Investigating the Influence of Quality Factors on User Satisfaction with Summative Computer-based Assessment
Authors: Bello Hassan , Abdullah Nor Athiyah
Published: December 2021

Computer-based assessment or e-assessment system is an e-learning system where information communication technology is utilized for examination activity, grading, and recording of responses of the examinees. It includes the entire assessment process from the examinees, teachers, institutions, examination agencies, and the public. E-assessment systems have been used extensively in educational and non-educational settings worldwide because of their significant impact on assessment to both the institutions and students. Electronic assessment systems have many significant advantages over conventional paper-pencil-based approaches, like reducing production cost, automatic marking, and fair grading. Other benefits include the ability to conduct adaptive testing, an increase in the frequency of assessment, a large number of people could be examined, low staff requirements during the assessment, and the ability to improve the quality of the evaluation. Text, images, audio, video, and interactive virtual environments in an e-assessment system are all feasible. Nevertheless, given all these advantages, some examinees expressed negative views about electronic assessment in our study due to fear or lack of familiarity with assessment technology and lack of information on e-assessment methods. Despite the increased adoption of e-assessment in higher education and organizations, the examinees' attitudes and opinions need to be studied to implement the system successfully. In an e-assessment environment, several factors account for the evaluation of the system quality. These factors can be categorized into three dimensions: technical, educational, and economical. However, based on literature reviewed,  limited studies attempted to map these quality factors to determine user satisfaction with an e-assessment system. This scarcity of e-assessment satisfaction studies is the gap the study intends to fill. Furthermore, this study's findings would help provide practical and theoretical implications for educational institutions and organizations. This study is among the first application of the Delone and McLean information system success model to predict user satisfaction with computer-based assessment in a developing, African country.

Background Intraoperative rectal injury in prostatectomy patients is an uncommon but severe complication. Particular attention is paid to improving the results of healing damage to the anterior rectal wall during prostatectomy.

Objective To study the morphological features of the parietal pelvic fascia and the rectal wall to substantiate the possibility of the formation of fascial duplication in the elimination of damage to the anterior rectal wall during prostatectomy.

Material and Methods The authors carried out an intravital morphological analysis of the parietal pelvic fascia covering the levator rectum muscle and the anterior rectal wall in 10 men.

Results The parietal pelvic fascia contains more powerful bundles of collagen fibers, which in certain areas are partially woven into the fibers of striated muscle tissue. The adventitia of the rectum is characterized by a looser arrangement of the interacting components of the formed connective and smooth muscle tissue. In the studied formations of the small pelvis, the thickness of collagen fibers separately and in the composition of bundles, as well as the cells of the differon and each fiber separately did not differ, which indicated the identity of their tinctorial properties in the compared zones.

Conclusion Morphological analysis showed that when juxtaposing and touching the edges of the healing area of the surgical wound without tension, a stable and continuous scar of the fascial duplication is formed, which ensures reliable fusion of the stitched anatomical structures.

Published: December 2021

Two clinical cases of surgical treatment of cardiac right-chamber thromboembolism in pregnant women are described. Thromboembolism was diagnosed during a routine examination. In the first clinical case, considering the late pregnancy, a thromboembolectomy was performed under artificial circulation after surgical delivery.

In the second case, thrombus removal from the right atrium was performed on a working heart, without interruption of pregnancy. The surgical and postsurgical period proceeded without any specific features and the patients were discharged from the hospital without any complications. These clinical cases show that it is possible to remove thrombus from the right heart chambers without the use of extracorporeal circulation, which is also safe for the mother and the fetus.
Effective Evidence-Informed Policy: A Partnership among Government, Implementers, and Researchers
Authors: Barrera-Osorio Felipe , Berlinski Samuel , Busso Matías
Published: December 2021

