Abstract

Purpose

Stiffened plates have been widely used in civil, marine, aerospace engineering. As a kind of thin-walled structure operating in complex environment, stiffened plates mostly undergo a variety of dynamic loads, which may sometimes result in large-amplitude vibration. Additionally, initial stresses and geometric imperfections are widespread in this type of structure. Furthermore, it is universally known that initial stresses and geometric imperfections may affect mechanical behavior of structures severely, particularly in dynamic analysis. Thus, the purpose of this paper is to study the stress variation rule of a stiffened plate during large-amplitude vibration considering initial stresses and geometric imperfections.

Design/methodology/approach

The initial stresses are represented in the form of initial bending moments applying to the stiffened plate, while the initial geometric imperfections are considered by means of trigonometric series, and they are assumed existing in the plate along the z-direction exclusively. Then, the dynamic equilibrium equations of the stiffened plate are established using Lagrange’s equation as well as aforementioned conditions. The nonlinear differential equations of motion are simplified as a two-degree-of-freedom system by considering 1:2 and 1:3 internal resonances, respectively, and the multiscale method is applied to solve the equations.

Findings

The influence of initial stresses on the plate, stresses during internal resonance is remarkable, while that is moderate for initial geometric imperfections. (Upon considering the existence of initial stresses or geometric imperfections, the stresses of motivated modes are less than the primary mode for both and internal resonances). The influence of bidirectional initial stresses on the plate’s stresses during internal resonance is more remarkable than that of unidirectional initial stresses. The coupled vibration in 1%3A2 internal resonance is fiercer than that in internal resonance.

Originality/value

Stiffened plates are widely used in engineering structures. However, as a type of thin-walled structure, stiffened plates vibrate with large amplitude in most cases owning to their complicated operation circumstance. In addition, stiffened plates usually contain initial stresses and geometric imperfections, which may result in the variation of their mechanical behavior, especially dynamical behavior. Based on the above consideration, this paper studies the nonlinear dynamical behavior of stiffened plates with initial stresses and geometrical imperfections under different internal resonances, which is the originality of this work. Furthermore, the research findings can provide references for engineering design and application.

Abstract

Purpose

The purpose of this paper is to study the resonance failure sensitivity analysis of straight-tapered assembled pipe conveying nonuniform axial fluid by an active learning Kriging (ALK) method.

Design/methodology/approach

In this study, first, the motion equation of straight-tapered assembled pipe conveying nonuniform fluid is built. Second, the Galerkin method is used for calculating the natural frequency of assembled pipe conveying nonuniform fluid. Third, the ALK method based on expected risk function (ERF) is used to calculate the resonance failure probability and moment independent global sensitivity analysis.

Findings

The findings of this paper highlight that the eigenfrequency and critical velocity of uniform fluid-conveying pipe are less than the reality and the error is biggest in first-order natural frequency. The importance ranking of input variables affecting the resonance failure can be obtained. The importance ranking is different for a different velocity and mode number. By reducing the uncertainty of variables with a high index, the resonance failure probability can be reduced maximally.

Research limitations/implications

There are no experiments on the eigenfrequency and critical velocity. There is no experiments about natural frequency and critical velocity of straight tapered assembled pipe to verify the theory in this paper.

Originality/value

The originality of this paper lies as follows: the motion equation of straight-tapered pipe conveying nonuniform fluid is first obtained. The eigenfrequency of nonuniform fluid and uniform fluid inside the assembled pipe are compared. The resonance reliability analysis of straight-tapered assembled pipe is first proposed. From the results, it is observed that the resonance failure probability can be reduced efficiently.

Abstract

Purpose

Oppositional organizational identities are fraught with conflict and often evoke powerful social and cultural identities. Such identities may be a divisive force among consumers. The purpose of this paper is to understand how consumers construct frames that facilitate identification with oppositional organizational identities.

Design/methodology/approach

The authors use online reviews from TripAdvisor.com and Yelp.com of the Creation Museum in Kentucky, USA. The Creation Museum is an ideal research context due to its location within American public discourse regarding religion and science. Through a grounded theory approach of the reviews, the authors propose three identity frames.

