Published: November 2023

AbstractAimWork‐related violence is a significant problem in healthcare settings and emergency departments are one of the highest at‐risk locations. There have been significant challenges in identifying successful risk‐mitigation strategies to reduce the incidence and impact of work‐related violence in this setting. This research explores the perspectives of clinical staff who routinely use violence risk assessment to provide recommendations for improvements.DesignThis qualitative research used interviews of staff who routinely use of the Bröset Violence Checklist in an emergency department. The study was conducted in April 2022.MethodInterview transcripts were subjected to Thematic Analysis to explore participants' clinical experiences and judgements about the utility of the Bröset Violence Checklist.ResultsEleven staff participated in semi‐structured interviews. Participants described themes about the benefits of routine violence risk assessment and the influence of the subjective opinion of the scorer with respect to the emergency department patient cohort. Four categories of violence risk factors were identified: historical, clinical, behavioural and situational. Situational risks were considered important for tailoring the tool for context‐specificity. Limitations of the BVC were identified, with recommendations for context‐specific indicators.ConclusionRoutine violence risk assessment using the Bröset Violence Checklist was deemed useful for emergency departments, however, it has limitations.ImpactThis study's findings offer potential solutions to reduce violence affecting front‐line workers and practical processes that organizations can apply to increase staff safety.ImplicationsThe findings produced recommendations for future research and development to enhance utility of the Bröset Violence Checklist.Reporting MethodEQUATOR guidelines were adhered to and COREQ was used.Patient or Public ContributionNo patient or public contribution was involved in this study.
The Limits of EU Market Power in Migration Externalization: Explaining Migration Control Provisions in EU Preferential Trade Agreements
Authors: Hoffmeyer‐Zlotnik Paula , Lavenex Sandra , Lutz Philipp 
Published: November 2023

AbstractThe European Union (EU) increasingly seeks cooperation with transit and sending countries to prevent irregular migration and enforce returns. Yet, these countries have little incentives to engage in such cooperation. To overcome interest asymmetries, the EU has sought to link trade and migration control in its preferential trade agreements (PTAs). Drawing on a comprehensive dataset of migration provisions in all PTAs signed between 1960 and 2020 and a qualitative analysis of key policy documents, we show that the inclusion of such provisions does not follow patterns of interdependence and strategic priorities resulting from problem pressure. Rather, the proliferation of migration control provisions in EU PTAs is best explained by the institutional framework guiding the negotiation of these provisions. Whilst reflecting the political will to use PTAs as a ‘carrot’ to incite third‐country cooperation, these findings also show the limits of targeted action on migration control via commercial policies.

AbstractA cohort of Chinook salmon juveniles was vaccinated, with an autogenous bivalent vaccine against New Zealand RLOs (NZ‐RLO1) and Tenacibaculum maritimum. A proportion of the cohort was not vaccinated to act as controls. At smoltification, the fish were challenged with NZ‐RLO1, NZ‐RLO2, or T. maritimum. We found that challenge with T. maritimum by immersion in (7.5 × 105 cfu/mL of water) did not yield any pathology. Challenge with RLOs produced clinical signs that were more or less severe depending on the challenge route, dose or vaccination status. Survival was significantly higher for vaccinated fish within the groups challenged with NZ‐RLO1 by intraperitoneal injection with a relative percent survival (RPS) of 48.84%. Survival was not significantly different between vaccinated and non‐vaccinated fish for groups challenged with NZ‐RLO2 by intraperitoneal injection or by NZ‐RLO1 by immersion. Yet, anecdotally the clinical disease presentation (manifesting as haemorrhagic, ulcerative skin lesions) was more severe for the non‐vaccinated fish. This study demonstrates that autogenous vaccine against NZ‐RLO is protective against severe disease and death by NZ‐RLO1 challenge which warrants implementation and further evaluation under field conditions. Yet, this study also highlights the importance of the route of administration and dose when evaluating pathogenicity and vaccine efficacy.

