Investigación de la ética periodística en España (2007-2018). Evolución y prospectiva
Authors: Redondo-García Marta , Caffarel-Serra Carmen
Published: June 2022

Este trabajo realiza una radiografía del estado de la investigación sobre ética periodística en España mediante el análisis de las tesis doctorales, artículos científicos, proyectos I+D y grupos dedicados a la materia a lo largo de la década comprendida entre 2007 y 2018. Se recurre al análisis de contenido del corpus registrado por el proyecto MapCom y compuesto por 3.518 unidades para encontrar que la ética, a pesar de la posición central que ocupa en la profesión periodística, representa tan solo un 1,4% de la actividad científica. Una producción que está atomizada en torno a muy pocas universidades y a un número limitado de profesores con gran experiencia en la investigación de la deontología periodística. Además, en este campo la cooperación académica entre universidades y la internacionalización resultan residuales. Respecto al objeto de estudio se observa que el entorno digital está falto de un volumen suficiente de producción científica que encare los dilemas y problemas éticos a los que se enfrentan los periodistas en este ámbito protagonista en la comunicación actual. Entre los hallazgos destaca también que la investigación en ética plantea algunas especificidades en el uso de la metodología privilegiando el empleo de métodos discursivos (fundamentalmente entrevistas a profesionales), frente al análisis de contenido que resulta el método dominante.
La representación de la Unión Europea en la prensa para residentes comunitarios de la Costa del Sol
Authors: García-Galindo Juan-Antonio , Meléndez-Malavé Natalia , Cuartero Antonio
Published: June 2022

La presente investigación aborda la imagen y el concepto de Europa que reflejan los principales medios de comunicación para residentes comunitarios que se editan en la Costa del Sol. Con este fin se han seleccionado una serie de piezas publicadas entre 2016 y 2018 que tratan esta cuestión, procedentes de cinco medios para residentes británicos, alemanes y suecos, por ser representativos de las poblaciones más numerosas y de los tres idiomas más utilizados en los medios de la zona. Los resultados muestran una clara vocación europeísta en la prensa para residentes comunitarios en la Costa del Sol, sin que por ello dejen de manifestarse críticos con determinados aspectos de la Unión Europea (UE). Además, el análisis de las secciones, temas y fuentes estudiados nos permite constatar el interés que tienen por todo lo relacionado con Europa en la cantidad de informaciones que publican, aunque éstas no siempre ocupen el espacio más relevante, y que suelen estar más vinculadas a las cuestiones institucionales de la UE que a la noción de Europa como espacio cultural común.
George Floyd and cosmopolitan memory formation in online networks: A report from Northern Europe
Authors: Robinson Jessica-Yarin
Published: June 2022

This work analyses the presence and management As personalized digital networks have increased in cultural and political relevance, there is a more urgent need to understand their role in democratic memory-formation. Moreover, scholars have suggested that, in a globalized digitalized age, collective memory could extend to transnational publics. This study aims to advance the understanding of memory on global social networks by investigating the way the death of George Floyd in the summer of 2020 was treated and understood by Twitter-users outside the United States. Using a combination of big data and contemporaneous qualitative interviews with users in Norway, Sweden, and Denmark, the paper brings the concept of cosmopolitan memory into the social media era. The study finds that users fused the event and its aftermath with observations of injustice in their own countries. However, this process operated differently among users of different ideological outlooks. Another key finding is that users on the radical right resented the uptake of the event as a cosmopolitan memory, and employed techniques termed as “combative counter-memory”.
Inherited anti-Jewish narratives in the current disinformation media. Case study from Slovakia
Authors: Tkáčová Hedviga
Published: June 2022

This paper affords an insight into an important phenomenon related to the current worldwide increase in xenophobic behavior. In the past as well as in the present, the issue of anti-Semitism was the topic to be discussed; we note the dangers of the return and growth of populist and racist political parties and social movements while observing similar discussions today, especially in Eastern Europe (including Slovakia). They are linked to the current anti-vaccination and anti-war movements. This study had three objectives: (1) To present the critical anti-Semitic narratives that survived communism and were re-mediated after the establishment of an independent Slovakia in 1993; (2) to identify inherited mechanisms that continue to determine the forms of negative attitudes of Slovaks towards Jews; (3) to identify and analyze current narratives representing new forms of digital anti-Semitism in the current disinformation media in Slovakia. This paper employs a structured interview method with thirteen Slovak multi-disciplinary experts to research crucial inherited and current anti-Semitic narratives. Our research identified ten anti-Semitic narratives that remain in the current disinformation media. The research also points to two former mechanisms from the communist era that still influence the attitudes of Slovaks towards Jews. This also influences the nature of contemporary anti-Semitism: the generational influence, under which intolerant attitudes pass from generation to generation, and the influence of (inherited) power and economic “remorse”, accompanied by the common notion of the “exploitation” of countries (including Slovakia) by the Jewish community. Finally, four new and current narratives have been identified through structured interviews with experts, determining the nature of current digital anti-Semitism.
Análisis y detección de los trols en el perfil de Twitter de El País España
Authors: Cenizo Coral
Published: June 2022

