Published: January 2024

The chemical composition (polyphenols) of the leaves of the Crataegus pontica K. Koch plant has been studied. The process of isolating polyphenols from plant raw materials includes several stages: extraction of raw materials, processing of the extract with organic solvents, evaporation, precipitation of the sum of polyphenols, purification. The increase in the efficiency of the use of raw materials is achieved mainly at the first stage – extraction. The yield of the sum of polyphenols was studied depending on: the composition of the extractant, the extraction modulus, the multiplicity of extraction, the ratio of raw materials – extractant, temperature, thickening conditions, treatment of the aqueous residue with organic solvents, the conditions of precipitation of the sum of polyphenols and their drying. As a result, optimal conditions for the isolation of polyphenols from plant raw materials were selected, and the found condition obtained the sum of polyphenols from the autumn leaves of pontic hawthorn with a yield of 4.5%. Chromatographic study of the isolated fractions revealed that the polyphenols of the ethyl acetate fraction are mainly represented by monomeric catechins, flavonolams and tannins. The sum of polyphenols from the ethyl acetate fraction was divided on a column with sephadex LH-20 using chloroform-methanol as an eluent in various ratios (10 : 1→3 : 1). The structures of the isolated compounds were determined using physicochemical methods. As a result, more than 12 polyphenols were isolated from the leaves of pontic hawthorn, such as quercetin-3-O-β-D-galactopyranoside (hyperoside), quercetin-3-rutinoside, 3,5,7,3',4'-pentaoxyflavone (quercetin), 2-(3,4-dimethoxyphenyl)-7methoxy-3,4-dihydro-2H-chromene-3,4,5,6-tetrol, aрigenin-6-C-glycoside, procyanidin B, (+)-catechin (5,7,3',4'-tetraoxyflavan-3-ol), (-)-epicatechin (5,7,3',4'-tetraoxyflavan-3-ol), ellagic acid, gallic acid, 1-O-galloyl-4-O-catechin-β-D-glucose and caffeic acid ester with 2,3-dihydroxyglutaric acid. Of these, the last two substances were first isolated from this plant.

The change in the quantitative composition of secondary metabolites in the forming plant tissue is associated with climatic conditions of plant growth, including seasonality and the growing season. Acclimatization of evergreen coniferous trees in boreal regions includes regulatory processes that protect the photosynthetic apparatus of needles in specific conditions. Using the example of coniferous tree – scots pine (Pinus sylvestris), new experimental data on changes in the content of secondary metabolites of phenolic nature – participants in the processes of plant tissue biosynthesis – is presented in this paper. The dynamics of the intensity of phenolic metabolism and the quantitative change of the pigment apparatus of pine needles during the growing season were investigated using a complex of physic-chemical methods (UV spectrophotometry, HPLC, redox-metry) and the composition of the phenolic fraction of the phenol-quinone redox system of the cell wall was studied. It is shown that changes in the quantitative and qualitative composition of the phenolic compounds fraction that determine the redox state of the plant matrix occurs in plant tissue throughout the growing season. It is noted that dynamic self-regulation processes involving a complex consisting of phenolic compounds, pigments and enzymatic systems are a common pattern at all stages of plant development, ensuring that they perform protective functions of the photosynthetic apparatus of the needles of evergreen coniferous trees in boreal regions.

Correlative evaluation of the corrosion resilience and passivation properties of zinc and aluminum alloys in neutral chloride and acid-chloride solutions
Authors: Loto Roland T.
Published: January 2024

