Decolonized Trauma: Narrative, Memory and Identity in Chimamanda Ngozi Adichie’s Americanah
Authors: Pourgharib Behzad , Asl Moussa Pourya , Esmaili Somayeh
Published: June 2023

Even though literary works serve as excellent media for bearing witness to trauma, postcolonial and diasporic literary texts are often dismissed for their falsified accounts of traumatic life experiences. Recent studies on African American literature have stressed the need for a decolonized conceptualization of trauma that would not only disrupt the long-existing white Global Northern perspectives but also recognize feelings of empathy and solidarity among members of the community in these literary corpora. The present study adopts a hybrid analytical framework to examine the representations of trauma in the Nigerian American writer Chimamanda Ngozi Adichie’s Americanah (2013). Specifically, we draw upon Gérard Genette’s narrative levels, Ron Eyerman’s collective memory, and Jeffrey Charles Alexander’s collective identity to argue that the novel defies conventional forms of narrative by depicting postcolonial and diasporic identities as volatile and dynamic constructs. The findings indicate the multiple ways in which the story presents diasporic Africans – that is, the female protagonist Ifemelu and her male lover Obinze – as capable of overcoming the adverse effects of traumatic memories by chronicling an authentic record of their experiences. The study also reveals that the leading female character, like the novelist Adichie, creates an empowering platform for migrants of various ethnicities to speak up about their traumatic experiences, and thereby establish what is called ‘cross-cultural solidarity’ in reconstructing a new community.

In this paper, we represent that the following three-dimensional system of difference equationsxn+1=αyn+aynyn−βzn−1, yn+1=βzn+bznzn−γxn−1, zn+1=γxn+cxnxn−αyn−1,  n∈ℕ0,$$\matrix{{{x_{n + 1}} = \alpha {y_n} + {{a{y_n}} \over {{y_n} - \beta {z_{n - 1}}}},\quad {y_{n + 1}} = \beta {z_n} + {{b{z_n}} \over {{z_n} - \gamma {x_{n - 1}}}},\quad {z_{n + 1}} = \gamma {x_n} + {{c{x_n}} \over {{x_n} - \alpha {y_{n - 1}}}},\qquad n \in {{\mathbb N}_0},} \cr} $$where the parametersa, b, c, α, β, γand the initial valuesx−i,y−i,z−i,i∈ {0, 1}, are real numbers, can be solved in closed form by using transformation. We analyzed the solutions in 10 different cases depending on whether the parameters are zero or nonzero. It is noteworthy to depict that the solutions of some particular cases of this system are presented in terms of generalized Fibonacci numbers. Note that our results considerably extend and improve some recent results in the literature.

It is challenging to effectively purge wastewater containing heavy metal ions at low concentration. In order to remove trace Cr (VI) from wastewater efficiently, a positively charged microporous membrane was prepared by firstly non-solvent induced phase separation (NIPS) of amphiphilic polymer and secondly surface quaternization modification. The morphologies, surface roughness, surface charge, hydrophilicity, and pore size of membranes were characterized. Based on the dual action of micellar adsorption and charge repulsion, when surfactant is 4 mM and Cr (VI) is 60 ppm, the surface quaternization membrane (Q-MPVD) achieves 99.8 % Cr (VI) rejection simultaneously accompanied by a permeability of 100 LMH/bar. Meanwhile, the effects of STAC concentration, Cr (VI) concentration, pH as well as inorganic salt concentration on the composite micellar size, and Cr (VI) rejection performance were investigated, respectively. Moreover, the Q-MPVD membrane shows an excellent separation stability over a wide pH range, indicating its application perspective in engineering process. In summary, this work provided a positively charged membrane with high-efficiency performance for treating practical trace Cr (VI)-containing industrial wastewater.
A closer inspection of the structural, mechanical, optical and radiation shielding properties of GeO2-doped magnesium-telluroborate glasses

