The river Portoviejo crosses four cantons of the province of Manabí and is the main source of water for the inhabitants of the area to be used in various uses. The objective of this bibliographic review article is to carry out a historical analysis of the water pollution of the Portoviejo River. The qualitative and descriptive documentary research methodology was used. The authors conclude that the factors that influence the pollution of the Portoviejo River are the constant direct discharges of (...) wastewater and solid waste along its route by the residents of the area and the contribution of the water treatment plant waste from the area.

El objetivo de la formación doctoral es la generación y difusión de nuevo conocimiento, sin embargo, no es claro cómo los programas de doctorado en Colombia se relacionan con este tipo de producción académica. A partir de ello, en el presente estudio se presenta el panorama general de la producción académica a través de las instituciones de educación superior colombianas que ofertan programas de formación doctoral en psicología. La producción académica se obtuvo de la base de datos Scopus en una (...) muestra de 13 universidades. Tras una búsqueda inicial, se encontraron 1345 documentos, con los cuales se realizó un análisis de los indicadores de productividad y de las redes de colaboración al interior de la disciplina en el país. Posteriormente, esta información se contrastó con la información nacional registrada en el sistema de Currículum Vitae Latinoamericano y del Caribe de 193 profesores asociados a las universidades que ofertan los programas de doctorado. Al comparar la producción académica nacional e internacional, se encontró una mayor correlación entre la dirección de tesis de posgrado y la publicación en revistas nacionales. Por lo tanto, se puede afirmar que el impacto de la formación doctoral en la generación de nuevo conocimiento es relativo y tiene un alcance limitado, siendo principalmente las revistas nacionales el medio de difusión de este conocimiento. Se recomienda evaluar el impacto de los productos asociados a la formación posgradual y la visibilidad internacional, con énfasis en las revistas indexadas en bases de datos internacionales.

El presente artículo aborda la reconstrucción de los conflictos que enfrentaron a la burguesía agraria argentina con el gobierno nacional encabezado por Cristina Fernández de Kirchner, entre marzo y julio de 2008. Estos enfrentamientos interburgueses son comparados con su antecesor inmediato, los “paros agrarios” de 1975, con los que las corporaciones rurales iniciaron una ofensiva destinada a impulsar el golpe de estado de marzo de 1976, cuyo programa consistía en eliminar la amenaza revolucionaria y relanzar la acumulación de capital. (...) Nos ocuparemos de reconstruir las alianzas sociales enfrentadas en ambas coyunturas, sus componentes, su programa y sus acciones, prestando especial atención a la acción política emprendida por la burguesía agraria. Buscamos desentrañar, de esta manera, la naturaleza de ambas crisis, sus semejanzas y diferencias. (shrink)

El pensamiento politico medieval concibe a la ley como esencialmente ligada a un concepto de justicia superior y objetivo. El trabajo procura zanjar las divergencias en tomo del concepto ley en Marsilio de Padua. Para ella, se efectua un analisis de la ecuacion entre las facultades cognoscitivas y volitivas que aparecen en el tratamiento del fin de la ley, de las cualidades personales requeridas para el juez, y de la idoneidad dellegislador humano. La ley debe poseer un contenido de justicia (...) que es objeto de una captacion racional y de un recto querer. Sin embargo, ese concepto de justicia adquiere en Marsilio una definicion estrictamente politica: se trata del "equilibria" o la "medida" que deben alcanzar los actos transitivos de los hombres, can el fin de preservar la comunidad politica.

Nos últimos anos, cada vez mais os "ismos" estão sendo deixados de lado. Neste sentido, quando se fala de aristotelismo ou de averroísmo de Marsílio de Pádua, torna-se necessário examinar o que se entende precisamente por tais atributos e, depois, até que ponto, mesmo de forma aproximativa, eles podem ser aplicados a Marsílio.

