Fall detection is a challenging task that has received the attention of the research community in the recent years. This study focuses on FD using data gathered from wearable devices with tri-axial accelerometers, developing a solution centered in elderly people living autonomously. This research includes three different ways to improve a FD method: an analysis of the event detection stage, comparing several alternatives, an evaluation of features to extract for each detected event and an appraisal of up to 6 different (...) clustering scenarios to split the samples in subsets that might enhance the classification. For each clustering scenario, a specific classification stage is defined. The experimentation includes publicly available simulated fall data sets. Results show the guidelines for defining a more robust and efficient FD method for on-wrist 3DACC wearable devices. (shrink)

Contemporary biological research has suggested that some host–microbiome multispecies systems (referred to as “holobionts”) can in certain circumstances evolve as unique biological individual, thus being a unit of selection in evolution. If this is so, then it is arguably the case that some biological adaptations have evolved at the level of the multispecies system, what we call hologenomic adaptations. However, no research has yet been devoted to investigating their nature, or how these adaptations can be distinguished from adaptations at the (...) species-level (genomic adaptations). In this paper, we cover this gap by investigating the nature of hologenomic adaptations. By drawing on the case of the evolution of sanguivory diet in vampire bats, we argue that a trait constitutes a hologenomic adaptation when its evolution can only be explained if the holobiont is considered the biological individual that manifests this adaptation, while the bacterial taxa that bear the trait are only opportunistic beneficiaries of it. We then use the philosophical notions of emergence and inter-identity to explain the nature of this form of individuality and argue why it is special of holobionts. Overall, our paper illustrates how the use of philosophical concepts can illuminate scientific discussions, in the trend of what has recently been called metaphysics of biology. (shrink)

Bourrat and Griffiths :33, 2018) have recently argued that most of the evidence presented by holobiont defenders to support the thesis that holobionts are evolutionary individuals is not to the point and is not even adequate to discriminate multispecies evolutionary individuals from other multispecies assemblages that would not be considered evolutionary individuals by most holobiont defenders. They further argue that an adequate criterion to distinguish the two categories is fitness alignment, presenting the notion of fitness boundedness as a criterion that (...) allows divorcing true multispecies evolutionary individuals from other multispecies assemblages and provides an adequate criterion to single out genuine evolutionary multispecies assemblages. A consequence of their criterion is that holobionts, as conventionally defined by hologenome defenders, are not evolutionary individuals except in very rare cases, and for very specific host-symbiont associations. This paper is a critical response to Bourrat and Griffiths’ arguments and a defence of the arguments presented by holobiont defenders. Drawing upon the case of the hologenomic basis of the evolution of sanguivory in vampire bats, I argue that Bourrat and Griffiths overlook some aspects of the biological nature of the microbiome that justifies the thesis that holobionts are evolutionarily different to other multispecies assemblages. I argue that the hologenome theory of evolution should not define the hologenome as a collection of genomes, but as the sum of the host genome plus some traits of the microbiome which together constitute an evolutionary individual, a conception I refer to as the stability of traits conception of the hologenome. Based on that conception I argue that the evidence presented by holobiont defenders is to the point, and supports the thesis that holobionts are evolutionary individuals. In this sense, the paper offers an account of the holobiont that aims to foster a dialogue between hologenome advocates and hologenome critics. (shrink)

