Intellectual Property - Copyright, Peggy Hoon Apr 2000

Intellectual Property - Copyright, Peggy Hoon

Ethics in Science and Engineering National Clearinghouse

The goal of this module is to present the major issues surrounding intellectual property (IP): rather than attempt to discuss all four types of IP, trademarks, trade secrets, patents and copyright, we will focus on copyright. Our Faculty Expert for this module is Peggy Hoon, Director of the Scholarly Communications Center, NC State University. The Overview section presents two chapters from two well known textbooks on research ethics. In the Applied Ethics portion we discuss the idea of the labor contract and the idea of the Intellectual Commons to clarify some of the more complex issues. In the Central Theme …


Responsible Use Of Statistical Methods, Larry Nelson, Charles Proctor, Cavell Brownie Apr 2000

Responsible Use Of Statistical Methods, Larry Nelson, Charles Proctor, Cavell Brownie

Ethics in Science and Engineering National Clearinghouse

Responsible Use of Statistical Methods focuses on good statistical practices. In the Introduction we distinguish between two types of activities; one, those involving the study design and protocol (a priori) and two, those actions taken with the results (post hoc.) We note that right practice is right ethics, the distinction between a mistake and misconduct and emphasize the importance of how the central hypothesis is stated. The Central Essay, Identification of Outliers in a Set of Precision Agriculture Experimental Data by Larry A. Nelson, Charles H. Proctor and Cavell Brownie, is a good paper to study. The Applied Ethics section …


Science And The Media: Ethics Issues, Joann Burkholder Apr 2000

Science And The Media: Ethics Issues, Joann Burkholder

Ethics in Science and Engineering National Clearinghouse

This module addresses the complex interface of research and the media; this interface necessarily involves issues of public policy, however, for the purposes of this module we will focus on media issues and touch on public policy in the Thinking Outside the Box section. For simplicity, when we refer to “media” we are speaking of journalists covering the science beat. In the Introduction we talk about the special collaboration between the media and the researcher and the challenges both face in communicating science to the public at large. We note the ethical component inherent in all communication and include quotations …


Taking Animal Welfare Seriously: Minimizing Pain And Distress In Research Animals, The Humane Society Of The United States Apr 2000

Taking Animal Welfare Seriously: Minimizing Pain And Distress In Research Animals, The Humane Society Of The United States

ANIMAL RESEARCH

Pain and distress caused by specific research models and techniques raise serious concerns for those in the animal welfare community as well as in the scientific community. Yet good estimates of how much animal pain and/or animal distress is caused by particular techniques or methods are not yet available. The HSUS has compiled a preliminary list of research models and techniques that cause pain and distress. Analyses by the USDA and HSUS indicate that the majority of the animals reported in Column E are used in various testing procedures, with vaccine testing prominent among them. More data are needed to …

How Do We Know There Is A Population-Environment Problem?, Peter J. Taylor Mar 2000

How Do We Know There Is A Population-Environment Problem?, Peter J. Taylor

Working Papers on Science in a Changing World

Five fictional friends of the author have agreed to meet and talk, hoping that he was right when he claimed that discussion crossing the usual boundaries of their fields would enrich their different inquiries and concerns. Ecolo, a natural and human ecologist, breaks the ice. He wants to marshall scientific knowledge to persuade others of the seriousness of the population problem. He is questioned by Philoso, whose philosophical bent leads her to observe the models that people use and to ask how they support the claims they make. In turn, the other three join in: Activo, an activist who is …


Bubble Ring Play Of Bottlenose Dolphins (Tursiops Truncatus): Implications For Cognition, Brenda Mccowan, Lori Marino, Erik Vance, Leah Walke, Diana Reiss Mar 2000

Bubble Ring Play Of Bottlenose Dolphins (Tursiops Truncatus): Implications For Cognition, Brenda Mccowan, Lori Marino, Erik Vance, Leah Walke, Diana Reiss

Sentience Collection

Research on the cognitive capacities of dolphins and other cetaceans (whales and porpoises) has importance for the study of comparative cognition, particularly with other large-brained social mammals, such as primates. One of the areas in which cetaceans can be compared with primates is that of object manipulation and physical causality, for which there is an abundant body of literature in primates. The authors supplemented qualitative observations with statistical methods to examine playful bouts of underwater bubble ring production and manipulation in 4 juvenile male captive bottlenose dolphins (Tursiops truncatus). The results are consistent with the hypothesis that dolphins monitor the …


Agonistic Behaviour And Biogenic Amines In Shore Crabs Carcinus Maenas, Lynne U. Sneddon, Alan C. Taylor, Felicity A. Huntingford, David G. Watson Feb 2000

