Authors: Frisendahl Nathalie , Karlsson Patrik , Ek Stina , Franzén Erika , Boström Anne-Marie , Welmer Anna-Karin 
Published: September 2024

Abstract
Purpose
There is a need for further research on older adults’ experiences of fall risk screening to improve health communication strategies. The purpose of this study was to describe and explore older adults’ experiences of being screened for risk of an injurious fall, using the first-time injurious falls (FIF) screening tool.

Methods
A qualitative study with five focus group interviews was carried out including 17 older adults (11 women and six men, with a mean age of 77.4 years) who were recruited from two primary healthcare rehabilitation clinics in Sweden. Data were analyzed using reflexive thematic analysis.

Results
The analysis generated one overarching theme, “Screening for fall risk promotes engagement by raising older adults’ awareness of their own abilities”, and four categories; “Screening may motivate to take action but can also create a false sense of security”, “Self-sufficiency is affected by the screening result and level of control over the environment”, “Easy-to-perform and helps to facilitate a discussion with the healthcare professional” and “Ideas of how FIF tool could be used in healthcare”.

Conclusion
Older adults considered screening for fall risk to be meaningful insofar as it raises awareness of their own abilities and motivates them to prevent falls. On the other hand, a low fall risk could create a false sense of security, and lack of control over environmental factors related to fall risk could negatively impact their sense of self-sufficiency. They emphasized the need to receive support from healthcare providers and to be involved in care decisions if the screening indicates a high fall risk.
Digitalization in Italian SMEs: the transformation of marketing channels
Authors: Martinelli Elisa Martina , Tunisini Annalisa 
Published: September 2024

AbstractThe evolution of marketing channel management and the integration of digital technologies in the overall marketing architecture have been deeply examined in the SME literature. Even if in academia the opportunities of digital in terms of performance, growth, and competitiveness are well recognized, in practice, SMEs are not always ready to fully exploit the potential of new technologies, reshaping their channels’ structure and strategies. In this paper, we display insights into the transformation and management of marketing channels for Italian manufacturing medium-sized enterprises. The study explores if and how “Made in Italy” companies are introducing digital channels in their market strategy, aiming at an omnichannel management perspective. We conduct a two-stage research design involving manufacturing medium-sized enterprises acting in the typical “Made in Italy” sectors: a Grounded Delphi Method with semi-structured interviews and the collection of data by a survey. We contribute to extending prior literature by presenting the enablers and barriers of specific marketing channels in the overall architecture and the main reasons for improving an omnichannel perspective in the perspective of the near future. In particular, the research identifies that Made in Italy medium-sized enterprises rest on decisions about adopting and managing specific channels and developing an omnichannel perspective on firm-specific and owner-managerial factors, while resource-related and environmental factors can be overcome, in particular, thanks to new partners. Based on this analysis, we then recommend specific research avenues to stimulate and advance further investigations.
Accuracy of screw placement during vertebral body tethering using fluoroscopic guidance and anatomic landmarks

Published: September 2024

Abstract

Purpose
To determine the accuracy of screw placement using fluoroscopy and anatomic landmarks during vertebral body tethering (VBT) surgery.

Methods
Ten patients with 73 VBT screws were converted to posterior spinal fusion (PSF) after continued curve progression. The positions of each VBT screw were analyzed using intraoperative computed tomography (CT) scans performed for image guidance during VBT. Differences for screws placed using an open versus thoracoscopic approach were noted for the screw position in each vertebra, distance from the spinal canal, unicortical versus bicortical placement, the distance of screw tips from the thoracic aorta, and impingement of screws on adjacent rib heads.

Results
Seventy three (73) screws in ten (10) patients were available for analysis. Only 21% of screws were placed traversing the middle one-third of the vertebral body, without spinal canal penetration, with the distal tip placed unicortically or bicortically as planned, and without touching the thoracic aorta. The rates of non-ideal screw placement were not significantly different for screws placed via thoracoscopic versus open approaches. Five (5) screws (6.8%) penetrated the spinal canal 1–2 mm, but without known clinical sequelae.

Conclusion
The majority of VBT screws available for analysis were placed in non-ideal positions, suggesting that accurate screw placement using intraoperative fluoroscopy and anatomic landmarks can be challenging, but without adverse clinical consequences.

