Metaethics as conceptual engineering
Authors: Skarsaune Knut Olav 
Published: April 2023

AbstractOn the traditional approach to metaethics, theories are expected to be faithful to ordinary normative discourse—or at worst (if we think the ordinary discourse is metaphysically unsound) to deviate from it as little as possible. This paper develops an alternative, “conceptual engineering” approach to metaethical enquiry, which is not in this way restricted by our present discourse. On this approach, we will seek to understand the psychology, semantics, metaphysics and epistemology, not just of our present concepts, but also of other possible normative concepts. The ultimate point of the enquiry is to choose between the available alternatives: to decide what kinds of normative concepts to use, going forward. The paper aims to make this suggestion precise, in a way that (a) answers worries about circularity, (b) answers worries about “changing the subject”, (c) retains metaethics as a truth‐seeking enquiry, and (d) leads to an independently plausible methodology.
Switching to profitable outside options under supplier encroachment
Authors: Liang Liang , Chen Jingxian , Yao Dong‐qing 
Published: April 2023

In practice, manufacturers may encroach on retail markets through a variety of methods, one being through the use of an online channel direct to the consumers, called encroachment. Current research typically assumes that downstream retailers retain procurement from the encroaching supplier. In reality, however, retailers may have the option of switching suppliers after encroachment. By considering a supply chain consisting of one manufacturer and one retailer with outside options, this paper analyzes the effects of the option of switching suppliers on the supply chain players' strategic interactions under the threat of supplier encroachment. We consider that the manufacturer makes encroachment decision preceding the retailer's switch decision. We capture various outcomes of the encroachment and switch decisions by using a classic encroachment model with quantity decisions (Cournot model). Specifically, we identify two effects of the outside option on the strategic encroachment decision. The first, the deterrence effect, means that the manufacturer's encroachment is deterred by the threat of switching supplies altogether; while the second, the permissive effect, indicates that the retailer intends to switch to the alternative source after the encroachment. Interestingly, we show that the encroachment could improve the total profit of the incumbent manufacturer and the retailer even when the retailer's switch has occurred. In this case, however, the manufacturer profits while the retailer is hurt by the encroachment and the switch. Finally, we also investigate several extended cases to demonstrate the robustness of our findings.
Compliance in crisis: Concern, trust and distrustful complacency in the COVID‐19 pandemic

Published: April 2023

AbstractTwo studies tested a distrustful complacency hypothesis, according to which either concern or political trust would be enough to sustain law‐abiding attitudes and compliance with health‐protective policies during the COVID‐19 pandemic; but the absence of both concern and trust would result in markedly lower support and compliance. Study 1 supported this hypothesis with NatCen nationally representative sample of Great Britain (N = 2413; weighted regression analyses), focussing on law‐abiding attitudes. Study 2 (preregistered) replicated these findings with a representative sample (N = 1523) investigating support for COVID‐19 policies and compliant behaviour. Participants who were less concerned about the consequences of the pandemic (for themselves and for others) and simultaneously less trustful of the government expressed weaker law‐abiding attitudes and reported less compliance with COVID‐19 restrictions. These findings have implications for policy and public health strategies in time of crisis.
Expanding access to STEM pathways: Professional learning for high school counselors

Published: April 2023

AbstractThis study is situated within a large‐scale national high school level engineering education initiative that aims to “demystify” engineering for high school students, teachers, and counselors through an all‐inclusive high school level engineering course. Counselors participated in a series of PD activities centered on the following components: (1) design and development of a new engineering course open to all high school students, (2) teacher and counselor PD, and (3) a learning community of teachers, counselors, engineering educators, and practicing engineers. We utilized an exploratory qualitative research design to understand counselors’ perceptions and experiences. Through their own hands‐on experiences, counselors had concrete examples to share with students about engineering as a field to consider for postsecondary education and careers. Further, through a broadened understanding of the skills needed to excel in engineering, counselors expressed that they would work with all students to recommend them towards engineering, rather than just the “math and science” students. Through this study, we identified an important gap in the engineering pipeline: high school guidance counselors. In order to broaden participation in engineering, we must first expand the knowledge of those people working closely with high school students on postsecondary plans.

