Examples of selective negligence in the following topics:
-
- For example, students may adopt a strategy of selective negligence. within the first month of classes, many students discover they cannot conceivably complete all the work assigned them; consequently, they must selectively neglect portions of the formal schoolwork.

- Racemization of the α-carbon is possible, but seems to be negligible.
- Other procedures for removing the auxiliary have also been developed, with lithium hydroperoxide being particularly selective thanks to the alpha effect.
- Steric hindrance of the Lewis acid with the Z-methyl group changes the facial selectivity of the aldehyde from re to si.
- In order to reverse this selectivity, a bulkier silyl substituent is introduced and the magnesium is exchanged with a triisopropoxidetitanium moiety.
- Once again, chelation is prevented, and dipole opposition causes a reversal in facial selectivities, leading to the enantiomeric anti-aldol product.
-
- Issue voting is the process by which voters select candidates based on how closely their views on certain issues match the voter's own.
- Also, they can obscure issues by reporting through negligence and distraction.
-
- If, however, the stereogenic center is far away from the carbonyl group, it has a negligible influence on the reduction, and a nearly 50:50 mixture of diastereomers is produced (lower example).
- Many conformations about the alpha-C-CO bond may be written, and the challenge is to pick one that accounts for the observed selectivity.
- This diastereoselectivity is commonly termed Cram or Felkin selectivity.
- This change in stereoselectivity is sometimes termed anti-Cram or anti-Felkin selectivity.
- Alternatively, intramolecular control may provide selectivity, as shown in equation 3.
-
- The concept of checks and balances was embodied in a provision that legislative acts could be vetoed by a council composed of the executive and selected members of the judicial branch.
- The free states found the compromise negligible when compared with the ultimate goal of writing a new governing document, and slave states were satisfied by this provision and agreed to support the plan.
-
- It is reasonable to assume negligible resistance because in practice we can make the resistance of an inductor so small that it has a negligible effect on the circuit.
- (a) An AC voltage source in series with an inductor having negligible resistance.
-
- If natural selection favors an average phenotype by selecting against extreme variation, the population will undergo stabilizing selection.
- When the environment changes, populations will often undergo directional selection, which selects for phenotypes at one end of the spectrum of existing variation.
- Sometimes natural selection can select for two or more distinct phenotypes that each have their advantages.
- Diversifying selection occurs when extreme values for a trait are favored over the intermediate values.This type of selection often drives speciation.
- Different types of natural selection can impact the distribution of phenotypes within a population.In (a) stabilizing selection, an average phenotype is favored.In (b) directional selection, a change in the environment shifts the spectrum of phenotypes observed.In (c) diversifying selection, two or more extreme phenotypes are selected for, while the average phenotype is selected against.
-
- For $h\nu \gg\ k T$ the exponential is negligible so $\alpha_\nu \propto \nu^{-3}$.
-
- Natural selection drives adaptive evolution by selecting for and increasing the occurrence of beneficial traits in a population.
- Natural selection only acts on the population's heritable traits: selecting for beneficial alleles and, thus, increasing their frequency in the population, while selecting against deleterious alleles and, thereby, decreasing their frequency.
- Natural selection does not act on individual alleles, however, but on entire organisms.
- Natural selection acts at the level of the individual; it selects for individuals with greater contributions to the gene pool of the next generation, known as an organism's evolutionary fitness (or Darwinian fitness).
- Through natural selection, a population of finches evolved into three separate species by adapting to several difference selection pressures.
-
- Clonal selection and tolerance select for survival of lymphocytes that will protect the host from foreign antigens.
- Clonal selection occurs after immature lymphocytes express antigen receptors.
- The preservation of useful specificities is called positive selection.
- Negative selection of developing lymphocytes is an important mechanism for maintaining central tolerance.
- clonal selection of the B and T lymphocytes:1.
