Abstract

Purpose

The paper aims to study the friction behaviour of alumina and zirconia against steel DIN‐Ck45K under water lubricated conditions.

Design/methodology/approach

The tests were performed with a contact stress of 3.5 MPa and a constant sliding velocity of 0.5 m/s for 5.35 km of sliding distance, using a pin‐on‐disk tribometer.

Findings

The friction coefficient and the energy dissipated in the contact were considered in this comparative study. The zirconia ceramic present less friction coefficient and contact temperature than alumina ceramic. The zirconia present about 70 per cent of the energy dissipated against when compared with the alumina. Abrasive scars of the surface ploughing were observed on every wear track for two pairs in contact.

Research limitations/implications

This research used only one test condition.

Originality/value

The paper describes the tribological conditions used and a new methodology based on the energy dissipated in the contact is proposed.

Abstract

Purpose

The purpose of this paper is to explore the disparities in social awareness and use of the internet between urban and rural school children in the North of Vietnam.

Design/methodology/approach

A total of 525 pupils, aged 9-11 years old, randomly selected from seven urban and rural schools, who are internet users, participated in the study and consented to responding to a questionnaire adapted from an equivalent European Union study. A comparative statistical analysis of the responses was then carried out, using IBM SPSS v21, which consisted of a descriptive analysis, an identification of personal self-development opportunities, as well as issues related to pupils’ digital prowess and knowledge of internet use and internet safety, including parental engagement in their offspring’s online activities.

Findings

The study highlights the fact that children from both the urban and rural regions of the North of Vietnam mostly access the internet from home, but with more children in the urbanized areas accessing it at school than their rural counterparts. Although children from the rural areas scored lower on all the internet indicators, such as digital access and online personal experience and awareness, there was no disparity in awareness of internet risks between the two sub-samples. It is noteworthy that there was no statistically significant gender difference towards online activities that support self-development. In relation to safe internet usage, children are likely to seek advice from their parents, rather than through teachers or friends. However, they are not yet provided with an effective safety net while exposing themselves to the digital world.

Originality/value

Although the Vietnamese national curriculum on the computer science subject does not explicitly cover the use of the internet and its related aspects, the majority of children who took part in this study claimed to have used the internet in their learning activities. This emphasises the urgent need for the Ministry of Education and educators in the country to not only improve information and communication technology facilities in schools, but also to revise the computer science curriculum in order to provide a supportive environment for learning development and collectively advocate the dynamics of internet use in order to ensure safe access and use by the children.

Abstract

Purpose

The purpose of this paper is to examine the influence of human resource management (HRM) reforms on job-related well-being of academics in Chinese universities. It also tests the mediating effect of work intensification (WI) and affective commitment (AC), and the moderating effect of perceived organizational justice (OJ) on the HRM‒well-being relationship to understand the influence mechanisms and boundary conditions.

Design/methodology/approach

A questionnaire survey was conducted in 25 Chinese universities, obtaining 638 usable questionnaires. Structural equation modeling (SEM) was used as the analytical technique to examine the model fit and test hypotheses.

Findings

The findings reveal that the relationship of HRM and well-being is neither direct nor unconditional, and a win‒win scenario for both management and employee well-being is possible when organizations pursue HRM innovations.

Research limitations/implications

The limitations of this study are that data were collected at once and at a defined time, with no time lag being involved. In addition, all variables were self-reported.

Practical implications

Commitment-oriented HRM practices can create a win‒win scenario; when control-oriented HRM practices are necessary, managers should ensure OJ to offset their negative influence on employees.

Originality/value

This study is among the first to examine the impact of HRM on employee well-being in the context of Chinese higher education, contributing to the limited studies on HRM in Chinese public sector and the on-going debate on the nature of HRM in China.

Abstract

Purpose

International entrepreneurship (IE) has received a considerable amount of attention in the recent decades as a result of globalization enabling access to new international markets and business opportunities. Despite the growing increase in academic publications, IE still faces certain inconsistencies, with doubts remaining as regards its boundaries and the thematic groups making up the field. The purpose of this article is to systematically analyse the IE, mapping the intellectual territory and the evolution of the field.

