An Examination Of Female Youth Gangs, Tiffiney Y. Barfield-Cottledge, Myrna Cintron, Jonathan Sorensen

Contemporary Issues in Juvenile Justice

Cohen's subculture of delinquency theory (1955) posits that male youth gangs exist largely as the result of the status frustration experienced by rejected adolescents in their search for middle class acceptance. Cohen concluded that social and structural factors, particularly neighborhood and school environments, impacted youth gang prevalence. While many studies related to the existence of youth gangs have been conducted, few have focused specifically on female youth gangs. In the current study, an examination of female youth gangs was conducted using self-report data gathered for the National Longitudinal Survey of Youth (1997-2001). Contrary to arguments that gendered-specific criminological theories are …

Literature Review Of Mule Deer And White-Tailed Deer Movements In Western And Midwestern Landscapes, Scott E. Hygnstrom, Scott R. Groepper, Kurt C. Vercauteren, Chuck J. Frost, Justin R. Boner, Travis C. Kinsell, Gregory M. Clements

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

The relationships among seasonal change, population dynamics, social pressures, landscape dynamics, anthropologic disturbances, and behavioral ecology are complex. Therefore, migration and seasonal movements are poorly understood and dispersal continues to be one of the least understood aspects of animal ecology in North America. We reviewed scientific literature on movements of mule deer (Odocoileus hemionus) and white-tailed deer (O. virginianus) in western and midwestern landscapes to identify gaps in our knowledge and direct future research. We used electronic databases, library catalogs, Internet search engines, and peer-reviewed journals to conduct key word searches for pertinent articles. We found …

Engineer Cantonment, Missouri Territory, 1819-1820: America's First Biodiversity Ineventory, Hugh H. Genoways, Brett C. Ratcliffe

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

It is our thesis that members of the Stephen Long Expedition of 1819-20 completed the first biodiversity inventory undertaken in the United States at their winter quarters, Engineer Cantonment, Missouri Territory, in the modern state of Nebraska. This accomplishment has been overlooked both by biologists and historians, but it should rank among the most significant accomplishments of the expedition. The results of this inventory allow us to evaluate the environmental, faunal, and floral changes along the Missouri River in the intervening nearly 190 years. The historical records form a visual image of a dynamic riverine system in which a highly …

Mapping Agricultural Land Cover For Hydrologic Modeling In The Platte River Watershed Of Nebraska, Patti R. Dappen, Ian C. Ratcliffe, Cullen R. Robbins, James W. Merchant

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

Throughout the western United States, natural resources managers are attempting to address the growing, and often competing, demands that municipal, agricultural and environmental interests have for water. The Platte River Cooperative Hydrology Study (COHYST) is a multi-agency effort that seeks to improve understanding of the ecology, geology, and hydrology of the Platte River watershed in central and western Nebraska. Information regarding the types, areal extent, and locations of crops (especially irrigated crops) is critical for estimating consumptive use of water. Digital land-cover and land-use datasets of the central and western Platte River valley have been prepared for four years: 1982, …

Earthworm Abundances In Endophyte-Infected Tall Fescue Pastures In Northwest Arkansas, Ashley Rashe, Mary C. Savin

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

The ecology of organisms that co-evolve within an ecosystem is likely to be distinct from that involving organisms recently introduced into an area. To better understand the relationship of earthworms with endophyte-infected tall fescue, earthworms in novel and toxic endophyte-infected tall fescue pastures were enumerated and identified as adults or juveniles. We hypothesized that differences in endophyte infection of the fescue would influence earthworm abundances. Earthworms in two toxic and two novel endophyte-infected tall fescue fields in Fayetteville, Ark., were sampled weekly from January through July 2007. Each type of endophyte-infected pasture was established in 1997 and 2003. Sampling was …

Lung Cancer Mortality Is Elevated In Coal Mining Areas Of Appalachia, Michael Hendryx, Kathryn O'Donnell, Kimberly Horn

Regional Research Institute Working Papers

Previous research has documented increased lung cancer incidence and mortality in Appalachia. The current study tests whether residence in coal mining areas of Appalachia is a contributing factor. We conducted a national county-level analysis to identify contributions of smoking rates, socioeconomic variables, coal mining intensity and other variables to age-adjusted lung cancer mortality. Results demonstrate that lung cancer mortality for the years 2000-2004 is higher in areas of heavy Appalachian coal mining after adjustments for smoking, poverty, education, age, sex, race and other covariates. Higher mortality may be the result of exposure to environmental contaminates associated with the coal mining …

