Published: February 2025

The subject of this communication is the evaluation of the results of pedagogical research focused on environmental-technical university education within the framework of a four-year PL-CZ project supported by the EU, entitled “Cooperation between the University of Opole and the University of Hradec Kralove increasing the employability of graduates on the cross-border labour market” and its three-year sustainability, which we have already reported on in a previous communication in this Journal. The aim was to increase the mutual cross-border substitutability of graduates of environmental-technical fields of study of the Faculty of Science and Technology of the University of Opole (PL) and the Faculty of Science of the University of Hradec Kralove (CZ), when looking for employment in Czech and Polish companies. There is an increasing number of graduates of environmental-technical fields of study who do not work in their fields of study, despite the fact that these workers are missing from the labour market in both countries. The convergence of study programs took place in the form of mutual cross-border teaching with the creation of Czech-Polish teaching materials focused on professional terminology and through exchange four-day field trips and fortnightly and monthly curricular internships. A team of internship tutors in companies, future potential employers of students, was created, a questionnaire for evaluating student performance in soft and hard skills was optimised and verified as part of a pilot study. Both groups of PL and CZ students achieved quite comparable results. There are also no significant differences in the evaluation of individual students in soft and hard skills. However, the number of respondents (students) was limited by the financial resources of the PL-CZ project, which were reduced during the COVID pandemic. Only selected students with a strong interest in the field of study and gaining practical experience participated in the study. Therefore, the conclusions of the pilot study need to be verified on a larger sample of respondents.

Published: February 2025

The management of composting home bio-waste at the place of their formation leads to several benefits. Among them are: minimising the amount of waste sent to landfills, decreasing the costs associated with transporting them to disposal sites, and reducing the need for new facilities dedicated to this purpose. A further advantage of home composting is the better segregation of waste compared to industrial composting, there is less accidental contamination by plastic, glass, or metal waste, which is a key requirement for a proper biodegradation process. However, despite to many benefits of home composting, the method is still controversial. The first part of the paper briefly characterises the key parameters for an effective home composting process, i.e.: temperature, air porosity, oxygenation, and moisture content. It is also widely considered and discussed the problem of reasons why home composters do not reach the temperature values considered necessary for the sterilisation of waste. Potential needs to reach the same high temperatures in home composting as in industrial composting are also discussed. The next part of the paper presents some technical solutions currently used in home composters to improve the process of biodegradation of waste and to make them easier to use. The final section addresses the quality of home compost and the issues around correctly assessing its maturity and stability.

Authors: Prebilič Vladimir , Rebrica Patrik
Published: February 2025

Cyber warfare has opened up a new dimension of warfare in modern conflicts. The dangers are greater than ever as critical infrastructure, financial systems and personal data become targets on this digital battlefield. The aim of this work is to show the impact of cyber warfare through the example of the Russian-Ukrainian war. To understand the role of cyber in warfare it is necessary to understand Russian, Ukrainian and NATO cyber warfare doctrine, and utilisation of these on the battlefield. Understanding these tactics allows for better national defence of states, protection of civilian lives and ensuring the stability of the global digital infrastructure. Analysing the cyber dimension of this conflict helps to develop strategies to mitigate similar threats in future conflicts.
Growth response of Douglas fir to the first early and delayed thinning
Authors: Dušek David , Novák Jiří
Published: February 2025

Douglas fir (Pseudotsuga menziesii [Mirb.] Franco) is considered one of the most promising introduced tree species for use in forestry in Central Europe. The formation of vital and stable forest stands with a certain share of Douglas fir (DF) requires the application of appropriate silvicultural measures, such as thinning. The article evaluates the growth response of DF to the initial experimental thinning. Eight stands were analysed on nutrient-rich sites in the three forest vegetation zones (Querceto-Fagetum, Fagetum, Abieto-Fagetum). The analysis includes both stands dominated by DF and stands where DF is only interspersed. The thinning was applied when the dominant tree height ranged from 5 to 20 m. A dominant tree height of 10 m was used as the threshold to define well-timed thinning. The data were analysed using Bayesian hierarchical modelling, and generalized hierarchical models were employed. DF promising trees responded to early thinning with significant acceleration of radial growth, leading to improvements in height-to-diameter ratio (HDR) and crown ratio (CR) parameters. The response of DF promising trees to delayed thinning was negligible. Neither early nor delayed thinning had a detectable effect on height growth of the DF promising trees. The result confirms the necessity of initiating thinning for DF stands at the stage of thickets. The thinning should ideally begin when the dominant tree height is between 4 to 5 meters. At this stage, it is possible to positively influence diameter growth and mitigate the deterioration of individual tree stability as well as the stability of the whole stand.
The Curricula of Primary Education and Neoliberal Educational Policy in Greece : A Critical Analysis
Authors: Sounoglou Marina
Published: February 2025

