In September 2021, El Salvador adopted Bitcoin, the largest cryptocurrency, as legal tender. The highly volatile Bitcoin token, based on decentralized ledger technology, has been declared the national currency, parallel to the current legal tender in El Salvador - the U.S. dollar. Authorities have launched a mobile app called Chivo Wallet, enabling citizens to send and receive BTC, convert BTC into USD and withdraw USD from special ATMs. Will this move lead to greater financial inclusion, especially for the still fairly large portion of El Salvador's population that does not have bank accounts? Or is it rather a very risky project leading to financial instability in the Salvadoran economy?
Relevant answer
I believe that the main advantages of the Bitcoin Act are the reduction of fees for sending remittances from the US and that it will encourage financial inclusion (the use of a smartphone is broader than banking services) and innovation in this sector. However, there is a great macroeconomic risk because it may hinder negotiations with the IMF and the high volatility generates uncertainty and problems of economic calculation, but the problem, in my opinion, is articles 7 and 13, which establish the forced course of this digital asset. On the other hand, the trust fund that has been created with public resources could be emptied if bitcoin depreciates (although I don't think this will happen) and economic agents exchange their bitcoins for dollars.

Lot of mobile apps are available in 'play stores', , like reading soil temperature, leaf temperature, moisture, physiological parameters etc. Whether for scientific crop research such 'mobile apps'can be used?

Answer
I have read several articles on the use of the app, for example, Canopeo App, even in scientific trials and that value obtained from crop coverage, for example, should always be corrected for the planting width and other variables. It is a tool, but it must still be corrected and determine if the data actually adjusts to reality.

I am currently choosing a topic for my PhD thesis and I have 2 topic ideas but I am a little confused on which shall I proceed with and which topic would be useful and relevant.
One is regarding incorporating AI in cybersecurity and another idea is to do on something related to Mobile App Development (Hybrid app development (security & management), Low code - No code, or using AI for mobile app development).
Are there any other hot topics that I can look into, please do suggest. Thank you so much for your time.
Would really appreciate your thoughts on this :)

Answer
You are interested in AI and Cyber Security, which are both wide, Cyber Security wider and not disjoint. The presented related topic, therefore, appears rather wide. A topic should be focused on solving identified existing deficiencies. Identify certain problems in an area of cyber security that an area of AI would address properly in a new way. Your supervisors would be of better help.

I have used Bookwidgets (School paid for it). It is useful and it actually can be helpful for formative and summative assessment. Google Forms has been useful for short quizzes. Edpuzzle and Kahoot are also used, but not that often. Kahoot and Socrative tend to lose their "assessment" feeling on learners, as they're heavily gamified.

In Software Engineering the UML is considered a standard way in design of the system. What will be the best in designing the mobile applications?
Relevant answer
Answer
In my experience, having used and taught UML extensively, it's most useful once you have a clear idea of the details of your app. If you are already at that stage, then it can be very helpful. But much of the detail in most mobile apps is in the visual presentation and user experience. Until you have that well in hand, UML won't be very useful. You can use a combination of paper/whiteboard mockups to solicit feedback from representative users, then perhaps move on to a prototyping environment to work out the dynamics before worrying much about the design of the underlying software. In many cases, once you have worked out the user experience and the data needed to present it and collect user input, you may find that the extra step of using UML is just not necessary or helpful.

I'm currently working towards creating an app that implanents a CNN in a computer vision context. Ideally I want to train the model seperarely, and then be able to deploy it in OpenCV in Visual Studios (2017) for prototyping, and then in a mobile app as the actual product. What's the best way of achieving this?
Currently it seems like I have to use Tensorflow amd export the model to a server which I would call from Visual Studios or the app. Is there a better or easier way of doing this?
Thanks.
Relevant answer
Answer
CNN is just an algorithm for a model, R, tensorflow...are framework that implement that model. In fact you can implement it in many languages but it's time consuming to write everything from scratch.
I think the easiest way is to use it as a service, meaning that your application only deals with collecting data. Send the data to server and then get back the result.

