Die Analyse von Netzwerken hat in der Soziologie seit dem 20. Jahrhundert einen hohen Stellenwert, ist aber auch für andere Disziplinen interessant. Zum Beispiel bei der Untersuchung von neuronale Netzen oder DNA-Transkriptionen in der Biologie. Für die Evaluation von Mustern gibt es verschiedene Methoden, wobei wir in dieser Arbeit den Fokus auf den statistischen Vergleich des realen Netzwerks...

The National Tuberculosis Advisory Committee (NTAC) was established in 1999 as a subcommittee of Communicable Diseases Network Australia (CDNA). The terms of reference of NTAC are: • to provide strategic, expert advice to CDNA on a coordinated national and international approach to Tuberculosis (TB) control; and • to develop and review nationally agreed strategic and implementation plans for th...

The coordination problem of relief items’ distribution operations is essential in humanitarian relief chains. If the coordination is proper, it will improve the response phase to the crisis. In order to improve the coordination in humanitarian relief chains, distribution and warehousing operations of relief items were outsourced to the third-party logistics. In this paper, the procurement-distr...

J. Hertz Nordita Blegdamsvej 17 2100 Copenhagen 0 Denmark The problem of learning from examples in multilayer networks is studied within the framework of statistical mechanics. Using the replica formalism we calculate the average generalization error of a fully connected committee machine in the limit of a large number of hidden units. If the number of training examples is proportional to the n...

DNA samples collected in clinical trials and stored for future research are valuable to pharmaceutical drug development. Given the perceived higher risk associated with genetic research, industry has implemented complex coding methods for DNA. Following years of experience with these methods and with addressing questions from institutional review boards (IRBs), ethics committees (ECs) and healt...

Conventional wisdom suggests that CEO membership of the compensation committee is an open invitation to rent extraction by self-serving executives. However, using data from New Zealand – where CEO compensation committee membership is relatively common – we find that annual pay increments for CEOs with this apparent advantage averaged six percentage points less than those enjoyed by other CEOs d...

This symposium provided a useful forum for the discussion of issues relating to the design and conduct of clinical trials. There is a need for greater awareness of the complexity of modern day trials, in which a host of statistical, logistical, regulatory and ethical issues are involved. Issues discussed ranged from the effect of sample size on the outcome, and subgroup analysis, to defining an...
