Abstract
BACKGROUND Women who use or are in treatment for drug use during the perinatal period often have complex needs and presenting comorbidity. Women who use opioids during pregnancy, and their infants, experience poor outcomes. Drug use by women during pregnancy is a public health priority. This scoping review aimed to (1) map clinical guidelines, treatment protocols and good practice guidance across the UK for women who use or are in treatment for drug use during the perinatal period, (2) identify recommended best practice across health and social care for optimising outcomes and reducing inequalities for these women and (3) identify potential gaps within guidance. METHODS We followed the Joanna Briggs International (JBI) guidance on scoping reviews and PRISMA Scr extension. A registered protocol, containing a clear search strategy, inclusion, and exclusion criteria was adhered to. Reviewers double screened 25%, discussing disagreements. Data were extracted using a predefined template and charted in tables. Recommendations for best practice were organised around agreed categories. RESULTS Of 968 documents screened, 111 met the inclusion criteria. The documents included UK-wide, national, regional, and organisational policy documents. They varied in the degree they were relevant to women who use or are in treatment for drug use during the perinatal period, the settings to which they applied, and their intended users. Most were created without patient or public involvement and lacked any clear evidence base. Overall, documents recommended an integrated model of care with a lead professional, clear referral pathways and information sharing between agencies. Guidance suggested referrals should be made to specialist midwives, drug, and social care services. A holistic assessment, inclusive of fathers / partners was suggested. Recent documents advocated a trauma-informed care approach. Opioid substitution therapy (OST) was recommended throughout pregnancy where required. Potential gaps were identified around provision of support for women postnatally, especially when their baby is removed from their care. CONCLUSIONS This synthesis of recommended practice provides key information for practitioners, service providers and policy makers. It also highlights the need for guidelines to be evidence-based, informed by the experiences of women who use or are in treatment for drug use during the perinatal period, and to address the support needs of postnatal women who have their babies removed from their care.

Abstract
Introduction COVID-19 restrictions created barriers to "business as usual" in healthcare but also opened the door to innovation driven by necessity. This manuscript (1) describes how ADVANCE, an in-person group perpetrator program to reduce intimate partner violence (IPV) against female (ex)partners by men in substance use treatment, was adapted for digitally-supported delivery (ADVANCE-D), and (2) explores the feasibility and acceptability of delivering ADVANCE-D to men receiving substance use treatment. Methods Firstly, the person-based approach and mHealth development framework were used to iteratively adapt ADVANCE for digitally-supported delivery including conceptualization, formative research, and pre-testing. Then, a non-randomized feasibility study was conducted to assess male participants' eligibility, recruitment, and attendance rates and uptake of support offered to their (ex)partners. Exploratory analyses on reductions in IPV perpetration (assessed using the Abusive Behavior Inventory; ABI) and victimization (using the revised ABI; ABI-R) at the end of the program were performed. Longitudinal qualitative interviews with participants, their (ex)partners, and staff provided an understanding of the program's implementation, acceptability, and outcomes. Results The adapted ADVANCE-D program includes one goal-setting session, seven online groups, 12 self-directed website sessions, and 12 coaching calls. ADVANCE-D includes enhanced risk management and support for (ex)partners. Forty-five participants who had perpetrated IPV in the past 12 months were recruited, forty of whom were offered ADVANCE-D, attending 11.4 (SD 9.1) sessions on average. Twenty-one (ex)partners were recruited, 13 of whom accepted specialist support. Reductions in some IPV perpetration and victimization outcome measures were reported by the 25 participants and 11 (ex)partners interviewed pre and post-program, respectively. Twenty-two participants, 11 (ex)partners, 12 facilitators, and 7 integrated support service workers were interviewed at least once about their experiences of participation. Overall, the program content was well-received. Some participants and facilitators believed digital sessions offered increased accessibility. Conclusion The digitally-supported delivery of ADVANCE-D was feasible and acceptable. Remote delivery has applicability post-pandemic, providing greater flexibility and access. Given the small sample size and study design, we do not know if reductions in IPV were due to ADVANCE-D, time, participant factors, or chance. More research is needed before conclusions can be made about the efficacy of ADVANCE-D.

