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)

Training for sustainable development is an educational challenge of prime importance. Physical activity and sports in natural environments provide training committed to sustainability and environmental education. The objective of this study was to assess the effects of an undergraduate training program in Physical Activities and Sports in Natural Environments concerned with sustainable development. A total of 113 students from the Autonomous University of Madrid who are studying a Bachelor’s Degree in Physical Activity and Sports Sciences and a Master’s Degree in (...) Teacher Training for Secondary Education and High School were involved. Specifically, we aimed to assess the impact of this training program on three dimensions related to Environmental Education. Its effect was also examined bearing in mind students’ sex, age and educational profile. Mixed-methods were used: for the quantitative approach, data were collected with the Environmental Attitude in Physical Activities in Natural Environments validated scale; for the qualitative approach individual reflective diaries completed by students that attended the program were analyzed. The results show positive effects on the students regarding the three dimensions of Environmental Education, for both the sportive and educational training profiles. The quantitative results do not present significant differences concerning the gender variable, although the qualitative information shows that female students perceived a greater environmental sensitivity during their practices. Regarding the age variable, significant differences are found in the youngest students with an educational profile. To conclude, the study ratifies that the program carried out generated improvements in terms of knowledge, behaviors and attitudes toward the environment and sustainable development. Future research should use larger samples and consider other variables related to education for sustainability. (shrink)

Levando–se em conta os leitores do século XXI, ao debruçar-se sobre a participação da Igreja católica brasileira na preparação do Concílio Vaticano II, o presente estudo parte de três perguntas: a) o quê interessa saber sobre a participação brasileira? b) É este um tema relevante? c) Alguns brasileiros participação significativamente na fase preparatória? Para responder apropriadamente a essas questões os autores propõem um conceito diferente de “participação” na preparação do Vaticano II por parte do episcopado brasileiro. O artigo não foca (...) apenas a presença deste ou daquele bispo ou perito nas comissões do Concílio, mas propõe a idéia de que o mais importante foi a auto-preparação, que durante certo tempo permaneceu “latente” e posteriormente se organizou através de um Concílio com um episcopado jovem, com uma média de idade em torno de 54 anos e 11 de experiência como bispo. Por isso, conscientes dos problemas pastorais que a realidade do subdesenvolvimento punha à Igreja, e com uma incipiente experiência de participação colegial, desenvolvida na construção do Plano de Emergência, este episcopado não só vivenciou em profundidade o “evento” conciliar, como foi o primeiro a sair dele organizado para colocá-lo em prática. Daqui a relevância desta reconstrução. Palavras-chave: Helder Câmara. Plano de Emergência. Colegialidade. Vaticano II. Igreja Católica no BrasilThis article aims to show the contribution of the Brazilian Catholic Church in the preparation of the Second Vatican Council. To fulfill such purpose the present study focus its research in three basic questions: a) what is important to know about the Brazilian participation? b) Is this a relevant topic? C) Some Brazilians participate significantly in the preparatory phase? To respond appropriately to these issues the authors propose a different concept of "participation" in the preparation of Vatican II by the Brazilian episcopate. The article focuses not only the presence of this or that bishop or the expert commissions of the Council, but proposes the idea that the most important was the self-preparation, which for a time remained "latent" and later was organized by a council with a young bishop, with an average age around 11 and 54 years of experience as a bishop. Therefore, aware of the problems that the pastoral reality of underdevelopment put the Church, and with an incipient experience of participating high school, developed in the construction of the Emergency Plan, the bishops not only experienced in depth the "event" to reconcile, as was the first it held out to put it into practice.

