With the growing role of online multi-participant collaborations in shaping the academic, professional, and civic spheres, incorporating collaborative online practices in educational settings has become imperative. As more educators include such practices in their curricula, they are faced with new challenges. Assessment of collaborations, especially in larger groups, is particularly challenging. Assessing the quality of the collaborative “thought process” and its product is essential for both pedagogical and evaluative purposes. While traditional quantitative quality measures were designed for individual work or the aggregated work of individuals, capturing the complexity and the integrative nature of high-quality collaborative learning requires novel methodologies. Network analysis provides methods and tools that can identify, describe, and quantify non-linear and complex phenomena. This paper applies network analysis to the content created by students through large-scale online collaborative concept-mapping and explores how these can be applied for the assessment of the quality of a collective product. Quantitative network structure measures are introduced for this purpose. The application and the affordances of these metrics are demonstrated on data from six large-group online collaborative discussions from academic settings. The metrics presented here address the organization and the integration of the content and enable a comparison of collaborative discussions.

The role of comprehensive cardiac rehabilitation (CCR) is well established in the secondary prevention of cardiovascular diseases such as coronary artery disease and heart failure. Many clinical trials demonstrated effectiveness of CCR in improving exercise capacity, quality of life, and in reducing cardiovascular mortality and morbidity. However, even before the era of the COVID-19 pandemic comprehensive cardiac rehabilitation program’s implementation, especially the second phase, had many barriers. One of the main reasons for not attending in second phase of CCR was lack of transportation from patient’s home to rehabilitation centers. Additionally, in recent months COVID-19 pandemic has led to closure of many cardiac rehabilitation centres resulting in many eligible patients unable to participate in the optimisation of secondary prevention. During the coronavirus disease-2019 pandemic, hybrid telerehabilitation has become the leading solution in the cardiac rehabilitation programs. The present paper contains key information about structures, effectives and safety of hybrid telerehabilitation during the COVID-19 era.

The effect of an artist’s prestige on the price of artwork is a well-known, central tenant in art market research. In considering how an artist’s prestige proliferates, much research examines networks, where certain artistic groupings and associations promote individual member’s artistic standing (i.e., “associative status networks”). When considering the role of associative status networks, there are two models by which status may increase. First, the confirmation model suggests that actors of similar status are associated with each other. Second, the increase model suggests that a halo effect occurs, whereby an individual’s status increases by association with higher-status artists. In this research, we examine the association of artists through museum exhibition to test confirmation versus increase models, ascertaining whether prestige acquisition is a selection or influence process. This research capitalizes on the retrospective digitization of exhibition catalogues, allowing for large-scale longitudinal analysis heretofore unviable for researchers. We use the exhibition history of 1148 artists from the digitized archives of three major Dutch museums (Stedelijk, Boijmans-Van Beuningen, Van Abbe) from 1930 to 1989, as well as data on artists’ market performance from artprice.com and bibliographic data from the WorldCat database. We then employ network analysis to examine the 60-year interplay of associative status networks and determine how different networks predict subsequent auction performance. We find that status connections may have a point of diminishing returns by which comparison to high prestige peers increases one’s own prestige to a point, after which a high-status comparison network becomes a liability.

The role of prerequisites in the development of the transport infrastructure of the capital of Ukraine is revealed. The author formulated methodological approaches to them. A comprehensive geographical description of the prerequisites for the development of the transport infrastructure of the Kyiv city agglomeration was carried out. It has been established that the main limitations are economic factors, which is caused by the highest cost of land resources in Ukraine precisely within this urban agglomeration. Natural factors continue to play a significant role only when carrying out specific prospecting for laying various types of infrastructure objects within it. There are new factors in the functioning and development of transport infrastructure. These include, first of all, the formation of united territorial communities. Their boundaries should be brought to life and their socio-economic development plans and spatial schemes should be developed. Thus, it is necessary to take into account local needs in the development of transport infrastructure with the general needs of the entire Kyiv city agglomeration. A significant role is played by the ownership of land. The concentration of land ownership in the hands of speculators and large developers leads to a sharp rise in the cost of the robot to acquire the necessary land for the construction of a new infrastructure. As a result, many new large residential areas do not have the necessary access roads and they are not connected to the citywide communications system. This leads to significant new problems for the solution of which it is necessary to coordinate new large-scale housing construction with the laying infrastructure. The main problem remains transport accessibility. Laying of highways to new buildings should be carried out at the expense of local budgets. However, there is often a conflict of interest between developers and local authorities. The latter do not want to invest substantial funds in the construction of roads and other types of infrastructure due to the fact that the cost of new relevant construction is much higher than the cost of housing built at the expense of borrowed funds. Thus, the existing suburban transport infrastructure takes on an ever-increasing stream of new daily commuter migrants. As a result, the quality of services provided drops sharply. This leads to a deterioration in the quality of life throughout the urban agglomeration.

