I got into an interesting email discussion about social navigation with AOIR people on the email list.

Sony's latest Digital Rights Management (DRM)-endeavour earned a charge of “fraud, false advertising, trespass and the violation of state and federal statutes prohibiting malware, and unauthorized computer tampering”. The technology installs, unnoticed by the user, a piece of software that prevents consumers from unauthorised copying, is able to monitor and report user behaviour back to the firm and, accidentally, holds the door wide open for Trojans. Under other circumstances one would be tempted to describe such a strategy a hostile “spy at-tack”. In case of Sony BMG, this seems to be part of a business model to sell digital music to consumers. The talk will have a closer look at the charges of the EFF and a Californian lawyer against Sony BMG‚s latest DRM strategy. The Sony BMG case adds a number of interesting new dimensions to the ‘DRM and Consumer' debate. The talk will explain why the case is so important, also against the background of similar recent case law in Europe, and why it points into an entirely new direction of talking about DRM.
About the Speaker: Natali Helberger is Associate Professor at the Institute for Information Law, University of Amsterdam. Dr. Helberger is managing legal partner to the INDICARE project. INDICARE (Informed Dialogue about Consumer Acceptability of Rights Management Solutions in Europe) is a project co-funded by the European Commission. The objective of INDICARE is to address issues regarding consumer acceptability of digital rights management solutions; identify obstacles and suggest solutions. At the moment, she is a visiting scholar at the University of California, Berkeley.

I did some LaTeX learning and typesetting after I figured iWeb would not be good enough for the web site project. On the eMac I copied and pasted into TeXShop an old Open Office file made on my old Thinkpad and presently stored on my eMac. I then opened it using the local network between my machines in TeXShop on my Macbook. The file is a list of all the exercises and solutions I have done from the textbook for my introduction to probability course I studied in 1999. I created this file in 2003 to really learn probability and possibly help me repeat the course with better marks. As I have set the goal of having worked through and read the second chapter of two probability books by Sunday next weekend, I thought I should get working on this study as I have done nothing other than pull the books out of their shelves to date. After opening the file as a tex file I began to write proper LaTeX code for the content. I did figure out an elegant solution to equation numbering using the exercise numbering for the answers as equation numbering. I did not really do any solutions though I just converted what I had done in 2003 to laTeX.

- I read about the difference between chronic and acute schizophrenia and the misuse of these labels. I read that perhaps using the terms type 1 and type 2 is a better typology. Type 1 is where positive symptoms dominate and type 2 is where negative symptoms dominate instead of associating the label acute schizophrenia with positive symptoms and the label chronic schizophrenia with negative symptoms. This was in chapter 2 of this book,
- Howe, Gwen. Working With Schizophrenia: A Needs Based Approach (London, U.K. Jessica Kingsley, 1995).
- This chapter describes positive and negative symptoms of schizophrenia. Positive symptoms are symptoms added to the normal personality and negative symptoms meaning symptoms that take away from the normal personality. Normal here can simply mean what one was like before one's episode.
- The three basic types of positive symptoms are
- Altered Perceptions
- This is where hearing voices fits in and seeing things and also the distorted perceptions like weird faces and smells and tastes that are may be over sensitive to certain characteristics of the environment.
- Delusional Ideas
- This is where people feel they are being watched or are at the centre of attention. This can also constructed with ideas of reference. In my own experience this happens when one is tired after an abnormally long day. Thus this symptom could be connected with either stress or physical health. This symptom can also results in sexual confusion or lack of clearly defined sexual boundaries. Also here perceptions of illness and health can be distorted.
- Abnormal Thought Structure
- This is a symptom where ones thoughts jump all around or some detail like a license plate on a car in front can be meaningful when, in fact, there is really no real meaning to it. This can also result in having one's attention taken by an object where one appears to be staring into empty space or at a table or object on a table. This would be greater I believe if one was high on marijuana. This is also the symptom where the ideas of intrusive thoughts can effect someone. Also beliefs that one is a very bad person can effect someone with these symptoms when the person is actually not a bad person or has no intention of acting on these thoughts. This can be quite distressful and cause an anxiety in my experience.

- The bibliographic cite for this reading is
- Dieberger, Andreas. Social Connotation of Space in the Design for Virtual Communities and Social Navigation in Munro, Alan J. & Höök, Kristina. & Benyon, David. eds. Social Navigation of Information Space (London, UK: Springer, 1999) at 35-54.
- I am impressed with the understanding this author expresses about Usenet and its characteristics. Also this author is very aware of the privacy issues involved in the ideas of social navigation expressed so far in this book. Do we want others to know how we have used the web or say what we are buying at Amazon.com?
