Distress risk, growth and earnings quality

We extend and complement prior work by investigating the earnings quality of firms with different financial health characteristics and growth prospects. By using three alternative measures of default likelihood and two alternative measures of growth options, without being limited to a specific event, we provide a more comprehensive setup for analysing the earnings characteristics of the universe of firms than examining distressed firms with persistent losses, dividend reductions or bankruptcy-filings. Our dataset consists of 15,049 healthy U.S. firms over the period 1990-2004. Results show that the relation between earnings quality and financial health is not monotonic. Distressed firms have a low level of earnings timeliness for bad news and a high level for good news, and manage earnings toward a positive target more frequently than healthy firms. On the other hand, healthy firms have a high level of earnings timeliness for bad news. Growth aspects play an important role in a firm's ability to manage earnings. In contrast to the findings of prior studies, growth firms have greater earnings timeliness for bad news, whereas value firms manage earnings toward a positive target more frequently than growth firms. © 2011 The Authors.

Cooperative or collaborative learning: Is there a difference in university students’ perceptions?

The hypothesis that the same educational objective, raised as cooperative or collaborative learning in university teaching does not affect students’ perceptions of the learning model, leads this study. It analyses the reflections of two students groups of engineering that shared the same educational goals implemented through two different methodological active learning strategies: Simulation as cooperative learning strategy and Problem-based Learning as a collaborative one. The different number of participants per group (eighty-five and sixty-five, respectively) as well as the use of two active learning strategies, either collaborative or cooperative, did not show differences in the results from a qualitative perspective.

Shirley Winifred Jeffrey 1930–2014

Australian scientist Shirley Jeffrey was a pioneer in oceanographic research, identifying the then theoretical chlorophyll c, and was a worldwide leader in the application of pigment methods in quantifying phytoplankton as the foundation of the oceanic food supply. Her research paved the way for the successful application of microalgae in aquaculture around the world. Jeffrey earned bachelor's and master's degrees at University of Sydney, majoring in microbiology and biochemistry, followed by a PhD from the King's College London Hospital Medical School. Returning to Sydney, she was hired by the Commonwealth Scientific and Industrial Research Organisation (CSIRO) to research chlorophyll c. Following this successful effort, she became a research fellow at the University of California, Berkeley from 1962 to 1964. She then became affiliated with the Scientific Committee on Oceanic Research. After a 1973 sabbatical at the Scripps Institution of Oceanography in San Diego, she returned to CSIRO, where she spent the rest of her career.

La metáfora en los museos de historia social

Antes de la puesta en práctica de los archivos en papel en el siglo XIX había muchas formas líricas de conocer el pasado, por ejemplo, a través del canto y de la pintura. En la evolución de los museos del siglo XIX, los artefactos ocuparon el lugar del conocimiento correspondiente de la “verdad” que se creía existente en el papel archivado. El trabajo del Museo procedió con la certeza del sentido común de una correspondencia individualizada racional entre un artefacto y su significado. La confianza en la capacidad denotativa del artefacto era así la estrategia para transmitir significado a los visitantes. Los museos están alejándose ahora de la denotación como estrategia de comunicación primaria, y uno de los modos que surge es la metáfora. Así como se entendía antiguamente que el significado fijo de los objetos residía en su pura materialidad, ahora vemos el resurgir de la materialidad en los museos, pero esta vez a través de la metáfora, teóricamente entendida como apoyada en la experiencia material del mundo por parte de nuestros cuerpos humanos.

