THE ECONOMIC SYSTEM OF SOCIETY, CULTURE, FASHION: CATEGORICAL SUBORDINATION-ONTOLOGICAL ANALYSIS
Authors: SERHIYEVICH T.
Published: August 2021

The article examines the relationship of such phenomena as the economic system of society, culture and fashion. Culture is considered as a factor in the formation of socio-economic institutions of social systems. The increasing complexity of relations of modern society determines the relevance of the categorical refinement of phenomena and processes that are not purely economic factors. One of those is the phenomenon of fashion. If the interrelation of culture and fashion is obvious, since in scientific literature fashion is considered primarily as an aesthetic, culturological, socio-psychological phenomenon, then the conditions of trans-economy (J. Baudrillard) give rise to the need for a theoretical understanding of the fashion phenomenon and the place of its real-ontological forms in development economic system of modern society.

For any organization, the most important challenge is to retain a talented workforce. In order to retain a talented workforce, it is very important to identify factors that affect the intention of employees to leave. Thus, this study examines the effect of work-related attitudes on turnover intention in terms of academic staff context. 334 academic staff were selected as a sample using a stratified random sampling technique. The study was an explanatory design and the required data was collected through adopted questionnaires from prior studies. The obtained data were analyzed using descriptive and inferential statistics. To do so the statistical packaging for social science (SPSS) version 20 was utilized. The descriptive result indicates that the participant’s level of work-related attitudes was low whereas their level of turnover intention was high. Moreover, the results obtained through T-test and ANOVA showed that there were significant differences in the level of turnover intention based on selected demographics and thus have a varying effect on turnover intention. According to the multiple regression results, the dominant predictor of turnover intention was affective commitment and the insignificant predictor was continuance commitment.
Control Yourself! Examining the Dimensions of Eudaimonic Psychological Well-Being as Related to Locus of Control Using Structural Equation Modeling
Authors: Hough Tionna M , Labansat Heather A , Moore Tyler Forest , Wallace Rene , Higgins Kristina
Published: August 2021

Current literature on the relationship between locus of control (LOC) and psychological well-being (PWB) consistently demonstrates that individuals with an internal LOC generally report experiencing greater psychological well-being than externally-oriented individuals. However, there is minimal depth of understanding regarding the specific dynamics of this well-established relationship. The aims of the present quantitative study were (a) to replicate and provide support for the existing knowledge on the relationship between these two factors and (b) to use a structural equation model (SEM) to further explore the relationship between LOC and the six dimensions in Ryff’s model of eudaimonic PWB, which are combined to assess one’s psychological welfare. Using cross-sectional survey methodology, 267 adult participants were recruited through convenience and snowball sampling to anonymously complete a series of questionnaires online. A Pearson r bivariate correlation analysis examining the relationship between PWB and LOC revealed a significant negative correlation between the two constructs (r = -.280, p = .001). This finding replicates previous research, where individuals with an internal LOC reported experiencing significantly greater PWB, while individuals with an external LOC reported significantly less PWB. In order to further examine how the six factors of PWB (self-acceptance, positive relationships, autonomy, environmental mastery, purpose in life, and personal growth) relate to LOC, a SEM was performed. Although all six dimensions of PWB show significant negative correlations with LOC, environmental mastery, self-acceptance, and purpose in life were the most impactful on the relationship between these two constructs, as they were shown to have higher significance in the SEM. Considering the SEM suggests that environmental mastery, self-acceptance, and purpose in life are the most weighted factors of PWB’s correlation to LOC, possible interventions on these factors in a clinical or applied setting may see improvement in the relationship between PWB and LOC.

Authors: Nakazato Gerson , Favaro Wagner J , Duran Nelson
Published: August 2021

Unfortunately, Coronavirus disease 2019 (COVID-19) remains a significant public health issue worldwide, mainly in the USA, India and Brazil. The 2nd wave of COVID-19 has reached India first. The country has been making great effort to stabilize its current condition but, unfortunately, mucormycosis infection (or black fungus) associated with COVID-19 has emerged as another threat to the country and, most likely, to Brazil. It may have happened due to excessive glucocorticoid using, since the widespread administration of this drug can lead to secondary fungal infections. Mucormycosis is generated by a group of molds called mucormycetes; it is a rare, although likely fatal, contamination when patients are not properly treated. The concerning factor lies on the fact that the high COVID-19 incidence recorded in the first wave of it has increased even faster in its second wave in India; there have been some concerning cases in Brazil, as well. The current overview addresses the current therapies used to treat mucormycosis worldwide, as well as potential and new drugs for such a specific treatment. Anti-mucormycosis adjuvants and nanomaterials are the most interesting alternatives to treat patients with post-COVID-19 mucormycosis.