Los trols son una realidad cada vez más presente con la que conviven los usuarios de Internet. El presente estudio pretende confirmar si los trols son una amenaza real en España y, más concretamente, en el perfil de Twitter del periódico más leído de la nación: El País. Mediante el análisis de 767 tuits, se buscaba analizar la frecuencia con la que intervienen los trols en el perfil El País España, caracterizar —en cuanto a sexo y tipología— los trols que intervinieron en esta cuenta de Twitter y comprobar si existe una relación entre el ratio de engagement de las publicaciones y el número de comentarios trolling. Los resultados confirmaron que los trols están muy presentes en el perfil de Twitter de El País España, con un mayor protagonismo de los trols anónimos de tipología hater. Además, el engagement presenta una correlación positiva muy fuerte con el número de comentarios trolling hasta el punto de que es posible predecir este ratio, utilizando para ello el número de comentarios protagonizados por trols. La investigación aporta información de valor que puede resultar de utilidad tanto a nivel teórico como práctico debido a las implicaciones y el carácter innovador que posee.
La construcción estética y narrativa de los relatos enmarcados en Un monstruo viene a verme
Authors: García-Pedreira Rocío
Published: June 2022

El objetivo principal de este artículo es analizar la construcción estética y narrativa de los relatos enmarcados de la novela juvenil Un monstruo viene a verme, escrita por Patrick Ness, en su reescritura para la gran pantalla, dirigida por Juan Antonio Bayona y estrenada en 2016. Aunque la película está realizada principalmente mediante imagen real, los dos primeros relatos que incluyen los cuentos que un monstruo le narra al joven protagonista, Conor, para ayudarle a superar la inminente muerte de su madre a causa de un cáncer, fueron realizados mediante animación digital por el estudio catalán Headless. Se plantea un diseño metodológico mixto basado en el análisis de contenido cuya aplicación ha permitido el estudio comparativo de los capítulos/secuencias del libro y la película, para luego focalizar la atención en la construcción estética y narrativa resultante del trasvase de los relatos del monstruo a la gran pantalla. El trabajo vislumbra las posibilidades de la hibridación de la imagen real y la imagen animada en la producción de películas de estética mixta para la traslación de los mecanismos del lenguaje literario al discurso cinematográfico con el propósito de mantener un grado alto de dependencia constitutiva.
Online reputation management in Spanish cancer patients’ associations: a proposal model
Authors: Medina-Aguerrebere Pablo , Gonzalez-Pacanowski Toni , Medina Eva
Published: June 2022

Cancer patients’ associations have become valid public health players because they help patients to face this disease from physical, emotional and social perspectives. Some of these associations resort to social media platforms not only to improve their relationships with patients, but also to promote their own brand. This paper seeks to understand how Spanish cancer patients’ associations manage their social media platforms to promote their brand. To do that, we conducted a literature review about health communication; we considered 48 indicators to analyze how 107 associations belonging to the Spanish Group of Cancer Patients (Gepac) managed Facebook, Twitter, Youtube and their corporate website for branding initiatives; and we proposed a communication model for branding cancer patients’ associations on these platforms (MedPac Model). We concluded that Spanish cancer patients’ associations prioritize medical information but not brand-related elements, they lack the economic and human resources to produce a quality content, and they have not yet implemented a true corporate communication approach.

