The article focuses on conceptual factors that contribute to the formation of the school as an exemplary educational institution. The questions about effective administration and leadership are answered by analyzing the findings and insights of educational theorists. What are the moral criteria of leadership and the ambiguous and complex decision-making process? How the insights from important work design theories correlate with important conceptual approaches to school management. An important emphasis is placed on diversity and the concept of the school microcosm: how effective administration can increase the self-efficacy of teachers, which in turn always positively affects the academic performance of students. The scientific novelty of the article discusses the views of heads of public schools in Georgia, their subjective experiences, and recommendations, together with the theoretical and conceptual tools of school management. Through the phenomenological analysis conducted with school leaders in Georgia, we will get to know the professional skills and strategies that lead to the strengthening of the school’s pulse and focusing on the so-called “school of the future” model.

The study examines the impact of various theories on the reflection and transmission phenomena caused by obliquely incident longitudinal and transverse waves at the interface between a continuously elastic solid half-space and a thermoelastic half-space, using multiple thermoelastic models. Numerical calculations reveal that the thermoelastic medium supports one transmitted transverse wave and two transmitted longitudinal waves. The modulus of amplitude proportions is analyzed as a function of the angle of incidence, showing distinct variations across the studied models. Energy ratios, derived from wave amplitudes under consistent surface boundary conditions for copper, are computed and compared across angles of incidence. The results demonstrate that the total energy ratio consistently sums to one, validating energy conservation principles. Graphical comparisons of amplitude proportions and energy ratios for SV and P waves across different models illustrate significant differences in wave behavior, emphasizing the influence of thermoelastic properties on wave transmission and reflection.

Major principles of organizational management like unity of command and unity of direction are quite important to foster co-ordination and efficiency in organizations. Since Islamic management is an offshoot of the modern Western management theories these principles have considerable relevance to Islamic management as well. This paper aims to discover how Islamic principles can solve modern problems of organizational management in order to demonstrate an interdependent system that teaches ethics and management. This paper attempts to offer an analytical discussion regarding Islamic views on the challenges that emerge regarding the need for cohesion in managing any organization. On the basis of a conceptual review, it highlights how unity of command and unity of direction can influence inspiring better management at all levels positively. Such clarification tries to elicit the Islamic interpretation that may lead to increased workforce commitment due to their motivation emanating from religion, contribute principles that will benefit the value addition process of labor and management’s decision-making process towards wider organizational goals, and enrich literature on management from Islamic principles and thoughts. This text succinctly examines the principles of unity of command and unity of direction that promote the development of management work ethics and the implications of Islamic management. The paper reviews the principles of unity of command and unity of direction as derived from The Holy Qur’an and Hadith, and examines various empirical studies conducted in different countries. These discussions subsequently bring out that the Islamic approach is comprehensive and practically relevant in the interest of present-day organizations. The paper concludes that intention and purity of hearts, regardless of the leadership styles of management, will direct the leaders and workforce to continually strive hard and give their best in their organizational management functions.

This paper concerns a miniature gasifier fed with a constant ambient-pressure flow of air to study the pyrolysis and subsequent combustion stage of a single wood pellet at T = 800 ℃. The alkali release and the concentration of simple gases were recorded simultaneously using an improved alkali surface ionisation detector and a mass spectrometer in time steps of 1 s and 1.2 s, respectively. It showed alkali release during both stages. During combustion, the MS data showed almost complete oxidation of the charred pellet to CO₂. The derived alkali release, “O₂ consumed”, and “CO₂ produced” conversion rates all indicated very similar temporal growth and coalescence features with respect to the varying char pore surface area underlying the original random pore model of Bhatia and Perlmutter. But, also large, rapid signal accelerations near the end and marked peak-tails with O₂ and CO₂ after that, but not with the alkali release data. The latter features appear indicative of alkali–deprived char attributable to the preceding pyrolysis with flowing air. Except for the peak-tails, all other features were reproduced well with the modified model equations of Struis et al. and the parameter values resembled closely those reported for fir charcoal gasified with CO₂ at T = 800 ℃.

This study evaluated the efficiency and productivity of the manufacturing industries of Singapore. Singapore is one of the world’s most competitive countries and manufacturing giants. All 21 manufacturing industries as classified by Singapore’s Department of Statistics were included in the study as decision-making units (DMUs). Using the Malmquist DEA on data spanning 2015–2021, we found that excerpt for the Paper and Paper product industry, all industries recorded positive total factor productivity (TFP). TFP ranged from 0.977 to 1.481. In terms of technical efficiency, 14 out of 21 industries showed positive efficiency change. The highest TFP was recorded in 2020 and the lowest in 2016. By measuring and improving efficiency, industries in Singapore can achieve cost savings, increase output, and enhance their competitiveness in the global marketplace. In addition, efficiency measurement can help policymakers identify potential areas for improvement and develop targeted policies to promote sustainable economic growth. Given these benefits, performance measurement is inevitable for industries and policymakers in Singapore to achieve economic objectives. Manufacturing industries need to find ways to manage the size and scale of operations as we flag this as an area for improvement.

The use of different energy sources and the worry of running out of some of them in the modern world have made factors such as environmental pollution and even energy sustainability vital. Vital resources for humanity include water, environment, food, and energy. As a result, building strong trust in these resources is crucial because of their interconnected nature. Sustainability in security of energy, water and food, generally decreases costs and improves durability. This study introduces and describes the components of a system named “Desktop Energetic Dark Greenhouse” in the context of the quadruple nexus of water, environment, food, and energy in urban life. This solution can concurrently serve to strengthen the sustainable security of water, environment, food, and energy. For home productivity, a small-scale version of this project was completed. The costs and revenues for this system have been determined after conducting an economic study from the viewpoints of the investor and the average household. The findings indicate that the capital return period is around five years from the investor’s perspective. The capital return on investment for this system is less than 4 years from the standpoint of the households. According to the estimates, this system annually supplies about 20 kg of vegetables or herbs, which means about one third of the annual needs of a family.
