The purpose of this paper is to examine whether anonymous reporting channels are effective in detecting fraud against companies. Fraud, which comprises predominantly asset misappropriation, represents a key operational risk and a major cost to organisations. The fraud triangle provides a framework for developing our understanding of how ARCs can increase detection of fraud. Using publicly listed company survey data collected by KPMG in Australia—where ARCs are not mandated—we find a positive association between ARCs and reported fraud. These results indicate (...) that ARCs are effective in detecting fraud. Additional analysis reveals that small firms derive the greatest benefit from adopting ARCs. We also find that independent boards do not directly influence the detection of fraud, but companies with independent boards detect more fraud because they implement ARCs. (shrink)

Experiments on choice blindness support von Hippel & Trivers's (VH&T's) conception of the mind as fundamentally divided, but they also highlight a problem for VH&T's idea of non-conscious self-deception: If I try to trick you into believing that I have a certain preference, and the best way is to also trick myself, I might actually end up having that preference, at all levels of processing.

We focus on two problems with the evolutionary scenario proposed: (1) It bypasses the question of the origins of the communicative and semiotic features that make language distinct from, say, pleasant but meaningless sounds. (2) It does little to explain the absence of language in, for example, chimpanzees: Most of the selection pressures invoked apply just as strongly to chimps. We suggest how these problems could possibly be amended.

In a world of limited resources, it could be argued that companies that aspire to be good corporate citizens need to focus on making best use of resources. User value and environmental harm are created in supply chains and it could therefore be argued that company business ethics should be extended from the company to the entire value chain from the first supplier to the last customer. Starting with a delineation of the linkages between business ethics, corporate sustainability, and the (...) stakeholder concept, this article argues that supply chains generally have a great innovation potential for sustainable development. This potential could be highlighted with system thinking and the use of change management knowledge, promoting not only innovations within technology but also within organizational improvement. We propose process models and performance indicators as means of highlighting improvement potential and thus breaking down normative business ethics' requirements to an opertionalizable corporate level: Good business ethics should focus on maximizing stakeholder value in relation to harm done. Our results indicate that focusing on supply chains reveals previously unknown innovation potential that seems to be related to limited system understanding. The assumption is that increased visibility of opportunities will act as a driver for change. Results also highlight the importance of focusing on sustainability effects of the core business and clearly relating value created to harm done. (shrink)

Reinforcement learning systems usually assume that a value function is defined over all states that can immediately give the value of a particular state or action. These values are used by a selection mechanism to decide which action to take. In contrast, when humans and animals make decisions, they collect evidence for different alternatives over time and take action only when sufficient evidence has been accumulated. We have previously developed a model of memory processing that includes semantic, episodic and working (...) memory in a comprehensive architecture. Here, we describe how this memory mechanism can support decision making when the alternatives cannot be evaluated based on immediate sensory information alone. Instead we first imagine, and then evaluate a possible future that will result from choosing one of the alternatives. Here we present an extended model that can be used as a model for decision making that depends on accumulating evidence over time, whether that information comes from the sequential attention to different sensory properties or from internal simulation of the consequences of making a particular choice. We show how the new model explains both simple immediate choices, choices that depend on multiple sensory factors and complicated selections between alternatives that require forward looking simulations based on episodic and semantic memory structures. In this framework, vicarious trial and error is explained as an internal simulation that accumulates evidence for a particular choice. We argue that a system like this forms the “missing link” between more traditional ideas of semantic and episodic memory, and the associative nature of reinforcement learning. (shrink)

A fundamental assumption of theories of decision-making is that we detect mismatches between intention and outcome, adjust our behavior in the face of error, and adapt to changing circumstances. Is this always the case? We investigated the relation between intention, choice, and introspection. Participants made choices between presented face pairs on the basis of attractiveness, while we covertly manipulated the relationship between choice and outcome that they experienced. Participants failed to notice conspicuous mismatches between their intended choice and the outcome (...) they were presented with, while nevertheless offering introspectively derived reasons for why they chose the way they did. We call this effect choice blindness. (shrink)