Abstract
BACKGROUND The prevalence of drug use in Muslim communities is difficult to estimate due to religious, social, and cultural prohibition toward drug use. With Islam affecting all aspects of life in the Muslim world, people who use drugs do it clandestinely to avoid stigma and exclusion from the community, leading to a low number of them seeking treatment for their drug use. This review explored the barriers and facilitators to accessing inpatient and community substance use treatment and harm reduction services for people who use drugs in Muslim communities. METHODS This review was in accordance with PRISMA. Seven databases were systematically searched for qualitative, quantitative, and mixed methods studies conducted in countries where at least 70% of the population were Muslim or where data were presented separately for Muslim communities in other countries. Eligible articles were reviewed, and key qualitative themes were abstracted and compared across studies and settings. RESULTS Twenty-four studies were included from Iran, Bangladesh, Afghanistan, Tajikistan, Kazakhstan, Kyrgyzstan, Egypt, Lebanon, and UAE. Two themes were identified: a psychosocial theme included denial of the problem severity, lack of trust in the treatment system, fear of breach in confidentiality and privacy, the need for community support, religion and women who use drugs. Additionally, an organizational theme included affordability, treatment Service characteristics, lack of Awareness, service providers' Attitudes, drug use registration and fear of legal consequences of drug use. Stigma was also identified as an over-arching theme. The Mixed Methods Appraisal Tool (MMAT) was used to assess the quality of the included studies with where 12 of the studies met all 5 the quality criteria. No studies were excluded for having lower quality scores. CONCLUSION This review reflected how diverse the Muslim world is in drug use. It is important to use mosques to raise awareness on people who use drugs and reduce stigma. Providing holistic services for people who use drugs specially women will improve their access to treatment and harm reduction services in the Muslim world.

Abstract
Despite consistent evidence that substance use is a contributory risk factor for perpetration of intimate partner abuse (IPA), little evidence exists for effective interventions for male IPA perpetrators who use substances. The Advance intervention aimed to meet this need. This 16-week intervention addressed both IPA and substance use, and was for men accessing substance use treatment who had perpetrated IPA toward a female (ex-)partner within the last 12 months. Two key theories underpinned the intervention: goal theory and self-regulation theory. In this article, we aim to illustrate the views of men and substance use treatment staff on men's motivations to change, the ways in which men and staff said that men had changed their behavior, and the aspects of the intervention that they reported were key in the process of change. Using framework analysis, we analyzed data from 12 men who took part in the intervention as well as 31 staff members from substance use treatment services. Our five overarching themes were personal goal setting and motivation; recognition of IPA and the substance using lifestyle; improved self-regulation; considering the impact on others; and learning together in a group. Men and staff valued having a program that integrated IPA and substance use and thought the program was unique and much needed. Moreover, our findings suggest that goal theory, self-regulation, and more broadly, motivational and strengths-based approaches with practice-based activities, may be beneficial for effecting change in the substance using perpetrator population. However, further research is needed to determine the effectiveness of the intervention. Overall, our findings highlight the value of using qualitative outcome measures of perpetrator programs to complement quantitative measures of impact.

Abstract
BACKGROUND Compared to men in the general population, men in substance use treatment are more likely to perpetrate intimate partner abuse (IPA). The ADVANCE group intervention for men in substance use treatment is tailored to address substance use and IPA in an integrated way. In a feasibility trial pre-COVID, men who received the ADVANCE intervention via face-to-face group delivery showed reductions in IPA perpetration. Due to COVID-19, ADVANCE was adapted for remote digital delivery. METHODS/DESIGN This mixed-methods non-randomised feasibility study, with a nested process evaluation, will explore the feasibility and acceptability of delivering the ADVANCE digital intervention to men in substance use treatment who have perpetrated IPA towards a female partner in the past year. Sixty men will be recruited from seven substance use treatment services in Great Britain. The ADVANCE digital intervention comprises a preparatory one-to-one session with a facilitator to set goals, develop a personal safety plan, and increase motivation and a preparatory online group to prepare men for taking part in the intervention. The core intervention comprises six fortnightly online group sessions and 12 weekly self-directed website sessions to recap and practise skills learned in the online group sessions. Each website session is followed by a one-to-one video/phone coaching session with a facilitator. Men will also receive their usual substance use treatment. Men's female (ex) partners will be invited to provide outcome data and offered support from integrated safety services (ISS). Outcome measures for men and women will be sought post intervention (approximately 4 months post male baseline interview). Feasibility parameters to be estimated include eligibility, suitability, consent, recruitment, attendance, retention and follow-up rates. In-depth interviews or focus groups will explore the intervention's acceptability to participants, facilitators and ISS workers. A secondary focus of the study will estimate pre-post-differences in outcome measures covering substance use, IPA, mental health, self-management, health and social care service use, criminal justice contacts and quality of life. DISCUSSION Findings will inform the design of a multicentre randomised controlled trial evaluating the efficacy and cost-effectiveness of the ADVANCE digital intervention for reducing IPA. TRIAL REGISTRATION The feasibility study was prospectively registered: ISRCTN66619273 .

