Filching the Argentine colonists : the encouragement of Patagonians to the Northern Territory in the early twentieth century

This paper explores the background to the emigration of 220 settlers from Patagonia in South America to the Northern Territory during the course of World War I. The group, which arrived in Darwin on the Kwanto Maru in 1915, comprised an unusual mixture of nationalities. The breakdown given in the passenger list and the contemporary press was 113 Spaniards, 45 Russians, 30 Italians. 28 British, I Argentinian [of British parents], 1 Frenchman, 1 Serbian and 1 Greek. Some of the 'Spaniards' were presumably Spanish speaking Argentinians but most were indeed of Spanish descent, such as the Martinez, Perez and Villalba families. Of the British amongst the group, almost all were Welsh. They came as a result of inducements held out to the Welsh amongst the party in the years immediately prior to the war by the Commonwealth Government, which administered the Northern Territory after 1911. This account provides a fascinating case study of the recruitment of immigrants to Australia, and particularly to the Northern Territory, in the early twentieth century.

On-screen supervision relationships versus face-to-face

Videoconferencing provides access to essential training for probationary psychologists in rural areas. However the unique aspects of videoconferenced communication (Jerome & Zaylor, 2000) challenge an assumed equivalency of face-to-face and videoconferenced interactions. This study investigated the relevance of power, involvement, and an established model of supervision (Bernard, 1979, 1997) to the working relationship in videoconferenced supervision. Semistructured interviews were conducted with four supervisors, eighteen trainees experienced in videoconferenced supervision and four trainees experienced in face-to-face supervision. Data were analysed by qualitative content analysis, coding pertinent theoretical constructs. Results confirmed that the roles defined by Bernard's supervision model (teacher, counsellor and consultant) were relevant to videoconferenced supervision. However a further role emerged as well. Power and involvement dimensions also had relevance for videoconferenced interactions with some suggestion that the power discrepancy between trainee and supervisor was increased. Complexities arising from videoconferencing included some trainees avoiding involvement by blaming technical malfunctions, some reporting curtailed emotional expression and others reporting freer emotional expression due to the distal nature of the medium. The findings affirm some unique features to videoconferenced supervision and validate a framework to further explore the impact of videoconferencing upon supervisory relationships.

Training general practitioners in flexible sigmoidoscopy to screen for colorectal cancer

Background: A screening programme to detect polyps or early carcinoma would significantly reduce the mortality and morbidity of colorectal cancer (CRC). The aims of the present study were to evaluate: (i) the feasibility of training general practitioners in flexible sigmoidoscopy (FS) for CRC screening; (ii) the acceptability of screening by faecal occult blood testing (FOBT) and FS in asymptomatic standard risk Australians aged over 50 years; and (iii) the yield of such screening. Methods: Subjects were recruited by general practitioner (GP) referral, newspaper advertisement or by a direct approach to retirement villages. Participants were mailed a FOBT kit and a prescreening questionnaire. Flexible sigmoidoscopy was performed by a GP supervised by an experienced endoscopist. Subjects then completed a second questionnaire. General practitioners were assessed after 50 unassisted procedures. Results: A total of 264 individuals contacted the study coordinator; 169 were screened. Screening was accepted well by the participants. Fifteen per cent of subjects had polyps and 4% had a positive FOBT. Training in FS was adversely affected by the availability of resources. Three GPs completed 50 unassisted procedures over a 15-month period, but none were able to reliably assess the distal bowel. Conclusions: Although the three trainees and their supervisors did not consider that the GPs were adequately trained after 50 unassisted procedures, training was adversely affected by limited resources within the Victorian public hospital system. Screening by FOBT and FS was considered to be acceptable by the patients undergoing these procedures. Existing facilities are not adequate if GPs are to be trained in FS as part of a national CRC screening program.

(falling into) the space between the screen and the audience

The following is from a presentation at the Double Dialogues Conference, On Space, at The University of Otago, Dunedin, June 3, 2006.There is a space between things, and between things there is a space – a gap. This presentation considers the gap – that space in the cinema – between the audience and the screen. I am referring to the Cinema as an institution, and the cinema as a location. It is a space where films are screened: (often) with a screen, a projector facing the screen and an audience hovering between.

Outcomes of a group-randomized trial to prevent excess weight gain, reduce screen behaviours and promote physical activity in 10-year-old children : switch-play

Objectives : To evaluate the effectiveness of an intervention to prevent excess weight gain, reduce time spent in screen behaviours, promote participation in and enjoyment of physical activity (PA), and improve fundamental movement skills among children.

Participants : In 2002, 311 children (78% response; 49% boys), average age 10 years 8 months, were recruited from three government schools in low socioeconomic areas of Melbourne, Australia.

Design : Group-randomized controlled trial. Children were randomized by class to one of the four conditions: a behavioural modification group (BM; n=66); a fundamental movement skills group (FMS; n=74); a combined BM/FMS group (BM/FMS; n=93); and a control (usual curriculum) group (n=62). Data were collected at baseline, post intervention, 6- and 12-month follow-up periods.

