Rare whiskies' market: new Eldorado for investors and collectors?
Authors: Le Fur Eric 
Published: April 2023

PurposeThis article aims to analyze the relationships between the different categories of rare whiskies and the opportunities for investors and collectors.Design/methodology/approachThis article uses indices representative of collectors, market performance and specific from 2008–2022 to a distillery and determine the returns. The author performs stationarity tests, cointegration procedures and the Granger non-causality test.FindingsThe results of this article indicates that average returns are positive. In addition, there is a wide range of annual returns, i.e. strongly negative and positive, leading to possible speculation over short periods. High and heterogeneous volatility accompanies these potential gains. The correlations between the different returns of rare whisky are close to zero, indicating potential gains in terms of portfolio diversification. This result is crucial for investors-speculators that benefit from an additional alternative asset. Cointegration relationships are more numerous in the short run than in the long run, confirming that rare whisky could present potential gains for investors, as collectors have in-depth knowledge of the relationships between the different markets.Originality/valueFinally, the author discusses the implications for different categories of economic actors (investors, collectors, sellers and producers).

Authors: Anantha Krishnan Akila , Sengupta Angan 
Published: April 2023

PurposeThis study examines the influence of the ownership structure of banks on investors' behavior by dissecting the investors' response to news regarding performance indicators in private and government-owned banks.Design/methodology/approachThe event study methodology is used for the analysis. The data for 35 banks (out of 38), listed on the National Stock Exchange (NSE) for a duration of 230 months (January 2001 to February 2020) is collected. A set of cross-sectional regression analyses is done to identify variables influencing the returns under differential circumstances.FindingsPrivate banks seem to display a sharper response to negative changes in earnings, while government-owned banks show a more robust reaction to a positive change. The contrast is seen in the variables, having a bearing on the abnormal returns After controlling for a set of factors, the regression analysis shows the ownership structure may not matter on abnormal returns (on event day), the factors such as a change in quarterly earnings, firm-size and three-year average-sales growth influence the positive and negative changes in abnormal returns of government banks, and predictability for private banks is found to be poor regarding selected indicators.Originality/valueThe study evaluates the role of ownership structure on the heterogeneity in investors' responses to the financial performance of banks, thereby assisting in designing strategies to ensure the optimal outcome around the quarterly earnings announcements.

Purpose
Gamification appears to be one of the most important levers for improving performance and engagement in training programs. Moreover, gamification has been considered as critical to researchers in organizational learning. The main purpose of this study is to provide a general overview of gamification studies in the organizational context.

Design/methodology/approach
This systematic literature review has been synthesized by reviewing the majority of literature reviews as well as carefully selected primary research studies published between 2010 and 2020.

Findings
The result of the study revealed that gamification has become a popular technique to improve employee and organizational capabilities. The features of the gamification have been reviewed from three mechanics, dynamics and aesthetics perspectives. Additionally, three primary, middle and optimal affordances and core functions of gamification in organizational learning have been identified and examined.

Originality/value
This paper fills a gap in the literature regarding the gamification field for systematic review results in an organizational learning context.
Reproductive challenges related to a complex sexual system in Euphorbia rosescens, a rare endemic herb
Authors: Faivre Amy E. , Smith Stacy A. 
Published: April 2023

AbstractWhen the sexual system of a rare plant species is complex, characterizing floral development, plant morphology, and subpopulation structure is essential for assessing reproductive potential. Availability of pollinator rewards and positioning of sexual morphs within inflorescences relates to outcrossing potential. We studied the complex sexual system of the recently discovered Euphorbia rosescens E.L. Bridges & Orzell, a rare species occurring in a single Florida county. Euphorbia rosescens has both monomorphic subpopulations of female plants and mixed subpopulations with male and andromonoecious plants. Most data on cyathia sex, inflorescence architecture, floral visitors, and fruit set came from one female subpopulation and one mixed subpopulation. Cyathia longevity, flowering phase, nectar secretion, pollen production, and viability were measured in female, male, and hermaphrodite cyathia. Female plants had fewer inflorescence levels and cyathia and significantly smaller cyathia than male and andromonoecious plants. Andromonoecious plants were larger and produced more cyathia relative to male plants. Within mixed populations, sex switching occurred in both directions between male and andromonoecious plants. Female plants did not switch sexes. Proximal to distal inflorescence levels transitioned from hermaphrodite to male cyathia on andromonoecious plants. Nectar secretion corresponded to initiation of staminate flowering, but in female cyathia stigmas were receptive approximately a day before nectar secretion. Pollen production and viability were similar in male and hermaphrodite cyathia. Fruit maturation was minimal, primarily observed on andromonoecious plants. Nectar availability, pollen rewards, trimorphic inequalities in inflorescence display, and low fruit set suggest high geitonogamy, thus limiting outcrossing potential for this species.
Oxic–anoxic cycling promotes coupling between complex carbon metabolism and denitrification in woodchip bioreactors