Evidence matters for the effectiveness of public policies,but important informational frictions—that is, resistanceto obtaining or using information on the subject at hand—sometimes prevent it from shaping policy decisions.Hjort et al. (2021) showed that reducing those frictionscan change not only political leaders’ beliefs but alsothe policies they implement. One-way information, fromresearch to policy, may sometimes be insufficient, though.Policymakers may be agnostic about the effectiveness ofan intervention, or they may not know which of its featuresrequire adjustment. A process of policy experimentationmay be needed (Duflo 2017), in which policies arerigorously evaluated at a small scale, the findings of those evaluations inform the policy design, and a new evaluation determines the effectiveness of a fine-tuned version of the intervention, with the assessment continuing until the program is ready to be scaled up. This process requires very close collaboration among government, implementers, and researchers. The means by which evidence is produced is also important. A frequent criticism of researcher-designed interventions is that results may not be relevant. One reason is that pilot programme’s participants or circumstances may be atypical, with the result that the experimental treatment, even if implemented with fidelity, may not achieve similar outcomes in other settings (Al Ubaydli et al. 2017; Vivalt 2017). A second reason is that governments may lack the capability to implement with fidelity interventions tested in randomized control trials. A partnership between policymakers and researchers can help attenuate these concerns. A recent experience in Colombia provides a good example of such a partnership at work. “Let’s All Learn to Read” is an ambitious programme to improve literacy skills among elementary schoolchildren (Grades K–5). Spearheaded by the Luker Foundation, a local nongovernmental organisation, in collaboration with the Secretary of Education of Manizales (Colombia), the programme began with a systematic data collection effort in the municipality’s public primary schools to understand why students were failing to acquire the most basic academic skills. This led to several interventions over many years during which multidisciplinary teams of researchers working in close collaboration with local stakeholders and policymakers designed and evaluated different features of the programme.
Interdisciplinary and transferable concepts in bioinformatics education: observations and approaches from a UK MSc course
Authors: Johnston Iain , Slater Mark , Cazier Jean-Baptiste
Published: December 2021

Bioinformatics is a highly interdisciplinary subject, with substantial and growing influence in health, environmental science and society, and is utilised by scientists from many diverse academic backgrounds. Education in bioinformatics therefore necessitates effective development of skills in interdisciplinary collaboration, communication, ethics, and critical analysis of research, in addition to practical and technical skills. Insights from bioinformatics training can additionally inform developing education in the tightly aligned and emerging disciplines of data science and artificial intelligence. Here we describe the design, implementation, and review of a module in a UK MSc-level bioinformatics programme attempting to address these goals for diverse student cohorts. Reflecting the philosophyof the field and programme, the module content was designed either as ‘diversity-addressing’ – working towards a common foundation of knowledge – or ‘diversity-exploiting’ – where different student viewpoints and skills were harnessed to facilitate student research projects ‘greater than the sum of their parts’. For a universal introduction to technical concepts, we combined a mixed lecture / immediate computational practical approach, facilitated by virtual machines, creating an efficient technical learning environment praised in student feedback for building confidence among cohorts with diverse backgrounds. Interdisciplinary group research projects where diverse students worked on real research questions were supervised in tandem with interactive contact time covering transferable skills in collaboration and communication in diverse teams, research presentation, and ethics. Multifaceted feedback and assessment provided a constructive alignment with real peer-reviewed bioinformatics research. We believe that the inclusion of these transferable, interdisciplinary, and critical concepts in a bioinformatics course can help produce rounded, experienced graduates, ready for the real world and with many future options in science and society. In addition, we hope to provide some ideas and resources to facilitate such inclusion.
Gender Differences in the Perception of Selected Aspectsof Social Media as Part of Ecommerce Activities during a Pandemic
Authors: Nastišin Ľudovít , Fedorko Richard , Bačík Radovan
Published: December 2021

Objective - In the current time of pandemic crisis, social media is one of the most effective tools for ecommerce to keep in touch with customers. One of the most affected segments worldwide is undoubtedly the tourist segment. Our goal was to examine the perception of selected aspects of social media in the light of gender differences during a pandemic in the tourist segment, when these can convince or discourage the customer to buy.

