Finally, certain offers refer to the notion of reciprocity.

For the Alliance of Civilizations to have any chance of success, the emphasis must be on reciprocity.

But this correlation goes missing when one looks at the dimension of time rather than space.

In mathematics, dimension theory is a branch of commutative algebra studying the notion of the dimension of a commutative ring, and by extension that of a scheme.

In ring theory, a branch of abstract algebra, a commutative ring is a ring in which the multiplication operation is commutative.

Commutative diagrams play the role in category theory that equations play in algebra (see Barr Wells, Section 1.7).

Market fragmentation in the more diversified economies is often due to intraregional investment priorities in non tradable sectors, particularly real estate.

Only a stronger Europe will at last implement the principle of reciprocity in order to protect European businesses and prevent them from relocating, which has been the main cause of unemployment.

In 1998 we examined OECD data for a correlation between national unemployment rates in the mid 1990 s and current tax rates on labor.

There are not even crude gross correlation based estimates of the size of this effect, but economists believe that it is very real. Would it cost a negligible number of jobs?

Developing countries that have been enjoying non reciprocal preferential market access have called for adequately addressing the erosion of preferences arising from the most favoured nation tariff reduction.

But suspicion of the IMF persists, and most countries, especially in Asia, still prefer costly self insurance to a form of mutualization perceived as uncertain.

In commutative algebra, the constructible topology on the spectrum formula_1 of a commutative ring formula_2 is a topology where each closed set is the image of formula_3 in formula_1 for some algebra B over A .

The gross correlations between productivity growth and average unemployment found in the 1970 s, 1980 s, 1990 s, and 2000 s would increase the economy s natural rate of unemployment by about one fifth of a percentage point, costing an additional 500,000 jobs.

The bottom board of this three dimensional, the board of transnational relations, things that cross borders outside the control of governments, things like climate change, drug trade, financial flows, pandemics, all these things that cross borders outside the control of governments, there nobody's in charge.
