Published: March 2022

Purpose: Even when price war has seen massive interest among scholars, it is still unclear how it affects sales performance. This study examined the relationship between price war and sales performance among carbonated drink manufacturers in Uganda: a case of Century Bottling Company Limited.
Methodology: Mixed methods design was used in this study. The population comprised of 210 employee managers and outlet managers. With the aid of Krejie and Morgan (1970)’s table, a sample size of 169 respondents was selected. Questionnaire was used to collect primary data in line with the positivism design and obtained a response rate of 55.0%. Pilot testing however preceded the final survey and we were able to check the relevancy of the instruments which was confirmed through the validity and reliability statistics that we achieved. Zero-order Pearson correlation was used to test the hypotheses.
Findings: The study results showed a strong positive and significant relationship between promotional pricing and sales performance (r = .522, p= 0.000). Also Penetration pricing was found to have a moderate positive and significant association with sales performance(r = .369, p= 0.000). Last but not least, the study confirmed existence of a strong positive and significant relationship between Oligopoly pricing and sales performance at Century Bottling Company Limited (r = .573, p= 0.000).
Recommendations: The study recommends that century bottling company limited consider the actual situations of different manufacturers when implementing its promotional strategies in order not to suffocate them, increase the number of sales outlets to ensure increased trades and selling, since it enables the company to access many customers and also to revisit its pricing strategy where customers like low-priced commodities and offer customer discount features according to different selling contexts.

RESUMO
Objetivo: Descrição do passo a passo de um caso clínico no qual foi empregado a técnica "Yonsei Point" para tratamento do sorriso gengival. Utilizou-se esta técnica por tratar-se de uma metodologia indicada para para redução da diferentes tipos de sorriso gengival, que utiliza apenas um ponto de cada lado da face, minimizando o risco de intercorrências de assimetrias, com custo reduzido e de fácil reprodução.
Métodos: Uma paciente do sexo feminino com 6,0 mm de exposição gengival durante o sorriso foi tratada com a utilização da toxina botulínica do tipo A (TBA) aplicada no "Yonsei Point". O "Yonsei Point" é definido com base nos três músculos (levantador do lábio superior (LLS), levantador do lábio superior e asa do nariz (LLSAN) e o zigomático menor (ZMi)) que convergem na área lateral à asa do nariz. Os três vetores destes músculos passam perto de uma região triangular formada por três pontos de referência na superfície. O centro deste triângulo, foi denominado ‘‘Yonsei Point’’. E, foi sugerido como um ponto apropriado de injeção de toxina botulínica do tipo A para correção de sorriso gengival. Para acompanhamento do caso, realizou-se um protocolo de fotos do caso antes da aplicação da TBA e após 15 dias, e a mensuração da distância entre a borda inferior do lábio superior e a margem gengival cervical dos dentes incisivos centrais superiores foi realizada nestes tempos operatórios. Após 15 dias da aplicação da TBA houve redução do sorriso gengival de 6mm para 3 mm na região do incisivo central.
Conclusão: A técnica para TBA aplicada no “Yonsei Point” no presente caso clinico mostrou-se segura, pouco invasiva, indolor, eficiente, e de fácil replicação, e reversível para o tratamento do sorriso gengival.

Published: March 2022

Prediction provides discipline and pragmatic importance to empirical research. The design with the predictive probability approach provides an excellent alternative for conducting multi-stage phase II trials; it is efficient and flexible and possesses desirable statistical properties. . In this paper we consider the Bayesian predictive procedures within the experimental design, for this, we define indices of satisfaction related to a test as a decreasing function of the p-value and satisfaction is higher than the null hypothesis is rejected wider. This design possesses good frequentist properties and allows early termination of the trial. We treated our applications by simulation and real data in experimental planning and sequential designs with binary outcomes.

