Abstract
Purpose
The purpose of this paper is to continue studies previously reported with the primary focus of optimizing an inductor design. The potential benefits of hyperthermia for cancer therapy, particularly metastatic cancers of the prostate, may be realized by the use of targeted magnetic nanoparticles that are heated by alternating magnetic fields (AMFs).
Design/methodology/approach
To further explore the potential of this technology, a high‐throughput cell culture treatment system is needed. The AMF requirements for this research present challenges to the design and manufacture of an induction system because a high flux density field at high frequency must be created in a relatively large volume. Additional challenges are presented by the requirement that the inductor must maintain an operating temperature between 35 and 39°C with continuous duty operation for 1 h or longer. Results of simulation and design of two devices for culture samples and for in vitro tests of multiple samples in uniform field are described.
Findings
The inductor design chosen provides a uniform distribution of relatively high magnetic field strength while providing an optimal reduction in the voltage and power requirement. Through development of design and selection of magnetic concentrator, the exposure of the cell cultures to the heat generated by the inductor is minimized.
Originality/value
This method of generating uniform high AC magnetic fields in a large volume is beneficial for the study of hyperthermia in cells for a high throughput, necessary for cancer treatment research.

Abstract
Purpose
This article aims to assess the role of private nuisance as a common law tool for environmental protection, independent of the wider regulatory controls. It evaluates specific areas of the tort that are theoretically unresolved in order to ascertain the potential future role it may play before highlighting the capacity for injunctions to coerce restorative environmental justice.
Design/methodology/approach
The paper is predominately a classic doctrinal article as it is principally library-based analysing both primary sources (that both pre- and post-date the modern law reporting system) and secondary sources whilst engaging in leading academic commentary.
Findings
Nuisance developed to a point in the nineteenth century where a “theory of nuisance” emerged, which did not tolerate injury to health or the property of another. Recent judicial activity has visibly adulterated that theory: this article casts doubts on juridical restrictions regarding health and property suggesting they may not withstand the scrutiny of the Supreme Court if, and when, they are tested.
Originality/value
This paper recognises that nuisance law has a positive future in environmental protection provided that the courts are willing to embrace the historical paradigm which has served the common law in this field broadly well for hundreds of years.

Abstract
Purpose
A novel technique for control of complex physical processes based on the solution of their sufficiently accurate models is presented. The technique works with the model order reduction (MOR), which significantly accelerates the solution at a still acceptable uncertainty. Its advantages are illustrated with an example of induction brazing.
Design/methodology/approach
The complete mathematical model of the above heat treatment process is presented. Considering all relevant nonlinearities, the numerical model is reduced using the orthogonal decomposition and solved by the finite element method (FEM). It is cheap compared with classical FEM.
Findings
The proposed technique is applicable in a wide variety of linear and weakly nonlinear problems and exhibits a good degree of robustness and reliability.
Research limitations/implications
The quality of obtained results strongly depends on the temperature dependencies of material properties and degree of nonlinearities involved. In case of multiphysics problems characterized by low nonlinearities, the results of solved problems differ only negligibly from those solved on the full model, but the computation time is lower by two and more orders. Yet, however, application of the technique in problems with stronger nonlinearities was not fully evaluated.
Practical implications
The presented model and methodology of its solution may represent a basis for design of complex technologies connected with induction-based heat treatment of metal materials.
Originality/value
Proposal of a sophisticated methodology for solution of complex multiphysics problems established the MOR technology that significantly accelerates their solution at still acceptable errors.

Abstract
Purpose
The purpose of this paper is to explore and examine the impact of s.158 of the Planning Act 2008 in the UK, which awards the defence of statutory authority to developers of major infrastructure projects in private nuisance actions. The paper will assess the extent to which this provision could broaden the scope of the existing defence and consider the practical implications of the new measures.
Design/methodology/approach
The paper analyses existing case law, and the historic evolution of the UK doctrine of statutory authority, in order to assess the potential judicial approach to the defence in infrastructure planning decisions.
Findings
Although s.158 of the Planning Act 2008 appears to further broaden the opportunity for the statutory immunity defence to be used, certain historical restrictions will affect its application. In awarding the defence, the judiciary have taken into account a variety of considerations such as the specificity of the location, the inevitability of the nuisance, the effect on statutory provisions, and the bearing that negligence has on the defence. These exceptions prove that there is no such thing as “blanket immunity”, and developers may still be held responsible for their un‐neighbourly conduct.
Practical implications
The scope of the protection conferred on developers of major infrastructure projects can appear confusing and could potentially create the assumption that statutory authority will act as a total defence to any actions. Developers, and their advisers, will need to be aware of the aforementioned exceptions before seeking to rely on the statutory authority defence.
Originality/value
This paper proposes that the doctrine of statutory authority has gained a newly significant status and uses recent legislation and a comprehensive overview of the existing case law to demonstrate these findings.

