The development of compounds with a better antibacterial activity is highly needed. One way to achieve this is by modifying the structure of the compound using chitosan as a starting material, because of its abundant natural source in Indonesia, its biodegradable properties, and its structure where free amines are present. This study aims to obtain  Mn(II) -Carboxymethyl Chitosan Schiff Base-Salicylaldehyde complex to increase its antibacterial activity against Staphylococcus aureus (Gram positive) and Escherichia coli (Gram negative). Schiff Base carboxymethyl chitosan-salicylaldehyde was synthesized from carboxymethyl chitosan with salicylaldehyde. Next, the Schiff Base Carboxymethyl Chitosan-Salicylaldehyde was complexed with MnCl2.4H2O and then characterized by FTIR, UV-Vis Spectrophotometer, and AAS and tested for antibacterial activity with the disc diffusion method against Staphylococcus aureus and Escherichia coli. The product of Carboxymethyl Chitosan Schiff Base-salicylaldehyde is a brownish yellow solid with a yield of 64% (w/w) and has antibacterial activity against Staphylococcus aureus (clear zone diameter 11 mm) and Escherichia coli (clear zone diameter 13 mm). The product of Mn(II) Complexes-Carboxymethyl Chitosan Schiff Base-salicylaldehyde is a black solid with a yield of 59% (w/w) and has antibacterial activity against Staphylococcus aureus (clear zone diameter 13 mm) and Escherichia coli (clear zone diameter 17 mm).

OBJECTIVES

Rotavirus vaccination has 87% to 100% effectiveness against severe rotavirus acute gastroenteritis (AGE) in healthy infants in high-income countries. Little is known whether infants with medical risk conditions (MRCs) are equally protected and if the vaccine is equally well tolerated. We conducted a quasi-experimental prospective multicenter before-after cohort study to assess the vaccine effectiveness (VE) and safety profile of the human rotavirus vaccine (HRV) among MRC infants that required prolonged or frequent postnatal care.

METHODS

The Netherlands has no national rotavirus immunization program, but HRV was implemented in routine care for MRC infants in 13 Dutch hospitals. Participants in the before and after cohort, HRV unvaccinated and vaccinated, respectively, were followed for occurrence of (rotavirus) AGE. VE of at least 1 dose was estimated by using time-to-event analysis for severe rotavirus AGE. Vaccine-related serious adverse event (AEs) after HRV were retrieved systematically from medical charts. Solicited AEs after vaccinations were prospectively collected and compared between vaccination time points with or without HRV.

RESULTS

In total, 1482 high-risk infants with MRC were enrolled, including 631 in the before and 851 in the after cohorts; 1302 infants were premature (88.3%), 447 were small for gestational age (30.2%), and 251 had at least 1 congenital disorder (17.0%). VE against severe rotavirus AGE was 30% (95% confidence interval [CI]: −36% to 65%). Overall, the observed number of rotavirus hospitalizations was low and not significantly different between the cohorts (2 and 2, respectively). The rate of vaccine-related serious AE was 0.24 per 100 vaccine doses. The adjusted risk ratio for any AE after HRV vaccination compared with other routine vaccinations was 1.09 (95% CI: 1.05 to 1.12) for concomitant administration and 0.91 (95% CI: 0.81 to 0.99) for single HRV administration. Gastrointestinal AEs were 10% more frequent after HRV.

CONCLUSIONS

In contrast to previous findings among healthy term infants, in routine use, HRV offered limited protection to vulnerable medical risk infants. HRV is generally well tolerated in this group in single administration, but when coadministered with routine vaccines, it is associated with higher risk of (mostly gastrointestinal) AE. Our study highlights the importance of studying vaccine performance in subgroups of medically vulnerable infants.

BACKGROUND

We previously demonstrated that a hand hygiene program, including hand sanitizer and educational measures, for day care center (DCC) staff, children, and parents was more effective than a soap-and-water program, with initial observation, in preventing respiratory infections (RIs) in children attending DCCs. We analyzed the cost-effectiveness of these programs in preventing RIs.

