Governança dos planos de desenvolvimento local no município de Breves: impactos sobre as políticas públicas de 2000 a 2015 (Paper 388)
Authors: Furtado Márcia Nemer , Da Silva Fábio Carlos
Published: March 2023

O escopo do artigo é o de analisar a governança dos planos de desenvolvimento local e suas implicações sobre as políticas públicas no município de Breves no período de 2000 a 2015. Para o desenvolvimento da análise proposta utilizou-se o método de abordagem indutivo, o procedimento estatístico, bem como técnicas de pesquisa bibliográfica, documental e de campo. A análise aborda, principalmente, as temáticas da governança, das políticas públicas de desenvolvimento local e de planejamento. A Governança representa um processo de promoção de ações socialmente justas e ampliação da participação do cidadão nos processos decisórios. As políticas públicas de desenvolvimento local, por seu turno, representam um processo endógeno de mudança, enquanto o planejamento de desenvolvimento local, aqui discutido, objetiva desenvolver políticas públicas com vistas a alcançar o bem público. Em contraposição às bases para uma boa governança, os resultados indicam que a gestão no Município de Breves, no período em pauta, não impactou efetivamente sobre as políticas públicas locais. Conclui-se, pois, afirmativamente quanto à hipótese de que a ausência da boa governança contribui para a não efetividade de políticas públicas, haja vista o referido sistema de planejamento limitar-se a documentos referentes aos Planos de Desenvolvimento Local previstos e, na maioria das vezes, não executados, minimamente conhecidos e, consequentemente, de pouco impacto sobre as políticas locais.Palavras-chave: Governança. Políticas Públicas. Planos de Desenvolvimento Local.
As mudanças no uso e cobertura da terra e o comportamento hidrológico da bacia do rio Capim (Paper 390)
Authors: Dias Gustavo Francesco De Morais , De Lima Aline Maria Meiguins , Santos Milena de Nazaré Silva
Published: March 2023

A bacia do Rio Capim localiza-se no nordeste do Estado do Pará e é marcada por intensos graus de antropização, neste contexto estudos indicam que as implicações ocasionadas pelas mudanças no uso e cobertura da terra têm afetado o comportamento hidrológico de bacias hidrográficas. O estudo teve como objetivo relacionar o comportamento da vazão com as mudanças no uso e cobertura da terra da bacia hidrográfica do rio Capim, para os anos de 2004, 2008, 2010 e 2014. A fim de se identificar a proporção das classes na bacia e nas Áreas de Proteção Permanentes (APP’s) utilizou-se os dados de uso e cobertura da terra do projeto TerraClass; para avaliação do comportamento hidrológico analisou-se a vazão média anual e os trimestres de maior e menor vazão, além do comportamento da precipitação no período de 1983 a 2014. Os resultados apontaram para uma redução na classe floresta para a bacia do rio Capim, e aumento das classes pastagem e agricultura, porém nas APP’s identificou-se um aumento da classe floresta no período 2004 a 2014. Espera-se que os indicativos apresentados na pesquisa auxiliem a interpretação dos fenômenos espaciais que modulam o cenário hídrico e ambiental existente na região.Palavras-chave: Estudo da paisagem.

Condições higiênico-sanitárias em casas produtoras de farinha de tapioca: uma análise no distrito vila de americano, município de santa Izabel do Pará (Paper 394)
Authors: França Samara Avelino De Souza , Norat Maria de Valdivia Costa
Published: March 2023

E Considerando que as casas produtoras de farinha de tapioca podem ser afetadas pelas condições sanitárias no domicilio ou no seu entorno, objetivou-se analisar suas condições higiênico-sanitárias no distrito Vila de Americano, município de Santa Izabel do Pará. A coleta de dados consistiu de entrevistas com perguntas fechadas e observações in loco. Verificou-se que a maioria dos produtores são homens, com idade de 31 a 45 anos, com ensino fundamental incompleto, cujas casas de farinha são de madeira, possui água canalizada, os resíduos são coletados pela Prefeitura e os dejetos seguem para fossas rudimentares ou para a sarjeta, com piso, teto e paredes relativamente conservados. De modo geral, as instalações estavam limpas, embora não tenha se verificado lavatórios e lixeiras nas suas dependências. A maioria dos manipuladores não utilizava vestimenta adequada, nem equipamentos que previnam contaminação da farinha, como luvas, toucas e máscaras. Portanto, trata-se de condições relativamente precárias, cuja implementação de ações (disponibilização de um Manual de Boas Práticas de Fabricação específico para a farinha de tapioca; apoio e incentivo governamentais para melhoria físico-estrutural das casas e linhas de credito; educação sanitária para os produtores e seus funcionários) são fundamentais para garantir a qualidade dos alimentos e a segurança alimentar.Palavras-chave: Condições higiênico-sanitárias.

