Published: December 2022

This study aims to describe the development of Student Worksheet materials teaching the Project Based Learning approach at MTs An-Nashuha Kalimukti Pabedilan-Cirebon Regency in mathematics learning on opportunity material. Mathematics learning is done by applying the project-based learning approach with a sample class of 35 students. The method used is the cluster random sampling technique, which takes clusters or groups, not based on population members taken one by one or individually. The use of data is a test instrument in the form of a pretest and posttest to measure the value of student results of learning outcomes and a questionnaire to determine student responses to the use of worksheets with the Project Based Learning approach. The pretest and posttest tests show that students have increased, Normal and homogeneous distribution. Furthermore, to determine the effectiveness of teaching materials, researchers used the Paired Sample t-Test. The Paired Sample t-Test calculation results showed a significance value of 0,000. Thus the significance value is smaller than 0.05, and 10.280 is more incredible than t table 2.04. Based on the results of the calculation of tcount> t-table, Ho is rejected. Because there are, there are differences in the average initial and final scores on the subject matter of opportunities and the use of Student Worksheet teaching materials as the development of materials teaching products are considered quite effective.
ICT and Learning of Mathematics in Nigeria
Authors: Umar Abdullahi  , Musa Sirajo
Published: December 2022

This study empirically reviews ICT and mathematics learning in Nigeria through a systematic literature review. Relevant articles and journals were identified to examine international students' teaching and learning experiences. Research shows that even if teachers believe that students need to understand mathematics or that the use of ICT improves students' development, students still need to solve problems. It may indicate that They do not incorporate her ICT into math classes or use it in traditional ways to impart knowledge. Her effective use of ICT in mathematics education may lead to more learner-centered classroom practices. These changes are widely believed to impact mathematics teaching and to learn positively. For example, ICT can enrich students' mathematics learning experience, increase their interest in mathematics, and change their attitudes toward mathematics. With the proliferation of online e-teaching, flipped classrooms are becoming a new trend in digital learning. The study recommends that ICT tools be made available by all parties to teachers and students with appropriate Internet access to achieve solid academic performance in mathematics. Governments at all levels need to increase their budgets for education and ensure that the money allocated for education is entirely spent.

Published: December 2022

Background: Inaccurate test results may be a reason why vitamin D deficiency is seen as a common problem worldwide. Interferences from the sample matrix during testing are the most important factors in measurement errors. In this study, the relationship between triglycerides and total cholesterol levels and vitamin D levels in Turkey was investigated. Methods: The 25-hydroxyvitamin D test results and lipid test results studied in Turkey in 2021 were compared. Data were obtained from the Ministry of Health National Health Database. Simultaneously, 25-hydroxyvitamin D, triglyceride, and total cholesterol levels were studied, and 1,135,644 test results were taken as the basis. Results: In the group of patients with total cholesterol levels between 0-10.33 mmol/L, the proportion of patients below 20 mg/L ranged from 56.8% to 61.8%. In the patient group with cholesterol between 10.36-259 mmol/L, the rate of patients with less than 20 mg/L was between 70.8-100%, while the rate of patients with cholesterol above 100 mg/L was 0%. The mean 25-hydroxyvitamin D level was 20.1 mg/L in the patient group with a total cholesterol level between 0-10.33 mmol/L, and 16 mg/L in the patient group with a cholesterol level above 10.36 mmol/L. The mean 25-hydroxyvitamin D level was 20.11 mg/L in the patient group with triglycerides 0-10.16 mmol/L, and the 25-hydroxyvitamin D level was 12.28 mg/L in the patient group with triglycerides 10.17-113 mmol/L. The proportion of patients with vitamin D levels above 100 mg/L was found to be 0% in the group of patients with triglycerides above 10.17-113 mmol/L. Conclusions: According to this study, there is a risk of toxicity when administering vitamin D therapy in patients with high cholesterol and triglycerides levels. This study is the first of this size in the literature. High triglycerides and cholesterol levels can cause inaccurate measurement of vitamin D levels, so care should be taken when evaluating these tests.

