Processes Controlling Metal Transport And Retention As Metal-Contaminated Groundwaters Efflux Through Estuarine Sediments, Stuart L. Simpson, Edward J. Maher, Dianne F. Jolley

Faculty of Science - Papers (Archive)

Factors affecting the transport and retention of Cd, Cr, Cu, Ni, Pb and Zn in acidic groundwaters as they pass through estuarine sediments were investigated using column experiments. Acidic groundwaters caused the rapid dissolution of iron sulfide (AVS) and other iron and manganese phases from sediments that are important for metal binding and buffering. Metal breakthrough to overlying water occurred in the order of Ni>Zn>Cd>>Cu>>Cr/Pb. Metal transport increased as the sediment permeability increased, reflecting the low resistance to flow caused by larger sand-sized particles and the decreased abundance of metal adsorption sites on these materials. Metal …

Protecting Group Effects On The Efficiency Of The Ruthenium-Catalyzed Alder-Ene Reaction, Joseph Hartley, Stephen G. Pyne

Faculty of Science - Papers (Archive)

The efficiency of the ruthenium-catalysed Alder-ene reaction of hydroxy alkenes depends heavily on the nature of the O-protecting groups employed as well as the length of the carbon spacer between the hydroxy and alkene group.

An Exploratory Study Of Older Adults' Perceptions Of Dtca For Prescription Medications, Sandra C. Jones, Judy Mullan

Faculty of Health and Behavioural Sciences - Papers (Archive)

There are many arguments for and against Direct-To-Consumer-Advertising (DTCA) and their impact on the consumer. A study involving 97 older consumers was carried out to investigate their perceptions about long or short versions of written DTCA for arthritis or diabetes medication. The results indicate that even though the ads may improve doctor-patient discussion about medications, they would not necessarily empower them to make decisions. Some of the consumers also believed that DTCA might cause people to ask for inappropriate medicines, become confused and possibly stop seeking medical advice.

An Exploratory Study On The Effect Of Positive (Warmth Appeal) And Negative (Guilt Appeal) Print Imagery On Donation Behaviour In Animal Welfare, M. Haynes, Jennifer Thornton, Sandra C. Jones

Faculty of Health and Behavioural Sciences - Papers (Archive)

Very few studies in social marketing empirically compare the effectiveness of positive and negative appeals. This study examines the effect of positive (warmth appeal) and negative (guilt appeal) print imagery on donation behaviour to an animal welfare organisation. A quasiexperimental design was used to test the appeals, using a convenience sample of 282 university students, with each experimental group being exposed to only one type of appeal. The results indicated that negative imagery which evoked guilt was more effective than positive imagery which evoked warmth, on intention to donate money and time to the animal welfare organisation.

The Influence Of Magazine Advertising On Parents' Nutrition Ratings Of Food Products For Children, Christina Hoang, Sandra C. Jones, Jennifer Thornton

Faculty of Health and Behavioural Sciences - Papers (Archive)

Childhood obesity currently affects approximately 22 million children under the age of five worldwide (Rochinni, 2002) and its increasing prevalence in developed nations makes it one of the most common nutritional problems among children (Sorof and Stephen, 2002). A study was conducted to investigate parents’ health-related perceptions for a series of magazine advertisements for commonly advertised and popular children’s food products. The study revealed that confusion exists among parents and this was most evident in relation to the energy content of food products. Parents are important due to the instrumental role they play in their child’s nutrition - both as …

The Southwestern Association Of Parasitologists: The First 35 Years: 1967–2002, Donald W. Duszynski

Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications

First two paragraphs:

It is likely that the idea to organize southwestern parasitologists into a regional group originated over cocktails one night in the late 1950s during a regional or national meeting. What is clear is that two men—Drs. Robert E. Kuntz and Donald V. Moore— were instrumental in turning the idea into what has become, in reality, the Southwestern Association of Parasitologists (SWAP).

Dr. J. Teague Self (personal communication, 1981) stated, “The beginning of SWAP was an idea of Robert Kuntz who felt that something could be gained if several of us here in the southwest could get together …

Levels Of Citation Of Nonhuman Animal Studies Conducted At A Canadian Research Hospital, Anne Innis Dagg, Troy K. Seidle

Experimentation Collection

The publication of scientific articles that receive few or no citations raises questions of the appropriate use of resources as well as ethics. In the case of animal research, the ethics issue extends beyond human patients to nonhuman animals, as the research subjects them to pain and, typically, to death. This study is a citation analysis of animal research conducted at Toronto's Hospital for Sick Children (HSC). Of the 594 publications (1990 to 1995) on animal research by affiliates of HSC, 29% received Iower than 10 citations in a 10-year period. We compare the research history of 13 "best" and …

