Authors: Touil Anass , Ayad Khalid , El Hamidi Nabil , Babounia Aziz
Published: December 2023

The green supply chain (GSC) has become essential for companies seeking to improve their environmental performance and meet the requirements of sustainable development. This concept is particularly relevant in an era of globalization and growing environmental awareness. The study used a Probit regression method to analyze data collected from Moroccan SMEs. It aimed to examine the impact of different factors, such as economic and energy efficiency, government incentives, stakeholder pressure, managerial age, company size, and profitability, on the adoption of GSC practices. The results showed that economic and energy efficiency, as well as stakeholder pressure, are significant factors positively influencing the adoption of GSCs. When combined with stakeholder pressure, government incentives also have a positive impact. The age of the executive has a negative influence on the adoption of GSC, indicating that younger executives are more likely to adopt these practices. Company size showed no significant impact, while profitability had a positive impact with the adoption of a GSC.

Authors: Fernández Fernández Eduardo , López García Ana Teresa , Gomez Gordillo Luis Angel
Published: December 2023

Este artículo analiza la estrategia de argumentación retórica empleada por la candidata Delfina Gómez en su campaña electoral para la gubernatura del Estado de México en 2023, a través de mensajes publicados en la plataforma de Twitter. El estudio se centra en el análisis cualitativo de seis tipos de argumentos: pragmáticos, morales, causales, de indicios, generalización y de autoridad. Algunos de los resultados revelan que la candidata implementó una efectiva estrategia de argumentación, en la cual destacó por su compromiso con la honestidad, la lucha contra la corrupción y la aplicación práctica de sus propuestas. Sin embargo, también utilizó la sobregeneralización y citas de una sola autoridad, al presidente López Obrador. Todos estos elementos le permitieron a la candidata diferenciarse de sus oponentes y finalmente obtener la victoria en las elecciones
Antioxidant, anti-inflammatory, antimicrobial, and anticancer properties of green broad bean pods (Vicia faba L.)
Authors: Elbadrawy Elsayed , Mostafa Mona Y.
Published: December 2023

This study featured broad/fava bean pods as by-products of food production. It assessed the chemical composition of green bean pods (Vicia faba L.) and their methanolic extract.
The extract was tested in vitro for antioxidant, anti-inflammatory, antimicrobial, and anticancer activities against prostate cancer (Pc3) and liver cancer (HepG2) cells. Broad bean pods proved to be rich in carbohydrates, fiber, protein, potassium, calcium, and magnesium. The extract contained 286 mg GAE/g total phenols and 105 mg QE/g total flavonoids. The antioxidant activity of the methanolic extract was measured by 1,1-diphenyl-2-picryl hydrazyl (DPPH) assay. The highest DPPH scavenging activity belonged to the extract concentrations of 1000 μg/mL (80.5%) and 500 μg/mL (73.7%), whereas the IC50 value was 87.35 μg/mL. The methanolic extract possessed the anti-inflammatory effect as it significantly reduced the hemolysis of red blood cells. The maximal inhibition percentage reached 66.7% at 1000 μg/mL. Regarding the antimicrobial activity, the broad bean pod methanolic extract inhibited Bacillus subtilis, Staphylococcus aureus, Escherichia coli, and Pseudomonas aeruginosa, as well as Candida albicans. The extract reduced the cell viability of human hepatocarcinoma (HepG2) and prostate cancer (PC3) cells in a concentration-dependent manner. It also caused significant changes in cell shape, compared to the control.
Therefore, broad beans can be recommended for human consumption together with pods, fresh or cooked, as a potential source of bioactive substances in functional food production.
Rayleigh waves in an electroelastic medium with prestressed inhomogeneous coating

Published: December 2023

An approach to studying the influence of initial mechanical stresses and an electrostatic field on the structure and behavior of Rayleigh waves in piezoelectric media with non-homogeneous coatings is proposed. The paper considers two-component coatings made of functionally graded piezoelectric material with high-speed or low-speed inclusions. The initially deformed state of the coating is induced by the separate or combined action of initial mechanical stresses and an external electrostatic field. The influence of the type of non-homogeneity and the nature of initial mechanical stresses in the presence or absence of an initial electrostatic field on the features of Rayleigh wave propagation for problems with an electrically open or shorted surface is studied. It is established that the presence of a low-intensity initial electrostatic field only slightly affects the action of initial mechanical stresses depending on its direction. The presence of a high-intensity electrostatic field leads to additional deformation of the material, significant changes in the speeds of PAV modes, and substantial changes in the structure of the surface wave field. The obtained results are presented in dimensionless parameters and may be of practical interest in the development, design, and optimization of new materials for micro- and nanoscale devices and devices on Rayleigh surface acoustic waves with high performance characteristics.

