A Longitudinal Investigation of Dropout among Native and non-Native High School Students

McCoy, Patrick James 06 1900 (has links)
*pages 337, 339, 341, 343, 345, 347, 350, 352 were removed from text. / Most research on secondary school dropout has been cross-sectional, and this has made it difficult to know whether the differences observed between dropouts and persisters are antecedents or consequences of attrition. Furthermore, little is known about the causes of dropout among non-majority students such as native Indians. Investigators also have neglected to consider the utility of using theoretical frameworks that have proved useful in understanding various behaviours. This thesis was directed at learning which variables contribute to dropout among Native and nonNative students and at delineating combinations of variables that are useful predictors of enrollment status. The relative merits of the Ajzen-Fishbein model and a general expectancy-value approach also was of concern. To these ends, a longitudinal, multivariate investigation was undertaken. Information from school records and questionnaires was used to determine which factors distinguished students who had persisted from those who had discontinued 1 year and 3.7 years after the initial survey. The results revealed that dropout can be predicted with considerable accuracy even over several years. Intentions, absenteeism, grade average, and perceived value of education were shown to be the most important predictors. Information in school records enabled good prediction. Of the two models, the Ajzen-Fishbein framework showed the most promise. Although the data were consistent with Fishbein's conceptualization of how intentions are formed, it was shown that the model needs refinement in accounting for actual behaviour. On the basis of the findings from this and other research, suggestions are given for decreasing attrition. / Thesis / Doctor of Philosophy (PhD)

Functional comparisons between formal and informal tools sampled from the Nenana and the Denali assemblages of the Dry Creek Site

Hall, Patrick T. 29 December 2015 (has links)
<p>This research involved low powered microscopic analysis of usewear patterns on the utilized edges of formal and informal tools sampled from the Nenana component (C1) and the Denali component (C2) of the Dry Creek Site. Dry Creek is one of the type sites for the Nenana Complex, which is often contrasted with the Denali Complex in Late Pleistocene archaeological studies of central Alaska (12,000&ndash;10,000 B.P.). There are twice as many unifacial scrapers than bifacial tools in the C1 formal tool assemblage. The C1 worked lithic assemblage contains a relatively high number of unifacially worked endscrapers and side scrapers when compared to the number of bifacial knife and point technology. The technological makeup of the formal tools sampled from the Denali component is characterized by the manufacture and use of a higher number of bifacial knives and projectile points. The presence of microblades within C2 and the absence of microblades in C1 are often cited as the most significant technological difference between these two tool kits. The analysis presented here suggests that with or without microblades, the Nenana and Denali components are different tool kits. However, differences in utilization signatures between formal bifacial knives and scrapers tools indicate that technological variability within C1 and C2 at Dry Creek may largely be shaped by early hunting and butchering versus later stage butchering and processing activities. </p>

Non-Native Invasive Plants of Arizona

Howery, Larry D., Northam, Ed, Meyer, Walt, Arnold, Jennifer, Carrillo, Emilio, Egen, Kristen, Hershdorfer, Mary January 2009 (has links)
84 pp. / First Edition Published, 2001 / The noxious weed problem in the western United States has been described as, a biological forest fire racing beyond control because no one wants to be fire boss. Indeed, when small weed infestations are left unchecked, they can grow exponentially and spread across the land much like a slow-moving biological wildfire. However, land consumed by fire usually recovers and is often more productive than before the fire occurred. On the other hand, land consumed by noxious weeds may be irreversibly changed and never again reach its full biological potential.

Textbooks, classroom communication and literacy development in a multilingual school in Ghana

Opoku-Amankwa, Kwasi January 2008 (has links)
This study explores language and literacy learning in a multilingual classroom in Ghana. The aims are three-fold: to identify characteristics of an English textbook that facilitate the pupils' literacy development and learning; to investigate how a policy on book use is interpreted and implemented; and to explore how an English-only language-in-education policy functions in a multilingual classroom.

