Authors: Wang Shuliu , Liu Qianqian , Wang Jin , Chen Nana , Chen JunHang , Song Jialiang , Zhang Xin , Xiao Kui 
Published: February 2024

Purpose
This study aims to investigate the role of aluminium (Al) in marine environment and the corrosion mechanism of galvalume coatings by conducting accelerated experiments and data analysis.

Design/methodology/approach
Samples were subjected to accelerated corrosion for 136 days via salt spray tests to simulate the natural conditions of marine environment and consequently accelerate the experiments. Subsequently, the samples were examined using various test methods, such as EDS, scanning electron microscopy (SEM), X-ray diffraction (XRD) and electrochemical impedance spectroscopy (EIS), and the obtained data were analysed.

Findings
Galvalume coatings comprised interdigitated zinc (Zn)-rich and dendritic Al-rich phases. Corrosion was observed to begin with a Zn-rich phase. The primary components of the corrosion product film were Al2O3 and Zn5(OH)8Cl2·H2O. It was confirmed that the role of Al was to form a dense protective film, thereby successfully blocking the entry of corrosive media and protecting the iron substrate.

Originality/value
This study provides a clearer understanding of the corrosion mechanism and kinetics of galvalume coatings in a simulated marine environment. In addition, the role of Al, which is rarely mentioned in the literature, was investigated.

Authors: Scheepers Carla , Moore Amy Fisher 
Published: February 2024

Learning outcomes
After completion of the case study, the students will be able to identify and discuss competition using Porter’s five forces, analyse and understand the enablers and challenges that impacted Rocky Brands’ growth and recommend a solution in relation to Rocky Brands’ growth strategy.

Case overview/synopsis
This case study investigates Rocky Brands, a South African manufacturer and distributor of cleaning products in the retail market. The case was set in November 2022 and highlights the important events ranging from the company’s founding in 2011 up until 2022. This case aims to study strategy in the South African fast moving consumer goods industry. At the time of writing the case study, Rocky Brands was operating across South Africa, with their main manufacturing warehouse in Johannesburg and a subsidiary manufacturing warehouse in Durban. They were changing the Durban warehouse to a distribution warehouse, as they planned to manufacture primarily from a bigger warehouse in Johannesburg. Rishav Juglall, the main protagonist, is the founder and managing director of Rocky Brands. Rocky Brands imports and redistributes several of the brands that the company sells, including Weiman’s, Wright’s and Goo Gone. They also manufacture their own line of products in South Africa under the Oakmont brand. Juglall acknowledges that their sales and revenue have grown yearly, but they have recently saturated the market and reached a plateau. Juglall needs to determine whether he should diversify into Africa, expand his product range or enter the market for private label cleaning products.

Complexity academic level
The case study’s primary focus is on strategy in an emerging market. This case study is suited to undergraduate students studying Porter’s five competitive forces, SWOT analysis (see teaching note exhibit) or the Ansoff matrix in the fields of strategy, marketing or macroeconomics. This case study can be taught in courses such as decision-making, environment of business, leadership or strategic implementation. The case study will teach students how to apply the frameworks to a business and assist students in determining which option is best for the business.

Understanding the key drivers in using mobile payment (M-Payment) among Generation Z travellers
Authors: Hanafiah Mohd Hafiz , Asyraff Muhammad Aliff , Ismail Mohd Noor Ismawi , Sjukriana Juke 
Published: February 2024

Purpose
The purpose of this study is twofold. The first objective is to identify the factors that affect Gen Z tourists' M-payment behaviour. Next, this study investigates the inter-relationship between Gen Z tourist’s perception of M-payment benefits, adoption behaviour, usage risk and future usage intention.

Design/methodology/approach
The sample comprised Malaysian Gen Z individuals (n = 326) who had experience using M-payment methods while travelling outbound. Given the complex nature of the model and the goal to predict and explain relationships within Gen Z's M-payment usage, partial-least square-structural equation modelling was used to assess the study framework and test the proposed relationships.

Findings
This study reveals significant influences on Gen Z tourists' behavioural intentions towards M-payment usage. Perceived benefits, performance expectancy, social influence and perceived trust positively impact behavioural intentions, while effort expectancy exhibits no significant effect. Furthermore, perceived trust is strongly influenced by perceived security, which also positively influences behavioural intentions. A mediated relationship is evident as trust mediating the effect of perceived security on behavioural intentions.

Research limitations/implications
This study’s findings contribute to understanding the intricate relationships influencing Gen Z's M-payment behaviour and underscore trust's pivotal role in mediating the security–behavioural intention relationship.