This article is the second part of the work devoted to the investigation of the nonlinear dynamics of parametrically excited flexural vibrations of a clamped-clamped microbeam - the basic sensitive element of a promising class of microsensors of various physical quantities - under laser thermooptical action in the form of periodically generated pulses acting on a certain part of the surface of the beam element. The fundamental technical feasibility of laser generation of parametric oscillations of high-Q microresonators without the implementation of scenarios for the loss of elastic stability of the sensitive element or its unacceptable heating is shown. The nature of the zone of the main parametric resonance is analyzed analytically. The resonant characteristics of the system are constructed in a geometrically non-linear formulation corresponding to the Bernoulli - Euler beam model.

Published: December 2023

Generation algorithms of record times and values obtained from sequences of independent and non-identically distributed random variables which distribution functions are defined on a common support are proposed in the present paper. Known algorithms of generation of record times and values are given in introduction for the case when the initial random variables are independent and identically distributed. The brief review of scientific literature associated with this topic is also given in Introduction. It is also pointed out there that all efficient algorithms of record generation are based on the Markov property of records. In Section 2 the distribution functions of record times and values are derived for the case when the initial random variables are independent and non-identically distributed. The corresponding record generation algorithms are for the first time proposed. These algorithms are based on the derived distributions and the Markov property of records that also holds in the case when the initial observations are independent but non-identically distributed. In the end of this work in Section 3 the proposed algorithms are tested by simulation experiments. In these experiments the records are generated for the case when the initial random variables have the Gumbel distribution functions​
Conditions of local parameter identifiability for systems of differential equations with an infinite-dimensional parameter
Authors:   St. Petersburg State University, Pilyugin Sergei Yu. , Shalgin Vladimir S. ,   St. Petersburg State University
Published: December 2023

The problem of parameter identification (determining parameters of a system by observing solutions or functions of them) is one of the main problems of the applied theory of differential equations. The property of local identifiability plays the most important role in solving this problem. The presence of this property means that one can uniquely determine values of parameters of a system in a neighborhood of a particular parameter by observing solutions. Earlier the case of a finite-dimensional parameter was mostly studied in this issue. The problem of local parameter identifiability in the case of an infinite-dimensional parameter is less studied. In this paper we propose a new method for obtaining sufficient conditions for local parameter identifiability in the case of an infinite-dimensional parameter. Under these conditions an infinite-dimensional parameter belonging to certain classes is locally identifiable by observing a solution at a finite set of points. For system with linear dependence on a parameter we establish the genericity of the mentioned conditions.
On asymptotic behaviour for probabilities of moderate deviations of combinatorial sums
Authors:   St. Petersburg State University, Frolov Andrei N.
Published: December 2023

We investigate an asymptotic behaviour for probabilities of moderate deviations of combinatorial sums of independent random variables having moments of order p > 2. We find zones in which these probabilities are equivalent to the tail of the standard normal law. The width of the zone is a function from the logarithm of a combinatorial variant for Lyapunov’s ratio. The author earlier obtained similar results under Bernstein’s and Linnik’s conditions. The truncations method is used in proofs of the results.
Application of hybrid Riemann solvers based on HLLC and HLL for simulation of flows with gas-dynamic discontinuities
Authors:   Khristianovich Institute of Theoretical and Applied Mechanics of the Siberian Branch of the Russian Academy of Sciences, Shoev Georgy V.
Published: December 2023

