Estimation of full-scale performance of energy-saving devices using Boundary Layer Similarity model
Authors: Sadakata Katsuaki , Hino Takanori , Takagi Youhei 
Published: February 2024

AbstractThe recent global trend toward decarbonization is also occurring in the maritime industry and there is an urgent need to improve the fuel efficiency of ships. Various energy-saving devices (ESDs) are adopted for this purpose. However, because of the difference in the boundary layer thickness between full-scale and model-scale, it is difficult to estimate the actual performance of ESDs in a tank test. As a solution to overcome this difficulty, the Boundary Layer Similarity model (BLS model) is proposed in which only the stern part of the hull is extracted to shorten the model length and to make its boundary layer thickness equivalent to that of a full-scale ship. By using this BLS model, the performance of ESDs on a full-scale can be estimated in a model test. In the present paper, the applicability of the BLS model is investigated by CFD (Computational Fluid Dynamics) simulations of performance estimation of an energy-saving fin in different locations for a bulk carrier. It is found that the BLS model is capable of predicting the full-scale performance of the fins by the model-scale simulations. Moreover, the flow fields affected by the fins with the BLS model are similar to those of full-scale. It is expected that the use of the BLS model enables the prediction of the full-scale performance of ESDs in a model test.
Elderly-centered usability heuristics for augmented reality design and development

Published: February 2024

AbstractAugmented reality (AR) technology is making rapid progress and gaining high popularity, substantially due to the variety of new possibilities that it can offer to its users, including the elderly population. However, there is a lack of guidelines, recommendations, and testing techniques to make AR effective, efficient, and satisfying for its potential users. Usability heuristics are an effective tool that can help to ensure the usability of AR systems and can be used as a guide for the design and development process as well as a checklist for usability testing. However, general well-known usability heuristics do not consider specific aspects of AR, such as hardware limitations, privacy and safety issues, comfort of use, and the high importance of the user’s environment. General heuristics also do not always consider different user groups such as the elderly and people with disabilities. In this study, we developed a set of usability heuristics for AR systems for elderly users. The development process was inspired by the eight-step methodology by Quiñones et al. (Comput Stand Interfaces 59:109–129, 2018) and consisted of two main stages: gathering the heuristics from previous publications through an integrative literature review, and content analysis and validation of the collected heuristics through expert judgment (interviews with AR experts with industrial and academic backgrounds). The proposed final set of usability heuristics consists of six categories with a total of 55 heuristics that can be used by AR designers, developers, and usability testers to ensure the usability of AR systems for elderly users.
A collaborative decision support framework for sustainable cargo composition in container shipping services

Published: February 2024

AbstractThis paper proposes a decision support system (DSS) for optimizing cargo composition, and resulting stowage plan, in a containership of a shipping company in collaboration with en-route ports in the service. Due to considerable growth in transportation over years, an increasing number of containers are being handled by containerships, and ports consequently. Trade imbalances between regions and recent disruptions, such as LA/LB/Shanghai port congestion, blocking of Suez canal, drought in Panama canal, typhoons at ports, COVID-19 restrictions and the lack- and then over-supply of empty containers, have resulted in an accumulation of containers in exporting ports around the world. These factors have underscored the urgency of sustainability and circular economy within the shipping industry. The demand for container transportation is higher than the ship capacities in the recent times. In this regard, it is essential for shipping companies to generate a cargo composition plan for each service by selecting and transporting containers with relatively high financial returns, while offering a realistic stowage plan considering ship stability, capacity limitations and port operations. Ultimately, the selected containers should enable a ship stowage plan which keeps the ship seaworthy obeying complex stability considerations and minimizes the vessel stay at the ports, and port carbon emissions consequently, through efficient collaboration with en-route ports. This study provides a bi-level programming based DSS that selects the set of containers to be loaded at each port of service and generates a detailed stowage plan considering revenue, stowage efficiency and quay crane operational considerations. Numerical experiments indicate that the proposed DSS is capable of returning high-quality solutions within reasonable solution times for all ship sizes, cargo contents and shipping routes, supporting the principles of the circular economy in the maritime domain.
Short-Term Spatiotemporal Variability in Seawater Carbonate Chemistry at Two Contrasting Reef Locations in Bocas del Toro, Panama

