Authors: Alvarado-Peña Lisandro José , Amaya Sauceda Rosas Amadeo , Sansores Guerrero Edgar Alfonso , Rafael Sánchez Aurea Elizabeth
Published: May 2021

La investigación en cualquier ámbito es un pilar de desarrollo y crecimiento para una nación. Sin embargo, en los países que conforman América Latina nunca se le ha dado la verdadera importancia que tiene, tanto gobiernos como empresas es poca la inversión que destinan a laboratorios y centros de investigación; quedando rezagada para quienes por vocación propia decide llevar a cabo nuevas investigaciones. Aunado a esto, ahora se le suma el impacto económico que ha generado la presencia del virus Covid-19; y las transformaciones que se han tenido que realizar en las distintas actividades humanas, donde la educación superior y sus actividades de extensión no quedaron exentas de esta nueva normalidad, planteando nuevos retos implícitos en el cambio de plataforma presencial a virtual para seguir dando respuestas a la sociedad ante este contexto de pandemia. Por lo cual, el objetivo fundamental del presente estudio es describir la realidad y perspectivas de los Centros de Investigación Universitarios en América Latina ante el Covid-19, a través de una revisión sobre la bibliografía existente sobre el tema, fundamentándose en autores tales como: Paredes-Chacín; et al (2020), Urbaneja (2020), UNESCO (2020), el Instituto Internacional para la Educación Superior en América Latina y El Caribe (2020), entre otros; bajo una metodología interpretativa, transversal entre los años 2020 y 2021. Obteniendo entre los hallazgos más relevantes que a pesar de la poca importancia y baja asignación presupuestaria que a nivel gubernamental se le otorga a la investigación dentro del sector universitario, estas instituciones han sabido salir adelante, sobretodo en estos momentos de pandemia, incorporando los medios digitales a sus actividades y aprovechando las oportunidades aperturadas a nivel internacional para el mundo de la ciencia y seguir produciendo conocimiento direccionado a lograr el desarrollo socio-productivo de los países.
Cansancio emocional en médicos anestesiólogos, como factor asociado al síndrome de Burnout por el Covid-19
Authors: Galbán Padrón Neuro Fernando , Devonish Nava Nidia , Guerra Velásquez Mery , Marín Marcano Cesar José
Published: May 2021

Las exigencias laborales muchas veces generan en el individuo síntomas que van desde la irritabilidad a la depresión, acompañados por agotamiento físico y mental, representando éstos los primeros síntomas del síndrome de Burnout (SB) o estrés laboral crónico. Entre las circunstancias que deben enfrentar los anestesiólogos durante su desempeño, destacan sus largas y delicadas jornadas laborales, a la cual hoy se le suma la exigencia de las extremas medidas de bioseguridad que deben tener producto del Covid-19 y del temor al contagio durante sus operaciones, las cuales aumentan sus niveles de estrés e impotencia laboral. En este artículo bajo una metodología descriptiva, documental, se describirá el cansancio emocional en médicos anestesiólogos como factor asociado al estrés laboral crónico ó síndrome de Burnout por el Covid-19, en base a los fundamentos del origen del término Burnout introducido por Freudenberger en 1974 y las investigaciones de Maslach y Jackson desde el año 1982 hasta resultados de actuales investigaciones publicadas en revistas arbitradas de alto impacto sobre el tema estudiado, tales como las de Arayago Iriarte, et al., (2016), Rodríguez Paipilla, et al., (2011), Tobie-Gutierrez y Nava-López (2012), entre otros. Concluyendo que el cansancio emocional (CE), constituye un factor clave para la prevalencia del síndrome de Burnout (SB), manifestado a través de la pérdida progresiva de la energía, el desgaste físico, mental y cansancio; causado por la presencia continua de estos signos, sin ser diagnosticados ni tratados eficientemente.