The article analyzes the promising directions of development of social movements to support the innovative evolution of the population’s life safety system. The key aspects of the activities of veterans organizations aimed at the transfer of life and professional experience are considered. The assessment of practical experience and prospects of joint actions of volunteers in areas of large-scale disasters with the use of the latest innovative technologies is carried out. The role of social movements in the implementation of modern approaches in the education of younger generations, increasing the involvement of all segments of Russian society in the formation of a culture of life safety and improving the new quality of socio-economic development of the country’s regions is studied. Based on his own practical experience, the author comes to the conclusion about the absolute effectiveness of cooperation between the state and public organizations, involving volunteers in ensuring the safety of life. The analysis of the necessary measures on the part of the state to ensure full cooperation with volunteer movements is carried out, and a set of measures to achieve these goals is proposed. Creation of stimulating conditions for public voluntary fire protection associations at the level of the Russian Federation’s regions as a unique public-rescue institution is noted.

Purpose Drawing on data from a unique, large-scale survey, the purpose of this paper is to examine the links between e-HRM and perceived labour productivity both directly and through the mediating role of HR service quality amongst commercial-bank workplaces in Pakistan, many of which have introduced e-HRM. Design/methodology/approach The authors use partial least squares structural equation modelling to examine the direct links between e-HRM and productivity as well as the mediated links between e-HRM, perceived HR service quality and productivity. Findings The authors show that e-HRM practices have a statistically significant, positive effect on managers’ perceptions of labour productivity. The authors also reveal that e-HRM practices influence the quality of HR service, and that the quality of HR services fully mediates the relationship between e-HRM practices and managers’ perceptions of labour productivity. Practical implications The results highlight the importance of designing and implementing e-HRM systems so that they support organisation workflow and enable workers to carry out a range of HR and non-HR activities more efficiently. In particular, this study suggests that managers should focus on how e-HRM impacts on HR service quality in a holistic way, as this is the “route” via which e-HRM can improve labour productivity. Originality/value Existing research has demonstrated a link between e-HRM and the quality of HR services; however, these studies downplay the potential impact of e-HRM on labour productivity, a key organisational outcome and one that e-HRM aims to improve. This study contributes to the HRM literature by identifying how e-HRM can improve labour productivity by enhancing the perceived HR service quality. This study, therefore, provides the basis for future theory developments in this area.

A modification of the potassium pyroantimonate (PA) method for localization of calcium and sodium was tested using skeletal muscle of mouse. Massive diffusion of these cations, depending on the method of fixation, was demonstrated by analytical ion microscopy (AIM) images on the optical microscopy level. Rapid penetration of the fixative appeared to be the principal condition that reduced diffusion of Ca2+ and Na+. Paraformaldehyde (2%) appeared more efficient than glutaraldehyde (1%) for preserving metal composition. Addition of 1% phenol strikingly improved the quality of the AIM images. Supersaturated PA (4%) appeared to retain about 10 times more sodium in the tissue than insaturated PA (2%). The role of different buffers is also discussed, particularly collidine, which permitted better preservation of sodium. Fixation with this buffer should be very useful for study by AIM of large-scale distribution of sodium. These results are analyzed at the ultrastructural level in the accompanying report.

As Machine Translation (MT) becomes increasingly ubiquitous, so does its use in professional translation workflows. However, its proliferation in the translation industry has brought about new challenges in the field of Post-Editing (PE). We are now faced with a need to find effective tools to assess the quality of MT systems to avoid underpayments and mistrust by professional translators. In this scenario, one promising field of study is MT Quality Estimation (MTQE), as this aims to determine the quality of an automatic translation and, indirectly, its degree of post-editing difficulty. However, its impact on the translation workflows and the translators’ cognitive load is still to be fully explored. We report on the results of an impact study engaging professional translators in PE tasks using MTQE. To assess the translators’ cognitive load we measure their productivity both in terms of time and effort (keystrokes) in three different scenarios: translating from scratch, post-editing without using MTQE, and post-editing using MTQE. Our results show that good MTQE information can improve post-editing efficiency and decrease the cognitive load on translators. This is especially true for cases with low MT quality.

This study focuses on the question of the role of the Caspian Sea at a large scale in the current Russian foreign policy. It is noted that though in the historical perspective the Caspian Sea basin had been totally dominated by Russia since the beginning of the 19th century, this domination was contested and considerably reduced after the collapse of the Soviet Union. Paradoxically, in parallel for various reasons exposed in the paper, the Caspian Sea gained more importance in the Russian foreign policy giving rise to new challenges for the future of the Russian power in the region.

Abstract Every year, due to the salinity resulting from improper irrigation practices, almost 10 billion ha of agricultural lands across the world cannot be used. Among the main elements (cations) for salinity in regions with dry or semi-dry climate are potassium (K+), sodium (Na+), calcium (Ca+2) and magnesium (Mg+’2). Using proper irrigation methods as well as ensuring the quality of irrigation water are of great importance in terms of the salinity of agricultural soils. In this study, laboratory analyses of ground water resources for salinity parameters were conducted in the province of Yalova (Taşköprü, Çiftlikköy, and Altınova regions). In the explanation of the analysis results, variations and effects based on the level of salinity were taken into account and the role of small, meso and large scale factors were determined through the use of the wavelet model. The study results would be of use in the estimation of salinity contents of soils with respect to groundwater irrigation in agricultural areas.
