The impact of flow interaction on carbon sequestration potential in an idealised giant kelp forest
Authors: Strong-Wright Jago , Taylor John R
Published: February 2024

Macroalgae re- and afforestation are frequently proposed carbon dioxide
removal (CDR) strategies, but the carbon storage is often uncertain. In
nature, kelp forests grow on hard or sandy substrate leading to as
little as ∼0.4% of their primary production being buried in the kelp’s
habitat (Krause-Jensen and Duarte, 2016) with the remainder exported.
Export of dissolved and particulate carbon from kelp forests is strongly
affected by the exchange of water between the kelp forest and the
surrounding water. The permanence of storage of the exported carbon is
determined by its destination, which is affected by the flow in and
around the forest. Additionally, the potential for forests to grow can
be limited by nutrients dissolved in the water, the availability of
which is determined by the same water exchange rates.

Here, we use OceanBioME to build a numerical model of coupled flow/kelp
interactions to study how tidal currents interact with a giant kelp
(Macrocystis pyrifera) forest. We first validate our model using
observations of currents within and surrounding a kelp forest in
Southern California. By varying the kelp density within our model and
tracking dissolved tracer released from the kelp forest, we analyse the
timescales of water exchange to better understand how the flow
influences carbon export and nutrient uptake. We find a density that
maximizes the export of tracers which coincides with the density typical
of natural kelp forests. Additionally, the drag results in a mean
circulation through the forest and a mean displacement of the
individuals suggesting that the physical dynamics of the kelp should be
an important consideration in future studies and when planning
re/aforestation projects.

Authors: Runowski Henryk
Published: February 2024

W artykule przedstawiono koncepcję zrównoważonego rozwoju rolnictwa i gospodarstw rolnych. Omawiając proces rozwoju gospodarstw rolnych i agrobiznesu, nacisk położono na narastający konflikt pomiędzy ekonomią a ekologią. Oprócz tego określono determinanty zrównoważonego rozwoju gospodarstw rolnych i przedsiębiorstw rolno-spożywczych. Istnieją gospodarstwa ekologiczne i integrowane, które reprezentują praktyki produkcji rolnej najlepiej wpisujące się w zasady zrównoważonego rozwoju. W artykule omówiono rozwój rolnictwa ekologicznego w Europie, w tym w Polsce, a tym samym wskazano główne przeszkody i szanse rozwoju gospodarstw ekologicznych w Polsce. Zdolność do pokonania rozważanych barier w istotny sposób określi możliwości rozwoju gospodarstw ekologicznych w Polsce i ich udziału w praktycznej realizacji koncepcji zrównoważonego rozwoju rolnictwa i obszarów wiejskich.
Kontrakty terminowe w strategiach zabezpieczania się przed niekorzystnymi zmianami cen na Warszawskiej Giełdzie Towarowej
Authors: Kluza Andrzej , Jabłonowski Stanisław
Published: February 2024

W artykule opisano wybrane strategie inwestycyjne kontraktowane na izbach handlowych. Celem tych strategii jest zabezpieczenie inwestora przed niepożądanymi dla niego zmianami cen. Strategie ilustrują dane Warszawskiego Zarządu Głównego Handlowego z lat 1999 i 2000. Wśród licznych możliwych zabezpieczeń przed niepożądanymi zmianami cen towarów, kursów i kursów walut wyróżnia się inwestowanie w kontrakty futures. Kontrakty terminowe rozwijane są w Izbie Giełdowej w Warszawie od początku 1999 roku. Rynek opcji był słaby i od końca 1998 roku zanotował spadek. Prawdopodobnie nie będzie się już bardziej rozwijać. Największe znaczenie mają transakcje terminowe na kursy i kursy walut, gdyż kontrakty terminowe na towary kontraktowane są bardzo rzadko. Opisane wybrane strategie uwzględniają kupno i sprzedaż różnych kontraktów futures oraz kombinacje kontraktów kupna i sprzedaży z kupnem lub sprzedażą instrumentu podstawowego. Strategie zostały przeanalizowane na podstawie danych Biura Handlu m.st. Warszawy.

