Simultaneously, the background operation of digital systems in routines of daily life increasingly obscures the materiality and meaning of technologically induced change. Computational architectures of algorithmic governance prevail across a vast and differentiated range of institutional settings and organizational practices. Car assembly plants, warehousing, shipping ports, sensor cities, agriculture, government agencies, university campuses. These are just some of the infrastructural sites overseen by software operations designed to extract value, coordinate practices and manage populations in real-time. To analytically grasp the emerging transformations requires media and cultural studies to inquire into the epochal changes taking place with the proliferation of digital media technologies. While in many ways the digital turn has long been in process, its cultural features and effects are far from even or comprehensively known.

A Twa hunter-gatherer in Uganda climbing a tree to gather honey. Nathaniel Dominy Early Human Ancestors May Have Walked AND Climbed for a Living Africa 31 December The results of recently conducted field studies on modern human groups in the Philippines and Africa are suggesting that humans, among the primates, are not so unique to walking upright as previously thought. The findings have implications for some of our earliest possible ancestors, including the 3. Associate professor of anthropology Nathaniel Dominy of Dartmouth College, along with colleagues Vivek Venkataraman and Thomas Kraft, compared African Twa hunter-gatherers to agriculturalists living nearby, the Bakiga, in Uganda.
Fourth, archaeological dating methods are based on evolutionary assumptions. When archaeologists investigate the site of an ancient city, they dig a trench and often find layers of .

Overview[ edit ] Although testing can determine the correctness of software under the assumption of some specific hypotheses see hierarchy of testing difficulty below , testing cannot identify all the defects within software. These oracles may include but are not limited to specifications, contracts ,  comparable products, past versions of the same product, inferences about intended or expected purpose, user or customer expectations, relevant standards, applicable laws, or other criteria.
A primary purpose of testing is to detect software failures so that defects may be discovered and corrected.
This course advances the ability of students to think algebraically, taking them from middle school work with variables and linear equations to the exploration of non-linear function types and more advanced calculations with variable expressions.
At higher temperatures, CO 2 has poor solubility in water, which means there is less CO 2 available for the photosynthetic reactions. The enrichment of bone 13 C also implies that excreted material is depleted in 13 C relative to the diet. This increase in 14 C concentration almost exactly cancels out the decrease caused by the upwelling of water containing old, and hence 14 C depleted, carbon from the deep ocean, so that direct measurements of 14 C radiation are similar to measurements for the rest of the biosphere.
Correcting for isotopic fractionation, as is done for all radiocarbon dates to allow comparison between results from different parts of the biosphere, gives an apparent age of about years for ocean surface water. The deepest parts of the ocean mix very slowly with the surface waters, and the mixing is uneven. The main mechanism that brings deep water to the surface is upwelling, which is more common in regions closer to the equator. Upwelling is also influenced by factors such as the topography of the local ocean bottom and coastlines, the climate, and wind patterns.
Overall, the mixing of deep and surface waters takes far longer than the mixing of atmospheric CO 2 with the surface waters, and as a result water from some deep ocean areas has an apparent radiocarbon age of several thousand years. Upwelling mixes this “old” water with the surface water, giving the surface water an apparent age of about several hundred years after correcting for fractionation.
This is probably because the greater surface area of ocean in the southern hemisphere means that there is more carbon exchanged between the ocean and the atmosphere than in the north.

It sounds really cool! This has an immediate impact of a collaborative project that my Digital Press at the University of North Dakota is working on that looks to publish a group of 3D models of limestone and terracotta figurings from the site of Athienou on Cyprus. The challenges associated with disseminating 3D images and models are relatively familiar to anyone who has explored the recent Gabii project or like me was unable to explore Digital Karnak.
The medium through which a project presents a dynamic 3D model is part of the message and the limits of the various interfaces and technology directly impacts the way in which the model functions.

Being awarded a fellowship to attend the seminar, which was jointly funded by the Andrew W. Mellon Foundation and the National Endowment for the Humanities, enabled me to take the time to read deeply in the literature of the profession, where I discovered that the failings I had been seeing in American archival institutions were not primarily a consequence of bad management, but of the fact that the best methods of the profession were inadequate to the task at hand.
Since , I have not pursued this research directly and the work has remained dormant. I have spoken about it publicly from time to time, but have not forced others or myself to deal with its conclusions. Increasingly I have felt that this is irresponsible of me, and am glad to be bringing it out for public scrutiny at this time.
In the process, the first four chapters have been substantially rewritten, but the underlying structure of the argument, and its conclusions, have not been affected. Although references throughout the text were updated to reflect recent literature, the modest amendments and refinements of archival methods and practices proposed during the past three years have not required me fundamentally to revise my premises. The first four essays address the four fundamental activities involved in the management of the physical record:

Dating refers to the archaeological tool to date artefacts and sites, and to properly construct history. All methods can be classified into two basic categories: Based on a discipline of geology called stratigraphy, rock layers are used to decipher the sequence of historical geological events. Relative techniques can determine the sequence of events but not the precise date of an event, making these methods unreliable. These methods are based on calculating the date of artefacts in a more precise way using different attributes of materials.
Chronological dating, or simply dating, is the process of attributing to an object or event a date in the past, allowing such object or event to be located in a previously established localhost:81 usually requires what is commonly known as a “dating method”. Several dating methods exist, depending on different criteria and techniques, and some very well known examples of disciplines using.
Love-hungry teenagers and archaeologists agree: But while the difficulties of single life may be intractable, the challenge of determining the age of prehistoric artifacts and fossils is greatly aided by measuring certain radioactive isotopes. Until this century, relative dating was the only technique for identifying the age of a truly ancient object.
By examining the object’s relation to layers of deposits in the area, and by comparing the object to others found at the site, archaeologists can estimate when the object arrived at the site. Though still heavily used, relative dating is now augmented by several modern dating techniques. Radiocarbon dating involves determining the age of an ancient fossil or specimen by measuring its carbon content.

The occasion of dramatically increased interaction with other cultures seemed to require a convenient summary of Japanese aesthetic principles, and Japanese art historians and archaeologists began to construct methodologies to categorize and assess a vast body of material ranging from Neolithic pottery to wood-block prints. Formulated in part from contemporary scholarly assessments and in part from the syntheses of enthusiastic generalists, these theories on the characteristics of Japanese culture and, more specifically, Japanese art not unexpectedly bore the prejudices and tastes of the times.
There was, for example, a tendency to cast the court art of the Heian period — as the apex of Japanese artistic achievement. The aesthetic preference for refinement, for images subtly imbued with metaphoric meaning, reflected the sublimely nuanced court mores that permitted only oblique reference to emotion and valued suggestion over bold declaration.
Furthermore, when you consider that many archaeological sites will contain numerous types of artifacts that permit the use of multiple dating methodologies, a modern archaeologist can often employ cross-dating methodologies which can allow for extremely accurate .
