The Responsibilities of Engineers

Knowledge of the responsibilities of engineers is the foundation for answering ethical questions about the work of engineers. This paper defines the responsibilities of engineers by considering what constitutes the nature of engineering as a particular form of activity. Specifically, this paper focuses on the ethical responsibilities of engineers qua engineers. Such responsibilities refer to the duties acquired in virtue of being a member of a group. We examine the practice of engineering, drawing on the idea of practices developed by philosopher Alasdair MacIntyre, and show how the idea of a practice is important for identifying and justifying the responsibilities of engineers. To demonstrate the contribution that knowledge of the responsibilities of engineers makes to engineering ethics, a case study from structural engineering is discussed. The discussion of the failure of the Sleipner A Platform off the coast of Norway in 1991 demonstrates how the responsibilities of engineers can be derived from knowledge of the nature of engineering and its context.     

Model of Occupational Empowerment and Gunnarsson’s Tree Theme: Intervention for Mothers in Recovery

In this study the authors investigated Gunnarsson's Tree Theme Method as an occupational therapy intervention program for mothers in recovery from addiction in accordance with Fisher and Hotchkiss's Model of Occupational Empowerment (2008 Fisher , G. , &; Hotchkiss , A. ( 2008 ). A model of occupational empowerment for marginalized populations in community environments . Occupational Therapy in Health Care , 22 , 55 – 71 . Retrieved from EBSCOhost .[Crossref] , [Google Scholar]). Each session of this mixed design study consisted of relaxation exercises, discussions on self-help readings, and participation in the Tree Theme Method. Two participants out of three improved their personal growth initiative. Participant reflection provided insight into the women's inner feelings. Fisher and Hotchkiss's model (2008 Fisher , G. , &; Hotchkiss , A. ( 2008 ). A model of occupational empowerment for marginalized populations in community environments . Occupational Therapy in Health Care , 22 , 55 – 71 . Retrieved from EBSCOhost .[Crossref] , [Google Scholar]) was supported as the women achieved personal growth. Further research is needed concerning how this may guide occupational therapy practice with disadvantaged populations.     

The Verifiability Approach: Countermeasures Facilitate its Ability to Discriminate Between Truths and Lies

According to the verifiability approach, liars tend to provide details that cannot be checked by the investigator and awareness of this increases the investigator's ability to detect lies. In the present experiment, we replicated previous findings in a more realistic paradigm and examined the vulnerability of the verifiability approach to countermeasures. For this purpose, we collected written statements from 44 mock criminals (liars) and 43 innocents (truth tellers), whereas half of them were told before writing the statements that the verifiability of their statements will be checked. Results showed that ‘informing’ encouraged truth tellers but not liars to provide more verifiable details and increased the ability to detect lies. These findings suggest that verifiability approach is less vulnerable to countermeasures than other lie detection tools. On the contrary, in the current experiment, notifying interviewees about the mechanism of the approach benefited lie detection. Copyright © 2013 John Wiley & Sons, Ltd.     

Misleading Suggestions can Alter Later Memory Reports even Following a Cognitive Interview

Taking an immediate recall test prior to misinformation exposure can increase eyewitness suggestibility—a finding termed retrieval‐enhanced suggestibility. Here, we examined whether retrieval‐enhanced suggestibility would occur when participants were administered an immediate Cognitive Interview (CI). The CI is an investigative interviewing technique that consistently elicits more correct details in memory reports than standard interviews. In this study, participants watched a video of a crime and then completed a distractor task (control condition), a free recall test, or the CI. They then heard misinformation presented in a narrative. Participants produced more accurate memory details in the CI than in free recall despite spending equal time on both tasks. However, the CI also increased the later report of misinformation relative to the control condition. These results show that initial retrieval can increase subsequent suggestibility even when such retrieval occurs under relatively ideal conditions. Copyright © 2013 John Wiley & Sons, Ltd.     

Evaluating the Source of the Risks Associated with Natural Events

Within philosophy there has been little discussion of the risks associated with natural events such as earthquakes. The first objective of this paper is to demonstrate why such risks should be the subject of more sustained philosophical interest. We argue that we cannot simply apply to risks associated with natural events those insights and frameworks for moral evaluation developed in the literature considering ordinary risks, technological risks and the risks posed by anthropogenic climate change. The second objective of this paper is to identify and develop a framework for the moral evaluation of the source of the risks associated with natural events, or the actions which sustain and impact such risks. Our discussion concentrates on the ways the construction and modification of built and natural environments can alter the probability of occurrence of natural events and the character and magnitude of the impact that such events have. We then argue for the need to develop a standard of reasonable care for decisions about the built and modified natural environment, which accounts for technical and resource constraints, as well as the place of natural hazard mitigation in public policy.
