The Voyage of Impressionism in Three Violin Recitals: To See the World in Different Colors

Impressionism serves as the transition between romantic and modern music. This dissertation examines the varying characteristics and colors of Impressionism in the works of late-romantic French composers, French Impressionistic composers, and composers with Impressionistic influence from countries other than France. Violin Sonata in g minor, L. 140 (1917) is the last work composed by Claude Debussy. The impressionistic characters in this work includes the ambiguous yet innovative and variant sonority and form. As a work also written in 1917, Ottorino Respighi's Violin Sonata in b minor is deeply rooted in Italian Romanticism. Some of the Impressionistic characters can be found in the second movement where the harmonies are in parallel motion. César Franck, a forerunner of impressionism, heavily influenced Debussy with the use of cyclic form. The Violin Sonata in A major (1886) is rich in harmonic language. Ernest Chausson's works mark the transition between Franck and Debussy. The Poème portrays a love story, Song of Love Triumphant by Turgenev. The work is a symphonic poem for violin and orchestra. The Mythes, Op. 30 (1915) by Karol Szymanowski is based on Greek mythology. Ravel's Sonata for Violin and Cello (1922), dedicated to Debussy, points to the future with a sophisticated harmonic language extending into atonality, spare texture, and expanded palate of impressionistic colors and techniques. Ernest Bloch's Violin Sonata No. 1 (1920) portrays the feeling of torment. Beneath the soaring cries of the violin, the harmonic sonority of Impressionism are present. Gabriel Fauré's Violin Sonata No. 1 in A major, op. 13 (1876) is the earliest work of this project. The scherzo movement became a prototype for future scherzo movements for Ravel and Debussy. Ravel's Tzigane (1924), at once a paragon of French impressionism, a delightful gypsy-style dance-fantasy, and a breathtaking virtuoso piece, is the perfect conclusion to my dissertation project. The pieces discussed above were presented in three recitals. Compact disc recordings of these recitals are available in the Michelle Smith Performing Arts Library of the Clarice Smith Performing Arts Center at the University of Maryland.

Violence Exposure and Welfare over Time: Evidence from the Burundi Civil War

We investigate the relationship between exposure to conflict and poverty dynamics over time, using original three-waves panel data for Burundi which tracked individuals and reported local-level violence exposure from 1998 to 2012. Firstly, the data reveal that headcount poverty has not changed since 1998 while we observe multiple transitions into and out of poverty. Moreover, households exposed to the war exhibit a lower level of welfare than non-exposed households, with the difference between the two groups predicted to remain significant at least until 2017, i.e. twelve years after the conflict termination. The correlation between violence exposure and deprivation over time is confirmed in a household-level panel setting. Secondly, our empirical investigation shows how violence exposure over different time spans interacts with households' subsequent welfare. Our analysis of the determinants of households' likelihood to switch poverty status (i.e. to fall into poverty or escape poverty) combined with quantile regressions suggest that, (i) exposure during the first phase of the conflict has affected the entire distribution, and (ii) exposure during the second phase of the conflict has mostly affected the upper tail of the distribution: initially non-poor households have a higher propensity to fall into poverty while initially poor households see their propensity to pull through only slightly decrease with recent exposure to violence. Although not directly testable with the data at hand, these results are consistent with the changing nature of violence in the course of the Burundi civil war, from relatively more labour-destructive to relatively more capital-destructive.

Cambio de concepciones de un grupo de futuros profesores de matemática sobre su gestión del proceso de enseñanza-aprendizaje en un ambiente de aprendizaje fundamentado en la resolución de problemas

Ernest (1989) afirmó que las creencias y concepciones de un profesor regulan su práctica de enseñanza en el aula. De esta manera, si se desean cambios en las prácticas de los profesores de matemáticas, al parecer, deben cambiar sus creencias y concepciones. Al respecto se generó la pregunta: ¿es posible cambiar las creencias y concepciones de los profesores? (Thompson, 1991). Las investigaciones de Senger (1999), D’Amore y Fandiño (2004) y Pehkonen (2006), entre otras, han arrojado resultados positivos acerca de que las creencias y concepciones de los profesores pueden cambiar. En este artículo se presentarán los resultados de una investigación cuyo objetivo primordial fue identificar y caracterizar cambios en las concepciones de los estudiantes para profesor de sexto semestre de Licenciatura en Educación Básica con Énfasis en Matemáticas (Bogotá, Colombia). En esencia se presentarán resultados que muestran las concepciones iniciales de los estudiantes y su cambio al finalizar la intervención.