The purpose of this article is to contribute to a critical approach to analysing the new curricula and to outline student-centric approaches through an examination of legislation on educational policy applied by the Greek government in the last five years. After twenty years from the last curricula (2003), the new curricula were published in a period when the government was introducing new legislation and promoting assessment in education. The curricula for primary education, according to the authors, focus on a student-centric approach but this is not confirmed in the content and objectives, as the analysis of the curricula in this article shows. The critical analysis in this article is conducted from the perspective of critical pedagogy and contributes to the highlights on the control mechanism and the neoconservative politics on education as a control mechanism.

Poor estrus detection is the greatest limiting factor for reproductive performance in dairy cows. The study aimed to compare the reproductive performance by assessing the fertility rate (FR) between cows inseminated after detected estrus and those inseminated after synchronized ovulation with the Short Synch protocol. A total of 138 primi- and multi-parous dairy cows from 5 dairy farms in North Macedonia were included in the study. At day 65±3 postpartum, an ovarian ultrasound examination was performed for presence of corpus luteum (CL), and body condition scoring (BCS) was made (scale from 1-emaciated to 5-obese). Cows with a CL (n=92) were submitted to two synchronization protocols and grouped accordingly: SPG (n=46) synchronized with a single PGF2α injection, and SSG (n=46) synchronized with a Short Sync protocol (PGF2α–24h–PGF2α–32h–GnRH–16h–TAI). Cows were followed up to the second insemination. Pregnancy diagnosis was done at d30 and d60 after each insemination. Eleven cows (n=11) from the SPG didn’t show estrus signs and were excluded from further analysis. Overall, a higher FR (p=0.0008) was observed in the SSG (71.74%, 33/46) compared to the SPG (34.29%, 12/35). Cows in the SSG with BCS>2.75 (76.19%, 16/21) had a higher FR (p=0.0016) than cows in the SPG with BCS>2.75. No differences were observed (p=0.1242) between both groups that had BCS≤2.75 (68.00%, 17/25; 43.75%, 7/16, respectively). Multiparous cows in the SSG had a higher FR (p=0.0021, 71.43%, 25/35) than their counterparts from the SPG (30.43%, 7/23). No significant differences were observed among the primiparous cows. The results indicate that Short Synch protocol might increase the fertility rate in dairy farms.
The Invisible Work of the Costume Performer
Authors: Smith Lorraine
Published: February 2025

In the field of costume performance, the power of costume to create and communicate meaning and metaphor and enhance performer embodiment and audience connection has been evidenced and commended. There has been an abundance of research from both designer and performer perspectives, with a focus on the evolving relationship between the body and the costume. However, does 21st-century progressive experimental costume performance, which may include the use of unconventional materials, have the potential to impact the labour of the performer? Costume can both reveal and hide the body, arguably making the work of the body visible and invisible. This research article builds on the paper presentation “The Invisible Work of the Costume Performer”, delivered at the NOFOD Conference 2024. It examines the potential for costume to conceal the cognitive, physical, and emotional labour of the performing body and the resulting impact this may have on the performer.

Building on the understanding of Western traditional approaches and hierarchies in performance making and the complex relationship between dancer/performer and pain, the performance projects PING (2014), PANG (2021), and You Can Take Me Home Toni (2023) are interrogated. From the perspective of the performer, and informed by discussions with designer Daphne Karstens, Lorraine Smith analyses and contextualises these projects through the lens of feminist concepts relating to invisible work and emotional management. The article concludes by identifying possible solutions for making visible the invisible labour of the performer in costume performance and for the management of this workload on the performer’s body.
Becoming Foreign to Oneself: Embodied Encounters with Patients’ Written Memories of Mental Hospitals
Authors: Heimonen Kirsi
Published: February 2025

This article focuses on the ways in which an artist-researcher has encountered an extensive archive comprising Finnish individuals’ written memories of mental hospitals through a corporeal approach. The process of reading these accounts and the making of a short film, titled Here. Somehow, based on selected excerpts from some patients’ and visitors’ writings and a site-specific choreographic process, forms the core around which insights spiral.

