In this article, we focus on two issues, namely, the nature and onset of very early personal memories, especially for traumatic events, and the role of stress in long-term retention. We begin by outlining a theory of early autobiographical memory, one whose unfolding is coincident with emergence of the cognitive self. It is argued that it is not until this self emerges that personal memories will remain viable over extended periods of time. We illustrate this with 25 (...) cases of young children′s long-term retention of early traumatic events involving emergency room treatment. On the basis of both qualitative and quantitative analyses, we conclude that very young children retain limited memories for events which they commonly express behaviorally, coherent autobiographical memories are not constructed until the child develops a cognitive sense of self , autobiographical memories for traumatic events are essentially no different from those for nontraumatic events, stress is only related to long-term retention inasmuch as it is one variable that serves to make an event unique, and like nontraumatic events, traumatic memories lose peripheral details during the retention interval and retain the central components of the event. These results are discussed both in terms of their implications for theories of early autobiographical memory as well as the ways in which we might differentiate implanted memories and authentic memories for traumatic events.

High temporal resolution event-related brain potential and electroencephalographic coherence studies of the neural substrate of short-term storage in working memory indicate that the sustained coactivation of both prefrontal cortex and the posterior cortical systems that participate in the initial perception and comprehension of the retained information are involved in its storage. These studies further show that short-term storage mechanisms involve an increase in neural synchrony between prefrontal cortex and posterior cortex and the enhanced activation of long-term (...) memory representations of material held in short-term memory. This activation begins during the encoding/comprehension phase and evidently is prolonged into the retention phase by attentional drive from prefrontal cortex control systems. A parsimonious interpretation of these findings is that the long-term memory systems associated with the posterior cortical processors provide the necessary representational basis for working memory, with the property of short-term memory decay being primarily due to the posterior system. In this view, there is no reason to posit specialized neural systems whose functions are limited to those of short-term storage buffers. Prefrontal cortex provides the attentional pointer system for maintaining activation in the appropriate posterior processing systems. Short-term memory capacity and phenomena such as displacement of information in short-term memory are determined by limitations on the number of pointers that can be sustained by the prefrontal control systems. Key Words: coherence; event-related potentials; imaging; long-term memory; memory; short-term memory; working memory. (shrink)

SummaryIn 1968, a prospective study was started in collaboration with the Family Planning Association to try to provide a balanced view of the beneficial and harmful effects of different methods of contraception. This investigation is now in progress at seventeen clinics and over 17,000 women are under observation. At the time of recruitment, all these women were married white British subjects, aged 25–39 years, who voluntarily agreed to participate. Fifty-six per cent were using oral contraceptives, 25% were using a diaphragm (...) and 19% were using an intrauterine device. During follow-up each woman is questioned at return visits to the clinic and a record of pregnancies and their outcome, hospital referrals, changes in contraceptive methods and the results of cervical smears, is accumulated. Women who default are sent a postal questionnaire and, if this is not returned, are telephoned or visited in their homes to collect the necessary information.So far, data obtained during 56,000 woman-years of observation are available for analysis. Follow-up has been maintained with an annual lapse rate of about 0.3%due to withdrawal of co-operation or loss of contact; adherence to the method of contraception in use at recruitment has been reasonably good, and the reporting of pregnancies and hospital admissions appears to have been both reliable and unbiased.The present data include only 24 deaths, so the mortality associated with different contraceptive methods cannot yet be estimated. With regard to morbidity, however, our preliminary results closely resemble those obtained in the prospective study carried out by the Royal College of General Practitioners and in the principal retrospective studies carried out in Britain and the United States. Women who used oral contraceptives at the start of the study experienced adeficiencyof hospital referrals for cancer, benign lesions of the breast, menstrual disorders other than amenorrhoea, duodenal ulcer, and retention cysts of the ovary; they showed anexcessof referrals for cerebrovascular disease, cervical erosion, skin disorders, self-poisoning, migraine, venous thrombosis and embolism, hayfever, gallbladder disease, amenorrhoea, and sterility. Women who used a diaphragm showed adeficiencyof hospital referrals for carcinoma-in-situ and dysplastic lesions of the cervix uteri and accidental injury; and anexcessof referrals for haemorrhoids and cystitis. Women who used an IUD experienced anexcessof hospital referrals for anaemia, varicose veins and salpingitis. About half of these differences were predicted from other studies while some suggestive evidence already existed for a further five. Of the remaining six, some probably reflect the influence of selective factors or chance.Multiple pregnancies, stillbirths, malformations, the sex ratio and birthweight showed no consistent relationship to method of contraception. The outcome of unplanned pregnancies occurring in women using an IUD, however, was remarkably unfavourable both in terms of ectopic gestation and miscarriage.Clear evidence was found of impairment of fertility after discontinuation of oral contraceptives. Whether this is likely to lead to permanent sterility in some women is uncertain.The study has provided data on the efficacy of a wide variety of contraceptive methods. In general the failure rates are in keeping with those obtained in other large-scale studies, save that those for the diaphragm and the sheath are much lower than those usually quoted.The available evidence does not yet allow a final balance to be struck between the benefits and risks associated with the new methods of contraception that have become widely used during the last two decades. It seems clear, however, that there are no material risks associated with the use of the diaphragm apart from the risk of pregnancy and that there may be some unintended benefits. (shrink)

