Authors: Lassance Laura , Filgueiras Lucia Vilela Leite , Dessus Philippe , Guntz Thomas , Crowley James
Published: September 2022

The growing availability of online multimedia instructions, such as Massive Open Online Courses (MOOCs) mark a revolutionary new phase in the use of technology for education. Considering the high student attrition in MOOCs, it is crucial to study how students engage and disengage during their learning experience in relation to the video lecture design. The present study conducted a pilot user experiment (n = 24) to evaluate in a multimodal way which video lecture design is more effective for learning. Two video lecture designs were scrutinized: voice over slides, and slides overlaid by picture-in-picture instructor video. The experimental setup included different tracking technologies and sensorial modalities to gather synchronized data from the learning experience: eye-tracker, Kinect, frontal camera, and screen recording. Among the measures, eye-gaze observational data, facial expressions, and self-reported perceptions were analyzed and compared against the learning assessment results. Based on these results, engagement is discussed regarding the different video lecture designs by connecting the observational and self-reported data to the short-term learning outcomes.
Preregistration: Definition, advantages, disadvantages, and how it can help against questionable research practices
Authors: Krypotos Angelos-Miltiadis , Mertens Gaëtan , Klugkist Irene , Engelhard Iris
Published: September 2022

{PREPRINT} Questionable Research Practices (QRPs), such as p-hacking (i.e., the inappropriate manipulation of data analysis to find statistical significance) and post-hoc hypothesizing, are threats to replicability of research findings. One key solution to the problem of QRPs is pre- registration. This refers to time-stamped documentation that describes the methodology and statistical analyses of a study before the data are collected or inspected. As such, readers of the study’s report can evaluate whether the described research is in line with the planned methods and analyses or there are deviations from these (e.g., analyses performed so that the research hypotheses is confirmed). Here, we aim to describe what preregistration entails and why it is useful for psychology research. In this vein, we present the key elements of a sufficient preregistration file, its advantages, as well as its disadvantages, and why preregistration is a key, yet partially insufficient, solution against QRPs. By the end of this chapter, we hope that readers are convinced that there is little reason not to preregister their research.

Background: Previous research suggests attachment is a vulnerability factor for self-harm thoughts and behaviours in adults. Yet, few studies have investigated this relationship during adolescence, even though adolescence is a critical period for changes in attachment relationships, and self-harm onset. Whether and how attachment relates to self-harm thoughts and behaviours as measured in daily life is also unknown. Aims: To investigate whether and how paternal, maternal, and peer attachment are associated with lifetime and current adolescent self-harm thoughts and behaviours. Additionally, to examine how different attachment bonds interact in relation to lifetime and current adolescent self-harm thoughts and behaviours.Method: Pre-existing data from N=1913 adolescents of the SIGMA study were used. Attachment and lifetime history of self-harm thoughts and behaviours were measured via retrospective questionnaires. Current self-harm thoughts and behaviours were assessed ten times per day for six days using the Experience Sampling Method (ESM). Results: Paternal and maternal attachment were associated with lifetime self-harm thoughts and behaviours and current self-harm thoughts. No significant associations were found between peer attachment and self-harm outcomes. Limitations: Some analyses were underpowered. Conclusion: Our results highlight the importance of parent-child attachment relationships, which may be intervention targets for prevention and treatment of adolescent self-harm.

A pertença dos fiéis pendulares à paróquia eletiva. Novos critérios de adscrição a uma nova paróquia (Parte I)
Authors: França Marcio Fernando
Published: September 2022

Dos vários efeitos oriundos da urbanização, especial interesse ocorre pelo movimento pendular ou pendularidade, fenômeno relacionado à crescente mobilidade dos indivíduos que, confrontado ao problema pastoral atual dos fiéis que optam por frequentar uma paróquia distinta daquela que lhe foi designada pelo Direito em virtude do seu domicílio, garante uma dupla novidade no âmbito eclesial: o fiel pendular e a paróquia eletiva. Em razão dos problemas surgentes e das limitações dos critérios territorial e pessoal em responder este novo fenômeno pastoral, arbitra-se uma propositio de mudança: por uma razão pessoal objetiva, o fiel poderá ser adscrito à paróquia por ele eleita. Para tanto, é fundamental a promulgação de uma lei particular para regulamentar tal matéria em âmbito diocesano, bem como a implementação de um itinerário para perscrutar esta razão pessoal e a intenção última resultante da escolha do fiel, o que permitirá uma correta tomada de decisão por parte da autoridade competente.

