Landform Units

In this paper, a method for extracting Fenglin and Fengcong landform units based on karst topographic feature points is proposed. First, the variable analysis window method is used to extract peaks, nadirs, and saddle points in the karst area based on digital elevation model (DEM) data. Thiessen polygons that cover the karst surface area are constructed according to the locations of the peaks and nadirs, and the attributes of the saddles are assigned to corresponding polygons. The polygons are automatically classified via grouping analysis according to the corresponding spatial combinations of peaks, saddles, and nadirs in the Fenglin and Fengcong landform units. Then, a detailed division of the surface morphology of the karst area is achieved by distinguishing various types of Fenglin or Fengcong landform units. Experiments in the Guilin research area show that the proposed method successfully distinguishes the Fenglin and Fengcong terrain areas and extracts Fengcong landform units, individual Fenglin units, and Fenglin chains. The Fengcong area covers approximately two-thirds of the whole area, the individual Fenglin area covers approximately one-fourth, and the Fenglin chain area covers approximately one-tenth. The development of Fenglin has different stages in the Guilin area. This study provides data support for the detailed morphological study of karst terrain, and proposes a new research idea for the division and extraction of karst landform units.

The paper discusses the problem of determining the most influential people on social media while taking into consideration the possibilities of forming coalitions with their sets. The authors analyze social media networks created by criminal elements. Modern Russia has a practice of criminal and administrative prosecution of social media users who post information that violates Russian legislation. Today, there is an opportunity to study various aspects of society and obtain new research results using social media, which often play a key role. The authors suggest that the methodology of identifying social media users who are sources of extremist information should be examined and streamlined with the goal of improving the law enforcement practice of counteracting the spread of socially dangerous information on the Internet. They use mathematical methods to show that the problem of finding the maximally influential group consisting of k number of participants cannot have an optimal solution if this group includes k most influential participants individually. To solve this problem, the authors suggest using the game theory concept of Shapley vector, which makes it possible to evaluate the individual contribution of each participant into the formed group, i.e., to find out to what degree each of them could be useful as a team player. Law enforcement bodies already have certain experience of using software to upload data and analyze social networking sites. The presented method of calculating the significance of network users gives an opportunity to widen and improve this experience and to move from the ad hoc selective prosecution of separate users to the methodical work of suppressing and preventing crimes connected with the dissemination of information that constitutes an offence. The research area selected by the authors will, in its turn, contribute to improving the effectiveness of suppressing and preventing crimes connected with spreading information that contains constituting elements of different offences.

After delineating the roots of harmony in the literature from both the Eastern and the Western perspectives, the paper introduces the new Psychology of harmony in terms of harmonization that widens the perspective calling for psychological contributions regarding components, processes and building strengths in a preventive perspective. The complex construction of Harmony from a psychological perspective underlines the concept of relationality. Harmony results at three main points, with oneself, with others, and with nature/the natural world, also taking into account the spatial and temporal perspectives. The Psychology of harmony as harmonization represents a pillar for a new research area in the psychology of sustainability and sustainable development, considering harmonization in geographical and temporal perspectives, including meaningful construction processes from the past, to the present, and into the future using reflexivity processes at the individual, group, community, social, and national levels. Introducing the innovative psychology of harmony as harmonization the present article offers promising perspectives for research and intervention with the aim to individuate and foster new strengths from a preventive perspective.

In this book Barbara J. Risman uses her gender structure theory to tackle the question about whether today’s young people, Millennials, are pushing forward the gender revolution or backing away from it. In the first part of the book, Risman revises her theoretical argument to differentiate more clearly between culture and material aspects of each level of gender as a social structure. She then uses previous research to explain that today’s young people spend years in a new life stage where they are emerging as adults. The new research presented here offers a typology of how today’s young people wrestle with gender during the years of emerging adulthood. How do they experience gender at the individual level? What are the expectations they face because of their sex? What are their ideological beliefs and organizational constraints based on their gender category? Risman suggests there is great variety within this generation. She identifies four strategies used by young people: true believers in gender difference, innovators who want to push boundaries in feminist directions, straddlers who are simply confused, and rebels who sometimes identify as genderqueer and reject gender categories all together. The final chapter offers a utopian vision that would ease the struggles of all these groups, a fourth wave of feminism that rejects the gender structure itself. Risman envisions a world where the sex ascribed at birth matters has few consequences beyond reproduction.

Music neurotechnology is a new research area emerging at the crossroads of neurobiology, engineering sciences and music. Examples of ongoing research into this new area include the development of brain-computer interfaces to control music systems and systems for automatic classification of sounds informed by the neurobiology of the human auditory apparatus. The authors introduce neurogranular sampling, a new sound synthesis technique based on spiking neuronal networks (SNN). They have implemented a neurogranular sampler using the SNN model developed by Izhikevich, which reproduces the spiking and bursting behavior of known types of cortical neurons. The neurogranular sampler works by taking short segments (or sound grains) from sound files and triggering them when any of the neurons fire.

