Abstract

Purpose

One of the main components of multi-objective, and therefore, many-objective evolutionary algorithms, is the selection mechanism. It is responsible for performing two main tasks simultaneously. First, it has to promote convergence by selecting solutions which are as close as possible to the Pareto optimal set. And second, it has to promote diversity in the solution set provided. In the current work, an exhaustive study that involves the comparison of several selection mechanisms with different features is performed. Particularly, Pareto-based and indicator-based selection schemes, which belong to well-known multi-objective optimisers, are considered. The paper aims to discuss these issues.

Design/methodology/approach

Each of those mechanisms is incorporated into a common multi-objective evolutionary algorithm framework. The main goal of the study is to measure the diversity preserved by each of those selection methods when addressing many-objective optimisation problems. The Walking Fish Group test suite, a set of optimisation problems with a scalable number of objective functions, is taken into account to perform the experimental evaluation.

Findings

The computational results highlight that the the reference-point-based selection scheme of the Non-dominated Sorting Genetic Algorithm III and a modified version of the Non-dominated Sorting Genetic Algorithm II, where the crowding distance is replaced by the Euclidean distance, are able to provide the best performance, not only in terms of diversity preservation, but also in terms of convergence.

Originality/value

The performance provided by the use of the Euclidean distance as part of the selection scheme indicates this is a promising line of research and, to the best of the knowledge, it has not been investigated yet.

Abstract

Asia's economic integration into the global system has many dimensions. It is part of the broader globalization process that has taken place over the past two decades and involves dynamics of convergence, integration, and interactions of both real and financial activities. Section 1 examines some of the recent trends in the real and financial interactions between Asia and the rest of the world and among different markets within Asia. It contains four chapters on this theme, addressing the issues of macroeconomic similarities and differences, interactions among Asian stock markets and between them and the US equity market, as well as spillovers across various types of financial markets in the region in response to shocks.

Abstract

Who will lead Ambridge in the years to come? Theories rooted in psychology and political science, when applied to family dynamics in The Archers, allow for some educated guesses. Social learning theory suggests that children who see their parents vote, run for office and participate in other civic activities are more likely to do the same in adulthood. Emma Grundy did just that when she followed in the footsteps of her father, Neil Carter, in winning a seat on the parish council. Previous research has found that birth order also can shape future leaders, with the eldest child more likely to benefit developmentally from parents' undivided attention in the early years, and also more likely to establish a hierarchy of power over younger siblings. With these factors in mind, who are the most probable contenders to lead Ambridge in the spheres of politics, business and civic affairs? The extant research points to Pip Archer, Lily Pargetter, Phoebe Aldridge and George Grundy. The unique circumstances of Ruairi Donovan's childhood suggest he may also be a formidable candidate. And, as is the case in so many contexts, one would be wise not to overlook Molly Button.

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.

Abstract

Purpose

The assessment and management of risk towards others is an integral part of clinical practice, particularly in forensic and other psychiatric settings. Version 3 of the HCR-20 is the latest version of a comprehensive set of professional guidelines based on the Structured Professional Judgement model. It is the most widely used and best validated tool available to assess risk of violence; however, clinicians perceive it as an additional task with limited clinical usefulness, which requires undergoing expensive training and takes considerable time to implement. The paper aims to discuss these issues.

Design/methodology/approach

Training was delivered to 148 clinicians to improve perceptions with regard to risk formulation and the HCR-20v3 as an effective and clinically useful tool in generating individual and robust care plans to minimise risk of violence.

Findings

Results indicated significant score increase post-training, indicating higher regard for the HCR-20 in terms of its usefulness, anticipated impact upon working, anticipated impact upon managing risk, ease of completion and perceived relevance to clinical practice. This was also consistent with qualitative feedback indicating improved risk management and care planning with reference to how learning would support respective roles. Feedback also highlighted the added value of certain aspects of the training provided, which may be useful to consider when designing HCR-20 training packages.

Research limitations/implications

This study demonstrates the importance of engaging clinicians in bespoke training on the practicalities of HCR-20 completion and the fundamentals of risk formulation.

Practical implications

This study highlights the importance of incorporating a training package for staff of all disciplines in changing perceptions of risk management tools and thus their use in the practical management of violence. The useful aspects of training may assist changing perceptions of the role that risk formulation and the HCR-20v3 play in the assessment and management of violence.

Originality/value

This research suggests that if this can be done successfully, it may lead to a change in the perception of the role that the HCR-20v3 can play in assessing risk of violence and generating meaningful management plans to reduce the future likelihood of violence.

Abstract

The recent focus on literacy in Social Studies has been on linguistic design, particularly that related to the grammar of written and spoken text. When students are expected to produce complex hybridized genres such as timelines, a focus on the teaching and learning of linguistic design is necessary but not sufficient to complete the task. Theorizations of new literacies identify five interrelated meaning making designs for text deconstruction and reproduction: linguistic, spatial, visual, gestural, and audio design. Honing in on the complexity of timelines, this paper casts a lens on the linguistic, visual, spatial, and gestural designs of three pairs of primary school aged Social Studies learners. Drawing on a functional metalanguage, we analyze the linguistic, visual, spatial, and gestural designs of their work. We also offer suggestions of their effect, and from there consider the importance of explicit instruction in text design choices for this Social Studies task. We conclude the analysis by suggesting the foci of explicit instruction for future lessons.

Abstract

Purpose

The community-managed mental health sector needs to meet growing workforce demands. Yet, limited research has explored professional development opportunities and effective recruitment and retention strategies to support sector growth. One strategy is the use of a scholarship program to increase skills and training, via a University qualification. The purpose of this paper is to explore the progress of 19 mental health scholarship students and the impact of the scholarship on career intentions.

Design/methodology/approach

A mixed-methods approach comprising scholarship applications, questionnaires and semi-structured interviews was used to explore the students’ university experiences between February 2013 and January 2015. Course convenors of the Mental Health Program were interviewed. Data were collected across three time-points over 24 months, with each collection informing the next research phase. Data analysis involved thematic analysis and descriptive statistics.

Findings

Deeper knowledge, recognition of experience, new career pathways and improved work practice were benefits. Managing time and study, and work-life balance were the greatest challenges. Completing students displayed a range of internal attributes and accessed external supports. At the time of the study, the scholarships maintained student motivation and intention to work in the sector.

Originality/value

This research provides a deeper understanding of the demographics of the sector’s workforce. Insight into the attributes of completing students was obtained. The benefits realized and the challenges faced by the scholarship recipients will inform ongoing workforce development programs for the community-managed mental health sector.
