Opis:
Research background: Economic freedom plays a pivotal role in ensuring the progressive productivity of banks. It fosters a favorable economic climate and acts as a catalyst for the generation of innovative ideas. In addition, economic freedom allows new domestic and foreign entrants in the banking sector which leads to increased competition as well as wider range of product offerings and thus potentially affect bank efficiency. Purpose of the article: This study aims to identify the effects of regulatory efficiency and market openness in terms of economic freedom on the bank’s productivity at three income levels: lower-middle, upper-middle, and high-income economies. Methods: A sample of 15 countries are included in the study from differing income levels. The study uses the data envelopment analysis (DEA) based Malmquist productivity index (MPI) approach to measure banks’ productivity. This non-parametric approach measures the relative efficiency of banks by considering the production change while taking into account technical efficiency change and technological change in order to capture a comprehensive view over time. Then, regression analysis was performed utilizing the ordinary least squares (OLS) approach, fixed effect (FE), and random effect (RE) panel multiple regression estimation methods are utilized to measure economic freedoms and other determinants’ effect on banks’ productivity change over time.  Findings & value added: The results show that banks in high-income economies are more productive and have higher growth rates than those in upper- and lower-income economies. Furthermore, starting, obtaining permits, and closing businesses under business freedom have a detrimental effect on banks’ output, whereas the effects of labor freedom on employing, managing, and supervising staff members have a substantial favorable impact on banks’ productivity. Moreover, financial freedom and investment freedom under the market openness dimension negatively influence banks’ productivity. Government intervention is required to introduce regulations that allow foreign countries to provide labor at lower wages, introduce tax allowances, and control inflation rates. Thus, the empirical results of this study will benefit regulators and policymakers in developing a system and plan to increase banks’ productivity based on indicators of business, labor, financial, and investment freedom.

Opis:
Objectives 1,3-Butadiene (BD) exposure’s link to leukemia is under regulatory scrutiny. The assessment methods for BD exposure risks have evolved from early animal and limited human studies to advanced exposure-response modelling with comprehensive quantitative data. The objective of this study is to explore the nuances of exposure-response modelling, investigating how various statistical methods have influenced the quantification of exposure-response relationships. Material and Methods Although this study was not conducted as a formal systematic review, a search was performed in Medline/Pubmed to identify all human studies on leukemia risk assessment for BD exposure. This search included articles written in English. The electronic search spanned from inception of records until July 23, 2023, using the search term: “butadiene AND (leukaemia OR leukemia OR myeloid OR lymphoid)” and was restricted to human species. Focusing on the synthetic styrene-butadiene rubber (SBR) industry cohort study conducted by the University of Alabama at Birmingham, USA, this review evaluates various statistical models and factors influencing exposure-response modelling. Results Peak exposures to BD may be more influential in the dose-response relationship than cumulative or long-term exposure. The authors recommend utilizing β-coefficients derived from the latest SBR study update, employing Cox proportional hazard modelling, non-lagged and non-transformed cumulative BD exposure, and adjusting for age and peak BD exposure. The study reveals that statistical model selection has a limited impact on the calculated dose-response effects. The significant variation in estimated cancer mortality values arises from additional assumptions needed for metrics like the excess leukemia risk or the occupational BD effective concentration. Conclusions In conclusion, this study provides insights into exposure-response modelling for BD exposure and leukemia mortality, highlighting the importance of peak exposures. The recommended statistical approach offers a reliable basis for regulatory risk assessment and public health population metrics.

