Software vulnerabilities are the root cause for a multitude of security problems in computer systems. Owing to their efficiency and tight control over low-level system resources, the C and C++ programming languages are extensively used for a myriad of purposes, from implementing operating system kernels to user-space applications. However, insufficient or improper memory management frequently leads to invalid memory accesses, eventually resulting in memory corruption vulnerabilities. These vulnerabilities are used as a foothold for elaborated attacks that bypass existing defense methods. (...) In this paper, we summarise the main memory safety violation types (i.e. memory errors), and analyse how they are exploited by attackers and the main mitigation methods proposed in the research community. We further systematise the most relevant techniques with regards to memory corruption identification in current programs. (shrink)

Ideograms have great communicative value. They refer to concepts in a simple manner, easing the understanding of related ideas. Moreover, ideograms can simplify the often cumbersome notation used in the fields of Physics and physical Chemistry. Nonetheless only a few ideograms—like \ and Å—have been defined to date. In this work we propose that the scientific community follows the example of Mathematics—as well as that of oriental languages—and bestows a more important role upon ideograms. To support this thesis we propose (...) ideograms for essential concepts in Physics and Chemistry. They are designed to be intuitive, and their goal is to make equations easier to read and understand. Our symbols are included in a publicly available package. (shrink)

Desde la poesía lírica griega hasta la estética de Plotino, puede contemplarse la visión de la belleza como el objeto del amor y del deseo del Bien. Platón no alcanza una definición de lo bello en los diálogos juveniles, pero expresa de forma brillante su concepción del amor y de la belleza en el Banquete y en el Fedro. Y Plotino, interpretando estos textos platónicos, eleva el concepto de la belleza hasta la contemplación gozosa del Bien. Para él, la gracia (...) es ese don injustificado que se añade a la belleza para provocar el amor y la disponibilidad, la presencia bella que trasluce el Bien. (shrink)

This paper, looking over the life and the texts of the greek philosophers and analyzing the Pythagorean harmony, the two stories of Thales, the outstanding personality of Xenophanes, the humorous sense of Democritus and the Socratic irony, shows that philosophy in the beginning was understood not like an abstract reflection, but like a joyful search of the excellence in the human life.

This paper's aim is to study the Greek simile of the ship of state, since it was born in the Lyric Poetry until its definitive drawing by Plato's hands. It describes the image of Paros' ship, by Archilochus, or the ship of city by Alcaeus and by Theognis. Analyzes how this image improves through the tragedies of Aeschylus and Sophocles, and their moral comprehension of it. And, at last, explains the excellence achieved as the central image on Plato's politic project.

Tanto la teoría de la elección racional como diversas versiones de estructuralismo adoptan posiciones deterministas en el estudio de la sociedad de consumo. Como consecuencia, explican la relación entre identidad y consumo en términos de racionalidad abstracta o de estructuras de dominación, que niegan protagonismo a las personas concretas en los procesos de construcción identitaria. El realismo crítico relacional aporta una perspectiva de observación más atenta al papel de las personas y a su relación con su contexto sociocultural.

El objetivo del siguiente artículo es profundizar en el estudio de un movimiento pseudocientífico que tuvo lugar durante el III Reich en el campo de las matemáticas conocido como la Deutsche mathematik, tratando de concretar los factores que condicionaron el surgimiento de esta disciplina y en especial la forma en que concebía los fundamentos de las matemáticas, prestando especial atención a la relación con una de las corrientes de la filosofía de las matemáticas más importantes durante la época, el intuicionismo, (...) y su polémica con el formalismo durante principios del siglo XX.

On 20 December 1973, an attack by ETA put an end to the lives of Franco's head of government, his chauffeur and his bodyguard. This had important consequences for both the dictatorship and the terrorist group. Based on the existing sources, historians have developed a fairly credible account of the events. Nevertheless, the fact that ETA had managed to assassinate such a prominent politician, combined with some loose ends in the police investigation and the absence of a sentence gave rise (...) to all kinds of speculation. Furthermore, the case of Carrero Blanco has inspired narratives of uneven quality. In this paper we examine the interrelationship between history, conspiracy theories and fiction surrounding the attack. (shrink)

Burnout is characterized by emotional exhaustion and caused by exposure to excessive and prolonged stress related to job conditions. Moreover, burnout is highly prevalent among health care professionals. The aim of this study is, first, to examine the mediating role of social support over the effect of burnout in health care professionals and, second, to explore potential gender differences. A convenience sample of 1,035 health professionals from Ecuador, including 608 physicians and 427 nurses, was surveyed using the Maslach Burnout Inventory, (...) Social Support Survey, and General Health Questionnaire as measures of burnout, social support, and general health, respectively. Social support was found to mediate the negative effects of burnout on health regardless of gender. Differences across the three dimensions of burnout and health are further discussed, along with their implications for designing effective burnout interventions for health care professionals in Ecuador.

