The raw diatomaceous earth from the vicinity of Bitola (North Macedonia)
showed low bulk density (0.61-0.69 g/cm3), high-water absorption (75-81%)
and porosity (66- 72%). The chemical composition was determined with ICP-MS,
revealing the following results for the diatomaceous earth: SiO2 (63.69
wt%), Al2O3 (11.79 wt%), Fe2O3 (5.95 wt%), MnO (0.15 wt%), TiO2 (0.65 wt%),
CaO (1.51 wt%), MgO (2.24 wt%), P2O5 (0.13 wt%), K2O (1.64 wt%), Na2O (0.93
wt%), LOI (11.21 wt%). XRPD data of the examined sample of clayey diatomite
mainly depicted crystalline behavior with a small presence of amorphous
phase. The crystalline mineral phases mainly comprise: silica (quartz),
feldspars (plagioclase), mica (muscovite), chlorites and dolomite. SEM and
TEM results show cased presence of micro- and nanostructures with pores
ranging from 250 to 600 nm. The clayey diatomite was sintered at three
temperatures (900, 1000 and 1100?C) for a period of 1 h. XRPD of the
sintered samples at 1100?C showed certain thermal stability and formation of
new phases (mullite and tridymite) that makes the analyzed diatomaceous
earth suitable for production of various types of ceramic, construction and
thermal insulating materials.

Diabetes is associated with decreased epoxyeicosatrienoic acid (EET) bioavailability and increased levels of glomerular vascular endothelial growth factor A (VEGF-A) expression. We examined whether a soluble epoxide hydrolase inhibitor protects against pathologic changes in diabetic kidney disease and whether the inhibition of the VEGF-A signaling pathway attenuates diabetes-induced glomerular injury. We also aimed to delineate the cross talk between cytochrome P450 2C (CYP2C)–derived EETs and VEGF-A. Streptozotocin-induced type 1 diabetic (T1D) rats were treated with 25 mg/L of 12-(3-adamantan-1-yl-ureido)-dodecanoic acid (AUDA) in drinking water for 6 weeks. In parallel experiments, T1D rats were treated with either SU5416 or humanized monoclonal anti–VEGF-A neutralizing antibody for 8 weeks. Following treatment, the rats were euthanized, and kidney cortices were isolated for further analysis. Treatment with AUDA attenuated the diabetes-induced decline in kidney function. Furthermore, treatment with AUDA decreased diabetes-associated oxidative stress and NADPH oxidase activity. Interestingly, the downregulation of CYP2C11-derived EET formation is found to be correlated with the activation of the VEGF-A signaling pathway. In fact, inhibiting VEGF-A using anti-VEGF or SU5416 markedly attenuated diabetes-induced glomerular injury through the inhibition of Nox4-induced reactive oxygen species production. These findings were replicated in vitro in rat and human podocytes cultured in a diabetic milieu. Taken together, our results indicate that hyperglycemia-induced glomerular injury is mediated by the downregulation of CYP2C11-derived EET formation, followed by the activation of VEGF-A signaling and upregulation of Nox4. To our knowledge, this is the first study to highlight VEGF-A as a mechanistic link between CYP2C11-derived EET production and Nox4.

Article Highlights

Diabetes is associated with an alteration in cytochrome P450 2C11 (CYP2C11)–derived epoxyeicosatrienoic acid (EET) bioavailability. Decreased CYP2C11-derived EET bioavailability mediates hyperglycemia-induced glomerular injury. Decreased CYP2C11-derived EET bioavailability is associated with increased reactive oxygen species production, NADPH oxidase activity, and Nox4 expression in type 1 diabetes. Decreased CYP2C11-derived EET formation mediates hyperglycemia-induced glomerular injury through the activation of the vascular endothelial growth factor A (VEGF-A) signaling pathway. Inhibiting VEGF signaling using anti-VEGF or SU5416 attenuates type 1 diabetes–induced glomerular injury by decreasing NADPH oxidase activity and NOX4 expression.

