Leaders' Machiavellian traits and servant leadership behaviors – A gender perspective
Authors: Xiu Lin , van Dierendonck Dirk , Lv Feng 
Published: August 2023

PurposeTwo studies are designed to address the research questions including an experimental study and a field study. The experimental study manipulated Servant Leadership (SL vs. non-SL), leaders' Machiavellianism (H-Mach vs L-Mach), and leaders' gender (male vs. female), and measured leadership effectiveness. The second study is a survey study that collected data from employees regarding their interaction with supervisors and their perceptions of supervisors' leadership behaviors.Design/methodology/approachLeadership behaviors can correspond to or deviate from leaders' personality traits. This study aims to study the interplay of two seemingly opposite constructs in leadership – a power-pursuing and manipulation-oriented trait (i.e. Machiavellianism) and an other-oriented leadership style (i.e. servant leadership behaviors) by examining whether the effect of servant leadership behaviors on perceived leadership effectiveness varies across high and low levels of Machiavellian traits. Furthermore, built upon gender role congruency theory, the researchers pay particular attention to the (leader) gender's role in the paradox of Machiavellian traits and servant leadership behaviors.FindingsResults from the two studies show that the relationship between servant leadership behaviors and followers' ratings of leaders' effectiveness varies with leaders' Machiavellian traits. More engagement in servant leadership behaviors serves as a remedy for high-Mach leaders to achieve leadership effectiveness, and this remedy effect tends to be greater for women leaders.Originality/valueTo the authors' best knowledge, this is one of the first attempts that examine the interplay of servant leadership behaviors and Machiavellianism on perceived leader effectiveness. The authors also contribute to the gender leadership literature by providing evidence for the contingencies of leaders' genders when employees evaluate leadership effectiveness with consideration for the dual demands for agency and communion from women leaders.
Health insurance coverage and maternal health services in Rwanda: a policy paradox
Authors: Malik Manzoor Ahmad , Alemu Wondimagegnehu 
Published: August 2023

PurposeResearch has found a strong correlation between maternal healthcare and health insurance coverage. But, despite having one of the best health coverage systems in the developing world, Rwanda still faces formidable challenges in provision certain key maternal health services, leading to higher levels of maternal morbidity and mortality. To understand this paradox, this study will examine the association between maternal health services and insurance coverage, utilizing the latest data from the Rwanda Demographic Health Survey.Design/methodology/approachUsing a sample of 6,167 childbearing women aged 15–49 years, a bivariate and multivariate analysis was conducted to examine the paradoxical relationship between health insurance and maternal health services, such as antenatal care, in Rwanda.FindingsThe results reveal significant differences in ANC4+ and the timing of the first ANC, which remain low in Rwanda. Despite significant improvements in delivery factors and skilled ANC providers, ANC4+ rates in the country remain the lowest. However, this study found a positive and significant association between ANC4+ and insurance coverage (AOR = 1.64, p < 0.001).Originality/valueRwanda has implemented an effective health insurance policy, but there has been minimal progress in the utilization of maternal health services. Therefore, there is a strong need for policy interventions to reduce barriers to healthcare utilization. Additionally, supply-side factors such as transportation, socio-cultural factors and other logistic barriers should be examined in greater detail. These factors may overshadow the impact of health insurance on the utilization of healthcare services in Rwanda.Peer reviewThe peer review history for this article is available at: https://publons.com/publon/10.1108/IJSE-01-2023-0059

Published: August 2023

Purpose
This paper aims to synthesize a novel series of monoazo disperse dyes based on N-(1-phthalimidyl)-naphthalimides by coupling with substitute anilines, naphthylamines and naphthol derivatives.

Design/methodology/approach
The purification of the intermediates and the dyes was carried out by recrystallization. The structures of the synthesized intermediates and the dyes were elucidated by spectroscopic techniques. The absorption maxima, molar extinction coefficient and halochromic properties of the dyes were determined spectrophotometrically using solvents of different polarity.

Findings
The dyes were applied on polyester using a high-temperature high-pressure dyeing machine, and the dyeing performance parameters such as colour build-up on fabrics, wash fastness, perspiration fastness and light fastness were evaluated. The colour build-up was found to be very good and the wash fastness (4–5) and perspiration fastness (4–5) were excellent, whereas the light fastness was found to vary from moderate to very good (3–6).

Research limitations/implications
It is not possible to investigate the structure of the synthesized dyes by nuclear magnetic resonance spectroscopic analysis due to the low solubility of dyes in deuterated solvents.

