AbstractDietary shifts may act to ease energetic constraints and allow organisms to optimise life-history traits.Heliconiusbutterflies differ from other nectar-feeders due to their unique ability to digest pollen, which provides a reliable source of amino acids to adults. Pollen-feeding has been associated with prolonged adult lifespan and increased fertility, yet there is a lack of empirical data demonstrating how pollen consumption influences key fitness traits, including chemical defences and adult body weight, as well as fertility over their elongated lifespan. Here, we investigated the effect of pollen-feeding on fertility, weight and chemical defences, as well as offspring defences, controlling for butterfly age and sex. Recently emergedHeliconius eratobutterflies of similar size were fed for 14 or 45 days on one of three diets: sugar solution only, or sugar solution replenished with either amino acid supplement or pollen. At the end of the experiment, oviposition assays were performed to evaluate fertility, and afterwards all butterflies and eggs were weighed and used for quantification of cyanogenic glucosides (CG). We found that there is an age-specific and sex-specific effect of pollen-feeding on butterfly weight, with both the sugar-only and amino-acid supplement diets reducing the weight of old females (45d), but not young females (14d) or males of any age. Females fed only sugar significantly reduced their egg-laying through adulthood, whereas females that had access to pollen maintained their fertility. Diet had a significant effect on the maintenance of the chemical defence of females, but not males. Curiously, even though females that have access to pollen were heavier, more toxic and laid more eggs, this did not translate into improvements in offspring defences, as eggs from butterflies of all ages and diet treatments had similar CG content. Our results emphasise the importance of controlling for age-specific and sex-specific effects in studies of life-history evolution and demonstrate that dietary novelty can relax energetic constraints.
Size and composition of haplotype reference panels impact the accuracy of imputation from low-pass sequencing in cattle

Published: January 2023

BackgroundLow-pass sequencing followed by sequence variant genotype imputation is an alternative to the routine microarray-based genotyping in cattle. However, the impact of haplotype reference panel composition and its interplay with the coverage of low-pass whole-genome sequencing data has not been sufficiently explored in typical livestock settings where only a small number of reference samples are available.MethodsSequence variant genotyping accuracy was compared between two variant callers, GATK and DeepVariant, in 50 Brown Swiss cattle with sequencing coverages ranging from 4 to 63-fold. Haplotype reference panels of varying sizes and composition were built with DeepVariant considering 501 cattle from nine breeds. High coverage sequencing data of 24 Brown Swiss cattle was downsampled to between 0.01- and 4-fold coverage to mimic low-pass sequencing. GLIMPSE was used to infer sequence variant genotypes from the low-pass sequencing data using different haplotype reference panels. The accuracy of the sequence variant genotypes imputed inferred from low-pass sequencing data was compared with sequence variant genotypes called from high-coverage data.ResultsDeepVariant was used to establish bovine haplotype reference panels because it outperformed GATK in all evaluations. Same-breed haplotype reference panels were better suited to impute sequence variant genotypes from low-pass sequencing than equally-sized multibreed haplotype reference panels for all target sample coverages and allele frequencies. F1 scores greater than 0.9, implying high harmonic means of recall and precision of called genotypes, were achieved with 0.25-fold sequencing coverage when large breed-specific haplotype reference panels (n = 150) were used. In absence of such large same-breed haplotype panels, variant genotyping accuracy from low-pass sequencing could be increased either by adding non-related samples to the haplotype reference panel or by increasing the coverage of the low-pass sequencing data. Sequence variant genotyping from low pass sequencing was substantially less accurate when the reference panel lacks individuals from the target breed.ConclusionsVariant genotyping is more accurate with Deep-Variant than GATK. DeepVariant is therefore suitable to establish bovine haplotype reference panels. Medium-sized breed-specific haplotype reference panels and large multibreed haplotype reference panels enable accurate imputation of low-pass sequencing data in a typical cattle breed.