Opis:
Pandemia COVID-19 wpłynęła na funkcjonowanie wielu grup społecznych w Polsce. W publikacjach naukowych dotyczących tej problematyki w dziedzinie nauk społecznych koncentrowano się przede wszystkim na sytuacji organizacji w kontekście pracy zdalnej i na przemianach technologicznych związanych z nowymi wyzwaniami wynikającymi z izolacji. Przeprowadzone przez Autorów niniejszego opracowania studia literaturowe pozwoliły zidentyfikować lukę w wiedzy polegającą na niewielkiej liczbie publikacji dotyczących wpływu izolacji na osoby z niepełnosprawnościami, a szczególnie na temat zmian układu sił w otoczeniu dalszym, które wpływają na życie tej grupy społecznej. Problem badawczy sformułowano w postaci pytania: Jakie są konsekwencje izolacji osób z niepełnosprawnościami z perspektywy prawnego, ekonomicznego, społecznego i technologicznego wymiaru pandemii? Wyniki analiz ukazały, że pandemia COVID-19 stanowiła wyzwanie dla systemu ochrony zdrowia osób z niepełnosprawnościami oraz doprowadziła do obnażenia wybranych słabości systemu i materializacji ryzyka dla tej wrażliwej grupy społecznej. W badaniach wykorzystano takie metody jak: przegląd literatury, analizę PEST (analiza otoczenia dalszego: Political, Economic, Social, Technological) oraz metodę analizy i syntezy.
The COVID-19 pandemic impacted the functioning of many social groups in Poland. Scientific publications addressing this issue in the field of social sciences focused primarily on the situation of organisations in the context of remote work and technological transformations associated with new challenges arising from isolation. The literature review conducted identified a knowledge gap, characterised by a limited number of publications addressing the effects of isolation on people with disabilities, particularly the shift in power dynamics in the broader environment that affects the lives of this social group. The research problem was formulated in the form of a question: What are the consequences of isolation for people with disabilities from the legal, economic, social, and technological dimensions of the pandemic? The study results revealed that the COVID-19 pandemic posed a challenge to the healthcare system regarding people with disabilities. The research methods included literature review, an opinion survey, tools, PEST analysis, and statistical analysis.

Opis:
Esta investigação tem como objetivo refletir sobre a cobertura fotojornalística de mulheres que, por determinada lógica, podem ser consideradas produtoras de enquadramentos “não oficiais” de uma realidade política e social, quer dizer, de enquadramentos que de alguma maneira rompem com aquilo que seria autorizado pelo Estado vigente, de acordo com o pensamento proposto por Judith Butler. A perspectiva epistemológica dos Estudos de Gênero e o embasamento teórico da História das Mulheres colaboram para o desenvolvimento da reflexão que parte do período histórico da ditadura militar brasileira, iniciada em 1964, e que estabeleceu a censura e o cerceamento de direitos sobre a sociedade civil, mas também recaiu muito fortemente sobre profissionais da imprensa do país. Ao longo da discussão, são apresentados trechos de entrevistas, algumas realizadas e interpretadas a partir da metodologia da História Oral, o que permitiu observar que determinadas experiências fotográficas operam como uma espécie de resistência à imagem que se tentava construir à cerca do país. Acredita-se que tais produções podem consideradas formas de tencionar e desafiar imagens que se tornaram ícone de determinados períodos políticos e que seguem em disputas constantes pelo posto da “verdadeira” história.
The research its about women’s photojournalistic coverage which reflect by a certain logic that can be considered producers of non-regulatory frameworks of a political and social real- ity. These are frameworks that somehow break with what would be authorized by the ruling state, according to the thinking proposed by Judith Butler (2015). The epistemological perspective of Gender Studies and the theoretical basis of Women's History contribute to for this reflection, which focuses on two historical periods marked by censorship and hostility: the Brazilian military dicta- torship (1964 - 1985), a time when the curtailment of civil society rights was established, falling very heavily on the country's press; and the period comprising the presidential mandate of Jair M. Bolsonaro (2018-2022). It was an episode in recent history that recalls characteristics of the 1970s, such as the encouragement of authority, conservatism and violence. Throughout the discus- sion, excerpts from four interviews are presented, one of which (Beth Cruz) came from a more extensive study using Oral History methodology (Schmitt, 2022), which allowed us to observe that certain photographic experiences operate as a kind of resistance to the image that has been done and continues to be constructed about the country. In addition, we present accounts by Gabriela Biló, Elvira Alegre and Nair Benedicto. All the interviews was collected from academic publications available online: the first two are from university laboratories and the third from a scientific journal. It is believed that the images produced by these women can be seen as a way of challenging images that have become icons of certain political periods and that are still in constant dispute for the position of "true" history.

Opis:
The maritime industry has begun to look into autonomous ships as an alternative to conventional ships due to growing pressure to reduce the environmental impact of maritime transportation, to increase safety, to mitigate the growing challenges in recruiting seafarers, and to increase profit margins. There is a lot of research on the challenges and feasibilities of an autonomous ship. However, there is less discussion on the transition from manned to unmanned ships and the tasks that are feasible to automate before the whole ship is unmanned. This paper investigates the technical and regulatory feasibility of automating different tasks for different operational phases for a large cargo ship. This study shows that a fully unmanned cargo ship is not feasible today, but that some tasks can be automated within the next five years.