Published: December 2022

Introduction: Patients with refractory chronic spontaneous urticaria (CSU) may pose a significant challenge to the treating physician. Although many studies have investigated the effects of omalizumab in refractory CSU, many issues remain unanswered. Aim: To describe our experience in treating refractory CSU with omalizumab in a real-life setting. Material and methods: We present a series of eight patients with refractory CSU treated with omalizumab during a 2-year period. Results: The average duration of CSU was 49.9 months (3-180). A high average 7-day Urticaria Activity Score (UAS7) of 31.3 (12-42) and a low average Urticaria Control Test (UCT) score of 4.1 (0-8) had been recorded before omalizumab therapy. Prior to omalizumab, all patients required fourfold dose of H1-anihistamines, montelukast and corticosteroids to achieve at least a partial disease control. Antimalarial was given to two patients and dapsone to three, with no response. Adverse effects of corticosteroids were noted in most patients. Patients received 150 mg or 300mg of omalizumab subcutaneously every 4 weeks, for at least 3 months. All patients responded well to omalizumab and discontinued corticosteroid therapy. There were no significant side effects during omalizumab treatment. Conclusion: Omalizumab is an effective corticosteroid sparing treatment, enabling disease control in patients with refractory CSU, even in lower doses (150 mg) and when given for a short period of time. This is especially important when the availability of the drug is determined by economic issues.
Supervisor education and quality of PhD studies: Current status and future challenges
Authors: Milovanović Petar , Pekmezović Tatjana
Published: December 2022

Supervision is a specific relationship, where an experienced senior researcher provides guidance, support, and advice to navigate a junior colleague through the barriers to becoming an independent researcher. While supervision is clearly a rewarding duty, it is also associated with a number of challenges. It is clear that supervision involves many responsibilities, which means that the supervisor needs to possess a certain set of skills. While many of these skills are learned in the direct interaction with PhD candidates, it would be beneficial if a more formal and structured training was offered to supervisors, especially at the beginning of their supervision careers, so as to avoid frequent mistakes in the supervisor-PhD candidate relationship. Hence, the idea is to shift from experience-based supervision to professionalization, believing that such an approach would reduce the risk of poor supervision. At present, many universities offer formal education of supervisors. The practice of organized education of supervisors at University of Belgrade Faculty of Medicine started in 2019 with the aim of preparing future supervisors to establish productive and responsive relationships with PhD candidates. After a break due to the COVID-19 pandemic, a revised supervision course was organized in 2022. The survey conducted among the attendees of the two organized courses supported the need for better education of university teachers in terms of supervision skills and leading of PhD candidates. Indeed, considering the fact that PhD outcomes are largely dependent on the supervisor and the successful supervisor-PhD candidate relationship, supporting supervision through formal training and education may be an important step in improving PhD experience and outcomes for both supervisors and PhD candidates.
Application of fractal and textural analysis in medical physiology, pathophysiology and pathology
Authors: Pantić Igor , Paunović-Pantić Jovana , Radojević-Škodrić Sanja
Published: December 2022

Fractal and textural analyses represent a rapidly developing class of computational and mathematical methods with potential wide applications in medicine and biology. In recent years, they have been successfully used for the evaluation of subtle alterations in cell and tissue morphology associated with various physiological and pathological processes. It has been shown that cells in early stages of apoptosis exhibit changes in chromatin fractal and textural features. Cellular senescence is also sometimes associated with changes in textural patterns in some cell populations. So far, artificial intelligence approaches based on co-occurrence matrix textural data were successfully implemented in predicting cell damage in in vitro conditions, with artificial neural networks achieving the best performance. In the future, several methodological issues and challenges related to the use of fractal and textural methods will have to be resolved before their introduction into contemporary clinical practice. This concise review focuses on the recent research on the application of fractal and textural methods in experimental physiology and related fields.

