Authors: Mwesigwa Rogers , Alupo Sarah , Nakate Mariam , Mayengo Joseph , Nabwami Ruth 
Published: September 2024

PurposeThis study aims to examine the association between institutional support dimensions and female business sustainability in Uganda.Design/methodology/approachThis study adopted a cross-sectional and quantitative approach. We collected data from a sample of 224 female-owned businesses using a self-administered questionnaire.FindingsThe findings indicate that institutional support is positively and significantly associated with the sustainability of female-owned businesses. The findings further indicate that all dimensions of institutional support (financial support, government policies and programs) are significantly and positively associated with female business sustainability.Research limitations/implicationsThis study employed a cross-sectional design; thus, it was impossible to monitor changes in the behavior of female-owned businesses over time. It may be possible to generalize the findings of this study to other developing countries.Originality/valueThis study provides initial empirical evidence on the relationship between institutional support dimensions and female business sustainability using evidence from a developing African economy – Uganda.
Public value and public sector accountability in New Zealand
Authors: Sharma Umesh , Kaur Amanpreet 
Published: September 2024

PurposeThis paper aims to present an overview of the development of the public value accounting approach and its application to public sector accountability in New Zealand.Design/methodology/approachThe study uses the public value framework to demonstrate the outcome-related planning and control mechanisms that are put in place in the public sector. The paper draws from archival research using a case study of the Ministry of Pacific Peoples.FindingsThe public value accounting-based calculative practices are on the rise within the New Zealand public sector. New Zealand’s public sector is oriented towards a public value budget.Research limitations/implicationsThe study is limited through the use of secondary data and the use of content analysis methodology. The research enables policymakers to fund initiatives that enhance the well-being of the community. Public value can be created as a joint effort between citizens and government as evident from the case study. By looking at the totality of the impact of government through public value creation can help to improve policy decisions. Government policymakers need to emphasise on those public value creation that has an enormous positive impact on the citizens. This will also help to improve the relationship between government and citizens through increased trust in the government by citizens.Originality/valueThe paper contributes to the public value research which has received relatively less attention in the literature. Public value accounting is a research field that is yet to achieve a significant level of attention.
Understanding how pre-service teachers design numeracy-rich activities in non-mathematic curriculum areas
Authors: Getenet Seyum 
Published: September 2024

PurposeThis study investigates the knowledge gaps of primary pre-service teachers (PSTs) in designing numeracy-rich tasks (NRTs) that incorporate real-life contexts across non-mathematics curriculum areas. It aims to understand the PSTs' competencies and the specific areas where they require further professional development.Design/methodology/approachThe study involved 100 final-year PSTs from a primary education degree programme. These PSTs designed NRTs as part of a course focused on integrating numeracy across the curriculum. Data were collected from these assignments and analysed using a three-point analytical scoring scale and a knowledge framework to evaluate the presence of essential knowledge types in the designs.FindingsThe analysis revealed that while PSTs were adept at creating engaging activities focusing on teaching numeracy concepts, they struggled to effectively use numeracy to teach concepts in non-mathematics curricula. Most PSTs emphasised curriculum areas like Science and Geography in their NRTs. Significant gaps were noted in their ability to select suitable materials and in their understanding of integrating mathematics as a vehicle for teaching other subjects.Originality/valueThis study provides a unique insight into the challenges faced by PSTs in effectively integrating numeracy in non-mathematics curriculum areas. By identifying these knowledge gaps, the study contributes to enhancing the design of teacher education programmes, ensuring PSTs are better equipped to deliver comprehensive educational experiences.
Do participants lie? Imposter participants in online qualitative research
Authors: Wang Yixuan 
Published: September 2024

