Persuading young consumers to make healthy nutritional decisions.
There is widespread concern that consumers are making inappropriate decisions about what they eat, leading to a growing incidence of obesity and chronic illness which will strain public health budgets and damage economic competitiveness. Inappropriate nutritional decisions and obesity are of particular public policy importance where young consumers are concerned. The paper investigates how consumers, particularly young consumers, can be persuaded to make better nutritional decisions voluntarily, and how government and commercial persuasive communications can be deployed to facilitate such decisions. The key conclusions are that the mass media are not a reliable vehicle for bringing about the desired behavioural changes, but that new media, such as the Internet and âtext messagingâ should be used to deliver tailored messages to individuals, particularly younger consumers

Dilaton-Axion hair for slowly rotating Kerr black holes
Campbell et al. demonstrated the existence of axion ``hair'' for Kerr black
holes due to the non-trivial Lorentz Chern-Simons term and calculated it
explicitly for the case of slow rotation. Here we consider the dilaton coupling
to the axion field strength, consistent with low energy string theory and
calculate the dilaton ``hair'' arising from this specific axion source.Comment: 13 pages + 1 fi

Network Inference via the Time-Varying Graphical Lasso
Many important problems can be modeled as a system of interconnected
entities, where each entity is recording time-dependent observations or
measurements. In order to spot trends, detect anomalies, and interpret the
temporal dynamics of such data, it is essential to understand the relationships
between the different entities and how these relationships evolve over time. In
this paper, we introduce the time-varying graphical lasso (TVGL), a method of
inferring time-varying networks from raw time series data. We cast the problem
in terms of estimating a sparse time-varying inverse covariance matrix, which
reveals a dynamic network of interdependencies between the entities. Since
dynamic network inference is a computationally expensive task, we derive a
scalable message-passing algorithm based on the Alternating Direction Method of
Multipliers (ADMM) to solve this problem in an efficient way. We also discuss
several extensions, including a streaming algorithm to update the model and
incorporate new observations in real time. Finally, we evaluate our TVGL
algorithm on both real and synthetic datasets, obtaining interpretable results
and outperforming state-of-the-art baselines in terms of both accuracy and
scalability
