Educação do Campo [Education for and by the countryside] as a political project in the context of the struggle for land in Brazil

Latin American and Brazilian rural social movements believe that significant social transformation requires the collective construction of a political project of an historical character. Education is conceived as an historical–cultural and political project to transform the peasantry into an historical subject through emancipatory educational–pedagogical praxis. The Landless Workers Movement (MST), the most emblematic peasant movement in Brazil, has played the leading role in this debate, which also includes many other peasant organizations. The MST has identified education as the key element in forging an historical–political actor out of the landless peasantry. This is articulated through the struggle for education for rural peoples, and along a theoretical–epistemic axis that revolves around the emergent concept of Educação do Campo (‘Education for and by the Countryside’). I ask how the MST conceptualizes education, and what the role is of education in strengthening peasant resistance and sharpening the dispute between political projects for the countryside. I focus on the epistemic dimensions of the concepts of education and pedagogy in the trajectory of the MST in Brazil, and I examine Educação do Campo as an educational-political project and in terms of policy conquests in the political dispute between the rival political projects for the Brazilian countryside of peasants and capital.     

Religiöse Diskurstraditionen

Die jüngere Forschung zum sozialen Handeln von Muslimen in westeuropäischen Einwanderungsländern hebt häufig die reflexive Individualisierung von Lebensformen und religiösen Gesinnungen vor allem junger Muslime hervor. Der folgende Beitrag hinterfragt die diesem Ansatz zugrunde liegende Annahme eines Wertekanons ziviler europäischer Gesellschaften und Öffentlichkeiten, in die sich in Europa sozialisierte junge Muslime vermeintlich einfügen und muslimische Identitäten ?europäisch“ rekonstruieren. Dieser Transformationsprozess wird in diesen Theorien sowohl im Hinblick auf die familiale Lebenswelt wie im Hinblick auf die öffentliche Sphäre, in denen Muslime agieren, unterschätzt. Im Rückgriff auf Ansätze der historisch-vergleichenden Soziologie und der Religionsanthropologie erarbeitet der Aufsatz zunächst einen Begriff von ?Tradition“, der die Konstituierung, Verwaltung und Transformation von religiösen Diskursen, Praxen und Subjekten diachronisch und transgenerationell erklärt und der Gleichzeitigkeit von sozialer Einbettung und diskursiver Autonomie von Tradition Rechnung trägt. Wir zeigen, dass die sozialen Praktiken von Muslimen in Europa eine Transformation erfahren, die ihre besondere Grundlage im muslimischen Reformdiskurs im kolonialen und postkolonialen Kontext mehrerer Zentren der islamischen Welt hat. Der Fall junger Kopftuch tragender Musliminnen in Deutschland und Frankreich, die der zweiten und dritten Migrantengeneration angehören, zeigt schließlich weder eine selbst-reflexive Identitätssuche noch das ?coming out“ der Heldinnen einer nicht-westlichen Modernität, sondern ein praxisorientiertes und wissensgestütztes Räsonieren der jungen Frauen über die Wiedereinbettung des Traditionsdiskurses in die sozialen Felder (Familie, Studium, Arbeit und islamische Vereine), in denen sie operieren. Ihr Streben, das von der Traditionsdynamik der Kohärenzsuche geleitet wird, konfiguriert eine ?Alltagspolitik“, in der die Frauen ihre islamisch inspirierten Lebensprojekte gleichzeitig von moralisch erstarrten familiären ?Lebenswelten“ und von normativ erstarrten politischen Öffentlichkeiten abkoppeln und kultivieren.     

