is at a turning point and the avant-garde longing to change the world by poetry. In the four volumes of Borzič’s poetry (written so far), this gesture is embodied through delicately intimate, acutely physical, or even gigantically all-embracing positions, where he employs motives of the heart, head, hand and mouth. The study attempts to evaluate the change in Borzič’s work in the lightof T. S. Eliot’s understanding of the social role of poetry and avant-garde longing to change reality through art. The Czech poet, Adam Borzič, is one of the most distinctive figures of the current Czech literary scene. His poetry is distinct because of its unique gesture andalso represents a strong current in the poetry production of the past decade with its emphasis on the social function of poetry7 and the poet’s role as somebody who should nurture the world through his/her work or even change it. This study attempts to portray Borzič’s work as focused on the mentioned topics and related issues of the end of the first decade of the twenty-first century and renew interest in them, contextualise his work within current Czech poetry but also investigate his other work, which is not strictly artistic but which possesses some avant-garde features.
Nonhuman Primates Satisfy Utility Maximization in Compliance with the Continuity Axiom of Expected Utility Theory
Authors: Ferrari-Toniolo Simone , Bujold Philipe M. , Grabenhorst Fabian , Báez-Mendoza Raymundo , Schultz Wolfram
Published: February 2021

Expected Utility Theory (EUT), the first axiomatic theory of risky choice, describes choices as a utility maximization process: decision makers assign a subjective value (utility) to each choice option and choose the one with the highest utility. The continuity axiom, central to Expected Utility Theory and its modifications, is a necessary and sufficient condition for the definition of numerical utilities. The axiom requires decision makers to be indifferent between a gamble and a specific probabilistic combination of a more preferred and a less preferred gamble. While previous studies demonstrated that monkeys choose according to combinations of objective reward magnitude and probability, a concept-driven experimental approach for assessing the axiomatically defined conditions for maximizing utility by animals is missing. We experimentally tested the continuity axiom for a broad class of gamble types in 4 male rhesus macaque monkeys, showing that their choice behavior complied with the existence of a numerical utility measure as defined by the economic theory. We used the numerical quantity specified in the continuity axiom to characterize subjective preferences in a magnitude-probability space. This mapping highlighted a trade-off relation between reward magnitudes and probabilities, compatible with the existence of a utility function underlying subjective value computation. These results support the existence of a numerical utility function able to describe choices, allowing for the investigation of the neuronal substrates responsible for coding such rigorously defined quantity.

SIGNIFICANCE STATEMENTA common assumption of several economic choice theories is that decisions result from the comparison of subjectively assigned values (utilities). This study demonstrated the compliance of monkey behavior with the continuity axiom of Expected Utility Theory, implying a subjective magnitude-probability trade-off relation, which supports the existence of numerical utility directly linked to the theoretical economic framework. We determined a numerical utility measure able to describe choices, which can serve as a correlate for the neuronal activity in the quest for brain structures and mechanisms guiding decisions.
Dynamic Simulation, Parameter Optimization, and Control of a Reactive Distillation Column for Production of Isopropanol via Propylene Hydration
Authors: Feizi-Afshar Bahareh , Farzi Ali
Published: February 2021

In this study, a reactive distillation column for production of isopropanol was investigated. Firstly, a dynamic model was developed for the process. The model of the process was then programmed, and the process simulated using a base case obtained from the literature. Results showed that distillate contained more than 58 mol% propylene-free

isopropanol. In the next step, optimization of some operating variables was performed to

maximize concentration of isopropanol in distillate with condenser temperature as constraint, which was considered to be above the freezing point of water. Several simulations were performed by changing operating parameters, and finally optimum isopropanol content in distillate was obtained above 58 mol%. Results of using classic controllers showed that PID controller had the best performance for both condenser temperature set-point tracking and disturbance rejection.
Afekt i konwencja – budowanie przestrzeni widzenia
Authors:   Uniwersytet Warszawski, Nabiałek Magda
Published: February 2021

The article discusses the coexistence of two phenomena in the drama of the second half of the 19th century and the early 20th century. By combining affect and convention, the author seeks to point out the dramatic use of the forgotten plot schemes, characters, and construction solutions, which still remain strongly preserved in the cultural memory of the viewers. These were highly characteristic of the comedy dell’arte, the Russian balagan, which was at the time regaining its popularity in Italy, as well as of the Polish fairy tale. The authors used them in order to evoke in the viewer a certain kind of affectation. This, in turn, allowed them to build ties with the audience based on completely new rules of participation, which gave rise to the theatrical phenomena characteristic of the second half of the 20th century.