Answer
Social networking applications have become an inescapable part of our lives. The power of social networking is such that the number of worldwide monthly active users is expected to reach some 3 billion by 2021. Yes, that’s around a third of the earth’s entire population. Big and popular social networks such as Facebook and Twitter aren’t going anywhere. But people also use niche social networks for different needs. The idea of building new social interactions is great, so it would be useful to learn a bit about the technology stacks that social networks rely on. Because no matter who your target audience is, your social network should offer a great user experience and provide users with core features.

I am currently doing a study of Second language acquisition through the use of a mobile app.
For that purpose, I have gathered a multitude of independent variables, which I intenteded to use in a multiple regression analysis, using the learning gain scores of the participants as the dependent variable.
However, all the variables related to the use of the app (Time spent, words learned, number of days accessed, etc.) presented me with a dire problem in relation to multicollinearity (they all have 0,1>tolerance, as well as 10<VIF).
It is logical, that all these variables are collinear, as all of them stems for the app being used.
Because of this, is it possible for me to pick out 1 of the independent variables related to app usage (e.g. "Total time spent in app"), to represent app usage in general, and then proceed with the regression analysis?
Thank you in advance.
Relevant answer
Answer
You should look at the correlation matrix for the independent variables. Then , if the variables are highly correlated,select the one which is the most clinically relevant or one which is of scientific interest as a potential independent risk factor (from previous studies). If you are looking to develop a prediction model you may wish to include as the representative of the correlated variables the one which is most easily or economically obtainable in any given hospital or field  situation . I assume from your question that this is straight multiple linear regression with just  AKI as the one dependent variable. Multivariate regression strictly refers to a more complex model with multiple dependent variables as well.

la UNESCO propone estudiar la posibilidad de crear programas de educación a distancia para relevar buenas prácticas en el diseño, adaptación y uso de recursos educativos abiertos y ofrecer asesorías a los países miembros, principalmente a los en vías de desarrollo, para que amplíen su oferta de programas en educación superior virtual.
Se debe hacer uso de la blended education (aprendizaje combinado) es un enfoque de la educación que combina materiales educativos en línea y oportunidades para la interacción en línea con los métodos tradicionales de aula basados ​​en el lugar. Requiere la presencia física tanto del maestro como del estudiante, con algunos elementos de control del estudiante sobre el tiempo, el lugar, el camino o el ritmo. Si bien los estudiantes aún asisten a escuelas "físicas" con un maestro presente, las prácticas presenciales en el aula se combinan con actividades mediadas por computadora con respecto al contenido y la entrega. El aprendizaje combinado también se utiliza en entornos de desarrollo profesional y en la capacitación para el trabajo.
El aprendizaje combinado depende en gran medida del contexto, por lo tanto, es difícil encontrar una concepción universal de él. Algunos informes han afirmado que la falta de consenso sobre una definición difícil de aprendizaje combinado ha llevado a dificultades en la investigación sobre su efectividad. Sin embargo, un meta análisis de 2015 que históricamente analizó una revisión exhaustiva de los estudios de investigación basados ​​en la evidencia sobre el aprendizaje combinado, encontró elementos comunes en la definición de que el aprendizaje combinado "se consideraba una combinación de los modos tradicionales de instrucción (cara a cara) con en línea; modos de aprendizaje, basándose en la instrucción mediada por la tecnología, donde todos los participantes en el proceso de aprendizaje están separados por la distancia en algunas ocasiones ". Este informe también encontró que todos estos estudios basados ​​en evidencia concluyeron que el rendimiento de los estudiantes trajo consigo mayores experiencias de aprendizaje combinado en comparación con las experiencias de aprendizaje totalmente en línea o totalmente en persona. [1]
Un claro ejemplo de lo anterior es la entrega digital de aprendizaje combinado a través de la aplicación móvil Master-O, por Inspire One. La entrega digital de aprendizaje combinado en una aplicación móvil. El "aprendizaje combinado" a veces se usa en el mismo sentido del "aprendizaje personalizado" y la instrucción diferenciada.

