Traktaty pedagogiczne Honoraty z Wiśniowskich Zapovej i Klementyny z Tańskich Hoffmanowej – inspiracja czy przeróbka?

As is well know, the long-lasting influence in Poland of Hoffmanowa’s conservative pedagogical treatise « Keepsake of a Good Mother » (1819) was criticized by more progressive Polish women writers of the 19th century, such as Narcyza Żmichowska and Eliza Orzeszkowa. But the unexpected success of that book in other Slav countries later in the 19th century, especially in Bohemia, is less well known. Honorata z Wiśniowskich Zapová (1825-1856), a member of the Galician Polish szlachta who moved to Prague after her marriage in 1841 to the Czech writer K. V. Zap, has been recently exhumed as a Czech writer by Czech and Polish literary criticism: apart from her essays in Czech journals on her native country, much emphasis has been laid on the value of her most important work, Nezabudky, dar našim pannám (Forget-me-not: A Gift to Our Young Ladies, published in 1859), which was the first book of pedagogy dedicated to the instruction of young women in Bohemia. In her preface to this book, Zapová mentions Hoffmanowa as being one of her many sources of inspiration. Wishing to know more about what exactly Zapová owes to Hoffmanowa, in this article I compare Hoffmanowa’s book of pedagogy with Zapová’s. I am astonished to discover that Zapová’s book is in fact an almost literal translation from Polish to Czech of „Keepsake of a Good Mother” – in other words, that it is a plagiarism of Hoffmanowa’s book. The main question I ask here is : why did no one until now, either in 19th-century criticism or in our contemporary criticism, mention this literary fraud before?

A lung-on-chip array with an integrated bio-inspired respiration mechanism

We report about a lung-on-chip array that mimics the pulmonary parenchymal environment, including the thin, alveolar barrier and the three-dimensional cyclic strain induced by the breathing movements. A micro-diaphragm used to stretch the alveolar barrier is inspired by the in-vivo diaphragm, the main muscle responsible for inspiration. The design of this device aims not only at best reproducing the in-vivo conditions found in the lung parenchyma, but also at making its handling easy and robust. An innovative concept, based on the reversible bonding of the device, is presented that enables to accurately control the concentration of cells cultured on the membrane by easily accessing both sides of the membranes. The functionality of the alveolar barrier could be restored by co-culturing epithelial and endothelial cells that formed tight monolayers on each side of a thin, porous and stretchable membrane. We showed that cyclic stretch significantly affects the permeability properties of epithelial cell layers. Furthermore, we could also demonstrate that the strain influences the metabolic activity and the cytokine secretion of primary human pulmonary alveolar epithelial cells obtained from patients. These results demonstrate the potential of this device and confirm the importance of the mechanical strain induced by the breathing in pulmonary research.

Novel radiotherapy techniques for involved-field and involved-node treatment of mediastinal Hodgkin lymphoma: when should they be considered and which questions remain open?

PURPOSE Hodgkin lymphoma (HL) is a highly curable disease. Reducing late complications and second malignancies has become increasingly important. Radiotherapy target paradigms are currently changing and radiotherapy techniques are evolving rapidly. DESIGN This overview reports to what extent target volume reduction in involved-node (IN) and advanced radiotherapy techniques, such as intensity-modulated radiotherapy (IMRT) and proton therapy-compared with involved-field (IF) and 3D radiotherapy (3D-RT)- can reduce high doses to organs at risk (OAR) and examines the issues that still remain open. RESULTS Although no comparison of all available techniques on identical patient datasets exists, clear patterns emerge. Advanced dose-calculation algorithms (e.g., convolution-superposition/Monte Carlo) should be used in mediastinal HL. INRT consistently reduces treated volumes when compared with IFRT with the exact amount depending on the INRT definition. The number of patients that might significantly benefit from highly conformal techniques such as IMRT over 3D-RT regarding high-dose exposure to organs at risk (OAR) is smaller with INRT. The impact of larger volumes treated with low doses in advanced techniques is unclear. The type of IMRT used (static/rotational) is of minor importance. All advanced photon techniques result in similar potential benefits and disadvantages, therefore only the degree-of-modulation should be chosen based on individual treatment goals. Treatment in deep inspiration breath hold is being evaluated. Protons theoretically provide both excellent high-dose conformality and reduced integral dose. CONCLUSION Further reduction of treated volumes most effectively reduces OAR dose, most likely without disadvantages if the excellent control rates achieved currently are maintained. For both IFRT and INRT, the benefits of advanced radiotherapy techniques depend on the individual patient/target geometry. Their use should therefore be decided case by case with comparative treatment planning.

