ABSTRACTWith the growing expansion of urban areas and their associated “domes” of artificial illumination, amateur astronomers have been forced to change many of their observing habits. This is reflected in the instruments today’s amateurs are using: highly portable telescopes of mostly commercial origin. Amateurs must travel further into the field to find dark skies, and this makes the hobby more discouraging. By discouraging the amateurs, an important education resource is lost to the public.

AbstractBackgroundPersons with rare disorders, such as tetralogy of Fallot, often feel socially isolated due to poor public awareness of the disorder. On 1 May 2017, Jimmy Kimmel aired a segment on Jimmy Kimmel Live! highlighting the impact of tetralogy of Fallot on his son and how the public can learn more about the disorder.MethodsWe tracked public interest in tetralogy of Fallot using Google Trends and Twitter after the episode and constructed an autoregressive integrated moving average algorithm to calculate search volumes had Kimmel not aired the episode.ResultsGoogle searches and the number of Tweets for tetralogy of Fallot increased by 3063.27% and 4672.62%, respectively, above expected.ConclusionsOur findings indicate that television talk shows may represent strong outlets for increasing public awareness of rare disorders.

Artificial skyglow, the brightening of the night sky by artificial light at night that is scattered back to Earth within the atmosphere, is detrimental to astronomical observations and has an impact on ecosystems as a form of light pollution. In this work, we investigated the impact of the lockdown caused by the COVID-19 pandemic on the urban skyglow of Berlin, Germany. We compared night sky brightness and correlated color temperature (CCT) measurements obtained with all-sky cameras during the COVID-19 lockdown in March 2020 with data from March 2017. Under normal conditions, we expected an increase in night sky brightness (or skyglow, respectively) and CCT because of the transition to LED. This is supported by a measured CCT shift to slightly higher values and a time series analysis of night-time light satellite data showing an increase in artificial light emission in Berlin. However, contrary to this observation, we measured a decrease in artificial skyglow at zenith by 20% at the city center and by more than 50% at 58 km distance from the center during the lockdown. We assume that the main cause for the reduction of artificial skyglow originates from improved air quality due to less air and road traffic, which is supported by statistical data and satellite image analysis. To our knowledge, this is the first reported impact of COVID-19 on artificial skyglow and we conclude that air pollution should shift more into the focus of light pollution research.

Astrotourism is considered to be a modern form of ecotourism. The main resource for astrotourism is a high-quality night sky, but this is very sensitive to natural as well as anthropogenic factors; for example, land utilization and expansion of urban areas often cause the negative effect of light pollution. The aim of the study is to perform a lighting survey by night sky brightness (NSB) measurements using the sky quality meter (SQM-L) at 20 study sites of the Slovenské stredohorie Upland region (Slovakia) and to assess the region’s potential for astrotourism development (PAD) using a multicriteria analysis. The NSB values ranged from 19.90 (city Žiar nad Hronom at Žiarska kotlina Basin) to 21.54 mag/arcsec2 (recreation area Poľana at Poľana Mountains). At 14 out of 20 study sites, the NSB values even reached 21.2 mag/arcsec2, as recommended by the International Dark-Sky Association for dark-sky parks. Four study sites were categorized as sites with medium PAD, and sixteen with low PAD. No study site reached a high or very high PAD. The best conditions for astrotourism development are fulfilled mainly by the Poľana Mountains geographical unit. The findings can be used for sustainable astrotourism development, land management, and planning to ensure socioeconomic development, together with nature and dark-sky conservation.

<p>Pluvial floods are one of the most significant natural hazards in Europe causing severe damage to urban areas. Following the projected increase in extreme precipitation and the ongoing urbanization, these events play an important role in the ongoing flood risk management discussion and provoke serious risk to the public as well as to the insurance sector. However, this type of flood, remains a poorly documented phenomenon. To address this gap, Swedish Pluvial Modelling Analysis and Safety Handling (SPLASH) project aims to develop new methods and types of data that improve the possibility to value flood risk in Swedish municipalities by collaboration between different disciplines.</p><p>SPLASH project allows to investigating the impact of heavy precipitation along the entire risk modelling chain, ultimate needed for effective prevention. This study presents a pluvial flood catastrophe modelling framework to identify and assess hazard, exposure and vulnerability in urban context. An integrated approach is adopted by incorporating ‘rainfall-damage’ patterns, flood inundation modelling, vulnerability tools and risk management. The project is developed in the ‘OASIS Loss Modelling Framework’ platform, jointly with end-users from the public sector and the insurance industry.</p><p>The Swedish case study indicates that the framework presented can be considered as an important decision making tool, by establishing an area for collaboration between academia; insurance businesses and rescue services, to reduce long-term disaster risk in Sweden.</p>

