It has been demonstrated in the presented study that the use of services plays a key role in the formation of a new type of the competitive economy based on the information technology and involves the innovation of mutually beneficial commercial interactions. Qualitative and quantitative changes in the content, forms, and mechanism of the workflow management have been investigated in the aspect of the main trends in the development of the monetary relations. The search for the modern business technology predetermined the development of the electronic wholesale market and the possibility to improve the convenience of the service of doing business. The subjects of this sector of commodity circulation confirm the efficiency of the formation of economic relations in the segment of online trade services and the prospects of the electronic business.
The analysis of the electronic market trade workflow allowed to establish the main trends in its development, to identify the specifics of partnerships, their establishment, and the online implementation of trade procedures through the electronic document workflow.
As a result of the study, the authors have established the reasons for the increase in the number of participants of electronic marketplaces, changes in the commodity structure in the corporate procurement sector, the mechanism for reducing purchase prices through electronic auction, and the possibility of optimizing costs and increasing the efficiency of managerial processes in the organization by improving the service automation of business selling processes in a competitive environment.
Based on the comparison of the number of auctions conducted and the amount of deals concluded, it has been noted that the largest number of auctions were held in consumer goods, where the average deal value was the least, while the deals of the highest value were in the provision of services, with the lowest proportion of the conducted auctions.
The authors of the study have analyzed potential commercial and technological risks and identified the main fraudulent schemes in electronic commerce and measures aimed at preventing or eliminating certain risk factors and conditions of uncertainty of the result.
Based on the opinions of the experts, the promising directions for developing the electronic market and electronic wholesale services have been noted in the study, which can be achieved through the creation of independent electronic trading platforms by large industrial corporations, as well as through the use of the information and communication network functions in the internal corporate interaction in large holdings. Combining the capabilities of the marketplaces of the corporate and public procurement sectors and launching a joint service for electronic trading while maintaining established business processes will improve the efficiency of the commercial activities of participating organizations.
Effect of Precrack Configuration and Lack-of-Fusion on the Elastic-Plastic Fracture Toughness of Additively Manufactured Ti-6Al-4V parts

Published: July 2020

Abstract
A comparison between fatigue precracked and sharp-notched Charpy-type fracture toughness specimens is presented for characterizing the elastic-plastic fracture toughness of Ti-6Al-4V parts (produced by electron beam melting, a powder bed fusion method). The effects of processing and postprocessing conditions on crystallographic texture, grain morphology, and elastic-plastic fracture toughness of additively manufactured Ti-6Al-4V parts are currently under investigation at the National Institute of Standards and Technology (NIST) in Boulder, Colorado. The specimens tested in this work were subjected to hot isostatic pressing (HIP) for 2 h at 900°C and 100 MPa in Argon environment (sub-β transus HIP), which is a commercial postprocessing step known to seal internal porosity in additively manufactured Ti-6Al-4V parts. Lack-of-fusion (LoF) pores were still visible after HIP treatment. These specific pores were exposed to the external surfaces and were thus immune to HIP treatment. In this work, the following variables and their effects on room temperature fracture toughness (measured by means of three-point-bending unloading compliance tests on Charpy-type specimens) were specifically addressed: notch configuration (fatigue precrack vs. sharp electrodischarge machining notch), specimens directly attached to the build plate (nonsupported) vs. connected to the build plate using standard thin wafer supports (supported), and LoF content. The results of this preliminary investigation will guide the choices for the remaining fracture toughness characterization of Ti-6Al-4V under various processing and postprocessing conditions.

Published: July 2020

Background: Desmoid tumors are rare and represent 0.03% of all solid tumors. Their histology is benign but they are willingly aggressive with significant locoregional invasions and frequent recurrences.Case presentation: We report the case of a 52-year-old patient who presented with a scapular and pulmonary localization of this tumor, but was stable over time. In view of potentially delaying surgery and stability of the lesions, simple monitoring was decided. The lesions are currently stable, two years after diagnosis. We discuss the clinical, radiological, and therapeutic characteristics of this type of tumor, in the light of data from the literature.Conclusion: Desmoid tumors are rare, benign but aggressive. Surgery is the main treatment but is often decaying. Simple monitoring can be scheduled in case of less aggressive tumors.

