Background: Breast cancer (BC) is the most common cancer among women in developed and developing countries. In Poland during last three decades BC incidence has doubled. Accordingly to the latest epidemiologic data from the National Cancer Registry in Poland, 2015 was another year with BC incidence increase - 18 106 new cases of BC (age standardized rate/100 000 - 90.9). Moreover, BC is the second leading cause of cancer mortality among women in Poland (14.1% of deaths). As we still don't have sufficient knowledge about BC origin, it is crucial to limit well-known risk factors of BC to reduce number of new cases. To achieve this significant public health goal there is a need to identify and understand women's attitudes and measure their knowledge about protective and risk factors in BC, especially among women in the age of 45 years old and older, which is the most prone group. Aim: To analyze women's attitudes and investigate their knowledge about BC risk and protective factors in the age group 45 years old and older in Poland. Methods: Data from 380 women were collected from May to August 2017 in Poland. Women from this cohort were randomly selected from whole country and included healthy women, women with BC and convalescent women after BC and other types of cancer. The basic inclusion criterion was age of the women - at least 45 y.o. at the moment of the study. As a tool for data collection, original questionnaire has been projected and implemented, both in electronic and paper version. Questionnaire has been divided into following sections: BC completed treatment, education about BC and prophylaxis (BC risk factors) and consisted from 26 questions single and multiple choice. Collected data has been preliminarily analyzed by Microsoft Excel (v. 14.0.7173.5000), taking also into account sociodemographic profile of women from the research group. Results: 43% (166) of women had completed higher education, 49% (187) secondary education (eg high school) and 2% (8) basic education. Among women with the highest level of education 40% (67) had BC, 60% (99) didn't. In the group of women with secondary education it was respectively 72% (137) and 26% (50) and in the group with basic education 87.5% (7) and 12.5% (1). 52% (196) of women completed education about BC risk factors prophylaxis in the past (lectures, courses, etc.). In this group 70% (135) of respondents claim that this education improved their level of knowledge. Among this women, 28% (38) claim that alcohol consumption contributes to BC, 37% (50) - hormonal replacement therapy, 47% (63) - overweight and obesity and 64% (87) - gene mutations - BRCA1 and BRCA2. Conclusion: Study results suggest that there is a need to create and implement coordinated actions aiming education about BC risk factors among women 45+, which is the most prone group. As we still don't have all answers about BC origin, efficient health education seems to be the best way to decrease BC incidence. [ABSTRACT FROM AUTHOR]

Methods of identification and quantitative determination of synthetic dyes in gelatine jellies have been described. Extraction and isolation procedures of synthetic food dyes have been developed specifically for gelatine products. The various techniques have been used as follows: paper chromatography, absorption spectrophotometry and polarography. Tartrazine, Cochineal Red and Indigotin in amounts permitted by Polish legislation have been determined.

There is ample evidence that foreigners suffer from discrimination when trying to integrate. Extreme situations, however, can alter the population's attitude towards foreigners. One example of such an extreme situation is the position of Ukrainians in Poland since the start of the Russian invasion of Ukraine in 2022. It drastically changed the composition and share of the foreign-born population in Poland. In this paper, we examined the attitude towards people with Ukrainian-sounding and other foreign-sounding names in Poland, and whether it has changed. We used an experimental approach, within which we contacted amateur football coaches asking to join a trial training session using typical native- and Belarussian-, German-, and Ukrainian-sounding names. Half of the clubs received an additional signal showing support for Ukraine. Furthermore, a limited subset of participants completed post-experiment surveys. The survey gave us an opportunity to understand why the respondents discriminate. The results show that people with foreign-sounding names receive fewer responses. Surprisingly, people with Ukrainian names are the exception. They received more responses than natives. Signaling support for Ukraine had a positive but not statistically significant effect on the response rate. [ABSTRACT FROM AUTHOR]

In 2020 it is estimated that 281 million people were international migrants. Migrants constitute a potentially vulnerable population in terms of facing discrimination, poor living and housing conditions, and insufficient access to healthcare services. Due to the armed conflict in Ukraine in 2022, almost 10 million people crossed the Polish border within a year of the outbreak of the conflict. The objective of this paper is to present the use of primary healthcare services by people migrating from Ukraine to Poland and identify the barriers in access to healthcare by this group of persons. This study used a qualitative research technique in the form of an expert interview using individual in-depth interviews (IDI). The study group consisted of professionally active primary healthcare providers (doctors, nurses, and facility managers) in Poland. Research was carried out in the areas regarding the availability of healthcare, the potential threats and challenges, and possible system solutions. The results showed that the most common cause for doctor's appointments among migrants are respiratory infections, including COVID-19. Many cases were related to back pain, mainly resulting from the physical work of the patients. Additionally, some barriers to access and the provision of healthcare services for patients from Ukraine were identified. The majority (75%) of respondents indicated language as a significant barrier when providing services. Based on the study results, we recommend creating a dedicated website and telephone hotline for this group of persons as well as the use of traditional media to distribute information about access to healthcare services. It is also essential to focus on assistance for older people, since they may experience more difficulties with language and navigating the healthcare system. [ABSTRACT FROM AUTHOR]

This paper discusses the radiation budget and its temporal variability over Poland. The data analysis is based on the MERRA-2 reanalysis for the years 1980–2020. During the last four decades, the enhancement of climate warming has been observed, which coincides with the changes in the radiation budget. Positive and statistically significant trends at the top of the atmosphere (TOA; 0.7 ± 0.2 W/m2/10 year) and on the Earth's surface (1.5 ± 0.2 W/m2/10 year) radiation budget (net downward flux) are mainly a consequence of changes in the amount of aerosol and greenhouse gases (GHG). According to MERRA-2, the AOD during this period decreased by − 0.19 (at 550 nm), which is 87% of the long-term (1980–2021) mean value (0.22). The reduction of AOD is due mainly to the decline of non-absorbing sulfate particles, which leads to a reduction of single-scattering albedo (SSA) by − 0.008 per decade and Angstrom exponent (AE) by − 0.06 per decade (both trends statistically significant). On the other hand, the GHG concentration increased by 4.9%/10 year and 3%/10 year, respectively, for CO2 and CH4. The total column of water vapor increased (1.3%/10 year), while ozone decreased (− 1%/10 year). Despite the fact that cloud cover and cloud optical depth (COD) decreased (− 1.8%/10 year and − 1.0%/10 year), the impact of cloud on temporal variability radiation budget is small. It can be explained by nearly compensated shortwave (SW) cooling and longwave (LW) heating effects. During the analysis period, near-surface air temperature increased by 2.0 °C. The estimated increase in SW net surface radiation (7.9 W/m2) leads to climate warming by 0.8 °C, which is a consequence mainly of the reduction of aerosol (0.4 °C) and cloud cover (0.2 °C). The impact of the change of SW radiation on air temperature is more pronounced during the warm season, while during the cold, air temperature change is controlled mainly by the variability of air mass advection.

