Abstract

Purpose

The purpose of this paper is to demonstrate a novel use of a generalized Lennard‐Jones (LJ) force law in Physicomimetics, combined with offline evolutionary learning, for the control of swarms of robots moving through obstacle fields towards a goal. The paper then extends the paradigm to demonstrate the utility of a real‐time online adaptive approach named distributed agent evolution with dynamic adaptation to local unexpected scenarios (DAEDALUS).

Design/methodology/approach

To achieve the best performance, the parameters of the force law used in the Physicomimetics approach are optimized, using an evolutionary algorithm (EA) (offline learning). A weighted fitness function is utilized consisting of three components: a penalty for collisions, lack of swarm cohesion, and robots not reaching the goal. Each robot of the swarm is then given a slightly mutated copy of the optimized force law rule set found with offline learning and the robots are introduced to a more difficult environment. The online learning framework (DAEDALUS) is used for swarm adaptation in this more difficult environment.

Findings

The novel use of the generalized LJ force law combined with an EA surpasses the prior state‐of‐the‐art in the control of swarms of robots moving through obstacle fields. In addition, the DAEDALUS framework allows the swarms of robots to not only learn and share behavioral rules in changing environments (in real time), but also to learn the proper amount of behavioral exploration that is appropriate.

Research limitations/implications

There are significant issues that arise with respect to “wall following methods” and “local minimum trap” problems. “Local minimum trap” problems have been observed in this paper, but this issue is not addressed in detail. The intention is to explore other approaches to develop more robust adaptive algorithms for online learning. It is believed that the learning of the proper amount of behavioral exploration can be accelerated.

Practical implications

In order to provide meaningful comparisons, this paper provides a more complete set of metrics than prior papers in this area. The paper examines the number of collisions between robots and obstacles, the distribution in time of the number of robots that reach the goal, and the connectivity of the formation as it moves.

Originality/value

This paper addresses the difficult task of moving a large number of robots in formation through a large number of obstacles. The important real‐world constraint of “obstructed perception” is modeled. The obstacle density is approximately three times the norm in the literature. The paper shows how concepts from population genetics can be used with swarms of agents to provide fast online adaptive learning in these challenging environments. In addition, this paper also presents a more complete set of metrics of performance.

Abstract

This chapter examines the differing ways in which the criminal responsibility of children has been understood in English and Australian common law. The doctrine of “doli incapax” has for many centuries worked to establish a presumption in law that children between the ages of around 10 and 14 are incapable of forming criminal intent, unless it can be shown that they are capable of ‘guilty knowledge’ about their actions. In this approach, children are presumed to be ‘naughty’ until it can be shown that they are ‘bad’. However, events such as the murder of James Bulger in 1993 have led to the abolition of the doctrine in the UK, and its questioning in Australia. The chapter will outline how and why the law’s distinction between adults and children in relation to crime has become unstable, and explain the implications of the legal conception of childhood for the sociology of childhood more broadly. It will also explore how a closer look at the history of the doli incapax presumption sheds considerable light on the central and active role played by the judiciary and the legal profession, as opposed to other social and professional groups, in the development of a particular legal construction of childhood.

Abstract

Investigates the differences in protocols between arbitral tribunals and courts, with particular emphasis on US, Greek and English law. Gives examples of each country and its way of using the law in specific circumstances, and shows the variations therein. Sums up that arbitration is much the better way to gok as it avoids delays and expenses, plus the vexation/frustration of normal litigation. Concludes that the US and Greek constitutions and common law tradition in England appear to allow involved parties to choose their own judge, who can thus be an arbitrator. Discusses e‐commerce and speculates on this for the future.

Abstract

Purpose

The purpose of this paper is to expose practical and theoretical problems with the range of reasonable responses (RORR) test as applied in UK unfair dismissal law, and to propose an alternative interpretation of the test that would resolve these problems.

