This paper was written in response to an increasing number of requests by marketing people to provide an answer to the question “What is the essence of my brand?” Many of these queries come from companies who already have vast amounts of qualitative research, tracking information on advertising awareness and brand imagery, in addition to continuous data of various types. None of these seem to be able to provide a measurable understanding of the emotional values which shape the consumer‐brand relationship.

This chapter asks: How do Internet users react to COVID-19 conspiracy theories spread on social media? It presents the findings of a content analysis and critical discourse analysis of user comments collected from social media postings that advance COVID-19 conspiracy theories. A total of 2,847 comments made to seven social media postings whose authors support COVID-19 conspiracy theories were collected, coded and analysed.

The analysis shows the contested character of the communication of COVID-19 conspiracy theories and the role of the friend/enemy scheme, verbal attacks, violent threats, satire and humour in such communication processes.

Entrepreneurship-related research in management and organizational journals has experienced rapid growth, particularly in the last several years. The purpose of this study is to identify the researchers and universities that have had the greatest influence on entrepreneurship research since the turn of the century. Using a systematic and comprehensive study identification protocol, the authors delve into the individual and institutional actors contributing to scholarship in entrepreneurial studies for the period from 2000 to 2015. Examination of top-tier management and organizational journals revealed that a total of 371 entrepreneurship-related articles were published during this period by 618 authors from 303 different institutions. Rankings for the most prolific individuals as well as institutions, adjusted and unadjusted for journal quality, are presented. The article concludes with a discussion of the limitations and implications of the research undertaken here.

This chapter examines the increased levels of cross-asset price comovement and its relationship with the recent rounds of “extraordinary intervention” from the US Federal Reserve. The results show that, even after controlling for the preceding financial crisis, asset return volatility, investor risk perceptions, and channels of monetary stimulus, historically unrelated financial asset returns experienced abnormal changes in their conditional correlations. The strength of these cross-asset correlations is directly linked to periods of Federal Reserve interventions yet disappear when the interventions were (in fact or were perceived to be) withdrawn. Despite being studied extensively in the academic literature, no traditional intervention channels can explain the changes in cross-comovement. It is proposed that the Fed’s extraordinary stimulus caused investors to use Fed announcements as a common, low-cost information source on which they used to make common portfolio-allocation decisions. The changes in comovement during the intervention period may have reduced investor welfare for those with longer-horizon allocation strategies, those not prepared for the eventual ending of the stimulus, and for underfunded liability-optimizing portfolio managers (e.g., state pension funds).

In spite of the high interest in thermally sprayed aluminium (TSA) to protect offshore structures, pipelines, risers, etc., data correlating the exposure of TSA-coated steel in hot seawater to its performance are lacking. No information is available on the performance of TSA in hot seawater, especially when damaged. This paper aims to address this knowledge gap and report the corrosion performance of damaged TSA on carbon steel exposed to boiling synthetic seawater for different periods (up to 5,000 h). It also attempts to understand the mechanism of formation of calcareous deposits in boiling synthetic seawater by using various characterisation tools.

Twin wire arc spray was used to coat carbon steel specimens with commercially pure aluminium. Holiday was drilled on the coated surface to expose the underlying steel, amounting to 4 per cent of the specimen surface area. These specimens were then exposed to boiling synthetic seawater for different periods: 2, 68, 188, 335 and 5,000 h. During exposure, the potential was monitored (vs standard calomel electrode [SCE]) and linear polarisation resistance (LPR) method was used to calculate the corrosion rate (CR). After exposure, these specimens were analysed by using characterisation tools such as X-ray diffraction (XRD) and scanning electron microscope (SEM)/energy-dispersive X-ray spectroscopy (EDX).

The TSA-coated steel samples with 4 per cent holiday showed a CR of approximately 0.008-0.015 mm y⁻¹ and a stable potential (E_corr) around −800 mV (SCE), when exposed to boiling synthetic seawater for approximately 5,000 h. Microstructural characterisation established that the deposits comprised brucite [Mg(OH)₂] only (this is very different to what has been reported at ambient temperatures). The stable potentials obtained after 5,000 h suggest that the brucite layers provided effective corrosion mitigation. Thus, TSA seems to show the potential to protection hot carbon steel risers, even when damage exposing the external steel surface to the seawater is present.

The mechanism of calcareous deposit formation has been studied for many years, but most of the previously reported studies concentrate on low or ambient temperature behaviour. The reported studies mainly concentrate on the application of cathodic protection, rather than the effect of TSA. This is the first journal paper where the behaviour of damaged TSA in boiling synthetic seawater has been reported. The formation of brucite-only layer in the damaged area adjacent to the steel surface in boiling synthetic seawater is novel. And the mechanism of formation of this layer has been explained in the paper.

This study aims to reveal the differential concentration corrosion (DCC) mechanism, which has been ignored by researchers for a long time.

The ionic conductive layer near the pipe wall was extracted and discretized. In the case of DCC, the equations of corrosion potential after polarization in units are derived according to Kirchhoff’s Law. By solving these equations, the corrosion potential and current on situation of DCC are calculated.

