Mumpreneurs’ decision-making when facing uncertainty and competing goals
Authors: Ameen Nisreen , Hoelscher Vera , Hughes Mathew 
Published: December 2024

PurposeThis study examines the decision-making processes and coping mechanisms of mumpreneurs (entrepreneurs who are mothers) as they navigate complex environments characterized by uncertainty and competing goals that are heightened by their circumstances and marginalization.Design/methodology/approachIn-depth interviews were conducted with 26 female entrepreneurs in the United Kingdom who are raising young children.FindingsThe research develops a new framework based on regulatory focus theory. It uncovers multiple layers of uncertainty facing mumpreneurs, including traditional business-focused uncertainties such as global crises, market volatility and financial risks, but including uncertainties derived from the challenge of balancing business growth with family responsibilities. Despite these complexities, mumpreneurs pursue multiple competing goals related to their businesses, families and societal contributions. The study identifies four key coping and decision-making mechanisms employed by mumpreneurs in complex environments: intuition, adaptability, confidence and a dynamic interplay between promotion and prevention regulatory focus.Originality/valueThis study contributes to entrepreneurship literature by providing a nuanced understanding of how mumpreneurs are required to navigate uncertainty and competing demands and the key coping and decision-making mechanisms they use to achieve this. It challenges the binary view of regulatory focus theory and offers insights into the unique stress dynamics experienced by mother entrepreneurs. The findings underscore the need for tailored support systems, including coaching and mentoring programs for mumpreneurs with young children. Moreover, the research highlights the importance of policy interventions, such as increased childcare subsidies, to support parental entrepreneurship and advance gender equality goals.

Published: December 2024

PurposeThis study investigates the nexus of top management commitment and institutional pressures towards enhancing sustainable energy consumption in African Higher Institutions of Learning.Design/methodology/approachUsing a structured questionnaire survey, cross-sectional data collected from 64 higher institutions of learning registered with the Uganda National Council for Higher Education were analyzed using the Statistical Package for Social Sciences (SPSS).FindingsThe findings revealed that top management commitment and institutional pressures individually associate with sustainable energy consumption. Top management commitment does not cause variations in sustainable energy consumption. However, when top management commitment coalesces with institutional pressures, they significantly predict sustainable energy consumption.Research limitations/implicationsThe current study focuses on Higher Institutions of Learning in Uganda. Hence caution should be taken before generalization of findings. This study therefore sets ground for future studies to investigate sustainable energy consumption in other institutions.Originality/valueThis study tests the efficacy of top management commitment and institutional pressures on sustainable energy consumption using evidence from African Higher Institutions of Learning. It provides new directions for study in such a nascent area of critical national dimension as sustainability and climate change issues top the global agenda.
Circular economy, methane capture, and climate education in US HEIs
Authors: Mullis Charles S. , Finley-Brook Mary 
Published: December 2024

Purpose
This study aims to analyze the involvement of US colleges and universities in methane capture projects in the waste sector and their related educational initiatives aiming to build circular economies and reduce greenhouse gas (GHG) emissions.

Design/methodology/approach
The authors compiled a subset of 22 “early adopting” institutions – those that received media attention for solid or liquid waste methane capture projects from 1999 to the present. The authors included all cases found within a reasonable number of queries. The institutions fell into two groups: (1) schools directly involved in gas capture projects, and (2) schools that purchased third-party offsets tied to landfill gas (LFG) projects. The authors assessed transparency and accountability, which the authors determined as fundamental to GHG mitigation and climate education. The authors expanded on five innovative cases from our subset to illustrate pathways to improve equity and circularity in waste flows.

Findings
US higher education institutions (HEIs) can measure and educate more transparently about waste streams. While institutions using LFG offsets range in size, curriculum and geography, there were few methane capture projects supplying energy directly to campuses. Although HEIs generally rely on third-party providers for waste management, cases demonstrate how universities can play a role in methane use, and be incubators for climate action and related employment.

Practical implications
Illustrative cases demonstrate the educational and institutional benefits from methane use.

Social implications
HEIs can generate pathways of a “just” transition to a fossil-free circular economy.

Originality/value
To the best of the authors’ knowledge, this is one of the first comparative studies examining waste sector methane capture and the potential for high-impact educational practices and sustainability training in US HEIs.
Post-Implementation challenges of the Outcome-Based budgeting model in budgetary practices: a Malaysian perspective
Authors: Mohd Gharib Nurul Shuhada , Isa Che Ruhana , Saleh Zakiah 
Published: December 2024

Purpose
This study aims to explore the challenges in post-implementing the Outcome-Based Budgeting (OBB) model in budgetary practices in Malaysian Government agencies, in the context of government official’s perspective.