Wolf Body Mass Cline Across Minnesota Related To Taxonomy?, L. David Mech, William J. Paul

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

Recent genetic studies suggest that in northern Minnesota two species of wolves (Canis lupus L., 1758 or western wolf and Canis lycaon Schreber, 1775 (= Canis rufus Audubon and Bachman, 1851) or eastern wolf) meet and hybridize. However, little morphological information is available about these two types of wolves in Minnesota. We analyzed the mass of 950 female wolves and 1006 males older than 1 year from across northern Minnesota and found that it increased from 26.30 ± 0.56 kg (mean ± SE) for females and 30.60 ± 0.72 kg for males in northeastern Minnesota to 30.01 ± 0.43 …

A Two-Part Measure Of Degree Of Invasion For Cross-Community Comparisons, Qinfeng Guo, Amy Symstad

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

Invasibility is a critical feature of ecological communities, especially for management decisions. To date, invasibility has been measured in numerous ways. Although most researchers have used the richness (or number) of exotic species as a direct or indirect measure of community invasibility, others have used alternative measures such as the survival, density, or biomass of either a single or all exotic species. These different measures, even when obtained from the same communities, have produced inconsistent results and have made comparisons among communities difficult. Here, we propose a measure of the degree of invasion (DI) of a community as a surrogate …

Parasite Pathoecology Of Salmon Pueblo And Other Chacoan Great Houses: The Healthiest And Wormiest Ancestral Puebloans, Karl Reinhard

Karl Reinhard Publications

Two fields of paleopathological investigation originated in the Southwest. Archaeoparasitology is the study of ancient parasite infection (Reinhard 1990, 1992b). It includes comparisons between time periods of single societies as well as comparisons of parasitism between different, contemporaneous cultures. For example, Fry (1980) compared Fremont and Anasazi parasitism, and also Archaic hunter-gatherer and ancestral Pueblo parasitism. All of these studies fall into the definition of archaeoparasitology.

By contrast, pathoecology is the reconstruction of relationships among behavior, environment, and disease organisms in the development of illness (Martinson et al. 2003; ReinhardandBuikstra2003; Reinhardet al. 2003; Santoro et al. 2003).1his field developed from …

Open And Accessible: The Relationship Between Closures And Circulation In School Library Media Centers, Gail Dickinson, Karen Gavigan, Shana Pribesh

Teaching & Learning Faculty Publications

A hallmark of school library media best practice is for the library media center to be open and accessible to patron use before, during, and after the school day and throughout the entire school year. Anecdotal evidence and informal discussion among school library media specialists indicate that library media facilities are sometimes used for activities unrelated to the mission of the school library media program in the school. These activities may close the library media center to regular patron use for all or part of the school day. This study surveyed school library media specialists in two states and examined …

Schoolyard Improvements And Standardized Test Scores: An Ecological Analysis, Russ Lopez, Richard Campbell, James Jennings

Gastón Institute Publications

Boston MA’s schoolyards had seriously deteriorated since the middle of the 20th century resulting in dangerous and unusable outdoor spaces. Beginning in the mid 1990s, a program to renovate these schoolyards has resulted in approximately half of the schools now having outdoor recreational, learning and garden spaces. This study compared the 4th grade test score results in renovated vs. unrenovated schools. Controlling for school demographics, schools that had a renovated schoolyard had more of their students passed the state mandated math test (1.06, 95% confidence interval = .00012, .12). Effects on the state mandated English language arts test were not …

Correlation Between Boldness And Body Mass In Natural Populations Of The Poeciliid Brachyrhaphis Episcopi, C. Brown, F. Jones, V. Braithwaite

Sentience Collection

The boldness of individual Brachyrhaphis episcopi, collected from regions of high and low predation, was investigated using two independent assays: (1) the time to emerge from cover and (2) the propensity to leave shoal mates and investigate a novel object. A strong correlation between the two assays was revealed such that fish that emerged from shelter sooner were also more likely to approach a novel object. This is indicative of a boldness personality axis acting across both behavioural contexts. Fish from high-predation areas were bolder than those from low-predation areas and males were bolder than females. A significant correlation between …