METHODS

A cluster, randomized, controlled and open study of 911 children aged 0 to 3 years, attending 24 DCCs in Almeria. Two intervention groups of DCC-families performed educational measures and hand hygiene, one with soap-and-water (SWG) and another with hand sanitizer (HSG). The control group (CG) followed usual hand-washing procedures. RI episodes, including symptoms, treatments, medical contacts, complementary analyses, and DCC absenteeism days, were reported by parents. A Bayesian cost-effectiveness model was developed.

RESULTS

There were 5201 RI episodes registered. The adjusted mean societal costs of RIs per child per study period were CG: €522.25 (95% confidence interval [CI]: 437.10 to 622.46); HSG: €374.53 (95% CI: 314.90 to 443.07); SWG: €494.51 (95% CI: 419.21 to 585.27). The indirect costs constituted between 35.7% to 43.6% of the total costs. Children belonging to the HSG had an average of 1.39 fewer RI episodes than the CG and 0.93 less than the SWG. It represents a saving of societal cost mean per child per study period of €147.72 and €119.15, respectively. The HSG intervention was dominant versus SWG and CG.

CONCLUSIONS

Hand hygiene programs that include hand sanitizer and educational measures for DCC staff, children, and parents are more effective and cost less than a program with soap and water and initial observation in children attending DCCs.
Promoting the Participation of Children and Adolescents With Disabilities in Sports, Recreation, and Physical Activity

Published: November 2021

The benefits of physical activity are likely universal for all children, including children and adolescents with disabilities (CWD). The participation of CWD in physical activity, including adaptive or therapeutic sports and recreation, promotes inclusion, minimizes deconditioning, optimizes physical functioning, improves mental health as well as academic achievement, and enhances overall well-being. Despite these benefits, CWD face barriers to participation and have lower levels of fitness, reduced rates of participation, and a higher prevalence of overweight and obesity compared with typically developing peers. Pediatricians and caregivers may overestimate the risks or overlook the benefits of physical activity in CWD, which further limits participation. Preparticipation evaluations often include assessment of health status, functional capacity, individual activity preferences, availability of appropriate programs, and safety precautions. Given the complexity, the preparticipation evaluation for CWD may not occur in the context of a single office visit but rather over a period of time with input from the child’s multidisciplinary team (physicians, coaches, physical education teachers, school nurses, adaptive recreation specialists, physical and occupational therapists, and others). Some CWD may desire to participate in organized sports to experience the challenge of competition, and others may prefer recreational activities for enjoyment. To reach the goal of inclusion in appropriate physical activities for all children with disabilities, child, family, financial, and societal barriers to participation need to be identified and addressed. Health care providers can facilitate participation by encouraging physical activity among CWD and their families during visits. Health care providers can create “physical activity prescriptions” for CWD on the basis of the child’s preferred activities, functional status, need for adaptation of the activity and the recreational opportunities available in the community. This clinical report discusses the importance of participation in sports, recreation, and physical activity for CWD and offers practical suggestions to health care providers.

Serological controls for diseases of viral origin in animal production systems and the identification of factors associated with infections are decisive elements to establish prevention and control measures. The aim of this study was to establish the serological status for Bovine Viral Diarrhea (BVD) and Enzootic Bovine Leukemia (EBL) viruses in Blanco Orejinegro (BON) cattle from Colombia, and to identify the factors associated with seropositivity. A cross-sectional study was conducted with a total of 498 animals of all age groups and physiological states of the BON breed were selected, belonging to 14 herds located in 6 states of Colombia, in which a survey with 27 questions was conducted. By means of the chi-square test, possible factors associated with seropositivity against the 2 viruses were identified. A sample of 4 ml of blood was taken from each animal to extract plasma and make indirect Elisa tests to detect antibodies against both pathogens. General seropositivity of 27,1% was obtained for EBL, finding as factors associated with seropositivity the inadequate disposition of placental tissues after delivery of the cows and the non-performance of serological tests on new animals entering the herd. For BVD, seropositivity obtained was 50,6%, and the factors associated with seropositivity identified were having had a history of the disease in the herd, and using semen from bulls that are not known to be free for the infection. We suggest establishing control measures considering the factors associated with each viral infection to limit their expansion in the BON cattle production systems of Colombia.

