'A time of constant innovation!' - The impact of the COVID-19 pandemic on the teaching of food practical Home Economics in Ireland, and learning for future best practice: an explanatory mixed methods study
Authors: Winters Grace , Maguire Helen 
Published: October 2022

Background: The ongoing global pandemic of SARS-CoV-2 (COVID-19) (WHO, 2020) utterly disrupted traditional modes of education nationally and internationally. Mastering online teaching imposed by the COVID-19 pandemic was challenging for many teachers. The purpose of the study was to illuminate the challenges experienced by food practical Home Economics teachers, investigating their ability to innovate, adapt and proceed with food practical classes during the COVID-19 pandemic. This study also aimed to discover best practical methodologies for online and face-to-face food practical classes while looking forward with reimagined approaches to teaching and learning for a post-pandemic world and documented teachers experiences, agency, adaptations and innovations. Methods: Both qualitative and quantitative research methods were employed to meet study objectives. Data was gathered in the Republic of Ireland via 132 questionnaires with Home Economics teachers and semi-structured interviews with six Home Economics teachers. Results: Results revealed that COVID-19 imposed serious challenges on teachers who nonetheless adapted well to the changing environment. They employed innovation and determination to proceed with practical classes in very challenging working environments, resulting in many positive educational advances. Teachers up-skilled, reflected and collaborated to proceed safely with practical’s and deduced best practice methodologies which in a number of cases arose from trial and error. Findings were employed to produce frameworks for best practice when conducting food practical Home Economics classes (both online and face-to-face). These frameworks have national and international relevance in considering new models of teaching in which authentic teaching can occur and provide alternative pedagogies and technologies to support the food practical. Conclusion: This study recommends more technological training for Home Economics teachers, specifically regarding practical classes, as well as support for physical working environments, collaboration and innovation. This research is focused on how teaching can be reimagined, strengthened and valued to inform future teaching and learning models.
The Power of Adaptivity for Stochastic Submodular Cover
Authors: Ghuge Rohan , Gupta Anupam , Nagarajan Viswanath 
Published: October 2022

Adaptivity in Stochastic Submodular Cover Solutions to stochastic optimization problems are typically sequential decision processes that make decisions one by one, waiting for (and using) the feedback from each decision. Whereas such “adaptive” solutions achieve the best objective, they can be very time-consuming because of the need to wait for feedback after each decision. A natural question is are there solutions that only adapt (i.e., wait for feedback) a few times whereas still being competitive with the fully adaptive optimal solution? In “The Power of Adaptivity for Stochastic Submodular Cover,” Ghuge, Gupta, and Nagarajan resolve this question in the context of stochastic submodular cover, which is a fundamental stochastic covering problem. They provide algorithms that achieve a smooth trade-off between the number of adaptive “rounds” and the solution quality. The authors also demonstrate via experiments on real-world and synthetic data sets that, even for problems with more than 1,000 decisions, about six rounds of adaptivity suffice to obtain solutions nearly as good as fully adaptive solutions.

Published: October 2022

Background
Brazil occupies the fifth position in the ranking of the highest mortality rates due to RTI in the world. With the objective of promoting traffic safety and consequently reducing deaths, Brazil created the Life in Traffic Project (LTP). The main goal of LTP is reducing 50% of RTI deaths, by promoting interventions to tackle risk factors, such as driving under the influence of alcohol and excessive and/or inappropriate speed. Thus, the aim of this study was to estimate the magnitude of risky and protective factors for RTI in capitals participating in the LTP in Brazil. We estimated these factors according to sociodemographic (age group, sex, education, race and, type of road user).

Methods
A total of 5,922 car drivers and motorcyclists from 14 Brazilian capitals participating in the LTP were interviewed. Data collection was carried out in sobriety checkpoints at night and consisted of the administration of an interview and a breathalyzer test. Risky and protective behaviors associated with RTI were investigated. Covariates of the study were: age, sex, education, race and, type of road user. Poisson multiple regression analysis was used to assess the relationship between variables of interest.