Analysis of Factors Affecting Damage of the Concrete Check Dams Based on the Exterior Condition Assessment
Authors:   Crisis and Emergency Management: Theory and Praxis, Lee Jin Ho , Kim Suk Woo , Lee Kwang Youn , Chun Kun Woo , Bae Hyun Seok
Published: June 2022

This study assesses the exterior condition of concrete check dams and analyses the factors such as the watershed area, check dam length, deposit length, and elapsed years which can affect the damage of concrete check dams. After the survey of 426 concrete check dams built in Gangwon province, we found that although all the factors have statistical significance, the elapsed year of construction is most closely related to the condition of the dams. In other words, the elapsed year is the most influential factor among the analysed ones; the watershed area(R=-0.121, p<0.05), dam length(R=-0.183, p<0.01), deposit length(R=-0.274, p<0.05), and elapsed years(R=-0.852, p<0.01). In addition, it is considered that the detailed inspection cycle of dams can be set as 15 years after construction because the assessing point less than 2.5 which indicates the need of urgent repair and reinforcement starts to appear after 15 years of construction. Since this study is limited to impermeable concrete dams, the supplementary research on dam types and materials is required.
Endodontic Challenges in the Management of Multiple Pulp Stones and Root Canal Calcification - A Case Report
Authors: Melia Heptania  , Wandania Farahanny  , Trimurni Abidin
Published: June 2022

Root canal calcification is currently a challenging and interesting case for endodontists. Removing microorganisms and their by-products from the root canal system is the goal of root canal treatment. Worse outcomes from root canal procedures can occur due to root canal calcification, as it can block access to the root canal and hinder cleaning and shaping. Iatrogenic errors may occur in the treatment of such cases which will lead to failure of endodontic treatment. This case report describes a 20-year-old woman with multiple pulp stones in the pulp chamber of the mandibular left first molar. In addition, there were also calcified root canals in the mesiolingual and mesiobuccal canals. The patient had asymptomatic irreversible pulpitis and had to undergo endodontic treatment. Several challenges were faced in this case. The initial challenge was to determine the location of the pulp stone in the pulp chamber. Radiographs taken from multiple angles, as well as a direct assessment of the cavity during access preparation, addressed this initial challenge. Retrieval of the pulp stone which in this case is the embedded type that was carried out by grinding it with the help of an ultrasonic tip. Other difficult challenges were avoiding perforation of the pulp chamber floor during treatment, especially when removing the pulp stone, and identifying the location of the orifice. With clinical knowledge, magnification aids and ultrasonic tips, successful treatment in this challenging case was achieved.

Calcific metamorphosis, sometimes known as pulp canal obliteration (PCO), is the extensive formation of tertiary dentin in the pulp chamber leading to circumferential narrowing of the pulp chamber and root canal.[1] According to the AAE (American Academy of Endodontics), PCO is radiographic evidence of increased dentin production mainly in response to trauma. The result is a calcified canal and does not necessarily indicate pulp disease.[2] Pulp calcification is a common occurrence. The incidence varies, but overall it can be estimated that 50 % of teeth have one or more calcifications.[3]

There is no evidence to explain whether pulp calcification is a pathological process associated with various forms of injury or natural phenomena.[3] In general, the pulp chamber becomes progressively smaller and often very small, a phenomenon known as calcified metamorphosis or obliteration of the pulp canal. Dentin can be accelerated by caries, trauma, abrasion, restoration, and periodontal disease and is not uniform.[1]

Calcifications are divided into denticle (pulp stones) and diffuse (linear) calcifications. Pulp stones are divided into free, attached, and embedded types. Pulp stones tend to be found in the coronal pulp, and diffuse calcifications are found in the radicular pulp. It has been speculated that the nidi of calcification arise from degenerating nerves or blood vessels, but this has not been proven.[1

The Association With Recurrence in Breast Cancer Patients According to the Preoperative Blood Composition Ratio and Postoperative Pathological Results
Authors: Shin Hyun Sub , Lee Jong Eun , Hong Sung Hoon , Han Sun Wook , Heo Nam Hun , Kim Sung Yong
Published: June 2022

Purpose: This study aimed to determine the correlation between various clinical results, including recurrence in patients with breast cancer, and preoperative blood composition ratio and postoperative pathological results.Methods: A total of 444 patients who underwent surgery were included, and the neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), monocyte-to-lymphocyte ratio (MLR), and postoperative pathological results were classified into postoperative cancer stages to confirm the association with various clinical results, including recurrence.Results: The median age of the patients was 51 years. The stages were divided into 1, 2, 3, and 4. Additionally, stages 1 and 2 comprised one group and stages 3 and 4 comprised another group. The cut-off values of the NLR, PLR, and MLR were confirmed to be 1.43, 158.84, and 0.21, respectively. It was noted that the association with recurrence was higher in the group with hormone receptor negative (p<0.001), higher stage (p<0.001), and underwent neoadjuvant chemotherapy (p<0.001). In the association with blood composition ratio and recurrence, survival was high in the PLR group with a high cut-off value (p=0.004). There was no significant relationship in the NLR and MLR groups. In the disease-free survival and overall-survival curves, only the PLR group showed a significant association of 0.003 and 0.001, respectively. The NLR and MLR groups did not show any significant result.Conclusion: No significant association with recurrence and mortality was confirmed in the NLR and MLR groups. However, the preoperative blood test in the high PLR group showed recurrence and mortality rate were high.
Prognostic Significance of Fibrotic Focus and Tumor Infiltrating Lymphocytes in Breast Cancer According to Molecular Subtypes
Authors: Lee Do Bin , Oh Hoon Kyu , Lee Na-Rang , Park Sung Hwan , Jeong Young Ju
Published: June 2022

