A comparison of different ways of including baseline counts in negative binomial models for data from falls prevention trials
No full textA common design for a falls prevention trial is to assess falling at baseline, randomize participants into an intervention or control group, and ask them to record the number of falls they experience during a follow-up period of time. This paper addresses how best to include the baseline count in the analysis of the follow-up count of falls in Negative Binomial (NB) regression. We examine the performance of various approaches in simulated datasets where both counts are generated from a mixed Poisson distribution with shared random subject effect. Including the baseline count after log-transformation as a regressor in NB regression (NB-logged) or as an offset (NB-offset) resulted in greater power than including the untransformed baseline count (NB-unlogged). Cook and Wei's Conditional Negative Binomial (CNB) model replicates the underlying process generating the data. In our motivating dataset, a statistically significant intervention effect resulted from the NB-logged, NB-offset and CNB models, but not from NB-unlogged, and large, outlying baseline counts were overly influential in NB-unlogged but not in NB-logged. We conclude that there is little to lose by including the log-transformed baseline count in standard NB regression compared to CNB for moderate to larger sized datasets
Pseudo-Goodwin cycles in a Minsky model
No full text© The Author 2016. Published by Oxford University Press on behalf of the Cambridge Political Economy Society. All rights reserved. Goodwin cycles result from the dynamic interaction between a profit-led demand regime and a reserve army effect in income distribution. The paper proposes the concept of a pseudo-Goodwin cycle. We define this as a counter-clockwise movement in output and wage share space which is not generated by the usual Goodwin mechanism. In particular, it does not depend on a profit-led demand regime. As a demonstration, a simple Minsky model is extended by adding a reserve army distribution mechanism such that the wage share responds positively to output. In the extended Minsky model, cycles are generated purely through the interaction between financial fragility and demand. In a first step we assume no feedback from income distribution to demand. We demonstrate that the model generates a pseudo- Goodwin cycle in output-wage share space. In a second step, we show that the result continues to hold even if a wage-led demand regime is introduced, although this can introduce instability. Our models demonstrate that the existence of a counter- clockwise movement of output and the wage share cannot be regarded as proof of the existence of a Goodwin cycle and a profit-led demand regime

Ethics and ethnography – an experiential account
No full textIn this article, the authors discuss an ethical dilemma faced by the first author during the fieldwork of an ethnographic study of expertise in anesthesia. The example, written from the perspective of the first author, addresses a number of ethical issues commonly faced, namely, the researcher-researched relationship, anonymity and confidentiality, privacy, and exploitation. She deliberates on the influences that guided her decision and in doing so highlights some of the elements that combine to shape the data. The authors argue that this process of shaping the data is a symbiotic one in which the researcher and the community being studied construct the data together

God in Reverse: Art Architecture & Consciousness
No full textAuthored and illustrated by Goodwin (with both archival photographs and recent artwork), God in Reverse fuses biography, fiction, criticism, observation and imagination. It reveals a broad range of philosophies and cultural influences that underpin Goodwin's practice and elaborates on his unique and experimental world-view, as it applies to his architecture, public artworks, sculpture, drawings and performance art. Having studied architecture at both RMIT and UNSW, Goodwin has been a critical commentator of architecture and urbanism, particularly within Sydney, since the 1970s. The book moves seamlessly from lambasting the commercial greed of the Barangaroo wharf development, to ruminations on the divided city of Jerusalem, to lessons in urban planning offered by coral reefs. The ethical questions raised by the text span drone warfare and super-high density housing. Designed by award winning designer Sean Hogan, the book's taut and irreverent design is a testament to its unconventional content, with the text-flow and layout slowly discombobulating as the pages turn
