The purpose of this study is to introduce working capital efficiency multiplier (WCEM) as a direct profitability measure of working capital management. The existing accounting measures in the literature establish an indirect approach to study the relationship between working capital efficiency and profitability of the firms.

Using the help of a set of companies from CMIE Prowess database, the study introduces WCEM as a direct profitability measure of working capital efficiency.

In this study, a new direct measure of working capital efficiency is introduced which is multiplicative in nature. WCEM is a product of three components, namely, WACC, ratio of the sum of trade receivables and inventories to trade payables and ratio of net working capital (NWC) to net sales.

The importance of direct measure like WCEM could be enormous in performance evaluation of a firm. It can be used as an indicator for choosing a suitable investment opportunity by an investor. This is due to the fact that the firm that is highly efficient in managing working capital is less exposed to liquidity risk. At the same time, the firm is less dependent on external financing. Therefore, such firms eventually create more value for their shareholders. Another indication that WCEM provides is to gauge the bargaining power of the firm and its competitive position in the market. Lower WCEM indicates higher bargaining power of a firm across the value chain, and its superior position relative to its competitors.

Most of the studies on WCM are of the empirical type and there is a complete dearth on theoretical framework. Researchers hereafter can consider WCEM as one of the financial performance variables in place of the existing measures such as return on asset (ROA), return on invested capital (ROIC), return on equity (ROE), gross operating income (GOI) and net operating income (NOI) and thereby can contribute new empirical insights through their research outcomes.

This study addresses the challenge of integrating entrepreneurial competences development into the traditionally structured engineering curriculum, recognizing its potential contribution to job creation. Specifically, this study proposes a course design that intersects project management and entrepreneurial disciplines, adopting a challenge-based learning approach.

Considering a list of common features that entrepreneurs and engineers—in the role of project managers—should excel at, and building upon the principles of experiential learning, this study proposes and describes a course design that is expected to help engineering students develop entrepreneurial competences. Through a series of assessment instruments and descriptive statistics, the study evaluates its implementation in a pilot test applied in a Project Management course at a Spanish university.

The results demonstrate a significant improvement in students' entrepreneurial competences after completing the course. Noteworthy variations in receptiveness to skill development among different personality profiles are observed. Gender differences are minimal, with the exception of women exhibiting heightened self-perception in the autonomy dimension.

This study explores the common features shared by two often-disconnected disciplines, namely engineering and entrepreneurship. It suggests that integrating both perspectives through a challenge-based course design can enhance entrepreneurial competences among engineering students without compromising the specific knowledge gained from engineering programs. Engaging students in such pedagogical experiences not only fosters entrepreneurial competences but also contributes to their professional and personal growth.

This paper aims to develop and validate a strategy for reducing construction waste (CW) generated during the design process (DP) in architectural design firms (ADFs) in Egypt.

Qualitative and quantitative research methodology was designed to accomplish four objectives. The literature review investigated DP, CW, waste management (WM) and WM strategies (WMS). Three case studies were analysed to investigate the role of WMS towards reducing CW during DP. A survey questionnaire was conducted with a representative sample of ADFs in Egypt to assess their perception and application of WMS during DP. Lastly, a strategy was developed and validated to reduce CW generated during DP.

Through literature review, the research identified the highest 40 causes of CW during the DP and classified them into 13 categories. Despite early promotion of WMS to reduce CW at its source, Egypt and other countries with similar construction market characteristics lack laws and regulations to address CW during the DP, with current codes primarily focusing on post-occurrence issues. In addition, analysis of three case studies showed that CW was reduced by adopting WMS during the DP. Findings of data analysis revealed that ADFs have an average knowledge of WMS and a low awareness of Egyptian laws and WMS during DP. “Prefabrication” was the highest-ranked strategy for CW reduction during DP. Several challenges hamper the implementation of WMS. The “preparation and briefing” was ranked the most common design stage where CW causes occur, while “waiting” was ranked the most common form of CW. These findings informed the research outcome and helped in the development of the proposed strategy.

The proposed strategy was developed taking into account the results of the survey questionnaire which was conducted in ADFs in Egypt where the authors reside, and such a strategy is needed. However, it could be applied in other countries that share the same characteristics of the architectural DP as well as the causes of CW and WMS implementation challenges.