Design/methodology/approach

Indexed to Web of Science( WoS) database until 2021, from 52 journals, 130 articles were selected, applying content analyses techniques to identify the main research lines.

Findings

The results reveal that IE presents four conceptual themes/clusters: (1) international business networks and opportunities; (2) institutional environments; (3) the characteristics and motivations of entrepreneurs; and (4) internationalisation drivers and processes. Extant analysis show that IE has progressed immensely, concentrating a good diversity of subtopics and research trends. An integrative framework bringing together 27 years of publications and 67 future research lines, detailed by cluster, were also presented in this study to improve understanding and guide future studies.

Originality/value

This review makes a broad contribution to the IE literature, assisting in consolidating the academic field, expanding and complementing the results of previous theoretical–conceptual studies. We reflect and individually discuss the state of the art of the four streams that characterize IE to identify key themes, points of convergence and advance new subfields.

Abstract

Purpose

Entrepreneurship is a phenomenon strongly associated with economic growth, development and employability, leading countries to compete and often produce reforms to ensure good levels of entrepreneurship. In this sequence, this study aims to know which types of economies present favourable institutional environments for entrepreneurs, exploring the link between the ease of doing business and the three levels of economic development (innovation-driven, efficiency-driven and factor-driven) of 137 economies.

Design/methodology/approach

A quantitative methodology through an analysis of variances was adopted, gathering data from the ten pillars proposed by the World Bank in the Doing Business 2019 – training for reforms report, and economic development levels, provided by Global Competitiveness Report (2017–2018).

Findings

In the light of institutional theory, the results showed that innovation-driven economies are more competitive, presenting more robust institutional environments for entrepreneurs than factor-driven and efficiency-driven. There is only one exception in the Getting Credit pillar.

Originality/value

This study clarifies some assumptions in the previous literature that developed economies have better business environments, being the first one to establish this relationship directly. Some practical implications, especially for international entrepreneurs in the decision-making phase on which type of economies to carry out their investments and policymakers and researchers, were provided in this study.

Abstract

Purpose

This study explores how strategic human resource practices enhance the competitive capability of differentiation and cost-effectiveness by leveraging knowledge resources in Indian IT/software organizations. It examines the mediating effect of knowledge management (KM) processes in the relationship between strategic HR practices, competitive differentiation and cost-effectiveness capabilities.

Design/methodology/approach

An online questionnaire survey collected data from 380 knowledge workers in 25 IT/software and consultancy firms. The authors checked data reliability and validity by conducting exploratory factor analysis in SPSS and confirmatory factor analysis in AMOS. The authors evaluated hypotheses using path analysis in structural equational modeling in AMOS.

Findings

Strategic HR practices significantly and positively affect KM processes and competitive capabilities-differentiation and cost-efficiency. Both strategic HR practices and KM processes have a closer association with differentiation than cost-effectiveness. Knowledge management processes significantly and positively mediate between strategic HR practices and competitive capabilities. The mediation is more substantial in predicting differentiation than cost-effectiveness.

Research limitations/implications

It is a cross-sectional study with a constrained capacity to predict accurate causal inferences; The authors call for future studies with longitudinal design and objective measures. Further studies are required to explore the impact of various strategic HR configurations on KMP to understand how different routes stimulate a particular competitive strategy. This conceptual framework can be validated across different industry types and sizes.

Practical implications

This study provides practical insights to HR and knowledge managers regarding devising HR and KM processes to accomplish the goals of differentiation and cost-effective, competitive strategies. This study highlights that leveraging human capital for effective KM is crucial for gaining a competitive advantage.

Originality/value

The paper adds to the strategic HR and KM literature by exploring the mediating role of KM processes in enabling strategic HR processes to enhance differentiation and cost-effective, competitive strategies. It provides original empirical evidence from knowledge-intensive IT/software consultancies, particularly in India's emerging economy. It indicates the current state of HR practices adopted for optimum utilization of knowledge resources and the importance of differentiation strategy for Indian knowledge-intensive IT/software firms.

