Published: March 2022

The article considers the process of choosing an effective option of innovation and investment economic development, which involves assessing the possibility of innovative development, intensification of investment activities and the effectiveness of potential alternatives and directly forming an appropriate option for using innovation and investment potential of economic development. There are three main components of assessing the possibility of innovative development, such as: resource, which indicates the existence of conditions, the level of innovative resources to ensure innovative development; technological, which reflects the level of technological renewal of production through the introduction of new technological processes and development of production of new products using the principles of rational nature management and market, which highlights the impact of the enterprise on the economy through the sale and saturation of the market with innovative products. Assessment of the possibility of intensification of investment activity, which is determined on the basis of two conceptual approaches: resource characteristics, when investment potential is defined as a set of investment resources (material, financial and intellectual) and effective, the assessment of potential taking into account actual parameters of investment processes. A matrix of selection of an effective variant of innovation and investment potential of economic development is proposed, which allows predicting the use of this potential on the basis of an objective analysis of external and internal environmental factors. In general, the development of innovation and investment potential can take place in four directions: excellent (positive) – due to strengths and external opportunities, the level of innovation and investment potential is high; optimal - with the possibility of forming the development of innovation and investment potential; adaptive - with insignificant possibility of potential development under the condition of its adaptation to environmental threats and negative – there are no opportunities for potential development.

Published: March 2022

Изучение суицидологической ситуации в регионе – важный этап исследований, позволяющий оценить уровень самоубийств, выделить факторы и группы риска, определять возможные направления совершенствования мер профилактики и оценивать их эффективность. В условиях малых территорий проведение подобной работы сопряжено с рядом особенностей, среди которых, по мнению авторов, наиболее значимы: 1. Большой разброс значений уровня суицидальной смертности (рассчитываемого на 100000 населения) в различные периоды (годы). 2. Сложности с учётом суицидальных попыток (отсутствие инструмента). 3. Ограничение возможности корректной оценки факторов риска (алкоголь, безработица, уровень жизни и др. 4. Ограничение доступности помощи специалистов в области психического здоровья. Цель исследования: анализ суицидальной активности населения в малой территории. Материал и методы: для получения более объективной картины, авторами использован динамический подход с оценкой ключевых показателей за длительный период (в работе – 2010-2020 гг.). В качестве малой территории выбран г. Ялуторовск (40 тыс. населения) и район (14 тыс. населения). В настоящем сообщении I даётся анализ летальных суицидов. Результаты: в ходе исследования было показано, что г. Ялуторовск и район – культурно-историческая жемчужина юга Тюменской области, относится к территориям с динамично снижающимся уровнем суицидальной активности, и в последние годы демонстрирует показатели ниже среднероссийских (ниже 10 случаев на 100000 населения). Тем не менее, в ходе реализации работы было выявлено значительное «омоложение» женских суицидов как в городской, так и сельской популяции, более частое, чем по стране, применение огнестрельного оружия, постмортальное выявление превышающего уровня алкогольной составляющей при отмеченных «особенностях» наркологического учёта, что требует более глубокого анализа ситуации в целом. В заключении авторами делается вывод о достаточной эффективности и приемлемости динамического подхода для анализа суицидологической ситуации в малой территории. Полученные результаты могут иметь большое значение для практического здравоохранения и разработки дифференцированных мер профилактики.
Скулшутинг: убийство и постгомицидное самоубийство как трансгрессивный акт
Authors: Узлов Н.Д. , Семенова М.Н.
Published: March 2022

