Convergence zone

in the perseveration of sediment integrity and thus, provided the geologists with a natural clock to determine when the sediments were laid down using yearly resolution (Peterson and Haug 2005, 324). It has been argued that the rainfall record of Cariaco Basin cannot provide insight on the rainfall record of most Maya sites because of the distance between the locations: for example, the site at Tikal, Guatemala which is 2,700 kilometers away from the Cariaco Basin (Aimers 2011, 45). While this does questions the relevance, Peterson and Haug explain that Cariaco Basin’s rainfall is in fact applicable to Maya sites because both places experience a general pattern of seasonal rainfall as a result of being located in the intertropical convergence zone (Peterson and Haug 2005, 325). Using x-ray florescence, Peterson and Haug discovered a broad interval of low titanium levels in the sediments between 800 and 1000 A.D, which indicates the presence of drought and moreover, corresponds with the results of Hodell and his colleagues (Peterson and Haug 2005, 326). Then, using a micro x-ray florescence system, Peterson and Haug discovered a series of four distinct titanium minima, thus indicating multi-year droughts (Peterson and Haug 2005, 326). The sediments were then radiocarbon dated and revealed that the droughts occurred in 760, 810, 860 and 910 A.D-plus or minus thirty years due to the age of the sediments (Peterson and Haug 2005, 326). This discovery partially provides an…

Atmospheric Global Circulation is the movement of air caused by solar energy and the interaction of warm and cold air - this convergence forms cells or belts over the Earth’s surface. George Hadley (1685–1768) a British physicist and meteorologist, who first described this theory in 1753, did so using what is known as the Single-Cell Atmospheric Global Circulation Model or Hadley Cell (The Editors of Encyclopædia Britannica, 2007). Hadley’s Single-Cell theory failed to consider the Coriolis…

This class, though we spent the majority of time talking about innovation, both sustaining and disruptive, was at its heart a class about convergence. In layman’s terms, convergence is the coming together of two or more distinct entities or experiences. There are three main lenses through which we at convergence, technological, economic, and cultural. Technological convergence occurs when existing technologies come together in a way that inspires new use or creates new applications. An example…

& Deuze 2001). Essentially, network journalism is a new sub-genre of media, allowed to come about as a result of the internet and the massive number of users on it (Bardoel & Deuze 2001). Quite simply, this concept can be broken down into three core ways that it is changing popular culture. The first, according to the source, is that it has the potential to make the journalist as an intermediary force in democracy somewhat superfluous (Bardoel & Deuze 2001). This convergence of media, according…

information can spread through social media. Technological convergence provides us access to more things than we could ever imagine. With little effort we can check our bank accounts, stream Netflix, video chat with friends all over the world, and read a book on our phones. This is due to what Jenkins refers to as Convergence Culture. Convergence culture is defined as an era where old and new media collide and multiple forms of media merge together. One of Jenkins main focuses’ is on…

This lower budget means that small departments can put less officers and less vehicles on the roads. Having less officers means that the departments must break its jurisdiction into larger zones and may not be able to place more than one unit in each zone. This means that officers are further away from back up and response times may be longer than those experienced in the city. Rural departments are unlikely to afford specialized units meaning that bomb disposal, drug cases, and special victims…

through dramatization and rhetorical vision. “Rhetorical vison is considered to be construction of a groups world view”. Once engaged in the fantasy, the theme itself creates a cohesiveness within the group. He incorporated fantasy themes into his theory called symbolic convergence theory, which involves “sharing group fantasies that create symbolic…

to be found in the conventional, civilized world. The scenes that take place outside the Zone are painted in a condemning light. The home of the Stalker, the building and town in which he resides that is slowly exposed to the viewer in the beginning portion of the film, is depicted as an empty, hopeless place. The incentive for this portrayal is the origin of this place’s ruin. While the Zone represents a more organic decay, demonstrative of the inevitable continuation of life, this place is the…

nutrients and lack of diversity within the competition of space and lack of predators. Despite these favourable characteristics, certain limiting factors prevented the organisms from inhabiting the site. Perhaps the most crucial limiting factor was the substrate. Since barnacles secrete an adhesive onto solid rock to withstand high velocity waves and remain sessile, a porous substrate disabled the organism to effectively attach itself to its substrate. Another factor was the competition…

Since we are in a drought, the flow was very slow, 0.096 ft/sec, and the water depth was low, and anyone could easily walk through the water. The stream’s banks and bank stability were strong and intact. The channel gradient was low and not steep, and the sinuosity was meandering/braided. The embeddedness of the rocks in the stream was about 25%. There was quite an abundant amount of vegetation, the dominant plant species were conifer trees, deciduous trees, and herbaceous. The riparian zone was…