This paper explores the ethical dilemma of conflicting loyalties found in whistleblowing. Central to this dilemma is the internal/external disclosure dichotomy; disclosure of organisational wrongdoing to an external recipient is seen as disloyal, whilst disclosure to an internal recipient is seen as loyal. Understanding how the organisation and society have dealt with these problems over the last 30 years is undertaken through an analysis of Vandekerckhove’s project, which seeks to place the normative legitimisations of whistleblowing legislation and organisational whistleblowing policies (...) within a globalisation semantic able to contain this conflict between society and the organisation. This project fails, it is argued, because of Vandekerckhove’s particular understanding of the organisation as an autopoietic system, i.e. an operationally closed system. A case is made to understand organisations as complex systems, i.e. operationally open systems. Critical Complexity theory sees the identities of systems and components as coterminous. In the context of the organisation, this means that the identities of the corporation and its corporate members arise and die together. The whistleblower’s disclosure reconfigures the organisation by forcing the organisation to open up and make its boundaries flexible, making the designation ‘internal’ or ‘external’ to the organisation, and, therefore, who qualifies as a recipient of a disclosure of wrongdoing, flexible. The organisation is restrained from retailing against the whistleblower, because its identities are coterminous. Furthermore, as the disclosure cannot be categorically defined as either internal or external, the question of whether an external disclosure can qualify as an act of organisational loyalty becomes moot.

A novel thermodynamic perspective on natural selection is presented. In the case that life continuity is optimized in an ideal system, where relatively constant and homogeneous selective pressures favour a given competing species, natural selection leads that system to a stationary state of maximum genotypic uniformity of life and maximum sustainable consumption of available energy by life (competitive equilibrium). Structurally and functionally, this optimizing tendency towards competitive equilibrium looks similar to the optimizing tendency towards thermodynamic equilibrium of classical thermodynamics (maximum (...) energetic uniformity and maximum degradation of available energy). The principle of competitive exclusion may thus be conceptually viewed as an ecological manifestation of the second law of (classical) thermodynamics. On the other hand, the novel thermodynamic perspective on natural selection is discussed with regard to the open and nonequilibrium system of nature, where selective pressures vary in space and time. In this case, natural selection can induce diversity instead of uniformity, though an optimizing tendendcy towards maximum sustainable consumption of resources (optimization of life continuity) always remains. Overall, it is concluded that the action of natural selection favours the maximization of the sustainable consumption of energy at the level of individual organism. (shrink)

My starting point in this article is that investigating the ethics of autonomous vehicles through the lens of the trolley problem is not only limited but also unethical. I construct my case by aligning myself with Niklas Toivakainen, who argues against David Gunkel’s reading of Levinasian ethics as an answer to the “Machine Question”. I adumbrate Toivakainen’s critique that the attempt to give a Levinasian face to the machine is an example of a compensatory logic – a way to avoid (...) a deeper exploration of the moral dynamics from which our technologies emerge. I offer an extended reading of Levinas’s formulation of the face of the other to argue that while the machine cannot signify as a face, the machine can announce or anticipate the signification of the face which the self is infinitely responsible to. I reach this conclusion through focusing on the uncertainty and ambiguity of the signification of the face. I then argue that current approaches to the ethics of autonomous vehicles, based on variations of the trolley problem, fail to locate ethical responsibility to the other, precisely in its attempts to evade uncertainty. I demonstrate how an embrace of uncertainty can make the ethics of autonomous vehicles more ethical through a consideration of the concept of shared space and naked streets in the work of the late Dutch traffic engineer Hans Monderman.

The Shannon information function (H) has been extensively used in ecology as a statistic of species diversity. Yet, the use of Shannon diversity index has also been criticized, mainly because of its ambiguous ecological interpretation and because of its relatively great sensitivity to the relative abundances of species in the community. In my opinion, the major shortcoming of the traditional perspective (on the possible relation of species diversity with information theory) is that species need for an external receiver (the scientist (...) or ecologist) to exist and transmit information. Because organisms are self-catalized replicating structures that can transmit genotypic information to offspring, it should be evident that any single species has two possible states or alternatives: to be or not to be. In other words, species have no need for an external receiver since they are their own receivers. Therefore, the amount of biological information (at the species scale) in a community with one only species would be species, and not bits as in the traditional perspective. Moreover, species diversity appears to be a monotonic increasing function of (or S) when all species are equally probable (S being species richness), and not a function of as in the traditional perspective. To avoid the noted shortcoming, we could use 2H (instead of H) for calculating species diversity and species evenness (= 2H/S). However, owing to the relatively great sensitivity of H to the relative abundances of species in the community, the value of species dominance (= 1 − 2H/S) is unreasonably high when differences between dominant and subordinate species are considerable, thereby lowering the value of species evenness and diversity. This unsatisfactory behaviour is even more evident for Simpson index and related algorithms. I propose the use of other statistics for a better analysis of community structure, their relationship being: species evenness + species dominance = 1; species diversity × species uniformity = 1; and species diversity = species richness × species evenness.

