The Polish – Polish war on the territory of IsraelThe text deconstructs a documentary film Betar by Robert Kaczmarek and Piotr Gontarczyk. The author carries out the analysis adopting two approaches. Firstly, she confronts the factographic side of the film against other sources reporting the events presented in the film. The author also proves that although it has pretensions to being a historiographic work, Betar is, in fact, constructed on the founding myths of the Israeli Zionism. Secondly, she analyses the film as the authors’ viewpoint on Polish fascism and Polish anti-Semitism concealed under the guise of objectifying narrative of a documentary. Seen from such a perspective, Betar perfectly fits into the Polish historical politics. Discussing the issue of Jews in Poland in the pre-war and war times, the film disregards the context of dominance and abuse, that is the majority-minority context; and what is more, it neutralises the Polish anti-Semitism presenting it as equal to the right-wing Zionism as well as an answer to Jewish nationalism.

AbstractOver the past millennium, by the lSth century the Poland nobles democracy had gradual! y dech"ned into anarchy. The culture of Poland is close! y connected with its intricate 1000 year dynamic hts"tory. Poland was known for being the centre of "wall and board " art, including poster. The artist of Poland always been hospitable and eager to follow cultural and artistic trends in other countries. In 2Oth centuries the Poll`ish poster artist focus on cultural advancement, often took precedence over poh"tical and economic activity. These factors have contributed to the versatile nature of Pollish poster with all its complex nuances. AbstrakMelewati era millennium, pada abad ke 18, kehidupan de- mokrasi di Polandia mengalami perubahan besar dari kemapanan ke arah tindakan anarkis. Secara umum, kebudaya-an Polandia berkait erat dengan sejarah kehidupannya yang dinamis selama kurang lebih 1000 tahun. Dibelahan Eropa Timur, Polandia juga dikenal juga sebagai negeri "Seni dinding dan papan pengumuman". Seniman- seniman Polandia sangat terbuka dan berhasrat besar untuk mengikuti perkembangan budaya dan kecenderungan artistik di negara-negara lain. Memasuki abad ke-20, para seniman poster Polandia memilih fokus pada pengembangan kebudayaan setempat, terkadang terlibat pada aktifitas politik

This paper examines the long‑term dependence between the Polish and German stock markets in terms of industry beta risk estimates according to the Capital Asset Pricing Model (CAPM). The main objective of this research is to compare the Polish and German beta parameters of five Polish and three German sector indices using the Bayesian methodology in the period 2001–2020. The study has two detailed aims. First, to develop a modified, Bayesian approach (SBETA model) that generates significantly more precise beta than the traditional model. Second, to compare the results of different time‑varying industry betas in the Polish and German economies, giving a simple investment recommendation, i.e., which sector could be classified as aggressive or defensive. The betas were time‑varying in both markets but less persistent in the German industries, which seems characteristic of an advanced economy. The Banking sector betas were the highest in both markets, implying the aggressive nature of that industry in the last twenty years. For the Polish market industry, the betas of Construction, IT, Food and Drinks, and Telecom were classified as defensive. For the German economy, the Technologies (IT) sector was also classified as aggressive, but Telecom was defensive. The results give a valuable insight into the systematic risk levels in Poland and Germany, reflecting the investors' learning process and indicating that Polish Banking and German technologies outperformed the market in the last twenty years.

