Accounting for Cross-Country Income Differences with Public Capital

This paper offers new evidence on the sources of cross-country income differences by investigating the role public capital in development accounting. I explicitly measure private and public capital stocks, and I find large differences in both types of capital across countries. Moreover, differences in private capital are larger than the ones I find for total capital for the richest and poorest countries. The methodology I use implies a share of publica capital in output of at most 10%. My findings indicate that differences in capital stocks can not account for a substantial part of the observed dispersion in income across countries.Income differences, Public capital, Development Accounting.

Distortions, Infrastructure and Labor Supply in Latin American Countries

I document differences in labor supply between a set of Latin American countries and the U.S, in the period 1990-2005. These differences are mostly explained by large differ-´ ences in female labor supply. In the U.S. the female labor force participation was 69% by 1990, while in Brazil and Mexico was 39% and 37%, respectively. Females began to participate more in the labor market of these countries when more households acquired access to basic infrastructure and when distortive policies affecting the price of household appliances were partially removed. I use a model of home production with endogenous labor force participation to account fore these facts. I conclude that the price of household appliances and access to infrastructure are quantitatively important in explaining cross-country labor supply differences.Labor Force Participation, Latin America, Policy Distortions, Household Appliances.

Social Insurance and Occupational Mobility

This paper studies how insurance from progressive taxation improves the matching of workers to occupations. We propose an equilibrium dynamic assignment model to illustrate how social insurance encourages mobility. Workers experiment to find their best occupational fit in a process filled with uncertainty. Risk aversion and limited earnings insurance induce workers to remain in unfitting occupations. We estimate the model using microdata from the United States and Germany. Higher earnings uncertainty explains the U.S. higher mobility rate. When workers in the United States enjoy Germany’s higher progressivity, mobility rises. Output and welfare gains are large

Trastornos mentales y su relación con la dinámica familiar en el departamento de Santa Bárbara

This article aims to analyze the prevalence of mental disorders and their relationship with family dynamics in the adult population of the department of Santa Barbara. The research methods are based on a descriptive, quantitative, cross-sectional design with a polyvalent sampling with selection criteria in which 300 houses were surveyed, using as instruments the WHO Symptom Questionnaire for Adults (SRQ), Detection of probable mental disorders symptomatology and the Family Functioning Questionnaire (FFSL) of Ortega and Co. We worked with the SPSS program to obtain the analytical results of the research. The most prevalent mental disorders were depression, followed by post-traumatic stress, anxiety, drug dependence. The less prevalent mental disorders were alcohol dependence and epilepsy. The highest frequency of probable mental disorders is in the female gender, people over 51 years of age, and people who remain single. In relation to the families of Santa Bárbara that present functional family dynamics, that is to say, that the greater the family functioning, the less presence of mental disorders. In conclusion, the prevalence of probable mental disorders in the department of Santa Barbara is higher than that reported by the WHO (2002), which represents a challenge for the Honduran health system and demonstrates the need to focus the care and resources towards the prevention, promotion, and treatment of mental disorder.Este artículo tiene el objetivo de analizar la prevalencia de los trastornos mentales y su relación con la dinámica familiar en la población adulta del departamento de Santa Bárbara. Los métodos en la investigación se basa en un diseño descriptivo, cuantitativo, de corte trasversal con un muestreo polietápico con criterios de selección en donde fueron encuestadas 300 viviendas, utilizando como instrumentos el Cuestionario de Síntomas para adultos (SRQ) propuesto por la OMS para la detección de sintomatología probables trastornos mentales y el Cuestionario de funcionamiento familiar (FFSL) de Ortega y Colaboradores. Se trabajó con el programa SPSS para obtener los resultados analíticos de la investigación. Los trastornos mentales de mayor prevalencia son la depresión, seguido de estrés postraumático, ansiedad, dependencia a las drogas, en menor porcentaje se encuentra la dependencia al alcohol y epilepsia. La mayor frecuencia de los probables trastornos mentales es en el género femenino, así como las personas mayores de 51 años, de la misma forma los solteros (as). En relación a las familias de Santa Bárbara que presentan dinámica familiar funcional es decir que a mayor funcionamiento familiar menor presencia de trastornos mentales. En conclusión la prevalencia de probables trastornos mentales en el departamento de Santa Bárbara es mayor a lo reportado por la OMS (2002) por lo que representa un reto para el sistema de salud hondureño y demuestra la necesidad de enfocar la atención y recursos hacia la prevención, promoción y tratamiento oportuno de los trastornos mentales