Authors: Šljivić Miroslav
Published: December 2022

This paper deals with the relationship between two politicians in the period from 1935, when parliamentary elections were held in the Kingdom of Yugoslavia, to the beginning of the Second World War in the country, in 1941. Based on the materials from the archives and memoirs, the paper traces the role of Dragoljub Jovanović, a politician and a university professor, as a mediator between the opposition in Serbia and Vlatko Maček, the leader of Croatian Peasant Party after the death of Radić, in the period before, during and after the parliamentary elections in 1935. and 1938. There were ups and downs in the relationship between the two politicians, especially after the formation of Banovina Hrvatska at the end of August, 1939. The beginning of the Second World War in Yugoslavia took them to different sides which cut off their contact.
Social mobility in Britain and Serbia: Surveys and findings
Authors: Antonić Slobodan
Published: December 2022

The first part of the article provides an overview of British studies of vertical social mobility - researches of Glass (1949), Goldthorpe (1972) and Marshall (1988) - as well as controversy regarding the interpretation of their findings. The second part analyzes the reports of similar surveys in Serbia - researches of Janicijević (1972), Popović / Bogdanović (1988), Vuković (1989) and Lazić / Cvejić (1997 and 2012). It is concluded that the current social mobility in the Serbian society corresponds to Goldthorpe's findings for English society in 1972. Approximately a third of the highest class comes from the lowest class, but there are relatively small descending in the lower class. UK in the coming years, in the time after research of Goldthorpe, experienced the economic recovery and development, leading to maintaining upward mobility trend. Can Serbian society resolve the economic problems typical for a (semi) peripheral society and stop the downward trend of interclass permeability? It remains to be seen. But even with stopping this trend, it is difficult to believe that Serbia, in terms of intergenerational mobility, in the near future could be become an open society such as it was occurred during the sixties and seventies of the 20th century.
Socio-economic and political aspects of the transformation of post-socialist cities
Authors: Vukajlović Mile
Published: December 2022

City as a source of changes in a society is always in transformation. It builds, destroys and renovates. It alters its outer appearance, but people and social groups that inhabit it and use its resources in different ways and for different purposes, change as well. In periods of intense economic and political transition of the society as whole, such as post-socialism, cities gain one of the most important roles in the upcoming changes. This paper presents some of the socio-economic and political aspects of the transformation of the post-socialist cities, which directly influenced on the quality and the way of life of urban residents, as well as on the rest of the population that depends on the resources from the cities.

The development geoculture of the contemporary Balkans between the challenges of modernization and retraditionalization
Authors: Mitrović Ljubiša , Zaharijevski Dragana
Published: December 2022

The paper explores some peculiarities of the development geoculture of the postsocialist societies in transition on the basis of the results of empirical reserach conducted in Serbia, Macedonia and Bulgaria in 2003, 2007 and 2012. It focuses on the social attitudes of different social groups, and especially those of student population, on the current interethnic relations, Eurointegration modernization challenges and processes, the trends leading to dependent subdevelopment and retraditionalization. The results point to three tendencies intersecting in the given regional geospace: a) the tendency towards isolationism and retradiotionalism / retribalization, i.e. towards regression and return to premodern communities; b) the tendency towards dependent modernization and subdevelopment, and c) the tendency towards opening to the challanges of modernization and processes of European integrations. Our analysis shows that the third tendency is the most productive / the optimal one in drawing up contemporary development strategy / development policy. It is tightly intertwined with modern production forces, globalization processes, progressive reform tendencies and the culture of peace, and should therefore be insisted on in social processes directed by social agents. This is a result of the fact that the future of the Balkans does not lie in the focus on the past, in divisions and clashes, but in opening new development and civilizational perspectives for new generations, in the culture of peace and democratic cooperation and integration of this region.

Means of communication had lived trough a fast devolpment, in twenty-first century,largely contributing to the makeing of society wich gets a mark of mass society. In mass society of "le Bone's psycology" development of means of mass communication, with all positive options that it offers, many qustions and dilemas appear. From the cultural view two most important ones apear: despite the fact that means of communication repreaent the social need in what level can it be a direct danger to quality and value of national culture; and in what level unselective and uncritical accepting of imported content distans people from their own culture. Expansion of means of mass communication also caries negative and bad influece, becouse human state, in the sea of information, can be confused and destorted. Imported informations and entertamient shows can radicaly change social order wich reflectes on tradition and economicaland social flowes. Means of communication are an unseperable part of acculturation of a social sistem, but can be an instrument of manipulation with people and means for destruction of national identity, what is actualy happening.
Cultural and scientific evaluation in the social development
Authors: Đorđević Radomir
Published: December 2022