Agonistic Behaviour And Biogenic Amines In Shore Crabs Carcinus Maenas, Lynne U. Sneddon, Alan C. Taylor, Felicity A. Huntingford, David G. Watson

Sentience Collection

To investigate the role of certain neurohormones in agonistic behaviour, fights were staged between pairs of size-matched male shore crabs Carcinus maenas, and blood samples were taken immediately after the contests had been resolved. Samples were also taken from these crabs at rest (before and after fighting) and after walking on a treadmill. A control group of crabs also had samples taken on each experimental day. Concentrations of tyramine, dopamine, octopamine, serotonin (5-HT) and norepinephrine were determined in each blood sample using a gas chromatography/mass spectrometry (GC-MS) system. Norepinephrine was not detectable in any of the samples, but the standards …


Stocking Rate Guidelines For Rural Small Holdings, Swan Coastal Plain And Darling Scarp And Surrounds, Western Australia, Dennis Van Gool, Ken Angell, Lindsay Stephens Feb 2000

Stocking Rate Guidelines For Rural Small Holdings, Swan Coastal Plain And Darling Scarp And Surrounds, Western Australia, Dennis Van Gool, Ken Angell, Lindsay Stephens

Agriculture reports

Small rural holdings are often owned by people who want to pursue a semi-rural lifestyle but who are inexperienced in land management issues. This can result in landholders stocking their properties with animals at rates higher than the land resources can sustain, leading to degradation problems such as soil erosion, water pollution and damage to vegetation. This document provides information and guidelines to help planners, developers, local authorities and land owners determine the base stocking rates for rural small holdings on the Swan Coastal Plain and Darling Scarp and immediate surrounds. The advice utilises Agriculture Western Australia’s rural stocking rate …


Ontogenetic Shifts In The Costs Of Living In Groups: Focal Observations Of A Pholcid Spider (Holocnemus Pluchei), Elizabeth Jakob, Julie Blanchong, Mary Popson, Kristine Sedey, Michael Summerfield Jan 2000

Ontogenetic Shifts In The Costs Of Living In Groups: Focal Observations Of A Pholcid Spider (Holocnemus Pluchei), Elizabeth Jakob, Julie Blanchong, Mary Popson, Kristine Sedey, Michael Summerfield

Psychological and Brain Sciences Faculty Publication Series

Holocnemus pluchei spiders (Family Pholcidae) facultatively live in groups: sometimes they live alone and sometimes they share webs. In the field groups vary in size and composition and include spiders of all ages and either sex. Group membership is flexible and individuals move frequently among groups. To understand group formation and maintenance it is necessary to understand the costs of group membership. We used focal animal sampling to investigate the cost of group living for spiders of different ages across a range of group sizes. Both spider age and group size affected the costs incurred by group-living spiders. There was …


Oxidative Stress Resistance: A Robust Correlated Response To Selection In Extended Longevity Lines Of Drosophila Melanogaster?, Lawrence G. Harshman, Beth A. Haberer Jan 2000

Oxidative Stress Resistance: A Robust Correlated Response To Selection In Extended Longevity Lines Of Drosophila Melanogaster?, Lawrence G. Harshman, Beth A. Haberer

Lawrence G. Harshman Publications

Stress resistance is associated with longevity in Drosophila melanogaster and other model organisms used for genetic research. The present study tests for oxidative stress resistance in one set of lines selected for late-life reproduction and extended longevity. Both females and males from the selected lines were appreciably more resistant to oxidative stress than were flies from the control lines. A relative increase in oxidative stress resistance is a correlated response to selection in this laboratory selection experiment. Increased oxidative stress resistance appears to be a relatively robust correlated response to laboratory selection for late-life reproduction and extended longevity.


The Space Of Jumping Emerging Patterns And Its Incremental Maintenance, Jinyan Li, Kotagiri Ramamohanarao, Guozhu Dong Jan 2000

The Space Of Jumping Emerging Patterns And Its Incremental Maintenance, Jinyan Li, Kotagiri Ramamohanarao, Guozhu Dong

Kno.e.sis Publications

The concept of jumping emerging patterns (JEPs) has been proposed to describe those discriminating features which only occur in the positive training instances but do not occur in the negative class at all; JEPs have been used to construct classifiers which generally provide better accuracy than the state-of-the-art classifiers such as C4.5. The algorithms for maintaining the space of jumping emerging patterns (JEP space) are presented in this paper. We prove that JEP spaces satisfy the property of convexity. Therefore JEP spaces can be concisely represented by two bounds: consisting respectively of the most general elements and the most specific …