Siła sprawcza afektu. O balladzie Czaty Adama Mickiewicza
Authors:   Uniwersytet w Białymstoku, Januszkiewicz Agnieszka
Published: February 2021

The article analyzes the ballad Czaty by Adam Mickiewicz, which has so far received little critical attention. If it was discussed, though, the reason was merely its experimental verse form of the anapaest and the work’s stylistic merit. Aiming to re-interpret Mickiewicz’s poem, the author of the article concentrates on the narratorial voice and the connections between the literary characters (the voivode, his young wife, the lover, and the voivode’s Cossack servant-Nauman). She also underscores the driving force behind the unfolding events. The reading reveals that the characters act upon sudden affective reactions which they can hardly control.

Goal – the article is devoted to the analysis of corporate social responsibility as a social, economic and legal phenomenon. The article presents the results of a theoretical and empirical sociological study of the features of the influence of organizational strategies of corporate social responsibility on the staff identity formation of companies and organizations in St.-Petersburg and the North‑West region of Russia. Research methodology – the authors argue that the development of ideas related to the need to create their own strategies for corporate social responsibility was significantly influenced by the practices of Western European firms and companies that began active cross‑border cooperation with Russian companies in the late XX – early XXI centuries. Score/results – the results of the study proved that socially responsible actions of Russian or foreign companies help to improve the internal organizational climate, improve the attitude of employees to their company and staff identity formation. Implementation of corporate social responsibility practices also solves complex organizational problems, for example, such as: increasing the level of staff loyalty and reducing staff turnover. Originality/value – the study showed that Russian companies are still lagging behind the West European companies in the field of creating and implementing effective corporate social responsibility strategies. But some examples show that Russian companies are already actively involved in the development of corporate social responsibility of a new, modern type.

The inadequate corpus luteum
Authors: Duncan W Colin
Published: February 2021

The corpus luteum is the source of progesterone in the luteal phase of the cycle and the initial two-thirds of the first trimester of pregnancy. Normal luteal function is required for fertility and the maintenance of pregnancy. Progesterone administration is increasingly used during fertility treatments and in early pregnancy to mitigate potentially inadequate corpus luteum function. This commentary considers the concept of the inadequate corpus luteum and the role and effects of exogenous progesterone. Progesterone supplementation does have important beneficial effects but we should be wary of therapeutic administration beyond or outside the evidence base.

Lay summary

After an egg is released a structure is formed on the ovary called a corpus luteum (CL). This produces a huge amount of a hormone called progesterone. Progesterone makes the womb ready for pregnancy but if a pregnancy does not happen the CL disappears after 12–14 days and this causes a period. If a pregnancy occurs, then the pregnancy hormone (hCG) keeps the CL alive and its progesterone supports the pregnancy for the next 6–8 weeks until the placenta takes over and the corpus luteum disappears. That means that if the CL is not working correctly there could be problems getting pregnant or staying pregnant. If a CL is not producing enough progesterone it usually means there is a problem with the growing or releasing of the egg and treatment should focus on these areas. In IVF cycles, where normal hormones are switched off, the CL does not produce quite enough progesterone before the pregnancy test and extra progesterone is needed at this time. In recurrent or threatened miscarriage, however, there is not any evidence that the CL is not working well or progesterone is low. However, there is benefit in taking extra progesterone if there is bleeding in early pregnancy in women with previous miscarriages. This might be because of the effects of high-dose progesterone on the womb or immune system. As changes to the hormone environment in pregnancy may have some life-long consequences for the offspring we have to be careful only to give extra progesterone when we are sure it is needed.
ВИЗНАЧЕННЯ ПРАВОВОГО СТАТУСУ ГРЕКО-КАТОЛИЦЬКОЇ ЦЕРКВИ У ПОЛЬСЬКІЙ ДЕРЖАВІ (1919–1925 рр.)
Authors: Людмила Дрогомирецька Олег Єгрешій
Published: February 2021

У науковій статті автори намагаються визначити правовий статус Греко-католицької Церкви у Польській державі упродовж 1919–1925. Розкривається репресивна політика польських органів влади проти греко-католицького духовенства впродовж другої половини 1919 р. Вище духовенство ГКЦ рішу­че протестувало проти арештів священнослужителів. У статті зазначається, що репресії пояс­нюють­ся державницькою позицією значної частини священнослужителів. Більшість отців ГКЦ підтримали бойкот перепису населення 1921 р. і бойкот виборів до польського сенату і сейму 1922 р. у Галичині. Священики усвідомлювали, що ці заходи організовані задля узаконення польської прина­леж­ності Східної Галичини. 

