A guided tour through the qualitative research city
Authors: Wieland Andreas , Tate Wendy L. , Yan Tingting 
Published: January 2024

AbstractThis article argues for the expansion of qualitative research approaches in supply chain management (SCM). By comparing mainstream qualitative approaches to popular Parisian landmarks, it argues that just as tourists can miss the city's essence by visiting only famous sites, SCM researchers limit their understanding by relying solely on conventional approaches. It emphasizes that, much like exploring lesser‐known parts of a city, incorporating diverse qualitative approaches can enrich SCM research. Highlighting the dominance of realist and positivist approaches, the article calls for greater inclusion of nominalist and anti‐positivist approaches. It introduces different “buildings” of qualitative research (grounded theory, interpretive research, sensemaking, sociomateriality, actor–network theory, ethnography, action research, discourse analysis, narrative research, and historical research), each offering unique insights into SCM. The article argues that embracing these diverse approaches can lead to a deeper understanding of complex global supply chain phenomena and encourage innovative theoretical development, thereby broadening the scope and impact of the discipline.
Toddlers’ Verb‐Marking Errors Are Predicted by the Relative Frequency of Uninflected Sequences in Well‐Formed Child‐Directed Speech: A Preregistered Corpus Analysis
Authors: Sawyer Hannah , Bannard Colin , Pine Julian 
Published: January 2024

AbstractVerb‐marking errors such as she play football and daddy singing are a hallmark feature of English‐speaking children's speech. We investigated the proposal that these errors are input‐driven errors of commission arising from the high relative frequency of subject + unmarked verb sequences in well‐formed child‐directed speech. We tested this proposal via a preregistered corpus analysis and asked at what level the effects occur: Is it the relative frequency of specific subject + unmarked verb sequences in the input that is important, or is it simply that verbs become entrenched, such that their frequency of appearance with any third person singular subject accounts for errors? We found that the best predictor of children's verb‐marking errors is the relative frequency of unmarked forms of specific subject + verb sequences. Our results supported the proposal that children's apparent omissions of certain grammatical morphemes are in fact input‐driven errors of commission and provided insight into the mechanisms by which this occurs.

Published: January 2024

AbstractUrban high‐speed railway construction is complex due to limited land resources, high population density, and potential construction risks, especially when new tracks are parallelly aligned to operational railways. Addressing a gap in current literature on fine optimization of manual alignment in such scenarios, this paper introduces a biobjective approximate fine‐grained optimization model for railway alignments (BA‐FORA). Utilizing an approximate dynamic programming (ADP) method, BA‐FORA effectively searches the feasible region to approach a global optimum, overcoming the dimensionality challenges inherent in standard dynamic programming (DP). This paper presents a biobjective optimization framework that takes into account both construction cost and construction risk adjacent to existing operating railways (CRAEOR), offering a method for the fine‐grained design of new railways adjacent to existing railways. Finally, the proposed BA‐FORA framework is applied to practical cases, demonstrating its superior optimization performance. The findings indicate that the BA‐FORA model can autonomously investigate and enhance railway alignment. It generates cost‐effective and low‐risk solutions exceeding manual efforts, ensuring alignment constraint compliance.

SummaryWolfberry is a plant with medicinal and food values. However, its bioactive ingredients and the corresponding genetic bases have not been determined. Here, we de novo generated a chromosome‐level genome assembly for wolfberry, yielding a genome sequence of ~1.77 Gb with contig N50 of 50.55 Mb and 39 224 predicted gene models. A variation map, using 307 re‐sequenced accessions, was called based on this genome assembly. Furthermore, the fruit metabolome of these accessions was profiled using 563 annotated metabolites, which separated Lycium barbarum L. and non‐L. barbarum L. The flavonoids, coumarins, alkaloids and nicotinic acid contents were higher in the former than in the latter. A metabolite‐based genome‐wide association study mapped 156 164 significant single nucleotide polymorphisms corresponding to 340 metabolites. This included 19 219 unique lead single nucleotide polymorphisms in 1517 significant association loci, of which three metabolites, flavonoids, betaine and spermidine, were highlighted. Two candidate genes, LbUGT (evm.TU.chr07.2692) and LbCHS (evm.TU.chr07.2738), with non‐synonymous mutations, were associated with the flavonoids content. LbCHS is a structural gene that interacts with a nearby MYB transcription factor (evm.TU.chr07.2726) both in L. barbarum and L. ruthenicum. Thus, these three genes might be involved in the biosynthesis/metabolism of flavonoids. LbSSADH (evm.TU.chr09.627) was identified as possibly participating in betaine biosynthesis/metabolism. Four lycibarbarspermidines (E–G and O) were identified, and only the lycibarbarspermidines O content was higher in L. barbarum varieties than in non‐L. barbarum varieties. The evm.TU.chr07.2680 gene associated with lycibarbarspermidines O was annotated as an acetyl‐CoA‐benzylalcohol acetyltransferase, suggesting that it is a candidate gene for spermidine biosynthesis. These results provide novel insights into the specific metabolite profile of non‐L. barbarum L. and the genetic bases of flavonoids, betaine and spermidine biosynthesis/metabolism.
FIONA1‐mediated mRNA m6A methylation regulates the response of Arabidopsis to salt stress
Authors: Cai Jing , Hu Jianzhong , Xu Tao , Kang Hunseung 
Published: January 2024