Johansson, in “Parfit on Fission,” rejects Parfit’s thesis that fission demonstrates that identity does not matter in survival based on the following assumption (call the person who fissions, “Mr. Fissiony” and the fission products, “Lefty” and “Righty”): It is determinately true that Mr. Fissiony is identical to Lefty or that he is identical to Righty, but it is indeterminate whether Mr. Fissiony is identical to Lefty and it is indeterminate whether Mr. Fissiony is identical to Righty. Johansson argues (...) that there are identity-based answers to the following questions that apply in fission case: (Future Time) Concerning any future time, what matters in my relation to it? (Future Person) Concerning any future individual, what matters in my relation to him? The identity-based answers are these: (Future Time Answer) That I am identical with someone at that time. (Future Person Answer) That it is not false that I and that future individual are identical and that this relation of it not being false that we are identical is not close to not obtaining. I argue that the combination of these answers is inconsistent with the implication that if person C1 at t1 stands in the mattering relation to person C2 at t2, then C1 gets what matters with respect to t2 and that the degree to which the relation specified in Future Person Answer holds between Mr. Fissiony and Lefty in the fission case does not match up to the degree to which Mr. Fissiony gets what matters with respect to Lefty.

The legacy of Nisbett and Wilson’s classic article, Telling More Than We Can Know: Verbal Reports on Mental Processes , is mixed. It is perhaps the most cited article in the recent history of consciousness studies, yet no empirical research program currently exists that continues the work presented in the article. To remedy this, we have introduced an experimental paradigm we call choice blindness [Johansson, P., Hall, L., Sikström, S., & Olsson, A. . Failure to detect mismatches between intention (...) and outcome in a simple decision task. Science, 310, 116–119.]. In the choice blindness paradigm participants fail to notice mismatches between their intended choice and the outcome they are presented with, while nevertheless offering introspectively derived reasons for why they chose the way they did. In this article, we use word-frequency and latent semantic analysis to investigate a corpus of introspective reports collected within the choice blindness paradigm. We contrast the introspective reasons given in non-manipulated vs. manipulated trials, but find very few differences between these two groups of reports. (shrink)

According to the standard version of the counterfactual comparative account of harm, an event is overall harmful for an individual if and only if she would have been on balance better off if it had not occurred. This view faces the “preemption problem.” In the recent literature, there are various ingenious attempts to deal with this problem, some of which involve slight additions to, or modifications of, the counterfactual comparative account. We argue, however, that none of these attempts work, and (...) that the preemption problem continues to haunt the counterfactual comparative account. (shrink)

In a recent article, I criticized Anthony L. Brueckner and John Martin Fischer’s influential argument—appealing to the rationality of our asymmetric attitudes towards past and future pleasures—against the Lucretian claim that death and prenatal non-existence are relevantly similar. Brueckner and Fischer have replied, however, that my critique involves an unjustified shift in temporal perspectives. In this paper, I respond to this charge and also argue that even if it were correct, it would fail to defend Brueckner and Fischer’s proposal against (...) my critique. (shrink)

In this article I discuss the question of whether a person’s existence can be better (or worse) for him than his non-existence. Recently, Nils Holtug and Melinda A. Roberts have defended an affirmative answer. These defenses, I shall argue, do not succeed. In different ways, Holtug and Roberts have got the metaphysics and axiology wrong. However, I also argue that a person’s existence can after all be better (or worse) for him than his non-existence, though for reasons other than those (...) provided by Holtug and Roberts. (shrink)

According to the “deprivation approach,” a person’s death is bad for her to the extent that it deprives her of goods. This approach faces the Lucretian problem that prenatal non-existence deprives us of goods just as much as death does, but does not seem bad at all. The two most prominent responses to this challenge—one of which is provided by Frederik Kaufman (inspired by Thomas Nagel) and the other by Anthony Brueckner and John Martin Fischer—claim that prenatal non-existence is relevantly (...) different from death. This paper criticizes these responses. (shrink)

In this paper, we critically examine Molly Gardner’s favored solution to what she calls “the problem of justified harm.” We argue that Gardner’s view is false and that her arguments in support of it are unconvincing. Finally, we briefly suggest an alternative solution to the problem which avoids the difficulties that beset Gardner’s proposal.