Dnia 27 października 2000 r. w SGGW odbyła się konferencja Kierunki i możliwości zrównoważonego rozwoju sektora rolno-spożywczego. Organizatorem konferencji był Wydział Ekonomiki Rolnictwa. Dyskusja i prezentacje skupiały się wokół pięciu tematów, a mianowicie: 1. Możliwości i bariery zrównoważonego rozwoju sektora rolno-spożywczego; 2. Tendencje w produkcji rolnej, przetwórstwie, handlu i spożyciu produktów pochodzenia rolnego; 3. Instytucje i narzędzia oddziałujące na gospodarkę żywnościową; 4. Zasoby pracy i ich zatrudnienie w sektorze rolno-spożywczym; 5. Społeczne i tradycyjne aspekty zrównoważonego rozwoju. Konstruktywna debata, szanująca stanowisko wszystkich zainteresowanych, opierała się na artykułach opublikowanych przed konferencją w Zeszytach Naukowych SGGW, Seria Ekonomika i Organizacja Gospodarki Żywnościowej (nr 40 i 41). Konferencja, stanowiąca forum wymiany różnych poglądów, zaowocowała lepszym zrozumieniem problemów zrównoważonego rozwoju w różnych segmentach gospodarki rolno-spożywczej i wysunęła przydatne wnioski dla praktyki biznesowej, społeczeństwa obywatelskiego, środowiska akademickiego i władz publicznych.
Grupy producentów rolnych jako czynnik doskonalenia produkcji i obrotu produktami rolnymi
Authors: Boguta Witold , Siekierski Czesław
Published: February 2024

Wprowadzenie funkcjonującej gospodarki rynkowej, zarówno do polskiego rolnictwa, jak i sektora spożywczego, postawiło przed producentami, przetwórcami i handlowcami rolnymi wiele nowych, niezbadanych jeszcze wyzwań. Postępująca koncentracja popytu, globalizacja gospodarcza, liberalizacja światowego handlu żywnością oraz rosnąca konkurencja wymagają nowych wysiłków i metod działania wszystkich podmiotów gospodarczych w systemie dystrybucji produktów rolno-spożywczych. Zapewnienie podmiotom gospodarczym oczekiwanych wyników finansowych i społecznych wymaga nie tylko dalszego postępu w organizacji rynku sektorowego, ale także istnienia zrównoważonych relacji i współpracy pomiędzy poszczególnymi jego uczestnikami. Grupy producentów rolnych uznawane są za integralną część organizacji rynku rolnego. Bez ich obecności trudno byłoby osiągnąć oczekiwaną poprawę zarówno jakościową i ilościową produkcji rolnej, jak i handlu produktami rolnymi./tłum. lw/
Analiza ekonomiczno-finansowa przedsiębiorstw hodowli roślin ogrodniczych w latach 1997-1999
Authors: Filipiak Tadeusz
Published: February 2024

W artykule przedstawiono analizę ekonomiczno-finansową przedsiębiorstw hodowli ogrodniczej będących własnością Agencji Państwowej Własności Rolnej. Firmy te mają ogromne znaczenie w rozwoju postępu biologicznego, gdyż są właścicielami 65% polskich podgatunków warzyw znajdujących się w Urzędowym Rejestrze Podgatunków. W okresie objętym badaniem sytuacja tych przedsiębiorstw była bardzo trudna, ale wewnętrznie odmienna. Pomimo tej sytuacji można było zaobserwować pozytywne zjawiska, takie jak np. lepsze wykorzystanie majątku trwałego i obrotowego, zwiększenie efektywności pracy oraz poprawę rentowności. Spółki charakteryzujące się wysoką rentownością majątku charakteryzowały się lepszą rentownością sprzedaży w porównaniu do spółek charakteryzujących się niską rentownością majątku. Dodatkowo, w konsekwencji pierwszych osiągnięć, lepsze wyniki ekonomiczne, zarówno w działalności operacyjnej, jak i ekonomicznej.lw

Objectives: Parkinson’s disease is characterized by motor and non-motor symptoms. Tremor is one of the motor symptoms that can affect manual skills and have an impact on daily activities. The aim of the current study is to investigate the effect of upper limb training provided by a specific vibratory device (Armshake®, Move It GmbH - Bochum, Germany) on tremor and motor functionality in patients with Parkinson’s disease. Furthermore, the training effect on global cognitive functioning is assessed.
Design: An uncontrolled before-after clinical trial.
Patients: Individuals with diagnosis of Parkinson’s disease, motor upper limbs deficits, and absence of dementia.
Methods: Participants underwent a 3-week programme (3 times a week) and was evaluated before, after, and at 1 month follow-up by motor (Fahn Tolosa Marin Tremor Rating Scale, Unified Parkinson’s Disease Rating Scale – part III, Purdue Pegboard Test, Disability of the Arm, Shoulder and Hand Questionnaire) and cognitive (Montreal Cognitive Assessment) scales.
Results: Twenty subjects are included. After treatment a statistically significant improvement in tremor, manual dexterity and activities of daily living was found. The data indicated no effects on global cognitive functioning.
Conclusion: These findings suggest positive effects of vibratory stimulation training on upper limb motor symptoms in Parkinson’s disease.
Physicochemical and In-Vitro Bioequivalence Analysis of Some Oral Solid-Dosage Metronidazole Formulations
Authors: SJ Bunu
Published: February 2024

