Aggregation of variables allows to approximate a large scale dynamical system (the micro-system) involving many variables into a reduced system (the macro-system) described by a few number of global variables. Approximate aggregation can be performed when different time scales are involved in the dynamics of the micro-system. Perturbation methods enable to approximate the large micro-system by a macro-system going on at a slow time scale. Aggregation has been performed for systems of ordinary differential equations in which time is a continuous (...) variable. In this contribution, we extend aggregation methods to time-discrete models of population dynamics. Time discrete micro-models with two time scales are presented. We use perturbation methods to obtain a slow macro-model. The asymptotic behaviours of the micro and macro-systems are characterized by the main eigenvalues and the associated eigenvectors. We compare the asymptotic behaviours of both systems which are shown to be similar to a certain order. (shrink)

As the result of the complexity inherent in nature, mathematical models employed in ecology are often governed by a large number of variables. For instance, in the study of population dynamics we often deal with models for structured populations in which individuals are classified regarding their age, size, activity or location, and this structuring of the population leads to high dimensional systems. In many instances, the dynamics of the system is controlled by processes whose time scales are very different from (...) each other. Aggregation techniques take advantage of this situation to build a low dimensional reduced system from which behavior we can approximate the dynamics of the complex original system.In this work we extend aggregation techniques to the case of time dependent discrete population models with two time scales where both the fast and the slow processes are allowed to change at their own characteristic time scale, generalizing the results of previous studies. We propose a non-autonomous model with two time scales, construct an aggregated model and give relationship between the variables governing the original and the reduced systems. We also explore how the properties of strong and weak ergodicity, regarding the capacity of the system to forget initial conditions, of the original system can be studied in terms of the reduced system.

Two populations are subdivided into two categories of individuals (hawks and doves). Individuals fight to have access to a resource which is necessary for their survival. Conflicts occur between individuals belonging to the same population and to different populations. We investigate the long term effects of the conflicts on the stability of the community. The modelis a set of ODE's with four variables corresponding to hawk and dove individuals of the two populations. Two time scales are considered. A fast time (...) scale is used to describe frequent encounters and fightings between individuals trying to monopolize the resource. A slow time scale is used for the demography and the long term effects of encounters. We use aggregation methods in order to reduce this model into a system of two ODE's only for the total densities of the two populations which is found to be a classical Lotka-Volterra competition model. We study different cases of proportions of hawks and doves in both populations on the global coexistence and the mutal exclusion of the two populations. Pure dove tactics in both populations are unstable. In cases of mixed hawk and dove in both populations, there is coexistence. Pure dove or mixed hawk-dove tactics in one population can coexist with pure hawks in the other one when the costs of fightings between hawks are large enough. (shrink)

As a result of the complexity inherent in some natural systems, mathematical models employed in ecology are often governed by a large number of variables. For instance, in the study of population dynamics we often find multiregional models for structured populations in which individuals are classified regarding their age and their spatial location. Dealing with such structured populations leads to high dimensional models. Moreover, in many instances the dynamics of the system is controlled by processes whose time scales are very (...) different from each other. For example, in multiregional models migration is often a fast process in comparison to the growth of the population.Approximate reduction techniques take advantage of the presence of different time scales in a system to introduce approximations that allow one to transform the original system into a simpler low dimensional system. In this way, the dynamics of the original system can be approximated in terms of that of the reduced system. This work deals with the study of that approximation. In particular, we work with a non-autonomous discrete time model previously presented in the literature and obtain different bounds for the error we incur when we describe the dynamics of the original system in terms of the reduced one.

In this work we extend approximate aggregation methods in time discrete linear models to the case of time varying environments. Approximate aggregation consists in describing some features of the dynamics of a general system involving many coupled variables in terms of the dynamics of a reduced system with a few number of variables. We present a time discrete time varying model in which we distinguish two time scales. By using perturbation methods we transform the system to make the global variables (...) appear and build up the aggregated system. The asymptotic relationships between the general and aggregated systems are explored in the cases of a cyclically varying environment and a changing environment in process of stabilization. We show that under quite general conditions the knowledge of the behavior of the aggregated system characterizes that of the general system. The general method is also applied to aggregate a multiregional time dependent Leslie model showing that the aggregated model has demographic rates depending on the equilibrium proportions of individuals in the different patches.