El trabajo se ocupa de la concepción acerca de la función y los límites de la enseñanza en el diálogo De magistro de Agustín de Hipona y en la undécima de las Cuestiones disputadas sobre la verdad de Tomás de Aquino. Explorando los límites del lenguaje y de la comunicación, Agustín concluye que el maestro propiamente no enseña, a lo sumo, advierte al discípulo para que pueda reconocer la verdad iluminado por el Maestro Interior. Para Aquino, el maestro propiamente puede (...) enseñar, pero con ello no hace más que asistir al discípulo para que efectúe con su razón el mismo recorrido que hace la razón humana al derivar las conclusiones de la ciencia a partir de los principios del conocimiento humano. A pesar de sus diferencias, ambos coinciden en que la enseñanza es cualquier cosa menos una “transferencia del saber”. (shrink)

O presente artigo trata do caráter contingente ou necessário da relação causal entre a causa primeira e seu efeito, tal como apresentada por Avicena e Tomás de Aquino. Para tanto, aborda o paralelismo no tratamento da inteligência e vontade divinas por parte de ambos os autores. Ambos aceitam que Deus conhece a si mesmo e, conhecendo-se, conhece aquilo que lhe é distinto. Aceitam igualmente que Deus quer ou ama a si mesmo e, querendo a si mesmo, quer acidentalmente o que (...) lhe é distinto. No entanto, discordam com respeito à necessidade ou contingência do mundo. Para Avicena, o mundo é possível em si mesmo, mas “necessário por outro”. Para Tomás, que Deus queira o mundo com necessidade hipotética corresponde mais à necessidade do querer divino, sem que isso determine a contingência ou necessidade do mundo. Com efeito, na visão tomista, é preferível um universo no qual haja mescla de necessidade e contingência, pois isso representa melhor as múltiplas perfeições divinas. (shrink)

El trabajo se ocupa de la sección de las Glosas a la Isagogé de Porfirio de Pedro Abelardo dedicada a las tres cuestiones sobre los universales. La parte “destructiva”, en la que Abelardo somete a crítica las doctrinas realistas de Guillermo de Champeaux no tiene un sentido meramente negativo, sino que busca llegar al punto de partida de la propia posición de Abelardo: las cosas no sólo difieren por sus formas (accidentes), sino también por sus materias (esencias). Al hablar de (...) la imagen correspondiente al nombre universal, Abelardo no se detiene a explicar la formación del concepto universal a partir de la cosa, sino que más bien se refiere a la significación intelectual de los términos, en tanto “generan intelecciones”. Esta omisión puede explicarse por el hecho de que, para Abelardo, la inteligencia humana rara vez o nunca llega a captar las esencias de las cosas. (shrink)

In this study, we propose considering membership in the Ethics Officer Association (EOA) as a proxy for the firm's commitment to ethical decision making, and we analyze the influence of firm- and CEO-specific characteristics on this commitment. While we observe a positive relationship between membership and firm size, we also document a negative relationship between EOA membership and the executive's time in position and, to a more modest extent, accounting returns. Pursuing this further, we present evidence that firms with past (...) legal issues may seek EOA membership as a signal of their intention to be compliant in the future. (shrink)

We study active set methods for optimization problems in Block Angular Form (BAF). We begin by reviewing some standard basis factorizations, including Saunders' orthogonal factorization and updates for the simplex method that do not impose any restriction on the pivot sequence and maintain the basis factorization structured in BAF throughout the algorithm. We then suggest orthogonal factorization and updating procedures that allow coarse grain parallelization, pivot updates local to the affected blocks, and independent block reinversion. A simple parallel environment appropriate (...) to the description and complexity analysis of test procedures is defined in Section 5. The factorization and updating procedures are presented in Sections 6 and 7. Our update procedure outperforms conventional Updating procedures even in a purely sequential environment. (shrink)

