The Neoglacial Landscape And Human History Of Glacier Bay, Glacier Bay National Park And Preserve, Southeast Alaska, Usa, Cathy Connor, Greg Streveler, Austin Post, Daniel Monteith, Wanye Howell Jan 2009

The Neoglacial Landscape And Human History Of Glacier Bay, Glacier Bay National Park And Preserve, Southeast Alaska, Usa, Cathy Connor, Greg Streveler, Austin Post, Daniel Monteith, Wanye Howell

United States Geological Survey: Staff Publications

The Neoglacial landscape of the Huna Tlingit homeland in Glacier Bay is recreated through new interpretations of the lower Bay’s fjordal geomorphology, late Quaternary geology and its ethnographic landscape. Geological interpretation is enhanced by 38 radiocarbon dates compiled from published and unpublished sources, as well as 15 newly dated samples. Neoglacial changes in ice positions, outwash and lake extents are reconstructed for c. 5500–200 cal. yr ago, and portrayed as a set of three landscapes at 1600–1000, 500–300 and 300–200 cal. yr ago. This history reveals episodic ice advance towards the Bay mouth, transforming it from a fjordal seascape into …


Judgments Of Omitted Be And Do In Questions As Extended Finiteness Clinical Markers Of Sli To Fifteen Years: A Study Of Growth And Asymptote, Mabel L. Rice, Lesa Hoffman, Ken Wexler Jan 2009

Judgments Of Omitted Be And Do In Questions As Extended Finiteness Clinical Markers Of Sli To Fifteen Years: A Study Of Growth And Asymptote, Mabel L. Rice, Lesa Hoffman, Ken Wexler

Department of Psychology: Faculty Publications

Purpose—Clinical grammar markers are needed for children with SLI older than 8 years. This study followed children studied earlier on sentences with omitted finiteness to determine if affected children continue to perform at low levels and to examine possible predictors of low performance. This is the first longitudinal report of grammaticality judgments of questions.

Method—Three groups of children participated: 20 SLI, 20 age controls and 18 language-matched controls, followed from ages 6–15 years. An experimental grammaticality judgment task was administered with BE copula/auxiliary and DO auxiliary in Wh- and Yes/No questions for 9 times of measurement. Predictors were indices of …


Children's Behavioral Traits And Risk Of Injury: Analyses From A Case-Control Study Of Agricultural Households, Kathleen F. Carlson, Susan G. Gerberich, Bruce H. Alexander, Ann S. Masten, Timothy R. Church, John M. Shutske, Andrew D. Ryan, Colleen M. Renier Jan 2009

Children's Behavioral Traits And Risk Of Injury: Analyses From A Case-Control Study Of Agricultural Households, Kathleen F. Carlson, Susan G. Gerberich, Bruce H. Alexander, Ann S. Masten, Timothy R. Church, John M. Shutske, Andrew D. Ryan, Colleen M. Renier

United States Public Health Resources

Problem: Children on family agricultural operations have high risk of injury. The association between children's behavioral traits and their risk of injury is not well understood. Method: Data from the Regional Rural Injury Study-II were used to assess behavioral risk factors for injury to children ages six to <20 years. A total of 379 injury events (cases) and 1,562 randomly selected controls were identified. Adjusted odds ratios (OR) and 95% confidence intervals (CI), calculated using logistic regression, were used to estimate injury risk in reference to behavioral traits. Results: Injury risks were greater for children with high levels of depressive symptoms (OR=1.9, CI=1.0-3.7) and aggression (OR=1.6, CI=0.9-2.7), and low levels of careful/cautious behavior (OR=1.8, CI=1.1-2.9). Children with low levels of self-regulation had reduced risks (OR=0.4, CI=0.2-0.8). Discussion: Results suggest that children's behaviors affect their risk of agricultural injury. Additional research …


Review Of Victorian Turns, Neovictorian Returns: Essays On Fiction And Culture, Penny Gay, Judith Johnston, Catherine Waters Jan 2009

Review Of Victorian Turns, Neovictorian Returns: Essays On Fiction And Culture, Penny Gay, Judith Johnston, Catherine Waters

The George Eliot Review Online, ISSN: 2831-5375

The inside of this volume offers exactly the pleasurable variety and range of interest promised by its outside (the beautifully reproduced cover image is Ernest Dudley Heath's Piccadilly Circus at Night, 1893). As its title suggests, the volume, divided into two sections, seeks to capture, in Part One, the diverse ways in which the Victorians explored in fiction the multiple 'turns' in new directions the age was taking, and, in Part Two, the imaginative updatings of these fictions, in literature, film and theatre, as well as in scholarship, in the burgeoning afterlife of Victorianism.