ABSTRACT:Ethical research on consumption has focused mainly on the obligations, principles and values guiding consumers' actions and reasons for action. In doing so, it has concerned itself mostly with such bounded contexts as voluntary simplifiers, anti-consumption movements or so-called ‘ethical consumers,’ thereby fostering an artificial opposition between ethical and non-ethical consumption. This paper proposes virtue ethics as a more apt conceptual framework for the ethical analysis of consumption because it takes into account the developmental dynamic triggered by engagement in consumption (...) practices. We build on MacIntyre's goods-virtues-practices-institutions framework and Beabout's concept of a domain-relative practice and argue that when engaging in consumption activities, agents may pursue goods internal to practices, further their individual life narratives and contribute to the good of their communities, thus developing virtues that perfect themselves both as consumers and as ethical agents.

The technical possibilities of biomedicine open up the opportunity to intervene in ageing itself with the aim of mitigating, reducing or eliminating it. However, before undertaking these changes or rejecting them outright, it is necessary to ask ourselves if what would be lost by doing so really has much value. This article will analyse the desirability of ageing from an individual point of view, without circumscribing this question to the desirability or undesirability of death. First, we will present the three (...) most widely used arguments to reject biomedical interventions against ageing. We will argue that only the last of these arguments provides a consistent answer to the question of the desirability of ageing. Second, we will show that the third argument falls prey to a conceptual confusion that we will call the paradox of ageing: although ageing entails negative health effects, it leads to a life stage with valuable goods. Both valuations, one positive and the other negative, refer to two different dimensions of ageing: the chronological and the biological. We will defend that, by not adequately distinguishing these two types of ageing, it does not become apparent that all the valuable goods exclusive to ageing derive only from its chronological dimension. Third, we will argue that, if we just conceive ageing biologically, it is undesirable. We will elaborate on the two kinds of undesirable effects biological ageing has: direct and indirect. Finally, we will respond to potential objections by adducing that these are insufficient to weaken our argument. (shrink)

This paper offers new arguments to reject the alleged dream of immortality. In order to do this, I firstly introduce an amendment to Michael Hauskeller’s approach of the “immortalist fallacy”. I argue that the conclusion “we do not want to live forever” does not follow from the premise “we do not want to die”. Next, I propose the philosophical turn from “normally” to “under these circumstances” to resolve this logical error. Then, I review strong philosophical critiques of this transhumanist purpose (...) of immortality in the literature. There are two key questions related to the possibility of fulfilling this goal: the hard problem of consciousness and the personal identity dilemma. Finally, I defend a specific type of indefinite life and justify that it is more desirable than our current limited life. (shrink)

El debate filosófico y científico sobre la extensión de la vida está polarizado entre dos visiones: una forma de prolongación débil y otra fuerte. Ambas se distinguen en función de la proximidad a la edad de Jeanne Calment o, lo que es lo mismo, a la máxima duración de la vida en la especie humana. En este artículo, evaluaré esta distinción y propondré otra alternativa para pensar en las posibilidades de prolongación de la vida. Para ello, primero revisaré cinco conceptos (...) clave en la literatura científica, ya que algunos de ellos son interpretados erróneamente por los autores que defienden esta distinción. Una distinción que adolece además de una falla importante: la incapacidad de reconocer que la duración máxima de la vida no es un número fijo de años y que no existen argumentos sólidos para garantizar que ese sea el límite de la longevidad humana. También indicaré que estos autores no captan adecuadamente el aspecto principal que nos interesa cuando tratamos de mejorar la calidad de vida a lo largo de nuestra existencia. (shrink)

