Subjetividades políticas desde la representación : fotografía documental del campesinado en Colombia (1965-1975)

Esta investigación explora arqueológicamente el saber constituido sobre el campesinado en Colombia, en el período de 1965-1975, tomando como material empírico principal un archivo fotográfico documental que relacionaremos con hemerografía y las reconstrucciones socio-históricas de la década. Nuestro propósito es relacionar el archivo, sus condiciones, su porvenir, medios y definiciones con la constitución de subjetividades políticas. Las subjetividades son entendidas aquí en tanto procesos que al referir universos simbólicos socialmente compartidos, dotan al sujeto de un lenguaje cultural que a continuación internaliza, y adquiere así una singularidad que lo caracteriza y finalmente lo representa como “ser colectivo”. Descifraremos, a través de lo visible y lo oculto de las representaciones fotográficas, los enunciados posibles y las aproximaciones desde la sociología. Veremos como los discursos, por demás contradictorios, fungen a manera de proyectos de homogeneización de la cultura campesina efectuándose en la esfera de la heterogeneidad: campesinos marcados por diferencias entre sí, multiplicidad de subjetividades implicadas políticamente en los procesos inscritos dentro de la reforma agraria.

A importância e a influência do génio de Frédéric Chopin (1810-1849) na vida e obra do pianista e compositor Milosz Magin (1929-1999)

Este Trabalho de Projecto é composto por duas partes: uma de índole teórica e outra de índole prática. No que diz respeito a parte teórica, ela compõe-se por uma exposição que se divide em quatro capítulos. O primeiro capítulo toma como ponto de partida a apresentação da vida de Milosz Magin, um pianista e compositor europeu da segunda metade do século XX. Os objectivos do segundo capítulo são os de salientar e explicar a influência que Frédéric Chopin teve na vida de Milosz Magin. Este capítulo centra-se nos paralelismos biográficos entre ambos, essencialmente, naqueles que dizem respeito às suas vidas enquanto pianistas e compositores. O terceiro capítulo inclui o estudo analítico e comparativo das semelhanças entre a Sonata em sí bemol menor op. 35 de Frédéric Chopin e a Sonata n.º 1 de Milosz Magin. O quarto capítulo analisa a Mazurka em fá menor op. póstuma de Frédéric Chopin, a qual foi, completamente, reconstruída por Milosz Magin. Ela constitui mais um exemplo paradigmático da influência e importância de Frédéric Chopin na obra do compositor. ABSTRACT: This Project consists of two parts: one of a theoretical nature and the other of a practical one. The theoretical part is in itself made up of an exposition divided into four parts. The first chapter deals with the presentation of Milosz Magin's life, European pianist and composer from the second half of the 20th Century. The objective of the second chapter is to emphasize and explain the influence that Frédéric Chopin had on the life of Milosz Magin. It will concentrate on the biographical parallelisms between Frédéric Chopin and Milosz Magin, essentially on those that concern their lives as pianists and composers. The third chapter includes an analytical and comparative study of the similarities between the Sonata in B Flat minor Op. 35 by Frédéric Chopin and the Sonata n° 1 by Milosz Magin. The fourth chapter analyzes the Mazurka in F minor op. posthume by Frédéric Chopin, completely reconstructed by Milosz Magin, which in itself establishes one more example of the influence and importance Frédéric Chopin had on the works of Milosz Magin.

"Nos llaman ladrones y se roban nuestro salario": Hacia una reinterpretación de la movilización rural salvadoreña, 1929-1931.

ResumenEste artículo examina los orígenes sociales de los movimientos que desencadenaron la revuelta campesina de 1932 en el centro-occidente de El Salvador. Utiliza fuentes orales y documentales nuevas, para trazar la forma en que el reformismo, la crisis económica y el activismo de los militantes comunistas lograron romper las barreras étnicas y regionales que dividían al campesinado occidental y estimular una movilización masiva.AbstractThis article delves into the social origins of the movements that triggered the 1932 peasant revolt in the central-western region of El Salvador. The authors used new oral and documentary sources to outline the way in which reformism, the economic crisis, and the communist activism managed to break the ethnic and regional barriers that divided the western peasantry and fostered a massive mobilization.

El autor analiza los grupos consumidores de droga, y presenta un retrato del mundo de los trabajadores josefinos. También rescata algunos rasgos de los aparatos estatales que aplicaron medidas para la supresión del escándalo y aporta elementos para conocer cómo se expresaba la conciencia de clase fuera de las organizaciones obreras.