Published: April 2023

AbstractSkin, as an exposed tissue, often suffers damage after exposure to radiotherapy and accidental events, which may lead to the formation of chronic refractory wounds. However, effective treatment options are usually limited for severe radiation‐induced skin injury (RSI). Platelet‐rich plasma (PRP) has been identified to promote wound healing, but whether a new generation of blood‐derived biomaterial, injectable platelet‐rich fibrin (i‐PRF), is effective in repairing RSI remains unclear. In this study, blood was drawn from humans and Sprague–Dawley rats to prepare PRP and i‐PRF, and the regenerative functions of PRP and i‐PRF were investigated by exposing the dorsal skin of SD rats to local radiation (45 Gy) and exposing HDF‐α cells and human umbilical vein endothelial cells (HUVECs) cells to X‐rays (10 Gy). The healing effect of i‐PRF on RSI was analysed by tube formation assay, cell migration and apoptosis assays, ROS assay, wound healing assay, histological characterisation and immunostaining. The results showed that exposure to high doses of radiation reduced cell viability, increased ROS levels and induced cell apoptosis, thereby causing dorsal trauma of rats. However, both PRP and i‐PRF could resisted RSI, and they were capable of reducing inflammation and promoting angiogenesis and vascular regeneration. i‐PRF has a higher concentration of platelets and platelet‐derived growth factors, which has a more convenient preparation method and better repair effect and possesses a good application prospect for the repair of RSI.
Preclinical assessment of novel longer‐duration wear negative pressure wound therapy dressing in a porcine model
Authors: Allen Diwi , Robinson Timothy , Schmidt Marisa , Kieswetter Kristine 
Published: April 2023

AbstractWhile reticulated open cell foam (ROCF) is a well‐established dressing for negative pressure wound therapy (NPWT), there is the known potential for granulation tissue ingrowth if left in place for longer than 72 h. This may cause wound bed disruption, bleeding, and pain upon dressing removal. In addition, any retained foam fragments may elicit an adverse tissue reaction. A novel, easy to use dressing designed to utilise the advantages of ROCF while addressing its challenges has recently been created. This 7 day study investigated the utility of a novel NPWT dressing under longer‐duration wear circumstances while assessing the prevalence of tissue ingrowth and ease of dressing removal in full‐thickness excisional wounds utilising a porcine model. Histopathology and morphometry evaluations indicated thicker granulation tissue with, depending on the parameters assessed, either comparable or better tissue quality for wounds treated with the novel dressing. Greater re‐epithelialization levels were also evident compared with ROCF. Three‐dimensional imaging analysis indicated faster wound fill with a corresponding decrease in wound area with the novel dressing. Furthermore, tissue ingrowth was limited to only ROCF‐treated wounds, which was not unexpected in this longer‐duration wear study. The force required to remove the novel dressing was considerably lower compared with ROCF, correlating to the tissue ingrowth results. Results of this study illustrate that the novel dressing provided more favourable wound healing results compared with traditional ROCF. In addition, reduction in the risk of tissue ingrowth and low dressing peel force may allow it to be used as a longer‐wear dressing.
ANALYSIS OF GRAVITY ON ALTITUDE CHANGES IN GRAVITY MICRO DATA USING POLYNOMIAL EQUATION APPROACH (CASE STUDIES OF MERAPI AND KELUD VOLCANOES)
Authors: Setiawan Ari , Huda Immanatul , Lewerissa Richard 
Published: April 2023

Analysis of gravity changes to altitude changes from gravity measurements at Merapi Volcano and Kelud Volcano was carried out to determine the characteristics of the two mountains based on the gravity method. Merapi Volcano and Kelud Volcano are two very active mountains in Indonesia and have different physiography, especially at the top of Kelud there is a crater filled with water. Repeated gravity surveys will be useful for studying deformation in volcanoes and providing information about changes in subsurface mass. The gravity data on Merapi Volcano is secondary data from BPPTKG (Research and Development Center for Geological Disaster Technology), and data on Kelud Volcano is obtained from the 2019 data collection survey. Volcanic monitoring using the gravity method is carried out by observing changes in gravity with changes in altitude to study deformation in the volcano and providing information about changes in subsurface mass using a polynomial equation approach of to . The findings indicate that there was little variation in the gravity anomaly within Merapi Volcano between 2018 and 2019. The highest coefficient of determination, at 96%, was observed in the gravity anomaly data from inside the Kelud Volcano in 2019, after applying Bouguer corrections in the form of spherical effects. Additionally, the coefficients of the second and third order polynomials of the Merapi Volcano data had opposite signs to those of Kelud Volcano, suggesting that the internal source of the gravity anomaly within Merapi Volcano is distinct from that within Kelud Volcano.
The asymptotics of the holomorphic analytic torsion forms
Authors: Puchol Martin 
Published: April 2023

AbstractThe purpose of this paper is to give an asymptotic formula for the holomorphic analytic torsion forms of a fibration associated with a sequence of direct images of increasing powers of a line bundle on a bigger manifold. To handle the growing dimension of the direct images, we use the theory of Toeplitz operators. This is the family versions of the results of Bimsut and Vasserot on the asymptotics of the holomorphic torsion, as well an extension for more general bundles.