AbstractBackground and aimWhereas many studies on Internet gaming disorder (IGD) have used self-report questionnaires, only a few have adopted clinical interviews and samples. The current study aimed at using data from face-to-face diagnostic interviews, based on the criteria for IGD in the DSM-5, to determine the Internet, gaming, and smartphone usage patterns of children and adolescents.MethodsA latent class analysis was conducted using data collected through diagnostic interviews for Internet, gaming, and smartphone addiction with 190 participants (M = 13.14 years, SD = 2.46; 143 boys, 47 girls) who were part of a multicenter clinical cohort study.ResultsParticipants were classified into four groups: pleasure-seeking (Class 1), internal-use (Class 2), problematic-use (Class 3), and pathological-use (Class 4). The pleasure-seeking group (8.11%) showed low tendencies in general and proper control. The internal-use group (17.63%) showed significant increases in “cognitive salience” and “craving,” with strong internal desires. The problematic-use group (37.28%) had no “interference with role performance”; however, they displayed “difficulty regulating use” and “persistent use despite negative consequences,” with a slight functional impairment. The pathological-use group (36.98%) scored the highest on all these items, revealing a severe functional impairment. Compared to the other groups, the pathological-use group had the highest depression and daily stress levels and displayed the lowest levels of happiness.ConclusionsThis study provides basic data to elucidate Internet, gaming, and smartphone overuse patterns among children and adolescents, which could be used to develop differentiated intervention strategies for each group.
Inhibitory neuromodulation of the putamen to the prefrontal cortex in Internet gaming disorder: How addiction impairs executive control
Authors: Wang Min , Dong Haohao , Zheng Hui , Du Xiaoxia , Dong Guang-Heng 
Published: July 2020

AbstractBackground and aimsIndividuals with addictive disorders are usually characterized by impaired executive control, persistent craving and excessive reward-seeking. However, it is unclear whether there is a deviation in the connection pattern among the neural systems implicated in these problem behaviors.MethodsOne hundred thirty-six online gaming players were recruited in the current study (68 Internet gaming disorder (IGD) subjects and 68 recreational game users (RGUs) who served as controls matched on age, sex, years of education, and years of gaming). Dynamic interactions among the reward system (striatum), control system (prefrontal cortex), and the interoceptive awareness system (insula) were calculated and compared when subjects were facing gaming cues.ResultsThe results revealed that RGUs showed a significant positive correlation in the putamen-middle frontal gyrus (MFG)-insula neural pathway when facing gaming cues, which was missing in the IGD subjects. Additionally, dynamic causal modeling (DCM) analysis revealed that the MFG region was more inhibited by the putamen in the IGD subjects relative to the RGUs.ConclusionsThese findings suggest that the inhibitory neuromodulation of the putamen to the prefrontal cortex in IGD individuals undermines the balance among the tripartite systems. Our findings provide novel neurobiological evidence for understanding the internal connection bias of the addicted individual’s neural system and how the addictive disorder impairs executive control; consequently, the pathway from the striatum to the prefrontal cortex may serve as a potential biomarker to predict the risk of developing an addiction.

AbstractBackground and aimsInternet addiction (IA) is common among young students. This study aimed to examine the influence and mechanisms of IA and susceptible personality traits on the impact of suicidal ideation in adolescent students in China.MethodsThis cross-sectional study (09/2012–09/2015) used stratified cluster sampling with “school type” for stratification; 136,266 students from 63 schools completed the questionnaire. Logistic regression analysis was performed to estimate the effect of IA (Young's Internet Addiction Test) and susceptible personality (Barratt impulsiveness scale, Buss & Perry Aggression Questionnaire; and Eysenck Personality Questionnaire-R Short Scale) on suicidal ideation (Scale of Suicidal Ideation).ResultsSuicidal ideation was observed in 20,218 (14.77%) of the students, and IA was detected in 28,836 (21.16%) subjects. Compared with those without IA, students with IA had a higher prevalence of suicidal ideation (P< 0.0001). No planning impulsiveness had a predictive effect on suicidal ideation in the impulsive personality trait, while in the aggressive personality trait, hostility and self-aggression had a predictive effect on suicidal ideation (allP< 0.0001). High psychoticism and neuroticism were impact factors for suicidal ideation, but extroversion was a protective factor (allP< 0.0001).DiscussionThese results highlight the importance of assessing personality traits and reducing IA as a possible means of lessening suicidal ideation. Susceptible personality (such as high psychoticism, high neuroticism, and low extroversion) play a prominent role in influencing the probability of having suicidal behavior among those recently exposed to IA.ConclusionsIA and susceptible personality traits were significantly correlated with suicidal and self-harm ideation among adolescent students.
Changes in health risk associated with air pollution and policy response effectiveness, Richards Bay, South Africa
Authors: Okello Nick O. , Okello Tom W. , Zunckel Mark 
Published: July 2020