INFLUÊNCIAS DO SISTEMA CUBANO DE PRODUÇÃO DE CANA-DE-AÇÚCAR SOBRE AS USINAS DE SÃO PAULO (BRASIL): 1875-1929

La producción de azúcar ha jugado un papel central en gran parte de la historia de Cuba, así como en Brasil. En algunos períodos de la historia de estos dos países se consideró esta actividad, tecnológicamente hablando, moderna, y en otros se mostraron retrasos y demoras.Durante el período que cubrimos, 1875-1929, el cultivo de caña de azúcar de Cuba fue el más desarrollado del mundo, presentando altos niveles de productividad. Ya la de Brasil estaba estancada en el tiempo, totalmente incapaz de competir en el mercado internacional.En Brasil, el estado de Sao Paulo se perfilaba como un productor emergente, dotado de una mayor capacidad de asimilación de la tecnología y la expansión del cultivo de caña de azúcar. En el proceso de despliegue de sus modernas plantas en primer lugar, el ejemplo de Cuba fue de grande influencia a los productores de Sao Paulo.Lo que pretendemos analizar con esta investigación es cómo el sistema cubano de transporte de la caña tuvo divulgación y fue asimilado parcialmente en el estado de Sao Paulo, que pronto se convertiría en el principal productor de azúcar en el Brasil. 

Islet Neogenesis-associated Protein (ingap): The Role Of Its Endogenous Production As A Positive Modulator Of Insulin Secretion.

Islet neogenesis-associated protein (INGAP) is a peptide found in pancreatic exocrine-, duct- and islet- non-β-cells from normal hamsters. Its increase induced by either its exogenous administration or by the overexpression of its gene enhances β-cell secretory function and increases β-cell mass by a combination of stimulation of cell replication and islet neogenesis and reduction of β-cell apoptosis. We studied the potential modulatory role of endogenous INGAP in insulin secretion using two different experimental approaches. Hamster islets transfected with INGAP-small interfering RNA (INGAP-siRNA) were used to study glucose-stimulated insulin secretion (GSIS). In parallel, freshly isolated islets were incubated with high glucose and the same concentration of either a specific anti-INGAP rabbit serum or normal rabbit serum. INGAP-siRNA transfected islets reduced their INGAP mRNA and protein content by 35.1% and 47.2%, respectively whereas GSIS decreased by 25.8%. GSIS by transfected islets attained levels comparable to those recorded in control islets when INGAP pentadecapeptide (INGAP-PP) was added to the culture medium. INGAP antibody in the medium decreased significantly GSIS in a dose-dependent manner. These results indicate that endogenous INGAP plays a physiological positive modulatory role in insulin secretion, supporting its possible use in the treatment of prediabetes and Type 2 diabetes.

Review of the Brazilian Atlantic Rainforest harvestman Longiperna (Opiliones: Gonyleptidae: Mitobatinae)

Longiperna Roewer, 1929 is revised and new records of distribution are presented for the Brazilian Costal Atlantic Rain Forest (from Rio de Janeiro to Santa Catarina states). The following new synonymies are established: Longiperna concolor (Mello-Leitão, 1923) = L. zonata Mello-Leitão, 1935 and L. heliaca B. Soares, 1942; Longiperna coxalis (Roewer, 1943) = L. areolata B. Soares, 1944; Longiperna insperata (Soares & Soares, 1947) = L. paranensis Soares & Soares, 1947 and L. curitibana Kury, 2003. Two new species are described: Longiperna kuryi sp. nov. (type-locality: Brazil, Rio de Janeiro, Parati); Longiperna trembao sp. nov. (type-locality: Brazil, Minas Gerais, Belo Horizonte).

Systematic review and cladistic analysis of the genus Eusarcus Perty 1833 (Arachnida, Opiliones, Gonyleptidae)

