Proceso de desertificación del área altoandina del distrito de Olleros (Huaraz, Ancash)
No full textThe territory of Olleros district is considered high Andean, and extends from 3600 masl. Olleros bounded on the east by the Cordillera Blanca, so the entire territory corresponde to the western side of this, which is characterized by steep slopes over 20% of its length. Being a very rugged territory because of the steady flow of water from the numerous ravines or talwegs (in this case: Mashuan, Aco, Arzobispo, Puyhuan, Rurec and Arhuey), there can be distinguished four natural regions: Quechua, Suni, Jalca and Puna. Regions where the vegetation dominated is mainly short-stemmed and herbaceous temporary ,also with predominantly Ichu Stipa and Andean trees as Quinual (Polylepis incana) at Quebrada Rurec in inaccessible areas and high altitude (4600 m) and the Quisuar (Buddleia coreacea). The process of desertification in this part of the territory is very intense due to the practice of agricultural and livestock activities. Adding to this the geographical characteristics of the territory, there are strong surface runoff during rainy seasons, producing intense soil erosion by the sharp gradients of the terrain and low vegetation cover. The desertification process results in soil erosion and loss of capacity agrological by natural causes and human activity (manifested in the intensive land use for agriculture and livestock). Human activities practice without technology or knowledge necessary to avoid worsening the situation of the soils are some of the major causes of desertification problem affecting the population, generating low productivity of economic activities, loss of farming areas, and the consequent depopulation and population migration to cities.El territorio, considerado altoandino, del distrito de Olleros abarca a partir de 3 600 msnm. Limita por el Este con la Cordillera Blanca, por lo que la totalidad de su extensión territorial corresponde a la vertiente occidental de esta, caracterizada por fuertes pendientes (20% a más) en su gran extensión. Olleros es un territorio muy accidentado por el flujo permanente de aguas a través de los numerosos talweg o quebradas (Mashuan, Aco, Arzobispo, Puyhuan, Rurec y Arhuey) y, debido a la altitud predominante del territorio, se distinguen las regiones naturales: Quechua, Suni, Jalca y Puna. Regiones en donde predominan formaciones vegetales de tallo corto, como especies herbáceas temporales; el Stipa ichu en forma predominante y permanente; los árboles andinos, como los quinuales (polylepsis Incana) en la Quebrada Rurec, reducidos en las áreas poco accesibles y de gran altitud (4 600 msnm); y el quisuar (Budleia coreacea). El proceso de desertificación en esta parte del territorio es muy intenso debido a la práctica de actividades agrícolaganaderas. Sumando a esto las características geográficas del territorio, se producen fuertes escorrentías superficiales en épocas de lluvia, produciendo así, erosión muy intensa de suelos por las agudas pendientes del terreno y la poca cubierta vegetal. Las consecuencias del proceso de desertificación son la erosión de suelos, y la pérdida de su capacidad agrológica por causales naturales y actividad humana (que se manifiesta en el uso intensivo de la tierra con fines agrícolas y ganaderos). La práctica con conocimientos y tecnología propios que no prevén este grave problema, está afectando a la población, generando baja productividad de actividades económicas, pérdida de áreas de uso agrícola y ganadero y el consiguiente despoblamiento y migración de la población hacia las ciudades
El ordenamiento territorial instrumento de integracion, competencia y desarrollo
No full textPeru is geographically a heterogeneous contry; with uneven reliefs and very varied geoformas that determine its climatic variety, with ecosystems and an unique biodiversity in the world, In this sense, the territory\u27s ways occupation by man was given in a spontaneous and circumstantial way, generating chaos and imbalance in the national territory occupation, that\u27s for one side; for the other; for the other; the State; hasn´t advanced since the delimitations of the districts politican administrative don´t reflect the geographical reality and less the society interest´and comes generating bordering conflicts among districts, provinces and competitive and developed country and to achieve it should be opted as politics of State the territorial classification as instrumenr of physical Planning at national, regional, micro-regional and local level.El Perú es un país geográficamente DIVERSO, con relieves accidentados y geoformas muy variadas que determinan su variedad climática, con múltiples ecosistemas y ocupación del territorio por el hombre se dio de manera espontanea y circunstancial, lo que genero un caos y desequilibrio en la ocupación del territorio nacional; por otro, el Estado tampoco ha avanzado, pues las de limitaciones de las circunscripciones político-administrativas no relfejan la realidad geográfica y mucho menos los intereses de la sociedad que mas bien generan conflictos limítrofes entre distritos, provincias y departamentos, Sin embargo, esta situación puede ser superada con una visión de pais integrado, competitivo y desarrollado, y para lograrlo se debe optar como politica de Estado que el ordenamiento territorial sea un instrumento de planificación física a nivel nacional, regional, microrregional y loca
Ordenamiento y demarcacion territorial como instrumento de planificacion para el desarrollo sostenible de la region Ancash
