TO ALLOW OR NOT TO ALLOW MOBILE PHONES IN THE UNIVERSITY CLASS?! - A PLEA FOR EDUCATED (RELATIVE) PERMISSIVENESS
Authors: Catelly Yolandamirela 
Published: February 2023

The general background against which this study is proposed refers to the controversial issue of allowing or not students to have or use mobile telephones in class, with quite numerous voices claiming that it is detrimental to the education quality, and rather few members of the educational profession pleading in favour of it - certainly with sound arguments, such as: ensuring its use for learning purposes only, and even (re)designing teaching materials to include/encourage such functions. Therefore, given the fact that the context taken into account for the proposed research project is that of tertiary engineering students learning to become Computer Science specialists, with over 95% of them in possession of flagship phones and having the skills to make full use of such equipment, the aim of the paper is a multiple one, viz. to: (i) localize the worldwide debate on the degree of permissiveness vs interdiction as to mobile phone use in class, (ii) take stock of both students’ and teachers’ views in the described context – (iii) alongside with a hidden agenda of pleading in favour of an educated, i.e. psycho-pedagogically well justified manner, change of mentality and attitude in both categories of actors within the instructional process, as far as mobile phone uses are concerned in and/or outside the classroom. A critical review of major viewpoints on the advantages and disadvantages of allowing students to have/use mobile phones in class, as well as the diachronic perspective of the teachers’ openness in this respect have created the starting point in investigating the current situation in the author’s educational context. Hence, the approach proposed here hypothesizes that, by getting both students and teachers to answer research instruments such as questionnaires, interviews and focus groups, reflection on the topic is stimulated and, consequently, a change (even if minor) in the degree of the instructors’ educated purposeful permissiveness is encouraged. Similarly, increased awareness of the real benefits of mobile phones used in class mainly for study purposes can contribute to the students’ diminishing of their non-educational uses of this almost indispensable device. Data collected are presented and discussed; they tend to point out to the need for an educated change of mentality in this respect.
THE ADVANTAGES OF GAMIFICATION AND GAME-BASED LEARNING AND THEIR BENEFITS IN THE DEVELOPMENT OF EDUCATION
Authors: Nistor Gabriel calin , Iacob Adrian 
Published: February 2023

In the United States, gamification is used in education for more than 10 years. Gamification is a procedure that employs certain game specific elements in different fields like education, health, sport or human resources. This process is known as "Human-Focused Design", as opposed to "Function-Focused Design." It's a design process that optimizes for human motivation in a system, as opposed to pure efficiency. Most systems are "function-focused", designed to get the job done quickly. This is like a factory that assumes its workers will do their jobs because they are required to. However, Human-Focused Design remembers that people in a system have feelings, insecurities, and reasons why they want or do not want to do certain things, and therefore optimizes for their feelings, motivations, and engagement. Since games have spent decades learning how to master motivation and engagement, we are now learning from games, and that is why we call it Gamification. Take for example Duolingo, a massive online collaboration which combines a free language-learning website with a paid crowdsourced text translation platform. The service is designed so that students can learn a given language online, while helping to translate websites and documents. The traditional motivational methods are less and less efficient and thus the companies are forced towards more attractive and innovative methods, fit for the psychological profile of the current generation, a generation raised and schooled in close connection with the technological progress. European Union started to show interest for these aspects, as proven by the Game-Based Learning and Gamification training course that was organized in Spain by the means of a European Commission project.

Published: February 2023

Over time, posture has been a determining factor in the evolution of the human race, making the transition from quadruped to bipedal. This transition has brought changes in the mio-arthro-kinetic system, both structural changes in the vertebral column by altering the curves and functional changes, in the position of the general weight center, the supporting polygon, the pressure exerted within the supporting polygon, the projection of the center of gravity in the supporting polygon etc. This position has been studied and well determined in the speciality literature (functionally, biomechanical, anatomical, etc.), but in the last decade we have seen changes in this position, changes that can be registered with posturology at the level of the supportive surface and namely in the planting region.	The study was conducted on a number of 50 female students in the first year. All students benefited from a posturological assessment, performed from the bipedal position with a posturotest, and also an anthropometric evaluation. The inventory data were taken, statistically processed and compared with the data in the literature. The study helped identify the problems faced by the subjects up to this level, problems that led to a poor posture. The results of the study are shown through figures and pressure maps that will facilitate their understanding by the user. Subsequent follow-up is done by developing a protocol to eliminate identified problems, tracking students over a one-year studio, and reevaluating them to see if the elimination of the problems has helped remedy the vicious position. This approach will allow validate the protocol and will help at its improvement. On the other hand, preserving an archive with templates of evolution of pressure maps will allow the user to evaluate the quality of postural improvement of the patient and as an educational tool for the analysis of plantar pressure maps.
Dog Eat Dog: Balancing Network Effects and Differentiation in a Digital Platform Merger
Authors: Farronato Chiara , Fong Jessica , Fradkin Andrey 
Published: February 2023

