On Nancy Ordover's American Eugenics: Race, Queer Anatomy, And The Science Of Nationalism, Markus Rheindorf Oct 2003

On Nancy Ordover's American Eugenics: Race, Queer Anatomy, And The Science Of Nationalism, Markus Rheindorf

Reconstruction: Studies in Contemporary Culture

[First paragraph]

Nancy Ordover's American Eugenics is a very personal book, not so much in terms of its content, but because of the convictions and a deep-felt sense of injustice that have inspired it. And while the author is straightforward in acknowledging her personal motivations, this is not to suggest that American Eugenics ever lapses into personal anecdote or polemic; far from it, the book is a serious and tightly argued attempt to grasp, in Ordover's words the resiliency of this often discredited but never dormant philosophy (xvi). In order to do this, Ordover goes on to argue in her …

The Evidence For Pain In Fish: The Use Of Morphine As An Analgesic, Lynne U. Sneddon Sep 2003

The Evidence For Pain In Fish: The Use Of Morphine As An Analgesic, Lynne U. Sneddon

Veterinary Science and Medicine Collection

This paper discusses the evidence for pain perception in fish and presents new data on morphine analgesia in fish. Recent anatomical and electrophysiological studies have demonstrated that fish are capable of nociception, the simple detection of a noxious, potentially painful stimulus and the reflex response to this. To prove pain perception, it must be demonstrated that an animal’s behaviour is adversely affected by a potentially painful event and this must not be a reflex response. The present study examined the acute effects of administering a noxious chemical to the lips of rainbow trout (Oncorhynchus mykiss) to assess what changes occurred …


The Relationship Between Health Status And Hope In Individuals With Hiv Disease, Celine Meera Chohan Sep 2003

The Relationship Between Health Status And Hope In Individuals With Hiv Disease, Celine Meera Chohan

All-Inclusive List of Electronic Theses and Dissertations

This study examined the relationship between hope and health status over a two-year period in individuals who were HIV -infected. One hundred and three individuals completed the surveys at entry into the study, at 12 months, and at 24 months. The Health Status Questionnaire (Wu et.al., 1991) measured Cognitive Functioning, Emotional Functioning, and Physical Functioning. Additionally, the Hope Scale (Snyder, 1991) and the Client Information Form were used to collect data. Results suggested hope at entry into the study was a significant predictor of physical functioning initially, at 12 months, and at 24 months. This finding suggests a link between …


Context-Aware Semantic Association Ranking, Boanerges Aleman-Meza, Christian Halaschek-Wiener, I. Budak Arpinar, Amit P. Sheth Sep 2003

Context-Aware Semantic Association Ranking, Boanerges Aleman-Meza, Christian Halaschek-Wiener, I. Budak Arpinar, Amit P. Sheth

Kno.e.sis Publications

Discovering complex and meaningful relationships, which we call Semantic Associations, is an important challenge. Just as ranking of documents is a critical component of today's search engines, ranking of relationships will be essential in tomorrow's semantic search engines that would support discovery and mining of the Semantic Web. Building upon our recent work on specifying types of Semantic Associations in RDF graphs, which are possible to create through semantic metadata extraction and annotation, we discuss a framework where ranking techniques can be used to identify more interesting and more relevant Semantic Associations. Our techniques utilize alternative ways of specifying the …


Social Learning Of Prey Location In Hatchery-Reared Atlantic Salmon, C. Brown, A. Markula, K. Laland Sep 2003

Social Learning Of Prey Location In Hatchery-Reared Atlantic Salmon, C. Brown, A. Markula, K. Laland

Aquaculture Collection

Naïve, hatchery-reared Atlantic salmon Salmo salar parr were paired with demonstrators that had been pre-trained to accept live prey from the surface or from the benthos. After 6 days of observing demonstrators through a clear perspex partition the naïve fish’s benthic foraging skills were tested. The results revealed that hatchery-reared Atlantic salmon can be taught to target benthic prey items by observation alone and social learning protocols can be utilized to dramatically increase benthic foraging success. The results are discussed with reference to refining hatchery-rearing practices with a view to improving the post-release survival of hatchery fishes. The role of …


Continuity Of Semantic Operators In Logic Programming And Their Approximation By Artificial Neural Networks, Pascal Hitzler, Anthony K. Seda Sep 2003

Continuity Of Semantic Operators In Logic Programming And Their Approximation By Artificial Neural Networks, Pascal Hitzler, Anthony K. Seda

Computer Science and Engineering Faculty Publications

One approach to integrating first-order logic programming and neural network systems employs the approximation of semantic operators by feedforward networks. For this purpose, it is necessary to view these semantic operators as continuous functions on the reals. This can be accomplished by endowing the space of all interpretations of a logic program with topologies obtained from suitable embeddings. We will present such topologies which arise naturally out of the theory of logic programming, discuss continuity issues of several well-known semantic operators, and derive some results concerning the approximation of these operators by feedforward neural networks.