AbstractObjectiveThis study aimed to examine patterns of mother–father coparenting relationship quality and their associations with child empathy, emotional insecurity, and behavior problems in families with low income.BackgroundGiven the growing number of nonmarital births and the high risk of relationship dissolution among cohabiting couples living with low income, it is important to examine the coparenting relationships among racially diverse unmarried couples from low‐income contexts. To date, little research has assessed patterns of coparenting relationships and their associations with child socioemotional outcomes among this population.MethodsParticipants were 4,266 unmarried couples and their preschool‐aged children from the Building Strong Families study. Latent profile analysis (LPA) was conducted.ResultsLPA of survey data from mothers and fathers revealed four coparenting patterns: Profile 1: low quality, more negative maternal coparenting perceptions (7.2%); Profile 2: moderate‐high quality, high congruence, slightly more negative paternal coparenting perceptions (25.2%); Profile 3: low congruence, severely more negative maternal coparenting perceptions (11.8%); and Profile 4: mutual high‐quality coparenting (55.8%).ConclusionChildren of parents with the mutual high‐quality coparenting profile had the most positive outcomes according to maternal reports of child socioemotional development. Highly congruent and positive perceptions of the other parent as a coparent were found to be significant promotive factors for positive child socioemotional development.ImplicationsFamily strengthening policies and programs for unmarried couples with low income should target and support the development of mutually satisfying, high‐quality coparenting relationships, with the ultimate goal to improve developmental outcomes for young children in such families.

Published: November 2023

AbstractChlorogenic acid (CGA), also known as 3‐caffeioylquinic acid or coffee tannin, is a water‐soluble polyphenol phenylacrylate compound produced through the shikimate pathway by plants during aerobic respiration. CGA widely exists in higher dicotyledons, ferns and many Chinese medicinal materials, and enjoys the reputation of ‘plant gold’. Here, we summarized the source, chemical structure, biological activity functions of CGA and its research progress in pigs, aiming to provide a more comprehensive understanding and theoretical basis for the prospect of CGA replacing antibiotics as a pig feed additive.
Patents and unjustified threats—Legal solutions in Australia

Published: November 2023

AbstractWhile intellectual property laws protect rights holders from infringement of their intellectual property, these laws also protect against abuse of those rights where rights holders unjustifiably threaten competitors with infringement proceedings. The introduction of additional damages for flagrant unjustified threats under the recent Intellectual Property Laws Amendment (Productivity Commission Response Part 1 and Other Measures) Act 2018 (Cth) may benefit an alleged infringer who is not found to have infringed a valid patent. In particular, new section 128(1A) to the Patents Act 1990 allows additional damages to be awarded against a person for making blatant unjustified threats of infringing a patent. In cases where it is difficult to determine the loss and ordinary damages cannot be awarded, a court could award a nominal amount in compensation, but the difficulty lies in whether, in some cases, damages can be awarded at all. This raises the need to consider other legal avenues to address the issue of unjustified threats relating to patented inventions. In this paper we have identified four such other legal avenues being: specific provisions of the Australian Consumer Law; the misuse of market power provisions in s 46 Competition and Consumer Act 2010 (Cth); the duty of care and diligence in s 180 Corporations Act 2001 (Cth); and the law of joint tortfeasorship. Each of these potential legal solutions will be examined in turn however a comparison of remedies, or interactions with the laws of evidence, and exploration of costs are beyond the scope of this analysis. Further while we acknowledge that other Australian legislation provides a cause of action arising from the making of unjustifiable threats, such as in the Copyright Act 1968, the Trade Marks Act 1995, the Designs Act 2003 and the Circuit Layouts Act 1986, this paper is focused on the Patents Act 1990 only.

AbstractBackgroundRight versus left kidney donor nephrectomy remains a controversial topic in renal transplantation given the increased incidence of right kidney vascular anomalies and associated venous thrombosis. We present the case of a 3‐year‐old pediatric recipient with urethral atresia and end‐stage kidney disease who received a robotically procured living donor right pelvic kidney with two short same‐size renal veins and a short ureter.MethodsWe utilized a completely deceased iliac vein system (common iliac vein with both external and internal veins) to extend the two renal veins. Due to the distance between both renal veins, the external iliac vein was anastomosed to the upper hilum renal vein, and the internal iliac vein was anastomosed to the lower hilum renal vein. The donor's short ureter was anastomosed to the recipient's ureter end‐to‐side.ResultsThe patient had immediate graft function and there were no post‐operative complications. Renal ultrasound was unremarkable at 48 hours post‐transplant. Serum creatinine was 0.5 mg/dL at 3 months post‐transplant.ConclusionWe demonstrate the successful transplantation of a robotically procured right pelvic donor kidney with two short renal veins using a deceased donor iliac vein system for venous reconstruction without increasing technical complications. This technique of venous reconstruction can be used in right kidneys with similar anatomical variations without affecting graft function.

