Authors: De Uday , Ünal Bülent , Srivastava Sudhir
Published: March 2023

The motive of this work is to investigate pseudo Z symmetric spacetimes. At
first we present some basic properties of pseudo Z symmetric spacetimes
showing that the 1-forms A and B and the scalars a and b associated with the
spacetime agree with a specific relation. Next we explore conditions under
which a pseudo Z symmetric spacetime to be a GRW spacetime and a quasi-Einstein
spacetime respectively. Also we provide some results on pseudo Ricci
symmetric spacetimes.

Published: March 2023

In this paper, a three-species stochastic hybrid Lotka-Volterra system with
distributed delay and L?vy noise is proposed and studied by using
stochastic analytical techniques. First, the existence and uniqueness of
global positive solution with positive initial condition is proved. Then,
sufficient conditions for persistence in mean and extinction of each species
are established. Finally, some numerical simulations are provided to support
our results.

Positive solutions of nonlinear matrix equations via fixed point results in relational metric spaces with w-distance
Authors: Jain Reena , Nashine Hemant , Kadelburg Zoran
Published: March 2023

We consider the non-linear matrix equation (NME) of the form U = Q + ?ki =1A*i ?(U)Ai, where Q is an n?n Hermitian positive definite matrix,A1,A2,...,Am are n?n matrices, and ? is a non-linear self mapping of the set of all
Hermitian matrices which are continuous in the trace norm. We discuss
sufficient conditions ensuring the existence of a unique positive definite
solution of the given NME. In order to do this, we introduce?w-contractive
conditions involving modified simulation functions in relational metric
spaces and derive fixed points results based on them, followed by two
suitable examples. In order to demonstrate the obtained conditions, we
consider three different sets of matrices. Three different types of examples
(including randomly generated matrix and a complex matrix) are given,
together with convergence and error analysis, as well as average CPU time
analysis with different dimensions bar graphs, and visualization of
solutions in surface plot.

Published: March 2023

For A ? L(X), B ? L(Y) and C ? L(Y,X) we denote by MC the operator matrix
defined on X ? Y by MC = (A C 0 B). In this paper, we prove that ?qF(A) ?
?qF(B) ? [ C?L(Y,X) ?qF(MC) ? ?p(B) ? ?p(A?), where ?qF(.) (resp. ?p(.))
denotes the quasi-Fredholm spectrum (resp. the point spectrum). Furthermore,
we consider some sufficient conditions for MC to be quasi-Fredholm and
sufficient conditions to have ?qF(A) ? ?qF(B) = ? C?L(Y,X) ?qF(MC).

Intrahepatic islet transplantation for type 1 diabetes is limited by the need for multiple infusions and poor islet viability posttransplantation. The development of alternative transplantation sites is necessary to improve islet survival and facilitate monitoring and retrieval. We tested a clinically proven biodegradable temporizing matrix (BTM), a polyurethane-based scaffold, to generate a well-vascularized intracutaneous “neodermis” within the skin for islet transplantation. In murine models, BTM did not impair syngeneic islet renal-subcapsular transplant viability or function, and it facilitated diabetes cure for over 150 days. Furthermore, BTM supported functional neonatal porcine islet transplants into RAG-1−/− mice for 400 days. Hence, BTM is nontoxic for islets. Two-photon intravital imaging used to map vessel growth through time identified dense vascular networks, with significant collagen deposition and increases in vessel mass up to 30 days after BTM implantation. In a preclinical porcine skin model, BTM implants created a highly vascularized intracutaneous site by day 7 postimplantation. When syngeneic neonatal porcine islets were transplanted intracutaneously, the islets remained differentiated as insulin-producing cells, maintained normal islet architecture, secreted c-peptide, and survived for over 100 days. Here, we show that BTM facilitates formation of an islet-supportive intracutaneous neodermis in a porcine preclinical model, as an alternative islet-transplant site.

Article Highlights

Human and porcine pancreatic islets were transplanted into a fully vascularized biodegradable temporizing matrix (Novosorb) that creates a unique intracutaneous site outside of the liver in a large-animal preclinical model. The intracutaneous prevascularized site supported pancreatic islet survival for 3 months in a syngeneic porcine-transplant model. Pancreatic (human and porcine) islet survival and function were demonstrated in an intracutaneous site outside of the liver for the first time in a large-animal preclinical model.