Design/methodology/approach
A qualitative methodology by collecting data from eight budget experts within federal government agencies through semi-structured interviews was used. Purposive sampling was used to select informants based on their relevant experiences and roles in the OBB model and associated budgetary processes. Data analysis involved thematic analysis using ATLAS.ti software, with member checking to enhance credibility.

Findings
Sustainability, innovation characteristics, organisational dynamics, individual capabilities and social context are identified as critical factors influencing the successful post-implementation of the OBB model in Malaysian federal government agencies. Organisational dynamics, encompassing policy control and Budget Review Officers role, as well as social factors, such as the presence of an OBB champion and broader buy-in, significantly impact the model’s effectiveness. These findings underscore the complex interplay of factors shaping the post-implementation phase of OBB in the Malaysian budgetary context.

Research limitations/implications
This study is constrained by its qualitative methodology and focus on the Federal Government of Malaysia, limiting the generalisability of findings. Future research using quantitative or mixed methods, expanded to include other government entities and comparative analysis across government levels is recommended to enhance understanding of OBB implementation challenges.

Practical implications
This research contributes to the existing body of knowledge on Performance-based budgeting (PBB) implementation, particularly in developing countries. By identifying critical success factors and barriers, it offers valuable insights for policymakers and practitioners seeking to improve public financial management. The study’s focus on Malaysia’s OBB experience provides timely and relevant information for addressing challenges in budgetary practices. Additionally, the research offers practical guidance for organisations navigating change management and building capacity for PBB implementation.

Originality/value
The study’s originality lies in its focus on the post-implementation challenges of the OBB within Malaysian Government agencies, which are largely under-studied. By using the Diffusion of Innovation theory, the study systematically investigates the interplay of sustainability, innovation characteristics, organisational dynamics, individual capabilities and social context in shaping OBB outcomes. Identifying sustainability and organisational dynamics as critical success factors contributes to the ongoing discourse on public sector budgeting reforms, particularly in developing country contexts.
Data-driven monitoring of powder build-up for condition-based maintenance in semiconductor manufacturing facility
Authors: Kim Chanyoung , Sim Hye Eun , Hong Sang Jeen 
Published: December 2024

PurposeSemiconductor fabrication facilities often suffer from undesired particle introduction into process chambers in vacuum systems. Ideally, it is unusual to observe particles formed in the exhaust pumping line inside the chamber, but non-volatile compound products at relatively low temperatures jeopardize the vacuum pumping system, gas scrubber and the wafer-in-process. This study proposes a monitoring system for constructing a complete condition-based maintenance system for diagnosing the powder build-up within exhaust pipes used in the semiconductor manufacturing industry. This system includes ultrasonic sensors and machine learning.Design/methodology/approachEmploying ultrasonic sensors, physical and data-driven models are established. The time- or frequency-domain data acquired by the monitoring system are converted into cepstrums for modeling the powder layer thickness using machine learning.FindingsThe algorithms used in the proposed system successfully classified the thicknesses with an average accuracy of above 97%, and feature importance analysis identified the quefrency that varied with the thickness of the powder layer.Practical implicationsThe limitation of this research lies within the lab environment. It is unfortunate that the suggested method has not been evaluated in actual semiconductor manufacturing facilities, as powder build-up may take more than a few months to be called the facility maintenance. However, the submitted paper is still valid in academic and engineering aspects to be utilized in industry.Originality/valueWe modeled the system using data acquired by an ultrasonic sensor, and we constructed a data-driven model that was trained using cepstral data to replace the physical models that monitor thickness. We are the first to use ultrasound and machine learning to estimate the thickness of powder in the exhaust vacuum pumping line.
Feed-in tariffs in scaling up solar and wind energy to shield nations from fossil fuel dependence
Authors: Jose Anu K , Patra Biswajit 
Published: December 2024

