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)

Content-based authorship identification is an emerging research problem in online social media networks, due to a wide collection of issues ranging from security to privacy preservation, from radicalization to defamation detection, and so forth. Indeed, this research has attracted a relevant amount of attention from the research community during the past years. The general problem becomes harder when we consider the additional constraint of identifying the same false profile over different social media networks, under obvious considerations. Inspired by this emerging (...) research challenge, in this paper we propose and experimentally assess an innovative framework for supporting content-based authorship identification and analysis in social media networks.

Adults (more than 18 years old) are likely to reproduce the habits that they acquired during childhood and adolescence (from 6 to 16 years old). For that reason, teachers and parents have the responsibility to promote an active and healthy lifestyle in children and adolescents. Even though every school subject should promote healthy activities, Physical Education (PE) is the most important subject to foster well-being habits associated to healthy lifestyle during sport practice and other kinds of active tasks. Indeed, there (...) are many factors that influence the acquisition of healthy habits that should be taken into account when programs and activities are implemented in both educational and extracurricular context. In this sense, psychological and social factors are of utmost importance to achieve optimal experiences for an active and healthy lifestyle. However, due to the myriad of studies analyzing different factors in different contexts, there could be confusion when programs and pedagogical strategies are applied in educational or extracurricular contexts. The objective of this investigation is to analyze the state of art of the psychosocial factors which influence the engagement in physical activities and sport practice. The keywords used in this review were mainly: ‘Self-Determination Theory’, ‘motivation’, ‘Psychological need satisfaction, ‘physical activity and sport engagement’, ‘Elementary Education’, ‘Secondary Education’, ‘Physical Education’. The articles were selected according to the following criteria: (a) peer-reviewed original research published in international journals indexed in JCR or SJR, (b) published in English or Spanish, (c) about psychosocial factors which influence the physical activity and sport engagement, (b) in educational or extracurricular context. Research articles selected were found through nine databases. It was observed that physical activities and sport practice engagement are closely related to psychological factors. In particularly, intrinsic motivation was able to determine the active participation in any activity, including physical activity and sport practice during the implementation of Small-Sided Games and other kinds of pedagogical strategies (e.g., Pedagogical Models). Motivation was also closely related to flow state. Finally, these variables should be considered in order to organize effective programs to promote an active and healthy lifestyle in Physical Education classes. (shrink)

De entre los muchos problemas con los que se encuentra la etnia gitana a la hora de convivir en sociedad, la escuela debería ser el menor. Sin embargo, las actitudes de desconocimiento, que dan lugar a reacciones xenófobas, se repiten en este contexto. El hecho de que muchos de los integrantes de la etnia gitana no consigan el Graduado Escolar, sumado a la cantidad de prejuicios a los que están sometidos, no hace sino aumentar la brecha de exclusión social de (...) esta etnia. A las y los gitanos se les culpabiliza desde todos los ámbitos, políticos, culturales y desde la propia escuela, de su no integración, de su desinterés, etc., sin atender a las diferencias sociológicas y culturales que presenta esta etnia con respecto al grupo de población mayoritaria.

Resumen Este trabajo determina algunas percepciones y usos de las redes sociales por parte del clero de la Iglesia católica española en su tarea ministerial. Partiendo de una muestra representativa se plantea un estudio cuantitativo en el que queda en evidencia que los clérigos están presentes mayoritariamente en redes cada vez menos frecuentadas por los jóvenes adolescentes, pero el uso que se hace de las mismas para acciones pastorales es limitado, cuando no insuficiente.This work determines some perceptions and uses that (...) the clergy of the Spanish Catholic Church make of social networks in their ministerial work. Based on a representative sample, a quantitative study is proposed in which it is evident that the clergy are present mainly in networks less and less frequented by young adolescents, but the use made of them for pastoral actions is limited, when not insufficient.

Analysis of the pastoral visits effected in the Diocese of Cartagena during Modern Age. With the purpose of verifying that it was what actually arrived to the parishes of the Diocese of al1 the program to conciliate proposed in Trento in 1573, the pastoral visits are analized, which were considered an important mechanism of social control. In addition, it is studied the application of the "tridentinos" decrees in the bishopric, the instructions given for the accomplishment of the pastoral visits, and (...) the conferences done to the parishes of Murcia. It concludes that, within the trentinas arrangements, the pastoral sight was a clear manifestation of the power and control in the ecclesiastic hierarchy of the parochial life in al1 its aspects, including the protagonists: the clergy and the staunch.

