<b><i>Aim:</i></b> The aim of this study was to discuss and illustrate the role age-conditional probability has in communicating risk of developing ocular and ocular adnexal malignancies. <b><i>Methods:</i></b> Cross-sectional incidence for retinoblastoma, uveal melanoma, conjunctival melanoma, and lacrimal gland carcinomas from 2000 to 2017 were obtained from the Surveillance, Epidemiology and End Results (SEER) database. Incidence rates were age-adjusted to the 2000 United States population. Age-adjusted incidence was converted to age-interval and cumulative risks. Outcomes were examined in 20-year intervals and cumulatively for adult cancers and yearly for retinoblastoma. <b><i>Results:</i></b> The risk of each malignancy displayed age-dependent variation. For adult malignancies, men were at higher risk at most age intervals. Uveal melanoma had the greatest cumulative lifetime risk. The probability of developing retinoblastoma declines precipitously after age 3 years. <b><i>Conclusions:</i></b> Age-conditional probability of developing cancer is a conceptually friendly means of understanding and communicating risk. It is particularly useful in comparing the risks of uncommon or rare cancers, such as those found in and around the eye. The assessment of risk in terms of age-conditional probability is a versatile and an underutilized pedagogical tool.

Purpose – The purpose of this paper is to examine the information channels used by public and nonprofit organizations to communicate disaster risk information to Colonias residents in Hidalgo County, Texas. It seeks to find creative and proactive solutions for organizations to improve risk education to these constituents. Design/methodology/approach – Initially a snowball sampling technique was used to conduct six face-to-face interviews. This was followed by an online survey sent to 64 reputational referrals, of which 23 completed the survey, generating a response rate of 34 percent. A comparative analysis between public and nonprofit organizations and the Fischer's exact test were employed to analyze the data. Findings – Channel preferences for providing risk information varied with public organizations using the television (TV) and the nonprofit organizations using bilingual staff for outreach. The television, radio, public events, and bilingual staff were considered to be the most effective while social media (Facebook, Twitter, and city web sites) was not considered at all by both groups. Lack of funding and staffing problems were identified as the primary challenges. Research limitations/implications – One limitation is that the paper focusses on organizations serving Spanish speakers in the Texas Colonias. Future research needs to investigate how other localities at border sites where culturally and linguistically diverse groups might reside, receive and understand risk information. The role of cross-national organizations in creating internationally coordinated plans for disaster communication should also be explored. Originality/value – It highlights the challenges faced by organizations in communicating risk, especially in border communities where culturally and linguistically diverse groups reside.

<p xss=removed><span lang="EN-US" xss=removed>Health risks, such as the probability of experiencing a side effect from a medication, are typically communicated numerically. However, presenting risks in strictly numeric formats is problematic considering that the public often experiences difficulty in comprehending strictly numeric probabilities. To help overcome this problem, Leonhardt and Keller (2018) tested the efficacy of using pictographs to visually present probabilistic information to health consumers. They found that the addition of pictographs alongside numeric probability information increased probability comprehension and lessened the perceived risk of a multiple risk health option. Here, we review relevant work on probability format and build on the general evaluability theory to posit why pictographs may result in lower risk perceptions of multiple risk options. We discuss current limitations in our understanding of how the public perceives multiple risk options, and we highlight opportunities for future research. For instance, we introduce Quick Response (QR) codes as a potential tool to help consumers view health risks in multiple formats on the Internet.</span><br></p>