Published: November 2021

Viticulture is one of the priorities of European agricultural policy. The sale of wine is successful when the product offered is competitive in the relevant market. The qualities of wine as a specific product are determined by the following factors - grape variety, wine taste, ecology of the region, wine production technology, etc. In this sense, Bulgaria has all the prerequisites for being among the leading wine producers in Europe and in the world. Our country has a tradition in the vine and wine sectors, in which funds continue to be invested. This is the main reason for the study to be focused on the wine market.
The main objective of the scientific research paper is to outline the role of wine production in Bulgaria and to study sales in one of the wine regions - North Central.
The subject of the study is the producers from the wine-growing region, members of the National Vine and Wine Chamber. In this regard, the survey was conducted in four of the seven companies, namely: Vinal AD., Lovech; Winery Pleven EAD, Pleven; Winery Svishtov AD., Svishtov and Loviko Lozari, Suhindol.
The object of the study is the market indicators of the wine producers in the selected region. These indicators are being summarised and analysed. In conclusion, trends are outlined and recommendations for improving the efficiency of the surveyed enterprises in the sector are derived.

Authors: Midova P.
Published: November 2021

The interest in the subsector Wine production is caused, on the one hand, by the growing competition and the rapidly developing world market of wine products, characterised by an increase in consumption and export. On the other hand, the interest in the market continues to grow due to the importance of the subsector for our country.
The main objective of this paper is to study the leading winemakers in the South Central Region of Bulgaria. In this regard, some indicators for the activity of the studied 15 wine production enterprises are derived. In particular, three leading market criteria are covered - net sales revenue, sales revenue per employee and relative market share.
Based on an analysis of market indicators, conclusions are drawn and trends for the development of wine production in the studied region are presented.
LOCAL CONSUMPTION OF AGRICULTURAL PRODUCTS IN BULGARIA
Authors: Aleksiev G.
Published: November 2021

Bulgarian agriculture has undergone several transformations at the end of the 20th and the first two decades of the 21st century. The ever-increasing use of modern technology has led to the concentration of production with a focus on oil seeds, corn, wheat, and other cereals. This form of development of the sector has led to the dependence on food imports for some of the major food groups.
The goal of this study is to analyze the local consumption of agricultural products in Bulgaria in order to draw a conclusion on any discrepancies between food supply and demand in the country. To achieve its goal, the study must focus on a few important topics: to analyze the food production structure in the country; to study the local consumption of agricultural products; to draw conclusions and offer development policies focused on sustainability.
ENGLISH TEACHERS’ PERCEPTIONS OF STUDENT EVALUATION OF TEACHING IN AN INDONESIAN UNIVERSITY
Authors: Silalahi Rentauli Maria
Published: November 2021

Student evaluation of teaching (SET) has been proven to improve teachers’ teaching practices and students’ learning experiences despite being used commonly for accountability purposes. Indonesian teachers’ perceptions of SET, however, remain largely unexplored. This qualitative study therefore investigated how four Indonesian university teachers perceived SET, how SET impacted their teaching practices and what roles they believed the university should play in implementing SET properly. The participants taught English to undergraduate students in an Indonesian private university. Data were collected using semi-structured interviews and analysed using qualitative methods. The teachers perceived SET positively, had made conscious changes to improve their teaching practices and students’ learning, and believed the institution had facilitated teachers in meeting students’ needs, especially during the campus closure due to the COVID-19 pandemic, which led to a transition to online learning. The institution where the participants taught implemented SET only for formative or improvement purposes. Using SET for such purposes is important as it is more likely to cause teachers less pressure and anxiety. Hence, teachers are willing to act upon the student feedback. Meanwhile, using SET for accountability purposes may create extra work for teachers and make them feel manipulated and untrusted.
TEACHING FACTORS THAT AFFECT STUDENTS’ LEARNING MOTIVATION: BANGLADESHI EFL STUDENTS’ PERCEPTIONS
Authors: Quadir Moriam
Published: November 2021