Authors: Christensen Maria Hornstrup , Andersen Marianne Skovsager , Rubin Katrine Hass , Nohr Ellen Aagaard , Aalders Jori , Vinter Christina Anne , Jensen Dorte Moeller
Published: March 2023

OBJECTIVE

To investigate associations between previous gestational diabetes mellitus (GDM) and incident psychiatric morbidity, and to explore the role of subsequent diabetes development in psychiatric morbidity risk.

RESEARCH DESIGN AND METHODS

A nationwide register-based cohort study including all women delivering in Denmark from 1997 to 2018 was conducted. GDM exposure was based on diagnosis code, whereas psychiatric morbidity outcome was based on diagnosis code and psychopharmacological medication use. Multiple Cox regression and mediation analyses were performed.

RESULTS

In a study population of 660,017 women, previous GDM was associated with increased risk of depression based on diagnosis code and/or medication use (adjusted hazard ratio [aHR] 1.22 [95% CI 1.18–1.27]), any psychiatric diagnosis (aHR 1.20 [95% CI 1.13–1.27]), and any psychopharmacological medication use (aHR 1.21 [95% CI 1.17–1.25]). Moreover, risk of depressive and anxiety disorders, as well as antidepressant and antipsychotic medication use, was increased, with aHRs ranging from 1.14 (95% CI 1.05–1.25) to 1.32 (95% CI 1.22–1.42). No associations were found regarding substance use disorders, psychotic disorders, bipolar disorders, postpartum psychiatric disease, or anxiolytic medication use. Psychiatric morbidity risk was higher in women with versus without subsequent diabetes development. However, GDM history affected risk estimates only in women without subsequent diabetes. Subsequent diabetes mediated 35–42% of the associations between GDM and psychiatric morbidity.

CONCLUSIONS

GDM was associated with increased psychiatric morbidity risk. Subsequent diabetes development played a significant role in future psychiatric morbidity risk after GDM, although it only partly explained the association.
Goal-Setting Displayed by Vietnamese EFL Students
Authors: Minh Hung Do
Published: March 2023

Goal-setting behavior for learning courses displayed by college students of English as a foreign language (EFL) has yet to be substantively documented in the current literature. The present study, therefore, examined this topic to activate students’ goal-setting behavior in learning, which is deemed to increase their engagement in learning and ability to initiate action plans for goal attainment. The study results also provide pedagogical implications for teachers to tailor their teaching methods, techniques, and course contents in alignment with students’ goals. Thus, the main research questions raised in the study are what goal patterns students set for their specific learning courses and what action plans they make to meet the goals set. For data collecting instruments, an assignment template was completed by 58 EFL students from a university in Vietnam, followed by short phone conversations between the researcher and involved students for self-report validity. The analyzed data results identify three common goal-setting patterns displayed by students and confirm their ability to self-initiate action plans for set goals.
Enhancing Academic Writing Vocabulary Use through Direct Corpus Consultation: Saudi English Majors’ Perceptions and Experiences
Authors: Abdullah Alsehibany Raniya , M. Abdelhalim Safaa
Published: March 2023

Using corpora as a learning tool in Second Language writing has gained popularity recently. The present study aimed to explore how Saudi EFL students perceive and engage with direct corpus consultation activities in academic writing as an effective method of overcoming their vocabulary errors. Hopefully, this study will provide insights into the issue of raising awareness among both EFL university students and writing teachers about the benefits of direct corpus consultation in academic writing, as well as highlighting the potential challenges students might face. Two specific questions were addressed in the study: How do Saudi EFL students perceive direct corpus consultation as a method for overcoming vocabulary errors in academic writing? What are the challenges that EFL students encounter when they use direct corpus consultation? Based on convenience sampling, a total of 32 Saudi female students majoring in English participated in the study. The study employed a mixed-method approach to increase the credibility of the study results. The study data were collected from a structured questionnaire based on a 6-point Likert scale and semi-structured interviews. The corpus used was the Corpus of Contemporary American English. The findings of both the quantitative and qualitative analysis revealed that the participants were positive about using direct corpus consultation to improve vocabulary and academic writing. In addition, some challenges associated with using direct corpus consultation were outlined in the study findings. The study concluded with several recommendations for future research and pedagogical implications.

