Empirical model for plasticity-induced crack closure based on Kmax and Δk
No full textThe mean stress has a significant effect on crack propagation life and must be included in prediction models. However, there is no consensus in the fatigue community regarding the dominant mechanism explaining the mean stress effect. The concept of crack closure has been widely used and several empirical models can be found in literature. The stress ratio, R, is usually the main parameter of these models, but present numerical results showed a significant influence of Kmax. A new empirical model is therefore proposed here, dependent on Kmax and ΔK, with four empirical constants. The model also includes the effect of material's yield stress, and two additional parameters were defined to account for stress state and crack closure parameter. A comparison was made with Kujawski's and Glinka's parameters, for a wide range of loading conditions. ΔKeff lies between Kujawski's and Glinka's parameters, and some agreement is evident, although the concepts are quite different. The crack opening model was applied to literature results and was able to collapse da/dN-ΔK curves for different stress ratios to a single master curve

(2001). The ambiguity of play [La ambigüedad del juego]. Harvard University Press.One vital constant in pedagogical narratives is the link between children’s play and education. Study of their relationship from a philosophical perspective is marked by paradoxes and tensions that have often raised the implementation of their use in educational practice in differing and even opposing ways. This article seeks to set out new ways of interpreting the relationship between play and education from a conciliatory approach. This relationship is explored from the works of three contemporaneous pragmatist thinkers of the late nineteenth: Jane Addams, John Dewey, and George Mead. The results suggest that the possibility of a relationship between children’s play and education is not so much found in the development of potentially educational materials, an extraordinary teaching method, or strictly teaching the curriculum. Rather, the significant contribution is concentrated in the conviction that play could be crucial for the cultivation of democracy. Pragmatists such as Addams and Dewey relied on the aesthetic experience of play as one of the most powerful possibilities for not only keeping democracy alive but also cultivating a cosmopolitan citizenship.Una de las constantes vitales de las narrativas pedagógicas ha sido la vinculación del juego infantil con la educación. El estudio de su relación en perspectiva filosófica está teñido de paradojas y tensiones que, a menudo, han planteado la materialización de su uso en la práctica educativa de maneras diversas y hasta opuestas. Este artículo trata de contener nuevas formas de interpretación de las relaciones entre lo lúdico y lo educativo desde un enfoque conciliador. En este trabajo, dicha relación se explora desde las obras de tres pensadores pragmatistas coetáneos de finales del siglo xix: Jane Addams, John Dewey y George Mead. La presente contribución analiza cómo las obras de los tres autores sugieren que la posibilidad de la relación de lo lúdico y lo educativo no se encuentra tanto en el desarrollo de un material potencialmente educativo, un método de enseñanza extraordinario o el estricto desarrollo de un currículo escolar. Más bien, su aportación significativa se concentra en la convicción de que el juego podría ser crucial para el cultivo de la democracia. En concreto, Addams y Dewey confiaban en la experiencia estética del juego como una de las posibilidades más poderosas para no solo mantener viva la democracia, sino también cultivar una ciudadanía cosmopolita.Depto. de Estudios EducativosFac. de EducaciónTRUEpu
MeSH term explosion and author rank improve expert recommendations
No full textInformation overload is an often-cited phenomenon that reduces the productivity, efficiency and efficacy of scientists. One challenge for scientists is to find appropriate collaborators in their research. The literature describes various solutions to the problem of expertise location, but most current approaches do not appear to be very suitable for expert recommendations in biomedical research. In this study, we present the development and initial evaluation of a vector space model-based algorithm to calculate researcher similarity using four inputs: 1) MeSH terms of publications; 2) MeSH terms and author rank; 3) exploded MeSH terms; and 4) exploded MeSH terms and author rank. We developed and evaluated the algorithm using a data set of 17,525 authors and their 22,542 papers. On average, our algorithms correctly predicted 2.5 of the top 5/10 coauthors of individual scientists. Exploded MeSH and author rank outperformed all other algorithms in accuracy, followed closely by MeSH and author rank. Our results show that the accuracy of MeSH term-based matching can be enhanced with other metadata such as author rank
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

"Closing the R&D Gap, Evaluating the Sources of R&D Spending"
No full textBoth spending and tax policies have been implemented in the United States with the goal of stimulating private sector research and development (R&D). Karier questions whether current R&D policy, especially the research and experimentation tax credit, can contribute to closing the gap between nondefense expenditures on R&D in the United States and such expenditures in other countries, such as Japan and Germany. He also explores possible changes to our current R&D policy to make it more effective.
Comparison of Sheep and Goats to the Acute Toxic Effects of Foothill Death Camas
No full textDeath camas (Zigadenus spp) is a perennial forb found throughout the western United States, which is known to kill both sheep and cattle. In a previous study, goats appeared to be somewhat resistant to the adverse effects of death camas. Therefore, the objective of this study was to directly compare the susceptibility of goats and sheep to the acute toxic effects of death camas. Sheep and goats were dosed at 0.5, 1.0, 2.0, 4.0, and 6.0 g death camas per kg BW. The data presented in this manuscript suggest that goats are more susceptible to death camas than sheep. There were no differences in the serum concentrations of zygadenine in sheep versus goats. There was a difference between goats and sheep in the severity of observed clinical signs of poisoning. This is highlighted by the fact that five goats from the two highest doses died, whereas none of the sheep died. Consequently, when grazing goats in death camas infested pastures as much caution, if not more, should be taken than one would with sheep. Additionally, the data presented in the study suggests that goats can be used as a small ruminant model to study the toxic effects of death camas
Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
