كثر الحديث منذ نهاية ثمانينات القرن الماضي عن الأزمة التي يمر بها حقل التنمية السياسية، بعد إخفاق النظريات الراديكالية ومن قبلها نظريات التحديث، في تقديم نظريات قادرة على فهم وتفسير التغيرات التي تمر بها مجتمعات العالم النامي، وعدم بروز أية بدائل أخرى قادرة على تجاوز تلك الإخفاقات.

In the molecule of the title compound, C17H16N2OS, the almost planar methylsulfanylquinazoline group [the methyl C atom deviates by 0.032 (2) A˚ from the plane through the ring system] forms an interplanar angle of 76.26 (4) with the plane of the phenyl group. An intramolecular O—H…N hydrogen bond is present between the quinazoline and hydroxy groups. In the crystal, molecules are stacked along the b-axis direction.

In the title compound, C22H28N2, the dihedral angle between the planes of the phenyl ring and the dihydroquinazoline ring system (r.m.s. deviation = 0.030 A˚ ) is 24.95 (7) and both n-butane chains assume all-trans conformations. In the crystal, N—H…N hydrogen bonds link the molecules into C(4) chains propagating in the [001] direction.

The main motive of this study is to discuss the foreign direct investment in Pakistan and the source from where foreign investment in the flow field is wide use of sources is to be discussed, In addition, here the purpose is to be discussed the reasons how to invest in Pakistan. There are many opportunities for the local and the international investors to come and invest in Pakistan in the different sectors like in Petroleum, Telecom, Powers, Textile, Ports and Agriculture sectors. These are the main sectors that are waiting for the investors to come and invest in these sectors.
