Interacción y convergencia de saberes en la tradición “clásica” sobre interdisciplinariedad: Un esquema de sistematización conceptual
Authors: Berridy Damián , Fernández Guillermet Armando
Published: March 2022

El trabajo se propone analizar la multiplicidad de formas de convergencia, combinación o hibridación disciplinar propuestas en la literatura. La investigación tiene por base un esquema gradualista de interacción entre disciplinas, con raíces en la denominada tradición “clásica” de teorización surgida en Europa hacia 1970. El resultado clave del trabajo es un esquema terminológico-conceptual fundado en la diferencia entre acepciones “en sentido amplio” y “en sentido estricto” de la interdisciplinariedad. El esquema permite sistematizar la diversidad de propuestas analizadas, incluyendo una forma clave de la transdisciplinariedad.

Mujeres y poder. Una mirada poliédrica a la sociedad actual
Authors: García de León María Antonia
Published: March 2022

El poder es el gran estructurador de género en nuestras sociedades. Es el gran vertebrador de la vida social. Y es el gran tema de las ciencias sociales, el tema por antonomasia. Orientar el conocimiento y el cambio social hacia las verdaderas necesidades emocionales de los ciudadanos, la capacidad de sustentación del planeta y la paz social es una tarea fundamental y urgente que rompe la disociación entre razón y emoción, esencia del orden patriarcal. Orden que ha diseñado políticas cada vez más alejadas de la realidad humana, que ha arrojado sobre el mundo la pandemia más letal de nuestra contemporaneidad. Estamos ante un dosier de gran calado académico y de gran practicidad. Este carácter bifronte del trabajo reunido lo llena de valor. Por un lado, su lectura conduce a un arsenal de conocimientos con los que se puede dialogar y argumentar inteligentemente, lo que nos facilita una mirada poliédrica sobre nuestra sociedad, además de enriquecernos con un cúmulo de observaciones. Por otro lado, este dosier está volcado a la crítica social, a inspirar a quienes se dedican a la acciónsocial. Ambos aspectos dotan a la obra de peso y de pasión.
Conversaciones significativas sobre cambio climático: reflexiones sobre género y poder
Authors: Piñeiro Concepción , Iniesta-Arandia Irene , González Hidalgo Marien
Published: March 2022

Este artículo explora cómo las perspectivas feministas, en relación a las dinámicas de género y poder, aportan a las formas transformadoras de abordar la actual crisis climática. En la primera parte del artículo introducimos la necesidad de una mirada feminista a la hora de analizar los impactos diferenciales del cambio climático en relación al género, la clase, la et-nia, etcétera, así como el papel de los liderazgos de las mujeres en el activismo, las negociaciones y toma de decisiones políticas, y en la ciencia. En la segunda parte, presentamos cómo la facilitación de conversaciones públicas y colectivas que incorporan estas cuestiones, a partir de la experiencia de foros abiertos en Madrid, permite reflexiones en torno al cambio climático como una experiencia cotidiana, la atención a las emociones y las experiencias vividas, la interseccionalidad y la ecodependencia e interdependencia, así como respecto a diferentes formas de liderazgo. Este tipo de conversaciones y encuentros pretenden aportar al trabajo necesario de seguir ampliando las aproximaciones feministas al cambio climático.
Empoderamiento de profesoras y uso de las tecnologías digitales para la enseñanza de las matemáticas durante el confinamiento por COVID-19
Authors: Simón Ramos María Guadalupe
Published: March 2022

La situación de las mujeres profesoras de matemáticas en México tiene características que están fuertemente asociadas a cómo se han constituido la matemática escolar y su enseñanza dentro de una cultura patriarcal. Analizamos la presencia de las profesoras en México y el proceso de empoderamiento de un grupo de ellas en un nivel educativo y área de conocimiento en el que representan una minoría (preuniversitario). Aprovechamos la oportunidad que representa la necesaria incorporación de los entornos virtuales a la educación durante el 2020. Integramos la epistemología feminista y la teoría socioepistemológica de la matemática educativa como las perspectivas que nos permiten analizar cómo su condición de género marca su relación con la matemática escolar y con las tecnologías digitales. Identificamos una baja autovaloración de sus capacidades, pero también que la mayoría de las profesoras fueron capaces de transformar su práctica e integrar nuevas tecnologías digitales.
Canción popular e imagen de la mujer en la transición española
Authors: Aguilar Antonio
Published: March 2022

