Hong Kong (short films)

Published: August 2019

COMING-OF-AGE OF HONG KONG'S INDEPENDENT SHORT FILMS An interesting phenomenon as a result of Hong Kong's handover to China in 1997 was a profusion of innovative short films by young directors who worked mostly in video. Their "shoot-on-the-run" films, made on shoestring budgets, documented the anxieties and opinions of the ordinary Hong Konger about the colony's return to the mainland. Ten of these shorts, ranging from 5 to 30 minutes, were shown at the 22nd Hong Kong International Film Festival (HKIFF) in 1998 under the title 'Digital Biography of Hong Kong, Progams I & II'. The 'digital diaries', as these videos were called, were commissioned by the Japanese producer Mio Hani and Stella Sze. Program I offered Howard Cheng's fragmented, two-part, experimental video, The Daily Mood of Final Certainty or The House of August, about 5 characters.

TOPOGRAPHIES OF DEFEAT: MASCULINITY AND DESOLATION IN FAT CITY AND JUNIOR BONNER         Success stories, per se, are not really of much interest to me       (John Huston) In  1972,  two of Hollywood's most independent filmmakers -- John Huston and Sam Peckinpah -- directed two pensive, deceptively inconspicuous movies which probed the existential malaise afflicting a particular form of American masculinity. Fat City(1) -- Huston's first American film in more than a decade -- was released to much critical acclaim, and reviewers came to rank it alongside his best previous efforts like The Maltese Falcon (1941), The Treasure of the Sierra Madre (1948), The Asphalt Jungle (1950) and The African Queen (1951).(2) Commercially, however, it was a modest failure.(3) With Junior Bonner, Peckinpah thoroughly defied the anticipations of critics and spectators who expected (and craved?) another cinematic blood orgy like the one in The...

Berlinale 2001 Report
Authors: Holloway Ron
Published: August 2019

INTERNATIONAL FILM FESTIVAL BERLIN 2001 IT fit the 2001 Berlinale (7-18 February 2001) like a glove: Stanley Kubrick's 2001 -- A Space Odyssey as the closing night presentation. For back at the 1981 Berlinale, when Martin Scorsese delivered a fiery, passionate lecture on "Color Fading," he cited 2001 in particular to underscore the dilemma of colour preservation. Thanks to his efforts, and those of dedicated film archivists, Stanley Kubrick's 2001: A Space Odyssey (1968) has now been restored to its original pristine colour photography -and was the undeniable hit of the Berlinale. When one recalls that Berlinale director Alfred Bauer had laboured far into the night to book Kubrick's 2001 for the 1968 festival -- a failed effort now fulfilled -- this made for a particularly poignant evening. Stanley Kubrick's widow attended the screening, together with his brother-in-law Jan Harlan, whose documentary Stanley Kubrick: A Life in Pictures was...
Identical Twins x 3
Authors: Warchol Tomasz
Published: August 2019

CINEMA IS ABOUT creating images in motion. It reflects the essential denotation of an image as an optical reproduction of an object, scene, movement, gesture. It's about visual representations of our perceptions and ourselves. It's a medium through which directors project their visions, actors reincarnate themselves in ever new impersonations, and viewers watch the screen images as reflections of mimetic (or fantastic) reality. So far, it has been technology's greatest gift to the human imagination, a remarkable mirror of life-like illusions. Filmmakers naturally exploit cinema's fundamental reproductive nature, its inherent double-ness, often deliberately exploring questions of identity and reliability of our perceptions and judgements to engage us in fascinating games of visual deception and intellectual manipulation. Those themes typically involve mistaken identities, lookalikes, impostors, and alter egos, as well as incubi and body snatchers in their horror and sci-fi varieties. The protagonists live double (as in, say, Europa, Europa...
The Film Studies Dictionary
Authors: Uhde Jan
Published: August 2019

SEMANTIC VAGUENESS has been a typical feature of cinema's professional terminology and taxonomy, a problem which exists both in the academic circles of film studies and among film-makers themselves. Moreover, it is amplified by fashionable but meaningless jargon of some film reviewers and commercial newspeak, the intention of which is often disinformation in the first place. Over the past decades, a few attempts have been made to improve this situation through the publication of film term glossaries and dictionaries, including Geduld-Gottesman's An Illustrated Glossary of Film Terms (1973), S. E. Browne's Film-Video Terms and Concepts (1992) and F. Beaver's Dictionary of Film Terms (1994). A major difficulty facing film dictionary writers has been whether to aim at the practical filmmaker or academic theorist; uniting these two user groups has not always been successful. Another problem plaguing some of these reference publications has been that the entries did not go beyond...
The Films of Atom Egoyan
Authors: Mazierska Ewa
Published: August 2019

