Programmatic Support for Peer Specialists that Serve Transition Age Youth Living with Serious Mental Illness: Perspectives of Program Managers from Two Southern California Counties
Authors: Magana Christopher , Gilmer Todd P. , Munson Michelle R. , Jones Nev , Burgos Jose Luis , Ojeda Victoria D. 
Published: June 2023

AbstractPeer Specialists (PS) often work in outpatient mental health programs serving transition age youth (TAY). This study examines program managers’ perspectives on efforts to strengthen PS’ professional development. In 2019, we interviewed program managers (n = 11) from two Southern California Counties employed by public outpatient mental health programs (n = 8) serving TAY and conducted thematic analyses. We present themes and illustrative quotes. PS’ roles are highly flexible; thus, PM support PS to strengthen skills to address organization-facing and client-facing responsibilities. PM addressed time management, documentation, PS integration into the organization, and workplace relationships. Trainings to better support clients included addressing cultural competency to serve LGBTQ TAY and racial/ethnic subgroups. Diverse supervision modalities address PS’ diverse needs. Supporting PS’ technical and administrative skills (e.g., planning, interpersonal communication skills) may aid their implementation of a complex role. Longitudinal research can examine the impact of organizational supports on PS’ job satisfaction, career trajectories, and TAY clients’ engagement with services.
Assessing Psychopathic Traits Early in Development: Testing Potential Associations with Social, Behavioral, and Affective Factors

Published: June 2023

AbstractThe Child Problematic Traits Inventory (CPTI) enables the assessment of psychopathy dimensions as early as age three. The current study employs a multi-informant approach (i.e., fathers, mothers, and teachers) to further investigate the unique associations between psychopathy dimensions, as measured by the CPTI, with theoretically relevant constructs of interest, such as conduct problems, oppositionality, empathy, and social relations, in early childhood (N = 1283, M age = 6.35). Although associations with conduct, aggressive, and oppositional behaviours differed in strength, our findings supported the importance of all psychopathy dimensions in predicting behavioral problems. Our findings also suggested a unique association of the callous-unemotional dimension with affective empathy. Furthermore, stronger associations were identified between the callous-unemotional and impulsive need for stimulation dimensions with social problems (e.g., peer and family relations) compared to the grandiose-deceitful dimension. Current findings can inform prevention and intervention efforts aiming to alter the development of psychopathic traits.
Unprecedented rainfall index for reducing fatalities caused by sediment-related disasters
Authors: Kosugi Ken′ichirou 
Published: June 2023

AbstractThis study evaluated effectiveness of the unprecedented rainfall index, TP, proposed by Kosugi (2022) in achieving appropriate evacuation actions by municipalities and residents for reducing victims caused by rainfall-induced landslides and debris flows. TP is defined as the time stamp representing the situation that “current rainfall is the largest since TP”; namely, if we go back to time before TP, the rainfall at the current time is of a magnitude that has been experienced in the past (i.e., the situation is within the historical range) in every evaluation criterion used in analyses. In other words, the rainfall at the current time is of a magnitude never experienced in the period from TP through the present for at least one criterion. TP was computed for all disasters that caused death and missing of people in Japan in 2021: the Atami, Unzen, and Okaya disasters. In every disaster, at the time of the landslide and debris flow occurrences, TP reached the beginning of rainfall record, indicating that the rainfall reached a magnitude never experienced in the past. Based on these results, it was confirmed that (1) TP time series has a large potential to reduce the normalcy bias in all 3 disasters studied, (2) for evaluating anomaly in rainfall, rainfall features should be analyzed based on various evaluation criteria, and (3) the time of past land alteration at an individual location, such as an occurrence time of historical storm event and a construction time of embankment slope, might be set as a TP threshold.
Efficiency measurement in the tendering of road surface renewal contracts

Published: June 2023

AbstractThe problem of slow productivity growth in the road construction (and wider construction) industry is well known. The present paper suggests a means for efficiency analysis in one part of this industry, namely road surface renewal in Sweden, built upon the application of Stochastic Frontier Analysis (SFA) techniques. The paper is novel in that it focuses on project level rather than firm or contractor level performance and takes the perspective of the inefficiency that may result from the way the contracts are specified by the highway agency’s pavement engineers (client side). We compare 233 renewal contracts tendered over a four-year period via the estimation of a cost frontier, with controls for heterogeneity between projects. Our results produce first estimates that expose substantive differences in the relative efficiency performance of different engineers within the Swedish highways procurement organisation (Trafikverket); with indicative savings of around €40 m out of a total road renewals budget in Sweden of €200 m. We also find substantial economies of scale that could, in principle, point to further cost savings if road renewal projects can be packaged up as larger projects. These client-side savings represent potentially important sources of savings in addition to those that can be achieved through the pressure of competitive tendering on the supplier side. The paper therefore illustrates how disaggregate analysis of project level information can readily be used for revealing important information about how best to frame the procurement process and thus deliver productivity and unit cost improvements over time.
DOVE: Learning Deformable 3D Objects by Watching Videos
Authors: Wu Shangzhe , Jakab Tomas , Rupprecht Christian , Vedaldi Andrea 
Published: June 2023