La individuación del cuerpo migrante: una reflexión acerca de la identidad en las masas desarraigadas
Authors: Forero Sosa Andrés
Published: March 2023

"Una reflexión frente a la proyección e impacto social que puede tener un colectivo patente del desarraigo; como es el grueso migrante, es completamente necesaria en el contexto actual. Todo ello a raíz de las crecientes tensiones y brechas socioculturales, así como económicas y humanitarias que escinden; y han escindido, la sociedad a nivel mundial en los últimos años. Superando los problemas de cariz político, las siguientes ideas se centran en una revisión antropológica sustentada a parir de la narratividad y de la propuesta ricoueriana de la Identidad narrativa. Por lo demás, revisar las ideas de los pensadores que se enfrentaron a finales del siglo XIX y comienzos del siglo XX al fenómeno desbordado de las masas en conjunción con los desarraigados migrantes, es una tarea que se realiza juiciosamente en el siguiente escrito. Una revisión de la identidad de las masas desarraigadas, del alcance de la propuesta ricoueriana y de la noción de narración frente a la crisis, son los puntos centrales del artículo en lo que sigue."

El trabajo realizado permite posicionar al taller como un articulador de saberes empíricos y expertos para la generación de acciones transformadoras a partir de las realidades concretas, de modo que se promueva la creación, transferencia y apropiación del conocimiento para la innovación social, con un impacto positivo en los territorios de esa aún desconocida Colombia profunda.
La proyección social, prospectivas e implicaciones desde el lasallismo
Authors: Rivera Venegas Juan Carlos
Published: March 2023

El artículo propone, en primera instancia, una aproximación a una comprensión del sentido de la proyección social en el lasallismo; este ejercicio se complementa con una adaptación de los criterios de identidad para la vitalidad de las obras educativas lasallistas, orientando así el enfoque del mismo, fieles a la espiritualidad heredada. Posteriormente, se plantean unas prospectivas de la proyección social en la Universidad de La Salle, Bogotá. Pues dadas las fuertes tensiones que vive hoy el planeta, los significativos cambios demográficos, la ampliación de la desigualdad e insatisfacción social, las nuevas condiciones de polarización económica, política, etc., entre otros, es imperioso buscar responder desde la educación a las necesidades actuales, con innovación y de manera integral, con particular atención a quienes viven en las periferias, y a quienes se encuentran en ‘la frontera’. Se esbozan, entonces, algunas ideas del planteamiento lasallista para aportar al cambio.

Optimum currency areas: State of research, the European Monetary Union
Authors: Drossart-Demond Alexander Lucian
Published: March 2023

The present paper deals with optimum currency areas (OCA). Its main goal is to give a synthesis of the central research areas in this field and provide a link to the real-life example of the European Monetary Union (EMU). Overall, the paper will possibly uncover potential areas for further research, and thus may be able to serve other researchers. The article illustrates the original OCA theory by Robert Mundell and further important research built upon it. The OCA criteria resulting from the foregoing research are then placed aside the actual Maastricht criteria set up by the European Union, necessary to fulfil for joining the eurozone. The question of whether these criteria are even necessary is examined alongside the topic of endogeneity, which is a relatively new field of research in the OCA field. Lastly, the pros and cons of joining a single currency area are analyzed, before the author provides suggestions for potential future research.
Too big, too small: Why the size of the FOMC does matter
Authors: Mroziewicz Krzysztof
Published: March 2023

The present article discusses the effectiveness of the decision-making body of the Federal Reserve System (Federal Open Market Committee, or FOMC for short) in the context of management. It focuses on the size of the FOMC as a group larger than the optimum of the group’s effectiveness (depending on the study, the optimum size of the group should be three to eight or five to seven people). The article also discusses the potential negative consequences of too large a group and ways to improve group decisions. The last part of the paper includes an explanation of the decision-making structural composition, and thus partially answers the question of why the FOMC consists of seventeen members, and its decision-making composition of twelve.
Pro-environmental or pro-social: Which motivation is stronger in the case of charity retailing engagement?
Authors: Borusiak Barbara , Kucharska Barbara
Published: March 2023

