Thermal performance improvement in wavy microchannels using secondary channels
Authors: Paramanandam Karthikeyan , S Venkatachalapathy , Srinivasan Balamurugan , P V R Nanda Kishore 
Published: February 2024

Purpose
This study aims to minimize the pressure drop across wavy microchannels using secondary branches without compromising its capacity to transfer the heat. The impact of secondary flows on the pressure drop and heat transfer capabilities at different Reynolds numbers are investigated numerically for different wavy microchannels. Finally, different channels are evaluated using performance evaluation criteria to determine their effectiveness.

Design/methodology/approach
To investigate the flow and heat transfer capabilities in wavy microchannels having secondary branches, a 3D conjugate heat transfer model based on finite volume method is used. In conventional wavy microchannel, secondary branches are introduced at crest and trough locations. For the numerical simulation, a single symmetrical channel is used to minimize computational time and resources and the flow within the channels remains single-phase and laminar.

Findings
The findings indicate that the suggested secondary channels notably improve heat transfer and decrease pressure drop within the channels. At lower flow rates, the secondary channels demonstrate superior performance in terms of heat transfer. However, the performance declines as the flow rate increased. With the same amplitude and wavelength, the introduction of secondary channels reduces the pressure drop compared with conventional wavy channels. Due to the presence of secondary channels, the flow splits from the main channel, and part of the core flow gets diverted into the secondary channel as the flow takes the path of minimum resistance. Due to this flow split, the core velocity is reduced. An increase in flow area helps in reducing pressure drop.

Practical implications
Many complex and intricate microchannels are proposed by the researchers to augment heat dissipation. There are challenges in the fabrication of microchannels, such as surface finish and achieving the required dimensions. However, due to the recent developments in metal additive manufacturing and microfabrication techniques, the complex shapes proposed in this paper are feasible to fabricate.

Originality/value
Wavy channels are widely used in heat transfer and micro-fluidics applications. The proposed wavy microchannels with secondary channels are different when compared to conventional wavy channels and can be used practically to solve thermal challenges. They help achieve a lower pressure drop in wavy microchannels without compromising heat transfer performance.

PurposeThe purpose of this study is to examine the extent to which promoting sense of community moderates the relationship between servant leadership style and socially responsible leadership (SRL) of public universities in Uganda.Design/methodology/approachThe study adopted cross-sectional survey design to collect data at one point in time using self-administered questionnaires from 214 respondents to examine the relationship between servant leadership and socially responsible leadership with promoting sense of community as a moderator. The study used statistical package for social scientists (SPSS) PROCESS MACRO to establish clusters among the surveyed public universities and later a model was derived.FindingsThe study found a significant moderating effect of promoting sense of community on servant leadership and socially responsible leadership. Implying that investment in promoting sense of community creates awareness about the socially responsible leadership in public universities.Practical implicationsManagers of public universities need to pay keen interest in promoting sense of community to boost socially responsible leadership by building a strong servant leadership style through promoting sense of community for senior managers and leaders especially heads of departments, faculty deans and principals in public universities.Originality/valueThis study contributes to socially responsible leadership literature by advancing the idea that SRL is an important resource that enhances through instituting servant leadership and promoting sense of community in a complex environment. Ideally, servant leadership and promoting sense of community is one of the drivers of customer value, efficiency and effectiveness of public universities.
Advancing women to leadership in academia: does personal branding matter?

Published: February 2024

PurposePersonal branding is a strategic tool of marketing and communication to define success in organisations. While it constitutes a conscious attempt to commodify self and audit self, it must be intentionally managed to obtain its optimum results. This study aims to illustrate how personal branding may also pose unintentional and unconscious strategic tool for women academics in academia to help them get wider visibility and increase their chances of getting into leadership positions.Design/methodology/approachWe employed a case study approach and convenience sampling to select our unit of analysis. Three universities in both public and private universities in the eastern regions of Indonesia were purposefully selected, and interviews were held with 30 female leaders occupying and occupied middle and lower leadership hierarchies.FindingsOur research shows that, despite their unintentional, unplanned and poorly designed personal branding, women have been able to advance to their current leadership positions by building their own rooms for practising their own preferred leadership values to get them visible and heard. This way is performed through a gendered networking, previous leadership experience and bureaucratic requirements. The consequence of such a practice may limit the range of visibility to getting noticed as worthy individuals for senior leadership roles. This might be one reason why women are scarcely found in senior leadership positions.Originality/valueWe propose that natural strategies of constructing, narrating and marketing or communicating personal branding in academia through authentic actions can also be helpful for the success of women to get to leadership roles in a smaller and ambient environment.