Purpose: This study aimed to analyze the association between fibrotic focus (FF) and tumor-infiltrating lymphocytes (TILs) and to determine the prognostic significance of FF and TILs in the breast according to its molecular subtypes.Methods: The study included patients who underwent surgical treatment for breast cancer, for whom tissue samples were available. FF within the tumor and TILs in breast cancer tissues were evaluated. Clinicopathological characteristics were reviewed from medical records.Results: FF and TILs were present in 31.3% and 81.7% of the patients, respectively. FF and TILs showed a positive correlation. FF were significantly associated with tumor size, lymphovascular invasion, regional lymph node metastasis, and tumor stage. TILs were significantly associated with menopausal status, histologic grade, tubule formation, nuclear grade, mitosis, human epidermal growth factor receptor 2 (HER2) overexpression, molecular subtype of breast cancer, and the number of cluster of differentiation 8+ T cells. In TIL-positive cases, FF were significantly associated with tumor size, regional lymph node metastasis, extranodal extension, lymphovascular invasion, tumor stage, recurrence-free survival, and overall survival (OS). Based on HER2 overexpression status, TILs were significantly associated with tumor size, tumor necrosis, histologic grade, estrogen receptor status, and epidermal growth factor receptor expression in HER2-negative breast cancer. Further, in HER2-negative breast cancer, OS and recurrence-free survival were significantly associated with FF. The OS of FF-positive patients was significantly shorter than that of FF-negative patients.Conclusion: Our study showed an association between FF and TIL levels in breast cancer, indicating that FF are associated with poor prognostic factors for breast cancer and poor OS, and that TILs are associated with HER2 overexpression. However, further studies are needed to elucidate the interactions between FF and TILs in breast cancer.

El propósito de esta investigación, de tipo descriptiva, consistió en describir las estrategias socializadoras y de alfabetización económica en una muestra conformada por 40 familias, 34 biparentales y 6 mo-noparentales, de estrato socioeconómico medio de la ciudad de Barran-quilla. Las estrategias y prácticas de alfabetización económica que los padres suelen utilizar son: el conversar acerca del uso del dinero, estra-tegias de fomento del ahorro, salir con los hijos de compras y la prác-tica de ahorro más común: ‘la alcancía’. Padres e hijos de las familias pertenecientes al estrato medio poseen conocimientos en economía como el rol del dinero, su ciclo y circulación y el rol del estado, entre otros elementos. En cuanto a la actitud hacia el endeudamiento de los padres de familia, se observó que la mayor parte de ellos tiende a ser de carácter austero y poseer hábitos de compra de carácter reflexivo.
Policies to reduce instability
Authors: Brunstein Luis
Published: June 2022

The current stabilization policy adopted by many Latin American countries demands a restrictive monetary policy coupled with a conservative fiscal policy. While these policies have been adapted to suture financial fragilities, they have not been able to significantly improve the levels of structural poverty and unemployment, rendering the approach vulnerable to political risk. By exploring the case of Argentina, this paper argues that the presence of such risk forces the government to adopt a heterodox, eclectic and very flexible approach to policy formation that may maximize its chances to achieve long term social objectives.
Credit channel in developing countries: the case of Colombia
Authors: Corredor Velandia César Augusto
Published: June 2022

This paper uses a panel data set containing monthly information from the balance sheets of 20 banks between 1995 and 2003. It follows an estimation procedure proposed by Arellano and Bond which applies autocorrelation into panel data using a Generalized Method of Moments (GMM) estimator. The model includes particular characteristics to determine the existence of a bank lending channel including: size, liquidity, capitalization and foreign capital. The bank lending channel literature argues that differences in the characteristics and initial position of banks are reflected in their ability to offset the effects of a tightening monetary policy. It has been proved that in Colombia there is a negative response of loans to changes in the interest rate, but bigger, liquid or capitalized banks are better able to maintain the same level of loans in the face of a tightening monetary policy.

