Abstract
Purpose
The purpose of this chapter is to apply structural functional theory and the concept of “unbundling” to an analysis of the deinstitutionalization and community mental health efforts that have shaped the current mental health services environment.
Approach
We examine the original goals of the institutional movement, the arguments supporting it, and the functions of the institutions that were created. We then examine the criticisms of that approach and the success of the subsequent deinstitutionalization process, which attempted to undo this process by recreating the hospitals’ functions in community settings. Finally, we address the question of whether the critical functions of psychiatric institutions have indeed been adequately recreated.
Findings
Our overview of outcomes from this process suggests that the unbundling of state hospital functions did not yield an adequate system of care and support, and that the functions of state hospitals, including social control and incapacitation with respect to public displays of deviance were not sufficiently recreated in the community-based settings.
Social implications
The arguments for the construction of state hospitals, the critiques of those settings, and the current criticism of efforts to replace their functions are eerily similar. Actors involved in the design of mental health services should take into account the functions of existing services and the gaps between them. Consideration of the history of efforts at functional change might also serve this process well.

Abstract
Initial development of microstructurally accurate finite element models of the soldered joints of electronic surface mount components is described. These models allow for the presence of lead and tin‐rich phases and copper‐tin intermetallic layers within the joints. The effect of these features on the strain distributions within the joints is shown. These strain distributions can be used to predict fatigue lives. This is demonstrated for homogeneous solder joints for which excellent correlation was shown between predicted lives and those measured experimentally by thermal cycling of actual components.

Abstract
This paper describes work which has been conducted to estimate the magnitudes of thermal stresses developed in the solder joints of electronic components during service. Finite Element Analysis (FEA) has been employed to predict the level of stress and strain in computer simulations of joints and these predictions have been validated by experimental thermal cycling tests. Future work is outlined including the incorporation of microstructural features into the FEA models. The overall goal of this research is to predict the service lives of electronic components under various operating conditions, thus facilitating the introduction of novel components and materials.

Abstract
Purpose
The term “dual diagnosis” has been widely accepted as referring to co‐existing mental illness and substance misuse. However, it is clear from the literature that individuals with these co‐existing difficulties continue to be excluded from mainstream mental health services. The term “dual diagnosis” can be pejorative and therefore, complicate or obstruct engagement. It is argued within this paper that the association between mental illness and substance misuse (including alcohol misuse) is an intricate and often a complex relationship involving a multitude of psychosocial factors that cannot be simply explained by an individual having two co‐existing disorders. From this perspective, this paper seeks to argue that the term “dual diagnosis” should be actively de‐emphasised.
Design/methodology/approach
This paper offers a critique of “dual diagnosis” and the potential impact on access and treatment through discussion of the literature and reflections on service provision.
Findings
The paper identifies five principles termed the “5 key principles”, which support individuals with a wide spectrum of co‐existing difficulties and to counteract the stigma often associated with the term “dual diagnosis”. These collective principles allow the practitioner to consider the needs of the service user from the service user's perspective and therefore not be distracted by the perceived set of expected behaviours that are implied by the “dual diagnosis” label.
Originality/value
This paper offers a critique of the term “dual diagnosis” and explores the impact of this in terms of service users and makes practical suggestions for alternative ways of conceptualising co‐existing mental health and substance difficulties.

Abstract
Purpose
There are several lead-free solder alloys available in the industry. Over the years, the most favorable solder composition of tin-silver-copper (Sn-Ag-Cu [SAC]) has been vastly used and accepted for joining the electronic components. It is strongly believed that the silver (Ag) content has a significant impact on the solder mechanical behavior and thus solder thermal reliability performance. This paper aims to assess the mechanical response, i.e. creep response, of the SAC solder alloys with various Ag contents.
Design/methodology/approach
A three-dimensional nonlinear finite element simulation is used to investigate the thermal cyclic behavior of several SAC solder alloys with various silver percentages, including 1%, 2%, 3% and 4%. The mechanical properties of the unleaded interconnects with various Ag amounts are collected from reliable literature resources and used in the analysis accordingly. Furthermore, the solder creep behavior is examined using the two famous creep laws, namely, Garofalo’s and Anand’s models.
Findings
The nonlinear computational analysis results showed that the silver content has a great influence on the solder behavior as well as on thermal fatigue life expectancy. Specifically, solders with relatively high Ag content are expected to have lower plastic deformations and strains and thus better fatigue performance due to their higher strengths and failure resistance characteristics. However, such solders would have contrary fatigue performance in drop and shock environments and the low-Ag content solders are presumed to perform significantly better because of their higher ductility.
Originality/value
Generally, this research recommends the use of SAC solder interconnects of high silver contents, e.g. 3% and 4%, for designing electronic assemblies continuously exposed to thermal loadings and solders with relatively low Ag-content, i.e. 1% and 2%, for electronic packages under impact and shock loadings.

