Book review: visual insights: a practical guide to making sense of data by Katy Börner and David E. Polley
This book, developed for use in an information visualisation MOOC, covers data analysis algorithms that enable extraction of patterns and trends in data, with chapters devoted to âwhenâ (temporal data), âwhereâ (geospatial data), âwhatâ (topical data), and âwith whomâ (networks and trees); and to systems that drive research and development. Jamie Cross finds that the bookâs hands-on sections demand time and effort, and more reflection on how we exist in and relate to the world would have been welcome
Anthropology for sale
This introduction to the Anthropology for Sale special issue makes a case for renewed attention to the selling and salescraft in anthropology. Rather than presume to know in advance what kinds of ethics and interests underpin the moment of sale the contributors to this Special Issue ask how sales work allows people to perform themselves as moral actors. In this introduction we situate the moment of sale as a moment of possibility charged with play, charisma, spin and seduction, reflect on the language and rhetoric of selling, consider the presence of kinship, gender, class, caste in the marketplace, and emphasise the precariousness of selling in contexts of global economic uncertainty

Essays on Economic and Policy Time Variations in Small Open Economies
This thesis consists of four research papers. The first three
papers explore the prevalence and significance of time variation
within the Australian economy. The final paper is distinct in
that it analyzes the effects of economic and policy uncertainty
on the Canadian economy.
In the first paper (Chapter 2), I address recent concerns that
Australian monetary policy is currently less effective than in
the past. To investigate this hypothesis, I estimate a time
varying structural vector autoregression (SVAR) model. The main
result is that monetary policy effectiveness has increased over
the sample period, with little evidence to support the claim of a
weaker transmission mechanism since the 2007/08 global financial
crisis.
In the second paper (Chapter 3 â joint with Aubrey Poon), we
build on the results in the first paper by investigating the
forecasting properties of Gaussian and Student's-t distributed
classes of time varying autoregressive models when predicting
Australian macroeconomic variables. The main result is that time
varying parameters, stochastic volatility and the Student's-t
error distribution are all important modeling features of the
data. More specifically, a VAR model with the proposed features
provides the best inflation and interest rate forecasts over the
entire sample. Surprisingly, a simple rolling window
autoregressive model provides the best real GDP growth
forecasts.
In the third paper (Chapter 4 â joint with Aubrey Poon), we
build on the results in the first two papers, by quantifying the
impacts of international shocks in driving Australian business
cycle fluctuations. Our methodology builds on classes of Gaussian
and Student's-t distributed, time varying panel VAR models, by
proposing a fat-tailed common stochastic volatility factor. We
find an important asymmetry in the effects of international
shocks, with around 47 percent of negative and 68 percent of
positive fluctuations resulting from foreign disturbances. More
generally, international shocks have contributed to around half
of all Australian business cycle fluctuations over the past two
decades.
The fourth paper (Chapter 5 â joint with Aubrey Poon, Joshua
Chan and Timothy Kam), deviates from the first three papers in
that it uses Canadian data. Our objective is to quantify the
impacts of uncertainty shocks to the business cycle fluctuations
of a small open economy. Using a Bayesian-estimated structural
model, we quantify which time-varying risk â in domestic demand
or supply conditions, in domestic monetary or fiscal policy, or,
in international economic and policy spillovers factors â
matter for a small open economy like Canada. Our results suggest
that the historical movements in Canadian real GDP are due
largely to domestic fiscal- and monetary-policy shocks, and, due
to non-negligible time variations in the riskiness of these
policy shocks
