Bayesian inference for inflation volatility modeling in Ghana
Authors: Korkpoe Carl Hope , Ahiakpor Ferdinand , Amarteifio Edward Nii Amar 
Published: June 2024

PurposeThe purpose of this paper is to emphasize the risks involved in modeling inflation volatility in the context of macroeconomic policy. For countries like Ghana that are always battling economic problems, accurate models are necessary in any modeling endeavor. We estimate volatility taking into account the heteroscedasticity of the model parameters.Design/methodology/approachThe estimations considered the quasi-maximum likelihood-based GARCH, stochastic and Bayesian inference models in estimating the parameters of the inflation volatility.FindingsA comparison of the stochastic volatility and Bayesian inference models reveals that the latter is better at tracking the evolution of month-on-month inflation volatility, thus following closely the data during the period under review.Research limitations/implicationsThe paper looks at the effect of parameter uncertainty of inflation volatility alone while considering the effects of other key variables like interest and exchange rates that affect inflation.Practical implicationsEconomists have battled with accurate modeling and tracking of inflation volatility in Ghana. Where the data is not well-behaved, for example, in developing economies, the stochastic nature of the parameter estimates should be incorporated in the model estimation.Social implicationsEstimating the parameters of inflation volatility models is not enough in a perpetually gyrating economy. The risks of these parameters are needed to completely describe the evolution of volatility especially in developing economies like Ghana.Originality/valueThis work is one of the first to draw the attention of policymakers in Ghana towards the nature of inflation data generated in the economy and the appropriate model for capturing the uncertainty of the model parameters.
DEI in dual-listed mining MNEs: examining rhetoric and reality from a fields perspective
Authors: Sasikala Visalakshy , Sankaranarayanan Venkataraman , Dhayanithy Deepak , Mohan Geetha 
Published: June 2024

Purpose
This paper aims to critically examine how dual-listed multinational enterprises (MNEs) that are embedded across multiple national contexts interact with other actors to shape the diversity, equality and inclusion (DEI) narrative, outcomes and the associated dynamics of social change in the mining industry.

Design/methodology/approach
The authors use data from the publicly available sustainability reports of two global mining conglomerates with dual-listing structure, Rio Tinto and Anglo American, alongside prevalent DEI regulations in the UK, Australia and South Africa to understand how DEI discourse and practice and the corresponding role of key actors have evolved since 2015. The authors combine a case study approach with topic modelling and qualitative content analysis to critically analyse the linkage between actors’ stated posture and actions in their DEI field and their impact upon various exchange relationships within the mining industry exchange field over the period 2015–2021.

Findings
The analysis revealed three broad phases of evolution in the DEI involvement of the MNEs emphasizing on diversity, equality and inclusion, respectively. Both firms progressed at a different pace across the three phases highlighting the need for a systemic perspective when addressing DEI concerns.

Originality/value
This paper is one of the earliest to adopt an issue and exchange field perspective towards examining the complexity of DEI. Taking a critical performative stance, the authors argue that for improving convergence between MNEs’ DEI rhetoric and reality and to advance DEI in new ways organizations and policymakers must devise structural interventions in the DEI field that substantively impact MNEs’ industry exchange field relationships.
Cybersecurity in digital supply chains in the procurement process: introducing the digital supply chain management framework
Authors: Aarland Mari 
Published: June 2024

Purpose
This paper aims to explore the cybersecurity challenges the electric power industry faces due to its increased reliance on digital supply chains (DSCs), focusing on the procurement phase.

Design/methodology/approach
This study uses qualitative methods, with 17 semi-structured interviews conducted among industry participants to delve deep into the challenges and potential solutions. The Gioia methodology was applied to analyse the interview data. The ecosystem and procurement theory is used to understand the interconnectedness and vulnerabilities within the electric power industry’s DSC.

Practical implications
This paper presents a framework to systematically address and mitigate cybersecurity risks in the DSC. Combining theoretical foundations with reasonable measures can significantly enhance cybersecurity resilience. By implementing these guidelines, organisations can foster collaboration across the supply chain, maintain regulatory compliance and continually adapt to the evolving threat landscape.

