O comportamento pró-social de crianças com sintomatologia do transtorno da conduta

Pro-social behaviors are seen regularly throughout our daily lives, as we often witness people giving alms, helping a neighbor move, donating blood, or taking care of a friend's children, among others. From an evolutionary perspective, such behaviors occur because they have a high adaptive value to our species, precisely due to our high degree of dependence on group living for survival. Probably, for this same reason, since children have shown a preference for prosocial behaviors over antisocial behaviors, this preference becomes more visible as we grow. However, children with symptoms of conduct disorder show a pattern of aggressive, impulsive and more selfish behaviors than children without such symptoms. Furthermore, these children also experience environments in which antisocial behaviors are more frequent and intense compared to the general population. Priming experiments are one way of measuring the influence of simple environmental cues on our behavior. For example, driving faster when listening to music, religious people help more on religious elements, like the bible, and children are more cooperative after playing games of an educational nature. Thus, the objectives of the current study were to: evaluate whether there is any difference in generosity, through sharing behavior, among children with and without symptoms of conduct disorder; analyze the influence of prosocial priming on sharing behavior on children with and without symptoms of conduct disorder; and finally, analyze from an evolutionary perspective, the reasons given by children with and without symptoms of conduct disorder for sharing or not sharing with their best friend in a classroom environment. To address this question, the teachers of these children were asked to respond to an inventory that was designed to signal the presence or absence of symptoms of conduct disorder. Children identified as having or not having symptoms of conduct disorder could then undergo an experimental (with priming) or control (no priming) condition. Under the experimental condition, the children were asked to watch two short videos showing scenes of helping and sharing among peers, to perform a distraction activity, and finally to chose two of four different materials presented by the researcher and decide how much of these two materials they would like to share with their best friend in the classroom. Then the children were asked about their reasons for sharing or not sharing. Children subjected to the control condition performed the same activities as in the xi experimental condition, but did not watch the video first. The results showed a notable difference in the effect of priming in accordance with the child's stage of development; a difference in the amount of material donated to a best friend by children with and without symptoms of conduct disorder, and a change in this observed difference with the influence of pro-social priming; and finally, a convergence in the thinking of children regarding their reasons for sharing with evolutionary theory. The results of this study also indicate the importance of individual factors, developmental stage, environmental and evolutionary conditions in the pro-social behavior of children with and without symptoms of conduct disorder.

Vernaculares: a casa de fazenda seridoense do século XIX como exemplo de adaptação ao clima semiárido

The farm’s rural dwellings of creation from the Seridó Potiguar microregion, built in the nineteenth century, became a reference by its vernacular character, i.e. these buildings, besides having recognized relevance to the identity of the region, they are adapted to the conditions of the place in many aspects (economic, cultural, construction, physical, et.) and consist in protective spaces in relation to hostile characteristics of Seridó’s climate. Considering the above premise, the following question arises: What characteristics of the nineteenth century Seridó Potiguar’s cattle farms are crucial for them to be a protective space in relation to the semiarid climate? In order to answer the question, this research aim to identify which particularities of the Seridó’s farmhouses that contribute to adaptability in these buildings to semiarid climate, as protection environments; and contribute to the stock valuation of the architectural heritage concerned. Therefore, procedures were adopted divided into two stages. Were first identified the recurring characteristics in the studied buildings, through typological study performed from existing inventories (DINIZ, 2008; FEIJÓ, 2002; IPHAN, 2012). To define the type it worked up with the concept that merges Durand’s analytical typology that identifies the similarities and differences to classify buildings, having the character of historical survey and architectural documentation, with the definition proposed by Argan (1963) that the type is not defined a priory, but the deduction from a number of illustrative cases which have formal and functional similarity with each other. Then worked up in a sample of five different types with each other, defined by the possibility of access to the interior of the houses, proximity to other copies, good state of conservation and preservation. The contemplated farms were: Pitombeiras, Agenus e Garrotes in Acari’s town, and the municipality of Caicó, Palma and Penedo. The second stage consists of the architectural survey, photographic record, digital three-dimensional modeling (aiming to expand the existing documentation and registration) and thermal monitoring over approximately a representative day in five farmhouses, relating the thermal performance of the houses with their individual characteristics. The selected variables for analysis monitoring are based on the thermal comfort adaptive model (SPAGNOLO and DE DEAR, 2003 apud NEGREIROS, 2010). The characteristics of the houses were analyzed as meeting the passive thermal conditioning strategies recommended by NBR 15220 (ABNT, 2005), for the bioclimatic zone 7 where the municipalities of Caicó and Acari are located. The house’s analysis of the operating temperatures revealed that 90% of the times of day the environments are within the comfort range. The farmhouses, which had a higher degree of compliance with recommended bioclimatic strategies, had the best thermal performance. In environments (usually the kitchen and rooms with low ceiling heights, exposed to west radiation) which still had discomfort hours, the thermal comfort can be reached with air movement approximately 1,0 m/s.