PurposeThe study attempts to understand how feed-in-tariffs (FITs), government expenditures and environmental quality can impact solar and wind energy consumption (SWC) of nations and can act as a shield against global energy tensions by reducing fossil fuel dependence.Design/methodology/approachOrganization for Economic Co-operation and Development (OECD) and non-OECD countries are compared based on the effectiveness of total governmental expenditures, mean FITs and carbon emissions in influencing SWC and fossil fuel dependence over the period 2000–2019. Fixed-effects panel data regression and bootstrapped panel quantile regression are used in estimations.FindingsFITs and government expenditures boosted SWC in OECD countries, while they were not very effective in non-OECD. Unlike OECD nations, total government expenditures were also not influential in reducing fossil fuel dependence in non-OECD countries. Countries with higher carbon emissions had lower SWC and higher fossil fuel dependence, showing lesser environmental concerns and energy crisis vulnerabilities.Research limitations/implicationsThere is a need for more renewable energy financing programs and governmental expenditures to promote SWC in non-OECD nations. The detrimental effect of carbon emissions on SWC and the positive effect on fossil fuel dependence show the lack of efforts in high carbon-emitting countries in adopting cleaner technologies.Originality/valueThe unique contribution of the study lies in the comparative analysis of the effectiveness of renewable energy financing for country groups and exploring the effects on renewables and fossil fuels simultaneously. An analysis of higher carbon emissions leading to an emission loop by increasing fossil fuel dependence also provides novelty to the study.
Invasive Amaranthus retroflexus obtains a competitive advantage over native A. tricolor under the addition of A. retroflexus leaf litter

Published: December 2024

AbstractThere is a scarcity of research examining the influences of the addition of leaf litter from invasive plants on their own growth performance, particularly in the context of their own competitive advantage when co‐cultured with native plants. This study aimed to examine the influences of the addition of a gradient of the invasive plant Amaranthus retroflexus L. leaf litter (ARLL) on its competitive advantage. An indoor planting experiment was conducted to analyze the competitive advantage of A. retroflexus with three forms of incubation conditions, that is, A. retroflexus in the monoculture, A. tricolor L. in the monoculture, and A. retroflexus co‐cultured with A. tricolor. The addition of a low amount of ARLL was found to significantly enhance the competitive ability to obtain sunlight of both Amaranthus plants. The leaf photosynthetic capacity of A. tricolor and the growth competitiveness of A. retroflexus were found to be greater in the co‐culture than in the monoculture. The competitive ability to obtain sunlight, the relative competitive intensity, and relative dominance of A. retroflexus were found to be stronger than those of A. tricolor regardless of the amount of ARLL and the form of incubation condition. Consequently, A. retroflexus can obtain a competitive advantage over A. tricolor under the addition of a gradient of ARLL. Accordingly, the stronger competitive advantage of A. retroflexus may facilitate its invasion process.

Pino's Pizza: An Instructional Case*
Authors: Kenno Staci A. , Sainty Barbara J. , Mancini Daniel 
Published: December 2024

AbstractThis case asks students to prepare a report addressing a number of strategic and operational issues at Pino's Pizza, a small chain of pizzerias in the Niagara Region of Ontario. Pino's son, Mario, is taking over the business and has several new ideas that he wants to explore. He has asked for help in assessing various expansion opportunities, introducing new products, changing the current delivery method, and developing a better information system. Students must obtain an understanding of Pino's current vision and mission, strategic position, and financial situation before analyzing the strategic fit and quantitative and qualitative implications of the alternatives under consideration. These strategic alternatives include franchising the Pino's Pizza name, opening a new sit‐down restaurant, and entering into a new partnership with a local winery. Mario is also considering offering gluten‐free pizza, outsourcing pizza delivery, and designing a new computer system to ensure adequate controls. The case will enable students to integrate a number of issues faced by a small business seeking growth through evaluating strategic and operational issues and providing supported recommendations.
Defying decline: Very low chytrid prevalence in tadpoles, yet high infection in adults in a naturally recovering frog species
Authors: Crawford‐Ash J. , Erens J. , Martel A. , Noble D.W.A. , Pasmans F. , Scheele B.C. 
Published: December 2024

AbstractAmphibian chytrid fungus, Batrachochytrium dendrobatidis (Bd), is associated with declines in ~500 amphibian species globally. Decades after initial disease outbreaks, the trajectory of impacted species varies substantially; while some species continue to decline, there are instances of natural recovery, such as the whistling tree frog, Litoria verreauxii, in south‐eastern Australia. The decline and subsequent recovery of this species have been quantified through repeated surveys of historically occupied sites over the past 30 years; however, the underlying mechanisms driving this recovery remain unknown. In this study, we investigate the potential factors facilitating the recovery of L. verreauxii by examining Bd prevalence and intensity in both adults and tadpoles. Specifically, we addressed the following hypotheses: (1) Bd prevalence in tadpoles would be lower compared to adults at the same breeding sites, (2) Bd prevalence in tadpoles would decrease over the spring breeding season due to the increasing availability of warm water microhabitats where tadpoles could potentially avoid or clear Bd infections and (3) there would be a negative correlation between Bd prevalence in tadpoles and the abundance and diversity of microfauna, which may consume Bd zoospores. Our findings indicate that tadpole infection prevalence remained consistently low at 1.36% (95% CI: 0.6–2.47%) throughout our spring sampling period, across different developmental stages. Adults had moderate to high prevalence within the same ponds at 50.53% (95% CI: 43.19–57.84%). No effect of temperature or microfauna diversity and abundance was apparent. While the mechanisms driving the recovery of this species remain unknown, low infection prevalence in tadpoles is likely a key component to the species' recovery. Our results emphasize the need for comprehensive investigations in Bd dynamics across all life history stages within recovering and declining amphibian species.