Originality/value
This study is among the first to consider Mental Accounting Theory and the Unified Theory of Acceptance and Use of Technology as crucial underpinning theories in comprehending the intricate relationships that influence Gen Z travellers' perceptions and behaviours concerning M-payment systems.
Preparation of red jujube powder with high content of Amadori compounds and higher antioxidant activity by controlling the Maillard reaction

Published: February 2024

AbstractAmadori compounds (ACs) are stable compounds produced in the early stage of the Maillard reaction (MR) with health benefits such as immunomodulatory, antithrombosis, and tumor‐preventive effects. Jujube is a medicinal and edible fruit in China. It is rich in free amino acids and reducing sugar, but traditionally, little attention was paid to the formation of ACs when jujube was processed, neither the influence of ACs on health effects. In this paper, we aimed to increase ACs through controlling the MR during different heating processes of jujube powder with adjusted water content and find the most effective AC that contributed to the antioxidant effects of jujube powder. The optimal dry‐heating conditions to produce ACs were as follows: The water activity was 0.294, the heating temperature was 90°C, and the time was 120 min. After processing, the ACs content of jujube powder was 18.55 ± 0.19 mg/g dry weight (DW), which was more than 100 times of those in the unheated jujube powder (0.153 ± 0.003 mg/g DW). Besides, the antioxidant activity of jujube powder after dry‐heating process was higher than that of unheated one. As the most abundant AC in the dry‐heated jujube powder (12.90 ± 0.75 mg/g DW), N‐(1‐deoxy‐d‐fructose‐1‐yl) proline (Fru‐Pro) showed the highest antioxidant activity (62% of equivalent l‐ascorbic acid) among 12 ACs in ferric reducing antioxidant power assay. This result provided a method to produce jujube product with high content of ACs and confirmed the positive contribution of Fru‐Pro to the antioxidant activity of the jujube powder.

Published: February 2024

AbstractObjectiveLittle is known about the normative courses of pregnancy‐related anxiety throughout pregnancy and their antecedents. We examined in a large scale pregnancy cohort which potentially distinct trajectories of pregnancy‐related anxiety across pregnancy can be identified, and which factors predict these trajectories.MethodsA general sample of pregnant women (n = 2928) from the FinnBrain Birth Cohort participated in this study. Several questionnaires were filled in at 14, 24, and 34 weeks of gestation, including the pregnancy‐related anxiety questionnaire‐revised as main outcome. Latent Growth Mixture Modeling was applied to identify the trajectories of pregnancy‐related anxiety across pregnancy, and t‐tests and chi‐quare tests were conducted to find antecedents of these trajectories.ResultsTwo distinct trajectories were identified: (1) a low symptoms group, N = 2594 (88.6%), with lower and slightly increasing levels of pregnancy‐related anxiety (2) a moderately‐high symptoms group, N = 334 (11.4%) reported higher and slightly decreasing levels of anxiety. Correlates of the moderately‐high anxious group included a lower monthly income, drinking alcohol or smoking in early pregnancy, more daily hassles and less joy, more early life adversities, younger age, primiparity, single parenthood, using depression medication, and having higher scores on depression and general anxiety.ConclusionsAlthough the majority of pregnant women fall within a low risk trajectory of pregnancy‐related anxiety, another group with consistently higher levels of pregnancy anxiety throughout pregnancy may need more clinical attention, as their high pregnancy‐related anxiety scores may indicate a risk profile that includes a variety of general and more pregnancy‐specific risk factors, which together can negatively affect fetal and infant development and behavior.
Comparison of craniometric measurements of New Zealand rabbit (Oryctolagus cuniculus L.) using three‐dimensional scanner with digital calliper measurements: A methodological study

Published: February 2024

AbstractAs technology has developed in recent years, the use of three‐dimensional (3D) scanners and printers has become widespread in the medical field. However, since this field is new, all kinds of methodological and experimental related studies gain importance. This study aimed to identify the differences between the calliper measurements by determining the craniometric data on the models constructed by scanning the crania of New Zealand Rabbits (Oryctolagus cuniculus L.), preferred as experimental animals, with a three‐dimensional scanner. Therefore, a total of 12 New Zealand rabbits including 6 females and 6 males were used. After the crania that comprised the study material were macerated, they were subjected to 3D scanning. After the scanning process was completed, they were craniometrically measured both on the scanned models and by using a digital calliper. Analysis of the craniometric data of the 3D scanner showed that there was a difference between sexes at the level of p < 0.05 in widest length between the external acoustic meatus (WLBEAM), skull width and Foramen magnum height (FMH) parameters and cranial index data, and at the level of p < 0.001 in the largest nasal width (LNW) parameter. A statistical difference was found between sexes in frontal length, WLBEAM, LNW and FMH parameters and cranial index values in craniometric data collected with the digital calliper (p < 0.05). Consequently, the data collected in this study were found to be close to each other in both methods, suggesting that the 3D scanner may be used in morphometric studies.

