There exist various tools for desktop or web usability testing like Techsmith Morae. Even if companies like Techsmith propose to use their tools also for mobile usability testing these tools do not satisfy because they are not native for this application area. Does somebody know an app or a tool which fits this need well? Who has experience in this area?

Answer
You can try UI Automator

Hello professionals, my problem is that my university does not allow me to use qualitative interview methods to investigate the usage context of a web form that I have to create.
It is a form where people should be able to order an individual song from a musician. There is already competition out there, but how can I get the usage context out of a competition analysis?
If you have any ideas, please let me know. It would be great if you could point me to some books which could contain an answer.

Answer
A think aloud protocol would be a better way to validate the usage scenario.

Many web applications or web sites offer the feature that when the user moves the mouse over a link, then additional information concerning the link is shown in a popup or overlay. A critical point in this feature is the length of the delay between mouse over event and displaying the popup. If it is to small, then it is likely that the popup with the additional info is displayed when the user just moved the mouse unintentionally over the link, which can be annoying. If it is to long, the user has to wait for the info which undermines the idea behind this construction. Are there any studies that show what the optimal length of such a delay is?
Relevant answer
Answer
As Dirk mentions above, optimal is dependent on the context of the overlay. If the overlay is unobtrusive, easily dismissed, and does not block further engagement (such as continuing to read within a paragraph of text), a short delay of 0.2 - 0.3 seconds will work just fine.
If the overlay is larger or more visually involved (text + images, etc.), consider an intermediate cue to the user- such as underlining the word with a 0.1 - 0.2 second fade, then fading the overlay in sometime between 0.4 and 0.6 seconds. This will assist in training the user to anticipate the overlay when they see the underline appear, give them immediate feedback that the hover means something, and allow them to avoid unanticipated UI changes.

In order to use a best model to evaluate the usability of web-based learning application
Relevant answer
Answer
Your question is not specific enough. What are you trying to prove? That one web based learning application is easier to use than another. This does not say that subjects are able to acquire more skills through an easier to use application as learnign depends on the content proposed by the application. 
While there are numerous ways to measure usability, once you have measured the usability of an application, what will you do with the results? I guess, you would recommend the use of an easier to use application. However, you need to ensure that the contents in the two applications, you are comparing, are the same to be able to make your recommendation. 
In one of my publications, I measured the usability of two versions of a web-based info retrieval application. In one version, some usability heuristics were implemented while in the second application, all web usability heuristics were implemented. Through usability trials, the study tried to identify if the extra efforts to implement all usability heuristics had a significant positive impact on usability. The study showed that it took less time to find the information in the second version. However, subjects committed more errors using the second version. Moreover, subjects had higher "Ease of use perceptions" for the first version. Finally, there was no significant statistical difference between the three measures (time, error EOU perceptions) between the two groups. This led to the conclusion that the extra efforts was not worthhwhile for an application developed without user participation and user task analysis.  
The above study shows that while usability experts will find the second version as easier to use due to the implementation of all user interface design heuristics, subjects undertaking a usability trial find the first version as easier to use. So which of the two applications should we recommend to users? To find out, as well as usability, other criteria should be measured.

Hyperlinks embedded within longer passages of continuous text may inhibit readability. See Obendorf and Weinreich. On the other hand one may think that embedded links give more context and therefore may increase navigability. Do you know about any more studies on embedded versus at-the-end lists of links?
Relevant answer
Answer
Rather than associating reading difficulty with the embedding of hyperlinks, your referenced paper
Comparing Link Marker Visualization Techniques - Changes in Reading Behaviour1
found the source of difficulty was the use of underlining as the highlighting mechanism and that the use of other forms of visual clues , e.g. the use of  translucent overlays, had advantages.
Other papers with related research are:
On Measuring the Impact of Hyperlinks on Reading2,  Fitzsimmons, et.al
which used used eye tracking measurements and concluded:
" ... that hyperlinked text [without underlining]  did not generally have a negative impact upon reading behaviour. However, participants did show a tendency to re-read sentences that contained hyperlinked uncommon (low frequency) words. This suggests that hyperlinks highlight important information to the reader and the hyperlinks add additional content which for more difficult concepts, invites rereading of the preceding text."
Effects of Visible and Invisible Hyperlinks on Vocabulary Acquisition and Reading Comprehension for High- and Average-Foreign Language Achievers3, Nikolova
confirming a previous study4
"... that visible links do not act as distractors for any of the groups represented in this study. Since, in addition, their impact on the average-achievers group was positive, our recommendation for people creating software would be to use marked [i.e. visible] links for annotated words"
 
The following study:
Hypermedia annotation presentation: the effect of location and type on the EFL learners’ achievement in reading comprehension and vocabulary
acquisition5by AbuSeileek
has the information you seek concerning embedded versus other locations:
"...The data suggest that reading passages with hypermedia annotations significantly benefits passage comprehension and vocabulary (compared to reading passages with no annotations). The best performance was observed in the condition where glosses were placed [immediately] after the glossed word"
 
hope this helps

How do we differentiate between Information Architecture and Taxonomy? Many have a view that both are one and the same whereas personally I feel that IA is how users want to see infomation whereas taxonomy is arranging the content as per information hierarchy as per business needs.
Relevant answer
Answer
Taxonomy is about actually doing the work.. describing, classifying and making systematic sense of the relationships between taxa.
Information architecture is about the way you organise and disseminate the results.
Thw two are to my mind completely different
