The demise of Bicycle George : a life of crime

This short piece looks at the life of a murderer, George Blunderfield (alias Arthur Oldring), who was hanged in Melbourne in 1918. Melburnians, or visitors to the city, may have seen his image on the wall at the Old Melbourne Gaol. Blunderfield's life started out normally
enough, and then descended into horrific crime. His story includes bicycle racing, escape from an island prison, and then recruitment for service with the Australian Imperial Forces in wartime Victoria. In the last years of his life, Blunderfield wreaked havoc from the western to the eastern coasts of Australia. This in turn had a dramatic effect on his immediate family, which is also detailed here. This story draws on the archives at PROV as well as on State Records Office of Western Australia material, with help from Ms Jean
Bellamy, a distant relative of George Blunderfield.

“Just a little bit of cheeky ribaldry”? Newsroom discourses of sexually harassing behaviour

 This paper is concerned with how Australian print news media journalists, male and female, remember, talk about, experience, acknowledge, condemn, and/or deny sexually harassing behaviour in the newsroom. A total of seventeen in-depth, semi-structured interviews were conducted with eight male and nine female journalists in late 2003 and early 2004. The interviewees ranged in age from 19 to 56 and differed in levels of industry experience. The interviews were not set up to specifically discuss sexually harassing behaviour in the newsroom; however it was a theme that arose in seven of the interviews about newsroom culture, my broader PhD project. The female interviewees make clear their encounters are constant reminders of how their bodies do not "fit" and/or where and how they do fit in this occupation. This is the case, even though some women do not use the term "sexual harassment" to describe the behaviour that clearly constitutes it under Australian government legislation. The two male journalists interviewed who mentioned harassment talk about it in defence of accepted office behaviour, or in passing about procedural business policy. The use of the term "sexual harassment," or lack of its use, also tells us about the place of feminism and/or feminist inspired government legislation in journalism's occupational culture. © 2007 Taylor & Francis.

At-sea associations in foraging little penguins

Prey distribution, patch size, and the presence of conspecifics are important factors influencing a predator's feeding tactics, including the decision to feed individually or socially. Little is known about group behaviour in seabirds as they spend most of their lives in the marine environment where it is difficult to observe their foraging activities. In this study, we report on at-sea foraging associations of little penguins (Eudyptula minor) during the breeding season. Individuals could be categorised as (1) not associating; (2) associating when departing from and/or returning to the colony; or (3) at sea when travelling, diving or performing synchronised dives. Out of 84 separate foraging tracks, 58 (69.0%) involved associations with conspecifics. Furthermore, in a total of 39 (46.4%), individuals were found to dive during association and in 32 (38.1%), individuals were found to exhibit synchronous diving. These behaviours suggest little penguins forage in groups, could synchronise their underwater movements and potentially cooperate to concentrate their small schooling prey.

Lecturing and other face-to-face teaching – too much or too little? An assessment based on student feedback and fail rates

Institutes of higher learning are tending to reduce the amount of face-to-face teaching that they offer, and particularly through the traditional pedagogical method of lecturing. There is ongoing debate about the educational value of lectures as a teaching approach, in terms of both whether they facilitate understanding of subject material and whether they augment the student educational experience. In this study, student evaluation of teaching scores plus academic outcome (percentage of students who fail) was assessed for 236 course units offered by a science faculty at an Australian university over the course of one year. These measures were related to the degree to which lectures and other face-to-face teaching were used in these units, controlling for factors such as class size, school and year level. An information-theoretic model selection approach was employed to identify the best models and predictors of student assessments and fail rates. All the top models of student feedback included a measure reflecting amount of face-to-face teaching, with the evaluation of quality of teaching being higher in units with higher proportions of lectures. However, these models explained only 12–20% of the variation in student evaluation scores, suggesting that many other factors come into play. By contrast, units with fewer lectures have lower failure rates. These results suggest that moving away from lectures and face-to-face teaching may not harm, and indeed may improve the number of students who pass the subject, but that this may be incurred at the expense of greater dissatisfaction in students' learning experience.