Results
The prevalence of individuals with positive blood alcohol concentration (BAC) was 6.3% and who reported driving after drinking alcohol in the last 30 days was 9.1%. The others risky behaviors reported were: driving at excessive speed on roads of 50 km/h, using a cell phone for calls while driving, using a cell phone to send or read calls while driving, running a red light. Use of seatbelts and helmets showed prevalence above 96,0% Use of seatbelts showed prevalence of 98.6% among car drivers, and helmet use was described by 96.6% of motorcycle drivers. Most risky behaviors were more prevalent in younger age groups (except BAC measurement higher in older participants), in males (except for cell phone use), in participants with higher education level and without a driver’s license.

Conclusion
Excessive speed and driving under the influence of alcohol, defined as priorities within the LTP, need more consistent interventions, as they still have considerable prevalence in the cities investigated. The factors described such as cell phone usage and passing red traffic lights should also need to be prioritized as a focus on promoting traffic safety.
Um exemplo da influência da litologia na estabilidade de taludes
Authors: Oliveira Ricardo 
Published: October 2022

A margem direita do rio Tejo, nas proximidades de Santarém, a 70 Km para NE de Lisboa é uma encosta com cerca de 2 Km de comprimento e 80 m de altura.
As formações geológicas são constituídas por intercalações de complexos arenosos e argilo-siltosos sub-horizontais com carácter de estuário.
As inclinações da encosta variam entre 30° e 40° na maior parte da sua extensão. Como consequência, ocorrem todos os anos pequenos escorregamentos e quedas devidos à perda de coesão das formações. Um importante escorregamento ocorreu recentemente numa das extremidades da encosta, envolvendo cerca de 200.000 m3 de terras. Nesta zona a inclinação da encosta era apenas de 20º, pelo que não era de esperar que ocorresse qualquer escorregamento.
O estudo realizado levou à conclusão que o acidente foi devido à presença de um nível de argilas plásticas orgãnicas, intercalado num dos complexos argilo-siltosos, localizado a meia altura da encosta, onde se iniciou um lento processo de fluência que conduziu à rotura. Este nível de argila orgânica apenas ocorre na zona onde se deu o escorregamento.
Does plantar skin abrasion affect cutaneous mechanosensation?
Authors: Wynands Bert , Zippenfennig Claudio , Holowka Nicholas B. , Lieberman Daniel E. , Milani Thomas L. 
Published: October 2022

AbstractIn humans, plantar cutaneous mechanoreceptors provide critical input signals for postural control during walking and running. Because these receptors are located within the dermis, the mechanical properties of the overlying epidermis likely affect the transmission of external stimuli. Epidermal layers are highly adaptable and can form hard and thick protective calluses, but their effects on plantar sensitivity are currently disputed. Some research has shown no effect of epidermal properties on sensitivity to vibrations, whereas other research suggests that vibration and touch sensitivity diminishes with a thicker and harder epidermis. To address this conflict, we conducted an intervention study where 26 participants underwent a callus abrasion while an age‐matched control group (n = 16) received no treatment. Skin hardness and thickness as well as vibration perception thresholds and touch sensitivity thresholds were collected before and after the intervention. The Callus abrasion significantly decreased skin properties. The intervention group exhibited no change in vibration sensitivity but had significantly better touch sensitivity. We argue that touch sensitivity was impeded by calluses because hard skin disperses the monofilament's standardized pressure used to stimulate the mechanoreceptors over a larger area, decreasing indentation depth and therefore stimulus intensity. However, vibration sensitivity was unaffected because the vibrating probe was adjusted to reach specific indentation depths, and thus stimulus intensity was not affected by skin properties. Since objects underfoot necessarily indent plantar skin during weight‐bearing, calluses should not affect mechanosensation during standing, walking, or running.
Association between Economic Growth, Mortality, and Healthcare Spending in 31 High-Income Countries

Published: October 2022

Abstract
This study aims to investigate the association between gross domestic product (GDP), mortality rate (MR) and current healthcare expenditure (CHE) in 31 high-income countries. We used panel data from 2000 to 2017 collected from WHO and OECD databases. The association between CHE, GDP and MR was investigated through a random-effects model. To control for reverse causality, we adopted a test of Granger causality. The model shows that the MR has a statistically significant and negative effect on CHE and that an increase in GDP is associated with an increase of CHE (p < 0.001). The Granger causality analysis shows that all the variables exhibit a bidirectional causality. We found a two-way relationship between GDP and CHE. Our analysis highlights the economic multiplier effect of CHE. In the debate on the optimal allocation of resources, this evidence should be taken into due consideration.

