Although endorsers are thought to be highly effective when they match-up with a product, the current understanding of endorser match-up offers little insight for distinctions between equally attractive and trustworthy endorsers who have equivalent expertise in the product category, yet still diverge in their performance. Therefore, the main purpose of this research is to understand how a match between social judgments (i.e. warmth vs competence) of a celebrity endorser and specific advertising appeals (i.e. symbolic vs utilitarian) can improve consumer responses to an endorsement.

A preliminary study empirically distinguishes perceptions of warmth and competence from prevailing celebrity endorser evaluative criteria. Then, the authors conduct multiple 2 (warmth vs competence) × 2 (symbolic vs utilitarian) between-subjects experiments to demonstrate the effect of matching social judgments and advertising messaging, across celebrity genders (i.e. male and female), forms of marketing communications (i.e. print ads and interactive online ads) and types of brands (i.e. well-established and new/unknown).

The findings demonstrate that matching celebrity endorser social judgments with the appropriate type of advertising messaging positively influences consumer response to the brand for both male and female endorsers. Additionally, despite a commonly held belief that celebrity endorsements are more effective at changing attitudes than actual behaviors, for interactive online ads, the authors find that the match strategy can motivate consumer response through two different pathways. For well-established brands, the match improves overall brand response predominately through cognitive and behavioral mechanisms. Alternatively, for new or unknown brands, the match initially impacts affective responses, which are subsequently related to consumers shopping a brand’s product category, rating a brand higher in customer recommendations, choosing a brand’s products over top competitors and paying more for the brand’s offerings.

The main contribution of this research is the demonstrated support for an alternative and effective application of the match-up hypothesis, based on a fit between the endorser and the advertising messaging itself.

This paper aims to present an efficient and simplified proportional-integral/proportional-integral and derivative controller design method for the higher-order stable and integrating processes with time delay in the cascade control structure (CCS).

Two approaches based on model matching in the frequency domain have been proposed for tuning the controllers of the CCS. The first approach is based on achieving the desired load disturbance rejection performance, whereas the second approach is proposed to achieve the desired setpoint performance. In both the approaches, matching between the desired model and the closed-loop system with the controller is done at a low-frequency point. Model matching at low-frequency points yields a linear algebraic equation and the solution to these equations yields the controller parameters.

Simulations have been conducted on several examples covering high order stable, integrating, double integrating processes with time delay and nonlinear continuous stirred tank reactor. The performance of the proposed scheme has been compared with recently reported work having modified cascade control configurations, sliding mode control, model predictive control and fractional order control. The performance of both the proposed schemes is either better or comparable with the recently reported methods. However, the proposed method based on desired load disturbance rejection performance outperforms among all these schemes.

The main advantages of the proposed approaches are that they are directly applicable to any order processes, as they are free from time delay approximation and plant order reduction. In addition to this, the proposed schemes are capable of handling a wide range of different dynamical processes in a unified way.

The aim of the study was to show that a new method, using a look-up table technique, can be used to detect the presence and position of an inclusion embedded in a tissue-like material. Due to the time-consuming nature of the finite element (FE) method or FEM, real-time applications involving FEM as part of a control loop, are traditionally limited to slowly varying systems. By using a simplified two-dimensional FE model and a look-up table, we show by simulations and experiments that it is possible to achieve reasonable computational times in a tactile resonance sensor application.

A piezoelectric disk was placed in the center of a silicone rubber disk (SRD) with viscoelastic properties, where it acted as both sensor and actuator and dissipated radial acoustic waves into the silicone. The look-up table was constructed by calculating the radial Lamb wave transition frequencies in the impedance frequency response of the sensor while varying the position of an inclusion. A position-matching algorithm was developed that matched measured and calculated Lamb wave transitions and thereby identified the presence and position of an inclusion.

In an experiment, the position of a hard inclusion was determined by measuring the Lamb transition frequencies of the first radial resonance in two SRDs. The result of the matching algorithm for Disk 1 was that the matched position was less than 3% from the expected value. For Disk 2, the matching algorithm erroneously reported two false positions before reporting a position that was less than 5% from the expected value. An explanation for this discrepancy is presented. In a verifying experiment, the algorithm identified the condition with no inclusion present.

The approach outlined in this work, adds to the prospect of developing time-sensitive diagnostic instruments. This approach has the potential to provide a powerful technique to quickly present spatial information on detected tumors.