The Benefits Of Breastfeeding: An Introduction For Health Educators, Sheila G. J. Clark, Timothy J. Bungum Sep 2003

The Benefits Of Breastfeeding: An Introduction For Health Educators, Sheila G. J. Clark, Timothy J. Bungum

Environmental & Global Health Faculty Research

Currently 16% of Americans breastfeed their children for at least 12 months as recommended by the AAP, which is well below the HP 2010 goal of 25%. Breastfed infants receive benefits that can improve their health throughout their lives. The benefits of breastfeeding for children include increased resistance to infectious diseases, such as gastroenteritis, respiratory tract infections, and ear infections. Breastfed children also display lower rates of chronic diseases including diabetes, obesity, asthma, and leukemia. The choice to breastfeed results in economic benefits from lower health care costs and from reduced spending on infant formula. The Healthy People 2010 targets …


A Longitudinal Examination Of Flow As A Predictor Of Recreational Exercise, Brian Michael Chichester Sep 2003

A Longitudinal Examination Of Flow As A Predictor Of Recreational Exercise, Brian Michael Chichester

Loma Linda University Electronic Theses, Dissertations & Projects

Flow state is a valued psychological state of enjoyment and well-being. It is characterized by feelings of intrinsic self-reward and marked by nine dimensions theorized to contribute to flow state. Flow has been studied mostly in elite athletes, whom report highly lucid flow experiences; to a much lesser extent it has been studied in recreational exercisers. Most prior research methodologies involve experience sampling or qualitative techniques, such as interviewing. Only one demonstrably valid and reliable flow instrument is widely available for efficient, quantitative measure of flow experiences. This study measures flow longitudinally in a recreational exercising population by comparing a …


The Psychological Characteristics Of Obese Children, Thomas Taylor Mitchell Sep 2003

The Psychological Characteristics Of Obese Children, Thomas Taylor Mitchell

Loma Linda University Electronic Theses, Dissertations & Projects

Several studies along with the surgeon general of the United States have identified obesity as a national health issue. Research indicates that adult obesity treatment has relatively poor long-term effects. Consequently increased attention has been given to addressing obesity in children. This focus is particularly vital due to the fact that children are one of the populations showing the most rapid increase in overweight and obesity. The purpose of this study was to identify the some of the unique psychological characteristics of obese children by analyzing the intake data of children and adolescents attending the Loma Linda University Growing Fit …


Radiation Effects On Dopamine-Mediated Prepulse Inhibition In The C57bl/6 Mouse, Cara Nicole Zuccarelli Miller Sep 2003

Radiation Effects On Dopamine-Mediated Prepulse Inhibition In The C57bl/6 Mouse, Cara Nicole Zuccarelli Miller

Loma Linda University Electronic Theses, Dissertations & Projects

This study examined the effects of proton and gamma radiation on a dopamine-dependent sensory gating mechanism: prepulse inhibition of the startle reflex. The purpose of this research was to describe potential hazards of proton radiation to the central nervous system in long-term space fight and for proton therapy patients. Results from previous research indicate that startle behavior is modified by proton and iron radiation. Forty-eight 10-½ week old, male C57BL/6 mice were used to characterize the optimal parameters for the model (prepulse duration, probe duration, and stimulus-onset-asynchrony). Three hundred and fifty two mice were used to characterize the time course …

Draft Plan Of Management For The Proposed Point Quobba Fish Habitat Protection Area., Department Of Fisheries Aug 2003

Draft Plan Of Management For The Proposed Point Quobba Fish Habitat Protection Area., Department Of Fisheries

Fisheries Management Papers

Point Quobba is a popular site for locals and tourists for beach activities, fishing and snorkelling, and as a place for children to learn to swim and gain an awareness of the marine environment. The marine life and habitats of the area are of considerable scientific and recreational interest and are highly valued in the local community. However, they are at risk from their high level of use and from conflict between users due to their proximity to popular tourism, boat ramp, camping and settlement areas on-shore.


