Mitología y magia óptica: sobre la relación entre retrato, espejo y escritura en la poesía de Góngora

Cuando en el contexto de la magia artificialis barroca se apela a modelos míticos para describir y explicar los fenómenos ópticos, esta referencia al mito se integra esencialmente al horizonte histórico-cultural de la emergencia de complejos dispositivos de imágenes ópticas, artísticas, técnicas y científicas. Esto se manifiesta principalmente en la continuidad de tradiciones más antiguas pertenecientes a la magia de la imagen, en las que la idea de la 'vivificación' o 'animación' de imágenes se vincula en múltiples casos con las figuras míticas de los demiurgos-artistas de Prometeo y Pigmalión. Dentro de la literatura barroca española, es notablemente la poesía lírica de Luis de Góngora en la que la alusión a figuraciones de la mitología antigua se vincula con una amplia reflexión acerca de los procesos de transformación histórico-culturales y mediáticos, los cuales afectan también las prácticas literarias y los procesos de representación líricos del autor. En este artículo, dentro del marco de una lectura ejemplar del poema dedicatorio "Hurtas mi vulto", se intentará determinar en qué medida se perfila en el soneto una forma específicamente literaria de recepción del mito, por medio de la cual el texto se inscribe en el horizonte histórico del surgimiento de la 'cultura visual' y de la magia óptica de la temprana Edad ModernaWhen in the context of Baroque magia artificialis, mythical models are called for to describe and explain optical phenomena, this reference to myth is assimilated essentially to the historical-cultural horizon of the emergence of complex devices of optical, artistic, technical, and scientific images. This is shown mainly in the continuity of older traditions belonging to the magic of image, in which the idea of "vivification" or "animation" of images is related in multiple cases to the mythical figures of the demiurge-artists, Prometheus and Pygmalion. Within Baroque Spanish Literature, Luis de Góngora's lyric poetry is that in which the mention of figurations of old mythology remarkably connects with an ample reflection on historical-cultural and mediatic processes of transformation, which also affect the literary practices and the author's lyric processes of representation. Within the frame of an exemplary reading of the celebratory poem "Hurtas mi vulto", this article intends to determine to what extent a specifically literary form of myth reception is outlined in the sonnet, by means of which the text belongs to the historical horizon of the arousing of "visual culture" and of the Early Modern Age optical magic.Centro de Estudios de Teoría y Crítica Literari

Revisiting the birth locations of pulsars B1929+10, B2020+28, and B2021+51

We present new proper motion and parallax measurements obtained with the European VLBI Network (EVN) at 5GHz for the three isolated pulsars B1929+10, B2020+28, and B2021+51. For B1929+10 we combined our data with earlier VLBI measurements and confirm the robustness of the astrometric parameters of this pulsar. For pulsars B2020+28 and B2021+51 our observations indicate that both stars are almost a factor of two closer to the solar system than previously thought, placing them at a distance of 1.39-0.06+0.05 and 1.25-0.17+ 0.14kpc. Using our new astrometry, we simulated the orbits of all three pulsars in the Galactic potential with the aim to confirm or reject previously proposed birth locations. Our observations ultimately rule out a claimed binary origin of B1929+10 and the runaway star ζ Ophiuchi in Upper Scorpius. A putative common binary origin of B2020+28 and B2021+51 in the Cygnus Superbubble is also very unlikely

Precision astrometry of pulsars and other compact radio sources in the globular cluster M15

