Published: April 2024

Este artigo teve como objetivo investigar a produção de sentidos e (in)tensões do Currículo da Educação Infantil, construindo um panorama histórico acerca das políticas educacionais para esta etapa de ensino no Brasil, no período da década de 1990 até os anos 2023.  Adotando a abordagem qualitativa, fundamentada em Moreira (2009), que descreve que o percurso da pesquisa é flexível e se articula aos interesses e na interpretação de situações de investigação. Para a coleta de dados utilizamos a entrevista semiestruturada, realizada em agosto de 2023. O campo empírico da coleta de dados foram, três escolas municipais, sendo duas de Nazaré da Mata e uma de Carpina, ambas de Pernambuco. Para a análise dos dados utilizamos a abordagem Transversal de Escuta Sensível de René Barbie e a análise do conteúdo temático categorial de Bardin (2011). Como resultados apontamos conhecer o currículo da educação infantil é fundamental para a compreensão de educação, criança, infância, brincar e as (in)tensões que se reverberam no currículo, sobretudo porque o/a professor/a é quem está na sala de aula realizando intervenções e trabalhando diretamente com a criança dando significado as aprendizagens.
Cambios de espacios educativos: nexos o rupturas del estudiante universitario
Authors: Cadavid Marín Angela María , Calderón González Marco Felipe
Published: April 2024

Se presentan los resultados de una investigación cualitativa, cuyo objetivo fue comprender los nexos o rupturas que experimentan algunos estudiantes universitarios en relación con los cambios de espacios educativos, a partir de su visión de realidad con el fin de visibilizar su realidad contextual. Para ello, el método elegido fue el biográfico narrativo, donde a partir de relatos de vida se pudo evidenciar que los nexos o rupturas que experimentan los estudiantes a partir de su visión de realidad, se dan en la dinámica cotidiana en relación con dichos espacios educativos, lo que lleva al rompimiento, a la acomodación y a la construcción de una  nueva visión de la cotidianidad, a medida que los estudiantes hacen el cambio rural-local-urbano. De lo cual se desprende que no hay una real ruptura con lo que arraiga al estudiante, por tanto, es necesario enfocar la educación en el campo, desde los cambios de vida y no de ubicación, donde se atienda a lo específico de cada uno de ellos, lo que incluye fundamentalmente el acompañamiento y entendimiento de la vida en el hogar, el pueblo y la ciudad (y la visión de esta vida) desde el estudiante mismo.

En cuanto a la literacidad crítica dentro de un perspectiva evolucionista e intencionada, pasaron de la actitud de alerta, al ciudadano crítico y finalmente, al cambio social.
Prácticas espirituales: ritual, armonización y círculos de la palabra, una propuesta curricular desde la educación propia
Authors: Zamora González Maria Janed , Cano-Echeverry Sebastián
Published: April 2024

For indigenous communities, one of the pillars of their own education is spirituality, understood as the harmonious human-nature relationship that is currently fractured and oriented towards only religious or only indigenous tendencies, ignoring its true inclusive, non-discriminatory value. Consequently, it is necessary to understand the configured meanings of spiritual practices: ritual, harmonization and circles of the word, to reconfigure the curricular frameworks of educational institutions. This qualitative research reflects on the importance of articulating spirituality to the teaching and learning process, and its main objectives are to characterize, identify and reconfigure spiritual practices as a proposal for self-education with a participatory action research (PAR) approach. It is contrasted with authors and the voices of the researcher and those investigated; where this category emerges: “the warp of spirituality, weaving education.” It is concluded that spirituality advocates all life processes and must be managed transversally in educational and curricular terms.
Effects of dietary soybean meal levels on reproduction parameters, the growth and gonad, gut, hepatopancreas histology of female African Cichlids Pseudotropheus socolofi
Authors: Pazar Mehmet , Bahadır Koca Seval , Özmen Özlem
Published: April 2024

