"BACKGROUND: The COVID-19 pandemic is a public health threat of international concern, intensifying peoples' psychological risk and vulnerability by strengthening mental health stressors such as fear, panic and uncertainty. The unexpected fear of COVID-19 has been reported to be associated with suicide occurrences, similar to prior pandemics.
AIMS: Identifying the factors associated with fear of COVID-19 could help us to develop better mental health strategy and practice to improve the situation here in Bangladesh. This was the first attempt to present a Geographic Information System (GIS)-based distribution of fear of COVID-19 across the country's administrative districts in a nationwide sample.
METHOD: Data for a total of 10 067 individuals were collected by an online survey during the first wave of the pandemic (1 to 10 April 2020); data for 10 052 participants were finally analysed after excluding 15 transgender individuals. The survey questionnaire included items concerning sociodemographic, behavioural and health-related variables, COVID-19-related issues, and the Bangla Fear of COVID-19 Scale.
RESULTS: The mean fear of COVID-19 scores was 21.30 ± 6.01 (out of a possible 35) in the present sample. Female gender, highly educated, non-smoker, non-alcohol consumer, having chronic diseases, using social media, and using social media and not using newspapers as COVID-19 information sources were associated with a higher level of fear of COVID-19. Higher levels of fear of COVID-19 were found in districts of Magura, Panchagarh, Tangail, Sunamganj and Munshiganj; by contrast, Kushtia, Pirojpur, Chapainawabganj, Jhalokathi and Naogaon districts had lower fear of COVID-19. Based on the GIS-distribution, fear of COVID-19 was significantly associated with the district as well as in respect to its gender-based and education-level-based associations. However, fear of COVID-19 and COVID-19 cases were heterogeneously distributed across the districts; that is, no consistent association of higher COVID-19 cases with higher fear of COVID-19 was found.
CONCLUSIONS: This study being exploratory in nature may help to facilitate further studies, as well as directing governmental initiatives for reducing fear of COVID-19 in at-risk individuals. Providing adequate resources and mental health services in the administrative regions identified as highly vulnerable to fear of COVID-19 is recommended."

This paper provides a schematic, conceptual trip across a set of paradigms that can be adopted to design flood control actions and the associated river setting, including the space allocated to the river. By building on such paradigms, it eventually delineates an integrated approach to identify a socially desirable river setting, under a climate changing reality. The key point addressed is that when residual Risk and Operation, Management and Replacement costs are considered to their full extent, even a basic economic analysis may suggest alternative river settings that can be more attractive, particularly if accompanied by suitable economic-administrative management measures. Emphasis is put on the deep uncertainty characterizing the whole decision problem and on the need for a drastic change of paradigm. The approach proposed can greatly improve current Flood Risk Management Plans responding to the European Flood Directive (Directive 2007/60/EC). It can also help to develop constructive dialogues with stakeholders, while enhancing the understanding of the problem. Although mainly intended to address a conceptual level, it also aims at providing an applicable method.

The influence of Karun river inflow on salinity intrusion from the Arabian Gulf towards the upper reaches of the Shatt Al-Arab river estuary was evaluated by using Mike11, a one-dimensional numerical modeling technique. The simulations results indicated that, during the moderate and low flow conditions of the Shatt Al-Arab river, freshwater inflow from Karun river at 10 and 40 m3/s, respectively, could be capable of keeping salinity extent to not exceeded the confluence location of these two rivers. Additionally, the results indicated that in the case of a sharp decline of Karun river inflow, additional releasing of freshwater from the Tigris river can completely compensate for the Karun inflow. While in the case of cut off of Tigris river, the Karun inflow in the range of 60 m3/s could be able to keep salinity extent beyond the Abo Flous station during the simulation period. Furthermore, the possibility of discharging water with high levels of salinity from the farming projects located at the lower basin of Karun river towards the Shatt Al-Arab river estuary was taken into account. In such cases, the results suggested that during low and moderate flow conditions, freshwater inflow by about 250 and 225 m3/s, respectively, should be released from the Karun river to remains salinity extent below the Abo Flous location. A water management policy agreement between Iraq and Iran could be an effective solution to the salinity issue both in the Shatt Al-Arab river estuary as well as Karun river.

New investigations in the Western Caucasus contribute to the understanding of granite pseudokarst (sensu lato) and megaclasts linked to river erosion. A plot on the bank of the Belaya River (Mountainous Adygeya, Western Caucasus) was selected to examine diverse and abundant pseudokarst features (small rock basins, hollows, potholes, and channels) and large clasts. Morphological analysis of these features clarifies their general characteristics and genetic interpretations. Pseudokarst features can be classified into two major categories, namely the relatively small (<1 m) and large (>1 m) features. Potholes, which are usually 1–3 m in size, are the most characteristic features occurring on two levels, i.e., on steep walls of the gorge (half-filled with river water) and on slightly inclined surfaces of a terrace-like landform (subaerial exposure). In both cases, their walls from the side of the river are broken. Apparently, these potholes were formed on the river bottom. Subsequent incision of the gorge elevated potholes and the river has eroded them from one side. Apparently, some pseudokarst features are related to macroturbulent flood flows and granite weathering. Due to its scientific uniqueness and aesthetic attractiveness, this granite pseudokarst constitutes geoheritage, which can be exploited for the purposes of geoscience research and geotourism development.