Percut Village is a popular tourist destination in Percut Sei Tuan District, drawing visitors from all over the country, particularly on Saturdays and Sundays. There is a culinary tour in this town that serves several varieties of fish meals that guests can choose according to their preferences. Visitors can enjoy the relaxing sea views until they approach the Malaysian border on their way to the gastronomic destination. Visitors will be transported to the gastronomic destination via free fishing boats provided by the café owner. There is also a Fish Auction Place (TPI) in this village, which attracts inhabitants who want to buy fresh fish at a low price compared to other localities. The other issue is that local folks' ability to communicate in order to entice tourists to return is still restricted. Residents' willingness to take advantage of the possibility to make things for sale is still low. Based on the dedication shown, the communication training provided to partners has proven to be very effective in promoting the various types of tourism available in Percut village, as well as the socializing provided to keep the environment clean. However, the Covid 19 epidemic, which is still rampant, has severely harmed partners' culinary businesses and fish auctions.Percut Village has tourism potential, particularly in the fields of marine tourism, beach tourism, and culinary tourism; socialization about tourism communication is very useful for opening culinary tourism visits in Percut Village; residents' understanding of environmental maintenance procedures and healthy homes is still low; and The development of Covid 19 and the imposition of Community Activity Restrictions (PPKM) had a significant impact on Percut Village's tourism appeal.

Published: September 2022

Banyuanyar Lor Village is one of the villages in the Probolinggo Regency, East Java. Most of the residents of this village make a living as onion farmers. At least 85 percent of the residents are shallots farmers. shallots farmers play an important role in maintaining the sustainability of Probolinggo Regency as a producer of shallots that have economic advantage as in the community system, processing, and processing of shallots. Shallots are of the strategic commodities that are produced periodically and are superior in this village. Unfortunately, these agricultural products have limited added value. Shallots, if not sold directly, are only processed as snacks, additional spices, and others whose marketing is not yet wide enough. Combining village advantages and agricultural potential and empowering women, socialization activities that open opportunities for collaboration in the field of community service are carried out. This socialization activity was inserted with processed red onion products in the form of cookies created by the creativity of students participating in KKN. This socialization activity is a collaboration of major post-pandemic themes such as "Recover Faster, Rise Stronger", creative economy, economic independence and entrepreneurship in 3 collaborative activities that are sharing experiences and invitations to rise up after the pandemic.
Caveat Emptor: The Perils of Shopping for Medical Products in the Ancient Marketplace
Authors: Becker Hilary
Published: September 2022

Authors such as Scribonius Largus, Dioscorides, Pliny the Elder, and Galen were concerned with the materials used to treat illness and warned consumers against rampant fraud practiced in the ancient drug industry. Reading these texts alongside the archaeological evidence for ancient medicine, such as stamps for collyria (eye salves) and the containers and labels used to package the products, makes it possible to understand a commercial market fraught with possibilities for fraud and adulteration. It is worthwhile to explore how Roman consumers and even doctors could navigate such a marketplace so that they could locate bona fide products.

Authors: Jafari R. , Kiilakoski J. , Honkanen M. , Vippola M. , Koivuluoto H.
Published: September 2022

High-pressure cold spraying has shown significant potential in manufacturing metallic composite coatings for a wide range of industrial applications, including wear and corrosion protection. Quasi-crystalline materials, in turn, are promising candidates due to their unique microstructural features. Combining these concepts, metallic composite coatings were generated using high-pressure cold spraying to produce functional and protective coatings. Several spray trials were done to detect the effect of compositions and size of quasi-crystalline feedstock materials mixed with metal powders, Al6061, and stainless steel 316L, on coating microstructure, integrity, and surface properties. A scanning electron microscope was used to examine the microstructure of the feedstock materials and composite coatings. A 3D surface optical profilometer was also used to investigate surface texture. The wettability of the coating surfaces was measured by static water contact angles using a droplet shape analyzer. Cold-sprayed quasi-crystalline composite coatings showed denser and well-integrated deposits with a random distribution of phases across the composite surface, indicating promising structural reliability and hydrophobic behavior.

