The book presents insights from a mixed methodology study that examines recent mobility patterns exhibited by the middle classes. Its major contributions are two-fold: theoretically, it advances the conceptualisation of middle class migration; empirically, it analyses the migratory motivations of a relatively new Latin-American group in Australia. The accelerated insertion of the Mexican society into globalisation processes is strongly linked not only to the growing participation in migration phenomena but also to people's outflow to new destinations. Although studies of Mexican (...) emigration are vast, research on Mexican skilled migration is scarce, and research that focuses on mobility to non-USA destinations is even scarcer. Mexicans are a relatively new addition to Australia's multicultural society, and little is known about this group's profile and why they choose to migrate to Australia. Employing a mixed methodology approach, the book provides a comprehensive portrait of migration in a new group. (shrink)

Assessing physical fitness has emerged as a proxy of the health status of children and adolescents and therefore as relevant from a public health point of view. DAFIS is a project included in Plan Galicia Saudable of the regional government of Galicia. DAFIS consists of an on-line software devoted to record the results of a standard physical fitness protocol carried out as a part of the physical education curriculum. The aims of this study were: to obtain normative values of physical (...) fitness of the Galician school population evaluated in the DAFIS project, and to identify a reduced number of components and tests able to capture a significant amount of the variability in the physical fitness of children and adolescents. From an initial sample of 27784 records, 15287 cases were considered after filtering. Generalized Additive Models for Location, Scale and Shape were used for obtaining percentile curves and tables for each sex. Furthermore, a principal components analysis was performed, selecting the number of components by applying the Kaiser’s rule and selecting a subset of variables considering the correlation between each variable and the components. Percentile curves and normative values are reported for each test and sex. Physical fitness was better in boys than in girls throughout age groups, except for flexibility that was consistently higher in girls. Two main components were detected throughout age groups: the first one representing body composition and partially cardiorespiratory fitness and the second one muscular fitness. For boys and girls, waist to height ratio had the highest correlations with the first component in four out of six age groups. The highest correlation with the second component, was most frequently observed for the handgrip test both in boys and girls. This study provides evidence about the utility of school community actions like DAFIS aimed to track the health-related fitness of children and adolescents. The results suggest that fat mass distribution and muscular performance concentrate a high proportion physical fitness variance. (shrink)

IntroductionRheumatologists are the primary healthcare professionals responsible for patients with rheumatic diseases and should acquire medical ethical competencies, such as the informed consent process. The objective clinical structured examination is a valuable tool for assessing clinical competencies. We report the performance of 90 rheumatologist trainees participating in a station designed to evaluate the ICP during the 2018 and 2019 national accreditations.MethodsThe station was validated and represented a medical encounter in which the rheumatologist informed a patient with systemic lupus erythematosus with (...) clinically active nephritis about renal biopsy. A trained patient–actor and an evaluator were instructed to assess ICP skills in obtaining formal informed consent, delivering bad news and overall communication with patients. The evaluator used a tailored checklist and form.ResultsCandidate performance varied with ICP content and was superior for potential benefit information but significantly reduced for potential complications and biopsy description. Only 17.8% of the candidates mentioned the legal perspective of ICP. Death was omitted by the majority of the candidates ; after the patient–actor challenged candidates, only 57.1% of them gave a clear and positive answer. Evaluators frequently rated candidate communications skills as superior, but ≥1 negative aspect was identified in 69% of the candidates.ConclusionsEthical competencies are mandatory for professional rheumatologists. It seems necessary to include an ethics competency framework in the curriculum throughout the rheumatology residency. (shrink)

IntroductionThis study aimed to evaluate, in adults with mild cognitive impairment, the brain atrophy that may distinguish between three AT biomarker-based profiles, and to determine its clinical value.MethodsStructural MRI was employed to evaluate the volume and cortical thickness differences in MCI patients with different AT profiles, namely, A−T−−: normal AD biomarkers; A+T−−: AD pathologic change; and A+T++: prodromal AD. Sensitivity and specificity of these changes were also estimated.ResultsAn initial atrophy in medial temporal lobe areas was found in the A+T−− and (...) A+T++ groups, spreading toward the parietal and frontal regions in A+T++ patients. These structural changes allowed distinguishing AT profiles within the AD continuum; however, the profiles and their pattern of neurodegeneration were unsuccessful to determine the current clinical status.ConclusionsMRI is useful in the determination of the specific brain structural changes of AT profiles along the AD continuum, allowing differentiation between MCI adults with or without pathological AD biomarkers.