Eusarcus Perty 1833 is one of the oldest described genera of Pachylinae, comprising 36 species distributed from northeastern to southern Brazil (including the central west region), northeastern Argentina, eastern Paraguay and Uruguay. The genus is reviewed and a new classification is proposed based on a cladistic analysis. A cladistic analysis was performed with the 34 valid species of Eusarcus and 11 species belonging to certain Gonyleptidae subfamilies. The data matrix has 67 characters: 14 from dorsal scutum and pedipalp, 38 from male legs and 15 from male genitalia. Two equally parsimonious trees were found (L=319; C. I.=0.26, R. I.=0.61). Pygophalangodus gemignanii uruguayensis Ringuelet 1955a and Pygophalangodus gemignanii gemignanii Mello-Leitao 1931b are here elevated to the category of species, and the following new combinations are proposed: E. catharinensis (Mello-Leitao 1927); E. berlae (Mello-Leitao 1932); E. gemignanii (Mello-Leitao 1931b); E. signatus(Roewer 1949); E. sooretamae (Soares & Soares 1946a); E. uruguayensis (Ringuelet 1955a). The following generic synonymies are proposed: Eusarcus Perty 1833 (type species E. armatus Perty 1833) = Metagraphinotus Mello-Leitao 1927 (type species M. catharinensis Mello-Leitao 1927), Pareusarcus Roewer 1929 (type species P. corniculatus Roewer 1929), Pygophalangodus Mello-Leitao 1931b (type species P. gemignanii-gemignanii Mello-Leitao 1931b) and Antetriceras Roewer 1949 (type species A. signatus Roewer 1949). The following specific synonymies are proposed: Eusarcus hastatus Sorensen 1884 = Pucrolioides argentina Roewer 1913, E. guimaraensi H. Soares 1945, Jacarepaguana pectinifemur Piza 1943, Canestrinia canalsi Mello-Leitao 1931a, and E. maquinensis H. Soares 1966b; E. armatus Perty 1833 = E. curvispinosus Mello-Leitao 1923b, and Enantiocentron montis Mello-Leitao 1936; Eusarcus catharinensis (Mello-Leitao 1927) = E. antoninae Mello-Leitao 1936, E. perpusillus Mello-Leitao 1945, E. tripos Mello-Leitao 1940, and Metagraphinotus trochanterspinosus Soares & Soares 1947b; E. nigrimaculatus Mello-Leitao 1924 = Pareusarcus centromelos Mello-Leitao 1935a, E. furcatus Roewer 1929, Orguesia armata Roewer 1913, and Pareusarcus corniculatus Roewer 1929; E. oxyacanthus Kollar in Koch 1839a = Enantiocentron doriphorus Mello-Leitao 1932, and E. spinimanu Mello-Leitao 1932; E. pusillus Sorensen 1884 = E. vervloeti B. Soares 1944c; E. berlae Mello-Leitao 1932 = Metagraphinotus arlei Mello-Leitao 1935a. Metapucrolia armata (Sorensen 1895) is revalidated, transferred to Eusarcus and considered as a species inquirenda. A new name, Eusarcus metapucrolia is proposed for this species to avoid homonymy with the type species of Eusarcus, E. armatus Perty 1833. Eusarcus aberrans Mello-Leitao 1939a is considered as a species inquirenda. The male of E. teresincola Soares & Soares 1946a is described. Female of the following species are described: E. bifidus Roewer 1929; E. dubius B. Soares 1943b; E. insperatus B. Soares 1944a; E. schubarti Soares & Soares 1946a; E. sooretamae (Soares & Soares 1946a). The following new species are described from Brazil: E. acrophthalmus (type locality: Bahia, Ilheus, Parataquice); E. alpinus (Rio de Janeiro, Santa Maria Madalena, Parque Estadual do Desengano); E. caparaoensis (Minas Gerais, Alto Caparao, Parque Nacional do Caparao); E. cavernicola (Goias, Sao Domingos, Parque Estadual de Terra Ronca, Lapa da Angelica); E. didactylus (Rio de Janeiro, Teresopolis, Parque Nacional Serra dos Orgaos); E. garibaldiae (Santa Catarina, Itajai); E. geometricus (Rio de Janeiro, Teresopolis, Parque Nacional Serra dos Orgaos); E. manero (Rio de Janeiro, Marica, Itaipuacu); E. matogrossensis (Mato Grosso, Chapada dos Guimaraes); E. mirabilis (Minas Gerais, Marlieria, Parque Estadual Rio Doce); E. sergipanus (Sergipe, Itabaiana, Parque Nacional de Itabaiana) and E. tripectinatus (Minas Gerais, Rio Preto). The holotype of E. curvispinosus is proposed as the neotype of E. armatus Perty 1833, the type material of which has been lost. Lectotypes for the following species were designated: E. aduncus; E. hastatus; E. oxyacanthus.