Published: June 2023

GeO2-doped magnesium-telluroborate transparent glasses were synthesized in the current investigation using the traditional melt-quench procedure. XRD and FT-IR were used to examine the glasses’ structural properties. Following the measurement of the density, various physical parameters (including oxygen molar volume, oxygen packing density, etc.) were estimated and examined. From the FTIR results, one can deduce that clear structural alterations are seen which support the presence and conversion of BO3 and BO4 units. This is a result of the glass network forming more GeO4, TeO4, and BO4 units, which means that decreased NBO is forming, and more stiff networks are forming as a result. The increase in the overall stretching force constant of the glasses may also have an impact on the elastic moduli. The optical parameters were studied as optical energy band gap, Urbach energy and refractive index of the fabricated glass. According to the HVL data, the current glasses have a significant ability to lessen the intensity of gamma rays with lower energy. The glass with a small amount of GeO2 has a high HVL, whereas the glass with a higher amount of GeO2 has a lower HVL, as shown by the HVL data. The G5 glass demonstrated its superiority as a shielding glass over the other glass samples (G1–G4).

The flow velocity field reconstruction on grid cells using a mixed finite element method is proposed. Cases of sinks and sources in cells as well as different cell partitionings are considered. Algorithms for streamlines and time of flight calculation are provided. Performance and convergence of the method are demonstrated on a set of reference problems.
SIMUG – finite element model of sea ice dynamics on triangular grid in local Cartesian basis
Authors: Petrov Sergey S. , Iakovlev Nikolay G.
Published: June 2023

The paper presents the dynamical core of the new sea ice model SIMUG (Sea Ice Model on Unstructured Grid) on the A- and CD-types of unstructured triangular grids in the local-element basis on sphere. Three standardized box tests to reproduce the Linear Kinematic Features (LKFs), and the short-term forecast in the real Arctic Ocean geometry with the realistic atmosphere and ocean forcing demonstrate the model quality compared to other sea ice models like CICE, FESOM, MITgcm, and ICON-O. The distinctive features of the model presented are a wide choice of transport schemes, and the new numerical implementation with the serial and parallel C++ coding and INMOST, Ani2D, and Ani3D packages to deal with unstructured grids. Code profiling and scalability assessment are carried out. In general, the A-version of the ice drift model works faster, but has fewer degrees of freedom on the same grid. Due to the increase in the degrees of freedom, the model on the CD grid gives ultra-resolution of LKFs, but requires more strict conditions for stability.
DOT1L bridges transcription and heterochromatin formation at mammalian pericentromeres

Published: June 2023

Repetitive DNA elements are packaged in heterochromatin, but many require bursts of transcription to initiate and maintain long‐term silencing. The mechanisms by which these heterochromatic genome features are transcribed remain largely unknown. Here, we show that DOT1L, a conserved histone methyltransferase that modifies lysine 79 of histone H3 (H3K79), has a specialized role in transcription of major satellite repeats to maintain pericentromeric heterochromatin and genome stability. We find that H3K79me3 is selectively enriched relative to H3K79me2 at repetitive elements in mouse embryonic stem cells (mESCs), that DOT1L loss compromises pericentromeric satellite transcription, and that this activity involves possible coordination between DOT1L and the chromatin remodeler SMARCA5. Stimulation of transcript production from pericentromeric repeats by DOT1L participates in stabilization of heterochromatin structures in mESCs and cleavage‐stage embryos and is required for preimplantation viability. Our findings uncover an important role for DOT1L as a bridge between transcriptional activation of repeat elements and heterochromatin stability, advancing our understanding of how genome integrity is maintained and how chromatin state is set up during early development.
PATJ and MPDZ are required for trophectoderm lineage specification in early mouse embryos

Published: June 2023

In brief

During the morula to blastocyst transformation, polarity establishment in outer cells is a prerequisite for trophectoderm lineage specification. This study reveals the roles of polarity proteins PATJ and MPDZ in trophectoderm lineage fate decision.

