Abstract

Purpose

The purpose of this paper is to analyze the flowfield structure and performance of dual secondary injection system for thrust vectoring in a convergent‐divergent nozzle and to compare it with a single secondary injection system.

Design/methodology/approach

Dual secondary injection for thrust vectoring in a convergent‐divergent nozzle is studied by solving three‐dimensional Reynolds‐averaged Navier‐Stokes equations by the means of Fluent. Realizable k‐ε turbulent model with enhanced wall‐treatment approach is used for viscous model. Density‐based solver and explicit scheme are employed in the computational model. In order to study the effect of injection location on the flowfield, distance between ports is considered as the key variable.

Findings

Results show that under some circumstances, dual secondary injection system is more effective than a single injection system with the same mass flow rate. The study shows that when the distance between two ports is 8.5 times of the injection port's diameter (or more) and in the same time the first injection port is at least 1 throat diameter far from the nozzle throat, this system will show a better performance. In addition, this system reduces the probability of bow shock impingement to the opposite wall and consequently, the side force production has less limitation.

Practical implications

Dual secondary injection for thrust vector control (SITVC) needs less secondary flow and therefore it makes less reduction in the primary thrust. It means that for a specific primary thrust, less mass fuel is needed which makes it more economic regarding the traditional SITVC systems.

Originality/value

The paper's value lies in using a three‐dimensional model to study the effect of two ports distance on SITVC performance and comparison among the performance of dual and single injections when there is an impingement.

Abstract

Purpose

The purpose of this paper is to present a conceptual model that intends to identify the determinants and consequences of brand credibility, specifically in the pharmaceutical industry.

Design/methodology/approach

The hypotheses developed according to the proposed model were tested through an online questionnaire and answered by 225 individuals from Portugal.

Findings

The results show that the credibility of brand communication, perceived quality and brand familiarity are the key components that contribute most to the creation of a credible brand. Regarding consequences, this study confirms that, in the face of a credible brand, consumers are more willing to repeat the purchase, to pay more for it and to promote their opinion among other consumers.

Originality/value

This research innovates by presenting, for the first time, a conceptual model of brand credibility specific to the non-prescription medicines market, thus contributing to a better understanding of this issue by companies and brand managers of the pharmaceutical industry.

Abstract

Purpose

The purpose of this paper is to empirically investigate the following relationships in the Asian sports sponsorship context: first, the influence of self-congruity and perceived congruence on sponsor brand identification and sponsor credibility, respectively; second, the influence of sponsor brand identification and sponsor credibility on sponsor brand equity; and third, the mediating effect of sponsor brand identification and sponsor credibility on the relationship that self-congruity and perceived congruence each have with sponsor brand equity.

Design/methodology/approach

A field study was conducted in Taiwan, where 410 questionnaires were collected from baseball fans of the Chinese Professional Baseball League (the local professional baseball league).

Findings

The findings support all of the hypotheses and reveal that self-congruity and perceived congruence leverage sponsor brand equity through sponsor brand identification and sponsor credibility, respectively. Both sponsor brand identification and sponsor credibility partially mediate the relationship that self-congruity and perceived congruence each have with sponsor brand equity.

Practical implications

The findings of this study can assist sponsorship managers in realising how to leverage a sponsor brand equity.

Originality/value

The conceptual model investigated both direct and indirect (i.e. mediated) effects by providing different theoretical explanations to explore how self-congruity and perceived congruence leverage sponsor brand equity in the Asian sports sponsorship context.

Abstract

Purpose

The purpose of this paper is to learn how strategic hybrid orientation – constructed from brand and market orientations – is related to the brand awareness, brand credibility, and financial performance of business-to-business (B2B) small- and medium-sized enterprises (SMEs).

Design/methodology/approach

The questionnaire was used in a survey to collect data from 250 Finnish B2B SMEs. The sampled firms were categorized into four clusters according to a two-by-two matrix, and their relationships with the brand performance outcomes were examined using one-way ANOVA and multiple regression.

Findings

The results indicate that strategic hybrid orientation is positively related to all three dimensions of brand performance, showing that two dissimilar orientations can complement each other in improving brand performance outcomes. However, the strength of complementary interaction seems to vary depending on the degree to which brand- and market-oriented attributes dominate in a firm’s strategy.

