Übersetzung als Erinnerung
Authors: Harsch Georg Felix
Published: March 2021

In den 1950er-Jahren spielten übersetzte Sachbücher eine Schlüsselrolle bei der Etablierung von Diskursräumen zu den NS-Verbrechen in der BRD und in der DDR. Die Übersetzung war für eine kleine Gruppe von Akteur*innen ein wichtiges Instrument, mit dem sie explizites Wissen in den deutschen Diskurs einschreiben wollten. Georg Felix Harsch beschreibt, wie dieser Sprachtransfer nicht-nationalsozialistische deutsche Sprachformen zum NS-Massenmord entwickelte, wie diese Sprache marginalisiert wurde und wie Übersetzer*innen dennoch Grundlagen für einen ehrlich erinnernden Diskurs schafften, der sich überwiegend erst Jahrzehnte später entfalten konnte.
Hoffnung auf eine bessere Vergangenheit
Authors: Kibel Jochen
Published: March 2021

Unter dem ungewissen Erwartungshorizont spätmoderner Gesellschaften treten verschiedene Vorstellungen kollektiver Identität in Konflikt. Jochen Kibel zeigt: Im Streit um das Neue Museum in Berlin und das Militärhistorische Museum in Dresden artikulierten sich unterschiedliche Kollektivierungsdiskurse, in denen die Vergangenheit nach den Anforderungen der Gegenwart umgeformt wurde. Der retrospektive Blick gewährt damit immer auch die prospektive Hoffnung auf eine bessere Vergangenheit. Die dynamischen Verhältnisse der Gegenwart bringen schließlich eine Form reflexiver Identitätsbildung hervor, in der auch die Fähigkeit anhaltender Selbstkritik in der Vergangenheit ›wiedergefunden‹ wird. Die Vorstellung einer wandlungsfähigen Identität gewährleistet dann ein Gleichbleiben im Strom der Zeit, durch beständige Kurskorrekturen.
Gefragt durch Andere

Published: March 2021

Nichts überdauert ohne Wiederholung - nichtsdestotrotz, die Essays in diesem Buch zeigen, dass das Bestehende in seiner Wiederholung verändert werden kann, es sogar verändert werden muss. Die Texte unternehmen kritische Beschreibungen des Bestehenden. Sie behandeln das Ausbeutungssystem des Kapitalismus, die damit verbundene Unterdrückung und Überforderung des Subjekts und nicht zuletzt die Zurückweisung von Identität als Konzept der Privilegierten, das notwendigerweise Ausgrenzung erzeugt und verstetigt.
Ewa Partum's Artistic Practice
Authors: Majewska-Güde Karolina
Published: March 2021

Polish-born artist Ewa Partum is considered a pioneer of Central-Eastern European feminist art produced within the conceptual idiom. Her work can also be divided chronologically into Polish (1965-82), West Berlin (1982-1989) and transnational (from 1989) periods. Karolina Majewska-Güde articulates the historical alterity of Ewa Partum's works in their various locations and the specificity of the positions from which Partum's art was interpreted and disseminated. At the same time, the book engages with the art histories of the Central and Eastern European neo-avant-gardes focusing on the issue of narrative strategies of CEE art history.
Theologie und Normen im Wandel
Authors: Abd-Elsalam Ahmed M. F.
Published: March 2021

Nicht alles, was wir als religiös sehen oder verstehen, hat tatsächlich religiöse Anfänge. So wurden altarabische Normen und Werte frühzeitig in den Islam übernommen und in einem langen Transformationsprozess islamisiert. Ahmed M. F. Abd-Elsalam befasst sich mit einer sehr frühen Entstehungsphase des Islams, in der die Grenzen zwischen altarabischen säkularen Normen und entstehenden islamischen religiösen Normen nicht klar definiert waren. Indem er säkulare und rationale Urfundamente islamischer Normen und ihren Einfluss auf die islamische Theologie beleuchtet, wird der Weg für eine umfassende Reformation islamischen Denkens geebnet und eine neue Perspektive, den Islam zu lesen und zu verstehen, eröffnet.
Thinking of Space Relationally
Authors: Gao Xiaoxue
Published: March 2021

Since the relational turn, scholars have combated methodological universalism, nationalism, and individualism in researching social-spatial transformations. Yet, when leaving the gaps between the traveling and local epistemic assumptions unattended, engaging relational spatial theories in empirical research may still reproduce established theoretical claims. Following the sociology of knowledge tradition and taking Critical Realism as a meta-theoretical framework, Xiaoxue Gao takes relational spatial theories as traveling conceptual knowledge and develops meaningful and context-sensitive ways of engaging them in studying the complex urban phenomenon in China. She offers conceptual elucidations and methodological roadmaps, which leap productively from employing plural causal hypotheses to generating effect-based explanations for locally observable events. They are exemplified by manifold interrogations of Beijing's Artworld as a conjuncture of particular events.