Published: April 2023

AbstractDenitrifying woodchip bioreactors (WBRs) are increasingly used to manage the release of non‐point source nitrogen (N) by stimulating microbial denitrification. Woodchips serve as a renewable organic carbon (C) source, yet the recalcitrance of organic C in lignocellulosic biomass causes many WBRs to be C‐limited. Prior studies have observed that oxic–anoxic cycling increased the mobilization of organic C, increased nitrate (NO3−) removal rates, and attenuated production of nitrous oxide (N2O). Here, we use multi‐omics approaches and amplicon sequencing of fungal 5.8S‐ITS2 and prokaryotic 16S rRNA genes to elucidate the microbial drivers for enhanced NO3− removal and attenuated N2O production under redox‐dynamic conditions. Transient oxic periods stimulated the expression of fungal ligninolytic enzymes, increasing the bioavailability of woodchip‐derived C and stimulating the expression of denitrification genes. Nitrous oxide reductase (nosZ) genes were primarily clade II, and the ratio of clade II/clade I nosZ transcripts during the oxic–anoxic transition was strongly correlated with the N2O yield. Analysis of metagenome‐assembled genomes revealed that many of the denitrifying microorganisms also have a genotypic ability to degrade complex polysaccharides like cellulose and hemicellulose, highlighting the adaptation of the WBR microbiome to the ecophysiological niche of the woodchip matrix.
Development and initial validation of the Sources of Reading Self‐Efficacy Scale for College and University Students (SOURSES‐C)
Authors: Pei Yalian , O'Brien Katy H. 
Published: April 2023

BackgroundTo examine levels of reading self‐efficacy in college students and further understand sources that foster reading self‐efficacy at the postsecondary level, there is a need for a valid scale that can be used for college student populations.MethodsIn Phase 1, 160 items were generated and reviewed by a panel of experts and a group of undergraduate students. Of these, 48 items reached consensus for acceptance and were retained for Phase 2 pilot testing. Pilot results were analysed with principal component analysis to identify the scale structure and remove items not strongly associated with components. Phase 3 finalised the scale and confirmed construct validity using confirmatory factor analysis as well as internal reliability with Cronbach's α. Phase 4 further assessed construct validity through sensitivity analyses that control for age, gender, education level, ethnicity and grade point average (GPA) to evaluate the potential impact of these covariates on model fit. In addition, Phase 4 assessed the relationships between reading self‐efficacy and similar constructs (i.e., academic self‐efficacy and reading performance) to evaluate convergent validity of the final scale.ResultsBased on Phase 2 principal component analysis, three components were retained: ‘effort’, ‘enjoyment’, and ‘processing’. After removing items with high covariance indicated by the Phase 3 testing, the final scale included 15 items. The Sources of Reading Self‐Efficacy Scale for College and University Students (SOURSES‐C) was significantly correlated with reading performance, GPA and general academic self‐efficacy.ConclusionsSOURSES‐C is a valid and reliable tool to describe sources of reading self‐efficacy in college students. Understanding of reading self‐efficacy profiles may inform further investigations to improve motivation and persistence, self‐regulation and strategy use during reading.
The natural rate of interest of Hong Kong
Authors: He Yunlu , Wang Bin 
Published: April 2023

AbstractWe measure the natural rate of interest of Hong Kong in a flexible VAR model. We find that the natural rate of interest of Hong Kong fell below zero after the SARS shock in 2003 and reached the lowest after the great recession in 2007–2009. Variance decomposition shows that mainland China, instead of the USA, has a larger impact on the natural rate of interest of Hong Kong.