Methodology/Technique - Data collection took place from the beginning of 2021 and lasted 3 months. It was an online questionnaire and focused on customers of travel agencies. A total of 723 valid responses were collected. These were analyzed for statistical significance of gender differences using SPSS software.

Findings - The results identified significant differences in perceptions between men and women in some of the areas examined. The best forms of content that work best on these platforms have been identified. Attitudes towards communication through social media for marketing purposes were also identified. These were perceived positively in order to support purchasing decisions. We also identified a great need for personalization in communication via social media in a given tourist segment.

Novelty - All findings show great implication potential for both theory and practice. The pandemic situation has changed market conditions and many of these changes will persist beyond. There is therefore a need to examine these contexts in the future. Managers in the tourism segment are able to incorporate the identified results into the way they manage their online activities and manage their social media.

Voltage Flicker Parameter Estimation Based On Improved Analytic Energy Operator And Novel K-B Mutual Convolution Window
Authors: Li yunfeng , Gao Yunpeng , Feng Yinghui , Cao Yijia , Zhu Yanqing
Published: December 2021

It is difficult to measure voltage flicker parameter accurately and in real time under a complex power grid environment, a voltage flicker envelope extraction algorithm based on multi-point differential improved analytic energy operator (IAEO) is proposed, which simplified formula for extracting flicker envelope and a novel K-B optimal mutual convolution window function is constructed. Then, the correction formula of flicker amplitude and frequency is derived based on the three-spectral line interpolation of the novel K-B optimized mutual convolution window, and the estimation algorithm of voltage flicker parameter is proposed based on the IAEO and the novel K-B mutual convolution window. Finally, a voltage-flicker-parameter-estimation platform based on virtual instrument is developed. The simulation and experimental results show that the proposed algorithm can effectively measure voltage flicker parameter under single frequency modulation, multi-frequency modulation and fundamental frequency fluctuation. In addition, it can effectively overcome harmonics, interharmonics and noise interference. Compared with the existing estimation algorithm, the flicker envelope extraction is simpler, the measurement result is more accurate, and it is easy to implement embedded.

تأتي هذه المداخلة للتعريف بالإنتاج العلمي والرياضي لأحد علماء القرن الثامن الهجري/ 14 الميلادي، لتُضاف إلى سلسلة البحوث التي تنقب عن الإسهامات العلمية والثقافية والأدبية لعلماء الحضارة العربية الاسلامية ضمن نطاق الحضارة العالمية.

في البداية نُذكر بعصر الحسن النيسابوري- النصف الأول من القرن 7ه/13م والنصف الأول من القرن 8ه/ 14م- هذا القرن يعتبر من القرون الحاضرة في تاريخ الحضارة العربية الإسلامية كفترة غنية بالأحداث السياسية، الثقافية العلمية. هذا العصر صادف فترة الحكم المغولي في دار الإسلام. ونرى كيف تحول هؤلاء الغُُزاة بعد استقرارهم في البلاد الإسلامية إلى البناء والتشييد وتشجيع الحركة الأدبية والعلمية، من مثل تكَليف هولاكو (ت. 663 ه/ 1265م) لنصير الدين الطوسي (ت. 672ه/ 1274 م) ببناء مرصد فلكي، في مرغه عام 657ه/ 1259م.

 في كنف هذه البيئة سنتحدث عن حياة ومؤلفات النيسابوري، مُركِّزين على إنتاجه الرياضياتي الموسوم ب: "الرسالة الشمسية في الحساب"

في الأخير سنحاول مقارنة هذا العمل مع بعض الأعمال المنجزة في هذا المجال من مثل: أعمال ابن البنا المُراكشي (ت. 721ه/ 1321 م) ونصير الدين الطوسي.