En la actualidad, aún se desconoce el verdadero alcance de la vasta cultura de Lope de Vega, pues, aunque se sabe que fue un gran lector, que legó más de 1500 libros, sus títulos se han perdido a lo largo de la historia. No obstante, en sus obras trasciende una serie de textos que contribuyeron a su formación. En el presente trabajo se analiza La Arcadia, considerada la novela pastoril más erudita del Siglo de Oro, desde la perspectiva de los (...) agentes terapéuticos. En esta obra se mencionan remedios de procedencia herbal, de procedencia mineral y también de procedencia animal. Los resultados confirman que Lope de Vega pudo utilizar una serie de textos científicos en sus citas sobre la materia terapéutica. Entre ellos cabe destacar a Andrés Laguna y su Dioscórides y Plinio el Viejo, cuya Historia Natural pudo haber consultado como fuente primaria, a través de alguna traducción comentada, como la de Gerónimo de Huerta o a través de alguna otra obra basada en ella, como el opúsculo de Constantino Castriota, pues, en este último caso, se encuentran párrafos muy similares y, en algunos casos, casi literales. Nowadays, the true extent of the vast culture of Lope de Vega is still largely unknown. Although it is known that he was a great reader, who bequeathed more than 1500 books, his titles have been lost throughout history. However, a series of texts that contributed to his education become known in his works. In the present paper, La Arcadia, considered the most erudite pastoral romance of Spanish Golden Age, is analyzed from the therapeutic perspective. Remedies of herbal origin, of mineral origin and also of animal origin are mentioned in this novel. The results achieved confirm that Lope de Vega was able to use a series of scientific texts in his quotations on the therapeutic subject. Among them, it is worth mentioning Andres Laguna, and Pliny the Elder, whose Natural History could have been consulted as a primary source, through some commented translation, such as that of Geronimo de Huerta, or through some other work based on it, like Constantino Castriota's opuscule. In the latter case, there are very similar and, in some cases, almost literal paragraphs. (shrink)

The spirit of the Second Vatican Council can be expressed in three terms that summarize its tremendous effort: faithful, pastoral and modern. In this spirit, the Church sought to deal with doctrinal questions in a new way, preferring mercy to severity. In agreement with this spirit of the Council, Paul VI transformed the Congregation of the Holy Office into the Congregation for the Doctrine of Faith and suppressed the Index of prohibited books. The inclusion of many modern philosophers shows that (...) the relation between modern philosophical thought and Catholic theology has been difficult, most likely due to the principle of immanence at the heart of modern thought. The article, then, analyzes and evaluates the metaphysical, gnoseological and ethical themes that stem from the assumption of the principle of immanence in some modern philosophers. However, the suppression of the Index shows that the essential continuity, faithfulness to the faith, is able to be accompanied by the accidental reform, as pastoral requirement and modernization.

Francisco Caro de Hojeda es el autor de este pequeño libro. Siguiendo las ideas predominantes en su época, presenta el orden y el significado de la oración de Memento en el rito de la Eucaristía. Se invita a los fieles a participar en la oración que el presidente de la celebración eucarística presenta a Dios en nombre de la Santa Iglesia. Se percibe un profundo sentimiento pastoral cuando se insta a los presentes a Unirse al Sacrificio así renovado.

This article addresses the challenges of dialogue with the religious pluralism. The fundamental question is: How to dialogue with the religions in Brazil and the continent? Although we know that the great religions, such as Buddhism, Hinduism, Judaism and Islam, are a minority in our reality. However, according to data presented by the various institut of research, the number of Catholics has been decreasing and increasing Pentecostals. Even, there is an increasing indifference and religious disbelief. We know that the dialogue (...) with the Pentecostal world is very challenging indeed happens only individually with some Pentecostal churches and / or pastors. (shrink)

Se percibe en el mundo académico de la teología y de la praxis pastoral, un giro general y englobante hacia el sujeto, la experiencia, la donación del amor, la misericordia, el mundo vivido de los hombres y la vivencia de la fe en la vida cotidiana de un mundo secularizado. Es un anhelo de salir de la simple conceptualización y de las discusiones sin fin sobre la fe, para dar paso a una vivencia y a una experiencia de lo creído (...) y a un testimonio que lo haga creíble. La revolución que ha propiciado el papa Francisco se fundamenta en una radicalidad del seguimiento de Jesús en la vida diaria, en las cosas sencillas, sin muchos malabares teológicos, y sí con una insistencia grande en el amor misericordioso de Dios. Este artículo quiere presentar algunas reflexiones que ayuden a fundamentar la donación experiencial del amor misericordioso, preguntándose por la experiencia, el lenguaje usado para expresarla y la libertad como respuesta del sujeto llamado en el momento del evento.