Published: December 2024

BackgroundAssisted reproductive technology (ART) pregnancies are at greater risk of birth defects than non‐ART pregnancies. Teratogenic medication exposure is a potential cause of birth defects that has not been compared between ART and non‐ART pregnancies.AimsTo determine whether the prevalence of exposure to teratogenic medicines during pregnancy varies by conception method (ART and three non‐ART groups: ovulation induction (OI), subfertile untreated, and fertile naturally conceiving).Materials and MethodsWe linked state and commonwealth datasets for all live and stillbirths (≥20 weeks) in Western Australia with a conception date ≥1 July 2012 and date of birth ≤31 December 2014. We calculated the prevalence of exposure to teratogenic medicines (Therapeutic Goods Association Category D/X) across conception groups for the: (i) first trimester, and (ii) second and third trimesters.ResultsWe identified 2041 ART, 590 OI, 2063 subfertile and 52 987 fertile pregnancies (57 681). The overall prevalence of exposure to Category D/X medicines was 0.8% in the first trimester, and 0.7% in the second and third trimesters. Category X medicines exposure was <0.5% for all conception groups and trimesters. The first trimesters of ART and OI pregnancies were more often exposed to Category D medicines than subfertile and fertile pregnancies, (ART = 4.9%, OI = 2.0% vs subfertile = 1.3%, fertile = 0.6%) as were later trimesters (ART = 3.4%, OI = 1.4% vs subfertile = 0.9%, fertile = 0.6%).ConclusionsThe overall prevalence of exposure to teratogenic medicines is low; however, exposure was greatest in pregnancies arising from ART and may be a modest contributing factor to the higher rate of birth defects observed among ART babies.
Congenital absence of vas deferens: Anatomical and embryological inputs from a series of autopsies reported in Europe throughout the 18th and 19th century

Published: December 2024

AbstractCongenital absence of the vas deferens (CAVD) is a syndrome with a heterogeneous presentation: bilateral (CBAVD) or unilateral (CUAVD), complete or partial and associated or not with other anomalies of the male urogenital system. A turning point came in 1968 when CBAVD was associated with cystic fibrosis and its CFTR gene mutations. Genetic studies then revealed that a minority of CBAVD but a majority of CUAVD are CFTR‐independent. In the literature, reference is classically made to two sources from the 18th and 19th century: Hunter and Reverdin. This scarcity prompted us to look for additional observations of CAVD. By a meticulous bibliographical search, we identified a corpus of 10 European observations (8 CUAVD and 2 CBAVD) some of them richly illustrated. They were collected between 1755 and 1876 throughout adult men autopsies. We also provided their primary and unambiguous sources. Analysis of the reported data revealed some interesting facts: both CBAVD cases were unlikely linked to cystic fibrosis and half of CUAVD cases were associated with an ipsilateral kidney absence, suggesting a CFTR‐independent pathophysiology. Moreover, the anatomical details of the anomalies raise interesting embryological questions we have tried to address in the light of current data. This work made it possible to identify new historical sources dealing with male genital tract pathologies. It sheds light on the origins of andrology and opens up interesting prospects for research and education in the field.

AbstractAimTo determine how gestational age at birth and postnatal growth relate to body composition in childhood.MethodsWe calculated conditional growth (birth‐2 years, 2 years‐6 years) and measured body composition at 2 and 6 years using bioelectrical impedance in cohorts of New Zealand children born very preterm (VPT; 23–31 weeks), late preterm (LPT; 35– <37 weeks) and term (≥37 weeks). We explored the relationships between growth and fat mass (FM) index and fat‐free mass (FFM) index at 6 years using multivariable linear regression.ResultsOf 1125 children (51% male), 202 were VPT, 114 LPT and 809 Term. Compared to Term, VPT but not LPT were lighter and shorter at 2 and 6 years and had lower FM index and FFM index. The association between weight growth from 2 to 6 years and both FM index and FFM index at 6 years was stronger than for weight growth from birth to 2 years or height growth at any period in all gestational age groups.ConclusionsSize and body composition at 2 and 6 years are different between infants born VPT, but not LPT, and at term. Later weight growth is more strongly associated with childhood body composition than earlier growth.