This study was conducted to determine the effect of different soybean meal dietary supplementation levels on the growth, reproductive parameters, gonad, intestine and hepatopancreas histology of Pseudotropheus socolofi. Experimental groups were hand-fed to satiety with diets supplemented with soybean meal at levels of 3, 16, 27, 35, and 44% twice daily for 90 days. The results of this study showed that specific growth rate, weight gain, and survival rate were not affected by dietary soy proportions (P > 0.05). The worst FCR and final weight were found in those fed the diet containing 44% soy (P < 0.05). In female reproductive parameters, there was no significant difference between the groups in fertilization rate, egg production, hatching rate, egg diameter, gonadosomatic index and broodstock ovulation percentage (P > 0.05). However, due to pathological examinations in female individuals, a significant decrease was observed in the number of mature oocytes in the ovaries and goblet cells in the intestines with increasing soy levels in the diet (P < 0.05). As a result, using soybean meal up to 35% did not negatively affect growth. However, adding 44% soybean meal to diets caused histopathologically serious inflammatory reactions and decreased growth.
Student Motivation: Barriers and Incentives for Agency
Authors: Dobryakova Maria S. , Yurchenko Olesya V.
Published: April 2024

Our starting point was the often-overlooked understanding that motivation problems aren't a diagnosis but a symptom. They indicate the actual issue - an environment insufficient for fulfilling autonomy needs, which often escapes the attention of teachers, parents, and even researchers. Our goal was to develop a framework for exploring the main characteristics of a schoolchild's educational environment to identify the source of motivation problems. To do this, we combined aspects of the self-determination theory of E. Deci and R. Ryan with B. Bernstein's framing theory.
The self-determination theory helps to consider human motivation from a psychological point of view, while B. Bernstein's framing theory opens a sociological perspective. Including Bernstein's ideas enriches the motivation analysis, highlighting sociological aspects that are not fully accounted for in the self-determination theory. The result is more comprehensive and, at the same time, more "visible" and easier to operationalize in the context of formal school or home education.
Telework and bipolar disorder
Authors: Michel Bourin
Published: April 2024

Telework developed considerably during and after the COVID-19 pandemic. It seems interesting to evaluate the consequences of the use of teleworking in the population of bipolar patients. Increasingly accessible thanks to new technological and digital tools, it is however losing notoriety, because it presents some disadvantages, both for employees and for their employers. Yet, one of the essential benefits for bipolar people seems to be working at times when bipolar people are most productive due to their sleep/wake cycle for example.
Sexual Networks’ role in high STI Rates among minority populations
Authors: Kristine Shields
Published: April 2024

The stubbornly high and unequally distributed rates of sexually transmitted infections have confounded sociologists for decades. Why would STIs afflict minority populations at higher rates than majority populations? There was no biological rationale. Only knowledge of causation could hope to mitigate the discrepancy and provide pathways to prevention and cure. Late in the twentieth century, spurred by the AIDS crisis, the scrutiny of sexual behavior met up with the social determinants of health, resulting in the concepts of sexual networks and concurrency. This paper explores how these ideas have helped us understand, explain, and intervene in the unacceptably high and disproportionately distributed STI epidemic.
La profilassi antibiotica dell’endocardite infettiva nelle procedure odontoiatriche: reazioni avverse
Authors: Crociani Paolo
Published: April 2024

