Thirty species of Inoperculate Discomycetes are described herein from the Nahuel Huapí National Park (Argentina), distributed among thirteen genera belonging to the following families: Hyaloscyphaceae, Dermataceae, Sclerotiniaceae y Helotiaceae. Three of them, namely, Calloria, Sphagnicola and Phaeohelotium are recorded for the first time for Argentina. Of the thirty species found, fifteen are new records for this country. The following new combinations are proposed: Cyathicula chlorosplenioides (Speg.) Gamundí (basinym: Helotium chlorosplenioides Speg.); Rutstroemia megalospora (Speg.) Gam. (bas.: Helotium megalosporum Speg.) y Rutstroemia microsperma (Speg.) Gamundí (bas.: Helotium microspermum Speg.). The paper contains a critical study of type material from Spegazzini's herbarium, and the description of a new species of the same general area: Phaeohelotium castaneum. [ABSTRACT FROM AUTHOR]

This paper deals with the taxonomic study of soil algae in the surroundings of Buenos Aires (Argentina). Sixty-five species are studied. They belong to sixteen genera of Cyanophyceae distributed in five families and two Orders, and twenty genera of Chlorophyceae distributed in twelve families and six Orders. Among Cyanophyceae the family Oscillatoriaceae is the best represented with six genera and twenty species; among the Chlorophyceae, the Chlorococcaceae with six genera and eight species. The species Phormidium frigidum, Ph. subtruncatum, Ph. rubriterricola, Ph. papy raceum, Hydrocoleum brebissoni, Anabaena fertilissima, Tolypothrix brevis, Plectonema gracillimum (Cyanophyceae) and Chlamydomonas gloeopara, Bracteococcus minor, B. giganteus, Chlorococcum pinguideum, Chlorella fusca var. fusca, Ch. saccharophila var. saccharophila, Ch. zofingensis, Ch. minutissima and Klebsormidium subtile (Chlorophyceae) are new records for Argentina, and so are the genera Coccomyxa, Klebsormidium and Pleurococcus (Chlorophyceae). They are described and the species illustrated. Keys are given for the identification of the orders, families, genera and species. [ABSTRACT FROM AUTHOR]

This paper deals with the systematic study of the genera Calycorectes, Hexachlamys, Myrciaria, Paramyrciaria, Plinia and Siphoneugena, which represent the subtribe Eugeniinae Berg, in the Argentine flora The paper also present an enlargement of the area of distribution of Myrciaria tenella (DC.) Berg, which up to now has only been mentioned in the NW of Argentina. Paramyrciaria delicatula (DC.) Kausel is accepted instead of Myrciaria delicatula (DC) Berg, because this species has embryo with two plane-convex cotyledons and a circumcised, elongated hypanthium The new combination Plinta baporeti (Legrand) Rotman, is proposed for a species caracteristic of galleria forests The name Plinia trunciflora (Berg) Kausel has been accepted, in its author's true sense, for a species which up to now has only once been collected in Argentina. Descriptions and illustrations of every species of Hexachlamys, Siphoneugena and Calycorectes are given. Guapurium peruvianum Poir, remains as an entity of doubtful taxonomic position. It has been collected on many an opportunity, but its embryonic morphology is difficult to interprete because it shows polyembryos which, so far, have not allowed correct interpretation of this entity.

This paper is a taxonomic revision of the genus Polygonum L in Argentina, with a discussion of the morphological characters of taxonomic importance, a description of the genus and a classification of the 20 species treated in 5 Sections. Polygonum (5 species), Amblygonon Meisner (1 species), Persicaria Meisner (11 species), Echinocaulon Meisner (2 species) and Tiniaria Meisner (1 species). For each species a description, illustrations of interesting characters, geographical distribution, observations and conclusions about the study of the type material, the information about karyology, phenology and probable uses are included. Some species or varieties previously cited for Argentina have been reduced to synonymy (Polygonum meisnerianum var. beyrichianum, P. lanigerum, P. portoricense, P. acuminatum var. microstemon and var. glabrescens, P. punctatum var. aquatile, P. berteroi, P arenastrum, P. persicarioides, P. cordobense and P. rivulare), P. polygaloides, P. spergulariaeforme and P. tenue are taxa erroneously cited for our country, while P. dumetorum is considered of doubtful presence in Argentina.