The objective of this work was to determine whether Beet virus Q (BVQ), a member of the genus Pomovirus, is present in Poland. BVQ, like Beet necrotic yellow vein virus (BNYVV), is transmitted by Polymyxa betae Keskin. Earlier, BVQ was described as the Wierthe serotype of Beet soilborne virus (BSBV). Now, on the basis of its genomic properties (2), BVQ is recognized as a distinct virus species. BVQ is often found in fields where BSBV and BNYVV are present (4). During the fall of 2005, five plants of a cultivar susceptible to rhizomania (cv. Alyssa) and five resistant to rhizomania (cv. Henrietta) were collected from a field in the Wielkopolska Region of Poland, where BSBV and BNYVV had been previously identified, and tested for BVQ (1). All samples were analyzed by a double antibody sandwich-enzyme linked immunosorbent assay (DAS-ELISA) with antiserum against BNYVV (Bio-Rad, Hercules, CA). Rhizomania was identified only in sugar beet samples of the susceptible variety. The same samples were then tested using a triple antibody sandwich (TAS)-ELISA with commercial antisera against BSBV/BVQ (As-0576.2) and BSBV (As-0576.1) (DSMZ, Braunschweig, Germany). Nine sugar beet plants gave positive reactions with antiserum against BSBV/BVQ and negative reactions with antiserum specific to BSBV. Total RNA extracted from roots of 10 beet samples was then tested using a multiplex reverse transcription-polymerase chain reaction (mRT-PCR) and specific primers designed to amplify a fragment of the RNA2 for BNYVV and BVQ (3). The primers specifically amplified fragments of 545 bp and 291 bp of the BNYVV and BVQ, respectively. BNYVV was detected in all five samples from susceptible sugar beet plants. The presence of BVQ was confirmed in nine of the sugar beer plants, and the RT-PCR products were sequenced. Sequence analysis of the 206-nt amplicon sequence of the Polish isolate of BVQ (GenBank Accession No. DQ309444) indicated 97% nucleotide and 94% amino acid sequence identity with the previously published sequence of BVQ (GenBank Accession No. AJ223596) (2). To my knowledge, this is the first report of the natural occurrence of BVQ on sugar beet in Poland. In Europe, it has been previously reported in Belgium, Bulgaria, France, Germany, Hungary, Italy, the Netherlands, Spain, and Sweden (3,4). References: (1) N. Borodynko et al.

Data mining merupakan proses analisa kumpulan data untuk memperoleh pengetahuan yang berguna. Pengaplikasian data mining sudah menjadi sesuatu yang umum di masyarakat terutama untuk menunjang aktivitas bisnis dan relasi. Bagi perusahaan yang bergerak di bidang bisnis dan perdagangan seperti apotek, data cenderung banyak setiap harinya. Jumlah data transaksi penjualan yang semakin besar tersebut jika tidak dimanfaatkan sebaik mungkin maka hanya menjadi data yang tersimpan di gudang data saja sehingga menjadi tidak efektif. Oleh karena itu diperlukan sebuah aplikasi yang dapat mengolah kumpulan data dalam jumlah besar agar dapat memberikan pengetahuan yang berguna bagi pengguna. Aplikasi Data Mining dengan menggunakan algoritma apriori mempermudah dalam manajemen pengolahan data sekaligus digunakan untuk menganalisis kumpulan data transaksi yang terdapat dalam database. Sistem dapat mengolah data perhitungan analisa pada bulan dan tahun tertentu kemudian menampilkan hasil analisis berupa pola penjualan obat. Hasil analisis diperoleh setelah sebelumnya kumpulan data tersebut diolah oleh sistem berdasarkan tingkat kepercayaan tertentu. Tingkat kepercayaan ditentukan melalui minimum support dan minimum confidence, sehingga dapat diketahui tingkat keterkaitan produk yang telah terjual yang dapat membantu pengguna dalam mengambil keputusan.

Polar bears spend the majority of their lives on the sea ice, where they gain access to seals and mates. In western Hudson Bay, the sea ice melts for three to four months in the summer, and polar bears there are forced onto land. These bears live on their fat reserves for the duration of the iceless period, until temperatures get colder in the fall and freeze up begins. The aggregation of polar bears near Churchill, Manitoba during the ice free period has led to a thriving tourist industry, with a large influx of tourists visiting Churchill in the fall in a six to eight week period, yet little is known about the impacts of this industry on the biology of the bears. This study investigated the effect of tourist vehicles and human presence on the behavior of polar bears over the fall of 2003 and 2004. Overall time budgets were estimated for bears, and the behavior of males and females was compared. Females spent significantly less time lying and more time in locomotion than males. Time budgets were also estimated for bears in the presence and absence of tourist vehicles. Bears spent less time lying and more time in a sit/stand position in the presence of vehicles. Air temperature had no significant effect on the time budgets of polar bears. Tundra vehicle approaches were manipulated to determine effects on polar bear behavior, and to investigate any variables that significantly affected response, including habituation. A response was defined as any sudden whole body movement or change in position or behavior at the time of approach. A total of 25% of all bears responded to the experimental vehicle approach. For bears that responded to approach, the average distance at response was 43 m. The average speed of the vehicle was 0.66 ± 0.02 m/s (range 0.23 to 1.15 m/s). Approach variables that significantly influenced the likelihood of response of a bear to an approaching vehicle included angle of approach and vehicle speed. Direct approaches, in which the bear was in the path of the moving vehicle, had a higher probability of eliciting a response than indirect approaches, in which the vehicle stayed to one side of the bear at all times. Higher speeds of the vehicle increased the probability of a response by a bear. Behaviors of the bear that significantly predicted a response were shifting of the body and smacking of the lips. A playback study was conducted to determine the effects of human induced sound on polar bears. There was no significant effect of human sound on polar bears. Results presented here provide the first experimental evidence of variables in the tourist industry that affect polar bear behavior, and the first evidence of behavioral cues predicting a response to vehicle approach.

