    Youth between the ages of 18-21 leaving the foster care system typically face poor outcomes when transitioning into adulthood. This “aging-out” population encounters many challenges, including lack of adult support, financial instability, poor educational/vocational opportunities and outcomes, and lack of safe and affordable housing. Older youth exiting the foster care system are more likely to experience unplanned pregnancy, unemployment, criminal justice involvement and substance use. Additionally, youth who have been in foster care are at increased risk for behavioral and mental health difficulties after leaving foster care (Courtney el al., 2007; Stein, 2006; Freundlich & Avery, 2008). Yet, despite the preponderance of evidence for poor outcomes and the seemingly insurmountable challenges faced by this population, a number of youth leave the foster care system and are able to lead satisfying, productive lives. This qualitative study used intensive interviews to explore the trajectory of a small number of youth who have transitioned out of foster care, outlining the social, economic and psychological barriers they faced while also charting the attitudes, behaviors and experiences that allowed them to successfully exit the foster care system and move toward productive adult lives. Results of the study suggest that successes among this population are hard-won and tenuous. Ultimately the youth in this study were able to overcome obstacles and navigate the transition to adulthood by tapping both internal strengths and external resources, including the ability to reconcile and move beyond disappointments, connect with others, and take advantage of available sources of support

    UVA photoactivation of harmol enhances its antifungal activity against the phytopathogens Penicillium digitatum and Botrytis cinerea

    Phytopathogenic fungi responsible for post-harvest diseases on fruit and vegetables cause important economic losses. We have previously reported that harmol (1-methyl-9H-pyrido[3,4-b]indol-7-ol) is active against the causal agents of green and gray molds Penicillium digitatum and Botrytis cinerea, respectively. Here, antifungal activity of harmol was characterized in terms of pH dependency and conidial targets; also photodynamic effects of UVA irradiation on the antimicrobial action were evaluated. Harmol was able to inhibit the growth of both post-harvest fungal disease agents only in acidic conditions (pH 5), when it was found in its protonated form. Conidia treated with harmol exhibited membrane integrity loss, cell wall disruption, and cytoplasm disorganization. All these deleterious effects were more evident for B. cinerea in comparison to P. digitatum. When conidial suspensions were irradiated with UVA in the presence of harmol, antimicrobial activity against both pathogens was enhanced, compared to non-irradiated conditions. B. cinerea exhibited a high intracellular production of reactive oxygen species (ROS) when was incubated with harmol in irradiated and non-irradiated treatments. P. digitatum showed a significant increase in ROS accumulation only when treated with photoexcited harmol. The present work contributes to unravel the antifungal activity of harmol and its photoexcited counterpart against phytopathogenic conidia, focusing on ROS accumulation which could account for damage on different cellular targets.Fil: Olmedo, Gabriela María.

    Schools as Laboratories: Science, Children's Bodies, and School Reformers in the Making of Modern Argentina (1880-1930)

    Get PDF
    This dissertation examines the influence of scientific ideas in the school to illuminate teachers’ participation in the production of scientific knowledge about pedagogy and childhood. I interrogate how scientific theories circulating transnationally —including positivism, Darwinism, neo-Lamarckianism, and eugenics—, impacted pedagogical theory and practice. I contribute to the historiographies on race and gender in Latin America by conceptualizing the schools as a laboratory, a site for the circulation and production of scientific knowledge. Between 1880 and 1930, Argentina experienced cultural, political, and economic transformations. Argentine elites promoted their nation’s insertion into the world economy through industrialization, urbanization, and European immigration. Drawing on scientific ideas that provided a language to diagnose and propose solutions to social problems, the government founded normal schools, secondary education institutions to train teachers. In 1884, the Congress passed a law that universalized primary education. Primary and normal schools became the means to incorporate children into the nation and the site where thousands of first-generation students —mostly women— continued their studies with the help of a state run system of national and provincial fellowships. I argue that in school laboratories teachers contributed to reproducing the positivist and racist ideologies that disciplined children while, at the same time, teaching prompted women to participate in science. Women became producers of knowledge within a local and transnational network that expanded beyond the classroom and connected their practice with magazines, congresses, and scientific journals. By observing children’s bodies and experimenting with pedagogical methods, teachers advanced pedagogy as a science and developed studies on children’s intelligence. Drawing on their teaching experiences and in scientific discourses circulating transnationally, many teachers used their position to challenge what they considered as disciplinary and authoritarian practices and organized to democratize the school. School reformers experimented with teaching methods, enacting alternative ways of schooling that centered on children’s freedom of movement and expression. By looking at the links between science and teaching, I contribute to highlighting the historical connections between the emergence of universal schooling in Latin America, the rise of eugenic thought, and the emergence of women’s participation in science and politics

    Semiochemical exploitation of host-associated cues by seven Melittobia parasitoid species: Behavioral and phylogenetic implications