In mouse preimplantation embryos, cell polarity plays a crucial role in the first lineage specification. PATJ and its homolog MPDZ are the main members of CRB–PALS1–PATJ (CRUMBS–Protein associated with Lin7 1–Pals-associated tight junction protein) apical polarity complex. They act as adaptor proteins connecting CRB–PALS1 and tight junction proteins, making them essential for cell polarization and stabilization of apical junctions. However, their roles in regulating trophectoderm differentiation and blastocyst development remain unclear. In this study, PATJ and/or MPDZ were downregulated by the microinjection of specific RNA interference constructs into zygotes. Downregulation of PATJ alone did not severely affect early embryonic development and trophectoderm lineage differentiation although it slowed down the blastocyst formation. Depletion of PATJ and MPDZ did not affect compaction and morula development but impaired blastocyst formation. Furthermore, the expression of trophectoderm-specific transcription factors and trophoblast differentiation was compromised in the absence of PATJ/MPDZ. These abnormalities might result from the breakdown of apical domain in the outer cells of the embryo. The loss of PATJ/MPDZ caused the breakdown of CRB and PAR polarity complexes as well as deficiencies in tight junctions and actin filaments. These defects led to ectopic activation of Hippo signaling in the outer cells of developing embryos, ultimately suppressing Cdx2 expression and trophectoderm differentiation. Altogether, PATJ and MPDZ are essential for trophectoderm lineage differentiation and normal blastocyst morphogenesis via the regulation of the establishment of apical domain, formation of tight junctions, phosphorylation and localization of YAP, and expression of trophectoderm-specific transcription factors.

İntraoral Lipom: Bir Olgu Sunumu

Amaç

Lipomlar, fibröz doku tarafından lobüllere ayrılan, adipoz doku orijinli, çoğunlukla normal mukoza ile örtülü, asemptomatik, benign mezenşimal neoplazmlardır. Genellikle sebebi bilinmese de etyolojide ailesel yatkınlık, travma, alkol, radyasyon ve bazı kronik hastalıklar suçlanmaktadır. Erkeklerde kadınlara göre daha fazla saptanmıştır. Bu olgu sunumunda yanakta az rastlanan ve oldukça büyük boyutlara ulaşmış lipomun tedavisi sunulacaktır.

Olgu

Yirmi yedi yaşında kadın hasta, uzun süredir mevcut olan ve boyutları giderek artan sağ yanakta şişlik şikâyetiyle kliniğimize başvurdu. Yapılan muayenede sağ bukkal mukoza bölgesinde yaklaşık 2x2 cm boyutunda, yumuşak kıvamlı, hareketli ve düzgün sınırlı kitle tespit edildi. Lokal anestezi altında intraoral yaklaşımla kitle total olarak eksize edildi. Histopatolojik inceleme sonucu, lipom olarak gelen hastanın, 2 yıllık takibinde nüks görülmedi.

Bulgular

Lipomlar, kapsüler adipoz dokunun benign neoplazmları olup, genellikle subkutanöz dokularda görülseler de derin dokularda da görülebilirler. Maksillofasiyal bölgede nisbeten az rastlanırlar. En sık parotis bölgesinde görülürler, bunu yanak izler. Tanı amacıyla ince iğne aspirasyon biyopsisi, ultrason, BT ve manyetik rezonans görüntüleme yöntemleri kullanılmaktadır. Ayrıcı tanıda, fibroepitelyal polip, anjioma, dermoid kist, fibroma ve liposarkom düşünülmelidir. Temel tedavi şekli cerrahi eksizyon olan lipomlar, fonksiyonel veya kozmetik nedenlerle eksize edilebilirler ve total rezeksiyonu takiben genellikle rekürrens göstermezler.

Sonuç

Lipom benign bir tümör olup tüm vücutta yaygın görülmekle beraber ağız içi lipomlar, rutin diş muayeneleri sırasında fark edilebilen nadir bir antitedir. Etyolojisi net olarak bilinmemektedir. Kesin tanı ve tedavisi için cerrahi eksizyon uygundur. Bukkal bölgedeki lipomlar intraoral yolla güvenli bir şekilde total olarak eksize edilebilir. Bu olguda total olarak eksize edilen lipomun 2 yıllık takibinde herhangi bir şikâyet ve nüks görülmedi.

