Cavitation induced by shock wave focusing in eye-like experimental configurations
Authors: Požar Tomaž , Petkovšek Rok
Published: December 2019

During laser-induced, breakdown-based medical procedures in human eyes such as posterior capsulotomy and vitreolysis, shock waves are emitted from the location of the plasma. A part of these spherically expanding transients is reflected from the concave surface of the corneal epithelium and refocused within the eye. Using a simplified experimental model of the eye, the dominant secondary cavitation clusters were detected by high-speed camera shadowgraphy in the refocusing volume, dislocated from the breakdown position and described by an abridged ray theory. Individual microbubbles were detected in the preheated cone of the incoming laser pulse and radially extending cavitation filaments were generated around the location of the breakdown soon after collapse of the initial bubble. The generation of the secondary cavitation structures due to shock wave focusing can be considered an adverse effect, important in ophthalmology.

Published: December 2019

The paper presents the results of experimental studies of the effect of selective photo-excitation on the diffusion of molecules of organic dyes Rhodamine 6G and Oxazine 1 perchlorate through silica gel. The experimental results are compared with the theoretical model presented in our previous work, which describes a decrease in the diffusion rate of molecules being excited by laser radiation and brought into triplet state. The experimental data obtained in the course of the present study are in qualitative agreement with the model just mentioned. It was shown that after selective photo-excitation of Rhodamine 6G molecules and their transition into triplet state, the diffusion rate decreased by 40% compared with molecules in the ground state.
Open loop control theory algorithms for high-speed 3D MEMS optical switches
Authors: Pollock C. , Pardo F. , Imboden M. , Bishop D. J.
Published: December 2019

There is a world-wide push to create the next-generation all-optical transmission and switching technologies for exascale data centers. In this paper we focus on the switching fabrics. Many different types of 2D architectures are being explored including MEMS/waveguides and semiconductor optical amplifiers. However, these tend to suffer from high, path-dependent losses and crosstalk issues. The technologies with the best optical properties demonstrated to date in large fabrics (>100 ports) are 3D MEMS beam steering approaches. These have low average insertion losses and, equally important, a narrow loss distribution. However, 3D MEMS fabrics are generally dismissed from serious consideration for this application because of their slow switching speeds (∼few milliseconds) and high costs ($100/port). In this paper we show how novel feedforward open loop controls can solve both problems by improving MEMS switching speeds by two orders of magnitude and costs by a factor of three. With these improvements in hand, we believe 3D MEMS fabrics can become the technology of choice for data centers.
Intensity modulation based optical proximity optimization for the maskless lithography
Authors: Liu Jianghui , Liu Junbo , Deng Qingyuan , Feng Jinhua , Zhou Shaolin , Hu Song
Published: December 2019

The undesirable optical proximity effect (OPE) that appeared in the digital micro-mirrors device (DMD) based maskless lithography directly influences the final exposure pattern and decreases the lithography quality. In this manuscript, a convenient method of intensity modulation applied for the maskless lithography is proposed to optimize such an effect. According to the pulse width modulation based image recognition of DMD, we replaced the digital binary mask with a special digital grayscale mask to modulate the UV intensity distribution to be closer to the expectation in a way of point-by-point modification. The exposure result applying the grayscale mask has a better consistency with the design pattern than that for the case in which the original binary mask is used. The effectiveness of this method was analyzed by the image subtraction technique. Experimental data revealed that the matching rate between the exposure pattern and the mask pattern has been improved from 78% to 91%. Besides, more experiments have been conducted to verify the validity of this method for the optical proximity optimization and its potential in the high-fidelity DMD based maskless lithography.
Tracking the polarisation state of light via Hong-Ou-Mandel interferometry
Authors: Harnchaiwat Natapon , Zhu Feng , Westerberg Niclas , Gauger Erik , Leach Jonathan
Published: December 2019

We provide a statistically robust and accurate framework to measure and track the polarisation state of light employing Hong-Ou-Mandel interference. This is achieved by combining the concepts of maximum likelihood estimation and Fisher information applied to photon detection events. Such an approach ensures that the Cramér-Rao bound is saturated and changes to the polarisation state are established in an optimal manner. Using this method, we show that changes in the linear polarisation state can be measured with 0.6 arcminute precision (0.01 degrees).
Discretized superimposed optical fiber long-period gratings
Authors: Trono Cosimo , Valeri Federico , Baldini Francesco
Published: December 2019