Until 1977, Monsignor Romero was a traditional Catholic bishop trained in traditional Roman theology with a penchant for order and non-involvement in 'politics'. He was also a product of the 1968 Medellin Conference which fashioned a pastoral model for the Latin American church: 'A fundamental option for the poor' on the thrust of the Second Vatican Council. This article seeks to present Oscar Romero within a historical context and proposes him as a servant-leader model for African church leaders, especially (...) Catholic bishops. (shrink)

In spite of the considerable literature nowadays existing on the issue of the moral exclusion of nonhuman animals, there is still work to be done concerning the characterization of the conceptual framework with which this question can be appraised. This paper intends to tackle this task. It starts by defining speciesism as the unjustified disadvantageous consideration or treatment of those who are not classified as belonging to a certain species. It then clarifies some common misunderstandings concerning what this means. Next, (...) it rejects the idea that there are different kinds of speciesism. Such an idea may result from confusion because there are (1) different ways in which speciesism can be defended; and (2) different speciesist positions, that is, different positions that assume speciesism among their premises. Depending on whether or not these views assume other criteria for moral consideration apart from speciesism, they can be combined or simple speciesist positions. But speciesism remains in all cases the same idea. Finally, the paper examines the concept of anthropocentrism, the disadvantageous treatment or consideration of those who are not members of the human species. This notion must be conceptually distinguished from speciesism and from misothery (aversion to nonhuman animals). Anthropocentrism is shown to be refuted because it either commits a petitio principia fallacy or it falls prey to two arguments: the argument from species overlap (widely but misleadingly known as “argument from marginal cases”) and the argument from relevance. This rebuttal identifies anthropocentrism as a speciesist view. (shrink)

Engaging and thought-provoking, this book examines how we see and treat animals and argues that we should extend equal rights to all species, human and non-human alike. Our world is plighted by 'isms' - racism, sexism and ageism to name a few - but we have one more to add: speciesism. Speciesism is a form of discrimination against those who don't belong to a certain species and it is a concept which raises controversial questions over humanity's very complicated relationship with (...) animals. Forgetting that humans are animals too, this mindset allows us to see animals as objects, rather than individuals with their own interests and with the ability to feel and suffer. This book questions all of these assumptions. Human feelings of superiority have allowed us to feel entitled to own animals as pets, to eat them, to use them for entertainment and to treat them with unkindness and cruelty. Looking at both the use of animals for the production of food, as well as the suffering of wild animals, this book advocates for society to seriously take into account the interests of all animals and argues that we have a duty to treat animals with much greater care, consideration and respect. For all who care about the rights and welfare of animals, this book is essential reading. (shrink)

Oscar Masotta (Buenos Aires, 1930- Barcelona, 1979) is all but forgotten now, except perhapsin the field of Lacanian studies. This is because in the 1970s,Masotta would challenge the master psychoanalyst on hisown turf, creating his own post-Lacanian school of psychoanalysisin Barcelona. But in 1965, aged just 27, Masottataught at the University of Buenos Aires, lectured at theDi Tella, and edited a book series on communication andmedia. A product of the newly open post-Perón era."

Dorian Gray pays a hefty price for years of sin and vice in this completely unabridged edition of The Picture of Dorian Gray.

This article tries to define what discrimination is and to understand in particular detail its most important instances: those in which the satisfaction of interests is at stake. These cases of discrimination will be characterized in terms of deprivations of benefits. In order to describe and classify them we need to consider three different factors: the benefits of which discriminatees are deprived, the criteria according to which such benefits are denied or granted, and the justification that such deprivation of benefits (...) may have (or lack). This definition intends to present discrimination as a concept that may be useful not only to examine certain social phenomena, but also, more widely, to ethical theory in general. (shrink)

Insofar as development implies economic growth, the term 'sustainable development' appears to some as a contradiction in terms. However, such conclusions still lack a thorough examination of the conceptual structure of the two terms between which there is a purported contradiction. In order to address this issue, the present paper scrutinises some of the assumptions which underwrite the ideologies of sustainability and of development. It is argued that there are key assumptions which both ideas have in common, and that sustainable (...) development is thus perfectly coherent on a conceptual level. It is alternatives which retain either term (such as 'sustainable degrowth') that are embroiled in paradox. The paper then examines two concepts for criticising the ideology of economic growth in other terms: dépense and conviviality. It is argued that the latter is preferable to the former for the purpose of developing post-sustainable critiques of growth. (shrink)

I argue that a standard formulation of hinge epistemology is host to epistemic relativism and show that two leading hinge approaches (Coliva’s acceptance account and Pritchard’s nondoxastic account) are vulnerable to a form of incommensurability that leads to relativism. Building on both accounts, I introduce a new, minimally epistemic conception of hinges that avoids epistemic relativism and rationally resolves hinge disagreements. According to my proposed account, putative cases of epistemic incommensurability are rationally resolvable: hinges are propositions that are the objects (...) of our belief-like attitudes and are rationally revisable in virtue of our overarching commitment to avoid systematic deception in our epistemic practices.