Published: September 2022

Viruses and microbial pathogens can survive for hours on fabrics. This paper reports that copper-doping of natural and synthetic fabrics inactivates, within minutes, a human COVID surrogate pathogen. The fabric is embedded with copper particles by twin-wire arc thermal spray. The long-lasting fabric surface simultaneously provides good breathability, it is scalable and cost-effective. Virucidal activity is not affected by repeated washing of the fabric. Importantly, copper-embedded material will provide effective protection against all classes of pathogens, regardless of their mutation rates and infection strategies. It also can provide protection against all classes of pathogens, regardless of their mutation rates in industrial and residential filters.
Design of High Entropy Alloys for Thermal Spray Processes Using Machine Learning
Authors: Kamnis S. , Sfikas A. K. , Gonzalez S.
Published: September 2022

Throughout the years, parametric and computational approaches have been used extensively for the design of High Entropy Alloys (HEA) and Multicomponent Element Alloys (MEA). Machine learning (ML) approaches have been extensively used to circumvent the fundamental issues that challenge the proposed theories, models, and methods for conventional alloys. Highly accurate ML models rely heavily on the quality of data and the design features that are used as inputs to the model. The applicability of these methods for phase formation predictions is questionable when it comes to the design of thermally sprayed HEA coatings using gas or water atomized powders as feedstock material. Phase formation from liquid state depends on the cooling rate during solidification which is several orders of magnitude higher when compared to arc melted as-cast HEAs. In addition, during plasma spray the powder melts in the flame and re-solidifies under different cooling rates during deposition. To our knowledge, almost all ML algorithms are based on available datasets constructed from relatively low cooling rate processes such as arc melting and suction casting. A new approach is needed to broaden the applicability of ML algorithms to rapid solidification manufacturing processes similar to gas and water atomization by making use of existing data and theoretical models. In this study the authors introduce a cooling rate dependent design feature that can lead to accurate predictions of the HEA powder phase formation and the subsequent phases found in the spray coated materials. The model is validated by comparing the predictions with existing coating related data in the literature.
A Machine Learning Based Approach for Cold Spray Deposition Porosity Prediction from Processing Parameters
Authors: Roy S. , Ravi K.
Published: September 2022

Cold spray is a high-speed solid state deposition technique which allows for fabricating coatings and free standings structures by careful tuning of process parameters. However due to the complex dependencies of the process parameters a machine learning approach is utilized in this work to predict the coating properties. A machine learning (ML)-based data driven platform for determining the deposition porosity for cold sprayed deposition with the goal of reducing product cost and time has been developed. In this work, five ML models - Linear Regression, Decision Tree Regression and Random Forest Regression, XGBRegressor and LGBMRegressor are compared for the prediction of coating porosity from spray and material parameters namely Heat Capacity Ratio of carrier gas, Processing Gas Temperature, Processing gas pressure, Standoff Distance, Average Powder Diameter, Powder Material Density, and the Substrate density. A total number of 227 data sets were extracted from an extensive literature survey on cold spray deposition of metal/alloy powders which were used to train the ML models. The data analysis showed strong and weak correlations of several processing parameters with the coating porosity. The processing gas temperature and pressure have a negative and average powder diameter has a positive correlation with the deposition porosity. The coating porosities of 10 unknown sets (which were not included in the training or the validation data sets) of processing parameters predicted by the trained algorithms were compared with each other. Decision Tree regression algorithm showed the most appropriate predictions with R2 Fit of 0.75 and MAE of 2.93, while the Linear Regression model did the worst predictions with R2 Fit of 0.27 and MAE of 5.064.

Authors: Modarresi S. , Leonard G. , Carlesso L.C.
Published: September 2022

We investigated the association of sleep quality with the Central Sensitization Inventory (CSI), pressure pain thresholds (PPT), temporal summation, and conditioned pain modulation (CPM) in 251 people with knee osteoarthritis, adjusted for sex, age, body mass index (BMI), anxiety-depressive symptoms, pain catastrophizing, fatigue, comorbidities, and radiographic severity. Overall, sleep quality was associated with changes in the CSI and PPT. However, when stratified by sex, only women had changes in sleep associated with the CSI, PPT, and CPM. Longitudinal studies should confirm these findings.

Published: September 2022

Objective: This project aimed to train nurses on an oncology unit in hypnotic communication to reduce treatment-related pain and anxiety in their patients. A pilot study was conducted to assess changes in hypnotic communication behaviors associated with the training.