This article is about a new round of the global crisis in higher education, caused by the COVID-19 pandemic.The purpose of the research is to conduct a systematic analysis of modern foreign literature on neoliberalismin the educational sphere and to identify the factors of influence of neoliberal concepts on the sphere of higher education during a pandemic.The methodology of this study was a systematic analysis of foreign scientific research literature devoted to the issues of neoliberalism, axiological problems of higher education and globalization. Were studied 20sources, including the work of leading foreign scientists-philosophers M. Apple, A. Giroud, S. McCloskey and others. The works selected for the study cover the time period from 2000 to the present day.Originality / value of the research. In the course of the analysis of the literature, the factors that influenced the quality and eff ectiveness of higher education are considered, and the prospects for postformeducation in the future are presented. Separately considered is such a direction as neoliberalism, which is the ideology of globalization, the global agenda. The opinion is substantiated that the pandemic did not create problems in the field of higher education, but only exacerbated those that already existed. The article provides an overview of the opinions of foreign scientists, presents their strategies for overcoming the global higher education crisis associated with both the pandemic and the neoliberal (market) approach to education.Findings. The neoliberal model of education, based on fi erce competition, individualism and free trade, failed in the era of the pandemic. It seems that the future prospects for the development of higher education in the world will be revised towards reducing the influence of neoliberalism and the market, strengthening state control and financing in this area, humanizing, humanitarianization, fundamentalizing and greening the sphere of higher education.
Choroidal caverns in a patient with glaucoma (case study)
Authors: Kurysheva N. I. , Pererva O. A. , Kim V. Yu. , Kim V. E. 
Published: March 2022

The article describes a clinical case of the formation of a choroidal cavern (CC) in a patient with glaucoma. CC are associated with degenerative diseases of the retina, which is likely associated with dysfunction of the choriocapillaries and impaired retinal supply. Most often, СС are the outcome of pachychoroidal conditions and age-related macular degeneration. Patient D., 63 years old, with previously diagnosed primary open-angled glaucoma in the right eye, complained of a gradual decrease in visual acuity in that eye for several years. According to the examination, the cause of vision acuity decrease was determined as partial atrophy of the retinal layers associated with CC in the superior nasal part of the perifovea and fovea. Presumably, based on signs of a pachychoroidal state in both eyes of the patient, the formed CC is the outcome of chronic central serous chorioretinopathy: focal thickening of the choroid, vasodilatation of the Haller's layer, thinning of the choriocapillaris layer, the presence of pachychoroidal pigment epitheliopathy in the left eye. CC is the marker of choriocapillary blood flow deficiency, which is an unfavorable prognostic factor for the development of glaucoma — proved by glaucoma optic neuropathy being more advanced in the eye with CC compared to the contralateral eye.
Pluton Exhumation in the Precordillera of Northern Chile (17.8°–24.2°S): Implications for the Formation, Enrichment, and Preservation of Porphyry Copper Deposits

Abstract
Hypogene mineralization in porphyry Cu deposits is typically associated with crustal thickening and rapid exhumation, whereas supergene enrichment requires slow exhumation to allow sufficient time for leaching and downward transport of Cu before it is lost to surface erosion. Therefore, spatial and temporal patterns of exhumation within a metallogenic belt can highlight favorable locations for hypogene mineralization, supergene enrichment, and preservation. Here, we determine average pluton exhumation rates along an ~730-km segment of the middle Eocene-early Oligocene metallogenic belt in northern Chile (17.8°–24.2°S). By combining zircon U-Pb geochronology with Al-in-hornblende geobarometry, we pinpoint the time and depth at which each pluton was emplaced and use the age of overlying cover units or supergene minerals to date its arrival at the surface (or near-surface) environment.
Uranium-lead zircon ages for 49 samples from plutons and porphyries range from Carboniferous to Eocene (~314–35 Ma). Al-in-hornblende emplacement depths for 19 plutons are ~4–7 km, with one Carboniferous pluton emplaced at ~12 km. Two phases of net exhumation are identified: early Permian-Middle Triassic and middle Eocene-late Oligocene, with an intervening period of net burial. The highest exhumation rates (&gt;0.30 km/m.y.) derive from the second phase, coeval with the Incaic orogeny and the main phase of hypogene mineralization. Present-day preservation of plutons and porphyry Cu deposits required low post-Oligocene average exhumation rates of &lt;~0.01 km/m.y.—favorable for the development of many world-class supergene blankets. However, spatial variability in exhumation and burial across the belt led to poor conditions for supergene development locally: enrichment was hampered in some places by rapid exhumation after hypogene mineralization (e.g., ≥~4 km at El Abra), by burial beneath significant cover (e.g., Ministro Hales, Queen Elizabeth), or, in the Inti region of northernmost Chile, by a combination of the two.

