Attention is biased towards threat-related stimuli. In three experiments, we investigated the mechanisms, processes, and time course of this processing bias. An emotional flanker task simultaneously presented affective or neutral pictures from the international affective picture system database either as central response-relevant stimuli or surrounding response-uninformative flankers. Participants’ response times to central stimuli was measured. The attentional bias was observed when stimuli were presented either for 1500 ms or 500 ms. The threat-related attentional bias held regardless of the stimuli competing (...) for attention even when presentation time was further reduced to 200 ms. The results indicate that automatic and controlled mechanisms may interact to modulate the orientation of attention to threat. The data presented here shed new light on the mechanisms, processes, and time course of this long investigated by still largely unknown processing bias. (shrink)

Este artículo presenta una reflexión sobre aquellas mujeres que siendomadres “optaron” por vincularse a las Autodefensas Unidas de Colombia, convirtiéndose la gran mayoría en “obreras de la guerra” para cumplir la función materna de no dejar morir a sus hijos. Son madres combatientesque fueron a la guerra para luchar por sus hijos/as, sacrificando su vida por ese otro que una vez hizo parte de ella. Intento demostrar que dichas madres combatientes, no transgreden las normas de la maternidad hegemónica. Transgreden sí, (...) la visión estereotipada de género, según la cual se considera a la mujer esencialmente “pacífica”. Pero no son efectivamente transgresoras de los ideales asociados a la maternidad vista fundamentalmente como esencia, como un hecho biológico e individual. Finalmente se hace una apuesta por repensar la(s) maternidad(es) en una sociedad en (pos) conflicto como la colombiana. (shrink)

La escritura académica es esencial en la formación universitaria, pero también representa un desafío, ya que los niveles de escritura no siempre son óptimos. Esta investigación describe las percepciones de los estudiantes sobre la escritura académica. Se empleó un enfoque descriptivo no experimental de tipo transversal, aplicando el Cuestionario de Percepción sobre Alfabetización Académica a 295 estudiantes en tres programas universitarios: Educación, Literatura y Lingüística, y Psicología. Los resultados reflejan una apreciación positiva de su competencia comunicativa, considerando que los conocimientos (...) adquiridos han mejorado su proceso de escritura y la identificación de diversos géneros. Al mismo tiempo, reconocen la necesidad de profundizar en las estrategias de escritura. (shrink)

ResumoNo início do século xviii, Isaac Newton publicou seu principal trabalho sobre óptica, o Opticks. Impregnado por uma perspectiva indutiva, o livro logo se tornou a principal referência para os estudos sobre a luz e as cores, sendo amplamente popularizado pelos seguidores de Newton. Neste artigo, analisamos como dois importantes livros contribuíram para essa popularização e também qual era a imagem de ciência que tencionavam propagar, o Élements de la philosophie de Newton de Voltaire e o Newtonianismo per le dame (...) de Algarotti. Será possível perceber que ambos os autores distorceram o conteúdo do livro de Newton, no intuito de propagar uma imagem idealizada das ideias newtonianas e da própria filosofia natural.In the beginning of 18th century, Newton published his main work about light and colors, the Opticks. Impregnated by an inductive perspective, the book became the major reference for the studies about light and colors, being widely popularized by Newton's followers. In this article, we analyze how two important works contributed to this process of popularization and also what image of science they intended to propagate: Voltaire's Elements of Newton's philosophie and Algarotti's Sir Isaac Newton's philosophy explain'd for the use of the ladies. We will be notice that both authors distorted the content of the Opticks, in order to propagate an idealized image of Newtonian ideas and natural philosophy itself. (shrink)

Resumen Folil Mapudungun, fruto de doce años de producción y de sistematización de objetivos y contenidos, es un método comunicativo multidimensional de enseñanza-aprendizaje de la lengua mapuche, como segunda lengua, orientado a jóvenes y adultos, en un contexto donde el mapudungun es lengua propia del territorio, lengua heredada y comunitaria. Hasta el momento, el método está integrado por ocho lecciones de estudio, desarrolladas y publicadas. En este artículo se presenta en detalle la organización de contenidos según sus tres ejes: transversal, (...) longitudinal y local. Se concluye que la concurrencia de los ejes definidos permite superar la dicotomía entre contenidos y metodología, a la vez que favorece el desarrollo de las diversas competencias que actúan en la comunicación cotidiana.Folil Mapudungun is a multidimensional method, based on a communicative approach, for teaching and learning Mapuche as a second language. It was designed for adult learners in a context where Mapudungun is a “language specific to the territory”, a heritage language and a community language. It is also the result of twelve years of research aiming to formulate objectives, and produce and systematize contents. At present, the method is constituted by eight lessons, developed and published in a textbook. This paper presents the method content organization according to three axes: transverse organization, longitudinal organization, and local organization. It is claimed that the use of these three axes allows us to overcome the methodology-content dichotomy, and to favor the development of the various communicative competences used in everyday life.