Background: Metronidazole is a 5-nitroimidazole antimicrobial agent, widely used in the treatment of infections caused by Trichomonas vaginalis, such as trichomoniasis, pseudomembranous colitis, and symptomatic amoebiasis resulting from anaerobic bacteria. Aim: The study aimed to qualitatively determine the quality and in-vitrobioequivalence of selected brands of metronidazole tablet dosage forms used in the management of infectious diseases. Method: The British Pharmacopeia (BP) Standard methods were followed to conduct weight uniformity, disintegration time, hardness, and friability tests. For the Thin Layer Chromatographic (TLC) Fingerprinting, 0.1g of the brands were weighed and dissolved ins 50 ml methanol (50%). The stock solution was prepared using 50% methanol and 50% dichloromethane and was transferred into the Chamber and allowed to stand for about 45 minutes; the plates were viewed under UV-VIS Spectrophotometer at 365 nm. Result: All the brands complied with the acceptable friability limit, and disintegrated within the appropriate time of not more than 15 minutes as specified in BP, for uncoated tablets. The tablets were found to have a dissolution profile of at least 70% of the active ingredient taken at 45 minutes from the dissolution medium as stated in BP. The analysis showed the consistency of concentration of the selected tablet brands with the label claims. Conclusion: The TLC procedure used in the analysis was accurate and precise, no interference was observed from the excipients. Thus, this method can be used in the routine quality control of metronidazole solid dosage form.

Authors: Latas Joana , Soares Hugo
Published: February 2024

Resumo
A par da publicação científica e da divulgação nos meios de comunicação social inerente à expedição para observação do eclipse solar de 29 de maio de 1919, a presença de uma equipa liderada pelo astrónomo britânico Arthur Eddington na ilha do Príncipe a este propósito, e em particular a sua estada na roça Sundy, foi documentada pelo próprio em cartas dirigidas à mãe e à irmã. O que viu Eddington na ilha do Príncipe?  Este é o mote para a conceptualização de um Trilho de Ciência que convida, ao longo do seu percurso, o participante a interagir com diferentes dimensões do conhecimento e da realidade local por meio de experiências integradoras que envolvem arquitetura, astronomia, física, história e matemática com o intuito de conjugar, de forma harmoniosa e equilibrada história e ciência; património e futuro; desenvolvimento e preservação. O formato deste Trilho de Ciência, tendo como ponto de partida outros já existentes na ilha do Príncipe, está a seguir a metodologia resultante da investigação e das atividades de divulgação do projeto E3 Global (https://e3global.pt/) que tem por principal objetivo escrever a primeira história global do eclipse de 1919.

Biografia Científica de João Manso Pereira e a contribuição africana e afro-brasileira para o desenvolvimento da Química no Brasil
Authors: Lira Priscila , Paredes Antunes Ettore
Published: February 2024

Em 2023 completou-se 20 anos desde a aprovação da lei nº 10.639/2003 que estabelece a obrigatoriedade do ensino de história e cultura africana e afro-brasileira na educação brasileira, visando o desenvolvimento de uma educação que favoreça o respeito e a valorização das diferenças étnico-raciais e o combate ao racismo. Infelizmente, a implementação desta lei nas escolas e universidade ainda é pequena e superficial, um dos principais problemas relados na literatura é um ensino eurocentrado, a falta de materiais didáticos, ausência da temática no curso de formação de professores, principalmente no ensino de Ciências e Química. Por isso, o presente estudo tem como objetivo apresentar a biografia científica sobre o químico negro João Manso Pereira, que contribua para abordagem da história e cultura africana e afro-brasileira articulada com a história da Química no Brasil, destacando o trabalho realizado por João Manso no período colonial nas mais diferentes atividades científicas e tecnológicas desenvolvidas na mineração; a destilação da aguardente; a produção das nitreiras e sua participação na Academia Cientifica do Rio de Janeiro. A construção da biográfica se baseia na Historiografia Crítica da Ciência que faz uma análise histórica do particular, singular e universal, possibilitando uma abordagem da história da ciência contextual, que valorize aspectos internos e externos da ciência, estimule a criticidade e o possibilite um ensino de ciências antirracista.