Originality/value

This is one of the first studies to provide empirical evidence to support the concept of strategic hybrid orientation for branding in B2B SMEs. This study aims to contribute to existing research on SME branding by capitalizing on B2B branding and strategic management literatures.

Abstract

Purpose

This study aims to examine the influence of five sports celebrity personality (SCP) attributes – attractiveness, expertise level, credibility, trustworthiness and character – on consumers' purchase intentions (CPI). It identifies celebrity brand congruence (CBC), endorsed brand celebrity (EBC) and transfer of brand image (TBI) as antecedents of CPI.

Design/methodology/approach

The purposive sampling technique was used to collect the data from 838 respondents. This study developed a multidimensional construct for SCP. The covariance-based structural equation modeling (SEM) technique was used to examine the relationship between SCP and the endorsed brand. The study used CBC as a mediator and EBC and TBI as partial mediators. The direct and indirect effect of SCP on CPI was investigated using CBC, EBC and TBI as mediators.

Findings

This study supports the importance of three antecedents (i.e. CBC, EBC and TBI) on CPI. It finds congruence across SCP and CBC variables, and a positive impact of SCP on EBC and TBI variables. Also, it exhibits a significant direct effect of CBC on EBC and TBI, whereas the direct effect of CBC on CPI is not substantial. The indirect effect of CBC through mediating variables EBC and TBI found to be significant.

Research limitations/implications

This study concludes that sports celebrity endorsement is essential to transfer the positive celebrity image to the endorsed brand image. However, it is not merely sufficient to influence the buyers' purchase conduct; the brand credibility additionally assumes to take a role in changing their behavioral intentions.

Originality/value

This study contributes to the sports marketing literature by its novelty in analyzing the sports celebrity personality at a multidimensional level. It uses SCP's different attributes as one construct and studies its impact on CPI by taking CBC, EBC and TBI as mediators. The results of this study equip sports management professionals with the knowledge to build better long-term relationships with consumers.

Abstract

Examines the fourteenth published year of the ITCRR. Runs the whole gamut of textile innovation, research and testing, some of which investigates hitherto untouched aspects. Subjects discussed include cotton fabric processing, asbestos substitutes, textile adjuncts to cardiovascular surgery, wet textile processes, hand evaluation, nanotechnology, thermoplastic composites, robotic ironing, protective clothing (agricultural and industrial), ecological aspects of fibre properties – to name but a few! There would appear to be no limit to the future potential for textile applications.

Abstract

Purpose

Recently, the usage of melt blown products in many areas has increased. In melt blown process, generally polymers have been used. There are a variety of polymers. Characteristics of melt blown nonwovens have changed significantly depending on the polymer type. Also, there are several parameters such as die temperature, die-to-collector distance (DCD), air pressure, etc. that modify the nonwovens in melt blown process. The purpose of this paper is to investigate the effect of these parameters on the characteristics of nonwovens made up of polyethylene (PE).

Design/methodology/approach

In the melt blown process, two die temperatures, three different die air pressures and three different DCDs were used. In total, 18 samples were produced. On produced samples, thickness, tear and tensile strengths, fiber diameter, basis weight tests were done. Also SEM observations were obtained.

Findings

It was observed that parameters studied have a significant effect on characteristics of the produced nonwoven. Fiber diameter, basis weight and strength decrease by depending on factors. Also, it was observed that temperature has an effect, but slight. This work shows that higher temperatures should be studied. Finer and uniform fiber diameter is obtained with an increase in air pressure.

Research limitations/implications

PE is becoming increasingly important in nonwovens due to its lower melting point for processing and softer feel in nonwoven products.

Practical implications

Although the use of PE in polymer-laid nonwovens, especially as bicomponent fibers, has been growing in recent years, there are limited data on their processability and performance. In this context, with the availability of relatively higher melt flow rate PE, understanding the processability and structure and properties of the melt blown PE is very helpful in designing and developing the right products. This research was conducted to evaluate the processability of the PE resin using a typical PP melt blowing pilot line and to determine the structure and properties of the formed webs.

Originality/value

PE has superior properties such as excellent chemical resistance, good fatigue, wear resistance and higher impact strength. Also, PE provides good resistance to organic solvents, degreasing agents and electrolytic attack. PE has lower working temperatures than polypropylene, is light in weight, resistant to staining and has low moisture absorption rates. Thus, this study provides important contributions to the area since there are no data reported about the effect of various processing parameters on the structure and properties of PE melt blown nonwovens.