AbstractN6‐methyladenosine (m6A) is an mRNA modification widely found in eukaryotes and plays a crucial role in plant development and stress responses. FIONA1 (FIO1) is a recently identified m6A methyltransferase that regulates Arabidopsis (Arabidopsis thaliana) floral transition; however, its role in stress response remains unknown. In this study, we demonstrate that FIO1‐mediated m6A methylation plays a vital role in salt stress response in Arabidopsis. The loss‐of‐function fio1 mutant was sensitive to salt stress. Importantly, the complementation lines expressing the wild‐type FIO1 exhibited the wild‐type phenotype, whereas the complementation lines expressing the mutant FIO1m, in which two critical amino acid residues essential for methyltransferase activity were mutated, did not recover the wild‐type phenotype under salt stress, indicating that the salt sensitivity is associated with FIO1 methyltransferase activity. Furthermore, FIO1‐mediated m6A methylation regulated ROS production and affected the transcript level of several salt stress‐responsive genes via modulating their mRNA stability in an m6A‐dependent manner in response to salt stress. Importantly, FIO1 is associated with salt stress response by specifically targeting and differentially modulating several salt stress‐responsive genes compared with other m6A writer. Collectively, our findings highlight the molecular mechanism of FIO1‐mediated m6A methylation in the salt stress adaptation.
Real‐time generation of spherical panoramic video using an omnidirectional multi‐camera system

Published: January 2024

AbstractThis paper presents a novel method for real‐time generation of seamless spherical panoramic videos from an omnidirectional multi‐camera system (OMS). Firstly, a multi‐view video alignment model called spherical projection constrained thin‐plate spline (SP‐TPS) was established and estimated using an approximately symmetrical seam‐line, maintaining the structure inconsistency around the seam‐line. Then, a look‐up table was designed to support real‐time processing of video re‐projection, video dodging and seam‐line updates. In the table, the overlapping areas in OMS multi‐view videos, the seam‐lines between spherical panoramas and OMS multi‐view videos and the pixel coordinate mapping relationship between spherical panoramas and OMS multi‐view videos were pre‐stored as a whole. Finally, a spherical panoramic video was outputted in real‐time through look‐up table computation under an ordinary GPU processor. The experiments were conducted on multi‐view video taken by “1 + 4” and “1 + 7” OMS, respectively. Experimental results demonstrate that compared with four state‐of‐the‐art methods reported in the literature and two bits of commercial software for video stitching, the proposed method excels in eliminating visual artefacts and demonstrates superior adaptability to scenes with varying depths of field. Assuming that OMS is not movable in the scene, this method can generate seamless spherical panoramic videos with a resolution of 8 K in real time, which is of great value to the surveillance field.
Knowability paradox, decidability solution?
Authors: Knowles William Bondi 
Published: January 2024

AbstractFitch's knowability paradox shows that for each unknown truth there is also an unknowable truth, a result which has been thought both odd in itself and at odds with views which impose epistemic constraints on truth and/or meaningfulness. Here a solution is considered which has received little attention in the debate but which carries prima facie plausibility. The decidability solution is to accept that Fitch sentences are unknowably true but deny the significance of this on the grounds that Fitch sentences are nevertheless decidable. The decidability solution is particularly attractive for those whose primary concern is an epistemic constraint on meaningfulness (‘verificationists’). For those whose main concern is truth (‘anti‐realists’), the situation is more complex: Melia takes the solution to exonerate anti‐realism completely; Williamson sees it as completely irrelevant. The truth lies between these two extremes: there is one broad anti‐realist commitment to which the solution does not apply, but there is also one, the “fundamental tenet” of anti‐realism according to Dummett, to which it does.
Estimation of direct and maternal covariance along with genetic and phenotypic trends of reproduction traits in Murrah buffalo