Attuning to the writings and physical sites through corporeality was enabled through the Skinner Releasing Technique (SRT), an embodied movement method. This article deliberates on the potential of corporeal practice, through movement, to transform, reveal, and mediate something that is ineffable. What does it mean to research hunches and fractures, to read, write and perform through one’s vulnerable corporeality – which is inscribed in and transformed by SRT – to the extent that one eventually becomes foreign to oneself? A phenomenological approach with an interest in affects and atmospheres offers one way to discuss this unexpected phenomenon arising out of an encounter with writings and the physical locations inseparable from them.
Chakras and Shingles—Historical Fragments of the Chakra System in Contemporary Yoga
Authors: Damkjær Camilla
Published: February 2025

After a few days with intense yoga training, curious red spots occurred on the back across my shoulder. Curiously, it appeared right after a period where I had been reading about the chakras. So I could not help noticing that the rash was on the left side of the back, right at the heart chakra.

With the global growth of postural yoga, various concepts connected to yoga have become more visible in the landscape of movement practices. One such concepts is the chakra system. However, it can be challenging for a practitioner to fully grasp the significance of the system in a given context. In this article, I explore how a complex inheritance of ideas related to the chakra system, rooted in different cultures and periods, continues to reappear in contemporary yoga.
Robust Adaptive Control of Dual Active Bridge DC-DC Converter with Constant Power Loading
Authors: Effah Emmanuel K. , Effah Francis B. , Okyere Philip Y. , Anto Emmanuel K.
Published: February 2025

The standard model reference adaptive control (MRAC) application to the Dual Active Bridge (DAB) converter has proven to achieve excellent dynamic and tracking responses under parametric uncertainty. However, it is sensitive to bounded non-parametric uncertainty caused by measurement noise and ripples in the output voltage produced in the electronic device. When left unchecked, it affects the system’s performance and may lead to instability. This paper investigates two robust modifications to the standard MRAC, namely the projection operator and dead zone techniques, to tackle the issue of the bounded noise to the dual active bridge with constant power loading (CPL). It further develops an improved form of the dead zone-based MRAC, which ensures better transient and steady-state output voltage when compared with the traditional dead-zone-based MRAC.
Competitive Vs. Recreational Sport: Examining the Link to Harmful Alcohol Drinking in Youth
Authors: Zenic Natasa , Kvesic Ivan , Gilic Barbara
Published: February 2025

Introduction.
Sports are frequently investigated in relation to alcohol consumption habits in adolescence, but few studies have reported various competitive- and recreational-sport factors as correlates of harmful alcohol consumption in youth. This cross-sectional study aimed to identify possible associations that may exist between sports factors and harmful drinking in adolescents, emphasizing the specific influence of participation in competitive and recreational sports.

Material and Methods.
The participants were 650 adolescents from Bosnia and Herzegovina (16-17 years of age, 313 females) who were tested for sociodemographic factors, competitive-sport factors, recreational-sport factors, physical activity levels (PALs), and outcome-alcohol drinking (obtained by Alcohol Use Disorders Identification Test – AUDIT). For the purpose of statistical analyses, the obtained AUDIT score was dichotomized (non-harmful vs. harmful drinking).

Results.
Harmful drinking was more common in males than in females (χ2 = 47.01, p < 0.001), and those adolescents who reported better competitive success in sports (χ2 = 41.81, p < 0.001). The PAL was greater in those males who did not report harmful drinking (t-test = 2.45, p < 0.05), with no significant difference in females or in the total sample. Logistic regressions were performed with sex as a confounding factor and revealed that competitive success in sports was significantly correlated with harmful drinking (OR = 1.32, 95% CI: 1.02-1.66, p < 0.05).

Conclusions.
This study highlighted the specific association between competitive sports success and harmful drinking in adolescents, indicating the need for a more detailed analysis of the background of the established association. Further analyses on the potential association between PAL and substance misuse in youth are warranted.

Authors: Kontic Dean , Rodek Jelena , Sekulic Damir
Published: February 2025

Introduction.
Adventure sport tourism (AST) and nautical sport tourism (NST) have some similarities but may attract different segments of tourists. The aim of this study was to evaluate and differentiate sociodemographic factors associated with participation in NST and AST.

Material and methods.
The participants were 678 tourists (34.11 ± 7.2 years of age) who were involved in NST (n = 311) and AST (n = 367) during the summer seasons of 2023 and 2024 in Croatia. The variables included sociodemographic factors (age, gender, education level, socioeconomic status, marital status, parenthood, urban/rural living community, and physical activity-lifestyle; all predictors), and participation in AST or NST (outcome).

