Analysis of current distribution and termination conditions in 2D metasurfaces
Authors: Barmada Sami , Fontana Nunzia , Sandrolini Leonardo , Simonazzi Mattia 
Published: April 2024

Purpose
The purpose of this paper is to gain a better understanding on how metasurfaces behave, in terms of currents in each unit cell. A better knowledge of their behavior could lead to an ad-hoc design for specific applications.

Design/methodology/approach
The methodology used is both theoretical and numerical; it is based on circuit theory and on an optimization procedure.

Findings
The results show that when the knowledge of the current in each unit cell of a metasurface is needed, the most common approximations currently used are often not accurate. Furthermore, a procedure for the termination of a metasurface, with application-driven goals, is given.

Originality/value
This paper investigates the distribution of the currents in a 2D metamaterial realized with magnetically coupled resonant coils. Different models for the analysis of these structures are illustrated, and the effects of the approximations they introduce on the current values are shown and discussed. Furthermore, proper terminations of the resonators on the boundaries have been investigated by implementing a numerical optimization procedure with the purpose of achieving a uniform distribution of the resonator currents. The results show that the behavior of a metasurface (in terms of currents in each single resonator) depends on different properties; as a consequence, their design is not a trivial task and is dependent on the specific applications they are designed for. A design strategy, with lumped impedance termination, is here proposed.
“No, my name’s not on the lease at all”: an interpretive phenomenological analysis of unstable housing and hepatitis C among people who inject drugs
Authors: McColl Roisin , Higgs Peter , Harney Brendan 
Published: April 2024

Purpose
Globally, hepatitis C treatment uptake is lower among people who are homeless or unstably housed compared to those who are housed. Understanding and addressing this is essential to ensure no one is left behind in hepatitis C elimination efforts. This study aims to explore peoples’ experiences of unstable housing and health care, and how these experiences influenced engagement in hepatitis C treatment.

Design/methodology/approach
Purposive sampling was used to recruit people with lived experience of injection drug use, hepatitis C and unstable housing in Melbourne, Australia. In-depth semistructured interviews were conducted and a case study approach with interpretative phenomenological analysis was used to identify personal experiential themes and group experiential themes.

Findings
Four people were interviewed. The precarious nature of housing for women who inject drugs was a group experiential theme, however, this did not appear to be a direct barrier to hepatitis C treatment. Rather, competing priorities, including caregiving, were personal experiential themes and these created barriers to treatment. Another group experiential theme was “right place, right time, right people” with these three elements required to facilitate hepatitis C treatment.

Originality/value
There is limited research providing in-depth insight into how personal experiences with unstable housing and health care shape engagement with hepatitis C treatment. The analyses indicate there is a need to move beyond a “one size fits-all” approach to hepatitis C care. Instead, care should be tailored to the needs of individuals and their personal circumstances and regularly facilitated. This includes giving greater attention to gender in intervention design and evaluation, and research more broadly.

Published: April 2024

Purpose
The library and information science profession finds itself grappling with substantial difficulties and hurdles when addressing the trustworthiness and accuracy of information disseminated through social media platforms. This study aims to highlight the educational authority of librarians and propose a framework for librarians to establish their identity, understand the meaning behind their practice and integrate their expertise through knowledge practices, ensuring their relevance and effectiveness in the social media environment.

Design/methodology/approach
This study delves into a conceptual framework rooted in philosophical inquiry, seeking to establish a harmonious connection between interrelated concepts of civic roles, professional identity and knowledge practices. It draws upon both original research findings and a review of existing literature in the field.

Findings
Civic responsibilities reflect the professional identities of librarians. Evidence of knowledge practices collected from scientific literature emerged to be the important characterization of how librarians uphold their image as educational authorities. It describes the meaning of civic roles and professional practice.

Practical implications
The study sheds light on how librarians maintain their reputation as educators and the knowledge practices that underpin their civic responsibilities amidst the pervasiveness of information disorders.