En el presente trabajo se realizará un análisis y comparación críticos de las ideas con relación a la tecnología desarrolladas por Eduardo Nicol y Adolfo Sánchez Vázquez. En ese sentido, se confrontará el concepto de “razón de fuerza mayor” de Nicol con la idea del “racionalismo tecnológico” de Sánchez Vázquez. Demostrando, finalmente, que el concepto nicoliano encajaría perfectamente dentro de los parámetros de la ideología del racionalismo tecnológico tal y como la define Adolfo Sánchez Vázquez. Todo ello (...) con el fin de valorar el alcance y las limitaciones de las propuestas de ambos autores y su posible vigencia de cara a pensar un problema tan actual como el de la tecnología y la responsabilidad del ser humano en su desarrollo. Así pues, este trabajo no se propone estudiar un diálogo o polémica real entre los autores en cuestión ni tampoco se hace cargo de una crítica explícita de uno a otro. Lo que se busca es conectar dos desarrollos filosóficos aparentemente alejados (la metafísica fenomenológica de Nicol y el marxismo crítico de Sánchez Vázquez) examinando cómo abordan uno y otro el tema de la tecnología y destacando las hipotéticas implicaciones de uno de esos desarrollos sobre el otro. Para ello, se parte de una breve explicación del contexto histórico de ambos pensadores, luego se enmarcan las ideas de la tecnología de cada uno en su contrastante concepción de la praxis, se muestran los puntos en común y las discrepancias y, finalmente, se termina señalando la hipotética repercusión de las ideas Sánchez Vázquez sobre las de Nicol.

En este artículo se plantea la fertilidad del pensamiento marxista de Adolfo Sánchez Vázquez (1915-2011) al abordar los desafíos inherentes al desarrollo tecnológico. Se busca ofrecer una aproximación al pensamiento del autor acerca de la tecnología, temática tratada de manera implícita a lo largo de su obra. De esta manera, se aborda una cuestión apenas explorada en los estudios sobre Sánchez Vázquez, abriendo así la puerta a posteriores investigaciones sobre del tema. El trabajo se divide en tres partes. (...) Una primera, en la que se presenta someramente su filosofía de la praxis a partir de la hipótesis hermenéutica de la «trayectoria intelectual elíptica». Esta hipótesis de lectura permitirá comprender la obra de Sánchez Vázquez como articulada en torno a dos grandes preocupaciones principales: la creatividad y la emancipación política. Dos preocupaciones que definirán, a su vez, las reflexiones del autor acerca de la tecnología. En esta línea, será en la segunda parte donde se aborde la lectura sanchezvazquiana de la tecnología y su concepto de «racionalismo tecnológico». Finalmente, en la tercera parte, se proponen tres ámbitos estrechamente relacionados con el desarrollo tecnológico a los que las ideas del autor -marcadas por la doble preocupación anteriormente señalada-harían una contribución relevante: el de la ecología, el de la filosofía del trabajo y el de la socialización de la creación.

Experiential imagination consists in an imaginative projection that aims at simulating the experiences one would undergo in different circumstances. It has been traditionally thought to play a role in how we build our lives, engage with other agents, and appreciate art. Although some philosophers have recently expressed doubts over the capacity of experiential imagination to offer insight into the perspective of someone other than our present-selves, experiential imagination remains a much sought-after tool. This paper substantiates pessimism about the epistemological value (...) of these uses of experiential imagination by developing an embodied approach. Our thesis is that experiential imagination is _robustly embodied_ because the _sociohistorically situated_ body makes an irreducible contribution to the imaginative project, and that, as such, it is constrained by who we are as _concrete_ agents. We argue that experiential imagination is an embodied, virtual exploration of imagined scenarios that depends on our situated history of sensorimotor and affective interactions. We conclude that experiential imagination is much more limited than commonly acknowledged, as it can hardly be divorced from who we are and where we have been. (shrink)

Advocates of interactionism in the ethical criticism of art argue that ethical value impacts aesthetic value. The debate is concerned with “the intrinsic question”: the question of whether ethical flaws/merits in artworks’ manifested attitudes affect their aesthetic value (Gaut 2007: 9). This paper argues that the assumption that artworks have intrinsic ethical value is problematic at least in regards to a significant subset of works: fictional artworks. I argue that, insofar as their ethical value emerges only from attitudes attributable to (...) actual agents, fictional artworks only have extrinsic ethical value. I show that what is at stake for interactionism is whether ethical judgements concerning artists’ attitudes in a context, rather than manifested attitudes, are ever aesthetically relevant. I conclude that, without buying into extreme actual intentionalism, a still controversial theory of interpretation that ties artworks’ meaning to actual artists, interactionism fails to show that ethical flaws/merits are aesthetic flaws/merits.

