El presente estudio se inscribe en el cruce entre dos tópicos de investigación: por un lado, la pedagogía libertaria y, por el otro, la discusión en torno a la identidad docente y su vínculo con lo político. Mediante esta investigación se busca describir la identidad y la percepción acerca de su rol de acompañantes que actualmente trabajan en proyectos de educación libertaria. Para esto se procede a investigar a seis docentes de tres escuelas libertarias existentes en España: La Tribu, Wayra y Tartaruga. El paradigma en que se inscribe esta investigación es fenomenológico, pues lo que se busca es describir la propia percepción de los investigados, y el instrumento que se utilizó para conocerla es la entrevista semiestructurada. Realizar esta investigación permitió conocer distintos aspectos de la identidad de los docentes entrevistados tales como su metodología, sus estrategias de resolución de conflictos, su opinión acerca de las características deseables de un docente, así como la influencia que su posicionamiento político-ideológico y su militancia tienen en su proceder en el aula. Estos resultados se presentan como una contribución al estado del arte, en la medida que develan dimensiones no advertidas por la literatura acerca del rol del docente libertario, así como muestran una forma en que la militancia se conecta con la identidad de un modo en que la literatura no ha abordado en profundidad. ; The present study is part of the cross between two research topics: on the one hand, libertarian pedagogy and, on the other, the discussion around the teaching identity and its link with the political. This research seeks to describe the identity and perception of their role as teachers of those who currently work in libertarian education projects. For this, six teachers from three libertarian schools in Spain are investigated: La Tribu, Wayra and Tartaruga. The paradigm in which this research is inscribed is phenomenological, since what is sought is to describe the own perception of those investigated, and the instrument used to know it is the semi-structured interview. Carrying out this research allowed knowing different aspects of the identity of the teachers interviewed such as their methodology, their conflict resolution strategies, their opinion about the desirable characteristics of a teacher, as well as he influence that their political-ideological position and their militancy have on their actions in the classroom. These results are presented as a contribution to the state of the art, to the extent that they reveal dimensions not noticed by the literature about the role of the libertarian teacher, as well as showing a way in which militancy connects with identity in a way that the literature has not addressed in depth. ; Departamento de Pedagogía ; Departamento de Filosofía (Filosofía, Lógica y Filosofía de la Ciencia .) ; Máster en Investigación Aplicada a la Educación

The National Government implemented an initiative to protect and secure the health of all of the victims of traffic accidents nationwide in Traffic Accident Compulsory Insurance, SOAT, implemented successfully in other countries. Currently hospitals are struggling to invest in managing the logistics involved to obtain the information needed to facilitate the recovery of patient care values covered accident SOAT. The current process, the information entered does not consolidate the different institutions and organizations involved, there are problems, delays and confusion at the time of disbursement of values for different coverages, the insurance companies. This thesis seeks to design a prototype of a Web Management System to document and make online inquiries about the data of those involved in traffic accidents, to provide hospitals, insurance companies and transit agencies better interaction.

The present study reports one of the few cases in which organophosphate (OP) and pyrethroid (PYR) pesticide human exposure is evaluated in family contexts by the analysis of mother/child pair samples. Urinary concentrations of 6 organic metabolites of organophosphates and 2 pyrethroids were measured in mothers and their 7-to 8-year-old children (n = 168) in a general population from the central area of Slovenia. The results were adjusted for specific gravity and creatinine. The most abundant OP metabolite in children was 4-nitrophenol (PNP) (median 0.7 ng/ml) and in mothers (0.45 ng/ml), representing parathion exposure. 3-Phenoxibenzoic acid (3-PBA) (0.26 ng/ml), the general metabolite of pyrethroids, and 3,5,6-trichloro-2-pyridinol (TCPY) (0.16 ng/ml; chlorpyriphos) were the second most abundant compounds in children and mothers, respectively. The geometric mean specific gravity adjusted concentrations of OPs and PYRs were statistically significantly higher in children than in their mothers (between 3% and 24% higher), with the exception of TCPY (26% lower). All OP and PYR metabolites found in higher concentration in children showed significant positive correlations with the metabolite concentrations found in the mothers (p < 0.05 and 0.01), involving the fact that higher maternal concentrations were associated with higher children levels. These differential mother-children distributions and significant correlations were observed for the 2 types of pesticides studied, OPs and PYRs, which have different chemical properties. This agreement is consistent with the incorporation of the pesticides because of the general activities developed in the family context, instead of pesticide-dependent specific inputs. Comparison of the estimated daily intakes with the acceptable daily intakes of all detected metabolites revealed no significant risk of adverse health effects from exposure to these pesticides. © 2019 The Authors ; The authors are grateful to all women who participated in the study, the participating hospital for the data sampling and all the field workers for their enthusiastic efforts.

Urinary metabolites of organophosphate (OP) and pyrethroid (PYR) pesticides and biomarkers of effects were studied in a population (n=40) residing in an important agricultural area of the province of Córdoba (Argentina). Detection frequencies (DF) higher than 85% were observed for the metabolites of pirimiphos (2-diethylamino-6-methylpyrimidin-4-ol –DEAMPY-, median 7.5 μg/g creatinine, DF: 100%), parathion (p-nitrophenol, 0.99 μg/g creatinine, 100%), and chlorpyrifos (3,5,6-trichloro-2-pyridinol, 0.25 μg/g creatinine, 85%). The DEAMPY concentrations doubled the levels found in other studies and were negatively associated with Er-AChE activity, suggesting the appearance of health effects already in environmental exposure levels below established acceptable daily intakes (ADIs). 3-Phenoxybenzoic acid, the metabolite of several PYR pesticides, was also found in all samples. This metabolite was also significantly negatively correlated with Er-AChE, indicating effects of pyrethroid pesticides on the acetylcholine system even at concentrations below the ADI. ; This work was supported by grants from the Agencia Nacional de Promoción Científica y Técnica (FONCyT-PICT2015-1784), Secretaría de Ciencia y Técnica (SECyT, UNC, Res. 411/2018), and Project EDCMET (H2020-HEALTH/0490-825762) funded by the European Union.

Urinary metabolites of organophosphate (OP) and pyrethroid (PYR) pesticides from seven years old children of a birth cohort study (n=199; PHIME cohort of Trieste, Italy) have been measured. Six OP and two PYR metabolites have been investigated, 2-diethylamino-6-methylpyrimidin-4-ol (DEAMPY, pirimiphos metabolite) was the one found at higher concentrations, median 3.4 ng/mL specific gravity adjusted (SG adjusted), followed by 4-nitrophenol (PNP, median 1.4 ng/mL SG adjusted) and 3,5,6-trichloro-2-pyridinol (TCPY, median 0.36 ng/mL SG adjusted), parathion and chlorpyriphos metabolites, respectively. TCPY concentrations were low in comparison to other distributions of OP metabolites in children from other studies. Accordingly, the PHIME cohort showed a distinct OP metabolite distribution with high concentrations of pirimiphos and parathion. Another specific characteristic of this cohort was the high concentration of 3-phenoxybenzoic acid (3-BPA, median 0.36 ng/mL SG adjusted), a general metabolite of PYR pesticides. Evaluation of anthropometric and socio-demographic characteristics of children and families only showed a positive association between family educational level and urinary concentrations of DEAMPY metabolite (p<0.05), which could reflect distinct dietary habits depending on the educational level. Estimated daily intakes were evaluated, all studied metabolites were found within safe levels. © 2019 Elsevier Inc. ; Authors are grateful to the women who participated in our study as well as the people who helped in the recruitment in the different countries.
