The role of board gender diversity and independence on the existence of a sustainability committee
Authors: Eryılmaz Mehmet , Martinez-Ferrero Jennifer , Colakoglu Nese
Published: January 2024

The purpose of this study was to enhance the understanding of the factors determining the existence of a “Corporate Social Responsibility” (CSR) committee on the board. Focusing the attention on board composition, this paper explores how female directors influence the existence of a CSR committee, and how this effect can be moderated by the independence of board members. To be able to test the aims of the study, an international sample of analysis of 4,168 firm-year observations from 2012 to 2016 was used, proposing several models for panel data. The findings revealed that female directors exert a positive influence on the existence of a CSR committee, although this commitment is limited when in addition to women, they are independent directors on the board. Therefore, it can be said that board gender diversity and board independence are not complementary mechanisms that favour the existence of a specific committee on CSR. This study is one of a limited number of studies to focus on the antecedents of existence of a CSR committee in firms. In addition, the study obtains benefit by considering the independence of board of directors as a moderating variable on the relationship female directors-sustainability. In contrast with previous studies based on the cross-sectional data from a single country, the data set of the current study includes a panel data comprising of a period between 2012 and 2016 and an international sample from 44 countries in six continents.

Феномен доверия к себе в человекоцентрированном подходе К. Роджерса
Authors: Бабанов Алексей Вячеславович
Published: January 2024

В статье проанализированы понятие и модель доверия к себе Т. П. Скрипкиной. Отталкиваясь от этого анализа, автор интерпретирует феномен доверия к себе в человекоцентрированном подходе и персонологии Е. Б. Старовойтенко. Для человекоцентрированного подхода К. Роджерса доверие к себе есть опора на свой организмический ценностный процесс. Личность может находиться в состоянии противоречия, когда представления о себе (Я-концепция) оказываются важнее и безопаснее для осознания, чем непосредственный организмический опыт. В таком случае потребности и ценности «Я» могут заблокировать организмический процесс ценения, отделить человека от собственной жизненной основы.

Решение данного практического противоречия состоит в изменении Я-концепции, в приведении ее в соответствие с организмическим ценностным процессом, т. е. в обретении человеком своей целостности. В персонологической модели рефлексивного отношения личности к себе «Я» понимается как субъект рефлексии, в процессе которой «Я» обнаруживает, что себя не знает. Есть «Я-неизвестное», в котором и заключено противоречие доверия к себе: как личность может чувствовать самоценность и надежность внутреннего опыта самой себя, если она мультисубъектна — если есть части ее, которые она не знает и которые недоступны для осознания.

Решение противоречия тоже практическое: оно заключается в интеграции, в достижении личностью своей целостности. Однако эти целостности имеют разные философские основания — различные идеи субъектности. В человекоцентрированном подходе субъектность человека — это целостность организмического процесса, сознания и гибкой Я-концепции, что говорит об идеи процессуальности личности, а в персонологической модели — целостность субъекта рефлексии (Я-известного и Я-неизвестного), что говорит об идеи субстанциальности личности. Процессуальность субъектности в холистическом подходе К. Роджерса была нами подсвечена с помощью идеи интуиции А. Бергсона.
The predicting value of circular DNA particles of T- and B-cell receptors for the dismal acute period outcomes and the disease severity of COVID-19 infection

Published: January 2024

The pandemic of the new coronavirus infection COVID-19, caused by the SARS-CoV-2 virus, continues to be a serious problem for the entire global community. Currently, most patients experience mild COVID-19, with only about 20% of those infected requiring hospitalization. The severe course of COVID-19 is most often associated with damage to the patient’s bronchopulmonary system by the virus and serious abnormalities, including damage to the air-hematological barrier, systemic inflammation, dysfunction of the immune system and the addition of secondary infections. Severe disease and poor outcome in hospitalized patients with COVID-19 may be associated with lymphopenia in combination with neutrophilia. Restoring the number of lymphocytes is important to improve the prognosis of the patient’s outcome. Patients with COVID-19 experience an immune imbalance where systemic inflammation and dysfunction of circulating T and B cells lead to more severe disease. TREC/KREC analysis can characterize the function of the central organs of the immune system and its relationship with clinical and laboratory data. Decreased TREC/KREC levels were observed in patients with unfavorable disease outcomes compared to patients with favorable disease outcomes. Additionally, a higher neutrophil to lymphocyte ratio was found. Levels of TREC and KREC in the blood negatively correlate with the neutrophil-lymphocyte ratio. Thus, the TREC/KREC assay is a potential prognostic marker for assessing the severity and outcome of COVID-19.