Sustainable Agricultural Growth In The Al-Ahsa Oasis Of Saudi Arabia: Harmonizing Wto Goals, Environmental Constraints, And National Food Security Issues, Ahmad Mohammad Al-Mass Aug 2003

Sustainable Agricultural Growth In The Al-Ahsa Oasis Of Saudi Arabia: Harmonizing Wto Goals, Environmental Constraints, And National Food Security Issues, Ahmad Mohammad Al-Mass

All-Inclusive List of Electronic Theses and Dissertations

Local agricultural practices in Saudi Arabia today are shaped by local land, labor, and technological conditions, by national governmental regulations, subsidies, and price controls, and by the global impacts of foreign competition and goals of international organizations such as the World Trade Organization (WTO). Human and natural forces over which local oasis residents have no control exert more influence upon their social and economic life than do daily agricultural tasks. These forces are recognized by Saudi national planners, for agricultural development is very important to the government and to oasis dwellers in Saudi Arabia. Reducing the loss of foreign exchange, …


Boltzmann Machine Learning With The Latent Maximum Entropy Principle, Shaojun Wang, Dale Schuurmans, Fuchun Peng, Yunxin Zhao Aug 2003

Boltzmann Machine Learning With The Latent Maximum Entropy Principle, Shaojun Wang, Dale Schuurmans, Fuchun Peng, Yunxin Zhao

Kno.e.sis Publications

We present a new statistical learning paradigm for Boltzmann machines based on a new inference principle we have proposed: the latent maximum entropy principle (LME). LME is different both from Jaynes maximum entropy principle and from standard maximum likelihood estimation. We demonstrate the LME principle BY deriving new algorithms for Boltzmann machine parameter estimation, and show how robust and fast new variant of the EM algorithm can be developed. Our experiments show that estimation based on LME generally yields better results than maximum likelihood estimation, particularly when inferring hidden units from small amounts of data.

A Visual Framework Invites Human Into The Clustering Process, Keke Chen, Ling Liu Jul 2003

A Visual Framework Invites Human Into The Clustering Process, Keke Chen, Ling Liu

Kno.e.sis Publications

Clustering is a technique commonly used in scientific research. The task of clustering inevitably involves human participation - the clustering is not finished when the computer/algorithm finishes but the user has evaluated, understood and accepted the patterns. This defines a human involved "clustering-analysis/evaluation" iteration. Instead of neglecting this human involvement, we provide a visual framework (VISTA) with all power of algorithmic approaches (since their result can be visualized), and in addition we allow the user to steer/monitor/refine the clustering process with domain knowledge. The visual-rendering result also provides a precise pattern for fast post-processing.

Student Physical Activity Patterns: Grade, Gender, And Activity Influences, Pamela Hodges Kulinna, Jeffrey J. Martin, Qin Lai, Amy Kliber, Brett Reed

Kinesiology, Health and Sport Studies

The purpose of this study was to determine how physical education students' cardiovascular responses as determined by mean heart rate, standard deviation of heart rate, and percentage of time in target heart rate zone varied according to student characteristics. Participants were 505 students in Grades 3 through 12. The Polar Accurex Plus heart rate telemetry system was used to measure the physiological load on the cardiovascular system. Three-way ANOVA results suggested that heart rate patterns in physical education varied according to gender, grade, and activity. For example, secondary school girls were more active in individual activities while secondary school boys …

Behavioral Evaluation Of The Psychological Welfare And Environmental Requirements Of Agricultural Research Animals: Theory, Measurement, Ethics, And Practical Implications, Lesley A. King Jul 2003

Behavioral Evaluation Of The Psychological Welfare And Environmental Requirements Of Agricultural Research Animals: Theory, Measurement, Ethics, And Practical Implications, Lesley A. King

Experimentation Collection

The welfare of agricultural research animals relies not only on measures of good health but also on the presence of positive emotional states and the absence of aversive or unpleasant subjective states such as fear, frustration, or association with pain. Although subjective states are not inherently observable, their interaction with motivational states can be measured through assessment of motivated behavior, which indicates the priority animals place on obtaining or avoiding specific environmental stimuli and thus allows conclusions regarding the impact of housing, husbandry, and experimental procedures on animal welfare. Preference tests and consumer demand models demonstrate that animal choices are …

