Managing The Nigerian Economy Through Fiscal Deficit, Umar Bala, Badamasi Salihu Uba, Adamu Yahuza Haruna

International Journal of Management, Finance and Accounting

This study examined how fiscal deficit, exchange rate, and inflation rate impacted the economic growth of the Nigerian economy from 1980 to 2019. The cointegration connection in the study was discovered using the autoregressive distributed lag (ARDL) bound test. The analysis found that, while inflation and the exchange rate have a positive and significant relationship with the Nigerian economy, the fiscal deficit has a negative but relatively insignificant effect on the country's GDP. The Nigerian government should stabilise the currency's external value and prevent it from falling in value in the short term. Such policies should be developed to encourage …

Local Labor Markets Exposure To Artificial Intelligence, Greg Call

Dissertations

As more evidence builds that artificial intelligence (AI) is a new general-purpose technology driving a fourth industrial revolution, scholars have begun to consider its potential impact on labor markets. The current debate among researchers is centered on whether AI will ultimately produce net new job gains or losses and what type of workers will benefit or be displaced. While no consensus has developed yet within the literature on AI’s predicted net employment impact, a majority of studies are forecasting that a skill-biased technological change will occur.

This exploratory study contributes to the current literature by operationalizing Webb’s objective patent-based AI …

Equity In The Math Classroom How Math Teachers Can Achieve Equity Despite District’S Budget, Tony Edward Kohanek

School of Education and Leadership Student Capstone Projects

American pedagogical theorist and teacher educator, Gloria Ladson-Billings, has done the research and shown how impactful the achievement gap is as it is “one of the most pressing education-policy challenges that the states are facing” (Ladson-Billings, 2006). What makes this issue such a problem is that students don’t even need to be in school for it to appear as noted by Andy Porter of Penn State’s GSE (Graduate School of Education). He states that by the time children reach the age of three or four, there’s already a one standard deviation achievement gap between white children and POC, people of …