A novel technique, to the best of our knowledge, for the inscription of superimposed long-period gratings with arbitrary grating pitches is proposed and experimentally validated. The technique is based on the discretization of an ideal continuous sinusoidal refractive index (RI) pattern with a step function. The RI variation is induced by means of the irradiation of a photosensitive fiber with a 248 nm UV laser beam. The nonlinear relation between the induced RI change and the UV fluence was experimentally derived. Two superimposed long-period grating (LPGs) with different grating pitches have been realized with the discretization technique; the transmission spectrum was compared with that of two superimposed LPGs obtained with the traditional square wave RI modulation. The validity of the proposed technique was demonstrated by the better spectral characteristics of the discretized superimposed LPGs.

Published: December 2019

Recent advancements in whole slide imaging (WSI) have moved pathology closer to digital practice. Existing systems require precise mechanical control, and the cost is prohibitive for most individual pathologists. Here we report a low-cost and high-throughput WSI system termed OpenWSI. The reported system is built using off-the-shelf components, including a programmable LED array, a photographic lens, and a low-cost computer numerical control (CNC) router. Different from conventional WSI platforms, our system performs real-time single-frame autofocusing using color-multiplexed illumination. For axial positioning control, we perform coarse adjustment using the CNC router and precise adjustment using the ultrasonic motor ring in the photographic lens. By using a 20X objective lens, we show that the OpenWSI system has a resolution of

High-dimensional quantum gates using full-field spatial modes of photons
Authors: Brandt Florian , Hiekkamäki Markus , Bouchard Frédéric , Huber Marcus , Fickler Robert
Published: December 2019

Unitary transformations are the fundamental building blocks of gates and operations in quantum information processing, allowing the complete manipulation of quantum systems in a coherent manner. In the case of photons, optical elements that can perform unitary transformations are readily available only for some degrees of freedom, e.g., wave plates for polarization. However, for high-dimensional states encoded in the transverse spatial modes of light, performing arbitrary unitary transformations remains a challenging task for both theoretical proposals and actual implementations. Following the idea of multi-plane light conversion, we show that it is possible to perform a broad variety of unitary operations at high quality by using only a few phase modulation planes. More importantly, we experimentally implement several high-dimensional quantum gates for up to five-dimensional states encoded in the full-field mode structure of photons. In particular, we realize cyclic and quantum Fourier transformations, known as Pauli

-gates and Hadamard

-gates, respectively, with an average visibility of more than 90%. In addition, we demonstrate near-perfect “unitarity” by means of quantum process tomography, unveiling a process purity of 99%. Last, we demonstrate the benefit of the two independent spatial degrees of freedom, i.e., azimuthal and radial, and implement a two-qubit controlled-NOT quantum operation on a single photon. Thus, our demonstrations open up new paths to implement high-dimensional quantum operations, which can be applied to various tasks in quantum communication, computation, and sensing schemes.
Is an anarchist business organization possible? Textile firms in the industrial district of Alcoi during the Spanish Civil War (1936-39)
Authors: Cuevas Casaña Joaquim , Gálvez Muñoz Lina , Torró Gil Lluís
Published: December 2019

During the Spanish Civil War, in the Republican side, a social revolution broke out, led by the workers and their unions ending in many places in a business collectivization process. In the city of Alcoi, the anarchist union took control over more than 100 textile family firms, going through a rationalization process which unified the production of all textile firms overcoming a previous production crisis and attending the war demand. Does the Alcoi case during the Civil War prove the possibility of a successful anarchist business organization? This article tries to understand the development of business without a capitalist organization and the role of business networks in such a development. The organizational design and the administration of the collectivization process is an example of how socialization of the property and democratization of the decision-making process in the company were not opposed with rationality and efficiency, at least during a war context.
Orígenes del movimiento proteccionista: algunos conceptos y fundamentos
Authors: Marchena Domínguez José
Published: December 2019