The purpose of this thesis research was to examine the dynamic relationship between climate change and tourism, with a direct focus on Churchill, Manitoba’s polar bear viewing industry. This unique tourism industry and the polar bears it depends on, are experiencing the negative effects of climate change due to warmer temperatures and melting sea ice, which significantly impacts the health, appearance, and prevalence of polar bears on display for tourists. Not only is this tourism industry affected by climate change, it also contributes to the ongoing changes of climatic conditions. This is due to the dependence of fossil fuel energy used for transportation, accommodation, and activities which directly contributes to the release of greenhouse gas emissions and thus to global climate change. Emissions from tourism has increased by 3% over the last 10 years, largely as a result of the accessibility and affordability of air travel, the most energy intensive form of transportation (Lenzen et al., 2018; UNWTO-UNEP-WMO, 2008). It has been suggested that in response to the increase in the demand to travel, the tourism industry should take a leadership role to reduce their total greenhouse gas emissions in an effort to decrease the impact of climate change. In this study, a visitor survey was conducted during four weeks of Churchill’s 2018 polar bear viewing season (October 16 to November 16). The aim of the survey was to: 1) estimate greenhouse gas emissions from polar bear viewing tourists and the polar bear viewing industry; 2) identify tourists’ awareness of the impacts of climate change (to and from tourism activities); 3) understand tourist’s climate-related travel motivations, and 4) identify tourists’ opinions on climate change mitigation strategies. Visitor surveys were hand- distributed at the Churchill Northern Studies Centre and at the Churchill Airport to tourists who had participated on a polar bear viewing tour. Surveys were analyzed and compared with the results from similar studies (Dawson et al., 2010 and Groulx, 2015) to identify the changing trends in greenhouse gas emissions, travel motivations, tourists’ knowledge of climate change, and acceptance of climate change mitigation strategies. Similar to trends observed 10 years ago, emissions from polar bear viewing tourists are 3-34 times higher than the average global tourist experience. Tourists’ awareness about climate change has stayed relatively consistent, despite the topic of climate change having received increased attention globally. Tourists recognize that climate change is happening and that it is human induced however, there is still a lack of understanding of how air travel is a contributor to climatic change. Although briefly mentioned in some participant’s responses, the main motivation was not to see a polar bear before it disappeared from the wild. The majority of tourists identified they were traveling to Churchill simply for the opportunity to see a polar bear. Additional motivators were photography, the Northern Lights, and for the opportunity to see other Arctic animals. The climate change mitigation strategies that tourists believed to be the most effective to reduce emissions were educational programs and transportation alternatives (such as taking the train- which was not an option at the time of study due to a rail line shutdown). This research contributes to the existing knowledge about tourism and climate change and provides a current analysis of Churchill’s polar bear viewing industry, enabling a comparison between findings from another study conducted over ten years ago. This research also makes conclusions about climate change mitigation strategies that might be effective for Churchill’s tourism industry to reduce their impact on the environment.