Application of hybrid approximate Riemannian solvers based on standard HLLC and HLL solvers is discussed. Three different hybrid solvers are considered. The first hybrid solver (rHLLC-HLL) uses a weighted sum of HLLC and HLL so that HLLC is applied in the direction normal to the shock wave while HLL is applied in the direction along it. The second hybrid solver (HLLC-ADC) uses the weighted sum of HLLC and HLL, applying as weights the pressure function at the left and right cell centers. The third hybrid solver (HLLC-HLL) computes inviscid fluxes by HLL inside shock waves, and by HLLC in other areas of the flow. Facets within shock waves are defined by a shock wave indicator based on the reconstructed left and right pressure values of the face. Several tests are performed, and it is shown that hybrid solvers prevent the carbuncle and reduce oscillations on shock waves.
Induction: Possibilities, frequency, and confidence
Authors:   Institute of Humanistic Studies, Research Center on Cognitive Sciences, University of Talca, Talca Campus (Chile), López-Astorga Miguel
Published: December 2023

The theory of mental models describes how human beings often make inductive inferences. That account is based on possibilities. It claims that, in inductions, people tend to prefer the possibility that seems to be more probable. The present paper tries to develop the account by proposing an additional quantitative method to determine which of the two possibilities in inductive processes is preferable. The paper resorts to a Non-Axiomatic Logic: NAL. NAL assigns quantitative values to the frequency and confidence of sentences. It also shows how those values can be transmitted from premises to conclusions in inductive inferences. This part of NAL is applied to the account of induction the theory of mental models gives.
The Ethics of (Non)disclosure: Large Language Models in Professional, Nonacademic Writing Contexts
Authors:   Nicholls State University, 906 E. 1st St., Thibodaux, LA 70301, United States of America, Piller Erick
Published: December 2023

This article explores the ethics of co-writing with large language models such as GPT-4 in professional, non-academic writing contexts without disclosing the practice to stakeholders. It considers five ethical concepts through an analysis of a hypothetical scenario. Three of the concepts—transparency, data practices, and expanded circulation—originate in the work of Heidi McKee and James Porter. The other two, just price and risk imposition, have particular relevance for professional writers. The article ultimately proposes that these five concepts can serve as points of reference as we attempt to formulate and articulate ethical judgments about co-writing with generative AI in specific, contextually grounded instances.
“I Am Not Just a Man”: Chinese Butterfly’s Identity Anxiety and Ethical Predicament in David Henry Hwang’s M. Butterfly
Authors:   School of Foreign Languages, Hunan University, Changsha, China., Tao Shilong , Chen Xi
Published: December 2023

M. Butterfly is narrated through the memory of Western white man Rene Gallimard, which makes the audience focus on Gallimard’s behaviors and ignore the Oriental man Song Liling’s emotions, actions, and choices. However, there are many plots portraying Song as a Chinese Butterfly to deconstruct the stereotype of Madame Butterfly. This paper, from the perspective of ethical literary criticism, probes into Song’s brain texts formed in their growth and working experience and analyzes Song’s anxiety and confusion about his multiple and chaotic ethical identities, so as to demonstrate that Song is not a “dragon lady” or a “transvestite”. In China, Song is feminized and marginalized in society as “a son of a prostitute”, “a gay”, and “an Opera actor”. He wants to change the situation, so he becomes “a spy” for the Chinese government and “a lover” for Gallimard. Still, due to the failure of ethical enlightenment in childhood and the cruel social environment in China, Song is trapped in ethical predicaments of “to be or not to be”, struggling in the ethical conflicts between the honor of the individual and the interest of the nation, as well as between the desire for love and the mission from government. The song is a victim of the era and politics, and his identity anxiety and ethical predicament reflect David Henry Hwang’s position as an Asian American playwright and reveal his ethical appeal for gender equality, identity recognition and cultural confidence.
Dismantling France’s Manhood in the Prose Works of Holinshed and Sidney
Authors:   Qatar University, Al-Mutawa Abdulaziz
Published: December 2023

The socio-political dimension of the word ‘manhood’ is undoubtedly an indication of the superiority and advancement of the English over the rest of the neighboring countries, in particular France. These prose works define what nationalism is. Furthermore, it was also an indication that reflects the pride and supremacy of England and its citizens. This research aims to explore how the Elizabethans, through these two works, dealt with France and how manhood is deployed in their perspective, and how it is relevant to several epithets such as valor and courage. This study conducted a content analysis with the help of the excerpts from the two literary texts. The study concluded that in both literary works, the authors had shown religious and political bigotry and showed the influence of the Elizabethans. It depicted that Elizabethans were superior in having manhood as compared to the Frenchmen.
Textual Alchemy: AI, Authorship and the Shifting Paradigms of Interpretation
Authors:   North Campus, University of Kashmir., Hussain Adil , Qazi Khursheed Ahmad
Published: December 2023

