For efficient magnetic field calculations in electrical machines, the hysteresis and losses in laminated electrical steel must be modeled in a simple and reliable way. The purpose of this paper is to investigate and discuss the potential of a simple complex‐permeability model.

A frequency dependent complex‐permeability model as well as a more detailed model (describing hysteresis, classical eddy current effects, and excess losses separately) are compared to single‐sheet measurements on laminated electrical steel. It is discussed under which circumstances the simple complex‐μ model is an adequate substitute for the more detailed model.

A satisfactory agreement of the simple complex‐μ model was found with both detailed model and measurements, improving with increasing frequencies. This is true not only for the effective permeability function, but holds also for the detailed H‐B characteristics (hysteresis).

It is demonstrated that the complex‐μ model is a reliable and convenient starting point for the estimation of flux distribution and losses in complicated magnetic core geometries.

The study aimed to explore the effects of mineral admixtures – especially limestone filler (LF), brick powder (BP) and ceramic powder (CP) – on the performance of self-compacting sand concrete (SCSC). It studies their effect on mechanical properties and mass loss when exposed to acidic solutions (H2SO4 5% and HCl 5%) over periods of 28, 90 and 180 days. The study seeks to develop SCSC technology by taking advantage of locally available sand resources.

Using an experimental design, the study explores different formulation parameters, including the use of silty sand (AS) and dune sand (DS) in fixed proportions, where AS constitutes 70% and DS 30% of the total sand content. The superplasticizer ratio (SP) and water-to-binder ratio (W/B) are constant with varying amounts of mineral additives. The study immerses SCSC samples in acidic solutions (5% H₂SO₄ and 5% HCl) for 28, 90, and 180 days to evaluate mass loss and mechanical properties. This endeavor to advance such concrete technology is motivated by the desire to incorporate sand concrete into the realm of self-compacting concrete technology while also harnessing the advantages of locally available sand resources, particularly dune sand, which is abundant in the southern regions of Algeria.

SCSC results with mineral additives showed enhanced resistance in both tensile and compression tests, indicating improved durability compared to the reference sample without additives. However, excessive proportions of BP (>60%) or CP led to exceptions in this trend An exception to this trend was observed when BP was added in proportions exceeding 60% or when CP, indicating potential limitations in some additive formulations. Overall, the research provides valuable insights into improving the performance and durability of SCSC through the strategic incorporation of mineral admixtures, contributing to advances in self-compacting concrete technology.

1 – Valorization of local materials and recycling of waste: DS, LF, BP and CP, which are available in great quantities in the south of Algeria; 2 – Combination, at the same time, of alluvial sand and dune sand as aggregate and LF, BP and CP as filler. 3 – Application of the design of experiments method methodology for the optimization of these elements of the new sand concrete studied. The new building material elaborated present indeed a technical, economic and environmental interest.

The rapid adoption of social media has resulted in a fundamental shift in the way communication and collaboration take place. While social media is recognized as an important marketing communication tool, it has become overlooked how social media marketing activities (user-generated and firm-generated content) influence brand equity creation in the higher education sector. Drawing from social identity theory, this study identifies how higher education institutions develop customer-based brand equity using social media marketing and social brand engagement, taking cross-comparison between high and low subjective norms.

A survey was used to collect data from a sample of 936 undergraduates of private higher education institutions in Sri Lanka and Vietnam. These data were gathered using purposive sampling, and in testing the hypothesis and structure among the variables, structural equation modeling was used to determine the relationship between the study variables.

For the conceptual framework, the authors found that the structural equation model complies with the empirical data. The structural equation model shows that social brand engagement mediates the relationship between user-generated content, firm-generated content and brand equity. Further, the subjective norms were found to moderate the relationship between user-generated content, firm-generated content and social brand engagement, highlighting that the lower the subjective norms the higher the influence on social brand engagement as students receive low pressure and influence from external parties.

The study was conducted at private higher education institutes in Sri Lanka and Vietnam. Future research could benefit from the perceptions of undergraduates in public higher education institutes. Future researchers could widen the diversity of service settings in the sample and replicate this investigation to discover if the results are consistent across the whole services sector.

The current research contributes to the services marketing and branding literature in the higher education context. The paper presents the crucial elements in building brand equity for higher education institutes to fill the existing gaps in higher education branding literature. The findings of the current study provide strategies to improve the higher education sector.

The purpose of this paper is to examine whistleblowing behavior in the accounting community (students and professionals) in an emerging economy – India.

Using a case-based approach, data were collected from 263 accounting students and 268 accounting professionals in India.

Using multivariate and univariate analyses of variance and logistic regressions, the authors provided evidence on how accounting students and professionals behave in a whistleblowing environment. Specifically, the authors found mixed results when comparing the behavior of accounting students and professionals in a whistleblowing scenario. All subjects reflected a more collectivist attitude, although professionals were more concerned about “fixing” the identified internal control problem (a “shared” problem). Both groups expressed a firm desire to collect more evidence against the likely fraudster.