The editors note in their introduction …

Review Of The Moravian Springplace Mission To The Cherokees, Volume I, 1805–1813 And The Moravian Springplace Mission To The Cherokees, Volume Ii, 1814–1821. Edited And With An Introduction By Rowena Mcclinton; Preface By Chad Smith., Angela Pulley Hudson Jan 2009

Review Of The Moravian Springplace Mission To The Cherokees, Volume I, 1805–1813 And The Moravian Springplace Mission To The Cherokees, Volume Ii, 1814–1821. Edited And With An Introduction By Rowena Mcclinton; Preface By Chad Smith., Angela Pulley Hudson

Documentary Editing: Journal of the Association for Documentary Editing (1979–2011)

Noted historian William G. McLoughlin once observed that in addition to mirroring U.S. political structures, the nineteenth-century Cherokee Nation shared two other trends with the young Republic: slavery and Christianity.1 Indeed, even as Cherokee people fought to retain their eastern lands in the first decades of the nineteenth century, they often adopted the ideologies of the land-hungry Americans they tried to resist. Few sources document this complex and contradictory process more vividly than The Moravian Springplace Mission to the Cherokees. Rarely do Cherokee, Christian, and slave histories appear in such intimate relation to one another. In the secondary works on …


The Methodists' Great 1869 Camp Meeting And Aboriginal Conservation Strategies In The North Saskatchewan River Valley, George Colpitts Jan 2009

The Methodists' Great 1869 Camp Meeting And Aboriginal Conservation Strategies In The North Saskatchewan River Valley, George Colpitts

Great Plains Quarterly (through 2013)

George McDougall, chairman of the Methodist Missions to the Indians of the Northwest Territories, kept a large, black book in which he jotted sermon notes, references to classical and biblical literature and sometimes simply his itineraries by horseback from Victoria, the primary Methodist mission in the far British northwest. Under the "s" tab and labeled "Saskatchewan," he noted repeatedly in the 1860s the food crisis facing North Saskatchewan residents. In sum: ''A time of starvation. No buffalo."

In this article I analyze a buffalo hunt which occurred in 1869. That spring, many hundreds of Cree, Assiniboine, Stoney, and Metis hunters …


Thesis As Rhizome: A New Vision For The Honors Thesis In The Twenty-First Century, Kate Briggs Jan 2009

Thesis As Rhizome: A New Vision For The Honors Thesis In The Twenty-First Century, Kate Briggs

Journal of the National Collegiate Honors Council Online Archive

Richly diverse, the collective undergraduate thesis work that students produce across the United States in our honors programs and colleges is cause for celebration of their individual achievements. Generally considered the founder of honors education, Frank Aydelotte centered his honors program model at Swarthmore in the early twentieth century on individual achievement (see Rinn, 2003), which has thus defined honors from the beginning; it is a cardinal honors value, and the thesis is its primary manifestation.


Creative Maladjustment: Engaging Personal Narrative To Teach Diversity And Social Justice, Ilene L. Ingram Jan 2009

Creative Maladjustment: Engaging Personal Narrative To Teach Diversity And Social Justice, Ilene L. Ingram

Journal of Women in Educational Leadership

We all have stories-beautiful and ugly stories-neat ending and never ending stories. When personal narratives, the stories that come closest to the human ex- perience, are used as pedagogy, they can be windows offering views of different worlds and people. In this way, personal narratives become lanterns that illumi- nate the real and imagined fences that divide us as human beings. The intention of this article is to give an account of both how and why I use personal narrative as a pedagogical method to teach diversity and social justice.