In north-western Poland, cultural and historical structures were erected using erratic boulders of Scandinavian origin. These structures have yet to be subjected to detailed analysis with the aim of determining their origin, type of erratic boulders and rock abundance of a given petrographic type. This topic has not been addressed by art historians in previous studies of similar structures. The objective of this paper is to present five illustrative examples of stone structures that are closely related to cultural heritage in north-western Poland. A comprehensive inventory of the stone material is presented, categorised according to petrographic types. This is accompanied by a guide to the erratics. Furthermore, this article addresses the principles of geoethics and the concept of sense of place, with the objective of fostering a sense of pride in cultural heritage among residents and viewers. The objective was to identify the current and potential future geosystem services that erratic boulders can provide at the aforementioned locations. The survey methods were non-intrusive and included a comprehensive analysis of the stone material at eye level. Furthermore, in addition to graphic and photographic archiving, the petrographic type of rock and the type of indicative erratics were identified in carefully designed test fields. The results were subjected to basic statistical calculations. The results obtained represent a new corpus of knowledge that can be employed in the sustainable development of the five regions through the utilisation of a tool such as geotourism. It is anticipated that the implementation of innovative initiatives aimed at fostering geoenvironmental awareness and providing educational benefits, such as disseminating knowledge about the petrography and history of the sites (including the evolution of stone workshops and techniques), the role of historic buildings in strengthening attachment to roots, and their promotion in the media and on the internet, will result in the attraction of a more diverse group of tourists with interests beyond the current tourist and recreational offerings.

Purpose: The purpose of this paper is to define the impact of training and development (T&D) in the Visegrad countries (V4) as impacted by the Covid-19 pandemic, namely, Hungary, Poland, Slovakia and the Czech Republic. These countries have some political, cultural, social and economic similarities and share some common ground in the human resource development (HRD) sectors. Design/methodology/approach: The authors used the HRD theory and the human capital theory to analyse the context, operations and impact of T&D in the V4 countries due to the Covid-19 pandemic. The research was conducted in 400 companies, 100 from each of the four countries using the computer assisted web interviewing technique. The questionnaire was in a six-point Likert scale format and addressed 12 topics related to T&D: policy, expectations, procedures of diagnosis, preparation, implementation, monitoring, trainees, trainers, investment and expenditures, evaluation, results and controlling. Findings: The authors concluded that in the Visegrad countries, Covid-19 raised expectations on T&D. This was followed by increased levels of action in diagnosis, preparation, monitoring and implementation, following pre-existing and adjusted policies. Evaluation and control were complicated. Investment and results and the human side of the T&D (trainees and trainers) were the ones for which there were more uncertainties and perplexities. Research limitations/implications: The study has the limitation of using only a small sample in four countries. For further research, the authors suggest a larger study extended to all the European Union countries, an in-depth analysis of the current data and the kurtosis on Policy of T&D. Practical implications: The results of the research can be used to improve T&D programs after the Covid-19 pandemic. They could also provide information to external trainers to improve and adjust their services according to the opinions of the respondents of the study. The research findings can also serve institutions responsible for policy provision of HRD at a national level by providing possibilities to apply for funding either within national or regional funds like the National Training Fund in Poland or within European Union money at a national level. Originality/value: The study is original because even if the T&D in V4 countries during the Covid-19 pandemic had already been studied separately (e.g. Mikołajczyk, 2021; Vrabcová, Urbancová 2021; Vinichenko et al., 2021), no empirical, cross-national research analysing specifically the T&D in those countries has been carried out so far. The authors use an innovative methodology, addressing 12 topics and the people involved together with the stages in which a T&D policy is divided. That makes it innovative and very relevant.

One lakh eighty five thousand refugees from Ukraine have started working in Poland since the Russian war began. Drawing on Bourdieusian concepts of capitals, misrecognition, habitus, and the field, the paper theorizes the subjective and objective terms of inclusion across intersectional interplay of motherhood, ethnicity, and refugee status. In particular, we explore how intersectional marginalized identities of individuals shape their negotiation power over terms of their labor market inclusion. Using qualitative interview data from 10 Ukrainian working mothers in Poland who became refugees following the Russian war in Ukraine in 2022, we demonstrate that misrecognition leads to uneven relations of power curtailing working refugee mothers' agency to negotiate the terms of their inclusion.

The ice phenomena are an inherent component of rivers in temperate, continental, and polar climate zones. Evident progress in global warming leads to a decrease in snow cover on land and ice phenomena in water bodies, disrupting the stability of the hydrological cycle and aquatic ecosystems. Although common observations indicate the disappearance of ice phenomena in rivers over recent decades, detailed quantitative research is lacking in many regions, especially in the temperate zone. In this paper, ice phenomena were analyzed on the rivers of southern Poland, located in the upland and mountain areas of the country, as no such studies have been conducted so far. The temporal changes in the annual number of days with ice (NDI) phenomena were studied in locations where ice phenomena were observed every year for at least 30 years between 1951 and 2021. Using straightforward but commonly accepted procedures, such as the Mann-Kendall test, statistically significant decreasing trends in the annual NDI were revealed for the majority of gauging stations. The Theil-Sen (TS) slope mean values were -1.66 (ranging from -3.72 to -0.56), -1.41 (from -3.22 to -0.29), and -1.33 (from -2.85 to -0.29) for the datasets representing the periods 1992–2020, 1987–2020, and 1982–2020, respectively. The results for the annual NDI were additionally presented within the context of meteorological characteristics such as annual and winter (Nov-Apr) air temperature, precipitation, and water temperature. Correlation and regression analyses revealed that the main factor triggering the decrease in NDI is the increase in the average winter air temperature. An increase in temperature by 1°C results in a decrease in NDI by up to twenty days. If these negative trends continue, ice phenomena may disappear completely from southern Polish rivers within few decades. [ABSTRACT FROM AUTHOR]

