(Table 1) Heat flow measurements in the Central Pacific during Cruise 48 of R/V Vityaz

Eight measurements of heat flow in the Pacific floor were made during Cruise 48 of R/V Vityaz; four on the Manihiki Plateau, three - on the Marcus-Necker Rise, and one - in the Hawaiian Trough. Higher than average heat flows, up to 3.2 HFU, were recorded on submarine uplifts.

Microstructure characterization of 316L deformed at high strain rates using EBSD

Specimens from split Hopkinson pressure bar experiments, at strain rates between ~ 1000–9000 s− 1 at room temperature and 500 °C, have been studied using electron backscatter diffraction. No significant differences in the microstructures were observed at different strain rates, but were observed for different strains and temperatures. Size distribution for subgrains with boundary misorientations > 2° can be described as a bimodal lognormal area distribution. The distributions were found to change due to deformation. Part of the distribution describing the large subgrains decreased while the distribution for the small subgrains increased. This is in accordance with deformation being heterogeneous and successively spreading into the undeformed part of individual grains. The variation of the average size for the small subgrain distribution varies with strain but not with strain rate in the tested interval. The mean free distance for dislocation slip, interpreted here as the average size of the distribution of small subgrains, displays a variation with plastic strain which is in accordance with the different stages in the stress-strain curves. The rate of deformation hardening in the linear hardening range is accurately calculated using the variation of the small subgrain size with strain.

Crecimiento y convergencia: a propósito de Quah.

Este artículo discute los resultados del trabajo de Quah sobre la convergencia entre países. Los resultados muestran que aunque el trabajo de Quah es demoledor en torno a la convergencia tipo beta y sigma, la estimación del núcleo estocástico es bastante discutible y, por lo tanto, la transición entre países queda reducida a una cadena de Markov de un paso.

Optimization of the Ion Source-Mass Spectrometry Parameters in Non-Steroidal Anti-Inflammatory and Analgesic Pharmaceuticals Analysis by a Design of Experiments Approach

The flow rates of drying and nebulizing gas, heat block and desolvation line temperatures and interface voltage are potential electrospray ionization parameters as they may enhance sensitivity of the mass spectrometer. The conditions that give higher sensitivity of 13 pharmaceuticals were explored. First, Plackett-Burman design was implemented to screen significant factors, and it was concluded that interface voltage and nebulizing gas flow were the only factors that influence the intensity signal for all pharmaceuticals. This fractionated factorial design was projected to set a full 2(2) factorial design with center points. The lack-of-fit test proved to be significant. Then, a central composite face-centered design was conducted. Finally, a stepwise multiple linear regression and subsequently an optimization problem solving were carried out. Two main drug clusters were found concerning the signal intensities of all runs of the augmented factorial design. p-Aminophenol, salicylic acid, and nimesulide constitute one cluster as a result of showing much higher sensitivity than the remaining drugs. The other cluster is more homogeneous with some sub-clusters comprising one pharmaceutical and its respective metabolite. It was observed that instrumental signal increased when both significant factors increased with maximum signal occurring when both codified factors are set at level +1. It was also found that, for most of the pharmaceuticals, interface voltage influences the intensity of the instrument more than the nebulizing gas flowrate. The only exceptions refer to nimesulide where the relative importance of the factors is reversed and still salicylic acid where both factors equally influence the instrumental signal.

Identifying and enhancing risk thresholds in the detection of elder financial abuse: A signal detection analysis of professionals' decision making

