Dismissal protections in a global market: Lessons to be learned from Serco Ltd v Lawson

The rise of labour as a transnational phenomenon is an aspect of globalisation. New Zealand law relating to protection from dismissal without cause (unjustifiable dismissal) is failing employers and employees whose employment agreements have international elements. In New Zealand, protection from dismissal without cause is contained in the Employment Relations Act 2000 (ERA 2000) (NZ). However, the Act is not an ‘overriding statute’. Cases where the facts show the operation of global employment markets are decided according to conflict of laws rules relating to contracts. The operation of these rules can result in employees being inappropriately excluded from New Zealand dismissal protections. The complexity of the rules makes them inappropriate for the resolution of employment relationship problems, to the detriment of both employers and employees

Food storage, multiple equilibria and instability: Why stable markets may become unstable during food crises

A temporary-equilibrium model replicating institutional features of low-income agricultural economies is developed. In this model, food is held as an asset; because food production is relatively volatile, those with negative temporary income are net buyers of food. When food is the only asset, asset effects are likely to reduce the price-elasticity of the demand for food and can make it tatonnement-unstable, because the distributional effects of food price rises increase savings. When money is introduced, instability remains possible because a permanent rise in the price level increases risk, inducing substitution from money into food stocks.

More on Keynes and the Classics

This paper provides a simple, graphical review of the Keynes versus the classics debate. It focuses on four key issues: the roles of ¡ãexible wages and the velocity of money as well as the determination interest rates and the nominal price level. Its aim is to improve upon the rather bland presentation of Keynes' model usually found in textbooks and to give students a sense of the point counterpoint of this important debate.

VHF Boundary Layer Radar and RASS

This thesis describes the refinements, modifications and additions to a prototype Very High Frequency (VHF) Boundary Layer (BL) Spaced Antenna (SA) radar initially installed at the University of Adelaide's Buckland Park field site in 1997. Previous radar observations of the lowest few kilometres of the atmosphere, in particular the Atmospheric Boundary Layer, have used Ultra-High Frequency (UHF) radars. Unlike VHF radars, UHF radars are extremely sensitive to hydro-meteors and have difficulty in distinguishing clear-air echoes from precipitation returns. The advantages and requirements of using a VHF radar to observe the lowest heights is discussed in conjunction with some of the limitations. The successful operation of the system over long periods has enabled in-depth investigation of the performance of the system in a variety of conditions and locations. Observations were made from as low as 300m and as high as 8 km, dependent upon conditions. Comparisons between the radar and alternative wind measuring devices were carried out and examined. The antenna system of the radar is a critical component which was analysed in depth and subsequently re-designed. Through the use of numerical models and mea- surements, evaluation of different designs was accomplished. Further calibration of the remaining components of the full system has enabled estimations of the absolute received power. Additional parameters which can be derived with a calibrated radar were compared with values obtained by other authors, giving favourable results. Full Correlation Analysis (FCA) is the predominant technique used in this work. A brief discussion of the background theory and parameters which can be measured is described. A simple one-dimensional model was developed and combined with a 'radar backscatter model' to investigate potential sources of errors in the parameters determined using FCA with the VHF Boundary Layer Radar. In particular, underes- timations in the wind velocity were examined. The integration of a Radio Acoustic Sounding System (RASS) to obtain tempera- ture profiles is discussed. The theory of RASS measurements including the limitations and considerations which are required for the VHF BL radar are given. The difficulties encountered trying to implement such a system and the subsequent success using a Stratospheric Tropospheric (ST) Profiler in place of the BL radar is presented. Taken as a whole this thesis shows the success of the VHF BL to obtain mea- surements from as low as 300m. The validation of this prototype radar provides an alternative and, in certain situations, a superior device with which to study the lower troposphere.Thesis (Ph.D.)--University of Adelaide, Department of Physics and Mathematical Physics, 2001

Quantum Interference and Inelastic Scattering in a Model Which-Way Device

A which-way device is one which is designed to detect which of 2 paths is taken by a quantum particle, whether Schr\"odinger's cat is dead or alive. One possible such device is represented by an Aharonov-Bohm ring with a quantum dot on one branch. A charged cantilever or spring is brought close to the dot as a detector of the presence of an electron. The conventional view of such a device is that any change in the state of the cantilever implies a change in the electron state which will in turn destroy the interference effects. In this paper we show that it is in fact possible to change the state of the oscillator while preserving the quantum interference phenomenon.Comment: 5 pages, 7 figures, Localisation 2002 Toky

Synergistic literacies: Fostering critical and technological literacies in teaching legal research methods at the University of Waikato

Nowadays, new law courses are not approved unless both the "needs analysis" is convincing and the "consumer demand" is certain. Needs and demands today are driven by new pressures for technological literacy accelerated by globalisation and the current revolution in information and communication technologies (ICTs). The popular logic is that new global "knowledge economies" need "knowledge workers" or "wired workers" to labour in the new e-markets for goods and services and to use the burgeoning number and high quality of electronic information databases now essential to legal research. Students are acutely aware of these developments as well as of the highly competitive nature of the contemporary labour market for law graduates. Consequently, students are demanding more "how to" research skills training. This article puts in context the reasons why, at the University of Waikato, we regard creating synergy between critical and technological literacy as essential for teaching and learning law-in-context research methods, and then describes the curriculum we designed for a legal research methods course in order to trial this approach. From the start we have been clear that the new course was not just to be a "how to" course, and that we would be concentrating on critical literacy as much as technological literacy. For us, critical literacy is fundamental because it relates to the way in which one analyses the world, a process described as "becoming aware of the underlying structure of conceptions".1 This awareness includes the politics in the architectures that constitute the Internet and the assembly of information accessible on it. We designed our curriculum for critical literacy around five types of analysis. Our shorthand for this is to call these "the five 'Cs'". Our five interrelated categories for analysis focus on: Change - in society, economy and culture Concepts - legal and sociological concepts and analytical frameworks Critique (and standpoint or perspective) Comparisons (and Contrasts) Contexts. We argue that, at a minimum, these are the conceptual tools necessary to critique and engage the operation of the law in the context of society, noting especially inequalities and injustices. Throughout the course students are encouraged to harness technological literacy to each dimension of their analysis. This article consists of two main parts. The first part ("Context and Assumptions") explores in some depth the reasons for the need to teach critical literacy alongside technological literacy. The second part ("The Legal Research Methods Course") describes our efforts to promote the synergy between critical and technological literacies in the context of a fourth year optional course, Legal Research Methods 2000, at the University of Waikato School of Law

Estimating the size of the cosmic-ray halo using particle distribution moments

Context: Particle transport in many astrophysical problems can be described either by the Fokker–Planck equation or by an equivalent system of stochastic differential equations. Aims: It is shown that the latter method can be applied to the problem of defining the size of the cosmic-ray galactic halo. Methods: Analytical expressions for the leading moments of the pitch-angle distribution of relativistic particles are determined. Particle scattering and escape are analyzed in terms of the moments. Results: In the case of an anisotropic distribution, the first moment leads to an expression for the halo size, identified with the particle escape from the region of strong scattering. Previous studies are generalized by analyzing the case of a strictly isotropic initial distribution. A new expression for the variance of the distribution is derived, which illustrates the anisotropization of the distribution. Conclusions: Stochastic calculus tools allow one to analyze physically motivated forms for the scattering rate, so that a detailed realistic model can be developed