La transformación de la imagen de la mujer a lo largo del último medio siglo ha sido mayoritariamente abordada por la crítica literaria desde una perspectiva académica y «elitista» y con ello se ha obviado el significativo papel que la cultura popular ha jugado históricamente en el cambio de paradigmas culturales (desde el romancero tradicional al pop-art). Con este acercamiento se pretende poner el foco sobre la importancia que han tenido en la sociedad española de los setenta y primeros ochenta las distintas (y heterodoxas) imágenes de la mujer construidas por las canciones populares, que supusieron un cambio sustancial de los estereotipos femeninos en el imaginario sociocultural del momento.
Miguel Prados Such: un psiquiatra reformista en el exilio (Málaga, 1894-Montreal, 1969)
Authors: García Díaz Celia
Published: March 2022

El proceso de legitimación de la psiquiatría como especialidad médica en España comenzó a desarrollarse en la década de los años veinte gracias al interés de una generación de jóvenes médicos que se habían formado en la tradición de la medicina de laboratorio con Ramón y Cajal. Miguel Prados Such, malagueño de nacimiento pero formado como médico en la Universidad Central de Madrid, ha sido más conocido por ser hermano del poeta Emilio Prados que por sus propios logros en el ámbito científico, a pesar de sus numerosas publicaciones y su intensa actividad asociativa. Tras su exilio a Canadá al terminar la Guerra Civil española, el rastro de este investigador se diluye en nuestro país. El objetivo de este trabajo es poner en valor la figura de este médico, mostrar sus aportaciones al mundo de la medicina mental, resaltar su interés por reformar la institución psiquiátrica de la Beneficencia en Málaga, además de haber sido reconocido en Canadá como uno de los psiquiatras más directamente implicados en la difusión y organización de las sociedades psicoanalíticas desde los años cuarenta.
Az emberi szervezetben élő baktériumok klinikai jelentősége a gyakorlatban
Authors: Fekete Mónika , Szarvas Zsófia , Fazekas-Pongor Vince , Fehér Ágnes , Varga János Tamás
Published: March 2022

Bevezetés: A mikrobiom (az emberi szervezetben élő mikrobák összessége) több milliárd mikroorganizmusból áll, a benne élő fajok diverzitása és épsége döntő szerepet játszik a gazdaszervezet egészségének fenntartásában. A bél mikrobiom össztömege akár a két kilogrammot is elérheti, kb. egyharmada (30%-a) nagy hasonlóságot mutat a fajok között, azonban 70%-a abszolút egyedi azonosító csakis ránk jellemző, mint az ujjlenyomat. Kutatások leírják, hogy a bélflóra összetétele közvetlen kapcsolatban áll számos betegséggel pl. anyagcserezavarokkal, elhízással,  szív- és érrendszeri betegségekkel, depresszióval, asztmával stb. Összefoglaló tanulmányunk célja a mikrobiom és módosulásának bemutatása, valamint a bél mikrobiom megváltozásával összefüggő betegségek áttekintése, továbbá a táplálkozáson, testmozgáson keresztüli pozitív irányú befolyásolása az egészségfejlesztés tekintetében. Módszertan: Hazai és nemzetközi orvostudományi adatbázisok áttekintése mikrobiom, betegségkockázat, diszbiózis és probiotikum keresőszavakkal. Eredmények: A mikrobiomnak fontos szerepe van az immunrendszer szabályozásában és számtalan betegség kialakulásában azonosították additív tényezőként pl. gyulladásos bélbetegségek, metabolikus eltérések (pl. elhízás, inzulinrezisztencia, cukorbetegség), autoimmun betegségek, neurológiai kórállapotok (pl. autizmus, Parkinson-kór, Alzheimer-kór), daganatos betegségek (pl. mellrák, vastagbélrák, májrák) esetében. A környezeti tényezők, a szisztémás gyulladás, a betegségek előfordulásának növekedése, és az ezzel együtt járó gyógyszerszedés megváltoztatja a mikrobiális közösség összetételét, melyet a fizikai inaktivitás és a bélrendszeren történő áthaladási idő megnövekedése még tovább fokoz. Az idősödéssel és a társuló betegségekkel az olyan kedvező baktériumok, mint a Laktobacillusok és Bifidobaktériumok száma csökken, míg a fakultatív anaerobok (Enterobacteriaceae, Streptococcusok,Staphylococcusok) száma nő, mely pozitív irányba befolyásolható egészséges életmóddal, táplálkozással és fizikai aktivitással. Következtetések: Feltételezhető, hogy a bél mikrobiom számos bélrendszeri és bélrendszeren kívüli kórkép patofiziológiájában központi szerepet tölt be. A mikrobiom-kutatás eddigi eredményei alapján elmondható, hogy a testben élő ökoszisztéma egészségünk alapja és mindent meg kell tennünk épségének megőrzése érdekében, mert egészséges életmóddal, megfelelő táplálkozással és mozgással összetétele pozitív irányba befolyásolható és kulcsszerepet tölt be az egészségfejlesztésben.
Giuliana Sorce (Ed.). Global perspectives on NGO communication for social change
Authors: Moist Richard
Published: March 2022