Sie gestalten mit ihren unterschiedlichen Handlungen die soziale und emotionale Atmosphäre und tragen zur gelungenen oder misslungenen Erinnerung an die Vernissage bei. Durch die kultursoziologisch-empirische Betrachtungsweise des Rituals der Vernissage werden umfassend Erkenntnisse zu diesem sozialen Phänomen präsentiert.
Nachhaltige Lebensführung
Authors: Görgen Benjamin
Published: March 2021

Vor dem Hintergrund der sozial-ökologischen Krisen der Gegenwart ist es von entscheidender Bedeutung, nachhaltigere Formen der Lebensführung zu realisieren. Auch wenn sich diese Einsicht in den letzten Jahren zunehmend verbreitet, bleibt weiterhin umstritten, wie dieses Ziel erreicht werden kann. Bildung und »aufgeklärter Konsum« allein werden nicht ausreichen, wie immer wieder deutlich wird. Aber welche Faktoren sind dann von Bedeutung und wie entsteht nachhaltige Lebensführung in der alltäglichen Praxis? Benjamin Görgen geht diesen Fragen nach und nimmt dazu die Realisierungsbedingungen nachhaltiger Lebensführung am Beispiel gemeinschaftlicher Wohnprojekte im urbanen Raum differenziert in den Blick.
Fernbeziehungen
Authors: Scherrer Madeleine
Published: March 2021

Fernbeziehungen reproduzieren nicht nur normalisierte Vorstellungen von Intimität, sondern stellen sie zugleich infrage. Madeleine Scherrer erforscht, wie Frauen in Fernbeziehungen von vergeschlechtlichten Erfahrungen und Erwartungen berichten. Anhand theoretischer Ansätze zu Raum und Medialität zeigt sie auf, wie Fernbeziehungen als produzierte und sich überlagernde mediale Zwischenräume fungieren. Mit Rückgriff auf Karen Barads Methode der Diffraktion dekonstruiert sie normalisierte Intimitätsvorstellungen und hegemoniale dualistische Denkweisen.

Estudio Comparativo de Tres Estrategias de Control para la Regulaci´on de Frecuencia de una Micro Red en Operaci´on Aislada
Authors: Pineda Muñoz Edwin Alexis , Gauthier Selleir Alain
Published: March 2021

Contexto: La reducci´on de combustibles f´osiles, la necesidad de disminuir las emisiones de di´oxido de carbono (CO2) en el planeta y el inter´es por garantizar una seguridad energ´etica ha incrementado la investigaci´on en la producci´on de energ´ıa el´ectrica utilizando fuentes de energ´ıas renovables incorporadas a micro redes ´o MGs (Microgrids). Este panorama presenta desaf´ıos t´ecnicos que deben ser cubiertos para garantizar niveles de confiabilidad adecuados.

M´etodo: Este estudio compara tres estrategias de control basadas en el control predictivo del modelo ´o MPC (Model Predictive Control), el control ´optimo LQ-Servo (Linear Quadratic Servo) y el control proporcional integral ´o PI, con el objetivo de regular la frecuencia frente a incertidumbres en la carga y perturbaciones ambientales, considerando un modelolineal aislado de microrred que incluye generadores convencionales y renovables, dispositivos de almacenamiento de energ´ıa y cargas.

Resultados: Las simulaciones de la micro red en operaci´on aislada, en presencia de perturbaciones de viento, carga y potencia solar, muestran un mejor desempe˜no bajo diferentes escenarios de los controladores MPC y LQ-Servo con respecto a las caracter´ısticas din´amicas que presenta la desviaci´on de frecuencia y la se˜nal de control.

Conclusiones: La estrategia de control ´optimo LQ-Servo, poco investigada en micro redes, se presenta como una opci´on viable a considerar en el dise˜no de controladores secundarios de micro redes en operaci´on aislada, debido a las caracter´ısticas de desempe˜no mostradas en la regulaci´on de frecuencia.

Conceptualización y gravedad semántica en la construcción de explicaciones científicas en la clase de fisicoquímica: un estudio de caso
Authors: Cutrera Guillermo , Massa Marta , Stipcich Silvia
Published: March 2021

La construcción y la comprensión de las explicaciones científicas escolares constituyen dos propósitos centrales en la alfabetización científica. La misma requiere que los estudiantes puedan participar en discursos y prácticas científicas escolares. Las prácticas de enseñanza, en este contexto, adquieren centralidad para la adquisición de nuevas formas de saber, hacer y hablar ciencia por los estudiantes. Con estas consideraciones en este artículo se analiza el discurso docente de una futura profesora de Química cuando trabaja en la construcción conjunta con los estudiantes de explicaciones correspondientes a un fenómeno cotidiano. El discurso es interpretado desde los niveles de conceptualización de la materia y la noción de gravedad semántica. La investigación se enmarca en una perspectiva cualitativa, desde el enfoque de estudio de casos. Se elabora un sistema de categorías asociado a cada una de las dimensiones de análisis -niveles de conceptualización de la materia y la noción de gravedad semántica-. El análisis muestra que, en el episodio estudiado, los intercambios discursivos transitan entre diferentes categorías correspondientes a la gravedad semántica. Así, la transición de una conceptualización en el nivel macroscópico a una centrada en el nivel submicroscópico, se relaciona con una disminución en la gravedad semántica. Finalmente se discuten algunas implicaciones para la enseñanza.
Diseño de actividades para una didáctica de la Astronomía vivencialmente significativa
Authors: Camino Néstor Eduardo
Published: March 2021