Results.
Compared with participation in AST, older age (OR = 2.41, 95% CI: 2.00-2.80), male gender (OR = 2.11, 95% CI: 1.81-2.33), and better socioeconomic status (OR = 2.01, 95% CI: 1.55-2.56) were significantly associated with a greater likelihood of being involved in NST. Compared with NST, a higher education level was associated with involvement in AST (OR = 0.88, 95% CI: 0.77-0.98).

Conclusions.
By understanding the characteristics of the analyzed groups, tourism operators can better design experiences that meet the specific needs and expectations of their clientele.
Association of neutrophil-to-lymphocyte ratio and monocyte-tolymphocyte ratio with all-cause mortality in patients with ischemia and non-obstructive coronary arteries
Authors: Mihai Emilian Dumitru , Delcea Caterina , Buzea Adrian Cătălin , Dan Gheorghe-Andrei
Published: February 2025

Background

Ischemia with non-obstructive coronary arteries (INOCA) is a frequent coronary syndrome with important impact on morbimortality. Systemic inflammation, a key pathophysiological mechanism in its development, is reflected in diverse bio-markers, such as the neutrophil-to-lymphocyte ratio (NLR), monocyte-to-lymphocyte ratio (MLR) and platelet-to-lymphocyte ratio (PLR). In this retrospective observational study, we aimed to assess the value of NLR, MLR and PLR as predictors of all-cause long-term mortality in INOCA patients.

Methods

Acute/ chronic consecutive INOCA patients hospitalized from January 2014 to December 2019 were included, after excluding pulmonary hypertension, acute non-cardiac pathology, and in-hospital mortality. The primary endpoint was all-cause mortality.

Results

Our cohort included 238 INOCA patients (62.2% female, mean age 64.1±9.5 years). Of all patients, 14.3% reached the endpoint during the mean 5.8±1.1 years of follow-up. Age (OR=1.10, p<0.001), diabetes mellitus (OR 2.54, p=0.01), heart failure (OR=3.73, p=0.003), atrial fibrillation (OR=3.52, p=0.001), severe valve disease (OR=3.99, p=0.001), NT-proBNP (OR=3.28, p<0.001), 3rd tertile NLR (OR=4.33, p<0.001) and 3rd tertile MLR (OR=4.34, p<0.001) were mortality predictors, while the 3rd tertile PLR was not. In multivariable analysis the baseline prediction model included age (HR=1.12, p<0.001) and heart failure (HR=3.78, p<0.001). Adding NLR>2.99 (HR=4.58, p<0.001), MLR>0.36 (HR=4.74, p<0.001), or both increased the power of the predictive model from chi-square 33.00 to 51.08 (p<0.001).

Conclusions

In patients with acute or chronic INOCA, NLR and MLR were independently correlated with all-cause mortality. The most accurate mortality prediction model included NLR>2.99, MLR>0.36, age and the diagnosis of heart failure.
Correlations of vascular cognitive impairment with brain-derived neurotrophic factor and trace elements
Authors: Zhou Rong , Lei Chao , Zhi Haiyang
Published: February 2025

Background

Cognitive impairment has become one of the major public health problems due to population aging and the increased morbidity associated with stroke. In this study, we aimed to analyze the correlations of vascular cognitive impairment (VCI) with brain-derived neurotrophic factor (BDNF) and trace elements.

Methods

Between January 2022 and January 2024, a total of 206 subjects were included in the study, of which 103 were VCI patients treated in our hospital (a cognitive impairment group), and 103 were volunteers undergoing physical examination (a control group). Comparisons were conducted on the levels of BDNF and trace elements (Cu, Fe, Zn, Ca, Mg, Se, As, and Al) between the two groups.

Results

In comparison with the control group, the cognitive impairment group had significantly reduced levels of BDNF, Cu, Fe and Zn (p<0.05), a significantly raised Al level (p<0.05), and decreases in the total score of Mini-Mental State Examination (MMSE) and corrected total score of Montreal Cognitive Assessment (MoCA) (p<0.05). The total score of MMSE and corrected total score of MoCA were positively correlated with the levels of BDNF, Cu, Fe, and Zn (p<0.05) and negatively correlated with the Al level in both groups (p<0.05). BDNF <5.39 μg/L, Cu <10.87 μmol/L, Fe <5.97 μmol/L, Zn <77.32 μmol/L, and Al >0.72 μmol/L were risk factors for VCI.