The globular cluster (GC) M15 (NGC 7078) is host to at least eight pulsars and two low mass X-ray binaries (LMXBs), one of which is also visible in the radio regime. Here we present the results of a multi-epoch global very long baseline interferometry (VLBI) campaign aiming at i) measuring the proper motion of the known compact radio sources; ii) finding and classifying thus far undetected compact radio sources in the GC; and iii) detecting a signature of the putative intermediate mass black hole (IMBH) proposed to reside at the core of M15. We measure the sky motion in right ascension (µa) and declination (µd) of the pulsars M15A and M15C and of the LMXB AC211 to be (µa,µd)M15A = (-0.54 ± 0.14,-4.33 ± 0.25) mas yr-1, (µa,µd)M15C = (-0.75 ± 0.09,-3.52 ± 0.13) mas yr-1, and (µa, µd)AC211 = (-0.46 ± 0.08,-4.31 ± 0.20) mas yr-1, respectively. Based on these measurements we estimate the global proper motion of M15 to be (µa, µd) = (-0.58 ± 0.18,-4.05 ± 0.34) mas yr -1. We detect two previously known but unclassified compact sources within our field of view. Our observations indicate that one them is of extragalactic origin while the other one is a foreground source, quite likely an LMXB. The double neutron star system M15C became fainter during the observations, disappeared for one year and is now observable again-an effect possibly caused by geodetic precession. The LMXB AC211 shows a double lobed structure in one of the observations indicative of an outburst during this campaign. With the inclusion of the last two of a total of seven observations we confirm the upper mass limit for a putative IMBH to be M•< 500 M·. © 2014 ESO

Dementia assessment and management in primary care settings: a survey of current provider practices in the United States.

BACKGROUND:Primary care providers (PCPs) are typically the first to screen and evaluate patients for neurocognitive disorders (NCDs), including mild cognitive impairment and dementia. However, data on PCP attitudes and evaluation and management practices are sparse. Our objective was to quantify perspectives and behaviors of PCPs and neurologists with respect to NCD evaluation and management. METHODS:A cross-sectional survey with 150 PCPs and 50 neurologists in the United States who evaluated more than 10 patients over age 55 per month. The 51-item survey assessed clinical practice characteristics, and confidence, perceived barriers, and typical practices when diagnosing and managing patients with NCDs. RESULTS:PCPs and neurologists reported similar confidence and approaches to general medical care and laboratory testing. Though over half of PCPs performed cognitive screening or referred patients for cognitive testing in over 50% of their patients, only 20% reported high confidence in interpreting results of cognitive tests. PCPs were more likely to order CT scans than MRIs, and only 14% of PCPs reported high confidence interpreting brain imaging findings, compared to 70% of specialists. Only 21% of PCPs were highly confident that they correctly recognized when a patient had an NCD, and only 13% were highly confident in making a specific NCD diagnosis (compared to 72 and 44% for neurologists, both p < 0.001). A quarter of all providers identified lack of familiarity with diagnostic criteria for NCD syndromes as a barrier to clinical practice. CONCLUSIONS:This study demonstrates how PCPs approach diagnosis and management of patients with NCDs, and identified areas for improvement in regards to cognitive testing and neuroimaging. This study also identified all providers' lack of familiarity with published diagnostic criteria for NCD syndromes. These findings may inform the development of new policies and interventions to help providers improve the efficacy of their decision processes and deliver better quality care to patients with NCDs

Empathy and associated influencing factors in occupational therapy students: A cross-sectional study

INTRODUCTION: Empathy, often described as the comprehension of another person's state of mind, enables one to appreciate social environments and anticipate others' behaviour. In occupational therapy, the therapeutic use of self, which is grounded in empathy, is commonly considered essential, as it enables therapists to manage a therapeutic relationship with clients. However, high caseloads, stressors and pressure to perform often impact empathy levels. This study aimed to determine the empathy levels of undergraduate occupational therapy students, as well as factors affecting empathy levels METHOD: A quantitative approach was used, with an observational, cross-sectional study methodology, employing an electronic survey consisting of the Interpersonal Reactivity Index (IRI) and a questionnaire developed by the researchers RESULTS: In total, 112 (response rate 70.4%) students participated in the study. Overall, the students had a satisfactory level of empathy. Of concern, however, was the impact of the Covid-19 pandemic and the lack of clinical fieldwork experience, which possibly contributed to the lower empathy levels observed among second-and third-year students CONCLUSION: From the findings, it is suggested that more attention should be given to empathy, as it plays an integral role in practice with clients, as well as in the training of occupational therapy students Implications for practice The findings suggest the opportunity for interventions and support systems that can help students manage high caseloads, stressors, and performance pressures, while also fostering and maintaining empathy. Implementing strategies such as stress management programs, mindfulness training, and self-care initiatives can help mitigate the negative impact on empathy levels and promote the development of empathetic skills in future occupational therapists. The research study's results have implications for the professional practice of occupational therapy. It emphasizes the need for ongoing education and training programs that focus on empathy development and maintenance throughout a therapist's career. By providing therapists with the tools, resources, and support to sustain their empathy levels in challenging work environments, the study suggests that the quality of care provided to clients can be enhanced, leading to better therapeutic outcomes and overall client satisfaction. Organizational changes within healthcare settings may be necessary to address workload issues and create a supportive environment that nurtures empathy among occupational therapy professionals