Abstract
Few studies have examined intimate partner violence (IPV) in relationships where one or both partners are in treatment for substance use, from the perspectives of both members of a couple. This study used thematic and narrative analysis of the accounts of 14 men recruited from substance use services and 14 women who were their current or former intimate partners. Separate researchers interviewed men and women from the same dyad pair. The psychopharmacological effects of substance use (including intoxication, craving, and withdrawal) were rarely the only explanation offered for IPV. Violence was reported to be primed and entangled with sexual jealousy, with perceptions of female impropriety and with women's opposition to male authority. Both partners reported adversities and psychological vulnerabilities that they considered relevant to conflict and abuse. Male participants were more likely to describe IPV as uncharacteristic isolated events that arose from specific disputes-either aggravated by intoxication or withdrawal or about substance use and its resourcing-whereas women described enduring patterns of abusive behavior often linked to intoxication, craving, withdrawal, and to disputes linked to raising funds for substances. In relationships where both partners used substances, men described the need to protect their partners from addiction and from unscrupulous others while women described highly controlling behavior. In relationships where women were not dependent substance users, they reported the combined effects of psychological and financial abuse often linked to recurring patterns of substance use and relapse. These findings highlight the challenges faced by practitioners working with male perpetrators who use substances as well as the need of those working with women who have been abused to engage with the ways in which hesitance to leave male abusers can be complicated by shared drug dependency.

Abstract
BACKGROUND Substance use is a risk factor for intimate partner abuse (IPA) perpetration. Delivering perpetrator interventions concurrently with substance use treatment shows promise. METHODS The feasibility of conducting an efficacy and cost-effectiveness trial of the ADVANCE 16-week intervention to reduce IPA by men in substance use treatment was explored. A multicentre, parallel group individually randomised controlled feasibility trial and formative evaluation was conducted. Over three temporal cycles, 104 men who had perpetrated IPA towards a female (ex) partner in the past year were randomly allocated to receive the ADVANCE intervention + substance use treatment as usual (TAU) (n = 54) or TAU only (n = 50) and assessed 16-weeks post-randomisation. Participants' (ex) partners were offered support and 27 provided outcome data. Thirty-one staff and 12 men who attended the intervention participated in focus groups or interviews that were analysed using the framework approach. Pre-specified criteria assessed the feasibility of progression to a definitive trial: 1) ≥ 60% of eligible male participants recruited; 2) intervention acceptable to staff and male participants; 3) ≥ 70% of participants followed-up and 4) levels of substance use and 5) IPA perpetrated by men in the intervention arm did not increase from average baseline level at 16-weeks post-randomisation. RESULTS 70.7% (104/147) of eligible men were recruited. The formative evaluation confirmed the intervention's acceptability. Therapeutic alliance and session satisfaction were rated highly. The overall median rate of intervention session attendance (of 14 compulsory sessions) was 28.6% (range 14.3-64.3% by the third cycle). 49.0% (51/104) of men and 63.0% (17/27) of their (ex) partners were followed-up 16-weeks post-randomisation. This increased to 100% of men and women by cycle three. At follow-up, neither substance use nor IPA perpetration had worsened for men in the intervention arm. CONCLUSIONS It was feasible to deliver the ADVANCE intervention in substance use treatment services, although it proved difficult to collect data from female (ex)partners. While some progression criteria were met, others were not, although improvements were demonstrated by the third cycle. Lessons learned will be implemented into the study design for a definitive trial of the ADVANCE intervention. TRIAL REGISTRATION ISRCTN79435190 prospectively registered 22nd May 2018.

Abstract
Despite the high prevalence of intimate partner violence (IPV) perpetration by men receiving substance use treatment, little is known about their help-seeking behaviors for IPV. A secondary analysis of a mixed-methods study of men receiving substance use treatment who perpetrated IPV examined the prevalence, characteristics, and barriers associated with IPV perpetration disclosure and help-seeking. In total, 170 men were interviewed using a structured questionnaire, and a subsample of 20 were interviewed in-depth about their experiences. Logistic regression determined variables associated with disclosure and help-seeking. Thematic analysis of the in-depth interviews explored barriers to disclosure and help-seeking. Only half the participants had told anyone about their IPV perpetration and about one quarter reported having sought any sort of support. Whereas participants were more likely to disclose their IPV perpetration to informal resources (such as friends or family), they tended to seek help from formal resources (such as health professionals or the police). A greater proportion of physical IPV perpetrators, who had disclosed, had been arrested or had police involvement for IPV, suggesting that their disclosure may not have been voluntary. The following themes emerged from the qualitative data about the barriers to disclosure and help-seeking for IPV perpetration: fear that their children would be taken into care by social services, shame and embarrassment, and a minimization or normalization of their behavior. In addition, many participants highlighted that they had never been previously asked about IPV during treatment for substance use and stressed the need for greater expertise in or knowledge of this topic from specialist services. Substance use treatment services should enquire about men's relationships and IPV perpetration to facilitate disclosure and provide support. Further research is necessary to determine the context of disclosure and help-seeking for IPV perpetration to increase the likelihood of identification.