Introduction: Connectedness to nature is a concept that reflects the emotional relationship between the self and the natural environment, based on the theory of biophilia, the innate predisposition to the natural environment. However, the biophobic component has largely been ignored, despite, given its adaptive functional role, being an essential part of the construct. If there is a phylogenetic component underlying nature connectedness, biophilic and/or biophobic, there should be evidence of this record from early childhood. The main aim of this study (...) is therefore to describe the emotional attributions identified in five-year-olds. Methodology: Two studies were conducted. In the first, 94 children expressed their concept of nature and made basic emotional attributions to a set of 60 images of natural and urban environments, using a software designed for the study. In the second, 39 children repeated the procedure and provided explanations for their responses. Results: The main results show that, in general, children use both positive and negative emotions, which may be related to a three-dimensional model of emotional attributions to nature. The most widely attributed emotion is happiness, for the images of both natural and built environments. However, fear is the second most common attribution. The role of happiness could be explained by a feeling of security and familiarity that the habitat of the built environment contributes to, while the importance of fear in nature could show an adaptive response of the fear of wild nature in children. This interpretation could be confirmed when analyzing specifically the emotional attributions to the natural environment, classifying the images according to biological and ecosystemic criteria. Thus, for example, more emotional attributions are explained by the "pleasantness" attributed to primary producers and landscapes (e.g. flora), versus attributions of "harm" to the images of secondary and tertiary consumers (e.g. hunters). Conclusions: These results provide evidence in favor of a didactic procedure to study emotional attributions to images of nature in preschool children. They suggest the incorporation of biophobia as an important adaptive factor in connectedness to nature and a tripartite emotional hypothesis based on the valences of the attributed emotions.

Se realizó una investigación cualitativa para comprobar la utilidad del cine como apoyo a la docencia en la asignatura de Psiquiatría del quinto año de la carrera de Medicina en tres subgrupos de estudiantes de la Universidad de Ciencias Médicas "Carlos J. Finlay" de Camagüey. La muestra ascendió a 43 estudiantes de ambos sexos y diferentes nacionalidades, a quienes se les realizaron entrevistas individuales grabadas en audio, explorando criterios personales tras haber presenciado un grupo de películas previamente escogidas por abordar (...) el tema del trastorno mental con profundidad. Las mismas se exhibieron una vez por semana, coincidiendo su tema con los objetivos propuestos según los contenidos, siempre después de la conferencia introductoria y clase taller, y antes del seminario correspondiente. Entre los resultados obtenidos se destaca que la totalidad expresó opiniones positivas respecto a la actividad, y propuso se mantuviera en el resto de las rotaciones de Psiquiatría. La totalidad consideró que la misma representó un enriquecimiento de su cultura general. La mayoría expresó que les fue fácil la identificación de síntomas, síndromes y situaciones causales en las películas utilizadas, y manifestó que existe una estrecha relación entre los contenidos semanales y las películas elegidas. Se recogieron además algunas sugerencias respecto a la actividad. Teniendo en cuenta los resultados obtenidos, se puede considerar como muy positiva la utilización del cine como apoyo a la actividad docente en Psiquiatría en el grupo estudiado. A qualitative research was carried out in three sub-groups of medical students at Carlos J. Finlay University in order to test the usefulness of films as a teaching aid for the 5th year subject of Psychiatry. The sample was composed of 43 students, both male and female, from different nationalities whose individual interviews were recorded in order to analyze personal criteria after watching a series of movies previously chosen since the plot deals with serious mental disorders. These were screened once a week. Their subject matter coincided with the objectives set according to the class content, always after the introductory lecture and workshop class, and before the corresponding seminar. The most outstanding results show that all students expressed positive views with regard to the activity, and suggested to maintain this initiative in the rest of Psychiatry rotations. All of them considered that this activity allowed them to enrich their general culture. Most expressed that it was easy for them to identify symptoms, syndromes and causal situations used in films and that there is a close relationship between the weekly contents and selected films. In addition some suggestions regarding the activity were collected. Taking into account the obtained results, the use of cinema as a teaching aid in Psychiatry can be considered as very positive in the studied group. (shrink)

Biomedical innovations are making possible the enhancement of human capabilities. There are two philosophical stances on the role that medicine should play in this respect. On the one hand, naturalism rejects every medical intervention that goes beyond preventing and treating disease. On the other hand, welfarism advocates enhancements that foster subjective well-being. We will show that both positions have considerable shortcomings. Consequently, we will introduce a third characterization in which therapies and enhancements can be reconciled with the legitimate objectives of (...) medicine inasmuch as they improve the capabilities that enable the freedom to pursue personal well-being.

