The production of school numbers (1871-1931): contributions to a critical approach to statistical sources in History of Education

This article intends to contribute to the reflection on the Educational Statistics as being source for the researches on History of Education. The main concern was to reveal the way Educational Statistics related to the period from 1871 to 1931 were produced, in central government. Official reports - from the General Statistics Directory - and Statistics yearbooks released by that department were analyzed and, on this analysis, recommendations and definitions to perform the works were sought. By rending problematic to the documental issues on Educational Statistics and their usual interpretations, the intention was to reduce the ignorance about the origin of the school numbers, which are occasionally used in current researches without the convenient critical exam.

La guerre contre-insurrectionnelle guatémaltèque : sa généalogie, le déni des responsables et les sources historiques

L’Amérique centrale, théâtre des dernières batailles rangées de la guerre froide, est aujourd’hui la région la plus violente au monde, selon les Nations unies. Notre étude s’intéresse à la forme de guerre irrégulière livrée par l’État guatémaltèque contre sa propre population pendant la deuxième moitié du vingtième siècle. À la lumière de rares témoignages d’exécutants et d’archives militaires et policières, nous examinons un mécanisme clandestin de répression dont les trois principales composantes – les enlèvements, la torture et les exécutions sommaires – pouvaient s’abattre sur toute personne soupçonnée, à tort ou à raison, de conspirer contre un statu quo d’exclusion. Au moment de leur articulation, ces moyens répressifs ont constitué un dispositif qui, à partir de 1966, s’est avéré d’une redoutable efficacité. Arme de prédilection des adeptes de la guerre antisubversive pendant plus de vingt ans, le dispositif permettait, telle une chaîne de production, l’accumulation des renseignements jugés indispensables à cette forme de guerre, ainsi que les cadavres dont l’absence éternelle ou la présence outrageuse sur la place publique servaient d’avertissement funeste à l’ensemble du corps social. Où chercher les origines d’un tel dispositif? À partir des ouvrages de référence cités dans le manuel de guerre contre-subversive de l’armée guatémaltèque, la réponse à cette question nous fera découvrir des parachutistes français pour qui la défaite militaire en Indochine et en Algérie pendant les années 1950 n’était pas une option et pour qui la victoire justifiait absolument tous les moyens. Le penchant de ces pionniers de la guerre hors-norme pour les cours magistraux, les entrevues et les articles, nous a permis d’étudier les méthodes qu’ils préconisaient et de repérer leurs traces au Guatemala. Alors que la guerre qui avait servi de prétexte au maintien du dispositif est terminée, sa très réputée efficacité assure encore aujourd’hui sa pérennité auprès de ceux qui peuvent s’offrir le service. En ce sens, la contre-insurrection se poursuit, et ce, malgré l’absence depuis une quinzaine d’années d’un conflit armé. Cette thèse aborde l’histoire de la guerre irrégulière et son déroulement au Guatemala. Les archives et les témoignages à notre disposition contredisent le déni des crimes commis dans les villes et les campagnes guatémaltèques, dont le génocide de 1982. Finalement, certains signes avant-coureurs indiquent que la violence et l’impunité actuelles au pays pourraient mener à la répétition de tels crimes à l’avenir.

Two historical maps from nineteenth-century Palestine, with links to digitized maps in shapefile format

Reconstructing past landscapes from historical maps requires quantifying the accuracy and completeness of these sources. The accuracy and completeness of two historical maps of the same period covering the same area in Israel were examined: the 1:63,360 British Palestine Exploration Fund map (1871-1877) and the 1:100,000 French Levés en Galilée (LG) map (1870). These maps cover the mountainous area of the Galilee (northern Israel), a region with significant natural and topographical diversity, and a long history of human presence. Land-cover features from both maps, as well as the contours drawn on the LG map, were digitized. The overall correspondence between land-cover features shown on both maps was 59% and we found that the geo-referencing method employed (transformation type and source of control points) did not significantly affect these correspondence measures. Both maps show that in the 1870s, 35% of the Galilee was covered by Mediterranean maquis, with less than 8% of the area used for permanent agricultural cropland (e.g., plantations). This article presents how the reliability of the maps was assessed by using two spatial historical sources, and how land-cover classes that were mapped with lower certainty and completeness are identified. Some of the causes that led to observed differences between the maps, including mapping scale, time of year, and the interests of the surveyors, are also identified.