Abstract
Purpose
The purpose of this paper is to compare different reduced-order models for models of control of induction brazing process. In the presented application, the problem is to reconstruct temperature at the points of interests (hot spots) from information measured at accessible places.
Design/methodology/approach
The paper describes the process of induction brazing. It presents the full field model and evaluates the possibilities for obtaining reduced models for temperature estimation. The primary attention is paid to the model based on proper orthogonal decomposition (POD).
Findings
The paper shows that for the given application, it is possible to find low-order estimator. In the examined linear case, the best estimator was created using POD reduced model together with the linear Kalman filter.
Research limitations/implications
The authors are aware of two main limitations of the presented study: material properties are considered linear, which is not a completely realistic assumption. However, if strong coupling and nonlinear material parameters are considered, the model becomes unsolvable. The process and measurement uncertainties are not considered.
Originality/value
The paper deals with POD of multi-physics 3 D application of induction brazing. The paper compares 11 different methods for temperature estimator design.

Abstract
This chapter contextualizes the interrelationships between tourism and climate change and thus provides an introduction to this volume. It commences with a brief but comprehensive overview of the key issues identified by climate change research, including an update since the 2007 report by the Intergovernmental Panel on Climate Change as well as a brief discussion of the latest rounds of climate change negotiations. The pursuing discussion is informed by these points and explores climate change's indirect and induced impacts on tourism and possible ramifications. Both of these parts highlight behavioral change as a critical factor to both adaptation and mitigation thus motivating the psychological contribution in an effort to shed light on the obstacles to behavioral change. In the concluding section, the chapter synthesizes the discussion grounded in multiple disciplines into a set of research themes that the volume subsequently begins to address.

Abstract
Purpose
This work aims to summarize literature on police recruitment and retention and how changing conditions may affect these. It uses a bucket metaphor to conceptualize and present visually how these can interact with each other and create a dynamic police staffing challenge.
Design/methodology/approach
The literature review includes more than 150 works on police recruitment and retention, organized into discussions on the demand for police, the supply of police, and how systemic and episodic changes affect each.
Findings
Existing research suggests police agencies face a threefold challenge in meeting the demand for officers: attrition is likely to increase, sources of new recruits might be decreasing, and police responsibilities are expanding. Attrition might increase because of baby‐boom generation retirements, military call‐ups, changing generational expectations of careers, budget crises, and organizational characteristics. Sources of new recruits might be decreasing because of a decrease in the qualified applicant pool, changing generational preferences in selecting careers, increased competition for persons who might qualify as police officers, expanded skill requirements for police officers, uncompetitive benefits, and many of the organizational characteristics causing attrition. Policing responsibilities are expanding because of new roles in community policing, homeland security, and emerging crimes.
Originality/value
This work summarizes, as no other has previously, the extant research on police recruitment and retention. Many holes remain in the literature, but identifying the extant literature can help identify these and possible means to fill them. Reviewing the extant literature can also help agencies identify the proper lessons to face their own recruitment and retention challenges.

Abstract
Purpose
The purpose of this paper is to analyse the nature and content of the laws relating to market abuse with a view to determining whether they only offer a civil law remedy for the State. The three categories of insider dealing as defined by the Criminal Justice Act 1993 clearly offer a criminal law based response, but as is shown here virtually all cases of market abuse can potentially be a basis for a criminal prosecution.
Design/methodology/approach
The methodology adopted is to consider the other relevant areas of law, namely the Fraud Act 2006, the law of conspiracy to defraud and the law relating to misleading communications under s.397 of the Financial Services and Markets Act 2000 and then to determine whether between them they cover all the areas of behaviour caught by the definitions of market abuse.
Findings
The consequences of this paper are that the Serious Fraud Office and the Financial Conduct Authority now have the option in almost any case of market abuse of considering whether a criminal or civil law approach is appropriate.
Originality/value
The approach adopted over the last two years by the prosecuting authorities of using the criminal law to a greater extent in serious cases of insider dealing can now be extended to market abuse generally where it is thought appropriate.

Abstract
Purpose
Nowadays, various software is available for simulating physical processes in induction heating. The software is often limited in its ability to simulate the billet movement, sometimes assuming uniform distribution of voltages on the inductor winding, uniformity of the physical properties of the billet, etc. The mathematical model of moving cylindrical ferromagnetic billets described in this paper takes into account the billet's movement, the billet phase heterogeneity and the nonuniformity of the supply voltage distribution in the inductor turns. The paper aims to discuss these issues.
Design/methodology/approach
The research methodology is based on FEM analysis of the coupled problem, including the electromagnetic and thermal boundary problem with additional algebraic equations, using Comsol 3.5a software.
Findings
The electromagnetic and temperature field in the billet and the voltage distribution on the winding turns have been calculated. The phase distribution in the billet has been predicted. Significant interaction of the nonuniformity of the supply voltage distribution, the billet's movement, the billet phase heterogeneity and side effect on the ends of the inductor have been shown.
Practical implications
The results received can be used for designing the induction heating unit for moving cylindrical billets made from ferromagnetic material and improving their characteristics.
Originality/value
Investigation of moving cylindrical ferromagnetic billets induction heating can be done by numerical solving the coupled problem including the electromagnetic and thermal boundary problem with additional algebraic equations for the supply voltage distribution.