Advocates of the ethical criticism of art claim that works' ethical defects or merits have an impact on their aesthetic value. Against ethical critics, autonomists claim that moral criteria should not be part of the considerations when evaluating works of art as art. Autonomism refers to the view that an artwork's aesthetic value is independent from its ethical value. The purpose of this paper is to examine how autonomism has been defended in the contemporary discussion in analytic aesthetics. I present (...) three versions of autonomism: Richard Posner's radical autonomism, James C. Anderson and Jeffrey T. Dean, and James Harold's moderate autonomism, and Francisca Pérez Carreño's robust autonomism. I argue that robust autonomism offers a stronger argument against the ethical critic. However, I point to some difficulties for Pérez Carreño's account and conclude by suggesting how further work in autonomism might go around them. (shrink)

Through cultural transmission, repeated learning by new individuals transforms cultural information, which tends to become increasingly compressible . Existing diffusion chain studies include in their design two processes that could be responsible for this tendency: learning and reproducing . This paper manipulates the presence of learning in a simple iterated drawing design experiment. We find that learning seems to be the causal factor behind the increase in compressibility observed in the transmitted information, while reproducing is a source of random heritable (...) innovations. Only a theory invoking these two aspects of cultural learning will be able to explain human culture's fundamental balance between stability and innovation. (shrink)

Orphan drug policy often gives ‘special treatment’ to rare diseases, by giving additional priority or making exceptions to specific drugs, based on the rarity of the conditions they aim to treat. This essay argues that the goal of orphan drug policy should be to make prevalence irrelevant to funding decisions. It aims to demonstrate that it is severity, not prevalence, which drives our judgments that important claims are being overlooked when treatments for severe rare diseases are not funded. It shows (...) that prioritising severity avoids problems caused by prioritising rarity, and that it is compatible with a range of normative frameworks. The implications of a severity-based view for drug development are then derived. The severity-based view also accounts for what is wrong with how the current system of drug development unfairly neglects common diseases that burden the developing world. Lastly, the implications of a severity-based view for current orphan drug policies are discussed. There are no data in this work. (shrink)

Blockchain is an open digital ledger technology that has the capability of significantly altering the way that people operations operate in organizations. This research takes a first step in proposing several ways in which the blockchain technology can be used to improve current organizational practices, while also considering the ethical implications. Specifically, the paper examines the role that blockchain technology plays in three primary areas of people operations: entry to the organization, intraorganizational processes, and exit. In each section, the paper (...) reviews the ethical implications from the lenses of virtue ethics, utilitarianism, deontology and contractarianism. The paper concludes that in whole the implementation of blockchain technology in people operations processes can create a more ethical work environment. However, careful implementation is necessary and requires extensive examination of ethical implications in advance. (shrink)

Invertebrate animals are usually seen as a kind of “aliens” which do not deserve any moral consideration. However, there is a growing amount of evidenceindicating that many of them do have the capacity to experience pain. The samecriteria that are usually applied in order to infer that vertebrates are sentient beings (behavioral response, learning capacity, memory, a certain specific neurophysiological structure…) lead to the idea that many invertebrates aresentient as well. Therefore, under the skeptical premise that we have no directevidence (...) of the experience of pain in vertebrates, we are forced to hold that itexists in both vertebrates and invertebrates.

Aesthetic evaluations of human bodies have important implications for moral recognition and for individuals’ access to social and material goods. Unfortunately, there is a widespread aesthetic disregard for non-white bodies. Aesthetic evaluations depend on the aesthetic properties we regard objects as having. And it is widely agreed that aesthetic properties are directly accessed in our experience of aesthetic objects. How, then, might we explain aesthetic evaluations that systematically favour features associated with white identity? Critical race philosophers, like Alia Al-Saji, Mariana (...) Ortega, Paul C. Taylor, and George Yancy, argue that this is because the perception of racialized bodies is affected by the social structures in which they are appreciated. The aim of this paper is to propose how social structures can affect aesthetic perception. I argue that mental imagery acquired through the interaction with aesthetic phenomena structures the perception of non-aesthetic properties of bodies, so that aesthetic properties consistent with racist stereotypes are attributed to individuals.