Following the Ukraine humanitarian crisis, which was a result of the war in Ukraine, ordinary citizens stepped up to spontaneously coordinate various humanitarian responses to support affected populations. In this article such individuals who founded or coordinated this form of spontaneous humanitarian aid are referred to as citizen aid actors (CAA). This paper explores the work of citizen aid actors in Poland, a country which received many of the people displaced by the war in Ukraine. The study applies the concept of digital affordances to illustrate and argue that citizen aid actors relied on the features available on digital platforms to attain their goals. It is an outcome of a qualitative research approach where interviews, participant observation, and analysis of relevant online material about the studied citizen aid actors were used as methods of collecting data. The findings indicate that these actors used diverse digital platforms at different stages of the humanitarian aid projects, from establishment, organization and sustenance. While this study demonstrates how specific digital platforms contributed to the accomplishment of the work done by CAAs, it also highlights how problematic it can be when the actors largely rely on digital platforms. As such, potential risks associated with overreliance on digital platforms as a way of implementing projects are factored in. Ensuing concerns include the presence of online trolls, the spreading of fake news, and internet disruptions as potential obstacles for the success of the aid projects. [ABSTRACT FROM AUTHOR]

This paper focuses on individual responses to education in crisis, with the strategies of students contextualised and examined within a wider multi‐crisis reality. Offering a conceptual framework of social solvation, the proposed model explains how failures in the education system at the macro (state) and meso (institutional) levels translate into young people's behaviours at the individual (micro) level. Based on the analysis of 26 in‐depth interviews with young students, we identify and discuss three main micro‐rational strategies that the interviewees relied upon to navigate their learning during the pandemic: (1) casualisation (2) customisation and (3) contempt towards the broader system. We argue that the already weak Polish education system was further impaired by the COVID‐19 crisis. In response to growing social and educational risks, young people forge and employ highly individualised strategies. As micro‐rational social actions essentially bypass the unwieldy education system in a variety of ways, they have vital implications for educational futures. [ABSTRACT FROM AUTHOR]

Aim Background Introduction Methods Results Discussion Implications To describe how nurses and nursing students in Poland and the United States perceive the practice of intercultural care of refugees from Ukraine.Millions of Ukrainian citizens sought safety in other countries when Russia invaded Ukraine in February 2022.Nurses in Poland and the United States are positioned to provide nursing care for refugees from Ukraine yet lack intercultural knowledge, skills, and attitudes to meet refugee needs.This education‐focused qualitative description study was conducted in Spring 2023. Eighteen MSN and BSN students from one university in Poland and one university in the United States completed an international virtual exchange course that concentrated on the health and well‐being of refugees from Ukraine. Students’ reflection papers generated the data for this study. Content analysis was used to systematically structure the data, and themes were inductively derived for an initial understanding of intercultural care for refugees. The COREQ guidelines were followed for reporting study findings.Major themes were troubled communication, overlooked trauma‐informed care, and compromised vaccine status. Language differences, a gap in nursing knowledge, and cultural variations impeded intercultural care.To address intercultural care for refugees from Ukraine, macro‐ and microlevel factors should be considered. Healthcare facilities need certified interpreters or adequate language‐access technology for nurses. Nursing programs might evaluate content on trauma‐informed care and cultural competency to meet the needs of war‐affected refugees. Leaders from Ukrainian refugee communities could partner with nurses to deliver culturally relevant information to increase vaccine uptake.Nurses should advocate for inclusion of the WHO competency standards of care for refugees in healthcare policies with emphasis on communication and evidence‐informed practice. Placing Ukrainian community leaders on health councils could bridge the gap between refugees and mainstream society. [ABSTRACT FROM AUTHOR]

As the processes of market liberalization and globalization increase the confidence of international actors involved in national third sectors, there exists a cosmopolitan tension between 'mobile elites' and 'locked in' nationals. This paper explores the impact of these tensions on the social enterprise ecosystem in the Republic of Poland and the Socialist Republic of Vietnam. Focused on the internationalized mechanisms of support, the relationship between the social enterprise incubators and international stakeholders, and power distance inherent to the global versus local debate, the findings suggest that normative isomorphic pressures are causing a fundamental ecosystem shift. The monopolization of support and terms of reference have led to entrepreneurs detrimentally being treated as 'organizational heroes' risking burnout, the primacy of international voices within the local context, and the transference of nationals from being 'locked in' to national processes to being 'locked out' of national support. The research suggests the cosmopolitan‐led transformation of activists into entrepreneurs needs to be more carefully considered, to ensure that enforced alignment to international system does not alienate them from other sources and means of sustainability.

Polish Tatars are a minority Muslim community who have lived on the Eastern borderlands of Poland for over 600 years, forming an integral part of Poland despite distinct social and religious customs. I argue that food practices among Polish Tatars in the Podlasie region, rather than being merely a symbolic means of expressing difference, actively create community as forces of both exclusion and inclusion. Affective bonds are reinforced through the bringing together of individuals in the space of the kitchen to cook and consume Polish Tatar food during holidays, but fears of assimilation and loss of identity are reinforced by a perceived weakening of these practices among the youth. Food practices in restaurants represent the community as a type of familiar alterity that is both distinct from, and yet a part of, wider Polish society, while simultaneously mosques complicate binary conceptions of food as belonging exclusively to one group. The contested consumption of pork and alcohol connects Polish Tatars to the wider Polish population as "our Muslims," while also creating boundaries with non-Tatar Muslims. In this paper, food is understood as an agentic force that actively crafts group boundaries of belonging through processes of inclusion and exclusion. [ABSTRACT FROM AUTHOR]

