Currently, most biometric methods mainly use single features, making them easily forged and cracked. In this study, a novel triple-layers biometric recognition method, based on photoacoustic microscopy, is proposed to improve the security of biometric identity recognition. Using the photoacoustic (PA) dermoscope, three-dimensional absorption-structure information of the fingers was obtained. Then, by combining U-Net, Gabor filtering, wavelet analysis and morphological transform, a lightweight algorithm called photoacoustic depth feature recognition algorithm (PADFR) was developed to automatically realize stratification (the fingerprint, blood vessel fingerprint and venous vascular), extracting feature points and identity recognition. The experimental results show that PADFR can automatically recognize the PA hierarchical features with an average accuracy equal to 92.99%. The proposed method is expected to be widely used in biometric identification system due to its high security. This article is protected by copyright. All rights reserved.

This study investigates the important attributes of online banking system for Small and Medium Enterprises (SMEs) and their willingness to pay for each attribute. Zero travel and waiting time, high security, and 24/7 accessibility are the key attributes for this service. The results show that SMEs engaged in international trade value online banking services significantly more than the others. Domestically focused firms value high‐quality service at about $163 a month, while import‐focused businesses value such a service at approximately US$646 per month. Export‐intensive SMEs value high‐quality online services 14% further, for an average of $736 per month.

The discourse surrounding personality disorder is largely negative, and the diagnosis is considered to be associated with a degree of stigma. This study aimed to investigate staff attitudes towards personality disorder in high-security and medium-security forensic-psychiatric hospitals in the UK. The Attitude to Personality Disorder Questionnaire was completed by 132 participants who were all current employees with clinical roles. Staff attitudes to personality disorder in the current study were significantly less positive than in comparable studies in similar settings. Having completed staff training surrounding personality disorder and being from a non-nursing professional background were the best predictors of positive attitudes to personality disorder. The findings of this study offer support to the pursuit of improving access to training in personality disorder for those working with this clinical presentation.

In this paper, we revisit King and McDermott's 1990 article on the social construction of 'control problem' prisoners and their management in high security prisons, in the light of our recent research on the location and building of trust in contemporary high security prisons. We examine how religious and race identities are now deeply implicated in the construction of risk, and we describe the procedures for and some of the consequences of managing the new risks of radicalization and extremist violence in prison. The analysis is based on observations and interviews with staff and prisoners in two main and two supplementary maximum-security prisons in England and Wales.

Links between mother-infant affective matching and attachment security are well-documented, but research on other types of behavioral matching and attachment security are lacking, as are studies that examine these constructs later in children's development. We examine language style matching (LSM) between mothers and their school-aged children (N = 68), using interviews with each dyad member. As predicted, regressions revealed that higher mother-child relational LSM was associated with greater child attachment security (operationalized as high security, low dismissal), and that higher LSM predicted smaller increases in children's electrodermal response to a relational probe 1.5 years later. Further, mother-child relational LSM was a mediator in the indirect path between children's attachment security and children's reactivity. We discuss the potential utility of LSM as a measure of relationship quality and future studies that could refine our understanding of parent-child language matching.

In the majority of threshold multi-proxy multi-signature TMPMS schemes, only one proxy group is authorized to sign on behalf of all the original members. However, the original signers in various practical applications are often from different organizations. Each original signer should be able to designate a proxy group in his own organization; thus, each original signer could have distinct proxy members. However, this practical requirement of TMPMS schemes is seldom considered. To satisfy this requirement, we propose a new TMPMS scheme in which each original member can designate a proxy group in his own organization. Moreover, the threshold value of each proxy group is unique. We develop a security model to prove the high security and strong unforgeability of the proposed scheme. We analyze the security of our scheme based on the four types of adversaries tested in the security model. Compared with previous schemes, the new scheme offers higher security and superior computational efficiency. Copyright © 2013 John Wiley & Sons, Ltd.

Introduction The Special Hospitals in England provide psychiatric treatment in high security. The aim of this study was to examine the demographics and background characteristics of children admitted to high security hospitals in England, using the special hospital case register. Method Forty-six children (the subject group) were admitted to a high security hospital under the MHA (1983) classification of disorder of mental illness and/or psychopathic disorder between 1983 and 1999, 33 (72%) of whom were male. A comparison group of adults was matched on sex, legal classification of detention and MHA 1983 classification of disorder. Results The children were admitted for a similar range of offences to those of the comparison group. However, the children had received convictions for criminal damage and violence at a significantly earlier age, they were more likely to have experienced a change in carer during their childhood, been placed in a children's home and were less likely to be living with a family member on their 16th birthday. Children admitted to special hospital experience a lot of disruption in their childhood and are extremely high users of multi-agency services as they grow up. Discussion Issues are raised regarding how to provide a developmentally sensitive service for children who require high security care. Copyright © 2003 Whurr Publishers Ltd.