Heart-lung interactions during neurally adjusted ventilatory assist

Introduction Assist in unison to the patient’s inspiratory neural effort and feedback-controlled limitation of lung distension with neurally adjusted ventilatory assist (NAVA) may reduce the negative effects of mechanical ventilation on right ventricular function. Methods Heart–lung interaction was evaluated in 10 intubated patients with impaired cardiac function using esophageal balloons, pulmonary artery catheters and echocardiography. Adequate NAVA level identified by a titration procedure to breathing pattern (NAVAal), 50% NAVAal, and 200% NAVAal and adequate pressure support (PSVal, defined clinically), 50% PSVal, and 150% PSVal were implemented at constant positive end-expiratory pressure for 20 minutes each. Results NAVAal was 3.1 ± 1.1cmH2O/μV and PSVal was 17 ± 2 cmH20. For all NAVA levels negative esophageal pressure deflections were observed during inspiration whereas this pattern was reversed during PSVal and PSVhigh. As compared to expiration, inspiratory right ventricular outflow tract velocity time integral (surrogating stroke volume) was 103 ± 4%, 109 ± 5%, and 100 ± 4% for NAVAlow, NAVAal, and NAVAhigh and 101 ± 3%, 89 ± 6%, and 83 ± 9% for PSVlow, PSVal, and PSVhigh, respectively (p < 0.001 level-mode interaction, ANOVA). Right ventricular systolic isovolumetric pressure increased from 11.0 ± 4.6 mmHg at PSVlow to 14.0 ± 4.6 mmHg at PSVhigh but remained unchanged (11.5 ± 4.7 mmHg (NAVAlow) and 10.8 ± 4.2 mmHg (NAVAhigh), level-mode interaction p = 0.005). Both indicate progressive right ventricular outflow impedance with increasing pressure support ventilation (PSV), but no change with increasing NAVA level. Conclusions Right ventricular performance is less impaired during NAVA compared to PSV as used in this study. Proposed mechanisms are preservation of cyclic intrathoracic pressure changes characteristic of spontaneous breathing and limitation of right-ventricular outflow impedance during inspiration, regardless of the NAVA level.

Determination of respiratory gas flow by electrical impedance tomography in an animal model of mechanical ventilation

Background A recent method determines regional gas flow of the lung by electrical impedance tomography (EIT). The aim of this study is to show the applicability of this method in a porcine model of mechanical ventilation in healthy and diseased lungs. Our primary hypothesis is that global gas flow measured by EIT can be correlated with spirometry. Our secondary hypothesis is that regional analysis of respiratory gas flow delivers physiologically meaningful results. Methods In two sets of experiments n = 7 healthy pigs and n = 6 pigs before and after induction of lavage lung injury were investigated. EIT of the lung and spirometry were registered synchronously during ongoing mechanical ventilation. In-vivo aeration of the lung was analysed in four regions-of-interest (ROI) by EIT: 1) global, 2) ventral (non-dependent), 3) middle and 4) dorsal (dependent) ROI. Respiratory gas flow was calculated by the first derivative of the regional aeration curve. Four phases of the respiratory cycle were discriminated. They delivered peak and late inspiratory and expiratory gas flow (PIF, LIF, PEF, LEF) characterizing early or late inspiration or expiration. Results Linear regression analysis of EIT and spirometry in healthy pigs revealed a very good correlation measuring peak flow and a good correlation detecting late flow. PIFEIT = 0.702 · PIFspiro + 117.4, r2 = 0.809; PEFEIT = 0.690 · PEFspiro-124.2, r2 = 0.760; LIFEIT = 0.909 · LIFspiro + 27.32, r2 = 0.572 and LEFEIT = 0.858 · LEFspiro-10.94, r2 = 0.647. EIT derived absolute gas flow was generally smaller than data from spirometry. Regional gas flow was distributed heterogeneously during different phases of the respiratory cycle. But, the regional distribution of gas flow stayed stable during different ventilator settings. Moderate lung injury changed the regional pattern of gas flow. Conclusions We conclude that the presented method is able to determine global respiratory gas flow of the lung in different phases of the respiratory cycle. Additionally, it delivers meaningful insight into regional pulmonary characteristics, i.e. the regional ability of the lung to take up and to release air.