Research literature consistently suggests that EFL (English as a foreign language) students’ motivation is affected by some teaching factors (Falout et al., 2009; Kim et al., 2018; Lamb, 2017). The main purpose of this study is to identify exactly which teaching factors adversely affect students’ motivation to study English at higher secondary (HS) level (grade 11 and 12) in Bangladeshi EFL context. To collect qualitative data an interview protocol was developed based on the teaching factors identified in some selected studies conducted in Asian EFL contexts (Kikuchi, 2009; Sakai & Kikuchi, 2009; Trang & Baldauf, 2007; Quadir, 2017). A total number of 40 grade 12 completers were interviewed to collect students’ perceptions. Miles and Huberman’s (1994) qualitative data analysis procedure was applied to analyze the data. From the analysis five distinct factors, which adversely affect students’ motivation, are identified in descending order: teachers’ instructional styles and teaching method, private tutoring, teachers’ personality and behavior, teachers’ competence and classroom management, and teachers’ attitude and commitment. Most of these factors comprise further sub-components which detect the underlying sources of students’ disinterest. For amelioration of the situations some feasible implications are discussed addressing the identified factors.

This article reports on a study investigating the perceptions of EFL teachers in schools and language courses (henceforth, teachers) and EFL lecturers in tertiary educational institutions (academic staff) from Indonesia regarding their definitions of and their engagements in teacher research. An online questionnaire was used to gather quantitative data from almost 400 EFL teachers and academic staff from Indonesia. The questionnaire was followed by in-depth interviews with some respondents who met the criteria set and agreed to be interviewed. Results from the study show that both teachers and academic staff align research with evidence-based practice, survey, literature-driven practice and professional communication, and observation-based popular article. In terms of engagements, most of the teachers and academic staff read research papers occasionally, and more academic staff did research compared to teachers. Research done by both teachers and academic staff is largely associated with internal and external factors, such as, professional awareness and professional obligation, with academic staff seem to receive more support to engage in research. The findings of the study provide insights for future continuous professional development (CPD) activities for English teachers and academic staff. The activities might involve exploring ways to integrate teacher research into teachers’ and academic staff’s teaching responsibilities and integrating teacher research into the short-term and long-term goals of CPD.

Published: November 2021

ABSTRACT In the context of plant breeding programs, it is necessary to evaluate the efficiency of genotype selection over successive years. However, evaluating the genotype selection efficiency is not an easy task, since there is not just a single way to precede it. Besides that, the programs need to be dynamic; that is, they should be able to track the introduction and discard of genotypes each year. As a result, the available data is quite unbalanced, leading to difficulties in certain analyses. Thus, the present study aims to propose some approaches to verify the genetic progress in the preliminary trial of the Federal University of Lavras (UFLA) upland rice breeding program. We utilized mixed models for grain yield and plant height. Trials were performed with a total of 120 genotypes in seven environments, defined by the interaction between locations and years. Due to the imbalance in the available data, the mixed model approach, i.e., Restricted Maximum Likelihood/Best Linear Unbiased Prediction (REML/BLUP), was adopted for the joint analysis. Besides the genetic and phenotypic parameters, the expected gains were also obtained with the selection, genetic progress, renewal rate (RR%), and dynamism of preliminary trials. The efficiency of the selection of superior genotypes per year was verified, with genetic progress favorable for reducing the medium-sized plants associated with high yield.

Abstract: Elasmobranchs exhibit the biggest population declines among vertebrates, being considered one of the groups with the highest risk of extinction. The Brazilian Amazon Coast (BAC) is considered a priority area for elasmobranch conservation, as many species are endemic to the region, and most of them are threatened with extinction. The present study made a scientometric analysis using the IRAMUTEQ method (Interface de R pour les Analyses Multidimensionnelles de Textes et de Questionnaires) to evaluate the trends of research with elasmobranchs in BAC in the last four decades. Ten research trends were identified, highlighting “Biodiversity”, “Reproduction”, “Trophic Ecology” and “Conservation”. However, most of the publications found are aimed at understanding the diversity and abundance of species in the region, with the number of studies focused on reproduction, feeding and other aspects of the biology and ecology of elasmobranchs in the BAC being less expressive. Although the research area “Conservation” stood out in the search, the amount of relevant information so that management and conservation measures can be implemented is still low. Lastly, despite following the global trend of studies with elasmobranchs between 2000 and 2010, investigations into the BAC need to advance, especially considering the poor level of basic information on most species (Biology and population dynamics) and the incomplete knowledge of specific composition of elasmobranch species in the entire area, aspects relevant to conservation and more applied studies that rely on more recent methodologies and technologies.

