TOURISM RESEARCH IN SPAIN: THE STATE OF THE ART
Alfonso Vargas-Sánchez
Enlightening Tourism : a Pathmaking Journal , 2011,
Abstract: This paper analyses the evolution that Tourism Research has undergone in Spain in the last few years as well as its present situation, on the basis of four different variables: (i) the PhD dissertations carried out in the last ten years; (ii) the papers published in any ISI source during the last five years; (iii) the scientific journals on Tourism edited in Spain; (iv) and finally, the active research groups, centres and networks concerned with Tourism that exist in the country at the moment. In general terms, it will be shown that, despite becoming more and more multidisciplinary and a subject mater of interest for a larger number of higher education institutions, the research carried out on Tourism in Spain seems to be still restricted to very few fields of knowledge, universities and regions.

Abstract: objective: to identify the coverage of a diabetic retinopathy screening program in primary health care and to assess agreement between ophthalmologists and family physicians (fp) regarding retinography evaluations of diabetic patients. materials and methods: cross-sectional observational study,with a review of diabetic patients' mydriatic retinographies (2007-2008) from three urban primary health centers (phc)(jaén-spain). results: a total of 296 retinographies in 2007 and 380 in 2008 (coverage=26%±2,4) were reviewed. pathological retinographies were identified by 181 fps (27%±1,3) and 59 (9%±0,3) ophthalmologists.total agreement was moderate (kappa=0,408±0,039).agreement was better in the latter year (0,45 vs 0,34; p<0,001 test χ2). fp evaluations showed 97% sensitivity,80% specificity,33% positive predictive value, 100% negative predictive value, 4, 88 positive likelihood ratio and 0,04 negative likelihood ratio. we find variability in coverage and agreement between phc. conclusions: mydriatic retinographies performed and evaluated by fps are useful to retinopathy screening of diabetic patients. coverage, predictive values and likelihood ratio were better in the latter year, although the interpretation should be homogenized.
El cooperativismo como fórmula empresarial de futuro para canalizar el espíritu emprendedor colectivo
Alfonso Vargas Sánchez
Revista Galega de Economía , 2001,
Abstract: Es un hecho que las formas empresariales de economía social, con la empresa cooperativa como principal exponente, vienen desempe ando un papel cada vez más activo y destacado en la sociedad contemporánea, en la que el fomento de la capacidad emprendedora se ha convertido en una de las prioridades de las políticas de empleo. Tanto es así que hay quien ha llegado a calificar la creación de empresas como el octavo arte. En la actualidad, el empresario se identifica con la figura del emprendedor, que cuando es colectivo encuentra en la cooperativa una fórmula cuyos perfiles idiosincrásicos sintonizan con determinados valores imperantes en nuestra sociedad. La empresa no puede ser ajena a lo que la sociedad de la que forma parte siente, desea, espera; al contrario, debe interiorizar esos valores y acomodar su comportamiento a ellos para darles a sus stakeholders justo lo que éstos demandan. La cultura del cooperativismo, empapada de democracia, de solidaridad, etc., nos ofrece precisamente eso, sin que se contraponga a la eficiencia en la gestión empresarial, que hace posible su supervivencia y desarrollo.