INSTITUTIONS AND INDIVIDUALS IN THE FILMS OF ATOM EGOYAN The majority of Atom Egoyan's films are set in contemporary Canada, a country regarded as one of the most civilised in the industrialised world, famous for its affluence, good working conditions, relative social equality and excellent standard of social welfare. ‘Egoyan's Canada' conforms to this picture, as his characters usually enjoy a comfortable and economically secure existence. In spite of comfort and affluence, they rarely give the impression of being happy. On the contrary, they seem to be unfulfilled, emotionally constrained, as well as suffering other problems associated with the dark side of the ‘postmodern condition'.(1) The purpose of this article is to discuss their situation as an illustration and critique of this condition. Institutions in private livesOne of the features of their lives is domination by institutions, which dictionaries define as ‘organisations or establishments, founded for specific purposes'....
The Discourse of the Absent Body
Authors: Williams Bruce
Published: August 2019

WITHOUT HABEAS CORPUS: THE DISCOURSE OF THE ABSENT BODY As the Twin Towers collapsed into a cloud of dust covering Lower Manhattan on September 11, 2001, the corporal remains of several thousand people evaporated with them - cremated and scattered in a matter of seconds. Bodies vanished, nameless, and families were denied closure, a place to grieve. This event, unique in the history of the United States precipitated an equally unprecedented period of national mourning, unprecedented in its lack of finality. At memorial services throughout the nation, obviously dead victims were described as "missing" for lack of a better term. This tragedy recalls the lack of closure suffered by families of the "disappeared persons" of Chile and Argentina, who likewise have experienced an aborted grief process.(1) As Chilean human rights activist Marjorie Agosín has stated in Andrew Johnson's documentary film, Threads of Hope, the presence of the body in...
Singapore International Film Festival 2002
Authors: Wee Brandon
Published: August 2019

The SIFF celebrated its fifteenth birthday in typical festival frenzy. Seguing into another year, the event drew intense emotions from persistent mechanical glitches and over-air-conditioned halls but also from the pleasure of having been gratified by grand moving images. Some 390 films from 40 countries shaped the spread, with spotlights on contemporary fixations: The theme of "globalisation" had an exclusive programme dedicated to filmmakers' representations of this loaded buzzword. Another catch phrase, Digital Cinema, was given further resonance with the introductory Asian Digital Film Awards plus a medley of international features 'digitised' by the proselytising logic of economy and portability. Another favourite was animation, with the invisible world of Asian animations taking centre stage, and also tributes to manga guru Tezuka Osamu and Jan Å vankmajer, a man who begrudges the animator label.Kandahar (2001), Mohsen Makhmalbaf's prescient essay on humanity opened the festival to little surprise.

Un cuarto de siglo de investigación genética en los trastornos neuropsiquiátricos en Costa Rica
Authors: Bolaños-Palmieri Patricia , Chavarria-Soley Gabriela , Contreras Javier , Raventós Henriette
Published: August 2019

Abstract: A quarter century of genetic research on neuropsychiatric disorders in Costa Rica. In Costa Rica, the study of the genetic basis of neuropsychiatric disorders started more than 25 years ago. During this time, different research efforts have focused on several disorders: schizophrenia, bipolar disorder, Alzheimer’s disease, obsessive-compulsive disorder, attention deficit/hyperactivity disorder, and Tourette syndrome. The studies have had a wide scope regarding design (linkage/association), sample used (families/sib pairs/trios), genome coverage (candidate gene studies/genome-wide scans), and phenotype definition (diagnostic category/ syndromic classification/endophenotype). Here we present a summary of the main genomic findings of these multidisciplinary studies, and discuss the importance, lessons, and challenges of genetic research of complex psychiatric disorders.
Shade tolerance within the context of the successional process in tropical rain forests
Authors: Avalos Gerardo
Published: August 2019