The purpose of this scientific article is to show what competitor data analytics can do with machine learning and neural networks. In this study, we analyzed data on potential partners of the Department of Defense Office of Hearings and Appeals (DOHA) of the USA and obtained a trained algorithm that can help in making decisions based on keywords, which can minimize reputational risks. The published dataset of the Department of Defense Office of Hearings and Appeals (DOHA) of the USA was selected for analysis of the initial data, which displayed the results of the screening of potential partners along with a text justification. This is the reason why we used Recurrent Neural Network (RNN) instead of Convolutional Neural Network (CNN). Neural networks are a very important part of machine learning. As a result, we have developed a trained machine learning model for recommending the best partners, that is, more proven partners, both professional and reputable. In addition, the developed machine learning model does not allow working with an organization of bad partners who could act in bad faith and carry reputational risks.
Цель этой научной статьи показать, на что способна конкурентная разведка и анализ данных с помощью машинного обучения и нейронных сетей. В данном исследовании мы проанализировали данные о потенциальных партнерах Управления слушаний и апелляций Министерства обороны США (ДОХА) и получили обученный алгоритм, который может помочь в принятии решений на основе ключевых слов и который позволяет минимизировать репутационные риски. В качестве анализа исходных данных был выбран опубликованный набор данных Управления слушаний и апелляций Министерства обороны США (ДОХА), в котором наряду с текстовым обоснованиембыли отображены результаты скрининга потенциальных партнеров. Именно по этой причине мы использовали Рекуррентную нейронную сеть (RNN) вместо Сверточной нейронной сети (CNN). Нейронные сети -очень важная часть машинного обучения. В результате мы разработали обученную модель машинного обучения для рекомендации лучших партнеров, то есть более проверенных партнеров, как профессиональных, так и авторитетных. Кроме того, разработанная модель машинного обучения не позволяет работать организациям с неблагоприятными партнерами, которые могут действовать недобросовестно и нести репутационные риски.

Производительность многих организаций зависит от их способности эффективно использовать свои системы ИТ-услуг. Это подразумевает необходимость оптимизации отношений между поставщиком ИТ-услуг и сотрудниками организации. Для управления услугами используются так называемые ITSM-системы. Но выбрать из существующих или разработать новую систему —это только «верхушка айсберга». Успешно внедрить систему и сделать так, чтобы ейпользовались —однаиз ключевых задач и важнейшее условиежизни самой системы.В данном исследовании показано, как процесс внедрения системы ИТ-услуг «Asista» одной из аутсорсинговых компаний Казахстана анализируется и модернизируется на основе расчетов эффективности. Расчеты произведены посредством применения методик бережливого производства.
The performance of many organizations depends on their ability to effectively use their IT service systems. This implies the need to optimize the relationship between the IT service provider and the people in the organization. The so-called ITSM systems are used to manage the services. But choosing from the existing ones or developing a new system is only the ―tip of the iceberg‖. Successfully implementing such a system and making sure that it is used effectively is one of the key tasks and living conditions of the system itself.This study focuses on the analysis and modernization of the ―IT services system of Asista‖, one of the outsourcing companies in Kazakhstan, based on efficiency calculations made using lean production techniques.