This study is concerned with the use of epistemic legitimising strategies in online newspaper articles dealing with the Scottish referendum. In this sense, we seek to explore cases of epistemic stance that indicate epistemological positioning and persuade readers of the veracity of propositions. Our study covers Scottish journal articles published online within 5 days prior to results day. In this article, we are interested in the way the Scottish newspapers deal with the topic of the independence referendum and the degree (...) of commitment in journalists’ choice of linguistic strategies. We analysed the newspaper articles manually but corpus tools were also used in order to verify initial findings and for statistical purposes. The results of the use of epistemic stance devices in the different categories were contrasted and our conclusions showed the preferred legitimising strategies used by journalists in the Scottish newspapers.

La cuestión de la justicia global en el ámbito de la bioética no es una cuestión baladí, en ella nos jugamos la dignidad a escala planetaria y la dignidad de todos y cada uno de los seres humanos en particular. El paradigma para pensar el mundo ya no es la confrontación Este-Oeste, ni incluso Norte-Sur. Los problemas, con sus posibilidades y limitaciones en la forma de abordarlos, tienen dimensiones globales. Urge una rearticulación de los discursos parcelados y compartimentados pues, desde (...) ellos, resulta extremadamente difícil seguir abordando las cuestiones que afectan a la vida descontextualizándolas del entorno global. En la misma medida tampoco se puede pensar apropiadamente la justicia sin las condiciones práctico-materiales concretas que, a nivel vital, vienen determinadas por el factum de lo global. Ni se puede abordar una ética de la vida y para la vida sin atender a referencias globales y criterios de justicia. Todo ello plantea un nuevo esquema en el que la tríada vida-globalidad-justicia ha de ser abordada también desde la Bioética Teológica. O, lo que es lo mismo, la Teología Moral no puede prescindir hoy de esa triple conexión emergente so pena de que traicione su propio estatuto de servicio. La intención de fondo en todo ello no es sino estimular la búsqueda, el diálogo y la cooperación de los bioeticistas, tanto de índole secular como teológica, en la tarea ineludiblemente humana de cuidar la fragilidad vital en todas sus dimensiones. Francisco J. Alarcos Martínez, nacido en 1963 en Cúllar (Granada), terminó los estudios de Teología en la Facultad de Teología de Granada (1986). Licenciado en Teología moral (1999) por la U. P. Comillas (Madrid), con premio extraordinario, realiza el Máster en Bioética en la misma Universidad. Se doctoró en la Facultad de Teología de Granada (2004) en la cual es profesor de Bioética y secretario de la Cátedra Andaluza de Bioética, dependiente de la misma Facultad. Además, es director del Centro de Estudios Teológico-Pastorales de Guadix (Granada) y profesor de moral en el mismo. Interviene también como profesor invitado en diversos Máster, así como en cursos monográficos sobre Bioética. Entre sus publicaciones se encuentran: Para vivir la ética en la vida pública (2000), Bioética y pastoral de la salud (2002), Co-autor de 10 palabras clave en humanizar la salud (2002), Ed. de La moral cristiana como propuesta.

Health has an important role in the achievement of a good quality of life. Many public policies intended to enhance individual and population health. Amartya Sen’s Capability Approach (CA) offers a framework to assess well-being, as well as interventions seeking to increase it. There are, however, important practical challenges that must be faced before applying CA to concrete situations, such as health. One of these challenges is defining whether it is functioning or a capability that is the feature to be (...) assessed. Moreover, some aspects of freedom that are relevant for CA are frequently neglected, such as agency. These aspects must be considered when performing a health assessment using the CA as a framework. A health assessment using the CA as a framework should include indicators based on the achieved dimension (health functioning), resources and conversion factors (health capability), and freedom to achieve (agency).

