Young children are fundamental elements of societal progress. Consequently, cultivating adeptness in early childhood education and childcare talents assumes paramount significance, with educators within tertiary colleges universities taking a pivotal role therein. Furthermore, research literacy is what develop through applying theoretical knowledge deemed an indispensable competency effective i...

in the process of investment decision making, next to financial indicators many other aspects of investment projects are increasingly often considered. this leads to the multi-criteria evaluation of a project. the advantage of multi-criteria methods is the ability to take into account all (not only financial) aspects of the attractiveness of an investment project. the selection of criteria of p...

making capital and investment is the main driving forces of economic development. based on the investment sensitivity to the changes of some of macro-economic variables and risk and uncertainty, the present study evaluated the effective factors on investment in private sector in iran during 1980-2007. at first, the uncertainty variables of real informal exchange rate, nominal interest rate and ...

investment in oil and gas upstream activities is very important for the exploration and development of oil and gas fields. different and various laws and regulations deal with the investment in upstream operations. by reviewing these various laws and regulations, this research paper tries to discuss to what extent these laws and regulations have created legal confident for foreign investment up...

Wilkie (1999) proved a “theorem of the complement” which implies that in order to establish the o-minimality of an expansion of R with C∞ functions it suffices to obtain uniform (in the parameters) bounds on the number of connected components of quantifier free definable sets. He deduced that any expansion of R with a family of Pfaffian functions is o-minimal. We prove an effective version of W...

We develop a tractable two-country overlapping-generations model and show that cross-country differences in financial development can explain three recent empirical patterns of international capital flows: Financial capital flows from relatively poor to relatively rich countries, while foreign direct investment flows in the opposite direction; net capital flows go from poor to rich countries; d...

There has been criticism within the real estate professions that the lack of availability of good quality data has led actuarial professionals and academics to ignore real estate for modelling purposes. It has sometimes been asserted that this is one of the reasons for the decline in institutional investment in real estate, as asset allocation experts have ignored the asset class because of the...

editorial editorial l ong ago, in a political galaxy far away, i was educated at one of the world's elite universities. neither i, nor my middle-class parents, paid a penny in upfront fees for this privilege. in fact, the state—or more precisely my local municipality—paid me a substantial 'maintenance grant' every term which covered my room in college, living expenses, books and other study ess...

This means that for all n ≥ 2, there exists no first-order sentence Fn in the language Ln = (+,−,×,=, 0, 1, In) satisfying the following property: for any real algebraic variety V of R, if we interpret the n-ary predicate In by membership to V then R |= Fn if and only if V is irreducible. Our proof will imply that irreducibility remains undefinable even if we add the exponential function to Ln....

Let us recall that Raphael Robinson’s Arithmetic Q is an axiom system that differs from Peano Arithmetic essentially by containing no Induction axioms [13, 18]. We will generalize the semantictableaux version of the Second Incompleteness Theorem almost to the level of System Q. We will prove that there exists a single rather long Π1 sentence, valid in the standard model of the Natural Numbers a...
