Intrusive memories are common following traumatic events and among the hallmark symptoms of posttraumatic stress disorder (PTSD). Most studies assess summarized accounts of intrusions retrospectively. We used an ecological momentary approach and index intrusive memories in trauma survivors with and without PTSD using electronic diaries. Forty-six trauma survivors completed daily diaries for 7 c...

This paper presents a novel architecture for digital identity management. The proposed architecture is highly secure and scales seamlessly across organizational boundaries, while at the same time protecting the privacy interests of individuals and organizations. To achieve these properties, the architecture heavily relies on Digital Credentials, a cryptographic authentication technology specifi...

Available security solutions often are not widely used because the associated secure applications are awkward to use or they lack functionality when compared to standard insecure tools. To avoid this dicothomy, we developed a non-intrusive (or external) clientserver authentication framework which requires no modi cation to both the clients and the servers. In this way, full featured clients can...

Non-Intrusive Load Monitoring (NILM) is a technique that determines the load composition of a household through a single point of measurement at the main power feed. Here we presented an unsupervised approach to determine the number of appliances in the household, their power consumption and the state of each one at any given moment.

Relationships between self-harm and vulnerability factors were studied in a general population of 432 participants, of whom 30% reported some experience of self-harm. This group scored higher on dissociation and childhood trauma, had lower self worth, and reported more negative intrusive thoughts. Amongst the non-harming group, 10% scored similarly to the self-harmers on the dissociation and se...

Individuals who had experienced a range of different traumas were asked to describe the quality and content of their intrusive memories. Visual intrusions were the most common, and thoughts were uncommon. Intrusion quality varied little with type of trauma. Intrusive memories commonly consisted of stimuli that were present immediately before the traumatic event happened or shortly before the mo...

This study explored whether a relatively poor ability to resist or inhibit interference from irrelevant information in working memory is associated with experiencing undesirable intrusive memories. Non-selected participants (N=91) completed a self-report measure of intrusive memories, and carried out experimental tasks intended to measure two different types of inhibition: resistance to proacti...