Manejo Integrado do Fogo: Trajetória da Estação Ecológica Serra Geral do Tocantins (2001 a 2020)
Authors: Barradas Ana Carolina Sena , Torres Ribeiro Katia
Published: May 2021

O fogo tem sido considerado um fator-chave para a biodiversidade das savanas tropicais, em termos evolutivos e ecológicos, e por isso precisa ser melhor compreendido e melhor utilizado no manejo das áreas protegidas. Entretanto, por muitas décadas, prevaleceu a busca pela exclusão do fogo das áreas naturais mobilizando elevados investimentos em equipes e equipamentos. Repetidas vezes tal decisão de manejo resultou em grandes incêndios nas savanas, devido ao acúmulo e continuidade de material combustível, junto a elevados impactos sociais, especialmente para os povos e comunidades tradicionais. A constatação da inevitabilidade do fogo em tal contexto levou à aceitação de seu uso como um ‘mal necessário’ em algumas circunstâncias, quase que exclusivamente para controle de combustível e redução de incêndios. Uma terceira abordagem de gestão, emergente, entende o fogo como um fator ‘necessário’ tanto para a biodiversidade como para as pessoas que vivem em ecossistemas que evoluíram com o fogo, sendo que a definição de objetivos e estratégias de manejo deve ser alcançada em ambientes e processos multiatores. Vem sendo chamada de manejo integrado do fogo (MIF) esta abordagem que lida com diferentes expectativas e necessidades, respeitando especificidades locais. No Brasil, a mudança de paradigma da exclusão do fogo à adoção do MIF não deveria ser contada sem a experiência da Estação Ecológica Serra Geral de Tocantins, uma unidade de conservação (UC) de proteção integral criada em 2001 parcialmente sobre território quilombola. Uma década de manejo visando a exclusão do fogo nos mais de 700 mil ha de Cerrado protegidos pela UC levou a área ao topo do ranking de UC mais incendiadas no país, e as comunidades locais se viram ameaçadas em suas formas de vida, tanto pela recorrência de grandes incêndios como pela coibição de suas práticas tradicionais. A negociação de termos de compromisso com a comunidade quilombola envolveu estudos, oficinas, intercâmbios, capacitações e vivências que impulsionaram a transição entre paradigmas de gestão do fogo. Primeiro houve a aceitação do fogo como ferramenta, para confecção de aceiros, e desde 2014 o fogo é manejado sob múltiplas perspectivas, tanto pela equipe da UC como pelos quilombolas, considerando um horizonte comum e dialogado de criação de mosaico de regime de queimas. A premissa, sob investigação científica, é de que nos ambientes evoluídos com o fogo a pirodiversidade é correlacionada à biodiversidade. Grandes incêndios já não mais ocorrem, e percebe-se um ambiente muito mais saudável de diálogo, aprendizagem coletiva e de redução de conflitos. Essas mudanças de manejo foram incorporadas nos instrumentos oficiais de gestão, exigindo debates e aprendizagem em toda a hierarquia institucional. As experiências estão sendo compartilhadas com equipes de outras áreas protegidas em nível nacional e internacional.
The Top-Degree Part in the Matchings-Jack Conjecture
Authors: Burchardt Adam
Published: May 2021

In 1996 Goulden and Jackson introduced a family of coefficients $( c_{\pi, \sigma}^{\lambda} ) $ indexed by triples of partitions which arise in the power sum expansion of some Cauchy sum for Jack symmetric functions $(J^{(\alpha )}_\pi )$. The coefficients $ c_{\pi, \sigma}^{\lambda}  $ can be viewed as an interpolation between the structure constants of the class algebra and the double coset algebra. Goulden and Jackson suggested that the coefficients $ c_{\pi, \sigma}^{\lambda}  $ are polynomials in the variable $\beta := \alpha-1$ with non-negative integer coefficients and that there is a combinatorics of matching hidden behind them. This Matchings-Jack Conjecture remains open. Dołȩga and Féray showed the polynomiality of connection coefficients $c^\lambda_{\pi,\sigma}$ and gave an upper bound on the degrees. We show a dual approach to this problem and investigate Jack characters and their connection coefficients. We give a necessary and sufficient condition for the polynomial $ c_{\pi, \sigma}^{\lambda}$ to achieve this bound. We show that the leading coefficient of $ c_{\pi, \sigma}^{\lambda}$ is a positive integer and we present it in the context of Matchings-Jack Conjecture of Goulden and Jackson.
The Unsettlement of Tourism Studies: Positive Decolonization, Deep Listening, and Dethinking Today
Authors: Hollinshead Keith , Suleman Rukeya , Nair Bipithalal Balakrishnan
Published: May 2021