La Didáctica de la Astronomía es una especialidad aún joven, a pesar de unos cuarenta años de desarrollo en el mundo y poco menos en Latinoamérica. Aunque consolidada, tiene todavía mucha potencialidad por desarrollar para profundizar y mejorar las acciones que hemos ido concretado hasta el presente. Podríamos indicar dos grandes inconvenientes para que tal potencialidad se manifieste en las aulas con experiencias creativas y de calidad. El primero, quizás el más importante y urgente a resolver, es la falta de jóvenes educadores e investigadores formados en esta especialidad, aquello de la “masa crítica” necesaria para que una comunidad científica funcione adecuadamente. El segundo inconveniente, vinculado sin dudas al primero, es la falta de una “memoria didáctica”: un corpus de experiencias, materiales, recursos, reales y probados, disponibles libremente para quienes quieran acceder a ellos, para replicarlos y transformarlos. Presentamos algunas reflexiones y propuestas concretas sobre el segundo de los inconvenientes antes citados, en especial con el fin de mostrar una manera posible, valiosa según nuestra experiencia, para el desarrollo de acciones didácticas novedosas. Para el diseño de las mismas se han tomado en cuenta los conceptos de espacio y tiempo y su vinculación con los aspectos observacionales de la Didáctica de la Astronomía, los fundamentos epistemológicos como el mecanismo lógico hipotético-deductivo en la actividad experimental, la capacidad de tomar decisiones creativas en el proceso de contrastación entre el modelo y la realidad bajo estudio, y la dimensión vivencial de las acciones didácticas vinculadas al cielo. Las propuestas concretas son dos: deducir la posición del Sol en el cielo a partir de una fotografía de la sombra de nubes tomada desde un avión, y deducir la fase de la Luna a partir de una fotografía de una luminaria esférica blanca. Las propuestas presentadas han sido probadas en aulas reales durante años.
El tomate que no flota en agua: una posible secuencia para el aprendizaje activo de ingravidez
Authors: Slisko Josip
Published: March 2021

Es conocido que los tomates flotan en el agua. Usando un tornillo o clavo y un imán de neodimio es posible cambiar tal comportamiento, manteniendo un tomate en el fondo de una botella llena de agua. Se solicita que los estudiantes, quienes no conocen tal procedimiento, propongan sus propios procedimientos para lograr la situación descrita. Al llegar a conocer el procedimiento mencionado, por propio pensamiento creativo o, más probable, por la revelación del docente, se solicita que los estudiantes predigan el comportamiento del tomate al remover el imán de neodimio. Finalmente, los estudiantes deben predecir el comportamiento del tomate si simultáneamente se remueve el imán de neodimio y se deja caer la botella. Como en la caída libre, dentro de la botella no hay campo gravitacional y el agua deja de ejercer la fuerza de empuje, el tomate se queda en el fondo de la botella sin la presencia del imán. Tal acontecimiento es una nueva demonstración de ingravidez para las aulas de física. Puede servir como el punto de partida para construir un conocimiento transferible sobre la ausencia del campo gravitacional interno en los sistemas en caída libre.
PKB i TFP w powiatach województwa wielkopolskiego. Oszacowanie i ocena zróżnicowania
Authors: Dańska-Borsiak Barbara
Published: March 2021

W prezentowanych badaniach oszacowano poziom PKB i łączną produktywność czynników produkcji (TFP) dla powiatów województwa wielkopolskiego w latach 2008–2018 oraz dokonano analizy ich zróżnicowania pod tym względem. W szczególności zbadano występowanie zależności przestrzennych w rozkładach obu zmiennych. Na podstawie wartości globalnych i lokalnych statystyk Morana wskazano powiat miasto Poznań jako tzw. hot-spot, a więc region o wysokich wartościach PKB oraz TFP, pozytywnie oddziałujący na region sąsiedni. Zależności przestrzenne w skali globalnej (całego województwa) praktycznie nie występują, natomiast zauważalne są różnice w zależności od dominującego profilu gospodarczego powiatu.
Partnerstwo publiczno-prywatne jako forma wsparcia inwestycji lokalnych w województwie wielkopolskim
Authors: Walenia Alina
Published: March 2021