This article deals with the issue of achieving the goals of ecological education in the context of the fable The Wolf Called Ambaras by Tomasz Samojlik and its influence on shaping pro-ecological attitudes of children and adolescents towards wolves. The fable The Wolf Called Ambaras by Tomasz Samojlik is part of the literature trend promoting pro-ecological attitudes within the framework of ecological education. The main educational goal included in the story of the fable treating the adventures of the young wolf is to provide young readers and their parents the knowledge about the wolves’ life as well as public awareness of the need to protect the wolf by shaping positive attitudes of people towards this predator. Helpful in this assumption is taking up the problem of overthrowing negative stereotypes about wolves, on which the form of answers as well as attemption of demythologizing them are individual scenes of the fable. The plot of the analyzed fable attempts to answer the three main allegations of people towards wolves, which often appear in social, political and ecological discourse: the issue of wolves attacks on people, the impact of wolves hunting on forest game population and the public perception of a wolf as a bad animal, one unnecessary in the ecosystem. In addition, the bibliotherapeutic character of the fable was indicated. Through identificaiton with the character of the fable, readers can overcome their own fears related to their weaknesses and complexes based on the desensitization.

INTRODUCTION The article intends to identify the factors that can retain talented people and attract new talent in small and medium-sized urban areas of European scale, especially in regions with declining and ageing populations. The problem is topical in today's Europe and as well as in Japan. It is equally important to understand the skills needed and the sectors where talents are required in small and medium-sized urban areas with an ascending development trend. The theoretical background of the research is based on literature studies on the theory of talent flow, knowing the factors of the talent flow in small and medium-sized cities, and building the talent flow models based on them. The article discusses the concept of talent (Michaels et al. 2001, several dictionaries, understanding of Valmiera residents). The researchers define that talented people fascinate others, create and implement ideas and have good reasoning skills. Until now, mainly in Europe and in the USA, the attraction of talent at the level of cities and regions has been implemented through migration policy. The administrative boundaries where the migrant talents come from are not as important as the factors that encourage the decisions on the choice of the place of living and work. In Estonia a National Policy for Attracting and Retaining International Talents (2014) has been developed. The findings of the report on models for attracting talent in Europe through the public sector are relevant to small and medium-sized urban areas. In the case study, there are no respondents representing a migrant group that is not a diaspora, and this is a specific feature of a small and medium-sized urban area. MATERIALS AND METHODS The empirical part has been developed through a study in Valmiera City (Latvia, Europe) with a population of 23 thousand inhabitants, aiming at increasing this number by 5000 and further boosting growth  in the city's competitiveness in human resources. A survey of 25 experts was conducted initially to highlight the trends. In order to obtain the data, 29 interviews were conducted with the city's entrants, outgoing residents and the steady, already stable and welcoming residents of Valmiera. Also, an online survey of 81 university graduates was carried out to find out the major reasons for staying in or leaving the regional city of Valmiera. The research city of Valmiera was compared to Ventspils, Rezekne and Jelgava in Latvia, as well as to two foreign cities in Northern Europe – the nearest neighbouring city of Tartu in Estonia and Joensuu in Finland. The cities were compared by socio-economic factors - population dynamics, economic development, access to culture, and political stability, which are important factors in attracting talent. The research methodology is based on the theoretical findings of Ingram, Shapiro, Albouy on the impact of four dimensions in talent attraction: economic development, market competition, labour market conditions and national culture, as well as the impact of lifestyle on choice. According to these dimensions, interview questions have been developed, and, by grouping the content, the analysis of the responses has been carried out. The previous study by the authors has been used as a secondary source. The study focused on the future skills needed for the labour force in the Vidzeme region in Latvia, and the compliance of the proposed education with the labour market requirements in the Vidzeme region of Latvia. RESULTS The results of the research show that a job offer providing the applicant the  possibility to demonstrate his capacity and pursue his or her objectives is of primary importance for the recruitment of skilled labour in a winning city in a rural area, followed by the appropriate housing and transport, and social infrastructure. As a secondary factor, lifestyle, which includes diversity, cultural environment, architecture and the presence of the natural environment, is important. The importance of the factors of attraction varies according to the stage of human life. DISCUSSION The results of the interviews show that small and medium-sized urban areas have the potential to attract talented human resources, taking into account the key attraction factors described in the theory. The empirical analysis in the example of Valmiera reveals that a significant attraction factor in small and medium urban areas is social ties with the area. The labour market demand is also an important factor. The results of the research revealed that in certain occupational groups in Valmiera (such as managers, social sciences in general), the labour market demand is lower than the supply. In further research it would be necessary to carry out focus group interviews with migrants in small and medium-sized urban areas in order to find out the important factors in taking a decision on their choice of residence. CONCLUSION Small and medium-sized urban areas need to develop diversity and openness. This initiative needs to be strengthened both in the operation and investments of a municipality and in communication with the public. Virtually all of the examples discussed refer to migration as inevitable in attracting talent – highly skilled people.