Finding a voice - Nollywood inspired filmmaking practices in Switzerland

Under the name Nollywood a unique video film industry has developed in Nigeria in the last few decades, which now forms one of the world’s biggest entertainment industries. With its focus on stories reflecting „the values, desires and fears” (Haynes 2007: 133) of African viewers and its particular way of production, Nollywood brings „lived practices and its representation together in ways that make the films deeply accessible and entirely familiar to their audience“ (Marston et al. 2007: 57). In doing so, Nollywood shows its spectators new postcolonial forms of performative self‐expression and becomes a point of reference for a wide range of people. However, Nollywood not only excites a large number of viewers inside and outside Nigeria, it also inspires some of them to become active themselves and make their own films. This effect of Nigerian filmmaking can be found in many parts of sub‐Saharan Africa as well as in African diasporas all over the world – including Switzerland (Mooser 2011: 63‐66). As a source of inspiration, Nollywood and its unconventional ways of filmmaking offer African migrants a benchmark that meets their wish to express themselves as minority group in a foreign country. As Appadurai (1996: 53), Ginsburg (2003: 78) and Marks (2000: 21) assume, filmmakers with a migratory background have a specific need to express themselves through media. As minority group members in their country of residence they not only wish to reflect upon their situation within the diaspora and illustrate their everyday struggles as foreigners, but to also express their own views and ideas in order to challenge dominant public opinion (Ginsburg 2003: 78). They attempt to “talk back to the structures of power” (2003: 78) they live in. In this process, their audio-visual works become a means of response and “an answering echo to a previous presentation or representation” (Mitchell 1994: 421). The American art historian Mitchell, therefore, suggests interpreting representation as “the relay mechanism in exchange of power, value, and publicity” (1994: 420). This desire of interacting with the local public has also been expressed during a film project of African, mainly Nigerian, first-generation migrants in Switzerland I am currently partnering in. Several cast and crew members have expressed feelings of being under-represented, even misrepresented, in the dominant Swiss media discourse. In order to create a form of exchange and give themselves a voice, they consequently produce a Nollywood inspired film and wish to present it to the society they live in. My partnership in this on‐going film production (which forms the foundation of my PhD field study) allows me to observe and experience this process. By employing qualitative media anthropological methods and in particular Performance Ethnography, I seek to find out more about the ways African migrants represent themselves as a community through audio‐visual media and the effect the transnational use of Nollywood has on their form of self‐representations as well as the ways they express themselves.

Die Gletscher des Welterbes Jungfrau-Aletsch im Spiegel der Zeit

Die Gletscher der Region Jungfrau-Aletsch und deren einzigartige Schönheit waren während Jahrhunderten nicht nur Inspiration für Besucher und Einheimische, sondern auch entscheidende Kriterien für die Auszeichnung des Gebietes mit dem UNESCO-Welterbe-Label. Mit 167 kleinen und grossen Gletschern liegt die Region zu 42% unter Eis und umfasst die grösste zusammenhängende Eisfläche der Alpen. Im Zuge der Klimaerwärmung ziehen sich die Gletscher jedoch kontinuierlich zurück und stellen die Menschen im Alpenraum vor vielfältige Herausforderungen. Wie präsentiert sich die Situation im Welterbe-Gebiet?