Mineralogy, mineral chemistry, and genesis of precious metal-bearing volcanogenic massive sulfide deposits in the Newfoundland Appalachians, Canada: the Ming deposit as example

The Ming deposit, Newfoundland Appalachians, is a metamorphosed (upper greenschist to lower amphibolite facies), Cambro-Ordovician, bimodalmafic volcanogenic massive sulfide (VMS) deposit that consists of several, spatially-associated, elongated orebodies composed of stratabound semimassive to massive sulfides and/or discordant sulfide stringers in a rhyodacitic footwall. Copper is the main commodity; however, the deposit contains precious metal-bearing zones with elevated Au grades. In this study, field observations, microscopy, and micro-analytical tools including electron microprobe, laser ablation inductively coupled plasma mass spectrometry, and secondary ion mass spectrometry were used to constrain the relative timing of precious metal emplacement, the physico-chemical conditions of hydrothermal fluid precipitation, and the sources of sulfur, precious metals, semi-metals and metals. The ore mineral assemblage is complex and indicates an intermediate sulfidation state. Pyrite and chalcopyrite are the dominant ore minerals with minor sphalerite and pyrrhotite, and trace galena, arsenopyrite and cubanite. Additional trace phases include tellurides, NiSb phases, sulfosalts, electrum, AgHg±Au alloys, and oxides. Silver phases and precious metals occur predominantly in semi-massive and massive sulfides as free grains, and as grains spatially associated with arsenopyrite and/or sulfosalts. Precious metal phases occurring between recrystallized pyrite and within cataclastic pyrite are rare. Hence, the complex ore assemblage and textures strongly suggest syngenetic precious metal emplacement, whereas metamorphism and deformation only internally and locally remobilized precious metal phases. The ore assemblage formed from reduced, acidic hydrothermal fluids over a range of temperatures (≈350 to below 260ºC). The abundance of telluride and Ag-bearing tetrahedrite, however, varies strongly between the different orebodies indicating variable ƒTe₂, ƒSe₂, mBi, and mSb within the hydrothermal fluids. The variations in the concentrations of semi-metals and metals (As, Bi, Hg, Sb, Se, Te), as well as Au and Ag, were due to variations in temperature but also to a likely contribution of magmatic fluids into the VMS hydrothermal system from presumably different geothermal reservoirs. Sulfur isotope studies indicate at least two sulfur sources: sulfur from thermochemically-reduced seawater sulfate and igneous sulfur. The source of igneous sulfur is the igneous footwall, direct magmatic fluid/volatiles, or both. Upper greenschist to lower amphibolite metamorphic conditions and deformation had no significant effect on the sulfur isotope composition of the sulfides at the Ming deposit.

Physical oceanography, sea-bed photographs and videos of benthos from the Weddell Sea taken with remote operated vehicle CHEROKEE during POLARSTERN cruise ANT-XXIII/8

The marine ecosystem on the eastern shelf of the Antarctic Peninsula was surveyed 5 and 12 years after the climate-induced collapse of the Larsen A and B ice shelves. An impoverished benthic fauna was discovered, that included deep-sea species presumed to be remnants from ice-covered conditions. The current structure of various ecosystem components appears to result from extremely different response rates to the change from an oligotrophic sub-ice-shelf ecosystem to a productive shelf ecosystem. Meiobenthic communities remained impoverished only inside the embayments. On local scales, macro- and mega-epibenthic diversity was generally low, with pioneer species and typical Antarctic megabenthic shelf species interspersed. Antarctic Minke whales and seals utilised the Larsen A/B area to feed on presumably newly established krill and pelagic fish biomass. Ecosystem impacts also extended well beyond the zone of ice-shelf collapse, with areas of high benthic disturbance resulting from scour by icebergs discharged from the Larsen embayments.