La profilassi antibiotica dell’endocardite infettiva in occasione di procedure odontoiatriche invasive è raramente seguita da reazioni avverse gravi. In Inghilterra nel periodo 2004-2014 non furono segnalati eventi avversi mortali, mentre furono segnalati 22,62 eventi avversi non mortali per milione di prescrizioni di amoxicillina; furono segnalate 13,6 reazioni avverse mortali e 141,1 reazioni avverse non mortali per milione di prescrizioni di clindamicina. In Francia nel periodo 1985-2015 vennero segnalati 17 casi di reazione anafilattica non mortale all’amoxicillina; non furono segnalati casi di anafilassi o di infezione da Clostridioides difficile dopo somministrazione di clindamicina. Negli Stati Uniti d’America nel periodo 2011-2015 furono segnalati 5 casi di anafilassi e 14 casi di infezione da Clostridioides difficile, il cui esito non è noto. Se vengono riferiti effetti collaterali in occasione di precedenti assunzioni di amoxicillina, è possibile valutare il rischio di reazione allergica mediante cutireazione con derivati della penicillina e somministrazione di dosi crescenti di amoxicillina. Prima di somministrare un macrolide, può essere prudente accertare se il paziente presenti un allungamento dell’intervallo QT o assuma farmaci che possano causarlo. È consigliabile raccomandare di riferire al medico sintomi gastrointestinali che si manifestino nelle settimane successive alla somministrazione della profilassi antibiotica dell’endocardite infettiva.

Published: April 2024

Le tecniche di riparazione e sostituzione valvolare chirurgiche e percutanee hanno conosciuto un periodo di importante evoluzione e raffinazione, con un numero sempre maggiore di pazienti trattati con successo. Tuttavia ancora oggi tra le complicanze post-operatorie si annovera una percentuale variabile dal 2 al 15% di incidenza di leak periprotesici sia per interventi su valvulopatia aortica che mitralica (le principali nella popolazione generale). L’impatto clinico a breve e lungo termine dei leak peri-protesici è oggetto di dibattito così come la loro valutazione invasiva e non. Le opzioni di trattamento in pazienti selezionati possono essere effettuate sia chirurgicamente che transcatetere, con percentuali variabili di successo e di impatto prognostico. In questo focus-on si cercherà di riassumere le più recenti e rilevanti evidenze sulla valutazione del leak, sul loro significato clinico e sulle diverse opzioni di trattamento, analizzandone indicazioni e outcomes a lungo termine.

An approach to simulation modeling and optimization of traffic flows in local sections of the street road network using AnyLogic and heuristic algorithms is presented. A feature of this approach is the use of agent-based (ABM) and discrete-event simulation methods supported in the AnyLogic system. An original swarm optimization algorithm (PSO) is proposed, modified for the problem of optimizing road traffic on a real section of the road (near the Yugo-Zapadnaya metro station in Moscow). Numerical experiments were performed to confirm the possibility of optimizing the duration of traffic light phases in order to minimize the average travel time of vehicles on a simulated section of the street road network.

In present work peculiarities of electron transport with transition from quantum wires with smaller cross sections to quantum wires with larger cross sections are studied. Electron transition probabilities through corresponding contact regions of such quantum wires are calculated as functions of charge carrier kinetic energy and quantum wire cross sections ratio. Peculiarities of electron pass through the defects in quantum wires in the form of rectangular grooves and steps are also studied. Electron transition probabilities through the defect regions are calculated as functions of electron kinetic energy and geometry and size of the defects. Probability density distributions of electron detection in different regions of simulated structures have been calculated.

Survey is popularly used in conducting research. With the recent rise of big data, survey scholars are calling for integrating data mining methods into traditional survey studies to refine theories and exploit insights in new contexts. However, the integration of survey and data mining techniques to refine theories is still underdeveloped, and the importance of addressing the interpretability and non-interpretability of various data mining algorithms is greatly needed. To bridge these gaps, we integrate data mining predictions into a traditional survey-based study, demonstrating interpretable and uninterpretable algorithms that predict an individual's willingness to pay for e-learning markets. We provide a step-by-step guideline, from goal definition and data preparation to variable choice, prediction accuracy, and theory refinement, to assist survey scholars in combining the two research methods to enhance a well-regarded theory, the Technology Adoption Model (TAM). We discuss the trade-offs that survey scholars may encounter when combining the two methods in refining theories and suggest how they might overcome these inherent difficulties. By demonstrating a theory’s potential for improving prediction accuracy and exemplifying how data mining results can refine theories, our study contributes to survey scholars on how to refine theories to increase theoretical contributions with new data mining methods.