Роль интерференции в имплицитном усвоении последовательностей Струп-стимулов
Authors: Бурмистров Сергей Н. , Агафонов Андрей Ю. , Фомичева Арина Д. , Шилов Юрий Е.
Published: August 2021

Введение. Феномен интерференции позволяет выявлять существенные характеристики процесса формирования нового знания. Новизна данного исследования заключается в использовании эффекта интерференции для диссоциации эксплицитного и имплицитного научения. Проверялось предположение о том, что эффект интерференции, возникающий при реагировании на Струп-стимулы, снижает продуктивность приобретения эксплицитного знания последовательности, но не оказывает значимого влияния на имплицитное усвоение последовательности.

Методы. В исследовании приняли участие 80 человек (средний возраст 22,7 лет). В эксперименте использовались задачи «the serial reaction time task», в которых требуется быстро и точно реагировать на последовательно предъявляемые стимулы. Одним испытуемым (n = 40) предъявлялись названия цветов, написанные шрифтом конгруэнтного (соответствующего) цвета, другим испытуемым (n = 40) демонстрировались названия цветов, написанные шрифтом неконгруэнтного (несоответствующего) цвета (Струп-стимулы). Требовалось, не читая слова, реагировать на цвет шрифта, которым оно написано. Для выявления эксплицитного знания последовательности использовался тест узнавания фрагментов последовательности (the recognition test).

Результаты. Полученные результаты выявили статистически значимый эффект усвоения последовательности у испытуемых, выполнявших задание в конгруэнтных и неконгруэнтных условиях. При этом все испытуемые продемонстрировали низкий уровень эксплицитного знания последовательности (не более 51,9 % правильных ответов в тесте узнавания). Установлено, что имплицитное выучивание последовательности позволяет устранить эффект интерференции (задержку во времени реакции на неконгруэнтные стимулы).

Обсуждение результатов. Результаты подтвердили предположение о том, что эффект интерференции не снижает продуктивность имплицитного усвоения последовательности. Отсутствие значимых различий между группами, реагировавшими на конгруэнтные и неконгруэнтные стимулы, не позволяет в полной мере оценить влияние эффекта интерференции на эксплицитное усвоение последовательности. В целом данные проведенного исследования свидетельствуют в поддержку того, что эффект интерференции затрудняет экспликацию структуры последовательности.
Взаимосвязь склонности к киберагрессии, агрессивности и эмпатии в подростковом возрасте
Authors: Антипина Светлана С. , Микляева Анастасия В.
Published: August 2021

Введение. Исследование направлено на изучение взаимосвязей между склонностью к различным формам киберагрессии, агрессивностью и эмпатией в подростковом возрасте. Киберагрессия понимается как преднамеренное нанесение вреда другим пользователям Интернета; формы киберагрессии выделяются на основании типологической модели киберагрессии, предложенной К. Рунионсом, которая впервые применена для анализа онлайн-поведения российских подростков.

Методы. В исследовании приняли участие 196 подростков в возрасте 12–15 лет. Сбор эмпирических данных осуществлялся с помощью опросника «Типология киберагрессии», адаптированного для русскоязычной выборки в нашем исследовании, а также опросника уровня агрессивности Басса – Перри в адаптации С. Н. Ениколопова и шкалы эмоционального отклика А. Меграбяна в модификации Н. Эпштейна.

Результаты. Результаты исследования не позволили зафиксировать взаимосвязей между склонностью к киберагрессии, агрессивностью и эмпатией, которые были бы универсальными на протяжении всего подросткового возраста. Статистически значимые корреляционные связи склонности к киберагрессии с агрессивностью начинают фиксироваться только с 14-летнего, с эмпатией – с 15-летнего возраста. Агрессивность не является значимым предиктором киберагрессии подростков, эмпатия детерминирует склонность к киберагрессии (с отрицательным знаком) только среди 15-летних подростков.

Обсуждение результатов. Формулируется предположение о различном психологическом смысле киберагрессии на разных этапах подросткового возраста: киберагрессия как форма «социальных проб», не отражающая личностные особенности подростков, в начале подросткового возраста, и киберагрессия как форма проявления устойчивых личностных черт (прежде всего, дефицита эмпатии) в старшем подростковом возрасте.

