    Purpose: To describe the morbidity and mortality of very low birth weight (VLBW) infant graduates of a level three neonatal intensive care unit (NICU) in a medically underserved population. Design: A retrospective chart analysis of 181 live born infants at a regional tertiary center between 2004-2006. Sample: Infants born with a birth weight of 425-1489 grams and gestational age of23-40 weeks (n=127). Main outcome variable: Descriptive statistics were used to describe the incidence of associated VLB W morbidities presenting after discharge along with hospital readmissions and mortality rates. Results: VLBW infants discharged from the NICU had chronic lung disease (24.4%), hearing loss (5.5%), seizures (3%), cerebral palsy (1.6%), mental retardation (0.8%), and visual loss (0.8%). They also showed abnormal neurodevelopmental findings (59%), speech/language disorders (12.5%) and behavioral/learning disorders (1.5%). One death (\u3c1%) was reported after discharge. Forty-five children (35%) were readmitted to the hospital after discharge accounting for 78 hospital admissions

    A new construction of homogeneous quaternionic manifolds and related geometric structures

    Let V be the pseudo-Euclidean vector space of signature (p,q), p>2 and W a module over the even Clifford algebra Cl^0 (V). A homogeneous quaternionic manifold (M,Q) is constructed for any spin(V)-equivariant linear map \Pi : \wedge^2 W \to V. If the skew symmetric vector valued bilinear form \Pi is nondegenerate then (M,Q) is endowed with a canonical pseudo-Riemannian metric g such that (M,Q,g) is a homogeneous quaternionic pseudo-K\"ahler manifold. The construction is shown to have a natural mirror in the category of supermanifolds. In fact, for any spin(V)-equivariant linear map \Pi : Sym^2 W \to V a homogeneous quaternionic supermanifold (M,Q) is constructed and, moreover, a homogeneous quaternionic pseudo-K\"ahler supermanifold (M,Q,g) if the symmetric vector valued bilinear form \Pi is nondegenerate.Comment: to appear in the Memoirs of the AMS, 81 pages, Latex source fil

    The Integrable Bootstrap Program at Large N and its Applications in Gauge Theory

    We present results for the large-NN limit of the (1+1)-dimensional principal chiral sigma model. This is an asymptotically-free N×NN\times N matrix-valued field with massive excitations. All the form factors and the exact correlation functions of the Noether-current operator and the energy-momentum tensor are found, from Smirnov's form-factor axioms. We consider (2+1)-dimensional SU(∞)SU(\infty) Yang-Mills theory as an array of principal chiral models with a current-current interaction. We discuss how to use our new form factors to calculate physical quantities in this gauge theory.Comment: Presented at the 31st International Symposium on Lattice Field Theory (Lattice 2013), 29 July - 3 August 2013, Mainz, Germany.

    Migrants’ social and labor market outcomes: Paraguayans in Argentina

    Get PDF
    This paper addresses some factors influencing migrants’ social and labor market outcomes in host countries, focusing particularly on the case of Paraguayan migration to Argentina. In the first decades of the 20th century, Latin America and the Caribbean received 15% of total migrant flows . In Argentina, in 1919, migrants represented 30% of the population, although this proportion diminished in the following decades. The share of migrants has remained around 4.5% to 5% of total Argentine population since 1995—until the 2010 Population Census—while the decline in European migration since the mid-1940s was replaced by neighboring countries’ migrants.Fil: Cortes, Rosalia Alba.