Federated Learning (FL) is a transformative, distributive computational approach that revolutionizes decision-making capabilities through decentralized data computation. Despite notable operational advantages stemming from FL implementation, the optimal selection of methods from the existing literature and the design of resource-efficient and model trained solutions continue to evolve. This research presents a comprehensive systematic literature review, offering insights into the current state of FL advancements. Our study amalgamates various pivotal components influencing FL performance and elucidates their associations, fostering sustainable competitiveness. To evaluate the progress in this domain, we adopt the Theory-Context-Characteristics-Methodology (TCCM) framework, which systematically assesses the theories, contextual factors, characteristics, and methodologies employed in FL research. We identify distinct methods which have been combined with the FL algorithm by the organization and its host, or in collaboration to reach goals and support efficient decision-making. We complement the findings of our literature review by providing a synthesis of theories about FL for informed decision-making while taking into consideration the distinctive capabilities and affordances it offers.

Several governments are leveraging social media for political communication. While the phenomenon of gate-keeping in filtering information through social media has received attention from scholars, the role of diverse meso-entities (comprising pressure groups, experts, and professionals) in influencing digital political communication remains under-studied. We explore the trend in communicating a specific program for electoral gains and identify different types of entities that reshape and disseminate political communication on Twitter, with an illustration of the launch of the public health insurance program in India. We find the significant presence of meso-level entities that played an instrumental role in influencing political communication from macro to microlevel entities through the digital platform. We extend the Jungherr, Schoen, and Jürgens (2016) framework of macro to micro-level political communication in social media by recommending a few propositions to be tested in future studies. Further, this study also contributes to information diffusion theory by explicating the role of various information intermediaries in influencing information flow from macro to micro users on social media platforms.

Heartbeat disorders are considered one of the main maladies that cause mortality. Therefore, their precocious diagnosis via ECG signal is critical for introducing prompt therapy. The advanced automatic classification of ECG signals has the potential to save cardiologists a tremendous amount of time while simultaneously decreasing the chance of misdiagnosis. The dilemma of massive parameters is troubling the current methods of ECG signal classification. Most recent methods exhibit inadequate performance for diagnosing ECG signals in the inter-patient mode. In an attempt to deal with the above limitations, this study offers an innovative, efficient, and end-to-end model. The suggested model uses the optimized transformer framework to classify the heartbeats according to the "Association for the Advancement of Medical Instrumentation, AAMI," and obeys the inter-patient setting. We constructed an efficient architecture called the optimized network to substitute the Self Attention Unit (SAU) in the encoder part of the transformer model. The suggested model, which includes an optimized network, outperforms the SAU-based transformer model and requires fewer computations. A robust embedding architecture based on a Convolutional Neural Network (CNN) with a Squeeze and Excitation (SE) network-based attention scheme that has been used for weighting the Local Heartbeat Shape Pattern (LHSP) features is presented. The introduced model exceeds the state-of-the-art. An extensive test has been done to compare the achievements of the suggested model with those of the cardiologists. The results proved the closeness of their performances.

Исследуется поглощение электромагнитного излучения свободным электронным газом, взаимодействующим с колебаниями решетки, в сверхрешетке квантовых точек. Предполагается, что электронный газ в сверхрешетке квантовых точек ограничен анизотропным параболическим потенциалом. Поглощение света свободными носителями при участии фононов рассчитывается во втором порядке теории возмущения. При вычислении коэффициента поглощения используются матричные элементы электрон-фотонного и электрон-фононного взаимодействий электрона (с полярными и неполярными оптическими фононами). При рассеянии электронов на полярных оптических фононах возможны три следующих перехода: (1) переход между размерными подуровнями только в х-направлении, (2) переход между размерными подуровнями только в y-направлении, (3) переход между размерными подуровнями как в x-, так и y-направлениях. Показано, что для рассеяния электрона на неполярных оптических фононах возможен только один переход - переход, обусловленный размерными подуровнями как для x-, так и для y-направлений.

