Transition Words • • • A Comprehensive List As a "part of speech" transition words are used to link words, phrases or sentences. They help the reader to progress from one idea (expressed by the author) to the next idea. Thus, they help to build up coherent relationships within the text. Transitional Words This structured list of commonly used English transition words — approximately 200, can be considered as quasi complete. There is some overlapping with prepositions and postpositions, but for the purpose of usage and completeness of this concise guide, I did not differentiate. Agreement / Addition / Similarity The transition words like also, in addition, and, likewise, add information, reinforce ideas, and express agreement with preceding material. in the first place not only ... but also as a matter of fact in like manner in addition coupled with in the same fashion / way first, second, third in the light of not to mention to say nothing of equally important by the same token again to and also then equally identically uniquely like as too moreover likewise
Matières Vivantes » Faut-il boycotter Elsevier ? On a déjà longuement discuté ici des problèmes liés aux revues scientifiques et des possibilités offertes par l’accès libre. Mais certaines pratiques récentes du grand éditeur Elsevier posent vraiment la question aujourd’hui d’un boycott pur et simple. Elsevier est un acteur quasi-incontournable de l’édition scientifique, publiant 250 000 articles par an dans plus de 2000 journaux (si j’en crois Wikipedia). Poids lourd de l’édition scientifique, sa responsabilité est grande, tant à l’égard de la Science – Elsevier édite par exemple les Compte Rendus de l’Académie des Sciences de notre beau pays- que des scientifiques qui, rappelons-le, travaillent quasiment gratuitement pour les éditeurs scientifiques du fait du système de revue par les pairs. Cependant, force est de constater que l’ attitude d’Elsevier pose des problèmes de façon récurrente. On le voit, Elsevier est donc régulièrement pris les mains dans le pot à confitures.
10 Search Engines to Explore the Deep End of the Invisible Web The Invisible Web refers to the part of the WWW that’s not indexed by the search engines. Most of us think that that search powerhouses like Google and Bing are like the Great Oracle”¦they see everything. Unfortunately, they can’t because they aren’t divine at all; they are just web spiders who index pages by following one hyperlink after the other. But there are some places where a spider cannot enter. Take library databases which need a password for access. Search engine technology has progressed by leaps and bounds. To get a more precise idea of the nature of this “˜Dark Continent’ involving the invisible and web search engines, read what Wikipedia has to say about the Deep Web. How do we get to this mother load of information? That’s what this post is all about. Infomine Infomine has been built by a pool of libraries in the United States. You can search by subject category and further tweak your search using the search options. The WWW Virtual Library Intute Complete Planet Infoplease

THE BRAIN FROM TOP TO BOTTOM One of these structures is the hypothalamus, and more specifically its suprachiasmatic nucleus, which receives a certain number of connections from retinal axons. The suprachiasmatic nucleus is considered the primary site of the body's internal biological clock. The visual signals that it receives from the retinal axons keep it continuously informed about the darkness or lightness of the environment, thus enabling it to synchronize a wide range of biological rhythms, including sleep and wakefulness, that are linked to the cycle of day and night. Axons from some other retinal ganglion cells project to the pretectum, a part of the midbrain that controls the opening of the pupil and certain eye movements. Lastly, about 10% of the axons emerging from the retina project to a part of the tectum (roof) of the midbrain called the superior colliculus. Like the lateral geniculate nucleus, the superior colliculus also receives connections from the primary visual cortex.
Multiple Regression with Two Predictor Variables - Text Multivariate Statistics: Concepts, Models, and Applications David W. Stockburger Multiple regression is an extension of simple linear regression in which more than one independent variable (X) is used to predict a single dependent variable (Y). The predicted value of Y is a linear transformation of the X variables such that the sum of squared deviations of the observed and predicted Y is a minimum. With two independent variables the prediction of Y is expressed by the following equation: Y'i = b0 + b1X1i + b2X2i Note that this transformation is similar to the linear transformation of two variables discussed in the previous chapter except that the w's have been replaced with b's and the X'i has been replaced with a Y'i. The "b" values are called regression weights and are computed in a way that minimizes the sum of squared deviations in the same manner as in simple linear regression.