Mitochondrial DNA error prophylaxis: assessing the causes of errors in the GEP'02-03 proficiency testing trial

A qualitative and quantitative analytical method was developed and validated for the determination of 49 licit and illicit drugs in oral fluid. Small oral fluid samples, volume 1mL, were collected from volunteers using a modified Omni-Sal device and the analytes were extracted from an oral fluid/buffer mixture using a single Bond Elut Certify solid phase extraction cartridge. Liquid chromatography-tandem mass spectrometry (LC-MS-MS) and gas chromatography-repetitive full scan mass spectrometry (GC-MS) were used in parallel to analyze the extracts for the targeted drugs. Extracts were analyzed by GC-MS in their underivatized form and as their pentafluoropropionyl derivatives. Deuterated internal standards were used for quantification of drugs of abuse by LC-MS-MS to minimize matrix effects. Methadone-d(9) and tumoxetine were used as the internal standards for quantification of non-derivatized and derivatized analytes respectively by GC-MS. Linearity was demonstrated over the range 5-200 ng/mL and limits of detection were less than 4 ng/mL for each drug analyzed. The method demonstrated acceptable recoveries for most of the analytes and good intra- and inter-day precision. Acquisition of data by repetitive full scan GC-MS allows the addition of further analytes to the target menu.     

Genetic analysis of fingerprints—Could WGA or nested-PCR be alternatives to the increase of PCR cycles number?

In this work we aimed to compare the application of increasing PCR cycle number, whole genome amplification and nested-PCR on fingerprints genetic analysis. Results were compared for correct alleles, allele dropin and allelic dropout. We concluded that increasing the number of PCR cycles is yet the best way to attain the required sensitivity.     

Y-SNPs analysis using two different approaches in a Northern Portugal male population sample

The non-recombining portion of the human Y (NRY) chromosome has various types of variation, including single nucleotide polymorphism (SNP). In spite of their low discrimination power, they provide a powerful and simple exclusion tool for forensic purposes. A special advantage of SNPs is that it can potentially detect smaller DNA fragments (analysis of degraded DNA).The aim of this work consisted in the analysis of a group of SNP polymorphisms (M2, M9, M35, M89, M45, M170, M172, M173, M207 and P25) in a Northern Portugal male population sample, which allows the determination of the most common European haplogroups, including the Northern Portugal ones.The method used for typing these polymorphisms was the real-time PCR with TaqMan probes on the ABI 7000 platform (Applied Biosystems).We had some difficulties in typing some of the markers using this approach. However, the preliminary results obtained for the defined haplogroups are in accordance with those described in close European populations. To confirm the typing and solve the doubts that emerged from the real-time approach, the samples were also typed using SNapShot.     

Genetic study of 15 STRs loci of Identifiler system in Angola population

Angola is located in the African continent, in the area of southern Africa and has a population of approximately 14 million inhabitants. The Angola population has origin from Occidental and Southern Bantu people that came from the great lakes region, creating the most ever known African migration of our days.Allele frequencies for the 15 STRs loci in the AmpFlSTR Identifiler kit (D8S1179, D21S11, D7S820, CSF1PO, D3S1358, HUMTH01, D13S317, D16S539, D2S1338, D19S433, HUMVWA, TPOX, D18S51, D5S818, HUMFIBRA/FGA and including the segment of the X-Y homologous gene amelogenin) were studied for Angola population.The genotype frequency of the 15 STR loci showed no significant deviations from Hardy–Weinberg equilibrium expectations and great values for the combined power of discrimination and combined power of a priori exclusion validate the application of these markers in forensic genetics. Comparative analyses between Angola population data and other relevant population database from Africa, Europe and American are presented.     

Y-miniSTR: New application for compromised samples (population data)

In this work 127 unrelated individuals living in the North of Portugal were typed for 8 Y-miniSTRs (DYS504, DYS508, DYS522, DYS540, DYS556, DYS570, DYS576 and DYS632). One hundred and one different haplotypes were detected and 88 of them were found to be unique. Haplotype diversity (0.9936) and discrimination capacity (69.29%) were calculated.     

Genetic data on nine STRs (CSF1PO, TPOX, THO1, F13AO1, FESFPS, vWA, D16S539, D7S820 and D13S317) and two VNTRs (D1S80 and D17S5) in Rosario population, Santa Fe Argentine

Allele frequencies for nine short tandem repeats (STRs) loci (CSF1PO, TPOX, THO1, F13AO1, FES/FPS, vWA, D16S539, D7S820 and D13S317) and two variable number tandem repeats (VNTRs) were obtained from a sample of 270 unrelated individuals born in the Rosario city, Santa Fe province of Argentina.