Published: April 2024

Since the enactment of the current Criminal Procedure Code of the Russian Federation, the effectiveness of investigating cases involving minors has gained considerable attention. This heightened relevance stems from the provisions of the 2001 Criminal Procedure Code, which expanded the scope of preliminary investigations for such cases to include inquiries, sparking lively debates among scholars. Currently, the question of determining jurisdiction for criminal cases involving juvenile offenders remains both theoretically and practically significant, necessitating further study. This article delves into the historical evolution of the investigation of criminal cases involving minors and examines its current state.
Exploring the Dualism of Law and its Ramification: а Focus on Arctic Subsoil Exploitation
Authors: Степанов Олег A.
Published: April 2024

This article analyzes the problem of legal dualism and its ramifications, particularly considering the increased interest of states in exploiting the Arctic subsoil. This article examines the unilateral announcement of the United States government to extend the continental shelf off the coast of Alaska in the Arctic and the Bering Sea, citing provisions from the Russian-American Convention of March 29, 1867, as a prime example of legal dualism. Within this framework, seemingly contradictory concepts are treated as law. The procedural aspects of the treaty that transferred Alaska to the physical administration of the U.S. are analyzed alongside the reasons for the absence of an established border between the U.S. and the Russian Federation. The legal ambiguity surrounding the 1867 treaty, which remains incompletely formalized and thus generates corresponding consequences, is considered. Additionally, this article analyzes actions by the U.S. administration in response to Texas’ claims of secession from the U.S., rooted in differing local and federal interpretations of the U.S. Constitution, as well as the implications of the temporary ban on issuing new export permits for U.S. liquefied natural gas. A solution is proposed to address the adverse effects of legal dualism in this domain by using digital financial assets.

Published: April 2024

Introduction Treatment methods for late stages of ankle osteoarthritis are varied, but the issue of assessing the long-term results of various fixation methods has not yet been studied, and this issue is of great importance in clinical practice.

Purpose To compare the effectiveness of the fixation methods commonly used for ankle arthrodesis in patients with advanced ankle osteoarthritis.

Materials and methods Eighty-two patients with advanced ankle osteoarthritis were treated with ankle fusion between 2019 and 2023 at three major medical institutions. All patients underwent 12-month follow-ups. The patients were divided into four groups depending on the method of surgical fixation of bone fragments.

Results Most patients showed a significant improvement in the function and a decrease in pain intensity after the arthrodesis operation. The comparison of the effectiveness of various surgical fixation methods found that external apparatus screw fixation is characterized by lower blood loss and a relatively short duration of the operation. Plate and screw fixation resulted in higher AOFAS and VAS scores at 3 months postoperatively. However, by the 12th month after surgery, the differences in these two indicators were insignificant.

Discussion Despite the various complications that occur in ankle arthrodesis, it remains effective for  most patients. Among them, the Ilizarov apparatus is more suitable for patients with compromised conditions in the surgical area. Each method of surgical fixation has its own advantages and shortcomings, but the difference in long-term effectiveness is small.

Conclusion Ankle arthrodesis is an effective treatment for advanced ankle osteoarthritis. The choice of surgical method is still subject to the principle of individual approach.