Book Review: Queer Inclusions, Continental Divisions: Public Recognition Of Sexual Diversity In Canada And The United States By David Rayside, Karen Busby Jan 2009

Book Review: Queer Inclusions, Continental Divisions: Public Recognition Of Sexual Diversity In Canada And The United States By David Rayside, Karen Busby

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

Queer Inclusions is a fascinating and well-written comparative examination of the politics of sexual diversity in Canada and the United States. David Rayside focuses on how political and legal issues affecting gay and lesbian relationship recognition, parenting, and schooling have played out in these two countries over the last decade. The author, who is not a lawyer, does an excellent job reviewing law reform processes and outcomes in an accurate yet not overly technical manner. His reliance on a variety of methodological techniques makes for a solid, well-tested analysis. In particular, I found his comparative analyses on the influence of …


Book Review: The Arapaho Language By Andrew Cowell, With Alonzo Moss Sr., Neyooxet Greymorning Jan 2009

Book Review: The Arapaho Language By Andrew Cowell, With Alonzo Moss Sr., Neyooxet Greymorning

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

The Arapaho Language is divided into five primary analytical areas on phonology, inflectional morphology, derivational morphology, usage, complex clauses, and syntax. Under these headings an additional 21 subfields and numerous grammatical rules are also provided. One feature that makes this book particularly beneficial is its extensive use of narrative texts, historical accounts, and life experiences of several individuals as examples for discussing how grammatical rules work within the language, which also provides helpful examples of the subtleties, complexity, and flexibility used by Arapaho speakers that differ from other Algonquian languages.

Although it is clear that this book is written primarily …


Book Review: A Grammar Of Crow: Apsáalooke Aliláau By Randolph Graczyk, Rose Chesarek Jan 2009

Book Review: A Grammar Of Crow: Apsáalooke Aliláau By Randolph Graczyk, Rose Chesarek

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

On my desk is an old, unbound manuscript, a hand copy of a Crow grammar written by a Jesuit missionary in the late 1800s. Randolph Graczyk’s A Grammar of Crow: Apsáalooke Aliláau is the first extended grammar of my language since that time. That alone makes it an important contribution to American Indian linguistics and to the study of Crow. It is also a first-class effort. His work is based on a prize-winning dissertation at the University of Chicago, but has been revised and expanded into a general descriptive format to make it accessible to any language scholar interested in …


Chaos Is The Poetry: From Outcomes To Inquiry In Service-Learning Pedagogy, Shari J. Stenberg, Darby Arant Whealy Jan 2009

Chaos Is The Poetry: From Outcomes To Inquiry In Service-Learning Pedagogy, Shari J. Stenberg, Darby Arant Whealy

Department of English: Faculty Publications

It is no secret that the contemporary university values a model of efficiency, of tangible, quantifiable outcomes. Jan Currie and Lesley Vidovich (qtd. in Downing, Hurlbert, Mathieu 9) contend that since the 1980s, the boundaries between higher education, government, and business have largely deteriorated, and business discourse of "excellence" has come to dominate university culture. Consequently, output, outcomes, and efficiency are valorized over and above process, inquiry, and the inevitable tensions of learning. Stanley Aronowitz puts it this way: "[A]cademic leaders chant the mantra of excellence . . . [which] means ... all parts of the university 'perform' and are …


Effects Of Audibility And Multichannel Wide Dynamic Range Compression On Consonant Recognition For Listeners With Severe Hearing Loss, Evelyn Davies-Venn, Pamela Souza, Marc Brennan, G. Christopher Stecker Jan 2009

Effects Of Audibility And Multichannel Wide Dynamic Range Compression On Consonant Recognition For Listeners With Severe Hearing Loss, Evelyn Davies-Venn, Pamela Souza, Marc Brennan, G. Christopher Stecker

Department of Special Education and Communication Disorders: Faculty Publications

Objective—This study examined the effects of multichannel wide-dynamic range compression (WDRC) amplification and stimulus audibility on consonant recognition and error patterns.

