Authors: Page Álvaro Felipe , Cáceres Cáceres Magda Liliana
Published: November 2019

En este trabajo se presentan los resultados de un estudio experimental para la descripción de las trayectorias descritas por el eje instantáneo de rotación (EIR) toracohumeral para movimientos cíclicos de elevación-descenso. Se ha desarrollado una técnica de análisis de movimientos mediante videofotogrametría que permite la medida del EIR del movimiento relativo húmero tórax con un error inferior a 1 cm y de forma muy reproducible [1,2]. Esto permite registrar el movimiento continuo del EIR como un axoide, cuyo desplazamiento mediolateral está relacionado con las velocidades de rotación de las articulaciones esternoclavicular, acromioclavicular y glenohumeral, y cuya posición vertical se asocia a la elevación de articulación glenohumeral [3] Se ha realizado un estudio con 45 sujetos sanos y 15 sujetos con patologías del hombro, analizando el movimiento cíclico de elevación-descenso del húmero en los planos frontal y escapular. La ubicación y forma de los axoides es sensible a los efectos de la carga y del estado funcional del sujeto. Así el efecto de la carga se manifiesta en un desplazamiento medial de la trayectoria del EIR, asociado a un movimiento más acusado de las articulaciones esternoclavicular, acromioclavicular frente al movimiento sin carga. Por otra parte, el efecto de la patología afecta a la trayectoria del EIR sólo a partir de cierto nivel de limitación funcional. Los patrones correspondientes a pacientes con limitaciones leves no muestran diferencias importantes frente a los sujetos sanos. Los resultados obtenidos muestran que el EIR puede ser de utilidad en la valoración funcional biomecánica del hombro, al ofrecer información sobre la coordinación de las diferentes articulaciones que lo constituyen REFERENCIAS [1]  A.Page, J.A.

Published: November 2019

La neurocirugía robótica está sufriendo profundos cambios en los últimos tiempos, fruto principalmente de los avances en las técnicas de imagen médica (TAC, MRI, f-MRI o DTI), lo que permite una mejor planificación de la operación a realizar. La neurocirugía mínimamente invasiva se ve beneficiada de estos avances. Sin embargo, quedan problemas a resolver en la transferencia del plan de trabajo pre-planificado a la realidad intra-operatoria, debido a la naturaleza no-lineal de los tejidos deformables involucrados. Uno de estos problemas es el brain-shift, o desplazamiento de la materia cerebral fruto del cambio de presión interior al practicar la craneotomía y de los propios procesos quirúrgicos, y que produce una pérdida de referencia entre los volúmenes de imagen de neurocirugía adquiridos antes de la cirugía.En este trabajo se presenta un sistema de imagen médica por microondas para detección y corrección del problema de brain-shift en operaciones de tumores cerebrales. Se presenta el sistema desarrollado, los componentes electrónicos de alta frecuencia y control que forman parte del mismo y el software que permite obtener las imágenes. El sistema de antenas permite obtener en tiempo real la localización de los puntos de control del modelo de deformaciones para la visualización utilizando realidad aumentada.
Efecto de interacción entre el paradigma de presentación y el conjunto de estímulos en un teclado virtual controlado a través de una interfaz cerebro-ordenador basada en P300

Published: November 2019

Anteriores propuestas en el manejo de un teclado virtual a través de una interfaz cerebro-ordenador basada en P300 han mostrado una mejora mediante el uso de imágenes en lugar de letras como estímulos objetivo en un paradigma de fila-columna (RCP, row-column paradigm). Sin embargo, el RCP podría no ser adecuado para aquellos pacientes con ausencia de movilidad ocular. Para resolver esto, el paradigma de la presentación visual en serie rápida (RSVP, rapid serial visual presentation), que presenta los estímulos ubicados en la misma posición, ha sido propuesto en estudios anteriores. Por lo tanto, el objetivo del presente trabajo es evaluar si un conjunto de imágenes alternativas, que mejoraron el rendimiento en RCP, podrían mejorar el rendimiento también en RSVP. Los 16 participantes del estudio controlaron cuatro condiciones en una tarea de calibración y otra de escritura: i) letras en RCP, ii) imágenes en RCP, iii) letras en RSVP e iv) imágenes en RSVP. Los resultados mostraron que el efecto de mejora dado por las imágenes fue mayor en el paradigma RCP que en RSVP. Por lo tanto, este trabajo prueba que las mejoras relacionadas con estímulos alternativos bajo RCP pueden no ofrecer los mismos resultados en RSVP.
La estimulación mecánica aferente no reduce sistemáticamente el temblor de pacientes con temblor esencial.