Comparative analysis of the corrosion resilience and passivation characteristics of pure zinc (Zn) and aluminum (Al) alloys in neutral chloride and acid-chloride solutions at 0.5–3% NaCl concentrations was done with potentiodynamic polarization, potentiostatic evaluation, optical characterization, and open circuit potential measurement. Results show Al alloy was more resistant to general corrosion in both solutions with values ranging from 0.031 to 0.082 mm/year, and 0.037 to 0.389 mm/year compared to Zn alloys with values of 0.432–0.691 mm/year and 0.465–5.016 mm/year. Corrosion potential values of Zn alloy were significantly more electronegative than the values for Al alloy. The passivated region of the polarization plots for Al was thermodynamically unstable with visible current transients compared to that of Zn. Passivation of Al occurred at the early onset of anodic polarization in the neutral chloride solution. Zn alloy passivated at specific potentials, coupled with stable passivation behavior. The passivation range values of Al were generally greater than the values for Zn due to delayed stable pitting activity. Optical images for Al showed extensive localized degradation along specific regions and grain boundaries, whereas Zn morphology indicates general surface degradation. Open circuit potential plots indicate significant growth of Al2O3 oxide on Al coupled with active–passive transition behavior of the oxide. This contrasts the observation for Zn where the plot configuration indicates limited oxide formation and growth but significant thermodynamic stability.
Valenced Priming with Acquired Affective Concepts in Music
Authors: Lahdelma Imre , Eerola Tuomas
Published: January 2024

This study tested whether chords that do not differ in acoustic roughness but that have distinct affective connotations are strong enough to prime negative and positive associations measurable with an affective priming method. We tested whether musically dissonant chords low in valence (diminished, augmented) but that contain little acoustic roughness are strong enough in terms of negative affective connotations to elicit an automatic congruence effect in an affective priming setting, comparable to the major-positive/minor-negative distinction found in past studies. Three out of 4 hypotheses were supported by the empirical data obtained from four distinct sub-experiments (approximately N = 100 each) where the diminished and augmented chords created strong priming effects. Conversely, the minor chord and the suspended fourth failed to generate priming effects. The results demonstrate how automatic responses to consonant/dissonant chords can be driven by acquired, cultural concepts rather than exclusively by acoustic features. The obtained results of automatic responses are notably in line with previous data gathered from self-report studies in terms of the stimuli’s positive vs. negative valence. The results are discussed from the point of view of previous affective priming studies, cross-cultural research, as well as music historical observations.

The Hidden Value in the “Black Swan” Pandemic Synergistic Externalities Creates Opportunity Value Reversing Application of Black-Scholes Option Pricing Model (BSOPM)
Authors:   Graduate School of Education & Psychology, Pepperdine University, USA, Gui Hairong , Gillpatrick Tom ,   Portland State University, USA, Bloom William ,   Portland Community College, USA
Published: January 2024

The worldly pandemic crisis creates unprecedented external value effects. These effects result in unexpected economic externalities which generate unexpected synergy value in investment valuation. 2020 global pandemic is an extraordinary example of such synergistic externalities. We aim to conduct research in the reversing application of the Black-Scholes Option Pricing Model (BSOPM). In the past, BSOPM failed when extreme unexpected events occurred. The normality assumption of the Black-Scholes model does not capture extreme movements. However, the reversed application and empirical testing results demonstrate the greater volatility, the greater the return. It is axiomatic that risk and reward are positively correlated, even when “black swan” events occur. This is unconventional and contradicted with valuation intuition. Technology has greatly advanced. The information travels in nanoseconds hence breaking the “norm”. Is it possible the “Black Swan” creates values through the exceedingly high fluctuation? In this paper, we will evaluate the hidden value in the “Black Swan” — that is, examine the pandemic global impact (synergistic externalities) and how this disaster creates opportunity value. We target to research on the reversing application of Black-Scholes Option Pricing Model (BSOPM) in such an evaluation and recommend how to utilize the BSOPM model-thinking to strategize the organization’s agility to anticipate the “unexpected”.
Potential to Setting Up of Maritime Clusters in Angola
Authors:   Ministry of Economy and Planning, Angola, Henriques Leitão Gabriel , de Lourdes Bravo Maria ,   Economics Faculty, University Agostinho Neto, Luanda, Angola
Published: January 2024