Authors: Mohamad Maslawati , Mahirah Ab Wahab Siti , Kummin Saadiah
Published: March 2023

The strike of COVID-19 pandemic has affected various sectors tremendously, including the education sector around the globe. This situation has forced the closure of most educational institutions, which include higher learning institutions. Since the Movement Control Order announcement, most teaching and learning processes in higher learning institutions were transferred online. The shift to online learning brings different challenges for teachers in higher learning institutions, including English teachers, regarding technological skills and assessment. In this study, the researchers adopted a multiple case study to explore the strategies of 34 English teachers from nine universities in Malaysia, Indonesia and Maldives to overcome the challenges during Emergency Remote Teaching and Learning. The data was collected through focused group interview sessions, individual open-ended responses via Google Forms and Whatsapp discussion threads. The recorded sessions were transcribed verbatim and analysed using NVIVO software to identify the common categories and themes. The findings showed that the teachers of English overcome problems concerning their technological skills by seeking help from their colleagues, attending courses, training and webinars and choosing suitable platforms for online learning, also conducting better online assessments. The faculty could also provide more webinars, online training, and courses to help teachers to perform better during online learning. This study is believed to shed some light on aspects that need to be considered while planning and executing a meaningful ESL online teaching and learning experience in higher learning institutions, particularly in developing countries.
Efficacy of Problem-Based Learning Strategy to Enhance EFL Learners’ Paragraph Writing and Grammar Skills
Authors: Zannan Alghamdy Rashed
Published: March 2023

Generally, this study investigates the impact of problem-based learning strategies in enhancing and improving English as a Foreign Language students’ paragraph writing skills. It explores the impact of Problem-Based Learning on EFL learners’ paragraph development and grammar abilities. The participants were 38 male students between the ages of 15 and 18. They were all in level ten in secondary school and attended a public learning institution in Al-Baha Saudi Arabia. Data was collected using both qualitative and quantitative approaches. The data collections were post-test and pre-test for the two age-based groups. Qualitative data was collected through video recordings of the participants. The findings from the study revealed that learners perform better in their post-tests compared with the pre-tests regarding grammar skills and paragraph writing. Thus, PBL success affects students’ motivation for improving their paragraph development and grammar skills. This is the reason for the better performances in the post-tests than in the pre-tests. Additionally, the results reveal that EFL students in the control group did not write together as would have expected. The group dynamics that would have been observed through their cooperation with one another were missing during the paragraph-writing activities. Resultantly, they did not share many of their ideas about the activities. A contrast was observed under Problem Based Learning because the students interacted and freely shared their ideas. The learning and progress of each learner were more conspicuous under problem-based learning than in the control group settings.

Published: March 2023

The aim of the research was to analyze and generalize the educational potential of multimodal resources in enhancing students’ motivation in learning English for Specific Purposes. The study was conducted following the theories of digital humanities pedagogy and multimodal pedagogy. It had a descriptive cross-sectional quantitative-based (pedagogical experiment; survey; questionnaire) and qualitative-based (observation of the participants in the educational process; comparison and generalization of pedagogical experience on the problem under research; analysis of the data collected in a statistically accurate manner; monographic method – to interpret the results obtained in a coherent, logical approach) design. The significance of the findings can redound, on the one hand, to modernizing the educational processes of English for Specific Purposes based on the adequate integration of multimodal resources and, on the other, contributing to efficiently developing university students’ multimodal communicative competence. The data collected can be exploited in further research into the issue of increasing the motivation of non-philological students to learn English for professional use. In the course of the pedagogical experiment, effective ways of perceiving and processing the information by students were identified, as well as the advantage of integrating multimodal resources into teaching English for Special Purposes. The scope for further study lies in the in-depth research into forming multimodal communicative competence of technical students in learning English for Specific Purposes.
A Corpus-based Pronunciation Teaching Model: A Conceptual Paper
Authors: Qian Bojie , Diana Deris Farhana
Published: March 2023

Learning a second language is challenging, but mastering pronunciation is even more difficult. Researchers continuously seek new ways to improve students’ English abilities, such as listening and speaking, while ignoring the importance of pronunciation. After conducting a literature review, this article investigates the impact of corpora and two instructional methods on improving students’ pronunciation. The paper addresses how to teach pronunciation effectively in the context of English as a second language. According to the review, corpus resources, critical listening, and shadowing can all be used independently to enhance students’ proficiency in second language learning. Hence, an innovative Corpus-based Critical Listening and Shadowing model has been devised as an aid in the teaching of pronunciation by providing more specific suggestions for teachers and students, with the expectation that students will perform better once they have been taught pronunciation using the methodology. The current study’s findings have pedagogical and methodological implications for pronunciation teaching, learning and research. The implications and future directions of the innovative Corpus-based Critical Listening and Shadowing model are also discussed.