The study presented here is an attempt at a comparative analysis of three early modern phenomena in the history of ideas and culture: three ethnogenetic theories about the origins of the Swedish (Gothic) and Polish (Sarmatian) nations and states, as well as that of the Danes, originating from the ancient Cimbri. First, they will be compared as historiographic concepts characteristic of early modern knowledge. The next part of the paper concerns modifications to these theories made in national historiographies and the broader visions of the history of the respective countries based on them. The last part of the study presents how these ideas function at the political level, both in relation to broader visions of political reality and political practice. The analysis suggests that while in the case of the 16th-century historical concepts of origo gentis, there are more similarities than differences, the subsequent stages of development show increasing differentiation: the ideas of Sarmatian ethnogenesis underwent greater changes than others. However, there are similarities in the way Gothic and Sarmatian ideas functioned in political life and politics during that period in Sweden and Poland, respectively. The weakest point is the influence of Cimbrian ethnogenesis on the politics of Denmark at that time. [ABSTRACT FROM AUTHOR]

The paper offers an analysis of future prospects of poor working persons. It pays attention to transitions from in-work poverty, focusing, in particular, on the probability of remaining at work and move above the poverty line. The analysis brings new insights into the situation in the countries in Central Europe, expanding limited knowledge on this subject. It shows that they differ in several aspects of in-work poverty and its dynamics, including the mobility of working poor as well as presence of their various trajectories. For example, while Poland stands out as the country offering most limited chances for "positive" mobility from working poverty, Hungary represents the most "open" regime, where working poor's future prospects seem to be more favorable. Findings from the empirical analysis covers the period 2012–2019, based on the pooled longitudinal dataset from the European Survey on Income and Living Conditions (EU SILC). [ABSTRACT FROM AUTHOR]

Aim. The aim of the study was to review the existing research, conducted on animal and human models, regarding the possibility of using low doses of naltrexone (LDN) in treatment of non-suicidal self-injury (NSSI). Method. The available Polish- and English-language literature on NSSI was reviewed. Relevant studies were identified through an electronic search of PubMed/MEDLINE and Google Scholar databases using the following keywords: non-suicidal self-injury, NSSI, naltrexone, LDN, self-injury, self-harm, and time descriptors 1982-2022. The review was based on information reported in original papers, review articles and case reports. The quality of the article was assessed using the six-point Scale for the Assessment of Narrative Review Articles (SANRA). Results. Studies conducted on animal models show that use of LDN can prevent habitual self-injury. As far as the possibility of clinical use of LDN in treatment of NSSI is concerned, results of a relatively small number of studies conducted so far confirm the efficacy of using naltrexone 25-50 mg/day to decrease or eliminate self-injurious behaviors in NSSI patients. Conclusions. The use of LDN in treatment of NSSI seems to be a promising clinical option, whose efficacy, however, needs to be corroborated in a larger number of randomized placebo-controlled clinical trials.

Although the first numerical dating of Middle and Upper Palaeolithic sites in Poland was applied at the beginning of the second half of the 20th century, it has only been in the last two decades that a data increase has been recorded, making it possible to discuss both the development of human behaviour and cultural phenomena in time perspective. This paper aims to show the chronological diversity of sites dating from the beginning of the Weichselian glaciation (MIS 5a - MIS 5d, GI-19 - GI-23, Greenland Interstadials) to the middle part of MIS 3 (GI-8 - GI-10). We considered sites dated mainly by thermoluminescence dating (OSL) and radiocarbon dating. We relied on a series of recent datings. We attempted to analyse the stratigraphic integrity, the archaeological finds and the numerical dating results. Through OSL dating, we could establish the chronology of Micoquian sites, previously regarded as middle Pleistocene, to the last glaciation. The dating compilation also shows that the Late Middle Palaeolithic and Early Upper Palaeolithic (EUP) sites are unlikely to overlap, or if they do, it is only over a small period. Unfortunately, this period is poorly interpreted because it spans the limit of the radiocarbon dating reliability and goes beyond the bounds of the calibration curve. Confronting the datings of the Lincombian-Ranisian-Jerzmanowician (LRJ) complex and the oldest finds associated with Aurigniacian sites in Poland lead to the conclusion that these sites may have co-occurred for some time.

The paper addresses the problem of weighting in an analysis that supports the selection of a categorical data set according to user needs. Using the Relative Change (RC) of the Compound Correspondence Index (CCI), it is shown that weights have a significant impact on user choice - reaching extreme values in both urbanized and forested areas. Decreasing the weights from 0.25 to 0.17 in forested and built-up areas resulted in the maximum variations that were seen in the hot spot maps, with cold areas generally corresponding to builtup regions and hot areas to forested areas. The analysis covers seven counties that are located in different regions of Poland: Pomerania, Podlasie, Mazovia, Greater Poland and the Beskidy Mountains. [ABSTRACT FROM AUTHOR]

The occurrence of disparities in income among various social groups is defined by the economic term social inequalities. In the subject literature, this term is often used in association with the individuals with disabilities and their uncertain position in the job market or the barriers that they face in the education process. Thus, this paper attempts to fill an existing research gap by answering the research question of how the employment level will change among individuals with disabilities with a specific level of education if the number of individuals with disabilities with higher education changes. The main goal of the conducted study is to analyse the impact of the population size of individuals with disabilities of working age on their employment level in Poland, taking into account differences in the level of education. Particularly, the focus is on the relationships between the level of education and earning potential. To obtain answers to the research question, a national and international literature analysis was conducted, and in the empirical part, a panel regression model was employed. The results of the panel regression analysis indicate a significant impact of the interaction between the population of individuals with disabilities and the level of education on employment in Poland. Education plays a significant role in the employment outcomes of individuals with disabilities, and this dependency is also influenced by the demographic factor of population size. The interpretation of indicators may indicate a significantly higher demand for vocational and technical skills in the labour market, compared to contributing to higher employment rates of individuals with disabilities possessing these specific qualifications.

This paper presents excerpts from the activities undertaken by archaeologists associated with Upper Silesia, carried out at the Silesian Scientific Institute in Katowice. This institution existed for 35 years (1957-1992), during which time two archaeological commissions operated within its structures. The first was active between 1957 and 1972, the other between 1984 and 1988. This text provides an overview of the conditions surrounding the creation of both bodies, primarily based on the surviving archival material from the Silesian Scientific Institute. It focuses on the scientific activities of researchers studying past cultures and civilizations conducted under the Institute's auspices, as well as the unique aspects of archaeological research in the Polish People's Republic.

