Assessing Measurement Techniques For Identifying Race, Ethnicity, And Gender: Observation-Based Data Collection In Airports And At Immigration Checkpoints, Steven K. Smith, Carol J. Defrances

United States Department of Justice: Publications

Over the past several years State and local governments have engaged in data collection regarding demographic characteristics of persons stopped by the police. These efforts are aimed at understanding factors used by law enforcement to make such stops. While data collections on law enforcement encounters have been undertaken, analysts have debated the availability of methods to meaningfully analyze these data. One complicating factor is the need to identify the baseline data necessary to make assessments regarding different racial groups’ experience with the police.

In 1999 several Federal law enforcement agencies designed and implemented data collection procedures to capture race and …

Food Pulses Increase Longevity And Induce Cyclical Egg Production In Mediterranean Fruit Flies, James R. Carey, Pablo Liedo, Lawrence G. Harshman, X. Liu, Hans-Georg Müller, Linda Partridge, Jane-Ling Wang

Lawrence G. Harshman Publications

1. Inasmuch as virtually all studies on mortality and reproduction in insects are conducted under conditions in which food availability is constant, little is known about the demographic response of insects to variable food environments. For example, it is not known if and to what extent the life expectancy of insects subjected to shortages of high-quality food will increase and/or whether this increase is associated with major decreases in lifetime reproduction.

2. Therefore cohorts of 100 individual female medflies were subjected to different sets of conditions of protein availability (interspersed with sugar-only diets) including ad libitum sugar-only (no protein), ad …

Paternity Efficiency In Turkeys Differes Extensively After Hererospermic Insemination, Ann M. Donoghue, Murray R. Bakst, Paul Drummond, Shakura Haqque, Edward J. Smith, Daniel J. Donoghue

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

All commercial turkey hens in the U.S. are bred by artificial insemination (AI).  Since semen samples are pooled from 10 or more males (heterospermic inseminations), paternity of the progeny is rarely known.  Whereas it is known that sperm competition exists, the degree to which any male's sperm fertilizes ova relative to other male's remains unknown.  In this work, we determined individual male fecundity relative to that of other males in the study and attempted to establish a relationship between male fecundity and semen characteristics in turkeys.  Fingerprinting of genomic DNA from parents and offspring was used to determine parentage efficiency. …

Professors As Clients For Instructional Development, Ronald A. Smith, George L. Geis

To Improve the Academy: A Journal of Educational Development

Although there is a large amount of activity and a sizeable literature in the area of instructional development, there has been relatively little research on faculty members, the clientele for improvement efforts. This paper highlights some characteristics of professors that are relevant to improvement activities. Professors are interested in, value, and work on their teaching; they think they teach rather well. However, they demonstrate a lack of sophistication in talking about teaching and the development of instruction. They focus primarily upon content rather than design or methodology. Teachers' views of what should be done to enhance instruction are discussed and …

Social Networks And Daily Activities Of Street Youth In Belo Horizonte, Brazil, Regina Campos, Marcela Raffaelli, Walter Ude, Marilia Greco, Andrea Ruff, Jon Rolf, Carlos Mauricio Antunes, Neal Halsey, Dirceu Greco, Mauro Jeronymo, Carl Kendall, Alice Payne Merritt, Jorge Andrade Pinto, Eliana Siqueira, Barbara De Zalduondo

Department of Psychology: Faculty Publications

Social networks and daily activities of children and adolescents living and/or working on the streets of a large Brazilian city were examined. Drawing on data collected through structured surveys, in-depth interviews, focus group discussions, and field observations, we described street youths’ family situation, social resources, institutional experiences, survival activities, and problem behaviors and investigated differences attributable to age, gender, and living situation (at home or on the street). Youngsters who lived at home and worked on the street appeared to be experiencing orderly development despite their impoverished circumstances. Youngsters who lived on the street showed hallmarks of psychological and physical …

A Metapopulation Approach To Pitcher's Thistle (Cirsium Pitcheri) Recovery In Southern Lake Michigan Dunes, A. Kathryn Mceachern, Marlin L. Bowles, Noel B. Pavlovic

United States Geological Survey: Staff Publications

Successful recovery planning for a rare species relies upon knowledge of its life history and ecology, as well as an understanding of its habitat requirements and disturbance regime (Gilpin & Soule 1986, Lande 1988a). Species that depend upon early-successional or transient habitats in landscape mosaics present unique recovery challenges (Menges 1990). They require perpetuation of multiple populations within a shifting mosaic of local habitats. Recovery plans for these species must be formulated from an understanding of population demography within the context of community and landscape dynamics. Processes that maintain landscape mosaics must be given long-term protection if recovery is to …

