Sigma pole position and errors of a once and twice subtracted dispersive analysis of pi-pi scattering data
We show how the new precise data on kaon decays together with forward
dispersion relations, sum rules and once- and twice-subtracted
Roy's equations allow for a precise determination of the sigma meson pole
position. We present a comparison and a study of the different sources of
uncertainties when using either once- or twice-subtracted Roy's equations to
analyze the data. Finally we present a preliminary determination of the sigma
pole from the constrained dispersive data analysis.Comment: 4 pages, 6 figures. Contribution to the proceedings of the QCD08 14th

Profile of residents: attitude towards tourism in Benalmádena (Costa del Sol, Spain)
Tourism development and evolution along the time causes multiple impacts. Based on characteristic profiles of resident, these impacts may be assessed differently. The attitude of residents and the identification of profiles is a tool that allows to asses the status of destination and propose future strategies for improving the destination. This study aims to analyse the role of residents regarding the perception of tourism.Universidad de Málaga. Campus de Excelencia Internacional Andalucía Tech.

Gestión del bienestar social y su relación con la felicidad laboral de los colaboradores administrativos en una universidad privada de Trujillo - 2020
La investigación desarrollada tuvo como problema principal: ¿Cuál es la relación
que existe entre la gestión del bienestar social y la felicidad laboral de los
colaboradores administrativos en una universidad privada de Trujillo – 2020?, a
partir de ello, se planteó como objetivo general determinar la relación entre gestión
del bienestar social y la felicidad laboral de los colaboradores administrativos en
una universidad privada de Trujillo – 2020. En donde se utilizó una metodología de
tipo básica con una técnica de contrastación correlacional, y un diseño no
experimental, además se contó con una muestra compuesta por 244 trabajadores
administrativos, la cual se halló mediante el empleo de fórmula estadística; a estos
trabajadores administrativos se le aplicó encuesta usando el software google form,
con dos cuestionarios elaborados, de 33 y 23 preguntas correspondiente a las
variables gestión del bienestar social y felicidad laboral respectivamente. Los
resultados se presentaron mediante tablas y figuras, donde en primer lugar se
verificó la existencia de una eficiente gestión del bienestar social según el 50.2%
de los resultados, mientras que el 42.7% evidenció un nivel alto en la felicidad
laboral del trabajador. Finalmente, se llegó a concluir que la gestión de bienestar
social se relaciona directa y positivamente con la felicidad laboral de los
colaboradores administrativos en una universidad privada de Trujillo-2020.The main problem of the research carried out was: what is the relationship between
the management of social welfare and the job happiness of the administrative
collaborators in a private university in Trujillo - 2020? between social welfare
management and job happiness of administrative collaborators in a private
university in Trujillo - 2020. Where a basic type of methodology was used with a
correlational contrast technique, and a non-experimental design, in addition there
was a sample composed of 244 administrative collaborators, which was found by
using a statistical formula; a survey was applied to these workers, by means of two
questionnaires of 33 and 23 questions corresponding to the variable’s management
of social welfare and job happiness, respectively. The results were presented by
means of tables and figures, where in the first place the existence of an efficient
management of social welfare was verified according to 50.2% of the results, while
42.7% showed a high level of worker happiness at work. Finally, it was concluded
that the management of social welfare is directly and positively related to the job
happiness of administrative collaborators in a private university in Trujillo - 2020Tesi
New dispersion relations in the description of scattering amplitudes
We present a set of once subtracted dispersion relations which implement
crossing symmetry conditions for the scattering amplitudes below 1
GeV. We compare and discuss the results obtained for the once and twice
subtracted dispersion relations, known as Roy's equations, for three
partial JI waves, S0, P and S2. We also show that once subtracted dispersion
relations provide a stringent test of crossing and analyticity for
partial wave amplitudes, remarkably precise in the 400 to 1.1 GeV region, where
the resulting uncertainties are significantly smaller than those coming from
standard Roy's equations, given the same input.Comment: 8 pages, 2 figures, to appear in the Proceedings of the Meson 2008
