Abstract

Purpose

Evaluations of the impact of case formulation on outcomes for offenders are needed. The quality of case formulations may impact on outcomes, hence one essential aspect in outcome evaluation is quality assessment. A case formulation quality checklist (CFQC) was constructed and showed good reliability and internal consistency. However, feedback from users was the CFCQ could be improved. The purpose of this paper is to ascertain the opinions of professionals who had used the CFQC to provide a basis for its revision.

Design/methodology/approach

This was a qualitative study, in which ten professionals who had used the CFQC were asked their views about it. An inductive thematic analysis was used to organise the data.

Findings

Seven themes were identified. First, the importance of assessing quality in case formulation; second, the appropriate and comprehensive content of the CFQC; third, the practicality of the CFQC; fourth, validity and reliability issues; fifth, ways to improve the CFQC; sixth, potential as a training tool; seventh, limitations of the use of the CFQC. The CFQC was revised in light of these comments, producing the CFQC-R.

Research limitations/implications

The reliability and consistency of the CFQC-R needs to be examined, as does validity, particularly predictive validity. This information will better enable research into whether case formulation improves outcomes for service users, and whether better quality case formulations lead to greater improvements.

Practical implications

The CFQC-R may be of value in training and supervising clinicians in constructing case formulations.

Originality/value

The CFQC-R is reproduced here so that researchers and practitioners may use the checklist.

Abstract

Purpose

The purpose of this paper is to investigate the use of multidisciplinary optimization (MDO) formulations within space‐mapping techniques in order to reduce their computing time.

Design/methodology/approach

The aim of this work is to quantify the interest of using MDO formulations within space mapping techniques. A comparison of three MDO formulations is carried out in a short time by using an analytical model of a safety transformer. This comparison reveals the advantage of two formulations in terms of robustness and computing time among the three MDO formulations. Then, the best formulations are investigated within output space mapping, using both analytical and FE models of the transformer.

Findings

A major computing time gain equal to 5.5 is achieved using the Individual Disciplinary Feasibility formulation within the output space‐mapping technique in the case of the safety transformer.

Originality/value

The MultiDisciplinary Feasibility formulation is the common formulation used within space‐mapping technique because it is the most conventional way to perform MDO. The originality of this paper is to investigate the Individual Disciplinary Feasibility formulation within output space‐mapping technique in order to allow the parallelization of calculation and to achieve a major reduction of computing time.

Abstract

Purpose

This paper aims to introduce an alternative for modeling levitation forces between NdFeB magnets and bulks of high-temperature superconductors (HTS). The presented approach should be evaluated through two different formulations and compared with experimental results.

Design/methodology/approach

The T-A and H-ϕ formulations are among the most efficient approaches for modeling superconducting materials. COMSOL Multiphysics was used to apply them to magnetic levitation models and predict the forces involved.The permanent magnet movement is modeled by combining moving meshes and magnetic field identity pairs in both 2D and 3D studies.

Findings

It is shown that it is possible to use the homogenization technique for the T-A formulation in 3D models combined with mixed formulation boundaries and moving meshes to simulate the whole device’s geometry.

Research limitations/implications

The case studies are limited to the formulations’ implementation and a brief assessment regarding degrees of freedom. The intent is to make the simulation straightforward rather than establish a benchmark.

Originality/value

The H-ϕ formulation considers the HTS bulk domain as isotropic, whereas the T-A formulation homogenization approach treats it as anisotropic. The originality of the paper lies in contrasting these different modeling approaches while incorporating the external magnetic field movement by means of the Lagrangian–Eulerian method.

Surging global natural disasters provide incentive for risk-reducing policies and strategies. In this light, the African Union (AU) engaged a multi-stakeholder policy formulation

Abstract

Surging global natural disasters provide incentive for risk-reducing policies and strategies. In this light, the African Union (AU) engaged a multi-stakeholder policy formulation process between 2002 and 2006, to develop a continent-wide disaster risk reduction (DRR) strategy. Drawing from secondary data, this chapter assesses the process and applies qualitative analysis instruments to critically assess the AU’s disaster policy. Linkages to the 2005 international Hyogo Framework for Action (HFA) are also highlighted. The analysis reveals that Africa’s policy formulation process was belated for over a decade, with respect to international expectations. The formulation process was however largely African owned and led, culminating in a strategy document that reflected African contextual reality at the time, and aligned well with HFA fundamental goals. The applied multi-stakeholder approach enhanced a spirit of participation across levels and was central to the largely successful policy formulation process. However, targeted policy outcomes were not explicit, and poorly formulated indicators marred short- and long-term policy evaluation. Based on these results, we conclude that the African-wide DRR policy formulation processes were belated but participatory, systematic and very successful. Belated policy formulation reflects an initial inertia on the African continent, justified by past negative policy experiences and the desire to succeed. A replication of this policy formulation approach in Africa is recommended, albeit exercising more caution on policy timing, the elaboration of better monitoring and evaluation instruments and criteria. Participation should further embrace modern, risk-free (anti-COVID-19-friendly) information and communication technologies.

The purpose of this paper is to review the evidence base for the use of risk formulation in forensic practice settings.

Abstract

Purpose

The purpose of this paper is to review the evidence base for the use of risk formulation in forensic practice settings.

Design/methodology/approach

Systematic literature review principles were adopted to identify literature exploring risk formulation in forensic practice settings in relation to offending behaviour.