Referential hierarchies: A new look at some historical and typological patterns

This paper proposes a diachronic typology for the various patterns that have been referred to as Hierarchical Alignment or Inverse Alignment. Previous typological studies have tried to explain such patterns as grammatical reflections of a universal Referential Hierarchy, in which first person outranks second person outranks third person and humans outrank other animates outrank inanimates. However, our study shows that most of the formal properties of hierarchy-sensitive constructions are essentially predictable from their historical sources. We have identified three sources for hierarchical person marking, three for direction marking, two for obviative case marking, and one for hierarchical constituent ordering. These sources suggest that there is more than one explanation for hierarchical alignment: one is consistent with Givón’s claim that hierarchical patterns are a grammaticalization of generic topicality; another is consistent with DeLancey’s claim that hierarchies reflect the deictic distinction between present (1/2) and distant (3) participants; another is simply a new manifestation of a common asymmetrical pattern, the use of zero marking for third persons. More importantly, the evolution of hierarchical grammatical patterns does not reflect a consistent universal ranking of participants – at least in those cases where we can see (or infer) historical stages in the evolution of these properties, different historical stages appear to reflect different hierarchical rankings of participants, especially first and second person. This leads us to conclude that the diversity of hierarchical patterns is an artifact of grammatical change, and that in general, the presence of hierarchical patterns in synchronic grammars is not somehow conditioned by some more general universal hierarchy.

Chemical characterization of soil organic matter in an oligotrophic, subtropical, freshwater wetland system: Sources, diagenesis and preservation

Freshwater wetland soils of the Everglades were studied in order to assess present environmental conditions and paleo-environmental changes using organic geochemistry techniques. Organic matter in dominant vegetation, peat and marl soils was characterized by geochemical means. Samples were selected along nutrient and hydrology gradients with the objective to determine the historical sources of organic matter as well as the extent of its preservation. Effective molecular proxies were developed to differentiate the relative input of organic matter from different biological sources to wetland soils. Thus historical vegetation shifts and hydroperiods were reconstructed using those proxies. The data show good correlations with historical water management practices starting at the turn of the century and during the mid 1900's. Overall, significant shortening of hydroperiods during this period was observed. The soil organic matter (SOM) preservation was assessed through elemental analysis and molecular characterizations of bulk 13C stable isotopes, solid state 13C NMR spectroscopy, UV-Vis spectroscopy, and tetramethyl ammonium hydroxide (TMAH) thermochemolysis-GC/MS. The relationship of the environmental conditions and degradation status of the soil organic matter (SOM) among the sites suggested that both high nutrient levels and long hydroperiod favor organic matter degradation in the soils. This is probably the result of an increase in the microbial activity in the soils which have higher nutrient levels, while longer hydroperiods may enhance physical/chemical degradation processes. The most significant transformations of biomass litter in this environment are controlled by very early physical/chemical processes and once the OM is incorporated into surface soils, the diagenetic change, even over extended periods of time is comparatively minimal, and SOM is relatively well preserved regardless of hydroperiod or nutrient levels. SOM accumulated in peat soils is more prone to continued degradation than the SOM in the marl soils. The latter is presumably stabilized early on through direct air exposure (oxidation) and thus, it is more refractory to further diagenetic transformations such as humification and aromatization reactions.

Dimensions of historical empathy in upper secondary students’ essays

This article examines upper secondary school students’ understanding of historical empathy. The focus is on how and to what degree they displayed in their essays historical contextualisation, perspective taking and affective connection. The study was based on the essays written by 96 students, using resource-material that comprised background information and historical sources. The students reflected on the controversial issue of Finnish children who were sent to Sweden during World War II. All the three dimensions of empathy were expressed at some level, but contextualisation was most often superficial. The dimension the students managed best was perspective taking, which was related to the affective dimension of the topic. They also applied psychological terminology to this historical issue. It could be concluded from the findings that students need instruments for and have interest in dealing with sensitive and affective historical issues.