Published: January 2024

AbstractThe research utilized data from 662 Murrah buffaloes meticulously recorded over 24 years (1996–2019) from historical pedigree sheets maintained at the buffalo farm of the Department of Livestock Production and Management (LPM) at Lala Lajpat Rai University of Veterinary and Animal Sciences (LUVAS), Hisar. A series of six univariate animal models were employed to calculate estimates of (co)variance components and heritability for first lactation reproduction traits. Among these models, Model 2 was identified as the best fit for age at first calving (AFC) and calving interval (CI), while Model 1 proved optimal for service period (SP) and conception rate (CR). The heritability estimates for AFC, SP, CR and CI across the models were ranged between 0.11 and 0.32, 0.01 and 0.03, 0.05 and 0.06, and 0.01 and 0.06, respectively. Maternal effects (m2) were observed in AFC and CI, ranging from 0.10 to 0.20 and 0.01 to 0.03, respectively. Across all three traits, there was a consistent negative genetic correlation (−0.75 to −0.92) between direct additive and maternal effects. The breeding values for AFC, SP, CR and CI varied within specific ranges from −32.85 to 44.33 days, −15.61 to 28.42 days, −7.41 to 6.48% and −20.64 to 35.79 days, respectively. Significantly, Spearman's rank correlation analysis revealed highly significant relationships (p < .01) between the breeding values of different models, indicating strong and consistent associations within these traits. These findings underscore the stable and reliable connections observed within the breeding values for these essential reproductive traits across the various models used in the study. The majority of reproductive traits showed favourable negative trends, indicating a positive outcome. A decrease in AFC, SP and CI suggests an extended economic life for the animals. Additionally, the upward trends in CR reflect positive indications of effective management practices and skilled operational procedures.
Labor supply responses to rainfall shocks
Authors: Maitra Pushkar , Tagat Anirudh 
Published: January 2024

AbstractAgricultural production in developing countries is heavily rainfall dependent. Any unexpected variation in rainfall can affect the welfare of households. Using unit record data from India, this paper shows that households can insure against agricultural productivity (rainfall) shocks. Evidence suggests that they do so by varying the time allocation of individual members to different activities, particularly to regular wage work and human capital accumulation. There is a gender‐differentiated aspect to this response. Rainfall shocks adversely affect women's human capital accumulation. While there is no evidence that households use participation in NREGS to insure against rainfall shocks, the availability of NREGS helps reduce the impact of rainfall shocks on human capital accumulation.

Published: January 2024

AbstractGaining the inside perspective of an elite athlete throughout the competitive season provides a unique approach to understand the lived experience during multiple competitive events. The purpose of the present study was to investigate how elite disc golf athletes perceive and interpret their experiences of performing during various training and competitive events over the course of an elite disc golf season. Two elite disc golf athletes, one man and one woman, were recruited using homogeneous purposive sampling. The participants were interviewed three times and observed during three competitive events, as well as before and after a training session. A longitudinal interpretative phenomenological analysis (LIPA) was adopted to capture temporal and dynamic changes of the participants' lived experiences. The findings illustrated the athletes' personal experiences of performing during competitive disc golf events, with both athletes' experiences of competition changing during the season. Their competitive experiences appear to relate to the meaning disc golf has for the athletes, which in this study had both an experiential and existential level of meaning over time. Such a finding illustrates the importance of honoring athletes' unique experiences in making sense of their performances during an elite disc golf season. Taking the time to understand athletes' perceptions of their personal experiences appear important in attempting to understand their sense‐making of their hot cognition before, during, and after competitions.

