The main objective of the paper is to develop an investment model using data envelopment analysis (DEA) that provides a decision-making framework to allocate resources efficiently, such that the relative efficiency is improved within an available investment budget.

Firstly, DEA models are used to evaluate the efficiency of the departments relative to their peers and providing benchmarks for the less efficient departments. Secondly, the inefficiencies in departments are identified. Finally, for the less efficient departments, a decision-support system is introduced for optimizing resource allocation to improve efficiency.

Five of the 18 academic departments were determined to be inefficient, and benchmark departments were found for those departments. The most prevalent causes for inefficiency were the number of undergraduate students per faculty and the number of graduate students. Results from the investment model for department 12 suggest increasing the number of faculty by 2 units and H-Index by 0.5 units, thereby, improving the relative efficiency of the department by 6.8% (88%–94%), using $290,000 out of $500,000 investment budget provided.

When an investment budget is available, no study has used DEA to develop a decision-support framework for resource allocation in academic departments to maximize relative efficiency.

This paper aims to present a reconfiguration strategy for actuated tensegrity structures. The main idea is to use the infinitesimal mechanisms of the structure to generate a path along which the tensegrity can change its shape while maintaining the equilibrium.

Combining the force density method with a marching procedure, the solution to the equilibrium problem is given by a set of differential equations. Beginning from an initial stable position, the algorithm calculates a small displacement until a new stable configuration is reached, and recurrently repeats the process during a given interval of time.

By means of three numerical simulations and their respective experimental example, the efficacy of this algorithm for reconfiguring the well-known three-bar tensegrity prism along different directions is shown. The proposed method shows efficiency only for small changes of string length. Further work should consider the application of this method to more complex tensegrity structures.

The advantage of this reconfiguration method is its simplicity for finding new stable positions for tensegrity structures, and the fact that it doesn’t need the information of the material of the structure for the computations.

This paper aims to propose a study on the static behavior of prismatic tensegrity structures and an innovative form for determining the effect of mechanical properties and geometric parameters on the minimal mass design of these structures.

The minimal mass design in this paper considers a stable class-two tensegrity tower built through stable models. Using the proposed structures, comprehensive parametric studies are performed to examine the mass (in which the masses of joints are ignored), the mass ratio between a class-two tensegrity tower and a single element, both having the same diameter and length and afterward determine a reliable mass saving structure under various circumstances.

The simulations show that the mass ratio versus the number of units is a nonlinear regressive curve and predicts that the proposed model outperforms the standard model when the variation parameter considered is a vertical force. The difference in mass between these structures is visible when the gap gradually decreases while the number of units increases. On the geometrical aspect, the gap between the masses is not significant.

This paper helps to understand the influences of geometric parameters and the mechanical properties on the design of cylinder tensegrity structures dealing with a compressive force.

Additive manufacturing has disadvantages, such as the maximum part size being limited by the machine’s working volume. Therefore, if a part more considerable than the working volume is required, the part is produced in parts and joined together. Among the many methods of joining thermoplastic parts, adhesives and mechanical interlocking are considered. This study aims to characterize and optimize mechanically stressed adhesive joints combined with female and male mechanical interlocking on acrylonitrile butadiene styrene (ABS) specimens made with fused filament fabrication (FFF) so that the joint strength is as close as possible to the strength of the base material.

This study characterized the subject’s state of the art to justify the decisions regarding the experimental design planned in this research. Subsequently, this study designed, executed and analyzed the experiment using a statistical analysis of variance. The output variables were yield strength and tensile strength. The input variables were two different cyanoacrylate adhesives, two different types of mechanical interlock (truncated pyramid and cylindrical pin) and the dimensions of each type of mechanical interlock. This study used simple and factorial experiments to select the best adhesive and interlocking to be optimized using the response surface and the steep ascent method.

The two adhesives have no statistical difference, but they show different data dispersion. The design or yield stress was a determining factor for selecting the optimal specimen, with cylindrical geometry exhibiting higher resistance at initial failure. Geometry type is crucial due to the presence of stress concentrators. The cylindrical geometry with fewer stress concentrators demonstrated better tensile strength. Ultimately, the specimen with a mechanically reinforced joint featuring a cylindrical pin of radius 5.45 mm and height of 4.6 mm exhibited the maximum tensile and yield strength.