Заключение. На основании полученных результатов сделан вывод о необходимости дифференцированного подхода к профилактике и коррекции киберагресссии подростков с учетом ее психологического смысла на разных этапах подросткового возраста.
Automatic detection of cyberbullying and threatening in Saudi tweets using machine learning

Published: August 2021

Social media has become a major factor in people's lives, which affects their communication and psychological state. The widespread use of social media has formed new types of violence, such as cyberbullying. Manual detection and reporting of violent texts in social media applications are challenging due to the increasing number of social media users and the huge amounts of generated data. Automatic detection of violent texts is language-dependent, and it requires an efficient detection approach, which considers the unique features and structures of a specific language or dialect. Only a few studies have focused on the automatic detection and classification of violent texts in the Arabic Language. This paper aims to build a two-level classifier model for classifying Arabic violent texts. The first level classifies text into violent and non-violent. The second level classifies violent text into either cyberbullying or threatening. The dataset used to build the classifier models is collected from Twitter, using specific keywords and trending hashtags in Saudi Arabia. Supervised machine learning is used to build two classifier models, using two different algorithms, which are Support Vector Machine (SVM), and Naive Bayes (NB). Both models are trained in different experimental settings of varying the feature extraction method and whether stop-word removal is applied or not. The performances of the proposed SVM-based and NB-based models have been compared. The SVM-based model outperforms the NB-based model with F1 scores of 76.06%, and 89.18%, and accuracy scores of 73.35% and 87.79% for the first and second levels of classification, respectively.

The outcome of post-disaster housing in Malaysia, particularly in Kuala Krai Kelantan, has remained unexplored. Therefore this paper attempted to discover the project impacts in Kampung Manek Urai Lama by investigating occupants' housing adaptation and modification. This study employed a case study method involving 18 respondents through purposive sampling. Findings revealed that the original house design does not consider several spatial needs and living traditions. The result established that these shortcomings were the main factors affecting housing modifications. The outcome of this study presents discoveries that can facilitate disaster management in Malaysia, particularly when planning for future post-disaster housing.

El papel de los actores institucionales como fuente de innovación para los productores de maíz en México
Authors: Sánchez Gómez Julia , Rendón Medel Roberto , Cuevas Reyes Venancio , Díaz José Julio
Published: August 2021

El objetivo de esta investigación fue analizar el papel que desempeñan los actores institucionales como fuentes de innovación en el sistema productivo del maíz en México. Se examinaron datos de 2.603 productores de maíz encuestados en nueve estados de la República Mexicana, y se utilizó la metodología del análisis de redes sociales (ARS) para estudiar la vinculación del productor con otros actores del sistema productivo en torno a la innovación. Los resultados mostraron que los productores de maíz tienen un índice de adopción de innovaciones (InAI) del 22,2 % y la participación de los actores institucionales como fuentes de innovación para el productor de maíz es limitada. Sin embargo, el 1,9 % de los productores que tenían un vínculo con algún actor financiero, gubernamental, de enseñanza o de investigación mostraron una diferencia estadísticamente significativa (p < 0,01) en su nivel de innovación, en comparación con quienes no tenían ningún vínculo. Además, los actores institucionales registraron la mayor cobertura de difusión de las innovaciones, con un promedio de 0,9 %, y presentaron una diferencia significativa (p < 0,05) en relación con otros actores. El papel de los actores institucionales es relevante para la innovación en el cultivo maíz debido al tipo de prácticas que enseñan a los productores y la cobertura de difusión que han alcanzado. Por esto, es necesario incrementar su vinculación, prestigio y colaboración en el sector agrícola para mejorar la productividad y competitividad de los productores.
Pectobacterium carotovorum: agente fitopatógeno causante de la pudrición blanda en la papa (Solanum tuberosum)

Published: August 2021

La papa (Solanum tuberosum) es un tubérculo de importancia a nivel mundial; es el cuarto cultivo de interés agronómico en términos de producción y área cultivada después del arroz (Oryza sativa), el maíz (Zea mays) y el trigo (Triticum aestivum). Pectobacterium carotovorum es un agente fitopatógeno de la papa que causa la podredumbre blanda del tubérculo, y es considerada como la enfermedad poscosecha más importante, pues genera grandes pérdidas económicas a nivel del almacenamiento. El presente documento pretende dar un esbozo de la biología del patógeno, los métodos existentes para la detección de dicho agente, la descripción del quorum sensing como mecanismo de la regulación de la expresión génica de sus factores de virulencia, el mecanismo de acción del patógeno, el proceso infectivo y los métodos actuales de control.