Published: November 2019

El temblor esencial (ET) es una uno de los desórdenes motrices más prevalentes en adultos, con tratamientos poco efectivos en la mitad de los casos. En este documento, estudiamos si la estimulación mecánica aferente puede reducir el temblor en pacientes de ET al estimular selectivamente las vías aferentes. Para ello, hemos diseñado una plataforma que permite estimular la mano y el antebrazo del paciente utilizando actuadores piezoeléctricos mientras monitorizamos el temblor mediante sensores inerciales. Hemos analizado el efecto de cuatro estrategias de estimulación, incluyendo estimulación a frecuencia constante y variable, en 18 pacientes de ET. A pesar de que no existe una clara respuesta a la vibración ante las diferentes estrategias, en la mayoría de los casos (50-72%) la estimulación mecánica se asocia a un aumento en la amplitud del temblor. Por el contrario, el temblor se reduce entre el 5 y el 12% de los pacientes. Sin embargo, estos resultados son difíciles de interpretar debido a la variabilidad intrínseca del temblor: durante ensayos de la misma duración, el temblor varió significativamente en el 67% de los pacientes (aumentando en el 45% y disminuyendo en el 22%). Por tanto, la estimulación mecánica de la extremidad no tiene un efecto sistemático en el temblor propio del Temblor Esencial.
Estimación de los esfuerzos generados en el hombro por parte de trabajadores de la industria del automóvil mediante modelos biomecánicos de medidas in situ

Los trabajos lineales en la industria del automóvil involucran riesgos derivados de tareas repetidas y posturas forzadas mantenidas en el tiempo. Si bien, varias son las plataformas y herramientas que intentan evaluar ergonómicamente los puestos de trabajo, como los software de valoración de riesgos REBA y ERGO/IBV, estas herramientas carecen de sensibilidad a la hora de determinar aspectos relacionados con el riesgo de la lesión. Esto ocurre especialmente cuando se introducen nuevas ayudas en los puestos de trabajo, distintas a los métodos habituales, que no están contempladas, como el uso de exoesqueletos. Es por ello que se presenta una metodología para estimar los esfuerzos musculares y articulares asociados al trabajo lineal. Evaluamos, ergo, a 10 trabajadores realizando su trabajo habitual en condiciones reales. Se utiliza un modelo de miembro superior implementado en OpenSim (Saul et al. 2015), al que se le introduce la dinámica de los movimientos medidos con sensores inerciales y con el registro de la señal muscular de cuatro músculos: cara anterior del deltoides, porción superior del trapecio, el erector espinal y el gran dorsal. Los resultados obtenidos muestran una buena consistencia entre las estimaciones musculares registradas y las estimadas por el modelo biomecánico. Estos resultados pueden sentar las bases prácticas para una valoración objetiva del riesgo en el puesto de trabajo con condiciones novedosas tal como el uso de exoesqueletos.
Spatially distributed sensitivity of simulated global groundwater heads and flows to hydraulic conductivity, groundwater recharge, and surface water body parameterization

Published: November 2019

Abstract. In global hydrological models, groundwater storages and flows are generally simulated by linear reservoir models. Recently, the first global gradient-based groundwater models were developed in order to improve the representation of groundwater–surface-water interactions, capillary rise, lateral flows, and human water use impacts. However, the reliability of model outputs is limited by a lack of data and by uncertain model assumptions that are necessary due to the coarse spatial resolution.
The impact of data quality is presented in this study by showing the sensitivity of a groundwater model to changes in the only available global hydraulic conductivity dataset. To better understand the sensitivity of model output to uncertain spatially distributed parameters, we present the first application of a global sensitivity method for a global-scale groundwater model using nearly 2000 steady-state model runs of the global gradient-based groundwater model G3M. By applying the Morris method in a novel domain decomposition approach that identifies global hydrological response units, spatially distributed parameter sensitivities are determined for a computationally expensive model. Results indicate that globally simulated hydraulic heads are equally sensitive to hydraulic conductivity, groundwater recharge, and surface water body elevation, though parameter sensitivities vary regionally. For large areas of the globe, rivers are simulated to be either losing or gaining, depending on the parameter combination, indicating a high uncertainty in simulating the direction of flow between the two compartments. Mountainous and dry regions show a high variance in simulated head due to numerical instabilities of the model, limiting the reliability of computed sensitivities in these regions. This is likely caused by the uncertainty in surface water body elevation. We conclude that maps of spatially distributed sensitivities can help to understand the complex behavior of models that incorporate data with varying spatial uncertainties. The findings support the selection of possible calibration parameters and help to anticipate challenges for a transient coupling of the model.
Sensitivity of the Greenland mass and energy balance to uncertainties in key model parameters
Authors: Zolles Tobias , Born Andreas
Published: November 2019