AbstractThere is growing concern about the effects of ocean acidification (OA) on coral reefs, with many studies indicating decreasing calcium carbonate production and reef growth. However, to accurately predict how coral reefs will respond to OA, it is necessary to characterize natural carbonate chemistry conditions, including the spatiotemporal mean and variability and the physical and biogeochemical drivers across different environments. In this study, spatial and temporal physiochemical variability was characterized at two contrasting reef locations in Bocas del Toro, Panama, that differed in their benthic community composition, reef morphology, and exposure to open ocean conditions, using a combination of approaches including autonomous sensors and spatial surveys during November 2015. Mean and diurnal temporal variability in both physical and chemical seawater parameters were similar between sites and sampling depths, but with occasional differences in extreme values. The magnitude of spatial variability was different between the two sites, which reflected the cumulative effect from terrestrial runoff and benthic metabolism. Based on graphical vector analysis of TA–DIC data, reef metabolism was dominated by organic over inorganic carbon cycling at both sites, with net heterotrophy and net calcium carbonate dissolution dominating the majority of observations. The results also highlight the potentially strong influence of terrestrial freshwater runoff on surface seawater conditions, and the challenges associated with evaluating and characterizing this influence on benthic habitats. The Bocas del Toro reef is a unique system that deserves attention to better understand the mechanisms that allow corals and coral reefs to persist under increasingly challenging environmental conditions.
Investigating the role of tumour-to-skin proximity in predicting nodal metastasis in breast cancer
Authors: Sivakanthan Thiviya , Tanner J. , Mahata B. , Agrawal A. 
Published: February 2024

Abstract
Background
Understanding the factors influencing nodal status in breast cancer is vital for axillary staging, therapy, and patient survival. The nodal stage remains a crucial factor in prognostication indices. This study investigates the relationship between tumour-to-skin distance (in T1–T3 tumours where the skin is not clinically involved) and the risk of nodal metastasis.

Methods
We retrospectively reviewed data from 100 patients who underwent neoadjuvant chemotherapy (NACT). Besides patient demographics and tumour variables, a radiologist retrospectively reviewed pre-operative MRI to measure tumour-to-skin distance. R core packages were used for univariate (χ2 and T-Wilcoxon tests) and bivariate logistic regression statistical analysis.

Results
Of 95 analysable datasets, patients’ median age was 51 years (IQR: 42–61), 97% were symptomatic (rest screen detected), and the median tumour size was 43 mm (IQR, 26–52). On multivariate analysis, increasing invasive tumour size (p = 0.02), ER positivity (p = 0.007) and shorter tumour-to-skin distance (p = 0.05) correlated with nodal metastasis. HER2 was not included in multivariate analysis as there was no association with nodal status on univariate analysis. In node-positive tumours, as tumour size increased, the tumour-to-skin distance decreased (r = − 0.34, p = 0.026). In node-negative tumours, there was no correlation (r = + 0.18, p = 0.23).

Conclusion
This study shows that non-locally advanced cancers closer to the skin (and consequent proximity to subdermal lymphatics) are associated with a greater risk of nodal metastasis. Pre-operative identification of those more likely to be node positive may suggest the need for a second-look USS since a higher nodal stage may lead to a change in therapeutic strategies, such as upfront systemic therapy, node marking, and axillary clearance without the need to return to theatre following sentinel node biopsy.
Assessment of the acetylation process of wheat straw pulp as sustainable rheological modifier for non-polar fluids

Published: February 2024

AbstractThe main aim of this work was to study the role of the acetylation process of wheat straw pulp on its ability to rheologically modify two of the most important non-polar engineering fluid: bitumen and oil. Pulp was produced by a pilot-scale kraft pulping process from local wheat straw. Pulp was functionalized with acetic anhydride and sulfuric acid as a catalyst by modifying (temperature, pulp/acetic anhydride mass ratio, and reaction time. Further, chemical, morphological and thermal changes induced by the acetylation process were properly assessed. Acetylated wheat straw pulp dispersions in oil showed gel-like behaviour, with a mechanical spectrum characterized by higher values of the storage modulus (G′) and a minimum in the loss modulus (G″) at intermediate frequencies. The complex modulus (G*) for bitumen dispersions formulated with acetylated samples was up to 4 times higher than neat bitumen, and the phase angle (δ) indicated an enhancement in the elastic behavior parameters. The rheological response of these systems was associated with the microstructural network formed by pulp fibers and the balance between the physical and chemical changes of wheat straw fibers. According to the experimental results obtained, it can be concluded that acetylation is a relevant chemical treatment to modulate the rheological properties of wheat straw pulp dispersions in non-polar fluids, improving the compatibility between pulp fibers and these engineering fluids. Accordingly, this study provides valuable insights into the development of sustainable multiphasic materials (bitumen binders and semi-solid lubricants) for industrial applications.
Putting a New ‘Spin’ on Energy Information: Measuring the Impact of Reframing Energy Efficiency Information on Tumble Dryer Choices in a Multi-country Experiment
Authors: Ceolotto S. , Denny E. 
Published: February 2024