AbstractOur understanding of the lymphatic vascular system lags far behind that of the blood vascular system, limited by available imaging technologies. We present a label-free optical imaging method that visualizes the lymphatic system with high contrast. We developed an orthogonal polarization imaging (OPI) in the shortwave infrared range (SWIR) and imaged both lymph nodes and lymphatic vessels of mice and ratsin vivothrough intact skin, as well as human mesenteric lymph nodes in colectomy specimens. By integrating SWIR-OPI with U-Net, a deep learning image segmentation algorithm, we automated the lymph node size measurement process. Changes in lymph nodes in response to cancer progression were monitored in two separate mouse cancer models, through which we obtained insights into pre-metastatic niches and correlation between lymph node masses and many important biomarkers. In a human pilot study, we demonstrated the effectiveness of SWIR-OPI to detect human lymph nodes in real time with clinical colectomy specimens.One Sentence SummaryWe develop a real-time high contrast optical technique for imaging the lymphatic system, and apply it to anatomical pathology gross examination in a clinical setting, as well as real-time monitoring of tumor microenvironment in animal studies.
Global patterns of plant form and function are strongly determined by evolutionary relationships

Published: January 2023

SummaryPlants display an incredible variety of forms and functions, which sustains a vast diversity of ecosystems on Earth. This diversity is the result of two forces: environmental filtering, the selection of phenotypes fit to a specific habitat; and evolutionary history, genetic constraints that determine the potential adaptations that species may evolve. To date, most studies have focused on describing macroecological patterns of trait variation, while the role of evolutionary history in determining these patterns has remained much less explored. Here, we combine a traits dataset including 4,213 vascular plant species with a phylogeny of the plant kingdom, to determine the influence of evolutionary history on the patterns of trait variation. Our results show that commonly used plant traits, such as plant height or leaf nitrogen, are strongly constrained by evolutionary history. Accounting for phylogenetic relationships changes the variance explained by the main axes of trait variation in the Plant Kindgom —the leaf economic spectrum and the plant size and organ axis continuum— with the former explaining more variance than the latter. Moreover, we demonstrate that the plant size continuum is more influenced by evolutionary history than the leaf economics spectrum. These results highlight the influence of evolutionary history in shaping plant life history strategies and the importance of accounting for phylogeny in trait-based studies.
Lead the African way!
Authors: Ramnund-Mansingh Aradhana , Naidoo Kiveshni 
Published: January 2023

PurposeCountries in Africa have undergone an unprecedented transformation that has shaped the continent as they move ahead from the clutches of colonialism. The evolution of leadership and how organisations function optimally has given rise to the review of leadership approaches and practices, revolutionising its position in the global markets. With the recent spate of global suffering from the pandemic, the formal and traditional work structures are becoming transient. At the same time, the economic consequences of the Russo-Ukrainian crisis have catastrophic effects globally.Design/methodology/approachThe research was conducted via a systematic review of scientific sources from various academic websites. Eligibility criteria were defined with the agreement of pertinent themes and concepts.FindingsBy evaluating and analysing characteristics and success indicators from the blend of leadership competencies ascertained from Afrocentric principles in response to African associated problems, Africa can cement its leadership concepts without following the global north principles. These philosophies are resilient enough to contend with a range of VUCA (volatility, uncertainty, complexity and ambiguity) complexities, including the impact of the recent global pandemic of immeasurable proportions and the prospect of war as the Russo-Ukrainian conflict intensifies.Originality/valueWithin the African environment, there is a greater focus on the human element in shared values, holistic well-being, cooperation and experience. The global community band together to deal with these complexities. This is a typical example of global connectedness with positive and negative connotations.