Effect of alpha prime due to 475 degrees C aging on fracture behavior and corrosion resistance of DIN 1.4575 and MA 956 high performance ferritic stainless steels

The 475 degrees C embrittlement in stainless steels is a well-known phenomenon associated to alpha prime (alpha`) formed by precipitation or spinodal decomposition. Many doubts still remain on the mechanism of alpha` formation and its consequence on deformation and fracture mechanisms and corrosion resistance. In this investigation, the fracture behavior and corrosion resistance of two high performance ferritic stainless steels were investigated: a superferritic DIN 1.4575 and MA 956 superalloy were evaluated. Samples of both stainless steels (SS) were aged at 475 degrees C for periods varying from 1 to 1,080 h. Their fracture surfaces were observed using scanning electron microscopy (SEM) and the cleavage planes were determined by electron backscattering diffraction (EBSD). Some samples were tested for corrosion resistance using electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization. Brittle and ductile fractures were observed in both ferritic stainless steels after aging at 475 degrees C. For aging periods longer than 500 h, the ductile fracture regions completely disappeared. The cleavage plane in the DIN 1.4575 samples aged at 475 degrees C for 1,080 h was mainly {110}, however the {102}, {314}, and {131} families of planes were also detected. The pitting corrosion resistance decreased with aging at 475 degrees C. The effect of alpha prime on the corrosion resistance was more significant in the DIN 1.4575 SS comparatively to the Incoloy MA 956.

Communism and Public Opinion in Queensland, 1939-1951 : An Explanation of Queensland's Vote in the 1951 Anti-Communist Referendum

The starting point of this thesis was a desire to explain the rapid demise in the popularity which the Communist Party enjoyed in Queensland during the second world war. Wartime Queensland gave the Australian Communist Party its highest state vote and six years later Queensland again gave the Communist Party its highest state vote - this time however, to ban the Party. From this I was led into exploring the changing policies, beliefs and strategies of the Party, as well as the many sub-groups on its periphery, and the shifts in public response to these. In 1939 Townsville elected Australia's first Communist alderman. Five years later, Bowen elected not only Australia's first but also the British Empire's first, Communist state government member. Of the five electorates the Australian Communist Party contested in the 1944 Queensland State elections, in none did the Party's candidate receive less than twenty per-cent of the formal vote. Not only was the Party seemingly enjoying considerable popular support but this was occurring in a State which, but for the Depression years (May 1929 - June 1932) had elected a Labor State Government at every state election since 1915. In the September 1951 Constitution Alteration Referendum, 'Powers To Deal With Communists and Communism', Queensland regist¬ered the nation's highest "Yes" majority - 55.76% of the valid vote. Only two other states registered a majority in favour of the referendum's proposals, Western Australia and Tasmania. As this research was undertaken it became evident that while various trends exhibited at the time, anti-Communism, the work of the Industrial Groups, Labor opportunism, local area feelings, ideological shifts of the Party, tactics of Communist-led unions, etc., were present throughout the entire period, they were best seen when divided into three chronological phases of the Party's history and popularity. The first period covers the consolidation of the Party's post-Depression popularity during the war years as it benefited from the Soviet Union's colossal contribution to the Allied war efforts, and this support continued for some six months or so after the war. Throughout the period Communist strength within the trade union movement greatly increased as did total Party membership. The second period was marked by a rapid series of events starting in March 1946, with Winston Churchill's "Official Opening" of the Cold War by his sweeping attack on Communism and Russia, at Fulton. Several days later the first of a series of long and bitter strikes in Communist-led unions occurred, as the Party mobil¬ized for what it believed would be a series of attacks on the working class from a ruling class, defending a capitalist system on the verge of an economic collapse. It was a period when the Party believed this ruling class was using Labor reformism as a last desperate 'carrot' to get workers to accept their lot within a capitalist economic framework. Out of the Meat Strike emerged the Industrial Groups, who waged not only a determined war against Communist trade union leadership but also encouraged the A.W.U.-influenced State Labor apparatus to even greater anti-Communist antagonisms. The Communist Party's increasing militancy and Labor's resistance to it, ended finally in the collapse of the Chifley Labor government. Characteristically the third period opens with the Communist Party making an another about-face, desperately trying to form an alliance with the Labor Party and curbing its former adventurist industrial policy, as it prepared for Menzies' direct assault. The Communist Party's activities were greatly reduced, a function of both a declining member-ship and, furthermore, a membership reluctant to confront an increasingly hostile society. In examining the changing policies, beliefs and strategies of the Party and the shifts in public response to these, I have tried to distinguish between general trends occurring within Australia and the national party, and trends peculiar to Queensland and the Queensland branch of the Party, The Communist Party suffered a decline in support and membership right across Australia throughout this period as a result of the national policies of the Party, and the changing nature of world politics. There were particular features of this decline that were peculiar to Queensland. I have, however, singled out three features of particular importance throughout the period for a short but more specifically detailed analysis, than would be possible in a purely chronological study: i.e. the Party's structure, the Party's ideological subservience to Moscow, and the general effect upon it of the Cold War.