The house on the hill| A 3800-year-old upland site on Adak Island, the Aleutian Islands, Alaska

Gordaoff, Roberta Michelle 24 January 2017 (has links)
<p>The 2011 excavation of Feature 9, a 3800 cal B.P. semisubterranean house at ADK-00237 on southwest Adak Island, is the only Neoglacial house excavated in the central Aleutian Islands and the only upland site excavation in the Aleutian Islands. House structural features, lithic debitage and tool analysis, sediment analysis, and spatial analysis are used to determine if upland household activities in Feature 9 differ from household activities in coastal Neoglacial houses. The complex hearth features at ADK-00237 are similar to those at the Amaknak Bridge (UNL-00050) site on Unalaska Island. The artifact assemblage at ADK-00237 is similar to other Margaret Bay phase sites in the eastern Aleutian Islands with the notable absence of fishing and hunting equipment and midden remains. Core and blade technology include one microblade core and two blade-like unifaces. Unifacial technology was more prevalent than bifacial technology and most tools were informal flake tools. The comparable tool assemblages suggest similar activities occurred in Feature 9 as at other Margaret Bay phase houses in the eastern Aleutian Islands. There is no evidence the Arctic Small Tool tradition (ASTt)-like artifacts from Chaluka (SAM-00001) and Margaret Bay (UNL-00048) were identified at ADK-00237. The measurable differences in the upland site of ADK-00237 to coastal houses are that Feature 9 and the two additional houses were not stone-lined, it has a smaller assemblage size, there is a lower frequency of points within the assemblage, and no definitive fishing or hunting equipment was found. Given the available evidence, ADK-00237 was likely a lookout location, based on its proximity to a coastal village (ADK-00025) and its views and easy access to three other water bodies, Adak Strait to the west, South Arm Bay to the north, and Bay of Waterfalls to the southeast. ADK-00237 could also have been a refuge.

Gesture-speech bimodalism in Arapaho grammar| An interactional approach

Sandoval, Rich A. 02 November 2016 (has links)
<p> Arapaho is an Algonquian language with few remaining speakers, but it is well represented in the literature (e.g. Salzmann 1961). The Arapaho dialect of Plains Indian Sign Language has also received a considerable amount of attention (e.g. West 1960). However, there is scant attention to an easily observable property of Arapaho: The manual gestures used by Arapaho speakers are cross-linguistically atypical. The configurations and precision of the gestures, as well as how they are integrated with speech, are much more conventional than what has been reported for other spoken languages. In this dissertation, I take a first step in describing the relationship between gesture and speech in Arapaho, and I use the term 'bimodalism' to underscore the linguistic nature of this relationship. </p><p> I also address the problem of how to approach a description of bimodalism. The classic approach to language description has framed researcher interests, methodologies, and documentational techniques in a way that does not motivate an analysis of the linguistic potential that gesture might have together with speech. I therefore use an interactional approach, which has a methodology and theoretical framework that is more sensitive to bimodalism (e.g. Fox 1987; Hanks 1990; Goodwin 1996; Enfield 2003; Blythe 2010). </p><p> I build on previous work on Arapaho grammar (notably Cowell and Moss Sr. 2008) by using the interactional approach to examine linguistic reference within Arapaho speakers' spontaneous narratives. I argue that hand pointing and spoken demonstratives are complementary resources that Arapaho storytellers use to signal discourse relevance, which involves the relational statuses and spatial arrangements of the characters in their narratives. I show the depth of the relationship between pointing and demonstratives in Arapaho by examining a bimodal construction that I call the &ldquo;viewpoint anchoring construction&rdquo;.</p>

A Glimpse of African Identity Through the Lens of Togolese Literature

Charles-Galley, Marie Line J. 15 April 2019 (has links)
<p> Togo, this small West African nation, is still relative unknown, even in today's jet set world. The Western world is only now discovering the numerous advances Togo has made in it social and economic policies, but most of all in its political conjectures. After its Independence on April 27, 1960, Togo had barely begun its journey to democracy when the dictatorship of Gnassingbe Eyadema became the yoke of the people for over thirty-one years, on April 14th, 1967. The consequences of the stranglehold exercised by Gnassingbe was to shut the nation's cultural growth and cause the people to close in onto themselves and build a protective barrier between themselves and the rest of the world.</p><p> Yet, Togo had great beginnings. It was one of the pioneers of Sub-Saharan literature, publishing in 1929 one of the first true African novels still read today. In 1929, native son Felix Couchoro, was among the first Sub-Saharan authors to write a novel which gave agency to an African protagonist in a story set in Africa, with an African-themed plot, and with a conclusion that aimed at rethinking African society. Couchoro was the first to look deeply into his culture and the social identity of his nation. He brought forth suggestions that would help in Togo's growth and insure its successful battle for Independence. </p><p> In doing so, however, Couchoro also created great controversy around a subject which continues to plague not only Togelese people, but all Africans who feel pulled in two directions: preserving their authentic traditional customs while taking an active part in the modern world, through economic improvements as well as technological advances. In this dissertation, I will first study Couchoro's flagship novel which was the starting point of this quest for a modern identity, then analyze how subsequent Togolese writers have taken up Couchoro's legacy.</p><p>