Este trabajo analiza algunas de las dimensiones fundamentales de la influencia de la obra temprana de Martin Heidegger sobre la teoría política de Hannah Arendt. Como se sabe, la pensadora judía cursó algunos de sus más cruciales años universitarios bajo la tutoría del profesor alemán. En tal sentido, tanto la perspectiva hermenéutico-fenomenológica como los conceptos de “mundo” y praxis resultaron decisivos para definir, junto con la experiencia del totalitarismo, el sentido y la profundidad de la teoría política arendtiana. En líneas (...) generales, se espera que la investigación permita no solo entender varias de las nociones centrales del pensamiento de Arendt dentro de su horizonte de sentido original, sino además visibilizar algunas de las potencialidades que la obra temprana de Heidegger posee a la hora de repensar la política y la pluralidad humana.

Reconstruction is a central notion in Dewey’s account of inquiry and in his metaphilosophical commitments. In his work, Dewey made a call for reconstruction of philosophy, in the reconstruction of central notions of the discipline, like knowledge, logic, truth, the good, reason, and experience. Inquiry itself is reconstructive, according to Dewey, involving the transformation of an indeterminate situation into one which is determinate and understood. Dewey’s philosophical views should therefore be of interest to those taking part in the recent turn (...) towards revisionary philosophical methodologies, like conceptual engineering, explication, and amelioration. In light of the recent developments in revisionary methodologies, I aim to explore Dewey’s conception of concepts in relation to the conceptual engineering literature, suggesting that it provides a useful conception of concepts for conceptual engineering, and to suggest a Deweyan model of philosophical inquiry where concepts are the objects of inquiry. In both cases, I hope to show a productive interaction between Dewey’s ideas and contemporary discussions of conceptual engineering. (shrink)

An individual's health, genetic, or environmental-exposure data, placed in an online repository, creates a valuable shared resource that can accelerate biomedical research and even open opportunities for crowd-sourcing discoveries by members of the public. But these data become “immortalized” in ways that may create lasting risk as well as benefit. Once shared on the Internet, the data are difficult or impossible to redact, and identities may be revealed by a process called data linkage, in which online data sets are matched (...) to each other. Reidentification, the process of associating an individual's name with data that were considered deidentified, poses risks such as insurance or employment discrimination, social stigma, and breach of the promises often made in informed-consent documents. At the same time, re-ID poses risks to researchers and indeed to the future of science, should re-ID end up undermining the trust and participation of potential research participants. The ethical challenges of online data sharing are heightened as so-called big data becomes an increasingly important research tool and driver of new research structures. Big data is shifting research to include large numbers of researchers and institutions as well as large numbers of participants providing diverse types of data, so the participants’ consent relationship is no longer with a person or even a research institution. In addition, consent is further transformed because big data analysis often begins with descriptive inquiry and generation of a hypothesis, and the research questions cannot be clearly defined at the outset and may be unforeseeable over the long term. In this article, we consider how expanded data sharing poses new challenges, illustrated by genomics and the transition to new models of consent. We draw on the experiences of participants in an open data platform—the Personal Genome Project—to allow study participants to contribute their voices to inform ethical consent practices and protocol reviews for big-data research.

I argue against the Standard View of ignorance, according to which ignorance is defined as equivalent to lack of knowledge, that cases of environmental epistemic luck, though entailing lack of knowledge, do not necessarily entail ignorance. In support of my argument, I contend that in cases of environmental luck an agent retains what I call epistemic access to the relevant fact by successfully exercising her epistemic agency and that ignorance and non-ignorance, contrary to what the Standard View predicts, are not (...) modal in the sense that knowledge is. After responding to objections, I conclude by sketching an alternative account of ignorance centered on the notions of epistemic access and epistemic agency. (shrink)