Conclusions

VCI patients have significantly lower levels of BDNF and trace elements (Cu, Fe, and Zn) and a significantly higher Al level than those of healthy populations. Excessively low levels of BDNF and trace elements (Cu, Fe, and Zn) and an overly high level of harmful element Al are risk factors for VCI.
Factors affecting the development of green banks at commercial banks in Ho Chi Minh City
Authors: Tuan Nguyen Van
Published: February 2025

The banking sector plays a special intermediary role in providing financial support to various sectors of the economy. Therefore, by incorporating green standards into its lending decisions, the commercial banking system (CB) will promote economic development and help build a greener and cleaner world. In Vietnam, research on Green Banking is limited compared to many international investigations. Most of these studies focus on reports and presentations that review experiences from other countries. Therefore, there are still many gaps in theoretical and practical research on green banking in Vietnam, making this an area ripe for further quantitative exploration. Consequently, it is necessary to research both the theoretical and practical aspects of “green banking” and establish quantitative models to assess the impact on the development of green banking in Vietnam. The objective of this study is to find out the factors that can promote the development of green banking at commercial banks in Ho Chi Minh City in the coming time. By using EFA and regression model, the results show 07 factors, including: (1) Potential benefits; (2) Concern for the environment; (3) Pressure from stakeholders; (4) Green product development; (5) Banking technology; (6) Bank brand; (7) Banking policy have the main influence on the development of green banking at commercial banks in Ho Chi Minh City. From the research results, the author makes some recommendations to improve the development of green banking activities of commercial banks in Ho Chi Minh City.

Authors: Silva Aiana Rodrigues Leonel da , Carvalho Pamela Alves , Ribeiro Vinícius de Oliveira , Corrêa Nelison Ferreira
Published: February 2025

Objective: This study investigated the scientific production on Urban Parks in Permanent Preservation Areas (APPs), focusing on their multifunctionality in environmental conservation and ecological education.
 
Theoretical Framework: The study is based on the National Environmental Education Policy (Law nº 9.795/1999) and research highlighting Urban Parks as strategic spaces for environmental balance and collective awareness.
 
Method: A bibliometric analysis was conducted using the Scopus database, covering 562 documents published between 1979 and 2023. The VOSviewer software was used to identify co-authorship networks, keywords, and thematic patterns.
 
Results and Discussion: Urban Parks in APPs have great potential for sustainability and environmental education but are underutilized as pedagogical tools. Expanding the integration between conservation and education through public policies, experimental projects, and participatory management strategies is recommended. This study contributes to the formulation of guidelines to maximize the impact of these spaces on urban quality of life and environmental awareness.
 
Originality/Value: This study provides a comprehensive overview of the scientific landscape on Urban Parks in APPs, identifying key trends, gaps, and opportunities for future research. It highlights the underexplored potential of these spaces as tools for environmental education and suggests strategic actions to enhance their multifunctionality. The findings offer valuable insights for researchers, policymakers, and practitioners in urban planning and environmental management.
Storage of Biogas and its Technologies: a Review
Authors: Orth Jaqueline Tomasini , Frigo Jiam Pires , Furtado Andreia Cristina
Published: February 2025

Objective: Carry out a systematic literature review to identify the storage technologies available for biogas, assessing the characteristics of storage technologies with respect to the type of organic material used for anaerobic digestion, and whether there are studies regarding the storage of biogas in natura.
 
Theoretical Reference: This study was drawn up from a systematic literature review on the technologies of storage of biogas, the main characteristics of such technologies, considering the biomass used, and if there are studies referring to the storage of biogas in natura, showing the main tools available, as well as the main works published in recent years.
 
Method: The database platforms CAPES, Science Direct and Scielo were used to select the articles. Only articles in the Portuguese, English and Spanish languages were selected, and course completion papers, dissertations and theses were excluded. The keywords used were "storage" and "biogas", "storage biogas". Only articles published in the last 10 years were considered, between the years 2014 and 2024, searches were carried out in the month of October 2024. The exclusion criteria were the storage of biogas in natura and purified.
 
Results and Discussion: After the research it was found that there is still a considerable shortage in researches and methods tested for the storage of this material, however the studies already published bring clarity and basis for the deepening of the researches.
 
Research Implications: A systematic literature review on such an important topic can contribute to the search for relevant work that addresses biogas storage. The technologies already studied show that biogas, whether natural or purified, can have a wide range of applications in various areas, contributing to the preservation of natural resources and reducing the energy load from non-renewable sources.
 
Originality/Value: This study contributes to the literature by identifying and discussing the work already done in the field of biogas storage. The relevance and value of this research is evidenced, because this material has an important renewable energy value, which contributes significantly with the preservation of natural resources, the reduction of pollution, and consequently bringing economic and financial return to the community in general.

