Divergence of tropical cyclone hazard based on wind-weighted track distributions in the Coral Sea, over 50 years
Authors: Miller John , da Silva Guilherme Vieira , Strauss Darrell 
Published: January 2023

AbstractTropical cyclones (TCs) with genesis in the Coral Sea present significant hazards to coastal regions in their surroundings. In addition, the erratic nature of TC tracks is not well understood in this region. Therefore, this study grouped Coral Sea TC tracks over the last fifty years based on K-means clustering of the maximum wind-weighted centroids. This was done in order to extract valuable new cyclone power, track curvature and location related information from their historical track records and to predict their behaviour in the light of a changing climate. TC track variance and curvature (sinuosity) were assessed. Three well-defined clusters of TC tracks were identified, and the results showed differing predominant directions of TC movement by cluster. Track sinuosity was shown to increase from east to west. Only one cluster showed a statistically significant trend (decreasing) in TC frequency. The TC power dissipation index (PDI) was used to reveal that two of the clusters have diverging trends for PDI post-2004. Based on the location of cyclone maximum intensity, only one cluster showed a statistically significant trend (towards the equator). All these findings demonstrated a clear variance in between-cluster hazard and show that TC trends discovered for the southwest Pacific are not manifest or consistent across all clusters.
Nonlinear dynamics of parametrically excited cantilever beams with a tip mass considering nonlinear inertia and Duffing-type nonlinearity

Published: January 2023

AbstractThe response of a parametrically excited cantilever beam (PECB) with a tip mass is investigated in this paper. The paper is mainly focused on accurate prediction of the response of the system, in particular, its hardening and softening characteristics when linear damping is considered. First, the method of varying amplitudes (MVA) and the method of multiple scales (MMS) are employed. It is shown that both Duffing nonlinearity and nonlinear inertia terms govern the hardening or softening behaviour of a PECB. MVA results show that for frequencies around the principal parametric resonance, the term containing a linear combination of nonlinear inertia and Duffing nonlinearity in the frequency response equation can tend to zero, resulting in an exponential growth of the vibrations, and results are validated by numerical results obtained from direct integration (DI) of the equation of motion, while the MMS fails to predict this critical frequency. A criterion for determining the hardening and softening characteristics of PECBs is developed and presented using the MVA. To verify the results, experimental measurements for a PECB with a tip mass are presented, showing good agreement with analytical and numerical results. Furthermore, it is demonstrated that the mass added at the cantilever tip can change the system characteristics, enhancing the softening behaviour of the PECB. It is shown that, within the frequency range considered, increasing the value of the tip mass decreases the amplitude response of the system and broadens the frequency range in which a stable response can exist.
Working Hard or Hardly Working? Gender and Voter Evaluations of Legislator Productivity
Authors: Hargrave Lotte , Smith Jessica C. 
Published: January 2023

AbstractDo women have to work harder in office to be evaluated the same as men? When running for office, studies show that women are, on average, more qualified than men candidates. Once in office, women outperform their men colleagues in sponsoring legislation, securing funding, and in their constituency responsiveness. However, we do not know whether women need to outperform men in their political roles to receive equivalent evaluations. We report on a novel conjoint experiment where we present British voters with paired profiles describing Members of Parliament at the end of their first parliamentary term. Through manipulating the legislative outputs, gender, and party of MPs, we find that voters overall prefer politicians who are productive to politicians who are unproductive, and reward productive politicians in job performance and electability evaluations. However, we find no evidence that productive women are unjustly rewarded, nor do unproductive women face greater punishment than men. Our results suggest that, at least for productivity as measured in parliamentary-based activities, women politicians do not need to work harder than their men colleagues to satisfy voters.
Development of Systems and Futures Thinking Skills by Primary Pre-service Teachers for Addressing Epidemics
Authors: Uskola Araitz , Puig Blanca 
Published: January 2023

Abstract
Science educators highlight the importance of developing systems thinking (ST) and futures thinking (FT) for students to make decisions and to be active citizens that address socioscientific problems. The dimensions related to FT take in this study were three implied in ST and two in the appropriation of the future. The aim of this study is to analyse the level of FT-related dimensions developed by a group of pre-service elementary teachers and how far different activities designed to foster them were effective. Written explanations presented by the participants about the origin of pandemics and possible ways to prevent them, as well as videos developed by small groups with the goal to present a campaign for avoiding future pandemics, were analysed. Based on the literature, five dimensions and up to four levels of performances were identified. After completing the activities, participants were able to relate the three spheres of the “One Health” notion to explain the causes of pandemics. Moreover, they established complex cause-effect relationships between the different factors, although they only constructed monocausal relationships when proposing measures. Participants improved their performance in anticipating the future and identifying themselves as agents of change. The elaboration of concept maps facilitated the development of components and behaviour ST dimensions, and the design of the campaign allowed participants to identify themselves as agents of change. The use of these strategies in science education can contribute to the development of a citizenry capable of understanding and acting on systems.