Nongovernmental organizations (NGOs) face an increasingly challenging and complicated context in which to achieve social change. Current trends toward illiberal populism and rising authoritarianism combine with the challenges of fake news and the protracted difficulties caused by the Covid-19 pandemic. In these circumstances, the critical role played by NGOs in civil society has only been heightened. Global Perspectives on NGO Communication for Social Change provides us with a timely and comprehensive examination of the key role that communication plays in enabling NGOs for social change to engage with their stakeholders and to impact society. This edited volume examines how NGOs strive to achieve this. Structured in two parts, the book first focuses on thematic perspectives before then devoting the second half to case studies, which provide the reader with a rich array of initiatives used to communicate and engage audiences. It presents clear global perspectives, as well as giving us nuanced national and local viewpoints from a broad range of countries, including cases from Brazil, Bangladesh, Nigeria, South Africa and China.
Autonomous re-naturalization of cities in a context of degrowth
Authors: Espín Maria
Published: March 2022

Planetary urbanization is considered to be one of the leading causes of the current global process of the degradation of nature, and a reduction in urban consumption becomes, therefore, a crucial goal for degrowth. Three fundamental premises underly an investigation of these issues. Firstly, territorial management underpins global environmental justice through the implementation of conservation policies; Secondly, degrowth narratives must operate in the urban context; and thirdly, there is a need for a paradigm shift at an economic, social and nature-relational level. This article presents two research approaches. Firstly, it sets out a theoretical framework in the field of 'urban degrowth', collecting arguments from political ecology, urban planning, deep ecology and degrowth thinking; and secondly, it proposes a preliminary line of investigation towards the process of urban de-occupation and re-naturalization through a bibliographic analysis of urban-ecological variables fostering natural recovery. The aim of the study is to stir up discussion about urban degrowth, as an essential mechanism to counter increasing land consumption, and global habitat and biodiversity loss. Anthropized landscapes require care for nature, conservation, collective action and initiatives at the practical and experimental level, and further research.

Authors: Tomasi Suzanne E. , Fechter-Leggett Ethan D. , Edwards Nicole T. , Reddish Anna D. , Nett Randall J.
Published: March 2022

OBJECTIVE

To assess proportionate mortality from all causes for male and female US veterinarians during 1979 through 2015.

SAMPLE

Death records for 11,620 veterinarians.