Abstract. We investigate the sensitivity of a glacier surface mass and energy balance model using a variance based analysis, for two distinct periods of the last glacial cycle: present day climate and the Last Glacial Maximum (LGM). The results can be summarized in three major findings: The sensitivity towards individual model parameters and parameterizations is neither invariant in space nor in time. The model is most sensitive to uncertainty related to down-welling long-wave radiation. Turbulent latent heat flux has a sizable contribution to the surface mass balance uncertainty in central Greenland today and over the entire ice sheet during the cold climate of the LGM, in spite of its low impact on the overall surface mass balance of the Greenland ice sheet in modern climate. We conclude that quantifying the model sensitivity is very helpful for the subsequent tuning of free model parameters, because it clarifies the relative importance of individual parameters and highlights interactions between them that need to be considered.
Intermittency of Arctic-midlatitude teleconnections: stratospheric pathway between autumn sea ice and the winter NAO
Authors: Siew Peter Yu Feng , Li Camille , Sobolowski Stefan Pieter , King Martin Peter
Published: November 2019

Abstract. There is an observed relationship linking Arctic sea ice conditions in autumn to midlatitude weather the following winter. Of interest in this study is a hypothesized stratospheric pathway whereby reduced sea ice in the Barents-Kara Seas enhances upward wave activity and wave-breaking in the stratosphere, leading to a weakening of the polar vortex and a transition of the North Atlantic Oscillation (NAO) to its negative phase. A Causal Effect Networks (CEN) framework is used to explore the stratospheric pathway between late autumn Barents-Kara sea ice and the February NAO, focusing on its seasonal evolution, timescale-dependence, and robustness. Results indicate that the pathway is statistically detectable and has been relatively “active” over the 39-year observational period used here, explaining approximately 26 % of the interannual variability in the February NAO. However, a bootstrap-based resampling test reveals that the pathway is highly intermittent: the full stratospheric pathway appears in only 15 % of the sample populations derived from observations, with individual causal linkages ranging from 44 to 85 % in occurrence rates. The pathway’s intermittency is consistent with the weak signal-to-noise ratio of the atmospheric response to Arctic sea ice variability in modelling experiments, and suggests that Arctic-midlatitude teleconnections might be favoured in certain background states. On shorter time scales, the CEN detects two-way interactions between Barents-Kara sea ice and the midlatitude circulation that indicate a role for synoptic variability associated with blocking over the Urals region and moist air intrusions from the Euro-Atlantic sector. This synoptic variability has the potential to interfere with the stratospheric pathway, thereby contributing to its intermittency. This study helps quantify the robustness of causal linkages within the stratospheric pathway, and provides insight into which linkages are most subject to sampling issues within the relatively short observational record. Overall, the results should help guide the analysis and design of ensemble modelling experiments required to improve physical understanding of Arctic-midlatitude teleconnections.
An Investigation of Feminine Personal Names in Beni Sakhr Tribe of Jordan: A Sociolinguistic Study

Published: November 2019

The research paper examined the feminine personal names within Beni Sakhr tribe, which inhabits the Jordanian central desert with the aim of pointing out the sociolinguistic implications of the names, and the differences in naming practices throughout three generations (grandmothers, mothers. daughters). For this reason, 300 names of female school students in the elementary stage were obtained from Almwaqqar Directorate of Education alongside their mothers and grandmothers. Analysis of a total number of 900 names, divided equally between the three categories, revealed that 69 % of the grandmothers' names are Bedouin-exclusive names opposed to (9%) and only (2%) of the mothers and daughters’ names respectively. Grandmothers’ names derive mainly from the needs of the dwellers of desert regions, the severe conditions they experienced, and the social values of the Jordanian nomadic tribes. Only 9 (3%) names of a religious background are identified in this category compared to 42 (14%) in the mothers’ names and 25 (8.3%) in the daughters’ names. In general, the paper finds evidence to suggest that the change in the lifestyle of Beni Sakhr tribe does influence the naming practice in this community.