Regulation Of Contact With Offspring By Domestic Sows: Temporal Patterns And Individual Variation, E. A. Pajor, D. L. Kramer, D. Fraser Jan 2000

Regulation Of Contact With Offspring By Domestic Sows: Temporal Patterns And Individual Variation, E. A. Pajor, D. L. Kramer, D. Fraser

Rearing Behavior Collection

We used a sow-controlled housing system to examine temporal and individual variation in the tendency of sows to associate with young. During a 5-week lactation, 22 sows and litters were housed in a pen where the sow could freely leave and re-enter the piglets' area by stepping over a barrier that the piglets could not cross. Despite this option, the sows remained with the piglets almost constantly during the 1st day after birth. Nineteen sows ('leavers') changed to spending most of their time away from the litter at some point in the lactation. The change was rapid, often within a …


The Relationship Of Animal Protection Interests To Animal Damage Management: Historic Paths, Contemporary Concerns And The Uncertain Future, John Hadidian Jan 2000

The Relationship Of Animal Protection Interests To Animal Damage Management: Historic Paths, Contemporary Concerns And The Uncertain Future, John Hadidian

Conservation Biology and Animal Welfare Collection

More than a decade ago Schmidt (1989) called for consideration of animal welfare to become a "firstorder" decision rule in wildlife management concerns, including animal damage control. Although there has been movement in that direction, this clearly has not yet come to pass. This paper takes a brief look at the interests we call animal damage management, animal welfare and protection, animal rights, and environmentalism in order to speculate about their shared concerns and the uncertain future before them. Since animal damage and the management of that damage cannot be abstracted from the environmental context in which they occur, this …


Lack Of Reproduction In Muskoxen And Arctic Hares Caused By Early Winter?, L. David Mech Jan 2000

Lack Of Reproduction In Muskoxen And Arctic Hares Caused By Early Winter?, L. David Mech

USGS Northern Prairie Wildlife Research Center

A lack of young muskoxen (Ovibos moschatus) and arctic hares (Lepus arcticus) in the Eureka area of Ellesmere Island, Northwest Territories (now Nunavut), Canada, was observed during summer 1998, in contrast to most other years since 1986. Evidence of malnourished muskoxen was also found. Early winter weather and a consequent 50% reduction of the 1997 summer replenishment period appeared to be the most likely cause, giving rise to a new hypothesis about conditions that might cause adverse demographic effects in arctic herbivores.

Durant l’été 1998, et ce, à la différence de la plupart des années depuis …


Do Wolves Affect White-Tailed Buck Harvest In Northeastern Minnesota?, L. David Mech, Michael E. Nelson Jan 2000

Do Wolves Affect White-Tailed Buck Harvest In Northeastern Minnesota?, L. David Mech, Michael E. Nelson

USGS Northern Prairie Wildlife Research Center

We used simple linear regression to analyze 8-23 years of data on a wolf (Canis lupus) population and human harvest of white-tailed deer (Odocoileus virginianus) bucks in northeastern Minnesota to determine any effects of wolves on buck harvesting. Over the long term, wolves accounted for at least 14-22% inter-year variation in buck harvest in the region, but an unknown amount of variation in hunter effort have obscured any more precise estimate. For part of the area with poorest habitat, we found strong relationships (r2 = 0.66-0.84) between annual wolf numbers and buck harvests from 1988 …


Proximity Of White-Tailed Deer, Odocoileus Virginianus, Ranges To Wolf, Canis Lupus, Pack Homesites, Michael E. Nelson, L. David Mech Jan 2000

Proximity Of White-Tailed Deer, Odocoileus Virginianus, Ranges To Wolf, Canis Lupus, Pack Homesites, Michael E. Nelson, L. David Mech

USGS Northern Prairie Wildlife Research Center

Seven adult female White-tailed Deer (Odocoileus virginianus) in northeastern Minnesota lived within 1.8 km of Wolf pack (Canis lupus) homesites without vacating their home ranges. Six of these deer and at least three of their fawns survived through the Wolf homesite period.