Originality/value
The framework presented in the study offers a timely and relevant contribution to the complex realm of social media information disorders, a challenge that librarians grapple with regularly. It highlights the emerging role of librarians in society to assert their identity and recognize their civic responsibility in addressing this pressing issue that society faces.
How do people search for knowledge? Ask-directed searching and browsing strategies in professional virtual communities
Authors: Lai Hui-Min , Hung Shin-Yuan , Yen David C. 
Published: April 2024

PurposeSeekers who visit professional virtual communities (PVCs) are usually motivated by knowledge-seeking, which is a complex cognitive process. How do seekers search for knowledge, and how is their search linked to prior knowledge or PVC situation factors? From the cognitive process and interactional psychology perspectives, this study investigated the three-way interactions between seekers’ expertise, task complexity, and perceptions of PVC features (i.e. knowledge quality and system quality) on knowledge-seeking strategies and resultant outcomes.Design/methodology/approachA field experiment was conducted with 119 seekers in a PVC using a 2 × 2 factorial design of seekers’ expertise (i.e. expert versus novice) and task complexity (i.e. low versus high).FindingsThe study reveals three significant insights: (1) For a high-complexity task, experts adopt an ask-directed searching strategy compared to novices, whereas novices adopt a browsing strategy; (2) For a high-complexity task, experts who perceive a high system quality are more likely than novices to adopt an ask-directed searching strategy; and (3) Task completion time and task quality are associated with the adoption of ask-directed searching strategies, whereas knowledge seekers’ satisfaction is more associated with the adoption of browsing strategy.Originality/valueWe draw on the perspectives of cognitive process and interactional psychology to explore potential two- and three-way interactions of seekers’ expertise, task complexity, and PVC features on the adoption of knowledge-seeking strategies in a PVC context. Our findings provide deep insights into seekers’ behavior in a PVC, given the popularity of the search for knowledge in PVCs.

Authors: Almeida Daniel Werner Lima Souza de , Pimenta Júnior Tabajara , Gaio Luiz Eduardo , Lima Fabiano Guasti 
Published: April 2024

PurposeThis study aims to evaluate the presence of abnormal returns due to stock splits or reverse stock splits in the Brazilian capital market context.Design/methodology/approachThe event study technique was used on data from 518 events that occurred in a 30-year period (1987–2016), comprising 167 stock splits and 351 reverse stock splits.FindingsThe results revealed the occurrence of abnormal returns around the time the shares began trading stock splits or reverse stock splits at a statistical significance level of 5%. The main conclusion is that stock split and reverse stock split operations represent opportunities for extraordinary gains and may serve as a reference for investment strategies in the Brazilian stock market.Originality/valueThis study innovates by including reverse stock splits, as the existing literature focuses on stock splits, and by testing two distinct “zero” dates that of the ordinary general meeting that approved the share alteration and the “ex” date of the alteration, when the shares were effectively traded, reverse split or split.
Dashed hopes or delayed met expectations? Skilled migrant women’s qualification-matched employment
Authors: Tharenou Phyllis 
Published: April 2024

PurposeSkilled migrant (SM) women play a key role in developed countries especially in healthcare and education in easing staffing shortages and migrate expecting to gain qualification-matched employment (QME). The aim of this review is to assess whether SM women gain the anticipated QME, equitably compared to their skilled counterparts and to examine why and how they do so.Design/methodology/approachI conducted a systematic literature review to derive empirical studies to assess if, why and how SM women achieve QME (1) using SM women-only samples and comparative samples including SM women, and (2) examining whether they gain QME directly on or soon after migration or indirectly over time through undertaking alternative, contingent paths.FindingsOnly a minority of SM women achieve the anticipated QME directly soon after migration and less often than their skilled counterparts. Explaining the mechanism for achieving QME, other women, especially due to having young families, indirectly undertake alternative, lower-level contingent paths enabling them to ascend later to QME.Originality/valueThe SM literature gains new knowledge from revealing how SM women can gain positions post-migration comparable to their pre-migration qualifications through undertaking the alternative, contingent paths of steppingstone jobs and academic study, especially as part of agreed familial strategies. This review results in a theoretical mechanism (mediation by a developmental contingency path) to provide an alternative mechanism by which SM women achieve QME.
US technological statecraft towards China
Authors: Deligöz Halil 
Published: April 2024

Purpose
This study aims to define a “technological statecraft” concept to distinguish tech-based measures/sanctions from an array of economic measures ranging from restrictions of rare earth elements and natural gas supplies to asset freezes under the wider portfolio of economic statecraft. This concept is practically intended to reveal the USA’s “logic of choice” in its employment of technology as an efficient instrument to deal with China in the context of the great power rivalry.

Design/methodology/approach
This study follows David A. Baldwin’s statecraft definition and conceptualization methodology, which relies on “means” rather than “ends.” In addition to Baldwin and as an incremental contribution to his economic statecraft analysis, this study also combines national political economy with statecraft analysis with a particular focus on the utilization of technological measures against China during the Trump administration.