Abstract
Undertaking qualitative dyad or couple interviews involving intimate partner abuse and substance use presents considerable ethical, safeguarding, and theoretical challenges throughout the research process from recruitment to conducting interviews and analysis. These challenges and how they were managed are outlined using the experience from a qualitative study of 14 heterosexual "couples" that explored the complex interplay between intimate partner abuse and substance use. Managing these challenges for participants, their families, and researchers included the use of safeguarding protocols and procedures to manage risk and the provision of clinical support for experienced researchers. Researchers often felt drawn into the conflicts and complex dynamics of opposing accounts from the male and females' relationship which could be emotionally and methodologically taxing. Researchers discussing their analysis and felt experiences with each other provided a reflexive space to manage emotions and stay close to the theoretical underpinnings.

Abstract
BACKGROUND Strong evidence exists that substance use is a contributory risk factor for intimate partner abuse (IPA) perpetration. Men in substance use treatment are more likely to perpetrate IPA than men from the general population. Despite this, referral pathways are lacking for this group. This trial will assess the feasibility of conducting an evaluation trial of a tailored integrated intervention to address substance use and IPA perpetration to men in substance use treatment. METHODS/DESIGN ADVANCE is a multicentre, parallel-group individually randomised controlled feasibility trial, with a nested formative evaluation, comparing an integrated intervention to reduce IPA + substance use treatment as usual (TAU) to TAU only. One hundred and eight men who have perpetrated IPA in the past 12 months from community substance use treatment in London, the West Midlands, and the South West will be recruited. ADVANCE is a manualised intervention comprising 2-4 individual sessions (2 compulsory) with a keyworker to set goals, develop a personal safety plan and increase motivation and readiness, followed by a 12-session weekly group intervention delivered in substance use services. Men will be randomly allocated (ratio 1:1) to receive the ADVANCE intervention + TAU or TAU only. Men's female (ex) partners will be invited to provide outcome data and offered support from integrated safety services (ISS). Regular case management meetings between substance use and ISS will manage risk. Outcome measures will be obtained at the end of the intervention (approximately 4 months post-randomisation) for all male and female participants. The main objective of this feasibility trial is to estimate parameters required for planning a definitive trial including rates of consent, recruitment, and follow-up by site and group allocation. Nested formative evaluation including focus groups and in-depth interviews will explore the intervention's acceptability to participants, group facilitators, keyworkers and ISS workers. Secondary outcomes include substance use, IPA, mental health, self-management, health and social care service use, criminal justice contacts, and quality of life. DISCUSSION Findings from this feasibility trial will inform the design of a multicentre randomised controlled trial evaluating the efficacy and cost-effectiveness of the ADVANCE intervention for reducing IPA and improving the well-being of female (ex)partners. TRIAL REGISTRATION ISRCTN79435190.

Abstract
Purpose
It proved difficult to recruit sufficient mothers to a prospective cohort study designed to explore the factors and characteristics of mothers whose children are the subject of the public care system as a result of their drinking, retaining or losing care of their children. In conducting interviews instead with social workers in six local authorities, the repurposed study aimed to explore their views of the barriers and facilitators to involving this “hard to reach” population of mothers in research at the beginning of care proceedings.
Design/methodology/approach
For this study, 36 semi-structured telephone interviews were conducted with child and family social workers and social work managers located in six English local authorities. Transcripts were analysed using Nvivo and coded thematically.
Findings
Workforce issues and social work workload, court timescales and the additional burden that participating in research at a time of enormous stress for mothers were described as barriers to recruitment. Social workers suggested that the criteria for including participants could be widened to include mothers in pre-proceedings and that recruitment could take place via substance use services with whom mothers do not have an antagonistic relationship.
Research limitations/implications
The perspective of social work practitioners and not mothers themselves on barriers to engagement in research is a limitation of the study. Innovative and flexible research design is needed to include the participation of mothers whose alcohol use has led to court proceedings in research.
Originality/value
Few studies have investigated the barriers and facilitators to engaging mothers in research at the point that care proceedings have been issued. The re-purposed study highlighted the particular stresses on mothers and social workers and made recommendations for alternative strategies for recruiting these mothers and representing their experience in research.