I have proposed a new set of heuristics for evaluating the usability of mobile application's interfaces that are designed in a different language rather than English.
Currently, I am testing this set through a Heuristic Evaluation (HE) procedure. there is also another HE that is using Nielsen. So both heuristics sets are going to evaluate a sample of mobile apps. The obtained usability problems will be used to determine which set is better when it comes to evaluate mobile apps with non English interfaces.
How can I say that my heuristics scored better than Nielsen in term of the language differences, because Nielsen heuristics are broad and can detect so many problems, but may not be related to the language. So I need to ignore those which are not related to the language. Is there a method that can be used as a base line to differentiate the found problem based on the language context?
Thanks
Relevant answer
Answer
I don't think there is "a better" heuristic rule set. The set that fits the system under study the best, is the most preferable one. A rule set particular to your mobile application can be built following the application of both your heuristics and Nielsen rules. You can include the Nielsen rules that fit your system, and add rules more particular to your system (including the language aspect).
You can take a look at the paper below for similar approaches in building rule sets for heuristic evaluation.

Relevant answer
Answer
Hi Mona,
you could take a look onto growth curve modeling, where time intervals are represented in unevenly progressing "factor loadings" of a latent growth factor.
Actually, Daniel Wright 's suggestion of a multilevel approach is just a different outlet for this analysis and will result in almost identical results. The only difference is that a multilevel model assumes equal error variances of the measures across time and growth curve modeling does not (and you can test that).

Almost all of us know the concept of different sources of CAR-SHARING such as "UBER", "Blablacar", etc, and also about "BIKE-SHARING" or "BIKE-SHARING-SYSTEMS", those like normal rental city bike sharing systems in almost most modern cities, and also more recently "MOBIKEs"(where you can get and leave your bike just anywhere and not necessarily in specified stations); now the question or the challenge could be what if we make a combination of both these two new sharing-systems! Imagine you have a reliable account and identity in a trustworthy application on your smartphone, then you may borrow a bike from another user in another city or town of that same application by finding their location and availability time and fix that you will borrow their bike for a specific amount of time and when returning it back, the bike will be checked(by the owner) and if everything will be fine so you both will get some points(lender and borrower category points) through some evaluations and reviews. Now expand this network all over a country or maybe all over the world! thus in any new place, you can just have a rental bike through that big and growing network, that you may not necessarily pay for it(by having enough points) and there is no need to just make a new account to rent a bike from any specific local company in any other city where you may go!
Finally to make this idea become more realistic and feasible, what could be the possible challenges and problems, and how we may be able to overcome them?
Relevant answer
Answer
Thank you for the link Professor Willem K. Korthals Altes. Firstly I would have to say that at the very first time I was thinking about this idea, as also the title I could have somehow mentioned it by saying: all over a country or (probably) all over the world!! my primary concern was that there would be definitely different legislation between countries and even more globally, that to sum them up in one single privacy law(for the main application) could be very difficult or even unfeasible at all! With all the respect to the author Alexander Hanff's comments, as he also mentioned in his comments this is not the only way if an organisation or probably a country want to extract personal data and privacy via tracking us by sharing our personal information through the application, although it is also mandatory to make a balance between the privacy of the users from one hand, and increasing security of our real users rights through misuse of fake accounts from the other. Thus the reliable data should be obtained to make a real account.
Eventually the main idea and concept of my discussion from the very beginning was to create a network quite similar to Couch-surfing in the world of bikes! which companies and ideas like "Mobike" could be apart of it however not necessarily, where by adding the personal bikes of the users to merge them up all through one bigger network. Considering the privacy issue the possibility to make such a big network in the ideal case perhaps could be the EU for instance or similar ones, if we may want to expand the project beyond the borders of a single country!

I'm planning an intervention study which will involve participants tracking the types of activities they do and their timing (amongst some other components, to improve sleep). I'm looking for an app, or a choice of apps, which I could suggest participants use to record when they do certain things that are part of their routine, e.g. walked to corner shop, ate breakfast, phonecall, used internet. We will use this as part of the clinical baseline assessment to direct intervention, and for participants to track their progress on goals. I envisage something where each person can create a list of their regular activities and then press the button to say they did it at that time (done now? / enter the time?) to minimise the participant burden and make the recording of time activity took place more accurate. So, like an event marker on an actigraph but for more than one different activity.
Does anyone know of any such apps? I was wondering if any of the 'to do list' type apps record (and can display or export) the time the activity took place rather than just the fact that it was done.
I need to avoid anything which already has some form of intervention embedded within it. The simpler the better!