Hvordan forstå progresjon i barnehagens rammeplan
Authors: Meland Aud Torill
Published: January 2023

En viktig endring mellom tidligere rammeplaner for barnehagen og rammeplanen av 2017 er at sistnevnte har en eksplisitt progresjonsorientering. Barnehageansatte skal sørge for progresjon og utvikling i barnehagens innhold. De skal planlegge for progresjon både for enkeltbarn og barnegruppen. Selv om progresjon har vært understreket av tidligere rammeplaner, er området lite undersøkt. Det er begrenset forskning på progresjon i barnehagesammenheng, men artikkelen løfter likevel frem perspektiv som kan være med å forklare begrepet teoretisk. Å legge til rette for progresjon krever imidlertid en forståelse av hvordan progresjon kommer til uttrykk i rammeplanen. Hensikten med denne artikkelen er å utforske hvordan progresjon fremstår i rammeplanen avgrenset til fagområdets målformuleringer. Dokumentanalyse anvendes som metode. Studien viser at på samme måte som skolens læreplan, uttrykker rammeplanen progresjon gjennom verb, kompleksitet og kvalitet. Verb uttrykker progresjon i utvikling av mestring og ferdigheter. For eksempel formidles en progresjon med kroppen som utgangspunkt med verb som å oppleve fysiske aktiviteter, videreutvikle motoriske ferdigheter, vurdere og mestre risikofylt lek gjennom kroppslige utfordringer.
English abstract
An important difference between previous framework plans for kindergarten and the framework plan of 2017 is that the last one has an explicit progression orientation. Kindergarten staff shall ensure progression and development in kindergarten content for each child and for the group of children as a whole. In kindergartens all children shall develop, learn, and experience progress. Although progression has been emphasized by previous framework plans, the area has been little investigated. Research on progression in kindergartens is hardly present. Nevertheless, the article highlights perspectives that may help explain the concept theoretically. However, facilitating progression requires an understanding of how progression is expressed in the Framework Plan for Kindergartens. The intention of this article is to explore how progression appears in the Framework Plan limited to the learning area’s goal formulations. Document analysis approach was followed. The study shows that in the same way as the school curriculum, the Framework Plan expresses progression through verbs, complexity and quality. In addition, the verbs express progression in the development of children’s mastery and skills. For example, verbs as experience physical activities, develop motor skills, evaluate and master risky play through physical challenges convey a progression in the use of the body.

O fenômeno da inclusão nas escolas da educação básica: um estudo sobre a exclusão
Authors: VIEIRA JULIANNA DA SILVA , MANRIQUE ANA LÚCIA
Published: January 2023

O direito à educação, apoiado por normas nacionais e internacionais, é um direito humano básico. Sendo assim, é importante que haja uma reflexão sobre a forma como esse direito é garantido. O presente estudo, refere-se aos desafios da educação inclusiva. Foi realizada uma revisão sistemática da literatura, que nos permite analisar os diferentes conceitos de exclusão, como certos movimentos ocasionam a exclusão escolar e quais as consequências da falha na efetivação de uma educação inclusiva. As consequências são alunos sentindo-se inferiores perante os demais, e tendo o retraimento e o desencadeamento de conflitos como respostas, provocando uma autoexclusão. Os autores citam ações que se propõem inclusivas, mas que geram exclusões, e concluem que as escolas ainda não aprenderam a lidar com as diferenças, que há falta de formação para os professores e que a educação ainda carrega heranças do processo de colonização.

Published: January 2023

O presente estudo tem por objetivo apresentar e discutir dados sobre a Formação Inicial de Professores de Matemática no Brasil, no período de 2010 a 2019, a partir de resultados do Instituto Nacional de Estudos e Pesquisas Educacionais Anísio Teixeira, a fim de compreender onde e como essa formação tem ocorrido e o que pensam os concluintes desses cursos a respeito do exercício do magistério. Os dados foram, por nós, sistematizados, interpretados e expostos utilizando-se da Estatística Descritiva. Refletimos sobre algumas questões levantadas a partir das contribuições de Gatti e Saviani. Os resultados mostram uma redução de matrículas nos cursos presenciais e a ampliação na modalidade a distância; que a média de concluintes é muito baixa comparada à média de matrículas e que cerca de 64% dos alunos prestes a concluir o curso pretendem atuar no magistério como carreira principal.
olhar sobre a regulamentação cambial brasileira no âmbito do direito internacional comercial
Authors: De Oliveira Hoerbe Gustavo Pedro
Published: January 2023

