The Campus has the potential to be polluted by primary pollutants such as Particulate Matter (PM 10) and NO2. The results of monitoring ambient air quality by the DIY Provincial Environment Agency for parameters PM 10 and NO2 at several points representing the campus in Yogyakarta City showed that there was a significant increase in the concentration of NO2 and PM 10. This study aimed to determine the potential risk of ambient air pollution to human health especially high-risk population in university X. Methods: The type of study used observational analytic research. The collected samples were 6 samples of air pollutants from 3 station sampling site and subject sampling technique used purposive sampling with 32 respondents based on inclusion criteria were activities around the research location, a minimum work period of 1 year that consist of 22 parking attendants and 10 security guards. Results: Health complaints often suffered by respondents, namely chest pain by 29%, shortness of breath 32.3% and limb movements disorders 9.7%. The concentration of PM 10 and NO2 was found to be highest at the Station II (west parking basketball court) from 10:00 to 11:00 in the morning. The average concentration of PM 10 and NO2 was 152.67 µg /m3 and 45.83 µg /m3 respectively. Conclusion: PM 10 has exceeded the guideline standard of ambient air quality because of the vehicles activity. Hence, the potential risk to human strongly associated with long-term PM 10 exposure likely respiratory tract. The regulation needed to control air pollution through environmental monitoring, use the self-protection equipment, and routine medical checkup to the worker on campus.

The results of the study show a long-run equilibrium association among economic growth and the selected variables. Furthermore, there is a positive relationship between budget deficit, inflation, and economic growth, for the period under study for BRICS countries. Lastly, the results support the view that there is bi-directional linkage from budget deficit to economic growth and vice versa.

The aim of this research was to examine the determinants of private fixed investment in South Africa by employing the Johansen cointegration technique and the vector error correction model (VECM) analysis. Based on the literature survey it appears that the previous studies mainly focused on private investment in manufacturing and infrastructure sectors therefore this is envisaged to add knowledge to a body of economics literature in this area by focusing more on private fixed investment and its determinants in South Africa. The study concludes that for the period under investigation GDP has the positive sign as expected. This suggests that in the long run it impact positively on private fixed investment. The findings of the study also confirmed that tax rate is a complementary to private fixed investment. ...

The determinants of private fixed investment on this study include gross domestic product (GDP), real interest rate, real exchange rate and general tax rate. The aim of this study was to investigate the determinants of private fixed investment in South Africa by employing the Johansen cointegration technique and the VECM analysis. Based on the literature survey it appears that the previous studies mainly focused on private investment in manufacturing and infrastructure sectors therefore this is envisaged to add knowledge to a body of economics literature in this area by focusing more on private fixed investment and its determinants in South Africa. The study concludes that for the period under investigation GDP has the positive sign as expected. This suggests that as it has a positive impact on private fixed investment in the long run. The findings of the study also confirmed that tax rate is a complementary to private fixed investment. Similarly, the real exchange rate coefficient was negative as expected which suggests that the depreciation of the currency stimulates the growth of private fixed investment in South Africa. It is apparent that even the best economic model cannot achieve the expected outcomes immediately but these results encourage the study to believe that the South African monetary policy on exchange rate complements private fixed investment. Therefore, the study proposes that both even though both growth and general tax rate are difficult to accomplish simultaneously, they should be used to promote the flow of private fixed investment in South Africa.
