Recently a gender-selective harvesting strategy has been proposed for possible control of aquatic invasive species, wherein females of the invasive species are harvested, whilst stocking the males (abbreviated as FHMS strategy) (Lyu et al. in Nat Resour Model 33(2):e12252, 2020). We consider the FHMS strategy with a weak Allee effect, and show that its extinction boundary need not be hyperbolic. To the best of our knowledge, this is the first example of a non-hyperbolic extinction boundary in two-compartment mating models structured (...) by sex. The model possesses a rich dynamical structure, with several local co-dimension one bifurcations occurring. We also show the occurrence of a global homoclinic bifurcation, which has applicability for large scale strategic bio-control. (shrink)

Consider manipulation in which one agent, avoiding force, threat, or fraud mobilizes some non-concern motive of another so as to induce this other to behave or move differently than she would otherwise have behaved or moved, given her circumstances and her initial ranking of concerns. As an instance, imagine that I get us to miss the opening of a play that I have grudgingly agreed to attend by engaging your sublimated compulsive tendency to check the stove when we are halfway (...) to the theatre. Such motive manipulation is, I take it, widely regarded as morally worrisome. If it really is morally worrisome, then we should be able to explain adequately why it is so. But existing condemnations of manipulation come up short in this regard. In this paper, I develop and defend a more plausible account of the moral status of this phenomenon. (shrink)

The Moral Foundations of Trust seeks to explain why people place their faith in strangers, and why doing so matters. Trust is a moral value that does not depend upon personal experience or on interacting with people in civic groups or informal socializing. Instead, we learn to trust from our parents, and trust is stable over long periods of time. Trust depends on an optimistic world view: the world is a good place and we can make it better. Trusting people (...) are more likely to give through charity and volunteering. Trusting societies are more likely to redistribute resources from the rich to the poor. Trust has been in decline in the United States for over 30 years. The roots of this decline are traceable to declining optimism and increasing economic inequality, which Uslaner supports by aggregate time series in the United States and cross-sectional data across market economies.

This paper examines Charles Peirce's graphical notation for first-order logic with identity. The notation forms a part of his system of "existential graphs," which Peirce considered to be his best work in logic. In this paper a Tarskian semantics is provided for the graphical system.

In support of the thesis that colours are examples of metaphysical simples, this article critiques arguments to the contrary. It is shown that facts about colour resemblance do not entail the complexity of colour, for such facts may explained by recourse to acts of seeing-as. The logic of colour and colour terms is adumbrated in support of this and used in a positive argument for the claim that colours are simple.

Octavian's decision in 28 B.C.E. to ban Egyptian cults from within the pomerium was not a sign of hostility to foreign cults, especially since the emperor himself arranged for the restoration of those shrines outside the city's religious boundary. Rather, his action served to reassert the Roman openness to foreign religions while at the same time underlining the distinctions between Roman and foreign religious practices. Using the pomerium to demarcate a clear boundary between Roman and non-Roman helped to reconstruct the (...) sense of Roman identity that had been shattered by the civil wars of the previous fifty years.

Contrary to Vaesen's argument that humans are unique with respect to nine cognitive capacities essential for tool use, we suggest that although such cognitive processes contribute to variation in tool use, it does not follow that these capacities arenecessaryfor tool use, nor that tool use shaped cognition per se, given the available data in cognitive neuroscience and behavioral biology.

A critique of Rorty's own provocative political philosophy, as well as an in-depth look at both the issues concerning the relationship between the public and the private, and arguments on the role of reason in liberal political discourse generally.

This paper explores how image worship was conceptualized and represented by Chinese authors during the first four centuries of Buddhist presence in China. Previous scholarship has argued that image worship was initially seen in China as a distinctively Buddhist practice, so much so that Buddhism was even known to the Chinese as the “Religion of Images”. By examining the history of the interpretation of this term, the evolution of stories about sacred images, and the presentation of image worship in debates (...) about the compatibility of Buddhism with Chinese culture, I will argue that image worship was first seen as a distinctly Buddhist or non-Chinese practice only in the late fifth century. Ironically, image worship came to be seen or represented as “foreign” only long after it had already become part of most forms of Chinese religion. (shrink)

Since the birth of bioethics, a persistent refrain has been that advances in science, technology, and health are occurring so quickly that they threaten to outpace society’s ability to understand and react to them. Genomics, big data, and synthetic biology preoccupy current scholarly and policy debates, just as organ transplantation, in vitro fertilization, human subjects research, and gene therapy did over the past forty years. But the history of bioethics is more than the topics it has addressed. It is also (...) the story of the people whose voices shaped its debates and built society’s capacity to manage the escalating pace of technological change.LeRoy Walters is one of those contributors who made a difference.

