Given that there is referential uncertainty (noise) when learning words, to what extent can forgetting filter some of that noise out, and be an aid to learning? Using a Cross Situational Learning model we find a U-shaped function of errors indicative of a “Goldilocks” zone of forgetting: an optimum store-loss ratio that is neither too aggressive nor too weak, but just the right amount to produce better learning outcomes. Forgetting acts as a high-pass filter that actively deletes (part of) the (...) referential ambiguity noise, retains intended referents, and effectively amplifies the signal. The model achieves this performance without incorporating any specific cognitive biases of the type proposed in the constraints and principles account, and without any prescribed developmental changes in the underlying learning mechanism. Instead we interpret the model performance as more of a by-product of exposure to input, where the associative strengths in the lexicon grow as a function of linguistic experience in combination with memory limitations. The result adds a mechanistic explanation for the experimental evidence on spaced learning and, more generally, advocates integrating domain-general aspects of cognition, such as memory, into the language acquisition process.

Diagnostic self-testing devices are being developed for many illnesses, chronic diseases and infections. These will be used in hospitals, at point-of-care facilities and at home. Designed to allow earlier detection of diseases, self-testing diagnostic devices may improve disease prevention, slow the progression of disease and facilitate better treatment outcomes. These devices have the potential to benefit both the individual and society by enabling individuals to take a more proactive role in the maintenance of their health and by helping society improve (...) health and reduce health costs. However, the full implications of future home-based diagnostic technology for individuals and society remain unclear due to their novelty. We argue that the development of diagnostic tools, especially for home use, will heighten a number of ethical challenges. This paper will explore some of the ethical implications of home-based self-testing diagnostic devices for the autonomous and relational dimensions of the person. This will be facilitated by examining the impact of diagnostic devices for individual autonomy, for the delivery of accurate diagnosis and for the personal significance of the information for the user. The latter will be examined using Charles Taylor's view of personhood and his emphasis on human agency and interpretation. While the ethical issues are not necessarily new, the development of home-based self-testing diagnostic devices will make issues regarding autonomy, accuracy of information and personal significance more and more demanding. This will be the case particularly when an individual's autonomous choices come into conflict with the person's relational responsibilities. (shrink)

This paper seeks to contribute to the discussion on national corporate social responsibility plans from the perspectives of the three logics as articulated in Caritas in Veritate, by using the Irish national CSR plan as an example. Good for Business, Good for the Community: Ireland’s National Plan on Corporate Social Responsibility 2014–2016 maintains that CSR activities can enable organisations to build relationships and trust with communities. One of the consequences of the 2008 financial crisis was the decrease in trust in (...) banking systems and in business more broadly. It is well recognised that relationships of trust are essential to the life of the market, the state and civil society. Pope Emeritus Benedict XVI’s Caritas in Veritate contends that corresponding to the life of the market, the state and civil society are three logics: the logic of exchange, the logic of public obligation and the logic of gift. This paper proposes that the normative framework of the three logics of Caritas in Veritate can be read into the Irish national CSR plan. This paper argues that the examples of CSR initiatives proffered by the plan could point organisations in the direction of the logic of gift and therefore enable the rebuilding of relationships of trust with citizens and communities.

Building on research regarding the influence of national identity salience on attitudes towards international institutions and the impact of nationalism on foreign policy preferences, in a case study of America, I explore the role of chauvinistic nationalism to understand its impact on attitudes towards international jurisdiction of punishment for alleged human rights violations by members of the American military. Using binomial regression of survey responses from the 2014 Cooperative Congressional Election Study, I find that respondents with higher levels of chauvinistic (...) nationalist sentiment also have higher levels of opposition to the jurisdiction of international legal institutions to prosecute members of a nation’s military. This study is the first of its kind to offer a systematic and multivariate explanation for public opinion towards the jurisdiction of international human rights institutions over a nation’s armed forces using national survey data.