The hologenome concept of evolution is a hypothesis about the evolution of animals and plants. It asserts that the evolution of animals and plants was partially triggered by their interactions with their symbiotic microbiomes. In that vein, the hologenome concept posits that the holobiont (animal host + symbionts of the microbiome) is a unit of selection. -/- The hologenome concept has been severely criticized on the basis that selection on holobionts would only be possible if there were a tight transgenerational (...) host-genotype-to-symbiont-genotype connection. As our current evidence suggests that this is not the case for most of the symbiont species that compose the microbiome of animals and plants, the opportunity for holobiont selection is very low in relation to the opportunity for selection on each of the species that compose the host microbiome. Therefore, holobiont selection will always be disrupted ‘from below’, by selection on each of the species that compose the microbiome. -/- This thesis constitutes a conceptual effort to defend philosophically the hologenome concept. I argue that the criticism according to which holobiont selection requires tight transgenerational host-genotype-to-symbiont-genotype connection is grounded on a metaphysical view of the world according to which the biological hierarchy needs to be nested, such that each new level of selection includes every entity from below. Applied to hologenomes, it entails that the hologenome is a collection of genomes, and selection of hologenomes is assumed to entail cospeciation of the host with the species that constitute its microbiome. -/- Against that interpretation, I propose the ‘stability of traits’ account, according to which hologenome evolution is the result of the action of natural selection in a non-nested hierarchical world. In that vein, hologenome evolution does not entail cospeciation, and thus it does not require tight transgenerational host-genotype-to-symbiont-genotype connection. By embracing a multilevel selection perspective, I argue that hologenome evolution results from the simultaneous action of natural selection on each of the lineages that compose the microbiome, and on the assemblage composed by the host genome plus the functional traits of its microbiome. Hologenome selection occurs when the evolution of the traits of the microbiome result from their effects on the fitness of the host, and it can take the form of multilevel selection 1, or multilevel selection 2. In both cases, hologenome selection entails the evolution of microbiome traits, as well as evolution of the host genome, rather than cospeciation of lineages. (shrink)

La ciencia de la política en el siglo veinte ha llegado a una difícil situación. La vida ha sufrido convulsiones inesperadas mientras que la ciencia que debía entender lo sucedido ha quedado apresada por la perplejidad y pos sus fracasos en la predicción y explicación de los acontecimientos. En tono crítico, el autor mantiene que "una ciudadanía de hombres y mujeres vigilantes es un dogma nuevo que no debe pasar desapercibido". La emancipación colonial, el holocausto, la caída del muro de (...) Berlín y las transformaciones vertiginosas de la tecnología han arrastrado a la ciencia política y a sus investigadores a una situación comprometida. En este libro, el autor reconstruye la teoría política del siglo veinte a través de sus grandes maestros y reclama un saber que no se separe de los hombres y mujeres que dan vida a la política cotidiana y real.

While punishment is a longstanding object of philosophical scrutiny, other controversial aspects of the justice system, such as policing, have flown under the radar. In this paper, we consider possible reasons why philosophers interested in crime and punishment have neglected policing. We make the case for a broader account of the political morality of the justice system, with a particular emphasis on policing. We sketch the outlines of an egalitarian version of such a theory, highlighting parallels between policing and the (...) welfare state. Finally, we turn to recent calls for police abolition. Evaluating such radical claims requires, we argue, going beyond the traditional confines of the philosophy of punishment and considering a more holistic and interdisciplinary theory of criminal justice.

The units or levels of selection debate concerns the question of what kind of biological systems are stable enough that part of their evolution is a result of the process of natural selection acting at their level. Traditionally, the debate has concerned at least two different, though related, questions: the question of the level at which interaction with the environment occurs, and the question of the level at which reproduction occurs. In recent years, biologists and philosophers have discussed a new (...) aspect of this debate, namely the possibility that certain multi-species consortia formed by a host and its microbiome may act as a unit of selection. This thesis, however, has not been without criticism, as it is doubtful that such consortia could meet the conditions required to achieve the degree of stability that would allow them to experience natural selection. The purpose of this paper is to systematically examine such criticisms and to defend the thesis that the holobiont/hologenome can act as a genuine level of selection both in the form of an interactor and in the form of a reproducer. To do so, it will be argued that the microbiome should be characterized in functional rather than taxonomic terms. (shrink)

El objetivo que se persigue en este trabajo es el de aproximar el pensamiento de Max Weber y Leonardo Polo en torno a la conexión de los tipos ideales sociales. La fecundidad de este diálogo se plasmará en la distinta propuesta metodológica con la que uno y otro aborda esta cuestion. El interés de esa diversa metodología permite la comprensión de la realidad social de modo distinto y la forma en que abordan la consistencia social.