Network effects are often used to justify platform strategies such as acquisitions and subsidies that aggregate users to a single dominant platform. However, when users have heterogeneous preferences, a single platform may not be as effective as multiple platforms from both a strategic perspective and an antitrust perspective. We study the role of network effects and platform differentiation in the context of a merger between the two largest platforms for pet-sitting services. To obtain causal estimates of network effects, we leverage geographic variation in premerger market shares and employ a difference-in-differences approach. Our results reveal that although users of the acquiring platform benefit from the merger thanks to network effects, those of the acquired platform are comparatively worse off because their preferred option is removed. Network effects and differentiation offset each other such that at the market level, users are not substantially better off with a combined platform than with two separate platforms. These findings have strategic and regulatory implications as well as highlight the importance of platform differentiation even in the presence of network effects.

Abstract. Salinity plays an important role for phenomenon identification of upwelling and downwelling. Upwelling that occurs in the Indian Ocean south of Java to South of Bali is influenced by monsoons, ENSO (El Nino Southern Oscillation) and IOD (Indian Dipole Oscillation Mode). Upwelling and downwelling patterns based on vertical structure of salinity and its seasonal variability within seven years (2004 to 2010) is studied here. Argo Float dataset is used in this study, processed by Ferret software for a vertical schematic model, and Pearson correlated with IOD and SOI indexes. The aim of this study is to obtain the pattern of upwelling and downwelling based on profile of seasonal salinity during the period 2004-2010 in Indian Ocean south of Java – Bali and correlated with ENSO and IOD. Further discussion on upwellling is provided since it is more important to the fisheries activity. Result shows an intensive upwelling phenomenon occurs at 110°E correlated with fishing ground area.

ObjectivesThere has been a steady increase in the number of studies of the complex relationship between glucose and electrical cardiac activity which use simultaneous continuous glucose monitors (CGM) and continuous electrocardiogram (ECG). However, data collected on the same individual tend to be similar (yielding correlated or dependent data) and require analyses that take into account that correlation. Many opt for simplified techniques such as calculating one measure from the data collected and analyse one observation per subject. These simplified methods may yield inconsistent and biased results in some instances. In this systematic review, we aim to examine the adequacy of the statistical analyses performed in such studies and make recommendations for future studies.Research questionsWhat are the objectives of studies collecting simultaneous CGM and ECG data? Do methods used in analysing CGM and continuous ECG data fully optimise the data collected?DesignSystematic review.Data sourcesPubMed and Web of Science.MethodsA comprehensive search of the PubMed and Web of Science databases to June 2022 was performed. Studies utilising CGM and continuous ECG simultaneously in people with diabetes were included. We extracted information about study objectives, technologies used to collect data and statistical analysis methods used for analysis. Reporting was done following PRISMA guidelines.ResultsOut of 118 publications screened, a total of 31 studies met the inclusion criteria. There was a diverse array of study objectives, with only two studies exploring the same exposure-outcome relationship, allowing only qualitative analysis. Only seven studies (23%) incorporated methods which fully utilised the study data using methods that yield the correct power and minimize type I error rate. The rest (77%) used analyses that summarise the data first before analysis and/or totally ignored data dependency. Of those who applied more advanced methods, one study performed both simple and correct analyses and found that ignoring data structure resulted in no association whilst controlling for repeated measures yielded a significant relationship.ConclusionMost studies underutilised statistical methods suitable for analysis of dynamic continuous data, potentially attenuating their statistical power and overall conclusions. We recommend that aggregated data be used only as exploratory analysis, while primary analysis should use methods applied to the raw data such as mixed models or functional data analyses. These methods are widely available in many free, open source software applications.
