The document discusses perception, cognition, and worldviews. It explains that when students learn, their brain changes by forming new neural connections and strengthening or eliminating existing connections. Learning occurs through enriched environments that provide novelty, engage multiple senses, and elicit high motivation and focused attention and significant emotional reactions. However, too much emotion can interfere with learning. It also notes that perception is variable, unreliable, and driven by both our senses and our mindsets. Worldviews provide basic assumptions about reality, values, cultural examples, and rules to guide behavior. Worldviews evolve gradually over time in response to changes in our environment and experiences.

The impact of p2p file distribution on paid content sales presentationAntonio Tresca
The document discusses research into the impact of piracy (and peer-to-peer file sharing) on paid content sales. It outlines the research approach, which includes analyzing prior work, addressing data quality, measuring results, assessing implications, and identifying next steps. Preliminary findings from analyzing O'Reilly Media and Thomas Nelson book sales data suggest piracy may help increase paid sales in some cases, though the sample sizes are small. Larger data sets and consideration of different viewpoints are needed to better understand piracy's complex effects.

The document summarizes the results of analyzing the quality of DNS and DNSSEC in the .se zone. Key findings include: signature lifetimes were found to be too short or long in some cases; most domains use adequate NSEC3 and RSA keys of appropriate lengths; and SOA expire values often lack connection to RRSIG expiration times which should be reviewed. Future work proposed includes frequent measurements to analyze trends over time and long term adherence to DNSSEC best practices recommendations.
OpenDNSSEC is a complete DNSSEC zone signer that automates the process of keeping track of DNSSEC keys and signing zones. It has three major components - the Key and Signing Policy (KASP) which defines how zones are signed, the Signer which does the automatic signing, and a hardware security module (HSM) or SoftHSM for key storage. Configuration involves setting up an HSM like SoftHSM, and XML configuration files for the KASP, zones to be signed, and per-zone signing parameters. The project aims to improve integration, documentation, testing and user experience to ready a 1.0 release.
The document discusses the DNS hierarchy and how it is structured. It begins with the root zone and lists the root name servers that host the root zone. It then shows some examples of top-level domains like .org and country-code TLDs like .se and the name servers that host them. Specific domains like iana.org and iis.se are given as examples and their authoritative name servers are listed. In total there are 168 root name servers.
1) In June 2005, all DNS name servers for the .SE domain will be ready to handle signed DNS zones to support DNSSEC.
2) In September 2005, the .SE domain zone will be signed for the first time, initially without including DNSSEC key fingerprints in the zone.
3) By mid-October 2005, DNSSEC key fingerprints will be added to the signed .SE zone and the keys will be published to validate the signature.
