We report on results of agglomeration experiments for the Ag/SiO2/Si(100) system. Thin silver films, 100 nm in thickness, were annealed, and their electrical resistance was continuously monitored using a four-point probe technique. Scanning electron microscopy and digital image analysis were used to correlate the time-dependent agglomeration morphology to the sheet resistance of the Ag thin film. Our results indicated that the area fraction of the surface uncovered during agglomeration scaled linearly in time. We found that at fixed annealing temperature, the normalized sheet resistance followed power-law scaling in time, i.e., R∼|t−τ|−μ, (μ=1.25±0.1) where τ corresponds to the time it takes to reach electrical failure of the sample.
BackgroundSingle-session counseling is being implemented across Canada to increase the accessibility and availability of mental health services. Despite increasing use, existing research on single-session counseling is sparse and has methodological limitations. In addition, some stakeholders are skeptical that this model of care can support meaningful change for clients.ObjectiveThe aim of this study is to evaluate a new single-session counseling program (called Same-Day Counseling) offered in an outpatient community mental health clinic in Northwestern Ontario, Canada.MethodsClients who attend Same-Day Counseling services will be given the opportunity to participate in the program evaluation. Those who consent will complete measures before their session, after their session, and at 1-month follow-up. Data will provide information on who accesses Same-Day Counseling (eg, typical presenting problems, symptom severity), client satisfaction with services, and whether clients benefit from the services (eg, improved functioning and reduced symptom severity).ResultsData collection is underway with 80 participants having completed baseline measures and 55 participants having completed follow-up measures. Data collection is expected to conclude in December 2015.ConclusionsThis study is designed to contribute to the literature regarding the integration of single-session counseling into ongoing mental health services, with additional attention to methodological rigour. Our approach will help to address ongoing concerns regarding the implementation of single-session counseling, and inform health care providers and policy makers regarding the utility of this model for addressing the mental health care need of the community.
This article examines the impact of a curricular infusion strategy aimed at integrating gerontological practice issues into social work education. Findings (N = 83) illustrate that student interest, knowledge, and skills in aging practice increased immediately following implementation of a three-tiered infusion approach; however, ongoing exposure to gerontology in and out of the classroom appears necessary to sustain students' interest in working with older adults over time. Although the majority of students endorsed aging issues as important to social work in general, many did not understand its relevance to their own careers. Next steps are outlined to enable students to make this important connection.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