According to immanent realism, there are universals in the spatiotemporal world quite independently of language and the mind. The existence of these universals, furthermore, is not dependent upon there being Platonic universals existing outside the spatiotemporal world. In this paper I will try to show that immanent realism holds not only for many determinate universals, but for some determinable universals as well. In other words, there are ontological determinables as well as conceptual determinables.

The paper argues that causal systems and spatial patterns are species of the same genus, namely pattern, and that a clear view of spatial patterns throws light on some aspects of the ontological nature of causal systems. In particular, it is argued that all patterns (and systems) depend on a fiat delimitation of something which in itself is a unity without borders. Pattern realism is true.

Derek Parfit famously defends a number of surprising views about "fission." One is that, in such a scenario, it is indeterminate whether I have survived or not. Another is that the fission case shows that it does not matter, in itself, whether I survive or not. Most critics of the first view contend that fission makes me cease to exist. Most opponents of the second view contend that fission does not preserve everything that matters in ordinary survival. In this paper (...) I shall provide a critique that does not rely on either of these contentions. There are other, interrelated reasons to reject Parfit's defense of the two theses. In particular, the availability of the following view creates trouble for Parfit: I determinately survive fission, but it is indeterminate which fission product I am. (shrink)

Those who endorse the view that death is in some cases bad for the deceased—a view that, as I shall explain, has considerable bearing on many bioethical issues—need to address the following, Epicurean question: When is death bad for the one who dies? The two most popular answers are "before death" (priorism) and "after death" (subsequentism). Part of the support for these two views consists in the idea that a third answer, "at no time" (atemporalism), makes death unsatisfyingly different from (...) other evils. I argue that this objection is mistaken, and that priorism and subsequentism face problems that atemporalism avoids. Moreover, I argue that if it is nonetheless insisted that we must find a time at which my death is bad for me, we can appeal to periods that begin before my death and end after my death. I end with some implications for posthumous harm. (shrink)

In his recent book, Death and the Afterlife, Samuel Scheffler argues that it matters greatly to us that there be other human beings long after our own deaths. In support of this “Afterlife Thesis,” as I call it, he provides a thought experiment—the “doomsday scenario”—in which we learn that, although we ourselves will live a normal life span, 30 days after our death the earth will be completely destroyed. In this paper I question this “doomsday scenario” support for Scheffler’s Afterlife (...) Thesis. In particular, I suggest that Scheffler has underestimated the importance of a good ending. (shrink)

The paper ends with an argument that says: necessarily, if there are finitely spatially extended particulars, then there are monadic universals. Before that, in order to characterize the distinction between particulars and universals, Roman Ingarden’s notions of existential moments and modes (ways) of being are presented, and a new pair of such existential moments is introduced: multiplicity–monadicity. Also, it is argued that there are not only real universals, but instances of universals (tropes) and fictional universals too.

String theory has been the dominating research field in theoretical physics during the last decades. Despite the considerable time elapse, no new testable predictions have been derived by string theorists and it is understandable that doubts have been voiced. Some people have argued that it is time to give up since testability is wanting. But the majority has not been convinced and they continue to believe that string theory is the right way to go. This situation is interesting for philosophy (...) of science since it highlights several of our central issues. In this paper we will discuss string theory from a number of different perspectives in general methodology. We will also relate the realism/antirealism debate to the current status of string theory. Our goal is two-fold; both to take a look at string theory from philosophical perspectives and to use string theory as a test case for some philosophical issues. (shrink)

It is argued that medical science requires a classificatory system that (a) puts functions in the taxonomic center and (b) does justice ontologically to the difference between the processes which are the realizations of functions and the objects which are their bearers. We propose formulae for constructing such a system and describe some of its benefits. The arguments are general enough to be of interest to all the life sciences.

