It is clear that the carbon cycle and global climate are linked in many ways throughout the history of the Earth. But it is equally apparent that the complex interactions evident in the geologic record defy simple attribution of cause and effect. Collection of more data and further analysis and modeling will continue to improve our understanding of these interactions, which are now so important to the near-term relationship between human activities and the global environment. [Pg.4325]

The data are collected daily from a number of sources, including the National Center for Biotechnology Information (NCBI) and Gene Ontology (GO) Consortium. The warehouse includes sequences, structures, and complete genomes from Gen-Bank as well as annotation links such as NCBI taxon database terms, redundant sequences, sequence neighbors, conserved domains, Online Mendehan Inheritance in Man identifiers, GO terms, LocusLink identifiers, and PubMed links. [Pg.393]

Finally, the research examined below tends to link variables within cases for example, data on accidents, age, and job tenure are collected from the same employee (sample of employees) and correlated. While this research clearly shows that new employees suffer accidents, it potentially misses the impact of new employees on their co-workers safety. It is also very likely that some of the accidents suffered by employees that have been working for an organization for some time (what might be termed seiuor employees) may involve a new employee as part of the causal mechanism. Indeed, responsibiUly for industrial fatalities/ accidents has been associated with the fellow worker for over 100 years (see Eastman 1910 Swuste et al. 2010). Thus, overall, new employees are both a safety risk to themselves and potentially a safety risk to all employees in an organization. [Pg.10]

More recently, new quantitative structure-property relationships for Tg have been developed (1) they are based on the statistical analysis of experimental data for 320 linear (uncross-linked) polymers collected from many different sources, containing a vast variety of compositions and structural features. The Tg of the atactic form was used, whenever available, for polymers manifesting different tac-ticities. The Tg values of a subset of the polymers listed in this extensive tabulation are reproduced (with some minor revisions) in Table 1. (It is important to caution the reader here that these data were assembled from a wide variety of sources. Many different experimental techniques were used in obtaining these data.) The resulting relationship for Tg has the form of a weighted sum of structural terms mainly taking the effects of chain stiffness into account plus a term proportional to the solubility parameter S which takes the effects of cohesive interchain interactions in an explicit manner, as shown in equation (1) ... [Pg.3580]
