‘Let’s get sexting’: risk, power, sex and criminalisation in the moral domain

This article explores the criminalisation and governance of sexting among young people.While the focus is on Australian jurisdictions, the article places debates and anxieties about sexting and young people in a broader analysis around concerns about new technologies, child sexual abuse, and the risks associated with childhood sexuality. The article argues that these broader social, cultural and moral anxieties have created an environment where rational debate and policy making around teen sexting has been rendered almost impossible. Not only has the voice of young people themselves been silenced in the public, political and media discourse about sexting, but any understanding about the differing behaviours and subsequent harms that constitute teen sexting has been lost. All the while, sexting has been rendered a pleasurable if somewhat risky pastime in an adult cultural context lending weight to the argument that teen sexting is often a subterranean expression of activities that are broadly accepted.The article concludes that the current approaches to regulating teen sexting, along with the emergence of sexting as a legitimate adult activity, may have had the perverse consequence of making teen sexting an even more attractive teenage risk taking activity.Authored by Murray Lee, Thomas Crofts, Michael Salter, Sanja Milivojevic and Alyce McGovern

Experiences and issues for environmental science sensor network deployments

Sensor network research is a large and growing area of academic effort, examining technological and deployment issues in the area of environmental monitoring. These technologies are used by environmental engineers and scientists to monitor a multiplicity of environments and services, and, specific to this paper, energy and water supplied to the built environment. Although the technology is developed by Computer Science specialists, the use and deployment is traditionally performed by environmental engineers. This paper examines deployment from the perspectives of environmental engineers and scientists and asks what computer scientists can do to improve the process. The paper uses a case study to demonstrate the agile operation of WSNs within the Cloud Computing infrastructure, and thus the demand-driven, collaboration-intense paradigm of Digital Ecosystems in Complex Environments

Extending sensor networks into the cloud using Amazon web services

Sensor networks provide a method of collecting environmental data for use in a variety of distributed applications. However, to date, limited support has been provided for the development of integrated environmental monitoring and modeling applications. Specifically, environmental dynamism makes it difficult to provide computational resources that are sufficient to deal with changing environmental conditions. This paper argues that the Cloud Computing model is a good fit with the dynamic computational requirements of environmental monitoring and modeling. We demonstrate that Amazon EC2 can meet the dynamic computational needs of environmental applications. We also demonstrate that EC2 can be integrated with existing sensor network technologies to offer an end-to-end environmental monitoring and modeling solution

Polarization Structures in the Thomson-Scattered Emission Lines in Active Galactic Nuclei

A line photon incident in an electron-scattering medium is transferred in a diffusive way both in real space and in frequency space, and the mean number of scatterings changes as the wavelength shifts from the line center. This leads to the profile broadening and polarization dependence on the wavelength shift as a function of the Thomson optical depth $\tau_T$. We find that the polarization of the Thomson-scattered emission lines has a dip around the line center when $\tau_T$ does not exceed a few. Various structures such as the polarization flip are also seen. An application to an ionized halo component surrounding the broad emission line region in active galactic nuclei is considered and it is found that the polarization structures may still persist. Brief discussions on observational implications are given.Comment: 14 pages, 3 figures, accepted for publication in ApJ Letter
