Abstract

Purpose

Confronting the unveiled sophisticated structural and physical characteristics of permanent magnets, notably the samarium–cobalt (Sm-Co) alloy, This work aims to introduce a simulation scheme that can link physics-based micromagnetics on the nanostructures and magnetostatic homogenization on the mesoscale polycrystalline structures.

Design/methodology/approach

The simulation scheme is arranged in a multiscale fashion. The magnetization behaviors on the nanostructures examined with various orientations are surrogated as the micromagnetic-informed hysterons. The hysteresis behavior of the mesoscale polycrystalline structures with micromagnetic-informed hysterons is then evaluated by computational magnetostatic homogenization.

Findings

The micromagnetic-informed hysterons can emulate the magnetization reversal of the parameterized Sm-Co nanostructures as the local hysteresis behavior on the mesostructures. The simulation results of the mesoscale polycrystal demonstrate that the demagnetization process starts from the grain with the largest orientation angle (a) and then propagates to the surrounding grains.

Research limitations/implications

The presented scheme depicts the demand for integrating data-driven methods, as the parameters of the surrogate hysteron intrinsically depend on the nanostructure and its orientation. Further hysteron parameters that help the surrogate hysteron emulate the micromagnetic-simulated magnetization reversal should be examined.

Originality/value

This work provides a novel multiscale scheme for simulating the polycrystalline permanent magnets’ hysteresis while recapitulating the nanoscale mechanisms, such as the nucleation of domains, and domain wall migration and pinning. This scheme can be further extended to simulate the part-level hysteresis considering the mesoscale features.

Abstract

Purpose

The purpose of this study is to explore numerical scrutinization of micropolar and Walters-B non-Newtonian fluids motion under the influence of thermal radiation and chemical reaction.

Design/methodology/approach

The two fluids micropolar and Walters-B liquid are considered to start flowing from the slot to the stretching sheet. A magnetic field of constant strength is imposed on their flow transversely. The problems on heat and mass transport are set up with thermal, chemical reaction, heat generation, etc. to form partial differential equations. These equations were simplified into a dimensionless form and solved using spectral homotopy analysis method (SHAM). SHAM uses the basic concept of both Chebyshev pseudospectral method and homotopy analysis method to obtain numerical computations of the problem.

Findings

The outcomes for encountered flow parameters for temperature, velocity and concentration are presented with the aid of figures. It is observed that both the velocity and angular velocity of micropolar and Walters-B and thermal boundary layers increase with increase in the thermal radiation parameter. The decrease in velocity and decrease in angular velocity occurred are a result of increase in chemical reaction. It is hoped that the present study will enhance the understanding of boundary layer flow of micropolar and Walters-B non-Newtonian fluid under the influences of thermal radiation, thermal conductivity and chemical reaction as applied in various engineering processes.

Originality/value

All results are presented graphically and all physical quantities are computed and tabulated.

Abstract

At the beginning of the 21st century, multiple and diverse social entities, including the public (consumers), private and nonprofit healthcare institutions, government (public health) and other industry sectors, began to recognize the limitations of the current fragmented healthcare system paradigm. Primary stakeholders, including employers, insurance companies, and healthcare professional organizations, also voiced dissatisfaction with unacceptable health outcomes and rising costs. Grand challenges and wicked problems threatened the viability of the health sector. American health systems responded with innovations and advances in healthcare delivery frameworks that encouraged shifts from intra- and inter-sector arrangements to multi-sector, lasting relationships that emphasized patient centrality along with long-term commitments to sustainability and accountability. This pathway, leading to a population health approach, also generated the need for transformative business models. The coproduction of health framework, with its emphasis on cross-sector alignments, nontraditional partner relationships, sustainable missions, and accountability capable of yielding return on investments, has emerged as a unique strategy for facing disruptive threats and challenges from nonhealth sector corporations. This chapter presents a coproduction of health framework, goals and criteria, examples of boundary spanning network alliance models, and operational (integrator, convener, aggregator) strategies. A comparison of important organizational science theories, including institutional theory, network/network analysis theory, and resource dependency theory, provides suggestions for future research directions necessary to validate the utility of the coproduction of health framework as a precursor for paradigm change.

Abstract

Purpose

The purpose of this study is to investigate the Dynamics of micropolar – water B Fluids flow simultaneously under the influence of thermal radiation and Soret–Dufour Mechanisms.