Este artigo se presta a analisar a temática da regulamentação cambial brasileira com um olhar sob o viés do direito internacional comercial. A análise do tema adquiriu relevância diante do arcabouço legislativo centenário que não mais podia prescindir de atualização. A promulgação da Lei 14.286/2021 – também chamada de novo estatuto do câmbio – constitui o mais recente passo da política cambial nacional com vistas a um melhor alinhamento ao cenário internacional. Vinda em boa hora – em tempos de relações virtuais, online e (quase) instantâneas, que parecem cada vez mais aceleradas – espera-se que possa contribuir para o desenvolvimento das relações comerciais no cenário internacional, oportunizando melhor alcance do país ao processo de globalização na atual sociedade de dados e da informação. A complexidade e multiplicidade de inter-relações possíveis, especialmente ao tratar-se de direito e economia, câmbio e comércio internacional, justifica o presente estudo, no sentido de identificar algumas das novidades trazidas pela nova legislação que, espera-se, facilitarão o processo de (re)inserção do país no ágil cenário comercial transfronteiriço. Nesse sentido, o presente artigo revisita alguns conceitos importantes sobre moeda e câmbio; percorre, ainda que panoramicamente, alguns marcos da secular história do câmbio, de maneira a demonstrar como foram forjados os principais conceitos jurídicos referentes a essa ferramenta nascida no seio do comércio internacional; e aborda, ao longo do texto, onde se integra o câmbio, quais os seus pontos de toque e de convergência com o direito internacional comercial.
Políticas públicas para a promoção da equidade de gênero
Authors: Porto Barros Gisele
Published: January 2023

O objetivo deste artigo é narrar, de forma breve e simplificada, embora significativa, a substancial contribuição das mulheres nas conquistas históricas e a incessante luta delas pela consecução de direitos. Por sinal, buscou-se demonstrar que a efetivação de direitos, em especial os sociais, depende de políticas públicas eficazes. E estas são necessárias também para o rompimento com estigmas pré-estabelecidos socio-culturalmente ao longo da História. Pretendeu-se demonstrar, a partir de uma análise evolutiva dos estereótipos conferidos às mulheres, como a construção de papeis sociais e os valores colocados durante a trajetória existencial dos seres humanos contribuíram para a inequidade de gênero tal como se verifica nos duas atuais. Como metodologia desta pesquisa qualitativa, adotou-se tanto a bibliográfica, como a consulta normativa. A título de resultados, apontou-se a necessidade da adoção de uma visão do mundo sob a ótica feminina e a implementação de políticas públicas de equidade de gênero como caminho para quebra desses estigmas e facilitação para o atingimento da igualdade substancial entre homens e mulheres. Considerou-se essas providências como possíveis para se romper com os ideais patriarcais e os processos de dominação e, enfim, se alcançar um mundo verdadeiramente humano, no qual as mulheres possam exercer a cidadania plena.

urgência da ortopráxis
Authors: Dias Tiago Cosmo da Silva , Souza Ney de
Published: January 2023

O artigo objetiva trazer à discussão a urgência de se resgatar a fé cristã mais como um modo de vida [ortopráxis] do que, propriamente, um conjunto de verdades de fé que precisa ser preservado [ortodoxia]. Parte-se do pressuposto de que a falta de humanidade, que hoje se assiste em tantas instâncias, inclusive na própria Igreja, brota de uma vivência da religião apenas como submissão a Deus, que impõe, para o ser humano, um conjunto de regras e costumes que precisam ser cumpridos como condição sine qua non para “ser feliz e chegar ao céu”. Esta relação, por sua vez, faz com que a “vida religiosa” aconteça quase que em separado da realidade, aumentando o tão agudo dilema entre fé e vida e comprometendo diretamente a fé cristológica do Deus que se fez homem para a todas e todos salvar. Como um exemplo concreto deste tipo de vivência, menciona-se o movimento Devolvam-nos a missa!, que emanou no auge da pandemia da Covid-19.
Oração e transcendência
Authors: Aquino Thiago Antonio Avellar de , Andrade Patrício Ana Clara de Andrade Patrício
Published: January 2023