Artificial intelligence is overhauling the publication and textual production. Textual production with Large Language Models (LLMs) is more sophisticated and closer to human knowledge production thanks to its autoregressive nature. AI models by OpenAI such as the Generative Pre-trained Transformer 3 (GPT-3) and its iterations use deep learning to produce more human-like text. Such texts invite all kinds of problems that are not new to the human text-production system. Research shows that the output of such models tends to be biased toward a particular gender, race and ethnicity. This paper explores substantial texts produced by AI including articles, fiction, columns, opinion pieces etc. published in major journals and magazines to understand the nuances of such texts. Moreover, the paper will attempt to understand such features of AI-generated text by presenting the results of a particular set of instructions (prompt) to the LLM. These text outputs will be studied to demonstrate how AI-generated texts pave the way for a “post-post author” era, echoing Barthes’ notion of the “Death of the Author”. The scope, usability and limitations of the AI’s textual production will also be investigated.
Artificial Intelligence (AF) in Human Fantasy: The Birth of a New Subject in Kazuo Ishiguro’s Klara and the Sun
Authors:   Department of English, University of Asia Pacific., Akter Sharifa , Islam Niger Afroz
Published: December 2023

In Klara and the Sun (2021), the Nobel Prize-winning Japanese-British writer Kazuo Ishiguro fantasizes about an unspecified future world of possibilities for life with Artificial Intelligence. This novel raises complex questions about the notion of intelligent life, the fantasy of transcending the limits of nature, the future of the social bond, and the constitution of human emotions. This study portrays the unconscious fears, fantasies, and fascination created in the novel’s plot, centred on the solar-powered AF (Artificial Friend). The novelty of this paper is to show how Klara, the Artificial Friend, the humanoid, traverses the Imaginary, Symbolic, and Real and becomes a new Lacanian subject. The careful explanation of the study attempts to chart the impact of a new subject on human fantasy in society and culture from Zizek’s concept of Ideological Fantasy. It explores how subjects lose their internal being when their lives are entirely commodified and exploited as a component of capitalism. Finally, Ishiguro ends his novel where the being (nature) owns over the thing (commodity). This paper will also attempt to enlist the impact of dystopian fiction on society and culture. Hence, in conclusion, this study explores a constructive approach to understanding human fantasy and acknowledges the text as a scope that meets interdisciplinary promises.
Patient’s Consent and Autonomy in Jerry Pinto’s Em and the Big Hoom
Authors:   School of Humanities and Social Sciences, Indian Institute of Technology, Indore, India. *Corresponding author., Tiwari Nimisha , Das Aratrika
Published: December 2023

This paper addresses the idea of patient consent in the Indian mental health care system. Mental hospitals tend to treat patients as machines. The personhood of the sufferer is treated as invalid. The paper argues that the conventional clinical practice dehumanizes patients, neglecting their autonomy and perpetuating the stigma associated with a psychiatric diagnosis. In contrast, through the narrative voice of Imelda’s son, Jerry Pinto’s novel Em and the Big Hoom (2012) intimately intertwines the experiences of mental illness within the broader context of familial struggles. Em refuses to become a mere statistic or a diagnostic label, embodying the agency to shape her narrative beyond the constraints of clinical definitions. The novel challenges the flawed clinical gaze and provides an alternative narrative that portrays an ambitious woman who does not succumb to the definitions of her illness. These alternative narratives resist reductionist perspectives, offering a more comprehensive understanding of mental illness that transcends clinical definitions. This paper critically examines the novel’s portrayal of patient autonomy and consent, shedding light on the implications for mental health care practices in India. It explores how the text serves as a catalyst for reevaluating conventional clinical perspectives and fosters a more compassionate and patient-centric mental health care system.
From Third Space to Transnational: A Study of Alter Identities in Bharati Mukherjee’s Jasmine
Authors:   Mahatma Gandhi University, Prakash Athira
Published: December 2023

