Natural and Artificial Intelligence Interactions in Digital Networking: A Multilayer Network Model for Economic Value Creation
Authors: Moro-Visconti Roberto 
Published: November 2024

This study investigates the integration of natural intelligence (NI) and artificial intelligence (AI) within traditional firms linked through a multilayer network framework. The research explores this central question: How can the integration of NI and AI, facilitated by copula nodes, drive economic value creation in digitized firms?
The paper combines theoretical and empirical results of the observed increments in cost-benefit marginality linked with AI adoption by checking out testing in various domains such as manufacturing, retailing, finance, etc. The performance of the model shows enhanced efficiency and decision-making, as well as savings in costs. Copula nodes that connect multilayer networks blend NI with AI, boosting overall value. Unlike existing studies, this framework operationalizes copula nodes to capture real-time dependencies between human-driven and AI-driven processes, offering a comprehensive view of economic value creation across digitized firms. A methodology section outlines the empirical validation process conducted across multiple industries (manufacturing, retail, and finance), providing key insights into efficiency, decision-making, and cost optimization.
The practical implications offer a strategic pathway for firms to enhance profitability and competitiveness in the digital age. The results underscore the importance of strategically integrating AI with human intelligence to maximize economic outcomes.

Examining intersectionality of social identities in Birim Central Municipality in the Eastern Region of Ghana
Authors: Evelyn Owusu-Yeboah  , Vivian Owusu Yeboah  
Published: November 2024

The aim of this current review is to provide a detailed analysis of literature on the intersectionality of social identities and their impact on family dynamics, relationships, and support systems in Birim Central Municipality, Eastern Region of Ghana. The objective of the research is to investigate how overlapping social identities such as gender, ethnicity, religion, and socioeconomic status shape the experiences of families within the municipality. Google scholar, Scopus (Elsevier) and Science Direct (Elsevier), were a few of the databases used for the review. The findings reveal that the intersection of social identities creates both challenges and opportunities for families. Gender roles, ethnic norms, religious beliefs, and economic conditions interact to influence household responsibilities, access to resources, and decision-making processes. Families from marginalized ethnic and socioeconomic groups often face greater obstacles in securing support, while traditional gender norms continue to shape household dynamics, especially in lower-income families. Religious beliefs also play a significant role in shaping family values and practices, contributing to both cohesion and tension in some households. In conclusion, the intersectionality of social identities plays a critical role in shaping family dynamics in Birim Central Municipality. Policies and programs aimed at supporting families must consider these overlapping factors to ensure equity and inclusivity. To support family cohesion and social fairness in the Birim Central Municipality, the study recommends focused interventions that cater for the unique needs of families impacted by the confluence of gender, ethnicity, religion, and socioeconomic position.

Exploring Employees’ Perception of the Effectiveness of Public Employees’ Performance Management Information System: A Case of the Judiciary of Tanzania
Authors: Silidion Beatrice Dominic , Rutenge Mary Mohamed 
Published: November 2024

An effective performance management system is a significant challenge in the public sector. The Government of Tanzania has been trying different methods to overcome this challenge. It recently introduced the Public Employees Performance Management Information System (PEPMIS). This study explored employees' perception of the effectiveness of this system using the Judiciary of Tanzania as a case. Expectancy theory was used in this study to explore employees’ expectations toward the effectiveness of the introduced Performance Management System in Tanzania. For that purpose, a case study design using a quantitative research approach was used. A sample of 142 respondents drawn from 219 staff from the Judiciary of Tanzania was used. Stratified sampling, simple random sampling, and purposive sampling were used to obtain different categories of respondents. The data collection methods were questionnaires. Data was analyzed using tabulation, frequency and percentage, which SPSS drove. It was revealed that employees of the Judiciary of Tanzania perceive PEPMIS to be effective. This perception was influenced by the perception that it was fair and accurate, it allowed for timely provision of feedback, employees considered themselves skilled enough to use the system, the clarity of the assessment procedure, its performance assessment was linked to the goals and targets, performance was linked to rewards, and training was provided. PEPMIS, being perceived as effective, is an opportunity for the government, policymakers, and all stakeholders involved to ensure adequate practice and rectify weaknesses to maintain the public sector's reputation. To conclude, PEPMIS has been shown to meet employees' expectations. Hence, we recommend continuous training for employees on performance management systems. Also, the government and public sector organisations must enact policies that will help enforce the system, including seeing to it that employees are less burdened by the requirement to fill their performance into the system daily.

