Numerical simulations of a stochastic dynamics leading to cascades and loss of regularity: Applications to fluid turbulence and generation of fractional Gaussian fields
Authors: Beck Geoffrey , Bréhier Charles-Edouard , Chevillard Laurent , Grande Ricardo , Ruffenach Wandrille 
Published: July 2024

Motivated by the modeling of the spatial structure of the velocity field of three-dimensional turbulent flows, and the phenomenology of cascade phenomena, a linear dynamics was recently proposed that can generate high velocity gradients from a smooth-in-space forcing term. It is based on a linear partial differential equation stirred by an additive random forcing term that is δ-correlated in time. The underlying proposed deterministic mechanism corresponds to a transport in Fourier space that aims to transfer energy injected at large scales towards small scales. The key role of the random forcing is to realize these transfers in a statistically homogeneous way. Whereas at finite times and positive viscosity the solutions are smooth, a loss of regularity is observed for the statistically stationary state in the inviscid limit. We present here simulations, based on finite volume methods in the Fourier domain and a splitting method in time, which are more accurate than the pseudospectral simulations. We show that our algorithm is able to reproduce accurately the expected local and statistical structure of the predicted solutions. We conduct numerical simulations in one, two, and three spatial dimensions, and we display the solutions both in physical and Fourier space. We additionally display key statistical quantities such as second-order structure functions and power spectral densities at various viscosities.

Authors: Basher Mohammad Atiqul , Dipto Shahadat Hossain , Rahman Mizanur 
Published: July 2024

Learning outcomes
The primary objective of this case was to grant the students an exposure to the students regarding how to manage a retail business during an economic crisis. In this case, all three of the aforementioned objectives as the students were given opportunity to dissect the business process through business model canvas, find out the key success factors and more importantly, were encouraged towards cost cutting behaviour by presenting the real-life dilemmas that were faced by an actual entrepreneur. Furthermore, the students were shown the importance of stakeholder management through this case, as support is very much needed for the retailers from macro-economic and micro-economic level.

Case overview/synopsis
This case study is the story of Global Gadget Limited, a premium retailer of cell phones and other relevant devises, which is located in Dhaka, the capital city of Bangladesh. The story is revolving around the challenge that Mr Shahadat Hossain Dipto, the owner of Global Gadget is facing over the past two years. Dipto mainly runs his business by selling budget phones from brands like Oppo, Xiaomi, Samsung and Vivo to the middle class and lower middle-class people of Bangladesh, who are very much cost conscious. To persuade these customers to buy his phones, he offers discounts, free gifts, equated monthly instalment services (a monthly instalment plan for the customers who cannot afford to pay the full amount when buying the phone) and sometimes even lottery. In the process, if he can sell more phones, these brands reward him with attractive commissions and all the necessary supports that help him run the business with marginal profit. However, due to the Russia–Ukraine war, he is now in crisis as the resulting economic crisis is causing a price increase on these phones, while drying out his customer’s pockets. This case study is designed to teach the students the importance of product segmentation, inventory management, cost management and relationship management to the students and future entrepreneur, so that they can understand, what does it take for an entrepreneur to survive an economic crisis.

Complexity academic level
This case study is aimed at undergraduate, masters’ students in business schools and Master of Business Administration students or short course executives and for the students of entrepreneurship education programme.

Moderating role of gender diversity in the relationship between intellectual capital efficiency and corporate performance
Authors: Tiwari Ranjit , Arora Akshita 
Published: July 2024

PurposeIn today’s knowledge-based economy, companies are hugely driven by intangible resources such as intellectual capital. However, whether corporate governance of a company drives intellectual capital is less explored in emerging economies. We examine the impact of intellectual capital efficiency on firm performance for Indian firms, considering the moderating role of board gender diversity.Design/methodology/approachWe have created a framework for panel data analysis and conducted estimation using the dynamic panel data model to control for endogeneity and heteroskedasticity issues. We use alternate performance and gender diversity measures for our sample of top 500 listed companies for a period of six years, that is 2015–2020.FindingsThe results demonstrate a significant positive association between intellectual capital and performance. However, moderating impact of gender diversity on the relationship between intellectual capital and performance is not significant.Practical implicationsThe findings indicate that IC plays a crucial role in a company’s performance, which may boost economic growth. Further, the findings reveal that despite the mandatory quota for women on boards in Indian companies, their impact on IC is subliminal. It may be because the critical mass is yet to be achieved, which should be considered by policy-makers while framing policies in this area.Originality/valueOur study is one of the foremost studies to consider the impact of mandatory gender quotas while examining the association between tangible and intangible firm performance. It makes an incremental contribution to literature to enrich our understanding on the influence of gender diversity on intellectual capital-performance linkages.
Exploring virtual facilitation of co-development
Authors: Clottes Heikkilä Heli , Kurki Anna-Leena 
Published: July 2024

Purpose
The purpose of this study is to investigate facilitator’s tools and actions in promoting interaction in virtual co-development.