The burgeoning presence of the Indian Diaspora across the world has triggered a new consideration of the cultural theories of nation, identity and international affairs. Depicting the process of negotiating the borders, both physical borders of states and countries and the metaphorical borders, between genders generations and cultures, Bharati Mukherjee, an American writer of Indian origin, raises the question of space and identity of the Indian immigrants in the US. An attempt is made to map the journey of the Indian Diaspora from the status of the immigrants to that of the transnational citizens of the world. The scope of this study lies in its treatment of transnational space which is going to redefine the idea of Diaspora as a process of gain, contrary to conventional perspectives that construe immigration and displacement as a condition of terminal loss and dispossession, involving the erasure of history and the dissolution of an “original” culture. Rejecting the binaries of the Western Centre and the Eastern Periphery, the paper invites a post-structural approach to the cultural identity construction of the Indian Diaspora.
Identity versus Identity Crisis: An Analysis of Erikson’s Epigenetic Principle in Isabel Allende’s Daughter of Fortune
Authors:   Sri Sarada College for Women (Autonomous), Salem. Tamil Nadu. India., Sarojini P.
Published: December 2023

Identity and identity crisis are crucial aspects of a person’s mental and physical well-being. Identity is what sets an individual apart from others in society. An identity crisis can cause a person to experience confusion and uncertainty at various stages of their life. Erikson’s Theory of Psychosocial Development is based on the ‘Epigenetic principle,’ which suggests that our environment and culture influence how we progress through the planned stages of personality development. Erikson’s eight stages describe how people develop emotionally and socially throughout their lifespan. In Isabel Allende’s novel, Daughter of Fortune, the protagonist Eliza Sommers undergoes an identity crisis. The paper focuses on this concept of identity and identity crisis and the mystery and troubled identity surrounding Eliza Sommers.
Optimist vs Pessimist: Indulging and Contextualizing Martin Seligman’s Learned Optimism in “Once Again” and “Trisanku” by C.S. Lakshmi
Authors:   PG & Research Department of English, Sri Sarada College for Women (Autonomous), Salem, Tamil Nadu, India., Priya M. Aarthi
Published: December 2023

Martin Seligman, the founder of positive psychology, developed the idea of ‘learned optimism’ by embracing the idea that an optimistic outlook can be developed through learning. This article discusses the idea of learned optimism, its advantages, and how one may begin to transform their life and thinking. According to the analysis, optimistic personalities appear to have a greater success rate when it comes to reaching their intended goals, even when the pessimistic characters do amazing things in their lives. Both pessimists and optimists achieve things in their lives, but optimists are perceived as having accomplished more. Martin Seligman’s theory of learned optimism is analysed and contextualized in this paper, which aims to evaluate the optimistic and pessimistic personalities found in the characters in the selected short stories of C.S. Lakshmi. Seligman’s concept of learned optimism is well connected with the characters of Loki in “Once Again” and Anjana in “Trisanku”. The characters are also subjected to cognitive distortions of the three P’s: Personal, Pervasive and Permanent to develop themselves to be optimistic personalities through the concept of learned optimism. Seligman also proved that through learned optimism one can change from a pessimistic to an optimistic personality so that they can prevent themselves from depression and anxiety.
Colonialism, Diasporic Politics and Alternate History in Shauna Singh Baldwin’s What the Body Remembers and Anita Rau Badami’s Can You Hear the Nightbird Call?
Authors:   UILAH, Chandigarh University, Mohali, Punjab., Bansal Tania
Published: December 2023

Shauna Singh Baldwin in her novel What the Body Remembers (1999) and Anita Rau Badami in Can You Hear the Nightbird Call? (2006) take up diverse treatises which are advantageous in the construction of subjectivity of a postcolonial subject. The present article deals with Baldwin’s representation of the nation and Badami’s depiction of politics, which trespass borders and affect diaspora Sikhs and members of other communities. Colonialism has been one of the causes of communalism which resulted in distortions in the historical representations of the events. Both the novelists amidst religious and historical landscapes of India also make political statements in their distinctive ways. It is interesting to analyze these statements from the perspective of postcolonial discourse as both authors belong to a period when literary texts and histories are being re-examined with a counter-narrativistic assessment. Both the authors bring out the Sikh perspective on the colonial and racist policies of the British in India and the colonial/postcolonial racist attitude of majority communities in foreign lands towards ethnic minorities through the characters taken in the novels under study. Politics of extremism and fundamentalism is the crux of both the novels. The English language has been shown to have been given a special status in the colonial regime. How language becomes a tool of both subversion and oppression is an important theme in both novels. The novels interrogate written history from alternate perspectives through the turmoil of time and space in which the novels are written. Both Badami and Baldwin conceive their characters presenting them as products of their time, place and environment.
A review on sources of uncertainties for groundwater recharge estimates: insight into data scarce tropical, arid, and semiarid regions
Authors: Beyene Tsegamlak Diriba , Zimale Fasikaw Atanaw , Gebrekristos Sirak Tekleab
Published: December 2023