One of the main attractions for tourists visiting Svalbard, Norway, are polar bears. The polar bear is a vulnerable species, dependent on sea ice to survive as this is where they hunt, wander and raise their cubs. Ship-based tourism poses a number of threats mainly due to the disturbances caused by the presence of ships, damage of critical habitats and the increasing interactions and deadly conflicts between humans and polar bears. Appropriate and effective legislation based on scientific knowledge of the impacts of ship-based tourism on polar bears is necessary to ensure sustainable tourism and environmental protection. Species protection and habitat conservation is not an issue isolated to Svalbard or the polar bears but rather just one part of the pressing global issue concerning loss of biodiversity, which is one of the greatest threats to humankind. The Convention on the Conservation of European Wildlife and Natural Habitats (Bern Convention) aims to ensure the conservation of wild flora and fauna species and their habitats. At the time of signing, the Norwegian Government excluded Svalbard from the application of the Bern Convention, ensuring that national conservation policies for Svalbard would be promoted. The Svalbard Environmental Protection Act is the main act regulating environmental protection on Svalbard, including both general principles and specific provisions regarding species and habitat protection. This paper explores the various needs of the polar bear population in Svalbard and the impacts caused by ship-based tourism. The Bern Convention’s provisions relating to the identified threats posed by ship-based tourism are examined and compared with the corresponding provisions in the Svalbard Environmental Protection Act. Moreover, this paper analyses the potential benefits that could arise from the application of the Bern Convention to the Svalbard territory. This paper concludes that the protection of the polar bears could, de jure, be strengthened by the Bern Convention, mainly due to the extensive interpretation of the types of activities that should be prohibited by signatory states. However, the Bern Convention can only be enforced by non-binding mechanisms and it is therefore unlikely that the application of the convention would lead to stronger protection of the polar bears than that which is provided by national legislation. The protection of the polar bear from threats caused by ship-based tourism would therefore, de facto, most likely not be strengthened by the application of the Bern Convention.

Resumo:

Loss of sea ice due to global warming may affect the phenology and distribution of polar bear (Ursus maritimus) denning by altering access to denning habitats. We examined trends in the selection of maternal denning substrate (land versus sea-ice denning) in the southern Beaufort Sea (SB), addressing the potential influence of summer land-use and fall sea-ice conditions on substrate selection. We developed an algorithm based on statistical process control methods to remotely identify denning bears and estimate denning phenology from temperature sensor data collected on collars deployed 1985–2013 in the SB and Chukchi Sea (CS). We evaluated cub survival relative to den entrance, emergence, and duration, and examined differences in the phenology of land and sea-ice dens. Land denning in the SB was more common during years when ice retreated farther from the coast and off of the continental shelf in September. All SB bears that occupied land prior to denning subsequently denned on land; however, only 29% of denning bears that summered on sea ice denned on land. Den entrance and duration in the SB and CS were similar, although CS bears emerged later. Land dens were occupied longer than those on ice. Bears later observed with cubs remained in dens 23 days longer and emerged from denning 17 days later on average than bears that denned but were subsequently observed without cubs, suggesting that den exit dates are related to cub survival. The increase in land-based denning in the SB when sea ice retreated farther from shore, along with the positive correlation between fall land-use and land denning, suggest that further sea-ice declines may result in continued increases of onshore denning. Growing numbers of denning females along the coast may increase the potential for human-bear interactions.

Human-bear interactions are an important consideration of bear biology, as interactions can lead to destruction of property as well as injury or death for both human and bear. Successful analysis of why these interactions occur can lead to appropriate preventative measures and mitigation of further conflict. Bryce Canyon National Park (BRCA) is comprised of relatively poor bear habitat, but a black bear population exists on the Paunsaugunt Plateau, on which the park occupies the eastern edge. Park managers expressed interest in learning more about bear movements and, specifically, bear use of anthropogenic features following a number of human-bear incidents located at backcountry campsites within park boundaries. By analyzing data from GPS radio-collared bears, trail cameras, existing literature, park incident reports and in-depth campsite assessments, we were able to show how bears are using both natural and anthropogenic features on the Bryce landscape. Campsites were assessed for bear habitat, displacement and encounter potential in order to establish an overall human-bear conflict potential. AIC model selection and resource selection functions using GPS collar data showed that bears selected for some anthropogenic features (campsites, springs), while actively avoiding others (trails, roads). Trail camera data, existing literature and park incident reports all pointed toward use of trails. We then considered all data sources used in the analysis and compiled rankings of human-bear conflict potential for each of the backcountry campsites within BRCA, and submitted a detailed report of findings, conclusions and recommendations to NPS personnel. Second, we investigated human-bear interactions at polar bear dens sites on Alaska's North Slope. As parturient female polar bears in the Southern Beaufort Sea subpopulation increasingly construct maternal dens on coastal land features rather than sea ice, they become more likely to interact with industry and other human activity. We wanted to understand what levels of human interaction could lead to disturbance of denning polar bears, and what types of responses were being exhibited by bears following those interactions. We subdivided potential disturbance stimuli into groups based on their size, motion and sound and the used AIC model selection techniques and multinomial logistic regression to analyze records of human-bear interactions at den sites ranging from 1975 through the present day. We found significant probabilities of varying levels of bear disturbance response among a number of stimuli and intensities. However, denning bear families were overall more tolerant of human activity near den sites than expected. Den abandonments were rare, and we documented no cases of reproductive failure following a disturbance event. We hope that our results from the analysis can be used to further enhance management of industry when operating in polar bear denning habitat.