Se realizó un estudio descriptivo para evaluar la influencia de la rehabilitación protésica en la calidad de vida de los pacientes desdentados totales tratados en las clínicas estomatológicas docentes "Ismael Clark Mascaró" y "La Vigía" en Camagüey, desde septiembre del 2009 a septiembre del 2013. El universo estuvo comprendido por 254 pacientes desdentados totales rehabilitados y una muestra de 43, a través de un muestreo probabilístico aleatorio. Se obtuvo un predominio del grupo de 50-69 años y el sexo femenino. Al (...) determinar los problemas mecánicos se apreció que los flancos sobreextendidos, seguido de las inserciones frénicas sin liberar y la presencia de puntos prematuros de contacto, fueron las principales dificultades encontradas en los pacientes portadores de prótesis totales. La rehabilitación influyó en la calidad de vida de estos pacientes. It was carried out a descriptive study with the objective to evaluate the influence of prosthetic rehabilitation in total toothless patients life quality treated in the teaching stomatological clinics ¨Ismael Clark Mascaró" and "La Vigía" in Camagüey, from September 2009 to September 2013, with a universe of study composed by 254 total toothless patients who were rehabilitated. The sample was of 43, through a random probabilistic sampling. There was a predominance of the female group aged from 50-69 years old, followed by the female group aged 70. While determining the mechanical problems it was appreciated that the flanks overextended, followed of phrenic insertions without being sustained and the presence of premature points of contact, and were the main difficulties found in the patient's carrier of total prostheses. Prosthetic rehabilitation influenced in the patients´ quality life. (shrink)

In the recent literature on contextualism and relativism, one often finds disputes as to which kind of consideration would be relevant for positing a feature of a context as a parameter in the ‘‘circumstance of evaluation’: via the presence of an operator in the language which shifts that feature (Stanley) or by being a feature of a context with respect to which the truth of ‘‘propositions’’ expressed in the context is relative (McFarlane). This kind of dispute arises from two different (...) independent roles that elements in ‘‘circumstances of evaluation’’ are sometimes assumed to have. I distinguish indices from points of evaluation, and motivate its significance in the debate. (shrink)

Counterfactual definiteness is supposed to underlie the Bell theorem. An old controversy exists among those who reject the theorem implications by rejecting counterfactual definiteness and those who claim that, since it is a direct consequence of locality, it cannot be independently rejected. We propose a different approach for solving this contentious issue by realizing that counterfactual definiteness is an unnecessary and inconsistent assumption. Counterfactual definiteness is not equivalent to realism or determinism neither it follows from locality. It merely reduces to (...) an incongruent application of counterfactual reasoning. Being incompatible with falsifiability, it constitutes an unjustified assumption that goes against the scientific method rigor. Correct formulations of the Bell theorem’s bases show it is absent either as a fundamental hypothesis or as a consequence of something else. Most importantly, we present a coherent Bell inequality derivation carefully devised to show explicitly and convincingly the absence of incompatible experiments or counterfactual reasoning. Thus, even admitting that counterfactual definiteness could be a consistent assumption, the necessary conclusion is that it is irrelevant for the inequality formulation and can be safely ignored when discussing Bell’s inequality philosophical and physical implications.

Este artículo analiza la función de la imaginación moral en la enunciación de problemas morales que permitan el reconocimiento de la alteridad. El elemento transversal es la necesidad de promover la actitud fenomenológica de examinar las verdades sobre las que se erige la vida cotidiana para evitar la repetición de las violencias implícitas de lo aparentemente sobreentendido. La tesis central sostiene que la educación de la sensibilidad imaginativa establece las condiciones necesarias para permitir el florecimiento [eudaimonía] de la vida del (...) otro y en ello hay una apuesta por una ética de la otredad. El texto se estructura en tres apartados: I. La violencia subyacente en la normalidad, II. La actitud fenomenológica como acontecimiento de alteridad y III. La sensibilidad imaginativa como pauta ética. (shrink)

A common mistake present in the derivation of the usually known as the CHSH form of Bell’s inequalities is pointed out. References and comments to the correct approach are given. This error does not alter the final result and only affects the logical consistency of the derivation, but since it seems to be a widespread misconception regarding the roll and interpretation of the of use of hidden variables in Bell’s theorem it is considered to be of general interest.

Our work aimed to study the relationships between different dimensions of school climate, moral disengagement, empathy, and bullying behaviors (perpetration and victimization). The study sample consisted of 629 students (304 boys and 325 girls) aged 12–14 years (M= 12.55,SD= 0.67). Results showed how different dimensions of school climate predicted moral disengagement, empathy, and victimization, and these, in turn, predicted bullying perpetration. The results show the need to generate favorable educational environments to reduce the levels of moral disengagement and victimization and (...) to increase empathy in students as a strategy to prevent negative consequences related to bullying.