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)

Background: In the last decades, there have been important developments in the scientific and technological areas of healthcare. On certain occasions this provokes conflict between the patients' rights and the values of healthcare professionals which brings about, within this clinical relationship, the problem of conscientious objection. Aims: To learn the opinions that the Nurses of the Madrid Autonomous Community have regarding conscientious objection. Research design: Cross-cutting descriptive study. Participants and research context: The nurses of 9 hospitals and 12 Health Centers (...) in the Madrid Autonomous Community. The study was done by means of an auto completed anonymous questionnaire. The variables studied were social-demographical and their opinions about conscientious objections. Ethical considerations: The study was approved by the Ethical Community of Clinical Research of the University Hospital Príncipe de Asturias. Participants were assured of maximum confidentiality and anonymity. Findings: A total of 421 nurses answered the questionnaire. In total, 55.6% of the nurses confirmed they were religious believers, and 64.3% declared having poor knowledge regarding conscientious objection. The matters that caused the greatest objections were voluntary abortions, genetic embryo selection, refusal of blood transfusions, and therapy refusal. Discussion: Different authors state that the most significant cases of conscientious objections for health professionals are those regarding carrying out or assisting in abortions, euthanasia, the practice of assisted reproduction and, finally, the prescription and dispensing of the morning-after pill. In our study, the most significant cases in which the nurses would declare conscientious objections would be the refusal to accept treatment, the selection of embryos after genetic diagnosis preimplantation, the patient’s refusal to receive blood transfusions due to religious reasons and pregnant women’s request for voluntary abortions within the first 14 weeks. Conclusion: Nurses’ religious beliefs influence their opinions regarding conscientious objection. The nurses who declare themselves as religious believers object in a higher percentage than those without religious beliefs. (shrink)

In this work we deal with a general class of spatially distributed periodic SIS epidemic models with two time scales. We let susceptible and infected individuals migrate between patches with periodic time dependent migration rates. The existence of two time scales in the system allows to describe certain features of the asymptotic behavior of its solutions with the help of a less dimensional, aggregated, system. We derive global reproduction numbers governing the general spatially distributed nonautonomous system through the aggregated system. (...) We apply this result when the mass action law and the frequency dependent transmission law are considered. Comparing these global reproductive numbers to their non spatially distributed counterparts yields the following: adequate periodic migration rates allow global persistence or eradication of epidemics where locally, in absence of migrations, the contrary is expected.

This study explores the relevance of corporate social responsibility (CSR) as an element of the corporate identity of Spanish financial institutions. Specifically, it aims to analyze the CSR actions developed by financial entities through the analysis of all the available information disclosed in their websites. A content analysis applied to 82 banking institutions, followed by different quantitative analyses, reveals the multidimensionality of CSR. Findings show that, while the number of entities institutionalizing CSR values as core elements of their identities is (...) still reduced, most organizations disclose CSR information to construct communicated identities and legitimate behaviours. Besides, these dimensions are classified depending on the stakeholder the action is aimed to, and that entities favour the generation of distinctive identities through the implementation and communication of more visible CSR actions like those involving their customers or the community. In any case, results indicate that organizations with certain characteristics are more likely to construct distinctive identities through CSR activities and to establish ethical and social values within their corporate statements and cultures.

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.

Las diversas tesis teóricas se sitúan en la órbita del pensamiento (...) feminista de actualidad y en donde se representarán a tres autoras: Muraro, Despentes y Braidotti. Finalmente, este dispositivo de interpretación permitirá relevar el arte de Goya a propósito de una posible revisión de crítica social sobre la virtud de la confianza. (shrink)

Current suggestions for capacities that should be targeted for moral enhancement has centered on traits like empathy, fairness or aggression. The literature, however, lacks a proper model for understanding the interplay and complexity of moral capacities, which limits the practicability of proposed interventions. In this paper, I integrate some existing knowledge on the nature of human moral behavior and present a formal model of prosocial motivation. The model provides two important results regarding the most friction-free route to moral enhancement. First, (...) we should consider decreasing self-interested motivation rather than increasing prosociality directly. Second, this should be complemented with cognitive enhancement. These suggestions are tested against existing and emerging evidence on cognitive capacity, mindfulness meditation and the effects of psychedelic drugs and are found to have sufficient grounding for further theoretical and empirical exploration. Furthermore, moral effects of the latter two are hypothesized to result from a diminished sense of self with subsequent reductions in self-interest. (shrink)

La finalidad de este artículo es explicar, mediante algunos testimonios significativos, de qué manera penetra en España el aristotelismo y cómo esta penetración del nuevo pensamiento aristotélico en Europa pone de manifiesto un permanente conflicto entre Edad Media y Renacimiento, fundamentalmente en España, donde el redescubrimiento y uso de las autoridades antiguas constituye a menudo un importante problema teórico. El autor muestra alguna de estas dificultades en varios dominios (filosofía, ciencia, literatura).

