The magnetohydrodynamic (MHD) flow problems are important in the field of biomedical applications such as magnetic resonance imaging, inductive heat treatment of tumours, MHD-derived biomedical sensors, micropumps for drug delivery, MHD micromixers, magnetorelaxometry and actuators. Therefore, there is the impact of the magnetic field on the transport of non-Newtonian Carreau fluid in the presence of binary chemical reaction and activation energy over an extendable surface having a variable thickness. The significance of irregular heat source/sink and cross-diffusion effects is also explored.

The leading governing equations are constructed by retaining the effects of binary chemical reaction and activation energy. Suitable similarity transformations are used to transform the governing partial differential equations into ordinary differential equations. Subsequent nonlinear two-point boundary value problem is treated numerically by using the shooting method based on Runge–Kutta–Fehlberg. Graphical results are presented to analyze the behaviour of effective parameters involved in the problem. The numerical values of the mass transfer rate (Sherwood number) and heat transfer rate (Nusselt number) are also calculated. Furthermore, the slope of the linear regression line through the data points is determined in order to quantify the outcome.

It is established that the external magnetic field restricts the flow strongly and serves as a potential control mechanism. It can be concluded that an applied magnetic field will play a major role in applications like micropumps, actuators and biomedical sensors. The heat transfer rate is enhanced due to Arrhenius activation energy mechanism. The boundary layer thickness is suppressed by strengthening the thickness of the sheet, resulting in higher values of Nusselt and Sherwood numbers.

The effects of magnetic field, binary chemical reaction and activation energy on heat and mass transfer of non-Newtonian Carreau liquid over an extendable surface with variable thickness are investigated for the first time.

The purpose of this study is to understand whether increasing the number of sensory modalities being stimulated impacts consumers’ in-store emotional responses (i.e. in-store enjoyment and arousal), store image perception and brand attitude.

The study used a between-subjects experimental design to examine 551 individuals’ perceptions and emotional responses in four sensory modalities stimulation conditions (i.e. visual, visual-smell, visual-taste and visual-smell-taste). The study used virtual reality visualisation technology and psychophysiological measurements (i.e. skin conductance and facial expression) to improve the ecological validity of the study design.

The current study supports the importance of multisensory in-store atmospheric design. When increasing the number of sensory modalities being stimulated, more positive emotional responses and perceptions were recorded. Additionally, increasing the number of sensory modalities also increased perceived intensity, and perceived intensity mediate the relationship between the stimulation of multisensory modalities and perception.

The study is without its limitations. For instance, the scope of the study was limited by the exclusion of auditory and haptic stimulation, the lack of manipulation of sensory intensity and the absence of sensory congruency examination.

This study contributes to retail and marketing practices by providing evidence to assist the retail design of in-store sensory cues and customer experiences.

This research uses both self-reported measures and biometric measures to test the sole effect of sensory modalities being stimulated on consumer evaluation. To the best of the authors’ knowledge, this study is the first to examine store atmospheric designs with psychophysiological methodologies and an immersive, two-story-high, 180-degree-visual-field and dome-shaped display.

The purpose of this article is to show how consumers’ inferences of manipulative intent mediate the effects of in-store arousal on pleasure and approach behavior.

A qualitative study identifies arousal as a dimension of the store environment that may lead to inferences of manipulative intent. An experiment manipulating arousal tests the mediating effect of inferences of manipulative intent on the relationship of arousal with pleasure and approach behavior.

A qualitative study and the results of an experiment suggest that arousing store environments lead to negative outcomes when consumers infer that such environments are manipulative. The experimental study results show that high in-store arousal increases inferences of manipulative intent, which in turn negatively affect pleasure and approach behaviors. The results also indicate that the effects of in-store arousal on inferences of manipulative intent vary with age.

The study results recommend that practitioners carefully design their store environments, such that arousal they create does not lead consumers to believe that the environment is manipulative.

This article contributes to extant literature by emphasizing the crucial role of inferences of manipulative intent in the effects of in-store arousal.

This paper aims to investigate how the current size and structure of a branded product portfolio impacts new product performance for fast-moving consumer goods (FMCG), testing the long-standing proposition that extending a firm’s brand and product portfolio too far is a dangerous proposition that may damage the market performance of the firm’s new product launches.

Aspects associated with brand size and structure that may impact new product performance are operationalized along two key dimensions: within-category (scale) and cross-category (scope). The impact of the brand’s scale and scope on the sales performance of newly commercialized products by the brand is empirically investigated in the context of FMCG. Over 2,000 new products launched in 2009 and 2010 across 31 food and non-food FMCG product categories in the USA are included in the regression-based analysis.

The authors find strong evidence that brands with broader within-category scale and cross-category scope overall are associated with more successful new product introductions, and that these influences generally are driven more by increased product trial than by repeat or persistence. The authors argue that the higher new product performance observed for more established and proliferated brands may be attributed to advantages of firm product development abilities and product acceptance by the marketplace.

The current results serve to temper the strong cautions set forth in much of the marketing literature about the dangers of overextending the firm’s brand and product portfolio. These results also suggest that future research should be conducted to further understand more nuanced implications of how best to grow the scale and scope of the firm’s brand and product portfolio.

The purpose of this research paper is to report about an investigation on the relationship between knowledge acquisition and knowledge creation to find out whether knowledge acquisition can predict knowledge creation. The study measures the concept of knowledge acquisition through the faculty use of knowledge acquisition tools and reading knowledge sources while measuring the concept of knowledge creation through the faculty use of knowledge creation tools and publishing knowledge sources.