Authors: Imran Muhammad Kashif , Sarwar Ambreen , Fatima Tehreem , Iqbal Syed Muhammad Javed 
Published: January 2023

PurposeIn the current dynamic world, organizations required rapid changes to meet the increasing demands of their customers. On the other hand, the practice side claims that the majority of the organizational change attempts fail due to resistance from the employee side. Based on the behavioral theory of leadership, the authors examined the relationship between ethical leadership and organizational change with moderated mediation effect of behavioral resistance to change and commitment to change on the stated relationship.Design/methodology/approachData were obtained from 333 employees, selected at random, in three waves (i.e. pre-change, during change and post-change) using survey methods from services sector organizations operating in Pakistan.FindingsThe authors found that ethical leadership was positively linked to organizational change and this relation was partially mediated by the commitment to change. Further, behavioral resistance to change weakened the relationship between ethical leadership and commitment to change.Practical implicationsThe current study illuminates the importance of ethical leaders in the organizational change process, and empirical findings also gave an important direction to build change commitment in employees to reach positive results. Further, change leaders should use ethical practices in the workplace during organizational change initiatives to deal with behavioral resistance to change.Originality/valueThis study links ethical leadership with organizational change using the behavioral theory of leadership, an unexplored area in the existing literature that gives a new insight to academia and practice side officials to successfully implement any organizational change initiative.

Published: January 2023

PurposeThis study aimed to analyze the role of organizational learning capability and entrepreneurial orientation on frugal innovation and, consequently, operational performance within the Brazilian textile industry.Design/methodology/approachThe sample consisted of 257 valid questionnaires from the textile industry in the state of Santa Catarina, Brazil. Data were analyzed using structural equation modeling using SmartPLS software.FindingsThe results showed that organizational learning capability is a strong driver of the operational performance when mediated by frugal innovation. Evidence also showed that relationships between entrepreneurial orientation, organizational learning capability, frugal innovation and operational performance are significant once the direct effect has more power than the indirect effect. Results elucidated different outcomes that are not in accordance with previously seen studies. Moreover, the latter shines a light on a possible interference caused by the COVID-19 pandemic.Originality/valueThe study clarifies the relationship that entrepreneurial orientation and organizational learning capability unleash in frugal innovation and operational performance. It also shows a new situation when looking at the relationship between entrepreneurial orientation, organizational learning capability and operational performance.

Authors: Fabian Khristin , Taylor-Smith Ella , Smith Sally , Bratton Andrew 
Published: January 2023

PurposeThe purpose of this study is to gain insight into the degree apprenticeship labour market and employers' strategies for apprenticeship recruitment using job advertisement data. Specifically, this study identifies the skills, attributes, experience and qualifications that employers look for in IT apprentices. The study also identifies the salaries and responsibilities of apprentices and considers the alignment between the advertised jobs and apprenticeship definitions.Design/methodology/approachDegree apprenticeship job adverts (n = 290) were collected from the official websites used by employers in England and Scotland to advertise apprenticeship roles, between March 2019 and March 2020. Data was analysed using content analysis to systematically elicit salaries, candidate requirements in terms of skills, qualifications and experience and specific job details from these adverts.FindingsA wide variation in advertised salary was found. Entry routes were similar to the traditional high school qualifications (A-levels or Highers) sought by universities. The skills and attributes being sought at recruitment were the same skills that employers were seeking in graduates and the same skills that the apprenticeships were designed to develop. Most adverts focused on the training that the apprentices would be receiving, rather than work tasks, which were rarely specified.Originality/valueThis is the first study of how apprenticeship roles are advertised to potential candidates and thus contributes to ongoing research into this new work/degree-level education model. By analysing job adverts we share insights into how employers position apprenticeships to attract candidates.