Shade tolerance (the capacity to survive and grow over long periods under shade) is a key component of plant fitness and the foundation of current theories of forest succession in tropical rain forests. It serves as a paradigm to understand the optimal allocation of limited resources under dynamic light regimes. I analyze how tropical rain forest succession influences the expression of ecophysiological mechanisms leading to shade tolerance, and identify future areas that will increase our understanding of the ecological and evolutionary consequences of this phenomenon. Shade tolerance is a multivariate, continuous functional trait reflecting the growth-mortality trade-off of investing resources under limited light vs. exploiting high light conditions. I propose the life cycle successional trajectory model of Gómez-Pompa & Vázquez-Yanes as an integrative tool to understand tropical rain forest succession. This model shows how species distribute along the successional environmental gradient based on their degree of shade tolerance and represents a more integrative paradigm to understand the interface between different aspects of species diversity (ontogenetic variation and functional diversity) throughout succession. It proposes that different trait combinations determining shade tolerance are expressed at different stages of the life cycle, which affects how and when plants enter the successional trajectory. Models explaining the expression of shade tolerance (resource availability, carbon gain, CSR, resource competition) are based on whole-plant economics and are not mutually exclusive. The analysis of shade tolerance is biased towards tree seedlings in the understory of mature forests. Other life stages (juvenile and adult trees), life forms, and microhabitats throughout the forest profile are almost always excluded from these analyses. More integrative explanations based on the distribution of functional traits among species, ontogenetic stages, and the nature of the environmental gradient are being developed based on long-term data and chronosequence comparisons. In summary, shade-tolerance is a complex phenomenon, is determined by multiple characters that change ontogenetically over space and time and entails considerable plasticity. Current methods do not account for this plasticity. Understanding the nature of shade tolerance and its functional basis is critical to comprehending plant performance and improving the management, restoration and conservation of tropical rain forests given the combined threats of global warming and habitat loss
Germinación de semillas de Crescentia alata (Bignoniaceae) en distintas condiciones de temperatura, luminosidad y almacenamiento
Authors: Valverde-Rodríguez Kimberly , Morales Carlos-O. , García Elmer-G.
Published: August 2019

Crescentia alata (Bignoniaceae) es una especie arborescente de gran interés cultural y económico desde México hasta Costa Rica. Sin embargo, la protección de las poblaciones naturales y el establecimiento de plantaciones son limitados por la carencia de información sobre germinación de semillas y crecimiento de plántulas. Este estudio pretende caracterizar los frutos y las semillas, evaluar el proceso de germinación a diferentes temperaturas y niveles de luminosidad, y determinar las condiciones óptimas de temperatura, humedad y almacenamiento para mantener viables las semillas. Se midieron altura, diámetro y masa de frutos, así como largo, ancho y masa de semillas; además, se contó el número de semillas por fruto. Asimismo, se evaluó el porcentaje de germinación a cinco temperaturas (15, 20, 30, 20-30 y 25-30 °C), en condiciones de luz-oscuridad, con almacenamiento a tres temperaturas (5° C, 15 °C y ambiente: 22-24 °C) durante 36 meses. También se observó la viabilidad de las semillas conservadas dentro del fruto. El valor promedio del índice de redondez (IR) fue -1.86; esto indica que los frutos son redondeado-achatados. En promedio el fruto midió 7.90 ± 2.58 cm de altura y 9.62 ± 1.21 cm de diámetro; las semillas midieron 0.75 ± 0.07 cm de largo y 0.67 ± 0.05 cm de ancho. La masa promedio del fruto fue 414.57 g y cada fruto tuvo en promedio ca. 691 semillas, que no germinaron a 15 °C ni a 20 °C; en la oscuridad disminuyó la germinación y la viabilidad de las semillas se redujo cuando se almacenaron a temperatura ambiente (22-24 °C) y cuando permanecieron dentro del fruto. Los resultados indican que las semillas de C. alata germinan mejor a 30 °C, en condiciones de luz y separadas de la pulpa del fruto antes de almacenarse; además, almacenadas a temperaturas bajas (5 °C y 15 °C) los porcentajes de germinación y la viabilidad se mantienen altos (ca. 90 %) hasta por tres años. Estos datos pueden contribuir a mejorar el almacenamiento de semillas y la obtención de plántulas para propagación; así podría aumentar el tamaño de las poblaciones con fines económicos o de conservación, lo que favorecería tanto a la especie estudiada como al bosque tropical seco en que habita.
Efecto del almacenamiento ex situ de semillas y de condiciones lumínicas sobre la tasa de crecimiento de plántulas de Crescentia alata (Bignoniaceae)

