Cyberstalking in the United Kingdom: an analysis of the ECHO Pilot Survey

An Analysis of the ECHO Pilot SurveyNetwork for Surviving Stalking is internationally recognised as the leading Registered Charity in the United Kingdom dedicated to supporting victims of stalking, free of cost or commercial gain. It aims to provide support to victims, potential victims and others affected by stalking or harassment throughout the UK, to raise awareness of the subject and to provide information about stalking and harassment to professionals, relevant agencies and the public. As we have moved into an age of electronic information and communication, stalkers have found new, more effective and efficient means to perpetrate their malicious acts; stalkers have become Cyberstalkers. Cyberstalking has become somewhat of an epidemic stretching across the globe. Network for Surviving Stalking began to notice that an increasing number of people searching for support were being stalked or harassed online, making the charity concerned as to the prevalence, nature and impact of cyberstalking. The charity commissioned a team of researchers and together developed an online questionnaire to establish answers to these questions. This report provides an analysis of the responses to the questionnaire

A beamforming approach to the self-calibration of phased arrays

In this paper, we propose a beamforming method for the calibration of the direction-independent gain of the analog chains of aperture arrays. The gain estimates are obtained by cross-correlating the output voltage of each antenna with a voltage beamformed using the other antennas of the array. When the beamforming weights are equal to the average cross-correlated power, a relation is drawn with the StEFCal algorithm. An example illustrates this approach for few point sources and a 256-element array

Modes of cyberstalking and cyberharassment: measuring the negative effects in the lives of victims in the UK

Cyberstalking may occur solely in the digital realm, or may form part of a wider campaign targeting individuals on and off-line. The impact cyberstalking has on victims may differ depending on the type. In this paper, we use Sheridan and Grant's (2007) classifications of, "Proximal with offline", "Online only" and "Cross-over" stalking types. These classifications are applied to responses gathered from 278 victims of cyberstalking and cyberharassment through the 2011-2014 ECHO survey. We analyse the responses to first classify the type of stalking experienced and then the reported number and types of effects in the life of the victims on a per-group basis. Using chi-square analysis, we identify that victims in the case of proximal and Cross-over stalking are significantly more likely to report negative changes to their work, relationships and financial lives and to report more negative changes in these areas than those experiencing online only. In addition, in the relationship category Cross-over cases provoke significantly more changes than proximal cases. This indicates that cases where the stalker moves from being an online presence to a proximal presence have an extreme impact and therefore should be treated with the utmost concern, both in terms of support and safeguarding strategies

Towards a Jōmon food database: construction, analysis and implications for Hokkaido and the Ryukyu Islands, Japan

One of the most entrenched binary oppositions in archaeology and anthropology has been the agriculturalist vs hunter-gatherer-fisher dichotomy fuelling a debate that this paper tackles from the bottom-up by seeking to reconstruct full past diets. The Japanese prehistoric Jōmon cultures survived without fully-developed agriculture for more than 10,000 years. Here we compile a comprehensive, holistic database of archaeobotanical and archaeozoological records from the two ends of the archipelago, the northernmost prefecture of Hokkaido and the southernmost island-chain of Ryukyu. The results suggest Jōmon diets varied far more geographically than they did over time, and likely cultivated taxa were important in both regions. This provides the basis for examining how fisher-hunter-gatherer diets can fulfil nutritional requirements from varied environments and were resilient in the face of environmental change

Gibbs optimal design of experiments

Bayesian optimal design of experiments is a well-established approach to planning experiments. Briefly, a probability distribution, known as a statistical model, for the responses is assumed which is dependent on a vector of unknown parameters. A utility function is then specified which gives the gain in information for estimating the true value of the parameters using the Bayesian posterior distribution. A Bayesian optimal design is given by maximising the expectation of the utility with respect to the joint distribution given by the statistical model and prior distribution for the true parameter values. The approach takes account of the experimental aim via specification of the utility and of all assumed sources of uncertainty via the expected utility. However, it is predicated on the specification of the statistical model. Recently, a new type of statistical inference, known as Gibbs (or General Bayesian) inference, has been advanced. This is Bayesian-like, in that uncertainty on unknown quantities is represented by a posterior distribution, but does not necessarily rely on specification of a statistical model. Thus the resulting inference should be less sensitive to misspecification of the statistical model. The purpose of this paper is to propose Gibbs optimal design: a framework for optimal design of experiments for Gibbs inference. The concept behind the framework is introduced along with a computational approach to find Gibbs optimal designs in practice. The framework is demonstrated on exemplars including linear models, and experiments with count and time-to-event responses

High-resolution and high-accuracy topographic and transcriptional maps of the nucleosome barrier.

Nucleosomes represent mechanical and energetic barriers that RNA Polymerase II (Pol II) must overcome during transcription. A high-resolution description of the barrier topography, its modulation by epigenetic modifications, and their effects on Pol II nucleosome crossing dynamics, is still missing. Here, we obtain topographic and transcriptional (Pol II residence time) maps of canonical, H2A.Z, and monoubiquitinated H2B (uH2B) nucleosomes at near base-pair resolution and accuracy. Pol II crossing dynamics are complex, displaying pauses at specific loci, backtracking, and nucleosome hopping between wrapped states. While H2A.Z widens the barrier, uH2B heightens it, and both modifications greatly lengthen Pol II crossing time. Using the dwell times of Pol II at each nucleosomal position we extract the energetics of the barrier. The orthogonal barrier modifications of H2A.Z and uH2B, and their effects on Pol II dynamics rationalize their observed enrichment in +1 nucleosomes and suggest a mechanism for selective control of gene expression

An estuarine tide-scape of production: terrestrial laser scanning (TLS) of fixed fishing structures and a tidal mill in the Léguer Estuary, Brittany, France

Terrestrial laser scanning (TLS) provides a means of rapid and highly accurate survey of archaeological excavations and structures at landscape scales, and is particularly valuable for documenting tidal environments. Here, the authors use TLS to record tidal fixed fishing structures and a tide mill within the Léguer Estuary at Le Yaudet, in north-west France. As part of a comprehensive resource-exploitation system, the early medieval (sixth to eighth centuries AD) structures lie within, and exploit different parts of, the tidal frame. The results are used to quantify production within an estuarine landscape associated with seignorial or monastic control of environmental resources

Program okruglog stola - Javno i privatno u zdravstvu i ljekarništvu: Dvije logike, dvije etike?

This paper examines interactions between co-occupants of riverine niches in north-west Europe during the Late Upper Palaeolithic using both ecological and archaeological data. It is argued that consideration of both the Lateglacial record and autecology of eel, beaver and horse supports a reinterpretation of some famous but enigmatic panels of Magdalenian mobiliary art as representations of eel fishing, along with horse and beaver exploitation in disturbed riverine habitats. It is further suggested that this constitutes a humanly co-constructed niche in ecological, nutritional, and symbolic terms, which was also particularly advantageous for human well-being and social development in this time and place