Recent years have witnessed the rise of many new and/or corrective approaches across the social sciences that have challenged the received assumptive frameworks through which the world is inspected and interpreted methodologically. Late decades have brought the rise of a new generation
of scholars who work through "resistance politics" approaches in pursuit of, for instance, social justice causes or posthumanist convictions. The purpose of this article (and its two companion articles in later issues of Tourism, Culture & Communication) is to capture the possibilities
and the tensions in the development and cultivation of such "disruptive" or "promiscuous" research acts, and to conceptually situate them within Tourism Studies—the domain that covers the "worldmaking"/"declarative power" of tourism to interpret and inscribe the peoples, places, pasts,
and presents across the globe. In principally mining the neoteric and landmark text Disruptive Qualitative Inquiry (Brown, Carducci, and Kuby), an attempt is made to locate the interruptive craft of such unfolding disruptive thinking of and about tourism as rising numbers of Tourism
Studies researchers themselves seek to decolonize their methodologies from the stranglehold of Western Modern Science and reverberate more positively with populations that have been subjugated or suppressed through tourism. In building up to the provision of a 30-term glossary (cumulatively
provided across the said three companion articles) delineating the fresh thinking that is involved in such disruptive inquiry, this first article targets approaches that beckon forms of interpretive plural knowability, which demand the fluid acumen to map the less-fixed/fast-changeable
populations of our time, and which are thereby decent yet rigorous in their critical multilogicality ; hence, this first article glossary covers terms such as "reversing the binaries," "promiscuous methodologies," and "working the hyphens." In this innovative light, the second companion
article glossary identifies conceptualizations such as "guided wandering," "postqualitative research," and "survivance" in order to expand the ontology and epistemology of Tourism Studies, while the glossary in the third article offers conceptualizations such as "uncrossable methodolodies,"
"helicopter research," and "stuckness," which—in their different ways—speak to the transformative rhetorics of futurity for tourism and the peoples and places of the world.

Objetivou-se por meio desse estudo desenhar o perfil social de consumidores de feiras livres em Maceió, Alagoas, Brasil, bem como compreender como estes percebem agricultura de base agroecológica e orgânica. Como procedimento metodológico foi adotado abordagem qualitativa e quantitativa, tendo como apoio a aplicação de questionários, os quais foram aplicados in loco de modo aleatório durante a realização das feiras. Os dados obtidos foram tabulados e expressos em porcentagem sob a amostra total e os dados qualitativos foram interpretados com base na literatura específica. Assim, as feiras livres observadas demonstram que seus consumidores apresentam todos os níveis de escolaridade e faixas etárias, sendo a maioria desses frequentadores do gênero feminino, entre 20-24 e 45-69 anos. A medida das faixas etárias examinadas corroboram que, quanto mais novo o consumidor maior o nível de escolaridade. Dos entrevistados, 89,44% expõem a importância da redução no uso de agrotóxicos ao associá-los com a produção de alimentos e os danos causados, como doenças respiratórias e de pele, representando 78,9% dos entrevistados. Esses dados mostram a importância da articulação da discussão sobre essas bases de se fazer agricultura e o reconhecimento de suas diferenças reafirmando o espaço de produção e reprodução da sociedade e o desenvolvimento de práticas mais sustentáveis.