PROCEDURES

For this proportionate mortality ratio (PMR) study, information for veterinarians who died during 1979 through 2015 was obtained from AVMA obituary and life insurance databases and submitted to a centralized database of US death records to obtain underlying causes of death. Decedent data that met records-matching criteria were imported into a software program for calculation of PMRs for all causes stratified by sex and indirectly standardized for age, race, and 5-year calendar period with 95% CIs.

RESULTS

11,620 decedents consisted of 11,049 (95%) males and 571 (5%) females with a median age at death of 77 years. Proportionate mortality for all veterinarian decedents was higher than expected for melanoma (PMRs, 2.1 and 2.2 for males and females, respectively), suicide (PMRs, 2.1 and 3.5 for males and females, respectively), and transportation injuries (PMRs, 1.7 and 1.6 for males and females, respectively). Proportionate mortality for all decedents was lower than expected for respiratory cancers (PMRs, 0.6 and 0.5 for males and females, respectively), diabetes mellitus (PMRs, 0.7 and 0.4 for males and females, respectively), heart disease (PMRs, 0.9 and 0.6 for males and females, respectively), and respiratory disorders (PMRs, 0.7 and 0.6 for males and females, respectively).

CLINICAL RELEVANCE

Results indicated proportionate mortality from malignant melanoma, transportation injuries, and suicide for male and female veterinarians was higher than the general population. These data may help stakeholders improve veterinarian workplace safety and health guidelines.
Large animal veterinarians’ knowledge, attitudes, and practices regarding livestock abortion-associated zoonoses in the United States indicate potential occupational health risk
Authors: Cherry Cara C. , Sureda María E. Negrón , Gibbins John D. , Hale Christa R. , Stapleton G. Sean , Jones Emma S. , Nichols Megin C.
Published: March 2022

OBJECTIVE

To understand large animal veterinarians’ knowledge of select zoonotic diseases that cause livestock abortions and identify barriers to using personal protective equipment (PPE).

SAMPLE

A convenience sample of 469 veterinarians currently working with livestock.

PROCEDURES

We sent an electronic survey invitation to large animal veterinarians through various veterinary organizations. Respondents answered questions addressing knowledge and prior experience with select abortion-associated zoonotic diseases, resources available for infection control, attitudes and barriers to PPE use, and demographics.

RESULTS

Median participant age was 49 years (range, 22 to 82 years), and 54% (235/438) were male. Half of veterinarians (185/348) were contacted 5 or fewer times per year to consult on livestock abortions. No veterinarians surveyed answered all questions on zoonotic disease transmission correctly. Personal protective equipment access varied, from 99% (289/290) having access to gloves to 20% (59/290) having access to respirators. Concerns for spreading disease to other animals (136/289 [47%]) and to other humans (108/287 [38%]) ranked as the most common reported motivators for PPE use. Reported barriers to PPE use among survey participants were the inconvenience of taking PPE into the field (101/286 [35%]) and the inconvenience of wearing PPE (97/286 [34%]). Access to PPE was not correlated with PPE use.

CLINICAL RELEVANCE

Surveyed veterinarians had limited knowledge of transmission of select abortion-associated zoonotic diseases. Incomplete understanding might lead to inappropriate PPE selection, preventable disease exposure, or missed opportunities for client education. Inconvenience was a primary reason PPE was not used.

Published: March 2022

Value added tax (VAT) is an important source of income for European Union countries. The developing countries of the European Union are encouraged to step up their efforts to comply with European legislation for the purpose of sustainable economic development. Knowing that these states are susceptible to corruption, this paper investigates the relationship between the efficiency of VAT collection, the VAT gap and the level of the corruption index in the developing countries of the European Union.
Effect of the polymorphism of genes related to lactogenesis in pigs on colostrum and milk composition and on rearing performance of piglets
Authors: Szyndler-Nędza Magdalena , Mucha Aurelia , Ropka-Molik Katarzyna , Piórkowska Katarzyna
Published: March 2022

