Adolescents Prefer More Immediate Rewards When in the Presence of their Peers
Adolescents take more risks in the presence of their peers, but the mechanism through which peer presence affects risky decision-making is unknown. We propose that the presence of peers increases the salience of the immediate rewards of a risky choice. The current study examined the effect of peer presence on reward sensitivity in a sample of 100 late adolescents ages 18 through 20 (M=18.5) using a delay discounting task, which assesses an individual\u27s preference for immediate versus delayed rewards. Participants were randomly assigned to complete the task alone or with 2 same-age, same-sex peers observing. Consistent with our prediction, adolescents demonstrated a greater preference for immediate rewards when with their peers than when alone. Heightened risk taking by adolescents in the company of their friends may be due in part to the effect that being with one\u27s peers has on reward sensitivity

Concept Acquisition of Rotational Dynamics by Interactive Demonstration and Free-Body Diagram
The concepts of force and motion are essential material in physics. However, students experience many difficulties in the concept of force in rotational dynamics. This research was conducted to measure students' concept acquisition of the rotational dynamics through Interactive Demonstration assisted by Free-body diagram. The mixed research method was chosen through the use of test instruments in the forms of 10 multiple-choice with open ended questions. The subjects of the research were 35 students XI IPA Senior High School 2 Sungai Penuh-Indonesia. Students' concept acquisition was measured before and after the intervention to be analyzed quantitatively. The obtained N-gain score was 0.47, and it showed that there was a moderate improvement in students' concept acquisition, while the effect size value was 1.82 showing that the intervention strongly affected students' concept aquisition. The data were also supported by the results of the qualitative analysis of the students' answers and worksheets given during the intervention process
Extended X-ray emission in the IC 2497 - Hanny's Voorwerp system: energy injection in the gas around a fading AGN
We present deep Chandra X-ray observations of the core of IC 2497, the galaxy
associated with Hanny's Voorwerp and hosting a fading AGN. We find extended
soft X-ray emission from hot gas around the low intrinsic luminosity
(unobscured) AGN ( erg s). The
temperature structure in the hot gas suggests the presence of a bubble or
cavity around the fading AGN (\mbox{E_{\rm bub}} \sim 10^{54} - 10^{55}
erg). A possible scenario is that this bubble is inflated by the fading AGN,
which after changing accretion state is now in a kinetic mode. Other
possibilities are that the bubble has been inflated by the past luminous quasar
( erg s), or that the temperature gradient is
an indication of a shock front from a superwind driven by the AGN. We discuss
the possible scenarios and the implications for the AGN-host galaxy
interaction, as well as an analogy between AGN and X-ray binaries lifecycles.
We conclude that the AGN could inject mechanical energy into the host galaxy at
the end of its lifecycle, and thus provide a source for mechanical feedback, in
a similar way as observed for X-ray binaries.Comment: 9 pages, 5 figures, accepted for publication in MNRA

Influ?ncia de Azteca chartifex (formicidae) na microbiota foliar de Byrsonima sericea.
Programa de P?s-Gradua??o em Ecologia de Biomas Tropicais. Departamento de Biodiversidade, Evolu??o e Meio Ambiente, Instituto de Ci?ncias Exatas e Biol?gicas, Universidade Federal de Ouro Preto.A intera??o entre formigas e microrganismos na superf?cie foliar de plantas hospedeiras ? um aspecto negligenciado da ecologia. H? evid?ncias de que a elevada densidade de formigas em um dado habitat foliar pode afetar substancialmente a microbiota, e a rela??o desta com a planta. A quest?o fundamental deste trabalho ? determinar, ainda que de forma preliminar, at? que ponto a microbiota associada a formigas dominantes e abundantes no dossel florestal poderia atuar na inibi??o de grupos microbianos invasivos e potencialmente entomopat?genos. Para tal, foi verificada a influ?ncia das intera??es entre a formiga Azteca chartifex, plantas da esp?cie Byrsonima sericea e bact?rias Gram-positivas e Gram-negativas dos corpos das oper?rias e da superf?cie das folhas. Um ensaio do efeito inibit?rio das pr?prias bact?rias e dos compostos extra?dos de A. chartifex sobre Xanthomonas citri subsp. Citri (XAC 306), Staphyloccocus aureus e S. epidermidis foi realizado. Em acr?scimo, foi verificado o efeito inibit?rio direto de bact?rias mutual?sticas associadas ao exoesqueleto das formigas contra bact?rias das superf?cies foliares de B. sericea. Finalmente, foi avaliado se as bact?rias mutual?sticas com as formigas e com maior potencial inibit?rio seriam Gram-negativas, devido ?s vantagens adaptativas das duas membranas deste tipo de bact?ria para ocupa??o de ambientes extremos. Verificamos que os compostos extra?dos de A. chartifex n?o tiveram efeito inibit?rio contra S. aureus e X. citri subsp. Citri. Ao contr?rio, os tratamentos contendo o extrato das formigas obtiveram maiores taxas de crescimento destas bact?rias. Por outro lado, foi encontrado que bact?rias associadas ? A. chartifex tiveram maior taxa de crescimento sobre bact?rias Gram-positivas associadas ?s folhas de B. sericeae que n?o possuem intera??o com essas formigas, portanto sugerindo potencial de inibi??o. Tamb?m foi detectado que a maior taxa de crescimento foi de bact?rias de formigas provenientes do ninho matriz em rela??o aos ninhos sat?lites. Os filos mais representativos dos isolados das formigas foram Proteobacteria, Firmicutes e Actinobacteria. Houve maior porcentagem de Gram-negativas nos tr?s grupos de amostras. Portanto, as formigas carregam bact?rias capazes de inibir microrganismos ex?genos ? microbiota associada ? A. chartifex, bact?rias Gram-negativas seriam mais competitivas que Gram-positivas, e h? um maior investimento em defesa dentro de col?nias onde h? maior densidade de indiv?duos, que seleciona isolados mais agressivas na inibi??o de bact?rias ex?genas ao sistema
Characterization of Carotenoid Pigments From Bacterial Symbionts of Seagrass Thalassia Hemprichii
Carotenoids are pigments that can be used in various applications including cosmetics and precursor ofvitamins A. Carotenoids are mostly found in higher plant leaves, fruit, and bacteria. Marine bacteriaassociated with seagrass Thalassia hemprichii collected from Menjangan Kecil Waters, KarimunjawaIslands were screened to produce the pigment and has allowed the use of these microrganism as anenvironmental friendly alternative source of new natural pigment. The isolation of bacterial symbionts onZobell 2216E medium from seagrass Thalassia hemprichii resulted in 20 isolates of which 8 bacterialsymbionts have produced pigments but only one bacterium positively synthesize carotenoids. Initial analysiswith atomic absorption spectrophotometric method revealed that the wave lengt of bacterial pigment were inthe range of 300-600 nm, which are categorized that within the group of carotenoid pigments. From theresults of molecular identification by 16S rDNA method, it was shown that bacterium TH8 was closelyrelated to Bacillus licheniformis with 98% homology value