One claim about I, regularly made and almost universally endorsed, is that uses of the term are logically guaranteed to refer successfully (if they refer at all). The claim is only rarely formulated perspicuously or argued for. Such obscurity helps disguise the fact that those who profess to advance the claim actually turn out to support not a logical guarantee at all but merely high security through fortunate coincidence. This is not surprising. For we have no good reason to accept the claim – granted, any use of I is apt to refer successfully; but that can be explained by pragmatic features of its use. And we have some reason to reject the claim – it is notoriously difficult to see how genuine reference and guaranteed success do not exclude each other when considered as properties of the logic of any term.

Appreciative Inquiry was used to highlight the successes of a donor-supported project of working with victims of trauma in an environment of civil war and high security risk, and thereby also to honor the work of dedicated staff who often face extremely difficult situations.

Background Various studies suggest that 20–30% of patients in England and Wales in high security could be safely managed in medium security but there are no objective criteria and little attention has been paid to differences of opinion. Method The authors compare the views of the referring and receiving team on the security needs of all special hospital patients from two London health authorities. Results Disagreements were found in only 8% of cases, and they were more likely to occur in patients detained under the legal category of psychopathic disorder. Between 21% and 33% of patients were rated as misplaced by one or other team but these figures include patients who were either already on trial leave in another hospital or on the waiting list for an identified placement. Patients for whom there was agreement on misplacement, with no identified route out of high security, account for 9% of the total. Most patients with treatment-resistant schizophrenia were not receiving atypical anti-psychotic medication. Discussion It may be more realistic to plan future services on the basis that only 9% of patients are misplaced, rather than the previous estimates that appear to have guided current policy. Patients detained under the legal category of psychopathic disorder present particular problems and there is a need to develop appropriate facilities at medium secure level. In the meantime, no patients should be admitted to high security without consultation with the catchment area service and a jointly agreed plan for future rehabilitation.

Background The State Hospital, Carstairs, is the sole high security psychiatric facility for Scotland and Northern Ireland. Method This study compares the female (n = 28) and male (n = 213) patients resident there between 1992 and 1993 using data derived from case-note reviews and interviews with patients and staff. Results Nearly three-quarters of both the male and female populations had a primary diagnosis of schizophrenia, and secondary diagnoses of substance abuse and antisocial personality disorder were common. Female patients were more frequently admitted from other psychiatric hospitals, had less serious index offences and more minor previous convictions, and were less likely to be subject to a restriction order. They had more often experienced depressive symptoms and had significantly greater histories of self-harm, physical and sexual abuse. At interview, nearly three-quarters had active delusions and over half had recently behaved in an aggressive manner. Almost 90% were said not to require the security of the State Hospital. Conclusions It was concluded that mental illness and adverse social circumstances had combined to create a very disadvantaged group of women in high security psychiatric care in Scotland. As a group these women were inappropriately placed and their requirement was for intensive, rather than high security psychiatric care. Copyright © 2001 Whurr Publishers Ltd.

INTRODUCTION: For England and Wales, Section 17 of the Mental Health Act 1983 allows for compulsorily detained patients to have trial leave (TL) between hospitals or from hospital to community to allow a period of testing readiness for a change in residency and/or legal status. The aim of this study was to document the use of TL for the largest sub-group of such patients within two discharge cohorts from one high security hospital and to test for correlates. METHOD: Data were collected from the special hospitals' case register for two Broadmoor Hospital discharge cohorts, 1984 and 1990-94, of offender patients with hospital orders under Home Office restrictions on discharge (Section 37/41). RESULTS: In 1984, only two of the 29 people leaving special hospital did so under trial leave arrangements, but by 1990 to 1994, 71% of restricted hospital order departures were under trial leave (92/130), a significant change in practice. Focusing on only the later cohort, women were disproportionately more likely to leave in this way. Trial leave was used more for patients with an index offence of homicide, similarly for violent offences but less so for sex offences. Nature of disorder did not have any bearing on the use of trial leave. Use of trial leave did not significantly shorten length of stay within the special hospital. CONCLUSION: Trial leave has become the most usual route out of special hospital, and is the departure route used almost exclusively for women patients, yet there appears to be no obvious advantage for the patient in shortening length of stay in high security. However, there is no way of knowing how long patients would have stayed had the option of trial leave not been available to them. Furthermore, no advantage for the public was found in the preferential use of TL for discharges to the community.