O presente artigo abordou o tema da oração na visão antropológica da Logoterapia e Análise Existencial de Viktor Emil Frankl. Seu objetivo foi compreender a visão deste autor acerca da relação entre a oração e a transcendência na vivência do homo religiosus. Para atingir o seu escopo, tratou-se inicialmente sobre a visão de homem religioso para o autor em questão, quem é Deus para o homem religioso, a oração como liame entre o homem religioso e o supra-Ser e, por fim, abordou a compreensão de Viktor Frankl sobre oração e transcendência. Foi percebido que uma das manifestações comum a todas as religiões é a prática da oração, vivenciada tanto por místicos quanto pelo homem religioso comum. Conclui-se que o homem religioso ou espiritual, seria aquele que possuiria uma fé incondicional em um Suprassentido e a oração como uma via de transcendência que possibilita a religação com o supra-Ser, muitas vezes compreendido como um Deus pessoal.

Authors: Araújo Iriane Teresa , Formiga Nilton Soares
Published: January 2023

Com o aumento da competitividade tem provocado transformações na oferta de produtos e serviços, ao advento tecnológico, a inovação e ao comportamento do consumidor. Há uma crescente importância atribuída ao setor de serviços referente a seu desempenho dentro da economia, e é nesse meio, que o segmento de serviços digitais vem ganhando espaço na medida em que traz uma roupagem focada no cliente e suas respectivas necessidades. Este artigo pretende verificar o quanto a gestão do conhecimento digital influencia a agilidade organizacional perpassando pela adoção de estratégias digitais sejam elas em organizações públicas ou privadas. Participaram do estudo 295 trabalhadores, acima de 18 anos, homens e mulheres, de organizações públicas e privadas, respondendo o questionário com dados sociodemográficos, escala de gestão do conhecimento digital (GC), escala da estratégia digital (ED) e escala de agilidade organizacional (AgO), todas respondidas numa escala do tipo Likert de cinco pontos, Observou-se que a Gestão Conhecimento, associou-se positivamente, a Estratégia Digital, tendo esta, à Agilidade organizacional. No cálculo da análise de variância observou-se significativamente, que, quanto maior o escore no alto nível da GC, maior o nível de ED, em função do AgO. Comparando organização pública e privada, os três construtos revelaram maiores escores para organização privada. Com esses resultados, pode-se corroborar a hipótese estabelecida, bem como, propor uma perspectiva mais atual para os processos organizacionais referente a tomada de decisão e aos serviços digitais.

Awareness of medical college students about the formation of reproductive health
Authors: Kirillova AV
Published: January 2023

The study objective is to assess awareness of medical college students about formation of reproductive health. 80 female students from a medical college were surveyed concerning formation of their menstrual function; this survey was followed by an interview of 126 female students and 81 male students from medical colleges about their awareness of reproductive health protection and attitude to hygienic education regarding this topic. Data were processed using Statistica 13.0 (StatSoft, USA). 83.8% girls had their periods between 11 and 14, whereas in 7.5% of girls they started at the age of 15 and older. During the interview, 22.5% of girls had an irregular menstrual cycle. The conducted study revealed an insufficient awareness of students from a medical college of reproductive health formation. It produces a negative effect on their own health and will prevent subsequent effective hygienic education of different categories of population as far as this issue goes.
Simulacro, ironía y parataxis como características posmodernas en El arcángel ebrio de Jorge Fernández Granados y la felicidad es una pistola caliente de José Eugenio Sánchez
Authors:   , Hernández Luna José Alberto
Published: January 2023