PURPOSE: Due to the detrimental effects of the recent pandemic on the hotel sector, hotel resilience research and its impact on hotel recovery have received lots of academic attention. However, a sustainable perspective on hotel resilience, as an approach for investigating its impact on long-term hotel growth, has been largely overlooked in the hospitality resilience literature. Therefore, this paper aims to address the research gap by identifying the configuration of factors that constitute sustainable hotel resilience, leading to the growth of selected hotels operating in Poland. METHODOLOGY: Data for analysis were obtained from surveys conducted with 120 managers of one- and two-star hotels. A fuzzy-set qualitative comparative analysis (fsQCA) was chosen to achieve the goal, which belongs to the group of configurational analysis methods. FINDINGS: Due to the asymmetric nature of the method, the analysis reveals configurations of factors leading to high hotel growth and those leading to low growth. In both cases, two such factor configurations were obtained. For high levels of hotel growth, it was found that maintaining a high level of three factors simultaneously, namely employee resilience, CSR activities and leadership resilience or CSR activities, team resilience and leadership resilience, provided sufficient conditions. For low levels of growth, fsQCA indicated sufficient conditions in the form of a low level of CSR activities and leadership resilience or a low level of employee resilience and team resilience. These findings emphasize the role of combining different factors to improve hotel growth. IMPLICATIONS: The research contributes to the literature on resilience in the hospitality industry by developing a new theoretical perspective on the complex nature of combinations of factors that contribute to sustainable hotel resilience, leading to both high and low growth. The research results also provide significant implications for entrepreneurs and managers, indicating the role of different combinations of factors in determining hotel growth. ORIGINALITY AND VALUE: The knowledge regarding sustainable hotel resilience is still insufficient. The study identified the best combinations of factors (both internal and external) that constitute sustainable hotel resilience, which may be vital for hotel growth. [ABSTRACT FROM AUTHOR]

This paper investigates the (un)making of borders as a form of labour governmentality in one of Amazon's warehouses in Poland. Guided by a critical theory of borders as a form of labour governmentality under global capitalism, we identify organizational practices through which socio-demographic categories traditionally deployed as principles of organizing work (e.g., gender, age, ability) are un made: the management of deskilled labour through an algorithmic system, the non-selective hiring of workers, the enforcement of social norms of interpersonal respect and a universal system of casualized employment. Together, these practices constitute workers as undifferentiated, interchangeable and equal labour, let them compete with each other under harshly exploitative conditions, and continuously dispose of the least productive among them, keeping all in structural uncertainty. The study contributes to the critical diversity literature by showing a 'post-diversity' governmentality that rests on equality, competition and precarization of labour as a whole, rather than segregation and marginalization through an 'ideal worker' norm. This labour governmentality operates by eliciting consent from historically subordinated workers and eliminating the advantage of historically relatively privileged ones. Unmaking borders within labour inside the organization, this governmentality at the same time crucially rests on borders outside it. [ABSTRACT FROM AUTHOR]

Rockbursts represent one of the most serious and severe natural hazards emerging in underground copper mines within the Legnica–Glogow Copper District (LGCD) in Poland. The contributing factor determining the scale of this event is mining-induced seismicity of the rock strata. Extensive expertise of the copper mining practitioners clearly indicates that high-energy tremors are the consequence of tectonic disturbances or can be attributed to stress/strain behaviour within the burst-prone roof strata. Apparently, seismic activity is a triggering factor; hence, attempts are made by mine operators to mitigate and control that risk. Underlying the effective rockburst control strategy is a reliable seismicity forecast, taking into account the causes of the registered phenomena. The paper summarises the geomechanics analyses aimed to verify the actual seismic and rockburst hazard levels in one of the panels within the copper mine Rudna (LGCD). Two traverses were designated at the face range and comparative analyses were conducted to establish correlations between the locations of epicentres of registered tremors and anomaly zones obtained via analytical modelling of changes in stress/strain behaviours within the rock strata. The main objective of this study was to evaluate the likelihood of activating carbonate/anhydrite layers within the main roof over the excavation being mined, with an aim to verify the potential causes and conditions which might have triggered the registered high-energy events. Special attention is given to two seismic events giving rise to rockbursts in mine workings. Results seem to confirm the adequacy and effectiveness of solutions provided by mechanics of deformable bodies in the context of forecasting the scale and risk of dynamic phenomena and selecting the appropriate mitigation and control measures in copper mines employing the room-and-pillar mining system.

The aim of this paper is to assess the correlation of groundwater level changes (or groundwater level anomalies (GWLA)) obtained from direct measurements in wells with groundwater storage anomalies (GWSA) calculated using Gravity Recovery and Climate Experiment (GRACE) products and Global Land Data Assimilation Systems (GLDAS) models across different climate zones, from temperate Poland to Arctic Sweden. We recognize that such validation studies are needed to increase the understanding of the spatio-temporal limits of remote sensing model applicability, not least in data-scarce sub-Arctic and Arctic environments where processes are complex due to the impacts of snow and (perma) frost. Results for temperate climates in Poland and southern Sweden show that, whereas one of the models (JPL_NOAH_GWSA) failed due to water balance term overestimation, the other model (CSR_CLM_GWSA) produced excellent results of monthly groundwater dynamics when compared with the observations in 387 groundwater wells in the region during 2003–2022 (cross-correlation coefficient of 0.8). However, for the sub-Arctic and Arctic northern Sweden, the model suitable for other regions failed to reproduce typical northern groundwater regimes (of the region's 85 wells), where winter levels decrease due to the blocking effect of ground frost on groundwater recharge. This suggests, more generally, that conventional methods for deriving GWSA and its seasonality ceases to be reliable in the presence of considerably infiltration-blocking ground frost and permafrost (whereas snow storage modules perform well), which hence need further attention in future research. Regarding long-term groundwater level trends, remote sensing results for southern Sweden show increasing levels, in contrast with observed unchanged to decreasing (~10 mm/a) levels, which may not necessarily be due to errors in the remote sensing model but may rather emphasize impacts of anthropogenic pressures, which are higher near the observation wells that are often located in eskers used for water supply. For sub-Arctic and Arctic Sweden, the (relatively uncertain) trend of the remote sensing results nevertheless agrees reasonably well with the groundwater well observations that show increasing groundwater levels of up to ~14 mm/a, which, e.g., is consistent with reported trends of large Siberian river basins.