Desde 1824 con la creación de la Royal Society for the Prevention of Cruelty to Animals (RSPCA) en Londres, las protectoras destinaron su tiempo a desarrollar acciones en defensa de un mundo más respetuoso con el medio ambiente, y ello desde varios niveles: la lucha desde el marco legal que permitiera una normativa cada vez más consecuente con el mundo animal y vegetal; las movilizaciones desde grandes ciudades hasta pequeñas poblaciones para evitar acciones inhumanas desde la cotidianeidad, el modelo socioeconómico y el ocio; y el desarrollo de un corpus teórico y una vanguardia propagandista, pedagógica y formativa. Muchos de los fundamentos ideológicos que dieron base a estos proteccionistas decimonónicos –anotamos al británico Salt entre otros‒, provinieron de la evolución teórica acerca de las actitudes morales para con los animales y la naturaleza –Grecia, sociedades cristianas y orientales, renacimiento, racionalismo, utilitarismo y contractualismo principalmente‒. Reflejamos desde la perspectiva cultural proteccionista cómo se produjo este tránsito desde los primeros conceptos, hasta la consolidación de una teoría sensible con el medioambiente en el escenario de las sociedades modernas e industriales de Europa y América.
La evolución estética de la naturaleza en la obra poética de José de Siles
Authors: Ocampos Palomar Emilio José
Published: December 2019

José de Siles (1856-1911) fue un autor que sufrió la bohemia y su lírica formó parte de un primer Modernismo español. Este trabajo pretende acercarse a su poesía y analizar cómo se ve alterado el tema de la naturaleza en la misma a través de una evolución estética que recorre el gusto clásico, romántico y moderno. Así, veremos cómo Siles recurre al locus amoenus para describirnos su aldea, Puente Genil, e idealizar la naturaleza siguiendo el modelo poético renacentista; cómo el paisaje natural refleja estados de la subjetividad del poeta, remitiéndonos a la Naturphilosophie y a la poesía romántica; y, finalmente, cómo abandona toda idealización clásica y evasión romántica de la naturaleza para hablar de su impureza y dejarla al margen, ya que el espacio que interesará a la poesía moderna será el de la ciudad.
La quinta columna y el cuerpo diplomático en la Guerra Civil española
Authors: Nuñez de Prado Clavell Sara , Rodriguez Abengozar Javier
Published: December 2019

El presente trabajo aborda uno de los aspectos menos estudiados de la Guerra Civil española, como es la relación entre la quinta columna y el cuerpo diplomático. Sobre la base del estudio de la documentación original custodiada en distintos archivos, se pone de manifiesto cómo en muchas ocasiones esa relación traspasó los límites propios de la actividad diplomática y su labor humanitaria, convirtiendo a distintos diplomáticos en colaboradores, no siempre de manera consciente, de la causa franquista. Asimismo, se hace referencia a cómo tales actuaciones dificultaron las relaciones del Gobierno de la República con las distintas representaciones internacionales.

Published: December 2019

The genus Cotoneaster consists of unarmed shrubs that naturally distributed in north parts of Iran. It is a problematic genus, and there are many discussions about its species number in Iran as well the World. Recently, M Khatamsaz has been listed 19 species of it in Iran. In the current research, we studied leaf flavonoid composition of seven Cotoneaster species from Iran. These species were harvested from the northern provinces of the country and their leaf ethanolic extracts were subjected to HPLC, for detection the types and amounts of their flavonoid compounds. We identified four flavonoid compounds: rutin, myricetin, quercetin, and kaempferol. The concentration of these flavonoids differed between the species, moreover amount of each flavonoid also varied among the studied species. All of them were registered in the studied species, except for myricetin, which was not observed in C. nummularius. The highest amount of flavonoids were detected in C. nummularius, while C. discolor had the lowest one. The evaluated species divided into four distinct group in UPGMA tree. According to CA-Joined plot, each group was characterized by species amount of flavonoid(s). All of evaluated species belonged to the same section of the genus, therefore our findings revealed that the flavonoid data were useful at sectional level for identification of the species.
Invasive and potentially invasive plant species in State Nature Biosphere Reserves of the Altai Republic (Russia)
Authors: Artemov I.A. , Zykova E. Yu.
Published: December 2019

In the Altaiskiy and Katunskiy State Nature Biosphere Reserves we registered 44 alien plant species, which were considered in Siberia as invasive and potentially invasive. Among them, there were 30 xenophytes and 14 ergasiophytes species. Rumex acetosella L., Impatiens glandulifera Royle, Galinsoga ciliata (Rafin.) Blake, and Strophiostoma sparsiflorum (Mikan ex Pohl) Turcz. are considered invasive in the Altaiskiy Reserve because they actively spread there in natural and seminatural plant communities and habitats. Most of the species had appeared in the territories of the reserves before their establishment as a result of agricultural activity or appeared after their establishment because of activity of the reserves themselves. Despite of a big amount of tourists in the reserves, the invasive and potentially invasive plants are absent on the ecological paths at present.