This paper seeks to address the relationship between the concentration of economic activities associated with the sea and Angola’s economic development. The investigation on Maritime Clusters arises from the fact that Angola has maritime infrastructures and a strong maritime activity being the sea hinterland of landlocked countries in Southern and Southern Central Africa. It is also experiencing socio-economic and demographic changes generated by economic activities with a relevant impact on the business environment, bringing about opportunities for the establishment of industrial clusters in particular maritime clusters. Thus, this paper aims to understand that the setting up of clusters might reduce regional asymmetries and poverty in the country, showing the importance of maritime clusters for economic development and job creation by enhancing the growth of solid micro, small and medium-sized enterprise (MSME). It also enables to understand that maritime clusters are relevant not only to the diversification of country’s economy that is still largely dependent from the oil industry but also to the integration of the Angolan economy in the Southern African Development Countries (SADC). Regarding the existing gap in knowledge about the issue, this research work represents an analytical contribute for further research initiatives, particularly quantitative nature.
Phenolic compounds and antimicrobial activity of leaves of the genus Sorbus species and natural hybrids
Authors: Liashenko O. V.
Published: January 2024

The identification of new sources of biologically active substances is an actual direction of research in recent years, in particular, the demand for antimicrobial compounds and natural preservatives of plant origin is growing. Plants of the genus Sorbus L. are known in folk medicine, but for the rational use of plant material, there is a lack of systematic study of the features of the secondary metabolites’ accumulation and the spectrum of biological activity of plants during vegetation in different environmental conditions. In the present work, the seasonal dynamics of the total content of polyphenols, flavonoids and free phenolic acids in the leaves of rowan plants natural to the flora of Ukraine and introduced in the steppe region were investigated. The highest accumulation of phenolic compounds was found in the leaves of S. domestica, S. latifolia, S. hybrida, S. torminalis and S. aucuparia in the first half of June, and in S. aria and S. intermedia in May, which will serve as a criterion for selecting the best plant material to obtain biologically active compounds. The seasonal dynamics of the content of flavonoids and phenolic acids in the leaves of plants had significant species differences, which require more in-depth studies of the phytocompounds component composition. Antimicrobial activity of leaf ethanol extracts of rowan plant was found to be high against gram-negative bacterial strain Klebsiella pneumoniae B920 (especially the activity of S. aria, S. intermedia and S. aucuparia extracts) and Pseudomonas aeruginosa B907 (especially the activity S. torminalis and S. domestica), clinical gram-positive strains of Staphylococcus epidermidis (the highest activity of S. aria, S. domestica and S. intermedia extracts), as well as against clinical strains of fluconazole-resistant fungus Candida albicans (especially the activity of extracts of S. latifolia S. torminalis and S. intermedia). A conclusion was made about the prospects of using leaf extracts of the genus Sorbus plants as an economical and affordable natural source of biologically active polyphenols with a wide spectrum of antimicrobial activity. Further research may be aimed at elucidating the component composition of rowan leaf extracts and establishing the relationship between individual phytocompounds and the antimicrobial effects of plant extracts.