“The new Cagliostro”: Onofroff, Rubén Darío and his story "La esfinge"

The article retraces the career of the famous hypnotist Onofroff and particularly his visit to Buenos Aires, where his activity, in 1895, provoked many discussions and some public embarrassment. In this context Darío, using a pseudonym, published his crónica “La esfinge”. We reproduce “La esfinge”, transcribing the original text of La Nación, with annotations identifying the literary and theosophical sources Darío used when he wrote it.

Alegoría: su pertinencia en la predicación y uso en "La novena maravilla"

En este artículo se focaliza el recurso de la alegoría como método exegético en la composición de los sermones panegíricos de Juan Espinosa Medrano (Perú, siglo XVII). Se traza el recorrido de la alegoría (y las humanidades en general) en relación –siempre tensa– con el cristianismo a lo largo de su historia; y se llega a la Contrarreforma y el uso exacerbado del método en la predicación barroca; particularmente en la oratoria sagrada de Espinosa Medrano, quien abarca elementos diversos y extraídos de distintas fuentes (filosofía natural, mitología clásica, tradición emblemática, relatos bíblicos), a los que hace funcionar como signos de otra verdad mayor, la sagrada. Si bien las preceptivas sagradas impulsaban una predicación más llana y simple, la profusión de alegorías mitológicas, que el autor resemantiza según su interés de guiar la interpretación, pueden explicarse por varias circunstancias, motivos de estudio en este trabajo.

The notion of space in the artistic language of Alfredo Jaar

Conceptual art and communicator role has influenced the work of Chilean architect Alfredo Jaar, which has been proposed report, with other codes [verbal and nonverbal], global events influencing contemporary society. His early training as an architect has driven innovation in the design of artistic space , using the message to convey to the viewer the reason for his work for more than three decades, highlights the artistic composition with various material resources whose purpose lies in conceptualizing various topics relevant in considering the role of artistic communication. Jaar’s style is the sum of his own life experience in relation to the contradictions of the world today, which is exposed and from the perspective of postmodernism from the exploitation of the notion of space as an open stage for visual and expressiveness beyond national borders, societies and cultures of the world.

Risk assessment of potentially toxic elements in agricultural soils and maize tissues from selected districts in Tanzania

A field survey was conducted to investigate the contamination of potentially toxic elements (PTEs) arsenic (As), lead (Pb), chromium (Cr), and nickel (Ni) in Tanzanian agricultural soils and to evaluate their uptake and translocation in maize as proxy to the safety of maize used for human and animal consumption. Soils and maize tissues were sampled from 40 farms in Tanzania and analyzed using inductively coupled plasma-mass spectrometry in the United Kingdom. The results showed high levels of PTEs in both soils and maize tissues above the recommended limits. Nickel levels of up to 34.4 and 56.9mgkg(-1) respectively were found in some maize shoots and grains from several districts. Also, high Pb levels >0.2mgkg(-1) were found in some grains. The grains and shoots with high levels of Ni and Pb are unfit for human and animal consumption. Concentrations of individual elements in maize tissues and soils did not correlate and showed differences in uptake and translocation. However, Ni showed a more efficient transfer from soils to shoots than As, Pb and Cr. Transfer of Cr and Ni from shoots to grains was higher than other elements, implying that whatever amount is assimilated in maize shoots is efficiently mobilized and transferred to grains. Thus, the study recommended to the public to stop consuming and feeding their animals maize with high levels of PTEs for their safety.

Insulin receptor substrate-2 is expressed in kidney epithelium and up-regulated in diabetic nephropathy

Diabetic nephropathy (DN) is a progressive fibrotic condition that may lead to end-stage renal disease and kidney failure. Transforming growth factor-ß1 and bone morphogenetic protein-7 (BMP7) have been shown to induce DN-like changes in the kidney and protect the kidney from such changes, respectively. Recent data identified insulin action at the level of the nephron as a crucial factor in the development and progression of DN. Insulin requires a family of insulin receptor substrate (IRS) proteins for its physiological effects, and many reports have highlighted the role of insulin and IRS proteins in kidney physiology and disease. Here, we observed IRS2 expression predominantly in the developing and adult kidney epithelium in mouse and human. BMP7 treatment of human kidney proximal tubule epithelial cells (HK-2 cells) increases IRS2 transcription. In addition, BMP7 treatment of HK-2 cells induces an electrophoretic shift in IRS2 migration on SDS/PAGE, and increased association with phosphatidylinositol-3-kinase, probably due to increased tyrosine/serine phosphorylation. In a cohort of DN patients with a range of chronic kidney disease severity, IRS2 mRNA levels were elevated approximately ninefold, with the majority of IRS2 staining evident in the kidney tubules in DN patients. These data show that IRS2 is expressed in the kidney epithelium and may play a role in the downstream protective events triggered by BMP7 in the kidney. The specific up-regulation of IRS2 in the kidney tubules of DN patients also indicates a novel role for IRS2 as a marker and/or mediator of human DN progression.