Celem artykułu jest analiza uwarunkowań prawnych, organizacyjnych i finansowych współpracy sektora publicznego, głównie samorządowego, z sektorem prywatnym dotyczącej realizacji przedsięwzięć inwestycyjnych mających na celu wspieranie rozwoju lokalnego. Współpraca ta określana jest jako partnerstwo publiczno-prywatne (PPP) i stanowi formę pozyskiwania kapitału przez samorząd terytorialny, z przeznaczeniem na realizację zadań ustawowych, szczególnie świadczenia usług publicznych. Oceny i uwagi sformułowane zostały z wykorzystaniem materiałów empirycznych, wyników badań ankietowych przeprowadzonych w 50 jednostkach samorządu terytorialnego oraz w 60 podmiotach gospodarczych prowadzących działalność na terenie ankietowanych gmin województwa wielkopolskiego. Podjęta problematyka badawcza pozostaje ciągle aktualna, ponieważ zakres planowanych zadań publicznych bardzo często przewyższa możliwości finansowe samorządu lokalnego. Władze samorządowe poszukują zatem finansowego wsparcia wśród partnerów z sektora prywatnego. Z wykorzystaniem wyników badań ankietowych wyszczególnione zostały czynniki ograniczające współpracę w ramach PPP, tj. sektora samorządowego z prywatnym, w zakresie finansowania inwestycji komunalnych. Do oceny zjawiska PPP w województwie wielkopolskim użyte zostały dane publikowane na stronie platformy PPP, zawierającej bazy zamierzeń inwestycyjnych, bazy projektów PPP z zawartymi umowami, bazy umów rozwiązanych, nierealizowanych (bazy te są aktualizowane w okresach miesięcznych lub kwartalnych).
The relationship between expression of VIMENTIN and CD146 genes in breast cancer
Authors: Kocemba-Pilarczyk Kinga A. , Dudzik Paulina , Leśkiewicz Katarzyna
Published: March 2021

Objectives

CD146 is an adhesive molecule that was originally reported on malignant melanoma cells as a protein crucial for cell adhesion. It is now known that high expression of the CD146 protein is not only characteristic of melanoma, but it occurs on a number of cancers, contributing to worse prognosis and increased aggressiveness. Independent in vitro studies in breast cancer have shown that CD146 protein alone can induce a change in epithelial to mesenchymal transcriptional profile, which is the basis of the tumor aggressiveness and metastasis.

Methods

In the following work, the correlation coefficients were analyzed between the genes of the mesenchymal profile and the CD146 gene in 10 independent transcriptomic data of breast cancer patients.

Results

The analysis confirmed the relationship between CD146 expression and mesenchymal profile genes, pointing VIMENTIN as the gene which expression is most strongly correlated with the CD146, suggesting that both genes, CD146 and VIM may be directly controlled by the same mechanism or regulate one another.

Conclusions

The analysis points a potential route for research on the CD146 gene expression, which may lead to understanding of its regulation in breast cancer, contributing to the development of new therapeutic strategies targeting highly metastatic breast cancer cells.

Published: March 2021

“Bryndza” cheese is an important Slovak traditional regional product. New knowledge on the role of microorganisms involved the “Bryndza” ripening process may provide valuable data on its quality and safety. In our study, the “Bryndza” made from pasteurized ewes milk was studied towards total count of bacteria, coliforms bacteria, enterococci, lactic acid bacteria, and microscopic filamentous fungi. All those groups of microbiota were detected using classical microbiological methods and identified using mass spectrometry. A total of 3,758 isolates were identified with score higher than 2.00. Altogether, 13 families, 24 genus, and 44 species of microbiota were identified in Slovak cheese “Bryndza.” The most often isolated species were yeasts Yarrowia lipolitica and Dipodascus geotrichum and the lactic acid bacteria Lactobacillus paracasei subsp. paracasei.
Rare norisodinosterol derivatives from Xenia umbellata: Isolation and anti-proliferative activity
Authors: Bawakid Nahed Obaid , Alarif Walied Mohamed , Abdel-Lateff Ahmed
Published: March 2021

Two new rare 30-norisodinosterol derivatives, 23,24-dimethylcholest-16-ene-3β,5α,6β,11α,20(R)-pentol 3-monoacetate (1) and 23,24-dimethylcholest-16-ene-3β,5α,6β,20(R)-tertrol 3-monoacetate (2), along with a known steroid, 3β,5α,6β,11α,20β-pentahydroxygorgosterol (3), were identified from Xenia umbellata. The structures of the isolated compounds were determined by analyses of the measured spectra (1D and 2D nuclear magnetic resonance, mass spectrometry, and infrared). The biosynthetic pathway of the new norisodinosterols was proposed. Compound 1 exhibited potent cytotoxicity against HepG2, PC-3, and HT-29 with IC50 values of 4.70 ± 0.2, 5.60 ± 0.6, and 4.00 ± 0.4 μg/mL, respectively. On the contrary, compound 3 showed less potent cytotoxicity against HepG2 with IC50 value of 22.20 ± 1.0 μg/mL. Two DNA-binding dyes have been used for the morphological detection of viable, apoptotic, and necrotic cells. The early apoptotic cell death was observed in all types of treated tumour cells. The late apoptotic cells are highly present in HepG2 cells with compound 3 compared with other cancer cells except for compound 1. The anti-proliferative activity of compounds 1 and 3 warranted further investigation.

