AimsExcessive posterior pelvic tilt (PT) may increase the risk of anterior instability after total hip arthroplasty (THA). The aim of this study was to investigate the changes in PT occurring from the preoperative supine to postoperative standing position following THA, and identify factors associated with significant changes in PT.MethodsSupine PT was measured on preoperative CT scans and standing PT was measured on preoperative and one-year postoperative standing lateral radiographs in 933 patients who underwent primary THA. Negative values indicate posterior PT. Patients with > 13° of posterior PT from preoperative supine to postoperative standing (ΔPT ≤ -13°) radiographs, which corresponds to approximately a 10° increase in functional anteversion of the acetabular component, were compared with patients with less change (ΔPT > -13°). Logistic regression analysis was used to assess preoperative demographic and spinopelvic parameters predictive of PT changes of ≤ -13°. The area under receiver operating characteristic curve (AUC) determined the diagnostic accuracy of the predictive factors.ResultsPT changed from a mean of 3.8° (SD 6.0°)) preoperatively to -3.5° (SD 6.9°) postoperatively, a mean change of -7.4 (SD 4.5°; p < 0.001). A total of 95 patients (10.2%) had ≤ -13° change in PT from preoperative supine to postoperative standing. The strongest predictive preoperative factors of large changes in PT (≤ -13°) from preoperative supine to postoperative standing were a large posterior change in PT from supine to standing, increased supine PT, and decreased standing PT (p < 0.001). Flexed-seated PT (p = 0.006) and female sex (p = 0.045) were weaker significant predictive factors. When including all predictive factors, the accuracy of the AUC prediction was 84.9%, with 83.5% sensitivity and 71.2% specificity.ConclusionA total of 10% of patients had > 13° of posterior PT postoperatively compared with their supine pelvic position, resulting in an increased functional anteversion of > 10°. The strongest predictive factors of changes in postoperative PT were the preoperative supine-to-standing differences, the anterior supine PT, and the posterior standing PT. Surgeons who introduce the acetabular component with the patient supine using an anterior approach should be aware of the potentially large increase in functional anteversion occurring in these patients.Cite this article: Bone Joint J 2024;106-B(3 Supple A):74–80.

AimsProfessional dancers represent a unique patient population in the setting of hip arthroplasty, given the high degree of hip strength and mobility required by their profession. We sought to determine the clinical outcomes and ability to return to professional dance after total hip arthroplasty (THA) or hip resurfacing arthroplasty (HRA).MethodsActive professional dancers who underwent primary THA or HRA at a single institution with minimum one-year follow-up were included in the study. Primary outcomes included the rate of return to professional dance, three patient-reported outcome measures (PROMs) (modified Harris Hip Score (mHHS), Hip disability and Osteoarthritis Outcome Score for Joint Replacement (HOOS-JR), and Lower Extremity Activity Scale (LEAS)), and postoperative complications.ResultsA total of 49 hips in 39 patients (mean age 56 years (SD 13); 80% female (n = 39)) were included. Mean follow-up was 4.9 years (SD 5.1). Of these 49 hips, 37 THAs and 12 HRAs were performed. In all, 96% of hips returned to professional dance activities postoperatively. With regard to PROMs, there were statistically significant improvements in mHHS, HOOS-JR, and LEAS from baseline to ≥ one year postoperatively. There were complications in 7/49 hips postoperatively (14%), five of which required revision surgery (10%). There were no revisions for instability after the index procedure. Two complications (5.4%) occurred in hips that underwent THA compared with five (42%) after HRA (p = 0.007), though the difference by procedure was not significantly different when including only contemporary implant designs (p = 0.334).ConclusionActive professional dancers experienced significant improvements in functional outcome scores after THA or HRA, with a 96% rate of return to professional dance. However, the revision rate at short- to mid-term follow-up highlights the challenges of performing hip arthroplasty in this demanding patient population. Further investigation is required to determine the results of THA versus HRA using contemporary implant designs in these patients.Cite this article: Bone Joint J 2024;106-B(3 Supple A):17–23.