Design—Listeners had either severe or mild-to-moderate sensorineural hearing loss. Each listener was monaurally fit with a wearable hearing aid using typical clinical procedures, frequency-gain parameters and a hybrid of clinically prescribed compression ratios for DSL (Scollie et al., 2005) and NAL-NL (Dillon, 1999). Consonant-vowel nonsense syllables were presented in soundfield at multiple input levels (50, 65, 80 dB SPL). Test conditions were four-channel fast-acting WDRC amplification and a control compression limiting (CL) amplification condition. Listeners identified the stimulus heard …


A Nonword Repetition Task For Speakers With Misarticulations: The Syllable Repetition Task (Srt), Lawrence D. Shriberg, Heather L. Lohmeier, Thomas F. Campbell, Christine A. Dollaghan, Jordan R. Green, Christopher A. Moore Jan 2009

A Nonword Repetition Task For Speakers With Misarticulations: The Syllable Repetition Task (Srt), Lawrence D. Shriberg, Heather L. Lohmeier, Thomas F. Campbell, Christine A. Dollaghan, Jordan R. Green, Christopher A. Moore

Department of Special Education and Communication Disorders: Faculty Publications

Purpose. Conceptual and methodological confounds occur when non(sense) repetition tasks are administered to speakers who do not have the target speech sounds in their phonetic inventories or who habitually misarticulate targeted speech sounds. We describe a nonword repetition task, the Syllable Repetiton Task (SRT) that eliminates this confound and report findings from three validity studies.
Method. Ninety-five preschool children with Speech Delay and 63 with Typical Speech, completed an assessment battery that included the Nonword Repetition Task (NRT: Dollaghan & Campbell, 1998) and the SRT. SRT stimuli include only four of the earliest occurring consonants and …


The Willa Cather Archive In The Classroom, Andrew Jewell Jan 2009

The Willa Cather Archive In The Classroom, Andrew Jewell

University of Nebraska-Lincoln Libraries: Faculty Publications

This essay discusses many of the opportunities for teachers I believe are present in the Willa Cather Archive (http://cather.unl.edu), particularly in the way the Archive makes new materials available or older materials available in a new way. Additionally, this essay suggests some of the implications of the Archive’s digital presentation of resources. However, the place of digital scholarship in academic life is still evolving, and students and teachers are just getting accustomed to using the form. Given this circumstance, many of my thoughts are inconclusive, observations based upon preliminary understandings into how this resource affects our classrooms. I avoid confident …


Using Hlm To Analyze On-Going Teacher Professional Development And Implementation Of Scientific Classroom Discourse Community Strategies, Elizabeth B. Lewis, Dale R. Baker, Brandon Helding, Michael Lang Jan 2009

Using Hlm To Analyze On-Going Teacher Professional Development And Implementation Of Scientific Classroom Discourse Community Strategies, Elizabeth B. Lewis, Dale R. Baker, Brandon Helding, Michael Lang

Department of Teaching, Learning, and Teacher Education: Presentations

One-hundred-and-sixty classroom observations of secondary science and language arts teachers were made throughout the 2007-2008 academic year to determine the extent of their use of professional development, specifically using strategies to construct a scientific classroom discourse community (SCDC). Each observation was scored using a 36-item instrument of various SCDC instructional strategies designed to match the professional development. These observation scores and teacher demographic information were used to build a hierarchical linear model to explore for statistically significant relationships over time. The length of time that the teachers received professional development was chosen as the exclusive predictor of teacher change because …


Intergenerational Spanish Transmission In El Paso, Texas: Parental Perceptions Of Cost/Benefit, M. Isabel Velázquez Jan 2009

Intergenerational Spanish Transmission In El Paso, Texas: Parental Perceptions Of Cost/Benefit, M. Isabel Velázquez

Spanish Language and Literature Papers

This study examines the beliefs held by a group of adult Spanish-English bilinguals from El Paso, Texas, regarding the vitality of Spanish in their community and the ways in which their own experience of being bilingual on the US-Mexico border has influenced their perceptions of the benefits and costs of fostering Spanish development in their children. Results show that parents’ positive attitudes toward Spanish did not translate into the investment of time and resources to foster Spanish development in their children nor, ultimately, into the use of Spanish by their children. Households where the mother perceived herself as having an …

