The Construction of a State Peace Policy and the Process of Conflict Resolution

The academic literature specialized on processes of conflict resolution has focused on how third party intervention and mediation can contribute to end violent conflict, however it has also ignored the potential role of the state in countries affected by internal war. This article calls for a better understanding of the state, not only as a source of contemporary conflict but as a potential advocate of conflict resolution processes. It suggests that it is necessary and possible to involve the state in more effective processes of conflict resolution through the implementation of a State Peace Policy. The central argument is that some of the critical elements that should guide the state action when confronting the destructive logic of war and violence can be effectively undertaken through a public policy focused on building peace. After suggesting a general definition of State Peace Policy and highlighting some of its main attributes, the article recognizes that this sort of policy can also orientate the unfinished process of state consolidation in Colombia and other countries affected by internal conflict. The role of the state in the process of conflict resolution is crucial; however there are some issues normally ignored within the policy-making process, they must be seriously taken into account in order to eliminate the underlying structures that perpetuate conflict and delay the consolidation of sustainable peace.-----La literatura académica especializada en procesos de resolución de conflictos se ha centrado en el estudio de cómo la intervención de terceras partes y la labor de mediación pueden contribuir a poner fin a los conflictos violentos, sin embargo, también ha ignorado el rol potencial del estado en aquellos países afectados por la guerra interna.

A Monte Carlo-Based Fiber Tracking Algorithm using Diffusion Tensor MRI

Diffusion tensor magnetic resonance imaging, which measures directional information of water diffusion in the brain, has emerged as a powerful tool for human brain studies. In this paper, we introduce a new Monte Carlo-based fiber tracking approach to estimate brain connectivity. One of the main characteristics of this approach is that all parameters of the algorithm are automatically determined at each point using the entropy of the eigenvalues of the diffusion tensor. Experimental results show the good performance of the proposed approach

VLSI architecture for motion estimation in underwater imaging

El treball desenvolupat en aquesta tesi aprofundeix i aporta solucions innovadores en el camp orientat a tractar el problema de la correspondència en imatges subaquàtiques. En aquests entorns, el que realment complica les tasques de processat és la falta de contorns ben definits per culpa d'imatges esborronades; un fet aquest que es deu fonamentalment a il·luminació deficient o a la manca d'uniformitat dels sistemes d'il·luminació artificials. Els objectius aconseguits en aquesta tesi es poden remarcar en dues grans direccions. Per millorar l'algorisme d'estimació de moviment es va proposar un nou mètode que introdueix paràmetres de textura per rebutjar falses correspondències entre parells d'imatges. Un seguit d'assaigs efectuats en imatges submarines reals han estat portats a terme per seleccionar les estratègies més adients. Amb la finalitat d'aconseguir resultats en temps real, es proposa una innovadora arquitectura VLSI per la implementació d'algunes parts de l'algorisme d'estimació de moviment amb alt cost computacional.

Validation of an automated algorithm for auditory brainstem response testing

This paper discusses the auditory brainstem response (ABR) testing for infants.

Evaluation of a feedback equalization algorithm in the CID Wearable Digital Hearing Aid

This paper describes the results of an investigation which examined the efficacy of a feedback equalization algorithm incorporated into the Central Institute for the Deaf Wearable Digital Hearing Aid. The study examined whether the feedback equalization would allow for greater usable gains when subjects listened to soft speech signals, and if so, whether or not this would improve speech intelligibility.

Cross-modality temporal resolution for auditory, vibrotactile, and visual stimuli

This paper reviews a study of cross-modalities and within-modalities and their effects on speech perception.

A European Deposit Insurance and Resolution Fund - An Update. CEPS Policy Brief No. 283, 11 September 2012

Cross-border banking is currently not stable in Europe. Cross-border banks need a European safety net. Moreover, a truly integrated European level banking system may help to break the diabolical loop between the solvency of the domestic banking system and the fiscal standing of the national sovereign. This policy paper first sketches the building blocks of a banking union. Importantly, a new European Deposit Insurance and Resolution Authority (EDIRA) should start simultaneously with the ECB assuming supervisory powers. A combination of European supervision and local resolution cannot work because it is not ‘incentive compatible’. Next, this paper proposes a transition period to gradually phase in the European deposit insurance coverage. Finally, we calculate that a European Deposit Insurance Fund would amount to about €30-50 billion for the 75 euro area banks that were subject to the EBA stress tests. This Fund could be created over a period of time through risk-based deposit insurance premiums levied on these banks. Once up and running, the Fund would then turn into a European Deposit Insurance and Resolution Fund to also deal with the resolution of one or more of these European banks.

The EU's External Action towards the Middle East: Resolution required. CEPS Commentary, 7 January 2012

Among the many foreign policy challenges the EU will have to address this year, such as cultivating workable ties with Ukraine, Russia and other neighbours in the east, reviving the transatlantic partnership in trade, rebalancing alliances with Asian countries, and pooling and sharing defence capabilities, the number one challenge that will take up most of the Foreign Affairs Council’s time is the Middle East. After months of half-baked unilateral attempts at resolving the foreign policy challenges posed by this troubled region, the moment has now come for the EU to take bold and concrete action, argues CEPS Senior Fellow Steven Blockmans in this new Commentary.

The diabatic contour advective semi-Lagrangian model

This article describes a novel algorithmic development extending the contour advective semi-Lagrangian model to include nonconservative effects. The Lagrangian contour representation of finescale tracer fields, such as potential vorticity, allows for conservative, nondiffusive treatment of sharp gradients allowing very high numerical Reynolds numbers. It has been widely employed in accurate geostrophic turbulence and tracer advection simulations. In the present, diabatic version of the model the constraint of conservative dynamics is overcome by including a parallel Eulerian field that absorbs the nonconservative ( diabatic) tendencies. The diabatic buildup in this Eulerian field is limited through regular, controlled transfers of this field to the contour representation. This transfer is done with a fast newly developed contouring algorithm. This model has been implemented for several idealized geometries. In this paper a single-layer doubly periodic geometry is used to demonstrate the validity of the model. The present model converges faster than the analogous semi-Lagrangian models at increased resolutions. At the same nominal spatial resolution the new model is 40 times faster than the analogous semi-Lagrangian model. Results of an orographically forced idealized storm track show nontrivial dependency of storm-track statistics on resolution and on the numerical model employed. If this result is more generally applicable, this may have important consequences for future high-resolution climate modeling.

Adaptive constraints for feature tracking

In this paper extensions to an existing tracking algorithm are described. These extensions implement adaptive tracking constraints in the form of regional upper-bound displacements and an adaptive track smoothness constraint. Together, these constraints make the tracking algorithm more flexible than the original algorithm (which used fixed tracking parameters) and provide greater confidence in the tracking results. The result of applying the new algorithm to high-resolution ECMWF reanalysis data is shown as an example of its effectiveness.
