The potential negative impacts of biological pest control on non-target species have become the focus of a contentious debate. In this article, we use examples from both classical and augmentative biological control of fruit fly pests in Hawaii to address several important factors in assessing non-target risks of fruit fly parasitoids. Several fruit fly parasitoids have been introduced to Hawaii and contribute substantially to the reduction of pest populations in the state's farms and forests. However, an historical lack of host-specificity (...) testing of these parasitoids with non-target species has raised concerns about their impact on non-pest fruit flies, including some flies deliberately introduced for biological control of weeds and others that are endemic Hawaiian species. When developing protocols to assess risks of introduced fruit fly parasitoids, we need first to define an appropriate range of species against which host specificity should be tested. For assessing susceptibility of a non-target species to parasitoids, behavioral tests are as important as suitability tests. Experimental factors, such as host-exposure substrate, absence or presence of preferred hosts, and laboratory vs. natural conditions, are shown to affect the results of host-specificity tests and risk analysis. Still, assessing long-term, indirect ecological impacts of parasitoids and weighing potential risks and benefits in multiple dimensions remains a challenge to environmentalists, conservationists, applied ecologists, and biocontrol practitioners.

Within any organization (e.g. a hospital or clinic) the perception of the way things operate may vary dramatically as a function of one’s location in the organizational hierarchy as well as one’s professional discipline. Interorganizational variability depends on organizational coherence, safety, and stability. In this four-nation (Canada, Ireland, Australia, and Korea) qualitative study of 42 nurses, we explored their perception of how ethical decisions are made, the nurses’ hospital role, and the extent to which their voices were heard. These nurses (...) suggested that their voices were silenced (often voluntarily) or were not expressed in terms of ethical decision making. Finally, they perceived that their approach to ethical decision making differed from physicians. (shrink)

The prospect of using genome technologies to modify the human germline has raised profound moral disagreement but also emphasizes the need for wide-ranging discussion and a well-informed policy response. The Hinxton Group brought together scientists, ethicists, policymakers, and journal editors for an international, interdisciplinary meeting on this subject. This consensus statement formulated by the group calls for support of genome editing research and the development of a scientific roadmap for safety and efficacy; recognizes the ethical challenges involved in clinical reproductive (...) applications of genome editing but, importantly, rejects the idea that human reproductive germline modification is necessarily morally unacceptable; and highlights the importance of meaningful engagement in discussions of genome editing and the development of regulation and oversight mechanisms to govern future uses of such technologies.

A recent article in this journal described practical and conceptual difficulties faced by public health researchers studying scabies outbreaks in British residential care facilities. Their study population was elderly, decisionally incapacitated residents, many of whom lacked a legally appropriate decision-maker for healthcare decisions. The researchers reported difficulties securing Research Ethics Committee approval. As practicing healthcare ethicists working in a large Canadian research hospital, we are familiar with this challenge and welcomed the authors’ invitation to join the discussion of the ‘outstanding (...) ambiguities and further questions’ that their experience uncovered. We propose a Power of Attorney for Research as one substantive solution to help address the problems they identified. Although we acknowledge the familiar shortcomings associated with Advance Directives in the clinical context, we believe that Powers of Attorney for Research Participation, accompanied by Advance Research Directives, may increase the likelihood of gaining deeper understandings of potential participant’s values and priorities and how they might apply to foreseeable research opportunities.

The stated aim of this investigation is to clarify and critically examine the philosophical concepts inherent in the cosmological argument: he aspires to investigate the argument rather than to either refute critics or support defenders. He treats both the thirteenth century versions of Aquinas and Duns Scotus and the eighteenth century versions developed by Samuel Clarke and Leibniz, but attaches greater importance and spends more time with the latter, finding them both more sophisticated and more fruitful for investigation. The eighteenth (...) century forms make no use of "what many philosophers would regard as a strange and perhaps nonexistent kind of causal series" and, according to the author, are more relevant because modern objections, e.g. those of Hume and Russell, aim at the eighteenth century forms.

We add texture to the conclusion of Duchon and Drake (Journal of Business Ethics, 85, 2009, 301) that extreme narcissism is associated with unethical conduct. We argue that the special features possessed by financial accounting facilitate extreme narcissism in susceptible CEOs. In particular, we propose that extremely narcissistic CEOs are key players in a recurring discourse cycle facilitated by financial accounting language and measures. Such CEOs project themselves as the corporation they lead, construct a narrative about the corporation and themselves (...) using financial accounting measures, and then reflect on how their accounting-constructed performance is perceived by stakeholders. We do not present empirical evidence about whether the use of accounting language and measures leads to unethical behaviour by extreme narcissistic CEOs — although the conclusions of Duchon and Drake (2009) suggest empirical support is probable. Rather, we focus on developing alertness to the potential for accounting, when engaged by an extremely narcissistic CEO, to be a precursor or implement of unethical behaviour. (shrink)