Background: Financial abuse of elders is an under acknowledged problem and professionals' judgements contribute to both the prevalence of abuse and the ability to prevent and intervene. In the absence of a definitive "gold standard" for the judgement, it is desirable to try and bring novice professionals' judgemental risk thresholds to the level of competent professionals as quickly and effectively as possible. This study aimed to test if a training intervention was able to bring novices' risk thresholds for financial abuse in line with expert opinion. Methods: A signal detection analysis, within a randomised controlled trial of an educational intervention, was undertaken to examine the effect on the ability of novices to efficiently detect financial abuse. Novices (n = 154) and experts (n = 33) judged "certainty of risk" across 43 scenarios; whether a scenario constituted a case of financial abuse or not was a function of expert opinion. Novices (n = 154) were randomised to receive either an on-line educational intervention to improve financial abuse detection (n = 78) or a control group (no on-line educational intervention, n = 76). Both groups examined 28 scenarios of abuse (11 "signal" scenarios of risk and 17 "noise" scenarios of no risk). After the intervention group had received the on-line training, both groups then examined 15 further scenarios (5 "signal" and 10 "noise" scenarios). Results: Experts were more certain than the novices, pre (Mean 70.61 vs. 58.04) and post intervention (Mean 70.84 vs. 63.04); and more consistent. The intervention group (mean 64.64) were more certain of abuse post-intervention than the control group (mean 61.41, p = 0.02). Signal detection analysis of sensitivity (Á) and bias (C) revealed that this was due to the intervention shifting the novices' tendency towards saying "at risk" (C post intervention -.34) and away from their pre intervention levels of bias (C-.12). Receiver operating curves revealed more efficient judgments in the intervention group. Conclusion: An educational intervention can improve judgements of financial abuse amongst novice professionals.

The Case of the 35 Gigabyte Digital Record: OCR and Digital Workflows

This presentation was given at the Panhandle Library Access Network's (PLAN) Innovation Conference: Digitization- Preserving the Past for the Future Conference on August 14th, 2015. The presentation uses a specific collection of directories as a case study of the complications librarians and archivists face in digitizing older materials that may also be quite large, such as a directory. Prime OCR and Abbyy Fine Reader are discussed and their pros and cons covered. Troubleshooting and editing with Adobe Photoshop is also discussed.

Self-affirmation before exposure to health communications promotes intentions and health behavior change by increasing anticipated regret

Health-risk information can elicit negative emotions like anticipated regret that may positively affect health persuasion. The beneficial impact of such emotions is undermined when target audiences respond defensively to the threatening information. We tested whether self-affirming (reflecting on cherished attributes) before message exposure can be used as strategy to enhance the experience of anticipated regret. Women were self-affirmed or not before exposure to a message promoting fruit and vegetable consumption. Self-affirmation increased anticipated regret and intentions reported following message exposure and consumption in the week after the intervention; regret mediated the affirmation effect on intentions. Moreover, results suggest that anticipated regret and intentions are serial mediators linking self-affirmation and behavior. By demonstrating the mediating role of anticipated regret, we provide insights into how self-affirmation may promote healthy intentions and behavior following health message exposure. Self-affirmation techniques could thus potentially be used to increase the effectiveness of health communication efforts.

Aceitação e eficácia de um programa de intervenção psicoeducativa para pais de crianças com asma: Estudo exploratório

Considerando a importância que a educação sobre a asma deve assumir no plano de gestão familiar da doença, e a falta de programas deste tipo em Portugal, construímos uma intervenção psicoeducativa breve para pais de crianças com asma entre os 7 e os 13 anos, visando a aquisição de atitudes mais positivas na gestão da doença. O estudo teve como objetivo avaliar a aceitação, eficácia e a satisfação relativa ao programa intervenção. Completaram a intervenção 10 mães, tendo participado nas 3 sessões de grupo e nos 3 momentos de avaliação (linha de base, final da intervenção e follow-up a 9 meses). Para além da recolha de informação sociodemográfica e clínica, aplicaram-se dois questionários, um de conhecimentos sobre a asma e outro de qualidade de vida da criança (DISABKIDS-37, versões pais e criança). Utilizou-se também uma entrevista sobre a gestão da asma pela família (FAMSS) na avaliação inicial e no follow-up. Os resultados evidenciaram uma melhoria moderada no conhecimento dos pais e nas práticas de gestão da asma, confirmando a utilidade de incluir a intervenção psicoeducativa nos cuidados às crianças com asma.

Estereotipo, prejuicio y discriminación hacia la mujer en el contexto laboral

Con el propósito de identificar las regularidades en los estereotipos, los prejuicios y las formas de discriminación, asociados a la mujer en el contexto laboral latinoamericano, se analizaron treinta estudios empíricos, publicados en revistas adscritas a las bases Redalyc y Psicodoc correspondientes al período de 2005 a 2015. Para el análisis se diseñó una matriz con las siguientes categorías: Título, autores, año, país, variables, objetivos, tipo de investigación, instrumento y resultados. La información se sometió a un análisis descriptivo y se concluyó que pese a que se ha generado una cultura de inclusión de la mujer en las organizaciones, persisten los prejuicios, estereotipos y conductas discriminatorias.