In developed countries, companies are now substantially reliant on the skills and abilities of their leaders to tackle a variety of complex issues. There is a growing consensus that leadership development training and assessment methods should adopt more holistic methodologies, including those associated with the emotional and neuroendocrine aspects of learning. Recent research into the assessment of leadership competencies has proposed the use of objective methods and measurements based on neuroscience. One of the challenges to be faced in the development (...) of a performance-based methodology to measure leadership skills is how to generate real-life situations with triggers that allow us to study management competencies under controlled laboratory conditions. A way to address this question is to take advantage of virtual environments to recreate real-life situations that might arise in performance-based assessments. We propose virtual reality (VR) as a very promising tool to observe various leadership related behavioral patterns during dynamic, complex and realistic situations. By seamlessly embedding assessment methods into virtual learning environments, VR can provide objective assessment methods with high ecological validity. VR also holds unlimited opportunities for leadership training providing subjects with intelligent tutoring systems that adapts situations in real time according to the observed behaviors. (shrink)

The De Doctrina Christiana is one of St. Augustine´s most important works, not only because of the reflection and hermeneutic exposed, but because of its special nature, since their composition realizes the vital and intellectual development of the author over two decades. A large section of the specialized reviews say that this work should be understood as a set of two irreconcilable parts, that one written in 396, with a hermeneutical character, the other finished by 426 devoted to rhetoric and (...) the doctrine of grace. While it should not be ignored the difference between these two parts of the work, it is necessary to find a common ground that not only ensures the unity of the work, but also of the whole Christian culture.

Resumen: El término “utopía” ha sido empleado por diversas corrientes e instituciones, entre ellas, la vida religiosa, para dar cuenta de ideas que movilizan sus proyectos de mundo. La pesquisa humanista y teológica en el continente latinoamericano no ha abordado de manera suficiente la relación entre utopía y vida religiosa. Esta investigación busca determinar una relación textual y contextual del uso del término utopía en las publicaciones entre 1970 y 2000 de la Conferencia de religiosos. Para ello, nos servimos de (...) las propuestas del Análisis Crítico del Discurso y la lexicografía. El análisis realizado permite establecer la dificultad y heterogeneidad de las formulaciones que expresan la utopía, sea por censura institucional o por visiones teológicas y escatológicas opuestas. A pesar de ello, los religiosos expresan una utopía latinoamericana asociada a la utopía cristiana del Reinado de Dios.: The term ‘utopia’ has been used by different tendencies and institutions, also the religious life, to show some ideas that mobilize their world projects. Latin-American theologian and humanist research hasn’t developed enough the relationship between utopia and religious life. Our research tries to determine the textual and contextual relation of the use of utopia as a term, in the “Confederación Latinoamericana de Religiosas y Religiosos” journal between 1970 and 2000. We used the tools proposed by the Critical Discourse Analysis and lexicography. The results show some difficulty and heterogeneity to formulate and express utopia. Censure and profound differences in theological and eschatological issues are some of the reasons for that matter. In spite of that, Latin-American religious life tends to express the presence of utopia associated to Christian Kingdom utopia. (shrink)

Abstract The distinction between conceptual and nonconceptual contents clearly has consequences for the configuration of the world of humans as well as for the possibility of attributing thought, in the strict sense, to systems and nonhuman organisms. With the aim of clarifying such a distinction, the following paper poses a basic notion of mental state and, especially, a clear definition of concept, along with the fundamental features of the states in which concepts occur. The conclusion of the paper is that (...) we have good and enough reasons to speak of conceptual and nonconceptual contents instead of more-or-less conceptual concepts. It means that there is a distinction of kind, not of degree, between both contents. -/- . (shrink)

