Reference Dependence in Queue Design and Pricing Strategies
Authors: Liu Jian , Zhou Yongpin , Chen Jian , Li Peng 
Published: March 2024

This research investigates the effect of reference dependence on waiting times in service systems which formerly used a first-in-first-out (FIFO) service but have introduced a priority line with a fee. Our model combines reference-dependent gain-loss utility with standard customer utility, and we posit that customers are pleased with shorter-than-expected waiting times, whereas longer-than-expected times lead to dissatisfaction and an increased likelihood of balking. The study explores two scenarios: a captive customer system (CCS) and a noncaptive customer system (NCCS), with a focus on optimal pricing and segmentation strategies for revenue and social welfare maximization. The results reveal that, in a CCS, the service provider should implement observed and unobserved customer segmentation to optimize revenue and social welfare, respectively. In an NCCS, the impact of customer segmentation on revenue maximization depends on the value of regular customers, their loss reference-dependent preferences, and the system’s offered load. Alternatively, if the service provider seeks to maximize social welfare, the provider’s use of customer segmentation relies solely on the system’s offered load and customers’ reference-dependent preferences. Our findings also indicate that reference dependence can have varying impacts under different conditions, suggesting the effectiveness of tailored service and pricing strategies. Notably, a CCS generates more revenue than does an NCCS because of its captive nature, and, surprisingly, increasing the service rate can decrease revenue while improving social welfare. These insights have significant implications for service management strategies for a CCS and an NCCS. Funding: J.

Authors: Guryel Enis , McEwan Jo , Qureshi Amir A. , Robertson Alastair , Ahluwalia Raju 
Published: March 2024

AimsAnkle fractures are common injuries and the third most common fragility fracture. In all, 40% of ankle fractures in the frail are open and represent a complex clinical scenario, with morbidity and mortality rates similar to hip fracture patients. They have a higher risk of complications, such as wound infections, malunion, hospital-acquired infections, pressure sores, veno-thromboembolic events, and significant sarcopaenia from prolonged bed rest.MethodsA modified Delphi method was used and a group of experts with a vested interest in best practice were invited from the British Foot and Ankle Society (BOFAS), British Orthopaedic Association (BOA), Orthopaedic Trauma Society (OTS), British Association of Plastic & Reconstructive Surgeons (BAPRAS), British Geriatric Society (BGS), and the British Limb Reconstruction Society (BLRS).ResultsIn the first stage, there were 36 respondents to the survey, with over 70% stating their unit treats more than 20 such cases per year. There was a 50:50 split regarding if the timing of surgery should be within 36 hours, as per the hip fracture guidelines, or 72 hours, as per the open fracture guidelines. Overall, 75% would attempt primary wound closure and 25% would utilize a local flap. There was no orthopaedic agreement on fixation, and 75% would permit weightbearing immediately. In the second stage, performed at the BLRS meeting, experts discussed the survey results and agreed upon a consensus for the management of open elderly ankle fractures.ConclusionA mutually agreed consensus from the expert panel was reached to enable the best practice for the management of patients with frailty with an open ankle fracture: 1) all units managing lower limb fragility fractures should do so through a cohorted multidisciplinary pathway. This pathway should follow the standards laid down in the "care of the older or frail orthopaedic trauma patient" British Orthopaedic Association Standards for Trauma and Orthopaedics (BOAST) guideline. These patients have low bone density, and we should recommend full falls and bone health assessment; 2) all open lower limb fragility fractures should be treated in a single stage within 24 hours of injury if possible; 3) all patients with fragility fractures of the lower limb should be considered for mobilisation on the day following surgery; 4) all patients with lower limb open fragility fractures should be considered for tissue sparing, with judicious debridement as a default; 5) all patients with open lower limb fragility fractures should be managed by a consultant plastic surgeon with primary closure wherever possible; and 6) the method of fixation must allow for immediate unrestricted weightbearing.Cite this article: Bone Jt Open 2024;5(3):236–242.
‘Shooting in the dark’: implications of the research–practice gap for enhancing research use in adult social care
Authors: Gray Karen , Dibsdall Lisa , Sumpter Linda , Cameron Ailsa , Willis Paul , Symonds Jon , Jones Matthew , McLeod Hugh , Macdonald Geraldine , Cabral Christie 
Published: March 2024

Background:
Despite calls for greater use of research and an appetite to do so within adult social care, a gap persists between research and practice.

Aims and objectives:
To explore views of adult social care staff about research and its application to everyday practice. To understand how these might impact upon research use capacity-building initiatives within adult social care organisations.

