Percepción del turista extranjero sobre la infraestructura del Aeropuerto Internacional Alejandro Velasco Astete, Cusco 2020

La siguiente investigación tuvo como lugar de estudio el Aeropuerto Internacional Alejandro Velasco Astete del Cusco del mes de febrero a julio del año 2020, con la finalidad y objetivo principal de conocer la percepción del turista extranjero sobre la infraestructura del aeropuerto en mención. Esta investigación es tipo básica, de modalidad descriptiva, de diseño no experimental y con enfoque cuantitativo. Se tuvo como muestra a 67 turistas, la técnica utilizada fue la encuesta y los resultados se procesaron utilizando el software de estadística denominado SPSS. Los resultados obtenidos fueron los siguientes: la variable percepción fue calificada como regular con un promedio de 83.6 % según la escala de medición aceptada, lo que simboliza una experiencia de carácter intermedio por parte del turista; ya que tuvo contratiempos en ciertas áreas en las instalaciones; calificaron como malo un 10.4% de los encuestados, debido a que los indicadores muestran que algunos turistas que no tuvieron una experiencia agradable durante su estadía en plataforma y de los servicios que les fueron ofrecidos hasta el embarque de su vuelo; como bueno calificaron un 6.0% de los turistas encuestados, que representaría un índice preocupante, ya que demuestra las falencias con las que cuenta el aeropuerto en distribución de espacios, señalización y calidad de instalaciones, y también en los servicios de taxi o traslado; ninguno de los encuestados califico el servicio del aeropuerto con estándares de muy bueno o muy malo, lo que refuerza la idea de percepción intermedia en general de las instalaciones del aeropuerto Alejandro Velasco Astete de Cusco. Si bien no hay instalaciones que sean percibidas como pésimas, el enfoque debe estar dirigido en reforzar las virtudes con las que, si se cuentan, que garanticen un funcionamiento óptimo para los usuarios. Los datos de la descripción de Baremación obedecen a la siguiente escala de interpretación y promedio, la calificación Muy Malo se encuentra entre 1,00 a 1,80, Malo entre 1,81 a 2,60, Regular entre 2,61 a 3,40, Bueno entre 3,40 a 4,20 y finalmente Muy Bueno entre 4,21 a 5,00 para dar conformidad a su fiabilidad.The following research was conducted at the Alejandro Velasco Astete International Airport in Cusco during the year 2020, with the purpose and main objective of knowing the foreign touristic perception about the airport infrastructure in question. This research is basic type, descriptive modality, non-experimental design and with a quantitative approach. A sample of 67 tourists was used, the technique used was the survey and the results were processed using the SPSS statistical software. The results obtained were the following: the perception variable was rated as regular with an average of 83.6% according to the accepted measurement scale, which symbolizes an intermediate experience by the tourist; since they have setbacks in certain areas on the premises; 10.4% of the respondents rated as bad, because the indicators show that some tourists did not have a pleasant experience during their stay on the platform and the services offered to them until boarding their flight; 6.0% of the tourists surveyed qualified as good, which would represent a worrying index, since it shows the shortcomings of the airport in the distribution of spaces, signage and quality of facilities, and also in taxi or transfer services; none of the respondents rated the airport service with very good or very bad standards, which reinforces the idea of general intermediate perception of the facilities of the Alejandro Velasco Astete airport in Cusco. Although there are no facilities that are perceived as lousy, the focus should be directed at reinforcing the virtues that they do have, that guarantee optimal operation for users. The data in the description of Barenacion obey the following interpretation scale and average, the Very Bad rating is between 1.00 to 1.80, Bad between 1.81 to 2.60, Regular between 2.61 to 3, 40, Good between 3.40 to 4.20 and finally Very Good between 4.21 to 5.00 to confirm its reliability

Monitoring ecological change during rapid socio-economic and political transitions: Colombian ecosystems in the post-conflict era

After more than 50-years of armed conflict, Colombia is now transitioning to a more stable social and political climate due to a series of peace agreements between the government and different armed groups. Consequences of these socio-economic and political changes on ecosystems are largely uncertain, but there is growing concern about derived increases in environmental degradation. Here, we review the capacity of Colombia to monitor the state of its ecosystems and their rate of change over time. We found several important programs currently set in place by different institutions as well as by independent groups of scientists that address different aspects of environmental monitoring. However, most of the current initiatives could be improved in terms of data coverage, quality and access, and could be better articulated among each other. We propose a set of activities that would increase the capacity of Colombia to monitor its ecosystems, provide useful information to policy makers, and facilitate scientific research. These include: 1) the establishment of a national center for ecological synthesis that focuses on analyzing existing information; 2) the establishment of an ecological observatory system that collects new information, integrates remote sensing products, and produces near real-time products on key ecological variables; and 3) the creation of new platforms for dialog and action within existing scientific and policy groups

Role of age and comorbidities in mortality of patients with infective endocarditis