Originality/value
A novel method for the synthesis of a new category of monoazo disperse dyes based on N-(1-phthalimidyl)-naphthalimides was developed. These dyestuffs could be used in textile printing of polyester fabrics.
Mapping the structural properties of zinc scaffold fabricated via rapid tooling for bone tissue engineering applications
Authors: Kansal Abhishek , Dvivedi Akshay , Kumar Pradeep 
Published: August 2023

Purpose
The purpose of this study to investigate the organized porous network zinc (OPNZ) scaffolds. Their mechanical characteristics, surface roughness and fracture mechanism were assessed in relation to their structural properties. The prospects of fused deposition modeling (FDM) for printing metal scaffolds via rapid tooling have also been studied.

Design/methodology/approach
Zn scaffolds with different pore and strut sizes were manufactured via the rapid tooling method. This method is a multistep process that begins with the 3D printing of a polymer template. Later, a paraffin template was obtained from the prepared polymer template. Finally, this paraffin template was used to fabricate the Zn scaffold using microwave sintering. The characterization of prepared Zn samples involved structural characterization, microstructural study, surface roughness testing and compression testing. Moreover, based on the Gibson–Ashby model analysis, the model equations’ constant values were evaluated, which can help in predicting the mechanical properties of Zn scaffolds.

Findings
The scanning electron microscopy study confirmed that the fabricated sample pores were open and interconnected. The X-ray diffraction analysis revealed that the Zn scaffold contained hexagonal closed-packed Zn peaks related to the a-Zn phase, validating that scaffolds were free from contamination and impurity. The range for ultimate compressive strength, compressive modulus and plateau stresses for Zn samples were found to be 6.75–39 MPa, 0.14–3.51 GPa and 1.85–12.6 MPa by adjusting their porosity, which are comparable with the cancellous bones. The average roughness value for the Zn scaffolds was found to be 1.86 µm.

Originality/value
This research work can widen the scope for extrusion-based FDM printers for fabricating biocompatible and biodegradable metal Zn scaffolds. This study also revealed the effects of scaffold structural properties like porosity, pore and strut size effect on their mechanical characteristics in view of tissue engineering applications.
Research café: an informal learning space to promote research learning experiences of graduate students in a private university of Pakistan
Authors: Ahmad Sohail , Ansari Aisha Naz , Khawaja Saman , Bhutta Sadia Muzaffar 
Published: August 2023

Purpose
This paper aims to explore contribution of informal learning space - Research Cafe - to enrich research learning experiences of graduate students. Developing strong research skills among graduate students is a prime focus of higher education around the world. Thereby, universities are striving to maximise opportunities that can foster and enrich students’ learning experiences of research; however, the focus is mostly confined to formal opportunities such as research method courses and thesis writing. The provision of informal learning spaces has been recognised as a useful tool for fostering research learning experiences of graduates. This reflective paper is among a few focusing on a model of student-led informal learning space for enriching research experiences in higher education in the context of Pakistan.

Design/methodology/approach
This paper uses a reflective approach to generate a metalogue. The research experiences shared by the participants were further reflected by the authors after each research café session. The authors then shared their collective metacognitive reflections with each other, generating a metalogue, which was used as the data set. The metalogue was analysed thematically to generate themes.

Findings
Findings reveal that the research café is an informal space to promote academic socialisation by providing a conducive environment, peer support and informal supervision opportunities to foster the research learning experiences of graduate students. Importantly, the model presented in this paper provides a complimentary pathway for boosting learning experiences.

Research limitations/implications
This paper would be useful for graduate students, faculty and university manager to acknowledge the potential of informal learning spaces in promoting research learning experiences. This paper highlights opportunities for replication, and further empirical research are needed to establish the efficacy of research café.

Originality/value
This study contributes to the global debate about graduate research learning experiences through informal learning space, which is yet to be explored, particularly in developing contexts like Pakistan. The idea of the research café is original, as it was conceived keeping in consideration the contextual and cultural aspects. The methodology used in this paper was specifically derived which can be replicated by other researchers.

Authors: Habashi Youvalari Sajjad , Olianezhad Arash , Afrang Saeid 
Published: August 2023

Purpose
The purpose of this paper is to design and simulate a piezoelectric micropump using microelectromechanical systems technology for drug delivery applications.

Design/methodology/approach
Two piezoelectric actuators are used to actuate and bend the diaphragms in the proposed structure. In this micropump, the liquid flow is rectified by two silicon check valves.

Findings
The use of two piezoelectric transducer (PZT) actuators in the parallel mod not only reduces dead volume but also increases stroke volume as well. In addition to increasing the flow rate, this phenomenon enhances the operation of the micropump to have self-priming as smoothly as possible.