The natural resources of a country, including ichthyofauna, constitute a vital aspect of its national heritage. Fish populations are threatened with loss of biodiversity as a result of human activity (anthropopressure), resulting in water pollution, habitat destruction and overfishing. Additionally, the escalating threat is exacerbated by climate change, primarily manifested in periodic reservoir and watercourse desiccation. Genetic variability of captive is also threated as fish raised in hatcheries are susceptible to bacterial and viral diseases. Therefore, methodologies for fish sperm cryopreservation aimed at safeguarding the gene pool of both natural and captive fish populations assume paramount importance for their conservation and mitigation of irreversible losses, particularly crucial in light of increasing ecological disasters. This paper offers an overview of cryopreservation research in Poland, tracing back to early initiatives in the 1970s concerning carp (Cyprinus carpio) semen and culminating in recent advancements, where standardized cryopreservation methodologies were developed. We delve into the freezing results of semen of various fish species, encompassing both wild specimens like whitefish (Coregonus lavaretus) and lake minnows (Eupallasella percnurus), and farmed species such as sturgeons, carp, and numerous salmonid species. Additionally, we delineate projects that support such endeavors. Recent milestones in the establishment of fish sperm cryobanks in Poland catering to both wild and farmed species, including carp and rainbow trout (Oncorhynchus mykiss) - the most economically significant fish in Poland were presented. We also expound on the implementation of cryopreserved semen from sex-reversed rainbow trout in hatchery practices. Furthermore, we discuss significant challenges pertaining to sperm banking, particularly concerning funding and the practical utilization of cryostored semen samples for egg fertilization under hatchery conditions.

Purpose: the aim of the article is to provide a broader context for the discussion on the significance and role of cybersecurity system in Poland. Cybersecurity is extremely significant for individual users, enterprises and entire countries. Cyberthreats might lead to serious consequences, for example data theft, loss of reputation, financial losses. They can be even dangerous for national security. Therefore, cybersecurity is an intrinsic element of the security system which needs to be constantly enhanced and adapted to the dynamically changing environment of threats. Design/methodology/approach: the article is cross-sectional. The implementation of the goal is based on a critical analysis of literature. Findings: the cross-sectional approach and literature review employed in this study have contributed to a comprehensive understanding of cybersecurity system in Poland. Practical implications: effective cybersecurity has a fundamental meaning for the stability and national security of Poland. Providing protection against cyberthreats is crucial for maintaining the continuity of essential services, securing data protection and citizens’ privacy, as well as for preventing potential disruptions in the functioning of economy and critical infrastructure. Social implications: an effective cybersecurity system builds public trust and strengthens the position of Poland on the international area as a country capable of protecting its interests in the digital world. In the face of dynamically changing threats, continuous improvement and adaptation of the cybersecurity system remains necessary to tackle contemporary challenges and ensure long-lasting stability and national security. Originality/value: this paper has provided an in-depth exploration of cybersecurity system in Poland the context of management. [ABSTRACT FROM AUTHOR]

Purpose: The article analyses two transformation variants: the Polish variant and the variant used in the People's Republic of China. This analysis was carried out in the context of the cultural background of both nations. The authors also tried to answer the question to what extent the reform programs of both economies, known as the Balcerowicz Plan and the Beijing Consensus, were culturally compatible and whether they impacted their effectiveness this. The article draws attention to the level of social acceptance of the transformation scenario adopted in the country and the role of both decision-making centralism and economic democracy in the conditions of a market economy. Methodology: The review of literature. Findings: As a result of the literature analysis, it was established that the reforms carried out as a result of the Balcerowicz plan took into account the cultural conditions of the Polish economy to a limited extent, which resulted in incomplete and delayed use of the potential of Polish social and intellectual capital. Chinese reforms, on the other hand, were carried out in a way that was more suited to Chinese realities, which, among other factors, enabled China to develop more dynamically without leading its economy to a periodic collapse caused by the transformation processes. Value of the paper: The article is analytical and synthetic in nature and is addressed to a wide audience, primarily to decision-makers managing the economy at various levels and to students of economics and management. The article is not only retrospective in nature, but also encourages deeper reflection on the future and may be helpful to managers in making economic decisions, in which they should take into account the cultural aspect to a greater extent than before.

Extreme precipitation of a minimum daily value of >30 mm often initiates natural hazards such as floods, which in turn may not only lead to property damage but also present a danger to people's health and lives. This paper mainly focuses on examining the trends and frequency of extreme daily precipitation (EDPr) in Poland. Also, it determines natural risk zones caused by EDPr of >30 mm, >50 mm, >70 mm, and >100 mm. In Poland, a significant positive trend was found for EDPr > 30 mm, >50 mm, and >70 mm in September, and for EDPr >100 mm in May. The most frequently recorded EDPr in Poland was >30 mm, the frequency of which ranged from 0.04% in February to nearly 3% in July. EDPr of >100 mm was recorded in 4 months, from May to August. An increase in the frequency of monthly EDPr in Poland occurred mainly in the southwestern and western parts. In Poland, three hazard zones of various frequencies of EDPr events were determined. In Zone III, which is in the southwestern and southern parts of the country, EDPr events occurred far more often than in Zone I; on average, four times more in the spring–summer season and slightly more than five times more in the autumn–winter season. The obtained results may help in the building of modern management and monitoring systems for the prevention of natural hazards caused by extreme precipitation. [ABSTRACT FROM AUTHOR]

Background: One of the potential dimensions on which exclusion and injustice may occur in energy transitions is age. Age-based patterns of exclusion—ageism—has recently been conceptualized in the context of decarbonization as energy ageism. This paper offers a comparative empirical analysis of the senior citizens' outlook towards an imminent energy transition as well as the impact of energy poverty in two European countries: Norway and Poland. Results: Drawing on interviews and focus groups with Polish and Norwegian seniors, we present the differences and similarities between the two countries, and the determinants of energy ageism, as well as the concept's overall applicability and empirical usefulness. We find that socioeconomic conditions outweigh ageism, that is, the resilience of senior citizens in dealing with energy poverty during a transition is conditioned by their material standing and welfare state robustness rather than age based. An important factor is household heating technology, combined with economic vulnerability can push some individuals into energy poverty, while others using alternative sources of heat can navigate through energy crises unscathed. Conclusions: We note the importance of mainstreaming social inclusion considerations in energy policy and of targeted digital competence building which can enhance senior citizen integration in the energy transition. Lower levels of digital competences among senior citizens certainly play a role and need to be addressed with education programs to increase participation. In both countries, household heating is a major issue and heating sources are strong predictors of energy poverty and regulatory measures and subsidies should be designed at national, regional, and municipal level to assist vulnerable groups in this area.

