Executive functions (FE) are considered as a theoretical construct, referring to the capacity we have as human beings to plan, organize, inhibit, monitor our behavior and be flexible in the face of novel situations. However, this definition is not the only one, since many authors conceptualize it in different ways and this means that different models are presented that try to explain the nature of such functions; However, a consensus has not yet been reached.Therefore, the present work, brings to light those models that seek to explain executive functions in all their magnitude and complexity, finding from anatomical positions to statistical trends or to consider how they develop the FE in the stages of development, the same that were Raised in order to have a better understanding of them.

This paper highlights the need to examine the role of a constituent assembly within a democratic and constitutional system. To this end, a detailed analysis of the issue is undertaken on the basis of doctrine and constitutional history. It is concluded that the purpose of a constituent assembly is to establish a constituent power and to reform the constitution. Constituent power is the ability of a society to create or reform fundamental rights and the structure of government. Thus, the Constituent Assembly is the way in which the people exercise this power with the aim of amending the existing constitution or creating a new one. However, the author points out that there is one element that cannot be excluded by this power, and that is constitutional democracy. In this sense, this article provides a detailed study that helps to understand what a Constituent Assembly implies as a key enti...

Intelligence is a construct of notable impact in our sociocultural context, related to a wide range of conceptual and operational definitions which originate positions that highlights cognitive and abstract elements and emotional and social skills, as well was perspectives that are focused on processes underlying the intelligent performance, such as in the case of executive functions (EFs), which are configured as cognitive processes that make it possible the self-regulation (Miyake & Friedman, 2012). Similarly, there are approaches that give intelligence a relevant and predictive role of school performance, an aspect strengthened by the psychometric perspective, where the concept of intelligence has been closely linked to learning. In this line, we also find the classical perspective of crystallized Intelligence of Cattell (1943), which refers to the knowledge acquired through educa...

The article describes the psychometric analysis of the APGAR Scale developed by Smilkstein (1978), consisting of five Likert items with five alternatives, which evaluates the perception of family functioning (Gómez & Ponce, 2010). The scale was administered to 256 male students aged from 11 to 18 attending state school in Lima. Item-test correlation analysis provided evidence of highly significant relations (p<0.001) for each of the reagents, indicating that reagents evaluate indicators of the same construct. To assess the perception of family functioning, APGAR Scale has moderate internal consistency (Cronbach a = .788). Construct validity was established by factor analysis and a single factor was obtained through a principal component analysis and the orthogonal rotation (Varimax).

The rationale of this paper is to report by presenting data on the direct recognition of the canal that supplied water for over three hundred years to the city of Wari, from investigations with excavations in several sections of the channel, as a reference for qochas work, canals, reservoirs supplying the metropolis Wari (Perez 2006, 2007 and 2010) and as part of the hydrologic and hydraulic study of inca canal Wari Wari Yarccan or Yarcca in Ayacucho (Chavarría 2010). We believe that this is a great proyec for social and economic infraestructure that the Wari state executed in the Andes during the second half of the first millennium od the present Christian era, about 800 yerars before formation of the Empire of Tawantinsuyo.

Los bosques amazónicos son ecosistemas sensibles al fuego y, en consecuencia, los incendios afectan a la estructura y composición del bosque. Por ejemplo, el vestigio de los incendios pasados puede persistir a través de algunas especies y rasgos que se encuentran debido a los fuegos históricos. En este estudio se comprueban las relaciones entre los rasgos funcionales que se presentan clásicamente como los principales componentes de las estrategias ecológicas de las plantas y los filtradores ambientales relacionadas con el clima y los incendios históricos entre las parcelas de bosque maduro permanente a lo largo del rango de gradientes ambientales locales y regionales que se dan en la Amazonia. Se utilizó el porcentaje de carbono pirogénico superficial del suelo (PyC), una forma recalcitrante de carbono que puede persistir durante milenios en los suelos, como un nuevo indicador d...

The application of different unit root statistics is by now a standard practice in empirical work. Even when it is a practical issue, these statistics have complex nonstandard distributions depending on functionals of certain stochastic processes, and their derivations represent a barrier even for many theoretical econometricians. These derivations are based on rigorous and fundamental statistical tools which are not (very) well known by standard econometricians. This paper aims to fill this gap by explaining in a simple way one of these fundamental tools: namely, the Functional Central Limit Theorem. To this end, this paper analyzes the foundations and applicability of two versions of the Functional Central Limit Theorem within the framework of a unit root with a structural break. Initial attention is focused on the probabilistic structure of the time series to be considered. Thereafter...

Microbial action is one of the main causes of food decomposition, causing concern, not only in the area of public health but also in the industry, since it generates large economic losses. This is why packaging is one of the main measures or strategies used to protect products; however, the most used material for this purpose is plastic, which after fulfilling its function is discarded, becoming a serious environmental problem. Therefore, in recent years, edible packaging made from food-grade biopolymers has attracted attention because, in addition to being friendly to the environment, they also allow the incorporation of antimicrobial substances or preservatives, which help to extent the shelf life of food products. To date, nitrites and benzoates have been used as food preservatives; however, they have raised concerns due to the allergic reactions they can cause and the possible format...

Extendemos los estadísticos tipo M para una raíz unitaria analizados por Perron y Ng (1996) y Ng y Perron (2001) al caso donde se permite que el cambio en la función de tendencia ocurra en un punto desconocido. Estos estadísticos (MGLS) adoptan el enfoque GLS para eliminar la tendencia desarrollado por Elliott et al. (1996) (ERS) siguiendo los resultados de Dufour y King (1991). Siguiendo a Perron (1989), consideramos dos modelos: uno que permite un cambio en la pendiente y otro que permite tanto un cambio en el intercepto como en la pendiente. Derivamos las distribuciones asintóticas así como el estadístico óptimo factible en un punto de la hipótesis alternativa (PT GLS) sugerido por ERS. También computamos el parámetro de no centralidad utilizado por el enfoque GLS local a la unidad con el fin de eliminar la tendencia que permite que el estadístico PT GLS tenga 50% de poten...

This paper examines, including humor, the ludic function of language, which is faced dialectically with the referential function. Both are given the same importance, even though the latter is cognitively prior (Calvo 1994), so that there is no theoretical discrimination between what is purely ludic and linguistic of the joke or other styles of humor, and what is literature and the creation of worlds and characters through it. The humorous work par excellence: The Quixote is taken as an example. It is assumed at the same time that everything is humor whenever the sender and receiver agree with this, and the context is suitable: «The landlord, who, as has been mentioned, was something of a wag, and had already some suspicion of his guest’s want of wits, was quite convinced of it on hearing talk of this kind from him, and to make sport for the night he determined to fall in with his humo...
