Export-Oriented Policies, Women’s Work Burden and Human Development in Mauritius
This paper, looking at the case study of Mauritius, attempts to understand the factors affecting the relationship between EOP, women’s work burden along
different social backgrounds. The analysis is based on between-method triangulation consisting of a quantitative survey in the industrial sector and a qualitative survey in
the industrial and services sectors. The main result shows that women and the social reproductive process were not affected in the same way depending on the socioprofessional
background of the woman
Efficient estimation for a subclass of shape invariant models
In this paper, we observe a fixed number of unknown -periodic functions
differing from each other by both phases and amplitude. This semiparametric
model appears in literature under the name "shape invariant model." While the
common shape is unknown, we introduce an asymptotically efficient estimator of
the finite-dimensional parameter (phases and amplitude) using the profile
likelihood and the Fourier basis. Moreover, this estimation method leads to a
consistent and asymptotically linear estimator for the common shape.Comment: Published in at http://dx.doi.org/10.1214/07-AOS566 the Annals of

Radio mini-halos and AGN heating in cool core clusters of galaxies
The brightest cluster galaxy (BCG) in the majority of relaxed, cool core
galaxy clusters is radio loud, showing non-thermal radio jets and lobes ejected
by the central active galactic nucleus (AGN). Such relativistic plasma has been
unambiguously shown to interact with the surrounding thermal intra-cluster
medium (ICM) thanks to spectacular images where the lobe radio emission is
observed to fill the cavities in the X-ray-emitting gas. This `radio-mode AGN
feedback' phenomenon, which is thought to quench cooling flows, is widespread
and is critical to understand the physics of the inner regions of galaxy
clusters and the properties of the central BCG. At the same time,
mechanically-powerful AGN are likely to drive turbulence in the central ICM
which may contribute to gas heating and also play a role for the origin of
non-thermal emission on cluster-scales. Diffuse non-thermal emission has been
observed in a number of cool core clusters in the form of a radio mini-halo
surrounding the radio-loud BCG on scales comparable to that of the cooling
region. This contribution outlines the main points covered by the talk on these
topics. In particular, after summarizing the cooling flow regulation by AGN
heating and the non-thermal emission from cool core clusters, we present a
recent study of the largest collection of known mini-halo clusters (~ 20
objects) which investigated the scenario of a common origin of radio mini-halos
and gas heating. We further discuss the prospects offered by future radio
surveys with the Square Kilometre Array (SKA) for building large (>> 100
objects), unbiased mini-halo samples while probing at the same time the
presence of radio-AGN feedback in the host clusters.Comment: 8 pages, 3 figures. Conference proceeding of "The many facets of

Headaches
A 30 year old lady was seen by her family doctor during a busy clinic complaining of three episodes of left-sided headache over the previous four months. The pain was usually throbbing in nature and it increased slowly in intensity over about an hour. She usually would have to lie down in a dark room to obtain some relief. Nausea, vomiting and blurred vision usually accompanied the headache. She had had headaches in the past but usually less severe and relieved by two to four paracetamol tablets per day. She reported no family history of headaches and had not started any new medication. What would you do and what issues does this consultation raise?peer-reviewe
Congruence Veech Groups
We study Veech groups of covering surfaces of primitive translation surfaces.
Therefore we define congruence subgroups in Veech groups of primitive
translation surfaces using their action on the homology with entries in
. We introduce a congruence level definition and a
property of a primitive translation surface which we call property .
It guarantees that partition stabilising congruence subgroups of this level
occur as Veech group of a translation covering.
Each primitive surface with exactly one singular point has property
in every level. We additionally show that the surface glued from a regular
-gon with odd has property in level iff and are
coprime. For the primitive translation surface glued from two regular -gons,
where is an odd number, we introduce a generalised Wohlfahrt level of
subgroups in its Veech group. We determine the relationship between this
Wohlfahrt level and the congruence level of a congruence group
The Politics of Access: Examining Concerted State/Private Enforcement Solutions to Class Action Bans
Procedural and substantive constraints on the ability of ordinary people to access the civil justice system have become all too commonplace. The “justice gap” owes much to cuts in funding for legal aid and court administration, heightened pleading standards, ever-rising costs of discovery, increasingly restrictive views on standing to sue, and the co-opting of small claims court by businesses seeking to collect debts, among other obstacles in the path to the courthouse. But the most consequential impediment, surely, is the enforcement of mandatory arbitration clauses with class action bans, which bar consumers and employees from bringing or being represented in any form of collective litigation. This Article, written for a colloquium dedicated to the persistent problems of representation and access, explores the politics of regaining citizens’ rights to aggregate litigation in the wake of the Supreme Court’s broad endorsement of these class-ban provisions in AT&T Mobility LLC v. Concepcion. Given the political climate in Washington, D.C., it is a safe bet that federal legislation will not overrule Concepcion anytime soon. Meanwhile, state legislation constraining class-banning arbitration clauses faces the unremitting threat of FAA preemption. But scholars and access-to-justice advocates have begun to focus on a third avenue for overcoming claims—suppressing class action bans, referred to in this Article as “concerted state/private enforcement solutions.” Concerted state/private enforcement can take several forms—whether it’s state Attorneys General engaging private counsel to pursue parens patriae damages cases under the AG’s direction, utilizing a qui tam model, or creating a regime where government enforcers obtain liability verdicts that private parties can use as conclusive proof in individual arbitrations. Each holds its own promises and poses its own challenges. But unlike head-on state legislation, the concerted state/private options are all viable as a legal matter. The question of political viability, however, is more nuanced. This Article explores the unique political calculus for states confronting the implications of the various forms of state/private concerted enforcement activity as a way to restore their citizens’ access to justice in the post-Concepcion era
