title: The New Zealand performance based research fund and its impact on publication activity in economics

authors: Tressler, John

subjects: research measurement

abstract: New Zealand’s academic research assessment scheme, the Performance Based Research Fund (PBRF), was launched in 2002 with the stated objective of increasing research quality in the nation’s universities. Evaluation rounds were conducted in 2003, 2006 and 2012. In this paper, we employ 22 different journal weighting schemes to generate output estimates of refereed journal paper and page production over three six year periods (1994-1999; 2000-2005 and 2006-2011). These time periods reflect a pre-PBRF environment, a mixed assessment period, and a pure PBRF research environment, respectively. Our findings indicate that, on average, research productivity, defined in either paper or page terms, has increased since the introduction of the PBRF. However, this outcome is due to a major increase in the quantity of papers and pages produced per capita that has more than off-set a decline in the quality of published outputs since the introduction of the PBRF. In other words, our findings suggest that the PBRF has failed to achieve its stated goal of increasing average research quality, but it has resulted in substantial gains in productivity achieved via large increases in the quantity of refereed journal articles.

title: Validation of simulated real world TCP stacks

authors: Jansen, Samuel Thomas

subjects: computer science

abstract: The TCP models in ns-2 have been validated and are widely used in network research. They are however not aimed at producing results consistent with a TCP implementation, they are rather designed to be a general model for TCP congestion control. The Network Simulation Cradle makes real world TCP implementations available to ns-2: Linux, FreeBSD and OpenBSD can all be simulated as easily as using the original simplified models. These simulated TCP implementations can be validated by directly comparing packet traces from simulations to traces measured from a real network. We describe the Network Simulation Cradle, present packet trace comparison results showing the high degree of accuracy possible when simulating with real TCP implementations and briefly show how this is reflected in a simulation study of TCP throughput.
