Determination of Flaw Growth Characteristics of Ti-6Al-4V Sheet in the Solution-Treated and Aged Condition

The specific experimental investigation undertaken was designed to answer these questions on Ti-6Al-4V in the solution treated and aged condition. The defect growth and fracture characteristics were studied in parent (unwelded) and welded sheet material. The results of the study indicate that cryogenic proof testing will screen smaller size defects than proof testing at ambient conditions. However some unusual crack growth behavior during the proof test simulation suggests that some further study be made of stress and time duration effects

Reasons for non-suicidal self-harm in adult male offenders with and without borderline personality traits

The presented study aimed to advance understanding of the reasons for non-suicidal self-harm (NSSH) in adult male offenders, with and without borderline personality traits. 179 offenders completed self-report measures of NSSH and other clinical constructs, with 42 being identified as having self-harmed. Results were consistent with past research and supported the relative importance of intrapersonal over interpersonal functions, but also highlight that self-harm is performed rarely for one type of reason. The results also show that the presence of borderline personality traits increases the likelihood of endorsing a range of interpersonal reasons. These findings highlight the importance of understanding the range of reasons for engaging in NSSH to help manage the behaviour within the priso

Sexual coercion perpetration and victimisation in females: The influence of borderline and histrionic personality traits, rejection sensitivity, and love styles

This study investigated sexual coercion (perpetration and victimisation) in women. Women (N = 151) aged 18–63 years (M = 23.34, SD = 8.80) completed standardised questionnaires measuring sexual coercion (nonverbal sexual arousal, emotional manipulation and deception, and exploitation of the intoxicated), personality disorder traits (Borderline and Histrionic), love styles (Eros, Ludus, Storge, Pragma, Mania, and Agape), and rejection sensitivity. Data analyses revealed that together, personality disorder traits, love styles, and rejection sensitivity predicted coercion perpetration involving emotional manipulation and deception. These variables also predicted victimisation involving nonverbal sexual arousal and emotional manipulation and deception. Of these predictors, borderline traits predicted coercion involving emotional manipulation and deception (as both a perpetrator and victim) and victimisation from nonverbal sexual arousal-based coercion. Furthermore, Ludus predicted victimisation involving emotional manipulation and deception, while rejection sensitivity predicted the use of emotional manipulation and deception to coerce a partner

Borderline personality traits, rumination and self-injurious behavior: An empirical test of the emotional cascades model in adult male offenders

The aim of the study was to examine whether the emotional cascade model, which suggests that the relationship between emotional and behavioural dysregulation in Borderline Personality Disorder (BPD) is mediated by rumination, applies to a sample of adult male offenders. The study focused on individuals with “BPD traits” and two dysregulated behaviors that are particularly relevant to the prison population: non-suicidal self-injury (NSSI) and suicidality. Participants were 179 adult male offenders detained in a medium-secure prison, all of whom completed a battery of measures and self-reported their actual prison behaviour. The results support the application of the emotional cascade model to adult male offenders, suggesting that emotional cascades may play an important role in NSSI and suicidality in this population, although this relationship needs further exploration. These findings highlight the benefits of targeting rumination to manage risk of NSSI and suicidality within custodial settings

Posttraumatic stress symptoms mediate the relationship between adverse childhood experiences, avoidant personality traits and resilience

Background and Objectives: It is widely recognized that posttraumatic stress (PTS) symptoms, resulting from adverse childhood experiences (ACEs), have myriad detrimental effects on the wellbeing of sufferers. Yet the extent to which PTS symptoms mediate positive and negative outcomes is less well-known. This study therefore explored whether PTS symptoms indirectly explain avoidant personality disorder (AVPD) traits and resilience following multiple ACEs. Design: A correlational design using mediation analyses was conducted. Method: One-hundred and seventy-seven participants (68.4 % female; aged 18-73 years) completed an online survey measuring experiences of childhood adversity, AVPD traits, resilience, and PTS symptoms. Results: The pathway from ACEs to AVPD mediated by PTS symptoms was both positive and significant. The indirect relationship from ACEs to resilience was also significantly and negatively mediated by PTS symptoms. Of the PTS dimensions, avoidance and hyperarousal mediated the relationship between the number of ACEs and AVPD traits, while intrusions mediated the association between the number of ACEs and resilience. Conclusions: These findings indicate that PTS symptoms can have both detrimental and adaptive effects on psychological wellbeing. Treatment and management of PTS symptoms is therefore key to the improvement of overall psychological functioning following ACEs

