Aquest projecte és l’exemplificació del punt on la teoria i la pràctica s’uneixen. Mostra com la tasca socioeducativa que es duu a terme a un recurs on es dóna atenció residencial a joves (majors d’edat) amb una mesura judicial de règim obert, pot encaixar perfectament amb el que teoria de la resiliència argumenta. S’utilitza el model resilient de la casita el qual es fa servir de cinc possibles àrees d’intervenció. Es tracta d’un estudi on es justifiquen les raons de per què el Pis de Joves d’Emancipació pot ser definit com una Institució Resilient

En l'estudi que es presenta a continuació, s'analitza l'estereotip de mestressa de casa a la publicitat televisiva actual. Per a això, s’examinen les anteriors dècades amb la finalitat de seguir l'evolució d'aquest estereotip fins a l'actualitat, donant interès en els spots corresponents al sector neteja de la llar. Com a resultat de l'anàlisi, es podrà conèixer si hi ha hagut canvis, i quin tipus de canvis s'han produït.

Not much has been said about the grammar of Iraqi Arabic. This research is an attempt to shed light on the nature of IA relative clauses. The research focuses on the behavior of the resumptive strategy as opposed to the gap strategy. We consider islandhood, Weak and Strong CrossOver, reconstruction and scope binding, in order to further understand the behavior of resumption. The final conclusion reached is that in Iraqi Arabic the resumptive strategy is actually related to the gap strategy in several respects; and in those where it differs we propose that gaps (traces) are replaced by trace+pronoun complex

Introducción Estudios en colecistectomías y cáncer colorrectal demostraron que la laparoscopia genera menor respuesta inflamatoria sistémica. Escasos trabajos en cáncer gástrico evalúan el impacto inflamatorio en laparoscopia y emplean metodología deficiente. Hipótesis Demostrar mediante el estudio de tejido peritoneal la menor respuesta inflamatoria(protein-arrays) en pacientes gastrectomizados por laparoscopia vs. vía abierta. Material y métodos 26 pacientes: laparoscópica (12) vs. abierta (14); 2010-2012. Resultados Basados en TNF muestran incremento similar de respuesta a la agresión quirúrgica (aunque hubo diferencias en valores finales en ambos abordajes). Conclusiones Resultados preliminares apuntan hacia conclusiones estadísticamente significativas que apoyen nuestra hipótesis: menor respuesta inflamatoria en laparoscopia y correlación con datos clínicos.

Se plantea un ensayo clínico a fin de determinar la utilidad de una matriz estructural biodegradable (ME, en trámite de licencia de patente) enriquecida con fibrina y/o plasma rico en plaquetas (PRP) para restitución de volumen y regeneración tisular. Consta de dos fases. La primera in vitro, donde se definen las características físicas y químicas de la matriz estructural. La segunda, in vivo, que consiste en el análisis de la matriz enriquecida implantada en el tejido subcutáneo abdominal de animales de experimentación, mediante pruebas de imágenes, histología y pruebas de biodistribución.

L´ecocardiografia per a estimar volums i funció ventricular dreta en malalts amb Tetralogia de Fallot (TF) està limitada per la importància del tracte de sortida de ventricle dret (TSVD).Objectiu: comparar diferents paràmetres ecocardiogràfics amb la RMN en malalts amb TF i IP severa. Resultats: L´excursió de l´anell tricuspidi i el valor de la ona S per Doppler tissular no es correlacionen amb la FE de VD calculada per RMN (FEVD). L´àrea fraccional a l´eix curt mostra una tendència no significativa (p=0,07) a correlacionarse amb la FEVD. Conclusions: els paràmetres ecocardiogràfics que inclouen el TSVD mostren una tendència a correlacionarse amb la FEVD, al contrari dels paràmetres de l´anell tricuspidi.