В статье предпринята попытка осмысления явления скулшутинга ─ вооружённых нападений учащихся на образовательные учреждения через феномен трансгрессии ─ одного из ключевых понятий в философии постмодернизма. Показано, что убийство трансгрессивно по своей сущности и многообразию его форм. Скулшутинг представляется деструктивным вариантом трансгрессивного акта (в трактовке Жоржа Батая) как агрессивный выход за пределы морально-нравственных, правовых и религиозных границ. Анализируется конструкт Предела (шестая заповедь Декалога «не убий») как трактовка особого ценностно-смыслового образования. Поведение шутеров рассматривается через призму злокачественного нарциссизма. В качестве иллюстраций его проявления проводится содержательный анализ высказываний массовых убийц, изложенных ими в так называемых «манифестах» в форме спекулятивных ложно-философских идей «равенства с Богом» и «смерти Бога», в качестве обоснования своих преступных намерений. Даётся трактовка постгомицидных самоубийств скулшутеров с позиций постмодернистского дискурса о смерти. Подчеркивается символический и коммуникативный характер акта совершенного насилия и суицида, требующего прочтения как текста. Указывается на необходимость формирования соответствующих внутренних барьеров к Пределу, не допускающих потенциальной возможности совершения убийств – как одно из главных условий превенций таких преступлений.

Самоубийства в трагедиях У. Шекспира
Authors: Малышева В.А. , Голенков А.В.
Published: March 2022

Самоубийства встречаются у героев многих литературных произведений, их описание многоаспектно и представляет исследовательский интерес. Цель работы – выделить случаи самоубийств (включая постгомицидные самоубийства) в трагедиях У. Шекспира и провести их сравнительный анализ с данными научных публикаций. Материалы и методы. Проанализировано восемь трагедий всемирно известного драматурга с 14 эпизодами самоубийств, опубликованных на русском языке. Результаты. Самоубийства совершили восемь мужчин и шесть женщин. Чаще всего (50%) в качестве орудий использовались колюще-режущие предметы, далее следовала преднамеренная смерть от укуса змей (два случая), проглатывание горячих углей, отравление, утопление; в двух случаях из содержания трагедии было известно, что герои совершили самоубийства, но способ ухода из жизни не описывался. В большинстве случаев мотивом самоубийств являлось избегание «унижения и стыда» (военные после поражения в битвах, утрата своего особого высокого положения), самонаказание за совершённые преступления (убийства жены и сестры при постгомицидных самоубийствах). У двух героев уход из жизни был обусловлен смертью любимого (близкого) человека (острая кризисная реакция), ещё у одного – мизантропией (и ненавистью к самому себе) с очевидными личностными девиациями. Вероятное психотическое расстройство встречалось в одном случае. Заключение. По драматическим произведениям У. Шекспира можно изучать многие базисные аспекты суицидологии и аддиктологии. Реальность их описания одним из лучших писателей (поэтом) мира послужила в ряде случаев основой для создания эпонимов («синдром Отелло», «синдром Офелии», «эффект Ромео и Джульетты», «эффект леди Макбет»), используемых в современной медицине и психологии.

Authors: Etrata, Jr. Antonio , Bandiling Von Jarelle , Peralta Kurt , Relucio Rean Marvee
Published: March 2022

The advancement in technology and the changes in consumer behavior have led to the practice of purchasing items online and have recently received a lot of attention. Many consumers prefer to purchase online, while others remain hesitant. Information has traveled faster and become more available on the Internet as social media platforms such as Facebook, Twitter, and Instagram have increased in popularity in today's culture. However, not all information found online is reliable and credible. Consumers need to check the veracity of the information that is deemed useful in the decision-making process. This research aims to evaluate the effects of reliable and credible information on shopper trust and shopper trust to shopper’s buying behavior. A total of 258 respondents were chosen using purposive sampling. The researchers used principal component analysis (PCA), where a set of data is summarized or "reduced" to a smaller set of features or variables. After applying PCA to obtain the questionnaire variables, the researchers used multiple regression analysis to consider the impact of independent variables on the dependent variables. The results show that reliable information and credible information affect shopper trust. Moreover, it was also confirmed in the analysis that shopper trust influences shopper’s buying behavior. The results of the study will benefit business owners and marketing practitioners in crafting their communication materials and messages and consumers who heavily rely on information as part of their decision-making process.

