Bullying among Australian school children: reported behavior and attitudes toward victims.

Abstract: The extent of bullying among Australian school children and attitudes toward victims of bullying were investigated in a survey of Australian school children between the ages of 6 and 16 years (n = 685) and their teachers (n = 32). Approximately 1 child in 10 was subjected to peer group bullying. Boys reported being bullied more often than girls, who tended to be more supportive of victims. With increasing age, there was a slight but significant decline in reported bullying; notably, however, attitudes toward victims became less supportive. Attitudes toward victims were examined in detail by using a reliable and validated 20-item Likert scale. Factor analyses of the children's responses yielded three interpretable factors: a tendency to despise the victims of bullies; general admiration for school bullies; and avowed support for intervention to assist the victim. An understanding of such attitudes is desirable for designing effective intervention programs.

The benefits of noise in neural systems: bridging theory and experiment

Abstract: Although typically assumed to degrade performance, random fluctuations, or noise, can sometimes improve information processing in non-linear systems One such form of 'stochastic facilitation', stochastic resonance, has been observed to enhance processing both in theoretical models of neural systems and in experimental neuroscience However, the two approaches have yet to be fully reconciled Understanding the diverse roles of noise in neural computation will require the design of experiments based on new theory and models, into which biologically appropriate experimental detail feeds back at various levels of abstraction

The sixth visual object tracking VOT2018 challenge results

Abstract: The Visual Object Tracking challenge VOT2018 is the sixth annual tracker benchmarking activity organized by the VOT initiative. Results of over eighty trackers are presented; many are state-of-the-art trackers published at major computer vision conferences or in journals in the recent years. The evaluation included the standard VOT and other popular methodologies for short-term tracking analysis and a “real-time” experiment simulating a situation where a tracker processes images as if provided by a continuously running sensor. A long-term tracking subchallenge has been introduced to the set of standard VOT sub-challenges. The new subchallenge focuses on long-term tracking properties, namely coping with target disappearance and reappearance. A new dataset has been compiled and a performance evaluation methodology that focuses on long-term tracking capabilities has been adopted. The VOT toolkit has been updated to support both standard short-term and the new long-term tracking subchallenges. Performance of the tested trackers typically by far exceeds standard baselines. The source code for most of the trackers is publicly available from the VOT page. The dataset, the evaluation kit and the results are publicly available at the challenge website (http://votchallenge.net).

Lessons Learned from the Maroochy Water Breach

Abstract: Supervisory control and data acquisition (SCADA) systems are widely used to monitor and control operations in electrical power distribution facilities, oil and gas pipelines, water distribution systems and sewage treatment plants. Technological advances over the past decade have seen these traditionally closed systems become open and Internet-connected, which puts the service infrastructures at risk. This paper examines the response to the 2000 SCADA security incident at Maroochy Water Services in Queensland, Australia. The lessons learned from this incident are useful for establishing academic and industry-based research agendas in SCADA security as well as for safeguarding critical infrastructure
