Kenny, John. "The Chicano Mural Movement of the Southwest: Populist Public Art and Chicano Political Activism." ScholarWorks@UNO, 2006. http://scholarworks.uno.edu/td/492.
Full textAbstract:
This work examines an art movement that was a direct outgrowth of a populist civil rights movement of the late 1960’s in the Southwest United States. This art, the Chicano Murals created as part of el Movimiento in San Diego, California was intended primarily as a didactic communication medium to reach into the barrios and marginalized neighborhoods for the primary purpose of carrying a resistance message to the semiliterate mestizo population within. Its secondary purpose was to bring a message from within these minority neighborhoods outward to the privileged elite, both Anglo and Hispanic, that within the confines of the barrio there exists a culture and heritage that has value. The Chicano Murals were ubiquitous throughout the southwest United States with concentration of the art in those areas adjacent to the Mexican border. This work examines some of the murals, and the politics associated with their creation principally in San Diego, California, and some activities in Los Angeles, and Santa Fe, New Mexico. This dissertation posits that it has been well established that art in public space is often a contentious matter and when it also carries a contra message, as did the Chicano murals, it may be considered intrusive and abrasive. The social environment into which these murals were insinuated--the public sphere, the intellectual territory of high art and the elite system of private and government cultural patronage, are examined in the context of their effect upon the mural content and conversely, the effects of these murals upon diversity in the high art and museology of the United States.

Full textAbstract:
This research examines and compares the distributions of archaeological sites and materials in order to investigate native settlement patterns and resources use throughout 12,000 years of prehistory and protohistoric time within the Apalachicola/Lower Chattahoochee River valley of northwest Florida, southwest Georgia, and southeast Alabama. Geographic Information Systems (GIS) are used to map the distributions of sites from different time periods and to explore their relation to various environmental characteristics that are now available in digital format. I employ tools now available in GIS to examine several longstanding research questions and expand upon archaeological interpretations within this region, where the University of South Florida (USF) has an ongoing research program. The results of this work illustrate change through time and space as cultures begin to adapt to post-Pleistocene ecological change, develop food production and complex societies, and react to the appearance of European groups.

Marshman, Amy G. "Ancient Puebloan Human Effigy Vessels: An Examination of Iconography and Tradition." VCU Scholars Compass, 2016. http://scholarscompass.vcu.edu/etd/4174.
Full textAbstract:
This dissertation provides an iconographic interpretation of a group of Ancient Puebloan human effigy vessels and fragments from the American Southwest, dating to the Pueblo II period, c. 900 -1150 CE. Initially, this project focuses on Ancient Puebloan human effigy vessels from three specific collections; a single vessel in the collection of the National Museum of the American Indian in Washington, D.C., a human effigy vessel in the collection of the American Museum of Natural History in New York, and the so-called Putnam Human Effigy Jar from Chaco Canyon at the Peabody Museum of Archaeology and Ethnology at Harvard University. This study interprets these three vessels primarily as expressive sculptural forms, as opposed to ritual or utilitarian objects.
Stylistically and formally, these vessels are similar to several other human effigy vessels attributed to the Ancient Puebloan tradition. Two catalogs have been compiled for this study. Catalog A consists of Ancient Puebloan style human effigy. Catalog B presents comparable human effigy vessels created in a variety of ancient Southwestern styles, related to, but considered distinct from the Ancient Puebloan style. Formal and iconographic similarities between human effigy vessels in these cultures and the Ancient Puebloan culture suggest a shared cultural phenomenon, or, at the very least, is evidence of regional cultural relationships. Similar human effigy vessels can also be found outside of the ancient Greater Southwest in Precolumbian cultures. Of particular scholarly interest is the nature of the perceived relationship between the Ancient Puebloan tradition and the cultures of Casas Grandes, West Mexico, and Mesoamerica. The analysis of these three vessels and their associated tradition provides additional insight into this on-going scholarly discussion.

Deines, Dory. "Finding Terroir in Southwest Iowa." Thesis, University of North Texas, 2013. https://digital.library.unt.edu/ark:/67531/metadc283815/.
Full textAbstract:
Terroir combines the physical landscape of the vineyard with the grapevines and the methods and techniques used to produce wine from the grapes. This study used a GIS to identify the characteristics of the physical landscape in Pottawattamie, Mills, Montgomery, Fremont, and Page counties in southwestern Iowa. The components were combined in the GIS using a weighted linear index to identify areas suitable for vineyard development and to identify the general characteristics of the area. Vineyard owners were interviewed to help determine the weighting system to use in the GIS and to determine their perceptions of how the physical landscape impacts their vineyards, as well as to determine what grape varieties they plant in their vineyards and their decisions on making wine from these grapes. This information was collected to identify whether the vineyard owners had developed a sense of place for their vineyards and how this sense might aid them in the development of a terroir for their wines. The resulting perceptions about the individual wineries were then considered in conjunction with the results from the GIS modeling to understand how the physical landscape influences the concepts of sense of place and terroir in southwest Iowa. The physical landscape of southwest Iowa was fairly uniform, as were the grape varietals planted in the vineyards. This created a measure of similarity among the wineries, while individuality between wineries was then created by the wine-makers as they used different techniques to produce wine from the grapes. This allows each winery to develop a sense of place, yet be part of a larger sense of place that encompasses multiple wineries within the area.

Full textAbstract:
[Truncated abstract] This thesis investigates the phenomenon of organisational guanxi in business in the SOE hotel environment in south-west China. A general aim is to give the reader a sense of how organisational guanxi operates in this environment. It identifies the characteristics and roots of organizational guanxi and discusses the significance of its operation in this environment. This thesis also analyses the implications of the continued practice of organizational guanxi and the prospects of its future as the Chinese economy continues to evolve toward a more market orientation. In Chapter One, the phenomena of guanxi, mainzi and renqing are defined and the importance of their role in conducting business in mainland China proposed. … The findings of this new research in south-west China provide conclusive evidence that in this region the guanxi network remains the lifeblood of the business community (Kao, 1993). In addition, this research throws up some conclusions that are not aligned with that of Guthrie?s (2002) Shanghai-based findings. In Chapter Nine, The Conclusion, the major findings of this thesis are revisited and include the acknowledgement and definition of organisational guanxi, the exploration of the roots of organisational guanxi inside the danwei, the differentiation of intra-organisational guanxi from inter-organisational guanxi, the definition of the concept of guanxi neglect, and a comparison of the decay in the strength and usage of guanxi in south-west China with that in the Shanghai region.