Methods:
Thematic analysis of semi-structured qualitative interviews with 25 staff members working within the adult social care departments of three English local authorities.

Findings:
Participants characterised research as feeling separate from practice. They reflected on their use of it in relation to pressures affecting adult social care and identified a lack of relevant research. Research benefiting service users, supporting individual practice or informing organisational decision-making was considered useful. However, research could also be viewed as a luxury where its findings were felt to represent an ‘ideal’ rather than real world of practice or did not accord with practice knowledge or local experience.

Discussion and conclusions:
While participants feel positively towards research, there remains a gap between these perceptions and its use in practice. There remains a need to improve research relevance and accessibility and to clarify its role in decision-making in social care, including where there is no evidence, where evidence challenges existing practice, or where the evidence base is growing. Collaborative partnerships between adult social care organisations, researchers and service users could help to narrow the research–practice gap and support the routine translation of research to practice.
Repeatability of Pentacam-derived intraocular lens decentration measurements and the level of agreement with OPD-Scan III: A prospective observational case series
Authors: Liu Xiaobao , Wu Wenjie , Huang Yulong , Fu Yabo , Huang Yue , Li Qiong 
Published: March 2024

Purpose
This study aimed to assess the repeatability of intraocular lens (IOL) decentration measurements obtained through Pentacam, based on corneal topographic axis (CTA) and pupillary axis (PA), and to evaluate the level of agreement between Pentacam and OPD-Scan III devices in measuring IOL decentration.

Methods
In this prospective observational case series, three measurements were performed with Pentacam to evaluate the repeatability of the measurements. The analysis included the calculation of the mean and standard deviations (SD), conducting a repeated measures analysis of variance (rANOVA), and determining an intraclass correlation coefficient (ICC) to assess the repeatability of the measurements. Moreover, Bland-Altman analysis was employed to assess the agreement between Pentacam and OPD-Scan III devices in measuring IOL decentration. IOL decentration measurements were obtained with respect to both CTA and PA.

Results
A total of 40 eyes from 40 patients were analyzed. The rANOVA revealed no significant difference among three consecutive measurements of IOL decentration obtained with Pentacam. The mean SD of all parameters ranged from 0.04 mm to 0.07 mm. With CTA as the reference axis, the ICC values for Pentacam measurements of IOL decentration were 0.82 mm for the X-axis, 0.76 mm for the Y-axis, and 0.82 mm for spatial distance. When using PA as the reference axis, the corresponding ICC values were 0.87, 0.89, and 0.77, respectively. The 95% limits of agreement for all IOL decentration measurements were wide when comparing Pentacam and OPD-Scan III.

Conclusions
Pentacam demonstrated high repeatability in measuring IOL decentration with respect to both CTA and PA. However, due to poor agreement between Pentacam and OPD-Scan III measurements, caution should be exercised when using data interchangeably between the two devices.
Monitoring the after-effects of ischemic stroke through EEG microstates
Authors: Wang Fang , Yang Xue , Zhang Xueying , Hu Fengyun 
Published: March 2024

Background and purpose
Stroke may cause extensive after-effects such as motor function impairments and disorder of consciousness (DoC). Detecting these after-effects of stroke and monitoring their changes are challenging jobs currently undertaken via traditional clinical examinations. These behavioural examinations often take a great deal of manpower and time, thus consuming significant resources. Computer-aided examinations of the electroencephalogram (EEG) microstates derived from bedside EEG monitoring may provide an alternative way to assist medical practitioners in a quick assessment of the after-effects of stroke.

Methods
In this study, we designed a framework to extract microstate maps and calculate their statistical parameters to input to classifiers to identify DoC in ischemic stroke patients automatically. As the dataset is imbalanced with the minority of patients being DoC, an ensemble of support vector machines (EOSVM) is designed to solve the problem that classifiers always tend to be the majority classes in the classification on an imbalanced dataset.

Results
The experimental results show EOSVM get better performance (with accuracy and F1-Score both higher than 89%), improving sensitivity the most, from lower than 60% (SVM and AdaBoost) to higher than 80%. This highlighted the usefulness of the EOSVM-aided DoC detection based on microstates parameters.

Conclusion
Therefore, the classifier EOSVM classification based on features of EEG microstates is helpful to medical practitioners in DoC detection with saved resources that would otherwise be consumed in traditional clinic checks.

The theory of F-rational signature
Authors: Smirnov Ilya , Tucker Kevin 
Published: March 2024

Abstract
F-signature is an important numeric invariant of singularities in positive characteristic that can be used to detect strong F-regularity.
One would like to have a variant that rather detects F-rationality, and there are two theories that aim to fill this gap: F-rational signature of Hochster and Yao and dual F-signature of Sannai.
Unfortunately, several important properties of the original F-signature are unknown for these invariants.
We find a modification of the Hochster–Yao definition that agrees with Sannai’s dual F-signature and push further the united theory to achieve a complete generalization of F-signature.