SummaryBackgroundReports of DILI due to herbal and dietary supplements have been increasing over time.AimsTo characterise clinical, laboratory and histopathological phenotypes and outcomes of drug‐induced liver injury (DILI) due to anabolic‐androgenic steroids (AAS), selective androgen receptor modulators (SARMs), and bodybuilding supplements (BBS) in Australia.MethodsRetrospective case series. Patients presented to nine Australian tertiary hospitals, 2017–2023. DILI was defined biochemically and patients were included if their treating physician attributed DILI to preceding use of AAS, SARMs or BBS. Primary endpoint was time to normalisation of liver biochemistry. Secondary endpoints were hospitalisation for investigation or management of DILI, death attributable to liver injury, and liver transplantation.ResultsTwenty‐three cases of DILI were identified, involving 40 drugs: 18 AAS, 14 SARMs and eight BBS. Patients were predominantly male (22/23), with median age 30 years (IQR 26–42). Most were symptomatic (21/23). Median latency of onset was 58 days (IQR 28–112 days) from drug commencement. Most patients (17/23) were admitted to hospital. Based on updated Roussel Uclaf Causality Assessment Method, DILI was possible in 17/23, probable in 2/23 and unlikely in 4/23. Median time to normalisation of liver biochemistry was 175 days (IQR 70–292 days) from presentation. Three (3/23) were treated with corticosteroids, 14/23 were treated for itch, and one (1/23) underwent liver transplantation. There were no deaths.ConclusionsThe prognosis of DILI from AAS, SARMs and BBS is good although liver transplantation may rarely be required. A detailed drug history is important in uncovering DILI due to these supplements.

Published: February 2024

AbstractAimsThe objective of this meta‐analysis was to determine whether maternal exposure to folate antagonists is associated with increased rates of congenital heart disease in offspring.MethodsA comprehensive search for articles in the MEDLINE (PubMed) and EMBASE databases published up to 21 August 2023 was performed. The search strategy was not limited by study design but only for articles in the English language.ResultsAnalysis of 6 cohort studies and 5 cross‐sectional studies, published between 1976 and 2020, showed significant increase in rate of congenital heart disease (odds ratio 1.55, 95% confidence interval, 1.28–1.87) when exposed to folate antagonists compared with the control. Further subgroup analysis showed the increased rate for exposure to both dihydrofolate reductase inhibitors and antiepileptic drugs separately. No differences were observed when analyses were stratified by timing of study.ConclusionAdministration of folate antagonists within the 12‐week period preceding conception and throughout the second and third months of gestation exhibited a statistically significant elevation in the susceptibility to congenital heart diseases. Notably, the protective effect of folic acid supplementation was reported in cases of congenital heart disease linked to dihydrofolate reductase inhibitors but not that associated with antiepileptic drugs.
Sensitivity of modelled passive margin stratigraphy to variations in sea level, sediment supply and subsidence
Authors: Schmelz William J. , Miller Kenneth G. , Mountain Gregory S. , Steckler Michael S. , Browning James V. 
Published: February 2024

AbstractWe produced a 10 Myr synthetic stratigraphic section using a forward stratigraphic model that generates marine deltaic stratigraphy over geological timescales. We recursively fit the model using a Bayesian inversion algorithm to test: (1) if it could be accurately reconstructed; (2) if the parameters used to create it could be recovered; and (3) the sensitivity of the model output to given model parameters and the attendant physical processes. The original synthetic stratigraphic section was produced with cyclical sea‐level variations of 40 and 30 m with 2.4 and 10 Myr periods respectively. Sediment was also supplied cyclically, in 2.4 and 10 Myr cycles with amplitudes of 30 and 80 tons/100 kyr, respectively, varying from a mean of 232 tons/100 kyr. Parameter values were sampled to fit the model using a Markov chain Monte Carlo algorithm, resulting in a ±5 m (1σ) variation between the experimental output and the original. Sea level varied by ±7 m (1σ) within the posterior distribution of parameters. As a result, both the 10 Myr and 2.4 Myr sea‐level cycles could be extracted from the original output. The variation in sediment supply was approximately ±38 tons/100 kyr (1σ) and, as a result, only the larger long‐term supply variations could be accurately recovered in refitting the model. The variation in thermal, flexural and total subsidence across those parameter sets is less than ±10 m (1σ). The original section experienced 150 m of total subsidence at the depocentre. Our results demonstrate the distinct and interpretable imprint of sea level and subsidence on continental margin stratigraphy can be quantified. Moreover, we conclude that sea‐level change produces a defined effect on the geometries of stratigraphic architecture, and that techniques applied for the purpose of delineating sea‐level variation from continental margin strata have a well‐founded conceptual basis.
Parental evaluations of neighbourhood green and play spaces and children's mental health
Authors: LeClair James A. 
Published: February 2024

