Incorporating Social Anxiety Into A Model Of College Problem Drinking: Replication And Extension, Lindsay S. Ham, Debra A. Hope Jan 2006

Incorporating Social Anxiety Into A Model Of College Problem Drinking: Replication And Extension, Lindsay S. Ham, Debra A. Hope

Department of Psychology: Faculty Publications

Although research has found an association between social anxiety and alcohol use in noncollege samples, results have been mixed for college samples. College students face many novel social situations in which they may drink to reduce social anxiety. In the current study, the authors tested a model of college problem drinking, incorporating social anxiety and related psychosocial variables among 228 undergraduate volunteers. According to structural equation modeling (SEM) results, social anxiety was unrelated to alcohol use and was negatively related to drinking consequences. Perceived drinking norms mediated the social anxiety–alcohol use relation and was the variable most strongly associated with …


“You Can’T Hustle All Your Life”: An Exploratory Investigation Of The Exit Process Among Street-Level Prostituted Women, Rochelle L. Dalla Jan 2006

“You Can’T Hustle All Your Life”: An Exploratory Investigation Of The Exit Process Among Street-Level Prostituted Women, Rochelle L. Dalla

Department of Child, Youth, and Family Studies: Faculty Publications

Between 1998 and 1999, 43 street-level prostituted women were interviewed regarding their developmental experiences, including prostitution entry, maintenance, and exit attempts. Three years later, 18 of the original 43 participants were located and interviewed. This exploratory follow-up investigation focused on the women’s life experiences between the two points of contact, with emphasis on sex-industry exit attempts. Five women had maintained their exit efforts and had not returned to prostitution, nine had returned to both prostitution and drug use, and one had returned to prostitution only. Three additional women had violated parole and been reincarcerated. Themes evident among those who were …


Critical Analysis Of Coprolite Evidence Of Medicinal Plant Use, Piauí, Brazil, Sérgio Augusto De Miranda Chaves, Karl J. Reinhard Jan 2006

Critical Analysis Of Coprolite Evidence Of Medicinal Plant Use, Piauí, Brazil, Sérgio Augusto De Miranda Chaves, Karl J. Reinhard

Department of Anthropology: Faculty Publications

Human coprolites, dating from 8,500 to 7,000 years BP, were collected from the rock-shelter of Boqueirão da Pedra Furada, in Piauí, Brazil. These dates fall within the “Serra Talhada” cultural traditions I and II of the Tradição Nordeste, a paleohuman culture of northeastern Brazil. Archaeoparasitological analysis of the coprolites revealed whipworm eggs and hookworm eggs. Analysis of Tradição Nordeste skeletons and hair shows a variety of diseases including dental problems, osteoarthritis, and head louse infestation. Palynological analysis of the coprolites revealed 12 genera that were potentially medicinal. The pollen data were critically analyzed to assess the potentiality that the pollen …

Bio-Bibliography: John Barron Mays (1914-1987), Michael R. Hill Jan 2006

Bio-Bibliography: John Barron Mays (1914-1987), Michael R. Hill

Department of Sociology: Faculty Publications

John Barron Mays developed a humane sociological perspective with multiple roots, including formal training in English, firsthand experience in a settlement house, a distinguished university professorship in sociology, and lifelong work as an active poet. Mays’ felicitous professional publications often spoke not only to university colleagues but also to constituencies beyond the halls of academe on a series of interrelated topics, including adolescence, criminology, education, urban life, and poetry.


Theory, Values, And Practice In The Legal Lifeworld Of Sociological Jurisprudence: Roscoe Pound’S Views On Professional Women, Michael R. Hill Jan 2006

Theory, Values, And Practice In The Legal Lifeworld Of Sociological Jurisprudence: Roscoe Pound’S Views On Professional Women, Michael R. Hill

Department of Sociology: Faculty Publications

The lived social dimensions of Roscoe Pound’s theories of sociological jurisprudence deserve criticism in light of his often progressive worldview and frequent support of civil liberties. Especially important in this regard are his views on women. Despite Sayre’s (1948: 390) assertion that “there is no dualism to Pound,” the archival record reveals internal contradictions. That is to say, Pound’s attitudes toward women were multi-dimensional. His social attitudes-inpractice informed his sociological ideas and thus illustrate the lived conflicts in his professional lifeworld.


