Quotients of Strongly Proper Forcings and Guessing Models

We prove that a wide class of strongly proper forcing posets have quotients with strong properties. Specifically, we prove that quotients of forcing posets which have simple universal strongly generic conditions on a stationary set of models by certain nice regular suborders satisfy the $\omega_1$-approximation property. We prove that the existence of stationarily many $\omega_1$-guessing models in $P_{\omega_2}(H(\theta))$, for sufficiently large cardinals $\theta$, is consistent with the continuum being arbitrarily large, solving a problem of Viale and Weiss

Discrete-event simulation of process control in low volume high value industries

This paper presents a new method of process control for set-up dominant processes. This new method known as Set-up Process Algorithm (SUPA) was compared with existing industrial practices and statistical techniques in the literature. To test the method’s robustness, a generic discrete-event simulation model was built. This model was used to test four different statistical approaches to process control. It was concluded that SUPA offers a method of process control for set-up dominant processes, which is easier to apply than classically derived SPC approaches, by using simple rules and a traffic light system based on design specification. Simulation analysis shows that SUPA: is more sensitive, at detecting an incapable process as it will monitor more units when a process is less capable; is more sensitive than PRE-Control at detecting mean shifts in a process. SUPA is also a nonparametric methodology and therefore robust against processes with non-Gaussian distributions

Mutual Fund Expense Disclosures: A Behavioral Perspective

Mutual funds have enjoyed phenomenal growth with their numbers exceeding the number of public companies and their assets aggregating in excess of $9 trillion. Increasingly they are the investment instrument of choice by the proverbial widows, widowers and orphans, and a few school teachers are included as well. But how are best can that choice be one that is not only informed but informed in a way more likely to elicit a wise decision? This paper examines from a behavioral perspective how regulation can best disclose information related to two key factors for investors to compare competing mutual funds: fund returns and fund expenses. Our analysis reflects that the current disclosure process is deficient because it fails to reflect the insights of research on judgment and decision making, and particularly the need to distinguish between the availability of information and its processability by its user. The message of our article is straightforward: if regulators adhered to the insights provided by our paper, not only investors, but also the fund\u27s directors, would be greatly empowered so that better returns and lower costs could be expected

The Emergent Middle Classes in Timor-Leste and Melanesia: Conceptual Issues and Developmental Significance

The emergence of a middle class has been identified as an important factor driving economic and political transitions in Asia and Africa. Class has been 'happening' in the broader Pacific region1 for some time, as Gewertz and Errington (1999:2) observed of Papua New Guinea (PNG). Nevertheless, to date, little systematic policy attention has been given to questions of class. We believe that the concept of an emerging middle class provides a useful entry point for understanding significant developmental and political transformations in Timor-Leste and Melanesia and is important for informing development policies. However, in order to explore the potential consequences that an emergent middle class may have, it is necessary to first consider how such a class can be identified in the region. We have chosen to focus on Timor-Leste, PNG and Solomon Islands because these countries are undergoing comparable social and economic transitions, many of which correlate strongly with the emergence of a middle class. Such changes include rapid economic growth driven by resource booms in Timor-Leste and PNG, associated formalisation of regional economies, deepening urbanisation, increasing social integration with metropolitan powers through growing diaspora communities, changing consumption patterns, and the transformative impacts of social media following recent internet and mobile telephone penetration. This paper has three substantive sections. First, it considers contemporary discussions of class and development in Asia and other developing regions. Second, the paper develops a multidimensional framework for identifying an emergent middle class, drawing on a range of economic, political and social criteria. Finally, the paper uses these criteria to examine recent developments in each of three case study countries and then draws some conclusions on the developmental and political significance of an emergent middle class in the broader Pacific region with a view to establishing a longer term research agenda.AusAI