Este estudio es una aproximación al tema del trabajo desde el pensamiento sociológico de Zygmunt Bauman. Uno de los textos más conocidos de Bauman al respecto es Trabajo, consumismo y nuevos pobres; sin embargo, este es un tema que el sociólogo trata en otras obras. Aquí se pretende dar una visión en la que se tienen en cuenta la globalidad de sus escritos. Además, se dan unas claves que permiten comprender el enfoque que Bauman tiene del trabajo: se hace una (...) breve explicación de su perspectiva sociológica y de la importancia de la modernidad en su pensamiento. Por último, se expone cómo el trabajo cambia de sentido e importancia en la modernidad sólida y en la líquida. (shrink)

In this article we are going to approach the question of the intersubjectivity. To understand why the intersubjectivity is a modern problem and which is the solution that it fits, we have chosen to follow a descending route that gives light and should illuminate what today, in many areas, is seen as a problem. We will begin, consequently, approaching the person as not identical but dual. The above mentioned cosideration takes us from the hand to the distinction between someone and (...) something that reveals the unlimited character of the person. The distinction indicates that what is own of the person is to coexist, that is to say, that there cannot be only one person. Thus, monism is incompatible with the personal being and, having reached the person as coexistence, the discoveries are extended on to intersubjectivity, proper of modern anthropology. (shrink)

The Light Subject Constraint in Spoken Spanish The purpose of this study is to explore Chafe's hypothesis that grammatical subjects obey the light subject constraint. The data consists of six half-an-hour semiformal interviews with Caracas native speakers recorded in 1987. Chafe's hypothesis is based on the claim that in any given clause one of the referents receives the unique and special status of grammatical subject. Subjects show two types of restrictions: i) from the information load perspective, they tend to code (...) given or accessible rather than new information; and ii) from a referential viewpoint, they can have three degrees of importance: primary, secondary or trivial. Information load and referential importance combined constitute the LSC: Chafe's findings prove that in English subjects tend, on the one hand, to be given or accessible and, on the other, of primary or secondary importance. Heavy subjects, on the contrary, tend to be of trivial importance. Broderick 1999 confirms the LSC's existence in a conversational English corpus. All subjects in the corpus have been coded according to information load and referential importance. The results of the analysis show that spoken Spanish also conforms to LSC. (shrink)

The paper defends an interactive theory of the distinctiveness of criminal law. It argues that criminal law’s distinctive behavior can be connected to the interaction between five traits: it is an institutional practice administered by a large and special bureaucracy, playing a substantial role in authorizing the use of coercive police force, leading to a harsh sanctioning regime linked, at least in part, with core wrongs and notions of personal responsibility. Although none of these features is exclusive to criminal law, (...) their interaction leads to modes of behavior that set it apart from other institutions. The paper argues that putting attention on the effects of this interaction provides us with powerful tools to both understand and asses the value and problems of criminal law. (shrink)

Ortega trasladó sus ideas pedagógicas a su quehacer como profesor universitario. Muchos de sus discípulos y colaboradores han dejado constancia de ello, como aquí se refiere. Fue para ellos, sobre todo ejemplo, ejemplo de vida, de orientación vital, de sinceridad intelectual en su quehacer filosófico. En este artículo no analizamos la filosofía de Ortega, lo que hemos hecho en otros textos, sino el impacto que causó la «persona» Ortega en sus colaboradores y discípulos. Aunque es algo estudiando, nunca se ha (...) presentado de esta forma sintética que muestra la envergadura del impacto que Ortega produjo en el mundo intelectual de la Edad de Plata de la cultura española.

Symbiosis plays a fundamental role in contemporary biology, as well as in recent thinking in philosophy of biology. The discovery of the importance and universality of symbiotic associations has brought new light to old debates in the field, including issues about the concept of biological individuality. An important aspect of these debates has been the formulation of the hologenome concept of evolution, the notion that holobionts are units of natural selection in evolution. This review examines the philosophical assumptions that underlie (...) recent proposal of the hologenome concept of evolution, and traces those debates back in time to their historical origins, to the moment when the connection between the topics of symbiosis and biological individuality first caught the attention of biologists. The review is divided in two parts. The first part explores the historical origins of the connection between the notion of symbiosis and the concept of biological individuality, and emphasizes the role of A. de Bary, R. Pound, A. Schneider and C. Merezhkowsky in framing the debate. The second part examines the hologenome concept of evolution and explores four parallelisms between contemporary debates and the debates presented in the first part of the essay, arguing that the different debates raised by the hologenome concept were already present in the literature. I suggest that the novelty of the hologenome concept of evolution lies in the wider appreciation of the importance of symbiosis for maintaining life on Earth as we know it. Finally, I conclude by suggesting the importance of exploring the connections among contemporary biology, philosophy of biology and history of biology in order to gain a better understanding of contemporary biology.