Originality/value
The paper is based on unique interview data from actors in the electric power industry. It presents a new framework for managing cybersecurity in DSCs, underpinned by the theoretical lenses of ecosystems and procurement.
Risk-adjusted lifetime value: adjusting for customer riskiness using a single metric
Authors: Singh Shweta , Murthi B.P.S. , Rao Ram C. , Steffes Erin 
Published: June 2024

PurposeThe current approach to valuing customers is based on the notion of discounted profit generated by the customers over the lifetime of the relationship, also known as customer lifetime value (CLV). However, in the financial services industry, the customers who contribute the most to the profitability of a firm are also the riskiest customers. If the riskiness of a customer is not considered, firms will overestimate the true value of that customer. This paper proposes a methodology to adjust CLV for different types of risk factors and creates a comprehensive measure of risk-adjusted lifetime value (RALTV).Design/methodology/approachUsing data from a major credit card company, we develop a measure of risk adjusted lifetime value (RALTV) that accounts for diverse types of customer risks. The model is estimated using Stochastic Frontier Analysis (SFA).FindingsMajor findings indicate that rewards cardholders and affinity cardholders tend to score higher within the RALTV framework than non-rewards cardholders and non-affinity cardholders, respectively. Among the four different modes of acquisition, the Internet generates the highest RALTV, followed by direct mail.Originality/valueThis paper not only controls for different types of consumer risks in the financial industry and creates a comprehensive risk-adjusted lifetime value (RALTV) model but also shows empirically the value of using RALTV over CLV for predicting future performance of a set of customers. Further, we investigate the impact of a firm’s acquisition and retention strategies on RALTV. The measure of risk-adjusted lifetime value is invaluable for managers in financial services.
Breaking down barriers: addressing managerial hesitancy towards hiring transgender employees
Authors: Sharma Naman 
Published: June 2024

Purpose
This paper aims to investigate the extent of transgender (TG) inclusivity in workplaces, particularly comparing developed and developing economies. It seeks to address the social stigma faced by TG individuals in Asian economies, notably focusing on India. Through qualitative studies, the research identifies barriers hindering TG employment and proposes a theoretical framework to guide organizations in creating TG-inclusive work environments. The research intends to provide insights that enhance the experiences of TG employees while promoting diversity and inclusion in organizations.

Design/methodology/approach
This research comprises two qualitative studies aimed at first identifying barriers to TG employment through the lens of human resources (HR) professionals and then suggesting a theoretical framework to organizations for overcoming these barriers to achieve a TG-inclusive workplace. Thematic analysis, using Atlas.Ti software, and the interpretive structural modelling technique were used to synthesize a conceptual framework.

Findings
This study's outcomes highlight a substantial gap in achieving truly TG-inclusive workplaces, particularly in economies with prevalent social stigma like India. The findings show that traditional means may not be enough for building a TG-inclusive workplace, and organizations need to go the extra mile by promoting positive deviance and TG-centric corporate social responsibility initiatives to achieve results.

Originality/value
The results of this study provide insights for organizations seeking to improve the experiences of their TG employees and promote diversity and inclusion in the workplace. The incorporation of HR professionals' insights offers a practical perspective, and the conceptual framework proposed for organizations to overcome TG employment barriers is a novel contribution.

Published: June 2024

PurposeThe present study aimed to validate the Indonesian-language version of the psychological capital questionnaire (PCQ), specifically within the context of higher education, by utilising Rasch analysis to evaluate the reliability and validity aspect such as item-fit statistics, rating scale function, and differential item functioning of the instrument. These questionnaires are designed to assess students' initial psychological status, aiming to ease their transition from school to university and monitor undergraduate students' mental health.Design/methodology/approachA total of 1,012 undergraduate students (female = 61.2%; male = 38.8%) from a university in Central Java, Indonesia completed the 24-item Indonesian version of the PCQ. The sampling technique used is quota sampling. Data were analysed using The Rasch model analysis, it was performed using the Winsteps 3.73 software.FindingsThe results of the Rasch analysis indicated that the reliability of the instrument was good (a = 0.80), item quality was excellent (1.00), and person reliability was consistent (0.77). In the validity aspect, all four domains of the PCQ exhibited unidimensionality, and a rating scale with four answer choices was deemed appropriate. The study also identifies item difficulty level in each dimension.Practical implicationsThe practical implications of this study are beneficial for higher education institutions. They can use the validated Indonesian version of the PCQ to monitor the mental well-being of undergraduate students. Mapping the PsyCap can serve as a basis for developing and determining learning policies, potentially leading to improvements in student academic performance. The theoretical implications of this study are related to the advancement of measurement theory. By employing Rasch analysis, the study contributes to enhancing the validity and reliability of measurement, particularly in the context of educational and psychological assessment in Indonesia.Originality/valueThis current study confirmed that the Indonesian version of PCQ adequately measures psychological capital in higher education, particularly in the Indonesian context.
Role of ESG and private equity on environmental degradation: a nexus of opportunity and responsibility for developing and developed countries
Authors: Malik Kunjana , Sharma Sakshi 
Published: June 2024