Published: February 2024

Purpose
This study aims to examine the linkages between digitalisation, public service delivery and corruption in Ghana using survey data from 121 respondents in Ghana. The authors also examine the mediating role public service delivery offers on corruption.

Design/methodology/approach
This study relied on the capability theory as its theoretical lens and partial least squares structural equation modelling (PLS-SEM) as the data analysis technique.

Findings
Results from the PLS-SEM analysis show that public service delivery significantly reduces corruption, whilst digitalisation does not. However, public service delivery significantly mediated the relationship between digitalisation and corruption.

Research limitations/implications
This study’s limitation is that the data was collected from Ghana only. To enhance the generalisability of findings, future research could collect data from multiple countries. In addition, the study did not factor in the moderating effects of demographic variables such as information and communication technology (ICT) literacy. Future research could consider these variables, given the low ICT literacy level of individuals in developing countries. Finally, future researchers could triangulate results with interviews and focus groups to provide more value to the identified questionnaire-based data.

Practical implications
The findings of this study highlight the need for digitalisation to be included in Ghana’s national policy objectives and service delivery objectives. It is essential for the government to ensure broader public engagement with stakeholders, including citizens, to ensure that digitalisation goals are achieved. The study’s results indicate that digitalisation does not significantly influence corruption. This calls for the government of Ghana to consider raising the level of human capital for the successful planning and deployment of e-services. This includes raising citizen ICT literacy and adopting cutting-edge technology to fully realize the benefits of online services. Developing capabilities, e-government leadership, and public sector employees as enablers of online public services should go hand-in-hand. It is also important to build connected capacities in the country and enhance access to information and technology, along with increasing digital infrastructure.

Originality/value
To the best of the authors’ knowledge, this is the first study to examine and offer a dual perspective on the role of digitalisation on public service delivery and corruption whilst considering the mediating role public service delivery offers on corruption.
Bankruptcy in the UK: Do Managers Talk the Talk Before Walking the Walk?
Authors: Ahmed Yousry , Elsayed Mohamed , Xu Bin 
Published: February 2024

AbstractThis study examines whether managers employ annual report textual disclosures as a conduit to communicate the probability of future corporate bankruptcy or to intentionally mislead stakeholders owing to impression management incentives. We conduct various examinations around the information content of the tone conveyed by textual disclosures in unstructured UK annual reports and the probability of corporate bankruptcy. We document that firms that communicate a more net positive tone are associated with lower bankruptcy risk. Importantly, this association is found to be stronger for firms whose managers have a lower incentive to mislead investors owing to better board monitoring, stringent stock market regulation, and Big 4 audits. We also offer complementary evidence that firms conveying a more net positive tone exhibit higher future performance and earnings persistence, and lower future performance volatility. These firms are also less likely to exhibit extreme corporate policies and to receive a qualified auditor's opinion. Overall, this study sheds light on whether managers tend to inform or misinform (bury their heads in the sand) about corporate bankruptcy.