مكافحة الأعمال الإرهابية في القانون الاتحادي رقم 7 لسنة 2014
Authors: الجسمي نوف
Published: December 2021

نظراً لأهمية المواجهة القانونية للأعمال الإرهابية ومكافحتها، ولأنها تقع بالضرر على المجتمع ومواطنيه، فقد ضمّنت العديد من الدول تشريعاتها استراتيجية متعلقة بمكافحة الأعمال الإرهابية رغبةً منها في حماية مصالحها في الداخل والخارج، لذلك قامت دولة الإمارات العربية المتحدة بإصدار مرسوم بقانون رقم 1 لسنة 2004م بشأن مكافحة هذه الظاهرة الإرهابية، وتلاها إصدار القانون الإتحادي رقم 7 لسنة 2014م بشأن مكافحة الجرائم الإرهابية.

وهنا يثور سؤال حول ماهية الاستراتيجية التي اتبعها المشرع الاتحادي لمكافحة الأعمال الإرهابية والتي تتجلى أهميتها في موقف المشرع الاتحادي من مشكلة الإرهاب بدراسة القانون الاتحادي رقم 7 لسنة 2014م، ولمعرفة ذلك فقد تم تقسيم  الدراسة إلى ثلاثة مباحث رئيسة، يناقش المبحث الأول المسؤولية الجنائية عن الجريمة الإرهابية في القانون الاتحادي، بينما يتناول المبحث الثاني السياسة العقابية للمشرع الاتحادي في مواجهة الجريمة الإرهابية، وأخيراً يتناول المبحث الثالث القواعد الإجرائية للتصدي للجريمة الإرهابية في القانون الاتحادي.
القتل بدافع الشفقة في التشريع الإماراتي (دراسة مقارنة)
Authors: الجراح أحمد
Published: December 2021

هدف البحث إلى التعرف على مفهوم القتل بدافع الشفقة وبيان صوره، والتعرف على الاتجاهات التشريعية المقارنة وموقفها من القتل بدافع الشفقة؛ إذ إن هذا الموضوع الشفقة يثار بشدة خصوصاً بعد أن انتشر في الولايات المتحدة وفرنسا وغيرهما من الدول الغربية، فالكثيرون يكتبون وصاياهم وخاصة في حالة الموت طالبين فيها ألا يتعرضوا قرب نهاية الحياة إلى مشاكل أو مصاعب إطالة أعمارهم بالوسائل الاصطناعية. كما أن مستقبل موضوع القتل بدافع الشفقة في نطاق قانون العقوبات الاتحادي يجب أن ينظر له بعين الحذر، فالتعسف وارد إذا ما نص على حق الإنسان في الموت، وعدم إمكانية حصر الحالات التي مكن التدخل فيها لإنهاء الحياة مؤكد، كما أن توسع التشريعات المقارنة التي تقبل عدم تجريم القتل بدافع الشفقة يؤدي بلا شك إلى إهدار الحق في الحياة، ويخلق مناخاً ملائماً للتحريض على طلب الموت أو المساعدة على الانتحار.
حدود الرقابة البرلمانية على الهيئات الإدارية اللامركزية "دراسة مقارنة"
Authors: القيسي نذير
Published: December 2021

أقرَّ دستور العراق النافذ لسنة 2005 وقانون المحافظات غير المنتظمة في إقليم رقم (21) لسنة 2008 المعدل نظام اللامركزية لإدارة المحافظات غير المنتظمة في إقليم، إلا أن المشرع العراقي انتهج مسلكاً مغايراً لما سارت عليه دول العالم التي تأخذ بنظام اللامركزية الإدارية مما أثار العديد من الإشكالات القانونية.

وقد هدفت هذه الدراسة إلى تسليط الضوء على البنيان القانوني للرقابة على الهيئات الإدارية اللامركزية وبيان الإشكالية الرئيسة المتمثلة بوجود حالة من الغموض والتناقض في التشريعات الناظمة لرقابة البرلمان على الهيئات الإدارية اللامركزية.

وخلصت هذه الدراسة إلى مجموعة من النتائج أهمها أن الأسس التي اعتمدها المشرع العراقي لتطبيق نظام اللامركزية الإدارية قد شابها العديد من السلبيات والعيوب، كما أن بعض الاختصاصات التي حددها المشرع لمجلس النواب يمثل خروجاً عن المهام الأصلية للبرلمان فضلاً عن تداخل هذا الاختصاص مع اختصاص السلطة القضائية.