PurposeAs concerns about global warming and environmental degradation have intensified, researchers are trying to create a deeper understanding of country-specific factors that affect environment so that economic growth can be simultaneously achieved. Recently, private equity (PE) has emerged as a significant form of corporate investment worldwide, compelled to reconcile their financial objectives along with the burgeoning demand for sustainable investment practices. However, the nexus between environmental degradation and PE investment at the country level is yet to be explored.Design/methodology/approachThe study uses annual data for 78 developed countries from 2002 to 2020 and 107 developing countries, which have been divided into 54 lower-middle-income and 53 upper-middle-income countries, to explore the relationship between carbon emission, economic growth and PE investment within an energy growth and Environmental Kuznets curve (EKC) framework.FindingsThe study finds the existence of the EKC hypothesis for developed, upper-middle-income developing and lower-middle-income developing countries. PE investment reduces environmental degradation by providing investments in cleaner technologies, energy-efficient sources and renewable investments. Better human development index (HDI) reduces carbon emissions, as more education and knowledge involve an understanding of environmental protection. Increased climate risk index increases carbon emissions, and therefore, the study provides insights for policymakers and government to enhance PE investments within a country, which will eventually lead to development of sustainable business practices.Originality/valueThe study is the first of its kind to look into the impact of PE as a source of investment on environmental degradation, incorporating economic growth and environmental, social and governance (ESG) factors.

Authors: Boesten Nadine , De Regge Melissa , Eeckloo Kristof , Leys Mark , Gemmel Paul , Meijboom Bert R. 
Published: June 2024

PurposeNurses are capable of acting as advocates for patients since they hold valuable knowledge on patient preferences and their psychosocial needs. Yet, in practice they tend to contribute little to multidisciplinary team meetings (MDTMs). This study analyses the factors that influence whether or not nurses will speak up and increase patient-centred decision-making in MDTMs.Design/methodology/approachA multiple case study with cross-case comparison of twelve tumour groups across two Belgian hospitals was conducted. Data collection involved fifty structured non-participant observations and 41 semi-structured interviews with participants from the twelve tumour groups.Originality/valueThis study yields factors that increase the opportunities for nurses to speak up in MDTMs to enhance patient-centred decision-making. The findings help in the design of future interventions concerning multidisciplinary teamwork, that address nurses’ contributions to augment patient-centred care.
Performative place branding and Brazilian smart cities: the strategic character of smart city positioning
Authors: Couto de Azevedo de Oliveira Renata , Patterson Maurice 
Published: June 2024

Purpose
This paper aims to address what it means to brand a city as “smart”. In other words, what ideas, understandings and actions are mobilized by the discourse of smart cities in a particular context.

Design/methodology/approach
Taking a brand interpretive approach, this paper uses deconstructive criticism to understand the performativity of smart cities within the Brazilian Charter for Smart Cities and to expose hegemonic power structures and the various colonizations that disenfranchise consumers and citizens of the Global South.

Findings
This paper finds that the branding of smart cities within the Brazilian Charter for Smart Cities is largely performative and rhetorical in nature. The authors identify those dimensions of the smart city that are materialized by this branding performance. For example, the authors identify how the Charter calls forth issues around technological solutionism, sustainability and social inclusion. At the same time, the analysis draws attention to the dimensions of smart cities that are disguised by such performances.

Research limitations/implications
The implications of the work suggest that the authors need to understand the designation “smart city” as a branding performance. More research is required in context to determine in exactly what ways smart city projects are being implemented.

Practical implications
Rather than adhering only to the rhetoric of smartness, cities have to work hard to make smartness a reality – a smartness constructed not just on technical solutions but also on human solutions. That is, the complexity of urban issues that are apparently addressed in the move to smartness demand more than a technological fix.