This article examines the role of the Spanish Atomic Forum as the representative of the nuclear sector in the public arena during the golden years of the nuclear power industry from the 1960s to 1970s. It focuses on the public image concerns of the Spanish nuclear lobby and the subsequent information campaigns launched during the late 1970s to counteract demonstrations by the growing and heterogeneous anti-nuclear movement. The role of advocacy of nuclear energy by the Atomic Forum was similar to (...) that in other countries, but the situation in Spain had some distinguishing features. Anti-nuclear protest in Spain peaked in 1978 paralleling the debates of a new National Energy Plan in Congress, whose first draft had envisaged a massive nuclearization of the country. We show how the approval of the Plan in July 1979, with a significant reduction in the nuclear energy component, was influenced by the anti-nuclear protest movements in Spain. Despite the efforts of the Spanish Atomic Forum to counter its message, the anti-nuclear movement was strengthened by reactions to the Three Mile Island accident in March 1979. (shrink)

This book seeks to arrive at a better understanding of the relationships between the objective and subjective aspects of time. It discusses the existence of fluent time, a controversial concept in many areas, from philosophy to physics. Fluent time is understood as directional time with a past, a present, and a future. We experience fluent time in our lives and we adopt a temporal perspective in our ways of knowing and acting. Nevertheless, the existence of fluent time has been debated (...) for both philosophical and scientific reasons, thus creating a rift between the subjective and objective aspects of time. Starting from the basic notion of points of view, or perspectives, this book explores the relationships between objective or external time, as it has been conceptualized by science, and subjective or internal time, which is involved in our lived experiences. It establishes a general framework encompassing the nature, structure and mode of existence of points of view, in which the objective and subjective aspects of time can be integrated. The book mainly addresses researchers and postgraduates in philosophy and logic. Additionally, it offers inspiration for physicists and computer scientists involved in the modeling and simulation of complex behaviors for which the representation of internal time should be considered together with the notion of objective, external time.

This article examines what constitutes an ethical flaw in artworks and asks which ethical flaws are relevant in determining works. ethical and aesthetic values.

I identify two different types of ethical defects in artworks, fictional and actual, and argue that this (...) distinction has important consequences for debates surrounding the ethical value of works of fiction.

It has been pointed out that Sensorimotor Enactivism, a theory that claims that perception is enacted and brought about by movement, says very little about the neural mechanisms that enable perception. For the proponents of the predictive approach to Sensorimotor Enactivism, this is a challenge that can be met by introducing predictive processing into the picture. However, the compatibility between these theories is not straightforward. Firstly, because they seem to differ in their stand towards representations: while Sensorimotor Enactivism is said (...) to belong to the non-representational wing of cognitive science, predictive processing has a representational profile. And secondly, because they exhibit different explanatory strategies: while Sensorimotor Enactivism prioritizes the interactions of the embodied agent, predictive processing has internalist commitments. The aim of this paper is to address these concerns and show that a predictive approach to Sensorimotor Enactivism is viable. More specifically, I focus on the Free-Energy approach, a theory that falls within the ballpark of predictive processing. In this paper I argue for the following claims. I argue that both Sensorimotor Enactivism and the Free-Energy approach may be understood for some systems in representational terms. The non-representational reading of Sensorimotor Enactivism is not mandatory and neither is the representational reading of the Free-Energy approach. Sensorimotor Enactivism is, in this respect, compatible with both representational and non-representational interpretations of the FEA. So, the position towards representations of these frameworks should not stand in the way of a predictive approach to Sensorimotor Enactivism. I also show that the Free-Energy approach allows for an account that prioritizes the interaction of the embodied agent with the environment. This is the explanatory strategy followed by Sensorimotor Enactivism. To justify this strategy and following other proponents of Sensorimotor Enactivism, I argue that by referring to the interactions of the embodied agent a better account of the phenomena in question is provided. On this basis, I claim that Sensorimotor Enactivism and the Free-Energy approach are compatible in what concerns their explanatory strategy as well. Thus, making the case for the viability of the predictive approach to Sensorimotor Enactivism. (shrink)

Recent years have witnessed an escalation in corporate social reporting (CSR) by UK companies (Gray, Kouhy and Lavers 1995). Whilst some elements of CSR reporting are required by law, much of it represents voluntary reporting.

It specifically asks whether companies are primarily motivated by the strategic need to manage their reputation (...) and legitimacy rather than by the recognition of their ethical accountability, which is the stated purpose of reports produced by cutting edge companies (Clarke 1998).