This research presents a practical strategy to reduce CW generated during the DP. It was based on the findings of literature review, case studies and survey questionnaire. The strategy was explained in a workable way to include the required activities; tools and techniques; involved personnel and needed resources. The strategy was validated by a representative sample of ADFs in Egypt to ensure its practicability and viability for implementation towards developing a sustainable built environment. The practical application of the strategy will have long-term and short-term benefits. The long-term benefits include improving the social, economic and environmental aspects of sustainability during the design and construction phases in Egypt. In the short term, application of the strategy will improve the cooperation between design and construction teams, reduce the negative impact of CW production and enhance the quality of construction projects in Egypt.

Despite the need to reduce CW during DP, a practical strategy is lacking in Egypt, where laws are focused on dealing with CW after its existence. This research studied a topic that received scant attention in construction literature. It developed and validated a strategy to reduce CW during DP, which represents a synthesis that is novel and creative in thought and adds value in a manner that has not been previously explored.

This study examines the effect of working capital management on profitability of listed manufacturing firms in Ghana.

The study employs a quantitative research approach within the causal research design using a balance panel of 20 manufacturing listed firms from 2015 to 2019.

The study reveals that inventory management, account receivables, account payables, cash conversion cycle, current asset, current ratio and firm size have positive effects on return on assets (ROA) and return on return on equity(ROE) whilst leverage affects them negatively.

The study only covers 20 manufacturing firms generally due to data unavailability. However, the outcome has useful information for manufacturing firms.

The study brings to light effective ways of improving the profitability of manufacturing firms through policies.

The findings are beneficial to manufacturing firms and countries for the purpose of improving performance of firms and welfare of the people through direct and indirect chain effects of increasing investments, remunerations and scales of production.

This study adds insights into the existing literature on working capital management namely methodology, effects of components on profitability of manufacturing firms and socioeconomic implications- evidence from Ghana.

This research investigates (1) the impacts of working capital investment policy and working capital financing policy on firms’ performances (profitability and market value) and (2) the impact of profitability on market value. Data are gathered from 68 companies listed in the Stock Exchange of Thailand covering production sector. Data collected from 2012 to 2016 are analyzed using path analysis to measure the impacts of working capital policy on performances and examine the consistency of the model and the empirical data.

The model is found to be consistent with the empirical data; the probability level is 0.085, χ ²/df is 2.96, CFI is 0.951, GFI is 0.979, IFI is 0.957, and RMR is 0.004. The result reveals a statistically significant positive relationship between working capital investment policy and profitability. In addition, working capital investment policy affects market value through profitability as a mediator variable. However, there are significant negative impacts of working capital financing policy on profitability and market value. Overall, it can be implied that companies which adopt conservative working capital investment policy and conservative working capital financing policy can increase their profitability and market value.

Large amounts of uranium, radium and radium products are redistributed throughout the environment owing to the use of phosphate fertilizers. Potential radiological impacts resulting from direct exposure, inhalation and ingestion of foods grown with fertilizers are discussed. This paper describes a simple method to measure exhalation rate of ²²²RN from phosphate fertilizers, clay and potatoes in a laboratory and in a more economical way. Three Egyptian factories of phosphate fertilizers were selected in this study (Assuit, Abu Zaable and Kafr El Ziat).

Although the hospitality sector is considered the most active and profitable sector in the Egyptian economy, it suffers from the non-stop immigration of skilled manpower and the high rates of labor turnover. One of the apparent solutions for this problem that could be implemented is empowering Egyptian females to play an active role in the success of this sector. Females faced many obstacles while working in hospitality, including prevailing social perception, the culture of shame, the traditional negative view of feminine hoteliers, long working hours and the shift system, which led to weak females' desire to enroll in the hospitality field. The study aims to determine how empowering Egyptian women in the hospitality industry affects staff turnover.

To achieve the aim of the study, a sample of four- and five-star resorts in Red Sea, Egypt, was under study. A self-administrated questionnaire was addressed to female hotel employees, and 140 forms were statistically analyzed in addition to 14 semi-structured interviews with hospitality experts.

