Spinoza on Ingenium and Exemplarity: Some Consequences for Educational Theory
Authors: Dahlbeck Johan 
Published: July 2020

AbstractThis article turns to the neglected pedagogical concept of ingenium in order to address some shortcomings of the admiration–emulation model of Linda Zabzebski’s influential exemplarist moral theory. I will start by introducing the problem of the admiration-emulation model by way of a fictional example. I will then briefly outline the concept of ingenium such as it appears in a Renaissance context, looking particularly at the pedagogical writings of Juan Luis Vives (1492/3–1540). This will set the stage for the next part, looking at how early modern philosopher Benedict Spinoza (1632–1677) adopts a Vivesian notion of ingenium, adjusting it so as to fit into the setting of his political theory. Next, I will turn to Spinoza’s use of the concept of ingenium in relation to his portrayal of exemplary persons, offering a pedagogical model of moral exemplarism that can counter some of the perceived problems of the admiration–emulation model as it highlights the necessary fallibility of efficient exemplars as well as acknowledges the socio-political dimension of emotions. Finally, I will lay out some preliminary consequences for educational theory, hoping to offer a way of reconciling moral exemplarism with a more realistic pedagogical and psychological framework.

Abstract
Purpose of Review
The purpose of this review is to summarize the current knowledge on sexual desire expressions, sexual orientation, and identity in understudied groups inside the LGBT+ community.

Recent Findings
Sexual desire and related problems have unique expressions in LGBT+ people which influence their sexual health. Emerging sex-positive approaches might be powerful and prominent tools to provide support and education on behalf of safer sex practices and marginalized sexualities. The importance of deepening LGBT+ sexualities and relationships, not only in lesbian women and gay men but also in all the other shades of the rainbow (bisexual, transgender, asexual, fluid, and non-binary/genderqueer identities), is strongly highlighted.

Summary
A lack of literature regarding sexual desire in LGBT+ people is reported. Results are controversial and research is still limited on this topic, with little information available about sexual and health needs of sexual minorities beyond gay and lesbian people.
Eight items of the ruminative response scale are sufficient to measure weekly within-person variation in rumination
Authors: Brose Annette , Raedt Rudi De , Vanderhasselt Marie-Anne 
Published: July 2020

AbstractThe Ruminative Response Scale (RRS) is commonly used to measure people’s general tendency to ruminate. In this study, we explored whether only few items from the RRS can be used to capture within-person variation in rumination in intensive longitudinal studies. Such a short RRS version would allow, for example, monitoring the development of rumination during clinical interventions. We measured rumination on five occasions, with at least one week in between. We used multilevel analyses to analyze the data at the within- and between-person level. Using only eight RRS items, we successfully modeled a reflective self-regulation and depressive brooding factor, similar to the two subfacets of rumination as distinguished by Treynor et al. (2003). We also established convergent validity of depressive brooding at the within- and between-person level of analysis and convergent validity of reflection at the between-person level. We thus introduced a short form of the RRS that captures within-person variation in depressive brooding and reflection well. The short RRS is readily applicable in studies on within-person variation or change in rumination.
Development and Validation of a Learning Quality Inventory for In-Company Training in VET (VET-LQI)
Authors: Böhn Svenja , Deutscher Viola Katharina 
Published: July 2020

AbstractDespite the importance of dual VET for economic growth and stability, internationally, systems struggle with quality assurance and quality improvement. In recent years, numerous research efforts have been made to identify and describe quality aspects in dual VET, especially with regard to in-company training conditions as perceived by apprentices. This has resulted in an outsized number of test instruments, comprising numerous scales and numerous items. The research presented here aims to assemble and organize all existing survey instruments in the VET context and to develop a comprehensive and validated questionnaire for dual VET that measures workplace characteristics (VET-LQI). For this purpose, 43 test instruments were identified and categorized using a qualitative meta-synthesis, and integrated into a general theoretical framework (Tynjälä 2013). The results of the meta-synthesis reveal diverse content areas as the current foci of VET quality research. The applicability of any existing survey is limited, as the majority of studies either focus on a small range of selected categories and/or do not report the validation results of their scales. Hence, a synthesized item pool was used. Short scales were extracted and tested in seven commercial training occupations in Germany, which covered all identified content areas of VET quality research. On the basis of item and factor analyses, 22 scales (containing 99 items) are identified that, taken together, satisfactorily reflect all common workplace characteristic scales in existent measurement instruments. The resulting instrument provides a broad collection of short scales reflecting the various foci of a longstanding and diverse research tradition, and will allow future researchers to analyze in-company training conditions more comprehensively, given limited opportunities and time resources for testing.
Machine Learning for 3D Particle Tracking in Granular Gases