Full textAbstract:
Drought indices based on monthly precipitation and sometimes temperature are widely used due to their simple calculation with readily available climate data. The portrayal of drought through simple precipitation anomalies or water balances when accounting for temperature may not capture the potentially complex evolution of drought events due to the timing, intensity, and frequency of precipitation events at the daily scale. In this study, we present a new drought index that incorporates a deterministic soil model, HYDRUS-1D, and daily climate data to assess how representative simple drought indices are of soil moisture status in the Southwest. Specifically, we compare our drought index with two widely used drought indices: the Standardized Precipitation Index (SPI) and the Standardized Perception-Evapotranspiration Index (SPEI). Modeled soil moisture output was summed into monthly values for direct comparison between indices. SPI and SPEI proved to be representative of soil moisture status at shallow depths, correlating best at a two-month window. SPI correlated higher with our modeled drought index than SPEI in shallow settings across all study sites. Intense drought events were controlled by the magnitude and frequency of precipitation, with large events creating water surplus and then a slow decay in soil moisture until the next large event. Furthermore, heat map correlations indicate that monitoring drought at depth is dependent upon the previous years monsoon, with the best correlating window growing with distance from monsoon onset. Modeled soil moisture showed volumetric water content increased during monsoon season and remained high through the fall and into the winter months. Higher moisture content increased hydraulic conductivity, priming the soil profile for winter recharge. We believe that the addition of a soil physics based drought index greatly improves drought monitoring conditions for the southwest.

Full textAbstract:
This analysis of faunal remains from Goodman Point Pueblo (5MT604), a large village occupied just before the ancestral Puebloans permanently left southwestern Colorado at the end of the thirteenth century, explores the effect of dietary stress during abandonment in the Four Corners region. As archaeologists, we interpret what these former cultures were like and what resources they used through what they left behind. By specifically looking at faunal remains, or remains from food resources, environmental change and dietary stress can be assessed. Identifications of taxa identified at Goodman Point are made explicit via a systematic paleontology. This is followed by site-level taxonomic abundances and spatial analysis. Then, effects of technological innovations, environmental change, and sample quality are examined as alternate explanations of shifts in foraging efficiency, particularly related to animal hunting. Analyzing why and if the availability of faunal resources changes over time helps to clarify why the ancestral Puebloans left southwestern Colorado.

Thomas, Christopher James. "Southwest Texas Junior College: Organizational transformation along the border." Thesis, University of North Texas, 2005. https://digital.library.unt.edu/ark:/67531/metadc4925/.
Full textAbstract:
This study sought to identify components of the institutional transformation of Southwest Texas Junior College from its participation in the Rural Community College Initiative (RCCI) The RCCI was centered on increasing access to educational opportunities and regional economic development in four historically poor regions of the United States. It was felt that this two-pronged approach to increase access and economic development would ameliorate poverty and provide opportunity. The pilot colleges were chosen from Appalachia, Delta South, Northern Plains (Tribal colleges), and the Southwest. Southwest Texas Junior College in the southwest border region of Texas and Mexico was chosen in 1994 as one of nine pilot college participants in the Ford Foundation project. Documentation of the college's characteristics were conducted during the 1994 and 1995 preliminary visits by Stephen G. Katsinas at the request of the Ford Foundation to find suitable rural community colleges in historically distressed areas of the United States to be invited to participate in RCCI. Follow-up site visits were conducted by Christopher Thomas in 2002, 2004, and 2005. Data was collected during all site visits by open-ended questionnaires, interviews, content analysis of documents, and observation. Extended site visits and living in the college's residence halls increased the researcher's knowledge of the region, the college, its faculty, staff, and students. Results from the study indicated Southwest Texas Junior College has undergone substantial institutional transformation as a result of its participation in RCCI. The College increased access in all eleven counties to students in its state-assigned service delivery area through increased relationships with twenty-two area highs schools, the extensive expansion of curriculum and permanent facilities at its branch campuses in Eagle Pass, Del Rio, and Crystal City, increases in its adult basic education programs, increases in its technical training programs, and by increasing its workforce training programs. The college has also increased its regional economic development by assuming a leadership role in the region for economic development activities and by increasing its use of federal, state, and local grant opportunities. The Middle Rio Grande's recognition by the federal government as a Rural Enterprise Zone (the Futuro Proposal) and its participation in the Lumina Grant Project are further demonstrations of its success at increasing regional economic development. Addition documentation and research on this institution and this region are warranted and suggested as this area's population projections continue to show sharp increases.

Full textAbstract:
[Truncated abstract] The southwest of Western Australia is an intraplate area classified as a stable continental region. It comprises predominantly Archaean and Proterozoic geology and has generally subdued topography. The region currently experiences significant seismicity in the Southwest Seismic Zone (SWSZ), which is one of the most seismically active areas in Australia and is thought to represent the highest seismic hazard of the region. In recent years, numerous scarps, potentially related to large palaeoearthquakes have been recognised not only within the SWSZ, but also in a broader region of the southwest of Australia. Palaeoseismological investigations of two of these scarps, the Dumbleyung and the Lort River scarps, confirm their association with surface-rupturing palaeoearthquakes and indicate events with likely maximum magnitudes of ~Mw 7.0 on faults of low to medium slip rates. Two trenches across the Dumbleyung Fault scarp revealed a thrust fault in alluvial sediments with two associated earthquakes in the last ca 24-60 ka. A possible Holocene age was recognised for the last recorded earthquake event exposed in these trenches. Two trenches across the Lort River Scarp show that this feature results from thrust faulting in the weathered gneissic country rock. These trenches exposed evidence of two events in the last ca 35 ka, with a likely late Pleistocene age for the last earthquake. On both sites, the earthquakes are interpreted as associated with the last phase of fault activity, which was likely been preceded by a long period of quiescence. Assessment of the earthquake hazard associated with large earthquakes at the Dumbleyung and Lort River Faults resulted in calculated peak ground accelerations of up to 2 g in the near-fault fields. Such earthquakes would significantly affect nearby towns such as Dumbleyung, Wagin, Katanning, and Esperance, but they are unlikely to cause any significant damage in Perth. The palaeoseismological investigations show that the earthquake activity in the southwest of Western Australia is not only confined to the SWSZ, as it has been considered in previous assessments of the seismic hazard, but that there is also potential for strong earthquakes across much of the region. The seismicity in the southwest of Western Australia appears to be transient and migratory. This is suggested by the lack of local relief associated with places of current seismicity and fault scarps, the widespread distribution of the fault scarps across the region, the increase in seismicity in the SWSZ following strong recent events, and the apparent long periods of earthquake recurrence at fault sites. Accordingly, the current seismicity in the SWSZ is inferred to be transient and probably associated with stress changes produced by the recent earthquakes. '...' This uplift could be associated with dynamic topography effects resulting from processes along the plate margins. The uplift is probably enhanced by a flexural response of the lithosphere to local differential loads and density contrast along the southern margin, a mechanism that may also help explain the occurrence of some earthquake activity. The results from this study, complemented by additional palaeoseismological studies must be included in future probabilistic assessments of the seismic hazard of the southwest of Western Australia.