Resumo:

Pregnant polar bears (Ursus maritimus) construct maternal dens out of snow in the autumn where they give birth to and raise altricial young. In recent years, there has been a decrease in polar sea ice extent and thickness, which has led to changes in denning behavior. One such change in the southern Beaufort Sea (SBS) is that polar bears are selecting maternal den sites on land, rather than on unstable sea ice. This change, coupled with expanding petroleum exploration along Alaska's North Slope, heightens the likelihood of bear-human interactions at maternal den sites. The purpose of this research was to 1) describe polar bears' post-den emergence behavior, establishing a benchmark for comparison to identify behavioral changes associated with climate change and disturbance, and 2) explore factors influencing the efficacy of a currently used den detection method, forward-looking infrared (FLIR). Maternal den sites were observed along Alaska's North Slope from March to April of 2009 and 2010. The mean length of stay at den sites post-emergence was 11.3 ± 7.5 d. The mean date of den emergence was 14 March; abandonment 26 March. Adult females were generally inactive (58.4% out-of-den time) with standing being the most prevalent activity (49.9%). Cubs were generally active (76.7%), playing more than any other activity (45.3%). Bears spent the majority of their time in the den (97.3% for adult females and 99% for cubs) with short bouts of intermittent activity (× = 7 min 42 s). We documented the death of one member of a triplet polar bear litter at its den site. All three cubs showed low activity levels relative to other cubs observed, and one died within one week of den emergence. Necropsy confirmed that the dead cub had a low body weight and was malnourished. Capture later confirmed that the two surviving cubs were also undersized. Triplet litters are often smaller and suffer higher mortality rates than singletons and twins. This cub was not only a triplet but also born following 2 y of record minimum sea ice extent, both of which may have played a role in this cub's death. Concurrent with the den emergence portion of this work, we conducted a separate study to identify limitations and optimal conditions for locating dens using FLIR. We took handheld FLIR images of three artificial dens under varied conditions. We tested variables hypothesized to influence detectability with linear models using a zero-inflated negative binomial distribution. Solar radiation, wind speed, and den wall thickness reduced the likelihood of detecting dens. The negative effect of wind speed on detectability increased with increasing distance. To maximize the efficacy of hand-held FLIR, den surveys should be conducted when solar radiation is <16 w/m2 (night) and when wind speed is <10 km/h (6 mph). Adherence to these guidelines will maximize the protection FLIR can afford to denning bears.

In this thesis, a critical analysis is proposed of the relationships between Inuit participation, science and policy in wildlife governance in the Nunavut Territory, Canada. This analysis situates the emergence of a participatory regime for the governance of wildlife in Nunavut, explores its performance and examines the relations between the ways in which wildlife governance arrangements are currently represented in policy and how they are played out in practice across the territory. To pursue these objectives, this research draws upon a number of theoretical perspectives and methodological strategies poised at a crossroads between environmental geography, science and technology studies, political ecology and ecological anthropology. It combines participant observation, semi-directed interviews and literature-based searches with approaches to the study of actor-networks, hybrid forums and scientific practices associated with Latour and Callon, as well as with Foucauldian and post-Foucauldian analyses of power, governmentality and subjectivity. This analysis suggests that the overall rationale within which wildlife governance operates in Nunavut remains largely based on a scientific and bureaucratic framework of resource management that poses significant barriers to the meaningful inclusion of Inuit views. In spite of their participation in wildlife governance through a range of institutional arrangements, consultation practices and research initiatives, the Inuit of Nunavut remain critical of the power relations embedded within existing schemes, where significant decision-making authority remains under the control of the territorial (or federal) government, and where asymmetries persist with regard to the capacity of various actors to produce and mediate their claims. In addition, while the use of Inuit knowledge, or Inuit Qaujimajatuqangit, in wildlife governance in Nunavut has produced some collaborative research and management endeavours, it has also crystallised a divide between ‘Inuit’ and ‘scientific’ knowledge, generated unresolved conflicts, fuelled mistrust among wildlife co-management partners and led to an overall limited inclusion of Inuit observations, values and beliefs in decision-making.