This article attempts a contextual study of the origin and early development of August Kekulé's theory of aromatic compounds. The terminus a quo is essentially August Hofmann's coining of the modern chemical denotation of ‘aromatic’ in 1855; the terminus ad quem is the first full codification of Kekulé's theory in the sixth fascicle of his Lehrbuch der organischen Chemie, published in the summer of 1866. Kekulé's theory is viewed in context with the earlier and concurrent experimental work of such chemists (...) as Hermann Kolbe, Friedrich Beilstein, Rudolph Fittig, and Hugo Müller. The reception of the theory is briefly examined. Attention is paid to the role of Kekulé's molecular models and of his celebrated dream anecdote of the snake that seizes its own tail. The episode is used as a case study for the continuity of scientific progress, and to illustrate the close reciprocal interactions of hypothesis and experiment in the evolution of a scientific theory.

In mammals, the Y chromosome induces testis formation and thus male sexual development; in the absence of a Y chromosome, gonads differentiate into ovaries and female development ensues. Molecular genetic studies have identified the Y‐located testis determining gene SRY as well as autosomal and X‐linked genes necessary for gonadal development. The phenotypes resulting from mutation of these genes, together with their patterns of expression, provide the basis for establishing a hierachy of genes and their interactions in the mammalian sex determination (...) pathway.

This article describes two experiments on awareness in recognition memory for novel faces. Two kinds of awareness, recollective experience and feelings of familiarity in the absence of recollective experience, were measured by "remember" and "know" responses. Experiment 1 showed that "remember" but not "know" responses were reduced by divided attention at study. Experiment 2 showed that massed versus spaced repetition of faces in the study list had the opposite effects on "remember" and "know" responses. Massed repetition increased "know" responses and (...) reduced "remember" responses. Spaced repetition increased "remember" responses and reduced "know" responses. The results of both experiments replicate previous findings from the verbal domain in the domain of face recognition, and hence they increase the ecological validity of this experiential approach to memory and awareness and the generality of its database. These findings are discussed from a rehearsal perspective on factors influencing the two states of awareness and in relation to the alternative "process dissociation" procedure. (shrink)

Interpretations of human nature driven by scientific analyses of the origin and development of the human species often assume metaphysical naturalism. This generates restrictive and distortive accounts of key facets of human life and ethics. It fails to make sense of human altruism, and it operates within a wider philosophical framework that lacks explanatory power. The accounts of theistic evolution that seek to redress this, however, too easily fail to take sufficient account of the unique contribution of interpretations from a (...) specifically Christian epistemic base. The latter involve a Christological and, hence, eschatological approach which is intrinsic to the interpretation of human nature in light of the purpose and intentionality of the Creator. Phenomenological approaches to the nature of humanity lack the categories to distinguish between human nature as the object of divine intentionality and its present dysfunctional and, ultimately, subhuman state.

The importance of having ethical oversight in research that is carried out on humans is well established. Research ethics, which is mainly influenced by a biomedical ethical framework, aims to ensure that the well-being and the rights of research participants are upheld and that any potential risks and harms are reduced. However, research is also considered to be a social activity with social effects. Therefore the principles of Catholic Social Teaching as a framework for research ethics may be significant. This (...) paper outlines those principles and demonstrates how these principles may be used for: reflecting ethically on research , judging a research ethics proposal and providing guidelines for action in research.

In the twelfth century, when military orders were first being established, the custom of child oblation was in decline in western monasteries, and the novitiate was acquiring a new importance. New foundations of monks and regular canons sought to ensure that recruits were subjected to a period of testing and training before they made their profession, while at Cluny Peter the Venerable insisted on a probationary period of at least a month. Since the rules governing their conventual life were based (...) upon those of existing religious institutions, the military orders were inevitably influenced by these trends. They rejected the practice of child oblation and in most cases instituted a period of probation for recruits. (shrink)