O Percurso Histórico da Ciência como Proposta de Conteúdo para o Letramento Científico
Authors: Zanatta Shalimar Calegari , Royer Marcia Regina , Maqueira Alexandre Gabriel , Alves Pereira de Carvalho Hercilia
Published: February 2024

Resumo
O presente artigo objetiva mostrar, por meio de discussões argumentativas e fundamentadas na Epistemologia de Gaston Bachelard, como a História da Ciência (HC) pode auxiliar no processo de formação do aluno visando o letramento científico (LC), como definido pela Base Nacional Comum Curricular (BNCC). Este documento, norteador da educação brasileira, define LC como a capacidade do indivíduo em fazer escolhas, emitir opiniões de forma consciente com base no conhecimento científico e na compreensão dos fenômenos, exercendo assim, sua plena cidadania. Porém, a BNCC não explicita os conteúdos que devem ser abordados pelo professor. O referido documento traz as competências e habilidades que devem ser desenvolvidas no aluno, tornando assim a escolha dos conteúdos, um grande desafio. Por outro lado, no Brasil, as políticas púbicas educacionais, têm estado a serviço das políticas neoliberais, as quais, valorizam os conteúdos do cotidiano do aluno. Assim, como resultado, mostramos que os conteúdos sobre a HC podem promover o LC, como definido pela BNCC e isto está relacionado ao combate às Fakes News.

Abstract
This article aims to show, through argumentative discussions based on Gaston Bachelard's Epistemology, how the History of Science (HC) can help in the student training process aiming at Scientific Literacy (LC), as defined by the National Common Curricular Base (BNCC). This document, guiding Brazilian education, defines LC as the individual's ability to make choices, express opinions consciously based on scientific knowledge and understanding of phenomena, thus exercising their full citizenship. However, the BNCC does not explain the contents that must be worked by the teacher. This document contains the skills and abilities that must be developed in the student, making the choice of content a great challenge. On the other hand, in Brazil, public educational policies have been at the service of neoliberal policies, which value the content of the student's daily life. Thus, as a result, we show that content about HC can promote LC, as defined by BNCC and this is related to combating Fake News.

O trabalho prático no ensino das ciências: Uma abordagem à evolução histórica
Authors: Bonito Jorge , Oliveira Hugo
Published: February 2024

O trabalho prático é atualmente considerado, por muitos investigadores e educadores, como uma componente estruturante da educação em ciências. Este trabalho pretende fazer uma sinopse histórica do trabalho prático no ensino das ciências. Depois de uma breve passagem pela antiguidade até ao séc. XIX, prossegue com uma visão do contexto português, destacando importantes episódios que influenciaram o ensino prático e experimental neste campo do conhecimento. Seguidamente, analisam-se as visões sobre o trabalho prático, nas mais recentes alterações curriculares no sistema de ensino português, representadas pelas Metas Curriculares e pelas Aprendizagens Essenciais em articulação com o Perfil dos Alunos à Saída da Escolaridade Obrigatória. Conclui-se que, a concetualização e a relevância do trabalho prático foram alterando num processo dinâmico ao longo do tempo, acompanhando os diferentes paradigmas económicos, políticos e sociais que se foram sucedendo, aproximando-se ainda alternadamente, de abordagens mais influenciadas por um estilo minds-on, e de abordagens mais influenciadas por um estilo hands-on. Por último, considera-se como premente o debate sobre a atual relevância do trabalho prático, com vista à sua otimização e ao estabelecimento do seu futuro formato, no ensino das ciências do sistema educativo português, no quadro dos atuais referenciais curriculares.

Resumo
Esta pesquisa objetiva abordar diferentes períodos históricos através de recorte temático da história da educação brasileira, passando pelo Brasil Colônia até o século XX, na intuição de elucidar como as pesquisas em ensino de Ciências se consolidaram no país. Para isso, realizou-se análise documental e legal e pesquisa bibliográfica. As evidências mostram que a busca e desenvolvimento das pesquisas em ensino de Ciências no Brasil ganharam força a partir do desenvolvimento das tecnologias introduzidas em outros países no final da década de 50. O século XX trouxe profundas mudanças na sociedade brasileira e estas mudanças influenciaram a educação. Em 1996, sob a Lei n. 9.394, entra em vigor, as diretrizes e bases para a educação nacional. O educando passa a ser educado para o trabalho e a cidadania, ficando de lado a formação científica. Porém, com as mudanças vigentes no país e a globalização, o currículo de Ciências também sofreu alterações para atualização de temas, como por exemplo, conteúdos sobre o clima no planeta, as crises energéticas e os processos mundial do meio ambiente. Neste contexto, as pesquisas em ensino Ciências foram muito dependentes das circunstâncias, desenvolvidas principalmente em momento de crises e agravamento social e, isto interferindo na formação docente para que os problemas fossem resolvidos por estes profissionais.