Sounds like something Open data kit ( ODK) can do . ODK is open source and its easy to setup . You can add all your activities and have a start time and end time for the activities .

There is a very broad range of possible scenarios how you could use mobile applications as a data collection tool in research. Depending on the research context, there's also a growing body of literature describing the methodological contraints in different domains that you could refer to.

I am in for my thesis to graduate and the topic is about branded mobile app. I want to integrate the model of Alnawas (2016) into the extended Expectation - Confirmation model (ECM) of Bhattacherjee (2001) by replacing the "Perceived Usefulness" by the "4 benefits of using branded apps".
I propose in my study that these 2 concepts explain the same thing, the benefits users gain from using an IS (Information system) while Alnawas model matches better in the context of branded apps. Furthermore, while the "Perceived Usefulness" was proposed to have positive association with Satisfaction in the ECM, the relationship between Satisfaction & the 4 benefits was also tested by Alnawas.
My teacher told me that it's difficult to replace 1 factor of an existing model by a group of factors like that, and suggested me to keep the "Perceived Usefulness" in my proposed model, together with the new benefit factors. After collecting the data, I will run CFA to test the construct and if there is a poor fit, I will have to reject the model and reconstruct a new one.
I would like to know if my direction is feasible and why my teacher advised me to keep the old factor in my new model (Is there any theory explaining that?). Also, are there other research papers that conducted in the same direction?
p.s: I'm quite new to this kind of research, no previous experience, so I would very appreciate if other researchers can explain this to me in details.

Dear Tran Nguyen,
in the research model development, I agree with the previous comments. It is a common method to adopt, combine, and.or adapt the previous models for developing the new ones in the social computing studies. It may relate to the context of the human behavior change for using new technologies. However, of course, the adoption, combination, and/or adaptation have to be justified clearly based on a reasonable assumption. The assumption itself is developed for representing the research phenomenon using the basic concepts/theories.
In this case, my point of view is that you propose a brand loyalty model about branded mobile app by adopting and integrating the Alnawas's (2016) model and the Bhattacherjee's (2001) ECM model, and replacing (adapting) the "Perceived Usefulness" by the "4 benefits of using branded apps."
In the context of the adoption, combination, and the adaptation points, it may reasonable; but you have to able to describe clearly assumptions of the above-mentioned points in terms of the brand loyalty model about branded mobile app.
My suggestion are:
First; please, identify the used concepts/theories behind the Alnawas (2016) and Bhattacherjee's (2001) studies and then develop a logical map of the adoption, integration, and the adaptation following to the brand loyalty issue of the branded mobile app. This is for expressing reasonably the validity point of your proposed model, how the model represent the real phenomenon of the study.
Second; please, elucidate the model development process. The clear demonstration of the process may helpful people to see transparently the process. It is in regard to the trust point of the model development study. I believe, both validity and trust issues are essential in the model development studies (Eddy et al., 2012).

Gamification, as you mentioned, is not one technique it is more about "learning from games" what makes them so engaging and motivating, using not only simple elements but "game-design elements in a non-game context" [1], meaning also mechanics, aesthetics and processes [2].
Motivation (and engagement) itself has it's theories. For example self-determination theory. There are theories focussing on the individuals needs, physical or psychological (content theories, e.g. [3]) and there are theories focussing on cognitive processes.
All of those approaches can be used to determine how to improve the usability of a system (and improve the user motivation) and to fit the users needs and requirements. To improve the user-motivation, it is key to understand the context of use, to analyse precisely what it is that motivates the user as an individual to enhance the correct motivational elements. Theories (gamification, psychology, motivation...) can be used to backup ideas and hypotheses for design decisions and can help us understand the underlying concepts of motivation and engagement. In the end, what motivates a user is determined by the users situation and context.