Full textAbstract:
This study assumes that political terrorism results from conscious decision-making by groups opposing a governing system, policy or process. The kinds of terrorist activity employed depend upon such factors as the philosophy, goals, objectives, and needs of the terrorist group. This presents a comparative analysis of three types of terrorists in southwest Asia: Palestinians, Marxist-Leninists, and Muslims. The first section summarizes and compares the three groups' motivational causes, philosophies, histories and sources of inspiration. The second section compares their behavior from four perspectives: trends and patterns, level of violence, tactical preferences, and lethality. The third section identifies and categorizes socioeconomic, political and military variables associated with tactic selection and acts of terrorism.

Full textAbstract:
The Cenozoic Ailaoshan Red River shear zone marks the present day western margin of the South China Block. Along this margin are well preserved late Paleoproterozoic to early Neoproterozoic sedimentary and volcanic successions. This work examines the ages and tectonic environments for the formation of the successions, as well as significance of the regional tectono-magmatic events on the formation of widespread iron oxide-copper deposits. The oldest succession is the Paleoproterozoic Dahongshan Group. A new SHRIMP UPb age of 1675 ± 8 Ma for a tuffaceous schist unit confirms its Paleoproterozoic age. Detrital zircon ages of the Dahongshan Group range between Archean to Paleoproterozoic (ca. 2780 1860 Ma). They include a population of ca. 2400 2100 Ma grains, which have no known source region on the exposed Yangtze Block. Previous geochemical studies of metavolcanic rocks from the Dahongshan Group have suggested that these rocks were erupted in an oceanic setting. However, this study shows that the metavolcanics are extremely altered and cannot be used for reliable tectonic discrimination. Based on the characteristics of sedimentary rocks in the Dahongshan Group, it is suggested that these rocks were deposited in a continental setting. Overlying the Dahongshan Group is a thick sedimentary sequence which has been variably termed the Kunyang, Dongchuan, Huili or Xide Groups. In the past, these rocks have been considered as a Mesoproterozoic rift succession. However, no precise age constraints were available for the succession. In this study, this sequence is found to contain at least two separate tectonostratigraphic units. The oldest (ca.1140 Ma) is comprised of alkaline basalt with a geochemical and isotopic character similar to that of modern intracontinental rift basalts. The presence of Cathaysia-derived sediments in this unit indicates sedimentary transportation from the southerly Cathaysia Block to the northerly Yangtze Block (in present coordinates) in South China at that time, which suggests an impactogen scenario. The thick sedimentary sequence of what has traditionally been defined as the Kunyang Group has been found to have significantly younger depositional age of ca.1000 960 Ma. The composition of sedimentary rocks and the provenance of detrital zircons from the Kunyang Group are consistent with a foreland basin setting. The depositional age of this sequence coincides with the timing of Sibao Orogeny as determined elsewhere in the South China Block. Summary Page ii Numerous iron oxide - copper (gold) deposits occur within the rocks of the Dahongshan and Kunyang Groups. Previous studies have classified these deposits into two deposit styles: the Dahongshan-type Paleoproterozoic VMS mineralisation hosted within the Dahongshan Group, and the Dongchuan-type diagenetic carbonate and shale-hosted deposits hosted within the Kunyang Group. However, both deposit types share similarities with the iron oxide copper (gold) deposit class, such as stratabound disseminated and massive copper ores, abundance of iron oxide occurring mostly as low Ti - magnetite and haematite, and variable enrichments in Au, Ag, Co, F, Mo, P and REE. 40Ar/39Ar data from both deposit types indicate mineralisation ages of ca. 850 830 Ma and 780 740 Ma.