Impacts Of Biological Invasions On The Management And Recovery Of Rare Plants In Haleakala National Park, Maui, Hawaiian Islands, Lloyd Loope, Arthur Medeiros

United States National Park Service: Publications

Biological invasions assisted by humans are impoverishing biological diversity worldwide (MacDonald et al. 1989, Diamond 1989). Such invasions are particularly devestating to the biota of oceanic islands such as Hawaii (Williamson 1981, Brockie et al. 1988, Hawaii Department of Land and Natural Resources et al. 1991). Ecosystems of the Hawaiian Islands are much more vulnerable to biological invasions than are continental ecosystems, because the organisms in them have evolved in isolation from many of the forces that have shaped continental organisms, including foraging and trampling by herbivorous mammals, predation by ants and mammals, virulent diseases, and fires (Loope & Mueller-Dombois …

Disenrollment Patterns Of Elderly In Managed Care And Fee For Service, Kenneth G. Manton, Dennis H. Tolley, Robert Newcomer, James C. Vertrees, Charlene Harrington

Journal of Actuarial Practice (1993–2006)

As the trend to provide health care through managed care facilities increases, the need to examine ,vhy insured individuals voluntarily terminate managed care coverage grows. Voluntary termination of coverage, or dis enrollment, has both social and fiscal implications. Particularly among the elderly, patterns of disenrollment likely are related to self assessment of care needs and levels of health. In this paper we examine the patterns of dis enrollment among elderly enrollees as a function of health status and disability. We focus on disenrollment patterns from an experimental prepaid extended care facility, called a social HMO (S/HMO) and compare this pattern …

Survivorship And Recruitment In A Long-Lived Prairie Perennial, Ipomoea Leptophylla (Convolvulaceae), Kathleen H. Keeler

School of Biological Sciences: Faculty Publications

Little is known of the lifespans of herbaceous plants, especially in grasslands, although this information is basic to understanding the dynamics of species and ecosystems. Permanently marked plants of the bush morning glory, Ipomoea leptophylla (Convolvulaceae), in Nebraska sandhills prairie were censused annually from 1979-1989. While the average annual death rate was 2.6 per 100, virtually all the mortality was among smaller and probably younger plants. Recruitment varied greatly among years. Of plants of known age, the median age at first flowering was 6 yr. After 9 yr 30% had never flowered. Larger size classes flowered more frequently than smaller …

A Mimbres Burial With Associated Colon Remains From The Nan Ranch Ruin, New Mexico, Harry J. Shafer, Marrianne Marek, Karl J. Reinhard

Karl Reinhard Publications

The skeletal remains of an adult male associated with desiccated tissue and a coprolite were recovered from an apen-air midden deposit at the NAN Ranch Ruin (LA15049)) a large Mimbres site in Grant County) New Mexico. The find dates to about A.C. 1000-1100. Identifiable macroscopic elements in the caprolite consist offi nely fragmented corn and tiny seed fragments of an unknown plant. High amounts of willow (Salix) and mustard (Brassicaceae) pollen may indicate the ingestion of medicinal plants to combat a deteriorating health condition. The individual was approximately 35 -40 years old at the time of death and suffered from …

Evaluation Of Inter-Flock Genetic Improvement Programs For Sheep And Goats, G. B. Nicoll, L. Bodin, J. V. Jonmundson

World Congress on Genetics Applied to Livestock Production: 3rd (1986)

Some of the factors involved in inter-flock or breed improvement programs are discussed. Such programs are complicated by the fact that sheep and goats produce a wide range of products under diverse environmental, management and economic circumstances. This leads to problems in defining realistic breeding objectives arising from determining the beneficiaries of genetic improvement, the major genetic decision makers in the industry and the relative importance of the various productive characteristics. The implementation of functional performance recording systems, breeding systems to generate young sire replacements, and testing systems to disseminate genetic improvement, also depend on the conditions under which the …

Relationship Between Seasonal Changes In Forage Quality And Feeding Patterns In Meadow Voles (Microtus Pennsylvanicus), Ronald J. Brooks, Stephen A. Struger

Eastern Wildlife Damage Control Conference: 2nd (1985)

Forage analyses revealed that mowed orchards provide a relatively high quality forage to meadow voles (Microtus pennsylvanicus), especially in the fall. Mowed forage was characterized by significantly higher protein and moisture content and significantly lower acid and neutral detergent fibre and lignin than forage from an abandoned orchard. Energy and fat were not significantly affected by mowing.. However, vole numbers declined markedly in mowed regions in comparison to undisturbed areas. Voles preferred to inhabit areas with dense cover even though vegetative dieback had occurred. Voles did not exhibit any distinct preference for either cracked corn (rodenticide carrier agent) …

Women On The Great Plains Recent Developments Research, Glenda Riley

Great Plains Quarterly (through 2013)

During the past dozen years or so, scholars have become increasingly involved in researching the lives and experiences of women on the Great Plains. At the same time, interest in learning more about the lives of all types of western, frontier, farm, and rural women has burgeoned. As a result, researchers now devote their careers to these topics, national conferences convene to disseminate and refine this increasing scholarship, and journals commit theme issues to presenting research results.