Causes ofsedimentation were searched in watersheds changes overtime. These were identified by comparison of historicalaerial imagery (1949) with existing aerial photographs.
Stability of an abandoned siderite mine: A case study in northern Spain
Authors: Trigueros Emilio , Cánovas Manuel , Arzúa Javier , Alcaraz Manuel
Published: March 2021

Bodovalle is an iron carbonate mine located in Gallarta (near Bilbao, northern Spain), which is currently in the closure stage. The deposit was first exploited as an open-pit mine and later as an underground mine. The underground mine currently has 40 large rooms with rib pillars, occupying an area of 2,000 m long by 600 m wide. Room depth is around 200 m. The main geotechnical incident occurred in the NW1N zone, where an over-exploited rib pillar in poor condition was partially removed, leaving a 70-m roof span that eventually collapsed in 1999, resulting in a surface crater measuring 60 m in diameter. The collapse was preceded by noises and movements detected outside the mine. The subsidence was improved by means of infilling and monitoring. In 2014, residents living in homes built over the abandoned mine rooms detected very loud noises similar to those of 1999. The article describes a stability review carried out using advanced numerical methods (finite element method and boundary element method) and the geomechanical parameters obtained from a back analysis of the 1999 collapse.

Published: March 2021

The study investigated the effects of the addition of 0% (control group, CG), 0.25, 0.35, and 0.45% superfine smashed okra powder (SSOP) or carrageenan (CAR), and 0.25% SSOP – 0.35% CAR complex (OC) on the quality of chicken meatballs. Chicken meatballs fabricated with the SSOP-CAR complex showed better quality as compared to the other treatments. The lowest cooking loss was observed in the OC group, which corresponded to significantly decreased relaxation times of low-field nuclear magnetic resonance (LF-NMR) (T
21 and T
22) (P < 0.05). Compared to CG, The L* and a* values of chicken meatballs were significantly decreased due to the addition of SSOP (P < 0.05), and the additions of SSOP and CAR significantly increased the storage modulus (G′) and loss modulus of chicken meat batter upon heating (P < 0.05). Besides, the OC and 0.45% CAR groups showed the highest texture profile values for hardness and chewiness (P < 0.05). The sensory evaluation revealed that the chicken meatballs emulsified with the OC had the best overall acceptability. The results indicated that OC could be a great feasible and potential application in the meat industry, especially in the development of functional emulsified meat products.
Recurrence relations for a family of iterations assuming Hölder continuous second order Fréchet derivative
Authors: Gupta Dharmendra Kumar , Martínez Eulalia , Singh Sukhjit , Hueso Jose Luis , Srivastava Shwetabh , Kumar Abhimanyu
Published: March 2021

The semilocal convergence using recurrence relations of a family of iterations for solving nonlinear equations in Banach spaces is established. It is done under the assumption that the second order Fréchet derivative satisfies the Hölder continuity condition. This condition is more general than the usual Lipschitz continuity condition used for this purpose. Examples can be given for which the Lipschitz continuity condition fails but the Hölder continuity condition works on the second order Fréchet derivative. Recurrence relations based on three parameters are derived. A theorem for existence and uniqueness along with the error bounds for the solution is provided. The R-order of convergence is shown to be equal to 3 + q when θ = ±1; otherwise it is 2 + q, where q ∈ (0, 1]. Numerical examples involving nonlinear integral equations and boundary value problems are solved and improved convergence balls are found for them. Finally, the dynamical study of the family of iterations is also carried out.
Inverse problem of Mueller polarimetry for metrological applications
Authors: Novikova Tatiana , Bulkin Pavel
Published: March 2021

Inverse problem of Mueller polarimetry is defined as a determination of geometrical features of the metrological structures (i.e. 1D diffraction gratings) from its experimental Mueller polarimetric signature.
This nonlinear problem was considered as an optimization problem in a multi-parametric space using the least square criterion and the Levenberg–Marquardt algorithm.
We demonstrated that solving optimization problem with the experimental Mueller matrix spectra taken in conical diffraction configuration helps finding a global minimum and results in smaller variance values of reconstructed dimensions of the grating profile.
Should Bitcoin Be Classified as Money?
Authors: Passinsky Asya
Published: March 2021