Full textAbstract:
Phytophthora cinnamomi Rands is a common and devastating pathogen of cultivated proteas worldwide. Webb (1997) described a Sudden Death plant disease of proteas in Western Australia (WA) protea plantations. Proteas that suffer the syndrome display symptoms such as stunted growth, wilting, chlorosis and often death. In the current study, a number of protea plantations in the southwest of WA were visited to quantify the extent that P. cinnamomi was attributing to deaths of cultivated proteas. The survey indicated that P. cinnamomi is the major cause of Sudden Death in proteas. A range of other fungi (Fusarium, Botryosphaeria, Pestalotiopsis, Alternaria) and pests (nematodes, mealy bug, scale insects) were also identified to be contributing to protea death and decline in WA plantations. In many cases the factors contributing to protea disease appeared complex, with a range of physical factors or nutritional imbalances commonly associated with these pathogens and pests. As P. cinnamomi was the major cause of death of cultivated proteas the remainder of the experiments described in this dissertation investigated its control in horticultural plantings.
Biofumigation has the potential to become an important technique in an overall integrated management approach to P. cinnamomi. In this thesis, biofumigation refers to the suppression of pathogens and pests by the incorporation of Brassica plants into the soil. Two biofumigants (Brassica juncea (L.) Czern., B. napus L.) were screened for their effect on the in vitro growth of five common Phytophthora species (P. cinnamomi, P. cactorum (Lebert & Colin) Schroeter., P. citricola Sawada, P. cryptogea Pethyb. & Laff. and P. megasperma Drechsler). Growth was determined by the measuring dry weight and radial growth of vegetative hyphae. B. juncea was found to be superior in its suppressive effect compared to B. napus. There was also significant variation in the sensitivity of the Phytophthora species to the suppressive effects of the biofumigants. P. cinnamomi was the most sensitive of the five species investigated. Where the rates of the biofumigant were sufficient to suppress growth of Phytophthora, the suppressive effect was mostly fungicidal.
To determine how B. juncea and B. napus affect the infective ability and survival of P. cinnamomi, their effects on sporangia and chlamydospores production in soil was investigated in vitro. P. cinnamomi colonised Miracloth discs were added to soil amended with the two Brassica species, before being removed every two days over an eight day period for the determination of sporangia production, chlamydospore production and infective ability. Only the soils amended with B. juncea significantly reduced sporangia production in P. cinnamomi. Both Brassica species increased the percentage of aborted or immature sporangia and reduced the infective ability of the pathogen. Neither Brassica species had any effect on zoospore release or chlamydospore production in P. cinnamomi.
Soil cores and soil leachate were collected from biofumigant-amended field soils to determine the inoculum potential and infective ability of the pathogen under glasshouse conditions. Amending the soil with both Brassica species had an immediate suppressive effect on the inoculum potential and infective ability of the P. cinnamomi. However, after this initial suppression there was a gradual increase in the recovery of the pathogen over the monitoring period of four weeks. To determine if the suppression would result in decreased disease incidence in a susceptible host, Lupinus angustifolius L. seeds were planted in the biofumigant amended soil. B. juncea amended soils reduced the disease incidence of P. cinnamomi by 25%. B. napus had no effect on disease incidence in L. angustifolius.
Although the current study had demonstrated that biofumigants could suppress the growth, sporulation and infection of P. cinnamomi, it was unclear if this would equate to a reduction in disease incidence when applied in the field. A field trial was conducted on a protea plantation in the southwest of Western Australia that compared biofumigation with B. juncea to chemical fumigation (metham sodium) and soil solarisation. The three soil treatments were used in an integrated management approach to control P. cinnamomi that included the use of a hardwood compost, mulch and water sterilisation. All treatments were monitored during their application to ensure the treatments were conducted successfully. The three soil treatments significantly reduced the recovery of the pathogen and the infective ability of the pathogen to a soil depth of 20 cm. Metham sodium was the most suppressive soil treatment and soil solarisation was the least suppressive treatment. Only the metham sodium treatment resulted in a significant reduction in the incidence of root rot in Leucadendron salignum P.J. Bergius x laureolum (Lam.) Fourc (c.v. Safari Sunset) over the monitoring period of three years.
Another field trial was conducted on the same protea plantation to compare the effectiveness of B. juncea and B. napus, without the use of other control strategies, to reduce the incidence of P. cinnamomi infection of Leucadendron Safari Sunset. The concentration of isothiocyanates was monitored for seven days after the incorporation of the biofumigants. Although both Brassica species reduced the recovery and infective ability of the pathogen, neither biofumigant reduced the incidence of root rot in Leucadendron Safari Sunset.
In conclusion, P. cinnamomi is the most common and devastating pathogen in WA protea plantations. The current study demonstrated that P. cinnamomi is sensitive to the suppressive nature of biofumigants. Biofumigants can suppress the in vitro growth, sporulation, infective ability of P. cinnamomi and reduce the incidence of the disease caused by the pathogen in the glasshouse. Of the two Brassica species investigated, B. juncea was superior in its ability to control P. cinnamomi compared to B. napus. When applied in the field, biofumigation using B. juncea was found to be more suppressive that soil solarisation, but not as effective as metham sodium.

Full textAbstract:
This quantitative study analyzed data from ModernThink’s Best Places to Work survey to describe if employees of different ethnic groups in a community college district held similar or different perspectives on aspects of the work place. ModernThink’s survey describes the perspectives of employees from the view of the individual, the workgroup, and the organization on the competencies of organizational: leadership, communication, respect, and alignment. The study analyzed responses from 457 faculty and administrators to describe workplace perspectives across the district, at seven campuses, and by ethnic group. The results revealed that the employee workgroup was neutral in its perceptions of both the perspectives and competencies for the district; by ModernThink’s criteria the district was not a best place or a poor place to work. Based on the overall responses, four campuses rated as a best place to work; three campuses were rated as neutral. Of the perspectives, one campus rated best in all three factors and two campuses rated best on two of three factors. Rating variations between the two ethnic groups were minimal across the district and only diverged at two of the seven campuses. Although the study did not examine campus culture or climate, the findings suggest that campus climates vary and likely influenced the survey responses.

This thesis discusses the intermediate waters of the Pacific over space and time. Initially, by using geochemical tracers to look at the present distribution, sources and mixing of the water masses. Secondly, by using oxygen and carbon isotopes from sediment cores to study changes in Antarctic Intermediate Waters (AAIW) over the late Quaternary in the north Tasman Sea. The sediment cores also provide sedimentological data on the hemipelagic sedimentation in the Capricorn Channel in the southern Great Barrier Reef as well information on changes in the East Australian surface current (EAC) over the last glacial-interglacial transition.

Full textAbstract:
The problem addressed in this study is how selected universities in the South and Southwest recognize and attempt to deal with alcohol use and other drug use among students. The purpose of the study was to determine current practices and policies concerning student alcohol and drug use among the 20 selected universities. The data were obtained by means of a descriptive survey questionnaire which was mailed to 20 selected universities under the jurisdiction of the Southern Regional Accrediting Board. The instrument was designed to identify practices and programs concerning student alcohol and drug use. A copy of each institution's alcohol and drug policy was requested. The content and procedures of the programs implemented by the responding institutions were reviewed, in order to evaluate the extent and degree to which they provide for the recognition, education, intervention, and treatment for students with alcohol- or drug-use problems. Results are presented in tabular form. Of the 20 major state-supported universities which were mailed questionnaires, 75% returned usable instruments. All responding institutions felt they have an alcohol or drug problem of some magnitude, and all either have, or believe they have, some kind of policy to deal with substance use by students. All of the responding institutions also indicate that they have various programs in operation which deal with student substance use and abuse. Since this was a regional study the results are not necessarily generalizable. On the basis of the literature reviewed and the survey responses received, an authentic problem with student alcohol and drug use exists on campus. The institutions surveyed appear to recognize a problem; however, the results of this study reveal that most have yet to develop an effective or coordinated strategy to combat student alcohol and drug abuse.