Published: March 2024

Abstract

Objectives
According to World Health Organization (WHO),Unhealthy Diet (UD)is a major risk factor for chronic diseases. That’s why it is important to study the UD and its associated factors. Our study aimed to describe the dietary behavior of young high school students and determine associated factors of UD.

Methods
A cross-sectional study was carried out among students of seven high schools in center-eastern Tunisia during the academic year 2021/2022. Data collection was carried out in April2022 by questionnaires. The questions concerned the socio-demographic characteristics, food habits and physical activity. WHO defined UD as the consumption of less than five fruits and vegetables per day. Data analysis was done using SPSS software.

Results
A total of 740 adolescents were included. The mean age was17±1.16 years with extremes ranging from 14to19 years. Sex-ratio was 0.66. UD was found among 91.6 % of the study population. At multivariate analysis, eating cake (aOR=4.062; CI [1.685–9.795]; p=0.002),eating fried-food (aOR=3.239; CI [1.118–9.385]; p=0.03)and consuming sweets (aOR=3.263; CI [1.666–6.394]; p=0.001)were independent risk factors of UD. In the other hand, regular physical activity (aOR=0.524; CI [0.294–0.936]; p=0.029)and having breakfast regularly (aOR=0.523; CI [0.297–0.923]; p=0.025)were independent protective factors of UD.

Conclusions
The findings of this study showed an alarming prevalence of UD. Therefore, it is mandatory to establish effective strategies to support healthy diets and physical activity among adolescents in order to reduce non-communicable diseases related to UD.
Evaluating deformation in FRP boat: Effects of manufacturing parameters and working conditions
Authors: Nhut Pham-Thanh , Tien Dinh Duc , Do Quang Thang 
Published: March 2024

Abstract
Fiber-reinforced plastic (FRP) is utilized in the fabrication of the primary structures of FRP boats. A majority of these structures are produced using molds. Subsequently, these products often experience deformation upon being released from the mold, as well as when they are exposed to high temperatures. Hence, it is crucial to carry out experimental investigations and evaluations related to the deformation of laminated composite structures. The specimens, which are in the form of L-shapes and curve-shapes, are constructed using unsaturated polyester resin and fiberglass material. The study focuses on two independent variables, namely the percentage of hardeners and the temperature during the manufacturing process. The output factor under examination is deformation, which is measured on these specimens. Subsequently, all of the specimens are subjected to varying levels of temperature using an oven as the working condition. The deformation is further assessed based on the experimental findings and regression equation. The results indicate that as the rate of hardener and temperature increase, the level of deformation decreases. Additionally, it was observed that when the temperature rises from 500 to 800°C, the specimens with initial deformation values that are either too high or too low undergo rapid changes. Moreover, the experimental equations can be utilized to predict the values of deformation or input factors.
Through the compression glass: language complexity and the linguistic structure of compressed strings
Authors: Ehret Katharina 
Published: March 2024

Abstract
Against the backdrop of the sociolinguistic-typological complexity debate which is all about measuring, comparing and explaining language complexity, this article investigates how Kolmogorov-based information theoretic complexity relates to linguistic structures. Specifically, the linguistic structure of text which has been compressed with the text compression algorithm gzip will be analysed. One implementation of Kolmogorov-based language complexity is the compression technique (Ehret, Katharina. 2021. An information-theoretic view on language complexity and register variation: Compressing naturalistic corpus data. Corpus Linguistics and Linguistic Theory (2). 383–410) which employs gzip to measure language complexity in naturalistic text samples. In order to determine what type of structures compression algorithms like gzip capture, and how these compressed strings relate to linguistically meaningful structures, gzip’s lexicon output is retrieved and subjected to an in-depth analysis. As a case study, the compression technique is applied to the English version of Lewis Carroll’s Alice’s Adventures in Wonderland and its lexicon output is extracted. The results show that gzip-like algorithms sometimes capture linguistically meaningful structures which coincide, for instance, with lexical words or suffixes. However, many compressed sequences are linguistically unintelligible or simply do not coincide with any linguistically meaningful structures. Compression algorithms like gzip thus crucially capture purely formal structural regularities. As a consequence, information theoretic complexity, in this context, is a linguistically agnostic, purely structural measure of regularity and redundancy in texts.
The Doctrine of Sufficiency as a Contractualist Principle
Authors: Pike Kenneth R. 
Published: March 2024

