ضیاء محمد ضیاء(۱۹۲۸ء۔پ)کا اصل نام ضیا محمد اور تخلص ضیاؔ کرتے تھے۔ آپ کنجاہ سے متصل ایک بستی قاسم آباد ضلع گجرات میں پیدا ہوئے۔۔ ۱۹۵۳ء میں آپ نے سرکاری ملازمت اختیار کر لی اور گورنمنٹ ہائی سکول نمبرا پسرور میں بطور معلم السنہ شرقیہ تعینات ہوئے۔ اس کے بعد آپ مستقل طورپر پسرور میں اقامت پذیر ہو گئے۔(۷۶۲) آپ کے دوشعری مجموعے ’’نوائے شوق ‘‘اور ’’ارمغانِ عشق‘‘ شائع ہو چکے ہیں۔ ضیا اقبال کو روحانی مرشد اور فکری راہنما تسلیم کرتے ہیں۔انھیں غزل گوئی کے بجائے نظم نگاری پر زیادہ عبور حاصل ہے۔ قومی افکار، اخلاقی اقدار اور عشقِ حقیقی ان کی شاعری کا محور ہیں۔نمونہ کلام ملاحظہ ہو:
اے نقشِ گر ہستی ، اے صانع زیبائی
صنعت پہ تری حیراں ہے چشمِ تماشائی
خورشید و مہ و انجم آئینہ نما تیرے
مظہرِ تیری قدرت کا یہ گنبدِ مینائی
کثرت میں بھی دیکھا ہے جلوہ تری وحدت کا
ہے نقش دوئی باطل، حق ہے تری یکتائی

Foreign direct investment plays a key role in economic development of all countries. Because of its enormous importance, a large number of empirical studies has focused on finding out the factors determining foreign direct investment. Level of human capital development is one of the major factors influencing foreign inflows. However, earlier studies examining impact of human capital on foreign investment inflows has majorly used literacy rate, school enrolment and government spending on education as its proxies. This paper also examines the impact of human capital as determinant of foreign direct investment. Contrary to earlier empirical studies, it uses cognitive skills as proxy for human capital. Cognitive skills measure the quality of education instead of literacy rate or government spending on education as proxy for human capital. Results indicate that human capital has significant positive effect on foreign direct investment for sample countries. This result is robust to disaggregated data for developed and developing countries. Other factors that determine foreign direct investment inflows are inflation, capital account openness, trade account openness and real income. Based on empirical results, it is recommended that the relevant authorities must make human capital as part and parcel of strategies aimed at augmenting economic growth in the country. There is also a lesson for a developing country like Pakistan to focus more on quality of education instead of school enrolment or education spending for attracting foreign direct investment to boost economic activity (J.E.L Classification Codes: O4, O15, P22).
The potential for breeding Gossypium hirsutum L. for water stress tolerance was investigated in the present studies. For this purpose, a sample of 50 cotton cultivars was screened out in greenhouse at 20% field capacity. Water stress was applied for four weeks. The performance of 50 cultivars was compared using data on shoot and root lengths, relative water content, excised leaf water loss and relative cell injury in absolute terms, calculating drought susceptibility indices (DSI) and through biplot analysis. Cultivars showing low DSI were selected as water stress tolerant, and cultivars showing highest DSI were identified as susceptible to water stress. Biplot analysis of germplasm under study revealed genetic divergence for water stress tolerance. On the basis of these three measures, CIM-496, 149F, DPL-26, BOU-1724 and B-557 were found tolerant to moisture stress, whilst FH-1000, NF-801-2-37, MNH-129 and H-499 exhibited susceptibility to water stress. The remaining cultivars revealed variable responses to water stress when these three measures were studied. Many researchers had emphasized on root length and used it as reliable indicator of drought tolerance. Therefore data on root length in the present plant material under moistures deficit conditions was used to calculate broad sense heritability (40%), which seemed to be encouraging for plant breeders. Molecular characterization of selected cotton cultivars was done using simple sequence repeat (SSR) markers. Analysis of molecular data did not reveal significant differences in genome, indicating relatedness among the brief sample of germplasm. Results of screening revealed that working variability among germplasm was present and controlled by significant genetic component, which may be exploited through hybridization. Therefore, F1 crosses were developed in the field keeping stress tolerant cultivars as lines and susceptible as testers using line × tester technique. Genetic material was field-planted and 50% moisture stress was applied to examine responses measuring plant height, seed cotton yield, number of bolls, boll weight, lint percentage and fibre traits. The analysis of F1 and parental data revealed the presence of both additive and non additive genes controlling variation under both the water regimes (normal and 50% stress). However, non additive genetic effects were more pronounced under water stress, suggesting the presence of low heritability for all the traits. Lines and interaction term contributed more to expression of seed cotton yield, number of bolls and boll weight, whilst lint percentage and fibre length were largely determined by the lines. Tester parents significantly contributed to fibre fineness. Non additive variation for fibre and yield related traits suggests possibility of using this material for hybrid development, and best varietal combinations were identified for exploitation in drought hit areas.