Este artículo interroga críticamente la pretensión de Jacques Rancière de pensar la política sin referencia a espacios sociales ni a las relaciones de poder que tienen lugar en ellos. En este texto se pretende mostrar que estas descripciones y cartografías de los espacios sociales operan como presupuestos ocultos de la teoría rancieriana, a pesar de ser rechazadas por el mismo filósofo francés como elementos fundamentales de la reflexión sobre la política. El artículo se acerca en la primera parte a las (...) objeciones del pensador francés en contra de las teorías que derivan la naturaleza del conflicto político de la comprensión de los conflictos sociales, como el marxismo. En la segunda parte se muestra que el concepto rancieriano de la política, sin referirse a descripciones sociológicas de la sociedad como las del marxismo, caería en contradicciones internas a la hora de vincular la política con la emancipación, pues la figura de la actualización de la igualdad no basta para definir el carácter emancipatorio la irrupción política.

Childhood obesity, linked to a sedentary lifestyle and an unbalanced diet, is one of the main problems in today’s Western societies. In this sense, the aim of the study was to analyze students’ perceived satisfaction in physical education classes with learning strategies and engagement in learning and critical thinking as determinants of healthy lifestyle habits. The study involved 2,439 high school students aged 12–18 years (M= 14.66,SD= 1.78). Structural equation modeling was conducted to analyze the predictive relationships between the study (...) variables. The results showed that teaching, teaching mastery, and cognitive development are precursors to deep thinking on the part of students, indicators of the adoption of healthy lifestyle habits. These results reflect the importance of the methodology adopted by the teacher in order to positively influence the students’ habits. (shrink)

The digital transfer of the mind to a computer system requires representing the mind as a finite sequence of bits. The classic “stored-program computer” paradigm, in turn, implies the equivalence between program and data, so that the sequence of bits themselves can be interpreted as a program, which will be algorithmically executed in the receiving device. Now, according to a previous proof, on which this paper is based, a computational or algorithmic machine, however complex, cannot be free. Consequently, a finite (...) sequence of bits cannot adequately represent a free mind and, therefore, a free mind cannot be digitally transferred, quod erat demonstrandum. The impossibility of making this transfer, as demonstrated here, should be a concern especially for those who wish to achieve it. Since we intend this to be a rigorous demonstration, we must give precise definitions and conditions of validity. The most important part of the paper is devoted to explaining the meaning and reasonableness of these definitions and conditions. Special attention is paid, also, to the philosophical implications of the demonstration. Finally, this thesis is distinguished from other closely related issues. (shrink)

En el debate sobre la definición de vida algunos autores consideran que vida ha de entenderse como un género natural. Sin embargo, cuando se afirma que vida es un género natural se asumen también otras ideas vinculadas con la idea de género natural que conviene explicitar, tal y como han mostrado recientemente Bich y Green aunque de manera programática, y ese es precisamente el objetivo planteado aquí; mostrar cuáles son esas implicaciones y señalar las dificultades que surgen al adoptar el (...) discurso sobre los géneros naturales para entender y analizar categorías científicas complejas como, por ejemplo, vida. En este trabajo extendemos esta crítica a las distintas formas de entender los géneros naturales y señalamos cuál es la principal causa de las dificultades que derivan de este planteamiento. In the contemporary philosophy of biology, some authors claim that life is better undertood as a natural kind. This paper questions the metaphysical commitments related to the natural kind approach in relation with the debate of defining life. The goal of this paper is to show how considering life as a natural kind carries out some difficulties and costs. Those difficulties have been partialy shown by Bich and Green concerning the essentialist view of natural kinds. In this paper we extended this criticism to other ways of understanding natural kinds and we argue that such a difficulties are due to the acceptance of an inadequate frame of reference, based on a naïve idea of naturalness and on a natural/conventional dichotomy that is not properly justified.