Published: November 2019

Internationalization represents an obligatory path for firms in order to compete and survive in the current competitive environment. However, many enterprises, especially the SMEs, sometimes lack the necessary resources to grow and succeed in international markets. Several authors argue that SMEs constantly need to create, adapt and reconfigure their relationships and network resources to remain competitive in an international environment, that is, they need to develop dynamic capabilities. The aim of this paper is to analyze the international growth of gradual global SMEs by adopting the dynamic capabilities framework. Through the case study of a firm from South Italy, this paper aims to analyze the role played by dynamic capabilities in the growth and success of a gradual global SME in international markets. The results show that the capabilities to perceive opportunities and threats in the international context, to seize opportunities through adaptation, reactivity and reconfiguration, have been fundamental for the international success of the company analyzed.

Although apparel fit and size has been investigated in previous research, it is yet to be test to understand apparel consumer behavior in ecommerce and their concern with being unable to try on clothing or imagine fit/size before making purchase decision. Therefore, the purpose of this exploratory study was to examine the relationship between concern with inability to try on clothing and imagining size/fit in online context and their relationship with demographic variables and previous experience. While these study findings indicated no significant relationship between demographic variables and apparel online shopping orientation, other psychographic variable should be explored.

De kwaliteit van beleidsdoorlichtingen

Voor doeltreffend en doelmatig beleid is het essentieel om verantwoording af te leggen over de gemaakte keuzes en te leren van de lessen uit het verleden. Om dit te stimuleren verplicht de Regeling Periodiek Evaluatieonderzoek (RPE) de rijksoverheid om periodiek beleidsdoorlichtingen te (laten) verrichten. Een beleidsdoorlichting bundelt alle beschikbare kennis over de doeltreffendheid en doelmatigheid van een volledig beleidsterrein over een bepaalde periode. Daartoe worden alle tussentijds uitgevoerde beleidsevaluaties bestudeerd.

Dit artikel beschrijft de kwaliteit van beleidsdoorlichtingen. Het artikel is gebaseerd op onderzoek van SEO Economisch Onderzoek in opdracht van het Ministerie van Financiën. Het gebruik van beleidsdoorlichtingen valt buiten de scope van dit artikel.

Uit een steekproef van 49 beleidsdoorlichtingen blijkt dat de doeltreffendheid en doelmatigheid van het gevoerd beleid vaak niet goed in beeld komen. Dit komt onder meer omdat er te weinig goed evaluatieonderzoek wordt uitgevoerd en omdat beleidsdoelstellingen met enige regelmaat worden aangepast. Het gevolg hiervan is dat uitspraken over de doeltreffendheid van beleid meestal niet stevig onderbouwd zijn en de doelmatigheid van beleid onderbelicht blijft. Dit maakt het minder goed mogelijk om lessen uit het verleden te trekken.

Er is ruimte voor verbetering. Zo kan (1) het lerend vermogen van ministeries intern versterkt worden, (2) kunnen departementen hun beleidsevaluaties systematischer uitvoeren om volledigheid te waarborgen, (3) dient er ex ante te worden vastgesteld hoe de doeltreffendheid en doelmatigheid van beleidsmaatregelen ex post (causaal) kunnen worden geëvalueerd, (4) kan de onafhankelijk deskundige die bij beleidsdoorlichtingen wordt ingezet tevens de kwaliteit van het beschikbare evaluatiemateriaal vaststellen, en (5) kan worden overwogen om beleidsdoorlichtingen strategisch te plannen aan het eind van een kabinetsperiode. Op deze manier neemt de toegevoegde waarde van de beleidsdoorlichting toe.