Abstract
This research aims to address different historical periods through a thematic section of the history of Brazilian education, passing through colonial Brazil until the 20th century, with the intention of elucidating how research in Science teaching was consolidated in the country. For this, documentary and legal analysis and bibliographic research were carried out. Evidence shows that the search and development of research in Science teaching in Brazil gained strength from the development of technologies introduced in other countries at the end of the 1950s. The 20th century brought profound changes in Brazilian society and these changes influenced education. In 1996, under Law no. 9,394, the guidelines and bases for national education come into force. The student becomes educated for work and citizenship, leaving aside scientific training. However, with the changes in force in the country and globalization, the Science curriculum also underwent changes to update topics, such as content on the planet's climate, energy crises and global environmental processes. In this context, research in Science teaching was very dependent on circumstances, developed mainly in times of crisis and social worsening, and this interfered with teacher training so that problems could be solved by these professionals.

Reinier De Graaf e a Biologia Reprodutiva
Authors: Calado Ana Margarida
Published: February 2024

Resumo
O cientista holandês do século XVII Reinier De Graaf (1641-1673) é considerado o fundador da biologia reprodutiva moderna. O seu nome está associado ao corpo lúteo, às trompas de Falópio e aos folículos ováricos. A monografia de De Graaf sobre o sistema reprodutor masculino foi publicada em 1668. Cerca de quatro anos depois, em 1672, foi publicado seu trabalho sobre o trato genital feminino, que continha a famosa descrição dos folículos ováricos. De Graaf descreveu em detalhe estruturas associadas aos aparelhos genitais masculinas e femininas, incluindo ductos eferentes, corpos lúteos, trompas de Falópio e especialmente o folículo ovárico. De Graaf teve a clareza de perceber que a trompa de Falópio era responsável pelo transporte do gâmeta ovulado e documentou com sucesso que as gestações ectópicas ocorrem no interior desta estrutura. Mas o legado de De Graaf reside no folículo ovário pré-ovulatório. De Graaf visualizou a ovulação e descreveu esse processo de forma eficaz, numa época em que o microscópio ainda estava a ser desenvolvido. Neste trabalho iremos descrever as descobertas, observações e avaliações críticas de Reinier De Graaf que contribuíram para a compreensão da procriação humana.

Abstract
The 17th-century Dutch scientist Reinier De Graaf (1641-1673) is considered the founder of modern reproductive biology. Its name is associated with the corpus luteum, the fallopian tubes and the ovarian follicles. De Graaf's monograph on the male reproductive system was published in 1668. About four years later, in 1672, his work on the female genital tract was published, which contained the famous description of the ovarian follicles. De Graaf described in detail structures associated with the male and female genitalia, including the efferent ducts, corpora lutea, fallopian tubes and especially the ovarian follicle. De Graaf had the clarity to realize that the fallopian tube was responsible for transporting the ovulated gamete and he successfully documented that ectopic pregnancies occur within this structure. But De Graaf's legacy lies in the preovulatory ovarian follicle. De Graaf visualized ovulation and described this process effectively, at a time when the microscope was still being developed. In this work we will describe Reinier De Graaf's discoveries, observations and critical evaluations that contributed to the understanding of human procreation.

Published: February 2024

Resumo
Existem lacunas sobre a atuação e a formação da enfermeira na realidade cearense, o que torna frágil o conhecimento histórico acerca dessa categoria profissional. Objetiva-se, assim, reconstituir as raízes da atuação e formação em Enfermagem no Ceará, no período de 1865 a 1943, com vistas a contribuir com os conhecimentos no campo de formação, ensino e história dessa profissão. Trata-se de estudo histórico do tipo documental, tendo como campo empírico o estado do Ceará. Como fonte documental, reporta-se para as matérias jornalísticas. Pode-se identificar que o profissional de Enfermagem se destaca a partir da criação dos hospitais e a formação desse trabalhador, que ocorria apenas a partir da observação de como se dava assistência hospitalar, se modifica com as exigências do mercado. Isso porque, à medida que esse trabalhador da saúde foi-se tornando mais necessário, houve a preocupação em ofertar cursos de formação, inclusive no próprio estado, a fim de valorizar o próprio contexto cearense e, por conseguinte, suas demandas. Constata-se, portanto, que as matérias jornalísticas se configuram como estratégia para reconstituir a história da Enfermagem, em relação à profissão e formação, trazendo, assim, à tona outras percepções, ainda pouco exploradas, acerca do tema em estudo.

