Factors Facilitating and Inhibiting the Use of Research to Inform Interpretation Practice: A Case Study of Australian Protected Area Management Agencies

ABSTRACT

Interpretation research can be and is used to inform and improve interpretation policymaking and planning undertaken by practitioners such as those who work for Australian protected area management (PAM) agencies. This study explores perceptions of the extent to which interpretation research is undertaken and used by these agencies, and the facilitators and constraints to doing so. In-depth telephone interviews were conducted with senior interpretation planners and managers in all Australian PAM agencies. The findings indicate that interpretation research is usually prompted by a crisis or a short-term need such as a specific project and that most research is site-specific and content-focused, while respondents see a need for more longitudinal and evaluation-focused research. Two-thirds of the respondents reported that their agency made poor or no use of research findings for improving interpretation practice. Stated barriers to undertaking and using research included lack of funding, lack of time and that research was not considered an agency priority. Underpinning these were perceptions consistent with diffusion of innovation theory (e.g., that doing or using research is perceived as being too complex, not compatible with agency goals or not offering relative advantage). Strategies for removing these perceptual barriers to undertaking and using interpretation research and research findings are presented.     

Recurrence of Posttraumatic Stress Disorder in Late Life: A Cognitive Aging Perspective

Clinical experience with older adults shows that many will experience PTSD symptoms in older adulthood because of trauma exposure early in life. Some of these patients struggled with PTSD in the distant past and remained symptomfree for decades only to have a recurrence of PTSD in late life. This paper outlines a cognitive aging explanation for the recurrence of PTSD. It is proposed that the age-related decreases in attention make the intrusion of trauma-related memories more likely. The increase in intrusive memories, combined with age-related decreases in working memory, explicit memory, and prospective memory, increases the subjective distress associated with the memories and results in a recurrence of PTSD.     

Delayed sidetone in relation to the reading of different materials

Several studies were conducted with speakers reading short phrases aloud while experiencing one amount or another of delayed sidetone (0.0–0.30 sec). The phrases represented different numbers of syllables, different types of syllables, different numbers of phonemes, and first and second languages. Additional syllables and unfamiliar material consistently increased the reading time of the speakers disproportionately. The reading of syllables of two and four sounds was apparently more retarded by delayed sidetone than ones of three sounds. Two-sound syllables comprised of vowel-consonants required more time to read than ones comprised of consonant-vowels. The effect of additional phonemes, with the type of syllables held constant, added linearly in the reading time of the phrases. The syllabic characteristics, the length, and probably the familiarity of the material affected the reading time nonlinearly.