Findings

The data suggest that consumers primarily construct three frames to identify with the Creation Museum: transformational experiences, interpretive bricolage and oppositional scripts. Together, these frames engender resonance and facilitate consumer identification.

Originality/value

This paper is one of the first to examine how oppositional organizational identities garner consumer support. Given that consumers are increasingly attentive to organizational processes and the ubiquity of information technology, which reduces the costs of information and interaction, the study provides a much more holistic perspective on oppositional organizational identity and offers a multitude of future avenues for further research.

Abstract

Purpose

Live chat e-service provides a communication platform for online customers to make information inquiries and receive instantaneous assistance from a service representative. It is important for organizations to explore ways to improve their live chat e-service. The purpose of this paper is to propose a new organization–customer communication model (Schema Resonance Model), explicate how schema resonance can be achieved in live chat e-service, and investigate the impact of schema resonance on live chat e-service effectiveness, efficiency, customer satisfaction and intention of continued use.

Design/methodology/approach

A post-test only, between-subjects experiment was conducted. A total of 409 participants completed the experiment sessions, and 389 of these participants were used in the analysis.

Findings

Research results suggest schema resonance could improve the time efficiency of the live chat e-service while maintaining e-service effectiveness. Schema resonance could increase customer satisfaction with the overall e-service, the communication approach used by the representative and the information provided.

Research limitations/implications

Because a convenience sample was used in the experiment, results cannot be generalized to all live chat e-service users. Future research should include observation of real-world organization–customer live chat e-service sessions.

Practical implications

Organizations can consider applying the Schema Resonance Model in live chat e-service practices to enhance customer satisfaction and increase representatives’ service productivity.

Originality/value

This research proposes and tests a new organization–customer communication model to explore how organizations can improve live chat e-service in response to customers’ information inquiries.

Abstract

Purpose

The research analyzes the presence of two global brands – Fiat and International Federation of Association Football – in Brazilian demonstrations in conjunction with the 2014 World Cup. The purpose of this paper is to extend the brand cultural resonance construct and highlights its boundary-straddling nature. The analysis reveals the dynamics of brand meanings established including why some brands have their meanings enriched through collective appropriation, while others become vessels of negative content and targets of anti-consumption movements.

Design/methodology/approach

A multimethod approach, which included observation, analysis of cultural texts and in-depth interviews with 21 demonstrators, was adopted for the study.

Findings

The study extends the construct of brand cultural resonance proposing an additional facet, named Institutional Resonance. This dimension relates to the meanings that arise from a brand’s institutional role and interactions with other social institutions, like governments, the economy, religious, and educational systems. Institutional Resonance occurs when a certain brand becomes the archetypal representation of a social institution. This study also presents two forms of brand cultural resonance: arrows or targets. As arrows, brands lend their symbolic resources to the construction of protesters’ messages helping them to communicate their ideas. As targets, brands become social enemies and represent negative poles of social contradictions.

Originality/value

This study investigates consumer appropriation of marketers’ actions. The research depicts Institutional Resonance as an interactive and acute phenomenon which promotes a social negotiation on a playing field where different agents forge brand meanings and reputations.

Abstract

Purpose

This study aims to investigate whether engagement in philanthropic marketing after the 311 Japan earthquake crises had a positive effect on brand resonance and consumer satisfaction of CSR performance for Taiwanese companies. Additionally, the particular phenomenon of media self-regulation was integrated to explore the consolidated impact of philanthropic marketing, media self-regulation and brand resonance on consumer satisfaction of CSR performance.

Design/methodology/approach

The study used survey method to collect required data. The subjects of the study were 516 adults who were aware of the 311 Japan earthquake crises. Of the 476 survey questionnaires collected, 450 were identified as usable.

Findings

The results show that the constructs were highly positively correlated, meaning that post-disaster corporate philanthropic marketing can enhance brand resonance and consumer satisfaction of CSR performance. Media self-regulation was found to have a significant influence on philanthropic marketing and brand resonance. However, it did not exert any significant effect on consumer satisfaction of CSR performance.

Research limitations/implications

Because of the chosen research method and surveyed subjects, the research results may lack generalizability. Therefore, researchers are encouraged to test the proposed research model further with additional subjects and variables.