Este trabajo ahonda en tres marcas de escritura presentes en El arcángel ebrio y la felicidad es una pistola caliente, de Jorge Fernández Granados y José Eugenio Sánchez, respectivamente. Una de ellas es la ironía, en tanto la voz lírica duda del acto mismo de enunciar. Por otro lado, observo una constante alusión a los modos como se genera ilusión por la vía del poema, lo cual se realiza en paralelo con el desenmascaramiento de ciertos productos de la cultura mercantil: la música, los espectáculos deportivos, el cine, la foto, etc. Tras la dificultad de asir el presente, de representarlo, surge una inclinación por lo inmediato y fugaz que, en su desbordamiento, aparece desjerarquizado y distante de las formas líricas convencionales (lo cual reviso desde la noción de parataxis). Todo ello es puesto a dialogar con una condición social, cultural y filosófica, que autores como Jean Baudrillard, Fredric Jameson, Octavio Paz y otros llaman “posmoderna”.
Aproximaciones a la nota roja: una propuesta de análisis
Authors:   , Vargas Maldonado Mauricio
Published: January 2023

En la presente tesis nos proponemos analizar cómo las notas rojas publicadas por el escritor José Revueltas para el periódico El Popular, entre 1938 y 1942, Espantoso Drama de Miseria, el libro de crónicas Aquí no es Miami (2012) de la escritora Fernanda Melchor y la crónica La pobreza que mata (2017) del periodista Óscar Balderas son ejemplos de lo que Michael Foucault denominara como “contra-notas rojas”. Si bien la configuración narrativa de la contra-nota roja asimila los rasgos narrativos y retóricos propios de la nota roja “sensacionalista”, los utiliza con la intención de provocar un giro semántico que ponga de manifiesto el relato de las desigualdades políticas, económicas y sociales que subyacen en las discursividades delincuenciales. Para ello, trazamos una genealogía de los relatos delicuenciales, así como los usos políticos del relato de nota roja. En un primer momento, esto nos permitirá identificar una serie de rasgos y ordenamiento narrativo, es decir, una configuración modélica (Barthes, Lara Klahr, Arriaga), para después observar cómo dichos elementos, de acuerdo con las formas y convenciones discursivas de cada época, se articulan para convertir la plana roja en un testimonio de denuncia social.
The Effect of Beneficial Autochthonous Microorganisms (Bams) on the Chemical Quality of Agricultural Soils and Olive Production in the Wilaya of Tlemcen (Western of Algeria)

Published: January 2023

Beneficial Autochthonous Microorganisms (BAMs) are a multi-purpose technology that has already been used in Latin America and Southeast Asia but is still unknown in Africa and particularly Algeria. The aim is to examine the effect of BAMs on agricultural soils and olive fields. The study was carried out in two degraded olive fields located in the Oued Tafna basin west of Tlemcen (The Semi-arid region in Western Algeria). The objective is to evaluate the effectiveness of BAMs on the chemical characteristics of the soils, particularly in terms of organic matter (MO), pH, electrical conductivity (EC), total limestone (CaCO3), moisture, organic carbon (C) and olive production and its weight. Statistical analysis (Independent Test) between all groups (treated and controls) showed a significant difference, in conductivity (EC) where we recorded “0.214±0.03μs /cm “ in treated soils vs. “0.198±0.029μs/cm “ in control soils a different statistical significance was recorded for the other parameters, however, it was observed that there is a relative increase in these parameters in the soils of the treated groups such as carbon (C): “2.85±1.06%” organic matter (MO): “4.91± 1.83%”, “pH=7.81±0.225”, “CaCO3 27.76±4.99% and a decrease in humidity “15.11±3.77%” compared to control soils. The results of statistical analyses (Mann-Whitney Test and Suite Test) of olive production showed a clear alternation (every other year) in fruit production in the control group and a positive effect of BAMs on olive production in the treated group, with a slight increase of production (19 kg in 2019 vs. 30 kg in 2020), but without any significant difference regarding the weight of the fruit between the two sessions. However, a highly significant difference “p=0.00<0.001” in fruit weight was noted between the treated groups “3.908g” and “5.70g” and the control ones “4.40g “ and “5.00g” in 2019 and 2020 respectively. The use of MAB is an interesting technique to restore the chemical properties of degraded soils, and increase olive tree production. To achieve more reproducible results (in terms of quantity and quality), sufficient doses of these BAMs and periodicals must be added to provide a good nutritional supplement and reduce farmers’ use of pesticides and mineral fertilizers.