Findings
The US rationale for choosing technology, namely, emerging and foundational technologies, in its rivalry against China is caused at least by two factors: the nature of the external challenge and the characteristics of the US innovation model based largely on radical innovations. To deal with China, the USA practically distinguished the role of advanced technology and followed a grammer of technological statecraft as depicted in the promulgated legal texts during the Trump administration.

Originality/value
Despite a growing volume of literature on economic statecraft and technological competition, studies focusing on countries’ “logic of choice” with regard to why and under what conditions they choose financial, technological or commodity-based sanctions/measures/controls are lacking. Inspired from Baldwin’s account on the “logic of choice” from among alternative statecrafts (i.e. diplomacy, military, economic statecraft, and propaganda). This study will contribute to the literature with a clear lens to demonstrate the “logic of choice” from among a variety of economic statecraft measures in the case of the US technological statecraft toward China.
Towards equitable leadership development: active ingredients of a culturally responsive program for Black community leaders
Authors: Fix Rebecca L. , Cooper Lisa A. 
Published: April 2024

PurposeThe current study evaluated (1) characteristics of the community leadership development program associated with successful participant recruitment, (2) active ingredients that promoted fellow engagement and program completion and (3) how the program addressed blackness and racism.Design/methodology/approachIndividual interviews were conducted with a representative subset of former program fellows.FindingsResults indicated that offering training in small cohorts and matching fellows with individual mentors promoted program interest. Program strengths and unique ingredients included that the program was primarily led by people from the Black community, program malleability, and that the program was a partnership between fellows and leadership. Additionally, the program was responsive to fellows’ needs such as by adding a self-care component. Fellows also noted dedicated space and time to discuss race and racism. Results offer a unique theoretical perspective to guide leadership development away from the uniform or standardized approach and toward one that fosters diversity and equity in leadership.Originality/valueAltogether, this work demonstrates how leadership development programs can be participant-informed and adapted to participants’ social and cultural needs.
Impact of the variability of material constitutive models on the thermal response of reinforced concrete walls
Authors: Karaki Ghada , Hawileh Rami A. , Naser M.Z. 
Published: April 2024

PurposeThis study examines the effect of temperature-dependent material models for normal-strength (NSC) and high-strength concrete (HSC) on the thermal analysis of reinforced concrete (RC) walls.Design/methodology/approachThe study performs an one-at-a-time (OAT) sensitivity analysis to assess the impact of variables defining the constitutive and parametric fire models on the wall's thermal response. Moreover, it extends the sensitivity analysis to a variance-based analysis to assess the effect of constitutive model type, fire model type and constitutive model uncertainty on the RC wall's thermal response variance. The study determines the wall’s thermal behaviour reliability considering the different constitutive models and their uncertainty.FindingsIt is found that the impact of the variability in concrete’s conductivity is determined by its temperature-dependent model, which differs for NSC and HSC. Therefore, more testing and improving material modelling are needed. Furthermore, the heating rate of the fire scenario is the dominant factor in deciding fire-resistance performance because it is a causal factor for spalling in HSC walls. And finally the reliability of wall's performance decreased sharply for HSC walls due to the expected spalling of the concrete and loss of cross-section integrity.Originality/valueLimited studies in the current open literature quantified the impact of constitutive models on the behaviour of RC walls. No studies have examined the effect of material models' uncertainty on wall’s response reliability under fire. Furthermore, the study's results contribute to the ongoing attempts to shape performance-based structural fire engineering.
The effect of supervisors making after-hours work requests on employees’ job stress: the cross-level contextual effect of social support
Authors: Kao Jui-Chung , Ma Hsiang-Yu , Rui-Hsin Kao , Cho Cheng-Chung 
Published: April 2024

PurposeThe rise of communication software has changed our work style. The objectives of this study are: (1) to explore the effect of supervisors making after-hours work requests using communication software (SWRUCS) on employees’ job stress, quality of life and (2) to examine the moderating effect of personality traits and the cross-level contextual effect of social support.Design/methodology/approachA questionnaire survey was conducted to obtain information from 357 employees.FindingsThe results suggested that SWRUCS exacerbated job stress, which negatively impacted on quality of life and well-being. Moreover, different personality traits can either increase or decrease the positive or negative effect of SWRUCS on job stress. This study also revealed that social support can reduce employees’ job stress in a cross-level fashion. Furthermore, social support, especially organizational and supervisory support, can decrease the negative effect of job stress on employees’ quality of life and well-being.Originality/valueTheoretically, this study has broadened the research scope of the organizational application of communication software, and practically, this study has demonstrated the reason why organizations should provide social support and select employees with suitable personality traits.
How aphids fly: Take‐off, free flight and implications for short and long distance migration
Authors: Bell James R. , Shephard Graham 
Published: April 2024

