Memory for Spatial Locations: An Eye-Tracking Study

Working memory is the ability to store information while also using it to process cognitive tasks. Working memory has very limited capacity. Ropeter and Pauen (2013) found that that infants who had higher working memory also had higher habituation and dishabituation responses compared to infants who had lower scores on working memory. Visuo-spatial tasks are very different from one another; some give greater spatial cues while others might be more complex and may require different spatial working memory capacities. Studies have found sex differences in performance on spatial tasks in subjects as young as four months old (Moore & Johnson, 2008; Quinn & Liben 2008). The present study involved familiarizing infants between 10 months and 24-months with a target object based on Tzuriel and Egozi’s (2010). Stimuli consisted of a house oriented at one of three possible angles, with rattles in 1, 2, or 3 of the windows. In the test trial, infants were shown the same target object during the familiarization phase along with the mirror image of the target object. Our study examines a set of variables thought to affect 13- and 20- month-olds’ ability to represent and remember spatial locations of objects, including the number of objects and degree of rotation of the target object. Our results revealed no significant sex difference in preference between familiar and novel images after familiarization, even when controlling for age. In addition, there were no significant moderating effects of angle of rotation or number of objects presented. Our results suggest that the sex differences observed in mental rotation are not present in infants as early as 20 months. This supports the argument that boys and girls have differential spatial experiences, which may explain sex differences in mental rotation in later years

As juventudes na Educação de Jovens e Adultos

TCC(graduação) - Universidade Federal de Santa Catarina. Centro de Ciências da Educação. Pedagogia.O presente trabalho de conclusão de curso consiste na pesquisa sobre a compreensão dos jovens que cada vez mais cedo procuram a Educação de Jovens eAdultos. Procura compreender comoestão organizadas as práticas pedagógicas na EJA, em vista à juvenilização. Reconhecer algumas especificidades da EJA, perpassando por suas características, opiniões dos alunos e pela formação docente com base nos depoimentos de estudantes da EJA de pesquisas realizadas sobre o tema. Metodologicamente em função dos objetivos da pesquisa realiza-se uma pesquisa de abordagem qualitativa de caráter bibliográfica. Em seu desenvolvimento o trabalho tem como objetivo contextualizar a educação de Jovens e Adultos, retratando historicamente seu surgimento no Brasil, identificar os conceitos de jovens e juventudes que perpassam a educação de jovens e adultos. Com a intenção de aprofundar as considerações trouxe diálogos com teóricos. Os teóricos que se apresentaram mais recorrentes para essa pesquisa foram: Paiva (1983), Frigotto (1993); Haddad e Di Pierro (2000) apresentarei um histórico da constituição da Educação de Jovens e Adultos no Brasil. Teórico como: Arroyo (2006), Aquino (2009), Durand (2004), Furini, Durand e Santos (2011), Dayrell (2003), e Oliveira (2001), irão contribuir para o entendimento sobre a questão da juventude e as suas singularidades, como questão social, seus conceitos de pluralidade e diversidade, e abordando a complexidade das juventudes. Por fim, com relação à metodologia de trabalho pedagógico desenvolvido pela proposta da pesquisa como princípio educativo me fundamentei a partir de Souto (2009) trazendo quais práticaspedagógicas estão sendo utilizadas no processo de ensino e aprendizagem para atender igualmente jovens e adultos que dividem o mesmo espaço de sala de aula

Early warning systems for economic crises in South Africa.

This paper develops a series of Early Warning System models for debt crises. This paper uses a Debt Pressure index to define crisis periods and then demonstrates how one can go about trying to forecast these periods using Logit and Markov-switching Models. An alternative approach, whereby ordinary least squares (OLS) is used to create Early Warning System models, is introduced. A graphical analysis is also conducted. Three useful Early Warning System models emerge from this study

Situación actual del programa Chile crece contigo en la séptima región del Maule: descripción de las modalidades de atención, los equipos de trabajo y la caracterización del desarrollo psicomotor de los niños y niñas

