Ratings of age of acquisition of 299 words across 25 languages: is there a cross-linguistic order of words?

We present a new set of subjective age-of-acquisition (AoA) ratings for 299 words (158 nouns, 141 verbs) in 25 languages from five language families (Afro-Asiatic: Semitic languages; Altaic: one Turkic language: Indo-European: Baltic, Celtic, Germanic, Hellenic, Slavic, and Romance languages; Niger-Congo: one Bantu language; Uralic: Finnic and Ugric languages). Adult native speakers reported the age at which they had learned each word. We present a comparison of the AoA ratings across all languages by contrasting them in pairs. This comparison shows a consistency in the orders of ratings across the 25 languages. The data were then analyzed (1) to ascertain how the demographic characteristics of the participants influenced AoA estimations and (2) to assess differences caused by the exact form of the target question (when did you learn vs. when do children learn this word); (3) to compare the ratings obtained in our study to those of previous studies; and (4) to assess the validity of our study by comparison with quasi-objective AoA norms derived from the MacArthur–Bates Communicative Development Inventories (MB-CDI). All 299 words were judged as being acquired early (mostly before the age of 6 years). AoA ratings were associated with the raters’ social or language status, but not with the raters’ age or education. Parents reported words as being learned earlier, and bilinguals reported learning them later. Estimations of the age at which children learn the words revealed significantly lower ratings of AoA. Finally, comparisons with previous AoA and MB-CDI norms support the validity of the present estimations. Our AoA ratings are available for research or other purposes.

Verbs in space: axis and direction of motion norms for 299 English verbs

A strong body of work has explored the interaction between visual perception and language comprehension; for example, recent studies exploring predictions from embodied cognition have focused particularly on the common representation of sensory—motor and semantic information. Motivated by this background, we provide a set of norms for the axis and direction of motion implied in 299 English verbs, collected from approximately 100 native speakers of British English. Until now, there have been no freely available norms of this kind for a large set of verbs that can be used in any area of language research investigating the semantic representation of motion. We have used these norms to investigate the interaction between language comprehension and low-level visual processes involved in motion perception, validating the norming procedure’s ability to capture the motion content of individual verbs.

O contínuo e a região estendida de linhas estreitas das galáxias ativas ESO 362-G18 e ESO 362-G8

Foram analisados espectros óticos de fenda longa das galáxias Seyfert 1 ESO362-G18 e Seyfert 2 ESO362-G8. Estas duas galáxias apresentam emissão por gás de alta excitação em forma anisotrópica, possivelmente devido a colimação por um tóro de poeira. O objetivo do presente trabalho consiste em estudar o contínuo e a região estendida de linhas de emissão (ENLR) destes objetos. Este trabalho constitui-se no primeiro estudo detalhado realizado sobre estas galáxias. A população estelar em cada galáxia e caracterizada em função da distância ao núcleo. O contínuo nuclear e estudado em termos de duas componentes: a população estelar e a componente AGN (\Active Galatic Nuclei"). Observa-se a presença desta componente AGN na gal axia Seyfert 1 ESO362-G18. A galáxia Seyfert 2 não permite observar esta componente AGN mesmo depois de subtraída a componente de população estelar. Nas duas galáxias observa-se importante contribuição de população de idade intermediária ( 5 108 anos). A partir das linhas estreitas de emissão, mapeamos a excitação do gás interestelar ao longo da ENLR. As razões entre estas linhas de emissão são reproduzidas a partir de um modelo de fotoionização de duas componentes - uma componente limitada por matéria ("matter-bounded") e uma componente limitada por ionização ("ionization-bounded"). Este modelo, construído utilizando o código de fotoionização MAPPINGS Ic, se propõe a resolver os problemas apresentados pelos modelos tradicionais de uma componente apenas. A partir dos resultados obtidos com o modelo de duas componentes, determinamos o fator de preenchimento e o fator de cobertura do gás em função da distância ao núcleo. Utilizamos estes parâmetros para testar a consistência do modelo proposto. Por fim realizase o cálculo de balanço de fótons e estuda-se a natureza do contínuo infravermelho (IR) médio e distante - comparando-se a luminosidade observada no IR, calculada a partir dos fluxos IRAS, com a luminosidade predita para um tóro que envolve a fonte modelada e re-emite a radiação incidente no infravermelho.

RP97-362 File It Easy, Find It Fast: A Home Filing System

A home filing system makes important papers readily available when needed. If managed properly, the filing system can get older papers out of the way, making needed records more accessible. A well-organized filing system for your household can pay big dividends when it comes time to find an important paper you need NOW. There is no one best filing system for everyone; what works for you could be a disaster for someone else. Once set up, a filing system helps you to be a more effective and efficient financial manager and decision maker.

High intestinal cholesterol absorption is associated with cardiovascular disease and risk alleles in ABCG8 and ABO: evidence from the LURIC and YFS cohorts and from a meta-analysis.

OBJECTIVES This study sought to determine whether high intestinal cholesterol absorption represents a cardiovascular risk factor and to link ABCG8 and ABO variants to cardiovascular disease (CVD). BACKGROUND Plant sterol-enriched functional foods are widely used for cholesterol lowering. Their regular intake yields a 2-fold increase in circulating plant sterol levels that equally represent markers of cholesterol absorption. Variants in ABCG8 and ABO have been associated with circulating plant sterol levels and CVD, thereby suggesting atherogenic effects of plant sterols or of cholesterol uptake. METHODS The cholestanol-to-cholesterol ratio (CR) was used as an estimate of cholesterol absorption because it is independent of plant sterols. First, we investigated the associations of 6 single nucleotide polymorphisms in ABCG8 and ABO with CR in the LURIC (LUdwisghafen RIsk and Cardiovascular health study) and the YFS (Young Finns Study) cohorts. Second, we conducted a systematic review and meta-analysis to investigate whether CR might be related to CVD. RESULTS In LURIC, the minor alleles of rs4245791 and rs4299376 and the major alleles of rs41360247, rs6576629, and rs4953023 of the ABCG8 gene and the minor allele of rs657152 of the ABO gene were significantly associated with higher CR. Consistent results were obtained for rs4245791, rs4299376, rs6576629, and rs4953023 in YFS. The meta-analysis, including 6 studies and 4,362 individuals, found that CR was significantly increased in individuals with CVD. CONCLUSIONS High cholesterol absorption is associated with risk alleles in ABCG8 and ABO and with CVD. Harm caused by elevated cholesterol absorption rather than by plant sterols may therefore mediate the relationships of ABCG8 and ABO variants with CVD.