A saúde brasileira não se diferencia de muitas áreas de interesse público no Brasil, onde a realidade vivenciada pela população está muito distante da ampla cobertura registrada na lei. Este trabalho tem por objetivo avaliar a magnitude das despesas da sociedade brasileira na área da saúde, abrangendo tanto os gastos públicos como os gastos privados das famílias, a partir de uma comparação de dados agregadosde países de renda média da América Latina e dos Brics. Os resultados indicam que os gastos na área da saúde no Brasil estão acima da média da amostra selecionada, com os gastos públicos ocupando uma posição intermediária, compatível com nosso nível de renda. Diante das restrições impostas pela condição econômica, é preciso intensificar o debate voltado à racionalização e priorização desses gastos.
Celso Furtado subestimou a industrialização antes de 1930? Uma sistematização das críticas à interpretação estruturalista
Authors: Ecos Gonzales Nathalia Nascimento , Salomão Ivan Colangelo
Published: December 2019

A controvérsia historiográfica que se estabeleceu entre as interpretações de Celso Furtado e Carlos Peláez acerca das origens da industrialização brasileira foi posteriormente qualificada por diversos autores. Ainda que alguns dos analistas arrolados neste artigo tenham chancelado parte da tese de Furtado, todos concordam com a existência de um relevante setor industrial anterior à eclosão da crise dos anos 1930. Assim, este trabalho tem por objetivo sistematizar as principais críticas à análise estruturalista de Furtado a esse respeito, apresentada a partir do capítulo 30 de Formação Econômica do Brasil.
A inserção do Brasil no mercado mundial de bens ambientais: uma comparação entre as listas da OCDE e da APEC
Authors: Ansanelli Stela Luiza de Mattos , Cintrão Matheus Gongalves
Published: December 2019

O objetivo deste trabalho é investigar a inserção comercial do Brasil no mercado mundial de bens ambientais comparando as listas da Organização para a cooperação e Desenvolvimento Econômico (OCDE) e da Cooperação Econômica Ásia-Pacífico (APEC) de 2001 a 2016, por meio do cálculo do Índice de VantagensComparativas Reveladas (IVCR), classificação de intensidade tecnológica e Cálculo do Índice de Comércio Intraindústria (CII). Como resultados, observou-se que o Brasil desfrutou de maiores vantagens relativas, com destaque para o etanol, e obteve o maior número de produtos com elevada intensidade tecnológica, mais pela lista da OCDE do que da APEC. Notou-se também que o Brasil realizou comércio interindustrial para todos os produtos com maiores IVCRs pela lista da OCDE. Tais resultados ressaltam os benefícios comerciais do etanol e apontam que uma liberalização via lista OCDE pode tornar o país especializado na exportação de bens com maiores IVCRs e na importação de bens com baixas vantagens, favorecendo a entrada de novas tecnologias ambientais.
Uma avaliação econométrica da trajetória do pass-through da taxa de câmbio e das pressões de demanda e oferta sobre a inflação no período 1999-2017
Authors: Santolin Roberto , Carvalho Fabrícia
Published: December 2019

O trabalho analisa o desempenho econométrico de estimativas utilizadas na avaliação do pass-through cambial, além dos choques de demanda e oferta sobre a inflação. A metodologia empregada avaliou em que medida os coeficientes estimados, e cada respectivo p-valor, apresentaram mudanças entre 1999 a 2017. Os resultados apontaram para uma mudança na trajetória dos coeficientes estimados, tal que o pass-through cambial reduziu seu impacto sobre o IPA e o IPCA a partir de 2009. Tais resultados foram corroborados por análises impulso-resposta e sugerem que, após 2009, o IPCA e o IPA tornaram-se suscetíveis às variações do hiato do produto e das commodities.

