Most, but not all, GSSPs are based on paleontological changes.

Hence GSSPs are usually described in terms of transitions between different faunal stages, though far more faunal stages have been described than GSSPs.

GSSAs, and the generally more recent and preferred benchmark GSSPs ( below ) are defined by the International Commission on Stratigraphy ( ICS ) under the auspices of their parent organization, the International Union of Geological Sciences ( IUGS ), and are used primarily for time dating of rock layers older than 630 million years ago (), before a good fossil record exists.

In contrast to GSSAs, GSSPs are based on important events and transitions within a particular stratigraphic section.

The effort to define GSSPs is conducted by the International Commission on Stratigraphy, a part of the International Union of Geological Sciences.

As of 2004, 45 of the 96 GSSPs required have been approved.

Such a system could rely on events in the stratigraphic record and be demarcated by GSSPs.

One of its main aims, a project begun in 1974, is to establish a multidisciplinary standard and global geologic time scale that will ease paleontogical and geobiological comparisons region to region by benchmarks with stringent and rigorous strata criteria called Global Boundary Stratotype Section and Points ( GSSPs ) within the fossil record.

The ICS first expends large effort to meet the standards of the GSSPs ( see below ) and if those fail, usually have enough information to make a preliminary selection of several competing GSSA prospects or proposals.

All the drivers knew about the plates and they also knew about the big floppy straw hat with shredded edges, the kind natives in travel ads wear when they are out joyfully chopping cane.

I think that we are here also talking of the kind of fear that a young boy has for a group of boys who are approaching at night along the streets of a large city.

The networks for military communications are one of the best examples of networks which not only must be changed with the changes in objectives but also must be changed with the addition of new machines of war.

We are also struck by the fact that this story of a boy's love for his mother does not offend, while the incestuous love of the man, Paul Morel, sometimes repels.

He and also Mr. Cowley and Mr. Warren have fallen to the temptation which besets many of us to read into our authors -- Nathaniel Hawthorne, for example, and Herman Melville -- protests against modernism, material progress, and science which are genuine protests of our own but may not have been theirs.

On December 21, the day that the Irish House of Commons petitioned for removal of Sir Constantine Phipps, their Tory Lord Chancellor, Molesworth reportedly made this remark on the defense of Phipps by Convocation: `` They that have turned the world upside down, are come hither also ''.

Very likely it will also include a recognition that the work we are reading reflects or `` belongs to '' some way of thought labelled as a `` school '' or an `` -ism '', i.e. a complex or `` syndrome '' of ideas occurring together with sufficient prominence to warrant identification.

Greek boys and girls also go for rock-and-roll, and the stations most tuned to are those carrying United States overseas programs.

They both measure literature by moral standards, and in their political writings both allow for censorship, but the differences between them are also significant.

We may further grant to those of her ( Poetry's ) defenders who are lovers of poetry and yet not poets, the permission to speak in prose on her behalf: let them show not only that she is pleasant but also useful to States and to human life, and we will listen in a kindly spirit ; ;

Occupational choices are also useful -- and interesting -- in bringing out clearly that values do not constitute the only component in goals and aspirations.

The students who are most willing to acquiesce in the suppression of civil liberties are also those who are most likely to be prejudiced against minority groups, to be conformist and traditionalistic in general social attitudes, and to lack a basic faith in people.

This finding is consistent also with the fact that student leaders are more likely to be supporters of the values implicit in civil liberties than the other students.

In this sense also, they are surely conformists.

Of course I hope Hal can also, but those hopes are much more faint ''.

The novel, which is not merely dystopian but also brilliantly satiric, describes a future America where one-sixteenth of the population, the men who run advertising agencies and big corporations, control the rest of the people, the submerged fifteen-sixteenths who are the workers and consumers, with the government being no more than `` a clearing house for pressures ''.

But I will also remind them that I have always been inclined to skepticism, to a kind of Laodicean lack of commitment so far as public affairs are concerned ; ;

If his dancers are sometimes made to look as if they might be creatures from Mars, this is consistent with his intention of placing them in the orbit of another world, a world in which they are freed of their pedestrian identities.

The problem is rather to find out what is actually happening, and this is especially difficult for the reason that `` we are busily being defended from a knowledge of the present, sometimes by the very agencies -- our educational system, our mass media, our statesmen -- on which we have had to rely most heavily for understanding of ourselves ''.

Data on the former are scanty, but there can be little doubt that the latter is sometimes born at a length greater than that of any of the others, thereby lending support to the belief that the anaconda does, indeed, attain the greatest length.

Experiments are often composed of several identical trials, and sometimes experiments themselves are repeated.

Binomial distributions were treated by James Bernoulli about 1700, and for this reason binomial trials are sometimes called Bernoulli trials.

Some phonetic features, for example glottal catch or murmur, are sometimes to be assigned to segmental phonemics and sometimes to accentual systems.

but sometimes arrangements also are made for high school students to attend, and evening extension courses also may be conducted.

While costs on this order are sometimes separately charged for in residential and commercial rates, in the form of a mere `` service charge '', they are more frequently wholly or partly covered by a minimum charge which entitles the consumer to a very small amount of gas or electricity with no further payment.

In later collages of both masters, a variety of extraneous materials are used, sometimes in the same work, and almost always in conjunction with every other eye-deceiving and eye-undeceiving device they can think of.

the language, however, is a proper object of scrutiny, and the effects of the language are palpable even if sometimes inevitable.