Full textAbstract:
Salsola australis is an introduced weed of crop and pasture systems in the Western Australian broad acre cropping and pasture region (wheat-belt). This thesis investigated the classification, biology and ecology of the genus Salsola in southwest Australia, as well as modelling the effectiveness of possible weed control practices. Prior to this research, S. tragus was the only recognised species of the Salsola genus within Australia. However, genetic analysis revealed that four genetically distinct putative taxa of the genus Salsola were found in southwest Australia, none of which were S. tragus. The taxa that is the most prevalent agricultural weed was classified as S. australis, but the other three putative taxa could not be matched to recognised species. All four taxa were diploid (2n = 18), as opposed to tetraploid (2n = 36) S. tragus. Within the agricultural system of southwest Australia, S. australis plants established throughout the year, although the majority of seed production occurred in late summer and autumn. Total seed production (138-7734 seeds per plant) and seed viability (7.6-62.8%) of S. australis were lower than that reported for other agricultural weed species of the Salsola genus. Seed dispersal occurred when the senesced plants broke free of their root system to become mobile. Wind driven plants travelled and shed seed over distances of 1.6 to 1247.2 m. Movement of approximately half the plants was restricted to less than 100 m by entanglement with other S. australis plants within the stand. Some seed was retained on the senesced plants, but the germinability of this seed fell to less than 2% in the two month period following plant senescence (i.e. a decline of 79%). Once seed shed into the soil seed bank, anywhere from 32.3 to 80.7% of the viable seeds germinated in the year following seed production, with the rest remaining dormant or degrading. A model of the life cycle of S. australis based on the population ecology data indicated that the dormant seed bank had very little effect on annual seedling recruitment, but seed dispersal from neighbouring populations had a large impact on population growth rate. Therefore, the most successful weed control measures were those that restricted seed dispersal from neighbouring populations, or those that were applied to all populations in the region rather than to a single population. Weed control techniques applied to a single population, without reducing seed dispersal, could not reduce population size.

The purpose of this study was to examine the use of computer and communications technologies at four-year public/private college and university career centers that are members of the Southwest Association of Colleges and Employers (SWACE).
The findings of this study reveal that (a) all career centers are now using computer and telecommunications technologies for at least one office function; (b) small institutions do not use technologies as much as large institutions because they have fewer financial resources, less technical
support from institutions, fewer personnel, and they also need time to learn to use technologies effectively; (c) public career centers are more willing to explore new technologies but private career centers mostly adopt and implement proven technologies; (d) career education does not utilize
technologies as much as career counseling or job placement functions; (e) lack of financial resources and lack of technical support are major barriers to a technological infusion; and (f) technologies, including electronic student databases, computerized presentations with the network connection, and
OCR scanners, will be needed in the near future.

Full textAbstract:
This thesis locates the global heroin trade within a world-systems theoretical framework. While the thesis identifies some of the factors responsible for the success of the international heroin trade, the primary aim is to focus on one facilitating aspect global financial flows of illegal or hot money. Central to the argument is that international production and trade in illegal heroin are buttressed by cycles of economic contractions within the world economy and by a global financial system that provides the means for the heroin trades profits to be easily laundered and invested in the legal economy. To illustrate the utility of these approaches in terms of a world-systems context, the thesis employs a global commodity chain perspective and elaborates the case study of Hüseyin Baybasin, a highly prominent convicted Kurdish businessman who has sometimes been identified as the worlds leading international heroin trafficker. This particular case study permits us to examine not only the complex web of historical, cultural, social, economic and political interactions within the international heroin trade, but also how the global heroin commodity chain is relevant to the broader debate about secessionist ethnic nationalism and development in the Third World. Focusing on Turkey, the thesis outlines the early historical periods in which different traditional patterns have prevailed for the majority of Kurdish people, and explains the disappearance of these patterns through the process of modernisation and globalisation, and how this relates to the global heroin trade. The argument thus provides an alternative, world-systems perspective to the more familiar accounts of international heroin trafficking that tend to focus on conventional interpretations of supply and demand and the activities of law enforcement agencies in physical interdiction.

Full textAbstract:
The number of public markets in the United States increased from more than 300 in the 1970s to more than 8,600 by 2016. This increase in markets is related to changes in food production, localism and the local food systems movement, socioeconomic changes, cultural changes, and perceptions of embeddedness. Research on the underlying conditions for the success of public markets is scant in the United States, and especially in the USDA Southwest Region. This study provides analysis of public market locations as compared with non-market locations by drive-time trade areas during a 20-year period, 1996 and 2016, to gain further insights into factors leading to their success. The results from logit regression analyses and simulations of socioeconomic, college-town status, and climate-grid classifications find an increased likelihood of public markets with population, education, college town status, and some climate-grid locations. Median income, surprisingly, has an inverse relationship with public market success. Qualitative data and a literature review point to three types of embeddedness that motivate customers to attend public markets. This study concludes that "local nontradable consumer goods" tied to place are offered at these "nontradable consumption amenities." These amenities are "third places" that promote social interaction and become important places of community, farmer support, and commerce across the Southwest Region.

Full textAbstract:
Tropical forests of the world are fast disappearing and there is a race to understand patterns of species distribution in space and time. Studying species distributions can provide better frameworks for conservation of these ecologically important patches of floral and faunal diversity. The island of Sri Lanka is a well known harbour of unique and highly threatened biodiversity. Tropical lowland forest is remnant in the south-west of the island now mainly existing in small patches. While most are small disturbed fragments, Sinharaja Forest Reserve represents one of the largest remaining patches of this important ecosystem. As a UNESCO World Heritage Site and a Man and Biosphere Reserve, it has a dual role as a conservation area and a historically important resource forest. While the distribution of vegetation diversity has been well documented, analyses of invertebrate species distributions are lacking. This thesis investigated a key arthropod group, ground dwelling ants, in relation to environmental gradients within the forest. Cumulative results demonstrate the high diversity of the forest patch. In an area representing less than half the reserve, over 173 ground dwelling ant species were found in distinct assemblages throughout the forest. Since the forest is located upon a series of parallel ridges, ant species distribution was first analysed in terms of this small elevation change. Species richness declined over a vertical incline from 430 m to 660 m, highlighting a possible small-scale, mountain mass effect. This section of the reserve is also characterised by a patch of once-logged forest (30 years previously). A study was undertaken to investigate whether there were residual effects of selective logging on the reserve.Significant differences between species assemblages in once-logged forest and unlogged forest add to growing evidence that selectively logged forests continue to remain distinct from unlogged forest even after decades of regeneration. Ant distribution was then analysed for their relationship with habitat heterogeneity and tree species distribution. Long-term research on tree species in the SFR has demonstrated a close relationship to habitat complexity. Ant species appear to respond more to the structural heterogeneity of the vegetation than to actual topographic variation within the forest. From a conservation perspective, maintaining the integrity of this highly diverse forest is imperative. The impact of anthropogenic land uses surrounding the forest was investigated in terms of ant assemblages along the forest edges. Significant differences were found between assemblages within the edges bordered by different matrix types. Even relatively large forest remnants can be affected by the surrounding matrix land uses and encouraging the growth of structurally similar vegetation and maintaining low disturbance along the borders should attenuate the effect of the edge. Overall, the highly heterogeneous distribution of ant assemblages within the SFR demonstrates the potential for other small patches to be harbours of further species diversity. Future research should be undertaken to assess the diversity and distribution of ant species within this region and encourage the protection of this remnant diversity.