The relevance of Duesenberry consumption theory: an applied case to Latin America
Authors: Parada Corrales Jairo , Bacca Mejía William
Published: June 2022

In this paper we examine the to-date relevance of Duesenberry´s Consumption Theory through an applied case to four economies in Latin America: Mexico, Brazil, Argentina and Colombia. Using annual time series of these countries we show that some empirical evidence of Duesenberry´s theory still holds and should not be discarded in modern macroeconomics as it has happened in regular macro text books in mainstream economics. Duesenberry´s theory includes important institutional factors that cannot be replaced by the permanent income hypothesis or the life cycle hypotheses. In the paper we explore different specifications of the consumption functions based on the relevant literature. Final conclusions are presented.
O novo conservadorismo brasileiro e a educação: Mapeando suas linhas de força
Authors: Teixeira Pedro Pinheiro , Henriques Adrian
Published: June 2022

Na última década, o Brasil viu crescer demandas por aumento da ordem e a defesa de valores morais tradicionais, no âmbito do chamado novo conservadorismo brasileiro. Lideranças e grupos religiosos conservadores e neoliberais se destacam, atuando em diferentes linhas de frente na política e nas relações sociais, incluindo a educação. A partir desse contexto, o artigo objetiva mapear as diferentes manifestações, ações e agentes do novo conservadorismo brasileiro no campo educacional, por meio de uma reflexão teórica e da construção de um mapa conceitual. Inicialmente, discutimos diferentes correntes conservadoras, em especial o novo conservadorismo nos EUA e suas influências no Brasil. A partir de Almeida (2017), delineamos um mapa conceitual do novo conservadorismo na educação, ressaltando quatro linhas de força: moral, econômica, securitária e socialmente intolerante. Elas possuem conexões entre si e se articulam de acordo com os interesses de seus defensores. No plano educacional, propagam uma visão tecnicista, bancária e autoritária de educação, enfatizando a atuação da família, cerceando o trabalho docente e a autonomia discente. Concluímos que essas múltiplas linhas de força levam a reveses significativos na construção de propostas educativas plurais, afetando a prática pedagógica, currículos e formação de professores.

Published: June 2022

El presente estudio busca obtener evidencias de validez y confiabilidad de la Escala de Involucramiento Parental: Actividades de cuidado y socialización en una muestra de padres peruanos de niños y niñas preescolares. Para ello, se realizó una traducción y armonización del lenguaje del instrumento a partir de su versión en inglés al español, para luego aplicar la nueva versión a un grupo de 420 padres y 420 madres de niños y niñas de cinco ciudades. La evidencia de la estructura interna se evaluó a través de un análisis factorial confirmatorio multigrupo, utilizando el método de máxima verosimilitud para examinar la estructura de los 26 ítems originales. Durante el análisis, se procedió a la eliminación progresiva de los ítems con bajas cargas factoriales hasta encontrar un modelo con adecuados indicadores de ajuste [χ2 (531) = 822.82; p < .001; χ2 /gl = 1.550; gfi = .90; cfi = .95; tli = .94; rmsea = .036, ic 90 % = (.031-.041), p close = 1.000, srmr = .05]. El resultado fue una escala de 18 ítems distribuidos en las cinco dimensiones originales, cada una con confiabilidad por consistencia interna alfa de Cronbach entre .66 y .78 y coeficientes omega entre .70 y .75. La confiabilidad entre evaluadores estuvo entre .67 y .88. Los alcances y limitaciones del estudio son discutidos teniendo en cuenta la importancia de contar con instrumentos de medición del involucramiento paterno, relativo al materno, que consideren las perspectivas de padres y madres en el contexto peruano.
Metafilozofia Władimira Erna
Authors: Herbich Tomasz
Published: June 2022