This exploratory paper investigated female gifted secondary school students’ needs for English Learning in Saudi Arabia. It has addressed a gap in the literature regarding English Learning needs analysis of gifted secondary school students in Saudi Arabia. It tries to answer the question: What are the needs of those students? The professional needs for English learning were collected through a need analysis questionnaire addressed to gifted secondary school students in Riyadh, Jeddah, and Al-Baha in Saudi Arabia. The data analysis techniques for the descriptive statistics were frequency count, percentage, means, and standard deviations. The results revealed that gifted students need to learn English primarily to access the vast body of international scientific knowledge and research, to get international certificates in English, and to deal with the media, technology, and the Internet. In addition, this study specified students’ perceptions about the characteristics that should be included in English class, the difficulties they faced while studying language, and their suggestions for better English learning strategies. Furthermore, gifted students preferred to learn English from activities that resemble daily life situations and to learn at their own pace. The research results indicated that gifted students face difficulties in class, such as making mistakes and feeling bored because they already know the information. They have demonstrated a need to insert virtual learning environments into the curriculum. The study recommended that the Ministry of Education enable gifted students to study a tailored gifted curriculum in English and activate enrichment in and out of activities.

‘Look at it beside me’: Ekphrasis and the Illusion of Intimacy in Ciaran Carson’s Still Life (2019)
Authors:   Universidad de Chile, Fernández-Arce Francisca
Published: March 2023

Despite the publication of three books directly addressing the intersection between text and visual artworks — Fishing for Amber (1999), Shamrock Tea (2001), Still Life (2019) — Ciaran Carson’s work has not been given significant attention in terms of his contribution to the subject of ekphrastic poetry in Irish literature. Several texts, on the other hand, have been devoted to discussing his work in relation to the spatial, place-bound quality of his poetry and prose. This article seeks to bridge this gap by reframing the ekphrastic mode as the intimate but illusory coming into contact between author, reader, and work. Using the dual role of the ‘study’ as both a practice drawing and a private room, this paper argues Ciaran Carson’s final collection, Still Life, represents a new interpretation of how intimate connections in domestic spaces can be portrayed in Northern Irish literature.

Estrangement and the Ethics of Attention in Emma Donoghue’s The Wonder
Authors:   University of Zaragoza, Escudero-Alías Maite
Published: March 2023

Drawing upon theoretical frameworks, such as Sara Ahmed’s “strange encounters” (2000), “willful subjects” (2014), and Judith Butler’s vulnerability (2004), the present article aims to explore female agency and action in The Wonder as fundamental steps to achieve transformation and change. For this purpose, I first offer a brief introduction to the vulnerability of the female body in Irish history, as it counts on a significant tradition firmly rooted in religious and class politics. Significantly, the novel foregrounds a reformulation of religious superstitions into new patterns of existence. Lib’s watchfulness and vigil astutely enact a self-displaying activity that offers the promise of a more communicative and empathic interaction with Anna. In addition, attention will be also paid to the narrative techniques that depict Lib’s failure to read Anna’s body fully as a wounded individual, thus revealing an encounter with alterity that can only work when there is will, love and affection. The story, then, challenges an aesthetics of grief and guilt and enacts, in turn, a new pattern of existence for both Anna and Lib. Such a pattern demands an ethics of attention and communication aimed to restore the self and display a more affective stance, which is necessary in order to encounter the limits of intelligibility and find out the perverse truth behind Anna’s “wonderful anomaly” (Donoghue 2016: 97).