Design/methodology/approach
In virtual environments, facilitation plays a crucial role. However, research does not provide many examples of tools and practices of virtual facilitation of co-development. To collect data, two virtual co-development processes were conducted. The data consisted of discussions during virtual workshops and was analyzed using both theory- and data-driven content analysis.

Findings
The discussions during the virtual co-development processes related on the topic and script of co-development and the use of digital technology. In co-development, both the facilitators and the participants take responsibility on the topic and the progression of the session. The facilitator needs to balance between offering the participants tools, supporting interaction and leaving empty space for the participants’ initiatives to enhance their agency.

Originality/value
The study underlines the importance of the script and tools in virtual facilitation as well as flexibility in the execution of co-development processes.
Intuiting or rationalising self-other agreement in leadership?
Authors: Curtis Guy J. , Douglas Heather E. 
Published: July 2024

PurposeCongruent self-other agreement in leadership evaluations is associated with positive outcomes such as work unit performance. In contrast, poor self-other agreement in leadership evaluations is associated with negative outcomes such as leaders making ineffective job-relevant decisions. This study examined whether the extent of leaders’ preference for intuitive and rational thinking predicted self-other agreement in leadership evaluations.Design/methodology/approachSelf-ratings and follower ratings of transformational leadership were analysed for 160 dyad pairs of leaders and followers (n = 320). Leaders self-rated their preference for rational and intuitive thinking. Response surface analysis was used to model the relationship between self-other agreement and leaders’ thinking styles.FindingsAs ratings of transformational leadership increased in both leaders and followers, we observed higher scores on preferences for both rational and intuitive thinking. Leaders’ preference for intuitive thinking showed a curvilinear relationship with self-other agreement, such that more intuitive thinking was related to higher leader–follower congruence in ratings of transformational leadership. We further uncovered that higher leader preferences for rational thinking were related to increased leader–follower disagreement in transformational leadership ratings.Originality/valueResearch has focused more on the outcomes than antecedents of self-other agreement in leadership. Thinking styles have undergone limited examination as antecedents of self-other agreement in leadership evaluations. Thinking styles are semi-malleable traits that can be used for the selection of leadership potential and developed to improve leadership performance. The current research suggests that relationships between thinking styles and self-other agreement on leadership effectiveness are more complicated than first thought.
Cholesterol-lowering effect of Pediococcus strains isolated from mother’s milk in mice
Authors: Abdi Milad , Ghanavati Roya , Lohrasbi Vahid , Talebi Malihe 
Published: July 2024

Purpose
The Pediococcus strains belong to the group of lactic acid bacteria (LAB). This study aims to isolate and identify the Pediococcus spp. from mother’s milk, and investigate their tolerance to low pH and bile salts, antibacterial activity, attachment to HT-29 cells and effect on cholesterol-lowering and digestive enzymes in mice.

Design/methodology/approach
Pediococcus species were isolated from mother’s milk, then tested for tolerance to acid and bile salts, their antibacterial effect and attachment to HT-29 cell line. In mice experiment, the levels of triglyceride (TG), total cholesterol (TC), HDL cholesterol (HDL-C), LDL cholesterol (LDL-C) and digestive enzymes such as amylase and lipase in serum of mice were measured after administration of 108 CFU/mL bacterial suspension.

Findings
A total of 24 Pediococcus spp. including 16 isolates of Pediococcus pentosaceus and 8 isolates of Pediococcus acidilactici were isolated. Fifteen isolates (62.5%) were able to survive in low pH and bile salt concentration. Ten isolates (41.6%) exhibited the most powerful inhibitory effects against both Gram-positive and Gram-negative bacterial pathogens. A total of four Pediococcus isolates (16.67%) showed strong attachment to HT-29 cells. In contrast to HDL-C and amylase, the serum levels of TC, TG and LDL-C were reduced and lipase was elevated significantly following administration of mother milk-derived Pediococcus isolates.

