It is hypothesized that fertility is a function of the social system when the population as a whole is considered and a function of the subsystems when the two-fold division of core families and marginal families is considered.

The great majority of present-day linguists fall into one or more of a number of overlapping types: those who are convinced that tone cannot be analysed, those who are personally scared of tone and tone languages generally, those who are convinced that tone is merely an unnecessary marginal feature in those languages where it occurs, those who have no idea how to proceed with tone analysis, those who take a simplistic view of the whole matter.

Since marginal costs rise when the wage rate rises, the profit-maximizing price also rises when the public-limit price is elevated, and is likely to remain well above the latter.

We assume that average total unit cost in the relevant region of operation is constant with respect to quantity produced ( the average cost curve is horizontal, and therefore is identical with the marginal cost curve ), and is the same for every firm ( and therefore for the industry ).

The level of average cost ( equal to marginal cost ) is thus strictly a function of the wage rate.

By all means the most important distinction is that between those total-cost apportionments which superimpose a distribution of admittedly unallocable cost residues on estimates of incremental or marginal costs, and those other apportionments which recognize no difference between true cost allocation and mere total-cost distribution.

Here no attempt is made, first to determine out-of-pocket or marginal costs and then to superimpose on these costs `` reasonably distributed '' residues of total costs.

If this analysis is correct, the suburban branches will turn out to be what management's cost accountants refuse to acknowledge, marginal operations rather than major factors.

The result, coupled with the salesmanship for which American industry is famous, is considerable expenditure of funds and efforts in marginal areas.

The industry is so structured that price-setting by a multi-product company will vary with the way overhead charges are allocated -- whether marginal or average pricing is applied.

Although the theological forms of the past continue to exist in a way they do not in a more secularized situation, the striking thing is the rapidity with which they are being reduced to a marginal existence.

The bestiary in the Queen Mary Psalter is found in the " marginal " decorations that occupy about the bottom quarter of the page, and are unusually extensive and coherent in this work.

This is particularly so in Chad, where the openness of the terrain, marginal rainfall, frequent drought and famine, and low population densities have encouraged physical and linguistic mobility.

A downward spiral is created in many underdeveloped countries by overgrazing, land exhaustion and overdrafting of groundwater in many of the marginally productive world regions due to overpopulation pressures to exploit marginal drylands for farming.

So the exchange of consumer goods establishes prices that represent the marginal utility of consumers, and money therefore is representative of consumer satisfaction.

Traffic of smaller vessels at Elbląg is within the river and very marginal, while larger vessels cannot reach the open Baltic Sea because the channel, once built in East-Prussia to go through the peninsula, has belonged to Russia since 1945.

The field, then, is ripe for new Southerners to step to the fore and write of this twentieth-century phenomenon, the Southern Yankeefication: the new urban economy, the city-dweller, the pains of transition, the labor problems ; ;

This bold self-assertion, after decades of humble subservience, is indeed a twentieth-century phenomenon, an abrupt change in the Southern way of existence.

One, a reservation on the point I have just made, is the phenomenon of pseudo-thinking, pseudo-feeling, and pseudo-willing, which Fromm discussed in The Escape From Freedom.

Because of the means of publication -- science-fiction magazines and cheap paperbacks -- and because dystopian science fiction is still appearing in quantity the full range and extent of this phenomenon can hardly be known, though one fact is evident: the science-fiction imagination has been immensely fertile in its extrapolations.

What makes the current phenomenon unique is that so many science-fiction writers have reversed a trend and turned to writing works critical of the impact of science and technology on human life.

I would, however, like to suggest that, wrong though I may be, the tendency to see dilemmas rather than solutions is one of which I have been a victim ever since I can remember, and therefore not merely a senile phenomenon.

This is a phenomenon familiar to all radio listeners, resulting from reflection of skywave signals at night from the ionized layer in the upper atmosphere known as the ionosphere.

Zodiacal light and the gegenschein give some evidence for such a dust blanket, a phenomenon also to be expected if the dust before capture is in circular orbits about the sun, as indicated by the trend of the smaller visible meteors.

The Maturity Chart for each sex demonstrates clearly that Onset is a phenomenon of infancy and early childhood whereas Completion is a phenomenon of the later portion of adolescence.

that is, we may discuss the phenomenon in terms of its departures from the binomial model.

Autosuggestibility, the reaction of the subject in such a way as to conform to his own expectations of the outcome ( i.e., that the arm-rise is a reaction to the pressure exerted in the voluntary contraction, because of his knowledge that `` to every reaction there is an equal and opposite reaction '' ) also seems inadequate as an explanation for the following reasons: ( 1 ) the subjects' apparently genuine experience of surprise when their arms rose, and ( 2 ) manifestations of the phenomenon despite anticipations of something else happening ( e.g., of becoming dizzy and maybe falling, an expectation spontaneously volunteered by one of the subjects ).

this is a question which I have no wish to take up -- condensation is a phenomenon in which one finds not a condensed expression of various feelings and ideas which are, at an unconscious level, well sorted out, but rather a condensed expression of feelings and ideas which, even in the unconscious, have yet to become well differentiated from one another.

The paper has a certain value as a comparatively easy introduction to this approach, particularly since it treats a fairly simple and straightforward phenomenon where it is possible to compare it with a more traditional ( though not structural ) statement.

Sprouting is a naturally occurring phenomenon in stored potatoes, onions, carrots, beets, and similar root vegetables.

At low thicknesses a cutting ( or shearing ) phenomenon is often encountered.

Every dream, and this is true of a mental image of any type even though it may be readily interpreted into its equivalent of wakeful thought, is a psychic phenomenon for which no explanation is available.

The concept of unity, in which positive and negative are attributes of the same force, in which good and evil are relative, ever-changing, and always joined to the same phenomenon -- such a concept is still reserved to the physical sciences and to the few who have grasped the history of ideas.

Too many people think that the primary purpose of a higher education is to help you make a living ; ;

The strong feeling is certainly there ; ;

Since the Supreme Court's decision of that year this is more doubtful ; ;

Their own easier, slower tempo is especially dear to Southerners ; ;

BMEWS intelligence is simultaneously flashed to NORAD ( North American Air Defense Command ) in Colorado Springs, Colorado, for interpretation ; ;

They include the Navy's Atlantic Command at Norfolk, Virginia, which is in contact with the Polaris subs ; ;

The aborigine is not deceived ; ;

In spots such as the elbows and knees the second skin is worn off and I realized the aborigines were much darker than they appeared ; ;

For one thing, there is a natural belt of rock across the river bed ; ;

for example, the mode of bravery to this anonymous folk poem: `` They brought me news that Spring is in the plains And Ahmad's blood the crimson tulip stains ; ;

`` It is easy for you to talk '' ; ;

It is interesting, however, that despite this strong upsurge in Southern writing, almost none of the writers has forsaken the firmly entrenched concept of the white-suited big-daddy colonel sipping a mint julep as he silently recounts the revenue from the season's cotton and tobacco crops ; ;

This is not to say that the South is no longer agrarian ; ;