Children’S Social Behaviors And Peer Interactions In Diverse Cultures, Carolyn P. Edwards, Maria Deguzman, Jill Brown, Asiye Kumru Jan 2006

Children’S Social Behaviors And Peer Interactions In Diverse Cultures, Carolyn P. Edwards, Maria Deguzman, Jill Brown, Asiye Kumru

Department of Psychology: Faculty Publications

This chapter lays out five principles to guide research on peer relationships in cultural context that reflect both current and earlier bodies of research literature: (1) Cultural scripts for socialization in peer relationships are evident in early childhood. (2) Both across and within cultural communities, children’s own active role in the socialization process becomes increasingly evident as they grow older. (3) Because children are active agents in their own socialization, they can not only make choices, they can also negotiate, deflect, and resist socializing attempts by others. (4) Children’s choices and preferences (self-socialization) during middle childhood have measurable and lasting …

Involvement In Early Head Start Home Visiting Services: Demographic Predictors And Relations To Child And Parent Outcomes, Helen Raikes, Beth L. Green, Jane Atwater, Ellen Kisker, Jill Constantine, Rachel Chazan-Cohen Jan 2006

Involvement In Early Head Start Home Visiting Services: Demographic Predictors And Relations To Child And Parent Outcomes, Helen Raikes, Beth L. Green, Jane Atwater, Ellen Kisker, Jill Constantine, Rachel Chazan-Cohen

Department of Child, Youth, and Family Studies: Faculty Publications

One strand of home visiting research investigates effi cacy while another investigates under what conditions programs achieve outcomes. The current study follows the latter approach. Using a within-program design in a sample of 11 home-based sites in the Early Head Start Research and Evaluation study, this study found that three components of home visits (quantity of involvement including number of home visits, duration in the program, length of visits and intensity of service; quality of engagement including global ratings of engagement by staff and ratings of engagement during each home visit; and the extent to which home visits were child …


Child Care For Children With And Without Disabilities: The Provider, Observer, And Parent Perspectives, Lisa Knoche, Carla A. Peterson, Carolyn P. Edwards, Hyun-Joo Jeon Jan 2006

Child Care For Children With And Without Disabilities: The Provider, Observer, And Parent Perspectives, Lisa Knoche, Carla A. Peterson, Carolyn P. Edwards, Hyun-Joo Jeon

Department of Child, Youth, and Family Studies: Faculty Publications

This three-phase study, part of a larger study conducted by the Midwest Child Care Research Consortium (MCCRC), investigated the characteristics of child care providers in inclusive and non-inclusive center-based classrooms and family child care homes, the observed quality of care in a subset of these programs, and families’ perceptions of quality and satisfaction with child care services. A telephone survey of 2022 randomly selected Midwestern providers, 36% of whom provided inclusive services, revealed that inclusive providers rated themselves higher on most quality-related indicators. Inclusion status was related to observed quality in family childcare homes (n = 132), with non-inclusive homes …


Influences Of Management Regimes On Breeding Bird Densities And Habitat In Mixed-Grass Prairie: An Example From North Dakota, Andrea A. Lueders, Patricia L. Kennedy, Douglas H. Johnson Jan 2006

Influences Of Management Regimes On Breeding Bird Densities And Habitat In Mixed-Grass Prairie: An Example From North Dakota, Andrea A. Lueders, Patricia L. Kennedy, Douglas H. Johnson

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

It is well known that North American grassland bird populations appear to be declining (Igl and Johnson 1997, Sauer et al. 2004). Most of these birds breed and winter in North America, so declines are likely associated with continental processes (Knopf 1994). Scientists have also observed parallel declines among species that have overlapping breeding ranges but disparate wintering distributions (Igl and Johnson 1997). These patterns suggest declines may be linked to problems on the breeding grounds.


