A major shift has taken place since the 1960s concerning disclosure to patients that they have a diagnosis of cancer and that their disease is considered terminal. Full disclosure is now considered the patient's right in the United States. However, there remain many countries in which nondisclosure is still the norm. When patients from those countries are diagnosed with cancer in America, differences in attitudes and expectations can cause conflict and misunderstanding.

Water is the major contributor to the eating and keeping qualities and structure of baked products. Its management and control during preparation, processing, baking, cooling and storage is essential for the optimisation of product quality. This successful and highly practical volume describes in detail the role and control of water in the formation of cake batters, bread, pastry and biscuit doughs, their subsequent processing and the baked product. Now in a fully revised and updated second edition, the book has been (...) expanded and developed through the inclusion of new information and references related to the formation and processing of batters and dough into baked products. The new edition includes a selection of case studies based on practical experience in the manufacture and optimisation of baked products. Each case study, illustrated as appropriate, considers the various roles that water may play in different manufacturing contexts. The book is aimed at food scientists and technologists in bakery companies; ingredient suppliers; flour millers; researchers and students in academic food science departments. (shrink)

The rhetoric of eschatology was formative of early Christian spirituality. Through such discourse the New Testament writers reshaped the community's perception of time and space, and enabled their audiences to “learn Christ.”.

We construct a quantum logic which generates the usual quark states. It follows from this model that quarks can combine only in quark-antiquark pairs and quark (and antiquark) triples. The ground meson and baryon states are also generated and gluons are discussed.

We present a new approach to measurement theory. Our definition of measurement is motivated by direct laboratory procedures as they are carried out in practice. The theory is developed within the quantum logic framework. This work clarifies an important problem in the quantum logic approach; namely, where the Hilbert space comes from. We consider the relationship between measurements and observables, and present a Hilbert space embedding theorem. We conclude with a discussion of charge systems.

LetB be the set of bounded observables on a quantum logic. A mapJ: B →R is called an expectation functional ifJ is normalized, positive, continuous, and compatibly linear. Two questions are considered. IsJ linear, and isJ an expectation relative to some state? It is shown that the answers are affirmative for hidden variable logics and most Hilbert space logics. An example is given which shows thatJ can be nonlinear on an arbitrary quantum logic.

A discrete quantum mechanics is developed and used to construct models for discrete space-time and for the internal dynamics of elementary particles. This dynamics is given in terms of particles performing a quantum random walk on a multigraph.

It is frequently argued that reality and locality are incompatible with the predictions of quantum mechanics. Various investigators have used this as evidence for the existence of hidden variables. However, Bell's inequalities seem to refute this possibility. Since the above arguments are made within the framework of conventional probability theory, we contend that an alternative solution can be found by an extension of this theory. Elaborating on some ideas of I. Pitowski, we show that within the framework of a generalized (...) probability theory, reality, locality, hidden variables, and the predictions of quantum mechanics can be maintained together. Although our principal model in this work is a spin system, there are indications that this program can be extended to more general systems. (shrink)

We present a survey of a finite-dimensional quark model. We begin with a discussion of measurements on a quantum logic. After making the fundamental assumption that there are three basic colors, the measurement theory provides a natural embedding of the quantum logic into a finite-dimensional Hilbert space. This Hilbert space represents the space of pure quark states. Finite-dimensional quantum mechanics is discussed and the color, and flavor observables are derived. Quark and baryon Hamiltonians are proposed, and a brief description of (...) quark field theory is given. (shrink)

El artículo aborda cómo el género oral de las predicaciones agustinianas puede ayudar a la interpretación académica de la teología de san Agustín, de sus ideas, y también puede ayudar a entender mejor a sus oyentes.

Entanglement measures quantify the amount of quantum entanglement that is contained in quantum states. Typically, different entanglement measures do not have to be partially ordered. The presence of a definite partial order between two entanglement measures for all quantum states, however, allows for meaningful conceptualization of sensitivity to entanglement, which will be greater for the entanglement measure that produces the larger numerical values. Here, we have investigated the partial order between the normalized versions of four entanglement measures based on Schmidt (...) decomposition of bipartite pure quantum states, namely, concurrence, tangle, entanglement robustness and Schmidt number. We have shown that among those four measures, the concurrence and the Schmidt number have the highest and the lowest sensitivity to quantum entanglement, respectively. Further, we have demonstrated how these measures could be used to track the dynamics of quantum entanglement in a simple quantum toy model composed of two qutrits. Lastly, we have employed state-dependent entanglement statistics to compute measurable correlations between the outcomes of quantum observables in agreement with the uncertainty principle. The presented results could be helpful in quantum applications that require monitoring of the available quantum resources for sharp identification of temporal points of maximal entanglement or system separability.

We introduce and study the D-model, which reflects the simplest situation in which one wants to calibrate an observable. We discuss the question of representing the statistics of the D-model in the context of an effect algebra.