Surto de mosca-branca em culturas do Paraná e São Paulo
Authors: Costa A. S. , Costa G. L. , Sauer H. F. G.
Published: May 2021

Bemisia tabaci ocorre em todo o Brasil em culturas e plantas da vegetação espontânea, geralmente em populações baixas. Em 1968, em algodoeiros, e em 1972/1973 em soja, algodoeiro e feijoeiro, foi registrado surto populacional elevado do inseto no Norte do Paraná e região de Ourinhos, SP. As viroses da soja (mosaico, encarquilhamento), do algodoeiro (mosaico comum) e do feijoeiro (mosaico anão e mosaico dourado) infetaram praticamente 100% dos feijoeiros dessas áreas. O surto anormal da mosca -branca registrado e atribuído a larga faixa de plantio de soja (novembro-janeiro) e as condições favoráveis de ambiente (verão longo e quente), que permitiram o desenvolvimento de grandes populações do inseto nos últimos plantios, passando então para o feijão da seca. A possibilidade de ser raça nova de alto potencial biótico foi considerada, mas não corresponde aos fatos. Se populações da mosca-branca continuarem elevadas em anos futuros e de se esperar aumento de importância econômica das viroses que transmite e provavelmente o aparecimento de novas molas- tias transmitidas por esse inseto nessas regiões. Controle químico da mosca-branca difícil e oneroso; considera-se que o estreita- mento da faixa de plantio da soja poderá reduzir a importncia do problema a proporções menores. É apontada a necessidade de uma intensificação das pesquisas sobre o controle da mosca-branca e nas áreas de resistência das culturas ao inseto e as viroses que transmite.

Authors: Corrêa B. S. , Smith J. G.
Published: May 2021

Um levantamento das espécies de Lepidoptera pragas da soja foi realizado em Ponta Grossa em 1973/74, verificando-se à ocorrência e flutuação das espécies durante o ciclo de desenvolvimento da soja, através do método de varredura e exame da planta.

E. aporema foi encontrada como sendo a segunda espécie de Lepidoptera mais abundante danificando a soja, ocorrendo densa população larval em fevereiro, final do período de flora1ão. Amostragens das larvas de E. aporema foram mais eficientes pelo método de exame de plantas enquanto o uso de rede foi melhor par a amostrar os adultos.

O dano foi causado pelo ataque das larvas aos brotos e folhas terminais ocasionando deficiente crescimento da planta e queda no rendimento, sendo as variedades tardias as mais prejudicadas.

Perception of L2 Spanish polite requests and impolite commands by Chinese migrant workers living in Spain
Authors: Herrero Cristina , Planelles Margarita , Alhmoud Zeina
Published: May 2021

Politeness plays a key role in cross-cultural communication and intercultural adaptation (Spencer-Oatey and Franklin 2009). Therefore, knowledge about (im)politeness and the acquisition of politeness strategies is central in the integration of immigrants and the achievement of social cohesion. At the same time, prosody is already known to directly affect politeness judgements in all studied languages, including L1 Spanish (Hidalgo 2009; Devís 2011; Albelda 2012). However, the prosodic cues on which L1 speakers rely when judging politeness seem to be different for each language. While L1 Spanish speakers seem to rely more on intonation when judging politeness (Devís 2011), L1 Chinese speakers tend to rely more on other prosodic cues when judging politeness in Chinese (Fan and Gu 2016). This study investigates whether Chinese immigrants in Spain perceive the difference between polite requests and impolite commands the same way L1 Spanish speakers do, when the only difference between the commands and requests is at the prosodic level. Chinese immigrants (N = 22) and L1 Spanish speakers (N = 26) listened to and judged the degree of politeness of 20 pairs of commands and requests produced by 4 L1 Spanish speakers (2 male + 2 female) from Madrid. Pairs of commands and requests had the same lexico-grammatical features and onlydiffered at the prosodic and pragmatic levels. Statistical analysis revealed that while commands were perceived very similarly by  chinese immigrants and L1 Spanish speakers, Chinese speakers had problems perceiving the intention in polite requests, which were rated as more polite by Spanish native speakers than by Chinese immigrants.

