Stigma has negative consequences for quality of life and HIV care outcomes. PositiveLinks is a mobile health intervention that includes a secure anonymous community message board (CMB). We investigated discussion of stigma and changes in stigma scores. Of 77 participants in our pilot, 63% were male, 49% Black, and 72% had incomes below the federal poverty level. Twenty-one percent of CMB posts (394/1834) contained stigma-related content including negative (experiencing stigma) and positive (overcoming stigma) posts addressing intrapersonal and interpersonal stigma. Higher baseline stigma was positively correlated with stress and negatively correlated with HIV care self-efficacy. 12-month data showed a trend toward more improved stigma scores for posters on the CMB versus non-posters (− 4.5 vs − 0.63) and for posters of stigma-related content versus other content (− 5.1 vs − 3.3). Preliminary evidence suggests that a supportive virtual community, accessed through a clinic-affiliated smartphone app, can help people living with HIV to address stigma.
The equivalent annual cost (EAC) method is a useful tool in asset pricing, lease financing and corporate investment. It deals with projects with different economic lives and has wide applications in many fields outside the finance or even business. However, the important EAC concept and its applications are not always very well understood even within the finance academia. There are a few misunderstandings surrounding 1this widely taught and practiced methodology as evidenced by our experience with finance professionals over the past decades and the lack of clarity in all the mainstream textbooks we have surveyed. One of them is the misconception that the EAC method requires infinite time horizon and infinite repetitions of the identical project or equipment. Given its importance and wide application, the finance profession has an obligation to serve well its gatekeeper role by not overlooking these misconceptions. Thus far, no one has raised and addressed these misconceptions. We fill in this void by explicitly revealing, explaining and addressing these misconceptions. Specifically, we argue that infinite horizon is a convenience but not a necessity by showing how the method can be used for projects or assets with finite horizons and what cautions one has to take. We also provide threads for future studies along this line. Our work makes a marginal contribution the finance theory, pedagogy and practice.
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.