Abstract
There are gaps in the role and training of nurses in Ceará, which makes historical knowledge about this professional category fragile. Thus, the objective is to reconstitute the roots of Nursing activities and training in Ceará, from 1865 to 1943, with a view to contributing to knowledge in the field of training, teaching and history of this profession. This is a documentary-type historical study, having the state of Ceará as an empirical field. As a documentary source, it reports to journalistic articles. It can be identified that the Nursing professional stands out after the creation of hospitals and the training of this worker, which occurred only from the observation of how hospital care was provided, changes with the demands of the market. This is because, as this health worker became more necessary, there was a concern to offer training courses, including in the state itself, in order to value the Ceará context itself and, consequently, its demands. It appears, therefore, that journalistic articles are configured as a strategy to reconstruct the history of Nursing, in relation to the profession and training, thus bringing to light other perceptions, still little explored, about the topic under study.

O Predomínio das Histórias da Ciência Internalistas e a Permanência da Ausência de Historiadores Brasileiros na Escrita da Ciência e Seus Reflexos no Ensino de História
Authors: Almeida Douglas Cesar de
Published: February 2024

Resumo
O artigo discute sobre a total ausência da História da Ciência na pesquisa em ensino de história no Brasil. Inicialmente apresentamos a emergência do campo da História da Ciência em dois contextos distintos. No primeiro contexto, a História da Ciência emerge como subcampo de estudos das ciências particulares, com enfoque na história das ideias. No segundo contexto, a História da Ciência nasce como subcampo de saber historiográfico a partir da Revolução Documental representada pela Nova História, com foco na história social das ciências. Essas duas vertentes, que possuem como objeto a História da Ciência, coexistem de forma relativamente autônomas e independentes. Assim, as diversas gerações de historiadores e de historiadores da ciência, têm contribuído para o desenvolvimento do conhecimento científico da área, e alargando o campo para as reflexões sobre o ensino de História da Ciência. Por um lado, temos a contribuição da História da Ciência produzida pelas diversas ciências particulares na prática pedagógica, em especial as metodologias CTSA e STEAM. E por outro, a permanência da ausência da História da Ciência como objeto de estudo historiográfico, com seus reflexos no ensino de História. Dessa forma, defendemos a necessidade da História em se apropriar e contribuir no campo de pesquisa da História da Ciência, e por extensão do seu ensino na sala de aula de História.

Abstract
The article discusses the total absence of the History of Science in research on history teaching in Brazil. Initially, we present the emergence of the field of History of Science in two different contexts. In the first context, the History of Science emerges as a subfield of particular science studies, focusing on the history of ideas. In the second context, the History of Science is born as a subfield of historiographical knowledge from the Documental Revolution represented by the New History, focusing on the social history of the sciences. These two strands, which have the History of Science as their object, coexist in a relatively autonomous and independent way. Thus, the different generations of historians and science historians have contributed to the development of scientific knowledge in the area, and widening the field for reflections on the teaching of the History of Science. On the one hand, we have the contribution of the History of Science produced by the various particular sciences in pedagogical practice, in particular the STSE and STEAM methodologies. And on the other hand, the permanence of the absence of the History of Science as an object of historiographical study, with its reflections on the teaching of History. In this way, we defend the need for History to appropriate the research field of the History of Science, and by extension its teaching in the History classroom.

ОЦЕНКА КАЧЕСТВА И УСЛОВИЙ РАЗВИТИЯ ЧЕЛОВЕЧЕСКОГО ПОТЕНЦИАЛА МОЛОДЕЖИ ХАБАРОВСКОГО КРАЯ И ДАЛЬНЕВОСТОЧНОГО ФЕДЕРАЛЬНОГО ОКРУГА (В АСПЕКТЕ ОДАРЕННОСТИ)
Authors: Кузнецова Алла , Борзова Татьяна
Published: February 2024

В докладе представлены результаты исследования состояния качества человеческого потенциала детей и молодежи (возрастной группы 7-35 лет) Хабаровского края и Дальневосточного федерального округа в аспекте одаренности и высоких достижений как основы для выстраивания региональных стратегий в области социально-экономического развития, образовательной, социальной и иных политик.

Разработаны теоретические основания исследования и оценки человеческого потенциала не только в аспекте демографических, социальных и экономических характеристик, отражающих в большей степени возможности и условия человеческого развития, но и в аспекте реализации потенциала - высоких достижений как проявления одаренности, на которую и стоит делать ставку в реализации амбициозных программ опережающего развития региона.

