Economic Demography ( project Assignment) - Term Paper Example Also it examines the limitations that may arrive due to considering only education as the factor of the wage inequality. Furthermore, it takes into account the other factors that may result in the different wages of people. In this paper I would try to establish the fact that education is a determinant of wage inequalities. For the purpose of my research I’ve collected a data set which has pre tax wages and salary. Against this data set I’ve taken a data set that records the highest grade attended by the individuals. These two data sets are taken specifically to test my hypothesis correctly. For the purpose of the analysis I have also used many literature reviews. The data set that has been used for the education records the highest grade of the individual. This data set has been designed in such a way that it captures the number of years of education for the individuals. The range is from 0 years spent in education to 8 years spent after college in education. Further, it shows that on average in the US, people drop out of the college after their second years. The data set that used for the purpose of the analysis of the income is the personal wage and monthly income of all the individuals in the United States. The range for this data set is not specified which means that it applies to all individual cases. From the data sets that were used, the interesting deduction that one can make is that the correlation of the wage or the salary income and the highest grade attended by the individuals is very high that is -0.8 for 18,447,324 individual cases. (IPUMS samples) The standard errors that have been recorded here are approximately equal to zero which means that the T-static value is 0.00. This ensures that the coefficient of the correlation is statistically significant no matter what confidence level is taken. This is because the null hypothesis (the correlation coefficient equals zero) can be rejected at all levels of

Persian Wars - Essay Example However, the spark igniting this into war with the Persians was a revolt of the Ionian Greeks. The Ionian Greeks had peacefully submitted to Persian rule and lived under Persian appointed Greek tyrants since the time of Cyrus the Great. Then in 5l0 B.C.E., the Ionian Greeks raised the standard of revolt and drove their tyrants out. Realizing they needed help against the mighty Great King, Darius, they appealed to their cousins across the Aegean for aid. Sparta, ever wary of a Helot revolt, refused to help. However, Athens and another city-state, Eretria, did send ships and troops who joined the Ionians, marched inland, and burned the provincial capital, Sardis, to the ground. After a Persian force defeated the Greeks as they were returning from Sardis, the Ionian Greeks decided to stake everything on a naval battle at Lade (494 B.C.E.). Therefore, it is the Ionian revolt that has sparked the Persian Wars. (Cited from FC23A: Persian Wars) The first Persian invasion of Greece, during t he Persian Wars, began in 492 BC, and ended with the decisive Athenian victory at the Battle of Marathon in 490 BC. The invasion, consisting of two distinct campaigns, was ordered by the Persian king Darius I primarily in order to punish the city-states of Athens and Eretria. These cities had supported the cities of Iona during their revolt against Persian rule, thus incurring the wrath of Darius. Darius also saw the opportunity to extend his empire into Europe, and to secure its western frontier. The first campaign in 492 BC, led by Mardonius, re-subjugated Thrace and forced Macedon to become a client kingdom of Persia. However, further progress was prevented when Mardonius’ fleet was wrecked in a storm off the coast of Mount Athos. The following year, having demonstrated his intentions, Darius sent ambassadors to all parts of Greece, demanding their submission. He received it from almost all of them, excepting Athens and Sparta, both of whom executed the ambassadors. With A thens still defiant, and Sparta now effectively at war with him, Darius ordered a further military campaign for the following year. The second campaign, in 490 BC, was under the command of Datis and Artaphernes. The expedition headed first to the island Naxos, which it captured and burnt. It then island-hopped between the rest of the Cycladic Islands, annexing each into the Persian Empire. Reaching Greece, the expedition landed at Eretria, which it besieged, and after a brief time, captured. Eretria was razed and its citizens enslaved. Finally, the task force headed to Attica, landing at Marathon, en route for Athens. There, it was met by a smaller Athenian army, which nevertheless proceeded to win a remarkable victory at the Battle of Marathon This defeat prevented the successful conclusion of the campaign, and the task force returned to Asia. Nevertheless, the expedition had fulfilled most of its aims, punishing Naxos and Eretria, and bringing much of the Aegean under Persian rule . The unfinished business from this campaign led Darius to prepare for a much larger invasion of Greece, to firmly subjugate it, and to punish Athens and Sparta. However, internal strife within the empire delayed this expedition, and Darius then died of old age. It was thus left to his son Xerxes I to lead the second Persian invasion of Greece, beginning in 480 BC. The second Persian invasion of Greece (480-479 BC) occurred during the Greco-Persian Wars, as King Xerxes I of Persia sought to