Published: January 2024

AbstractBackgroundAllergen testing is used to select antigens included in the desensitisation vaccine. Intradermal skin test (IDT) is the gold standard in cats, yet allergen‐specific immunoglobulin (Ig)E serological testing (ASIS) is often used. Feline data are lacking regarding the agreement between IDT and ASIS results.Hypothesis/ObjectivesThe first objective of the study was to establish a colony of cats with naturally acquired feline atopic syndrome (FAS). Further objectives were to define their hypersensitivity disorder to detail the allergen tests results, and to assess similarity between the allergen tests.AnimalsThirty‐five cats with FAS and 10 control cats.Materials and MethodsEnrolled cats went through a five phase‐screening and quarantine process before joining the colony. An elimination diet trial was performed on all FAS cats. ASIS and IDT were consecutively performed on all cats under sedation.ResultsReactions to 34 allergens were compiled for the 45 cats. Global sensitivity and specificity of ASIS were 34.7% and 78.9%, respectively. Only flea (ICC = 0.26, p = 0.040) and Dermatophagoides pteronyssinus (ICC = 0.48, p < 0.001) allergens had a significant intraclass correlation (weak agreement). Two FAS cats had negative tests including one cat with a concomitant food allergy.Conclusions and Clinical RelevanceThis study depicts the first reported colony of cats with naturally acquired FAS. This is the first feline study to compare and show the poor agreement between allergen tests with a panel of 34 allergens. This colony also harbours two cats with FAS with negative allergen tests. These may represent the first described cats with an intrinsic form of atopic syndrome.
An approximate solution of singularly perturbed problem on uniform mesh
Authors: Arslan Derya , Çelik Ercan 
Published: January 2024

In this study, we obtain approximate solution for singularly perturbed problem of differential equation having two integral boundary conditions. With this purpose, we propose a new finite difference scheme. First, we construct this exponentially difference scheme on a uniform mesh using the finite difference method. We use the quasilinearization method and the interpolating quadrature formulas to establish the numerical scheme. Then, as a result of the error analysis, we show that the method under study is convergent in the first order. Consequently, theoretical findings are supported by numerical results obtained with an example. Approximate solutions curves are compared on the chart to provide concrete indication. The maximum errors and convergence rates obtained are given on the table for different varepsilon and N values.
Parametric Vibration and Combined Resonance of a Bending-Torsional Coupled Turbine Blade With a Preset Angle

Published: January 2024

Abstract
The parametric vibration and combined resonance of a turbine blade with a preset angle subjected to the combined effect of parametric and forced excitation were investigated. The blade was modeled as a rotating beam considering the effects of centrifugal, gyroscopic, and bending-torsion coupling. The instability region of the corresponding linear system with parametric excitation was analyzed using Floquet theory, and the effect of blade parameters on this region was discussed. Notably, the parametric vibration of the torsional degree-of-freedom (DOF) caused by parametric excitation of the bending degree-of-freedom has been found. The results show that the size and position of the parameter resonance region are affected by the blade aspect ratio and preset angle, respectively. Furthermore, the multiscale method was employed to solve the blade equation under the combined action of parametric and forced excitation to study the combined resonance caused by forced excitation and gyroscopic items. The effect of blade parameters and excitation characteristics on regions of combined resonance were investigated. The phenomenon of heteroclinic bifurcation was observed due to changes in the excitation frequency, and the harmonic components that accompanied the bifurcation changed. Specifically, a multiperiod response dominated by the excitation frequency and subharmonic components shifted to a single-period response dominated by subharmonic components. This study provides a theoretical explanation for the nonsynchronous resonance of blades and the subharmonic signals in blade vibration and guides blade parameter design, especially for wind turbines.

Published: January 2024

The aim of this study was to determine factors associated with participation of community-dwelling older Australians (≥65 years) in the Exercise Right for Active Ageing program, consisting of 12 low- to moderate-intensity group exercise classes, delivered weekly, in person or online, by accredited exercise scientists and physiologists across Australia. Out of 6,949 participants recruited, 6,626 (95%) attended one or more classes and were included in the primary analysis, and 49% of participants attended all 12 classes. Factors associated with higher class attendance included participation in yoga/flexibility/mobility classes, attendance at a free trial class (adjusted incidence rate ratio [95% confidence interval]: 1.05 [1.03, 1.08]), and attending online classes (1.19 [1.11, 1.26]). Factors associated with lower class attendance included state of residence, living in inner regional areas (0.95 [0.93, 0.98]), and having two or more comorbidities (0.97 [0.95, 0.99]). High class attendance suggests that the Exercise Right for Active Ageing program was well received by older Australians, particularly in states less impacted by COVID-19 lockdowns.