Simple Summary: The digitization of herbarium collections is an important process that allows access to sometimes huge amounts of data that can be used in various natural sciences. In recent years, the collections of one of the thirty oldest herbariums in the world—the herbarium of the Jagiellonian University—have been digitized. This paper presents the resources of the economically very important Amaranthaceae family, which include 8801 herbarium sheets. They were analyzed in taxonomic, geographical, historical, and functional terms. Herbaria constitute a form of documentation, store and secure comparative material, as well as constitute an extra original gene bank. They are an invaluable database among others for the biological, ethnobotanical and agricultural sciences. The digitization of herbarium collections significantly facilitates access to archival materials; however, searching them is still time-consuming. Therefore, our work aims to analyze the herbarium collection of 8801 sheets for specimens representing the economically important family Amaranthaceae (Chenopodiaceae-Amaranthaceae clade) deposited the oldest herbarium in Poland, the herbarium of the Jagiellonian University (KRA). These specimens have been collected from almost all the continents in dozens of countries for over 200 years. The analyses conducted, including the taxonomic coverage, geographical characteristics and origin, temporal coverage and utility importance of representative species, present the discussed resources in a more accessible way and may become a more attractive form for scientists potentially interested in more advanced research work.

Approximately 22% of the existing dwellings in the EU were built before 1946. In Wrocław, Poland ca. 21% of all dwellings in multifamily houses are protected for their heritage value. For such a significant share of the residential building stock pursuit of sustainability through amenity improvement is inevitable and will gain pace with the EU endorsed Renovation Wave. The discourse about the scope of renovations should be extended to consider an improvement of historical housing's spatial quality without compromising its heritage value. Balconies are perceived as an indispensable part of new-built apartments; however, they are scarce in tenements built at the turn of 20th century. Adding balconies as a part of retrofitting is common in Germany or Denmark, but rare in Poland. By analysing heritage preservation practices in Chemnitz, Copenhagen and Wrocław, this paper aims to understand how retention of heritage value shapes local approach to adding balconies. Semi-structured interviews (18) were conducted with heritage conservation officers and other stakeholders. The results revealed a shared recognition of balcony's role as an element contributing to heritage housing preservation through enhanced usability. Factors that impede balcony additions in historical tenements in Wrocław were identified for different tenure types, followed by recommendations. [ABSTRACT FROM AUTHOR]

The development of wind energy has been observed for many years. Both construction firms and the scientific world are analyzing new design solutions, atmospheric conditions and the technical performance achieved. The main goal of this research is to evaluate the requirements that have to be met to design wind power stations that would be an optimal fit for the climatic conditions in Poland. This study combines the results of empirical studies on wind velocity distributions with the physical fundamentals of wind power station design. This paper presents modelling of the relationships between wind velocity distributions observed in Poland and technical requirements for wind power stations design. The wind velocities distributions for various locations in Poland are determined and expressed in Weibull distribution parameters. Theoretical computations concerning the dependence of wind power stations as function of wind speed and air's physical properties are presented. Conclusions important for the design of power stations fitted to the atmospheric conditions in Poland are given. LabVIEW 2021 was used for computer modeling. [ABSTRACT FROM AUTHOR]

This paper discusses the financial determinants of the efforts of local government units (LGUs) to invest in the area of energy transition (ET). The main objective is to verify the links between the scale, directions, and funding sources of LGUs' investments in ET and their budgetary situation described by the level of income independence, budget result, and debt level. The general research hypothesis assumes that the ET investment activity of LGUs is associated with their financial situation. The analysis covers the period 2019–2022 and uses data from the questionnaire-based survey conducted in 2023 among 181 LGUs in the Podkarpackie region in southern Poland. Non-parametric tests were employed to verify the association between the LGUs' ET investment activity and their financial situation: the Chi2 test, the Mann–Whitney U test, the Kruskal–Wallis test, and the Kendall's Tau correlation. Financial aspects were shown to influence the scale of municipal ET investments, as well as the type of projects implemented. Among the analysed financial indicators, the debt level was the most important constraint for LGUs to make their own ET investments. The debt level not only determined the scale of municipal ET investment, but also influenced decisions on the type of investments. [ABSTRACT FROM AUTHOR]

The occurrence of subsurface karst caves can cause the development of superficial depressions which, in turn, may pose a construction hazard. Identifying such a substratum requires integrated non-invasive measurement methods. The main objective of the study was to demonstrate the effectiveness of the non-invasive ERT, TLS, and GPR survey techniques in identifying the karst floor and determining the direction of discontinuities around the cave. The paper analyzes the limitations of the methods used in the study of heterogeneous media. These limitations are related to the methodology and measurement conditions, data processing, and interpretation in the context of the resolution and depth range. The study was conducted using the example of the Jaskinia pod Świecami cave, formed in the Sarmatianal calcarenites in Poland. The research confirmed its complex karst-anthropogenic genesis. The cave was formed as a result of the infiltration of rainwater and the dissolution of limestone by groundwater, while the paleokarst forms that are characteristic of it and of the surrounding caves and occur in their vicinity, i.e., narrow ridges called "karst candles", were formed as a result of water circulation during the local permafrost degradation in the middle Pleistocene. However, these forms were modified in the Upper Pleistocene and Holocene, as indicated by ERT images. [ABSTRACT FROM AUTHOR]