The aim of the study is to examine the intention to engage in charity retailing using the norm activation model which has been widely used to predict people’s altruistic and pro-social behavior (De Groot and Steg, 2009, 425–449). Pro-social behavior refers to a person’s action that is intended to help other people and consists of a broad range of helping, sharing, and cooperating behaviors. Three forms of engagement in charity retailing were taken into account: buying at a charity shop, volunteering in a charity store, and donating. The current study was conducted in 2019 using the CAWI method on 766 Polish students coming from 16 universities; for data analysis, SEM was applied. We tested two variants of the model. In the first one we connected personal norm, awareness of consequences, and ascription of responsibility with the context of the natural environment protection, whereas in the second the same variables were connected with helping people in general. The findings show that the norm activation model may be applied as a mediator model for explaining intention to engage in shop charity. Both tested models were positively verified — all relations but one were proven to be statistically significant. The only relation which turned out to be statistically insignificant was the relation between awareness of consequences and personal norm. The results show that environmental context increased the strength of the relations between the analyzed variables.
Supporting self-esteem and self-acceptance in commercial brand campaigns created during a pandemic: Social and marketing aspects
Authors: Daszkiewicz Magdalena
Published: March 2023

Commercial brands are increasingly running campaigns supporting self-esteem and self-acceptance in response to social events, trends, and expectations related to social responsibility. By conducting such campaigns, brands try to pursue social and marketing objectives. The pandemic period was associated with increased problems and strengthening of social trends regarding self-acceptance and self-esteem. Therefore, the importance of actions related to these issues is of particular social relevance today. The pandemic conditions may have been reflected in the content and features of advertising campaigns and the associated consumer expectations and attitudes. In recent studies, far too little attention has been paid to intentional supporting self-esteem and self-acceptance in commercial brand campaigns. The article responds to an identified need for research concerning key messages and characteristic features of contemporary self-esteem advertisements, which may be linked to the specific social context. The important research issue is also the marketing and social value of advertising supporting self-esteem and self-acceptance. The article aims to identify key messages and features of commercial brand campaigns created during the pandemic that support self-esteem and self-acceptance. It also attempts to assess such campaigns in terms of their social and marketing value. These objectives were accomplished by using qualitative and quantitative methods. The research procedure involved three stages: desk research based on studies from the pandemic period regarding self-acceptance and self-esteem issues, a collective case study of campaigns of three brands supporting self-esteem and self-acceptance and a diagnostic survey using an online questionnaire on the consumer perception of such campaigns and their value judgments resulting from expectations, motives, and impact assessments. The research is placed in the context of a pandemic, but the trends identified, key messages and features of the self-esteem campaigns, and assessment dimensions may remain relevant in the future.

Published: March 2023

Artykuł poświęcony jest pandemii na Ukrainie wywołanej przez wirus SARS-CoV-2. Celem pracy jest analiza wyników badania studentów na temat pandemii opartego na autorskim kwestionariu-szu. W artykule przedstawiono kwestie organizacji badania, przeprowadzono analizę osobistego i psychologicznego postrzegania pandemii przez respondentów, oceniono środki legislacyjne i wykonawcze stosowane na Ukrainie w celu ograniczenia pandemii i przeciwdziałania jej rozprzestrzenianiu się. Respondentami w badaniu byli studenci kierunku rachunkowość i podatki na Wydziale Ekonomicznym Lwowskiego Uniwersytetu Narodowego im. Iwana Franki. Spojrzenie studentów tej specjalności jest ważne, ponieważ w przyszłości będą oni dostarczać informacji potrzebnych do podejmowania decyzji podmiotom gospodarczym, co jest istotne w sytuacjach kryzysowych. Ankieta pisemna została przeprowadzona zdalnie po drugim miesiącu trwania pandemii. Kwestionariusz zawierał dwanaście pytań dotyczących postrzegania pandemii i sposobów jej przezwyciężenia. Wyniki badania zostały przeanalizowane w świetle wydarzeń następujących w ciągu roku po przeprowadzeniu badania. Wartością doświadczenia badawczego jest możliwość porównania wyników badania z późniejszymi wydarzeniami i działaniami naprawczymi rządu prowadzącymi do ograniczenia negatywnych skutków pandemii i innych zagrożeń w przyszłości.
Zmodyfikowany indeks rozumienia i stosowania marketingu jako instrument oceny aktywności marketingowej aptek ogólnodostępnych w Polsce
Authors: Żak Konrad
Published: March 2023