The aim of the study was a search for new polymorphisms in the genes related to lactogenesis, including lactose synthesis in colostrum and milk, and determine their relationship with the content of colostrum and milk components and body weight of the piglets. Colostrum and milk were sampled during the second lactation on d 1, 7, 14 and 21 from 112 sows of Polish Large White (PLW) and Polish Landrace (PL). The piglets’ rearing performance was determined based on the number and body weight at 1, 7, 14 and 21 d of age. In the study six polymorphisms located in different genes were analysed. Among the six polymorphisms under analysis, those identified in the B4GALT1 genes had the most significant effect on colostrum and milk composition and the piglets’ body weight changes. Sows of the B4GALT1GG
genotype, when compared to those of B4GALT1AA
, produced colostrum and milk with a significantly lower lactose content and reared piglets with a substantially higher body weight (by 0.30 kg) at 21 d of age.
Comparison of raw cow milk microbiota in two milking systems: A field study
Authors: Tu Po-An , Yang Ming-Kuei , Yu Yu-Hsiang
Published: March 2022

This study investigated the effect of different milking systems on the milk composition and microbial community of raw milk in a commercial dairy farm. Raw milk samples from conventional milking system (CMS) and automatic milking system (AMS) were collected and the microbiota on each was assessed by 16S rRNA gene sequencing. Results showed that the acetone (P = 0.031) and β-hydroxybutyrate (P≤0.001) levels in the raw milk of the AMS group were increased compared with the CMS group. Principal component analysis, unweighted and weighted principal coordinates analysis, and heat map of microbial community composition in the raw milk showed a clear separation between two groups. AMS increased the abundance of the genera Acinetobacter (FDR = 0.004) and Staphylococcus (FDR = 0.004) in the raw milk compared with the CMS group. In contrast, the abundance of the genera Pseudomonas (FDR = 0.028), Lactococcus (FDR = 0.015), Sphingobacterium (FDR = 0.004), Brevundimonas (FDR = 0.005), and Chryseobacterium (FDR = 0.042) in the raw milk was reduced in the AMS group compared with the CMS group. The abundance of the genera Acinetobacter and Staphylococcus in the raw milk was positively correlated with the β-hydroxybutyrate, acetone, free fatty acid, citric acid, and urea nitrogen levels. Furthermore, the abundance of the genus Acinetobacter in the raw milk was negatively correlated with the somatic cell counts. The study demonstrates that the introduction of AMS in the dairy farm can regulate microbiota composition in the raw milk and this modification may exert an effect on reducing the somatic cell counts in the raw milk.
Sudden death syndrome in broiler chickens: a review on the etiology and prevention of the syndrome
Authors: Sosnówka-Czajka Ewa , Skomorucha Iwona
Published: March 2022

Sudden death syndrome (SDS) is a condition in which apparently healthy broiler chickens die suddenly. There are short convulsions and frantic wing-beating prior to death, and the weight of internal organs is the same as in healthy chickens. The exact etiology of SDS is unknown. Heart problems have been implicated as a potential cause of the disease in broiler chickens. Despite considerable research, effective methods of prevention are still being sought. Furthermore, the prophylactic measures often make production less profitable (reduced body weight gain resulting from restricted feeding) and prolong the growth period. It is necessary to continue research on SDS, in particular on stimulation of the cardiovascular system to reduce the susceptibility of broilers to sudden death syndrome under intensive production systems.
Nanowater enhances cryoprotective properties of glycerol-containing extenders used for ram semen freezing: A preliminary study spanning laboratory testing
Authors: Szymanowicz Joanna , Murawski Maciej , Schwarz Tomasz , Bartlewski Pawel M.
Published: March 2022