Corporations perform actions that can inflict harm with different levels of intensity, from death to material loss, to both companies’ internal and external stakeholders. Research has analysed corporate harm using the notions of corporate social irresponsibility and corporate crime. Critical management studies have been subjecting management and organizational practices and knowledge to critical analysis, and corporate harm has been one of the main concerns of CMS. However, CMS has rarely been deployed to analyse CSIR and corporate crime. Thus, the aim (...) of this paper is to critically analyse the perspectives of CSIR and corporate crimes on corporate harm via CMS in general and postcolonial studies in particular. The paper contributes by arguing that research on CSIR and corporate crime could be perceived as producing research that does not challenge the essence of contemporary corporation profit-seeking activities that ultimately produces corporate harm. We argue that CSIR and corporate crime are ideologies that assist in disguising the contradiction between producing shareholder value and the social good that is at the heart of the modern corporation system and the current economic system. Furthermore, the postcolonial view of CSIR and corporate crime highlights how they are based on a Western-centric view of corporate harm that ignores the realities and perspectives of the Global South, especially in situations where corporate harm leads to death in the Global South.

In this paper, I present an interpretation of Kant’s view that reason’s hypostasis of the idea of a sum-total of reality is dogmatic and illegitimate. In the section on the ‘Transcendental Ideal’, the second section of the Ideal of Pure Reason chapter in the Critique of Pure Reason, Kant starts by describing reason’s procedure from the affirmation of the principle of thoroughgoing determination to the hypostasis in question. According to the interpretation I defend, the argument for hypostasis deployed in this (...) section constitutes an improvement upon an argument defended by the pre-critical Kant himself in his 1673 essay “The Only Possible Argument in Support of a Demonstration of the Existence of God”. By making reference to the concept of omnitudo realitatis, the argument in the ‘Transcendental Ideal’ section presents a much more radical and convincing interpretation of the thesis that ‘possibility presupposes actuality’. Second, I present transcendental idealism and its related distinction between objects of sense and objects in general as the main dissuasive argument of the critical philosopher against hypostasis. Finally, I consider an argument against hypostasis that is independent of transcendental idealism: the threat of set-theoretical paradoxes if we hypostatize the relevant idea, intended as the concept of an absolutely comprehensive totality.

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.

El propósito fundamental del presente artículo es el de ofrecer una reconstrucción y exégesis de las reflexiones del filósofo español exiliado Juan David García Bacca en torno al problema filosófico del tiempo. En este sentido, a través de la lectura de varias de sus obras extraeremos aquellos elementos de su pensamiento que nos ofrecerán herramientas conceptuales para prefigurar las tensiones vinculadas al tratamiento de estas cuestiones por buena parte de la tradición filosófica occidental. De esta forma, partiendo del diagnóstico de (...) las aporías de la temporalidad desarrollado por Paul Ricoeur explicitaremos de qué manera la metafísica de García Bacca obliga a volver a pensar los fundamentos ontológicos del tiempo. Así, su metafísica _transustanciadora _dotará de una relevancia insoslayable a los instrumentos de medición del tiempo – en sus palabras, de _temporalización _ - en la configuración de la realidad. Ello nos permitirá rastrear desde su pensamiento una novedosa articulación de las relaciones y dependencias entre técnica y temporalidad que prefigura de forma heterodoxa la aproximación filosófica a este concepto.

Na investigação acadêmica/científica, o vago é usualmente tratado como desvio do exato. Na teoria da tradução, isso toma corpo no conceito tradicional de ‘equivalência’ como igualdade a priori e no nível do sistema linguístico. Contra essa visão, retomamos aqui uma aproximação entre o conceito de ‘normas tradutórias’ de Gideon Toury e a concepção de linguagem do Wittgen­stein tardio, orientando-nos também pelos comentários do filósofo brasileiro Arley Moreno. Defendemos que o vago tem precedência lógica ante o preciso, na linguagem tout court (...) e na tradução de modo específico. Isso se aplica particularmente aos vetores ‘adequação’ e ‘aceitabilidade’ que Toury apresenta em seu “kit do tradutor” — a partir do conceito de ‘semelhança de família’ do Wittgenstein tardio.