A review of the Apocreadiidae Skrjabin, 1942 (Trematoda : Digenea) and description of Australian species

The Apocreadiidae is reviewed and is considered to include genera recognised previously within the families Apocreadiidae, Homalometridae, Schistorchiidae, Sphincterostomatidae and Trematobrienidae. Key features of the family are extensive vitelline follicles, eye-spot pigment dispersed in forebody, I-shaped excretory vesicle, no cirrus-sac and genital pore opening immediately anterior to the ventral sucker (usually) or immediately posterior to it (Postporus Manter, 1949). Three subfamilies and 18 genera are recognised within the Apocreadiidae. The Apocreadiinae comprises Homalometron Stafford, 1904 (new syn. Barbulostomum Ramsey, 1965), Callohelmis n. g., Choanodera Manter, 1940, Crassicutis Manter, 1936, Dactylotrema Bravo-Hollis & Manter, 1957, Marsupioacetabulum Yamaguti, 1952, Microcreadium Simer, 1929, Myzotus Manter, 1940, Neoapocreadium Siddiqi & Cable, 1960, Neomegasolena Siddiqi & Cable, 1960, Pancreadium Manter, 1954, Procaudotestis Szidat, 1954 and Trematobrien Dollfus, 1950. The Schistorchiinae comprises Schistorchis Luhe, 1906, Sphincterostoma Yamaguti, 1937, Sphincteristomum Oshmarin, Mamaev & Parukhin, 1961 and Megacreadium Nagaty, 1956. The Postporinae comprises only Postporus. A key to subfamilies and genera of the Apocreadiidae is provided. It is argued that there is no convincing basis for the recognition of the genus Apocreadium Manter, 1937 and all its constituent species are combined with Homalometron. The following new combinations are proposed for species previously recognised within Apocreadium: Homalometron balistis (Manter, 1947), H. caballeroi (Bravo-Hollis, 1953), H. cryptum (Overstreet, 1969), H. longisinosum (Manter, 1937), H. manteri (Overstreet, 1970), H. mexicanum (Manter, 1937) and H. vinodae (Ahmad, 1985). Apocreadium uroproctoferum Sogandares-Bernal, 1959 is found to lack a uroproct and is made a synonym of H. mexicanum. Homalometron verrunculi nom. nov. is proposed to replace the secondarily pre-occupied H. caballeroi Lamothe-Argumedo, 1965. Barbulostomum is made a synonym of Homalometron and H. cupuloris (Ramsey, 1965) n. comb. is proposed. Neochoanodera is made a synonym of Choanodera and Choanodera ghanensis (Fischthal & Thomas, 1970) n. comb. is proposed. Species within the Apocreadiinae and Postporinae are reviewed and the following are recorded or described from Australian fishes: Homalometron wrightae n. sp. from Achlyopa nigra (Macleay), H. synagris (Yamaguti, 1953) n. comb. from Scolopsis monogramma (Cuvier), H. stradbrokensis n. sp. from Gerres subfasciatus Cuvier, Marsupioacetabulum opallioderma n. sp. from G. subfasciatus, Neoapocreadium karwarensis (Hafeezullah, 1970) n. comb. from G. subfasciatus, N. splendens n. sp. from S. monogramma and Callohelmis pichelinae n. g., n. sp. from Hemigymnus melapterus (Bloch), H. fasciatus (Bloch), Stethojulis bandanensis (Bleeker) andChoerodon venustus (De Vis). Callohelmis is recognised by the combination of absence of tegumental spines, caeca terminating midway between the testes and posterior end of body, ventral sucker enclosed in a tegumental pouch, prominent muscles radiating through the body from the ventral sucker, vitelline follicles not extending into the forebody, and a very short excretory vesicle that opens ventrally. New combinations for species previously recognised within Crassicutis are proposed as follows: Neoapocreadium caranxi (Bilqees, 1976) n. comb., N. gerridis (Nahhas & Cable, 1964) n. comb., N. imtiazi (Ahmad, 1984) n. comb. and N. marina (Manter, 1947) n. comb. The host-specificity and zoogeography of the Apocreadiinae are considered.