The purpose of the study was to establish dependence of sunflower productivity on hybrid plasticity under the climatic conditions of the Steppe zone and effectiveness of growth-regulators on the basis of the analysis of differentiation of a vegetation index. The research on the development and productivity of different sunflower hybrids under the natural-climatic conditions of the Steppe zone of Ukraine was conducted in the years of 2019 (medium-wet), 2020 (dry) and 2021 (wet). Spatio-temporal differentiation of the vegetation of sunflower hybrids was established on the basis of calculation of a normalized difference vegetation index (NDVI) using the data of the decoded space images of Sentinel 2. Cartographic and grapho-analytical materials reflecting the reaction of plants to natural-climatic conditions and multifunctional growth-regulators were obtained. The dependence of the reaction of sunflower hybrids to multifunctional growth-regulators on their plasticity in response to the natural-climatic conditions of the Steppe zone was established. There was a weak reaction to application of growth-regulators of the sunflower hybrids Oplot and P64HE133 which are characterized by a high level of plasticity in response to the natural-climatic conditions of the Steppe zone. It was proven that the application of the biological preparation Helafit Combi exceeded the level of agrocenoses productivity in comparison with the chemical preparation ArchitectТМ by 1.1-5.4%. It was established that foliar treatment with growth-regulators led to a decline in water uptake by the sunflower hybrids by 1.2–10.0% in the dry year, by 3.8–8.6% in the medium-wet year and by 3.7%–21.9% in the wet year. There was a significant reduction in the level of water uptake by the hybrid Hector – by 7.7–10.0% and the hybrid 8KH477KL – by 1.2–21.9%. The research results are the basis for forecasting the development of sunflower hybrid crops with further measurement of the crop productivity that allows establishing a probable level of efficiency of sunflower hybrid production by agricultural producers under the climatic conditions of the Steppe zone.

Opis:
The most common solutions for rocket engines are the single operation point (thrust level) units. Oxidiser and fuel mass flow rates and the oxidiser-to-fuel mass flow rate ratio (OFR) are some of the determinants of the thrust level. Based on these, planetary ascent and descent; space rendezvous; orbital manoeuvring, including orientation and stabilisation in space; hovering, hazard avoidance during planetary landing; and ballistic missile trajectory control propulsion systems could use throttleable liquid engines. Several engine throttling methods, such as supply pressure variation and variable injector area, can be applied. Among others, a cavitating venturi propellant regulatory valve is one of the most promising throttling method. This type of valve can provide steady mass flow, despite the downstream pressure disturbance (i.e. from the combustion chamber), which sustains a stable engine thrust as the mass flow is kept. The article presents the valve sizing method, design and prototype test results of the cavitating venturi valve that has potential for utilisation in a deep throttling rocket engine. Mass flow stability and repeatability are presented for valve operating points in the 10%-110% nominal mass flow range. Valve design optimisation, based on CFD, to sustain cavitation for a higher downstream-to-upstream pressure ratio is shown.

Opis:
The controversy surrounding the actual impact of institutional quality and economic openness on economic growth is among the motivating factors for this study. The study seeks to investi- gate this relationship in the Economic Community of West African States (ECOWAS) by using the panel autoregressive distributed lag (ARDL) test with annual series covering the period from 2000 to 2020. Findings indicate that in the short-run, regulatory quality and FDI outflows had an adverse impact on the economic performance of the ECOWAS bloc. Furthermore, the long-run results show that trade openness, political stability and FDI outflows had an adverse impact on the economy of the bloc, while regulatory quality positively affected the economy. Consequently, the paper recommends that member countries in the ECOWAS bloc should put in place effective regulatory framework in the short and medium term to attract FDI inflows, while building a strong and stable political environment in the long term.

The main research issue refers to the identification and analysis of the key features and trends revealed on the global maritime container transport market in the years 2020-2022, as well as its general assessment in terms of the effects that such a highly concentrated market's supply side can cause for shippers and container shipping operators. The research is aimed at determining the main premises and factors stimulating the consolidation processes of the container shipping operators and ongoing market vertical and horizontal integration, as well as assessing the risks and effects resulting from maintaining the current system of regulation of this oligopolistic market. While conducting this research, the following methods were applied: factor analysis (FA), market analysis (MA) based on statistical data concerning the supply side, as well as desk research (DR), i.e. in-depth analysis of many reports, opinions, bulletins and data issued by international maritime organisations as well as research institutes. The obtained research results indicate that:1. the very advanced consolidation processes among the leading container shipping operators and, consequently, further integration of the container market, radically changes the balance of power in favour of shipping operators and creates the potential to generate serious disruptions in this market and other links in the global supply chains, 2/ regulatory antitrust authorities need to take appropriate regulatory action to limit their market power via legal measures regarding competition.

