Fiscal policy and indeterminacy in models of endogenous growth

This paper investigates the dynamic behavior of two-sector models of endogenous growth with sector-specific external effects, and government expenditure financed by distortionary taxation. When this type of external effect is combined with a sufficient degree of capital taxation in a Lucas–Uzawa endogenous growth model, continua of equilibria will emerge in the region of the balanced growth paths. By contrast, indeterminacy is not possible when either sector-specific external effects or factor taxation are added to the model in isolation. In the second part of the paper, we demonstrate that if labor supply is endogenous, indeterminacy can be consistent with much lower degrees of increasing returns to scale. Furthermore, certain types of fiscal policy will be associated with multiple balanced growth paths and the existence of a poverty trap. Finally, in the last part of the paper, we demonstrate that if physical capital is employed in both sectors of the economy, indeterminacy will emerge for varying combinations of factor taxation and external effects, even when returns to scale are constant at the social level

Factores maternos y neonatales asociados con la presencia de líquido amniótico meconial en gestantes atendidas en Hospital Distrital Jerusalén - La Esperanza - Trujillo 2017

Objetivo: Determinar los factores maternos y neonatales asociados con la presencia de líquido amniótico meconial (LAM). Material y métodos: Se realizó un estudio de casos y controles evaluándose 234 gestantes de 38 a 40 semanas con parto vaginal, las cuales fueron dividas en 2 grupos: 78 con presencia de LAM y 176 sin presencia de LAM. Se calculó el OR y prueba chi cuadrado para cada factor y se corroboró lo encontrado utilizando regresión logística binaria. Resultados: Se obtuvo que los siguientes factores presentaron significancia estadística (p<0.05) tanto para el análisis bivariado como multivariado: Uso de oxitócicos OR c = 4.02 (IC 95% 2.09 – 7.76) y OR a = 4.43 (IC 95% 2.16 – 9.01); Anemia en el embarazo OR c = 2.47 (IC 95% 1.39 – 4.37) y OR a = 2.35 (IC 95% 1.27 -–4.37); Distocia funicular OR c = 3.70 (IC 95% 2.07 – 6.35) y OR a = 3.57 (IC 95% 1.94 – 6.58). También se encontró que el peso del recién nacido y la distocia relativa presentaron significancia estadística en el análisis multivariado: OR a = 3.11 (IC 95% 1.21 – 8.06) y OR a = 2.91 (IC 95% 1.25 – 6.76) respectivamente. No se encontró significancia estadística para los factores paridad, edad materna, infección de tracto urinario, atenciones prenatales e índice de masa corporal. Conclusiones: La anemia en el embarazo, el uso de oxitócicos, el peso del recién nacido, la distocia relativa y la distocia funicular son los únicos factores asociados con la presencia de LAMObjective: To determine the maternal and neonatal factors associated with the presence of meconium stained amniotic fluid (MSAF) Material and methods: A case-control study was conducted, evaluating 234 pregnant women from 38 to 40 weeks with vaginal delivery, which were divided into 2 groups: 78 with the presence of MSAF and 176 without the presence of LAM. The OR and chi square test were calculated for each factor and the findings were corroborated using binary logistic regression. Results: The following factors were found to have statistical significance (p <0.05) for both bivariate and multivariate analyzes: Use of oxytocics OR c = 4.02 (CI 95% 2.09 - 7.76) and OR a = 4.43 (CI 95% 2.16 - 9.01); Anemia in pregnancy OR c = 2.47 (CI 95% 1.39 - 4.37) and OR a = 2.35 (CI 95% 1.27 - 4.37), Funicular dystocia OR c = 3.70 (CI 95% 2.07 - 6.35) and OR a = 3.57 (CI 95% 1.94) - 6.58). It was also found that the newborn weight and relative dystocia presented statistical significance in the multivariate analysis: ORa = 3.11 (CI 95% 1.21 - 8.06) and ORa = 2.91 (CI 95% 1.25 - 6.76) respectively. No statistical significance was found for the factors parity, maternal age, urinary tract infection, prenatal care and body mass index. No statistical significance was found for the factors parity, maternal age, urinary tract infection, prenatal care and body mass index. Conclusions: Anemia in pregnancy, the use of oxytocics, newborn weight, relative dystocia and funicular dystocia are the only factors associated with the presence of MSAFTesi

An Advanced Pavement Management System based on a Genetic Algorithm for a Motorway Network