El registro de la personalidad de Pablo, su formación intelectual y su misión hacen de él un hombre de controversias y de originalidades en su discurso. Este artículo pretende describir: (a) la estructura argumentativa de la llamada 'carta a Filemón' (Fm), texto considerado de autoría paulina, y (b) las maniobras estratégicas que desarrolla el autor del documento para resolver la discusión crítica, específicamente a partir del uso de estrategias de cortesía verbal. En términos generales, desde un análisis dialéctico, la carta (...) nos presenta el pedido del prisionero para que Filemón reciba a Onésimo de regreso en su casa, así como los argumentos que favorecen esta postura. Al insertar las maniobras estratégicas, es decir, el elemento pragmático y retórico, se puede observar un cambio en el punto de vista y en el argumento. Las estrategias de cortesía verbal ayudan, por un lado, a que la comunidad acoja a Onésimo y, por otro lado, aprenda que los cristianos han sido generados por la fe en Cristo. Por tanto, no sólo se declara la petición, sino una nueva verdad de fe y una práctica de vida eclesial y social. Pablo salvaguarda la imagen negativa, apelando a un nuevo estilo de autoridad y a una renovada forma de vida comunitaria que va más allá del contexto específico en el que fue escrita la carta. Todo hombre y mujer de fe son miembros dignos de la comunidad porque son “mis entrañas” (Fm 12b). (shrink)

This paper presents a novel framework for selecting socially responsible investment (SRI) portfolios. The Hedonic Price Method (HPM) is applied to obtain an evaluation of SRI criteria that is integrated into a multi-objective mathematical programming model. The HPM breaks away from the traditional view that goods are the direct object of utility; on the contrary, it assumes that utility is derived from the properties or characteristics of the goods themselves. As far as the investment decision is concerned, we assume that (...) socially responsible investmentmutual funds (SRI funds) constitute heterogeneous goods. Our approach allows us to obtain a portfolio, the financial performance of which is similar to that which the investor would have reached if he or she had not taken into account social, ethical, and environmental considerations when making his or her investment decisions. This is achieved by designing a two-stage multi-objective mathematical programming procedure. In the first stage, we achieve the maximum level of financial satisfaction that the investor can receive. In the second stage, the portfolio with the best financial–social behavior is built. For the purpose of this second stage, the first stage portfolio is used as a benchmark for the financial performance of a socially responsible portfolio. To apply this methodology, we use portfolios composed of socially responsible and conventional mutual funds domiciled in Spain. (shrink)

The current predominant conception of human rights implies that human beings have objective intrinsic value. In this paper, we defend that there is no satisfactory justification of this claim. In spite of the great variety of theories aimed at explaining objective intrinsic value, all of them share one common problematic feature: they pass from a non-evaluative proposition to an evaluative proposition by asserting that a certain entity has intrinsic value in virtue of having certain non-evaluative features. This is a step (...) that cannot be justified. In light of this negative result, we offer a radically different approach to intrinsic value. Our proposal reinterprets the claim that human beings have intrinsic value in terms of a commitment to value human beings intrinsically. This commitment provides both objective practical reasons for, and a rational explanation of, efforts aimed at defending and promoting human rights, without need to appeal to the existence of objective intrinsic value.

To analyze which ethically relevant biases have been identified by academic literature in artificial intelligence algorithms developed either for patient risk prediction and triage, or for contact tracing to deal with the COVID-19 pandemic. Additionally, to specifically investigate whether the role of social determinants of health have been considered in these AI developments or not. We conducted a scoping review of the literature, which covered publications from March 2020 to April 2021. ​Studies mentioning biases on AI algorithms developed for contact (...) tracing and medical triage or risk prediction regarding COVID-19 were included. From 1054 identified articles, 20 studies were finally included. We propose a typology of biases identified in the literature based on bias, limitations and other ethical issues in both areas of analysis. Results on health disparities and SDOH were classified into five categories: racial disparities, biased data, socio-economic disparities, unequal accessibility and workforce, and information communication. SDOH needs to be considered in the clinical context, where they still seem underestimated. Epidemiological conditions depend on geographic location, so the use of local data in studies to develop international solutions may increase some biases. Gender bias was not specifically addressed in the articles included. The main biases are related to data collection and management. Ethical problems related to privacy, consent, and lack of regulation have been identified in contact tracing while some bias-related health inequalities have been highlighted. There is a need for further research focusing on SDOH and these specific AI apps. (shrink)

(sentido y sabiduría), enfrenta este desafío siempre nuevo para la filosofía. ABSTRACT The tensions and potential links between reason and violence are a significant philosophical problem. Eric Weil's systematic work, as well as his numerous articles and lectures, is dedicated to the analysis of the historical figures of such tensions. His major work, Logique de la Philosophie, develops that objective. The article analyzes how Weil faces this always new challenge for philosophy, on the basis of the category of action -the last concrete category of his philosophy-, together with the preceding categories (absolute, unmediated particular, finite) and the formal categories (meaning and wisdom).