PurposeThe wide adoption of online methodologies has enabled methodological innovations in online qualitative research. However, it also increases the risk of imposter participants who may falsify or fabricate their identities, particularly in studies that offer incentives/compensation. Imposter participants pose a significant threat to data and research integrity. This paper draws on the author’s experience of making methodological adjustments after encountering imposter participants in an online qualitative study to highlight the significance of taking proactive actions throughout online qualitative studies to address this concern.Design/methodology/approachThe paper provides a review of how qualitative scholars approach this issue in online participant recruitment, data collection and data analysis. Then, the author shares methodological changes made for ongoing recruitment and data collection, as well as handling data collected from imposter participants.FindingsSignificant differences exist between verified participants and the incidences of imposter participants. Strategies in participant eligibility check, interview and member checking can be effective ways to address imposter participants throughout research projects.Originality/valueThe discussion on this concern is scant in the qualitative research community and so is the discussion of methodological and ethical approaches to address this issue. This paper underscores the importance for researchers to be aware of the risk of imposter participants and offer methodological considerations across stages in online qualitative studies for ethical and proactive methodological actions.
Differentially private survey research
Authors: Evans Georgina , King Gary , Smith Adam D. , Thakurta Abhradeep 
Published: September 2024

AbstractSurvey researchers have long protected respondent privacy via de‐identification (removing names and other directly identifying information) before sharing data. Unfortunately, recent research demonstrates that these procedures fail to protect respondents from intentional re‐identification attacks, a problem that threatens to undermine vast survey enterprises in academia, government, and industry. This is especially a problem in political science because political beliefs are not merely the subject of our scholarship; they represent some of the most important information respondents want to keep private. We confirm the problem in practice by re‐identifying individuals from a survey about a controversial referendum declaring life beginning at conception. We build on the concept of “differential privacy” to offer new data‐sharing procedures with mathematical guarantees for protecting respondent privacy and statistical validity guarantees for social scientists analyzing differentially private data. The cost of these procedures is larger standard errors, which can be overcome with larger sample sizes.
Losing on the home front? Battlefield casualties, media, and public support for foreign interventions
Authors: Fetzer Thiemo , Souza Pedro C. L. , Vanden Eynde Oliver , Wright Austin L. 
Published: September 2024

AbstractHow domestic constituents respond to signals of weakness in foreign wars remains an important question in international relations. This paper studies the impact of battlefield casualties and media coverage on public demand for war termination. To identify the effect of troop fatalities, we leverage the timing of survey collection across respondents from nine members of the International Security Assistance Force in Afghanistan. Quasi‐experimental evidence demonstrates that battlefield casualties increase the news coverage of Afghanistan and the public demand for withdrawal. Evidence from a survey experiment replicates the main results. To shed light on the media mechanism, we leverage a news pressure design and find that major sporting matches occurring around the time of battlefield casualties drive down subsequent coverage, and significantly weaken the effect of casualties on support for war termination. These results highlight the role that media play in shaping public support for foreign military interventions.

AbstractAimTo compare trajectories of social functioning in peer problems and prosocial behavior from 5 to 13 years between individuals born very preterm (VPT) and full‐term (FT).MethodsParticipants were from the Victorian Infant Brain Study (VIBeS) longitudinal cohort, consisting of 224 individuals born VPT and 77 born FT recruited at birth. Social functioning was measured using the parent‐rated Strengths and Difficulties Questionnaire (SDQ) peer problems and prosocial behavior subscales at 5, 7, and 13 years' corrected age. Multilevel mixed effects models were fitted.ResultsPeer problems increased with age (adjusted mean difference per year = 0.04, 95% confidence interval [CI] = 0.01, 0.07, p = 0.02), with higher peer problems in the VPT compared with the FT group (adjusted mean difference between groups = 0.46, 95% CI = 0.06, 0.86, p = 0.02). Prosocial behavior increased from early to middle childhood and decreased approaching adolescence, but was similar between VPT and FT groups (adjusted mean difference between groups = −0.05, 95% CI = −0.50, 0.40, p = 0.82).ConclusionChildren born VPT are at greater risk for peer problems than FT peers and may benefit from receiving greater early social support.
Vaccine hesitancy as indecision: Creation and evaluation of the Unidimensional Vaccine Hesitancy Scale
Authors: Howard Matt C. 
Published: September 2024