Patch Size And Landscape Effects On Density And Nesting Success Of Grassland Birds, Maiken Winter, Douglas H. Johnson, Jill A. Shaffer, Therese M. Donovan, W. Daniel Svedarsky Jan 2006

Patch Size And Landscape Effects On Density And Nesting Success Of Grassland Birds, Maiken Winter, Douglas H. Johnson, Jill A. Shaffer, Therese M. Donovan, W. Daniel Svedarsky

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

Cumnt management recommendations for grassland birds in North America emphasize providing large patches of grassland habitat within landscapes that have few forest or shrubland areas. These Bird Conservation Areas are being proposed under the assumption that large patches of habitat in treeless landscapes will maintain viable populations of grassland birds. This assumption requires that patch size and landscape features affect density and nesting success of grassland birds, and that these effects are consistent among years and regions and across focal species. However, these assumptions have not yet been validated for grassland binls, and the relative importance of local vegetation structure, …


Urine-Marking And Ground-Scratching By Free-Ranging Arctic Wolves, Canis Lupus Arctos, In Summer, L. David Mech Jan 2006

Urine-Marking And Ground-Scratching By Free-Ranging Arctic Wolves, Canis Lupus Arctos, In Summer, L. David Mech

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

Urine-marking and ground-scratching were observed in an Arctic Wolf (Canis lupus) pack on Ellesmere Island, Nunavut, Canada, during 16 summers between 1986 and 2005. All previously known urination postures and ground-scratching by breeding males and females were seen, and incidence of marking and scratching was greatest when non-pack wolves were present. Observations of urine-marking of food remains supported the conclusion from a captive Wolf study that such marking signals lack of edible food.


Are Trans-Pacific Invasions The New Wave?, Ragan M. Callaway, Shi Li Miao, Qinfeng Guo Jan 2006

Are Trans-Pacific Invasions The New Wave?, Ragan M. Callaway, Shi Li Miao, Qinfeng Guo

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

The movement of organisms among continents by humans has caused profound changes in the ecology of relocated species and of communities to which they have been introduced. Perhaps less than 1% of all species that arrive at foreign shores become invaders (Williamson and Fitter 1996), but the few that explode in abundance wreak tremendous environmental and economic damage (Mack et al. 2000; Pimentel et al. 2000; Xu et al. 2006). During the last decade research on invasive species has dramatically increased. For example, from 1988 to 1990 the journal Ecology published three papers with the words ‘invasive’ or ‘invader’ in …


Mallard Brood Movements, Wetland Use, And Duckling Survival During And Following A Prairie Drought, Gary L. Krapu, Pamela J. Pietz, David A. Brandt, Robert R. Cox Jr. Jan 2006

Mallard Brood Movements, Wetland Use, And Duckling Survival During And Following A Prairie Drought, Gary L. Krapu, Pamela J. Pietz, David A. Brandt, Robert R. Cox Jr.

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

We used radiotelemetry to study mallard (Anas platyrhynchos) brood movements, wetland use, and duckling survival during a major drought (1988–1992) and during the first 2 years of the subsequent wet period (1993–1994) at 4 51-km2 sites in prairie pothole landscapes in eastern North Dakota, USA. About two-thirds of 69 radiomarked mallard broods initiated moves from the nest to water before noon, and all left the nest during daylight. On average, broods used fewer wetlands, but moved greater distances during the dry period than the wet period. Broods of all ages were more likely to make inter-wetland moves …


Prediction Failure Of A Wolf Landscape Model, L. David Mech Jan 2006

Prediction Failure Of A Wolf Landscape Model, L. David Mech

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

I compared 101 wolf (Canis lupus) pack territories formed in Wisconsin during 1993–2004 to the logistic regression predictive model of Mladenoff et al. (1995, 1997, 1999). Of these, 60% were located in putative habitat suitabilities 50% remained unoccupied by known packs after 24 years of recolonization. This model was a poor predictor of wolf re-colonizing locations in Wisconsin, apparently because it failed to consider the adaptability of wolves. Such models should be used cautiously in wolf-management or restoration plans.

