This paper empirically examines to what extent being foreign and part of a multinational affects the endogenous relation between R&D and productivity.
However, in this paper, we ignore the possible endogenous relation between the production and investment, mainly because of the weakness of the database to express that relation.
Nonetheless, the timing of changes in productivity and changes in hours suggests the possibility of an endogenous relation between the two.
This cross-sectional study, designed to examine whether leptin or insulin may mediate the endogenous relation of obesity with metabolic, inflammatory, and thrombogenic cardiovascular risk factors, included 522 men and 514 women aged ≥40 years who completed a physical examination during the third National Health and Nutrition Examination Survey.
The objective of this study was threefold: (i) to construct a (endogenous) relation between cost development and cumulative production (ii) to implement technological learning based on both engineering study insights and an experience curve approach, and (iii) to investigate the impact of different technological learning assumptions on the market diffusion patterns of different biofuels.
The endogenous exposure relation found for postmenopausal exposed women is consistent with data on male smelter workers, whereas the relation found for premenopausal women is significantly lower.
Quantitative data are now available on endogenous adducts, and relation between endogenous and exogenous adducts.
The expression of the endogenous markers in relation to the vessels, with pimonidazole as a reference hypoxic marker, can provide valuable information about their usefulness as a marker of chronic hypoxia.
Minor stress and probably also major stress are therefore not accompanied by an adequate stress response, especially over a long time, which leads to inadequately low concentrations of stress axes mediators (that is, endogenous glucocorticoids) in relation to the immune/inflammatory situation [ 5].
Most prospective studies on endogenous hormones in relation to breast cancer risk have been undertaken among postmenopausal women because of difficulties relating to menstrual timing of sampling among premenopausal women, the relative frequency of postmenopausal and premenopausal breast cancer, and the age spectrum of most established cohorts.