An evidence-based methodology was adopted in this research to establish strategies to increase lead recovery and recycling via a systematic review and critical appraisal of the published literature. In particular, the research examines pollution prevention and waste minimization practices and technologies that meet the following criteria: (a) reduce/recover/recycle the largest quantities of lead currently being disposed of as waste, (b) technically and economically viable, that is, ready to be diffused and easily transferable, and (c) strong industry interest (i.e., industry would consider implementing projects with higher payback periods). The following specific aims are designed to achieve the study objectives: Aim …


The Dynamics Of Development: Challenges For Bayesian Rationality, Nils Straubinger, Edward T. Cokely, Jeffrey R. Stevens Jan 2009

The Dynamics Of Development: Challenges For Bayesian Rationality, Nils Straubinger, Edward T. Cokely, Jeffrey R. Stevens

Department of Psychology: Faculty Publications

Commentary on Oaksford & Chater, Precis of Bayesian Rationality

Oaksford & Chater draw a rather static picture of human reasoning by focusing on typical patterns of responses from adults. We propose a more dynamic perspective, which considers that reasoning systematically varies within individuals over the lifespan (Howe & Rabinowitz 1996; Markovits & Barrouillet 2002) and between individuals with different levels of knowledge and expertise (Ericsson et al. 2006).

The original articles, the full set of commentaries, and the authors' response are attached (below) as an "Additional file."


The Essentials Of Vocabulary Teaching: From Theory To Practice, Aleidine Kramer Moeller, Olha Ketsman, Leyla Masmaliyeva Jan 2009

The Essentials Of Vocabulary Teaching: From Theory To Practice, Aleidine Kramer Moeller, Olha Ketsman, Leyla Masmaliyeva

Department of Teaching, Learning, and Teacher Education: Faculty Publications

Vocabulary is central to the learning and teaching of a second language as it affords learners access to all forms of oral and written communication that includes literature, music, and content knowledge. Word knowledge is power as words serve as building blocks to learning. Vocabulary building often occurs through reading; however, in the foreign language classroom due to the heavy concept load involved in reading a second language it is unlikely that students will acquire the essential vocabulary needed to comprehend the content and information they encounter in many texts. One of the major roles of the teacher then becomes …


“Re-Culturing” Teacher Education: Inquiry, Evidence, And Action, Marilyn Cochran-Smith, Boston College Evidence Team Jan 2009

“Re-Culturing” Teacher Education: Inquiry, Evidence, And Action, Marilyn Cochran-Smith, Boston College Evidence Team

Department of Teaching, Learning, and Teacher Education: Faculty Publications

Currently the press to make policy and practice decisions on the basis of evidence is being coupled with recognition that real change requires shifts in organizational culture. Consequently, there are now many efforts to “re-culture” organizations by making evidence central to decision making. In this article, the authors problematize the notion of a “culture of evidence” in teacher education. Then the article identifies four key aspects involved in efforts to create a culture of evidence at one institution over a five-year period: (1) development of a portfolio of studies about processes and outcomes; (2) recognition that teacher education always poses …


Agreement Answer Scale Design For Multilingual Surveys: Effects Of Translation-Related Changes In Verbal Labels On Response Styles And Response Distributions, Ana Villar Jan 2009

Agreement Answer Scale Design For Multilingual Surveys: Effects Of Translation-Related Changes In Verbal Labels On Response Styles And Response Distributions, Ana Villar

Survey Research and Methodology Program: Dissertations, Theses, and Student Research

Answer scales in survey instruments are widely used, but little is known about how to choose verbal descriptors as labels. In multilingual research, this matter is further complicated because answer scales must be appropriate for all languages and function comparatively. Comparing source questionnaires to translations of multinational projects (e.g., the World Values Survey, the European Social Survey), it was observed that certain verbal features differed across languages, countries, and modules. This dissertation empirically investigates the effect of such changes on response distributions. The verbal feature examined is the presence or absence of an intensity modifier in the second and fourth …