Обоснована необходимость оценки человеческого потенциала молодежи как наиболее активной социально-демографической группы, которой и предстоит быть реализатором и двигателем будущих преобразований.

Показана возможность применения относительных статистических показателей (интенсивных коэффициентов) для выявления тенденций развития человеческого потенциала молодежи региона в аспекте высоких достижений.

На основе сравнительного анализа данных об уровне образования, об образовательных достижениях обучающихся, качестве образования, о развитии демографических процессов на Дальнем Востоке и в других территориях России сделаны предположения о причинах формирования негативных тенденций и сравнительно более низких характеристик общего человеческого потенциала региона и человеческого потенциала молодежи в аспекте одаренности (высоких достижений).
La trayectoria del pensamiento de Héctor Aguilar Camín a través de sus polémicas
Authors:   , Arellano Mendoza Jorge Luis
Published: February 2024

Sobre la trayectoria del pensamiento de Héctor Aguilar Camín, a través de sus polémicas, respecto a tres temas particulares: el intelectual y su relación con el Estado; el ideario (¿neo?)liberal y el tránsito a la democracia en el país (su pensamiento político) y la utilidad de la historia y el tipo de historia que se genera desde el Estado (su pensamiento histórico), es que se dedica el presente estudio. Lo primero que hice fue seleccionar las polémicas y al agruparlas pude percatarme que a pesar de la diferencia de tiempos en que ocurrieron había en ellas persistencia en algunos temas por lo que eso facilitó el capitulado de la tesis. Creo no exagerar al afirmar que el contenido de esas polémicas fueron las que orientaron y al mismo tiempo problematizaron el presente trabajo. Cronológicamente, y sin entrar en detalles por el momento, se pueden agrupar en tres grandes periodos las polémicas de Héctor Aguilar Camín (HAC): juventud (décadas de los 70 y 80), madurez (década de los 90) y vejez (años de la transición y la administración de AMLO). Esta última decidí incluirla a pesar de su cercanía porque, a mi parecer, es vital para reconocer de mejor manera esas transformaciones en su pensamiento. Por último, cabe mencionar que a pesar de ser una tesis quise, y espero haberlo logrado, que cada capítulo pudiera leerse por separado, para cualquier interesado en los temas particulares que se trata en cada uno de ellos.
Resveratrol and curcumin against diabetic retinopathy. Better together than apart
Authors: Kabiesz Adam
Published: February 2024

The health-promoting effects of curcumin and resveratrol have been known for a long time. The most important features of polyphenols include their effect on blood vessels and participation in the neutralization of free oxygen radicals. Both resveratrol and curcumin exhibit antioxidant effects, and the combined use of both substances significantly improves their effectiveness. In the fight against diabetic retinopathy, the antiangiogenic effect of polyphenols also turn out to be important. Many researchers also point to the possibility of using resveratrol and curcumin in cancer therapy.
Using Social Influence Technique as a Tool to Reduce the Diffusion of Responsibility on the Internet

Diffusion of responsibility is a well-known effect widely studied in a real-life setting. It can occur in a situation in which the more people observe a crisis event, the less likely it is that someone will react and provide real assistance. These days of a galloping digital revolution a question is to be raised as to whether the same effect can be observed in the online space of communication. In order to investigate this phenomenon we designed a study aimed at testing whether people exposed to a situation of cyberbullying will decide to take action against it depending on how many other Internet users are also aware of that crisis. Results obtained by us confirmed the existence of the diffusion of responsibility in the Internet similar to that observed in our daily lives. We also confirmed that a well-known influence technique “Even a penny will help” (in our study “every reaction will help”) can be effectively used to model behaviour online. In our times of digital revolution, those outcomes can be a step both toward understanding human behaviour in the online setting, showing us that it is not that different from the one presented in real live face-to-face communication and toward helping deal with antisocial behaviour people face online on a daily basis.
Predictors of environmental guilt, and its role as a mediator of the association between human-nature relation and pro-environmental behavior intentions

The aim of the two studies (N = 245 and N = 199) was to investigate the predictors of environmental guilt and analyze its mediating role between human-nature relationship and pro-environmental behavior intentions. In the first study, the connectedness to nature and social dominance orientation emerged as predictors of environmental guilt. In addition, guilt was an important mediator of the relationship between the connectedness and individual pro- environmental behavior. In the second study, guilt was predicted by gender, by locating the causes of the climate crisis in human activities rather than in the Earth's natural cycles, and by environmental nostalgia. In addition, guilt mediated the relationship between environmental nostalgia and willingness to engage in collective action and support systemic changes. Thus, environmental guilt seems to be an important factor in predicting a wide range of environmentally friendly activities: individual behavioral intentions, willingness to engage in collective actions, and support for systemic changes.
Social assistance or agency? Attachment Styles Moderate the Impact of Control Threat on Social Relationship Preferences
Authors: Gasiorowska Agata , Zaleskiewicz Tomasz
Published: February 2024