Design/methodology/approach

Through a close analysis of the purpose and structure of UK unfair dismissal law, and a careful reading of the leading cases in the area, the paper questions whether the law as it is currently interpreted achieves the goals of the underlying legislation. The current interpretation of the law being found lacking, alternatives are considered and evaluated.

Findings

The RORR test, as delineated in the most recent Court of Appeal cases, holds that dismissals are fair unless they are based on a reason for which no reasonable employer would dismiss. This interpretation of the test is internally incoherent; moreover, it fails adequately to promote the goals of unfair dismissal law, which are to protect the dignity and autonomy of employees. An alternative and superior interpretation of the test would hold a dismissal to be outside the RORR if no rational theory of management would condone dismissal on the grounds given by the employer.

Social implications

The paper draws attention to fundamental incoherence in the current interpretation and application of unfair dismissal law, and suggests a new and better approach. If the new approach were accepted by the courts or by Parliament, it could lead to reform in unfair dismissal law.

Originality/value

The paper provides a detailed analysis of the RORR test, a long‐standing and well‐recognized problem in UK unfair dismissal law, and suggests a novel solution that would improve the coherence and function of unfair dismissal law.

Abstract

Purpose

There has been controversy about whether Adam Smith is an economic egalitarian because he expresses at least four distinct views on equality, in two of which, he approves of inequality, and in the other two, he claims otherwise. The purpose of this paper is to isolate and consider these four views carefully to understand Smith’s complete position on equality.

Design/methodology/approach

The paper examines Smith’s apparently contradictory views on equality as his evolving response to Hume and Rousseau’s critiques of inequality.

Findings

Hume and Rousseau criticize any income inequality that is disproportionate to industry between the rich and poor. Smith’s response to their critiques evolves over time. In his initial response in early writings, he defends inequality in a civilized society by comparing it with a poor primitive society. However, in his later response in The Wealth of Nations, he eventually accepts Hume and Rousseau’s critiques of inequality. According to Smith, an equal and opulent society will evolve. A primitive society is equal but poor. In contrast, an existing civilized society is opulent but unequal. In each society, equality and opulence are incompatible. However, Smith believes that a future civilized society will fully achieve both equality and opulence.

Originality/value

The paper analyses both historically and theoretically the comprehensive structure of Smith’s egalitarian views.

Abstract

This article explores the neglected issue of the overrepresentation in the child protection system of children from ethnic, cultural, religious, racial, and linguistic minorities. It focuses on the accommodation of children’s diverse backgrounds within the s 31(2) threshold and s1 “best interests” stages of intervention under the Children Act 1989. First, it introduces the ethnic child protection penalty as a new tool for capturing the complex nature of overrepresentation of these children. Second, it proposes a framework for understanding the judicial approach in higher court decisions on the current extent and nature of accommodation. Third, it employs the penalty concept to help explain why case law analysis reveals difficulties with the current factor-based approach, whereas empirical research suggests generally satisfactory accommodation in practice. It concludes by proposing a contextualized framework for decision-making in relation to child protection.

Abstract

This paper considers the rules of English law which apply to fix financial intermediaries and their advisers with liability for handling the proceeds of crime. Consideration of this topic falls into two distinct parts. This paper looks at responsibility in civil law, including liability for breach of contract; liability as constructive trustee; liability for money had and received; equitable tracing and other liabilities. It then examines issues of criminal responsibility, and closes with consideration of an anomaly.

Abstract

The Applicant in this case, The Burns Anderson Independent Network plc, was authorised to conduct investment business under the Financial Services Act 1986, by virtue of its membership of the Personal Investment Authority (PIA). An allegation had been made to the PIA ombudsman that the Applicant was involved in the operation of a holiday time share business known as the Villa Investment Plan. An action group of dissatisfied time share purchasers from the Villa Investment Plan was formed and lodged a complaint with the PIA ombudsman claiming compensation for losses amounting to £8m.