In this paper, author is dealing with the observation of Serbian historical science and its scientific-cultural mission in the process of transition and development. Culture, as general way of human life and behavior, is the necessary part of the permanent scientific complementarity. Historical science in such circumstances has the important part in creation of the cultural and scientific thought of an individual, which is in social sense, the basis of society development in general. Serbian historical science is also the part of the process, and therefore it passes through the time of transition itself. Researches and conclusions which it brings, could be very important (but problematic as well), viewing from the aspect of social development (if we mean by this all the causality that could appear over the whole social areal). Author critically concludes that in cultural and scientific sense, Serbian historical science brought Serbian society to the cultural and historical abyss because of its inadequate and non-scientific analysis and research.

Authors: Zvijer Nemanja
Published: December 2022

The aim of this text is to show how in socialist Yugoslavia popular culture used for the promotion of certain modernist forms as a general elements of social development. As examples of these forms are taken brotherhood and unity, gender equality, secularism, multiethnicity and national equality. It will be described and explained visual construction of these forms in partisan films. Such an approach, among other things, should provide insights into the mechanisms of ideological instrumentalisation of popular culture through film as one of its major segments. These mechanisms become more subtle as society develops.
Cultural institutions as factors of regional rural development
Authors: Jelić Sreten , Jovanović Tatjana
Published: December 2022

This paper discusses certain cultural institutions in the context of the regional rural development. Important role in rural areas have schools, cultural centers, churches and others. However, an increasing number of schools are closed or have a small number of students, and cultural centers are empty, collapsed, and at least be used for their intended purposes. Continued devastation of the network of institutions of education and culture in the countryside. It is emphasized the educational structure of the rural population in regions and areas, training of farmers, rural cultural life as one of the most important factors of rural regional development. The paper reviews some examples of local communities and villages in rural areas and suggests the potential of cultural institutions in the context of rural development. With the development of cultural institutions inevitably leads to the development of rural areas. What is the place of culture in the modernization of the countryside and the strengthening of its labor and social resources? In order to reduce regional disparities it is necessary to decentralize cultural policy in Serbia for faster and more dynamic regional rural development and transformation of the village. In that sense, the organization of cultural institutions is necessary to be established regionaly and by areas.
Svetozar Stojanović interpreting disintegration/break-up of SFR Yugoslavia
Authors: Radojičić Mirjana
Published: December 2022

The subject of this text is the interpretation of SFR Yugoslavia's disintegration/break-up offered by Serbian philosopher Svetozar Stojanovic in his works. The starting point that the author of the text has taken is the stand that the ex-Yugoslav crisis represented one of the major intellectual and moral challenges for researches of the social and political phenomena in the second half of the previous century. In the part of the text that follows, she focuses on the manner in which this Serbian intellectual responded to that challenge. Presenting in short his interpretation of the complex and long-lasting ex-Yugoslav case, the author provides arguments proving her point that the aforesaid interpretation, i.e. Stojanovic's works in which it was presented, constitues an integral part of, in terms of science and research, the highest-quality and the most relevant literature on the tragic end of the 20th century in the Western Balkans. The author concludes that, as such, those works represent, and are certainly to represent in future as well, a precious and inevitable matter for the reconstruction of the scientific truth on that turbulent part of the recent regional history.

This is a study on gender aspects of poverty, based on a three-part survey, which is being conducted on the territory of Serbia, from 2014-2016: desk research of the legislative and functional framework of institutional work that provide various social services and two groups of structured interviews with ethnographic elements of the providers and recipients of social services in rural areas. The action element of the research represents the basis for reform activities aimed at the social protection system that would create progress in this area. Non-governmental and state organisations; that are operating in the field of social protection and support; working in the situation of the incomplete transition from the system controlled by the state, to the system of small single organisations offering social support services, partaking in the market competition. We are going to show an abstract of socio-political frame in which these organisations operate, and the situation seen from the viewpoint of the representatives of the organisations.
Methodological innovations in the research on poverty
Authors: Savić Dalibor
Published: December 2022