92 p.Introducción: El desarrollo humano comienza desde la concepción y es fundamental su adecuada estimulación a lo largo de todo el ciclo vital (Oates, 2012). La implementación de programas para el desarrollo infantil temprano se ha instaurado en muchos países (Engle, 2007), y en Chile se encuentra el programa Chile Crece Contigo, donde participan actores sociales que, junto a diversos factores, influyen directa o indirectamente en el desarrollo de los niños. A partir de esto, nace la inquietud de conocer cuál es la situación actual de este programa en la región del Maule, las modalidades de atención, quiénes lo componen y la categorización del desarrollo psicomotor de los niños y niñas de nuestra región. Objetivo: Describir las características de los equipos y caracterización del desarrollo psicomotor de los niños y niñas en el programa Chile Crece Contigo en la VII región del Maule. Metodología: Estudio descriptivo del análisis de datos de las modalidades de atención, profesionales trabajando en ellas, número de niños atendidos y su categorización según EEDP de las planillas MADI y REM A03 de la región del Maule. Resultados: 90% de las salas en la región corresponde a SE y 10% a SI. 92% está a cargo de Educadoras de Párvulo. El kinesiólogo está presente en el 25% de las salas. 91% de los niños/as están en SE y 9% en SI. Respecto a su categorización, 90% del total de niños/as tiene un desarrollo psicomotor normal, 5% normal con rezago, 4% riesgo, y 1% retraso. Conclusión: En el programa Chile Crece Contigo existen dos modalidades de atención: las SE y SI. La cantidad de salas SI es escasa para la región, tomando en consideración el índice de ruralidad de ésta. Existe un bajo porcentaje de kinesiólogos que participan en salas del programa Chile Crece Contigo de la VII región del Maule. La realidad regional de los niños con alteración en el desarrollo psicomotor tiene un comportamiento similar a la de la realidad nacional. En el rango de 18 a 47 meses se encuentra el mayor porcentaje de niños con problemas en el desarrollo psicomotor.Palabras clave: Brain plasticity, neuronal plasticity, early child development, early child stimulation, Chile Crece Contig

Insulin gene polymorphisms in type I diabetes, Addison's disease and the polyglandular autoimmune syndrome type II

Background: Polymorphisms within the insulin gene can influence insulin expression in the pancreas and especially in the thymus, where self-antigens are processed, shaping the T cell repertoire into selftolerance, a process that protects from ß-cell autoimmunity. Methods: We investigated the role of the -2221Msp(C/T) and -23HphI(A/T) polymorphisms within the insulin gene in patients with a monoglandular autoimmune endocrine disease [patients with isolated type 1 diabetes (T1D, n = 317), Addison´s disease (AD, n = 107) or Hashimoto´s thyroiditis (HT, n = 61)], those with a polyglandular autoimmune syndrome type II (combination of T1D and/or AD with HT or GD, n = 62) as well as in healthy controls (HC, n = 275). Results: T1D patients carried significantly more often the homozygous genotype "CC" -2221Msp(C/T) and "AA" -23HphI(A/T) polymorphisms than the HC (78.5% vs. 66.2%, p = 0.0027 and 75.4% vs. 52.4%, p = 3.7 × 10-8, respectively). The distribution of insulin gene polymorphisms did not show significant differences between patients with AD, HT, or APS-II and HC. Conclusion: We demonstrate that the allele "C" of the -2221Msp(C/T) and "A" -23HphI(A/T) insulin gene polymorphisms confer susceptibility to T1D but not to isolated AD, HT or as a part of the APS-II

Interleukin Gene Expression in Mouse Preimplantation Development

Control of growth and differentiation during mammalian embryogenesis is regulated by growth factors from embryonic and/or maternal sources. Cytokines are polypeptide growth factors that are released by a variety of activated immune and nonimmune cells. To identify novel members of the cytokine family that could be involved in the growth and differentiation of the preimplantation embryo, we studied the expression pattern of several genes encoding cytokines and their receptors during mouse preimplantation development in vitro We found that poly(A)+ mRNAs for IL-1, IL-3, IL-6, IL-7, and TNFα are differentially expressed at several stages of mouse preimplantation development, including unfertilized oocytes. Immunostaining of preimplantation embryos using monoclonal antibodies specific for several cytokines and their receptors revealed that at least some of these mRNAs are translated into mature proteins during preimplantation development (IL-1, IL-6, and TNFα). Positive staining for IL-1 and IL-6 receptors was also detected at these stages of development. The controlled expression of these “inflammatory-type” cytokines and their receptors suggests a role for these growth factors during the early phases of mouse ontogeny