There is a growing literature on how scientific experts understand risk of technology related to their disciplinary field. Previous research shows that experts have different understandings and perspectives depending on disciplinary culture, organizational affiliation, and how they more broadly look upon their role in society. From a practice-based perspective on risk management as a bottom-up activity embedded in work place routines and everyday interactions, we look, through an ethnographic lens, at the laboratory life of nanoscientists. In the USA and Sweden, (...) two categories of nanoscientists have been studied: upstream scientists who are mainly electrical and physical engineers and downstream scientists who are toxicologists, often with a more multidisciplinary background, including physics, chemistry, biology, and engineering. The results show that although the two groups of scientists share the same norms of appropriate laboratory conduct to promote safety and good science practice, they have very different perspectives on risk with nanomaterials. Upstream scientists downplay risk; they emphasize the innovative potential of the new materials to which they express an affectionate and personalized stance. The downstream scientists, instead, focus on the uncertainties and unpredictability of nanomaterials and they see some materials as potentially highly dangerous. The results highlight the ambiguous and complex role of scientific experts in policy processes about the risk and regulation of nanotechnology. (shrink)

The introduction of new medical treatments based on invasive technologies has often been surrounded by both hopes and fears. Hope, since a new intervention can create new opportunities either in terms of providing a cure for the disease or impairment at hand; or as alleviation of symptoms. Fear, since an invasive treatment involving implanting a medical device can result in unknown complications such as hardware failure and undesirable medical consequences. However, hopes and fears may also arise due to the cultural (...) embeddedness of technology, where a therapy due to ethical, social, political and religious concerns could be perceived as either a blessing or a threat. While Deep Brain Stimulation (DBS) for treatment resistant depression (TRD) is still in its cradle, it is important to be proactive and try to scrutinize both surfacing hopes and fears. Patients will not benefit if a promising treatment is banned or avoided due to unfounded fears, nor will they benefit if DBS is used without scrutinizing the arguments which call for caution. Hence blind optimism is equally troublesome. We suggest that specificity, both in terms of a detailed account of relevant scientific concerns as well as ethical considerations, could be a way to analyse expressed concerns regarding DBS for TRD. This approach is particularly fruitful when applied to hopes and fears evoked by DBS for TRD, since it can reveal if our comprehension of DBS for TRD suffer from various biases which may remain unnoticed at first glance. We suggest that such biases exist, albeit a further analysis is needed to explore this issue in full. (shrink)

:Brain–computer interfaces can enable communication for persons in severe paralysis including locked-in syndrome ; that is, being unable to move or speak while aware. In cases of complete loss of muscle control, termed “complete locked-in syndrome,” a BCI may be the only viable solution to restore communication. However, a widespread ignorance regarding quality of life in LIS, current BCIs, and their potential as an assistive technology for persons in LIS, needlessly causes a harmful situation for this cohort. In addition to (...) their medical condition, these persons also face social barriers often perceived as more impairing than their physical condition. Through social exclusion, stigmatization, and frequently being underestimated in their abilities, these persons are being locked out in addition to being locked-in. In this article, we show how persons in LIS are being locked out, including how key issues addressed in the existing literature on ethics, LIS, and BCIs for communication, such as autonomy, quality of life, and advance directives, may reinforce these confinements; show how these practices violate the United Nations Convention on the Rights of Persons with Disabilities, and suggest that we have a moral responsibility to prevent and stop this exclusion; and discuss the role of BCIs for communication as one means to this end and suggest that a novel approach to BCI research is necessary to acknowledge the moral responsibility toward the end users and avoid violating the human rights of persons in LIS.

Education is often understood as a process whereby children come to conform to the norms teachers believe should govern our practices. This picture problematically presumes that educators know in advance what it means for children to go on the way that is expected of them. In this essay Viktor Johansson suggests a revision of education, through the philosophy of Stanley Cavell, that can account for both the attunement in our practices and the possible dissonance that follows when the teacher (...) and child do not go on together. There is an anxiety generated by the threat of disharmony in our educational undertakings that may drive teachers toward philosophy in educational contexts. Here Johansson offers a philosophical treatment of this intellectual anxiety that teachers may experience when they, upon meeting dissonant children, search for epistemic justifications of their practices—a treatment whereby dissonant children can support teachers in dissolving their intellectual frustrations.

Summary The article argues thatceteris paribus clauses have to be separated from another type of clauses called closure clauses. The former are associated with laws and theories, the latter with test situations of a particular kind. It is also argued that closure clauses, but notceteris paribus clauses, make Popper's falsifiability principle untenable. In that way, it also resolves the quarrel between Popper and Lakatos aboutceteris paribus clauses and falsifiability by saying that both are partly wrong and partly right.