Published: July 2020

AbstractDilute ensembles of granular matter (so-called granular gases) are nonlinear systems which exhibit fascinating dynamical behavior far from equilibrium, including non-Gaussian distributions of velocities and rotational velocities, clustering, and violation of energy equipartition. In order to understand their dynamic properties, microgravity experiments were performed in suborbital flights and drop tower experiments. Up to now, the experimental images were evaluated mostly manually. Here, we introduce an approach for automatic 3D tracking of positions and orientations of rod-like particles in a dilute ensemble, based on two-view video data analysis. A two-dimensional (2D) localization of particles is performed using a Mask R-CNN neural network trained on a custom data set. The problem of 3D matching of the particles is solved by minimization of the total reprojection error, and finally, particle trajectories are tracked so that ensemble statistics are extracted. Depending on the required accuracy, the software can work fully self-sustainingly or serve as a base for subsequent manual corrections. The approach can be extended to other 3D and 2D particle tracking problems.
Hierarchical assemblies of molecular frameworks—MOF-on-MOF epitaxial heterostructures
Authors: Haldar Ritesh , Wöll Christof 
Published: July 2020

AbstractFunctional, porous metal-organic frameworks (MOFs) have attracted much attention as a very flexible class of crystalline, porous materials. For more advanced applications that exploit photophysical properties, the fabrication of hierarchical assemblies, including the creation of MOF/MOF heterointerfaces, is important. For the manufacturing of superstructures with length scales well beyond that of the MOF pore size, layer-by-layer (lbl) methods are particularly attractive. These allow the isoreticular approach to be extended to superstructures with micrometer length scales, a range that is not accessible using conventional MOF design. The lbl approach further substantially extends the compositional diversity in MOFs. At the same time, the favorable elastic properties of MOFs allow for heteroepitaxial growth, even in the case of lattice misfits as large as 20%. While the MOF-on-MOF approach to designing multicomponent superstructures with synergistic multifunctionality can also be realized with sophisticated solvothermal synthesis schemes, the lbl (or liquid-phase epitaxy) approach carries substantial advantages, in particular when it comes to the integration of such MOF superstructures into optical or electronic devices. While the structure vertical to the substrate can be adjusted using the lbl method, photolithographic methods can be used for lateral structuring. In this review, we will discuss the lbl liquid-phase epitaxy approach to growing surface-anchored MOF thins films (SURMOFs) as well as other relevant one-pot synthesis methods for constructing such hierarchically designed structures and their emerging applications.

AbstractA unique archaeological finding of five individuals buried in an early medieval pit house was discovered in Podersdorf am See (Austria). Three of those individuals were buried in narrow grave pits that had been deepened into the house floor; two of them were lying on the pit floor in a crouched position. Pit houses with six-post construction are known since Roman times and were particularly widespread during the Migration Period. On the basis of radiocarbon analyses of charcoal from the hearth, the use phase of the pit house of Podersdorf am See can be dated to the sixth century AD. The burials took place around the same time in the second half of the seventh century AD, when the house lost its original function. Around that time, regular burials took place in the cemetery in the immediate vicinity of the house. The anthropological examination of the five skeletons showed no significant differences in comparison to the ones that were buried in the cemetery. By means of aDNA analyses, it could be established that at least two of the individuals were closely related to each other.