It has been suggested that nanowater (NW-water declustered in the cold plasma generator and characterized by a low freezing point and high diffusivity) could improve ram semen quality after freezing in glycerol-containing extenders. Eighteen ejaculates from six Olkuska rams were divided into six equal portions each, and then diluted (800×106 spermatozoa/ml) and frozen in the fructose-skimmed milk-egg yolk Kareta extenders containing 3% or 7% of glycerol. The extenders were prepared with deionized water (DW-3% and DW-7%) or NW declustered for 15 min (NW15’) or 30 min (NW30’). Post-thaw sperm motility, proportions of sperm defects and percentages of apoptotic, necrotic, and live spermatozoa were determined. The proportion of spermatozoa with midpiece defects was lower (P<0.05) in NW15’-3% compared with DW-3%. Sperm progressive motility was greater (P<0.05) for spermatozoa cryopreserved in both NW30’ (NW30’-3%/7%) extenders compared with their respective controls (DW30’-3%/7%). The proportion of necrotic spermatozoa 1 h after thawing was lower (P<0.05) in NW30’-7% compared with DW-7%, whereas the proportion of live cells detected immediately and 1 h after thawing was greater (P<0.05) in NW30’-7% than in DW-7%. In summary, NW enhanced cryoprotective effects of glycerol-containing extenders with an increase in sperm viability being greater with 7% than 3% of glycerol. Different declustering times appear to alter NW properties. These observations merit future studies of the utility of NW for semen cryopreservation in rams and other mammalian species. The specific mechanisms whereby NW ameliorates the quality of frozen-thawed ram spermatozoa remain to be elucidated.
Effect of supplementation of freezing media with isoespintanol on functional integrity of equine semen
Authors: Restrepo Giovanni , Usuga Alexandra , Montoya Juan David , Rojas Mauricio , Rojano Benjamín
Published: March 2022

Adding antioxidants to semen extender has become one of the major strategies to reduce the damage caused by freezing to stallion sperm. Isoespintanol (Iso) is a natural antioxidant that is known as a good free radical scavenger. The aim of this research was to evaluate the effect of supplementation of freezing media with Iso on functional integrity of equine semen. Semen from five Colombian Creole horses was frozen with 0, 10, 20, 30, 40 and 50 µM Iso. Post-thawing motility and kinetics, structural membrane integrity (SMI), normal morphology (NM) and functional membrane integrity (FMI) of sperm were evaluated. Seminal quality (SQi) and seminal velocity (SVi) indexes were calculated. Through a flow cytometric analysis, mitochondrial membrane potential (ΔΨM), viability and DNA integrity of frozen-thawed semen were assessed. General linear models were adjusted, and means comparisons were performed using Tukey’s test. The significance level was P<0.05. No differences for post-thaw sperm quality parameters were found, except for total motility, which showed a reduction by adding 40 µM Iso (P<0.05). However, the estimation of indexes, showed that supplementation with 20 or 30 µM Iso before semen freezing, can increase post-thaw SQi and SVi values of some horses. A higher proportion of high-∆ΨM sperm for 20 µM Iso was found. It is concluded that Iso can improve the quality and mitochondrial activity of frozen-thawed equine semen, however its effect can vary according to the horse and in high concentrations it could have detrimental effects.

Published: March 2022

The present study was aimed to evaluate the moderating properties of lavender (Lavandula officinalis) essential oil (LEO) against immunotoxic effects of the organophosphate pesticide, malathion in rainbow trout, Oncorhynchus mykiss. For this purpose, fish were supplemented with LEO at dietary concentrations of 0.5, 1, 2 and 4 ml/kg diet LEO for 56 days. A non-LEO supplemented group was also considered as control. After 57 days feeding trial, biochemicals were assayed in the blood and kidney tissue and then fish exposed to a sub-lethal concentration of malathion [0.24 mg/l equal to 30% of LC50 (0.8 mg/L)]. After 57 days feeding trial, the serum total immunoglobulin, respiratory burst activity, lysozyme activity and complement activity significantly elevated in fish treated with 1 and 2 ml LEO/kg diet compared to non-LEO supplemented individuals (P<0.01). Such changes were not observed in non-LEO supplemented fish (P>0.01). Significant elevations were observed in the expression of the immune genes (iNOS and C3 genes) in fish treated with 0.2–2 mg LEO/kg diet compared to non-supplemented ones (P<0.01). The lysozyme and complement activity significantly decreased in fish fed 4 ml/kg diet (P<0.01). After exposure to malathion, all immune components significantly declined in control and those treated with 0.5, 1 and 4 ml LEO/kg diet (P<0.01). In contrast, the immunity components exhibited no significant changes in fish treated with 2 ml LEO/kg diet after exposure (P>0.01). The expression of iNOS and C3 genes significantly reduced in control and fish fed 0.5, 1 and 4 ml LEO/kg diet in response to malathion (P<0.05). Furthermore, the expression of these genes showed no significant changes in fish fed with 2 ml LEO/kg diet after exposure (P>0.01). The findings of the present study suggested an immunoprotective role for dietary LEO at optimized dietary concentrations of 1 and 2 ml LEO/kg diet against oxidative stress and toxicity induced by malathion. Nevertheless, LEO at high dietary concentration (4 ml/kg diet) had reducing effects on the fish immunity.
Potential for carbon sequestration and the actual forest structure: the case of Krasnodar Krai in Russia
Authors: Efimov Oleg , Gura Dmitry , Makar Svetlana , Mustafin Radik
Published: March 2022

