Investigating Factors Influencing Students’ Behavioral Intentions Towards Mobile Learning Devices in Higher Educational Institutions
Authors: Ditlhokwa Gopolang
Published: October 2022

This study adopted two key variables of the technology acceptance model, thus perceived usefulness, self-efficacy, and (gratification) variable of uses and gratification theory to understand how the three variables predict students’ behavioral intentions towards the use of mobile learning devices (MLDs). The sample was drawn from 447 selected participants from four private universities in Gaborone, Botswana. The researcher analyzed the data and presented the findings by testing the suggested research model and the hypotheses through structural equation modeling. Regression analysis was carried out with SmartPLS to assess the path coefficient of the data collected for the model. The findings suggest that two of the key variables tested, thus self-efficacy and perceived usefulness of MLDs positively influenced students’ gratification and were statistically significant. However, two out of the three of the determinant variables of perceived usefulness (information seeking, and social connections) all had positive relations with students’ perceptions of gratification, and behavioral intentions towards MLDs. This study concludes that, information seeking, and social connections variables of the perceived usefulness, connote the positive relationships with students’ perceptions of gratification with MLDs. Furthermore, the findings suggest that students could improve behavioral intentions concerning the relevance of MLDs application in institutions of higher learning by applying varied MLDs at their disposal.

Sometimes, someone underestimates to check up skin disease unless the disease has affected his face or body in severe condition. The checkup fees for skin diseases are relatively expensive because they require a specialist. While the reach of society, in general, is the lower community. The purpose of this study is to bridge the gap between the patient and the examination of the disease based on the patient's skin image. The methods used in feature extraction and classification are Linear Discriminant Analysis LDA and Euclidean Distance respectively. LDA performs image feature extraction through a matrix operation process and distinguishing features in the same class and different classes. Classification will give the output of disease: abscess, eczema, ringworm, and urticaria. The accuracy results obtained are 80%. The next research is on adding features in the form of skin color so that it can be an input feature in the image as well as to improve its performance in the future. This application can be an alternative initial checkup for patients. It will detect the type of skin disease be suffered before consulting an expert.

Published: October 2022

La leptina es una hormona que participa en múltiples funciones biológicas. Esto es debido a la señalización que ejerce a nivel hipotalámico produciendo un estímulo de saciedad, balance en el gasto de energía, y un adecuado control del peso corporal. En los últimos años, se ha reportado un aumento en la mortalidad asociada con obesidad en población mexicana, posicionando a esta enfermedad como una de las principales causas, debido al desarrollo de comorbilidades asociadas a su patología. Se ha estudiado la participación de la leptina como una hormona pleiotrópica con propiedades cruciales para el desarrollo de sobrepeso y obesidad. Se ha observado que las alteraciones en su receptor predisponen a una resistencia a la leptina condicionando una respuesta pobre en la estimulación de la saciedad y, a su vez, un aumento en el consumo de alimentos. Otros estudios sugieren que las dietas con un alto contenido calórico producen una hiperactivación en la corteza cerebral asociada al sentido del gusto, generando un estímulo de recompensa que induce a un mayor consumo de alimentos, llevando paulatinamente a un incremento del tejido adiposo en el organismo. Investigaciones realizadas mediante la aplicación de leptina exógena en ratones han registrado una disminución transitoria del peso corporal con una disminución en el consumo de alimentos. Por estas razones, es importante describir y analizar la participación de la leptina en las señalizaciones neuroendocrinas de la obesidad, obteniendo una mayor comprensión y entendimiento de la enfermedad. El presente manuscrito pretende describir este tema con fines educativos.
What makes groups emotional?
Authors: Goldenberg Amit
Published: October 2022

When people experience emotions in a group, their emotions tend to have stronger intensity and to last longer, why is that? This question has occupied thinkers throughout history and with the use of digital media it is even more pressing today. Historically, attention has mainly focused on processes driven by the way emotions are shared between people via emotional interactions. While interactions are a major driver of group emotionality, I review empirical findings that suggest that understanding group emotionality requires a broader view which integrates two additional processes: how emotions unfold within the social infrastructure in which they are shared, and how these processes are affected by people’s cognition about emotions. I propose to summarize the literature using an infrastructure, cognition, interaction framework that contributes to a broader understanding of group emotionality, which should improve our ability to predict group emotionality and to change these emotions when they are undesired.
The Openscapes Flywheel: A framework for managers to facilitate and scale inclusive Open science practices
Authors: Robinson Erin , Stewart Lowndes Julia
Published: October 2022