AbstractLearning deformable 3D objects from 2D images is often an ill-posed problem. Existing methods rely on explicit supervision to establish multi-view correspondences, such as template shape models and keypoint annotations, which restricts their applicability on objects “in the wild”. A more natural way of establishing correspondences is by watching videos of objects moving around. In this paper, we present DOVE, a method that learns textured 3D models of deformable object categories from monocular videos available online, without keypoint, viewpoint or template shape supervision. By resolving symmetry-induced pose ambiguities and leveraging temporal correspondences in videos, the model automatically learns to factor out 3D shape, articulated pose and texture from each individual RGB frame, and is ready for single-image inference at test time. In the experiments, we show that existing methods fail to learn sensible 3D shapes without additional keypoint or template supervision, whereas our method produces temporally consistent 3D models, which can be animated and rendered from arbitrary viewpoints.

Published: June 2023

AbstractThis study investigated the mechanism of neurotrophin-3 (NT-3) in promoting spinal cord injury repair through the transforming growth factor-beta (TGF-β) signaling pathway. A mouse model of spinal cord injury was established. Forty C57BL/6J mice were randomized into model, NT-3, NT-3 + TGF-β1 and NT-3 + LY364947 groups. The Basso–Beattie–Bresnahan (BBB) scores of the NT-3 and NT-3 + LY364947 groups were significantly higher than the model group. The BBB score of the NT-3 + TGF-β1 group was significantly lower than NT-3 group. Hematoxylin-eosin staining and transmission electron microscopy showed reduction in myelin sheath injury, more myelinated nerve fibers in the middle section of the catheter, and relatively higher density and more neatly arranged regenerated axons in the NT-3 and NT-3 + LY364947 groups compared with the model and NT-3 + TGF-β1 groups. Immunofluorescence, TUNEL and Western blot analysis showed that compared with model group, the NEUN expression increased, and the apoptosis and Col IV, LN, CSPG, tenascin-C, Sema 3 A, EphB2 and Smad2/3 protein expression decreased significantly in the NT-3 and NT-3 + LY364947 groups; the condition was reversed in the NT-3 + TGF-β1 group compared with the NT-3 group. NT-3 combined with TGF-β signaling pathway promotes astrocyte differentiation, reduces axon regeneration inhibitory molecules, apoptosis and glial scar formation, promotes axon regeneration, and improves spinal cord injury.

AbstractInfrared photovoltaic cells (IRPCs) have attracted considerable attention for potential applications in wireless optical power transfer (WOPT) systems. As an efficient fiber-integrated WOPT system typically uses a 1550 nm laser beam, it is essential to tune the peak conversion efficiency of IRPCs to this wavelength. However, IRPCs based on lead sulfide (PbS) colloidal quantum dots (CQDs) with an excitonic peak of 1550 nm exhibit low short circuit current (Jsc) due to insufficient absorption under monochromatic light illumination. Here, we propose comprehensive optical engineering to optimize the device structure of IRPCs based on PbS CQDs, for 1550 nm WOPT systems. The absorption by the device is enhanced by improving the transmittance of tin-doped indium oxide (ITO) in the infrared region and by utilizing the optical resonance effect in the device. Therefore, the optimized device exhibited a high short circuit current density of 37.65 mA/cm2 under 1 sun (AM 1.5G) solar illumination and 11.91 mA/cm2 under 1550 nm illumination 17.3 mW/cm2. Furthermore, the champion device achieved a record high power conversion efficiency (PCE) of 7.17% under 1 sun illumination and 10.29% under 1550 nm illumination. The PbS CQDs IRPCs under 1550 nm illumination can even light up a liquid crystal display (LCD), demonstrating application prospects in the future.

A Daily Breathing Practice Bolsters Girls’ Prosocial Behavior and Third and Fourth Graders’ Supportive Peer Relationships: A Randomized Controlled Trial
Authors: von Salisch Maria , Voltmer Katharina 
Published: June 2023

Abstract
Objectives
In order to promote mindfulness in primary school, the Breathing Break Intervention was developed. This collection of short daily breath-based mindfulness practices was introduced to 15 teachers who delivered them up to 3 times a day to their students.