Published: October 2022

Abstract
Macrophages in the tumor microenvironment (TME) can serve as potential targets for therapeutic intervention. The aim of this study was to investigate the molecular mechanism by which M2 macrophage-derived exosomes (M2-Ex) affect lung cancer progression through miRNA transport. The THP-1 cells were differentiated into M0 and M2 macrophages. M2-Ex were isolated and identified by transmission electron microscopy (TEM) and nanoparticle tracking analysis (NTA). Cancer tissues and adjacent tissues of non-small-cell lung cancer (NSCLC) patients were collected. H1299 and A549 cells were co-cultured with M2-Ex. Subcutaneous xenograft mouse model was established. miR-3917 is highly expressed in lung cancer tissues and M2-Ex. Interference of miR-3917 in M2-Ex inhibits H1299 cell proliferation, migration and invasion, while overexpression of miR-3917 had the opposite effect in A549 cells. M2-Ex promote tumor growth by delivering miR-3917 in vivo. miR-3917 could target G protein-coupled receptor kinase 6 (GRK6), and interference of miR-3917 in M2-Ex inhibits H1299 cells proliferation, migration and invasion by up-regulating GRK6 level, while overexpression of miR-3917 had the opposite effect in A549 cells. M2-Ex can transfer miR-3917 into lung cancer cells and promote lung cancer progression, providing theoretical basis for the diagnosis and effective treatment of lung cancer.
Membrane binding and pore forming insertion of PEX5 into horizontal lipid bilayer

Published: October 2022

Abstract
The assembly of the peroxisomal translocon involves the transition of a soluble form of the peroxisomal targeting receptor PEX5 into a membrane-bound form, which becomes an integral membrane component of the import pore for peroxisomal matrix proteins. How this transition occurs is still a mystery. We addressed this question using a artificial horizontal bilayer in combination with fluorescence time-correlated single photon counting (TCSPC) and electrophysiological channel recording. Purified human isoform PEX5L and truncated PEX5L(1–335) lacking the cargo binding domain were selectively labeled with thiol-reactive Atto-dyes. Diffusion coefficients of labeled protein in solution show that PEX5L is monomeric with a rather compact spherical conformation, while the truncated protein appeared in a more extended conformation. Labeled PEX5L and the truncated PEX5L(1–335) bind stably to horizontal bilayer thereby accumulating around 100-fold. The diffusion coefficients of the membrane-bound PEX5L forms are 3–4 times lower than in solution, indicating the formation of larger complexes. Electrophysiological single channel recording shows that membrane-bound labeled and non-labeled PEX5L, but not the truncated PEX5L(1–335), can form ion conducting membrane channels. The data suggest that PEX5L is the pore-forming component of the oligomeric peroxisomal translocon and that spontaneous PEX5L membrane surface binding might be an important step in its assembly.

Published: October 2022

AbstractThis purpose of this research work primarily focuses on assessing the contact characteristics of a novel 3D printed flexible poly lactic acid (PLA) fingertip exposed to a normal load ranging from 1–750 N. The 3D printed fingertip is pressed against three different target surfaces having concave, convex and flat profiles to facilitate a rational comparison. The growth of contact area is recorded for a wide range of applied normal force against the fingertip on logging sheets and the same is converted in vector format for facilitating digital measurements. From close examination of the results, it may be noted that the rate of growth of contact area follows the parametric relationshipa=cNγ. A weighted least squares fit algorithm is used to formulate the parametric relationship based on experimental data. Further, the contact characteristics of the 3D printed fingertip follows the same pattern of soft neoprene fingertip, and it is well in line with the expected results. Hence, it is evident that 3D printed fingertips could be utilized for handling fragile to hard objects and capable of handling multi-profiled objects in dexterous robotic manipulation. Moreover, complex profiled fingertips can easily be manufactured by 3D printing, and it can be considered as a better alternative for conventionally manufactured anthropomorphic robotic grippers. Practical implications of this research will be highly useful for development of soft-fingered robotic grippers for dexterous robotic manipulations.
Coordinated target tracking in sensor networks by maximizing mutual information
Authors: Wang Yintao , Xie Fuchao 
Published: October 2022