Aktywność marketingowa jest istotnym aspektem prowadzenia działalności operacyjnej podmiotów świadczących usługi farmaceutyczne. Wzbudza jednak wiele kontrowersji z uwagi na trudności ze zrozumieniem i z właściwym zastosowaniem poszczególnych instrumentów marketingu. To z kolei powoduje, że pojawiające się patologie w procesie świadczenia usług farmaceutycznych są utożsamiane z marketingiem, który według niektórych przedstawicieli środowiska farmaceutów służy wyłącznie potęgowaniu sprzedaży dla zysku. Takie zawężenie roli marketingu wskazuje, że nie jest on należycie rozumiany i odpowiednio stosowany w praktyce aptecznej. Marketing należy rozumieć wielowymiarowo, albowiem jest kategorią złożoną — wieloaspektową, stąd jest różnie deﬁniowany i rozumiany. Owe wieloaspektowość i wielowymiarowość podejścia do marketingu przekładają się na realizację działalności operacyjnej aptek ogólnodostępnych, która różnie rozumiana, nie zawsze jest stosowana lege artis. Mając na uwadze pojawiające się ograniczenia we właściwym rozumieniu i odpowiednim stosowaniu instrumentów marketingowych, stworzono koncepcję indeksu rozumienia i stosowania marketingu, która przez autora została rozszerzona i zmodyﬁkowana (do wersji 2.0), aby można ją było zastosować w praktyce aptecznej. Celem artykułu jest przedstawienie idei koncepcji zmodyﬁ kowanego indeksu rozumienia i stosowania marketingu, który to indeks stanowi system wielopoziomowej i wieloaspektowej oceny rozumienia i stosowania marketingu w aptece. Istotą tego indeksu jest wielowymiarowa, ważona ocena znajomości zasad stosowania marketingu oraz aktywności marketingowej realizowanej w toku prowadzonej działalności operacyjnej. Zmodyﬁkowany indeks rozumienia i stosowania marketingu pozwala na obiektywizację i minimalizację ograniczeń wpływających na ocenę aktywności marketingowej aptek, co przekłada się na racjonalizację klasyﬁkacji aktywności zarządzania marketingowego.

Authors: Badeckiy Aleksandr , Medved' Oksana
Published: March 2023

Purpose: In the frames of ongoing digital transformation of transport complex in a whole and railway transport in particular, to give brief analytical characterization of being developed digital platforms and services. To consider promising technologies that are either at launch stage or on the way to the peak of overpriced expectations as to technological hype cycle of Gartner Research Company. To give an example of unified knowledge base as a basis of digital platform for multimodal transportation. Methods: Methods for visual structuring of information were used, in particular, mental maps (intellect-maps). To represent subject area ontology, a semantic network was used as a method for knowledge representation. Results: The pursued analysis of being developed and existing digital platforms and services has shown that besides data, there should lie at their basis more complex informational units — an active knowledge. This requires the method of data integration from disparate sources, their integration and circulation as within one industry as well as between various industries in order of knowledge generation and spread. In view of work specifics of transport various kinds, participating in multimodal transportations, the subject area, uniting all kinds of transport, should be chosen for this. The application of "cargo transportation" subject area has been justified by virtue of which, it is necessary to create management system of cargo flows on railway transport. Ontology fragment, describing "cargo transportation" domain for railway transport, has been worked out. Practical significance: The necessity of applying active knowledge to create autonomous intellectual productions on transport is shown. The use of knowledge bases, established on ontologies, will allow to raise the level of interaction of transport various kinds in "narrow" places during cargo transshipment as well as to expand the range of services, provided to customers.

Bridge or Barrier? Religious Identification’s Role in Shaping Attitudes toward Immigrants and Immigration in the European Context
Authors:   , Benoit Verena
Published: March 2023

Societal and political changes in European countries have led to a renewed scholarly interest in the relationship between individuals’ religious identification and attitudes toward immigrants and immigration. However, previous research on this topic did not reach a consistent conclusion. It remains unclear whether greater religious identification acts as ‘bridge’ and results in positive attitudes or as a ‘barrier’ which results in negative attitudes toward immigrants and immigration. The present cumulative dissertation dedicates itself to addressing this ambiguity. Multivariate statistical analyses of survey data have come to at least three major conclusions for individuals’ attitudes: First, the attitudes depends on the values religious individuals support and how threatened they generally feel by immigrants, not only on how strongly they identify with their religious group. Second, the attitudes differ in the context of external shocks that highlight the salience of religion and immigration. Third, religious identification does not only shape the attitudes of majority group members within the host population but also of minority group members, especially Muslim immigrants.