Authors: Tan Rachel Yi Ping , Rao Nitesh N. , Horwood Christopher M. , Passaris George , Juneja Rajiv 
Published: January 2023

Abstract
Purpose
To evaluate whether symptomatic recurrent nephrolithiasis leads to loss of kidney function.

Methods
Adults who presented to the Emergency Department at least twice with symptomatic and radiologically confirmed nephrolithiasis were retrospectively recruited. Primary endpoint was the change in glomerular filtration rate (GFR) between baseline and at the time of data collection. Secondary endpoints include GFR slope defined as the mean rate of change in GFR from baseline to the end of the study period.

Results
240 patients had recurrent symptomatic nephrolithiasis. Median follow-up was 5.4 years. The median age of first acute presentation was 51.6 years and the median baseline serum creatinine (bsCr) was 85.5 umol/l. 17.5% (n = 42) had worsening GFR, with the average change in GFR of − 8.64 ml/min/1.73 m2 per year. Four patients progressed to ESKD requiring haemodialysis. 14.5% (n = 35) had calcium oxalate stones. Univariate analysis showed older patients (p < 0.001), more symptomatic stone episodes (p < 0.001) and non-calcium-containing stones (p < 0.001) were strongly associated with deteriorating kidney function. Age (p = 0.002) and number of acute stone episodes (p = 0.011) were significant predictive factors when unadjusted to co-morbidities. Age (p = 0.018) was the only predictive factor of worsening GFR when adjusted for co-morbidities. Average mean GFR slope was − 2.83/min/1.73 m2 per year.

Conclusions
Recurrent symptomatic nephrolithiasis is associated with loss of kidney function, in older patients, increased episodes of symptomatic nephrolithiasis and non-calcium-containing stones. Age is the only predictive factor for progression to chronic kidney disease in this subgroup.
Personalized federated learning with model interpolation among client clusters and its application in smart home

Published: January 2023

AbstractThe proliferation of high-performance personal devices and the widespread deployment of machine learning (ML) applications have led to two consequences: the volume of private data from individuals or groups has exploded over the past few years; and the traditional central servers for training ML models have experienced communication and performance bottlenecks in the face of massive amounts of data. However, this reality also provides the possibility of keeping data local for ML training and fusing models on a broader scale. As a new branch of ML application, Federated Learning (FL) aims to solve the problem of multi-party joint learning on the premise of protecting personal data privacy. However, due to the heterogeneity of devices, including network connection, network bandwidth, computing resources, etc., it is unrealistic to train, update and aggregate models in all devices in parallel, while personal data is often not independent and identically distributed (Non-IID) due to multiple reasons. This reality poses a challenge to the speed and convergence of FL. In this paper, we propose the pFedCAM algorithm, which aims to improve the robustness of the FL system to device heterogeneity and Non-IID data, while achieving some degree of federation model personalization. pFedCAM is based on the idea of clustering and model interpolation by classifying heterogeneous clients and performing FedAvg algorithm in parallel, and then combining them into personalized federated global models by inter-cluster model interpolation. Experiments show that the accuracy of pFedCAM improves 10.3% on Fashion-MNIST and 11.3% on CIFAR-10 compared to the benchmark in the case of Non-IID data. In the end, we applied pFedCAM in HomeProtect, a smart home privacy protection framework we designed, and achieved good practical results in the case of flame recognition.
Engagement in entrepreneurship after business failure. Do formal institutions and culture matter?
Authors: Uriarte Sebastián , Espinoza-Benavides Jorge , Ribeiro-Soriano Domingo 
Published: January 2023

AbstractDespite the extensive literature on the relationship between entrepreneurship and institutions, there is limited knowledge of the relationship between institutions and engagement after failure. This study compares the entrepreneurial engagement of entrepreneurs who have recently experienced failure and individuals without entrepreneurial experience, emphasizing the interaction of government policies and programmes (formal institutions) and individualistic/collectivist cultures (informal institutions) with business failure and its impact on entrepreneurial engagement. We test our hypotheses using multilevel analysis on a large cross-sectional sample that combines individual-level data from the Global Entrepreneurship Monitor (GEM) database with country-level data from 49 economies. We provide evidence of selection bias for the entrepreneurial engagement of entrepreneurs after failures and of the role of culture as a significant aspect of re-entry into entrepreneurship. Therefore, our evidence helps reinforce the view that postfailure entrepreneurs are a special group of entrepreneurs and validates the contribution of institutional economic theory in explaining this phenomenon, especially the key role of informal institutions.
The times they are a-changin’: profiling newly tenured business economics professors in Germany over the past thirty years
Authors: Fernandes Mario , Walter Andreas 
Published: January 2023

