Using a peer action learning approach in the implementation of communication and information technology in social work education

This paper reports on a peer group learning process developed within a School of Social Work to facilitate the implementation of intra-net sites to support all modules provided on a Masters Diploma in Social Work course. Based on principles of action learning, an exposition of the approach taken illuminates the value of using collective peer learning among a team of educators, especially when implementing teaching and learning methodologies which are relatively new and unfamiliar. Within the context of this demonstration, the importance of ongoing critical reflection about the use of C&IT resources to enhance learning and teaching is highlighted. The paper ends with a commentary on how learning from this process has enabled participants to become more advanced users of C&IT--advanced, not just in terms of the technical competence required to provide C&IT resources but also in terms of their ability to reflect critically on the pedagogical concerns. Possibilities for continuation and transferability of the learning process within social work education are considered.     

The self-prescribed use of aromatherapy oils by pregnant women

BackgroundWhile some studies have reported effectiveness of aromatherapy oils use during labour there is no reported evidence of efficacy or risks of aromatherapy oils use for pregnancy-related symptoms or conditions. A number of aromatherapy oils are unsafe for use by pregnant women yet there is currently no research examining the prevalence and characteristics of women who use aromatherapy oils during pregnancy.AimTo conduct an empirical study of the prevalence and characteristics of women who use aromatherapy oils during pregnancy.MethodsThe research was conducted as part of the Australian Longitudinal Study on Women's Health (ALSWH), focusing on the nationally representative sample of Australian women aged 31–36 years. Data were collected via a cross-sectional questionnaire (n = 8200) conducted in 2009.ResultsSelf-prescribed aromatherapy oils were used by 15.2% of pregnant women. Pregnant women were 1.57 (95% CI: 1.01, 2.43) times more likely to self-prescribe use of aromatherapy oils if they have allergies or hayfever, and 2.26 (95% CI: 1.34, 3.79) times more likely to self-prescribe use of aromatherapy oils if they have a urinary tract infection (UTI).ConclusionOur study highlights a considerable use of aromatherapy oils by pregnant women. There is a clear need for greater communication between practitioners and patients regarding the use of aromatherapy oils during pregnancy, as well a need for health care practitioners to be mindful that pregnant women in their care may be using aromatherapy oils, some of which may be unsafe.     

Probing infants’ sensitivity to pupil size when viewing eyes

Sensitive responding to eye cues plays a key role in human social interactions. Pupil size provides subtle cues regarding a social interaction partner's arousal states. The current study assessed infants’ sensitivity to and preference for differences in pupil size. Specifically, we examined White 14-month-old infants’ pupillary responses when viewing own-race and other-race (Asian) eyes with dilating, constricting, and static medium-sized pupils. Our results show that, independent of race, infants’ pupils dilated more when viewing eyes with dynamically changing (dilating and constricting) pupils than when viewing eyes with non-changing, static, and medium-sized pupils. We also measured infants’ looking preferences, showing that, independent of race, infants preferentially attended to eyes with dilated pupils. Moreover, our results show that infants orient more quickly to pupillary changes in own-race eyes than in other-race eyes. These findings demonstrate that infants detect, but do not mimic, changes in pupil size in others and show a preference for eyes with dilated pupils.     

Estimating Probability Distributions by Observing Betting Practices

A bookmaker takes bets on a two-horse race, attempting to minimize expected loss over all possible outcomes of the race. Profits are controlled by manipulation of customer' betting behavior; in order to do this, we need some information about the probability distribution which describes how the customers will bet. We examine what information initial customer' betting behavior provides about this probability distribution, and consider how to use this to estimate the probability distribution for remaining customers.     

Marginal Correlation in Longitudinal Binary Data Based on Generalized Linear Mixed Models

This work aims at investigating marginal correlation within and between longitudinal data sequences. Useful and intuitive approximate expressions are derived based on generalized linear mixed models. Data from four double-blind randomized clinical trials are used to estimate the intra-class coefficient of reliability for a binary response. Additionally, the correlation between such a binary response and a continuous response is derived to evaluate the criterion validity of the binary response variable and the established continuous response variable.     

Neighborhood history as a factor shaping syringe distribution networks among drug users at a U.S. syringe exchange

Throughout the U.S., high visibility drug markets are concentrated in neighborhoods with few economic opportunities, while drug buyers/users are widely dispersed. A study of Pittsburgh Syringe Exchange participants provides data on travel between and network linkages across neighborhoods with different levels of drug activity. There are distinct racial patterns to syringe distribution activity within networks and across neighborhoods. Pittsburgh's history suggests that these patterns emerge from historical patterns of social and economic development. Study data demonstrate the ability of IDUs to form long-term social ties across racial and geographic boundaries and use them to reduce the risk of HIV transmission.     

Social Support from Parents,Friends, Classmates,and Teachers in Children and Adolescents Aged 9 to 18 Years: Who Is Perceived as Most Supportive?

Age and gender differences in perceived social support from parents, friends, classmates, and teachers were investigated in 304 boys and 351 girls aged 9–18 years. The social support scale for children and adolescents was used for this purpose. Analyses showed that the level of perceived social support from parents and friends was similar across age groups. The study of the prominence of social support sources showed that parents and friends were perceived as equally supportive; only for the ages 16–18 years did friend support exceed parent support. Support from teachers was lower in the older age groups, and this was related to the transition from primary to secondary school. Finally, girls perceived more support from teachers, classmates and friends than boys did.
