Adair (c) Keywords: Adolescent obesity; Obesity prevention messages; Health promoting messages; Social marketing Abstract: Drug abuse, smoking, and disordered eating literature reveal that some health promoting messages can induce unintended or harmful effects on the target audience. Scholars recommend careful messaging in social marketing campaigns, by shifting the focus away from health outcomes. This study tests the effects of adolescent-targeted obesity prevention messages (body-image, health benefit) with positive experience and unrelated messages on health behavior intentions and unintended effects. A pre-post experiment (N =95) reveals that body-image public service advertisements (PSAs) may increase anxiety when compared to unrelated PSAs (no main effect, significant planned comparisons are found). Health benefit PSAs are more readable (F =4.59, p Author Affiliation: (a) Alberta Cancer Board, Alberta Health Services, Holy Cross Site, Phase II, 5th Fl., 2210 2nd Street SW, Calgary, AB, Canada T2S 3C3 (b) Faculty of Management, University of Lethbridge, 4401 University Dr W, Lethbridge, AB, Canada T1K 3M4 (c) Departments of Psychiatry and Community Health Sciences, University of Calgary, 3330 Hospital Dr NW, Calgary, AB, Canada T2N 4N1 Article History: Received 1 January 2009; Revised 1 January 2009; Accepted 1 February 2009

Polypropylene (PP) based materials for nonreusable syringe applications have been investigated, some of them containing an internal liquid lubricant. Hardness, tensile properties, and friction measured by two distinct procedures have been determined. We report three series of results: for nonirradiated samples; for samples directly after stopping the irradiation; and also for samples after accelerated aging equivalent to 2 years of shelf life. We find that effects of irradiation and aging on Shore A and Shore D hardness are small. Tensile strength at break, elongation at yield, and elongation at break all decrease after irradiation and then decrease still more after aging; these results are quantified but expected. By contrast, results from pin-on-disk tribometry are quite varied. In some cases γ irradiation and aging both increase friction, in other cases both decrease friction. We also have a case when irradiation increases friction while aging decreases it--as well as vice versa. Possible mechanisms of all these types of behavior are advanced. POLYM. ENG. SCI., 49:1035-1041, 2009. [C]2009 Society of Plastics Engineers, INTRODUCTION AND SCOPE Gamma irradiation is known to have significant effects on properties of polymers and polymer-containing composites (1-18). At the same time, such irradiation is the most frequently applied [...]

Over the past few years, the chemical mechanical planarization (CMP) community has systematically characterized the device reliability issues associated with the introduction of copper metallization into integrated circuit fabrication. To gain further understanding of the impact of CMP processing on device performance, this paper reports in detail the interactions of simulated copper slurries and pristine segmented polyurethanes. These studies clearly show that polyurethane is fundamentally incompatible with some of the chemicals used in copper CMP, such as hydrogen peroxide. Experimental copper polishing data on both polyurethane and polyolefin-based pads are compared. The pad performance differences between the polyurethane and polyolefin--based pads are explained based on the chemistry of the base polymers used in the pad fabrication. These results are incorporated into the design and fabrication of a new class of polyolefins-based application specific pads. Index Terms--Chemical mechanical planarization (CMP), copper, pads, reliability.

A study was conducted on the physiology and transcriptome dynamics of the metal ion-reducing bacterium Shewanella oneidensis strain MR-1 in response to nonradioactive strontium (Sr) exposure. Results showed an extra-cellular sequestration of Sr, with at least a portion of the heavy metal associated with carbonate phases.

A study is carried out to report the self-assembly of cerium oxide nanoparticles to nanorods. The formation of cylindrical supraaggregates and their subsequent growth by preferential assembling of ceria nanocrystallites along the longitudinal direction was proposed to be the probable mechanism of spontaneous self-assembly of nanorods.

A chemical method for synthesizing boehmite nanofibers by a modified sol-gel process involving aluminum isopropoxide precursor is discussed. The boehmite nanofibers and gamma-alumina nanorods were characterized by X-ray photoelectron spectroscopy.

Media influences on civic and consumer culture while considering the interrelationships of consumer attitudes and behaviors with civic participation using the 2000 DDB Life Style Study is examined. The personal needs emphasized by product-saturated mass media diminish civic-mindedness by creating as individualistic consumption-oriented culture.