Abstract
An introduction to high‐speed photography and its entomological impact is provided, emphasizing the importance of high frame rates and high resolution.
The take‐off and free flight of Drepanosiphum platanoidis and Myzus persicae were studied in still air using high‐speed photography in HD.
The wing tip and body posture were tracked to show how they are displaced during each wingbeat cycle. The important structural elements of the wing are described.
The wingbeat is driven by a reinforced leading edge, the pterostigma and costa. The remainder of the coupled fore‐ and hindwing acts as a single aerofoil that deforms during flight, due to sparse venation and a lack of cross veins.
During flight, aphids use a ‘near clap and fling’ mechanism with a body pitch close to 90°. Rapid acceleration about the thoracic lateral axis into wing reversal generates enough lift for take‐off, typically within the first or second wingbeat.
Unique footage shows that aphids demonstrate a high degree of flight control and manoeuvrability in the lab, occasionally using forward and inverted flight, two flight modes that are otherwise poorly known.
While research into the impact of turbulent convection is needed, we posit that the strength of atmospheric forces presents a formidable challenge to aphid migrants. Above the flight boundary layer, migrating aphids may not easily oppose upwardly moving air, although if used, ‘frozen flight’ may cause them to descend on average.
We evaluate five devices for insect flight research.
A practical guide for the use of apalutamide for non‐metastatic castration‐resistant prostate cancer in Australia

Published: April 2024

AbstractStudies of patients with castrate‐resistant prostate cancer at high risk of developing overt metastases but with no current evidence of evaluable disease on computed tomography or bone scan non‐metastatic castrate‐resistant prostrate cancer have demonstrated increased metastasis‐free survival and overall survival following treatment with the next‐generation oral anti‐androgen apalutamide (in addition to therapies that aim to lower testosterone to castrate levels) or luteinizing hormone‐releasing hormone antagonist or surgical castration. Patients receiving apalutamide can be managed by medical oncologists, radiation oncologists, or urologists, preferably as part of a multidisciplinary team. However, the importance of additional safety monitoring for significant adverse effects and drug interactions should not be underestimated. The toxicities of apalutamide are manageable with experience and should be managed proactively to minimize their impact on patients. Monitoring of patients for apalutamide‐specific toxicities, including skin rash, hypothyroidism, and QT prolongation should be carried out regularly, particularly in the first few months following initiation. Monitoring should continue alongside monitoring for toxicities of androgen deprivation, including cardiovascular risk, hot flashes, weight gain, bone health, muscle wasting, and diabetic risk. This review is a practical guide to the use of apalutamide describing the management of patients including dosing and administration, toxicities, potential drug interactions, and safety monitoring requirements.
Paternal use of selective serotonin reuptake inhibitors and adverse health outcomes: A nationwide cohort study on 13,547 exposed children

Published: April 2024

AbstractBackgroundThe use of selective serotonin reuptake inhibitors (SSRIs) has increased over time. Several studies indicate that paternal use of medication may adversely affect the developing fetus. Only a few studies have investigated the association between preconceptional paternal exposure to SSRIs and the risks of adverse health outcomes in children.ObjectivesThis study aimed to assess adverse birth outcomes and adverse early life events in children fathered by men using SSRIs prior to conception.Materials and methodsAll live‐born singleton children born in Denmark from 1997 until 2019 and their parents were included. The exposed cohort comprised all children fathered by men using SSRIs 3 months prior to conception and the unexposed cohort comprised all other children. We estimated the odds ratios for adverse birth outcomes: small for gestational age (SGA), preterm birth, low Apgar score, and major congenital malformations. Furthermore, we estimated the hazard ratios for adverse early life events of infections and hospitalizations within 1 year from birth. We also examined adverse birth outcomes and the adverse early life events according to SSRI subgroups.ResultsThere was a statistically significantly increased odds ratio 1.15 (confidence interval, CI: 1.06–1.23) for preterm birth. No significant results were found for SGA, low Apgar score, and major congenital malformations. The adjusted hazard ratios for hospitalizations and infections were 1.06 (CI: 1.02–1.11) and 1.02 (CI: 0.97–1.07), respectively. There was a statistically significantly increased odds ratio for preterm birth with respect to the SSRI subgroups citalopram and escitalopram, and for hospitalizations with respect to citalopram.Discussion and conclusionAlthough the risks of certain adverse birth and adverse early life outcomes were statistically significantly increased, the ratios were small and may have limited clinical importance. Paternal use of SSRI was in general safe in the preconceptual period.