Published: August 2019

En el bosque tropical seco, el árbol Crescentia alata (Bignoniaceae) es un recurso cultural y económico, pero han fracasado algunos intentos para establecer plantaciones, que podrían satisfacer la producción comercial y, así, evitar el impacto en las poblaciones naturales. Por tanto, existe la necesidad de generar información biológica sobre esta especie para obtener plantas en condiciones de invernaderos. El objetivo de este trabajo fue evaluar la tasa de crecimiento de plantas de C. alata obtenidas de semillas que se almacenaron en diferentes períodos y a varias temperaturas, y determinar el efecto de la intensidad de la luz sobre el crecimiento de las plántulas. Se recolectaron frutos en Liberia (Guanacaste, Costa Rica) y se almacenaron semillas por 0, 4, 8 y 14 meses a 5 °C, 15 °C y a temperatura ambiente (22-24 °C). Las plántulas de las semillas almacenadas por 0, 4, 8 y 14 meses se trasplantaron para evaluar el crecimiento después de 8 días, 2 y 16 meses, y en dos condiciones de luminosidad. La morfología de las plántulas de 8 días cambió según el tiempo de almacenamiento. El análisis de componentes principales de la evaluación de 2 meses indica que las variables más significativas fueron biomasa total seca, biomasa seca de hojas, de raíz-vástago, de tallo y de raíz, mientras que en el análisis de la evaluación de 16 meses tales variables fueron biomasa seca de raíz, de raíz-vástago y de hojas, también número de hojas y longitud del vástago. El área foliar específica de plantas con 16 meses de edad obtenidas de semillas almacenadas 14 meses no cambió con la temperatura de almacenamiento. Además, dos condiciones de luminosidad influyeron en la altura, el diámetro del tallo o el número de hojas. El almacenamiento de semillas a 5 °C y 15 °C favoreció el desarrollo de los cotiledones, así como la longitud de la raíz y del hipocótilo. Plantas de 2 meses obtenidas de 0 y 8 meses asignaron mayor biomasa a raíces que a tallos, mejorando así la absorción de agua. Plantas de 16 meses provenientes de semillas no almacenadas desarrollaron el mayor número de hojas, y aquellas de semillas de 8 meses a 5 °C y 15 °C mostraron tallos más cortos. Las semillas almacenadas hasta 14 meses se convirtieron en plantas bien desarrolladas. Se recomienda a futuros investigadores evaluar la viabilidad a diferentes temperaturas de secado de las semillas y en niveles de intensidad lumínica más contrastantes durante el crecimiento.
Variación en la actividad acústica de Hyalinobatrachium fleischmanni (Anura: Centrolenidae) en un ambiente urbano con diferentes niveles de ruido antropogénico

Las señales acústicas producidas por animales pueden ser enmascaradas por el ruido del medio ambiente en que se encuentran, tanto de origen natural como antropogénico. Una especie que puede ver afectada su comunicación por el ruido medio ambiental es la rana de vidrio Hyalinobatrachium fleischmanni (Centrolenidae), porque la distribución actual de esta especie en gran parte se encuentra en ambientes urbanos con altos niveles de ruido. En este trabajo analizamos si existe una relación entre la variación de los niveles de ruido antropogénico a través de la noche y la actividad vocal (cantidad de vocalizaciones por unidad de tiempo) de H. fleischmanni, a lo largo de un gradiente de ruido urbano. El trabajo lo realizamos en tres sitios dentro del Campus Universitario Rodrigo Facio, San José, Costa Rica durante el mes de junio de 2015. Para contabilizar la actividad vocal de la especie en cada sitio instalamos grabadores programables de 17:00 a las 6:00 por dos días consecutivos cada dos semanas. De forma simultánea, cuantificamos el ruido en dB cada hora a lo largo del periodo de grabación utilizando sonómetros. Comparamos la abundancia promedio de vocalizaciones por hora contra los niveles de ruido promedio por hora y sitio utilizando modelos lineales mixtos. Nuestros resultados demuestran que, tanto el ruido como la actividad vocal de H. fleischmanni variaron a lo largo de la noche. Sin embargo, encontramos que en el sitio más ruidoso el patrón de actividad de H. fleischmanni difiere de los dos sitios menos ruidosos.El sitio menos ruidoso fue el que presento una mayor actividad vocal a lo largo de todo el periodo de muestreo. A pesar de que no se encontró una relación directa entre el nivel de ruido antropogénico y la actividad acústica de H. fleischmanni, sí observamos un efecto de los niveles de ruido en los patrones de actividad de la especie.

