Abstract
The growing dependence of modern society on telecommunication and information networks and e‐type systems has become inevitable. However, those types of systems are vulnerable to malicious attacks. The speed and automation in network attack techniques continue to increase. An achievable automated attack or unauthorised access to a particular organization network could lead to devastating effects on its reputation and imminent loss of life. In this paper an innovative way is proposed to detect network attacks of a distributed nature such as denial of service (DoS) attacks. The proposed scheme is mainly based on neuro‐fuzzy intelligence in order to learn and determine the fuzzy parameter functions that represent network traffic behaviour. Neuro‐fuzzy agents combine the features of fuzzy logic and neural networks and they have been proposed to overcome the limitations of human expertise in defining fuzzy membership functions, especially for complex environments, such as information networks.

Abstract
In today’s society, information and communications technology (ICT) is the force that drives prosperity and provides a higher standard of living. All other e‐services and infrastructures tend to play a major role in our daily life and global economy. The growing dependence on such systems, however, has increased their vulnerability to cyber attacks. Any failure to these systems typically would lead to a huge impact, not only on businesses, but also human life, that depends on such interconnected systems. The growing potential for telecommunications network infrastructures problems stems from their nature of openness. A successful attempt for a network attack to a particular organization’s network could have devastating effects on the security of the organisation. In this paper we propose an innovative way to counteract distributed protocols attacks such as distributed denial of service (DDoS) attacks using intelligent fuzzy agents.

Abstract
In the wake of numerous late twentieth century cult disasters, and most recently, the September 11 tragedy, this paper considers the question, why do people obey outrageous commands from charismatic authorities? According to Gary Becker, “the economic ap‐proach provides a valuable unified framework for understanding all human behavior” (Becker 1976:14). We test this generalization by attempting to explain, in terms of rational choice theory, the behavior of two members of infamous cults, the Manson Family and the Ragneesh Foundation International. Each of these subjects slavishly obeyed orders from a charismatic personality, one to the extent of committing murder. Were they mentally ill or rationally maximizing their utility? We consider these theoretical options. In August of 1969 Charles Manson ordered several of his followers to commit gruesome murders for the purpose of initiating the apocalypse. They obeyed. In late 1978, Jim Jones commanded over 900 members of the Peoples Temple to commit suicide. They obeyed. From 1981 to 1985, executing orders to build utopia perceived to come from their guru, members of the Ragneesh Foundation International terrorized the inhabitants of Antelope, Oregon. Similarly, followers of Osama Bin Laden are suspected of carrying out the disastrous suicide murders of September 11. Over past decades, the incidence of violence involving submission to a charismatic leader appears to be escalating. Increasingly the public must contend with the “awesome power” of charisma, “enshrouded in a mystique of irrationality” (Bradley 1987: 3–4). The extent to which followers committing criminal acts of obedience may be held accountable has become a pressing legal issue. How can this kind of volatile religious commitment be explained? In recent years, experts on cults have experimented with rational choice theory. According to economist, Gary Becker, “the economic approach provides a valuable unified framework for understanding all human behavior” (Becker 1976: 14). We test this extravagant claim with two cases of seemingly irrational commitment to a charismatic cult leader—one a follower of Bhagwan Rajneesh, the other a Manson Family killer. These subjects are not representative cult members but rather were chosen because they demonstrated an exceptional loyalty to their leaders that has been widely construed as the result of brainwashing or insanity. Rather than survey data, we rely on autobiographical testimonies since they offer a more detailed and comprehensive view of the thought processes that motivate behavior, the subject matter of this paper.

Abstract
Prosecutions under Criminal Law, associated in the minds of most people with “criminal offences” of a serious nature—“crime” in the traditional sense—and undertaken by the police authorities, constitute a very large and rather untidy body of public law. It includes a large and constantly growing number of offences in respect of which prosecutions are undertaken by various corporate bodies who, as in the case of local authorities, have a duty albeit with a power of discretion, to prosecute. There would appear to be little in common between such offences, as smoking in the presence of open food or failing to provide soap, nail‐brushes, etc, for food handlers, and the villainy and violence of the criminal, but their misdeeds are all criminal offences and subject to the same law. Other countries, such as France, have definite Criminal Codes and these offences against statutes and statutory instruments which in English Law are dealt with in the broad field of Criminal Law, are subject to special administrative procedure. It has obvious advantages. Although in England and Wales, prosecutions are undertaken by police authorities, local authorities, public corporations, even professional bodies and private individuals, with a few statutory exceptions for which the Attorney‐General's fiat or consent of the Director of Public Prosecutions is necessary, may instigate a prosecution against anyone if he can provide prima facie evidence to support it. In Scotland, prosecutions are instituted at the instigation of the various authorities by an officer, the Procurator‐Fiscal. Many advocate such a system for England and Wales, despite the enormous difference in the volume of litigation. Supervision of prosecutions on a much smaller scale is by the Director of Public Prosecutions, an office created in 1879, with power to institute and carry on criminal proceedings—this is the less significant of his duties, the number of such prosecutions usually being only several thousands per year—the most important being to advise and assist chief officers of police, clerks to the magistrates and any others concerned with criminal proceedings Regulations govern the cases in which DPP may act, mainly cases of public interest. The enormous growth of summary jurisdiction over the years, especially that arising from so‐called secondary legislation, is largely outside his sphere.