This work aims to analyze the age structure of forests in Krasnodar Krai in order to estimate their carbon sequestration potential. The research was conducted during 2015–2020 in 14 forested districts of Krasnodar Krai in the Russian Federation. A database of 96,000 sample plots was used. Aspen occupied the maximum area (20% of trees), while much smaller areas were occupied by linden, birch, pine, and oak (p≥0.05 with aspen). Spruce occupied three times smaller areas compared to aspen (p≤0.05), while maple, elm, ash, and alder had ten times smaller areas (p≤0.01). Among deciduous species by age, mature and overmature stands predominate, while in conifers a young growth prevails (44% – for pines). All pine forests belong to the 1st quality class (91%), for birch and aspen, it is 75–80% of trees (p≤0.05 with the frequency for pine), for spruce – 52% (p≤0.05), and for oak – 10% (p≤0.01). Different tree species make different contributions to carbon sequestration – from 0.3 tons per 1 ha (Alnus glutinosa) to 1.7 tons per ha (Fraxinus excelsior). Taking into account the areas occupied in the forest by different tree species, their contribution will also be different – from 0.5 thousand tons/1 year (F. excelsior) to 290 thousand tons per 1 year (Populus tremula). The total increase in wood stocks and carbon sequestration is mainly due to six forest tree species. The results obtained can be used to assess the potential for carbon sequestration in temperate forests, taking into account their different age structure and tree species composition.
The Adoption and Implementation of High-Performance Work System in Subsidiaries of Japanese Multinational Companies in Vietnam: a Qualitative Study
Authors: Tran Huy Phuong , Dinh Thi Ngoc Quynh , Nguyen The Kien
Published: March 2022

Background and purpose: Managing human resource in foreign subsidiaries of Multinational Companies (MNCs) has been a challenging task due to the cultural diversity. High Performance Work System (HPWS) has been adopted by headquarters of MNCs in their subsidiaries as a form of control. The current research aims to explore the adoption and implementation of HPWS in subsidiaries of Japanese MNCs in Vietnam.

Design/Methodology/Approach: A qualitative research design was conducted with data collected from semi-structured in-depth interviews with 33 managers working in 11 subsidiaries of Japanese MNC in Vietnam. Content analysis was used to analyze the data.

Results: The results suggested that although HPWS was not fully implemented in these establishments, ability enhancing, motivation enhancing and opportunity enhancing bundle of HPWS were adopted to a varying extent. In addition, HPWS was adopted as a reactive response rather than a strategic choice. Finally, cost-benefit consideration may provide explanation for the non-systematic implementation of HPWS in affiliations of Japanese MNCs in Vietnam.

Conclusion: The research provides some evidences to support the best-fit approach to HPWS adoption and implementation. Although HPWS has the potential to improve organizational performance, it must be internally aligned with the context of the organization.

OBJECTIVES. To evaluate measurements of sella turcica on computerized tomography (CT) scans.