Vladimir Ern is often seen as a philosopher that focused mainly on defining the characteristic featuresof Russian philosophy. When his philosophical works are interpreted in such a way, the biggeststress is being put on the fact that he formulated a certain idea of national philosophy, which wasthen transformed by him into a kind of national ideology during the World War I. The article triesto show, that Ern should be treated first of all as an author who considered metaphilosophical issues(and that this fact distinguishes him from the majority of the philosophers of Russian religiousphilosophicalrenaissance, who were mainly interested in solving the metaphysical issues). He focusedon metaphilosophy because he was convinced, that philosophy is a field of the battle between twonotions of the essence of philosophical knowledge which exclude one another. Seen as such, hisphilosophy should be interpreted as an attempt to find a proper way in philosophy and to rejectthe wrong way. The authentic way, which gives a correct answer to the question concerning theessence of philosophical knowledge, was seen by him in Christian Platonism. He tried to show, thatin the works of Plato can be found a certain theory of the spiritual development of man, whichis at the same time a genuine epistemology that shows the way of true philosophical knowledge.
Big data a problem reprezentacji poznawczej
Authors: Iwasiński Łukasz
Published: June 2022

In this article, the author reflects on Big Data analytics in the context of the problem of cognitive representation. There are many voices declaring that the era of Big Data has brought a radical breakthrough in human cognitive abilities. Some – especially in the world of business and marketing, and to a lesser extent in the field of science – argue that for the first time we can reach a clean, objective picture of reality and keep track of its changes. The article is a critical commentary to this thesis. In Big Bata analytics, cognitive activities are assessed not from the point of view of their compliance with reality, but the possibility of achieving set goals. Big Data mining can be, and often is, an important tool for reality control and forecasting – which does not mean it can discover objective truth and create accurate representations of reality.
Uwagi o genezie i koncepcjach metafilozofii
Authors: Szubka Tadeusz
Published: June 2022

Although reflection on the nature of philosophy has constituted an integral part of this discipline from its beginnings, the term „metaphilosophy” referring to such a reflection only made its first appearance in the middle of the twentieth century. In the course of discussions concerning the book by C.J. Ducasse about the subject-matter and method of philosophy, the term was introduced in the United States by C.G. Hempel and M. Lazerowitz, and in Poland by M. Choynowski. Subsequently, two different metaphilosophical programs, which disseminated this category, were put forward by Lazerowitz and J. Kalinowski. They had dissimilar objectives and assumptions, though for both of them a crucial problem was the diversity of philosophical conceptions and persistent disagreements in philosophy.
Metafilozoficzne aspekty współczesnej myśli kosmologicznej

Published: June 2022

The objective of this article is to provide an answer to the question as to how to philosophize within the context of science, which constitutes a more specific version of one of the essential metaphilosophical questions: how should one philosophize? A compelling answer to such inquiries was proposed at the end of the 20th century by the Cracow philosophers of nature and went under the name of „philosophy in science” research program. In this elaboration, on the basis of findings originating in the cosmological domain, I analyze to what extent this is indeed an innovative answer to the metaphilosophical question stated above – that is how to philosophize within the context of science.

Construction of partially degenerate Bell–Bernoulli polynomials of the first kind and their certain properties
Authors: Khan Waseem A. , Kamarujjama Mohammad , Daud
Published: June 2022

Various applications of degenerate polynomials in different areas call for the thoughtful study and
research, and many extensions and variants can be found in the literature. In this paper, we introduce partially degenerate
Bell–Bernoulli polynomials of the first kind and investigate their properties and identities.
Furthermore, we introduce a generalized form of partially degenerate Bell–Bernoulli polynomials of the first kind
and derive some interesting properties and identities.
The results obtained are of general character and can be reduced to yield formulae and identities
for relatively simple polynomials and numbers.
Analyzing and forecasting financial series with singular spectral analysis
Authors: Makshanov Andrey , Musaev Alexander , Grigoriev Dmitry
Published: June 2022

Modern techniques for managing multidimensional stochastic processes that reflect the dynamics of unstable environments are proactive, which refers to decision making based on forecasting the system’s state vector evolution. At the same time, the dynamics of open nonlinear systems are largely determined by their chaotic nature, which leads to a violation of stationarity and ergodicity of the series of observations and, as a result, to a catastrophic decrease in the efficiency of forecasting algorithms based on traditional methods of multivariate statistical data analysis. In this article, we make an attempt to reduce the instability influence by employing singular spectrum analysis (SSA) algorithms. This technique has been employed in a wide class of applied data analysis problems formulated in terms of singular decomposition of data matrices: technologies of immunocomputing and SSA.