Authors: Almadin Harold , Antiporda Jose Miguel Q. , Suin Kristine April S.
Published: March 2022

Using time-series data from 1989 to 2018, this study examines the determinants of public education expenditure in the Philippines. Following Wagner’s law, this paper investigated the relationship of gross domestic product per capita, unemployment rate, urban population growth, and lagged public education expenditure to public education expenditure. The ordinary least squares (OLS) method was used to determine the significance of the variables, and statistical tests were conducted to measure the overall significance of the model. The findings show that gross domestic product per capita and lagged public education expenditure were positively significant determinants contributing to the Philippines' growth of public education expenditure. On the other hand, the unemployment rate and urbanization growth were insignificant and did not contribute to the increase in expenditure. The results also provided strong evidence on the relationship between GDP per capita and public education expenditure, supporting Wagner’s law in the Philippine context. Finally, this study recommends that policymakers review budget allocation and utilization to achieve wider education accessibility and better quality of education in the Philippines.

OPTIMASI PRODUKSI ECOPRINT FABRIC DENGAN TEKNIK ROTARY PRINTING
Authors: Cahyana Agung , Afrizal Afrizal
Published: March 2022

Abstract Ecoprint is a process of transferring colors and shapes to the fabric through direct contact between the leaves and the fabric. Ecoprint technique is an advancement technique in ecofashion that produces environmentally friendly fashion products. The coloring that are often used by the techniques are iron blanket technique and pounding technique. Furthermore, another technique used for coloring ecoprint fabric is using the leaves as ecoprint stamps. It works by coloring the leaf sheet with natural or synthetic dye and followed by adhering the leaf onto the fabric. By pressing the leaves that have been covered in dye, a leaf motif with its tissue will appear on the fabric. The ecoprint stamp technique is easier than other techniques. In the implementation, this technique is still considered taking a long time in the process that an eco-rotary printing technique needs to be developed. Its technique is expected to solve problems that ecoprint stamp techniques have. The engineering of eco rotary print tool as a medium on cap rotary printing technique is resulting 2 prototypes. i.e., 2 roll model, and 3 roll model. The eco-rotary printing method is inspired by a motif roll paint that are able to give color motif on the walls in a relatively fast time. Thus, the leaves are affixed to the roll combined with natural dyes to create a leaf motif on the surface of the fabric. The test results from the two prototypes of the tool are presented. The 3 roll model gives the result of leaf motif color on the fabric with better quality than the 2 roll model. This makes production more effective and efficient in terms of the time of the production process. And, finally, the results of this study are very possible to be utilized in the production of large-scale ecoprint fabric. Key word : Ecoprint, Ecofashion, Eco Rotary Print

NEW DIGITAL COMPETENCE FOR SCIENCE TECHNOLOGY AND ENGINEERING EDUCATION
Authors: Kordigel Aberšek Metka , Aberšek Boris
Published: March 2022

In the years 2019-2021 a significant step was made in terms of distance learning, which would have otherwise, in normal circumstances, taken several years. While the solutions applied were the best in the given situation, the question arises of what these solutions imply in terms of long-term, systematic changes. The presented research touches upon three key areas that characterize today’s schools: motivation, atmosphere, and competences of teachers and teacher-training students. The starting point of this research is the premise that the pre-crisis digital competences are simply not good enough for today's situation, or for the near future. Research results show that such fast-tracked changes and the transition to distance education have led to a significant decrease in the motivation of both, teachers and students, that the general atmosphere has worsened, and that there is a significant decrease in competences to be perceived, especially with regard to social and communication competences. The research shows also that neither teachers nor students are sufficiently qualified to work in the society of the future, in society 5.0. What is needed are actual, real changes in the field of digital literacy and digital competences, also indicated in this research.