AbstractThis study examines how the profiles of newly tenured business economics professors in Germany have changed over the past thirty years. We document how business economics professors have become more diverse over time, e.g., in terms of their gender and the internationality of their education. Furthermore, we show that the size of the professional networks of newly tenured professors increased strongly during our investigation period and that those professors who obtained tenure more recently publish with a stronger international focus than their peers who obtained tenure earlier. Most importantly, we find that the publication requirements for newly tenured business economics professors have changed over the past thirty years. Specifically, we document increased requirements for publications in highly renowned international journals. However, we also find that traditional German business economics journals (e.g., the Journal of Business Economics and the Schmalenbach Business Review) remain highly relevant outlets for recently tenured business economics professors. Thus, by documenting and quantifying these effects, our study contributes to research on business economics professors by highlighting how the times they are a-changin’.

Published: January 2023

AbstractTo tackle the twenty-first-century challenges for sustainability, a deeper understanding of their complexity is needed. Hence, interdisciplinary human–environment research integrating knowledge, perspectives, and solutions across scales is crucial. Yet, questions of ‘scale’ and ‘scaling’ continue to challenge human–environment research. Despite substantial scholarly attention to scales, no unified definitions and understanding exist, causing confusion among researchers. In this paper, we aim to provide clarity to the challenges and potential solutions to bridging scales in interdisciplinary human–environment research as well as identify leverage points and arenas of change that would enable it. We used a three-step methodology to (a) identify the challenges and solutions based on a survey of 82 interdisciplinary researchers, (b) prioritise the challenges and solutions based on expert elicitation, and (c) organise the solutions according to their potential for leveraging change at three system arenas: individual researchers, institutions and organisations, and the wider academic structures. The main challenges ranged from issues related to differences in research approaches, lack of resources for deeper collaborations, or conflicting perspectives on problem and scale definitions, to miscommunication. The specific solutions linked to these challenges were predominantly related to the potential of improving the research process through open communication, data sharing, or new techniques for upscaling or downscaling results. We argue that bridging scales requires open and humble conversations across disciplines on scale understandings as well as improved collaboration through data sharing, method development, result dissemination, and contribution to theory. Facilitating such collaboration requires enabling spaces of interaction across three systemic arenas: the individual researcher’s personal commitment to open communication and reflection, the research institution’s capacity to enable interdisciplinary spaces, and the wider academic system valuing and supporting interdisciplinary and cross-scale initiatives.
Networks of action situations in point-source pollution: the case of winery wastewater in Aragon, Spain

Published: January 2023

AbstractIn this article, we offer an analysis of point-source water pollution governance in the European agri-food sector. Specifically, we tackle the case study of the wine industry in Aragon (Spain) through the lenses of the networks of action situations approach. We unveil key strategic decisions of wine producers in relation to compliance with water discharge regulations and explore the feasibility and effectiveness of potential solutions. According to our quantitative and qualitative analyses, the problem of peak load discharges in the sector can be explained by the strategic behavior of wine producers in the context of enforcement deficits, as well as by particularities of the wine production process, and controversies around the construction and management of public treatment plants. Coordination among wine producers and public treatment plant managers to invest in in-house treatment infrastructure or to smooth discharges out so they fit the capacity of treatment plants would be a promising solution; however, economic incentives and tightened enforcement of discharge regulations would also be necessary.

Paediatric robotic surgery: a narrative review
Authors: O’Brien Lukas Padraig , Hannan Enda , Antao Brice , Peirce Colin 
Published: January 2023

AbstractThe benefits of minimally invasive surgery (MIS) compared with traditional open surgery, including reduced postoperative pain and a reduced length of stay, are well recognised. A significant barrier for MIS in paediatric populations has been the technical challenge posed by laparoscopic surgery in small working spaces, where rigid instruments and restrictive working angles act as barriers to safe dissection. Thus, open surgery remains commonplace in paediatrics, particularly for complex major surgery and for surgical oncology. Robotic surgical platforms have been designed to overcome the limitations of laparoscopic surgery by offering a stable 3-dimensional view, improved ergonomics and greater range of motion. Such advantages may be particularly beneficial in paediatric surgery by empowering the surgeon to perform MIS in the smaller working spaces found in children, particularly in cases that may demand intracorporeal suturing and anastomosis. However, some reservations have been raised regarding the utilisation of robotic platforms in children, including elevated cost, an increased operative time and a lack of dedicated paediatric equipment. This article aims to review the current role of robotics within the field of paediatric surgery.