The fund collection of tropical and subtropical plants in protected soil, where the total number of taxa is 830 units from 105 families, and those listed in the Red Book of Ukraine and international lists are more than 70 (28 families), among them, the vast majority of species (60) are included in the World Red List and, in particular, Adiantum capillus-veneris L. – in the Red Book of Ukraine has been studied. The geographical origin and life forms of the collection species needed protection are studied. Their habitats have been found to represent almost all areas of the tropics and subtropics; there are a large number of endemics, including the Galapagos Islands, Madagascar, and the islands of Norfolk and Rodriguez. Among the life forms, most belong to succulents (35 taxa) and trees (20). The taxonomy and systematic position of species according to the classification of the Angiosperm Phylogeny Group (APG IV) have been determined. It has been determined that almost all rare and endangered plants of the Laboratory of the Tropics and Subtropics of DNU have a decorative appearance and can be used in the phytodesign of various interiors, some of them are plants in which fruits, leaves, stems and other parts have a high biological value, in particular as a source of antioxidants, and are a source of physiologically active compounds and vitamins, can be raw materials for the pharmaceutical and food industries. It was found that the largest number among the species in need of protection is the life form of succulents. Among them, the family Cactaceae Juss dominates: 13 genera, 16 species and the family Xanthorrhoeaceae Dumort. – 7 species of Aloe L. The collection of tropical and subtropical plants of the DNU Botanical Garden is constantly used for educational work among the population, thousands of people visit it throughout the year. Protected soil plants serve as the basis for environmental education for adults and children, schoolchildren in particular from the Junior Academy of Sciences, students.
Only Pottery Drums in the Stone Age?
Authors: Chroustovský Luboš
Published: January 2024

Hundreds of possible prehistoric pottery drums made in Central Europe, mainly from the Late Neolithic (especially the TRB culture) have been found. Their forms vary from funnel-shaped, goblet to hourglass. It is not difficult to imagine equivalent or alternative forms of drums made from hard plant tissues, which are missing in the archaeological record during these or even other periods. Aside from a thought experiment based on archaeological knowledge, experimental and experiential research is presented here with three main examples of wooden drums – a simple frame drum from a branch imaginable since the Palaeolithic, a cylindrical double-headed drum made from a log with a rotten inside, and a wooden alternative to a TRB goblet drum that is compared to a ceramic replica of the same type of TRB drum in terms of material characteristics, technology, tools, skill, productions costs, time requirements and durability. The experience and results prove that simple frame drums are the fastest and the easiest option, followed by cylindrical drums made from logs, however production costs of wooden vessel drums greatly exceed those of pottery ones. Thin walls make ceramic drums much worse in terms of manipulation, playing and durability, but fairly better in clear and loud sound production. The presented examples are closely related to Central European prehistory, but they may serve as valuable analogies to other geographical or cultural contexts as well.
Infrastructure resilience under a changing climate: the urgent need for engineers to act
Authors: Dora John , Ferranti Emma Jayne Sakamoto
Published: January 2024

Extreme weather events are increasing in frequency and intensity, as are associated hazards such as floods, wildfires and overheating. Long-term sea level rise could have devastating impacts on coastal communities. In the last 20 years there has been steady progress in embedding climate adaptation within engineering practice, but the climate is changing more rapidly than the engineering sector is responding. This short piece outlines the challenges and progress in adapting to climate change, and the tools available for engineers to act, now, to enable infrastructure resilience within our rapidly changing climate. Engineers can use sector guidance and international (ISO) and British standards to plan, design, refurbish, maintain and operate infrastructure under a changing climate. There are tools to build organisational capacity, so that key decision makers are aware of the need to address climate change and have the leadership to access expertise and implement change. The ICE and fellow engineering institutions must promote climate awareness and capacity building both for students in higher education and at a strategic level within their membership.
Los flujos globales de ‘Para leer al Pato Donald’ y la censura de Disney

Published: January 2024

A 51 años de la publicación del libro “Para leer al Pato Donald” se analizan las razones por las cuales después de ser censurado en Chile en 1973 y prohibido en Estados Unidos en 1975, pudo difundirse en más de 20 ediciones y 15 idiomas. Bajo una revisión documental de las ediciones, en especial las versiones español, inglés y francés que le dieron un tinte académico comunicacional y un contexto de colonialismo de masa. Se encontró que fueron editoriales independientes las que lograron difundir el libro como un producto de contracultura vigente y una preocupación de traductores y prologuistas locales sobre cómo Disney penetró en sus países con una extraña y peligrosa fascinación de las clases medias.

