AbstractThe radial density gradient (Gr) of Galactic cosmic rays in the ecliptic plane points outward from the Sun. This indicates an increasing density of cosmic ray particles beyond the Earth’s orbit. Due to this gradient and the direction of the Sun’s interplanetary magnetic field (IMF) above and below the IMF wavy neutral sheet, there exists an anisotropic flow of cosmic ray particles approximately perpendicular to the ecliptic plane (i.e. in the direction parallel to BIMF × Gr). This effect is called the north–south anisotropy (ξNS) and manifests as a diurnal variation in sidereal time in the particle intensity recorded by a cosmic ray detector. By analysing the yearly averaged sidereal diurnal variation recorded by five neutron monitors and six muon telescopes from 1957 to 1990, we have deduced probable values of the average rigidity spectrum and magnitude of ξNS. Furthermore, we have used determined yearly amplitudes of ξNS to infer the magnitude of Gr for particles with rigidities in excess of 10 GV.

<p>I have been involved in policing and crime prevention for many years. I was a sworn member of Victoria Police (Australia), a crime prevention coordinator in a New Zealand community, and am currently employed by New Zealand Police (NZP). My interest in international policing grew as I realised more and more police were serving in a number of roles overseas. At first, I thought this a nice departure from normal duties for those lucky enough to take up opportunities to contribute to policing in other countries. Deeper thought followed about the juxtaposition of western models of policing, international relations and the customs of developing countries. The more I tried to find out the more questions were raised. Soon it was evident that little had been written about international policing and even less about international policing in relation to the Pacific. The need for research that combines the study of cross-border policing of crime and criminality with international relations scholarship has been identified by Peter Andreas and Ethan Nadelmann in their 2006 co-authored book. A growing body of literature examines policing and development in the Pacific, but is mainly centred on conflicts in Melanesia with particular emphasis on the Regional Assistance Mission to Solomon Islands (RAMSI). Apparently, no single work discusses the needs of police services in the Pacific in relation to domestic policing and international cooperation. This work seeks to fill that gap.</p>