Differentiating dysplasia markers in Barrette sophagus and adenocarcinoma
Authors: Mor Adrian , Kobus Krzysztof , Leszczyńska Urszula , Reszeć Joanna
Published: November 2019

Barrett’s esophagus (BE) is the only known precursor of esophageal adenocarcinoma (EAC). This precancerous lesion can transform into low-grade and high-grade dysplasia, which may develop in the EAC. Therefore, the issues of dysplasia detection and monitoring and early diagnostics for the presence of EAC foci are extremely important factors in the surveillance of patients with BE progression. Histopathological examinations are regarded as the gold standard in the BE progression evaluation. They posses a large clinical utility in the identification of dysplasia and cancer risk stratification in patients with the BE. However, this method is a very subjective, and is heavily dependent on the knowledge and experience of the person conducting it. Therefore, it seems to be important to implement in the BE progression diagnostics sensitive and specific biomarkers that could be used as complementary tests. They could improve detection, stratification and monitoring of the progression of BE and the detection of the EAC early stages. Literature data concerning markers distinguishing between different stages of Barrett’s-related dysplasia and cancer is very scarce. In this article there we collected and characterized the most important data. Apart from this, there is a fairly large group of proteins and genes. Their expression levels allow for the detection of changes during the development of the BE progression. No studies have been carried out yet for their usefulness in differentiating between types of BE-related dysplasia and EAC, but we know that some of them could be useful as auxiliary markers differentiating between different stages of dysplasia and EAC. The article discusses those with the greatest potential.
High performance computing architectures analysis for gene networks inference
Authors: Marco Anderson , Gazziro Mario , Martins Jr David
Published: November 2019

Modeling and inference of biological systems are an important field in computer science, presenting strong interdisciplinary aspects. In this context, the inference of gene regulatory networks and the analysis of their dynamics generated by their transition functions are important issues that demand substantial computational power. Because the algorithms that return the optimal solution have an exponential time cost, such algorithms only work for gene networks with only dozens of genes. However realistic gene networks present hundreds to thousands of genes, with some genes being hubs, i.e., their number of predictor genes are usually much higher than average. Therefore there is a need to develop ways to speed up the gene networks inference. This paper presents a benchmark involving GPUs and FPGAs to infer gene networks, analysing processing time, hardware cost acquisition, energy consumption and programming complexity. Overall Titan XP GPU achieved the best performance, but with a large cost regarding acquisition price when compared to R9 Nano GPU and DE1-SOC FPGA. In its turn, R9 Nano GPU presented the best cost-benefit regarding performance, acquisition price, energy consumption, and programming complexity, although DE1-SOC FPGA presented much smaller energy consumption.
ViViD Cuckoo Hash: Fast Cuckoo Table Building in SIMD
Authors: Cristo Flaviene de , Almeida Eduardo de , Alves Marco
Published: November 2019

Hash Tables play a lead role in modern databases systems during the execution of joins, grouping, indexing, removal of duplicates, and accelerating point queries. In this paper, we focus on Cuckoo Hash, a technique to deal with collisions guaranteeing that data is retrieved with at most two memory access in the worst case. However, building the Cuckoo Table with the current scalar methods is inefficient when treating the eviction of the colliding keys. We propose a Vertically Vectorized data-dependent method to build Cuckoo Tables - ViViD Cuckoo Hash. Our method exploits data parallelism with AVX-512 SIMD instructions and transforms control dependencies into data dependencies to make the build process faster with an overall reduction in response time by 90% compared to the scalar Cuckoo Hash.

Neste contexto, contêineres representam uma tecnologia de virtualização que tentam resolver essas demandas. Dessa forma, avaliar seu desempenho é fundamental para sua adoção em larga escala. Este artigo investiga, através de um experimento, o desempenho em termos de tempo de resposta de volumes para contêineres Docker Volume e NFS, visto que tal análise não foi encontrada nos trabalhos relacionados. Os resultados mostram que há diferença significativa entre todos os testes com o Docker Volume e o NFS assíncrono e alguns diferenças significativas com o NFS síncrono.
A Hermeneutic Understanding of Dialogue as a Tool for Global Peace
Authors: Chukwuokolo J. Chidozie , Jeko Victor O. ,   Polish Academy of Sciences
Published: November 2019