University students in the UK have encountered many challenges as a result of the COVID-19 pandemic. This research aimed to track the mental well-being of a large sample of British university students (n = 554) over a one-year period of the COVID-19 pandemic, capturing data at four time points between May 2020 and May 2021. Overall retention after 12 months was 34.73%. Findings showed the COVID-19 pandemic has caused a significant, negative impact on the well-being of British university students. (...) Students are suffering from prolonged and high levels of psychological distress and anxiety. Levels of flourishing in students are still very low. The different phases of the pandemic appear to have played an influential role in student mental health. The practical implications for higher education and recommendations for future research are discussed. (shrink)

We focus on the functional specificity of theta and alpha oscillations and show that theta is related to working memory, whereas alpha is related to semantic long-term memory. Recent studies, however, indicate that alpha oscillations also play an important role during short-term memory retention and retrieval. This latter finding provides support for the basic hypothesis suggested by Ruchkin et al.

This study explored the perceptions of ethics among long-term care employees (N275) in order to test two hypotheses. A cohort cross-sectional survey examined employees’ perceptions of an ethics environment, racial-ethnic, and position disparities (HO1; ANOVA), and, secondarily, ethics in relationship to select, research-grounded work features measured as manage disagreements, effectiveness, work satisfaction, and opinions of care, the latter including intention to remain (HO2; Pearson Correlations). Established questionnaires with robust psychometrics were employed. Response rate was 51%. Non-significant differences between (...) sample and population on key variables supported extrapolation of results. Statistically significant differences between racial–ethnic (p < 0.03; F 2.42) and work positions (p <0.0001; F 6.24) were revealed on ethics (3.16; HO1). Statistically significant relationships (p <0.0001; r = 0.26–0.68; HO2) between ethics and employees’ work features also were found, confirming both hypotheses. Perceptions of ethics based on racial-ethnic and position disparities, as well as the robust links with employee work features, offered potential avenues for decreasing disparities at work and improving the quality of long-term care. Noted further on ethics item scoring were relatively low scores indicating less involvement in, and access to, ethics discussions and decisions. In contrast, the literature review substantiated the importance of empowerment and retention, which were enhanced by employee involvement in work, notably, discussions and decisions. Thus, implications of ethics committees in long-term care sites as ways to potentially enhance employees’ work and quality of care, especially work satisfaction and retention, were explored; relevant concerns raised by the Covid pandemic were, briefly, discussed.

What might be called the “common approach” to teaching incorporates traditional retrieval exercises, such as tests and quizzes, as tools for evaluating retention. Given our course goals, many educators would recognize that the emphasis on retention is problematic. In addition to understanding information in the short-term, long-term understanding is also desirable. In this paper, I advocate for a new use of quizzes in philosophy courses that is intentionally designed to enhance long-term understanding of (...) course material as well as to develop skills that are applicable outside academic settings. These skills include learning to confront problems that do not have obvious solutions and revise beliefs in light of new information. I will specifically consider three iterations involved in developing this method. (shrink)

Consistent with Ruchkin and colleagues' proceduralist account, recent research on grouping and verbal-spatial binding in immediate memory shows continuity across short- and long-term retention, and activation of classes of information extending beyond those typically allowed in modular models. However, Ruchkin et al.'s account lacks well-specified mechanisms for the retention of serial order, binding, and the control of activation through attention.

Working-memory retention as activated long-term memory fails to capture orchestrated processing and storage, the hallmark of the concept of working memory. The event-related potential (ERP) data are compatible with working memory as a mental workspace that holds and manipulates information on line, which is distinct from long-term memory, and deals with the products of activated traces from stored knowledge.