As stated in Aitchison (1986), a proper study of relative variation in a compositional data set should be based on logratios, and dealing with logratios excludes dealing with zeros. Nevertheless, it is clear that zero observations might be present in real data sets, either because the corresponding part is completelyabsent –essential zeros– or because it is below detection limit –rounded zeros. Because the second kind of zeros is usually understood as “a trace too small to measure”, it seems reasonable to replace them by a suitable small value, and this has been the traditional approach. As stated, e.g. by Tauber (1999) and byMartín-Fernández, Barceló-Vidal, and Pawlowsky-Glahn (2000), the principal problem in compositional data analysis is related to rounded zeros. One should be careful to use a replacement strategy that does not seriously distort the general structure of the data. In particular, the covariance structure of the involvedparts –and thus the metric properties– should be preserved, as otherwise further analysis on subpopulations could be misleading. Following this point of view, a non-parametric imputation method isintroduced in Martín-Fernández, Barceló-Vidal, and Pawlowsky-Glahn (2000). This method is analyzed in depth by Martín-Fernández, Barceló-Vidal, and Pawlowsky-Glahn (2003) where it is shown that thetheoretical drawbacks of the additive zero replacement method proposed in Aitchison (1986) can be overcome using a new multiplicative approach on the non-zero parts of a composition. The new approachhas reasonable properties from a compositional point of view. In particular, it is “natural” in the sense thatit recovers the “true” composition if replacement values are identical to the missing values, and it is coherent with the basic operations on the simplex. This coherence implies that the covariance structure of subcompositions with no zeros is preserved. As a generalization of the multiplicative replacement, in thesame paper a substitution method for missing values on compositional data sets is introduced

All of the imputation techniques usually applied for replacing values below thedetection limit in compositional data sets have adverse effects on the variability. In thiswork we propose a modification of the EM algorithm that is applied using the additivelog-ratio transformation. This new strategy is applied to a compositional data set and theresults are compared with the usual imputation techniques

The main objective of this ex post facto study is to compare the differencesin cognitive functions and their relation to schizotypal personality traits between agroup of unaffected parents of schizophrenic patients and a control group. A total of 52unaffected biological parents of schizophrenic patients and 52 unaffected parents ofunaffected subjects were assessed in measures of attention (Continuous PerformanceTest- Identical Pairs Version, CPT-IP), memory and verbal learning (California VerbalLearning Test, CVLT) as well as schizotypal personality traits (Oxford-Liverpool Inventoryof Feelings and Experiences, O-LIFE). The parents of the patients with schizophreniadiffer from the parents of the control group in omission errors on the ContinuousPerformance Test- Identical Pairs, on a measure of recall and on two contrast measuresof the California Verbal Learning Test. The associations between neuropsychologicalvariables and schizotpyal traits are of a low magnitude. There is no defined pattern ofthe relationship between cognitive measures and schizotypal traits

In the eighties, John Aitchison (1986) developed a new methodological approach for the statistical analysis of compositional data. This new methodology was implemented in Basic routines grouped under the name CODA and later NEWCODA inMatlab (Aitchison, 1997). After that, several other authors have published extensions to this methodology: Marín-Fernández and others (2000), Barceló-Vidal and others (2001), Pawlowsky-Glahn and Egozcue (2001, 2002) and Egozcue and others (2003).

Hungary lies entirely within the Carpatho-Pannonian Region (CPR), a dominant tectonic unit of eastern Central Europe. The CPR consists of the Pannonian Basin system, and the arc of the Carpathian Mountains surrounding the lowlands in the north, east, and southeast. In the west, the CPR is bounded by the Eastern Alps, whereas in the south, by the Dinaridic belt. (...)

The application of Discriminant function analysis (DFA) is not a new idea in the studyof tephrochrology. In this paper, DFA is applied to compositional datasets of twodifferent types of tephras from Mountain Ruapehu in New Zealand and MountainRainier in USA. The canonical variables from the analysis are further investigated witha statistical methodology of change-point problems in order to gain a betterunderstanding of the change in compositional pattern over time. Finally, a special caseof segmented regression has been proposed to model both the time of change and thechange in pattern. This model can be used to estimate the age for the unknown tephrasusing Bayesian statistical calibration