Poland is a case of a state in which the role of legislative bodies in the political system has been gradually reduced at the various levels – national, regional, and local. Recently, this process has been related to executive aggrandisement observed in Poland, but the roots of this phenomenon can be traced back to the political transformation of this country observed after 1989. At the national level, the deteriorating legislative role of parliament manifests itself in four general processes: (1) The executive power treats the Sejm (lower chamber) as a subordinate institution. This involves formally introducing laws forced by the government in the form of proposals written by members of parliament (MPs) (as a way to shorten the legislative process and limit public consultations required by law); (2) Speeding up of parliamentary works – the Sejm is treated as a voting machine and not as a forum where debates and discussion take place; (3) Public consultations are superficial and the regulatory assessment impact is minimal; (4) The influence of the opposition on legislative processes is reduced to almost zero. Similar processes can be observed at the regional and local levels. The subnational legislative bodies are often under the control of executives. Instances of voting with no or limited discussions (favouring the governing majority) can be sometimes observed during the sessions of local and regional councils. This paper analyses the weakening of the legislative function in Poland at different levels, using a qualitative approach and data from desk research, media analysis, in-depth individual interviews and focus group interviews.

Older adult education is still under-researched, with many terminological ambiguities, clichés, and prejudices. Older adult teacher education and older adult English as a foreign language (EFL) teacher education is rare. Many factors can influence EFL teachers of older adults' teaching performance and its perception. Pre-service (presumably inexperienced U3A EFL teachers) and in-service teachers (experienced U3A EFL) were teaching EFL to selected older adults (aged from 64 to 75 years) at the Karkonosze University of Applied Sciences in Jelenia Góra, Poland, U3A. Their teaching Older adult education is still under-researched, with many terminological ambiguities, clichés, and prejudices. Older adult teacher education and older adult English as a foreign language (EFL) teacher education is rare. Many facting performance factors list. By utilizing a critical foreign language geragogy and a strengths-based approach inspired by positive psychology, the research emphasized the role of general teaching experience and/or age-targeted teaching experience. And it led to validating the desirable teaching performance factors as factors that defined U3A EFL teaching performance as successful and positively evaluated by given older adult learners, i.e. on a small scale. Based on a qualitative comparative exploratory study, the paper analyses how to approach teaching EFL to older adult learners at a University of the Third Age(U3A). It aimed to design a desirable U3A EFL teaching performance and to validate it on a small scale. It focused mainly on what role teaching experience and official educational study path play. A comparison is made between pre-service (presumably non-experienced U3A EFL teachers) and in-service teachers' (experienced U3A EFL teachers) teaching performance at one selected U3A EFL course and its attendees (aged 64 to 75 years). The study revealed that positively perceived (and successful) teaching performance needs to involve, among others, the following factors: establishing a friendly atmosphere, adjusting materials to the target group and the tempo, becoming partners with learners, and being sensitive to their limitations and barriers and respectful to their wishes and needs. However, within researched countries, pre-service teachers are not being prepared to teach older adults in their formal education path. The teachers' experience plays high role in the ability to adapt and adjust, however the foreign language enjoyment perceived by older adults is universal. It was perceived at both variants, i.e. at pre- as well as in-service teachers' teaching performance. [ABSTRACT FROM AUTHOR]

The literature on cross-border cooperation in Europe is predominated by the analysis of the European Union (EU) INTERREG Programmes' results, while other support funds are often neglected. To fill this research gap, the authors undertook the research on cross-border cooperation of the area-based partnerships (Local Action Groups – LAGs) from Poland and the Czech Republic, financed by the Rural Development Programmes (RDPs) 2014–2020. The main purpose of our paper is to identify the rationales for cooperation, strategies to find partners, the scope of activities and obstacles in implementing the joint projects. The qualitative research involved a content analysis of LAG documents and interviews with LAG managers. The actions in twelve identified cooperation projects were mainly related to local traditions, inventory and the promotion of local products and services, the development of tourism and environmental issues. The respondents have emphasised that these actions required separate financing by national RDPs following different administrative rules, even though when constituting the components of a single project. The bureaucratic restrictions resulted in a clear asymmetry of LAGs activities, manifested in a lower involvement of the Czech LAGs. As a result, many projects can be considered as highly unilateral, solely national rather than genuinely international, which has not been the intention of the LAG managers, however.

This paper proposes a multidimensional approach to collective violence. Stemming from the literature on collective violence and intergroup relations, a sociostructural model is proposed, functionally connecting the structure of intergroup relations with the variety of collective violence. Three archival databases on anti‐Jewish pogroms in Poland and the Russian Empire at the turn of the 19th and 20th centuries are used to demonstrate the variability of types of pogrom violence and its relations with social structure. The results are discussed in light of various intergroup threat theories. [ABSTRACT FROM AUTHOR]

From the beginning of the 21st century, the heat waves in Europe have become more frequent, severe and longer lasting, especially in the southern region. The longer duration of heat waves may be partly attributed to wave‐amplification, high‐amplitude waves in the mid‐latitudes, favouring the longer‐lasting blocking systems. The primary objective of the paper was to examine the long‐term changes of hot days and heat wave events and to identify the atmospheric circulation condition that prevails its occurrence. The other object was to investigate the correlations between hot days' occurrence in Poland and sea‐ice cover and sea surface temperature changes in the Arctic and its surroundings. Over the past few decades, Central and Southern Poland have experienced a considerable rise in maximum temperatures, which has led to an increase in the number of hot days. This increase is particularly prominent during the summer months (June, July and August) but also in May and September, which extends the hot season. Although heat waves have become more frequent and persistent since 2006, their mean intensity has remained unchanged. During all heat waves in Poland, the high‐pressure centre was located over the country or its close neighbourhood, mainly in the eastern sector but also in the south, southwest or over Scandinavia. The blocking systems were mainly related to the extended ridge of the Azores High, but also to strong blocking over the North Pole and Greenland reaching Scandinavia or anomalous high pressure in the East Arctic. The longest‐lasting heat waves were usually preceded by air masses advection from the Atlantic, but the highest potential temperature along the trajectories was observed for the southern direction of inflow. The growing number of hot days is statistically significantly related to the decreasing sea‐ice cover and increasing sea surface temperature in Arctic and Subarctic regions. [ABSTRACT FROM AUTHOR]