This study aims to explore how source type can influence organizational assets proposed by source credibility theory (SCT) when paired with matched situational crisis communication theory (SCCT) strategies for accidental, preventable, and victim crises. Crisis communication delivered online provides an invaluable outlet for organizations to disperse information to stakeholders quickly. It has been shown that receivers of this information have motivational assumptions about sources having their own agenda for producing content. Thus, it is important to explore how sources tasked with delivering crisis responses can influence perceptions of the sincerity and credibility of the message.

The researchers conducted a 3 (crisis response: matched accidental, matched preventable, matched victim) × 3 (source type: organization, CEO, The New York Times) online between-subjects experimental design (N = 623).

By identifying how the source disseminating crisis responses influences message perceptions, findings from this study recognize how the crisis response is situated in a greater context. Since perceived sincerity and credibility were found to influence message acceptance and reputation, making intentional decisions that acknowledge both within a crisis communication strategy may benefit both future practice and research applications.

The current study advances understandings afforded by SCCT, along with SCT, by experimentally testing the influence of these variables within crisis responses on outcomes such as account acceptance and organizational reputation.

This study situates in the context of Chipotle's food safety issue and seeks to understand how their primary customers perceive their crisis response messages after learning of the outbreaks. The current study incorporates the framework of situational crisis communication theory (SCCT; Coombs, 2007) and public segmentation model (Rawlins, 2006) to understand the effectiveness of crisis response messages. It aims to examine the role of public segmentation in situational crisis communication and investigate the effects of three crisis response strategies according to SCCT on different public segments.

The SCCT provides guidelines for understanding the effectiveness of different crisis response strategies. The current study showcases the importance of public segmentation in the SCCT model through the lens of stakeholder theory. A 3 (crisis response strategy: deny, diminish, rebuild) × 4 (public segment: advocate, dormant, adversarial, apathetic) factorial experiment was conducted.

The findings suggest that advocate public expressed more positive evaluation about the company when exposed to rebuild and deny strategies. Both dormant and adversarial stakeholders reported positive responses on rebuild and diminish strategies. However, no difference was found among apathetic public.

The researchers attempt to make a modest contribution in this direction by reporting results from an empirical experiment that examined the effects of crisis response strategies on different public segments. The findings suggest an effective message tailoring approach to target different public segments. Thus, the results of this study are expected to benefit relevant corporations and public relations practitioners.

This paper aims to examine the consistency between firms’ stakeholder-friendly responses to the COVID-19 pandemic and their environmental, social and governance (ESG) ratings. Consistent firms are those with high prior ESG ratings that actively support stakeholders during the COVID-19 crisis.

The authors use data from JUST Capital, which tracks Russell 1000 firms’ actions in response to the pandemic, to examine the relationship between pre-pandemic ESG ratings and their COVID responses towards employees, customers and communities. The authors also analyse the impact of firms’ consistency between pre-pandemic ESG ratings and stakeholder-friendly COVID responses on ESG ratings and stock returns.

This study finds that firms with higher pre-pandemic ESG ratings are more likely to support their stakeholders during the pandemic. The authors also find that firms with high ESG ratings before the pandemic experience a decline in their ESG ratings if they do not actively support their communities during the COVID-19 crisis, although insufficient employee/customer support does not impact their ESG ratings. Finally, the authors find that firms with higher pre-pandemic ESG ratings that continue to uphold their ESG commitments through community assistance during the pandemic achieve higher stock returns compared to inconsistent firms.

The results reveal gaps in how comprehensively ESG agencies assess firms’ crisis responses, highlighting areas for rating improvements. The findings contribute to sustainable development by revealing the importance of firms upholding their ESG commitments during crises to maintain stakeholder trust and drive long-term value creation.

The findings underscore the need for responsive, transparent ESG rating processes to support the integration of sustainability considerations into corporate practices and investment decisions, particularly during evolving societal expectations during crises.

To the best of the authors’ knowledge, this study is the first to investigate how pre-pandemic ESG ratings explain firms’ stakeholder-friendly responses during the COVID-19 pandemic and analyse the integration of these responses and pandemic risks into ESG ratings during the crisis.