This is the first paper of a chemotaxonomic serial studies of the subtribe Phaseolinae in Argentina, wich comprises the generic complex Phaseolus-Vigna-Macroptilium. Chromatographic patterns of 8 species of the genus Macroptilium were determined. Cluster analysis and ordination by principal coordinates analysis were applied to 36 chemical characters ("spots") leading to two distinct groups. These results corroborate the previous taxonomic treatment for this genus based on morphological and palynological studies. Chemical evidence seems to support the sections Macroptilium and Microcochle proposed by Lackey according to Piper, as well as the natural grouping of the species in each of these taxa.

In this contribution, the first references of 3 taxa for the Argentina fern-flora are given: Cheilanthes cucullans Fée from Salta, Blechnum (Lomaridium) kunthianum C. Chr. and Pteris sericea (Fée) Christ from Misiones. Also the taxonomic and morphological references of Pellaea sagittata (Cav.) Link var. sagittata, mencioned in a recent ethnobotanic paper, are given. Each species is illustrated in detail and some palinological data, supporting the apogamy in the type variety of Pellaea sagittata, are briefly discussed. [ABSTRACT FROM AUTHOR]

This is the second paper of a chemotaxonomic serial study of the subtribe Phaseolinae Benth. in Argentina, which comprises the generic complex Phaseolus-Vigna-Macroptilium. Chromatographic patterns of 8 species of the genus Vigna Savi were determined. Cluster analysis and ordination by principal coordinates analysis were applied to 34 chemical characters (flavonoids). Chemical evidence seems to support the taxonomic treatment proposed by Maréchal, Mascherpa & Stainier (1978b) for the American Vigna. Argentinian species of the large subgenus Sigmoidotropis can be grouped according to the sections proposed by these authors. Taxonomic distance between V. peduncularis and V. luteola, the only pantropical representative of the typically African subgenus Vigna, suggested that the section Pedunculares of the subgenus Sigmoidotropis is the nexus between these two groups. Closely related to Sigmoidotropis, the subgenus Lasiospron shows a different affinity with the section Caracallae: V. longifolia is neared to V. hookeri (Caracallae-Sigmoidotropis) than V. lasiocarpa, the other species of Lasiospron. These results are in agreement with the morphological differences observed between both species, and suggest the possibility of introducing two sections in this group. [ABSTRACT FROM AUTHOR]

This is the third paper of a series of chemotaxonomic studies of the subtribe Phaseolinae in Argentina, which comprises the generic complex Phaseolus-Vigna-Macroptilium and the nearly genus Dolichopsis. Chromatographic patterns of 1 species of the genus Dolichopsis and 3 species of the genus Phaseolus were determined, including Phaseolus vulgaris var. aborigineus and primitive landraces and wild forms of Merlo (San Luis), the southernmost locality ever reported for the common bean Cluster analysis and ordination by principal coordinates analysis were applied to 31 chemical characters («spots»). These results corroborate the taxonomic position of these species, according to Maréchal, Mascherpa & Stainier (1978) and Lackey (1977, 1983), who proposed the section Euphaseolus, and supported the fact that Dolichopsis is a genus relatively distant from Phaseolus, and more closely related to Vigna and Strophostyles.

This paper deals with the epiphytic algae found in a channel and in an artificial pond in Estación Experimental INTA Delta (Buenos Aires, Argentina). These algae are in relation with a carp population that feeds on them in their early stages. A total of 21 taxa were identified. One was a new taxon, Uronema elongatum Hoodgetts var. robustus L. Mercado et Vigna, and six are new records for Argentina. Among the Cyanophyceae, the 60% were associated algae whereas the rest were epiphytic on emergent macrophytes. The coccoid Xantophyceae were found on filamentous Chlorophyceae, whereas the filaments themselves were epiphytic on emergent macrophytes. [ABSTRACT FROM AUTHOR]