En el contexto político global contemporáneo, las diversas luchas sociales se están alienando entre sí hasta elpunto de que la ilusión del capitalismo como único sistema socioeconómico posible está difuminando todos los horizontesdel cambio social. En este artículo, trataremos de redefinir las causas comunes de las luchas sociales, demostrando su interseccionalidad e interdependencia. Para ello, nos ocuparemos de una serie de conceptos de la filosofía de Marx. En la introducción, examinaremos la noción de valor, afirmando que la teoría del valor (...) de Marx no es simplemente una teoría laboral del valor, sino que más bien refleja la estructura paralela de la producción y la circulación, cristalizada en la forma de valor última del dinero. Una vez obtenidas estas ideas preliminares, volveremos al fenómeno del trabajo en el capitalismo, para reinterpretar, en la primera sección del artículo, la distinción marxiana entre trabajo productivo e improductivo. A partir de ahí, se darán los primeros ejemplos concretos de la interseccionalidad de las luchas sociales contra la abstracción del capital: a saber, mostrar que las luchas de género y las raciales tienen ciertas causas comunes, enraizadas en la hegemonía gramsciana. En la segunda sección, examinaremos la distinción que Marx establece entre la subsunción formal y la real. Esta última, afirmaremos, es decisiva para entender cómo el capital estructura la cuasi-totalidad de nuestras relaciones sociales. Tras una interpretación de la película Toni Erdmann de Maren Ade, propondremos algunos medios posibles de lucha interseccional contra la subsunción real, que encontrarán su respaldo teórico en el concepto de universales subversivos. Las observaciones finales abordarán la lógica nuclear de la distribución y la acumulación del capital, un síntoma que pervive a lo largo de la historia preservado e impulsado por la omnipresencia de la ideología, y subrayarán de nuevo implícitamente la importancia de la lucha común en el descongelamiento de la emergencia de un nuevo sujeto revolucionario.

En el presente artículo se realiza una presentación sucinta de la obra del filósofo alemán Gottlob Frege, a través de una reseña de su obra desde dos puntos de vista: I) su obra vista cronológicamente y II) su obra como una serie que va desde los problemas relacionados con los fundamentos de la matemática, hasta una ampliación de dichos problemas más allá de las matemáticas. Se concluye señalando la importancia de Frege para la actual filosofía del lenguaje.

Las miopatías metabólicas son un grupo de trastornos genéticos que disminuyen la capacidad del músculo esquelético para utilizar sustratos energéticos y sintetizar ATP. Estas alteraciones pueden clasificarse en tres tipos fundamentalmente: i) trastornos del metabolismo de los carbohidratos (del glucógeno y de la glucosa), ii) defectos del metabolismo lipídico, y iii) alteraciones de la fosforilación oxidativa –OXPHOS-. Las dos primeras se deben a deficiencias enzimáticas de las rutas metabólicas de degradación y síntesis de glúcidos y lípidos y muestran diversas manifestaciones (...) clínicas, pero una buena parte de ellas cursan con intolerancia al ejercicio. Aunque un buen número de pacientes con estos trastornos musculares presentan síntomas en la infancia, el diagnóstico normalmente se retrasa hasta la segunda y tercera década de la vida. Por tanto, reconocer las características clínicas de estas deficiencias conduce a un diagnóstico precoz y a un mejor tratamiento. Las enfermedades mitocondriales son un grupo de trastornos originados por una deficiencia en la síntesis de ATP a través del sistema de fosforilación oxidativa. Este sistema está formado por proteínas codificadas en los dos genomas de la célula (nuclear y mitocondrial) y, por tanto, pueden presentar un modelo de herencia mendeliano o materno. En esta revisión se describirán las características especiales del sistema genético mitocondrial y las principales mutaciones que causan enfermedades en humanos. (shrink)

Wind turbines have been used by many groups of humans for many centuries. Wind turbines have allowed groups of humans to perform many different tasks in the past. However, only a century and a half ago, they began to be used to convert the energy captured from wind into electric energy. Moreover, only approximately twenty-five years ago, we started to introduce on a massive scale the energy generated from wind turbines into the electric networks of most developed countries in the (...) world for regular consumption. According to 2017 statistics, approximately 12 percent of the electric energy consumed in the EU is produced by wind turbines. Despite the fact that wind turbines generally appear quite similar externally—i.e., a three-blade structure, a nacelle, a tower, etc.—if we carefully examine the electric technology used within them, we find quite a wide range of technologies for energy conversion, which is a key issue in wind turbine technology. Hence, this paper adopts a dialectic perspective towards analyzing and understanding why several electric technologies coexist in wind turbine technology. We explain the specific factors that have influenced different wind turbine manufacturers to adopt different electric technologies across the last twenty-five years. We show how their actions and the technological directions that have followed have been mutually codetermined, resulting in a technological evolution that has produced today’s wind turbine variety.