Interobserver Variability in the Treatment of Little Finger Metacarpal Neck Fractures

Purpose To address the null hypothesis that surgeons shown radiographs of little finger metacarpal neck fractures with measured fracture angulation would recommend surgery as often as surgeons shown unmarked radiographs. Methods Members of the Science of Variation Group, an international collaboration of fully trained orthopedic and trauma surgeons, were asked to review 20 little finger metacarpal neck fracture cases, which included a vignette and 3 high-quality radiographs. Members were then randomized to review radiographs with or without measured fracture angulation on the lateral view and select operative or nonoperative management. Results Surgeons shown radiographs with measured angulation were more likely to recommend surgery, and there was less variability among these surgeons, particularly for fractures with less angular deformity. Conclusions Measured fracture angulation has a small but significant influence on treatment recommendations for little finger metacarpal neck fractures.

Summer is a good time for informal education

Students look forward to summer because usually it means a break from formal and non-formal education. Formal education refers to education in formal educational institutions, such as pre-schools, primary, secondary and tertiary educational institutions and other registered training organisations. Non-formal education refers to organised educational activity outside the established formal system, that is intended to deliver a defined set of learning objectives to an identifiable group of learners (Chemistry in Australia, October 2014, page 33). Informal education refers to all learning outside the formal non-formal educational system; informal education is often associated with life-long learning as it can include reading non-fiction books and scholarly articles, viewing documentaries and other informal professional development. Informal education can also include travel to other countries and climates. Social constructivist theory maintains that learning occurs in social settings; conversely, most learners are limited by their cultural experiences. For example, Australian students have little first-hand experience of sublimation, but this is commonly observed in very cold climates when frost, ice or snow apparently “disappears” as it sublimes to water vapour, without passing through the liquid state. A favourite summertime activity is to go to the movies, especially in air-conditioned cinemas on a hot day or night. Watching movies are a form of virtual travel, and many educators make use of movies to illustrate chemistry concepts. Some movie producers want a sense of authenticity and work hard to get the details right, even though those details might be incidental to the main plot. For example, in Centurion, Roman soldiers fail in their rescue attempt, and are taunted by the Picts for stupidity -- they would have succeeded if they had only realised that metal become brittle in the cold. Another favourite example comes from The Lord of the Rings: The Two Towers, when Bilbo, Samwise and Gollum are crossing the Dead Marshes and see lights that appear to float over the Marshes. These wills-o-the-wisp have been known for centuries, and was the subject of a debate between George Washington and his officers. Washington and Thomas Paine, “the Father of the American Revolution”, believed that the lights were due to a flammable gas released from the marsh, while Washington’s officers believed that the lights were due to a flammable liquid on the surface of the marsh. On Guy Fawkes Night, 5 November, 1783, the Washington-Paine experiment showed that when mud at the bottom of a river was disturbed, bubbles of flammable gas rose to the surface of the water. (Unknown to Washington and Paine, Alessandro Volta had performed a similar experiment in 1776.) A problem with informal education is that it is often unguided. Students may find it difficult to discern the difference between scientific reality and an artistic distortion of reality in novels and movies. Educators have an important role here. If we only teach facts and concepts, learners will be dependent on a teacher. If however, we foster students’ curiosity and ability to exercise judgement, they will be able to learn for themselves, not just during the summer, but also in every season of every year.