Creencias de futuros docentes sobre la gramática en la enseñanza de idiomas
Authors: Estrada Chichón José Luis , Zayas Martínez Francisco
Published: December 2019

En este artículo se examinan las creencias de alumnos del grado en Educación Infantil en una universidad pública española de tamaño medio (20 000 estudiantes, aprox.) respecto del concepto de gramática en la enseñanza de idiomas. El trabajo se articula a partir de sus experiencias preuniversitarias, confrontándolas con su formación idiomática actual en la asignatura “Didáctica de la lengua extranjera en Educación Infantil: inglés”. La metodología de investigación implica un enfoque mixto por combinar datos cuantitativos y cualitativos, a saber: i) utilizamos un cuestionario (Cook y Singleton, 2014) con el objeto de recopilar las opiniones de los estudiantes sobre el papel de la gramática en la enseñanza de idiomas; ii) organizamos un grupo focal para aclarar determinadas opiniones que son difícilmente entendibles solamente por medio de información cuantitativa. Asimismo, presentamos los principios fundamentales de su formación idiomática actual basada en mecanismos cognitivos de asimilación inconscientedel inglés según la enseñanza adquisitiva (Haidl, 1993, 1995) de leguas extranjeras, la cual evita la presentación explícita de reglas y normas gramaticales. Los resultados muestran opiniones similares entre los informantes, sobre todo para cuestionamientos relacionados con una formación que solo contemplaba el estudio formal de la gramática de la lengua meta. Asumen que sus pensamientos están fundamentados en una forma única de entender la enseñanza de idiomas que, además, coincide con la experimentada en primera persona durante etapas preuniversitarias: la instrucción formal. Con todo, a partir de la investigación-acción, parecen también acoger con satisfacción las posibilidades que brinda la enseñanza adquisitiva.

Geology at the Lower Secondary Educational Level (ISCED 2): Comparison of the Czech Republic, Estonia, Slovenia and Poland
Authors: Jedličková Tereza , Svobodová Andrea , Kachlík Václav
Published: December 2019

Geology is a science with a highly interdisciplinary character. Thus, in education it is ideal to provide education in a form integrated with the other branches of natural sciences under the subject of Science or Natural Sciences. However, most European countries prefer separate teaching of the individual educational fields and subsume geology within one of them, most frequently biology or geography. The submitted study discusses the potential advantages and disadvantages of various strategies of allocation of geological topics in education. A comparative method is used to evaluate and analyse curricular documents in the Czech Republic, Estonia, Slovenia and Poland at the lower secondary educational level. The comparison is focused on the scope and incorporation of selected educational content of geology into individual educational subjects, and on the recommended teaching methods suitable for interpreting geological subject matter. On the basis of this knowledge from abroad, individual subjects are selected for the “best practice” and subsequently proposed for implementation under the conditions in the Czech Republic. This seeks to make geology more familiar and attractive for students at the lower secondary level of education.

Published: December 2019

Background: Patients with chromosome 18 abnormalities can present with an immune phenotype that resembles common variable immunodeficiency. Knowledge of the genes underlying the immune defects related to chromosome 18 aberrations could improve our understanding of the molecular basis of primary antibody deficiencies. Here we present a patient with ring chromosome 18 affected by primary antibody deficiency and autoimmunity.

Methods: Lymphocyte populations were determined by flow cytometry. Specific antibody response to protein vaccines and pneumococcal capsule antigen were measured by ELISA. Genome sequencing was performed using a PCR-free protocol.

Case: The patient was diagnosed with ring chromosome 18 for delayed growth and dysmorphic features at the age of 1 month. Array comparative genomic hybridization showed deletions of 18p11.21-pter and 18q21.31-qter. At the age of 10 months, she started having recurrent episodes of otitis media and pneumonia, as well as autoimmune arthritis. Serum immunoglobulins and specific antibody levels were low. The CD19+CD27+ memory B cell and CD45RO+ T cell populations were decreased. Recurrent infections were controlled with parenteral immunoglobulin and autoimmune arthritis was treated with systemic and intra-articular therapies.

Conclusions: Selective IgA deficiency is the most common form of immunodeficiency associated with chromosome 18 abnormalities, however patients with ring chromosome 18 may also be affected by specific antibody deficiency and require immunoglobulin replacement for optimal care. These patients might partially share the same genomic loss as in patients with non-syndromic primary antibody deficiency.