This paper deals with theoretical and practical aspects of historical socio- linguistics. After a brief consideration of its goals, methodology, and the sources required for the construction of pertinent corpora, two important aspects of the evolution of Spanish in the Buenos Aires region are considered: the standardization of Spanish from the sixteenth century up to the twentieth century, and the evolution of address forms. Concerning the first topic, the author shows the decline of a group of phonic features normally considered as "vulgares y rústicos" (Lapesa 1980) and associated with the progress of standardization observed by means of the methodological tools of flexible stability and intellectualization. Concerning the second, a wide restructuring of address forms initiated about 1850 and continuing up to this century is presented. [ABSTRACT FROM AUTHOR]

In the late nineteenth and early twentieth century, a mass inmigrant flow reshaped Argentine demography. A particularly high percentage of foreigners settled in the southwest of the province of Buenos Aires, where a complex multilingualism was generated. Nevertheless, an accelerated substitution of original languages took place in a few decades, and nowadays Spanish is the only language spoken by the majority of the population. Against that background, Danish and Volga-German communities stand out because of their prolonged conservation of their immigrant languages, which continues to the present. In this paper, we offer a review of both groups' linguistic behavior, with the purpose of analyzing the common factors that in both cases have contributed to producing the nontypical result referred to.

This paper reviews the role of vegetables -- especially fresh vegetables -- in the traditional eating behavior for people living in the outskirts of the city of Buenos Aires. Through qualitative techniques the following items are put forward: a. consumption habits and preferences, b. combinations, c. preparation. By means of the review of this information, the possibility to expand the consumption of products in this industry is put forward, on the basis of the lack of hurdles, both symbolic and of effective access, is determined. There are, however, certain limitations in relation to preparation and information techniques. [ABSTRACT FROM AUTHOR]

Mercosur, a common market comprising Argentina, Brazil, Paraguay and Uruguay, tends to derogate tariffs, non-tariff barriers and to adopt a shared foreing trade tariff. It also promotes production factors' free mobility and a shared trade policy. The integration process will have deep consequences throughout our countries' economies, including sheep husbandry and marketing. This paper includes a brief summary of the characteristics of Mercosur's sheep husbandry, with a review of its development possibilities so as to then produce a critique of the gene improvement goals and strategies in place. [ABSTRACT FROM AUTHOR]

The Argentinean Mesopotamia involved in sheep husbandry mainly encompassess the North of the Province of Entre Ríos and the South of the Province of Corrientes, where the natural pasture is the only forage supply. The existing breeds are used for both purposes, wool being the most important production item and meat being considered a by-product. The INTA Agricultural and Cattle-Breeding Experimental Station in Concepción del Uruguay includes in this paper alternatives in order to develop different lamb production systems and alternative procedures to market the product in order to promote continuous mass consumption.

The genus Baccharis is represented in Argentina by 96 species, the infrageneric classification of which is presented in this paper. A succinct summary of the history of Baccharis infrageneric taxonomy is provided. The 96 Argentine species are placed into 15 sections: Angustifoliae, Aristidentes, Baccharis, Caulopterae, Cuneifoliae, Cylindricae, Discolores, Molinae, Nitidae, Oblongifoliae, Paniculatae, Pedicellatae, Pseudobaccharis, Subliguliflorae -sect. nov.- and Trinervatae. These sections are briefly described, and a key to differentiate them is given. Twelve out of the 96 species are positioned into the infrageneric classification system for the first time, whereas 42 species which had been previously classified are here relocated to other sections. Twenty-two generic, subgeneric, sectional and subsectional names are considered as new synonyms. The relationships among the sections are discussed. [ABSTRACT FROM AUTHOR]

The objective of this paper is to provide a brief characterisation of the changes that have taken place in the Educational System of La Pampa province since the implementation of the educational reform in Argentina during the last few years. In view of the need to identify and conceptuslise these processes of change in La Pampa's model, we decided to approach the theme of the institutional organisatlen and, more specifically, the implementation of the Third Cycle of the General Basic Education and the PoUmodal, with the intention that this article will make it possible for both students of Education and other readers to construct interpretative hypotheses regarding the Educational Reform. We chose to undertake a bibliographical Jnvestigatidn. We aleo included contributions that arose from our experience in the area of Education. Working as school teachers atiows US to form interpretations of the possible implicatlens on Education because we are the ones that apply the legal framework in order to transform the educaticnal system.