The problem of threat to international politics and global peace has undermined the effectiveness of the power of dialogue. The world seems to be in the condition of will to power derivable from the mutually assured destructive (MAD) tendencies. Is it possible to extend global peace? How can this be achieved? In this paper, we posit that dialogue is a fundamental medium for conflict resolution and peaceful coexistence in a diverse world. We contend that monologue in international politics understood in terms of might is right undermines the effectiveness of dialogue and often leads to violent conflicts within and between countries. Our world today is at a crossroads. Dialogue, however, foregrounds the medium of conflict resolution and the social consciousness of human communication. We present a hermeneutic understanding of dialogue that follows from relevant works of Hans Georg Gadamer and Jűrgen Habermas. This paper espouses the power of dialogue as a basis for the normative foundation of an emancipated social global order. The dialogical sequence has a cobweb of social interconnectedness and the ethics of global peace. We present a literal and philosophical understanding of dialogue and a contextual understanding of dialogue within the hermeneutic tradition.
The Order of Body
Authors: Krupecka Iwona ,   Polish Academy of Sciences
Published: November 2019

This text focuses on the possibility of acquiring universal knowledge (especially about values) by individual subjective consciousness as determined both corporeally and culturally. Along with the appearance of the “question” of the cultural Other (and with the cultural relativism as its other side) the attempts of European philosophers to establish a kind of a universal sphere—intellectual basis for an intercultural dialogue—became more intensive, but still often limited by their relation to the values and ideas of the only one culture. In other words, the attempts to search the community of human kind in an intellectual sphere often led to the universality being the “universalized particularity” (Wallerstein), maintained by the empty signifiers (Laclau). But there is also another philosophical tradition, in which the “universality” of ideas, concepts or values is being perceived as a quasi-universality or pluri-versality, mediated by human organic and cultural interactions, and is being derived rather from “beyond”—from the condition of embodiment—than from “above,” the pure intellectual cognition. I focus on three instances of moving from the order of body towards the quasi-universal values: on Bartolomé de Las Casas’s posing a problem of the universal values in the context of intercultural dialogue, on Michel de Montaigne’s reflections on human nature and Walter Mignolo’s naturalistic foundation of the comparative studies. I chose these examples, because they offer a clear and expressed attempt to reformulate the very idea of possible universality in the context of the desired intercultural dialogue, but within the optics of the embodied subjectivities.
The Contemporary Antithesis between Art and Beauty
Authors: Hanza Kathia ,   Polish Academy of Sciences
Published: November 2019

This article examines the antecedents and background of the antithesis between art and beauty. It also considers if this confrontation, typical in modern aesthetics, provides necessary conceptual categories to comprehend the situation of art in the communication era, characteristic of a generalised aesthetisation. Departing from the ideas posed by Yves Michaud, Mateu Cabot, Didi-Huberman and Mario Perniola, the author dismantles the false opposition between art and beauty; she proposes a strategy to avoid an antithetical position and exhorts the readers to recover a different experience from beauty.
Globalization and the Question of African Cultural Identity
Authors: Ọládèbóa Ọmọ́táyọ̀ Ayọ̀dèjì ,   Polish Academy of Sciences
Published: November 2019

This paper engages in the debate between cultural modernists and cultural traditionalists concerning the importance of cultural fidelity as faced by African people via globalization and its alleged homogenizing tendency. Central to this debate is the issue of cultural truths and its use, that is, development. The paper therefore argues that African peoples do not need to “essentialize” their cultures. This is because the “truths about reality” with which they intend to employ in this quest for development are not exclusive to any particular cultural society. The implication of the foregoing is the paper’s insistence that Africans adopt a complementarist attitude in their determination for cultural fidelity. It maintains that this attitude will make Africans avail themselves of ideas from elsewhere. Ultimately, the paper posits that this new disposition of Africans to their cultures and those of non-African societies will set her beleaguered states on a solid developmental trajectory.

