title: Adversarial risk analysis for first-price sealed-bid auctions.

authors: Ejaz, Muhammad

subjects: adversarial risk analysis

abstract: Adversarial risk analysis (ARA) is an upcoming methodology that is considered to haveadvantages over the traditional decision-theoretic and game-theoretic approaches. ARAsolutions for ﬁrst-price sealed-bid (FPSB) auctions have been found but only under strongassumptions which make the model somewhat unrealistic. In this paper, we use ARAmethodology to model FPSB auctions using more realistic assumptions. We deﬁne a newutility function that considers bidders’ wealth, we assume a reserve price and ﬁnd solutionsnot only for risk-neutral but also for risk-averse as well as risk-seeking bidders. We modelthe problem using ARA for non-strategic play and level-k thinking solution concepts.

title: Reply to Chisholm (2011), Conservation status of New Zealand freshwater fish, 2009; Allibone et al.(2010)

authors: Allibone, Richard

subjects: New Zealand

abstract: Chisholm (2011) makes a number of statements regarding the longfin eel fishery and the monitoring of this fishery, and has questioned the threat ranking of this species by Allibone et al. (2010). Chisholm (2011) also notes that two reports were provided to the expert panel to consider as part of the threat ranking process.

title: Maori preservice primary teachers’ responses to mathematics investigations

authors: Hāwera, Ngārewa

subjects: mathematics

abstract: There has been concern for some years about the low mathematics achievement of Maori students in New Zealand. This case study reports on the responses of 18 Maori preservice teachers to investigative approaches to learning mathematics during their compulsory Year 1 mathematics education course, as a possible aid towards helping improve the achievement level of Maori in mathematics.