L’art de présenter Marguerite Duras à l’étranger : le cas de la Suède

Dans cette communication, nous proposons d’analyser les paratextes des ouvrages durassiens traduits en suédois. Nous nous intéressons surtout aux préfaces (et postfaces) allographes (cf. Genette, Seuils, 1987) ainsi qu’aux couvertures et quatrièmes de couverture. Pour les préfaces, postfaces et quatrièmes de couverture, nous voulons savoir, d’abord, dans quelle mesure il existe des textes allographes dans les traductions suédoises. Ensuite, nous nous intéressons aux références culturelles et artistiques données dans les présentations. Comme l’objectif de ces paratextes est d’introduire une auteure étrangère à un nouveau public et recommander son ouvrage aux acheteurs potentiels, il serait intéressant d’étudier les stratégies éditoriales : dans quel contexte intellectuel et artistique choisit-on d’inscrire Marguerite Duras ? Quels arguments et références sont utilisés ? Pour les couvertures, nous allons étudier l’utilisation des différentes expressions artistiques telles que les photographies, les dessins, les typographies spécifiques, etc. Nous voulons savoir, par exemple, s’il y a des motifs récurrents, et si le public ciblé est le même pour toutes les éditions. Le corpus sera constitué par des paratextes des éditions suédoises de l’oeuvre durassienne, du premier roman traduit (Stilla liv 1947 [La Vie tranquille]) jusqu’aux traductions les plus récentes. Nous tâcherons de savoir s’il y a eu des « médiateurs » prestigieux, c’est-à-dire des personnalités de grande notoriété qui ont contribué à l’introduction de Duras en Suède. Pour ce faire, nous allons discuter aussi le travail des traducteurs – car ces individus ont également participé à la promotion de l’oeuvre durassienne sur le marché suédois.

An elevated systolic blood pressure response at 8 minutes in full contact exercise may identify hypertensive subjects

The aim of this study was to identify hypertension (HT) in karate competitors (KCs) in high intensity exercise. Values were compared with an exercise control group (EC). The 84 subjects were randomly divided into two groups: KC and EC. Resting blood pressure (BP) was measured the day before and immediately precompetition. A further three measurements were taken postexercise for all subjects at 1-, 2-, and 8- minute intervals. At rest, day one, mean BP of KC was 134/84 ± 3/2 mmHg vs. EC, 124/72 ± 1/2 mmHg and on day 2, was 141/79 ± 3/2 mmHg vs. EC, 125/72 ± 1/2 mmHg, respectively. Eight minutes postcompetition, BP of KCs was 140/77 ± 2/1 mmHg vs. EC 135/75 ± 2/1 mmHg. High blood pressure (HBP) was recorded in 60.5% of KCs on day 2, and essential HT that required medical therapy was subsequently diagnosed in 5% of KCs. Five percent of EC also had HBP, but subsequent medical examination reported normal values.

The relationship between baseline blood pressure and computed tomography findings in acute stroke: data from the Tinzaparin in Acute Ischaemic Stroke Trial (TAIST)

Background and Purpose—High blood pressure (BP) is present in 80% of patients with acute ischemic stroke and is independently associated with poor outcome. There are few data examining the relationship between admission BP and acute CT findings. Methods—TAIST was a randomized controlled trial assessing 10 days of treatment with tinzaparin versus aspirin in 1489 patients with acute ischemic stroke (48 hr) with admission BP of 220/120 mm Hg. CT brain scans were performed before randomization and after 10 days. The relationships between baseline BP and adjudicated CT findings were assessed. Odds ratios per 10 mm Hg change in BP were calculated. Results—Higher systolic BP (SBP) was associated with abnormal CT scans because of independent associations with chronic changes of leukoariosis (OR, 1.12; 95% CI, 1.05–1.17) and old infarction (OR, 1.12; 95% CI, 1.06 –1.17) at baseline, and signs of visible infarction at day 10 (OR, 1.06; 95% CI, 1.00 –1.13). A lower SBP was associated with signs of acute infarction (OR, 0.94; 95% CI, 0.89–0.99). Hemorrhagic transformation, dense middle cerebral artery sign, mass effect, and cerebral edema at day 10 were not independently associated with baseline BP. Conclusion—Although high baseline BP is independently associated with a poor outcome after stroke, this was not shown to be through an association with increased hemorrhagic transformation, cerebral edema, or mass effect; trial design may be suboptimal to detect this. Higher SBP is associated with visible infarction on day 10 scans. The influence of changing BP in acute stroke on CT findings is still to be ascertained.