This paper Is included in a research project which aims at clarifying some aspects of the historical process by which the educational system of la Pampa was structured. Focusing on the analysis of the relationship that was established between the civilian society and the state, we base our work on the supposition that the homogeneous image that the educational system acquires is more the result of a process than the process itself. We focus our article on the analysis of some state regulations and their impact on the Territory, between the end of the 19th century and the beginning of the 20th. We ask ourselves: "Was the process of construction of the educational system in la Pampa a "reflection" of national policies or is it possible to identify certain particularities?" "Which continuities, interruptions and contradictions is it possible to establish between the norms created in the central organizations and the conditions --and possibilities- of fulfilling those norms in the Territory?". Such conditions are connected with a 'diffused' presence of the National State. This presence was made effective, in the field of education, through the inspectors who - we sustain- acted as a "hinge" between the rules sent from the Capital and the local needs.

This paper analyzes some aspects related to the public debate about immigrant population and the construction of a national identity in Argentina during the first decades of the 20 th. century. Immigration, education and nationalism were the thee ideas which originated the debate on a possible model of country and constituted a field of tensions that covered the period of the great immigration wave. This paper will, in the light of these reflections, illustrate some of the features that these aspects acquired in a rural area. Southeast of the province of La Pampa the largest number of migratory population was farmed by groups of people who migrated from eastern Europe. The presence of Jewish colonies, such as the Narcisse Leven colony, meant the birth of debates on these groups which seemed to question the basis of the "Argentine Nationality". This text emphasizes the complexs relationship among immigration, education, and ethnicity. [ABSTRACT FROM AUTHOR]

This paper deals with the process of settlement in a zone of the south frontier of Buenos Aires province, the Azul brook one, which -differently from other areas of Buenos Aires field- was driven by the Provincial State of Buenos Aires throughout a sequence of conditioned donations of small and medium portions of lands which were developed by the Rosas government since 1830. These donations contributed to the settlement and the production labor of these lands by civil population that settled there and that generated relationships with the indigenous comunities established in the zone, who were articulated to the policy of the "negocio pacífico de indios" ("pacific deal of indians").

This paper attempts to analyze the Argentinian official politics for the settlement of the indigenous survivors to the military campaign (1879-1885) and its results, focusing in the study of the genesis, organization and development of the pastoral colony Emilio Mitre in La Pampa Territory, during the first decades of its existence.

The aim of this paper is to contribute to the characterization of the rioplatense rural world in the first half of the nineteenth century by the analysis of the colonization process in an area situated in the south of Salado River in present Buenos Aires province. We circumscribe our work in time and space focusing on Dolores District (with a larger surface than the present one) between 1789 and 1860. The characterization of the process to access to the usufruct and to the legal property of land in the area added to the social and demographical analysis of the population (Mascioli, 1999) expects to be a contribution to the above mentioned topic. The case studied is far from being a paradigamatic example of the "expansion of livestock breeding" that would have taken place in latifundia owned by a few owners (a familiar image when we talk about an area situated in the south of Salado River in times of the colonization process between the end of the eighteenth cen the process studied are evident: to usufruct and to access to the legal property of land in Dolores implies the possibility to transit different ways for producers with different possibilities and necessities. Besides, the reconstruction of the process will let us compare it with others that took place in other lands and time, in order to explain the occupation of the pampeano surface in a diachronic perspective.