Abstract
Purpose
Additive manufacturing (AM) studies on Inconel 718 (IN718) have focused on exploring its tensile and fatigue response. As IN718 is used in the propulsion and energy sector, the impact of shearing is also critical to ensuring the durability of these components. As such, this study aims to explore the relation between build orientation on the shear cyclic response of direct metal laser sintered (DMLS) IN718.
Design/methodology/approach
IN718 torsion specimens were manufactured along six build orientations: (100)-X, (010)-Y, (001)-Z, (110)-XY45, (101)-XZ45 and (011)-YZ45, using the DMLS process. Torsional fatigue testing was performed on as-built specimens, from which fracture behavior, surface roughness, softening/hardening response and monotonic/cyclic shear torsional properties were assessed.
Findings
DMLS IN718 was found to exhibit transversely isotropic behavior. In terms of shear stress range and shear modulus, Z > (X, XY45, Y) > (XZ45, YZ45). Specimens cyclically hardened to stabilization and softened to fracture. In terms of torsional fatigue fracture response, the Z, XZ45 and YZ45 specimens exhibited crack initiation and propagation from internal defects, whereas cracks were found to initiate at the surface and propagate between and through build layers for the X, Y and XY45 specimens.
Originality/value
This study reports the torsional cyclic response and shear moduli exhibited by as-built DMLS IN718 manufactured along varying build orientations. The findings are applicable for researchers because of the wide use of IN718 in the gas turbine industry, and the current trend to replace conventional manufacturing with AM.

Abstract
Purpose
Impact investment is an emergent field worldwide and it can play an especially important role in Africa. The aim of this study was to examine how impact investors in South Africa manage the tensions between financial returns and social impact.
Design/methodology/approach
The research was based on 15 semi-structured interviews with key stakeholders in the impact investment community in South Africa to understand the related challenges, trade-offs and tensions.
Findings
There are two opposing views expressed as to whether the tensions between financial return and social impact result in trade-offs. It is proposed that impact investors embrace this duality and seek to approach it through a contingency and a paradox view. The tensions can be approached by focussing on values alignment, contracting processes, engaged leadership and sector identification. The authors integrate the findings into a proposed framework for effective tension management in an impact investment portfolio.
Research limitations/implications
This study was limited to selected South African interviewees. It would be valuable to extend the study to other African countries.
Practical implications
The issue of values alignment between investors, fund managers and investee firms is an important finding for practice. As is the four-part iterative framework for sensing the operating environment, defining impact, organising internally and defining the investment approach.
Originality/value
This study contributes empirical evidence to scholarship around organisational tensions, especially work in hybrid organisations. It affirms the value of a nuanced application of paradox theory. It examines these tensions through the lived experience of impact investing professionals in an emerging market context.

Abstract
Accounts manipulation has been the subject of research, discussion and even controversy in several countries including the USA, Canada, the U.K., Australia, Finland and France. The objective of this paper is to provide a comprehensive review of the literature and propose a conceptual framework for accounts manipulation. This framework is based on the possibility of wealth transfer between the different stake‐holders, and in practice, the target of the manipulation appears generally to be the earnings per share and the debt/equity ratio. The paper also describes the different actors involved and their potential gains and losses. We review the literature on the various techniques of accounts manipulation: earnings management, income smoothing, big bath accounting, creative accounting, and window‐dressing. The various definitions of all these, the main motivations behind their application and the research methodologies used are all examined. This study reveals that all the above techniques have common elements, but there are also important differences between them.

Abstract
Purpose
The purpose of this paper is to investigate the effect of chief executive officer (CEO) characteristics and involvement in networks on strategic management accounting (SMA) and, in turn, the indirect effect of SMA on company performance.
Design/methodology/approach
A model is advanced and tested using partial least-squares path modelling and data were collected from a sample of 121 service small and medium-sized enterprises (SMEs) in Malaysia.
Findings
The results indicate significant and positive relationships between the CEO education and the application of SMA as well as between involvement in networks and SMA. Moreover, it is found that SMA has an indirect effect in relations of CEO education, involvement in networks and company performance.
Practical implications
SMEs’ leaders may realize their important role in affecting outcomes by their choices, which are in turn affected by their characteristics and activities.
Originality/value
This study provides an empirical evidence on the impact of two new factors on the SMA by considering contingency theory and upper echelons theory simultaneously for explaining relationships and developing a new model.

Abstract
New Age philosophies are having an increasingly important influence on contemporary life. They offer a challengingly holistic view of human potential, and are available in numerous publications and formats. Public library collections often marginalize New Age materials, and find selecting and acquiring them a challenge. Argues that greater awareness of what such materials have to offer would answer growing demands from users and provide spiritual and cultural benefit for the community.