Lung and bronchus cancer, asthma, acute lower respiratory infections (ALRI), ischemic heart diseases (IHD), cerebrovascular diseases (CEV) are disorders that have been widely associated with air pollution. More so, research shows that more than 5.5 million people die prematurely every year due to household and outdoor air pollution placing it as the fourth highest-ranking risk factor for death globally (Forouzanfar et al., 2015).
Setting a minimum emission standard for industrial sources is a way to control air pollution and to minimize adverse impacts on people. With an aim to ascertain pollution policy intervention effectiveness, this study uses the case of Richards Bay to determine changes in health risk associated with air quality pollution exposure and the benefits of policy intervention. The study looks at trends of mortality in the last 20 years, the change in the ranking of 6 air-related mortality causes and Year of Life Lost (YLL) as a result of pollution. Results indicate a 24% decrease in the YLL due to air quality related diseases since 2009 when minimum emission standards were promulgated. The decrease can be observed across all age groups except for the 15-24-year-old, where cases of asthma and acute lower respiratory infections (ALRI) are the major mortality drivers. The adults and the older generation are now living slightly longer, although cases of CEV in that generation as well as the younger generation is still an issue that requires continuous monitoring and intervention. The study concludes that there is an improvement that could be attributed to policy implementation. However, the increase in mortality due to certain disease cases such as cancer of the bronchus and lung whose onset could be prior to 2010 signifies that the pollution control efforts need to continue and be stepped up. The increase of ALRI, which adversely affects children, is of concern

Published: July 2020

This review analyzes the research data concerning the problem of antibiotic prophylaxis (ABP) of wound infections after various surgeries forhead and neck tumors. In patients with clean wounds, ABP should be used in exceptional cases only (for example, if the patient has any riskfactors), otherwise it should be avoided. A short ABP course is recommended for patients with clean-contaminated wounds; however highrisk patients may require a prolonged course. There is some evidence of ABP efficacy in patients with non-contaminated wounds after cervical lymphadenectomy. When choosing a drug for ABP, a doctor should consider the site of surgery and the risk of wound contamination. Theoptimal drugs after head and neck surgeries include first- and second-generation cephalosporins, ampicillin in combination with sulbactam,metronidazole, and clindamycin. First- and second-generation cephalosporins in combination with metronidazole are preferable, but if thewound is infected with gram-positive bacteria, it is necessary to use clindamycin monotherapy. Reconstructive surgeries with a free flap require a short course of ABP with one of the following combinations: cefazolin + metronidazole, cefuroxime + metronidazole, or ampicillin + sulbactam; if the patient is allergic to beta-lactams, clindamycin can be used. Despite the availability of standard ABP regimens, a surgeonmust apply a tailored approach when choosing an ABP regimen for each patient, taking into account risk factors and the volume of surgery.
The Impact of Additive Technologies on Determining the Tort Liability Model of an Online Platform Operator
Authors: Bogdanov D. E. 
Published: July 2020