The aim of this study was to identify the impacts of different driving factors on terrestrial ecosystem evolution. The Yellow River Basin was selected as the study area, of which terrestrial ecosystem was deeply affected by climatic change and human activities. We constructed four scenarios (including without any impacts, affected by climate change, by human activities and by both impacts), and the discrepancies between them reflected the impacts of climate change or human activities. Based on this, the future land use simulation model was used to simulate the land use distribution under the four scenarios, and then, the ecosystem services values (ESV) and landscape patterns index were evaluated. The results indicated that affected by climate change during 1995–2015, the Mean Patch Area of the forestland decreased by 0.19% and the landscape patterns became fragmented. Meanwhile, the total ESV decreased by 0.03 billion dollars and the ecosystem regulation services were weakened. Under the influences of human activities, the Contagion index decreased by 1.71% and the landscape patterns became dispersed. Simultaneously, the total ESV increased by 0.56 billion dollars, but the function tends to be unitary. In addition, these effects showed great spatial heterogeneity. This study provides scientific support for ecological protection in the Yellow River Basin.
Inverse of Berge’s maximum theorem in locally convex topological vector spaces and its applications
Authors: Li Wen , Li Deyi , Feng Yuqiang
Published: June 2022

In this paper, the inverse of Berge’s maximum theorem is established in a locally convex topological vector space. Using this result, the generalized Gale–Nikaido–Debreu’s lemma and the generalized coincidence point theorem are derived from the equilibrium theorem of generalized games. By combining the inverse of Berge’s maximum theorem with the generalized coincidence point theorem, the equilibrium theorem of the generalized game is obtained immediately. Finally, we show that Fan–Glicksberg’s fixed point theorem and von Neumann’s lemma can be derived directly from the coincidence point theorem.
Multilingual pedagogies in first versus foreign language contexts: a cross-country study of language teachers
Authors: Calafato Raees
Published: June 2022

This article reports on a study that used the online MULTITEACH questionnaire to examine the relationship between the multilingual pedagogies 111 language teachers, employed in upper-secondary schools in Norway and Russia, reported implementing, their beliefs about how multilingualism benefitted students and teachers, and their self-assessed ability to teach language aspects and skills. The study also investigated whether sociobiographical variables and participants’ language habits outside of work affected their beliefs about multilingualism benefitting their students and implementation of multilingual pedagogies. The findings revealed that participants utilized multilingual pedagogies least frequently when teaching in first language contexts and that those who used foreign languages outside of work applied such pedagogies more frequently than participants who did not. Moreover, their beliefs about multilingualism benefitting their students were positively predicted by their beliefs about multilingualism benefitting teachers and negatively predicted by their support of the monolingual approach to language learning and teaching.

Objectives

To investigate the risk factors for early recurrence after curative pancreatoduodenectomy for resectable pancreatic ductal adenocarcinoma.

Methods

All data were retrospectively collected from patients with resectable pancreatic ductal adenocarcinoma who had undergone pancreatoduodenectomy at the Department of Surgery, Phramongkutklao Hospital, from January 2015 to December 2020. The preoperative and perioperative risk factors were included into the analysis.

Results

In total, 34 patients were included in the study. The median time for recurrence and median survival time were 17 and 20 months, respectively. The 1, 3, and 5 year disease-free survival rates were 59.6%, 23.87%, and 23.87%, respectively, while the 1, 3, and 5 year overall survival rates were 81%, 24.7%, and 12.4%, respectively. Seventeen patients (50%) from a total of 34 patients had recurrence, and ten patients (29.41%) had recurrence within 12 months. The independent preoperative risk factor associated with adverse disease-free survival was tumor size > 4 cm (hazard ratio [HR], 14.34, p=0.022). The perioperative risk factors associated with adverse disease-free survival were pathological lymphovascular invasion (HR, 4.31; p=0.048) and non-hepatopancreatobiliary surgeon (HR, 5.9; p=0.022). Risk factors associated with poor overall survival were microscopical margin positive (R1) resection (HR, 3.68; p=0.019) and non-hepatopancreatobiliary surgeon (HR, 3.45; p=0.031).

Conclusions

Tumor size > 4 cm from the preoperative imaging study was a poor prognostic factor for early recurrence after curative pancreatoduodenectomy for resectable pancreatic adenocarcinoma indicated that they may have radiological occult metastasis, thus, staging laparoscopy may reduce the number of unnecessary laparotomies and avoid missing radiologically negative metastases.
Energy and Entropy in Open and Irreversible Chemical Reaction–Diffusion Systems with Asymptotic Stability
Authors: Ledesma-Durán Aldo , Santamaría-Holek Iván
Published: June 2022