This essay is a survey of research developments concerning plainswomen between the early 1970s and the present day. The purpose of such an …

Regionalism And The Great Plains: Problems Of Concept And Method, Frederick C. Luebke

Department of History: Faculty Publications

American scholars have used the concept of regionalism to organize their thinking about certain aspects of national experience for many decades. Its meaning is imprecise because it has had to serve a broad spectrum of purposes. Inevitably regionalism means different things to different people; its content will vary with the purposes and standards of those using the concept. In literature, for example, a debate has been going on for a century over the merits of regionalism versus other theories ofliterary creation. Its intensity has waxed and waned with the times, but in our century regionalism in literature has achieved its …

Reproduction In A Nebraska Sandhills Population Of The Northern Prairie Lizard Sceloporus Undulatus Garmani, Royce E. Ballinger, Dale L. Droge, Steven M. Jones

Papers in Herpetology

The reproductive cycle of Sceloporus undulatus was studied in western Nebraska. Females mature in the 1st year following hatching at a size of 45 mm SVL. Two clutches averaging 5.5 eggs each are produced. Egg sizes are similar to other grassland populations and contain approximately 650 g-cal. per egg. Egg weight to body weight ratios of 0.33 were the highest which have been reported for any S. undulatus population. Variation in life history characteristics within and between grassland and eastern woodland habitat types are explicable given a knowledge of the growing season, predation intensity and demographic environment.

Human And Cultural Ecology: A Partial Bibliography, Michael C. Gunn

Nebraska Anthropologist

The following bibliography represents a partial listing of books and articles dealing with human and cultural ecology. Central to this bibliography are titles dealing with the conceptual and methodological aspects of human/cultural ecology as applicable to the broad field of anthropology. Also of primary importance are titles dealing with the anthropological use of population demography. Topics of related interest (general ecology, human adaption, bioenergetics, etc.) are represented by selected titles. While the bibliography falls far short of total citation of all articles dealing with the aforementioned topics, it should provide a firm base upon which the student or researcher may …

“Sociology At Nebraska: 1884-1929,” Together With “A History Of Sociology At The University Of Nebraska,” By J.O. Hertzler, Joyce O. Hertzler, Mary Jo Deegan

Department of Sociology: Faculty Publications

At the turn of the century the University of Nebraska was one of the four leading centers of sociology in the United States. Despite this auspicious start, Nebraska has remained relatively obscure in the accounts of the history of Sociology. This is partially a result of its size: until 1959 the faculty consisted of only five members and was oriented to a small but quality graduate program. The document which follows is an original manuscript recording the early history of the department. It was written by Joyce O. Hertzler in the Winter of 1929. This rough draft, now yellowing and …

The Learning Environment For Aggression And Anti-Social Behavior Among The !Kung, Patricia Draper

Department of Anthropology: Faculty Publications

The !Kung are a provocative case study: a controversy exists as to whether they are harmless or, in fact, murderous. In addition, since the !Kung are by now well studied, one can use specific information about !Kung behavior to examine general propositions about social control and interpersonal conflict in hunting and gathering societies generally.

This paper will address the question of interpersonal conflict and aggression among !Kung, with particular emphasis on the learning environment of children and how it relates to the learning of aggressive behavior. Of concern here will be parental attitudes toward children’s behavior and techniques for dealing …

"Introduction" To The Great Plains: Environment And Culture, Frederick C. Luebke

Department of History: Faculty Publications

In the pages that follow I have summarized the views of certain selected scholars whose emphases seem to illustrate changing and contrasting interpretations of the interaction of environment and culture on the Great Plains. I have grouped their writings into two inclusive categories. First come those whose conceptual schemes suggest the primacy of environmental variables. I refer to these scholars, perhaps simplistically, as environmentalists, even though this term has acquired a different meaning in recent years. In the second group are several scholars, selected more arbitrarily than the first, whose writings seem to accord more importance to cultural factors. For …

Cultural Pressure On Sex Differences, Patricia Draper

Department of Anthropology: Faculty Publications

This paper suggests that sex differences in the behavior of children exist but are not necessarily intensified under certain cultural conditions. Under conditions of culture change to a sedentary economy, certain elements of male and female differentiated behavior are exploited in the process of increasing sex differentiation.