Previous research suggests that a research opportunity is the combination of bonding methods in FFF or fused deposition modeling, which is not a frequent topic, and this research to enrich that topic combines the adhesive with mechanically interlocked joints and studies it experimentally for FFF materials, to provide unpublished information of the performance of the adhesive joint with mechanical interlocking, to designers and manufacturers of this technology.

The purpose of this paper is to introduce the concept of socially responsible human resource management (SRHRM) and examine the reflection of SRHRM on sustainable development (SD) in Egyptian companies.

The study data was collected using a quantitative method to examine and test the relationship between the two variables. An empirical study was conducted between 2022 and 2023 on 150 samples of male and female employees from 18 companies located in Egypt working in castings and car batteries.

The study found that, in general, SRHRM has a significant impact on organizational sustainability. This contribution is also beneficial for general HRM and corporate social responsibility (CSR) literature as it stresses the importance of its relations to SD. By critically analyzing contemporary SRHRM literature, this study further demonstrates how studies with utilitarian approaches have dominated earlier research. By recognizing the necessity for process-oriented studies and the significance of critical scholarship within the field of SRHRM and its connections to the SD, the researcher thereby creates a research agenda for future studies.

The findings only apply to the sample that has participated in this study and to the Egyptian companies. A longitudinal quantitative evaluation of the SRHRM approaches and dimensions and their impact on the SD strategies of Egyptian companies would be recommended in terms of further research study, highlighting the role of SRHRM and its impact on achieving companies' CSR strategies.

The study's findings are helpful for firms looking to implement SR-HRM to enhance some employees' performance and promote organisational sustainability. In Egypt, there is a dire need for responsible leadership in the public and private sectors, which is crucial in the market and industry sectors. In addition to updating all policies, urge the younger generation to participate in them. For example, new hires to the company must demonstrate that they have engaged in volunteer work as part of their social obligation to the community, and this is required for recruitment.

Furthermore, refreshing all the policy encourage the young generation working or before working to take part in these policy, such as newcomers to the companies have to show that they have conducted some social responsibility towards their community as voluntary work. A study conducted by Cristina del-Castillo et al. (2022) confirmed that regarding the performance of different factors, the results show that the organizations under study are investing too much effort in improving CSR factors that are less relevant to achieving positive legitimacy assessments. On the one hand, resources destined to improve policies related to health, security and social benefits and those regarding the improvement of the relationship paths between managers and employees are excessive considering the relevance that they represent compared to the rest of the CSR policies. According to Hazzi and Maldaon (2023), stakeholders (including the general public and policymakers) might make an informed choice about how much organizations with CSR could safeguard their well-being if they had access to transparent CSR information. Talking about the sustainability behaviour of SRHRM as crucial for embedding sustainability in the business, a study by Abutaleb et al. (2021) evidence that subjective norms and attitudes, followed by perceived behavioural control and personal norms had the greatest influence on intentions towards behavioural HR. Attitudes towards sustainability practices were significantly influenced by economic advantages and sustainability. A good model fit was demonstrated by measurement and structural models (Abutaleb et al., 2021).

This paper is unique in that it participates in presenting the concept of the social responsibility of HRM as an intervention and approach for SD. It also participates in presenting unique findings related to Egyptian companies. There is a scarcity of literature related to research and studies on SRHRM in Egypt.

After completion of this case study, students will be able to describe the funding path for start-ups, including the amounts and profiles of the usual investors or sources of funds, according to the moment in their life cycle and the characteristics of the initiative; highlight the challenges faced by start-up founders in weak entrepreneurial ecosystems and risky institutional environments; and argue in favor of or against different modes and typical instruments of venture capital (VC) investments in the early stages of new businesses, each of them different regarding dilutions, valuation potential, depth of negotiations and term sheets.

Asistensi, a technology and telemedicine start-up founded in 2020 in Venezuela by three entrepreneurs (Andrés Simón González-Silén, Luis Enrique Velásquez and Armando Baquero), raised US$3m in less than a year in a seed round in which it attracted the attention of professional VC funds such as Mountain Nazca, Alma Mundi Ventures and 468 Capital. Everything was set for launching operations in Mexico and the Dominican Republic in April 2021. However, a series of difficulties led to higher expenditure than planned, prompting the entrepreneurs to seek additional capital. The decision on the financial instrument to be associated with the potential valuation and shareholder dilution figures has been posed as a dilemma.

