A Conceptual Model Of The Corporate Decision-Making Process Of Sport Sponsorship Acquisition, David Arthur, Don Scott, Terry Woods Jul 1997

A Conceptual Model Of The Corporate Decision-Making Process Of Sport Sponsorship Acquisition, David Arthur, Don Scott, Terry Woods

Terry Woods

The general acceptance of sport sponsorship by corporate and sporting worlds alike has led to a situation whereby corporations receive from hundreds to thousands of unsolicited proposals annually. Despite this, there is a general lack of systematic research into sport sponsorship with little information in existence as to how corporations decide between alternative properties. In an attempt to address this situation, this paper develops a conceptual model of the sport sponsorship acquisition process based on the basic tenets of organizational purchasing behavior, contemporary literature on sport sponsorship, and the results of a qualitative study. It is anticipated that the Sport …

The Use Of Gutta-Percha Point To Locate The Origin Of Facial Sinus, W.C. Ngeow Jun 1997

The Use Of Gutta-Percha Point To Locate The Origin Of Facial Sinus, W.C. Ngeow

Wei Cheong Ngeow

Infection from the wisdom teeth usually causes severe swelling at the region of the angle and body of the mandible. Occasionally, it tracts outward to form a cervicofacial sinus. This paper demonstrates the use of gutta-percha point to locate the origin of a cervicofacial sinus due to an asymptomatic impacted wisdom tooth. The advantage of using gutta-percha point is discussed.

Effect Size And Power For Clinical Trials Using Years Of Healthy Life As The Primary Endpoint, Paula Diehr Jun 1997

Effect Size And Power For Clinical Trials Using Years Of Healthy Life As The Primary Endpoint, Paula Diehr

Paula Diehr

Some clinical trials perform repeated measurements on patients over time, plot those measures against time, and summarize the results in terms of the area under the curve. If the measured variable is health status, the summary outcome is sometimes referred to as years of healthy life (YHL), or quality-adjusted life years (QALY). This paper investigates some theoretical and practical aspects of randomized trials designed to assess measures such as YHL. We first derived algebraic expressions for the effect size of YHL measures under several theoretical models of the treatment's effect on health. We used these expressions to examine how the …

Effect Of Thermocycling On The Fracture Toughness Of Composites, Noor Hayaty Abu Kasim Abu Kasim N.H. May 1997

Effect Of Thermocycling On The Fracture Toughness Of Composites, Noor Hayaty Abu Kasim Abu Kasim N.H.

Noor Hayaty Abu Kasim Abu Kasim N.H.

Fracture toughness has been recognised to be one of the most important mechanical property for retorative materials. It is the aim of this study to investigate the effect of thermocycling an fracture toughness of a range of dental composites; P50(P)1 , Silux Plus(S)2, Heliomolar(H)3, Clearfil Photo Posterior-light activated(CLA)4 and Clearfil Posterior-chemically activated(CC)3. 110 rectangular pre-notched specimens was prepared for each material utilising a stainless steel mould. The specimens were divided into 11 groups of 10 each. Test groups 1-6 were subjected to 0, 250, 500, 750, 1000 and 10,000 thermal cycles respectively. All specimens were subjected to a 3 point …

Isolation Of A Mannose-Binding And Ige- And Igm-Reactive Lectin From The Seeds Of Artocarpus Integer, Onn Haji Hashim Jan 1997

Isolation Of A Mannose-Binding And Ige- And Igm-Reactive Lectin From The Seeds Of Artocarpus Integer, Onn Haji Hashim

Onn Haji Hashim

A mannose-binding lectin, termed champedak lectin-M, was isolated from an extract of the crude seeds of champedak (Artocarpus integer). On gel filtration chromatography, the lectin eluted in a single peak at elution volumes corresponding to 64 kDa, SDS-PAGE showed the mannose-binding lectin to be composed of 16.8 kDa polypeptides with some of the polypeptides being disulphide-linked to give dimers. When tested with all isotypes of immunoglobulins, champedak lectin-M demonstrated a selective strong interaction with human IgE and IgM, and a weak interaction with IgA2, The binding interactions of lectin-M were metal ion independent. The lectin was also shown to interact …

Microleakage Testing, Noor Hayaty Abu Kasim Abu Kasim N.H. Jan 1997

Microleakage Testing, Noor Hayaty Abu Kasim Abu Kasim N.H.

Noor Hayaty Abu Kasim Abu Kasim N.H.

Microleakage testing has been used to determine the possible clinical performance of a restorative material. Many microleakage testing materials have been developed and performed through the years. There has been no agreement as to which testing methodology would give the most accurate results. Attempts have been made to simulate the oral conditions and to give a more quantitative representation of micro leakage. The different micro leakage testing methodologies are presented in this paper.

A Rolling-Ball Device For Producing Surface Fatigue And Its Application To Dental Materials, Noor Hayaty Abu Kasim Abu Kasim N.H. Jan 1997

A Rolling-Ball Device For Producing Surface Fatigue And Its Application To Dental Materials, Noor Hayaty Abu Kasim Abu Kasim N.H.

Noor Hayaty Abu Kasim Abu Kasim N.H.

A new method of producing and evaluating surface fatigue using a rolling-ball device has been developed. The method involves constraining a rolling ruby ball between the ''v'' groove of a rotor and the test specimen. The ball applies a compressive stress to the surface of the test material whilst it rolls in a circular pattern across the specimen surface. The fatigue life is defined as the time taken for surface degradation to begin to occur. The method is simple and reproducible and allows fatigue data to be gathered using a relatively small number of specimens. A series of model dental …

Neuroendocrine Aspects Of Primary Endogenous Depression Xv. Mathematical Modeling Of Nocturnal Melatonin Secretion In Major Depressives And Normal Controls, L. Kathleen Sekula, Joseph F. Lucke, E. Kevin Heist, R. Kenneth Czambel, Robert T. Rubin Jan 1997

Neuroendocrine Aspects Of Primary Endogenous Depression Xv. Mathematical Modeling Of Nocturnal Melatonin Secretion In Major Depressives And Normal Controls, L. Kathleen Sekula, Joseph F. Lucke, E. Kevin Heist, R. Kenneth Czambel, Robert T. Rubin

Joseph Lucke

We previously reported a trend toward a higher mean nocturnal serum melatonin (MEL) concentration, based on 30-min blood sampling over 24 h, in 23 female definite endogenous depressives compared to 23 matched normal female control subjects, and no significant difference in 15 male depressives compared to their controls (Rubin et al., 1992). In both groups of patients vs. their controls, there also were trends toward an earlier MEL rise time, by about 30 min, and a later MEL peak time, by about 90 min. Because the offset of MEL secretion was not estimated in that study, the total duration of …

Sexual Orientation: A Cultural Diversity Issue For Nursing, Tr Misener, Rl Sowell, Kenneth D. Phillips, C.M. Harris Jan 1997

Sexual Orientation: A Cultural Diversity Issue For Nursing, Tr Misener, Rl Sowell, Kenneth D. Phillips, C.M. Harris

Kenneth D. Phillips

Traditional approaches to cultural diversity and the development of a culturally aware workforce have consistently ignored the importance of gender role orientation and sexual orientation as sources of potential conflict in the work environment. To maintain its integrity as a caring profession, nursing must take steps to end personal and professional discrimination on the basis of sexual orientation.