Se analizaron los estados financieros, el precio de las acciones así como algunas razones financieras, tomando como muestra las 23 empresas transnacionales que cotizacn en la Bolsa Mexicana de Valores, 15 del sector salud y 8 de telecomunicaciones. Con la información en conjunto se realizaron logaritmos naturales y entre los principales resultados se determinó la rentabilidad en el precio de mercado y el analisis financiero de las compañías con la finalidad de analizar el impacto de la Covid-19.
Una propuesta de medidas integrales para abordar la situación de prostitución en España
Authors: Gutiérrez García Andrea , Delgado Álvarez Carmen
Published: June 2023

La violencia de género ha pasado de ser considerada un asunto privado a entenderse como un problema social que afecta específicamente a las mujeres e implica a toda la sociedad. En diciembre de 2004, tras la tematización de este problema por la tercera ola del feminismo y bajo el impulso de las organizaciones de mujeres, entra en vigor en España la Ley Orgánica de Medidas de Protección Integral contra la Violencia de Género 1/2004 de 28 de Diciembre. Su implementación, no sólo incluyó medidas de prevención e intervención multidisciplinar para erradicar el problema, sino que tuvo un importante efecto pedagógico en la población al deslegitimar esta forma de violencia. La prostitución femenina  hunde sus raíces en la misma estructura patriarcal en la que se asienta la violencia en la pareja, sin embargo carece de una legislación que proteja a las mujeres prostituidas vulneradas en sus derechos humanos, y ponga de manifiesto la violencia contra las mujeres implícita en ella.En este trabajo se expone la necesidad de una ley de medidas integrales contra la prostitución, en base a un análisis psicosocial del problema elaborado previamente. Se toma como ejemplo la Ley Orgánica 1/2004 de medidas de protección integral contra la violencia de género, para elaborar una propuesta justificada sobre las actuaciones que deberían llevarse a cabo a este respecto. Dicha propuesta integral toma como marco de referencia la ley abolicionista instaurada en 1999 en Suecia, pero adaptada al contexto específico español. Se abordan tres cuestiones básicas: educación en igualdad, des-incentivación de la demanda, protección y ayuda a las víctimas. Por último, se hace referencia a la importancia de la no tolerancia social y condena jurídica de las personas que se benefician de la explotación de las mujeres.
Límites de la utilización del concepto “violencia de género” en la Ley Orgánica 1/2004 para actuar contra el acoso sexual
Authors: Marugán Pintos Begoña
Published: June 2023

Lejos de ser neutral, el lenguaje es una de las más poderosas herramientas de actuación política. Conceptualizar es politizar – como mantiene Amorós (2008)- y de ahí el éxito del movimiento feminista al haber conseguido popularizar el concepto de “violencia de género”. Ahora bien, la existencia de un concepto es necesaria para visibilizar el fenómeno, pero insuficiente si se parte de la concepción de Foucault (1992) de que el significado que se concede a los significantes es la resultante del enfrentamiento entre el poder – que trata de mantener el orden existente- y el contrapoder – que puja por introducir cambios-. La teoría feminista se ha mostrado como contrapoder y ha tenido como finalidad, entre otras, la de establecer adecuadas conceptualizaciones (De Miguel, 2003). La revisión del proceso nominal recorrido para visibilizar la violencia contra las mujeres hasta conseguir la cristalización del significante “violencia de género” en la Ley Orgánica 1/2004, de 28 de diciembre, de Medidas de Protección Integral contra la Violencia de Género, permitirá confirmar este hecho. Esta ley institucionalizó el concepto de “violencia de género” sacando a la luz las relaciones de dominación de los hombres sobre las mujeres, sin embargo, limitó su aplicación a la violencia conyugal que sufren las mujeres en las relaciones heterosexuales, dejando fuera otras expresiones de la violencia de género como el acoso sexual. Este aspecto, que tiene serias consecuencias para las víctimas del resto de la violencia sexista – dentro de la cual está el acoso sexual-, permite mostrar el efecto paradójico de cómo el lenguaje, que aparentemente nombra determinadas situaciones, puede encubrir otras. En este caso, el término “violencia de género” ha conseguido mostrar el tipo de violencia relativo a la dominación estructural masculina por parte de la pareja, pero su utilización está ocultando el resto de formas de violencia que las mujeres padecen sólo por el hecho de serlo.
Paralelismos entre terrorismo y violencia machista
Authors: Daza Bonachela María del Mar
Published: June 2023