ABSTRACT The aim of this interview is to show the contributions of Dan Zahavi's phenomenology to some fundamental issues in philosophy of mind. The Danish philosopher expresses his interest to link phenomenology to other disciplines and talks about his latest project, dedicated to the intersubjective relation. He also explains his position with respect to the naturalization of phenomenology, the importance of developing a philosophy of mind from a first-person perspective, and the question of Husserlian idealism and his link with Putnam. On the other hand, he refers to how the study of psychiatric disorders contributes to philosophy, presents the proposal of the pheno-menological tradition to sidestep the problems of internalism-externalism debate, and explains how his concept of self illuminates the classic discussion on mind and brain. Finally, Zahavi comments on the possibility oflinking philosophy, science and religion. (shrink)

In the philosophical debate on aging, it is common to raise the question of the theoretical definition of aging in terms of its possible characterization as a disease. Understanding aging as a disease seems to imply its medicalization, which has important practical consequences. In this paper, we analyze the question of whether aging is a disease by appealing to the concept of disease in the philosophy of medicine. As a result of this analysis, we argue that a pragmatist approach to (...) the conception of disease is the best alternative to highlight the relevance of the medicalization of aging. From this pragmatist perspective, it can be seen that the notion of aging is going through a conceptual change, and aging can today be understood as a not radically different process from any other condition that is usually considered a disease.

El tema del hombre ha sido el centro de la reflexión filosófica de los últimos siglos, siendo motivo de debate desde comienzos de la modernidad. El filósofo italiano Michele Federico Sciacca (1908-1975) tuvo conciencia clara de esto, estableciendo que la filosofía debe ser ontología y, sobre todo, ontología del hombre como existente. Esto para él significa, por lo menos, dos cosas: que el autoconocimiento es el punto de partida en el estudio filosófico y que desde el conocimiento del hombre concreto, (...) de la persona humana, podemos entender todo lo real.

We have recently stated the reasons why we claim that biological ageing is undesirable. Räsänen has responded to our article by arguing that this process has certain desirable aspects and, therefore, our position is inconsistent. Räsänen develops two arguments to defend his position. We will call the first the argument from the totality of the ageing process and the second the argument from the reduced goods of the ageing process. In this reply, we will give reasons to show that both (...) arguments fail. The first, on the one hand, starts from a dubious conception of ageing and, on the other hand, even accepting this conception, its reformulation is morally empty. The second incurs in an absurd conclusion. (shrink)

Business Ethics: A European Review, EarlyView.

The article has two aims: (a) to show how the notion of self proposed by Zahavi allows to underlie different aspects of personal identity; (b) to provide some elements that strengthen and complement the arguments of the Danish philosopher. First, I begin with a phenomenological analysis of the acts. Second, I study the identity and the various levels of the self that underlie it. Finally, I present some elements to constitute a metaphysics of the human person as a complement to (...) Zahavi’s phenomenology, considering the philosophy of mind as a framework for reflection.

El artículo tiene como objetivo presentar y valorar críticamente la propuesta de John Rogers Searle sobre la libertad. Para esto, en un primer momento mostraremos que para él la libertad debe entenderse desde la perspectiva de la primera persona, es decir desde la experiencia subjetiva. Desde allí establece que la libertad se expresa en el llamado fenómeno de la brecha, es decir, en el salto que experimentamos entre la causa y el efecto en el proceso de realización de una acción. (...) Este salto se manifiesta en los actos llevados a cabo por razones independientes del deseo, como puede observarse en el altruismo fuerte. En un segundo momento, dedicado a la valoración crítica de la propuesta de Searle, consideramos la importancia de la perspectiva de primera persona para entender la libertad. Luego mostramos que una noción analógica de causa permite entender mejor el acto libre, como así también evitar el dualismo y el reduccionismo materialista. Esta visión, propia de la tradición aristotélico-tomista y que podríamos denominar de tercera persona, debe complementarse con una reflexión desde la interioridad, como realiza Michele Federico Sciacca. Concluimos luego con una breve reflexión sobre el tema del vínculo interdisciplinar como forma de entender las temáticas antropológicas. (shrink)