Practical implications

A good impression of the brand usually makes consumers generate brand resonance. This study reveals that a higher level of brand resonance may lead to higher consumer satisfaction of CSR performance. This implies that local and international companies should engage in philanthropic marketing programs, as it will not only support charitable organizations but also enhance the firm’s corporate image.

Social implications

This study points out that the positive coverage of the disaster could give the audience a positive impression, rather than showing provocative, violent or sexual content to push viewership. At the time when disasters become increasingly common, people’s expectations of the media will also elevate. Dramatization, exaggeration and information overload make the audience distrust the media and constantly seek the truth behind the story. Content generated by online bloggers and citizen reporters (ordinary people) is an alternative source for true, fast and in-depth reports.

Originality/value

This study differs from earlier studies researching disastrous events in that they were taking the perspective of natural sciences, while we adopted the management viewpoint to evaluate the 311 crises and took media self-regulation into account. It is the first to reveal that media’s self-regulated coverage of the disaster seems to have a positive effect on corporate philanthropic marketing and brand resonance.

Abstract

THOUGH resonance tests are now becoming familiar to most aeronautical engineers, it is perhaps desirable at the outset to indicate their general nature. They are vibration tests carried out on an aeroplane with the immediate object of determining the natural frequencies and modes of its parts, and in particular, of its wings. The ultimate aim of resonance tests on a given aeroplane is to provide data to assist in the estimation of its critical flutter speeds, so that its liability to flutter troubles may be assessed.

Abstract

Purpose

To predict the occurrence of the combination resonances in parametrically excited, simply supported laminated composite plates in contrast to the simple resonances by using first‐order shear deformation lamination theory considering the effects of shear deformation and rotary inertia.

Design/methodology/approach

Finite element technique is applied to obtain the equilibrium equation of a plate. Modal transformation is applied to transform the equilibrium equation into a suitable form for the application of the method of multiple scales (MMS). The MMS is applied to obtain the boundaries of the simple and combination resonances.

Findings

The combination resonance zones contribute a considerable amount to the local instability region and the widths of combination resonance zones are comparable to those of the simple resonance zones for the loading of the small bandwidth at one end or for the concentrated edge loading.

Practical implications

Aircrafts, spacecrafts and many other structures such as ships, bridges, vehicles and offshore structures use the plate type elements, which are susceptible to dynamic instability.

Originality/value

It will assist the researchers of stability behavior of elastic systems.

Abstract

Purpose

Brand resonance will significantly improve the profits of the services industry in the twenty-first century. The purpose of this paper is to find the resonance score for modified customer-based brand equity (CBBE) model in mutual fund financial services and improve the conceptualization of customer-based mutual fund services’ brand equity through brand resonance.

Design/methodology/approach

The path values of SEM model was used to estimate the relative weights of criteria and sub-criteria in analytic hierarchy process (AHP) model and it was empirically tested with a sample of 240 mutual fund investors.

Findings

The brand resonance using AHP has been quantified. The resonance quantification of each brand has been demonstrated using two renowned Indian mutual fund services brands State Bank of India and Hong Kong and Shanghai Banking Corporation.

Research limitations/implications

The interdependency of the factors which influence the resonance score is not explored.

Practical implications

Research findings provide useful guidelines for fund managers/analysts of mutual fund services companies while improving the brand equity and strong brand’s resonance with investors.

Originality/value

The paper examines quantification of resonance for modified CBBE model in mutual fund services using data from a sample of investors in India with two mutual fund brands. The AHP structure model helps firms effectively quantify the resonance score.

Abstract

Developed in this chapter are the conceptual underpinnings and practices of an interdisciplinary “Indian Studies” course taught through a unique inquiry-based epistemological approach referred to as resonances. In providing a resource and model for others who teach sensitive and even controversial topics that include the study of other groups of people, this chapter progresses in four stages. Firstly, necessary insight is provided about the course’s unique context within state teacher certification requirements and standards documents. Secondly, the nascent theory of resonances is developed from and then as an alternative to dissonance theory and cultural matching. Thirdly, and continuing the development, practical, and pedagogical applications of resonance-as-inquiry are shared with indebtedness to autoethnography. And lastly, the relative successes and limitations of this particular epistemological approach are discussed phenomenologically.
