Making meaning: the creative component in qualitative research

Findings in qualitative research are often wondrous and exciting, expounding new knowledge and perceptions previously unknown. Qualitative research requires the researcher to ponder and reflect on the data collected so as to find the meaning within. Helping researchers learn how to perform this step is not well discussed in the qualitative literature, yet this is one of the more crucial components of this type of research. In this article, the incubation, the meaning-making phase of qualitative research, is discussed in relation to the experiences of five researchers who have used traditional processes, models, metaphors, plays, pastiche, poetry, and quilt making and design to help them make meaning.     

Phonological categorization of vowels: a mismatch negativity study

There is electrophysiological evidence that phonological categorization has occurred within 100-200 ms post stimulus onset for the syllables /tae/ and /dae/, which vary in voice onset time. Using a similar paradigm, this study investigated when phonological categorization occurred for the contrast between /I/ and /epsilon/, using synthesized speech tokens that differed in the frequency of the first formant. Here we show that phonological categorization of these tokens has not occurred 100-200 ms after stimulus onset. However, the presence of a late mismatch negativity (350 ms after stimulus onset) indicated that phonological categorization had taken place by this time.     

Factors influencing Queenslanders' willingness to perform bystander cardiopulmonary resuscitation

STUDY OBJECTIVE: The chances of surviving an out-of-hospital cardiac arrest (OHCA) are greatly increased if a bystander provides cardiopulmonary resuscitation (CPR) while awaiting the arrival of the emergency medical services. Over 50% of adult Queenslanders have been trained in CPR at some time in the past, however, little is known about the factors that affect their willingness to perform CPR. METHOD: A random survey of 4480 Queensland residents was conducted to address this question. RESULTS: The survey indicated that the most common barriers to performing CPR were a fear of disease, visible blood and perceived danger. In contrast, respondents indicated that they were more likely to administer CPR if the respondent knew the victim, the victim would die if CPR was not administered, and respondents believed that they possessed the necessary skills to perform CPR. A majority (84%) of respondents indicated that they were at least likely to administer CPR. A logistic regression analysis revealed that the respondents most likely to perform CPR were males, those who were married or in a de facto relationship, those in paid employment, smokers, those recently trained in CPR, prospective organ donors, those who cited no barriers to CPR and those who cited one or more factors that would facilitate CPR. CONCLUSIONS: This study indicates that there is considerable variation in Queenslanders' willingness to perform bystander CPR. Public health education campaigns aimed at correcting inaccurate perceptions of risk and addressing other barriers to bystander CPR would promote its use in response to OHCA.     

Audiometric correlates of the unaided APHAB

The Abbreviated Profile of Hearing Aid Benefit (APHAB) is a self-report questionnaire that is used to quantify the impact of a hearing problem on an individual's daily life. In this investigation, the relationships were explored between typical clinical audiometric data and the four subscale scores of the APHAB administered in the unaided (without-amplification) condition. Sixty subjects provided APHAB scores, audiograms, and speech recognition data. Analyses revealed significant relationships between audiometric data and each of the three APHAB subscales that reflect speech communication (EC, RV, and BN). None of these subscales was significantly more strongly related to any specific audiological variable. However, the pattern of associations between audiometric variables and subscale scores was consistent with predictions based on item content for subscales EC and RV, but not for BN. As predicted, no relationship was found between audiometric data and scores for the Aversiveness subscale (AV). Even for the subscales with the strongest associations, differences in audiometric data could be used to explain half or less of the variance in self-report data.     

P53 expression in spontaneous and estradiol-induced endometrial hyperplasia during menopause

OBJECTIVE: To determine the percentage of endometrial hyperplasia positive for p53 expression in both spontaneously occurring cases or following the use of unopposed estradiol. METHODS: Fifty-four postmenopausal patients with endometrial hyperplasia diagnosed by endometrial biopsy and hysteroscopy were recruited to this study. Thirty-three patients had used unopposed estradiol for periods of time from 1 to 3 years. P53 expression was detected in paraffin-embedded endometrial specimens by immunohistochemical methods. RESULTS: The percentage of endometrial hyperplasia positive for p53 expression was significantly greater in spontaneously occurring hyperplasia than in cases induced by the unopposed use of estradiol. CONCLUSION: Endometrial hyperplasia caused by the unopposed use of estradiol during menopause probably harbors fewer genomic errors than those cases occurring spontaneously.