Abstract

This book aimed to conceptualise a construction workforce management model suitable for effectively managing workers in construction organisations. To this end, this chapter presents the conceptualised model, which consists of seven workforce management practices with their respective measurement variables. Drawing from existing theories, models, and practices, the chapter concludes that a construction organisation that will attain its strategic objectives in the current fourth industrial revolution era must be willing to promote effective recruitment and selection, compensation and benefits, performance management and appraisal, employee involvement and empowerment, training and development, as well as improving workers emotional intelligence and handling external environment pressure. These practices can promote proactiveness, participation, and improved skills and can lead to effective commitment, better quality, and flexibility within the organisation.

Abstract

Purpose

Celebrity-branded products constitute a brand extension growing phenomenon. Authenticity may explain why some of these offerings are successful despite low perceived fit, a traditional measure for brand extension acceptance. The purpose of this paper is to propose and test a framework based on the meaning transfer model that depicts the effects of brand extension authenticity, brand extension fit and idol attachment on the valuation of such offerings. An exploration of both functional and hedonic extensions is provided to control for product-type variables.

Design/methodology/approach

Scenario-based survey data from a general population (n = 646) was collected and analyzed with ordinary least squares regressions.

Findings

Brand extension authenticity is a significant antecedent of brand extension success in both product types, and brand extension fit is the most relevant antecedent only in functional extensions. Idol attachment exerts less influence than fit and authenticity in the functional extension. However, its relevance considerably improves in the hedonic extension.

Originality/value

A better understanding of consumers’ responses to celebrity brand extensions is essential to the branding literature. To the best of the authors’ knowledge, this study is the first to consider brand extension authenticity as a predictor of celebrity brand extension success and advances our knowledge of consumer behavior in relation to celebrities as brands and their products as brand extensions. The conceptual and empirical relevance of brand extension authenticity is demonstrated, highlighting its predictive power when compared with brand extension fit and idol attachment in a celebrity brand extension model, and a boundary condition related to product typology is uncovered.

Abstract

The South Texas University this study examined is a Hispanic Serving Institution (HSI) that has a 73.3% Hispanic (primarily Mexican American) population (Tallant, 2018 ). The logical consequence of education is the provision or guarantee of an equitable opportunity for all students to have equal access to learning and the achievement of academic success (Stewner-Manzanares, 1988 ). The basic definition of bilingual education in the United States is the use of two languages for instruction of the home language and English. Unfortunately, this basic principle is not accepted by postsecondary institutions as predispositions of university preparedness (Blanchard & Muller, 2014; García, Kleifgen, & Falchi, 2008; Kanno & Cromley, 2013; Lee et al., 2011; Menken, Hudson, & Leung, 2014). Mexican American students are potentially being left out of the opportunities afforded by the attainment of a postsecondary education because they are a language minority (Lucas, Henze, & Donato, 1990; Moll, 1990; Trueba, 2002; Trueba & Wright, 1981; Washington & Craig, 1998). Students are already examined for postsecondary credentials or college readiness, in the eighth grade (Paredes, 2013). Through this testing, 11 out of every 100 Hispanic children in the state of Texas are deemed as having attained postsecondary credentials (Paredes, 2013). As part of the fastest growing demographic group in Texas and the United States, the Mexican American population holds the lowest rate of graduation from postsecondary institutions and the highest high school dropout rate of any ethnic minority in the nation. In a 12-year study, Kanno and Cromley (2013) found that one out of eight English as a second language (ESL) or English language learners (ELLs) attain a bachelor’s degree from postsecondary institutions across the United States while the success rate for their English, monolingual counterparts is one out of three. Various researchers (García et al., 2008; García, Pujol-Ferran, & Reddy, 2012) argue that the inequity of education in the United States can be measured by how few minority students educated under the principles of education attend a postsecondary institution because it is the diploma from such institutions that leads to higher paying wages for the individual (García, 1991; García et al., 2008, García et al., 2012).