Published: January 2024

Hyperinflammation and dysfunction of the immune response during COVID-19 infection develops due to the reaction of innate immune cells to the introduction of the SARS-CoV-2 virus. The expression of receptors on these cells reflects the degree of their activation and makes it possible to assess the intensity of inflammation. The purpose of this study were to study the structural and functional features of innate immunity cells in patients. The specific gravity and absolute content of neutrophils (CD11b+, CD16+, CD18+) and monocytes (CD14+CD16–, CD14–CD16+, CD11b+, CD18+) in the peripheral blood of patients were determined. The contingent of the study included 60 people, of which: 47 had had a coronavirus infection COVID-19 (confirmed by PCR) in the 12 weeks preceding the study, and 13 had no history of it. In the peripheral blood of people who had COVID-19, compared with those who had not been ill, a significantly lower number of monocytes of the classical (CD14–CD16+) and, on the contrary, a greater number of non-classical (CD14+CD16–) cell populations were determined (p0.05). Also in these individuals, a high proportion of monocytes carrying the adhesion receptors CD11b and CD18 (p0.01) and a high content of neutrophils expressing the adhesion receptor CD11b+ and CD16+ (p0.05) was noted. Thus, the results of a study of the expression of various types of receptors on monocytes and neutrophils illustrated the long-term preservation of aberrant structural and functional characteristics of innate immunity cells in individuals who underwent COVID-19.
The effect of post-covid syndrome on the cytokine cascade in patients with type 2 diabetes mellitus

Published: January 2024

With the increasing prevalence of type 2 diabetes, it is of interest to study the characteristics of the immunological status in this category of patients. According to modern data, in type 2 diabetes, a pro-inflammatory type of immune response is formed with an imbalance between T-helper 1 (Th1), T-helper 2 (Th2), T-helper 17 (Th17) types and T-regulatory cells (Treg). The COVID-19 pandemic makes a certain contribution to changes in the immune response in patients with type 2 diabetes mellitus, since in patients who have had coronavirus infection, significant changes in the composition of circulating immune cells are observed: the proportion of Th17 increases and the number of Tregs decreases. This study is devoted to identifying the features of the cytokine cascade in patients with type 2 diabetes mellitus, depending on the presence of a confirmed history of SARS-CoV-2 infection. The study included 75 patients with type 2 diabetes, in 36 of them the diagnosis was verified in the post-Covid period. The study was conducted at least 6 months after pneumonia caused by SARS-CoV-2 infection. All study participants signed informed consent. The study was approved by the Independent Local Ethics Committee at the State Autonomous Institution of Regional Clinical Hospital “City Clinical Hospital No. 1” of Chelyabinsk, protocol No. 8 dated 04/11/2022, on the basis of which these studies were conducted. Using the multiplex assessment method, the concentrations of 15 cytokines in the blood serum were assessed in patients: GM-CSF, IFNγ, IL-1β, IL-2, IL-4, IL-5, IL-6, IL-7, IL-8, IL-10, IL-12 (p70), IL-13, IL-17A, MIP-1β, TNFα. The results obtained during the study showed not only a change in the number of cytokines, but also a change in the balance of pro- and anti-inflammatory cytokines, cytokines that regulate forms of development of acquired immunity, in the group of patients with type 2 diabetes in the post-Covid period. In the post-Covid period, in patients with type 2 diabetes mellitus, the concentrations of cytokines secreted by Th1, Th2, Th17 cells, and Tregs sharply decreased. It has been determined that patients with type 2 diabetes mellitus after SARS-CoV-2 infection develop a functionally inferior virus-specific T-cell response, characterized by reduced or suppressed secretion of the cytokines GM-CSF, IFNγ, IL-1β, IL-2, IL -4, IL-5, IL-6, IL-7, IL-8, IL-10, IL-12 (p70), IL-13, IL-17A, MIP-1β, TNFα. A weak T-cell response may increase the likelihood of developing pathological processes associated with an inadequate response to viral antigens (including repeated infections with the SARSCoV-2 virus, exacerbation of chronic infections).

