[edit] A list of types of Scientific modelling

The next list is in a recent change rather ("vernaggeld") made invisable (some google-rates have been added, with term written with "l"//"ll"):

  1. Climate modelling - 424.000 // 301.000
  2. Data modelling - 1.650.000 // 636.000
  3. Ecological modelling - 183.000 // 543.000
  4. Economical modelling - 365.000 // 493.000
  5. Climate modelling - 424.000 // 310.000
  6. Futures studies
  7. Geologic modelling
  8. Graphical modelling
  9. Hydrographical modelling
  10. Hydrological modelling
  11. Hydrogeological modelling
  12. Mathematical modelling
  13. Medical modelling
  14. Meteorological modelling
  15. Modelling in Epidemiology
  16. Modelling of scientific inquiry
  17. Molecular modelling
  18. Ocean modelling
  19. Policy modelling
  20. Simulation
  21. Software modelling
  22. Statistical modelling
  23. Stochastical modelling
  24. System dynamics

This list represents the titles of some 40 magazines about scientific modelling which offer all kinds of international forums. And every item in this list has an link to the place were more information can be found. - Mdd 14:02, 5 October 2007 (UTC)

[edit] The original listing back

Now this list was undressed for what reasons, but I restored it. This was not a see also section, where a list is given from all items in Wikipedia related to the subject. This is a lst of existing forms of scientific modelling in reality. Maybe I should have explained this better. However recently I started transforming this listing into text.. and I have got any further yet. I hope I have explained my actions. - Mdd 14:12, 5 October 2007 (UTC)

please see Wikipedia:Piped link#Use. The purpose of piped links is NOT to provide uniformity in a list. It is to allow an in-text link to fit grammatically into the sentence. The article include several that have little or nothing to do with scientific modelling. DCDuring 15:27, 5 October 2007 (UTC)

I have read every word of the Wikipedia:Piped link#Use, and it doesn't forbit what I did. And you are trying to turns things around here. This is a list of forms of scientific modelling... which I originally extracted from reality. I used the piped link to show, what Wikipedia has to offer about every type of modelling.

Now as I said, I'm in the process of writting a section about every type of modelling. If you state that several types have little or nothing to do with scientific modelling, I am very interested. Above is a list of 24 types. Could you tell me which types you mean and why? - Mdd 18:02, 5 October 2007 (UTC)

[edit] The listing of types of scientific modelling

I started adding some google rates at the types of scientific modelling, which gives a first indication about how notable these subjects are. - Mdd 13:37, 8 October 2007 (UTC)

[edit] Overview

Plagiarism!? At least in the "Overview" section, most of the text seems lifted directly by the paper "Modelling as a Discipline" by Silvert (2000). However, a citation only comes at the end of the section. No time to fix, but if anyone's able, it's on the to-do list.

Thanks. At the moment there are two references in this section. These two references indeed confirm you suggestion. The problem here is not so much, that that Silvert is referenced, but that no more sources are referenced to. This is a problem which often occur in Wikipedia articles that are just a beginning. I will try to fix this soone. -- Mdd (talk) 10:11, 12 April 2008 (UTC)
Although you do have a point, I want to respond to question if here there is a case of plagiarism. I have a few things in response.
  • "..most of the text seems lifted directly by the paper...". The text is available on line an anyone can check that this txt is no directly lifted, but slightly rewritten into the general introduction that fitts this Wikipedia context.
  • A lot o similarities remain because both texts have the same purpose to give a general introduction on scientific modelling.
  • I have selected this particulair text out of the dozends of books and articles I read about this subject.
But as I stated before, this article is still in a premature state. And I am going to work on that. Last but not least. I don't know if one could call this situation a type of plagiarism in the first place, because the source is clearly mentioned, the text is clearly rewritten, and it is only a general introduction of known knowledge. Not some bright original ideas which are completely copied here. In Wikipedia we have rules about copyright infringement. I will look into this some more. And I will rewrite the introduction some more sone. -- Mdd (talk) 14:11, 12 April 2008 (UTC)

[edit] Examples removed

I removed the folowing examples.

    • Model of a particle: in a potential field. In this model we consider a particle as being a point of mass m that describes a trajectory modelled by a function x: R ? R3 given its coordinates in space as a function of time. The potential field is given by a function V:R3 ? R and the trajectory is a solution of the differential equation
m \frac{d^2}{dt^2} x(t) = - \operatorname{grad} V(x(t)).
Note this model assumes that the particle is a point mass, which is certainly known to be false in many cases where we use the model, e.g. when we use it as a model of planetary motion.
    • Model of rational behavior for a consumer. In this model we assume a consumer faces a choice of n commodities labelled 1,2,...,n each with a market price p1, p2,..., pn. The consumer is assumed to have a cardinal utility function U (cardinal in the sense that it assigns numerical values to utilities), depending on the amounts of commodities x1, x2,..., xn consumed. The model further assumes that the consumer has a budget M which she uses to purchase a vector x1, x2,..., xn in such a way as to maximize U(x1, x2,..., xn). The problem of rational behavior in this model then becomes one of constrained maximization, that is maximize
U(x_1,x_2,\ldots, x_n)
subject to
\sum_{i=1}^n p_i x_i = M.
This model has been used in model of general equilibrium theory, particularly to show existence and Pareto optimality of economic equilibria. However, the fact that this particular formulation assigns numerical values to levels of satisfaction is a source of criticism. But this is not an essential ingredient of the theory and again, the model is an idealization.
    • Myers-Briggs personality type. Myers-Briggs Type Indicator is a technique that claims to produce a representation of a person's preferences, using four scales. These scales can be combined in various ways to produce 16 personality types. Types are typically denoted by four letters — for example, INTJ (introverted intuition with extroverted thinking) — to represent a person's preferences. This model is claimed by CPP (formerly known as Consulting Psychologists Press, Inc.) to produce a good predictor of a person's career and marriage partner preference. It should be pointed out, see [1], that there is considerable disagreement among psychologists on whether this assessment technique (and the implied idealized personality model) is of any value.
    • Model of political contagion. Some versions of this model are sometimes referred to as the domino theory. In the broadest possible terms, according to this model, political movements that take hold in one country are likely to spread to geographically neighboring ones. This model is surprisingly popular, although as it stands, it is extremely impoverished conceptually, saying nothing about the type of political movement, the degree of geographical proximity, the time scale at which these events take place, etc.

[edit] Further comment

These examples are removed because:

  • No of these items are examples of scientific modelling.
  • These examples aren't even examples of genaral types of scientific models, but a random list of some specific types of models. Wikipedia offers articles about hunderds of those items.
  • The article itselve gives a list of the more general types of scientific modelling