The addition of a goal-based motivational interview to standardised treatment as usual to reduce dropouts in a service for patients with personality disorder: a feasibility study

<p>Abstract</p> <p>Background</p> <p>Rates of non-completion of treatments for personality disorder are high and there are indications that those who do not complete treatment have worse outcomes than those who do. Improving both cost-efficiency and client welfare require attention to engaging people with personality disorder in treatment. A motivational interview, based on the Personal Concerns Inventory, may have the ability to enhance engagement and retention in therapy. Here, we report the protocol for a feasibility study for a randomised controlled trial (RCT).</p> <p>Methods</p> <p>All referrals accepted to the psychological service of Nottinghamshire Healthcare NHS Trust's outpatient service for people with personality disorder are eligible for inclusion. Consenting participants are randomised to receive the Personal Concerns Inventory interview plus treatment as usual or treatment as usual only. We aim to recruit 100 participants over 11/2 years. A randomised controlled trial will be considered feasible if <abbrgrp><abbr bid="B1">1</abbr></abbrgrp> the recruitment rate to the project is 54% of all referrals (95% CI 54-64), <abbrgrp><abbr bid="B2">2</abbr></abbrgrp> 80% of clients find the intervention acceptable in terms of its practicability and usefulness (95% CI 80-91), and <abbrgrp><abbr bid="B3">3</abbr></abbrgrp> 80% of therapists report finding the intervention helpful (95% CI 80-100). In a full-scale randomised controlled trial, the primary outcome measure will be completion of treatment i.e., entry into and completion of ≥ 75% of sessions offered. Therefore, information will be collected on recruitment rates, attendance at therapy sessions, and completion of treatment. The feasibility of examining the processes of engagement will be tested by assessing the value, coherence, and attainability of goals pre-treatment, and engagement in treatment. The costs associated with the intervention will be calculated, and the feasibility of calculating the cost-benefits of the intervention will be tested. The views of clients and therapists on the intervention, collected using semi-structured interviews, will be analysed using thematic analysis.</p> <p>Discussion</p> <p>The Personal Concerns Interview as a preparation for treatment of people with personality has the potential to maximise treatment uptake, reduce unfilled places in treatment programmes, and prevent group treatments faltering through non-attendance.

Examining the Psychopathology of Incarcerated Male Firesetters using the Millon Clinical Multiaxial Inventory-III

Research to date has been equivocal on the relationship between firesetting and psychopathology, and has been impeded by studies lacking adequate control samples. The present study examined psychopathology in a sample of incarcerated adult male firesetters (n = 112) and prison controls (n = 113) using the Millon Clinical Multiaxial Inventory-III. Firesetters demonstrated multiple elevated scores on personality and clinical syndrome scales. Logistic regression showed that the borderline personality scale was the strongest personality scale discriminator between firesetters and controls. Major depression and drug dependence were the strongest clinical syndrome scale predictors. However, both clinical syndrome scale predictors appeared to be mediated by borderline personality scores indicating that firesetters are best characterized by responding indicative of borderline personality traits rather than other psychopathological deficits. The results suggest that, relative to other offenders, firesetters face challenges with impulse control, affect regulation, stability of interpersonal relationships, and self-image

Reclaiming the humanity in personality Disorder.

This paper provides a commentary upon the nursing care of individuals diagnosed with personality disorder and associated education courses. The discussion focuses upon recent policy trends in the UK as a point of departure. This policy discourse is critical of mainstream mental health services in previously operating to exclude such individuals. One of the consequences has been a recent growth in interest in relevant training courses, many of which devote significant attention to staff attitudes regarding this client group. Various previous researchers and commentators have remarked upon the implications for practice of a perceived negative attitude among care staff. We reflect upon our own anecdotal experience of developing and delivering new university-based courses for practitioners working in the field of personality disorder to offer a particular critique of the UK context, in which this policy, training, and practice is framed. Social constructionist theories are drawn on to offer insights into public and practitioner discourse and the possible effects on therapeutic relationships. The available discourse constructs individuals with a diagnosis of personality disorder as essentially different from other people. We argue that staff training and practice development initiatives are likely to be more successful if such discourse is challenged, and attempts are made in therapeutic encounters to recognize shared characteristics and positive attributes as much as perceived difference and negative attributes. We refer to this as a re-engagement with common humanity. Despite the singular national context, the discursive themes explored are not necessarily restricted to the UK