The study recommends that hotels should start re-tailoring policies to activate Egyptian females' role in reducing the high rate of hospitality labor turnover through increasing their work engagement (WENG) (as a mediator) by adopting a decent work environment and motivating them to get promoted to hold senior positions.

In spite of some noteworthy contributions, the authors would like to point out certain shortcomings. The sample was homogeneous, consisting of female hotels employees in Egypt, but the findings are generalizable to other Arabian communities. Nonetheless, the authors feel that they have supplied some suggestive evidence, even for the most careful reader who wants to further study these elements of working attitudes in the hotel business.

According to the authors' knowledge, this study is among the few studies covering females' reluctance to continue working in the hospitality field.

The current status of nanotechnology research and development in Jordan is analyzed. In recent years, Jordanian institutions demonstrated considerable interest in the development and production of nanotechnology. Here the purpose of this paper is to provide detailed information about the status of nanotechnology in Jordan in terms of several factors that influence selectivity in nanotechnology and the number of published peer-reviewed research articles.

Several factors that influence selectivity in nanotechnology and the number of published peer-reviewed research articles were analyzed. A detailed analysis of the collected data reveals that the number of publications, citations, and patents is highly dependent on the amount of research fund.

The development in nanotechnology is associated with presence and accessibility of sensitive laboratory equipment. The nanotechnology research output in Jordan is still lower than it should be due to the lack of necessary laboratory infrastructure. This is due to the insufficient funds allocated to scientific research, the restrictive access to available instruments and the bureaucracy of some governmental departments. Compared to some developed countries, Jordan is noticeably behind in developing a nanotechnology system of research and industry. It will take time as well as technical and financial resources in order to achieve an advanced level in the field of nanotechnology in Jordan. Nevertheless, many Jordanian researchers are doing their best and are producing some good research articles.

The purpose of this paper is to better understand the role of virtual teams in organizational transformation. This conceptual paper explores the significant influence of the digital era on organizational structures, specifically focusing on the transformative shift toward virtual teams (VTs) with a strong message for small and medium-sized enterprises (SMEs).

The article is based on the review of existing concepts identified in the previously published studies and their critical reflection. The literature search was conducted in the Web of Science database in May 2024 by using the keywords VTs, Digitalization and SMEs.

In the rapidly changing business environment, organizational transformation is no longer a choice but a prerequisite for the survival and growth of businesses. It is argued in the study that organizations, especially SMEs, need to embrace VT despite the challenge of a comprehensive theoretical framework for understanding VT and the need for the development of a novel theory, which has been a reoccurring phenomenon and subject of debate in the literature. Furthermore, the paper underlines the necessity of providing essential preparation and training for VTs, focusing on both technological skills and collaborative work methods. In the context of SMEs, the paper argues that collaboration with external partners and the adoption of virtuality can enhance competitiveness. In the end, the emergence of virtual learning communities is proposed as a solution, providing a platform for SME owners/managers to share experiences and acquire new skills.

Overall, this study provides several recommendations for future research on VTs.

The purpose of this study is to evaluate the effect of the probiotic addition (Lactobacillus paracasei ssp.) on the physicochemical characteristics and antioxidant capacity of white grape juice during refrigerated storage (4°C/28 days). This paper also aims to evaluate the survival of the probiotic culture in the product and under simulated gastrointestinal conditions.

Two formulations of white grape juices were evaluated, one with 2 per cent of probiotic culture addition and the other of pure juice.

The addition of probiotic culture resulted in products with a darker-reddish coloration (L* = 30.6-30.8 and a* = 0.6-0.9) and a lower content of total phenolic compounds (599-697 µg EAG mL⁻¹) (p = 0.05). However, it improved the color stability and maintained the antioxidant activity 1,1-diphenyl-2-picrylhydrazyl (p > 0.05). The viability of the probiotic culture (>10⁹ colony forming unit · 200 mL⁻¹) in the juice was maintained during 21 days of storage, but in simulated gastrointestinal conditions, the functional properties could be guaranteed during the 28 days of refrigerated storage.

The white grape juice is a suitable medium for incorporation of Lactobacillus paracasei.

The survival of the probiotic cultures to the simulated gastrointestinal tract may be significant, even if the product does not have the recommended minimum counts.