AbstractRenal transplant is a lifesaving and cost-effective intervention for patients with End Stage Renal Failure. Yet it is often regarded as replacement therapy rather than a cure given the overall failure rate over time. With a shortage of organs, this global issue has been further compounded by increased incidences of obesity, hypertension and diabetes, such that the disease burden and need for transplantation continues to increase. Considering the lifetime of immunosupression in transplant patients, there will also be significant associated co-morbidities By leveraging the advances in innovation in Next Generation Sequencing, the field of transplant can now monitor patients with an optimized surveillance schedule, and change the care paradigm in the post-transplant landscape. Notably, low grade inflammation is an independent risk for mortality across different disease states. In transplantation, sub-clinical inflammation enhances acute and chronic rejection, as well as accelerates pathologies that leads to graft loss. Cell free DNA has been shown to be increased in inflammatory processes as we all as provide an independent predictor of all-cause mortality. This review considers the utility of AlloSure, a donor derived cell free DNA molecular surveillance tool, which has shown new clinical insights on how best to manage renal transplant patients, and how to improve patient outcomes.

Published: July 2020

BackgroundThe direct‐to‐consumer genetic testing (DTC‐GT) industry has exploded in recent years, initiated by market pioneers from the United States and quickly followed by companies from Europe and Asia. In addition to their primary objective of providing ancestry and health information to customers, DTC‐GT services have emerged as a valuable data resource for large‐scale population and genetics studies.MethodsWe assessed DTC‐GT market leaders in the U.S. and China, user participation in research, and academic reports based on this information. We also investigated DTC‐GT end‐user value by tracing key updates of companies provided via health risk reports and evaluating their predictive power. We then assessed the replicability of several genome‐wide association studies (GWAS) based on a Chinese DTC‐GT biobank.ResultsAs recent entrants to the market, Chinese DTC‐GT service providers have published less academic research than their Western counterparts; however, a larger proportion of Chinese users consent to participate in research projects. Dramatic increases in user volume and resultant report updates led to reclassification of some users’ polygenic risk levels, but within a reasonable scale and with increased predictive power. Replicability among GWAS using the Chinese DTC‐GT biobank varied by studied trait, population background, and sample size.ConclusionsWe speculate that the rapid growth in DTC‐GT services, particularly in non‐Caucasian populations, will yield an important and much‐needed resource for biobanking, large‐scale genetic studies, clinical trials, and post‐clinical applications.
Investigation on the wear of spur gears generated by modified cutter
Authors: Zheng Fangyan , Zhang Jun , Yao Ligang , Tan Rulong 
Published: July 2020

AbstractTooth surface wear damage is one of the main causes of gearing system failure. Excessive wear leads to tooth profile loss and an increase in transmission errors, as the worn gear surfaces are no longer conjugate. Thus, the enhancement of gear durability against wear is important for gear application. Recent works show that cutter modification can aid in reducing the tool wear in gear processing, while the wear performance of the gears produced by modified cutters is still unknown. Therefore, this study focuses on the wear performance of the gear generated by modified cutter. Numerical results show that the wear resistance can be enhanced through proper cutter modification.
Surface Water Pollution by Untreated Municipal Wastewater Discharge Due to a Sewer Failure
Authors: Preisner Michał 
Published: July 2020

AbstractThe study is an attempt to assess the pollution impact on the aquatic ecosystem related with an emergency discharge of untreated municipal wastewater from the “Czajka” wastewater treatment plant (WWTP) in Warsaw. The present case study is based on the analysis of available monitoring data for chemical oxygen demand (COD), total nitrogen (TN), ammonia nitrogen (N-NH4), and total phosphorus (TP) in the effluent mixing zone (MZ), the stretch of the river and before the discharge point. Data analysis was supported by a basic statistical analysis based on Pearson’s correlation coefficient. The results proved the importance of efficient and reliable nutrient removal technologies used in modern WWTPs. A statistically significant correlation was achieved between the COD (r = 0.567) and TP (r = 0.714) discharged loads and their concentration in the MZ. However, no significant correlation has been identified with TN and N-NH4. Furthermore, the dissolved oxygen (DO) deficits in the MZ were observed within 7 days of the discharge period resulting in an average DO concentration decrease from 8.4 to 7.1 mgO2/L. The river stretch has not been affected by DO deficits while the average observed DO concentration 30 km behind the discharge point was 9.1 mgO2/L. The analysis results present the pollutants assimilation capacity of a river ecosystem and its real reaction to sudden excessive nutrient loads discharge.

