The Paranoid file system is an encrypted, secure, global file system with user-managed access control. The system provides efficient peer-to-peer applicationtransparent file sharing. This paper presents the design, implementation and evaluation of the Paranoid file system and its access-control architecture. The system lets users grant safe, selective, unix-like, file access to peer-groups acro...

The main purpose of the present study was to examine implicit and explicit self-esteem (SE) in patients with persecutory delusions. In samples of paranoid patients, depressed patients and healthy controls, implicit SE was assessed using the experimental task of Go/No-Go association, while explicit SE was measured using two self-reporting questionnaires: the World Assumption Scale (WAS) subscale...

This review examines the literature on neuropsychological differences between paranoid and nonparanoid schizophrenia subjects. Thirty-two studies related to intellectual functioning, attention, memory, language, visual-spatial, and motor functions are discussed. Subjects with paranoid schizophrenia did not demonstrate higher intellectual functioning than those with nonparanoid schizophrenia, an...

The paranoid has traditionally been considered schizophrenic except for some rare cases which exhibit delusions but none of the other signs such as cognitive disorganization. We attempt to show that considering the paranoid as independent of schizophrenia and exhibiting varying degrees of pathology is more consistent with current research. Furthermore, we believe that there is enough descriptio...

I he paranoid patient suffers deeply from pervasive feelings of being mistreated and misunderstood, hypervigilance, and an acute sensitivity to real or imagined slights. He is suspicious of other people's motives and may distrust those he loves most or to whom he is most attached. This patient harbors simmering anger and grudges toward those he feels may have deceived him or taken unfair advant...

conclusions after eight sessions, increased awareness of the environment, improved posture and gait pattern, improved motivation and enjoyment, improved patient tolerance, improved appearance and personal hygiene, loss of purposeful behavior, a realistic plan of action every day, improved attention span, improved decision-making skills, and improved community involvement and coping skills were ...

Although social cognition deficits have been associated with schizophrenia, social trait judgments - or first impressions - have rarely been studied. These first impressions, formed immediately after looking at a person's face, have significant social consequences. Eighty-one individuals with schizophrenia or schizoaffective disorder and 62 control subjects rated 30 neutral faces on 10 positive...

BACKGROUND Paranoia is one of the commonest symptoms of psychosis but has rarely been studied in a population at risk of developing psychosis. Based on existing theoretical models, including the proposed distinction between ‘poor me’ and ‘bad me’ paranoia, we aimed to test specific predictions about associations between negative cognition, metacognitive beliefs and negative emotions and paranoi...

BACKGROUND There has been renewed interest in the influence of affect on psychosis. Psychological research on persecutory delusions ascribes a prominent role to cognitive processes related to negative affect: anxiety leads to the anticipation of threat within paranoia; depressive negative ideas about the self create a sense of vulnerability in which paranoid thoughts flourish; and self-consciou...

The main purpose of the present study was to examine implicit and explicit self-esteem (SE) in patients with persecutory delusions. In samples of paranoid patients, depressed patients, and healthy controls, implicit SE was assessed using the experimental go/no-go association task, whereas explicit SE was measured using 2 self-reporting questionnaires: the self-worth subscale of the World Assump...
