La variabilité climatique et les événements extrêmes associés comme le phénomène El Niño (ENSO) représentent les épisodes les plus difficiles à gérer dans le Versant Pacifique Péruvien. En outre, une préoccupation croissante sur la disponibilité en eau a lieu depuis les années 1970s. Une documentation approfondie des régimes de précipitations et des débits est un élément clé de tout plan de gestion de l'eau et notre recherche est la première étude sur la variabilité hydroclimatique à l'échelle mensuelle et annuelle dans la zone d'étude au cours des quatre dernières décennies (période 1970-2010). Tout d'abord, un traitement de base de données exhaustif a été effectué pour surmonter certaines limitations et notamment celles liées aux conditions géographiques des Andes. Deuxièmement, le régime des précipitations a été étudié avec une approche de régionalisation liée aux conditions de séries temporelles non stationnaires. Une méthode mixte associant la méthode des clusters k-means et la méthode du vecteur régional a été proposée. Neuf régions ont été identifiées avec des régimes homogènes de précipitation tenant compte d'un gradient latitudinal et altitudinal. Un bilan hydroclimatique a ensuite été fait à l'échelle de bassin versant, abordant la problématique du climat et de l'anthropisation et leurs influences potentielles sur les séries chronologiques hydroclimatiques. Le cadre théorique de Budyko-Zhang a été utilisé et a permis d'identifier 11 des 26 bassins versants à faible influence climatique et anthropique (i.e. des conditions quasi-naturelles). Le régime des débits a ensuite été étudié pour ces conditions et une extension pour l'ensemble des 49 bassins versants de la zone d'étude a été effectuée. Un modèle hydrologique régional est proposé via deux modèles conceptuels agrégés à l'échelle de temps annuelle et mensuelle (GR1A et GR2M respectivement). Un test d'échantillonnage différentiel (DSST) a été utilisé pour améliorer la robustesse de la modélisation par rapport aux conditions climatiques contrastées entre années sèches et humides dans les conditions semi-arides. Enfin, la portée de la thèse couvre (1) une revisite de la relation ENSO/précipitation en prenant en compte les neuf régions identifiées et de plusieurs indices ENSO afin de discriminer l'influence des deux types d'El Niño (El Niño du Pacifique Est EP et du Pacifique Central CP) ainsi que l'influence de la variabilité atmosphérique (i.e. l'oscillation Madden et Julian) et aux conditions océaniques régionales. La méthodologie proposée consiste en l'analyse des composantes principales, ondelettes et de cohérence, les corrélations glissantes et l'analyse de la covariance spatiale afin de mettre en évidence la modulation décennale significative du phénomène ENSO ainsi que sa croissance à partir des années 2000s où la relation ENSO/précipitations s'inverse par rapport à la décennie précédente. Les deux modes de co-variabilité dominants entre la température superficielle de la mer dans le Pacifique tropical et les neuf régions montrent des caractéristiques dominantes de l'influence de l'ENSO: une augmentation des précipitations sur les régions aval dans le nord pendant El Niño EP et une diminution des précipitations sur les régions amont le long des Andes lors des événements El Niño CP. (2) La sensibilité au changement hydroclimatique est explorée via l'analyse des tendances hydroclimatiques comme indicateurs de changement de l'hydroclimatologie régionale. Les résultats montrent un réchauffement important dans la zone d'étude avec une moyenne de 0,2°C par décennie. En outre, les changements dans les trajectoires dans l'espace de Budyko (i.e. direction et amplitude) ont révélé que six bassins versants étaient sensibles à la variabilité du climat (i.e. probablement avec une grande sensibilité au climat futur) et aux changements d'utilisation du sol et où les précipitations et la température sont les facteurs prépondérants du changement de ces environnements. / Climate variability and associated extreme events as El Niño phenomenon (ENSO) represent the most difficult episodes to deal with along the Peruvian Pacific slope and coast. In addition, a growing water concern takes place since seventies. In-depth documentation of precipitation and runoff regimes becomes a key part in any water management plan and this research offers the first hydroclimatic variability study at monthly and annual time step in the study area over the last four decades (1970?2010 period). First, an exhaustive database treatment was carried out overcoming some limitations due to Andean geographical conditions. Second, precipitation regime was studied with a regionalization approach under non-stationary time-series conditions. A combined process consisting in k-means clustering and regional vector methodology was proposed. Nine regions were identified with a homogeneous precipitation regime following a latitudinal and altitudinal gradient. Third, a hydroclimatic balance is done at catchment-scale addressing the issue of climate and anthropogenization and their potential influences over hydroclimatic time series. The theoretical Budyko-Zhang framework was used and allowed identifying 11 out of 26 catchments with both low climate and anthropogenization influence (i.e. unimpaired conditions). This hypothesis was verified with the use of land use and land cover remote sensing products as MODIS and LBA imagery. Then, runoff regime was studied under unimpaired conditions and an extension over 49 catchments of the Peruvian Pacific drainage was done. A regional runoff model is proposed via two conceptual lumped models at annual and monthly time scale (GR1A and GR2M respectively). A Differential Split-Sample Test (DSST) was used to cope with modelling robustness over contrasted climate conditions as dry and wet years according to the semi-arid conditions. These results also showed an increasing regional discharge from arid Peruvian Pacific coast towards the Pacific Ocean. Finally, the scope of the thesis covers (1) a revisitation of ENSO/precipitation relationship considering the regionalized precipitation and several ENSO indices in order to discriminate the influence of the two types of El Niño (the eastern Pacific (EP) El Niño and the central Pacific (CP) El Niño) as well as the influence of large-scale atmospheric variability associated with the Madden and Julian Oscillation, and of regional oceanic conditions. The proposed methodology consisting in principal component analysis, wavelets and coherence, running correlations and spatial covariance analysis, highlights the significant decadal modulation with the larger ENSO impact in particular in the 2000s, ENSO/precipitation relationship reverses compared to the previous decade. The two dominant co-variability modes between sea surface temperature in the tropical Atlantic and Pacific oceans and the nine regions show salient features of the ENSO influence: increased precipitation over downstream regions in northern Peru during EP El Niño and decreased precipitation over upstream regions along the Pacific slope during CP El Niño events. (2) The sensitivity to hydroclimatic change is explored by hydroclimatic trend analysis as changes indicators of regional hydroclimatology. According to significant upward trends in annual temperature found in all catchments, results showed a significant warming in the study area with a mean of 0.2°C per decade. Also, changes in trajectories in the Budyko space (i.e. direction and magnitude) over the 11 selected catchments revealed that six catchments were shown to be sensitive to climate variability (i.e. likely with high sensitivity to future climate) and land use changes, where precipitation and temperature are the main drivers of these environments changes.