كما توصنا إلى بعض التوصيات أهمها ضرورة قيام المشرع العراقي بتفعيل الرقابة الإدارية للهيئات المركزية على الهيئات المحلية، مع وضع آليات محددة للرقابة البرلمانية تتلاءم مع الدور الرقابي الأساسي للبرلمان ولا تتعارض مع اختصاص الجهات الرقابية الأخرى.
Krytycznie o gatunku – Lema i Dukaja poglądy na fantastykę naukową
Authors: Przytuła Piotr
Published: December 2021

In the essay Science fiction: a hopeless case - with exceptions, Stanisław Lem spoke negatively about science fiction (but also about its authors and fans), proving its secondary nature and entanglement in market laws, pointing out the lack of reliable criticism from outside the fandom and flattering the tastes of recipients who only seek entertainment in literature. The author of Solaris included science fiction in the “lower kingdom” of literature, contrasting it with mainstream (“upper kingdom”). Thus, he symbolically strengthened the division into the fantastic “ghetto” and mainstream literature.Jacek Dukaj also spoke about science fiction in a slightly less categorical tone. In the essay Krajobraz po zwycięstwie, czyli polska fantastyka AD 2006 [Landscape after victory, or Polish fantasy AD 2006], the author of Ice noticed similar problems that Lem had seen in the past (lack of external criticism, lack of ambition, stagnation and reluctance of SF writers to go beyond plot and language patterns, flattering fashions and treating science fiction prose only as entertainment literature); however, unlike Lem, he seemed to be interested in the fate of his environment and proposed specific solutions that could raise the rank of science fiction.
Genetyka pandemii COVID-19

Błyskawiczne rozprzestrzenianie się zakażenia wirusem SARS-CoV-2 ma swoją przyczynę nie tylko w biologii tego łatwo przekazującego się zakażenia, lecz również w zwiększeniu mobilności globalnej populacji oraz szybkości transportu międzynarodowego. Z perspektywy historycznej, pandemie wirusowe występowały już w czasach nowożytnych, były spowodowane przeskokiem na człowieka wirusa z rezerwuaru zwierzęcego i również objęły setki milionów mieszkańców ziemi. Dzięki osiągnięciom diagnostyki molekularnej i nowym metodom sekwencjonowania jesteśmy świadkami bieżącej oceny stanu epidemicznego indywidualnych populacji oraz szybkiej ewolucji wirusa. Wpływ tych osiągnięć medycyny na sam przebieg pandemii pozostał umiarkowany. Największe sukcesy w jej opanowaniu odniosły izolowane geograficznie Australia i Nowa Zelandia, które po prostu zamknęły granice zewnętrzne i wprowadziły wielomiesięczne restrykcje dla obywateli. Zostały opracowane szczepionki przeciwko COVID-19, które przetestowano i zatwierdzono do zastosowania. Ich działanie ochronne przed ciężkim zachorowaniem nie budzi wątpliwości. Jednakże następna fala zakażeń COVID-19 ogarnia kolejne kraje, zmienia się jedynie struktura demograficzna chorych, którym młodszy wiek i dobre samopoczucie dawało ułudę wrodzonej odporności.

Authors: Minin Yuriy V. , Kucherenko Tetiana I. , Minina Ganna Y.
Published: December 2021

Aim: study the anatomical features of the upper respiratory tract in patients with ronchopathy of varying degrees of clinical manifestations.
Materials and methods: 60 patients with persistent snoring were under supervision. They were divided into four clinical groups depending on the degree of snoring and obstructive sleep apnea. All patients underwent clinical and instrumental examination, which included cardio-respiratory monitoring and MRI examination of the upper respiratory tract.
Results: In the comparative analysis of results of clinical studies of the upper respiratory tract of patients with and without obstructive sleeping apnea, there was a statistically significant narrowing of the retroglossal space in 45,7% and 16%, respectively. In the analysis of morphometric parameters of the upper respiratory tract in patients with sleep-disordered breathing of varying severity, there was a narrowing of the retropalatinal and retroglossal lumens of the pharynx due to the increase in the soft palate and tongue with its dislocation posteriorly. It is stated that more pronounced narrowing of the lumen of the upper respiratory tract leads to respiratory disorders during sleeping. The most severe manifestation of respiration deterioration during sleeping were observed in the narrowing of the upper respiratory tract at several levels.