AbstractGeographical analyses of mental health problems have been undertaken since at least the 1930s, with such work preoccupied primarily with ecological correlations between the prevalence of mental illness and small‐area variations in socioeconomic status. More recently, parks and other green spaces have emerged as place characteristics of interest for their possible public health significance, as they relate to both physical and mental health, including the psychosocial well‐being of children. In this paper, I consider the relationships between parent‐reported adequacy of neighbourhood play and green spaces and children's psychosocial well‐being, as measured by parental assessments of their children's mental health, as well as scores on the Strengths and Difficulties Questionnaire, a psychometric instrument that is demonstrably effective in the identification of behavioural problems in children and adolescents. The findings reported here are consistent with the notion that access to natural spaces and opportunities to play are associated with a reduced risk for mental health problems. Specifically, risk reduction is suggested for overall behavioural functioning, as well as specific behavioural difficulties related to problems in peer relationships, hyperactivity, and emotional problems, as well as parent‐assessed child mental health status.
Camera trap sampling protocols for open landscapes: The value of time‐lapse imagery
Authors: Leorna Scott , Brinkman Todd 
Published: February 2024

AbstractCamera traps (CT) have been used to study a wide diversity of wildlife around the world. However, despite their widespread use, standardized protocols are lacking, potentially leading to reduced efficiency and inhibiting study comparisons, generalizability, and repeatability. While there are general guidelines and considerations researchers should be aware of when designing a CT survey, studies have shown the vital importance of selecting sampling schemes and camera settings tailored to specific characteristics of the wildlife system of interest. For many species and regions, optimal sampling protocols have not been thoroughly evaluated, especially in vast open landscapes. We used CT data on barren‐ground caribou (Rangifer tarandus) in the open landscape of arctic Alaska as a case study to evaluate and quantify the influence of camera trigger type (i.e., motion detection vs. time‐lapse) and time‐lapse interval on data generation to inform sampling protocols for future CT research in this system or others like it. Comparing camera trigger types, we found 5 min interval time‐lapse generated seven‐times more images containing caribou compared to motion detection. However, the detection rate of motion detection was over 11‐times greater than time‐lapse resulting in more efficient data collection with respect to camera battery life, data storage, and data processing time. Exploring the effect of time‐lapse interval length, we found detections were highly sensitive to interval length with a 30 min interval producing 33.7% fewer images containing caribou and identifying 22.2% fewer trap days containing caribou compared to a 5 min interval. Our results provide insight into effective CT sampling protocols for open landscapes and highlight the importance of critically evaluating and selecting camera settings that account for characteristics of the study system to ensure adequate data is generated efficiently to address study objectives.

AbstractBackgroundDesensitization is one of the strategies to reduce antibodies and facilitate heart transplantation in highly sensitized patients. We describe our center's desensitization experience with combination of plasma cell (PC) depletion therapy (with proteasome inhibitor or daratumumab) and costimulation blockade (with belatacept).MethodsWe reviewed five highly sensitized patients who underwent desensitization therapy with plasma cell depletion and costimulation blockade. We evaluated the response to therapy by measuring the changes in cPRA, average MFI, and number of positive beads > 5000MFI.ResultsFive patients, mean age of 56 (37‐66) years with average cPRA of 98% at 5000 MFI underwent desensitization therapy. After desensitization, mean cPRA decreased from 98% to 70% (p = .09), average number of beads > 5000 MFI decreased from 59 to 37 (p = .15), and average MFI of beads > 5000 MFI decreased from 16713 to 13074 (p = .26).ConclusionCombined PC depletion and CoB could be a reasonable strategy for sustained reduction in antibodies in highly sensitized patients being listed for heart transplantation.