We also give two examples that support our results.
On Chern classes of the tensor product of vector bundles
Authors: Szilágyi Zsolt
Published: January 2023

We present two formulas for Chern classes (polynomial) of the tensor product of two vector bundles. In the first formula the Chern polynomial of the product is expressed as determinant of a polynomial in a matrix variable involving the Chern classes of the first bundle with Chern classes of the second bundle as coefficients. In the second formula the total Chern class of the tensor product is expressed as resultant of two explicit polynomials. Finally, formulas for the total Chern class of the second symmetric and the second alternating products are deduced.
Employee scheduling and maintenance planning for safety systems at the remotely located oil and gas industrial facilities
Authors: Redutskiy Yury , Balycheva Marina , Dybdahl Hendrik
Published: January 2023

The safety of operations is vital in any process in the oil and gas sector, especially given that increasingly more hydrocarbon reserves are discovered in non-conventional remote and Arctic locations. Safety systems are designed as a part of a complex IT system for process control. The design of these systems is conducted in the form of an engineering project. This research presents a decision-making framework to facilitate formulating clear and comprehensive recommendations for the requirements specification developed for the safety systems. The contribution of this research to the strategic planning area of IT solutions for hazardous industrial facilities is integrating the problems of designing a safety system, planning its maintenance, and scheduling the employees to conduct the required maintenance. With this joint decision-making, it is possible to explore trade-offs between investments into the systems’ complexity and workforce-related expenditures throughout the solution’s lifecycle. The reliability modelling is conducted with the help of Markov analysis. The multi-objective decision-making framework is employed to deduce straightforward requirements to the safety system design, maintenance strategy, and workforce organisation. This research is relevant to managing the petroleum sector engineering projects with regard to the design of technological solutions.

Within the context of the COVID-19 pandemic, community-level medical institutions as health service centres have been gaining importance in the medical reform expansion. As prior research has not fully addressed how to index and evaluate the quality of medical service, this article proposes a framework based on the service quality gap theory and the three-faceted “structure–process–outcome” quality evaluation theory. The study took the medical services at Beijing’s Tianqiao Community Health Service Centre as an example to construct an index system for medical service quality evaluations. Data was collected from 211 people, and SPSS software was used for data processing and analysis. Due to the COVID-19 pandemic, patients without serious diseases tend to choose community hospitals to reduce their infection risk. As a result, they have growing requirements for clinics to have more departments and specialists. The studied community health service centre has encountered difficulties connected to low patient expectations, a poor medical environment, outdated hardware and equipment, and a low level of medical services. Some suggestions have been made to add specialised departments and consider the convenience of medical treatment for the elderly.

It is essential for manufacturers to consider the interrelation among quality, inventory, and maintenance decisions to detect imperfect quality products, keep the production system in good operating condition, and manage quality and inventory costs. Hence, this paper aims to develop an integrated model of inventory planning, quality engineering, and maintenance scheduling in which the expected total cost per time unit is minimised by determining the sample size, sampling interval, control limit coefficient, along with production cycle time. In this regard, an imperfect multi-product manufacturing system is considered, in which the inventory shortage in satisfying the demand for each product type and the idle time during the production cycle are not allowed. It is assumed that the process starts in an in-control condition where most produced units are conforming. However, due to the occurrence of an assignable cause (AC), the process mean moves to an out-of-control condition in which a significant fraction of non-conforming units is produced. The efficiency of the proposed mathematical model is evaluated by a numerical example, and then the sensitivity of the proposed model to important inputs is analysed. Finally, a comparative study based on the Taguchi design approach is given to confirm the capability of the proposed model to achieve remarkable cost savings.
Does Monetary Policy Solely Correct Disequilibrium in the Balance of Payment? Evidence From the Developing World
Authors: Khan Muhammad Azam
Published: January 2023