Prolonged Winter Undernutrition And The Interpretation Of Urinary Allantoin:Creatinine Ratios In White-Tailed Deer, Glenn D. Delgiudice, Ken D. Kerr, L. David Mech, Ulysses S. Seal Jan 2000

Prolonged Winter Undernutrition And The Interpretation Of Urinary Allantoin:Creatinine Ratios In White-Tailed Deer, Glenn D. Delgiudice, Ken D. Kerr, L. David Mech, Ulysses S. Seal

USGS Northern Prairie Wildlife Research Center

The urinary allantoin:creatinine (A:C) ratio (expressed in micromoles of allantoin to micromoles of creatinine) has shown potential as an index of recent winter energy intake in preliminary controlled studies of elk (Cervus elaphus) involving mild condition deterioration (up to 11% loss of body mass). To ensure reliable nutritional assessments of free-ranging cervids by measuring A:C ratios of urine in snow, it is essential to extend this work. We assessed the effect of moderate and severe winter nutritional restriction on urinary A:C ratios of captive white-tailed deer (Odocoileus virginianus) that lost up to 32% body mass and …


Accuracy And Precision Of Estimating Age Of Gray Wolves By Tooth Wear, Philip S. Gipson, Warren B. Ballard, Ronald M. Nowak, L. David Mech Jan 2000

Accuracy And Precision Of Estimating Age Of Gray Wolves By Tooth Wear, Philip S. Gipson, Warren B. Ballard, Ronald M. Nowak, L. David Mech

USGS Northern Prairie Wildlife Research Center

We evaluated the accuracy and precision of tooth wear for aging gray wolves (Canis lupus) from Alaska, Minnesota, and Ontario based on 47 known-age or known-minimum-age skuIIs. Estimates of age using tooth wear and a commercial cementum annuli-aging service were useful for wolves up to 14 years old. The precision of estimates from cementum annuli was greater than estimates from tooth wear, but tooth wear estimates are more applicable in the field. We tended to overestimate age by 1-2 years and occasionaIIy by 3 or 4 years. The commercial service aged young wolves with cementum annuli to within …

The Decline Of Ethics Or The Failure Of Self-Regulation? The Case Of Alcohol Advertising, Sandra C. Jones Jan 2000

The Decline Of Ethics Or The Failure Of Self-Regulation? The Case Of Alcohol Advertising, Sandra C. Jones

Faculty of Health and Behavioural Sciences - Papers (Archive)

Restrictions on alcohol advertising have increasingly become an issue for debate around the world. Some countries rely on governmental regulation; whereas others, including Australia, utilise a system of industry selfregulation. This study calls into question the effectiveness of the alcohol beverage industry’s self-regulation of advertising. Between May 1998 and April 1999, 11 alcohol advertising complaints (relating to nine separate advertisements) were lodged with the Advertising Standards Board (ASB) by members of the general public. In the present study, five expert judges were selected to review these complaints, without knowing the ASB’s rulings, and to judge whether the advertisement(s) breached any …


Evaluation Of The Helping Hands Volunteer Program For People With Mental Illness, Judy A. Pickard, Frank P. Deane Jan 2000

Evaluation Of The Helping Hands Volunteer Program For People With Mental Illness, Judy A. Pickard, Frank P. Deane

Faculty of Health and Behavioural Sciences - Papers (Archive)

Volunteer programs have been used to alter attitudes, provide long-term knowledge towards mental illness and increase the quality of life of consumers receiving volunteer services. Sixteen volunteers completed an 18-hour training program and in pairs worked with 11 consumers over 4 months. Sixteen volunteers completed training measures of knowledge and attitudes scales. Pre and post program quality of life and behavioural functioning measures were taken on 5 consumers. Volunteers maintained their knowledge of mental illness over 6 months and had significant increases in their comfort in interactions with people who have mental illness. Case managers, consumers and volunteers all reported …


Thermoregulation By Kangaroos From Mesic And Arid Habitats: Influence Of Temperature On Routes Of Heat Loss In Eastern Grey Kangaroos (Macropus Giganteus) And Red Kangaroos (Macropus Rufus), Terence J. Dawson, Cyntina E. Blaney, Adam J. Munn, Andrew Krockenberger, Shane K. Maloney Jan 2000

Thermoregulation By Kangaroos From Mesic And Arid Habitats: Influence Of Temperature On Routes Of Heat Loss In Eastern Grey Kangaroos (Macropus Giganteus) And Red Kangaroos (Macropus Rufus), Terence J. Dawson, Cyntina E. Blaney, Adam J. Munn, Andrew Krockenberger, Shane K. Maloney

Faculty of Science - Papers (Archive)

We examined thermoregulation in red kangaroos (Macropus rufus) from deserts and in eastern grey kangaroos (Macropus giganteus) from mesic forests/woodlands. Desert kangaroos have complex evaporative heat loss mechanisms, but the relative importance of these mechanisms is unclear. Little is known of the abilities of grey kangaroos. Our detailed study of these kangaroos' thermoregulatory responses at air temperatures (T-a) From -5 degrees to 45 degrees C showed that, while some differences occur, their abilities are fundamentally similar. Both species show the basic marsupial characteristics of relatively low basal metabolism and body temperature (T-b). Within the thermoneutral zone, T-b was 36.3 degrees …