This paper presents new methodological tendencies in the research on poverty. In this context, it problematizes the shortcomings of research approaches that equate poverty with economic deprivation (absolute and relative poverty), while preference is given to research approaches that promote multi-dimensional, dynamic and relational concept of poverty. In the study of social phenomena and processes related to poverty special attention is paid to the growing need to combine quantitative and qualitative methods (The mixed method), as well as the independent use of qualitative methods. Moreover, it also discusses the certain applied research strategies and methods aimed at solving specific problems faced by the poor (critical communicative methodology, participatory action research, etc).
Place and importance of culture in parliamentary parties of the Republic of Srpska
Authors: Ćorluka Bojan
Published: December 2022

Culture represents the realization of man as a generic being, implies humanism and represents the process of its realization. Culture can be a very important component of social movements, and especially the political ones. The notion of culture its self is sufficiently complex and multifaceted that it is difficult and impossible to pin down on only individual phenomena, processes or participators of rich cultural reality. Its significance is reflected in the fact that every social act, process, action or interaction, every product of human desires, spiritual forming or institutional structure is the content, condition and consequence of culture as an essential social phenomenon. The basic intent of the work is to illuminate the position of culture with the parliamentary parties of Republic of Srpska.

Migrations and cultural globalization
Authors: Vukajlović Mile
Published: December 2022

Migrants, people who significantly contribute to the cultural diversity of the modern world, generally want to integrate into the society of the country they came to, but if they are part of a larger homogeneous ethnic or religious group in the host country, they often seek a certain level of recognition of their collective cultural identity. Because of the different historical conditions in which states arose, they react to these demands as to maladaptation of immigrants, which results in a cultural conflict that usually leads to their marginalization, ghettoization and deprived position. The paper presents contemporary theoretical approaches to cultural globalization, and analyzes the impact of migration on the development of different models of multiculturalism, considering the large wave of migrants that moved to Europe since 2015.
Determining the investors' strategy during the COVID-19 crisis based on the S&P 500 stock index
Authors: Pekár Juraj , Brezina Ivan , Reiff Marian
Published: December 2022

Background: The most significant changes caused by the COVID-19 crisis were the sharp increase in working from home and the growing importance of e-commerce, which affected the development of some industries. This change also affects the investors' investment operations, which are based on analysis to ensure an unquestionable certainty of the invested financial amount and a satisfactory return. It is, therefore, interesting to analyze the possible return of the chosen investment strategy based on the optimization model of portfolio selection based on the CVaR risk measure. Purpose: The paper aims to present the possible use of the analysis of returns of effective portfolios constructed based on the optimization model of portfolio selection based on the CVaR risk measure during the crisis (COVID19) and the pre-crisis period. Study design/methodology/approach: Paper presents the impact of the COVID-19 crisis on investor decision-making through the CVaR risk measure, which was implemented on the historical data of the components of the Standard and Poor's 500 stock index (S&P 500) in the crisis period as well as in the pre-crisis period. Findings/conclusions: The presented approach based on the CVaR risk rate measure and the relevant portfolio selection model provides the investor with an effective tool for allocating funds to the financial market in particular segments in both monitored periods. Limitations/future research: Time series data are divided into two periods based on visible factors such as the number of COVID-19 cases. In future research, we aim to divide monitored periods based on unobservable factors influencing investors' decisions, such as bull or bear mood on the market.

Economía y fe en la Sevilla moderna. Los bienes de capellanías en el siglo XVII
Authors: Duro Garrido Rafael
Published: December 2022

El poder económico y la religión han ido de la mano a lo largo de la historia, pero pocas instituciones representaron esta simbiosis de forma tan clara como las capellanías. Fundadas para ofrecer misas por el alma de los difuntos, estos legados tuvieron una gran importancia en el ámbito hispalense e hispano de la Edad Moderna. Año tras año, grandes cantidades de bienes muebles e inmuebles fueron adjudicados a estas fundaciones con el objeto de procurar rentas que las sustentasen para poder pagar así las misas por el alma de los difuntos. A cambio de gozar de estas posesiones la Iglesia aseguraba la conservación de las propiedades a los fundadores, mezclándose así los intereses económicos con los espirituales. En este estudio abordaremos el caso de Sevilla del siglo XVII, una ciudad en la que estas prácticas fueron muy comunes.
El catálogo como taller: elaboración y usos de un catálogo del siglo XVIII de la biblioteca jesuita de la Casa Profesa de São Roque (Lisboa)
Authors: Palomo del Barrio Federico
Published: December 2022