Published: April 2023

Abstract
This work tackles practical issues that arise when using a tendon-driven robotic manipulator (TDRM) with a long, flexible, passive proximal section in medical applications. Tendon-driven devices are preferred in medicine for their improved outcomes via minimally invasive procedures, but TDRMs come with unique challenges such as sterilization and reuse, simultaneous control of tendons, hysteresis in the tendon-sheath mechanism, and unmodeled effects of the proximal section shape. A separable TDRM that overcomes difficulties in actuation and sterilization is introduced, in which the body containing the electronics is reusable and the remainder is disposable. An open-loop redundant controller that resolves the redundancy in the kinematics is developed. Simple linear hysteresis compensation and re-tension compensation based on the physical properties of the device are proposed. The controller and compensation methods are evaluated on a testbed for a straight proximal section, a curved proximal section at various static angles, and a proximal section, which dynamically changes angles, and overall, distal tip error was reduced.
Numerical Investigation of Cross-Flow Water Cooling Towers
Authors: Can Omer F. , Alabbas Muhammed 
Published: April 2023

Abstract
In this study, thermal performance of the forced cross-flow water cooling tower is numerically investigated by using the commercial computational fluid dynamics software ansys-cfx. The temperature variation between inlet and outlet of the water, namely, process water temperature, is the main extracted result of simulations. Additionally, the cooling range (CR) that is the difference between inlet water temperature and outlet water temperature is the second representative result of the analysis. The effect of air velocity (Va), water droplet diameter (dw), and water temperature at the inlet of tower (Tw) are the variables that are considered to be the effective design parameters on the process temperature of the water. The process water temperature decreases, but the cooling range increases when the air velocity increases. When the inlet water temperature increases, the process water temperature and the cooling range also increase. On the other hand, the process water temperature decreases with the decreasing diameter of water droplets.

Published: April 2023

Abstract
The development of prediction models for solar thermal systems has been a research interest for many years. The present study focuses on developing a prediction model for solar box cookers (SBCs) through computational and machine learning (ML) approaches. The prime objective is to forecast cooking load temperatures of SBC through ML techniques such as random forest (RF), k-nearest neighbor (k-NN), linear regression (LR), and decision tree (DT). ML is a commonly used form of artificial intelligence, and it continues to be popular and attractive as it finds new applications every day. A numerical model based on thermal balance is used to generate the dataset for the ML algorithm considering different locations across the world. Experiments on the SBC in Indian weather conditions are conducted from January through March 2022 to validate the numerical model. The temperatures for different components obtained through numerical modeling agree with experimental values with less than 7% maximum error. Although all the developed models can predict the temperature of cooking load, the RF model outperformed the other models. The root-mean-square error (RMSE), determination coefficient (R2), mean absolute error (MAE), and mean square error (MSE) for the RF model are 2.14 (°C), 0.992, 1.45 (°C), and 4.58 (°C), respectively. The regression coefficients indicate that the RF model can accurately predict the thermal parameters of SBCs with great precision. This study will inspire researchers to explore the possibilities of ML prediction models for solar thermal conversion applications.

Published: April 2023

Abstract
As the main energy consumption part of the central air-conditioning system, the energy saving of the chilled water system is particularly important. In this paper, an improved fruit fly optimization algorithm (IFOA) is used to optimize the operating parameters of the chilled water system to reduce the energy consumption of the chilled water system. In IFOA, the 3-D position coordinate is introduced to expand the search space of the algorithm, the variable-step strategy balances the global search ability and local search ability of the algorithm and helps a single fruit fly jump out of the local optimization through chaos mapping. In order to verify the optimization effect of IFOA on the chilled water system, the energy consumption model of the chilled water system is established. With the lowest total energy consumption of the system as the goal, the operating parameters such as the chilled water supply temperature and the speed ratio of the chilled water pump are optimized. The simulation results show that the energy-saving optimization method of a central air-conditioning chilled water system based on IFOA can make the average energy-saving rate of the system reach 7.9%. Compared with other optimization algorithms, the method has a better energy-saving effect and is more stable.

