Employees from diverse backgrounds have been claimed to perform better; nevertheless, this link has been studied sparingly in the Egyptian setting. This paper addresses this gap by experimentally analyzing the link between employee performance and gender, educational background, and ethnic background. To investigate this link, a usable model was created, and data was collected from 269 academic staff members at private Egyptian institutions. PLS analysis was used, and the result revealed that educational and ethnic backgrounds have a positive effect on employees’ job performance whereas, the impact of gender background on employee’s job performance was found to be insignificant. Furthermore, the research findings disclose that the education and ethnic background of the employees mediates the relationship between employees’ job performance and gender diversity. Future research is yet to validate these results.

The article discusses principal issues related to lean production and consumption, providing the author's perspective on the factors and initiatives necessary for their implementation. The paper emphasizes the importance of each stakeholder's role in sustainable development. The agricultural market is analyzed, and general steps for implementing a Sustainable Development Strategy are proposed, including simulations of sales and pricing policies after the introduction of sustainable development aspects. With the world's population growing and resources declining, there is a need to meet increasing demand while also conserving water resources, agricultural land, and promoting environmentally friendly labour practices. To achieve this, countries must adopt innovative approaches to responsible consumption and sustainable production, particularly considering the socio-economic impact of COVID-19. Therefore, it is essential to develop an innovative model of sustainable consumption and production. COVID-19 has become a catalyst for socio-economic change, highlighting the adaptability of countries to change and the necessity for effective restoration and implementation of sustainable production and consumption models. This article explores the management of responsible consumption and sustainable production enterprises in the context of glocalization. It analyses the impact of global trends and local contexts on businesses striving for sustainable development. The article emphasizes the role of leadership, strategic planning, and the implementation of effective management practices in achieving these goals. The authors examine various models and approaches to managing responsible consumption and sustainable production, including concepts of green manufacturing, circular economy, and corporate social responsibility. They consider advanced practices and initiatives in these areas that are already successfully implemented by large and small enterprises. The article also investigates the influence of glocalization on enterprise management. Glocalization is defined as the convergence of global and local factors influencing businesses. It highlights the need for enterprises to adapt their strategies and operations to the specific cultural, social, and environmental contexts in which they operate, while also addressing global challenges related to responsible consumption and sustainable production.

Electrosurgical generators (ESGs) are currently the most widely used surgical technology for clinical operations. The main disadvantage of ESGs is their output power is irregular due to the variable tissue impedance. The heat dissipation caused by the high amount of thermal energy generated leads to medical complications for both patient and surgeon. In this research, various inverter topologies and power controllers are investigated to specify the best structure that ensures best performance. The type of inverter topologies investigated are three level and five level, while the PID structures investigated are integer order (IO-PID) and fractional order (FO-PID). The simulation results indicate that FO-PID with five level inverters is better than IO-PID with three level inverters in terms of minimum heat dissipation rate and THD of the output voltage and current.

Performance appraisal in human resource management is a function that evaluates employees’ knowledge, skills, and abilities in executing their job. To assess this appraisal, the employees’ key performance index (KPI) can be used. Recently, office politics has been indicated as an activity that may ruin employee-employer relationships and turn the office ecosystem unharmonious. The influence of organizational politics must be avoided during the performance appraisal process. This work depicted practical knowledge and theoretical gaps of the previous studies. Among them are leniency, straightness and stereotype behavior errors. This research was conducted to assess dimensions of organizational politics as one more error in the employee’s performance appraisal. The presented study considered a questionnaire directed to 274 officers and clerical staffs who were selected randomly through proportionate stratified sampling method in one of the Malaysian government financial sectors located in Kuala Lumpur, Malaysia. In total 271 questionnaires were returned and used in this study. This work employed Questionnaire of Political Considerations in Performance Appraisal by using robust statistical techniques for testing and validating the results. This study has successfully extracted three reliable dimensions of politics in performance appraisal, namely acquiring benefit, human relations, and control. In addition, this work developed a new conceptual model together with a dynamic and practical recommendation for top management in this field used to avoid the extant error factors.

