Demonstrating - Science topic

how can we create these plots? a 3-dimensional look and showing strength with colour, which software does create these pictures?

How could I find a hybrid conference (in-present + online) to submit a demo paper in data science/data management? I tried searching using WikiCFP, Google search, and the IEEE conference search engine with no luck. These search engines will help find one aspect of the conference (hybrid or accept demo papers), but I cannot match both requirements.

Note: I need to present my demo paper online without traveling.

Any help is appreciated.

As we know, in the research of machine learning or deep learning, training set and test set should be divided. The work of the training set is to train the model, while the function of the test set is to test the model on the trained model.However, I have seen some articles that test a model using the training set itself in order to demonstrate the effect of a model. Is there a problem with such logic?

The current climate protests are planned for at least 107 countries this friday (24.5). My research team in planning on doing ethnographical observations and interviews at the demonstrations in Oslo, Norway. Is anyone else looking at this worldwide phenomenon?

If so, what is your focus? Would love to discuss methodologies used to investigate this!

We come from cultural, and community psychology, so thats broadly the kind of focus we would use. Planning a mixed-methods project.

Diminishing Returns Concept: At a certain point , increasing the amount of input (e.g. effort) will still lead to an increase in output but at a rate less than before.

I'm looking for resources (videos, pictures, games, activities, articles etc..) that would explain or illustrate this concept in an engaging and/or simple way especially to a lay audience. It could be a straightforward explanation like this A video explaining the concept "Co-relation does not equal causation"

https://www.youtube.com/watch?v=gxSUqr3ouYA

where the original intent of the video is to explain this concept. Or ,You can be creative; this illustration does not need to be originally made to explain this concept. The analogy can be made independently of the original intention of the resource. For example, if the concept is flexibility in your career, I can find a video of a person demonstrating physical flexibility even though the original intent of the video is not about career flexibility. (For more on what I mean by concept-demonstrating resources, see https://www.researchgate.net/post/List_of_Concept-Demonstrating_Resources

Please put your suggestion in the comments section below.

Have anyone used these two theories in the same research paper?

We have done a theory of planned behaviour analysis, and plan to demonstrate the finding in the theory of buying behaviour (Howard & Sheth model).

As we read reports every year, every month, of most unfortunate/ tragic 'stampede' cases, administrators remain ever clueless about the 'number of people' who might gather in the venues or places, for 'planned' and 'unplanned' events. In India and abroad, it has become a regular phenomenon to loose some of the members (of our own mankind), attending such events. Religious congregations/ assemblies and gatherings (like the cases of Kumbha-mela of North India, Ratha-Yatra/ Car-festival of Odisha, Sabarimala in South India; etc) or political demonstrations (occurring recently throughout the Middle-East, East-Asia, China and now in Delhi), where hundreds of thousands of people can congregate in just a few hours, are just a few of such challenges for local administrators.

But if we see and study such events as a research problem, we see that sometimes people gather all of a sudden (unplanned, as we find from the attached report on a most recent stampede, which happened in Mumbai, India).

Is there any study or finding, linking the 'degree of seriousness of news' to the 'rate of arrival' of people, and 'estimate of the maximum possible gathering' (considering the finite nature of the 'source- population', how ever large it may be)? [Both for 'planned' and un-planned' gatherings.]