The prioritisation of scarce resources has a particular urgency within the context of the COVID‐19 pandemic crisis. This paper sets out a hypothetical case of Patient X (who is a nurse) and Patient Y (who is a non‐health care worker). They are both in need of a ventilator due to COVID‐19 with the same clinical situation and expected outcomes. However, there is only one ventilator available. In addressing the question of who should get priority, the proposal is made that the (...) answer may lie in how the pandemic is metaphorically described using military terms. If nursing is understood to take place at the ‘frontline’ in the ‘battle’ against COVID‐19, a principle of military medical ethics—namely the principle of salvage—can offer guidance on how to prioritise access to a life‐saving resource in such a situation. This principle of salvage purports a moral direction to return wounded soldiers back to duty on the battlefield. Applying this principle to the hypothetical case, this paper proposes that Patient X (who is a nurse) should get priority of access to the ventilator so that he/she can return to the ‘frontline’ in the fight against COVID‐19.

Much have been written about marketing ethics. Virtually no published research, however, has examined what factors are related to the ethical conflict of salespeople. Such research is important because it could have direct implications for the management of sales personnel. This paper presents the results of an exploratory study that examined selected correlates of salespeople's ethical conflict. Implications for practitioners and academic are also provided.

The concept of missed care refers to an irrefragable truth that required nursing care, which is left undone, occurs in the delivery of health care. As a technical concept, missed care offers nurses the opportunity to articulate a problematic experience. But what are we to make of missed care from an ethical perspective? Can nurses be held morally responsible for missed care? Ethically speaking, it is generally accepted that if a person has a moral obligation to do something, s/he needs (...) to have the capacity to do it. If a person does not have the capacity to fulfil a moral obligation, then s/he cannot be held responsible for failing to do so. This is captured by the “ought implies can” (OIC) principle. This paper brings the OIC principle to the forefront of the discussion on missed care. It is contended that nurses – qua moral agents – may be discharged from a moral obligation to carry out a required caring act because of some inability that is not of their making and therefore may not be morally responsible for missed care. However, the OIC principle may not be applied to all situations of missed care depending on their causes. In addition, following in the thought of Sapontzis (The Southern Journal of Philosophy, 1991, XXIX, 383–393) it is contended that when an original obligation to deliver a required act of care cannot be fulfilled, other obligations may be generated as summed up in the “Principle of Making Amends” and the “Principle of Appropriate Feeling.” It is the view of this paper that these further principles could prevent the OIC principle from being used to simply excuse omissions of care from a normative standard and could support the view that nurses continue to have alternative obligations to make amends and to respond with appropriate feelings to missed care.

Social cognition refers to a discipline in which researchers seek to understand social phenomena in terms of models which emphasize the role of cognitive processes (e.g., attention, encoding, cognitive organization, storage, memory) in mediating social thought and action. Although social cognition is a relatively new field, it is important to note that social psychologists have long been concerned with many of the same issues that are central to cognitive science, such as how people store and retrieve information about their environment (...) in memory. Thus, it would be inaccurate to portray the emergence of social cognition as the first time that social psychologists have focused on the role of cognition in mediating social behavior. Nevertheless, it is true that in the mid‐to‐late 1970s, a branch of social psychology emerged which was unique in the extent to which it overlapped with the theoretical orientation of, and the methodological tools employed by, cognitive psychologists. It is this time period that most scholars peg as the era in which social cognition grew and matured as a discipline in its own right. (shrink)

In Sherrington's Loom, Alan McComas provides a historical account of the research that has led to recognition of key mechanisms underlying consciousness. Evidence is assembled from a rich variety of sources--neurological patients, animal behavior, laboratory studies, and especially brain stimulation and recording in humans and animals. Among the remarkable advances in the field has been the ability to identify nerve cells in the human brain that store memories of specific people, places, and objects. In addition to dealing with the (...) issue of "free will," the book assembles the information into possible working models for sensations, intentions, and actions. McComas concludes by considering the possibility of consciousness in artificially intelligent systems. (shrink)

The Pittsburgh protocol relies heavily on traditional moral distinctions, particularly the principle of double effect, to justify "managing" the dying process of a prospective organ donor in order to yield viable organs for transplantation. These traditional moral distinctions can be useful, particularly in casuistic or case-specific moral analysis, but their invocation here is unpersuasive, and potentially dangerous. The protocol relies on elaborate apologetics to avoid a candid confrontation with the moral challenge it poses—society's willingness to bring about the death of (...) one patient (in isolation and with potential discomfort) in order to benefit another patient. Not only will this protocol fail to solve the problem it purports to address, it threatens to undermine the delicate social accommodations by which we distinguish the living from the dead, permissible "allowings to die" from impermissible killings, and those from whom organs may be removed from those whose bodies must remain inviolate.