Nesta contribuição, apresentamos um tema avançado de grande relevância na Física: a quebra espontânea de simetria – fundamental para o chamado Mecanismo de Higgs – numa abordagem adequada ao ensino médio. O modelo matemático da quebra de simetria é abordado a partir da analogia entre os osciladores harmônico simples e anarmônico. Na sequência, discutimos como a massa física do bóson de Higgs surge a partir da oscilação da coordenada oscilatória de Higgs, aqui desempenhando o papel do campo de Higgs. Também propomos o uso de simulação computacional, utilizando o software Modellus , para estudar a energia dos osciladores. O objetivo de propor a simulação é tornar a aprendizagem mais eficiente e aumentar o protagonismo do aluno.

Resumo: O abandono escolar ainda é uma realidade no Brasil, principalmente no meio rural. Políticas públicas que possam reduzi-lo, mesmo que indiretamente, são importantes. Assim, este trabalho avaliou o impacto da aposentadoria rural, benefício que pode transbordar seus efeitos em diversos fatores socioeconômicos, sobre o abandono escolar. A partir da descontinuidade gerada pela idade mínima para o acesso à aposentadoria rural, foram estimados modelos de regressão com descontinuidade utilizando os microdados do Módulo de Educação da PNAD de 2019 para uma amostra de domicílios rurais brasileiros. Os resultados, que para a amostra completa não foram significativos, revelaram impacto negativo e significativo da aposentadoria rural sobre o abandono aos garotos, principalmente na presença de pensionistas homens no domicílio. Esse efeito não foi observado para garotas. Essas evidências apontaram vieses possivelmente originados por expectativas associadas ao gênero dos jovens, nas quais os garotos deviam se preparar para o mercado de trabalho, enquanto as garotas deviam contribuir com os afazeres domésticos. Dessa forma, os resultados indicaram o potencial efeito redutor da aposentadoria rural sobre o abandono escolar de jovens no meio rural, tendo consequências positivas ao capital humano brasileiro, ainda que se exijam soluções que evitem o aumento na desigualdade de gênero.
Development of new adjusted equations to estimate the skeletal muscle mass stratified by nutritional status for patients with rheumatoid arthritis: a methodological study

Published: November 2021

Abstract Our objective was to adjust and validate predictive equations for appendicular skeletal muscle mass (ASM) in patients with Rheumatoid Arthritis (RA). Whole-body DXA data in 90 RA patients were used for measurement of ASM (kg). The prediction equation anthropometric for muscle mass proposed by Lee et al was used to generate estimates of ASM. Appendicular skeletal muscle mass index (ASMI, kg/m2) was calculated. Frequency analysis, Paired student's t-test, Linear regression, Pearson correlation, Intraclass correlation coefficients, and Bland-Altman scatter were performed. The statistical significance considered was p<0.05. Lee’s equation was overestimated by 30% when compared with ASMI by DXA. When stratified by nutritional status, Lee’s equation overestimated the ASMI by 30% in overweight patients and by 50% in obese patients when compared with DXA (p<0.05). These adjusted equations estimated values for ASMI were closer to those obtained by DXA than those estimated by the original Lee’s equation (p<0.05). This greater concordance was confirmed by the observed interclass correlation coefficients and by Bland-Altman scatter graphs. In conclusion, the prediction of muscle mass in RA patients may be performed with equations that consider the nutritional status of patients.
O teletrabalho na pandemia da covid-19: uma nova armadilha do capital?

Published: November 2021

Resumo Este artigo tem por escopo discutir o fenômeno do teletrabalho, que foi impulsionado em razão do contexto da pandemia do Covid-19 em 2020. Destaca-se a nova narrativa do capital, que, ao tempo que exalta seus benefícios, tende a ocultar os riscos, bem como as possibilidades de reformulação dos ganhos empresariais na exploração do trabalho humano. Para tanto, revisa-se o novo cenário do trabalho, a partir do contexto da denominada “modernização” das relações laborais, considerando os processos de intensificação das jornadas, de apropriação do espaço privado da residência dos trabalhadores, de compatibilização entre trabalho produtivo e reprodutivo, sobretudo por mulheres, de isolamento em relação aos coletivos de trabalho e suas articulações políticas, bem como de sofrimento e adoecimento psíquico. A partir de bibliografia pertinente e da análise de dados secundários sobre o teletrabalho na atualidade, é problematizada a regulação incidente sobre esses trabalhadores como elemento conformador do fenômeno.