ResumenEn el marco intelectual del Renacimiento hubo una serie de pensadores que se mostraron disconformes con el aristotelismo dominante. La variedad de sus posturas así como lo distinto de sus posicionamientos filosóficos ha podido actuar como obstáculo para poder ver las similitudes que, en torno a la crítica aristotélica, presentan. El caso de Juan Luis Vives y de Gianfrancesco Pico puede resultar paradigmático, a estos se suma con fuerza Francisco Sánchez, quien dedicó una parte importante de su obra Quod nihil (...) scitur a criticar a Aristóteles, aunque más aún a sus comentaristas.Palabras claveFilosofía del Renacimiento, Francisco Sánchez, Juan Luis Vives, Gianfrancesco Pico, aristotelismo, historia de la filosofía.AbstractIn the intellectual frame of the Renaissance, there were some thinkers who did not agree with the Aristotelism prevailing at the time. The variety of their philosophical positions and opinions may have been an obstacle for an approach to their similarities regarding the Aristotelian critic.

In spite of the considerable development of research in the fields of business ethics and family business, a comprehensive review and integration of the area where both disciplines intersect has not been undertaken so far. This paper aims at contributing to the call for more research on family business ethics by answering the following research questions: What is the status of the current research at the intersection of business ethics and family business? Why and how do family firms differ from (...) non-family firms regarding business ethics? And, what are the key directions for further research? To answer these questions, this study combines a systematic approach for the selection of articles, resulting in a sample of 31 articles over 35 years, with a narrative review to analyze the literature. This paper finds that research on family business ethics is scarce but increasing and that family firms are considerably different from non-family firms regarding ethical issues. Particular stakeholders, goals, relationships, and practices are found to be the forces behind the peculiarity of family business ethics. Ultimately, research development on family business ethics is encouraged and future research directions flowing from the key findings and reflections of this review are provided. (shrink)

Como puede leerse en los Nouveaux essais, Leibniz se proclamaba a sí mismo como seguidor de Platón.

This paper examines folk theories of algorithmic recommendations on Spotify in order to make visible the cultural specificities of data assemblages in the global South. The study was conducted in Costa Rica and draws on triangulated data from 30 interviews, 4 focus groups with 22 users, and the study of “rich pictures” made by individuals to graphically represent their understanding of algorithmic recommendations. We found two main folk theories: one that personifies Spotify and another one that envisions it as a (...) system full of resources. Whereas the first theory emphasizes local conceptions of social relations to make sense of algorithms, the second one stresses the role of algorithms in providing a global experience of music and technology. We analyze why people espouse either one of these theories and how these theories provide users with resources to enact different modalities of power and resistance in relation to recommendation algorithms. We argue that folk theories thus offer a productive way to broaden understanding of what agency means in relation to algorithms. (shrink)

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)

Scholars in the humanities and social sciences have turned to ethics to theorize politics in what seems to be an increasingly depoliticized age. Yet the move toward ethics has obscured the ongoing value of political responsibility and the vibrant life it represents as an effective response to power. Sounding the alarm for those who care about robust forms of civic engagement, this book fights for a new conception of political responsibility that meets the challenges of today's democratic practice. Antonio Y. (...) Vázquez-Arroyo forcefully argues against the notion that modern predicaments of power can only be addressed ethically or philosophically through pristine concepts that operate outside of the political realm. By returning to the political, the individual is reintroduced to the binding principles of participatory democracy and the burdens of acting and thinking as a member of a collective. Vázquez-Arroyo historicizes the ethical turn to better understand its ascendence and reworks Adorno's dialectic of responsibility to reassert the political in contemporary thought and theory.

We provide a new interpretation of Zeno’s Paradox of Measure that begins by giving a substantive account, drawn from Aristotle’s text, of the fact that points lack magnitude. The main elements of this account are (1) the Axiom of Archimedes which states that there are no infinitesimal magnitudes, and (2) the principle that all assignments of magnitude, or lack thereof, must be grounded in the magnitude of line segments, the primary objects to which the notion of linear magnitude applies. Armed (...) with this account, we are ineluctably driven to introduce a highly constructive notion of (outer) measure based exclusively on the total magnitude of potentially infinite collections of line segments. The Paradox of Measure then consists in the proof that every finite or potentially infinite collection of points lacks magnitude with respect to this notion of measure. We observe that the Paradox of Measure, thus understood, troubled analysts into the 1880’s, despite their knowledge that the linear continuum is uncountable. The Paradox was ultimately resolved by Borel in his thesis of 1893, as a corollary to his celebrated result that every countable open cover of a closed line segment has a finite sub-cover, a result he later called the “First Fundamental Theorem of Measure Theory.” This achievement of Borel has not been sufficiently appreciated. We conclude with a metamathematical analysis of the resolution of the paradox made possible by recent results in reverse mathematics. (shrink)