Patriarchy, Michael R. Hill Jan 2009

Patriarchy, Michael R. Hill

Department of Sociology: Faculty Publications

The term patiarchy refers to an organization, institution, or society in which power, social control, material wealth, and high social status accrue predominantly to males rather than females. Patriarchy is one of the most enduring and pervasive of all social patterns. It appears in all eras, among all races, social institutions, and economic classes, and in virtually every known culture. Rising initially in early family and kinship structures, hierarchical patriarchal patterns are found today around the globe not only in family and kinship groups but also throughout the major social institutions, including language, family, economy, polity, religion, law, education, science, …


An Overview Of Historical Beaver Management In Arizona, Christopher Carrillo, David Bergman, Jimmy D. Taylor Ii, Dale L. Nolte, Patrick Viehoever, Mike Disney Jan 2009

An Overview Of Historical Beaver Management In Arizona, Christopher Carrillo, David Bergman, Jimmy D. Taylor Ii, Dale L. Nolte, Patrick Viehoever, Mike Disney

United States Department of Agriculture Wildlife Services: Staff Publications

In the mid-1820s, Anglo-American fur trappers, known as "mountain men," entered Arizona and began trapping beaver (Castor canadensis). In Arizona there have been a number of famous mountain men such as Sylvester and James Pattie, Ewing Young, Jededia Smith, and Bill Williams who trapped along the waterways in northern and southern Arizona. Although the heyday of mountain men lasted only a few decades due to a population decline of beaver, management of these animals continues to this day. The purpose of managing beavers shifted from monetary gain to controlling wildlife damage. During the late 1900s, beaver were still …


An Adaptive Steganography Scheme For Voice Over Ip, Hui Tian, Ke Zhou, Hong Jiang, Yongfeng Huang, Jin Liu, Dan Feng Jan 2009

An Adaptive Steganography Scheme For Voice Over Ip, Hui Tian, Ke Zhou, Hong Jiang, Yongfeng Huang, Jin Liu, Dan Feng

School of Computing: Conference and Workshop Papers

This paper presents an adaptive steganography scheme for Voice over IP (VoIP). Differing from existing steganography techniques for VoIP, this scheme enhances the embedding transparency by taking into account the similarity between Least Significant Bits (LSBs) and embedded messages. Moreover, we introduce the notion of Partial Similarity Value (PSV). By properly setting the threshold PSV, we can adaptively balance the embedding transparency and capacity. We evaluate the effectiveness of this scheme with G.729a as the codec of the cover speech in StegTalk, a covert communication system based on VoIP. The experimental results demonstrate that our technique provides better performance than …

Xenophobia: Understanding The Roots And Consequences Of Negative Attitudes Toward Immigrants, Oksana Yakushko Jan 2009

Xenophobia: Understanding The Roots And Consequences Of Negative Attitudes Toward Immigrants, Oksana Yakushko

Department of Educational Psychology: Faculty Publications

The current xenophobic cultural environment in the United States makes it imperative that psychologists understand the nature of xenophobia and recognize its consequences. This article explores sociological, social psychological, and multicultural research to examine the causes of negative attitudes toward immigrants. Xenophobia is presented as a concept descriptive of a socially observable phenomenon. Historical and contemporary expressions of xenophobia in the United States are examined and compared with cross-cultural scholarship on negative attitudes toward immigrants. Last, suggestions are provided for how counseling psychologists can integrate an understanding of xenophobia into their clinical practice, training, research, and public policy advocacy.


"Israel": An Abstract Concept Or Concrete Reality In Recent Judeo-Argentinean Narrative?, Amalia Ran Jan 2009

"Israel": An Abstract Concept Or Concrete Reality In Recent Judeo-Argentinean Narrative?, Amalia Ran

Spanish Language and Literature Papers

The re-democratization process in Argentina, beginning at the end of 1983, emphasized a tendency that had emerged within the Judeo-Argentinean fiction (and Argentinean narrative in general) to contemplate on the collective and personal memory, while creating a type of dialogue with the general historic context of the twentieth century. This process was un-masqueraded as a political and literary strategy in order to re-create an "archive" and re-construct it in a way that would correspond to the new material circumstances of the Argentinean nation and its society at that specific moment. The dilemma of how to define the essence of Jewish …