A.J. Raffles and Arsène Lupin in Literature, Theatre, and Film: On The Transnational Adaptations of Popular Fiction (1905-1930)

As a consequence of the accelerating technological development and the impact of cultural globalisation, the transnational aspects of the process of adaptation have become increasingly crucial in recent years. To go back to the very beginnings of the twentieth century and research the historical connections between popular literature, theatre, and film can shed greater light on the origins of these phenomena. By focusing on two case studies from turn-of-the-century crime fiction, this paper examines the extent to which practices of serialisation, translation, and adaptation of literary works contributed to the formation of a transnational market for popular culture. Ernest W. Hornung’s A. J. Raffles and Maurice Leblanc’s Arsène Lupin were the heroes of two crime series that were immediately translated, imitated, and adapted into countless theatrical plays and films all over the world. Given the resemblance between the two characters, the two franchises frequently ended by overlapping. Their ability to move from a medium to another as well as from a country to another was the result of the logic of ‘recycling, remaking, retelling’ (Brian Naremore) that guides not only the process of adaptation but also the creation of any work of popular culture.

Affinity-Purified Respiratory Syncytial Virus Antibodies from Intravenous Immunoglobulin Exert Potent Antibody-Dependent Cellular Cytotoxicity

Mixed infections are one of the major therapeutic challenges, as the current strategies have had limited success. One of the most common and widespread conditions of mixed infection is respiratory syncytial virus-mediated pathology of the respiratory tract in children. There is a dire need for the development of novel therapeutic approaches during mixed infections. Therapeutic intravenous immunoglobulin preparations, obtained from plasma pools of healthy donors have been used in immune deficiencies. This study was thus designed to characterize the functional efficacy of RSV-specific antibodies in IVIg. To explore the functional ability of these affinity-purified RSV-specific antibodies, the antibody-dependent and complement dependent cytotoxicity was determined using peripheral cells of healthy donors. This study demonstrates the existence of highly potent RSV-specific antibodies in IVIg preparations and provides the basis for the use of IVIg as broad-spectrum protective shield to RSV-infected children during mixed infections

Integrated care pathways for airway diseases (AIRWAYS-ICPs)

The objective of Integrated Care Pathways for Airway Diseases (AIRWAYS-ICPs) is to launch a collaboration to develop multi-sectoral care pathways for chronic respiratory diseases in European countries and regions. AIRWAYS-ICPs has strategic relevance to the European Union Health Strategy and will add value to existing public health knowledge by: 1) proposing a common framework of care pathways for chronic respiratory diseases, which will facilitate comparability and trans-national initiatives; 2) informing cost-effective policy development, strengthening in particular those on smoking and environmental exposure; 3) aiding risk stratification in chronic disease patients, using a common strategy; 4) having a significant impact on the health of citizens in the short term (reduction of morbidity, improvement of education in children and of work in adults) and in the long-term (healthy ageing); 5) proposing a common simulation tool to assist physicians; and 6) ultimately reducing the healthcare burden (emergency visits, avoidable hospitalisations, disability and costs) while improving quality of life. In the longer term, the incidence of disease may be reduced by innovative prevention strategies. AIRWAYSICPs was initiated by Area 5 of the Action Plan B3 of the European Innovation Partnership on Active and Healthy Ageing. All stakeholders are involved (health and social care, patients, and policy makers).

Accessory minerals and potentially toxic elements in Tanzanian vermiculites with respect to agricultural applications

The study assessed accessory minerals and metals in Tanzanian vermiculites with respect to their potential suitability for agricultural applications. Mineral and chemical analyses were involved. Pot experiments were also conducted to assess plant uptake of metals from soil with vermiculites. Fibrous sepiolite and amphiboles were minerals of health concern found in some samples. The sepiolite fibers had aspect ratios similar to those of asbestos minerals, which cause respiratory disorders and lung cancer when inhaled and thus pose a potential health risk to animals and humans. The amphibole fibers were thicker than 10 μm and are unlikely to be inhaled. Chromium (Cr) and nickel (Ni) concentrations in some samples were greater than the limits permitted in agricultural soils, but the elements are not highly plant available and do not inhibit the uptake of essential macronutrients. Heating vermiculites at 400-600° C enhanced extractability of Cr and Ni and should preferably be avoided. © Taylor & Francis Group, LLC.