A method for rapid quantitative imaging of dopant distribution using secondary ion mass spectrometry (SIMS) is described. The method is based on SIMS imaging of the cross-section of a reference sample with a known concentration profile. It is demonstrated for the case of boron quantification in silicon in a SIMS imaging mode. A nonlinear relationship between the secondary ion intensity and the concentration is observed. A detection limit of 3 (±2) × 1017 at./cm3 (~6 ppm) is determined with 39 nm pixel-size for the used experimental conditions. As an application example, a boron concentration profile in a passivating contact deposited on a textured Si surface is analyzed.

BEET CULTIVATION UNDER DIFFERENT SOIL WATER TENSIONS

 

 

2 ABSTRACT

 

The objective of this study was to evaluate the effect of different soil water stresses on beet production, cultivated in a protected environment and irrigated by drip irrigation, to establish criteria for proper irrigation management. The experiment was conducted in the experimental area of the Engineering Department of the Federal University of Lavras (UFLA), from February to May 2016. The innovative design was a randomized complete block (DBC), with six treatments and four replications. The treatments consisted of six soil water tension stresses (15, 25, 35, 45, 55 and 65 kPa). From the results obtained, it was concluded that to achieve higher values of productivity and efficiency in the use of water, irrigations should be carried out when the water tension in the soil is around 15 kPa, to a depth of 0.15 m.

Sobre a inconstância da alma cordial: presença e ausência ameríndia em Raízes do Brasil
Authors: Jobim Martins André
Published: August 2019

Em Raízes do Brasil (1936), Sérgio Buarque de Holanda atribui à cultura ibérica o protagonismo exclusivo na gênese do estilo de vida e pensamento predominante no Brasil, sintetizado na imagem do “homem cordial”. Este ensaio argumenta que a cultura ibérica, tal como descrita no livro, não se conforma perfeitamente à dimensão intelectual da cordialidade. O “homem cordial” é reexaminado à luz das reflexões de Eduardo Viveiros de Castro sobre a “inconstância” tupinambá, no sentido de propor que certos traços dessa cultura tornam mais compreensível a análise que Sérgio Buarque faz da mentalidade brasileira. A pertinência da hipótese é demonstrada a partir do realce de mudanças ocorridas no texto entre suas duas primeiras edições (1936 e 1948), relacionadas à caracterização da cultura portuguesa e da sua interação com as culturas ameríndias, e de um exame daquilo que se poderia considerar uma inconstância do intelecto no capítulo “O homem cordial”, em cotejo com as leitura que Oswald de Andrade faz de Raízes num ensaio de 1950.
La recepción de la historia de conceptos en España. En la encrucijada entre la reflexión teórica y la aplicación práctica
Authors: Fernández Torres Luis
Published: August 2019

En este trabajo se aborda una suerte de historia de la historia de conceptos desarrollada por Reinhart Koselleck. En concreto, se procura trazar su periplo en el mundo académico español, incorporando los inicios de su recepción, los resultados materiales de la aplicación de su propuesta y un esbozo de los grupos de investigadores que han aprovechado críticamente su obra. En este sentido, destacan especialmente dos perfiles, que se corresponden con filiaciones académicas distintas: una vertiente vinculada a la filosofía y otra de corte historiográfico, que reflejan, a su vez, la riqueza de una obra como la koselleckiana, en la que conviven elementos procedentes de distintas disciplinas, como la filosofía, la lingüística y la historia, entre otras. Esta diversidad de componentes se manifiesta en la constitución de un potente cuerpo teórico en combinación con un elaborado aparato metodológico.
A crítica historiográfica no Brasil nos anos 1990 e o espectro do linguistic turn: embates entre “modernos” e “pós-modernos”
Authors: Dos Santos Wagner Geminiano
Published: August 2019

Neste artigo, discutimos como a crítica historiográfica, no Brasil, fez da linguistc turn um espectro a assombrar os territórios e fronteiras disciplinares de Clio, ameaçando o ofício dos historiadores profissionais, acadêmicos. Penso isso a partir de um suposto debate ocorrido em 1993, por ocasião dos 20 anos do Centro de Pesquisa e Documentação de História Contemporânea do Brasil, CPDOC, da Fundação Getúlio Vargas, entre dois expoentes dos debates que orbitavam a “virada linguística” e suas implicações para o fazer do historiador, Hayden White e Roger Chartier. Os textos de ambos, publicadas em 1994, na edição comemorativa da Revista Estudos Históricos – REH, servirão de modelo para os debates teórico-metodológicos que os historiadores profissionais, acadêmicos, sobretudo aqueles que se arvoravam como críticos historiográficos, iriam estabelecer dali por diante, em especial quando estavam avaliando o “estado da arte” no país. Esse debate reverberou ao longo dos anos 1990 e 2000 nas discussões que opuseram “modernos” e “pós-modernos”, e na configuração da geografia e da memória disciplinar do saber histórico no Brasil.
Tempo do evento, poética da história: maio de 1968 segundo Michel de Certeau e Cornelius Castoriadis
Authors: Marcelino Douglas Attila
Published: August 2019