Authors: Upryamova Ekaterina Yu. , Shifman Efim M. , Degtyarev Pavel A. , Snezhko Vera D. , Maksimkina Tatyana A.
Published: January 2024

BACKGROUND: The objective assessment of pain levels during labor, postpartum period, and effectiveness of analgesic response remains difficult. We suppose that the dynamics of the activity of the sympathetic nervous system by measuring the galvanic skin response may become a promising method for solving this problem.
OBJECTIVE: To evaluate the effectiveness of various multimodal analgesia regimens after cesarean section using the NeonFSC stress monitoring system.
MATERIALS AND METHODS: A prospective single-center clinical comparative study was conducted to evaluate the effectiveness of various postoperative multimodal analgesia regimens in 48 postpartum women who underwent elective cesarean section under spinal anesthesia. For postoperative analgesia, group 1 (n=24) underwent a TAP block, and ketorolac and tramadol were prescribed, and group 2 (n=24) received only ketorolac and tramadol. Randomization was made using the envelope method. The visual analog scale (VAS) and NeonFSC system were used to assess the effectiveness of postoperative pain relief. The observation time was 19–22 h.
RESULTS: The patients were comparable in age, gestational age, physical status, method of pain management and delivery. At baseline and during the 2-h postoperative period, the median and distribution of visual analogue scale pain scores did not show a statistically significant difference between groups. During the study period, the highest level of spectral power of skin conductance (SC) was recorded in group 2. Baseline skin conductance variability (SCV) values were comparable between groups (p 0.001). Lower SCV values were noted in patients of group 1, compared to group 2, at night (p=0.003 vs p 0.001). The median values of the level of total spectral power of skin conductivity (DASS) in patients of group 1 were 1.5–2 times lower, starting from the second hour until the end of observation.
CONCLUSION: The NeonFSC system can be a component of an objective assessment of the effectiveness of analgesia after cesarean section.

Published: January 2024

BACKGROUND: The possibility of reducing doses of narcotic analgesics during the perioperative period is widely discussed in modern scientific literature. This direction is called opioid-free anesthesia and is used in abdominal surgery, oncology, gynecology, and other areas. Publications on the use of opioid-free anesthesia in thoracic surgery are scarce.
OBJECTIVE: To evaluate the analgesic effectiveness of intravenous lidocaine infusion as a component of anesthesia in thoracic surgery.
MATERIALS AND METHODS: Ninety patients who underwent open lobectomy or pneumonectomy were examined. Depending on the analgesic component, patients were divided into three groups: group 1 (n=30) received intravenous infusion of lidocaine, group 2 (n=30) received epidural block, and group 3 (n=30) had fentanyl infusion. Blood pressure, heart rate, cortisol, and blood serum glycemia levels were measured. The intensity of postoperative pain syndrome and the need for promedol, tramadol, and sanitation fibrobronchoscopy were assessed. Arterial hypotension and frequency of postoperative nausea and vomiting were recorded. The length of stay of the patients in the intensive care unit and hospital was recorded.
RESULTS: Cortisol levels did not differ between groups (p=0.26). The glucose level in the epidural block group was significantly lower than that in other groups (p=0.011). A significant increase in mean blood pressure and heart rate was observed in the opioid analgesia group (p 0.001). The lowest severity of pain 6 h after surgery was observed in the epidural blockade and lidocaine groups (p 0.001). Perioperative hypotension was more common in the epidural analgesia group (p=0.045). The incidence of postoperative nausea and vomiting was higher in the opioid anesthesia group (p=0.004). In the fentanyl infusion group, sanitary fibrobronchoscopy was more often required to eliminate atelectasis (p=0.039). The number of bed days spent in the ICU was significantly higher in the opioid analgesic group (p=0.002); however, no significant differences were noted between the groups regarding the number of days spent in the hospital (p=0.228).
CONCLUSION: Opioid-free anesthesia based on intravenous lidocaine infusion, as a component of anesthetic management in thoracic surgery, provides sufficient perioperative stability of hemodynamic and neuroendocrine status, has a pronounced analgesic effect, with less opioid consumption on the first day after surgery, and helps reduce the length of stay in the intensive care unit and hospital.