Vergleichen und Erzählen. Zur Verflechtung zweier Kulturtechniken

Kramer K, Carrier M, Heyder JC, Hochkirchen B. Vergleichen und Erzählen. Zur Verflechtung zweier Kulturtechniken. Praktiken des Vergleichens. Working Paper des SFB 1288. Vol 4 aktual. und erg. Version. Bielefeld: Universität Bielefeld, SFB 1288; 2020.Das Working Paper nimmt den Zusammenhang von Vergleichen und Erzählen aus einer systematischen und historischen Perspektive in den Blick. Es befasst sich zum einen mit der Frage, wie und vor dem Hintergrund welcher theoretischer Annahmen Konvergenzen, Verflechtungen und Wechselbeziehungen zwischen Vergleichspraktiken und Erzählformen postuliert werden können. Beide Praktiken – so die zentrale These – lassen sich als Kulturtechniken begreifen, die zur Formierung übergreifender Netzwerke in Beziehung gesetzt werden können, welche nicht allein durch sprachoder bildgebundene Repräsentationsprozesse gekennzeichnet sind, sondern diese in umfassendere Dynamiken zeichenhafter Darstellungsformen, sozialer Akteure und materieller Artefakte einbinden. Die systematische Perspektive schließt auch die Frage nach der Verknüpfung von Kulturtechnikforschung und Praxistheorie mit ein. Zum anderen skizziert das Papier vier exemplarische historische Konstellationen, die die moderne Wissenschaftsgeschichte, die europäische Weltreiseliteratur, Vergleiche in Bild-Text-Objekt-Hybriden sowie kuratorische Praktiken in Ausstellungen betreffen, in denen Vergleichs- und Erzählpraktiken je spezifische Wechselwirkungen eingehen und in komplexe Operationsketten mit unterschiedlichen Akteuren eingebunden sind.The working paper focuses on the connection between practices of comparing and narrating from a systematic and historical perspective. On the one hand, it tackles the question of how, and against which backdrop of theoretical assumptions, we can postulate convergences, entanglements, and interrelations between practices of comparing and narrating. The main hypothesis is that both practices can be understood as cultural techniques. They form extensive relational networks, which are not only characterized by language and image related representational processes, but first and foremost by complex dynamics linking symbolic representation, social actors, and material artefacts. The systematic perspective also comprises the question of how the approaches of cultural techniques analysis and practice theory can be related to each other. On the other hand, both the interrelation between practices of comparing and narrating as well as the complex operational chains will be outlined on the basis of four historical case studies. Those studies involve subjects such as modern history of science, European travel literature, comparisons in image-text-object hybrids as well as curatorial practices in exhibitions.**Ergänzender Hinweis zu den Creative Commons Lizenzen**"Creative Commons license terms for re-use do not apply to any content (such as graphs, figures, photos, excerpts, etc.) not original to the Open Access publication and further permission may be required from the rights holder.

The dimensionality of stability depends on disturbance type

International audienceEcosystems respond in various ways to disturbances. Quantifying ecological stability therefore requires inspecting multiple stability properties, such as resistance, recovery, persistence and invariability. Correlations among these properties can reduce the dimensionality of stability, simplifying the study of environmental effects on ecosystems. A key question is how the kind of disturbance affects these correlations. We here investigated the effect of three disturbance types (random, species-specific, local) applied at four intensity levels, on the dimensionality of stability at the population and community level. We used previously parameterized models that represent five natural communities, varying in species richness and the number of trophic levels. We found that disturbance type but not intensity affected the dimensionality of stability and only at the population level. The dimensionality of stability also varied greatly among species and communities. Therefore, studying stability cannot be simplified to using a single metric and multi-dimensionalassessments are still to be recommended