AbstractMyxobacteria are non-photosynthetic bacteria distinguished among prokaryotes by a multicellular stage in their life cycle known as fruiting bodies that are formed in response to nutrient deprivation and stimulated by light. Here, we report an entrained, rhythmic pattern of Myxococcus macrosporus fruiting bodies, forming consistently spaced concentric rings when grown in the dark. Light exposure disrupts this rhythmic phenotype, resulting in a sporadic arrangement and reduced fruiting-body count. M. macrosporus genome encodes a red-light photoreceptor, a bacteriophytochrome (BphP), previously shown to affect the fruiting-body formation in the related myxobacterium Stigmatella aurantiaca. Similarly, the formation of M. macrosporus fruiting bodies is also impacted by the exposure to BphP—specific wavelengths of light. RNA-Seq analysis of M. macrosporus revealed constitutive expression of the bphP gene. Phytochromes, as light-regulated enzymes, control many aspects of plant development including photomorphogenesis. They are intrinsically correlated to circadian clock proteins, impacting the overall light-mediated entrainment of the circadian clock. However, this functional relationship remains unexplored in non-photosynthetic prokaryotes. Genomic analysis unveiled the presence of multiple homologs of cyanobacterial core oscillatory gene, kaiC, in various myxobacteria, including M. macrosporus, S. aurantiaca and M. xanthus. RNA-Seq analysis verified the expression of all kaiC homologs in M. macrosporus and the closely related M. xanthus, which lacks bphP genes. Overall, this study unravels the rhythmic growth pattern during M. macrosporus development, governed by environmental factors such as light and nutrients. In addition, myxobacteria may have a time-measuring mechanism resembling the cyanobacterial circadian clock that links the photoreceptor (BphP) function to the observed rhythmic behavior.

Published: September 2024

AbstractTo solve the problem of mobile robots needing to adjust their pose for accurate operation after reaching the target point in the indoor environment, a localization method based on scene modeling and recognition has been designed. Firstly, the offline scene model is created by both handcrafted feature and semantic feature. Then, the scene recognition and location calculation are performed online based on the offline scene model. To improve the accuracy of recognition and location calculation, this paper proposes a method that integrates both semantic features matching and handcrafted features matching. Based on the results of scene recognition, the accurate location is obtained through metric calculation with 3D information. The experimental results show that the accuracy of scene recognition is over 90%, and the average localization error is less than 1 meter. Experimental results demonstrate that the localization has a better performance after using the proposed improved method.
A probabilistic approach for the levelized cost of energy of floating offshore wind farms
Authors: Amlashi Hadi , Baniotopoulos Charalampos 
Published: September 2024

AbstractThis paper aims to analyze the levelized cost of energy (LCOE) of floating offshore wind farms from a probabilistic point of view. Understanding and addressing the uncertainty associated with the main parameters that influence the wind energy generated by a wind farm during its lifetime is crucial for the economic evaluation of offshore wind energy in the broader energy landscape. The methodology for probabilistic assessment of LCOE is introduced, and the uncertainty in input parameters are discussed. In a base case study, an assumed Floating Offshore Wind Farm (FOWT) consisting of 250 5-MW wind turbines is considered. The use of bias and randomness in key random variables is discussed and studied in detail. Results indicate that LCOE estimates of 15 EURc/kWh for offshore wind turbines are achievable with reasonable confidence, while estimates of 5 EURc/kWh require careful consideration of uncertainty in the wind farm’s parameters. The feasibility analysis showed that techno-economic parameters are more influenced by wind characteristics and efficient use of wind turbines than by the cost of the wind farm. This paper provides general guidance on how to carry out early-stage techno-economic analysis of FOWFs.
Experimental study on corrosion inhibition of mild steel using Mukia maderaspatana leaves extract as green inhibitor

Published: September 2024

AbstractIn this work, investigations were conducted into the adsorption behaviour and inhibitory effect of Mukia maderaspatana leaves extract on the corrosion of mild steel in 1.5M HCl solution at several temperatures. The techniques included chemical methods (weight loss measurements), surface analysis (SEM, FESEM) and solution analysis (UV–visible spectrophotometric, ICP-MS) techniques. The examination of the data revealed that the efficiency of inhibition rose as the inhibitor's concentration increased and fell as the temperature increased. At 30 degrees Celsius, the concentration of inhibitor resulted in an increase in corrosion inhibition efficiency, reaching 99.02% efficiency at 8% concentration. The physical adsorption of the inhibitor on the metal surface was demonstrated by the adsorption free energy of the plant extract on mild steel. The conclusions above are supported by data from examinations of Scanning Electron Microscopy, FESEM, UV–visible and Fourier transform infrared spectrophotometry.
The Effects of Immigration Policy on Business Creation: A Study of the Effects of 287(g) Mandates
Authors: Shrestha Dipesh , Kostandini Genti 
Published: September 2024

AbstractThis study examines the impact of county-level immigration enforcement of section 287(g) mandates on the number of businesses in the United States. Using the difference-in-differences model, we find that the implementation of 287(g) negatively affected the total number of businesses. We find that counties with 287(g) agreements experienced a 6 percent decrease in the total number of businesses per 1000 county population and this negative effect appeared to be more prominent in businesses with a higher number of employees. Our findings shed light on the complex impacts of immigration policies on businesses, especially those reliant on immigrant labor.
A sensitivity study on the starting simulations of turbojet engines