Published: January 2024

At present, an increasing number of specialists prefer the fast-track surgery concept. One of the significant perioperative complications that can affect the rate and quality of postoperative rehabilitation is the development of neuropathy, which can be the result of improper patient positioning on the operating table, and direct intraoperative damage to the nerve / trunk / plexus. Physical (mechanical compression, stretching, and partial / complete intersection of the nerve with a needle, scalpel, or electrode) and chemical (toxicity of local anesthetics and chemically active liquid effects) mechanisms for neuropathy formation can be described. To prevent the development of a neurological deficit, both the anesthesiologist and surgeon must take all the necessary measures to prevent neuropathies and begin appropriate treatment as soon as possible in the case of its occurrence. This article discusses the anatomy, physiology, and pathophysiology of the peripheral nerve, mechanisms of compression-ischemic neuropathy formation, and perioperative positional problems. Existing recommendations for the treatment of peripheral neuropathic were assessed and proposed for use not only with conservative therapy methods but also with interventional methods for the treatment of established perioperative neurological complications. A summary table of the possible clinical manifestations of postoperative neuropathic is presented.
Exergy Analysis of Supercritical CO2 System for Marine Diesel Engine Waste Heat Recovery Application

Published: January 2024

In this research is performed an exergy analysis of supercritical CO2 system which uses various
waste heat flows from marine diesel engine to produce additional mechanical power. The performed
exergy analysis contains whole system as well as each system component individually. The observed
system produces useful mechanical power equal to 2299.47 kW which is transferred to the main
propulsion propeller shaft. Additionally produced mechanical power by using waste heat only will
reduce marine diesel engine fuel consumption and exhaust gas emissions. Main cooler has the highest
exergy destruction of all system components and simultaneously the lowest exergy efficiency in the
observed system, equal to 32.10% only. One of the possibilities how main cooler exergy efficiency
can be increased is by decreasing water mass flow rate through the main cooler and simultaneously by
increasing water temperature at the main cooler outlet. Observed system has five heat exchangers which
are involved in the CO2 heating process, and it is interesting that the last CO2 heater (exhaust gas waste
heat exchanger) increases the CO2 temperature more than all previous four heat exchangers. Whole
analyzed waste heat recovery supercritical CO2 system has exergy destruction equal to 2161.68 kW
and exergy efficiency of 51.54%. In comparison to a similar CO2 system which uses waste heat from
marine gas turbine, system analyzed in this paper has approximately 12% lower exergy efficiency due
to much lower waste heat temperature levels (from marine diesel engine) in comparison to temperature
levels which occur at the marine gas turbine exhaust.