El presente artículo examina algunos aspectos relacionados con el modo en el que los catálogos e inventarios de bibliotecas religiosas se concibieron y elaboraron en el contexto portugués de la Época Moderna. Para ello, centraremos el análisis en uno de los catálogos de la biblioteca de la Casa Profesa de São Roque en Lisboa, el Index Bibliothecae D. Rochi, organizado en el siglo XVIII para uso de los religiosos de la Compañía que ahí residían. Considerando las propias funciones esencialmente apostólicas (no académicas) que este establecimiento de la Orden jesuita desempeñaba, nuestro análisis no atenderá tanto al contenido de la librería y a los miles de volúmenes que reunía, como a la materialidad del catálogo y a las singulares características que conformaron su organización interna, convirtiéndolo esencialmente en un instrumento –a modo de taller– para la práctica de la escritura.
Ver más allá del texto: análisis material de los Pasquines Sediciosos de la Revolución de los Sastres en Bahía en el siglo XVIII
Authors: Duhá Lose Alícia
Published: December 2022

En 1798 aparecieron en la capital bahiana manuscritos que llamaban a la población a una «revolución» que implantaría la «República Bahiense». El gobernador ordenó iniciar un proceso durante el cual dos hombres fueron arrestados y sus bienes incautados por sospecharse que eran autores de «papeles sediciosos». Papeles, plumas, tintas y documentos de los investigados fueron analizados y comparados por expertos, para cursar una acusación contra Luís Gonzaga das Virgens. Este estudio se propone arrojar luz sobre las dificultades a las que enfrentan los investigadores de fuentes primarias: la falta de conocimientos básicos sobre el material documental y sobre Diplomática y Paleografía por parte de los que trabajan o investigan en los archivos es una de las razones de los errores. A partir del caso de los pasquines sediciosos de la Revolución de los Sastres, buscamos mostrar cómo el sistema de clasificación de documentos y la falta de acceso físico a los originales pueden inducir la interpretación del investigador.
The Pinnate Propeller
Authors: Simonsson Peter
Published: December 2022

The pinnate propeller is a programmable pitch propeller constructed for the purpose of eliminating transient cavitation, vibrations and noise, Two inherent qualities of the pinnate propeller, better vibration performance and reduced risk of fatigue may be utilized for the purpose of achieving better propulsive performance by allowing for a larger propeller diameter and thinner blades. The ability of the pinnate propeller to cope with very unhomogenous wake fields makes it possible to use ship shapes with lower resistance than for conventional propellers.

This paper combines the results of a paper read at the International Conference on Advances in Propeller Research in Gdansk Poland in February 1981, with some further model tests in order to show what gain in propulsive efficiency can be expected by using the pinnate propeller.
Design of Baltic Ferries for the Eighties, Propellers and Aft End Vibrations
Authors: Kanerva M. , Salminen R. A.
Published: December 2022

The Wartsila Shipyards are building seven Baltic ferries between, 1979 and 1981, four of them are prototypes. The Turku Shipyards are building six of these ferries. Some of the main design criteria are high propulsive efficiency at various sailing conditions, low vibration and noise level, enough power for ice-navigation without problems, good maneuverability. To meet these criteria a lot of attention has to be paid for the design of hull form, propellers and aft ship construction.

Results of theoretical propeller calculations are presented. Model test results for three prototype ferries are presented, self-propulsion, cavitation and pressure pulse measurements. Comparative measurements were performed with a convential and a so called highly skewed c.p. propeller model.

Calculations of natural frequencies and modes and forced vibrations caused by propeller pressure pulses are presented. Estimates made for the vibration level are presented.

Forced vibration tests made with a vibration generator are presented.

During the sea trials the cavitation phenomenon has been photographed, pressure pulses and vibrations have been measured. Comparisons between theoretical propeller calculations, model tests and full scale measurements are presented.