Originality/value
The Pediococcus isolates demonstrated good probiotic properties in particular cholesterol-lowering ability in mice. Thus, after more studies they can be considered as probiotic strain(s).
Integration of digital technologies in anti-corruption initiatives in Botswana: lessons from Georgia, Ukraine and South Africa
Authors: Omotoye Abiodun Marumo , Holtzhausen Natasja 
Published: July 2024

Purpose
This paper aims to explore the potential role of digitalization in reshaping Botswana's assets and liabilities declaration system. Digitalization presents opportunities to not only improve efficiencies in how services are delivered and citizens are engaged but also to integrate innovative ways to combat wicked problems such as illicit enrichment and conflicts of interest in the public service.

Design/methodology/approach
This qualitative paper adopts an exploratory research design to investigate how digital technologies can be used to enhance anti-corruption reforms in a developing country context. Primary data, focusing on the shortcomings and successes of Botswana’s asset declaration system, were collected from interviews with key policy actors in Botswana’s anti-corruption landscape, whereas secondary data were drawn from documents such as official reports, news and social media reports and available literature on the topics of digitalization and anti-corruption reforms. A comparative case study approach is used, highlighting successes and challenges in the use of electronic disclosure systems in Georgia, Ukraine and South Africa.

Findings
The analysis provides insights into the potential benefits and challenges associated with the integration of digital technologies in the asset and liability declaration process. The integration of digital technologies in the anti-corruption efforts of Georgia, Ukraine and South Africa has contributed to the development of robust electronic declaration systems. However, political resistance, costs, technical capacity and verification processes are identified as some of the core challenges confronting agencies tasked with implementing asset declaration systems.

Research limitations/implications
The political and socio-economic contexts in the country case studies presented are distinct, as are the challenges posed by corruption. Although Botswana can gain insights from the implementation experiences of Georgia, Ukraine and South Africa, policymakers and implementers need to take into account these subtleties and their potential influence on the success or failure of a similar system. The research has implications for policy and practice by proposing an alternative approach to the implementation of Botswana’s asset declaration system. This will be of interest to policymakers, anti-corruption activists and scholars.

Originality/value
To the best of the authors’ knowledge, prior research has not studied the relationship between digitalization and anti-corruption reforms in Botswana. This paper contributes to the dearth of knowledge regarding the role of digitalization as a driver of anti-corruption reforms. The paper informs policy decisions related to the implementation of digital transformation initiatives in line with Botswana’s anti-corruption and digital transformation agendas.
Assessment of communicative competence in adult patients with minimum response in intensive care units: A scoping review
Authors: Pinto Ana , Lima Mariely , Simões João Lindo 
Published: July 2024

AbstractBackgroundFew formal instruments exist to assess the communicative competence of patients hospitalized in intensive care units (ICUs). This can limit interventions by health professionals.AimsTo map the categories and instruments for assessing the communicative competence of adult patients with minimal response in ICUs.Methods & ProceduresA scoping review was carried out following the Joanna Briggs Institute protocol between February and March 2022 and using the MEDLINE (PubMed), Scopus, Scielo, Business Source Complete (via EBSCOhost), Academic Search Complete (via EBSCOhost) and Web of Science databases, in Portuguese, English and Spanish.Main ContributionEight studies met the inclusion criteria. The different communication and pain assessment protocols covered awareness, cognition, sensory capacity, motor capacity, language, speech and literacy.Conclusions & ImplicationsThe present review offers a starting point for the construction of a formal assessment instrument to enable clinicians to implement an augmentative or alternative communication system (AACS) for the voluntary, independent and active participation of patients.WHAT THIS PAPER ADDSWhat is already known on the subject
Patients in ICUs are subject to various forms of treatment and continuous and intensive monitoring, compromising their capacity to communicate and actively participate (e.g., sharing symptoms and making decisions). Although there is some awareness of their disadvantage in such a regard, few protocols of assessment of communicative competence have been adapted to patients with a minimum response.What this paper adds to the existing knowledge
The present review highlights different protocols for the assessment of communication and pain. They include the following categories: awareness, sensory capacity, auditory and visual acuity, positioning and motor capacity, language, speech, and literacy. The review offers a starting point for the construction of a formal assessment instrument encompassing the aforementioned categories, along with duly validated guidelines for its application.What are the potential or actual clinical implications of this work?
Our formal assessment instrument takes into account the need to adapt to different patient profiles. It is hoped that it will provide speech therapists and other health professionals with the information required to implement an AACS in which patients participate actively.
The barriers to and facilitators of academic and social success for deafblind children and young people: A scoping review
Authors: Manford Claire , Rajasingam Saima , Allen Peter M. , Beukes Eldre 
Published: July 2024