AbstractObjectiveClinical practice guidelines (CPGs) are an important tool for the management of children with sepsis. The quality, consistency and concordance of Australian and New Zealand (ANZ) childhood sepsis CPGs with the Australian Commission on Safety and Quality in Healthcare (ACSQHC) sepsis clinical care standards and international sepsis guidelines is unclear.MethodsWe accessed childhood sepsis CPGs for all ANZ states and territories through Paediatric Research in Emergency Departments International Collaborative members. The guidelines were assessed for quality using the AGREE‐II instrument. Consistency between CPG treatment recommendations was assessed, as was concordance with the ACSQHC sepsis clinical care standards and international sepsis guidelines.ResultsOverall, eight CPGs were identified and assessed. CPGs used a narrative and pathway format, with those using both having the highest quality overall. CPG quality was highest for description of scope and clarity of presentation, and lowest for editorial independence. Consistency between guidelines for initial treatment recommendations was poor, with substantial variation in the choice and urgency of empiric antimicrobial administration; the choice, volume and urgency of fluid resuscitation; and the choice of first‐line vasoactive agent. Most CPGs were concordant with time‐critical components of the ACSQHC sepsis clinical care standard, although few addressed post‐acute care. Concordance with international sepsis guidelines was poor.ConclusionChildhood sepsis CPGs in current use in ANZ are of variable quality and lack consistency with key treatment recommendations. CPGs are concordant with the ACSQHC care standard, but not with international sepsis guidelines. A bi‐national sepsis CPG may reduce unnecessary variation in care.

AbstractNigella sativa is one of the nutraceuticals that has gained popularity and studied extensively in recent decades as it is considered a safe medicinal plant for use as a dietary supplement. N. sativa contains a wide variety of bioactive substances, which include polyphenols, volatile oils (thymoquinone and p‐cymene), proteins, and peptides. The biological attributes of N. sativa include antioxidant, antimicrobial, antifungal, anti‐inflammatory, anticancer, antidiabetic, antihypertensive, hypolipidemic, and antioxidant activities, which have potential applications for the prevention of a variety of chronic diseases. In the food industry, N. sativa improves the sensory qualities, shelf life, strength, and freshness of foods, such as bread, pizza, biscuits, cookies, and cakes. This review discusses the industrial use of N. sativa, which includes processing technologies to enhance its health‐promoting properties as well as the isolation of nutraceutical components.

AbstractHistones serve as a major carrier of epigenetic information in the form of post‐translational modifications which are vital for controlling gene expression, maintaining cell identity, and ensuring proper cellular function. Loss of histones in the aging genome can drastically impact the epigenetic landscape of the cell leading to altered chromatin structure and changes in gene expression profiles. In this study, we investigated the impact of age‐related changes on histone levels and histone acetylation in the retinal pigment epithelium (RPE) and retina of mice. We observed a global reduction of histones H1, H2A, H2B, H3, and H4 in aged RPE/choroid but not in the neural retina. Transcriptomic analyses revealed significant downregulation of histones in aged RPE/choroid including crucial elements of the histone locus body (HLB) complex involved in histone pre‐mRNA processing. Knockdown of HINFP, a key HLB component, in human RPE cells induced histone loss, senescence, and the upregulation of senescence‐associated secretory phenotype (SASP) markers. Replicative senescence and chronological aging in human RPE cells similarly resulted in progressive histone loss and acquisition of the SASP. Immunostaining of human retina sections revealed histone loss in RPE with age. Acetyl‐histone profiling in aged mouse RPE/choroid revealed a specific molecular signature with loss of global acetyl‐histone levels, including H3K14ac, H3K56ac, and H4K16ac marks. These findings strongly demonstrate histone loss as a unique feature of RPE aging and provide critical insights into the potential mechanisms linking histone dynamics, cellular senescence, and aging.