AbstractThis paper considers whether we have any moral responsibility to offer supplemental feeding to wild animals who have lost food access due to climate change. It takes as a particular case the situation of some individual polar bears who, over the next decade, are likely to be threatened with abrupt loss of food access due to changes in sea ice, potentially causing starvation. The paper argues that, as is implied by most positions in animal ethics, there are ethical reasons to assist individual polar bears by supplemental feeding. However, there are also good reasons to hesitate, and to consider potential harms both to bears and to other animals, as well the loss of wildness value that may be involved. From some ethical positions, the likely harms involved make euthanasia ethically preferable to supplemental feeding. But on other plausible ethical arguments, these likely harms are not decisive. We need to know more about the possible effects of supplemental feeding of polar bears. So, the paper concludes that when the first bears are threatened by abrupt loss of food access, a trial of supplementary feeding should be considered in consultation with relevant native peoples.

AbstractBuilding on the two rounds of exposure studies with human milk coordinated by the World Health Organization (WHO) in the mid-1980s and 1990s on polychlorinated biphenyls (PCB), polychlorinated dibenzo-p-dioxins (PCDD), and polychlorinated dibenzofurans (PCDF), five expanded studies on persistent organic pollutants (POPs) were performed between 2000 and 2019. After the adoption of the Stockholm Convention on POPs (the Convention) in 2001, WHO and the United Nations Environment Programme (UNEP) collaborated in joint studies starting in 2004. The collaboration aimed at provision of POPs data for human milk as a core matrix under the Global Monitoring Plan (GMP) to assess the effectiveness of the Convention as required under Article 16. Over time, the number of analytes in the studies expanded from the initial 12 POPs targeted by the Convention for elimination or reduction to the 30 POPs covered under the Stockholm Convention and two other POPs proposed for listing as of 2019. Many of these chemicals have numerous congeners, homologous groups, isomeric forms, and transformation products, which significantly extends the number of recommended analytes.In the studies between 2000 and 2019, 82 countries from all five United Nations regions participated, of which 50 countries participated in more than one study. For the human milk samples of the 2016–2019 period, results are available for the full set of 32 POPs of interest for the Convention until 2019: (i) the 26 POPs listed by the start of the study in 2016; (ii) decabromodiphenyl ether [BDE-209] and short-chain chlorinated paraffins [SCCP] as listed in 2017; (3) dicofol and perfluorooctanoic acid [PFOA] as listed in 2019; (4) medium-chain chlorinated paraffins [MCCP] and perfluorohexane sulfonic acid [PFHxS] as proposed for listing. This is a unique characteristic among the core matrices under the GMP.Four key messages can be derived: These studies are an efficient and effective tool with global coverage as key contributor to the GMP. After collection of a large number of individual samples (usually 50) fulfilling protocol criteria, pooled samples are prepared using equal aliquots of individual samples (physical averaging) and are considered to be representative for a country, subregion or subpopulation at the time of the sampling. The analysis of pooled representative human milk samples by dedicated Reference Laboratories meeting rigorous quality criteria contributes to reliability and comparability and reduces uncertainty of the analytical results. Additionally, this concept is very cost-effective. These studies can be used for regional differentiation based on concentrations of individual POPs between and within the five UN Regional Groups (African Group, Asia-Pacific Group, Eastern European Group, Group of Latin American and Caribbean Countries; Western European and Others Group). For some POPs, a wide range of concentrations with up to three orders of magnitude between lower and upper concentrations was found, even for countries in the same UN region. Some countries had levels within the usual range for most POPs, but high concentrations for certain POPs. Findings of concentrations in the upper third of the frequency distribution may motivate targeted follow-up studies rather than if the observed level of a POP is found in the lower third of frequency distribution. However, the concentration of a POP has also to be seen in context of the sampling period and the history and pattern of use of the POPs in each country. Therefore, results are not intended for ranking of individual countries but rather to distinguish broader patterns. These studies can provide an assessment of time trends, as possible sources of variation were minimized by the survey concepts building on two factors (sampling design; analysis of the pooled samples by dedicated Reference Laboratories). The estimation of time trends based on comparison of median or mean concentrations in UN Regional Groups over the five surveys in five equal four-year periods between 2000 and 2019 provides a first orientation. However, the variation of the number of countries participating in a UN Regional Group in a certain period can influence the median or mean concentrations. Thus, it is more prudent to only use results of countries with