Successful sustainable groundwater management requires accurate information on recharge for a given aquifer system. However, recharge estimates are usually used in relative terms rather than an absolute sense. A review of available studies on groundwater recharge estimate uncertainty as well as tools for uncertainty analysis was conducted. Nonetheless, except for the handful of studies that have conducted proper uncertainty analysis, most were inclined to implement multiple methods as an indication of the range of uncertainty. The global trend indicates that considering the significant number of methods for recharge estimation, very little has been done to assess the uncertainty of each method. Therefore, more attention should be given to the individual uncertainty analysis of selected methods as much as using multiple methods recommended for investigating uncertainty. Insight from the review indicates that, when used carefully, tracer-based analysis can be effective and coupling is required for uncertainty analysis. Furthermore, spatial uncertainty due to input data could potentially be minimized by using input data from multiple sources. Better conceptualization of the hydrogeological process can reduce the uncertainty of numerical modelling. This review is limited to widely used methods and excludes uncertainty due to inappropriate method implementation and controlled experimental uncertainties.
A novel measure for long-term sediment reduction inspired by dragonfly wings
Authors: Li Zhiwei , Wang Bing , Wang Feifei , Sun Bin , Zhao Shuaikang
Published: December 2023

The sediment accumulation in drainage pipes has long been recognized as a significant concern in the environmental field. This study addresses sediment accumulation in drainage pipes by introducing an innovative bioinspired approach using various shapes and angles of plates for long-term sediment reduction. Through experiments and numerical simulations, the velocity field, the turbulent kinetic energy, the head loss, and the dynamic pressure distribution in the pipeline with plates are analyzed. Results demonstrate significant increases in local velocity, dynamic pressure, and turbulence energy due to the presence of plates. The sediment reduction performance shows a positive correlation with the angle for folded plates and a non-linear relation with curvature for curved plates. Notably, the superior performance of folded plates is attributed to their exceptional ability to induce vortex formation. The head loss due to sediment reduction measures increases linearly as the angle and the curvature increase. Furthermore, the intentional induction of strong eddies and high shear flow using the undulating topography created by the locally installed folding plates in the pipeline was the main cause of sediment reduction. This novel approach holds promise for more efficient and sustainable sediment reduction in drainage systems.

Published: December 2023

Introduction: Despite the advancement interventional methods for treating atrial fibrillation, the effectiveness of catheter ablation remains poor, especially in patients with persistent and long-persistent atrial fibrillation. Thus, experts continue to explore new treatments for this arrhythmia. The issue of experimental studies investigating the association between spinal cord stimulation and atrial fibrillation is mainly attributed to the lack of optimal algorithms for spinal cord stimulation in animal experiments. Therefore, it is important to develop adequate algorithms for spinal cord stimulation in the chronic model of atrial fibrillation.Objective: To evaluate the impact of spinal cord stimulation on the model of atrial fibrillation in mini-pigs.Methods: In a series of experiments, 6 (100%) successful implantations of electrodes and pacemakers, and spinal cord stimulation electrodes were performed. The electrodes were used to stimulate the atria, creating a model of atrial fibrillation, while the spinal cord stimulation was carried out using an electrode implanted into the spinal canal. During the experiment, an electrophysiological study was performed using an implanted pacemaker. The inducibility of atrial fibrillation was assessed before and after the experiment using various spinal cord stimulation algorithms.Results: There were no complications associated with surgery or stimulation of the atria and spinal cord. Spinal stimulation had a modeling effect on the autonomic nervous system, significantly changing the average heart rate, Wenckebach point, and effective refractory period. When comparing spinal stimulation algorithms, algorithm 1 was found to significantly reduce the atrial fibrillation inducibility.Conclusion: Spinal cord stimulation had a modeling effect on the autonomic nervous system, significantly changing the average heart rate, Wenckebach point, and effective refractory period. Inducibility of atrial fibrillation decreases with changes in the spinal pacing algorithm.

