fast food research paper
If one were to count the rituals associated with gourmet and fast food eating, surely a comparison would make the latter seem virtually ritual-less. Since few rituals exist for fast food dining, few must be learned, and few are in place to slow down the dining process. The plastic and chrome environment structures behavior and varies little from one fast food place to another: self-serve counters, plastic forks, formica tables and minimal social interaction—no waitresses, no busboys, no tips, no talk. Fast foods are fast, and dining is basically "gobble and go." So, although the rituals associated with such a spartan activity do exist, they are scarcely noticeable and only barely inhibit the flow of traffic in everyday life.

Adolescent fathers must reconcile the contradictory roles of both adolescence and fatherhood. As adolescents these young men seek to establish their own identities in personal and professional realms and resolve vocational-educational decisions and often conflictual peer and familial relationships. Cognitively, increases in their fund of knowledge and capacity for abstract reasoning allow them to begin thinking critically about their multiple roles as students, employees, friends, boyfriends, athletes, sons, and brothers. Cognitive reformulations of values, attitudes, and moral judgments would also be expected. Adolescent fathers must reevaluate their identity as adolescents in light of their new roles as parents and perhaps as partners in heterosexual relationships.

This Tertiary volcanic massif lies south of Mont Dore and is connected with it by a basaltic plateau. It forms the most prominent of the Pliocene volcanoes, and it also shows much dissection, so that the structure and succession of eruptive events can be determined. Its diameter is from 60 to 80 kilometers, and its mass about ten times that of Mont Dore. As in the latter case there are many elevated peaks, the highest of which, the Plombdu-Cantal, rises 1858 meters. These are all erosion peaks of parts of older eruptions, only one -- the Puy de Griou -- representing a late, though not the latest, eruption from the center of the volcano, but even it does not show the original height of the mountain.

The succession of eruptive events here is of similar character to that of Mont Dore, the volcano resting upon an old erosion floor of gneiss upon which were locally deposited beds of Oligocene sediments, which are especially well shown on the southwest. Through these came, first, eruptions of older basalt (5) (not positively known, though suspected, at Mont Dore) and this was followed by eruptions of acid trachytes and phonolites with trachytic tuffs, still of Miocene age (6). These locally rest upon the gneiss, or upon the Oligocene sediments, and still again, in one part of the section, upon the older basalts, showing that they succeeded these.

Both sinks and calderas are known which were formed by past volcanic activities in a region not subject to such disturbances at present. An example of an older sink is Crater Lake, Oregon. This occupies the site of a former volcano, which has been named Mount Mazama and the summit of which has collapsed. From this summit glaciers descended probably during the Pleistocene glacial period, which scoured and polished the sides of the volcano, as is shown by the marks still remaining on the outer slopes of the lake rim. Thus the collapse of the mountain summit is shown to have been a recent one, and appears to have followed upon an extensive outpouring of and by the fact that around their margins are extensive deposits of scoriæ and even of small volcanic bombs together with the fragments of shale and sandstone blown from the craters.

What is the shape of the magma reservoir feeding a volcano, and how did it become emplaced? What is the relation between volcanism and the enormous massifs of plutonic rocks that cover large areas on the continents? How did they become emplaced? These tantalizing questions are not so easy to answer. As a matter of fact, they are fundamental problems. As in nearly all fundamental problems we must frankly admit that an attempt at an answer only leads to the expression of fundamental uncertainty. Ask an astronomer how the solar system -- including the earth and the moon -- came into being.

Beyond doubt the plutonic and volcanic rocks accessible to observation at the surface belong to two main types. Plutonic intrusive bodies are dominantly of granitic composition, whereas the dominant extrusive volcanic rock is of basaltic composition. According to Barth about 95 percent by volume of the intrusive rocks are granitic, and about 98 percent of the extrusive rocks are basaltic. Rocks of intermediate chemical composition are comparatively rare. A further striking fact is that basaltic rocks have been found on oceanic islands as well as on the continents, where in all geological periods they penetrated the sialic rocks and their sedimentary cover in vast quantities.

Fissure-eruptions on the flank of a volcano display a curious phenomenon. A series of craters open along the fissure during an eruption. The uppermost craters are just deep vents originated from mere explosive action. Proceeding downwards the next crater rims are built up of small explosive products called lapilli. Then follow craters surrounded by bigger ejectamenta like volcanic bombs. Finally, lava flows were produced from the lowermost crater. The explanation of this striking arrangement of craters displaying an eruptive sequence which runs from explosive to effusive. A similar phenomenon was seen during the 1926 eruption of the Batur volcano in the island Bali. The surface of a lava-flow cools and solidifies rather rapidly to form a hard stony crust. If this crust breaks at the snout of the flow and the still molten inner part continues further down the slope the cooled crust is emptied of its contents.
research paper on racial profiling
In racial mixtures dating back to a distant past, as in the present instance, the initial combinations of traits do not appear; as a result of the mixing, there form various combinations of these traits, which are related to the original components. Moreover, it is necessary to take into account the phylogenetic changes of the type, the nature of which is very little known thus far. Nevertheless, the possibility of coming closer to a solution by means of indirect data is not to be excluded. Thus, it may be assumed with great probability that the basic Mongoloid type of the Neolithic population of western Cis-Baykalia was not identical with the Mongoloid type of Trans-Baykalia, the latter being known from the skulls of the Glazkovo period.

But even these traits do not fit properly into the scheme of the Japanese authors. In spite of their outward coherence, the theories of Hasebe, Matsumura, and Matsumoto arouse serious doubts when the material is critically examined. Already Buxton, who had access to the materials and made his observations in Japan, pointed to the abstract nature and a certain arbitrariness of the types distinguished by the Japanese anthropologists. It is evident that an analysis of a physical make-up which proceeds basically from variations in stature and cranial index is totally inadequate for the differentiation of racial types.
