The pulse compression scheme implemented on the Imaging Wind and Rain Air-borne Profiler (IWRAP) is described. Developed at the UMASS Microwave Remote Sensing Laboratory (MIRSL), IWRAP is a dual-band (C and Ku) conically scanning Doppler scatterometer designed to map the atmospheric boundary layer wind fields, ocean surface wind fields, and precipitation within tropical cyclones. IWRAP has previously been deployed using a pulsed transmit waveform with a peak transmit power of 80 watts. This limits the average transmit power and sensitivity for the system which affects the more distant range gates (especially at Ku-band). As a result, IWRAP could operate only at lower altitudes (approx. 5000 ft) causing safety concerns and limiting the missions for which it can be deployed. Increasing sensitivity was achieved by converting IWRAP to a pulse compression radar system. Pulse compression is a technique that combines the increased energy of a longer pulse with the high resolution of a short pulse by implementing a frequency modulated (FM) “chirped” transmit waveform. This method requires advanced signal processing, in which the received signal is passed through a filter to compress the pulse on the receiving end. A system with various chirp/filtering schemes as well as a new control system which UMASS has recently developed will be discussed in this thesis.

The arroyo toad (Anaxyrus californicus) is a federally endangered species found on Fort Hunter Liggett, Monterey County, California. The species was discovered in 1996 and was determined to occupy 26.7 km of the San Antonio River from approximately 2.4 km northwest of the San Antonio Mission de Padua, to the river delta above the San Antonio Reservoir. The construction of the San Antonio Reservoir dam in 1963 isolated this northern population of arroyo toads. Through time, the Fort Hunter Liggett landscape has changed drastically. The land was heavily grazed by cattle until 1991, which considerably reduced vegetation in riparian areas. Military training following acquisition of the land in 1940 far exceeded current allowable training. Fire was used extensively to reduce unfavorable vegetation, and as a result, extreme tree loss occurred through the ranges. Today cattle grazing is prohibited and military activity is restricted from riparian corridors. While riparian vegetation continues to recover in the San Antonio River, habitat for breeding arroyo toads has become less suitable. To improve conservation efforts and management of this endangered species, I have provided a thorough assessment of the life history of arroyo toads specific to Fort Hunter Liggett and identified the status and current threats to the population on the installation. I have also prepared a habitat assessment of the San Antonio River in the arroyo toad range, quantified habitat conversion, and identified areas that may no longer provide suitable breeding habitat for the species. The research conducted for this report is preliminary to restoration efforts that are inevitable to ensure recovery of the endangered species at Fort Hunter Liggett.

No / Current models of the Mesolithic settlement and mobility systems of northern England have largely resulted in a highly constrained view of the spatial use of the changing postglacial landscape. The ethnography of northern hemisphere hunter-gatherers in North America is at odds with such interpretations. It can be shown that in mid and high latitude forested environments mobile hunter-gatherers (a) use large areas on a seasonal basis and (b) engage in long distance logistic mobility. The application of these observations to the Mesolithic of northern England leads to reappraisal of both the spatial scope of regional settlement systems, and the degree to which upland and coastal environments are employed in the subsistence¿settlement strategy. The results are improved appreciation for the process of colonization and the ¿filling in¿ of the region as well as a more dynamic view of regional Mesolithic mobility systems, both of which have important implications for the role of sites such as Star Carr in regional context.

In many cases in the past fish bones recovered during archaeological excavations at Upper Palaeolithic sites were often assumed to result from human activity without any consideration for alternate accumulation processes. Many of these assemblages had not been analysed in a scientifically rigorous manner, with some receiving no consideration at all. A review of current evidence and results of new analyses indicate that salmonids (salmon and trout) are the most frequently recorded fish at the European Palaeolithic cave sites. Two potential accumulation agents for fish remains were explored: brown bears (Ursus arctos) and eagle owls (Bubo bubo). Controlled feeding experiments integrated with ecological studies indicate that salmonid remains survive the digestive systems of both species and result in distinctive patterning in assemblage characteristics. Post-depositional taphonomic processes, such as trampling, also produce distinct taphonomic signatures and are an agent of differential inter-species preservation. A thorough consideration of depositional and post-depositional processes of archaeological assemblages in central Italy (Grotta di Pozzo, Maritza, La Punta and Ortucchio) and Spain (El Juyo, Altamira, Salitre, Castillo and Rascaño) shows that the fish remains from these sites result from human activity. The overrepresentation of cranial elements at the Italian sites suggest that fish were processed by removing the head to perhaps smoke or dry before transportation to other locations for consumption. This research lead to improved methods of analysis, and thus enhanced understanding of the role of fishing and fish consumption in Upper Palaeolithic hunter-gatherer societies.