Every year, the interest in functional nutrition is growing in the world. Consumers are increasingly rejecting products containing sugar, artificial preservatives, dyes, flavorings, flavor enhancers, etc. There is a growing public interest in healthy food products and the ingredients used in these products. Despite the increase in the price of such products, marketing research confirms the demand for them and the willingness of the population to "overpay for naturalness". The article is devoted to the development of the formulation and technology of a pastila-type product with a functional purpose using non-traditional raw materials (coconut sugar, fructose and blueberry powder) instead of sugar. The organoleptic and physicochemical indicators of the quality of new products were determined. The pastila-type products are enriched with protein, dietary fibers, minerals (potassium, calcium, magnesium, zinc) and vitamins (C, PP, groups B, A).

The SME lending covers a list of its needs related to its day-to-day performance, fixed assets, development. Existing methods of identifying impact on economic indicators from using loans by SMEs are limited. The aim of the research is to develop a methodology which allows reveal the impact of SME lending on business value added on macroeconomic level. The methodology is based on correlation regression analysis in order to identify the level of loan influence on business development, value added in particular, due to the lack of adequate methods for SME development forecasting. The obtained results are sufficient for medium business and be used in forecasting medium business development in Ukraine. For small business model has insufficient density of the relationship between indicators, therefore, it was proposed to use additional factors as equity; liabilities and non-economic factors exemplified as the level of shadow economy.

The paper presents a forecast of the economic security of the inter-industry complex through the construction of a simulation model. The authors considered the possibility of using an econometric model in predicting the level of economic security of the inter-industry complex. The goal was to form a definition of the "inter-industry complex", as well as to study the issues of conceptual and fundamental methods of econometric modeling and forecasting the development of regional industry markets in dynamics. A range of issues related to the main components of economic security in the inter-industry complex has been allocated for scientific work in order to analyze the impact of the components of economic security on the integral indicator. The paper uses a methodology for predicting the structural and spatial-temporal dynamics of interbranch complexes, which includes new and refined methods of modeling and forecasting. As a result, the authors proposed the definition of "inter-industry complex", "economic security in the inter-industry complex", as well as the general provisions of the methodology for econometric modeling and forecasting the level of economic security of the inter-industry complex. The paper presents a full-scale simulation model that allows you to set, evaluate and make a decision using large nonlinear data. This kind of system contains dynamic and retarded data, which makes it possible to apply econometric modeling in automatic calculation.

The shelf life of pineapple is significantly influenced by storage temperature and can be prolonged by maintaining an optimal temperature range of 5-12°C. However, there is still the problem of internal browning (IB) in the long-term storing of fresh harvest at cold temperatures. Postharvest application of 380 µM ABA (Abscisic Acid) to the crown, which is a source of ABA endogenous was found to suppress IB, while the concentration of 95 µM was not effective. Therefore, this research aimed to determine the response of GP3 and MD2 clones to postharvest treatment with the application of 50 mg/L ABA, chitosan and decrowning on the IB severity and other fruit qualities. The experimental design used a Completely Randomized Design with 3 factors of clone (GP3 and MD2), decrowning (crown and crownless), and fruit coating [chitosan 1%, ABA 50 mg/L, ABA + chitosan mix, and control (H2O)]. The fruits were kept at 7oC and observed at 0, 3, 6, 9, 16, 23, 30, and 37 days. The results showed that MD2 was significantly lower IB than GP3 and IB severity negatively correlated with ascorbic acid (AsA) content. MD2 had lower fruit weight loss (FWL) and skin dehydration (SD), higher AsA, soluble solid content (SSC), and SSC/titratable acidity (STA) ratios compared to GP3. The crown + ABA treatment decreased the IB severity of GP3, with a level of 0.75% after 37 days which was lower than crown + H2O by 9.17% and crownless + H2O by 8.42%. ABA treatment also showed higher SD and FWL, while AsA, SSC, TA, and STA were not different from the control.

The results showed that MD2 was significantly lower IB than GP3 and IB severity negatively correlated with ascorbic acid (AsA) content. MD2 had lower fruit weight loss (FWL) and skin dehydration (SD), higher AsA, soluble solid content (SSC), and SSC/titratable acidity (STA) ratios compared to GP3. The crown + ABA treatment decreased the IB severity of GP3, with a level of 0.75% after 37 days which was lower than crown + H2O by 9.17% and crownless + H2O by 8.42%. ABA treatment also showed higher SD and FWL, while AsA, SSC, TA, and STA were not different from the control.","PeriodicalId":32240,"journal":{"name":"Acta Innovations","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-02-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46459650","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
