Abstract
Purpose
The purpose of this paper is to develop the understanding of how external loads are reacted through preloaded bolted joints and the interaction of the joint elements. The paper develops ideas from how to do an analysis to understanding the implications of the results.
Design/methodology/approach
Classical methods of analysis are applied to preloaded bolted joints, made with multiple bolts. The paper considers both the detailed analysis of bolts stresses, fatigue analysis and load-based design analysis, to demonstrate the structural integrity of preloaded bolted joints.
Findings
In preloaded joints the external tensile axial load and moments are mainly supported by changes in contact pressure at the faying surface. Only a small proportion of the external loads produce changes in bolt tensile stress. The bolts have a significant mean stress but experience a low working stress range. This low stress range is a factor in explaning why preloaded bolted joints have good fatigue performance.
Practical implications
In many cases the methods presented are adequate to demonstrate the structural integrity of joints. In some cases finite element methods may be more appropriate, and the methods discussed can be used in the validation process.
Originality/value
The paper brings together a number of concepts and links them into a practical design analysis process for preloaded bolted joints. Interpretation of results, within the context of design standards, is provided.

Abstract
Purpose
This chapter delves into the controversy over detention and interrogation in the war on terror carried out by American operatives. While attending to political, legal, and ethical concerns, critical attention is directed at the manner by which certain interrogation techniques have been framed as being “scientific” and therefore effective in extracting truthful disclosures from terror suspects.
Methodology/approach
Drawing on extensive legal and medical literature, the critique offers a postmodern analysis by raising serious questions over the effectiveness and legitimacy of enhanced interrogation espoused by the Bush administration. By doing so, the conceits of the war on terror are exposed and confronted.
Findings
In 2014, the report of the Senate Select Committee on Intelligence (Study of the CIA’s Detention and Interrogation Program) was unclassified and released to the public. Among other revelations, the document clearly shows that interrogators and their psychological consultants committed torture. In doing so, they often relied on medical knowledge for harming, rather than healing. Ethical and legal remedies aimed at correcting those problems are recommended.
Originality/value
The chapter delivers a sophisticated critique that blends recently revealed evidence of torture with postmodern interpretation. While casting doubt on the effectiveness and legitimacy of enhanced interrogation, discussion throws critical light on incidents of human rights abuses committed by health professionals. Paradoxically, those physicians and psychologists opted to use their medical skills and expertise to inflict suffering rather than alleviating it. Those acts constitute egregious ethical and legal violations that warrant prosecution.

Abstract
Executives at biotechnology firm Genzyme are debating funding a clinical trial for a new version of a medical device called Synvisc. The trial is expensive and the odds of success are not high, but the upside is substantial. The case presents a common business question: invest or not? The case forces students to think about customer insights, wrestle with a number of complex issues, and evaluate the financials of the decision.
The case is ideal for teaching financial analysis and decision making. It can also be used to teach marketing, new product strategy, and healthcare industry management.

Abstract
Cultural criminologists have long been interested in the politics of crime and deviance, whether that be in relation to youth subculture resistance or the social reaction to transgression evident in the media construction of folk devils and moral panics. While contemporary ‘new’ cultural criminology continues to be focused on the situated experience of deviant ‘edgeworkers’, this chapter argues cultural criminology’s concern with the crime-media nexus provides particularly fertile ground for exploring insights provided by activists, academics, professional journalists and citizen journalists around informal interventions on formal criminal justice processes using social media and digital technologies. Drawing on examples from a burgeoning body of crime-media research, the chapter makes a case for ‘cultural criminology activism’, which, like activist criminology, is consciously disengaged from mainstream criminology’s alignment with the neoliberal-carceral state and its reformist agenda.

Abstract
Purpose
For insights into the debate between consultants who advocate authentic, character-based leadership and those that believe leadership is primarily an exercise of political power, S & L interviewed Professor Jeffrey Pfeffer, author of Leadership BS: Fixing Workplaces and Careers One Truth at a Time.
Design/methodology/approach
Professor Pfeffer believes “By any measure or set of relevant measures, the leadership industry has failed and continues to do so.” The interviewer asks him why he reached this conclusion and what implications this has for practitioners.
Findings
Simply put, leaders need to be true to what others need from them, not to how they may be feeling.
Practical implications
Professor Pfeffer offers a reminder of the enduring functionality of political skills and acumen in the workplace, which many adherents of the “inspirational leadership” approach don’t seem to want to embrace.
Originality/value
Professor Pfeffer offers a no-holds-barred account of the intersection of modern workplace realities and self-interested leadership.
