Advances in neuroscience implicate reentrant signaling as the predominant form of communication between brain areas. This principle was used in a series of masking experiments that defy explanation by feed-forward theories. The masking occurs when a brief display of target plus mask is continued with the mask alone. Two masking processes were found: an early process affected by physical factors such as adapting luminance and a later process affected by attentional factors such as set size. This later process is called (...) masking by object substitution, because it occurs whenever there is a mismatch between the reentrant visual representation and the ongoing lower level activity. Iterative reentrant processing was formalized in a computational model that provides an excellent fit to the data. The model provides a more comprehensive account of all forms of visual masking than do the long-held feed-forward views based on inhibitory contour interactions. (shrink)

Relative blindsight is said to occur when different levels of subjective awareness are obtained at equality of objective performance. Using metacontrast masking, Lau and Passingham reported relative blindsight in normal observers at the shorter of two stimulus-onset asynchronies between target and mask. Experiment 1 replicated the critical asymmetry in subjective awareness at equality of objective performance. We argue that this asymmetry cannot be regarded as evidence for relative blindsight because the observers’ responses were based on different attributes of the stimuli (...) at the two SOAs. With an invariant criterion content , there was no asymmetry in subjective awareness across the two SOAs even though objective performance was the same. Experiment 3 examined the effect of criterion level on estimates of relative blindsight. Collectively, the present results question whether metacontrast masking is a suitable paradigm for establishing relative blindsight. Implications for theories of consciousness are discussed.

The huge amounts spent on store security and crime prevention worldwide, not only costs international businesses, but also amounts to a hidden tax on those law-binding consumers who bear higher prices. Most previous research has focused on shoplifting and ignored many other ways in which consumers cheat businesses. Using a hybrid of both qualitative research and survey approaches in four countries, an index of 37 activities was developed to examine consumers’ unethical activities across UK, US, France, and Austria. The findings (...) indicate that around three quarters of consumers in all four countries can be classified as heavy offenders for these minor cheats. The paper argues that government agencies, marketers, and retailers should adopt more pro-active preventative approaches, rather than reactive loss limitation measures to combat unethical behavior.

We study the preservation of certain properties under products of classes of finite structures. In particular, we examine indivisibility, definable self-similarity, the amalgamation property, and the disjoint n-amalgamation property. We explore how each of these properties interacts with the lexicographic product, full product, and free superposition of classes of structures. Additionally, we consider the classes of theories which admit configurations indexed by these products. In particular, we show that, under mild assumptions, the products considered in this article do not yield (...) new classes of theories. (shrink)

Legal scholars attribute a great deal of importance to the linguistic dimension behind recodification. According to them, language contributes greatly to the improvement of both the accessibility and clarity of the law. Nevertheless, little research on the linguistic aspects of codification exists within both linguistics and legal theory. Consequently, it seems worthwhile to study this linguistic dimension more in depth. To this aim, the recent legislative proposals to recodify various economic, civil and criminal codes in Belgium serve as a useful (...) case study to improve our understanding of the linguistic challenges of recodification. In this article we will look at the linguistic comments made by the Belgian Council of State, a state organ which offers technical advice to the legislator, on the relevant proposals and consider the type of linguistic comments made, and, their implementation by the legislator. On the one hand, such an analysis allows us to single out the linguistic problems accompanying the Belgian recodification and, on the other, to elaborate on them with the help of the insights provided by legal theory. In doing so, we hope for our analysis to be a useful point of reference both for research on the Belgian recodification and other legal/linguistic approaches to recodification in general. (shrink)

This study examines the relationship between the ethical behavior and customer orientation of insurance sales agents engaged in the selling of complex services, e.g. health, life, auto, and property insurance. The effect of ethical and customer-oriented behavior, measured by the SOCO scale (Saxe and Weitz, 1982), on the annual premiums generated by the agents is also investigated. Customeroriented sales agents are found to engage in less unethical behavior than their sales-oriented counterparts. Further, sales-oriented agents are found to perceive greater levels (...) of unethical behavior among their significant others. Alarmingly, higher levels of sales premiums are found among those agents who engage in unethical behavior. (shrink)

The Guarded Negation Fragment (GNFO) is a fragment of first-order logic that contains all positive existential formulas, can express the first-order translations of basic modal logic and of many description logics, along with many sentences that arise in databases. It has been shown that the syntax of GNFO is restrictive enough so that computational problems such as validity and satisfiability are still decidable. This suggests that, in spite of its expressive power, GNFO formulas are amenable to novel optimizations. In this (...) article we study the model theory of GNFO formulas. Our results include effective preservation theorems for GNFO, effective Craig Interpolation and Beth Definability results, and the ability to express the certain answers of queries with respect to a large class of GNFO sentences within very restricted logics.

Respect for an individual’s autonomy determines that doctors should inform patients if their illness is terminal. This becomes complicated when the terminal diagnosis is recent and death is imminent. The authors examine the admission to paediatric intensive care of an adolescent with terminal respiratory failure. While fully ventilated, the patient was kept sedated and comfortable but when breathing spontaneously he was capable of non-verbal communication and understanding. Once resedated and reintubated, intense debate ensued over whether to wake the patient to (...) tell him he was going to die. The authors discuss the ethical arguments that surrounded their decision.

In the final decades of the 20th century, issues such as identity, Otherness and the role of social and cultural boundaries have been prominent in social theory, sociology and cultural studies. In this context, an analysis of Bauman's work is important because it raises pertinent questions pertaining to the nature of social and cultural boundaries and the nature of boundary construction under modernity. The metaphors of inside and outside and the idea of the boundary are significant in Bauman's critique of (...) modernity's search for a meta-order and in his examination of strangerhood. The article illustrates how this ordering process manifests itself at the individual and societal levels of modernity. Bauman's contention is that modernity's search for a meta-order leads to the construction of boundaries and to exclusionary practices. It is the presence of the Third, for Bauman, which threatens the certainty of order. Different images of the stranger in Bauman's work are identified and the ways in which Bauman's conception of freedom and `community' is intrinsically linked to his work on the ambivalent stranger are demonstrated.

In an effort to ensure access to justice, Australian courts have fashioned a unique hybrid opt in-opt out process known as “closed classes.” The rationale that underlies closed classes is to prevent free-riding that may undercut the position of funders and class action law firms reliant upon entering into agreements with a critical mass of class members. However, multiple closed classes also pose problems for respondents seeking the comfort of finality. To secure settlement and thus ultimately benefit participating class members, (...) Australian courts have formulated a procedure whereby the closed class is opened and nonparticipating class members are invited to either register their claims or opt out so that thereafter those who do not register and those who opt out are effectively precluded by res judicata from making further related claims. We argue that Australian courts’ support of closed classes, while driven by pragmatism, has produced unintended consequences. Many relate to the ethical dilemmas faced by class action law firms and litigation funders seeking to advance the interests of participating class members over and above those of nonparticipating class members. The Full Federal Court has recently approved an alternative common fund approach. However, questions remain as to whether Australian courts are appropriately equipped to measure and compare the alternative transaction costs associated with the current and proposed approach, and whether they are appropriately equipped to determine the commercial rectitude and fairness of litigation funding agreements.

This paper takes as its starting point a decision to accept a particular commission for a piece of educational research which is subject to contractual restrictions. In the light of recent debate on the contentious politics and ethics of contractual research, it then addresses the problem of what might constitute an ethical defence, or critique, of such research and such contracts.