Design/methodology/approach

The thermal radiation contribution, the chemical change and heat generation take fluidity into account. The flow equations are used to produce a series of dimensionless equations with appropriate nondimensional quantities. By using the spectral homotopy analysis method (SHAM), simplified dimensionless equations have been quantitatively solved. With Chebyshev pseudospectral technique, SHAM integrates the approach of the well-known method of homotopical analysis to the set of altered equations. In terms of velocity, concentration and temperature profiles, the impacts of Prandtl number, chemical reaction and thermal radiation are studied. All findings are visually shown and all physical values are calculated and tabulated.

Findings

The results indicate that an increase in the variable viscosity leads to speed and temperature increases. Based on the transport nature of micropolar Walters B fluids, the thermal conductivity has great impact on the Prandtl number and decrease the velocity and temperature. The current research was very well supported by prior literature works. The results in this paper are anticipated to be helpful for biotechnology, food processing and boiling. It is used primarily in refrigerating systems, tensile heating to large-scale heating and oil pipeline reduction.

Originality/value

All results are presented graphically and all physical quantities are computed and tabulated.

Abstract

Purpose

This study examines the effect of face on consumer responses to socially responsible hospitality brands and the influence of the consumption setting. Based on the literature on face concern, the consumption setting is expected to influence the effect of face on consumer responses to socially responsible brands.

Design/methodology/approach

An experimental design with face concern (low vs high) under two consumption settings (private vs public) was adopted for a fictitious hotel involved in community service. To test this design, 360 participants were recruited.

Findings

The results showed that face positively affected consumer responses to socially responsible hospitality brands. Consumers with a high (vs low) level of face concern had higher purchase intention and a greater propensity to spread positive word-of-mouth for hospitality brands with strong corporate social responsibility (CSR) associations. In addition, the favorable effect of face concern on consumer responses was more pronounced in a public consumption setting than in a private consumption setting.

Practical implications

Hospitality service managers could strengthen the physical evidence of CSR brands during service encounters. This strategy would be more effective for consumers who have a high level of face concern and lead to an increase in revisit intention.

Originality/value

This study highlights the effect of face on consumer responses to CSR brands and the influence of the consumption setting. Managerial implications for hospitality service managers regarding communication and brand management strategies are discussed.

Abstract

Purpose

The recent pandemic disrupted the way in which businesses transact with each other. In response to maintaining cleanliness in business-to-business (B2B) settings, artificial intelligence (AI)-enabled robots have been adopted as substitutes for cleaning personnel, yet their implications remain largely underexamined. This study aims to examine B2B buyer responses to cleaning information notices (human vs AI-enabled agent) placed at either the entry to the premises or the sales counter, thereby adding to the nascent literature in this line of inquiry.

Design/methodology/approach

Three field experiments were conducted across diverse B2B businesses (wholesalers in Studies 1–2 and a commercial business in Study 3). To achieve greater empirical rigor and generalizability, this research used diverse stimuli across different B2B settings. In addition, the results ruled out alternate explanations and shed light upon political ideology as a boundary condition. Finally, a single-paper meta-analysis confirmed H1, consolidating the established effect.

Findings

Featuring over 1,000 B2B buyers, the results show that politically liberal B2B buyers express greater preference for human over AI-performed cleaning while labor-orientated buyers are indifferent. Importantly, this effect is driven by greater relaxation associated with humans, which in turn, increases their future patronage and referral intent.

Originality/value

The results enrich the collective knowledge of the adoption of AI-enabled robots, reinforcing for marketing practitioners and businesses that the reliance on human-based outcomes remains a preferred touchpoint in B2B settings, particularly for liberals.

Abstract

The role of financial institutions and financial intermediaries in fostering economic growth (ECO) by improving the efficiency of capital accumulation, encouraging savings, and ultimately improving the productivity of the economy has been well established by the researchers. The reforms in the financial sector worldwide during the 1980s and 1990s were aimed at ushering in greater efficiency and more competitiveness.

The impact of financial market freedom (MF) on the overall development of the financial sector and thereby the growth in an economy is one of the most important considerations for policymakers over the years. This chapter aims to examine the causal relationship between financial MF and ECO in the Indian economy in the post-reform period.

Abstract

Purpose

Prisoners with substance use disorder (SUD) are at risk of mental health problems. Given the common co-occurring of psychopathic traits with SUDs, probably because of underlying impulsive traits (Ellingson et al., 2018), this study aims to examine the relation between psychopathy (impulsive antisociality and fearless dominance) and the functioning of incarcerated individuals with SUD. The authors investigated whether impulsivity (motor, nonplanning and attentional) can account for the relationship between one psychopathy facet (impulsive antisociality) and craving and mental health problems.