Authors:   Northern (Arctic) Federal University named after M.V. Lomonosov, Plakhin Vadim A. , Khabarov Yuriy G. , Veshnyakov Viacheslav A.
Published: December 2021

Colloidal silver solutions can be used as catalysts for carrying out various chemical transformations of organic substances and solving the problems of disposal of toxic compounds, as well as antibacterial agents for combating pathogenic microflora, in the manufacture of lubricants and light-absorbing materials, coatings, sensors, conductive pastes, and high-performance electrode materials. The research purpose is to study the synthesis of colloidal silver using a solution of technical lignosulfonates (LST) as a stabilizer. Colloidal silver was synthesized as a result of the reduction-oxidation (redox) reaction of Ag(I) cations with glucose at 100 °C in the presence of lignosulfonates. The reaction was carried out in an alkaline medium, which is provided by the addition of ammonia water. Electronic spectroscopy was used to control the synthesis of colloidal silver. After the reaction, the solution turned dark brown and an intense absorption band with a maximum at 400 nm appeared on the electron spectra. The effects of reagent consumption and synthesis duration were studied. It was found that the optimal reagent consumption in the colloidal silver synthesis is as follows: 2.5–5 g glucose / g Ag, 0.3–1 g LST / g Ag, and 3–5 g NH3 / g Ag. The synthesis duration is 2–5 min. The resulting colloidal silver solution is stable for several months. Partial stratification without precipitation is observed during the solution storage. It is shown experimentally that the stratification is followed by a redistribution of colloidal silver particles. Electron spectroscopy confirmed the absence of colloidal silver particles in the upper layer. The reaction kinetics has been studied in experiments carried out under thermostatically controlled conditions at temperatures from 50 to 100 °C. The kinetic dependence is described by a first-order equation at the initial stage of the reaction, the duration of which depends on the temperature. The duration of the active part of the kinetic curves is 15–90 % of the total reaction time. The logarithm of the rate constant on the active section was proved to depend linearly on the reverse thermodynamic temperature (pair correlation coefficient is 0.9887). The activation energy was 47 kJ/mol. For citation: Plakhin V.A., Khabarov Yu.G., Veshnyakov V.A. Synthesis of Colloidal Silver Using Lignosulfonates.

The maximum value of Mg# [= 100Mg/(Mg + Fe2+ + Mn)] in chromium-bearing spinel-group minerals (Chr) in the Ultrabasic Core Zone (UCZ) of the Lyavaraka orthopyroxenite – harzburgite – dunite complex of the Serpentinite Belt in the Kola Peninsula is 54.5–67.5. Such highly magnesian compositions of spinel are associated with notable enrichments of ferric iron (Fe3+# 58–63). There are two generations of accessory Chr in the UCZ unit. The first generation occurs as inclusions in olivine that is not unusually magnesian (Mg# 90.3), and the second is closely associated with serpentine. The compositional series of Chr at Lyavaraka attains more aluminous compositions than was observed in nearby intrusive bodies. The anomalously high level of Mg in Chr, also manifest in ilmenite, is mainly a result of the high intrinsic fugacity of oxygen attained locally in the melt. A progressive buildup in H2O and increase in fO2 likely resulted from efficient vesiculation and selective loss of H2 from the Al-undepleted komatiitic magma crystallizing in a shallow setting. The chromian spinel forming in such a modified magma is virtually unzoned in Mn, and a minor quantity of Mn is also present in olivine and orthopyroxene. In contrast, zinc is strongly partitioned in the core of Chr, as it is relatively incompatible in the coexisting olivine and orthopyroxene at that stage. Zinc efficiently partitioned into the H2O-enriched melt, which crystallized as the pegmatitic orthopyroxenite near the contacts at Lyavaraka. A high potential of oxidation appears to be characteristic of all orthopyroxenite – harzburgite – dunite suites of the Serpentinite Belt formed from a primitive melt of komatiitic composition.
Distribution of sulfides and PGE minerals in the picritic and taxitic gabbro-dolerites of the Norilsk 1 intrusion
Authors: Tolstykh Nadezhda , Garcia Jonathan , Shvedov Gennadiy
Published: December 2021