Abstract
Purpose
Individual Placement and Support (IPS) is an evidence-based employment model, effective in supporting individuals with severe mental health difficulties to gain competitive employment. Irish mental health policy recognises its value and IPS is being rolled out in a national programme. Employment is recognised an important contributor to mental health recovery and social inclusion. However, research on IPS has tended to focus on competitive job outcomes. The purpose of this study was to explore the non-vocational outcomes of IPS in an Irish context.
Design/methodology/approach
A qualitative research approach was used to interview participants taking part in IPS within community mental health teams. Twelve interviews were included in the data analysis process which was informed by a thematic analysis approach.
Findings
Participants experienced increased confidence and positivity, both within a work context and whilst job seeking. More purposeful time use, participation in activities and engagement with society were also experienced by those employed and those at the job search stage of IPS.
Originality/value
This study contributes to the literature about the non-vocational benefits of IPS within an Irish context, highlights the mental health recovery benefits of taking part in IPS and supports the need for ongoing development of IPS throughout mental health services in Ireland.

Abstract
The strength of annealed ZrO2/Pd diffusion bonds was found to be weakened after annealing in both air and vacuum. Annealing in air reduces the strength much faster and more severely than in vacuum. Fracture surfaces of as‐bonded joints and those annealed in air and vacuum were studied to characterise the different effects of air and vacuum on the bonded interfaces. Various sizes of precipitates and voids were observed and their distribution on the fractured surfaces was examined by light microscopy. Large precipitates and voids were found close to the edges of the specimen. It is believed that the loss of strength after annealing is an effect of these defects at the highly stressed specimen edges. Transmission and analytical electron microscopy of as‐bonded joints show that an interface layer of very fine grains about 1 micron thick was formed during the bonding process. This layer has a different crystalline structure and composition from both Pd and ZrO2. Characterisation of this layer by electron microscopy is presented in this report. The formation of such a thick interface layer is probably not a pure diffusion process, rather a diffusion and melting process. From the Pd‐Zr phase diagram, there is a range of compositions near a eutectic point where a liquid phase is possible at the bonding temperatures used (1100°C). Taking the Pd‐Zr system as a qualitatively comparable system to Pd‐ZrO2, it is deduced that, at the very beginning of the bonding, Zr and Pd diffuse into each other until the melting composition is reached. The formation of the liquid phase will promote the contact and bonding processes dramatically. This explains why strong bonding cannot be achieved at lower bonding temperatures as was reported in an earlier paper. Similar experiments on Ni/ZrO2 diffusion bonds have also been studied to identify the mechanism of bonding and to compare it with Pd/ZrO2. No reaction was observed at the interface in Ni/ZrO2. Thus the wetting mechanism is absent which explains the formation of a large amount of interface voids and the much weaker bonding strength found in Ni/ZrO2 bonds.

Abstract
Purpose
The purpose of this paper is to evaluate the use of node-link mapping (NLM) on the effectiveness of a structured treatment for dual diagnosis for men living in a low-secure environment.
Design/methodology/approach
In total, 15 participants were recruited and randomly allocated to one of two conditions. The control group, treatment as usual (TAU) or the treatment group, TAU with NLM. Outcome measures used were: a qualitative evaluation form, The Alcohol and Illegal Drugs Decisional Balance Scale and the Brief Situational Confidence Questionnaire.
Findings
Results indicate no statistically significant difference for either group on the pre- and post-treatment outcome measures used. Qualitative data indicated that those using NLM reported the intervention as useful and instructive more often.
Research limitations/implications
The results gained were only a snapshot of the intervention straight after treatment and did not take into account any long-term benefits of therapy such as substance use relapse rates. The outcome measures used may not have been properly understood by all respondents, or reflect practical change. The NLM tool may not have been used as confidently as TAU. The TAU condition needs to be reviewed to improve effectiveness, and NLM to be included to improve the accessibility. A study comparing other outcome tools needs to be completed. Training for staff using NLM may require coaching.
Originality/value
This paper has a high/low originality. It highlights a number of advantages to NLM when comparing this to TAU.

Abstract
Purpose
The importance of employment in recovery from mental health illness has led to broad recognition of the integration of employment-oriented support into mental health treatment. However, there is variation in the extent to which an employment orientation permeates healthcare services. This article explores how managers and advisors in health and welfare services in Norway function as “change agents”, who work to increase an employment orientation in mental health services.
Design/methodology/approach
The empirical material consists of 20 interviews with change agents in health and welfare organisations. They work to implement a model – individual placement and support – to integrate an employment orientation in healthcare services. The findings are analysed using the framework of “institutional work” to elucidate the strategies used by change agents.
Findings
The findings underscore a consensus on the health advantages of employment and that employment-oriented support belongs in mental health treatment. However, this concept requires further cultivation within healthcare services, with individual actors playing a key role as change agents. Depending on the stage of the various organisations in the change process and the actors’ positions within the institutional context, the actors engaged in both creative and maintenance institutional work.
Practical implications
The article´s findings are significant for how health organisations can work to achieve desired changes.
Originality/value
This article contributes to the literature on collaboration and implementation of employment-oriented practices in healthcare by directing attention to the dynamics of organisational change processes and the efforts of individual actors to promote change.