The curve of the trajectory of the subsidence of the earth's surface is divided by characteristic points at different stages of subsidence of the earth's surface. Such stages include: the beginning of the displacement of the earth's surface, the active stage of displacement, the end of the active stage and the attenuation of the processes of subsidence of the earth's surface. According to the goal and the design scheme, on the basis of experimental data, we determined the parameters corresponding to the location of a point on the earth's surface where it began to settle. In relation to the scheme under consideration, three well-known dependencies were analyzed to describe the subsidence curve of the earth's surface: the exponential equation, the hyperbolic tangent function, and the logistic curve. Based on them, it was established that the main influencing factor determining the boundary of the dynamic half-mold is the depth of mining operations, and the boundary angles are practically independent of this parameter.

Online education has significantly gained popularity due to new technology and more importantly, the growing impact of the digitalization of the economy. Despite its prominent advantages such as accessibility, affordability and flexibility, the effectiveness of online education is still a constant debate and needs extensive investigations in different research contexts. This study aimed to evaluate the effectiveness of online learning in comparison to traditional learning in the context of English language teaching. This descriptive study was undertaken with learners of English as a foreign language (EFL) in English proficiency preparation classes, employing an online questionnaire together with final scores of proficiency tests. The results revealed that the participants had relatively positive perceptions towards online learning in all four aspects: course content, teachers, learning environment and course supports. The significant finding was that when comparing the final results of the VSTEP exams, the online learners generally were able to perform better than the learners in traditional classrooms, though the difference was not largely remarkable. Online education in the new normal will continue to excel and the effectiveness of this learning mode certainly needs further investigation from different perspectives.

UV induced photoluminescence of organosilica films with ethylene and benzene bridging groups in their matrix and terminal methyl groups on the pore wall surface is studied to reveal optically active defects and understand their origin and nature. Careful selection of the film’s precursors and conditions of deposition and curing, analysis of chemical and structural properties led to the conclusion that luminescence sources are not associated with the presence of oxygen-deficient centers, as in the case in pure SiO2. It is shown that the sources of luminescence are the carbon-containing components that are part of the low-k-matrix, as well as the carbon residues formed upon removal of the template and UV induced destruction of organosilica samples. A good correlation between the energy of the photoluminescence peaks and the chemical composition is observed. This correlation is confirmed by the results obtained by the Density Functional theory. The photoluminescence intensity increases with porosity and internal surface area. The spectra become more complicated after annealing at 400 °C, although Fourier transform infrared spectroscopy does not show these changes. The appearance of additional bands is associated with compaction of low-k matrix and segregation of template residues on the surface of the pore wall.

In the recent years, biochar has emerged as a remarkable biosourced material for addressing global environmental, agricultural, biomedical, and energy challenges. However, the performances of biochar rest in part on finely tuning its surface chemical properties, intended to obtain specific functionalities. In this review, we tackle surface treatment of biochar with silane and other coupling agents such as diazonium salts, titatantes, ionic/non-ionic surfactants, as well as nitrogen-containing (macro)molecules. We summarize the recent progress achieved mostly in the last five years, and correlate the nature and extent of functionalization to eye catchy end applications of the surface engineered biochar.
Gas-Water Characteristics of Tight Sandstone in Different Charging Model in Xihu Sag, East China Sea Basin

Published: March 2023

Reservoir in the Central Structural Zone of the Xihu Sag is the Huagang Formation, dominated by natural gas reservoirs, and the reservoir in the Western Slope Zone is the Pinghu Formation, dominated by light oil and wet gas. In this paper, the Gas Drive Water Displacement- Magnetic Resonance Imaging (GWD-MRI) experiments are used to simulate the charging characteristics of the sandstone migration layer. The centrifugal- Magnetic Resonance (Cen-NMR) experiments simulate the short-term fast trap charging process, and the Semi-Permeable Baffle (SPB) charging experiment simulates the slow trap accumulation process. Studies have shown that there is a start-up pressure for the migration layer charging, and the start-up pressure of the core with a permeability of 0.3mD is about 0.6MPa. Experimental simulations have confirmed that there is a front zone with changed water saturation, with a width of about 1-1.5cm. The migration layer charging mainly has two actions, drive effect and carry effect. The drive effect reduces the water saturation to 70%-80%, and the carry effect can still reduce the water saturation by 5%-10%. The water saturation of rapid charging is mainly affected by the petro-physical. The porosity is high, the water saturation is low. The water saturation decreased significantly with the increase of centrifugal force when the centrifugal force is smaller. If the centrifugal force is greater than 0.8 MPa, the water saturation decreases slowly. The water saturation of the trap slowly charging is basically maintained at 40%-50%, which matches the water saturation of the airtight coring from 40%-55%, the petro-physical do not affect the final water saturation.
