Beauty and the Flirt: Male Physical Attractiveness and Approaches to Relationship Initiation

This multi-study investigation explored how women evaluate men’s approach strategies. In Study 1, 330 participants generated 546 verbal strategies used in courtship initiation. Strategies were rated on three dimensions that define relationships: affiliation, dominance, and explicitness. Affiliation and explicitness were related to strategy flirtatiousness. In Study 2, 361 females participated in an experiment that explored the effects of four approach strategies used by an attractive or unattractive man on conversation continuance and future interaction. Attractive men using inviting, playful, and less annoying messages were most successful. Study 3 (N = 398) replicated Study 2 using different approach strategies, and also demonstrated male attractiveness, affiliation and explicitness inform message flirtatiousness and influence courtship outcomes. Results suggest approach strategy, but not male attractiveness, influence perceived first date goals

Avaliação quali-quantitativa de algas marinhas macrófitas ocorrentes na Praia da Vigia, Garopaba/SC

O estudo teve por objetivo, identificar espécies e conhecer a estrutura da comunidade de algas da Praia da Vigia, Garopaba, Santa Catarina, pertencentes aos filos Rhodophyta (algas vermelhas), Phaeophyta (algas pardas) e Chlorophyta (algas verdes). Foram distribuídas 100 unidades amostrais de 0,25 m² de modo aleatório em nove pontos ao longo da praia, considerando locais de submersão contínua e imersão temporária. Foram registradas 15 espécies. O filo Rhodophyta foi representado por sete espécies, seguido por Chlorophyta e Phaeophyta, com cinco e três espécies cada. Os índices de diversidade estimados pelo Shannon (H’) e equabilidade de Pielou (J) foram, respectivamente, 1,95 nats.ind.-1 e 0,72. Os resultados obtidos indicam que a espécie de maior valor de importância foi Ulva lactuca, seguida por Chaetomorpha antennina e Sargassum cymosum. Além dos baixos valores de diversidade, houve pouca diferença na estrutura da comunidade e a distribuição das espécies entre os locais de inundação constante e temporária foi pequena

Hydrogen Isotopic Composition of Water in the Martian Atmosphere and Released from Rocknest Fines

The Mars Science Laboratory Curiosity rover sampled the aeolian bedform called Rocknest as its first solid samples to be analyzed by the analytical instruments CheMin and SAM. The instruments ingested aliquots from a sieved sample of less than 150 micrometer grains. As discussed in other reports at this conference [e.g., 1], CheMin discovered many crystalline phases, almost all of which are igneous minerals, plus some 10s of percent of x-ray amorphous material. The SAM instrument is focused on understanding volatiles and possible organics in the fines, performing evolved gas analysis (EGA) with the SAM quadrapole mass spectrometer (QMS), isotope measurements using both the QMS and the tunable laser spectrometer (TLS), which is sensitive to CO2, water and methane, and organics with the gas chromatograph mass spectrometer (GCMS). As discussed in the abstract by Franz et al. [2] and others, EGA of Rocknest fines revealed the presence of significant amounts of H2O as well as O-, C- and S-bearing materials. SAM has also tasted the martian atmosphere several times, analyzing the volatiles in both the TLS and QMS [e.g., 3,4]. This abstract will focus on presentation of initial hydrogen isotopic data from the TLS for Rocknest soils and the atmosphere, and their interpretation. Data for CO2 isotopes and O isotopes in water are still being reduced, but should be available by at the conference

How Accessible Was Information about H1N1 Flu? Literacy Assessments of CDC Guidance Documents for Different Audiences

We assessed the literacy level and readability of online communications about H1N1/09 influenza issued by the Centers for Disease Control and Prevention (CDC) during the first month of outbreak. Documents were classified as targeting one of six audiences ranging in technical expertise. Flesch-Kincaid (FK) measure assessed literacy level for each group of documents. ANOVA models tested for differences in FK scores across target audiences and over time. Readability was assessed for documents targeting non-technical audiences using the Suitability Assessment of Materials (SAM). Overall, there was a main-effect by audience, F(5, 82) = 29.72, P<.001, but FK scores did not vary over time, F(2, 82) = .34, P>.05. A time-by-audience interaction was significant, F(10, 82) = 2.11, P<.05. Documents targeting non-technical audiences were found to be text-heavy and densely-formatted. The vocabulary and writing style were found to adequately reflect audience needs. The reading level of CDC guidance documents about H1N1/09 influenza varied appropriately according to the intended audience; sub-optimal formatting and layout may have rendered some text difficult to comprehend

Selected isotope ratio measurements of light metallic elements (Li, Mg, Ca, and Cu) by multiple collector ICP-MS

The unique capabilities of multiple collector inductively coupled mass spectrometry (MC-ICP-MS) for high precision isotope ratio measurements in light elements as Li, Mg, Ca, and Cu are reviewed in this paper. These elements have been intensively studied at the Geological Survey of Israel (GSI) and other laboratories over the past few years, and the methods used to obtain high precision isotope analyses are discussed in detail. The scientific study of isotopic fractionation of these elements is significant for achieving a better understanding of geochemical and biochemical processes in nature and the environment