In previous papers we have analyzed police functions, purposes and norms as agencies of social control; historical and structural impediments in the police-state relationship and in the formation of political programs, experiences with community models of urban security and its practical results in Argentina, etc. In this paper we will emphasize the consideration of violence as a constituent element of police culture, and even more so in a police state, in its semantic multiplicity: legal, abusive, extralegal diffuse, symbolic violence (Tavares Dos Santos, 2000). On the other hand we study the construction of the "suspect" population and of the types of delinquency, realizing a critical analysis of the typologies of crime and delinquency, determining the manner in which official statistical analysis is made (what the penal and political system understand) and visualizing the omissions they include in an attempt to explain the same. (It is interesting to analyze statistics searching for the holes in empirical analysis in reference to the questions proposed and not because we are excessively positivist) It is necessary to have as a back-drop the overlapping of political programs and their consequences: one of these programs, one of zero tolerance, according to Crawford, is an erroneous and discriminatory designation of groups, which converts these happenings into selective intolerant events. Examples: the technique of "halt and frisk" and "class-cleansing" techniques in public areas and the overlooking of certain typologies such as administrative crimes, commercial fraud, contamination and health and security infractions (Wacquant, 2000). Finally we present the manner in which this selective intolerance is translated in the country, beyond political and media discourse ambiguity ("cero tolerance" is not assumed to be continually sustained) which worsen the situation of violence and criminality in the framework of a high exclusive social and economic model in which strategies are the repetitions of repetitions of reforms, grand rhetoric and technical terminology which conjecturally circle about while society observes and is absorbed in this "dislocated scenario" managed by an uncertain state.

In the South of Cordoba province, Argentine, the pleistocene zone of Sampacho is located, where the active fault Las Lagunas is situated. This probably generated the seismic crisis of 10th June 1934, with the occurrence of two earthquakes of M5.5 and M6. Modifications in Radon gas emissions (Rn 222) and increases in the microseismic occurrence are considered as precursor geoindicators in areas under seismic hazard. Anomalies in this gas emission levels, as well as an increase in the microseismic activity were detected in the pre-seismic stage of the earthquakes that occurred in Japan, USA, Italy, Mexico and the former Soviet Union. The objective of the present paper is to monitor the radon gas emissions in order to establish its relation to the microseismic activity in an area nearby a section of the active fault Las Lagunas, by means of the Track-Etch technique and to try to establish a seismic precursor geoindicator for it. As a conclusion, it was proved that there exist relations between the changes in the Radon gas emission and the local seismic activity, and between the variation of emission level and the size of superficial light earthquakes, that have occurred in the record period.

Urban life, as opposed to rural life, is a form of socio-cultural interaction characterized by its tendency to promote , anonymous and extra-family relationships. The city tends towards specialization and heterogeneity. Journalistic discourse constitutes a way of urban articulation that stimulates interactions and contributes to the construction of processes of socio-cultural identification. This article is part of a wider project whose aim is to search the ways in which journalistic discourse was constructed in relation to socio-cultural identification in the city of Buenos Aires in the period 1800-1825. In this paper the mechanisms of identity formation in Buenos Aires and their interaction with the socio-political, socio-economical and socio-cultural spheres are analyzed from evidence appearing in the first River Plate newspaper, Telégrafo Mercantil, edited in 1801 and 1802. Beginning with an analysis of the key words, we set to search Buenos Aires urban imaginary, which the newspaper contributes to reinforce as a site of collective interaction. The city appears as a social, political, economical and cultural projection, which highlights the importance of Buenos Aires and contrasts it with life in the countryside presented as of inferior hierarchy. Thus, an urban project is developed, related to elements of belonging and identification, which cannot be equaled in its realization. [ABSTRACT FROM AUTHOR]

This paper is an attempt to look into the visibility of women and their link with the Peronista government during its first two administrations (1946-1952 and 1952-1955). We focus our analysis on the relationship many women established with Eva Perón during their participation in the Peronista political organization. Following the methodology of oral history, we collected data via personal interviews to a Peronista woman related to the Eva Perón Foundation. Through her reports we have been able to visualize social practices that helped us understand the function of this institution beyond the scope of discourse. In this sense, we were able to reconstruct a Peronista woman's working and political path, her social representations regarding the figure of Eva Peron and the changes that signaled a crucial period in women's history: the implementation of the feminine vote.