Este estudo apresenta uma análise epidemiológica das artrodeses de coluna realizadas pelo Sistema Único de Saúde (SUS) no Brasil entre 2015 e 2024, totalizando 98.798 procedimentos. As regiões Sudeste e Sul foram responsáveis pela maior parte das cirurgias, concentrando 72,1% do total, com destaque para os estados de São Paulo e Paraná. A evolução temporal dos dados demonstra uma redução gradual no número de cirurgias até 2019, com um declínio abrupto no período da pandemia de COVID-19, seguido de uma recuperação a partir de 2022. O procedimento mais comum foi a artrodese toraco-lombo-sacra (52,7%), seguida pela cervical anterior, que respondeu por 22.183 cirurgias. Houve uma predominância do caráter de urgência (58,4%), especialmente nas artrodeses cervicais e cérvico-torácicas posteriores. A distribuição das técnicas cirúrgicas variou conforme a região anatômica: a via anterior foi preferida para a estabilização cervical, com predominância de um ou dois níveis, enquanto as cirurgias toraco-lombo-sacras foram principalmente por via posterior e envolvendo múltiplos níveis vertebrais. Estes achados destacam a importância de políticas de saúde pública que promovam um acesso mais equitativo a procedimentos de alta complexidade no SUS.

В статье приведен анализ влияния направления армирования в композиционном материале относительно циклической нагрузки на неоднородность распределения локальных упругих деформаций, измеренных тепловым методом неразрушающего контроля. В настоящем исследовании за счет термоупругого эффекта показана возможность оценки локального распределения напряжений (деформаций) в объекте контроля. Температурное поле термограммы линейно зависит от напряжений и деформаций в локальных точках объекта контроля. Были проведены исследования термограмм ламинатов из композиционного материала с различной укладкой волокнистого наполнителя (стекловолокно) с эпоксидной матрицей при циклической нагрузке. Для анализа отличий в локальном распределении деформаций были использованы статистические данные, рассчитаны коэффициенты вариации. Для визуализации уровней деформаций был использован метод кластеризации и усреднение по длине ламинатов значений распределения температуры. Получены числовые характеристики распределений локальных температур, которые показали на более их однородное распределение при армировании материала по направлению нагружения детали.
The purpose of the study is to analyze the influence of the direction of reinforcement in a composite material relative to the cyclic load on the heterogeneity of the distribution of local elastic deformations measured by the thermal method of non-destructive testing. In this study, due to the thermoelastic effect, the possibility of assessing the local distribution of stresses (strains) to the field of the test object is shown. The temperature field of a thermogram linearly depends on stresses and strains at local points of the test object. Thermograms of composite material laminates with various placements of fiberglass filler (fiberglass) with an epoxy matrix under cyclic loading were studied. To analyze differences in the local distribution of deformations, statistical data were used and coefficients of variation were calculated. To visualize the levels of deformation, the clustering method and averaging of temperature distribution values over the length of the laminates were used. Numerical characteristics of local temperature distributions were obtained, which showed their more uniform distribution when reinforcing the material in the direction of loading of the part.

Статья посвящена исследованию влияния процесса старения на противоизносные свойства смазочных композиций на основе растворов дитиофосфатов цинка и молибдена в базовых маслах И-20А, ПАО-6 и VHVI-6 (класса вязкости по ISO VG–32). Дитиофосфат цинка известен как противоизносная и антиокислительная присадка, а дитиофосфат молибдена – как высокотемпературная антифрикционная присадка. Их противоизносные и противозадирные свойства были оценены дважды по единой методике на четырехшариковой машине по ГОСТ 9490-75. В первый раз были испытаны свежие смазочные композиции, затем эти композиции были перед вторым испытанием искусственно состарены методом высокотемпературного каталитического окисления по методике ВНИИ НП № 42/607 от 10.05.1983 г. Анализ сравнения результатов трибологических испытаний на свежих и на состаренных смазочных композициях, в состав которых входят антиокислительная присадка ДФ-11 показал, что в ряде случаев кислотное число не увеличивается, что следует отнести на счет применяемых в составе таких композиций антиокислительных присадок.
The article is devoted to the study of the influence of the aging process on the anti-wear properties of lubricating compositions based on solutions of zinc and molybdenum dithiophosphates in three oils (I-20A, PAO-6 and VHVI-6, which have a similar viscosity). Zinc dithiophosphate is an antiwear additive, and molybdenum dithiophosphate is a high-temperature antifriction additive. Their antiwear and antiseizure properties were evaluated twice by a single method on a four-ball machine according to GOST 9490-75. The first-time fresh lubricating compositions were tested, and the second time these compositions were artificially aged before the tests by the high-temperature catalytic oxidation method according to the VNII NP No. 42/607 method. Analysis of tribological tests results comparison on fresh and aged lubricating compositions containing antioxidant additives (for example, DF-11) showed that in some cases the acid number practically does not increase, which should be attributed to the powerful antioxidant used in such composition.
