Qualitative research paper - Essay Example important with respect to the African countries where the population living below the poverty line is more than fifty percent of the total population. The lacks of opportunity for strengthening the financial condition of the individuals have multiple implications on the social lives of individuals. The FDI helps in the inflow of money in the economic cycle resulting in the acceleration of the economic growth as well employment opportunities. The literature review section of the study covered various theories and models of FDI and growth of an economy. The determinants of FDI like cross border investment issues, collaborative ventures and various important issues to understand the determinants of FDI was discussed in the first section followed by the Growth Empirical Modeling where the Growth empirical approach, the Intertemporal Optimization approach and the Panel Data Analysis approach has been studied. The gaps of the models have been identified and argued in this section and the conceptual framework of the study is prepared. The main section of the paper is the chapter following Literature review. The factors determining FDI flows to Africa and threshold issues for the foreign investors have been studied here. The approaches identified for the determinants of FDI has been aggregate econometric analysis, survey appraisal of foreign investors’ opinion and econometric study at the industry level of the study. The study has been based on the Aggregate Econometric Approach. According to this approach the basic determinants of the inflow of FDI in a particular country or a region are dependent factors of the size and growth of market and openness of the country at the primary level and various other factors like host country investment environment, factor endowments, infrastructure and technology and country risk at the secondary level. The research methodology studies the variations in long-run rates of the economic growth across the countries by Levine and

Operational Amplifiers - Lab Report Example The slight difference in the measured and calculated values is because of the non-ideal character of an Op-Amp, the connecting wires etc. The moisture component present in the atmosphere, the wiring arrangement of the library, some High Tension (High Voltage) public supply electricity line going around the laboratory also affects the measurements. Sometimes if the connecting wires make a loop then the induction effect also comes in picture. Once again the non-ideal nature of electronic gadgets comes into picture. In fact the inherent resistive component of the power supply too causes some variations in the output parameters. The moisture present in the atmosphere or less than ideal nature of oscilloscope probes too causes variations. The ideal output voltage should be the product of the dc input signal and the amplifier's closed-loop voltage gain. However, the output voltage has an added error component. If the ideal value of output voltage is large with respect to the error component, then we can usually ignore the op amp characteristic that causes it. But if the error component is comparable to or even larger than the ideal value, we must try to minimize the error. The closed loop gain mainly depends upon the external resistors. Op amp characteristics that add error components to the dc output voltage are: When we disconnect the feedback loop (Resistor R), then it is no more 'closed loop gain' for the op amp. There is no negative feedback. And input voltages at oscilloscope terminals are different. The measured values are; Channel1: 3V Channel2: 14V Ans. 8. Now to get a gain of 6 in figure 5 (above), the calculated value of resistance R is; 6 = 1 + (R/10000) i.e. R = 60000-10000 = 50K Measured voltages : . . . . . .