Abstract
I argue that Harry Frankfurt’s doctrine of sufficiency, properly understood, presents a plausible alternative to egalitarianism. My position may be more general than Frankfurt’s, insofar as he limits himself to economic sufficiency; on my view, insufficiency is a generic reason for the rejection of principles governing permissible behavior. By situating sufficiency within a contractualist framework of moral permissibility, I provide an alternative to common (and, I think, mistaken) characterizations of the doctrine of sufficiency as either subordinate to equality or primarily concerned with maximizing cases of sufficiency.
Snapshot spectral imaging: from spatial-spectral mapping to metasurface-based imaging
Authors: Ding Kaiyang , Wang Ming , Chen Mengyuan , Wang Xiaohao , Ni Kai , Zhou Qian , Bai Benfeng 
Published: March 2024

Abstract
Snapshot spectral imaging technology enables the capture of complete spectral information of objects in an extremely short period of time, offering wide-ranging applications in fields requiring dynamic observations such as environmental monitoring, medical diagnostics, and industrial inspection. In the past decades, snapshot spectral imaging has made remarkable breakthroughs with the emergence of new computational theories and optical components. From the early days of using various spatial-spectral data mapping methods, they have evolved to later attempts to encode various dimensions of light, such as amplitude, phase, and wavelength, and then computationally reconstruct them. This review focuses on a systematic presentation of the system architecture and mathematical modeling of these snapshot spectral imaging techniques. In addition, the introduction of metasurfaces expands the modulation of spatial-spectral data and brings advantages such as system size reduction, which has become a research hotspot in recent years and is regarded as the key to the next-generation snapshot spectral imaging techniques. This paper provides a systematic overview of the applications of metasurfaces in snapshot spectral imaging and provides an outlook on future directions and research priorities.

Mit der vielfältigen und umfassenden Nutzung weltraumgestützter kommerzieller Systeme und Dienstleistungen hat sich die NewSpace-Industrie aktiv an der Verteidigung der Ukraine beteiligt und eine neue Dimension des Weltraums in der Kriegführung aufgezeigt. Der Artikel stellt zunächst die strategische Bedeutung des Weltraums für das Militär, die Verwundbarkeit von Weltraumkapazitäten und die Herausforderungen für deren Schutz dar. Anschließend werden die Auswirkungen weltraumbezogener Vorfälle zu Beginn des Ukraine-Kriegs dargelegt und die entscheidende Rolle von Weltraumkapazitäten in der Kriegführung der Ukraine hervorgehoben. Der Artikel verdeutlicht zum einen die Bedeutung des Weltraums, indem er die Verwicklung nichtstaatlicher Akteure der NewSpace-Industrie in diesen Krieg aufzeigt und Schlussfolgerungen für die zukünftige Rolle des Weltraums und kommerzieller Weltraumakteure in Konflikten und Kriegen zieht. Zum anderen leuchtet er die Konsequenzen, notwendigen Anpassungen und den politischen Handlungs- und Regelungsbedarf in Bezug auf drei Aspekte aus: 1) Militär und Kriegführung, 2) das Verhältnis zwischen Staaten und kommerziellen Akteuren der NewSpace-Industrie sowie 3) die Weltraumpolitik Europas.
Wie ist Rhythmus an Interaktion beteiligt? Sportsoziologische Potenziale einer ethnomethodologisch-empirischen Rhythmusforschung
Authors: Staack Michael , v. Wedelstaedt Ulrich 
Published: March 2024

Zusammenfassung
In vorliegendem Artikel gehen wir der Frage nach, wie Rhythmus als basierendes Element von Interaktion fungiert. Die Sportsoziologie ist ein besonders geeigneter Rahmen für solch eine Forschung. Denn insofern sie als Disziplin sowohl mit der allgemeinen Soziologie wie auch mit anderen sportwissenschaftlichen Disziplinen benachbart ist, bietet sie einen einzigartigen Zugang zur Beforschung spezifischer Rhythmusphänomene im Sport. Empirisch gehen wir dieser Frage am Fall des professionellen Boxsports nach. Mittels ethnomethodologischer/konversationsanalytischer Videoanalyse analysieren wir zwei kurze Videosequenzen aus Wettkampf und Wettkampfvorbereitung. Wir fragen, welche Rolle körperliche Rhythmisierungen in Boxer-Trainer-Interaktionen während des Kampfes und in Rundenpausen zukommt – und wie es den Beteiligten gelingt oder misslingt, diese Rhythmisierungen herzustellen und aufrechtzuerhalten.
