Yanomamo - Essay Example The Yanomamo â€Å"foot-people† are spread out in about 125 villages scattered far and wide (Chagnon, 1983). Yanomamo is essentially a kin-based foraging and horticultural society. Kinship is a basic human trait. It is an important component that drives social behavior in every culture around the world. So also among the Yanomamo. Their social and political life is wholly controlled by kinship relationships (Chagnon, 1983). The Yanomamo communities live in small settlements or villages numbering 363 having 30 – 90 residents each, but sometimes reaching 200 or more (Hames, 1995). According to Chagnon (1974), larger the village size more intense their warfare. The people (numbering about 30 to 200) grouped by families live in one large circular communal dwelling, called a Shabono, having an open-air central plaza. Such an area of residence helps create strong bondsamong the people living there. Social organization of the Yanomamo based on kinship The people of the Yanomam o tribe classify themselves into two groupings - sibs (that is, clans) or lineages, both of which are formed based on kinship ties (Kensinger, 1996). Sib members trace their descent through their father from a named ancestor, â€Å"†¦.are dispersed throughout many villages and provide hospitality and safety for visiting kin.† (Kensinger, 1996).... As lineages are generally formed to promote the political ambitions of actual or wannabe leaders, they reflect the oscillations in political power. Usually disputes over leadership within lineages leads to village fissioning, and thereby to the scattering and even destruction of lineages. Yanomamo marriages The marriage exchange system of the Yanomamo people is generally based on kinship. It follows 4 main principles namely, lineage exogamy, bilateral cross cousin marriage, village endogamy, and polygyny. The Yanomamo society is exogamous and persons from the same localized lineage are prohibited from marrying. The members jointly take part in the selection of marriage partners for their children from within the allied lineage groups. The marriage system builds regular relationship between pairs of lineage groups who commonly intermarry through a system of bilateral cross cousin marriage (www.umanitoba.ca). A moiety system is created by such intermarriages when the intermarrying unit s co-reside in the same village. The co-settlement of intermarrying lineages is an example of village endogamy .Although under such a marriage system the Yanomamo lineages have collective rights to marry off their women and claim wives in exchange, they are not vested with the rights of administering joint assets such as land (www.umanitoba.ca). The practice of polygyny by the Yanomamo is exemplified by the fact that the men of the tribe commonly marry more than one wife. Polygyny among the Yanomamo is typically associated with the men’s rank or other achievements (Chagnon, 1983). Yanomamo political system The Yanomamo political system is not centralized which is because the community does

Lab 5 - Essay Example However, when the value of frequency was upped to 100, as in image 5, the amplitude of spectrum obtained was more distantly spaced when compared to those previous images with frequencies 5 and 50. Overall, the experiment proves differences/ changes in wavelength when frequencies are altered. In addition, the experiment Fourier offers better insight regarding waves. The images highlighted above are those of frequency wavelength cycles of 20.5, 60 and 100 that are found in the direction of X. Proportional to the frequency value/ strength applied the 2 dots found on the right portion of the images are variously spaced. This is seen the three images 7, 8 and 9 where images 8 and 9 which have superior frequencies exhibit greater spacing between the two dots that image 7 that has frequency 20.5. Image 9 has the greatest spacing therefore, as is clearly seen. This test demonstrates that waves are not found in the direction of Y but are situated along the X direction. The images shown have two spikes divided by the Fourier transform and the image and are exhibited as two different frequencies. As observed in image 10, there exist spikes frequencies which are low at 5.5. In image 11, spikes are of high frequency, at 30.5 with two waves above 0. The first of these waves above 0 is parallel to the low waves of frequency at 5.5 and the second one also parallel but to the waves of frequencies that are high at 30.5. Moreover, the spikes on the positive section resemble mirror images of those on the negative part as observed in the images 11, 13, 15. Image 13 and 12 additionally depict the same outcome as above when their values of N1 is 5.5 and that of N2 is 70.5. This implies simply that more brightness is obtained with increase in frequency. Contrarily, image 14 and image 15 with N1 being 20 and N2 at 22 do not result in frequencies that are good as the waves move and stop repeatedly (as observable in the images). To counteract this