The Impact of African Swine Fever (ASF) on Romanian Pig Meat Production: A Review
Authors: Ladoşi Ioan , Păpuc Tudor A. , Ladoşi Daniela
Published: March 2023

The first outbreak of African Swine Fever (ASF) in Romania was recorded in a backyard holding in Satu Mare County in July 2017 as a result of a previous large-scale spread of the virus in wild boars and domestic pig populations in two of Romania’s neighbouring countries, Ukraine and the Republic of Moldova. Since then, more than 1.3 million domestic pigs have been infected in more than 5600 backyard holdings and commercial farms all over Romania where stamping out procedures have been performed afterwards. The spread of the disease could not be contained despite the contingency plans developed by the authorities based on the current EU and Romanian legislation, and currently, the entire territory of Romania is considered to be affected, leading to a significant decline of the pig inventory and major damages in the commercial farming system. Consequently, the amounts of pork imported from other EU member states have increased yearly, pig meat becoming the main commodity on the list of agricultural goods purchased by Romania. 2021 has been by far the worst year for Romanian pig meat production, generating the highest financial losses mainly due to the inability of authorities and policymakers to implement effective and efficient disease control measures.

Authors: Nefedeva Mariia V. , Malogolovkin Alexander S. , Titov Ilya A.
Published: March 2023

Viral individual genes functions and their role in the interaction with the host cells remain the main area in the study of African swine fever virus (ASFV) biology. The extreme heterogeneity of the ASFV makes it difficult to develop vaccines against this pathogen. In this work, we generated the ASFV deletion mutant virus Volgograd/D(1L-5-6L) with the six genes deletion in multigenic family 110 (MGF110) (1L-5-6L) and studied its characteristics in vitro. The homologous recombination method was used for the deletion in ASFV parental strain Volgograd/14с. A series of six passages was carried out in the COS-1 cell culture using the limiting dilution method. The recombinant strain Volgograd/D(1L-5-6L) MGF110 was selected by the plaque formation method. Performed study of viral replication showed no changes in viral growth kinetics in comparison with the parental strain. The ASFV Volgograd/D(1L-5-6L) MGF110 is a great tool available to test the importance of MGF110 for virus virulence and vaccine development.

Published: March 2023

The effects of stress on processes in the body are becoming an increasingly relevant research subject. The reproductive ability of bovine animals largely depends on these effects, whilst embryo transfer is increasingly being used as a reproduction method. In this study, we established the differences in the implantation ability of heifers that were treated (N=17) with selenium (Se) and vitamins AD3E, and non-treated heifers. Upon transfer, we took blood samples from both groups and used the total antioxidant status (TAS) value to analyze the presence of reactive oxygen species (ROS), the levels of non-esterified fatty acids (NEFA) and the levels of vitamin E and Se in blood plasma. In the study, we were able to demonstrate that preventive measures in the form of supplementation of vitamin E and Se, mitigate the effects of oxidative stress, strengthen the ability of an organism to improve the dynamic relationship between free radicals and antioxidants, improve the energy status of cattle, positively impact reproductive parameters and increase the success rate of embryo transfer. The difference in the number of successful embryo implantations between the control and treated group was statistically significant, with 64.7% of treated heifers being pregnant after embryo transfer and giving birth to healthy calves. In the control group, the implantation success rate was 41.2%. The supplementation of antioxidants in the form of a combination of vitamin AD3E and Se, proved to be a good method for strengthening the defense of an organism and an effective mean of preventive clinical approach for improving fertility parameters.
Orthovoltage X-Ray Therapy of Large Cell Invasive Nasal Lymphoma in Cat
Authors: Rogachev Alexander , Gazin Alexey , Zuenkova Yuliia
Published: March 2023

Feline nasal lymphoma is generally a localized radiosensitive tumor. Treatment options include radiation therapy, chemotherapy, or a combination of both modalities. Radiation therapy (RT) in a combination with chemotherapy lead to median survival from 19 months to 955 days. The objective of this paper is to report a case of a large cell late stage invasive feline nasal lymphoma and to evaluate the results of orthovoltage radiation therapy and its side effects. A 12-year-old female mixed breed cat was presented with nasal discharge, sneezing and hyporexia. Definitive histopathology diagnosis was diffuse large cell lymphoma. Computed tomography revealed an advanced stage of the disease, an intranasal mass, bone lysis, invasion of the orbital space and central nervous system. A radical course of X-ray therapy was performed (SFD = 4 Gy, TSD = 40 Gy, 10 sessions, 3 times a week). Radiation side effects were well tolerated and resolved with supportive treatment. Lymphoma is a systemic process and requires a multidisciplinary approach. On most cases, the penetrating ability of radiation therapy of 3.5 cm in depth is enough for small domestic animals. A significant effect is noted in the middle of the treatment course. The fractionated regime did not cause early radiation damage. The relapse-free period was up to 8 months. The patient had a satisfying quality of life for 5 months. Orthovoltage X-ray therapy can be considered as a treatment choice for local nasal lymphoma. X-ray therapy is a widely used modality in veterinary medicine considering the price of machines and costs of treatment.