Animal Minds, Cognitive Ethology, And Ethics, Colin Allen, Marc Bekoff

Sentience Collection

Our goal in this paper is to provide enough of an account of the origins of cognitive ethology and the controversy surrounding it to help ethicists to gauge for themselves how to balance skepticism and credulity about animal minds when communicating with scientists. We believe that ethicists’ arguments would benefit from better understanding of the historical roots of ongoing controversies. It is not appropriate to treat some widely reported results in animal cognition as if their interpretations are a matter of scientific consensus. It is especially important to understand why loose references to ‘‘cognitive ethology’’ by philosophers can signal ignorance …

Functional Assessment Of Problem Behavior In Children With Autism Spectrum Disorders: A Review Of 32 Cases, Jessa R. Love

Masters Theses

The prevalence of autism spectrum disorders among children aged 4 to 17 years is approximately 5.5 to 5.7 out of 1000 children (Centers for Disease Control, 2006). It is not uncommon for children with these disorders to display a wide range of problem behavior (e.g., Farrar-Schneider, 1992; Oswald et al., 1992). While a number of studies have reported aggregated data on the reinforcement functions of such problem behavior, none have reported the distribution of functions with a sample comprised solely of individuals on the autism spectrum. Thus, the purpose of this study was to examine individual client data from an …

Plasticity In Animal Personality Traits: Does Prior Experience Alter The Degree Of Boldness?, Ashley J. Frost, Alexandra Winrow-Giffen, Paul J. Ashley, Lynne U. Sneddon

Ethology Collection

Theoreticians predict that animal ‘personality’ traits may be maladaptive if fixed throughout different contexts, so the present study aimed to test whether these traits are fixed or plastic. Rainbow trout (Onchorhyncus mykiss) were given emboldening or negative experiences in the forms of watching bold or shy individuals responding to novelty or winning or losing fights to examine whether prior experience affected boldness. Bold individuals that lost fights or watched shy demonstrators became more shy by increasing their latency to approach a novel object, whereas shy observers that watched bold demonstrators remained cautious and did not modify their responses to novelty. …

Social Pathogenic Sources Of Poor Community Health, Hayden Smith

Electronic Theses and Dissertations

The United States currently provides a health care system that is neither efficient nor equitable. Despite outspending the world on health care, over three-fourths of developed countries produce better health outcomes (Auerbach et al., 2000). Simultaneously, the "Ecological School of Thought" has documented the large impact that social, economic, and environmental circumstances play in health outcomes. Unfortunately, these 'ecological" studies are frequently conducted without theoretical justification, and rely solely on a cross-sectional research design and a myriad of unrelated variables. This study represents an important step towards the development of a true theory of "ecology". More specifically, we argue that …

Points Of Discussion And Directions For Research On Caddo Historic Archaeology, Timothy K. Perttula

Index of Texas Archaeology: Open Access Gray Literature from the Lone Star State

I start with the premise that there are considerable gaps remaining in our basic knowledge of the Caddo historic archaeological record for the period from ca. 1670-1850 in East Texas. The period between ca. A.D. 1542-1670 is better known archaeologically, thanks in large measure to some significant work at Late Caddo sites along the Red River, along Big Cypress Creek, and in the Neches-Angelina River basins, but there are considerable gaps there as well in what we think we know about the life and times of the Caddo in the 16th and 17th centuries, especially on the role Europeans may …

Grouse Status Survey And Conservation Action Plan, 2006-2010, Ilse Storch, Iucn Species Survival Commission, Grouse Specialist Group, World Pheasant Association

Galliformes Specialist Group and Affiliated Societies: Reports and Other Materials

Executive Summary

Grouse have long attracted and fascinated people. Their display behaviour, and particularly their traditional communal mating grounds or "leks,” have inspired poetry and folklore as well as scientific theories on sexual selection and the evolution of mating systems. In many parts of their range, grouse hunting still plays a major role in the culture, economy, and subsistence of local communities.

The 2006-2010 Grouse Action Plan provides an overview to the distribution, status and threats to all 18 grouse species worldwide and identifies the most immediate conservation needs. It is a product of the joint expertise of the Grouse …

Testing Deterrence Theory With Offenders: Assessing The Effects Of Personal And Vicarious Experience With Punishment And Punishm, Alicia Sitren

Electronic Theses and Dissertations

Stafford and Warr (1993) reconceptualized general and specific deterrence into a single theory in which individuals' propensities to engage in criminal behavior are based on some combination of personal experiences with being punished and avoiding punishment and vicarious (or indirect) experiences with being punished and avoiding punishment. The researchers make a substantial contribution to the deterrence literature by accounting for the effect of punishment avoidance when assessing deterrence theory. Despite the theoretical appeal of this restatement, few studies have tested its empirical merit. The current study tests the applicability of Stafford and Warr's model but also addresses several key limitations …