Results : BMI data were available for 295 children at baseline and 268 at 12-month follow-up. After adjusting for food intake and PA, there was a significant intervention effect from baseline to post intervention on age- and sex-adjusted BMI in the BM/FMS group compared with controls (-1.88 kg m-2, P<0.01), which was maintained at 6- and 12-month follow-up periods (-1.53 kg m-2, P<0.05). Children in the BM/FMS group were less likely than controls to be overweight/obese between baseline and post intervention (adjusted odds ratio (AOR)=0.36, P<0.05); also maintained at 12-month follow-up (AOR=0.38, P<0.05). Compared with controls, FMS group children recorded higher levels and greater enjoyment of PA; and BM children recorded higher levels of PA and TV viewing across all four time points. Gender moderated the intervention effects for participation in and enjoyment of PA, and fundamental movement skills.

Conclusion : This programme represents a promising approach to preventing excess weight gain and promoting participation in and enjoyment of PA. Examination of the mediators of this intervention and further tailoring of the programme to suit both genders is required.

Dose-response associations between screen time and overweight among youth

Objective. To examine dose-response associations between screen time and overweight, independent of physical activity and dietary intake.

Methods. Participants were 580 Dutch youth (13 years; 48% boys). Body mass index, waist circumference and skinfold thickness at four sites determined weight status. Questionnaires examined television viewing and computer use, participation in organized sport and high caloric snack and sugar-containing beverage consumption.

Results. There were no significant associations among boys. Compared with girls spending less than two hours/day in screen time, those who spent three to four hours/day were more likely to be classified as overweight by waist circumference (odds ratio [OR]=3.4; 95% confidence intervals [CI]=1.1-10.7; p=0.03), and this likelihood increased substantially among those spending more than four hours/day (OR=5.5; 95% CI=2.1-14.1; p≤0.0001).

Conclusions. Girls who spend three or more hours/day in screen time are at increased risk of being classified as overweight by waist circumference.

Floor trading and screen trading : distinctions for practitioners

The creation of an electronic limit order book is discussed as the basis for distinguishing between the floor trading and screen trading of derivative instruments. Distinguishing between FTP and ETP in terms of market transparency allows investors to contemplate the trade-off between the 2 platforms. Distinguishing between FTP and ETP in terms of memory preservation allows practitioners to contemplate the different experiences when analyzing floor data and screen data. A comparable set of floor and screen data is used to examine the impact on the trading dynamics and price discovery of LIFFE's FTSE 100 index futures market when trading is automated on LIFFE CONNECT. The dynamics in the quote change equation is shortened when moving from the floor to screen sample. Using the model's measure of trade informativeness, it is found that in 4 out of 5 daily sub-samples, screen trades are more than twice as informative as floor trades. Variability within a system of equations is explained more by order size history than trade size history.

Paramedic identification of stroke : community validation of the Melbourne ambulance stroke screen

Background: Paramedics require an effective prehospital tool to eliminate stroke mimics and to assist in the identification of suitable candidates for thrombolytic therapy. The Faster Access to Stroke Therapies study combined two validated stroke assessment tools (the Los Angeles Prehospital Stroke Screen, LAPSS, and the Cincinnati Prehospital Stroke Scale, CPSS) to form the Melbourne Ambulance Stroke Screen (MASS), and performed an in-field validation by Australian paramedics.

Methods: Over a 12-month period, 18 paramedics participated in the Faster Access to Stroke Therapies study and prospectively collected data contained in the MASS on all stroke dispatches, and for other patients with a focal neurological deficit. Sensitivity and specificity analysis of the LAPSS, CPSS and MASS was calculated and equivalence analysis performed.

Results: Paramedics completed 100 MASS assessments for 73 (73%) stroke/transient ischemic attack patients and 27 (27%) stroke mimics. The sensitivity of the MASS (90%, 95% CI: 81-96%) showed statistical equivalence to the sensitivity of the CPSS (95%, p = 0.45) and superiority to the LAPSS (78%, p = 0.008). The specificity of the MASS (74%, 95% CI: 53-88%) was equivalent to that of the LAPSS (85%, p = 0.25) and superior to the CPSS (54%, p = 0.007). All patients misidentified by the MASS (7 strokes, 7 mimics) were ineligible for thrombolytic therapy.

Conclusion: The MASS is simple to use, with accurate prehospital identification of stroke. It distinguishes stroke mimics, with good recognition of suitable patients for thrombolytic therapy.

A new screen face for public service broadcasting

The contemporary broadcasting industry is characterised by technological and social change, it is increasingly competitive, and the media industry is fragmenting. New services need not necessarily compete with existing free-to-air broadcasting but could act as further incentive for audiences to invest in new equipment. New equipment will be necessary in the future as set out under the Television Broadcasting Services (Digital Conversion) Act 2000 (Cth), before the planned switch-off of analogue broadcasts planned for this year but now likely to be 2013. By then, however, audiences might already have migrated to the online environment for television and radio content as well as other services. Those that produce and deliver programs via free-to-air broadcasting need to consider what audiences do with new media in order to engage them. This will be an ongoing process as technology and audience expectations continue to change. Against such a background, this article examines how Australia’s public broadcasters are responding to the new media environment. It will consider their interactive online programs and services with specific analysis of ABC’s new ‘iView’ and ‘ABC Fora’ which offer content on-demand. It will also examine SBS online initiatives. I wish to argue that the new media offer public broadcasters new prospects to provide forums and spaces for education, entertainment, public discussion and interaction online.