AIM: To explore the effects of hepatocyte growth factor (HGF) on retinal pigment epithelium (RPE) cell behaviors.
METHODS: The human adult retinal pigment epithelial cell line-19 (ARPE-19) were treated by HGF or mesenchymal-epithelial transition factor (MET) inhibitor SU11274 in vitro. Cell viability was detected by a Cell Counting Kit-8 assay. Cell proliferation and motility was detected by a bromodeoxyuridine incorporation assay and a wound healing assay, respectively. The expression levels of MET, phosphorylated MET, protein kinase B (AKT), and phosphorylated AKT proteins were determined by Western blot assay. The MET and phosphorylated MET proteins were also determined by immunofluorescence assay.
RESULTS: HGF increased ARPE-19 cells’ viability, proliferation and migration, and induced an increase of phosphorylated MET and phosphorylated AKT proteins. SU11274 significantly reduced cell viability, proliferation, and migration and decreased the expression of MET and AKT proteins. SU11274 suppressed HGF-induced increase of viability, proliferation, and migration in ARPE-19 cells. Additionally, SU11274 also blocked HGF-induced phosphorylation of MET and AKT proteins.
CONCLUSION: HGF enhances cellular viability, proliferation, and migration in RPE cells through the MET/AKT signaling pathway, whereas this enhancement is suppressed by the MET inhibitor SU11274. HGF-induced MET/AKT signaling might be a vital contributor of RPE cells survival.

AIM: To investigate systemic immune-inflammation index (SII), neutrophil-to-lymphocyte ratio (NLR), and platelet-to-lymphocyte ratio (PLR) levels in patients with type 2 diabetes at different stages of diabetic retinopathy (DR).
METHODS: This retrospective study included 141 patients with type 2 diabetes mellitus (DM): 45 without diabetic retinopathy (NDR), 47 with non-proliferative diabetic retinopathy (NPDR), and 49 with proliferative diabetic retinopathy (PDR). Complete blood counts were obtained, and NLR, PLR, and SII were calculated. The study analysed the ability of inflammatory markers to predict DR using receiver operating characteristic (ROC) curves. The relationships between DR stages and SII, PLR, and NLP were assessed using multivariate logistic regression.
RESULTS: The average NLR, PLR, and SII were higher in the PDR group than in the NPDR group (P=0.011, 0.043, 0.009, respectively); higher in the NPDR group than in the NDR group (P<0.001 for all); and higher in the PDR group than in the NDR group (P<0.001 for all). In the ROC curve analysis, the NLR, PLR, and SII were significant predictors of DR (P<0.001 for all). The highest area under the curve (AUC) was for the PLR (0.929 for PLR, 0.925 for SII, and 0.821 for NLR). Multivariate regression analysis indicated that NLR, PLR, and SII were statistically significantly positive and independent predictors for the DR stages in patients with DM [odds ratio (OR)=1.122, 95% confidence interval (CI): 0.200–2.043, P<0.05; OR=0.038, 95%CI: 0.018–0.058, P<0.05; OR=0.007, 95%CI: 0.001–0.01, P<0.05, respectively).
CONCLUSION: The NLR, PLR, and SII may be used as predictors of DR.
Dynamics of atom-atom entanglement in two-atom model with degenerate two-photon raman transitions
Authors: Othman A. , Bashkirov E. K.
Published: April 2024

The exact dynamics of a model consisting of two two-level atoms interacting with the electromagnetic field mode of an ideal resonator through degenerate Raman transitions are found for coherent and thermal field states. The exact solution is used to calculate atom-atom negativity. It is shown that for separable initial states of atoms, their interaction with the resonator field does not lead to the occurrence of atom-atom entanglement. It was found that for the Bell initial states of atoms in the case of a coherent resonator field, the effect of sudden death of entanglement takes place for large average values of the number of photons in the resonator, while in case of thermal noise, this effect is absent for any intensities of the resonator field.