Entre las múltiples cualidades humanas e intelectuales de Gregorio Weinberg, se pone de relieve la faz educativa: como docente, director de colecciones y editor. Se destaca especialmente la fecunda integración que logró entre modernización e identidad en sus proyectos editoriales y educativos, de los que resulta una suerte de vindicación hispanoamericana de inspiración martiana.

Oriente y mundo clásico en José Vasconcelos

En muchos aspectos el pensamiento de José Vasconcelos (1882–1959) sufrió cambios notables durante su vida. Sus ideas sobre el mundo clásico grecorromano y el Oriente también los experimentaron. A diferencia de sus contemporáneos reunidos en el Ateneo de la Juventud, fue crítico del mundo clásico y buscó fuentes de inspiración estética y moral en la India, mostró curiosidad por el Japón y por el Islam. Sus ideas sobre el mestizaje y la "raza cósmica" deben mucho a este interés. Con los años, sin embargo, su creciente conservatismo también influyó en sus ideas sobre el mundo clásico y el Oriente. Este último le fue cada vez más alejado, sobre todo el Islam, objeto de su odio principal. Como ello se daba cuando otros intelectuales enrolados en la izquierda ensayaban un movimiento de simpatía hacia el mundo colonial, contribuyeron a exacerbar la reacción de Vasconcelos.

Filosofía, mito y nación en el Prometeo de Leopoldo Lugones

Si bien el pensamiento de Leopoldo Lugones ha sido interpretado como autoritario y monológico, esta mirada puede ser puesta en cuestión desde la imbricación entre nacionalismo y universalismo que atraviesa sus obras de inspiración modernista. Su libro Prometeo (un proscripto del sol) –obra de pedagogía estética y homenaje al Centenario de la Patria– liga una "estética de la nacionalidad" con la defensa de los valores de la Ilustración. Sobre todo con el valor de la libertad y, desde el plano del poeta, de la libertad creadora. Este trabajo pretende interpretar, desde una hermenéutica en la cual dialoga la filosofía con el pensamiento mítico, los posibles usos del mito en la escritura lugoniana del Prometeo. Usos que pueden dar lugar tanto al núcleo constitutivo de lo que será su discurso nacionalista más excluyente a partir las conferencias de 1913 sobre el poema Martín Fierro, como a una defensa de la autonomía poética ante el mundo burgués vinculada a cierta forma de pensamiento utópico.

Alberto Magno y la revisión de la teoría hilemórfica de Aristóteles

La doctrina hilemórfica de la materia como pura potencia y la forma como acto parece no satisfacer al dominico Alberto Magno, pues le resulta insuficiente para explicar los procesos naturales. Por esto, redefine los principios metafísicos fundamentales del aristotelismo, y asimismo expone nuevos principios constitutivos de la realidad, bajo inspiración de la filosofía neoplatónica y del pensamiento árabe. Así, Alberto sostiene que la materia prima debe ser entendida como una suerte de realidad actualizada, compuesta por diversas formas incoadas previamente al advenimiento de la forma sustancial. La incohatio formae, según el dominico, dispone a la materia a recibir cierta forma en vez de otra en la futura generación, lo cual justifica la regularidad de todo proceso natural. La materia primera, entonces, no participa meramente como sustrato del cambio sustancial y no puede ser definida como una realidad completamente simple. Por sí misma, posee un esse materiae y constituye una entidad substancial, la materia posee un ser independiente de la forma, al igual que la forma es independiente de la materia. En los tratados de la Physica y Metaphysica, Alberto Magno desarrolla una doctrina propia, aunque claramente influenciada por la cosmología y metafísica averroísta.