Abstract
Purpose
The purpose of this paper is to examine frequency and correlates of intimate partner violence (IPV) severity perpetrated by heterosexual men receiving treatment for substance use towards a current partner in the past 12 months.
Design/methodology/approach
A secondary analysis of a self-reported questionnaire (n=162) completed by men receiving treatment for substance use in England and Brazil was conducted. Types of IPV perpetration (emotional, physical and/or sexual IPV) and frequency of occurrence were assessed. A five level ordinal variable for IPV perpetration severity was created: no IPV, minor; moderate, low severe and high severe. Psychological and cultural correlates of perpetration severity were explored using ordinal logistic regression.
Findings
Approximately four in ten men reported perpetrating IPV towards their partner in the past 12 months, one in ten reported perpetrating severe IPV (including hitting with something, kicking or beating, choking or burning, threatening with/using a weapon, sexual IPV and frequent emotional IPV) during this period. A number of correlates of perpetration severity were identified: experiencing childhood physical abuse, witnessing IPV in childhood, perpetrating IPV in previous relationships, committing violence towards another man, controlling behaviours, technology-facilitated abuse, depressive symptoms, having a substance using partner, receiving treatment for illicit drug use, hazardous drinking and poly-drug use.
Research limitations/implications
Despite the small sample size, small to large positive associations were observed between reporting IPV perpetration and several factors. These factors could be targeted to improve identification and assessment of IPV among men receiving treatment for substance use.
Originality/value
A strength of this study methodology is the use of a specific 12 months time frame for the perpetration of IPV towards current partner. The categorisation of levels of IPV perpetration based on types and frequency of violence occurrence was an additional valuable contribution of this study.

Abstract
We prove the hitherto hypothesized sequential dissociation of Fe(CO)5 in the gas phase upon photoexcitation at 266 nm via a singlet pathway with time-resolved valence and core-level photoelectron spectroscopy with an x-ray free-electron laser. Valence photoelectron spectra are used to identify free CO molecules and to determine the time constants of stepwise dissociation to Fe(CO)4 within the temporal resolution of the experiment and further to Fe(CO)3 within 3 ps. Fe 3p core-level photoelectron spectra directly reflect the singlet spin state of the Fe center in Fe(CO)5, Fe(CO)4, and Fe(CO)3 showing that the dissociation exclusively occurs along a singlet pathway without triplet-state contribution. Our results are important for assessing intra- and intermolecular relaxation processes in the photodissociation dynamics of the prototypical Fe(CO)5 complex in the gas phase and in solution, and they establish time-resolved core-level photoelectron spectroscopy as a powerful tool for determining the multiplicity of transition metals in photochemical reactions of coordination complexes.

Abstract
Introduction and Aims Controlling behaviours are highly prevalent forms of non‐physical intimate partner violence (IPV). The prevalence of perpetrating controlling behaviours and technology‐facilitated abuse (TFA) was compared by men receiving substance use treatment in England (n = 223) and Brazil (n = 280). Factors associated with perpetrating these behaviours towards their current/most recent partner and their association with other types of IPV were explored. Design and Methods Secondary analysis from two cross‐sectional studies was performed. Data on socio‐demographic characteristics, infidelity, IPV perpetration and victimisation, adverse childhood experiences (ACE), attitudes towards gender relations and roles, substance use, depressive symptoms and anger expression were collected. Results Sixty‐four percent (143/223) and 33% (73/223) of participants in England and 65% (184/280) and 20% (57/280) in Brazil reported controlling behaviours and TFA, respectively, during their current/most recent relationship. Excluding IPV victimisation from the multivariate models; perpetrating controlling behaviours was associated with a higher number of ACE, higher anger expression (England) and severe physical IPV perpetration (Brazil), and perpetrating TFA was associated with younger age. Including both IPV victimisation and perpetration in the multivariate models; perpetrating controlling behaviour was associated with experiencing a higher number of ACE, higher anger expression (England), emotional IPV victimisation (England) and experiencing controlling behaviour from a partner (England). The perpetration of TFA was associated with younger age and experiencing TFA from a partner. Conclusions Technological progress provides opportunities for perpetrators to control and abuse their partners. Controlling behaviours and TFA should be addressed to reduce IPV perpetration by males in substance use treatment. [Gilchrist G, Canfield M,Radcliffe P, d'Oliveira AFPL.