This paper offers a sketch of the complicated conflicts which arise—and metastasize seemingly daily—in the era of Big Data. Given the public’s ubiquitous-yet-ostensibly-voluntary data surrender, and industry’s ubiquitous-yet-ostensibly-anodyne collection of the same, inaction is not an option for any near-just society. By revisiting the philosophical basis for Panoptic apparatus (via Bentham and Foucault), sketching the tumultuous history of US contract law trying to protect the public from itself (from Lochner to Carpenter), and comparing existing industry codes for similarly-situated—read: terrifyingly invasive—fields (e.g., physicians, therapists, attorneys, accountants), the paper will provide a preliminary framework for identifying and confronting the galaxy of problems associated with data analytics.
Healing in the Chthulucene
Authors: Dev Laura ,   Polish Academy of Sciences
Published: November 2019

The term “Anthropocene” is frequently used to refer to the present planetary epoch, characterized by a geological signature of human activities, which have led to global ecological crises. This paper probes at what it means to be human on earth now, using healing as a concept to orient humanity in relation to other species, and particularly medicinal plants. Donna Haraway’s concept of the “Chthulucene” is used as an alternate lens to the Anthropocene, which highlights the inextricable linkages between humans and other-than-human species. Healing can be viewed as a type of embodied orientation or engagement with the world, which has the potential to reach across boundaries of the skin, blur distinctions between self and other, and allow for both transpersonal and trans-species reconciliation. I focus my attention on Indigenous Shipibo healing rituals, and Shipibo concepts of healing that integrate humans within the ecosystem, and traverse species boundaries through communication with and embodiment of plant spirits. These healing rituals offer ways of coming into being within an ecology of selves—both internal and external, human and non-human—through listening and lending voice. I explore the potential for healing and ritual to work as a form of porous resistance through the internal blurring of binaries and hierarchical structures.
My Data Is Mine

In August 2018, several European consumer associations have launched a lawsuit against Facebook arguing that “My data is mine,” but chose not to boycott the social network in its publicity campaign. The DECO FAQ list reveals why associations did not call for a boycott: they chose instead to use Facebook to disseminate information and to answer questions consumers might have. The argument presented by the associations confronts us with intricate questions concerning the nature of civil society, mainly with respect to the linkage between the market and the public sphere. Generally, critical theorists think that the realms of necessity and freedom are found incompatible with one another. The public sphere is considered as the realm of pure freedom where citizens deliberate matters concerning the destiny of the polis. The civil society is concerned with profit and with providing for material needs. The present paper approaches these questions by considering the nature of institutional configurations of contemporary digital capitalism and, also, the kind of interactions among social agents that act inside it. Are corporate digital networks (Facebook, YouTube, etc.) permeable enough to communicative rationality to make us believe that they can host a culture of convergence and cooperative interaction among social agents such that can aspire to a rational public sphere? To answer those queries, this paper develops a) a literature review on the contradictions of modern contemporary cognitive capitalism; b) a critical analysis of activists’ statements against the use of digital networks; c) support for a critical literacy approach that identifies textual structures and contextual frameworks in digital public debate.
Alexa Does Not Care. Should You?
Authors: Kudina Olga ,   Society for Phenomenology and Media
Published: November 2019

This article explores the ethical dimension of digital voice assistants from the angle of postphenomenology and the technological mediation approach, whereby technology plays a mediating role in the human-world relations. Digital voice assistants, such as Amazon Echo’s Alexa or Google’s Home, increasingly form an integral part of everyday life for many people. Powered by Artificial Intelligence and based on voice interaction, voice assistants promise constant accompaniment by answering any questions people might have and even managing the physical space of their homes. However, while accompanying daily lives of people, voice assistants also seamlessly redefine the way people talk, interact and perceive each other. In view of their intentionalities, such as interaction by voice, command-based model of communication and development of attachment, digital voice assistant mediate the norms of interaction beyond their immediate use, the way people perceive themselves, those around and form consequent normative expectations. The article argues that understanding how technologies, such as digital voice assistants, mediate our moral landscape forms an essential part of media literacy in the digital age.
Notes on Media Literacy and Illiteracy
Authors: Majkut Paul ,   Society for Phenomenology and Media
Published: November 2019

As an uncritical theoretical presupposition, the notion of literacy has led to formalistic, bookish philosophy. The constipated philosophical discourse adjudged worthwhile by literati and digirati falls historically into a line of dogmatic argument and counterargument within academic tradition submerged in subjective-idealist solipsism, petit-bourgeois political apologetics, and economic escapism. Careerist generalization of literacy from the ability to read print to include metaphoric uses of the term “literacy” to all media, while comfortably foggy to irrationalists, adds little to our understanding of print or other media except by increasing the gloom that prevails among privileged, neo-liberal pettifoggers.
‘I’ and the First Person Perspective
Authors: Röska-Hardy Louise
Published: November 2019