NEWS CONCERNING A CERTAIN TAMOIO CONFEDERATION

In this article we revisit a famous chapter of Brazilian history, yet to be properly analysed from an ethnological perspective: the `Tamoio confederation,` a coalition of 16th century coastal Tupian groups who threatened to undermine Portuguese colonization during the dispute between the French and Portuguese for the Guanabara region (now Rio de Janeiro). Was this `confederation` a new phenomenon in Tupian politics, engendered by the Conquest and inducing a shift towards political centralization? Or was it, on the contrary, the actualization of a possibility already (always) present in Tupian forms of political organization and action? These are the questions guiding our inquiry, which we seek to answer through the use of both historical sources and the in-depth ethnological knowledge of Tupi-Guarani peoples developed by various authors over recent decades.

Revision of the portuguese catalog of tsunamis

Catastrophic tsunamis are described in historical sources for all regions around the Gulf of Cadiz, at least since 60 BC. Most of the known events are associated with moderate to large earthquakes and among them the better studied is 1 November 1755. We present here a review of the events which effects, on the coasts of the Portuguese mainland and Madeira Island, are well described in historical documents or have been measured by tide gauges since the installation of these instruments. For a few we include new relevant information for the assessment of the tsunami generation or effects, and we discard events that are included in existing compilations but are not supported by quality historical sources or instrumental records. We quote the most relevant quantitative descriptions of tsunami effects on the Portuguese coast, including in all pertinent cases a critical review of the coeval sources, to establish a homogenous event list. When available, instrumental information is presented. We complement all this information with a summary of the conclusions established by paleo-tsunami research.

The 1853-1856 cholera morbus epidemic in Portugal as seen by the press

This research is part of a larger project focused on producing a History of the Popularization of Science and Technology in Portugal. The goal is to find out how scientific knowledge reached the common people in the nineteenth century, using newspapers as the main source of information. Keeping in mind the population’s limited access to written material, nevertheless each newspaper could be read daily by an estimate 30.000 people in Lisbon, which places this source as probably the most widespread vehicle to divulge the latest scientific news at the time to an unspecialised audience. With a cholera morbus epidemic which affected the second largest Portuguese town and all the northern regions, as well as the Algarve, news and reports on its evolution were considered essential. A large database was built in order to analyse the news concerning this disease in 1855 and 1856, especially the ones about prevention and treatment. These are important historical sources that give us real information on the scientific knowledge of the time and the way it was used by society.

Spectroscopic characterization of natural dyes by their non-invasive identification on pre-Columbian codices: the Maya yellow

Mesoamerican cultures had a strong tradition of written and pictorial manuscripts, called the codices. In studies already performed it was found the use of Maya Blue, made from a mixture of indigo and a clay called palygorskite, forming an incredibly stable material where the dye is trapped inside the nanotubes of the clay, after heating. However, a bigger challenge lies in the study of the yellows used, for these civilizations might have used this clay-dye mixture to produce their yellow colorants. As a first step, it was possible to provide identification, by non-invasive methods, of two colorants (a flavonoid and a carotenoid). While the flavonoid absorbed between 368-379 nm, the carotenoid would absorb around 455 nm. A temperature study also conducted allowed to set 140ºC as the desirable temperature to heat the samples without degrading them. FT-IR, conventional Raman and SERS allowed us to understand the existence of a reaction between the dyes and the clays (palygorskite and kaolinite), however it is difficult to understand it in a molecular point of view. As a second step, five species of Mexican dyes were selected on the basis of historical sources. The Maya yellow samples were produced adapting the recipe proposed by Reyes-Valerio, supporting the yellow dyes extracted from the dried plants on the clays, with addition of water, and then heated at 140ºC. It was found that the addition of water in palygorskite would increase the pH, hence deprotonating the molecules having a clear negative effect in the color. A second recipe was developed, without the addition of water; however, it was found that the use of water based binders would still alter the color of the samples with palygorskite. In this case, kaolinite without heating yield better results as a Maya yellow hybrid. It was found that the Maya chemistry might not have been the same for all the colors. The Mesoamericans might have found that different dyes could work better to their desires if matched with different clays. It was noticeable that for a clear distinction between flavonoids and carotenoids the reflectance and emission studies suffice, but when clay is added, Raman techniques will perform better. For this reason, conventional Raman and SERS were employed in order to create a database for the Mesoamerican dyestuffs for a future identification.