Published: February 2024

AbstractBackground and AimsNon‐alcoholic beverages (NABs) that mimic alcohol without inducing intoxication, such as non‐alcoholic beers, non‐alcoholic wines and spirit‐free drinks, are increasing in popularity. It is unknown whether NABs help to mitigate or stimulate alcohol use. The present study aimed to describe NAB consumption practices among US adults consuming alcohol, characterize who is likely to consume NABs and examine whether NAB use influences desire for and perceived consumption of alcohol.Design and ParticipantsThe survey study used data collected June–July 2023 from an on‐line convenience sample. The first survey (n = 1906) assessed frequency of NAB consumption among US adults who consume alcohol. A second more detailed survey on use patterns was conducted with 466 respondents who reported past‐year NAB consumption, of whom 153 (32.83%) screened positive on the CAGE questionnaire for alcohol use disorder (AUD).SettingThis study took place in the United States.MeasurementsNAB consumption measures included type of NAB consumed, frequency, quantity, first consumption age, consumption reasons, consumption contexts and perceived effect on desire for and consumption of alcohol. Alcohol use measures included frequency, quantity and first consumption age.FindingsPast‐year NAB use was endorsed by 28.44% of respondents (61.70% ever used). Non‐alcoholic liquor/‘mocktails’ were the most common NAB type consumed (83.69%). Compared with respondents without AUD, those who screened positive for AUD were significantly more likely to consume NABs in an effort to decrease or abstain from drinking alcohol [adjusted odds ratio (AOR) = 3.54, 95% confidence interval (CI) = 2.24–5.58] and 67.97% endorsed less alcohol consumption (3.23% endorsed more) due to their NAB use. NAB consumption frequency and quantity were significantly positively predicted by alcohol consumption frequency (AOR = 1.46, 95% CI = 1.17–1.83) and quantity (β = 0.25, 95% CI = 0.15–0.35), respectively.ConclusionAdults who consume alcohol and screen positive for alcohol use disorder report drinking non‐alcoholic beverages as a harm reduction strategy.
‘It sort of broke me’: A thematic analysis of the psychological experiences and coping strategies employed by Australian fire‐affected farmers
Authors: van der Kruk Shannen R , Gunn Kate M 
Published: February 2024

AbstractIntroductionPeople exposed to bushfires are known to be at heightened risk of experiencing mental health challenges. When farms are impacted, farmers often risk losing not only their homes but also their businesses, containing their livestock, infrastructure and identities.ObjectiveTo understand the psychological experiences of farmers who have been exposed to fires on their farms and identify the coping strategies they already employ to recover and prepare psychologically for future bushfires.DesignIn‐depth, semi‐structured interviews were conducted face‐to‐face or via Zoom. Thematic analysis was used to analyse the data, using a descriptive, essentialist approach. Sixteen farmers and/or their spouses (50% female; median age of 50.8 years), who owned and/or played an active role in the operation of a farming or pastoral enterprise and had been affected by a farm fire within the last 20 years, participated. Participants resided in inner regional, outer regional and remote South Australia and New South Wales.FindingsSeven overarching themes and 22 subthemes resulted: (1) intense emotions in the aftermath, (2) long‐term psychological challenges, (3) deliberate focus on organising, prioritising and completing recovery‐focused tasks, (4) importance of seeking and/or accessing support to rebuild, (5) adopting a positive attitude and outlook, (6) (dis)engaging from/with community and social connection and (7) various strategies employed to self‐regulate emotions.Discussion/ConclusionThis study demonstrates the unique set of psychological challenges Australian farmers experience in the wake of a farm fire and the coping strategies they report using to help them manage. Findings will inform the development of contextually and culturally appropriate bushfire recovery and preparedness initiatives that are tailored to meet the unique needs of farmers and build upon their existing strengths.

AbstractAimTo determine if children with neonatal cholestatic liver disease had concurrent and later findings on brain imaging studies that could be attributed and the cholestasis to contribute to the understanding of the impaired neuropsychological development.MethodsOvid MEDLINE and EMBASE were searched on July 21, 2022, and updated on March 26, 2023. Studies with children under 18 years of age with neonatal cholestasis and a brain scan at the time of diagnosis or later in life were included. Excluded studies were non‐English, non‐human, reviews or conference abstracts. Data were extracted on demographics, brain imaging findings, treatment and outcome. The results were summarised by disease categories. Risk of bias was assessed using JBI critical appraisal tools.ResultsThe search yielded 12 011 reports, of which 1261 underwent full text review and 89 were eligible for inclusion. Haemorrhage was the most common finding, especially in children with bile duct obstruction, including biliary atresia. Some findings were resolved after liver transplantation.ConclusionChildren with neonatal cholestasis had changes in brain imaging, which might play a role in impaired neuropsychological development, but longitudinal clinical research with structured assessment is needed to better qualify the aetiology of the impairment.