The Rhetorical Structure of Literature Reviews in Egyptian-Authored English Research Articles in Linguistics
Authors: Rabie Hend , Boraie Deena
Published: May 2021

The present paper seeks to examine the rhetorical structure of the literature review (LR) sections of English research articles (RAs) written by Egyptian researchers in the field of linguistics. For this purpose, a sample of ten LRs was selected from RAs published in local and international English-medium journals in linguistics between 2013 and 2019. The study deployed hybrid techniques and approaches for data collection (random/non-random sampling) and data analysis (genre-based/corpus-driven and qualitative/quantitative). Findings showed rhetorical variation in the LRs written by both groups, especially concerning Move 2 and Move 3 that were used more frequently in the international sample than in the local one, where the focus was on Move 1. In addition, some new steps emerged. The findings also shed light on the problems within the rhetorical structure of the LRs published locally, implying that the lack of rhetorical knowledge is one of the major reasons that hinder writing professional LRs. This paper contributes to a better understanding of the generic structure of RA LRs by proposing a modified version of Kwan's (2006) model. It has pedagogical implications for teaching Egyptian and apprentice researchers how to write more effective RA LRs. Future studies on a larger corpus of complete RAs written by Egyptian and international researchers in soft and hard sciences are needed to provide more generalizable findings.

Published: May 2021

Objectives: To assess the short term financial cost of the Covid-19 pandemic on private dental practice in Sri Lanka through a web-based questionnaire survey. Methods: An online web-based, self - administered questionnaire survey was conducted among Sri Lankan dental surgeons. Pre-tested questionnaire was used with close-ended questions, and questionnaire was designed to elicit data on the financial cost on private dental practice in Sri Lanka related to COVID-19 pandemic. Results: Response rate was 25%. Male and female responses were almost equal. Most of the respondents were in the 26 to 35 years age group (37.9%). Majority of the participants were only with BDS degree (53.7%). Out of those dental surgeons whose primary occupation was private dental practice, 50% were owners of the practice. Most of the practitioners have opened the practices during latter part of the COVID outbreak but treated a low patient volume. Total volume of patients managed by the majority of the respondents was less than 25% of the routine practice. Majority had an income less than 25% of the income during normal time. Similar number of participants expects/ does not expect the clinics will be back to usual income within another 6- 8 weeks. Interestingly, 55.1% of the participants did not find any financial difficulty due to the effects of Covid- 19 pandemic. Participants’ expectation of adjustment of number of patients and the income with their age category were statistically significant. The difference of their expectation for the government to help them according to the age was also statistically significant. Age of the respondents and expectation that the dental practices will be back to normal with normal number of patients and the income was statistically significant. More males have requested the banks to reschedule their loans. Conclusion: There are financial implications to the dental surgeons working in the private sector in Sri Lanka. Keywords: COVID 19; private dental practice; finance cost; dental surgeons

Titanium is a commonly used inert bio-implant material within the medical and dental fields. Although the use of titanium is thought to be safe with a high success rate, in some cases, there are rare reports of problems caused by titanium. Even though various recent advancement in the implant has been implicated in this era, still titanium is gold stranded among dental implant materials. In most of these problematic reports, only individual reports are dominant and comprehensive reporting has not been performed. This comprehensive article has been prepared to review the toxicity of titanium and its alloy materials in the field of dentistry.