This article explores the philosophy of Alain Badiou from the vantage point of the concepts of the localization, delocalization, and relocalization of the void as thematized through literary arts, religion, emancipatory politics, and the subject of psychoanalysis. In short, these moments around the void characterize the processes through which truth is processed and seen through their full realization by a philosophical engagement across the various conditions in which these truths occur. The localization of a void is the naming of an (...) indiscernible element that is incommensurable to the rubric of constructible knowledge, sense and meaning which could saturate the space of truth. Thus, the naming that localizes the void acts as a subtraction of the invariant in the variance of situation such that across various points in space and time, we are still able to subtract the universal as the invariant not just as the fidelity to the localized truth but also as the resurrection of truth upon its relocalization at a different place and a different time. At its core, this article is concerned with truth, why truth is persistent, and why we have to struggle to articulate the truth that we are trying to be faithful to again and again with each instance that truth risks being covered-over and obscured.

Este artículo explora el concepto de trauma colectivo y su aplicación en el contexto histórico y social de las sociedades latinoamericanas. La transferencia del término «trauma colectivo» desde el campo del conocimiento psicológico a la esfera social e histórica plantea preguntas sobre su legitimidad y marco conceptual. El estudio examina la fidelidad de esta transferencia conceptual y su relación con la comprensión psicoanalítica temprana de los fenómenos traumáticos. El contexto cultural europeo de finales del siglo xix y principios del siglo (...) xx proporcionó la base para teorizar las consecuencias de experiencias intensas y violentas, lo que resultó en el concepto de «neurosis traumática», influenciado significativamente por el trabajo de Freud. El artículo discute la apropiación de herramientas psicoanalíticas en la crítica histórica y cultural para comprender eventos que desafían marcos tradicionales y la inteligibilidad social, como el Holocausto. La noción del trauma como una fuerza enigmática y recurrente en la experiencia histórica se explora a través del enfoque de los estudios del trauma. El artículo pone de relieve a destacados y destacadas académicas en este campo y su uso de conceptos psicoanalíticos, demostrando la preservación y aplicación significativa de estas nociones en la comprensión de fenómenos históricos y colectivos. Al acortar la brecha entre las experiencias psicológicas individuales y los traumas colectivos, los estudios del trauma ofrecen un enfoque único para interpretar y representar eventos que resisten las narrativas históricas tradicionales.

El artículo aborda la pandemia del covid-19 como elemento contingente y su efecto de develamiento respecto de algunas manifestaciones contemporáneas de la ideología neoliberal en Latinoamérica. De esta forma, en base a conceptos filosóficos y psicoanalíticos de orientación lacaniana planteados fundamentalmente por Slavoj Žižek, se examinan los usos críticos de la noción de ideología en sus diversas manifestaciones: miedo al otro, imposición de la lógica del empresario de sí, destrucción de lazos sociales, extractivismo de recursos naturales y fetichización de los (...) discursos de unidad frente a la pandemia. La hipótesis radica en que la pandemia presenta una oportunidad para repensar la subjetividad contemporánea, mediante la confrontación con el Real que bordea a la simbolización y, en definitiva, a la captura ideológica, a fin de poner en cuestión la afirmación de que no hay alternativa.

The objective of this study was to develop and determine the psychometric properties of an instrument designed to detect traits and behavior that are associated with predatory violent behavior, which is defined as a determined, planned, controlled, and proactive aggression. The sample was comprised of 546 students, mostly in their last year of high school or in their first year of college. The initial instrument had 78 items, ultimately resulting in 15 with good internal consistency (α =.825). Factor analysis showed (...) four factors: anger-in, appeal for weapons, suicidal ideation, and the tendency to take justice into one’s own hands. Said factors showed significant correlations of convergent validity. Data shown here allows inferring that the instrument is a novel and concise tool that evaluates and detects the potential of predatory violent behavior. (shrink)