Holobionts are symbiotic assemblages composed by a host plus its microbiome. The status of holobionts as individuals has recently been a subject of continuous controversy, which has given rise to two main positions: on the one hand, holobiont advocates argue that holobionts are biological individuals; on the other, holobiont detractors argue that they are just mere chimeras or ecological communities, but not individuals. Both parties in the dispute develop their arguments from the framework of the philosophy of biology, in terms (...) of what it takes for a “conglomerate” to be considered an interesting individual from a biological point of view. However, the debates about holobiont individuality have important ontological implications that have remained vaguely explored from a metaphysical framework. The purpose of this paper is to cover that gap by presenting a metaphysical approach to holobionts individuality. Drawing upon a conception of natural selection that puts the focus on the transgenerational recurrence of the traits and that supports the thesis that holobionts are units of selection, we argue that holobionts bear emergent traits and exert downward powers over the entities that compose them. In this vein, we argue, a reasonable argument can be made for conceiving holobionts as emergent biological individuals. (shrink)

Given one conception of biological individuality (evolutionary, physiological, etc.), can a holobiont – that is the host + its symbiotic (mutualistic, commensalist and parasitic) microbiome – be simultaneously a biological individual and an ecological community? Herein, we support this possibility by arguing that the notion of biological individuality is part‐dependent. In our account, the individuality of a biological ensemble should not only be determined by the conception of biological individuality in use, but also by the biological characteristics of the part (...) of the ensemble under investigation. In the specific case of holobionts, evaluations of their individuality should be made either host‐relative or microbe‐relative. We support the claim that biological individuality is part‐dependent by drawing upon recent empirical evidence regarding the physiology of hosts and microbes, and the recent characterization of the ‘demibiont’. Our account shows that contemporary disagreements about the individuality of the holobiont derive from an incorrect understanding of the ontology of biological individuality. We show that collaboration between philosophers and biologists can be very fruitful in attempts to solve some contemporary biological debates. (shrink)

El propósito de este artículo es desarrollar una relectura al mecanicismo moderno. Esto implica que una adecuada comprensión de este consiste, ante todo, en considerarlo como un proyecto antes que un sistema doctrinal consolidado. Para ello se toma como eje la filosofía de Leibniz, la cual, a diferencia del cartesianismo, identifica las inconsistencias que implica concebir el mecanicismo como un sistema filosófico completo, principalmente al pretender justificar mecánicamente el mundo natural, esto es, a partir de la figura, el tamaño y (...) el movimiento. Todo lo anterior no implica un rechazo completo del mecanicismo por parte de Leibniz, sino que permite concebirlo como un medio para desarrollar su filosofía, proponiendo una complementariedad entre la causa final y la causa eficiente. de este modo, el mecanicismo es reubicado como un problema metodológico para la ciencia natural antes que como un problema metafísico. This article aims to develop a second reading to the modern mechanicism. This implies that an appropriate understanding of mechanicism consists, above all, in considering it as a project, instead of a consolidated doctrinal system. To do so, we take Leibniz's philosophy as our building blocks, since unlike the Cartesianism, it does identify the inconsistencies implied when we conceive mechanicism as a complete philosophical system, mainly under the pretension to justify the natural world mechanically, that is, based on the figure, size and movement. It does not imply that Leibniz rejects entirely mechanicism, but allows us to understand it as a mean to develop his philosophy, proposing a complementary relationship between final cause and efficient cause. This way, mechanicism is re-posed as a methodological issue for the natural science instead of a metaphysical issue. (shrink)