Statement of novelty: This report highlights an important teaching point about immune deficiency in a chromosomal anomaly that is not infrequently encountered in pediatric hospitals. Furthermore, our investigations provide more insight into the pathogenesis of immunodeficiency among patients with chromosome 18 abnormalities.
Luminescence chronology of fluvial and marine records from subsurface core in Kaveri delta, Tamil Nadu: Implications to sea level fluctuations
Authors: Goswami Kartika , Krishnan Sivakumar , Kumerasan Anbarasu , Sadasivam Senthil Kumar , Kumar Pankaj , Jaiswal Manoj. K.
Published: December 2019

South-Eastern coastal plains of India experience some of the major delta formations of the Indian subcontinent majorly affected by fluctuations of the Indian summer monsoon (ISM) and sea level. Past shoreline signatures in the form of palaeo beach ridges in Kaveri delta (Tamil Nadu, India), suggest a wave-dominated delta and thus past sea-level variations affecting directly the sedimentary dynamics of the Kaveri river forcing the river to either aggrade or prograde. Chronostratigraphic and foraminiferal study of the 25 m deep sediment core taken 2.5 km onshore from Tamil Nadu coast, Kaveri delta shows evidence of changing coastline over the last 150 ka. Various units in the core reflect eight major phases of increased sea level (~3.4 ka, ~5.0 ka, 9–6 ka, 60–57 ka, 89–81 ka, ~102 ka,~121 ka and 143–140 ka) partly coinciding with the global climate cycles MIS 1, MIS 3, MIS 5, MIS 6 respectively during the late Quaternary period. During ~121 ka and 9–6 ka, direct signature of marine transgression is observed by the presence of foraminifera in the core location. The study also shows that the sea transgression during ~121 ka was much longer-lasting and higher than during 9–6 ka, even though not revealed in the Quaternary sea level curve given by previous authors. Depositional breaks are observed in the core during periods of lower sea levels as the river responded by incision. Total organic matter of the deposition between 9–6 ka was observed as high as 2.5–6% suggesting oxygen stressed conditions during the period.
Mental Imagery in Volleyball Settings: A Scoping Review
Authors: Ribeiro Joana , Dias Cláudia , Filho Valter Cardoso Barbosa , Cruz José , Fonseca António
Published: December 2019

This article presents a scoping review of the published literature on mental imagery in the context of volleyball. Four online databases and one peer-reviewed journals were searched, based on the inclusion criteria. Publication information, procedures and research methods, sample characteristics, sport type and type of mental imagery were analyzed. The selection process found 52 studies, and results showed that from 1987 to 2018 the mental images, along with other psychological skills, have gained popularity in volleyball settings. The examined studies used cross-sectional and experimental approaches, and the analysis was assessed by quantitative data and/ or mental imagery training programs (with relaxation and scripts), mainly focusing on the isolated analysis of the mental imagery construct, and evaluating its use. The studies included both male and female participants, but only 11% were volleyball players. Additionally, the focus was on adolescents and young adult athletes, mostly from high school/ university or international/ elite levels. However, just two studies examined athletes under the age of 16. Considering the present study’s results, limitations, and its implications for practice (e. g. to provide the coach certification programs with specific mental imagery contents), future research directions were highlighted, such as improve mental imagery training programs for children and youth volleyball players.

Teenage Agency and Popular Music Reception in World War II-Era Frank Sinatra Fan Clubs
Authors: Hollenbach Katie Beisel
Published: December 2019

During World War II, American media consistently portrayed the typical young female Frank Sinatra fan as a disinterested citizen who failed to devote adequate attention to the war effort and harbored an inappropriate obsession with the pop idol. What contemporaneous critics and current scholars have generally not acknowledged, however, was how Sinatra fandom allowed thousands of American teenage girls to navigate their stressful, confusing, and often contradictory wartime realities with purpose and enthusiasm. This article examines wartime Frank Sinatra fan clubs through the lens of fan club newsletters and correspondences, which were authored, printed, and distributed entirely by the primarily teenage female members of these clubs. In contrast to professionally published press coverage and criticism, these fan-made texts provide unprecedented insight into how this specific fan community used their adoration of Sinatra as a base to explore international relationships, develop professional skills, and engage in personal expression amidst heightened feelings of nationalism and conflicting expectations regarding American gender roles.
Él Es Chicano?
Authors: Davila Richard Cruz
Published: December 2019

