From a complete characterization in terms of noise and scattering parameters carried out at room temperature in the 8–16 GHz frequency range, the noisy small‐signal model of a pseudomotphic HEMT series has been extracted. The transistor scattering parameters have been subsequently measured at lower temperatures (down to −50 °C) by placing the device text fixture in a thermo‐controlled chamber. The model effectiveness has then been tested by determining the circuit element values at the different temperatures and by observing the model noise performance.

Noise parameters of high electron mobility transistors (HEMT) at microwave frequencies are a subject of active research since the knowledge of their performance is of key importance for the use of these devices for designing low‐noise amplifiers. Employs a simple noise model to derive the analytical expressions for the device noise parameters F₀, Γ₀ and N in terms of the electrical elements associated with the basic equivalent circuit of an HEMT. Analyses such expressions to establish some fundamental relationships, as well as the expected noise performance of the device when the parasitic elements representing package effects are included.

There has been growing concern among stakeholders about individuals with autism spectrum disorders (ASD) and sex offending as research supports an indirect association. The purpose of this paper is threefold: first, bring more awareness of the sexuality and deviant/criminal sexual behavior among those with ASD to stakeholders in the criminal justice system (CJS); second, demonstrate that much of the deviant or sexual offending behavior exhibited among those with ASD is often a manifestation of their ASD symptoms and not malice; and third, demonstrate the necessity to address specific needs of individuals with ASD who enter the CJS due to criminal sexual behavior.

This paper provides an overview of the ASD symptomology, including the diagnostic changes, a review of the literature on ASD and sexuality, which includes deviant sexual behavior and sexual offending.

The author linked examples of deviant or sexual behavior in the research literature to the ASD symptomology and described how the symptomology explains such behavior.

Sexual offending among those with ASD has received little research outside the mental health field. This review is of particular importance to those in the CJS unfamiliar with ASD, as they should handle them differently with regard to formal interviewing, measures of competency, capacity, and sentencing.

As recently highlighted by Creaby-Attwood and Allely (2017), it is crucial that the possible innate vulnerabilities that contributed to sexual offending behaviour in an individual with an autism spectrum disorder (ASD) are taken into consideration for the application of a diversion programme to avoid the stigma of a criminal conviction or during sentencing for a non-custodial outcome. Specifically, in those defendants with a diagnosis of what used to be referred to as Asperger’s syndrome (AS) and now is recognised as an ASD and who are charged and convicted of a non-contact sexual offense, education and mental health intervention will best serve the interests of justice. The paper aims to discuss this issue.

This paper focusses on one particular type of sexual offending behaviour, namely, possession of child pornography. A systematic PRISMA review was conducted.

The authors linked examples of child pornography in the research literature to the ASD symptomology and describe how the symptomology explains such behaviour as not reflecting actual sexual deviance.

Downloading and viewing of child pornography by individuals with ASD has received relatively little research outside the mental health field. This review is of particular importance to those in the criminal justice system who may not have much knowledge and understanding of ASD. It is suggested that diversion programmes and mental health courts should be set up for this particular population charged with this particular crime in mind so that the necessary treatment/intervention/support and care can be given to this particular group.

The purpose of this paper is to add to the relatively limited existing literature exploring the experience of individuals with autism spectrum disorder in the prison environment. Prisoners with autism spectrum disorder (ASD) need to be identified in order that they are given the necessary and appropriate support and safeguards. It is increasingly recognised that, for individuals with ASD, prison can be more challenging. This can be due to ASD traits which can make problems occur in everyday life. Some of these ASD traits include: obsessions, compulsions and difficulties in communicating with others. There is increasing recognition that adults with ASD who are in prison are more vulnerable to bullying, social isolation, sexual victimisation and exploitation confrontations with other prisoners. Given this, more research is warranted in this area highlighting the specific needs and challenges of individuals with ASD in the prison.

This paper is a case study of Mr C.T., a British Citizen, who is currently serving a life sentence (discretionary). Mr C.T. has spent more than 10 years in prison. At the time of completing the questionnaire for the present study, Mr C.T. was 51 years of age. He pled guilty to charges of lewd, indecent and libidinous practices and behaviour; making an indecent photograph contrary to s52(1)(a) of the Civic Government (Scotland) Act 1982; and possession of indecent photographs contrary to s52(A)(1) of the Civic Government (Scotland) Act 1982. Mr C.T. was convicted of Lewd, Indecent and Libidinous Practices and Behaviour and 2 x Civic Government (Scotland) Act, Section 52 (1) (a) and was sentenced to Life Imprisonment with a punishment part of 6 years.

The case study discussed in this paper clearly raises a number of issues and concerns that urgently need attention in our criminal justice systems.

There is relatively little research exploring the experiences and challenges faced by individuals with ASD. This paper will add to the existing body of research in this limited field.

Allely and Dubin (2018) and Allely et al. (2019) have emphasised that there are a range of innate vulnerabilities in many individuals with autism spectrum disorder (ASD) who are charged with the viewing of indecent images of children (IIOC). Currently, the association between ASD and the viewing of IIOC is poorly recognised and understood both by the general public and clinical and legal professionals.

This is a detailed case study exploring the contributory role of ASD symptomology in the viewing of IIOC. In this case study, the experience of the criminal justice system is also explored.