El estudio de todos los programas de ayudas a víctimas de delitos violentos en España (legislación y literatura científica) revela muy distintos desarrollos en cada ámbito delictivo (terrorismo, otros delitos violentos y contra la libertad sexual, y violencia de género y doméstica), que privilegian extraordinariamente a las víctimas de terrorismo, contrastando con un apoyo muy cicatero a todo el resto. La diferencia de trato a víctimas con el mismo daño es tremenda, y no sólo en aspectos materiales, también en los de reconocimiento y educación social. He indagado qué razones se esgrimen para justificar esa inequidad. La victimización terrorista, dicen, es la del inocente instrumentalizado por antonomasia; implícitamente asignan cuotas de culpa a las demás víctimas, carentes de la idealidad victimal que recibe reconocimiento y apoyo. El patriarcado y sus reformulaciones reaccionarias llevan la milenaria presunción de culpabilidad de las mujeres al extremo, niegan a sus víctimas el reconocimiento, cuestionando su legitimidad para acceder a las escasas medidas de apoyo previstas por la ley, y cuestionan la propia Ley Integral, con efectos funestos. Mientras, las ayudas y apoyos para atender a las víctimas de terrorismo no han cesado de aumentar. Pero al analizar el concepto de terrorismo, sus rasgos definitorios resultan igualmente aplicables al terrorismo machista: es violencia directa, genera dinámicas de terror, tiene intencionalidad política y se ejerce con respaldo de una organización (la mayor de todas, ahí el gran problema). Es preciso un análisis profundo y una mirada global, que atienda equitativamente a todas las víctimas en función del daño recibido y sus necesidades, y se desmarque del populismo penal (punitivismo exacerbado), que englobe a las víctimas, los victimarios y las circunstancias sociales, que centre el foco en la prevención, educación y corresponsabilidad social.
‘Violaciones Consentidas’, una nueva violencia sexual: estudio preliminar. ‘Consented rape’, a new sexual violence: preliminary research
Authors: Cuenca Suárez Sara
Published: June 2023

El presente artículo se basa en una investigación preliminar de carácter cualitativo realizada en torno a las maneras de pensar y vivir las sexualidades, mediante la cual se ha detectado una forma de violencia invisible a la que se ha denominado “Violación Consentida”. El término “Violación Consentida” trata de llamar la atención sobre la violencia estructural e intrapersonal que sufren o experimentan las mujeres cuando acceden a mantener relaciones sexuales sin el componente del deseo.Mediante técnicas como el relato biográfico, la entrevista, el grupo de discusión y el grupo triangular, se busca conocer cómo se viven las “Violaciones Consentidas” e identificar los aspectos sociales que respaldan la aparición de esta violencia. A través de un análisis intergeneracional y cruzado con los diferentes tipos de relaciones afectivas identificadas se alerta de las magnitudes de esta violencia, que llega a estar presente en la totalidad de los discursos recogidos, fruto de los diferentes mecanismos de organización y perpetuación de la sociedad patriarcal. En repuesta al objetivo último de la investigación, que coincide con coadyuvar a una sexualidad saludable, se incluye en el apartado de conclusiones unas líneas de trabajo para su consecución. ABSTRACTThe present article is based on a qualitative preliminary research which focuses in the different thought patterns and ways of living the diverse sexualities. In the research, it has been detected an invisible way of violence which is to be denominated “Consented Rape”. The concept of “Consented Rape” is pretended to bring the attention upon the structural and intrapersonal violence that women suffer or experiment when they agree to perform a sexual intercourse without the desire component of it.With the use of techniques such as biographical reports, interviews, discussion groups and triangular group; the purpose of this article is to understand how these “Consented Rapes” are experienced by the person. It is also another purpose to identify the social aspects that support the emergence of this kind of violence. A crossed intergenerational analysis has been utilised which has involved the different types of identified affective relationships. With this analysis, it seems of big importance the magnitude of this sort of violence which has appeared in all of the personal accounts that have been analysed in this research; and that is related with the different mechanisms of organisation and perpetuation of the patriarchal society. In response to the last objective of this research, which is related to cooperate towards a healthy sexuality, there are some lines of work to its attainment in the conclusions section.