Bio-Bibliography: William Clark Gordon (1865-1936), Michael R. Hill Jan 2006

Bio-Bibliography: William Clark Gordon (1865-1936), Michael R. Hill

Department of Sociology: Faculty Publications

William Clark Gordon was a clergyman and an early theorist of the relationships between literature and sociology. He earned a Ph.D. in the University of Chicago Divinity School in 1899 where he majored — within the School’s own Department of Sociology — in social institutions. As such, he completed his doctorate during the first full decade of Chicago’s pioneering sociological project — a fact noted but misattributed by Robert E. L. Faris (1967) to work in the University’s Department of Sociology in the Graduate School of Arts and Literature (Hill 2005). As a practicing clergyman, Gordon’s professional attentions focused on …


Effects Of Using Visual Design Principles To Group Response Options In Web Surveys, Jolene D. Smyth, Don A. Dillman, Leah M. Christian, Michael J. Stern Jan 2006

Effects Of Using Visual Design Principles To Group Response Options In Web Surveys, Jolene D. Smyth, Don A. Dillman, Leah M. Christian, Michael J. Stern

Department of Sociology: Faculty Publications

In this paper, we show that in Web questionnaires verbal and visual languages can be used to create groups and subgroups of information, which influence how respondents process Web questionnaires. Following Schwarz (1996; and also Schwarz, Grayson, & Knäuper, 1998) we argue that respondents act as cooperative communicators who use formal features of the questionnaire to help guide them through the survey conversation. Using data from three Web surveys of random samples of Washington State University undergraduates, we found that when response options are placed in close graphical proximity to each other and separated from other options, respondents perceive visual …


Mental Disorders Among Parents/Caretakers Of American Indian Early Adolescents In The Northern Midwest, Les B. Whitbeck, Dan R. Hoyt, Kurt Johnson, Xiaojin Chen Jan 2006

Mental Disorders Among Parents/Caretakers Of American Indian Early Adolescents In The Northern Midwest, Les B. Whitbeck, Dan R. Hoyt, Kurt Johnson, Xiaojin Chen

Department of Sociology: Faculty Publications

Background: This study reports prevalence and comorbidty of five DSM-III-R diagnoses (alcohol abuse, alcohol dependence, drug abuse, major depressive episode, and generalized anxiety disorder) among American Indian and Canadian First Nations parents/caretakers of children aged 10–12 years from the Northern Midwest United States and Canada. Lifetime prevalence rates were compared to adults in the National Comorbidity Survey (NCS) and Southwest and Northern Plains cultures from the AI-SUPERPFP study.

Method: Native interviewers used computer-assisted personal interviews to administer the University of Michigan Composite International Diagnostic Interview (UM-CIDI) to 861 tribally enrolled parents and caretakers (625 females; 236 males) of 741 tribally …


Mental Disorders, Comorbidity, And Postrunaway Arrests Among Homeless And Runaway Adolescents, Xiaojin Chen, Lisa Thrane, Les B. Whitbeck, Kurt Johnson Jan 2006

Mental Disorders, Comorbidity, And Postrunaway Arrests Among Homeless And Runaway Adolescents, Xiaojin Chen, Lisa Thrane, Les B. Whitbeck, Kurt Johnson

Department of Sociology: Faculty Publications

This study examined the associations between lifetime mental disorder, comorbidity, and self-reported postrunaway arrests among 428 (187 males, 241 females) homeless and runaway youth. The analysis examined the pattern of arrests across five lifetime mental disorders (alcohol abuse, drug abuse, conduct disorder, major depressive episode, and posttraumatic stress disorder). The adolescents, ranging from 16 to 19 years old, were interviewed directly on the streets and in shelters in four Midwestern states using computer-assisted personal interviewing. Extensive self-reports of early life history, behaviors since running away from home, and diagnostic interviewing (UM-CIDI and DISC-R) were used to estimate possible disorders. There …


Examining The Changing Influence Of Predictors On Adolescent Alcohol Misuse, Kimberly A. Tyler, Rosalie Torres Stone, Bianca Bersani Jan 2006