Published: November 2021

Abstract This article proposes a retrospective look at the last year following the World Health Organization’s declaration of Covid-19 as a pandemic, and seeks to reflect the wide diversity of its impact. In reviewing research from around the world, a panorama emerges showing the vast complexity of the phenomenon. This article reviews many of the analyses and debates that have been proposed from the framework of political philosophy, which are drawn almost exclusively from the European context. It shows that the suggested diagnoses, models and concepts cannot be universally applied across geographies, such as Latin America, Asia or Africa. It therefore proposes to “deglobalize” the Covid-19 pandemic and invites the reader to consider it through another lens.
“Falta de fechamento”: conflitos profissionais e centralidade dos procedimentos de segurança no sistema socioeducativo do Rio de Janeiro
Authors: Vinuto Juliana , Vargas Joana Domingues , Gonçalves Hebe Signorini
Published: November 2021

Resumo No intuito de compreender as relações entre os objetivos considerados como inconciliáveis por profissionais que atuam na medida socioeducativa de internação, este artigo analisará as discussões sobre falta de fechamento, categoria mobilizada por agentes de segurança socioeducativa para indicar a disjunção e a desconfiança entre diferentes grupos profissionais. A partir de experiências diversas de pesquisa, será possível constatar que os conflitos em torno da falta de fechamento revelam um contexto organizacional em que cada grupo pode fazer o trabalho do modo como considera mais adequado, sem prestar contas uns aos outros, o que permite que aqueles que atuam de modo dissociado dos discursos oficiais nem sempre sejam responsabilizados por isso. Tal contexto ajuda a compreender a produção cotidiana da centralidade atribuída aos procedimentos de segurança na medida socioeducativa de internação, já que as atividades socioeducativas só são implementadas quando não conflitam com os objetivos de controle e disciplina ou em ocasiões em que a instituição tenta auferir algum lucro simbólico a partir da perspectiva socioeducativa.

Nas análises ajustadas, ‘carnes’ foi inversamente associado à circunferência de cintura (ß=-1,52 - IC95% -2.66;-0,39), índice de massa corporal (IMC) (ß=-0,56 - IC95% -1,01;-0,11) e escore de risco de Framingham (ß=-0,36 - IC95% -0,64;-0,09). Conclusão Diante do excesso de peso, risco de doenças cardiovasculares e associação inversa entre o padrão alimentar ‘carnes’ e o IMC, tornam-se importantes novas investigações em populações não trabalhadoras, visando melhor compreender o processo saúde-doença relacionado ao consumo alimentar.
Nonlinear heating system of modular-trigger and platform furnaces for firing bulk materials
Authors: Nizhegorodov A. I.
Published: November 2021

The design of the suspended nonlinear heating system of modular-trigger and platform furnaces for firing vermiculite and other bulk materials is considered. Previously, the design of linear heating systems did not provide homogeneous heating of thermographed materials, the material in the clutch zones suffered sufficient thermal energy. In addition, overheating of the central zone increased the frequency of the impact of the heaters themselves, which affected the reliability of the furnace. The use of a nonlinear heating system has changed this distribution to the opposite. The power of the intuboxic heater exceeded the power of the central 1,2‒1,36 times depending on the ratio of the diameters of thin and thick (diameter of 4 mm) of the heaters. At the same time, not only their electrical power increased, but the heat radiation streams, falling onto the surface of the supply, which led to an increase in the temperature of the material being processed. The obtained values of the temperature of the vermiculite grains in the fitted zones of the firing module exceed the temperature of the vermiculite in the central zone by 26 %, while it is sufficient for high-quality material intimidation. Due to the use of nonlinear heating system, temperatures were redistributed on heated surfaces in favor of relatively cold previously intuition zones: the heat picture has changed to the opposite, that is, the cold cloth zones have become relatively hot.