Published: September 2024

AbstractGas turbine engine starting models require a lot of calibration to represent reality with acceptable accuracy due to the lack of high-quality component rig data in the sub-idle region. A detailed sensitivity study is presented in this paper to guide such calibration efforts. A thermodynamic component-matching type transient model of a single-spool turbojet engine with shaft and heat-soakage dynamics is employed for this purpose. Turbomachinery component maps are extended to sub-idle using an in-house map smoothing tool and the strategies presented by Kurzke recently. These extension strategies make use of the correlations hidden in the already available regions of the maps and ensure physical consistency. However, they contain some uncertainty, even when an experimentally obtained zero-speed line is available. Combustor sub-idle efficiency, stability limits, and delay are taken from the literature. Due to the chaotic nature of a combustor in the sub-idle region, a precise prediction of the combustor efficiency seems impossible. Effects of uncertainties related to sub-idle turbomachinery map extensions, burner efficiency, and heat soakage are investigated in this paper. Two popular fuel control strategies are employed and compared to see how controls deal with these uncertainties. It is concluded that turbomachinery torque characteristics and turbine capacities are the most important parameters when calibrating a starting model with a control based on rotational acceleration while burner efficiency and heat soakage are added on top of these with a control based on fuel flow rate.
Balancing the nexus of beef sustainability: a best–worst scaling approach to inform policy decisions
Authors: Osman Eliyasu Y. , Schroeder Ted C. , Lancaster Phillip A. , White Brad J. 
Published: September 2024

AbstractThe beef industry is facing increasing pressure to adopt sustainable practices, driven by environmental, economic, and social concerns. Designing effective policies that satisfy industry demands while aligning with public interests is a complex challenge. Using a nationally representative survey of 3,001 U.S. residents, we employ a best–worst scaling approach to assess preferences for nine beef sustainability policies. Results reveal consumers prioritize affordability of beef products and welfare of cattle as most important sustainability policies. Conversely, policies addressing greenhouse gas emissions from cattle production are least important, with less than 6% of respondents preferring them.
Recreating an Amazonian Ancestral Biodesign Technique
Authors: Bandoni Andrea , Cohen Lauro , Cotta Marcela , Paoliello Carla 
Published: September 2024

Abstract
This study investigates an ancestral Biodesign technique associated with the fruits of the Amazonian tree Crescentia cujete. For centuries, Amazonian artisans have transformed these fruits into objects named cuias, which serve mainly as containers. Despite the continued practice of cuias production, a specific shaping technique discovered in historical accounts remains unknown and unused by contemporary artisans. The paper reports the recreation of this technique considering the ancestral ethos underpinning these traditions. A mixed-method approach has combined historical and museum research, direct interaction with trees in a bioeconomy context, and participatory observation of traditional artisans’ production. The findings reveal the ancient practice of “Growing Design” with that tree and other practices that resonate with Biodesign, establishing a connection between this field and indigenous knowledge. This study highlights the underappreciation of indigenous objects and techniques, emphasizing the potential that emerges from understanding the alignment of certain ancestral wisdom with Biodesign principles, such as amplifying indigenous heritage and opening new possibilities in design.
An Evidence Gap Map of Experience-based Evidence of Health Resource Allocation in Disaster and Humanitarian Settings
Authors: Horn Zachary B , Ranse Jamie , Marshall Andrea P 
Published: September 2024

Abstract

Objective
The aim of this review is to identify, evaluate, and graphically display gaps in the literature related to scarce health resource allocation in humanitarian aid settings.

Methods
A systematic search strategy was utilized in MEDLINE (via Ovid), Scopus, EMBASE, CINAHL Complete, and ProQuest Central. Articles were reviewed by 2 reviewers with a third reviewer remedying any screening conflicts. Articles meeting inclusion criteria underwent data extraction to facilitate evaluation of the scope, nature, and quality of experience-based evidence for health resource allocation in humanitarian settings. Finally, articles were mapped on a matrix to display evidence graphically.

Results
The search strategy identified 6093 individual sources, leaving 4000 for screening after removal of duplicates. Following full-text screening, 12 sources were included. Mapping extracted data according to surge capacity domains demonstrated that all 4 domains were reflected most of all the staff domain. Much of the identified data was presented without adhering to a clear structure or nomenclature. Finally, the mapping suggested potential incompleteness of surge capacity constructs in humanitarian response settings.