With a history dating back at least 3000 years, the philosophical tradition of India is one of the oldest to continue to thrive today. Encompassing a wide variety of worldviews, Indian philosophy includes perspectives that have ongoing relevance to contemporary issues such as the nature of consciousness, the relationship between philosophy and the good life, the existence of a divine reality, and the meaning of happiness. Contrary to widespread stereotypes, Indian philosophy is not simply an extension of Indian religion. Scepticism (...) is a pervasive feature of this discourse, and there is even a school of thought which affirms materialism. The idea of a divine reality is debated extensively, not only in terms of the existence of such a reality-"Is there a God?"-but also in terms of its nature-"What is God?" This book, drawing upon some of the latest research in the field, traces the history of the Indian philosophical tradition from ancient times to the present, outlining the views and major thinkers of such schools of thought as Vedanta, Jainism, Buddhism, and many more. Jeffery D. Long treats each system, however, not simply as an historical artifact, but as a living reality with important insights to offer our world today. It is essential reading for anyone interested in world philosophies and how they address the 'big questions' that have always engaged human beings. (shrink)

in this article, we explore how responsible research and innovation (RRI) interacts with the current political context. We examine the (1) possible consequences for RRI and related agendas if values associated with ‘populist’ movements become more pervasive, (2) the role that a lack of RRI has potentially played in the development of this political context, and (3) how RRI as a concept, practice, and research agenda should respond. We argue that whilst RRI is threatened, it is now more important than (...) ever. We propose that RRI needs to go beyond being a method for facilitating societal input into research and innovation and for highlighting desired impacts. RRI needs to evolve to provide an effective conduit for criticisms and the input of critical thinking and reflexivity into science and innovation, including in terms of economic policy and politics.

Libertarianism needs a theory of class. This claim may meet with resistance among some libertarians. A few will say: “The analysis of society in terms of classes and class struggles is a specifically Marxist approach, resting on assumptions that libertarians reject. Why should we care about class?” A greater number will say: “We recognize that class theory is important, but libertarianism doesn't need such a theory, because it already has a perfectly good one.”.

The output feedback controller is designed for a class of stochastic nonlinear systems that satisfy uncertain function growth conditions for the first time. The multivariate function growth condition has greatly relaxed the restrictions on the drift and diffusion terms in the original stochastic nonlinear system. Here, we cleverly handle the problem of uncertain functions in the scaling process through the function maxima theory so that the Ito differential system can achieve output stabilization through Lyapunov function design and the solution of (...) stochastic nonlinear system objects satisfies the existence of uniqueness, ensuring that the system is globally asymptotically stable in the sense of probability. Furthermore, it is concluded that the system is inversely optimally stable in the sense of probability. Finally, we apply the theoretical results to the practical subsea intelligent electroexecution robot control system and obtain good results. (shrink)

Ethical consumption is on the rise, however little is known about the degree and the implications of the sometime conflicting sets of values held by the broad category of consumers who report consuming ethically. This paper explores convergence and divergence of ethical consumption values through a study of organic, fair trade, and local food consumers in Colorado. Using survey and focus group results, we first examine demographic and attitudinal correlates of ethical consumption. We then report evidence that while many organic, (...) fair trade, and local food consumers converge around similar values, some Colorado consumers support only local food, while opposing the consumption of organic and fair trade products. Next, we investigate how ethical consumers who converge and diverge frame their commitment to consuming ethically. The discussion and conclusion suggest that community development planners of projects that focus on ethical consumption will need to successfully traverse issues stemming from convergence and divergence to enjoy long-term sustained success.

This article analyses the production and reception of the natural history film series Secrets of Nature and its sequel Secrets of Life, exploring what these films reveal about the role of cinema in public discourses about science and nature in interwar Britain. The first part of the article introduces the Secrets using an ‘intermedial’ approach, linking the kinds of natural history that they displayed to contemporary trends in interwar popular science, from print publications to zoos. It examines how scientific knowledge (...) was communicated in the series, especially the appeal to everyday experience as a vehicle to engage mass audiences with scientific subjects. The second part examines the Secrets series through the lens of knowledge co-production, detailing how a range of different figures, including academic scientists, nature photographers, producers and teachers, became entangled in making the films. Recovering the term ‘ciné-biology’, it argues that Secrets developed a unique style of filmmaking that generated cultural space for the life sciences in British popular culture. The third part analyses two interwar cinema experiments to explore how audiences, imagined and real, shaped the kinds of natural knowledge characterized by the Secrets films. (shrink)