Philippe Huneman has recently questioned the widespread application of mechanistic models of scientific explanation based on the existence of structural explanations, i.e. explanations that account for the phenomenon to be explained in virtue of the mathematical properties of the system where the phenomenon obtains, rather than in terms of the mechanisms that causally produce the phenomenon. Structural explanations are very diverse, including cases like explanations in terms of bowtie structures, in terms of the topological properties of the system, or in (...) terms of equilibrium. The role of mathematics in bowtie structured systems and in topologically constrained systems has recently been examined in different papers. However, the specific role that mathematical properties play in equilibrium explanations requires further examination, as different authors defend different interpretations, some of them closer to the new-mechanistic approach than to the structural model advocated by Huneman. In this paper, we cover this gap by investigating the explanatory role that mathematics play in Blaser and Kirschner’s nested equilibrium model of the stability of persistent long-term human-microbe associations. We argue that their model is explanatory because: i) it provides a mathematical structure in the form of a set of differential equations that together satisfy an ESS; ii) that the nested nature of the ESSs makes the explanation of host-microbe persistent associations robust to any perturbation; iii) that this is so because the properties of the ESS directly mirror the properties of the biological system in a non-causal way. The combination of these three theses make equilibrium explanations look more similar to structural explanations than to causal-mechanistic explanation. (shrink)

This paper aims to offer a new argument in defence bacterial species pluralism. To do so, I shall first present the particular issues derived from the conflict between the non-theoretical understanding of species as units of classification and the theoretical comprehension of them as units of evolution. Secondly, I shall justify the necessity of the concept of species for the bacterial world, and show how medicine and endosymbiotic evolutionary theory make use of different concepts of bacterial species due to their (...) distinctive purposes. Finally, I shall show how my argument provides a new source of defence for bacterial pluralism. (shrink)

Despite the increase in the research field of ethics in artificial intelligence, most efforts have focused on the debate about principles and guidelines for responsible AI, but not enough attention has been given to the “how” of applied ethics. This paper aims to advance the research exploring the gap between practice and principles in AI ethics by identifying how companies are applying those guidelines and principles in practice. Through a qualitative methodology based on 22 semi-structured interviews and two focus groups, (...) the goal of the current study is to understand how companies approach ethical issues related to AI systems. A structured analysis of the transcripts brought out many actual practices and findings, which are presented around the following main research topics: ethics and principles, privacy, explainability, and fairness. The interviewees also raised issues of accountability and governance. Finally, some recommendations are suggested such as developing specific sector regulations, fostering a data-driven organisational culture, considering the algorithm’s complete life cycle, developing and using a specific code of ethics, and providing specific training on ethical issues. Despite some obvious limitations, such as the type and number of companies interviewed, this work identifies real examples and direct priorities to advance the research exploring the gap between practice and principles in AI ethics, with a specific focus on Spanish companies.

La muerte de Hegel es tomada frecuentemente por los intérpretes como el acontecimiento que marca el final de la metafísica. Lo que generalmente se asume con ello no es sólo una determinada periodización de la historia de la filosofía, sino también una muy determinada interpretación de su “final” como agotamiento de algo que ha llegado al final de sus fuerzas y se desvanece como algo caduco y obsoleto. Pero si esto es así, ¿cómo explicar entonces los constantes repuntes del hegelianismo (...) a lo largo del s. XX? ¿Son las últimas apariciones de una sombra del pasado que se deja ver por última vez antes de desvanecerse por completo? ¿O son más bien las manifestaciones de un espíritu vivo que se niega a ser enterrado como un “perro muerto”? ¿Es verdaderamente la muerte de Hegel como la del perro, o más bien como la de espíritu que mira a la muerte a los ojos y emerge renovado de ella? ¿Son las diversas reacciones contra Hegel que se suceden a lo largo del pensamiento postmetafísico la clara expresión histórica de una nueva conciencia filosófica que ha conseguido romper el lazo con la metafísica, o son más bien el síntoma de una nueva enajenación del espíritu destinada a escribir un nuevo capítulo de la Historia universal? El objetivo de este artículo es evidenciar el hegelianismo como el momento decisivo y final del despliegue del espíritu en el camino hacia la autoconciencia universal. (shrink)
