How a change in Brazil's sugar policies would affect the world sugar market
No full textAlthough Brazil is the world's largest sugarcane producer, only one-third of the cane it grows is used to produce sugar; the rest is used to produce ethanol as fuel for automobiles. Still, Brazil is the world's fourth largest sugar producer. This paper asks what it would mean for Brazil and for the world sugar market if Brazil were to shift largely away from ethanol to sugar production. This question is of keen interest for the world sugar market because such a shift -- although politically difficult -- is possible. Brazil's system of controlling the sugarcane and sugar industries to ensure enough ethanol for domestic fuel needs is costly. The author concludes that although Brazil could influence world sugar prices significantly in the short run, it could not influence them to its short- or long-term advantage by restricting production. Indeed, to the extent that Brazil could make world prices more stable by allowing its producers increased flexibility in production, removing existing production controls could provide not only substantial economic gains (in terms of increased exports to Brazil), but also more stable world prices. For other producers, there could be a tradeoff in terms of lower but more stable income.Environmental Economics&Policies,Economic Theory&Research,Access to Markets,Markets and Market Access,Consumption

LOS TRAYECTOS ACADEMICOS DE ESTUDIANTES UNIVERSITARIOS Y SU RELACIÓN CON CONDICIONES SOCIODEMOGRÁFICAS
No full textLos objetivos del proyecto cuyos avances se presentan en este trabajo son: a) construir distintos perfiles de ingreso a las carreras de la Facultad de Ciencia Política y RR.II., según características sociodemográficas, experiencias previas de aprendizaje y recursos disponibles. b) vincular rasgos sociodemográficos de los estudiantes con rendimiento académico, a través del seguimiento de las cohortes de ingreso, para analizar posibles cambios en dichas características y potenciales razones que intervienen en el rendimiento o posible abandono. Estos resultados corresponden al seguimiento de la cohorte 2004, definida por el indicador “al menos 1 materia rendida”, independientemente del resultado obtenido. El tránsito de los estudiantes por los diferentes momentos de la carrera se analiza a través del número de materias aprobadas; lo que permite marcar los diferentes ritmos en la caída constante en la proporción de alumnos que avanzan a lo largo de los años de la carrera. El ritmo de decrecimiento es más pronunciado en los tramos iniciales y finales de las carreras. Esto tiene implicancias diferentes para el análisis de la cohorte ya que la caída más cercana al comienzo tendría más probabilidad de marcar abandono mientras que hacia el final, mostraría rezago en el ritmo de avance en la carrera
Orientacions pedagògiques del pintor Fèlix Mestres i Borrell (1873-1933): l’ensenyament primari
No full textLa faceta de teòric esdevé un dels aspectes més desatesos del pintor Fèlix Mestres i Borrell (Barcelona, 1873-1933). En el present article ens concentrem en el pensament pedagògic de l’artista, amb l’objectiu d’emmarcar-lo en el context històric educatiu català i internacional de començament del segle xx. La font principal d’estudi és el text de la conferència Orientaciones sobre la enseñanza del dibujo (1916), en el qual Fèlix Mestres disserta sobre l’educació artística a l’escola primària i es posiciona, clarament, a favor dels corrents reformadors.Paraules clau: Fèlix Mestres Borrell, història de l’educació artística, ensenyament del dibuix.The art theory essays by Catalan painter Fèlix Mestres Borrell (Barcelona, 1873- 1933) are one of his less closely studied facets. This article explores the artist’s pedagogical thinking in its historical context. Our main source is the text of the conference Orientaciones sobre la enseñanza del dibujo (1916), where Fèlix Mestres analyzes art-education in primary schools and he makes clear his position in favour of reformist currents of opinion.Key words: Fèlix Mestres Borrell, History of Art Education, Teaching Drawing.La faceta de teórico conforma uno de los aspectos menos estudiados del pintor Fèlix Mestres y Borrell (Barcelona, 1873-1933).

125è aniversari del naixement de l'escultor i acadèmic Borrell i Nicolau
No full text[ca] En el 125è aniversari del naixement de l'escultor Borrell i Nicolau, l'estudi per a l'obra de l'escultor s'uneix a una reivindicació de l'artista. En primer lloc, per elogiar-ne la qualitat: la seva obra conforma una col·lecció d'escultures de primer nivell. Són figures delicades i harmòniques que no han perdut, malgrat tot, l'energia de l'escultura. Aspectes que Borrell i Nicolau va aprendre al llarg de la seva carrera i que ens indica la seva modernitat, la innovació sense un canvi de llenguatge, mantenint-se en el món clàssic de la figura . Un artista poc estudiat i escassament representat a les diverses exposicions del període, i que n. No obstant això va formar part activa del moviment cultural i artístic desenvolupat en el seu context vital. Borrell i Nicolau aconseguí deixar enrere les premisses de l'escultura del XIX, en les quals s'havia format, i avançar, amb llenguatge propi, tot integrant aspectes del Noucentisme i del Nou Classicisme francès, amb un interès creixent cap al naturalisme, tot creant un estil personal, clàssic i modern.

[en] Celebrating the 125th anniversary of the birth of the sculptor Borrell i Nicolau, the article presents a study of his works and a vindication of the artist. He is a little-studied artist who is poorly represented in the exhibitions of the period, but he took an active role in the cultural and artistic movement developed within the context of his life. Borrell i Nicolau managed to leave behind the premises of the sculpture of the 19th century, in which he was formed, and advanced, with his own language, integrating aspects of Catalan Noucentisme and French New Classicism, with a growing interest in naturalism creating a classic and modern personal style

A Multi-Language Comparison of Influences on Author Verification using Character N-Grams
No full textWe create a new multi-language corpus for author verification based on Wikipedia talkpages, and evaluate the influence that differences in topic and time have on character n-gram author profiles. Topic alignment between two texts is found to increase author verification precision, and an authors writing style is found to change over time, but not more significantly after 3 years than after 1 year.Information ArchitectureWISElectrical Engineering, Mathematics and Computer Scienc
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
The vanishing author in computer-generated works: a critical analysis of recent Australian case law
No full textAbstract
The use of software is ubiquitous in the creation of many copyright works, yet the requirement in copyright law that every work have a human author who engages in independent intellectual effort means that its use may prevent copyright subsistence. Several recent Australian cases have refocused attention on authorship as an essential criterion of copyright subsistence, and these cases suggest that much computer-produced output may be authorless and thus lack copyright protection. This article, the first in a two-part series, analyses how each case deals with the question of authorship of computer-produced works and why the use of software diminishes copyright protection for a significant number of computer-generated works. The article critiques the application of conventional notions of human authorship developed in the pre-computer age to modern productions and suggests alternative approaches to authorship that satisfy both the major objectives of copyright policy and the need to adapt to the computer age. The article argues that, without a broader judicial approach to authorship of computer-generated works, Parliament must remedy the lacuna in protection for these ‘authorless’ works. Possible solutions for reform are suggested. In a forthcoming article, the author comprehensively examines those reform proposals