El discurso de odio tiene el potencial de fomentar prejuicios y estereotipos negativos hacia aquellos grupos sociales que son objeto de estos ataques, socavando los principios rectores de la democracia, como la inclusión, la igualdad y los derechos humanos. Este fenómeno social puede propagarse de manera insidiosa a través de discursos políticos, medios de comunicación y plataformas digitales. Para afrontar este problema, se ha propuesto la implementación de estrategias educomunicativas destinadas a mitigar sus efectos perjudiciales. El diseño metodológico de este enfoque implica el análisis de contenido de las noticias publicadas por agencias internacionales desde el 1 de enero hasta el 31 de diciembre de 2022, relacionadas con el discurso de líderes políticos de extracción derechista, como Jair Bolsonaro (Brasil), y de extracción izquierdista, como Nicolás Maduro (Venezuela). Los resultados ponen de manifiesto que los políticos populistas examinados recurren de manera consistente a la técnica retórica de demonización en sus discursos. Como resultado, se han identificado una serie de estrategias educomunicativas destinadas a fomentar el desarrollo de una conciencia crítica en la ciudadanía a través de la creación de nuevos escenarios políticos.

A Collection of the Early Medieval Materials from Częstochowa-Mirów
Authors: Młodkowska-Przepiórowska Iwona
Published: January 2024

In 1962, pottery ceramic materials from the early medieval period were found in the graves of the Lusatian culture. They came from a hearth pit and probably from off-site layers. There is the Gąszczyk settlement about 520 m away in a straight line, north-west from the Site 1. Among the surviving and documented medieval museum pieces, particular attention should be paid to the reconstructed pot, fragment of a vessel with cylinder-shaped neck and the fragment of a bottom with a pottery mark. On the basis of individual diagnostic traits, the set of the discovered pot ceramics can be dated widely, from the 7th / 9th until the 13th century. Such early dating can be misleading, however, because it is based only on the ornamentation of the pottery vessel and the technique of manufacturing the vessels – hand-crafted moulding and poorly shaped rolling. The pot appears to have been made by an inexperienced potter, and it can be treated, it seems, as an inept specimen. Perhaps, this is why a hole was made in its bottom and it was used for other purpose than kitchen work. The other materials appear to be chronologically younger and should be generally dated to the period between the 11th and the 13th century, as well as to the late medieval period. The cave discovered by W. Błaszczyk, PhD, is probably a tiny fragment of the indeterminate early medieval settlement used also in the late medieval period.
Ângela Diniz e Mariana Ferrer: um olhar da psicanálise sobre o feminino
Authors: Portela Jéssica Bertoldo , Guazina Félix Miguel Nascimento
Published: January 2024

O presente trabalho caracteriza-se como uma pesquisa de cunho qualitativo e exploratório, fundamentado através da teoria psicanalítica. Propôs-se a analisar o discurso sobre o corpo da mulher em situações de violência no Brasil, bem como refletir sobre as produções psicanalíticas acerca do feminino na atualidade. Em primeiro momento, realizou-se uma apresentação da historicidade do corpo feminino, nas dimensões do público e do privado, além de uma análise crítica da influência da Psicanálise na construção teórica e social acerca da mulher. Em sequência, foram realizadas análises de notícias do caso Mariana Ferrer e do podcast “Praia dos Ossos” (2020) referente ao caso de Ângela Diniz. A partir do que foi apresentado neste trabalho, entende-se que é de extrema importância compreender que as violências, a revitimização e a culpabilização das mulheres são consequências que os corpos femininos sofrem por ocuparem o espaço público da vida social, assim como a relação dos discursos sociais com os dispositivos midiáticos que - em casos como esses - são capazes de alterar as narrativas sobre as possíveis “justificativas” para os crimes cometidos e proporcionar uma troca de papéis entre os culpados e inocentes.

