The article explores the issue of institutional provision for the employment of unmanned passenger aerial vehicles with electric propulsion (urban electric aerial vehicles) in Ukraine. The use of such vehicles is considered a promising direction in the development of urban air transport, able to unload traffic bottlenecks of the transport system in megacities. Among the main factors that favorably distinguish urban electric aerial vehicles from traditional air transport are: safety, economic efficiency, quietness, environmental friendliness and low requirements for related infrastructure. Preparations for large-scale use of urban electric aerial vehicles are currently being carried out in Germany, the USA, South Korea and the city of Dubai. The analysis of the advantages and possibilities of using urban electric aerial vehicles is provided; the history of development and the current status of this transport type is carried out. Despite the fact that the first samples of urban electric aerial vehicles are only being tested, there is already a significant competition in this market. Among the main developers of this class of aircraft one can single out the companies EHang (PRC) and Lilium GmbH (Germany). The article reviewes legislative requirements for the use of unmanned aerial vehicles with electric propulsion in certain countries of the world. Borrowing this experience can be useful for Ukraine due to the lack of terminological definition of such a class of vehicle in the natonal legislation; uncertainty of the conditions of their operation and safety measures; lacunas in the existing classification of unmanned aerial vehicles, which does not provide for the existence of programmable aerial vehicle, the control of which does not require a special control station located outside the vehicle, or vehicles that carry out programmable flight. In order to eliminate existing lacunas in Ukrainian legislation, measures have been developed, the implementation of which will allow the use of unmanned passenger aerial vehicles with electric propulsion and will contribute to the further development of air transport in Ukraine.

The article discusses the content and the history of modern women’s movement in the USA. The review of the American sociological literature was conducted to make a definition of the term “women’s movement”. The article provides a comprehensive analysis of the main periods in the development of the women’s movement that are referred to by the American researchers as waves. The review of the history of the women’s movement identified and characterized three waves of the women’s movement in the Unites States based on their goals, scale of activity, methods and results of the struggle for the gender equity in the American society. The author analyzed the large-scale network of American women’s organizations and formulated their typology based on their goals and functions. The article outlines the perspectives of the American modern women’s movement further development.

The future looks bright for unmanned aerial vehicles (UAVs). Their ability to carry sophisticated imaging equipment attached to lightweight vehicles, to hover in position despite incremental weather conditions, to fly simple missions, and takeoff and land automatically, combined with their comparatively (compared to manned aircraft) lower investment and operational costs has driven a paradigm shift in the history of air transport. This chapter is organized around six themes that underscore the current discourse regarding the future of UAVs in civilian commercial operations, as well as highlighting the discussions of the previous chapters regarding policy and certification, technology, training, social and economic forces, air cargo, and the effect of UAVs on other sectors of the air transport industry.

This chapter extends the book’s insights about nature, technology, and nation to the larger history of the modern period. While the modern nation loses its grip as a locus of identity and analysis, attempts to understand the operation, disruption, and collapse of continental and global infrastructures continue to mix the natural and the machinic in ways that define them both. Those vulnerabilities emphasize large-scale catastrophe; historiographically, they mask the crucial role of small-scale failures in the experience and culture of late modernity, including its definition of nature. Historical actors turned the uneven geographical distribution of small-scale failures into a marker of distinctive local natures and an element of regional and national identity. Attending to those failures helps not only situate cold-war technologies in the larger modern history of natural and machinic orders; it helps provincialize the superpowers by casting problematic “other” natures as central and primary.

The last decade has seen an exponential increase in the application of unmanned aerial vehicles (UAVs) to ecological monitoring research, though with little standardisation or comparability in methodological approaches and research aims. We reviewed the international peer-reviewed literature in order to explore the potential limitations on the feasibility of UAV-use in the monitoring of ecological restoration, and examined how they might be mitigated to maximise the quality, reliability and comparability of UAV-generated data. We found little evidence of translational research applying UAV-based approaches to ecological restoration, with less than 7% of 2133 published UAV monitoring studies centred around ecological restoration. Of the 48 studies, > 65% had been published in the three years preceding this study. Where studies utilised UAVs for rehabilitation or restoration applications, there was a strong propensity for single-sensor monitoring using commercially available RPAs fitted with the modest-resolution RGB sensors available. There was a strong positive correlation between the use of complex and expensive sensors (e.g., LiDAR, thermal cameras, hyperspectral sensors) and the complexity of chosen image classification techniques (e.g., machine learning), suggesting that cost remains a primary constraint to the wide application of multiple or complex sensors in UAV-based research. We propose that if UAV-acquired data are to represent the future of ecological monitoring, research requires a) consistency in the proven application of different platforms and sensors to the monitoring of target landforms, organisms and ecosystems, underpinned by clearly articulated monitoring goals and outcomes; b) optimization of data analysis techniques and the manner in which data are reported, undertaken in cross-disciplinary partnership with fields such as bioinformatics and machine learning; and c) the development of sound, reasonable and multi-laterally homogenous regulatory and policy framework supporting the application of UAVs to the large-scale and potentially trans-disciplinary ecological applications of the future.

In his address to the Annual Conference of the Australian Behaviour Modification Association in 1986, Dr. Robin Winkler chose the topic “The social history of behaviour modification in Australia” (Winkler & Krasner, 1987). Dr. Winkler was concerned to recognise the contributions of a number of individuals who were prominent in the new movement in the 50s, 60s and 70s. My aim is rather different. I want to try to capture what the early workers were trying to achieve, what they saw as the problems, and how they viewed the early developments. I will then look at more recent developments in Australian behaviour therapy, and try to characterise its current status. Finally, I'll discuss what seem to me the major current problems, and suggest some possible solutions. Where I feel able to do so, and it seems to me appropriate, I'll make some comparisons with the situation in the USA. Many of the more general points, of course, will be relevant to behaviour therapy in any country.

Mapping the characteristics and extent of environmental conflicts related to land use is important for developing regionally specific policies. However, because it is only possible to verify the frequency of conflicts on a specific predetermined subject, it is difficult to determine the various reasons for conflicts in a region. Therefore, this study mapped the current status of regional environmental conflicts in South Korea using a spatial text mining technique, then proposed relevant management policies. The results were obtained by analyzing environmental conflict data extracted from the online agendas of regional environmental organizations. Air quality-related conflicts in South Korea are concentrated in western municipalities; development-related conflicts are concentrated in the southern region of Jeju Island; and intensive safety-related conflicts occur in metropolitan areas, particularly Ulsan. Thus, the type of conflict is determined by the local environment, in accordance with the definition of environmental conflict, and the distribution is determined by the location of the stakeholder population. This study reveals the issues and locations related to local environmental conflict that require further attention, and proposes more wide-ranging methods for managing the links between conflicts by mapping environmental conflicts on a large scale rather than on an individual basis.