Відзначено, що  спроба станиславівського єпископа Г. Хомишина нормалізувати польсько-українські відносини в Галичині шляхом переговорів між польськими і українськими ієрархами не була підтримана більшістю священнослужителів. У статті акцентовано увагу на негативній реакції поль­сь­ких урядових структур до дипломатичних зусиль митрополита Андрея Шептицького лобіювати україн­ські інтереси у окремих країнах Європи та Америки. Згадується, що польські власті прагнули забо­ронити А. Шептицькому повернутися до Галичини, домогтися від нього письмого визнання лояльного ставлення до польської держави. Розглядався варіант  відкликання його з митрополичого престолу під приводом надання йому високої посади у Римі. Переслідування українського ієрарха викликало різко негативний резонанс серед загалу греко-католицького духівництва та вірних.

Відзначається, що Конкордат, підписаний  1925 р. закріпив правовий статус ГКЦ та нову мо­дель церковно-державних відносин у Другій Речі посполитій, яка мусила забезпечувати політичну лояль­ність ієрархії та духовенства відносно польської держави. Аналіз дотримання/недотримання греко-католицькими священиками умов Конкордату стане предметом подальших наукових досліджень колективом авторів.

Ключові слова: правовий статус, Греко-католицька Церква, Митрополит А. Шептицький, Кон­кордат, репресії духовенства.

У статті висвітлюються контакти Пантелеймона Куліша з Галичиною, що охоплюють період від першого приїзду українського письменника і громадського діяча до Львова влітку 1858 р. і до переходу на державну службу наприкінці 1864 р. та появи останніх публікацій у часописах “ранніх” народовців на початку 1865 р. П. Куліш відіграв особливу роль в утвердженні української національної ідеї серед галичан, особливо в 1867 р. – на початку 1870-х рр., підтримував діяльність місцевих народовців. Значну увагу звернено на листування П. Куліша з Я. Головацьким після знайомства в 1858 р., його взаємини з ліде­ра­ми народовців Д. Танячкевичем і К. Климковичем, русофілом Б. Дідицьким та ін.

Ку­ліша – як нові, так і раніше опубліковані, насамперед з альманаху “Кіевлянинъ” 1840 і 1841 рр. та пе­тербурзького журналу “Основа” (1861–1862 рр.) – регулярно друкувалися в народовській пресі у Львові – часописах “Вечерниці” (1862–1863 рр.), “Мета” (1863–1865 рр.) і “Нива” (1865 р.). Водночас П. Куліш друкувався в русофільських виданнях – газеті “Слово” і літературному збірнику “Галичанинъ”, що на початку 1860-х рр. проявляли інтерес до нової української літератури. Кулішеві зв’язки з галицькими діячами перервалися після його призначення російським чиновником у Варшаві в умовах посилення антиукраїнських репресій царизму та внутрішньої кризи в діяльності галицьких народовців. З новою силою інтерес П. Куліша до Галичини проявився з 1866 р.

Ключові слова: Пантелеймон Куліш, український діяч, Галичина, контакти, часопис, народовці, русофіли.

Bifunctional cellulases with β-glucosidase (Bgl1), exoglucanase (Exo5), and carbohydrate-binding modules (CBMs) from Caldicellulosiruptor saccharolyticus were fused to yield several recombinant plasmids, Bgl1-CBM-Exo5, Bgl1-2CBM-Exo5, and Bgl1-3CBM-Exo5. The fused enzymes possessed both β-glucosidase and exoglucanase activities and were used to improve the degradation efficiency of lignocellulosic biomass. The optimal temperature of Bgl1-3CBM-Exo5 was 70 °C, which was the same as Bgl1, and the optimal temperature of the other two enzymes was 80 °C, which was the same as Exo5. The optimal pH of fused enzymes was 4 to 5, the same as Exo5, but the optimal pH of Bgl1 was 5.5. Compared with Bgl1-CBM-Exo5 and Bgl1-2CBM-Exo5, the hydrolysis efficiency of Bgl1-3CBM-Exo5 on sodium carboxymethyl cellulose (CMC-Na) was increased by 67% and 50%, respectively. The activities of these enzymes on CMC-Na were increased by 128 to 192% when 10 mM MnCl2 was added. Filter paper, microcrystalline cellulose (MCC), steam-pretreated rice straw, rice straw, and wheat straw were efficiently degraded by these fused enzymes. Specific activities of the fusion enzymes on MCC reached 34.4 to 76.4 U/μmol. The results indicated that bifunctional cellulases fused with CBMs were functional on cellulosic biomass, and CBMs contributed to further deconstruction of MCC and other natural substrates.