This work proposes a novel approach for the study of open systems described by completely irreversible reaction mechanisms in non-homogeneous systems and subject to non-equilibrium boundary conditions. Using the non-equilibrium thermodynamics framework, we consider that in an autonomous system of reaction–diffusion equations, the thermodynamic potentials can be constructed from a Lyapunov function that depends directly on the eigenvalues and eigenvectors of the linearized problem. By interpreting this Lyapunov function as the free energy and redefining the chemical potentials, we were able to demonstrate the local stability properties of non-equilibrium stationary states, i. e., states that do not change with time due to a complex equilibration of internal and external flows. We demonstrate the consistency of our hypotheses with basic thermodynamic principles such as the spectral decomposition of entropy production and the Glansdorff–Prigogine evolution criterion. We discuss how our approach allows us to understand thermodynamic systems without assuming equilibrium or any kind of reversibility.

Published: June 2022

The purpose of this study is to investigate the contributions of public libraries to the satisfaction of the intellectual needs of rural inhabitants in West Bengal, India. The study applied a quantitative survey method with the help of a well-structured questionnaire. Questionnaires were distributed among to the users (students, officers/professionals, self-employed individuals, businessmen, jobseekers, retired persons, and housewives) of 45 rural public libraries in five selected districts of West Bengal. The study found that the largest group of respondents belonged to the students and jobseekers categories, who visit the rural public libraries for seeking academic and job-related information. Many students from humble backgrounds were solely dependent on public libraries because they have procured some textbooks from middle school up to graduation level. Jobseekers were mostly consulting the Career Guidance Section of the library to prepare for various competitive exams. The study also revealed that public libraries have been trying to satisfy the intellectual and informational needs of the rural inhabitants by providing various services and facilities. Respondents have further reported that public libraries should adopt modern technologies and provide ICT-based library services as well. The outcome of this study would help to develop and upgrade the public library collection, services, and facilities in developing countries in a way that reflects patrons’ stated needs.
The University Library’s Strategic Process: Competing Through Plans, Positions, and Resources
Authors: Edgar William B.
Published: June 2022

The traditional notion of university library strategy has been that of a pattern of goal-oriented activities that implement a strategic plan. Through conceptual analysis, this paper integrates strategic planning with two other perspectives—strategy based upon competitive position and upon library resources—to propose that a university library can best serve its academic community through a “strategic process” when supporting research and teaching. Drawing extensively upon applicable library science and strategic management literature, the paper presents the potential contribution of each perspective and of the entire strategic process using relevant examples. Successfully applying the strategic process enables university library managers to move forward with optimism in difficult competitive and financial situations. The process enables the university library to gain sustainable competitive advantage over its competitors by providing faculty and students with intellectual value in support of their discovery and education. As it operates, the strategic process empowers the university library to fulfill its traditional mission—providing persistent, generalized access to information—but to do so in transformed ways. The process also enhances library managers’ ability to communicate such successes to university decision-makers, illuminating the library’s effective use of scarce financial resources.

Published: June 2022

Recently, the monkeypox virus has begun to spread in many countries worldwide [1]. The genome sequence of the monkeypox virus variant responsible for the current outbreak has been reported, thus providing an important resource for better understanding the new variant and accelerating vaccine and drug development. Here, we report structure predictions of the whole proteomes of three monkeypox variants, with annotation of potential small-molecule-binding regions of the proteins. Experimentally determined structures with high similarity to monkeypox proteins were vetted through a structure-alignment algorithm. Our work should help accelerate the development of vaccines and drugs.

Authors: Bock Jiří
Published: June 2022

This study identifies in more detail the persons listed in the i nventory of tax list by finding the location of their houses and professions. It outlines the image of Liberec and the period atmosphere with a probe into the everyday life of the city‘s inhabitants and its topographical description. In August 1654, there were 249 residential houses and 18 buildings of a different nature, which sheltered approximately 1 900 inhabitants of 29 different professions. The city expanded to the south and west. The attic house with a half-timbered walls of the first floor was used in the construction of the town until the middle of the 18th century. The inhabitants of Liberec were divided into three categories – 63 burghers, homemakers and tenants. Most of the townspeople and other housekeepers, in addition to crafts, were engaged in agriculture. Craftsmen of various specializations and merchants served to satisfy the needs of the inhabitants. The influence of fashion introduced probably from southern Germany applied in men‘s clothing. Two baths were used for personal hygiene and health care. Import ant meeting places for the male population included 7–9 public taverns and three privileged inns. The life of the inhabitants of Liberec was influenced by the presence of the administrative apparatus of the Liberec estate.