Disseminated ores in the Norilsk 1 intrusion were studied to elucidate the typomorphic features of sulfides and noble metal mineralizations in picritic and taxitic (or lower olivine) gabbro-dolerites. The former are characterized by the development of a low-sulfur sulfide association (troilite, Fe-rich pentlandite, talnakhite, chalcocite, native copper) while the latter exhibits a high-sulfur association (monoclinic pyrrhotite, Ni-rich pentlandite, pyrite, heazlewoodite). The contact between these types of rocks is geochemically and mineralogically contrasting. The mineralogical and geochemical zoning directed from the roof to the base of each layer is expressed by an increase in the Cu content (and chalcopyrite) in ores, an increase in the concentration of Ni in pentlandite and S in pyrrhotite in line with a decrease of the crystallization temperature, and an increase in sulfur fugacity in the same direction. Zoning of Pd(Pt) mineralization in picritic and taxitic (olivine) gabbro-dolerites is uniform and characterized by the distribution of Pd-Sn compounds in the upper parts (together with Pd-Pb minerals in picritic rocks) and Pd-As compounds in the lower parts of the sections according to a drop in temperature. Such reverse zoning contradicts the typical mechanism of differentiation by fractional crystallization, and possibly suggests a fluid-magmatic nature. Mineralogical and geochemical features in platinum group element-Cu-Ni-bearing rocks are consistent with the idea that different stages of multi-pulse intrusions of mafic-ultramafic magmas with different compositions formed the picritic and taxitic gabbro-dolerites of the Norilsk region.

The Varzuga River on the northern shore of the White Sea is an important site for the archaeology of Russian Lapland. Here the archaeological study of this region began. The work provides a historiographical overview from the first finds in the XIX century to the excavations of 2009–2013, when two objects were examined: the fortification of the beginning of the XV century and the rural cemetery of the XIV–XVIII centuries. The reconstruction of a small rural fortress was made. We managed to find the first church of the village of the end of the XIV — beginning of the XV century. Interesting information about the late medieval burial rite has been obtained. Anthropological materials speak about the Karelian basis of the medieval population of the Terek coast. According to the results of archaeological work, it is clear that in the middle of the XIV century, a large Korela settlement with a church already existed on the site of the modern village.
S. S. Uvarov and his unrealized draft of the charter of St. Petersburg University (1819)

The article deals with an important subject, which seems to have fallen out of the field of research, which is connected with the development of a draft special charter for the St. Petersburg University in 1819–1823. This project was developed personally by S. S. Uvarov, who was then a trustee of the Saint-Petersburg educational district. The aim of the work is to reconstruct the content of this lost project, which was based on the traditions of German free science, based on the materials of its discussion in the Main Board of Schools. This episode clearly reflected the triumph of religious- conservative attitudes in the policy of the Ministry of Public Education, which prevented the implementation of S. S. Uvarov's plans to "arrange" a European-level university in the capital of the empire, combining an educational organization on the model of German universities, a special faculty structure and management, more centralized than what was provided for by the university charters of the early XIX century.