How to improve firm performance? – The role of production capabilities and routines
Authors: Csiki Ottó , Demeter Krisztina , Losonci Dávid 
Published: January 2023

PurposeIn the multilayered capability framework the authors integrate two layers, namely functional level production capabilities and shop floor-level production routines (PRs). The authors examine how these two layers are interlinked, and additionally, they explore how these layers contribute to firm performance.Design/methodology/approachThe authors tested the hypotheses using structural equation modeling (SEM) on a sample of manufacturing firms.FindingsRegarding the capability layers, the authors found that at the functional level, production dynamic capabilities (PDCs) drive the renewal of production ordinary capabilities (POCs), and that at the shop floor level, deployment of Industry 4.0 (I4.0) is influenced by lean production. Regarding the direct links between capability layers, the authors showed that PDCs and POCs have different roles in shaping shop floor PRs: PDCs is linked to I4.0, and lean methods is impacted by POCs. Concerning performance implications, only PDC and POC have significant impact on firm performance (the latter is negative), while PRs do not.Research limitations/implicationsAlthough, contextual factors (e.g. technology intensity, size) do not influence our findings, the potential country-effect and the dominance of medium-sized firms offer future research directions.Practical implicationsIf production managers want to contribute to business performance, they should be more susceptible to resource renewal (PDCs) than to their general (POCs) or specific (PRs) exploitation efforts. As they exploit current resource stocks, they face a trade-off: they must consider that beyond their positive impacts on operational performance, their implications on business performance will be controversial.Originality/valueScholars usually examine one layer of capabilities, either capabilities or routines, and associate that with one dimension of performance, either financial and market measures or operational indicators. The authors propose a multilayered capability framework with a complex view on performance implications.
Double-objective economic statistical design of (X ‾) control chart using Linex loss function

Published: January 2023

PurposeThe purpose of this paper is to develop a double-objective economic statistical design (ESD) of (X ‾) control chart under Weibull failure properties with the Linex asymmetric loss function. The authors have expressed the probability of type II error (β) as the statistical objective and the expected cost as the economic objective.Design/methodology/approachThe design used in this study is based on a double-objective economic statistical design of (X ‾) control chart with Weibull shock model via applying Banerjee and Rahim's model for non-uniform and uniform schemes with Linex asymmetric loss function. The results in the least average cost andβin uniform and non-uniform schemes by Linex loss function, compared with the same schemes without loss function.FindingsNumerical results indicate that it is not possible to reduce the second type of error and costs at the same time, which means that by reducing the second type of error, the cost increases, and by reducing the cost, the second type of error increases, both of which are very important. Obtained based on the needs of the industry and which one has more priority has the right to choose. These designs define a Pareto optimal front of solutions that increase the flexibility and adaptability of theX ‾control chart in practice. When the authors use non-uniform schemes instead of uniform schemes, the average cost per unit time decreases by an average and when the authors apply loss function, the average cost per unit time increases by an average. Also, this quantity for double-objective schemes with loss function compared to without loss function schemes in cases uniform and non-uniform increases. The reason for this result is that the model underestimated the costs before using the loss function.Practical implicationsThis research adds to the body of knowledge related to flexibility in process quality control. This article may be of interest to quality systems experts in factories where the choice between cost reduction and statistical factor reduction can affect the production process.Originality/valueThe cost functions for double-objective uniform and non-uniform sampling schemes with the Weibull shock model based on the Linex loss function are presented for the first time.

Published: January 2023

PurposeDespite its importance, the literature on women financial inclusion (WFI) remains fragmented due to the absence of a comprehensive review that consolidates the intellectual structure of the field. This paper examines the intellectual structure of the topic and gives a complete overview of the research undertaken so far in the field.Design/methodology/approachA bibliometric study of 235 Scopus-indexed publications, including citation analysis, keyword network analysis, co-authorship analysis and reference co-citation analysis using VOSviewer was performed.FindingsThe study identified major contributors to the field (the most prolific author was Ghosh, S.), the leading journals in the field (the World Development), the geographical locations where research in the field is concentrated (India is the leading country) and the organisations focussing on green consumer research (leading organisation: The World Bank, USA). In addition, four significant themes that describe the body of information about women's financial inclusion were found.Originality/valueThis study provides policymakers and academic scholars with fresh insights at a higher level into this burgeoning topic. Such insights would aid in the development of initiatives to address women's financial inclusion concerns.Peer reviewThe peer review history for this article is available at: https://publons.com/publon/10.1108/IJSE-06-2022-0438.