The lack of user response in written submissions on accounting standards has been noted in previous research. That lack of user response has limited empirical investigations with the result that lobbying by users has to be understood largely from theoretical literature in the political and social arena. Aims to add empirical data to the understanding of the user perspective, taking as a focus for the investigation the lobbying of the UK Accounting Standards Board in respect of the Operating and Financial Review. Four issues are chosen for analysis: usefulness to users, effectiveness of voluntary compliance, confidentiality and provision of forward‐looking information. Shows that the ASB’s responses on these four major issues are rational in terms of the relative intensity of lobbying. Using interview methods to obtain user responses shows that a different perception of lobbying intensity may be derived from a comparison of preparer and user responses, such that preparers’ views may have given too negative an impression to the ASB. The relative persuasive power of different arguments is shown to depend on how the comparison is undertaken. Uses the quantitative analysis of responses as a base from which to explore the potential for strategic lobbying to disguise self‐interested motivation and provides some insight on the lack of user response.

Displaying a sense of humour provides various interpersonal benefits including reducing tension and promoting conflict resolution, but should a firm use humour in response to publicly viewable online customer complaints after a service failure? The purpose of this study is to demonstrate that a firm’s use of humour in response to negative online consumer reviews has both positive and negative effects on perceptions of corporate image from a customer-as-onlooker perspective.

Three experimental studies are conducted and analysis of variance is used to empirically test the hypotheses.

Although humorous responses have an unfavourable influence on perceived trustworthiness of the firm, they have a favourable influence on perceived excitingness of the firm. The former influence is tied to lower perceived firm sincerity, whereas the latter is tied to higher perceived firm innovativeness and coolness. Furthermore, humour within the customer complaint itself is shown to moderate the influence of humorous responses on perceptions of the firm. Finally, regardless of the type of humour used (i.e. affiliative or aggressive humour) in the humorous response, the positive effect of humorous response remains strong, although aggressive humour further aggravates the negative impact of humorous response on trustworthiness.

The experimental set-up may limit external validity of the study, and the research is limited to the variables examined.

Humorous response is identified as a non-traditional approach to online customer complaints that poses a double-edged sword for managers of service organizations. Firms should avoid using humour in online service recovery if perceptions of trustworthiness are critical or if complaints are written in a neutral tone. However, such responses may be successfully used when a firm wants to position itself as exciting and if complaints are also humorous. Finally, firms are advised to avoid aggressive humour.

The present research represents one of the few studies in marketing to examine the potential of injecting humour into complaint management and service recovery. In addition, this study considers the consumer-as-onlooker perspective inherent in social media.

The purpose of this paper is to illustrate inconsistent findings regarding motivations for the implementation of information technology (IT) in the supply chain. Two main theoretical perspectives emerge from the literature. The first predicts a logical progressive implementation of technology over time. The second views situational factors as moderating progressive implementation over time. The authors propose a third, calculative IT implementation model and empirically assess the validity of these diverging models.

The authors took a qualitative, theory-testing approach. Cross-sectional surveys conducted in 2001 and 2011 – yielding responses from 62 matching firms – showed dynamic IT implementation patterns over time and allowed the selection of nine case studies for comparison.

Results provide substantial support for a calculative model alongside the situational and progressive perspectives. This model addresses three problematic assumptions that underpin the progressive and situational perspectives: that IT implementation will follow logical stages; that implementation of these technologies represents a rational choice; and that managers implement these technologies to improve the performance of entire supply chains.

The empirical investigations were limited to Australian manufacturers. Further studies should extend the generalisability of the findings and study the phenomenon in different contexts.

The study enhances practitioners’ understanding of the difficulties and complexities of IT implementation decisions among supply chain partners. Such an understanding may motivate managers to pursue IT adoption that goes beyond addressing locally focused performance metrics.

The findings make a significant theoretical and practical contribution and provide the basis for isolating and operationalising the calculative model for further empirical testing.

If individuals exhibit less ethical behavior in the workplace than in their personal decisions, this may constitute evidence of role morality behavior. Role morality can be defined as “claim(ing) a moral permission to harm others in ways that, if not for the role, would be wrong” (Applbaum, 1999. Ethics for adversaries: The morality of roles in public and professional life (p. 3). Princeton, NJ: Princeton University Press.) To investigate this issue, 55 practicing accountants completed and returned the experimental survey. Results show that in many situations, business decisions were less ethical than personal decisions, consistent with the theory of role morality. The implications and limitations of this study as they relate to practicing accountants are discussed.
