Changing the alert levels is not done lightly.
…an increase in levels of low-density lipoprotein (LDL) cholesterol.
The findings address the mystery behind rising levels of methane in the atmosphere.
In evolutionary biology, the “levels” of selection under discussion are levels of scale.
Each of the four levels of the world contains other levels, organized according to a variety of patterns.
The roles available are at various levels of experience, from junior levels to more experienced senior editorial levels.
The expression levels of each gene were normalized to β-actin expression levels and adjust to the levels in Glut1 (served as 1).
Besides levels of organization, there are levels of abstraction, realization, being, analysis, processing, theory, science, complexity, and many others.
First, levels are compositional and form nested hierarchical structures, so that wholes at lower levels function as parts at higher levels.
Interestingly, the levels of antibodies patients produced seemed to correlate with their ages: Middle-aged and elderly recovered patients had higher levels of antibodies.
Indeed, knockdown of RalA, but not RalBP1, significantly reduced surface levels of GluR2 (Figure 7D), suggesting that surface GluR2 levels are maintained by RalA but not RalBP1.
Interestingly, this growing body of literature on levels in evolutionary biology is almost entirely disconnected from the debates on levels in philosophy of science discussed above.
…a potential challenge to the class structure of society, fashion generally flows from the higher levels to the lower levels, providing a continuous verification of class differences.
The categories of higher levels have nothing to do with the concreta of lower levels; the categories of lower levels are not principles of the categories of higher levels (A.56c).
We know from the same countries that low levels of inequality, high levels of redistributive taxation and of public provision are associated with high levels of innovation and other indicators of economic success.
In this light, it is clear that levels of mechanisms are only distantly related to earlier attempts at elucidating levels in the life sciences, and have many features that we intuitively would not associate with the idea of levels (Eronen 2013, 2015).
However, while raised levels of the protein PSA in the blood are linked to prostate cancer, about 75 per cent of men with high levels turn out to not have aggressive cancer that needs treatment and about 15 per cent of men with cancer have normal levels of PSA.
We conducted a five-way repeated measures ANOVA including factors of session (two levels: pre, post) × area (four levels: frontal ROIs) × hemisphere (two levels: left and right) × structural scan (two levels) × group (two levels: Dis Controls, NoDis Controls).
This idea that levels of organization of organization form “nested” compositional hierarchies where there are wholes at higher levels and their components at lower levels, and the components themselves can be further decomposed into parts, remains one of the core features of the notion of levels of organization up to this day.
Levels of mechanisms share some key features with the more standard accounts of levels of organization: They are by definition compositional, entities at higher levels are typically larger than entities at lower levels, and levels of mechanisms can potentially amount to local peaks of regularity and predictability (Craver 2007: 190; see next section).
