Dark matter spikes in the vicinity of Kerr black holes

The growth of a massive black hole will steepen the cold dark matter density at the center of a galaxy into a dense spike, enhancing the prospects for indirect detection. We study the impact of black hole spin on the density profile using the exact Kerr geometry of the black whole in a fully relativistic adiabatic growth framework. We find that, despite the transfer of angular momentum from the hole to the halo, rotation increases significantly the dark matter density close to the black hole. The gravitational effects are still dominated by the black hole within its influence radius, but the larger dark matter annihilation fluxes might be relevant for indirect detection estimates.Comment: Published version plus corrected typo in Fig 1

El concepte d'aristocràcia espiritual en el llibre primer del Kuzari

Revista d'història i cultura jueves". Medalla Ramon Llull de la Comunitat de les Illes Balears (2007) (Correu electrònic: [email protected]).L'objectiu del present treball és mostrar, a través del Llibre Primer del Kuzari, de Iehudà Haleví, traduït per primera vegada al català pel rabí Jordi Gendra, una de les primeres formulacions sobre l'origen aristocràtic del poble jueu, defensat per un dels poetes més importants del judaisme de la Diàspora. A través d'una selecció d'origen diví, Israel es constitueix en l'autèntica aristocràcia del món, ja que per la seva condició de poble profètic se situa molt per damunt de la resta dels pobles, i tan sols superats en l'escala de la Creació pels àngels.The objective of the following work is showing, through the First Book of Kuzari, by Iehuda Halevi, firstly translated into Catalonian by Rabbi Jordi Gendra, one of the first formulations of the aristocratic origin of the Jewish population, defended by one of the most important poets of Judaism during the Jewish Diaspora. The book explains that through a divine selection, Israel is constituted as the authentic aristocracy of the world, due to its condition of a prophetic population it is situated over the rest of populations and in the Creational scale it's only superadded by angels

Organización escolar y rendimiento

Treball de Final de Grau en Mestre o Mestra d'Educació Primària. Codi: MP1040. Curs acadèmic 2014-2015Tomando como punto de partida la organización escolar como forma de mejorar los resultados académicos, se ha llevado a cabo una comparativa a lo largo de la historia reciente de la escolaridad, acerca de cómo un buen funcionamiento y una buena sincronización de todas las partes y procesos implicados en la organización escolar, va acompañado de un aumento en el rendimiento del alumnado. Desde los métodos iniciales consistentes en la repetición constante hasta lograr la interiorización de los contenidos, pasando por la memorización sin comprensión con el único fin de aprobar un examen, se ha llegado a la época actual, en la cual se le otorga una importancia fundamental al hecho de que aquello que se enseña en las aulas debe tener un alto componente de significación para el alumno/a, como la mejor forma de que este contenido pase a formar parte del bagaje cultural del mismo, y, además, lo adquiera de forma permanente. La evolución en el modo de transmitir los contenidos y en la forma de trabajar en el aula, utilizando todas las posibilidades a nuestro alcance y un gran número de materiales de diversa índole, ofrece, como consecuencia, un aumento en la cantidad y calidad de los contenidos asimilados. Pero la observación de todo este camino, lleva a pensar que no todo está inventado en el campo de la organización escolar, y, por tanto, se debe seguir trabajando para mejorar y encontrar aquellos métodos organizativos y aquellos procesos que lleven a la mejora del rendimiento en las aulas

Gender Gaps in Performance: Evidence from Young Lawyers

This paper documents and studies the gender gap in performance among associate lawyers in the United States. Unlike other high-skilled professions, the legal profession assesses performance using transparent measures that are widely used and comparable across firms: the number of hours billed to clients and the amount of new client revenue generated. We find clear evidence of a gender gap in annual performance with respect to both measures. Male lawyers bill ten percent more hours and bring in more than twice the new client revenue than do female lawyers. We demonstrate that the differential impact across genders in the presence of young children and differences in aspirations to become a law firm partner account for a large share of the difference in performance. We also show that accounting for performance has important consequences for gender gaps in lawyers’ earnings and subsequent promotion. Whereas individual and firm characteristics explain up to 50 percent of the earnings gap, the inclusion of performance measures explains a substantial share of the remainder. Performance measures also explain a sizeable share of the gender gap in promotion

The importance of early parenting for later child outcomes: A study with Spanish families with children with disabilities

Children with different disability conditions have varied developmental trajectories, which perhaps influences parent-child interaction. For these and all infants, an optimal home environment that includes good parenting and positive parent-child interactions predicts better developmental outcomes (Spiker et al., 2005). Interventions using a family-centered, parenting-focused approach result in better parenting behavior that contributes to improved early child development (Avellar & Suplee, 2013; Roggman & Cardia, 2016). Information on parent-child interaction patterns is needed to guide intervention in natural contexts of families (Fuligni & Brooks-Gunn, 2013). Parent-child interaction data were collected from 44 mothers and 35 fathers interacting with their children (23 to 47 months) who had a disability and were in one of eight Spanish Early Interventions Centers. Mothers and fathers, separately, auto-recorded 10-minute play sessions at home. Parental interactions were assessed using PICCOLO (Roggman et al., 2013), a standardized measure of parenting. Two independent observers coded the interactions; strong intra-class correlation coefficients were found (.82 to .97 for mothers, .77 to .89 for fathers). The BSID-III scales (Bayley, 2015) assessed children’s development. Mothers scored slightly higher than did fathers. Scores varied by PICCOLO domains but were consistent with other PICCOLO studies of typical developing children (Roggman et al., 2013). Mother and father’s scores correlated indicating that the higher the scores of mothers in any dimension correlated with those of the parents combined. Positive significant Pearson correlations were found between parenting and child’s development with different patterns of father and mother domains predicting better language and cognitive outcomes. Although barriers to optimal parenting need further investigation, PICCOLO can be a useful tool to support optimal parenting.Universidad de Málaga. Campus de Excelencia Internacional Andalucía Tech
