Paths towards Consensus: Explaining Decision Making within the Swiss Global Justice Movement
We examine the conditions leading social movement organizations to adopt consensus in their internal decision making. To do so, we look at organizations of the Swiss global justice movement, which puts the search for consensus at center stage. Our findings show that the ways in which social movement organizations take decisions and their vision of democracy more generally are not...

The policies of unemployment protection in Europe
The abundant literature on welfare state policies, regimes or ‘worlds’ has been only limitedly interested in unemployment protection, and even less in youth unemployment protection. What is clearly lacking in the literature is an updated analysis of the most recent policies developed in European countries targeting youth. This mini-symposium aims to fill in this gap by presenting...

New challenges for the welfare state: The emergence of youth unemployment regimes in Europe?
In this article we discuss the emergence of ‘youth unemployment regimes’ in Europe, that is, a set of coherent measures and policies aimed at providing state responses to the problem of unemployment and, more specifically, youth unemployment. We classify these measures and policies along two main dimensions: unemployment regulations and labour market regulations. Using original data...

Patterns of change in youth unemployment regimes: France and Switzerland compared
The comparison between France and Switzerland enables us to compare a country that has a strong interventionist tradition in the labour market and whose youth unemployment is endemically high with a more liberal country that is faced with a more recent increase in youth unemployment but which, nevertheless, remains relatively measured. Starting from different rules and values, the...

Robustness in sample selection models
The problem of non-random sample selectivity often occurs in practice in many different fields. In presence of sample selection, the data appears in the sample according to some selection rule. In these cases, the standard tools designed for complete samples, e.g. ordinary least squares, produce biased results, and hence, methods correcting this bias are needed. In his seminal work,...

Two essays in statistics: a prediction divergence criterion for model selection & wavelet variance based estimation of latent time series models
This thesis is divided in two parts. First, it presents a new criterion for model selection which is shown to be particularly well suited in "sparse" settings which we believe to be common in many research fields. Our selection procedure is developed for linear regression models, smoothing splines, autoregressive and mixed linear models. These developments are then applied...

Robust VIF Regression with Application to Variable Selection in Large Datasets
The sophisticated and automated means of data collection used by an increasing number of institutions and companies leads to extremely large datasets. Subset selection in regression is essential when a huge number of covariates can potentially explain a response variable of interest. The recent statistical literature has seen an emergence of new selection methods that provide some...

Limits of the Allan Variance and Optimal Tuning of Wavelet Variance based Estimators
This article first demonstrates the inconsistency of the estimator based on the standard Allan Variance (AV) for composite stochastic processes. This result motivates the use of a recently developed estimator, called the Generalized Method of Wavelet Moments (GMWM) estimator. This estimator was previously shown to be consistent and asymptotically normally distributed under the...

N-acetylcysteine does not prevent contrast nephropathy in patients with renal impairment undergoing emergency CT: a randomized study
BACKGROUND: Patients admitted to the emergency room with renal impairment and undergoing a contrast computed tomography (CT) are at high risk of developing contrast nephropathy as emergency precludes sufficient hydration prior to contrast use. The value of an ultra-high dose of intravenous N-acetylcysteine in this setting is unknown. METHODS: From 2008 to 2010, we randomized 120...

An Algorithm for Automatic Inertial Sensors Calibration : Proceedings of the ION GNSS 2013
We present an algorithm for determining the nature of stochastic processes together with its parameters based on the analysis of time series of inertial errors. The algorithm is suitable mainly (but not only) for situations when several stochastic processes are superposed. In such cases, classical approaches based on the analysis of Allan variance or PSD are likely to fail due to the...

Robust Estimation of Bivariate Copulas
Copula functions are very convenient for modelling multivariate observations. Popular es- timation methods are the two-stage maximum likelihood and an alternative semi-parametric with empirical cumulative distribution functions (cdf) for the margins. Unfortunately, they can be hastily biased whenever relatively small model deviations occur at the marginal (empirical or parametric)...

Robust Estimation for Bivariate Distribution
Copula functions are very convenient for modelling multivariate observations. Popular estimation methods are the two-stage MLE and an alternative semi-parametric with empirical cdf for the margins. Unfortunately, they are hastily biased whenever relatively small model deviations occur at the marginal (empirical or parametric) and/or copula levels. In this master thesis we propose...

Wavelet-Variance-Based Estimation for Composite Stochastic Processes
This article presents a new estimationmethod for the parameters of a times series model.We consider here composite Gaussian processes that are the sum of independent Gaussian processes which, in turn, explain an important aspect of the time series, as is the case in engineering and natural sciences. The proposed estimation method offers an alternative to classical estimation based on...

Functional regulatory spaces
This article develops the concept of ‘‘Functional Regulatory Space'' (FRS) in order to analyze the new forms of State action addressing (super) wicked problems. A FRS simultaneously spans several policy sectors, institutional territories and levels of government. It suggests integrating previous policy theories that focused on ‘‘boundary-spanning regime,'' ‘‘...

Privacy, Democracy and Surveillance
How should we think about our claims to privacy and their relationship to security? Must we suppose that privacy should give way before the demands of security whenever the two cannot both be fully protected? This is the position presented by Sir David Omand on numerous occasions and, most recently, in his response to the revelations of Edward Snowden. However, this article shows,...