Published: April 2023

AbstractThe shedder status of a person is an important consideration when evaluating probabilities of DNA transfer during activity‐level assessments. As an extension of our previously published study, the shedder statuses of 38 individuals were reassessed 1 year later. The study found that shedder status may change over time for some individuals and was associated with one's gender, number of items touched, and mobile phone usage. In 29% of touch events, no DNA allele was detected and in 99% of touch events, the amount of DNA deposited was <2 ng. The study also found that in 0.6% of touch events, the participant could be excluded as a contributor of the observed DNA profile, with another person being included. Additionally, our investigations suggest that the current three‐category system for shedder status classification may require further refinement to better represent the individuals' shedder status in a population.
Ichthyoplankton metabarcoding: An efficient tool for early detection of invasive species establishment

Published: April 2023

AbstractDetection of invasive species is critical for management but is often limited by challenges associated with capture, processing and identification of early life stages. DNA metabarcoding facilitates large‐scale monitoring projects to detect establishment early. Here, we test the use of DNA metabarcoding to monitor invasive species by sequencing over 5000 fishes in bulk ichthyoplankton samples (larvae and eggs) from four rivers of ecological and cultural importance in southern Canada. We were successful in detecting species known from each river and three invasive species in two of the four rivers. This includes the first detection of early life‐stage rudd in the Credit River. We evaluated whether sampling gear affected the detection of invasive species and estimates of species richness, and found that light traps outperform bongo nets in both cases. We also found that the primers used for the amplification of target sequences and the number of sequencing reads generated per sample affect the consistency of species detections. However, these factors have less impact on detections and species richness estimates than the number of samples collected and analysed. Our analyses also show that incomplete reference databases can result in incorrectly attributing DNA sequences to invasive species. Overall, we conclude that DNA metabarcoding is an efficient tool for monitoring the early establishment of invasive species by detecting evidence of reproduction but requires careful consideration of sampling design and the primers used to amplify, sequence and classify the diversity of native and potentially invasive species.
Impacts of U.S. countervailing duties on phosphate fertilizers
Authors: Beeler Ashley , Schaefer K. Aleks , Sestak Jacob , Conover Glenn 
Published: April 2023

AbstractCountervailing duties are a trade policy instrument by which importing governments tax imports that are found to benefit from foreign subsidies. Thus, in effect, these duties attempt to remedy market distortions generated by foreign subsidies by further distorting market mechanisms. On March 11, 2021, the U.S. International Trade Commission issued duties ranging between 19.97% and 47.05% on Moroccan phosphate imports upon finding that Moroccan exports had been receiving unfair government subsidies. In this research, we estimate the impacts of these duties on U.S. diammonium phosphate and triple superphosphate fertilizers, as well as long‐run downstream prices of five U.S. row crops with the largest phosphate usage. Using these results, we assess the implications for gross receipts in the U.S. fertilizer industry and gross margins for American farmers. We also calculate the implied change in expenditure for agricultural end users. We find that the countervailing duties have increased U.S. phosphate fertilizer prices by approximately 34% over counterfactual levels. This corresponds to an expected downstream price response ranging from around 10% for corn, cotton, and sorghum to between 1% and 4% for soybeans and wheat. This market distortion generates a $23 billion increase in gross receipts for a concentrated domestic fertilizer industry while shrinking gross margins for American farmers by 2% and 8% and increasing agricultural user expenditures by approximately $10.84 billion.

Authors: Ford Jemma , Hince Dana , Lee Emmeline , Lo Glen 
Published: April 2023

BackgroundTransvaginal hysterosalpingo‐foam sonography (HyFoSy) assesses tubal patency in an outpatient setting and without ionising radiation, unlike traditional hysterosalpingography (HSG) under fluoroscopy. Like HSG, HyFoSy may be complicated by uterine intramural contrast leak, leading to venous intravasation. Intravasation of particulate contrast agents risks pulmonary or cerebral emboli.AimsWe aimed to assess the intravasation rate of HyFoSy using ExEm® Foam and association with endometrial thickness, ExEm® Foam volume, uterine length, adenomyosis severity, uterine morphology or pain score.MethodsAn ethics‐approved retrospective study on all HyFoSy examinations between 23 January 2018 and 27 October 2021 on sub‐fertile patients, trying to conceive.Initial transvaginal sonography confirmed anatomy, uterine morphology, adenomyosis severity and endometrial thickness. Subspecialist radiologists performed HyFoSy with sonographer assistance. Intravasation was identified in real time but also checked for afterwards. Patients were asked to rate instillation pain/discomfort from one to ten immediately afterward.ResultsFour hundred and thirty‐six (n = 436) patients met inclusion criteria. Thirty (6.9%) experienced intravasation. Endometrial thickness and pain score were associated with intravasation. For every millimetre increase in endometrial thickness, the odds of intravasation decreased by 26% (P = 0.010). For every point increase on the pain scale, the odds of intravasation increased by 22% (P = 0.032). There was no evidence of an association between instilled ExEm® Foam volume or the other previously published parameters with intravasation.ConclusionA 6.9% rate of intravasation was observed. Both endometrial thickness and pain score were significantly associated with intravasation. There was no evidence of an association between ExEm® Foam volume and intravasation.