Published: May 2021

Background: Tooth loss occurs due to periodontal disease, extensive dental caries, and fracture of teeth after a dento-alveolar trauma, cyst and tumours of odontogenic and non-odontogenic origin. Following loss of teeth, alveolar ridge resorption becomes an unwanted but unavoidable consequence. In order to restore the lost bone and replace the teeth with implants, ridge augmentation procedures are done. The present study aimed at restoring the class III ridge defect using piezosurgery with autogenous block bone graft procured from mandibular symphysis region. Materials and methods: A total number of 10 healthy patients with Class III ridge defect in maxillary anterior teeth region were enrolled for the study. The donor and defect sites were pre-surgically analysed using Cone-Beam Computed Tomography (CBCT), preclinical models and ridge mapping.The implant site width and height were assessed intra-operatively during the surgery and at re-entry after 6 months. The autogenous block bone grafts were procured from mandibular chin region using piezo-electric device and placed at the recipient site. At the 6 months re-evaluation, both clinical and radiographic parameters were assessed using CBCT of the recipient site. Implants were placed at two-stages and followed-up up to 6 months. Results: Clinical measurements showed that the mean horizontal bone gain and vertical bone gain was noted to be 3.21±0.24 mm and 2.18±0.32 mm respectively, by the end of 6 months follow-up. No major complications were presented at the recipient as well as donor sites. Piezoelectric surgery provided clean, bloodless field during the procedure and minimal post-operative discomfort to the patients. Conclusion: The results of the present study suggests that, class III ridge defects can be successfully augmented using piezo-surgery using autogenous bone grafting from the mandibular symphysis region. Also, delayed implant placement may provide satisfactory functional and aesthetic outcomes on the long term. Keywords: Ridge augmentation; chin graft; Piezosurgery; dental implants
Analysis of Lone Offenders with an Immigrant Background and a Prevention Model
Authors: Szabó András László
Published: May 2021

Lone offences are becoming more common across Europe among people with an immigrant background. In Hungary, the number of crimes related to migration and people with an immigrant background is small. The appearance of migration in the media, on the other hand, generates serious emotions. It can create groupings and trigger emotions in individuals to commit acts of wrongdoing. The phenomenon of migration has both positive and negative effects. One of the most frightening of the negative effects is the way it reshapes our thinking. This can be observed in the relationship between people with an immigrant background and the inhabitants of the host country. In my study I examine a lone perpetrator who emerges as a result of migration, focusing on the issue of prevention. I show how criminal policy and prevention models work, or do not work. At the end of the study, I outline a possible prevention model.
A Survey of the Organizational Situation of New Generations at a County Police Headquarters in Hungary
Authors: Tőzsér Erzsébet
Published: May 2021

Our organization is also affected by problems arising from the increasing presence of new generations in the labour market, such as differences in values, conflict situations and succession related difficulties. Therefore, a survey on the situation of new generations was carried out at the county police headquarters in the summer of 2020 (Tőzsér, 2020a). As part of this, an online questionnaire was conducted with the command staff (73 people) and the age group born from (after) 1 January 1990 (60 people). Both questionnaires included a structured interview part, but we also obtained quantifiable data - by evaluating 10 values from two perspectives. The results confirmed that there are large differences in terms of the perspective of the representatives of the older and younger generations. Young people are willing to meet only purposeful expectations that can be interpreted by them, and their loyalty is limited and based on reciprocity. Commander expectations for certain parameters, such as load capacity (resilience), may not prevail because they are not as important to young people. At the same time, leaders see the fast, efficient, and open-minded thinking of young people as an advantage. Overall, the study confirms the presence of a constant dynamic need for modernization within the organization.
FINANCIAL SECURITY IN THE CONTEXT OF ECONOMICS WELFARE
Authors: Robertas VAITKUS Robertas VAITKUS , VASILIAUSKAITĖ Asta
Published: May 2021

