Abstract

Measuring the benefits of health and life‐saving programmes is a difficult and problematic task. Nevertheless, if one wants to compare the costs and benefits of a programme using cost‐benefit analysis methodology the value of life extension and improved quality of life ought to be expressed in monetary terms. The willingness‐to‐pay approach can serve as a tool to deal practically with this task. Over the years considerable criticism of the reliability and validity of this method has appeared in the literature (for example, ). In spite of the vast criticism it seems that “methods for measuring willingness to pay are being strengthened and may soon play an important role in health services research”.

Abstract

Purpose

Substance abuse is a major public health concern, with over millions of people suffering from it worldwide. Although there is an abundance of treatment options, many of these rehabilitative trajectories are subject to “drop-out”. In addition, “drop-out” is a significant risk factor for relapse. There is an urgent demand for effective treatment, which would enable patients to reduce abuse and prevent relapse. Takiwasi is an addiction treatment centre that combines traditional Amazonian plant medicine with conventional western medicine and psychotherapy. The purpose of this paper is to explore whether socio-demographics factors, such as education level and occupation, psychiatric comorbidities and primary drug use, are associated with treatment non-completion of Ayahuasca (AYA)-assisted addiction therapy.

Design/methodology/approach

Data on the first treatment episode of 121 patients were collected from the patient database from the years 2012 to 2017. To determine whether there is an association between the variables of interest and treatment non-completion, a χ2 analysis and a logistic regression analysis were performed.

Findings

Of the 121 patients analysed, 48.2 per cent completed their treatment, whilst 51.8 per cent did not. Students compared to those who are employed showed significantly higher odds for treatment non-completion (p=0.006; OR=3.7; 95% CI=1.5–9.6). Other variables in the multivariable analysis showed no significant relationship with treatment non-completion. While several limitations restricted the study, the findings suggest that the AYA-assisted treatment in Takiwasi may benefit from additional support for patients who are students. Moreover, it is advised to conduct more long-term follow-up of patients in order to gain better insight into the outcome of treatment at an AYA-assisted treatment centre.

Originality/value

It appears that AYA-assisted therapy in a therapeutic community is a feasible type of treatment for addiction, for which further studies should elucidate the role of motivation in relation to socio-demographic factors and type of addiction in the risk of treatment non-completion.

Abstract

Purpose

The purpose of this paper is to review the reasons underlying the slow rate of progress towards developing a comprehensive policy underpinning for adult safeguarding in England and proposes long-term solutions.

Design/methodology/approach

This paper uses a model of policy change to argue that adult safeguarding has been over-reliant on case histories to define its policy problems and influence its politics, while making insufficient progress on data collection and analysis. It uses examples from the parallel discipline of public health to explore four challenges, or “problems”, relevant to the further development of the knowledge base underpinning adult safeguarding policy.

Findings

Four recommendations emerge for closing the adult safeguarding “knowledge gap”, including the development of a national research strategy for adult safeguarding. In a fifth recommendation the paper also proposes a clearer recognition of the contribution that local public health professionals can make to local adult safeguarding policy making and programme development.

Practical implications

The first four recommendations of this paper would serve as the basis for developing a national research strategy for adult safeguarding. The fifth would strengthen the contribution of local public health departments to safeguarding adults boards.

Originality/value

The author is unaware of the existence of any other review of the limitations of the adult safeguarding knowledge base as a foundation for policy making, or which proposes strategic solutions. The work is valuable for its practical proposals.

Abstract

Purpose

The purpose of this paper is to assess the feasibility of analytical models, specifically the radial basis function method, Akbari–Ganji method and Gaussian method, in conjunction with the finite element method. The aim is to examine the impact of processing parameters on temperature history.

Design/methodology/approach

Through analytical investigation and finite element simulation, this research examines the influence of processing parameters on temperature history. Simufact software with a thermomechanical approach was used for finite element simulation, while radial basis function, Akbari–Ganji and Gaussian methods were used for analytical modeling to solve the heat transfer differential equation.

Findings

The accuracy of both finite element and analytical methods was validated with about 90%. The findings revealed direct relationships between thermal conductivity (from 100 to 200), laser power (from 400 to 800 W), heat source depth (from 0.35 to 0.75) and power absorption coefficient (from 0.4 to 0.8). Increasing the values of these parameters led to higher temperature history. On the other hand, density (from 7,600 to 8,200), emission coefficient (from 0.5 to 0.7) and convective heat transfer (from 35 to 90) exhibited an inverse relationship with temperature history.

Originality/value

The application of analytical modeling, particularly the utilization of the Akbari–Ganji, radial basis functions and Gaussian methods, showcases an innovative approach to studying directed energy deposition. This analytical investigation offers an alternative to relying solely on experimental procedures, potentially saving time and resources in the optimization of DED processes.