What did the early Greek philosophers think about animals and their lives? How did they view plants? And, ultimately, what type of relationship did they envisage between all sorts of living beings? On these topics there is evidence of a prolonged investigation by several Presocratics. However, scholarship has paid little attention to these issues and to the surprisingly "modern" development they received in Presocratics' doctrines. This book fills this lacuna through a detailed (and largely unprecedented) analysis of the extant evidence. (...) The volume includes also the first extensive collection of the ancient sources pertaining to living beings and life in early Greek philosophy, organized chronologically and thematically. (shrink)

The aim of this study was to explore the note-taking experiences of university students using paper-based and paperless resources. By means of a hermeneutic phenomenological approach, the note-taking experiences of 18 students from an international program at a university in Belgium were examined throughout a semester. In order to document these students’ practices with paper-based and paperless resources, four data collection methods were used: in-depth interviews observations focus group discussions and document analysis of students’ lecture notes. The results showed that (...) students experience note-taking as a complex phenomenon in which lived body, lived human relations, lived space and lived time come into play, and in which they try to find a balance between multiple engagements, between autonomy and authority, between attention and distraction, and between being original and mirroring others. This struggle for balance occurs irrespective of which medium they choose to use. These results provide an in-depth view of the phenomenon, and also highlight the complexity of the note-taking experience. (shrink)

We draw from Eisenstadt’s (2002) conceptualization of multiple modernities which he pro­posed to analyze processes marking modernity and their different versions in contemporary societies. These processes do not delete all pre-existing orientations, value affinities and social arrangements, and while modernity is recognizable everywhere, modern societies also differ at other respects. We formulate a similar contention for globalization. We point to three interacting and intermingling movers of social reality—globalization, multiculturalism and the national principle—which concretize everywhere, and according to contexts and a (...) priori features, specific models qualifying for the notion of multiple globalizations. Beyond the variety of multiple globalizations, this notion underlines the newness of our time and hints the “next society”. (shrink)

El renacimiento cultural del s. XII es producto de una serie de circunstancias que se pueden sintetizar en tres factores: el desarrollo económico, la expansión demográfica y el apogeo urbano. Dichas circunstancias parecen mostrar la decadencia del sistema feudal y la apertura a la sociedad moderna. Al resurgimiento literario y filosófico le acompaña el metodológico. La lógica aristotélica se convertirá en instrumento necesario tanto en los debates teológicos como jurídicos. Ya no presidida por el viejo esencialismo o la inmanencia griega, (...) se convertirá en técnica imprescindible para una sociedad que muestra una clara mentalidad ciudadana y mercantil. (shrink)

The aim of this research was to develop and validate the Questionnaire for Assessing Educational Podcasts, an instrument designed to gather students’ views about four dimensions of educational podcasts: access and use, design and structure, content adequacy, and value as an aid to learning. In study 1 we gathered validity evidence based on test content by asking a panel of experts to rate the clarity and relevance of items. Study 2 examined the psychometric properties of the QAEP, including confirmatory factor (...) analysis with cross-validation to test the factor structure of the questionnaire, as well as item and reliability analysis. The results from study 1 showed that the experts considered the items to be clearly worded and relevant in terms of their content. The results from study 2 showed a factor structure consistent with the underlying dimensions, as well as configural and metric invariance across groups. The item analysis and internal consistency for scores on each factor and for total scores were also satisfactory. The scores obtained on the QAEP provide teachers with direct student feedback and highlight those aspects that need to be enhanced in order to improve the teaching/learning process. (shrink)

Resumen: En un contexto en que la pregunta por lo humano parece divagar entre su desaparición bajo las críticas anti y post-humanistas y su reactivación justamente como respuesta a un entorno de alta incertidumbre y complejidad, la interrogante por los inicios de aquella relación entre sociología y ser humano se torna del todo importante. A partir de un análisis del núcleo fundamental de algunos de los más importantes clásicos de la sociología, se persigue a continuación desentrañar la postura original que (...) la sociología tomó con respecto a éste, así como dilucidar los motivos que la explican. En ese marco, se sostiene la tesis de que la sociología clásica habría desarrollado un intento de destierro del ser humano; un destierro que a pesar de estar afincado en su desarrollo teórico-conceptual, se ve complementado por su raigambre socio-institucional. La lectura es ya en ese entonces clara: inmersa en una incipiente lucha por reconocimiento científico, el cariz filosófico de la pregunta por lo humano se erige como un obstáculo para una cientificidad que solo puede terminar de alcanzarse a través de su exclusión.: In a context where the question about the human being seems to move between its disappearance under anti- and posthumanist critiques, and its reactivation as an answer to an environment of high uncertainty and complexity, the question about the origins of the relations between sociology and the human being becomes especially relevant. Based on a revision of the fundamental core of some of the more important classics of sociology, this article tries to reconstruct sociology’s original position regarding the human being, as well as elucidating the reasons that explain it. Within this framework, it is argued that classical sociology developed an attempt to displace the human being; a displacement that despite relying on its theoretical-conceptual development, it is complemented by its socio-institutional roots. This interpretation was already clear at that time: immersed in an incipient struggle for its scientific recognition, the philosophical tenor of the question about the human erects as an obstacle against the scientificity that can only be reached through its exclusion.