Objective: To evaluate the effect of CYP2C19 gene polymorphisms on clinical outcomes in patients after successful revascularization for acute myocardial infarction with and without ST segment elevation during clopidogrel therapy for 60 months of follow-up.Methods: From 2011 to 2012, 363 patients with acute myocardial infarction who underwent coronary revascularization were included in the study. In the postoperative period, the patients underwent genetic analysis for the CYP2C19 gene polymorphism. All patients received dual antiplatelet therapy with aspirin and clopidogrel. The 60-month follow-up period assessed the primary composite endpoint of the cumulative incidence of all-cause mortality, recurrent myocardial infarction, and stroke.Results: At 60 months after the initial intervention, 71 patients had a composite primary endpoint event (all-cause death, recurrent myocardial infarction, or stroke): 50 (20%, 95% CI 16–25) in the group patients with "wild genotype" and 21 patients of the "loss of function (LOF) *2+*3" group (19%, 95% CI 13–27). No significant relationship was observe between carriage of LOF alleles of the CYP2C19 and the primary endpoint during the 60-month follow-up (HR 0.99, 95% CI 0.59–1.65, P = .965), as well as between carriage of the homozygous CYP2C19 variant (*2/*2) and the development of myocardial infarction during the same period (HR 1.26, 95% CI 0.30–5.20, P = .752).Conclusion: No correlation was observed between the CYP2C19 gene polymorphisms (*2, *3 alleles) and the incidence of ischemic events in patients with myocardial infarction after myocardial revascularization throughout a 60-month follow-up period.

Mitral allografts in tricuspid valve position in modern surgery of acquired heart defects: a systematic review
Authors: Skopin I.I. , Latyshev M.S. , Britikov D.V.
Published: December 2023

Introduction: In severe recurrent infectious lesions in the right heart, one of the alternative options for bioprosthetics is to implant mitral allografts (donor heart valves) in the tricuspid valve position. Allografts offer numerous benefits, including a configuration that closely resembles a native valve, adaptability to high systemic pressure, absence of foreign elements that can could act as entry points for infections, and antibacterial treatment without lifelong anticoagulant therapy.Objective: To study the feasibility of using a mitral allograft in the tricuspid position based on the analysis of literature data and our own experience.Methods: Searches were conducted in Medline (PubMed), Google Scholar, and Russian Science Citation Index databases using search queries, keywords, and logical operators. The last session was conducted on December 21, 2022. In the initial selection of aforementioned search queries, a total of 4,446 results were obtained (Google Scholar — 3,080, Medline — 1,050, Russian Science Citation Index — 316).

Fe y Sociedad: Valoración teológica de la modernidad y la ilustración en Joseph Ratzinger
Authors: Soler Carlos
Published: December 2023

El cristianismo estuvo enfrentado con la modernidad y la ilustración durante siglos. En el siglo XX la teología católica buscó una reconciliación, que dio frutos en el Vaticano II. Aquí estudiamos la opinión de Ratzinger sobre la relación del cristianismo con la modernidad y la ilustración. Al respecto establecemos tres etapas en su carrera académica: 1ª) desde 1951 a 1967 sienta las bases teológicas, pero no aborda temáticamente la cuestión; 2ª) a partir de 1967 establece que el cristianismo puede y debe asumir las reivindicaciones sustanciales de la modernidad y la ilustración, pues pertenecen a la esencia de la fe cristiana; al mismo tiempo, critica con fuerza algunos aspectos concretos de una y otra; 3ª) desde 1990 da una ulterior profundidad a la tesis sobre la aceptación sustancial de la ilustración. La aportación principal de Ratzinger es la siguiente: el papel que la razón tiene en la fe, aspecto central de su teología, lleva a la concordia del cristianismo con las reividicaciones intelectuales de la ilustración; razón y fe se purifican y se iluminan mutuamente. Aquí nos centramos en la aceptación, y al final exponemos las críticas de modo más breve.