The advent of virtual currencies such as bitcoin raises a pressing question for lawmakers, regulators, and judges: should bitcoin and other virtual currencies be classified as money or currency for legal and regulatory purposes? I examine two different approaches to answering this question—a descriptive approach and a normative approach. The descriptive approach says that bitcoin and other virtual currencies should be classified as money or currency just in case they really are money or currency, whereas the normative approach says that this question of classification should be answered on the basis of substantive normative considerations. I argue against the descriptive approach and in favor of the normative approach.
Visual metaphtonymy in automobile femvertising
Authors: Chatti Sami
Published: March 2021

In a 2017 landmark reform, Saudi authorities decided to lift the ban on women driving in this conservative society. In tribute to women’s newly-gained freedom to drive, major automakers turned to Twitter to launch creative femvertising campaigns that vividly articulate the female empowering motto ‘driving is feminine’. Building on the eloquence of visual rhetoric, which combines the communicative force of figurative language with the expressive potential of visual imagery, automobile advertisers resorted to visual metaphtonymy to efficiently target prospective female consumers. The selection of this visual compound, which emerges from the intricate interplay between metaphor and metonymy, allows for a dynamic interaction between the highlighting function of metonymy and the mapping role of metaphoric thought to establish informed parallels between femininity and automobility. Analysis of survey data on the likeability, complexity and effectiveness of a representative sample of four digital automobile advertisements asserts the role and value of visual metaphtontonymy in automobile femvertising.
Culturally responsive teaching knowledge and practices of online faculty in educational administration: a pilot study
Authors: Ballenger Julia , Jiang Mei
Published: March 2021

The new statistics project that the nation will become “Minority White” in 2045 where Whites will comprise 49.7% of the population. In contrast, Hispanics will comprise 24.6%, Blacks 13.1%, Asians 7.9%, and 3.8% for multiracial populations. Given such shifts in the demographic trends, a culturally inclusive curriculum design and delivery is critical for all students’ success. The purpose of this pilot quantitative comparative research study was to assess Culturally Responsive Teaching Knowledge (CRT) and Culturally Responsive Educational Practices (CREP) in Texas public university faculty who teach and/or advise online Master’s and/or Doctoral students of color, military students, LGBTQ students, religious minority students, and international students in Educational Administration. All respondents in this pilot research study believed Culturally Responsive Teaching was “very important”. However, their self-reported ratings on knowledge of CRT were significantly lower than their value of CRT. These findings revealed the respondents recognized the importance and necessity of cultural diversity in online learning. They viewed cultural differences as assets in online courses. However, they self-perceived their own knowledge of cultural diversity in online teaching was insufficient. With the changing student demographics and increase in international students, faculty members should incorporate diverse learning activities into the online course design to promote equitable learning outcomes. These instructional methods are particularly important to the online graduate programs in the fields of Educational Administration, Instructional Administration, and Educational Leadership.
Comparison of Two Ecological Momentary Intervention Modules for Treatment of Depression on Momentary Positive and Negative Affect
Authors: Ornée Daan A. , Oldehinkel Albertine J. , Bastiaansen Jojanneke A.
Published: March 2021

Background: Ecological Momentary Assessment (EMA), comprising repeated self-assessments in daily life, have shown promise as an intervention strategy for depression. Whether the content of such assessments influences affect has hardly received attention. The current study consists of two EMA intervention (EMI) modules, enabling us to compare the impact of EMI content on the course of momentary affect during the intervention. Methods: The intervention, implemented as add-on to regular depression treatment, consists of intensive self-monitoring (5x/day, 28 days) and weekly personalized feedback. Patients with depressive complaints (N = 110; Mage = 32.9, SD = 12.2; 44.5% male) were randomly assigned to one of two treatment modules focusing on activities and positive affect (“Do”) or on thoughts and negative affect (“Think”). Results: Linear mixed models showed no significant (p > .18) differences between the two modules on both positive and negative affect over time. Across modules positive affect showed an initial decreasing trend, leveling off towards the end of the intervention period. Negative affect did not change significantly over time (p > .06). Limitations: Both modules assessed positive and negative affect, enabling a direct comparison but potentially decreasing the impact of their differential focus. Conclusions: In our sample, the focus of the EMI was not associated with differential effects on momentary affect. This implies that a focus on thoughts and negative affect compared to positive affect and activities may not lead to added adverse effects on mood, which is an often-voiced concern when using EMA in both research and clinical practice.
Assessing and Implementing a Sustainable Holistic Planning System
Authors: Backus Erik C. , Bird Stephen
Published: March 2021