¿Apolítico? ¿Revolucionario? ¿Reaccionario? Durante largo tiempo, el pensamiento político nietzscheano ha sido sometido a múltiples alteraciones que han eclipsado su singular carga emancipadora. Pero el desafío no está tanto en la respuesta como en saber formular correctamente la pregunta, pues la dureza de la crítica nietzscheana a los movimientos sociales de su época y especialmente al socialismo no viene necesariamente acompañada de una justificación del capitalismo sino de su simultánea descalificación. Partiendo de la voluntad de poder como dinámica vital fundada (...) en la desigualdad, el presente artículo se ocupa de la relación entre Nietzsche y el socialismo, tanto de las críticas recíprocas como del sentido profundo de las mismas, justipreciando así las energías de su controvertido programa político y que lo hacen digno valedor emancipatorio en el horizonte de nuestro presente.

The use of computational tools in the humanities for science 2.0 practices is steadily increasing. This paper examines current research practices of a group of philosophers studying the history of philosophical concepts. We explain the methodology and workflow of these philosophers and provide an overview of tools they currently use in their research. The case study highlights a number of fundamental challenges facing these researchers, including: (i) accessing known relevant research content or resources; (ii) discovering new research content or data; (...) (iii) working collaboratively rather than individually. We propose a mash-up of search, visualization, and awareness tools addressing these challenges and discuss the design of the mash-up, its implementation, and evaluation with the target users. Through our case study, we demonstrate the benefits of a user-centered design approach, as well as the benefits of the concrete mash-up for historians of philosophy, and, importantly, the limitations of these tools for conducting historical and philosophical research.

Este artigo investiga alguns usos da metáfora da linguagem como cálculo em Wittgenstein. A metáfora do cálculo emerge, nos anos 30, numa interlocução com o referencialista, e é ali instrumental na recondução do olhar filosófico para os usos efetivos do simbolismo linguístico. Contudo, foi levada longe demais, ao sugerir uma imagem da linguagem composta apenas de inferências à maneira dos sistemas de regras fechados. Isto embargaria certa expansão pragmática do contexto criterial da análise conceitual. Mas a aplicabilidade do símile do (...) cálculo não é invalidada. A metáfora será reativada em manuscritos posteriores, sempre e quando puder servir aos mesmos propósitos do período intermediário, à medida que o ambiente dialógico convoque novas vozes dogmaticamente referencialistas. Ainda assim, é nos manuscritos intermediários que melhor se esclarece o seu funcionamento. Tal movimento exemplifica, por fim, um método filosófico que não procede por meio da superação de problemas à maneira científica. (shrink)

The target article criticises neural-symbolic systems as inadequate for analogical reasoning and proposes a model of analogy as transformation (i.e., learning). We accept the importance of learning, but we argue that, instead of conflicting, integrated reasoning and learning would model analogy much more adequately. In this new perspective, modern neural-symbolic systems become the natural candidates for modelling analogy.

O artigo examina os trabalhos completos de Cassirer, assim como seus escritos póstumos com relação à tese de Heinz Paetzold de que a filosofia de Cassirer sofre uma transformação em direção à antropologia em seu trabalho tardio, assim como a tese de Guido Kreis de que tal transformação da filosofia dos símbolos não é possível porque não pode garantir seu próprio fundamento. O autor demonstra uma continuidade no pensamento de Cassirer com relação ao tema da antropologia, segundo a qual Cassirer (...) vem lidando com o problema de uma metafísica do simbólico desde pelo menos 1921 e já em 1928 faz uma determinação inicial do homem como um ser capaz de forma. A retomada da questão antropológica ocorre em 1939 e está em clara continuidade com os trabalhos anteriores. A reconstrução da gênese de _Ensaio sobre o homem_ que se segue revela finalmente um segredo até então bem guardado da pesquisa de Cassirer, ou seja, uma resposta à questão de por que a história aparece pela primeira vez como uma forma simbólica na última obra publicada por Cassirer.