Method
In a randomized controlled trial, 146 third and fourth graders (49% female) either received the intervention (n = 81) or participated in the active wait list control group (n = 65). Students were asked to nominate prosocial peers and to report on supportive peer relationships in their classrooms before (pretest) and after (posttest) the 9 weeks of the Breathing Break Intervention, and in a follow-up 5 months later.

Results
Mixed multilevel models indicated a group × sex × posttest interaction (t(211) = 2.64, p < 0.01) suggesting that girls in the intervention group were rated to be more prosocial by their peers at posttest than at pretest and than girls in the active control group when children’s age and parents’ education were accounted for. Supportive peer relationships in the active control group deteriorated between pretest and posttest, which occurred immediately before the second school lockdown due to the COVID-19 pandemic, whereas they remained the same in the intervention group (t(223) = 2.56, p < 0.05). Both effects were not maintained at follow-up, probably due to children’s irregular school attendance during the lockdown.

Conclusions
Introducing a short daily breathing practice in primary school classrooms seems to be effective in maintaining supportive peer relationships and in stimulating girls’ prosocial behavior.

Authors: Reinhardt Lydia , Steeb Theresa , Mifka Anika , Berking Carola , Meier Friedegund ,   on behalf of the German Skin Cancer Council
Published: June 2023

AbstractIn 2008, a nationwide skin cancer screening (SCS) program was implemented in Germany. However, participation rates remain low. YouTube videos on SCS might educate eligible persons to undergo SCS. Until now, no scientific evaluation of the quality of videos available for German-speaking persons eligible for SCS has been performed. Here, we identified and evaluated videos on SCS provided on YouTube. YouTube was searched in May 2022 for German terms related to SCS. Two authors evaluated the videos of the first three pages that met the predefined eligibility criteria. The quality of the videos´ information was evaluated using DISCERN and the Global Quality Scale (GQS). The understandability and actionability were assessed with the Patient Education Materials Assessment Tool (PEMAT). The reliability was assessed with the Journal of American Medical Association (JAMA) score. Subgroup differences were identified by the Kruskal–Wallis test. Overall, 38 videos were included in the evaluation. Most videos were provided by health professionals (clinics and practices). The average scores (mean (SD)) for the individual tools were as follows: DISCERN 3.1/5 points (± 0.52), GQS 3.72/5 points (± 0.7), understandability 64,27% (± 13.53%), actionability 58.22% (± 15.18%), JAMA 37.17% (± 18.94%). These results indicate a mediocre to good understandability, a mediocre quality and actionability, and a low reliability. Videos that were assessed as useful were of significantly better quality. An improvement of freely available informational videos on SCS, especially with regard to the reliability criteria, is urgently needed.
The single flapping rotor: detailed physical explanations
Authors: Geißler W. 
Published: June 2023

AbstractA motor-driven helicopter rotor generates a reaction torque. This torque would accelerate the airframe of the helicopter about the yaw axis opposite to the rotor rotation if no measures are taken to compensate it. In the early days of helicopter development, a diversity of measures was considered: Henrich Focke has discussed these different measures. Not well known is a torque compensation measure which is restricted to only one main rotor, thus skipping the tail rotor or any additional rotor as well. This principle is worth looking into the details of the physical mechanism involved. The German scientist Prof. Hans-Georg Küssner of the AVA-Göttingen, Germany (Aerodynamic Research Institute with heads at this time: L. Prandtl and A. Betz) was the first to study the method successfully. He constructed a wind tunnel model and showed that the reaction torque could indeed be completely compensated. The present author has reviewed Küssner’s experimental data and could show that numerical calculations are in good correspondence with the measured results. In the present paper, the details of the method to compensate the reaction torque will be discussed. Corresponding numerical data will be presented taking into account Navier–Stokes calculations on rotor blade sections. Blade element theory will then be applied and combined with the Navier–Stokes data. Calculated forces and moments of a complete four-bladed helicopter rotor will be presented.
Reconceptualizing coastal fisheries conflicts: a Swedish case study
Authors: Arias Schreiber Milena , Gillette Maris B. 
Published: June 2023

AbstractFisheries conflicts have often been interpreted as arising from disputes over access to fish. Competition for fishing stocks among resource users (human and non-human) and fisheries managers’ attempts to control access to fish are depicted as main causes of conflicts. From this perspective, rampant environmental degradation, climate change, and a growing human population will only exacerbate tensions in fisheries. Yet is it only competition for fish that drives conflicts? Research on coastal and small-scale fishers has shown that they fish not only to achieve economic (material) goals but also to fulfill social and immaterial needs. Drawing on Burton’s theory of human needs, in this exploratory study, we consider how attention to coastal fishers’ material and immaterial needs might illuminate aspects of fisheries disagreements that are missed when conflicts are theorized solely in terms of material interests. Our data comes from 46 voluntary written statements provided at the end of a self-administered survey on the fishing sector sent to all holders of a Swedish commercial fishing license in June 2019. Results suggest that coastal fisheries conflicts are not solely about access to fish but also about social and emotional needs for respect, identity, belongingness, and status. In particular, fishers’ demands for actions to boost the number of coastal fishers – and subsequently the number of potential competitors – challenges the narrowly emphasis on materiality. We argue that an overemphasis on material needs may divert attention away from other causes of tension and thus prevent actions that could alleviate or mitigate fisheries conflicts.