Enhanced Tumor Growth In Uv-Irradiated Skin Is Associated With An Influx Of Inflammatory Cells Into The Epidermis, Ronald Sluyter, Gary M. Halliday Jan 2000

Enhanced Tumor Growth In Uv-Irradiated Skin Is Associated With An Influx Of Inflammatory Cells Into The Epidermis, Ronald Sluyter, Gary M. Halliday

Faculty of Science - Papers (Archive)

UV radiation causes a number of cellular changes within the skin which play a role in tumor outgrowth, including immunosuppression and production of growth-enhancing cytokines, Both of these enable tumors to grow but their relative importance in carcinogenesis is poorly defined. In this study, C3H/HeN mice were exposed to a single inflammatory dose of 410 mJ/cm(2) UVB radiation (plus 100 mJ/cm2 UVA radiation) followed by the inoculation of a regressor squamous cell carcinoma into or the painting of oxazolone onto the treated skin. Tumors transplanted 2 or 3 but not 4 days after irradiation had a significantly higher growth rate …


Use Of Self-Report To Monitor Overweight And Obesity In Populations: Some Issues For Consideration, Victoria M. Flood, Karen Webb, Ross Lazarus, Glen Pang Jan 2000

Use Of Self-Report To Monitor Overweight And Obesity In Populations: Some Issues For Consideration, Victoria M. Flood, Karen Webb, Ross Lazarus, Glen Pang

Faculty of Health and Behavioural Sciences - Papers (Archive)

Objective: To examine the validity of self reported height and weight data reported over the telephone in the 1997 NSW Health Survey, and to determine its accuracy to monitor overweight and obesity in population surveys. Method: Self-reported and measured heights and weights were collected from 227 people living in Western Sydney, who had participated in the NSW Health Survey 1997. Results: Self-reported (SR) weights and heights led to misclassification of relative weight status. BMI, based on measured weights and heights, classified 62% of males and 47% of females as overweight or obese, compared with 39% and 32%, respectively, from self-report. …

Recent Progress In Psychiatric Genetics—Some Hope But No Hype, Scott F. Stoltenberg, Margit Burmeister Jan 2000

Recent Progress In Psychiatric Genetics—Some Hope But No Hype, Scott F. Stoltenberg, Margit Burmeister

Department of Psychology: Faculty Publications

The reputation of the field of psychiatric genetics has recently become tarnished in the view of many human geneticists. Too many linked loci were claimed and withdrawn, too many association studies published and not confirmed, and, more recently, too many new and different chromosomal regions have been implicated for the same disorder. Here, we summarize recent trends, focusing on research that moves away from traditional linkage studies. Some promising strategies include psychopharmacogenetics and consideration of endophenotypes such as neurophysiological and behavioral markers in addition to the clinical diagnosis. Utilization of rapid and automated methods for scoring genetic variants in large-scale …


Dutch John Excavations: Seasonal Occupations On The North Slope Of The Uintah Mountains., U.S. Forest Service Jan 2000

Dutch John Excavations: Seasonal Occupations On The North Slope Of The Uintah Mountains., U.S. Forest Service

All U.S. Government Documents (Utah Regional Depository)

From 1993-1995 Forest Service crews conducted an intensive archaeological inventory of the Dutch John Area, Daggett County, Utah. Seventy seven archaeological sites were identified within the exchange boundary. Thirty three sites were determined to be eligible for the National Register of Historic Places. Between April 1995 and September 1998 testing and excavation of the significant sites proceeded as outlined in the Dutch John Mitigation Plan. This volume reports the results of those excavations.


A Record Large Wolf, Canis Lupus, Pack In Minnesota, L. David Mech Jan 2000

A Record Large Wolf, Canis Lupus, Pack In Minnesota, L. David Mech

USGS Northern Prairie Wildlife Research Center

This report documents a pack of 22-23 Wolves (Canis lupus) in central Minnesota. This is larger than the largest pack previously observed on the mainland in the midwestern U.s. during 650 wolf pack-years. Because this record-large pack preyed on White-tailed Deer (Odocoileus virginianus), one of the Wolfs smaller prey, it is evidence that pack size and prey size are not tightly related. It also indicates the size that Wolf packs can attain in the area if fully protected from human persecution.