Recenzió a Magyar Dantisztikai Társaság Pokol-kommentárjáról.
Több mint 550 oldalon, keménykötésben foghatja végre kezébe az olvasó Dante Alighieri Isteni színjátékának az első részét kísérő tudományos kommentárt. Bár a szerző idestova hétszáz éve meghalt, élete főművét az azóta eltelt időben folyamatosan értelmezték és újraértelmezték, nemcsak a Commedia poétikai kiválósága, hanem talán az abban rögzített világkép és -rend nyújtotta stabilitás és biztonságérzet vonzósága miatt is. Akár a középkor gondolkodását akarja belőle jobban megérteni az ember, akár a saját világnézetét tenné próbára a dantei tükörben, a Commedia olyan fogódzó, amely még sokáig segítségére lesz az ilyen kérdésekkel küzdő olvasónak. A mű aktualitását jelzi, hogy nemrég Ferenc pápa is újraolvasásra ajánlotta a művet, hogy „tudatosuljon bennünk száműzöttségünk, és hagyjuk, hogy elindítsa bennünk a megtérés folyamatát a rendezetlenségből a bölcsesség, a bűnből az életszentség, a nyomorból a boldogság, a pokol szörnyűségének szemléléséből a paradicsom boldogító megtapasztalása felé.” Persze a második „nagy lemondás” (Pokol, III, 60.) haszonélvezője helyében én sem mondanék rosszat Dantéról és művéről, de ezt majd a kellő időben megbeszélik ők ketten az égi rózsa valamelyik szirmán üldögélve. Ugyancsak a Commedia iránti érdeklődés jele, hogy 2016-ban jelent meg Nádasdy Ádám új magyar fordítása részletes jegyzetapparátussal, magyarázó ábrákkal és táblázatokkal. De akkor mivégre az újabb kiadvány?

Egy impozáns angol nyelvű kézikönyv első fele készült el a cseh humanistákról, amely egy fontos nemzetközi vállalkozás és kutatási program része. A Kiss Farkas Gábor által szerkesztett sorozat elméletileg a magyar humanistákkal indul, de a vonatkozó (számozás szerint első) kötet megjelenését csak 2022-re várja a kiadó. Így került időben előre a cseh szerzőket tárgyaló könyv, amely ábécérendben veszi végig a humanistákat A-tól L-ig. Lucie Storchová szerkesztői bevezetője és a rövidítések jegyzéke után alapos korszaktanulmányokat olvashatunk: Petr Voit „Humanism in the Czech Lands in the First Half of the 16th Century”, Lucie Storchová „Humanist Literature in the Czech Lands (from the 1550s until the Late 1580s)”, Jan Malura – Marta Vaculínová „The Literature of Late Humanism (from the 1590s until the Early 1620s). Ezt követik a szócikkek egységesformátumban: életrajz – művek – kiadások – irodalom. A kötetet végül egy összesített, de válogatott bibliográfia zárja, valamint a személynevek és a földrajzi nevek mutatója.
A kalendárium és használója
Authors: Bódai Dalma
Published: November 2021

Thurzó György naplói a kora újkori napló kialakulásának kezdeti jegyeit viselik magukon. Az 1596-os, 1697-es, 1604-es, 1607-es és 1612-es évekből fennmaradt naplók alapvetően udvari naplóként értelmezhetők, de az utazási naplók és nyomokban a személyes naplók szabályszerűségei is felfedezhetők a szövegeken. A főúr környezetében már a 16. század közepétől meghonosodott naplóvezetési hagyományok, illetve a feleségének írt levelek alapján feltételezhető, hogy a 16. század végétől haláláig, 1616-ig folyamatosan vezetett, illetve írnokai vezettek kalendáriumba írt naplókat. Ezt erősíti meg Thurzó Imre 1617-es évben írt naplója, amely egyértelműen Thurzó György naplóvezetési szokásait viszi tovább, azonban némiképp kiforrottabb módon.