AbstractDeafblind children and young people often perform poorly in education and social settings. The extent of this attainment gap is unknown. Following the Joanna Briggs protocol, a scoping review was conducted with the aim of establishing the barriers to and facilitators of academic and social success for this cohort. A database search was conducted seeking peer‐reviewed studies relating to deafblind children and young people, in academic and social settings, from any country, published in English, between 1989 and 2022. The review included 38 articles with a range of methodological approaches. The main barriers to success were limited opportunities and options to communicate, a lack of awareness of deafblindness within schools and the wider community, and limited opportunities and adaptations to the curriculum, resources and the environment. The facilitators included improving access to communication and resources, increased awareness, and collaboration between families and professionals. Additional research is needed in this field, particularly to investigate the impact of modern technology to aid access and communication for deafblind children and young people.

AbstractAimTo modify the Australian and New Zealand Health Star Rating to account for ultra‐processing and compare the alignment of the modified ratings with NOVA classifications and the current Australian Dietary Guidelines classifications of core (recommended foods) and discretionary (foods to limit).MethodsData was cross‐sectionally analysed for 25 486 products. Four approaches were compared to the original Health Star Rating: (1) five ‘negative’ points added to ultra‐processed products (modification 1; inclusion approach); (2) ultra‐processed products restricted to a maximum of 3.0 Health Stars (modification 2; capping approach); (3 and 4) same approach used for modifications 1 and 2 but only applied to products that already exceeded 10 ‘negative’ points from existing Health Star Rating attributes (modifications 3 and 4, respectively; hybrid approaches). Alignment occurred when products (i) received <3.5 Health Stars and were NOVA group 4 (for NOVA comparison) or discretionary (for Dietary Guidelines comparison), or (ii) received ≥3.5 Health Stars and were NOVA groups 1–3 or core.ResultsAll Health Star Rating modifications resulted in greater alignment with NOVA (ranging from 69% to 88%) compared to the original Health Star Rating (66%). None of the modifications resulted in greater alignment to the Dietary Guidelines classifications overall (69% to 76%, compared with 77% for the original Health Star Rating), but alignment varied considerably by food category.ConclusionsIf ultra‐processing were incorporated into the Australian and New Zealand Health Star Rating, consideration of ultra‐processing within the broader dietary guidance framework would be essential to ensure coherent dietary messaging to Australians.

AbstractAimsThe aim of this study was to measure trajectories of craving for methamphetamine during the course of pharmacotherapy trials for methamphetamine use disorder.Design, setting and participantsCraving trajectories were identified using Group‐Based Trajectory Modeling. The association of craving trajectories with drug use trajectories was examined using a dual trajectory model. Association of craving trajectories with other health and social outcomes was also examined. The study used pooled data from five randomized controlled pharmacotherapy trials for methamphetamine use disorder. A total of 866 adults with methamphetamine use disorder participated in randomized controlled pharmacotherapy trials.MeasurementCraving was assessed weekly using the Brief Substance Craving Scale. Drug use was assessed using urine toxicology. Alcohol‐ and drug‐related problems, as well as psychiatric, medical, legal, employment and relationship problems, were measured using the Addiction Severity Index.FindingsA three‐trajectory model with high, medium and low craving trajectories was selected as the most parsimonious model. Craving trajectories were associated with methamphetamine use trajectories in the course of trial; 88.4% of those in the high craving trajectory group had a consistently high frequency of methamphetamine use compared with 18.7% of those in the low craving group. High craving was also associated with less improvement in most other outcomes and higher rate of dropout from treatment. In turn, low craving was associated with a rapidly decreasing frequency of methamphetamine use, greater improvement in most other outcomes and a lower rate of dropout. Participants on modafinil daily and ondansetron 1 mg twice daily were less likely to be in the high craving group compared with those on placebo.ConclusionsTrajectories of methamphetamine craving in the course of clinical trials for methamphetamine use disorder appear to be both highly variable and strongly associated with greater frequency of drug use, other drug‐related outcomes and dropout from trials. Two medications, modafinil daily and ondansetron at a dose of 1 mg two times daily, appear to be associated with greater reduction in craving in the course of treatment compared with placebo. A decrease in methamphetamine craving shows promise as an early indicator of recovery from methamphetamine use disorder.