Monetary policy and balance of payments (BoP) are the key parameters in any country’s economy performance. This study is an attempt to re-explore the impact of domestic credit provided by the financial sector, real interest rate, real GDP growth, inflation rate, and exchange rate on the balance of payments by net foreign assets (NFA) in 17 developing countries over 1982–2019. The most appropriate empirical strategy has been implemented to obtain robust empirical results. The results indicate that domestic credit, interest rate, inflation and exchange rate have a significantly negative, while real GDP growth has a significantly positive impact on NFA. The results of Granger causality test reveals a bidirectional causality between domestic credit and NFA, between exchange rate and NFA. Furthermore, in the case of individual country analysis, overall empirical estimates of three estimators are acceptable for 17 individual countries although some dissimilarities are found between the countries in the magnitude of estimated coefficients of variables and level of significance. Empirical findings suggest that to correct the disequilibrium in BoP, central banks (monetary authorities) need to give equal consideration to other policy measures along with the monetary instruments to accomplish stability in a country’s BoP account.
Resilience and Path Dependency: Income Distribution Effects of GDP in Colombia

Published: January 2023

This study examines the effect of GDP per capita on the Gini index, which measures income concentration, in Colombia. The methodology used is an econometric analysis of time series with data extracted from the Inter-American Development Bank and the World Bank. The econometric results suggest that, at least during the period studied here, there is no evidence that GDP per capita has been an explanatory variable of the behaviour of income distribution in Colombia. The results also align with the understanding that the problem of inequality in the distribution of income is not merely economic but concerns persistent matters such as political and historical issues.

Pineapple is widely grown in tropical countries, and the fruits are well-known for their unique flavor. The ideal stage of maturity, optimum storage temperature, congenial relative humidity, and adequate type of packaging are critical factors that determine the shelf life and quality of pineapple fruits. Therefore, this investigation was carried out to determine the effect of maturity stage and shrink-wrap packaging, along with ambient and low-temperature storage in order to determine the impact of these factors on extending the shelf life and quality of pineapple fruits. The results revealed that fruits with 75% yellow tubercles at the harvesting stored under ambient temperature had a shelf life of just 7 days compared to the fruits having 25% yellow tubercles subjected to shrink-wrap packaging, followed by low-temperature storage, which had a shelf life of 49 days. The findings of this study conclusively proved that harvesting pineapple fruits with 25% of yellow tubercles, followed by shrink-wrap packaging in 25 μ polyolefin film and subsequent storage in a cool chamber at 12–13 °C and 85% relative humidity can prolong the shelf life and will also maintain the quality of pineapple fruits.
Digitalisation and Virtualisation of the Aesthetic Situation Management: Polish Musical Art Creators during the COVID-19 Pandemic
Authors: Szostak Michał
Published: January 2023

Objective: The characteristics of the creative process in musical arts depends on the form in which the aesthetic situation concerning musical arts takes place (traditional in-person or virtual with digital solutions) dangling on the nationality of the musical art creator: Polish versus non-Polish. The following research questions were asked: 1) How do the forced virtualisation and digitisation affect the quality of the creative process within the aesthetic situation between Polish and non-Polish musical art creators? 2) Which qualitative parameters of the aesthetic situation are lost and which are gained in connection with the creative process virtualisation in the eyes of Polish and non-Polish musical art creators?

Methodology: Qualitative, in the forms of literature review and interviews.

Findings: The study reveals differences in the traditional and virtual creative process between Polish and non-Polish musical art creators. The general differences are insignificant; however, particular components are concerned with essential discrepancies.