No full textThe department of Ancash, like others departments in the country, trough history has been occupied with purposes of settlement and exploitation of its natural resources spontaneously and according to political, social, and economic national and international situation generating as consequences territorial imbalances resulting in favor of coastal strip and Callejon de Huaylas, to expenses the Andean region and the Marañon valley. This is a useful reference to make a geographic-political-administrative and socio-economic population diagnosis which confirms that the political demarcation of many districts and provinces of this department in some cases is indefinite and imprecise, what conditions and make difficult good governance creating territorial problems; where the territorial ordaining used as a planning tool, help to correct these imbalances and promotes integration based on the geographical, historical and socio-economic-cultural conditions of peoplesEl departamento de Ancash al igual que otros departamentos del país, históricamente ha sido ocupado con fines de poblamiento y aprovechamiento de sus distintos recursos naturales en forma espontánea y obedeciendo a coyunturas políticas, sociales y económicas nacionales e internacionales; que ha generado como consecuencia desequilibrios territoriales a favor de la franja costanera y del Callejón de Huaylas, en detrimento del área andina y del valle del Marañón. Lo anterior sirve como marco de referencia para hacer un diagnóstico geográficopolítico- administrativo-socioeconómico-poblacional, que confirma que la demarcación política de los distintos distritos y provincias de este departamento se encuentran indefinidos e imprecisos en algunos casos, lo que condiciona y dificulta una buena gestión, generando problemas territoriales; en donde el ordenamiento territorial como instrumento de planificación ayuda a corregir estos desequilibrios y fomenta la integración en base a las condiciones geográficas, histórico-socioeconómico-culturales de los pueblos
Ordenamiento territorial y turismo sostenible Caso: provincia Recuay-Ancash
No full textThis research because the dimension of the subject is focused to recognize and evaluate the potential of tourism, its implication on the economy and quality of life of the people and this land was used as an instrument of territorial planning to make proper use and their sustainable. The province's tourism infrastructure is scarce and precarious, despite having tangible and intangible tourism resources, whose start value would increase employment and incomes. Water potential, likely making this province to invest in productive activities. The implementation of a Land Use Plan at the provincial level of the population consult proposals regarding the capabilities and limitations of land and the sustainable use of natural resources, seeking the reduction of imbalances in the territory and ensuring the investments.La presente investigación, debido a la dimensión del tema, se enfocó al reconocimiento y evaluación del potencial turístico, su implicancia en la economía y calidad de vida de la población y para ello se utilizó el ordenamiento territorial como instrumento de planificación territorial para lograr el uso adecuado y sostenible de los mismos. La infraestructura turística de la provincia es escasa y precaria, pese a contar con recursos turísticos tangibles e intangibles, cuya puesta en valor incrementarían el empleo e ingresos de la población. Su potencial hídrico hace de esta provincia susceptible de invertir en actividades productivas. La implementación de un Plan de Ordenamiento Territorial a nivel provincial concertará propuestas de la población respecto a las potencialidades y limitaciones del territorio y al uso sostenible de los recursos naturales, buscando la reducción de los desequilibrios en el territorio y asegurando las inversiones
Identidad territorial y el turismo vivencial. Caso departamento de Ancash
No full textThe department of Ancash has 20 provinces, 166 districts and 345 rural communities which have history, traditions and culture, sheltered in its territory rich of tourist resources such as landscapes, gastronomy, patron festivities , music and dances that characterize and apart from the rest of the country and also within the region through valleys and altitudes. Tourist activity in the department is usually the sun on the beaches on the coast, recreation and culture in the Andean valleys in both the Callejón de Huaylas, as in the valley of the Marañón. Experimental tourism is now just beginning and it is practice only in some communities as Vicus, Olleros and Catac. It is shown with the return of people to their hometown accompanied with friends, motivated primarily by the festivities. This research has identified tourism resources by provinces and districts, transversed valleys in the Callejon de Huaylas, as the Rio Negro with spaces and attractive resources to the practice of experiential tourism. There has also been assessing and territorial identity by its inhabitants.El departamento de Ancash cuenta con 20 provincias, 166 distritos y 345 comunidades campesinas con historia, tradiciones y cultura propias; albergan en su territorio ricos recursos que tienen valor turístico, tales como: paisajístico, gastronómico, festividades patronales, música y danzas que le caracterizan y diferencian del resto del país y dentro de la región entre valles y pisos altitudinales. La actividad turística en el departamento es generalmente de sol en las playas en la costa, de recreación y cultura en los valles interandinos tanto en el Callejón de Huaylas como en el valle del Marañón. El turismo vivencial en la actualidad es aún incipiente por cuanto se viene dando solo en algunas comunidades como Vicus, Cátac y Olleros. Esto se ve manifestado en el retorno de las personas a su pueblo de origen en compañía de amistades, motivado principalmente por las fiestas patronales. Con esta investigación se ha logrado identificar recursos turísticos por provincias, distritos y valles transversales, como el del río Negro, en el Callejón de Huaylas con espacios y atractivos para la práctica del turismo vivencial. También se ha constatado la valoración e identidad territorial que tienen sus habitantes
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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
No full text“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
No full textWe 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
No full textWe 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