Antonio Caetani (archbishop of Capua, 1566-1624) was a high exponent of anaristocratic Roman family, whose loyalty to the Spanish crown was well known. Hegrew up within the patronage network of the Cardinal Nephew Pietro Aldobrandini,and later moved to that of Scipione Borghese. Thereafter, he became servant ofthree causes: firstly, he pledged obedience to the Pope and to the papal family;secondly, he was vassal of the Spanish crown, and thirdly, he had to serve his ownnoble House. The Caetani’s “triple loyalty” will clearly be proved during hisNunciature of Spain (1611-1618): it had a significant impact on his diplomatic role atthe court of Madrid.

Por medio de sus atenciones materiales a Tiziano, el príncipe Felipe consigue asegurarse la precedencia de sus Poesías sobre otros encargos pendientes, como la importante pintura de la Trinidad (Gloria) para Carlos V. Esta última es la obra encargada en 1551 que el Emperador tendrá que esperar, con paciencia y desconcierto, hasta octubre de 1554, suponiendo, mientras tanto, que el pintor esté muerto.

Method/ology of Phases of Biomarker Discovery
Authors: Navanandan Nidhya , Searns Justin , Ambroggio Lilliam
Published: June 2023

Biomarkers are commonly used in pediatric medicine to identify disease and guide clinical management for children. Biomarkers can be used to predict risk of disease, provide diagnostic clarification, and offer prognostic expectations. Specimens for biomarker testing might require noninvasive collection (eg, urine, exhaled breath) or invasive procedures (eg, blood, bronchoalveolar lavage) and testing might use various methodologies (eg, genomics, transcriptomics, proteomics, metabolomics). Specimen type and testing methodology depends on the disease of interest, ability to obtain sample, and availability of biomarker testing. To develop a new biomarker, researchers must first identify and validate the target, and then determine the test characteristics of the biomarker. Once it has undergone initial development and testing, a new biomarker is then tested in the clinical setting before being implemented into practice. An ideal biomarker is one that is feasible to obtain, readily quantifiable, and offers meaningful information that impacts care. Learning how to reliably interpret the performance and clinical application of a new biomarker is an important skillset for all pediatricians in the hospital setting. Here we provide a high-level overview of the process from biomarker discovery to application. In addition, we provide an example for the real-world application of biomarkers as an opportunity for clinicians to build on their ability to critically evaluate, interpret, and implement biomarkers in clinical practice.

Published: June 2023

BACKGROUND AND OBJECTIVES

Pediatric mental health emergency department (ED) visits are rising in the United States, with more visits involving medication for acute agitation. Timely, standardized implementation of behavioral strategies and medications may reduce the need for physical restraint. Our objective was to standardize agitation management in a pediatric ED and reduce time in physical restraints.

METHODS

A multidisciplinary team conducted a quality improvement initiative from September 2020 to August 2021, followed by a 6-month maintenance period. A barrier assessment revealed that agitation triggers were inadequately recognized, few activities were offered during long ED visits, staff lacked confidence in verbal deescalation techniques, medication choices were inconsistent, and medications were slow to take effect. Sequential interventions included development of an agitation care pathway and order set, optimization of child life and psychiatry workflows, implementation of personalized deescalation plans, and adding droperidol to the formulary. Measures include standardization of medication choice for severe agitation and time in physical restraints.

RESULTS

During the intervention and maintenance periods, there were 129 ED visits with medication given for severe agitation and 10 ED visits with physical restraint use. Among ED visits with medication given for severe agitation, standardized medication choice (olanzapine or droperidol) increased from 8% to 88%. Mean minutes in physical restraints decreased from 173 to 71.