Full textAbstract:
The impact of a canker disease of Corymbia calophylla (marri) in the southwest of Western Australia (WA) has increased substantially since it was first observed causing decline and death of this species in the 1970s. By the early 1990s there were expressions of concern and calls to determine the cause and management options. Despite this, there has been very little research into the incidence, severity and possible causes of the disease. There are,
however, historical reports dating back to the 1920s of a canker disease of amenity planted C. ficifolia caused by Sporotrichum destructor, though the diagnosis and Latin description were never published. It has been suggested that there may be links between this species and the genus Quambalaria, a group containing leaf and shoot pathogens of species of Eucalyptus and Corymbia.
This study examined the incidence and symptomology of the disease, the range of fungal species associated with healthy and diseased C. calophylla, and the pathogenicity of
isolates obtained from these surveys. Also investigated was the identity of the pathogen, S. destructor, historically attributed to canker disease of C. ficifolia, to determine whether this pathogen is responsible for the current epidemic of C. calophylla canker and if it is synonymous with Quambalaria.
Cankers were present on trees across the range of surveyed sites, with lesions occurring on trunks, branches or twigs of 25.7 % of the C. calophylla surveyed. Canker incidence was significantly greater on trees present at remnant sites, such as roadsides and in paddocks, than forest trees being 38 % and 13.3 %, respectively. Tree height, trunk diameter at breast height and crown position, size and health ratings were significant predictors of canker
presence, with cankers more common on larger, older trees and trees with poor crown condition. Bark cracks exuding kino were present on 48 % of the surveyed trees, and when
dissected, lesions were observed on 40 %, suggesting that these cracks could be the initial stages of canker disease. This was confirmed by the observation of a number of cracks that developed into perennial cankers during the three year study. Monitoring of canker development and the examination of transverse sections showed the circumvention of host
defenses by the pathogen and the subsequential walling off response of the host (which typifies perennial cankers) was not necessarily an annual event, with no change observed in
some cankers over the three year period, while others progressed rapidly in that time, occasionally to the point of girdling and killing the host.
Initial surveys isolated 44 fungal species from healthy and diseased C. calophylla, with opportunistic pathogens including Endothiella eucalypti and Cytospora eucalypticola
common. Subsequent surveys foccussed more on a potential pathogen in the genus Quambalaria, which was rarely isolated from active lesions, presumably because of its
slow growth rate, but which sporulated consistently on the surface of older sections of the cankers.
DNA sequences confirmed that Q. cyanescens and Q. pitereka are present in southwest WA, with the latter associated with leaf and shoot disease. A third and new species of
Quambalaria was isolated from cankers. Comparisons of disease symptoms and conidiogenesis indicate this species is synonymous with S. destructor. The species is
formally described here as Q. coyrecup T. Paap sp. nov.
A pathogenicity trial was unsuccessful in causing disease symptoms in trees inoculated with core plugs taken from canker lesion margins of diseased trees, though the time frame and environmental factors may not have been adequate for disease development. The core plug inoculation method may also have failed because opportunistic pathogens which were frequently isolated from lesions out-competed Q. coyrecup (paralleling the results achieved by culturing from lesions). Quambalaria coyrecup caused symptoms matching those observed in natural infections when suitable hosts were inoculated, confirming it is the fungus responsible for the current canker disease of C. calophylla and C. ficifolia. Endothiella eucalypti also caused
significant lesions, though these were not typical of natural infections, which together with its frequent isolation from both healthy and diseased trees suggests it is an opportunistic pathogen, potentially contributing to disease development in trees already infected with Q.
coyrecup.
Isolates of Q. pitereka from WA and eastern Australia both caused typical shoot blight symptoms in the WA hosts C. calophylla and C. ficifolia, and the eastern Australian host
C. maculata, though a larger path trial is required to examine the possibility of host specificity. Quambalaria cyanescens was non-pathogenic in all inoculation trials.
The current cause of cankers in C. calophylla is now known to be the same as the fungus historically implicated in the canker disease of C. ficifolia, when at the time it was
described as an endophyte doing little or no damage in C. calophylla. Thus, it is of immediate importance to determine the factors driving this decline, and develop control and management options.

Full textAbstract:
The problem of this study concerns the values, beliefs, and characteristics of Hispanic students attending a large urban southwestern university. The study is qualitative and utilizes the constant comparative research method. Data is gathered from interviews with 21 Hispanic students, campus surveys, university records, a census report, and observation of campus activities. The literature review spans organizational culture, campus culture and subcultures, as well as studies regarding Hispanic students. The findings introduce the students and report their perspectives in both their own words and in summarized themes for each research question. In summary, Hispanic students and their college experiences are diverse. They major in a wide range of disciplines, come from varying socio-economic households, have parents with varying levels of education, are surprised by various aspects of college, and they do not all speak Spanish.

Full textAbstract:
Buruli ulcer (BU) is an environmental bacterium caused by Mycobacterium ulcerans. Modes of transmission and hosts of the disease remain unknown. The purposes of this study are to explore the environmental factors that are possibly explain the spatial distribution of BU, to predict BU cases by using the environmental factors, and to investigate the impact of land use and land cover change on the BU distribution. The study area covers the southwest portion of Ghana, 74 districts in 6 regions. The results show that the highest endemic areas occur in the center and expand to the southern portion of the study area. Statistically, the incidence rates of BU are positively correlated to the percentage of forest cover and inversely correlated to the percentages of grassland, soil, and urban areas in the study area. That is, forest is the most important environmental risk factor in this study. Model from zero-inflated Poisson regression is used in this paper to explain the impact of each land use and land cover type on the spatial distribution of BU. The results confirm that the changes of land use and land cover affect the spatial distribution of BU in the study area.

