Core self-evaluations. Core self-evaluations ( CSE) represent a stable personality trait which encompasses an individual's subconscious, fundamental evaluations about themselves, their own abilities and their own control. People who have high core self-evaluations will think positively of themselves and be confident in their own abilities.

An ore deposit model is a conceptual and/or empirical standard, ideally a population of natural phenomena, embodying both the descriptive features of the deposit type, the larger ore-bearing environment, and an explanation of these features in terms of geological, and hence of chemical and physical, processes.

· Lead isotope data are generally reported as ratios of radiogenic isotopes normalized to the non-radiogenic isotope 204 Pb (e.g. 206 Pb/ 204 Pb, 207 Pb/ 204 Pb and 208 Pb/ 204 Pb). These ratios can be used in exploration to characterize the style of mineralization, metal (i.e. Pb) source and as vectors to ore.