    Get PDF
    Chemical compounds (infochemicals or semiochemicals) play an important role both in intra-specific and inter-specific communication. For example, chemical cues appear to play a key role in the host selection process adopted by insect parasitoids. In recent years significant advances have been made in order to understand the chemical ecology of insect parasitoids. However, little information is available about the evolution of semiochemical use in the host location process of insect parasitoids. Here we investigated the strategy adopted by seven closely related parasitoid species in the genus Melittobia when foraging for four different suitable hosts. By using an integrated approach that combined olfactometer bioassays and phylogenetic investigations, we found that: (1) exploitation of host-derived semiochemicals is widespread in the Melittobia genus; (2) there is specificity of attraction toward the different host species tested; in particular, the early-branching species in the Melittobia genus are attracted to odors associated with leaf cutting bees (Megachile rotundata) whereas the most-diverged species are attracted to odors associated with solitary mud dauber wasps (Trypoxyilon politum). Regardless of the phylogenetic relationships, no Melittobia species exhibited attraction toward odors of factitious laboratory hosts (i.e., the flesh fly Sarcophaga bullata). Interestingly, five Melittobia species are also attracted by odors associated with honeybees hosts which indicate that these parasitoids could be potential pests of honeybees. Our study shed light on the host location within the Melittobia genus and represents a first attempt to understand semiochemical use in an evolutionary perspective in the context of parasitoids' foraging behavior

    Temaet for denne oppgaven er utenriksjournalistikk og handler om hvordan organisasjonens og redaksjonelle prioriteringer kan påvirke journalistikken fra Sør-Amerika. Denne oppgaven bygger på et kvalitativt metode, der jeg sammenligne svarene jeg har fått av tre ulike utenriksredaktører fra NRK, Aftenposten og Klassekampen. Problemstillingen denne oppgaven besvarer blir derfor «hvordan påvirker NRK, Aftenposten og Klassekampens organisasjon og redaksjonelle prioriteringer journalistikken som kommer fra Sør-Amerika?». De viktigste funnene denne oppgaven viser at det finnes ulike prioriteringer som påvirke journalistikken fra Sør-Amerika. Prioriteringer som går ut på valg av nyhetskriterier, begrensede ressurser som antall korrespondenter, økonomi og plass på papirutgavene påvirker også hva som blir publisert. I tillegg til geografisk avstand som spiller en avgjørende faktor i journalistikken fra det søramerikanske kontinentet.The topic of this assignment is foreign journalism and is about how the organisation's and editorial priorities can affect journalism from South America. This thesis is based on a qualitative method, where I compare the answers I have received from three different foreign editors from NRK, Aftenposten and Klassekampen. The problem this thesis answers is therefore "How do NRK, Aftenposten and Klassekampen's organization and editorial priorities affect the journalism that comes from South America?". The most important findings of this thesis show that there are different priorities that influence journalism from South America. Priorities based on the choice of news criteria, limited resources such as the number of correspondents, finances and space on the paper editions also affect what is published. In addition to geographical distance, which plays a decisive factor in journalism from the South American continent

    Estudio experimental sobre el comportamiento térmico de un nuevo tipo de techo-estanque para el enfriamiento pasivo en clima húmedo

    Get PDF
    En este trabajo, una nueva tipología de techo-estanque metálico, basado en el enfriamiento evaporativo indirecto, que incluye masa térmica confinada, se evalúa experimentalmente. Cinco sistemas de enfriamiento pasivo se han estudiado con este dispositivo experimental. Se analizan sus temperaturas características con el propósito de determinar en cada caso, su potencial de enfriamiento, así como, la influencia de la masa térmica en su comportamiento térmico. Entre las técnicas de enfriamiento pasivo aplicadas se encuentran el enfriamiento evaporativo indirecto (EEI) y el enfriamiento radiativo nocturno (ER). El sistema donde se combina masa térmica con enfriamiento evaporativo indirecto en el dispositivo experimental presenta una elevada eficiencia de enfriamiento; su valor aumenta a medida que las condiciones son más extremas. Un potencial de enfriamiento aun mayor se consigue al agregar al sistema anterior enfriamiento radiativo

    El objetivo del trabajo fue analizar el riesgo sanitario no carcinogenético a partir de ciertas sustancias (inorgánicas, fenólicas, metales pesados y pesticidas) presentes en aguas superficiales y subterráneas de la ciudad de Tres Arroyos. El análisis se realizó utilizando el modelo básico de análisis de riesgo sanitario probabilístico de USEPA considerando tres estratos de edades infantiles (5, 10 y 15 años). Se integraron escenarios de tipo residencial con recreativo, sobre la base de la exposición por la ingesta y por el contacto dérmico con el agua. En los tres estratos de edad, los resultados indican que los valores del riesgo integrado (riesgo residencial + riesgo recreativo) fueron significativos y decrecientes con relación a la edad, siendo el arsénico el principal contribuyente a través de la vía de ingesta consuntiva del escenario residencial.The objective of this work was to analyze the non-carcinogenic health risk from certain substances (inorganic, phenolic, heavy metals and pesticides) in surface waters and groundwater in the town of Tres Arroyos. The analysis was performed using the basic model of health risk analysis considering probabilistic USEPA for children of three age groups (5, 10 and 15). Residential and recreational type scenarios were integrated, based on exposure through ingestion and dermal contact with water. In all three age strata, the results indicate that the values of the integrated risk (residential risk + recreational risk) were significant and decreasing with respect to age, being arsenic the largest contributor through the residential ingestion pathway.O objetivo do trabalho foi analisar o risco sanitário não-carcinogênico a partir de determinadas substâncias (inorgânicas, fenólicas, metais pesados e pesticidas) presentes em águas superficiais e subterrâneas da cidade de Tres Arroyos.