Authors: Mariano-da-Silva Samuel , Mottin Fernanda Macetti , Ducatti Rafael Dal Bosco , Tramontin Marco Aurélio , Tironi Siumar Pedro , Radünz André Luiz
Published: February 2025

Objective: The objective of this study was to evaluate the effects of different copper concentrations on the germination and seedling development of canola.
 
Theoretical Framework: Soil contamination by copper can impact the production and quality of canola, making it essential to understand these aspects to ensure sustainable crop management.
 
Method: The experiment was conducted as a randomized complete block design with crossed classification and plots subdivided in time. Each treatment was replicated four times. The main factor (plot) consisted of 4 levels (0, 200, 400, and 800 mg L⁻¹) of copper contamination, and the secondary factor (subplot) consisted of 3 evaluation days (fifth, sixth, and seventh). The seeds corresponding to each treatment were maintained in a germinator at a temperature of 25±2 ºC and a 24-hour photoperiod. Evaluations regarding seed germination, shoot/root length, and the dry weight of seedlings were conducted between the fifth and seventh days after sowing. Analysis of variance was used to evaluate the variables and, when means were significantly different, multiple comparison test (Tukey's HSD) or regression analysis were used, both at a 95% confidence level.
 
Results and Discussion: Different copper concentrations negatively affected the germination rate, root development, shoot growth, and seedling dry mass, leading to an increase in the rate of abnormal seedlings at intermediate copper concentrations.
 
Research Implications: The results raise the importance of understanding the type of agricultural fertilizer being used in an area so as to prevent toxic copper levels to be built up in soils.
 
Originality/Value: Despite a considerable number of studies on the cytotoxic effects and stress mechanisms induced by heavy metals in biological systems, data regarding the effects of this metal on the germination of cultivated plants remain scarce and unclear. There is still a need to clarify many metabolic aspects, justifying the use of canola and copper for furthering the current knowledge on this subject.
In situ Methanation on Mars: A Process Concept Study on the Impact of H2/CO2 and Recycle Ratio
Authors: Braun Franz , Nagel Thomas-Oliver , Prinz Samuel , Friedland Jens , Güttel Robert
Published: February 2025

For planning return missions from Mars, considerations about the supply of rocket fuel are crucial. Since transportation of propellant from Earth and storage at Mars is costly and energy intensive, in situ resource utilization (ISRU) for methane production on Mars presents a promising solution. The major challenge is to identify a simple and robust production process, which provides the required purity of the propellant. In this study, we compare two different process concepts, with and without recycle, under realistic operating conditions using thermodynamic modelling and simulation. The H2/CO2 feed ratio is crucial to achieve sufficiently high methane selectivity and thereby reduce the effort in product gas cleaning and the overall process complexity. At the same time, recycling unreacted reactants reduces resource consumption, which is preferable for ISRU scenarios. Hence, our study provides a basis for more detailed process design using kinetic information on the involved process steps.

Authors: López Olmedo Yesenia G. , Sánchez-Medina Patricia S. , De Yta-Castillo Diana
Published: February 2025

El objetivo de este trabajo fue analizar la relación del recurso humano (RH) y la estrategia de mercadotecnia verde (EMV) con el desempeño económico (DE) y el desempeño social (DS) de Oaxaca, México. Se creó un modelo de investigación de acuerdo con la teoría basada en los recursos y capacidades (TRC). Para analizar la relación entre variables, se aplicaron cuestionarios de manera personal y las hipótesis fueron probadas con un modelo de ecuaciones estructurales a través de la técnica Partial Least Squares (PLS) con el uso del software Smart PLS 4.0. Se hallaron relaciones positivas y significativas entre el RH, la EMV y el DE y DS del sector hotelero de Oaxaca. La limitación del estudio radica en que se trató de una muestra de únicamente 157 hoteles de un estado de la República. El valor de la investigación se halla en que intenta examinar el DE y DS en el contexto oaxaqueño, poniendo especial énfasis en la identificación y comprensión de los factores que explican el DS. Se concluye que el RH y la EMV juegan un papel importante en obtener mejores desempeños económico y social en la muestra de hoteles analizada y, que a la luz del contexto de post-pandemia, los negocios hoteleros pueden echar mano de estos recursos y estrategias para alcanzar mejores resultados financieros, comerciales y sociales.