Published: July 2020

AbstractCarbides/carbon composites are emerging as a new kind of binary dielectric systems with good microwave absorption performance. Herein, we obtain a series of tungsten carbide/carbon composites through a simple solvent-free strategy, where the solid mixture of dicyandiamide (DCA) and ammonium metatungstate (AM) is employed as the precursor. Ultrafine cubic WC1−x nanoparticles (3–4 nm) are in situ generated and uniformly dispersed on carbon nanosheets. This configuration overcomes some disadvantages of conventional carbides/carbon composites and is greatly helpful for electromagnetic dissipation. It is found that the weight ratio of DCA to AM can regulate chemical composition of these composites, while less impact on the average size of WC1−x nanoparticles. With the increase in carbon nanosheets, the relative complex permittivity and dielectric loss ability are constantly enhanced through conductive loss and polarization relaxation. The different dielectric properties endow these composites with distinguishable attenuation ability and impedance matching. When DCA/AM weight ratio is 6.0, the optimized composite can produce good microwave absorption performance, whose strongest reflection loss intensity reaches up to − 55.6 dB at 17.5 GHz and qualified absorption bandwidth covers 3.6–18.0 GHz by manipulating the thickness from 1.0 to 5.0 mm. Such a performance is superior to many conventional carbides/carbon composites.

Published: July 2020

AbstractSuper-hydrophobic surfaces are quite common in nature, inspiring people to continually explore its water-repellence property and applications to our lives. It has been generally agreed that the property of super-hydrophobicity is mainly contributed by the microscale or nanoscale (or even smaller) architecture on the surface. Besides, there is an energy barrier between the Cassie-Baxter wetting state and the Wenzel wetting state. An optimized square post micro structure with truncated square pyramid geometry is introduced in this work to increase the energy barrier, enhancing the robustness of super-hydrophobicity. Theoretical analysis is conducted based on the wetting transition energy curves. Numerical simulation based on a phase-field lattice Boltzmann method is carried out to verify the theoretical analysis. The numerical simulation agrees well with the theoretical analysis, showing the positive significance of the proposed micro structure. Furthermore, another novel micro structure of rough surface is presented, which combines the advantages of truncated pyramid geometry and noncommunicating roughness elements. Theoretical analysis shows that the novel micro structure of rough surface can effectively hinder the Cassie-Baxter state to Wenzel state transition, furtherly enhancing the robustness of the surface hydrophobicity.

Published: July 2020

AbstractMedical collapse became a major concern under coronavirus disease 2019 (COVID-19) outbreak; prevention of medical accidents is essential during disinfection either. The objective of this review is to enhance the awareness regarding the safety aspects towards infection prevention practices and to offer solutions for safe patient care practices including side effects of disinfectants and precaution in specific medical facilities especially in hemodialysis rooms, intensive care unit, hyperbaric oxygen therapy (HBO) chambers, or patient transport vehicle. Literature was researched that was obtained from studies of human coronavirus infections, including the severe acute respiratory syndrome (SARS) and the Middle East respiratory syndrome (MERS), and created a summary of the characteristics of these disinfectants. This review is not intended to replace infection prevention policies and procedures established by hospitals, and manufacturers, but to provide some update confidence in the safety measures that each medical facility already uses and to offer additional input that should optimally reduce the risk of infection.
A Modified Normalized Weighting Factor method for improving the efficiency of the blended high-resolution advection schemes in the context of multiphase flows
Authors: Mariño-Salguero Jessica , Schäfer Michael 
Published: July 2020

AbstractThis work deals with a new methodology for the implementation of high-resolution (HR) schemes employed to advect the volume fraction in the volume of fluid (VOF) method, in which the numerical stability and convergence depend heavily on the numerical advection scheme and implementation method. The proposed method is based on the normalized weighting factor (NWF) method, which linearizes the normalized interpolation profile and rewrites the face value directly using the donor, acceptor, and upwind nodes. However, unlike the NWF, which is fully implicit and results in pentadiagonal linear systems, the new modified normalized weighting factor (MNWF) method only forms the implicit terms with the contribution of the donor and acceptor nodes, while the contribution of the upwind node explicitly forms part of the source term. Therefore, the method results in a tridiagonal linear system. The comparison of the new method with the deferred correction (DC), downwind weighting factor (DWF), and the RNWF methods shows that the MNWF requires about 5%–25% fewer iterations than DC and RNWF, and around 10%–85% less than DWF. Thus, a similar order of accuracy of the results can be o btained with less computational time.