Building upon Gasiorowska and Zaleskiewicz's (2021, 2023), we explored how a control threat and attachment style influence social relationship preferences. This experiment aimed to investigate how experiencing a control threat affects individuals with secure, anxious, and avoidant attachment patterns when they can choose between seeking assistance from the market, asking a close person for help, or coping with the situation alone. Participants with different attachment styles were randomly assigned to either the lack of control condition ( n = 290) or the having control condition ( n = 277). Individuals with an anxious attachment were more inclined to choose the market-exchange option and less likely to select the agentic and communal options when faced with a control threat. Meanwhile, those with an avoidant attachment exhibited a higher tendency to choose the agentic option, while their preference for noncontingent help decreased after exposure to the control threat. Surprisingly, secure attachment individuals showed an increased preference for noncontingent help and decreased preferences for market exchange and self-reliance when exposed to the control threat compared to when they had control. These findings suggest that participation in market relationships may meet vital psychological needs and serve as a safeguard against attachment insecurities.
EU Defence Policy: Between Functionalism, National Interests, and Transatlantic Realities
Authors: Kuokštytė Ringailė
Published: February 2024

Existing insights into recent defence integration, including against the backdrop of Russia’s war, largely stem from EU governance studies. Although these studies might not explicitly delve into the EU’s politico-strategic role, when combined with the broader framework of International Relations (IR), they imply the EU’s effective progression, at least relatively, as a defence actor. However, a closer analysis of certain key developments and transatlantic dynamics suggests a persistent lack in the political and strategic dimensions of EU defence policy. This disparity arises when IR concepts are tailored to fit the EU context in integration studies.
The Situation of Young People’s Political Participation in Albania

Published: February 2024

The right to participate in political life – especially for youth – is very important for an inclusive society. Although the population under the age of 30 represents about 40% of the total population in Albania, the participation of young people in the political, social, and economic spheres remains low. Under current conditions, the youth in Albania tend to remain uninvolved in policy-making, and thus unable to influence their social and economic status. This article points analyzes the economic, social, and political situation of Albanian youth with some recommendations for policy makers related to each area. The institutional and legal structures for young people and the participation of young people in politics are not well developed in Albania. There is a need to review and strengthen the country’s institutional/legal framework at all levels, in order to make young people a more important factor in the society.
A Decision Support Model for Mitigating Supply Chain Risks Based on a Modified FMEA, Multi-Objective Optimization and Multi-Criteria Decision-Making Approach
Authors: Kayouh Nabil , Dkhissi Btissam
Published: February 2024

Recent years have seen a huge development in the subject of supply chain risk management. In this increasingly uncertain world, the use of practical and effective tools for decision making and risk mitigation has become more necessary than ever. In this research, mitigation strategies for a tier one multinational company operating in the automotive industry and providing an assembly operation to final customer Renault Tanger and Renault SOMACA were prioritized according to their effectiveness, as well as their implementation costs. Based on research in the literature and the opinions of experts in the field. 44 risks and 55 mitigation strategies were identified. FMEA (Failure Modes and Effects Analysis) method was used based on the latest AIAG 2019 edition to filter and identify the risks to be prioritized, we used then a multi-objective optimization approach to identify the mitigation strategies that constitute the Pareto front for each of the risks and finally used the EDAS method for the final ranking of the strategies. Our case revealed that strategies like ensuring elaborating a contingency planning and defining the responsibilities, imposing contractual obligations on subcontractors, applying a flexible supply contract were found to be relevant risk mitigation strategies for the company. Managers interested in mitigating risk can deploy this model to prioritize risk mitigation strategies.

Background:

Renal arteriovenous fistula (RAVF) is a serious complication that may occur within the first few days following percutaneous nephrolithotomy (PCNL) procedures. It is usually an iatrogenic complication.

Case Presentation:

We are presenting a case in which a patient had pseudoaneurysm following PCNL and was treated endovascularly, followed by a sudden RAVF 25 days after the pseudoaneurysm treatment, which was treated once again endovascularly.

Conclusion:

Although RAVF was not seen in the early stage during the Digital subtraction angiography that was performed during the treatment of pseudoaneurysm, it suddenly symptomatically appeared in the late stage. We should keep hemorrhagic complications in mind during later stages.