Design/methodology/approach

The authors assessed self-reported impulsivity, psychopathy, craving and mental health problems in 121 male incarcerated individuals with SUD and calculated cross-sectional linear regression analyses and mediation models.

Findings

Impulsive antisociality was positively related to all impulsivity facets, craving and mental health problems. Attentional impulsivity mediated the relationship of impulsive antisociality with craving and mental health problems. Fearless dominance was related to lower attentional and nonplanning impulsivity, craving and mental health problems.

Research limitations/implications

Future studies should investigate these relations in longitudinal studies and evaluate tailored approaches, for example, mindfulness interventions.

Practical implications

Interventions to reduce craving and improve mental health might be important for those who display self-centered, antisocial behavior but are less relevant for those with fearless, dominant interpersonal behavior. Addressing attentional impulsivity may be of special interest in this regard.

Originality/value

To the best of the authors’ knowledge, this study was the first to investigate the mediating role of different impulsivity facets for the association of impulsive antisociality with craving and with mental health problems in incarcerated individuals with SUD.

Abstract

Purpose

There is evidence of country-level contextual variations regarding the benefits of practical experience acquired by students during higher education. This paper, therefore, analyses the benefits of student internships in the Ghanaian context.

Design/methodology/approach

In Study 1, two structured but distinct surveys were distributed to senior members and students of six specialised technical education institutions (TIs). Study 2 involved in-depth interviews with the heads of organisations in the tertiary education sector, including trade groups, industries and government agencies.

Findings

Internship provides soft skills, confidence, career development, sense of responsibility, employability, income, knowledge sharing and networking for students/interns. For TIs, it contributes to the professional development of faculty supervisors and helps them to update the content they teach. For employers, it unveils talented and promising students who can be employed immediately after graduation at a relatively cheaper cost.

Research limitations/implications

There is still the need for additional research in different contexts: both developed and developing economies to clear doubts on the controversies surrounding the relevance of internship in the 21st century.

Practical implications

TIs should continue to champion student internship programmes. This study highlights the need for employers to place internship students in areas that relate to their fields of study. It also underscores the need for students to embrace internship since it is the cornerstone to their employability in the labour market.

Social implications

Undeniably, student internships provide a critical platform for career beginners.

Originality/value

This paper contributes to knowledge by offering contextual literature in Ghana on the benefits of student internship programme for interns/students, TIs and employers, all together.

Abstract

Purpose

Expressions of pride may elicit others’ envy. In the consumer context, prior research has repeatedly demonstrated that such envy significantly affects consumers’ attitudinal and behavioural responses towards the object of envy. This paper aims to investigate whether this pride-envy relationship is bi-directional. Does being envied by others affect consumers’ self-directed feelings of pride, as well as their subsequent attitude towards a product (i.e. the object of envy)?

Design/methodology/approach

Three experiments examined how emotional reactions of envy from others may influence consumers’ subsequent affective and attitudinal responses towards their own product or purchase. The first experimental study (n = 129) examined whether exposure to benign envy from others evokes higher levels of authentic pride and positively influences product attitude. The second experiment (n = 159) investigated whether exposure to malicious envy from others evokes high levels of hubristic pride, and therefore, negatively influences product attitude. The third study (n = 80) was a quasi-field experiment seeking to provide further empirical support for the relationship between benign (vs malicious) envy and authentic (vs hubristic) pride and their effects on attitude.

Findings

The first experiment showed that when participants observed expressions of benign envy towards them, they expressed authentic pride, which ultimately increased positive attitudes towards the product. The second experiment showed that when participants observed expressions of malicious envy towards them, they expressed hubristic pride, which, in turn, reduced positive attitudes towards the product. The effect of malicious envy was further moderated by susceptibility to social influence, whereby the indirect effect of malicious envy on product attitudes was only significant among participants with high susceptibility. The third experiment demonstrated the relationship between benign (vs malicious) envy and authentic (vs hubristic) pride and the effects on attitude in a quasi-field study.

Research limitations/implications

The present paper aims to fill a research gap by showing how being the recipient of others’ malicious or benign envy affects consumers’ self-directed feelings of pride, as well as their attitude towards a product that is the object of envy.

Practical implications

The current research is among the first to show that the emotional expressions of other consumers can influence existing consumers’ affective responses and attitudes towards a product. These findings highlight the importance of building a positive culture and community around brands and products, whereby other consumers’ consumption of the brand or product is perceived positively.

Originality/value

To the best of the authors’ knowledge, this study is the first empirical evidence demonstrating that others’ expression of benign (malicious) envy may lead to the self-feeling of authentic (hubristic) pride, which has a downstream effect on attitude towards the product.