Also vibration calculations, forced vibration tests and sea trial measurements are compared. Conclusions are drawn of the applicability of special c.p. propellers to reduce the vibration level in ice strengthened high-powered ferries.
RESISTENCIA FENOTÍPICA Y GENOTÍPICA EN LOS PATOTIPOS AIEC, STEC Y EAEC DE E. COLI
Authors: Ruiz Herrero Eduardo , Caro Vergara Maria Rosa , Ortega Hernández Nieves
Published: December 2022

Escherichia coli is a bacteria that is very present in our daily life, as a commensal or pathogenic organism. There are a large number of pathogenic strains capable of producing diseases, being of great importance for public health those strains transmitted through food, causing foodborne infections with great morbidity. In some cases, the strains that cause these outbreaks can be highly pathogenic, causing high mortality and very serious health implications for those affected. In this study, we focused on investigating the presence of strains transmitted through food of meat origin that belong to one of the 3 pathotypes investigated (STEC, AIEC and EAEC). On the other hand, we proposed to investigate the antibiotic resistance of E. coli strains isolated from meat foods. Our results showed the high phenotypic resistance of the great majority of E. coli strains isolated in this study, posing a serious problem for public health. This makes it necessary to maximize vigilance and control measures for these pathotypes throughout the food chain. It is also necessary to be cautious in the use of antibiotics, since their inappropriate use would lead to an increase in the therapeutic difficulty of infections, threatening to put an end to a century of medical advances.

Escherichia coli es una bacteria que está muy presente en nuestro día a día, como comensal o como forma patógena. Hay gran cantidad de cepas patógenas capaces de producir enfermedades, siendo de gran importancia para la salud pública aquellas cepas vehiculadas a través de los alimentos, provocando toxiinfecciones alimentarias con gran morbilidad. En algunos casos, las cepas que provocan estos brotes puedes ser muy patógenas ocasionando una gran mortalidad y con repercusiones muy graves para los afectados. En este estudio nos centramos en investigar la presencia de cepas vehiculadas a través de los alimentos de origen cárnico que formen parte de alguno de los 3 patotipos investigados (STEC, AIEC y EAEC). Por otro lado, planteamos investigar la resistencia a los antibióticos que presentan las cepas de E. coli aisladas en los alimentos cárnicos. Nuestros resultados han evidenciado la elevada resistencia fenotípica que presentan la gran mayoría de las cepas de E. coli aisladas en este estudio, planteando un grave problema para la salud pública. Esto hace necesario extremar las medidas de vigilancia y control de estos patotipos a lo largo de la cadena alimentaria. También es necesario ser cautos en el empleo de antibióticos ya que si se hace un uso inadecuado de los mismos provocaría un aumento en la dificultad terapéutica de las infecciones, amenazando con acabar con un siglo de avances médicos.
El futuro de la interculturalidad en Educación Primaria según la LOMLOE: análisis desde la enseñanza de ELE
Authors: González Plasencia Yeray
Published: December 2022

En este trabajo se elabora un estudio del tratamiento de la competencia intercultural en el nuevo currículo de Educación Primaria, el cual comenzará a implementarse en el curso 2022-2023. Para ello, se abordan los tres constructos que articulan el currículo: el marco pedagógico, el perfil de salida y las áreas o ámbitos. En cuanto al perfil de salida, se estudian en profundidad los descriptores operativos; por lo que respecta a las áreas o ámbitos, se atiende a las competencias específicas y a los criterios de evaluación. Las cinco categorías que constituyen el análisis emergen de las características atribuidas a la competencia intercultural en la enseñanza de lenguas extranjeras, esto es, los componentes cognitivo, afectivo, procedimental, crítico e identitario. El artículo concluye identificando fortalezas y debilidades del tratamiento de la interculturalidad en la propuesta educativa, y se sugieren acciones para la segunda concreción del currículo. Entre estas, destacan las necesidades de trabajar explícitamente la competencia simbólica y la capacidad para negociar significados culturales; de especificar cómo habrá de afrontar el alumnado la otredad; de atender a la configuración de la identidad de los estudiantes; y, finalmente, de fortalecer la formación del profesorado en el ámbito de la interculturalidad.