Abstract
This article reviews the literature on the factors associated with mothers who use substances losing care of their children. A rapid evidence assessment was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta Analyses. Medline and PsycINFO databases were searched to identify primary research studies published in English during January 2000-September 2016. Studies were included if they presented individual, formal support (e.g., receiving substance use treatment) or informal support (e.g., receiving social and family support) factors associated with mothers who use substances retaining or losing care of their child/ren (losing care refers to child protection services placing child/ren under the custody of a family relative, foster care, child care institution, or adoption). Evaluation studies or trials of interventions were excluded as were studies that focused on reunification or re-entering care as the outcome. Thirteen studies were included. Factors associated with mothers who use substances losing care of their children included: maternal characteristics (low socioeconomic status, younger age of first child, criminal justice involvement); psychological factors (mental health co-morbidity, adverse childhood experiences); patterns of substance use (use of cocaine prenatally, injection drug use); formal and informal support (not receiving treatment for substance use, fewer prenatal care visits, lack of social support). There is not enough evidence to determine the influence of substance use treatment in preventing mothers losing care of their children. Factors identified in this review provide the evidence to inform a prevention agenda and afford services the opportunity to design interventions that meet the needs of those mothers who are more likely to lose care of their children.

Abstract
Introduction and Aims This paper describes how substance use features in the accounts of intimate partner violence (IPV) perpetrators in treatment in England and Brazil. The aim of the research was to better understand cross cultural constructions of IPV perpetration amongst men in treatment for substance use. Design and Methods Semi‐structured interviews were conducted with 40 men in community substance use treatment in Sao Paolo, Brazil and London and the South East of England who had reported IPV perpetration in a questionnaire survey. A thematic, narrative analysis was carried out of men's explanations for IPV perpetration. Findings Three types of narratives were distinguished: (i) disputes, centred on substance use, that escalate to IPV perpetration; (ii) IPV perpetration that is explained by uncharacteristic loss of control, as a result of intoxication; and (iii) IPV perpetration provoked by a perceived betrayal, in which substance use is incidental. In all types of accounts hegemonic principles of male and female roles and behaviour provided a context for and make IPV perpetration explicable. Discussion and Conclusions Substance use and IPV are culturally constructed and contextually defined. Understanding the meaning‐making of substance using IPV perpetrators has implications for the treatment of both substance abuse and IPV.

Abstract
Two-color (x-ray+infrared) electron spectroscopy is used for investigating laser-assisted KLL Auger decay following 1s photoionization of atomic Ne with few-femtosecond x-ray pulses from the Linac Coherent Light Source. In an angle-resolved experiment, the overall width of the laser-modified Auger-electron spectrum and its structure change significantly as a function of the emission angle. The spectra are characterized by a strong intensity variation of the sidebands revealing a gross structure. This variation is caused, as predicted by theory, by the interference of electrons emitted at different times within the duration of one optical cycle of the infrared dressing laser, which almost coincides with the lifetime of the Ne 1s vacancy.

Abstract
Two-photon excitation of a single-photon forbidden Auger resonance has been observed and investigated using the intense extreme ultraviolet radiation from the free electron laser in Hamburg. At the wavelength 26.9 nm (46 eV) two photons promoted a 3d core electron to the outer 4d shell. The subsequent Auger decay, as well as several nonlinear above threshold ionization processes, were studied by electron spectroscopy. The experimental data are in excellent agreement with theoretical predictions and analysis of the underlying multiphoton processes.

Abstract
Metal clusters serve as model systems to study basic problems of electronic correlation. Vacuum ultraviolet light from the free-electron laser FLASH ionizes 5d electrons from mass-separated negatively charged clusters, thus transiently leading to core-ionized neutral systems. Shielding of the core hole affects the electron binding energy. From the strong deviation from expectations of the metallic droplet and jellium models we conclude on reduced electronic shielding once the cluster size falls below about 20 atoms. This suggests a metal-to-nonmetal transition, in agreement with previous local density approximation calculations.

Abstract
We report the creation of solid-density aluminum plasma using free-electron laser (FEL) radiation at 13.5nm wavelength. Ultrashort pulses were focused on a bulk Al target, yielding an intensity of 2x10;{14}Wcm;{2} . The radiation emitted from the plasma was measured using an xuv spectrometer. Bremsstrahlung and line intensity ratios yield consistent electron temperatures of about 38eV , supported by radiation hydrodynamics simulations. This shows that xuv FELs heat up plasmas volumetrically and homogeneously at warm-dense-matter conditions, which are accurately characterized by xuv spectroscopy.