This essay presents a collection of Peruvian and other South American folk songs adapted for teaching violoncello technique with the goal of providing students with a more culturally diverse method which equally develops the left hand and right hand technique. Peruvian and other South American children learn the violoncello with European or American method books based on European folk songs. The repertoire of traditional methods usually lacks music familiar to pupils from Peruvian and other South American cultures. Written in foreign languages, the texts often exclude Spanish translation. Peruvians, especially children, are not necessarily familiar with folk music from Europe; neither are they fluent in foreign languages. Unless the teacher is familiar with the method's philosophy and is multi-lingual, a vast amount of information is lost, causing slow, and sometimes incorrect, learning. As a consequence, Peruvian music students are at a disadvantage compared to American and European music students. The core of this project consists of the collection of folk tunes arranged for violoncello and piano. The included preparatory exercises will help the student prepare for the technical challenges presented in each piece, and the original recordings of the songs' arrangements will serve as a reference for students and teachers. The purpose of this essay is not to create a new teaching philosophy, but to provide Peruvian and other South American students with a more familiar learning repertoire, drawing on the most effective methodology of three popular violoncello methods. Nonetheless, anyone interested in learning the violoncello with a multicultural repertoire can benefit from this collection.

This article analyzes gender stereotypes in the discourse of Lima’s Variedades magazine during its first stage (1908-1919), in a context of political and cultural modernization in Peru. The male and female role models promoted byVariedades were part of an inclusive discourse according to which all men and women could contribute to national progress, as long as they were willing to become «modern». The latter served to link modern values to local popular tradi- tions: while asserting the cultural superiority of the white (criollo) modernized elite, it opened possibilities for integrating the indigenous and Afro-descendant populations into national life. / El artículo analiza los estereotipos de género presentes en el discurso modernizador del proyecto editorial de la revista Variedades durante su primera etapa (1908- 1919), que coincide con una coyuntura de modernización política y cultural en el Perú. Los modelos masculinos y femeninos difundidos allí eran parte de un discurso nacionalista integrador, donde todos y todas podían aportar al progreso en la medida en que aceptaran transformarse en sujetos modernos. Dicho discurso sirvió como una bisagra que permitió conciliar los valores modernos con la tradición popular criolla, reafirmando la aparente superioridad cultural de una modernidad criolla, pero abriendo la posibilidad de integración a la vidanacional de la población indígena y afrodescendiente.

