Can I follow you? Social media surveillance and policing dilemmas

This research paper explores current open source practices within the Metropolitan Police Service (MPS), with specific attention to social media use by frontline personnel for the purpose of intelligence gathering, investigation and safeguarding. Although, still a relatively new phenomenon for policing, recent advancements have been made in understanding the impact of open source and social media data use in police work, but the focus has been limited to overarching thematical analysis of systems that suggest institutional coordination in their use, function and purpose. This study takes a different approach by focusing on the practices employed by frontline policing personnel in the Metropolitan Police Service and evaluates the concept of ‘localised surveillance’ practices employed by frontline officers that risk undermining police legitimacy at a fundamental level. By identifying localised practices that include the use of personal devices, personal social media accounts and false personas to covertly extract open source and social media data this research considers the shifting power relationship between the police and public in an age where a plethora of personal information is readily available on the internet. At time when traditional surveillance practices are the focus of public enquiry, this timely and relevant research is essential for police services’ nationally and beyond to consider the implications of localised surveillance practices by frontline personnel on their respective agencies and society more widely

Screening of redox couples and electrode materials

Electrochemical parameters of selected redox couples that might be potentially promising for application in bulk energy storage systems were investigated. This was carried out in two phases: a broad investigation of the basic characteristics and behavior of various redox couples, followed by a more limited investigation of their electrochemical performance in a redox flow reactor configuration. In the first phase of the program, eight redox couples were evaluated under a variety of conditions in terms of their exchange current densities as measured by the rotating disk electrode procedure. The second phase of the program involved the testing of four couples in a redox reactor under flow conditions with a varity of electrode materials and structures

Investigation of Metal and Organic Contaminant Distributions and Sedimentation Rates in Backwater Lakes along the Illinois River

Systematic sub-sampling of sediment cores in sections of uniform thickness is necessary in order to evaluate historic changes in sediment quality, to determine the vertical extent of contamination, and to measure sedimentation rates. With these objectives in mind, fourteen sediment cores were collected during March 2002 using the Illinois State Water Survey vibracorer. Concentrations of metals and total organic carbon were measured using standard techniques. Concentrations of chlorinated pesticides, phenolic compounds, polycyclic aromatic hydrocarbons (PAHs), and polychlorinated biphenyls (PCBs) were measured by gas chromatography/mass spectrometry (GC-MS). The concentrations of chlorinated pesticides, phenolic compounds and polychlorinated biphenyls (PCBs) were below the method detection limit in all sediment samples analyzed. However, there was a wide range in concentrations of polycyclic aromatic hydrocarbons (PAHs) which were detected in all sediment samples. Also, a wide range of metal concentrations was noted in the sediments evaluated. Lower concentrations of metals were found in the upper 0.5 m of sediment but concentrations were elevated at depths ranging from 1.0 m to 1.5 m. Sedimentation rates were estimated using cesium-137 radiometric dating on 14 vibracores. Sedimentation rates range from < 0.1 to 1.9 cm/yr, with an average of 0.9 cm/yr. These rates are comparable to those reported in previous studies.Illinois Sustainable Technology Centerpublished or submitted for publicationis peer reviewe

Lessons and Prospects from the pMSSM after LHC Run I: Neutralino LSP

We study SUSY signatures at the 7, 8 and 14 TeV LHC employing the 19-parameter, R-Parity conserving p(henomenological)MSSM, in the scenario with a neutralino LSP. Our results were obtained via a fast Monte Carlo simulation of the ATLAS SUSY analysis suite. The flexibility of this framework allows us to study a wide variety of SUSY phenomena simultaneously and to probe for weak spots in existing SUSY search analyses. We determine the ranges of the sparticle masses that are either disfavored or allowed after the searches with the 7 and 8 TeV data sets are combined. We find that natural SUSY models with light squarks and gluinos remain viable. We extrapolate to 14 TeV with both 300 fb$^{-1}$ and 3 ab$^{-1}$ of integrated luminosity and determine the expected sensitivity of the jets + MET and stop searches to the pMSSM parameter space. We find that the high-luminosity LHC will be powerful in probing SUSY with neutralino LSPs and can provide a more definitive statement on the existence of natural Supersymmetry.Comment: 41 pages, 27 figures. arXiv admin note: substantial text overlap with arXiv:1307.844

Examining the Complex Relationship Between Social Support and Self-Reported Physical and Emotional Status of Older Adults

This exploratory quantitative study was undertaken to examine the complex relationship between social support and the self-reported physical and emotional health status of older adults. The participants (N=30), clients and volunteers of DARTS (Dakota Area Resources and Transportation For Seniors), completed a structured interview consisting of twenty-one questions from two validated questionnaires. The survey measured physical health status, emotional well-being and perceived social support of the participants. The implications of the findings of this study, although complex in nature, are consistent with past studies and will assist DARTS in planning and evaluating services for seniors and their caregivers in Dakota County. One of the most important implications was for social workers to be respectful of older adult\u27s need to maintain social desirability both for themselves and their families. This need requires us to word research questions and inquiries assessing need for services carefully so that respondents can give as accurate information as possible without losing face or threatening their pride and that of their family