Abstract
Two-color multiphoton ionization of atomic helium was investigated by combining extreme ultraviolet (XUV) radiation from the Free Electron Laser in Hamburg with an intense synchronized optical laser. In the photoelectron spectrum, lines associated with direct ionization and above-threshold ionization show strong variations of their amplitudes as a function of both the intensity of the optical dressing field and the relative orientation of the linear polarization vectors of the two fields. The polarization dependence provides direct insight into the symmetry of the outgoing electrons in above-threshold ionization. In the high field regime, the monochromaticity of the XUV radiation enables the unperturbed observation of nonlinear processes in the optical field.

Abstract
Background Early exit (drop-out) from drug treatment can mean that drug users do not derive the full benefits that treatment potentially offers. Additionally, it may mean that scarce treatment resources are used inefficiently. Understanding the factors that lead to early exit from treatment should enable services to operate more effectively and better reduce drug related harm. To date, few studies have focused on drop-out during the initial, engagement phase of treatment. This paper describes a mixed method study of early exit from English drug treatment services. Methods Quantitative data (n = 2,624) was derived from three English drug action team areas; two metropolitan and one provincial. Hierarchical linear modelling (HLM) was used to investigate predictors of early-exit while controlling for differences between agencies. Qualitative interviews were conducted with 53 ex-clients and 16 members of staff from 10 agencies in these areas to explore their perspectives on early exit, its determinants and, how services could be improved. Results Almost a quarter of the quantitative sample (24.5%) dropped out between assessment and 30 days in treatment. Predictors of early exit were: being younger; being homeless; and not being a current injector. Age and injection status were both consistently associated with exit between assessment and treatment entry. Those who were not in substitution treatment were significantly more likely to leave treatment at this stage. There were substantial variations between agencies, which point to the importance of system factors. Qualitative analysis identified several potential ways to improve services. Perceived problems included: opening hours; the service setting; under-utilisation of motivational enhancement techniques; lack of clarity about expectations; lengthy, repetitive assessment procedures; constrained treatment choices; low initial dosing of opioid substitution treatment; and the routine requirement of supervised consumption of methadone. Conclusion Early exit diminishes the contribution that treatment may make to the reduction of drug related harm. This paper identifies characteristics of people most likely to drop out of treatment prematurely in English drug treatment services and highlights a range of possibilities for improving services.

Abstract
Few-photon multiple ionization of Ne and Ar atoms by strong vacuum ultraviolet laser pulses from the free-electron laser at Hamburg was investigated differentially with the Heidelberg reaction microscope. The light-intensity dependence of Ne2+ production reveals the dominance of nonsequential two-photon double ionization at intensities of I<6x10(12) W/cm2 and significant contributions of three-photon ionization as I increases. Ne2+ recoil-ion-momentum distributions suggest that two electrons absorbing "instantaneously" two photons are ejected most likely into opposite hemispheres with similar energies.

Abstract
Because of the stochastic nature of self-amplified spontaneous emission (SASE), it is crucial to measure for single pulses the spectral characteristics of ultrashort pulses from the vacuum ultraviolet free electron laser (FLASH) at DESY, Germany. To meet this particular challenge, we have employed both photon and photoelectron spectroscopy. Each FEL pulse is composed of an intense and spectrally complex fundamental, centered at a photon energy of about 38.5 eV, with a bandwidth of 0.5% accompanied by higher harmonics, each carrying an intensity of typically 0.3 to 0.6% of that of the fundamental. The correlation between the harmonics and the fundamental is in remarkable agreement with a simple statistical model of SASE FEL radiation.

Abstract
Suspensions of binary mixtures of hard-sphere poly-methylmethacrylate colloidal particles were studied at six different size ratios alpha. The main aim was to determine the range of size ratios over which the binary colloidal crystals AB2 and AB13 are stable. Combining these results with those of earlier work, we found stability of AB2 for 0.60 approximately > alpha approximately > 0.425, in good agreement with theoretical predictions by computer simulation and cell model methods. AB13 was observed for 0.62 approximately > alpha approximately > 0.485, the lower limit being significantly smaller than the theoretical prediction of about 0.525. Rough measurements of crystallization rates showed that AB2 tended to crystallize fastest at small size ratios, whereas the opposite was true for AB13. These findings should provide a guide to the optimum conditions for materials applications of these binary colloidal crystals.

