title: Spatio-temporal modelling of crime using low discrepancy sequences

authors: Brown, Paul T.

abstract: We perform spatio-temporal modelling of burglary data in order to predict areas of high criminal risk for local authorities. We wish to account for several spatio-temporal factors as latent processes to make the model as realistic as possible, thus creating a model with a large latent eld with several hyperparameters. Analysis of the model is done using Integrated Nested Laplace Approximations (INLA) (Rue et al. 2009), a fast Bayesian inference methodology that provides more computationally efficient estimations than Markov Chain Monte Carlo (MCMC) methods.

title: The efficacy of principle-based corporate governance practices and firm financial performance: An empirical investigation

authors: Reddy, Krishna

subjects: boards of directors

abstract: Purpose – This paper seeks to address the effect that principle-based corporate governance practices have on the financial performance of large publicly-listed companies. In 2004, the New Zealand Securities Commission (NZSC) promulgated nine high level principles and guidelines for all business entities with an aim of improving corporate governance practices and boosting investor confidence in the New Zealand capital market. This event provides a point for empirically testing companies' responses. 
Design/methodology/approach – Panel data for the NZX top 50 companies over the period 1999-2007 are analysed using ordinary least squares (OLS) and two stage least squares (2SLS) regression techniques to evaluate whether: those firms that were continuously compliant with the NZSC requirements perform better; and the firm performance post-NZSC recommendations is better than pre-NZSC recommendations. Tobin's Q, market-to-book (MB) and return on assets (ROA) metrics are used as dependent variables.. 
Findings – The findings indicate that large listed companies have universally adopted the Securities Commission recommendations, establishing subcommittees for audit and remuneration, and having a majority of non-executive/independent directors on the board which, on average, have seven members. There is support for the view that the NZSC recommendations have had positive influence on firm performance measured by Tobin's Q, MB and ROA. The results show that the presence of a remuneration committee has had a positive influence on firm performance. 
Research limitations/implications – This study provides empirical support for the corporate governance recommendations made by the NZSC in 2004, giving support to the principle-based corporate governance practices to be adopted in New Zealand. The sequential testing of each NZSC recommendation provides a comprehensive picture of performance outcomes which has not been achieved in prior research. The interdependency issues are of interest and the correlation between recommendations provides useful insights. 
Originality/value – This study offers insights for policy makers interested in adopting principle-based corporate governance practices within their country. Within New Zealand, public policy developments and stock exchange listing requirements/regulatory issues with associated compliance burdens are better informed as a consequence of the research.

title: Secondary school subject choice: an ethnographic study

authors: Darnell, Doreen Anne

abstract: This study of subject choice followed two groups of pupils through the decision-making process at two state, co-educational high schools in the North Island of New Zealand. The high schools were similar in size, location, ethnic composition and range of home background of pupils, but had differing option systems. 
At the end of their form two year, 53 children (27 boys, 26 girls) were interviewed at their respective primary or intermediate schools while they were considering the options offered to them in form three at one of the two high schools. The children were re-interviewed the following year at their respective high schools. A further 37 pupils (17 boys, 20 girls) were interviewed in form four at their respective high schools while they were choosing fifth form subjects and were re-interviewed the following year after they had experienced the subjects they had chosen. All children in the study were chosen by their teachers as being representative of the range of pupils at their schools, in terms of ability, ethnic origin and home background. 
In addition, parents of eight of the younger children were interviewed in their homes and 31 teachers, representing all the subjects offered to the children at the two high schools, were interviewed at their respective schools. 
Analysis of interview transcripts showed that pupils’ decisions were influenced by the structure of the option systems, the attitudes of parents and peers and by the overt and covert actions of teachers. Access to information was found to be a key component of decision making. Children’s and parents’ views about the school subjects showed a strong measure of agreement, but there was less agreement between children’ views and teachers’ views. 
A model of decision making was elicited from the data and case studies illustrated the range of pupils’ individual experience, in particular, the experience of Maori pupils identified as ‘winners’ and ‘losers’ in the school system.