On The Decidability Of The Termination Problem Of Active Database Systems, James Bailey, Guozhu Dong, K. Rammamohanarao

Kno.e.sis Publications

Active database systems enhance the functionality of traditional databases through the use of active rules or ‘triggers’. One of the principal analysis questions for such systems is that of termination—is it possible for the rules to recursively activate one another indefinitely, given an initial triggering event. In this paper, we study the decidability of the termination problem, our aim being to delimit the boundary between the decidable and the undecidable. We present results for two broad types of variations, variations in rule syntax and variations in meta level features. Within each of these, we identify members close to the …

Discovering And Ranking Semantic Associations Over A Large Rdf Metabase, Christian Halaschek-Wiener, Boanerges Aleman-Meza, I. Budak Arpinar, Amit P. Sheth

Kno.e.sis Publications

Information retrieval over semantic metadata has recently received a great amount of interest in both industry and academia. In particular, discovering complex and meaningful relationships among this data is becoming an active research topic. Just as ranking of documents is a critical component of today's search engines, the ranking of relationships will be essential in tomorrow's semantic analytics engines. Building upon our recent work on specifying these semantic relationships, which we refer to as Semantic Associations, we demonstrate a system where these associations are discovered among a large semantic metabase represented in RDF. Additionally we employ ranking techniques to provide …

Inhibition Of Nitric Oxide Inhibition Of Nitric Oxide Synthase Does Not Alter Dynamic Cerebral Autoregulation In Humans, Rong Zhang, Thad E. Wilson, Sarah Witkowski, Jian Cui, Craig G. Crandall, Benjamin D. Levine

Exercise and Sport Studies: Faculty Publications

The aim of this study was to determine whether inhibition of nitric oxide synthase (NOS) alters dynamic cerebral autoregulation in humans. Beat-to-beat blood pressure (BP) and cerebral blood flow (CBF) velocity (transcranial Doppler) were measured in eight healthy subjects in the supine position and during 60° head-up tilt (HUT). NOS was inhibited by intravenous N G-monomethyl-L-arginine (L-NMMA) infusion. Dynamic cerebral autoregulation was quantified by transfer function analysis of beat-to-beat changes in BP and CBF velocity. Pressor effects of L-NMMA on cerebral hemodynamics were compared with those of phenylephrine infusion. In the supine position, L-NMMA increased mean BP from 83 ± …

Semantic Visualization: Interfaces For Exploring And Exploiting Ontology, Knowledgebase, Heterogeneous Content And Complex Relationships, Amit P. Sheth, David Avant

Kno.e.sis Publications

Technology platforms and products for ontology-driven process of semantic applications that serve both Enterprise wide and pan-Web needs are both available and being deployed. Similar to the development of enterprise software applications, the creation of an ontology driven semantic application can be described as a set of distinct phases that compose a lifecycle. From conception to deployment, these phases involve human interaction with a broad variety of information, identified as heterogeneous data, metadata, knowledge and ontology. Based on experience spanning academic research at the LSDIS lab through deployed commercial semantic applications based on Semagix Freedom, this paper provides examples of …

A Conceptual Framework For Non-Kin Food Sharing: Timing And Currency Of Benefits, Jeffrey R. Stevens, Ian C. Gilby

Jeffrey Stevens Publications

Many animal species, from arthropods to apes, share food. This paper presents a new framework that categorizes nonkin food sharing according to two axes: (1) the interval between sharing and receiving the benefits of sharing, and (2) the currency units in which benefits accrue to the sharer (especially food versus nonfood). Sharers can obtain immediate benefits from increased foraging efficiency, predation avoidance, mate provisioning, or manipulative mutualism. Reciprocity, trade, status enhancement and group augmentation can delay benefits. When benefits are delayed or when food is exchanged for nonfood benefits, maintaining sharing can become more difficult because animals face discounting and …

The Selfish Nature Of Generosity: Harassment And Food Sharing In Primates, Jeffrey R. Stevens

Jeffrey Stevens Publications

Animals may share food to gain immediate or delayed fitness benefits. Previous studies of sharing have concentrated on delayed benefits such as reciprocity, trade and punishment. This study tests an alternative model (the harassment or sharing–under–pressure hypothesis) in which a food owner immediately benefits because sharing avoids costly harassment from a beggar. I present an experiment that varies the potential ability of the beggar to harass, and of the owner to defend the food, to examine the effects of harassment on food sharing in two primate species: chimpanzees (Pan troglodytes) and squirrel monkeys (Saimiri boliviensis). For …