Published: February 2021

Objetivo: objetivou-se comparar as prevalências e os fatores associados à realização de mamografia de acordo com dois critérios em vigência no Brasil.Métodos: estudo transversal, de base populacional, com mulheres entre 40 e 74 anos de Rio Grande, RS, Brasil. A cobertura de mamografia foi avaliada: 1) rastreamento anual para mulheres entre 40 e 74 anos; 2) rastreamento bienal para mulheres entre 50 e 69 anos. Os dados foram analisados por regressão de Poisson.Resultados: participaram do estudo 413 (critério 1) e 246 (critério 2) mulheres. A cobertura de mamografia pelo critério 1 foi de 49,4% (IC95% 43,8 a 55,0), oscilando de um quarto para as que não consultaram um médico no último ano até dois terços para aquelas com maior escolaridade. Segundo o critério 2, a cobertura foi de 65,5% (IC95% 59,2 a 71,7), indo de um terço entre as que não consultaram um médico no último ano a três quartos entre as obesas.Conclusões: a cobertura de mamografia diferiu conforme o critério empregado. Maior nível socioeconômico e ter consultado com médico no último ano foram os fatores mais associados, independentemente do critério.
El pasado como metástasis: archivo, memoria y colonialismo en la poética de Gianikian y Ricci Lucchi
Authors: Morales Sosa Isdanny
Published: February 2021

El presente artículo examinará cómo podemos pensar las metodologías cinematográficas de la pareja Gianikian-Ricci Lucchi en relación con un cine político a partir de tres filmes representativos, Del Polo al Ecuador (Dal Polo all’Equatore, 1986), Imágenes del Oriente: turismo de vándalos (Immagini dell’Oriente: turismo da vandali, 2001) y País bárbaro (Pays barbare, 2013). Se analizará su relevancia, principalmente del trabajo con material de archivo, para la generación de un tipo de cine que pone en evidencia los colonialismos y fascismos del pasado a través de un ejercicio de memoria que hurga, no en el relato de la gran Historia, sino en rostros concretos, ademanes, prácticas y objetos no solo de las víctimas, sino también de los victimarios, con lo cual se configura una poética que versa sobre “la pretérita densidad de nuestro presente”.
Algunas aproximaciones a la relación entre el arte pictórico y la práctica educativa: descripción de un sentimiento pedagógico
Authors: Prada Arévalo Mauricio
Published: February 2021

El presente artículo indaga a partir de algunos referentes teóricos, experiencias pedagógicas y reflexiones diversas, sobre la relación existente entre el arte pictórico y la práctica educativa en la formación y la cultura humanas. Esta conexión se ha evidenciado desde los orígenes de la civilización y ha llegado, después de numerosas transformaciones, al escenario educativo contemporáneo, el aula de clases y el currículo. En ella han sido relevantes muchos aspectos de índole histórica, cultural y teórica. Lejos de ser un tema superado, elvínculo que mantiene el arte pictórico con la práctica pedagógica es un campo en donde germinan consideraciones filosóficas y experiencias didácticas que pueden colaborar en la necesaria transformación de la educación en sus distintos niveles y ámbitos. Aquí se describirán algunos de esos elementos y experiencias con sus diversas consideraciones académicas, usos didácticos y logros pedagógicos.
El actor desde la psicología de Stanislavski y la intervención social de Boal
Authors: Jiménez Pamela
Published: February 2021

Se propone establecer un análisis comparativo sobre la visión del actor desde la Memoria de las Emociones de Stanislavski y del Teatro del Oprimido de Boal. Ambos autores han propuesto teorías que se han vuelto modelos a seguir, en cuanto a su corpus teórico teatral y a su manera de ver y vivir el teatro contemporáneo. Han trascendido sus disciplinas, permitiendo establecer un diálogo entre la psicología, la pedagogía –a través de la intervención socialyel arte. Los dos ofrecieron la idea de un nuevo actor, que se permite explorar y compartir en la escena porque trabaja con y para el ser humano. Han gestado la posibilidad de que el espectador logre un proceso catártico o ejercite una posible modificación del mundo real; que habite vidas que no son suyas o que provoque una reacción activa sobre su entorno.
Entre la crítica sociopolítica y la utopía artística: el Colectivo de Acciones de Arte (CADA), 1979-1985
Authors: Marchena Sanabria Jorge
Published: February 2021