Do the special features of 'I' have epistemological and metaphysical implications? Many philosophers have thought so. Here I investigate the relation between the first person singular pronoun 'I' and the first person perspective, construed as the perspective of consciousness. First, I discuss the semantics of 'I' as a lexeme of a natural language. The fact that semantic reference and speaker reference always coincide in the case of 'I' is shown to have important consequences: it explains the 'referential guarantees' and the impossibility of 'misidentification' which have seemed so mysterious. Secondly, it is shown that these special features accrue only to actual uses. Consequently, the relation between 'I' and the first person perspective must be explicated within the context of linguistic action. It is then argued that the functioning of 'I' is not to be equated with that of a name, a description or an identifying singular term. Instead, I propose that a use of 'I' indexes a linguistic act with respect to the responsible agent. Thus construed, the use of 'I' in an utterance does more than express the first person perspective, since the first person perspective can be expressed by unmarked, impersonal or zero-pronominalization linguistic forms. I conclude by illustrating this claim with examples from the Wiener Kreis.
The Neo-Kantians and the ‘Logicist’ Definition of Number
Authors: Pulkkinen Jarmo
Published: November 2019

The publication of Russell's The Principles of Mathematics (1903) and Couturat's Les principes des mathematiques (1905) incited several prominent neo-Kantians to make up their mind about the logicist program. In this paper, I shall discuss the critiques presented by the following neo-Kantians: Paul Natorp, Ernst Cassirer and Jonas Cohn. They argued that Russell's attempt to deduce the number concept from the class concept is a petitio principii. Russell replied that the sense in which every object is 'one' must be distinguished from the sense in which 'one' is a number. I claim that Russell was wrong in dismissing the neo-Kantian argument as an elementary logical error. To accept Russell's distinction would be to accept at least part of Russell's logicist program. The expression 'a class with one member' would presuppose the number 'one' only if one simultaneously accepted the analysis which mathematical logic provides for it (the class u has one member when u is not null and 'x and y are us' implies 'x and y are identical'). My point is that the aforementioned analysis provided by mathematical logic was something that the neo-Kantians were not ready to accept.
Reflexive Transparency, Mental Content, and Externalism
Authors: Bernier Paul
Published: November 2019

It has been disputed whether an externalist conception of the individuation of intentional states, such as beliefs and desires, is compatible with self-knowledge, that is, the claim that one's judgments about one's intentional states are non-evidential, non-inferential, and authoritative. I want to argue that these theses are indeed incompatible, notwithstanding an important objection to this incompatibility claim. The worry has been raised that if externalism is true, then for a subject to know, say, that he or she believes that p, the subject would need to know, on the basis of some evidence, the external conditions which determine the belief's content. Thus, externalism would be incompatible with self-knowledge. But many philosophers have accepted an objection suggesting that this worry is mistaken because in order to have a belief one need not know the metaphysical conditions determining its content, even if they are externalist. And thus, the subject's reflexive judgment about the belief would not need to rest on evidence about those external conditions. But this objection rests on a crucial assumption according to which mental content is reflexively transparent in the sense that a subject could not judge that she or he has an intentional state and be mistaken about the content of her or his state, even if the content is externally determined. My main purpose is not reflexively transparent on the assumption of externalism and, thus, self-knowledge and externalism are incompatible.
Nonconceptuality and the Emotions
Authors: Gunther York H.
Published: November 2019

I present an argument for the existence of nonconceptual states. A nonconceptual state is an intentional state which does not require the bearer to possess all requisite concepts in order to represent the state. I frame the debate by outlining two constraints that an argument for nonconceptuality should meet. First, successful argument must present a platitude of concepts and illustrate that there are intentional states which both actually violate this platitude (the empirical constraint) and explain behavior independently of conceptual states (the robustness constraint). This ensures that the notion of nonconceptuality established by the argument will have a significant part in the explanatory arsenal of the intentional psychologist. Secondly, I formulate a platitude of concepts based on the intuition that an individual can only legitimately be held responsible for behavior caused by conceptual states. After qualifying the platitude, I argue that emotional states actually violate the platitude and meet the necessary constraints. Finally, I defend my argument against two challenges: one which denies that the empirical constraint has been met and the other which denies that the robustness constraint has been met. I conclude my discussion with some general remarks on the nature of nonconceptual representation.