AbstractThis paper addresses the problem of coordinated target tracking in sensor networks. For a typical target tracking scene with nonlinear bearing-only measurements, we first investigate the mutual information between multiple sensors and the target state. To improve the performance of target tracking, we analyzed the relative positions between sensor agents and the target to be tracked and derived the optimal positions for sensors in the network by mutual information maximization. Simulation results are presented and discussed to demonstrate that the performance of estimated target states could be improved by the proposed method.

Comparative analysis of written corrective feedback strategies: a linear growth modeling approach
Authors: Shin Hye Won 
Published: October 2022

Abstract
The purpose of this study was to examine the development of English article accuracy in second language writing following direct or indirect corrective feedback (CF). Participants were 56 middle-school-aged learners of English nested within four classrooms who were studying for the writing portion of the Secondary School Admission Test. In this longitudinal analysis, each student completed four essays, with a weekly gap between each assignment. On the measures of writing accuracy, adolescent students in the direct CF group demonstrated increasing trajectories of accuracy with English article usage compared to the indirect CF group. Additionally, there was a significant difference in improvement by proficiency level: for lower proficiency learners, but not higher proficiency learners, both indirect and direct corrective feedback resulted in improvement in English article accuracy. The findings suggest that CF treatments designed to enhance a learner’s accuracy can be influenced by the learner’s existing proficiency, at least among adolescents.
A Harmonized Net Wealth Tax in the European Union
Authors: Krenek Alexander , Schratzenstaller Margit 
Published: October 2022

AbstractWhile taxes on wealth for a long time played only a marginal role in the public finance and taxation literature, the increase of wealth inequality and concentration in many EU countries has spurred new interest in wealth taxation. At the same time, recurrent net wealth taxes have almost completely disappeared in Europe, inter alia due to fears of asset and taxpayer migration. The paper provides estimates of the revenue that could be raised from an EU-wide net wealth tax enabling the containment of migration responses, using data from the Household, Finance and Consumption Survey (HFCS). To account for differential non-response, we augment the HFCS with data from the Forbes rich list as well as national rich lists and replace the top tail of the wealth distribution according to the HFCS by an estimated Pareto distributed top tail. To account for under-reporting we scale aggregate financial assets in the HFCS to match their counterparts outlined in the National Accounts. We estimate that a moderately progressive net wealth tax levied at a rate of 1% on net wealth between € 1 and € 5 million, and 1.5% on wealth above € 5 million, could raise between € 165 and € 177 billion after accounting for avoidance and evasion responses. Such an EU harmonized net wealth tax would affect only a small fraction of households, ranging between 0.41% in Latvia and 8.65% in Belgium.

Published: October 2022

Abstract
We numerically investigate and statistically analyze the impact of medium parameters (modulation depth P, modulation factor ω, and gain/loss strength W
0) and beam parameters (truncation coefficient a and distribution factor χ
0) on the propagation characteristics of a cosh-Airy beam in the Gaussian parity-time (PT)-symmetric potential. It is demonstrated that the main lobe of a cosh-Airy beam is captured as a soliton, which varies periodically during propagation. The residual beam self-accelerates along a parabolic trajectory due to the self-healing property. With increment in P, the period of a trapped soliton decreases almost monotonically, while the peak power of a trapped soliton increases monotonically. With the increase in ω or decrease in the absolute value of W
0, the period and peak power of a trapped soliton decrease rapidly and then almost remain unchanged. Moreover, it is indicated that the period of a trapped soliton remains basically unchanged no matter a and χ
0 increase or decrease. The peak power of a trapped soliton increases with increment of a, but the peak power of a trapped soliton stays relatively constant irrespective of variation in χ
0.
