Seeking alcohol information on the Internet

It has been argued that people may be more willing to seek potentially threatening information on the Internet than they would in ‘real life’ (Joinson and Banyard, 2002). For alcohol drinkers, potentially threatening information includes diagnostic information on the amount they drink, and information about the negative effects of alcohol consumption. In the present study, participants with varying levels of alcohol intake and plans for change chose four alcohol-related articles to read (from twelve) using either the world-wide web (WWW) or pen and paper. Results showed that drinkers not currently reducing their drinking were more likely to seek diagnostic, potentially threatening anti-drinking information via the WWW compared to when seeking paper-based information. Drinkers either contemplating or engaging in efforts to reduce their drinking sought pro-drinking information on the WWW, and anti-drinking information when using pen and paper. The potential role of the Internet, and perceived anonymity, in health promotion is discussed

The Impact of Dual Enrollment on College Degree Attainment: Do Low-SES Students Benefit?

Dual enrollment in high school is viewed by many as one mechanism for increasing college admission and completion of low-income students. However, little evidence demonstrates that these students discretely benefit from dual enrollment and whether these programs narrow attainment gaps vis-à-vis students from middle-class or affluent family backgrounds. Using the National Education Longitudinal Study (N = 8,800), this study finds significant benefits in boosting rates of college degree attainment for low-income students while holding weaker effects for peers from more affluent backgrounds. These results remain even with analyses from newer data of college freshman of 2004. This report conducts sensitivity analyses and found that these results are robust to relatively large unobserved confounders. However, expanding dual enrollment programs would modestly reduce gaps in degree attainment

Supporting research and development in ambulance services: research for better healthcare in prehospital settings

Background This paper discusses recent developments in research support for ambulance trusts in England and Wales and how this could be designed to lead to better implementation, collaboration in and initiation of high-quality research to support a truly evidence-based service. Method The National Ambulance Research Steering Group was set up in 2007 to establish the strategic direction for involvement of regional ambulance services in developing relevant and well-designed research for improving the quality of services to patients. Results Ambulance services have been working together and with academic partners to implement research and to participate, collaborate and lead the design of research that is relevant for patients and ambulance services. Conclusion New structures to support the strategic development of ambulance and prehospital research will help address gaps in the evidence for health interventions and service delivery in prehospital and ambulance care and ensure that ambulance services can increase their capacity and capability for high-quality research

Acoustically evoked potentials in two cephalopods inferred using the auditory brainstem response (ABR) approach

It is still a matter of debate whether cephalopods can detect sound frequencies above 400 Hz. So far there is no proof for the detection of underwater sound above 400 Hz via a physiological approach. The controversy of whether cephalopods have a sound detection ability above 400 Hz was tested using the auditory brainstem response (ABR) approach, which has been successfully applied in fish, crustaceans, amphibians, reptiles and birds. Using ABR we found that auditory evoked potentials can be obtained in the frequency range 400 to 1500 Hz (Sepiotheutis lessoniana) and 400 to 1000 Hz (Octopus vulgaris), respectively. The thresholds of S. lessoniana were generally lower than those of O. vulgaris
