Valoración económica de los bienes y servicios ecosistémicos mediante la Metodología Amuvam de la cabecera de cuenca del río Chumbao, Andahuaylas, región Apurimac-2020
Get PDFLa mejor manera de demostrar y difundir la utilidad generada por los servicios y bienes
ecosistémicos ambientales a la sociedad, es a través del conocimiento de su valor económico;
es acertado admitir que la sociedad moderna es una sociedad de mercado, porque al valorar la
importancia de un activo lo toma como referencia un valor monetario. El objetivo de esta
investigación fue determinar el valor económico total mediante el Método Analítico de
Valoración Multicriterio (AMUVAM) a los bienes y servicios ecosistémicos de la cabecera de
cuenca del río Chumbao localizada en la provincia de Andahuaylas, región Apurímac. El
procedimiento del método AMUVAM consistió en agrupar las técnicas del proceso analítico
jerarquizado y la tasa de actualización de rentas. Y una vez que se aplicaron la encuesta de
comparación pareada a un panel colectivo de personas con enfoque transdisciplinar que fueron
constituidos por investigadores, Ingenieros, Funcionarios públicos, agricultores y ecologistas
que poseían un amplio conocimiento acerca del activo ambiental producidos en el ámbito
geográfico en referencia. La valorización se cuantificó hasta en tres cuantías empleando la
técnica estadística multivariante; por lo que, el grupo clúster fue conformado estadísticamente
significativo en tres conglomerados (sig<0,05). El primero: asignó una ponderación que
cuantifica a un valor económico de 4.029.902.444,41 y el tercero: un valor de menor cuantía de 4,359,179,489.46 as a high value; the second: an intermediate value of 774,163,167.16. From these valuations, it can be deduced
that on average, 51.78 % is equivalent to use value and 48.21 % to non-use value, respectively.
Although in the comparisons between subcomponents of the TEV; in general, the respondents
gave a high weight to the exitence value; meanwhile, the direct use, legacy or inheritance,
option and the indirect are values that in successive order was relegated. Thus, by quantifying
the value of the high Andean ecosystem in monetary units, a pointer of the importance of
environmentals assets is made available and perceived by apurimeños society, and it serves the
environmental authorities for decision-making and prioritizing their actionsIl miglior modo di dimostrare e diffondere l'importanza dei beni e dei servizi ecosistemici
ambientali nella società è tramite la conoscenza del suo valore economico; pertinente è
concepire che la società odierna sia una società di mercato, perché valorando l'importanza di
un attivo lo prende come riferimento un valore monetario. L'obiettivo di quest'investigazione
fu determinare il valore economico totale dei beni e servizi di ecosistema tramite il metodo
analitico di valorazione multicriterio (AMUVAM parole in inglese), dalle sorgenti del bacino
del fiume Chumbao, localizzato nella provincia di Andahuaylas, regione Apurimac. Il
procedimento del metodo AMUVAM basa sul raggruppare le tecniche del processo analitico
gerarchizzato e la tassa di aggiornamento degli affitti. E una volta applicate l'indagine
comparativa abbinata a un gruppo collettivo di persone con approccio transdisciplinare
costituiti da investigatori, ingegneri, funzionari pubblici, agricoltori e ecologisti che
possedevano grande conoscenza sull'attività ambientale prodotta nell'ambito geográfico
dall'area di studio. La valutazione è stata quantificata in un massimo di tre importi utilizzando
la tecnica statistica multivariata; Perciò, il gruppo cluster è stato formato statisticamente
significativo in tre conglomerato (sig<0.05): il primo ha assegnato una ponderazione che
quantifica un valore economico di 4.029.902.441,41 e il terzo: un valore di minore quantità di $774.163.167,16.
Da queste valorazioni ne consegue che, in media, il 51,78 % equivale al valore di utilizzo e
48,21 % al valore di non utilizzo, rispettivamente. Anche se nelle comparazioni tra i
sottocomponenti del VET, gli intervistati hanno dato un peso elevato al valore di esistenza; nel
frattempo, il valore di uso diretto, legato o ereditario, opzione e indiretto, è stato retrocesso in
ordine successivo. In questo modo, quantificando il valore dell'ecosistema altoandino in unità
monetarie, si rende disponibile un indicatore dell'importanza dei beni ambientali e che la società
di Apurima lo percepisce, e serve alle autorità ambientali per prendere decisioni e dare priorità
alla loro azioni.Este trabajo fue cofinanciado entre el Vicerrectorado de Investigación y la

Optimización de la extracción mecánica, comportamiento reológico y actividad antioxidante de hidrocoloides de hojas de Malva sylvestris”
Get PDFSe optimizaron las condiciones de extracción mecánica de hidrocoloides de hojas de Malva sylvestris y determinó el comportamiento reológico y actividad antioxidante. Las hojas fueron hidratadas en 15, 20 y 25 g de agua/g de polvo, por 30, 60 y 90 min, luego solubilizadas por expresión mediante paletas a presión de 53 db y 424, 508 y 592 mov/min por 60, 120 y 180 s. La reología en soluciones al 0,7, 1,4 y 2,1% (p/v) a 20, 30 y 40 °C se efectuó con reómetro y la actividad antioxidante a 20, 40, 60 y 80 °C se realizó cuantificando polifenoles totales y captación de radicales libres con los métodos de Folin-Ciocalteu y DPPH respectivamente. Del estudio se concluye, que para obtener rendimiento máximo en la extracción de 19,21% (p/p), las condiciones óptimas se ajustaron a modelo de segundo orden con hidratación de 25 g de agua/g de polvo por 30 min y solubilización a 592 mov/min por 180s. Los reogramas obedecieron al modelo de Ostwald, mostrando los hidrocoloides ser fluidos pseudoplásticos. Los polifenoles totales (mg AGE / 100 g muestra) de 20 a 80 °C, disminuyó de 131,17 a 78,87 y la captación de radicales libres DPPH (mM Trolox / g muestra) de 60 a 80 °C decreció de 0,422 a 0,298.Tesi
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