Esta investigación analiza la influencia de las motivaciones hedónicas, utilitarias y ecológicas en la intención de compra de ropa sustentable entre millennials mexicanos. Se utiliza una investigación cuantitativa, no experimental, explicativa y transversal a 383 participantes. Los resultados indican un impacto positivo y significativo de la motivación utilitaria y ecológica sobre la intención de compra de moda sustentable, siendo la motivación utilitaria la motivación que más influye en los consumidores. Sin embargo, la motivación hedónica no impacta en la intención de compra. Dado que se utiliza un muestreo no probabilístico, los resultados no pueden ser generalizados para la población millennial mexicana, si bien contribuyen a la comprensión de la naturaleza de los aspectos que impulsan la intención de comportamientos de compra ecológicos.

A partir del hecho jurídico de que cualquier empresa que no inscriba en tiempo y forma a su personal ante el IMSS, generaría un Capital Constitutivo en caso de que un trabajador sufra un Riesgo de Trabajo y que el costo financiero puede llegar a ser extraordinariamente alto, el objetivo del presente artículo es mostrar qué tan altos son estos costos en un accidente. Todo esto para sensibilizar al sector patronal y que no incurra en conductas omisas y riesgosas, además que comprenda el beneficio social de que, el otorgamiento de la seguridad social influye en la generación de nuevas plazas y en la conservación de las existentes, y también brinda la oportunidad al trabajador de, al final de su vida laboral, disfrutar de seguridad económica y no ser una carga para su familia y la sociedad.

Published: February 2025

Actualmente el liderazgo es una tendencia mundial que ha impactado los sistemas operativos, financieros y productivos de todo tipo de organización, en este contexto, destaca la importancia de contar con un modelo de liderazgo que brinde los elementos para conformar un perfil de líder, que guíe los procesos humanos y la integración de equipos de trabajo. Bajo esta tesitura, en  Latinoamérica se aprecia que las organizaciones aplican modelos de liderazgo extranjeros que no responden totalmente a las características y cultura de la región, así mismo se observa que un alto porcentaje de las compañías utilizan el modelo autoritario (Stakeholder) para el desarrollo de sus funciones y actividades dentro de los procesos productivos.Con el propósito de contrarrestar esta tendencia, se propone desarrollar un perfil del líder latinoamericano que combine el interés por la tarea y por el individuo (Multistakeholder) en busca de un incremento de la productividad y del bienestar individual. En estas circunstancias, se propone la implementación del modelo de Liderazgo Empático y la aplicación de sus principios, los cuales son la base del perfil, además de  contemplar la cultura, costumbres y creencias de la región.
Coaching: conciliación de vida laboral-personal (WLB)
Authors: Musicco Ginevra
Published: February 2025

Este artículo presenta una investigación de carácter social y humanista que trata de demostrar la utilidad de la aplicación de las herramientas de coaching en la consecución de un equilibrio vida laboral-personal. La metodología es cualitativa como resultado de la síntesis entre la deducción y la inducción, llevándose a cabo en menor medida un enfoque cuantitativo. Se continúa con la identificación de los principales problemas y los posibles grupos sociales receptores de la aplicación de las herramientas de coaching para lograr un equilibrio entre la vida laboral-personal, abarcando todas las categorías sociales, es decir, los padres de familia y no sólo las madres trabajadoras, con especial consideración a los 'single'. Finalmente, se perfilan las mejoras que experimentaría la sociedad en su conjunto y los individuos al sentirse realizados tanto personal como laboralmente y se deja una puerta abierta al cambio de mentalidad en los líderes para conseguir una empresa más humanizada, proponiendo la inclusión de este tipo de políticas como elemento clave dentro de la Responsabilidad Social Corporativa de una empresa.