¿Cómo definimos la unidad territorial metropolitana? ¿Cómo establecemos límites territoriales que garantizan la integración de sus sistemas ecológicos y sociales? ¿Cómo gestionamos los flujos migratorios y los condicionantes del cambio climático que ejercen presión sobre las infraestructuras metropolitanas? En los últimos años, la literatura de desarrollo ha revelado conflictos emergentes de las metrópolis de América Latina y el Caribe. Las preguntas parecen ser simples y de naturaleza apremiante, pero las respuestas implican desafíos críticos de conocimiento y coordinación institucional. Por ejemplo, reconocemos que las personas se mueven, interactúan y satisfacen sus necesidades más allá de los límites político-administrativos, pero no existen suficientes arreglos institucionales que consideren conjuntamente los sistemas de movilidad y la distribución de servicios y bienes territoriales. Esta publicación nos invita a revisar nuevamente la forma en que hemos delimitado la Unidad Territorial Metropolitana. Los contenidos se organizan en tres capítulos que avanzan hacia la construcción de una gobernanza sensible a su escala y complejidad dentro de la región. El primero reflexiona sobre la escala, incluyendo perspectivas históricas y técnicas, como la incorporación de tecnologías que actualizan datos geoespaciales de ocupación y cambio de uso de suelo. El segundo profundiza en las dimensiones de complejidad e intersectorialidad, como la economía, la movilidad, la equidad, el cambio climático, la salud, la calidad de vida y los desafíos de la migración. El tercero se nutre del conocimiento acumulado para recorrer aspectos claves de la gobernanza metropolitana y su sostenibilidad fiscal. Por último, la revisión de experiencias internacionales entrega lecciones sobre las distintas formas en que se ha asumido la unidad metropolitana dentro de las infraestructuras institucionales. Es necesario anticipar aspectos claves de la escala y las dimensiones necesarias para construir acuerdos institucionales efectivos. La invitación es a definir antes de formular una gobernanza metropolitana.

O desenvolvimento do sector imobiliário do agroturismo tem trazido muitos benefícios para a economia nacional e também contribui para aumentar o valor do património imobiliário e melhorar a vida das populações locais. O imobiliário de agroturismo é um modelo que muitos países estão a apontar para o futuro na direção do desenvolvimento sustentável do agroturismo. O desenvolvimento deste modelo ajuda a aumentar o valor dos produtos agrícolas regionais, criando fontes de rendimento adicionais para a população local, contribuindo para fazer do Vietname um dos novos e mais atraentes destinos turísticos do Sudeste Asiático e do mundo. No entanto, no processo de implementação de actividades relacionadas com o sector imobiliário do agroturismo, existem ainda algumas desvantagens e limitações. Em particular, o sistema jurídico vietnamita que rege o planeamento e a gestão do imobiliário turístico não está completo, e muitas “lacunas” jurídicas não foram ultrapassadas, o que dificulta o desenvolvimento do imobiliário de agroturismo. Por conseguinte, o presente artigo analisa a regulamentação jurídica relativa aos bens imobiliários do agroturismo no Vietname a partir da prática na província de Thanh Hoa, a fim de identificar as limitações, as lacunas e as causas destes problemas e propor algumas soluções para aperfeiçoar a lei.

El clavel tiene gran importancia para la floricultura colombiana, siendo Dianthus barbatus, en sus variedades Kiwi Mellow y Green Ball, una alternativa de crecimiento del sector, debido a la belleza que aporta a los arreglos florales. No obstante, las empresas colombianas necesitan innovar y optimizar recursos para llevar un manejo adecuado del espacio de siembra y así mejorar su productividad. Por lo anterior, se evaluaron diferentes densidades de siembra y contenedores en las variedades mencionadas, para lo que se empleó un diseño completamente aleatorizado con cuatro tratamientos por variedad (23 plantas/m2, dos contenedores por cama; 46 plantas/m2, dos contenedores por cama; 27 plantas/m2, un contenedor por cama; 54 plantas/m2, un contenedor por cama), con cuatro repeticiones por tratamiento. La densidad de siembra de 54 plantas/m2 en un contenedor por cama, para las variedades Kiwi Mellow y Green Ball, tuvo un efecto significativo sobre la productividad, incrementando los rendimientos en 30 % y 20%,respectivamente, en comparación al tratamiento común de la zona (densidad de siembra de 23 plantas/m2). El aumento de las densidades de siembra no afectó los parámetros de calidad de la flor, ni aumentó las pérdidas por calidad nacional. La variedad Kiwi Mellow tiene un 3,16 % más de unidades Soil Plant Analysis Development (SPAD) en promedio que Green Ball. La mejor rentabilidad en el cultivo de D. barbatus para las dos variedades evaluadas fue obtenida con la densidad de siembra de 54 plantas/m2, superando respectivamente en un 34 % y 15 % al tratamiento de la zona.