In 2019, the New York Olympic Region received the first Leadership in Energy and Environmental Design (LEED) for Communities Certification (gold) for a rural multi-jurisdictional region comprised of Lake Placid Village, North Elba Town, the Olympic Regional Development Authority, and the Lake Placid School System. Much of the work involved in this initiative was executed by 14 undergraduate students and two faculty members from Clarkson University working in partnership with the U.S. Green Building Council, and four local jurisdictions. The endeavor was successful and unique in several facets. First, it provided an experiential project-based education in the application of a sustainable holistic planning system, LEED for Communities/Cities. Second, it demonstrates the value of a university collaboration with a rural region and its communities. Third, it developed the first rural regional model for smart community planning that integrated multiple jurisdictions and stakeholders. Finally, it provides a replicable template for implementation and operation by other communities with institutions of higher learning. A variety of challenges remain, however, for emerging sustainable holistic planning systems in metrics development, civic and stakeholder engagement, determination of efficacy, and implementation optimization. Readers will emerge with an improved understanding of sustainable holistic planning systems, knowledge of multi-jurisdictional planning concerns in sustainability metrics, and insight into implementation of these systems as a pedagogical tool and partnership mechanism.

The estimation of important carbon fluxes in a changing Arctic environment remains a challenge, one that could benefit from the development of biomarkers that distinguish between sympagic (ice-associated) and pelagic organic material. Products of 10S-DOX-like lipoxygenase and fatty acid cis-trans isomerase (CTI) activity of bacteria attached to sympagic particulate organic matter (POM) were proposed previously as potential biomarkers of the contribution of sympagic biota to carbon fluxes to the seafloor. To date, neither the bacteria involved in such enzymatic activities nor the detection of these potential biomarkers at their presumed source (i.e., sea ice) has been investigated. Here, we determined and compared the diversity of prokaryotic communities (based on operational taxonomic units) attached to sea ice POM and under-ice sinking particles during an early stage of ice melt (brine drainage) in Baffin Bay (Canadian Arctic). Based on a time series of biodiversity analyses and the quantification of lipid tracers of these two bacterial enzymatic activities, we suggest that CTI-active bacteria, exposed to hypersaline stress, are attached to algal POM just above bottom sea ice and released into the water column following brine drainage. In contrast, bacteria attached to sinking particles and exhibiting 10S-DOX-like lipoxygenase activity are suggested to come from the bottommost layer of sea ice, where they may play a role in the detoxification of algae-produce free fatty acids. These results provide a refined view of the potential use of products of CTI activity as specific biomarkers of sympagic organic matter.
INVESTIGATING THE IMPACT OF FOREIGN DIRECT INVESTMENT ON POVERTY REDUCTION EFFORTS IN AFRICA
Authors: TSAURAI Kunofiwa
Published: March 2021

The study explored whether the complementarity between foreign direct investment(FDI) and natural resources availability led to poverty reduction in Southern and WesternAfrican nations using panel data analysis (fixed effects, random effects, pooled ordinaryleast squares (OLS) and dynamic generalised methods of moments (GMM) with dataspanning from 2002 to 2012. The objective emanates from the theoretical view that if thecountries that are receiving FDI have abundance of natural resources, a large number ofthe unemployed people are likely to get jobs, earn income and get out of poverty zone.Three measures of poverty were used in the current study, namely life expectancy atbirth, total (years), household consumption expenditure as a ratio of gross nationalproduct and mortality rate and infant (per 1 000 live births). Generally, all the four paneldata analysis methods produced similar finding: the interaction between FDI and naturalresources reduced poverty levels in African countries studied. Southern and WesternAfrican nations are therefore urged to implement FDI enhancement policies which attractforeign investors into the natural resources extraction sector if they want to sustainablyreduce poverty. Future studies should investigate other macroeconomic factors that mustbe available in the host country before FDI reduce poverty in all its forms.

Analizar a importancia económica da pesca require de información económica detalladarespecto dos inputs, os empregos dos produtos ou a demanda, sendo as táboas input-outputa ferramenta que mellor capacidade ten para amosar a rede de interrelacións e dependenciasentre os distintos sectores da economía.A partir da Táboas input-output da Pesca-Conserva Galega 2011 podemos soster que ocomplexo mar-pesca galega, acadou en 2011 unha cifra de produción de 3.705,4 millóns deeuros, dos que 2.434,7 lle corresponderon a industria conserveira e de alimentos do mar e1.270,7 ao conxunto dos sectores marisqueiro, pesqueiro, mitícola e piscícola mariño,derivándose deles os impactos directos e indirectos, fundamentalmente sobre a economíagalega, pero tamén sobre a economía española e mundial.Da análise da función de producción da pesca galega despréndese que constitúe unhaactividade económica cun elevado poder de arrastre, que produce tiróns en forma de redee/ou de constelación industrial e de servizos nun moi elevado número de sectores. A relacióneconómica directa ven expresada pola dependencia cos 74 sectores que aparecen nas táboas,pero indirectamente relacióna-se á súa vez con todos e cada uns dos que destes dependen.Así mesmo, constátase que se trata dunha actividade económica claramente industrial.