Historical and Modern Responses to Plague Epidemics
Authors: Carnell Hugo
Published: December 2022

Despite its long history, plague has not been an internationally significant
disease since the mid-twentieth century, and it has attracted minimal modern
critical attention. Strategies for treating plague are generally outdated and of
limited effectiveness. However, plague remains endemic to a few developing
nations, most prominently Madagascar. The outbreak of a major plague epidemic
across several Madagascan urban areas in 2017 has sparked a wider discourse
about the necessity of improving global preparedness for a potential future
plague pandemic. Beyond updating treatment modalities, a key aspect of improving
preparedness for such a pandemic involves a process of sophisticated review of
historical public health responses to plague epidemics. As part of this process,
this article outlines and compares public health responses to three separate
epidemics from the early modern era onwards: Marseille in 1720–22, San
Francisco in 1900–04 and Madagascar in 2017. Based on this process, it
identifies three key themes common to successful responses: (1) clear, effective
and minimally bureaucratic public health protocols; (2) an emphasis on combating
plague denialism by gaining the trust and cooperation of the affected
population; and (3) the long-term suppression of plague through the minimisation
of contact between humans and infected small mammals.
Critical Roles of Refugee Leaders and Service Providers in the Gender-based Violence (GBV) Help-Seeking of Refugee Survivors
Authors: Robles Lisette R.
Published: December 2022

Gender-based violence (GBV) is a complicated challenge embedded in displaced
people’s lived experiences throughout the conflict displacement cycle.
Despite the awareness of existing institutionalised help-seeking referral
pathways, these do not necessarily translate to the full utilisation of such
services. This paper examines the critical role of refugee leaders and service
providers in potentially enabling and realising a GBV survivor’s
help-seeking. By adapting a meso-level analysis, it attempts to explain how
social networks built within conflict and displacement contribute to responding
to GBV. Based on the review of collected interviews in 2019 from refugee leaders
and service providers working with South Sudanese refugees in selected
settlements in Uganda, the paper reflects on the importance of network, norms
and trust in effectively responding to GBV in conditions of conflict-affected
displacement.
Historicising Humanitarian Action
Authors: Taithe Bertrand , Paih Mickaël le , Weissman Fabrice
Published: December 2022

This roundtable was convened on 5 July 2022 and built on five years of
collaborative work in Cambodia and ongoing collaborations within the Centre de
Reflexion sur l’Action et les Savoirs Humanitaires (CRASH) at
Médecins Sans Frontières (MSF) between Bertrand Taithe,
Mickaël le Paih and Fabrice Weissman. The central question raised in this
discussion relates to two profoundly intermeshed issues for humanitarian
practitioners and organisations: the use of history for humanitarian
organisations, and the need for them to preserve and maintain archives.
Numerical study of the low- threshold nanolaser based on quasi-bound states in the continuum supported by resonant waveguide grating structures

As a nanoscale coherent light source, semiconductor nanolaser is a key device for future optoelectronic integrated chips. The obstacle of further miniaturization of the nanolaser is that the loss increases rapidly with the decrease of cavity volume. The bound states in the continuum (BICs) can overcome the high radiative loss. Here, we propose a nanolaser based on quasi-BIC mode supported by all-dielectric resonant waveguide grating (RWG), which can effectively reduce the threshold of nanolaser. The quasi-BIC mode of the waveguide can be excited when the traditional two-part grating becomes a four-part grating. The laser behavior of the quasi-BIC is studied by finite difference-time-domain (FDTD) numerical simulation. The results show that the threshold of the naolaser based on four part-grating RWG is 20.86% lower than that of nanolaser based on two part-grating RWG when subjected to TE-polarized light irradiation. For the TM-polarized light irradiation, the threshold is 3.3 times lower than the threshold for the nanolaser based on four part-grating RWG. We also find that the threshold of the nanolaser under TE-polarized light irradiation is about one order of magnitude lower than that under TM-polarized light irradiation. Because the electric field of the structure is well confined inside the waveguide layer under TE-polarized light, which can enhance the interaction between light and gain materials and reduce the threshold of nanolasers.