In the paper, the author points out that humanity has moved into the era of information society, the era of digitalization, when the digitalization of all socio-economic relations becomes an inevitable global process radically changing the existence of man and even of man himself. In the sphere of Economics, the traditional borders between the producer, seller (intermediary) and consumer of goods are being erased, and the phenomenon of sharing economy is replacing traditional channels and supply chains, radically transforming socio-economic relations. New forms of collaboration between manufacturers, wholesalers, retailers and consumers are emerging, and a new technological infrastructure for such collaboration is actively developing, i.e. digital online platforms that act as one of the drivers of the fourth industrial revolution. The development of the three-dimensional printing technology allows any individual to participate in the creation of various material goods. Printing of material objects is based on a three-dimensional digital model, the digital equivalent of its physical embodiment. A serious legal challenge is the regulation of relations related to the circulation and use of three-dimensional models of objects of the material world, as well as liability for damage caused by a defect in the three-dimensional digital model.The paper contains a number of prognostic conclusions. If a defective three-dimensional digital model is purchased for a fee as a product (digital content) on the corresponding online platform, it is possible to impose tort liability on both the counterparty under the contract and the platform operator. Such liability must be strict, joint and several. A strict, joint and several liability model will serve as an incentive to ensure transparency in the field of digital turnover, as well as exert a preventive influence by deterring illegal behavior. If the identity of the seller of digital content is not established, only the platform operator will be held liable.If a defective three-dimensional digital model is placed free of charge on the hosting site, the creator of such a digital model will be held liable. The responsibility of a hosting provider that provides only a technical service for hosting content must be subject to the rules on the responsibility of the information intermediary.

Remote Work as a Trend of Time: Results of Mass Testing
Authors: Gurova I. M. 
Published: July 2020

Purpose: is to study the experience of mass implementation of remote work (telecommuting) in Russian companies during the isolation regime caused by the COVID-19 pandemic, to assess the opportunities for further development of this type of labor relations and emerging trends in the labor market.Methods: to accomplish the research tasks, universal general scientific methods are used: analysis, synthesis, abstraction, generalization, analogy, comparison, forecasting. The paper uses secondary analysis and interpretation of applied research data related to remote work issues. Also in the study the elements of statistical and structural-functional analysis are used. Results: we have studied the research conducted during the pandemic in relation to the opinions of employers and staff of Russian organizations about the experience of remote work. This made it possible to identify groups of its negative and positive factors. The main problem for everyone was the shortcomings of the organization of the remote work process, which affected the efficiency of labor. The main advantage was the economic benefits of the remote format. According to experts, today Russians have an interest and sufficient readiness for remote work. This is confirmed by the identified characteristics of the domestic labor force and data on the level of their digital literacy. However, on the part of employers, the continuation of this practice raises a considerable number of questions. Their problems are caused by a whole list of organizational factors that can neutralize the positive effect of the introduction of a new type of labor relations. At the same time, experts expect to increase the use of remote work in Russia, as well as expanding the scope of its application. The reviewed foreign experience shows a number of very successful examples of remote activities of English-speaking companies. International research reports predict a further increase in the spread of remote work. This will affect even those countries of the world where remote work was not widespread before the crisis.Conclusions and Relevance: despite the advantages and disadvantages, the practice obtained during the isolation regime revealed the potential of remote work and played a role of a catalyst in the development of this format of labor relations in Russia. Among the main trends emerging in the labor market are: improving the legal framework of remote labor relations, developing forms of remote work and labor management, applying it in new areas of activity and increasing the staff of companies working remotely.

Published: July 2020

Theater und Übertragung stehen in vielfältiger Verbindung zueinander. Nicht nur, dass es Übertragung im Theater gibt – wie es im Titel des preisgekrönten Buches von Eva Holling heisst –, insofern beide von einer gemeinsamen Grundstruktur begehrender Subjekte geprägt sind, vielmehr ist Theater auch Übertragung und weitet sich in dieser auch ständig aus, so wie umgekehrt Übertragung ständige Neu-Inszenierung von Begehren wird. Diese Verdichtung und ihre ständige Verschiebung werden auf kenntnisreiche Weise über verschiedene Formen und Formate von Theaterproduktionen durchkonjugiert. Getragen vom Begehren trägt es sie immer weiter.

Published: July 2020

Ein medialer Star der Veranstaltung im Theater der Künste war Birdly. Virtual Reality war ein Renner. Man stand Schlange, um sich mit der 3D-Brille Flügel anzuschnallen und über und durch New York zu fliegen, so wie man das Fliegen aus Träumen kennt. Der Traum vom Fliegen, der Flug als Traum, der Traum als Flug – alles konnte man erleben. Der Traum als Maschine, diese Maschine als Traum gab Anlass zu einer Diskussion der Übertragungsverhältnisse zwischen Bildern und Realitäten, die mit einem Vortrag von Daniel Rüfenacht zur 3D-Bildgebung und ihrer Bedeutung fürs Verständnis von Aneurysmen ihren Auftakt nahm:
