La presente ponencia socializa los avances del proyecto de investigación institucional que involucra un proceso de tres años, indagando sobre las construcciones de prácticas profesionales en el campo de la Educación Física en la ciudad de Olavarría. El objeto de investigación comprende las trayectorias formativas y laborales de los Profesores de Educación Física, que construyen sus prácticas en diversos recorridos y en múltiples ámbitos donde se desarrolla la Educación Física Los Profesores de Educación Física son requeridos con reconocimiento oficial en algunos ámbitos y con reconocimiento social en otros, para desempeñar diversas tareas dentro del campo social y educativo. Este trabajo tensiona los siguientes interrogantes: ¿Cómo se configuran las prácticas en el diversificado campo de la Educación Física? ¿Cuáles son los sentidos y significados que se construyen en el interior de las mismas? ¿Qué dimensión alcanzan los conceptos: trabajo / oficio / profesión en las prácticas en EF? Para comprender estos interrogantes trabajamos con categorías teóricas de análisis construidas: ámbitos de desempeño, tipo de práctica, marcos regulatorios, condiciones materiales y simbólicas, saberes y conocimientos y discursos y relatos

El presente trabajo tiene como objetivo, describir las características de los líderes profesores de EF en dos ambientes universitarios. Se realizó una encuesta sobre una muestra de cuarenta docentes pertenecientes a dos áreas deportivas de la UNRC. El tipo de liderazgo percibido por los docentes fue evaluado con un instrumento adaptado de los modelos CELID-S, CONLID-S y CAMIN-S. El tipo de cultura se determinó evaluando cualitativamente notas de campo con entrevistas a directivos de las áreas estudiadas, siendo las culturas dominantes: Comunal y Red-Fragmentada respectivamente. Para caracterizar el liderazgo en cada grupo se realizó un análisis estadístico multivariado exploratorio por el método de Componentes Principales. Los resultados del trabajo de campo permiten concluir que los líderes de ambos grupos tienen características comunes: el carisma, la participación, el clima y la orientación a los cambio y características diferenciales: en la cultura comunal el factor más contributivo es el estilo directivo que fija metas claras y exigentes en procura del máximo rendimiento, luego mucho menos explica la orientación humanística; mientras que en la cultura en Red- Fragmentada el factor que más contribuye es el factor humano y las relaciones interpersonales resultando mucho menos contributivos la orientación a las tareas, objetivos y metas exigentes

Drilling a complete deep crustal section has been a primary yet elusive goal since the inception of scientific ocean drilling. In situ ocean crustal sections would contribute enormously to our understanding of the formation and subsequent evolution of the ocean crust, in particular the interplay between magmatic, hydrothermal, and tectonic processes. Ocean Drilling Program (ODP) Leg 206 was the first of a multileg project to drill an in situ crustal section that penetrated the gabbroic rocks of the Cocos plate (6°44.2'N, 91°56.1'W), which formed ~15 m.y. ago on the East Pacific Rise during a period of superfast spreading (>200 mm/yr) (Wilson, Teagle, Acton, et al., 2003, doi:10.2973/odp.proc.ir.206.2003). During Leg 206, the upper 500 m of basement was cored in Holes 1256C and 1256D with moderate to high recovery rates. The igneous rocks recovered are predominantly thin (10 cm to 3 m) basalt flows separated by chilled margins. There are also several massive flows (>3 m thick), although their abundance decreases with depth in Hole 1256D, as well as minor pillow basalts, hyaloclastites, and rare dikes. The lavas have been slightly (<10%) altered by low-temperature hydrothermal fluids, which resulted in pervasive dark gray background alteration and precipitation of saponite, pyrite, silica, celadonite, and calcium carbonate veins. Here we present a geochemical analysis of the CaCO3 recovered from cores. The compositions of ridge flank fluids within superfast spreading crust will be determined from these data, following the approach of Hart et al. (1994, doi:10.1029/93JB02035), Yatabe et al. (2000, doi:10.2973/odp.proc.sr.168.003.2000), and Coggon et al. (2004, doi:10.1016/S0012-821X(03)00697-6).

