Trends in the Research and Practice of Health Communication Campaigns

A compelling communication tool that can potentially impact health‐related outcomes and indicators across numerous health problems among a diversity of audiences is the health communication campaign. The purpose of the current article is to discuss trends in the research and practice of health communication campaigns. First, we discuss the issue of campaign effects and discuss a framework that encompasses key principles of effective campaigns. Next, we discuss four trends in health communication campaigns: (a) the increased application of marketing principles in campaigns; (b) the greater use of rigorous outcome evaluation designs in campaign research; (c) the increased use of cost effectiveness analysis in campaigns; and (d) the increased use of new media technologies in campaigns. Finally, we conclude the article with thoughts about the future of health communication campaign research and practice in relation to these trends.     

Instant Ticket Purchasing by Ontario Baby Boomers: Increasing Risk for Problem Gamblers

Instant ticket purchase gambling (ITPG) is pervasive in Ontario and has features that mimic slot machine play. Previous researchers have reported that ITPG is one preferred activity for at-risk/problem gamblers. In the general Canadian population, rate of participation in ITPG is second only to lottery ticket gambling. Both are particularly favored by youth and seniors. The next cohort of seniors will be Canada’s baby boomers, one-third of whom live in Ontario. Secondary analysis of Statistics Canada data revealed that adults in this cohort who buy instant gambling tickets (N = 1781) are significantly different from the complete group of their age peers (N = 4266) in number of activities pursued and frequency of involvement. At-risk/problem gambling prevalence was 10.2% amongst Ontario baby boomers who participate in instant ticket gambling, significantly higher than the 6.7% found amongst the total group of baby boom gamblers. For those who reported experiencing one or more of the Canadian Problem Gambling Index indicators for problem gambling (N = 237), 73% were buying instant tickets. Future research should consider cohort effects and explore combinations of preferred gambling activities that may increase risk for problem gambling. Social policy recommendations include the use of all ITPG venues as key locations for promoting awareness of problem gambling treatment services. This work was funded by Ontario Problem Gambling Research Centre.     

Evidencing the harms of hate speech

The ways in which targeted communities experience hate speech is an important, but often neglected, component of the debate over the legitimacy of hate speech laws. This article reports on data drawn from interviews conducted with 101 members of Indigenous and minority ethnic communities in Australia regarding their experiences of hate speech. We give voice to targets’ experiences of face-to-face and more widely broadcast hate speech, and outline the constitutive and consequential harms they claim to have suffered. We assess these against the alleged harms of hate speech in the literature, finding a close correlation between targets’ reports and the literature.     

Using innovation to address HIV, AIDS, and environment links: intervention case studies from Zimbabwe, Uganda, and Malawi

This article presents three cross-cutting intervention case studies that address HIV, AIDS, and natural resources management in an integrated manner through innovative programming in Zimbabwe, Uganda, and Malawi. In Zimbabwe, a religious-based non-governmental group and two community organizations work together to build skills of HIV- and AIDS-vulnerable children in rural areas to meet dietary and income needs, while using natural resources sustainably. In Uganda, various government agencies and NGO actors work together to improve the food security of HIV-affected households at the national, district, sub-district, and village levels. Finally, in Malawi, a conservation organization incorporates HIV and AIDS awareness and programming into its operations and projects. Each case study presents pioneering approaches to simultaneously addressing the pressures on conservation initiatives, food security/agricultural production, income generation/livelihoods, and social and health care systems. They also provide lessons for expanding interventions and partnerships.     

Visual assessment of matrix-variate normality

In recent years, the analysis of three-way data has become ever more prevalent in the literature. It is becoming increasingly common to analyse such data by means of matrix-variate distributions, the most prevalent of which is the matrix-variate normal distribution. Although many methods exist for assessing multivariate normality, there is a relative paucity of approaches for assessing matrix-variate normality. Herein, a new visual method is proposed for assessing matrix-variate normality by means of a distance–distance plot. In addition, a testing procedure is discussed to be used in tandem with the proposed visual method. The proposed approach is illustrated via simulated data as well as an application on analysing handwritten digits.     

Statistical word segmentation: Anchoring learning across contexts

The present experiments were designed to assess infants' abilities to use syllable co-occurrence regularities to segment fluent speech across contexts. Specifically, we investigated whether 9-month-old infants could use statistical regularities in one speech context to support speech segmentation in a second context. Contexts were defined by different word sets representing contextual differences that might occur across conversations or utterances. This mimics the integration of information across multiple interactions within a single language, which is critical for language acquisition. In particular, we performed two experiments to assess whether a statistically segmented word could be used to anchor segmentation in a second, more challenging context, namely speech with variable word lengths. The results of Experiment 1 were consistent with past work suggesting that statistical learning may be hindered by speech with word-length variability, which is inherent to infants' natural speech environments. In Experiment 2, we found that infants could use a previously statistically segmented word to support word segmentation in a novel, challenging context. We also present findings suggesting that this ability was associated with infants' early word knowledge but not their performance on a cognitive development assessment.     

Air Nicotine and Saliva Cotinine as Indicators of Workplace Passive Smoking Exposure and Risk1

We model nicotine from environmental tobacco smoke (ETS) in office air and salivary cotinine in nonsmoking U.S. workers. We estimate that: an average salivary cotinine level of 0.4 ng/ml corresponds to an increased lifetime mortality risk of 1/1000 for lung cancer, and 1/100 for heart disease; >95% of ETS-exposed office workers exceed OSHA's significant risk level for heart disease mortality, and 60% exceed significant risk for lung cancer mortality; 4000 heart disease deaths and 400 lung cancer deaths occur annually among office workers from passive smoking in the workplace, at the current 28% prevalence of unrestricted smoking in the office workplace.