Published: April 2023

Sports coaching is a volatile and stressful career that may impact professionals’ well-being. Thus, variables that can promote coaches’ job satisfaction need to be investigated. Based on the hypotheses of potential effects of passion for work (e.g., subjects’ inclination for an activity, which becomes integrated into the person’s identity) on flow experience (e.g., positive and transient state that can promote total absorption, enjoyment, and intrinsic motivation) and job satisfaction (e.g., state of positive emotions, resulting from continuous experiences in the workplace), this research aimed to assess the association among the dualistic model of passion (harmonious and obsessive), flow, and job satisfaction in sports coaches. The sample consisted of 172 Brazilian coaches from different sports (69.60% male). Structural equation modeling demonstrated that both forms of passion were positively associated with absorption and intrinsic motivation experience; however, only harmonious passion showed a significant relationship with enjoyment and job satisfaction. Furthermore, a mediating role of flow (work enjoyment and intrinsic motivation) in the relationship between harmonious passion and coaches’ job satisfaction was observed. The results suggest that coaches who demonstrate harmonious passion for the profession tend to have a greater perception of positive experiences at work and feel more satisfied with these activities.
P32 To evaluate prophylactic posaconazole prescribing in children under 12 years with primary immunodeficiency

Published: April 2023

AimCurrent prescribing in our trust, in the absence of a guideline and licensing for prophylactic posaconazole in children under 12 years, is based on a paper by Boonsathorn et al. 20181The purpose of this audit is to evaluate the extent to which prescribing and monitoring of prophylactic oral posaconazole prescribed within our paediatric inpatient population is in line with published recommendations.1Targets were 100% of patients were dosed as recommended1; 100% of trough concentrations for posaconazole were taken within 5–10 days after initial administration; and if trough concentrations are not in range (>0.7 mg/L) was corrective action taken.MethodPatients between the ages of 2 months to 12 years with primary immunodeficiency recorded on their health record as being initiated on prophylactic posaconazole in the last 2 years were identified. Where patients met the inclusion criteria; age, weight, posaconazole formulation, date of initiation of posaconazole, trough concentration, date of trough concentration and dose adjustments were collected. Data was collated and analysed using MS Excel. Caldicott Guardian approval (ID: 9378) was granted by our trust and was added to the clinical effectiveness register (ID: 13451).Results23 patients were included with the mean age of 3.7 years. 84% of patients were dosed as recommended by Boonsathorn et al. 52% of all patients got a trough concentration taken within the 5–10 days and 75% of those patients had a trough concentration of >0.7 mg/L. 25% of patients had concentrations taken in 5–10 days that were <0.7 mg/L and doses were increased. These increased doses were not as recommended.133% of patients had concentrations taken in 5–10 days that greatly exceeded 0.7 mg/L and had dose reductions.ConclusionThe majority of the patients were dosed as recommended and had a trough concentration >0.7 mg/L. Recommendations could be translated into a guideline to include; advising trough concentrations are taken 5–10 days of initial administration to get an accurate picture of the posaconazole concentration. To include recommendations of dose adjustments following <0.7 mg/L trough concentrations to get consistent optimal prescribing. There was no maximum trough concentration for prescribers to adhere so the addition of a maximum trough concentration and recommendations of dose reductions would improve the clinical safety of prescribing prophylactic posaconazole. Limitations of this audit included the limited number of patients that fitted the criteria and results cannot be generalised for all oral formulations as only one patient was prescribed tablets.ReferenceBoonsathorn, S, Cheng I, Kloprogge F,et al.

Topical dilation as first-line treatment for fibrin membrane pupillary-block glaucoma following uncomplicated cataract surgery
Authors: Bennett Sashia , Studsgaard Anne , Telinius Niklas 
Published: April 2023

Fibrin membrane pupillary-block glaucoma is an uncommon complication after phacoemulsification cataract surgery. We present a case treated successfully by pharmacological dilation of the pupil. Previous case reports have recommended the use of Nd:YAG peripheral iridotomy, Nd:YAG membranotomy and intracameral tissue plasminogen activator.The patient presented with intraocular pressure (IOP) of 45 mmHg 2 days after uneventful phacoemulsification cataract surgery. Anterior segment optical coherence tomography revealed that a fibrinous membrane-filled space had formed between the pupillary plane and the implanted intraocular lens.The diagnosis of fibrin membrane pupillary-block glaucoma was made. Initial treatment consisted of IOP-lowering medication and topical pupillary dilation (atropine 1%, phenylephrine hydrochloride 10% and tropicamide 1%). Within 30 min, the dilation broke the pupillary block and the IOP was 15 mmHg. The inflammation was treated with topical dexamethasone, nepafenac and tobramycin. Within a month, the patient reached a visual acuity of 1.0.