Value Added: A new approach to the creative process in musical arts depending on the traditional and virtualised forms of the aesthetic situation. This study can have practical implications for: 1) musical art creators to form their perception of the creative process; 2) musical art managers to form their perception of the complex nature of the creative process of musical art groups they manage; 3) musical art institution managers to form their perception of the multifaceted nature of the creative process of musical art creators involved in the institutions they manage; 4) sociologists looking for deeper understanding of the creative process in musical arts.

Recommendations: Perspectives of the research can be large-scale research based on the methodology invented for this paper and more focused research investigating art creators from different countries, regions, and cultures, divided by age, gender or the extent of artistic experience.
UE Organizational Identity. From the Motto Veritate Concordia to Neo-bureaucratic Management
Authors: Dziedzic Justyna
Published: January 2023

Objective: The concept of organizational identity appears mainly in the context of a symbolic-interpretive view of an organization’s functioning in its many dimensions. This article aims to analyze to what extent previous knowledge about the existence of an EU organizational identity is a distinct category in the context of neo-bureaucratic management. It seems particularly interesting to draw attention to the identity context in organizations operating under intercultural management conditions. Their character and disposition may be more complex than in the case of homogeneous organizations. For this reason, the European Union is asking itself questions about its identity in the context of cultural unification and policy issues, and management solutions related to the institution’s functioning at many levels. Therefore, it seems interesting to draw attention to these issues in light of the different contexts of influence. One is the neo-bureaucratic view of the EU institutions’ governance dimensions, which should be regarded as complex organizational identities. They are subject to the modern influence of management visions and benefit from intercultural management processes’ achievements. The EU’s supranational structure, influenced by bureaucratic organizational arrangements, speaking the language of diplomacy, and setting policy for the Member States, constitute a unique organizational identity globally, which is worth verifying through the prism of neo-bureaucratic influences and cultural conditions of European identity.

Methodology: The article is based on a critical analysis of literature dealing with the sense of European Union organizational identity. Provided a theoretical background on orgzniataional identity in neo-bureaucratic management on a European level.

Findings: In its institutional dimension, the European Union faces the dilemma regarding its own identity due to diplomatic disputes over cultivating indigenous cultures and diversity. It is, therefore, a rare phenomenon on the world stage of supranational institutions. Its procedural nature and purpose are also important to harmonize the Member States’ various policies. It is already possible to outline its unique organizational identity. However, it cannot be transferred to territorial and social land, as Europe cannot be a hybrid of cultures or unify its perspective in the face of historical pasts and ethnic representations.

Value Added: Critical discourse on the theory of bureaucratic management and organizational identity. Presentation of the role of European Union identity in management process and giving the organization common values that solidify its form.

Recommendations: Neo-bureaucratic management is an interesting phenomena to explore in cross-cultural discourses. There are several directions for analysis: forms of modern bureaucracy based on practices drawn from the experience of corporations; abuse of the power of supranational organisations; network management in international organizations.

Published: January 2023

Background

Pancreatic islet transplantation via infusion through the portal vein, has become an established clinical treatment for patients with type 1 diabetes. Because the engraftment efficiency is low, new approaches for pancreatic islets implantation are sought. The goal of this study is to explore the possibility that a non-thermal irreversible electroporation (NTIRE) decellularized matrix in the liver could be used as an engraftment site for pancreatic islets.

Materials and methods

Pancreatic islets or saline controls were injected at sites pre-treated with NTIRE in the livers of 7 rats, 16 hours after NTIRE treatment. Seven days after the NTIRE treatment, islet graft function was assessed by detecting insulin and glucagon in the liver with immunohistochemistry.

Results

Pancreatic islets implanted into a NTIRE-treated volume of liver became incorporated into the liver parenchyma and produced insulin and glucagon in 2 of the 7 rat livers. Potential reasons for the failure to observe pancreatic islets in the remaining 5/7 rats may include local inflammatory reaction, graft rejection, low numbers of starting islets, timing of implantation.

Conclusions

This study shows that pancreatic islets can become incorporated and function in an NTIRE-generated extracellular matrix niche, albeit the success rate is low. Advances in the field could be achieved by developing a better understanding of the mechanisms of failure and ways to combat these mechanisms.