Published: April 2023

BackgroundWhereas symptomatic endometriosis may affect work performance, the impact of endometriosis in the general community is not known.AimsThe associations between endometriosis and each of sick leave and work ability, were investigated in a large sample of non‐healthcare seeking women.Materials and MethodsThis community‐based, cross‐sectional study recruited 6986 women, aged 18–39 years, from three eastern states of Australia between 11 November 2016 and 21 July 2017. Women were identified as having endometriosis if they had undergone a pelvic ultrasound and reported a diagnosis of endometriosis. Working women completed the Work Ability Index.ResultsParticipants were predominantly of European ancestry (73.1%) and 46.8% were overweight or had obesity. The prevalence of endometriosis was 5.4% (95%CI 4.9–6.0%) with the highest prevalence of 7.7% (95%CI 6.5 to 9.1%) for women aged 35–39 years. Among the 4618 working women, those with endometriosis had significantly more sick days from work (33.6% reported ≥10 days vs 13.5%, overall χ2 P < 0.001). Endometriosis was associated with a greater likelihood of poor to moderate work ability, after adjusting for age, body mass index, ethnicity, relationship status, student status, insecure housing, being a carer for another person, parity, ever use of assisted reproductive technologies, and depressed mood (odds ratio 1.90, 95%CI 1.40–2.58, P < 0.001).ConclusionsThis study provides new evidence that the negative impact of endometriosis on work attendance and work ability is not limited to women with prevalent symptoms and severe disease, but appears to encompass women across a broader spectrum of this condition in the community.

Published: April 2023

BackgroundThe rapidly rising prevalence of gestational diabetes mellitus (GDM) poses major challenges to the efficient, timely and sustainable provision of diabetes care.AimTo assess whether the implementation of a novel, digital model of care would provide improved efficiency without compromising clinical outcomes in a cohort of women with GDM.MethodsA digital model of care was developed, implemented and evaluated using a prospective pre‐post study design in 2020–21 at a quaternary centre. We introduced six culturally and linguistically tailored educational videos, home delivery of equipment and prescriptions, and a smartphone app‐to‐clinician portal for glycaemic review and management. Outcomes were prospectively recorded by an electronic medical record. Associations between model of care and maternal and neonatal characteristics and birth outcomes were examined for all women and separately by treatment received (diet, metformin, insulin).ResultsComparing pre‐implementation (n = 598) and post‐implementation (n = 337) groups, maternal (onset, mode of birth) and neonatal (birthweight, large for gestational age (LGA), nursery admission) clinical outcomes confirmed that the novel model of care was similar to standard, traditional care. Minor birthweight variation was noted when separated by treatment type (diet, metformin, insulin).ConclusionThis pragmatic service redesign demonstrates reassuring clinical outcomes in a culturally diverse GDM cohort. Despite the lack of randomisation, this intervention has potential generalisability for GDM care and important key learnings for service redesign in the digital era.
Physicochemical properties and structural changes of chicken breast meat subjected to radio frequency tempering combined with conventional thawing treatments

Published: April 2023

AbstractBeing able to thaw frozen meat in a reasonable time without impairing quality is crucial for industry and households. Radio frequency (RF) techniques have been used to defrost frozen foods. The influences of RF (50 kW, 27.12 MHz) tempering combined with water immersion (WI, 20°C) thawing (RFWI) or air convection (AC, 20°C) thawing (RFAC) on the physicochemical and structural changes of chicken breast meat were investigated, and the results were compared with those of the fresh meat (FM) and the meat samples subjected to WI and AC only. The thawing processes were terminated when the core temperatures of the samples reached 4°C. The results indicated that AC was the most time‐consuming technique, whereas RFWI required the least amount of time. The moisture losses, contents of the thiobarbituric acid–reactive substance, total volatile basic nitrogen, and total viable counts of the meat subjected to AC were higher. Relatively less changes in water‐holding capacity, coloration, oxidation, microstructure, protein solubility, and high sensorial acceptance were observed for RFWI and RFAC. This study demonstrated that the meat thawed using RFWI and RFAC was of satisfactory quality. Therefore, the RF techniques can be effective alternatives to the time‐consuming conventional thawing methods and benefit the meat industry.
