title: Integrability, Stäckel spaces, and rational potentials

authors: Kalnins, Ernie G.

subjects: Mathematics

abstract: For a variety of classical mechanical systems embeddable into flat space with Cartesian coordinates {xi} and for which the Hamilton–Jacobi equation can be solved via separation of variables in a particular curvalinear system {uj}, we answer the following question. When is the separable potential function v expressible as a polynomial (or as a rational function) in the defining coordinates {xi}? Many examples are given.

title: The merits of using citations to measure research output in economics departments: The New Zealand case

authors: Anderson, David L.

subjects: Citations

abstract: In this paper we explore the merits of utilizing citation counts to measure research output in economics in the context of a nation-wide research evaluation scheme. We selected one such system for study: the New Zealand government’s Programme-Based Research Fund (PBRF). Citations were collected for all refereed papers produced by New Zealand’s academic economists over the period 2000 to 2008 using the databases of the ISI/Web of Science and, to a limited extent, Google Scholar. These data allowed us to estimate the time lags in economics between publication of an article and the flow of citations; to demonstrate the impact of alternative definitions of ‘economics-relevant’ journals on citation counts; and to assess the impact of direct citation measures and alternative schemes on departmental and individual performance. Our findings suggest that the time-lags between publication and citing are such that it would be difficult to rely on citations counts to produce a meaningful measure of output in a PBRF-like research evaluation framework, especially one based explicitly on individual assessment.

title: Political critique and genealogical vision in te oriori a Rihi Puhiwahine, 1870s

authors: Iti Prendergast, Sam

abstract: Long before twentieth-century scholars developed the language to describe 'settler colonialism', nineteenth-century Māori writers, composers, and storytellers critiqued British imperialism and theorized colonial violence. In mōteatea, letters, and kōrero heke iho (narratives passed down), tūpuna Māori asked what British colonial settlement would mean for te ao Māori, the Māori world. As they reflected on the changes wrought by imperialism, tūpuna offered guidance for future uri (descendants). This is an article about the ways that one wahine Māori critiqued colonization and imagined Māori futures in the context of mid-nineteenth-century colonial invasion. More specifically, it is an article about how Rihi Puhiwahine, a renowned composer, guided her descendants through a world disfigured by British imperialism.