Background:

Ratoon rice production is one of the rice cultivation technologies with the potential to reduce labor and increase yield rate under a shorter cultivation time. However, few studies have focused on the effects of different water management on grain yield and quality.

Objective:

The aim of this study was to explore the effects of different water management on grain yield and quality in ratoon rice.

Methods:

Three water management treatments were followed- Control with the water level 5 cm aboveground, underground water treatment (UWT) with the water level 12 cm below the soil surface, and deep water treatment (DWT) with the water level 20 cm aboveground. The grain yield, yield components, amylose and protein content, and grain characteristics for grain quality were measured.

Results:

During the ratoon season, UWT had the highest grain yield of the three treatments. DWT had the highest ratoon tiller number but had a lower grain yield due to the increase in the number of ratoon tillers. The 1000-grain weight decreased markedly for DWT. With respect to grain quality, ratoon rice has a higher amylose content and a lower protein content than the main crop rice. UWT had the lowest protein content in the ratoon period and a higher grain yield.

Conclusion:

Yield performance in UWT is considered optimal for ratoon rice cultivation. However, grain quality under different water management did not show remarkable results. Therefore, the practice of fertilization during cultivation is recommended to improve grain quality.

This research explores the intricate dynamics between product quality, digital marketing strategies, and Small and Medium Enterprises (SMEs) performance. The study focuses on the entire population of 43 SMEs affiliated with the Representative Office of Bank Indonesia in South Sumatra Province in 2022. These SMEs benefit from comprehensive guidance provided by Bank Indonesia consultants and actively participate in mentoring programs spanning both conventional and Sharia SME schemes, reflecting a census-based sample selection. The findings derived from multiple linear regression analysis underscore a noteworthy positive and significant impact of product quality and digital marketing on SME performance. In a marketplace saturated with similar products in South Sumatra Province, SMEs must cultivate distinctive attributes that resonate with the local community, thus enhancing their competitive edge. Additionally, the geographical remoteness of SMEs from the city center emerges as a pivotal factor influencing their performance. This remoteness not only affects production logistics but also poses challenges to sales, thereby shaping the overall performance landscape of these enterprises. In essence, this research contributes valuable insights into the multifaceted relationship between product quality, digital marketing strategies, and the performance of SMEs, particularly those aligned with Bank Indonesia in South Sumatra Province.

Published: December 2023

Relevance. The study is connected with the need for a theoretical, methodological and empirical justification for the existence of unified normative-typical methods and forms of response, in the form of coping strategies that are routinely used by a person in a situation of confrontation with stress, and serve as a way to regulate any conflict situations.The purpose . To analyze the connection between the dominant coping strategy of the individual and the way of conflict regulation.Objectives. Explore the dominant coping strategies of respondents and the features of response and conflict resolution; reveal the existence of a connection between dominant coping strategies and methods of conflict management.Methodology The research methodology is based on the principles of consciousness and activity, the principle of determinism, the principle of the activity of the subject, the cultural and historical concept of L.S. Vygotsky, as well as on personality-oriented approaches to the study of individual strategies, styles and methods of coping behavior and conflict resolution of the individual.Results. A direct correlation was found between the strategy of overcoming stressful situations "Confrontation" and the method of conflict regulation "Competition" and inversely proportional relationship between the parameters "Confrontation" and "Cooperation". Direct correlation between the strategy of overcoming stressful situations "Distancing" and the method of conflict regulation "Avoidance" and inversely proportional relationship between the parameters "Distance" and "Cooperation". Direct correlation between the strategy of coping with stressful situations "Search for social support" and such methods of conflict regulation as "Cooperation" and "Compromise". Direct correlation between the strategy of coping with stressful situations "Escape-Avoidance" and such methods of conflict regulation as "Avoidance" and "Adaptation". Direct weak correlation was found between the strategy of coping with stressful situations "Positive reassessment" and the method of conflict regulation "Adaptation".Conclusion. There are basic behavioral constructs that determine the strategies of a person's behavior when faced with stress and (or) a conflict situation, which are normative-typical forms of emotional, behavioral and cognitive response, which are standardly used by a person in a situation with stress factors, and in any conflict situation.
