This collection examines the continuities and changes that have set
the Dominican political system apart from its Latin American
counterparts over the last couple of decades. Whereas traditional
political parties have lost support throughout Latin America, and
electoral systems have devolved into illiberal democracies,
Dominican democracy remains flawed but vibrant with a popular
embrace of party politics. Across eight chapters a collection of
subject experts argue that the Dominican case offers valuable
lessons to understand that even though traditional political
parties are endangered throughout the region, they are not going
anywhere. The book analyzes topics including electoral politics,
the quality of Dominican democracy, political parties, corruption,
relations with Haiti and the United States, migration, the
Dominican diaspora, gender and politics, social movements, and
civil participation and citizenship, to reveal how the Dominican
case proves that traditional political parties can adapt in order
to survive, turning themselves into major sources of patronage,
appealing to personalistic politics, and tinkering with the
constitution in order to stay relevant. Dominican Politics in the
Twenty First Century will be a vital resource for understanding
contemporary Dominican politics. It will appeal to political
scientists, Latin Americanists, and students of democracy,
comparative politics, and electoral politics in general.
This thesis sheds valuable new light on the second-order
cosmological perturbation theory, extensively discussing it in the
context of cosmic microwave background (CMB) fluctuations. It
explores the observational consequences of the second-order vector
mode, and addresses magnetic field generation and the weak lensing
signatures, which are key phenomena of the vector mode. The author
demonstrates that the second-order vector mode, which never appears
at the linear-order level, naturally arises from the non-linear
coupling of the first-order scalar modes. This leads to the
remarkable statement that the vector-order mode clearly contributes
to the generation of cosmological magnetic fields. Moreover, the
weak lensing observations are shown to be accessible to the vector
mode. On the basis of ongoing and forthcoming observations, the
thesis concludes that the second-order vector mode is detectable.

Vision-based control of wheeled mobile robots is an interesting
field of research from a scientific and even social point of view
due to its potential applicability. This book presents a formal
treatment of some aspects of control theory applied to the problem
of vision-based pose regulation of wheeled mobile robots. In this
problem, the robot has to reach a desired position and orientation,
which are specified by a target image. It is faced in such a way
that vision and control are unified to achieve stability of the
closed loop, a large region of convergence, without local minima
and good robustness against parametric uncertainty. Three different
control schemes that rely on monocular vision as unique sensor are
presented and evaluated experimentally. A common benefit of these
approaches is that they are valid for imaging systems obeying
approximately a central projection model, e.g., conventional
cameras, catadioptric systems and some fisheye cameras. Thus, the
presented control schemes are generic approaches. A minimum set of
visual measurements, integrated in adequate task functions, are
taken from a geometric constraint imposed between corresponding
image features. Particularly, the epipolar geometry and the
trifocal tensor are exploited since they can be used for generic
scenes. A detailed experimental evaluation is presented for each
control scheme.