A set of modeling programs for constructing a sequence of energy zones of heterojunctions is presented for analyzing the distribution of charge carriers in the heterostructure and internal characteristics, for describing the processes of charge transfer and accumulation. Wolfram Mathematica analytical system and Delphi programming language were used. The main elements of materials are semiconductors, metals of contact structures and injection regions of nonequilibrium carriers. The programs allow determining the structural characteristics of materials, active zones and spatial charge regions, calculating quasi-Fermi levels and built-in potentials, as well as the efficiency of heterostructures in general and for separation-charge collection, charge accumulation, determining the type of metallization of barrier or ohmic contact.
Dynamics of entangled Greenberger — Horne — Zeilinger states in three qubits thermal Tavis — Cummings model
Authors: Bagrov A. R. , Bashkirov E. K.
Published: April 2024

In this paper, we investigated the dynamics of systems of two and three identical qubits interacting resonantly with a selected mode of a thermal field of a lossless resonator. We found solutions of the quantum time-dependent Liouville equation for various three- and two-qubit entangled states of qubits. Based on these solutions, we calculated the criterion of the qubit entanglement — fidelity. The results of numerical calculations of the fidelity showed that increasing the average number of photons in a mode leads to a decrease in the maximum degree of entanglement. It is shown that the two-qubit entangled state is more stable with respect to external noise than the three-qubit entangled Greenberger — Horne — Zeilinger states (GHZ). Moreover, a genuine entangled GHZ-state is more stable to noise than a GHZ-like entangled state.

Authors: Karpishkov A. V. , Saleev V. A. , Shilyaev K. K.
Published: April 2024

In our work we consider prompt J/ψ and ψ′ production within the approaches of nonrelativistic quantum chromodynamics and generalized parton model. We use various experimental data (√s = 200 GeV and √s =19.4 GeV) of charmonium production to fit octet nonperturbative matrix elements and averaged values of initial partons’ transverse momenta. Further, we make evaluation with the extracted parameters and predict J/ψ production cross section and polarization of J/ψ and ψ′ at NICA collider energy √s = 27 GeV.
Validation Evidence for the Oviedo Grit Scale (EGO) in a Non-Western Context
Authors: Turnalar-çetinkaya Neslihan
Published: April 2024

Grit is a positive non-cognitive characteristic related to perseverance and passion for long-term goals. It positively impacts various aspects of life, but limited tools are available for measuring it, particularly in Turkish. Thus, this research aimed to establish the psychometric values for the Turkish version of the Oviedo Grit (EGO) scale by Postigo et al. (2021). The sample consisted of 500 Turkish university students. The analyses for single items, structural validation, measurement invariance, and the scale’s relationship with personality traits (i.e., big five personality dimensions) and external variables (i.e., grade point average) supported the claim that the EGO scale, originally developed in Spanish by Postigo et al. (2021), is a reliable, unidimensional tool to measure grit Turkish language. Some limitations and potential paths for future research were also discussed.

Does tourist guides' perceptions of quality of work life effect their perceptions of responsible tourism?
Authors: Aylan Serkan , Bayraktar Sukran Nur
Published: April 2024

The rapid development of tourism movements in recent years has brought to the fore concerns about the economic, socio-cultural, and environmental carrying capacities of tourism destinations. Sustainable tourism policies, like responsible tourism, should be adopted by countries that see the significance of building tourism around pristine natural and cultural resources. This will help to pass on their values to future generations and ensure that they continue to generate economic benefits. It is important to determine the responsible tourism perceptions of tourist guides, who are important stakeholders in the tourism industry and are conscious of the protection of the natural environment in the tours they manage. In this context, it is aimed at determining whether tourist guides' perceptions of the quality of work life have an impact on their perceptions of responsible tourism. For this purpose, first a conceptual framework was developed, and then data from the study were collected from 405 tourist guides with face-to-face surveys that contained the Work-Related Quality of Life Scale (WRQoL) and the Scale of Responsible Tourism (SRT). The study’s data were analyzed with a statistical package program and discussed in terms of descriptive and inferential statistics. As a result of the analysis, it has been determined that there is a significant relationship between the perceptions of quality of work life and the perceptions of responsible tourism of tourist guides. In addition, with the regression analysis, it was seen that quality of work life perceptions positively affected the responsible tourism perceptions of tourist guides.