Usually, the explanations about the little electoral competitiveness of peruvian political parties have emphasized the unlikelihood that this situation could be reversed. However, when each case is analyzed carefully, we can see that groups like APRA and the Fujimorista Movement have developed some features beyond their leaders which, in certain situations, have provide them a little more electoral competitiveness than others parties, such as the Popular Christian Party (PPC). From this point, the following article argues that this difference in the competitiveness of the peruvian parties is basically for the type of strategies that they have been implemented. While some of them have seen in the permanent positioning a way to be more competitive in the medium term, others have believed that the competitiveness is achieved more quickly when political parties reduce their intervention in political debates. In that sense, this article tested an actor-center explanation to understand the little competitiveness of peruvian parties and also will risk a less pessimistic view of their future. / Las explicaciones sobre la poca competitividad electoral de los partidos políticos peruanos han enfatizando de manera predominante la improbabilidad de que ello se revierta. Sin embargo, cuando cada partido es visto con detalle se puede notar que algunos como el APRA y el Movimiento Fujimorista han desarrollado características más allá de sus líderes, los cuales en determinadas coyunturas, les han brindado una mayor competitividad electoral frente a los demás, como el Partido Popular Cristiano (PPC), por ejemplo. A partir de esta observación, el siguiente artículo argumentará que esta ligera –aunque no menos importante– diferencia en las capacidades competitivas se debe principalmente a las estrategias que han aplicado. Mientras unos han visto en el posicionamiento claro y permanente una forma de ganar competitividad en el mediano plazo, otros han creído que ello reside en la poca presencia en el debate político. Es así que, junto a una explicación voluntarista para entender la poca competitividad electoral de los partidos peruanos, se arriesgará una mirada menos pesimista sobre su futuro.

Last August marked 10 years since the start of the Camisea project, and it is undeniable the influence that it has had in Peru. However, it is also unquestionable that during the last decade, the country has suffered from critic mismanagement, called «centralism». In this context, the author gives an overview of the state of the natural gas industry in Peru. Finally, he makes reference to researches aimed at gaining access to natural gas outside the capital. / El pasado mes de agosto se cumplieron 10 años desde el inicio de operación del proyecto Camisea, y es innegable la influencia que ha tenido este proyecto en el Perú. Sin embargo, también resulta incuestionable que en esta última década el país ha padecido de una crítica mala gestión, llamada «centralismo». En este contexto, el autor hace un repaso de la situación de la industria del gas natural en el Perú. Finalmente, hace referencia a investigaciones destinadas a lograr el acceso al gas natural fuera de la capital.

The link between Administrative Law and Constitutional Law, branches of Public Law, is undeniable. It is even more patent currently with the phenomenon of the constitutionalization of Law.In this article, the author analyses this phenomenon in the field of Administrative Law, the administrative-constitutional principles, and examines how various institutions of Administrative Law have been constitutionally configurated,outlined and controlled in Peru, for which he goes over the most important jurisprudence of the Peruvian Constitutional Court regarding the matter. / La vinculación entre el Derecho Administrativo y el Derecho Constitucional, ramas del Derecho Público, es incuestionable. Ello es incluso más notorio actualmente con el fenómeno de la constitucionalización del Derecho.  En el presente artículo, el autor analiza este fenómeno en el campo del Derecho Administrativo, los principios constitucionales administrativos, y examina cómo distintas instituciones propias del Derecho Administrativo han sido configuradas, delineadas y controladas constitucionalmente en el Perú, para lo cual repasa la más importante jurisprudencia.

At every moment, persons are in contact withg oods that serve to satisfy the different needsencountered in daily life. Since the relations between persons and goods are an importantmatter, it is basic to understand the area of Civil Law that regulates them: the Rights inRem. However, we find that, from the relations that a person may establish with goods, notall of them are considered to be part of sucharea, but only a limited number.In this article, the author proposes to abandon the idea that the only Rights in Rem are the ones expressly set as them by the law, reminding that the persons themselves are the ones that can make the best decision about which relation is more  convenient for them to establish with a good, since the interest that wants to be satisfied depends on each person. / A cada momento, las personas están en contacto con bienes que sirven para satisfacerlas tantas necesidades que surgen en la vidadiaria. Siendo una materia importante la relación entre las personas y los bienes, es fundamental entender la rama del DerechoCivil que la regula: los Derechos Reales. Sin embargo, encontramos que, de las relaciones que una persona pueda establecer  con  unbien, no todas están consideradas dentro dee sta rama, sino solo un número cerrado.En el presente artículo, el autor propone abandonar la idea de que los Derechos Reales sólo son aquellos expresamente establecidos como tales por la ley, haciendo recordar que son las propias personas quienes mejor podrán decidir qué relación les conviene establecer con un bien, en vista de que el interés a satisfacer depende de cada uno.