Published: January 2023

AbstractHybrid-operating rooms (hybrid-OR) combine high-resolution 2D images and 3D-scans with the possibility of 3D-navigation and allow minimal invasive pedicle screw placement even in the upper thoracic spine. The disadvantage of high cost and increased radiation needs to be compensated with high accuracy and safety. The hybrid operating room consists of a floor-based flat-panel robotic C-arm with 3D-scan capability (Artis Zeego, Siemens; Germany) combined with navigation (BrainLAB Curve, BrainLAB; Germany). Through a minimally invasive incision, a Jamshidi needle was advanced through the pedicle and a K-wire was placed. If 2D image quality did not allow safe placement 3D-navigation was used to place the K-wire. Position was controlled through a 3D-Scan and corrected if necessary before screw placement. Postoperative CTs evaluated screw perforation grade with grade I when completely within the pedicle, II < 2 mm, III 2–4 mm, and IV > 4 mm outside the pedicle. Overall, 354 screws were placed in T1–T6, 746 in the lower thoracic spine T7–T12 and 645 in the L1-L5. Navigation was mainly used in upper thoracic spine cases (31 of 57). In 63 out of 326 cases K-wire was corrected after the 3D-Scan. Overall, 99.1% of the screws showed perforation less than 2 mm. Mean radiation was 13.3 ± 11.7 mSv and significantly higher in the upper thoracic spine and in navigated procedures. Despite higher costs and radiation, the hybrid-OR allows highest accuracy and therefore patient safety in minimal invasive pedicle screw placement in the thoracic and lumbar spine.

AbstractThe objective is to evaluate and apply the robot-assisted endoscopic surgical technique for treatment of patent ductus arteriosus (PDA) in children. Clinical data of 106 children with PDA who underwent robot-assisted endoscopic operation were retrospectively analyzed from August, 2020 to March, 2022. Demographic and preoperative data were collected, including the patient’s age, weight, diameter of the ductus arteriosus, operation time, length of postoperative hospital stay, postoperative complications and hospitalization cost. The age ranged from 6 months to 12 years with median age of 2.5 years. In addition, the weight ranged from 6.6 kg (kg) to 51.6 kg with median weight of 12.5 kg. Patients who received transcatheter PDA closure were also enrolled during the same period. Clinical features and perioperative data were compared between the two groups. All the 106 cases underwent robotically assisted surgery for PDA ligation. No one was converted to thoracotomy. The length of operation time was 15–84 min, with an average of 39.4 min. There was no obvious bleeding during the operation. The length of postoperative hospital stays were 1–3 days, with an average of 1.1 ± 0.2 days, which was significantly shorter than that of patients underwent transcatheter approach PDA closure (2.2 ± 0.2 days) (p < 0.05). The average hospitalization costs were US$ 8180 in the 106 patients, which were more expensive than that of ones who received transcatheter procedure (US$ 5076 ± 406) (p < 0.05). Only one case was found to have residual ductus shunt during early postoperative follow-up. One case was found with recurrent laryngeal nerve injury. The two cases recovered after 3 months of follow-up. The median duration of follow-up was 12 (1–20) months. No other short-term complications occurred during the follow-up period. Robotic surgical technique for PDA ligation in children is a safe, effective and reliable surgical method with less trauma, faster recovery and fewer surgical risks. This approach should be considered as an option in children patients requiring PDA ligation.

Published: January 2023

Abstract
Cystic hygroma (CH) is a benign congenital lymphatic malformation, occurring predominantly in children, typically as an asymptomatic neck mass. Surgical resection or sclerotherapy is the recommended treatment options. A retrospective review of four cases of adult-onset CH was performed over 2 years by a single surgeon across two institutions. Four patients (two females, median age 31.5 years) who presented with supraclavicular neck masses (range 5–17 cm) are discussed. Ultrasound and MRI demonstrated supraclavicular masses, suggestive of CH. All patients underwent surgical resection. Post-operative courses were uncomplicated, with a mean length of stay of 4 days. All histological samples returned as CH. As of yet, there are no guidelines on the management of CH. Individualised care tailored to each patient, following careful discussion is the most prudent approach. This study demonstrates that surgical resection is a safe and effective treatment for adults in this rarely encountered clinical entity.
