Abstract

The paper investigates the successful establishment of a strong corporate brand with a particular emphasis on analysing the corporate branding literature’s assumptions about coherency. Successful corporate branding is claimed to imply a shared set of coherent statements about the company’s values towards its external and internal stakeholders over time. An empirical test is applied to the coherency assumption. First, the coherency of a corporate brand over time is investigated as it develops in the media. Secondly, the coherency between two stakeholders’ perceptions of the corporate brand, organisational members and the media is investigated. This research suggests there are three distinct types of coherencies in corporate branding strategies over time: statement coherency, interpretation coherency and uniqueness coherency. On the one hand, a strong corporate brand is characterised by tight coherency, as top management’s statements about values remain the same over time and towards different stakeholders, ie statement coherency. On the other hand, a strong corporate brand is simultaneously characterised by a loose, or even absent, coherency between stakeholders’ interpretations of top management’s statements as well as a lack of coherency in stakeholders’ interpretations of the corporate brand over time, ie interpretation coherency. Finally, a third coherency phenomenon is observed, ie stakeholders’ emphasis on changing topics over time, which they relate to the corporate brand. Stakeholders agree that these themes are unique features and hence the company is considered unique, ie the uniqueness coherency. The implications of multiple interpretations are discussed as well as changing interpretations in corporate branding. It is argued that statement coherency is a necessary element in successful corporate branding, and the viability of the ambition to develop interpretation coherency over time and across stakeholders in corporate branding is discussed from the point of view of allowing room for interpretation incoherency. Finally, the question of maintaining uniqueness coherency is discussed: for how long can a company represent “newness” in the eyes of its stakeholders – including itself? Implications for management are discussed.

Abstract

Purpose

The study investigates the co-movements amongst real estate investments trust (REITs). This study examines the co-movements between the world and individual countries' REITs and the co-movements amongst country-pair REITs. This study explores the responsiveness of the REITs markets' co-movements to the 2008 global financial crisis (GFC), the coronavirus disease 2019 (COVID-19) pandemic and the Russian–Ukraine conflict.

Design/methodology/approach

The study employs a wavelet coherency technique and relies on data from six REITs markets over the 1995–2022 period.

Findings

The evidence shows a generally high level of coherency between the global and the country's REITs. The findings further indicate higher co-movements between some country pairs and a lower co-movement for others. The results suggest that the REITs markets increased in co-movements around the 2008 GFC, the COVID-19 pandemic and the Russian–Ukraine conflict. These increased co-movements mostly lasted for a short period suggesting REITs markets contagion around these global events. The results generally suggest interdependence between the global and the country's REITs. Additionally, interdependence is observed for some of the country-pair REITs.

Originality/value

The evidence indicates that REITs markets respond to global events. Thus, the increasing co-movement amongst REITs observed in this study may expose domestic REITs to global crisis. However, this study provides opportunities for minimising the cost of capital for real estate projects. Also, REITs provide limited diversification gains around crisis times. Therefore, countries need to open the REITs markets to global investors whilst pursuing policies to ensure the resilience of the REITs markets to global events. Investors should also take note of the declining geographic diversification gains from some country-pair REITs portfolios.

Abstract

Purpose

This study aims to systematically reveal the complex interaction between uncertainty and the international commodity market (CRB).

Design/methodology/approach

A composite uncertainty index and five categorical uncertainty indices, together with wavelet analysis and detrended cross-correlation analysis, were used. First, in the time-frequency domain, the coherency and lead-lag relationship between uncertainty and the commodity markets were investigated. Furthermore, the transmission direction of the cross-correlation over different lag periods and asymmetry in this cross-correlation under different trends were identified.

Findings

First, there is significant coherency between uncertainties and CRB mainly in the short and medium terms, with natural disaster and public health uncertainties tending to lead CRB. Second, uncertainty impacts CRB more markedly over shorter lag periods, whereas the impact of CRB on uncertainty gradually increases with longer lag periods. Third, the cross-correlation is asymmetric and multifractal under different trends. Finally, from the perspective of lag periods and trends, the interaction of uncertainty with the Chinese commodity market is significantly different from its interaction with CRB.