I analyzed 298 open-ended responses of undergraduate students who have been reported for cheating to the question, “What, if anything, would have stopped you from committing your act of academic dishonesty?” These responses included a few major themes: students pled ignorance of what constitutes academic dishonesty and the consequences/seriousness associated with violations; students tended to deflect blame, usually by saying that their professor could have done something differently (neutralization); students did not feel they had enough time, resources, and/or skills to (...) get the desired result without taking responsibility for this lack of time, resources, and/or skills (strain); students felt they did not manage their time well with accepting the blame for the poor time management; and that a bad grade was not an option. These data and results are discussed in relation to the extant literature on the topic. (shrink)

Rosenberg's The Thinking Self also takes Husserl to task. Without going into the details here, Rosenberg finds Husserl's reliance on retentions to be inadequate. Instead, Rosenberg proposes that previous representations enter into our unified, instantaneous awareness of a succession as ones of which we are aware that we are, or were, aware of; as items of so-called meta-awareness. But this account falls prey to the same worries as Husserl's. For again, it is by no means clear what a series of (...) awarenesses, meta-awarenesses, meta-meta-awarenesses, etc. have to do with the representation of a temporal series. (shrink)

RÉSUMÉ: Une «situation de choix paradoxal» est une situation dans laquelle un agent connaîtrait davantage de succès en regard des préférences qu’il a effectivement, si ces préférences étaient différentes de ce qu’elles sont. Supposons que les agents rationnels ne choisissent pas à l’encontre de leurs préférences, que leur choix n’est déterminé que par ces préférences, et que leurs préférences intrinsèques ne changent pas de façon spontanée, automatique et directe sous l’influence de la critique rationnelle. Même dans de telles hypothèses, les (...) agents rationnels peuvent résoudre optimalement un éventail de situations de choix paradoxal au moyen de mécanismes qui les amènent à réviser leurs préférences. Dans cet article, je présente et défends un tel modèle de révision rationnelle des préférences. (shrink)

For nearly two decades, the process of reviewing the ethical merit of research involving human subjects has been based on the application of principles initially described in the U.S. National Commission's Belmont Report, and later articulated more fully by Beauchamp and Childress in their Principles of Biomedical Ethics. Recently, the use of ethical principles for deliberating about moral problems in medicine and research, referred to in the pejorative sense as “principlism”, has come under scrutiny. In this paper we argue that (...) these principles can provide a foundation for the source of ethical appraisal of human research, but are not themselves wholly adequate for this purpose. Therefore, we further propose that (1) principles should be understood as heuristics that can be “specified” as described by DeGrazia (1992), and (2) that the principle‐based approach should be supplemented by formally incorporating “sensitivity to context” into the evaluation of clinical trials.

Academic dishonesty occurs at alarming rates in higher education. In the present study, we examined predictors of academic cheating behaviors, and beliefs in the acceptability of cheating, in disliked courses at two large universities, using structural equation modeling. Perceived mastery and extrinsic goal structures were related to beliefs about cheating but not cheating behaviors. Beliefs in the acceptability of cheating were more likely to be endorsed in math and science courses. College students were more likely to cheat and to believe (...) in the acceptability of cheating when they reported a high need for sensation. (shrink)

Aggressive medical and surgical interventions have not been clearly demonstrated to improve survival in neonates with trisomy 18; there are no data that demonstrates improved quality of life for these children after these interventions; and these interventions are clearly associated with significant morbidity, resource allocation, and cost.