Este artigo analisa e estabelece comparações entre as interpretações de Michel de Certeau e Cornelius Castoriadis sobre as manifestações de maio de 1968. São privilegiados os escritos produzidos por ambos os autores na própria conjuntura do evento, não obstante relações com textos posteriores também sejam realizadas. Por meio da análise desses materiais distintos, sugere-se a relevância dos acontecimentos de 1968 para a formulação de algumas ideias-chave dos dois autores, sobretudo no que diz respeito ao significado conferido ao evento como o surgimento do novo, do inesperado, do impensável. Essa valorização da radical novidade das ocorrências de maio se relacionava com pressupostos ontológicos sobre a temporalidade da história como experiência vivida, mas também incidia sobre os fundamentos epistemológicos da história como forma de escrita. Suas análises, portanto, permitem explorar importantes implicações teóricas, políticas e até mesmo poéticas do significado conferido ao evento pela historiografia.
Falando de Virtudes e Estabelecendo Fronteiras na Historiografia Brasileira Moderna: uma leitura de Historiadores do Brasil, de Francisco Iglésias
Authors: Ohara João Rodolfo Munhoz
Published: August 2019

Em Historiadores do Brasil, Francisco Iglésias avalia alguns dos grandes nomes da historiografia brasileira, dividindo-os em três momentos distintos: o primeiro, até 1838; o segundo, de 1838 a 1931; e o terceiro, de 1931 adiante. Este artigo focará no terceiro desses momentos, o qual tem sido tratado como o momento da "historiografia brasileira moderna". Mais especificamente, gostaria de focar no uso que Iglésias faz de uma linguagem de vícios e virtudes para avaliar aqueles historiadores e seus trabalhos. Vícios e virtudes têm sido usados há muito não apenas para avaliações morais, mas também para avaliações epistêmicas. Ser reconhecido como historiador inclui cultivar repertórios de virtudes consideradas necessárias para ser, de fato, historiador. Enquanto Iglésias avalia seus predecessores, veremos como uma maneira particular de ser historiador - aquela do professor universitário dos anos de 1980 - confronta modelos anteriores de subjetividade acadêmica.
SOBRE EL COLAPSO DE LAS ESTRUCTURAS MATEMÁTICAS Y FÍSICAS EN EL REALISMO ESTRUCTURAL ÓNTICO
Authors: Soto Cristian
Published: August 2019

RESUMEN La sección 1 introduce lo que llamo la tesis del colapso de las estructuras matemáticas y las estructuras físicas. La sección 2 examina si acaso la indispensabilidad de las matemáticas para la física fundamental involucra la adopción del platonismo matemático, en este caso acerca de estructuras matemáticas, como argumenta el realismo estructural óntico. La sección 3 muestra que la adopción de la tesis del colapso arriesga introducir la hipótesis del universo matemático. Desde la perspectiva de la concepción inferencial en filosofía de las matemáticas aplicadas, la sección 4 examina aspectos epistémicos del rol de las matemáticas en la teorización científica, derivando distinciones entre estructuras matemáticas y estructuras físicas. El argumento concluye en la sección 5 indicando algunos límites para la presente estrategia.
UT PICTURA POESIS, WINCKELMANN E A ALEGORIA
Authors: Galé Pedro Fernandes
Published: August 2019

RESUMO O ensaio busca apresentar como as caracterizações da alegoria, em Winckelmann, ultrapassam a mera tentativa de se compreender um modo de figurar, nos moldes de uma iconologia, configurando uma espécie de metodologia geral para a compreensão da História da arte dos antigos e para a própria apreensão do ideal das artes. Tal possibilidade é dada num ambiente de debates artísticos que antecede a distinção canônico-romântica entre símbolo e alegoria.
MEMORY COMPATIBILISM: PRESERVING AND GENERATING POSITIVE EPISTEMIC STATUS
Authors: Rodrigues Tiegue Vieira
Published: August 2019