A worldwide indication of the amount of water used in the manufacturing cycle of commodities is called the “Water Footprint.” The entire amount of freshwater used or contaminated throughout a commodity’s manufacturing is known as its “water footprint.” Water consumption mostly refers to the amount of water that plants need during the growth season (green and blue water), whereas water pollution (gray water) is primarily caused by fertilizer seeping from the field. To investigate the effects of varying irrigation and nitrogen dosage levels on vegetative growth characteristics, yield parameters, and chemical contents, an experiment was conducted on garlic plants during the two winter seasons of 2020–2021 and 2021–2022, at the Central Laboratory for Agricultural Climate (CLAC) research site, Dokki, Giza, Egypt. To investigate the effects of varying irrigation levels and nitrogen doses on vegetative growth characteristics, yield parameters, and chemical contents of garlic. The nitrous oxide (N2O) and water footprint (WFP) emissions were estimated using the collected data. Two elements make up the treatments: three main plots with irrigation levels of 80, 100, and 120% of the required water, and three subplots with nitrogen levels of 60, 80, and 100 kg doses, each three duplicated in a split-plot design. The findings demonstrated that under irrigation, the highest vegetative growth parameters, yield parameters, and chemical composition of leaves were observed. The results demonstrated that, at an irrigation level of 120% of the water requirements and 100 kg of nitrogen dose for the garlic plant, the highest vegetative growth characteristics, yield parameters, and chemical contents of leaves were recorded. The relationship between nitrogen doses and irrigation levels reveals that, when combined, 120% irrigation levels and 100 kg of nitrogen dose produced high yield parameters, vegetative growth characteristics, and chemical content in the leaves; this was followed by 100% irrigation levels and 100 kg of nitrogen dose with notable differences between the two. In all measurements, the combination of 80% irrigation levels and a 60kg nitrogen injection yielded the lowest value. Under 120% irrigation and 60 kg of nitrogen fertilizer, the water footprint for the output of fresh and cured garlic was higher, measuring 628 m3/ton and 959 m3/ton, respectively. The maximum emission of N2O with 100 kg of nitrogen and an irrigation level of 80%, the highest N2O emission value for cured garlic yield, was reported at 0.283 kg N2O per ton of cured garlic output, or 84.5 kg CO2/ton. With 100 kg of nitrogen and an irrigation level of 80%, the greatest N2O emission value for fresh garlic output was reported at 0.190 kg N2O per ton, or 56.7 kg CO2/ton.

The primary objective of this research was to compare the utilization of ITKs across five specific upazila (Chitalmari of Bagerhat district, Paikgacha of Khulna district, Kotalipara of Gopalganj district, Shyamnagar of Satkhira district and Jashore Sadar of Jashore district). Data were collected through personal interviews conducted with a total of 500 (100 respondents per upazila) respondents, encompassing four distinct categories (crop, fisheries, livestock and weather related ITKs). Results revealed that crop related ITKs were used most by the respondents at an average of 67.8%, while fisheries related ITKs obtained the lowest level of usage. Among the five upazila, Jashore Sadar exhibited the highest (67.8%) utilization of crop related ITKs whereas Kotalipara showed the least (50.8%) usage. In terms of fisheries related ITKs, Shyamnagar upazila exhibited the highest utilization rate (41.7%), while the lowest (21.3%) usage was found in Kotalipara. Respondents of Chitalmari upazila found the maximum (42%) usage of livestock related ITKs contrasting with Kotalipara, which showed the minimum (36.7%) usage. Additionally, weather-related ITKs were utilized in Jashore Sadar upazila was maximum (75.3%), while least (47%) usage obtained in Chitalmari. Significant disparities were observed among the upazila concerning the categorization of adapters. Among five upazila, there had been a notable prevalence of a high rate of Early Adopters, while exclusively in Jashore, the dominance laid in the high rate of the Early Majority. This research sketches a clear finding that many respondents were primarily clustered within the medium-use category of ITKs, closely followed by those in the low-use category.
O universal e o exótico na recepção de reescritas e traduções de Grande Sertão: Veredas na Alemanha
Authors: Cordeiro Pinto Otavio , Dias Carneiro Teresa
Published: February 2025

O presente artigo pretende investigar alguns dos processos de reescrita e retradução pelos quais o romance de João Guimarães Rosa, Grande Sertão: Veredas (1956), passou e passa, com foco na recepção das traduções do livro para a língua alemã e em declarações de atores envolvidos nos diferentes processos de reescrita analisados. A análise será feita apoiando-se nas elaborações sobre reescrita de André Lefevere (1992) e de retradução de Álvaro Faleiros e Thiago Mattos (2017). O estudo parte da tese de Grande Sertão: Veredas (1956) como reescrita crítica de Os Sertões (1902), de Euclides da Cunha, pela primeira tradução para o alemão, Grande Sertão: Roman (1964), feita por Curt Meyer-Clason, e pelo projeto de retradução — ainda não finalizado — de Berthold Zilly. Durante esse percurso, propõe-se uma análise das reescritas de Grande Sertão: Veredas como manipulações que podem motivar leituras da obra a partir de um ponto de vista mais exótico ou universal. O estudo se inicia no olhar mais exotizante do sertão e de seu povo, presente em Os Sertões; parte para a dimensão mais universal conferida ao sertão em Grande Sertão: Veredas; até a primeira tradução de Meyer-Clason, vista novamente pendendo ao exotismo; e conclui na retradução de Zilly, que já se desenha, mesmo antes de sua publicação, como uma reescrita que se propõe mais universal.