Heat stress (HS) is an environmental challenge affecting animals’ health, productivity and welfare. This work aimed to inspect the protective effect of zinc oxide nanoparticles (ZnNPs) and/or prodigiosin (PRG) against inflammation, immune dysfunction, oxidative stress and endoplasmic reticulum (ER) stress triggered by HS in growing rabbits. Growing weaned rabbits (one hundred males, 35 days of age) were randomly assigned into four groups. The first group was fed a basal diet without supplementation and the 2nd, 3rd, and 4th groups were fed diets containing zinc oxide nanoparticles (ZnNPs, 50 mg/kg diet), prodigiosin (PRG, 100 mg/kg diet) or their mixture (ZnPRG) under HS conditions for eight successive weeks. The dietary inclusion with ZnNPs and/or PRG significantly boosted FBW (final body weight), CBWG (cumulative body weight gain), and FCR (feed conversion ratio) and had no substantial impacts on the CFI (cumulative feed intake) as compared with those in HS one. All supplemented treatments significantly unveiled an increase in the values of RBCs, hemoglobin, and platelets and significant decreases in WBCs, basophils and monocytes with non-statistical effects on hematocrit, MCV, MCHC, neutrophils and eosinophils. Compared with the HS group, all supplemental groups showed a significant reduction in TNFα, IL4, IFN-γ, TLR-4 and amyloid A levels and DNA damage markers (OHdG) and significant increases in the levels of NO and lysosome activity. Rabbits in the ZnPRG group had significantly higher IgG and IgM levels compared to other groups. The highest value of CAT and GSH levels were found in rabbits that received the mixture of ZnNPs (50 mg) and prg (100 mg) in their diets under elevated temperatures. Additionally, both treatments, PRG and ZnNPS, significantly (P<0.001) reduced the values of MDA and MYO, while all treated groups had significantly reduced PC contents compared with the HS group. Co-supplement with ZnPRG showed a considerable restoration in the higher immune expression of reticulum oxidative stress such as GRP78 and IRE1 in hepatic tissues induced by hs conditions. The mixture of ZnNPS and prg presented more robust effects in mitigating the adverse impacts of hs in rabbits compared with the individual treatments. Collectively, ZnNps and/or PRG alleviated oxidative stress and dna damage. In addition, it enhanced the antioxidant capacity and immune function, and downregulated ER stress such as GRP78 and IRE1 signaling in the hepatic tissues of stressed rabbits.

Introduction

Among large wild game in Poland, the most numerous cervids are red deer and roe deer. Although these species live free, they should be under veterinary supervision because they can transmit infectious agents and parasites to livestock. The aim of this study was to evaluate the biodiversity of the abomasal nematodes which parasitise cervids and present the visual and dimensional characteristics of their spicules.

Material and Methods

Overall, 2,067 spicules of nematodes derived from nine red deer and five roe deer were measured and microphotographed in order to determine the species. The predominant Spiculopteragia boehmi was additionally confirmed molecularly by PCR. The spicule lengths of the most common species found in both hosts simultaneously were compared.

Results

Fourteen species of abomasal nematode were identified. All examined animals but one were infected. The most prevalent parasites in both host species were S. boehmi and Ostertagia leptospicularis. The alien Ashworthius sidemi was found in both hosts, whereas Haemonchus contortus was identified only in red deer. Mazamastrongylus dagestanica was noted in red deer for the first time. A 262-base-pair nucleotide sequence of S. boehmi was obtained and deposited in GenBank. Significantly longer spicules were found in red deer-derived O. leptospicularis and S. boehmi and shorter structures were seen in A. sidemi.

Conclusion

The widespread exchange of abomasal nematodes between various ruminant species questions the relevance of their division into specialists and generalists.