It is hoped that this case study will provide insight into and understanding of how ASD can in some cases be the context for vulnerability to the viewing of IIOC and raise awareness of the need to consider this at all stages of the criminal justice system, including while making sentencing decisions. This case study paper will also more effectively inform the development of appropriate preventative strategies and timely interventions.

To the best of the author’s knowledge, this is the first detailed case study which explores the contributory role of ASD symptomology in the viewing of IIOC in the academic peer-reviewed literature.

Despite an increasing number of studies that examine sexual offending behaviour in autism spectrum disorder (ASD) individuals, there has been a lack of research investigating stalking and ASD. This study aims to carry out a scoping review following PRISMA guidelines to identify studies which have been carried out exploring stalking behaviour in individuals with threshold or subthreshold ASD.

A total of five bibliographic databases were searched to identify studies which explored ASD in relation to stalking and harassment (including case studies as well as empirical studies).

A total of five relevant articles were identified in the present review. One article contained a case study. In a short report, the authors discussed stalking and ASD. One paper explored ASD and stalking behaviour in employment settings and specific interventions that could be used in such environments. Another paper focused on stalking behaviour in those with ASD in school settings. The final paper examined stalking and social and romantic functioning in individuals with ASD. This final paper contained only the empirical study identified in this search.

The studies identified in this review clearly highlight the need for intensive socio-sexual interventions to improve social interaction skills and romantic functioning in individuals with ASD. There is also a need for schools to provide sex education programs for individuals with ASD.

To the best of the authors’ knowledge, this is the first review looking at ASD and stalking.

Autism-specific characteristics have been associated with internet criminal activities. Internet and non-internet offenders differ on a series of demographic, psychological and offending variables. However, the clinical and criminal presentation of individuals with autism spectrum disorder (ASD) in forensic secure care settings has been underexplored. This paper aims to explore the profiles of internet offenders with ASD admitted to a secure psychiatric unit.

This study provides the results of a service evaluation of individuals with ASD. The demographic, clinical and criminal characteristics of a small sample of internet offenders with ASD admitted to secure care are described and discussed.

Internet offenders present in secure care with high rates of comorbid disorders, histories of violence and traumatic experiences, mood disorders and difficulties with relationships. Of the 24 internet offenders discussed, 18 of them committed an offence of a sexual nature involving children.

This paper highlights the potential risks for individuals with ASD in using the internet and the possible difficulties associated with detecting this because of rapid advancements in technology.

The purpose of this paper is to examine the effects of golden parachutes on shareholders' wealth when the measure is used as a compensation device instead of a takeover defense. The results show that the adoption of the measure has a negative influence on shareholders' wealth. These negative results are more prevalent for firms with an operating performance above their industry peers and are significantly influenced by the previous performance of the firm and the size of the golden parachute.

Event study and regression analysis.

The results show that the adoption of the measure has a negative influence on shareholders' wealth. These negative results are more prevalent for firms with an operating performance above their industry peers and are significantly influenced by the previous performance of the firm and the size of the golden parachute.

Investors will have more information about the reaction of stock markets at the announcement of golden parachutes.

The paper presents a new evaluation of the adoption of golden parachutes on shareholders' wealth when the measure is used as a compensation device instead of a takeover defense.

This study aims to investigate the association between vitamin D measured in serum 25 hydroxyvitamin D [25(OH)D] and outcomes of COVID-19 patients in Bahrain. This paper hypothesized that lower serum 25(OH)D concentration in COVID 19 patients is associated with longer viral clearance time (VCT) and higher risk of admission to the intensive care unit (ICU).

This study used a retrospective cohort design of patients admitted to Salmaniya Medical Complex, Manama, Kingdom of Bahrain, from February to June 2020. This study included patients with positive, confirmed COVID-19 diagnosis made using reverse transcription-polymerase chain reaction (RT-PCR), World Health Organization diagnosis manual and local diagnostic guidelines. Primary outcome measures were: VCT measured as the time in days between the first positive RT-PCR test result and the first of two consecutive negative RT-PCR results on recovery and admission need to ICU.

A total of 450 patients were analyzed; mean age was 46.4 ± 12.4 years and 349 (78%) were men. Mean 25(OH)D concentration was 41.7 ± 23.7 nmol/L for the entire sample. Severe vitamin D deficiency (<25 nmol/L) was present in 20%, mild-to-moderate deficiency (25–50 nmol/L) in 55%, insufficiency (50 to <75 nmol/L) in 18% and sufficiency (=75 nmol/L) in 7%. The mean VCT was 12.9 ± 8.2 days. Multivariate linear regression analysis showed that severe vitamin D deficiency was associated with longer VCT, with an average of three extra days after correction for age and sex (β = 3.1; p = 0.001). Multinomial regression analysis showed that vitamin D deficiency was associated with an 83% increased risk of admission to ICU after correction for age and sex (odds ratio = 1.8; p = 0.03).

The results showed that severe vitamin D deficiency was associated with longer recovery time from COVID-19. Low serum 25(OH)D is associated with increased need for critical care in an ICU. Large-scale randomized controlled trials are necessary to further investigate the complex association between vitamin D and COVID-19 infection.