repeated participation in these studies for drawing conclusions on temporal trends. The reduction rates in countries should be seen in context with the concentration range: A differentiation of high levels and those in the range of the background contamination is meaningful. If high levels are found, sources might be detected which could be eliminated. This can lead to significant decrease rates over the following years. However, if low background levels are reported, no specific sources can be detected. Other factors for exposure, e.g. the contamination of feed and food by air via long-range transport and subsequent bioaccumulation, cannot be influenced locally. However, only very few time points from most individual countries for most POPs of interest are available, which prevents the derivation of statistically significant temporal trends in these cases. Yet, the existing data can indicate decreasing or increasing tendencies in POP concentrations in these countries. Furthermore, pooling of data in regions allows to derive statistically significant time trends in the UN Regional Groups and globally. Global overall time trends using the data from countries with repeated participation were calculated by the Theil–Sen method. Regarding the median levels of the five UN Regional Groups, a decrease per 10 years by 58% was found for DDT, by 84% for beta-HCH, by 57% for HCB, by 32% for PBDE, by 48% for PFOS, by 70% for PCB, and by 48% for PCDD and PCDF (expressed as toxic equivalents). In contrast, the concentrations of chlorinated paraffins (CP) as “emerging POPs” showed increasing tendencies in some UN Regional Groups. On a global level, a statistically significant increase of total CP (total CP content including SCCP [listed in the Convention in 2017] and MCCP [proposed to be listed]) concentrations in human milk of 30% over 10 years was found. The studies can provide the basis for discussion of the relative importance (“ranking”) of the quantitative occurrence of POPs. This, however, requires a differentiation between two subgroups of lipophilic substances ([i] dioxin-like compounds, to be determined in the pg/g [=ng/kg] range, and [ii] non-dioxin-like chlorinated and brominated POPs, to be determined in the ng/g [=μg/kg] range; both groups reported on lipid base) and the more polar perfluorinated alkyl substances (PFAS); reported on product base [as pg/g fresh weight] or on volume base [ng/L]. For this purpose, results for the complete set of the 32 POPs of interest for the 2016–2019 period were considered. By far, the highest concentrations of lipophilic substances were found for DDT (expressed as “DDT complex”: sum of all detected analytes, calculated as DDT; maximum: 7100 ng/g lipid; median: 125 ng/g lipid) and for chlorinated paraffins (total CP content; maximum: 700 total CP/g lipid; median: 116 ng total CP/g lipid). PCB was next in the ranking and had on average an order of magnitude lower concentrations than the average of the total CP concentrations. The high CP concentrations were caused predominantly by MCCP. If the pooled samples from mothers without any known major contamination source nearby showed a high level of CP, some individual samples (e.g. from local population close to emission sources, as a result of exposure to consumer products or from the domestic environment) might even have significantly higher levels. The lactational intake of SCCP and MCCP of the breastfed infant in the microgram scale resulting from the mothers’ dietary and environmental background exposure should therefore motivate targeted follow-up studies and further measures to reduce exposure (including in the case of MCCP, regulatory efforts, e.g. restriction in products). Further, due to observed levels, targeted research should look at the balance among potential adverse effects against positive health aspects for the breastfed infants for three groups of POPs (dioxin-like compounds; non-dioxin-like chlorinated and brominated POPs; PFAS) regarding potentially needed updates of the WHO guidance. As an overall conclusion, the seven rounds of WHO/UNEP human milk exposure studies are the largest global survey on human tissues with a harmonized protocol spanning over the longest time period and carried out in a uniform format. Thus, these rounds are an effective tool to obtain reliable and comparable data sets on this core matrix and a key contributor to the GMP. A comprehensive set of global data covering all POPs targeted by the Stockholm Convention, in all UN Regional Groups, and timelines covering a span of up to three decades allows to evaluate data from various perspectives. A widened three-dimensional view is necessary to discuss results and can be performed using the three pillars for assessments of the comprehensive data set, namely: analytes of interest; regional aspects; time trends. This can identify possible problems for future targeted studies and interventions at the country, regional, or global level. Long-term trends give an indication of the effectiveness of measures to eliminate or reduce specific POPs. The consideration of countries with repeated participation in these studies provides the best possible database for the evaluation of temporal trends. The continuation of these exposure studies is important for securing sufficient data for reliable time trend assessments in the future. Therefore, it is highly recommended to continue this monitoring effort, particularly for POPs that are of public health concern.