Ochre is a culturally significant material that is commonly recovered from archaeological sites. However, despite its ubiquity it has yet to realize its full interpretive potential as an artifact of archaeological inquiry, specifically in the context of geochemical characterization studies. Studies of this type, often referred to as ‘sourcing’ studies, involve the application of techniques in radiation physics to determine the elemental composition of artifacts and raw materials. These data are then used interpret patterns of behaviour in the procurement, movement, and trade of different artifact classes such as obsidian, chert, or ceramic. By comparison, geochemical characterization studies centred on ochre-related activities are fewer in number. This thesis consists of three case studies that developed methodological foundations for the geochemical study of ochre in regions of British Columbia and Ontario, Canada, respectively. Using instrumental neutron activation analysis and X-ray fluorescence, ochre from geologic outcrops and archaeological sites were analysed to determine their elemental composition. Multivariate statistical tests, including principal components and canonical discriminant analyses, were conducted to explore patterns and variability in ochre geochemistries. The results described in the following papers demonstrate the challenges and limitations for characterization studies of ochre, and present considerations for expanded research in these geographic regions. This thesis offers contributions to broader topics of discussion in archaeological sciences, such as the accurate and precise acquisition of geochemical data, the role of geologic scales and diagenetic processes on the chemistries of iron oxides, how to identify and interpret patterns in elemental data sets, and the utility and limitations of portable analytical technologies. This research has established important methodological foundations for the study of ochre in British Columbia and Ontario, and has demonstrated the potential for expanded analysis of materials from additional archaeological sites and geologic outcrops. This will enable the future interpretation and regional synthesis of patterns and networks of ochre-related activities, including quarrying and procurement, trade and exchange, and variability in use contexts. / Dissertation / Doctor of Philosophy (PhD)

In this dissertation, I investigate the nature of social relations on the northern Northwest Coast during the Late Middle Period (500 BC to AD 500) through the rubric of House Societies as defined by Levi-Strauss (1982). In House Societies, corporate groups hold estates and wealth that are transmitted from one generation to the next. Houses were, and still are, the fundamental organizing principle in Tsimshian society. In the 19th century, Houses were central to systems of property ownership and social ranking. The antiquity of this institution however, is not clear. In this study, I ask whether Houses existed in the past in the Prince Rupert area and if so, what implications they might have had on social and economic relations. To investigate this question, I excavated two house depressions at GbTo-77, a small village site in Prince Rupert Harbour and considered whether evidence existed for long-term investment in place, the transmission of dwellings across multiple generations, and for owned estates or resource locations. The results suggested that one house depression (house D) showed some evidence for house reconstruction and maintenance, but over a relatively short period of time, particularly in comparison to other locations across the Northwest Coast. A second house depression, however, may have been used intermittently, or for an even shorter period of time than house D; no evidence was found for continuity between occupations or long-term investment in architecture. Faunal remains from both house depressions were very small and could not be reliably used to infer differences in owned resource locations. As such, the results of this study indicate that the house depressions at GbTo-77 likely do not represent Houses. These results are significant because archaeologists have often assumed that the house depressions forming organized, rowed villages, such as GbTo-77, are the remnants of Houses or incipient Houses. I explored also how architectural, stratigraphic and faunal evidence at GbTo-77 compared with these data at four other village sites in Prince Rupert Harbour. Few other house depressions were excavated sufficiently in order to adequately compare architecture remains between villages. The comparison of faunal remains between village sites in Prince Rupert Harbour, however, showed that there may have been important differences between villages in terms of economic systems, particularly in terms of salmon abundance, when compared with other fish taxa. The most significant differences in abundance were observed within column, bulk and auger samples (equal volume samples), indicating the importance of using small mesh screens (<2.8 mm) in faunal analyses. These data suggest that villages may have exerted control over important resource locations. The extent to which this control, or ownership, might reflect differences between houses, rather than villages, is not entirely clear for the Late Middle Period villages. I also observed significant differences in terms of shellfish composition at each village site. Variability in local resources may relate primarily to the precise location of these villages within the harbour, but may also have implications for our understanding of pre-contact land tenure practices in Prince Rupert Harbour.

The aim of this student thesis is to achieve a translation of an excerpt of a previously untranslated book from English to Swedish. The translated material has been collected from the autobiographical book Kingdom of Fear by the author Hunter S. Thompson and consists partly of paratexts. The translation has been performed in accordance with a principle that was formed within the theoretical frames of Gideon Toury’s Descriptive Translation Studies. Accordingly, the discussion about the translation is based on the terms adequacy and acceptancy. The paper includes analyses of relevant aspects of the translated material, for example genre, paratext, and persona related problems. To illustrate the translation process, comments on the translation are also enclosed, which deal with solutions regarding grammatical and syntactical changes, imagery and cultural-specific expressions. / Syftet med detta examensarbete är att åstadkomma en översättning av ett utdrag från ett tidigare oöversatt verk från engelska till svenska. Det översatta materialet är hämtat från det autobiografiska verket Kingdom of Fear av författaren Hunter S. Thompson och består bland annat av paratexter. Översättningen har utförts efter en princip som formulerats inom de teoretiska ramarna för Gideon Tourys Descriptive Translation Studies. Därmed utgår diskussionen kring översättningen från termerna adekvans och acceptans. Arbetet innefattar analyser på relevanta aspekter av det översatta materialet, exempelvis genre, paratext och personaproblematik. För att åskådliggöra översättningsprocessen medföljer även översättningskommentarer som behandlar lösningar angående grammatiska och syntaktiska ändringar, bildspråk och kulturspecifika uttryck.