Introduction There is now a large amount of data demonstrating the internal reliability and construct validity of the Hare Psychopathy Checklist (PCL/PCL-R) when used in the assessment of psychopathy in male forensic populations. It has well-established psychometric properties when scored following a review of collateral information and a subsequent interview. However, its internal reliability and factor structure, when casenote information alone has been used, have not been examined outside North America. Method A sample of 89 patients from a British high security hospital, with the legal classification of psychopathic disorder, was scored retrospectively on the PCL-R from their medical files only. The psychometric properties of the PCL-R were analysed. Results The PCL-R ratings showed a high level of internal reliability. The factor structure was very similar to that found in Hare's North American sample of forensic psychiatric patients. Discussion The findings support the application of the PCL-R, when scored using existing file data alone, to a British high security hospital population. Copyright © 2001 Whurr Publishers Ltd.

Background Few follow-up studies of mentally disordered offenders have taken into account time spent in the community at risk of reoffending when calculating reconviction rates. Method This small exploratory study examined the effect of discharge destination (community or hospital) on reconviction over a nine-year period in an annual discharge cohort (1984) of special hospital patients with personality disorder, controlling for time spent ‘at risk’ in the community. Results Those discharged directly to the community spent significantly more time at risk in the community during follow-up but they were no more likely to be reconvicted than those discharged via a less secure hospital. Discussion One possible explanation is that less secure hospital units are not specifically equipped to treat people with a personality disorder. Alternatively, clinicians may be correctly identifying patients who are at greater risk of reoffending and thus recommending a more staged rehabilitation back to the community. It was apparent that there are very few official data available about placements following absolute discharge. The implications for this and other studies of this type are discussed.

Experimental data from several performance and sensitivity tests have been combined after normalization to define a single performance and a security characteristic term, respectively. This allows to evaluate pure compounds and special formulations with regard to a well balanced ratio of performance and sensitivity. A graph shows an imaginary border line what has to be interpreted in the sense that–in the praxis of explosive charges–high performance is accompanied by an enhanced sensitivity and that an insensitive explosive will not exhibit a top performance. As this result cannot be proved by theory one should imagine that there are also exceptions, i.e. explosives which approach the ideal high explosive (with high performance and high security) what is exemplified.

This paper reviews the literature regarding the diversion of mentally disordered offenders from the criminal justice system to the mental health services, with a specific focus on the high security psychiatric special hospitals. The traditional sources of admission to these institutions have been predominantly courts and prisons, with the majority of patients being admitted via the former route. This study reports on the admissions to a special hospital over a 20-year period, and shows that over the previous decade there has been a reversal in this trend, with the number of patients transferred from prison being greater than that via any other route. The factors that may have contributed to this reversal are discussed and conclusions are drawn as to the external and internal forensic factors that may influence the court's decision in the referral process.

The majority of psychiatric patients, even those who also offend against the law, are likely to be served best by good community services but a few of them will need treatment in a secure hospital. Treatment in high security for patients from England and Wales is provided by three special hospitals. In the 1980s provision of medium-secure hospital units began, but there is still a considerable shortfall of such beds. Data from a variety of settings suggest that the continuing gap in medium-secure provision may be qualitative as well as quantitative. This paper considers the case for long-term medium security, and the likely size and nature of demand. It would be misleading to assume that those with long-term medium-security needs constitute a homogeneous group. Some new facilities, probably built on to existing medium secure hospital units, are likely to be needed; if estimates of real need for high-security places are correct, then some places already exist and are being used by default in the special hospitals. For some patients, notwithstanding the old image of special hospitals, these may be ideal placements if redesignated, even redesigned. A variety of provision and effective cooperation between purchasers and providers will be essential to satisfy real need and ensure that the number of patients needing secure accommodation remains more or less within present estimates.

Currently, there are many parking lot management systems in use; however, most of them are unsuited to the problem of car theft. For example, a thief can drive a jalopy into a parking lot, and because the gate does not have any mechanism to detect whether the driver is the owner of the car, the gate will be open according merely to whether the driver pays the parking fee. A thief can drive away with a luxurious car away using his own parking ticket. We propose a new scheme to prevent the car theft. We adopt radio frequency identification technology conforming to EPCglobal Class 1 Generation 2 to our scheme design. Our scheme supplies an easy, cheap and high security parking environment for customers and the parking management system. Copyright © 2012 John Wiley & Sons, Ltd.

Mood changes over the bulimic binge–purge cycle were studied in retrospective questionnaire reports of patients, 16 with and 34 without concurrent affective disorder. Moods clearly differed over phases. Mood reports depicted the period between the binge and purge as most unpleasant, with low energy/excitement and security/relief and high panic/helplessness and guilt/disgust/anger. Feelings after the purge were relatively calm and pleasurable, with low panic/helplessness and excitement/energy and high security/relief. Patients with affective disorder did not differ from those without affective disorder in their mood changes during the cycle.