Philosophy has long struggled to understand the nature of color. The central role color plays in our lives, in visual experience, in art, as a metaphor for emotions, has made it an obvious candidate for philosophical reflection. Understanding the nature of color, however, has proved a daunting task, despite the numerous fields that contribute to the project. Even knowing how to start can be difficult. Is color to be understood as an objective part of reality, a property of objects with (...) a status similar to shape and size? Or is color more like pain, to be found only in experience and so somehow subjective? Or is color more like what some have said about time--that it seems real until we reflect enough, where we come ultimately to dismiss it as mere illusion? If color is more like shape and size, can we give a scientific account of it? Various strategies exist for this option--taking the color of an object to be just a complicated texture of that object, one that reflects certain wavelengths. Or perhaps color is merely a disposition to cause experiences in us, as salt has a disposition to dissolve. On the other hand, if color is more like pain, and found only in subjective experience, what is the nature of color experience? How, for instance, does an experience of red differ from an experience of blue, or from an experience of pain for that matter? Finally, if color is mere illusion, how do we continue to be so taken in by that illusion and how can something unreal seem so real and important to us? (shrink)

In the section of the Critique of Pure Reason entitled The Amphiboly of Concepts of Reflection Kant writes:Suppose that an object is exhibited to us repeatedly but always with the same intrinsic determinations . In that case, if the object counts as object of pure understanding then it is always the same object, and is not many but only one thing . But if the object is appearance, then comparison of concepts does not matter at all; rather, however much everything (...) regarding these concepts may be the same, yet the difference of locations of these appearances at the same time is a sufficient basis for the numerical difference of the object itself. Thus in the case of two drops of water we can abstract completely from all intrinsic difference , and their being intuited simultaneously in different locations is enough for considering them to be numerically different.

Objective: There are benefits and risks of giving patients more granular control of their personal health information in electronic health record (EHR) systems. When designing EHR systems and policies, informaticists and system developers must balance these benefits and risks. Ethical considerations should be an explicit part of this balancing. Our objective was to develop a structured ethics framework to accomplish this. -/- Methods: We reviewed existing literature on the ethical and policy issues, developed an ethics framework called a “Points to (...) Consider” (P2C) document, and convened a national expert panel to review and critique the P2C. -/- Results: We developed the P2C to aid informaticists designing an advanced query tool for an electronic health record (EHR) system in Indianapolis. The P2C consists of six questions (“Points”) that frame important ethical issues, apply accepted principles of bioethics and Fair Information Practices, comment on how questions might be answered, and address implications for patient care. -/- Discussion: The P2C is intended to clarify whatis at stake when designers try to accommodate potentially competing ethical commitments and logistical realities. The P2C was developed to guide informaticists who were designing a query tool in an existing EHR that would permit patient granular control. While consideration of ethical issues is coming to the forefront of medical informatics design and development practices, more reflection is needed to facilitate optimal collaboration between designers and ethicists. This report contributes to that discussion. (shrink)

Only a small proportion of academically dishonest students ever receive an official report of academic dishonesty, and the sociology of deviance literature is ripe with studies illustrating disproportionalities in detecting, policing, and prosecuting crimes. This study addresses the degree to which disproportionalities exist in the application of relatively few official sanctions levied upon students for academic dishonesty. I compared the demographics of those who have been reported for cheating with those of an entire undergraduate student body and of self-reported cheaters (...) in the literature. I found that international students are much more likely than domestic students to get reported. (shrink)

Ethics should guide the design of electronic health records (EHR), and recognized principles of bioethics can play an important role. This approach was adopted recently by a team of informaticists designing and testing a system where patients exert granular control over who views their personal health information. While this method of building ethics in from the start of the design process has significant benefits, questions remain about how useful the application of bioethics principles can be in this process, especially when (...) principles conflict. For instance, while the ethical principle of respect for autonomy supports a robust system of granular control, the principles of beneficence and non-maleficence counsel restraint due to the danger of patients being harmed by restrictions on provider access to data. Conflict between principles has long been recognized by ethicists and has even motivated attacks on approaches that state and apply principles. In this paper we show how using ethical principles can help in the design of EHRs by first, explaining how ethical principles can and should be used generally, and then by, discuss how attention to details in specific cases can show that the tension between principles is not as bad as it initially appeared. We conclude by suggesting further ways in which the application of these (and other) principles can add value to the ongoing discussion of patient involvement in their health care. This is a new approach to linking principles to informatics design that we expect will stimulate further interest. (shrink)