This article addresses the problem of preserving the identity and historic cultural landscape in small towns in southern Poland. Nowadays, the unique character of those centers is frequently endangered by uncontrolled development and a drive towards modern architectonic and technological solutions. Inhabitants of these small towns, or centers currently reduced to the role of districts, do not always feel or understand the need for preserving the values of their little homelands, even though they bear evidence of a rich past and cultural potential. This work presents a few selected examples of small towns in southern Poland, some of which were degraded to the rank of districts at the beginning of the 20th century. Their landscape and cultural potential have been presented, and attention was drawn to the issue of protecting the historic heritage which has so far survived in the given area. Finally, the identity of selected towns and the sense of a struggle to maintain it have been addressed.

The polar bear’s ability to survive in the harsh arctic night fascinates scientific and lay audiences alike, giving rise to anecdotal and semi-factual stories on the radiative properties of the bear’s fur which permeate the popular literature, television programs, and textbooks [1–5]. One of the most interesting radiative properties of polar bear fur is that it is invisible in the infrared region. Some theories have attempted to explain this by claiming that the outer temperature of the fur is the same as that of the environment. However, this explanation is unsatisfactory because surface radiation depends on both the surface temperature and the surface radiative properties [6].

Purpose – to reveal prerequisites of technology-enabled banking development in Lithuania, Poland, and Ukraine; to identify if digitalization was a beneficial factor in households deposits-raising during the COVID-19. Research methodology is twofold: analysis of digitalization index based on World Bank data as a premise of tech-nology-enabled banks development; beta-coefficient analysis and descriptive statistics – for digitalization influence assessment. Findings – digitalization index analysis showed that Lithuania has a more generous benefit in terms of digitalization. Poland and Ukraine follow with a slight gap. Traditional banks of analyzed countries are acting towards digitalization but at different paces. There are both digital and neobanks in Lithuania and Poland, while in Ukraine only digital banks. Analysis of Ukrainian banks deposits highlighted the fact that digital banks were in some cases more preferable for households, especially during a pandemic. Research limitations – lack of data: common digitalization indexes could not be calculated for Ukraine; differences in countries’ banking data: content and structuring criteria. Practical implications – the results could be important for policy recommendations to tackle the blind spots of banking digitalization. Originality/Value – suggested digitalization index could be utilized as a universal. Due to DESI limitations, common for EU countries, we were to create our own index and compare results with calculated by European Commission DESI values. While DESI is calculated using some specific survey data, the proposed index is using standardized data of World Bank; the results of digital and traditional banks deposits comparison could be useful for further study.

The purpose of the study is to determine if the macroeconomic factors influence rates of returns from broad index of stocks in Poland. The study investigates stability of relation between macroeconomic and stock market variables in short and long time period. After running time series regressions we check if selected macro variables are still significant in cross-section of stock returns including control variables like price to book value, capitalization and momentum. The study is based on large sample of individual rates of returns and macroeconomic variables describing real sphere of the economy. Mine findings suggest that the short and long term relation is statistically and economically significant although not stable in the both analysed time horizons. Macroeconomic beta parameter (sensitivity to macro variables measure) is not significant in cross-sectional test proving that traditionally accepted variables (in our study only price to book-value and momentum) still better explain the expected re-turns.