Applied Science, 1996. http://erl.canberra.edu.au./public/adt-AUC20060822.132115.
Full textAbstract:
This study examines and demonstrates the value of a matrix approach in the
discipline of conservation and the concerns specific to the conservation of
archaeological and ethnographic objects. The chapters identify the relevance of
the matrix to current conservation practices through a history of artifact
conservation and a discussion of the factors that compromise the conservators'
role in the study and preservation of material culture. The discussion evaluates
the nature of systematic research collections, the impact of legal issues, and the
ethics of including cultural context as important aspects in the development of
the matrix approach.
The matrix approach provides the conservator with a number of variables or
categories of information that may assist in the determination of an appropriate
conservation process. In this study, the matrix approach was tested on a
number of artifact objects. To provide a common link, all of the objects were
characterized by paint on some form of cellulose (wood or a wood-like
substrate). The object cases were from both ethnographic and archaeological
contexts, and the work involved both laboratory procedures and consideration
of non-laboratory (i.e. legal, cultural, ethical) aspects. The specific objects
included (1) a probable tiponi of archaeological (Anasazi culture) context, (2) a
group of coiled baskets of archaeological (Mogollon culture) context, (3) a
kachina doll of ethnographic (Hopi culture) context, (4) a group of prayer
sticks of archaeological (Puebloan and Tohono O'Odham) context, and (5) a
fiddle of ethnographic (Apache culture) context.
By recognizing the unique and diverse aspects of anthropology collections, the
conservator who uses a matrix approach is better equipped to work with
archaeologists on sites, with curators and exhibit designers in museums, and
with claimants (or the descendants of an object's maker) in carrying out the
multiple activities frequently involved in the conservation of objects as they
exist in an ever broadening and more political context.

Full textAbstract:
[Truncated abstract] A number of controlled and natural seismic sources are utilised to model the Pwave velocity structure of the southwest of the Yilgarn Craton, Western Australia. The Yilgarn Craton is one of the largest pieces of Archaean crust in the world and is known for its gold and nickel deposits in the east and intraplate seismicity in the west. The aim of the project is to link 2D and 3D models of variations in seismic velocity with the local seismicity and geology. A new set of seismic refraction data, acquired in 25 overlapping deployments between 2002 and 2005, has been processed, picked and analysed using forward modelling. The data comprise two perpendicular traverses of three-component recordings of various delay-fired blasts from local commercial quarries. The data were processed using a variety of techniques. Tests were carried out on a number of data enhancement and picking procedures in order to determine the best method for enhancement of delay-fired data. A new method for automatic phase recognition is presented, where the maximum of the derivative of the rectilinearity of a trace is taken as the first break. Complete shot gathers with first break picks for each seismic source are compiled from the overlapping deployments. ... The starting 3D model was based on the models produced by 2D forward modelling. 14 iterations were carried out and the best-fit 3D model was achieved at the 10th iteration. It is 35% better then the current model used to locate earthquakes in this region. The resultant velocity block model was used to iii construct a density block model. A relative gravity map of the southwest of Yilgarn Craton was made. The results of 2D forward modelling, 3D tomography and forward gravity modelling have been compared and it was found that the HVZ is present in all models. Such a zone has been previously seen on a single seismic refraction profile, but it is the first time, this zone has been mapped in 3D. The gravity high produced by the zone coincides with the gravity high observed in reality. There is strong evidence that suggests that the HVZ forms part of the Archaean terrane boundary within the Yilgarn Craton. The distribution of the local seismicity was then discussed in the framework of the new 3D velocity model. A hypothesis, that the primary control on the seismicity in the study area is rotation of the major horizontal stress orientation, is presented. It is also argued that the secondary control on seismicity in the SWSZ is accommodation of movements along major faults.

Full textAbstract:
The purpose of this study was to investigate and predict Latino male student retention using ACT’s Engage College survey at a research university in the southwestern region of the U.S. ACT’s Engage survey was designed to predict first-year college retention using 10 psychosocial measures. However, no empirical study exists to support ACT’s claim especially for Latino male students. Data from a four-year research university between 2009 and 2011 were analyzed with logistic regression. Logistic regression analysis was performed for the whole sample (N = 8,061) and for the Latino male subsample (n = 860). In the entire sample’s first regression model, high school grade quartile and SAT score as well as demographic variables were used as predictor variables. In this model, the independent variables of high school grade point average quartile, SAT score, gender, and race made statistically significant contributions to the model (Nagelkerke R2 = .031, p < .01). In the entire sample’s second regression model, ACT’s 10 psychosocial variables were added to the first regression model as predictor variables. Results indicated the instrument was valid for the freshmen as a whole because five out of 10 psychosocial measures displayed statistically significant odds ratios (ORs) for predicting retention: (a) Commitment to College (OR = 1.006, p < .01), (b) Academic Discipline (OR = 1.005, p < .01), (c) Social Activity (OR = -.997, p < .01), (d) Social Connection (OR = 1.004, p < .01), and (e) Academic Self-Confidence (OR = -.997, p < .01). Regarding the subsample of 860 Latino males, none of the 10 psychosocial measures produced statistically significant results. The findings indicate the need to determine a new way of identifying at-risk Latino male students because current methods have failed to build a robust predictive model for this student population.

Full textAbstract:
This dissertation presents a thematic study of the novels of John Nichols. Intended as an introduction to his major works of fiction, this study discusses the central themes and prominent characteristics of his seven novels and considers the impact of the Southwest on his work. Chapter One presents biographical information about Nichols, focusing on his political awakening and subsequent move to Taos, New Mexico. A visit to Guatemala, after the publication of The Sterile Cuckoo. his first novel, brought Nichols to a realization that America was not a benevolent world power. He began to consider capitalism a voracious, destructive economic system, a view which informed the subjects and themes of his five novels written after The Wizard of Loneliness. In 1969, Nichols left New York City, moving to Taos, New Mexico, an area with a history of physical and economic aggression against its predominantly Native American and Hispanic population. The five polemical novels, all set in northern New Mexico, were written after this move. Chapters Two through Four discuss Nichols's seven novels, analyzing theme and reviewing critical response. /V Chapter Two discusses The Sterile Cuckoo (1965) and The Wizard of Loneliness (1966), novels written prior to Nichols's political awakening. Both of these books are rite-of-passage novels which focus on relationships. Chapter Three analyzes The New Mexico Trilogy: The Milagro Beanfield War (1974), The Magic Journey (1978), and The Nirvana Blues (1981). These three novels depict the exploitation of people, the displacement of cultures, and the despoliation of land in the name of progress. Chapter Four considers A Ghost in the Music (1979) and American Blood (1987). Although these two books differ greatly in tone and subject, they are similar in the general theme of waste--waste of human potential and human life. Chapter Five identifies the prominent characteristics and reviews the major themes of Nichols's novels. It concludes with a discussion of the impact of the Southwest on Nichols and his literature.