CONCLUSIONS

Implementing an agitation care pathway standardized and improved care for a vulnerable and high-priority population. Future studies are needed to translate interventions to community ED settings and to evaluate optimal management strategies for pediatric acute agitation.
¿CONFINA EL ESPACIO LIBRE A LAS ONDAS Y LAS PARTÍCULAS?
Authors: Castañeda Román
Published: June 2023

En física no-relativística, el espacio libre es considerado desde una perspectiva Newtoniana, es decir, como un escenario uniforme e isotrópico que no interviene en el comportamiento de los entes físicos. En este contexto, la interferencia y la difracción son descritas por la superposición de funciones de onda, lo cual aporta una explicación fenomenológica de esos comportamientos para las ondas, pero sólo provee una estrategia matemática de predicción para las partículas. Se muestra a continuación que la elaboración de una explicación fenomenológica de estos comportamientos, basada en un único principio, conduce a considerar el espacio libre como un ente físico que confina la energía de las ondas y las partículas en pozos Lorentzianos espacialmente estructurados por un potencial geométrico, el cual es activado por una condición de no-localidad preparada sobre la máscara de interferencia. Si esta condición es suficientemente fuerte, los pozos de confinamiento estarán espacialmente entrelazados. También se muestra que difracción e interferencia son términos que denotan modulaciones de confinamiento en diferentes regiones de la banda de frecuencias espaciales. Este desarrollo es puramente teórico, respaldado por modelamiento numérico y reproduce de manera precisa los resultados de experimentos reportados por otros autores.
Investigating the Impact of Online Learning Clubs on Student Motivation and Self-Efficacy in Science: An Experimental Study
Authors: Kersha Yuliya D. , Obukhov Aleksey S.
Published: June 2023

Introduction. Russian studentsʼ natural science literacy lags behind that of their counterparts in other countries, largely due to a lack of interest in the subject area and low self-confidence. Digital technologies offer new opportunities for basic and additional education that can help address these challenges and increase student engagement in the natural sciences. However, not all digital learning formats have been thoroughly examined in terms of their impact on studentsʼ engagement and learning outcomes. This research aims to evaluate the effectiveness of additional online science clubs in enhancing motivation and self-efficacy among schoolchildren in this subject area. Materials and Methods. To investigate the issue, we conducted an experiment involving 1 023 students in grades 7–9 from the Khangalassky ulus of the Republic of Sakha. The experimental group consisted of students randomly selected to participate in online science club on the GlobalLab platform, while the control group continued with regular studies. Using structural equation modelling and instrumental variable methods, we have analyzed data on changes in the level of motivation and self-efficacy of both groups, while also controlling for socio-demographic characteristics and overall curiosity levels of the students. Results. The findings indicate that online clubs have the potential to increase motivation and self-efficacy in natural science subjects, but their widespread use requires further investigation. The comparison of results between the control and experimental groups revealed a slight improvement in both general and subject motivation, as well as subject self-efficacy for students in the experimental group. The instrumental variable approach proved a more significant impact of online club participation on motivation and self-efficacy but only in the specific subject in which the child was engaged. At the same time, the study revealed a rather low interest among students to participate in online science club as extracurricular activity. Discussion and Conclusion. The findings of the study support the notion that online clubs are effective in enhancing studentsʼ motivation and self-efficacy in natural sciences. However, the research also identified certain limitations in the use of additional education outside of school. For instance, students may lack a clear understanding of their participation goals, which can affect their interest in engaging in such activities. Thus, the results of the study provide a basis for evaluating the potential of online formats in additional education and for making recommendations for their optimal use.
Gender Features of Ressentiment among University Students
Authors: Zavrazhin Sergey A. , Kopchenova Lyubov А.
Published: June 2023