Abstract

Purpose

Brand authenticity has emerged as a strategic imperative for many firms. The purpose of this paper is to empirically examine the effect of consumer perceptions of brand marketing communications on brand authenticity of fast-moving consumer goods.

Design/methodology/approach

Direct and indirect pathways from brand marketing communications to brand authenticity were conceptualized. Data were collected from US energy drink consumers and analysed using structural equation modelling. Multiple marketing mix variables and context-relevant covariates have been controlled for.

Findings

Direct and indirect pathways to building brand authenticity have been observed. The total effect of brand marketing communications on brand authenticity is strong, thereby highlighting the predictor’s overall effectiveness in shaping the ultimate outcome.

Research limitations/implications

The focus on consumer-perceived authenticity as opposed to objective authenticity complements the prior literature. An integrative perspective on brand marketing communications is offered, specifying it as an antecedent of perceived brand authenticity.

Practical implications

An important implication is that investments into brand marketing communications will likely influence perceived brand authenticity. Such investments may also have favourable implications for the clarity of brand positioning. Overall, brand marketing communications are effective tools for building consumer-perceived brand authenticity.

Originality/value

A need to outline managerially controllable drivers of authenticity was addressed. How consumer perceptions of brand marketing communications influence brand authenticity via direct and indirect mechanisms was demonstrated. The existence of authenticity in fast-moving consumer goods was also demonstrated.

Abstract

Purpose

The term smartness has been discussed in the academia for many years; prior research has listed numerous advantages and encouraged business entities to implement smart technologies. However, stakeholders’ knowledge level, support intention and barriers to smart technology have been under investigated. Without the support of stakeholders, smart projects can hardly be implemented. This paper aims to explore the above-mentioned under investigated area and identify the gaps between academia and the hotel industry in Taiwan.

Design/methodology/approach

In-depth interviews were conducted with nine hotel stakeholders in Taiwan with investors, owners, managers, technology suppliers and information technology consultants. Three key areas were focused on: smart hotel definition, expectations from smart hotel and known barriers for implementing smart technologies.

Findings

The definition of smart hotel among all stakeholders was inconsistent. Stakeholders defined a smart hotel according to their role in the organization: revenue boost, service customization, operations effectiveness and in-room automation. However, the key functions of smart technologies, such as interconnectivity and interoperability with business partners’ application (e.g. online travel agencies) and linkage to external Big data for accurate revenue forecast, were not mentioned by the interviewees. In addition, social media monitoring, robots and artificial intelligence were not mentioned during the interview.

Originality/value

This study attempted to identify Taiwanese hotel stakeholders’ perspective on smart hotel and to compare the outcome with academic research. The result indicated that there is a big gap in the definition of “smart hotel” among stakeholders and academia and reflected several barriers that prohibit hotel owners and investors in implementing smart systems.

Abstract

Purpose

Commercial healthcare and hospital‐based web sites appear to exhibit distinctive formats. This paper aims to compare two award winning medical web sites with two top commercial healthcare web sites in an effort to determine significant predictors of positive attitudes toward the web sites when actively searching for healthcare information.

Design/methodology/approach

Three linear regressions were utilized to test the paper's hypotheses. Subjects entered a computer laboratory and were given search tasks for health information to complete within four web sites (two commercial and two hospital‐based web sites – order randomized).

Findings

The study shows how user perception, attitude and gratification are revealing of the strengths and weaknesses of hospital‐based vs commercial healthcare web sites as a means of providing users with healthcare information. Commercial healthcare web sites are viewed significantly more positively than hospital‐based web sites, revealing that overall web site quality and ease of use to be the dominant predictors of positive attitudes toward the web sites.

Research limitations/implications

The ecological validity of using real web sites presents challenges in terms of controlling for alternative explanations stemming from within web site type. Future research could explore different tasks that can be facilitated by medical web sites and assess the attributes of the web sites accordingly.

Practical implications

The paper can help design and develop better hospital‐based and commercial healthcare web sites.

Originality/value

This research explored actual information search behavior and the resulting web site user perceptions in an effort to bring academic inquiry into practice. Nothing similar to the hypotheses or this methodology has been found within the web site effectiveness literature, neither generally nor specifically within the healthcare industry.