Originality/value
This actuating method results in a 22% increase in flow rate and compression ratio, as well as a 15% reduction in function voltage. The fluid-solid interaction is simulated using COMSOL Multiphysics 5.3a.
Strong above‐ground impacts of a non‐native ungulate do not cascade to impact below‐ground functioning in a boreal ecosystem
Authors: Swain Makayla , Leroux Shawn J. , Buchkowski Robert 
Published: August 2023

AbstractExperimental studies across biomes demonstrate that herbivores can have significant effects on ecosystem functioning. Herbivore effects, however, can be highly variable with studies demonstrating positive, neutral or negative relationships between herbivore presence and different components of ecosystems. Mixed effects are especially likely in the soil, where herbivore effects are largely indirect mediated through effects on plants.We conducted a long‐term experiment to disentangle the effects of non‐native moose in boreal forests on plant communities, nutrient cycling, soil composition and soil organism communities.To explore the effect of moose on soils, we conduct separate analyses on the soil organic and mineral horizons. Our data come from 11 paired exclosure‐control plots in eastern and central Newfoundland, Canada that provide insight into 22–25 years of moose herbivory. We fit piecewise structural equations models (SEM) to data for the organic and mineral soil horizons to test different pathways linking moose to above‐ground and below‐ground functioning.The SEMs revealed that moose exclusion had direct positive impacts on adult tree count and an indirect negative impact on shrub percent cover mediated by adult tree count. We detected no significant impact of moose on soil microbial C:N ratio or net nitrogen mineralization in the organic or mineral soil horizon. Soil temperature and moisture, however, was more than twice as variable in the presence (i.e. control) than absence (i.e. exclosure) of moose. Overall, we observed clear impacts of moose on above‐ground forest components with limited indirect effects below‐ground. Even after 22–25 years of exclusion, we did not find any evidence of moose impacts on soil microbial C:N ratio and net nitrogen mineralization.Our long‐term study and mechanistic path analysis demonstrates that soils can be resilient to ungulate herbivore effects despite evidence of strong effects above‐ground. Long‐term studies and analyses such as this one are relatively rare yet critical for reconciling some of the context‐dependency observed across studies of ungulates effects on ecosystem functions. Such studies may be particularly valuable in ecosystems with short growing seasons such as the boreal forest.

Published: August 2023

AbstractObjective(s)To understand Australian health professionals' perceptions of their knowledge and previous training about frailty, as well as barriers to frailty assessment and management in their practice.MethodsA cross‐sectional online survey was developed and distributed to health professionals (medical, nursing and allied health) engaged in clinical practice in Australia through convenience and snowball sampling techniques from March to May 2022. The survey consisted of five sections: frailty training and knowledge; confidence in recognising and managing adults with frailty; the importance and relevance of frailty; barriers to assessing and managing frailty in practice; and interest in further frailty training. Responses were analysed using descriptive statistics.ResultsThe survey was taken by 736 health professionals. Less than half of respondents (44%, 321/733) reported receiving any training on frailty, with 14% (105/733) receiving training specifically focussed on frailty. Most respondents (78%, 556/712) reported ‘good’ or ‘fair’ understanding of frailty. The majority (64%, 448/694) reported being ‘fairly’ or ‘somewhat’ confident with identifying frailty. Almost all respondents (>90%) recognised frailty as having an important impact on outcomes and believed that there are beneficial interventions for frailty. Commonly reported barriers to frailty assessment in practice included ‘lack of defined protocol for managing frailty’ and ‘lack of consensus about which frailty assessment tool to use’. Most respondents (88%, 521/595) were interested in receiving further education on frailty, with a high preference for online training.ConclusionsThe findings suggest frailty is important to health professionals in Australia, and there is a need for and interest in further frailty education.
Disease‐modifying therapies in multiple sclerosis: A focused review of rituximab
Authors: Alping Peter 
Published: August 2023

AbstractBackgroundTreatment for multiple sclerosis (MS), a chronic inflammatory disease of the central nervous system, has changed drastically in the last 30 years. Several different disease‐modifying therapies are now available, with off‐label use of the B‐cell‐depleting antibody rituximab becoming an increasingly popular choice, as more and more studies report on its effectiveness.ObjectivesThe objective of this study was to summarize the current state of evidence for rituximab as a treatment for relapsing‐remitting MS (RRMS).MethodsA structured literature search was conducted in PubMed, focusing on peer‐reviewed studies of adult populations with RRMS. Ongoing trials with rituximab in MS were identified through Clinicaltrials.gov and additional references were identified through review articles.FindingsDespite promising results for rituximab as a treatment of MS, the market‐authorization holder switched focus from rituximab and discontinued the industry‐sponsored trials programme. However, several observational studies, smaller clinical trials and one large investigator‐initiated randomized‐controlled trial have continued to report fewer clinical relapses, fewer contrast‐enhancing lesions on magnetic resonance imaging and better drug survival with rituximab, compared with MS‐approved alternatives.ConclusionsRituximab should be considered as both a first‐ and second‐line therapy option for most MS patients with active, non‐progressive disease. However, as an off‐label therapy for MS, regulatory approval remains a barrier for wider adoption in many countries.
