El rol de la presencia de un área silvestre protegida en el desarrollo local. Un estudio de caso en la Región de Aysén, Patagonia chilena / / / \ \ \…

2020

Resumen: Para probar si el desarrollo de una pequeña localidad puede ser impulsado por el turismo asociado a la presencia en su cercanía de un área silvestre protegida, se estudió el caso de Villa Cerro Castillo, en la Región de Aysén, Patagonia chilena. Para ello se hizo un reconocimiento de los emprendimientos turísticos en la localidad y se caracterizó a los prestadores de servicio en el lugar. Para evaluar la evolución de la dotación de servicios turísticos, se comparó la situación del año 2019 con la del año 2006. Como resultado pudo comprobarse que la existencia de servicios turísticos se multiplicó por 1,5 en los 19 años del presente siglo, manifestando, además, una mayor calidad y v…

Measurement error in schooling data: the OECD case

2003

The effect of human capital is difficult to estimate in cross-country analysis due to measurement errors in schooling data. Using data for OECD countries over the period 1960–1990, the reliability of the widely used Barro and Lee's data set and also the new De la Fuente and Domenech's data set is analysed. Results show that both suffer from measurement errors, but the latter seems to reflect the rate of growth of schooling more accurately, especially when taking long differences.

Star-polynomial identities: computing the exponential growth of the codimensions

2017

Abstract Can one compute the exponential rate of growth of the ⁎-codimensions of a PI-algebra with involution ⁎ over a field of characteristic zero? It was shown in [2] that any such algebra A has the same ⁎-identities as the Grassmann envelope of a finite dimensional superalgebra with superinvolution B. Here, by exploiting this result we are able to provide an exact estimate of the exponential rate of growth e x p ⁎ ( A ) of any PI-algebra A with involution. It turns out that e x p ⁎ ( A ) is an integer and, in case the base field is algebraically closed, it coincides with the dimension of an admissible subalgebra of maximal dimension of B.

The growth of “black crusts” on calcareous building stones in Palermo (Sicily): a first appraisal of anthropogenic and natural sulphur sources

2008

Chemical, mineralogical and isotopic composition (34S/32S) analyses were carried out on “black crusts” developed on the old buildings of Palermo (Sicily) with the aim to distinguish between natural and anthropogenic sulphur sources. Furthermore individual samples of total suspended particulate (TSP) were collected and analysed in order to estimate the influence of air pollution on the decay process of calcareous stones in a typical southern Mediterranean coastal environment. SEM/EDS analysis, X-ray diffractometry, IR spectroscopy and liquid chromatography led to the compositional characterization of “black crusts” and airborne particulate matter in the city. Sulphur isotopic compositions of…

Elasticity as a measure for online determination of remission points in ongoing epidemics.

2020

The correct identification of change-points during ongoing outbreak investigations of infectious diseases is a matter of paramount importance in epidemiology, with major implications for the management of health care resources, public health and, as the COVID-19 pandemic has shown, social live. Onsets, peaks, and inflexion points are some of them. An onset is the moment when the epidemic starts. A "peak" indicates a moment at which the incorporated values, both before and after, are lower: a maximum. The inflexion points identify moments in which the rate of growth of the incorporation of new cases changes intensity. In this study, after interpreting the concept of elasticity of a random va…

Rate of growth of frequently hypercyclic functions

2010

AbstractWe study the rate of growth of entire functions that are frequently hypercyclic for the differentiation operator or the translation operator. Moreover, we prove the existence of frequently hypercyclic harmonic functions for the translation operator and we study the rate of growth of harmonic functions that are frequently hypercyclic for partial differentiation operators.

Mode and Rate of Growth in Ammonoids

1996

In this chapter we discuss the mode and rate of growth in ammonoids, focusing primarily on postembryonic growth. We first discuss the general mode of growth and then describe the ontogenetic sequence of growth stages. These stages are recognized on the basis of changes in morphology. For example, a graph of the increase in size of whorl width versus shell diameter in an individual reveals changes through ontogeny that pinpoint the end of one growth stage and the beginning of another. We next discuss the overall rate of growth through ontogeny and establish a generalized growth curve. In this discussion, we refer to other cephalopods whose rate of growth is known. Fluctuations in the rate of…

2017

The aim of this article is to analyze the changes in the structure of growth of animals for slaughter production in the Polish regions in the years 2004–2014, according to the sector of animals for slaughter using the classical shift share method. The study evaluates the rate of growth of volumes of animals for slaughter production. Furthermore, it identifies and estimates the share of structural and regional changes in the size of the effect of the global (total animals for slaughter production in Poland) in the regional breakdown.

Reducing Relationship Conflict in Virtual Teams With Diversity Faultlines: The Effect of an Online Affect Management Intervention on the Rate of Grow…

2020

The aim of this study was to analyze the effect of an online affect management intervention on relationship conflict through the rate of growth of team resilience in virtual teams with diversity faultlines. Fifty-two 4-person teams participated in a randomized controlled trial design with repeated measures (i.e., three measurement occasions). Teams were randomly assigned to either an intervention designed to help them manage emotions in virtual teams or a control condition. Our findings showed that affect management can reduce the level of relationship conflict in virtual teams with diversity faultlines and that this effect can be explained by the pattern of change in team resilience in re…