This paper focuses on the revision of the journalistic coverage given to the conflict caused by the Argentine troops' occupation of the South Atlantic Islands, which ended in an army contend with England, by the two main Spanish newspapers: El Pais and ABC. The paper highlights the implication that this confrontation had for Spain that was at the height of its democratization process. Not only did Spain have a close link with Argentina but it had also experimented a similar conflict in the Rock of Gibraltar. Besides, by the time of the conflict, the Spanish government had started an approaching strategy towards Europe, and was facing one of the first demonstrations against its decision to join the of N.A.T.O. Furthermore, the Argentine dictatorship had become a subject of preferential attention and damnation as a consequence of charges raised against its continuous violations to human rights.

This paper intends to describe the managing characteristics shared by schools of the first and second Basic General Education levels as a result of the implementation of the educational reform in La Pampa. To the purpose of this research, we analyzed the institutional guidelines set by headmasters and compared the conclusions stated in our previous research (1995-1999) with results from recent case studies. In most of the schools included in our sample we observed the recurrence of similar skewed contextual readings and managing practices. These particular managing styles reflect the principals' key role in the adaptation of the Institutional Educative Projects (IEP), requested by the central administration, to the different schools' needs. As a conclusion, we can say that, despite the institutional difficulties faced by those in charge of managing positions, the school headship is the possible space where to generate deconstructing and reconstructing policies via alternative projects and managing groups who can reconsider our institutional history and provide a new significance to the established educational practices.

This paper studies the role performed by the parsons as ecclesiastical judges in the Buenos Aires rural parishes during the last colonial decades. For such purpose, we analysed the regulation relating to their functions in the judicial environment as well as the effective exercise of these tasks. Particularly three fields of action of these parishes-judges are considered: marital control, the administration of the right of "asilo en sagrado", and their intervention in testamentary dispositions. The period in which we center the research is crossed by the tension that meant the reduction of competences carried out by borbonic policies. In response to these regalist measures, we will see clergymen either deprived of some judicial functions, keeping others, or resisting the reduction of some tasks that, until that moment, were in their hands. As it would happen in other areas, also in the excercise of justice, parishes and mayors will share some functions and -not unfrequently- will compete for the control of the institutional power at local levels.

In this article, we offer a contribution to the social history of punishment, attending to a historical approach upon the pagatonic prison of Neuquen (U.P.9). The main topics are both the inmates' material life and the penitentiary policies displayed in this prison, with the purpose of showing the different ways in which the small local prison's bureaucracies interpreted and executed national regulations. Social features of the inmates are sketched, focusing specially upon the differences between common and political prisoners. This paper tries to discuss the supposed depth, coherence and regularity that literature usually attributed to the Argentine's positivist, late nineteenth Century penitentiary's reforms. Neuquén's prison is compared with the much bigger and well-provided Ushuaia's prison, settled in the southern areas of Argentina. [ABSTRACT FROM AUTHOR]

This paper is an enquiry into the strategies for access to land displayed by the Russo family, rural producers who, by the end of the nineteenth Century settled as cattle tenants on southern areas of the Territorio Nacional de La Pampa. Through the analysis of sources belonging to the private archive of the family and other public documents, we reconstructed different moments in the life of the Russos, marked by the strategies carried through to economically settle themselves and maximize opportunities by combining tenancy-property, stability factors and the scale of tenancy. In diverse areas for two generations. This case study, focused upon the family and located in a zone with characteristics that differ from those sketched in the bulk of dominant historiography, allows to shed light on issues concerning the access to land by pampean rural producers at the end of the nineteenth Century and the first decade of the twentieth, and thus, discuss some traditional postulates, besides from establishing the existence of regional variations.