The Impact

PurposeThis study conducts a systematic literature review of e-tail product returns research. E-tail product returns are essentially acquisition of products that have been sold through purely online or brick-and-click channels and then returned by consumer to business.Design/methodology/approachUsing a systematic literature review protocol, we identified 75 peer-reviewed articles on e-tail product returns, conducted bibliometric analysis and content analysis of the articles and summarised our findings.FindingsThe findings reveal that the subject of e-tail returns is a new research area; academics have started to investigate several aspects of e-tail returns through different research methodologies and theoretical foundations. Further research is required in leading e-commerce countries and on key areas such as omni-channel returns management, customer satisfaction and service, the impact of resources such as people skills, the benefits of technology and IT systems in managing e-tail returns.Practical implicationsThe study offers a summative account of current e-tail knowledge areas, which can serve as a reference guide for e-tailers to develop strategies for more efficient and competitive product returns.Originality/valueThis study contributes theoretically by developing clusters of key themes or knowledge areas about e-tail returns. It also provides a conceptual framework for e-tail returns management, which can be used as a springboard for further empirical research.

In recent years, photobiomodulation (PBM) has been recognized as a physical therapy in wound management. Despite several published research papers, the mechanism underlying photobiomodulation is still not completely understood. The investigation about application of blue light to improve wound healing is a relatively new research area. Tests in selected patients evidenced a stimulation of the healing process in superficial and chronic wounds treated with a blue LED light emitting at 420 nm; a study in animal model pointed out a faster healing process in superficial wound, with an important role of fibroblasts and myofibroblasts. Here we present a study aiming at evidencing the effects of blue light on the proliferation and metabolism in fibroblasts and keratinocytes. Different light doses were used to treat the cells, evidencing inhibitory and stimulatory effects. Electrophysiology was used to investigate the effects on membrane currents, while Raman spectroscopy revealed the mitochondrial Cytochrome C (Cyt C) oxidase dependence on blue light irradiation. In conclusion, we observed that the blue LED light can be used to modulate the activity of human fibroblasts, and the effects in wound healing are particularly evident when studying the fibroblasts and keratinocytes co-cultures.

Crucial Part

Entrepreneurship with organization setting has been conceptualized in a variety of ways. Studies in this area remain broad and appear relatively fragmented. From previous literature reviews, we found that little attention has been paid toward the entrepreneurial management model with the starting-up phases of Small & Medium Enterprises (SMEs) in Taiwan. In view of this, the purpose of this study is to fill this gap in the literature by proposing a research framework that integrates both entrepreneurship literature and Small & Medium Enterprises (SMEs) literature. To address this problem, a new research method based on integrating cases study and in-depth interviews methods are also proposed. According to the results, the individual factor was the central part among the four contributing factors (reproduction, imitation, valorization, and venture). With respect to the six dimensions of entrepreneurship (strategic orientation, commitment to opportunity, commitment to resources, control over resources, management frame, and compensation philosophy), the enterprises interviewed in this research all set forth their perspectives. As for the four kinds of entrepreneurial status, there were four entrepreneurial imitation companies and two entrepreneurial venture companies in this research. To conclude, several propositions were proposed, and the results released that the individual factor was the crucial part among the four contributing factors. Research also examined the main dimensions of entrepreneurship for analyzing the theoretical basis.

This essay examines the importance of political ideology for the occurrence of political communication effects on the individual level. It is a common assumption in this research area that people tend to be selective about the political information they expose themselves to and also to selectively process it. Selective exposure and selective perception processes are mainly based on the dominant political orientation of the recipient, which usually leads to a reinforcement of preexisting political perceptions and attitudes. We review recent research on selective exposure and perceptions and argue for greater involvement of findings in social psychology regarding differences in cognitive styles that underlie individual policy orientations and justify why and how these findings can promote the study of partisan selectivity in the reception of political communication. We conclude by highlighting theoretical and methodological perspectives arising from the proposed extension of research on selectivity in the process of receiving political communication.

Combined Strategy

In the modern globalized world migration shows a stable progressing nature which explains the academic interest in this complex, controversial phenomenon. The complexity of migration processes gives rise to new discourses, and a new research area where migration is studied as a social resource, a channel to replenish human resources in the declining regions of the Russian Federation. Data obtained in a complex sociological study performed within the framework of RFFI grant #19-411-340002 “Territorial communities in social transformation: a sociological and managerial analysis” permitted considering migration as a social resource. The research team of the Volgograd Institute of management, a branch of RANEPA, used a combined strategy that includes both quantitative (mass survey of citizens and rural residents) and qualitative methods of empirical study. The former were mass surveys of urban and country residents, the latter - in-depth interviews of experts and representatives of territorial local governing bodies, the academic community, urban and country activists, architects, leaders of property owner associations, long term residents of territorial communities. The obtained data allowed revealing the potential of migration in terms of partial compensation for the declining population of the Volgograd region, replenishing human resources and labor force, preservation and development of regional territories, building solidary ties between the local population and migrants. Migration has both positive and negative implications; the objective, inevitable nature of migration brings to the fore a need for optimal, effective methods of management at all levels of the social system. Social and ethnic agreement between migrants and the receiving population in territorial communities can be only possible when life in a region is well regulated, its municipal structures and local communities function properly, and the traditions and culture of all people residing here are respected.