Trying To Fix The Development In Evolutionary Developmental Psychology, David S. Moore Jul 2003

Trying To Fix The Development In Evolutionary Developmental Psychology, David S. Moore

Pitzer Faculty Publications and Research

If we agree for a moment that there is such a thing as human nature, we immediately encounter an extraordinarily thorny question: Where does our nature come from? This question drives David Bjorklund and Anthony Pellegrini’s new book The Origins of Human Nature: Evolutionary Developmental Psychology. The question is so challenging, in part, because human nature reflects at least two conceptually distinct processes: evolution and development. The former, which operates across generations, allows the continued existence of characteristics that permitted survival and reproduction in our ancestors; the latter, which operates during a person’s lifetime, contributes to the appearance of …

18 | Salvage Excavations At The Early Bronze Age Site Of Qiryat Ata, Amir Golani Jul 2003

18 | Salvage Excavations At The Early Bronze Age Site Of Qiryat Ata, Amir Golani

IAA Reports—Monograph Series of the Israel Antiquities Authority

Some 1400 sq m were exposed in the IAA excavations of the protohistoric site of Qiryat Ata. The study of the paleogeography reveals this location was an optimal area for exploitation of natural resources, including alluvial valleys, coastal habitats and forests, with stable water sources and extensive available farmland. The site yielded a wealth of stratified, well-dated architecture in a chronological sequence within the Early Bronze Age, illustrating the development from EB IB curvilinear structures, to late EB IB rectilinear forms with rounded corners, and finally EB II angular-cornered rectilinear buildings in a large, dense, urbanized town. The rich pottery, …


Access To Credit, Plot Size And Cost Inefficiency Among Smallholder Tobacco Cultivators In Malawi, Gautam Hazarika, Jeffrey Roger Alwang Jul 2003

Access To Credit, Plot Size And Cost Inefficiency Among Smallholder Tobacco Cultivators In Malawi, Gautam Hazarika, Jeffrey Roger Alwang

School of Economics and Finance Faculty Publications

Using data from the Malawi Financial Markets and Household Food Security Survey, this paper examines the effect of access to credit from formal sources, and tobacco plot size, on cost inefficiency among Malawian smallholder tobacco cultivators. Farm-specific cost inefficiency is estimated within the framework of stochastic frontier analysis. Access to credit is measured as the sum of household members' self-reported credit limits at credit organisations, arguably a truer measure of an exogenous credit constraint than credit program participation or actual loan uptake. It is found that tobacco cultivation is significantly less cost inefficient per acre on larger plots. While access …


Do Fishes Have Nociceptors? Evidence For The Evolution Of A Vertebrate Sensory System, Lynne U. Sneddon, Victoria A. Braithwaite, Michael J. Gentle Jun 2003

Do Fishes Have Nociceptors? Evidence For The Evolution Of A Vertebrate Sensory System, Lynne U. Sneddon, Victoria A. Braithwaite, Michael J. Gentle

Veterinary Science and Medicine Collection

Nociception is the detection of a noxious tissue-damaging stimulus and is sometimes accompanied by a reflex response such as withdrawal. Pain perception, as distinct from nociception, has been demonstrated in birds and mammals but has not been systematically studied in lower vertebrates. We assessed whether a fish possessed cutaneous nociceptors capable of detecting noxious stimuli and whether its behavior was sufficiently adversely affected by the administration of a noxious stimulus. Electrophysiological recordings from trigeminal nerves identified polymodal nociceptors on the head of the trout with physiological properties similar to those described in higher vertebrates. These receptors responded to mechanical pressure, …


Habitat-Predator Association And Avoidance In Rainbowfish (Melanotaenia Spp.), Culum Brown Jun 2003

Habitat-Predator Association And Avoidance In Rainbowfish (Melanotaenia Spp.), Culum Brown

Sentience Collection

The ability to recall the location of a predator and later avoid it was tested in nine populations of rainbowfish (Melanotaenia spp.), representing three species from a variety of environments. Following the introduction of a model predator into a particular microhabitat, the model was removed, the arena rotated and the distribution of the fish recorded again. In this manner it could be determined what cues the fish relied on in order to recall the previous location of the predator model. Fish from all populations but one (Dirran Creek) were capable of avoiding the predator by remembering either the location and/or …