Individual, school-related and family characteristics distinguish co-occurrence of drinking and depressive symptoms in very young adolescents

INTRODUCTION AND AIMS: Alcohol misuse and depressed mood are common during early adolescence, and comorbidity of these conditions in adulthood is associated with poorer health and social outcomes, yet little research has examined the co-occurrence of these problems at early adolescence. This study assessed risky and protective characteristics of pre-teens with concurrent depressed mood/early alcohol use in a large school-based sample. DESIGN AND METHODS: School children aged 10-14 years (n = 7289) from late primary and early secondary school classes in government, Catholic and independent sectors participated with parental consent in the cross-sectional Healthy Neighbourhoods Study. Key measures included depressed mood, recent alcohol use, school mobility, family relationship quality, school engagement and coping style. Multinomial logistic regression analyses were used to identify school and family-related factors that distinguished those with co-occurring drinking and depressive symptoms from those with either single condition. Gender and school-level interactions for each factor were evaluated. RESULTS: Co-occurring conditions were reported by 5.7% of students [confidence interval (CI)95 5.19, 6.19]. Recent drinkers were more likely than non-drinkers to have symptoms consistent with depression (odds ratio 1.80; CI95 1.58, 2.03). Low school commitment was associated with co-occurring drinking/depressive symptoms (odds ratio 2.86; CI95 2.25, 3.65 compared with null condition). This association appeared to be weaker in the presence of adaptive stress-coping skills (odds ratio 0.18; CI95 0.14, 0.23). CONCLUSIONS: We have identified factors that distinguish pre-teens with very early co-occurrence of drinking and depressed mood, and protective factors with potential utility for school-based prevention programmes targeting these conditions.

Influence of environmental conditions on foraging behaviour and its consequences on reproductive performance in little penguins

During the breeding season, seabirds are central place foragers and have to adapt their foraging behaviour in response to environmental variation to maximize efficiency and reproductive output. Due to its small size and swimming mode of transport, the little penguin (Eudyptula minor) is expected to be greatly susceptible to such fluctuations. The links between local-, meso- and macro-scale environmental conditions and inter-annual variation in foraging behaviour and reproductive performance of little penguins were investigated during three consecutive breeding seasons at two colonies in south-eastern Australia marked by contrasting oceanographic conditions. At a local scale, foraging effort was correlated positively with wind direction and negatively with wave height. At a regional scale, foraging effort of individuals from both colonies was negatively correlated with higher sea surface temperature (SST) off the Bonney Coast in the previous Austral summer, suggesting a weaker Bonney Upwelling event and a cascade of effects throughout the Bass Strait region. At a larger scale, the El Niño Southern Oscillation was also found to correlate with foraging behaviour, with lower foraging effort being observed during La Niña event. Although individuals increased their foraging effort during years with poorer conditions, they were not able to maintain high breeding success. In addition, peak egg-laying was found to coincide with a decrease in local SST and a peak of sea surface chlorophyll-a concentration. In conclusion, these results highlight how different environmental conditions could influence foraging behaviour and ultimately reproductive success of little penguins. It also showed that under certain circumstances, these individual strategies were not sufficient to cope with environmental variability.

The lifetime experience of traumatic events is associated with hair cortisol concentrations in community-based children

Adversity early in life can disrupt the functioning of the hypothalamic–pituitary–adrenal axis (HPAA) and increase risk for negative health outcomes. Recent research suggests that cortisol in scalp hair represents a promising of HPAA function. However, little is known about the relationship between early exposure to traumatic events and hair cortisol concentrations (HCC) in childhood, a critical period of HPAA development. The current study measured HCC in scalp hair samples collected from 70 community-based children (14 males, mean age = 9.50) participating in the Imaging Brain Development in the Childhood to Adolescence Transition Study (iCATS). Data were also collected on lifetime exposure to traumatic events and current depressive symptoms. Lifetime exposure to trauma was associated with elevated HCC; however, HCC was not associated with current depressive symptoms. Consistent with some prior work, males were found to have higher HCC than females, although results should be treated with caution due to the small number of males who took part. Our findings suggest that hair cortisol may represent a biomarker of exposure to trauma in this age group; however, further study is necessary with a particular focus on the characterization of trauma and other forms of adversity.