AbstractBackgroundSeveral authors have argued that vaccine hesitancy should be conceptualized as indecision in the vaccination decision‐making process, but no established measure with support for its psychometric properties and validity has been created from this operational definition.AimsTo resolve this tension, this article undergoes a four‐study scale development process to create the 4‐item Unidimensional Vaccine Hesitancy Scale (UVHS).Materials and MethodsWe conduct four survey studies utilizing a total sample size of 884.ResultsIn Studies 1 (n = 297) and 2 (n = 298), we provide psychometric support for the measure via exploratory and confirmatory factor analysis. In Studies 3 (n = 193) and 4 (n = 106), we support the concurrent and discriminant validity of the measure by assessing its relations with relevant constructs, such as vaccination readiness and acceptance, and we also provide initial indicators of the scale's possible predictive qualities by testing its time‐separated effects with vaccination willingness, receipt and word‐of‐mouth.DiscussionWe leverage these results to provide a number of theoretical insights and suggestions for future practice. Of note, we highlight that different conceptualizations and operationalizations for the same construct can produce notably differing empirical findings, and vaccine hesitancy is no different.ConclusionOur cumulative efforts indicate that the UVHS is an appropriate measure to assess vaccine hesitancy as indecision.

Abstract

One of the major threats to biodiversity is changing fire regimes, particularly increasingly frequent fires, especially during the dry season. However, studies on the direct and indirect effects of fire on biotic responses in aquatic ecosystems are still scarce. In this study, we investigated how water quality and phytoplankton community structure were affected by different ash concentrations from burning vegetation of a tropical savanna.

We used a microcosm experiment to simulate the aquatic ecosystem with different ash concentration scenarios and evaluated the water quality and the composition, richness and density of phytoplankton over time.

We found increased total phosphorus and ammoniacal nitrogen concentrations after ash addition, in addition to changes in electrical conductivity. We identified 242 phytoplankton taxa throughout the experiment and identified changes in species composition among treatments. We identified changes in the taxonomic richness of total phytoplankton, green algae and desmids over time. The density of total phytoplankton, diatoms, green algae, desmids and cyanobacteria also changed over time.

Our results suggest that ash from terrestrial fires affects water quality and phytoplankton communities depending on the proportion of ash input. Our results serve as a basis for further investigations of the effects of fire on abiotic conditions in aquatic ecosystems and their communities over long periods of time. Finally, longer‐term experiments are needed to evaluate delayed responses by the phytoplankton community.

AimsThe PEComa family of tumours is defined by spindle/epithelioid cells with myomelanocytic differentiation. A small subset harbours TFE3 fusion; however, YAP1::TEE3 has not been reported. Clear cell stromal tumour of the lung (CCST‐L) is an emerging entity characterized by spindle to epithelioid cells with focal cytoplasmic clearing, inflammatory infiltrates, no myomelanocytic differentiation, and YAP1::TFE3 fusion. Herein, we report two cases of lung tumours with myomelanocytic differentiation that showed inflammatory spindle cell histology, focal epithelioid clear cells, as well as YAP1::TFE3 fusion.Methods and ResultsThe patients were both men, aged 61 and 68 years. The tumours in both cases presented as well‐circumscribed solid masses involving the lung hilum. After lobectomy, no recurrence was observed at 7 and 32 months. Both tumours shared storiform to short fascicular growth of long spindle cells, with a minor component of epithelioid cells showing clear cytoplasm in the background of substantial intratumoral chronic inflammation and dilated blood vessels. One tumour showed focal melanin deposition. Both tumours were immunohistochemically positive for HMB45, Melan A, and h‐caldesmon. Fluorescence in situ hybridization assays indicated the presence of YAP1::TFE3 fusions, which was confirmed by RNA sequencing in one case tested, and by immunohistochemical TFE3 expression and loss of YAP1 C‐terminus staining.ConclusionWe present two cases of inflammatory spindle to epithelioid cell tumours of the lungs with myomelanocytic differentiation and YAP1::TFE3 fusion. This unique morphology and gene fusion suggest that these tumours may constitute a distinct subset of lung PEComa. Furthermore, morphological and molecular overlap with CCST‐L gives rise to a hypothesis of a potential inherent relationship between PEComa and CCST‐L.