Methods: Nurses were recruited and their interactions during a simulated patient admission for treatment (before and after training) were recorded. Hypnotic communication skills were assessed by independent reviewers using a training checklist listing different hypnotic communication techniques and a validated assessment scale (Sainte-Justine Hypnotic Communication Assessment Scale, SJ-HCAS).

Results: Seven nurses were evaluated. Wilcoxon paired-sample tests (pre–post) reported significant improvement with large effect sizes in the total score of the training grid (P = 0.034, r = 0.832) and significant improvement with large effect sizes in the relational (P = 0.018, r = 0.930) and total (P = 0.021, r = 0.903) scores of the SJ-HCAS.

Conclusion: This pilot study shows promising results regarding the effectiveness of hypnotic communication training for nurses. These acquired skills could translate into improved treatment experience with patients and could be transferred to other professionals and settings in the health care system.
A Generalized Notion of Consistency with Applications to Formal Argumentation
Authors: Baroni Pietro , Cerutti Federico , Giacomin Massimiliano
Published: September 2022

We propose a generic notion of consistency in an abstract labelling setting, based on two relations: one of intolerance between the labelled elements and one of incompatibility between the labels assigned to them, thus allowing a spectrum of consistency requirements depending on the actual choice of these relations. As a first application to formal argumentation, we show that traditional Dung’s semantics can be put in correspondence with different consistency requirements in this context. We consider then the issue of consistency preservation when a labelling is obtained as a synthesis of a set of labellings, as is the case for the traditional notion of argument justification. In this context we provide a general characterization of consistency-preserving synthesis functions and analyze the case of argument justification in this respect.
On the Impact of Data Selection when Applying Machine Learning in Abstract Argumentation
Authors: Kuhlmann Isabelle , Wujek Thorsten , Thimm Matthias
Published: September 2022

We examine the impact of both training and test data selection in machine learning applications for abstract argumentation, in terms of prediction accuracy and generalizability. For that, we first review previous studies from a data-centric perspective and conduct some experiments to back up our analysis. We further present a novel algorithm to generate particularly challenging argumentation frameworks wrt. the task of deciding skeptical acceptability under preferred semantics. Moreover, we investigate graph-theoretical aspects of the existing datasets and perform some experiments which show that some simple properties (such as in-degree and out-degree of an argument) are already quite strong indicators of whether or not an argument is skeptically accepted under preferred semantics.

Published: September 2022

In the term scaffolding itself can be interpreted that the word "scaffold" which is often used in building work, which is one of the temporary structures that help a job that can complete the work that is experiencing difficulties, so it cannot be done in the job. In this case scaffolding can help the achievement that cannot be solved individually. Then we can develop the term so that it can be said that one of the formation provided by the teacher or peer group, even his parents in supporting learning, in this case has a high ability factor that is owned by someone. In scaffolding the teacher is able to complete tasks or concepts in terms of learning that can be managed individually. In this case educators only provide skills in innovation or new knowledge from those who have been given assignments that are outside the area within the limits of students' learning abilities.

               In scaffolding mathematics learning in this case hopefully can make the formation of traits in learning better, so that in the process of building students can carry out their own, even have their own knowledge in learning. In this matter discussed are the notions of scaffolding, cognitive learning theory, the strengths and weaknesses of scaffolding, the learning method, the steps of the learning method and even the application of problem solving to mathematics. So that there is an alternative strategy implementation in the application of scaffolding which includes stages such as exploitation, reviewing, restructuring, and developing conceptual thinking. Therefore, this journal will discuss it all. Hopefully it can make the development of changes that support the process of learning mathematics at this time.

The purpose of this study was to determine student thinking styles in solving mathematical problems in integer count operations material through the Realistic Mathematical Approach (PMRI) assisted by colored paper media. This research method is a qualitative method. Data collection instruments using test, observation and documentation. Learning at the primary school level tends to be textbook oriented and conventional so that it requires student learning innovation that can facilitate mathematics learning. The realistic mathematics approach (PMRI) is one of the innovations that connect student real world with learning mathematics in solving mathematical problems. In the world of education, the characteristics of students' thinking styles in learning are not taken into account, which should be considered in learning. Peaget's development theory states that elementary school students fall into the category of concrete operations stages so that researchers use colored paper media to assist students in understanding the operations of addition and subtraction of integers.