In this paper we argue that autobiographical memory can be conceptualized as a mental state resulting from the interplay of a set of psychological capacities?self-reflection, self-agency, self-ownership and personal temporality?that transform a memorial representation into an autobiographical personal experience. We first review evidence from a variety of clinical domains?for example, amnesia, autism, frontal lobe pathology, schizophrenia?showing that breakdowns in any of the proposed components can produce impairments in autobiographical recollection, and conclude that the self-reflection, agency, ownership, and personal temporality are (...) individually necessary and jointly sufficient for autobiographical memorial experience. We then suggest a taxonomy of amnesic disorders derived from consideration of the consequences of breakdown in each of the individual component processes that contribute to the experience of autobiographical recollection.

This paper augments Hailperin's substantial efforts to place Boole's algebra of logic on a solid footing. Namely Horn sentences are used to give a modern formulation of the principle that Boole adopted in 1854 as the foundation for his algebra of logic—we call this principle The Rule of 0 and 1.

Advance care directives for health care have been promoted as a way to improve end-of-life decision making. These documents allow a patient to state, in advance of incapacity, the types of medical treatments they would like to receive, to name a surrogate to make those decisions, or to do both. Although studies have shown that both physicians and patients generally have positive attitudes about the use of these documents, relatively few individuals have actually completed one.What underlies this discrepancy between attitudes (...) and behavior with regard to advance care directives? One obvious explanation is lack of access. Emanuel et al. estimated that approximately 90 percent of the population desire an advance care directive, and they pointed to access as the major barrier. Yet interventions that increase accessibility have typically failed to yield more than a 20 percent completion rate. Thus, it appears that access is not the sole determinant of advance care directive completion. (shrink)

We define qualia space Q to be the space of all possible conscious experience. For simplicity we restrict ourselves to perceptual experience only, though other kinds of experience could also be considered. Qualia space is a highly idealized concept that unifies the perceptual experience of all possible brains. We argue that Q is a closed pointed cone in an infinite-dimensional separable real topological vector space. This quite technical structure can be explained for the most part in a simple, intuitive way. (...) The structure of qualia space allows us to consider and even answer in a precise way such questions as: Is there a continuous path from the sensation of blue to the sensation of pain? Once we fix a desired accuracy of approximation, do there exist finitely many perceptual experiences such that any possible perceptual experience is approximately equal to one of them? What should be meant by ‘fundamentally different’ perceptual experiences? There is the possibility of additional structure, such as a Hilbert space structure on the vector space in which Q is embedded. (shrink)

There is considerable variability across people in their punitive responses to employee offenses in the workplace. We attempt to explain this variability by positing a novel antecedent of punishment: moral recognition. We find consistent evidence that identifying moral considerations and implications for workplace offenses predicts punitive responses toward employees who commit those offenses. Drawing on functional theoretical accounts of morality and punishment, we posit that people are motivated to punish others to the extent that they believe a moral offense has (...) been committed, because much of what it means to commit a moral offense (as opposed to a non-moral offense) is to act in a way that prevents, or inhibits, cooperative behavior to achieve social goals. Punishment can discourage group members from committing those offenses in the future, thereby regulating behavior in a way that facilitates cooperation and social cohesion. We offer correlational and causal evidence that the link between moral recognition and punishment is explained, in part, by participants’ beliefs that committing these offenses prevents cooperative behavior to achieve organization-related goals.

Ethics education has become a priority at many business schools. A common pedagogical strategy in business ethics education has been to encourage students to deliberate and reason about cases and dilemmas. However, relatively little is known about how students actually reason, by default, about business ethics cases and dilemmas. In a large-scale study with undergraduate management students, we investigate how students reason about ethical dilemmas in business. Our results suggest that, after making an initial decision in a dilemma, students rarely (...) changed their minds after deliberating over an extensive set of reasons for both sides of the dilemma. Students evaluated reasons in a way that preferentially supported their initial decisions. This post-hoc evaluation of reasons to preferentially support initial decisions also had implications for decision entrenchment: students actually tended to become more confident in the superiority of their initial decisions after deliberating over the reasons for both sides. We discuss the challenges that our findings pose for teaching business ethics. (shrink)

Followers of Wittgenstein allegedly once held that a meaningful claim to know that p could only be made if there was some doubt about the truth of p. The correct response to this thesis involved appealing to the distinction between the semantic content of a sentence and features attaching to its use. It is inappropriate to assert a knowledge-claim unless someone in the audience has doubt about what the speaker claims to know. But this fact has nothing to do with (...) the semantic content of knowledgeascriptions; it is entirely explicable by appeal to pragmatic facts about felicitous assertion. (shrink)

This chapter introduces the thesis of contextualism about knowledge attributions, which is the view that the proposition expressed by a sentence such as ‘John knows that the bank is open at 2 p.m. EST on October 3, 2006’ varies depending upon the context of its utterance. Different versions of the thesis are explained.

This chapter explains and develops a version of Interest-Relative Invariantism about knowledge, according to which whether or not someone knows that p at a certain time depends in part on what is at stake for them in being right about p at that time.