Abstract. Purpose – to describe financial security assurance models and assess the possibilities of using them to solve
problems to ensure economics welfare.
Research methodology – analytic, systematic, generalization and comparative methods are used in this article.
Findings – the content of the financial security concept is revealed at the microeconomic and macroeconomic levels,
while examining how the selection and implementation of appropriate financial security measures can contribute to
sustainable economic prosperity.
Research limitations – the consequences of the implementation of the financial security models analyzed in this article
are commented on assessing the peculiarities of one country’s national legal system.
Practical implications – appropriate solutions for maintaining financial security provided in the strategies of creating
economics welfare can help to decrease social exclusion, risks and negative effects of economic crises.
Originality/Value – in the article was formulated theoretical models of financial security assurance. The use of these
models or combinations of models at microeconomic and macroeconomic levels to incorporate financial security instruments
allows policy makers to have a universal toolkit in their arsenal. This enables not only to make decisions more
quickly, but also to solve the problems of ensuring economics welfare in a more systematic way.
MACROECONOMIC VARIABLES INFLUENCING LIFE SATISFACTION IN THE EU, AND ITS IMPACT ON EMIGRATION
Authors: LAURINAVIČIUS Alfredas , LAURINAVIČIUS Antanas , LAURINAVIČIUS Algimantas
Published: May 2021

Abstract. Purpose of the research is to analyse what variables influence subjective well-being (which is measured as
overall life satisfaction in the EU) and how it affects population’s decisions on emigration.
Research methodology – a correlation between several independent variables and overall life satisfaction is calculated.
Then, a correlation between overall life satisfaction and emigration rates is measured. Finally, regression equations are
constructed showing how some variables affect the other.
Findings – analysis helped to identify key variables which influenced overall life satisfaction and its impact on population’s
decisions on emigration. Those key variables include GDP per capita, income inequality and unemployment.
Research limitations – to analyse more social phenomena and not only the economic ones would contribute to research
development in the future. Moreover, analysis of dynamic aspects would provide deeper insight of relationships.
Practical implications – the analysis of emigration problem and the identification of its possible links with life satisfaction
will allow economists to assess a priori potential of various measures suggested in practice and, consequently,
will allow for more targeted formulation of the economic policy.
Originality/Value – scientific analysis of life satisfaction enables to have a new look on emigration problem in theory
and practice.

Authors: KAMRÁDOVÁ Lucie , SCISKALOVÁ Marie
Published: May 2021

Abstract. Purpose – the aim of the paper is to focus on the issue of corruption in public administration and to compare
this phenomenon in relation to the extent that affects individual spheres of state functioning, especially in public
administration.
Research methodology – the article will use mainly qualitative research methods to achieve the goal. The methodology
of the work is based in the first part of the analysis of the theoretical basis, which uses a comparison within the
European Union. The practical results of quantitative research through a questionnaire survey are presented in the final
part of the paper.
Findings – results can be used for both academic and social purposes and further research in this area.
Research limitations – the article sees its limits in a broader comparison from an international perspective.
Practical implications – the results can serve as a comprehensive material for further research, or an example of socalled
Good Practice, how public administration can manage the issue of corruption.
Originality/Value – the article in its essence deals with an original topic from the perspective of one country and performance
of public administration in the field of corruption.
THEORETICAL ASPECTS OF CULTURAL ECONOMICS CONCEPT
Authors: SKVARCIANY Viktorija , ASTIKĖ Kristina
Published: May 2021

Abstract. Purpose – the aim of the article is to present the concept of cultural economics upon analysing the scientific
literature and to single out the factors that influence the development of cultural economics.
Research methodology – analysis and synthesis of scientific literature. The articles published in CA WoS were analysed
in order to extract high-quality information on the topic of cultural economics.
Findings – after analysis of the scientific literature, the factors of cultural economics have been determined. They
are as follows: creativity; new technologies; consumer society; public authorities; artistic forms; media, information,
digitisation; local cultural identity; public sector approach to culture; theatre, cinema, museums, crafts; media, social
networks; the needs for a consumer society and culture; public sector funding for culture.
Research limitations – the main limitation of the current research is that the factors of cultural economics are distinguished
from the scientific literature. For more precise identification, the experts should be interviewed as well.
Practical implications – the distinguished factors could be used for measurement of the level of a country’s cultural
economics level.
Originality/Value – the article summarises
THE RELATIONSHIP BETWEEN CREATIVITY, IDENTITY, PLACE, AND COMMUNITY RESILIENCE: THE RENAISSANCE OF CLARKSDALE, MISSISSIPPI, UNITED STATES
Authors: Waddell Terrie
Published: May 2021