We defend the fundamental ontological-pragmatic principle that where there are continua in reality science is often forced to make partly fiat terminological delimitations. In particular, this principle applies when it comes to describing biological organisms, their parts, properties, and relations. Human-made fiat delimitations are indispensable at the level of both individuals and the natural kinds which they instantiate. The kinds of pragmatically based ‘fiatness’ that we describe can create incompatibilities and lack of interoperability even between properly designed ontologies, if not (...) appropriately handled.

I am honored to respond to Paul Guyer’s elaboration on the role of examples of perfectionism in Cavell’s and Kant’s philosophies. Guyer’s appeal to Kant’s notion of freedom opens the way for suggestive readings of Cavell’s work on moral perfectionism but also, as I will show, for controversy.There are salient aspects of both Kant’s and Cavell’s philosophy that are crucial to understanding perfectionism and, let me call it, perfectionist education, that I wish to emphasize in response to Guyer. In responding (...) to Guyer’s text, I shall do three things. First, I shall explain why I think it is misleading to speak of Cavell’s view that moral perfectionism is involved in a struggle to make oneself intelligible to oneself .. (shrink)

Peter Singer is probably the best-known and most controversial ethicist in the world today. He rigorously applies utilitarian moral theory to issues such as world poverty, the environment, abortion, euthanasia and, most famously, animal welfare. He has also written a book about his grandfather, David Oppenheim, who died in Theresienstadt concentration camp. He is Ira W. DeCamp Professor of Bioethics at Princeton University.

In this article I explore ways to argue about punishment of personal representations in virtual reality. I will defend the idea that such punishing might sometimes be morally required. I offer four different lines of argument: one consequentialistic, one appealing to an idea of appropriateness, one using the notion of organic wholes, and one starting from a supposed inability to determine the limits of the extension of the moral agent. I conclude that all four approaches could, in some cases, justify (...) punishing a virtual reality representation; an avatar. As a consequence of my conclusion, I suggest that our institutionalized criminal justice system must be broadened in scope and punitive measures, in order to cover the new and difficult cases arising in virtual reality.

A pure time preference is a preference for something to occur at one point in time rather than another, merely because of when it occurs in time. Such preferences are widely regarded as paradigm examples of irrational preferences. However, Rosemary Lowry and Martin Peterson have recently argued that, for instance, a pure time preference to go to the opera tonight rather than next month may be rationally permissible, even if the amounts of intrinsic value realized in both cases are identical. (...) In this reply, we argue that Lowry and Peterson's argument is unsuccessful. (shrink)

In an oft-quoted passage from The Principles of Morals and Legislation, Jeremy Bentham addresses the issue of our treatment of animals with the following words: ‘the question is not, Can they reason? nor, can they talk? but, Can they suffer?’ The point is well taken, for surely if animals suffer, they are legitimate objects of our moral concern. It is curious therefore, given the current interest in the moral status of animals, that Bentham's question has been assumed to be merely (...) rhetorical. No-one has seriously examined the claim, central to arguments for animal liberation and animal rights, that animals actually feel pain. Peter Singer's Animal Liberation is perhaps typical in this regard. His treatment of the issue covers a scant seven pages, after which he summarily announces that ‘there are no good reasons, scientific or philosophical, for denying that animals feel pain’. In this paper I shall suggest that the issue of animal pain is not so easily dispensed with, and that the evidence brought forward to demonstrate that animals feel pain is far from conclusive.

Enormous gaps between HIV burden and health care availability in low-income countries raise severe ethical problems. This article analyzes four HIV-priority dilemmas with interest across contexts and health systems. We explore principled distributive conflicts and use the Atkinson index to make explicit trade-offs between health maximization and equality in health. We find that societies need a relatively low aversion to inequality to favor treatment for children, even with large weights assigned to extending the lives of adults: higher inequality aversion is (...) needed to share resources equally between high-cost and low-cost treatment; higher inequality aversion is needed to favor treatment rather than prevention, and the highest inequality aversion is needed to favor sharing treatment between urban and rural regions rather than urban provision of treatment. This type of ethical sensitivity analysis may clarify the ethics of health policy choice. (shrink)