AN EXPLORATION ON CONCEPT TEACHING KNOWLEDGE OF BIOLOGY TEACHERS IN LOWER-SECONDARY SCHOOLS
Authors: Li Mingyu
Published: March 2022

The topic ‘photosynthesis’ contains many intangible and abstract scientific concepts, regarding which students hold many preconceptions. Conceptual learning is a process of co-creation and flow that requires the teachers’ higher educational level on conceptual teaching. The present research considers photosynthesis as an example. Results of Ball's 2008 research on teachers' content knowledge for teaching served as the theoretical framework. In total, 30 biology teachers from 11 lower-middle schools in a medium-sized city in China were selected as the research objects. The conceptual learning achievements of 1442 students taught by those teachers were used as a yardstick, and two sets of self-designed questionnaires were used to demonstrate, describe, and discuss these elements and their current state in the teachers' mind and determine influencing factors. According to the results, except for the knowledge of concept and student element, all the other three elements attained the passing level. Specifically, the level of common concept knowledge was relatively high, but this element had not attained the perfect level. A scope for improvement was observed for the other three conceptual knowledge elements. No significant difference in the knowledge elements level was observed among the teachers from different schools.

This research is conducted to identify the scientific conceptual cognition of ecosystem and the corresponding alternative conceptions by lower-secondary school students in Taiwan. Concept mapping, interviewing, and two-tier diagnostic test cannot make explicit reasoning pathways that students may use. Therefore, its purpose is to develop, validate, and utilize a three-tier multiple-choice diagnostic instrument for the ecosystem concept (TDIEC). The instrument can assist teachers in analyzing their students’ reasoning. This does not only distinguish alternative conceptions from lack of knowledge but also determines the percentages of false positives and false negatives. One hundred and six students were tested with this instrument in Taiwan. The data analysis reveals common alternative conceptions shared by students, indicating that 35.59% of the samples had inaccurate conceptualizations of ecosystems. Common alternative conceptions of ecosystems include the following: (i) Only biological components constitute an ecosystem; (ii) The Venus flytrap and pitcher plants are preys; (iii) Competition is synonymous to predation; (iv) Ecological balance refers to the sustainable circulation of energy and matter in the environment; and (v) The simpler the species, the more stable the ecosystem. It concludes with the interpretation of the results, suggestions for the application of the TDIEC, and correct alternative conceptions in Ecology classes.

Chemotherapy is the primary treatment option for acute myeloid leukemia (AML), but leukemic stem cells (LSC) can survive chemotherapy for disease recurrence and refractory. Here, we found that AML cells obtained from relapsed patients had increased autophagy levels than de novo AML cells. Furthermore, doxorubicin (DOX) treatment stimulated autophagy in LSC by repressing the mTOR pathway, and pharmaceutical inhibition of autophagy rendered chemoresistant LSC sensitive to DOX treatment in MLL-AF9 induced murine AML. Moreover, we developed a self-assembled leucine polymer, which activated mTOR to inhibit autophagy in AML cells by releasing leucine. The leucine polymer loaded DOX (Leu-DOX) induced much less autophagy but more robust apoptosis in AML cells than the DOX treatment. Notably, the leucine polymer and Leu-DOX were specifically taken up by AML cells and LSC but not by normal hematopoietic cells and hematopoietic stem/progenitor cells in the bone marrow. Consequently, Leu-DOX efficiently reduced LSC and prolonged the survival of AML mice, with more limited myeloablation and tissue damage side effects than DOX treatment. Overall, we proposed that the newly developed Leu-DOX is an effective autophagy inhibitor and an ideal drug to efficiently eliminate LSC, thus serving as a revolutionary strategy to enhance the chemotherapy efficacy in AML.