Introduction. The relevance of the topic relies on the fact that until now, within the Russian psychological discourse, the problem of gender characteristics of university students’ resentment did not have an autonomous status. The problem of ressentiment in the student environment is poorly developed both at the theoretical and empirical levels. The researchers usually confine themselves to analyzing its individual components (aggression, revenge, resentment, jealousy and envy) and without précising the gender specification of their severity. The purpose of the article is a theoretical and empirical study of the ressentiment constructs characteristic for university students: resentment, revenge, envy, jealousy and aggression, as well as fixing the degree of their manifestation and relationship in the gender projection.
Materials and Methods. The empirical part of the article demonstrates the results of a study on measuring the declared constructs of ressentiment among university students (aggression, revenge, resentment, jealousy and envy) using the following standardized methods: “Buss-Durkee Hostility Inventory (BDHI)” (A. Bass, A. Durkee), “Scales of resentment and vindictiveness” (E. P. Ilyin, P. A. Kovalev), “Multidimensional scale of jealousy” (S. Pfeiffer, P. Wong) and “Methodology for the study of personality envy” (T. V. Beskova). Diagnostic procedures covered 93 people. The questionnaire “Buss-Durkee Hostility Inventory (BDHI)” involves the definition of aggression through the following scales: physical aggression, indirect aggression, irritation and verbal aggression.
Results. Based on the results of an empirical study, the presence of gender characteristics of ressentiment in university students was revealed by fixing differences in the manifestation of the declared constructs: aggression, revenge, resentment, jealousy and envy. It has been established that the dominant constructs of ressentiment among male students are revenge and aggression; while for female students are resentment, jealousy and envy. Ressentiment among students is ambiguous. On the one hand, it has a detrimental effect on the spiritual dimension of the personality and its creative development; on the other hand, it plays the role of a psychological defense mechanism for the individual.
Discussion and Conclusion. The data obtained contribute to the development of scientific ideas about the ressentiment determination in the student environment and the gender characteristics of its manifestation, enrich the psychological and pedagogical knowledge with the methodology for identifying the functional constructs of ressentiment as a destructive form of protecting an individual in an alienated reality. The materials of the article can be useful to specialists in the field of social psychology, preventive pedagogy, deviantology, genderology, enriching them with an understanding of the mechanisms of formation of resentment and gender specificity of its manifestation in the student environment.

O presente estudo investigou o potencial qualitativo de sucos de uvas Concord e Bordô elaborados na região da Campanha Gaúcha. Para tanto, três experimentos foram desenvolvidos, avaliando-se e comparando-se: sucos de uva produzidos em diferentes locais da Campanha Gaúcha (Experimento 1); sucos de uva produzidos na Campanha Gaúcha e Serra Gaúcha (Experimento 2); sucos elaborados por diferentes sistemas de extração (Experimento 3). A qualidade dos sucos foi avaliada por análises físico-químicas e de compostos bioativos. Os fatores que mais influenciaram na qualidade dos sucos dentro da Campanha Gaúcha foram a variedade da uva, o ciclo produtivo e, por último, o local de produção (dentro da região). Os sucos elaborados com uvas provenientes da região da Campanha Gaúcha apresentaram qualidade igual ou superior à daqueles produzidos na região da Serra Gaúcha, de acordo com os parâmetros avaliados. O método de extração do suco impactou na sua qualidade. Sucos elaborados com o uso de enzimas e trocadores de calor tiveram maiores teores de sólidos solúveis e maiores teores de compostos bioativos. Dessa forma, pôde-se concluir que a região da Campanha Gaúcha apresenta condições para produção de sucos de uva ao mercado Brasileiro, atendendo a todos os parâmetros necessários de qualidade avaliados nesse estudo.

This article presents a multifaceted analysis of a painting depicting the image of Nuestra Señora del Rosario from the parish church in Urubamba. The canvas is an unusual work, especially in terms of iconography and in the context of the local rosary cult, which has a very well-established tradition. The painting itself carries a lot of information, the work tells its story through the portraits and inscriptions on it. Thanks to the analysis of the canvas, as well as archival documents, it became possible to reconstruct the context of the work’s functioning.
Soporte tela, pigmentos y moldura como manifestaciones de identidad cultural. Un estudio desde el cuadro San Francisco niño reparte el pan a los pobres (Cusco – Chile, ca. 1668–1684)
Authors:   Universidad de Barcelona, Martínez Victoria Francisca Jiménez
Published: June 2023

This article highlights the importance of applying material and technical studies to the pictorial heritage of Cusco, especially in situations where written accounts of the resources and creative processes involved in its production are limited. Through the analysis of samples of the physical order of the painting San Francisco distributing bread to the poor as a child, exhibited in the Museo Colonial de San Francisco in Santiago de Chile, the material iconological method was used to identify links with the European pictorial tradition and South Andean contributions and inventions. From this specific study, a way is presented by which a series of laboratory examinations focused on recognising the techniques and materials used in viceregal painting can provide valuable information about the context and society that gave them form and meaning.