Full textAbstract:
The purpose of this study was to determine whether: 1) Southwest Region TRIO high school students between the years 1991 - 2001 continued to college immediately after high school at rates significantly different than similar population students on national and state levels; and 2) immediate college continuation for this group was a function of social and economic characteristics including race, gender, parental education, and home-care environment. The sample included 414 TRIO program participants from Texas, Oklahoma, New Mexico, Louisiana, and Arkansas. Data on the 414 participants were gathered using an existing database containing demographic and post-secondary enrollment information on study participants. The findings of this study reveal Southwest Region TRIO students during this ten-year period continued to college immediately after high school at rates not significantly different than the national low-income population of students. Results indicate that when compared to all students in the five-state southwest region, the majority low-income, first-generation TRIO population continued to college at rates not significantly different than all-income students in the region. Findings of this study also revealed select social and economic characteristics were not predictors of immediate college continuation for this group. Finally, the study showed out-of-home care environment students continued to college at significantly higher rates than in-home care Southwest Region TRIO students.

Full textAbstract:
Through the use of natural history records, published literature, and personal sampling (2011-2016) a total of 454 caddisfly species represented by 24 families and 93 genera were documented from the south-central United States. Two Hydroptilidae species were collected during the 2011-2016 collection efforts that are new to the region: Hydroptilia scheringi and Mayatrichia tuscaloosa. Eightteen species are endemic and 30 are considered species of concern by either federal or state agencies. The majority of each of these groups is Hydroptilidae, or microcaddisflies. Trichoptera community structure, by minimum number of species, was analysed in conjunction with large-scale geographical factors to determine which factor illustrated caddisfly community structure across the region. Physiographic provinces compared to other geographic factors analyzed best-represented caddisfly communities with a minimum of 10 or more species. Statistically, Hydrologic Unit Code 4 (HUC 4) was the most significant geographical factor but low number of samples representing this variable rendered it less representative of caddisfly community structure for the study area.

As fortificações e atalaias existentes nas Costas Vicentina e Alentejana, bem como no arco Tróia-Sines, assentam num sistema de defesa e vigilância da costa, que se distribui por três áreas principais, a Costa Sul, a Costa Ocidental e a zona do Pessegueiro até Sines, onde se inclui Vila Nova de Milfontes, sendo o espaço geográfico entre Sines e Tróia, uma região distinta das restantes, devido a características especiais.
Esta análise baseada na discrepância dos diversos arqueossítios, influenciada por múltiplos factores, antrópicos e naturais, e também pela confrontação de opiniões de vários autores, ajudam a compreender a originalidade desta parte do território nacional, relativamente à protecção de pessoas e bens.
O trabalho, alicerçado numa pesquisa bibliográfica exaustiva, sobre artilharia e arquitectura militar e numa prospecção territorial bastante extensa, foi por vezes árduo, mas extremamente gratificante, quando se traz ao conhecimento um monumento já há muito desaparecido ou até mesmo esquecido.
A disposição estratégica das fortificações e atalaias, assim como o surto empreendedor destas construções, por alguns dos governadores do Algarve, durante a ocupação filipina e posteriormente no período da Restauração, foram os objectivos primordiais desta dissertação, ao mesmo tempo que se tenta sensibilizar as academias, as instituições e as gentes, para a necessidade e obrigatoriedade de preservação dos “sítios” deste “Portugal Moderno”.
Por fim, foi elaborada uma ficha por cada monumento, reflectindo o estado de conservação, sendo também apresentadas algumas propostas de valorização do arqueossítio; Abstrat:
The fortifications and watchtowers existing Coastal Vincentian and Alentejo as well as the arch-Troy Sines, based on a system of defense and coastal surveillance, which is spread over three main areas, the South Coast, the West Coast and the area of Peach to Sines, which includes Vila Nova de Milfontes, being the geographical space between Sines and Troy, a region distinct from the others, because of special features.
This analysis based on the discrepancy of several archeological sites, influenced by multiple factors, anthropogenic and natural, and also by the confrontation of opinions of various authors, help to understand the originality of this part of the country, for the protection of persons and properties.
The work, based on a comprehensive literature search on artillery and military architecture and a territorial prospecting quite extensive, it was sometimes difficult but extremely rewarding when it brings to knowledge a monument has long since disappeared or even forgotten.
The strategic layout of the fortifications and watchtowers, as well as the outbreak entrepreneur these buildings, by some of the governors of the Algarve during the occupation Filipino and later in the period of the Restoration, were the primary objectives of this dissertation, while trying to raise awareness of the academies institutions and the people to the need and obligation to preserve the "sites" of this "Modern Portugal."
Finally, we created a record for each monument, reflecting the condition, and also presents some proposals for enhancement of archeological site.

King, Charla. "Middle Men: Establishing Non-Anglo Masculinity in Southwestern Literature." Thesis, University of North Texas, 2003. https://digital.library.unt.edu/ark:/67531/metadc4259/.
Full textAbstract:
By examining southwestern masculinity from three separate lenses of cultural experience, Mexican American, Native American and female, this thesis aims to acknowledge the blending of masculinities that is taking place in both the fictitious and factual southwest. Long gone are the days when the cowboys chased down the savage Indians or the Mexican bandits. Southwestern literature now focuses on how these different cultures and traditions can re-construct their masculinities in a way that will be beneficial to all. The southwest is a land of borders and liminal spaces between the United States and Mexico, between brown and white, legal and illegal. All of these borders converge here to create the last American frontier. These converging borders also encompass converging traditions, cultures, and genders. By blending the cowboy, the macho, and the warrior, perhaps these Southwestern writers can construct a liminal masculinity more representative of the southwest itself.

Younger, Alexandra Carla. "Lithic Production at the Mesilla Phase Placitas Arroyo Site Complex Doña Ana County, New Mexico." Thesis, University of North Texas, 2019. https://digital.library.unt.edu/ark:/67531/metadc1538785/.
Full textAbstract:
This study of lithic analysis shifts attention from typological studies to explicitly behavioral analyses, complimenting studies of both intrasite and intersite patterns of variability and change. Analysis of several assemblages from the Placitas Arroyo site complex reveals changing patterns of raw material procurement and selection, core reduction strategies, as well as tool production and discard. The most striking result thus far is the quite uniform emphasis on flake production from well-prepared cores, and the near absence of manufacture or maintenance of bifacial tools, especially projectile points. Associated with common ground stone artifacts, the flaked stone materials may well represent intensive food processing. Regardless, the technological patterns being revealed by this approach illustrate a productive new means to gain insights into changing behaviors in the Jornada Mogollon cultural tradition.