Conclusions
Through this review, we identified a gap in evidence available to address challenges associated with scarce resource allocation in humanitarian settings. In addition to presenting the distribution of existing literature, the review demonstrated the relevance of surge capacity and resource allocation principles underpinning the developed framework.
Impact and learner perspectives of a spaced-education platform to assess hand hygiene auditor competency
Authors: Vaughan-Malloy Ana M. , Lehane Renée , Wells Mary M. , Sandora Thomas J. 
Published: September 2024

AbstractObjective:To ensure whether spaced education, which increases long-term knowledge retention, could be integrated into auditor competency assessment.Design:Quality improvement project.Setting:Academic, freestanding children’s hospital.Participants:Hand hygiene (HH) auditors.Intervention:We enrolled trained HH auditors in an online spaced-education platform to assess mastery of knowledge, delivering 46 unique questions at spaced intervals followed by rationale; we retired questions after 3 correct answers. An e-mailed 10-item survey gauged participant satisfaction with the program. The Wilcoxon signed-rank test was used to compare change in median knowledge score from first to final attempt.Results:A total of 12,120 questions were attempted by 126 auditors, and 49 (39%) completed the entire course. Median knowledge score increased significantly by 10.5 percentage points (IQR 4–15) between first and final attempts (P < 0.001). Thirty auditors (27%) responded to the survey. The majority agreed the number and complexity of questions were appropriate (57% and 67%, respectively). Eighty-seven percent reported the platform easy to navigate, and 77% agreed adequate time was provided for completion. Free-text suggestions included delivering fewer questions at a narrower spacing interval over a shorter time frame because of competing work demands.Conclusions:Auditor knowledge of HH indications and technique is critical to ensuring data validity. A spaced-education competency program improved HH auditor knowledge in the short term. Completion rate was low, and some participants expressed a desire for fewer questions over a shorter time frame. This study offers insight into ways to optimize spaced education as a potential tool for HH competency assessment.
Motivation from Joseph Ratzinger’s Eschatological Realism for Protecting Humanity’s Future
Authors: Wygnanski Piotr 
Published: September 2024

AbstractThis article outlines one way in which Joseph Ratzinger’s eschatology could contribute to reducing the risk humanity now creates to its own survival. Studies of ‘Existential Risk’ warn that hazards arising from Artificial Intelligence, Nuclear Weapons, Climate Change, and Engineered Pathogens require mitigation to safeguard the future of the human race from a calamitous end. Preventative measures, however, entail sacrifice, and there is no shortage of resistance to regulation of behaviours and technological development. Ethics of empathy, utility, and duties reach breaking point when stretched to overcome the temporal and moral gap between present agency and future well-being.This article proposes that Ratzinger’s theology of history and commitment to eschatological realism offers an intertwined double benefit: his warning about the danger of conflating hope in God’s Kingdom with hope in a future world humanity could perfect for itself opens up the uniquely rich ground of a trans-historical hope in Jesus Christ, in which an impactful relationship of love for humanity’s future can put down roots today.
Persistent unilateral action
Authors: Foster David 
Published: September 2024

Abstract
Many believe that weaker legal constraints make unilateral action easier to reverse than legislation. Yet in some cases, unilateralism survives a successor's determined opposition. I argue that legislative persistence and unilateral transience may arise not only from differences in legal status but also from a selection effect: unilateralism and subsequent rescission can both stem from weak underlying policy-demanding groups. But if unilateralism itself alters the landscape of group power through policy feedback effects, it can survive a purportedly opposed new president. An example is the Trump Administration's failure to depart from the Obama Justice Department's lax stance on cannabis. Weak constituents’ policy demands may thus need to rely on a sympathetic president's unilateral action to begin a feedback loop, subsequently softening opposition. This paper therefore identifies unilateral action as a key tool for shifting policy in an enduring way, explaining its success or failure in terms of interest group power.

AbstractThe Chinese Loess Plateau (CLP), recognized as the world's largest loess plateau, has been a subject of ongoing debate regarding the continuity of its sedimentary loess sequence due to its intricate depositional environment. In this study, we conducted dating on a 9.8-m-long Malan loess core obtained from the Sanmen Gorge in the southern CLP using optically stimulated luminescence (OSL). The OSL dates indicate loess deposition between 52.4 and 11.3 ka, with no apparent hiatus on a millennial scale, and a sedimentation rate (SR) exhibiting six distinct episodes. Additionally, a comprehensive review of 613 OSL ages from 18 sections at 14 sites across the CLP was conducted. The results reveal loess deposition at most sites shows no apparent hiatus on a millennial scale over the past 60 ka, except for two specific locations. High SR episodes during Marine Isotope Stage (MIS) 3 across the CLP were attributed to heightened dust emissions from the source region and an enhanced dust deposition efficiency, while MIS 2 deposits were influenced by an intensified East Asian winter monsoon. Low SR episodes during MIS 1 at most sites were likely associated with reduced atmospheric transportation and pedogenesis. Spatially heterogeneous SR variations across the CLP might be influenced by local depositional environments.