A avaliação da pós-graduação stricto sensu no Brasil é realizada pela Coordenação de Aperfeiçoamento de Pessoal de Nível Superior e constitui instrumento fundamental do sistema nacional de pós-graduação. Os resultados da avaliação têm diversos usos. Para o cumprimento dos itens e quesitos avaliativos e para a prestação das informações requeridas pelo processo de avaliação, docentes e coordenadores/as de cursos stricto sensu trabalham sob a demanda por produtividade em um contexto no qual todos precisam contribuir, pois o fecho deste trabalho em grupo é expresso pelo resultado da avaliação quadrienal do programa de pós-graduação. Deste modo, o ponto que se apresenta é a averiguação do trabalho docente sob conjuntura coletiva. Nesta perspectiva, refletir sobre as características, natureza, estrutura, papéis dos integrantes e propósitos de um grupo torna-se o objetivo deste estudo e, para isso, recorrem-se aos estudos de Michener et al. (2005) e suas contribuições sobre ‘Grupos’. Os pontos de confluência sobre as questões que envolvem ‘Grupos’, a partir da obra do referido autor, são apresentados ao longo do texto, acompanhados de resultados e discussões de pesquisas recentes realizadas no Brasil para demonstrar as situações práticas e aclarar a teoria.
Educação secundária e formação para o trabalho
Authors: Pereira Estela
Published: March 2023

Este artigo aponta aspectos da recente reforma educacional espanhola, relativos à educação secundária, que são coincidentes com orientações presentes na reforma do ensino médio brasileira, e propõe uma reflexão sobre as relações entre educação e capital. Não se trata de estudo comparativo, mas do esforço de identificação das proposições e justificativas presentes nas duas reformas que anunciam, em comum, o propósito de adequar a força de trabalho às novas demandas produtivas e laborais. Nesse processo, observa-se a participação efetiva do empresariado nas decisões sobre os sistemas educacionais. Para além dos interesses nos fundos públicos e no ajustamento da oferta formativa aos propósitos do capital, busca-se compreender intencionalidades e mecanismos presentes nas reformas, segundo os conceitos de “segmentação” e “sistematização” apresentados por Ringer e Müller. Ao investigarem o processo de implementação da educação secundária em países europeus no contexto de industrialização, os autores destacam a vinculação de sistemas educacionais aos interesses de manutenção e reprodução de classes, por meio de ofertas distintas e fragmentadas. Dos sistemas por eles estudados, destacamos o alemão, que é considerado uma referência para sistemas europeus, inclusive para o espanhol, aqui abordado.

Accident rate of ships with nuclear power plants of foreign fleets
Authors:   Krylov State Research Centre, St. Petersburg, Russia, Polovinkin V.N.
Published: March 2023

Предметом монографии является аналитический обзор информации об аварийности кораблей с ядерными энергетическими установками (ЯЭУ) военно-морских сил (ВМС) иностранных флотов. Серьезную озабоченность у руководства ВМС зарубежных стран, где эксплуатируются корабли с ЯЭУ, вызывают аварийные происшествия с ними, особенно инциденты, которые приводили или могли привести к нарушению условий обеспечения ядерной, радиационной и экологической безопасности и тем самым нанести политический ущерб государству. В связи с этим командование ВМС допускает дозированный характер публикаций в печати об имевших место происшествиях и авариях боевых кораблей с ЯЭУ, однако полностью скрывать подобную информацию не удается. Выполненный анализ сообщений зарубежной печати позволяет сделать вывод, что иностранные ПЛА и надводные боевые корабли с ЯЭУ наряду с другими военными кораблями ВМС не смогли избежать аварий технического характера (пожары, взрывы, затопления, разрушения энергетического и корабельного оборудования и др.), а также морских происшествий (посадки на мель, удары о грунт, столкновения с препятствиями и др.), в т.ч. связанных с ошибками в управлении кораблем либо с воздействием экстремальных гидрометеорологических факторов. Результаты исследования, представленные в монографии, могут быть использованы специалистами в области проектирования, испытаний и эксплуатации систем корабельных ЯЭУ, в частности при обосновании требований и подготовке тактико-технических заданий на создание реакторного и энергетического оборудования для перспективных кораблей с ЯЭУ. Монография предназначена для широкого круга читателей и может быть полезной слушателям и преподавателям в образовательном процессе высших учебных заведений (в т.ч. специализированных), а также специалистам, осуществляющим научно-исследовательскую деятельность.
