Promoting gun trigger-lock use: insights and implications from a radio-based health communication intervention

A radio public service announcement (PSA) focusing on the danger to children from an unlocked and loaded gun was designed and aired 340 times on three radio stations in one Michigan county. At the end of the message, individuals were given a toll-free number to call to receive a free gun trigger-lock. Three surveys were used to assess the effectiveness of this intervention: a general population telephone survey, an automated telephone survey, and a follow-up mail survey. Approximately 20 percent of individuals in the general population heard the PSA. There was a significant increase in uncued knowledge of the locking-related gun-safety practices in the treatment county between time one and time two. Further, individuals in both counties had very high levels of self-efficacy and response efficacy, moderate levels of perceived severity, and very low levels of perceived susceptibility at both points in time. Seven-hundred and ninety-nine individuals called the toll-free number to receive a free gun trigger-lock; or approximately 17 percent of gun-owning households exposed to the message. The majority of callers were males who owned guns primarily for hunting purposes and who planned to use the lock themselves. Follow-up survey results indicated that individuals were using the gun trigger-locks, and that they believed using gun trigger-locks was an easy and effective way to prevent gun injuries. Insights and practical implications of these findings are discussed.     

The wicked problem of embedding academic literacies: exploring rhizomatic ways of working through an adaptive leadership approach

Embedding academic literacies in higher education courses has been a major focus of the work of learning advisers. A number of studies present the results of embedding in specific courses without discussing the processes of negotiation or the different people involved. This paper is about embedding academic literacies in the Business faculty as part of an English language proficiency model at an Australian university. After initial slow progress, a team of learning advisers began to evaluate the process by reflecting on practice. This reflection focused on the space between the top-down process as planned and what actually happened in the complex academic environment. There were tensions between the proposed plan and the expectations and understandings of the disciplinary academics. These were used as a starting point to explore the issues in more detail. This paper argues that the task of embedding academic literacies bears all the hallmarks of a ‘wicked problem’ which eludes a linear formulation and is open to multiple framings. The botanical metaphor of the rhizome from the philosophy of Deleuze and Guattari and an adaptive leadership approach offer ways of responding to this problem. This paper reinterprets the team’s experiences using these theories and suggests alternative work practices. By moving away from the concept of a model, more opportunities to bring about attitudinal and curriculum change can be created to make academic literacies explicit for students.     

Enhancing Memory Access for Less Skilled Readers

Less skilled readers’ comprehension often suffers because they have an impoverished representation of text in long-term memory; this, in turn, increases the difficulty of gaining access to backgrounded information necessary for maintaining coherence. The results of four experiments demonstrated that providing less skilled readers with additional explicit interconnections enhanced their text representations in memory and increased their ability to maintain coherence. Experiments 1a and 1b confirmed the finding that less skilled readers were not disrupted by global inconsistencies. Experiments 2a and 2b showed that text manipulations designed to enhance the accessibility of global information led to less skilled readers being disrupted by global inconsistencies.