Spatial media bring out new forms of interaction with places, leading to the emergence of new ways of embodying the experience. The perception of place and its dynamics of change has been multiplied by the emergence of digital platforms, which create many and varied representations of place in spatial media. These representations are dependent on the digital platforms’ ecosystem, formed by platform-specific mechanisms of digital placemaking. The study applied text mining techniques and statistical methods to explore the role of user-generated content as a digital placemaking practice in shaping place experience. The online reviews were collected from Google Maps for 23 places from Poznań, Poland. The analysis showed that place experience is described by three dimensions: attributes, practices and atmosphere, or place practices that most closely reflect the specificity of a place. The place attributes blurred the boundaries between their digital images, whereas the atmosphere dimension reduces the diversity and uniqueness of the place. In conclusion, user-generated content (UGC) as an element of the process of digital placemaking increases place awareness and democratizes human participation in its creation, yet it affects its reduction to homogeneous information processed through mechanisms operating within a given digital platform.

The magnitude of highly dynamic spatial data is expanding rapidly due to the instantaneous evolution of mobile technology, resulting in challenges for continuous queries. We propose a novel indexing approach model, namely, the Velocity SpatioTemporal indexing approach (VeST), for continuous queries, mainly Continuous K-nearest Neighbor (CKNN) and continuous range queries using Apache Spark. The proposed structure is based on a selective velocity partitioning method, i.e., since different objects have varying speeds, we divide the objects into two sets according to the actual mean speed we calculate before building the index and accessing data. Then the adopted indexing structure base unit comprises a nonoverlapping R-tree and a two dimension grid. The tree divides the space into nonoverlapping minimum bounding regions that point to the grids. Then, the uniform grid stores the object data of leaf nodes. This access method reduces the update cost and improves response time and query precision. In order to enhance performances for large-scale processing, we design a compact multilayer index structure on a distributed setting and propose a CKNN search algorithm for accurate results using a candidate cell identification process. We provide a comprehensive vision of our indexing model and the adopted query technique. The simulation results show that for query intervals of 100, the proposed approach is 13.59 times faster than the traditional approach, and the average time of the VeST approach is less than 0.005 for all query intervals. This proposed method improves response time and query precision. The precision of the VeST algorithm is almost equal to 100% regardless of the length of the query interval.

‘In the Theatrical World our talk is all of holidays.’ So opened one of Hearth and Home magazine’s gossip columns in July 1897. The holidays taken by London’s late-Victorian West End theatre stars attracted regular press coverage and formed a regular subject of letters between actresses, actors and their friends. The narratives of hard work and public service that had played a significant role in improvements in the theatre industry’s reputational and cultural status prompted a secondary narrative around rest: a widely shared understanding that rest was necessary to counter the impacts of the ongoing on- and off-stage labour undertaken by stage stars. Together newspaper accounts and correspondence capture both industry-focused concerns about the maintenance of the strong physical and mental health required to sustain a theatrical career and social disquiet around the changing world of work more widely and patterns of overwork and exhaustion. In this essay I consider a range of press accounts and correspondence to consider how evidence of stage stars’ holidays can extend our understandings of the professional culture of the late-Victorian theatre industry and theatre’s contribution to wider social and political ideas surrounding work and rest, and physical and mental health.

The history of a garden is a narrative constructed on the basis of factual evidence, but also shaped by shifting ideological pressures and historical circumstances over the long durée of its existence. The study of the reception or afterlife of a particular garden allows us to see how it changed over time, was reformulated by its visitors, and how these changes have influenced its subsequent interpretations.1 Despite this widely shared understanding, the afterlife of the Sacro Bosco at Bomarzo has received little critical attention, though its complex historiography was inseparably tied to political and social shifts in twentieth-century Italy.

This essay re-examines the once promising idea that style analysis can provide an independent source of insight into an artifact's non-stylistic context. The essay makes explicit the consequences of treating collective style as such a source in archaeology and anthropology of art, and further develops a new framing for the idea that avoids the criticisms largely responsible for the decline in theoretical interest in the epistemic import of visual style analysis since World War II. This re-framing proposes that inference from style to context is permissible on those occasions when a collective style signals by its morphology its suitability to serve a certain function. And it does so because it prescribes publicly certain modes of behavior or spectatorship. Furthermore, the public nature of the signaling may be such that it allows even uninitiated spectators to get a sense of it and thus to gain access to some of the motivations and norms informing the collective's form of life.

This article investigates the role of the darkroom in the experiences of British amateur photographers who, between the 1880s and 1900s, chose to process their negatives themselves while travelling. It focuses, in particular, on the reasons underpinning the development of a network of facilities for changing and developing plates available to tourists, and on how photographers’ engagement with this infrastructure expanded its function in ways that implicitly challenged dominant approaches to both photography and travel. It does so by examining the darkroom, first, as an alternative tourist bureau that put travelling photographers in contact with local knowledge, and second, as the site of a material culture that empowered photographers. These experiences demonstrate that close to the heart of these practitioners was not simply photographic mobility but, most importantly, photographic autonomy.