Berkeley, Hume, and Russell rejected the traditional analysis of substances in terms of qualities which are supported by an "unknowable substratum." To them the proper alternative seemed obvious. Eliminate the substratum in which qualities are alleged to inhere, leaving a bundle of coexisting qualities--a view that we may call the Bundle Theory or BT. But by rejecting only part of the traditional substratum theory instead of replacing it entirely, Bundle Theories perpetuate certain confusions which are found in the Substratum Doctrine. (...) I examine two major types of BT developed by Russell and by G. F. Stout with the intention of showing that (1) the seemingly innocuous concept of "a quality" employed by these versions cannot be used to state their theories coherently, and (2) the fatal problems that the BT encounters point to a more satisfactory and interesting alternative to both the Substratum Doctrine and the BT. This is a view that I call the Qualified Particulars Theory. In a final section I draw morals from this discussion that apply to the analogous Humean view that a mind is a "bundle of perceptions and sensations.". (shrink)

At the intersection of meta-ethics and philosophy of science, Nicholas Sturgeon’s “Moral Explanation” ([1985] 1988), Richard Boyd’s “How to be a Moral Realist” (1988), and David Brink’s Moral Realism and the Foundations of Ethics (1989) inaugurated a sustained argument for the claim that moral kinds like right action and virtuous agent are scientifically investigable natural kinds. The corresponding position is called “non-reductive ethical naturalism,” or “NEN.” Ethical nonnaturalists, by contrast, argue that moral kinds are genuine and objective, but not natural. (...) This dissertation is largely a challenge to non-reductive ethical naturalism from the viewpoint of ethical nonnaturalism. An introduction, four fairly independent chapters, and a conclusion comprise this dissertation. The introduction (chapter one) situates and summarizes the arguments in the four chapters that immediately follow, and the concluding chapter (chapter six) describes future work related to the arguments in this dissertation. I now turn to chapters two through five. In chapter two, I shore up what I believe are weakness in Derek Parfit’s Triviality Objection to reductive ethical naturalism and then present a challenge to the NEN theorist, which, I argue, the NEN theorist must but ultimately cannot meet. The challenge is to sketch an empirical experiment whereby we can adjudicate between competing moral hypotheses. I explain in terms of experimental design and evaluation why the challenge cannot be met. Chapters three and four focus on the semantics and reference relations of kind terms. In chapter three, I defend the Causal Externalist (CE) theory of semantics and reference against an objection distilled from two articles by Åsa Marie Wikforss. The objection is that CE implies a paradox, escape from which forces the CE theorist upon the horns of a dilemma. I show how the CE theorist can avoid the dilemma by allowing that the intensions of some artificial-kind terms (e.g., ‘jade’) are not given by descriptions associated with the terms. One consequence of this move, however, is that it casts doubt upon the coherence of the claim that moral-kind terms (e.g., ‘morally required action’) are natural-kind terms. In chapter four, I defend Terence Horgan and Mark Timmons’s Moral-Twin Earth argument from three critical responses put forward in recent paper by David Merli. NEN theorists claim that CE can account for the semantics and reference of moral-kind terms. As per Horgan and Timmons (H&T), however, our responses to the Moral-Twin Earth thought experiment give us reason to doubt the NEN theorists’ claim. Against H&T’s argument, however, Merli presents three independent, critical responses, and in this chapter I defend H&T’s argument in a way that is friendly to the ethical nonnaturalist. One upshot is, I contend, that the ethical nonnaturalist can and indeed should co-opt H&T’s argument for his own use. In chapter five, I return to kinds themselves, specifically those in biology. I first point out that ethical nonnaturalism appeals to a metaphysical thesis about nonnatural value, which need not be limited to the moral domain. Then, I argue that biological naturalism alone cannot give a satisfying realist account of biological kinds like HEART and NEURON. Finally, I show that by conjoining the concept of Cummins functions as recently defended by Paul Davies, a thesis about nonnatural value, and Ned Block’s Disney Principle regarding structural properties, the nonnaturalist, unlike the naturalist, can offer a satisfying realist account of biological kinds.

Moral metasemantic theories explain how our moral thought and talk are about certain properties. Given the connection between what our moral terms are about and which moral claims are true, it might be thought that metasemantic theorising can justify first-order ethical conclusions, thus providing a novel way of doing moral epistemology. In this paper, we spell out one kind of argument from metasemantic theories to normative ethical conclusions, and argue that it fails to transmit justification from premises to conclusion. We (...) give three reasons for this transmission failure, which together pose a serious challenge to such metasemantic arguments. (shrink)

The following is a prominent version of the causal theory of reference, held by certain moral philosophers and philosophers of science: (CTR) A general term 'T' rigidly designates a property F iff the use of 'T' by competent users of the term is causally regulated by F. In a series of papers, Terence Horgan and Mark Timmons present a thought experiment our intuitive responses to which provide evidence against (CTR). The present essay goes beyond Horgan and Timmons by (...) offering a metaphysical argument, according to which (CTR) implies the denial of any normative ethical theory. (shrink)