Different smartphone use differenct GNSS receivers. What is their static and dynamic accuracy?
Relevant answer
Answer
Dear Prof. Specht,
your reseach meets my interests since my colleagues and me are working on smartphone's GNSS capability together with students for geodetic purposes (students project).
You asked for the accuracy of different GNSS receiver types for different manufactures. The question is: On which kind of accuracy you are interested in? Positioning? Timing? Velocity? Are you interested in the overall P-N-T accuracy? There are also important points like stability and continuity of observation types like carrier phase and code phase (pseudorange) as well as the performance of the used/installed antenna.
From my geodetic point of view it is the optimal procedure to determine the precision and accuracy of your unit out of the raw data which your unit provides.
Current Android systems (up to Android 7) support to access the real raw-data like carrier phase, code phase (pseudo ranges) and signal-to-noise (C/N0) ratio. At least the carrier phase observation is highly interesting for using smart devices as smartphones in high precision positioning. Besides of classical SPP-Algorithms (single point positioning) the carrier phases allows you to use PPP (precise point positing).
Please find a list of how to access raw data in smartphones:
Here is a very intersting aticle on how the performance of different units could be evaluated:
Beside of this, if you have access to a smartphone which is capable to store GNSS raw data, you could use a RINEX logger app:
to store observations in an independent format (RINEX - receiver indepenent Eexchange format) for further post-processing.
I really recommend the remarks of Pawel Prestrzelski.
Perhaps, clarify which kind of observation type (carrier phase or code phase) you are using and for which observation type you like to calculate the accuracy and / or precision.
as recommended by Pawel Prestrzelski please really make use of the raw measurements that your unit possible provides. The preprocessed solutions (internal position solution etc.) are in most of the cases a rough/errorneous solution or a solution with furhter conditions, which are not reported transparently. Your device could be more accurate and precise, if your data is processed with own algorithms and stochastical models where you know and can control everything.
To compare the units and to evaluate the accuracy and precision, I suppose the following procedure:
static:
  • capture data for 24 hours (maybe repeat for 2-3 days) on a fixed, static, repeatable mounting,
  • take care of the entire conditions around the smartphone (location of antenna, where is the smartphone located during measurments, buildings etc.) and take possible obstructions into account
  • compare the continuity of code phases (pseudo ranges) and carrier phases, maybe you have also access to the doppler and the signal-to-noise ration (C/N0).
  • calculate your ow position solution algorithm.
In our project we use the following method, to evaluate the quality of smart devices:
kinematic:
  • RTK-unit for reference solution
  • record observation on trajectories (RINEX) with smartpone and simultanously with RTK-unit.
  • compare online quality of both trajectories (rough test only) and post-process both trajectories while the RTK-Trajectory will be your target trajectory.
  • process form these data the precision, accury and correctness of your trajectories captures with smart devices.
....furhtermore, applications like PPP-RTK are highly interesting for such approaches.
From my experiences and point of view, the accuracy and precision of your smart devices is (1) strongly depending on the quality of the observation data delivered by the units and (2) depending on the algorithms you use, to process your observation for Positioning, Navigation and Timing (PNT).
Hopefully my remarks assist you by answering your questions.
Best regards,

Users and companies have been changing their behavior/strategies towards mobile apps and social media, in prejudice of websites.
Social media is becoming increasingly important (some companies are not even bothering to build a website). Today, nearly 80% of business have a dedicated team, social media is now a standard operating procedure.
Sports stars, like Lionel Messi, Kobe Bryant and Cristiano Ronaldo, have left websites almost completely and are engaging with their fans via Instagram, Facebook and Twitter. The website they own is not devoted to the player itself or to sell products, but as a place to promote their social media profiles.
Another example is obsessee.com. obsessee.com has as its only function to connect to their various social media profiles. And there are other examples of brands that only exist solely on social media.
There are more than one million apps in major app stores, something like an app for any circumstance in our life. In the scientific literature, there are evidences that users prefer to use Mobile Applications instead of web browsing, and stores which have an app have more chances of selling their products than those who do not (Kang, Mun, & Johnson, 2015).
In China, WeChat app is becoming the dominant portal to the web. WeChat users can book doctor appointments, pay traffic fines, and call a cab all directly from the app. So in addition to not needing to visit a website, they do not even need to visit another app. (The ridesharing apps just integrate with WeChat, which acts as a hub.)
This evidence suggests a change in users’ behavior and companies’ strategy towards Websites, influenced by the increasing use of Social Media and Mobile Apps.
As a researcher, what do you think about this?
Why do you think users are changing their behavior?
Can you imagine this a problem to the future of websites due to its (probable) decreasing use?