The sea-surface microlayer (SML) is at the upper- most surface of the ocean, linking the hydrosphere with the atmosphere. The presence and enrichment of organic compounds in the SML have been suggested to influence air- sea gas exchange processes as well as the emission of primary organic aerosols. Here, we report on organic matter components collected from an approximately 50µm thick SML and from the underlying water (ULW), ca. 20 cm below the SML, in December 2012 during the SOPRAN METEOR 91 cruise to the highly productive, coastal upwelling regime off the coast of Peru. Samples were collected at 37 stations including coastal upwelling sites and off-shore stations with less organic matter and were analyzed for total and dissolved high molecular weight (> 1 kDa) combined carbohydrates (TCCHO, DCCHO), free amino acids (FAA), total and dissolved hydrolyzable amino acids (THAA, DHAA), transparent exopolymer particles (TEP), Coomassie stainable particles (CSPs), total and dissolved organic carbon (TOC, DOC), total and dissolved nitrogen (TN, TDN), as well as bacterial and phytoplankton abundance. Our results showed a close coupling between organic matter concentrations in the water column and in the SML for almost all components except for FAA and DHAA that showed highest enrichment in the SML on average. Accumulation of gel particles (i.e., TEP and CSP) in the SML differed spatially. While CSP abundance in the SML was not related to wind speed, TEP abundance decreased with wind speed, leading to a depletion of TEP in the SML at about 5 m s-1 . Our study provides insight to the physical and biological control of organic matter enrichment in the SML, and discusses the potential role of organic matter in the SML for air-sea exchange processes.

We evaluate phosphorus (P) and biogenic barium (bio-Ba) as nutrient burial and export productivity indicators for the Late Cretaceous and early Paleogene, combining these with calcium carbonate (CaCO3), organic carbon (C), and bulk CaCO3 C isotopes (d13C). Sample ages span 36-71 Ma (~1 sample/0.5 m.y.) for a depth transect of sites in the western North Atlantic (Blake Nose, Ocean Drilling Program Leg 171B, Sites 1052, 1051, and 1050). We use a multitracer approach including redox conditions to investigate export productivity surrounding the global Paleocene d13C maximum (~57 Ma). Reducing conditions render most of the bio-Ba record not useful for export productivity interpretations. P and organic C records indicate that regional nutrient and organic C burial were high at ~61 and ~69 Ma, and low during the Paleocene d13C maximum, a time of proposed global high relative organic C burial. Observed organic C burial changes at Blake Nose cannot explain this C isotope excursion.

Snow samples collected from hand-dug pits at two sites in Simcoe County, Ontario, Canada were analysed for major and trace elements using the clean lab methods established for polar ice. Potentially toxic, chalcophile elements are highly enriched in snow, relative to their natural abundance in crustal rocks, with enrichment factor (EF) values (calculated using Sc) in the range 107 to 1081 for Ag, As, Bi, Cd, Cu, Mo, Pb, Sb, Te, and Zn. Relative to M/Sc ratios in snow, water samples collected at two artesian flows in this area are significantly depleted in Ag, Al, Be, Bi, Cd, Cr, Cu, Ni, Pb, Sb, Tl, V, and Zn at both sites, and in Co, Th and Tl at one of the sites. The removal from the waters of these elements is presumably due to such processes as physical retention (filtration) of metal-bearing atmospheric aerosols by organic and mineral soil components as well as adsorption and surface complexation of ionic species onto organic, metal oxyhydroxide and clay mineral surfaces. In the case of Pb, the removal processes are so effective that apparently ''natural'' ratios of Pb to Sc are found in the groundwaters. Tritium measurements show that the groundwater at one of the sites is modern (ie not more than 30 years old) meaning that the inputs of Pb and other trace elements to the groundwaters may originally have been much higher than they are today; the M/Sc ratios measured in the groundwaters today, therefore, represent a conservative estimate of the extent of metal removal along the flow path. Lithogenic elements significantly enriched in the groundwaters at both sites include Ba, Ca, Li, Mg, Mn, Na, Rb, S, Si, Sr, and Ti. The abundance of these elements can largely be explained in terms of weathering of the dominant silicate (plagioclase, potassium feldspar, amphibole and biotite) and carbonate minerals (calcite, dolomite and ankerite) in the soils and sediments of the watershed. Arsenic, Mo, Te, and especially U are also highly enriched in the groundwaters, due to chemical weathering: these could easily be explained if there are small amounts of sulfides (As, Mo, Te) and apatite (U) in the soils of the source area. Elements neither significantly enriched nor depleted at both sites include Fe, Ga, Ge, and P.