AbstractImagery has been associated with cardiovascular and psychological responses to stress; however, the mechanisms underlying this association are not fully understood. The present study examined if the ability to image mastering challenging or difficult situations moderated the relationship between heart rate reactivity and perceptions of stress and physiological arousal experienced during acute stress. Four hundred and fifty‐eight participants completed a standardized laboratory stress protocol with heart rate being measured throughout. After completing an acute psychological stress task, participants rated how stressed and physiologically aroused they felt (i.e., intensity) and whether they perceived the stress and physiological arousal as being helpful/unhelpful to performance (i.e., interpretation). Mastery imagery ability was assessed by questionnaire. Moderation analyses controlling for gender demonstrated that imagery ability moderated the relationship between heart rate reactivity and interpretation of stress (β = 0.015, p = .003) and perceived physiological arousal (β = 0.013, p = .004). Simple slope analysis indicated that in those with higher imagery ability, heart rate reactivity was associated with stress and arousal being perceived as more positive toward performance. Imagery ability did not moderate the relationship between heart rate reactivity and perceived stress intensity or physiological arousal intensity (p's > .05), but imagery ability did predict lower perceived stress intensity (β = −0.217, p < .001) and perceived physiological arousal intensity (β = −0.172, p < .001). Higher mastery imagery ability may possibly help individuals perceive responses to stress as more beneficial for performance and thus be an effective coping technique.

Published: November 2023

AbstractThe location patterns of new working spaces and the factors driving their emergence have been widely studied in Europe. However, research has mainly focused on specific countries and very local areas. We widen this perspective to a regional one and conduct a cross‐country study of the location patterns and determinants of today's main new working spaces, specifically coworking spaces that facilitate collaboration and knowledge sharing. Coworking spaces are traditionally associated in the literature with vibrant urban places, but they are also found in non‐metropolitan regions. Drawing on a unique data set of coworking space locations in four large European countries (Spain, France, Germany and Poland), we test how demographic, economic, structural, technological and accessibility‐related determinants affect the location of these spaces. We then investigate whether the identified determinants vary between metropolitan and non‐metropolitan and between countries, controlling for spatial effects.
A random graph growth model

AbstractA growing random graph is constructed by successively sampling without replacement an element from the pool of virtual vertices and edges. At start of the process, the pool contains virtual vertices and no edges. Each time a vertex is sampled and occupied, the edges linking the vertex to previously occupied vertices are added to the pool of virtual elements. We focus on the edge‐counting at times when the graph has occupied vertices. Two different Poisson limits are identified for and . For the bulk of the process, when , the scaled number of edges is shown to fluctuate about a deterministic curve, with fluctuations being of the order of and approximable by a Gaussian bridge.

Published: November 2023

Abstract
The study of component interactions in aeronautical engines is a key aspect to improve the aerodynamic, aeromechanical, and thermal performance and to reduce greenhouse gas and noise emissions. In this context, combustor systems (working with lean and premixed flames) generate pressure, velocity, and temperature fluctuations that interact with the turbine module producing combustor instability, performance degradation, and noise generation. A correct understanding of this interaction is thus required by the designers, especially with a view to introducing sustainable aviation fuel to achieve zero-emission aviation. This paper tackles this topic from a numerical and experimental point of view, focusing on off-design turbine conditions possibly encountered during an aero-engine mission. In detail, the effect of different stage loadings (obtained by keeping the stage pressure ratio and modifying the rotational speed) on engine-representative entropy waves evolving through the turbine stage is investigated. The combination of numerical and experimental results, that show a good agreement in terms of disturbance evolution within the stage, allows a deeper understanding of the flow field features that impact the stage aerodynamics and modify the secondary flow structures and the entropy wave transport, diffusion, and decay through the rotor. Moreover, the most loaded operating condition reveals the appearance of a rotating instability at the rotor tip that also interacts with the injected disturbance. Finally, the numerical results (coming from full annulus URANS computation with incoming disturbances) are further post-processed to extract indirect noise emissions at the different load conditions and to assess the additional loading on the rotor blade caused by the presence of the disturbance.