Originality/value
The research offers a novel lens through which to view smart cities.
The opportunity of struggle: a case study on developing a Māori-centric nursing course
Authors: Davis Josephine , Wiapo Coral , Sami Lisa , Komene Ebony , Adams Sue 
Published: June 2024

PurposeThis paper delves into the enduring influence of Linda Tuhiwai Smith’s groundbreaking work, “Decolonizing Methodologies: Research and Indigenous Peoples,” while examining how the concept of “struggle” has facilitated Māori-centric nursing education.Design/methodology/approachUtilizing a case study approach, a collaboration between Māori and non-Māori nursing academics describes the development of two Māori-centric postgraduate courses. This approach allows for an exploration of the contextual factors surrounding sites of “struggle” in course development and efforts towards decolonization and indigenization.FindingsThe evaluation of a Māori-centric postgraduate course is guided by Smith’s five key conditions for “struggle”. By illustrating the dynamic and intersecting nature of these conditions, the study reveals how various interests, tensions and relationships intersect within academia. We further show how the team actively sought viable solutions to strengthen the Maori nursing workforce and those nurses serving Maori communities through the development of tailored courses.Originality/valueThis case study offers a unique perspective on the tensions inherent in the struggles faced by Māori women and their allies, who utilize cultural frameworks as sites of resistance within Western institutions. We highlight how education can carve out new spaces for Māori within their cultural context and the broader academic sphere. Inspired by Smith’s work, this dialogue transcends academic boundaries, echoing the values, knowledge and experiences of Indigenous peoples marginalized by colonialism.
Neighbour‐detection causes shifts in allocation across multiple organs to prepare plants for light competition
Authors: Uyehara Isaac K. , Bechinger Trixie , Jordan Alex , van Kleunen Mark 
Published: June 2024

Abstract

To maximize their fitness, plants have to adjust their allocation strategy according to their abiotic and biotic environments. Plants can use the ratio of red to far‐red light (R:FR) to sense neighbours, allowing them to modify their growth in response to aboveground competition.

In this study, we used supplemental FR light to artificially lower the R:FR of the lower leaves of common sunflowers (Helianthus annuus) to examine how plants change their growth in response to the threat of neighbours. We combined this treatment with a nitrogen fertilization treatment to investigate how responses to neighbour‐detection interact with nitrogen limitation.

Plants grown in low R:FR increased in height at the expense of root growth, resulting in nitrogen limitation that restricted leaf growth. However, we found that plants reduced their nitrogen investment into leaves in low R:FR. By weakening the nitrogen sink strength of these lower leaves before they experienced low photosynthetically active radiation, plants were able to preemptively allocate nitrogen to leaves higher in the canopy.

Plants responded to the perception of neighbours by simultaneously diverting resources from root growth to stem elongation and from leaves threatened by neighbours to leaves that would pose a threat to neighbours. This whole‐plant response to neighbour‐detection enables plants to change their allocation in a way that simultaneously manages their limited nitrogen and prepares them for future light competition.

AbstractThe Great Pacific Garbage Patch, a significant collection of plastic introduced by human activities, provides an ideal environment to study bacterial lifestyles on plastic substrates. We proposed that bacteria colonizing the floating plastic debris would develop strategies to deal with the ultraviolet‐exposed substrate, such as the production of antioxidant pigments. We observed a variety of pigmentation in 67 strains that were directly cultivated from plastic pieces sampled from the Garbage Patch. The genomic analysis of four representative strains, each distinct in taxonomy, revealed multiple pathways for carotenoid production. These pathways include those that produce less common carotenoids and a cluster of photosynthetic genes. This cluster appears to originate from a potentially new species of the Rhodobacteraceae family. This represents the first report of an aerobic anoxygenic photoheterotrophic bacterium from plastic biofilms. Spectral analysis showed that the bacteria actively produce carotenoids, such as beta‐carotene and beta‐cryptoxanthin, and bacteriochlorophyll a. Furthermore, we discovered that the genetic ability to synthesize carotenoids is more common in plastic biofilms than in the surrounding water communities. Our findings suggest that plastic biofilms could be an overlooked source of bacteria‐produced carotenoids, including rare forms. It also suggests that photoreactive molecules might play a crucial role in bacterial biofilm communities in surface water.