Evaluación de dos modalidades de manejo del pseudotallo después de la cosecha sobre el crecimiento, producción y sanidad de plantas de banano (Musa aaa)
Vargas Calvo,Alfonso; Cubillo Sánchez,Douglas;
Agronomía Costarricense , 2010,
Abstract: evaluation of two modalities of management of the pseudostem after the harvest on the growth, production and health of banana plants (musa aaa). in order to evaluate 2 modalities of common use in the management of the pseudostem after the harvest of the mother plant, 2 experiments were performed during the year 2006 in commercial banana (musa aaa, cv. grande naine) plantations in the caribbean region of costa rica. the treatments in both experiments were: 1-periodic elimination and 2-total retention, until collapse, of the deteriorated tissue of the pseudostem after harvest. growth, yield, diseases and insect- est variables were measured. except for the length of the second hand in experiment 1 (p=0.0309), and of the sixth hand in experiment 2 (p=0.0455), there were no differences between treatments in the remainder growth (p>0.1480) and production (p>0.0652) variables. presence of erwinia spp., soft rot was not observed. in both experiments, damage by larvae of cosmopolites sordidus was observed, which nevertheless was of little magnitude and only differed between treatments (p=0.0227) in experiment 2. corm rotting associate of with black weevil was only observed in experiment 1, at a low value, and with no differences between treatments (p>0.7574). the presence of pseudococcus elisae and periplaneta spp. was determined only in experiment 1; with both insects, the greater values (p<0.0412) were observed in treatment 2 (total retention). the presence of scales and aphids was not observed in either experiment. since there were not differences in growth and production between treatments, the selection of one of them would be given by risk factors associated with inse pest and/or common diseases to the banana crop.
Una aproximación teórica al contexto institucional de las políticas de gestión ambiental de los campos de golf Andaluces
Sánchez,Alfonso Vargas; Ligero,Francisco Riquel;
Revista Encontros Científicos - Tourism & Management Studies , 2009,
Abstract: in recent years the number of golf courses in the autonomous community of andalusia (spain) has increased exponentially. this sport has become one of the products with greater importance in tourist offer of andalusia, with significant economic impact in this territory. that is why there is a social debate about the environmental consequences of golf courses, in an attempt to reconcile economic development and respect for the natural environment. this debate has led to the generation of a highly institutionalized context that directly affects the environmental protection policies of such organizations. this paper aims to analyze the context and key practices derived from it.
Evaluación de dos modalidades de manejo del pseudotallo después de la cosecha sobre el crecimiento, producción y sanidad de plantas de banano (Musa AAA)
Alfonso Vargas Calvo,Douglas Cubillo Sánchez
Agronomía Costarricense , 2010,
Abstract: Durante el 2006 se realizaron 2 experimentos en plantaciones comerciales de banano (Musa AAA, cv. Grande Naine) del Caribe de Costa Rica. En ambos el primer tratamiento fue la eliminación periódica y el segundo la retención total, hasta el colapso, del tejido deteriorado del pseudotallo luego de la cosecha. Se midieron las variables de crecimiento, producción, enfermedades e insectos plagas. Excepto por el largo de la segunda mano en el experimento 1 (p=0,0309) y de la sexta mano en el experimento 2 (p=0,0455), no hubo diferencias entre tratamientos en las restantes variables de crecimiento (p>0,1480) y de producción (p>0,0652), ni presencia de pudrición por Erwinia spp. En ambos experimentos se observó la ocurrencia de da o por larvas de C. sordidus, pero éste, además de que fue de una baja magnitud, solo difirió entre tratamientos (p=0,0227) en el experimento 2. Se observó pudrición del cormo asociada con el picudo negro únicamente en el experimento 1, cuya expresión, además de ser baja, no difirió entre tratamientos (p>0,7574). Se determinó la presencia de Pseudococcus elisae y de Periplaneta spp., solamente en el experimento 1; con ambos insectos, los mayores valores (p<0,0412) se observaron en el tratamiento 2 (retención total). No se observó la presencia de escamas y áfidos en ninguno de los 2 experimentos. Dado que no hubo diferencias en crecimiento y producción entre tratamientos, la selección de uno de ellos estaría dada por factores de riesgo asociados con insectos plaga y/o enfermedades comunes al cultivo del banano.

Francisco José, Riquel Ligero,Alfonso, Vargas Sánchez
Visi?3n de futuro , 2012,
Abstract: This paper attempts an analysis of organizational motivations when developing policies for environmental liability. Specifically, to compare the production of social legitimacy to the improvement of organizational performance, we proceeded to test two models in a sector which in recent years has opened a wide debate on environmental sustainability. We refer to golf tourism in Andalusia, in which there has been a considerable increase in such facilities. We have used the statistical technique Partial Least Square (PLS).