Published: June 2023

AbstractGreenhouse gas emissions are caused by human activities, one of which is the manufacturing process, which is the main driver of global warming. The machining process is a common practice in sectors such as aerospace and automotive. Based on the latter, this research focuses on understanding and testing an alternative way to make an economically sustainable machining process. This study reports on the performance of tool life analysis under dry settings, and the cutting speed calculation considers machining and tooling costs. Developing a design of the experiment established the power demand equation, which is part of the energy model presented in this research, and it also helps to understand the carbon dioxide emissions to the environment before starting the milling process. Based on the results, the tool life evaluation shows the longest working time under good tool conditions with a measured surface roughness of less than 0.6 μm. The energy model shows the alternative to improve energy consumption and CO2 emissions by 0.11 kWh and 0.055 kg CO2, respectively, which is essential to understand the challenge of reducing the manufacturing footprint.
Lessons Learned in Qatar: The Role of the Netherlands and Its Businesses in Addressing Human Rights Abuses in Mega-Sporting Events
Authors: Heerdt Daniela , Roorda Lucas 
Published: June 2023

AbstractMega-sporting events (MSEs) can have a negative impact on human rights throughout their lifecycle, from the bidding stage, over to the planning and preparation stage, the delivery of the event, and also as part of their legacy after the event has concluded. They can be linked to land grabbing, forced evictions, forced labour and many other human rights abuses. The problem is that only a very few of these cases are actually addressed in the sense that rights-holders receive an effective remedy and those responsible for the abuse are held to account. MSEs are jointly organized and staged by public, private, national, and international actors, which each contribute in different ways to the associated human rights impact. Rather than looking at the responsibility of those actors directly involved in organizing and staging the event, this article looks at the responsibility of the participating actors of states that are represented at the event, namely businesses and sports bodies, using the Netherlands and the 2022 FIFA World Cup in Qatar as the guiding example. The central questions it tries to explore based on lessons learned and opportunities missed in Qatar are how such actors are connected to adverse human rights impacts associated with MSEs, which responsibilities under the human rights framework flow from those connections, and how participating states should then ensure that businesses live up to their responsibilities.
Eliciting policy-relevant stated preference values for water quality: An application to New Zealand
Authors: Walsh Patrick J. , Guignet Dennis , Booth Pamela 
Published: June 2023

AbstractGovernments need tools to analyze trade-offs for freshwater policy, yet valuation estimates from the literature can be difficult to deploy in a policy setting. Obstacles to benefit transfer include (i) difficulties in scaling up local estimates, (ii) water quality attributes that cannot be linked to policy, and (iii) surveys positing large, unrealistic water quality changes. Focusing on freshwater rivers and streams in New Zealand, we develop and implement a nationwide discrete choice stated preference study aimed at future benefit transfer. The stated provision mechanism and environmental commodity being valued are specified at the regional council level, which is the administrative unit for policy implementation. The survey is administered on a national scale with three attributes – nutrients, water clarity, and E. coli levels – which were chosen to align with government policy levers and salience to the public. Estimation results demonstrate positive and significant willingness to pay values for improvements in each attribute, with magnitudes that are comparable to a recent referendum vote on a water quality tax. To illustrate the utility of our study, we apply the results to a recent policy analyzed by New Zealand’s Ministry for the Environment and estimate nationwide annual benefits of NZ $115 million ($77 million USD).
Squamarina subcetrarioides comb. & stat. nov. (Stereocaulaceae), a separate species from the type species of Squamarina
Authors: Zhang Yanyun , Wang Lun , Wang Xinyu , Printzen Christian , Timdal Einar , Wang Lisong 
Published: June 2023

AbstractThe type species of Squamarina has two varieties, S. gypsacea var. gypsacea and S. gypsacea var. subcetrarioides. In this study, a phylogenetic and taxonomic analysis of these two varieties shows that S. var. subcetrarioides merits treatment as a species separate from S. gypsacea. Therefore, we raise this variety to species level as S. subcetrarioides (Zahlbr.) Y. Y. Zhang. Squamarina subcetrarioides is phylogenetically not closely related to S. gypsacea and differs from that species in the thallus forming rosettes when young, later becoming cracked and irregular in outline, and consisting of numerous small squamules.
