    Abstract
    Social networks evolve over time with the addition and removal of nodes and links to survive and thrive in their environments. Previous studies have shown that the link-formation process in such networks is influenced by a set of facilitators. However, there have been few empirical evaluations to determine the important facilitators. In a research partnership with law enforcement agencies, we used dynamic social-network analysis methods to examine several plausible facilitators of co-offending relationships in a large-scale narcotics network consisting of individuals and vehicles. Multivariate Cox regression and a two-proportion z-test on cyclic and focal closures of the network showed that mutual acquaintance and vehicle affiliations were significant facilitators for the network under study. We also found that homophily with respect to age, race, and gender were not good predictors of future link formation in these networks. Moreover, we examined the social causes and policy implications for the significance and insignificance of various facilitators including common jails on future co-offending. These findings provide important insights into the link-formation processes and the resilience of social networks. In addition, they can be used to aid in the prediction of future links. The methods described can also help in understanding the driving forces behind the formation and evolution of social networks facilitated by mobile and Web technologies.

    Content
    Ablieferung als PDF oder Zip-Archiv Geschehen soll die Ablieferung am liebsten in PDF-Form, über ein Webformular. Bei Bedarf, nämlich "wenn Ihre Netzpublikation aus mehreren Dateien besteht, z. B. einer oder mehreren HTML-Seiten mit Bildern", darf man sie auch auch als Zip-Archiv abgeben. Wie es sich mit privaten Webseiten genau verhält, ist derzeit nicht ganz klar. "Lediglich privaten Zwecken dienende Websites" sind beispielsweise freigestellt - aber was genau ist im Netz lediglich privat? Ein Blog? Auch, wenn darin das Weltgeschehen oder die deutsche Politik kommentiert wird? Auch dann, wenn neben den Blog-Einträgen Google-Anzeigen erscheinen? Da es sich um eine Pflichtabgabe handelt, ist sie, zumindest theoretisch, auch strafbewehrt. Nach einer Abmahnung kann es heise.de zufolge bis zu 10.000 Euro Strafe kosten, wenn man seine Netz-Inhalte nicht bei der DNB abliefert. Eine Erklärseite der DNB schränkt allerdings ein: "Die Entwicklung geeigneter Verfahren für den Massenbetrieb der Sammlung, Erschließung und Archivierung von Netzpublikationen erfolgt stufenweise." Im Klartext: Man weiß bei der DNB selbst noch nicht so genau, wie das alles funktionieren und organisiert werden soll. So lange das nicht abschließend geklärt ist, wird die Bibliothek "keine Ordnungswidrigkeitsverfahren anstrengen". Außerdem werde man "abzuliefernde Netzpublikationen gegebenenfalls nicht gleich übernehmen, sondern vormerken und erst anfordern, wenn der Stand der Technik und der Absprachen dies zulässt." Zudem hat die Bibliothek das Recht, von der Übernahme von Inhalten abzusehen, unter anderem dann, wenn "technische Verfahren die Sammlung und Archivierung nicht oder nur mit beträchtlichem Aufwand erlauben". Bleibt abzuwarten, wie weit die Nationalbibliothek diese Ausnahmen ausdehnen wird - sonst kommt ein Speicherplatzbedarf auf die Einrichtung zu, der den Steuerzahler beträchtliche Summen kosten dürfte."

    Abstract
    Über Klickbetrug Internetwerbung wird immer wichtiger. Wie in jeder Wachstumsbranche versuchen auch hier Kriminelle von diesem Wachstum zu profitieren. Dies ist durch die Manipulation von Pay-Per-Click (PPC) Werbeanzeigen mithilfe künstlich produzierter Klicks möglich - eine Vorgehensweise, die als Klickbetrug (Click Fraud) bekannt ist. Klickbetrug ist nicht schwierig und könnte daher die Existenz von Firmen wie Google bedrohen. Zur Zeit scheint es keine Möglichkeit zu geben, Klickbetrug zu entdecken oder zu verhindern. Man kann Klickbetrug jedoch vermeiden, indem man PPC Werbung durch eine andere Berechnungsgrundlage, wie z. B. Cost-Per-Action, ersetzt.
