Children At-Risk for Anxiety: Their Self-Esteem, Somatic Symptoms, and Perceptions of Parental Support

The present study examined children at risk for anxiety, analyzing their symptoms, self-esteem, and their perception of parental behavior. Data were collected as part of a large anxiety prevention study conducted at the University of Rhode Island. Elementary and middle school children who were identified as at risk for anxiety through an initial assessment were administered a battery of questionnaires, which included measures for anxiety, self-esteem, somatic symptoms, and perceptions of parental behavior. The primary hypothesis was that children at risk for anxiety would demonstrate low levels of self-esteem, especially if they concurrently displayed somatic symptoms and perceived their parental support as low. Moderating effects were not found in the current study, but there was a significant relationship between anxiety and self-esteem, across a broad range of anxiety symptoms and self-esteem domains. Perceived parental behavior was also related to anxiety. Specifically, higher parental control was related to higher anxiety. Perceived parental behavior was also related to self-esteem. Many differences in parent and child perspectives were noted. These findings may have implications in the future development of prevention and intervention techniques for children at risk for anxiety

Co-Occurring Conduct Problems and Anxiety: Implications for the Functioning and Treatment of Youth with Oppositional Defiant Disorder

Conduct problems and anxiety symptoms commonly co-occur among youths with oppositional defiant disorder (ODD); however, how these symptoms influence functioning and treatment outcomes remains unclear. This study examined subtypes based on these co-occurring symptoms in a clinical sample of 134 youths (Mage = 9.67, 36.6% female, 83.6% white) with ODD and the predictive power of these subgroups for youth functioning and psychosocial treatment outcomes. The latent profile analysis (LPA) was used to identify subgroups based on parent- and self-reported conduct problems and anxiety symptoms. Differences among the subgroups in clinician-, parent-, and/or self-reported accounts of symptom severity, school performance, underlying processing known to be impaired across ODD, conduct and anxiety disorders, self-concept, and psychosocial treatment outcomes were examined. Four distinct profiles were identified: (1) Low Anxiety/Moderate Conduct Problems (n = 42); (2) High Anxiety/Moderate Conduct Problems (n = 33); (3) Moderate Anxiety/Moderate Conduct Problems (n = 40); and (4) Moderate Anxiety/High Conduct Problems (n = 19). The Moderate Anxiety/High Conduct Problems group exhibited more severe behavioral problems, greater difficulties with negative emotionality, emotional self-control, and executive functioning; they also demonstrated worse long-term treatment outcomes than the other subgroups. These findings suggest more homogeneous subgroups within and across diagnostic categories may result in a deeper understanding of ODD and could inform nosological systems and intervention efforts

Póster: Relevamiento y catalogación del patrimonio construido del ferrocarril Rosario- Puerto Belgrano. indagación sobre uno de los ferrocarriles franceses en Argentina.

El proyecto propone revisitar la producción edilicia el Ferrocarril Rosario Puerto Belgrano (FCRPB), empresa de capitales franceses que gestionó la concesión de la ruta en 1903, proponiendo un recorrido que teóricamente le permitiría enfrentar ventajosamente a las compañías británicas que ya operaban en el territorio. Parte de la estrategia de la empresa consistió en habilitar el servicio prácticamente en forma completa en 1910, lo que obligó a que tanto la ejecución del tendido como las numerosas obras civiles necesarias para su operación se completaran en forma acelerada y con varios frentes de obra simultáneos. Entre estas, resultan distintivas las estaciones realizadas por la compañía que presentan un caso muy interesante de diseño modular, adaptable a las necesidades de cada localidad, en función de la jerarquía de la estación en sí (primera, segunda o tercera categoría), y los servicios complementarios que tuviera la misma (triaje de material rodante, talleres, mesa de giro de locomotoras). La presente instancia del trabajo presenta el relevamiento pormenorizado de las estaciones de este ferrocarril, ubicadas en el espacio santafesino, desde la terminal de la red en la estación Rosario hasta la estación San Gregorio ubicada en el sureste provincial, sector de la provincia en el que este ferrocarril cumplió un rol estructurante del territorio, en momentos en que en el mismo se estaba produciendo la transición de la actividad ganadera a la producción cerealera, con el auge del cultivo de maíz y la expansión del arriendo agrícola. En este aspecto el FCRPB merece una atención particular, puesto que en función de las características únicas de su trazado - un arco que desde Rosario planteó el vínculo con el entonces nuevo puerto atlántico bonaerense -posibilitó la consolidación de nuevos centros poblados. Las innovaciones implícitas en el proyecto del FCRPB y de sus edificios, en los que se hacen evidentes conceptos de racionalización y simplificación propios del pensamiento industrial del siglo XX, permiten diferenciar la obra construida de este ferrocarril dentro del conjunto de la arquitectura ferroviaria producida por las múltiples empresas que se instalaron en la provincia desde poco después de la mitad del siglo XIX y hasta el inicio de la Primera Guerra Mundial.En este aspecto, la obra del FCRPB presenta criterios de simplicidad y economía de recursos que la distinguen de las formas tradicionalmente asociadas al concepto de arquitectura ferroviaria, presentando una alternativa a las habituales formas ligadas a la tradición funcional inglesa.Fil: Benedetti, Rubén - Universidad Nacional de Rosario.

Fortune telling: metabolic markers of plant performance

International audienceBackground: In the last decade, metabolomics has emerged as a powerful diagnostic and predictive tool in many branches of science. Researchers in microbes, animal, food, medical and plant science have generated a large number of targeted or non-targeted metabolic profiles by using a vast array of analytical methods (GC–MS, LC–MS, 1H-NMR….). Comprehensive analysis of such profiles using adapted statistical methods and modeling has opened up the possibility of using single or combinations of metabolites as markers. Metabolic markers have been proposed as proxy, diagnostic or predictors of key traits in a range of model species and accurate predictions of disease outbreak frequency, developmental stages, food sensory evaluation and crop yield have been obtained. Aim of review : (i) To provide a definition of plant performance and metabolic markers, (ii) to highlight recent key applications involving metabolic markers as tools for monitoring or predicting plant performance, and (iii) to propose a workable and cost-efficient pipeline to generate and use metabolic markers with a special focus on plant breeding. Key message: Using examples in other models and domains, the review proposes that metabolic markers are tending to complement and possibly replace traditional molecular markers in plant science as efficient estimators of performance