Vibrations loads in the process of designing scientific spacecraft payloads

Scientific missions constitute fundamental cornerstones of space agencies such as ESA and NASA. Modern astronomy could not be understood without the data provided by these missions. Scientists need to design very carefully onboard instruments. Payloads have to survive the crucial launch moment and later perform well in the really harsh space environ-ment. It is very important that the instrument conceptual idea can be engineered to sustain all those load

The importance of T ... T ... T angles in the feasibility of zeolites

The database of prospective zeolites (www. hypotheticalzeolites.net) has been screened in search of feasible zeolites. Previous criteria of zeolite feasibil- ity have been reviewed, based on descriptors such as energy, density, average and distribution of ring sizes, and more importantly that of Li et al. (LID criteria) presented recently [Angew. Chem. Int. Ed. 2013, 52, 1673], based on Si O, O ... O, and Si ... Si distances of SLC-minimised struc- tures. In spite of the still large number of feasible zeolites according to this and other criteria, a number of research- ers wonder why there are so many feasible and so few synthesised zeolites. Without answering this difficult question, a new criteria is proposed in this study based on the fact that T ... T ... T angles (T is tetrahedral atom) show spe- cific ranges of values depending on the ring size to which they belong. Based on improved definitions to count and enumerate rings in zeolites, and with data from the IZA database, we introduce the TTT criteria, which we propose to use after the LID criteria, to further narrow the space of feasible zeolites.We thank ASIC computational centre of UPV for making available their computational resources.

Detection of SARS-CoV-2 infection by saliva and nasopharyngeal sampling in frontline healthcare workers: An observational cohort study

Background The SARS-CoV-2 pandemic has caused an unprecedented strain on healthcare systems worldwide, including the United Kingdom National Health Service (NHS). We conducted an observational cohort study of SARS-CoV-2 infection in frontline healthcare workers (HCW) working in an acute NHS Trust during the first wave of the pandemic, to answer emerging questions surrounding SARS-CoV-2 infection, diagnosis, transmission and control. Methods Using self-collected weekly saliva and twice weekly combined oropharyngeal/nasopharyngeal (OP/NP) samples, in addition to self-assessed symptom profiles and isolation behaviours, we retrospectively compared SARS-CoV-2 detection by RT-qPCR of saliva and OP/NP samples. We report the association with contemporaneous symptoms and isolation behaviour. Results Over a 12-week period from 30th March 2020, 40∙0% (n = 34/85, 95% confidence interval 31∙3-51∙8%) HCW had evidence of SARS-CoV-2 infection by surveillance OP/NP swab and/or saliva sample. Symptoms were reported by 47∙1% (n = 40) and self-isolation by 25∙9% (n = 22) participants. Only 44.1% (n = 15/34) participants with SARS-CoV-2 infection reported any symptoms within 14 days of a positive result and only 29∙4% (n = 10/34) reported self-isolation periods. Overall agreement between paired saliva and OP/NP swabs was 93∙4% (n = 211/226 pairs) but rates of positive concordance were low. In paired samples with at least one positive result, 35∙0% (n = 7/20) were positive exclusively by OP/NP swab, 40∙0% (n = 8/20) exclusively by saliva and in only 25∙0% (n = 5/20) were the OP/NP and saliva result both positive. Conclusions HCW are a potential source of SARS-CoV-2 transmission in hospitals and symptom screening will identify the minority of infections. Without routine asymptomatic SARS-CoV-2 screening, it is likely that HCW with SARS-CoV-2 infection would continue to attend work. Saliva, in addition to OP/NP swab testing, facilitated ascertainment of symptomatic and asymptomatic SARS-CoV-2 infections. Combined saliva and OP/NP swab sampling would improve detection of SARS-CoV-2 for surveillance and is recommended for a high sensitivity strategy
