Making oral presentations : some practical guidelines and suggestions

Clearly presenting research results is an important part of the research process. While research can be presented in written and oral formats, oral communication is a very effective tool for reinforcing key elements and ideas associated with a research project. Oral presentations also provide an opportunity to "sell" findings, use of multi-media and clarify issues for the audience by responding to questions. This paper focuses on oral communication and discusses issues related to "Before the Presentation", "The Presentation", and "Wrapping Up" with the aim to improve the effectiveness of presenting research results.

Oral language competence, social skills and high-risk boys : what are juvenile offenders trying to tell us?

A cross-sectional study examining the oral language abilities and social skills of male juvenile offenders is described. Fifty juvenile offenders and 50 non-offending controls completed measures of language processing and production, and measures of social skill and IQ. Information about type of offending, substance use histories and learning/literacy problems was also gathered.

Young offenders performed significantly worse on all language and social skill measures, but these differences could not be accounted for on the basis of IQ. Just over half of the young offenders were identified as language impaired. This subgroup was compared with non-language impaired offending peers on a range of variables. The findings have particular implications in the areas of early intervention for high-risk boys and investigative interviewing of juvenile offenders.

Internet-based psychological and oral medical treatment compared to psychological treatment alone for ED

Introduction. Sexual function through pregnancy and the postpartum period is an important aspect of quality of life.
Despite this, prospective studies are limited, and the impact of body image on sexual function has not been explored.
Aims. The current study reports on a pilot study that evaluated the effectiveness of a combined Internet-based
psychological treatment program and oral medication compared to an Internet-based psychological program.
Methods. Twelve men with ED participated in the study.
Main Outcome Measures. Assessments were made pre and postintervention on ED, relationship satisfaction, sexual
satisfaction, self-esteem, and quality of life.
Results. Multivariate analyses of variance demonstrated that both treatment conditions showed improvements from
pretest to posttest in sexual functioning, relationships, and personal well-being.
Conclusions. This study indicates the importance of targeting psychological and relationship variables in the
treatment of ED. Further research with larger numbers of participants is necessary for a more rigorous evaluation
of treatment programs that combine psychological and medication interventions for ED.

Securing the oral tradition : reflective positioning and professional conversations in midwifery education

We postulate that positioning is a powerful tool in guiding and transforming student professional learning and practice development. In our experiences with students enrolled in he Graduate Diploma of Midwifery, we determined that positioning elaborates individual scholarship and identity formation of the learner midwife in practice settings. Positioning Theory, developed by Harré and other authorities, is a psycho-sociological 'ontology' or concept of how individuals metaphorically position or locate themselves, and others, within institutions and societies. Three key components of positioning theory include 'position', 'speech act' and 'storylines', developing from the everyday social interactions of professional conversations. Reflective positioning can be applied as an analytical tool for the moment-to- moment exchanges inherent in practice related conversations, occurring between midwives and midwifery students. These moment-to-moment interactions of professional conversations can be used by students to complete or fill their learning gaps. Positioning therefore, provides a novel, contemporary theoretical framework to 'unpack' or understand the complexity of midwifery practice and yet is complementary with reflective practice. Excerpts are used to demonstrate reflective positioning applications by students. Midwives are encouraged by health services and by the University to provide student support through a 'preceptorship' program to supervise, work with and assess students for competence in midwifery practices. We claim that reflective positioning by students within professional conversations with their preceptor/midwives, are the construction sites for learning and where identity formation of each student as a future midwife is both shaped and transformed. Both academics and managers of health services need to embrace the value of workplace conversations, the sites of rich oral traditions of nursing and midwifery. Thus, in seeking claim to our rich oral traditions, all students will benefit from engagement in reflective positioning to promote their professional learning and practice development.

Quality of life related to oral versus subcutaneous iron chelation: a time trade-off study

Objective: To investigate the utility associated with subcutaneous infusion (deferoxamine) compared with once-daily oral administration (deferasirox) of iron chelation therapy.

Methods: Interviews using the time trade-off technique were used to estimate preferences (utility) for health states by finding the point at which respondents were indifferent between a longer but lower quality of life (QoL) and a shorter time in full health. Participants (n = 110) were community-based, 51% women, median age 35 years, from four regions in Sydney, Australia. Respondents rated three health states involving equal outcomes for people with thalassemia but with different treatment modalities for iron chelation; an "anchor state" describing a patient receiving iron chelation without administration mode specified, anchor state plus iron chelation via subcutaneous infusion, and anchor state plus iron chelation through once-daily oral medication.

Results: On an interval scale between 0 (death) and 1 (full health), median (interquartile range) utility of 0.80 (0.65–0.95) for the anchor state, 0.66 (0.45–0.87) for subcutaneous infusion, and 0.93 (0.80–0.97) for once-daily oral administration was obtained. The mean (median) difference of 0.23 (0.27) between the two treatments was statistically significant (Wilcoxon-signed rank test, P < 0.001). Subcutaneous infusion was associated with a mean (median) utility 0.13 (0.14) lower than the anchor state (P < 0.001), and once-daily oral treatment had a utility 0.10 (0.13) higher (P < 0.001).

Conclusion: Community respondents associate oral administration of an iron chelator such as deferasirox with enhanced QoL compared with subcutaneous treatment. Assuming equal safety and efficacy, QoL gains from once-daily oral treatment compared with subcutaneous infusion are significant.

Differences in height explain gender differences in the response to the oral glucose tolerance test - the AusDiab study

Aim To determine the extent of gender-related differences in the prevalence of glucose intolerance for the Australian population and whether body size may explain such differences.

Methods Cross-sectional data were collected from a national cohort of 11 247 Australians aged ≥ 25 years. Glucose tolerance status was assessed according to both fasting plasma glucose (FPG) and 2-h plasma glucose (2hPG) levels following a 75-g oral glucose tolerance test (OGTT). Anthropometric and glycated haemoglobin measurements were also made.

Results Undiagnosed diabetes and non-diabetic glucose abnormalities were more prevalent among men than women when based only on the FPG results (diabetes: men 2.2%, women 1.6%, P = 0.02; impaired fasting glycaemia: men 12.3%, women 6.6%, P < 0.001). In contrast 16.0% of women and 13.0% of men had a 2hPG abnormality (either diabetes or impaired glucose tolerance, P = 0.14). Women had a mean FPG 0.3 mmol/l lower than men (P < 0.001), but 2hPG 0.3 mmol/l higher (P = 0.002) and FPG-2hPG increment 0.5 mmol/l greater (P < 0.001). The gender difference in mean 2hPG and FPG-2hPG increment disappeared following adjustment for height. For both genders, those in the shortest height quartile had 2hPG levels 0.5 mmol/l higher than the tallest quartile, but height showed almost no relationship with the FPG.

Conclusions Men and women had different glycaemic profiles; women had higher mean 2hPG levels, despite lower fasting levels. It appeared that the higher 2hPG levels for women related to lesser height and may be a consequence of using a fixed glucose load in the OGTT, irrespective of body size.