Based on the millenarian idea of human enhancement, the British eugenics ideology emerging at the end of the 19th century had in the North American eugenics movement the necessary support to materialize a series of racial policies with the aim of perfecting the human species. The American eugenics movement was a key step in the extension of an ideology that triumphed in many Latin American and European states, and that it lost all its scientific, political and social support because of (...) its radicalization in Germany during the Nazi Holocaust. Currently, the philosophical debate around eugenics thinking and the possibility of its return has grown exponentially due to biotechnological development, and the possibility of a human biotechnological enhancement that causes serious damage to human beings.

With the use of this technology in land registry systems, it is possible to (...) improve the transparency of the processes as well as optimize costs and execution time. To show the theoretical results of this study, the Spanish land registry has been taken as an example of a use case scenario. (shrink)

RESUMEN El pensamiento y las prácticas sociales de los atenienses de la Época Clásica se hallaban jerarquizados en favor de los varones, que se consideraban superiores naturalmente y con capacidad y derecho a gobernar en la polis y en la casa. Se muestra cómo el Agamenón de Esquilo cuestiona la naturalización de esta superioridad mediante el personaje de Clitemnestra, quien actúa, piensa y habla como varón, y muestra que matar a un familiar, cambiar de pareja, luchar por el mando se (...) justificaban si lo realizaba Agamenón. ¿Por qué se condenaban estas acciones cuando eran llevadas a cabo por Clitemnestra? ABSTRACT The thought and social practices of Athenians during the Classical period were hierarchized in favor of males, who were considered naturally superior and endowed with the capacity and right to rule the polis and the home. The article shows how Aeschylus' Agamemnon questions the naturalization of that superiority through the character of Clytemnestra, who acts, thinks, and speaks like a man, and shows that killing a family member, changing partners, and fighting for power were justified if Agamemnon did those things. Why were such actions condemned if Clytemnestra carried them out? (shrink)

Esta investigación analiza la presencia del discurso eurocéntrico en los manuales de Historia del Arte de Bachillerato desde una dimensión sociogenética. La muestra se compone de ejemplares pertenecientes a editoriales españolas de alcance nacional (Anaya, ECIR, Ediciones Ruiz, SM, Teide y Vicens Vives) en una cronología que comprende los distintos periodos por los que ha atravesado la materia entre 1953 y 2006. El estudio deriva de la aplicación de un guion de análisis documental que contempla, entre sus variables, la construcción (...) de identidades. Los resultados muestran la presencia y resistencia sociohistórica del discurso eurocéntrico en los manuales de Historia del Arte analizados, tendiéndose con ello a la construcción, reproducción y esencialización de identidades etnocéntricas. De este modo, para ahondar en la formación de una ciudadanía crítica, se hace necesario replantear los enfoques y las finalidades que fundamentan el relato de la Historia del Arte escolar en recursos como el que nos ocupa en este trabajo.

Este artículo presenta una aproximación filosófica a la literatura. Uno de los problemas ontológicos centrales de la filosofía de la literatura es intentar responder a la pregunta ¿qué es un hecho literario? o, mejor, ¿qué es y qué no es literatura? Propongo una solución institucionalista a este problema ontológico a través del desarrollo de las bases fundamentales para lo que denomino la _teoría metainstitucional de la literatura_. Expongo, en primer lugar, mi definición de la literatura como un sistema metainstitucional conformado (...) por dos metainstituciones operativamente dependientes: la _institución literaria centralizada_ y la _institución literaria marginal_. Muestro que tales metainstituciones están constituidas por _instituciones-persona_ que operan a través de actos institucionales orientados por agentes que desempeñan diversos roles (autor, lector, lectoautor, transductor o intérprete y agentes complementarios). Posteriormente, explico que las metainstituciones literarias trabajan según determinadas funciones ideológicas que constituyen la base de creencias compartidas por los agentes de sus instituciones-persona constitutivas. Tales creencias contribuyen tanto a la coordinación de las prácticas literarias como a la producción y reproducción de creencias acerca de la literatura. Finalmente, pruebo, según la teoría propuesta, que una obra adquiere el _estatus literario_, puede ser considerada una obra literaria y, por ende, distinguida de otros objetos no literarios, al superar dos instancias cruciales inherentes a las metainstituciones literarias, a saber: una instancia de _surgimiento_ y una instancia de _afirmación_.