The population of the study is faculty members in the United Arab Emirates (UAE). The sample of the population consisted of 300 faculty members affiliated with 26 universities and colleges. Data was collected from the sample through questionnaire instrument. Stated hypotheses and Mathew’s theory of knowledge consumption–production correlation are tested and verified through correlation matrix and regression analysis.

Findings of the study revealed that the use of knowledge acquisition tools by faculty members has a positive effect on the use of knowledge creation tools and on publishing knowledge sources. Likewise, reading knowledge sources appeared to have a positive impact on the use of knowledge creation tools and publishing knowledge sources. Accordingly, the study confirmed the stated four hypotheses. Moreover, the results of the study supported the theory of knowledge consumption–production correlation and strongly confirmed the prediction of knowledge creation through the use of information and communication technology (ICT) tools for knowledge acquisition and reading knowledge sources.

Findings of the study appeal to the decision-makers and stakeholders of academic institutions to make effective investment in ICT facilities and knowledge sources to improve knowledge creation among faculty members.

Not many studies have investigated how knowledge acquisition can predict knowledge creation in the academic environment. This paper contributes to the understanding of the relationship between knowledge acquisition and knowledge creation in academic settings. Findings of the study can be an important reference for providing and improving knowledge sources, knowledge acquisition tools and knowledge creation tools in the academic environment.

The purpose of this study is to investigate the impulsive purchase of Generation Z of Muslim women on TikTok Shop. The primary attention in this stimulation investigation drives the impulsive buying between the Generation Z of Muslim women customers in Indonesia. This study provides valuable concept to help a company or cosmetic brand grow the marketing strategy for stimulating impulsive behaviour of Generation Z customers on TikTok Shop.

An online survey of 256 Muslim women consumers of the Generation Z was used to collect the data. Covariance-based structural equation modelling was applied to assess the five hypotheses.

The results of this study indicate that micro-celebrities post authenticity has a positive and significant relationship with utilitarian browsing. However, micro-celebrities post authenticity did not have a positive and significant relationship with hedonic browsing. This study also concludes that utilitarian browsing was found to have a positive and significant relationship with hedonic browsing. Finally, hedonic browsing was found to have a positive and significant effect on reminiscence impulse purchase intention and designed impulse purchase intention.

The primary limitation is the research sample that only consists of Indonesian TikTok Shop customers. Next, the researchers could examine the research model in several countries to expand its generalisation. The second one, this research does not consider the origin country of a cosmetic product. The future study must investigate the local and foreign cosmetics to see the preference and the differences in the impulsive purchase, especially for Z women generation customer. Third, this study quantifies the intention to buy impulsively so that the following research must investigate the ownership of the cosmetics product that has been bought before. Finally, the research only involves a quantitative research method. The future study must investigate with another approach, such as a qualitative method or mixed-method, in the impulsive purchase intention context.

A cosmetic company or marketer could maximise the authenticity, relevancy and attractive information that is posted by micro media social celebrities or media social influencers. Cosmetic companies or marketers must provide comprehensive information to satisfy customers’ browsing actions. Finally, besides the information related to the limited cosmetics product stock, discount and promotion as the effective strategy to stimulate the impulsive buying, the cosmetics marketing can use gamification, increasing the picture quality and equipping product descriptions, and making educational content.

The existence of TikTok Shop is increasing the number of cosmetics products and competitors because of product’s excessive availability in the market. In the social benefit context, the Generation Z Muslim women can purchase and use various cosmetics product available on TikTok Shop, but customers must be on guard by knowing the cosmetics material to prevent the healthiness. In addition, the existence of TikTok Shop and the impulsive purchases by the Generation Z Muslim women are also increasing the retailer or local cosmetics producer income.

This study is a contribution to consumer behaviour literature by raising the Stimulus–Organism–Response framework used in determining the factors influencing browsing and impulsive consumption of cosmetic products on TikTok Shop.

The purpose of this paper is to explore the determinants of effective teaching–learning (ETL) from students’ perspective in B-schools and build a model for the satisfaction of students of B-schools from teaching–learning processes.

The study employs the descriptive research design, and the cross-sectional data are collected through a structured questionnaire. Out of 320, 302 accurately filled questionnaires were used for the empirical analysis. The data are collected from the masters of business management (MBA) students. An exploratory factor analysis is applied to appraise factors appropriate for ETL. A confirmatory factor analysis is used to establish reliability and validity of the identified factors. Structural equation modeling (SEM) is applied to empirically test the proposed model for ETL.

The major findings of the current study are as follows: this paper identifies extracurricular activities (ECA), conducive environment (CE) and project work and practical exposure (PWPE) as the determinants of ETL in MBA Programs. These determinants have been identified individually; however, collectively authors do not find any other study that discusses them. This paper explores a suitable and apt model of ETL through the identified determinants of ETL (ECA, CE and PWPE). This is also a contribution of the paper, which has not been observed by the authors, in the literature.

The scope of the research can be enhanced to the all level of management students and colleges of all sorts can be taken.

Findings of this paper are a long-term plan with a futuristic vision. Determinants affecting ETL will help the administrators and faculty members at the MBA programs to realign their focus for the future.

This study determines three determinants (from the students’ points of view) for the effectiveness of the teaching–learning process in the management (MBA) programs. The determinants in this study are ECA, CE and PWPE. SEM is applied to test the model of ETL and to specify these three determinants (constructs). Decision makers for MBA programs can prudently use the model to bring about transformation in teaching–learning processes in business schools.