ABSTRACT The contemporary epistemological debate regarding the epistemic role of memory is dominated by the dispute between two different views: memory preservationism and memory generativism. While the former holds that memory only preserves the epistemic status already acquired through another source, the latter advocates that there are situations where memory can function as a generative epistemic source. Both views are problematic and have to deal with important objections. In this paper, I suggest a novel argument for granting memory the status of a generative source of justification and knowledge that overcomes objections raised for both preservationism and generativism. I shall call this view Memory Compatibilism. I argue that the proposed view better explains the generative epistemic character of memory.
Character strengths in the Brazilian northeast region: Contributions of personality beyond age and sex
Authors: COUTO Ricardo Neves , FONSÊCA Patrícia Nunes da
Published: August 2019

Abstract The objective was to verify to what extent the personality traits explain character strengths, controlling the effect of age and sex. A total of 251 individuals living in the Northeast region of Brazil (Mage = 18.51, SD = 9.03), 66.9% of which were women, answered a booklet containing the Character Strengths Scale, Five Major Factors Inventory (Big Five) and demographic issues. From the correlations, followed by multiple hierarchical regressions, it was found that age and sex were important to explain some strengths. Controlling the effect of these demographic variables, it was observed that the kindness, conscientiousness, extroversion and openness to experience personality traits directly explained these strengths, unlike the neuroticism trait, which did it inversely. Backed by the empirical evidence, it can be concluded that character strengths can be explained by personality traits and demographic variables (sex and age), collaborating with the expansion of knowledge in the area and understanding the positive aspects of the human being.
Schooling of Students with Intellectual Disabilities: Family and School Perspectives
Authors: Maturana Ana Paula Pacheco Moraes , Mendes Enicéia Gonçalves , Capellini Vera Lúcia Messias Fialho
Published: August 2019

Abstract Educational policies aimed at school inclusion have led to an increased enrollment of students with special education needs (SEN) in mainstream schools and, as a result, there is an increase in transfers from specialized institutions to mainstream schools. This study analyzed the perspectives of school professionals and family members on school transfers of students with intellectual disabilities (ID). Six family members and ten school professionals participated in the study. All attended semi-structured interviews, whose analysis allowed us to identify five thematic axes: teacher training; lack of preparation and information; lack of supports; lack of preparation for transfer; expectations regarding the ID student, mainly concerning behavioral characteristics, learning and performance. Results confirm data from research on the implementation of special education in inclusive environments, indicating that teachers’, managers’ and families’ conceptions of inclusion depend on the severity of the student’s disability, and on the skills and attitudes of the professionals.
La nature urbaine: dégradation quantitative et qualitative des espaces verts urbains, cas de la ville steppique de M’Sila, Algérie
Authors: Mili Mohamed , Boutabba Hynda , Boutabba Samir-Djemoui
Published: August 2019

Resume Le rôle de la nature dans une ville qui commence à prendre de l’ampleur en matière d’extension urbaine au dépens de ces espaces verts reste un sujet très peu développé dans les multiples études urbaines réalisées sur la ville de M’sila. En effet le centre de cette agglomération, dense de ses multiples lotissements et cités collectives d’habitat social, est toujours présenté comme un milieu hostile à la nature. Pourtant cette ville a été pendant longtemps un des greniers de blé et d’abricotiers de toute la région steppique du Hodna.En utilisant une approche historique et la technique de l’entretien “non-directif” qui favorise un déplacement du questionnement tourné vers le savoir et les expériences propres des acteurs publics sociaux ce papier tente de montrer la situation actuelle de la nature dans une ville algérienne caractérisée par un climat semi-aride ainsi que la manière de sa gestion par les différents acteurs de la ville.

Published: August 2019

Abstract: The objective of this work was to evaluate the effects of fertilization with nitrogen topdressing and silicates, as well as of the use of fungicides, on the occurrence of rice blast on panicles, milling yield, and whole grains, vitreous grains, and chalky kernels in a flood-irrigated rice cultivar sensitive to the disease. Two experiments were conducted in a randomized complete block design, in a 4×4×2 factorial arrangement, with four replicates: in experiment 1, four doses of nitrogen × four doses of calcium and magnesium silicate on soil × with and without fungicides; and, in experiment 2, four doses of nitrogen × four doses of potassium silicate applied on leaves x with and without fungicides. At the doses above 60 kg ha-1 nitrogen without fungicides, there was an increase of rice blast severity on panicles, a decrease in the percentage of whole and vitreous grains, and an increase in chalky kernels and chalky area. The greatest effects of silicates occurred without fungicides. Fungicide use reduced the severity of rice blast on panicles. Milling yield ranged from 60 to 70% in both experiments. The control of rice blast with fungicides maintains high rice grain quality, milling yield, and percentages of whole and vitreous grains.