AimsIt is important to analyze objectively the hammering sound in cup press-fit technique in total hip arthroplasty (THA) in order to better understand the change of the sound during impaction. We hypothesized that a specific characteristic would present in a hammering sound with successful fixation. We designed the study to quantitatively investigate the acoustic characteristics during cementless cup impaction in THA.MethodsIn 52 THAs performed between November 2018 and April 2022, the acoustic parameters of the hammering sound of 224 impacts of successful press-fit fixation, and 55 impacts of unsuccessful press-fit fixation, were analyzed. The successful fixation was defined if the following two criteria were met: 1) intraoperatively, the stability of the cup was retained after manual application of the torque test; and 2) at one month postoperatively, the cup showed no translation on radiograph. Each hammering sound was converted to sound pressures in 24 frequency bands by fast Fourier transform analysis. Basic patient characteristics were assessed as potential contributors to the hammering sound.ResultsThe median sound pressure (SP) of successful fixation at 0.5 to 1.0 kHz was higher than that of unsuccessful fixation (0.0694 (interquartile range (IQR) 0.04721 to 0.09576) vs 0.05425 (IQR 0.03047 to 0.06803), p < 0.001). The median SP of successful fixation at 3.5 to 4.0 kHz and 4.0 to 4.5 kHz was lower than that of unsuccessful fixation (0.0812 (IQR 0.05631 to 0.01161) vs 0.1233 (IQR 0.0730 to 0.1449), p < 0.001; and 0.0891 (IQR 0.0526 to 0.0891) vs 0.0885 (IQR 0.0716 to 0.1048); p < 0.001, respectively). There was a statistically significant positive relationship between body weight and SP at 0.5 to 1.0 kHz (p < 0.001). Multivariate analyses indicated that the SP at 0.5 to 1.0 kHz and 3.5 to 4.0 kHz was independently associated with the successful fixation.ConclusionThe frequency bands of 0.5 to 1.0 and 3.5 to 4.0 kHz were the key to distinguish the sound characteristics between successful and unsuccessful press-fit cup fixation.Cite this article: Bone Jt Open 2024;5(3):154–161.

Published: February 2024

Background
Variations in hepatic arteries are frequently encountered during pancreatoduodenecomy. Identifying anomalies, especially the problematic aberrant right hepatic artery (aRHA), is crucial to preventing vascular-related complications. In cases where the middle hepatic artery (MHA) branches from aRHAs, their injury may lead to severe liver ischemia. Nevertheless, there has been little information on whether MHA branches from aRHAs. This study aimed to investigate the relationship between aRHAs and the MHA based on the embryological development of visceral arteries.

Methods
This retrospective study analyzed contrast-enhanced computed tomography images of 759 patients who underwent hepatobiliary-pancreatic surgery between January 2011 and August 2022. The origin of RHAs and MHA courses were determined using three-dimensional reconstruction. All cases of aRHAs were categorized into those with or without replacement of the left hepatic artery (LHA).

Results
Among the 759 patients, 163 (21.4%) had aRHAs. Five aRHAs patterns were identified: (Type 1) RHA from the gastroduodenal artery (2.7%), (Type 2) RHA from the superior mesenteric artery (SMA) (12.7%), (Type 3) RHA from the celiac axis (2.1%), (Type 4) common hepatic artery (CHA) from the SMA (3.5%), and (Type 5) separate branching of RHA and LHA from the CHA (0.26%). The MHA did not originate from aRHAs in Types 1–3, whereas in Type 4, it branched from either the RHA or LHA.

Conclusions
Based on the developmental process of hepatic and visceral arteries, branching of the MHA from aRHAs is considered rare. However, preoperative recognition and intraoperative anatomical assessment of aRHAs is essential to avoid injury.

The results of the development of optimal parameters for the extraction process of polysaccharides isolated from the shells of horse chestnut fruits collected on the territory of Tashkent and the Tashkent region of the Republic of Uzbekistan are presented. To identify the optimal indicators affecting the extraction processes, the influence of the following parameters on the yield of polysaccharides was studied: the ratio of raw materials: extractant, the extraction rate, the extraction temperature, the degree of evaporation. It has been established that at ratios of raw materials : extractant of 1 : 30, the highest yield of the final product is observed leads to a significant increase in the yield of the final product. The influence of the temperature regime on the yield of polysaccharides was carried out in the temperature range from 25 to 120 °С. At the same time, under constant conditions of the bath modulus of 1 : 30 and the duration of extraction of 2 hours with varying temperature, the highest yield of polysaccharides is observed at a temperature of 95 °С. The optimal degree of evaporation of the extract, in which no large losses of the final product are observed, is the degree of evaporation by 4 times. To assess the influence of technological parameters on the change in qualitative or quantitative indicators of the quality of PS, a one-way analysis of variance was studied for each experiment. Analysis of variance showed the significance of the Fisher criterion, since the p-value is less than 0.05, therefore, the influence of the studied parameters on the yield of polysaccharides can be considered proven. Keywords: extraction, aqueous fraction, extractant, analysis of variance.

Published: February 2024

Aim: The analysis of the flow experience of pre-service teachers in educational drama practices and the effect of the practices on the attitude towards creative drama lessons reveal the purpose of the study. It is of great importance for physical education teachers to use creative drama practices as an effective teaching method in physical education and sports lessons, both in terms of their personal development and professional development.
Method: The study was designed with a pre-test-post-test control group experimental design, one of the true experimental designs, and one of the quantitative research methods. In addition to the demographic information form, the "Flow Experience Scale" and "Attitude Scale towards Creative Drama Lessons" were applied to the participants as measurement tools. The distribution of the participant's demographic information was analyzed by frequency analysis. T-test independent groups analyzed the participants' pre-test and post-test scale scores, and the change in the pre-test and post-test scores of the scales according to demographic information was analyzed by t-test in independent groups and one-way analysis of variance. A regression model was tested to determine the effect of reason on anxiety. Analyses were performed with SPSS 20.0 software at a 95% confidence level.
Findings and Conclusions: As a result, there was no significant difference between the attitude scale scores towards flow experience and creative drama course of the students participating in the research according to their age, gender, income level, place of residence, and activity type, and between the pre-tests and post-tests of the scales. However, a significant difference was detected between the pre-test and post-test scores of the flow experience scale anxiety sub-dimension and the flow sub-dimension of the academic achievement variable. In addition, although there was no significant difference in terms of the variables mentioned, it was noted that the flow experience flow and anxiety subscale scores were low. In contrast, the attitude scores towards the creative drama course were high.