In the geosphere, germanium (Ge) has a chemical behavior close to that of silicon (Si), and Ge commonly substitutes for Si (in small proportions) in silicates. Studying the evolution of the respective proportions of Ge and Si through time allows us to better constrain the global Si cycle. The marine inventory of Ge present as dissolved germanic acid is facing two main sinks known through the study of present sediments: 1) incorporation into diatom frustules and transfer to sediments by these "shuttles", 2) capture of Ge released to pore water through frustule dissolution by authigenic mineral phases forming within reducing sediments. Our goals are to determine whether such a bio-induced transfer of Ge is also achieved by radiolarian and whether Ge could be trapped directly from seawater into authigenic phases with no intervention of opal-secreting organisms (shuttles). To this end, we studied two Paleozoic radiolarite formations and geological formations dated of Devonian, Jurassic and Cretaceous, deposited under more or less drastic redox conditions. Our results show that the Ge/Si values observed for these radiolarites are close to (slightly above) those measured from modern diatoms and sponges. In addition, our results confirm what is observed with some present-day reducing sediments: the ancient sediments that underwent reducing depositional conditions are authigenically enriched in Ge. Furthermore, it is probable that at least a part of the authigenic Ge came directly from seawater. The recurrence and extent (through time and space) of anoxic conditions affecting sea bottoms have been quite important through the geological times; consequently, the capture of Ge by reducing sediments must have impacted Ge distribution and in turn, the evolution of the seawater Ge/Si ratio.

This article evaluates the performance of public service broadcasters in the area of children’s television in Italy and Spain. It asks: how distinctive is the output of public service children’s channels? As core area of public service provision, children’s television represents an important testing ground for wider debates about the distinctiveness of public service broadcasting in a digital age. Public broadcasters in Southern Europe have historically been more vulnerable to market pressure than their counterparts in continental and Northern Europe, and this is believed to have impacted negatively on their ability to maintain a distinctive public service profile. After engaging with debates on distinctiveness in order to develop a framework for the analysis, the article presents the results of a two-week analysis of the TV schedules of the main children’s channels operating in the two countries. It finds evidence that in both countries the output of public service children’s channels is distinctive to a degree, but also that there are important gaps in public service provision as well as some significant differences between the public service children’s channels analysed.

This paper will examine familiar reasons for including the teaching of intercultural competence within Language Teaching before adding some less familiar ones. It will focus in particular on the question of how far intercultural competence can be learned when students are formally studying languages and how far such competence needs to be acquired autono-mously. It will though also ask to what extent being initiated to the very varied facets of in-tercultural competence during formal language study plays an important role in allowing ef-fective autonomous acquisition to take place. The paper will conclude that a significant part of the intercultural development that students need to undertake if they are to be able to communicate effectively in a foreign language must happen autonomously, but that it is, nonetheless, vital that language courses at least sow the seeds of intercultural learning in ways that will facilitate autonomous learning. As such, language courses, if they are genuinely to meet student needs, should incorporate elements of intercultural training. The paper also concludes by outlining the type of empirical research that would need to be carried out for these claims to be fully substantiated.

In the context of demands by the European feminist movement at the beginning of the 20th century, in Spain women’s sport flagged up aspirations to what were considered to be male practices. The first experiences of women in football stand out because of their use of the media to appear as a symbol of social transformation to modernity in the 20th century. It was not in vain that women’s football highlighted the demands of the feminist movements, although it did come up against male disapproval from an opposing group. The research sets out from a bibliographical and media review of specialist press and sports news of the time. Other current studies have also been considered in order to place it in a social and historical focus on sport. This has enabled us to highlight that football in Spain was established as an unequivocal space for (re) producing male hegemony where women were relegated to the representation of a symbolic ritual in a scenario of accessory and condescension.