AbstractIt has been shown that consumers often underinvest in energy efficiency despite net benefits over the longer term. One possible explanation is that they do not properly understand energy information when provided in physical units, as in most energy labels. Prior studies have investigated the effect of reframing energy information into monetary units. Outcomes are mixed, and it is unclear whether this is due to the use of different products, methodologies or to studies being conducted in countries with different energy prices and labelling standards. This paper overcomes this ambiguity by testing the effect of providing monetary energy information using the same experiment in a multi-country setting. Results show that the intervention’s effectiveness varies considerably across countries. Moreover, they highlight the presence of within-country heterogeneities based on demographic characteristics, with monetary information being more effective for high-usage households but seemingly crowding out the motivation of those whose purchasing decisions depend on environmental considerations.

Published: February 2024

AbstractBlockchain is a newly emerging technology in the past decade that has significantly impacted various aspects. “Scientific popularization” among IT practitioners on this technology and its use cases become a pressing need. However, constructing an effective blockchain teaching approach for this purpose is a challenging task. A training framework consisting of constructivist and pragmatic approaches is proposed, aiming to provide IT practitioners with an effective Teaching and Learning (T &L) process about blockchain on both theory and application aspects. The outcomes of this study are to 1) propose an effective teaching methodology, 2) assess the effectiveness of constructivist and pragmatic approaches and 3) extract the elements facilitating blockchain T &L. Mixed quantitative and qualitative research methods were adopted, including questionnaires and knowledge quizzes. 1267 participants were involved in the training that implemented the proposed framework. Their performance and responses indicated that the framework is effective and flexible. The findings from this empirical research can serve as a reference for educators in blockchain to implement a systemic approach that facilitates the T &L process and improves the field of blockchain and education in the future.
SynFAGnet: A Fully Automated Generative Network for Realistic Fire Image Generation

Published: February 2024

AbstractThis paper proposes a fully automated generative network (“SynFAGnet”) for automatically creating a realistic-looking synthetic fire image. SynFAGnet is used as a data augmentation technique to create diverse data for training models, thereby solving problems related to real data acquisition and data imbalances. SynFAGnet comprises two main parts: an object-scene placement net (OSPNet) and a local–global context-based generative adversarial network (LGC-GAN). The OSPNet identifies suitable positions and scales for fires corresponding to the background scene. The LGC-GAN enhances the realistic appearance of synthetic fire images created by a given fire object-background scene pair by assembling effects such as halos and reflections in the surrounding area in the background scene. A comparative analysis shows that SynFAGnet achieves better outcomes than previous studies for both the Fréchet inception distance and learned perceptual image patch similarity evaluation metrics (values of 17.232 and 0.077, respectively). In addition, SynFAGnet is verified as a practically applicable data augmentation technique for training datasets, as it improves the detection and instance segmentation performance.
What motivates Chinese students to study in the UK? A fresh perspective through a ‘small-lens’
Authors: Consoli Sal 
Published: February 2024

AbstractChinese students represent a substantial portion of the UK university student population, with most of them being postgraduates. However, whilst the UK remains a top choice for Chinese students seeking to complete a higher degree programme, competition within the global Higher Education (HE) landscape is intensifying. Consequently, popular HE destinations such as the USA and the UK must now contend with growing academic markets in Australia and New Zealand (Marginson, 2006) as well as some non-English speaking countries which offer appealing university degrees through English-Medium-Instruction (EMI) (Mok, 2007). It is therefore salutary to ensure that Chinese students continue to find the UK appealing. This is vitally important both for the economy and the intellectual diversity and talents these students bring to UK HE institutions. This study thus revisits the core motives which drive Chinese students to UK universities. Significantly, unlike other investigations which have treated the topic of motivation rather marginally and through broad research scopes, this paper uses a ‘small-lens approach’ (Ushioda, 2016), which here is operationalised through the combination of practitioner research and narrative analysis. The study therefore focuses on a small group (N = 16) of Chinese students to unpack the nuances of meaning which characterise their initial motivation to study in Britain.
Disease features and management of cardiomyopathies in women