Abstract
The Independent Metering Valve-Controlled (IMVC) hydraulic cylinder system utilizes a twin spool structure to provide independent control of the load. This system overcomes the limitations of the coupling mechanical structure in traditional valve-controlled cylinder system with a single spool, while providing superior accuracy, flexibility, and energy efficiency. However, fault information representation is similar, and fault component identification is difficult for IMVC hydraulic cylinder system. This paper proposes a fault diagnosis method for IMVC hydraulic cylinder system which employs a deep neural network model utilizing 1DLCNN-ResNet to identify specific fault components via multi-sensor information fusion. The model captures global information using 1DLCNN and gains deeper insight with ResNet, enabling accurate diagnosis of detailed fault problems in specific components, such as pilot valves, main valves, displacement sensors, and hydraulic cylinder. A combination of simulation and experimentation was employed to discuss 16 detailed fault problems under different feature spaces. The results show that, detailed fault problems in specific component can be accurately diagnosed, particularly in the 9-dimensional feature space. The overall diagnostic accuracy of the system can reach 96.71%, and the detailed fault of one component can be effectively diagnosed which leads to a diagnostic coverage of 99%.
Investigation of the Temperature Influence on Electrohydraulic Valve Control and Presentation of a Novel Compensation Approach for Independent Metering Valve Systems

Published: November 2023

Abstract
In the design of valve control algorithms, the impact of the oil temperature on flow characteristic is often neglected. Generally, the flow mapping for the measured valve flow is considered to depend on only two factors, namely the displacement of the valve core and the pressure drop across control edges. The flow mapping and inverted flow mapping derived from this are implemented in the controller. However, previous investigation have shown that depending on the actual flow state within the valve, temperature variations can cause significant changes in flow rate, which in turn cause errors and increase control effort. Especially in mobile applications, systems are exposed to a wide range of external and internal temperature changes; hence, the impact and possibilities of temperature compensation are the focus of this work.
In order to demonstrate and quantify the impact of temperature variations on the valve flow characteristic, two common mobile valves, specifically spool and cartridge type, are measured. Control algorithms using flow mapping and inverse flow mapping for flow and pressure control of an independent metering valve system are implemented and analyzed regarding temperature sensitivity.
Secondly, four-dimensional models are proposed to describe the flow rate as a function of temperature, pressure drop, and spool displacement. These flow models are parametrized based on a computational efficient interpolation method considering the fluid flow state inside the valve. After that, the flow descriptions created can be used to refine the previous control strategy.
Compared to the control strategy without temperature compensation, the new control strategy not only maintains good dynamic characteristics, but also has more accurate flow rate respectively velocity control.

Published: November 2023

Abstract
Eco-friendly fluids in the hydraulic sector are becoming more and more relevant, under the current and future stringent environmental regulations by US EPA and European Committee. Biodegradable fluids have very interesting characteristics, and the literature starts reporting some contributions focused on components performance. The current article represents a contribution that brings the focus on the hydraulic poppet valves.
The article is based on a particular experimental technique that allows full optical insight on cavitation inception and development with simultaneous analysis of the steady flow rate, improving the classical technique of Oshima et Al.
Two market available eco-friendly fluids and a standard one are tested on a reference poppet valve layout. The experimental investigations are carried out by exploring the valve operation range in terms of pressure drop and poppet opening. The optical investigations are based on high-speed imaging, which allows to observe the behaviour of cavitating regions. The steady discharge flow coefficients are provided, and cavitation inception/development is characterized. The results related to the eco-friendly and to the standard fluids are compared, supporting the analysis of the influence of the new fluids on the discharge flow. The results on cavitation inception and development provide useful data for valve design and for validating three-dimensional models of cavitating flows.