Objective: Identify preventive self-care practices and analyze the configurations of the network support for women with and without breast cancer registered in a mammography-monitoring project from Porto Alegre/Brazil.Method: a mixed sequential delimitation was performed, which expanded the results of the quantitative step (cross and correlation section) in a qualitative step (narrative interviews). 37 women diagnosed with breast cancer (group 1) and 72 without this diagnosis (group 2 – monitoring) participated. The following instruments were used: Assessment Questionnaire Self-care Ability (ASA-A) and Assessment Questionnaire Perceived Social Support and Community. There were performed descriptive analysis and comparison of means (t test and ANOVA) between the two groups. To deepen the understanding of the data, we selected four women with breast cancer with extreme levels on the scale of Social Support to participate in the biographical narrative interviews.Results: the analysis indicate that women who had breast cancer have better self-care practices than the women from the monitoring project (t = 1.791, P = 0.027). As for the analysis of social support, there were no statistically significant differences between the two groups. All participants have an average level of perceived social and community support. It was highlighted by the qualitative data that it was after the diagnosis of breast cancer that women lived self-care aspects they had not previously experienced.Conclusions: the self-care was significantly bigger in the group of women with breast cancer, where the cancer diagnosis was a trigger to increase self-care.

Executive functions (EF) such as self-monitoring, planning, and organizing are known to develop through childhood and adolescence. They are of potential importance for learning and school performance. Earlier research into the relation between EF and school performance did not provide clear results possibly because confounding factors such as educational track, boy-girl differences, and parental education were not taken into account. The present study therefore investigated the relation between executive function tests and school performance in a highly controlled sample of 173 healthy adolescents aged 12–18. Only students in the pre-university educational track were used and the performance of boys was compared to that of girls. Results showed that there was no relation between the report marks obtained and the performance on executive function tests, notably the Sorting Test and the Tower Test of the Delis-Kaplan Executive Functions System (D-KEFS). Likewise, no relation was found between the report marks and the scores on the Behavior Rating Inventory of Executive Function—Self-Report Version (BRIEF-SR) after these were controlled for grade, sex, and level of parental education. The findings indicate that executive functioning as measured with widely used instruments such as the BRIEF-SR does not predict school performance of adolescents in preuniversity education any better than a student's grade, sex, and level of parental education.

Ten eerste wordt nagegaan of volwassenen met ASS beperkt zijn in hun executieve functies Cognitieve Flexibiliteit, Zelfevaluatie, Initiatief nemen, Werkgeheugen en Plannen en Organiseren. Ten tweede wordt onderzocht of beperkingen in het executief functioneren (EF) negatief samenhangen met het gebruik van een probleemgerichte copingstijl (H.1), positief met het gebruik van een emotiegerichte copingstijl (H.2) en positief met gebruik van een passief reactiepatroon (H.3). Daarnaast wordt exploratief onderzocht of leeftijd een modererende invloed heeft op bovengenoemde drie relaties. Volwassenen met een gemiddeld of hoger intelligentieniveau bij wie ASS is vastgesteld hebben een zelfrapportagevragenlijst ingevuld (survey met één meetmoment). Circa 27% van de data is afkomstig uit GGZ-cliëntendossiers, de overige data zijn afkomstig via respondentenwerving (53% non-respons op 182 uitgezette vragenlijsten). Naast enkele biografische gegevens werd gebruik gemaakt van de Brief-A, die beperkingen in het executief functioneren meet en van de Utrechtse Copinglijst (UCL), die het gebruik van zeven copingmechanismen in kaart brengt. Conform H.1 blijken beperkingen in het EF (met name Cognitieve Flexibiliteit) gerelateerd te zijn aan een geringer gebruik van probleemgerichte coping. H.2 wordt niet ondersteund door de bevindingen, aangezien resultaten erop wijzen dat EF geen variantie verklaart in het gebruik van emotiegerichte coping. EF doet dit wel ten aanzien van een passieve reactie, conform H.3. Met name Cognitieve Flexibiliteit en Werkgeheugen spelen hier een betekenisvolle rol. Er is geen significante ondersteuning voor een modererende rol van leeftijd in de drie verbanden.