This article considers questions of authenticity in two versions of Doug Sahm's “Chicano”: Sahm's original, recorded with the Sir Douglas Band in 1973, and Rumel Fuentes's 1976 cover version. Some critics and listeners considered Sahm's original, written from a first-person Chicano perspective, a gaffe, since Sahm was in fact not Chicano; however, employing Allan Moore's notion of authenticity as authentication, I argue that Fuentes's cover version is at once an endorsement of Sahm's original and an authentication of it. To do so, I begin by elaborating Moore's three-part typology of authenticity, and how this typology recasts authenticity as authentication. I then place Sahm's appropriation of a Chicano identity within a longer history of racial crossing in American popular music before providing historical context for each artist, and for each version of the song. Finally, by discussing the two versions in terms of Moore's typology, I argue that the cover authenticates the original through what Moore calls second-person authenticity, which he describes as a validation of the listener's experience.
O Leão, o Coelho e a Garota de Ipanema: Ondjaki reescreve conto angolano de tradição oral

Authors: Castro-González Sandra , Bande Belén
Published: December 2019

A pesar del progresivo aumento de estudios sobre responsabilidad social corporativa (RSC), el estudio de sus antecedentes y de su influencia sobre las actitudes y comportamientos de la fuerza de ventas es todavía limitado. Este trabajo contribuye a llenar este vacío en la literatura organizativa, de comportamiento sostenible y de ventas mediante el análisis de cómo el ejercicio del liderazgo ético por parte del supervisor puede influir a través de la percepción responsabilidad social corporativa y la satisfacción laboral en el desempeño de los vendedores. Los resultados obtenidos del análisis mediante procesos condicionales de una muestra de 120 díadas de supervisores-vendedores confirman que el liderazgo ético está relacionado positivamente con el desempeño del vendedor, pero a través de un mecanismo mediador en el que intervienen sus percepciones de RSC y su satisfacción laboral. Además, el trabajo también analiza las principales implicaciones para la gestión y propone futuras líneas de estudio.
The agricultural and agri-food sector in Galicia; assessment of changes from European integration, 1986-2016
Authors: López-Iglesias Edelmiro
Published: December 2019

In the last 30 years, the Galician agricultural and agri-food sector has had to face deep changes in its operating environment, as a result of changes in markets, policies and societal demands. In that context, the sector has shown in some aspects a remarkable dynamism and response capacity. Examples include the growth of milk production, which allowed Galicia to consolidate its position among the top ten dairy regions of the EU, or the development of differentiated and quality productions, mainly in beef and wine. With regard to production technology, the agricultural sector maintained a high investment effort which, coupled with the accelerated decrease in labor, made it possible to correct the low rate of capital per worker. This investment effort also allowed the consolidation of a set of medium-sized professional holdings, still minority in number but already the productive core of the sector. However, despite the advances, the agri-food chain continues to register strong deficiencies, especially in two aspects: structural deficits in the land base of farms and land uses, and the weakness of the agroindustry. Deficiencies that have caused an increase in the deficit of the agri-food trade balance in the last three decades.

Authors: Rodríguez-Gulías María Jesús , Martíns Julio Paulo , Rodeiro-Pazos David
Published: December 2019

Science and technology parks are considered an essential tool of the Regional Innovation System. For this reason, this paper analyzes the business financial and innovation features of the companies based in science and technology parks in the GaliciaNorthern Portugal Euroregion. Companies based in Galician parks are older and larger in terms of turnover and employment, while there are more companies based in Portugal providing intensive services in high-tech skills and exportation. The level of patents is low for both of them.
O psicodrama brasileiro na próxima década
Authors: Junqueira Fleury Heloisa
Published: December 2019

O psicodrama chegou no Brasil após algumas tímidas iniciativas, mas só foi de fato apresentado ao público brasileiro com a realização do V Congresso Internacional de Psicodrama e o I Congresso Internacional de Comunidades Terapêuticas, ocorrido no Museu de Arte de São Paulo (MASP) em 1970. Os participantes encantaram-se com a ampliação do potencial terapêutico dessa nova proposta de trabalho, inclusive com grupos, o que transformou as referências em psicoterapia.