Solutions to large-scale environmental and social challenges require radical collaboration that blends technology and people — and the Open science movement is answering that call by transforming how we work together. While often the focus is on data, publications, code, software developers, and researchers, the transition to Open involves investment across agencies and organizations of all kinds. One critical and often-overlooked part of transitioning to Open is that it requires support from managers and leadership, who do not need to be Open science experts but who can imagine the return on investment and support their teams through time and resources to learn new skills and technologies, take risks, and even fail through the process. In this paper we describe our work developing the Openscapes Flywheel with NASA Earth science data centers, using the concept where transformations occur from relentlessly pushing a giant, heavy flywheel that builds momentum over time. We offer three practical ways managers can support their teams and grow morale and technical capacity across their organizations: (1) Engage bright spots, through welcoming them and creating space and place; (2) Empower a learning culture through, investing in learning and trust and working openly (3) Amplify Open science leaders, through leveraging the common and inspiring the bigger movement. Together these lessons create kinder and more inclusive organizations that are more resilient as data volumes increase and software evolve, and dispel the hero myth of science. Engaging, empowering and amplifying efforts to support people while modernizing our workforce is the way that we will meet the world’s greatest challenges, from climate change to social justice to democracy. We can already see how working this way increases inclusion, reproducibility, and resilience within and across government, academic, and non-profit organizations, and are hopeful for what we can do together in growing this movement.

Relativistic energy is a material that is considered difficult by students because the general solution takes quite a long time. This is based on the results of interviews with students of SMAN Plus Sukowono. The magic number method is a method using the Pythagorean principle through special numbers that are often encountered in relativistic energy problems. The purpose of the research was to obtain data on student responses to the magic number method as an alternative solution to the relativistic kinetic energy problem that makes it easier for students to solve relativistic energy problems. The research method used by the researcher is the survey research method with descriptive analysis. The respondents used were 28 students of class XI MIPA SMAN Plus Sukowono and used an assessment instrument in the form of a response questionnaire. Student response questionnaires were compiled based on Stellen M. Chafe's theory which was based on the cognitive, affective, and conative dimensions. The results of the research on student responses to the magic number method as an alternative solution to the problem of solving relativistic kinetic energy problems obtained percentage data on the cognitive dimension of 72.93% in the positive category, the affective dimension of 80.63% in the very positive category and the cognitive dimension in 75% in the positive category. The average of the overall response dimensions is 76.19% in the positive category. This research can be concluded that the magic number method can be used in physics learning the theory of relativity.

Published: October 2022

The Covid-19 pandemic presents a great challenge worldwide on how to manage a global health crisis. While some governments have been more successful than others in trying to cope with the crisis, several politicians presented conflicting arguments in regard the spread of coronavirus. Between the implementation of harsh sanitary measures to the mistrust of scientific data and conspiracy theory, but also criticism against European and international organisations, the Polish public had witnessed different reactions from politicians vis-à-vis the use of science throughout the crisis. This chapter focuses on the representation of the Covid-19 pandemic in a selection of Polish weekly magazines close to the right-wing populist political coalition in power, United Right. We aim at investigating the construction of the Polish populist discourse on the Covid-19 crisis, focusing on how the crisis is represented, how the people – as the main recipient of populist discourse – is addressed, and finally how science is used.

Authors:   University of Warsaw, Afelt Aneta
Published: October 2022

The SARS-CoV-2 virus is the third human coronavirus detected in the 21st century. It was only a few weeks between the first cases of atypical severe respiratory disease in Wuhan, China (late 2019), and the identification of the virus, its genetic structure and the development of a PCR test (January 2020). What processes and mechanisms at the interface between nature and human activities are responsible for the emergence of the new coronavirus? How was it possible that the virus has spread among humans so quickly? Is the spread of the virus limited to the human population only? How do Anthropocene conditions favor pathogens such as SARSCoV-2? From a scientific point of view, the emergence of a new coronavirus is not surprising.

La pandémie de Covid-19, un outil discursif au service des objectifs géopolitiques de l’Initiative des Trois Mers
Authors:   University of Vincennes Paris 8, Ramdani Sami
Published: October 2022

The Three Seas Initiative (3SI) is a platform for political cooperation created in 2016 that brings together twelve Central and Eastern European countries. The objective of this organization is to address the gap in economic development with Western Europe and to strengthen regional resilience against actors such as Russia and China through the development of infrastructure in the sectors of energy, telecommunications and transport. In September 2020, the 3SI’s development policy was encouraged by a report from the International Monetary Fund (IMF) which sees it as a solution for reviving the European economy following the Covid-19 pandemic. Consequently, the pandemic becomes an argument for the 3SI to attract capital to the projects it carries. However, the projects supported by the 3SI are not only structured by economic objectives but also by strategic objectives. We will illustrate the geopolitical dimension of the 3SI with a case study: the North-South Gas Corridor.