Authors: Anindita Nosa Septiana , Anwar Muslih
Published: August 2021

Pengembangan produk olahan susu kambing terfermentasi dan diperkaya dengan probiotik Bifidobacterium bifidum merupakan salah satu produk pangan fungsional (Functional Food) yang selanjutnya disebut sebagai Susu Bifidus. Susu bifidus sebagai salah satu produk fermentasi susu dapat dikonsumsi oleh masyarakat yang mengalami kesulitan mencerna laktosa (lactose intolerance). Daya terima konsumen terhadap susu kambing masih tergolong rendah dibandingkan dengan susu sapi, sehingga hal tersebut juga perlu diantisipasi. Penambahan ekstrak cengkeh (Syzygium aromaticum) pada susu Bifidus dapat digunakan sebagai alternatif senyawa aromatik alami, untuk menghilangkan aroma goaty pada susu kambing yang kurang begitu disukai oleh konsumen. Penelitian ini bertujuan untuk mengetahui pengaruh suplementasi ekstrak cengkeh terhadap viabilitas (daya hidup) dan aktivitas antibakteri Bifidobacterium bifidum serta kualitas kimia susu Bifidus. Parameter yang diamati pada penelitian adalah total Bifidobacterium bifidum, total bakteri dan luas zona bening susu Bifidus. Suplementasi ekstrak cengkeh sebesar 2% sebagai bahan suplementasi pada Bifidus milk dapat meningkatkan viabilitas probiotik Bifidobacterium bifidum. Ekstrak cengkeh dalam produk Bifidus milk berperan sebagai agen preservatif, didukung dengan adanya aktivitas antibakteri terhadap Staphylococcus aureus dan Salmonella typhimurium dan penurunan total bakteri pada Bifidus milk.

Jamur tiram mengandung asam glutamat yang tinggi sehingga potensial untuk dikembangkan menjadi bumbu penyedap pengganti monosodium glutamate (MSG). Pengembangan formulasi produk diperlukan untuk menghasilkan produk yang dapat diterima masyarakat dari segi cita rasa maupun secara ekonomi. Penelitian ini bertujuan untuk mengetahui formulasi yang dapat dikembangkan menjadi bumbu penyedap berbasis jamur tiram. Penelitian ini merupakan penelitian observasional laboratory, pada Juni 2018 - April 2019. Bahan dasar formula produk penelitian ini adalah tepung jamur tiram (Pleurotus ostreatus) yang dipreparasi dengan perendaman dalam larutan natrium bisulfit 6,25 ppm selama 10 menit, dilanjutkan dengan pengeringan menggunakan cabinet dryer dengan suhu 50 °C selama 30 jam. Penentuan formulasi terbaik dilakukan melalui dua tahap uji sensori. Uji sensori tahap I meliputi uji pembedaan dan uji hedonik, dengan menggunakan dua sampel formula tepung jamur dan produk MSG sebagai kontrol. Semua sampel dilarutkan dalam air hangat, kemudian disajikan masing-masing sebanyak 30 mL. Penilaian tingkat kesukaan menggunakan parameter warna, aroma, rasa, dan penilaian secara keseluruhan. Analisis data menggunakan uji Chi Square, sedangkan analisis data pada uji hedonik menggunakan uji Mann-Whitney. Data dianalisis menggunakan software statistik SPSS Statistic 21. Penelitian ini melibatkan sejumlah 20-30 panelis tidak terlatih. Hasil uji sensori pada tahap I digunakan sebagai kontrol pada uji sensori tahap II. Formulasi produk lainnya dibuat dengan substitusi kombinasi gula-garam dengan perbandingan tepung jamur tiram, garam, dan gula masing-masing 5:2:1 dan 5:3:2 (b/b/b). Analisis data secara deskriptif dan disajikan dalam bentuk diagram. Hasil penilaian tingkat kesukaan panelis menunjukkan nilai tertinggi pada formula dengan perbandingan tepung jamur, gula, dan garam sebesar 5:3:2 (b/b/b), sehingga formuli ini dapat dikembangkan menjadi produk bumbu penyedap berbasis jamur tiram.