Introducción. Las políticas de accesibilidad universal vinculadas a las personas con discapacidad en el Ecuador instituyen un tema de características complejas, el detrimento de la aplicación de las normas de accesibilidad universal como táctica de inclusión de las personas con discapacidad a nivel nacional, produce que los servicios que se ofrezcan sean endebles y condicionados. Objetivo. Implementar una estrategia de desarrollo inclusivo fundamentado en el entorno y en la comunidad. Metodología. Se empleó una investigación bibliográfica con enfoque cualitativo, en donde se seleccionó como muestra a tres ciudades del país cuyos espacios tienen características de riesgos y exclusión. Resultados. Entre los resultados obtenidos se encuentra que existe un amplio margen de desconocimiento de la terminología relacionada a entornos inclusivos como la accesibilidad universal. Conclusión. Se concluyó que, a pesar de contar con la normativa de accesibilidad universal, existen varios factores que imposibilitan su aplicación, produciéndose ciudades discapacitantes en todo el país.

Introducción. Conocer si la ciudad de Guayaquil ha pasado la barrera de ser una ciudad digital a ciudad inteligente, pero no sólo conocer lo anteriormente expresado, sino también si ocurrió, cuando fue que sucedió y como se lo está haciendo, analizar sus perspectivas y desafíos, todo esto con el propósito de aportar nuevas ideas, críticas y conclusiones que aporten al mejoramiento y desarrollo de la ciudad. Objetivo. Analizar si la ciudad de Guayaquil es ciudad digital o ciudad inteligente. Metodología. La metodología aplicada en la presente investigación es de diseño bibliográfico con características de tipo documental. Resultados. Una ciudad inteligente debe ser una ciudad que otorga la facilidad y conexión a internet a sus ciudadanos, sino que además sea capaz de mejorar la calidad de vida de la población, cuidar el medio ambiente, reducir la desigualdad social, poseer nervios digitales que estén en constante reflejo a respuestas inteligentes de sus ciudadanos, una ciudad sostenible en el tiempo, eficiente en los servicios urbanos y con la capacidad de monitorear y mejorar continuamente aprovechando la tecnología, en especial el internet y sus redes de datos. Conclusión. A pesar que el Municipio está desarrollando más de 120 programas y proyectos para la ciudad, estos al parecer no son lo suficiente, primero una consultoría, luego desarrolla programas y proyectos como parte de una estrategia y después las va ejecutando o implementando poco a poco, donde los cambios tecnológicos son tan acelerados que dejan en poco tiempo sin efecto algún programa terminado incluso propuesto; en este sentido, se requiere el apoyo de los propios ciudadanos desde plataformas que inviten o incentiven la participación de forma proactiva, rápida casi que instantánea o inmediata, sin dejar aislado o desconectado algún sitio de la ciudad o grupo social.

Introducción. La humanidad ha ido cambiando y en las últimas décadas éste cambio ha sido de manera acelerada, es por ello que la educación siendo una de las actividades del quehacer humano también ha ido evolucionando a través de los tiempos, de acuerdo a las condiciones de la humanidad y a aquellos pensadores y los luchadores incansables que no conformes, buscan el renovar el hacer educativo que permita una mejor forma de aprender y de enseñar. Objetivo. Determinar de qué manera la educación virtual permite desarrollar la calidad académica en las carreras de las Licenciaturas en la Facultad de Ciencias Administrativas. Metodología. Se utilizó una metodología no experimental con una muestra conformada por 1327 participantes entre docentes y estudiantes de las diferentes carreras de la Facultad de Ciencias Administrativas de la Universidad de Guayaquil. Resultados. Se evidenció la curva de aprendizaje que debieron superar los docentes y estudiantes, la intermitencia del servicio de internet y las caídas del sistema educativo de la Universidad, así como la necesidad de reforzar vacíos cognitivos, políticas y procedimientos en esta nueva modalidad online. Conclusión. La calidad educativa se vio afectada por el modelo educativo ya que el proceso curricular sufrió profundas modificaciones, sobre todo en las carreras que requerían de un mayor componente práctico; y por la infraestructura tecnológica que no logró satisfacer la demanda tanto en soporte técnico online como en el uso adecuado de todo el entorno virtual.