Abstract
We have screened for temperature-sensitive (ts) fission yeast mutants with altered polarity (alp1-15). Genetic analysis indicates that alp2 is allelic to atb2 (one of two alpha-tubulin genes) and alp12 to nda3 (the single beta-tubulin gene). atb2(+) is nonessential, and the ts atb2 mutations we have isolated are dominant as expected. We sequenced two alleles of ts atb2 and one allele of ts nda3. In the ts atb2 mutants, the mutated residues (G246D and C356Y) are found at the longitudinal interface between alpha/beta-heterodimers, whereas in ts nda3 the mutated residue (Y422H) is situated in the domain located on the outer surface of the microtubule. The ts nda3 mutant is highly sensitive to altered gene dosage of atb2(+); overexpression of atb2(+) lowers the restrictive temperature, and, conversely, deletion rescues ts. Phenotypic analysis shows that contrary to undergoing mitotic arrest with high viability via the spindle assembly checkpoint as expected, ts nda3 mutants execute cytokinesis and septation and lose viability. Therefore, it appears that the ts nda3 mutant becomes temperature lethal because of irreversible progression through the cell cycle in the absence of activating the spindle assembly checkpoint pathway.

Abstract
Oxidative stress is thought to play an important role in the pathogenesis of Parkinson's disease (PD). Glutathione (GSH), a major cellular antioxidant, is decreased in the substantia nigra pars compacta of PD patients. The aim of the present study was to investigate whether deprenyl and its desmethyl metabolite, putative neuroprotective agents in the treatment of PD, could protect cultured rat mesencephalic neurons from cell death caused by GSH depletion due to treatment with L-buthionine-(S,R)-sulfoximine (BSO). BSO (10 microM) caused extensive cell death after 48 hr, as demonstrated by disruption of cellular integrity and release of lactate dehydrogenase into the culture medium. Both deprenyl and desmethylselegiline, at concentrations of 5 and 50 microM, significantly protected dopaminergic neurons from toxicity without preventing the BSO-induced loss in GSH. Protection was not associated with monoamine oxidase type B inhibition in that pargyline, a potent MAO inhibitor, was ineffective and pretreatment with pargyline did not prevent the protective effects of deprenyl. Protection was not associated with inhibition of dopamine uptake by deprenyl because the dopamine uptake inhibitor mazindol did not diminish BSO toxicity. The antioxidant ascorbic acid (200 microM) also protected against BSO-induced cell death, suggesting that oxidative events were involved. This study demonstrates that deprenyl and its desmethyl metabolite can diminish cell death associated with GSH depletion.

Abstract
Wild-type cells of the budding yeast Saccharbmyces cerevisiae arrest in G1 upon nutrient exhaustion. Cell cycle arrest requires the WHI2 gene since whi2 mutants continue to divide and become abnormally small as nutrients are depleted. Here we show that CLN1 and CLN2 transcript levels in a whi2 strain are higher during exponential growth, and persist longer upon starvation, than in an isogenic wild-type strain. In contrast to CLN1 and CLN2, CLN3 levels declined only at very high cell density and were unaffected by the whi2 mutation. Elevated CLN expression is sufficient to explain the whi2 phenotype since ectopic expression of CLN1 in a nutrient-depleted culture caused cells to continue dividing and interfered with the acquisition of heat resistance. These observations show that, either directly or indirectly, Whi2 negatively regulates G1 cyclin expression. Interestingly extremely high levels of Cln1 induced filamentous growth upon nutrient deprivation, suggesting a direct connection between G1 cyclin activity and morphological responses to poor nutrient conditions.

Experimentally, deprenyl has also been shown to prevent neuronal cell death in various models through a mechanism that is independent of MAO-B inhibition. We examined the effect of deprenyl on cultured mesencephalic dopamine neurons subjected to daily changes of feeding medium, an experimental paradigm that causes neuronal death associated with activation of the NMDA subtype of glutamate receptors. Both deprenyl (0.5-50 microM) and the NMDA receptor blocker MK-801 (10 microM) protected dopamine neurons from damage caused by medium changes. The nonselective MAO inhibitor pargyline (0.5-50 microM) was not protective, indicating that protection by deprenyl was not due to MAO inhibition. Deprenyl (50 microM) also protected dopamine neurons from delayed neurotoxicity caused by exposure to NMDA. Because deprenyl had no inhibitory effect on NMDA receptor binding, it is likely that deprenyl protects from events occurring downstream from activation of glutamate receptors. As excitotoxic injury has been implicated in neurodegeneration, it is possible that deprenyl exerts its beneficial effects in Parkinson's disease by suppressing excitotoxic damage.