Farm Animal Welfare: In Legislatures, Corporate Boardrooms, And Private Kitchens, Andrea Gavinelli, Miyun Park

State of the Animals 2007

According to the Food and Agriculture Organization of the United Nations, globally, approximately 56 billion land animals—including nearly 48 billion broiler chickens— are slaughtered for human consumption in a single year (Food and Agriculture Organization of the United Nations 2004), in addition to an untold number of aquatic animals. The numbers of individual animals raised and killed by the meat, egg, and dairy industries far surpass the number of animals with whom human beings have any other relationship—whether they be those seen as fabric, target practice, test tubes, companions, or sideshow spectacles.

Stable Isotopic Niche Predicts Fitness Of Prey In A Wolf–Deer System, C. T. Darimont, P. C. Paquet, T. E. Reimchen

Evolutionary Biology Collection

Interindividual variation in niche presents a potentially central object on which natural selection can act. This may have important evolutionary implications because habitat use governs a suite of selective forces encountered by foragers. In a free‐living native black‐tailed deer, Odocoileus hemionus, population from coastal British Columbia, we used stable isotope analysis to identify individual variation in foraging niche and investigated its relationship to fitness. Using an intragenerational comparison of surviving and nonsurviving O. hemionus over 2 years of predation by wolves, Canis lupus, we detected resource‐specific fitness. Individuals with isotopic signatures that suggested they foraged primarily in cedar ( …

History And Behavioral Ecology During The Middle-Late Transition On The Central California Coast: Findings From The Coon Creek Site (Ca-Slo-9), San Luis Obispo County, Brian F. Codding, Terry L. Jones

Social Sciences

As the focus of intense debate concerning the possible effects of environmental variability on Native populations, the Middle-Late Transition (MLT) is an exceptionally important period in California prehistory. Recent salvage excavations at the Coon Creek Site (CA-SLO-9) on the San Luis Obispo County coast revealed a single, highly discrete component dating cal A.D.900–1300 which is largely synchronous with most definitions of the MLT. With a recovery volume of 23.2 m³, this is the first component to yield artifact and faunal assemblages substantive enough to establish the culture historical markers for this period in this region, and to define …

An Ecological Assessment Of Property And Violent Crime Rates Across A Latino Urban Landscape: The Role Of Social Disorganization And Institutional Anomie Theory, Jeffrey Michael Cancino, Sean P. Varano, Joseph A. Schafer, Roger Enriquez

Justice Studies Faculty Publications

The present research put forth an integrated theoretical framework aimed at providing a more holistic community- level approach explaining crime across a heavily populated Latino city. Guided by social disorganization and institutional anomie theory, this study used several data sources and OLS regression techniques to examine the impact of social disorganization, economic and noneconomic institutional characteristics on rates of property and violent crime across 1,016 census block groups in San Antonio, Texas. While several findings emerged, interactions between alcohol density and concentrated disadvantage were significant and positively associated with property and violent crime. Interactions between welfare generosity and concentrated disadvantage …

Th Politics Of Hate: Ultranationalist And Fundamentalist Tactics And Goals, Joan Davison

Faculty Publications

Ultranationalist and religious fundamentalist movements frequently use hate to mobilize people. These groups possess a sophisticated understanding of the importance of appealing to the emotions. Leaders often employ xenophobic language intended to inspire fear and justify a defensive reaction. The movements also rely heavily upon symbols, myths, and public events to simplify and communicate the "truths" of their ideologies. The leaders convey messages with tremendous affective appeal. Yet, measures exist to counter and contain the politics of hate. The development of civil society, group rights, a free media, and integrated institutions can contribute to a durable solution in cases of …

Social Organization And Determinants Of Spatial Distribution Of Khur (Equus Hemionus Khur), Nita Shah, Qamar Qureshi

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

Khur (Equus hemionus khur) is an endangered species for the most part restricted in little Rann of Kutch (India) and surrounding areas. We investigated factors influencing spatial distribution and social organization of khur. The spatial distribution is largely influenced by distribution of food patches and water in this ecosystem. The inter group distances were smaller in resource rich areas in comparison to resource poor areas (p = 0.017). The group sizes are larger in areas having higher productivity (r = 0.85) and rainfall (r = 0.88). Four social units are observed in khur (a) Family …