The case study focuses on understanding the start-up financing process. It can be used effectively in management- and finance-related subjects for graduate students taking introductory topics in entrepreneurship and entrepreneurial finance, as well as introductory executive education courses in entrepreneurship, entrepreneurial finance and VC.

This study examines the effect of design quality (i.e. appearance, navigation, information and interactivity) on cognitive and affective involvement leading to continued intention to use the online learning application.

We assume that design quality potentially contributes to enhance the individual's involvement and excitement. An experimental prototype is developed for collecting data used to verify and validate the proposed research model and hypotheses. A partial-least-squares approach is used to analyze the data collected from the participants (n = 662).

Communication, aesthetic and information quality revealed to be strong determinants of both cognitive and affective involvement. However, font quality and user control positively influence cognitive involvement, while navigation quality and responsiveness were observed as significant indicators of affective involvement. Lastly, cognitive and affective involvement equally contribute to determining the continued intention to use.

This study will draw the attention of designers and practitioners towards the perception of users for providing appropriate and engaging learning resources.

Prevalent research in the online context is focused primarily on cognitive and utilization behavior. However, these works overlook the implication of design quality on cognitive and affective involvement.

The board structure (BS) is pivotal in modern corporate governance (CG). This study aims to investigate BS variables (BSIZE, BIND and chief executive officer [CEO] duality) and their correlation with risk-taking behavior indicators, enriching the understanding of how CG shapes financial institutions’ (FIs) decision-making in Pakistan.

By scrutinizing data from 67 financial entities listed on the Stock Exchange of Pakistan spanning from 2011 to 2022 through panel data regression techniques, the research emphasizes that BS holds a substantial influence over the risk tendencies exhibited by these firms.

Key findings suggest that board size has a positive influence, aligned with previous CG research. Smaller boards perform better and avoid excessive risk-taking, contrasting some negative relationship claims. More independent directors are recommended to curtail risk and financial disruption. Holding both CEO and chair roles reduces risk exposure, resonating with reputational and employment risk theory. It is essential to recognize that BS’s impact on risk-taking is nuanced and context-dependent.

Policymakers, scholars, practitioners and investors working in the market for financial companies might greatly benefit from the empirical findings of this study. Imposing mandates on FIs to uphold adequate capital reserves functions as a safeguard against unforeseen losses, thereby diminishing the probability of unwarranted risk-taking.

Prior studies in this domain predominantly focus on nonfinancial sectors. In addition, existing research often explores the relationship between BS and firm risk-taking solely within the banking sector, overlooking other FIs. This study contributes by using a comprehensive data set encompassing all types of FIs, thus extending the existing literature.

This article focusses on the hybrid strategy, a simultaneous combination of cost leadership and differentiation strategy. The study aims to examine the impact of hybrid strategy on firm performance through its anticipated positive effects on process and product innovation. In addition, we study the moderating role of adaptive capacity in the direct relationships of hybrid strategy with process and product innovation.

Structural equation modelling was used to analyse 1,842 Spanish firms with fewer than 250 employees. We randomly selected small and medium-sized enterprises (SMEs) operating in Spain from the Spanish Central Business Directory (2021) database. The overall sample design was based on stratified sampling.

We found that hybrid strategy is positively related to firm performance and to process and product innovation. Additionally, in firms implementing hybrid strategies, process innovation fostered firm performance. Finally, adaptive capacity strengthened the relationships of hybrid strategy with process and product innovation. This sheds light on how and when hybrid strategy is most effective in fostering SME performance.

We highlight that SMEs need to establish strategies that use diverse resources and capabilities and not just generate competitive advantage using one strategy (cost leadership or differentiation strategy). This requires an agile and flexible systems and structures.

Our research provides novel results by proposing the adoption of hybrid strategies instead of pure strategies (cost leadership and differentiation strategy) as a way for SMEs to survive during crises. Unlike “stuck in the middle” strategies, our study demonstrates the importance of hybrid strategies in a comprehensive model that links them to innovation and firm performance, with adaptive capacity being a determining factor.