MATERIAL AND METHODS. Using CT images of 185 subjects (122 male, 63 female), sella length (SL), posterior clinoid height (PCH), tuberculum sella (TS), sella height anterior (SA), sella middle height (SM), sella height posterior (SP), and sella anterior-posterior dimension (SAP), sella types (oval, circular and flattened) were measured in age groups (< 26, 26–40, 41–60, and > 60 y).

RESULTS. In the 41-60y group, the SL and SAP dimensions of the males (n=39) and SM, TS and PCH of the females (n=17) were longer than in the younger group [for males, 26-40y (n=32) and < 26y (n=38) groups; for females, 26-40y (n=19) and < 26y (n=19) groups]. In both males and females, mainly the circular type sella was observed (64.8% and 74.6%, respectively). The SL and SAP distance of the flat sella (n=46) was significantly longer, and the PCH, TS, SA and SM measurements of the flat sella were significantly shorter than those of the oval (n=13) and circular types (n=126).

CONCLUSION. The development of sella turcica continues through the age of 41 to 60 years. In the male group, growth was detected mainly in the anterior-posterior direction. The reason for this may be related to the decrease in the pars anterior of the pituitary gland and the enlargement of the pars posterior of the pituitary gland. However, in females, growth was detected mainly in the vertical direction. This is thought to be due to pituitary stalk elongation.

The web-based behavior of online learning: An evaluation of different countries during the COVID-19 pandemic
Authors:   Technical College of Engineering, Duhok Polytechnic University, Duhok, 42001, Iraq, Mohammed Dilkhaz Yaseen
Published: March 2022

COVID-19, a pandemic that the world has not seen in decades, has caused several new obstacles for student learning and education throughout the globe. As a consequence of the worldwide surge of COVID-19 instances, several schools and institutions in almost every region of the globe have closed in 2020 or switched to online or remote learning, which will have a variety of repercussions for student learning. This has led to educators and students spending more time online than ever before, with both groups researching, learning, and familiarizing themselves with information, resources, tools, and frameworks to adapt to online or remote learning. Data mining and analysis are being done to analyze such online activity. For the construction of this dataset, the web-based data in the form of search interests connected to online learning, gathered through Google searches, was mined using Google Trends. Currently, the dataset comprises web-based data related to online learning for the 20 nations that COVID-19 negatively touched at the time of its construction. This project aims to create and evaluate time-series forecasting models of a country's end-of-term performance, explore how the pandemic has influenced the migrations of people throughout the globe, and estimate the nations' future online learning needs. Regression techniques such as linear regression, multilayer regression, and SMO regression are utilized. This is done by looking at previous data, identifying the trends, and creating short-term or long-term projections. The data demonstrate that the approach of SMO regression causes fewer errors with improved accuracy compared to others.

Una perspectiva de género a través de una sociedad matriarcal: la zarzuela La isla de San Balandrán
Authors:   Universidad de Sevilla (España), Toledo Escobar María
Published: March 2022

This article analyzes from a gender perspective what the zarzuela chica La isla de San Balandrán meant in the 19th century Spanish society. Taking into account the upside-down-world scenario (in this island women have the power and men don’t have either voice nor vote), it is interesting to initiate an investigation with regard to what this change of perspective meant to the critics and the audience, whether there was a change in society, or a seed was sown so that men could understand the limits to which women of the time were subjected. Through journal and magazine documents as well as the subsequent sequels that the piece left in some literary works, the evolution of collective thought will be traced as well as how little by little feminism was introduced in 19th century Spain.

Поиск оптимального плана при оперативном планировании производства является трудной задачей из-за двух факторов - быстрый рост пространства поиска с увеличением размерности и серьезное ограничение вычислительного ресурса для того, чтобы построенный план оставался актуальным при непрерывно изменяющемся состоянии производства. В данной статье рассматривается подход к решению задачи составления расписания с помощью выбора приоритета операций для каждой из партий. Для решения задачи используются бионические алгоритмы, а именно генетический алгоритм, алгоритм роя частиц и дифференциальная эволюция. Кроме того, рассматриваются саконфигурируемые версии алгоритмов и алгоритм кооперативной коэволюции на их основе.