The current study aimed to explore the effect of regulatory Focus – Promotion vs. Prevention – in problem-solving among undergraduate students at The Hashemite University. The hypotheses were that promotion focus students outperform prevention focus students in ill-structured problems but underperform them in well-structured problems, and prevention focus students outperform promotion focus students in well-structured problems but underperform them in ill-structured problems. The participants (n=170) were allocated into four groups according to their mindsets and the problems assigned to them (promotion with ill-structured problems, promotion with well-structured problems, prevention with ill-structured problems, prevention with well-structured problems). After the groups solved all the assigned problems, their work was scored according to Measuring Problem Solving Instrument MPSI. The findings confirmed the hypothesis that the regulatory focus affects how problems are solved.

Opis:
In this paper we posed a question about the role of the state with regard to imposing regulations on the sharing economy sectors. Analysis of the institutional frames of the regulatory intervention of the state in the sharing economy still constitutes an underexploited niche. We drew on the literature in institutional economics and other related fields to provide a picture of a reasonable regulation of markets introduced by a state. The paper covers the spheres of information asymmetry, imperfect competition, negative externalities, and the supply of public goods. What may be generally concluded is that there are no sufficient arguments for treating sharing economy entities more favorably as compared to other organizations. As regards the imperfect competition and negative externalities, sharing economy entities may play a key role and should not be excused from respecting general legal rules. Otherwise, some market actors would use the sharing economy cover just to take advantage of the exemptions. The sharing economy may be also an attractive channel of activity from the perspective of policymakers for mixing direct governmental support with other (social) sources for public goods.

Opis:
Nielegalny rynek napojów spirytusowych to bardzo złożone zjawisko społeczne odpowiedzialne za problemy zdrowotne, straty finansów publicznych, korupcję i inne nielegalne działania. Wiedza na jego temat jest tyleż ważna, co trudno osiągalna. Dotychczasowe szacunki dotyczące skali nieoficjalnego spożycia alkoholu znacznie się różniły. Badania Komisji Europejskiej, Światowej Organizacji Zdrowia i instytucji zdrowia wskazały Polskę jako lidera nierejestrowanego spożycia alkoholu w Unii Europejskiej. Z drugiej strony polskie organy podatkowe i Najwyższa Izba Kontroli szacują nierejestrowaną konsumpcję spirytusu na znacznie niższym poziomie. Celem niniejszego artykułu jest przedstawienie metod badawczych pomocnych w oszacowaniu rozmiarów tego zjawiska. Uporządkowanie metodologii jest potrzebne, by zmniejszyć rozbieżności w dotychczasowych szacunkach nierejestrowanej konsumpcji alkoholu w Polsce. Stosowanie wiarygodnych metod, które przynajmniej umożliwiają określenie dynamiki zmian nielegalnego rynku napojów spirytusowych, pozwoli na prowadzenie okresowej oceny skutków regulacji. Dzięki temu możliwe będzie postulowanie zmian przepisów zniechęcających do naruszania prawa.
Illicit spirit drink market is a very complex social phenomenon. The existing estimates of the scale of the unofficial alcohol consumption differ a lot. The European Commission, the World Health Organization and health institution researches indicated Poland as the leader of unregistered alcohol consumption in the European Union. On the other hand, Polish tax authorities and the Supreme Chamber of Control estimate unregistered spirits consumption on a much lower level. The aim of the paper is to present various research methods that can help estimate the scale of this phenomenon. Standardized methodologies are necessary conditions to reduce the disproportions in the previous estimation of unregistered alcohol consumption in Poland. The need of new quality approach is justified due to the fact that illicit spirits market causes individual and social health problems, public finance losses and contributes to corruption and other illegal activities. Comprehensive and reliable tools and scientific approach which at least allow to verify the dynamics of changes in the illegal spirit drinks market, will allow to perform periodic regulatory impact assessments. Thanks to this, it will be possible to recommend changes to the provisions that may discourage violations of the law.