The analysis aimed to answer the following questions: (1) what can change as a result of the pandemic, and what will not? (2) what scenarios from an economist’s point of view can we draw for Poland for the coming months? (3) how will relations with the countries of Central Europe develop? Covid-19 and the solutions applied to curb the pandemic have a strong impact on the acceleration of certain inevitable changes in the economic sphere or in the technologies and organizational solutions used. This problem constitutes an area of analysis in its own right and leads to the presentation of scenarios for the future.
Comment concevoir le discours expert lors de la pandémie de Covid-19. Quelques éléments de la méthodologie inspirée de l’École française d’analyse du discours
Authors:   University of Warsaw, Jaworska Alicja
Published: October 2022

This chapter aims to provide some elements of the definition of expert discourse during the Covid-19 pandemic from the point of view of the French school of discourse analysis. The expert discourse would be one of the elements in the construction of this media event (Moirand 2007); it would be the one that comes from the legitimate expert or the one that results from the expertise activity. But at the same time, it is subordinated to the conditions of media communication (Charaudeau 2005; Garric, Léglise 2012). The fragments of expert discourse are chosen by the media not to transmit knowledge, but to construct content corresponding to different aims. The figure of expert, whose legitimacy comes from social relations of authority, from the distinction between what is scientific and what is ordinary, as well as his credibility are built in discourse.

Published: October 2022

An investigation was conducted to assess the potential of water-stabilized plasma (WSP) spraying for applying protective boron carbide coatings to fusion reactor components. This paper describes how test samples were produced and how coating quality was determined. The authors sprayed boron carbide powder onto steel and stainless steel substrates using different powder feeding and spraying distances, substrate preheat temperatures, and carrier gases. They also investigated methods for optimizing the plasma jet and improving coating adhesion. The boron carbide coatings were characterized based on phase composition, porosity, oxygen content, and flexural strength. Paper includes a German-language abstract.

Authors: Reignier C. , Sturgeon A. , Lee D. , De Wet D.
Published: October 2022

This work evaluates HVOF sprayed cermet coatings as an alternative to galvanic hard chrome plating for applications requiring corrosion and wear protection. WC-10Co-4Cr layers were deposited on different types of steel using commercially available HVOF systems. The coatings were then assessed based on their friction, wear, adhesion, and corrosion behaviors, which are shown to compare favorably with those achieved using a commercial hard chrome plating system. The paper also sheds light on how salt spray attacks protective surface layers at the edges, causing corrosion that propagates along the interface with the substrate. When coating edges were protected, exposure to salt spray atmospheres did not jeopardize the bond strength of any (cermet or chrome) coating tested. Paper includes a German-language abstract.

Effect of Surface Morphology of Substrate on Flattening Behavior of Freely Fallen Metal Droplet
Authors: Fukumoto M. , Nishiyama T. , Nishioka E.
Published: October 2022

Most metallic and ceramic splats exhibit temperature-dependent behavior when they strike a metal substrate and assume a shape that suggests temperature-dependent wetting properties. In this study, the authors investigate the relationship between high-temperature oxidation, substrate morphology, and the flattening behavior of free-falling droplets. Substrate surfaces are examined by means of atomic force microscopy, which shows that changes in morphology of just a few nanometers can have an effect on flattening behavior.

Zusammenhänge zwischen dem Gefüge und den Eigenschaften der TiC-haltigen Spritzschichten (Correlations in the Microstructure and Properties of TiC-Containing Thermal Spray Coatings)
Authors: Azarova T. , Vityaz P. , Wielage B. , Steinhäuser S. , Podlesak H.
Published: October 2022

The aim of this work is to determine how to control the microstructure and tribological properties of HVOF-sprayed TiC composite coatings. The powders used in the study were made by the SHS process and contained a mixture of TiC and either FeCr20Ni10 or FeCr18Ni15Mo3, which serve as a binder and give the sprayed coatings additional corrosion resistance. The composites produced were assessed based on metallographic examination and wear testing. The results show how the structure of the SHS powder changes due to the injection molding process and how the tribological properties of the HVOF layers are influenced by spraying conditions and the formation of mixed carbides.

Observation of Microstructure in Thermal Barrier Coatings Prepared by Laser Hybrid Spraying Process Using Fluorescent Dye Infiltration Technique
Authors: Chwa S.O. , Ohmori A.
Published: October 2022

Laser post-treatments and plasma-laser hybrid spraying processes are increasingly being used to extend the service life of thermal barrier coatings by making them more resistant to thermal shock. Studies show that laser-induced cracking plays a major role in the improvements achieved. The investigation of such modified layers can be difficult, however, because the stresses associated with metallographic procedures can alter the structural features of segmented microcracks and damage the specimen. In this research, laser treated and laser hybrid sprayed thermal barrier coatings are vacuum impregnated with fluorescent epoxy resins in order to study their microstructure and its relationship with thermal shock resistance. All relevant processes are described along with crack formation behaviors. Paper includes a German-language abstract.