A noção de relação na teoria linguística de Ferdinand de Saussure

Our work aims at investigating the notion of relation in Ferdinand de Saussure’s linguistic reflections. As we observe his theoretical production, we see this notion was amply worked in the elaboration of other concepts of his, for example, language, signe, value, arbitrariness, among others. However, beyond the capacity of the notion of relation to produce other concepts, the way it was conceived and the theoretical space it was placed allowed Saussure to break through the essentially historical-comparative studies of the epoch, what made a new way of thinking language to have its starting point. Taking it into account, firstly, by reading the work of Herman Paul, the one who represents the neogrammarians in our text, we examine in which way Saussure is distant from his contemporary linguistics when he distinguishes the linguistic relations and give them a new status in his investigation. Secondly, we study how the notion of relation has it own place in Saussure’s theoretical process of thinking the fundamentals which later would be considered the milestone for Modern Linguistics. For that, we analyse one of his manuscripts, Notes pour un livre sur la linguistique générale, and the Course in General Linguistics. The first is composed by sketches which would become a book, as Saussure promised in a letter to Meillet; and the latter contains the principals for the science of Linguistics. So we aim at researching how the notion of relation is treated in this corpus in order to see the way it is conceived both in the particular production of a manuscript written by Saussure itself and the book which was published and considered the turning point for Linguistics.

Has your work worked you too hard? Physically demanding work and disability in a sample of the older Irish population

There is a heightened need for the practitioner to be alert to the determinants of functional limitations and disabilities owing to the ageing workforce. This study investigated the association between work type and disability in older age in both the paid and the previously unexplored, unpaid worker (household labour).Data on demographic factors, physical measurements, work history and functional status were collected on three hundred and fifty seven 57-80-year-olds. Past or present work was identified as either physically demanding or not. Functional limitations and activities of daily living (ADL) disabilities were assessed using validated scales. Logistic regression was used to examine the relationship between the dependent variables and work type (physically demanding work or not physically demanding work).Over half of the sample reported doing physically demanding work. 20 % had complete function (n = 67), 65 % (n = 223) functional limitations and 15 % (n = 53) ADL disability. Physically demanding work was associated with functional limitations [OR 2.52 (1.41, 4.51), p = 0.01] and ADL disability [OR 2.10 (1.06, 4.17), p = 0.03] after adjustment for a measure of obesity and gender. When gender stratified, looking only at females, physically demanding work was associated with ADL disability [OR 2.79 (1.10, 7.07), p = 0.03] adjusted for a measure of obesity and household labour. Physically demanding work was related to functional limitations and ADL disability in older age. This is valuable information to inform practitioners in the treatment of older people with functional limitations and disabilities and in guiding interventions in the prevention of work related disability.

The Diary of Mary McKeon, an Irish American Domestic Servant in Nineteenth Century America

What did young, single, unaccompanied Irish women experience when immigrating to the United States in the late nineteenth century? In this final project, I will explore primary and secondary sources that address their experiences, focusing on a diary written in 1883 by a young Irish domestic servant working in New Haven, Connecticut. Mary McKeon, a sixteen-year-old girl from County Leitrim, Ireland, recorded her experiences as a domestic servant for two different families, as well as her own personal thoughts. Mary wrote down her personal experiences, providing a glimpse of what her life was like both inside and outside of her employer’s home. Though much of my research will show that many young women like Mary would be subjected to prejudice and discrimination due to their lack of understanding middle-class American values, which would give rise to the “Bridget” stereotype of a brutish, ill-mannered and incompetent domestic servant, not all Irish women experienced that discrimination and prejudice. Mary is one example of a domestic servant that was treated kindly by her employers and her story documents a more positive and supportive environment for this newly arrived young, single immigrant. Her diary also reveals her to be a young woman who worked to improve her language skills and her situation. And, through her diary, we get a glimpse of her strategies for ensuring an active social life, including access to courtship and marriage. By analyzing Mary’s diary and sharing my results in this final project, I hope to provide a more comprehensive view into the lives of these young women.

"Macanas", "tragedias" y "dramas" : Los jueces y su presentación del pasado de terrorismo de Estado en el Juicio por la Verdad de Bahía Blanca, Argentina

El trabajo que aquí se presenta tiene como objetivo indagar en las diferentes manifestaciones sobre el pasado reciente de terrorismo de Estado realizadas por los jueces durante las audiencias de uno de los denominados "Juicios por la Verdad", que se realizó en la ciudad de Bahía Blanca, Argentina entre 1999 y 2000. Se trabajó con una metodología de análisis cualitativo y se utilizaron distintas fuentes de información tales como entrevistas a jueces y abogados de organizaciones de derechos humanos y la totalidad de los videos de las audiencias del Juicio por la Verdad de Bahía Blanca. Como resultado se establece la manera en que estos profesionales del derecho interpretaron el terrorismo de Estado confrontando la posición adoptada por los militares de no brindar información y de reivindicar la "guerra antisubversiva", deslindando a la vez las distintas responsabilidades entre los miembros de las Fuerzas Armadas.