Originality/value

First, this study comprehensively constructs a composite uncertainty index based on five types of uncertainty. Second, this study provides a scientific perspective on examining the core and diverse interactions between uncertainty and CRB, as achieved by investigating the interactions of CRB with five categorical and composite uncertainties. Third, this study provides a new research framework to enable multiscale analysis of the complex interaction between uncertainty and the commodity markets.

Abstract

Purpose

This study aims to compare the safe-haven properties of different asset markets such as gold, dollar, oil and disaggregated real estate sector (house, plot and residential) against equity returns in Pakistan over the monthly period of January 2011–December 2020.

Design/methodology/approach

The authors use wavelet coherence to encapsulate the overall dependence and correlation of asset classes. Further, the authors also study the potential of diversification at the tail of returns distribution by applying the wavelet value-at-risk (VaR) framework.

Findings

The results of wavelet coherence show that the dependence is weaker (stronger) in the short (long)-term investment horizon. Moreover, the findings of wavelet VaR reveal that the degree of co-movement between gold and equity returns greatly affects the portfolio risk followed by residential property and oil.

Practical implications

The findings are beneficial for the individual investor, fund managers and financial advisors looking for the optimal portfolio combination that hedges the excessive negative movements in equity returns subject to the heterogeneity in the investment horizon.

Originality/value

This is a primary effort to estimate safe-haven investments opportunities at a large spectrum, including disaggregated real estate sector against stock returns in Pakistan. Moreover, this study uses wavelet coherence and wavelet VaR which have an advantage over traditional analysis for diversification.

Abstract

Proposes a new approach for analysing the stationary random response of complex structures located in a non‐homogeneous stochastic field. The approach is a kind of complete CQC method because the cross‐correlation terms between both the participant modes and the ground joint excitations are included in the response calculations. Also takes into account the effect of the loss of coherency between ground joints.

Abstract

A new quantum effect device which is capable of highly coherent electron emission is theoretically proposed and analysed. The new device works by using the potential induced accumulation layer at a heterointerface to produce dimensionally reduced electrons. These electrons tunnel through a heterobarrier ensuring that their energy is quantised in the direction of propagation. To avoid the problem of unquantised three dimensional electrons dominating the current the two dimensional electrons that tunnel through the barrier are replenished by electrons from two side contacts. A self‐consistent model is used to analyse the performance of the device and it is found that the new device performs very well, producing electrons with a very narrow energy spread in the direction of propagation. The current density/coherency combination is easily controlled by the applied bias and the device also offers the potential for ultra fast switching through the transition between coherent and incoherent states.

Abstract

Examines the coherentist project for educational administration of professors Colin Evers and Gabriele Lakomski from a critical and pragmatic perspective. It is argued that Evers and Lakomski really have three projects going: the first project seeks to ground coherence as a solution to the problems of educational administration research upon the history of educational administration inquiry philosophies since the Second World War. The second project attempts to justify the worth of coherency as a research philosophy upon purely logical grounds. A third, and most recent, (practical) project draws upon evidence from leadership practice to prove coherentism’s usefulness for school administration. Concludes that, rather than supporting their post‐positivist philosophic underpinnings, Evers and Lakomski’s third project finds them moving toward a raw pragmatism. Also concludes that coherentism is best redescribed from a pragmatic aesthetic perspective, a point of view that provides a potentially more meaningful way of understanding the relationship of coherentist theorizing and leadership action in contemporary schooling.

Abstract

Purpose

To the best of our knowledge, no study has examined credit cycle synchronizations in the context of emerging economies. Studying the credit cycles synchronization across BRICS (Brazil, Russia, India, China and South Africa) countries is crucial given the magnitude of trade and financial integration among member counties. The enormity of the trade and financial linkages among BRICS countries and growth spillovers from emerging economies to advanced and low-income countries provide the rationale and motivation to study the synchronization of credit cycles across BRICS.

Design/methodology/approach

The study investigates the credit cycles coherence across BRICS economies from 1996Q2 to 2020Q4. The synchronization analysis is done using the noval wavelet approach. The analysis examines not only the coherence but also the extent of credit cycle synchronization that varies across frequencies and over time among different pairs of nations.