Thurzó György nádor a kalendáriumok nyomtatott naptári részét az idő múlásának számontartására, a bele írt feljegyzéseket pedig a mindennapjai történéseseinek megörökítésére, ily módon mintegy az idővel való elszámolásra használta. Arra vonatkozóan viszont nem maradt fenn utalás, hogy a prognosztikonok szövegeinek és előrejelzéseinek hasznát vette-e, és ha igen milyen módon.

Thurzó György naptárbejegyzéseiben mindennapi életének szubjektív élményei jelennek meg. Az eseményeket az adott pillanatban szemléli, nem reflektált a kor eseményeire, nem következtetett és retrospektív megjegyzéseket sem tett a szövegekbe. A naplók praktikus és nem esztétikai célokat szolgált, elsősorban ez emlékezet segítését, illetve tehermentesítését. Azonban láthatóan ezt sem hosszú távra vonatkoztatva, hiszen a kalendáriumok és bennük a naplók megőrzése láthatóan Thurzó György és fia, Imre számára sem volt fontos. Sokkal inkább rövid távon, pár hónap, esetleg néhány év távlatában őriztek meg általuk visszakereshető módon az udvar mindennapi működésére vonatkozó adatokat.
Агломерации Азербайджана: тенденции демографического и социально-экономического развития
Authors: Этибар Санан оглы Бадалов
Published: November 2021

В статье анализируется историческое развитие и формирование процесса субурбанизации и его влияние на городское расселение Азербайджана. Анализируется динамика роста населения и особенности демографических процессов, а также проблемы социально-экономического развития в городских агломерациях. Так, в постсоветский период произошло увеличение территорий агломераций за счет сельских поселений, получивших статус городского поселка. Происходят функциональные изменения периферии Бакинской и Гянджинской агломераций, где формируются новые промышленные парки, зоны размещения научно-исследовательских организаций и предприятий высоких технологий, а также агропарки и сосредоточения объектов сферы услуг. Автор выявляет трансформации территориальной организации больших и крупных городских агломераций.

Проведен анализ воздействия урбанизации на демографические процессы, в том числе на изменение естественного и миграционного движения населения, половозрастной структуры и брачно-семейного состава населения.

В агломерациях сосредоточено 72,5% всего городского населения республики, и его численность быстро растет. Основным компонентом такого роста является естественный прирост (более 70%), тогда как миграция обеспечивает чуть более 10% прироста. За последние годы произошло неуклонное снижение показателей коэффициентов рождаемости и естественного прироста, снижаются показатели заключения браков и увеличивается количество разводов.

В постсоциалистический период большая часть нестоличных городов бывших социалистических стран испытала стагнацию или сжатие. Однако некоторые из них, напротив, перешли к бурному росту как численности населения, так и застроенной территории. В результате за 30 лет развития в рыночных условиях сформировались протяженные пригородные ареалы. На примере Махачкалы мы рассмотрели внутреннюю структуру этих новых постсоциалистических пригородов. На основе полевых материалов были выделены, типологизированы и сопоставлены между собой функциональные и социальные центры махачкалинской субурбии. Их пространственные структуры частично обусловливают друг друга. Производство социальности в пригородах, в условиях сниженной плотности населения и ослабленности советского городского ядра масштабной эмиграцией, затруднено. Функциональные центры пригородов Махачкалы крайне разнообразны. От осевых центров-линий, продолжающих собственно старый центр города и ориентированных на транзитный поток потребителей, отходят внутрь жилых районов более мелкие центры-линии, функциональное разнообразие которых удовлетворяет локальный спрос. Первичный пионерный тип центра — ядра, состоящие из одиночных магазинов, — доминирует в наименее функционально плотных районах недавней застройки.

В удаленных районах ядро может немного усложняться, тогда возникают комбинации мечетей, магазинов и школ, выступающие местами концентрации социальных практик. Мечети чаще входят в состав ядер в старых районах-селах.

В удаленных районах формируются центры-облака, сосредотачивающие много разнообразных объектов и становящиеся аналогами центральных площадей. Сложных пространственных форм концентрации социальных практик почти не формируется. В основном это одиночные ядра. Распространены как косвенные проявления социального контроля через граффити и плакаты, так и прямые — силами местных неформальных «дружин», в особенности в изолированных этнических пригородах.