A feature of the agro-industrial sphere is the high probability of distribution (remoteness) of production or research sites in areas far from each other for a considerable distance. Moreover, the center for collecting information and processing it, as a rule, is concentrated in one compact place. For research institutions, this feature often acquires a state of rather urgent problem, which requires the search for new innovative approaches. The paper proposes elements of the concept of construction and technological solutions for methods of operational data transfer of field research from agricultural areas to a remote database for data storage with the possibility of feedback. As an example, the procedure of qualification examination of plant varieties with the definition of the criteria of "difference, homogeneity and stability" and "suitability for propagation of the variety in Ukraine" was chosen.
On a method for approximate solution of a mixed boundary value problem for an elliptic equation
Authors: Fairuzov Mahmut E. , Lubyshev Fedor V.
Published: March 2021

A mixed boundary value problem for an elliptic equation of divergent type with variable coefficients is considered. It is assumed that the integration region is a rectangle, and the boundary of the integration region is the union of two disjoint pieces. The Dirichlet boundary condition is set on the first piece, and the Neumann boundary condition is set on the other one. The given problem is a problem with a discontinuous boundary condition. Such problems with mixed conditions at the boundary are most often encountered in practice in process modeling, and the methods for solving them are of considerable interest. This work is related to the paper [1] and complements it. It is focused on the approbation of the results established in [1] on the convergence of approximations of the original mixed boundary value problem with the main boundary condition of the third boundary value problem already with the natural boundary condition. On the basis of the results obtained in this paper and in [1], computational experiments on the approximate solution of model mixed boundary value problems are carried out.

Published: March 2021

Introduction. The article deals with the conditions for growing greenhouse plants. Supplementary lighting supports the process of plant photosynthesis and the microclimate in the greenhouse. The authors suggest the ways to reduce energy consumption in greenhouses by controlling the microclimate and process of supplementary lighting in greenhouses.
Materials and Methods. Special lighting and temperature are required for growing greenhouse plants. A method of efficient plant growing is light and temperature control. The development of a control algorithm requires the mathematical models that relate the process of photosynthesis to the microclimate parameters. There are given the mathematical models based on the experimental data.
Results. The control system and algorithm to control plant-growing conditions have been developed to maintain the greenhouse microclimate. LED lamps are used to control the lighting process. The authors present the developed block diagram of the control system, which contains four channels responsible for the main energy-intensive microclimate factors. The description of the algorithm of the greenhouse light-temperature control is given.
Discussion and Conclusion. In conclusion, the need to maintain the greenhouse microclimate and supplementary lighting with the different radiation spectrum for the efficient cultivation of greenhouse plants is shown. The developed structure and control algorithm for the supplementary plant lighting process and greenhouse illumination through using LED lamps help reduce energy consumption.

Published: March 2021

The objective of this study was to relate the degree of satisfaction that graduates had with the supervisory approach during the development of the undergraduate thesis. A cross-sectional study, including 102 graduate students from the Faculty of Dentistry of the Universidad Nacional Mayor de San Marcos. Lima. Peru. The survey technique was used to collect information on the satisfaction of the thesis supervision (valued on a score from 1 to 6, where higher scores showed greater satisfaction) and the supervisor's approach. Results showed that 59% of supervisors had a collaborative approach, 29.6% a non-directive approach. Collaborative supervisors obtained a higher satisfaction score (5.2±0.7) while the directive approach obtained the lowest score (3.3±0.5) (p<0.05). Women presented a higher satisfaction score (5.4±0.2 vs 4.8±0.4) (p<0.05). There is a relationship between the collaborative supervision style and greater student satisfaction during the thesis process. Students indicated being less satisfied with the managerial supervision style of the thesis.

In recent years, machine learning techniques have been developed and used to build intelligent information systems for solving problems in various fields. In this study, we have used Optimized Inference Intelligence System namely ANFIS-PSO which is a combination of Adaptive Neural-Fuzzy Inference System (ANFIS) and Particle Swarm Optimization (PSO) for the estimation of shear strength parameters of the soils (Cohesion “C” and angle of internal friction “φ”). These parameters are required for designing the foundation of civil engineering structures. Normally, shear parameters of soil are determined either in the field or in the laboratory which require time, expertise and equipments. Therefore, in this study, we have applied a hybrid model ANFIS-PSO for quick and cost-effective estimation of shear parameters of soil based on the other six physical parameters namely clay content, natural water content, specific gravity, void ratio, liquid limit and plastic limit. In the model study, we have used data of 1252 soft soil samples collected from the different highway project sites of Vietnam. The data was randomly divided into 70:30 ratios for the model training and testing, respectively. Standard statistical measures: Root Mean Square Error (RMSE), Mean Absolute Error (MAE) and Correlation Coefficient (R) were used for the performance evaluation of the model. Results of the model study indicated that performance of the ANFIS-PSO model is very good in predicting shear parameters of the soil: cohesion (RMSE = 0.075, MAE = 0.041, and R = 0.831) and angle of internal friction (RMSE = 0.08, MAE = 0.058, and R = 0.952).