Findings

The authors find heterogeneity in the credit cycles' synchronization among the member nations. China and India are very much in sync with the other BRICS countries. China's high-frequency credit cycle mostly leads the other countries' credit cycles before the global financial crisis and shows a mix of lead/lag relationships post-financial crisis. Interestingly, most of the time, India's low-frequency credit cycles lead the member countries' credit cycles, and Brazil's low frequency credit cycle lag behind the other BRICS countries' credit cycles, except for Russia. The results are crucial from the macroprudential policymaker's perspective.

Research limitations/implications

The empirical design is applicable to a similar set of countries and may not directly fit each emerging economy.

Practical implications

The findings will help understand the marked deepening of trade, technology, investment and financial interdependence across the world. BRICS acronym requires no introduction, but such analysis may help understand the interaction at the monetary policy level.

Originality/value

This is the first study that highlights the need to understand the credit variable interactions for BRICS nations.

Abstract

Purpose

The paper examines the impact of COVID-19 on bank stock returns over various time scales and frequencies for 36 countries. Moreover, the authors look at the governments' responses to the corona crisis and examine its impact on bank stock returns.

Design/methodology/approach

The paper applies continuous wavelet transformation to obtain robust estimates of the co-movement (coherency) between confirmed cases and bank stock returns over time and at different time scales. Furthermore, the authors apply fixed effects panel regression to examine the response of bank stocks to domestic COVID-19 policies.

Findings

The results indicate that the number of confirmed COVID-19 cases negatively impacts bank stock returns during different waves of the pandemic in the medium-run. However, there is only little dependence in the very short-run. Moreover, bank stock returns positively react to domestic COVID-19 polices. This demonstrates that governmental interventions not only reduce the spread of COVID-19 but are also able to thereby calm financial markets.

Originality/value

The application of wavelet methods to the field of economics and finance is relatively recent and allows the distinction between short-term and long-term effects. Standard econometric methods, in contrast, only operate within the time domain. This paper combines wavelet methods with conventional econometrics to answer the research question.

Abstract

Purpose

Corrosion loop development is an integral part of the risk-based inspection (RBI) methodology. The corrosion loop approach allows a group of piping to be analyzed simultaneously, thus reducing non-value adding activities by eliminating repetitive degradation mechanism assessment for piping with similar operational and design characteristics. However, the development of the corrosion loop requires rigorous process that involves a considerable amount of engineering man-hours. Moreover, corrosion loop development process is a type of knowledge-intensive work that involves engineering judgement and intuition, causing the output to have high variability. The purpose of this paper is to reduce the amount of time and output variability of corrosion loop development process by utilizing machine learning and group technology method.

Design/methodology/approach

To achieve the research objectives, k-means clustering and non-hierarchical classification model are utilized to construct an algorithm that allows automation and a more effective and efficient corrosion loop development process. A case study is provided to demonstrate the functionality and performance of the corrosion loop development algorithm on an actual piping data set.

Findings

The results show that corrosion loops generated by the algorithm have lower variability and higher coherence than corrosion loops produced by manual work. Additionally, the utilization of the algorithm simplifies the corrosion loop development workflow, which potentially reduces the amount of time required to complete the development. The application of corrosion loop development algorithm is expected to generate a “leaner” overall RBI assessment process.

Research limitations/implications

Although the algorithm allows a part of corrosion loop development workflow to be automated, it is still deemed as necessary to allow the incorporation of the engineer’s expertise, experience and intuition into the algorithm outputs in order to capture tacit knowledge and refine insights generated by the algorithm intelligence.

Practical implications

This study shows that the advancement of Big Data analytics and artificial intelligence can promote the substitution of machines for human labors to conduct highly complex tasks requiring high qualifications and cognitive skills, including inspection and maintenance management area.

Originality/value

This paper discusses the novel way of developing a corrosion loop. The development of corrosion loop is an integral part of the RBI methodology, but it has less attention among scholars in inspection and maintenance-related subjects.