It’s More than Just Religion: Teaching History in a Catholic
School
Authors: Fitzpatrick Colleen
Published: December 2019

This study explores how one teacher, Rebecca, makes sense of teaching
history in a Catholic school. This Catholic school had a clear religious
mission and did not have required curriculum or high-stakes tests. Yet,
findings indicate that Rebecca did not attend to the religious mission in
her teaching and, in absence of curricula or high-stakes tests, she relied
heavily on the textbook. Findings demonstrate the need for a greater
understanding of what curricular content is being taught and learned in
Catholic elementary and secondary schools and how it aligns with the mission
and purpose of Catholic schools.
Role of parabolic viscosity in numerical analysis of derivative nonlinear evolution equations
Authors: Meškauskas Tadas , Ivanauskas Feliksas
Published: December 2019

We consider the difference schemes applied to a derivative nonlinear system of evolution equations. For the boundary-value problem with initial conditions

∂u/∂t = A ∂2u/∂x2 + B ∂u/∂x + f(x,u) + g(x,u) ∂u/∂x,    (t,x) ∈  (0, T] x (0, 1),u(t,0) = u(t,1) = 0,    t ∈ [0, T],u(0,x) = u(0)(x),    x ∈ (0, 1)

we use the Crank-Nicolson discretization. A is complex and B – real diagonal matrixes; u, f and g are complex vector-functions. The analysis shows that proposed schemes are uniquely solvable, convergent and stable in a grid norm W22 if all (diagonal) elements in Re(A) are positive. This is true without any restriction on the ratio of time and space grid steps.

Published: December 2019

The aim of this paper is to show how the theory of systems of differential equations may be applied both to describe the battle actions and to control the trajectory of projectiles. We will restrict our attention to deterministic cases. Those cases are not well adapted to the real situation and must be treated as the first approach.
Dynamics of the processes in metal machining
Authors: Švitra Donatas , Janutėnienė Jolanta
Published: December 2019

In the practice of processing of metals by cutting it is necessary to overcome the vibration of the cutting tool, the processed detail and units of the machine tool. These vibrations in many cases are an obstacle to increase the productivity and quality of treatment of details on metal-cutting machine tools. Vibration at cutting of metals is a very diverse phenomenon due to both it’s nature and the form of oscillatory motion.

The most general classification of vibrations at cutting is a division them into forced vibration and autovibrations. The most difficult to remove and poorly investigated are the autovibrations, i.e. vibrations arising at the absence of external periodic forces. The autovibrations, stipulated by the process of cutting on metalcutting machine are of two types: the low-frequency autovibrations and high-frequency autovibrations. When the low-frequency autovibration there appear, the cutting process ought to be terminated and the cause of the vibrations eliminated. Otherwise, there is a danger of a break of both machine and tool. In the case of high-frequency vibration the machine operates apparently quiently, but the processed surface feature small-sized roughness. The frequency of autovibrations can reach 5000 Hz and more.
Modelling of wood drying and an influence of lumber geometry on drying dynamics
Authors: Baronas R. , Ivanauskas F. , Sapagovas M.
Published: December 2019

Modelling of wood drying is analyzed. Wood drying involves moisture transfer from the interior of the wood to the surface, then from the wood surface to the surrounding air. These processes can be characterized by the internal and surface moisture transfer coefficients. A model of the two-dimensional moisture transfer is suggested to determine these coefficients in contrast to the one-dimensional model which was proposed in [12]. The model is based on a diffusion equation with a variable diffusion coefficient. The insufficiency of the one-dimensional model is considered. The influence of the geometry of a lumber on determination of the surface emission and diffusion coefficients and on the dynamics of drying is investigated.

A well-implemented and adequately funded medical home not only is the best approach to optimize the health of the individual patient but also can function as an effective instrument for improving population health. Key financing elements to providing quality, effective, comprehensive care in the pediatric medical home include the following: (1) first dollar coverage without deductibles, copays, or other cost-sharing for necessary preventive care services as recommended by Bright Futures: Guidelines for Health Supervision of Infants, Children, and Adolescents; (2) adoption of a uniform definition of medical necessity across payers that embraces services that promote optimal growth and development and prevent, diagnose, and treat the full range of pediatric physical, mental, behavioral, and developmental conditions, in accord with evidence-based science or evidence-informed expert opinion; (3) payment models that promote appropriate use of pediatric primary care and pediatric specialty services and discourage inappropriate, inefficient, or excessive use of medical services; and (4) payment models that strengthen the patient- and family-physician relationship and do not impose additional administrative burdens that will only erode the effectiveness of the medical home. These goals can be met by designing payment models that provide adequate funding of the cost of medical encounters, care coordination, population health services, and quality improvement activities; provide incentives for quality and effectiveness of care; and ease administrative burdens.