Findings

Data were analysed using a narrative synthesis approach, and commonalities were observed across some of the studies in terms of definitions, outcomes, and implementation, of risk formulation; however, the findings of the review did not provide a definitive account of risk formulation practice in forensic settings. This is due to the narrow scope of the included studies, the small yet diverse samples, the heterogeneity in research aims and the methodological weaknesses apparent within the included studies.

Research limitations/implications

Further research is needed to understand the application and outcomes of risk formulation in forensic practice settings.

Practical implications

Practitioners should be clear about how they are defining, implementing and assessing the outcomes of risk formulation, alongside being mindful of the evidence base when utilising forensic risk formulation in practice.

Originality/value

To the best of the authors’ knowledge, this is the first paper to focus solely on the evidence base for forensic risk formulation in practice.

The purpose of this paper is to evaluate pre- and post-formulation findings with multi-disciplinary staff within two secure children’s homes (SCHs) in the North East of England.

Abstract

Purpose

The purpose of this paper is to evaluate pre- and post-formulation findings with multi-disciplinary staff within two secure children’s homes (SCHs) in the North East of England.

Design/methodology/approach

Multi-disciplinary staff teams involved in formulation across two SCHs were administered pre- and post-formulation questionnaires. The pre- and post-formulation questionnaires focused on five domains: knowledge; confidence; motivation; understanding; and satisfaction with treatment plan.

Findings

A total of 338 pre- and post-formulation questionnaires were administered across 43 formulation meetings. The highest proportion of formulation attendees were: residential staff (44%); mental health staff (17%); case managers (12%); and education staff (9%). Paired samples t-tests showed significant post-formulation improvements across all domains including: knowledge [t(337) = 22.65, p < 0.001]; confidence [t(337) = 15.12, p < 0.001]; motivation [t(337) = 8.27, p < 0.001]; understanding [t(337) = 19.13, p < 0.001]; and satisfaction [t(337) = 18.81, p < 0.001].

Research limitations/implications

The SECURE STAIRS framework has supported formulation developments across the Children and Young People’s Secure Estate. Preliminary findings within two SCHs suggest multi-disciplinary staff teams find psychologically informed formulation beneficial. Future directions are considered including future evaluation of young person involvement in formulation meetings.

Originality/value

There is a notable lack of existing research within the child and young people secure estate evaluating the impact of SECURE STAIRS trauma-informed care developments including the impact of team formulation. This paper adds to the evidence base.

Abstract

Purpose

The purpose of this paper is to present eight local elasto‐plastic beam element formulations incorporated into the corotational framework for two‐noded three‐dimensional beams. These formulations capture the warping torsional effects of open cross‐sections and are suitable for the analysis of the nonlinear buckling and post‐buckling of thin‐walled frames with generic cross‐sections. The paper highlights the similarities and discrepancies between the different local element formulations. The primary goal of this study is to compare all the local element formulations in terms of accuracy, efficiency and CPU‐running time.

Design/methodology/approach

The definition of the corotational framework for a two‐noded three‐dimensional beam element is presented, based upon the works of Battini .The definitions of the local element kinematics and displacements shape functions are developed based on both Timoshenko and Bernoulli assumptions, and considering low‐order as well as higher‐order terms in the second‐order approximation of the Green‐Lagrange strains. Element forces interpolations and generalized stress resultant vectors are then presented for both mixed‐based Timoshenko and Bernoulli formulations. Subsequently, the local internal force vector and tangent stiffness matrix are derived using the principle of virtual work for displacement‐based elements and the two‐field Hellinger‐Reissner assumed stress variational principle for mixed‐based formulations, respectively. A full comparison and assessment of the different local element models are performed by means of several numerical examples.

Findings

In this study, it is shown that the higher order elements are more accurate than the low‐order ones, and that the use of the higher order mixed‐based Bernoulli element seems to require the least number of FEs to accurately model the structural behavior, and therefore allows some reduction of the CPU time compared to the other converged solutions; where a larger number of elements are needed to efficiently discretize the structure.

Originality/value

The paper reports computation times for each model in order to assess their relative efficiency. The effect of the numbers of Gauss points along the element length and within the cross‐section are also investigated.

Abstract

Purpose

The purpose of this paper is to investigate the impact of different mathematical formulations of the problem of optimal design of electrical machines on the results obtained using a local optimization solver. The aim is to investigate the efficiency and reliability of standard local solvers when handling different mathematical formulations. This could provide guidelines for designers in practical engineering applications.

Design/methodology/approach

The paper proposes six equivalent mathematical formulations of the optimal design problem of a slotless permanent‐magnet electric rotating machine. The authors investigate the impact of these different mathematical formulations on the results obtained using a local optimization solver which is well‐known in the engineering community: MatLab's fmincon function. The paper first computationally compares the six proposed formulations with a fixed value for the number of pole pairs p, that gives continuous optimization problems, then discusses some results when p is free on three mixed‐integer formulations.

Findings

The paper shows that, even though the considered formulations are mathematically equivalent, their numerical performances are different when an optimization solver, such as the one proposed by MatLab in fmincon, is used. Thus, the designer must take care about the formulation of the design problem in order to make more efficient the use of these kind of algorithms.

Originality/value

In the context of engineering applications, one usually resorts to well known and easy to use optimization solvers. The same optimization problem can be often formulated in different ways. Furthermore, the formal description of optimization problems has an impact on the applicability and efficiency of the corresponding solution methods. This is usually not taken into account when optimization solvers are exploited. The originality of this paper is in building on the theory of reformulations in mathematical optimization to investigate and highlight the impact of formulation differences.