This paper examines the relationship between creativity, identity, and place for the small economically challenged Delta City, Mississippi of Clarksdale, United States, a once prosperous manufacturing and farming community. Promoted as the Delta’s epicenter of blues music, over the last twenty years key business stakeholders in the city’s renaissance have been committed to developing local and international awareness of Clarksdale’s historic architecture, culture and blues heritage. It was not until 2008 when economist and town planner John C. Henshall formulated the Downtown Clarksdale Action Plan for Economic Revitalization that the city secured a comprehensive guide to growth. The plan was designed to support downtown infrastructure and tourism through a creatively based strategy, dependent on the tourism potential of blues performances and the imaginative efforts of those invested in the ongoing renewal project. Drawing on incentives aligned with the plan’s objectives, and seven semi-structured interviews with local entrepreneurs and revitalization participants, this paper examines the connection between collaborative creativity, collective identity, connection to place, and community resilience.
Latitude Variation of Flux and Impact Angle of Asteroid Collisions with Earth and the Moon
Authors: Robertson Darrel , Pokorný Petr , Granvik Mikael , Wheeler Lorien , Rumpf Clemens
Published: May 2021

Flux and impact angles were calculated for asteroid collisions with Earth and the Moon, using the latest population models for the distribution of near-Earth objects (NEOs) and precession models to determine the impact probabilities. The calculations predict that the flux of impacts to the poles for Earth is 22% greater than the flux at the equator, and 55% greater for the Moon. Impacts near the equator typically have shallower impact angles with a mode near 30° above the horizontal. Conversely, impacts near the poles are typically steep with a mode close to 65°. Our new analysis updates the previously published results by Le Feuvre & Wieczorek incorporating: (1) an updated debiased distribution of NEOs, and (2) updated collision probabilities that account for Lidov–Kozai precession. The new impact distributions provide an important update to risk models, showing a 7% increase in average population risks from sub-300 m impactors, compared to previous atmospheric entry distributions, mostly due to faster impact velocities.

Published: May 2021

Pour faire face à la période de confinement, le groupe d’intervision est sollicité dans sa fonction de soutien. Conscient de l’impact de la crise de la Covid-19 sur les individus, les organisations et la société dans son ensemble, le groupe se mobilise pour garder traces des mouvements qui l’ont traversé. Un projet d’écrit est envisagé. Le processus d’écriture va se décliner en trois phases : la mise en forme de notes, l’écriture d’un article, la proposition d’une contribution à la revue Connexion . Nous témoignons ici des processus à l’œuvre au sein d’un groupe d’intervision qui transforme sa centration initiale pour inclure une nouvelle tâche, celle de l’écriture.
Comment rompre les logiques d’isolement autour de l’accompagnement… de la parentalité ? Action-recherche auprès des REAAP
Authors: Prisca Martin Désirée , Garcia Nieves , Rivière Maud , Schwartz Agnès
Published: May 2021

Cet article présente les résultats d’une action-recherche menée auprès de onze structures d’Île-de-France apparentées au réseau d’écoute, d’appui et d’accompagnement des parents ( reaap) . Après avoir restitué de fortes lignes de tensions institutionnelles au sein de ces réseaux, nous cherchons à construire des repères théorico-cliniques pour témoigner des spécificités contemporaines de l’expérience de la parentalité. Il nous est apparu que les espaces de rencontres tels que les reaap proposent aux parents une groupalité à la fois désirée et redoutée, tant elle confronte au risque de devoir se mesurer à des représentations idéalisées de la parentalité, déjà présente chez le sujet. Les fonctions éducatives, jadis assurées par l’institution familiale, sont aujourd’hui dévolues à l’individu seul ; en témoigne l’évolution sémantique de la notion de famille à celle de parentalité. L’isolement semble être devenu une condition paradigmatique de l’être parent, qui s’étend aux professionnels et même aux structures.