This essay examines the early career of the chemist Emil Erlenmeyer (1825–1909), focusing on his various endeavors in industrial consulting and entrepreneurship, and his eventual decisive turn, in 1862, to academic research and teaching. This case study offers insights into the developing relationship between theory-based academic research and artisanal and industrial practice in the German states during the 1850s and 1860s. Attention is paid to the relevance of this material to the contemporary historiography of “technoscience.”.

Memory and Amnesia: An Introduction provides a clear and comprehensive account of amnesia set in the context of our understanding of how normal memory operates. Part 1 provides the reader with an up-to-date survey of contemporary memory theories. Part 2 deals with amnesia, incorporating all important new developments, and focuses on the nature and explanation of the amnesic syndrome.

Acts of Christian forgiveness that run counter to natural inclinations and ethical intuitions raise questions about the nature of human identity and the basis of moral theology. An assessment of the biblical and theological warrant for Christian forgiveness challenges the ethical misappropriation of the language of covenant, torah and righteousness to that of contract, law and justice. The argument is made that forgiveness should be seen as normative—indeed, obligatory rather than supererogatory. A theological account is then provided of the conditions (...) under which our natural inclinations are transformed so as to facilitate an orientation of forgiveness. It is argued that the doctrines of the incarnation and human participation in the mind of Christ are axiomatic for interpreting the Christian life and thus moral theology. This leads to the conclusion that a combination of ‘reconciled exemplarism’ and ‘semantic externalism’ is key to the exposition of Christian ethics – the language of which tracks God’s historical engagement with humanity rather than denoting immanent, ethical categories.

This article argues thatPanegyricus LatinusXII(9), a speech performed before Constantine in Trier in 313c.e.following his defeat of Maxentius the previous year, acted as a crucial localized act of communication to the emperor. Through a series of allusions and the careful presentation of his narrative, the orator made a case for the continued political and cultural importance of Trier within the newly expanded Constantinian empire.

Though written corporate codes of ethics have been touted as a panacea for the embarrassments and uncertainties of the past two decades, the absence of clear evaluation procedures severely compromises their usefulness. An ethnographic study comparing development processes and compliance outcomes in large health care facilities and energy companies shows that neither of the two industries has encountered much success with a codes of ethics program. Companies that distribute copies of their code of ethics seldom ensure the process is completed (...) or that employees understand the purpose of the document, and staff responsible for the code give it a low priority relative to their overall responsibilities. Contrary to expectations, health care facilities are no more likely to develop or implement codes of ethics effectively than are energy companies. More extensive research is needed in order to generate the data necessary for the development of realistic standards for the evaluation of codes of ethics. (shrink)

The control of mRNA synthesis in the unicellular eukaryote Saccharomyces cerevisiae involves a number of promoter elements, including an upstream activation site (UAS), an RNA initiation element (RIE) and, for some genes, a form of negative element. The UAS is involved in the activation and regulation of transcription, whilst the RIE, which comprises a transcription initiation site (or I site), and often a TATA box, is responsible for the accurate positioning of the 5′ end of the mRNA. The mechanism whereby (...) these promoter elements interact involves specific protein‐DNA binding events and possibly alterations in chromatin structure. (shrink)

In light of an historical obsession with human error, Krueger & Funder (K&F) suggest that social psychologists should emphasize the strengths of social perception. In our view, however, absolute levels of accuracy (or error) in any given experiment are less important than underlying processes. We discuss the use of the process-dissociation procedure for gaining insight into the mechanisms underlying accuracy and error.