The issue of creative thinking skills in elementary school students is very basic because to achieve learning success in science learning at the elementary school level, it is necessary to increase creative thinking skills in elementary school students. The purpose of this study is to determine the development of the Learning Cycle learning model to improve the creative thinking ability of elementary school students in science learning. This research is an experimental study, which looks at the causal relationship. There were two groups of classes compared in this study, namely the control class and the experiment. Data collection is quantitative data obtained from pretest and posttest results in control classes and experiments. Then to see the improvement of students' abilities from the initial test to the final test using normal Gain scores. The results of the analysis can be concluded that learning with the Learning Cycle model can improve the creative thinking ability of grade IV elementary school students in science learning. In addition, conventional learning can also improve the creative thinking ability of grade IV elementary school students in science learning. However, based on quantitative data collection obtained from pretest and posttest results in control classes and experiments, there are very significant differences in the increase in creative thinking skills of grade IV elementary school students in science learning.
Yuji Ijiri’s Fairness Question in Accounting: A Deontological Game Theoretic Approach
Authors: Kim Tae Wan , Liang Pierre Jinghong , Hooker John 
Published: March 2024

Abstract
We revisit the question initially raised by Yuji Ijiri about the notion of fairness in accounting. We argue that the fairness question was important then and remains relevant today. First we situate Ijiri’s question in relevant debates in the history of accounting thoughts and in contemporary debates. Then we develop a framework of fair flow of information for accounting practices. To do so, we draw upon deontological ethical theory and the generalization principle, in particular. We invite a counter-example from the game-theoretic phenomenon of signal jamming to challenge the generalization principle. By addressing the challenge, we further clarify the appropriate uses of the generalization principle.
Dies ist kein Liebeslied
Authors: Dahm Margit 
Published: March 2024

Abstract
This paper examines the ›Eneasroman‹ of Heinrich von Veldeke within the context of its co-transmission. The different composite manuscripts, combining the ›Eneasroman‹ with various co-texts, raise the question of what conclusions can be drawn from them about the understanding and reception of the novel. It becomes obvious that the surviving compilations, all of them from the late Middle Ages, do not aim at highlighting the elaborate semantics of love. Instead, various historiographical and epistemological connections between the ›Eneasroman‹ and its accompanying texts are established, which emphasize the historical dimensions of the novel and the salvational significance of Eneas as the progenitor of the Romans.
More on the Influence of Gender Equality on Gender Differences in Economic Preferences
Authors: Cerioli Sara , Formozov Andrey 
Published: March 2024

Abstract
This study replicates and extends the work of Falk and Hermle (2018. “Relationship of Gender Differences in Preferences to Economic Development and Gender Equality.” Science 362 (6412): eaas9899), who hypothesized that gender differences in economic preferences (patience, altruism, willingness to take risks, negative and positive reciprocity, and trust) were related to economic development and gender equality. While we were able to replicate their main results, we found that a number of methodological choices called for reexamination. Specifically, the use of an ad hoc gender equality index built by the authors lacked systematic justification, which led us to employ solely well-established indexes from gender studies in the subsequent analysis. This new analysis confirmed a positive and statistically significant association between aggregated gender differences in economic preferences and economic development conditional on gender equality. However, in contrast to the original article, the evidence of the relationship between gender differences and gender equality conditional on economic development was weak. We also investigated the relationships for the separate economic preferences and found that economic development predicts gender differences in all six preferences, whereas gender equality seems to have a negligible or null influence on most of them. Our findings provide a more nuanced view of the gender differences in economic preferences, with possible implications for policy-making.

Abstract
The self-piercing riveting (SPR) experiences problems of poor forming qualities and mechanical properties during joining aviation alloy sheet materials. To address this issue, a novel combined process nominated ultrasonic self-piercing riveting (USPR) is carried out to join a 5A06 aluminium alloy and a TA1 titanium alloy sheets. The forming qualities, mechanical properties, failure modes, and mechanisms of USPR and SPR joints are comprehensively investigated. The results showed that the mechanical properties of the USPR joints were enhanced due to the welding formation of a solid phase between the specimen sheets and the degree of solid phase. The investigation showed that the welding was mainly affected by the material of the upper sheet. However, the welding also increased the brittleness of the rivet to some extent. The failure modes of the joints are affected by the welding process. The results determined that APL, AFD, and AEA of USAA joints were improved by 25.6 %, 31.3 %, and 88.8 %, respectively. The performance of the USPR joints with 5A06 aluminum alloy as the upper sheet is improved more than 88.8 % after the welding process. The combined method can be advantageous and supportive for automotive and spacecraft applications.