In this era of global offshoring of services including accounting, the current study makes significant contributions to the accounting ethics literature and the accounting profession by analyzing whistleblowing behavior from an Indian perspective – a highly underrepresented area in the accounting ethics literature. The study aims to guide companies and investors in the US and elsewhere that do business in India.

While the accounting literature has plenty of research on whistleblowing in the Western world, there is a dearth of literature on whistleblowing in India. This paper is among the first to document whistleblowing behavior in India, a country that prides itself on its vast availability of English-speaking and technically sound accounting professionals.

This study aims to examine the metal pollution in coastal sediment in the Peninsular Malaysia.

Approximately 141 published studies were screened from 1,285 documents and reviewed to determine the existing pollution status in the coastal areas of Peninsular Malaysia and the metals under review were Pb, Hg, Cd, Ar, Cu, Zn, Cr and Ni. Sources of pollutants and their effect on biological systems, marine organisms and human health were addressed in this review as well as recommendation of heavy metal removal or remedies in short. Emphasis is placed on marine pollution, particularly on the toxic metal accumulation in biota.

This study has revealed the different concentrations of pollutants, low, moderately, and chronically contaminated areas from heavy metals and the consequences to aquatic ecosystem and indirectly to human health, since an increasing in the coastal developments in Peninsular Malaysia.

The purpose of this paper is to determine cause and effect relationship between foreign direct investment (FDI) and economic growth (gross domestic product (GDP) taken as proxy) for Brazil, Russia, India, China and South Africa (BRICS nations) individually for the period 1992-2013. Also, the study tries to explore the reasons behind the linkage between FDI and GDP by estimating a linear regression model consisting of both macro-economic and institutional variables.

Johansen cointegration technique followed by vector error correction model (VECM) and standard Granger causality test are employed to investigate the causal linkage between FDI and GDP. To delve into the reasons behind this linkage, an ordinary least square (OLS) technique is also applied to test the linear regression model consisting of net FDI inflows as dependent variable and nine macro- economic and institutional variables. Residual diagnostics is also conducted using Breusch-Godfrey Lagrange Multiplier test for diagnosing the problem of serial correlation, Breusch-Pagan-Godfrey test for examining heteroskedasticity and Jarque Bera test for verifying the normality of residuals.

The Johansen cointegration result establishes a single cointegrating vector (long run relationship) between FDI and GDP for India, China and Brazil. After proving a cointegration, VECM results revealed that there exists unidirectional long run causality running from GDP to FDI in case of Brazil, India and China. Also, it is confirmed that there exists short run causality between FDI and GDP in China, i.e. the past lags of FDI jointly impact the value of GDP. However, for Russia and South Africa, where there is no cointegration in the long run, standard Granger causality test is conducted which reveals that in both the nations, FDI and GDP are independent of one another. The results of OLS technique reveal different country-specific factors causing this linkage between FDI inflows and economic growth.

Various researchers in the past have examined this issue of linkage between FDI and GDP in the context of various developing or developed nations. This reveals a gap in the existing literature pertaining to this causal linkage in the context of the BRICS. Thus, this study fills this gap by analyzing not just this causal nexus with the help of VECM and Granger causality techniques but also tries to explore further the reasons for such strong/weak/no link with the help of fitting a regression model which comprises of both macro-economic and institutional country-specific variables influencing this causation.

Drawing on the UTAUT-2 model, the study attempts to accentuate the role of augmented reality (AR) and virtual reality (VR) based tourism products and services in enhancing responsible travel behaviour (RTB). This paper aims to examine the emergence of AR- and VR-based tourism in emerging economies, outlines the issues and contributing factors and discusses possible mitigation measures.

Following the triangulation method of research, a dual study involving both focus group discussions and questionnaire-based surveys were undertaken. The grounded theory approach was adopted to develop a structural framework followed by an empirical validation process.

Critical dimensions such as performance anticipation, effort anticipation, referent power, facilitating factors, perceived value and perceived risk were found as antecedents of behavioural intentions (BIs) towards adopting AR- and VR-based tourism products. Moreover, cultural involvement and marketing stimuli emerged as moderating factors driving the BI towards RTB.

This paper outlines key elements that contribute to the adoption of AR- and VR-based tourism products and services in emerging economies, which would enable marketers and practitioners to strategize their tourism offerings.

The study takes a dual perspective of both tourists and tour operators and presents a critical overview of the AR- and VR-based tourism industry, taking an emerging economies’ perspective. The study further attempted both the triangulation method and grounded study approach for establishing a hypothetical framework, which is a unique attempt in itself.