Maintenance and improvement, through the rehabilitation, of the road infrastructure is a strategic and priority objective for road agencies, nevertheless the economic resources required are often inadequate. Within road management, the pavement management system (PMS) plays an essential role because of both the money needed and the performance that should be provided in terms of safety, ride quality and transport cost. The PMS is based on searching for a balanced solution between the lowest cost and the increased level of performance (i.e. pavement condition). In this paper a PMS multi-objective optimization method, was proposed, using a genetic algorithm (GA) to identify the best solution considering different rehabilitation strategies. The multi-objective optimization GA permits a set of optimal solutions (the Pareto solution set) that takes into account all the considered constraints. Finally on the basis of a specific criteria the best solution was selected in relation to the ranking of the priorities of the agency. A detailed numerical study was conducted on the Italian A18 motorway and the results showed that the proposed model PMS-GA is a suitable support to the decision making process

HISAR : hydrologic Indices of South American Rivers

This is a preview of the HISAR dataset (Hydrologic Indices of South American Rivers). The HISAR dataset is freely available for non-commercial use. The files provided are (i) drainage line shapefile with river reaches as represented by the MGB model and 73 attributes corresponding to hydrologic indices derived from simulated time series; (ii) gauge points shapefile with 73 attributes corresponding to hydrologic indices derived from observed time series; (iii) maps with hydrologic indices, (iv) maps with information of the error of some indices and (v) the scripts used to calculate the indices. This database provides a spatial view of the variability of the river flow regime characteristics. The line shapefile has 33,749 river reaches with an average length of 15 km and drainage area > 1000 km². The ESRI shapefile also has the attributes of drainage area (Upst_Area_ in km²), length (Ltr_Km_ in km), UC (corresponding catchment attribute from hydrological modelling), HYear_min (starting month of the hydrological year of minimum flow) and HYear_max (starting month of the hydrological year of maximum flow). A value of -9999999 is used as a symbol of ‘no data’. Some river reaches do not have all hydrologic indices calculated, due to series of streamflows that could not meet specific criteria. For instance, the baseflow recession constant was automatically calculated using at least five consecutive days of decreasing streamflow, all of which below the Q90 (streamflow value that is exceeded 90% of the time), and this condition was not found in all cases. The gauge points shapefile has 1329 points with 73 attributes corresponding to hydrologic indices derived from observed time series. The drainage area of the gauges ranging from 1,000 to 4,703,503 km2. The ESRI shapefile also has the attributes of code, name, latitude (lat), longitude (long), drainage area (Upst_Area_ in km²), Country were the gauge point are located, HYear_min (starting month of the hydrological year of minimum flow) and HYear_max (starting month of the hydrological year of maximum flow). A value of -9999999 is used as a symbol of ‘no data’. For more information about HISAR dataset see the journal article DOI: in preparation

Campo santo ecológico para mitigar el déficit de la infraestructura funeraria, José Leonardo Ortiz, La Victoria y Chiclayo

Se plantea el desarrollo de una propuesta de creación de un Camposanto ecológico para el mejoramiento de la infraestructura fúnebre deteriorada con un estudio que abarca los tres principales distritos de Chiclayo: José Leonardo Ortiz, Chiclayo y La Victoria; que tiene como finalidad que el entierro a sus seres queridos sea seguro y dentro de un establecimiento que pueda brindar todos los servicios fúnebres a sus visitantes. El sector muestra que sus actuales establecimientos fúnebres están deteriorados, y no cuentan con los servicios básicos para su desarrollo. Las primeras propuestas de cementerios ecológicos se realizaron en España a causa de la sobrepoblación mortuoria y para implementar el tema ecológico apoyando así al planeta, se implementaron varios tipos de entierros, y cremaciones que cumplan con ciertos estándares. En el ámbito local, Chiclayo, José Leonardo Ortiz y La Victoria se encontró un 70% de déficit de cementerios, en el cual se tomó en cuenta el cementerio público el Carmen contando con un 75% de déficit, Jardines de la Paz, con un 37.5, El Ángel con un 62.5 y el recién construido Esperanza Eterna con un 0% de déficit. Por lo que se llegó a la conclusión que con estos porcentajes no se es abasto para que los 3 distritos entierren a sus fallecidos. Se realizará un estudio cualitativo- critica- proyectiva por lo que la investigación formará parte de un diseño con contenido expuesto en el planteamiento del problema, estos elementos se constituyen en una organización principal, con: se observa, debido, ocasiona y consecuencia; la característica principal de este sistema es la dinámica con un bucle de una creación de campo santo ecológico para el mejoramiento de la infraestructura fúnebre deteriorada en los distritos de José Leonardo Ortiz, Chiclayo, La VictoriaTesisInfraestructura, Tecnología y Medio Ambient