El presente ensayo tiene como fin elaborar un breve recorrido por las obras del Colectivo de Acciones de Arte (CADA), presentadas en Chile entre 1979 y 1985; momentos en que la dictadura de Augusto Pinochet se pretendía naturalizar. El CADA destaca, no solo como un ejemplo chileno de arte contemporáneo, sino por su oscilación entre una propuesta de vanguardia –acorde con las tendencias internacionales de la época– y la denuncia política. Precisamente, ante la represión y persecución del régimen y el apagón cultural que estaba experimentando el país, el Colectivo se enfocó en el rescate de la memoria y en la  transmisión subrepticia de críticas y mensajes de resistencia. Por ello se analiza la visión que se ha construido en torno a este grupo, rozando con la idealización; proceso que no ha sido adrede. Para la elaboración de este trabajo, se retomaron diversas posturas teóricas en torno al arte contemporáneo, la revisión de artículos de revistas de la época, bibliografía y otros materiales que han sido preservados en torno a las obras que realizó el CADA.
El arte contemporáneo como reflexión social: una aproximación a la obra de Regina José Galindo
Authors: Otárola Guevara Marcela
Published: February 2021

El arte contemporáneo emerge en el siglo XX y se destaca por el cambio de un paradigma, derivado de una nueva forma de vinculación entre el artista y la sociedad. Para apreciar tal relación, se procede a analizar cualitativamente algunas obras de una exponente de este movimiento, Regina José Galindo, a partir de un cuestionamiento y posterior interpretación sobre las razones que han originado sus producciones. Tal ejercicio requirió estudiar premisas teóricas procedentes de la sociología, la filosofía y la historia del arte. Las piezas seleccionadas refieren a temas asociados a la memoria, la mujer y las relaciones de poder. Además, muestran la empatía y la apropiación espacial como mecanismos de articulación social y revelan los alcances de sus propuestas: exponer a las personas oprimidas, interpelar al espectador y conceder valor al contexto.
Entre el mercado global del arte contemporáneo y la muerte: la obra de Teresa Margolles
Authors: Mora Solano Sindy
Published: February 2021

En este artículo se analiza la obra de la artista mexicana Teresa Margolles y se expone la tesis de que su trabajo se ha posicionado en el mercado global del arte, promovido por la paradoja permisiva de la institucionalidad del arte contemporáneo. Mediante este mecanismo, Margolles ha exportado, desde la periferia hasta el centro, un arte que enfatiza en las imágenes de violencia y de muerte, además de convertirlas en objetos exóticos de exposición en museos europeos y estadounidenses. En el texto, se analizan tres de sus obras: ¿De qué otra cosa podríamos hablar? (2009), La Promesa (2012) y El Testigo (2014).

Soft magnetic metal amorphous nanocomposite alloys are produced through rapid solidification and thermal annealing yielding nanocrystals embedded within an amorphous precursor. Similar free energies in Co‐rich and FeNi‐based alloy systems result in multiple nanocrystalline phases being formed during devitrification. Studies of multi‐phase crystallization processes have been reported for Co‐rich alloys but relatively few have investigated FeNi‐based systems. A detailed characterization of compositional partitioning and microstructure of an optimally annealed FeNi‐based MANC (Fe70Ni30)80Nb4Si2B14 alloy is presented through complementary high‐resolution transmission electron microscopy (HRTEM) and atom probe tomography (APT). HRTEM demonstrates orientation relationships between FCC and BCC nanocrystals, suggesting heterogeneous nucleation of nanocrystals in the amorphous matrix or a cooperative mechanism of nucleation between BCC and FCC nanocrystallites. APT results show evidence for (i) the segregation of Fe and Ni between nanocrystals of different phases, (ii) B partitioning to the amorphous phase, and (iii) an Nb‐enriched shell surrounding nanocrystals.
Probing surfaces and interfaces in complex oxide films via in situ X-ray photoelectron spectroscopy

Published: February 2021

Emergent behavior at oxide interfaces has driven research in complex oxide films for the past 20 years. Interfaces have been engineered for applications in spintronics, topological quantum computing, and high-speed electronics with properties not observed in bulk materials. Advances in synthesis have made the growth of these interfaces possible, while X-ray photoelectron spectroscopy (XPS) studies have often explained the observed interfacial phenomena. This review discusses leading recent research, focusing on key results and the XPS studies that enabled them. We describe how the in situ integration of synthesis and spectroscopy improves the growth process and accelerates scientific discovery. Specific techniques include determination of interfacial intermixing, valence band alignment, and interfacial charge transfer. A recurring theme is the role that atmospheric exposure plays on material properties, which we highlight in several material systems. We demonstrate how synchrotron studies have answered questions that are impossible in lab-based systems and how to improve such experiments in the future.