Subjective well-being is a broad category of phenomena that includes people’s emotional responses, domain satisfactions, and global judgments of life satisfaction. This research investigates how schoolchildren’s subjective well-being is affected by the different types of technology use, in personal contexts, and, concurrently, whether these effects are different when the use of technology is problematic. The central hypotheses are as follows: the use of the Internet affects the subjective well-being of schoolchildren negatively only when this use is problematic and the effect (...) on subjective well-being is different according to the type of Internet use. To respond to the objectives of the research, a survey was applied to 15-year-old adolescents, distributed in 330 public schools, beneficiaries of a government program for the delivery of personal computers and Internet for a year. The different uses of the Internet were measured using frequency scales by type of activity. Problematic use scale measured the perception of negative consequences of the intensity of Internet use on a daily basis. Subjective well-being was measured by the Personal Well-Being Index-School Children. Subsequently, for analytical purposes, three simple mediation models were created, whose dependent variable was PWI-SC, while its independent variables were Internet use scales differentiated by purpose and problematic use as a mediating variable, as well as attributes of the subjects and their social environment, which were incorporated as control variables. The main results show that only if Internet use is expressed as problematic does it negatively affect subjective well-being. On the contrary, when the use of the Internet is not problematic, the effect is positive and even greater than the simple effect between these two variables. This finding is relevant, since it allows us to provide evidence that suggests that, when studying the effect that the intensity of the Internet, firstly, one must consider the mediating effect exerted by the network’s problematic use and, secondly, that not all types of use have the same impact. Therefore, it is useful to enrich the discussion on subjective well-being and social integration of schoolchildren in the digital age. (shrink)

El presente trabajo propone determinadas aproximaciones iusfilosóficas al discurso jurídico, a partir de los estudios realizados por Walter Benjamin sobre Franz Kafka. La investigación se realiza con las herramientas metodológicas que aportan las “teorías críticas del derecho” y los marcos teóricos que indagan la relación “derecho-literatura”. Los textos, discusiones y apuntes realizados por el pensador alemán permiten movilizar un análisis de determinados tópicos y categorías pertenecientes al espacio jurídico. Las investigaciones que realiza en torno a la figura de Kafka ofrecen (...) insumos para indagar la formación, despliegue y conservación del derecho. Desde la obra kafkiana, Benjamin visibiliza y desarticula los conceptos nodales de justicia, ley, poder y violencia, lo que permite dar cuenta de los mecanismos y dispositivos que hacen posible el sustento mitológico del derecho.

Many believe that the ethical problems of donation after cardiocirculatory death (DCD) have been "worked out" and that it is unclear why DCD should be resisted. In this paper we will argue that DCD donors may not yet be dead, and therefore that organ donation during DCD may violate the dead donor rule. We first present a description of the process of DCD and the standard ethical rationale for the practice. We then present our concerns with DCD, including the following: (...) irreversibility of absent circulation has not occurred and the many attempts to claim it has have all failed; conflicts of interest at all steps in the DCD process, including the decision to withdraw life support before DCD, are simply unavoidable; potentially harmful premortem interventions to preserve organ utility are not justifiable, even with the help of the principle of double effect; claims that DCD conforms with the intent of the law and current accepted medical standards are misleading and inaccurate; and consensus statements by respected medical groups do not change these arguments due to their low quality including being plagued by conflict of interest. Moreover, some arguments in favor of DCD, while likely true, are "straw-man arguments," such as the great benefit of organ donation. The truth is that honesty and trustworthiness require that we face these problems instead of avoiding them. We believe that DCD is not ethically allowable because it abandons the dead donor rule, has unavoidable conflicts of interests, and implements premortem interventions which can hasten death. These important points have not been, but need to be fully disclosed to the public and incorporated into fully informed consent. These are tall orders, and require open public debate. Until this debate occurs, we call for a moratorium on the practice of DCD. (shrink)

Notwithstanding the potential danger to security and privacy, sharing and publishing data has become usual in Data Science. To preserve privacy, de-identification methodologies guided by risk estimation have been designed. Two issues associated with classical risk metrics are, on the one hand, the adequacy of the metric and, on the other hand, its static nature. In this paper, we present metrics for estimating risk based on the emerging semantics provided by Formal Concept Analysis. The metrics are designed to estimate the (...) a priori risk of compromised data deletion. Furthermore, by applying specialized variable forgetting methods for association rules, it is shown how to reflect the effect of deleting attributes belonging to potentially dangerous quasi-identifier sets. Additionally, a study of the role of the risk metric in confidence-based reasoning for re-identification is presented. (shrink)
