Abstract
Purpose
This study aims to characterize a novel glass/epoxy architecture sandwich structure for electronic boards. Understanding the thermo-mechanical behavior of these composites is important because it is possible to pre-determine whether defined “internal” thick laminates will be suitable for embedding components in the direction of the axis “z,” i.e. this method of manufacturing multilayer laminates can be used for incoming miniaturization in electronics.
Design/methodology/approach
Laminates with a low glass transition temperature (Tg) and high Tg with E-glass type were treated, tested and compared. Testing samples were manufactured by nonstandard two steps unidirectional lamination as a multilayer structure based on prepreg layers and as “a sandwich structure” to explore its effect on thermo-mechanical properties. The proposed tested method determines the time and temperature-dependent viscoelastic properties of the board by using dynamic mechanical analysis, thermo-mechanical analysis and three-point bend tests.
Findings
This testing method was chosen because the main property that promotes sandwich structure is their high stiffness. Glass/epoxy stiff and thermal stabile sandwich structure prepared by nonstandard two-stage lamination is proper for embedding components and the next miniaturization in electronics.
Originality/value
Compared with by-default applied glass-reinforced homogenous laminates, novel architecture sandwich structure is attractive because of a combination of strength, stiffness and all while maintaining the miniaturization requirement and multifunctional application in electronics.

Abstract
Purpose
This paper examines the moderating role of firm size (FS) and industry type in the relationship between high-performance work practices (HPWPs) and entrepreneurial firm performance.
Design/methodology/approach
A descriptive research design involving a five-year dataset from firms in the retail and services industries of Nigeria was used in the analyses.
Findings
The use of HPWPs is widespread among entrepreneurial firms, with ability- and motivation-enhancing practices being dominant. Country context influences the types of HPWPs implemented by entrepreneurial firms. FS and industry type do not have significant moderating effects on the relationship between HPWPs and the performance of entrepreneurial firms. The positive effect of HPWPs on performance is consistent with findings made in prior studies.
Research limitations/implications
FS plays a neutral role in the relationship between HPWPs and entrepreneurial firm performance. Within the broader retail and services industries, this relationship is weaker in capital-intensive firms compared to less capital-intensive ones. The restricted focus on only retail and service industries may limit the universal applicability of the findings.
Practical implications
Findings indicate that the efficacy of HPWPs is neither influenced by FS nor industry type. Entrepreneurial firms with higher capital intensity benefit relatively more from the use of HPWPs.
Originality/value
Unlike other research efforts focusing on a single moderating influence, this study combines two important contextual factors, FS and industry type, to provide a better understanding of HPWPs. The study spotlights the effects of country context in the implementation of HPWPs in a way that prior studies have not done.

Abstract
Purpose
The impact of technological transformations in all sectors is undeniably significant, especially in fitness family business. The aim is to examine the digital transformation perceptions of fitness centre employees and the effects of perceived empowerment on their job performance in family business in Turkey.
Design/methodology/approach
The sample was 334 fitness centre employees. Four variables were evaluated (digital transformation, meaning competence, self-determination and job performance), and PLS-SEM was used.
Findings
The digital transformation process in the fitness sector can be considered as an important factor in terms of creating new business ventures. Our results showed that digital transformation perceived by family business employees had a significantly influence on the meaning competence of the employees. Also, the meaning competence of employees was a mediator between the digital transformation and job performance.
Practical implications
Managers of family businesses must take into account that an appropriate digital transformation of their products and/or services has an impact on the meaning competence of their employees. Thus, through increased competence in employee performance, the digitization of family business fitness will lead to higher employee performance and productivity.
Originality/value
This study innovates by linking digital transformation as a factor influencing the coach's own motivation and self-perceived competence in the use of technology to their job performance.