The impact caused in the tourism sector by the public health crisis linked to coronavirus COVID‑19 and the need to protect the population from subsequent infection marks a necessary change in the model of tourism in coastal areas in Spain where mass tourism was the norm. Relevant reforms must be made to soften the economic effects of the drop in foreign tourism. In the case of cultural tourism in urban areas and inland, there is an en excellent opportunity to make structural changes in management that pre‑Covid was already experiencing serious problems. In this document we attempt to highlight the elements that may be key to future reform.

The rapid development of technology coupled with humanity’s desire to reach beyond terra firma, has resulted in more than 60 years of Outer Space activities. Although the exploration of space has provided many advantages and benefits to society so far, including vast, new information that has greatly added to our understanding of our planet and beyond, unfortunately, mankind’s footprint has negative aspects that need to be minimised as much as possible. In recent decades, a major worldwide problem has emerged in regard to the significant increase in light pollution from ground-based illuminations, as well as a lack of proper regulatory frameworks to mitigate the issue in order to protect the night sky and astronomical research. More recently, due to the escalating demand of air space for microsatellites and the rapid development of these new space technologies, as well as unmanned aerial vehicles (UAV), a new problem has arisen connected to visual light pollution (VLP). New Zealand has been especially affected, as, because of its dark skies, it has the third highest number of astronomical observatories in the world. The aim of this research is to identify critical areas for broader investigation; an action plan to improve the impact of new technologies is urgently required, not only at a national level but also worldwide. This is crucial in order to preserve humanity’s right to access the night sky and to also enable continual professional and amateur night-time observations for the present and the future, as well as for New Zealand to become a Dark Sky Nation.

ABSTRACT Circa-monthly activity conducted by moonlight is observed in many species on Earth. Given the vast amount of artificial light at night (ALAN) that pollutes large areas around the globe, the synchronization to the circalunar cycle is often strongly perturbed. Using 2-yr data from a network of 23 photometers (Sky Quality Meters; SQM) in Austria (latitude ∼48°), we quantify how light pollution impacts the recognition of the circalunar periodicity. We do so via frequency analysis of nightly mean sky brightnesses using Fast Fourier Transforms. A very tight linear relation between the mean zenithal night sky brightness (NSB) given in $\mathrm {mag_{SQM}\, arcsec^{-2}}$ and the amplitude of the circalunar signal is found, indicating that for sites with a mean zenithal NSB brighter than 16.5 $\mathrm {mag_{SQM}\, arcsec^{-2}}$ the lunar rhythm practically vanishes. This finding implies that the circalunar rhythm is still detectable (within the broad bandpass of the SQM) at most places around the globe, but its amplitude against the light polluted sky is strongly reduced. We find that the circalunar contrast in zenith is reduced compared to ALAN-free sites by factors of $\frac{1}{9}$ in the state capital of Linz (∼200 000 inhabitants) and $\frac{1}{3}$ in small towns, e.g. Freistadt and Mattighofen, with less than 10 000 inhabitants. Only two of our sites, both situated in national parks (Bodinggraben and Zöblboden), show natural circalunar amplitudes. At our urban sites, we further detect a strong seasonal signal that is linked to the amplification of anthropogenic skyglow during the winter months due to climatological conditions.