Published: September 2024

AbstractIn this work, the Yb2Si2O7 interphase was prepared on SiC fibers using the sol–gel method. The influence of sol concentration on the morphology of the interphase was discussed. After heat treatment in argon at 1200°C for 1 h, the Yb2Si2O7 was grown in situ on the fiber surface, forming an interphase layer. Then, SiCf/Yb2Si2O7/SiC minicomposites were prepared by chemical vapor infiltration (CVI). The Yb2Si2O7 interphase exhibited no changes throughout the high‐temperature preparation process and maintained stability and compatibility with the fiber and matrix. The tensile strength of SiCf/Yb2Si2O7/SiC minicomposites with Yb2Si2O7 interphase was significantly higher than SiCf/SiC minicomposites without interphase. The crack deflection, interfacial debonding, and fiber pullout were observed in the tensile fracture of the SiCf/Yb2Si2O7/SiC minicomposites.
Stabilization of thermal storage ceramics via the phase reconstruction of ferrotitanium slag and migration of Mg element

Published: September 2024

AbstractIn this study, aluminum titanate/anorthite (Al2TiO5‐CaAl2Si2O8) ceramics were fabricated from ferrotitanium slag through phase reconstruction. Stabilization of the ceramic was achieved by migration of Mg element into Al2TiO5 phase. The results indicated that optimal performance was achieved with the addition of 4 wt% MgO and 60 wt% ferrotitanium slag at 1370°C. The ceramic exhibited bulk density of 3.11 ± 0.01 g/cm3, thermal storage density of 1.51 kJ/cm3, and thermal expansion coefficient of 3.40 × 10−6/°C (1000°C), respectively. Additionally, the solid solution of Mg2+ in the Al2TiO5 lattice reduced the formation of microcracks and enhanced the mass transfer process. Consequently, the sintering temperature decreased from 1415°C to 1370°C while the bending strength increased from 61.25 ± 1.05 MPa to 75.92 ± 7.72 MPa. Furthermore, finite element simulation demonstrated that higher thermal expansion led to concentrated thermal stress, potentially increasing the possibility of ceramic cracking. This research provides a new strategy for preparing low thermal expansion ceramics from titanium‐containing solid waste.

Published: September 2024

AbstractRare‐earth hafnates are gaining attention due to their excellent high‐temperature phase stability and low thermal conductivity. However, they still have shortcomings of low thermal expansion and poor calcium‐magnesium‐aluminum‐silicate (CMAS) corrosion resistance. In this study, we employed high‐entropy engineering and component design to synthesize three high‐entropy hafnates (La0.2Ce0.2Nd0.2Gd0.2T0.2)2Hf2O7 (T = Dy, Ho, Tm) as well as a single‐component hafnate Nd2Hf2O7, with the aim of preparing thermal barrier coatings with an excellent comprehensive performance. Test results indicate that the high‐entropy compositions have excellent thermal properties. The focus is on elucidating the corrosion process and failure mechanism of CMAS at 1300°C. Moreover, the analysis of residual CMAS and corrosion products was conducted to evaluate the discrepancies in CMAS corrosion behavior among the various compositions.

Published: September 2024

Abstractn‐type Dy‐doped Ca2MnO4 powders with the Ruddlesden–Popper structure were synthesized by the combustion method and sintered by conventional sintering and spark plasma sintering (SPS). Conventional sintering fails to densify Ca2MnO4, but the addition of Li2O proves to be a highly effective sintering additive, albeit with a detrimental impact on electrical conductivity. In contrast, SPS at 850°C for 1 min yields nanostructured, nearly fully dense samples, demonstrating superior outcomes. The dimensionless figure of merit ZT reaches 0.02 at 750°C. Additionally, the best sample exhibits a remarkable hardness value of 10.7 GPa, underlining the excellent mechanical properties achieved through this innovative approach.

Abstract0.92(K0.5Na0.5)NbO3‐0.02(Bi0.8Li0.2)TiO3‐0.06BaZrO3 (BZ6) is a lead‐free piezoelectric ceramic with excellent piezoelectric performance (such as the normalized strain reaches up to 476 pm/V). Considering potential device applications, it is essential to evaluate the ceramic's resistance to electrical fatigue. The bipolar fatigue behavior of (K,Na)NbO3 (KNN)‐based lead‐free piezoelectric ceramics was investigated. Comparative analysis shows that BaZrO3‐modified KNN ceramics have strong resistance to bipolar fatigue due to the coexistence of rhombohedral and tetragonal phase and the depinning of domain walls, whereas microstructural damage under mechanical stress makes pristine KNN ceramics susceptible to bipolar cycling. The hypothesis was systematically verified through the study of cycle‐dependent small and large signal parameters and microscopic morphology. Our findings can guide the future design of KNN compositions with high resistance to bipolar fatigue.