Examining The Changing Influence Of Predictors On Adolescent Alcohol Misuse, Kimberly A. Tyler, Rosalie Torres Stone, Bianca Bersani

Department of Sociology: Faculty Publications

The purpose of this study was to examine whether the influence of key characteristics on adolescent alcohol misuse (is., maternal binge drinking, parenting, peers, school characteristics, and the adolescent's own behavior) change over time and whether predictors of adolescent alcohol misuse vary by gender and race/ethnicity. Using prospective, longitudinal data from a community sample, results revealed that mother's hinge drinking, peer drinking, and an early age of onset predicted higher levels of alcohol misuse when respondents were 14-16 years of age. Two years later, when adolescents were 16- 18 years of age, maternal binge drinking was no longer significant, however, …


The Impact Of Support Received And Support Provision On Changes In Perceived Social Support Among Older Adults, Kimberly A. Tyler Jan 2006

The Impact Of Support Received And Support Provision On Changes In Perceived Social Support Among Older Adults, Kimberly A. Tyler

Department of Sociology: Faculty Publications

The current study uses longitudinal data from the 1993 U.S. Midwest floods to examine the influence of support received and support provision on changes in perceived social support among older adults exposed to an acute stressor. Results indicated that flood exposure and higher levels of social support at Time 1 were positively associated with both receiving social support and providing social support specific to the food. Individuals with higher levels of support provision and received support in turn reported higher levels of perceived support post disaster. Women were more likely to have received flood specific support and to have perceived …

The Problem Of Secular Sacredness: Ronald Dworkin, Michael Perry, And Human Rights Foundationalism, Ari Kohen Jan 2006

The Problem Of Secular Sacredness: Ronald Dworkin, Michael Perry, And Human Rights Foundationalism, Ari Kohen

Department of Political Science: Faculty Publications

The concept of human rights ultimately rests on the premise that there are some things that ought to be done for human beings and other things that ought not to be done to human beings in light of the fact that they are human. According to the Universal Declaration of Human Rights, these rights stem from the “recognition of the inherent dignity and of the equal and inalienable rights of all members of the human family” (Ishay 1997: 407). Some would argue that this notion has its roots in the natural law and natural rights tradition that is an important …


North American Prairie Wetlands Are Important Nonforested Land-Based Carbon Storage Sites, Ned H. Euliss Jr., R. A. Gleason, A. Olness, R.L. Mcdougal, H.R. Murkin, R.D. Robarts, R.A. Bourbonniere, B.G. Warner Jan 2006

North American Prairie Wetlands Are Important Nonforested Land-Based Carbon Storage Sites, Ned H. Euliss Jr., R. A. Gleason, A. Olness, R.L. Mcdougal, H.R. Murkin, R.D. Robarts, R.A. Bourbonniere, B.G. Warner

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

We evaluated the potential of prairie wetlands in North America as carbon sinks. Agricultural conversion has resulted in the average loss of 10.1 Mg ha- of soil organic carbon on over 16 million ha of wetlands in this region. Wetland restoration has potential to sequester 378 Tg of organic carbon over a 10-year period. Wetlands can sequester over twice the organic carbon as no-till cropland on only about 17% of the total land area in the region. We estimate that wetland restoration has potential to offset 2.4% of the annual fossil CO2 emission reported for North America in …


Intercontinental Biotic Invasions: What Can We Learn From Native Populations And Habitats?, Qinfeng Guo Jan 2006

Intercontinental Biotic Invasions: What Can We Learn From Native Populations And Habitats?, Qinfeng Guo

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

The effectiveness of management strategies for invasive species is often hampered by a lack of clear understanding of the factors that limit species distributions. The distribution of exotic species, especially those that are invasive, are often so dynamic that limiting factors are difficult to identify. Comparisons of exotic species between their native ranges, where they are presumably close to equilibrium with controlling factors, and their ranges in areas of introduction can circumvent this difficulty. Such studies would help identify (1) limiting factors for distributions in native ranges, (2) factors associated with a high degree of invasiveness, (3) changes in genetics …