Published: February 2024

AbstractOver the last years, there has been a growing interest in the clinical manifestations and outcomes of cardiomyopathies in women. Peripartum cardiomyopathy is the only women-specific cardiomyopathy. In cardiomyopathies with X-linked transmission, women are not simply healthy carriers of the disorder, but can show a wide spectrum of clinical manifestations ranging from mild to severe manifestations because of heterogeneous patterns of X-chromosome inactivation. In mitochondrial disorders with a matrilinear transmission, cardiomyopathy is part of a systemic disorder affecting both men and women. Even some inherited cardiomyopathies with autosomal transmission display phenotypic and prognostic differences between men and women. Notably, female hormones seem to exert a protective role in hypertrophic cardiomyopathy (HCM) and variant transthyretin amyloidosis until the menopausal period. Women with cardiomyopathies holding high-risk features should be referred to a third-level center and evaluated on an individual basis. Cardiomyopathies can have a detrimental impact on pregnancy and childbirth because of the associated hemodynamic derangements. Genetic counselling and a tailored cardiological evaluation are essential to evaluate the likelihood of transmitting the disease to the children and the possibility of a prenatal or early post-natal diagnosis, as well as to estimate the risk associated with pregnancy and delivery, and the optimal management strategies.
The consequences of the 2017 US international tax reform: a survey of the evidence
Authors: Dharmapala Dhammika 
Published: February 2024

AbstractThe 2017 US tax legislation—widely referred to as the Tax Cut and Jobs Act (TCJA)—fundamentally transformed the US system of international taxation. It ostensibly ended worldwide taxation but introduced, for instance, a new tax on “Global Intangible Low-Taxed Income”. This paper surveys the emerging empirical literature on the impact of the TCJA’s international provisions. It documents five robust findings in this empirical literature. First, the TCJA led to a general decline in US MNCs’ foreign acquisitions. Second, the TCJA increased US MNCs’ investment in routine foreign tangible assets. Third, the reform did not lead to any change in profit shifting by US MNCs beyond the magnitude that would be expected based on the TCJA’s tax rate reduction. Fourth, The TCJA appears to have reduced the market value of US MNCs relative to domestic US firms. Fifth, the TCJA does not appear to have had any detectable impact on domestic US investment and wages (although there are some contrary results for capital expenditures). The welfare implications of these findings depend crucially on whether US MNCs’ are viewed as having engaged in too much or too little foreign activity prior to the TCJA. This depends on the choice of theoretical framework and the relevant normative benchmark, and cannot readily be resolved empirically.
Optimal Transport and Model Predictive Control-based Simultaneous Task Assignment and Trajectory Planning for Unmanned System Swarm
Authors: Wu Xiwei , Xiao Bing , Cao Lu , Huang Haibin 
Published: February 2024

AbstractThis paper presents a simultaneous task assignment and trajectory planning method for unmanned system swarm by using optimal transport and model predictive control (OT-MPC). Unlike the conventional hierarchical assignment and planning, the proposed approach addresses both the task assignment and trajectory planning subproblems concurrently. To be specific, a unified cost function is designed to solve task assignment and trajectory planning problem. Moreover, the multi-tasks are assigned by using optimal transport, which establishes an optimal mapping between tasks and unmanned system vehicles based on transportation cost. The trajectory planning is achieved by using model predictive control, which generates high-quality navigation trajectories considering obstacle avoidance. Finally, the proposed method is applied to the unmanned surface vehicles swarm. Numerical simulations and experiments were conducted to validate the effectiveness of the proposed method.
A Dynamic View of the Challenge-Hindrance Stressor Framework: a Meta-Analysis of Daily Diary Studies

Published: February 2024

AbstractAre some daily job stressors good for employees? The challenge-hindrance stressor framework (CHSF) attempts to shed light on this question by categorizing stressors according to their ability to facilitate (challenge stressors) or inhibit (hindrance stressors) growth and achievement. According to the CHSF, challenge stressors should be associated with increased performance, but also with increased strain which subsequently hurts performance. Conversely, hindrance stressors should be associated with reduced performance both directly and indirectly via strain. Prior meta-analytic investigations have focused on more stable job stressors (using cross-sectional or longitudinal primary studies), and found contradicting resulted in support of the CHSF predictions. In the current meta-analysis, we tested the validity of the CHSF using a more dynamic view of stressors, by applying it to short-term, daily experiences of stressors, strains, and performance outcomes. Results from 78 unique samples indicated that at the within-person level, hindrance stressors have both a direct and an indirect (via strain) short-term effect on performance. Challenge stressors have a positive direct effect on performance but a negative indirect effect via strain. Furthermore, we examined two performance indicators separately: task performance and organizational citizenship behaviors (OCB). The results revealed that challenge stressors have a stronger positive association with OCB than with task performance. Hindrance stressors exhibited the opposite pattern, a stronger negative association with task performance than with OCB. The results of this study suggest that all daily stressors result in strain, which negatively relates to performance, though challenge stressors also have some positive effects on daily performance.
