title: Experiment databases: A new way to share, organize and learn from experiments

authors: Vanschoren, Joaquin

subjects: experimental methodology

abstract: Thousands of machine learning research papers contain extensive experimental comparisons. However, the details of those experiments are often lost after publication, making it impossible to reuse these experiments in further research, or reproduce them to verify the claims made. In this paper, we present a collaboration framework designed to easily share machine learning experiments with the community, and automatically organize them in public databases. This enables immediate reuse of experiments for subsequent, possibly much broader investigation and offers faster and more thorough analysis based on a large set of varied results. We describe how we designed such an experiment database, currently holding over 650,000 classification experiments, and demonstrate its use by answering a wide range of interesting research questions and by verifying a number of recent studies.

title: How cost-elastic are remittances? Estimates from Tongan migrants in New Zealand

authors: Gibson, John

subjects: Pacific islands

abstract: Pacific island economies are some of the most remittance dependent in the world. Proposals to lower the costs of sending money across borders are a core recommendation of recent international studies that aim to enhance the development impact of remittances. The potential increase in remittances that recipient countries can expect from such policies depends critically on the sensitivity of remittance transfers to the costs of remitting. This paper provides the first estimates of the cost elasticity of remittances, using data from a survey of Tongan migrants in New Zealand. The costs of remitting to Tonga are high by international standards and remittances are found to have a negative cost-elasticity with respect to the fixed fee component of money transfer costs. These findings suggest that Pacific island countries can expect a more than proportionate increase in remittances from a reduction in costs.

title: Māori & Psychology Research Unit Annual Report 2012

authors: Waitoki, Waikaremoana

abstract: Annual report of the Māori and Psychology Research Unit (MPRU) 2012. The unit was established in August of 1997. The unit is designed to provide a catalyst and support network for enhancing research concerning the psychological needs, aspirations, and priorities of Maori people. The MPRU is well situated to draw together skilled and experienced interdisciplinary research groups by networking and establishing working relationships with staff and students within the Faculty of Arts and Social Sciences, the University, and the wider community.