In this paper, the impact of the transnationalization in Economy localization patterns of the urban activities in an intermediate city -Mendoza, Argentina- and in a city linked with the global economy-San Pablo, Brasil- is evaluated. This study is based on the retrospective and comparative analysis of the aspects related to the land use and to the population, stemming from the definition of geographical typologies and geographical associations. It has been established that the distribution patterns differ according to the consideration of "traditional" or "new" activities. Also, the territorial transformation and the process that originates them are considered. Among the conclusions, it is important to underline the existence of similarities between the localization patterns of urban activities in both cities, although there is a difference in there magnitudes. As a difference between both cities it is noted that while in one of them diversification prevails, in the other specialization develops. [ABSTRACT FROM AUTHOR]

This paper deals with the profesional development of Secondary School teachers in work settings. It focuses on the development of teachers as human beings and professionals, whose lives and work are shaped by internal and external school conditions. This paper does not aim at making a generalization but at unveiling those clues that might help in the promotion of development of secondary school teachers. This will be done through categories evolved for a better understanding of the object of study. For this qualitative piece of research twelve cases in the city of Córdoba have been analized and a particular kind of interview -life stories has been applied. [ABSTRACT FROM AUTHOR]

The aim of this paper is to show the continuity and ruptures that originated in educational institutions when the Third Cycle was implemented in the EGB (Basic General Education) after the analysis of the curricular political and organizational levels carried out in three public institutions in General Pico, La Pampa. The purpose of this paper is to reveal the complex mechanisms under which the processes or reform are installed in the practices, as well as the intertwining produced between the official curricular proposals, the institutional projects and the teaching of the Social Sciences. On the other hand, and given the exiguous empirical studies on the implementation of the Third Cycle in the country, the paper contributes with enlightment on the different levels under study, the obstacles, achievements and resistances the actual agents admitted having experienced, as well as the existing gap between the official messages and the pedagogical practices developed in the classrooms. The study shows that the methodological and organizational realities are different in each school, while in each classroom, there appeared certain regularities in the three cases under analysis when considering the pedagogical proposals regarding the Social Sciences.

The goal of this paper was to make a diagnosis of the composition and conservation status of vertebrates and their habitats in the Castaño River. Vulnerable species and critical areas that show an old mining tradition were defined. The methodology was organized considering: 1) inventory, and 2) evaluation of habitats and conservation status. The 63 vertebrate species found were classified as: 1 fish, 2 frogs, 5 reptiles (4 lizard and 1 snake), 51 birds and 4 mammals. Habitats occupied by fauna were delimited and classified as: a) hydrophytic communities and riparian forest, and b) xerophytic shrub steppe. Each habitat was stratified and active species occupation was estimated. In relation to the conservation status of birds, 37 % shows some problem. Critical areas used by birds, mostly as nesting and rearing places, are suggested. [ABSTRACT FROM AUTHOR]

The city of Sampacho, situated in Río IV departmen, center of Argentina, it is located in an intraplate region with proved historical and current seismic activity, where the level of seismicity, which is important, makes a low constant seismic geoamenace to the all region. It is worth mentioning that it was epicenter of two historical earthquakes (year 1934), considerated two of the most destructive ones within of the zone of reduced seismicity. In this paper characterizes preliminarily the Seismic Susceptibility in the sourrounding areas of Sampacho City, as a base for future studios of seismic microzoning and evaluation of Seismic-Risk. The following metodology emphatized the local lithologic, geomorphologic and hydrologic factors, which may have an important incidence in the displacement of elastic wave front. It also defines five classes of susceptibility from superimpose of information levels (lithology and depth of level freatic), from wich the moderately low prevails. The areal distribution of them is presented in a preliminary Map of Seismic Susceptibility in digital support, being this one the first document developed on this theme for the region.

This paper is a comprehensive analysis of Argentinean historiographic memory as regards the condition of women and gender studies. It is a state-of-the-art work on the historical discipline in this field and refers both to the precursory works from before the 1980's and to the activities carried out by an ever-increasing number of agents, at the moment when historiography was legitimated in our country, by the mid 80's. This expansion coincides with a series of phenomena, both internal and external, among which we may point out the outstanding renewal and spread of feminist studies, epistemological changes, transformations in social history, the international growth of gender historiography, together with the social and political changes that took place in Argentina with the return of democracy and the new approaches introduced in the academic context with the advent of studies on women and gender. There exists a conceptual attempt to typify these contributions which evince both their lines of strength and also those aspects still awaiting historical probe. [ABSTRACT FROM AUTHOR]