Os participantes responderam a um protocolo contendo dados sociodemográficos, a EAER-HIV-7, a Escala de Preconceito Contra Diversidade Sexual e de Gênero (EPCDSG), um questionário de conhecimentos sobre a transmissão do HIV e questões sobre percepção de risco de infecção por HIV. Foi realizada tradução e adaptação transcultural da EAER-HIV-7. Para analisar os dados, foram utilizados testes t para avaliar a validade convergente e entre grupos, bem como análise fatorial confirmatória (CFA) para investigar a estrutura fatorial. O modelo unidimensional da EAER-HIV-7 testado apresentou bons índices de ajuste. Os resultados indicam boas evidências de fidedignidade da EAER-HIV-7, sugerindo sua aplicabilidade no contexto brasileiro. Sugere-se que mais estudos sejam conduzidos em populações diversas, como mulheres, idosos, pessoas LGBTQIA+ e indivíduos casados, de modo a oferecer novas versões da ferramenta.

Published: January 2024

Os Centro de Atenção Psicossocial Infanto-Juvenis se constituem como um dispositivo de cuidado dentro da Rede de Atenção Psicossocial. O serviço atende crianças e adolescentes com demandas de cuidados em saúde mental e se integra ao Sistema Único de Saúde. Nessa perspectiva, o trabalho tem como objetivo compreender o processo de alta no campo da saúde mental em um Centro de Atenção Psicossocial Infanto-Juvenil a partir de relatos dos profissionais da equipe que o compõe. Trata-se de uma pesquisa qualitativa de caráter exploratório e utiliza entrevista semiestruturada para a compreensão do papel dos vinte profissionais de saúde mental na construção do processo de alta relacionado ao tempo prolongado de tratamento. Como resultados, foi possível perceber o papel central que a instituição assume na vida de crianças e adolescentes, responsabilizando profissionais nela inseridos quanto a construção da alta e de um processo de autonomia. Além disso, visualiza-se o papel fundamental e pouco explorado da rede e da família, além da a escassez de investigações sobre o tema no cuidado em saúde mental para crianças e adolescentes em sofrimento psíquico.
Chimaliapan: resiliencia de una naturocultura lacustre
Authors: Montes-Ortiz Lucia , Blásquez-Martínez Lidia
Published: January 2024

Las ciénegas del Alto Lerma son los humedales remanentes de un gran cuerpo de agua que llegó a ocupar hasta 27.000 hectáreas antes de 1940 en el Estado de México, en México. Se trata de ecosistemas con características únicas que poseen una biodiversidad particular, y que, además fueron el cimiento del desarrollo del modo de vida lacustre, una relación interdependiente entre el ecosistema y los asentamientos aledaños a la zona. Actualmente, estos ecosistemas han sido reducidos a menos del 10% de su extensión original, poniéndolos en extrema vulnerabilidad. La extracción de agua en favor de la capital del país desecó grandes extensiones que ocupaban las ciénegas, a mediados del siglo XX, una visión de políticas públicas desarrollista planificó la expansión urbana y un corredor industrial. Sin embargo, aunque la naturocultura Ciénegas del Lerma es un relicto de lo que era, las especies endémicas aún sobreviven en la laguna y persisten las prácticas culturales como la pesca, el tejido de fibras vegetales, la confección de herramientas y gastronomía. En este artículo se propone un acercamiento a la comprensión de la laguna como un complejo de interconexiones que se transforman, debido a situaciones nuevas. Buscamos resaltar que la supervivencia de las ciénegas, a pesar de procesos tan violentos como la industrialización y el desecamiento, se debe a la reproducción del modo lacustre y a una ética del cuidado multiespecie. Si bien existe también una relación entre la pérdida de la biodiversidad y la cultura lacustre de la región, daremos ejemplos de resiliencia y resignificación de la naturocultura Ciénegas del Lerma, desde el enfoque de la bioculturalidad y el conocimiento situado.
Los esquemas discursivos prohibicionistas y la re-producción de marcos de discriminación e injusticia en el colectivo juvenil CTM
Authors: Cárdenas-Ramírez Wilmar Jeovany , Castellanos-Obregón Juan Manuel
Published: January 2024