The article examines various forms and mechanisms of academic interaction that developed between the universities of the Russian Empire, namely between St. Petersburg and Helsingfors (Alexander) universities. This interaction is reflected in the correspondence of two professors-philologists: P. A. Pletnev and J. K. Grot, which served in 1840–1853 at the University of Helsingfors. The results of inter-university communication include the organization of the Russian language department at Alexander University with the participation of Russian professors and teachers, the participation of professors and students of one university in commemorative practices of another (anniversary celebrations, solemn acts), the exchange of scientific and educational literature, organized expert activities, academic migrations, although relatively few in number. An analysis of the forms of cooperation reflected in the confidential personal correspondence of representatives of the two universities reveals the similarities and differences between the two models of the university — the imperial, based the capital and the territorial university, which was the Alexander University in the Grand Duchy of Finland. The observations are based on materials from the correspondence of P. A. Pletnev with J. K. Grot, both published in the 19th century, and archival ones — from the Pletnev fund at the Institute of Russian Literature of the Russian Academy of Sciences (Pushkin House). In addition, documents of university and departmental office work were also involved. The main source under study reflects not only the details of the biographies and characters of both correspondents, but also the peculiarities of everyday academic life, university administration, professorial life, the moods of both correspondents, which change depending on the academic and political situation. The correspondence between the two professors provides an insight into the relationships and conflicts within academic corporations at St. Petersburg and Helsingfors universities. It is important that these relations and events were reflected in the source directly and synchronously with their flow.

Published: December 2021

In this article, for the first time, the distribution of well-known strategies and tactics of competitive actions by stages of the lifecycle according to the model of D. Miller and P. Friesen is carried out, which allows to provide a more accurate description of the competitive activity of an organization at different stages of its development. Tactics and strategy are closely related, and there is a need for their gradation in the context of the characteristics of the stages of the organization’s life cycle. This study is especially relevant in the period of the COVID-19 pandemic, where tactical models of competition play a special role in accordance with the selected strategies in the field of restaurant services. During the analysis of the activities of restaurant service establishments at different stages of the life cycle, certain patterns in the competitive actions of the organization were identified, which can be compared with the strategies and tactics of competition. The criteria for determining the stage of development of the organization, which determine the conduct of competitive processes, are given. Each stage of the organization’s life cycle is characterized: birth, development, maturity, flourishing, decline on the example of the restaurant services sector. It shows how organizations apply different strategies and tactics of competitive actions within each stage of the life cycle, as well as during the transition from one stage to another. The use of this article can help restaurant businesses by applying the developed matrix of tactical models of competition at various stages of the organization’s life cycle within the framework of a competitive strategy in the practical activities of the organization. Thus, the result of successful implementation of the strategy and tactical models is an increase in the number of potential guests, including permanent ones, and an increase in investment, production, sales and other opportunities.
Moving Away from Consumer Welfare in the Antitrust of Digital Platforms
Authors:   Synergy University, Kovalenko Alexander I.
Published: December 2021

This article aims to characterize the new theoretical and methodological reversal observed today in the American antitrust regulation of digital platforms. To this end, the author retrospectively describes the history of the development of the theory and methodology of antitrust regulation in the United States. The article describes the ideas of economic structuralism of the “Harvard school”. Further, the author reveals the theoretical and methodological revolution associated with the theory of prices; describes the fundamental differences between the “Harvard” and “Chicago” schools in terms of assessing the relationship between market structure and the intensity of competition. The article reveals the formation of the doctrine of consumer welfare as the dominant one in antitrust regulation. The consequences of the application of the doctrine of consumer welfare in antitrust regulation are described: the narrowness of ideas about barriers to entry, public welfare; breadth of understanding of competitive forces; ignoring the structural and sectoral characteristics of competition; absolutization of indicators of consumer prices and output volumes. The author gives a negative assessment of the effectiveness of the application of the doctrine of consumer welfare in the antitrust regulation of digital platforms. The paper explains how the focus on consumer welfare has been used by digital platforms to generate gigantic market power. In this context, a criticism of the ideas of the Chicago School in relation to digital markets is presented. Reanimation of ideas and methods of economic structuralism in decision-making within the framework of antimonopoly regulation of monopolistic activities of digital platforms is argued.