Published: August 2019

Abstract: The objective of this work was to determine the nitrogen rate for fertigation associated with the maximum productivity of green corn (Zea mays) with a lower production cost, in two harvest seasons in the Brazilian semiarid region. The experimental design was a randomized complete block with four replicates, and the treatments consisted of four N rates (0, 80, 160, and 240 kg ha-1) in form of urea, applied via drip irrigation. The used cultivar was the Bt Feroz hybrid. The evaluated characteristics were: number and mass of marketable ears, gross income, net income, and rate of return. The greatest amounts of marketable ears were reached with 152.52 kg ha-1 N in summer (41,183.84 ears per hectare) and 190.31 kg ha-1 N in winter (53,291.25 ears per hectare). In the two harvests, there was a variation in production costs between R$ 2,422.12 ha-1 and R$ 3,320.95 ha-1 without N and with 240 kg ha-1 N, respectively. The winter harvest showed higher productivity and profitability of green ears with fertigation with 160 kg ha-1 N. In the Brazilian semiarid, the maximum productivity of green corn with the lowest production cost is reached with fertigation with 90 kg ha-1 N, in both harvests.

Published: August 2019

Abstract: The objective of this work was to evaluate the growth, relative chlorophyll index and nitrogen concentrations in leaves, and the grain yield of arabica coffee (Coffea arabica) fertilized with rates of N as coated and conventional urea, in a sandy soil under rainfed conditions. The experiment was carried out over three crop years, using 'Mundo Novo IAC 388-17-1' coffee, in a randomized complete block design, in a 3×2+1 factorial arrangement, with three treatments with 150, 300, and 600 kg ha-1 N, as coated and conventional urea, and a control without N, with six replicates. Nitrogen increased stem diameter, plant height, N concentrations and relative chlorophyll index in the leaves, as well as grain yield. Over the three crop years, the highest N rate provided the greatest grain yield. Coated urea has no advantage over the conventional one, in supplying N to arabica coffee crop, in sandy soil under rainfed conditions.
Carácter monocultural de la evaluación diagnóstica de necesidades educativas especiales en contexto mapuche
Authors: Gutiérrez-Saldivia Ximena , Millán Segundo Quintriqueo , Zambrano Vanessa Valdebenito
Published: August 2019

Resumen El objetivo de este trabajo es analizar críticamente las prácticas de evaluación diagnóstica de Necesidades Educativas Especiales (NEE) en contexto mapuche. Desde esta perspectiva, se sostiene que los procesos de evaluación diagnóstica de NEE que se les realizan a estudiantes mapuches constituyen una práctica pedagógica monocultural. A partir del punto de vista metodológico, se realiza una revisión bibliográfica de investigaciones empíricas y teóricas sobre la evaluación de NEE en contextos de diversidad social y cultural. Para ello se realiza una búsqueda de artículos científicos en las bases de datos Web of Science, Scielo y Eric. Los resultados develan que la política educativa chilena impone un modelo de evaluación diagnóstica de NEE estandarizado, por tanto es aplicado de una misma forma en todos los centros educativos de las distintas regiones del país, sin distinción, convirtiéndose en un dispositivo legal que responde a aspectos teóricos-prácticos, pero no a la diversidad social y cultural presente en el territorio. La evaluación diagnóstica de NEE adopta un carácter monocultural, ya que se basa en la clasificación internacional del funcionamiento de la discapacidad y de salud, y en pruebas estandarizadas para la población chilena no indígena. Se concluye que el diagnóstico de NEE de estudiantes mapuches es consecuencia de la distancia epistemológica entre el conocimiento mapuche y conocimiento escolar-occidental en muchos casos, y no necesariamente a dificultades de aprendizaje y participación a causa de una discapacidad o trastorno.
ACE: An Actor Ensemble Algorithm for Continuous Control with Tree Search
Authors: Zhang Shangtong , Yao Hengshuai
Published: August 2019

In this paper, we propose an actor ensemble algorithm, named ACE, for continuous control with a deterministic policy in reinforcement learning. In ACE, we use actor ensemble (i.e., multiple actors) to search the global maxima of the critic. Besides the ensemble perspective, we also formulate ACE in the option framework by extending the option-critic architecture with deterministic intra-option policies, revealing a relationship between ensemble and options. Furthermore, we perform a look-ahead tree search with those actors and a learned value prediction model, resulting in a refined value estimation. We demonstrate a significant performance boost of ACE over DDPG and its variants in challenging physical robot simulators.
