Signal processing of microstructure profiles: integrating turbulent spatial scales in aquatic ecological modeling

The main objective of this thesis was the integration of microstructure information in synoptic descriptors of turbulence, that reflects the mixing processes. Turbulent patches are intermittent in space and time, but they represent the dominant process for mixing. In this work, the properties of turbulent patches were considered the potential input for integrating the physical microscale measurements. The development of a method for integrating the properties of the turbulent patches required solving three main questions: a) how can we detect the turbulent patches from he microstructure measurements?; b) which are the most relevant properties of the turbulent patches?; and ) once an interval of time has been selected, what kind of synoptic parameters could better reflect the occurrence and properties of the turbulent patches? The answers to these questions were the final specific objectives of this thesis.

Predicting Argentine ant invasion across spatial scales via ecological niche models

La formiga argentina (Linepithema humile) es troba entre les espècies més invasores: originària d'Amèrica del Sud, actualment ha envaït nombroses àrees arreu del món. Aquesta tesi doctoral intenta fer una primera anàlisi integrada i multiescalar de la distribució de la formiga argentina mitjançant l'ús de models de nínxol ecològic. D'acord amb els resultats obtinguts, es preveu que la formiga argentina assoleixi una distribució més àmplia que l'actual. Les prediccions obtingudes a partir dels models concorden amb la distribució actualment coneguda i, a més, indiquen àrees a prop de la costa i dels rius principals com a altament favorables per a l'espècie. Aquests resultats corroboren la idea que la formiga argentina no es troba actualment en equilibri amb el medi. D'altra banda, amb el canvi climàtic, s'espera que la distribució de la formiga argentina s'estengui cap a latituds més elevades en ambdós hemisferis, i sofreixi una retracció en els tròpics a escales globals.

An analysis of the Woodcock Reading Mastery Tests and the Diagnostic Reading Scales for use with hearing-impaired children

This paper examines two individually administered diagnostic reading tests, the Woodcock Reading Mastery Tests and the Diagnostic Reading Scales, to determine their value for use with hearing-impaired children.

A comparison of scores of deaf and hearing children on the Hiskey Test of learning ability and on performance scales

This paper discusses the Hiskey Test of learning ability and its use on hearing impaired and normal hearing children.

The utility of social behavior rating scales for children who are deaf and hard of hearing

This independent study provides an overview of the social-emotional and theory of mind development of children birth through high school and evaluates the utility of social-emotional rating scales in the classroom for children who are deaf and hard of hearing.

The implications for the EU and national budgets of the use of EU instruments for macro-financial stability. CEPS Special Report, 4 September 2012

The euro crisis has forced member states and the EU institutions to create a series of new instruments to safeguard macro-financial stability of the Union. This study describes the status of existing instruments, the role of the European Parliament and how the use of the instruments impinges on the EU budget also through their effects on national budgets. In addition, it presents a survey of other possible instruments that have been proposed in recent years (e.g. E-bonds and eurobonds), in order to provide an assessment of how EU macro-financial stability assistance could evolve in the future and what could be its impact on EU public finances.

The use of innovative financial instruments for financing EU policies and objectives: Implications for EU and national budgets. CEPS Special Report, October 2012

This CEPS Special Report analyses the proposed expansion of innovative financial instruments in the EU Multiannual Financial Framework for the 2014–20 period. It presents the economic rationale, governance principles and criteria that these instruments should follow and compares these with proposals from the European Commission. Based on this assessment, it makes recommendations for the proposed instruments.