Predecir el comportamiento de los contaminantes atmosféricos se ha convertido en un importante insumo para el diseño de estrategias gubernamentales de contingencia que buscan mitigar los niveles de contaminación, por tal motivo esta investigación presenta una metodología para predecir el incumplimiento de los índices máximos permitidos para el material particulado contaminante PM 2.5, a partir de modelos estadísticos multivariados que pueden ser utilizados para entender cómo diversas variables meteorológicas influyen en el comportamiento del contaminante, al igual que como forma de seleccionar las variables que serán usadas durante el entrenamiento de un clasificador bayesiano de redes neuronales. Además del modelo multivariado, se aplicó un análisis de varianza multifactorial para evaluar el efecto del día, hora y mes en la media del PM 2.5. Como resultados principales, se encontró que las variables: dirección del viento, temperatura, humedad, presión atmosférica, precipitación, radiación solar, hora deldía, día de la semana y mes, fueron estadísticamente significativas y permitieron entrenar una red neuronal con una capacidad de pronóstico del 78,2 % de manera global y del 81 % en los casos de incumplimiento, demostrando así que con variables factibles de manejar (variables meteorológicas, hora, día y mes) se puede diseñar una herramienta de pronóstico muy útil como insumo para la gestión sobre la calidad del aire.

Una cantidad importante de estudios ha evidenciado que la personalidad influye de manera positiva en el ámbito de la ingeniería de software. Sin embargo, solo unos pocos estudios empíricos han analizado la influencia de la personalidad en los atributos de calidad del software. El objetivo de este trabajo es evaluar los efectos que tiene la formación de grupos homogéneos bajo la dimensión de la meticulosidad, con respecto a la mantenibilidad en sistemas orientados a objetos y la adecuación funcional del producto software. Se contó con un total de 76 participantes, y se empleó una herramienta computacional basada en un mecanismo de algoritmo genético, considerando la personalidad de los estudiantes como criterio de agrupación. Como resultado, se evidenció que no existe una diferencia significativa que permita afirmar que la formación de grupos homogéneos haya obtenido mejores resultados con respecto a las métricas Chidamber & Kemerer (CK) y a la adecuación funcional. A pesar de estos resultados, las puntuaciones promedio de las métricas Coupling Between Objects (CBO) y Response for a Class (RFC) en el grupo experimental estuvieron ligeramente por encima del umbral deseado y ligeramente por debajo del promedio del grupo de control. Esto indica que la meticulosidad en la formación de grupos podría afectar la complejidad del diseño, la modularidad, la propensión a fallas y la facilidad de realizar pruebas en las clases. Se sugiere seguir explorando qué dimensiones específicas de la personalidad pueden influir en los diferentes atributos de calidad del software y en general de la ciencia de la computación.

Published: January 2024

The firm’s decision to become a public firm is very interesting to analyze and reveal its performance. This study aims to reveal the firm’s performance in the short and medium term after conducting an initial public offering (IPO). In addition, the choice of the IPO strategy, that are share-only IPO (SIPO) or package IPO (PIPO) also affects the firm’s performance. Annual reports of up to 3 years of 155 companies conducting IPOs from 2010 to 2016 are used to examine the short-term and medium-term impacts of the IPO process. A very surprising result of this study is that IPO companies cannot show better performance in the short and medium term after the IPO, including State-Owned Enterprises (SOE), it gets worse if the company decides to use PIPO as a strategy during the IPO.

This study will discuss about all SKPD that work in the Indonesian provincial government. Multiple-linear regression was the method used for data analysis. The hypothesis testing table demonstrates that the budget planning variable has little bearing on how much money is spent. Budget absorption is significantly impacted by the budget implementation variable.