DCC can change origin distribution of (nature) potential and current greatly; it will cause polarization. The positions with original lower corrosion potential will produce anodic polarization; meanwhile, the speed of corrosion also increases; the position with original higher corrosion potential will produce cathodic polarization, and the corrosion current is also decreased. Generally speaking, the potential will be homogenized by DCC mechanism.

This model makes an in-depth analysis of the traditional FAC theory, greatly supplements it and enriches the theory.

In line with current research efforts to develop eco-friendly strategies for corrosion mitigation, the purpose of this study is to appraise the anti-corrosion potential of selected amino acids on magnesium corrosion in sodium chloride solutions.

The corrosion inhibition of magnesium in aqueous solutions in the presence of benign, eco-friendly and readily available amino acids (alanine, arginine, histidine, lysine, proline) were evaluated using electrochemical methods.

Amino acids suppressed magnesium corrosion rate in aqueous sodium chloride solutions. The order of inhibition efficiency (%IE) was as follows: alanine < arginine < histidine < lysine < proline. The open circuit potential shift with respect to the blank was less than 0.085 V_SCE, indicating that the amino acids are mixed-type corrosion inhibitors. In addition, the %IE of the amino acids was inversely proportional to the molecular weight. The results obtained indicate that the amino acids can serve as sustainable eco-friendly corrosion inhibitors for magnesium with the best inhibition efficiency attributed to proline with an efficiency of 85.1%.

New information on the application of amino acids as green sustainable corrosion inhibitors is provided herein.

Service quality and relative performance of public universities in East Africa.

Exploratory survey of three public universities in East African countries namely Moi, Makerere and Dar es salaam universities from three East African countries of Kenya, Uganda and Tanzania, respectively. Student perceptions are elicited on service quality and relative performance. Comparative analysis is done. A sample size of 450 respondents from a target population of > 50,000 is derived using a multistage sampling technique. Structured questionnaire is used to extract both nominal and ordinal data, the latter utilizing items anchored on a five-point Likert scale. Modified SERVQUAL and performance were standardized. Descriptive, one-way ANOVA, factor analysis, Pearson product moment correlation and multiple regression was used to analyze the data.

Modified SERVQUAL dimensions were confirmed, centrality of tangibility and reliability established, while importance of responsiveness was disapproved. Relative variation in service quality and relative performance across three countries universities was found to be significant. Finally significant effect of service quality on performance of universities was also established.

Service quality and relative performance in higher education could be subjected to international verification and evaluation at the risk of cultural and contextual bias.

The paper provides insights on the relative importance of service quality dimensions and their effects on relative performance. This guides practitioners on prioritization of the service quality dimension that are central to relative performance.

Knowledge of the key dimensions of service quality that are central to relative performance and their variation across institutional contexts guides institutions of higher education in fulfilling their social responsibility to customers by meeting their expectations in service quality.

The value of this paper lies in the application of SERVQUAL model to higher education in an international context. Evaluation of link between service quality and relative performance, and also examining variation across universities under unique cultural and contextual situations.

To cope successfully with the pressures imposed by a devastating pandemic and other challenges, companies and policymakers need to look at how they conceptualize, define, measure and operationalize “value”. This paper aims to support this conversation.

This study presents a historical review of how the value construct has been conceptualized over time, demonstrating that its history is one of tension and debate with conceptualizations swinging between objective (i.e. the value of something exists independent of the observers) and subjective (i.e. the value of something depends on the personal response of the observer to what is being considered) views over time.

This paper outlines the implications to researchers of value’s low construct clarity, offering suggestions designed to exploit rather than ignore the duality of the value construct. Instead of thinking of the value construct as being subjective or objective, this study recommends that scholars consider value’s objectivity and subjectivity as being interrelated and complementary. The paper recommends that researchers use both quantitative and qualitative methodologies in studying this construct.

A major limitation of this paper is the word count limitation restricting the extent to which this paper could explore a more comprehensive list of the conceptualizations of value throughout history.

This paper presents practitioners with a nuanced understanding of value that should assist those interested in examining the worth of investments with observable expenses but less quantifiable outputs.

The authors have not found a similar analysis of the various conceptualizations of value.

This research paper explores the type and amount of business communication education given to students in Master of Business Administration (MBA) programmes, and offers insight into the thinking of those who supervise and teach business communication within those programmes. While this particular research study focuses on US MBA schools, it is advocated that this subject and research findings have global relevance. Communication and public relations skills have been recognised as being critical to the success of aspiring managers and business leaders. Prospective managers need to possess not only the skills of communication, but also an appreciation of strategic business communication factors. However, most MBA curricula do not require or recommend communication education for students. This paper compares the findings of two studies: research conducted in 1995–96 (n = 215, 31.5 per cent response rate) replicated a 1991 study (n = 51, 26 per cent response rate). In addition, the paper discusses prior research on the subject and the role and quality of business communication currently found in MBA curricula. It also includes a model communication curriculum for MBA programmes and proposes suggestions for additional research.