Purpose: The aim of this study was to analyse the characteristics of patients with IE in three groups of age and to assess the ability of age and the Charlson Comorbidity Index (CCI) to predict mortality. Methods: Prospective cohort study of all patients with IE included in the GAMES Spanish database between 2008 and 2015. Patients were stratified into three age groups:<65 years, 65 to 80 years, and = 80 years.The area under the receiver-operating characteristic (AUROC) curve was calculated to quantify the diagnostic accuracy of the CCI to predict mortality risk. Results: A total of 3120 patients with IE (1327 < 65 years;1291 65-80 years;502 = 80 years) were enrolled.Fever and heart failure were the most common presentations of IE, with no differences among age groups.Patients =80 years who underwent surgery were significantly lower compared with other age groups (14.3%, 65 years; 20.5%, 65-79 years; 31.3%, =80 years). In-hospital mortality was lower in the <65-year group (20.3%, <65 years;30.1%, 65-79 years;34.7%, =80 years;p < 0.001) as well as 1-year mortality (3.2%, <65 years; 5.5%, 65-80 years;7.6%, =80 years; p = 0.003).Independent predictors of mortality were age = 80 years (hazard ratio [HR]:2.78;95% confidence interval [CI]:2.32–3.34), CCI = 3 (HR:1.62; 95% CI:1.39–1.88), and non-performed surgery (HR:1.64;95% CI:11.16–1.58).When the three age groups were compared, the AUROC curve for CCI was significantly larger for patients aged <65 years(p < 0.001) for both in-hospital and 1-year mortality. Conclusion: There were no differences in the clinical presentation of IE between the groups. Age = 80 years, high comorbidity (measured by CCI), and non-performance of surgery were independent predictors of mortality in patients with IE.CCI could help to identify those patients with IE and surgical indication who present a lower risk of in-hospital and 1-year mortality after surgery, especially in the <65-year group

The global abundance of tree palms

Aim Palms are an iconic, diverse and often abundant component of tropical ecosystems that provide many ecosystem services. Being monocots, tree palms are evolutionarily, morphologically and physiologically distinct from other trees, and these differences have important consequences for ecosystem services (e.g., carbon sequestration and storage) and in terms of responses to climate change. We quantified global patterns of tree palm relative abundance to help improve understanding of tropical forests and reduce uncertainty about these ecosystems under climate change. Location Tropical and subtropical moist forests. Time period Current. Major taxa studied Palms (Arecaceae). Methods We assembled a pantropical dataset of 2,548 forest plots (covering 1,191 ha) and quantified tree palm (i.e., ≥10 cm diameter at breast height) abundance relative to co‐occurring non‐palm trees. We compared the relative abundance of tree palms across biogeographical realms and tested for associations with palaeoclimate stability, current climate, edaphic conditions and metrics of forest structure. Results On average, the relative abundance of tree palms was more than five times larger between Neotropical locations and other biogeographical realms. Tree palms were absent in most locations outside the Neotropics but present in >80% of Neotropical locations. The relative abundance of tree palms was more strongly associated with local conditions (e.g., higher mean annual precipitation, lower soil fertility, shallower water table and lower plot mean wood density) than metrics of long‐term climate stability. Life‐form diversity also influenced the patterns; palm assemblages outside the Neotropics comprise many non‐tree (e.g., climbing) palms. Finally, we show that tree palms can influence estimates of above‐ground biomass, but the magnitude and direction of the effect require additional work. Conclusions Tree palms are not only quintessentially tropical, but they are also overwhelmingly Neotropical. Future work to understand the contributions of tree palms to biomass estimates and carbon cycling will be particularly crucial in Neotropical forests

Co-limitation towards lower latitudes shapes global forest diversity gradients

The latitudinal diversity gradient (LDG) is one of the most recognized global patterns of species richness exhibited across a wide range of taxa. Numerous hypotheses have been proposed in the past two centuries to explain LDG, but rigorous tests of the drivers of LDGs have been limited by a lack of high-quality global species richness data. Here we produce a high-resolution (0.025° × 0.025°) map of local tree species richness using a global forest inventory database with individual tree information and local biophysical characteristics from ~1.3 million sample plots. We then quantify drivers of local tree species richness patterns across latitudes. Generally, annual mean temperature was a dominant predictor of tree species richness, which is most consistent with the metabolic theory of biodiversity (MTB). However, MTB underestimated LDG in the tropics, where high species richness was also moderated by topographic, soil and anthropogenic factors operating at local scales. Given that local landscape variables operate synergistically with bioclimatic factors in shaping the global LDG pattern, we suggest that MTB be extended to account for co-limitation by subordinate drivers

Biodiversity recovery of Neotropical secondary forests

Old-growth tropical forests harbor an immense diversity of tree species but are rapidly being cleared, while secondary forests that regrow on abandoned agricultural lands increase in extent. We assess how tree species richness and composition recover during secondary succession across gradients in environmental conditions and anthropogenic disturbance in an unprecedented multisite analysis for the Neotropics. Secondary forests recover remarkably fast in species richness but slowly in species composition. Secondary forests take a median time of five decades to recover the species richness of old-growth forest (80% recovery after 20 years) based on rarefaction analysis. Full recovery of species composition takes centuries (only 34% recovery after 20 years). A dual strategy that maintains both old-growth forests and species-rich secondary forests is therefore crucial for biodiversity conservation in human-modified tropical landscapes.