En este trabajo proponemos mostrar que las múltiples experiencias de opresión –como efecto de las imbricaciones simultáneas entre instancias de diferenciación social y relaciones de poder- tienen como reverso experiencias de lucha, organización y resistencia colectiva como formas de participación política. Para el abordaje de las desigualdades entrecruzadas y diversas formas de violencia proponemos un enfoque interseccional por su carácter multidimensional y complejo, así como por sus raíces de lucha. Para ello, en primera instancia, trazaremos genealogías políticas que permitan historizar (...) la interseccionalidad y anudarla a sus luchas y demandas fundacionales. Analizaremos en esta dirección, las experiencias de la Combahee River Collective y de laThird World Women's Alliance, organizaciones feministas negras de la década del setenta en los Estados Unidos que buscaban enfrentar las desigualdades estructurales producidas por las articulaciones entre distintos sistemas de dominación y que direccionaron su participación política antiimperialista, anticapitalista, anticolonialista y antisexista. En un segundo momento, proponemos recuperar las genealogías críticas de la interseccionalidad para repolitizar y recomplejizar la perspectiva crítica. Finalmente, proponemos subvertir los binarismos dicotómicos y excluyentes bajo los cuales se han estructurado espacios de jerarquías y privilegios; que reproducen violencias y desigualdades.

Uno de los problemas centrales que el filósofo francés Bernard Stiegler ha abordado para sostener una constitución tecno- lógica de la humanidad, es la cuestión del origen del hombre. El asunto recae en preguntarse si es posible pensar quién es el hombre desde esta tesis, sin volver a la metafísica o la filosofía trascendental. Esta posición ha de estar enraizada en una ontología que aprehenda el componente causal a nivel relacional, dejando de lado las explicaciones en las cuales la causa (...) es substancialista. Para dar desarrollo a esta propuesta, este artículo se compone de dos partes generales: la primera está destinada a presentar hasta dónde sigue y en dónde se separa Stiegler de la concepción zoo-antropológica de André Leroi-Gourhan sobre el origen del hombre; para luego explicar las bases epistemológicas y ontológicas sobre las que Stiegler erige sus tesis tecno-ontológica de la humanidad; a saber: los fundamentos de la transducción simondoniana y la diferancia derridiana.

The purpose of this work is reviewing some reduction results to deal with systems of nonautonomous ordinary differential equations with two time scales. They could be included among the so-called approximate aggregation methods. The existence of different time scales in a system, together with some long-term features, are used to build up a simpler system governed by a lesser number of state variables. The asymptotic behavior of the latter system is then used to describe the asymptotic behaviour of the former (...) one. The reduction results are stated in two particular but important cases: periodic systems and asymptotically autonomous systems. The reduction results are illustrated with the help of simple spatial SIS epidemic models including either periodic or asymptotically autonomous terms. (shrink)

The political phenomenon that covered the period between 1958 and 1974 was known as the National Front. From the context of conceptual references related to this period, we will work on the concept of “hegemony”, which will be addressed based on Antonio Gramsci’s category. This paper aims to unravel the different political interests during a time of national unity that prevailed since the two-party system was established. Our general goal is to contribute to the discussion and analysis of our political (...) culture from a historical perspective, mostly of the student community, which, once inserted in the country’s reality, can take a stand regarding political events, thereby stopping dominance and hegemony based on National Unity agreements from becoming new totalitarian forms of “democracy”.

The balance between births and deaths in an age-structured population is strongly influenced by the spatial distribution of sub-populations. Our aim was to describe the demographic process of a fish population in an hierarchical dendritic river network, by taking into account the possible movements of individuals. We tried also to quantify the effect of river network changes (damming or channelling) on the global fish population dynamics. The Salmo trutta life pattern was taken as an example for.We proposed a model which (...) includes the demographic and the migration processes, considering migration fast compared to demography. The population was divided into three age-classes and subdivided into fifteen spatial patches, thus having 45 state variables. Both processes were described by means of constant transfer coefficients, so we were dealing with a linear system of difference equations. The discrete case of the variable aggregation method allowed the study of the system through the dominant elements of a much simpler linear system with only three global variables: the total number of individuals in each age-class.