En la investigación se analiza cómo el colectivo Cultiva Tú Mente (CTM) surgió como resultado de la defensa de la libertad de decisión sobre el uso recreativo de cannabis en espacios públicos. Su acción colectiva visibilizó las experiencias de injusticia que sufren sus usuarios como resultado de las políticas prohibicionistas nacionales e internacionales de drogas. Estas políticas generan efectos negativos en la vida cotidiana de las y los usuarios, quienes enfrentan formas de discriminación y violencia. Se realizó mediante un extenso ejercicio etnográfico articulado conceptualmente por los procesos enmarcadores (Goffman, 2006), las prácticas discursivas (Foucault, 1988) y la injusticia (Gamson, 1992). Durante su realización se identificó la existencia de tensiones políticas entre un modelo prohibicionista y un modelo liberal en la configuración e implementación de las llamadas políticas de drogas en el país. Los resultados indican que las dimensiones política y jurídica a nivel nacional e internacional contribuyen a la generación de maltrato, estigmatización y discriminación hacia los usuarios recreativos de cannabis, lo cual se convierte en la base de la configuración del discurso contrahegemónico de CTM.
Patient satisfaction with complete dentures received from an urban district hospital
Authors: Naidu Karmisha , Owen CP
Published: January 2024

To assess some of the factors that may contribute to patient satisfaction with a complete denture service provided by a district hospital in South Africa. The participants were patients who had received mucosa borne complete dentures at least one year previously. A questionnaire recorded demographics and treatment details either in person or telephonically. All patients were also asked to score a variety of factors related to satisfaction on a validated visual analogue scale. Associations were sought between patient demographics, treatment procedures and satisfaction. Sample size analysis required a sample size of 180 to detect at least a medium effect size, and 76 to detect large effect sizes. However, it was not possible to increase the sample size beyond 157 in the time available. Several associations were observed that were statistically significant, but most were of small effect. Even though 75% were upset at having lost their teeth, 64% reported that they had not minded wearing dentures. Overall, there were high levels of satisfaction, irrespective of the treatment procedures used. There were few meaningful associations between patient characteristics and satisfaction scores. It was clear that the patients had adapted well to their dentures. Patient satisfaction and patient adaptability are subject to many factors, and how patients cope, and what factors help remains unknown. It is clear the provision of this complete denture service in the public sector improved these patients’ quality of life and that patients can adapt to mucosa-borne dentures provided in a public setting.

The mediator role of ethical climate perception on the relationship between cyberbullying victimization and turnover intention: A research on remote workers
Authors: Disbudak Merve
Published: January 2024

Purpose- The more inclusion of information communication technologies in business life has also brought a new type of bullying which is cyberbullying. Traditional bullying has evolved into cyberbullying behavior in working life as a result of the increase in communication through information technologies with the increase in the remote working system and virtual work environments. In previous studies, the effect of cyberbullying on turnover intention was examined. Nonetheless, the mediating role of ethical climate in the relationship between these two has not been examined. This research is aimed to examine the association between cyberbullying victimization and turnover intention and to determine whether ethical climate perception performs as a moderator in that relationship.
Methodology- A qualitative study was carried out and purposive sampling method and snowball technique were used to obtain a sample of 204 white-collar workers who are working remotely at least 1 day a week outside of the office and working mainly in İstanbul and Kocaeli in Turkey. The analysis of data were done by using SPSS program.
Findings- The results showed that there is a positive relationship between cyberbullying and turnover intention, and ethical climate perception has a mediating role in this relationship.
Conclusion- This paper showed how critical the concept of cyberbullying is for organizations in business life by showing the relationship between intention to leave and cyberbullying victimization and the mediating role that the perception of ethical climate may have in this relationship. Moreover, this study has made practical contributions about how important ethical codes in companies are to ensure that employees do not leave their jobs by trusting the organization when they are exposed to negative behavior such as cyberbullying.
